Description

Technical Field

[0001] This utility model belongs to the field of seating design technology, and in particular relates to a waiting chair seat. Background Technology

[0002] In modern public environments, such as waiting rooms, airports, or hospitals, chairs for waiting people are indispensable facilities. The design of these chairs must not only consider comfort, but also meet the needs of different usage occasions and groups of people.

[0003] However, when using existing waiting chairs, the seats are usually L-shaped. When users sit on L-shaped seats for a long time, their legs are in a compressed state for a long time, which can lead to numbness, swelling and other discomfort in the legs, thus reducing the comfort of users when sitting on such seats.

[0004] In other words, when users sit on the seat of a traditional waiting chair for a long time, their legs are in a compressed state for an extended period, which affects the comfort of the user. Utility Model Content

[0005] This invention addresses the problem that prolonged sitting on traditional waiting chairs in the prior art results in users' legs being constantly compressed, thus affecting their comfort. The following technical solution is proposed:

[0006] A waiting chair seat surface, comprising:

[0007] The crossbeam is equipped with multiple support bases;

[0008] The support feet are connected to the crossbeam and are used to support the crossbeam.

[0009] Handrails are connected to the crossbeams;

[0010] The seat is connected to the crossbeam via a support base. The seat has a backrest, and both the seat and the backrest have multiple grooves. The backrest is inclined counterclockwise with the connection point with the seat as the center. Both the seat and the backrest have horizontal and vertical reinforcing ribs to enhance the overall structural strength of the seat and the backrest.

[0011] As a preferred embodiment of the above technical solution, it further includes: a connector, a rhombus-shaped mounting base, a rotating shaft, a mounting component, and a limiting component. The rhombus-shaped mounting base is connected to the handrail via the connector, the handrail is connected to the rotating shaft, and the limiting component and the mounting component are connected to the handrail and the rhombus-shaped mounting base via the rotating shaft. The limiting component and the mounting component enable the rotating shaft to change from a rotating state to a stationary state.

[0012] As a preferred embodiment of the above technical solution, the number of handrails is set to multiple, and they are distributed in an equidistant array from one end of the crossbeam to the other end.

[0013] As a preferred embodiment of the above technical solution, a single seat surface is located between two adjacent armrests.

[0014] As a preferred embodiment of the above technical solution, the limiting member is provided with a handle, which is located below the limiting member and is used to drive the limiting member to rotate.

[0015] The pivot is in contact with the inner wall of the handrail.

[0016] The beneficial effects of this utility model are as follows:

[0017] (1) By tilting the backrest and seat in a counterclockwise direction, the user can reduce the force on the user's legs when sitting on the device for a long time. The grooves on the surface of the seat and the backrest increase the friction between the user's buttocks and back and the seat and backrest, thereby avoiding the symptoms of numbness and other discomfort in the user's legs when sitting on the waiting chair, thus improving the user's comfort when sitting on the waiting chair.

[0018] (2) By changing the connection method between the crossbeam and the armrest and the diamond mounting base, the disassembly or installation process between the armrest and the diamond mounting base and the crossbeam is simplified, which facilitates the maintenance or replacement of the armrest or the diamond mounting base in the later stage, thereby shortening the maintenance work of the waiting chair.

[0025] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0026] Example 1

[0027] This utility model provides a waiting chair surface, such as Figures 1 to 5 As shown, a waiting chair includes: a crossbeam 1, legs 2, armrests 3, and seat 4. The crossbeam 1 has multiple support seats, which are made of high-quality cold-rolled steel plates formed by stamping and bending for easy assembly with the crossbeam 1. The legs 2 are connected to the crossbeam 1, and each leg 2 has a foot pad for supporting the crossbeam 1. The armrests 3 are connected to the crossbeam 2 and are formed by bending elliptical tubes. Multiple seat seats 4 are provided, connected to the crossbeam 1 via support seats. The crossbeam 1 is made of square steel tubing. A backrest 5 is provided on the seat seat 4, and openings are provided on both the seat seat 4 and the backrest 5. There are multiple grooves. The backrest 5 is tilted counterclockwise with the connection point with the seat 4 as the center. Both the seat 4 and the backrest 5 are provided with horizontal and vertical reinforcing ribs. The seat 4 and the backrest 5 are integrally injection molded from ultra-tough polypropylene material to enhance the overall structural strength of the seat 4 and the backrest 5. The number of armrests 3 is set to multiple and is distributed in an equidistant array from one end of the crossbeam 1 to the other end to block multiple seat surfaces 4. Each seat surface 4 is located between two adjacent armrests 3, and the surfaces of the crossbeam 1, armrests 3 and legs 2 are all sprayed with electrostatic powder.

[0028] By tilting the backrest 5 and seat 4 counterclockwise, the backrest 5 reduces the stress on the user's legs when sitting on the device for a long time. The grooves on the surface of the seat 4 and backrest 5 increase the friction between the user's buttocks and back and the seat 4 and backrest 5, thus preventing the user from experiencing numbness, swelling and other discomfort in their legs when sitting on the waiting chair for a long time, thereby improving the user's comfort when sitting on the waiting chair.

[0029] When in use, the user sits on the seat 4, and the pressure from the user is transmitted to the crossbeam 1 through the support seat. The crossbeam then transmits the pressure to the ground through the footrests 2 on both sides, reducing vibrations. The user then leans against the backrest 5 for added comfort. The friction between the grooves on the seat 4 and backrest 5 and the user's buttocks and back provides stability and prevents slipping during extended use. The counter-clockwise tilt of the backrest 5 and seat 4 reduces pressure on the legs during long periods of use, and the grooves increase friction between the user's buttocks and back, preventing numbness, swelling, and other discomfort in the legs, thus improving overall comfort.

[0030] Specifically, both sides of the crossbeam 1 are connected to the foot 2, and multiple armrests 3 are screwed onto the surface of the crossbeam 1. The armrests 3 are distributed in an equidistant array from one end of the crossbeam 1 to the other end. A support seat is screwed onto the top of the surface of the crossbeam 1 between two armrests 3. A seat 4 is screwed onto the top of the support seat. A backrest 5 is integrally formed at the top edge of the seat 4.

[0031] To facilitate the rapid installation of handrail 3 and crossbeam 1 in the above example, the following solution is proposed: Figures 3 to 5 As shown, it also includes: a connector 6, a rhombus-shaped mounting base 7, a pivot 8, a mounting component 9, and a limiting component 10. The rhombus-shaped mounting base 7 is connected to the handrail 3 via the connector 6. The connector 6 is designed as a letter hinge, with one part of the connector 6 fixedly connected to the handrail 3 and the remaining part connected to the rhombus-shaped mounting base 7. The inner walls of both the rhombus-shaped mounting base 7 and the handrail 3 are in contact with the surface of the crossbeam 1, and rubber pads are provided at the contact points between the rhombus-shaped mounting base 7 and the handrail 3 and the crossbeam 1. The handrail 3 is fitted onto the pivot 8, and the limiting component 10 is connected to the mounting component 9 via the pivot 8. For the handrail 3 and the diamond-shaped mounting base 7, the mounting part 9 is set as a screw at the bottom and the limiting part 10 is set as a nut. The mounting part 9 and the limiting part 10 are connected by threads. The diamond-shaped mounting base 7 has a limiting groove with a diameter larger than that of the limiting part 10 at the position corresponding to the limiting part 10. When the limiting part 10 moves up to the limiting groove, the rotating shaft 8 cannot rotate. The limiting part 10 is provided with a handle 11, which is located below the limiting part 10 and is used to drive the limiting part 10 to rotate. The rotating shaft 8 is in contact with the inner wall of the handrail 3.

[0032] By changing the connection method between the crossbeam 1, the armrest 3, and the diamond-shaped mounting base 7, the process of disassembling or installing the armrest 3 and the diamond-shaped mounting base 7 with the crossbeam 1 is simplified, which facilitates the maintenance or replacement of the armrest 3 or the diamond-shaped mounting base 7 in the future, thereby shortening the maintenance work of the waiting chair.

[0033] In use, the operator first rotates the shaft 8, which drives the mounting component 9, the limiting component 10, and the handle 11 to rotate synchronously. Then, the operator installs the handrail 3 and the diamond-shaped mounting base 7 onto the surface of the crossbeam 1. By rotating the handrail 3 or the diamond-shaped mounting base 7 around the connector 6, the inner walls of the handrail 3 and the diamond-shaped mounting base 7 are brought into contact with the surface of the crossbeam 1. Next, the operator rotates the shaft 8 in the opposite direction, which drives the mounting component 9, the limiting component 10, and the handle 11 to rotate synchronously in the opposite direction. Rotation stops when the mounting component 9, the limiting component 10, and the handle 11 are perpendicular to the bottom of the handrail 3. Finally, the operator rotates the handle 11, which drives the limiting component 10 to rotate synchronously. The positioning component 10 surrounds the mounting component 9 and moves upward along the threaded groove on the surface of the mounting component 9. When the handle 11 drives the positioning component 10 to move upward to the limiting groove and stops moving upward, the limiting component 10 and the limiting groove restrict the mounting component 9, so that the rotating shaft 8 cannot drive the mounting component 9 to rotate. This completes the process of installing the armrest 3 and the diamond mounting seat 7 on the surface of the crossbeam 1. By changing the connection method between the crossbeam 1 and the armrest 3 and the diamond mounting seat 7, the process of disassembling or installing the armrest 3 and the diamond mounting seat 7 and the crossbeam 1 is simplified, which facilitates the maintenance or replacement of the armrest 3 or the diamond mounting seat 7 in the future, thereby shortening the maintenance work of the waiting chair.

[0034] Specifically, a diamond-shaped mounting base 7 is provided below the handrail 3. A connector 6 is fixedly connected to one side corner of the handrail 3 and the diamond-shaped mounting base 7. The handrail 3 is hinged to the diamond-shaped mounting base 7 through the connector 6. A rotating shaft 8 is rotatably connected inside the handrail 3. A mounting component 9 is fixedly connected inside the rotating shaft 8. A limit component 10 is threadedly connected to the bottom end of the mounting component 9. A handle 11 is fixedly connected to the bottom end of the limit component 10.

[0035] Working principle: When a user needs to sit on the waiting chair, they first sit on the surface of the seat 4. The pressure from the user is transmitted through the seat 4 to the crossbeam 1 via the support seat. Then, the crossbeam 1 transmits the pressure from the user to the ground via the footrests 2 on both sides. The foot pads reduce the vibration generated when the user sits. The user then leans their back against the backrest 5, making the waiting chair more comfortable. At this time, the friction between the grooves on the surface of the seat 4 and the backrest 5 and the user's buttocks and back makes the waiting chair more stable, preventing slippage during long-term use. The counterclockwise tilt of the backrest 5 and seat 4 reduces the pressure on the user's legs during long-term use. The grooves on the surface of the seat 4 and the backrest 5 increase the friction between the user's buttocks and back and the seat 4 and backrest 5, thus preventing numbness, swelling, and other discomfort in the legs during long-term use, thereby improving the user's comfort when sitting on the waiting chair.

[0036] In use, the operator first rotates the shaft 8, which drives the mounting component 9, the limiting component 10, and the handle 11 to rotate synchronously. Then, the operator installs the handrail 3 and the diamond-shaped mounting base 7 onto the surface of the crossbeam 1. By rotating the handrail 3 or the diamond-shaped mounting base 7 around the connector 6, the inner walls of the handrail 3 and the diamond-shaped mounting base 7 are brought into contact with the surface of the crossbeam 1. Next, the operator rotates the shaft 8 in the opposite direction, which drives the mounting component 9, the limiting component 10, and the handle 11 to rotate synchronously in the opposite direction. Rotation stops when the mounting component 9, the limiting component 10, and the handle 11 are perpendicular to the bottom of the handrail 3. Finally, the operator rotates the handle 11, which drives the limiting component 10 to rotate synchronously. The positioning component 10 surrounds the mounting component 9 and moves upward along the threaded groove on the surface of the mounting component 9. When the handle 11 drives the positioning component 10 to move upward to the limiting groove and stops moving upward, the limiting component 10 and the limiting groove restrict the mounting component 9, so that the rotating shaft 8 cannot drive the mounting component 9 to rotate. This completes the process of installing the armrest 3 and the diamond mounting seat 7 on the surface of the crossbeam 1. By changing the connection method between the crossbeam 1 and the armrest 3 and the diamond mounting seat 7, the process of disassembling or installing the armrest 3 and the diamond mounting seat 7 and the crossbeam 1 is simplified, which facilitates the maintenance or replacement of the armrest 3 or the diamond mounting seat 7 in the future, thereby shortening the maintenance work of the waiting chair.
