Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of sofas and in particular to a sofa armrest. STATE OF THE ART

[0002] Due to the high demands for comfort, sofas currently generally have upholstered parts, resulting in a very large sofa size, which results in the product occupying a very large volume during storage and transportation, increasing costs. Existing sofas are designed with the armrests of the sofa detachably arranged on the main body of the sofa. During packaging and transportation, the main body of the sofa and the armrests of the sofa are packaged separately, but the armrests of the sofa are still an integral structure. Therefore, the entire armrest must be packaged during transportation, resulting in larger packaging volume and higher transportation costs.

[0003] In the prior art, US patent application publication number US9867469B2 proposes a "seating device with collapsible arms" whose armrests can be rotated relative to the side of the seat and folded.

[0017] The technical solutions in the embodiments of the utility model are described clearly and completely below in conjunction with the accompanying drawings. It is understood that the described embodiments represent only a portion of the embodiments of the utility model and not all embodiments. Starting from the embodiments in this application, all other embodiments that a person skilled in the art can obtain without creative effort fall within the scope of this application.

[0018] Reference to "embodiments" or "modes of embodiment" means that certain features, structures, or characteristics described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this term in various places in the specification does not necessarily all refer to the same embodiment, nor does it represent a separate or alternative embodiment that excludes other embodiments. It will be understood by those skilled in the art, both explicitly and implicitly, that the embodiments described herein may be combined with other embodiments.

[0019] In the description, it should be understood that the terms "top", "bottom", "front", "back", "left", "right", "vertical", "horizontal", "upper", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings and are used only to simplify the description of the utility model and simplify the description, rather than indicating or implying what is referred to. The device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. The positional relationships of individual elements change according to the orientation of the described elements. It is therefore not limited to the words and phrases shown in the description, which can be replaced depending on the circumstances.

[0020] As in the Fig. 1 to 4, the sofa armrest folding mechanism comprises a fixed plate 100 and a rotating plate 200, the fixed plate 100 and the rotating plate 200 being rotatably connected to each other by a connecting element 300; wherein, as Fig. 3, the connecting element 300 comprises an extension part 301, wherein the extension part 301 is provided with a first rotating portion 302 and a second rotating portion 303, each rotating along both sides of the longitudinal direction; wherein the first rotating portion 302 and the second rotating portion 303 can each perform a rotating movement about the extension part 301; wherein a damping mechanism 400 is further provided between the fixed plate 100 and the rotating plate 200 in order to dampen the impact when the fixed plate 100 abuts against the rotating plate 200.

[0021] The angle of rotation between the extension part 301 and the first rotating portion 302 is limited to 90 degrees, and the angle between the extension part 301 and the second rotating portion 303 is limited to a reasonable range to avoid an excessive angle of rotation of the rotating plate 200.

[0022] The extension part 301 creates a certain distance between the fixed plate 100 and the rotating plate 200, increases the width of the bottom of the armrest, makes the armrest as a whole more aesthetically pleasing, and ensures that the fixed plate 100 and the rotating plate 200 are separated by a certain distance, which facilitates the placement of the damping mechanism 400 between them.

[0023] In this embodiment, the connecting member 300 includes a connecting member 301, a first rotating portion 302, and a second rotating portion 303. This structure allows the fixed plate 100 and the rotating plate 200 to rotate relative to each other and allows a clearance between them.

[0024] In other embodiments, other types of connection mechanisms may be considered, such as hinges, slide rails, or other pivot connections, as long as they can perform the same function, that is, to allow relative rotation between the fixed plate 100 and the pivot plate 200 and to provide the necessary clearance to accommodate the damping mechanism 400.

[0025] In this embodiment, the damping mechanism 400 is placed in the space between the fixed plate 100 and the rotating plate 200 to dampen impact when the fixed plate abuts the rotating plate.

[0026] In other embodiments, other types of damping materials or mechanisms such as springs, rubber cushions, airbags, or other resilient elements may be used as long as they provide sufficient damping to absorb impacts when the fixed plate 100 abuts the rotating plate 200.

[0027] As in the Fig. As shown in Figures 1 to 2, the fixed plate 100 and the rotating plate 200 are rotated by the connecting member 300 and have an unfolded state and a folded state. When in the unfolded state, the rotating plate 200 is far away from the fixed plate 100, and at this time, the armrest cushioning material can be supported, thus becoming a complete sofa armrest; when in the folded state, the armrest cushioning material is removed, and the rotating plate 200 rotates close to the rotating plate 100, reducing the space occupied by the armrest.

[0028] The armrest cushioning material is designed to provide comfort and support when the sofa armrests are in the unfolded state, and certain types of cushioning materials such as foam, sponge, fabric, etc. can be used.

[0029] As in Fig. As shown in Figure 4, the first rotating portion 302 is detachably connected to the side of the fixed plate 100, and the second rotating portion 303 is detachably connected to the side of the rotating plate 200. The fixed plate 100 and the rotating plate 200 can rotate with the rotation of the first rotating portion 302 and the second rotating portion 303.

[0030] Removable connection methods can use screws, buckles, pins, etc. These connection methods can also ensure the stability and detachability of the connection.

[0031] As in Fig. As shown in Figure 4, the damping mechanism 400 includes an elastic block 401 mounted on the fixed plate 100. The elastic block 401 is elastic and can absorb the impact force generated when the rotating plate 200 abuts, thereby protecting the folding mechanism of the armrest. The damping mechanism 400 further includes a damping block 402 provided on the rotating plate 200, with the damping block 402 and the elastic block 401 arranged opposite one another. When the rotating plate 200 abuts, the damping block 402 and the elastic blocks 401 are in contact to ensure effective absorption of the impact forces.

[0032] In other embodiments, the specific shape, size, and material of the cushioning block 402 may also vary, but the most important point is that it must be able to work together with the elastic block 401 to jointly absorb the impact force. Therefore, the cushioning block can be replaced with other types of materials (e.g., rubber, plastic, etc.) or structures (e.g., protrusions, grooves, etc.) that form good contact with the elastic block 401 and provide additional cushioning.

[0033] How Fig. 1 and Fig. 2, an upper end of the rotary plate 200 is connected to a fixing band 500, and the other end of the fixing band 500 is connected to the upper end of the fixed plate 100. The fixing band 500 is an elastic band, and the fixing band 500 can limit the distance of the rotary plate 200 from the fixed plate 100 to prevent the distance between the rotary plate 200 and the fixed plate 100 from exceeding a reasonable range.

[0034] In other embodiments, the specific shape (such as material, width, length, etc.) of the fixation band 500 may vary. Therefore, other types of elastic materials (such as rubber bands, spring bands, nylon bands, etc.) may be used to replace the fixation band 500, and these materials may also be capable of providing similar retention properties to the fixation band 500.

[0035] As in Fig. 2, the upper end of the rotating plate 200 is provided with a handle 201 for easy gripping, and the handle 201 facilitates gripping the rotating plate 200, which makes it easier for the user to grip and rotate the rotating plate 200 to bring it from the folded state to the unfolded state.

[0036] As in Fig. As shown in Figure 5, the fixed plate 100 is detachably connected to one long side of the sofa. When unfolded, the fixed plate 100 and the rotating plate 200 can serve as supports for the armrest cushioning material. When folded, the fixed plate 100 can be removed, and the sofa armrest can be separated from the main body of the sofa, while reducing the space occupied by the armrest, which is convenient for storage and transportation.

[0037] In other embodiments, the specific shape, material, and position of the handle 201 may vary, but the key is that it provides a surface that is easy to grasp and to apply force to. Therefore, other types of structures (such as protrusions, grooves, grips, etc.) may be used to replace the handle 201, as long as they can provide similar functions to facilitate gripping.

[0038] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above-mentioned embodiments, but also include technical solutions consisting of any combination of the above-mentioned technical features. It should be noted that a person skilled in the art can make a number of improvements and refinements without deviating from the principles described in the utility model, and these improvements and refinements should also be considered within the scope of protection of the utility model.
