Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a resilient chair, and more particularly to a resilient chair that can follow the occupant's posture, provides ergonomic support, is comfortable to sit in, and considers health.

[0002]

[Prior art]

 Traditionally, it is important for office workers and students who need to sit in a chair for a long time to select a chair that is comfortable and ergonomic. In general, a chair has a seating portion on which a person sits, a plurality of legs extending downward from the bottom thereof, and a backrest for supporting a back is provided on one side of the seating portion.

[0003]

[Problems to be solved by the invention]

 However, all types of chairs have the following disadvantages. That is, when sitting on a chair, the force applied to the buttocks is always constant no matter how the posture changes, so that a force is applied to a certain part of the buttocks for a long time, and as a result, not only the buttocks but also the waist and , Which can have a negative effect on the spinal cord.

[0004] The present invention has been made in view of the above-mentioned problem, and an annular frame member having an opening is provided on a leg portion of a chair, and an elastic sphere is fitted into the opening. Accordingly, it is an object of the present invention to provide an elastic chair that can ergonomically respond to a change in the posture of a seated person and can provide a large-area support force.

[0005]

[Means for Solving the Problems]

 A resilient chair according to the present invention forms an annular body having an opening, a frame member having a plurality of legs extending downward from a peripheral edge thereof, and a frame member having a diameter larger than the opening of the frame member. And a resilient sphere most of which is exposed above the opening.

[0006]

[Embodiment of the invention]

 Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is an exploded perspective view of the chair according to the present invention, FIG. 2 is a perspective view of the chair according to the present invention, and FIG. 3 is a partial rear sectional view of the chair according to the present invention.

As shown in FIGS. 1 and 2, a resilient chair according to the present invention has an annular frame member 10 having an opening 11 in the center, and extends downward from the bottom of the frame member 10. The four legs 12, the two supporting bars 13 erected at a predetermined distance above one side of the frame member 10, and the backrest 14 provided at the tip of the supporting bar 13. And an elastic sphere 20 partially fitted into the opening 11 of the frame member 10. The elastic sphere 20 has a diameter larger than the opening 11 of the frame member 10, and when one lower side is fitted into the opening 11 of the frame member 10, most of the elastic sphere 20 is exposed from the opening 11. ing.

The elastic sphere 20 is made of an airtight material, for example, rubber, soft synthetic resin, or a material obtained by implanting hairs on the surface thereof. Is formed.

When sitting on the chair configured as described above, as shown in FIGS. 2 and 3, the occupant places his buttocks on the upper surface of the elastic sphere 20 exposed from the opening 11 of the frame member 10. As a result, the elastic sphere 20 receives a pressing force over a wide range and is appropriately deformed according to the shape of the buttocks 30 to uniformly support the buttocks 30 and reduce concentrated stress applied to the buttocks 30. In addition, no matter how the posture of the occupant changes, the elastic sphere 20 deforms to follow the moving shape of the buttock 30 of the occupant, gives a uniform support force, and exerts an effect suitable for ergonomics. it can.

FIG. 4 is a perspective view showing another embodiment of the chair according to the present invention. FIG. 4 shows another embodiment of the chair according to the present invention. The chair has four legs 40, and a first frame member 41 is provided at an intermediate portion between the legs 40. At the same time, a second frame member 42 is provided at the distal end thereof. Openings 43, 43 for fitting the elastic spheres 20 are formed at the centers of the first and second frame members 41, 42, respectively, and the openings 43, 43 are smaller than the diameter of the elastic spheres 20, When the elastic sphere 20 is fitted to the first and second frame member members 41 and 42, a part of the elastic sphere 20 is exposed from above the second frame member 42. A backrest 44 is provided on one side of the second frame member 42.

[0011]

[Effect of the invention]

 Since the present invention has the above configuration, the following effects can be obtained. That is, by fitting the elastic sphere to the frame member, the elastic sphere can be deformed to follow the change of the posture of the occupant, and an ergonomic chair capable of providing a wide range of supporting force can be provided. It can relieve pain in the buttocks, hips and spinal cord due to fatigue from sitting for a long time and poor posture.
