Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of elderly assistance machinery, and particularly to a folding lift chair. Background Art
[0002] Due to the decline of physical functions, some elderly people are unable to stand up again by their own strength after falling. If the elderly cannot get up for a long time after falling, more serious consequences may occur. To solve the problem of being unable to stand up after falling, the existing solution is to provide a lift chair that can help the elderly stand up. However, the existing lift chair has a large volume after being stored, which not only occupies a large storage space but also is not convenient for transportation and use, and is laborious to carry; and the bottom support structure of the lift chair is a detachable structure, which requires disassembling parts for assembly, and the overall stability is not good. It is easy to shake during actual use, and the fragmented parts are also likely to cause some parts to be lost, affecting normal use. Utility Model Content

[0027] To make the objectives, features, and advantages of the present disclosure more obvious and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present disclosure.
[0028] The embodiments of the present disclosure will be described in detail below with reference to the drawings.
[0029] Referring to Figures 1 to 3 As shown, a folding and lifting chair according to an exemplary embodiment of the present disclosure includes a support mechanism, a backrest assembly 4, a seat assembly 5, and a lifting mechanism 6. The support mechanism includes a base assembly 1, a support member 2, and a fixed frame 3. The base assembly 1 is flexibly connected to the support member 2. The base assembly 1 has a support state and a storage state. The base assembly 1 is configured to be able to rotate relative to the support member 2 or slide along the length direction of the support member 2, so that the base assembly 1 can be switched between the support state and the storage state. The fixed frame 3 is fixed through the support member 2. The backrest assembly 4 is slidably connected to the fixed frame 3. The seat assembly 5 is rotatably connected to the bottom of the backrest assembly 4. The lifting mechanism 6 is fixed to the fixed frame 3. The lifting mechanism 6 is connected to the backrest assembly 4 and is used to drive the backrest assembly 4 to drive the seat assembly 5 to move along the length direction of the fixed frame 3.
[0030] In this embodiment, the lifting mechanism 6 drives the backrest assembly 4 to drive the stool assembly 5 to move up and down on the fixed frame 3. It can be understood that the front, back, left, right, up and down directions in the present disclosure are based on the directions of the folding lift chair when it is normally used. For example, the stool assembly 5 is arranged in front of the backrest assembly 4 to provide a seat for the user; the fixed frame 3 is arranged in the vertical direction, and the stool assembly 5 moves up and down along the length direction of the fixed frame 3, that is, the stool assembly 5 slides in the vertical direction to change its height relative to the ground; the length direction of the support member 2 extends along the front and back direction of the folding lift chair. The fixed frame 3 is made of a rigid material, which is rated to withstand the applied force without bending or incurring other damage. An important aspect of the fixed frame 3 is its sturdiness. In particular, when the elderly sit on the stool assembly 5, the stool assembly 5 and the fixed frame 3 are subjected to a large force. For the comfort and safety of the elderly, the fixed frame 3 can be a sufficiently strong steel pipe so that its deformation is kept to a minimum or zero. The bench assembly 5 can be lowered to the ground in the vertical direction to provide more convenience to the elderly who are in a state of mobility difficulties. At the same time, in order to give the elderly more autonomy to choose, the bench assembly 5 needs to be able to rise to a maximum height to expand the scope of application. Therefore, the range of travel of the bench assembly 5 can be set at 0 to 500 mm while the bench assembly 5 remains horizontal. The lifting mechanism 6 can efficiently achieve different starting heights of the bench assembly 5. At the same time, the bench assembly 5 is rotatably connected to the backrest assembly 4 so that the bench assembly 5 can be folded and provided for sitting. The support mechanism cooperates with the overall support of the folding lifting chair so that the bench assembly 5 can always withstand the support force from the support mechanism, thereby assisting the elderly to change from a lying posture to a sitting or standing posture during the lifting process. Since the support mechanism of the folding lift chair includes a base assembly 1 and a support member 2 flexibly connected to the base assembly 1, the flexible connection here mainly includes a spring connection, a flexible shaft connection, a moving connection, a sliding connection, a rolling connection and a rotating connection, etc. Specifically, the base assembly 1 is configured to be able to rotate relative to the support member 2 or slide along the length direction of the support member 2, so that the base assembly 1 can be converted between a supporting state and a storage state. After the base assembly 1 rotates or slides, the space occupied by the base assembly 1 in the lateral direction becomes smaller, so that the base assembly 1 is changed to a storage state, so that the bottom of the folding lift chair can be stored inward after use and folded into a flat shape, which greatly improves the utilization rate of the space, does not need to disassemble some parts for separate storage, solves the problem of easy loss of parts, is simple to operate during use and storage, and is convenient for transportation; and this structure has better integrity, improves the stability of the overall structure when the folding lift chair is unfolded, and can give users a better sense of security.
[0031] Reference Figure 4 and Figure 5As shown, in an implementable embodiment, the base assembly 1 includes a first floor foot 11 and a second floor foot 12, and the support member 2 includes a first guide rail 22 and a second guide rail 23 that is collinear with the first guide rail 22. The first floor foot 11 is disposed within the first guide rail 22, and the second floor foot 12 is slidably connected to the second guide rail 23 and can slide along the second guide rail 23.
[0032] In this embodiment, the first floor foot 11 is located in front of the fixed frame 3, and the second floor foot 12 is located behind the fixed frame 3. The first floor foot 11 and the second floor foot 12 cooperate with the fixed frame 3 to support the entire folding and lifting chair. The first floor foot 11 and the second floor foot 12 can be made of hollow square tubes of iron, steel, or aluminum alloy to bear the weight of the folding and lifting chair and ensure stability during the lifting process. The first guide rail 22 is provided with a first cover plate 223. The first guide rail 22 is formed into a slideway by the first cover plate 223, which limits the first floor foot 11 within the slideway and allows it to slide along it. Sliding pieces 8 are provided both above and below the connection of the first floor foot 11 to the first guide rail 22. The sliding pieces 8 are made of polyoxymethylene (abbreviated as POM). The POM material has excellent mechanical properties, wear resistance, chemical resistance, low water absorption, heat resistance, and weather resistance, etc., which can reduce the wear caused by the relative movement between the first floor foot 11 and the first guide rail 22. The second guide rail 23 is provided with a second cover plate 232. The second guide rail is formed into a slideway by the second cover plate 232, which limits the second floor foot 12 within the slideway and allows it to slide along it. Sliding pieces 8 are also provided both above and below the connection of the second floor foot 12 to the second guide rail 23. The sliding pieces 8 have the same structure and material as the sliding pieces 8 provided on the first floor foot 11, and thus will not be elaborated here.
[0033] In an implementable embodiment, the first floor foot 11 is equipped with a spring buckle 7, and a first limit hole 221 is formed on the first guide rail 22. The first limit hole 221 is located at one end of the first guide rail 22 close to the fixed frame 3. The spring buckle 7 cooperates with the first limit hole 221 to limit the first floor foot 11 in the first position.
[0034] In this embodiment, the spring buckle 7 is a V-shaped spring buckle 7, and the V-shaped spring buckle 7 is installed inside the square tube of the first floor footing 11. The V-shaped spring buckle 7 is composed of a spring piece and a buckle part. The spring piece provides elasticity, and the buckle part is used to pass through the square tube and cooperate with the first limiting hole 221 on the first guide rail 22. The first position of the first floor footing 11 is the position when the V-shaped spring buckle 7 is engaged with the first limiting hole 221 and the first floor footing 11 is limited in the slideway by the first cover plate 223. A second limiting hole 231 is opened at one end of the second guide rail 23 close to the fixed frame 3. A V-shaped spring buckle 7 is also installed inside the square tube of the second floor footing 12. The buckle part of the V-shaped spring buckle 7 passes through the square tube of the second floor footing 12 and cooperates with the second limiting hole 231 on the second guide rail 23. When adjusting the second floor footing 12, press the buckle part to make it contract under force into the square tube of the second floor footing 12 to release the limit, and then push the second floor footing 12 along the second guide rail 23 into the inside of the support member 2 to complete the contraction of the second floor footing 12.
[0035] Referring to Figure 8 As shown, in an implementable embodiment, a shaft hole 222 is further opened on the first guide rail 22. The shaft hole 222 is located at one end of the first guide rail 22 far from the fixed frame 3. The spring buckle 7 is configured to be able to be snapped into the shaft hole 222 from the first limiting hole 221 when subjected to an external force and to be able to rotate in the shaft hole 222.
[0036] In this embodiment, when adjusting the first floor footing 11, press the buckle part to make it contract under force into the square tube of the first floor footing 11 to release the limit, and then pull the first floor footing 11 or the buckle part of the V-shaped spring buckle automatically snaps into the shaft hole 222. There is no first cover plate 223 above the shaft hole 222. That is, when the first floor footing 11 moves from the first position to the V-shaped spring buckle 7 is snapped into the rotating shaft, the first floor footing 11 is no longer limited by the first cover plate 223. At this time, the first floor footing 11 can rotate around the axis of the shaft hole 222, and the first floor footing 11 flips upward and abuts against the fixed frame 3 to complete the folding of the first floor footing 11. When the first floor footing 11 flips upward and abuts against the fixed frame 3, and at the same time the second floor footing 12 is pushed along the second guide rail 23 into the inside of the support member 2, the base assembly 1 is in a stored state and the storage is completed.
[0037] Specifically, in an implementable embodiment, when the base assembly 1 is in a supporting state, the first floor footing 11 and the second floor footing 12 are on the same straight line; when the base assembly 1 is converted from the supporting state to the stored state, the first floor footing 11 rotates around the shaft hole 222 and fits against the fixed frame 3, and the second floor footing 12 contracts along the support member 2 in the direction close to the fixed frame 3.
[0038] In this embodiment, when the base assembly 1 is converted from the supporting state to the storage state, press the V-shaped spring buckle 7 at the first limiting hole 221 to move the first base foot 11 from the first position until the V-shaped spring buckle 7 is snapped into the rotating shaft, and then flip the first base foot 11 upward; press the V-shaped spring buckle 7 at the second limiting hole 231 and push the second base foot 12 into the support member 2, thereby completing the folding and storage of the base assembly 1. When the base assembly 1 is converted from the storage state to the supporting state, flip the first base foot 11 downward, and then press the V-shaped spring buckle 7 to snap it into the first limiting hole 221; pull the second base foot 12 out along the second guide rail 23, thereby completing the unfolding of the base assembly 1.
[0039] Referring to Figure 7 As shown, in an implementable embodiment, the backrest assembly 4 includes a backrest frame 41, a cushion 42 mounted on the backrest frame 41, and connecting shafts 43 provided on both sides of the backrest frame 41. An armrest 9 is rotatably connected to the connecting shaft 43. Among them, a magnetic member 10 is mounted on the armrest 9. When the base assembly 1 is in the storage state, one end of the first base foot 11 away from the shaft hole 222 is magnetically attracted to the magnetic member 10.
[0040] In this embodiment, the elderly can support their bodies on the armrest 9 and position themselves on the seat assembly 5. Therefore, the armrest 9 itself needs to be strong enough to support the weight of the elderly. In particular, the armrest 9 will not rotate and sag when a force is applied by the elderly. The armrest 9 has a support position and a retracted position on the path of rotating along the connecting shaft 43. The support position generally corresponds to the position when the armrest 9 is parallel to the seat assembly 5 when it is unfolded, and the retracted position corresponds to the position when the armrest 9 is parallel to the fixed frame 3. Since the magnetic member 10 is mounted on the armrest 9, the magnetic member 10 can be located on the side facing when the armrest 9 is in the retracted position, so that the first base foot 11 is magnetically attracted by the magnetic member 10 after being flipped upward by a certain angle, enhancing the fixing effect during storage.
[0041] In an implementable embodiment, the seat assembly 5 includes a seat frame 51 and a seat cushion 52 mounted on the seat frame 51. The seat frame 51 is rotatably connected to the backrest frame 41 through a pivot 53. Among them, the seat assembly 5 has an unfolded state and a folded state. When the seat assembly 5 is converted between the unfolded state and the folded state, the seat frame 51 rotates relative to the backrest frame 41 around the pivot 53 in a direction close to or away from the cushion 42.
[0042] In this embodiment, when the seat assembly 5 is converted from the unfolded state to the folded state, the seat frame 51 rotates around the pivot 53, driving the seat cushion 52 to approach the backrest cushion 42 until the entire seat cushion 52 is close to the backrest cushion 42. It should be noted that the upper surface of the seat cushion 52 is preferably in close contact with the front surface of the backrest cushion 42. The "close contact" here is to highlight the compact structure of the folding lift chair after storage. For example, the gap between the two objects in close contact can be limited to less than 8 mm, and the gap is preferably less than 5 mm or 2 mm. The seat cushion 52 can be made of a flexible material or synthetic polymer such as fabric, leather, or rubber.
[0043] In an implementable embodiment, the lifting mechanism 6 includes a lifting motor 61 fixedly arranged on the fixed frame 3. The backrest frame 41 is connected to the output end of the lifting shaft 62 of the lifting motor 61, and the backrest frame 41 can move along the lifting shaft 62.
[0044] In this embodiment, the lifting motor 61 can be electrically connected to a control mechanism (not shown in the figure) through wires to control the lifting and speed of the lifting motor 61. The lifting mechanism 6 will drive the backrest assembly 4 and the seat assembly to move upward along the lifting shaft 62. In the initial position, the seat assembly 5 is generally in a horizontal state, close to or in contact with the ground. At this time, the seat assembly 5 is in the unfolded state, which can assist the elderly to sit on the seat assembly 5 when they fall to the ground. After the elderly sit on the seat assembly 5, by pressing the control mechanism, as the backrest frame 41 moves further upward, the seat assembly 5 will also move upward accordingly until the elderly on the seat assembly 5 are in a reasonable position, and then press the control mechanism to make the lifting motor 61 stop working. It should be noted that during the above movement process, the working state of the lifting motor 61 is controlled by the control mechanism, and the control mechanism presets information such as the working state and working time. The control mechanism controls the telescopic amount of the lifting motor 61, which belongs to the prior art and will not be elaborated here. In addition, since the telescopic movement of the lifting motor 61 has a more efficient reciprocating movement compared to the lead screw mechanism, it can be adjusted more quickly, providing a better user experience for the user. Of course, the specific adjustment parameters can be set according to the actual requirements of assisting the user to stand, and the telescopic speed of the lifting motor 61 can be set to achieve a better experience, which will not be elaborated here.
[0045] Refer to Figure 6 As shown, in an implementable embodiment, a roller 121 is installed at one end of the second floor foot 12 away from the second guide rail 23.
[0046] In this embodiment, when the second floor foot 12 retracts into the support member 2, the roller 121 on the second floor foot 12 still protrudes outside the support member 2, which is convenient for handling. During the actual handling process, turn the folded folding lift chair backward by a certain angle, and the roller 121 on the second floor foot 12 can be used for towing.
[0047] In an implementable embodiment, the support member 2 further includes a first jack 21 and a second jack 24. The fixed frame 3 includes a vertical rod 31 and a bottom cross bar 32. The vertical rod 31 is tightly connected to the first jack 21, and the bottom cross bar 32 is tightly connected to the second jack 24.
[0048] In this embodiment, the bottom of the lifting motor 61 is fixed to the bottom cross bar 32. The bottom cross bar 32 and the second jacks 24 of the support members 2 on both sides are fixed by screws, and the vertical rod 31 and the first jack 21 are fixed by screwing in screws.
[0049] In the description of the present disclosure, it should be understood that the orientation or positional relationship indicated by the orientation words is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present disclosure and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present disclosure; the orientation words "inside" and "outside" refer to the inside and outside relative to the contour of each component itself.
