Description

[Detailed description of the invention] [Field of industrial application] This invention is applicable to the mounting of parts on the body of an automobile, such as when fixing a plate-shaped mounting piece of a part to a plate part of the body. This invention relates to a coupling clip that can be effectively used in cases where two objects are overlapped and fixed together.

[Prior Art] Many proposals have been made for clips for joining plates together, and a wide variety of types of clips have been commercialized.

Among these many types of clips, the present invention particularly focuses on a combination type of joint consisting of a clip main body equipped with expandable leg pieces, and a pin member that expands the leg pieces by fitting and pushing into the clip main body. Regarding clips.

More specifically, the clip of the present invention achieves the combination of both by inserting the pin member into the insertion hole of the main body of the clip, and when the pin member is further inserted in this state, the leg pieces are expanded, and this expansion causes A type of engagement clip called a push rivet, which connects the plates (panels) together, and when the pin member is further pushed in, the legs release the expansion and contract in diameter, thereby releasing the mutual connection between the plates. Regarding the improvement of

An example of this push rivet type coupling clip is disclosed in Japanese Patent Publication No. 13144/1983.

This conventional coupling clip (coupling clip) is made by inserting a pin into the clip body and then pushing it in the first stage to push out the protrusion on the leg with the large diameter part provided on the shaft and expand the leg. The overlapping plates are fixed together between the tsuba (head) of the pin, and then when the pin is pushed in, the large diameter part is shifted from the protrusion, the leg part is released, and it is pulled out from the insertion hole provided in the plate. It is constructed so that it can be removed, and the plates can be joined and released by pressing the pin in one direction, making it a convenient clip for use in places where it is necessary to release the fixation.

However, when this clip fastens the board,
For example, when fixing a plate member of a part to a plate part of an automobile body, it is extremely difficult to do so because the main body of the clip is inserted through the mounting holes drilled in the plates and then the pin is simply inserted. Although it is simple, it becomes difficult if you insert the clip in this state while aligning the mounting holes of the plates and then try to press-fit the pin.

For example, when parts are attached and fastened from below on an automobile assembly line, the work space is small, and in this case, there is work to support the parts, work to align them, and work to attach the clips. The task of inserting the pin into the mounting hole and then pushing the pin in is a very troublesome task, and it may become practically impossible to use the clip by press-fitting the pin.

[Problems to be solved by the invention] In view of the above-mentioned defects in the coupling clip related to the combination of the clip main body and the pin, the present invention solves the following problems:
This device was devised to solve this problem, and its purpose is to provide a locking means that allows a joining clip to be latched in advance to a mounting hole provided in one of the boards to be joined, so that when joining the boards, By temporarily fixing a clip to this mounting hole in advance, this allows you to support the board (component) to be mounted and align the mounting hole during the actual fixing work, eliminating the need to hold the clip. This makes it easier to push the pin in.

[Means for Solving the Problems] That is, the present invention was devised based on the above-mentioned purpose, and its features include a brim-shaped head;
a plurality of expandably divided leg pieces that hang down from the lower surface of the head and have protrusions on the inner surface of the tips; and an insertion hole that extends vertically from the upper surface of the head and extends through the center of the leg pieces; a clip main body having a length that penetrates the insertion hole, an enlarged part provided in the middle of the length with the diameter of the insertion hole as the limit, and a first clip main body provided before and after the length sandwiching the enlarged part. , a pin member having a second contracting portion and an elastic locking piece extending from the front end toward the rear end and keeping the free end in an expanded state at all times; The first leg is inserted into the fitting hole and the protrusion of the leg is fitted into the first reduced portion to be coupled, and at the same time the elastic locking piece is made to protrude outward from between the legs so that it can be locked. 1 posture, a second posture in which the pin member is further pushed in so that the enlarged part faces the protrusion of the leg piece, and the leg piece is expanded; and a second posture in which the pin member is further pushed in and the protrusion of the leg piece is exposed in the second reduced part. An object of the present invention is to provide a connecting clip which can be sequentially changed to a third posture in which the leg piece is received and the leg piece is contracted.

[Operation] The above-mentioned connecting clip of the present invention is maintained in the connected state in the first attitude by inserting a pin member molded separately from the front end into the insertion hole of the main body of the clip. When using the clip, first insert the clip-based leg pieces into the mounting holes provided on the plate (component) to be attached, and then bend the elastic locking pieces that protrude between the leg pieces. Temporarily fastened by hooking the free end to the opposite side of the board, then placing this board against the other board,
Insert the main body of the clip into the mounting hole drilled in this,
When the mounting holes are aligned, press the rear end of the pin member that protrudes from the upper surface of the head of the clip main body and push it into the fitting hole so that the enlarged part in the middle of the length faces the protrusion of the leg piece, and take the second position. By doing so, the plates can be fixed together between the expanding leg pieces and the head.

Then, when the pin member that has expanded the leg piece is further pressed and pushed into the fitting hole, the second contracting part faces the protrusion of the leg piece and is received, changing to the third posture and contracting the leg piece. Since the diameter is increased, the bond between the plates is released.

The coupling clip of the present invention is constructed and used as described above, and will be explained below based on examples to further clarify this.

[Example] Figure 1 is a perspective view of the coupling clip of the present invention in an exploded state with the clip main body 1 and pin member 2 separated, and Figure 2 is a perspective view of the coupling clip of the present invention immediately before coupling the two plates A and B. Figure 3 shows the temporarily fastened state before joining the two plates, Figure 4 shows the joined state, and Figure 5 shows the released state after joining, and Figure 6 shows the joint of the present invention. An enlarged bottom view of the clip is shown.

The clip main body 1 includes a collar-shaped head 3, a leg piece 5 that hangs down from the lower surface of the head and is divided into four parts by a vertical cross-shaped slit 4 cut from the leg end.
The head 3 integrally has a fitting hole 6 vertically bored through the center of the leg piece from the upper surface thereof, and the fitting hole 6 is formed on the inner surface of each tip of the leg piece 5 so as to protrude inwardly. A projection 7 is provided which has a substantially reduced diameter.

On the other hand, the pin member 2 has a shaft whose diameter is limited to the diameter of the insertion hole 6, and an enlarged portion 10 is provided between the rear end portion 8 and the front end portion 9, which is approximately truncated and conical. A first reduction section 11 and a second reduction section 12 are provided at the front and rear. A pair of elastic locking pieces 13 are provided on the front end portion 9 and extend from the rear end surface portion facing the first reduced portion 11 toward the rear end portion 8 to enlarge the free end thereof. It is arranged to protrude outside the outer diameter of the portion 10.

The elastic locking piece 13 shown here is a thin airfoil-shaped piece, and its length is within the range of the length of the first reduced portion 11.

As shown in the figure, the clip main body 1 and the pin member 2 are individually molded from a synthetic resin material having the required elasticity, and after molding, the pin member 2 is inserted into the insertion hole 6 of the clip main body. It is assembled in.

Figure 1 shows the state in which these two members are separated,
From the front end 9 of the pin member to the insertion hole 6 for the main clip
It is assembled as shown in FIG. 2 by pushing it into place.

The assembly of both members is carried out by simply pushing the pin member 2. At this time, the pin member temporarily bends the elastic locking piece 13 and retreats to the first reduced portion 11, and the head of the clip main body 1 3, it is restored and its free end is made to protrude outside the leg through the slit 4 which cuts the leg 5.

FIGS. 3a and 3b show the first posture in which both members are connected, and the elastic locking piece 13
When the pin member 2 protrudes from the leg piece 5 through the slit 4, the protrusion 7 provided on the inner surface of the tip of the leg piece is inserted into the pin member 2.
This prevents the receiving pin member from falling off at the first reduced portion 11, and also returns the leg piece 5 to its original shape.

Now, when the connecting clip of the present invention assembled into one in this way is used to connect the two plates A and B, first the legs of the main body of the clip are inserted into the mounting hole a drilled in one of the two plates, A. The piece 5 is inserted, and along with this insertion, the elastic locking piece 13 that protrudes outside the outer peripheral surface is passed through, and by the restoration of this locking piece, it is temporarily fixed to one of the plates A.

After temporarily fixing one plate A, use the front end 9 of the pin member 2 protruding on the opposite side of this plate as a guide to find the mounting hole b of the other plate B, and align it therewith [Fig. 3 a , b], the plate B is brought into contact with one side of the plate A, and the tip of the leg piece 5 is connected to the front end 9 of the pin member.
and insert it into the mounting hole b.

With this insertion, when the tip of the leg piece 5 protrudes to the opposite side of the plate A, when the rear end part 8 of the pin member 2 is pressed, each protrusion 7 of the leg piece moves into the first reduced portion as the pin member enters. 11 to the enlarged part 10, and along with this movement, each leg piece 5 is expanded, and as shown in FIGS. The two plates A and B are firmly connected in a pinched manner.

At this time, in this embodiment, the rear end portion 8 of the pin member is aligned and integrated with the upper surface of the head portion 3 of the clip main body, and the protrusion 7 of each leg piece 5 is formed into an annular shape provided at the top of the enlarged portion 10 of the pin member. The expanded state can be stabilized by sliding it into the groove 14 of the tube.

In this way, the plates A and B can be fixed together in contact with each other, while the leg piece 5 receives the protrusion 7 on the enlarged part 10.
When the pin member 2 is expanded and the pin member 2 is further pressed so that the rear end portion 8 is inserted into the insertion hole, the projection 7 crosses the enlarged portion 10 and faces the second reduced portion 12, as shown in FIG. In this way, the leg pieces are released from expansion, restored to their original shape, and can be pulled out from the mounting holes a and b of both plates A and B as they are.

The coupling clip of the present invention is constructed and used as described above, and in particular, in its use, the pin member is pushed into the insertion hole of the main body of the clip to assemble it into one piece, and the plates to be coupled in this assembled state are It is convenient to connect the plates by inserting the leg piece into the mounting hole and pressing the pin member again. However, the connecting clip of the present invention does not require attachment of one plate when inserted into the mounting hole. By inserting the clip-based leg piece into the hole, the elastic locking piece 13 provided on the pin member can be locked and held in this mounting hole, so when actually joining the plates together, it is necessary to insert the clip itself. There is no need for support, and all that is required is alignment of the mounting holes and pressing of the pin member.

Now, Figures 7 to 11 and Figures 12 to 16 show two concrete examples in which the coupling clip according to the present invention is used as a fixing means for fixing a meter cluster C of an automobile to a safety pad D. A practical example is shown.

The embodiment shown in FIG. 2 shown in FIGS. 7 to 11 is a case where the clip main body 1 and the pin member 2 fitted thereto are circular, and the embodiment shown in FIGS.
In this embodiment, the substantially cross-sectional shapes of the leg piece 5 of the clip main body and the pin member for expanding the main leg piece are both rectangular. For convenience of explanation, the first
The same parts as in the first embodiment shown in FIGS. 6 to 6 are designated by the same reference numerals, and their explanation will be omitted.

First, the second embodiment is an example in which the vertical length of the clip is shorter than that of the first embodiment due to the location of use. The clip main body 1 and the pin member 2 are formed separately and assembled by pushing the pin member 1 into the insertion hole 6 of the clip main body as described above. This combination is the first reduced portion 11 of the pin member 1.
is in the first position facing the protrusion 7 of the leg piece 5, and the elastic locking piece 13 extending from the front end part 9 of the pin member projects outward from the slit 4 dividing the leg piece 5. The state is as follows.

Fig. 8 shows the coupling clip in this combined state, and when attaching the meter cluster C, insert the leg piece 5, which is the main part of the clip, into the mounting hole c opened in the meter cluster C. The locking piece 13 is hooked to the edge of the hole.

Fig. 9 shows the meter cluster c temporarily latched into the mounting hole c, and then the meter cluster c is attached to the safety pad D from below, and the leg piece 5, which mainly consists of a clip, protrudes upward. Find the mounting hole d provided in the safety pad as a guide, and insert the tip of the leg piece 5 into this mounting hole d. Thereafter, the rear end 8 of the pin member 2 protruding from the head 3 of the main body of the clip is pressed until it is flush with the upper surface of the head, and is inserted into the fitting hole 6.

Figure 10 shows this pressing completion state.
When the enlarged portion 10 of the pin member 2 faces the protrusion 7, the leg piece 5 expands, bites into the edge of the mounting hole d, and holds the meter cluster C and safety pad D between it and the head 3, which is mainly a clip. , it will stick.

Here, the mounting hole c of the meter cluster C is formed in two stages with different diameters, so that the head 3, which is mainly a clip, can be embedded therein to avoid protrusion from the surface.

With the clip of the present invention in which the meter cluster is attached in this manner, the expansion of the leg piece can be released by further pushing the pin member 2 into the fitting hole.

FIG. 11 shows the disengaged state, and the clip can be removed from the safety pad D while the clip remains attached to the meter cluster.

Next, in the third embodiment shown in FIGS. 12 to 16, the leg pieces 5 hanging down from the head 3 are a pair of plate-shaped leg pieces, and the insertion hole 6 has a rectangular cross section. This is a case where the pin member 2 has a rectangular cross section as well as a similar hole.

The clip in this embodiment is advantageously implemented when specifying the orientation of the plate to be attached by making the cross section rectangular, and is substantially the same as in the first and second embodiments.

The elastic locking piece 13 in this embodiment is made to protrude laterally from between the opposing leg pieces 5 (slit) when the pin member 2 is combined with the clip main body 1, and this locking piece is attached to the meter cluster C in a square shape. It is temporarily fixed by hooking it into the formed mounting hole c.

FIG. 14 shows this temporarily fixed state. Next, when the pin member 2 is pressed and the front end portion 9 is protruded from the tip of the leg piece 5, the leg piece opens due to the protrusion of the enlarged part 10, and the 15th As shown in Figures a and b, it bites into the mounting hole d of the safety pad, completing the mounting of the meter cluster in the same manner as in the second embodiment.

Figure 16 shows the pin member 2 to release the fastened state.
Push the fitting hole 6 deeply and insert the protrusion 7 into the second reduced part 12.
This shows the state in which the legs are contracted by accepting the .

[Effects of the invention] The embodiments illustrating the coupling clip of the present invention have been described above, and the clip of the present invention has an elastic locking piece 13 on the pin member, and when this locking piece is combined with the main body of the clip, it splits. When the leg piece is inserted into the mounting hole of the plate that protrudes outward from between the leg pieces, the latching clip can be temporarily held on the edge of the hole, so the meter cluster can be fixed to the safety part. When fastening two boards together, there is no need to support this connecting clip with your fingers; simply align the mounting holes and push in the rear end of the pin member, where the upper surface of the main head of the clip sticks out. The legs can be opened to complete the attachment.

In addition, during this fixing operation, the tips of the legs are left protruding from the mounting holes due to the temporary fixing of the coupling clips, making it extremely easy to align them with the mounting holes on the other plate. You can expect quick work.

In particular, the above-mentioned temporary fixing to the mounting hole using the elastic locking piece is more advantageous when the meter cluster described in the embodiment is attached to the safety pad from below.

Conventionally, in cases like this, after aligning the mounting holes, hold the attached plate with one hand to prevent it from moving, then insert a clip into the aligned mounting hole with the other hand and hold it. However, with the clip of the present invention, it is not necessary to hold the clip inserted into the mounting hole by the temporary fixing, and the rear end of the pin member is simply pressed. It is extremely easy to handle, as all you have to do is push it in by hitting it.

In addition, with the coupling clip of the present invention, by pushing the pin member used to expand the leg piece deep into the insertion hole, the leg piece can be unexpanded and unfastened from the mounting hole, making it easy to fasten the board. In this state, the pin member expands its elastic locking piece to prevent the plate from falling off from the mounting hole, so it will not be lost and the pin member can be returned to its original first position. This allows it to be used as is for refastening.

Incidentally, as explained in the embodiment, the number of leg pieces divided into a plurality of pieces may be four or two, and the number is not particularly limited, and the same applies to the elastic locking pieces. It is not limited to two. For the elastic locking piece, when in normal condition, it is necessary that the locking part is passed through between the leg pieces and protrudes outward from the leg piece, so that it always remains locked in the mounting hole of one plate. be.
