This application is a U.S. national stage application of an international application PCT/RU2012/000531 filed on 3 Jul. 2012, published as WO/2013/006097, which international application claims priority of a Russian Federation patent application RU2011127063 filed on 4 Jul. 2011.
The invention relates to articles of educational furniture and can be used for organized learning.
The most close to the proposed invention is the study desk (patent of France WO 02/069756 A1, cl. A47B39/02, Dec. 9, 2002), comprising a worktop, and the worktop is formed with the possibility of changing the angle of incline and moving towards the student. The distinction of the claimed invention is the structure of the worktop which implies simultaneous tilt and transfer of the worktop. Tilt and transfer of the worktop in the said closest analogue are carried out independently: the transfer of the worktop is fulfilled along the guides mounted on a supporting framework, and the tilt of the worktop is fulfilled with the aid of the rotation about the horizontal axis in the level of the guides.
In the claimed invention, the tilt and transfer of the worktop are carried out simultaneously by means of rotation of the worktop, connected by a hinged joint, composed of two horizontal axes, to two horizontal axes of a supporting framework, via two essentially planar pivotal panels of different widths, describing circles of different radiuses during rotation. The advantage of this design is a reduction of the number of a user's actions, aimed at the achievement of the requisite result.
The essence of the invention is that in a tiltable worktop connected to a supporting framework by a hinged joint, the hinged joint between the worktop and the supporting framework is formed via two pivotal panels of different widths.
The aim of the invention is an improvement of writing tables and study desks with a worktop which can be tilted and moved by means of a single action of the user.
While the invention may be susceptible to embodiment in different forms, there will be described in detail herein, specific embodiments of the instant invention, with the understanding that the present disclosure is to be considered an exemplification of the principles of the invention, and is not intended to limit the invention to that as illustrated and described herein.
The structure of the inventive worktop is illustrated in the drawings, wherein:
The structure comprises: a worktop (1) (
The worktop (1) is attached via a first axis (2) to the pivotal panel (4) being connected via a second axis (2) with the frame (3); the worktop (1) is attached via a third axis (2) to the pivotal panel (5) being connected via a fourth axis (2) with the frame (3). A first limit stop (6) is secured on the left side of the frame (3), and limits the rotation of the pivotal panel (4); whereas a second limit stop (6) is secured on the right side of the frame (3), and limits the rotation of the pivotal panel (5). The rotatable handle (7) is immovably mounted on the pivotal panel (4) to provide moving the worktop (1) by one hand of the user.
When the handle (7) (
The requisite result of the use of the proposed study desk worktop is that, by a single movement of the handle, the worktop is transferred from a horizontal into a tilted position while the edge of the worktop is brought closer to the student.
