Description

Technical Field

[0001] The utility model relates to the technical field of sofas, in particular to a sofa armrest. Background Art

[0002] Currently, sofas, driven by the demand for comfort, typically feature upholstered sections, resulting in larger sizes. This occupies a significant volume during storage and transportation, increasing costs. Existing sofas feature removable armrests attached to the main body. During packaging and transportation, the main body and armrests are packaged separately, but the armrests remain a single unit. Consequently, the entire armrest needs to be packaged during transportation, resulting in larger packaging volumes and higher transportation costs.

[0003] In the prior art, for example, U.S. patent application publication number US9867469B2 provides a "Seating device with collapsible arms", in which armrests can be rotated and folded relative to the sides of the seat. The folded armrests can save a certain amount of space, but the folded armrests and the sofa still form a large integral body, which results in a large packaging volume during transportation, which is not conducive to warehousing and transportation.

[0004] Therefore we propose a novel sofa armrest folding mechanism to solve the above-mentioned technical problems. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] References herein to "embodiments" or "implementations" mean that a particular feature, structure, or characteristic described in connection with the embodiments or implementations may be included in at least one embodiment of the present application. The appearance of such phrases in various places in the specification does not necessarily refer to the same embodiment, nor do they constitute independent or alternative embodiments that are mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0030] In this specification, for convenience, words and phrases indicating orientation or positional relationships, such as "middle," "upper," "lower," "front," "back," "vertical," "horizontal," "top," "bottom," "inside," and "outside," are used to illustrate the positional relationships of constituent elements with reference to the accompanying drawings. This is merely for the purpose of facilitating the description of this specification and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present disclosure. The positional relationships of constituent elements may be appropriately changed depending on the orientation of the constituent elements being described. Therefore, the present disclosure is not limited to the words and phrases described in the specification and may be appropriately replaced depending on the circumstances.

[0031] like Figures 1 to 4 As shown, a sofa armrest folding mechanism includes a fixed plate 100 and a rotating plate 200, wherein the fixed plate 100 and the rotating plate 200 are rotatably connected with a connecting member 300; Figure 3 As shown, the connecting member 300 includes an extension portion 301, and the extension portion 301 is provided with a first rotating portion 302 and a second rotating portion 303 along both sides of the longitudinal direction. The first rotating portion 302 and the second rotating portion 303 can respectively rotate around the extension portion 301; a buffer mechanism 400 is also provided between the fixed plate 100 and the rotating plate 200 to alleviate the impact when the fixed plate 100 and the rotating plate 200 are in contact.

[0032] The rotation angle between the extension portion 301 and the first rotation portion 302 is limited to 90 degrees, and the angle between the extension portion 301 and the second rotation portion 303 is limited within a reasonable range, thereby preventing the rotation angle of the rotating plate 200 from being too large.

[0033] The extended portion 301 creates a certain gap between the fixed plate 100 and the rotating plate 200, widens the width of the bottom of the armrest, makes the armrest more beautiful as a whole, and separates the fixed plate 100 and the rotating plate 200 by a certain distance, making it convenient to place the buffer mechanism 400 between the two.

[0034] In this embodiment, the connecting member 300 includes an extension portion 301, a first rotating portion 302, and a second rotating portion 303. This structure enables the fixed plate 100 and the rotating plate 200 to rotate relative to each other, and allows a certain gap to exist between them.

[0035] In other embodiments, other types of connection mechanisms may be considered, such as hinges, slides or other rotating connections, as long as they can achieve the same function, that is, allowing relative rotation between the fixed plate 100 and the rotating plate 200 and providing the necessary gap to accommodate the buffer mechanism 400.

[0036] In this embodiment, the buffer mechanism 400 is placed in the gap between the fixed plate 100 and the rotating plate 200 to alleviate the impact when the two are attached.

[0037] In other embodiments, other types of cushioning materials or mechanisms may be used, such as springs, rubber pads, air bags or other elastic elements, as long as they can provide sufficient cushioning effect to reduce the impact of the fixed plate 100 and the rotating plate 200 when they are fitted together.

[0038] like Figures 1 to 2 As shown, the fixed plate 100 and the rotating plate 200 are rotated through the connecting piece 300 and have an unfolded state and a folded state. When in the unfolded state, the rotating plate 200 is away from the fixed plate 100, and can support the armrest filling material to make it a complete sofa armrest; when in the folded state, the armrest filling material is removed and the rotating plate 200 is close to the fixed plate 100 to reduce the space occupied by the armrest.

[0039] The armrest filling material is used to provide comfort and support when the sofa armrest is in the unfolded state. The specific type of filling material that can be used may include foam, sponge, fabric, etc.

[0040] like Figure 4 As shown, the first rotating part 302 is detachably connected to one side of the fixed plate 100, and the second rotating part 303 is detachably connected to one side of the rotating plate 200. The fixed plate 100 and the rotating plate 200 can rotate as the first rotating part 302 and the second rotating part 303 rotate.

[0041] Detachable connection methods may include screws, buckles, latches, etc., which can also maintain the stability and detachability of the connection.

[0042] like Figure 4As shown, the buffer mechanism 400 includes an elastic block 401 arranged on the fixed plate 100. The elastic block 401 is elastic and can absorb the impact force generated when the rotating plate 200 is in contact, thereby protecting the armrest folding mechanism. The buffer mechanism 400 also includes a pad 402 arranged on the rotating plate 200, and the pad 402 corresponds to the position of the elastic block 401. When the rotating plate 200 is in contact, the pad 402 and the elastic block 401 are in contact, which is used to further ensure the effective absorption of impact force.

[0043] In other embodiments, the specific shape, size, and material of the cushion block 402 may also vary, but the key is that it must be able to cooperate with the elastic block 401 to absorb the impact force. Therefore, the cushion block 402 can be replaced with other types of materials (such as rubber, plastic, etc.) or structures (such as protrusions, grooves, etc.). These materials can form good contact with the elastic block 401 and provide additional cushioning effect.

[0044] like Figures 1 to 2 As shown, a fixing belt 500 is connected to the upper end of the rotating plate 200, and the other end of the fixing belt 500 is connected to the upper end of the fixed plate 100. The fixing belt 500 is an elastic belt. The fixing belt 500 can limit the distance between the rotating plate 200 and the fixed plate 100, thereby preventing the distance between the rotating plate 200 and the fixed plate 100 from exceeding a reasonable range.

[0045] In other embodiments, the specific form (e.g., material, width, length, etc.) of the fixing strap 500 may be different. Therefore, other types of elastic materials (e.g., rubber bands, spring bands, nylon bands, etc.) may be used to replace the fixing strap 500. These materials can also provide similar restraining functions as the fixing strap 500.

[0046] like Figure 2 As shown, a hand grip 201 is provided on the upper end of the rotating plate 200 for easy grasping. The hand grip 201 facilitates grasping the rotating plate 200 , and facilitates the user to grasp and rotate the rotating plate 200 , thereby changing it from a folded state to an unfolded state.

[0047] like Figure 5 As shown, the fixing plate 100 is detachably connected to one longitudinal side of the sofa. When in the unfolded state, the fixing plate 100 and the rotating plate 200 can serve as supports for the armrest filling material. When in the folded state, the fixing plate 100 can be removed, and the sofa armrest is separated from the sofa body. At the same time, the space occupied by the armrest is reduced, making storage and transportation convenient.

[0048] In other embodiments, the specific shape, material, and position of the grip portion 201 may vary, but the key is that it needs to provide a surface that is easy to grasp and apply force. Therefore, other types of structures (such as protrusions, grooves, handles, etc.) can be used to replace the grip portion 201, as long as they can provide similar functions that facilitate grasping.

[0049] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
