Description

Technical Field

[0001] This utility model relates to the field of outdoor products, and in particular to a folding chair that can be used by both humans and pets. Background Technology

[0002] As living standards improve, more and more people are keeping pets, and they are more willing to bring their pets along when engaging in outdoor activities. Currently, traditional folding chairs for people and folding beds for pets are separate, which means that people and pets are separated during use, resulting in limited interaction. In addition, they also need to be handled separately when unfolding and storing, making it impossible to unfold or store the folding chair and pet folding bed at the same time. Furthermore, because the folding chair and pet folding bed are separate, the structure is not compact, and they occupy a lot of space when used and stored. Utility Model Content

[0024] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0025] refer to Figures 1 to 3In some embodiments, a folding chair for both humans and pets includes: a first folding linkage mechanism 1 and a second folding linkage mechanism 2. The first folding linkage mechanism 1 includes a first front crossbar assembly 11 located on the front facade and a first rear crossbar assembly 12 located on the rear facade. The second folding linkage mechanism 2 includes a second front crossbar assembly 21 located on the front facade, a second rear crossbar assembly 22 located on the rear facade, a third seat post 24, and a fourth seat post 25. A pivot 26 is provided at the middle of the third seat post 24 and the middle of the fourth seat post 25, such that when the folding chair is in a folded state, the third seat post 24 and the fourth seat post 25 bend relative to themselves. A center seat post 3; a first joint pivot point A, a second joint pivot point B, and a third joint pivot point C; one lower end of the first front crossbar assembly 11 is connected to the second... One lower end of the front cross-bracing rod assembly 21 and the lower end of the third seat post 24 are pivotally connected to the first joint pivot point A. One lower end of the first rear cross-bracing rod assembly 12, one lower end of the second rear cross-bracing rod assembly 22, and the lower end of the center seat post 3 are pivotally connected to the second joint pivot point B. One upper end of the first front cross-bracing rod assembly 11, one upper end of the second front cross-bracing rod assembly 21, and the upper end of the center seat post 3 are pivotally connected to the third joint pivot point C. The first folding linkage mechanism 1 and the second folding linkage mechanism 2 can pivot relative to each other around the center seat post 3 through the first joint pivot point A, the second joint pivot point B, and the third joint pivot point C, so that the human-pet shared folding chair can switch between the unfolded use state and the folded storage state.

[0026] It is understood that the first folding linkage mechanism 1 is used to support humans, and the second folding linkage mechanism 2 is used to support pets. The first front crossbar group 11, the first rear crossbar group 12, the second front crossbar group 21, and the second rear crossbar group 22 are each composed of two support rods, with the centers of the two support rods rotatably connected to each other. Therefore, each crossbar group has two upper ends and two lower ends. The structure of the first folding linkage mechanism 1 and the second folding linkage mechanism 2 allows for linked folding and unfolding movements, and is simple and effortless to operate. When unfolded, they provide stable support for humans or pets. Since the first folding linkage mechanism 1 and the second folding linkage mechanism 2 are jointly connected to the first joint pivot point A, the second joint pivot point B, the third joint pivot point C, and the central seat rod 3, when the first folding linkage mechanism 1 is folded, the second folding linkage mechanism 2 will be folded simultaneously, and vice versa. Therefore, the folding and storage process of the shared human-pet folding chair becomes easier. When storing and moving, it can be operated simultaneously without separate operations, saving manpower and space, and improving people's outdoor camping experience. The pivot 26 set on the third seat post 24 and the fourth seat post 25 allows the third seat post 24 and the fourth seat post 25 to bend further after the shared human-pet folding chair is folded, thereby reducing storage space and making the structure of the folding chair more compact. After bending, the protruding length is reduced, avoiding scratching people or pets.

[0027] refer to Figures 1 to 3 In some embodiments, a transverse strut 6 is provided on the second rear cross strut assembly 22. The transverse strut 6 includes a first segment 61 and a second segment 62. One end of the first segment 61 and the second segment 62 are pivotally connected. The distal ends of the first segment 61 and the second segment 62 are respectively pivotally connected to the two rods of the second rear cross strut. The transverse strut 6 has: a locked position: when the second rear cross strut assembly 22 is in the unfolded state, the transverse strut 6 is pressed downward to straighten the first segment 61 and the second segment 62 collinearly, forming a rigid support for the second rear cross strut assembly 22; and an unlocked position: when the middle of the transverse strut 6 is lifted upward, the first segment 61 bends relative to the second segment 62, releasing the constraint on the second rear cross strut assembly 22.

[0028] Preferably, the transverse support rod 6 is pivotally connected in the middle, with both ends connected to the upper parts of the two rods of the second rear cross support rod assembly 22, i.e., above the center connection point of the two rods, and the connection points are on the same horizontal line. Alternatively, it can be connected to the lower parts of the two rods, i.e., below the center connection point of the two rods, and the connection points are on the same horizontal line. The transverse support rod 6 can be bent upwards, i.e., in the unlocked position, for easy storage of the folding chair. However, in the locked position, it can only be unfolded until the first rod segment 61 and the second rod segment 62 are collinear, and cannot be bent downwards further. Therefore, in the locked position, it can provide lateral rigid support to the second rear cross support rod assembly 22, making it less likely to fold when the folding chair is subjected to lateral force. It is understandable that, since the human-pet folding chair is designed to fold and unfold simultaneously, a horizontal support rod 6 can be installed on one of the cross support rod groups to provide support. The horizontal support rod 6 can also be installed on the first front cross support rod group 11, or on the first rear cross support rod group 12, or on the second front cross support rod group 21. Alternatively, a horizontal support rod 6 can be installed on each of the four cross support rod groups, or on two or three of the cross support rod groups.

[0029] refer to Figures 1 to 3In some embodiments, the first folding linkage mechanism 1 includes: a first backrest rod 13 and a second backrest rod 14, the lower ends of the first backrest rod 13 and the second backrest rod 14 being pivotally connected to the two lower ends of the first front crossbar assembly 11, and the upper ends of the first backrest rod 13 and the second backrest rod 14 being pivotally connected to the two upper ends of the first rear crossbar assembly 12; a first seat rod 15, the upper ends of the first seat rod 15 and the upper ends of the central seat rod 3 being pivotally connected to the two upper ends of the first front crossbar assembly 11, and the lower ends of the first seat rod 15 and the central seat rod 3 being pivotally connected to the two lower ends of the first rear crossbar assembly 12, wherein one lower end of the first front crossbar assembly 11 and the lower end of the second backrest rod 14 are pivotally connected to the first joint pivot point A, and one lower end of the first rear crossbar assembly 12 is pivotally connected to the second joint pivot point B. One of the upper ends of the front cross brace assembly 11 is pivotally connected to the third joint pivot point C, and the second folding linkage mechanism 2 includes: a second seat rod 23, the upper end of the second seat rod 23 and the upper end of the center seat rod 3 are pivotally connected to the two upper ends of the second front cross brace assembly 21 respectively, the lower end of the second seat rod 23 and the lower end of the center seat rod 3 are pivotally connected to the two lower ends of the second rear cross brace assembly 22 respectively, the upper end of the third seat rod 24 and the upper end of the fourth seat rod 25 are pivotally connected to the two upper ends of the second rear cross brace assembly 22 respectively, the lower end of the fourth seat rod 25 is pivotally connected to one of the lower ends of the second front cross brace assembly 21, the first backrest rod 13 and the second backrest rod 14 are of equal length, and the lengths of the first seat rod 15, the center seat rod 3, the second seat rod 23, the third seat rod 24 and the fourth seat rod 25 are equal and less than the lengths of the first backrest rod 13 and the second backrest rod 14.

[0030] The backrest of the first folding linkage mechanism 1 is longer, allowing humans to lean back and rest better when sitting on it. The second folding linkage mechanism 2 is lower than the first folding linkage mechanism 1 and has no backrest structure, making it convenient for pets to get on and off from all directions. In addition, the sitting and lying surface of the second folding linkage mechanism 2 is flat, which is more conducive to pets playing and resting on it.

[0031] refer to Figures 1 to 3In some embodiments, the system further includes a first connecting rod 111, a central connecting rod 4, a second connecting rod 211, a third connecting rod 212, and a fourth connecting rod 213, as well as a first slider 112, a central slider 5, a second slider 214, a third slider 215, and a fourth slider 216. The upper end of the first connecting rod 111 is pivotally connected to the first seat rod 15, and the lower end of the first connecting rod 111 is pivotally connected to the first slider 112, which is slidably connected to the first backrest rod 13. The upper end of the central connecting rod 4 is pivotally connected to the central seat rod 3, and the lower end of the central connecting rod 4 is pivotally connected to the central slider 5, which is slidably connected to the second backrest rod 13. Rod 14; the upper end of the second connecting rod 211 is pivotally connected to the second seat rod 23, the lower end of the second connecting rod 211 is pivotally connected to the second slider 214, and the second slider 214 is slidably connected to the fourth seat rod 25; the upper end of the third connecting rod 212 is pivotally connected to the third seat rod 24, the lower end of the third connecting rod 212 is pivotally connected to the third slider 215, and the third slider 215 is slidably connected to the central seat rod 3; the upper end of the fourth connecting rod 213 is pivotally connected to the fourth seat rod 25, the lower end of the fourth connecting rod 213 is pivotally connected to the fourth slider 216, and the fourth slider 216 is slidably connected to the second seat rod 23.

[0032] Setting up multiple connecting rods and multiple sliders can provide support for the corresponding multiple seat bars and restrict the lateral movement of the corresponding multiple seat bars, making the folding chair more load-bearing, less prone to tilting and collapsing, and at the same time making the folding chair smooth to operate when folding and unfolding, and more compact overall.

[0033] refer to Figures 1 to 3 In some embodiments, a plurality of pivot bases 7 are also included. The plurality of pivot bases 7 are disposed at the lower end of the human-pet shared folding chair that is in contact with the ground, and are used to pivotally connect to the lower end of the first seat post 15, the lower end of the first backrest post 13, the lower end of the second seat post 23, the lower end of the fourth seat post 25, the first joint pivot point A and the second joint pivot point B.

[0034] Understandably, the multiple pivot bases 7 not only provide linkage pivot support, but also ensure that the contact surface between the folding chair and the ground is flat, maintaining the stability of the folding chair during use.

[0035] refer to Figures 1 to 3In some embodiments, multiple pivot members 8 are disposed on the upper part of the human-pet shared folding chair that is not in contact with the ground, for pivotal connection to the upper end of the first front cross support group 11 and the upper end of the first seat post 15 and the upper end of the center seat post 3; the upper end of the first rear cross support group 12 and the upper end of the first backrest post 13 and the upper end of the second backrest post 14; the upper end of the second front cross support group 21 and the upper end of the center seat post 3 and the upper end of the second seat post 23; and the upper end of the second rear cross support group 22 and the upper end of the third seat post 24 and the upper end of the fourth seat post 25.

[0036] Understandably, the multiple pivot members 8 provide connection and linkage pivot support, enabling the folding chair to fold synchronously during the folding process and providing connection and support when the folding chair is unfolded for use.

[0037] refer to Figures 1 to 4 In some embodiments, a seat fabric 9 is also included, which is detachably disposed on the first folding linkage mechanism 1 and the second folding linkage mechanism 2.

[0038] Understandably, the seat fabric 9 can support humans and pets when the folding chair is unfolded, and can also be folded up simultaneously when the folding chair is folded, making it convenient to use and lightweight.

[0039] refer to Figure 4 In some embodiments, a storage bag 91 is provided on the outer side of the first folding linkage mechanism 1. When using the folding chair outdoors, small personal items can be placed in the storage bag 91 to prevent items from being lost while playing.

[0040] refer to Figure 4 In some embodiments, the seat fabric 9 on the first folding linkage mechanism 1 is provided with a neck support 92 for supporting the human neck. When a person leans against the seat fabric 9, the neck is supported, resulting in a better resting experience.

[0041] refer to Figure 4 In some embodiments, the seat fabric 9 is made of Oxford cloth. Since folding chairs are folded multiple times during use, Oxford cloth not only provides good support and softness when folded, but is also durable, reliable, and has a long service life.

[0042] The present invention relates to a folding chair for both humans and pets, which combines a human folding chair and a pet folding bed. When folding, the human and pet parts can be folded simultaneously in one operation. The structure is compact, the folding process is smooth, and it saves time and effort. After folding, it also saves space in use and storage. When unfolded outdoors, the distance between the human and pet is close, making interaction more convenient. It also prevents the pet from shifting or tipping the folding chair, and has strong support rigidity, thus greatly improving the user experience.
