A bearing portion 204 is provided on the bottom 201 of the device. The bearing portion 204 is screwed with the shaft portion 203 included in the leg 202. By rotating the shaft portion 203, the grounding portion 205 provided below the leg 202 can be moved up and down to adjust the height of the grounding portion 205.

　使用者は、機器の設置状態が安定するように接地部２０５の高さを設定し、軸受部２０４の下側に設けられたロックナット２０６を締め付けて固定する（例えば、特許文献１を参照）。 The user sets the height of the grounding portion 205 so that the installation state of the device is stable, and fastens and fixes the lock nut 206 provided on the lower side of the bearing portion 204 (see, for example, Patent Document 1). .

　しかしながら、このような従来の構成では、軸受部２０４に設けられた雌ねじ部２０７と、軸部２０３に設けられた雄ねじ部２０８との接触面において、隙間２０９，２１０が発生する。これらの隙間２０９，２１０の影響により、たとえロックナット２０６が強く締められたとしても、機器の運転に伴う振動、または時間経過に伴う機器の自重等によって螺合が緩んでしまう。すなわち、従来の構成では、軸部２０３が上下動して接地部２０５の高さ位置が変動し、機器の設置状況が安定しないという課題を有している。 However, in such a conventional configuration, gaps 209 and 210 are generated on the contact surface between the female screw portion 207 provided in the bearing portion 204 and the male screw portion 208 provided in the shaft portion 203. Due to the influence of these gaps 209 and 210, even if the lock nut 206 is tightened strongly, the screwing is loosened due to vibrations associated with the operation of the device or the weight of the device over time. That is, the conventional configuration has a problem that the shaft portion 203 moves up and down and the height position of the grounding portion 205 changes, and the installation state of the device is not stable.

FIG. 1 is a cross-sectional view showing the configuration of the device adjustment leg 11 according to the first embodiment of the present invention. FIG. 2A shows the state of the device adjustment leg 11 before the lock nut 6 is tightened. It is principal part sectional drawing, FIG. 2B is principal part sectional drawing which shows the state after tightening the lock nut 6 of the adjustment leg 11 for the apparatus. FIG. 3 is a perspective view of the bearing portion 4 of the device adjustment leg 11 according to the first embodiment of the present invention, and FIG. 4 is a perspective view of the leg 2 of the device adjustment leg 11.

　図１において、洗濯機、またはプロジェクタ等の電子・電器機器の底部１には、機器の設置状態を安定させるための機器用調整脚１１が設けられている。機器用調整脚１１は、底部１に設けられた軸受部４、脚２、および、脚２が有する軸部３を備えている。軸受部４は、軸部３と螺合している。使用者は、軸部３を回動させることにより、脚２の下部に設けられた接地部５を上下動させて、機器の高さを調整することができる。 Referring to FIG. 1, an adjustment leg 11 for equipment for stabilizing the installation state of equipment is provided at the bottom 1 of an electronic / electric equipment such as a washing machine or a projector. The device adjustment leg 11 includes a bearing portion 4 provided on the bottom portion 1, a leg 2, and a shaft portion 3 included in the leg 2. The bearing portion 4 is screwed with the shaft portion 3. The user can adjust the height of the device by rotating the shaft portion 3 to move the grounding portion 5 provided at the lower portion of the leg 2 up and down.

　軸受部４には、雌ねじ部７が設けられおり、軸部３には、雄ねじ部８が設けられている。雌ねじ部７の上面１２と雄ねじ部８の下面１３との間で、接触面が構成されている。接触面の両面それぞれには、リブが設けられている。具体的には、雌ねじ部７の上面１２に、第１のリブ１４が形成されており、雄ねじ部８の下面１３に、第２のリブ１５が形成されている。 The bearing portion 4 is provided with a female screw portion 7, and the shaft portion 3 is provided with a male screw portion 8. A contact surface is formed between the upper surface 12 of the female screw portion 7 and the lower surface 13 of the male screw portion 8. Ribs are provided on both surfaces of the contact surface. Specifically, the first rib 14 is formed on the upper surface 12 of the female screw portion 7, and the second rib 15 is formed on the lower surface 13 of the male screw portion 8.

　使用者は、機器の設置状態が安定するような位置に接地部５の高さを設定して、軸受部４の下側に設けられたロックナット６を締め付ける。なお、ロックナット６は、ロック部の一例であり、他の方法、または構成を用いることも可能である。 The user sets the height of the grounding portion 5 at a position where the installation state of the device is stabilized, and tightens the lock nut 6 provided on the lower side of the bearing portion 4. The lock nut 6 is an example of a lock portion, and other methods or configurations may be used.

　ロックナット６を締め付けることにより、雌ねじ部７の上面１２と、雄ねじ部８の下面１３との間に生じる隙間９が小さくなり、接触面に設けられた第１のリブ１４と第２のリブ１５とが互いに当接する。よって、螺合が緩まずに、安定した機器の設置状態が維持される。 By tightening the lock nut 6, the gap 9 generated between the upper surface 12 of the female screw portion 7 and the lower surface 13 of the male screw portion 8 is reduced, and the first rib 14 and the second rib 15 provided on the contact surface. Abut each other. Therefore, a stable installation state of the device is maintained without loosening.

　図２Ａに示したように、ロックナット６が締め付けられる前には、機器本体に作用する重力の影響で、雌ねじ部７の上面１２と雄ねじ部８の下面１３との間に生じる隙間９は比較的大きくなる。このとき、第１のリブ１４は第２のリブ１５と離間している。このような、第１のリブ１４と第２のリブ１５とが当接しない状態で、使用者は、軸部３を回動させることにより、接地部５を上下動させることができる。なお、このような状態のままで放置すると、機器の運転に伴う振動、または、時間経過に伴う機器の自重等によって、螺合が緩む場合がある。 As shown in FIG. 2A, before the lock nut 6 is tightened, the gap 9 generated between the upper surface 12 of the female screw portion 7 and the lower surface 13 of the male screw portion 8 is compared by the influence of gravity acting on the device body. Become bigger. At this time, the first rib 14 is separated from the second rib 15. In such a state where the first rib 14 and the second rib 15 are not in contact with each other, the user can move the grounding portion 5 up and down by rotating the shaft portion 3. If left in such a state, the screwing may be loosened due to vibration associated with the operation of the device, or the weight of the device over time.

　一方、図２Ａに示した状態において、第１のリブ１４と第２のリブ１５とが離間せず、隙間９が小さくなり、第１のリブ１４と第２のリブ１５とが当接するように、予め螺合条件が設定されていた場合を想定する。このような場合にも、使用者は、第１のリブ１４と第２のリブ１５とを当接させ、第２のリブ１５が第１のリブ１４を乗り越えることを繰り返しながら、軸部３を回動させ、接地部５を上下動させることができる。 On the other hand, in the state shown in FIG. 2A, the first rib 14 and the second rib 15 are not separated from each other, the gap 9 is reduced, and the first rib 14 and the second rib 15 are in contact with each other. Assume that the screwing conditions are set in advance. Even in such a case, the user brings the shaft portion 3 into contact with the first rib 14 and the second rib 15 and repeatedly moving the second rib 15 over the first rib 14. By rotating, the grounding part 5 can be moved up and down.

　この場合、第１のリブ１４と第２のリブ１５とが当接するように設定されている。よって、このような設置状態のままで放置したとしても、機器の運転に伴う振動、または時間経過に伴う機器の自重等によって、第２のリブ１５が第１のリブ１４を乗り越えるほどの作用は発生しない。すなわち、ロックナット６を締め付ける前であっても、第１のリブ１４と第２のリブ１５とを当接させることにより、螺合が緩む可能性を低減することができる。 In this case, the first rib 14 and the second rib 15 are set to contact each other. Therefore, even if it is left as it is in such an installation state, the action that the second rib 15 gets over the first rib 14 due to the vibration accompanying the operation of the equipment or the weight of the equipment with the passage of time, etc. Does not occur. That is, even before the lock nut 6 is tightened, the possibility that the screwing is loosened can be reduced by bringing the first rib 14 and the second rib 15 into contact with each other.

　次に、図２Ｂに示したように、ロックナット６を締め付けた後について説明する。この場合、ロックナット６と軸受部４とが当接し、軸部３が軸受部４に対して下方に引き寄せられる。よって、雌ねじ部７の上面１２と雄ねじ部８の下面１３との間に生じる隙間９は小さくなり、第１のリブ１４と第２のリブ１５とが容易に当接し、第１のリブ１４と第２のリブ１５とが当接する面積が、ロックナット６を締め付ける前よりも大きくなる。これにより、機器の運転に伴う振動、または時間経過に伴う機器の自重等によって、螺合が緩むことを防止することができる。 Next, as shown in FIG. 2B, the operation after the lock nut 6 is tightened will be described. In this case, the lock nut 6 and the bearing portion 4 come into contact with each other, and the shaft portion 3 is drawn downward with respect to the bearing portion 4. Therefore, the gap 9 generated between the upper surface 12 of the female screw portion 7 and the lower surface 13 of the male screw portion 8 is reduced, and the first rib 14 and the second rib 15 easily come into contact with each other. The area in contact with the second rib 15 is larger than before the lock nut 6 is tightened. Thereby, it is possible to prevent the screwing from being loosened due to vibrations associated with the operation of the device or due to the weight of the device over time.

　なお、使用者が、再び接地部５の高さ位置を調整する場合には、ロックナット６を緩めればよい。これにより、図２Ａに示した状態に戻るので、使用者は、高さ位置を容易に調整することができる。 In addition, what is necessary is just to loosen the lock nut 6 when a user adjusts the height position of the earthing | grounding part 5 again. Thereby, since the state shown in FIG. 2A is restored, the user can easily adjust the height position.

　図３に示したように、軸受部４に設けられた雌ねじ部７の上面１２には、複数の第１のリブ１４が構成されている。複数の第１のリブ１４は、螺合の中心軸、すなわち軸部３が挿入されて回動するときの回転軸を中心にして、放射状に等間隔に設けられている。 As shown in FIG. 3, a plurality of first ribs 14 are formed on the upper surface 12 of the internal thread portion 7 provided in the bearing portion 4. The plurality of first ribs 14 are provided radially at equal intervals around a central axis of screwing, that is, a rotation axis when the shaft portion 3 is inserted and rotated.

　また、図４に示したように、軸部３に設けられた雄ねじ部８の下面１３には、複数の第２のリブ１５が構成されている。複数の第２のリブ１５は、螺合の中心軸、すなわち軸部３が回動するときの回転軸を中心として、放射状に等間隔に設けられている。 Further, as shown in FIG. 4, a plurality of second ribs 15 are formed on the lower surface 13 of the male screw portion 8 provided in the shaft portion 3. The plurality of second ribs 15 are provided radially at equal intervals around a central axis of screwing, that is, a rotation axis when the shaft portion 3 rotates.

　ここで、隣接する複数の第１のリブ１４の間隔と、隣接する複数の第２のリブ１５の間隔とは、同一か、または、一方の間隔が他方の間隔の倍数の関係になっていることが望ましい。これにより、第１のリブ１４と第２のリブ１５とが同時に複数個当接することができ、螺合が緩むことをいっそう効果的に防止することができる。 Here, the interval between the plurality of adjacent first ribs 14 and the interval between the plurality of adjacent second ribs 15 are the same, or one interval is a multiple of the other interval. It is desirable. As a result, a plurality of the first ribs 14 and the second ribs 15 can be in contact with each other at the same time, and loosening of the screwing can be more effectively prevented.

　また、図４に示したように、第２のリブ１５を、雄ねじ部８の高さ方向の所定の範囲１６にわたって複数個設ける構成とすることが望ましい。これにより、軸部３の上下動に対して、第１のリブ１４と第２のリブ１５とが当接する範囲を拡大させることができるので、接地部５の高さの調整範囲が大きくなっても螺合が緩むことを防止できる。 Further, as shown in FIG. 4, it is desirable that a plurality of the second ribs 15 be provided over a predetermined range 16 in the height direction of the male screw portion 8. As a result, the range in which the first rib 14 and the second rib 15 abut against the vertical movement of the shaft portion 3 can be enlarged, so that the adjustment range of the height of the grounding portion 5 is increased. It is possible to prevent the screwing from being loosened.

　ただし、軸部３を上下動させて接地部５の高さ位置が設定された直後には、必ずしも第１のリブ１４と第２のリブ１５とが当接している必要はない。第１のリブ１４が、隣接する複数の第２のリブ１５の間に位置し、第１のリブ１４と第２のリブ１５とが当接しない状態で、ロックナット６が締め付け固定される構成であってもよい。この場合、機器の運転に伴う振動、または、時間経過に伴う機器の自重等によって徐々に螺合が緩んでも、やがて第１のリブ１４と第２のリブ１５とが当接して回転止めが構成される。よって、それ以上に螺合が緩むことはない。このとき、複数の第１のリブ１４の間隔、および複数の第２のリブ１５の間隔のうち、いずれか一方を他方よりも小さく設定することにより、螺合の緩みに伴って軸部３が上下動する範囲を小さくすることができる。 However, immediately after the shaft part 3 is moved up and down and the height position of the grounding part 5 is set, the first rib 14 and the second rib 15 do not necessarily have to contact each other. A configuration in which the first nut 14 is positioned between a plurality of adjacent second ribs 15 and the lock nut 6 is fastened and fixed in a state where the first ribs 14 and the second ribs 15 do not contact each other. It may be. In this case, even if the screwing is gradually loosened due to vibrations associated with the operation of the equipment or due to the weight of the equipment over time, the first rib 14 and the second rib 15 will eventually come into contact with each other to form a rotation stop. Is done. Therefore, the screwing does not loosen any further. At this time, by setting one of the intervals between the plurality of first ribs 14 and the intervals between the plurality of second ribs 15 to be smaller than the other, the shaft portion 3 can be moved along with the loosening of the screwing. The range of vertical movement can be reduced.

　なお、第１のリブ１４は、必ずしも雌ねじ部７の上面１２に複数設ける必要はない。第１のリブ１４を少なくとも一つ設けることにより、第１のリブ１４と、複数の第２のリブ１５の内のいずれかとを当接させて、螺合が緩むことを防止することができる。 Note that it is not always necessary to provide a plurality of first ribs 14 on the upper surface 12 of the female screw portion 7. By providing at least one first rib 14, the first rib 14 can be brought into contact with any one of the plurality of second ribs 15 to prevent loosening of the screwing.

　（第２の実施の形態）
　次に、本発明の第２の実施の形態について説明する。 (Second Embodiment)
Next, a second embodiment of the present invention will be described.

　図５は、本発明の第２の実施の形態における機器用調整脚２１の要部断面図である。 FIG. 5 is a cross-sectional view of the main part of the device adjustment leg 21 according to the second embodiment of the present invention.

　なお、本実施の形態における機器用調整脚２１の基本的な構成は、第１の実施の形態で説明した機器用調整脚１１と同様であるので、ここでは、異なる部分について詳細に説明する。本実施の形態においては、第１の実施の形態と比較して、第１のリブ１４、および第２のリブ１５が設けられる場所が異なる。 In addition, since the basic structure of the adjustment leg 21 for apparatuses in this Embodiment is the same as that of the adjustment leg 11 for apparatuses demonstrated in 1st Embodiment, a different part is demonstrated in detail here. In the present embodiment, the place where the first rib 14 and the second rib 15 are provided is different from that in the first embodiment.

　図５に示したように、本実施の形態において、軸受部４に設けられた雌ねじ部７と、軸部３に設けられた雄ねじ部８とで構成される接触面は、雌ねじ部７の下面１７と雄ねじ部８の上面１８との間に形成されている。雌ねじ部７の下面１７に第１のリブ１４が設けられ、雄ねじ部８の上面１８に第２のリブ１５が設けられている。 As shown in FIG. 5, in the present embodiment, the contact surface formed by the female screw portion 7 provided in the bearing portion 4 and the male screw portion 8 provided in the shaft portion 3 is the lower surface of the female screw portion 7. 17 and the upper surface 18 of the male screw portion 8. A first rib 14 is provided on the lower surface 17 of the female screw portion 7, and a second rib 15 is provided on the upper surface 18 of the male screw portion 8.

　使用者は、接地部５の高さ位置を調整する場合に、軸部３を軸受部４に対して下方に押し下げながら軸部３を回動させて、接地部５を上下動させる。軸部３を軸受部４に対して下方に押し下げることにより、雌ねじ部７の下面１７と雄ねじ部８の上面１８との間に生じる隙間１０が大きくなる。したがって、第１のリブ１４を第２のリブ１５と離間させ、第１のリブ１４、および第２のリブ１５を当接させずに、軸部３を回動させて上下動することができるので、容易に高さを調整することができる。 When adjusting the height position of the grounding portion 5, the user moves the grounding portion 5 up and down by rotating the shaft portion 3 while pushing the shaft portion 3 downward with respect to the bearing portion 4. By pressing the shaft portion 3 downward with respect to the bearing portion 4, the gap 10 generated between the lower surface 17 of the female screw portion 7 and the upper surface 18 of the male screw portion 8 is increased. Therefore, the first rib 14 can be moved up and down by rotating the shaft portion 3 without separating the first rib 14 from the second rib 15 and contacting the first rib 14 and the second rib 15. So the height can be adjusted easily.

　本実施の形態の機器用調整脚２１の構成によれば、軸部３を上下動させて接地部５の高さ位置を設定し、機器を設置した後に、必ずしもロックナット６による締め付けを行う必要はない。これは、機器本体に作用する重力の影響で、雌ねじ部７の下面１７と雄ねじ部８の上面１８との間に生じる隙間１０は小さくなり、第１のリブ１４と第２のリブ１５とが互いに容易に当接し、螺合が緩まず、安定した機器の設置状態を維持することができるからである。 According to the configuration of the device adjustment leg 21 according to the present embodiment, the shaft portion 3 is moved up and down to set the height position of the grounding portion 5, and after the device is installed, the lock nut 6 needs to be tightened. There is no. This is due to the influence of gravity acting on the device main body, and the gap 10 formed between the lower surface 17 of the female screw portion 7 and the upper surface 18 of the male screw portion 8 is reduced, and the first rib 14 and the second rib 15 are separated. This is because they can be easily brought into contact with each other, the screwing is not loosened, and a stable installation state of the device can be maintained.

　また、本実施の形態においても、軸部３を上下動させて接地部５の高さ位置を設定した直後に、第１のリブ１４と第２のリブ１５とを、必ずしも当接させておく必要はない。第１のリブ１４が、隣接する複数の第２のリブ１５の間に位置し、第１のリブ１４と第２のリブとが当接しない状態で機器を設置してもよい。この場合、機器の運転に伴う振動、または時間経過に伴う機器の自重等によって、徐々に螺合が緩んでも、やがては第１のリブ１４と第２のリブ１５とが当接して回転止めが構成されるので、それ以上に螺合が緩むことはない。複数の第１のリブ１４の間隔、または、複数の第２のリブ１５の間隔のうち、いずれか一方を他方よりも小さく設定することにより、螺合の緩みに伴う軸部３の上下動する範囲を小さくすることができる。 Also in the present embodiment, the first rib 14 and the second rib 15 are always brought into contact with each other immediately after the shaft portion 3 is moved up and down to set the height position of the grounding portion 5. There is no need. The first rib 14 may be located between the plurality of adjacent second ribs 15, and the device may be installed in a state where the first rib 14 and the second rib are not in contact with each other. In this case, even if the screwing is gradually loosened due to vibrations associated with the operation of the device or the weight of the device over time, the first rib 14 and the second rib 15 will eventually come into contact with each other to prevent rotation. Since it is configured, the screwing does not loosen any further. By setting either one of the intervals between the plurality of first ribs 14 or the intervals between the plurality of second ribs 15 to be smaller than the other, the shaft portion 3 moves up and down as the screwing is loosened. The range can be reduced.

　なお、本実施の形態においても、第１のリブ１４は、必ずしも雌ねじ部７の下面１７に複数設けなくともよい。少なくとも一つの第１のリブ１４を設けることにより、第１のリブ１４と、複数の第２のリブ１５のうちのいずれかとを当接させて、螺合が緩むことを防止することができる。 In the present embodiment as well, a plurality of the first ribs 14 are not necessarily provided on the lower surface 17 of the female screw portion 7. By providing at least one first rib 14, the first rib 14 can be brought into contact with any one of the plurality of second ribs 15 to prevent loosening of the screwing.

　以上述べたように、本発明の実施の形態の機器用調整脚１１，２１は、機器の底部１に設けられた軸受部４と、軸受部４に螺合し、上下動可能に設けられた軸部３と、軸部３を有する脚２とを備えている。また、軸受部４に設けられた雌ねじ部７と、軸部３に設けられた雄ねじ部８と、雌ねじ部７の、雄ねじ部８との接触面に設けられた第１のリブ１４と、雄ねじ８部の、雌ねじ部７との接触面に設けられた第２のリブ１５とを備えている。 As described above, the device adjusting legs 11 and 21 according to the embodiment of the present invention are screwed into the bearing portion 4 provided on the bottom portion 1 of the device and are capable of moving up and down.

　（第３の実施の形態）
　次に、本発明の第３の実施の形態について説明する。 (Third embodiment)
Next, a third embodiment of the present invention will be described.

　図６は、本発明の第３の実施の形態における機器用調整脚１１１の構成を示す断面図であり、図７Ａは、同機器用調整脚１１１の、ロックナット１０６を締め付ける前の状態を示す要部断面図であり、図７Ｂは、同機器用調整脚１１１の、ロックナット１０６を締め付けた後の状態を示す要部断面図である。また、図８は、本発明の第３の実施の形態における機器用調整脚１１１のロックナット１０６を下方から見た斜視図であり、図９は、同機器用調整脚１１１の脚１０２の斜視図である。 FIG. 6 is a cross-sectional view showing the configuration of the device adjustment leg 111 according to the third embodiment of the present invention. FIG. 7A shows the state of the device adjustment leg 111 before the lock nut 106 is tightened. It is principal part sectional drawing, FIG. 7B is principal part sectional drawing which shows the state after tightening the lock nut 106 of the adjustment leg 111 for the apparatus. FIG. 8 is a perspective view of the lock nut 106 of the device adjustment leg 111 according to the third embodiment of the present invention as viewed from below, and FIG. 9 is a perspective view of the leg 102 of the device adjustment leg 111. FIG.

　図６において、洗濯機、またはプロジェクタ等の電気・電子機器の底部１０１には、機器の設置状態を安定させるための機器用調整脚１１１が設けられている。機器用調整脚１１１は、底部１０１に設けられた軸受部１０４、脚１０２、および、脚１０２が有する軸部１０３を備えている。軸受部１０４は、軸部１０３と螺合している。使用者は、軸部１０３を回動させることにより、脚１０２の下部に設けられた接地部１０５を上下動させて、機器の高さを調整することができる。 In FIG. 6, an adjustment leg 111 for equipment for stabilizing the installation state of the equipment is provided on the bottom 101 of an electric / electronic equipment such as a washing machine or a projector. The device adjustment leg 111 includes a bearing 104 provided on the bottom 101, a leg 102, and a shaft 103 included in the leg 102. The bearing portion 104 is screwed with the shaft portion 103. The user can adjust the height of the device by rotating the shaft portion 103 to move the grounding portion 105 provided at the lower portion of the leg 102 up and down.

　使用者は、機器の設置状態が安定するような位置に接地部１０５の高さを設定して、軸受部１０４の下側に設けられたロックナット１０６を締め付ける。なお、ロックナット１０６は、ロック部の一例であり、他の方法、または構成を用いることも可能である。 The user sets the height of the grounding portion 105 at a position where the installation state of the device is stabilized, and tightens the lock nut 106 provided on the lower side of the bearing portion 104. The lock nut 106 is an example of a lock portion, and other methods or configurations may be used.

　ロックナット１０６には、雌ねじ部１６１が設けられており、軸部１０３には、雄ねじ部１０８が設けられている。雌ねじ部１６１の下面１１２と雄ねじ部１０８の上面１１３との間で、接触面が構成されている。接触面の両面それぞれには、リブが設けられている。具体的には、雌ねじ部１６１の下面１１２に、第１のリブ１１４が形成されており、雄ねじ部１０８の上面１１３に、第２のリブ１１５が形成されている。 The lock nut 106 is provided with a female screw portion 161, and the shaft portion 103 is provided with a male screw portion 108. A contact surface is formed between the lower surface 112 of the female screw portion 161 and the upper surface 113 of the male screw portion 108. Ribs are provided on both surfaces of the contact surface. Specifically, the first rib 114 is formed on the lower surface 112 of the female screw portion 161, and the second rib 115 is formed on the upper surface 113 of the male screw portion 108.

　ロックナット１０６を締め付けることにより、雌ねじ部１６１の下面１１２と、雄ねじ部１０８の上面１１３との間に生じる隙間１０９が小さくなり、接触面に設けられた、第１のリブ１１４と第２のリブ１１５とが互いに当接する。よって、螺合が緩まずに、安定した機器の設置状態が維持される。 By tightening the lock nut 106, a gap 109 formed between the lower surface 112 of the female screw portion 161 and the upper surface 113 of the male screw portion 108 is reduced, and the first rib 114 and the second rib provided on the contact surface are reduced. 115 abut against each other. Therefore, a stable installation state of the device is maintained without loosening.

　図７Ａに示したように、ロックナット１０６が締め付けられる前には、機器本体に作用する重力の影響で、雌ねじ部１６１の下面１１２と雄ねじ部１０８の上面１１３との間に生じる隙間１０９は比較的大きくなる。このとき、第１のリブ１１４は第２のリブ１１５と離間している。このような、第１のリブ１１４と第２のリブ１１５とが当接しない状態で、使用者は、軸部１０３を回動させることにより、接地部１０５を上下動させることができる。なお、このような状態のままで放置すると、機器の運転に伴う振動、または、時間経過に伴う機器の自重等によって、螺合が緩む場合がある。 As shown in FIG. 7A, before the lock nut 106 is tightened, the gap 109 generated between the lower surface 112 of the female screw portion 161 and the upper surface 113 of the male screw portion 108 due to the influence of gravity acting on the device body is compared. Become bigger. At this time, the first rib 114 is separated from the second rib 115. In such a state where the first rib 114 and the second rib 115 are not in contact with each other, the user can move the grounding portion 105 up and down by rotating the shaft portion 103. If left in such a state, the screwing may be loosened due to vibration associated with the operation of the device, or the weight of the device over time.

　一方、図２Ａに示した状態において、第１のリブ１１４と第２のリブ１１５とが離間せず、隙間１０９が小さくなり、第１のリブ１１４と第２のリブ１１５とが当接するように、予め螺合条件が設定されていた場合を想定する。このような場合にも、使用者は、第１のリブ１１４と第２のリブ１１５とを当接させ、第２のリブ１１５が第１のリブ１１４を乗り越えることを繰り返しながら、軸部１０３を回動させ、接地部１０５を上下動させることができる。 On the other hand, in the state shown in FIG. 2A, the first rib 114 and the second rib 115 are not separated from each other, the gap 109 is reduced, and the first rib 114 and the second rib 115 are in contact with each other. Assume that the screwing conditions are set in advance. Even in such a case, the user brings the shaft portion 103 into contact with the first rib 114 and the second rib 115, and repeatedly moving the second rib 115 over the first rib 114. By rotating, the grounding part 105 can be moved up and down.

　この場合、第１のリブ１１４と第２のリブ１１５とが当接するように設定されている。よって、このような設置状態のままで放置したとしても、機器の運転に伴う振動、または時間経過に伴う機器の自重等によって、第２のリブ１１５が第１のリブ１１４を乗り越えるほどの作用は発生しない。すなわち、ロックナット１０６を締め付ける前であっても、第１のリブ１１４と第２のリブ１１５とを当接させることにより、螺合が緩む可能性を低減することができる。 In this case, the first rib 114 and the second rib 115 are set to contact each other. Therefore, even if it is left in such an installation state, there is an effect that the second rib 115 gets over the first rib 114 due to the vibration caused by the operation of the device or the weight of the device over time. Does not occur. That is, even before the lock nut 106 is tightened, the possibility that the screwing is loosened can be reduced by bringing the first rib 114 and the second rib 115 into contact with each other.

　次に、図７Ｂに示したように、ロックナット１０６を締め付けた後について説明する。この場合、ロックナット１０６と軸受部１０４の下面とが当接し、軸部１０３が軸受部１０４に対して下方に引き寄せられる。よって、雌ねじ部１６１の下面１１２と雄ねじ部１０８の上面１１３との間に生じる隙間１０９は小さくなり、第１のリブ１１４と第２のリブ１１５とが容易に当接し、第１のリブ１１４と第２のリブ１１５とが当接する面積が、ロックナット１０６を締め付ける前よりも大きくなる。これにより、機器の運転に伴う振動、または時間経過に伴う機器の自重等によって、螺合が緩むことを防止することができる。 Next, as shown in FIG. 7B, a description will be given after the lock nut 106 is tightened. In this case, the lock nut 106 and the lower surface of the bearing portion 104 come into contact with each other, and the shaft portion 103 is drawn downward with respect to the bearing portion 104. Therefore, the gap 109 formed between the lower surface 112 of the female screw portion 161 and the upper surface 113 of the male screw portion 108 is reduced, and the first rib 114 and the second rib 115 easily come into contact with each other. The area in contact with the second rib 115 is larger than before the lock nut 106 is tightened. Thereby, it is possible to prevent the screwing from being loosened due to vibrations associated with the operation of the device or due to the weight of the device over time.

　なお、使用者が、再び接地部１０５の高さ位置を調整する場合には、ロックナット１０６を緩めればよい。これにより、図７Ａに示した状態に戻るので、使用者は、高さ位置を容易に調整することができる。 In addition, what is necessary is just to loosen the lock nut 106, when a user adjusts the height position of the grounding part 105 again. Thereby, since the state shown in FIG. 7A is restored, the user can easily adjust the height position.

　図８に示したように、ロックナット１０６に設けられた雌ねじ部１６１の下面１１２には、複数の第１のリブ１１４が構成されている。複数の第１のリブ１１４は、螺合の中心軸、すなわち軸部１０３が挿入されて回動するときの回転軸を中心にして、放射状に等間隔に設けられている。 As shown in FIG. 8, a plurality of first ribs 114 are formed on the lower surface 112 of the female thread portion 161 provided in the lock nut 106. The plurality of first ribs 114 are provided radially at equal intervals around a central axis of screwing, that is, a rotation axis when the shaft portion 103 is inserted and rotated.

　また、図９に示したように、軸部１０３に設けられた雄ねじ部１０８の上面１１３には、複数の第２のリブ１１５が構成されている。複数の第２のリブ１１５は、螺合の中心軸、すなわち軸部１０３が回動するときの回転軸を中心として、放射状に等間隔に設けられている。 Further, as shown in FIG. 9, a plurality of second ribs 115 are formed on the upper surface 113 of the male screw portion 108 provided in the shaft portion 103. The plurality of second ribs 115 are provided radially at equal intervals around a central axis of screwing, that is, a rotation axis when the shaft portion 103 rotates.

　ここで、隣接する複数の第１のリブ１１４の間隔と、隣接する複数の第２のリブ１１５の間隔とは、同一か、または、一方の間隔が他方の間隔の倍数の関係になっていることが望ましい。これにより、第１のリブ１１４と第２のリブ１１５とが同時に複数個当接することができ、螺合が緩むことをいっそう効果的に防止することができる。 Here, the interval between the plurality of adjacent first ribs 114 and the interval between the plurality of adjacent second ribs 115 are the same, or one interval is a multiple of the other interval. It is desirable. Thereby, a plurality of the first ribs 114 and the second ribs 115 can be in contact with each other at the same time, and it is possible to more effectively prevent the screwing from being loosened.

　また、図９に示すように、第２のリブ１１５を、雄ねじ部１０８の高さ方向の所定の範囲１１６にわたって複数個設ける構成とすることが望ましい。これにより、軸部１０３の上下動に対して、第１のリブ１１４と第２のリブ１１５とが当接する範囲を拡大させることができるので、接地部１０５の高さの調整範囲が大きくなっても螺合が緩むことを防止できる。 Also, as shown in FIG. 9, it is desirable to provide a plurality of second ribs 115 over a predetermined range 116 in the height direction of the male screw portion 108. As a result, the range in which the first rib 114 and the second rib 115 abut against the vertical movement of the shaft portion 103 can be expanded, so that the adjustment range of the height of the grounding portion 105 is increased. It is possible to prevent the screwing from being loosened.

　ただし、軸部１０３を上下動させて接地部１０５の高さ位置が設定された直後には、必ずしも第１のリブ１１４と第２のリブ１１５とが当接している必要はない。第１のリブ１１４が、隣接する複数の第２のリブ１１５の間に位置し、第１のリブ１１４と第２のリブ１１５とが当接しない状態で、ロックナット１０６が締め付け固定される構成であってもよい。この場合、機器の運転に伴う振動、または、時間経過に伴う機器の自重等によって徐々に螺合が緩んでも、やがて第１のリブ１１４と第２のリブ１１５とが当接して回転止めが構成される。よって、それ以上に螺合が緩むことはない。このとき、複数の第１のリブ１１４の間隔、および複数の第２のリブ１１５の間隔のうち、いずれか一方を他方よりも小さく設定することにより、螺合の緩みに伴って軸部１０３が上下動する範囲を小さくすることができる。 However, immediately after the shaft portion 103 is moved up and down and the height position of the ground contact portion 105 is set, the first rib 114 and the second rib 115 are not necessarily in contact with each other. A configuration in which the first rib 114 is positioned between a plurality of adjacent second ribs 115 and the lock nut 106 is fastened and fixed in a state where the first ribs 114 and the second ribs 115 are not in contact with each other. It may be. In this case, even if the screwing is gradually loosened due to vibrations associated with the operation of the device or due to the weight of the device over time, the first rib 114 and the second rib 115 eventually come into contact with each other to form a rotation stop. Is done. Therefore, the screwing does not loosen any further. At this time, by setting one of the intervals between the plurality of first ribs 114 and the intervals between the plurality of second ribs 115 to be smaller than the other, the shaft portion 103 can be moved along with the loosening of the screwing. The range of vertical movement can be reduced.

　なお、第１のリブ１１４は、必ずしもロックナット１０６に設けられた雌ねじ部１６１の下面１１２に複数設ける必要はない。第１のリブ１１４を、少なくとも一つ設けることにより、第１のリブ１１４と、複数の第２のリブ１１５のうちのいずれかとを当接させて、螺合が緩むことを防止することができる。 Note that it is not always necessary to provide a plurality of the first ribs 114 on the lower surface 112 of the female thread portion 161 provided on the lock nut 106. By providing at least one first rib 114, the first rib 114 can be brought into contact with any one of the plurality of second ribs 115 to prevent loosening of the screwing. .

　なお、本実施の形態においては、ロックナット１０６の雌ねじ部１６１の下面１１２に第１のリブ１１４を形成し、軸部１０３の雄ねじ部１０８の上面１１３に第２のリブ１１５を形成した例を用いて説明を行ったが、本発明はこの例に限定されない。例えば、ロックナット１０６の雌ねじ部１６１の上面に第１のリブ１１４を形成し、軸部１０３の雄ねじ部１０８の下面に第２のリブ１１５を形成することによっても、同様の効果を得ることができる。 In the present embodiment, an example in which the first rib 114 is formed on the lower surface 112 of the female screw portion 161 of the lock nut 106 and the second rib 115 is formed on the upper surface 113 of the male screw portion 108 of the shaft portion 103. Although described with reference to the present invention, the present invention is not limited to this example. For example, the same effect can be obtained by forming the first rib 114 on the upper surface of the female screw portion 161 of the lock nut 106 and forming the second rib 115 on the lower surface of the male screw portion 108 of the shaft portion 103. it can.

　以上述べたように、本実施の形態の機器用調整脚１１１は、機器の底部１０１に設けられた軸受部１０４と、軸受部１０４に螺合し、上下動可能に設けられた軸部１０３と、軸部１０３を有する脚１０２と、軸受部１０４の下側に設けられ、脚１０２の上下動を固定するロック部であるロックナット１０６とを備えている。また、機器用調整脚１１１は、ロック部に設けられた雌ねじ部１６１と、軸部１０３に設けられた雄ねじ部１０８と、雌ねじ部１６１の、雄ねじ部１０８との接触面に設けられた第１のリブ１１４と、雄ねじ部１０８の、雌ねじ部１６１との接触面に設けられた第２のリブ１１５とを備えている。 As described above, the device adjustment leg 111 of the present embodiment includes the bearing portion 104 provided on the bottom portion 101 of the device, and the shaft portion 103 that is screwed into the bearing portion 104 and provided so as to be movable up and down. , A leg 102 having a shaft portion 103, and a lock nut 106 provided on the lower side of the bearing portion 104 and serving as a lock portion for fixing the vertical movement of the leg 102. In addition, the device adjustment leg 111 includes a female screw portion 161 provided in the lock portion, a male screw portion 108 provided in the shaft portion 103, and a first contact surface provided on the contact surface of the female screw portion 161 with the male screw portion 108. And a second rib 115 provided on the contact surface of the male screw portion 108 with the female screw portion 161.

　このような構成により、ロック部であるロックナット１０６の雌ねじ部１６１と軸部１０３の雄ねじ部１０８との接触面に設けられた、第１のリブ１１４と第２のリブ１１５とが互いに当接する。よって、螺合が緩まず、安定した機器の設置状態を維持することができる。 With such a configuration, the first rib 114 and the second rib 115 provided on the contact surface between the female screw portion 161 of the lock nut 106 serving as the lock portion and the male screw portion 108 of the shaft portion 103 come into contact with each other. . Therefore, the screwing is not loosened, and a stable device installation state can be maintained.

　また、雌ねじ部１６１はロック部に設けられ、雌ねじ部１６１の下面に第１のリブ１１４が設けられ、雄ねじ部１０８の上面に第２のリブ１１５が設けられている。 Also, the female screw portion 161 is provided in the lock portion, the first rib 114 is provided on the lower surface of the female screw portion 161, and the second rib 115 is provided on the upper surface of the male screw portion 108.
