  Next, the mounting screw 25g, which passes through the mounting hole (not shown) provided in the side wall of the box BC, is screwed into the mounting female screw hole 25e of the holding member 25, and the side wall is the standing wall portion 25d of the holding member 25. It fixes to the holding member 25 in the state contact | abutted to. In this state, the holding member 25 to which the box BC is fixed can slide on the support portion 21 of the fixture main body 21.

  Next, when a mounting screw 25 f serving as a fixing member is screwed into the female screw hole 25 c of the holding member 25 and tightened, the tip of the mounting screw 25 f comes into contact with the vertical surface of the support portion 21. When further tightened, a mutual pressing force is generated between the holding member 25 held by the holding portion 25a and the support portion 21, and the holding member 25 becomes difficult to slide with respect to the support portion 21. As a result, the box BC However, it will be fixed to the support part 21 and by extension to the pillar P '.

  However, in this fixture 20, when the box BC is fixed and an opening corresponding to the wall surface on the front surface is provided, and the lateral position of the box BC is finely adjusted, the fixing screw 25f as a fixing member is used. Operation was not possible from this opening and fine adjustment was not possible.

Further, in this case, the box BC is fixed to the standing wall portion 25d of the holding member 25 by a single mounting hole 25e in a cantilever state, and the holding member 25 is about that level due to the structure of the holding portion 25a that allows sliding. The box BC has a relatively large backlash and can be firmly fixed because it is only fixed to such an extent that it is difficult to slide with respect to the support portion 21 by the pressing force of the mounting screw 25f. It was hard to say that there was, and improvement was desired.

FIG. 4 is a front view of another example, and FIG. 4 illustrates a wiring box fixed by the box fixtures of FIGS. 1, 2, and 3, wherein (a) is a side view of the example, and (b) is a front view of (a). (C) is a side view of another example, and (d) is a front view of (c).

  FIG. 5 is a perspective view showing a usage mode when the wiring box shown in FIGS. 1A and 1B is fixed with the box fixing tool shown in FIGS. ) Is a cross-sectional view of the main part, and (c) is a cross-sectional view of the main part after the bending operation of (b).

  The fixture body 1 in FIG. 1, the seat plate 2 in FIGS. 2 (a) and 2 (b), the back plate 3 in FIGS. 2 (c) and 2 (d), and the holding member 4 in FIG. 5 (refer to FIG. 5), the boxes housed in the wall surface of the building are fixed by the holding member 4 through the fixture main body 1 attached to a pillar or the like.

  The fixture main body 1 in FIG. 1 includes a mounting portion 1a that is attached to an existing structure such as a pillar, and a support portion 1b that extends from the mounting portion 1a and supports the box B.

  The attachment portion 1a and the support portion 1b are assumed to be attached to a vertical surface of the structure, with a rectangular flat plate bent at a right angle with a line perpendicular to the longitudinal direction into an L shape. At this time, the plane of the support portion 1b is mounted so that the long dimension is horizontal and the short dimension is vertical, that is, when the mounting state is viewed from the side, it looks like FIG. Is done.

  The attachment portion 1a is provided with attachment holes 1c and 1d for attaching the attachment portion 1a to the structure, and the attachment hole 1d is a long hole.

  The support portion 1b as a whole is formed with a mortar-shaped recess 1g extending in the longitudinal direction at the center in the short dimension direction of a rectangular flat plate, and an intermittent through hole 1h is formed at the deepest center portion. The gap dimension D of the bottom gap of the through long hole 1h corresponds to the hole diameter of the female screw corresponding to the fixing screw (fixing member) 1i used by screwing here.

  The mortar-shaped recess 1g and the long through-hole 1h can be combined with the corresponding fixing screw 1i at any position of the long through-hole 1h. It is called a stop type long hole 1f.

  Further, the through-hole 1h of the screw-locking type long hole 1f is provided intermittently because the support portion 1b is appropriately cut when it is desired to use the support portion 1b in the longitudinal direction. However, the part where one end of the through-hole 1h of the screw-locking type long hole 1f is one-sided is limited to the end, and the other part is not one-sided but screw-locked at an arbitrary position. This is in order to maintain the effect of the screw locking type long hole 1f.

  Both ends in the short dimension direction of the rectangular flat plate are end bent portions 1e bent at a predetermined angle by a predetermined dimension and extend in the longitudinal direction.

  The seat plate 2 in FIGS. 2A and 2B is a square flat plate, and is formed such that four small round projections 2a in the vicinity of the four corners and a large round projection 2d in the center protrude on the same side. Further, a longer elongated hole 2b is formed so as to extend in the vicinity of the two small round protrusions 2a on the upper and lower sides. Further, a pair of shorter long holes 2c are formed so as to be parallel to the long holes 2b and sandwich the central large circular protrusion 2d.

  The anti-projection side of the regular round projection 2d is a small recess 2e that does not penetrate, and the large projection 2d is formed with a large-diameter large recess 2f on the anti-projection side of the large round projection 2d. The protrusion side is penetrated by the through hole 2e.

  The back plate 3 in FIGS. 2C and 2D is a rectangular flat plate, and both diagonals have large rounded chamfers, and there are two elongated holes 3a in series in the longitudinal direction and a screw between them. A hole 3b is formed.

  The holding member 4 in FIGS. 3A, 3B, and 3C includes a flat plate portion 4a on the front surface side, and a holding portion 4b provided on a pair of opposite sides thereof. A pair of upper and lower end curved portions 1e of the support portion 1b of the fixture main body 1 of FIG. 1 are fitted into the rear surface side of the holding portion 4b.

  In the flat plate portion 4a, a bent projection 4c is cut and raised to the right of a position that becomes a center line with respect to the pair of holding portions 4b, and a long attachment hole 4h is formed on the left side.

  The bending protrusion 4c includes a cut 4d, a through hole 4e, a remaining portion 4f, and a leading portion 4g.

  The cut 4d is for cutting and raising the folding protrusion 4c. The through hole 4e is provided at the center of the width of the cut 4d in correspondence with the length of the cut 4d.

  With respect to this notch 4d, the through-hole 4e is a long hole extending from about half the foot length of the notch 4d formed in the U-shaped sideways of the foot length to where it does not reach the foot. It has become.

  The width of the through-hole 4e is equal to the width of the notch 4d, that is, the bending protrusion 4c, and the mechanical strength of the remaining portion 4f is combined with the thickness of the holding member 4 and the material thereof. As shown, by operating the leading portion 4g of the folding protrusion 4c with a human fingertip F, the bending protrusion 4c can be bent at the remaining portion 4f.

  The holding member 4A in FIG. 3D is different from the holding member 4 in that the mounting hole 4i is not a long hole but a round hole whose diameter is the long diameter of the long hole of the mounting hole 4h. .

  The wiring boxes B and BA shown in FIG. 4 are publicly known, include necessary elements, and are provided with mounting holes B1 and BA1 for mounting on an existing structure, and mounting holes B1 and BA1. Bottom walls B2 and BA2 are provided. As can be seen from the figure, the wiring box B is rectangular and the wiring box BA is square.

  A box fixture 5 comprising such a fixture main body 1, seat plate 2, back plate 3 and holding member 4 is used as a set as shown in FIG. 5, and in this example, a channel-like structure which is an existing structure. The case where the wiring box B is fixed to the pillar P is shown.

  First, the seat plate 2 and the back plate 3 are attached to the channel-shaped column P. At this time, the back plate 3 is set on the front side of the seat plate 2 so that the four small round protrusions 2a are fitted between the flanges on the opening side of the channel of the column P, and on the back side of the flange. The flange on the opening side of the channel is sandwiched between the seat plate 2 and the back plate 3.

  In this state, a tightening screw is inserted from the large recess 2f of the seat plate 2, and the screw is screwed into the screw hole 3b of the back plate 3 and tightened. The seat plate 2 is fixed.

  Using the long hole 2b of the seat plate 2, an appropriate position in the direction F1 shown in FIG. 5 (a) is determined with a tightening screw inserted into the mounting hole 1c of the fixing body 1. The main body 1 is fixed to the seat plate 2, that is, the column P.

  In this state, the support part 1b of the fixture main body 1 is configured such that the long dimension direction is the horizontal direction and the short dimension direction is the vertical direction, and the support part 1b is held by the holding part 4b of the holding member 4. When holding, the holding member 4 can slide on the support portion 1b in the direction F2 shown in the figure.

  In this state, if the bent protrusion 4c of the holding member 4 enters the box B in one of the mounting holes B1, the state becomes as shown in FIG. 5B, and the box B does not have to be supported by a person. In this state, the holding member 4 is slidable on the support portion 1b in the direction F2.

  Therefore, the folding protrusion 4c plays a role of temporarily locking the box B so that it does not fall without further folding as will be described below. Improves. From this point, the bending protrusion 4c can also be referred to as a locking protrusion 4c.

  In this case, the leading edge 4g of the locking projection 4c is provided with a bite similar to that provided so that the fish once eaten at the tip of the fishing hook cannot be easily removed, or the outer width is slightly increased. And you may make it fulfill | perform the function which prevents the fall of the box B, without bending the latching protrusion 4c.

  Further, by inserting the tip of a flathead screwdriver into the through hole 4e of the locking projection 4c and partially widening the inner width of the long through hole 4e, the outer width of the locking projection 4c is partially increased. The function of preventing the box B from dropping may be increased.

  Now, when the bending protrusion 4c is bent with a human finger, the bending protrusion 4c has a through-hole 4e that facilitates the bending, so as shown in FIG. The box B is bent along the bottom wall B2 of the box B. In this state, the box B can be slid along the holding member 4 in the direction F2 on the support portion 1b.

  Here, a fixing screw (fixing member) 1i is inserted into the other mounting hole B1 of the wiring box B, and the screw locking type length provided in the support portion 1b of the fixture body 1 through the mounting hole 4h of the holding member 4 The box B can be fixed to the fixture main body 1 and eventually to the pillar P which is a structure by screwing into the through long hole 1h of the hole 1f and tightening.

  That is, the holding member 4 is slidable with respect to the support portion 1b in a state where the box B is held, and the fixing member 1i that passes through the mounting hole B1 formed in the bottom wall B2 from the front opening of the box B. The box B is fixed to the support part 1b by fixing the box B to the support part 1b, and the box B is drawn and tightened with the holding member 4 sandwiched by the support part 1b by the fixing member 1i. Thus, the box B can be firmly fixed to the support portion 1 b of the fixture main body 1.

  In this fixing procedure, the holding member 4 having the folding protrusion 4c in which the through-hole 4e is formed can be easily folded while performing the folding operation with human fingers F while preferably achieving its final purpose. It is possible to demonstrate the effect of good handling and enforcement on site. In particular, when the box B is a normal wiring box, the operation from the opening side has a place restriction, and it is possible to bend even with easy human fingers without using tools such as pliers or pliers. The point that can be done is excellent.

  Further, since the through-hole 4e is provided at the center of the bending protrusion 4c, the strength of the remaining portion 4f is the same on the left and right, and the bending protrusion 4c is the same on the left and right remaining portions 4f. It doesn't bend and it doesn't bend when it leans to one side.

  Further, as will be understood from the above description, the through-hole 4e is formed so as to extend in the longitudinal direction of the folding projection so as to correspond to a portion where the folding projection needs to be bent. It can be bent at a portion, and the length of the mounting hole B1 of the wiring box B (that is, the thickness of the bottom wall of the box B, BA, BB, etc.) can be dealt with in various cases.

  Further, when this through hole is formed from about half the foot length of the cut 4d to a place slightly beyond this foot, the effect of the through hole 4e is that the bent projection 4c portion is not cut and raised. This is also exhibited when the operating force is applied to the leading portion 4g from the state to form the bent protrusion 4c in the state as shown in FIG.

  Therefore, the holding member provided with such a through-hole can be provided not in a state where the bending projection 4c is cut and raised as shown in FIG. Is saved and handling is improved.

  Note that the mounting hole 4h of the holding member 4 is only an escape hole 4h interposed between the mounting hole B1 of the box B and the through long hole 1h of the support portion 1b of the fixture body 1 as can be understood from the above description. Therefore, it is only necessary that the fixing screw (fixing member) 1i can be passed so as not to hinder the fixing.

  Therefore, as in the holding member 4A shown in FIG. 3D, this escape hole (mounting hole) 4i is a round hole whose diameter is the length of the long hole instead of a long hole like the mounting hole 4h. It may be a hole.

6A and 6B show another example of the fixture main body constituting the box fixture of the present invention, in which FIG. 6A is a front view thereof, FIG. 6B is a side view thereof, FIG. 6C is a left side view thereof, d) is a BB cross-sectional view of (a). From here on, the same parts as those already described are denoted by the same reference numerals, and redundant description is omitted.

  Compared to the fixture main body 1 of FIG. 1, the fixture main body 1A is a simple female screw instead of a screw locking type long hole 1f into which a fixing screw 1i that is a fixing member for fixing the box B can be screwed. The difference is that a large number of fixing holes 1j, which are holes, are provided.

  Such a fixing hole 1j cannot fix the box B at an arbitrary position like the through long hole 1h of the screw locking type long hole 1f. However, the disadvantage is that a large number of fixing holes 1j are provided to cover the box B. In other respects, the fixture main body 1A provided with the fixing hole 1j exhibits the same effect as the fixture main body 1 of FIG.

  Further, any one of the holding members 4 and 4A shown in FIG. 3 can be used for the fixture main body 1A. In this case, the same effect as that of the box fixture 10 described above can be obtained as a box fixture. Demonstrate.

  A plurality of fixing holes 1j of the fixing body 1A that are intermittently long while maintaining the screw locking function are screw locking type long holes 1f of the fixing body 1 of FIG. It is.

  FIG. 7 shows another example of the holding member constituting the box fixture of the present invention, wherein (a) is a top view thereof, (b) is a front view thereof, (c) is a side view thereof, and (d). Is a front view of still another example, and (e) is a cross-sectional view of an essential part showing a usage mode of the holding members of (a), (b), and (c).

  7A, 7B and 7C, the holding member 4B has a flat plate portion 4a 'with respect to the holding portion 4b as compared with the holding member 4 in FIGS. 3A, 3B and 3C. Thus, only the portion of the step portion 4j projects to the front surface, and the flat plate portion 4a 'is provided with a fixed female screw hole 4k which is a simple female screw hole instead of the bending projection 4c. Is different.

  The holding member 4C in FIG. 7D is a view of the holding member 4 in FIGS. 3A, 3B, and 3C as compared to the holding member 4B in FIGS. 7A, 7B, and 7C. Like the holding member 4A of 3 (d), the long hole attachment hole 4h is a large round relief hole attachment hole 4i.

  When attaching the box B to the fixture main body 1 with the holding member 4B, first, the holding member 4B is set to be slidable on the support portion 1b of the fixture main body 1.

  Next, as shown in FIG. 7 (e), the fixing screw 4k is inserted into the mounting hole B1 of the box B, screwed into the fixing female screw hole 4k of the holding member 4B, and tightened. In this state, the holding member 4B to which the box B is fixed can slide on the support portion 1b of the fixture main body 1. The subsequent procedure is the same as that described in FIG.

  In this way, the holding member 4B has a point that a separate part called a fixing screw 4k and a tool for tightening the fixing screw 4k are required to lock the box B, but FIG. , (B), (c) exhibits the same effect as the holding member 4.

  Further, the box fixture in which the holding member 4B and the fixture main body 1 are combined as described above exhibits the same effect as the box fixture 5 described in the first embodiment.

  Also, the holding member 4C exhibits the same effect as the holding member 4B, similarly to the holding member 4A for the holding member 4 of FIG.

  In the above, three embodiments have been described, but these are merely examples of the box fixture of the present invention, and the box fixture of the present invention includes different combinations of the above-described elements. Modifications and improvements within an equivalent range are included, and the present invention is not limited to the above-described embodiments.

  In addition, the boxes that can be fixed with the box fixing tool are not limited to the wiring boxes B, BA, and BB exemplified in the present specification, but are accommodated in the wall surface or the like and should be fixed to the existing structure. Moreover, all the boxes provided with the attachment hole in the bottom wall are included.

  The box fixture of the present invention can be used in any industrial field where good handling is required when mounting and fixing boxes and it is desired to fix the boxes firmly.
