Description

  The present invention relates to a structure of a sit harness for preventing fall used during snow lowering work.

  A sit harness is a type of mountain climbing equipment that absorbs shocks when falling around the waist, and is the mainstream of climbing harnesses in Japan. There are two types: L'Egrund type, which has a belt that can absorb shocks in the thigh, and Wilans type, which can be attached and detached while wearing a crampon.

  On the other hand, the safety belt is a device intended to ensure safety by hanging the worker safely even if the worker is dropped, and is required to be worn at the work site. Yes. In addition, the safety belt to be worn is strictly standardized in terms of structure and strength. However, for example, when it comes to “snow-lowering work”, even in heavy snow areas where many snow-removal operations are required every year, it is often the case that a single lifeline is not worn in addition to the safety belt.

JP 2004-321562 A Japanese Patent Laid-Open No. 10-5371

  Therefore, as a matter of course, it is preferable to wear a safety belt even in the case of snow removal work on a home roof. In addition to the falling from the roof, there are many cases where the snow slides on the ground during the snow removal work and falls into the waterway. Therefore, it is preferable to wear a safety belt even on the ground. However, unlike those who work at heights, the safety band for general people is manufactured based on strict standards, so it is heavy, expensive, and has a complicated structure. Is not easy. The safety guaranteed by the safety belt is based on the premise that the safety belt is worn by an appropriate method, and may be dangerous even if it is improperly worn. Furthermore, it is necessary to consider that the snow removal work safety belt, which is often used by the elderly in snowy countries, can be used without burden on the elderly.

  Therefore, if the present inventor is a person who does not carry out snow removal work (for example, a person who performs snow removal on the roof of his / her home), the occupational safety and health law Article 42, Article 21-2, Article 26 Since it does not correspond to workers, etc., it is safe to use anything that is not a safety belt defined by these laws, so we focused on the fact that it is possible to use the climbing equipment sit harness as a safety belt during snow removal work. However, even if this is simply used, the sit harness is an assembly of a number of belts, and is easily entangled and twisted, and it is not easy to return it to the original state when it is attached. Moreover, in order to prevent slipping, it is only necessary to stop sliding instantaneously when a foot is slipped due to an accidental factor. However, a normal sit harness does not have such a function of stopping sliding. The invention of Patent Literature 2 proposes a sliding stop device having a non-slip member provided with a piercing portion on a wearer's buttocks. Each stab portion of the anti-slip member related to the sliding stop tool is formed to incline downward according to the tip, and when the wearer has a buttocks, the stab portion immediately hits the slope, causing the sliding to occur early. You are going to be able to stop. However, as shown in the name, the piercing part has a sharp tip, which may hurt a part of the human body, for example, a hand when worn, which is difficult in terms of safety.

  In order to solve the above problems, the sit harness for lowering snow according to the embodiment extends downward from a range of at least 120 degrees to 270 degrees out of a waist belt, a pair of thigh belts, and 360 degrees on the entire circumference of the waist belt, Between the range of the waist belt and the portion corresponding to the range of the thigh belt, a hip pad provided so as to cover the entire user's buttocks, on the opposite side of the hip pad, The waist belt and the pair of thigh belts are open.

  That is, it can be said that the above-mentioned sit-down harness for reducing snow reduces the twisting and entanglement of the belt. In addition, the conventional Lae Group-type sit harness is a belt that has a waist belt and thigh belts connected and integrated with several belts. is there. In a state where the fixing by the fixing tool is released, a large number of belts are entangled, and it is difficult to distinguish even before and after the harness. It can be said that the present invention has acquired ease of mounting by facilitating this discrimination.

  The “sit harness” in the present application is of a reggroup type. In mountaineering equipment, “harness” generally refers to “le group type”, and conversely “sit harness” generally refers to “willance type”. In this specification, it is different from a general way of saying. Therefore, the sit-down harness for lowering snow has a waist belt and a thigh-belt belt, as in the case of a conventional mountain climbing “sill group-type sit harness”. And the structure about a waist belt and a thigh belt is basically the same as that of a conventional product (climbing equipment), and is not particularly limited in the present invention. That is, both the waist belt and the thigh belt are loop-shaped, and are provided with a detachable fixing tool. By attaching it to the waist and thighs in the removed state, they are attached by rotating them around and connecting. In addition, this fixture usually has a belt length adjusting mechanism, but this is not particularly limited. However, in the present application, it is desirable that the fixing portion is located on the front side of the body when worn, and particularly on the waist belt, it should not be provided on the back side of the body.

  The buttocks are literally members that cover the wearer's buttocks when worn, and are the greatest feature of the present application. This is a fabric disposed on the back side portions of the waist belt and the left and right thigh belts, and is formed by sewing. If each of the waist belt and the left and right thigh belts is considered as a “line”, it can be said that among these “lines”, the back side of the wearer's body is connected by a “face” as the buttocks. First, the “wires” are less likely to twist or entangle because they are connected by faces. Second, since there is a “face” only on the back side of the body, the wearer has the consciousness that “the face is behind the back” or “wear the face so that it hits the hips” As long as you have it, you will be able to wear it properly, and the possibility of incorrect wearing will be drastically reduced.

  The buttocks are disposed on the back side of the waist belt and the left and right thigh belts, but the boundary between the “back” and the “front” is not particularly defined. Even if the buttocks have advanced to a portion that can be seen when the wearer is viewed from the front while wearing the snow-sitting sit-harness, there is no functional inconvenience unless the entire front is covered. In addition, when the wearer is viewed from the back side, it is not necessary that the entire back side is a butting part. There is also the possibility of problems such as twisting itself. Judging from the above viewpoint, it seems that it is in the range of 120 degrees to 270 degrees that the buttocks are arranged and the effect is high in the entire circumference of the waist 360 degrees. However, this numerical value does not limit the present invention.

  It does not specifically limit about the material of the cloth which comprises a buttocks part. Considering the field environment of snow removal work, a tough material excellent in water resistance is preferable, and mesh fabric is preferable in terms of reducing the weight of the member. Of course, as will be described later, it is possible to add a device such as attaching a non-slip tape, or stitching a plurality of pieces into one buttocks in order to follow the shape of the buttock.

Even if it is not only a steep slope, but also a gentle slope, when you slip your feet on snow or ice, you usually stick your hips, and you can slip off the roof or keep it on the waterway. It will fall. In the present invention, attention is paid to the curved surface shape of the buttocks of the wearer in a state where the sit harness for lowering snow is worn, and a plurality of protrusions are formed on the buttocks portion so as to protrude partly or entirely on the surface. And a non-slip member provided with a rib. The anti-slip member may be made of rubber and / or resin.
Further, the buttocks are a base part formed of soft rubber or soft resin as a raw material, and a plurality of spike pins arranged in a plurality of holes formed in the base part, and are hard rubber or hard You may make it provide the spike pin formed using resin as a raw material. If the height of the tip of the spike pin is configured to be the same as or lower than the surface of the base part, the base part formed of a soft rubber or soft resin under load will exert pressure. On the other hand, the spike pin formed of hard rubber or hard resin has a deformation rate smaller than that of the base part even when subjected to pressure, so the tip of the spike pin is deformed due to the difference in compression ratio of the deformation rate. It will stab and bite snow and ice, exhibit braking resistance and prevent slipping. Further, when the butt is held in the snow-free or ice-free state, the spike pin does not pierce the roof surface or the road surface, and only the base portion is deformed, and it is also possible to prevent the sliding off.

  Since it is a product for preventing falling used during snow removal work, ropes such as main ropes and lanyards are indispensable, and carabiners for connecting these ropes are also indispensable, but in the structure of the present invention itself There is no limitation on these.

  The sit harness for lowering snow according to the embodiment extends downward from a range of at least 120 degrees to 270 degrees out of a waist belt, a pair of thigh belts, and a total circumference of 360 degrees of the waist belt. A hip pad provided so as to cover the entire user's buttocks up to a portion corresponding to the range of the belt, and on the opposite side of the hip pad, the waist belt and the pair of thighs It is characterized by being open to the belt and is an extremely advanced invention having the following effects.

(1) Since the sit harness of the mountain climbing equipment is improved, it is lighter and less expensive than the conventional safety belt for working at high places.
(2) Since a part of the belt, which is likely to cause troubles such as tangling and twisting, is fixed by connecting with a cloth, such troubles are unlikely to occur.
(3) Installation is very easy because the fabric part comes to the buttocks as if wearing pants, and there is no possibility of wearing the front and back by mistake.
(4) Since the anti-slip mechanism is provided in the buttocks, the anti-slip effect is exhibited when the buttocks are held.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In each figure, the same number is attached | subjected to the same part, and the overlapping description is abbreviate | omitted. It should also be noted that the drawings may be exaggerated to understand the present invention and are not necessarily shown to scale. In addition, this invention is not limited to the Example shown below.

  Example 1 will be described in detail with reference to the drawings.

  FIG. 1 is a schematic perspective view showing an example of a sit-down harness 1 for lowering snow according to the present invention (hereinafter simply referred to as “the present invention harness 1”) viewed obliquely from the front (however, lanyards and the like are not depicted) ). As is apparent from the figure, the harness 1 of the present example is based on a reggroup-type sit harness and is composed of a waist belt 2, thigh belts 3 (two), and the like. However, the buttocks 4 which are not in the same type as the conventional are provided in the harness 1 of the present invention.

  A belay loop 5 is provided at a substantially central position on the front side of the thigh belt 2. This is a carabiner installation location for connecting to a mother rope via a lanyard by a carabiner, and is configured by a belt having excellent strength in a ring shape. In addition, a connecting belt 6 is passed through the thigh belt 3 extending from the front position of the left and right thigh belts 3 in the ring of the belay loop 5, and the load at the time of dropping or sliding is distributed to both thighs. There is work. (Note that drawing of carabiner, lanyard, master rope, etc. is omitted.)

  FIG. 2 shows a state where the harness 1 of the present invention of FIG. 1 is actually worn as seen from the rear. The buttocks 4 are present on the back side of the wearer. Therefore, the material fabric (mesh fabric in this example) of the buttocks 4 is approximately half the circumference of the back of the waist belt 2 and the thigh belt 3 (two It is stretched by sewing so as to connect approximately half of the back of the book. As a result, the fabric is present only in the portion applied to the buttocks of the wearer, and if it is recognized, the front and rear of the harness 1 of the present invention will not be mistaken.

  In the case of conventional leg group type sit harnesses, a narrow belt called a rear strap is often provided for the purpose of facilitating wearing by holding a large number of thigh belts 3. In the harness 1, the presence of the buttocks 4 has already achieved this purpose, and it is not necessary to provide it. (Of course, since a rear strap is not necessarily provided, a structure with a rear strap also belongs to the scope of the present invention.)

Two accessory rings 21 are installed on the back side of the waist belt 2 of this example, and are made of nylon that can hang a tool or the like necessary for snow-lowering work. However, this is not a member that requires load bearing strength. In that sense, it is fragile, but a load bearing rope (main rope) must not be connected here. Therefore, it is also a legitimate choice to omit the attachment of the accessory ring 21 from the viewpoint of avoiding erroneous connection.

  The waist belt 2 and the left and right thigh belts 3 of the harness 1 of the present invention both have a fixing hook 7 and are detachable. The fixing hook 7 of this example has a buckle structure and has a length adjusting mechanism that fixes the belt end portion with an appropriate length, but is separate from the fixing hook 7. A member may be provided and may have a length adjusting function (not shown). It should be noted that these fixing hooks 7 are preferably provided on the front side from the viewpoint of operability, but in the case of the present invention, the buttocks 4 are provided on the back side. Therefore, it is essential to provide the front side.

  FIG. 3 is a schematic development view of the harness 1 of the present invention shown in FIG. 1, wherein (a) is a view from the front, and (b) is a view of the harness 1 of the present invention. The expanded state is shown. 3 (a) shows the inner part of the harness 1 of the present invention, that is, the mounting surface for the body, while FIG. 3 (b) shows the outer part of the harness 1 of the present invention. In Example 1, as shown in FIG.2 and FIG.3 (b), the anti-slip | slipping tape 41 is sewn on the outer surface of the buttocks pad part 4. As shown in FIG.

  Next, the non-slip tape 41 will be described in more detail with reference to FIG. 4A and 4B are diagrams showing the non-slip tape 41 shown in FIG. 2, wherein FIG. 4A is a plan view, FIG. 4B is a side view, and FIG. 4C is a side view showing a modified form of FIG. In the first embodiment, the anti-slip tape 41 is made of rubber and is sewn to the buttock mesh with a synthetic resin thread so as to horizontally traverse substantially the center of the buttock mesh corresponding to the buttocks 4. That is, the anti-slip tape 41 includes a rubber base portion 410 and a convex portion 411 that protrudes by sewing the base portion 410 to the buttocks mesh with a synthetic resin thread. Therefore, when an operator wearing the harness 1 of the present invention loses balance on the slope of the roof or the ground and rolls over, the buttocks tend to stick, but when the buttocks are put on, the center of weight is applied to the buttocks 4 can be expected to prevent slipping by the rubber base portion 410 and the synthetic resin convex portion 411 of the anti-slip tape 41 attached to 4. In addition, the convex part 412 shown in FIG.3 (c) is comprised higher than the height of the convex part 411 shown in (b), and the convex part 411 is on the surface of the snow and ice laminated | stacked on the roof surface and the ground surface. The anti-slip effect is enhanced by piercing.

  Example 2 will be described in detail with reference to the drawings. The second embodiment is characterized in that attention is paid to the function improvement of the anti-slip tape 41 and an anti-slip mechanism instead.

  Please refer to FIG. FIGS. 5A and 5B are views showing a non-slip member 42 of the snow harness sit harness 1 according to the second embodiment of the present invention, where FIG. 5A is a perspective view, FIG. 5B is a plan view, and FIG. 5C is a side view. . The anti-slip member 42 includes a base portion 420 and horizontal ribs 421. The base portion 420 is made of rubber like the anti-slip tape 41 of the first embodiment, and is sewn to the buttock mesh with a synthetic resin thread so as to horizontally cross substantially the center of the buttock mesh corresponding to the buttocks 4. The Four horizontal ribs 421 protrude from the surface of the base portion 420 and are arranged at a predetermined interval. Each rib 421 is joined to the base part 420 by adhesion. Note that the number of horizontal ribs 421 is arbitrary and is not limited to four. Further, both the horizontal rib 421 and the base 420 may be integrally formed with rubber, or may be integrally formed with a flexible urethane resin. Further, the horizontal rib 421 may be made of hard plastic.

  Hereinafter, the operation of the second embodiment will be described. The worker wears the harness 1 of the present invention when performing snow removal. As mentioned above, when an operator loses balance on the slope of the roof or on the ground and falls over while snow is falling, he often sticks his hips. On the slope, if the center of gravity of the weight is parallel to the slope when the butt is held, the horizontal rib 421 of the anti-slip member 42 attached to the butt pad 4 bites into the snow surface and slides down with great resistance. It can be expected to prevent. In addition, when the place having a butt is not a snow surface but an exposed roof surface or road surface, the surface portion sandwiched between the loaded horizontal rib 421 and the substrate 420 exhibits braking resistance and prevents sliding. I can expect that.

  Please refer to FIG. FIG. 6 shows a modification of the anti-slip member shown in FIG. FIG. 6A will be described. The anti-slip member 43 includes a base portion 430, horizontal ribs 431 and 432, and vertical ribs 433 and 434. The base part 430 is made of rubber like the base part 420 shown in FIG. 5, and is sewn to the buttock mesh with a synthetic resin thread so as to horizontally cross substantially the center of the buttock mesh corresponding to the buttocks 4. The On the surface of the base part 430, vertical ribs 433 and 434 protrude and be arranged at the left and right ends, respectively, and two horizontal ribs 431 and 432 protrude between the vertical ribs 433 and 434, at a predetermined interval. Has been placed. The description of the same content as the anti-slip member 42 according to FIG. 5 is omitted.

  Hereinafter, the operation of the anti-slip member 43 according to FIG. When the center of gravity of the weight is parallel to the slope when the butt is held on the slope, the horizontal ribs 431 and 432 of the anti-slip member 43 attached to the butt pad 4 bite into the snow surface and become a great resistance. Preventing slipping is the same as in the case of the anti-slip member 42. On the other hand, when the center of gravity of the body weight is perpendicular to the slope when the butt is held on the slope, that is, when it slides sideways, the vertical ribs 433 and 434 of the anti-slip member 43 attached to the buttocks 4 are snowed. It can be expected that it will bite into the surface and become a great resistance to prevent slipping. Further, when the place having the butt is not the snow surface but the exposed roof surface or road surface, the same as the case of the anti-slip member 42 is performed.

  FIG. 6B will be described. The anti-slip member 44 includes a base portion 440, inclined ribs 441, 442, 443, 444 and vertical ribs 445, 446. Vertical ribs 445 and 446 are formed on the surface of the base portion 440 so as to protrude from the left and right ends, and inclined ribs 441 and 442 are formed in an inverted V shape above the vertical rib 445 and the vertical rib 446. Two inclined ribs 443 and 444 protrude in a V shape below the vertical rib 445 and the vertical rib 446, and are arranged at predetermined intervals. The description of the same content as the anti-slip member 42 according to FIG. 5 is omitted.

  Hereinafter, the operation of the anti-slip member 44 according to FIG. In the case of slipping from the foot when the center of gravity of the weight is parallel to the slope when the butt is held on the slope, the inclined ribs 443 and 444 of the non-slip member 44 attached to the buttocks 4 are on the snow surface. It bites in and becomes a great resistance to prevent slipping. In the case of slipping from the head when the center of gravity of the weight is parallel to the slope when the butt is held on the slope, the inclined ribs 441 and 442 of the anti-slip member 44 attached to the buttocks 4 on the snow surface It bites in and becomes a great resistance to prevent slipping. On the other hand, when the center of gravity of the weight is perpendicular to the slope when the butt is held on the slope, that is, when it slides sideways, the vertical ribs 445 and 446 of the anti-slip member 44 attached to the buttocks 4 are snow. It is the same as the case of the anti-slip member 43 according to FIG.

  Embodiment 3 will be described in detail with reference to the drawings. Example 3 focuses on the curved shape of the buttocks of the wearer in the state of wearing the snow-lowering sit harness in the present invention, and the buttocks are formed to protrude partly or entirely on the surface. An anti-slip member provided with a plurality of ribs is provided.

  Please refer to FIG. FIG. 7: is a schematic perspective view which shows the place which looked at the sit harness 10 for snow removal which concerns on Example 3 of this invention from back. Similarly to the sit-down harness 1 for lowering snow according to the first embodiment, the buttocks 14 are present on the back side of the wearer, and the material fabric of the buttocks 14 is approximately half of the back of the waist belt 12. The thigh belts 13 (two) are stretched by sewing so as to connect about half the circumference of the back side. As shown in FIG. 7, the buttocks pad 14 includes inclined ribs 141, 142, 143, 144, 145, 146, 147, and 148. The inclined ribs 141, 142, 143, 144, 145, 146, 147, 148 are joined to the buttocks 14 by adhesion at a predetermined interval. More specifically, the inclined ribs 141 and 142 project in a V shape above the center of the buttocks 14, and the inclined rib 143 and the inclined rib 144 project in a reverse V shape below the center of the buttocks. Are arranged at predetermined intervals. Further, the inclined ribs 145 and 146 protrude in a V shape toward the center of the buttocks 14, and the inclined ribs 147 and 148 are symmetrical at the center of the inclined ribs 145 and 146 and the buttocks 14. It is formed to project in a V shape. Note that the number of inclined ribs is arbitrary and is not limited to eight. Further, both the inclined rib and the buttocks 14 may be integrally formed of rubber, or may be integrally formed of flexible urethane resin.

  Hereinafter, the operation of the third embodiment will be described. In the case of slipping from the foot when the center of gravity of the weight is parallel to the slope when the butt is held on the slope, the inclined ribs 143, 144, 146, 148 attached to the buttocks 14 bite into the snow surface. Prevents slipping, becoming a great resistance. If the center of gravity of the body is slipping from the head when the butt is held on the slope, the inclined ribs 141, 142, 145, 147 bite into the snow surface, and the resistance is high. To prevent slipping. On the other hand, in the case where the center of gravity of the body weight is perpendicular to the slope when the butt is held on the slope, and the seat harness 10 slides to the left as viewed from the rear, the inclined ribs 141, 143, 145, 146 Intrusions into the snow surface and becomes a great resistance to prevent slipping, and if it also slides to the right, the inclined ribs 142, 144, 147 and 148 bite into the snow surface and become a great resistance to prevent slipping .

Embodiment 4 will be described in detail with reference to the drawings. Example 4 is characterized in that an anti-slip mechanism is applied to the surface structure of the buttocks.

  Please refer to FIG. FIGS. 8A and 8B are views showing a snow harness sit harness 100 according to a fourth embodiment of the present invention, in which FIG. 8A is a schematic perspective view showing the position viewed from the rear, and FIG. 8B is an enlarged view of an X portion of FIG. (C) is a cross-sectional view of (b), and (d) is a schematic enlarged view of a part of (c). As shown in FIG. 8A, as in the case of the sit-down harnesses 1 and 10 according to the first and third embodiments, the buttocks 104 are on the back side of the wearer. This material fabric is stretched by sewing so as to connect about a half circumference on the back side of the waist belt 12 and about a half circumference on the back side of the thigh belts 13 (two).

  With reference to FIGS. 8B, 8 </ b> C, and 8 </ b> D, the anti-skid mechanism according to the fourth embodiment will be described in detail. FIG. 8B is an enlarged view of the portion X shown in FIG. 8A. The cross section is shown in FIG. 8C, and a further enlarged portion of the cross section is shown in FIG. ). Referring to FIG. 8 (d), the buttocks rest part 104 includes a base part 1040 and a plurality of spike pins 1041. The base portion 1040 may be formed of soft rubber or soft resin, with a plurality of holes drilled at a predetermined interval on the surface thereof. On the other hand, the spike pin 1041 is a so-called spike pin-shaped product with a pointed tip, and is preferably disposed in the hole of the base portion 1040 and molded from hard rubber or hard resin. 8C and 8D, the spike pin 1041 has a tip that is substantially the same height as the surface of the base portion 1040, but does not protrude from the surface of the base portion 1040. Preferably it is formed.

  Hereinafter, the operation of the fourth embodiment will be described. On the slope, when the center of weight is applied to any part of the buttocks 104 when the buttocks are gripped, the base 1040 formed of soft rubber or soft resin under load is deformed by pressure. . On the other hand, since the deformation rate of the spike pin 1041 formed of hard rubber or hard resin is smaller than that of the base portion 1040 even when subjected to pressure, the tip of the spike pin 1041 is snowed due to the difference in compression ratio of the deformation rate. It will stab and bite into the ice, exhibit braking resistance and prevent slipping. Further, when the butt is stuck in the snow-free or ice-free state, the spike pin 1041 does not pierce the roof surface or the road surface, and only the base portion 1040 is deformed, which also prevents the sliding off. it can.

  While the preferred embodiments of the sit harness according to the present invention have been illustrated and described above, it will be understood that various modifications can be made without departing from the technical scope of the present invention. For example, the fixing hook structure may be modified to achieve more reliable or simple fixing, or by adopting a hook-and-loop fastener, the belt end can be locked, or a light tool or the like can be used. If it can be fastened, the convenience is further improved.

  The sit harness according to the present invention can be widely used for those who do not perform snow removal work as business, for example, those who perform snow removal on a roof at home. It can also be widely used when work other than snow removal that involves the risk of sliding down, such as high places, is not carried out as work.
