Description

Technical Field

[0001] This application relates to the field of orthopedic auxiliary medical devices, and particularly to a nursing wheelchair. Background Art

[0002] A wheelchair is a means of transportation designed for people with limited mobility, mainly used to assist them in moving and performing daily activities, which is of great significance for the travel of patients with leg fractures.

[0003] The main components of a wheelchair include a seat, wheels, a frame, footrests, and a braking system. When a wheelchair is used by a person with a leg fracture, since the patient's leg is wrapped with a bandage and the patient's leg is in a straight or slightly bent state, a leg rest is currently installed on the wheelchair to support the leg, so that the patient's leg is in a relaxed state.

[0004] The existing leg rests are fixed, and for patients with different leg lengths, some leg rests cannot provide proper support. Utility Model Content

[0005] This application provides a nursing wheelchair that can adjust the leg rest to a proper position to provide proper support for patients with different leg lengths.

[0006] This application provides a nursing wheelchair, including a bracket, a leg rest, and a locking assembly. The leg rest is installed on the bracket, and the leg rest slides along a first direction and rotates around a first circumferential direction on the bracket. The first direction is the length direction of the bracket, and the first circumferential direction is the circumferential direction of the bracket; the locking assembly connects the leg rest and the bracket and is used to lock the leg rest at a set position on the bracket.

[0007] Optionally, the leg rest includes a connecting pipe and a bracket; the connecting pipe is sleeved on the connecting pipe of the bracket, the connecting pipe slides along the first direction and rotates around the first circumferential direction, and the bracket is fixedly connected to the connecting pipe and is used to support the leg; the locking assembly connects the connecting pipe and the bracket and is used to lock the connecting pipe at a set position on the bracket.

[0008] Optionally, a plurality of locking holes are formed on the side surface of the bracket; the locking assembly includes a locking pin and an elastic member; the locking pin is slidably assembled on the connecting pipe, one end of the locking pin can slide out of the connecting pipe and extend into the locking hole, and when the connecting pin is located in the locking hole, the connecting pipe is locked to the bracket; the elastic member connects the locking pin and the connecting pipe and is used to apply pressure to the locking pin to make the locking pin have the effect of extending out of the connecting pipe or keep one end of the locking pin in the locking hole.

[0009] Optionally, the plurality of locking holes are arranged in an array along the first direction and the first circumferential direction on the bracket.

[0010] Optionally, the leg rest further includes a stabilizing pipe, the bracket is fixedly connected to the stabilizing pipe, and the stabilizing pipe is sleeved on the bracket.

[0011] Optionally, it further includes a chair frame and an angle adjustment component; wherein, the bracket is hinged to the chair frame to adjust the tilt angle of the bracket during rotation; the angle adjustment component connects the chair frame and the bracket and is used to lock the bracket at a set tilt angle.

[0012] Optionally, the angle adjustment component includes a first tube, a second tube and a fixing member; wherein, the first tube is hinged to the chair frame and the second tube is hinged to the bracket; the second tube is slidably assembled on the first tube, and the fixing member is used to lock the first tube and the second tube.

[0013] Optionally, the leg rest includes a cushion, and the thickness of the cushion is lower in the middle along the width direction than at both ends along the width direction.

[0014] In the above technical solution, by moving the leg rest in the first direction, the leg rest can be adapted to patients with different leg lengths for use, so that the leg rest can contact the patient as needed, such as contacting the calf part of the patient, meeting the use requirements of the patient.

[0015] Since the leg rest in this solution can rotate around the first circumferential direction, the surface of the leg rest for supporting the leg is no longer limited to only tilting along the first direction at a fixed angle, but can further rotate a certain angle relative to the first circumferential direction and then tilt along the left-right direction of the seat, better adapting to the leg shapes of different patients and providing more stable support for the legs of the patients.

[0016] When the connecting tube moves so that the locking pin aligns with the locking hole, the locking pin is inserted into the locking hole to achieve the locking between the connecting tube and the bracket. When it is necessary to move and adjust the position of the leg rest, an acting force is applied to the locking pin to pull the locking pin out of the locking hole, rotate the leg rest in the first direction or around the first circumferential direction, move the leg rest to a suitable position, then remove the acting force on the locking pin, and the elastic member pushes the locking pin to move through the step so that the locking pin is inserted into the locking hole.

[0017] After the patient's leg is placed on the cushion, affected by the cushion itself, the patient's leg can be placed on the leg rest more stably. The structure of the cushion increases the contact area between the leg and the cushion, further improving the stability and comfort of the patient's leg placement. Description of the Drawings

[0023] The present application will be further described in detail below with reference to the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present application will become clearer and more definite.

[0024] The special term "exemplary" here means "serving as an example, embodiment or illustration". Any embodiment described as "exemplary" here does not have to be construed as superior to or better than other embodiments. Although various aspects of the embodiments are shown in the drawings, the drawings do not have to be drawn to scale unless otherwise specified.

[0025] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0026] An embodiment of the present application discloses a nursing wheelchair. Refer to Figure 1 , the wheelchair includes a seat, wheels, a frame, footrests and a braking system. The seat is composed of a seat cushion and a backrest, and is used to provide support for the occupant. The wheels include two small wheels in the front and two large wheels in the back. The large wheels are convenient for pushing and crossing small obstacles, and the small wheels are used for steering and flexibility. The frame is the main structure of the wheelchair and is used to support the seat, wheels and other components. The footrests are located below the seat and provide support for the feet of the occupant. The braking system is used to fix the wheelchair when needed to prevent it from sliding or moving by itself.

[0027] The existing wheelchair also includes a leg rest 2 fixed on the frame. The leg rest 2 is used to support the patient's legs and relax the leg muscles. The heights of the objects using the wheelchair vary greatly. After the patient sits on the seat, the positions of the legs from the seat cushion also vary greatly. In some cases, the leg rest 2 cannot play a supporting role.

[0028] Refer to Figure 1, the nursing wheelchair disclosed in this embodiment includes a bracket 11, a leg rest 2, and a locking assembly 3. The leg rest 2 is installed on the bracket 11, and the leg rest 2 slides along the first direction and rotates around the first circumferential direction on the bracket 11, where the first direction is the length direction of the bracket 11, and the first circumferential direction is the circumferential direction of the bracket 11; the locking assembly 3 connects the leg rest 2 and the bracket 11 and is used to lock the leg rest 2 at a set position on the bracket 11.

[0029] Specifically, the bracket 11 is part of the vehicle frame. The bracket 11 is a rigid pipe fitting and serves as part of the support for the seat. The brackets 11 in this embodiment are symmetrically distributed on both the left and right sides of the wheelchair.

[0030] For ease of description, the first direction, the first circumferential direction, and the second direction are defined, where the first direction is the length direction of the bracket 11, the first circumferential direction is the circumferential direction of the bracket 11, and the second direction is the left - right direction of the seat. In the drawings, the first direction is represented as the X - direction, the first circumferential direction is represented as the Y - direction, and the second direction is represented as the Z - direction.

[0031] The leg rest 2 is assembled on the bracket 11. The leg rest 2 can rotate relative to the bracket 11 around the first circumferential direction to a set position and can slide along the first direction on the surface of the bracket 11 within a set area. In this embodiment, the leg rest 2 rotates around the first circumferential direction and slides along the first direction on the surface of the bracket 11 by means of a pipe fitting sleeved outside the bracket 11. At this time, the leg rest 2 can rotate around the first circumferential direction to any position and move to a set position along the first direction within the set area.

[0032] In another embodiment, the leg rest 2 rotates around the first circumferential direction and slides along the first direction through the following structure. This solution can only make the leg rest 2 slide to a set position along the first direction. A plurality of grooves are provided on the bracket 11 at intervals along the first direction. One end of the leg rest 2 is embedded in the groove and rotates around the first circumferential direction in the groove; by connecting the leg rest 2 to different grooves, the position of the leg rest 2 along the first direction is adjusted.

[0033] The locking assembly 3 connects the leg rest 2 and the bracket 11 and locks the leg rest 2 at a set position on the bracket 11.

[0034] When in use, first unlock the locking of the leg rest 2 and the bracket 11 by the locking assembly 3, rotate the leg rest 2 around the first circumferential direction, or move the leg rest 2 along the first direction, or rotate the leg rest 2 around the first circumferential direction while moving the leg rest 2 along the first direction; after moving the leg rest 2 to a suitable position to contact the patient's leg, use the locking assembly 3 to lock the leg rest 2 and the bracket 11 so that the leg rest 2 provides stable support for the patient's leg.

[0035] In this solution, by moving the leg rest 2 in the first direction, the leg rest 2 can be adapted to patients with different leg lengths for use, so that the leg rest 2 can contact the patient as needed, such as contacting the calf part of the patient, meeting the patient's usage requirements.

[0036] Since the leg rest 2 in this solution can rotate around the first circumferential direction, the surface of the leg rest 2 for supporting the leg is no longer limited to only along the first direction and is inclined at a fixed angle relative to the horizontal plane. Moreover, after further rotating a certain angle relative to the first circumferential direction, it can be inclined along the left - right direction of the seat, better adapting to the leg shapes of different patients and providing more stable support for the patient's legs.

[0037] Refer to Figure 2 , as an alternative solution, the leg rest 2 includes a connecting pipe 21 and a bracket 22. The connecting pipe 21 is sleeved on the bracket 11, the connecting pipe 21 slides along the first direction and rotates around the first circumferential direction, and the bracket 22 is fixedly connected to the connecting pipe 21 and is used to support the leg.

[0038] The locking assembly 3 connects the connecting pipe 21 and the bracket 11 and is used to lock the connecting pipe 21 at a set position on the bracket 11.

[0039] Specifically, the connecting pipe 21 is a pipe fitting sleeved on the outside of the bracket 11. The inner diameter of the connecting pipe 21 is equal to the outer diameter of the bracket 11. The connecting pipe 21 can slide relative to the bracket 11 along the first direction and rotate around the first direction. The movement of the connecting pipe 21 drives the movement of the bracket 22, and the movement of the bracket 22 realizes the adjustment of the position of the surface of the leg rest 2 for supporting the leg, so that the surface of the leg rest 2 for supporting the leg fits the patient's leg.

[0040] The locking assembly 3 locks the connecting pipe 21 and the bracket 11 to lock the leg rest 2 on the bracket 11. Only one locking assembly 3 is provided in this embodiment. In other embodiments, the number of the locking assemblies 3 can be set as required.

[0041] The connecting pipe 21 is connected to the bracket 22, and the contact surface between the connecting pipe 21 and the bracket 11 is the circumferential surface of the bracket 11, making the connection method between the leg rest 2 and the bracket 11 relatively stable.

[0042] Refer to Figure 3 , as an alternative solution, a plurality of locking holes 111 are formed on the side surface of the bracket 11.

[0043] The locking assembly 3 includes a locking pin 31 and an elastic member 32. The locking pin 31 is slidably assembled on the connecting pipe 21. One end of the locking pin 31 can slide out of the connecting pipe 21 and extend into the locking hole 111. When the connecting pin is located in the locking hole 111, the connecting pipe 21 is locked on the bracket 11.

[0044] The elastic member 32 connects the locking pin 31 and the connecting pipe 21, and is used to apply pressure to the locking pin 31 so that the locking pin 31 has the function of protruding from the connecting pipe 21 or one end of the locking pin 31 is kept within the locking hole 111.

[0045] Specifically, the locking pin 31 includes a pin rod. The locking pin 31 further includes a pull knob 312 located at one end of the pin rod. The pull knob 312 is coaxial with the pin rod. The diameter of the pull knob 312 is larger than the diameter of the pin rod. The pull knob 312 and the pin rod are fixedly connected by bolts.

[0046] Furthermore, in this embodiment, in order to facilitate the insertion of the locking pin 31 into the locking hole 111, the end of the pin rod away from the pull knob 312 is provided as a tip.

[0047] A step 311 is also sleeved and fixed on the locking pin 31. In this embodiment, a countersunk hole is provided on the side surface of the step 311, and a threaded hole is provided on the side surface of the pin rod. Bolts are used to fix the step 311 on the pin rod.

[0048] An installation pipe 33 is fixed on the side surface of the connecting pipe 21. The axis of the installation pipe 33 is along the radial direction of the connecting pipe 21. The inner diameter of the installation pipe 33 is equal to the outer diameter of the step 311. One end of the installation pipe 33 is fixedly connected to the connecting pipe 21, and the other end is provided with an inner ring. The inner diameter of the inner ring is equal to the diameter of the pin rod.

[0049] An installation hole is provided on the connecting pipe 21. The installation hole communicates the installation pipe 33 with the inner cavity of the connecting pipe 21. In this embodiment, the diameter of the installation hole is equal to the inner diameter of the installation pipe 33; in another embodiment, the diameter of the installation hole is equal to the diameter of the pin rod.

[0050] The elastic member 32 is set as a compression spring in this embodiment. The compression spring is sleeved on the pin rod. One end of the compression spring abuts against the step 311, and the other end abuts against the inner ring of the installation pipe 33.

[0051] During installation, the elastic member 32 is sleeved outside the pin rod. The step 311 is fixedly connected to the pin rod. The end of the pin rod for connecting with the pull knob 312 passes through the connecting pipe 21, so that the step 311 contacts the inner side wall of the connecting pipe 21, and the pin rod contacts the inner side wall of the inner ring. Finally, the pull knob 312 is fixed to the pin rod to realize the assembly between the pin rod and the connecting pipe 21. At this time, the elastic member 32 applies a pressure to the locking pin 31 along the radial direction of the connecting pipe 21 and towards the inner cavity of the connecting pipe 21.

[0052] When the connecting pipe 21 moves so that the locking pin 31 is aligned with the locking hole 111, the locking pin 31 is inserted into the locking hole 111 to realize the locking between the connecting pipe 21 and the bracket 11.

[0053] When it is necessary to move and adjust the position of the leg rest 2, an acting force is applied to the locking pin 31 through the pull button 312 to pull the locking pin 31 out of the locking hole 111. Then, the leg rest 2 is rotated along the first direction or around the first circumferential direction. After moving the leg rest 2 to a proper position, the acting force on the pull button 312 is removed, and the elastic member 32 pushes the locking pin 31 through the step 311 so that the locking pin 31 is inserted into the locking hole 111.

[0054] Referring to Figure 2 , as an alternative, a plurality of locking holes 111 are arranged in an array along the first direction and the first circumferential direction on the bracket 11.

[0055] Specifically, a plurality of locking holes 111 are arranged at equal intervals around the first circumferential direction, and a plurality of locking holes 111 are arranged at equal intervals along the first direction.

[0056] When the leg rest 2 moves, the locking pin 31 is connected to the corresponding locking hole 111. The locking holes 111 are arranged in an array along the first direction and the first circumferential direction, so that the patient can adjust the position of the leg rest 2 at a fixed adjustment angle or adjustment length according to needs.

[0057] Furthermore, to improve the overall structural strength of the bracket 11, a reinforcing ring is also fixed in the inner cavity of the bracket 11. The outer wall of the reinforcing ring is in close contact with the inner wall of the bracket 11. The reinforcing ring is arranged in the area of the bracket 11 where the locking holes 111 are provided, and the reinforcing ring is not shown in the drawings.

[0058] Referring to Figure 2 , as an alternative, the leg rest 2 further includes a stabilizing tube 23. The bracket 22 is fixedly connected to the stabilizing tube 23, and the stabilizing tube 23 is sleeved on the bracket 11.

[0059] Specifically, the inner diameter of the stabilizing tube 23 is equal to the outer diameter of the bracket 11. The stabilizing tube 23 is sleeved on the bracket 11. The stabilizing tube 23 and the connecting tube 21 are arranged at intervals along the first direction, and the stabilizing tube 23 is farther from the seat than the connecting tube 21.

[0060] In another embodiment, the leg rest 2 does not include the stabilizing tube 23, and only the connecting tube 21 is used to maintain the stable connection between the leg rest 2 and the bracket 11. At this time, the length of the connecting tube 21 along the first direction is longer than the length of the connecting tube 21 in the scheme of the connecting tube 21 and the stabilizing tube 23 to maintain the stable connection between the leg rest 2 and the bracket 11.

[0061] Referring to Figure 4 , as an alternative, the wheelchair further includes a chair frame 13 and an angle adjustment assembly 4. The bracket 11 is hinged to the chair frame 13 around a horizontal axis, so that the tilt angle of the bracket 11 changes when it rotates.

[0062] The angle adjustment assembly 4 connects the chair frame 13 and the bracket 11 and is used to lock the bracket 11 at a set tilt angle.

[0063] Specifically, the upper end of the bracket 11 is hinged to the chair frame 13. By rotating the bracket 11 around the hinge axis, the angle adjustment assembly 4 is used to lock the bracket 11 and the chair frame 13. In this embodiment, the adjustment assembly supports and locks the bracket 11 and the chair frame 13 through a structure similar to a telescopic rod. In another embodiment, the adjustment assembly may be a ratchet fixed to the bracket 11 and a pawl structure hinged to the chair frame 13. Through the cooperation of the ratchet and the pawl, the bracket 11 is locked to the chair frame 13.

[0064] The inclination angle of the bracket 11 changes, so that the bracket 11 can better fit the patient's leg. At the same time, the bracket 11 can be rotated to a horizontal state or an inclined state to meet the needs of different patients for the leg rest 2.

[0065] Referring to Figure 4 , as an alternative, the angle adjustment assembly 4 includes a first tube 41, a second tube 42 and a fixing member 43. The first tube 41 is hinged to the chair frame 13, and the second tube 42 is hinged to the bracket 11; the second tube 42 is slidably assembled on the first tube 41, and the fixing member 43 is used to lock the first tube 41 and the second tube 42.

[0066] Specifically, one end of the first tube 41 is hinged to the chair frame 13, and the other end is for accommodating the insertion of the second tube 42. The second tube 42 slides in the first tube 41 along the length direction of the first tube 41, and the end of the second tube 42 away from the first tube 41 is hinged to the bracket 11.

[0067] The fixing member 43 is a bolt in this embodiment. The bolt is arranged along the radial direction of the first tube 41, is arranged on the side wall of the first tube 41, is threadedly connected to the first tube 41, and one end extends into the inner cavity of the first tube 41. The end of the bolt extending into the first tube 41 contacts and presses against the second tube 42.

[0068] When the bracket 11 rotates around its hinge axis with the chair frame 13, the inclination angle of the bracket 11 changes. At this time, the second tube 42 and the first tube 41 rotate synchronously, and the second tube 42 slides relative to the first tube 41. When the bracket 11 rotates to a suitable inclination angle, the fixing member 43 is used to press and fix the first tube 41 and the second tube 42, so as to realize the adjustment of the inclination angle of the bracket 11 by the adjustment assembly.

[0069] It should be noted that in this embodiment, the hinge axes of the hinge between the bracket 11 and the chair frame 13, the hinge between the first tube 41 and the bracket 11, and the hinge between the second tube 42 and the chair frame 13 are all parallel to each other and along the left-right direction of the seat, which is represented as the second direction in the drawings.

[0070] Referring to Figure 2 , as an alternative, the leg rest 2 includes a cushion 24, and the thickness of the cushion 24 is lower at the middle along the width direction than at both ends along the width direction.

[0071] Specifically, the supporting pad 24 is an elastic pad. The length of the supporting pad 24 is set along the first direction, the width direction of the supporting pad 24 is set along the left - right direction of the seat, and the thickness of the supporting pad 24 is higher in the middle and lower at both ends along the width direction.

[0072] Furthermore, one end of the supporting pad 24 close to the seat is lower and the end far from the seat is higher along the first direction. It should be noted that the thickness change of the supporting pad 24 along both the width direction and the first direction is a gradual change, and sudden change parts should be avoided. It is precisely because the supporting pad 24 can adjust its position along the first direction and the first circumferential direction and is designed to match the shape of the leg that the stability and comfort of leg placement can be improved; when the position of the supporting pad 24 is fixed, due to the uncertainty of the leg positions of different patients, the shape adjustment of the supporting pad 24 is restricted, and it is difficult to meet the leg shape requirements of different patients.

[0073] After the patient's leg is placed on the supporting pad 24, affected by the supporting pad 24 itself, the patient's leg can be placed more stably on the leg rest 2. The structure of the supporting pad 24 increases the contact area between the leg and the supporting pad 24, further improving the stability and comfort of the patient's leg placement.

[0074] In the description of the present application, it should be noted that the orientation or positional relationship indicated by terms such as "upper", "lower", "inner", "outer", "front", "rear", "left", "right", etc. is the orientation or positional relationship based on the working state of the present application. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.
