  According to the mounting body according to the present invention, the deformation restricting portion provided opposite to both side surfaces of the elastic engagement piece prevents the elastic engagement piece from being deformed in the lateral direction and makes it difficult to remove the screw. Can do.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  1 to 9 show an embodiment of the present invention. Reference numeral 1 in the figure denotes a building wall. Reference numeral 2 denotes a wiring device such as an outlet or a switch as an attachment. Reference numeral 3 denotes a holding panel as a holding material for holding the wiring device 2 as the attached object. 4 is a screw as a fixing tool. The screw shaft portion 4a of the screw 4 has a screw forming portion 4b in which a male screw is formed, and a smooth surface portion 4c having a smooth peripheral surface located on the tip side of the screw forming portion 4b. Reference numeral 5 denotes a box as an attachment, particularly a wiring box, to which the wiring device 2 as an attachment is attached using screws 4. Reference numeral 10 denotes a box device as an attachment device, which includes a wiring box 5 as the attachment body and the screws 4.

  Here, the holding panel 3 is formed in a frame shape, and the wiring device 2 is attached in the frame. The holding panel 3 is formed with holes 3a through which the screws 4 are inserted on each side thereof, for example, the upper and lower sides.

  The wiring box 5 as the attachment body includes a box body 6 as the attachment body and a screw fixing member 7 made of a plate material for fixing the screws 4. The box body 6 includes a peripheral wall 6c surrounding the internal space 6b so as to form an internal space 6b having an open portion 6a on one side, and a boss portion 6d positioned on the inner surface side of the peripheral wall 6c. The boss portion 6d has an insertion hole 6e into which the screw shaft portion 4a of the screw 4 is inserted from the open portion 6a side, an accommodation space 6f that communicates with the insertion hole 6e and accommodates the screw fixing member 7. Is provided. The insertion hole 6e includes a first screw restriction hole 6h provided in front of the housing space 6f for restricting the screw shaft portion 4a to be positioned substantially on the center line 6g of the insertion hole 6e, It has the 2nd screw control hole 6i provided in the back | inner side (rear side) rather than the accommodation space 6f. In the illustrated embodiment, the first and second screw restricting holes 6h, 6i are formed in a circular cross section in which the screw shaft portion 4a (specifically, the screw forming portion 4b) just fits. The second screw restricting hole 6i is formed when the elastic engagement piece 7b (described later) of the screw fixing member 7 is engaged with a male screw located at the tip of the screw forming portion 4b of the screw shaft portion 4a. The smooth surface portion 4c is positioned so as to fit into the second screw restricting hole 6i (see FIG. 7). The smooth surface portion 4c appears with the raw material when the screw shaft portion 4a is formed by rolling, and has an outer diameter slightly smaller than the outer diameter of the screw forming portion 4b.

  The screw fixing member 7 includes an elastic engagement piece 7b (in the illustrated embodiment, one elastic engagement piece 7b). The elastic engagement piece 7b is inserted so that the tip of the elastic engagement piece 7b is engaged with the male screw of the screw shaft portion 4a inserted into the insertion hole 6e to prevent the screw shaft portion 4a from coming off. It extends toward the hole 6e side. Therefore, the wiring box 5 is opposed to the lateral side surfaces 7e and 7e on the lateral side perpendicular to the extending direction of the elastic engagement piece 7b engaged with the male screw of the screw shaft portion 4a. Deformation restricting portions 8 and 8 for restricting the deformation of the elastic engagement piece 7b in the lateral direction are provided (see FIGS. 3 and 6).

  Here, for the insertion of the screw shaft portion 4a into the insertion hole 6e, the elastic engagement piece 7b is inclined in the insertion direction P of the screw shaft portion 4a, or the inclination in the insertion direction P is increased. Thus, in the illustrated embodiment, the screw shaft portion 4a is allowed to move in the insertion direction P by being elastically deformed (so that the inclination in the insertion direction P is increased). On the other hand, when the screw shaft portion 4a is removed from the insertion hole 6e, the elastic engagement piece 7b engaged with the screw shaft portion 4a moves in the removal direction Q of the screw shaft portion 4a in the insertion direction P. By pressing the screw shaft portion 4a in an attempt to be elastically deformed so that the inclination is reduced, it is difficult to elastically deform the elastic engagement piece 7b in the pulling direction Q, and the screw shaft portion 4a has the pulling direction Q. Stop moving to.

  Specifically, the box body 6 is made of, for example, a synthetic resin, and has a box shape with the opening 6a on the front side, for example, a rectangular parallelepiped shape. Therefore, the boss portion 6d is formed on each of the upper and lower sides of the box body 6 so as to protrude from the peripheral wall 6c toward the internal space 6b. And the insertion hole 6e is formed in this boss | hub part 6d toward the back from the front side (namely, the said opening part 6a side) of the box main body 6. FIG. Further, the housing space 6f is formed in the boss portion 6d so as to extend in a direction intersecting the insertion hole 6e and to open in the intersecting direction. Specifically, the accommodation space 6f extends in a direction orthogonal to the insertion hole 6e, and opens in the orthogonal direction (in the illustrated embodiment, opens in the peripheral wall 6c of the box body 6). As shown in FIG. 3, the housing space 6 f includes a front wide portion 6 j and a rear narrow portion 6 k. And the wall surface which forms the accommodation space 6f (the narrow part 6k in the illustrated embodiment) is the deformation restricting parts 8 and 8 (see FIGS. 3 and 6). Specifically, the deformation restricting portions 8 and 8 are made of a wall surface that forms the width of the accommodating space 6f (the narrow portion 6k in the illustrated embodiment), and between the deformation restricting portions 8 and 8 made of the wall surface, The elastic engagement piece 7b just fits. That is, the width of the accommodation space 6f (the narrow portion 6k in the illustrated embodiment) is substantially the same as the width of the elastic engagement piece 7b.

  In the housing space 6f, a pair of pressing ribs 6m and 6m for partially pressing a plate surface of a body portion 7a described later of the screw fixing member 7 sandwich the screw shaft portion 4a inserted into the insertion hole 6e. And is formed so as to extend in the extending direction of the accommodation space 6f (see FIGS. 2 to 4). Specifically, the presser rib 6m is provided in the wide portion 6j, and is formed to protrude from the top surface of the wide portion 6j located on the side opposite to the narrow portion 6k.

  The insertion hole 6e faces the elastic engagement piece 7b of the screw fixing member 7 so that the screw shaft portion 4a extends in the direction opposite to the side where the elastic engagement piece 7b is located and the elastic engagement piece 7b extends. A screw restricting portion 6n is provided for restricting movement in the lateral direction perpendicular to the installation direction (see FIGS. 2 and 6). Specifically, the screw restricting portion 6n is provided between the first screw restricting hole 6h and the second screw restricting hole 6i, and is connected to the deformation restricting portion 8 on the back side of the narrow portion 6k. It consists of a semicircular arc wall.

  The screw fixing member 7 is made of a plate material having a spring property, for example, a metal plate such as a steel plate or a copper alloy plate, and includes a main body portion 7a and the elastic engagement piece 7b extending from the main body portion 7a. The main body portion 7a is formed in a frame shape, and the elastic engagement piece 7b and a hole 7c through which the screw shaft portion 4a is inserted are arranged in the frame. The elastic engagement piece 7b is bent from the side opposite to the hole 7c on the inner side of the main body portion 7a, and is directed toward the hole 7c, that is, the insertion hole 6e, and slightly tilted in the insertion direction P of the screw shaft portion 4a. It is extended. And the arc-shaped recessed part 7d is formed in the front-end | tip of the elastic engagement piece 7b so that the outer periphery of the screw shaft part 4a inserted in the insertion hole 6e may be followed. That is, the concave portion 7d is adapted to engage with the male screw of the screw shaft portion 4a inserted into the insertion hole 6e. The screw fixing member 7 is accommodated in the accommodating space 6f such that the elastic engagement piece 7b is closer to the base end side of the boss portion 6d than the hole 7c, that is, the insertion hole 6e. The screw fixing member 7 has its main body portion 7a accommodated and held in the wide portion 6j in the accommodation space 6f, and the elastic engagement piece 7b is accommodated in the narrow portion 6k in the accommodation space 6f so as to be elastically deformable. (See FIG. 3).

  Next, the operation and effect of the wiring box 5 and the box device 10 having the above configuration will be described. The wiring box 5 is previously attached to a column or the like on the back side of the wall 1 with a fixing tool such as a wood screw. Therefore, in order to attach the wiring device 2 to the wiring box 5, a holding panel in which the wiring device 2 is attached to the surface of the wall 1 in the wall hole 1 a portion opened in the wall 1 corresponding to the wiring box 5. 3 is assigned. Thereafter, the screw 4 (specifically, the screw shaft portion 4a) is passed through the hole 3a of the holding panel 3, and the insertion hole 6e provided in the boss portion 6d of the wiring box 5 is inserted into the front side (that is, the opening portion 6a side). ) To insert the screw shaft 4a of the screw 4 by pushing it in. By doing so, the distal end portion of the elastic engagement piece 7b of the screw fixing member 7 accommodated in the accommodation space 6f of the boss portion 6d is pressed against the screw shaft portion 4a. Accordingly, the elastic engagement piece 7b is inclined in the insertion direction P of the screw shaft portion 4a or the inclination in the insertion direction P is increased (in the illustrated embodiment, in the insertion direction P). The screw shaft portion 4a is allowed to move in the insertion direction P by being elastically deformed (inclination increases), and the screw shaft portion 4a is inserted into the hole 7c of the screw fixing member 7 so as to be inserted. It is inserted into the hole 6e. When the push-in of the screw 4 is finished, the tip (specifically, the recess 7d) of the elastic engagement piece 7b engages with the male screw of the screw shaft portion 4a. Thus, the screw 4 is fixed to the boss portion 6 d of the wiring box 5, and the wiring device 2 is attached to the wiring box 5 together with the holding panel 3.

  Here, the insertion hole 6e into which the screw shaft portion 4a is inserted has a first screw restriction hole 6h on the front side of the housing space 6f in which the screw fixing member 7 is housed and a second screw hole on the back side of the housing space 6f. Screw restricting hole 6i. The screw shaft portion 4a is restricted so as to be positioned on the substantially center line 6g of the insertion hole 6e by the first and second screw restricting holes 6h and 6i located so as to sandwich the accommodating space 6f. The screw 4 can be prevented from being inclined with respect to the insertion hole 6e. Thus, by preventing the screw 4 from being inclined with respect to the insertion hole 6e, the elastic engagement piece 7b of the screw fixing member 7 can be accurately engaged with the male screw of the screw shaft portion 4a. In order to make full use of this effect, that is, the effect that the elastic engagement piece 7b can be accurately engaged with the male screw of the screw shaft portion 4a, the screw shaft portion 4a having the maximum diameter in consideration of manufacturing errors. In detail, it is necessary to form the first and second screw restricting holes 6h and 6i in accordance with the screw forming portion 4b. In other words, the diameters of the first and second screw restricting holes 6h and 6i are larger than the screw shaft portion 4a (specifically, the screw forming portion 4b), but the screw shaft portion 4a is substantially above the center line 6g of the insertion hole 6e. This effect is achieved by reducing the size so that it is regulated so as to be positioned in the position.

  The second screw restricting hole 6i in the insertion hole 6e on the back side of the housing space 6f is when the elastic engagement piece 7b is engaged with a male screw located at the tip of the screw forming portion 4b of the screw shaft portion 4a. The sliding surface portion 4c of the screw shaft portion 4a is positioned so as to fit into the second screw restricting hole 6i (see FIG. 7). Therefore, when the screw shaft portion 4a is inserted into the insertion hole 6e and the elastic engagement piece 7b is engaged with the male screw of the screw shaft portion 4a, the screw forming portion 4b of the screw shaft portion 4a is surely formed. Or the smooth surface part 4c will fit in the 2nd screw | thread control hole 6i. Therefore, whenever the elastic engagement piece 7b is engaged with the male screw of the screw shaft portion 4a, the screw 4 is always inclined with respect to the insertion hole 6e by the second screw restriction hole 6i and the first screw restriction hole 6h. Can be prevented.

  Further, when a force in the pulling direction Q acts on the screw 4 and the elastic engaging piece 7b engaged with the male screw of the screw shaft portion 4a tries to deform in the lateral direction, the deformation is caused on both sides of the elastic engaging piece 7b. Deformation restricting portions 8 and 8 provided facing the surfaces 7e and 7e restrict. Thus, the deformation restricting portion 8 can prevent the elastic engagement piece 7b from being deformed in the lateral direction. Thus, by preventing the elastic engagement piece 7b from being deformed in the lateral direction, it is possible to make it difficult for the screw 4 to come off.

  Further, by providing a pair of presser ribs 6m and 6m for partially pressing the plate surface of the body portion 7a of the screw fixing member 7 in the storage space 6f, the presser ribs 6m and 6m can be stored in accordance with the protruding height. The space 6f can be widened. For this reason, formation of this accommodation space 6f becomes easy. In particular, when the box body 6 is resin-molded, the strength of the mold component (slide mold) for forming the accommodation space 6f of the mold used for the resin molding should be resistant to use. it can. Moreover, since the pair of presser ribs 6m and 6m sandwich the screw shaft part 4a, the presser ribs 6m and 6m restrict the tilting of the screw 4 during the insertion of the screw shaft part 4a into the insertion hole 6e. Can do. Furthermore, a screw restricting portion 6n is provided in the insertion hole 6e so as to face the elastic engagement piece 7b, and also by this screw restricting portion 6n, during the insertion of the screw shaft portion 4a into the insertion hole 6e, The inclination of the screw 4 can be restricted.

  By the way, when attaching the wiring device 2 to the wiring box 5, after the screw shaft portion 4a of the screw 4 is pushed into the insertion hole 6e of the wiring box 5, the screw 4 is further rotated in the tightening direction. May be. In this way, the wiring device 2 can be firmly fixed to the wiring box 5 by turning the screw 4 in the tightening direction.

  On the contrary, in order to remove the wiring device 2 from the wiring box 5, the screw 4 engaged with the elastic engagement piece 7b is rotated in the loosening direction. By doing so, the screw 4 is retracted and removed from the boss portion 6 d (specifically, the insertion hole 6 e), and the wiring device 2 is removed from the wiring box 5 together with the holding panel 3.

  In addition, this invention is not necessarily limited to embodiment mentioned above, A various other change is possible. For example, the attachment body is a frame-like attachment body in which the internal space has an open portion on one side and is open to the other side, even if the internal space 6b is not the wiring box 5 having the open portion 6a on one side. May be. As this frame-shaped attachment, for example, there is a wiring box cover to which the wiring device 2 as an attachment is attached and attached to the wiring box. Here, as the wiring box cover, there are a box cover with coating, a plate-shaped box cover, and the like. Further, the attachment body is not limited to the wiring box 5 or the wiring box cover, and any attachment body can be used as long as the attachment object is attached using the screws 4.

  In addition, the attachment object may be a wiring box cover that is attached to the wiring box 5 as the attachment body, and is not limited to the wiring equipment 2, instead of the wiring equipment 2. .

  The first and second screw restricting holes 6h and 6i are formed in a circular cross section in which the screw shaft portion 4a is just fitted, but the screw shaft portion 4a is positioned on a substantially center line 6g of the insertion hole 6e. If restricted, the shape is not limited to a circular cross section, and a part of the screw shaft portion 4a may be partially contacted in the circumferential direction, such as a part thereof being cut out. Even if it is not formed, it may be formed so as to have a slight gap between the screw shaft portion 4a. The first screw restricting hole 6h and the second screw restricting hole 6i are desirably the same diameter, but the first screw on the front side is easy to insert the screw shaft portion 4a into the insertion hole 6e. The diameter of the screw restriction hole 6h may be set slightly larger than the diameter of the second screw restriction hole 6i.

  Further, even if the deformation restricting portions 8 and 8 are not formed so that the elastic engagement piece 7b just fits between the deformation restricting portions 8 and 8, there is a slight gap between the deformation restricting portions 8 and 8. May be formed. Further, even if the deformation restricting portion 8 does not consist of the wall surface that forms the accommodating space 6f, as shown in FIG. 10, the screw fixing member 7, that is, a part of the body portion 7a of the screw fixing member 7 is elastic. The deformation restricting portions 8 and 8 may be formed by being bent so as to face both side surfaces 7e and 7e of the engagement piece 7b.

  Further, the entire elastic engagement piece 7b is formed to be inclined so as to advance in the insertion direction P of the screw shaft portion 4a from the proximal end side toward the distal end side, as shown in FIG. For example, the tip portion may be bent so as to be substantially perpendicular to the center line 6g of the insertion hole 6e.

  Further, the elastic engagement piece 7b may be inclined in the insertion direction P before the screw shaft portion 4a is inserted into the insertion hole 6e, but before the screw shaft portion 4a is inserted, the insertion hole 6e. By inserting the screw shaft portion 4a perpendicularly to the center line 6g, the elastic engagement piece 7b is pushed by the screw shaft portion 4a and is elastic so as to be inclined in the insertion direction P of the screw shaft portion 4a. It may be deformed. Further, the elastic engagement piece 7b may be inclined from the beginning so that the tip of the elastic engagement piece 7b follows the spiral of the male screw of the screw shaft portion 4a.

  The screw fixing member 7 is provided with one elastic engagement piece 7b, but a plurality of elastic engagement pieces 7b may be provided. That is, a pair of elastic engagement pieces 7b may be provided so as to face each other, or three or more elastic engagement pieces 7b may be provided radially.
