Detailed Description

The invention is further described below with reference to the accompanying drawings.

As shown in the figure, the chair capable of inclining forwards and backwards and inclining leftwards and rightwards and twisting comprises a cushion 1, achassis 3, a cushion frontpoint connecting piece 2, a cushion rearpoint connecting piece 6, a right connectingpiece 5, a left connecting piece 7 and a slidingblock piece 10. The right connectingpart 5 and the left connecting part 7 can be of an integral structure or a split structure, and thebackrest 8 is connected to the right connectingpart 5 and the left connecting part 7.

Thechassis 3 may be a chassis of an existing swivel chair, and includes a damping torque output end (including a damping torque output structure) including arotating shaft 301 and atorque output shaft 302.

One end of the cushion frontpoint connecting piece 2 is arranged at two sides of thechassis 3 and is in running fit with thechassis 3, and the front part of the cushion frontpoint connecting piece 2 at the center of the cushion 1 is connected with the bottom of the cushion 1. The rear connectingpiece 6 of the cushion is fixedly connected with the damping torque output ends of thechassis 3 at two sides of thechassis 3, is specifically fixed with therotating shaft 301 and thetorque output shaft 302 of the damping torque output ends, and the rear connectingpiece 6 of the cushion is connected with the bottom of the cushion 1 at the rear part of the center position of the cushion 1. The cushion frontpoint connecting piece 2 and the cushion rearpoint connecting piece 6 are arranged on thechassis 3 in a front-back mode, namely the cushion frontpoint connecting piece 2 is arranged in the front of thechassis 3, and the cushion rearpoint connecting piece 6 is arranged on the rear of thechassis 3. The connection of the backpoint connecting piece 6 of the cushion and the bottom of the cushion 1 and the connection of the frontpoint connecting piece 2 of the cushion and the bottom of the cushion 1 all adopt universal rotary connection. The universal rotary connection is a conventional structure, for example, a connecting piece is adopted, the lower end of the connecting piece is connected with the rearpoint connecting piece 6 of the cushion through a rotating shaft, the upper end of the connecting piece is connected with the bottom of the cushion 1 through a rotating shaft, and the two rotating shafts are vertically matched on a plane so as to realize universal rotation. Of course, the universal rotary connection is not limited to be realized by rotating shafts in different directions, and can also be a universal ball structure.Point connecting piece 2 before the cushion and behind the cushionpoint connecting piece 6 andchassis 3, cushion 1, back 8's cooperation has realized the forward and backward function of inclining of chair, specifically is: the right connectingpart 5 and the left connecting part 7 are in sliding fit with thesliding part 4 and can slide mutually, but can transmit torque at the same time; when a user leans back, a backward force is applied to thebackrest 8, a torque formed by the force applied to thebackrest 8 is transmitted to the damping torque output end of thechassis 3 through thebackrest 8, the right connectingportion 5, the left connecting portion 7 and thesliding member 4, the damping torque of thechassis 3 is overcome, thebackrest 8, the right connectingportion 5 and the left connecting portion 7 rotate around the rotating shaft of thechassis 3, and meanwhile, the rearpoint connecting piece 6 of the seat cushion 1 is driven to rotate, so that the front and back leaning and leaning functions of the chair are achieved.

In order to realize the left-right inclined twisting of the chair, two sides of the damping torque output end of thechassis 3 are respectively and fixedly connected with thesliding part 4, and the right connectingpart 5 and the left connecting part 7 are respectively and elastically matched with thesliding part 4 in a vertical or vertical linear direction at a certain angle at two side parts of thechassis 3 in a sliding way.

As a preferred elastic sliding fit manner: the right connectingpart 5 and the left connecting part 7 are respectively provided with slidinggrooves 9 at two sides of thechassis 3, the upper and lower inner ends of thesliding grooves 9 are provided withelastic pieces 10, and thesliding piece 4 is limited in thesliding grooves 9 and is elastically matched with theelastic pieces 10 between the twoelastic pieces 10. Theelastic member 10 is preferably a spring. Theslider 4 is preferably of a slider construction. Theslider 4 is fixed with arotating shaft 301 and atorque output shaft 302 on a damping torque output end of thechassis 3 and is limited in thesliding groove 9. When the actual slidingmember 4 is installed, the slidingmember 4 and the cushion rearpoint connecting member 6 can be fixed together with the rotatingshaft 301 and thetorque output shaft 302 through the step screws, so that the installation cost is saved. In addition, the right connectingpart 5 and the left connecting part 7 are respectively hinged and matched with the bottom of the seat cushion 1 at the left and right sides of the rear part of the seat cushion 1.

The utility model discloses the principle of slope wrench movement about realizing as follows:

the cushion 1 has two connection points (called front and rear connection points) in tandem on the center line, namely the connection parts of the cushion 1 and the cushion frontpoint connecting piece 2 and the cushion 1 and the cushion rearpoint connecting piece 6. The seat cushion 1 has two connection points (referred to as left and right connection points) at the left and right sides of the rear portion thereof, namely, the connection portions between theright connection portion 5 and the seat cushion 1 and the connection portions between the left connection portion 7 and the seat cushion 1. The front and back connecting points of the cushion 1 only move back and forth along with the movement of thechassis 3, and are irrelevant to the force applied on the cushion 1. The left and right connecting points of the seat cushion 1 are elastically and slidably connected with thesliding piece 4 through the right connectingpart 5 and the left connecting part 7, so that the seat cushion can float up and down. That is, the central line of the cushion 1 is not active, and the left and right sides of the cushion 1 can move up and down under the action of force, that is, the cushion 1 can rotate left and right around the central line. When a person moves the center of gravity left or right on the seat cushion 1, for example, the person tilts to the right, the right connecting point floats downward. The left attachment point will float upwards and the seat cushion 1 will tilt to the right. Meanwhile, thebackrest 8 is driven to incline by the right connectingpart 5 and the left connecting part 7, so that the whole chair is inclined. Similarly, when a person leans backwards, thebackrest 8 drives the seat cushion 1 to tilt forwards and backwards, and if the center of gravity of the person leans to one side at the same time, the whole chair also tilts to one side.

As another embodiment, thesliding part 4 is fixedly connected with both sides of the rearpoint connecting piece 6 of the seat cushion, and the connectingpart 5 and the left connecting part 7 are respectively matched with thesliding part 4 in a vertical sliding way or a direction forming a certain angle with a vertical straight line in an up-and-down elastic sliding way at both side parts of thechassis 3, and the elastic sliding way is not changed. By adopting the structure, one end of the cushion rearpoint connecting piece 6 is arranged at two sides of thechassis 3 and is fixedly connected with the damping torque output end of thechassis 3, in particular to the rotatingshaft 301 and thetorque output shaft 302 of the damping torque output end, and thesliding pieces 4 are respectively fixed at two sides of the cushion rearpoint connecting piece 6. This embodiment also enables a side-to-side tilt twisting of the chair.

Of course, in order to form a complete chair, the chair of the present invention is equipped with the necessary components of the chair, such as chair legs, air pressure bars, etc.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
