Embodiment 1

[0029] A seat system for sitting and reclining, such as figure 1 As shown, it is made up of front leg tube system 10, rear leg tube system 20, steel ball 30, spring 40, seat surface 50, backrest 60, front leg seat wheel 70 and rear leg seat wheel 80. figure 2 yes figure 1 A partially enlarged schematic diagram. Described front leg tube system 10 is as image 3 As shown, it is made up of foot pipe 11, upper cross pipe 12, spring 13, cross pipe 14 and triangular piece 15. Wherein, the said leg tube 11 is as Figure 4 As shown, there is a through hole 111 on its top, the bottom is closed, a threaded hole 112 is arranged, and a threaded hole 113 is arranged in the middle. There are two pin tubes 11. The upper horizontal pipe 12 is as Figure 5 As shown, there is a rectangular hole 121 at one end, and a large through hole 122 is arranged in the middle of the side wall of the rectangular hole 121, and a pin is connected to the large through hole 122 . The other end has a rec...

Embodiment 2

[0032] Figure 11 Shown is another kind of implementation of the technical solution, and its difference with the first solution is: one, the front foot seat wheel 70 and the rear foot seat wheel 80 are replaced by castor wheels 90 (or universal wheels). 2. The leg tube 11 of the front leg tube system 10 and the upper horizontal tube 12 are bent from the same tube. Three, the foot pipe 11 of the rear foot pipe system 20 is welded together with the backrest pipe 21.

Abstract

The invention discloses a seat system capable of sitting and lying, which is characterized by consisting of a front leg system, a rear leg system, steel balls, a spring, a seat surface, a backrest, a front foot stand wheel and a rear foot stand wheel; a horizontal pipe on a backrest pipe of the rear leg system is inserted into an upper horizontal pipe of the front leg system so as to realize sliding connection through the steel balls in recesses on respective pipe walls; a hole of the horizontal pipe on the backrest pipe is connected with a rectangular hole of the upper horizontal pipe through the spring; the backrest is hinged with two through holes of the backrest pipe through a rear hinge; and the rear foot stand wheel and the front foot stand wheel are connected with the front leg system and the rear leg system through threads respectively. The seat system has the advantages that: a user can sit and lay on the seat, and the center of gravity is automatically adjusted simultaneously.

Description

technical field [0001] The invention belongs to the technical field of furniture products, in particular to a structure of a seat system. Background technique [0002] Most of the existing seat systems can only sit, not lie down. Certain reclining seating systems utilize the reclining of an adjustable backrest. But its shortcoming is: one, " can only sit, can not lie down " seat system is unfavorable for people's noon rest. 2. The center of gravity of the seat system "realized by reclining the adjustable backrest" is fixed and not adjustable, so the reclining angle of the backrest is limited, or a larger chassis is required to increase the range of the center of gravity. Contents of the invention [0003] The object of the present invention is to provide a seat system that can be used for sitting or lying down, and can automatically adjust the center of gravity at the same time. [0004] In order to achieve the above object, the technical solution of the present inventi...
