Description

High-support chair

Technical Field

The utility model relates to a seat spare part technical field especially relates to a high support nature chair.

Background

In the existing chair, the structure of foam material, sponge and the like is generally directly provided as the buffer for providing comfortable seating; since a foam material or sponge is simply too soft and gives a sense of discomfort to a user, a spring is generally added to the foam material as a cushion in a large chair such as a boss chair. Such cushioning means will gradually fail as the foamed material ages, and will fail more rapidly especially when used too heavily for extended periods. Greatly affecting comfort and service life. Meanwhile, if a device such as a spring or a bracket is added to reduce the failure rate of the foaming material, the weight of the chair is greatly increased, which causes inconvenience in use. Further, the cushioning devices such as springs cannot effectively cushion the horizontal component force of the human body that is greatly moved when sitting or riding, but are likely to bend or break, resulting in a problem of support failure.

Detailed Description

The present invention is described in detail below with reference to the attached drawings:

as shown in fig. 1, 2, 3 and 4, a chair with high support performance comprises a quadrangular frame 1 made of plastic or aluminum, a support bottom plate 2 fixedly installed in the frame 1 through bolts, a support top plate 3 movably supported above the support bottom plate 2 through a first support 6 and a second support 7, and a sitting portion 4 made of soft materials such as latex or sponge and covering the support top plate 3 along the edge of the frame 1 for comfortable sitting, wherein the support bottom plate 2 and the support top plate 3 are both formed by injection molding. The frame 1 may be mounted to support members such as a five-star leg, a vehicle seat, a cross-type seat leg, and the like by means of a bolt and a buckle. The top of the supporting bottom plate 2 and the bottom of the supporting top plate 3 are symmetrically provided with ridge-shaped structures in a grid structure, and the ridge-shaped structures enclose and form rectangular accommodating cavities 5 distributed in a rectangular array. The receiving chamber 5 in this embodiment includes two rectangular frame arrays of 2 × 2 and 3 × 3 arranged at intervals inside and outside. The opposite upper and lower accommodating cavities 5 are internally provided with first brackets 6 which are distributed at intervals and used for providing vertical elastic support between the supporting top plate 3 and the supporting bottom plate 2, and second brackets 7 which are distributed at intervals and used for providing horizontal and vertical elastic support between the supporting top plate 3 and the supporting bottom plate 2. The first support 6 in this embodiment has eight (more or less in other preferred embodiments, preferably a distribution providing support of equal performance in each direction, centred symmetrically about the centre of the frame 1) distributed over four sides of the rectangular array of receiving cavities 5.

In this embodiment, the first support 6 includes a cylindrical shell 61 made of foam sponge and at least one cylindrical rubber spring 62 disposed in the shell 61, and the rubber spring 62 mainly bears the vibration in the vertical direction and the load of the human body, and has a good silencing effect because it is a structure in which the rubber layer wraps the cylindrical spring. When a human body sits, the edge of the top supporting plate 3 is the area with the largest bending after bearing pressure, and needs to adapt to the deformation thereof to provide elastic support (causing discomfort to the human body if the support is too hard), and in the embodiment, the rubber spring 62 is arranged on the four outer sides as the first support 6, so that the top supporting plate can have good support performance and quiet performance for adapting to the deformation with smaller elastic modulus and quiet characteristic. The four corners of the edge of the supporting top plate 3 are necessarily farthest away from the rectangular array of accommodating cavities 5, the deformation amount is also the largest, and the corners of the supporting top plate also have the strongest discomfort to the human body, so that at least four corners of the supporting top plate are required to be provided with the first brackets 6 for supporting.

In this embodiment, the second bracket 7 includes two bow-shaped elastic pieces 71 stopped at left and right, and in order to control the overall weight, the elastic pieces 71 are carbon fiber pieces in this embodiment. In other preferred embodiments where the weight parameter is not weighted, such as fixed seats and vehicle seats, the elastic sheet 71 may be made of a material with a longer service life, such as a spring steel plate. The arched tops of the elastic sheets 71 are oppositely connected to present an opposite X-shaped buffer member, and the opening directions of the elastic sheets 71 in the adjacent accommodating cavities 5 are mutually vertical, so that a rectangular coordinate system XY axial direction on a horizontal plane can efficiently resist and bear the load in the horizontal direction. The load applied from the vertical direction can also be loaded to a certain extent.

In this embodiment, the first abutting portion 72 of the bent plate shape extends outwards from the two arcuate ends of the elastic piece 71, and the first abutting portion 72 abuts against the wall surface and the bottom surface of the accommodating cavity 5, so that the elastic piece has a good contact surface with the accommodating cavity 5 and a limited level of freedom, and is not easy to slip, damage, fail and the like when bearing a load.

In this embodiment, the two elastic pieces 71 abutting against each other respectively extend oppositely to form a second abutting portion 73 at the abutting position, the second abutting portion 73 is in a platform shape, so that the two elastic pieces 71 are in surface contact, the surface contact makes the contact pressure between the two elastic pieces small when bearing a horizontal load, the two elastic pieces are not easy to damage, the surface contact also makes the two elastic pieces always keep in contact in a compression bearing process when bearing a vertical load, and the occurrence of failure problems such as sliding and loosening in the abutting state is reduced.

In this embodiment, the bottom of the accommodating cavity 5 is provided with a damping layer 51 made of soft elastic material such as rubber or TPU, and the damping layer is connected with the first bracket 6 and the second bracket 7, so that the friction force of the contact is increased to prevent the problems such as loosening and the like, and the isolation between the first bracket and the second bracket is realized to reduce wear.

In this embodiment, the supporting top plate 3 and the supporting bottom plate 2 are provided with a plurality of structure holes 52 distributed at the bottom of the accommodating cavity 5, and the structure holes 52 are used for reducing the weight of the supporting top plate 3 and the supporting bottom plate 2 as a whole.

In this embodiment, the sitting portion 4 is characterized by being wrapped around the outer side of the edge of the supporting roof 3 and extending downward into the gap covering the supporting roof 3 and the frame 1, thereby eliminating the gap that may cause discomfort to the human body.

The above embodiments are only described for the preferred embodiments of the present invention, and are not intended to limit the concept and scope of the present invention, and the various modifications and improvements made by the ordinary person in the art without departing from the design concept of the present invention all fall into the protection scope of the present invention.
