Description

Technical Field

[0001] This utility model relates to the field of transfer vehicles, specifically a simplified transfer vehicle. Background Technology

[0002] The current transfer cart structure, as shown in prior art 1 (application number: 202322235169.2), mainly includes a base assembly, two uprights on the base assembly, and a seat assembly that is raised and lowered via the two uprights. The two uprights are vertically mounted at both ends of the top of a support beam, and a lifting component is provided on the support beam between the two uprights to drive the seat assembly to rise and fall. When using this transfer cart, the user's legs need to be positioned within the gap between the uprights and the lifting component. This structure restricts the lateral movement space of the user's legs, affecting the comfort of riding the transfer cart. In addition, a seat frame and armrest frame need to be additionally connected to the two uprights for installing the seat and armrest cushions, making the frame structure of the transfer cart more complex and larger in size, which affects the storage effect when folding is required.

[0003] For example, in prior art 2, application number 202322221631.3, a safety locking type transfer cart mainly includes an H-shaped frame, a base at the bottom of the frame, and left and right seats respectively rotatably mounted on both sides of the top of the frame. The left and right seats are combined to form a support structure for carrying the patient. As shown in the prior art, the left and right seats of the existing transfer cart cannot be disassembled. Moreover, during use, the left and right seats need to be opened and closed and inserted under the user's buttocks, which is quite restrictive. In addition, the user's body movements are large during the placement process, which is not suitable for users with wounds. Furthermore, when the entire transfer cart is supporting the user, it must be positioned directly in front of the user, and the caregiver can only operate from the side, making the entire placement process inconvenient. Therefore, the applicant has improved and perfected the transfer cart to solve the problems existing in the prior art, so as to provide consumers with a choice for use. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned existing problems and provide a simple and reasonable transfer vehicle.

[0005] A simple transfer cart includes a frame with several swivel casters at the bottom for moving the cart. The frame includes a base and a single lifting column connected to the central axis of the base. A support armrest is connected to the movable end of the lifting column. A single-layer seat cushion is suspended below the support armrest via a hanging connector. The hanging connector has a locking structure, and the seat cushion is detachably connected to the support armrest via the locking structure.

[0006] The objective of this utility model can also be achieved by the following technical measures: As a more specific embodiment, the hanging connector includes several spaced flexible strips, one end of which is fixedly connected to the left or right side of the seat cushion, and the other end of which is connected to a locking structure, which is suspended and connected to the support armrest.

[0007] As a further embodiment, the locking structure includes a buckle and a lock, one of which is connected to the other end of the flexible belt, and the other is connected to the support armrest. Through the buckle and the lock engaging, the seat cushion and the hanging connector are detachably installed as a whole relative to the support armrest.

[0008] As a further embodiment, the base frame includes a base and two support legs; each support leg includes a rear support section and a front support section, the rear support section is connected to the outside of the base, the front support section is rotatably connected to the front end of the rear support section and can be folded inward to the front of the base, and the swivel casters are connected to the outer ends of the rear support section and the front support section.

[0009] As a further embodiment, a handrail support structure is fixedly connected to the front side of the movable end of the lifting column. When the handrail is in the unfolded position, it abuts against the upper side of the handrail support structure, so that the handrail extends laterally to the front side of the lifting column.

[0010] As a further embodiment, the support armrest has a "U" shaped structure, including a middle section and two armrests. The two armrests are symmetrically connected to both ends of the middle section. The seat cushion is connected to the two armrests. The middle section is rotatably connected to the rear side of the movable end of the lifting column through a tube clamp, and the two armrests are flipped back and forth between the unfolded position and the retracted position.

[0011] As a further embodiment, the rear ends of the two support legs are rotatably connected to the outside of the base. The rear side of the base is provided with an external support synchronization mechanism, which is connected to the rear ends of the two support legs. The two support legs are driven to switch between the external support position and the inward position through the external support synchronization mechanism.

[0012] As a further embodiment, the handrail support structure includes a support horizontal tube, with upward-opening pipe clamps at both ends of the support horizontal tube, and the middle of the support horizontal tube is fixedly connected to the lifting column through a connecting block, with the two handrails of the support handrail positioned and abutting inside the pipe clamps.

[0013] As a further embodiment, the length of the flexible strip on each side gradually decreases as it moves away from the lifting column, and the seat cushion is obliquely connected to the underside of the support armrest by flexible strips of different lengths. The two flexible straps connected to the front of the seat cushion are in a cross structure, with the other end of the left flexible strap connected to the right locking structure, and the other end of the right flexible strap connected to the left locking structure.

[0014] As a further embodiment, the cushion is made of a single rigid board; and a defecation opening is provided in the middle of the board.

[0015] The beneficial effects of this utility model are as follows: This utility model discloses a simplified transfer cart. This transfer cart uses a single lifting column to support the armrests and seat, eliminating the need for additional mounting frames and reducing the complexity of the frame structure. The lifting column allows for simultaneous and arbitrary adjustment of the armrests and seat height without requiring separate operation, making it more convenient to use. When the user is seated, the lifting column is positioned between the legs, providing more lateral movement space on the outside of the legs, improving user comfort and reducing leg constraints.

[0016] This transfer cart utilizes a locking mechanism to allow the seat cushion to be detached from the cart and placed under the user's buttocks. This placement process minimizes the user's body movement. The cart can then be moved independently, and the locking mechanism secures the seat cushion to the support armrests. Finally, the user can be lifted. The entire operation is flexible and convenient, minimizing interference with the user and ensuring a seamless transfer experience.

[0017] The support legs and handrails of this transfer cart can be folded for storage, further reducing its size when stored. This eliminates the problem of components being scattered during storage and allows for quick switching between storage and use. It eliminates the need for reinstalling the support legs and / or handrails each time it is reused, improving efficiency and making operation simple and convenient. Even when folded, the four casters remain in contact with the ground, maintaining relatively parallel support points, allowing the cart to remain upright while folded and reducing the space it occupies during storage.

[0018] During use, the support legs of this transfer cart can be extended outward in a figure-eight shape under the drive of the external support synchronization mechanism, thereby increasing the support area to cope with the tilting of the transfer cart due to the shift of the center of gravity caused by the user's body tilting.

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] See Figures 1 to 11 As shown, a simple transfer cart includes a frame 1. The bottom of the frame 1 is provided with several swivel casters 10 for moving the transfer cart. The frame 1 includes a base frame 9 and a single lifting column 4 connected to the central axis of the base frame 9. The movable end of the lifting column 4 is connected to a support armrest 5. The support armrest 5 is vertically connected to a single-board seat cushion 6 placed below it through a hanging connector 7. The hanging connector 7 is provided with a locking structure 8. The seat cushion 6 is detachably connected to the support armrest 5 through the locking structure 8.

[0032] In the above structure, the armrest 5 and seat 6 are supported by a single lifting column 4, so that the frame 1 does not need to add a corresponding mounting frame structure, reducing the complexity of the frame 1 and making the frame 1 structure simpler. In addition, the height of the armrest and seat 6 can be adjusted at the same time by lifting the lifting column 4, without having to operate the two parts separately, making it easier to use. Furthermore, when the user is sitting, the lifting column 4 is placed between the two legs, and the outside of the legs has more lateral movement space, which can improve the user's riding comfort and reduce the restriction on the legs.

[0033] In addition, by unlocking the locking structure 8, the seat cushion 6 can be completely removed from the transfer cart and placed under the user's buttocks. The placement process can reduce the range of motion of the user's body. Afterwards, the transfer cart can be moved independently, and the seat cushion 6 can be fastened to the support armrest 5 through the locking structure 8. Finally, the user can be lifted. The whole operation is flexible and convenient, reduces interference to the user, and makes the user feel the transfer as little as possible.

[0034] The hanging connector 7 includes several flexible strips 71 arranged at intervals. One end of each flexible strip 71 is fixedly connected to the left or right side of the seat cushion 6, and the other end of each flexible strip 71 is connected to the locking structure 8. The locking structure 8 is suspended and connected to the support armrest 5.

[0035] When the support armrest 5 can be folded, the seat cushion 6 is connected to the support armrest 5 by a flexible strap 71, which can save space when folded. Moreover, the flexible connection between the seat cushion 6 and the support armrest 5 can also play a certain role in shock absorption and cushioning during the use of the transfer vehicle, which can improve the comfort of the user.

[0036] The locking structure 8 includes a buckle 81 and a lock 82. One of the buckles 81 and the lock 82 is connected to the other end of the flexible belt 71, and the other of the buckles 81 and the lock 82 is connected to the support armrest 5. Through the buckle 81 and the lock 82, the seat cushion 6 and the hanging connector 7 are assembled as a whole and can be detached from the support armrest 5. This structure allows the seat cushion 6 to be removed as a whole, making it convenient to place under the user's buttocks. Moreover, the buckles 81 and the lock 82 are easy to operate and can be quickly fastened or unfastened.

[0037] The length of the flexible straps 71 on each side gradually decreases from the rear end of the seat cushion 6 to the front end of the seat cushion 6. The seat cushion 6 is inclinedly connected to the lower part of the support armrest 5 by flexible straps 71 of different lengths. When the user is riding in the transfer vehicle, the user will face the rear end of the seat cushion 6. Therefore, the inclined seat cushion 6 can prevent the user's buttocks from sliding backward and play a role in the stability of the ride.

[0038] The two flexible straps 71 connected to the front end of the seat cushion 6 have a cross structure (see attached). Figure 2(The part marked X in the middle), where the other end of the left flexible belt 71 is connected to the right locking structure 8, and the other end of the right flexible belt 71 is connected to the left locking structure 8; the two flexible belts 71 are cross-connected so that the two flexible belts 7 can form a backrest, which can provide a certain support for the user's back and prevent the user from falling backward.

[0039] The support handrail 5 is connected to a suspension belt 84 via a mounting shaft 83. A hanging ring 85 is provided on one side of the buckle 81 or lock 82. The buckle 81 or lock 82 is movably suspended on the support handrail 5 by the cooperation of the hanging ring 85 and the suspension belt 83. The buckle 81 or the lock 82 is connected to the support armrest 5 by the suspension belt 83. When the flexible belt 71 sways with the shift of the center of gravity of the seat cushion 6, the lock structure 8 can also swing with the flexible belt 71. This can avoid the buckle 81 or the lock 82 being fixed, which would increase the stress between them and improve the service life of the lock structure 8.

[0040] The seat cushion 6 is made of a single piece of rigid board; and a defecation port 601 is provided in the middle of the board; the defecation port 601 allows the user to defecate while sitting on the transfer cart, reducing the user's transfer process and improving the convenience of the transfer cart.

[0041] A handrail support structure 11 is fixedly connected to the front side of the movable end of the lifting column 4. When the handrail 5 is in the unfolded position, it abuts against the upper side of the handrail support structure 11, so that the handrail 5 extends laterally to the front side of the lifting column 4.

[0042] Specifically, the handrail support structure 11 includes a support horizontal tube 111, with upward-opening tube clamps 112 at both ends of the support horizontal tube. The middle of the support horizontal tube 111 is fixedly connected to the lifting column 4 through a connecting block 113. The connecting block 113 has an arc that fits the surface of the lifting column 4, making the connection more secure. The two handrails 52 of the support handrail 5 are positioned and abutted against the tube clamps 112 (which can be a clearance fit or an elastic interference fit).

[0043] It can fix the handrail 5 on the handrail support structure 11, and can position the handrail 52 so that it will not sway left and right, maintain the stability of the handrail 5, and is not easily deformed when bearing weight.

[0044] The support tube 111 is connected to two handles 114 arranged on the left and right. The two handles 114 are mainly for the convenience of the user. When the user needs to stand up or lift his / her buttocks, he / she can hold the handles 114 to help the user's arms to support his / her body. In addition, the handles 114 are also covered with anti-slip grip sleeves 115, which also have an anti-slip effect.

[0045] The support armrest 5 has a "U" shaped structure, including a middle section 51 and two armrests 52. The two armrests 52 are symmetrically connected to both ends of the middle section 51. The seat cushion 6 is connected to the two armrests 52. The middle section 51 is rotatably connected to the rear side of the movable end of the lifting column 4 through the tube clamp 53, and the two armrests 52 are flipped back and forth between the unfolded position and the retracted position.

[0046] This structure allows the support armrest 5 to fold, and when stored, it can be flipped backward toward the rear of the lifting column 4, which can reduce the lateral space occupied. When unfolded for use, the armrest support structure 11 can support the support armrest 5, so that the support armrest 5 maintains a lateral state relative to the lifting column 4. Moreover, the support armrest 5 has sufficient strength to support the user. The "U"-shaped support armrest 5 is simple in overall design and occupies little space when folded. The armrest 52 can also support the seat cushion 6 while maintaining the function of the armrest.

[0047] The support armrest 5 is fitted with several elastic armrest gloves 54. The elastic armrest gloves 54 are mainly fitted on the support armrest 5 except for the connection positions of the tube clamp 53, the tube clamp 112, and the lock 82. The elastic armrest gloves 54 on the middle section 51 play an anti-slip role when the caregiver pushes the transfer cart, while the elastic armrest gloves 54 on the handrail 52 can insulate the cold metal material when the user's arm is placed on the support armrest 5, and the soft elastic armrest gloves 54 improve the comfort of the handrest.

[0048] The lifting column 4 includes a fixed column 41, a movable column 42, and a push rod body 43 with a motor. The fixed column 41 is vertically fixed on the base frame 9. The movable column 42 is sleeved on the fixed column 41. The support handrail 5 is connected to the top of the movable column 42. The push rod body 43 is vertically arranged inside the movable column 42, and its telescopic push rod is connected to the bottom end of the fixed column 41.

[0049] The base frame 9 includes a base 2 and two support legs 3; each support leg 3 includes a rear support section 31 and a front support section 32. The rear support section 31 is connected to the outside of the base 2, and the front support section 32 is rotatably connected to the front end of the rear support section 31 and can be folded inward to the front of the base 2. The universal casters 10 are connected to the outer ends of the rear support section 31 and the front support section 32.

[0050] The support legs 3 and support handles 5 in this transfer cart can be folded for storage (e.g., Figure 2 As shown), the volume is further reduced when stored, and the components are no longer scattered when stored. It can also quickly switch between the storage state and the use state, eliminating the need to install the support legs 3 and / or support armrests 5 every time it is reused, thus improving the efficiency of use and making the operation simple and convenient.

[0051] Another point is that after the transfer cart is folded, the four casters 6 still remain in contact with the ground, maintaining relatively parallel support points, so that the transfer cart can still stand upright when folded, reducing the space occupied when storing.

[0052] The rear support section 31 is provided with a pipe connector 311 at its front end, and the front support section 32 is provided with a second pipe fork 321 at its rear end. The second pipe fork 321 is rotatably connected to the pipe connector 311 through a hinge shaft 33, so that the two front support sections 32 are folded in front of the base 2 respectively. In this embodiment, the front end of the rear support section 31 is positioned relative to the base, and the two front support sections 32 have pipe connectors 311 at different positions with different lengths. After the two front support sections 32 are folded inward by 90°, they can be folded back and forth on the front side of the base 2. After folding, they remain on the same horizontal plane and do not interfere with each other, keeping the folded state compact and saving space.

[0053] In addition, the rear support section 31 includes an outer tube and an inner tube. The outer tube is sleeved outside the inner tube, and at least one end of the inner tube extends out of the outer tube, with the extended portion forming a pipe connector 311. Therefore, when the front support section 32 is unfolded relative to the rear support section 31, the front support section 32 can maintain the same pipe diameter as the outer tube, making the support leg 3 more consistent.

[0054] The upper part of the second pipe fork 321 is provided with a movable locking structure. When the front support section 32 is unfolded relative to the rear support section 31, the movable locking structure locks with the pipe connector 311. The movable locking structure keeps the front support section 32 in a relative position with the rear support section 31 when the front support section 32 is unfolded.

[0055] Specifically, the active locking structure includes a hexagonal head 34, with an external threaded sleeve 341 at the bottom of the hexagonal head 34 and a lower clutch part 342 at the top of the hexagonal head 34. The upper part of the second pipe fork 321 has a threaded hole 322 that connects to the external threaded sleeve 341. It also includes a manual knob 35, the bottom of which is provided with a pin 351 that passes through the hexagonal head 34 and the external threaded sleeve 341, and an upper clutch part 352 that cooperates with the lower clutch part 342. The pipe connector 311 has a pin hole that cooperates with the pin 351. The pin hole includes a first pin hole 312 and a second pin hole 313 corresponding to the unfolded position and the folded position of the front support section 32. During installation, the hexagonal head 34 is screwed into the threaded hole 322 through the external threaded sleeve 341, thereby fixing it to the second pipe fork 321. The hexagonal head 34 can be screwed in using a tool for better tightening. Alternatively, after the manual knob 35 is coupled with the lower clutch 342 through the upper clutch 352, the manual knob 35 can be used to drive the hexagonal head 34 to rotate synchronously, so that the external threaded sleeve 341 can be screwed into the threaded hole 322. When the current support section 32 is unfolded, the user can use the manual knob 35 to pull out the pin 351. After the pin 351 is aligned with the first pin hole 312, the user can then control the manual knob 35 to insert the pin 351 into the first pin hole 312 to complete the unfolding and locking. Conversely, when the current support section 32 is folded, the user can use the manual knob 35 to pull out the pin 351 from the first pin hole 312 to unlock it. Then, the user can fold the front support section 32 inward until the pin 351 is aligned with the second pin hole 313. Finally, the user can control the manual knob 35 to insert the pin 351 into the second pin hole 313 to complete the folding and locking.

[0056] The rear ends of the two support legs 3 are rotatably connected to the outside of the base 2. The rear side of the base 2 is provided with an external support synchronization mechanism 12, which is connected to the rear ends of the two support legs 3. The two support legs 3 are driven to switch between the external support position and the inward position through the external support synchronization mechanism 12.

[0057] During use, the support legs 3 can be extended outward in a figure-eight shape under the drive of the external support synchronization mechanism 12, thereby increasing the support area to cope with the tilting of the transfer vehicle due to the shift of the center of gravity caused by the user's body tilting (for stroke patients with hemiplegia).

[0058] The external support synchronization mechanism 12 mainly includes a rotating plate 121, a left push rod 122, and a right push rod 123. The rotating plate 121 is rotatably connected to the central axis position on the rear side of the base 2. One end of the left push rod 122 and the right push rod 123 are respectively hinged to the left or right end of the rotating plate 121 through a universal joint structure. The other end of the left push rod 122 and the right push rod 123 are respectively hinged to the inner rear end of the two support legs 3 through a universal joint structure. The universal joint structure at both ends enables the left push rod 122 or the right push rod 123 to move left and right, up and down, and forward and backward at the same time.

[0059] One end of the rotating plate 121 extends along its length direction with a first power arm 1211, and the arm end of the first power arm 1211 is equipped with an inward foot pedal 124. The other end of the rotating plate 121 extends along its included angle direction with a second power arm 1212, and the arm end of the second power arm 1212 is equipped with an outward support foot pedal 125.

[0060] Based on the above structure, the method of using the frame stabilization structure is as follows: In the initial state, such as Figure 9 As shown, the rotating plate 121 is placed horizontally. At this time, the left push rod 122 and the right push rod 123 are in the outward pushing position, and the two support legs 3 are in the inward retracting position and are arranged parallel to each other. When the caregiver needs to extend the support leg 3, the caregiver steps on the outer support foot pedal 125, thereby driving the rotating plate 121 to rotate to a vertical position. At this time, the left push rod 122 and the right push rod 123 are used to pull the rear end of the support leg 3 inward, thereby extending the support leg 3 to the outer support position (e.g., Figure 10 (As shown), conversely, when the caregiver needs to retract the support leg 3, they only need to step on the inward foot pedal 124 to reverse the movement of the above structure, thereby restoring it to its initial state. The base 2 has a rotation limiting part on the rear side corresponding to the first power arm 1211 and the second power arm 1212. The first power arm 1211 and the second power arm 1212 are provided with limiting mating parts that cooperate with the corresponding rotation limiting parts. The rotation limiting parts and the limiting mating parts mainly limit the first power arm 1211 and the second power arm 1212, thereby controlling the rotation amplitude of the rotating plate 121.

[0061] The rotation limiting part includes a limiting shaft 1261 fixed on the base and an elastic buffer sleeve 1262 sleeved on the outer end of the limiting shaft 1261. The limiting mating part includes a positioning recess 1263 formed on the bottom edge of the first power arm 1211 and the second power arm 1212. The positioning recess 1263 is engaged with the elastic buffer sleeve 1262. The elastic buffer sleeve 1262 can buffer the impact force of the first power arm 1211 or the second power arm 1212 on the limiting shaft 1261, reduce the collision sound generated when touching, and improve the service life of the limiting shaft 1261.

[0062] The base 2 is provided with a first tube fork 21 on the outside. A C-shaped support clip 22 is fixedly connected inside the first tube fork 21. The support leg 3 is rotatably connected inside the C-shaped support clip 22 through a rotating shaft 23. The C-shaped support clip 22 can improve the strength of the first tube fork 21 and prevent the first tube fork 21 from deforming.

[0063] The C-type support clamp 22 includes a support plate 221 placed on the upper and lower surfaces of the support frame 3 and a vertical support plate 222 connected between the two support plates 221.

[0064] The maximum opening angle Θ of the support leg 3 between the outward and inward positions is 15°-25°; the opening angle of the support leg 3 within this reasonable range can ensure that the support area is increased while maintaining the front and rear support stability.

[0065] The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
