Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a transfer frame. Background Technology

[0002] In today's society, the proportion of the elderly population is increasing, and the number of patients with mobility impairments due to accidents or illnesses is also very large. These patients often face significant difficulties in completing daily transfers and typically require the assistance of a transfer vehicle. Transfer vehicles are used by assistive staff to move patients from wheelchairs to other locations (such as beds, sofas, toilets, car seats, etc.). Their main function is to ensure a safe, effortless, and efficient transfer process while minimizing the risk of injury to both the patient and assistive staff.

[0003] Existing transfer frames have relatively complex structures with numerous adjustable features. Typically, these frames consist of two opposing supports with casters at the bottom, connected by a linkage. Knee supports are mounted on the linkage, and each support has an armrest. The distance between the supports, as well as the height of the armrests and knee supports, needs to be adjusted according to the user's height, making pre-use adjustments cumbersome. Furthermore, these transfer frames are quite large, requiring ample space for use, and also occupy a significant amount of space when not in use.

[0004] The technical problem to be solved by this utility model is: how to solve the problems of complex structure, bulky size and inconvenient adjustment of existing transfer racks. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a transfer rack with a simple and compact structure and convenient use.

[0006] The technical solution adopted by this utility model is as follows: a transfer frame, including a base and a support. The base includes a fixed plate and a rotating plate. The rotating plate is located at the bottom of the fixed plate and is rotatably connected to the fixed plate. The fixed plate is also provided with wheels. The support includes a first connecting rod, a second connecting rod, a knee support member, and a handrail. One end of the first connecting rod is fixedly connected to the fixed plate, and the other end is slidably connected to the second connecting rod. A locking member is provided between the first connecting rod and the second connecting rod. The knee support member is installed on the first connecting rod, and the handrail is installed on the second connecting rod.

[0007] The transfer frame of this application, by setting a first connecting rod and a second connecting rod that can slide relative to each other, and setting the handrail on the second connecting rod, allows the height of the handrail to be adjusted according to the user's height, making the adjustment convenient and quick. The main body of the transfer frame consists of a base and a support, making the overall structure simpler and more compact. The relatively rotatable fixed plate and rotating plate work together to enable the support to change direction in place, and the fixed plate is equipped with wheels that are easy to move, making it convenient to transfer users.

[0008] In some embodiments, the knee support is provided with a sleeve and a locking member. The sleeve slides with the outer surface of the first connecting rod. One side of the sleeve is provided with a telescopic opening. The locking member is provided at the telescopic opening of the sleeve and is used to adjust the width of the telescopic opening.

[0009] By adopting the above technical solution and setting up a sleeve and locking device, the height of the knee support can be adjusted according to the user's height, making the adjustment more convenient and the versatility better.

[0010] In some embodiments, the knee support also includes a frame and a knee pad, the frame being connected to a sleeve, and the knee pad being mounted on the frame.

[0011] Using the above technical solution, the knee pad can provide support for the user's knees when the user stands up from the wheelchair, and the soft material can reduce the feeling of pressure and improve comfort.

[0012] In some embodiments, the first connecting rod has an inner hole that slides with the second connecting rod, the locking member is threadedly connected to the first connecting rod, and one end of the locking member extends into the inner hole.

[0013] By adopting the above technical solution, the first connecting rod and the second connecting rod are slidably connected to achieve adjustment of their total length, which is more convenient and aesthetically pleasing. The depth of the second connecting rod inserted into the first connecting rod is locked by the locking component, thereby locking the total length of the two rods, making the structure more reliable.

[0014] In some embodiments, the outer surface of the second connecting rod is provided with an anti-rotation surface, and the inner hole shape of the first connecting rod matches the outer contour of the second connecting rod.

[0015] By adopting the above technical solution, the anti-rotation surface can prevent the second connecting rod from rotating relative to the first connecting rod, making the transfer frame safer and more reliable during use.

[0016] In some embodiments, the base also includes a pad disposed between the fixed disk and the rotating disk, and the fixed disk and / or the rotating disk are provided with grooves for receiving the pad.

[0017] By adopting the above technical solution and setting a pad, the friction between the rotating disk and the fixed disk during relative rotation can be reduced, making the rotating disk rotate more smoothly and improving the durability of the base.

[0018] In some implementations, when the base is placed horizontally, the bottom of the wheel is higher than the height of the rotating disk.

[0019] By adopting the above technical solution, the transfer frame can be prevented from slipping during the process of transferring the user from the wheelchair to the transfer frame, thus improving the reliability of the transfer frame.

[0020] In some implementations, one end of the first connecting rod is connected to the fixed plate, and the other end extends obliquely toward the wheel.

[0021] By adopting the above technical solution, the first connecting rod and the fixed plate are inclined, which makes it easier for the user to stand on the transfer frame and lean against the support, thus improving comfort. Moreover, the first connecting rod is inclined towards the wheels, so that when moving the transfer frame, the wheels can be made to contact the ground by slightly tilting the transfer frame, which facilitates the pushing of the transfer frame.

[0022] In some embodiments, a wheel frame is provided on the fixed disk, one end of which is connected to the fixed disk and the other end extends toward the edge of the fixed disk, and the wheel is rotatably connected to the end of the wheel frame away from the fixed disk.

[0023] By adopting the above technical solution, the wheel frame can be set up to facilitate the installation of wheels, and at the same time, it can ensure that the wheels do not contact the ground when the base is placed horizontally, which is safer and more reliable.

[0024] In some implementations, the top of the mounting plate is provided with anti-slip texture.

[0025] By adopting the above technical solution, the anti-slip texture can increase the friction between the fixed plate and the user's foot, thus playing an anti-slip role. Attached Figure Description

[0034] Please see Figures 1 to 4A preferred embodiment of the present invention provides a transfer frame 100, comprising a base 10 and a support 20. The base 10 includes a fixed plate 11 and a rotating plate 12. The rotating plate 12 is disposed at the bottom of the fixed plate 11 and is rotatably connected to the fixed plate 11. The fixed plate 11 is also provided with wheels 13. The support 20 includes a first connecting rod 21, a second connecting rod 22, a knee support member 23, and a handrail 24. One end of the first connecting rod 21 is fixedly connected to the fixed plate 11, and the other end is slidably connected to the second connecting rod 22. A locking member 25 is provided between the first connecting rod 21 and the second connecting rod 22. The knee support member 23 is installed on the first connecting rod 21, and the handrail 24 is installed on the second connecting rod 22. The transfer frame 100 of this application, by setting a first connecting rod 21 and a second connecting rod 22 that can slide relative to each other, and setting a handrail 24 on the second connecting rod 22, allows the height of the handrail 24 to be adjusted according to the user's height, making adjustment convenient and quick. The main body of the transfer frame 100 consists of a base 10 and a support 20, making the overall structure simpler and more compact. The relatively rotatable fixed plate 11 and rotating plate 12 cooperate to enable the support 20 to change direction in place, and the fixed plate 11 is equipped with wheels 13 for easy movement, making it convenient to transfer users.

[0035] like Figure 3 As shown, the knee support component 23 is equipped with a sleeve 231 and a locking component 232. The sleeve 231 slides on the outer surface of the first connecting rod 21. A telescopic opening is provided on one side of the sleeve 231, and the locking component 232 is located at the telescopic opening of the sleeve 231 to adjust the width of the opening. By using the sleeve 231 and the locking component 232, the height of the knee support component 23 can be adjusted according to the user's height, making adjustment more convenient and improving versatility.

[0036] In this embodiment, the locking element 232 is a screw that passes through both sides of the telescopic opening. A nut is threadedly connected to one end of the screw. By tightening or loosening the screw, the sleeve 231 can be locked or released, thereby enabling rapid adjustment of the position of the knee support 23. Preferably, to facilitate turning the screw, a knob is provided at the end of the screw away from the nut.

[0037] In other embodiments, the locking member 232 can also be configured as a pull rod, which passes through both sides of the telescopic opening. An anti-disengagement component is provided at one end of the pull rod, and a handle for pulling the pull rod is provided at the other end, providing the means to tighten or loosen the pull rod, thereby locking and loosening the sleeve 231.

[0038] Furthermore, the knee support component 23 also includes a frame 233 and a knee pad 234. The frame 233 is connected to the rod sleeve 231, and the knee pad 234 is installed on the frame 233. The knee pad 234 can provide support for the user's knees when the user stands up from the wheelchair, and the soft material can reduce pressure and improve comfort.

[0039] Preferably, the knee pad 234 is made of a soft material.

[0040] Please refer to the following: Figure 3 In this embodiment, the first connecting rod 21 has an inner hole that slides with the second connecting rod 22. The locking member 25 is threadedly connected to the first connecting rod 21, and one end of the locking member 25 extends into the inner hole. The first connecting rod 21 and the second connecting rod 22 are slidably connected to each other to adjust their total length, which is more convenient and aesthetically pleasing. The locking member 25 locks the depth of the second connecting rod 22 inserted into the first connecting rod 21, thereby locking their total length. The structure is more reliable and can achieve stepless length adjustment with a wider adjustable range.

[0041] In other embodiments, the locking member 25 can also be configured as a retractable ball or spring. The locking member 25 is installed on the second connecting rod 22. A plurality of limiting holes corresponding to the locking member 25 are provided at intervals along the length extension direction on the first connecting rod 21. By pressing the locking member 25 out of the limiting hole, the second connecting rod 22 can be extended beyond the length of the first connecting rod 21. When the locking member 25 extends out of the limiting hole, the second connecting rod 22 can be locked beyond the length of the first connecting rod 21.

[0042] In one embodiment, the outer surface of the second connecting rod 22 is provided with an anti-rotation surface 221, and the inner hole shape of the first connecting rod 21 matches the outer contour of the second connecting rod 22. The anti-rotation surface 221 can prevent the second connecting rod 22 from rotating relative to the first connecting rod 21, making the transfer frame 100 safer and more reliable during use.

[0043] In this embodiment, the second connecting rod 22 is a flat rod. In other embodiments, the second connecting rod 22 can also be a round rod. However, in order to prevent the second connecting rod 22 from rotating relative to the first connecting rod 21, a plane to prevent rotation can be provided on the surface of the round rod. In other embodiments, the second connecting rod 22 can also adopt other polygonal prism structures.

[0044] Preferably, in order to make the connection between the fixed disk 11 and the first connecting rod 21 more reliable, a protruding connecting sleeve is provided on the fixed disk 11, and a connecting groove corresponding to the first connecting rod 21 is provided inside the connecting sleeve. The connecting sleeve can increase the contact area between the fixed disk 11 and the first connecting rod 21, so that the connection between the fixed disk 11 and the first connecting rod 21 is tighter and more reliable.

[0045] In this embodiment, the base 10 further includes a pad 14 disposed between the fixed disk 11 and the rotating disk 12. The fixed disk 11 and / or the rotating disk 12 are provided with grooves for accommodating the pad 14. By providing the pad 14, the friction between the rotating disk 12 and the fixed disk 11 during relative rotation can be reduced, making the rotating disk 12 rotate more smoothly and improving the durability of the base 10.

[0046] To improve the reliability and safety of the transfer rack 100, such as Figure 2 As shown, when the base 10 is placed horizontally, the bottom of the wheels 13 is higher than the height of the rotating disk 12. This can prevent the transfer frame 100 from slipping during the process of transferring the user from the wheelchair to the transfer frame 100, thus improving the reliability of the transfer frame 100.

[0047] Furthermore, one end of the first connecting rod 21 is connected to the fixed plate 11, and the other end extends at an angle toward the wheel 13. The first connecting rod 21 is inclined to the fixed plate 11, which makes it easier for the user to stand on the transfer frame 100 and lean against the support 20, thus improving comfort. Moreover, the first connecting rod 21 is inclined toward the wheel 13, which means that when moving the transfer frame 100, a slight tilt of the transfer frame 100 can make the wheel 13 contact the ground, making it easier to push the transfer frame 100.

[0048] Furthermore, a wheel frame 15 is provided on the fixed plate 11. One end of the wheel frame 15 is connected to the fixed plate 11, and the other end extends towards the edge of the fixed plate 11. The wheel 13 is rotatably connected to the end of the wheel frame 15 away from the fixed plate 11. By providing the wheel frame 15, it is easy to install the wheel 13, and at the same time, it can be ensured that the wheel 13 does not contact the ground when the base 10 is placed horizontally, which is safer and more reliable.

[0049] Preferably, the top of the fixing plate 11 is provided with anti-slip texture. The anti-slip texture can increase the friction between the fixing plate 11 and the user's foot, thus playing a role in preventing slippage.

[0050] During the transfer, the assistant first adjusts the height of the armrest 24 and knee pad 23 according to the user's body size. Then, the knee pad 234 of the transfer frame 100 is oriented towards the user sitting in the wheelchair, and the transfer frame 100 is moved closer to the wheelchair. The user places their feet on the fixed plate 11, then places their knees on the knee pad 234, and then holds the armrest 24. With the help of the assistant, the user leans their body against the support 20. The assistant can adjust the direction of the support 20 as needed. When moving, the assistant only needs to tilt the transfer frame 100 slightly towards the wheels 13 so that the wheels 13 are in contact with the ground. Then, the assistant can hold the armrest 24 and move the transfer frame 100 and the user standing on the transfer frame 100 by pushing or pulling.

[0051] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
