Description

Technical Field

[0001] This invention relates to the field of shifting machine technology, and more specifically, to a shifting machine with training function and a method of using it. Background Technology

[0002] As a key piece of equipment in the fields of medical care and rehabilitation, patient transfer machines are widely used in hospitals, health and rehabilitation centers, nursing homes, and other institutions, and are also gradually entering home settings where care needs for people with mobility impairments are met. Their core purpose is to provide safe and convenient positional support for bedridden individuals, those with limited limb movement, or those experiencing declining mobility. They help users flexibly switch between different settings such as beds, wheelchairs, toilets, and bathing facilities, serving as an important tool to ensure the self-care ability of these individuals and improve their quality of life. They are also core equipment for reducing the caregiving burden on nursing staff and optimizing care processes. With the increasing aging population and the continuous advancement of medical rehabilitation concepts, the market demand for patient transfer machines continues to grow, and their application scenarios are expanding from professional medical settings to home care.

[0003] Existing patient transfer machines mostly rely on hand-cranked or foot-operated hydraulic mechanisms for seat height adjustment. These purely mechanical or semi-mechanical methods require significant manual effort from caregivers, resulting in cumbersome operation and a substantial increase in workload. Furthermore, traditional transfer machines do not consider the rehabilitation needs of individuals who are bedridden for extended periods, have limited limb mobility, or are temporarily immobile due to injury. These users are prone to muscle atrophy and joint stiffness due to a lack of active lower limb exercise. Existing transfer machines cannot meet the integrated needs of nursing care and rehabilitation; therefore, there is an urgent need for a transfer machine with training functions to address these issues. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a transfer machine with training function and its usage method, which is suitable for various indoor scenarios such as hospitals, nursing homes, and homes. It not only ensures the convenience and safety of nursing work, but also provides users with personalized rehabilitation solutions, thus having good social benefits and practical value.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: A shifter with training capabilities includes: A balancer includes a housing, a rotatable balancer horizontal shaft housed inside the housing, a worm gear assembly, a balancer tower wheel, a balancer worm coil spring, and a steel wire rope A. Several balancer worm coil springs are provided, each sleeved on the balancer horizontal shaft. One end of each worm coil spring is fastened into a slot on the balancer horizontal shaft, and the other end is fastened into a groove on a spring box. The worm gear assembly's worm wheel is mounted on the spring box, and the worm of the worm gear assembly is mounted inside the housing via a frame. The balancer tower wheels are installed at both ends of the balancer horizontal shaft, and one end of the steel wire rope A is fixed to and wound around the balancer tower wheel. The balancer has casters and swivel wheels located on the front and rear sides, and an auxiliary pedal is provided between the two casters; A guide column is installed on the balancer, and a guide sleeve is provided on the guide column. A guide sleeve roller is provided on the guide sleeve. A seat is provided near the top of the guide sleeve. The seat unfolds and closes as the guide sleeve rotates. A handle is also installed on the guide sleeve. The pulley installed inside the guide sleeve, the steel wire rope A passing through the guide post, and then around the pulley is secured to the lower support assembly; A connecting suspension is installed at the bottom of the guide sleeve, and a training pedal is installed at the other end of the connecting suspension. A steel wire rope B is installed on the training pedal, and the other end of the steel wire rope B is installed on a winder.

[0006] In a preferred embodiment of the present invention, the casters are mounted on rearward-extending rear support legs, which are mounted on the housing of the balancer.

[0007] As a preferred embodiment of the present invention, the seat includes side frames that provide support and protection, and the two side frames are connected by a seat locking device, which includes a buckle and a buckle seat. A seat plate is installed on the inner side of the side frame, and a seat belt is provided on the side frame.

[0008] As a preferred embodiment of the present invention, the seat plate is provided with an arc-shaped groove in the middle.

[0009] As a preferred embodiment of the present invention, the connecting suspension includes an upper deployable arm and a lower deployable arm that are hinged together. The other end of the lower deployable arm is rotatably connected to a lower mounting part. The other end of the upper deployable arm is connected to an upper bracket and an upper mounting part. The upper mounting part is connected to the guide sleeve. The lower mounting part is connected to the training pedal. The connecting suspension also includes a plurality of limiting pins and a limiting structure through which the wire rope B passes.

[0010] As a preferred embodiment of the present invention, the winding device includes a winding worm spring and a winding tower wheel. The winding tower wheel is provided with an annular groove for accommodating the wire rope B. The rotating shaft of the winding tower wheel is engaged with the inner end of the winding worm spring, and the outer end of the winding worm spring is engaged with the outer shell of the winding device.

[0011] As a preferred embodiment of the present invention, the worm end of the worm gear assembly is provided with an internal hexagonal socket, which protrudes from the housing of the balancer.

[0012] As a preferred embodiment of the present invention, the lower support assembly is provided with 5 adjustment plates, and the initial height of the seat can be adjusted by inserting the wire rope A into the adjustment plates at different positions.

[0013] The present invention also provides a method of using a transfer machine with lower limb training function, comprising the following steps: S1. Based on the bed height of the usage scenario, insert the A-shaped end of the steel wire rope connected to the balancer into the U-shaped groove on the corresponding adjustment plate in the lower support assembly. By selecting the position of the 5 adjustment plates, the initial height of the seat is adapted. S2. Rotate the seat along the guide sleeve to 180°, push the transfer machine next to the user, and step on the brake pads of the caster wheel to fix the device; S3. Assist the user to sit on the seat, close the two side frames of the seat and lock them with the buckles and buckles of the seat lock, fasten the seat belt on the side frame to the user, and release the brake pads of the caster wheels. S4. Use the adapter tool to insert the internal hexagonal socket of the worm gear assembly, rotate the worm to drive the worm gear and spring box to rotate synchronously, thereby adjusting the deformation of the balancer coil spring sleeved on the balancer horizontal axis, so that the tension generated by the balancer coil spring is balanced with the user's weight. S5. Push the transfer machine to move it flexibly through the cooperation of the casters on the universal wheels and the rear support legs. After moving it to the target position, press the brake pad of the universal wheel again to fix it. At this time, the caregiver pushes and pulls the handle up and down, which drives the guide sleeve on the outside of the guide column to slide along the guide column. At the same time, the steel wire rope A moves adaptively along the pulley inside the guide sleeve to adjust the seat height to a suitable scenario and assist the user in using or getting up. S6. Assist the user in placing their legs on the training pedal connected to the suspension end, and attach weighted leg straps; adjust the seat height so that the training pedal is on the auxiliary pedal. The user actively pushes on the training pedal, performing a leg extension and standing motion. The effective pressure of the user on the seat decreases, causing the seat to rise under the action of the balancer. During the seat's ascent, the retractor rises along with the guide sleeve, thus stretching the steel cable B14. This stretches the retractor's tower pulley around its axis, causing the retractor's coil spring to be stretched and deformed. When the user stops the leg extension and actively lifts their lower limbs, fully seated on the seat, the user's effective weight on the seat returns to its initial state. Furthermore, the added weight of the leg weights makes the total downward force greater than the upward pull of the balancer. Under the influence of gravity, the guide sleeve and seat slowly descend, and the retractor moves down synchronously with the guide sleeve. The stretched steel wire rope B is no longer pulled, and the retracting worm spring releases its stored elastic potential energy, pulling the retracting tower wheel to rotate in the opposite direction and retract the steel wire rope B. After the steel wire rope B is retracted and shortened, the upper and lower extension arms move inward until the positioning pin abuts against the positioning groove. The seat descends to the lowest point and stops, repeating the above reciprocating motion to achieve leg exercise. S7. Remove the weighted leg braces from the user's legs, unfasten the seat belt and unlock the seat, rotate the seat along the guide sleeve to help the user get up; push the transfer machine to the storage position, step on the brake pads of the caster wheels to fix the device, and the use is complete.

[0014] The present invention has the following beneficial effects: This invention achieves core labor-saving by optimizing the balancer assembly. The balancer incorporates a spiral spring, which, in conjunction with a worm gear assembly, precisely adjusts the spring deformation, ensuring the spring tension is perfectly balanced with the user's weight. Simultaneously, guide rollers on the guide sleeve significantly reduce sliding friction between the guide sleeve and the guide post. Steel wire rope A, via pulleys inside the guide sleeve, alters the direction of force transmission, further reducing operational resistance. Caregivers do not need to exert significant force against the user's weight; only minimal force is required to smoothly raise and lower the seat using the handle. Combined with the seat's 180° rotatable design, it facilitates quick seating and repositioning, greatly simplifying the operational process and effectively reducing the physical exertion of caregivers in long-term care settings.

[0015] This invention utilizes a linkage structure formed by the training pedal, steel wire rope B, and reel connected to the bottom of the guide sleeve and suspension. After repositioning, the user can place both legs on the training pedal and attach weighted leg braces, then actively exercise the lower limb muscles by pushing off, effectively preventing complications such as muscle atrophy and joint stiffness. The ingenious design of the balancer makes the exercise process easier. No additional professional rehabilitation equipment is required, achieving an integrated design of repositioning care and rehabilitation training. This saves space and cost, provides users with a convenient and safe training method, and significantly improves rehabilitation outcomes and quality of life.

[0016] The invention has a compact overall structure and is suitable for various indoor settings such as hospitals, nursing homes, and homes. It not only ensures the convenience and safety of nursing work, but also provides users with personalized rehabilitation solutions, thus having good social benefits and practical value.

[0019] In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, the specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0020] Combination Figures 1-8 The present invention provides the following embodiments: A shifter with training capabilities includes: Balancer 1 includes a housing, a rotatable balancer horizontal shaft 16 housed inside the housing, a worm gear assembly 17, a balancer tower wheel 18, balancer coil springs 20, and a steel wire rope A21. The housing is integrally formed from high-strength aluminum alloy, making it lightweight yet with high load-bearing capacity. Several balancer coil springs 20 are provided, each sleeved on the balancer horizontal shaft 16. One end of each coil spring 20 is fastened into a slot in the balancer horizontal shaft 16, and the other end is fastened into a groove on the spring box 24. Figure 2 As shown, the spring box 24 is fixedly installed inside the housing of the balancer 1, the worm gear assembly 17 is mounted on the spring box 24, the worm of the worm gear assembly 17 is mounted inside the housing through the frame, the balancer tower wheel 18 is installed at both ends of the balancer horizontal shaft 16, and one end of the steel wire rope A21 is fixed to the balancer tower wheel 18 and wound around the balancer tower wheel 18. The swivel wheels 2 and casters 4 are located on the front and rear sides of the balancer 1, and an auxiliary pedal 5 is also provided between the two swivel wheels 2; A guide post 6 is installed on the balancer 1. A guide sleeve 7 is provided on the guide post 6. A guide sleeve roller 8 is provided on the guide sleeve 7. The guide sleeve roller 8 can convert the sliding friction between the guide sleeve and the guide post into rolling friction. A seat 9 is provided near the top of the guide sleeve 7. The seat 9 unfolds and closes as the guide sleeve 7 rotates. A handle 11 is also installed on the guide sleeve 7. The pulley 22 installed inside the guide sleeve 7 passes through the steel wire rope A21 of the guide post 6, goes around the pulley 22, and is then locked onto the lower support assembly 23; A connecting suspension 13 is installed at the bottom of the guide sleeve 7, and a training pedal 12 is installed at the other end of the connecting suspension 13. A steel wire rope B14 is installed on the training pedal 12, and the other end of the steel wire rope B14 is installed on the winder 15. Both steel wire rope A21 and steel wire rope B14 are made of stainless steel with a tensile strength of not less than 1500MPa to prevent breakage during use.

[0021] The balancer 1 counteracts the user's weight by pulling, and the guide rollers 8 reduce drag, greatly reducing the lifting force of the seat 9, saving caregivers and family members' energy. At the same time, the training pedal 12 and the retractor 15 work together to achieve active lower limb training, ultimately achieving the effect of effortless transfer and rehabilitation training. The entire device is waterproof and can be used in humid environments such as bathrooms and shower rooms.

[0022] Furthermore, casters 4 are mounted on rearward-extending support legs 3, which are mounted on the housing of the balancer 1. The rear support legs 3 are securely connected to the housing of the balancer, and their rearward extension serves to prevent tipping and improve safety.

[0023] Furthermore, the seat 9 includes side frames that provide support and protection. The two side frames are connected by a seat locking device 91, which includes a buckle and a buckle seat. A seat plate is installed on the inner side of the side frames, and a safety belt 10 is installed on the side frames. Referring to the attached diagram, the safety belt 10 is installed on an arched handle at the rear end of the side frames. The arched handle also facilitates the caregiver's gripping and pushing of the transfer machine. The seat locking device 91 is simple and convenient to operate and provides a secure lock, while the safety belt 10 also enhances safety protection.

[0024] Furthermore, an arc-shaped groove is provided in the center of the seat. Referring to the attached diagram, this facilitates toilet use, expands the usage scenarios, and enhances practicality.

[0025] Furthermore, the connecting suspension 13 includes an articulated upper extender arm 134 and a lower extender arm 135. The other end of the lower extender arm 135 is rotatably connected to the lower mounting part 131. The other end of the upper extender arm 134 is connected to the upper bracket 132 and the upper mounting part 133. The upper mounting part 133 is connected to the guide sleeve 7, and the lower mounting part 131 is connected to the training pedal 12. The connecting suspension 13 also includes several limiting pins and a limiting structure through which the steel wire rope B14 passes. The overall structure of the connecting suspension 13 is as follows: Figure 9 As shown.

[0026] Furthermore, the winding device 15 includes a winding worm spring 151 and a winding pulley 152. The winding pulley 152 is provided with an annular groove for accommodating the wire rope B14. The rotating shaft of the winding pulley 152 is engaged with the inner end of the winding worm spring 151, and the outer end of the winding worm spring 151 is engaged with the outer shell of the winding device 15.

[0027] When the user steps on the training pedal 12, the wire rope B14 pulls the winding tower wheel 152 to rotate, and the winding worm spring 151 is compressed to store elastic potential energy. When it is relaxed, the elastic potential energy is released, which drives the winding tower wheel 152 to rotate in the opposite direction to retract the wire rope B14, so as to realize the automatic reset of the training pedal 12 and ensure that the training action is smooth and continuous.

[0028] Furthermore, the worm end of the worm gear assembly 17 is provided with an internal hexagonal socket, which protrudes from the housing of the balancer 1. The worm meshes with the turbine, and by rotating the worm, the turbine and spring box 24 are driven to rotate, thereby adjusting the deformation of the balancer coil spring 20, achieving a precise balance between the tension and the user's weight, which is convenient to operate and has high adjustment accuracy.

[0029] Furthermore, the lower support assembly 23 is equipped with five adjustment plates 231. By engaging the steel wire rope A21 with the adjustment plates 231 at different positions, the initial height of the seat 9 can be adjusted. The five adjustment plates 231 are arranged from top to bottom, and each adjustment plate 231 has a U-shaped groove with an opening to securely hold the cylindrical end of the steel wire rope A21. By selecting different positions of the adjustment plates 231 to fix the steel wire rope A21, the initial suspension height of the seat 9 can be changed to meet the height adaptation requirements of different usage scenarios without additional disassembly and adjustment, thus improving the versatility of the equipment.

[0030] The present invention also provides a method of using a transfer machine with lower limb training function, comprising the following steps: S1. Based on the bed height of the usage scenario, insert the columnar end of the steel wire rope A21 connected to the balancer 1 into the U-shaped groove on the corresponding adjustment plate 231 in the lower support assembly 23. By selecting the positions of the 5 adjustment plates 231, the initial height adaptation of the seat 9 is completed. S2. Rotate the seat 9 along the guide sleeve 7 to 180°, push the transfer machine next to the user, and step on the brake pad of the universal wheel 2 to fix the device. S3. Assist the user to sit on the seat of the seat 9, close the two side frames of the seat 9 and lock them with the buckle and seat of the seat lock 91, fasten the seat belt 10 on the side frame to the user, and release the brake pad of the universal wheel 2. S4. Use the adapter tool to insert into the hexagonal socket of the worm gear assembly 17, rotate the worm to drive the worm gear and spring box 24 to rotate synchronously, thereby adjusting the deformation degree of the balancer coil spring 20 sleeved on the balancer horizontal shaft 16, so that the tension generated by the balancer coil spring 20 is balanced with the user's weight. S5. Push the transfer machine, and move it flexibly by cooperating with the casters 4 on the universal wheels 2 and the rear support legs 3. After moving to the target position, step on the brake pad of the universal wheels 2 again to fix it. At this time, the caregiver pushes and pulls the handle 11 up and down, which drives the guide sleeve 7 sleeved on the guide column 6 to slide along the guide column 6. At the same time, the steel wire rope A21 moves adaptively along the pulley 22 inside the guide sleeve 7, and adjusts the height of the seat 9 to the appropriate scenario to assist the user in using or getting up. S6. Assist the user to place both legs on the training pedal 12 connected to the end of the suspension 13, and attach weighted leg straps to the legs; adjust the seat height so that the training pedal 12 is on the auxiliary pedal 5. The user actively pushes on the training pedal 12 to perform a leg extension and standing-up motion. The effective pressure of the user on the seat 9 decreases, so the seat 9 rises under the action of the balancer 1. During the rising of the seat 9, the retractor 15 rises along with the guide sleeve 7, so the steel cable B14 is stretched, which in turn pulls the winding tower wheel 152 inside the retractor 15 to rotate around the axis. The winding tower wheel 152 drives the winding worm spring 151 to be stretched and deformed. When the user stops the leg extension and standing-up motion and actively raises his / her lower limbs to sit fully on the seat 9, the effective weight of the user on the seat 9 returns to the initial weight state, and The added weight of the leg weights makes the total downward force greater than the upward pull of the balancer 1. Under the influence of the gravity difference, the guide sleeve 7 and seat 9 slowly descend, and the retractor 15 moves down synchronously with the guide sleeve 7. The stretched steel wire rope B14 is no longer pulled, and the winding coil spring 151 releases the stored elastic potential energy, pulling the winding tower wheel 152 to rotate in the opposite direction and retract the steel wire rope B14. After the steel wire rope B14 is retracted and shortened, the upper extension arm 134 and the lower extension arm 135 move inward until the positioning pin abuts against the positioning groove. The seat 9 stops at the lowest point and repeats the above reciprocating action to achieve leg exercise. S7. Remove the weighted leg braces from the user's legs, unfasten the seat belt 10 and open the seat lock 91, rotate and unfold the seat 9 along the guide sleeve 7 to assist the user in getting up; push the transfer machine to the storage position, step on the brake pad fixing device of the universal wheel 2 to complete the use.

[0031] The balancer coil spring 20 inside the balancer 1 is sleeved on the balancer horizontal shaft 16. One end is fastened to the slot of the horizontal shaft, and the other end is fastened to the groove of the spring box 24. In the initial state, the elastic potential energy is stored by the preload of the coil spring. After the user sits down, the worm of the worm gear assembly 17 is rotated by a tool, which drives the worm and the spring box 24 to rotate synchronously, thereby adjusting the deformation degree of the balancer coil spring 20, so that the tension generated by the coil spring is balanced with the user's weight and counteracts the weight load.

[0032] The balancer tower wheel 18 rotates with the horizontal axis, and the steel wire rope A21 wound on it changes the direction of the force through the pulley 22 in the guide column 6, and finally connects to the lower support assembly 23, so as to transmit the balancing pull of the balancer to the seat 9, providing a labor-saving basis for seat lifting.

[0033] During exercise, weighted leg straps are required. When performing leg extension and standing movements, the effective pressure on the seat 9 is reduced, so the seat 9 rises under the action of the balancer 1. During the rising process, the continuous support of the seat 9 allows the user to start exercising without having to resist their own main body weight, and only needs to output two small forces.

[0034] After completing a single leg extension, relax or sit completely on seat 9. Because of the weighted leg straps, seat 9 will slowly descend and stop at the lowest point.

[0035] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.

Assist the user to place both legs on the training pedal (12) at the end of the suspension (13) and attach weighted leg straps to the legs; Adjust the seat height so that the training pedal (12) is on the auxiliary pedal (5). The user actively pushes the training pedal (12) to perform a leg extension and stand-up movement. The effective pressure of the user on the seat 9 decreases, so the seat 9 rises under the action of the balancer 1. During the rise of the seat 9, the retractor 15 rises along with the guide sleeve 7, so the wire rope B14 is stretched, which in turn pulls the retractor pulley (152) inside the retractor (15) to rotate around the axis. The retractor pulley (152) drives the retractor coil spring (151) to be stretched and deformed. When the user stops the leg extension and stand-up movement and actively raises his / her lower limbs and sits completely on the seat (9), the effective weight of the user on the seat (9) returns to the initial weight state, and the leg load is superimposed. The weight of the leg wraps makes the total downward force greater than the upward pull of the balancer (1); under the action of gravity difference, the guide sleeve (7) and the seat (9) slowly descend, the retractor (15) moves down synchronously with the guide sleeve (7), the stretched steel wire rope B (14) is no longer pulled, the winding worm spring (151) releases the stored elastic potential energy, pulls the winding tower wheel (152) to rotate in the opposite direction, and retracts the steel wire rope B (14). After the steel wire rope B (14) is retracted and shortened, the upper unfolding arm (134) and the lower unfolding arm (135) move inward until the positioning pin abuts against the positioning groove; the seat (9) stops at the lowest point, and the above reciprocating action is repeated to achieve leg exercise; S7. Remove the weighted leg straps from the user's legs, unfasten the seat belt (10) and open the seat lock (91), rotate and unfold the seat (9) along the guide sleeve (7) to help the user get up; push the transfer machine to the storage position, step on the brake pad fixing device of the universal wheel (2) to complete the use.
