Description

[Detailed description of the invention] [Industrial field of application] The present invention is designed to allow the lid of an accessory case to be detachably attached to the opening edge of an accessory case provided in the body panel of an automobile, for example, with a sense of moderation. This invention relates to a plastic plate connector made of plastic.

[Prior Art] Conventionally, there have been plate connectors for detachably attaching two plates in contact with each other as shown in FIGS. 8 and 9.

This plate connector has a head 51 having a plate part 52 hanging down from the lower surface of the plate part 52, and a lid plate 5 around it.
A locking leg 55 is provided with a non-return means 54 that deforms when pushed into the mounting hole 53a at 3, passes through the mounting hole 53a, and holds the cover plate 53 between it and the lower surface of the head 51. Thin hinge 56 at the lower end of the locking leg 55
It extends diagonally upward along the open side of the locking leg 55, has an upper end protruding upward from one side of the plate part 52, and is fixed to the outer surface in contact with the lower surface of the cover plate 53. An auxiliary piece 59 having a claw 58 that can lock the hole in the plate 57 from behind, and an auxiliary piece 59 provided in the area of the locking leg 55 facing the locking leg 55.
It has a tongue-like spring piece 60 that protrudes into the hollow part of.

[Problem to be solved by the invention] However, the above plate connector has a tongue-like spring piece 60.
Since the lid is made of plastic, the spring piece 60 deforms after long-term use, resulting in a decrease in elasticity, which causes the lid to move slowly when closed, resulting in a lack of sense of moderation.

The present invention solves the above problems by increasing the movement of the operation plate when closing the lid, and increasing the elastic force so that the lid is securely and securely locked to the edge of the opening. The purpose is to provide coupling devices.

[Means for Solving the Problems] In order to achieve the above object, the present invention configures a plate connector as follows. That is, a leg 2 is provided protruding from approximately the center of one surface of a U-shaped support plate 1 having plate-shaped wing portions 1a, 1a at both ends, and a leg 2 is provided on the tip side of the leg 2. An elastically deformable locking piece 3 that protrudes from the side of the support plate 1 is provided at the tip of the leg 2, and extends from the tip through a thin section and is folded back at the thin section. an arm 5 provided so as to protrude from between the wing portions 1a, 1a on the support plate 1; and an arm 5 provided at the tip of the arm 5 protruding from between the wing portions 1a, 1a 1a, 1a are provided with an operation plate 6 whose both sides are engaged, and a conical coil spring 8 is provided between the folded arm 5 and the leg 2, and the arm A locking piece 7 is provided on the outer surface of the leg 2 which holds the conical coil spring 8 between the legs 5 and 5.

[Operation] The plate fastener having the above-mentioned configuration has the legs 2 from the free end side,
For example, when the locking piece 3 is inserted into the mounting hole of the lid A of a small storage compartment of an automobile, the locking piece 3 is elastically deformed and pushed in.
The step portion 3a is attached to the lid A by pressing the lid A against the support plate 1 with the edge of the mounting hole.

Next, when the leg 2 is inserted into the hole at the opening edge of the pocket provided in the panel B, the arm 5 is pushed up by the hole edge on the sloped surface of the part that gradually becomes thicker from the tip, so that the locking claw 7 passes through the hole. However, since the arm 5 is urged by the conical coil spring 8, the locking pawl 7 locks on the inner edge of the hole after passing through the hole edge.
Attach lid A to panel B.

Since the locking pawl 7 is elasticized by the conical coil spring 8 in this way, the elastic force is strong, and the conical spring 8 can be compressed to the height of the diameter of the coil material when compressed. Since the movement of the locking pawl 7, that is, the movement of the arm 5, can be increased, the lid A
When closed, it moves quickly and is large, so there is a sense of moderation.

[Example] Hereinafter, an example of the plate connector according to the present invention will be described with reference to the drawings.

This plate connector is made entirely of plastic except for the conical coil spring 8, and 1 is a U-shaped support plate having plate-shaped wing parts 1a, 1a on both sides. Parallel to the support plate 1 which is connected to the rising walls 1a', 1a' and 1b' provided on the outer edges of the parts 1a and 1a and the outer edge of the plate part 1b between them, and is provided so as to cover the support plate 1. A case 9 in which an operation plate 6, which will be described later, is housed is formed by a decorative plate 1'. The decorative board 1' has a wing part and a plate part wider than the support plate 1, and the wing part is longer than the wing part 1a of the support plate 1.
The U-shaped inner edge of the support plate 1 is not visible from the decorative plate 1'.

The support plate 1 has a plate portion 1b between both wing portions 1a and 1a.

In addition, the side wall 2b has a rising width larger on the inner side than on the outer side from the center of the thickness width, and the rising width is slightly larger than the dimension of the mounting hole of lid A, and the rising dimension on the outer surface side is the dimension of the mounting hole. It is made slightly smaller, and when the leg 2 is pushed into the mounting hole, the edge of the side wall 2b bites into the mounting hole, minimizing play.

Each wall surface of the locking leg 2 at its free end is inclined in a tapered shape, and furthermore, protrusions 2c, 2c, which are formed in a tapered shape and protrude from the outside of the tip of both side walls 2b, are provided, so that when the lid A is closed, The locking leg 2 is designed to be easily inserted into the hole on the panel B side.

Further, an elastically deformable locking piece 3 provided away from the side wall 2b toward the support plate 1 from the protrusion 2c at the free end of the side wall 2b is formed to have a width narrower than the rising width of the side wall 2b. has been done. This locking piece 3 has a step 3a at its tip for locking to the mounting hole edge of the lid A, and this step 3a has a protrusion 3a' facing the support plate 1 and a protrusion from the outside of the locking piece 3. It has an inclined surface 3a'' that tapers toward the base of the lid A, and when the leg 2 is inserted into the mounting hole of the lid A, the locking piece 3 is once elastically deformed toward the side wall 2b and passes through the hole. After passing through the hole, the restoring elastic force of the locking piece 3 causes it to be locked to the hole edge by the protrusion 3a' of the step part 3a, and pressed against the surface of the support plate 1 by the inclined surface 3a''. It is designed to be fixed to lid A.

9a is the lid A during the engagement/disengagement operation of the plate connector.
In order to reduce tilting relative to the mounting surface of the case 9, a protrusion is provided on the outer surface of the rising wall 1b' of the case 9, and has a surface in contact with the lid A that is flush with the protruding surface of the leg 2 of the support plate 1. These are projecting portions near both sides of the rising wall 1b'.

Furthermore, a concave portion 2 is provided on the inner surface of the wall 2a of the leg 2.
A locking protrusion 2d is provided at a portion of the side wall 2b close to the inner wall 2a, and the conical coil spring 8 is inserted with its large diameter side into the recessed portion 2a'.
It is secured and installed by.

The hole in the wall 2a is a hole for removing the protrusion 2d from the mold.

The leg 2 is provided with a thin hinge portion 4 at the free end of the wall 2a, and an arm 5 extends from the hinge portion 4 to the inner surface of the support plate 1 in a folded manner between the wing portions 1a, 1a of the support plate 1. is provided at the tip of the arm 5, and an operation plate 6 having a length close to the distance between the upright walls 1a', 1a' of the case 9 is arranged so that the length direction thereof is parallel to the plate part 1b of the support plate 1, and the operation plate 6 is parallel to the plate part 1b of the support plate 1. Installed orthogonally.

The arm 5 is formed to gradually become thicker from the hinge portion 4 side to the support plate 1 side, and has a portion where the surface opposite to the leg 2 is an inclined surface facing toward the distal end of the arm 5, and this portion. It consists of a part that is slightly bent from the end of the leg to the leg 2 side. A locking pawl 7 facing the support plate 1 is formed on the opposite side of the contact leg 2 of both parts, and the arm 5 has a width that allows it to swing into the U-shaped groove of the leg 2. The small-diameter side of the conical coil spring 8 is in contact with the surface of the leg 2 facing the wall 2a, and is elastically biased by the coil spring 8.

Therefore, the arm 5 is attached to both wing portions 1a, 1 of the support plate 1.
The position where both ends of the operation plate 6 are in contact with and suspended between
It is swingable between positions where it abuts against the rising wall 1b' of the support plate 1, and springs toward the position where it abuts on both wing pieces 1a, 1a of the support plate 1.

In the plate connector constructed in this way, when the leg 2 is inserted into the mounting hole of the lid A and the support plate 1 is inserted to the position where it touches the surface of the lid A, the stepped portion 3 at the tip of the locking piece 3 is inserted.

When the locking pawl 7 passes over the edge of the hole, the arm 5, which is being urged by the conical coil spring 8, returns to its original state at once, and the locking pawl 7 is locked to the inner surface of the hole in panel B, and the lid is closed. Panel A and panel B are joined together with their surfaces overlapping each other.

Also, the lower end of the operation plate 6 is connected to a conical spring 8.
If you pull the push-up lid A against the elastic force of
The locking claw 7 of the arm 5 is no longer locked to the edge of the hole in the panel B, so the lid A is disconnected from the panel B.

[Effects] As described above, the plate connector according to the present invention is constructed as described above, so that by pushing the legs into the mounting holes of one plate, the locking pieces and the support plate provided on both sides of the leg can be inserted. and is attached to this board by anchoring the board,
By pushing the leg into the hole drilled in the other plate, the locking pawl is pushed into the leg against the elastic force of the spring, and at the same time as it passes through the edge of the hole, it returns to its original position due to the elastic force of the spring. The plate jumps out to the state of , and locks onto the edge of the hole, thereby joining both plates.

Since the spring is a metal spring, the elastic force does not decrease even after long-term use, unlike conventional models that utilize the elastic deformation of plastic, and the locking pawl has an excellent sense of moderation when operating, so it can be used for a long time. A sense of moderation is maintained throughout. Moreover, a desired elastic force can be obtained by changing the spring.

In addition, since a conical coil spring is used, the height when compressed can be compressed to the diameter of the coil wire material, and the movement range of the arm, that is, the operating range of the locking pawl is wide, and the locking and disengaging of the pawl from the edge of the hole is reliable. .
