The invention discloses a strap-type folding chair, and belongs to the technical field of folding chairs according to the International Patent Classification (IPC).
A folding chair is a portable and foldable chair and can be carried to different places such as a beach, a park and a sports event site, and since the folding chair is foldable, space can be saved when the folding chair is carried or stored. A folding chair in China is generally not provided with a strap and consequentially inconvenient to carry. A foreign folding chair comprises a strap, however, the carrying forms achieved through the strap are simplex and cannot be changed, and only one fixed carrying form is available. For example, a backpack type chair disclosed in the document US RE39022 E comprises a chair frame, a backrest frame and a strap, wherein the strap is fixed to the chair frame, the chair can only be carried on the back with both shoulders through the strap, and use is limited.
For overcoming the defects of the prior art, the invention provides a strap-type folding chair, the carrying methods of the chair can be changed by additionally arranging a strap, and the strap-type folding chair has the advantages of being reasonable in structure, high in adaptability and the like.
For achieving the above purposes, the following technical scheme is adopted by the invention:
A strap-type folding chair comprises a backrest and a chair seat, wherein the backrest can be adjusted to be in a sitting state or a lying state relative to the chair seat and is provided with a back side, the back side is provided with a strap with an initial end and a final end, the strap penetrates through fixing belts at the top of the backrest, the initial end and the final end of the strap are connected to a chair frame respectively, and at least one end of the strap is detachably connected with the chair frame.
Furthermore, the initial end or the final end of the strap is detachably connected with the chair frame through a release buckle.
Furthermore, the two fixing belts are arranged at the positions, close to the top, of the back side of the backrest, the strap penetrates through the two fixing belts, and the junction of the initial end of the strap and the chair frame is spaced away from the junction of the final end of the strap and the chair frame by a certain distance.
Furthermore, the strap is matched with the fixing belts to form a double-shoulder carrying structure or a single-shoulder carrying structure or a hand carrying structure.
Furthermore, a buckle belt is arranged on the reverse side of the chair seat and connected with an insertion base, a buckle belt is arranged on the back side of the backrest and connected with an insertion head, and the insertion head and the insertion base are locked together to prevent the chair from being unfolded when the folding chair is folded.
Furthermore, the chair frame comprises a backrest frame and a chair seat frame, the backrest frame and the chair seat frame rotate in a pivoted mode, and the backrest frame is connected with a lying supporting leg.
Furthermore, a front leg frame and a rear leg frame are matched to support the chair seat frame and connected with armrests on both sides, and the rear ends of the armrests are connected to the backrest frame in an attached mode.
By combining the strap with chair fixing points, the strap-type folding chair of the invention can be carried on the back in various forms and has the advantages of being reasonable in structure, high in adaptability and the like.
A further description of the invention is given with accompanying drawings as follows:
Embodiment: please see
The sitting state mentioned above refers to the backrest 101 being approximately perpendicular to the chair seat 102 in position, and the lying state refers to the backrest 101 being approximately horizontal to the chair seat 102 in position.
As is shown in
Please see
The fixing belts 3 of the invention can be arranged on the backrest 101 or directly arranged on the chair frame 1, for example, a cross rod component of the backrest frame is provided with the fixing belts, and the junctions of the strap 2 and the chair frame 1 can be located at the bottoms of components on both sides of the backrest frame 11 or on both sides of the chair seat frame.
The buckle belt of the chair seat 102 is arranged on the chair seat frame 12 or directly connected to the chair seat 102, and similarly, the buckle belt of the backrest 101 can be arranged on the backrest or directly arranged on the chair frame 1.
The illustration of the scheme of the invention is as follows:
the fixing belts are sewn on the chair back or the backrest, the strap penetrates through the fixing belts, in this way, on the one hand, the strap cannot fall out, and on the other hand, the strap can lean against a face, and thus adjustment and conversion can be conducted. The other end of the strap is connected with the chair frame, the two sections of the strap are connected through a release buckle so that the strap can be dismounted conveniently and the length of the strap can be adjusted conveniently; two woven belts are sewn on the backrest and a cushion respectively, the woven belt on the backrest is connected with the insertion base, and the woven belt on the cushion is connected with the insertion head; when the chair is folded, the insertion head is matched with the insertion base, so that it is ensured that the chair is prevented from being unfolded when carried in a folded state.
By combining the strap with chair fixing points, the strap-type folding chair of the invention can be carried on the back in various forms and has the advantages of being reasonable in structure, high in adaptability and the like.
The strap-type folding chair of the invention has the following characteristics that:
1. The two sections of the strap are connected through the release buckle so that the strap can be dismounted conveniently and the length of the strap can be adjusted conveniently.
2. Different carrying methods such as a double-shoulder carrying method, a single-shoulder carrying method and a hand carrying method can be achieved by adjusting the strap.
3. The two fixing belts are sewn on the backrest, so that on the one hand, the strap is prevented from falling out, and on the other hand, the strap can lean against a face, and adjustment and conversion can be conducted.
4. The two woven belts are sewn on the backrest and the cushion respectively, the woven belt on the backrest is connected with the insertion base, the woven belt on the cushion is connected with the insertion head, the insertion head is matched with the insertion base when the chair is folded, and thus it is ensured that the chair is prevented from being unfolded when carried on the back in the folded state.
The strap-type folding chair of the invention aims to overcome the defect that in the prior art, a strap of a chair provided with the strap cannot be changed, and the chair can only be carried on the back in one fixed form. The folding chair of the invention is suitable for serving as a beach chair or other chairs with the same function.
The foregoing description only refers to the embodiment created according to the technical content of the invention, any modifications and changes made by those familiar with the technique of the invention are within the patent scope of claims by the invention, and the patent scope of the invention is not limited to the content disclosed by the embodiment.
