Description

Technical Field

[0001] This utility model relates to the field of grandstand seating technology, and in particular to a grandstand seat with a flip-up structure. Background Technology

[0002] Grandstand seating is a dedicated seating facility for audience areas in stadiums, theaters, auditoriums, and other similar venues. It primarily serves to support spectators and provide basic viewing support. It is typically made of materials such as aluminum alloy, polyethylene, or steel, and is characterized by its lightweight, durability, and ease of installation.

[0003] To save space, some grandstands use foldable seats. However, the seats of these foldable grandstand seats often lack a restraining structure, causing them to automatically fold back down under gravity after being folded upwards. This means that the seats need to be folded back down every time someone passes by, which is quite inconvenient. Therefore, how to effectively prevent the folded seats from automatically unfolding is an important problem that needs to be solved in the design of grandstand seats with foldable structures. Utility Model Content

[0004] This invention addresses the problem that upward-flipping seats automatically flip downwards under gravity, providing a grandstand seat with a flip-up structure.

[0005] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0006] This utility model provides a grandstand seat with a flip-up structure, including a seat back and a support frame fixedly connected to the side wall of the seat back.

[0007] A seat structure, wherein the seat structure is disposed on one side of the seat back;

[0008] A support structure is provided at the bottom of the seat structure, and the support structure assists the seat structure in providing stable support.

[0009] A retaining structure is provided on both sides of the seat back.

[0010] Preferably, two support legs are fixedly connected to the bottom side wall of the support frame one, and a support rod two is fixedly connected between the two support legs. The support frame one is fixedly connected to the bottom side wall of the support rod two.

[0011] In this technical solution, the support feet support the seat back.

[0012] Preferably, the sidewall of the support frame one is inclined outward.

[0013] In this technical solution, the second support frame supports the unfolded first support rod.

[0014] Preferably, two sliding grooves are provided on the side walls on both sides of the seat back.

[0015] Preferably, the clamping structure includes a clamping pad and a sliding connecting rod. The sliding connecting rod is slidably connected in two sliding grooves. The clamping pad is fixedly connected to the side wall of the sliding connecting rod. The side walls of the clamping pad are arranged in an arc shape.

[0016] In this technical solution, pushing the sliding connecting rod upward causes it to slide out of the sliding groove, thus completing the disassembly of the abutment pad and facilitating its replacement.

[0017] Preferably, the seat structure includes a fixing block, a seat, a baffle, a sliding guide rail, and a limiting block. The fixing block is fixedly connected to the side wall of the seat back, and the seat is rotatably connected between the fixing blocks. Two baffles are fixedly connected to the side walls on both sides of the seat. Two sliding guide rails are fixedly connected to the bottom side wall of the seat. Limiting blocks are fixedly connected to the side walls at both ends of the two sliding guide rails.

[0018] In this technical solution, the seat is pushed to rotate upward, which in turn drives two baffles to rotate upward. When the two baffles pass the abutment pads on both sides of the seat back, they will squeeze the abutment pads on both sides, increasing the frictional resistance between the baffles and the abutment pads. With the help of the frictional resistance between the baffles and the abutment pads, the seat is prevented from rotating downward under the action of gravity, thus preventing the folded seat from automatically unfolding.

[0019] Preferably, the sidewall of the upper half of the baffle is configured as an arc-shaped structure.

[0020] Preferably, the support structure includes a second fixed block, a first support rod, a third fixed block, a sliding block, and a roller. The second fixed block is fixedly connected to the side wall of the first support rod. One end of the first support rod is rotatably connected to each pair of the second fixed blocks. The other end of the first support rod is rotatably connected to the third fixed block. The sliding block is fixedly connected to the side wall of the third fixed block, and a roller is rotatably connected to the side wall of the sliding block.

[0021] In this technical solution, the support rod 1 unfolds and supports the bottom of the seat board. The seat board, the support rod 1, and the support frame 1 are combined to form a triangle. The triangle has good stability, which allows the support rod 1 to stably support the seat board, thereby giving the seat board a good load-bearing support function. The easily unfolded grandstand seats can be used to comfortably seat people.

[0022] Preferably, the sliding block is slidably connected within the sliding guide rail.

[0023] Preferably, the sidewall of the roller is attached to the inner sidewall of the sliding guide rail.

[0024] In this technical solution, the roller assists the sliding block to slide, making the sliding block slide more smoothly within the sliding guide rail.

[0025] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0026] The positive and progressive effects of this utility model are as follows:

[0027] 1. When the seat is folded, the two baffles will press against the abutment pads on both sides of the seat back when they pass by the abutment pads on both sides. The frictional resistance between the baffles and the abutment pads will increase. With the help of the frictional resistance between the baffles and the abutment pads, the seat will be prevented from rotating downward under the action of gravity, which will help to prevent the seat from automatically unfolding after folding.

[0028] 2. By pushing the seat down until it rotates 90 degrees and is perpendicular to the seat back, support rod one unfolds and supports the bottom of the seat. Support frame two supports support rod one, so that the support seat, support rod one and support frame one are combined to form a stable triangle, so that support rod one stably supports the seat, which makes the seat have a good load-bearing support function and the unfolded grandstand seat can be used to sit down well.

[0029] 3. By pushing the sliding connecting rod upward, the sliding connecting rod slides out of the sliding groove, completing the disassembly of the abutment pad, making it easy to replace the abutment pad. Attached Figure Description

[0036] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0037] like Figure 1-4 As shown, a grandstand seat with a flip-up structure includes a seat back 1 and a support frame 2 fixedly connected to the side wall of the seat back 1.

[0038] Seat structure 5, wherein the seat structure 5 is disposed on one side of the seat back 1;

[0039] Support structure 7 is provided at the bottom of seat structure 5, and the support structure 7 assists seat structure 5 in providing stable support;

[0040] A retaining structure 9 is provided on both sides of the seat back 1.

[0041] Two support legs 3 are fixedly connected to the bottom side wall of the support frame 2, and a support rod 8 is fixedly connected between the two support legs 3. The support frame 2 is fixedly connected to the bottom side wall of the support rod 8.

[0042] Support leg 3 supports seat back 1.

[0043] The sidewalls of the support frame 2 are inclined outwards.

[0044] Support frame 26 supports the unfolded support rod 1 702.

[0045] Two sliding grooves 4 are provided on the side walls on both sides of the seat back 1.

[0046] The clamping structure 9 includes a clamping pad 901 and a sliding connecting rod 902. The sliding connecting rod 902 is slidably connected in two sliding grooves 4. The clamping pad 901 is fixedly connected to the side wall of the sliding connecting rod 902. The side walls on both sides of the clamping pad 901 are arranged in an arc shape.

[0047] Push the sliding connecting rod 902 upwards so that it slides out of the sliding groove 4, completing the disassembly of the clamping pad 901 and facilitating its replacement.

[0048] The seat structure 5 includes a fixing block 501, a seat 502, a baffle 503, a sliding guide rail 504, and a limiting block 505. The fixing block 501 is fixedly connected to the side wall of the seat back 1. The seat 502 is rotatably connected between the fixing blocks 501. Two baffles 503 are fixedly connected to the side walls on both sides of the seat 502. Two sliding guide rails 504 are fixedly connected to the bottom side wall of the seat 502. The limiting blocks 505 are fixedly connected to the side walls at both ends of the two sliding guide rails 504.

[0049] Pushing the seat 502 upwards causes the two baffles 503 to rotate upwards. When the two baffles 503 pass the abutment pads 901 on both sides of the seat back 1, they will squeeze the abutment pads 901 on both sides, increasing the frictional resistance between the baffles 503 and the abutment pads 901. With the help of the frictional resistance between the baffles 503 and the abutment pads 901, the seat 502 is prevented from rotating downwards under the action of gravity, thus preventing the folded seat from automatically unfolding.

[0050] The upper half of the baffle 503 has a side wall with an arc-shaped structure.

[0051] The support structure 7 includes a second fixed block 701, a first support rod 702, a third fixed block 703, a sliding block 704, and a roller 705. The second fixed block 701 is fixedly connected to the side wall of the first support rod 702. One end of the first support rod 702 is rotatably connected between each pair of the second fixed blocks 701. The other end of the first support rod 702 is rotatably connected to the third fixed block 703. The sliding block 704 is fixedly connected to the side wall of the third fixed block 703. The roller 705 is rotatably connected to the side wall of the sliding block 704.

[0052] The support rod 702 unfolds and supports the bottom of the seat 502. The seat 502, the support rod 702, and the support frame 2 are combined to form a triangle. The triangle has good stability, which allows the support rod 702 to stably support the seat 502. This gives the seat 502 a good load-bearing support function, and the easily unfolded grandstand seats can be used to comfortably seat people.

[0053] The sliding block 704 is slidably connected within the sliding guide rail 504.

[0054] The sidewall of the roller 705 is attached to the inner sidewall of the sliding guide rail 504.

[0055] The roller 705 assists the sliding block 704 in sliding, making the sliding block 704 slide more smoothly within the sliding guide rail 504.

[0056] When this utility model is in use, during the flipping and folding process, the seat plate 502 is pushed to rotate upwards. The seat plate 502 drives the two baffles 503 and the sliding guide rail 504 to rotate upwards. The sliding block 704 slides downwards within the sliding guide rail 504. The support rod 702 rotates upwards along with the seat plate 502 and rotates synchronously toward the seat back 1 until the seat plate 502 is pressed against the side wall of the seat back 1. The support rod 702 is pressed against the side wall of the seat plate 502 and folded up. When the two baffles 503 pass the abutment pads 901 on both sides of the seat back 1, they will squeeze the abutment pads 901 on both sides. The frictional resistance between the baffles 503 and the abutment pads 901 increases. With the help of the frictional resistance between the baffles 503 and the abutment pads 901, the seat plate 502 is prevented from rotating downwards under the action of gravity, thus preventing the folded seat from automatically unfolding.

[0057] When unfolded for use, the seat 502 is pushed downwards, causing the sliding guide rail 504 to rotate downwards. The sliding guide rail 504 pushes the support rod 702 downwards, and the sliding block 704 slides within the sliding guide rail 504. The roller 705 assists the sliding block 704 in sliding, making the sliding block 704 slide more smoothly within the sliding guide rail 504 until the seat 502 rotates 90 degrees and is perpendicular to the seat back 1. The support rod 702 then unfolds and supports the bottom of the seat 502. The support frame 6 supports the support rod 702, preventing it from moving further downwards. The seat 502, the support rod 702, and the support frame 6 combine to form a triangle. The triangle has good stability, allowing the support rod 702 to stably support the seat 502, thus giving the seat 502 good load-bearing support. The easily unfolded grandstand seat can be comfortably seated.

[0058] When the clamping pad 901 becomes aged or damaged, push the sliding connecting rod 902 upward to make the sliding connecting rod 902 slide out of the sliding groove 4, thus completing the disassembly of the clamping pad 901 and facilitating its replacement.
