Removable and replaceable walker handlebars

Abstract

This invention discloses a detachable and replaceable handlebar for a walking aid, including a handlebar bracket, a handlebar assembly, and a locking element. The handlebar bracket is mounted on the frame. The handlebar assembly is fitted onto the handlebar bracket for hand gripping. The locking element is disposed between the handlebar bracket and the handlebar assembly and is capable of locking and unlocking. When the locking element is in the locked state, it prevents the handlebar assembly from sliding out of the handlebar bracket. When the locking element is in the unlocked state, the handlebar assembly can slide out of the handlebar bracket, allowing the handlebar assembly to be replaced. The handlebar assembly of this invention is detachable and replaceable to install different handlebar assemblies for different users, improving the user experience.

Claims

1. A detachable and replaceable handlebar for a walking aid, wherein: Includes a handlebar bracket, a handlebar assembly, and a locking element; the handlebar bracket is mounted on the frame; the handlebar assembly is fitted onto the handlebar bracket for hand gripping; the locking element is disposed between the handlebar bracket and the handlebar assembly and is capable of locking and unlocking. When the locking element is in the locked state, it prevents the handlebar assembly from sliding out of the handlebar bracket. When the locking element is in the unlocked state, the handlebar assembly can slide out of the handlebar bracket so that the handlebar assembly can be replaced.

2. The detachable and replaceable handlebar of the walking aid as described in claim 1, wherein: The number of handle assemblies is multiple, and one of the multiple handle assemblies can be detachably installed on the handle bracket.

3. The detachable and replaceable handlebar of the walking aid as described in claim 2, wherein: The handle assembly is provided with a grip portion, and the outer contour shape and size of the grip portion of multiple handle assemblies are different to allow different users to grip it.

4. The detachable and replaceable handlebar of the walking aid as described in claim 1, wherein: The locking element is disposed in one of the handle bracket and the handle assembly, and engages with the other of the handle bracket and the handle assembly to prevent the handle assembly from sliding out of the handle bracket.

5. The detachable and replaceable handlebar of the walking aid as described in claim 1, wherein: The handle assembly is provided with an installation channel that extends axially. The handle bracket is provided with a shaft that slides into the installation channel. After the shaft slides into the installation channel axially, the shaft engages circumferentially with the inner wall of the installation channel, so that the handle assembly is fitted around the outer circumference of the shaft.

6. The detachable and replaceable handlebar of the walking aid as described in claim 5, wherein: The locking element is an elastic hook, which is located at the end of the shaft and can elastically extend and retract in the radial direction. The elastic hook protrudes in the sliding path of the handle assembly. After the elastic hook retracts radially, the handle assembly can slide axially to fit onto the shaft. After the handle assembly is fitted onto the shaft, the elastic hook expands radially outward to hook the side wall of the handle assembly, thereby preventing the handle assembly from sliding axially out of the handle bracket.

7. The detachable and replaceable handlebar of the walking aid as described in claim 6, wherein: The handle assembly is provided with a snap-fit ​​part located at the end of the mounting channel and having an annular structure. The elastic hook has a hook portion extending radially outward. After the handle assembly is fitted onto the shaft, the snap-fit ​​part is fitted onto the outer periphery of the elastic hook, and the hook portion hooks onto the end of the snap-fit ​​part, so that a snap-fit ​​is formed between the snap-fit ​​part and the elastic hook. The snap-fit ​​part can adjust its radial dimension to change the contact area between the end of the hook portion and the end of the snap-fit ​​part.

8. The detachable and replaceable handlebar of the walking aid as described in claim 7, wherein: The snap-fit ​​part includes a clamp and a first sidewall. The first sidewall is located at one end of the installation channel, extends axially, and can elastically expand and contract radially. The clamp is axially fitted onto the first sidewall. It also includes an adjusting bolt, which is set on the clamp and used to adjust the radial dimension of the clamp. By screwing in or out the adjusting bolt, the clamp moves the first sidewall closer to or away from the elastic hook to adjust the radial dimension of the snap-fit ​​part.

9. The detachable and replaceable handlebar of the walking aid as described in claim 1, wherein: The handle assembly includes a handle sleeve and a support sleeve. The handle sleeve is made of a flexible material, and the support sleeve is made of a rigid material. An installation channel is formed on the support sleeve, and the handle sleeve is fixedly fitted around the outer periphery of the support sleeve.

10. The detachable and replaceable handlebar of the walking aid as described in claim 1, wherein: The handlebar bracket includes a vertically extending mounting portion for fixed connection with the frame, so that the handlebar bracket is mounted on the frame of the mobility aid; the top side of the mounting portion extends in the front-rear direction to form a shaft, and the handlebar assembly is sleeved on the shaft.
