An engagement member that is inserted into an engagement hole of the object to be assembled, and the engagement member has a cross-sectional shape corresponding to the size of the engagement hole; and An engaging piece that protrudes from the outer peripheral surface of the main body and can be elastically deformed and reduced so that the main body can be inserted into the engaging hole. The mounting bracket and the article to be assembled are assembled together by being inserted into the engagement hole while being elastically deformed and reduced, and elastically restored in the inserted state.

  An audio device for a vehicle is assembled to an object to be assembled through a mounting bracket. The mounting bracket is provided with an engagement member that is inserted into the engagement hole of the assembly, and the engagement piece of the engagement member is elastically deformed and reduced while the engagement piece is engaged. It is inserted through the hole. And since the said engagement piece elastically restores in the state penetrated by the penetration hole, a mounting bracket and a to-be-assembled object are assembled | attached integrally in the retaining state. The operator only needs to relatively push the mounting bracket and the object to be assembled, so that the operator can assemble with one touch. Further, since the mounting bracket is made of a resin material and has flexibility, the design of the engaging member can be facilitated and the weight can be reduced.

  According to an eleventh aspect of the present invention, on the premise of the tenth aspect of the present invention, the main body portion is a gate type in which a hollow portion is formed in an axial center portion, and the engagement piece is connected to the shaft from the top of the main body portion.

  Examples of the present invention will be described. 1 is an exploded perspective view of the audio device 100, the mounting bracket 111, and the instrument panel 120. FIG. 2 is a plan sectional view of the audio device 100 attached to the instrument panel 120 via a pair of mounting brackets 111. (A) is a front view of the mounting bracket 111 of the first embodiment, (b) is a left side view, and FIG. 4 is a plan sectional view of the mounting bracket 111.

  As shown in FIG. 1, the audio device 100 is attached to an instrument panel 120 of a vehicle (not shown) by a mounting bracket 111 according to the first embodiment of the present invention. As shown in FIG. 2, each mounting bracket 111 is attached to both side walls 1a of the case body 1 of the audio device 100. In FIG. 1, only one side portion of the audio device 100 is shown. Yes.

  First, the audio device 100 will be described. As shown in FIG. 1, the audio device 100 according to the present embodiment includes a case body 1 made of a metal material and two audio device units 2 housed in the case body 1 in two upper and lower stages. Yes. Here, the height of the audio device 100 for a vehicle is determined by the standard, and the height of the single audio device 2 is “1 DIN (50 mm)”. For this reason, the case body 1 shown in FIG. 1 is of 2DIN. “DIN” is an abbreviation for Deutsche Industrie Normen.

  Each side wall 1a of the case body 1 is provided with respective locking holes 3 and 4 and a retaining hole 5. In the case body 1 of the present embodiment, each of the locking holes 3 and 4 and the retaining hole 5 has a predetermined interval in the depth direction from the front portion of the audio device unit 2 and has two stages (two Corresponding to each of the audio device units 2). Each of the locking holes 3 and 4 and the retaining hole 5 is square, but their sizes are different. Further, since the actions of the upper and lower locking holes 3 and 4 and the retaining hole 5 are the same, only the lower locking holes 3 and 4 and the retaining hole 5 will be described in this specification.

  Next, the mounting bracket 111 of the first embodiment will be described. Here, since the mounting bracket 111 is symmetrical in the vertical direction, the same mounting bracket 111 can be disposed on any side wall 1 a of the case body 1 of the audio device 100. Therefore, in the present specification, only the mounting bracket 111 disposed on the right side wall portion 1a of the case body 1 of the audio device 100 in front view will be described below. The mounting bracket 111 is made of a flexible resin material such as polyacetal or polyamide, and includes a case body mounting portion 6 that comes into contact with the side wall portion 1a of the case body 1 and a front side of the case body mounting portion 6 in the mounted state. A panel assembling portion 7 is provided that is bent substantially perpendicularly from the end toward the outside (the side opposite to the side wall portion 1a of the case body 1). For this reason, the mounting bracket 111 is substantially L-shaped in plan view. As shown in FIGS. 3A and 3B, the case body mounting portion 6 has locking members (corresponding to the locking holes 3 and 4 and the locking holes 5 corresponding to the upper and lower locking holes 5). The sandwiching pieces 8 and 9 corresponding to the retaining holes 3 and 4 and the retaining pieces 11 corresponding to the retaining holes 5 are provided, and the mounting surface 6a (the side wall of the case body 1 in the case mounting portion 6). A large number of the abutment ribs 12 protrude from the surface on the side facing the portion 1a. The size of the protruding surface of each abutment rib 12 is extremely small compared to the size of the mounting surface 6 a of the case body mounting portion 6.

  Each abutment rib 12 minimizes the influence of a molding defect called “sink” in the case body mounting portion 6 when the mounting bracket 111 is molded, and the flatness of the mounting surface 6a is deteriorated. It is provided for. That is, when the mounting bracket 111 is attached to the case body 1, the side wall portion 1 a of the case body 1 comes into contact with each abutment rib 12. Thereby, even if the flatness of the case body attaching portion 6 is poor, there is an effect that the case body 1 and the case body attaching portion 6 are reliably brought into contact with each other. Of the abutment ribs 12, the abutment ribs 12 a provided in the vicinity of the sandwiching pieces 8 and 9 make the relative sliding (described later) of the mounting bracket 111 and the case body 1 easy. An inclined surface 12b that is gentler than the end portion on the near side is formed at the end portion. The inclined surface 12b of the abutment rib 12a gradually reduces the amount of protrusion to the portion (back side) of the case body 1 on the side (back side) that first contacts the opening edge portions 3b, 4b of the engagement holes 3, 4. It is formed in the form to make. For this reason, when the mounting bracket 111 and the case body 1 are relatively slid, the side wall portion 1a of the case body 1 rides along the inclined direction of the inclined surface 12b of the abutment rib 12a, so that the work is easy. Therefore, less force is required for the operator to slide both of them.

  Next, the sandwiching pieces 8 and 9 will be described. The structures of the sandwiching pieces 8 and 9 are substantially the same except that their heights H1 and H2 (see FIG. 3) are different, so that they are on the near side (side closer to the panel assembly portion 7). Only the sandwiching piece 8 will be described. As shown in FIGS. 3 and 4, the sandwiching piece 8 protrudes from the mounting surface 6 a of the case body mounting portion 6, is provided in a substantially L shape in plan view, and the tip portion is further provided. It is a form in which the guide portion 8a is formed at the portion by being bent. And the part of the inner side (the side opposite to the attachment surface 6a of the case body attaching part 6) of the sandwiching piece 8 is slightly raised, and the contact part 13 for pressing the side wall part 1a of the case body 1 is provided. Is formed. The gap e between the abutment rib 12 and the contact portion 13 is slightly smaller than the thickness t of the side wall portion 1a of the case body 1 (e <t). Further, the height H 1 of the sandwiching piece 8 is slightly smaller than the inner height 3 a of the locking hole 3. As will be described later, the sandwiching piece 8 of the mounting bracket 111 is guided by the guide portion 8a to enter the locking hole 3 of the side wall portion 1a of the case body 1 and is relatively slid to sandwich the side wall portion 1a. . Here, the gap e is smaller than the thickness t of the side wall 1a. For this reason, the side wall portion 1a of the case body 1 pushed into the gap e elastically deforms the sandwiching piece 8 (that is, rotates around the base end 8b of the sandwiching piece 8 as a fulcrum). Expand. And it is closely_contact | adhered to the contact part 13 with the elastic restoring force of the clamping piece 8. FIG. Thereby, the mounting bracket 111 that has entered the locking hole 3 in the side wall 1a of the case body 1 is held in a locked state. In the case body mounting portion 6, a portion corresponding to the sandwiching piece 8 is extracted to form the sandwiching piece 8 when the mounting bracket 111 is formed, and a hole 14 is formed. Further, a portion corresponding to the sandwiching piece 9 is similarly cut out, and a cut portion 15 is formed.

  Next, the retaining piece 11 will be described. As shown in FIGS. 3 and 4, a retaining piece 11 is provided between the sandwiching pieces 8 and 9 provided on the case body attaching portion 6 of the attaching bracket 111. In the case body attaching portion 6, the peripheral portion excluding the base end portion 11 a of the retaining piece 11 is extracted to form a hole 16. Further, the distal end portion of the retaining piece 11 is bent in an L shape toward the surface opposite to the mounting surface 6 a of the case body mounting portion 6, and when the mounting bracket 111 attached to the case body 1 is removed. In addition, an operation portion 11 b is formed for the operator to release the locking state of the retaining piece 11. A locking portion 17 having a triangular cross section protruding from the mounting surface 6 a of the case body mounting portion 6 is provided on the side of the mounting surface 6 a of the case body mounting portion 6 in the retaining piece 11. The inclination of the oblique side 17a on the near side in the locking part 17 is steeper than the inclination of the oblique side 17b on the back side. In the case of the mounting bracket 111 of the present embodiment, the inclination angle α of the oblique side portion 17a on the near side (angle with respect to the attachment surface 6a) is 60 to 70 degrees, and the inclination angle β of the oblique side portion 17b on the back side is 20 to 30 degrees. It is. Here, the height H3 (see FIG. 3) of the retaining piece 11 is slightly smaller than the inner height 5a (see FIG. 1) of the retaining hole 5 of the corresponding side wall 1a of the case body 1. When the sandwiching pieces 8, 9 of the mounting bracket 111 enter the respective locking holes 3, 4 of the side wall 1 a of the case body 1 and are relatively slid, the retaining piece 11 becomes the side wall of the case body 1. It is fitted in the retaining hole 5 of 1a. Then, the oblique side portion 17a of the locking portion 17 of the retaining piece 11 and the opening edge portion 5b of the retaining hole 5 are brought into contact with each other (see FIG. 5). Thereby, the retaining piece 11 of the mounting bracket 111 and the retaining hole 5 of the case body 1 are locked, and the mounting bracket 111 and the case body 1 are held in a retaining state.

  As shown in FIG. 1 and FIG. 3A, the panel assembly 7 of the mounting bracket 111 of the first embodiment is provided with four through holes in the height direction. The uppermost and lowermost through holes are screw insertion holes 19 through which the mounting screws 18 (see FIG. 1) are passed, and the through holes provided directly above or directly below the respective screw insertion holes 19 This is a pin insertion hole 22 for passing a positioning pin 21 provided in the ment panel 120. The mounting screw 18 inserted through the screw insertion hole 19 of the panel assembly 7 is screwed into a spring plate 23 attached to a screw hole (not shown) portion of the instrument panel 120. Thereby, the mounting bracket 111 is positioned and assembled to the instrument panel 120 of the vehicle. In FIG. 4, 24 is a rib formed in a lattice shape on the case body mounting portion 6 in order to reinforce the case body mounting portion 6 of the mounting bracket 111, and 25 is a panel assembly of the mounting bracket 111. It is a rib for reinforcing the attachment portion 7.

  An operation when the mounting bracket 111 of the first embodiment is mounted on the case body 1 of the audio device 100 will be described. As shown in FIGS. 1 and 4, the mounting bracket 111 is addressed to the side wall 1 a of the case body 1 of the audio device 100, and the sandwiching pieces 8 and 9 provided on the mounting bracket 111 correspond to the corresponding latches. Enter holes 3 and 4. The inner heights 3a and 4a and inner lengths of the respective locking holes 3 and 4 are slightly larger than the heights H1 and H2 and the lengths of the corresponding sandwiching pieces 8 and 9, respectively. Enters the corresponding locking holes 3 and 4 without hindrance. In addition, the mounting bracket 111 is configured such that the guide portions 8a and 8b of the sandwiching pieces 8 and 9 are first inserted into the corresponding locking holes 3 and 4, and then the entirety thereof is inserted. However, the operation of finding each of the locking holes 3 and 4 in the side wall 1a of the case body 1 is easy. Further, since the heights H1 and H2 of the sandwiching pieces 8 and 9 are different, each sandwiching piece 8 and 9 is inserted even when the operator mistakenly points the front-rear direction (depth direction) of the mounting bracket 111. The pieces 8 and 9 cannot enter the corresponding locking holes 3 and 4. As a result, it is possible to prevent the attachment position from being erroneously attached.

  As shown in FIG. 5A, when the mounting bracket 111 is addressed to the side wall 1 a of the case body 1, the locking portion 17 of the retaining piece 11 is pulled out at the side wall 1 a of the case body 1. Since it is brought into contact with a position where the stop hole 5 is not provided, it is pressed against the side wall 1a to be elastically deformed, and is rotated toward the outside of the case body mounting portion 6 with the base end portion 11a as a fulcrum. . In this state, the case body 1 and the mounting bracket 111 are relatively slid along the depth direction of the case body 1. In a normal case, in order to slide the mounting bracket 111 with respect to the case body 1 in a stationary state, the sliding direction is indicated by an arrow 26 in FIG. Here, the gap e (see FIG. 4) between the abutting rib 12a and the abutting portion 13 of the sandwiching piece 8 is smaller than the thickness t of the side wall portion 1a. 13, the side wall 1 a of the case body 1 arranged between the side wall 13 and the mounting bracket 111 is slid to elastically deform the sandwiching piece 8 to expand. And it slides in contact with the contact part 13 of the abutment rib 12a and the pinching piece 8, and closely. Thereby, the variation in the width direction of the side wall portion 1a in the mounting bracket 111 and the case body 1 is absorbed, and there is no possibility that the case body 1 of the audio device 100 is wobbled in the width direction.

  As shown in FIG. 5B, when the mounting bracket 111 is slid, the locking portion 17 of the retaining piece 11 is disposed in the retaining hole 5 of the side wall portion 1 a of the case body 1. The retaining piece 11 is gradually rotated in the direction of the arrow 27 with its base end portion 11a as a fulcrum by its own elastic restoring force. The retaining piece 11 that has entered the retaining hole 5 of the side wall portion 1 a comes into contact with the oblique side portion 17 a on the near side and the opening edge portion 5 b of the retaining hole 5. Since the locking portion 17 of the retaining piece 11 has a triangular cross section, the oblique side portion 17a and the opening edge portion 5b of the retaining hole 5 are reliably brought into contact with each other. Further, when the mounting bracket 111 is slid, the opening edge 3 b of the locking hole 3 comes into contact with the inner wall surface of the proximal end portion 8 b of the sandwiching piece 8. In this state, since the retaining piece 11 is held in a state of being elastically restored, the oblique side portion 17a of the locking portion 17 of the retaining piece 11 and the opening edge portion 5b of the retaining hole 5 are applied with elastic force. Touched. In other words, the distance L between the opening edge portions 3 b and 5 b of the locking hole 3 and the retaining hole 5 in the side wall portion 1 a of the case body 1 is set so that the opening edge portion 3 b of the locking hole 3 is the base of the sandwiching piece 8. The opening edge portion 5b of the retaining hole 5 is set to be pressed against the oblique side portion 17a of the locking portion 17 of the retaining piece 11 in a state where it abuts against the inner wall surface of the end portion 8b. Thereby, the variation in the depth direction (slide direction) between the mounting bracket 111 and the side wall portion 1a of the case body 1 is absorbed, and there is no possibility that the case body 1 of the audio device 100 rattles in the depth direction.

  Further, even if vibration due to running of the vehicle occurs and the mounting bracket 111 and the side wall portion 1a of the case body 1 try to slide relative to each other, the locking portion 17 of the retaining piece 11 is resisted against its elastic restoring force. As long as no force for rotating in the reverse direction of the arrow 27 is generated, there is no possibility that the locked state between the locking portion 17 of the retaining piece 11 and the retaining hole 5 is released. In addition, since the inclined portion 17a of the locking portion 17 is steeply inclined, a force for rotating the retaining piece 11 in the reverse direction is hardly generated. Thereby, the securing state of the mounting bracket 111 and the case body 1 is reliably held.

  When it is necessary to remove the mounting bracket 111 from the case body 1 due to repair or the like, the operator uses a predetermined tool (for example, pliers or the like) to operate the operation portion 11b provided at the distal end portion of the retaining piece 11. The retaining piece 11 is rotated in the reverse direction of the arrow 27 with the base end portion 11a as a fulcrum. Thereby, the locking state of the locking portion 17 of the retaining piece 11 and the retaining hole 5 is released. Then, it is only necessary to slide the mounting bracket 111 and the case body 1 relative to each other and to remove the sandwiching pieces 8 and 9 from the respective locking holes 3 and 4 of the case body 1.

  Next, an effect | action at the time of assembling the audio apparatus 100 with which the attachment bracket 111 was attached to the instrument panel 120 of a vehicle is demonstrated. As shown in FIG. 1, the panel assembly portion 7 of the mounting bracket 111 is directed to the instrument panel 120 of the vehicle. At this time, each positioning screw 21 protruding from the instrument panel 120 is inserted into the pin insertion hole 22 of the corresponding panel assembly portion 7, and each mounting screw 18 is a screw of the panel assembly portion 7. It is inserted through the insertion hole 19. Then, each mounting screw 18 is screwed to each spring plate 23 attached to a screw hole (not shown) of the instrument panel 120. Thereby, the audio apparatus 100 is assembled | attached to the instrument panel 120 of a vehicle via a pair of attachment bracket 111. FIG.

A base end portion 43 a of each retaining piece 43 is connected to the main body portion 38. In addition, each retaining piece 43 is formed with a locking portion 43 b that protrudes outward from the outer peripheral surface of the main body portion 38 and a tongue-like protrusion 43 c that protrudes inward from the inner peripheral surface of the screw insertion hole 42. . And since the groove part 44 is formed in the part of the base end part 43a of the retaining piece 43, and the thickness is thin, the retaining piece 43 can be rotated using the base end part 43a as a fulcrum. . In FIG. 8, reference numeral 38 c denotes a protrusion for absorbing rattling with the grommet insertion hole 39 when the main body 38 of the screw grommet 36 is inserted into the grommet insertion hole 39 of the instrument panel 120. .

  The operation of the mounting bracket 113 of the third embodiment will be described. As shown in FIG. 9, the top 38 a of the main body 38 of the screw grommet 36 is inserted into the grommet insertion hole 39 of the instrument panel 120. The engaging portions 43 a of the pair of retaining pieces 43 of the screw grommet 36 are brought into contact with the inner peripheral surface of the grommet insertion hole 39 of the instrument panel 120. When the mounting bracket 113 is pushed in as it is, the respective locking portions 43b of the pair of retaining pieces 43 of the screw grommet 36 are elastically deformed and rotated in the direction of the arrow 45 with their base end portions 43a as fulcrums. Each tongue-like protruding piece 43 c of the pair of rotated retaining pieces 43 is accommodated in the screw insertion hole 42. Thereby, the main-body part 38 of the screw grommet 36 is pushed into the grommet insertion hole 39 as it is.

  As shown in FIG. 10A, when the pair of retaining pieces 43 of the screw grommet 36 pass through the grommet insertion holes 39 of the instrument panel 120, the contact between the respective locking portions 43 b and the grommet insertion holes 39 is achieved. The contact state is released, and each retaining piece 43 is elastically restored and rotated in the reverse direction of the arrow 45. The instrument panel 120 is disposed between each locking portion 43 b of the pair of retaining pieces 43 of the screw grommet 36 and the back surface portion of the panel assembly portion 37. The locking portions 43b of the pair of retaining pieces 43 of the screw grommets 36 are disposed so as to cover the instrument panel 120, and the tongue-like protruding pieces 43c are arranged from the inner peripheral surface of the screw insertion hole 42 to the inner side. It protrudes toward the direction.

  In this state, as shown in FIG. 10B, the mounting screw 41 is inserted into the screw insertion hole 42 of the screw grommet 36 and screwed. As a result, the pair of retaining pieces 43 of the screw grommet 36 are pushed outward, so that the area where the engaging portions 43b of the pair of retaining pieces 43 cover the grommet insertion holes 39 is increased. Further, the pair of retaining pieces 43 is prevented from rotating inward (in the direction of the arrow 44).
