DETAILED DESCRIPTION

[0022] The utility model will be further explained in detail in combination with the drawings.

[0023] To solve the above technical problem, the technical scheme provided by the utility model is: a kind of restaurant card seat structure, in combination withFigures 1-3 , including the chair frame 1, the top of which is connected with a backrest 2, and one side of the chair frame 1 is provided with a seat, which includes an inner seat plate 9 in the middle and two outer seat plates 5 on both sides;

[0024] The card seat is usually made of pure wood in the restaurant decoration site, or made of wood and steel plates in the factory. The structure of the card seat is suitable for the above two common card seat forms;

[0025] The seat part of the card seat is divided into two movable parts, the inner seat plate 9 and the outer seat plate 5. According to the expected number of people carried by the card seat, the following combinations can be used:

[0026] One inner seat plate 9 is placed against the wall, and one outer seat plate 5 is placed near the aisle;

[0027] One inner seat plate 9 is installed in the middle of the card seat, and two outer seat plates 5 are arranged on both sides, as shown in the product style in the attached drawings of the specification;

[0028] Two inner seat plates 9 are placed opposite to each other in the middle of the card seat, and one outer seat plate 5 is installed on each side. At this time, the card seat needs to be arranged between two aisles in the restaurant;

[0029] The chair frame 1 is provided with a sliding assembly that can change the position of the inner seat plate 9 by sliding. The sliding assembly includes a sliding rail 7 installed on one side of the chair frame 1. The end of the inner seat plate 9 is connected with a sliding carriage 8 that is slidably connected with the sliding rail 7. The bottom of the sliding carriage 8 is provided with a clearance groove 11 that cooperates with the outer seat plate 5. The end of the sliding carriage 8 extends beyond the sliding rail 7 and is connected with a support plate 10 that is attached to the chair frame 1 on the side away from the seat;

[0030] The inner seat plate 9 is installed in a slidable state in the chair frame 1. The sliding carriage 8 and the sliding rail 7 are installed between them. The inner seat plate 9 can be moved to the side near the aisle by sliding. After the person sits down, it can be moved back to the middle position of the chair frame 1 by sliding. The person does not need to crouch to enter the deep area between the card seat and the table, and then sit down. The support plate 10 connected to the sliding carriage 8 after extension and closely attached to the back of the chair frame 1 can assist the inner seat plate 9 to effectively bear the weight of the person sitting on it;

[0031] The attached drawings Figure 4The chair frame 1 and the support plate 10 are connected together by a locking mechanism for fixing the position of the inner seat plate 9. The locking mechanism includes a cover 12 installed on the side of the chair frame 1 away from the seat. The cover 12 is connected with a plurality of pin holes 13. The support plate 10 is connected with a plurality of hollow sliding columns 14. The sliding columns 14 are equipped with spring buckles 15 that cooperate with the pin holes 13 and have spherical ends.

[0032] The sliding inner seat 9 is not secure, which will affect the comfort of the person sitting on it. Therefore, a locking mechanism with spring buckles 15 as the main component is set. The spring buckles 15 are inserted into the pin holes 13 of the cover 12 to fix the position of the inner seat 9. According to the reasonable size setting, when the inner seat 9 is moved to one end of the seat, one of the spring buckles 15 is also inserted into one of the pin holes 13 of the cover 12 to fix the position. The end of the spring buckle 15 is spherical. When the person sitting on the inner seat 9 applies a little force, the inner seat 9 can be unlocked and moved and changed position at will.

[0033] Combined with appendix Figures 1-4 The chair frame 1 is equipped with a retractable assembly that allows the outer seat plate 5 to be retracted by rotation, thereby making room for the inner seat plate 9 to slide. The retractable assembly includes a support column 3 connected inside the chair frame 1 and supporting the outer seat plate 5 for rotational connection. A support shaft 4 is connected to the bottom of the chair frame 1. A hydraulic telescopic rod 6 is rotatably connected between the outer seat plate 5 and the support shaft 4.

[0034] The top surfaces of all the seat panels on the chair should be aligned to ensure comfortable use. In order to prevent the outer seat panel 5 from blocking the movement of the inner seat panel 9, a hydraulic telescopic rod 6 is installed at the bottom of the chair frame 1. The hydraulic telescopic rod 6 is used to shorten and rotate the outer seat panel 5 downward, thereby making room for the movement of the inner seat panel 9. After rotation, the end of the outer seat panel 5 is retracted downward, which also prevents the back of the lower leg from being bumped when people enter the area between the table and the chair.

[0035] In practical implementation of this invention, when diners sit in the booth, the person who intends to sit on the inner side of the seat is first allowed to sit down. At this time, the inner seat plate 9 is pulled down to the edge of the seat near the aisle. The person sits on the inner seat and moves into the seat by using the force of their legs, buttocks, or upper limbs in coordination. After they are seated, the outer seat plate 5, which is located on the lower outer side of the booth, is rotated back to a horizontal state that is flush with the inner seat plate 9 by the extension of the hydraulic telescopic rod 6. The remaining person can then sit down. When the customer in the booth wants to get up, the process is reversed to allow all people to get up easily.

[0036] The above has described the utility model and its implementation mode, which is not restrictive, and the drawings only show one of the implementation modes of the utility model, and the actual structure is not limited thereto. In summary, if a person skilled in the art is inspired thereby, without departing from the creative purpose of the utility model, similar structural modes and embodiments are not creatively designed, which should belong to the protection scope of the utility model.
