Description

Technical Field

[0001] The utility model relates to the technical field of seats, in particular to a foldable single chair which is convenient for storage. Background Art

[0002] Single chairs are common furniture in daily life. In order to make the single chair easier to store or transport, they are usually made into a foldable structure. However, the larger the single chair is, the more difficult it is to fold it, especially the folding of the backrest. The existing folding method is usually to directly hinge the backrest and the seat frame, and adjust the inclination angle of the backrest through the armrest. This setting method makes it impossible to completely fold the backrest. Moreover, this folding method makes the backrest have a lower supporting strength when in use, which affects the use effect of the single chair. Utility Model Content

[0023] Example

[0024] This embodiment provides a foldable single chair that is easy to store. Figure 1 , including a base frame 1 and a seat frame 3 connected thereto by a support rod 2, the rear side of the seat frame 3 is inclinedly provided with a backrest 4, a user can sit on the seat frame 3 and rest by leaning on the backrest 4, the structure of the single chair (the above-mentioned foldable single chair that is easy to store) is described in detail below.

[0025] In this embodiment, as one of the core technical concepts of the utility model, the support rod 2 is detachably connected to the base frame 1 and / or the seat frame 3, so that the seat frame 3 and the base frame 1 can be disassembled, thereby making the single chair easier to be stored.

[0026] As a preferred embodiment, in order to ensure the use effect of the single chair, the seat frame 3 includes two rod-shaped arc seats 11 arranged opposite to each other, a connecting rod 12 is connected between the two arc seats 11, and the two ends of the support rod 2 are respectively connected to the arc seats 11 and the seat frame 3.

[0027] In order to further ensure a single storage effect and reduce the storage space of the seat frame 3, the support rod 2 is configured to include a rod head 21 and a columnar rod body 22 at one end thereof, and is hingedly connected to the arc seat 11 through the rod head 21, and the rod body 22 is plugged and connected to the seat frame 3 at one end away from the rod head 21, so that when the base frame 1 is stored, the support rod 2 can be rotated to fit with the base frame 1.

[0028] As a further preferred embodiment, in order to ensure the use effect of the seat frame 3 and prevent it from tipping over backwards, a support head (not shown) is further provided at the lower side of the rear end of the two arc-shaped seats 11 .

[0029] In this embodiment, the seat frame 3 includes a horizontally arranged U-shaped first frame 31 with an opening facing backwards. A first inserting tube 32 is provided on the lower side of the first frame 31 , and the upper end of the rod body 22 of the support rod 2 is plug-connected with the first inserting tube 32 .

[0030] Of course, in order to ensure the use effect of the seat frame 3, the three support rods constituting the first frame 31 can also be an arc-shaped structure, and no specific limitation is made to the structure of the first frame 31 here.

[0031] In order to ensure the supporting effect of the support rod 2 and thus ensure the structural strength of the single chair when in use, four first inserts 32 are provided and are respectively arranged at the front and rear of both sides of the first frame 31 , and four corresponding support rods 2 are provided and are symmetrically arranged on the arc seats on both sides of the seat frame 3 .

[0032] In order to further ensure the supporting effect of the support rod 2, the front and rear first inserting tubes 32 located on the same side of the first frame 31 are tilted to point to the front lower part and the rear lower part of the first frame 31 respectively.

[0033] On the basis of the above structure, as another embodiment, the rod head 21 of the support rod 2 is hingedly connected to the arc seat 11 through the hinge seat on the arc seat 11, and at least one of the two hinge seats on the same arc seat 11 is configured to be able to slide along the length direction of the arc seat 11 and can be locked by a locking bolt. The support rod 2 can be configured as an electric telescopic cylinder to achieve the adjustment of the height of the seat frame 3, thereby further ensuring the use effect of the single chair.

[0034] In this embodiment, as another core technical concept of the utility model, second insert tubes 33 are obliquely provided on both sides of the rear end of the first frame 31, and the support frame 4 includes a U-shaped (also called n-shaped) second frame 41 with an opening downward, and the lower end of the second frame 41 is respectively plugged into and matched with two second insert tubes 33 on both sides.

[0035] Of course, in order to ensure the use effect of the support frame 4, the three support rods constituting the second frame 41 can also be an arc-shaped structure, and no specific limitation is made to the structure of the second frame 41 here.
