In the movable body supporting device 100 or the movable body (box) installation structure of the present embodiment, the supporting body 110 is arranged so as to extend in the vertical direction, and the movable body is supported so as to be slidably movable in the vertical direction. Hereinafter, each component will be described with reference to FIGS. 2 to 8.

First, the support 110 will be described with reference to FIGS. 2 and 3. 2A and 2B are perspective views of the support 110 as viewed from the front and the back. 3A to 3D are a plan view, a front view, a rear view, and a side view of the support 110.

As shown in FIGS. 2 and 3, the support 110 is an elongated plate that is L-shaped in a plan view and extends from the base end to the tip. The support body 110 is located at the base end thereof, and includes a base end portion 111 fixed to the structure, and an extending portion 112 extending from the base end portion 111 toward the tip end in a longitudinal shape. In other words, the support 110 is bent in an L shape, and the short piece-shaped base end portion 111 and the long piece-shaped extended portion 112 are connected at a substantially right angle. In this embodiment, the support 110 is obtained by bending and punching a metal material, but it may be formed of another material such as a synthetic resin.

Two long holes are formed in the base end portion 111 of the support 110, and the support 110 can be fixed to the structure with screws through the long holes. On the other hand, the extended portion 112 of the support 110 is a plate-shaped body having a front surface on the side where the box 130 is arranged and a rear surface on the side where the holder 150 is arranged. Further, an insertion hole 113 for fixing the box 130 with a screw 170 is bored in the extension portion 112 along the longitudinal direction. The insertion hole 113 is formed with a predetermined width in the center of the extension portion 112 in the width direction. As will be described later, the width of the insertion hole 113 is preferably set to be larger than the diameter of the shaft portion of the screw 170 so that the screw 170 to be inserted can slide.

Further, the widthwise end edges of the extended portion 112 are bent toward the rear surface side to form a pair of end edge portions 114. The end edge portion 114 forms a pressed contact portion with which an elastic piece 153 (press contact portion) of the holder 150 described later is pressed. The pressed portion continuously extends in the longitudinal direction. Further, the end edge portion 114 is provided with a plurality of (three in the present embodiment) locking portions 115. The plurality of locking portions 115 define multi-step stop positions (or forced stop positions) of the movable body.

The base 151 is a plate-shaped body having a front surface and a rear surface. More specifically, the base 151 is composed of a horizontal plate extending in the left-right direction at the upper end side thereof and a narrow vertical plate extending in the vertical direction at the center of the horizontal direction. In the assembled form of the movable body support device 100, the left-right direction of the base 151 corresponds to the width direction of the extension 112, and the up-down direction corresponds to the longitudinal direction of the extension 112.

The base portion 151 is configured such that the front surface thereof faces the outer surface of the bottom wall 131 of the box 130, and the extending portion 112 is extendable between the base portion 151 and the outer surface of the bottom wall 131. A pair of side wall portions 155 is provided upright on the front side at both ends in the width direction of the base portion 151. The front end surface of the side wall portion 155 abuts on the bottom wall 131 of the box 130, and forms an accommodation space for slidably accommodating the extending portion 112 between the front surface of the base portion 151 and the outer surface of the bottom wall 131. Functions as a contact. In addition, the pair of side wall portions 155 are respectively formed so as to be located outside both ends in the width direction of the extending portion 112 in the assembled form of the movable body supporting device 100. Then, the base 151 is opened in the up-down direction so as to hold the extended portion 112 slidably between the pair of side wall portions 155 in the plan view shown in FIG. 7C. The distance between the pair of side wall portions 155 is preferably substantially equal to the width of the extension portion 112 in order to accommodate the extension portion 112 without rattling. Further, a sharp cutting edge 151a is formed at the corner of the lower end of the vertical plate of the base 151. The cutting edge 151a is used for cutting the tape that seals the hole of the box 130 at the time of shipping.

The pair of holding portions 152 are integrally formed with the pair of side wall portions 155 and project substantially vertically from the front surface of the base portion 151. The pair of holding portions 152 are configured to cooperate with each other to hold the box 130 with respect to the extending portion 112. In particular, each holding part 152 has a shaft part 152a extending at a predetermined height. The shaft portion 152 a has a length that penetrates the connection hole 133 of the box 130 and a part of the tip end side thereof projects toward the inner surface side of the bottom wall 131. Since the shaft portion 152a is divided by the slit extending in the vertical direction at the center of the diameter, the shaft portion 152a can be elastically deformed so as to reduce the diameter in the width direction. Further, an outer retaining claw 152b as a first retaining portion is formed to project outward in the width direction at an intermediate portion of the shaft portion 152a in the protruding direction, and a second retaining portion is formed at the tip of the shaft portion 152a. An inner retaining claw 152c is formed so as to project inward in the width direction. The outer locking claws 152b and the inner locking claws 152c can be displaced in the radial direction (direction orthogonal to the axial direction) by elastic deformation of the shaft portion 152a in the diameter reducing direction. Then, when the shaft portion 152a is elastically contracted and deformed, the shaft portion 152a can pass through the connection hole 133 of the box 130. On the other hand, in the initial form of the shaft portion 152a, passage of the shaft portion 152a into the connecting hole 133 is restricted. The outer retaining claw 152b is designed for a steel box, and can be retained on the inner surface of the bottom wall 131 of the relatively thin steel box 130. On the other hand, the inner hook claw 152c is designed for a resin box and can be hooked on the inner surface of the bottom wall of a relatively thick resin box (not shown).

The elastic piece 153 is integrally formed with the base 151 as a pressure contact portion. The elastic pieces 153 extend upward so as to form a pair from both end portions in the width direction of the upper end of the base 151. Each elastic piece 153 is composed of a leaf spring extending along the up-down direction (the direction corresponding to the longitudinal direction of the extending portion 112). This leaf spring has a simple structure that does not require adjustment of the pressure contact force. The elastic piece 153 is composed of a base end portion that extends obliquely to the front surface side of the base portion 151 and a tip end portion that bends and extends in a “V” shape from the base end portion, and is provided between the base end portion and the tip end portion. The bent portion projects to the frontmost from the front surface of the base 151. The amount of protrusion of the bent portion is substantially equal to the protruding height of the side wall portion 155. In other words, the front surface of this bent portion is located substantially flush with the front end surface of the side wall portion 155 (parallel to the plane of the base portion 151). Further, the elastic piece 153 is elastically deformable so as to rotate back and forth around the boundary between the upper end edge of the base 151 and the base end portion as an axis. An elastic locking claw 154 protruding to the front surface side is formed at the bent portion of each elastic piece 153. The elastic locking claw 154 functions as a locked portion that is locked in the longitudinal direction by the locking portion 115 of the support body 110.

The pair of elastic locking claws 154 are respectively formed on the pair of elastic pieces 153 so as to be pressed against the edge portions 114 at both ends of the extending portion 112 in the width direction and engageable with the locking portion 115. Each of the elastic locking claws 154 projects toward the front surface side more than the tip surface of the side wall portion 155. Then, the elastic locking claw 154 is configured such that, when the elastic locking claw 154 comes into contact with the end edge portion 114, the elastic piece 153 elastically deforms toward the rear surface side, and the elastic return force acts on the rear surface of the end edge portion 114. ..

The pair of auxiliary elastic pieces 156 are formed so as to extend downward from the side wall portion 155 so as to abut on both end surfaces in the width direction of the extending portion 112. A contact portion 156a extending inward in the width direction is provided at the tip of the auxiliary elastic piece 156. Then, when the extension contact portion 112 is disposed between the pair of side wall portions 155, the auxiliary elastic pieces 156 elastically deform outward in the width direction, and the pair of auxiliary elastic pieces 156 cause the end edge portion 114 of the extension portion 112 to move. It is elastically clamped from the outside in the width direction. The auxiliary elastic piece 156 functions to prevent the base portion 151 and the extension portion 112 from being twisted relative to each other. Further, since the auxiliary elastic piece 156 can be engaged with the locking portion 115 from the outer side in the width direction of the extension contact portion 112, it can also function auxiliary as a pressure contact portion and an elastic locking portion. In the present embodiment, the auxiliary elastic piece 156 sandwiches the extended portion 112 where the locking portion 115 does not exist, but the sandwiching of the auxiliary elastic piece 156 is smaller than the pressure contact force of the pressure contact portion (elastic piece 153). Independently, it is not possible to regulate the falling of the movable body by its own weight. On the other hand, the contact portion 156a of the auxiliary elastic piece 156 enters the locking portion 115 of the extension portion 112, so that a movement restricting force stronger than the pressure contact force is generated.

Further, the base 151 is provided with a screwing portion 157 for screwing the screw 170. The screwing portion 157 is a hole having a size such that the tip of the shaft portion of the screw 170 can be screwed. Further, the screwing portion 157 is formed in the widthwise middle of the base portion 151 so as to communicate with the insertion hole 113 of the extension portion 112 and the screw hole 134 of the box 130 in the assembled form of the movable body supporting device 100. ..

A pair of display windows 158 are formed in the base 151. The display window 158 is formed at a position where the scale portion 118 formed on the rear surface of the extension portion 112 can be exposed to the outside in the assembled form of the movable body support device 100. Specifically, a pair of left and right display windows 158 extend along the width direction of the base 151. Further, the display window 158 is arranged at a position corresponding to the center position of the box 130 (supporting article) in the up-down direction (longitudinal direction) of the base 151 when the holder 150 is attached to the box 130. That is, the user reads the actual distance from the base end portion 111 at the center position of the box 130 by visually observing the scale portion 118 from the rear surface of the extension portion 112 from the outside of the base portion 151 through the display window 158. be able to.

Further, a removable washer 159 is formed on the upper edge of the base 151. The washer 159 is separated from the base 151 at the time of use and is arranged between the head of the screw 170 and the inner surface of the bottom wall 131 of the box 130. The washer 159 is optionally used to adjust the protrusion amount of the tip of the screw 170. For example, if the tip of the screw 170 may interfere with a structure such as a wall on the rear surface side of the extending portion 112 when the box 130 is permanently fixed to the support 110 with the screw 170, the screw 170 may be inserted through the washer 159. The interference with the structure can be avoided.

Next, based on the description of each component, a movable body in which the holder 150 is mounted in the box 130 will be described with reference to FIGS. 9 to 11. 9A and 9B are perspective views of the movable body viewed from the front and the back. 7A to 7E are a plan view, a front view, a bottom view, a rear view and a side view of the movable body. 8A and 8B are cross-sectional views of the holder 150 taken along lines DD and EE.

The movable body according to the embodiment of the present invention includes a box 130 which is also represented as a supporting article or a movable body, and a holder 150 attached to the box 130. That is, when the holder 150 is attached to the box 130, a movable body that slides on the support 110 is configured.

As shown in FIGS. 9 to 11, the holder 150 is connected to the box 130 from the outer surface of the bottom wall 131 of the box 130 in a retaining state. The holder 150 is connected to the bottom wall 131 via the holder 152, and the base 151 extends so as to face the outer surface of the bottom wall 131. The base portion 151 is arranged so as to be separated from the outer surface of the bottom wall 131, and between the front surface of the base portion 151 and the outer surface of the bottom wall 131, the extension portion 112 of the support body 110 is slidably inserted vertically (extension portion 112). A storage space opened in the longitudinal direction) is provided.

More specifically, as shown in FIG. 11, the shaft portions 152a of the pair of holding portions 152 respectively penetrate the pair of connecting holes 133 of the bottom wall 131, and the outer hooks 152b are arranged on the inner surface side of the bottom wall 131. Has been done. Each of the shaft portions 152a is in a state of being elastically restored at least partially in the radial direction. The pair of outer hooks 152b are arranged so as to be hooked on the periphery of the connecting hole 133 on the inner surface of the bottom wall 131. In addition, the pair of side wall portions 155 are arranged so that the tip surfaces thereof almost come into contact with the outer surface of the bottom wall 131. That is, the outer retaining claws 152b and the side wall portions 155 cooperatively regulate the axial movement of the shaft portion 152a with respect to the box 130 of the holder 150, and the accommodation space for the extension portion 112 is provided on the front side of the base portion 151. I am maintaining.

Further, the elastic piece 153 (elastic locking claw 154) is in contact with the outer surface of the bottom wall 131 of the box 130 (see FIG. 11B). At this time, the elastic piece 153 is elastically deformed so as to tilt toward the outer surface side of the base 151. In particular, the elastic piece 153 is elastically tilted by the amount of protrusion of the elastic locking claw 154. The elastic piece 153 presses the outer surface of the bottom wall 131 by its elastic restoring force, and accordingly, the base 151 is urged in a direction of separating from the outer surface of the bottom wall 131. As a result, the outer retaining claws 152b of the holding portion 152 engage with the inner surface of the bottom wall 131 in a biased state, and rattling between the holder 150 and the box 130 is effectively suppressed. The center position of the box 130 is sandwiched between the elastic locking claw 154 and the contact portion 156a of the auxiliary elastic piece 156 in the vertical direction. As a result, in the movable body support device 100, the elastic locking portions 154 and 156a that are closer to the locking portion 115 are locked to the locking portion 115 of the extended portion 112, and the positional deviation can be reduced.

Further, the threaded portion 157 of the holder 150 is arranged so as to communicate with the screw hole 134 of the box 130. Accordingly, the screw 170 can be inserted from the inner surface side of the box 130 and screwed into the screwing portion 157. Further, the display window 158 of the holder 150 is arranged so as to match the center position of the box 130 in the vertical direction. Accordingly, it is possible to visually check the scale portion 118 on the rear surface of the extension portion 112 through the display window 158 and confirm the center position on the extension portion 112 of the box 130. In particular, since the base 151 of the holder 150 is plate-shaped, it is easier to visually recognize the scale through the display window 158 than by visually observing through the bottom wall 131 located at the back of the box 130.

In order to construct the movable body of the present embodiment, the front surface of the base 151 of the holder 150 faces the outer surface of the bottom wall 131 of the box 130, and the shaft portions 152a of the pair of holding portions 152 are inserted into the pair of connecting holes 133. To do. Since the tip of the shaft portion 152a is tapered, as the shaft portion 152a is pushed into the connecting hole 133, the shaft portion 152a elastically reduces its diameter. The holder 150 is pressed against the outer surface of the box 130 until the inner hooks 152c and the outer hooks 152b sequentially pass through the connecting hole 133. When the outer retaining claw 152b moves to the inner surface side of the box 130, the shaft portion 152a elastically returns to expand and deform. As a result, the outer retaining claws 152b are arranged so as to be retained by the periphery of the communication hole 133 on the inner surface of the bottom wall 131. A movable body can be constructed by the above steps. The shaft portion 152a is contracted and deformed from the opening side of the box 130 and pushed into the outer surface side of the bottom wall 131 to allow the hooks 152b, c to pass through the connecting hole 133, and the holder 150 to be removed from the box 130. Can be released.

Next, the movable body support device 100 and the installation structure thereof according to the embodiment of the present invention will be described. 12A and 12B are perspective views of the movable body support device 100 as viewed from the front and the back. 13A and 13B are a plan view and a rear view of the movable body support device 100. 14A and 14B are a plan view and a side view of the movable body support device 100. 15 to 18 are cross-sectional views of the movable body support device 100 taken along line FF, GG, HH, and II.

The movable body support device 100 is configured to support the movable body at a predetermined position of the support body 110. In the embodiment described below, a box installation structure is constructed by the movable body support device 100 by fixing the base end 111 to the structure so that the longitudinal direction of the extension 112 of the support 110 is vertical. To be done. However, it goes without saying that the movable body supporting device 100 may be used by arranging the extending portion 112 in the horizontal direction or the inclined direction.

As shown in FIGS. 12 to 14, the movable body support device 100 has a housing space in which the extending portion 112 of the support body 110 is formed between the front surface of the base 151 of the holder 150 and the outer surface of the box 130 in the longitudinal direction. It is configured to penetrate. In the movable body support device 100, the movable body is supported by the support body 110 so as to be slidably movable along the extending portion 112 so as to be close to and away from the base end portion 111.

In the movable body supporting device 100, as shown in FIG. 15, the shaft portion of the screw 170 penetrates the screw hole 134 of the box 130 and the insertion hole 113 of the support body 110, and is screwed to the screwing portion 157 of the holder 150. ing. Here, the movable body is temporarily fixed to the support body 110 with the screw 170 loosened. In this temporary fixing mode, the movable body can be held at a predetermined position of the extending portion 112 in a state in which free movement along the extending portion 112 is restricted by the pressure contact of the elastic piece 153. Here, the free movement means that the movable body resists the support body 110 due to, for example, a free fall due to its own weight, an unintentional (or non-forced) addition of force due to rattling, loosening of the screw 170, or the like. Means to move without. On the other hand, by forcibly (or artificially) applying a force to the movable body, the movable body can be forcibly slid along the extending portion 112 to adjust the position of the movable body. .. At this time, the shaft portion of the screw 170 moves in the insertion hole 113 extending in the longitudinal direction, so that the linear movement of the movable body is smoothly guided. Then, after the position of the movable body is adjusted in the longitudinal direction, the movable body can be permanently fixed to the predetermined position of the extension portion 112 of the support body 110 so as not to be slidable by fastening the screw 170. Since the connecting hole 133 and the screw hole 134 are arranged on the same circumference, the movable body can be stably and permanently fixed to the support body 110.

More specifically, as shown in the cross section shown in FIG. 17, the extended portion 112 of the support 110 is provided between the pair of holding portions 152 (side wall portions 155) of the holder 150 and the outer surface of the bottom wall 131 of the box 130. It is sandwiched and held by the front surface of the base 151. The holding portion 152 and the side wall portion 155 are positioned so as to slidably contact the end edge portion 114 of the extending portion 112 from the width direction outer side. Further, the abutting portions 156a of the pair of auxiliary elastic pieces 156 elastically abut on the widthwise end faces of the extension portions 112. This prevents the holder 150 from being twisted with respect to the extending portion 112. Since the accommodation space is opened in the longitudinal direction (vertical direction) of the extension 112 and is closed in the width direction, only the longitudinal sliding movement of the movable body on the extension 112 is allowed. To be done.

As shown in FIGS. 16 and 18, the front surfaces of the pair of elastic pieces 153 are in contact with the rear surfaces of the extending portions 112, and the front surfaces of the extending portions 112 are in contact with the outer surfaces of the bottom wall 131. The elastic piece 153 is elastically deformed toward the rear surface side of the base 151, and is pressed against the rear surface of the extension portion 112 by the elastic restoring force. More specifically, as shown in FIG. 18, the front surface of the elastic locking claw 154 is in pressure contact with the rear surface of the end edge portion 114. By inserting the extension 112 into the accommodation space of the movable body, the front surface of the elastic piece 153 is separated from the outer surface of the bottom wall 131, and the elastic return force is increased from the initial value. Further, since the elastic piece 153 is in pressure contact with the surface of the extension portion 112 opposite to the surface facing the box 130 side, it does not interfere with the sliding movement of the box 130. Then, the extended portion 112 is pinched by the outer surface of the bottom wall 131 and the elastic piece 153, so that frictional resistance when the movable body slides is generated or increased. Due to this frictional force, the movable body is held at a predetermined position of the extension portion 112 in a state where its free movement is restricted. In the present embodiment, the elastic piece 153 is a pressure contact member that regulates the falling of the movable body under its own weight so that the frictional force resists the own weight of the box 130 and the holder 150 when the longitudinal direction of the extended portion 112 is vertical. It is pressed against the extension portion 112 by force. The holding or temporary fixing of the movable body by the press-contact means is constantly exerted on the extending portion 112 of the support body 110 continuously in the longitudinal direction. By operating the movable body with a force of an appropriate strength exceeding the frictional force by the pressure contact means, the movable body is forcibly slid steplessly while maintaining the pressure contact state, and precise position adjustment of the movable body is performed. It becomes possible to do. Accordingly, the user can operate the movable body without dropping it and easily adjust the position of the movable body. It is also possible to easily separate the movable body from the support body 110 by sliding the movable body over the tip of the extending portion 112. Alternatively, when the movable body is supported by the support body 110, the holder 150 and the box 130 are separated so that the movable body can be moved from the support body 110 without sliding the movable body to the tip of the extended portion 112 of the support body 110. The body can be easily removed.

Further, in the movable body support device 100, the locking portion 115 of the support body 110 locks the elastic locking claws 154 (elastic locking portion, locked portion) of the holder 150 to prevent the movable body from sliding. It is configured to regulate. The locking means functions to stop the movable body stepwise by the plurality of locking portions 115 when the movable body unexpectedly slides against the stepless regulation by pressure contact. In the present embodiment, it is determined that the box 130 is permanently fixed (immovably) at the position where the locking portion 115 does not lock the holder 150. That is, the locking portion 115 is not used for aligning the movable body, but is intended to limit excessive movement of the movable body. Preferably, at least one locking portion 115 is arranged below the holder 150 (elastic locking claw 154) in the assumed main fixing position. However, in the present invention, the locking portion may be used for alignment depending on the attachment position on the extension portion. Hereinafter, the locking means will be described in more detail with reference to FIGS. 19 to 21. 19A and 19B are a rear view and a side view showing a state in which the movable body unexpectedly descends and the movable body is locked by the locking portion 115 of the support body 110 in the movable body support device 100. It is a figure. 20 and 21 are sectional views taken along the lines JJ and KK.

As shown in FIGS. 20 and 21, in the state where the movable body is locked by the locking means, the pair of elastic locking claws 154 of the holder 150 are concavely cut at both edges in the width direction of the extending portion 112. It is elastically engaged with the locked portion 115. At this time, the elastic piece 153 is elastically deformed toward the rear surface side of the base 111, and the elastic locking claw 154 is biased in the locking portion 115 by the elastic return force. Then, the pair of elastic locking claws 154 directly contact the notched end surfaces of the locking portions 115 in the longitudinal direction, so that the movable body is stopped in the longitudinal direction. The engagement of the elastic locking claw 154 and the locking portion 115 is released by forcing the movable body along the extending portion 112 with a force that further elastically deforms the elastic locking claw 154 to the rear surface side of the base 151. This can be done by sliding. The strength of the force required to elastically release this restriction is significantly greater than the strength required to forcefully slide the movable body steplessly under the frictional force of the pressure contact means.

In addition, in the movable body (box) installation structure by the movable body support device 100, when the extending portion 112 is arranged along the vertical direction and the movable body is installed at a predetermined attachment position, the locking portion 115. It is preferable that at least one of them is located vertically below the elastic locking claw 154. In general, the movable body is more likely to move downward than in the vertical direction due to its own weight. Therefore, since the locking portion 115 is located below the elastic locking claw 154, it is possible to effectively restrict the movable body from falling over the locking portion 115. Further, the contact portion 156a of the auxiliary elastic piece 156 is positioned vertically below the elastic locking claw 154. In other words, since the elastic locking claws 154 and the auxiliary elastic pieces 156 that can be engaged with the locking portion 115 are arranged in the upper and lower two stages, even if one of them is disengaged, they are locked next, so that they can move more reliably. It is possible to regulate the free fall of the body.

Further, in the movable body supporting device 100 and the movable body installation structure of the present embodiment, as shown in FIG. 19, the opening of the box 130 at the attachment position and the box 130 is locked to at least one of the locking portions 115. The position of the locking portion 115 and the size of the box 130 are designed so that the opening of the box 130 in the closed position partially overlaps in the vertical direction. Generally, in the movable body installation structure, a wall material is erected on the front surface of the box 130, and the box 130 is installed so as to face the wall surface through a through hole formed in the wall material. In the movable body supporting device 100 of the present embodiment, when the position of the locking portion 115 and the size of the box 130 are set as described above, the box 130 is accidentally dropped and locked by the locking portion 115. Moreover, it becomes easy for the user to return the box 130 above the locking portion 115 from the wall surface through the through hole.

Further, the movable body supporting device 100 of the present embodiment adjusts the position of the movable body while visually confirming the position of the movable body by at least one of the display section 117 and the scale section 118 formed on the front and rear surfaces of the extending section 112. You can The display unit 117 displays the distance between the predetermined reference point and the center position of the box 130 in a format that is visible and readable from the front side. In the present embodiment, as shown in FIG. 22A, the movable body is aligned so that the outer peripheral edge (outline) of the box 130 matches the uppermost steel box display 117a. That is, the separation distance from the reference point of the center position of the box 130 is readablely displayed on the boundary with the longitudinal edge of the box 130 on the display unit 117. In the example, the top steel box display 117a indicates that the center position of the box 130 is 300 mm away from the base end 111. On the other hand, as shown in FIG. 22B, by visually observing the scale portion 118 arranged at a position corresponding to the center position of the box 130 through the display window 157 formed in the holder 150, the box The separation distance of the center position of 130 from the reference point can be grasped. In the example, it is displayed via the display window 157 that the center position of the box 130 is 300 mm away from the reference point. That is, in the movable body supporting device 100 of the present embodiment, it is possible to visually grasp the position of the movable body from both the front surface and the rear surface of the support body 110 and adjust the position of the movable body to a predetermined attachment position. Is. In the present embodiment, numbers that can be easily set are attached, but even if the target distance is other than that, the box 130 can be roughly arranged close to it.

Next, a method of constructing a movable body installation structure by the movable body supporting device 100 will be described. First, as described above, the holder 150 is attached to the box 130 to assemble the movable body. Further, the base end portion 111 of the support 110 is fixed to the structure behind the wall with screws or the like. In the present embodiment, the support 110 is installed so that the extending portion 112 extends in the vertical direction. At this time, it is preferable that the wall material is not yet erected both before and after the space behind the wall. Next, the movable body is moved vertically closer to the extended portion 112 so that the tip of the extended portion 112 of the support 110 is inserted into the accommodation space between the box 130 and the holder 150 of the movable body. When the extending portion 112 is arranged in the accommodation space, the elastic piece 153 (elastic locking claw 154) is pressed against the rear surface of the extending portion 112, and the free movement of the movable body is restricted. That is, even if the user releases his/her hand from the box 130, the movable body is maintained in the extension portion 112 without free fall.

Then, in order to move the movable body to a predetermined attachment position, the movable body is forcibly slid by a force exceeding the frictional force of the pressure contact means. The predetermined attachment position is appropriately determined by the relative distance between the reference point (the base end 111, the specific point of the structure or the extension 112) and the center position of the box 130. When it is necessary to ride over the locking portion 115 and perform alignment, a stronger force is applied to release the locking and the movable body is forcibly slid. In addition, when working from the front side (wall surface) of the box 130, the separation distance of the center position is read from the display unit 117 displayed on the front surface of the extension unit 112, and the outer peripheral edge of the upper side of the box 130 is displayed on the display unit 117. The movable body is moved on the extending portion 112 so as to be aligned with the selected steel box display 117a, and alignment is performed. On the other hand, when working from the rear surface side of the box 130, the movable body is moved on the extension portion 112 based on the notation of the scale portion 118 that can be read from the display window 157 on the rear surface side of the base portion 151 to perform the alignment. Before and after the alignment, the screw 170 is inserted into the screw hole 134 from the front side of the box 130, and screwed into the screwing portion 156 through the insertion hole 113 to temporarily fix the movable body to the extending portion 112. If necessary, the movable body position can be finely adjusted along the longitudinal direction while the screw 170 is loose. After the movable body is arranged at the predetermined attachment position, the movable body can be permanently fixed to the support body 110 by tightening the screw 170. Even without the screw 170, it is possible to perform precise position adjustment under the pressure contact force of the pressure contact portion. In this case, after adjusting the position of the movable body, the screw 170 is used for main fixing.

In addition, the wall material is erected both in front of and behind the movable body supporting device 100 to close the space behind the wall. Then, the position of the box 130 is detected from the wall surface side so that the opening of the box 130 is exposed to the front wall surface, and a through hole having a predetermined diameter is formed in the wall material by a hole saw or the like. The position of the box 130 can be detected by a conventional technique using a magnet or the like. If the center of the through hole is aligned with the center position of the box 130 after the through hole is formed, the movable body installation structure is completed.

However, in many cases, the movable body moves due to vibration when the wall material is erected, and the center position of the box 130 and the center of the through hole are displaced from each other. In such a case, it is necessary to operate to loosen the screw 170 from the wall surface and move the movable body in the axial direction to adjust the position. In the movable body installation structure according to the present embodiment, even if the screw 170 is loosened, the movable body is restrained from dropping by its own weight by the pressure contact means, and is held in place. Further, even if the user applies an excessive vertical downward force to the movable body and the movable body slides down the extended portion 112, the locking portion 115 locks the holder 150, and the movable body moves. It is possible to prevent movement to an unintended area (for example, a position where the box 130 disappears from the through hole). Then, the user operates the movable body while loosening the screw 170 through the through hole so as to align the center position of the box 130 with the center of the through hole, and then fastens the screw 170. By doing so, the movable body installation structure is completed. Wiring equipment or the like may be attached to the box 130 from the front side of the wall. The arrangement method of the present invention is not limited to the order of the steps described above, and it is possible to replace each other as necessary or omit unnecessary steps.

Hereinafter, the operation and effect of the movable body support device 100 according to the embodiment of the present invention will be described.

According to the movable body supporting device 100 of the present embodiment, the elastic locking claw 154 provided on the movable body is engaged with the locking portion 115 provided on the extending portion 112 of the supporting body 110. The relative movement of the elastic locking claw 154 beyond the locking portion 115 in the longitudinal direction is restricted. That is, since the movable body is locked at the predetermined stop position on the extended portion 112 by the locking portion 115, the free movement of the movable body can be limited within the predetermined range on the extended portion 112. .. As a result, it is possible to prevent the movable body from reaching an unexpected area such as the tip portion of the extended portion 112 due to unintended free movement (for example, free fall). Further, since the locking portion 115 and the elastic locking claw 154 elastically engage in the longitudinal direction, the engagement can be selectively released by the forcibly sliding movement of the movable body. That is, the movable body support device 100 of the present embodiment enables the movable body to be slid and supported at a desired position of the extending portion while effectively restricting the unintentional free movement of the movable body.

Further, the movable body supporting device 100 of this embodiment employs a combination of the pressure contacting means continuously exerted along the longitudinal direction of the supporting body 110 and the discontinuously exerting locking means. The double prevention of unintended movement of the movable body (including falling by its own weight). Further, the predetermined attachment position by the main fixing of the movable body is not the position where the locking portion 115 locks the holder 150, but the region (specifically, elasticity) where the pressure contact means other than the locking portion 115 acts. The locking claw 154 is set above the locking portion 115 in the longitudinal direction). That is, in the movable body supporting device 100, between the adjacent locking portions 115, a stepless movement region where fine adjustment of the fine movable body position is easy under the frictional resistance by the pressure contact means is formed continuously in the longitudinal direction. To be done. In contrast to the pressure contact means, each locking part 115 allows a stepped slide of the movable body, which can be unlocked by applying a relatively stronger force than a stepless movement. As a result, excessive movement of the movable body (to an unintended area) can be properly regulated in stages.
