Description

Technical Field

[0001] This utility model relates to the field of patient transfer equipment technology, specifically to a knee-mounted adjustment structure and a transfer machine. Background Technology

[0002] With the deepening of population aging, society's demand for medical care and long-term care for the elderly, especially the disabled and semi-disabled, has become extremely urgent. Transfer machines, as assistive products for elderly care, have a large market. A transfer machine is a tool for transferring patients; it can lift patients from chairs, allow caregivers to push them to the toilet and place them smoothly on the commode, and can also be used in situations requiring patient transfer, such as moving patients from chairs to dining chairs. This device typically uses an electrically driven actuator to power a robotic arm that lifts or lowers the patient.

[0003] Because users have different heights, their knee heights also vary. Currently, there are already knee-adjustable transfer machines on the market. For example, Chinese Patent Publication No. CN220778540U discloses a backrest-type transfer machine, including a knee rest, a knee rest mounting rod, a knee rest mounting tube, a knee rest adjusting bolt, and a knee rest locking nut. The knee rest mounting rod is inserted into the knee rest mounting tube, and the length of the knee rest mounting rod extending into the knee rest mounting tube is adjusted by the adjusting bolt. That is, the knee rest mounting structure in the above technical solution uses a telescopic adjustment method. However, this telescopic adjustment structure can only adjust the knee position and cannot solve the angle adjustment problem. Although the above technical solution uses a hinged connection between the knee rest mounting tube and the frame of the transfer machine, and each end of the knee rest mounting tube is equipped with a tension spring to achieve angle adjustment, this structure is generally complex. Furthermore, during use, the angle of the knee rest may change due to different forces applied by the user, meaning the knee rest angle is not fixed during use. This is not conducive to the user maintaining stability. For example, Chinese patent document CN222657368U discloses a rehabilitation transfer machine, including a knee protection device. This device comprises a knee rod and a protective pad, with the knee rod including a vertically extendable vertical rod. While this knee protection device allows adjustment of the height of the protective pad, it cannot adjust its angle. Therefore, it is necessary to develop a novel knee-supporting adjustment structure and transfer machine to solve the aforementioned problems. Utility Model Content

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0023] The transfer machine in this embodiment of the utility model can be a commercially available embracing transfer machine, and its specific structure is not described or limited. Figure 3 As shown, the transfer machine includes a frame 20 and a knee mounting adjustment structure. The knee mounting adjustment structure is mounted on the frame 20 and provides a fixed knee pad 30 for installation. This invention mainly improves the knee mounting adjustment structure of existing embracing transfer machines. Specifically, the knee mounting adjustment structure provided in this embodiment is described in [reference needed]. Figures 1 to 3The main components include a top knee mounting plate 10, a locking connector 15, and an adjusting connector 14. The top knee mounting plate 10 includes a mounting plate surface 11 for mounting and fixing the top knee soft pack 30, and two connecting plate surfaces 12 that are respectively connected to the two sides of the frame 20. That is, the top knee mounting plate 10 is a U-shaped structural component. More specifically, at least one set of mounting adjustment holes 13 is provided on any connecting plate surface 12. Each set of mounting adjustment holes 13 includes two adjusting holes and locking holes 132 at different heights, i.e., spaced apart along the height direction. The locking hole 132 is a circular hole, and the adjusting hole 131 is an arc-shaped hole formed by an arc length of a circle with the locking hole 132 as the center of rotation and a certain length as the radius. The radius and arc length of the arc-shaped hole are not particularly limited, and those skilled in the art can select and design them according to the required rotation angle in the actual design. Locking connector 15 and adjusting connector 14 are respectively connected to locking hole 132 and adjusting hole 131, and both locking connector 15 and adjusting connector 14 have locked and unlocked states. It should be noted that locking connector 15 and adjusting connector 14 are connected to one set of mounting adjustment holes 13, more specifically, one locking hole 132 and adjusting hole 131 within that set of mounting adjustment holes 13, rather than connecting adjusting connector 14 and locking connector 15 to every adjusting hole 131 and locking hole 132. In the locked state, the knee mounting plate 10 is fixed relative to the frame 20. In the unlocked state, locking connector 15 and adjusting connector 14 are connected to both the knee mounting plate 10 and the frame 20, but not in a locked state; the knee mounting plate 10 is movable relative to the frame 20. When angle adjustment is required, both locking connector 15 and adjusting connector 14 are set to the unlocked state. The knee mounting plate 10 can rotate around the locking connector 15 or locking hole 132 as the rotation center. The adjusting connector 14 can slide within the adjusting hole 131, with the two ends of the adjusting hole 131 serving as limits for angle adjustment. After adjusting to the appropriate angle, both adjusting connector 14 and locking connector 15 are locked. This allows for angle adjustment of the knee pad 30, and the position of the knee mounting plate 10 remains fixed after adjustment, resulting in a higher and more stable user experience. When height adjustment is required, simply select the appropriate height mounting adjustment hole 13 for installation; the structure is simple.

[0024] For example, in the embodiments of this utility model, such as Figure 2As shown, there are four sets of mounting adjustment holes 13, which are spaced apart along the height direction and the length direction of the knee mounting plate 10. By providing multiple sets of mounting adjustment holes 13 along the height direction, it can accommodate people with different knee heights; by providing multiple sets of mounting adjustment holes 13 along the length direction, it can accommodate people with different thigh lengths. That is, the knee mounting plate 10 of this embodiment has multiple mounting positions, with each set of mounting adjustment holes 13 serving as one mounting position. Alternatively, the number of mounting adjustment holes 13 can be other sets, such as six sets, eight sets, etc., for example, three or four sets spaced apart along the length direction of the knee mounting plate 10, and three or four sets spaced apart along the height direction of the knee mounting plate 10, etc. Regarding the number of locking holes 132 and adjustment holes 131 in each set of mounting adjustment holes 13, in addition to the exemplary one each, other numbers can be used, such as two or three each, etc.

[0025] In a preferred embodiment, such as Figure 2 As shown, in any set of mounting adjustment holes 13, adjustment hole 131 is above locking hole 132. As an alternative embodiment, adjustment hole 131 may also be below locking hole 132 (not shown).

[0026] In a preferred embodiment, in any set of mounting adjustment holes 13 of this utility model, the line connecting the centers of the adjustment hole 131 and the locking hole 132 ( Figure 2 The middle mark is L1) and the vertical line ( Figure 2 There is an angle between the two (marked as L0). Figure 2 The included angle α is not specifically limited, and can be, for example, 10°, 15°, 20°, 30°, 45°, 60°, etc. The specific design is selected based on the required adjustable angle of the top knee mounting plate 10 and to avoid interference with the frame 20. The line connecting the centers of the mounting adjustment holes 131 and locking holes 132 in all groups (i.e., each mounting position's adjustment hole 131) is parallel.

[0027] In this embodiment of the invention, the diameter of the locking hole 132 in all groups of mounting adjustment holes 13 is the same. However, in some embodiments, the length of the adjustment hole 131 in some groups of mounting adjustment holes 13 is not equal to the arc length of the adjustment hole 131 in other groups of mounting adjustment holes 13. For example, Figure 2As shown, any connecting plate surface 12 in this embodiment of the present invention is inverted L-shaped, specifically including a first connecting plate 121 and a second connecting plate 122. The first connecting plate 121 is connected to the mounting plate surface 11, and the second connecting plate 122 is away from the mounting plate surface 11. The top surfaces of the first connecting plate 121 and the second connecting plate 122 are on the same horizontal plane. The height of the second connecting plate 122 is greater than that of the first connecting plate 121, specifically, the lower end of the second connecting plate 122 extends a certain distance below the first connecting plate 121 (for example, the height of the second connecting plate 122 is twice the height of the first connecting plate 121). The first connecting plate 121 and the second connecting plate 122 are preferably integrally formed plates. Mounting adjustment holes 13 are formed on the second connecting plate 122. The length of the adjustment holes 131 formed near the first connecting plate 121 on the upper and lower parts of the second connecting plate 122, that is, the part extending to the lower end surface of the first connecting plate 121, is less than the length of the adjustment holes 131 in other mounting adjustment holes 13. As an alternative embodiment, the first connecting plate 121 can also have mounting adjustment holes 13, that is, both the first connecting plate 121 and the second connecting plate 122 have mounting adjustment holes 13. The first connecting plate 121 can have fewer mounting adjustment holes 13 to avoid interference with the frame 20 during adjustment.

[0028] In a preferred embodiment, the connecting plate 12 and the mounting plate 11 are integrally formed plates, for example, integrally bent and cut sheet metal parts. The specific process is not described or limited and is not an innovation of this utility model.

[0029] The locking connector 15 and the adjusting connector 14 are not specifically described or limited, and are simply conventional screws. As for the knee pad 30 and its connection to the mounting plate 11, as well as other structures of the transfer machine, they are not described or limited, and are not innovative points of this utility model. Please refer to the description of the applicant's previously filed patent application with patent number CN222983305U, entitled "A Foldable Transfer Machine".

[0030] In summary, the knee mounting adjustment structure of this utility model embodiment is provided with multiple sets of mounting adjustment holes 13 spaced apart along the height and length directions. Each set of mounting adjustment holes 13 includes adjustment holes 131 and locking holes 132 spaced apart along the height direction, which can realize the adjustment of the angle and height of the knee soft pack 30. The structure is simple and the position of the knee mounting plate 10 is fixed after adjustment, thereby making the user's experience higher and more stable.
