Description

  In particular, the present invention relates to an easily dismantled clip that can easily release the engagement state of the engagement leg portion with respect to the mounting hole on the panel side.

  As the clip structure, for example, in consideration of reuse, separation and collection, etc., it is required that the locked state with respect to the panel can be released when necessary, and various types of clip structures have been proposed conventionally. 7 and 8 show such an easy disassembly clip. A clip 50 shown in FIG. 7 is disclosed in Patent Document 1, and includes a flat substrate (large diameter head) 51, a substantially U-shaped frame (base) 52 provided below the substrate 51, and a frame A pair of engaging leg portions (locking leg pieces) 53 projecting upward from the bottom surfaces on both sides of the head 52. Each engagement leg portion 53 projects outward as it goes upward, and has an operation piece portion 54 that protrudes from the upper end side via a locking step portion 55. The substrate 51 is provided with a notch 56 corresponding to each operation piece 54. The above clip 50 is used when the upper panel 57 is attached to the lower panel 58, and when the frame portion 52 and the engagement leg portion 53 are inserted into the attachment holes 57a, 58a of the upper and lower panels 57, 58, the engagement is achieved. The two panels 57 and 58 are sandwiched between the stop portion 55 and the substrate 51 and locked. The locked state is released by causing the operating piece portions 54 on both sides to approach each other with a finger or the like and swinging each engaging leg portion 53 in the diameter reducing direction as shown in FIG. For this reason, the clip 50 can be easily pulled out from the mounting holes 57a and 58a.

Further, the clip 60 of FIG. 8 is disclosed in Patent Document 2, and includes a flat board 61 and first and second locking parts 62 and 63 provided on both sides of the board 61. . The first locking portion 62 includes a hollow insertion portion 64, an elastic leg portion 65 that is connected to the distal end side of the insertion portion 64 and protrudes toward the substrate 61, and is locked to the upper end of the elastic leg portion 65. It has an operation arm portion 66 that is connected through a step portion 66 and is located on the substrate 61 side and extends in the lateral direction. The second locking portion 63 is bowl-shaped and has a pair of engaging piece portions 68 connected to both sides of the distal end of the insertion portion 67. The clip 60 described above is used when the upper panel 69 is attached to the lower panel 70 with a space therebetween, and for example, the second locking portion 63 is inserted and engaged with the attachment hole 70a of the lower panel 70. It is attached with. Thereafter, when the insertion portion 64 is inserted into the attachment hole 69a and brought close to the substrate 61, the upper panel 69 is locked at the locking step 66 with the swinging of the elastic leg portion 65. The locked state is released by pushing the operating arm portion 66 in the direction of the arrow and swinging the elastic leg portion 65 in the diameter reducing direction as shown in FIG. For this reason, in this clip 60, the upper panel 69 can be removed easily, and the latching with respect to the lower panel 70 is forcibly released from the state and collected.

  The above-described clips 50 and 60 are made of a single member, maintain a design fixing force with respect to the panel, and can be further unlocked. However, there are problems from the following points. Yes. That is, in the conventional structure, since the engaging leg and the elastic leg use elastic deformation, even if the fixing force is increased, if the board receives an excessive external force in the direction away from the mounting hole, that is, in the pulling direction, it is locked. There is a risk of being released. Further, since the clip 50 is configured to push the operation piece 54 into the notch 56 of the substrate 51, for example, if the notch 56 is clogged with dust or the like, the release operation cannot be performed. In the clip 60, after the upper panel 69 is removed from the first locking portion 62, the locked state with respect to the lower panel 70 cannot be easily released.

  The object of the present invention is to solve the above-described problems, and to ensure securing and locking force and securing operability for the panel, and in particular, the substrate is subjected to excessive external force in the pulling direction. Also, it is possible to improve the reliability by disabling the locking.

The invention according to claim 1 includes a board and an engagement leg, and the engagement leg is inserted into and engaged with the mounting hole of the panel and is locked to the panel. The locked state is the end of the engagement leg. In the easily dismantled clip that is released by operating the side, the engaging leg portion has a hollow-shaped space portion and a clearance portion in which a part of the space portion is enlarged in diameter, and the upper end side is unlocked. The board is connected to the board via an operating bridge part, and the board is provided with a latch release restriction corresponding to the protrusion part loosely inserted into the space part and the escape part. It is characterized by having a bulging portion for use.
The clip structure described above enables the engagement leg portion to be released from the panel mounting hole when the engagement leg portion is in the locked state and is released from the panel mounting hole by swinging in the reduced diameter direction by pushing the bridge portion. At the same time, when the substrate is displaced by receiving an excessive external force in the pull-out direction, the protruding portion and the bulging portion that are loosely inserted in the hollow portion also move in the same direction, so that the bulging portion is relatively smaller than the large-diameter flank portion. It shifts to the space part which became, and the displacement to the diameter reduction direction of an engagement leg part is controlled, and it becomes impossible to cancel | release latching by it.

The invention of claim 2 specifically specifies the above-mentioned invention along the examples of FIGS. 1 to 5, the same as the above-mentioned preconditions, and the engagement leg portion includes a hollow space portion and An escape portion having a part of the space having a large diameter, a bridge portion for unlocking operation connected to the upper end side and extending laterally, and an elastic piece protruding from the bridge portion and press-contacting the panel And the board is provided for holding and holding the article, and a protrusion for loosely inserting into the space and the relief portion provided in the protrusion corresponding to the escape portion. And a bulging portion.
In the above clip structure, in addition to the above-described operation, the engagement leg portion is made relatively long due to the presence of the elastic piece portion so that the projection portion can be easily arranged, or the displacement of the elastic piece portion is used to engage the panel with the engagement leg. This makes it easy to stabilize the locking force of the part.

  Claims 3 and 4 specify details of each of the above inventions. That is, in the third aspect, the gap between the clearance portion of the space portion and the bulging portion is set to be larger than the engagement margin of the engagement leg portion with respect to the mounting hole of the panel in the locked state. It is the composition which is. This is because, for example, the bridge portion can be pushed to securely release the engagement leg portion. On the other hand, according to a fourth aspect of the present invention, there is provided a hinge portion that is provided on the bridge portion and allows the bridge portion to swing and displace in the direction of reducing the diameter of the engagement leg portion. This facilitates the displacement of the bridge portion with the hinge portion as a fulcrum, so that the operability at the time of releasing the lock is improved.

(A) In the invention of claim 1, not only the clip is unlocked and recovered by the pushing operation of the unlocking bridge portion, but also the clip (substrate) is displaced in the same direction by receiving an external force in the pulling direction. When this occurs, the bulging portion enters the hollow portion that is relatively smaller than the large-diameter escape portion, and the displacement of the engagement leg portion in the diameter-reducing direction is restricted, so that the engagement cannot be released. For this reason, the invention clip can reliably prevent inadvertent unlocking while maintaining the fixing force or locking force with respect to the conventional product, thereby improving the reliability.
(A) In the invention of claim 2, in addition to the above effects, for example, even if the article is long, it can be stably held on the panel by the elastic displacement of the elastic piece part, or the engagement leg part with respect to the panel mounting hole It prevents rattling and stabilizes the locking force so that the degree of freedom in design can be expanded.
(C) In the invention of claim 3, the locking can be reliably released. According to the invention of claim 4, the operability at the time of releasing the lock can be improved.

  The best mode of the present invention will be described with reference to embodiments of the drawings. In the drawings, the first embodiment shown in FIGS. 1 to 4, the second embodiment shown in FIG. 5, the third embodiment shown in FIG. 6A, and the fourth embodiment shown in FIG. 6B are shown. In each Example, since the principal part is the same, the same code | symbol is attached | subjected to the same or similar site | part. In the following description, after describing the outline of the whole, the configuration of the main part is clarified by each embodiment.

(Summary) Easy dismantling clips (hereinafter abbreviated as clips) 1, 4, 5, and 6 of the respective embodiments are molded products in which the substrate 2 and the engaging leg 3 are integrally formed, and are shown in FIG. As described above, the engaging leg 3 is inserted into and engaged with the panel mounting hole 10a and the like and locked to the panel 10, and the locked state can be released by operating the end side of the engaging leg 3. In particular, the engaging leg 3 forms a hollow-shaped space 33 and a clearance 33a in which a part of the space 33 is enlarged in diameter, and the upper end side is a bridge for unlocking operation. It is connected to the corresponding portion of the substrate 2 via the portion 35, and the latch provided on the protruding portion 25 corresponding to the protruding portion 25 and the escape portion 33a in which the substrate 2 is loosely inserted into the space portion 33. A bulging portion 26 for release restriction is formed. Then, from the state in which the engaging leg 3 is inserted and locked in the mounting hole 10a or the like, the locking is released with the swing in the reduced diameter direction by the pressing operation of the bridge portion 35, and at the same time, the substrate 2 is pulled in the removal direction. When displaced by receiving an excessive external force, the projecting portion 25 and the bulging portion 26 are also displaced in the same direction, and the bulging portion 26 moves from the escape portion 33a to the space portion 33 in the direction of diameter reduction of the engagement leg portion 3. By restricting the displacement, the unlocking is disabled. These are common in each embodiment. The clip material is made of resin, but may be other than resin. The “panel” is used in a broad sense including not only a plate member but also a plate portion such as a housing or a case. In addition to the object holding of the first and second embodiments, the application may be for mounting the panel illustrated in FIG. 6 to another panel.

(First Embodiment) FIGS. 1 (a) to 1 (c) are clip operation views, FIG. 2 (a) is a schematic external view of the clip, and FIG. 2 (b) is a protrusion and a bulging portion on the clip substrate side. Is shown. FIGS. 3A and 3B are a front view and a rear view of the clip, and FIGS. 4A and 4B are a left side view of the clip and a cross-sectional view taken along the line AA in FIG. . In this clip 1, the substrate 2 is mainly composed of a generally U-shaped portion 20, a lid portion 23 connected to one side of the U-shape, an engaging portion 21 provided on the other side of the U-shape, And a projecting portion 25 projecting downward from the U-shaped intermediate portion. The engagement leg portion 3 is substantially U-shaped, and the lower end portion 30, the maximum diameter engagement portion 31, and the upper end portion 32 define a hollow portion 33 and a relief portion 33a below the hollow portion 33, and upper end portions on both sides. 32 is connected to a corresponding portion of the substrate 2 via each bridge portion 35 connected to the base plate 32.

  The substrate 2 is formed thick and is given rigidity. Inside the portion 20, a single or a plurality of rods or linear members 8 (peripheral portions thereof) are accommodated. The engaging portion 21 forms a hole portion that is vertically penetrated on the other side of the portion 20. A locking claw 21a is provided at the upper edge corresponding portion of the hole. The lid portion 23 is a flat plate having a size corresponding to the opening of the portion 20, and is connected to one side of the portion 20 via a hinge portion 22. The lid portion 23 is provided on the free end side and is inserted into the hole portion. A substantially V-shaped insertion portion 24. Then, the lid 23 is switched between the open position of FIG. 3 rising from the portion 20 and the closed position of FIG. 2 that rotates around the hinge portion 22 to close the inside of the U shape. The linear member 8 is taken in and out of the portion 20 at the open position of the lid portion 23. When the lid portion 23 is rotated in the closing direction via the hinge portion 22, the corresponding portion of the insertion portion 24 is locked (locked) to the locking claw 21 a at the closed position. The protrusion 25 has a flat plate shape that is inserted into the hollow portion 33 of the engagement leg 3 with a margin. The lower end of the protrusion 25 has a tapered shape 25 a and has a bulging portion 26. The bulging portions 26 are respectively provided as substantially semicircular shapes on the left and right sides of the lower end side of the protruding portion 25.

  The engaging leg 3 is symmetrical and has a wall thickness that can be elastically displaced. The lower end 30 is formed in a tapered shape so that it can be guided to be inserted into the mounting hole 10a. Inside this, an escape portion 33a having a diameter larger than that of the hollow portion 33 is provided. The escape portion 33a is set to have an inner diameter that maintains a predetermined gap between the bulging portions 26 of the projection portion 25. The engaging portions 31 on both sides are locked to the lower hole edge of the mounting hole 10a when inserted into the mounting hole 10a together with the lower end portion 30 while being elastically displaced. The upper end portions 32 on both sides extend substantially in parallel to form a hollow portion 33 that communicates with the escape portion 33a. The gap between the hollow portions 33 is set to be approximately the same as the dimension between the two bulging portions 26. Therefore, in this structure, when the bulging portion 26 enters the hollow portion 33 from the escape portion 33a as shown in FIG. Make it maintainable.

  The bridge portion 35 includes a pair of horizontal portions 36 connected to the upper end portions 32 on both sides, and an upright portion protruding substantially vertically from each horizontal portion 36 and connected to both sides of the substrate 2 via hinge portions 39. 37. As shown in FIG. 3, each horizontal portion 36 extends laterally long at a predetermined interval with respect to the intermediate portion of the substrate 2, and the elastic piece portion 38 is inclined downward from a position approaching the upper end portion 32. It is protruding. Each elastic piece portion 38 is inclined so as to move away from the engagement leg portion 3 as it goes down, and the lowermost end is set so as to sandwich the panel 10 with the engagement portion 31 as shown in FIG. Of each standing portion 37, the lower side has a plate width dimension larger than that of the portion 20 of the substrate 2 and the horizontal portion 36, and is formed to be easier to press from the outer surface. The plate width dimension is made smaller toward the upper side and is connected to a lateral projecting portion 20a projecting on the outer surface of the corresponding portion of the portion 20 via a thin-walled hinge portion 39. For this reason, when each standing part 37 is pressed in the direction of the arrow in FIG. 1A, the bridge part 35 elastically displaces the horizontal part 36 and the engaging leg part 3 upward with the hinge part 39 as a fulcrum. The dimension between the engaging portions 32 can be reduced.

  Next, an application example of the clip 1 will be outlined with reference to FIG. In this example, it is assumed that the linear member 8 is supported along the panel 10. Usually, a plurality of clips 1 are attached to the panel 10, and the linear member 8 is supported by the plurality of clips 1. The Fig.1 (a) has shown the case where the clip 1 is attached to the panel 10, and the case where the clip 1 is collect | recovered after attachment. When the clip 1 is pressed from the state in which the lower end 30 is inserted into the panel mounting hole 10a, the engaging leg 3 passes through the mounting hole 10a while reducing the size between the engaging portions 32 in a reduced diameter. At the same time as the passage, the initial shape is restored to the locked state shown in FIG. That is, in the clip 1, the elastic piece portions 38 on both sides are in pressure contact with the panel 10, and the clip 1 is between the engagement portion 31 press-engaged with the lower edge of the mounting hole 10 a and the lower end of the elastic piece portion 38. Are held in a state where the panel 10 is sandwiched between them.

  When the clip 1 is removed from the panel 10 and collected, that is, when the locked state is released, the standing portions 37 of both the bridge portions 35 are pressed in the direction of the arrow in FIG. Then, the clip 1 is mounted in order to reduce the size between the engaging portions 32 while the bridge portion 35 elastically displaces the horizontal portion 36 and the engaging leg portion 3 upward with the hinge portion 39 as a fulcrum. It can be easily pulled out from the hole 10a. In this structure, the gap between the engagement leg portion 3, that is, the large-diameter relief portion 33 a of the space portion 33 and the bulging portion 26 of the projection portion 25 is engaged with the panel mounting hole 10 a in the locked state. The engagement leg portion 3 is set to be larger than the engagement allowance so that the diameter of the engagement leg 3 is not restricted by the presence of the protrusion 25 and the bulging portion 26 when the lock is released. Further, in this structure, the plate width of the standing portion 37 is set larger than the horizontal portion 36 and the portion 20 so that the pushing operation at the time of releasing the lock can be performed smoothly, or the engagement leg portion 3 is provided with the elastic piece portion 38. Therefore, it is easy to deform right above, and the operability at the time of releasing the lock is improved.

  FIG. 1C shows a state in which the clip 1 holds the linear member 8 and receives an external force in the removal direction via the linear member 8 or the like. When the external force in the direction of the arrow increases, the clip 1 is elastically deformed so that the substrate 2 moves away from the panel 10 via the hinge portion 39, and the protrusion 25 and the bulging portion 26 are also moved in the same direction as the substrate 2 is deformed. Displace to lift. The bulging portion 26 enters the space portion 33 that is relatively narrow from the large-diameter escape portion 33a due to the displacement. For this reason, the engagement part 31 of the largest diameter among the engagement legs 3 is restricted from being displaced in the reduced diameter direction by the bulging portion 26 and is in an unlocked state. In this structure, as the external force in the removal direction increases, the bulging portion 26 moves up the space 33 and the regulating force of the bulging portion 26 is increased, thereby reliably preventing inadvertent detachment of the clip 1. enable.

(Second Embodiment) FIG. 5 (a) is a schematic external view of a clip corresponding to FIG. 2 (a), and FIG. 5 (b) is a view showing a use state of the clip corresponding to FIG. 1 (b). The clip 4 is an example of the clip 1 in which the bar of the substrate 2 or the holding structure for a linear member is modified. This structure is the same as that of the first embodiment in that the substrate 2 is formed in a substantially U-shape, but the U-shaped both pieces 27 are set long and are vertically There are sandwiching pieces 28 and 29 provided to face each other in two stages. The upper sandwiching pieces 28 extend obliquely downward with a relatively steep slope, and the lower sandwiching pieces 29 are formed in an arc shape only at the distal end side. Then, when the linear member 9 is pushed in between the holding pieces 28 while elastically displacing the holding pieces 28 downward, as shown in FIG. 5B, the lower holding piece 29 and the upper holding piece 28 It is elastically supported between. Therefore, this clip 4 has an advantage that it can be supported and operated with one touch without requiring a lid opening / closing operation like the above-described clip 1 when holding the rod or the linear member 9. Since other than this is the same as the first embodiment, the description thereof is omitted.

(Third Embodiment) A clip 5 shown in FIG. 6A shows a structural example in which the upper panel 12 is fixed in close contact with the lower panel 11 as in FIG. That is, the clip 5 is formed when the substrate 2 is formed in a simple flat plate shape in the clip 1 and is used when the upper panel 12 is overlapped with the lower panel 11. When the engaging leg 3 is inserted and engaged with the mounting holes 12a and 11a, the panels 11 and 12 are locked while being sandwiched between the engaging portion 31 and the elastic piece 38. As in the case of the clip 1, when the both bridge portions 35 are pushed in the locked state, the horizontal portion 36 and the engagement leg portion 3 are elastically displaced upward with the hinge portion 39 as a fulcrum. Since the dimension between 32 is reduced, it can be easily pulled out from each mounting hole 11a, 12a. Since other than this is the same as the first embodiment, the description thereof is omitted.

(Fourth Embodiment) A clip 6 shown in FIG. 6B shows an example of a structure in which an upper panel 14 is fixed to a lower panel 13 at a predetermined interval as in FIG. That is, in the clip 6, the substrate 2 has protrusions 25 with bulging portions 26 in the vertical direction with respect to the clip 5, and the engagement leg portions 3 are also provided on the upper and lower sides of the substrate 2. The relationship between the projecting portion 25 positioned above and below and the corresponding engagement leg portion 3 is the same as that in the first embodiment. When the upper panel 14 is attached to the lower panel 13 with a space therebetween, the above clip 6 is, for example, first inserted and engaged with the lower engaging leg 3 in the attachment hole 13a of the lower panel 13 to The lower panel 13 is held between the engaging portion 31 of the side engaging leg portion 3 and the corresponding elastic piece portion 38 in a state of being sandwiched. Thereafter, when the upper panel 14 inserts the upper end 30 constituting the upper engaging leg 3 into the mounting hole 14a and is pressed toward the panel 13, the upper panel 14 corresponds to the engaging portion 31 of the upper engaging leg 3. The upper panel 14 is sandwiched between the elastic piece portion 38 and the elastic piece portion 38 to be locked. In this structure, both the locking states of the lower panel 13 and the upper panel 14 can be easily released by pressing each bridge portion 35 of the clip 6 directly or using a tool. Since other than this is the same as the first embodiment, the description thereof is omitted.

  As described above, the present invention can be variously deformed and expanded except for the main part. Even in this case, the unlocking operation can be easily performed, and inadvertent unlocking can be reliably prevented. For this reason, the invention clip not only can increase the fixing force to the panel side while maintaining the simplicity of a single member, but also can be reliably removed from the mounting hole and recovered during recovery operations such as dismantling.
