Description

  TECHNICAL FIELD The present invention relates to a top / bottom desk that can change the height of a top plate in the vertical direction in response to a request from a worker in a work space such as an office or a public facility.

  In office spaces such as offices and public facilities, a desk device (desk) is generally provided to provide a work area to the office worker. The height of the desk top, which is easy to work with, depends on the physique, gender and preferences of the workers. In such an actual situation, a desk device with a fixed top plate height cannot be used, and therefore a top plate lifting desk that allows the top plate height to be changed in the vertical direction is used. By using such a top-and-bottom desk, it is possible to provide a work area with a top-height that meets the demands of the worker, improving work efficiency and reducing the burden on the worker's body. Can do.

  As means for changing the height of the top plate in the vertical direction, a method using a gas spring, a method using a gear, and the like have been invented (for example, see Patent Documents 1 and 2). According to these methods, the structure can be made relatively simple and the cost can be reduced. Moreover, in order to improve the operability of the office worker, many methods using an electric lifting mechanism unit are employed (see, for example, Patent Documents 3 to 5). According to this method, the office worker can change the height of the top board with an easy operation.

In a top-and-bottom desk, a desktop panel (rear auxiliary member) is arranged at the end of the top plate (particularly, the end of the top plate opposite to the side used by the office worker). In many cases, the work space on the top plate is separated from other spaces, and the article placed on the top plate is prevented from falling when the top plate is raised or lowered.
In such a structure, it is necessary to dispose the desktop panel so as to contact or approach the end of the top plate for the purpose. However, there is no gap between the end of the top panel and the desktop panel (there is little), so there is a problem that the wiring cannot be inserted between the top panel and the desktop panel. There is a problem that an option (accessory part such as a small shelf) cannot be attached by gripping by the above.
