Description

Technical Field

[0001] This utility model relates to the field of hanging basket chair technology, and in particular to a hanging basket chair frame and a hanging basket chair. Background Technology

[0002] In daily life, hanging chairs are widely used due to their portability and comfort. However, existing hanging chairs on the market all have latches on two uprights. When unfolding or folding them up, it is necessary to operate the latches on both uprights in sequence to lock and unlock them. Products with latches on both sides are inconvenient and costly. Therefore, there is an urgent need for a new solution to address these problems. Utility Model Content

[0003] The purpose of this utility model is to provide a hanging basket chair frame and a hanging basket chair to solve the problems existing in the prior art, improve convenience and reduce costs.

[0004] To achieve the above objectives, this utility model provides the following solution:

[0005] This utility model provides a hanging basket chair frame, which has a folded state and an unfolded state, including:

[0006] A linkage mechanism comprising two intersecting links that are hinged at the intersection;

[0007] Two columns are respectively disposed on both sides of the linkage mechanism;

[0008] Folding support legs, with multiple folding support legs movably installed on each of the columns;

[0009] Two sliding members are slidably mounted on the two columns along their respective lengths. Each sliding member is connected to one of the two folding legs. Sliding the sliding member upwards along the column causes the folding leg to extend; sliding the sliding member downwards along the column causes the folding leg to retract. The upper ends of two connecting rods are hinged to the two sliding members; the lower ends of the two connecting rods are hinged to the two columns.

[0010] Two tie rods are hinged together, and the ends of the two tie rods that are far apart from each other are respectively hinged to the upper parts of the two connecting rods.

[0011] Preferably, it further includes a locking member disposed at the hinge of the two pull rods and restricting the relative rotation of the two connecting rods in the extended state.

[0012] Preferably, the two pull rods are a first pull rod and a second pull rod, and the locking member is fixedly connected to the first pull rod. Part of the locking member is located on one side of the second pull rod, and a slot is provided on the locking member located on the side of the second pull rod. The slot opening faces the second pull rod. When the hanging basket chair frame changes from the folded state to the unfolded state, the second pull rod rotates relative to the first pull rod until it enters the slot. The width of the slot opening is smaller than the width of the second pull rod, and at least the structure of the slot opening is made of an elastic material.

[0013] Preferably, the locking element is provided with a handle or a pull ring.

[0014] Preferably, the folding support leg includes two hinged leg rods, with the ends of the two leg rods being hinged to the slider and the bottom of the column, respectively; the hinge joint of the folding support leg in the unfolded state is used for ground support.

[0015] Preferably, the sliding element is a sliding sleeve, which is sleeved on the column.

[0016] Preferably, each of the columns is provided with two retractable legs, and the two retractable legs are symmetrically arranged about the plane in which the two columns are located.

[0017] Preferably, when in the unfolded state, the bottom of the column is suspended.

[0018] The present invention achieves the following technical advantages over the prior art:

[0019] This invention abandons the existing method of setting locks on both uprights, instead using two pull rods on a linkage mechanism. The two pull rods can rotate relative to each other to switch the state of the hanging basket chair frame. When the hanging basket chair frame switches from the folded state to the unfolded state, both linkages rotate downwards, which in turn drives the two pull rods to rotate until the rotation angle of the two pull rods reaches its maximum. At this time, the two pull rods will restrict the further rotation of the two linkages, thus keeping the hanging basket chair frame in the unfolded state even when subjected to downward pressure (when people sit on the hanging basket chair). When folding, the two pull rods can be pulled upwards or the two uprights can be brought together to achieve folding. Therefore, this application improves the convenience of using the hanging basket chair, and the manufacturing process of the pull rods is much simpler than that of the complex locks, thus reducing manufacturing costs.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] This utility model provides a hanging basket chair frame, which has a folded state and an unfolded state, such as Figures 1 to 7As shown, it includes: a linkage mechanism 1, two columns 2, a folding support leg 3, two sliding parts 4, and two tie rods 5.

[0032] The linkage mechanism 1 includes two intersecting links 11 that are hinged at the intersection.

[0033] Two uprights 2 are respectively set on both sides of the linkage mechanism 1. The linkage mechanism 1 is used to connect the uprights 2 on both sides. The uprights 2 are used to support the seat. It can be understood that the above-mentioned folded state and unfolded state can also refer to the folding and unfolding of the seat. Therefore, in the folded state, the two uprights 2 are close together, and in the unfolded state, the two uprights 2 are far apart.

[0034] Each column 2 is equipped with multiple folding legs 3, which are designed to be able to unfold to support the ground or fold to reduce the size.

[0035] Two sliding members 4 are slidably mounted on the two columns 2 along their length. The two sliding members 4 are connected to the two folding legs 3. When the sliding members 4 slide upward along the column 2, they can drive the folding legs 3 to switch to the unfolded state. When the sliding members 4 slide downward along the column 2, they can drive the folding legs 3 to switch to the folded state. The upper ends of the two connecting rods 11 are hinged to the two sliding members 4 respectively. The lower ends of the two connecting rods 11 are hinged to the two columns 2 respectively.

[0036] The two tie rods 5 are hinged together, and the ends of the two tie rods 5 that are far apart from each other are respectively hinged to the upper parts of the two connecting rods 11.

[0037] This utility model abandons the existing technology of setting locks on the two side columns 2 separately. Instead, it sets two pull rods 5 on the linkage mechanism 1. The two pull rods 5 can rotate relative to each other to switch the state of the hanging basket chair frame. When the hanging basket chair frame switches from the folded state to the unfolded state, both connecting rods 11 rotate downwards, thereby driving the two pull rods 5 to rotate until the rotation angle of the two pull rods 5 reaches the maximum. At this time, the two pull rods 5 will restrict the further rotation of the two connecting rods 11, thus keeping the hanging basket chair frame in the unfolded state even when subjected to downward pressure (when people sit on the hanging basket chair). When folding, the two pull rods 5 can be pulled upwards or the two columns 2 can be brought together to achieve folding. Therefore, this application improves the convenience of using the hanging basket chair, and the manufacturing process of the pull rods 5 is much simpler than that of the complex locks, thus reducing the manufacturing cost.

[0038] In some embodiments, the present invention further includes a locking member 6, which is disposed at the hinge of the two pull rods 5 and restricts the relative rotation of the two connecting rods 11 in the extended state.

[0039] This embodiment is designed to prevent the suspended basket chair frame from becoming unstable and prone to folding upwards when moved in its unfolded state. Therefore, a locking member 6 is used to fix the relative position of the two connecting rods 11 in the unfolded state, thereby stabilizing the suspended basket chair frame in the unfolded state.

[0040] The locking component 6 can specifically adopt the following structure. For ease of understanding, the two pull rods 5 are defined as the first pull rod 51 and the second pull rod 52, respectively. The locking component 6 is fixedly connected to the first pull rod 51, and part of the locking component 6 is located on one side of the second pull rod 52. The locking component 6 located on one side of the second pull rod 52 is provided with a slot, and the slot opening faces the second pull rod 52. When the hanging basket chair frame changes from the folded state to the unfolded state, the second pull rod 52 rotates relative to the first pull rod 51 until it enters the slot. The width of the slot opening is smaller than the width of the second pull rod 52. At least the structure of the slot opening is made of an elastic material, such as plastic, metal, etc.

[0041] In this embodiment, by setting a slot and making the width of the slot opening smaller than the width of the second pull rod 52, the second pull rod 52 can be inserted into the slot when rotated relative to the first pull rod 51 to the unfolded state. The width of the slot opening is smaller than the width of the second pull rod 52, which restricts the second pull rod 52 to prevent it from easily moving out of the slot. Since the structure at the opening is elastic, when the hanging basket chair frame needs to be folded, the locking member 6 can be manually pulled upward to move the second pull rod 52 out of the slot, thereby unlocking it. Compared with the prior art solution of setting a buckle or pin on the column 2, the unlocking process in this embodiment is simple and easy.

[0042] In some embodiments, the locking member 6 is provided with a handle or pull ring 7.

[0043] This embodiment makes it more convenient for users to unlock the device by hand using the locking element 6.

[0044] In some embodiments, the folding support leg 3 includes two hinged leg rods 31, with the ends of the two leg rods 31 that are far apart being hinged to the slider 4 and the bottom of the column 2, respectively; the hinge joint of the folding support leg 3 in the unfolded state is used to support the ground.

[0045] In this embodiment, when the slider 4 slides down the column 2, it drives the two legs 31 in the folding support leg 3 to rotate relative to each other and cause the hinge joint to move downward.

[0046] In some embodiments, the slider 4 is a sliding sleeve, which is fitted onto the column 2.

[0047] The sliding connection method in this embodiment, which is fitted onto the column 2, is more stable than other sliding connection methods.

[0048] In some embodiments, each column 2 is provided with two folding legs 3, which are symmetrically arranged about the plane containing the two columns 2. Of course, in other embodiments, three or four folding legs 3 can also be provided on one column 2, which increases the volume of the device, but also enhances the stability in the unfolded state.

[0049] In some embodiments, when in the unfolded state, the bottom of the column 2 is suspended.

[0050] Compared to the existing technology where the bottom of the column 2 also rests on the ground, this embodiment of the utility model reduces the length of the column 2, which reduces the height after folding and thus reduces the volume after folding.

[0051] This utility model embodiment also provides a hanging basket chair, including the hanging basket chair frame and chair seat as described above.

[0052] This utility model embodiment possesses all the advantages of the above-described hanging basket chair frame embodiment, and will not be repeated here.

[0053] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
