Description

[Detailed description of the invention] The present invention consists of assembling the top plate stopper of the assembly desk, that is, the sleeves, leg plates, rear curtain plate, etc., to form the desk body.
The present invention relates to a fastener that allows the top plate to be easily and firmly attached to the desk body with one touch.

As a stopper for simply connecting members, a stopper locking piece having a pawl portion having an inclined surface has been known, for example, as shown in Utility Model Publication No. 48-2519, Utility Model Publication No. 42-19713, etc. Since these fasteners are made of plastic and utilize only the elasticity of the material to latch the pawl to the latch opening of the mounting part of the plate, etc., the relationship between the pawl and the latch opening is There remains the problem that the engagement force is weak, and the deterioration of the plastic causes the locking pieces to lose their elasticity, making the engagement of the pawls uncertain. Because it is used alone without using a
In addition to the locking piece, it is necessary to provide a guide piece for fixing the stopper, which complicates the structure and manufacture of the stopper.In particular, since it is made of plastic, there remains the drawback that it is difficult to mold it in one piece. Ta. Furthermore, in order to make the installation of this fastener simple and firm, the structure of the fastener itself and the latch opening that engages with the claw are important elements, but the above-mentioned prior art latch The holes were simply drilled, making attachment of fasteners difficult and unreliable. Therefore, with such conventional fasteners and their mounting structure, like the top plate of an assembly desk, by pressing the top plate with the fasteners fixed to the bottom surface from above against the desk body, the sleeves and leg plates can be fixed. Installation situations where it is not possible to perform the installation while directly observing the fit between the stopper and the latch hole, such as when attaching the stopper to a latch hole formed on the top surface of a ceiling plate. At the bottom, it is extremely difficult to fit the stopper and the latching hole, and in the case of a desk top, it is often necessary to hold the top when moving the desk, so it must be installed securely. Such a firm connection could not be expected with a plastic fastener that only utilizes the elasticity of the material.

To explain the fastener of the present invention with reference to the attached drawings below, the locking piece 1 is placed inside a guide body 6 made of a metal plate that is approximately the same length as the locking piece 1 or shorter than that.
The locking piece 1 is provided with a claw formed at its lower end projecting outward, and is pivotally mounted within the guide body so as to be rotatable within a certain range, and the locking piece 1 is provided with an elastic body provided within the guide body. The claw portion 2 is elastically biased in the direction of engagement with the locking hole of the mounting portion, and the locking piece 1 is made of metal or synthetic resin, and has a thick upper end and a lower end. A slope 3 facing inwards and downwards is formed, a pawl portion 2 having a substantially horizontal detent surface 4 is provided continuously on the upper edge of the slope, and a through hole 5 is formed through the upper end in the lateral direction. The guide body 6 that stores and holds this locking piece is attached to the lower surface of the desk top plate by appropriate means, and its structure is as shown in FIG. In addition to being curved, the lower end edges of both side walls 7 form an inwardly downward inclined guide edge 9, a bearing hole 10 is formed at the upper end, and stop pieces 11 are formed by bending the open 8 side edges of both side walls 7. The locking piece 1 is fitted into the hollow portion surrounded by the rear wall 12 of the guide body 6 and the side walls 7, 7 and the locking pieces 11, 11, and the locking piece 1 of the bearing hole 10, 10 of the guide body 6 is fitted. The rear wall 1 of the guide body is inserted through the through hole 5 through the pivot 13.
2 and a stopper piece 11, and an elastic body 14 provided between the locking piece 1 and the guide body 6 applies elastic pressure to the locking piece 1 so that its claw portion 2 faces outward. It is strong. As an example of this elastic body 14, a spring as shown in the drawing is fitted onto the pivot 13, and the tip of the spring is used to spring the rear surface of the locking piece 1 and the inner surface of the rear wall of the guide body 6, so that the locking piece 1 is always kept on the locking piece. It is maintained in a pressed state at 11.

On the other hand, the latching opening 16 that engages with the stopper A as described above is formed on the upper end surface of the mounting base 15 such as the sleeve part of the desk body or the leg plate, and as shown in FIG. A latch opening 16 is formed by punching on the upper surface of the base 15, and at the same time as the punching, a plate material, such as a steel plate, of the mounting base 15 is bent to form tapered pieces 17, 17.
The tapered piece 1 is constructed by further bending the tip 18. When a thick plate material that is difficult to bend is used, the latching opening 16 is simply punched out and the tapered piece 1 is formed.
7 and 17 may be sufficient.

The top plate stopper of the present invention is constructed as described above, and the stopper A is fixed to the bottom surface of the top plate B of the assembly desk by an appropriate means and inserted from above into the latching opening 16 provided on the attachment base 15. The slope 3 of the locking piece 1 and the inclined guide edge 9 of the guide body 6 slide and guide on the tapered piece 17, and the locking piece 1 slides downward and at the same time resists the elasticity of the elastic body 14. When the locking piece 1 is pushed into the guide body 6 and then passes the lower end of the locking port 16, the detent surface 4 of the claw portion 2 of the locking piece 1 is pushed into the locking port 1.
The elastic body 14 is hooked to the lower end bend 18 of the
This elasticity also pushes the inclined guide edge 9 of the guide body 6 against the tapered piece 17, thereby attaching the stopper A to the mounting base 15, that is, attaching the top plate.

Therefore, according to the top plate stopper of the present invention, even if the stopper is fixed to the bottom surface of the top plate and the latching opening between the stopper and the attachment base is not visible from above the top plate, the stopper can be fixed to the bottom surface of the top plate. At the lower end, a slope 3 is formed on the locking piece 1, and the lower edge of the guide body 6 is formed as an inclined guide edge 9. Since the stopper A is inserted into the locking port 16 along the same direction, it is extremely easy to insert and attach the stopper A to the locking port 16, and the locking piece 1 can be rotated within a certain range within the box-shaped guide body 6. It is movably pivoted and held, and the elastic body 14 urges the claw portion 2 in the direction of engaging the latch port 16, so that the engagement between the claw portion 2 and the latch port 16 is ensured. In addition, this elasticity causes the lower edge of the guide body 6 to be pressed by the tapered guide edge 9 against the tapered piece 17, so that the fastener can be firmly attached.
