Abstract

The utility model relates to a rotary cushion which is composed of an upper circular ring, a lower circular ring, rolling balls, a curved seat panel and a soft bag layer. The upper circular ring and the lower circular ring which are buckled with each other oppositely can be rotated oppositely via the rolling balls between the upper circular ring and the lower circular ring. The utility model which can be arranged on common chairs and stools has the function of free rotation. The utility model has the advantages of convenient use and comfort sitting.

Description

Rotary cushion

The utility model is a kind of seat cushion.A kind of Rotary cushion with rotating function.

Up to now, chair, stool seat cushion are all made with flexible material, and the people is sat with comfortable.But when the people rotated, friction was big, rotated dumb.

The purpose of this utility model is to provide a kind of movable being placed on common chair, the stool, and can realize rotating function, and comfortable novel seat cushion is seated.

The purpose of this utility model be achieved in that the cross section be convex last annulus (3) and cross section matrix following annulus (5) mutually make-up put, the centre is provided with ball (4), forms rotating disk.Last annulus (3) top is provided with the bent seat surface plate (2) of concave Iy curved, paste sponge above the bent seat surface plate (2), wrap again with layer of cloth and form Soft Roll layer (1), because upper and lower two parts are rotatable, so bent seat surface plate (2) can be made into the bent seat surface plate of the matrix of human leg, the bending of buttocks sitting posture, thereby increased the contact area of human body and panel, reduced the pressure of human body, indefatigability so sitting is comfortable.

Figure (1) is the utility model planform schematic diagram.

Figure (2) is a cutaway view of the present utility model.

Wherein: (1) Soft Roll layer; (2) bent seat surface plate; (3) go up annulus; (4) ball; (5) annulus under; (6) pin screw;

Below in conjunction with description of drawings cutaway view of the present utility model.

Structure content is seen accompanying drawing 1,2, and its structure is by Soft Roll layer (1), bent seat surface plate (2), last annulus (3) cross section is a convex, following annulus (5) cross section is a matrix, two annulus phase make-ups are put, and the centre is provided with ball (4), and upper and lower two annulus do not break away from it after by screw (6) precession.Two annulus materials can be made of plastics or metal.Its diameter is about between the 200-300mm is advisable.The available plain ball of ball (4).Connect with plastics or metal bent seat surface plate (2) above the last annulus (3).Bent seat surface plate (2) upper surface pastes sponge and the infantees bed of material is formed Soft Roll layer (1), and bent seat surface plate (2) upper surface is designed to the concave Iy curved that adapts with the buttocks sitting posture, to increase the contact area with human body, reduces pressure.When the people takes when rotating health, annulus in the drive (3), bent seat surface plate (2) rotates by ball (4) with human body and following annulus (5).Realized rotating function.

Characteristics of the present utility model are: simple in structure, easy to use, rotate freely. Can alleviate the sitting sense of fatigue.
