Description

[Detailed description of the invention] [Industrial field of application] This invention is a method for assembling plate-like members such as panels, by preparing a temporary mounting clip on one of the members and using it as needed. Regarding the improvement of a clip in which the same clip is attached to the other member to make the permanent fastening, more specifically, it is possible to make temporary fastening and permanent fastening by using an elastically deformable engagement piece provided on the insertion leg of the clip. The present invention relates to the provision of a mounting clip which is intended to reduce the assembly effort and the cost of mounting parts.

[Prior Art] There are various types of clips that have been used to attach panels of this type. Resin push-in clips, such as the one shown in the figure, are increasingly being used.

This push-in clip is used to attach two or more panels stacked on top of each other, and
After stacking the panels in sequence so that the mounting holes of the panels to be assembled coincide with each other, insert the panels into the mounting holes from the free end 101a side of footnote 101,
The edge of the mounting hole is locked by engagement convexes 102 to 102 provided in multiple stages on the circumferential surface of the clip.

[Problem to be solved by the invention] However, in such push-in clips, in order to precisely position the mounting holes of the panels to be attached one by one, the panels are moved appropriately and the clips are held in separate hands, and this positioning is done by holding the clip separately in one hand. It is necessary to insert the clip into the hole in the overlapped panel with the panels stacked together. For this reason, the assembly work is complicated and inefficient, and problems such as loss of clips are likely to occur in terms of parts management.

Also, a large hole is provided in the panel to be installed through which the clip is inserted, and the clip is inserted loosely into the insertion hole of this panel, and the clip is loosely inserted into the panel on the side of the mounting body. Even when pushing the clip in and locking the protrusions 102 to 102 of the clip on the edge of the hole in the panel, it is difficult to confirm the position of the mounting hole in the panel located on the lower side, similarly to the above case, and it is difficult to check the position of the mounting hole in the panel on the mounting body side. There is an inconvenience that the clip may fall off and be lost before it is inserted.

For this reason, various attempts have been made to provide a separate temporary fastening structure for the push-in clip, attach this clip in a temporary fastening state to one of the panels to be assembled, and then insert the clip into the panel to be assembled for final fastening.

However, in conventional mounting clips of this type, the temporary fastening means and the permanent fastening means are often provided separately, and the cost tends to be relatively high due to the molding surface or the number of parts.
Moreover, unnecessary gaps were often created between the assembled panels.

The mounting clips for panels etc. related to this invention are as follows:
This clip was proposed in view of the inconveniences of the conventional push-in clips, and is particularly meaningful as a means of attaching an insulator to the bonnet of a car, a trim board, a lining finisher in a trunk, etc. This method allows you to use the clip's original engagement piece, which is a means of permanently fixing panels, etc., and attach the used clip to the panel, etc. to be attached in advance in a temporary fixing manner. This makes the final fastening operation easier and smoother.
In addition, the clip uses only one component and has an extremely simple structure.

[Means for solving the problem] The mounting clip A for panels, etc. according to the present invention is as follows:
For this purpose, the structure is made up of a head 1, an insertion leg 2 integrally projecting from the head 1, and a distal end of the insertion leg 2 running approximately parallel to the head 1. The engaging piece 3 is configured to have an extending engaging piece 3, and the engaging piece 3 is an elastic piece-like bendable piece having at least two sides, and extends toward the base of the leg portion 2. (With or without a hinge)
It is said to be bendable and elastically deformable. One or more engaging protrusions 4 are formed on the outer surface of the engaging piece 3 bent toward the base side of the leg portion 2, that is, the surface not facing the head 1. It is provided in a direction substantially perpendicular to the direction in which the mating piece 3 is inserted.

[Function] The clip for attaching a panel, etc. according to the present invention can be mounted by inserting the leg part 2 of the clip A into the mounting hole b of the panel B of the insulator or the like to be attached with the above structure. The engaging piece 3 is bent toward the base of the leg portion 2 by the edge of the hole b.

Then, by passing the free end of the engaging piece 3 through the hole edge of the hole b of the panel B, it is returned to its expanded original state again, and as shown in FIG. Insert panel B into the hole and use it as a temporary fastener, or insert the engaging piece 3 of clip A halfway into hole b of panel B as shown in Fig. 6, and apply its elastic force. Use this to make a temporary attachment.

In such a state, the engaging piece 3 of the leg 2 is inserted by pushing the leg 2 of the clip A from the top into the mounting hole b' provided on the surface of the panel B' where the bonnet etc. is to be attached. , 3 are again narrowed by the edge of this hole b', and the panels B and B' are inserted until they come into close contact with each other.

At this time, the hole b' in panel B' is made smaller in diameter than the hole b in panel B, and when the engaging piece 3 is sufficiently bent toward the base side of the leg part 2, this engaging piece 3
The engagement protrusion 4 on the tip side of the panel B'
If the diameter of the hole is such that it is located inside b' and locks the hole edge of hole b', then panels B and B' will be damaged as if the bent part of the engaging piece 3 of clip A was damaged. It has the feature of being able to sufficiently maintain a mutually attached state even in the case of

[Embodiment] A typical embodiment of the clip for attaching a panel or the like according to the present invention will be described below with reference to the accompanying drawings.

First, to explain the typical embodiment shown in FIGS. 1 to 7, the clip A has a flat disc-shaped head 1 as a seat, and a curved inner central part of the clip A. It consists of a protruding leg 2 and a pair of engagement pieces 3 extending from the distal end of the leg 2 substantially parallel to the head 1, and has the elasticity required for locking. A typical example is a plastic product with deformable properties.

Next, the leg part 2 has a recess 6 into which the protruding convex part 5 provided on the leg part 2 side of the engaging piece 3 bent toward the base side of the leg part 2 is inserted, and the apex part is the tip. 2a is made into a smooth bulging shape, and the panel
This creates a better insertion surface for B′.

Further, the engagement piece 3 has an elongated plate shape that extends symmetrically in the left-right direction so as to sandwich the top 2a of the leg 2, and the tip side of the engagement piece 3 is extremely close to the base side of the leg 2. It is shaped like a wing with a gentle, almost horizontal slope to prevent it from tilting.

Further, the portion of the leg 2 located on the mounting base side of the engagement piece 3 is formed into a concave shape 7, so that the engagement piece 3 is configured to be easily bent toward the base side of the leg 2. .
Then, it engages with the surface opposite to the side facing the head 1 corresponding to the upper surface side of the engaging piece 3, that is, the outer surface of the engaging piece 3 that is bent toward the base side of the leg portion 2. The protrusions 4 to 4 are provided with raised protrusions 5 on the surface opposite to the surface on which the protrusions 4 to 4 are provided, that is, on the inner surface of the engagement piece 3 that is bent toward the base side of the leg portion 2. is provided.

Next, the engagement protrusions 4 to 4 are multi-staged between the distal end side and the base side of the engagement piece 3, and are bent in the width direction of the engagement piece 3, that is, toward the base side of the leg portion 2. Piece 3
The engagement protrusion 4 is formed in a direction substantially perpendicular to the insertion direction of the engagement piece 3, and the distal end side thereof is at a right angle or an acute angle shape, and the base side thereof is an obtuse angle shape. An insertion surface 4a and a locking surface 4b are created on the raised surface 4.

The raised convex portion 5 is such that the engaging piece 3 of the clip A is
An inclined surface 5a is provided on the distal end side of the engagement piece 3 so that the engagement piece 3 can be easily inserted into the recess 6 of the leg 2 when the leg 2 is sufficiently bent toward the base side. Also, the seventh
As shown in the figure, when the protrusion 5 of the engagement piece 3 is bent by the hole edge of the hole b' of the panel B' until it is completely fitted into the recess 6, the engagement piece 3 is bent. Even if the panels B and B' are cut or broken at the bending position, the state of attachment between the panels B and B' will be maintained as is, and as long as the protrusion 4 is not deformed or damaged, the panels B and B' will remain intact. It is attached by clip A.

Next, engagement protrusions 8 to 8 are provided in multiple stages in the vertical direction of the leg section 2 on the opposing sides of the leg section 2 and on the surfaces that are sandwiched by the engagement pieces 3, 3. and the protrusions 8 to 8 are configured to be engaged with the hole edge of the hole b' of the panel B', which is perpendicular to the hole edge with which the engaging pieces 3, 3 engage. Further, the base side of the leg portion 2 is formed into a recess 9, and the tip of the engaging piece 3 can go in and out in the direction of the recess 9.

The mounting clip of the embodiment described above has a unique structure as described above, and is temporarily fastened to panel B and then permanently fastened to panel B'.
Panel B has a slightly larger mounting hole b through which the protrusion 4 of the engaging piece 3 passes through while the engaging piece 3 is narrowed toward the base side of the leg 2 and is narrowed toward the side of the deformed leg 2. is provided on the panel B', and the engagement piece 3 is similarly flexed sufficiently toward the base side of the leg 2, and the protrusion 4 is of a size that is engaged in an elastic contact state. A mounting hole b' is provided. Further, the hole diameters of the mounting holes b and b' of the panels B and B' corresponding to the above-mentioned engaging protrusions 8 to 8 provided on the leg portion 2 are also determined under similar conditions.

In this state, as shown in FIGS. 4 and 6, by pushing the clip A into the hole b of the panel B from the side of the top 2a of the leg 2 of the clip A, the engaging pieces 3, 3 are removed. is from the position of the recessed part 7 to the leg part 2.
The insertion surface 4a of the protrusion 4 is bent toward the base side of the protrusion 4.
is inserted by sliding over the edge of hole b. In this case, as shown in FIG. 5, there is a case where the clip A is temporarily attached to panel B by pushing the clip A into panel B until the insertion surface 4a slides over the edge of hole b and is inserted, and there is a case where the clip A is temporarily fastened to panel B as shown in FIG. In some cases, the clip A is pushed halfway into the hole b of the panel B so that the clip A is elastically temporarily attached to the panel B. In addition, in order to smoothly attach the panel B, when the engagement piece 3 is bent toward the base side of the leg 2, the panel B is inserted between its tip and the head 1.
I try to leave a gap that is at least as thick as .

In this manner, the clip A temporarily attached to the panel B in the state shown in FIG. 5 or 6 is pushed into the hole b' of the panel B' to be overlapped with the panel B. This pushing is done in each hole b of panels B and B'.

This is done while receiving appropriate impact depending on the thickness and width of the engaging piece 3 that is bent into the base side of the
The protrusion 4 of the engaging piece 3 springs toward the edge of the hole b' of the panel B' and supports the peripheral plate portion inside the hole b'.

FIG. 7 shows a typical example in which such panels B and B' are attached by clip A in an overlapping state, and the edge of hole b' of panel B' is located between the protrusions 4 and 4 of engagement piece 3. However, the protrusions 5 of the engaging pieces 3 are inserted into the recesses 6 of the legs 2 of the clip A and are elastically supported.

In such a typical example, even if the engaging piece 3 is cut off or broken from the leg part 2 as already mentioned above, the panels B and B' are held together by the clip A.
It will continue to be supported as is.

The embodiment shown in FIG. 8 shows a case in which only one protrusion 4 is provided on the engagement piece 3, and this protrusion 4 is provided as one or more appropriate strips.

The embodiment shown in FIG. 9 shows an example in which the hole b of the panel B can be set sufficiently large, and the diameter of the hole b of the panel B is determined by the diameter of the convex portion 5 of the engaging piece 3.
By making the hole diameter match the respective surfaces of the inclined surfaces 5a, 5a, when inserting the clip A into the panel B', the clip A can be positioned at the center of the hole b of the panel B, and the overlapping panels

Moreover, the embodiment shown in FIG.
On the other hand, elastic engagement pieces 10, 10 having no protrusions 4 to 4 on the side perpendicular to this are attached to the top 2a of the leg 2.
It is designed to protrude from the side towards the side.

These engaging pieces 10, 10 are connected to holes b in panels B, B',
When b' has a long diameter side and a short diameter side, such as a rectangle or an ellipse, it has the advantage that the temporarily fastened state of the clip A can be maintained on either side.

Note that although the illustrated example shows a state in which the engaging piece 3 is in close contact with the surface of the leg portion 2, the diameter of the hole b' is not necessarily adjusted so as to narrow the engaging piece 3 to such a state. The locking surface 4 of the protrusion 4 is attached to the hole edge of the hole b' of the panel B' by utilizing the elasticity of the engaging piece 3 without making it narrow.
It is also possible to apply b.
