Description

[Detailed description of the invention] This invention relates to a desk, and its purpose is to divide the top plate into two parts, front and back, so that the rear top plate can be raised and lowered freely, and the front top plate can be slid back and forth. It can be used not only for general office purposes but also for office automation.

Conventional office desks have a single top plate and are suitable for general office work, but as office automation (OA) so-called personal computers are used for general office purposes, traditional office desks are equipped with monitors and TVs. When used as an OA table with a keyboard mounted on it, the keyboard is placed in front of the monitor TV, but the keyboard covers the bottom of the monitor TV, and the keyboard is located a little high, making it difficult to operate. There is. Therefore, the top of the desk was divided into two parts, front and back, to be used as an OA table.The rear top was placed at an upper position suitable for placing a monitor table, and the front top was placed at a lower position for easy operation of the keyboard. Although it is fixed in a stair-like manner, it is difficult to use this OA table for general office purposes.

In view of this, the present invention divides the top plate into two, front and back.
By providing one side that can be raised and lowered, and the other side that can be slid horizontally in the front and back directions, it can be used as both a general office table and an OA table.Furthermore, the front top plate is slidable, so it can function as an OA table when used. The present invention will be explained below based on the illustrated embodiment.

In the figure, reference numeral 1 denotes the main body frame of the desk, which, like a normal desk, consists of a chest and a top plate mounting frame above the legs.

The top plate provided at the top of the main body frame 1 is divided into a rear top plate 2 and a front top plate 3 in two, but the sizes of both top plates 2 and 3 are omitted in the illustrated embodiment. Although they are the same size, the rear top plate is suitable for placing a monitor TV and the front top plate is suitable for placing a keyboard, and when both top plates are flush, it can also be used for general office use. It shall be determined as appropriate.

This rear top plate 2 has brackets 4 and 4 on its underside.
The upper ends of the links 5 and 5 are pivotally connected to the brackets 4 and 4, respectively, and a screw rod 6 is provided on the main body frame and parallel to the rear top plate.
The right and left halves of this screw rod 6 are screwed in opposite directions from the center, respectively, and the lower end boss portions of the two links 5 and 5 are screwed onto the screw rods, and the screw rods are threaded outward from the main body frame. By rotating the provided handle 7, the boss portions 5a, 5a of the links are moved toward or away from each other, thereby raising and lowering the links 5, and raising and lowering the rear top plate 2.

A guide 9 is provided so that the rear top plate is always kept horizontal during this elevation. Further, the front top plate 3 is made to slide along outer rails 8 which are provided horizontally protruding from the top of the main body frame, and these outer rails 8 are provided horizontally below the top plates 2 and 3 on both sides of the main body frame. Along with this outer rail, rails 10 are arranged on both sides of the front top plate, and both rails support the front top plate so that it can slide freely in the horizontal direction, and guide grooves 11 provided on both rails. The guides 12 are fitted into each other and the top plate is slid by the length of the guide grooves, but deep grooves 11a are formed at both ends or in the middle of the guide grooves in which the guides are stably fitted.

In addition, there is an Ajiasuta 13 on the lower part of the main frame leg.
will be provided.

Therefore, according to the present invention, the top plate is divided into two parts, front and back, so that both the top plates are in a horizontal, flush state, and the rear top plate is provided so that it can be raised and lowered freely, and the front top plate is provided so that it can be slid in the front and rear directions. Therefore, it can be used not only for general office use but also for office automation. Especially when used for office automation, the top plate moves up and down or slides, allowing the user to set the TV, keyboard, etc. in the most convenient position. It has advantages such as improved performance and operability.
