Description

[Detailed explanation of the invention] [Industrial application field] This invention relates to desks for office equipment, etc., and more specifically, for example, personal computers, word processors, etc., with display devices, keyboards, and image readers. This relates to the improvement of desks used for so-called office automation equipment (OA equipment) or for general writing work.

[Prior Art] A commonly used desk is known to have a single work top plate attached to the top of the support legs, and dictionaries and reference books are generally placed on the depth side of the work top plate. It is used with a book stand for books such as books and other necessary stationery placed on it.
Furthermore, as a desk for office automation equipment consisting of a display device, a keyboard, etc., one is known that is equipped with a top plate section for placing the display device and a top plate section for placing the keyboard. In the desk, the top plate for placing the display device is mounted above the top plate for placing the keyboard.

[Problem to be solved by the invention] However, in desks for OA equipment, the top plate part for placing the display device and the top plate part for placing the keyboard are fixedly attached, so the display device and the top plate part are fixed. There is a problem that the position of the keyboard is not optimal for the operator, causing excessive fatigue to the operator, especially when working for a long time.Furthermore, although it differs slightly depending on the model, generally the display device and the keyboard are Due to the distance between the two machines, the operator must frequently move his/her line of sight while working.
In this respect as well, there was a problem in that it caused operator fatigue. In addition, in a general desk with a single work top, the writing section and the section on which book stands are placed are on the same plane, so books such as dictionaries and stationery can be placed on the same plane while writing. There was a problem that it was troublesome to take out.

This invention was made with the intention of solving the above problem, and its purpose is to reduce the fatigue level of operators, etc. during writing work and work on OA equipment as much as possible. Moreover,
The object is to provide a desk for office equipment, etc., which has a simple structure and is easy to handle.

[Means for Solving the Problems] In order to achieve the above object, this invention includes: a pair of supporting legs that are erected to face each other with a predetermined interval left and right; A desk for office equipment, etc., comprising two top plates divided into two parts, front and back, and two supporting means for separately supporting each top plate so as to be movable up and down relative to support legs. In the above, the support means is a member having an inverted L-shape on the side that supports each of the front and rear top plates at the end of the divided side, and is a top plate support member that is attached so as to face the center of each top plate. a screw shaft that is rotatably supported by the pair of support legs in the left-right direction and has a reverse threaded portion at both ends; and a pair of sliding members that are screwed onto the screw shafts, respectively. a pair of link members that connect the pair of sliding members and the lower end of the top plate support member to each other; and a pair of link members that transmit rotational force to the ends of the screw shaft in 90 degrees different directions. The above-mentioned device comprises an operating shaft provided with gears for rotating the screw shaft which is projected toward the front of the desk via the set of gears, and an operating handle provided at the tip of the operating shaft. A support means for vertically movably supporting the front top plate and a support means for vertically movably supporting the rear top plate are arranged in close proximity to each other in the front and back between a pair of support legs, and each of the above-mentioned support means An object of the present invention is to provide a desk for office equipment, etc., characterized in that both operation handles are arranged facing the front of the desk.

Furthermore, the support means for at least one top plate,
It can also be formed to be horizontally slidable and/or vertically adjustable.

In this invention, the support means may be of any type as long as it supports each top plate in a position-adjustable manner, such as a plurality of locking slits bored at appropriate intervals in the height direction of the support legs. , and a bracket that has a locking portion that engages with any part of these locking slits and supports the top plate.

In addition, when the support means is equipped with an elevating mechanism, for example, in addition to a mechanical elevating mechanism having a conversion mechanism that converts rotational motion by a handle into linear motion, a fluid pressure called a gas spring is used as the elevating mechanism. Any item can be used.

In addition, when the top plate is formed to be horizontally slidable and/or vertically adjustable in angle, at least one of the top plates is horizontally slidable, vertically adjustable in angle, or
Any type of support means may be used as long as it is horizontally slidable and vertically adjustable; for example, a support base that allows the support means to be attached to a support leg in a position adjustable manner (including that it can be raised or lowered), and a A movable part that supports and fixes the top plate and is attached so as to be horizontally slidable and/or vertically adjustable in angle.

[Effect] The above technical means works as follows.

This device is equipped with two support means that separately support each top plate so that it can move up and down relative to the support legs, so the two top plates can be adjusted to any height position relative to the support legs. Since it can be used in an appropriate state according to the purpose of use, it is possible to improve work efficiency and reduce fatigue of the user.

Further, the two supporting means for separately supporting each of the top plates in a vertically movable manner relative to the support legs are members having an inverted L-shape on the side that support each of the front and rear top plates at the end of the divided side. Since it is equipped with a top plate support member that can be attached so that the center of each top plate faces the other, it is possible to separate the two top plates separately, as in the case where the front and rear top plates are supported at their center.
