Description

Technical Field

[0001] The utility model relates to the technical field of folding chairs, in particular to a hanging folding chair. Background Art

[0002] A hanging folding chair generally includes a mounting portion that is mounted on a wall or other fixed object with a mounting surface. The chair's support and seat are foldable relative to the mounting portion. When the chair is folded, the support and seat rotate upward and toward the mounting portion, lifting them off the ground. The chair then hangs from the wall or fixed object solely by the mounting portion, overcoming gravity. When the chair is unfolded, the support and seat rotate downward and away from the mounting portion, with the bottom of the support resting on the ground. The chair then relies on the mounting and support portions for stability. When a user sits on the chair, the support is rigidly supported on the ground or other fixed object, creating indirect, rigid contact between the user and the ground, resulting in poor seating comfort. Furthermore, as the chair unfolds from its folded position to near-fully unfolded, the bottom of the support gradually contacts the ground. Due to the acceleration of gravity, the bottom of the support strikes the ground at a certain speed. This impact generates a loud noise and also causes significant impact force on the support, making it susceptible to damage, hindering the chair's use. Summary of the Invention

[0003] The purpose of the utility model is to provide a hanging folding chair, which forms an elastic buffer between the user and a fixed object such as the ground by arranging a buffer structure at the bottom end of the support part, thereby improving the user's sitting comfort, reducing the impact noise caused by the support part descending, and extending the service life of the folding chair.

[0004] To achieve the above-mentioned purpose, the technical solution of the present invention is: a hanging folding chair, comprising a support part, a seat part and a mounting part, the seat part is hinged to the mounting part, the support part is hinged to the seat part, the mounting part is used for installation and fixation so that the folding chair is hung and installed, the end of the support part hinged to the seat part is defined as the top end, and the other end opposite to it is defined as the bottom end, the bottom end of the support part is provided with a buffer structure, the buffer structure is used to buffer the impact of the bottom end of the support part, and the support part is used to indirectly support on a fixed object with the help of the buffer structure.

[0005] In one embodiment, the bottom end of the support portion is defined as downward relative to the top end, and a buffer cavity is provided at the bottom end of the support portion, and the buffer cavity has a buffer mounting opening facing downward, and the buffer structure includes an elastic member and a buffer member, and the buffer member is slidably installed in the buffer cavity and a part of it protrudes from the buffer mounting opening of the buffer cavity, so that the support portion is indirectly supported on a fixed object with the aid of the buffer member of the buffer structure, and the two ends of the elastic member respectively abut against the buffer member and the inner wall of the buffer cavity.

[0006] In one embodiment, the buffer member is provided with an elastic limiting hole, a portion of the elastic member is disposed in the elastic limiting hole, and another portion protrudes from the buffer member and abuts against the inner wall of the buffer cavity.

[0007] In one embodiment, the elastic member is a spring.

[0008] In one embodiment, the buffer component includes a buffer block and a foot pad arranged below the buffer block, the buffer block is made of a hard material, the foot pad is made of an elastic material, and the support portion is used to indirectly support the fixed object with the help of the foot pad of the buffer component.

[0009] In one embodiment, the buffer block is provided with a foot pad installation cavity and an exhaust hole, and the exhaust hole is connected to the foot pad installation cavity to balance the air pressure inside and outside the foot pad installation cavity.

[0010] In one embodiment, the inner wall of the buffer cavity is provided with a first limiting structure, and the buffer component is provided with a second limiting structure. The first limiting structure and the second limiting structure cooperate to form a limit for the downward movement of the buffer component to prevent the buffer component from falling off from the buffer cavity.

[0011] In one embodiment, the first limiting structure is a limiting protrusion, and the limiting protrusion is provided with a first limiting surface facing upward. The second limiting structure is a buckle, and the buckle is provided with a second limiting surface facing downward. The first limiting surface and the second limiting surface abut and cooperate to form the movement limit of the buffer.

[0012] In one embodiment, a mounting groove is formed at the bottom end of the support portion, and a mounting cover is provided on one side of the support portion. The mounting cover is arranged on the mounting groove and encloses the side wall of the mounting groove to form the buffer cavity.

[0013] In one embodiment, the folding chair is adapted to be mounted on a bathroom wall.

[0014] The beneficial effects of the present invention are as follows: the present invention provides a buffer structure at the bottom of the support portion to buffer the force between the support portion and a fixed object such as the ground, so that a flexible contact is formed between the support portion and the fixed object such as the ground. When the user sits down, the buffer structure can reduce the force directly exerted by the ground on the support portion, thereby improving the comfort of sitting. The buffer structure can also buffer the impact force of the support portion hitting the ground during the unfolding process, thereby preventing the generation of impact noise. It can also reduce the force exerted on the support portion, thereby preventing the folding chair from being damaged due to frequent impacts, thereby improving the service life of the folding chair. In the buffer structure composed of the buffer block, the foot pad and the elastic member, the elastic member can withstand large impacts and form a preliminary buffer. The foot pad made of elastic material can provide a smaller buffer, thereby further improving the buffer performance of the buffer structure. The hard buffer block can give the buffer structure a certain rigidity, thereby preventing insufficient buffer performance due to the buffer structure being too soft. That is, the buffer block, the foot pad and the elastic member cooperate to ensure that the buffer structure has sufficient buffer performance, thereby preventing the bottom end of the support portion from directly contacting the ground.

DETAILED DESCRIPTION

[0021] To further illustrate various embodiments, the present invention is provided with accompanying drawings. These drawings form part of the disclosure of this invention and are primarily used to illustrate the embodiments and, in conjunction with the relevant description in the specification, to explain the operating principles of the embodiments. By referring to these drawings, those skilled in the art will understand other possible implementations and the advantages of this invention. The components in the figures are not drawn to scale, and similar reference numerals are generally used to represent similar components.

[0022] See Figures 1 to 3 As shown, the utility model discloses a hanging folding chair, comprising a support portion 1, a seat portion 2, and a mounting portion 3. The seat portion 2 is hingedly connected to the mounting portion 3, and the support portion 1 is hingedly connected to the seat portion 2. The mounting portion 3 is used to mount and secure the folding chair so that it can be hung. Taking a bathroom chair hung on a bathroom wall as an example, the mounting portion 3 is mounted and fixed to the wall, and the support portion 1 and the seat portion 2 are foldably connected, so that the bathroom chair is a folding chair. Figure 2 The figure shows the bathroom chair in the unfolded state. The end of the support part 1 hinged to the seat part 2 is defined as the top end, and the other end opposite thereto is defined as the bottom end. The bottom end of the support part 1 is supported on the ground, thereby cooperating with the mounting part 3 to maintain the stability of the bathroom chair as a whole. Figure 5 The figure shows the bathroom chair in the folded state. The bottom end of the support portion 1 is defined as downward relative to the top end, and the direction opposite thereto is defined as upward. The seat portion 2 is flipped upward, and the support portion 1 also moves upward. The bathroom chair is hung on the wall by the mounting portion 3.

[0023] The bottom end of the support portion 1 is provided with a buffer structure 4, which is used to cushion the impact on the bottom end of the support portion 1. The support portion 1 is indirectly supported on the ground by means of the buffer structure 4. By providing the buffer structure 4 at the bottom of the support portion 1, the present invention cushions the force between the support portion 1 and a fixed object such as the ground, thereby forming a flexible contact between the support portion 1 and the fixed object such as the ground. When the user sits down, the buffer structure 4 can absorb the force directly acting on the support portion 1 from the ground, thereby improving the sitting comfort. When the user sits on the folding chair, the force applied by the user to the seat portion 2 changes and is transmitted along the support portion 1 to the buffer structure 4. The buffer structure 4 can thus deform, further improving the user comfort of the folding chair. In addition, the buffer structure 4 can also cushion the impact force of the support portion 1 hitting the ground during the unfolding process, preventing the generation of impact noise, reducing the impact force on the support portion 1, preventing damage to the folding chair due to frequent impacts, and increasing the service life of the folding chair.

[0024] See Figure 4 and Figure 5As shown, a buffer cavity 10 is provided at the bottom end of the support portion 1. The buffer cavity 10 has a buffer installation opening facing downward. The buffer structure 4 includes an elastic member 41 and a buffer member 42. The buffer member 42 is slidably mounted in the buffer cavity 10, and a portion thereof protrudes from the buffer installation opening of the buffer cavity 10. Thus, the support portion 1 is indirectly supported on the ground by means of the buffer member 42 of the buffer structure 4. The two ends of the elastic member 42 respectively abut against the buffer member 42 and the inner wall of the buffer cavity 10. Through the cooperation of the elastic member 41 and the buffer member 42, the buffer member 42 abuts against the ground, transmitting the impact force between the buffer member 42 and the ground to the elastic member 41. The elastic member 41 deforms to absorb the impact force, thereby achieving the purpose of buffering, improving the user's sitting comfort, and reducing the force on the support portion 1, especially the various connections of the bathroom chair.

[0025] The buffer member 42 is provided with an elastic limiting hole 4211, a portion of the elastic member 41 is arranged in the elastic limiting hole 4211, and the other portion protrudes from the buffer member 42 and rests against the inner wall of the buffer cavity 10. The presence of the elastic limiting hole 4211 can limit the deformation direction of the elastic member 41, so that the direction of the elastic force of the elastic member 41 is closer to the direction of the impact force received by the buffer member 42, thereby improving the buffering effect. The elastic member 41 of this embodiment is a coil spring. The deformation amplitude of the coil spring is large and can better play a buffering effect. In addition, in order to further limit the deformation direction of the coil spring, the inner wall of the buffer cavity 10 of the support part 1 is also provided with a limiting protrusion 11. The end of the coil spring is sleeved outside the limiting protrusion 11, and the limiting protrusion 11 forms a limit for the coil spring. In other embodiments, the elastic member can also be a compression spring sheet or an elastic silicone rod.

[0026] The cushioning member 42 includes a buffer block 421 and a foot pad 422 disposed below the buffer block 421. The buffer block 422 is made of a hard material, specifically plastic or metal, while the foot pad 422 is made of an elastic material, specifically rubber or silicone. The support portion 1 is indirectly supported on the ground by the foot pad 422 of the cushioning member 42. The foot pad 422, made of elastic material, has a certain degree of deformation and can absorb a certain amount of shock. The foot pad 422 works together with the elastic member 41 to further enhance the cushioning effect of the cushioning structure and further reduce the collision noise between the buffer member 42 and the ground. The foot pad 422 also provides a certain anti-slip effect, making the bathroom chair more stable.

[0027] To ensure a more secure connection between foot pad 422 and buffer block 421, foot pad 422 is installed in foot pad mounting cavity 4212 of buffer block 421 with an interference fit, forming a relatively closed cavity. This can make foot pad 422 difficult to install in cavity 4212, resulting in unstable installation or difficulty in removing it. To overcome the difficulty of installing or removing foot pad 422, buffer block 421 is provided with a vent hole 4213. Vent hole 4213 communicates with cavity 4212 to balance the air pressure inside and outside cavity 4212. In this embodiment, vent hole 4213 is located at the top of cavity 4212, connecting it to elastic stopper hole 4211. In other embodiments, vent hole 4213 can also be located on the side of cavity 4212.

[0028] Since the buffer installation opening of the buffer cavity 10 is downwardly facing, in order to prevent the buffer member 42 from leaving the buffer cavity 10 and falling under the action of gravity, a first limiting structure 12 is provided on the inner wall of the buffer cavity 10, and a second limiting structure 4214 is provided on the buffer block 421 of the buffer member 42. The first limiting structure 42 and the second limiting structure 4214 cooperate to form a limit for the downward movement of the buffer member 42, thereby preventing the buffer member 42 from falling out of the buffer cavity 10. More specifically, the first limiting structure 12 of this embodiment is a limiting protrusion, which is provided with a first limiting surface facing upward, and the second limiting structure 4214 is a buckle, which is provided with a second limiting surface facing downward. The first limiting surface and the second limiting surface abut and cooperate to form a movement limit for the buffer member 42. In other embodiments, the first limiting structure can be a snap-in hole opened on the side of the buffer cavity 10, and the second limiting structure can be a snap-in protrusion arranged on the side of the buffer block 421. The snap-in protrusion is snapped into the snap-in hole to form a snap-in fit between the buffer part 42 and the support part 1 to prevent the buffer part 42 from falling.

[0029] To facilitate installation of the buffer structure and the injection molding of the first limiting structure 12 within the buffer cavity 10, a mounting cover 5 is provided on one side of the support portion 1 for engagement. A mounting slot is defined at the bottom end of the support portion 1. The mounting cover 5 is positioned within the slot and, together with the sidewalls of the slot, forms the buffer cavity 10. The presence of the mounting cover 5 allows the buffer cavity 10, which is open only at the bottom, to also have side openings, facilitating installation of the buffer structure 4 and simplifying the injection molding of the support portion 1.

[0030] For a hanging folding chair, the installation height of the installation part 3 will affect the support of the bottom end of the support part 1. When the bottom end of the support part 1 is difficult to support the ground due to the installation height being too high or cannot be fully opened due to the installation height being too low, the buffer structure 4 can compensate for the deficiency of the folding chair caused by inaccurate installation height through the deformation of its elastic part 41, and can also compensate for the deficiency of unstable support of the folding chair caused by the uneven ground.

[0031] In addition to bathroom chairs, the folding chair of the present invention can also be used for other functions, such as a shoe-changing chair fixedly installed at a porch, etc., which can be fixed but not often used. In addition, the fixed object supported by the bottom end of the support portion 1 is not limited to the ground, but can also be other fixed objects.

[0032] Although the present invention is specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that the remaining undescribed parts are prior art, and that various changes made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined by the appended claims fall within the scope of protection of the present invention.
