Description

Technical Field

[0001] The invention belongs to the technical field of bathing assistance, and in particular relates to a split-and-combination bathing assistance device. Background Art

[0002] Bathing assistance is a service for the elderly. Bathing assistants carry professional bathing assistance equipment and provide a complete set of bathing assistance services to the elderly in need. Bathing assistants mainly serve the elderly and disabled people, providing deep cleaning effects.

[0003] At present, bathing assistance equipment generally includes a bathing assistance bathtub and a transfer cart (or bathing assistance chair). The bathing assistance bathtub can be flipped and unfolded to form a bathing entrance, and then the transfer cart is pushed in from the bathing entrance and the bathtub door is closed, so that the elderly and disabled people can bathe in the bathtub and sit on the transfer cart.

[0004] However, the existing bathing assistance process has the following technical defects:

[0005] 1) Ordinary transfer vehicles cannot separate the seat and the walking chassis. Therefore, the whole vehicle takes up a large space after entering the bathtub, and the center of gravity is high. If you want to take a bath, the required bathtub is larger and more bath liquid is required. In addition, the walking chassis will also cause bath liquid contamination, resulting in a poor bathing service experience and difficult operation for the bathing assistant;

[0006] 2) The overall mobility is not convenient enough to meet the needs of door-to-door service, resulting in low practicality;

[0007] 3) The required sitting or lying posture adjustment cannot be formed during bathing, which further increases the difficulty for the bathing assistant and also greatly reduces the comfort of bathing. Summary of the invention

[0008] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an improved split-and-combination type bathing aid device.

[0009] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0010] A split-and-combined bathing aid device comprises a bathing aid bathtub and a transfer vehicle.

[0011] The bathing-assisting bathtub comprises a cylinder body, a door which is formed from the end of the cylinder body and can be flipped sideways to open or close, and a movable chassis of the cylinder body, wherein after the door is opened, the open end of the cylinder body forms a bathing port;

[0012] The transfer vehicle comprises a bathing-assisting seat and a walking chassis, wherein the bathing-assisting seat comprises a chair body, a cushion portion, a backrest portion and a leg support portion formed on the chair body and relatively rotatably connected, the cushion portion, the backrest portion and the leg support portion are adjusted relative to the chair body to change the user's sitting and lying posture on the bathing-assisting seat; the walking chassis is separately assembled with the bottom of the bathing-assisting seat through a self-locking component;

[0013] The bathing-assisting equipment also includes a positioning device for docking the shifting vehicle with the cylinder body, the positioning device includes a docking part and an alignment part, wherein when taking a bath, the cylinder body triggers the self-locking component to unlock, the bathing-assisting seat and the walking chassis are separate, and the docking part guides the bathing-assisting seat to the cylinder body; the alignment part interlocks the walking chassis with the bottom of the cylinder body based on the synchronous linkage formed by unlocking; when getting out of a bath, the bathing-assisting seat withdraws from the docking part, the self-locking component resets to form self-locking, and the alignment part unlocks the walking chassis and the bottom of the cylinder body relatively based on the synchronous linkage formed by self-locking, and the bathing-assisting seat and the walking chassis are combined.

[0014] Preferably, the self-locking component includes a lock seat mounted on the walking chassis, a lock head that is arranged at the bottom of the bathing seat and cooperates with the lock seat through a torsion spring, and an active lock hook that keeps the lock head moving, wherein the lock head is pressed against the lock seat by the force provided by the torsion spring and the active lock hook to form a self-locking. Here, the movement of the active lock hook is not only linked with the movement of the combined and separated parts, so as to further improve the stability and safety of the self-locking of the lock head and the lock seat, but also can further enhance the self-locking performance of the lock head and the lock seat based on the hooking.

[0015] Furthermore, the lock seat includes a seat body having a platform portion and a slope foot portion, and when self-locking is formed, the lock head abuts against the junction of the platform portion and the slope foot portion, and the relative movement of the lock head is limited based on the blocking formed by the slope foot portion and the torsion force of the torsion spring itself.

[0016] According to a specific implementation and preferred aspect of the present invention, a positioning seat and a tension spring are also provided on the walking chassis, and a movable locking hook is slidably arranged on the walking chassis along the length direction of the seat body. The two ends of the tension spring are respectively installed on the positioning seat and the movable locking hook to maintain the tensioning hooking trend to form self-locking of the lock head and the lock seat.

[0017] Preferably, a trigger unlocking module is formed at the bottom of the cylinder body, wherein when separated, the trigger unlocking module resists and forces the movable lock hook to disengage from the lock head, at which time the lock head loses the restriction of the movable lock hook and is triggered by the cylinder body to unlock relative to the lock seat.

[0018] In some specific embodiments, the alignment part includes a first matching part fixedly mounted on the bottom of the cylinder body, and a second matching part mounted on the bathing seat through a torsion spring, wherein the second matching part is linked with the lock head, and when the lock head is separated from the second matching part, the lock head and the lock seat are unlocked, and the second matching part is reset and docked and interlocked with the first matching part. Preferably, one of the first matching part and the second matching part is a lock hook, and the other is a locking module in the shape of a hook, a block or a rod. The hooking method makes the docking of the two more stable.

[0019] According to another specific implementation and preferred aspect of the present invention, a pressure rod is further provided on the lock, wherein the pressure rod can be pressed on the second matching portion to form a linkage, and when the pressure rod is disengaged from the second matching portion, the second matching portion is reset and interlocked with the first matching portion; and / or, a roller is also provided on the lock, and when the lock is triggered and rotated, the roller fits into the cylinder body or the matching portion slides in the cylinder body.

[0020] According to another specific implementation and preferred aspect of the present invention, the docking portion includes a slide rail extending along the direction of entering and exiting the cylinder body, and a pulley installed at the bottom of the bathing assisted seat, wherein the pulley slides on the slide rail. Based on the cooperation of the slide rail and the pulley, the bathing assisted seat can be smoothly sent into the bathtub. In some specific embodiments, there are two slide rails, which are correspondingly distributed on both sides of the width direction of the cylinder body; the pulleys are divided into two groups, and are respectively located on opposite sides of the bottom of the bathing assisted seat. In this way, horizontal pushing is more stable and safe, and at the same time, at least two pulleys are used, and the support effect formed is the best.

[0021] According to another specific implementation and preferred aspect of the present invention, the docking device also includes a receiving ramp portion provided at the bathing port of the cylinder body, wherein the receiving ramp portion gradually slopes downward from the inside to the outside; and / or, the docking device also includes a receiving channel provided at the bottom of the cylinder body, wherein the walking chassis enters the bottom of the cylinder body along the receiving channel. Based on the setting of the receiving ramp portion, it is convenient for the separated bathing assistance seat to enter and exit the cylinder body from the bathing port, reducing collision damage, while meeting the requirements of the position alignment required for separation and combination. The setting of the receiving channel realizes the movement guidance of the walking chassis. It is convenient to cause a collision between the walking chassis and the cylinder body, and can meet the requirements of the position alignment required for separation and combination.

[0022] In addition, the cylinder moving chassis includes moving wheels and positioning support modules on opposite sides, wherein the bottom surfaces of the moving wheels and the positioning support modules are flush with each other to form a support surface. That is, after the positioning support module is lifted upward, the cylinder can be displaced based on the moving wheels. At the same time, a lifting handle is formed on the door, so that the cylinder can be displaced by operating the lifting handle.

[0023] Preferably, the cylinder body gradually becomes smaller from top to bottom, and a support stand is fixedly provided at the front end of the cylinder body, wherein the front end of the support stand is flush with the front end of the cylinder body to form a mounting surface. Here, the main functions of the support stand are: 1. Assisting positioning, when the cylinder body is placed horizontally, the mounting surface can form a positioning grid surface; when the cylinder body is placed vertically, the mounting surface is in contact with the ground, that is, completing the placement assistance; 2. It can still play a supporting role during the movement process and at the same time protect the cylinder body.

[0024] Due to the implementation of the above technical solution, the present invention has the following advantages compared with the prior art:

[0025] In the existing bathing assistance vehicles, the common shift vehicles cannot separate the seat and the walking chassis. Therefore, the whole vehicle occupies a large space after entering the bathtub and has a high center of gravity. If bathing is to be carried out, a larger bathtub is required and more bath liquid is required. In addition, the walking chassis will also cause bath liquid pollution, resulting in a poor bathing service experience and difficult operation for the bathing assistant. In addition, the overall mobility is not convenient enough to meet the needs of door-to-door service, resulting in low practicality. At the same time, the required sitting or lying posture adjustment cannot be formed during bathing, which further increases the difficulty of implementation for the bathing assistant and also greatly reduces the comfort of bathing and other deficiencies. The present invention cleverly solves the various deficiencies of the existing structure by overall design of the split and combined bathing assistance equipment. After adopting the split-and-combined bathing assistance device, the door is first opened to form a bathing entrance, the shifting vehicle is aligned with it, and then the self-service bathing seat of the shifting vehicle enters the cylinder body, and the self-propelled chassis enters the bottom of the cylinder body, until the cylinder body triggers the lock to rotate, the lock head and the lock seat are disengaged to separate the bathing assistance seat from the walking chassis, and at the same time the matching part is linked and interlocked with the alignment part to relatively position the walking chassis and the bottom of the cylinder body, the bathing assistance seat enters the cylinder body along the guided docking part, and then the door is closed to enable the user to bathe on the bathing assistance seat. Therefore, the present invention On the one hand, based on the touch unlocking formed by the shifting cart and the cylinder body and the guiding and interlocking linkage formed by the docking part and the alignment part, the precise alignment of the shifting cart for bathing and exiting is achieved, so that the bathing assistance seat can enter and exit the bathtub alone, and as the shifting cart for bathing and exiting switches between the separate part and the combined part, the bathing operation of the bathing assistant is convenient; on the other hand, the sitting and lying posture formed by the bathing assistance seat itself is adjustable to improve the user's bathing comfort and thereby increase the user's physical sensation. In addition, it can also prevent the walking chassis from entering and causing contamination of the bath fluid. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] like Figures 1 to 10 As shown, the bathing assistance equipment involved in this embodiment includes a bathing assistance bathtub 1, a shifting vehicle 2 and a docking device 3.

[0046] In some specific embodiments, the bathing-assisted bathtub 1 includes a cylinder body 10, a door 11 that is flipped sideways from the end of the cylinder body 10 to open or close, and a cylinder body movable chassis 12, wherein after the door 11 is opened, the open end of the cylinder body 10 forms a bathing inlet.

[0047] In this example, the cylinder body 10 gradually becomes smaller from top to bottom, and a support leg 13 is fixedly provided at the front end of the cylinder body 10, wherein the front end of the support leg 13 is flush with the front end of the cylinder body 10 to form a mounting surface. Here, the main functions of the support leg are: 1. Auxiliary positioning. When the cylinder body is placed horizontally, the mounting surface can form a positioning grid surface; when the cylinder body is placed vertically, the mounting surface is in contact with the ground, that is, placement assistance is completed; 2. It can still play a supporting role during the movement process and at the same time protect the cylinder body. Specifically, the support leg 13 is a U-shaped rod, and is fixed to the front end of the cylinder body 10 by an external connection. The cylinder body moving chassis 12 includes moving wheels 120 located on opposite sides and positioning support modules 121 located on opposite sides, wherein the bottom surfaces of the moving wheels 120 and the positioning support modules 121 are flush to form a supporting surface. That is, after lifting the positioning support module upward, the cylinder body can be displaced based on the moving wheels. At the same time, a lifting handle 110 is formed on the warehouse door 11, so that the cylinder body 10 can be displaced by operating the lifting handle. At the same time, the warehouse door 11 and the cylinder body 10 can be sealed, docked and locked.

[0048] The shifting vehicle 2 includes a bathing-assisting seat 20 capable of adjusting the sitting posture, and a walking chassis 22 separately installed at the bottom of the bathing-assisting seat 20 through a self-locking component 21, wherein the self-locking component 21 includes a lock seat 210 installed on the walking chassis 22, and a lock head 211 rotatably arranged at the bottom of the bathing-assisting seat 20 and cooperating with the lock seat 210. In some specific embodiments, the bathing-assisting seat 20 includes a chair body 200, a cushion portion 201 formed on the chair body 200 and relatively rotatably connected, a backrest portion 202, and a leg support portion 203, wherein the cushion portion 201, the backrest portion 202, and the leg support portion 203 are adjusted relative to the chair body 200 to change the user's sitting or lying posture on the bathing-assisting seat 20; the walking chassis 22 is separately assembled with the bottom of the chair body 200 through the self-locking component 21.

[0049] The alignment device 3 includes a docking part 30 and an alignment part 31, wherein when taking a bath, the cylinder body 10 triggers the self-locking component 21 to unlock, the bathing assistance seat 20 and the walking chassis 22 are separated, and the docking part 30 guides the bathing assistance seat 20 to the cylinder body 10; the alignment part 31 interlocks the walking chassis 22 with the bottom of the cylinder body 10 based on the synchronous linkage formed by unlocking; when getting out of the bath, the bathing assistance seat 20 withdraws from the docking part 30, the self-locking component 21 resets to form self-locking, and the alignment part 31 unlocks the walking chassis 22 relative to the bottom of the cylinder body 10 based on the synchronous linkage formed by self-locking, and the bathing assistance seat 20 and the walking chassis 22 are combined.

[0050] In some specific embodiments, the docking portion 30 includes a slide rail 300 extending along the direction of entering and exiting the tub body 10, and a pulley 301 installed at the bottom of the bathing seat 20, wherein the pulley 301 slides on the slide rail 300. Based on the cooperation of the slide rail and the pulley, the bathing seat can be smoothly sent into the bathtub. In this example, there are two slide rails 300, which are correspondingly distributed on both sides of the width direction of the tub body 10; the pulley 301 is divided into two groups, and is respectively located on opposite sides of the bottom of the bathing seat 20. In this way, the horizontal push is more stable and safe, and at the same time, at least two pulleys are used, and the support effect formed is the best.

[0051] The alignment part 31 includes a first matching part 311 fixedly mounted on the bottom of the cylinder body 10, and a second matching part 312 mounted on the chair body 200 through a torsion spring, wherein the second matching part 312 is linked with the lock head 211. When the lock head 211 is disengaged from the second matching part 312, the lock head 211 and the lock seat 210 are unlocked, and the second matching part 312 is reset and docked and interlocked with the first matching part 311. In some specific embodiments, one of the first matching part 311 and the second matching part 312 is a lock hook, and the other is a locking module in a hook shape, a block shape, or a rod shape. The hooking method makes the docking of the two more stable.

[0052] In this example, the lock seat 210 includes a seat body T having a platform portion a and a slope foot portion b. When self-locking is formed, the lock head 211 contacts the junction of the platform portion a and the slope foot portion b. The relative movement of the lock head 211 is limited by the blocking formed by the slope foot portion b and the torsion force of the torsion spring itself. The lock head 211 is installed at the bottom of the chair body 200 by a torsion spring that maintains a downward movement trend. Here, the automatic reset of the lock head is achieved based on the torsion spring. A pressure rod g1 is also provided on the lock head 211, wherein the pressure rod g1 can be pressed on the second matching portion 312 to form a linkage. When the pressure rod g1 is separated from the second matching portion 312, the second matching portion 312 is reset and interlocked with the first matching portion 311. That is, the self-locking or unlocking is linked to the state of the second matching portion 312 by the triggering or separation of the pressure rod g1, so that when the body is combined, the second matching portion 312 is separated from the first matching portion 311; when the body is separated, the second matching portion 312 is interlocked with the first matching portion 311. The lock head 211 is also provided with a roller g2. When the lock head 211 is triggered and rotated, the roller g2 slides in the cylinder body 10 by fitting the cylinder body 10 or the docking portion 31. The rolling energy formed by the roller can prevent the lock head from causing movement damage to the cylinder body. At the same time, a resistance limit module 212 is provided at the bottom of the cylinder body 10, and a movable lock hook 213 is provided on the lock seat 210 to keep the lock head 211 hooked to the slope foot b. When the split operation is performed, the movable lock hook 213 is resisted by the resistance limit module 212 and drives the movable lock hook 213 to separate from the lock head 211.

[0053] In some specific embodiments, the movable locking hook 213 is slidably arranged along the length direction of the seat body T, and a positioning seat 214 and a tension spring 215 are also provided on the walking chassis 22, wherein the two ends of the tension spring 215 are respectively installed on the positioning seat 214 and the movable locking hook 213 to maintain the tensioning hooking trend to form self-locking of the locking head 211 and the locking seat 210.

[0054] In this example, a trigger rod g3 is provided on the movable lock hook 213, wherein the contact limit module 212 and the trigger rod g3 contact to drive the movable lock hook 213 to slide and unhook. Here, the equivalent movement of the movable lock hook 213 and the combined and separated movement also form a linkage to further improve the stability and safety of the self-locking of the lock head and the lock seat.

[0055] In addition, the docking device 3 also includes a receiving channel 33 arranged at the bottom of the cylinder body 10 and a receiving ramp portion 34 arranged at the bathing port of the cylinder body 10, wherein the walking chassis 22 enters the bottom of the cylinder body 10 along the receiving channel 33, that is, the movement guidance of the walking chassis is realized by the setting of the receiving channel; the receiving ramp portion 34 gradually tilts downward from the inside to the outside. Based on the setting of the receiving ramp portion 34, it is convenient for the separated bathing seat 20 to enter and exit the cylinder body 10 from the bathing port, reduce collision damage, and at the same time meet the requirements of the position alignment required for separation and combination.

[0056] In summary, the bathing process of this embodiment is as follows:

[0057] After the warehouse door 100 is opened to form a bathing entrance, the shifting cart 2 is aligned with it, and then the self-service bathing seat 20 of the shifting cart 2 enters the cylinder body 10, and the self-propelled chassis 22 enters the bottom of the cylinder body 10, until the unlocking module 212 is triggered to contact the trigger rod g3 to drive the movable lock hook 213 to slide and unhook, and then when the cylinder body 10 triggers the lock head 211 to rotate, the lock head 211 is disengaged from the lock seat 210 to separate the bathing seat 20 from the walking chassis 22, and at the same time, the second matching part 312 is linked and interlocked with the first matching part 311 to relatively position the walking chassis 22 and the bottom of the cylinder body 10, and the bathing seat 20 enters the cylinder body 10 along the guiding docking part 30, and then the warehouse door 100 is closed to enable the user to bathe on the bathing seat 20 (by adjusting the angle of the bathing seat 20 to reflect a comfortable sitting and lying posture).

[0058] The bathing process of this embodiment is as follows:

[0059] After opening the door 100, the bath-assisting seat 20 is moved outward from the outer cylinder body 10. When the lock head 211 loses its restriction and rotates downward to the aligned lock seat 210 under the reset of the torsion spring, the pressure rod g1 contacts the second matching part 312 to unlock the second matching part 312 and the aligned part 31. Then, the trigger rod g3 disengages from the interference limit module 212, and under the pull of the tension spring 215, the movable lock hook 213 is hooked on the lock head 211. The lock head 211 is in contact with the junction of the platform part a and the slope foot part b and forms a self-locking with the lock seat 210 to complete the relative combination of the bath-assisting seat 20 and the walking chassis 22.

[0060] Therefore, after adopting the split-and-combined bathing-assisting device, the door is first opened to form a bathing entrance, the shifting vehicle is aligned with it, and then the self-service bathing seat of the shifting vehicle enters the cylinder body, and the self-propelled chassis enters the bottom of the cylinder body, until the cylinder body triggers the lock to rotate, the lock and the lock seat are disengaged to separate the bathing-assisting seat from the walking chassis, and at the same time the matching part is linked and interlocked with the alignment part to relatively position the walking chassis and the bottom of the cylinder body, the bathing-assisting seat enters the cylinder body along the guided docking part, and then the door is closed to enable the user to bathe on the bathing-assisting seat. Therefore, on the one hand, the present invention is based on the trigger unlocking formed by the shifting vehicle and the cylinder body and the guiding and interlocking linkage formed by the docking part and the alignment part to achieve precise alignment of the shifting vehicle for bathing separation and bathing combination. The bathing assistant seat can enter and exit the bathtub alone, and the transfer vehicle can be switched between the split and combined parts as the bathing and exiting parts are entered and exited, so as to facilitate the bathing operation of the bathing assistant. On the other hand, the bathing assistant seat itself can be adjusted to form a sitting and lying posture, so as to improve the comfort of the user's bathing and thus increase the user's body feeling. In addition, it can also avoid the walking chassis from entering and causing bath liquid contamination. On the third hand, based on the cooperation of the slide rail and the pulley, the bathing assistant seat can be smoothly sent into the bathtub, and such a horizontal push is more stable and safe. At the same time, at least two pulleys are used, and the support effect is best. On the fourth hand, based on the interlocking of the alignment part and the matching part, the walking chassis and the cylinder body after the separation are relatively locked. On the contrary, when the bathing assistant seat is withdrawn, the alignment part and the matching part can be implemented. The separation is based on the locking head being installed on the bottom of the bath-assisting seat through a torsion spring that maintains a downward movement trend. Here, the automatic resetting of the locking head is realized based on the torsion spring. At the same time, a pressure rod is also provided on the lock head, wherein the pressure rod can be pressed on the matching part to form a linkage. When the pressure rod is separated from the matching part, the matching part is reset and interlocked with the positioning part, that is, the self-locking or unlocking is linked with the matching part state by the triggering or disengagement of the pressure rod, so that when combined, the matching part and the positioning part are separated; when separated, the matching part and the positioning part are interlocked, and then a pressure rod is also provided on the lock head.
