Description

Seat back, L-shaped arm and chassis integrated structure

The present invention relates to a chair structure, in particular to a seat back, an L-shaped arm and a chassis integrally formed structure.

According to the conventional chair, the seat cushion basically has a seat cushion which can provide the ride of the human buttocks, so that the leg is pressed by the support, and in order to match the height of the human body, a hydraulic rod is further arranged under the seat cushion. The seat cushion has a height adjustment function, and the majority of the chair set has a seat back, so that the upper body can lean against the back of the chair to improve the ride comfort. However, the seat cushion is used to connect the seat back and the oil pressure. The rod and its operating member are locked with a chassis at the lower end of the seat cushion, and the seat back and other members are respectively locked by the chassis. The assembly method is not only complicated in its overall structural arrangement, but also relatively assembled on the assembly. It also appears to be less convenient, so there is still room for improvement in its overall design.

In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the author has finally achieved a practical and practical creation.

The technical problem to be solved by the present invention is to provide a seat back, an L-shaped arm and a chassis integrally formed structure in view of the above-mentioned shortcomings existing in the prior art.

The chair body is integrally formed of a plastic material, the seat body is formed with a chassis, and an L-shaped arm is extended from the chassis. The L-shaped arm is hollowed out with a plurality of reinforcing plates, and the reinforcing plates are parallel to each other, and Forming an angle greater than or less than the angle of the L-shaped arm, the end of the L-shaped arm is formed with a seat back, a surface of the back of the seat is fixed, a through hole is formed in the center of the chassis, and a metal is embedded in the hole a ring, wherein the chassis is recessed toward the back of the chair, and the receiving groove is communicated from the outside to the perforation, and is adjacent to the perforation position. a plurality of screw holes are disposed in the chassis, and the plurality of screw holes are connected to the chassis, and a plurality of wheel bodies are coupled to one end, and a hydraulic rod is extended to the other end, and the oil rod is formed at the end of the oil rod a taper portion and a push button, the tripod is inserted into the perforation of the chair body with a hydraulic rod, and the taper portion and the metal ring form a tapered surface, and a handle is formed at one end of the handle, and the other is a pressing portion is formed at one end, and a control rod is disposed adjacent to the pressing portion, and the control handle is disposed at the receiving groove of the seat body, so that the pressing portion is in contact with the pressing button of the tripod, and The shaft is accommodated in the rotating shaft groove to form a pivot of the control handle, and a seat cushion is fixed to the chassis position by a plurality of bolts passing through the screw holes of the seat body.

The first main purpose of the creation is that the seat body is integrally formed of a plastic material with a chassis, an L-shaped arm and a seat back, which can save assembly steps between the chassis, the L-shaped arm and the seat back, thereby reducing the assembly step. Assembly components and assembly time, to achieve the practical effect of easy assembly.

The second main purpose of the present invention is that the L-shaped arm has a plurality of reinforcing plates at the hollow space, and the reinforcing plates are parallel to each other, and form an angle larger than the angle of the L-shaped arm and less than the degree, thereby having an L-shaped shape. The structural strength and lightweight effect of the arm.

Other objects, advantages and novel features of the present invention will become more apparent from the detailed description and the accompanying drawings.

In order to enable your review committee to have a better understanding and understanding of the purpose, characteristics and efficacy of this creation, please follow the following [simplified description of the drawings] as follows: First, please refer to Figure 1, Figure 2 and Section 3. As shown in the figure, a seat back, an L-shaped arm and a chassis integrally formed structure include: a chair body 10, a tripod 20, a control handle 30 and a seat cushion 40, and a chair body 10 Made of plastic material, the chair body is 10 A chassis 11 is formed, and an L-shaped arm 12 is extended from the chassis 11. The L-shaped arm 12 is hollowed out with a plurality of reinforcing plates 121. The reinforcing plates 121 are parallel to each other and form an L-shaped arm 12. There is an angle of more than 10 degrees and less than 80 degrees, so as to combine the structural strength and weight reduction effect of the L-shaped arm 12, the end of the L-shaped arm 12 is formed with a seat back 13 , and a surface 131 is fixed on the surface of the seat back 13 . A through hole 14 is defined in the center of the chassis 11 , and a metal ring 15 is embedded in the through hole 14 . The chassis 11 is recessed toward the seat back 13 and has a receiving groove 16 , and the receiving groove 16 is communicated from the outside to the through hole 14 . And a rotating shaft groove 17 laterally overlapping the receiving groove 16 is disposed at a position adjacent to the through hole 14. The other chassis 11 is provided with a plurality of screw holes 111. The one leg frame 20 is connected with a plurality of wheel bodies 21 at one end. And a hydraulic rod 22 is extended to the other end, and a tapered portion 221 and a pressing button 23 are formed at the end of the hydraulic rod 22, and the footrest 20 is inserted into the through hole 14 of the seat body 10 with the hydraulic rod 22 And the tapered portion 221 and the metal ring 15 form a tapered surface, and a handle portion 30 is formed with a grip portion 31 at one end thereof, and The other end is formed with a pressing portion 32, and the control handle 30 is disposed adjacent to the pressing portion 32 at a position of a shaft 33. The control handle 30 is disposed at the receiving groove 16 of the seat body 10, and the pressing portion 32 is disposed. The shank of the handle 20 is formed by a plurality of bolts 41 passing through the screw hole 111 of the seat body 10. Fixed to the chassis 11 position.
