Description

[Detailed description of the invention] <Industrial application field> This invention relates to a holder that rotatably holds a rod with one end bent in a hole in a board. used.

<Prior Art> There are various proposals as a holder for this type of rod.

FIG. 16 shows a longitudinal cross-sectional view of the holder attached to the board. The holder 1 is made of elastic rubber or the like and is integrally molded, and has an annular groove on the outer periphery that fits into the edge of the hole 2 of the board P. 3, and has a through hole 4 in the center that penetrates vertically.

One end of the rod 5 held by this holder 1 is inserted into the through hole 4 of the holder 1, and the tip is bent into a crank shape to prevent it from coming off when inserted.
The upper bent portion 5a is supported by contacting the upper edge 1a of the holder 1, and the lower bent portion 5b is supported by contacting the lower edge 1b of the holder 1.

It also consists of a head with a circular flange that comes into contact with the surface of the board, and legs that extend downward from the bottom of the flange and are inserted and locked into holes in the board, and are continuous from the head to the legs. The legs have stepped shoulders for insertion into the holes of the board, a plurality of open end slots cut out from the lower end, and elastic fingers formed between the slots. A holding tool is known (Japanese Unexamined Patent Publication No. 13747/1983).

<Problems to be solved by the invention> However, in the former holder 1 shown in Fig. 1,
There was a problem in that the work of attaching the rod 5 to the substrate P and attaching the rod 5 to the holder 1 attached to the substrate P was extremely troublesome.

That is, in order to attach the holder 1 to the substrate P, the holder 1 must be deformed and forcefully pushed into the hole 2 of the substrate P. If too much force is applied when pushing, the holder 1 may pass through the hole 2. There was a risk that it would fall onto the back side of the board P. Further, since it is difficult to reliably fit the annular groove 3 of the holder 1 into the edge of the hole 2, the holder 1 may fall off after being attached.

On the other hand, in order to prevent the rod 5 from coming off from the holder 1, the tip must be bent into a crank shape, which makes insertion of the rod 5 extremely difficult.
Further, even after installation, there was a large play in the vertical direction with respect to the holder 1.

That is, in order to prevent the rod 5 from wobbling, each bent portion 5 of the rod 5 must be
a, 5b must engage the upper and lower edges 1a, 1b of the holder 1 as closely as possible. However, if the degree of freedom of the rod 5 in the vertical direction is reduced in this way, it becomes impossible to insert the rod 5, or it becomes extremely difficult to insert the rod 5.

In addition, the latter holder mentioned above (Japanese Patent Application Laid-open No. 13747-1983)
(No. 3), the presence of the slot improves the ease of inserting the rod, but depending on the direction in which the rod is inserted, the tip may hit the elastic finger, impairing insertion, or the elastic finger may face outward. When the rod is bent, the stepped shoulder on the outer surface touches the edge of the hole in the board, making it difficult to bend the elastic finger, and even after the rod is attached, the elastic finger is pushed by the rod and does not bend. Since the rod is in a soldered state, its elastic recovery not only impairs the rotatability of the rod, but also
Since the hole in the substrate is circular and the legs of the holder are cylindrical, there is a problem in that the holder tends to rotate within the hole in the substrate when the rod is rotated.

SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned problems, and its purpose is to provide a holder that allows easy determination of the insertion direction of the rod and has less play when installed.

<Means for solving the problem> The present invention achieves the above objectives, and
The contents will be explained below using examples shown in the drawings.

In the present invention, an engaging portion 7a is provided at one end of the flange portion 7 along the rising portion P' of the substrate P, and the leg portion 9 is provided with an insertion hole that is opened in a direction perpendicular to the engaging portion. It is characterized by providing a slit 13 extending from the lower end of the leg toward the bottom surface of the flange portion, which allows the rod 14 to change direction within the rod 10.

<Operation> First, in order to attach the holder 6 to the board P, align the engaging part 7a of the flange 7 along the rising part P' of the board, align the leg part 9 with the hole 16 of the board, and insert it into the insertion engagement. and fix the holder to the substrate surface.

Next, the rod 14 is attached to the holder fixed to the board.
To attach the rod, align the tip of the rod with the insertion hole 10 and insert it from the head 8 toward the leg. At this time, since one end of the rod is bent, insert the tip into the insertion hole from an oblique direction and look at the engaging part 7a of the flange 7 or the rising part P' of the board P. While inserting the rod in a direction perpendicular to this, the tip of the rod is positioned in the slit 13.

Once the shaft portion (for example, the center shaft portion 15) that becomes the rotational axis midway along the length of the rod has passed through the insertion hole, the rod is raised to make the shaft portion parallel to the insertion hole. At this time, due to the action of the slit, the bent portion of the rod (for example, the second bent portion 14b) changes direction within the insertion hole without any force, the shaft portion fits into the insertion hole, and the rod can pivot around the shaft portion. Then, it is held on the substrate via a holder.

<Example> The present invention will be described below based on the illustrated example.

Reference numeral 6 indicates a holder, and the holder 6 consists of a head 8 having a flange 7 that comes into contact with the surface of the substrate, and legs 9 that extend downward from the bottom of the flange 7 and are inserted into holes in the substrate. , a rod insertion hole 10 is formed in series from the head 8 to the leg 9, and is integrally molded from thermoplastic synthetic resin with appropriate rigidity and flexibility.

The flange 7 has a thick triangular flat plate shape,
An upright engaging portion 7a is formed on one side of the triangle and comes into contact with the rising portion P' of the substrate, and a thick cylindrical head 8 extends from approximately the center of the upper surface.

The inner wall thickness of the side wall of the head 8 gradually decreases upward, and the inner wall surface 8a is tapered upward. In order to prevent the rod from swinging in the left-right direction, a pair of bulges 11, 11 are formed on the inner wall surface 8a, facing each other with a gap equal to the width l of the insertion hole 5 and protruding inward. The bulging portion 11 has a chevron-shaped cross section and has gentle skirt portions 11a, 11a continuous to the inner wall surface 8a.

Further, a cylindrical leg portion 9 extends from approximately the center of the bottom surface of the flange portion 7, and a cylindrical leg portion 9 is deformed into a hole in the substrate and passes through the leg portion 9.
A pair of elastic protrusions 12, 12 are provided which cooperate with the bottom surface of the flange portion 7 and engage with the edge of the hole in a non-returning manner,
A vertically long slit 13 is provided in the side wall 9a of the leg portion 9 upward from the lower end of the side wall 9a, into which one end of the rod fits and allows the rod to change direction within the insertion hole 10.

The elastic protrusion 12 has a downward U-shaped notch in the middle of the length of the side wall 9a of the leg portion 9, and the part surrounded by the notch has a thick chevron-shaped cross section, and protrudes outward from the outer periphery of the side wall 9a. Let it form.

The slit 13 has an inverted U-shape extending vertically from the lower end of the side wall 9a of the leg 9 toward the bottom of the flange 7, and preferably the slit 13 is shaped so that the tip of the rod fits into the slit 13. It is best to set the width to be larger than the diameter of the rod. The slit 13 is provided in a direction perpendicular to the direction in which the bulge 11 of the head 8 faces, and when the tip of the rod is inserted into the slit 13, the bulge 11 of the head 8
This prevents the rod from acting on the rod. In addition, the lower end of the side wall 9a of the leg part 9 is tapered by gradually reducing the thickness of the outer periphery toward the lower end in order to improve the insertability when inserting into the hole of the board. The situation is as follows.

The rod 14 described above has one end bent into an L-shape to form a first bent part 14a, and the tip thereof is bent into an L-shape.
In order to prevent the second bent portion 14b from coming off, the second bent portion 14b is bent into a substantially J-shape. Between the first bent part 14a and the second bent part 14b, a middle shaft part 15 is inserted into the insertion hole 10 of the holder 6 and becomes a rotating shaft.
becomes.

On the other hand, the other end of the rod 14 may have any shape, but for example, when the rod is used as a bonnet hinge, the tip is bent into a hook shape and the hook-shaped portion is inserted into the locking hole on the back of the bonnet. engage,
The rod provides a structure that supports the bonnet from below.

First, a hole 16 is formed in the substrate P, and the hole 16 is large enough to fit the leg part 8 of the holder 6 and passes through the hole 16 from above and below. This hole 16 is opened relatively close to the rising part P' of the substrate P, and when the leg part 8 is inserted into the hole 16, the engaging part 7a of the collar part 7 is inserted into the rising part P'.
Make it contact P'.

Next, to attach the holder 6 to the board P, align the engaging part 7a of the flange 7 with the rising part P' of the board P, align the leg part 9 with the hole 16 of the board P, and insert it from above. do it. When the leg portion 9 is inserted in this manner, its elastic protrusions 12, 12 engage with the edge of the hole 16,
It is pushed by the edge of the hole 16 and bends inward. When the elastic protrusion 12 passes through the lower edge of the hole 16, it expands outward with a snap, catches the lower edge of the hole 16 from below, and cooperates with the bottom surface of the collar 7 to hold the holder 6. It is held on the surface of the substrate P.

In addition, in this attached state, the engaging portion 7a of the holder 6
By contacting the rising portion P' of the substrate P, the lateral mounting play of the holder 6 can be reduced.

Next, the rod 14 is inserted into the insertion hole 10 of the holder 6 from the tip. At this time, the tip of the rod 14 is directed toward the slit 13 of the leg 9.
Insert into the insertion hole 10 diagonally from above.

At that time, when the holder 6 is attached to the substrate P, the legs 9 are located under the substrate P, so the substrate P
Although it is difficult to distinguish the position of the slit 13 from above, since the slit 13 opens in a direction perpendicular to the engaging part 7a,
By looking at the rising portion P', the opening direction of the slit 13 can be easily determined. Therefore, while looking at the engaging portion 7a of the holder 6 or the rising portion P' of the substrate P,
By inserting the tip of the rod 14 in a direction perpendicular to this, the tip can be positioned in the slit 13 within the insertion hole 10.

The tip of the rod 14 is guided by the tapered inner wall surface 8a of the head 8 and enters the insertion hole 10, and the second bent portion 14b passes through the insertion hole 10.
The tip of the rod 14 fits into the slit 13.
Then, the tip of the rod 14 is made to protrude outside the leg portion 9 through the slit 13, and the center shaft portion 15 of the rod 14 is positioned within the insertion hole 10. Next, the rod 14 is raised with respect to the insertion hole 10, the center shaft portion 15 of the rod 14 is made parallel to the insertion hole 10, and the rod 14 is slightly rotated about the center shaft portion 15 as a fulcrum. is engaged with the lower edge 9' of the leg 9 without the slit 13 to complete the installation.

In this state, the second bent part 14b engages with the lower edge 9' of the leg part 9 to prevent the leg from coming off as required, and the first bent part 14a engages with the lower edge 8' of the head part 8. As a result, vertical movement of the center shaft portion 15 of the rod 14 is restricted.

Further, the center shaft portion 15 of the rod 14 engages with the tip of the bulge portion 11 formed on the inner wall surface 8a of the head 8, and the swinging of the center shaft portion 15 in the left-right direction is restricted.

Therefore, the rod 14 is inserted into the insertion hole 10 without play, and the other end of the rod 14 is held on the surface of the substrate P so as to be able to rotate around the insertion hole 10 using the center shaft portion 15 as a fulcrum.

Furthermore, since the engaging portion 7a of the holder 6 comes into contact with the rising portion P' of the substrate P, it is possible to prevent the holder 6 from wobbling or rotating together when the rod 14 turns.

In addition, the rotation range of the rod 14 is the second
A suitable range is such that the bent portion 14b can move along the lower edge 9' of the leg 9 without the slit 13.

FIG. 13 shows a case in which the rod is used as a bonnet hinge, and the holder 6 is supported laterally on the panel edge 17 of the body panel facing the engine room.

According to this, the rod 14 is always fastened to the panel edge 17 in a state of lying sideways along the panel edge 17, and when the bonnet 18 is opened, the rod 14 is fixed to the panel edge 17 in a state of lying sideways. The rod 14 is rotated significantly to make it stand upright, and the hook-shaped hook 19 formed at the tip of the rod 14 is engaged with the locking hole 20 on the back side of the bonnet 18 to support the bonnet 18 from below and lock it in the open state. do. Also, when closing the bonnet 18, the hook part 1 of the rod 14
9 from the locking hole 20, and insert the rod 14 into the center shaft part 1.
5 as a fulcrum, and fasten it to the panel edge 17.

14 and 15 show another embodiment of the present invention, in which a downwardly protruding protrusion 21 is formed on the lower edge 9' of the leg 9.

The protrusion 21 is one step higher than the end surface 22 of the lower end 9' of the leg 9, and both ends are gradually inclined downward to form the end surface 22.
It is consecutive to 2.

Therefore, when the rod 14 is rotated a little after being inserted into the insertion hole 10, the second bent portion 1 of the rod 14
4b rides on the surface of the protrusion 21 and cooperates with the upper edge 8' of the head 8 to restrict vertical movement of the central shaft portion 15 of the rod 14.

According to this embodiment, the central shaft portion 15 of the rod 14
Since the length of the rod can be made sufficiently larger than the length of the insertion hole 10, the ease of inserting the rod can be further improved.

<Effects> As explained above, according to the present invention, since the engaging part is provided at one end of the flange along the rising part of the board, it is possible to reduce the looseness when the holder is attached to the board. This prevents the holder from wobbling or rotating together when the rod turns.

In addition, the leg portion is provided with a slit extending from the lower end of the leg toward the bottom surface of the flange portion to allow the rod to change direction within the insertion hole, and this slit is opened in a direction perpendicular to the engaging portion. It is easy to position the tip of the rod in the slit within the insertion hole of the holder, and the direction of the rod can be changed relatively easily. Moreover, even if the overall length of the insertion hole is set long and the length of the central shaft portion, which is the rotation axis of the rod inserted into the insertion hole, is also increased, the insertability of the rod will not be impaired. By doing so, the lateral deflection of the rod relative to the insertion hole can be reduced. Similarly, each bent part of the rod can be bent to match the upper edge of the head and the lower edge of the legs of the holder without impairing the insertability of the rod, so there is no play in the axial direction of the rod with respect to the insertion hole. It is also possible to reduce the amount of stickiness.
