Definitions

  • the invention pertains to the special furniture developed for workplaces, and is intended for use at organization of operators and dispatchers workplaces of various professions, and can be used also as school furniture.
  • the known models are designed for a user's normal bearing and consequently appear to be hardly effective for those which bearing is deformed as a result of work on armchairs and chairs intended for a conditions of life. Therefore the developers of special furniture offer such technical decisions which are directed on reduction of a nervous - muscular overstrain, exhaustions psychosensorial mechanisms of a human organism and reduction of probability of the appearance of occupational diseases.

  • the basis of the invention is the improvement of the chair - support in which, in consequence of performance of the hinge providing inclination of the rack, as the springing- loaded rod, on which the bottom end of the rack rests, thus the spring and the bottom end of the rack are located in the case, with external and internal conic surfaces placed in the basis of a chair - support, and execution of the spring-loaded rod with an element of a spherical surface, the possibility of inclination of the rack in any direction not tensile stress, but compression stresses in the design elements, is provided, and due to the simplification of the design and increase of its reliability is achieved.
  • the set task is solved so that in the known chair - support, containing the basis, the seat established on the basis by means of the rack, connected with a hinge to the basis with a possibility of its installation at various inclination angles to the basis, according to the invention, the hinge providing inclination of the rack, is executed as a springing rod, on which the bottom end of the rack rests, thus the spring and the bottom end of the rack are placed in the case with external and internal conic surfaces and placed in the basis of a chair - support, and the spring- loaded rod is executed with an element of a spherical surface.
  • the hinge providing an inclination of the rack, may be executed so, that the element of a spherical surface of one rod end is located inside its case and interacts with the end of the rack.
  • the hinge providing inclination of the rack, may be executed so, that the element of the spherical surface of other rod end is located outside of its case.
  • the solution has also the inventive level. It is known the basis of a chair [see the statement to the patent of the USSR M> 021 16742 published 21.12.93, IC1 A 47 B 91/00] in which its one internal wall is executed conic to prevent a lateral inclination and slipping of the rack downwards on the cartridge.
  • the offered technical solution essentially differs from known one not only excluding the certain rack slipping to the cartridge, but also allows a floating mode of the rack position concerning of the rack vertical axis.
  • the offered device not only allows to take a convenient position, but also induces to movements, directed to correction of bearing, trains a muscular corset, improves heart, brain, spinal and pelvic blood circulation.
  • the offered technical decision being simple and reliable, stimulates a reflex of the spine alignment, which arises on the suggested device as compensatory reflex reaction on the support fluctuations and possible fall down.
  • the appearing effect of alignment is similar to the reflexes arising at riding which define correct bearing of people regularly engaged in riding.

  • Figs. 2, 2a, 2b The hinge providing inclination of the rack, assembled and in working positions (the Example 1 ).
  • Figs. 3, 3a, 3b The hinge providing inclination of the rack, assembled and in working positions (the Example 2).
  • a chair - support (figs. 1, l a, 2a, 2b) contains the basis 1 , the seat 2, established on the basis by means of the rack 3, connected with hinge to the basis with a possibility of its installation at various angles to the basis (Figs la).
  • the rack 3 is executed with a possibility of its height control (not shown on figures).
  • the hinge 4, providing inclination of the rack 3, is executed as a spring-loaded rod 5, on which the bottom end of the rack 3 rests, thus tha spring 6 and the bottom end of the rack 3 are located in the case 7, having external 8 and internal 9 conic surfaces, and placed in the basis of 1 of chair- support.
  • the end of the rack 3 also is executed with a conic surface 10.
  • the spring-loaded rod 5 has an element of a spherical surface 1 1. Together with a spring 6 the rod 5 is fixed in the case 7 relatively to the end of the rack 3 with the help of a back nut 12. It is possible to carry out not only a floating mode of the device operation, but also to the fixed mode by simple regulation of a spring compression with the back nut 12.
  • the hinge 4, providing an inclination of the rack 3, is executed so, that the element of a spherical surface 1 I interacts with the end of the rack 3.

  • the hinge 4 providing an inclination of the rack 3, is executed so, that the element of the spherical surface 13 is located outside the case 7 and rests, for example, on the floor 14 of the room.
  • the device works as follows. As it is shown in figs. 2a, 2b, and also 3a, 3b, the backlash 15 appears at loading the rod 3 due to compression of a spring 6 between the end of a rod 3 and the case 7. There is a possibility to incline the rack 3 and seat 2, as shown in figs. 2b and 3b, to any side convenient for the user, because the bottom end of the rack 3 has a point contact with a spherical element of a surface 10 of rod 5 , or the spherical element of surface 13 has a point contact with the floor 14, at presence of a backlash 15 between the internal conic surface 9 of case 7 and conic surface 10 of the end of the rack 3.
  • the offered solution has a simple design, is capable to provide both a floating and fixed mode. It is reliable in operation and capable to provide long term of work, carrying out both its main function - a piece of furniture to sit on, and additional one - means for correcting of user's bearing.

Abstract

L'invention concerne un meuble spécialisé développé pour le bureau, qui est destiné aux postes de travail d'opérateurs et d'agents techniques dans divers métiers et peut s'utiliser comme meuble d'école. L'invention vise à améliorer le support de siège, dans lequel l'utilisation d'une charnière permet l'inclinaison du pied grâce à une tige précontrainte par ressort sur laquelle repose l'extrémité de fond du pied. Le ressort et l'extrémité inférieure du pied sont placés dans le boîtier, les surfaces coniques externes et internes étant placées dans la base du support de siège. La tige précontrainte par ressort comprend un élément à surface sphérique. Le pied peut être incliné dans n'importe quelle direction, les éléments de structure subissant non pas une contrainte de traction mais une contrainte de compression. Une conception plus simple permet une plus grande fiabilité. La solution proposée par l'invention se distingue par la simplicité de sa conception, et permet un mode flottant ou fixe. Le fonctionnement du siège est fiable, et il est capable de servir pendant longtemps en tant que meuble principal ou en tant que dispositif complémentaire destiné à corriger le maintien de l'utilisateur.
