Description

Technical Field

[0001] The utility model relates to the technical field of chairs, in particular to a detachable chair. Background Art

[0002] During the transportation of chairs, they occupy a large area, so the freight is high. In addition, due to the three-dimensional structure of chairs, they are prone to being knocked and damaged during transportation. Therefore, many foldable chairs have emerged on the market, enabling chairs to be folded and compressed during transportation to reduce the space occupied by the chairs. However, the structure of foldable chairs is complex, and the processing and installation costs are high. In addition, after being folded multiple times, the components of foldable chairs are prone to damage, making the foldable chairs unable to be used anymore. Integrally formed chairs are not conducive to transportation. Therefore, detachable chairs can greatly reduce the space occupied by chairs during transportation, reduce logistics costs, and reduce the damage of chairs due to being knocked during transportation.

[0003] The technical content disclosed in the Chinese patent document (publication number: CN211021758U, patent name: Chair that can be automatically unfolded) is as follows: A chair that can be automatically unfolded is provided, including a seat and a backrest. The backrest is hinged to the rear end of the seat. The front end and the rear end of the seat are respectively provided with a front leg and a rear leg. The backrest and the seat are detachably connected with a shape memory metal one and a shape memory metal two respectively in the closed and unfolded states. The shape memory metal one and the shape memory metal two are deformed by heat to drive the backrest and the seat to unfold and close. This application utilizes the characteristics of shape memory metals deforming by heat and returning to their normal state when cooled to complete the unfolding and closing of the chair. The operation is simple and convenient. In the closed state, heat the shape memory metal one to make it deform and unfold the backrest and the seat. At this time, place the shape memory metal two between the backrest and the seat to keep the chair in the unfolded state. In the unfolded state, heat the shape memory metal two to make it deform and close the backrest and the seat. At this time, place the shape memory metal one between the backrest and the seat to keep the chair in the closed state.

[0004] As can be seen from the above implementation, the chair can be folded to compress the storage space. However, the chair has many components, and the installation is very complex. If the components are damaged after use, it is difficult for users to repair them. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The following describes the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0027] As Figures 1 to 4 shown, a detachable chair includes a detachable connected seat board 1, a backrest board 2 and armrests 3. The backrest board 2 is inserted into one end of the seat board 1, and both sides of the seat board 1 and the backrest board 2 are connected to the armrests 3; after disassembly, the seat board 1, the backrest board 2 and the armrests 3 are all equivalent to flat plates with a certain thickness. When transporting, only need to stack the seat board 1, the backrest board 2 and the armrests 3 together for packaging, which greatly saves the storage space occupied by the chair during transportation. In addition, stacking the various components together for packaging is also beneficial to protecting the various components and avoiding deformation of the components due to collision.

[0028] A number of seat board connection holes 301 are provided on the first connecting cross bar 304, and a seat board connection hole 301 is provided at one end of the second connecting cross bar 307 away from the front foot 305. When installing the seat board 1, the backrest 2 and the armrest 3, only need to insert the insertion rod 201 of the backrest 2 into the insertion hole 101 of the seat board 1, then use a bolt to pass through from the side of the bottom of the seat board 1 and lock it at the backrest connection hole 302 of the armrest 3, and then use a bolt to pass through from the rear of the backrest 2 and lock it at the backrest connection hole 302 of the armrest 3, then the armrest can be locked on both sides. Therefore, ordinary users can also install the chair, eliminating the need for the seller to install and debug it in advance before shipping, reducing the installation cost.

[0029] The seat board 1 is provided with an insertion hole 101, and the insertion hole 101 forms an angle less than 90 degrees with the upper surface of the seat board 1. The distance between the lower end of the insertion hole 101 and the backrest 2 is greater than the distance between the upper end of the insertion hole 101 and the backrest 2. The lower end of the backrest 2 is connected with an insertion rod 201. Therefore, after the insertion rod 201 of the backrest 2 is inserted into the insertion hole 101, the backrest 2 will be in a state of tilting backward. In this way, when a person sits on the seat board 1, they can recline backward on the backrest 2.

[0030] The armrest 3 includes a first connecting cross bar 304 and a second connecting cross bar 307 arranged in parallel. One end of the first connecting cross bar 304 and the second connecting cross bar 307 is vertically connected with a front foot 305, and the other end of the first connecting cross bar 304 and the second connecting cross bar 307 away from the front foot 305 is connected with a rear foot 306. An angle less than 90 degrees is formed between the front foot 305 and the rear foot 306. The distance between the upper end of the rear foot 306 and the front foot 305 is less than the distance between the lower end of the rear foot 306 and the front foot 305. Then the rear foot 306 extends backward and downward relative to the seat board 1. When a person reclines on the backrest 2, the center of gravity of the person moves downward and backward of the chair. Therefore, the setting of the rear foot 306 can well support the weight of the human body, making the seat more stable.

[0031] On the side of the front foot 305 and the second connecting cross bar 307 away from the seat board 1, a clearance inclined surface 303 is provided. The clearance inclined surface 303 can play a role in decorating the appearance of the armrest 3, making the appearance of the chair look better. On the other hand, compared with the front foot 305 and the second connecting cross bar 307 with a square cross-section, the provided clearance inclined surface 303 makes the front foot 305 and the second connecting cross bar 307 use less material, also saving the processing material cost of the chair. Moreover, the armrest 3 is made of aluminum alloy casting. When casting and processing, demoulding is required. The clearance inclined surface 303 is more conducive to demoulding after the armrest 3 is poured.

[0032] In this embodiment, the insertion rod 201 is threadedly connected to the backrest 2. Therefore, if the insertion rod 201 is damaged during use, the insertion rod 201 can be replaced separately, without the backrest 2 being unable to continue to be used due to the damage of the insertion rod 201.

[0033] There is at least one support cross-bar 102 provided on the seat board 1, and a reinforcing support bar 103 is provided below the support cross-bar 102. The reinforcing support bar 103 is vertically arranged with respect to the support cross-bar 102. When a person sits down, the support cross-bar 102 plays a supporting role for the person, and the reinforcing support bar 103 supports the bottom of the support cross-bar 102, so that the support cross-bar 102 will not be deformed due to long-term stress.

[0034] The backrest 2 is provided with a number of backrest cross-bars 202, and a gap is formed between every two backrest cross-bars 202. Therefore, when a person leans on the backrest 2, the back of the person will not feel stuffy due to leaning on the backrest for a long time.

[0035] The seat board 1, the backrest 2, and the armrest 3 are all made of aluminum alloy. Compared with a stainless-steel chair, the aluminum alloy is lighter, making the overall mass of the chair smaller. And compared with a plastic chair, the chair made of aluminum alloy is stronger in bearing force and has better durability in use.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
