Patent attributes
The present invention relates to a wheelchair improvement kit and a manual wheelchair. The improvement kit includes an anti-tip device including a pair of multifunction tube assemblies. Each multifunction tube assembly includes a mount tube configured for pivotally mounting one on each side of the wheelchair, a slide tube slidably engaged to the mount tube where both ends of the slide tube extend beyond the mount tube, a slide tube brake engaging or releasing the position of the slide tube relative to the mount tube, and an extendable pole inserted into the top of the slide tube. The top of the extendable pole is fitted with a hand grip. The anti-tip device further includes a pair of guide tubes configured for mounting one on each side of the wheelchair. When the multifunction tube assembly is used as the anti-tip device, the slide tube passes through the guide tube.
