[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a top plate mounting apparatus for a box having a drawer such as a cabinet or a side table.

[0002]

2. Description of the Related Art As described in Japanese Utility Model Application Laid-Open No. 2-121828, for example, a bolt is attached from the inside of a box body to a well-known side box or the like in a box body such as a side desk. A method of inserting and screwing into the top plate, thereby fixing the top plate to the side table main body, has been adopted.

[0003]

However, in such a conventional mounting operation, it is necessary to first remove a drawer from the box body in addition to the bolt tightening step. Therefore, it is not preferable from the viewpoint of work efficiency to tighten the bolt upward, and in some cases, a step of turning the box upside down is also required.

The present invention has been made in view of the above-mentioned problems, and has made it possible to attach the top plate to the box body very simply and securely by the minimum necessary work steps. It is an object to provide a top plate mounting device.

[0005]

In order to achieve the above-mentioned object, a top plate mounting device for a box body according to the present invention has an opening at an upper surface, and a box having a horizontal bar provided at the front and rear of the opening. A body plate and a top plate formed by vertically suspending a rearward engaging piece at a rear portion of the lower surface, a locking claw at the front portion, and a guide pin near the locking claw. The engaging piece of the top plate is engaged with the front piece of the rear horizontal rail of the box body, and the locking claw is elastically engaged with the hanging piece of the front horizontal rail of the box body. Further, the top plate is positioned and attached to the box body by engaging the guide pin with a guide hole formed in the front horizontal rail of the box body. And

[0006]

When mounting the top plate, first, the engaging piece of the top plate is engaged with the rear cross rail of the box body, and then the top plate is pivoted downward with the engaging portion as a fulcrum. Then, the top plate is pushed downward from above so that the locking claws are elastically engaged with the front horizontal rails of the box body. Thereby, the top plate is fixedly attached to the box body.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show the overall configuration of a top plate (1) integrally formed of a synthetic resin.

A plurality of rearward engaging pieces (2) are provided at the rear of the lower surface of the top plate (8), and frontward engaging claws (3) are also provided at the front left and right.
In the same manner, a regulating piece (4) is provided at the center on both the left and right sides, and a vertical guide pin (6) and an elastic locking piece (5) are integrally provided behind each locking claw (3). It is provided in. Immediately after the locking hole (3), a recess serving as a handle (7) is provided on the upper surface of the top plate (1).

As shown schematically in FIG. 4, the top plate (1) is a box body having a drawer such as a cabinet or a side desk.
It is attached to the upper surface of (8). The box body (8) has an open upper surface, and has horizontal rails (9) and (10) installed at the front and rear portions thereof.

As shown in FIGS. 4 and 5, the front cross bar 9 has a substantially U-shaped cross section as viewed from the side. A horizontal piece (12) to which the locking claw (3) can be locked is continuously provided rearward, and a top end of the rear piece (13) has a guide hole (14) into which a guide pin (6) can enter. A rearward horizontal piece (15) is continuously provided, and a hanging piece (16) to which the elastic locking piece (5) can be locked is continuously provided at a rear end of the rearward horizontal piece (15).

The rear crosspiece (10) has an inverted L-shaped cross section when viewed from the side, and its front piece (17) has a notch (18) into which the engagement piece (2) can be fitted and engaged from the front. ) Is provided.

An inward piece that guides the top plate (20) by sliding the regulating piece (4) on the upper end of the side plate (19) of the box body (8).
(20) is provided.

When attaching the top plate (1) to the box body (8), first, the engaging piece (2) of the top plate (1) is attached to the front of the rear crossbar (10) of the box body (8). The top plate (1) is rotated downward with the contact portion as a fulcrum. In this turning process, the engagement piece (2) slides along the front piece (17) and then engages with the notch (18). At this time, the left and right regulating pieces (4) of the top plate (1) are the inward pieces (20) of the side plates (19) of the box body (8).
, The movement in the left-right direction is suppressed.

In the final stage of the turning process, the locking pawl (3) resiliently engages with the lower part of the rear edge of the horizontal piece (12) of the front cross bar (9). At this stage, the elastic locking pieces (5) and the guide pins (6) are also attached to the hanging pieces (16) (1)
4) and the guide hole (14) to additionally regulate the mounting position of the top plate (1) with respect to the box body (8), and thus the top plate (1) is attached to the box body. Completely attached to (8).

In a state where the top plate (1) is attached to the box body (8), a handle provided as a concave portion on the top plate (1) is provided.
Conveniently, the front side on the back side of (7) is in contact with the rear side of the front crossbar (9). This is because when a pulling force is applied to the handle (7) to pull the box body (8) forward, this force is
Due to the slight elastic deformation of the top plate (1),
This is because the signal can be transmitted directly to the box body (8) via (9). Therefore, even if a relatively large pulling force acts, the handle portion (7) and the top plate (1) do not break or come off unexpectedly.

The top plate (1) is detached from the main body (8) by using a suitable tool such as a screwdriver, for example, by using a locking claw.
(3) and the elastic locking piece (5) are forcibly bent backward,
After each disengagement, this is easily done by turning the top 1 in the opposite direction, ie upward. In this case, the upward engaging surface of the engaging piece (2) is notched.
After slightly sliding along the upper edge of (12), by riding on the surface of the front piece (11) of the rear crosspiece (10), the engagement between the engagement piece (2) and the notch (12) It is released.

[0017]

[Effects of the Invention] (a) When attaching the top plate to the box body, it is not necessary to pull out the drawer or to turn the box body upside down. Can be attached to the body.

(B) A rearward engaging piece provided at the rear of the lower surface of the top plate and a locking claw also provided at the frontal part are provided on the rear horizontal rail and the front horizontal rail at the upper opening of the box body. By engaging each of them and inserting a guide pin vertically provided from the vicinity of the locking claw into a guide hole formed in the front horizontal rail of the box body, the position of the top plate is correctly maintained, and The front, rear, left and right positions of the plate and the box body are easily and reliably adjusted.

(C) Even if external force is applied to the top plate and the box body, the position of the top plate does not shift with respect to the box body because the guide pins are engaged with the guide holes.

(D) In the invention of claim 2, regulating pieces are vertically provided on the left and right sides of the lower surface of the top plate, and the regulating pieces contact the inward pieces on both sides of the upper opening of the box body. Position of the top plate and the box body is more reliably adjusted, and even if a large external force is applied to the top plate and the box body, the position of the top plate is shifted to the side. Never.

(E) As in the invention of claim 3, the notch provided in the rear horizontal rail of the box body is adapted to be engaged with the engagement piece vertically provided from the rear of the lower surface of the top plate. In this way, the left and right position adjustment of the top plate and the box body can be performed more reliably at the front and the rear, and even if a lateral external force is applied to the top plate and the box body, the position of the top plate will not shift. Absent.
