Abstract
A wheelchair brake system comprises: a brake which is provided in a wheel of a wheelchair; and a brake actuation controller which connects with the brake and locks and releases the brake, wherein the brake is usually in a lock mode, but the brake actuation controller controls the brake to be switched over from the lock mode to a release mode if sensing that a user sits down on the wheelchair or the wheelchair is folded up.
Claims19
A wheelchair brake system comprising:
- a brake which is provided in a wheel of a wheelchair;
- and
- a brake actuation controller which connects with the brake and locks and releases the brake,
- wherein the brake is usually in a lock mode, but the brake actuation controller controls the brake to be switched over from the lock mode to a release mode when sensing that a load is applied to the wheelchair or the wheelchair is folded up;
- wherein the brake actuation controller comprises:
- a connection member which has a first end elastically connecting with the brake;
- a brake switching member to which a second end of the connection member is fixed, and which actuates the connection member connecting with the brake to release the brake when the load is applied to the wheelchair, but returns the connection member to switch the brake over to the lock mode when the load is removed from the wheelchair,
- wherein the connection member comprises a cable or a bar;
- the brake switching member is non-motorized or motorized for automatic actuation, and
- wherein the non-motorized brake switching member comprises:
- a sensing frame which is provided beneath a seat of the wheelchair, and accommodates a second end of the cable therein to be fixed and connected thereto;
- and
- an upper plate which couples with the sensing frame and changes tension of the cable by pressing the cable accommodated in the sensing frame when the load is applied to the seat.
