Abstract
Description
Technical Field
[0001] The utility model relates to the field of outdoor product structures, and more particularly to a dual-purpose folding chair. Background Art
[0002] A folding chair generally includes two mutually hinged frame members. A front leg rod, a rear leg rod, a front seat rod, and a backrest rod are inserted into the frame members. Among them, an elastic cable is used to connect the front leg rod and the front seat rod, and an elastic cable is used to connect the rear leg rod and the backrest rod.
[0003] In order to facilitate the folding and closing of the folding chair, the two frame members can be relatively unfolded and folded. The frame members generally include a rotating disc and a rotating arm. The rotating discs of the two frame members are rotatably connected. Through understanding of related technologies, although some folding chairs have folding and unfolding states, some folding chairs have a single use scenario. Usually, when a folding chair used on a hard ground is used on a beach, there is a problem that the four feet are easily embedded in the sand layer. And when the four support feet are not evenly stressed, there is a phenomenon that the embedding depths of the respective support feet are different, resulting in tipping. Summary of the Utility Model
[0004] The purpose of at least one specific embodiment of the present utility model is to solve the defects existing in the prior art and provide a dual-purpose folding chair.
[0005] To achieve the above object, a dual-purpose folding chair provided by the present application includes:
[0006] Two or more mutually hinged frame members;
[0007] A front leg rod, a rear leg rod, a front seat rod, and a backrest rod inserted into the frame members;
[0008] Support feet detachably installed at the joints of the front leg rod, the rear leg rod, and the frame members;
[0009] A seat pocket supported at its four corners by two front seat rods and two backrest rods respectively;
[0010] The front leg rod and the rear leg rod are connected to the frame member through an easy-to-expand structure. When the front leg rod and the rear leg rod are unfolded relative to the frame member, the folding chair is in the first use state;
[0011] When the front leg rod and the rear leg rod are folded relative to the frame member, the support feet are installed at the joints of the front leg rod, the rear leg rod, and the frame member, and the folding chair is in the second use state.
[0012] Further, one end of the support foot is provided with an insertion opening. When the folding chair is in the second use state, the front leg rod and the rear leg rod are folded relative to the frame member, and one end of the frame member is inserted into the insertion opening of the support foot, and the support foot supports at the bottom of the folding chair.
[0013] Furthermore, a support guiding groove is provided on the inner wall of the insertion interface, and a support guiding block corresponding to the support guiding groove is provided on the surface of the frame member. When the support foot is inserted relative to the frame member, the support guiding block is inserted into the support guiding groove.
[0014] Furthermore, a limiting opening is provided on the support foot. After the support foot is inserted into the frame member, the limiting opening restricts the rotation of the front leg rod and the rear leg rod, so that the front leg rod and the rear leg rod are kept in a folded state.
[0015] Furthermore, the number of the support feet is multiple, and two relatively arranged support feet are connected by a reinforcing support plate, and the two reinforcing support plates are hinged to each other.
[0016] Furthermore, when the folding chair is in the first use state, the ends of the front leg rod and the rear leg rod away from the frame member contact the ground;
[0017] When the folding chair is in the second use state, the ends of the support feet away from the frame member contact the ground;
[0018] Wherein, the contact area between the support foot and the ground is larger than the contact areas between the front leg rod, the rear leg rod and the ground.
[0019] Furthermore, the easy-to-expand structure includes:
[0020] An insertion part, which is arranged on the frame member;
[0021] An insertion end, which is arranged at the ends of the front leg rod and the rear leg rod;
[0022] A pivot, which is arranged on one of the insertion part and the insertion end;
[0023] A guiding groove corresponding to the pivot is provided on the other of the insertion part and the insertion end, and the pivot is in sliding fit with the guiding groove;
[0024] When the pivot slides to one end of the guiding groove, the support rod is in the first assembly state, and the support rod is stopped relative to the insertion part;
[0025] When the pivot slides to the other end of the guiding groove, the support rod is in the second assembly state, and the support rod can rotate with the insertion part.
[0026] Furthermore, an avoidance opening is provided on the insertion part. When the support rod is in the second assembly state and rotates with the insertion part, the avoidance opening provides the avoidance space required for the support rod to rotate out of the insertion part to the insertion end.
[0027] Furthermore, one end of the guiding groove is the first limiting end, and the other end is the second limiting end;
[0028] When the pivot slides to the first limit end of the guide groove, the support rod is in the first assembled state, the insertion end of the support rod extends into the insertion part, and the support rod is stopped relative to the insertion part;
[0029] When the pivot slides to the second limit end of the guide groove, the support rod is in the second assembled state, the insertion end of the support rod is withdrawn from the insertion part, and the insertion end can rotate in the avoidance space with the pivot as the center, and the support rod can rotate relative to the insertion part.
[0030] Furthermore, the folding chair further includes:
[0031] A first cable, one end of which extends into the front leg rod and is connected thereto, and the other end extends into the front seat rod and is connected thereto;
[0032] A second cable, one end of which extends into the rear leg rod and is connected thereto, and the other end extends into the backrest rod and is connected thereto.
[0033] The beneficial effects of the present utility model are as follows: when the front leg rod and the rear leg rod of the folding chair are unfolded relative to the frame member, the folding chair is in the first use state, and at this time, the folding chair is supported by the front leg rod and the rear leg rod unfolded at the bottom; when the front leg rod and the rear leg rod are folded relative to the frame member, the support feet are inserted at the connection between the front leg rod, the rear leg rod and the frame member, and the folding chair is in the second use state. When the front leg rod and the rear leg rod are in the folded state, the folding chair is supported and used by the support feet at the four corners of the bottom. When the folding chair is in the first use state, it can be used as an ordinary outdoor folding chair. When the folding chair is in the second use state, the contact area of each support foot with the ground is relatively large, and it can be used as a beach chair with a lower center of gravity. When each support foot contacts the sand layer, it is not easy to have serious depression of the sand layer or uneven depression of the four support feet. Therefore, the folding chair can not only be folded and retracted, but also has two different use states in different scenarios, meeting different outdoor use requirements.

[0045] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.
[0046] Embodiment 1
[0047] Referring to Figure 1 , Figure 2 , Figure 5 , a two - purpose folding chair 100 includes two or more mutually hinged frame members 10, front leg rods 11, rear leg rods 12, front seat rods 13 inserted on the frame members 10, and a backrest rod 14, a seat pocket 20 supported by two front seat rods 13 and two backrest rods 14 at the four corners respectively, and support feet 30 detachably installed at the joints of the front leg rods 11, rear leg rods 12 and the frame members 10;
[0048] In addition, the folding chair 100 further includes:
[0049] The first cable 15 has one end extending into and connecting with the front leg rod 11, and the other end extending into and connecting with the front seat rod 13.
[0050] The second cable 16 has one end extending into and connecting with the rear leg rod 12, and the other end extending into and connecting with the rear back rod 14.
[0051] In this embodiment, the front leg rod 11, the rear leg rod 12, the front seat rod 13, and the rear back rod 14 are connected to the frame member 10 through an easy - unfolding structure 40. When the front leg rod 11 and the rear leg rod 12 are unfolded relative to the frame member 10, the folding chair 100 is in the first use state. It should be noted that in this embodiment, the easy - unfolding structure 40 is mainly to facilitate the folding of the front leg rod 11, the rear leg rod 12, the front seat rod 13, and the rear back rod 14 relative to the frame member 10, but the specific structure of the easy - unfolding structure 40 is not specifically limited.
[0052] When the front leg rod 11 and the rear leg rod 12 are folded relative to the frame member 10, the support feet 30 are installed at the connection between the front leg rod 11, the rear leg rod 12 and the frame member 10, and the folding chair 100 is in the second use state.
[0053] Furthermore, one end of the support foot 30 is provided with an insertion interface 301. When the folding chair 100 is in the second use state, the front leg rod 11 and the rear leg rod 12 are folded relative to the frame member 10, and one end of the frame member 10 is inserted into the insertion interface 301 of the support foot 30. The support foot 30 supports at the bottom of the folding chair 100, and wraps the connection between the front leg rod 11 or the rear leg rod 12 and the frame member 10. During use, it can prevent the offset caused by the force at the connection between the front leg rod 11 and the rear leg rod 12 and the frame member 10, resulting in a situation where the front leg rod 11 and the rear leg rod 12 cannot be opened with the frame member 10.
[0054] Specifically, when the folding chair is in the first use state, the ends of the front leg rod 11 and the rear leg rod 12 far from the frame member 10 contact the ground.
[0055] When the folding chair is in the second use state, the ends of the support feet 30 far from the frame member 10 contact the ground.
[0056] Among them, the contact area of the support feet 30 with the ground is larger than the contact area of the front leg rod 11 and the rear leg rod 12 with the ground. When the folding chair is in the second use state, it can be used as a beach chair. Since the contact area of each support foot 30 with the ground is large, when each support foot 30 contacts the sand layer, it is not easy to have a serious depression in the sand layer or an uneven depression of the four support feet 30.
[0057] Furthermore, referring to Figure 3 , Figure 4, in some embodiments, a support guiding groove 302 is provided on the inner wall of the insertion interface 301, and a support guiding block 101 corresponding to the support guiding groove 302 is provided on the surface of the frame member 10. When the support leg 30 is inserted relative to the frame member 10, the support guiding block 101 is inserted into the support guiding groove 302, and the support guiding groove 302 can provide a stable supporting force to the frame member 10 through the support guiding block 101.
[0058] Further, a limiting port 303 is provided on the support leg 30. After the front leg rod 11 and the rear leg rod 12 are folded relative to the frame member 10, the support leg 30 is inserted into the frame member 10, and the limiting port 303 can limit the rotation of the front leg rod 11 and the rear leg rod 12, so that the front leg rod 11 and the rear leg rod 12 remain in the folded state.
[0059] Further, referring to Figures 6 to 9 , the easy-expansion structure 40 includes a plugging portion 401 provided on the frame member 10, a support rod 402 rotatably mounted on the frame member 10, one end of the support rod 402 is an insertion end 403, and the insertion end 403 is adapted to be inserted into the plugging portion 401;
[0060] Further, a pivot 404 is provided on one of the plugging portion 401 and the insertion end 403, and a guiding groove 405 corresponding to the pivot 404 is provided on the other of the plugging portion 401 and the insertion end 403, and the pivot 404 is in sliding fit with the guiding groove 405;
[0061] Further, one end of the guiding groove 405 is a first limiting end 406, and the other end is a second limiting end 407;
[0062] When the pivot 404 slides to the first limiting end 406 of the guiding groove 405, the support rod 402 is in the first assembly state, the insertion end 403 of the support rod 402 extends into the plugging portion 401, and the support rod 402 is stopped relative to the plugging portion 401;
[0063] When the pivot 404 slides to the second limiting end 407 of the guiding groove 405, the support rod 402 is in the second assembly state, the insertion end 403 of the support rod 402 is withdrawn from the plugging portion 401, the insertion end 403 can rotate around the pivot 404, the support rod 402 can rotate relative to the plugging portion 401, and an avoidance port 408 is provided on the plugging portion 401. When the support rod 402 is in the second assembly state and the support rod 402 rotates with the plugging portion 401, the avoidance port 408 provides the avoidance space required for the insertion end 403 to rotate out of the plugging portion 401.
[0064] In this embodiment, the support rod 402 is configured as the front leg rod 11, the rear leg rod 12, the front seat rod 13, and the backrest rod 14 of the folding chair 100. After each rod is connected to the frame member 10 by the easy-expansion structure 40, it can be freely folded and retracted.
[0065] When the easy - unfolding structure is in use, during the conversion process of the support rod 402 from the folded state to the unfolded state, there is no need for manual docking between the insertion end 403 of the support rod 402 and the insertion part 401 of the frame member 10. Through the cooperation of the pivot 404 and the guide groove 405, after the support rod 402 is unfolded, its insertion end 403 can automatically align with the insertion part 401, making the assembly between the support rod 402 and the frame member 10 convenient and efficient.
[0066] In addition, a first cable 15 is connected between the front foot rod 11 and the front seat rod 13, and a second cable 16 is connected between the rear foot rod 12 and the rear back rod 14. The first cable 15 and the second cable 16 are elastic. When the support rod 402 is in the folded state, the first cable 15 and the second cable 16 are in a stretched state. When the support rod 402 is converted from the folded state to the unfolded state, under the elastic tension of the first cable 15 and the second cable 16, the insertion end 403 of the support rod 402 will automatically insert into the insertion part 401. Through the cooperation of the pivot 404 and the guide groove 405, and the structural design of the elastic members (the first cable 15 and the second cable 16), when the support rod 402 (the front foot rod 11, the rear foot rod 12, the front seat rod 13, and the rear back rod 14) is in the folded state and the external constraints are removed, the support rod 402 (the front foot rod 11, the rear foot rod 12, the front seat rod 13, and the rear back rod 14) can achieve automatic alignment and automatic insertion with the insertion part 401 of the frame member 10.
[0067] In summary, when the front foot rod 11 and the rear foot rod 12 of the folding chair 100 are unfolded relative to the frame member 10, the folding chair 100 is in the first use state. At this time, the folding chair 100 is supported by the front foot rod 11 and the rear foot rod 12 that are unfolded at the bottom. In this case, the folding chair 100 is used as an outdoor folding chair.
[0068] When the front foot rod 11 and the rear foot rod 12 are retracted relative to the frame member 10, the support feet 30 can be inserted at the connection between the front foot rod 11, the rear foot rod 12 and the frame member 10. The folding chair 100 is in the second use state. When the front foot rod 11 and the rear foot rod 12 are in the retracted state, the folding chair 100 is supported and used by the support feet 30 at the bottom. When the folding chair is in the first use state, it can be used as an ordinary outdoor folding chair. When the folding chair is in the second use state, the contact area between each support foot 30 and the ground is large, and it can be used as a beach chair with a low center of gravity. When each support foot 30 contacts the sand layer, it is not easy to have a serious depression in the sand layer or an uneven depression of the four support feet 30. Therefore, this folding chair can not only be folded and retracted, but also has two different use states in different scenarios, meeting different outdoor use requirements.
[0069] Embodiment 2
[0070] Reference Figure 10 Figure 10 , based on the same technical concept, the number of support feet 30 is multiple. In this embodiment, two relatively arranged support feet 30 are connected by a reinforcing support plate 50. The middle parts of adjacent reinforcing support plates 50 are hinged to each other by pins. The structural design of the mutually hinged reinforcing support plates 50 is mainly to connect multiple support feet 30 into a whole to ensure the support strength of multiple support feet 30 at the bottom of the folding chair 100. Moreover, after the middle part and the end part of the reinforcing support plate 50 are connected in a hinged manner, when the folding chair 100 is folded, the reinforcing support plate 50 can be folded together with the frame member 10.
[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features.
