Description

[Detailed description of the invention] This invention is made of plastic that connects the plates face-to-face and unites them into one piece, while making it possible to release the connection between the plates with a simple operation if necessary. This invention relates to a connecting tool for connecting plates.

To explain in more detail, the connector of the present invention includes a main body of the connector, each of which has engaging legs on both sides of a flange-shaped base plate, and is fitted into one of the engaging legs of this main body.
It is composed of a release member that releases the engagement by forcibly reducing the diameter of an elastic locking claw derived from the locking leg, and when connecting the plates, the locking leg is provided in the main body through a hole drilled in each of the plates. to engage and establish the connection, and when releasing this connection, operate the release member to reduce the diameter of the elastic locking claw of the engaged leg, and engage with the through hole. To provide a plate connector which can release the connected state by releasing the plate.

Conventionally, connectors made of plastic have been used as a means of connecting plates together, but conventional connectors of this type simply have two engaging legs arranged backwards between a base plate or a base. , it is possible to connect the plates by pushing this engagement leg into a hole drilled in the plate, but there is no means to release this engagement, so when the plates are uncoupled. has become extremely troublesome.

In particular, if the back sides of the connected plates, that is, the side where the engaging legs are locked, are exposed and the hand or tool can be inserted freely, the engaging claws of the engaging legs can be directly operated to engage. It is possible to remove the plate and release the connection state, but if the locking claw engaged with the through hole of the plate cannot be directly operated, or if the plates are connected with multiple connectors and the If all the connections cannot be removed at the same time, it is not appropriate to use the above-mentioned conventional connections as connections between plates that are scheduled to be disassembled.

The present invention was devised in view of these circumstances, and while it is possible to connect plates by pushing the engagement leg into a through hole provided in the plate, it is also possible to easily operate the engagement leg inserted into the through hole. A plate connection that can be pulled out and released from the engagement state, and also allows the plates to be released from each other even when they are held in this release state and fastened together using a plurality of connectors as described above. The aim is to provide the tools.

Hereinafter, a description will be given of an embodiment illustrating this invention.
is a main body of a connector having a second engaging leg 4 on the other side, and 5 is a release member fitted into the second engaging leg of the main body.

The first engaging leg 3 of the main body 1 is formed into a rectangular cylinder shape, and the two opposing walls have a tongue-shaped notch formed by cutting the wall surface into a substantially U-shape. Locking claws 6, 6 are provided.

The locking pawl 6 has a connecting portion 7 on the distal end side of the leg, and the free end can be bent into the hollow portion 8 of the leg using this connecting portion as a base, and the outer surface of the locking pawl is attached to the wall. A claw 6' is provided on a chevron-shaped protuberance that protrudes outward from the surface of the protrusion.

The second engagement leg 4, which is provided opposite to the first engagement leg 3, has a plate-shaped support 9 that stands up from the center of the surface of the board 2, and a plate-shaped support 9 that extends backward from both sides of the tip of this support. It consists of elastic locking pawls 10 extending in the opposite direction, and each elastic locking pawl 10 is folded back from the tip of the support column toward the substrate 2, so that the entire cross section including the support column 9 has a substantially anchor shape. It is shaped like this. The elastic locking pawl 10 is formed into a rod shape, and its outer surface is raised in a chevron shape similar to the locking pawl 6 of the first locking leg 3, and a nail is formed on the outside surface near the tip of the locking pawl. 10' is provided.

On the other hand, the release member 5 is formed into a cap shape and has a flange 11 all around the hem, and windows 12, 12 are provided on the circumferential surface of the cylindrical body.

This release member 5 is formed in a size that can receive the entire second engagement leg 4 consisting of a support 9 and an elastic locking claw 10, and a window 1 formed on the circumferential surface of its body.
2 is provided corresponding to the elastic locking pawl 10 described above.
This window is formed vertically with respect to the circumferential surface of the body so that the elastic locking claw 10 projects outward through this window, and one side 13 of the window extends from the top side of the release member to the hem side. The window is slanted toward the window so that the overall shape of the window is approximately a right triangle. Further, in this embodiment, a projection 14 is provided at the top corner of the window 12, and this projection 14 is connected to an elastic locking pawl 10 extending from the support 9 of the engaging leg 4, as will be described later. This is to engage with a recess 15 formed on the outer surface of the base to increase the locking force while ensuring the flexibility of the elastic locking pawl 10.

In addition, 16 in the figure indicates when rotating the release member,
This is a groove provided at the top to hang a tool 17 such as a screwdriver.

The connector main body 1 and the release member 5 configured as described above are each separately integrally molded from a plastic material having appropriate rigidity and elasticity, such as nylon resin, and after molding, the second engagement leg 4 of the main body 1 is The release member 5 is fitted so as to cover it, and after the two elastic locking claws 10 of the entry leg 4 are once reduced in diameter, they are brought back to their original positions facing the respective windows 12 opened on the circumferential surface of the trunk, and the openings are inserted through the windows. By causing the pawl 10' to protrude outward from the circumferential surface of the release member, it is assembled into a single connector.

FIGS. 8 and 9 show the completed state of the inventive connector, and FIG. 10 shows the state in which two plates A and B are connected using the inventive connector.

The two plates A and B to be connected are not particularly limited, but here, one plate A is the metal plate on the bottom surface of the top of a steel office desk, and the other plate B is the metal plate on the top surface of the desk body. A case is shown in which the coupling device of the present invention is used as a metal plate piece for fixing the top plate to be provided.

Plate A has a square hole a that matches the cross-sectional shape of the first engaging leg 3 of the coupling device of the present invention, and plate B has the cross-sectional shape of the release member 5 fitted into the second engaging leg 4. A circular hole b adapted to the plate A is opened in advance, and the plates are connected to each other by inserting the first engagement leg 3 into the hole a of the plate A, and inserting the second engagement leg 4 into the hole a of the other plate. This is done by inserting into hole b provided in plate B.

Note that the engagement of both the engagement legs 3 and 4 is done by simply pushing them in, but if multiple connectors are used to fix the top plate, multiple holes a are provided in the metal plate on the bottom of the top plate. Insert the first engaging leg of each connector to fix it in advance, and then push it downward into hole b, which is prepared in the metal plate piece of the desk body to correspond to hole a above. By exposing each second engagement leg 4 and pressing the top surface of the top plate, connection and fixation at multiple points can be performed simultaneously.

In this way, the connecting device of the present invention is operated by pushing both the engaging legs 3 and 4 into the holes in the plate, and the locking claws 6 and elastic locking claws 10 of each of the engaging legs are inserted into the holes. When passing through the hole, the diameter is once reduced and then expanded and restored on the opposite side, and the claws 6' and 10' are hooked to the edge of the hole to connect and fix the plates together. By rotating 5, the second engaging leg 4 can be released from the locked state and the connection can be released.

That is, when it is necessary to release the plates after they have been connected, a tool 17 such as a screwdriver is hooked into the groove 16 of the release member 5 protruding from one side of the plate B, and the tool 17 is rotated in the direction of the arrow as shown in FIG. , the inclined side 13 of the window 12 rests on the outer surface of the elastic locking claw 10 of the second locking leg and uses the slope as a guide to pull this elastic locking claw into the inside of the release member. The second engagement leg can be easily pulled out from the engagement hole.

As described above, the connecting device of the present invention can easily connect plates by pushing the first and second engagement legs extending from both sides of the main body plate into holes drilled in each plate. On the other hand, if necessary, the elastic locking claw 10 can be disengaged and pulled out by rotating the release member 5 fitted to the second locking leg 4. The connection state can be easily released.

Then, this coupling device provides a locking mechanism again by further rotating the release member 5 or rotating it in the opposite direction to return the elastic locking pawl 10 that has been pulled inside to the position of the window 12. Therefore, the connection can be made again, and the elastic locking pawl 10 can be pulled into the release member as described above and locked in a state where it cannot be locked. When a board is fixed with a plurality of connectors, the entire top board can be peeled off at the same time by one person by disabling each of the locking legs one after another. Therefore, it is advantageous not only in connection work but also in release work.
