Description

Technical Field

[0001] This utility model belongs to the field of wheelchair technology, specifically relating to a wheelchair with adjustable handles. Background Technology

[0002] Existing wheelchairs take up a lot of space when stored, which is very inconvenient for patients. For example, when traveling by public transportation or a car, the wheelchair is not easy to carry in the vehicle due to its large size, and it is also difficult to move it up and down. When not in use, it is not easy to store.

[0003] In addition, in existing wheelchairs, the handles are fixed to the wheelchair posts, and the handles cannot be adjusted relative to the posts, making them inconvenient to use and unable to flexibly adjust the angle of the handles. Utility Model Content

[0004] This invention provides a wheelchair with adjustable handles, aiming to solve the problem that the angle of wheelchair handles cannot be adjusted in the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A wheelchair with adjustable handles includes a wheelchair body, a column on the wheelchair body, and handles on the column;

[0007] The handle is mounted on the column via an angle adjustment component. The handle includes a first usage state and a second usage state. When the handle is in the first usage state, it is perpendicular to the forward direction of the wheelchair body. When the handle is in the second usage state, it is parallel to the forward direction of the wheelchair body. The handle and the column are switched between the first usage state and the second usage state via the angle adjustment component.

[0008] A further improvement: When the handle is in its first use state, the handle is oriented towards the center of the wheelchair body.

[0009] Based on the above technical solution: When the handlebars are perpendicular to the forward direction of the wheelchair, the user can easily grip the handlebars to push forward, backward, or turn. In this case, with the handlebars facing towards the center of the wheelchair, it is not only easier to operate but also prevents the handlebars from extending beyond the wheelchair body, thus avoiding obstructing the user's movement space. Furthermore, preventing the handles from extending beyond the wheelchair body also reduces the space occupied when the wheelchair is stored.

[0010] A further improvement: When the handle is in the second use state, the handle is oriented away from the wheelchair body.

[0011] Based on the above technical solution: when the handle is perpendicular to the wheelchair's forward direction, the user can easily grip the handle to push forward or turn. In this case, the handle is oriented towards the center of the wheelchair, which not only facilitates operation but also prevents the handle from extending beyond the wheelchair and affecting the user's movement space. When the handle is parallel to the wheelchair's forward direction, pushing the wheelchair is more flexible.

[0012] A further improved solution: The handle is provided with a connecting post, and the handle is rotatably connected to the angle adjustment component through the connecting post.

[0013] Based on the above technical solution, the connecting column acts as a bridge between the handle and the angle adjustment component, playing a role in transmitting force and maintaining the stability of the handle. Through the rotating connection of the connecting column, the handle can flexibly switch between different angles. Because the handle is rotatably connected to the angle adjustment component via the connecting column, the handle maintains a smooth and fluid movement when switching angles. This design not only improves the user's ease of operation but also enhances the practicality and adaptability of the wheelchair.

[0014] A further improved solution: The angle adjustment assembly includes a sleeve, the column and the connecting column are both inserted into the sleeve, the connecting column is provided with a protrusion, the sleeve is provided with an adjustment groove that cooperates with the protrusion, and a first elastic element is provided between the connecting column and the sleeve to push the connecting column so that the protrusion on the connecting column contacts the top wall of the adjustment groove. By placing the protrusion in different positions in the adjustment groove, the handle can be switched between a first use state and a second use state.

[0015] Based on the above technical solution: Because the protrusion on the connecting column fits tightly with the adjusting groove on the sleeve, coupled with the elastic force of the first elastic element, the handle maintains stable support when switching angles. This design ensures stability. Even after prolonged use and frequent operation, the angle adjustment component maintains stable performance, ensuring the overall lifespan of the wheelchair.

[0016] A further improved solution: The adjustment groove includes a first groove and a second groove, and a third groove is provided between the first groove and the second groove. Both the first groove and the second groove are connected to the third groove. When the protrusion is in the first groove, the handle is in a second use state, and when the protrusion is in the second groove, the handle is in a first use state.

[0017] Based on the above technical solution: since the adjustment groove includes a first groove, a second groove, and a third groove, and these three grooves are interconnected, the user can manually push the handle to make the protrusion move smoothly within the adjustment groove, thereby achieving flexible adjustment of the handle angle. This design improves the user's ease of operation, making the wheelchair more adaptable to different usage scenarios.

[0018] A further improved solution: the first groove and the second groove both extend upward along the axial direction of the sleeve to form the third groove.

[0019] Based on the above technical solution: the upward extension design of the first and second grooves allows for a wider adjustment range of the handle. Stable handle support is crucial for user safety during operation. The extended adjustment groove design in this invention ensures the handle remains stable during adjustment, effectively preventing safety hazards caused by handle wobbling.

[0020] A further improved solution: the first groove and the second groove both extend downward along the axial direction of the sleeve to form the third groove.

[0021] Based on the above technical solution: both the first groove and the second groove extend downwards along the axial direction of the sleeve, making the connection between the sleeve, the upright, and the connecting column more stable. This design not only improves the overall structural stability of the wheelchair but also extends its service life.

[0022] A further improved solution: The connecting post is provided with a through hole, the protrusion is slidably connected to the through hole, a second elastic element is provided inside the connecting post to push the protrusion out of the connecting post, and a limiting block is also provided on the connecting post to prevent the protrusion from sliding out of the through hole. The limiting block and the protrusion are an integral structure.

[0023] Based on the above technical solution, the user can easily adjust the handle's angle by sliding the protrusion within the through hole and by the pushing action of the second elastic element, to meet the usage needs in different scenarios. When the handle is not adjusted, the second elastic element presses the protrusion firmly against the top wall of the adjustment groove, thus ensuring the handle's stability. This design provides the user with more stable and safer support during driving.

[0024] A further improved solution: A partition is provided inside the sleeve, which divides the inner cavity of the sleeve into an upper cavity and a lower cavity. The connecting post is inserted into the upper cavity, and the upright post is inserted into the lower cavity.

[0025] Based on the above technical solution: the partition divides the inner cavity of the sleeve into two independent spaces, upper and lower, allowing the connecting post and the upright post to be inserted into the upper and lower cavities respectively. This design avoids mutual interference between the connecting post and the upright post within the sleeve, ensuring the normal functioning of each. The partition provides a clear positioning of the connecting post's depth within the upper cavity. Because the partition restricts the downward movement of the connecting post, it can only be inserted and adjusted within the upper cavity, thus ensuring the accuracy and stability of the handle adjustment. As the bottom boundary of the upper cavity, the partition effectively prevents the connecting post from being over-inserted into the sleeve. This not only avoids collisions or interference between the connecting post and the upright post or other components but also ensures the smoothness and stability of the connecting post during adjustment. Since the connecting post is restricted to insertion and adjustment within the upper cavity, users can more precisely control the insertion depth of the connecting post when adjusting the handle angle. This helps improve the precision and accuracy of handle adjustment, ensuring users receive the best user experience.

[0026] The beneficial effects of this utility model are as follows:

[0027] This invention, by incorporating an angle adjustment component, allows users to easily adjust the handle angle according to their personal preferences and needs. This design not only improves the comfort and convenience of the wheelchair but also makes it more ergonomic, meeting the individualized needs of different users.

[0028] The adjustable handles allow the wheelchair to adapt to a wider range of usage scenarios. Whether at home, in a hospital, or outdoors, users can adjust the angle of the handles to achieve the best riding experience. This design enhances the wheelchair's practicality and adaptability.

[0046] The working principle of this embodiment:

[0047] The handle 3 is in the first usage state by default, that is, perpendicular to the forward direction of the wheelchair body 1. As needed, the user can switch the handle 3 from the first usage state to the second usage state by operating the angle adjustment component. When the handle 3 is fully switched to the second usage state, the angle adjustment component will automatically lock or fix the position of the handle 3, that is, by positioning the protrusion 10 in the adjustment groove 6, the handle 3 switches between the first usage state and the second usage state, preventing it from moving accidentally during use.

[0048] The user also switches the handle 3 from the second usage state to the first usage state by operating the angle adjustment component. The switching process is the reverse of the above, and the angle adjustment component ensures that the handle 3 smoothly returns to a position perpendicular to the forward direction of the wheelchair body 1. When the handle 3 is fully switched back to the first usage state, the angle adjustment component will also automatically lock or fix the position of the handle 3.

[0049] This utility model is not limited to the above-mentioned optional embodiments. Under the premise of non-contradiction, the various solutions can be combined arbitrarily. Anyone can derive other forms of products under the guidance of this utility model.
