[0001] This utility model relates to the field of movie-watching aids technology, specifically to barrier-free movie-watching aids. Background Technology

[0002] A cinema is a venue specifically designed to screen films for audiences. Cinemas must meet the technological requirements for film projection to ensure viewers receive a good visual and auditory experience. With the development of film technology, cinemas have evolved from silent to sound-based, from black-and-white to color films, and then to widescreen and dome screens, constantly upgrading. Cinemas are typically equipped with viewing props, such as seats, which are an indispensable part of the equipment, providing seating for people to watch films and improving their comfort.

[0003] While existing movie theater seats are soft and have a certain degree of elasticity, making it comfortable for people to sit for extended periods, they lack assistive functions. Due to mobility issues and insufficient muscle strength, some people with disabilities face difficulties getting up and sitting down, making the existing movie theater seats unsuitable for them. Furthermore, the existing movie theater seats are not flexible enough and are inconvenient to operate. Utility Model Content

[0004] The purpose of this invention is to provide an accessible movie-watching aid. By activating the motor, the drive shaft rotates the bidirectional lead screw, causing the two nuts to move closer together and drive the rotating component to rotate while pushing the support seat upwards until the support seat and cushion are raised to a suitable position. Then, the person with a disability can place their buttocks on the support seat, and the support seat can be lowered, allowing the person with a disability to sit down slowly as the support seat descends. When they need to get up, they can follow the same principle. This achieves the effect of barrier-free sitting and getting up with this movie-watching aid, improving its assistive function and solving the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides an accessible movie-watching aid, including a seat with an internal cavity and a backrest installed at one end of the seat, and also including...

[0006] The support base is located above the seat and has the same width as the seat.

[0007] A two-way lead screw is installed on the inner wall of the cavity and rotates horizontally, with two nuts symmetrically threaded on it;

[0008] The motor is fixedly installed on the inner wall of the seat, and the end of the bidirectional lead screw away from the inner wall of the seat is connected to the drive shaft of the motor.

[0009] The number of rotating parts corresponds to the number of nuts, and they are symmetrically arranged between the nuts and the support.

[0010] Furthermore, a mounting base is fixedly installed on the top of the nut, and a fixing base is fixedly installed at the center of the bottom of the support base. The two ends of the rotating component are respectively rotatably disposed in the mounting base and the fixing base.

[0011] Furthermore, a first pin is provided in the mounting base, a second pin is provided in the fixed base, and the two ends of the rotating component are respectively rotatably sleeved on the first pin and the second pin.

[0012] Furthermore, the top of the seat has a sliding opening that communicates with the interior of the seat, and the rotating component is slidably connected within the sliding opening.

[0013] Furthermore, a fixed shaft is fixedly installed on the rear side of both nuts, and a rotating rod is rotatably sleeved on the fixed shaft. A connecting rod is fixedly installed at the center of the bottom of the support base, and a limit seat is provided at the bottom of the connecting rod. The end of the rotating rod away from the fixed shaft is rotatably disposed in the limit seat, and the rotating rod is slidably inserted into the sliding port.

[0014] Furthermore, a third pin is provided inside the limiting seat, and the end of the rotating rod away from the fixed shaft is rotatably sleeved on the third pin.

[0015] Furthermore, a damper is fixedly installed on the top of the support base, and a buffer pad is provided at the other end of the damper. Two electric push rods are symmetrically arranged at the bottom of the support base, and the driving end of the electric push rod passes through the support base and abuts against the bottom of the buffer pad.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: by turning on the motor, the drive shaft of the motor can drive the bidirectional lead screw to rotate, so that the two nuts come closer to each other and drive the rotating parts to rotate while pushing the support seat upward until the support seat and the cushioning pad are raised to a suitable position. Then, the disabled person can rest their buttocks on the support seat, and then lower the support seat, so that the disabled person can sit down slowly as the support seat descends. When they need to get up, they can operate according to the above principle. The operation is flexible and realizes the effect of barrier-free sitting and getting up of the movie viewing prop, thus improving the auxiliary effect of the movie viewing prop.

[0018] Compared with the prior art, the beneficial effects of this utility model are: during the lifting and lowering of the support base, the rotating rod will rotate and push and pull the support base, which can relieve the pressure of the person's own weight on the rotating parts, thereby helping to solve the problem of breakage caused by the rotating parts being unable to support the weight, and ensuring the long-term use of the movie viewing prop.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: During the lifting and lowering process of the support seat, the motor will generate a large vibration. At this time, the electric push rod can be activated so that the drive end of the electric push rod is shortened and does not contact the cushion. Subsequently, when the vibration is transmitted to the support seat and the cushion, it can be absorbed by the damper, which plays a buffering role during the lifting and lowering process. This avoids the problem that disabled people are prone to tipping over and falling due to the vibration of the movie viewing prop. It is easy to operate and can further improve the effect of barrier-free sitting up. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 This utility model provides a technical solution: an accessible movie-watching aid, including a seat 1 with an internal cavity and a backrest 2 installed at one top end of the seat 1, and also including...

[0027] Support 3 is located above seat 1 and has the same width as seat 1;

[0028] A two-way lead screw 4 is installed on the inner wall of the cavity in a horizontal direction, and two nuts 5 are symmetrically threaded on it;

[0029] Motor 6 is fixedly installed on the inner wall of seat 1, and the end of the bidirectional lead screw 4 away from the inner wall of seat 1 is connected to the drive shaft of motor 6.

[0030] Rotating component 7, the number of which corresponds to that of nut 5, is symmetrically arranged between nut 5 and support 3;

[0031] A mounting base 8 is fixedly installed on the top of the nut 5, and a fixing base 9 is fixedly installed at the center of the bottom of the support base 3. The two ends of the rotating part 7 are respectively rotatably set in the mounting base 8 and the fixing base 9. A first pin is set in the mounting base 8, and a second pin is set in the fixing base 9. The two ends of the rotating part 7 are respectively rotatably sleeved on the first pin and the second pin. A sliding opening 10 is opened on the top of the seat 1. The sliding opening 10 is connected to the inside of the seat 1, and the rotating part 7 is slidably connected in the sliding opening 10.

[0032] In practice, if a person with disabilities needs to sit on the movie-watching aid, first turn on the motor 6. The drive shaft of the motor 6 will drive the bidirectional lead screw 4 to rotate, causing the two nuts 5 to move closer together and drive the rotating part 7 to rotate while pushing the support seat 3 upward until the support seat 3 and the cushion 16 are raised to a suitable position. Then, the person with disabilities can place their buttocks on the support seat 3 and then lower the support seat 3. This allows the person to sit down slowly as the support seat 3 descends. When they need to get up, they can do so according to the above principle. This achieves the effect of barrier-free sitting and getting up on the movie-watching aid and improves the aid's assistive effect.

[0033] See Figure 1-4 A fixed shaft 11 is fixedly installed on the rear side of each of the two nuts 5. A rotating rod 12 is rotatably sleeved on the fixed shaft 11. A connecting rod 13 is fixedly installed at the center of the bottom of the support base 3. A limit seat 14 is provided at the bottom of the connecting rod 13. The end of the rotating rod 12 away from the fixed shaft 11 is rotatably set in the limit seat 14. The rotating rod 12 is slidably inserted into the slide 10. A third pin is provided in the limit seat 14. The end of the rotating rod 12 away from the fixed shaft 11 is rotatably sleeved on the third pin.

[0034] In practice, based on the above implementation, during the lifting and lowering of the upper support base 3, the rotating rod 12 will rotate and push and pull the support base 3, which can relieve the pressure of the person's own weight on the rotating part 7, thereby helping to solve the problem of the rotating part 7 breaking due to being unable to support the weight, and ensuring the long-term use of the movie viewing prop.

[0035] See Figure 1-4A damper 15 is fixedly installed on the top of the support base 3, and a buffer pad 16 is provided at the other end of the damper 15. Two electric push rods 17 are symmetrically arranged at the bottom of the support base 3. The driving end of the electric push rod 17 passes through the support base 3 and abuts against the bottom of the buffer pad 16. The damper 15 includes a damping cylinder and a spring. The two ends of the damping cylinder and the spring are respectively installed between the support base 3 and the buffer pad 16.

[0036] In specific implementation, based on the above implementation, during the lifting and lowering of the support seat 3, the activation of the motor 6 will generate significant vibration. At this time, the electric push rod 17 can be activated to shorten the drive end of the electric push rod 17, so that the drive end of the electric push rod 17 does not contact the bottom of the cushion 16. Subsequently, when the vibration is transmitted to the support seat 3 and the cushion 16, it can be absorbed by the damper 15, which plays a buffering role during the lifting and lowering process. This avoids the problem of disabled people easily falling to the side due to the vibration of the movie viewing prop, and can further improve the effect of barrier-free sitting up.

[0037] Before use, all electrical appliances involved in the movie-watching aid should be connected to an external power source. The battery pack can be installed inside the seat 1 in a position that does not obstruct the operation of other components. The battery pack and the electrical appliances are electrically connected through a circuit to provide power to the electrical appliances and ensure their normal operation. Since connecting the electrical appliances to an external power source and installing the battery pack are both existing and mature technologies, and are not problems that need to be solved in the background technology of this manual, they will not be elaborated on further.

[0038] In addition, to facilitate the control of the electrical appliances involved in this movie-watching aid prop, a controller can be installed on the side of the cushion 16. The controller is electrically connected to the electrical appliances, and the personnel can operate the controller to control the switching and operation of the electrical appliances. Since the controller is existing technology, it will not be described in detail in this manual.

[0039] Working principle: When in use, if a person needs to sit on this movie-watching aid, first turn on the motor 6, so that the drive shaft of the motor 6 drives the bidirectional lead screw 4 to rotate, so that the two nuts 5 come closer to each other and drive the rotating part 7 to rotate while pushing the support base 3 upward until the support base 3 and the cushion 16 are raised to a suitable position. Then, the person puts their buttocks on the support base 3, and then lowers the support base 3, so that the person can sit down slowly as the support base 3 descends. When it is necessary to get up, just press the above-mentioned movement away operation. This achieves the effect of barrier-free sitting and getting up from the movie-watching aid and improves the auxiliary effect of the movie-watching aid.

[0040] In addition, during the lifting and lowering of the support base 3, the rotating rod 12 will rotate and push and pull the support base 3, which can relieve the pressure of the person's own weight on the rotating part 7, thereby helping to solve the problem of the rotating part 7 breaking due to being unable to support the weight, and ensuring the long-term use of the movie viewing prop.

[0041] It should be noted that during the lifting and lowering of the support seat 3, the activation of the motor 6 will generate significant vibration. At this time, the electric push rod 17 can be activated to shorten the drive end of the electric push rod 17, so that the drive end of the electric push rod 17 does not contact the bottom of the cushion 16. Subsequently, when the vibration is transmitted to the support seat 3 and the cushion 16, it can be absorbed by the damper 15, which plays a buffering role during the lifting and lowering process. This avoids the problem of disabled people easily tipping over and falling off due to the vibration of the movie viewing prop, and can further improve the effect of barrier-free sitting up.
