In the fixed state of the mounting part, the pressure contact portions on both side walls of the main body are pressed against the inner peripheral surface of the mounting hole of the panel, and the check pawl piece firmly bites into the side surface of the boss portion.

JP-A-8-121441

  When a mounting part is mounted in a vehicle interior using a clip described in Japanese Patent Application Laid-Open No. 8-121441, if a load in the direction of separation acts on the mounting part in the event of a vehicle collision, the mounting part is attached to the panel. There is a possibility of jumping out of the hole and hitting a passenger in the passenger compartment.

  The above inconvenience can be avoided to some extent by increasing the engagement force of the elastic engagement piece with respect to the mounting hole of the panel, but it cannot be avoided reliably, and if the engagement force of the elastic engagement piece is increased. The mounting workability of the mounting parts will be impaired.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a clip capable of reliably restricting the movement of the mounting component when it is detached without impairing the mounting workability.

  In order to achieve the above object, the present invention is a clip that is fixed to an attachment part and inserted into an engagement hole of the counterpart panel in order to attach the attachment part to the counterpart panel, and is connected to the stopper portion and the locking portion. And an operation unit.

  The stopper portion is provided on the insertion tip end side of the clip, and is elastically deformed into an insertable shape when inserted into the engagement hole, is inserted through the engagement hole, and is restored to the separation preventing shape in a state where the engagement hole is inserted. The stopper portion having the separation preventing shape is prevented from moving in the anti-insertion direction by contacting the inner peripheral side of the peripheral edge portion of the engagement hole.

  The locking portion is provided closer to the insertion base end than the stopper portion, and elastically deforms when entering the engaging hole through which the stopper portion is inserted, and enters the engaging hole. The locking portion that has entered the engagement hole engages with the peripheral edge of the engagement hole and is held by the counterpart panel.

  The connecting portion connects the stopper portion and the locking portion. The connecting portion forms a gap between the attachment component and the counterpart panel in a state where the stopper portion is inserted through the engagement hole and the locking portion is not inserted into the engagement hole.

  The operating portion extends from the stopper portion to the insertion proximal end side, and is elastically deformed from the separation preventing shape to the insertable shape by being pressed.

  In the above configuration, when the attachment component is attached to the counterpart panel, the stopper portion is inserted into the engagement hole from the insertion tip side. The stopper portion is elastically deformed into an insertable shape when inserted into the engagement hole, is inserted through the engagement hole, and is restored to the separation preventing shape while being inserted through the engagement hole. Next, the locking portion is inserted into the engagement hole from the insertion tip side. The engaging part that has entered the engaging hole is engaged with the peripheral part of the engaging hole by its own spring reaction force and is held by the mating panel.

  Also, when a load in the disengagement direction acts on the mounting part in the event of a vehicle collision, etc., the engagement between the locking part and the peripheral edge of the engagement hole is released, and the attachment part is disengaged from the engagement hole of the counterpart panel The stopper part with the separation preventing shape abuts against the inner surface side of the peripheral edge of the engagement hole to prevent the clip from moving in the anti-insertion direction (detachment direction). Regulated reliably. Therefore, even when the mounting part is mounted in the vehicle interior using the clip, it is possible to reliably prevent the mounting part from coming off and hitting a passenger in the vehicle interior at the time of a vehicle collision or the like.

  Further, when removing the attachment part from the mating panel, the clip (attachment part) is moved in the anti-insertion direction against the engagement force of the locking part, the engagement part is pulled out from the engagement hole, An engagement hole is positioned between the stopper portion. In this state, the connecting part forms a gap between the mounting part and the mating panel, so a rod-shaped jig or the like is inserted from this gap, and the operation part is pressed by the inserted jig or the like to prevent the stopper part from being separated. In this state, the clip (attachment part) is further moved in the anti-insertion direction, and the stopper portion is inserted into the engagement hole and pulled out from the engagement hole.

  As described above, according to the clip, the movement at the time of detachment of the attachment part can be reliably regulated without impairing the attachment workability.

  The clip may include a clip body having a locking portion, a stopper portion, a coupling portion, and an operation portion, and a plate-shaped fixing spring, and may be detachably fixed to the plate-shaped mounting portion of the mounting component. . The plate-like mounting portion has a projecting piece insertion hole.

  The clip body is formed by bending a metal plate, and integrally includes a pair of attachment pieces, a pair of locking pieces, and a pair of support pieces. The pair of attachment pieces has a V-shape that is bent on the insertion tip side as a whole, and a plate-like attachment portion is inserted therein. The pair of locking pieces are bent outward from both ends on the base end side of the attachment piece, and are inverted and extended to the insertion distal end side. The locking piece is bent in a substantially L shape so that the middle of the locking piece protrudes outward, and functions as a locking portion. One of the pair of attachment pieces has a protruding piece that protrudes inward above the protruding piece insertion hole. The pair of support pieces protrudes outward from the end portion on the insertion base end side of each locking piece. The fixing spring has an insertion hole into which the clip body is inserted.

  When the clip body is inserted into the insertion hole of the fixing spring with the plate-like attachment part inserted inside the attachment piece, the stopper part is elastically deformed and inserted through the insertion hole to restore the initial state, and then a pair of engagements. The stop piece enters the insertion hole. During this approach, the inclined portion on the insertion tip side of the locking piece is pressed against the periphery of the insertion hole and the locking piece is elastically deformed inward, and the insertion hole is engaged beyond the inclined portion on the insertion tip side of the locking piece. In a state in which it reaches between the inclined portion on the insertion base end side of the stop piece and the support piece, the peripheral edge portion of the insertion hole of the fixed spring is caused by the spring reaction force of the locking piece and the inclined portion on the insertion base end side and the support piece. Held between. Further, due to the elastic deformation to the inside of the locking piece, the attachment piece as a whole is deformed from V shape to U shape to sandwich the plate-like attachment portion from both sides, and the protrusion moves to the inside. Enter the insertion hole. Thereby, a clip main body is fixed to a plate-shaped attaching part. In addition, by moving the fixing spring in the anti-insertion direction and removing it from the clip body, the attachment piece is restored to a V shape, and the clip body can be removed from the plate-like attachment portion.

  When attaching the attachment part to the mating panel, the stopper portion is inserted into the engagement hole from the insertion tip side. The stopper portion is elastically deformed into an insertable shape when inserted into the engagement hole, is inserted through the engagement hole, and is restored to the separation preventing shape while being inserted through the engagement hole. Next, the locking piece is inserted into the engagement hole from the insertion tip side. The locking piece that has entered the engagement hole has its inclined portion on the insertion tip side pressed against the periphery of the engagement hole and elastically deforms inward, and the engagement hole exceeds the inclined portion on the insertion tip side of the locking piece. In this state, the peripheral edge portion of the engagement hole is inserted into the insertion base end by the spring reaction force of the engagement piece and the spring reaction force of the fixation spring. It is held between the inclined portion on the side and the fixed spring.

  According to the present invention, it is possible to reliably regulate the movement of the mounting component when it is detached without impairing the mounting workability.

  As shown in FIGS. 1 to 7, the clip 1 of the present embodiment is fixed to the mounting part 2 in order to attach the mounting part 2 such as a cluster arranged on the front surface of the vehicle compartment to the counterpart panel 3 on the vehicle body side. And is inserted into the engagement hole 4 of the counterpart panel 3, and includes a clip body 5 and a fixing spring 6.

  As shown in FIG. 4, a panel connecting portion 8 that is attached to the mating panel 3 via the clip 1 is formed on the back surface of the component body 7 of the attachment component 2. The panel connecting portion 8 includes a pair of outer plate portions 9 that protrude from the component main body 7 so as to face each other, and a plate-like mounting portion 10 that connects intermediate portions of the outer plate portions 9 together. The panel connecting portion 8 has an H-shaped cross section as a whole, and a projecting piece insertion hole 11 penetrating the plate-like mounting portion 10 is formed at an intermediate portion of the plate-like mounting portion 10. The clip 1 is detachably fixed to the plate-like mounting portion 10.

  As shown in FIGS. 1 and 6, the mating panel 3 has a clip attachment portion 12, and an engagement hole 4 into which the clip 1 is inserted is formed in the clip attachment portion 12. The engagement hole 4 has a rectangular shape corresponding to the panel connecting portion 8 of the attachment component 2, and the peripheral portion of the engagement hole 4 is spaced apart in the vertical direction in FIG. 6 includes another pair of movement blocking portions 14 that are spaced apart from each other in the left-right direction. The plate-like attachment portion 10 of the attachment component 2 to which the clip 1 is fixed is attached to the counterpart panel 3 via the clip 1 by being inserted into the engagement hole 4 of the counterpart panel 3. The movement prevention part 14 faces the outer side plate part 9 of the panel connecting part 8 and restricts the movement of the attachment part 2 in the lateral direction (left and right rear in FIG. 6).

  As shown in FIGS. 1 to 3, the clip body 5 is formed by bending a metal plate punched into a predetermined shape, and includes a pair of attachment pieces 15, a pair of locking pieces (locking portions) 16, and a pair. The support piece 17, the connection piece (connection part) 18, a pair of stopper pieces (stopper part) 19, and an operation piece (operation part) 20 are integrally provided.

  The pair of attachment pieces 15 has a V-shape that is bent on the insertion tip side as a whole, and the plate-like attachment portion 10 of the attachment component 2 is inserted therein. One of the pair of mounting pieces (upper in the figure) is formed with a protruding piece 21 that protrudes inwardly above the protruding piece insertion hole 11 of the plate-like mounting portion 10, and the other of the pair of mounting pieces 15 (lower in the figure). ), A protruding piece insertion hole 22 corresponding to the protruding piece insertion hole 11 is formed.

  The pair of locking pieces 16 are bent outward from the ends on both sides of the base end side of the attachment piece 15 and are inverted and extended to the insertion distal end side. Each locking piece 16 is bent in a substantially L shape so that the middle protrudes outward. The pair of locking pieces 16 are provided closer to the insertion base end side than the stopper piece 19 and are inserted into the engagement hole 4 from the insertion distal end side to be elastically deformed and enter the engagement hole 4. As will be described later, the engaging portion that has entered the engaging hole 4 engages with the clip mounting portion 13 at the periphery of the engaging hole 4 and is held by the counterpart panel 3.

  The pair of support pieces 17 are bent from the end portion on the insertion base end side of each locking piece 16 and protrude outward (in a direction away from the plate-like attachment portion 10).

  The connecting piece 18 extends from one end of the pair of locking pieces 16 (downward in the drawing) to the insertion tip side, and a stopper piece 19 is bent from the tip portion. The connecting piece 18 is a state where the stopper piece 19 is inserted through the engagement hole 4 and the locking piece 16 is not inserted into the engagement hole 4 (the state shown in FIG. 7). A gap is formed between them.

  The pair of stopper pieces 19 are arranged on the most distal end side of the clip body 5 and have a V shape that is bent on the distal end side as a whole. One of the pair of stopper pieces 19 (downward in the figure) continues to the end of the connecting piece 18 via a protrusion 23 protruding outward. The other of the pair of stopper pieces 19 (upper in the drawing) has a step portion 24 formed by bending the end portion on the insertion base end side inward at an acute angle. The operation piece 20 extends integrally from the insertion base end side. When the operation piece 20 is pressed inward, the stopper piece 19 is elastically deformed from a later-described detachment preventing shape to an insertable shape. The connecting piece 18 is formed with a hole 25 for avoiding interference between the deformed operating piece 20 and the connecting piece 18.

  When the stopper piece 19 is inserted into the engagement hole 4, the inclined portion of the stopper piece 19 moves while contacting the clip mounting portion 13 on the periphery of the engagement hole 4, and the stopper piece 19 is pressed by the clip mounting portion 13. The engagement hole 4 is inserted into the insertable shape by elastic deformation. The stopper piece 19 inserted through the engagement hole 4 is restored to the separation preventing shape. The stopper piece 19 having a separation preventing shape is prevented from moving in the anti-insertion direction by contact with the inner surface side of the clip mounting portion 13.

  As shown in FIG. 5, the fixed spring 6 has a rectangular plate shape formed by punching a metal plate into a predetermined shape, and has an insertion hole 30 into which the clip body 5 is inserted at a central portion thereof. The insertion hole 30 has a rectangular shape corresponding to the panel connecting portion 8 of the attachment component 2, and the peripheral edge of the insertion hole 30 is separated from the pair of clip body engaging portions 31 facing each other in the vertical direction in the figure, And a pair of other movement restricting portions 32 that are spaced apart from each other in the middle / left / right direction. The movement restricting portion 32 faces the outer plate portion 9 of the panel connecting portion 8 and restricts the movement of the fixed spring 6 in the lateral direction (left and right rear in FIG. 4).

  When the stopper piece 19 shown in FIGS. 1 to 3 is inserted into the insertion hole 30 of the fixing spring 6, the inclined portion of the stopper piece 19 moves while contacting the clip body engaging portion 31 on the periphery of the insertion hole 30, The stopper piece 19 is pressed by the clip main body engaging portion 31 to be elastically deformed inward and inserted through the insertion hole 30.

  Further, when the clip body 5 is inserted into the insertion hole 30 of the fixing spring 6 with the plate-like attachment portion 10 of the attachment component 2 inserted between the attachment pieces 15, the stopper piece 19 is elastically deformed as described above. After inserting the insertion hole 30, the pair of locking pieces 16 enter the insertion hole 30. At this time, the inclined portion 16a on the insertion tip side of the locking piece 16 moves while contacting the clip body engaging portion 31 at the periphery of the insertion hole 30, and the locking piece 16 is pressed by the clip body engaging portion 31. Thus, the clip body engaging portion 31 reaches between the inclined portion 16 b on the insertion proximal end side and the support piece 17 beyond the inclined portion 16 a on the insertion distal end side of the locking piece 16. The clip main body engaging portion 31 reached between the insertion proximal end inclined portion 16 b and the support piece 17 is formed between the insertion proximal end inclined portion 16 b and the support piece 17 by the spring reaction force of the locking piece 16. Retained. Further, due to the elastic deformation of the locking piece 16 to the inside, the attachment piece 15 as a whole is deformed from a V shape to a U shape to sandwich the plate-like attachment portion 10 from both sides, and the protruding piece 21 moves inward. Then, the projection piece insertion hole 11 is inserted, and the projection piece insertion hole 22 on the opposite side is entered. As a result, the clip body 5 is fixed to the plate-like mounting portion 10. In addition, by moving the fixing spring 6 in the anti-insertion direction and removing it from the clip body 5, the attachment piece 15 is restored to a V shape, and the clip body 5 can be removed from the plate-like attachment portion 10.

  In the clip body 5 in a state of being fixed to the plate-like mounting portion 10 by the fixing spring 6, the L-shaped bent portions of the pair of locking pieces 16 are most separated from each other, and the distance is determined by the panel mounting portion of the engagement hole 4. The distance between them and the distance between the clip body engaging portions 31 of the insertion hole 30 are set larger. The distance between the pair of stopper pieces 19 on the insertion base end side is also set larger than the distance between the panel mounting portions of the engagement holes 4 and the distance between the clip main body engagement portions 31 of the insertion holes 30.

  When the attachment part 2 is attached to the mating panel 3, the clip body 5 is fixed to the attachment part 2 by the fixing spring 6 as described above, and then the stopper piece 19 of the clip body 5 is inserted into the engagement hole 4 from the insertion tip side. To do. The stopper piece 19 is elastically deformed into an insertable shape when inserted into the engagement hole 4, is inserted through the engagement hole 4, and is restored to the separation preventing shape in a state where the engagement hole 4 is inserted. Next, the locking piece 16 is inserted into the engagement hole 4 from the insertion tip side. The locking piece 16 that has entered the engagement hole 4 is elastically deformed inward by the inclined portion on the insertion tip side being pressed by the clip mounting portion 13 at the periphery of the engagement hole 4, so that the clip mounting portion 13 becomes the locking piece. When the clip mounting portion 13 reaches the space between the inclined portion on the insertion proximal end side of the locking piece 16 and the fixed spring 6 beyond the inclined portion on the insertion distal end side of the insertion piece 16, The fixed spring 6 is held between the inclined portion on the insertion base end side and the fixed spring 6 by the spring reaction force of the fixed spring 6.

  In addition, when the vehicle collides or the like, a load in the disengagement direction acts on the mounting part 2, the engagement between the locking piece 16 and the clip mounting part 13 is released, and the mounting part 2 is detached from the engagement hole 4 of the counterpart panel 3. When this occurs, the stopper piece 19 (step 24) having a separation preventing shape comes into contact with the inner surface side of the clip mounting portion 13 to prevent the clip from moving in the anti-insertion direction (detachment direction). Movement in the direction is reliably regulated by the stopper piece 19. Therefore, even when the mounting part 2 is mounted in the vehicle interior using the clip 1, it is possible to reliably prevent the mounting part 2 from coming off and hitting a passenger in the vehicle interior at the time of a vehicle collision or the like. .

  Further, when removing the attachment part 2 from the counterpart panel 3, the clip 1 (attachment part 2) is moved in the anti-insertion direction against the engaging force of the locking piece 16, and the engagement piece is removed from the engagement hole 4. The engagement hole 4 is positioned between the engagement piece and the stopper piece 19 by pulling out. In this state, since the connecting piece 18 forms a gap between the attachment part 2 and the mating panel 3, a rod-shaped jig 33 (shown in FIG. 7) or the like is inserted from this gap, and the operation is performed by the inserted jig 33 or the like. By pressing the piece 20, the stopper piece 19 is elastically deformed from the separation preventing shape to the insertable shape, and in this state, the clip 1 (attachment part 2) is further moved in the anti-insertion direction, and the stopper piece 19 is moved to the engagement hole 4. It is made to enter and pulled out from the engagement hole 4.

  As described above, according to the clip 1, the movement of the attachment component 2 when detached can be reliably regulated without impairing the attachment workability.

  In the above-described embodiment, the structure in which the clip body 5 is detachably fixed to the attachment component 2 by the fixing spring 6 has been described. However, the present invention is not limited to this, and for example, the plate-like attachment portion 10 Various other structures are provided such as a check pawl piece that bites into the clip main body 5 and the clip main body 5 is fixed to the mounting part 2 by this check pawl piece or the clip main body 5 is fastened and fixed to the mounting part 2 with bolts. The present invention can be applied to.

  As mentioned above, although the embodiment to which the invention made by the present inventor is applied has been described, the present invention is not limited by the discussion and the drawings that form part of the disclosure of the present invention according to this embodiment. That is, it should be added that other embodiments, examples, operation techniques, and the like made by those skilled in the art based on this embodiment are all included in the scope of the present invention.
