  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In addition, the shape of each figure referred in the following description is a conceptual diagram or a schematic diagram for explaining a suitable shape dimension, and a dimension ratio etc. do not necessarily correspond with an actual dimension ratio. That is, the present invention is not limited to the dimensional ratio in the drawings.

  FIG. 1 is a perspective view of a connecting fixture 100 according to an embodiment of the present invention. As shown in FIG. 2, the connection fixture 100 has a substantially rectangular shape in plan view, bottom view, and front view. The connecting fixture 100 has a predetermined width and a base portion 101 extending in the longitudinal direction (from the distal end 100a side to the proximal end 100b side), and a connecting portion 102 standing upward from the proximal end 100b side of the base portion 101. And a pressing portion 103 extending from the upper end of the connecting portion 102 toward the tip end 100a so as to face the base portion 101.

  Further, a fixing hole 104 as an attaching means is formed on the base end 100b side of the base 101, and an engaging claw 105 as an attaching means is bent and formed in a hook shape on the distal end 100a side of the base 101. Yes. The attaching means includes a fixing hole 104 and an engaging claw 105. As will be described later, the connecting fixture 100 is attached to the wiring / pipe box via the attaching means.

  A screw hole 106 is formed on the base end 100b side of the pressing portion 103 as a screwing portion into which a screw can be screwed. The screw hole 106 and the fixing hole 104 can be penetrated by one screw. Are in a good positional relationship. Here, when the screw 100 is screwed into the screw hole 106 and the tip 100a side of the connection fixture 100 is opened and closed, the screw is inclined, so that the inclined screw contacts the edge of the fixing hole 104 and the screw Operation may be hindered. Therefore, in the present embodiment, the fixing hole 104 is formed larger than the screw diameter (screw hole 106) to be used so that the screw can be inclined.

  FIG. 2D is a cross-sectional view of the connection fixture 100 taken along the line AA. In this AA cross section, the connecting fixture 100 has a substantially U-shape in side view. On the distal end 100a side, the pressing portion 103 is disposed so as to open at a predetermined angle upward with respect to the base portion 101. This angle can be arbitrarily set as long as the bar can be inserted from the tip 100a side, and is not limited to the angle in the illustrated example. FIG. 2 shows the coupling fixture 100 in the initial state, that is, in the open state. As will be described later, by pulling the pressing portion 103 against the base portion 101 (after placing the bar in the fixed position). The base part 101 and the pressing part 103 are arranged substantially in parallel, and the connecting fixture 100 is deformed into a so-called closed state.

  Further, a first flange portion 107 is erected substantially vertically from both ends in the width direction of the base portion 101, and a first sandwiched notch in an arc shape is formed on the distal end 100 a side of the first flange portion 107. A portion 107a is formed. On the other hand, a second flange portion 108 is erected substantially vertically downward from both end portions in the width direction of the pressing portion 103, and the second flange portion 108 has a semicircular cutout on the front end 100 a side. Two sandwiching portions 108a are formed. As will be described later with reference to FIG. 6B, when the connecting fixture 100 is deformed to the closed state, the second flange portion 108 enters the inside of the first flange portion 107 and is disposed so as to overlap each other in the proximity state. The

  Further, the first clamping part 107a and the second clamping part 108a are configured so that the bar can be clamped between the first clamping part 107a and the second clamping part 108a, and the size corresponds to the diameter of the bar. doing. However, it is not essential in the present invention that the shape of the sandwiching portions 107a and 108a corresponds to the cross-sectional shape of the bar P. That is, the shape, position, and size of the first sandwiching portion and the second sandwiching portion can be arbitrarily changed as long as the bar can be sandwiched, and the arc-shaped or semicircular cut-out shape in the present embodiment. It is not limited to this, and can be cut out into a rectangular shape or the like. Moreover, when not forming a flange part, it is also possible to form in a location other than a flange part, such as curving a part of press part 103 in circular arc shape.

  In the connection fixture 100 of the present embodiment, each component is integrally formed by bending a metal plate. However, the material and the processing method are not limited to the present embodiment, and for example, hard resin, plastic, or the like may be used instead of metal. In the connection fixture, the base portion and the pressing portion may be formed as separate bodies and connected by a connecting portion made of a different material such as rubber or resin.

  FIG. 3 is an exploded perspective view of the bar connecting wiring / piping box 10. The bar connecting wiring / piping box 10 is connected to the wiring / piping box (box main body) 200 by screwing the connecting fixture 100. Configured by attaching with S. The wiring / piping box 200 has a front surface 200c opened and a peripheral wall 201 on the rear surface 200a and the side surface 200b. Here, let the inner side of the surrounding wall 201 be the inner wall 201a, and let the outer side be the outer wall 201b (refer FIG.4 (b)). A plurality of through holes 202 are formed in the peripheral wall 201 of the rear surface 200 a of the wiring / pipe box 200. Then, the engaging claw 105 of the connecting fixture 100 is inserted from the outer wall 201b side into the second through hole 202b so as to engage with the edge thereof, and then the fixing hole 104 and the first through hole drilled in the base 101 are inserted. The connecting fixture 100 is attached to the wiring / piping box 200 by passing the screw S through the hole 202a from the inner wall 201a side and temporarily fixing (screwing) the screw S to the screw hole 106.

  In addition, the 1st and 2nd through-hole in this embodiment only distinguished the through-hole conceptually, and the attachment position of a connection fixing tool is not limited to this embodiment. In other words, the connecting fixture of the present invention can be attached to the peripheral wall of the box via another through hole. Further, in this embodiment, the screw S is screwed into the screw hole 106 that is threaded, but the screwed portion is constituted by the hole and nut that are not threaded, and the screw S is screwed to the nut. It is also possible to attach the connecting fixture to the peripheral wall of the wiring / piping box.

  The wiring / pipe box 200 illustrated in the present embodiment is made of resin and is commercially available as a standard product of the wiring box. However, the wiring / pipe box of the present invention is not limited to the application, configuration, shape, and material shown in the present embodiment. For example, the wiring / piping box may be a box that houses a joint of a water tap and a gas tap, and the material thereof may be metal. Further, the wiring / piping box may not be a standard product, and the number of through holes and the like can be arbitrarily changed. That is, various forms of wiring / piping boxes processed into a desired shape and configuration can be used.

  As shown in FIG. 4A, the bar connecting wiring / pipe box 10 includes a connecting fixture 100, a box body 200, and a screw S. The connecting fixture 100 is positioned at the approximate center of the rear surface 200a of the box body 200. However, the attachment position of the connection fixture 100 is not limited to this, and the connection fixture 100 may be located on the side surface 200b or the like as long as it is the peripheral wall 201 of the wiring / piping box 200, that is, disposed at any position. It is also possible to do.

  FIG. 4B is a plan view of the bar connecting wiring / piping box 10. The base 101 of the connecting fixture 100 is disposed so as to contact the outer wall 201b of the peripheral wall 201 of the box body 200. The screw S is inserted into the through hole 202b from the inner wall 201a side of the box body 200, the head of the screw S abuts against the inner wall 201a, passes through the through hole 202b and the fixing hole 104, and presses 103. And screwed into a screw hole 106 drilled in. At this time, the front end 100a side of the connecting fixture 100 is opened by a predetermined angle so that the bar can enter from the side (open state). As will be described later, when the screw S is further tightened, the screw S advances in the screw hole 106 and rotates so that the pressing portion 103 approaches the base portion 101 with the connecting portion 102 as an axis. That is, by the operation of the screw S, the pressing portion 103 is pulled toward the base portion 101, and the connecting fixture 100 is deformed so as to form a closed state on the distal end 100a side.

  Next, a process of connecting and fixing the bar connecting wiring / piping box 10 and the bolt-shaped bar P will be described with reference to FIG.

  FIG. 5A shows a state before the bar connecting wiring / pipe box 10 is arranged at the position where the bar P is fixed. As shown in FIG. 5 (a), the pressing portion 103 is opened at a predetermined angle on the distal end 100 a side of the connecting fixture 100, and the bar connecting wiring / pipe box 10 is slid in the direction of the arrow X with respect to the bar P. The rod P is moved to enter (insert) between the base portion 101 and the pressing portion 103 of the coupling fixture 100 from the side (tip 100a side). The bar P is substantially perpendicular to the longitudinal direction of the connection fixture 100, and the bar P is positioned between the first clamping part 107a of the base 101 and the second clamping part 108a of the pressing part 103. The bar / connecting wiring / piping box 10 is disposed.

  Next, after arranging the bar connecting wire / pipe box 10 so that the bar P is sandwiched between the first holding part 107a of the base 101 and the second holding part 108a of the pressing part 103, FIG. As shown, the screw S that passes through the through hole 202 of the box body 200 and the fixing hole 104 of the coupling fixture 100 and is screwed into the screw hole 106 is rotated in the tightening direction Y. Then, the screw S advances in the screw hole 106, a force in the closing direction is applied to the pressing portion 103, and the pressing portion 103 rotates in the Z direction so as to approach the base portion 101 with the connecting portion 102 as an axis. And until the 2nd clamping part 108a of the press part 103 contact | abuts to the bar P, the press part 103 is pulled near with respect to the base 101. FIG. At this time, the base portion 101 and the pressing portion 103 of the connection fixture 100 are positioned substantially in parallel, and the connection fixture 100 is deformed into a so-called closed state (see FIG. 5C).

  Further, from the state in which the second clamping portion 108a of the pressing portion 103 is in contact with the bar P (see FIG. 5C), the screw S is tightened with a predetermined torque, whereby the torque is converted into a pressing force. Thus, the second clamping part 108a presses the bar P, and the bar P is clamped between the first clamping part 107a and the second clamping part 108a. At this time, since the semicircular shape of the second sandwiching portion 108a corresponds to the cross-sectional shape of the rod P, the edge of the second sandwiching portion 108a and the rod so that the rod P does not escape to the tip 100a side. The outer surface of P is engaged.

  Therefore, by arranging the bar connecting wiring / pipe box 10 at a predetermined position with respect to the bar P and operating the screw S, the connecting fixture 100 allows the bar P and the peripheral wall 201 of the box body 200 to be connected. Can be connected and fixed.

  FIG. 6A is a front view of a state in which the bar connecting wiring / pipe box 10 and the bar P are connected and fixed. The bar connecting wire / pipe box 10 and the bar P are connected and fixed so that the bar P extends along the width direction of the connecting fixture 100, that is, perpendicular to the longitudinal direction of the connecting fixture 100. ing.

  FIG. 6B is a cross-sectional view taken along the line BB in a state where the bar connecting wiring / pipe box 10 and the bar P are connected and fixed. The connecting fixture 100 is deformed to the closed state, and the second flange portion 108 of the pressing portion 103 enters the inside of the first flange portion 107 of the base portion 101 and is disposed so that the flanges overlap each other in a close state. .

  In this embodiment, the bar P is shown as being installed perpendicular to the ground. However, when the bar P is installed horizontally with respect to the ground, it is installed inclined. In addition, it goes without saying that the connecting fixture and the bar connecting wiring / pipe box of the present invention can be used. Moreover, although the rod P is illustrated as a bolt shape having a thread, the connecting fixture and the rod according to the present invention may be used even if the rod P does not have a thread or a rod having a square cross section or the like. Connection wiring / piping boxes can be used.

  Hereinafter, the operation and effects of the connection fixture 100 and the bar connection wiring / piping box 10 according to an embodiment of the present invention will be described.

  In the open state in which the bar P can be disposed from the distal end 100a side of the pressing portion 103 between the pressing portion 103 of the connection fixture 100 of the present embodiment and the peripheral wall 201 of the wiring / pipe box 200, the base portion 101 is set to the peripheral wall 201. The bar P is disposed between the peripheral wall 201 of the wiring / pipe box 200 and the pressing portion 103 and the pressing portion 103 is pulled toward the peripheral wall 201 side. The bar P and the peripheral wall 201 of the wiring / piping box 200 can be connected and fixed by pressing and clamping. That is, the connecting fixture 100 is attached to the wiring / piping box 200 in advance to form the bar connecting wiring / piping box 10, and the screw S is temporarily fixed, from the opening end on the distal end 100 a side of the connecting fixture 100. Since it is possible to insert the bar material P into the fixed position, in order to connect and fix the wiring / pipe box 200 and the bar material P, without connecting the connecting fixture 100, the wiring / pipe for connecting the bar material is used. It is only necessary to pull the pressing portion 103 of the connection fixture 100 toward the peripheral wall 201 while maintaining only the positional relationship between the box 10 and the bar P.

  In other words, in the conventional type of connection fixture, in order to align the connection fixture, box, and bar with the fixed position, it is necessary to perform connection fixation work such as screw tightening while holding both the connection fixture and the box. On the other hand, when the bar connecting wiring / pipe box 10 including the connecting fixture 100 of the present embodiment is used, only the bar connecting wiring / pipe box 10 and the bar P are used. Since it is only necessary to match the fixing position, it is possible to easily and quickly connect the wiring / piping box 200 and the bar P by gripping only the wiring / piping box 10 for connecting the bar.

  Furthermore, in the conventional connection fixture, when one space before and after the bar is very narrow, the connection fixture and the wiring / piping box are gripped in the space on both sides before and after the bar. For example, when a bar is installed close to a wall surface such as a board or a GL wall, the operator cannot put his hand in the narrow space on the wall surface side. Since it is difficult to grip the wall-side member (either the connection fixture or the wiring / piping box), there is a problem that the connection and fixing work becomes difficult.

  In contrast, in the bar connection wiring / pipe box 10 (or connection fixture 100) of the present embodiment, the operator slides the bar connection wiring / pipe box 10 from the side of the bar P. Since it is only necessary to hold the bar connecting wiring / piping box 10 after being arranged at the bar holding position, work is performed only from one space on the front side or the rear side holding the bar. Can do. Furthermore, by inserting the screw S from the inner wall 201a side of the bar connecting wiring / piping box 10, the bar connecting wiring / piping box 10 is slid and moved behind the bar P (narrow space). It is possible to perform the connecting work only by having a space for making it happen. That is, as long as there is only a small space for placing the pressing portion behind the bar, the operator places the bar connecting wiring / pipe box 10 at a predetermined position, and connects the bar connecting wiring / pipe box. 10 can be tightened from the inner wall 201 side toward the head of the screw S. Therefore, even when the bar is close to the wall surface, the operator does not need to put a hand in the narrow space, and performs the connecting and fixing work quickly and easily from a wider space on the front side or the rear side of the bar. be able to.

  Further, in the bar connecting wiring / pipe box 10 (or the connecting fixture 100) of the present embodiment, the engaging claw 105 of the connecting fixture 100 is the edge of the second through hole 202b of the peripheral wall 201 of the wiring / pipe box 200. The first through hole 202a and the fixing hole 104 of the base 101 are connected by a screw P while being inserted so as to engage with the part. Here, the first through-hole 202a, the fixing hole 104, and the screw hole 106 are in a positional relationship that can be penetrated by one screw S. That is, the base 101 is fixed to the peripheral wall 201 of the wiring / piping box 200 through the fixing hole 104 only by the operation of the screw S, and the pressing portion 103 is pulled toward the peripheral wall 201 side, so that the wiring / piping box 200 and the bar P can be connected and fixed. Further, since the engaging claw 105 is positioned on the tip 100a side of the fixing hole 104, when the screw S that passes through the fixing hole 104 is rotated, the engaging claw 104 and the end edge of the through hole 202a are aligned. Since they are engaged, the base 101 does not rotate around the screw shaft with respect to the peripheral wall 201. That is, the operator can perform the connection fixing work without supporting the connection fixing tool 100.

For example, in FIG. 8A, the connecting fixture 100C can be attached to the wiring / piping box 200C by passing the screw S through the hole 104C and the hole 106C and screwing it into the nut N. By further operating the screw S or the nut N in the attached state, the pressing portion 103C can be pulled toward the base portion 101C. Instead of using the nut N, the pressing portion 103C can be pulled by operating the screw S (not shown) even if the through-hole 202bC is threaded so that the screw S can be screwed together.

(Modification 4)
9A includes a base portion 101D having only a length that can contact the peripheral wall, a pressing portion 103 having a base end 101aD side connected to the base portion 101D via the connection portion 102D, A locking claw 105D as an attaching means formed on the base end 101bD side of the base 101D and a screw hole 106D as a drawing means are provided, but unlike the above-described embodiment, no fixing hole is provided. However, as shown in FIG. 9B, the locking claw 105D is locked to the second through hole 202bD, and the screw S is inserted into the first through hole 202aD and screwed into the screw hole 106D. Fixing tool 100D can be attached to peripheral wall 201D in a non-rotatable manner, and by operating screw S without grasping connecting fixing tool 100D, bar P is pressed and held between pressing portion 103D and peripheral wall 201D. Can do.

(Modification 5)
Instead of forming locking claws on the connecting fixture 100E as in the rod connecting wiring / piping box 10E shown in FIGS. 10A and 10B, at least one protrusion 203E is formed on the peripheral wall 201E. In addition, the connecting fixture 100E can be attached to the peripheral wall 201E of the box body 200E so as not to rotate. That is, as shown in FIG. 10, the connecting fixture 100E is inserted between the two protrusions 203E, and the side surface 103aE (attachment means) of the pressing portion 103E of the connecting fixture 100E is brought into contact with the projection 203E, and the screw The connecting fixture 100E can be attached to the peripheral wall 201E by inserting S into the first through hole 202aE and screwing (temporarily fixing) it into the screw hole 106E. When the screw S is rotated in the forward direction or the reverse direction, the side surface 103aE (attachment means) of the pressing portion 103E is locked to the protrusion 203E located in the rotation direction of the screw S. Accordingly, it is possible to operate the screw S while preventing the connecting fixture 100E from rotating around the screw hole 106E with respect to the peripheral wall 201E, and pull the pressing portion 103E toward the peripheral wall 201E.
