It is attached to the annular recess 28 of the shaft 22.

 Next, the operation and the like of the stand device 1 will be described.

 [0029] When the stand device 1 is used, the leg 4 is gripped, and the base 4 of the leg 4 is centered on the shaft 22 of the bolt member 23 with respect to the base 2 with respect to the base 2. Turn it approximately 90 degrees downward until it touches 29, so that it is in a generally horizontal deployment.

 At this time, there is no need to operate the lock operating body 5, and the engaging portion 55 of the lock operating body 5 comes out of the second engaging recess 32 of the base body 2 as the leg 4 rotates, Thereafter, the biasing force of the spring 6 enters the first engaging recess 31 of the base body 2 and engages with the first engaging recess 31. As a result, the leg 4 is made substantially horizontal by the lock operating body 5. It is locked in the deployment usage state.

Thus, as shown in FIG. 2, the stand device 1 is substantially arranged on the placement portion 8 such as a floor surface. The three legs 4 in the horizontal unfolded and used state are stably self-supporting, and a supported object such as a lighting device or a camera is attached to the upper end of the support 3. When the leg 4 shown in FIG. 2 is in the deployed and used state, only the slippery contact part 40 of the leg 4 is in contact with the placement part 8, and therefore, the stand that supports the supported object. It is possible to easily move the entire apparatus 1 on the placement part 8.

 [0032] When the stand device 1 is not used, as shown in Fig. 3, the lock operating body 5 is piled up against the spring 6 and moved with respect to the leg 4 to engage the lock operating body 5. The part 55 is taken out of the first engaging recess 31 of the base body 2 to bring the lock operating body 5 into the unlocked state.

 Subsequently, the leg body 4 is gripped, and the leg body 4 is moved upward with respect to the base body 2 around the shaft portion 22 of the bolt member 23 until the elastic contact portion 46 contacts the outer peripheral surface of the support 3. Rotate approximately 90 degrees to the substantially vertical folding state along the support 3.

 At this time, the engaging portion 55 of the lock operating body 5 enters the second engaging recess 32 of the base 2 by the biasing force of the spring 6 and engages with the second engaging recess 32. Due to the engagement between the engagement portion 55 of the lock operating body 5 and the second engagement recess 32, the leg 4 is held in a substantially vertical folding non-use state.

 In this way, as shown in FIG. 1, the stand device 1 stably stands by itself only on the base 2 on the placement portion 8 such as the floor surface, and stores in the corner of the photographing room or the like in this standing posture. Stored in place. Note that only the contact portion 10 of the base 2 is in contact with the placement portion 8 when the leg 4 shown in FIG.

 [0036] According to the stand device 1, a plurality of legs that are in a substantially vertical folding non-use state by turning upward and in a substantially horizontal unfolding use state by turning downward. When the leg 4 is not in the folded state, it is designed to stand by the base 2 on the placement part 8 such as the floor surface. This can prevent the camera from interfering with shooting work, etc., and when the leg 4 is not folded, the stand device 1 can be left standing without being tilted sideways. Etc. becomes easy.

 [0037] In addition, when the leg 4 is deployed and used, only the slidable contact portion 40 of the leg 4 comes into contact with the placement portion 8, so that the entire stand device 1 that supports the supported object is removed. It can be easily moved on the mounting portion 8, and photographing work and the like can be easily performed.

[0038] Further, the head 21 of the bolt member 23 is fitted and fixed in the head hole 14 of the base member 11, and the leg member One side 41a of the base end of 41 is slidably contacted to the bottom of the head 21 of the bolt member 23, and the other side 41b of the base 41 is slidable on the inner surface of the other opposing plate 13b. Since the opposing plate portions 13a, 13b do not squeeze inward by tightening the nut member 24, the leg body 4 is not easily affected by the tightening of the nut member 24. The rotation can be performed smoothly.

 [0039] In addition, the leg body 4 can be reliably locked in a substantially horizontal unfolded use state by the lock operation body 5 having a simple configuration, and the lock operation body 5 can be moved slightly by staking it against the bias of the spring 6. Can easily unlock the leg 4.

 [0040] For example, although not shown, the leg body 4 may be configured to be extendable and contractible in the longitudinal direction of the leg body 4.

 [0041] The leg body 4 is not limited to the structure having the slippery contact portion 40 that contacts the placement portion 8 on the lower surface of the distal end portion, and a caster is provided at the distal end of the leg member 41 of the leg body 4. A configuration or the like may be used. Industrial applicability
