Description
A kind of desk of forming by the bracing frame of desktop, table bucket and height-adjustable, especially a kind of desk that has the sighting distance limiter of height-adjustable.The invention still further relates to a kind of and the supporting chair of desk, form, belong to bracing frame and depart from the chair at seat plate center by the plane bearing support seat plate and the strong point by the chair bracing frame of chair back, seat plate and height-adjustable.
The desk that uses in people's daily life is the desk of the device of no any restrictive sight distance mostly.This is easy to cause the generation and the development of myopia concerning the people of long-time study and work.Recently design has the desk with sighting distance restraint device, as Chinese patent ZL94240720: the adjustable health care table of teaching, a kind of table of teaching with locator is disclosed, its locator is restrictive sight distance to a certain extent, but the mode of this restrictive sight distance allows the user produce fatigue easily, is unfavorable for the use of long period; And the height of limiter can not be regulated, and can't adapt to the user of different heights best, and its supporting chair does not take into full account the comfortableness when using yet.
In order to improve above-mentioned shortcoming, the utility model provides a kind of health care desk.It not only can allow user's sighting distance obtain restriction, and the backup plate of desk is available for users to the shirtfront cosily by thereon, helps the user and uses for a long time and but be difficult for feeling tired.In addition, in order to guarantee and reduce cost that be fixed with a scale on the table bucket of the present utility model, desktop is the integral body that two intersecting planes constitute easy to use, available steel plate or nonmetallic materials are one time punching molded.For guaranteeing matching used comfortableness, the utility model also provides a kind of eccentric chair that can rotate arbitrarily.
In order to achieve the above object, the limiter of a restrictive sight distance has been fixed in the desktop front of sight protection table of the present utility model, limiter is made up of backup plate, connecting plate and L type support. and backup plate is available for users to easily by thereon, backup plate and connecting plate are hinged and connected, the two is fixed in the vertical operative tip of L type support together, porose on the connecting plate, it is fixed on place, different hole, can regulate it and be fixed on height on the L type support; Also porose on the L type support, L type support level part is fixed in the different holes with desktop, can regulate the length that it stretches out desktop, that is to say the horizontal range of regulating backup plate and desktop. the sighting distance the when adjusting of two places combines and can limit the user very effectively and use, desktop is an integral body, and the table bucket has scale.
In addition, for matching used flexibility and comfortableness, the support end that the bracing frame of the matching used chair of the utility model supports the seat plate is equipped with a plane bearing, the seat plate can arbitrarily be rotated, the strong point of seat plate is located at the position of departing from its center, can be sitting in easily when using like this and turn round on the chair and, make the use of tables and chairs be more suitable for physiologic habit in the people away from desk.
From the above, the desk that the utility model provides can guarantee that people are keeping suitable sighting distance in the study or the course of work for a long time, movable backup plate can be for the user for a long time by avoiding cervical vertebra thereon, each joint of vertebra and arm and even whole body produce tired, one time punching molded desktop can reduce manufacturing cost, the tables and chairs height that scale on the table bucket can instruct people to be adjusted to adapt with own height, the eccentric chair that can arbitrarily rotate is had a rest away from desk after greatly facilitating long-time study of user or work on the spot.Therefore, tables and chairs of the present utility model are simple in structure, and are with low cost, and suitable ages are wide, fatigue and near-sighted generation and the development that can avoid long-time study or work to bring effectively.
Concrete structure of the present utility model will describe in detail with embodiment in conjunction with the following drawings.
Figure one is the front view of sight protection desk;
