TECHNICAL FIELD

The present disclosure relates to the technical field of outdoor equipment, and in particular to a portable folding chair.

BACKGROUND

With the rapid development of economy and society, people's requirements for quality of life are increasingly high. Outdoor leisure activities such as road trips are gaining growing popularity, and folding chairs serve as essential equipment for outdoor recreational activities.

However, existing folding chairs have the following shortcomings in use. First, most of the chair frames lack armrests, and those with armrests suffer from poor support reliability and poor portability after being folded. Second, the existing folding chairs only provide the basic function of sitting. They lack a rocking function, and their backrests lack adjustable angles, resulting in poor use comfort.

In view of these shortcomings, the present disclosure designs a portable folding chair with improved use comfort.

DETAILED DESCRIPTION OF THE EMBODIMENTS

The technical solutions in the embodiments of the present disclosure will be described below clearly and completely with reference to the drawings in the embodiments of the present disclosure. Apparently, the described embodiments are merely some, rather than all of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.

Embodiment 1

As shown in FIG. 1, this embodiment provides a portable folding chair. The portable folding chair includes backrest 1 and chair frame 2.

In this embodiment, the backrest 1 includes backrest body 11. The backrest body is divided into a seat area and a backrest area. Two sides of the backrest body 11 in the seat area are connected to ribbons 12, respectively.

In this embodiment, backrest connecting strip 13 is provided between a rear end of the ribbon 12 and a side portion, adjacent to the rear end of the ribbon 12, of the backrest area of the backrest body 11. The backrest connecting strip 13 has a fixed or adjustable length. The backrest 1 is adjustable at different angles, improving overall use comfort.

In this embodiment, seat connecting strip 14 is provided between a rear end of the ribbon 12 and a rear end, adjacent to the rear end of the ribbon 12, of the seat area of the backrest body 11. The seat connecting strip 14 has a fixed or adjustable length.

In this embodiment, the two sides of the backrest body 11 in the seat area are respectively provided with seat fabric supports to prevent gathering of a seat area fabric. The seat fabric supports can also prevent gathering of the front and rear ribbons 12.

As shown in FIGS. 2 to 4, the chair frame 2 includes two armrest members 21, and folding structure 22 capable of being folded and unfolded is provided between the two armrest members 21. The armrest members 21 each include armrest portion 211 and support rod portions 212 provided at two sides of the armrest portion.

In this embodiment, a bottom end of each of the support rod portions 212 is provided with support foot 213, and reinforcing crossbar 214 is provided between the two support rod portions 212 of each armrest member 21.

In this embodiment, the folding structure 22 includes two U-shaped rods 221 and four straight rods 222. Side rods of the two U-shaped rods 221 are hinged via first pin shafts, respectively. Outer ends of the side rods of the two U-shaped rods 221 each are hinged via a second pin shaft to the adjacent support rod portion 212 of the armrest member 21. Positions of the side rods of each of the two U-shaped rods 221 close to an intermediate connecting rod are respectively hinged via third pin shafts to ends of two straight rods 222 at a corresponding side. The other ends of the two straight rods 222 at the corresponding side are respectively hinged via third pin shafts to the adjacent support rod portions 212 of the armrest member 21.

In this embodiment, the ribbon 12 of the backrest 1 is directly fixedly connected to the armrest portion 211 of the armrest member 21.

In this embodiment, an armrest cover is sleeved on an outer side of the armrest portion 211 of the armrest member 21. The armrest cover is wrapped on the outer side of the armrest portion 211 via a hook-and-loop fastener or other means, improving the comfort of armrest support and overall aesthetics. Additionally, functional components such as a storage area may be provided on the armrest cover.

In a practical application of this embodiment, the portable folding chair has a rational structural design, including the backrest 1 and the chair frame 2. The backrest body 11 of the backrest 1 is divided into the seat area and the backrest area. The two sides of the backrest body 11 in the seat area are respectively connected to the ribbons 12. The chair frame 2 includes two armrest members 21 and the folding structure 22 capable of being folded and unfolded. The ribbon 12 of the backrest 1 is connected to the armrest portion 211 of the armrest member 21. The two armrest members 21 of the chair frame 2 provide reliable support for the backrest 1, and the chair frame 2 becomes easy to carry after being folded. The portable folding chair provides the basic function of sitting, and enables a rocking function.

Embodiment 2

This embodiment is improved based on Embodiment 1, and the improvements are shown in FIG. 5. In the folding structure 22, outer ends, close to the armrest member 21, of the two straight rods 222 at the same side are connected together to jointly serve as a pull and press rod for folding or unfolding of the chair frame 2.

Compared with Embodiment 1, the chair frame 2 in this embodiment facilitates chair folding.

Embodiment 3

The difference between this embodiment and Embodiment 1 is shown in FIG. 6. The ribbon 12 of the backrest 1 is fixedly connected to the armrest portion 211 of the armrest member 21 via bolt 3.

Embodiment 4

The difference between this embodiment and Embodiment 3 is shown in FIG. 7. The ribbon 12 of the backrest 1 is detachably connected to the armrest portion 211 of the armrest member 21 via hook 4. The armrest portion 211 is provided with a suspension support member to facilitate hook hanging.

In this embodiment, the suspension support member may select the bolt 3 provided in Embodiment 3 or other structures such as a hanging ring. If the bolt 3 is adopted, it mainly matches Embodiment 3 and facilitates mass production and modular design.

In Embodiments 1 to 3, the backrest 1 and the chair frame 2 are of an integrated structure and non-detachable. In this embodiment, the backrest 1 and the chair frame 2 are of a split structure and detachable.
