Description

Folding chair

Technical Field

The utility model relates to a seat field specifically relates to a folding chair.

Background

The folding chair is popular with people due to small occupied space and convenience, the structure of the existing folding chair (such as CN2561278Y) is mostly composed of four groups of scissors-shaped connecting rods and a backrest rod, the ends of the front and the rear scissors-shaped connecting rods are respectively connected with the ends of the left and the right scissors-shaped connecting rods, and the folding chair frame is formed after the connection with the backrest rod, and the folding chair frame can be completely folded into a storage state or opened into a use state through the closing and opening operations of the two cross rods of the scissors-shaped connecting rods; the folding chair can be completely folded, and the folded chair has small volume and is very suitable for being carried and used outdoors.

However, most of the backrest rods of the existing folding chair are straight rods, the backrest rods are located on the same horizontal plane from the top end to the bottom end, and after a person sits on the chair, the backrest rods on the two sides can contract inwards, so that the contact surface between the back of the person and the backrest is reduced, the back of the person is not in a stretching state directly, the comfort level of the backrest is affected, and the person feels tired even after long-time use.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a folding chair to solve the problem that the backrest rod of the existing folding chair contracts inwards after people sit.

The specific scheme is as follows:

Detailed Description

To further illustrate the embodiments, the present invention provides the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the embodiments. With these references, one of ordinary skill in the art will appreciate other possible embodiments and advantages of the present invention. Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.

The present invention will now be further described with reference to the accompanying drawings and detailed description.

As shown in fig. 1-3, the present embodiment provides a folding chair, a folding chair frame 1 and a piece of chair cloth 3, wherein the folding chair frame 1 comprises a front scissor type connecting rod 11, a rear scissor type connecting rod 12, a left scissor type connecting rod 13, a right scissor type connecting rod 14 and two oppositely arranged backrest rods 15. In the present embodiment, the front, rear, left, and right directions are based on the corresponding positions of the person seated in the seat.

The front scissor type connecting rod 11 is composed of two front rod bodies which are mutually hinged into an X shape, the upper ends of the two front rod bodies are respectively hinged with a front clamping piece 21 in a matching way, and the lower ends of the two front rod bodies are respectively hinged with a front foot pad 22 in a matching way. The lower ends of the two backrest rods 15 are respectively fixedly connected with a rear foot pad 23, and each backrest rod 15 is sleeved with a backrest rod sliding seat 24, and the backrest rod sliding seats 24 can slide on the respective backrest rods 15. The left scissor type connecting rod 13 is composed of two left rod bodies hinged into an X shape, the upper ends of the two left rod bodies are respectively hinged on the front clamping piece 21 and the back rod sliding seat 24 on the same side, and the lower ends of the two left rod bodies are respectively hinged on the front foot pad 22 and the back foot pad 23 on the same side. The right scissor type connecting rod 14 is composed of two right rod bodies which are hinged into an X shape, the upper ends of the two right rod bodies are respectively hinged on the front clamping piece 21 and the back rod sliding seat 24 which are arranged on the same side, and the lower ends of the two right rod bodies are respectively hinged on the front foot pad 22 and the rear foot pad 23 which are arranged on the same side. The rear scissor type connecting rod 12 is composed of two rear rod bodies hinged into an X shape, the upper ends of the two rear rod bodies are respectively hinged on the two back rod sliding seats 24, and the lower ends of the two rear rod bodies are respectively hinged on the two rear foot pads 23.

The folding and unfolding of the folding chair in the front and back directions are realized by the folding and unfolding of the left scissor type connecting rod 13 and the right scissor type connecting rod 14 in the front and back directions, and the folding and unfolding in the left and right directions are realized by the folding and unfolding of the front scissor type connecting rod 11 and the rear scissor type connecting rod 12 in the left and right directions, so that the folding chair has the functions of being folded into a storage state and being unfolded into a use state.

The folding mechanism of the folding chair is only one specific example provided in this embodiment, but not limited thereto, and may be other folding mechanisms capable of achieving the same function, such as the folding mechanism disclosed in chinese patent CN205548040U by the applicant.

The folding chair provided by the embodiment is different from the existing folding chair in that the two backrest rods 15 are provided with the bending sections 151 at the middle upper sections corresponding to the backrest, and the bending sections 151 enable the upper ends of the backrest rods 15 to be outwards expanded relative to the lower ends, so that the width between the upper ends of the two backrest rods 15 is larger than the width between the lower ends of the two backrest rods 15, the backrest is enabled to be outwards opened, the backrest rods on the two sides cannot be inwards contracted after a person sits on the backrest when the person uses the folding chair, the backrest of the person is in an extended state when the backrest leans against the backrest, the folding chair is more in line with human engineering, and the overall comfort level of the folding chair is improved.

In some embodiments, the bending section 151 divides the backrest rod 15 into a first straight line section 152 and a second straight line section 153, which are vertically arranged, wherein the first straight line section 152 is located at the lower end of the bending section 151, and the second straight line section 153 is located at the upper end of the bending section. The distance between the first straight sections 152 of the two backrest levers 15 is defined as L1, and the distance between the second straight sections 153 of the two backrest levers 15 is defined as L2, wherein L1 < L2. That is, the bending section 151 is formed by bending the backrest rod 15 at least twice, and is bent inward again after being bent outward for a certain distance for the first time, so that at least two bending structures are formed at the middle-upper section of the backrest rod 15, thereby further ensuring that the backrest rods at two sides cannot contract inward after a person sits on the seat, and improving the comfort level of the person sitting on the seat.

Preferably, the two back-rest bars 15 are arranged in mirror image, so as to facilitate the manufacturing and molding of the two back-rest bars.

In some embodiments, the upper ends of the two front rods of the front scissor type connecting rod 11 pass through the respective hinged front clamping pieces 21 and are bent in the left and right directions to form the armrest fixing part 111, so that the front scissor type connecting rod 11 can be directly used as an armrest rod, and the folding chair can have the armrest 30, thereby further improving the comfort level of people sitting in the chair.

The armrests 30 may be soft armrests formed directly from chair cloth as in fig. 3, or hard armrests formed from hard plastic, which have the advantage of being foldable directly in synchronization with the chair cloth, but with less comfort than hard armrests; although the hard armrests have higher comfort level, the hard armrests cannot be folded synchronously with the chair cloth, and extra folding and mounting steps are needed.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
