Rotatable cushion

Abstract

The present invention relates to the technical field of furniture and provides a rotatable cushion. The device has a circular body, including an upper cover 1, a base 2, and a ball plate 6 between the upper cover and the base. The surface of the upper cover is fitted with a multi-size pad 3, and the bottom of the base is coated with an anti-slip coating 4. A cylindrical rotating shaft 5 is provided between the upper cover and the base, penetrating the ball plate, with both ends removably connected to the inner walls of the upper cover and the base, respectively. The ball plate is uniformly provided with a plurality of recesses 7, each of which is fitted with a ball 8, the diameter of which is the same as the distance between the inner walls of the upper cover and the base. The balls within the rotatable cushion provide sufficient strength, evenly support the upper cover, and allow movement with the twisting of the body, preventing the entire cushion from sliding, resulting in high comfort, safety, and adaptability.

Description

[Technical Field]

[0001] The present invention relates to the technical field of household products, and more particularly to a rotatable cushion. [Background technology]

[0002] Cushions are common household items, characterized by their lightweight, soft, and portable fabric. They can be used in a variety of places, such as chairs, sofas, bay windows, and cars, providing protection and comfort. Cushions are typically made of a thin, multi-layered sheet primarily made of a single layer of sponge. While cushions provide a certain level of support to the human body when seated, they cannot maintain a forward-facing posture while sitting on a cushion. Furthermore, when a person twists their body, the pressure on the cushion is not uniform. Therefore, the frictional force of the cushion is small, and the entire cushion slides when the person twists their body, reducing the user experience and potentially posing a safety risk. Summary of the Invention [Problem to be solved by the invention]

[0003] In response to the problem of sliding that occurs when a person twists their body with conventional cushions, the present invention provides a rotatable cushion. The rotatable cushion is circular, and the main body includes an upper cover, a base, and a ball plate installed between the upper cover and the base. The upper cover has a padded surface and a non-slip coating on the bottom of the base. A cylindrical rotation shaft is installed between the upper cover and the base, and passes through the ball plate. Both ends of the rotation shaft are removably connected to the inner walls of the upper cover and the base, respectively. The ball plate is uniformly provided with a plurality of recesses that pass through it, and a ball is fitted into each recess, with the diameter of the ball being the same as the distance between the upper cover and the inner wall of the base.

[0004] Specifically, the upper cover base and the rotary shaft are engaged and connected, which provides a tight connection and allows for convenient detachment at any time, facilitating repair and replacement of internal components.

[0005] In addition, the upper cover and the surface of the anti-slip coating layer are provided with anti-slip granules, which can further increase the friction force and prevent displacement.

[0006] Furthermore, the recesses are uniformly distributed in a concentric manner to prevent the upper cover from being deformed or torn apart after prolonged use.

[0007] The recessed groove is a spindle-shaped cylinder with a wide center and narrow ends, and the diameter of the openings at both ends is slightly smaller than the diameter of the ball. This design prevents the ball from falling out and makes it easy to replace the ball.

[0008] The balls installed inside the swivel cushion of this invention provide sufficient strength to the cushion and evenly support the upper cover, allowing it to move with the twisting of the human body without the entire cushion sliding, resulting in high comfort, safety, and adaptability. Furthermore, the surface of the upper cover of this invention can be adapted to various specifications of pads depending on the usage scenario, making it highly versatile.

DETAILED DESCRIPTION OF THE INVENTION

[0010] The present invention will be described below with reference to the following examples. The examples are provided to illustrate the present invention and are not intended to limit the scope of the present invention.

[0011] As shown in FIGS. 1 to 3, the rotatable cushion is circular, and the main body includes an upper cover 1, a base 2, and a ball plate 6 disposed between the upper cover 1 and the base 2. A removable pad 3 is fitted to the surface of the upper cover 1, and an anti-slip coating layer 4 is disposed on the bottom surface of the base 2. Anti-slip granules are disposed on the surfaces of the upper cover 1 and the anti-slip coating layer 4, respectively. A cylindrical rotating shaft 5 is disposed between the upper cover 1 and the base 2, and the rotating shaft 5 penetrates the ball plate 6, with both ends of the rotating shaft 5 removably connected to the inner walls of the upper cover 1 and the base 2, respectively. The base 2 is centrally connected, and the ball plate 6 is uniformly provided with a plurality of recessed grooves 7 that penetrate through the ball plate 6, which are uniformly distributed in a concentric manner. The recessed grooves 7 are spindle-shaped, wider in the middle and narrower at both ends, and a ball 8 is inserted into each recessed groove 7. The diameter of the openings at both ends of the embedding groove 7 is slightly smaller than the diameter of the ball 8 , and the diameter of the ball 8 is the same as the distance between the inner wall of the upper cover 1 and the base 2 .

[0012] The above description is only illustrative of the preferred embodiments of the present invention, and does not limit the present invention. Any modifications, equivalent changes, improvements, etc. made within the spirit and principle of the present invention are included within the scope of the utility model registration claims of the present invention.
