Abstract
A wire activated brake system for a walking aid is provided, comprising wheels wherein the system comprises a pull system to activate the brakes, the pull system comprises, a housing and a brake lever and a brake wire wherein the brake wire exits the housing on the same side as the brake levers protrudes the housing. Furthermore, a brake actuator is provided, wherein the brake actuator comprises a deflection member, a wedge, a support member comprising a sliding surface, wherein the wedge is pretensioned in a position between the deflection member and the support member.
Claims17
A wire activated brake system for a walking aid comprising wheels, the wire activated brake system comprising a pull system to activate the brakes, the pull system comprising:
- a housing, and:
- a brake lever connected to a brake rail latch, wherein the brake rail latch is situated at least partly inside the housing and wherein the brake rail latch is hinged around at least one pivot member connected to the housing, and;
- a brake wire connected to the brake rail latch at an anchor point between the at least one pivot member and the brake lever, such that a manipulation of the brake lever rotates the brake rail latch around the at least one pivot member thereby causing a manipulation on the brake wire,
- wherein the brake wire exits the housing on the same side as the brake levers protrudes the housing.
A wire activated brake system for a rollator comprising a brake actuator, the brake actuator comprising
- a deflection member comprising a friction member, and;
- a wedge having a two opposite faced sliding surfaces, wherein the opposite faced sliding surfaces have an inclination towards each other to form a wedge shape, thereby comprising a wider section and a thinner section, and;
- a support member comprising a sliding surface, wherein the wedge is situated between the deflection member and the support member, and the first sliding surface of the wedge is adapted to slide against a back part of the deflection member and wherein second sliding surface of the wedge is adapted to slide against the sliding surface of the support member,
- wherein the wedge is pretensioned in a position between the deflection member and the support member, and wherein the wedge is connected to a brake wire adapted to displace the wedge in a direction away from the pretensioned state of the wedge, whereupon the wider section forces a free end of the deflection member comprising the friction member in a direction towards a braking surface when the wedge is forcibly displaced by force from the brake wire.
