Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auxiliary top plate device which can be mounted on a desk to increase a space for a mouse or the like.

[0002]

2. Description of the Related Art A table for a personal computer in which an auxiliary top plate for a mouse can freely move forward and backward in front of a main top plate is disclosed and known in, for example, Japanese Utility Model Publication No. 5-27853.

[0003]

In this example, the auxiliary table is suspended just below the desk table so that it can slide back and forth freely, or the auxiliary table is raised and lowered by a vertical rotating shaft. But in these cases,
It is not easy to use because there is a step between the main table and the auxiliary table.

Further, since the auxiliary top plate is mounted on the lower surface of the main top plate, it must have a strong structure in consideration of the cantilever load, and must be flush with the main top plate when the auxiliary top plate is used. In order to do so, the auxiliary top plate device must have a complicated structure which has both a pull-out means and an elevating means, and has stopper means at each position.

[0005] The present invention has been made in view of the above-mentioned problems of the conventional technology, and can be easily attached to and detached from a desk by using a drawer of the desk.
It is an object to provide an auxiliary top plate whose upper surface can be made flush with the top plate.

[0006]

According to the present invention, the above-mentioned problem is solved as follows. (1) A pair of left and right stoppers is provided on the lower surface of the auxiliary top plate whose left and right width dimension (A) is larger than the dimension (D) between the left and right side plates in the drawer of the desk. (E) is projected downward so as to be substantially equal to the distance (D) between the side plates, and the stopper is brought into contact with the inner side surfaces of both side plates of the drawer pulled out from the desk, so that the auxiliary top plate is By placing it on the upper surface of the drawer, the upper surface of the auxiliary top plate is substantially flush with the upper surface of the desk top plate.

(2) In the above item (1), the left and right widths (A) of the auxiliary table are smaller than the depth (C) of the drawer, and the depth (B) of the auxiliary table is It shall be smaller than the width dimension (D) on the left and right sides of the drawer.

[0008]

An embodiment of the present invention will be described below with reference to the accompanying drawings. The desk (1) has a sleeve box (4) in which a plurality of drawers (2) and (3) are arranged vertically.
And a top plate (5) placed on the upper surface of the sleeve box (4).

The drawer (2) connects the front end and the rear end of the left and right side plates (6) and (6) with the front plate (7) and the rear plate (8), respectively, and connects the lower surface to the bottom plate (9). ) And sleeve box (4)
Can move in the front-rear direction along a front-rear rail (not shown) provided in the inside.

In FIG. 1, an auxiliary top plate device (10) smaller than the internal size of the drawer (2) is housed in the uppermost drawer (2) which is pulled out halfway.

The auxiliary top plate device (10) has a rectangular shape in a plan view in which the width (A) is longer than the depth (B), and has the width (A).
Is smaller than the depth dimension (C) of the drawer (2), and the depth dimension (B) is the distance between the inner surfaces between the left and right side plates of the drawer (2).
(D) Two stoppers (12) and (12) facing the depth direction of the auxiliary top plate (11) are attached to the lower surface of the auxiliary top plate (11) smaller than (D).

The two stoppers (12) and (12) are symmetrical to each other, have an inverted L-shape in cross section, and have horizontal contact portions (13) and (13) and contact portions (13) and (13). ) Are provided with stopper portions (14) (14) hanging down from the inner end portion.

Distance between outer surfaces of both stopper portions (14) (14)
(E) is the distance between the inner surfaces of both side plates (6) and (6) of the drawer (2).
(D), and the distance (F) from the lower surface of the contact portion (13) to the upper surface of the auxiliary top plate (11) is from the upper surface of the side plate (6) to the upper surface of the top plate (5). It is almost equal to the distance (G).

Next, a procedure for attaching the auxiliary top plate device (10) taken out from the drawer (2) as shown in FIG. 2 to the drawer (2) will be described.

First, the drawer (2) is drawn from the sleeve box (4) slightly longer than the depth (B) of the auxiliary top plate (11),
After the direction of the auxiliary top plate device (10) is shifted by 90 ° from the state of FIG. 1, the stoppers (12) and (12) are fitted into the drawer (2), and the stopper portions (14) (14) Of the side plates (6) and (6) and the contact portions (13) and (13) with the side plates.
(6) Place on the upper surface of (6) (see FIGS. 3 and 4).

After that, the drawer (2) is pushed back to the sleeve box (4) side to bring the inner surface of the front plate (7) into contact with the front end of the stopper (12), and the auxiliary top plate (11) When the rear end surface is brought into contact with the front end surface of the top plate (5), the top surfaces of the top plate (5) and the auxiliary top plate (11) are flush (see FIG. 5).

[0017] An auxiliary top plate device attached to the drawer (2)
In (10), since the stopper portion (14) abuts against the inner side surface of the side plate (6), there is no deviation in the left-right direction.
The front end of 2) and the rear end of the auxiliary top plate (11)
Since the inner surface of (7) is in contact with the front end surface of the top plate (5), there is no deviation in the front-rear direction.

According to this embodiment, the space used by the mouse can be easily added to the top plate (5) of the desk (1), and the upper surface of the auxiliary top plate device (10) can be attached to the desk (1). 1) Top plate
Since it can be flush with the upper surface of (5), the usability of a mouse or the like is good. Moreover, when the mouse or the like is not used, the auxiliary top plate device (10) can be stored inside the drawer (2), which is very convenient.

[0019]

According to the present invention, the following effects can be obtained. (a) The use space of the mouse can be easily added to the desk top, and the upper surface of the auxiliary top device can be flush with the upper surface of the desk top.
(Claim 1).

(B) According to the second aspect of the invention, when the mouse or the like is not used, the auxiliary top plate device can be stored inside the drawer, which is very convenient.
