Abstract
Description
Technical Field
[0001] The utility model relates to the field of seats, in particular to an openable flip mechanism of a chair. Background Art
[0002] A chair is a piece of furniture with a backrest and sometimes armrests. With market competition and social development, the industry is also evolving, and chairs have reached the realm of art. Various artistic chair designs have emerged, such as egg-shaped chairs, red lip-shaped chairs, and various massage chairs.
[0003] Chair massagers on the market lack flip mechanisms, which is uncomfortable. Directly mounted massagers have raised bumps that can be uncomfortable. (Because chairs are meant to be sat on, traditional chairs aren't professional massage chairs, which aren't meant for prolonged sitting.) Secondly, most chairs lack massage technology, like vibration-like massage functions, which don't truly address the lack of comfort associated with mechanical massage. Furthermore, massage chairs are cumbersome and difficult to use. Utility Model Content

DETAILED DESCRIPTION
[0025] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the embodiments of the present invention, and should not be construed as limiting the present invention.
[0026] In the description of the embodiments of the present invention, it should be understood that if there are directional indications in the embodiments of the present invention, such as the orientation or position relationship of up, down, left, right, front, back, inside, and outside, which are based on the orientation or position relationship shown in the accompanying drawings, it is only for the convenience of describing the embodiments of the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, "plurality" means two or more, unless otherwise specifically defined.
[0028] In the embodiments of the present invention, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connected," and "fixed" should be understood broadly. For example, they may refer to fixed connections, removable connections, or integration. They may refer to mechanical connections or electrical connections. They may refer to direct connections or indirect connections through an intermediary. They may refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of these terms in the embodiments of the present invention based on the specific circumstances.
[0029] See also Figures 1 to 5 As shown, an openable flip mechanism of a chair includes a seat 1, a flip layer 2 and an adjustment plate 3 arranged on a support. The bottom of the flip layer 2 is in contact with the seat 1 and is rotatably connected to the seat 1 through a first positioning pin 20. The left and right sides of the adjustment plate 3 are rotatably connected to the flip layer 2 through a second positioning pin 30. The front and back surfaces thereof respectively include a massage surface 31 and a seat back surface 32. The flip layer 2 rotates on the seat 1 around the pin connection of the first positioning pin 20 to drive the adjustment plate 3 to leave the seat 1. The adjustment plate 3 flips and rotates on the flip layer 2 around the pin connection of the second positioning pin 30 to flip the adjustment plate 3 so that the massage surface 31 and the seat back surface 32 are switched.
[0030] When in use, the flip layer 2 can be directly pulled to make the adjustment plate 3 leave the side wall of the seat 1, and the distance between the two is sufficient for the adjustment plate 3 to rotate around the pin joint of the second positioning pin 30, so that the adjustment plate 3 can rotate the massage surface 31 and the seat back surface 32 out, so that the user can flip and switch the chair, so that the chair with this structure can be used in both normal sitting and massage states.
[0031] It can be understood that by rotating the flip layer 2 directly to a position where it fits in with the bottom of the seat 1 , the massage surface 31 can be directed toward the legs of the human body, so that the structure can massage the legs of the human body.
[0032] In some embodiments, the seat 1, the flip layer 2 and the adjustment plate 3 are all wrapped with a soft outer covering 100. The outer wall of the seat 1 and the outer wall of the flip layer 2 are in contact with each other through the corresponding soft outer covering 100. The soft outer covering 100 can not only enhance the comfort of the structure, but also provide sufficient friction on both sides of the flip layer 2 to prevent the flip layer 2 from automatically flipping due to gravity or vibration.
[0033] In some embodiments, the seat 1 includes a backrest 10, a seat cushion 11 is provided at the bottom of the backrest 10, the flip layer 2 is pinned to the bottom of the backrest 10 through the first positioning pin 20, and armrests 12 are provided on both sides of the seat cushion 11. The seat cushion 11 and the armrests 12 are an integrated structure, and the armrests 12 that are an integrated structure with the seat cushion 11 can further increase the comfort of use of the structure.
[0034] Furthermore, a bracket 13 is provided at the bottom of the seat cushion 11, and a plurality of universal wheels 14 are provided at the bottom of the bracket 13. In this embodiment, the bracket 13 with universal wheels 14 is used to support the seat 1 to further increase the flexibility of the seat 1. In addition to this solution, it can also be designed as a sofa placed directly on the ground, a hanging chair suspended on a beam, and so on.
[0035] In some embodiments, a reinforcement plate 33 is provided at the adjustment plate 3 corresponding to the second positioning pin 30, and the end of the second positioning pin 30 is inserted into the reinforcement plate 33. Since the adjustment plate 3 is pinned via the second positioning pin 30, when the adjustment plate 3 rotates, the second positioning pin 30 will inevitably have a certain amount of wear, so providing a reinforcement plate 33 at its assembly location can effectively increase the service life of the structure.
[0036] In some embodiments, a massage terminal 310 is provided on the adjustment plate 3 corresponding to the massage surface 31 , a circuit harness 300 is provided in the second positioning pin 30 , and the massage terminal 310 is connected to the power supply through the circuit harness 300 .
[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
