Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
134 words
In a disc brake operated by the movement of a rotary member rotated by a Bowden cable control bearing stop means, more particularly for cycles and especially for motor assisted cycle, the improvement that the rotary member is in the form of a drum, said stop means being independent of the drum, a portion of the control cable being wrapped around said drum through an angle at least equal to the angle of rotation imparted to the drum during braking, and anchored to the drum, releasable clamping means effecting said anchoring in such a way that the brake can be adjusted without altering said stop means, after the clamping means have been released, by rotating the drum relative to the portion of cable on the drum and re-anchorinG the cable with said clamping means.
Claim 2
Dependent Claim
134 words
In a disc brake operated by the movement of a rotary member rotated by a Bowden cable control bearing stop means, more particularly for cycles and especially for motor assisted cycle, the improvement that the rotary member is in the form of a drum, said stop means being independent of the drum, a portion of the control cable being wrapped around said drum through an angle at least equal to the angle of rotation imparted to the drum during braking, and anchored to the drum, releasable clamping means effecting said anchoring in such a way that the brake can be adjusted without altering said stop means, after the clamping means have been released, by rotating the drum relative to the portion of cable on the drum and re-anchorinG the cable with said clamping means.
Claim 3
Dependent Claim
48 words
The disc brake specified in claim 1, wherein the clamping means are in the form of a screw which engages a tapped hole in the drum and of which the head is adapted to clamp the cable portion in a groove formed in the periphery of the drum.
Claim 4
Dependent Claim
79 words
The disc brake specified in claim 1, wherein the portion of the cable wrapped around the drum is extended on each side of the drum by two bare portions, the first bare portion extending as far as a fixed stop attached to the cycle frame for the cable sheath and the second bare portion bearing a stop anchored to the cable, a return spring being situated between the latter stop and a fixed abutment attached to the cycle frame.
Claim 5
Dependent Claim
16 words
The disc brake according to claim 1, wherein said movement of the rotary member is axial.
Claim 6
Dependent Claim
97 words
The disc brake specified in claim 1, comprising two jaws which are hinged relative to one another on a pivot situated substantially in the plane of the operative portion of the disc and of which the friction surfaces may be brought closer to and further away from the disc by means of an assembly comprising a threaded rod and a nut whose axis is parallel to that of the disc, wherein the nut is formed by the drum itself which to this end, bears an internal thread adapted to co-operate with the external thread on the rod.
Claim 7
Dependent Claim
42 words
The disc brake specified in claim 5, wherein a return spring is positioned between the jaws, this spring tending to release the jaws and being anchored to those portions of the jaws projecting beyond their hinge pivot relative to the friction surfaces.
Claim 8
Dependent Claim
15 words
The disc brake according to claim 6, wherein said return spring is a tension spring.
Claim 9
Dependent Claim
59 words
The disc brake specified in claim 5, wherein the jaws are mounted on a support with a channel of U-shaped profile, the jaws being housed together in this channel in such a way that their common pivot passes through the sides of the channel, and their edges, at least locally, are supported in sliding fashion on the said sides.
Claim 10
Dependent Claim
55 words
The disc brake specified in claim 8, wherein the support has two outer wings situated in the same plane and adjoining the respective sides of the channel, and these outer wings serve to fix the support to the frame of a cycle which is to be braked or to an element attached to this frame.
Claim 11
Dependent Claim
20 words
The disc brake according to claim 8, wherein said common pivot passes through slots running parallel to the threaded rod.
