Description
Technical Field
[0001] The utility model relates to the technical field of transfer machines, in particular to a seat rotating device for a transfer machine and the transfer machine. Background Art
[0002] A transfer machine is a device specially designed to assist disabled people in the rehabilitation and nursing industry. This type of transfer machine is usually designed to help people with limited mobility move from one position to another, making the process safer and more efficient, such as moving to the bathroom to use the toilet, moving to the dining table to eat, etc. For elderly people with limited mobility, disabled people, or other groups that require special care, transfer machines provide a safe way to reduce the workload of caregivers.
[0003] At present, there are three types of lifts on the market: 180-degree opening and closing seat, back-carrying type and sling type. The common feature of the three lifts is that the wheel frame can be inserted under the bed to realize the use process. The 180-degree opening and closing seat of the lift is to solve the problem that the seat does not affect the lift close to the bed. When the user sits on the bed, the lift seat opens close to the bed and closes the seat under the user's buttocks, so that the user can move while sitting on the seat. This type of lift will have some inconveniences in the following processes. When the user cannot sit steadily or when the user sits on the air bed, the seat cannot be closed under the user's buttocks. When putting on and taking off pants in the toilet, the two pillars in front of the seat will increase the difficulty of the caregiver to lift up. In addition, there is a hole in the middle of the seat, and the user is less comfortable sitting on it for a long time. In addition, the two pillars in front of the seat will prevent the user from getting close to the sink and the table to reach the optimal distance when brushing teeth, washing face and eating. When the user needs to get on the car, the lift seat cannot be opened, and the above-mentioned purpose of shifting cannot be achieved. The back-carrying transfer machine is suitable for short-term lifting of users. It is more convenient to put on and take off pants when going to the toilet, and the user can be lifted to the car seat. However, the disadvantage is that there is no seat, which is not suitable for users with weak upper limbs. The safety performance is not good, and long-term use requires the use of a wheelchair. The sling transfer machine can lift and transfer users who cannot sit steadily, but it cannot assist with toileting, eating, etc.
[0004] Therefore, in order to move the transfer machine closer to the bedside and solve the problem of user comfort while achieving the optimal distance when brushing teeth, washing face, and eating, it is necessary to provide a seat rotation device for a transfer machine to solve the above problems, further improve the quality of life of disabled people, and enable them to live more comfortably.

[0032] Example 1
[0033] like Figure 1 As shown, the utility model provides a seat rotating device for a transfer machine. The figure shows the structure of a part of the transfer machine.
[0034] The structure of the seat rotating device includes: a rotating frame assembly 2, which is arranged on a mobile base 1. The mobile base 1 is used to support and move the transfer machine, including a wheel frame 11 and a universal wheel 12 arranged below the wheel frame 11. In this embodiment, the wheel frame 11 is a door-shaped structure, having two side edges arranged oppositely and a crossbeam structure connecting the two side edges, but is not limited to this structure in actual application.
[0035] Rotating frame assembly 2 (such as Figure 4 Specifically, it includes a telescopic frame and an auxiliary support assembly 25 arranged on the frame. The frame of the rotating frame assembly 2 includes a main frame 21 and a telescopic frame 22. The main frame 21 and the telescopic frame 22 are arranged in a telescopic manner to form a telescopic structure.
[0036] One end of the telescopic frame 22 is rotatably fixed to one side of the wheel frame 11 through a positioning pin 23, and the rotating frame assembly 2 rotates a certain angle around the positioning pin 23, that is, Figure 4 One end of the main frame body 21 is fixed to the other side of the wheel frame 11 by means of a positioning pin 24 with a spirally tightened structure (such as Figure 1 As shown in the figure, when in use, the locking or loosening is achieved by plugging and pulling out and tightening the positioning pin 24. The positioning pin 24 matches the positioning hole on the wheel frame 11. After tightening, it is unlocked by pulling it out, and it is inserted and tightened to prevent loosening. Correspondingly, there is also a corresponding positioning hole 28 on the wheel frame 11 under the positioning pin 1 23. The function of the two positioning holes is to fix the rotating frame assembly 2. At the same time, the rotating frame assembly 2 can be swapped between the left and right fixed ends according to the user's habits or usage scenarios, that is, one side of the positioning pin 24 is swapped and fixed to the side of the positioning pin 1 23, and the installation is very flexible.
[0037] like Figure 2 and Figure 3 As shown, the auxiliary support assembly 25 includes a limit pin 251, a pull rod 257, a slide rail 255 and a slider 256. The slide rail 255 is arranged on the main frame body 21 near the locking end. The limit pin 251 is arranged on the slider 256. The slider 256 can move in the slide rail 255. The auxiliary wheel bracket 253 is hinged with the pull rod 257. One end of the pull rod 257 is connected to the limit pin 251. The other end of the auxiliary wheel bracket 253 is connected to the auxiliary wheel 254. When the limit pin 251 is pulled to drive the slider 256 to move toward the locking end, until the auxiliary wheel bracket 253 drives the auxiliary wheel 254 to support the ground, that is, Figure 3 In the state shown, the auxiliary wheel bracket 253 is perpendicular to the ground, and the auxiliary support component 25 supports the rotating frame assembly 2 to maintain the height when locked. At this time, the limit pin 251 is automatically locked at the preset position. If it needs to be returned to its original position, pull the limit pin 251 back to the locking end and move it to the initial position to automatically lock it.
[0038] The auxiliary support assembly 25 further includes a limit screw 252, which is disposed on one side of the slider 256 close to the locking end. When the auxiliary wheel 254 supports the ground, the limit screw 252 penetrates below the pin surface of the second positioning pin 24 to limit the descent of the second positioning pin 24. Figure 3 As shown, when the locking connection end of the rotating frame assembly 2 is unlocked, the positioning pin 24 is pulled out. Under the restriction of the limit screw 252, the positioning pin 24 cannot fall. At this time, the rotating frame assembly 2 can be rotated freely, and the jamming phenomenon caused by the falling of the positioning pin 24 is effectively prevented; when the seat is turned back to the use state and the auxiliary wheel 254 is retracted, the positioning pin 24 is inserted back into the hole and tightened to ensure the stability and safety of the seat.
[0039] After unlocking, the rotating frame assembly 2 rotates along the rotating axis of the rotating end (with the positioning pin 23 as the axis), and the seat can be rotated to a preset position through the length of the frame, such as Figure 5 As shown, this is the first technical means of the utility model that can adjust the overall rotation direction of the seat.
[0040] like Figure 3 As shown, a seat lifting assembly 26 is arranged on the frame, and the seat lifting assembly 26 includes a seat load-bearing seat 261 connected to the seat assembly 3 at the upper part, an adjustment rod 262 for adjusting the lifting, and a lifting cylinder.
[0041] The adjusting rod 262 is connected to a connecting plate 263, and a positioning pin 3 264 is provided at the lower end of the connecting plate 263. The positioning pin 3 264 matches the long hole 266 on the cover 265 of the seat lifting assembly 26, and is used to rotate and adjust the front and rear positions of the seat. A plurality of long holes 266 can be provided on the circumference of the cover 265 to achieve adjustment of the seat in different directions. Lifting the adjusting rod 262 drives the connecting plate 263 to lift, thereby removing the positioning pin 3 264 from the long hole 266. At this time, the seat can be rotated. When it is adjusted to a suitable direction, the adjusting rod 262 is dropped, so that the positioning pin 3 264 falls into the long hole 266 on the same side (such as Figure 5 As shown in the figure, the orientation of the seat is positioned, which is the second technical means of the present invention that can adjust the orientation of the seat circumferentially.
[0042] As an embodiment of the utility model, taking into account the discomfort of disabled people sitting for a long time, the seat assembly 3 is configured to include a seat seat 31 and a bedpan bracket 33 arranged below the seat seat 31 and connected to the seat lifting assembly 26, and the seat seat 31 is provided with a pull-out plate 32 matching the bedpan 34.
[0043] Example 2
[0044] like Figure 6 and Figure 7 As shown, different from Example 1, the rotating end of the rotating frame assembly 2 is in the form of a connecting rod structure 27. Specifically, the frame body of the rotating frame assembly 2 includes a main frame body 21 and a connecting rod structure 27, and the connecting rod structure 27 includes a first connecting rod 271 with one end fixed to one side of the wheel frame 11 by a positioning pin 23 and a second connecting rod 272 fixed to the end of the main frame body 21. The first connecting rod 271 and the second connecting rod 272 are connected by a connecting pin 273 to form a structure that can increase the length of the rotating arm of the main frame body 21. The connecting pin in the connecting rod structure can realize the steering of the seat and the structure is durable and not easy to damage; the rotating frame assembly 2 rotates a certain angle with the positioning pin 23 as the axis; the other end of the main frame body 21 is locked and fixed to the other side of the wheel frame 11 by a positioning pin 24, and the locking or loosening is achieved by plugging and pulling and tightening the positioning pin 24.
[0045] When the utility model is in use, the seat can rotate within a certain range, and can be extended and retracted in the form of a telescopic structure when necessary. For example, when operating at the bedside, when using the transfer machine to lift the user from the bed to the sitting position, or from the bedside to the seat, the transfer machine must be close to the bedside so that the upper lifting rod is above the user's body. If the seat cannot be rotated and moved out, it will affect the transfer machine's proximity to the bedside or other areas that need to be approached. The utility model pulls out the positioning pin 24, and the auxiliary support assembly 25 can support the seat to rotate sideways and rearwards along the rotation axis, so that the transfer machine can be close to the bedside or other areas that need to be approached.
[0046] In addition, the utility model also provides a transfer machine, which adopts the above-mentioned seat rotation device, such as Figure 1 The armrest lifting mechanism / rotation mechanism on the main column 4 is not shown, and the movable base can also be set to a structure that can pass through a threshold, which is also not shown. The utility model is not limited to a certain structural form of the transfer machine, but mainly highlights that in specific usage scenarios, it can better fit the bedside, poolside, or dining tableside, etc., and adjust the seat orientation at multiple angles and degrees of freedom to improve the user's comfort.
[0047] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, a person skilled in the art should understand that any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
