摘要： A crutch has an adjustable crosspiece between two upright tube portions thereof, which includes a main body having tunnels lengthways extending along two end portions, two engaging pins respectively in the tunnels, springs for making the pins project out from the tunnels, two control members positioned next to and movable along the end portions of the main body, and two linearly displaceable bars on lateral sides of the main body, each of which connects a respective one of the pins to a respective one of the control members such that the pins are displaceable together with the control members; immediately after the control members are moved further away from each other, the pins will be retreated into the tunnels and disengaged from the uprights, and the crosspiece is adjustable; after the crosspiece is moved to a new position, the control members are released for the pins to engage the upright tubes.

摘要： A brake assembly has a wheel body, a first stopping device, and a second stopping device. The wheel body has a central axle and two engaging portions formed respectively on two ends of the central axle. The first stopping device is connected with the engaging portions of the wheel body and has a resilient member and a magnetic unit. The resilient member is C-shaped and has a lateral rod and an inclined rod connected integrally with an end of the lateral rod. The magnetic unit is mounted on the lateral rod of the resilient member and has a sleeve having a bottom opening and a magnetic element mounted in the sleeve and selectively abutting the wheel body. The second stopping device is connected securely with the lateral rod of the resilient member and is engaged selectively with the engaging portions of the wheel body.
