  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a perspective view of a wiring box according to a first embodiment of the present invention, FIG. 2 is a plan view of the wiring box as seen from the bottom wall side, and FIG. FIG. 4 is a side view of the wiring box ((a) is a view showing an arrow A in FIG. 2, (b) is an enlarged view of a region B in (a)), and FIG. 4 is a diagram showing a wire rod placed on the bottom wall of the wiring box. FIG. 5 is a perspective view showing a state where the wire is bent and hooked on the hook, FIG. 6 is a plan view showing a state where the wire is bent and hooked on the hook, and FIG. It is a perspective view which shows the state which attached the wiring box with which the wire rod was attached to the reinforcing bar.

  The wiring box 1 is formed, for example, by injection molding or the like of a synthetic resin material, and includes a substantially rectangular bottom wall 2 and a peripheral wall 3 standing on the periphery of the bottom wall 2. It is comprised as a boxed member with a bottom in which the opening part was formed in the other side. Note that a box cover (not shown) (not shown) may be attached to the opening.

  The bottom wall 2 and the peripheral wall 3 are formed with knocks 4 through which wiring, piping, various tubes, etc. can be inserted, and through holes can be formed by removing the blocking portion with a finger or a tool. It is. Further, the bottom wall 2 is provided with a through hole 5 for attaching a metal fitting for fastening the wire.

  The wiring box 1 includes a hook 9 projecting from the surface of the bottom wall 2, so that both ends of the wire 20 approach each other using the wire 20 placed on the surface as a fulcrum on the side wall of the hook 9. The wire 20 can be hooked on the hook 9 by being bent in a straight line.

  In this embodiment, two pairs of hooks 9 are provided for each side along two mutually opposing sides of the rectangular bottom wall 2, and the upper two hooks in FIG. 2 are provided. 9 functions as a hook 9 </ b> A for hooking one wire 20, and the two lower hooks 9 function as a hook 9 </ b> B for hooking another wire 20. Each component of the bottom wall 2 including the hook 9A and the hook 9B is point-symmetric with respect to the center point of the bottom wall surface.

  The hook 9 includes a leg portion 9a erected on the surface of the bottom wall 2 and a claw portion 9b extending in a direction along the surface of the bottom wall 2 on the distal end side of the leg portion 9a. The claw portion 9b extends in a direction away from each other between the two hooks 9 forming a pair. At least a quarter circumference of the side wall 9c of the leg portion 9a is a curved surface, and when the wire 20 is bent along the curved surface, the wire 20 is brought into close contact with the side wall 9c to be stabilized. In addition, this side wall 9c should just become a fulcrum of bending, and does not necessarily need to be a curved surface.

  A recess 8 that accommodates the wire 20 is formed on the surface of the bottom wall 2. The recess 8 extends in a straight line along the side along which the two hooks 9 forming a pair extend. The bottom surface of the recess 8 is a curved surface having a slightly larger curvature radius than the radius of the wire 20. The depth of the recess 8 is shorter than the diameter of the wire 20 so that about half of the wire 20 is exposed from the recess 8.

  Moreover, this recessed part 8 is provided adjacent to the center side of the bottom wall 2 with respect to the two hooks 9 which make a pair, and the wall surface 8b of the bottom wall peripheral side of this recessed part 8 is the longitudinal direction both ends. Are connected to the curved side wall 9 c of the hook 9.

  Further, a shelf 6 is formed as a flat surface parallel to the surface of the bottom wall 2 at both longitudinal ends of the recess 8, and the shelf 6 is connected to the bottom surface of the recess 8.

  Further, the wall surface 8a on the center side of the bottom wall of the recess 8 extends to the region of the shelf 6 along the side along which the two hooks 9 forming a pair extend, and extends between both end edges of the bottom wall 2 facing each other. Is formed.

  Further, two protrusions 10 and 11 are provided on the surface of the bottom wall 2 so as to be adjacent to the wall surface 8a. A claw 10a is formed at the upper end of the protrusion 10, and the wire 20 is fitted by the claw 10a. The protrusion 11 is disposed at an intermediate position between the two hooks 9 forming a pair. The wall surfaces of the protrusions 10 and 11 on the peripheral side of the bottom wall are connected to the wall surface of the recess 8 on the center side of the bottom wall.

  In addition, as the wire 20, for example, an annealed wire that has been cut to a predetermined length, such as an annealed wire, can be used that can be bent and formed relatively easily using a portable tool such as a hand or pliers.

  Next, a procedure for hooking the wire 20 to the wiring box 1 having such a configuration will be described.

  First, as shown in FIG. 4, the linear wire 20 is inserted (placed) into the recess 8 from above the bottom wall 2. At this time, in the present embodiment, the wire 20 is inserted into the recess 8 with the upper half of the wire 20 exposed, but more portions (for example, almost the entire region) may be accommodated.

  The wire 20 inserted into the recess 8 in this way is fitted onto the recess 8, that is, the surface of the bottom wall 2 by the claws 10 a of the two protrusions 10 connected to the peripheral side of the recess 8.

  Next, as shown in FIGS. 5 and 6, the ends of the wire rods 20 approach each other with the side walls 9c of the leg portions 9a of the two hooks 9 forming a pair as a fulcrum (in this embodiment, the bottom of the hook 9 is the bottom). The wire 20 is bent in the direction led out to the wall peripheral side (the direction of the arrow Mb in FIG. 6).

  Here, since the side wall 9c is a surface connected to the wall surface 8b on the peripheral edge side of the bottom wall of the recess 8, the wire 20 can be bent smoothly.

  Furthermore, since the curvature radius of the side wall 9c is set according to the magnitude of the bending radius generated when the wire rod 20 is bent, the bent wire rod 20 is stabilized along the side wall 9c without a gap, and the support strength is increased. be able to.

  In the present embodiment, the end of the side wall 9c on the peripheral side of the bottom wall is set to extend in a direction perpendicular to the peripheral edge. Therefore, in this embodiment, both ends of the wire 20 bent along the side wall 9c (portions outside the position in contact with the side wall 9c) are perpendicular to the periphery of the bottom wall 2 (in FIGS. 5 and 6). Can be derived in parallel to each other.

  Further, the claw portion 9 b of the hook 9 is disposed adjacent to the edge in the width direction of the recess 8 so as not to cover the wire 20 disposed on the recess 8. Therefore, in a substantially straight line state before being bent, the wire 20 can be brought into and out of contact with the bottom wall 2 without being locked by the claw portion 9b, but when bent along the side wall 9c, The claw portion 9b is locked in a direction away from the bottom wall 2.

  In the present embodiment, when the wire 20 is bent, the wall surface 8 a and / or the protrusion 11 on the center side of the bottom wall of the recess 8 functions as a relief suppressing portion that suppresses the relief of the wire 20. That is, the wall surface 8a and / or the protrusion 11 is a portion (a pair) on the side opposite to the point of action of the bending force (in this case, the wire end portion side) with respect to the side wall 9c as the fulcrum fulcrum fb (FIG. 6). The portion between the side walls 9c of the two hooks 9) abuts from the center side of the bottom wall, receives the rotational moment (Mb in FIG. 6) acting on the wire 20 by the bending force, and is opposite to the point of action. The portion is prevented from escaping (turning) to the center side of the bottom wall. Therefore, the worker can bend the wire rod 20 without pressing the wire rod 20 itself as long as the wiring box 1 is pressed or fixed. Since the wire 20 is thin, it is easier to hold the wiring box 1 than to hold it. Therefore, according to this embodiment, by providing the wall surface 8a and / or the protrusion 11 on the center side of the bottom wall of the recess 8 as the escape restraining portion, the bending operation can be performed more easily.

  Furthermore, when the bent wire 20 is bent back into a straight line again, in this embodiment, the wall surface 8a and / or the protrusion 11 on the center side of the bottom wall of the recess 8 functions as a fulcrum fr (FIG. 6) for bending back. The wall surface 8b on the peripheral side of the bottom wall functions as a second escape restraining portion that restrains the escape of the wire 20. That is, the wall surface 8a and / or the protrusion 11 (the portion close to the side wall 9c; however, the position varies depending on the bending state of the wire 20) functions as a fulcrum fr for bending back upon receiving the bending back force. . On the other hand, the wall surface 8b is a portion (the side walls of the two hooks 9 forming a pair) that is opposite to the point of application of the bending return force (in this case, the wire end portion side) with respect to the portion that becomes the fulcrum fulcrum fr. 9c), a rotational moment (Mr in FIG. 6) acting on the wire 20 by the bending return force is received from the bottom wall peripheral side, and the part opposite to the point of action is the bottom wall circumference. Escape (rotate) to the edge side is restricted. Therefore, as long as the operator holds down or fixes the wiring box 1, the operator can bend back the wire 20 without holding down the wire 20 itself. Since the wire 20 is thin, it is easier to hold the wiring box 1 than to hold it. Therefore, according to the present embodiment, by providing the wall surface 8a and / or protrusion 11 on the center side of the bottom wall of the recess 8 and the wall surface 8b on the peripheral side of the bottom wall as the second escape restraint portion, the bending back operation is performed. It can be done more easily.

  As described above, in the present embodiment, the escape suppression portion and the second escape suppression portion can be obtained by an extremely easy method of forming the recess 8 (the wall surfaces 8a and 8b) on the bottom wall 2.

  Furthermore, in the present embodiment, since the protrusion 11 protrudes upward from the upper surface of the bottom wall 2, the protrusion 11 can be prevented from escaping even when the wire 20 is curved to rise from the recess 8. It can function as a part, and the bending work can be facilitated more reliably.

  In addition, in the present embodiment, the shelf 6 (the upper surface thereof) functions as a guide for folding and bending back. That is, at the time of bending and unbending, a wire rod is applied along the top surface of the shelf portion 6 by applying a bending or bending back force to the end portion of the wire rod while being pressed from above the bottom wall 2 to the shelf portion 6 side. 20 can be folded and bent back more easily.

  Then, the two wire rods 20 are hooked to the hooks 9A and 9B in the same manner, and the four wire rod end portions led out from the wiring box 1 as shown in FIG. The wiring box 1 is fastened to the reinforcing bar 21 using the wire 22 by bending it in the direction.

  By the way, in this embodiment, as shown in FIGS. 8-11, the two wire materials 20 fastened substantially in parallel using the fastener 30 can be attached to the bottom wall 2 of the wiring box 1 as it is. It is like that.

  8 and 9 are perspective views of the wiring box when the wire fastened by the fastener is bent and hooked on the hook. In this case, the two wires 20 fastened by the fastener 30 are placed on the bottom wall 2 in the same direction as in FIG. Here, in the present embodiment, the hook 9 is provided in a region outside the two placed wires 20, that is, a region on the peripheral side of the bottom wall, and the interval between the two recesses 8 is set to two wires. It is the same as 20 intervals. Therefore, the two wire rods 20 fastened by the fastener 30 can be placed on the bottom wall 2 without interfering with the hook 9, and each wire rod can be inserted into the recess 8. Therefore, thereafter, each wire 20 is bent and hooked on the hooks 9A and 9B in exactly the same manner as described above, and the wiring box 1 can be supported and fixed to the reinforcing bar 21 in the state shown in FIG. . In this case, the locking claw 31 provided on the fastener 30 is inserted into the through hole 5 of the bottom wall 2 and bent in the housing portion of the wiring box 1 so that the fastener 30 is fixed to the bottom wall 2. Also good.

  On the other hand, FIG. 10 and FIG. 11 are perspective views in the case where the wire is arranged in a direction orthogonal to FIG. 8 and FIG. That is, in this case, the two wires 20 fastened by the fastener 30 are placed on the bottom wall 2 in a direction orthogonal to the case of FIG. Here, in this embodiment, the two hooks 9 forming a pair are arranged in a region sandwiched between two placed wires 20, and the maximum width Wf of the two hooks 9 forming each pair is further increased. The distance Ww between the two wires 20 is set smaller. Therefore, the two wires 20 fastened by the fastener 30 can be placed on the bottom wall 2 without interfering with the hook 9. Then, after the locking claw 31 provided on the fastener 30 is inserted into the through-hole 5 of the bottom wall 2 and bent in the accommodating portion of the wiring box 1, the fastener 30 is attached to the bottom wall 2. 11, the wiring box 1 can be supported and fixed to the reinforcing bar 21. Note that the maximum width Wf of the two hooks 9 that make a pair is set to be approximately the same as or slightly smaller than the interval Ww between the two wire rods 20, and the claw portions 9 b of these four hooks 9 are used by the fastener 30. Two fastened wires 20 may be fitted. In this case, the two wires 20 are temporarily held on the bottom wall 2 so that the subsequent work can be easily performed.

  As described above, according to the present embodiment, since the wire 20 placed on the surface of the bottom wall 2 is bent and hooked on the hook 9, the wire 20 is slightly bent. However, this can be easily used for supporting and fixing. Further, when the wire 20 is folded so as to be hooked, the wall 8a of the recess 8 serves as an escape restraining portion that supports the portion opposite to the point of action of the bending force with respect to the fulcrum fb and suppresses the escape of the wire 20. Since the projection 11 is provided, the wire 20 can be bent more easily and more reliably.

  In addition, according to the present embodiment, when the bent wire 20 is bent back, the wall surface 8a and / or the protrusion 11 of the recess 8 is provided as a bending back support portion that supports the wire as a fulcrum fr for bending back, and the wire rod The wall surface 8b of the concave portion 8 is provided as a second escape suppression portion that supports the portion opposite to the point of action of the bending return force with respect to the fulcrum fr when the 20 is bent back to suppress the escape of the wire rod 20. The wire 20 can be bent back more easily and more reliably.

  Moreover, according to this embodiment, since the claw portion 9b of the hook 9 is provided on the surface of the bottom wall 2 as a wire fitting portion for fitting the placed wire 20, the wire 20 is placed on the surface of the bottom wall 2. The predetermined position can be easily held, and the wire 20 can be bent more easily.

  In addition, according to the present embodiment, when two parallel wires 20 fastened by the fastener 30 are placed on the surface of the bottom wall 2, the two wires are placed on the surface of the hook 9. Since it is provided in a region sandwiched by 20 or a region on the outer surface (periphery side) of the two wire rods 20 on the surface, the parallel two wire rods 20 on the bottom wall 2 without interfering with the hook 9 It can be used for supporting and fixing. In this case, since the two wires 20 can be handled at a time, the supporting and fixing work can be performed more easily and more quickly.

  Furthermore, according to this embodiment, since the maximum width Wf of the two hooks 9 that make a pair is made smaller than the width Ww of the two parallel wire rods 20 fastened by the fasteners 30, the wire rods 20 are formed on the surface of the bottom wall 2. It is possible to more reliably suppress the hook 9 from becoming a hindrance when contacting and separating.
