Abstract
Description
Technical Field
[0001] This application relates to the field of medical rehabilitation devices, and in particular to a mobility aid. Background Technology
[0002] Currently, walking aids are rehabilitation devices that assist walking and are suitable for rehabilitation patients who can stand independently but cannot yet walk independently. By providing stable support and balance, they help users better train their gait, reduce the risk of falls while walking, and alleviate the burden on leg muscles.
[0003] When using a walking aid, the patient manually moves the walking aid forward a certain distance, then puts it down, then moves the affected leg, and finally moves the healthy leg. Existing walking aids require frequent movement during this process, which can cause fatigue in the patient's upper limbs. Utility Model Content
[0004] This application provides a portable walking aid that facilitates the patient in lifting and moving the portable walking aid.
[0005] This application provides a portable walking aid, including a hand rest, a handle, and a limiting component, wherein the handle is hinged to the hand rest; the limiting component restricts the handle from rotating within a set range, such that the angle between the handle and the horizontal plane is between 0° and 90°.
[0006] Optionally, it also includes a support frame, which includes a crossbar, two front legs and two rear legs; wherein, the two ends of the crossbar are fixedly connected to the two front legs respectively; and two hand rests are provided, with each hand rest connected to one front leg and one rear leg respectively.
[0007] Optionally, it also includes two links, with the two ends of the links connected to the front support leg and the rear support leg on the same hand rest, respectively; the hand rest is provided with a notch, and when the handle is rotated to the horizontal position, the handle is located in the notch.
[0008] Optionally, the hand rest includes a front rest, a rear rest, and a bent component; wherein the front rest and the rear rest are spaced apart; the two ends of the bent component are fixedly connected to the front rest and the rear rest respectively, and are spaced apart from the handle; the handle is hinged to the rear rest.
[0009] Optionally, the limiting component includes a support member and a blocking member fixed on the support frame; wherein, the support member contacts the handle when the handle is rotated to the minimum angle with the horizontal plane, and is used to support the handle; the blocking member contacts the handle when the handle is rotated to the maximum angle with the horizontal plane, and is used to block the handle.
[0010] Optionally, the support member contacts the handle at the support end, which is the end of the handle away from the hinge between the handle and the hand rest.
[0011] Optionally, the limiting component restricts the handle from rotating within a set range, such that the angle between the handle and the horizontal plane is between 0°-80°, 0°-70°, 0°-60°, 0°-55°, 0°-50°, 0°-45°, 0°-40°, 0°-35°, 0°-30°, 0°-25°, 0°-20°, 0°-18°, 0°-15°, 2°-45°, 2°-40°, 2°-35°, 5°-45°, 5°-40°, 5°-35°, or 3°-45°.
[0012] Optionally, it also includes an elastic element, one end of which is connected to the handle and the other end to the hand rest, and can apply a force to the handle to increase the angle between the handle and the horizontal plane.
[0013] Optionally, the elastic element includes a torsion spring, the two arms of which respectively press against the handle and the hand rest; and / or the elastic element includes a compression spring, the two ends of which respectively press against the handle and the hand rest.
[0014] In the above technical solution, when the patient uses the portable walker of this application, the hand grips the handle tightly, and the hand only drives the handle to rotate. The portable walker itself does not rotate. When the portable walker is lifted, the front support leg and the rear support leg of the portable walker are at the same height from the ground. This process eliminates the need for the patient to rotate the portable walker, thereby reducing the burden on the patient to move the portable walker and facilitating the use of the portable walker.
[0015] When the handle is rotated to the horizontal position, there is a gap between the hand and the hand support, allowing the hand to maintain a firm grip on the handle without having to release it, which facilitates patient operation.
[0016] The elastic element allows the handle to be in a vertical position in its natural state, making it easier for the patient to grip the handle; it also reduces the upward force on the handle, making it easier to move the portable walking aid. Attached Figure Description

[0025] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present application will become clearer and more apparent.
[0026] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments. Although various aspects of embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated otherwise.
[0027] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.
[0028] This application discloses a portable walking aid. When using the walking aid, place it directly in front of the patient, hold the walking aid firmly with both hands and stand steadily. The affected leg steps out first, with the heel landing on the back leg of the walking aid. The healthy leg then steps out and is at the same level as the affected leg. After moving the walking aid forward, repeat the above actions.
[0029] When moving the walking aid forward, because its components are fixed, the hands grip the handrest, and the walking aid is rotated upwards using the rear support leg as an axis, raising the front support leg higher than the rear support leg. Simultaneously, an upward force is applied to the handrest to lift the walking aid. After moving the walking aid forward a certain distance, it is lowered, and the walking aid is rotated downwards using the rear support leg as an axis, allowing the front support leg to touch the ground. The applicant found that during the movement of the walking aid, the wrists need to exert force to rotate it, increasing the strain on the wrists.
[0030] This application discloses a portable walking aid, including a hand rest, a handle, and a limiting component. The handle is hinged to the hand rest; the limiting component restricts the handle from rotating within a set range, such that the angle between the handle and the horizontal plane is between 0° and 90°. This aid reduces the burden on patients when moving the portable walking aid and facilitates its use.
[0031] Reference Figure 1 A portable walking aid includes a hand support 1, a handle 2, and a limiting component 3. The handle 2 is hinged to the hand support 1. The limiting component 3 restricts the handle 2 from rotating within a set range, such that the angle between the handle 2 and the horizontal plane is between 0° and 90°.
[0032] For ease of explanation, we define a first direction, a second direction, and a third direction. The first direction is the front-back direction, i.e., the direction a person faces when standing on the portable walker. The second direction is the left-right direction, i.e., the left-right direction a person faces when standing on the portable walker. The third direction is the up-down direction a person faces when standing on the portable walker. In the attached diagram, the first direction is represented as the X direction, the second direction as the Y direction, and the third direction as the Z direction.
[0033] Specifically, "hand support 1" refers to the upper part of the portable walker. "Handle 2" is the part used by the patient to hold and grasp; handle 2 is hinged to the end of hand support 1 closest to the body along the first direction. (See attached image) Figure 1 The two handles 2 are in a horizontal and a vertical position, respectively.
[0034] In this embodiment, the limiting component 3 is provided with two limiting members that are fixed relative to the hand support 1. Due to the presence of the two limiting members, the handle 2 in this embodiment can rotate from the horizontal direction to the vertical direction, or from the vertical direction to the horizontal direction.
[0035] In this embodiment, the angle between handle 2 and the horizontal plane is understood as the angle between the centerline of handle 2 and the horizontal plane, where handle 2 is a rod. In another embodiment, handle 2 is an arc-shaped rod, and the angle between the line connecting the two ends of handle 2 and the horizontal plane is understood as the angle between the centerline of handle 2 and the horizontal plane.
[0036] In another embodiment, the limiting component 3 may be an angle iron fixed relative to the hand support 1. In yet another embodiment, the limiting component 3 may be part of the hand support 1, as will be described in detail below.
[0037] Furthermore, the hinge between the handle 2 and the hand support 1 is covered with a flexible plastic material, which is not shown in the attached drawings, to make the handle 2 relatively flat, so as to avoid damage to clothing or malfunction of the handle 2 caused by clothing entering during the rotation of the handle 2.
[0038] When using the portable walker described in this application, the patient grips handle 2 firmly and applies an upward force to it, causing handle 2 to rotate to a vertical position with an angle of 90° to the horizontal plane. During this process, the hand only rotates handle 2; the portable walker itself does not rotate. At this time, the forearm can be raised simultaneously, thereby raising the portable walker. The front support leg 42 and the rear support leg 43 of the portable walker are at the same height from the ground. Extending the arm forward, the portable walker moves parallel to the ground. After the affected leg moves forward and is placed on the ground, the hand applies a downward force to handle 2, rotating handle 2 to a horizontal position. At this point, the hand can press on handle 2, and the patient uses their upper limb to support their body and maintain balance.
[0039] This process eliminates the need for the patient to turn the portable walker, thus reducing the burden on the patient when moving the walker and making it easier to use.
[0040] Furthermore, refer to Figure 2 An annular groove is provided on the handle 2, which is located in the middle part of the handle 2 to guide the patient to grasp the position of the handle 2.
[0041] In another embodiment, the handle 2 is provided with an arc-shaped concave groove that matches the fingers to improve the patient's grip comfort.
[0042] Reference Figure 1 As an optional solution, the portable walker also includes a support frame 4, which includes a crossbar 41, two front support legs 42, and two rear support legs 43. The two ends of the crossbar 41 are fixedly connected to the two front support legs 42 respectively; two hand supports 1 are provided, and the two ends of any hand support 1 are connected to one front support leg 42 and one rear support leg 43 respectively.
[0043] Specifically, the two hand supports 1 are bent downwards at both ends, and the two hand supports 1 are spaced apart in the left and right direction. The upper ends of the front support 42 and the rear support 43 are fixed to the two ends of the hand supports 1 respectively to support the two hand supports 1.
[0044] The length of the crossbar 41 is set along the second direction, and both ends of the crossbar 41 are fixedly connected to two front support legs 42 respectively. The crossbar 41 and the front support legs 42 can be fixed by riveting, welding, bolt and nut assembly connection or other fixing methods.
[0045] The crossbar 41 connects and fixes the two front support legs 42 at both ends along the second direction, and the two hand supports 1 fix the front support legs 42 and the rear support legs 43, forming a fixed frame to maintain the stability of the mobility aid during use.
[0046] Furthermore, both the front support leg 42 and the rear support leg 43 are telescopic rods. Anti-slip pads are provided at the lower ends of both the front support leg 42 and the rear support leg 43.
[0047] Reference Figure 5 As an optional solution, the hand support 1 includes a front support 11, a rear support 12, and a bent component 14. The front support 11 and the rear support 12 are spaced apart; the two ends of the bent component 14 are fixedly connected to the front support 11 and the rear support 12 respectively, and are bent downwards.
[0048] Handle 2 is hinged to the rear support 12.
[0049] Specifically, the hand support 1 includes three structural parts: a front support 11, a bent component 14, and a rear support 12 arranged sequentially along the first direction. The front support 11 is fixedly connected to the front support leg 42, and the rear support 12 is fixedly connected to the rear support leg 43. The two ends of the bent component 14 are fixedly connected to the front support 11 and the rear support 12 respectively, so that the hand support 1, the front support leg 42, and the rear support leg 43 are constructed into a whole.
[0050] The front support 11 and the rear support 12 have a notch 13 along the first direction. The bent member 14 is disposed below the notch. The bent member 14 is a U-shaped member, and the opening of the U-shaped member is oriented upward in this embodiment. In another embodiment, the opening of the U-shaped member is oriented to the left or to the right.
[0051] When the hand support 1 is set as a continuous rod, the handle 2 can be rotated to a vertical position so that the hand can grip the handle 2; when the handle 2 is rotated to a horizontal position, the fingers need to be spread outward to avoid the fingers being compressed when the gap between the handle 2 and the hand support 1 decreases.
[0052] The bending element 14 allows a gap between the hand and the hand support 1 when the handle 2 is rotated to the horizontal position, so that the hand can keep gripping the handle 2 without having to release it, which is convenient for the patient to operate.
[0053] Reference Figure 2 as well as Figure 3 As an optional solution, the limiting component 3 includes a support member 31 and a blocking member 32 fixed on the support frame 4.
[0054] The support member 31 contacts the handle 2 when the handle 2 is rotated to the minimum angle with the horizontal plane, and is used to support the handle 2; the blocking member 32 contacts the handle 2 when the handle 2 is rotated to the maximum angle with the horizontal plane, and is used to block the handle 2.
[0055] Specifically, the upper surface of the support member 31 contacts the lower surface of the handle 2 in a horizontal state. In this embodiment, the support member 31 is set as a rigid block fixed on the front support 11.
[0056] In another embodiment, the support 31 is fixed to the rear support 12, and the support 31 is a U-shaped block with the opening facing upward.
[0057] The blocking member 32 is fixed to the rear support 12. In this embodiment, the blocking member 32 is configured as a rigid block fixed to the rear support 12. The surface of the blocking member 32 facing the front support 11 in the first direction contacts the surface of the vertical handle 2 facing the rear support 12 in the first direction. Figure 2 To facilitate display, a gap was added between the handle 2 and the rear support 12.
[0058] Reference Figure 2 as well as Figure 3 As an alternative, the support member 31 contacts the handle 2 at the support end, which is the end of the handle 2 away from the hinged end of the handle 2 and the hand support 1.
[0059] Specifically, one end of the support member 31 is fixed to the front support 11, and the other end extends into the gap between the front support 11 and the rear support 12.
[0060] When handle 2 is rotated to the horizontal position, the patient will press handle 2 with their hand to support their body. At this time, handle 2 bears a large pressure. Support 31 contacts the support end, and the torque on support 31 is relatively small. Support 31 can provide stable support for handle 2.
[0061] Reference Figure 1 As an alternative, when handle 2 is rotated to the horizontal position, it does not mean that handle 2 is absolutely horizontal. Depending on the design requirements, handle 2 can have a small angle with the horizontal plane. Handle 2 can be rotated to a vertical position or to a tilted position. The tilted handle 2 can also make it easier for the patient to apply force to the mobility aid.
[0062] Specifically, in this embodiment, the handle 2 can be rotated to a horizontal or vertical position. In another embodiment, the minimum angle between the handle 2 and the horizontal plane is any angle between 0° and 5°, excluding 0° and including 5°. The maximum angle between the handle 2 and the horizontal plane is any angle between 15° and 90°, excluding 90° and including 15°.
[0063] The limiting component 3 restricts the handle 2 from rotating within a set range, such that the angle between the handle 2 and the horizontal plane is between 0°-80°, 0°-70°, 0°-60°, 0°-55°, 0°-50°, 0°-45°, 0°-40°, 0°-35°, 0°-30°, 0°-25°, 0°-20°, 0°-18°, 0°-15°, 2°-45°, 2°-40°, 2°-35°, 5°-45°, 5°-40°, 5°-35°, or 3°-45°.
[0064] Reference Figure 4As an alternative, the mobility aid also includes an elastic element 6, one end of which is connected to the handle 2 and the other end to the hand support 1, and can apply a force to the handle 2 to increase the angle between the handle 2 and the horizontal plane.
[0065] Specifically, when the handle 2 is rotated from the vertical position to the horizontal position, the deformation of the elastic element 6 gradually increases, and the elastic force applied by the elastic element 6 to the handle 2 becomes greater; when it is necessary to rotate the handle 2 from the horizontal position to the vertical position, the pressure of the palm on the handle 2 is removed, and the elastic element 6 pushes the handle 2 to rotate until the handle 2 is rotated to the vertical position.
[0066] The elastic element 6 allows the handle 2 to be in a vertical position in its natural state, making it easier for the patient to grasp the handle 2; it also reduces the upward force on the handle 2, making it easier to move the portable walking aid.
[0067] Reference Figure 4 As an optional solution, the elastic element 6 includes a torsion spring 61, the two arms of which respectively press against the handle 2 and the hand support 1.
[0068] The elastic element 6 includes a compression spring 62, the two ends of which respectively press against the handle 2 and the hand support 1.
[0069] Specifically, the torsion spring 61 is sleeved on the hinge shaft between the handle 2 and the hand support 1. One of the lever arms of the torsion spring 61 is fixed relative to the hand support 1, and the other lever arm is fixed relative to the handle 2.
[0070] A connecting block 121 is fixed on the rear support 12. The connecting block 121 is L-shaped with its opening facing upward and towards the front support 11. One end of the compression spring 62 is fixed on the connecting block 121, and the other end presses against the hand support 1.
[0071] In another embodiment, the elastic element 6 includes only a torsion spring 61. In another embodiment, the elastic element 6 includes only a compression spring 62.
[0072] Reference Figure 1 As an optional solution, the portable walker also includes two links 5, with the two ends of the links 5 connected to the front support leg 42 and the rear support leg 43 on the same hand support 1, respectively.
[0073] The handle 1 has a notch 13. When the handle 2 is rotated to a horizontal position, the handle 2 is located inside the notch 13.
[0074] Specifically, one end of each of the two connecting rods 5 is fixedly connected to one of the two front support legs 42 along the first direction, and the other end is fixedly connected to one of the two rear support legs 43. Notch 13 is attached. Figure 6 The image is illustrated using a dashed box.
[0075] Reference Figure 5 When the hand support 1 includes the front support 11, the rear support 12 and the bending member 14, the connecting rod 5 can increase the stability of the connection between the front support leg 42 and the rear support leg 43.
[0076] Reference Figure 1 When the hand support 1 includes the front support 11 and the rear support 12, and there is no bending part 14 connecting the front support 11 and the rear support 12, the connecting rod 5 can connect and fix the front support leg 42 and the rear support leg 43.
[0077] Reference Figure 6 as well as Figure 7 As an optional solution, the handle 2 is an L-shaped part with the opening facing the front support 11. The handle 2 includes a first rod 21 and a second rod 22, which are fixedly connected. The first rod 21 and the second rod 22 have the same thickness. The thickness of the first rod 21 is the thickness along the third direction when the first rod 21 is placed horizontally, and the thickness of the second rod 22 is the thickness along the first direction when the first rod 21 is placed horizontally.
[0078] The upper end face of the rear support 12 along the third direction is above the first rod 21 in the horizontal state; the lower end face of the rear support 12 along the third direction is below the first rod 21 in the horizontal state.
[0079] The first rod 21 is used for the patient to hold and grasp, and the first rod 21 and the second rod 22 are used to limit the handle 2. The connection between the first rod 21 and the second rod 22 is hinged to the hand support 1, and the outer side of the connection between the first rod 21 and the second rod 22 is provided with rounded corners.
[0080] When the first rod 21 rotates to the vertical position, its side wall contacts the side wall of the notch 13, and the side wall of the notch 13 prevents the first rod 21 from rotating upward. When the first rod 21 rotates to the horizontal position, its side wall contacts the side wall of the notch 13, and the side wall of the notch 13 prevents the first rod 21 from rotating downward, thus limiting the movement of the handle 2.
