Description

Technical Field

[0001] The present invention relates to the technical field of seat structures, and particularly relates to a rotatable table and chair combination that is always located under the shade of a tree. Background Art

[0002] In summer, the shade of a tree is an ideal resting environment for people. In parks and green spaces, rest facilities such as benches are often set under big trees. However, the position of traditional benches is fixed, while the shadow of the tree changes with the direction of sunlight, resulting in the benches and the people sitting on them being exposed to the scorching sun, and it cannot meet people's need to sit under the shade of a tree for a long time. Summary of the Invention

[0003] The purpose of the present invention is to provide a rotatable table and chair combination that is always located under the shade of a tree to meet people's need to sit under the shade of a tree for a long time.

[0004] To achieve the foregoing purpose, the present invention adopts the following technical solutions.

[0005] A rotatable table and chair combination that is always located under the shade of a tree, comprising a tree support, a track, a seat assembly, a driving pulley, and a sensor. The driving pulley includes a motor and a pulley. The tree support is fixedly connected to the ground and surrounds the lower part of the tree trunk. The seat assembly is rotatably connected to the tree support. The pulley is installed at the bottom of the seat assembly and can slide on the track. The sensor is installed on the top of the seat assembly. Both the sensor and the motor are electrically connected to a control terminal.

[0006] For the present invention adopting the foregoing scheme, by fixedly connecting the tree support to the ground and surrounding the lower part of the tree trunk, rotatably connecting the seat assembly to the tree support, and also providing a driving pulley including a motor and a pulley, when the sensor installed on the top of the seat assembly detects sunlight on the seat assembly, it sends a message to the control terminal, and the control terminal issues a start command to the motor. The motor rotates to drive the pulley to rotate synchronously. When the sensor does not send a message, the control terminal issues a stop command to the motor, so that the seat assembly stays under the shade of the tree, preventing the seat and the people sitting on the seat from being exposed to the scorching sun, and meeting people's need to sit under the shade of a tree for a long time.

[0007] Preferably, the track is integrally annular and surrounds the outer periphery of the tree trunk.

[0008] In this way, by making the track integrally annular and surrounding the outer periphery of the tree trunk, it is convenient for the seat assembly to move under the shade formed by the entire tree crown, so that the seat assembly can stay under the shade of the tree for a long time.

[0009] Preferably, the output shaft of the motor is connected to the pulley through a reduction gear pair.

[0010] In this way, by setting up a reduction gear pair to reduce the output torque of the motor and then transmit it to the pulley, the table and chair assembly can slide slowly, improving the positioning accuracy of the seat assembly.

[0011] Preferably, the seat assembly includes a tabletop, several seat connectors, and several seat parts. The seat connectors are evenly distributed on both sides of the tabletop. One end of each seat connector is connected to the tabletop, and the other end is connected to the seat part.

[0012] In this way, by setting up several seat connectors and several seat parts, and evenly distributing the seat connectors on both sides of the tabletop, with one end of each seat connector connected to the tabletop and the other end connected to the seat part, it is convenient to provide enough seats for people to rest.

[0013] Preferably, the seat part can be a stool board or a seat with a backrest.

[0014] In this way, the seat part can be a stool board or a seat with a backrest, providing multiple options for people to use.

[0015] Preferably, the sensor is installed on the top of the tabletop and at one end away from the tree trunk.

[0016] In this way, by installing the sensor on the top of the tabletop and at one end away from the tree trunk, the branches at the end away from the tree trunk are sparser and the possibility of sunlight irradiation is greater, facilitating accurate detection of whether sunlight is irradiating on the seat.

[0017] Preferably, the tabletop can be rectangular or oval.

[0018] Preferably, a battery is installed at the lower end of the tabletop, and the battery is electrically connected to the motor.

[0019] In this way, by installing a battery at the lower end of the tabletop and electrically connecting the battery to the motor, it is convenient to provide kinetic energy for the motor through the battery.

[0020] Preferably, a vertically arranged support plate is connected to the lower end of the tabletop, and the pulley is slidably connected to the lower end of the support plate.

[0021] In this way, by setting up the support plate, it can not only provide support for the seat assembly but also guide the pulley to ensure that the pulley is located within the slide rail.

[0022] Preferably, the tree support is in an overall cylindrical tube structure, and the tabletop is rotatably connected to the tree support through a bearing.

[0023] In this way, by setting the tree support as an overall cylindrical tube structure and making the tabletop rotatably connected to the tree support through a bearing, the friction between the tabletop and the tree support is reduced through the bearing, enabling the tabletop to rotate smoothly.

[0024] The beneficial effects of the present invention are as follows: By fixedly connecting the tree support to the ground and surrounding the lower part of the tree trunk, and rotatably connecting the seat assembly to the tree support, a driving pulley including a motor and a pulley is also provided. When the sensor installed on the top of the seat assembly detects sunlight on the seat assembly, it sends a message to the control terminal, and the control terminal issues a start command to the motor. The motor rotates to drive the pulley to rotate synchronously. When the sensor does not send a message, the control terminal issues a stop command to the motor, so that the seat assembly stays in the shade, preventing the seat and the people sitting on the seat from being irradiated by the scorching sun and meeting the need for people to sit in the shade for a long time. By making the tree support as a whole in a cylindrical tube structure and enabling the tabletop to be rotatably connected to the tree support through a bearing, the friction between the tabletop and the tree support is reduced through the bearing, enabling the tabletop to rotate smoothly.
