[0041] Example

[0042] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this embodiment provides a transfer machine, including a base frame 10, a base 11, a lifting frame 12, and a chair frame 13. Multiple first casters 101 are provided on the bottom surface of the base frame 10; one end of the base 11 is hinged to the base frame 10, and multiple second casters 111 are provided on the bottom surface of the base 11; the lifting frame 12 is slidably and vertically mounted on the base frame 10, and a power unit 102 is provided on the base frame 10 to drive the lifting frame 12 to rise or fall; one end of the chair frame 13 is hinged to the lifting frame 12, and the lifting frame 12 is provided with at least one lap seat 121 to limit the rotation of the chair frame 13. The chair frame 13 laps on the lap seat 121, thereby restricting the downward rotation of the chair frame 13 to ensure the stability of the chair frame 13 during use. The power unit 102 is a hydraulic pump or an electric push rod. In an optional embodiment, the power unit 102 is a CBT-304 hydraulic oil pump.

[0043] Specifically, the first caster 101 and the second caster 111 can be self-locking swivel casters, allowing caregivers to move the transfer machine in multiple directions, assisting people with mobility impairments or those requiring assisted movement to complete sitting-to-standing transfers. To adapt to beds or seats of different heights and improve user comfort, the transfer machine can adjust the height of the lifting frame 12 via the power unit 102, thereby adjusting the height of the seat 14. Specifically, the seat 14 is detachably mounted on the chair frame 13 (the seat 14 can be hung, fitted, or fixed to the chair frame 13 using straps). The chair frame 13 is mounted on the lifting frame 12. Therefore, by raising or lowering the lifting frame 12 via the power unit 102, the height of the seat 14 can be adjusted. The power unit 102 can be a foot pedal switch, allowing for raising and lowering by stepping on the switch, making operation more convenient.

[0044] When not in use, the base 11 can rotate around its hinge point with the base frame 10, thereby folding it together with the base frame 10. The seat 14 can be removed from the chair frame 13, and the chair frame 13 can be rotated around its hinge point with the lifting frame 12, so that the chair frame 13 and the lifting frame 12 can be folded together. In this way, the transfer machine can be folded into a compact form, which is convenient for storage in environments with limited space and suitable for occasions that require frequent moving.

[0045] like Figure 5 As shown, in this embodiment, the base frame 10 is provided with at least one guide rod 103, and the lifting frame 12 is provided with a sliding rod 122 that is slidably connected to the guide rod 103. Specifically, the base frame 10 may include two symmetrically arranged sleeves 106, and two guide rods 103 may be provided. The guide rods 103 are vertically arranged inside the sleeves 106, and a first crossbar 107 is provided between the two sleeves 106 for connection (the first crossbar 107 can also serve as a footrest for the user to place their feet). At the same time, two sliding rods 122 are provided on the lifting frame 12 to be appropriately connected to the guide rods 103, and a second crossbar 125 is provided between the two sliding rods 122 for connection (the second crossbar 125 can also serve as a handrail for caregivers to push the transfer machine or to assist in supporting the user to stand). The fixed end of the power unit 102 can be bolted to the middle of the first crossbar 107, and the driving end of the power unit 102 can be bolted to the middle of the second crossbar 125, forming a design effect of lifting driven by the power unit 102.

[0046] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the base 11 includes two support legs 112; the bottom of the base frame 10 is provided with a connecting section 104 that is hinged to the axis of the support leg 112, and the connecting section 104 is also provided with a pin 1041 for restricting the rotation of the support leg 112.

[0047] Specifically, the support leg 112 can be hinged to the connecting section 104 of the base frame 10 via the connecting shaft 1043. During use, the support leg 112 is connected to the connecting section 104 via a pin 1041, thereby restricting the rotation of the support leg 112 and ensuring the stability of the base 11 during use. The pin 1041 can be a U-shaped pin. When not in use, the pin 1041 can be removed, allowing the support leg 112 to rotate around the connecting shaft 1043, thus achieving the effect of folding the support leg 112 and the base frame 10 together.

[0048] like Figure 4 As shown, in this embodiment, the support leg 112 is provided with a limiting hole 1121, and the connecting section 104 is provided with a spring pin 1042 that engages or disengages with the limiting hole 1121. The spring pin 1042 can be a pull-ring type indexing plunger with a built-in spring, optionally a PMX-R indexing plunger. By pulling the pull ring, the pin can be pulled out or inserted, thereby engaging or disengaging with the limiting hole 1121. To ensure that the support leg 112 does not loosen after folding, the spring pin 1042 can engage with the limiting hole 1121 after folding, thereby fixing the folded support leg 112 and connecting section 104 together and ensuring the stability of folding.

[0049] like Figure 1 , Figure 3 and Figure 5 As shown, in this embodiment, a convex shaft 105 is provided in the middle of the base frame 10, and a first caster 101 is provided on the bottom surface of the convex shaft 105. The diameter of the first caster 101 is larger than the diameter of the second caster 111, and the bottom surfaces of the first caster 101 and the second caster 111 are on the same horizontal plane. The larger diameter of the first caster 101 can serve as a support point for the main load-bearing and movement direction control; the smaller diameter of the second caster 111 can reduce the overall turning radius, making the transfer machine more flexible and easier to operate, and lowering the height of the base 11 so that the base 11 can be inserted into the narrow gaps of beds or seats.

[0050] like Figure 1 and Figure 3 As shown, in this embodiment, the lifting frame 12 is provided with a rotating handrail 123. Specifically, there are two rotating handrails 123, which are symmetrically arranged on both sides of the lifting frame 12. The rotating handrails 123 can be adjusted in position according to different scenarios. For example, when moving the transfer machine, they can be folded or rotated to the side to reduce space occupation. When support is needed, the rotating handrails 123 can be rotated to a suitable position to provide a stable support point for the user.

[0051] like Figure 1As shown, in this embodiment, the lifting frame 12 is provided with at least one mounting cylinder 124. The mounting cylinder 124 can be used to install a boom and a sling. The sling can assist users with mobility impairments to stand up, so as to facilitate the transfer of users with mobility impairments from the bed to a wheelchair, sofa or other seat. The sling can also be used to assist users with mobility impairments to perform standing training.

[0052] like Figure 3 As shown, in this embodiment, the chair frame 13 includes two rotating arms 131 and a backrest 132. One end of the rotating arm 131 is hinged to the lifting frame 12, and the other end of the rotating arm 131 is provided with a connector tube 1311. The backrest 132 is inserted into or detached from the connector tube 1311. When not in use, the backrest 132 can be removed from the rotating arm 131, thereby folding the rotating arm 131, further reducing the volume of the transfer machine after folding, making it easy to store in a small space or to transport.

[0053] like Figure 1 and Figure 3 As shown, in this embodiment, the rotating arm 131 is provided with a plurality of lugs 1312 for mounting the seat 14; the connecting seat 121 is provided with a limiting groove 1211 for engaging or disengaging with the rotating arm 131.

[0054] Specifically, the seat 14 can be a hanging chair, which is hung on the rotating arm 131 via the hanging lug 1312. It can be removed when not in use, making installation and disassembly convenient. The rotating arm 131 can be a round rod structure, which engages with the limiting groove 1211 of the connecting seat 121 to restrict its rotation, which is the working state; it rotates around the hinge point to separate from the limiting groove 1211 of the connecting seat 121, and then closes with the lifting frame 12, which is the folded state.

[0055] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
