Abstract
Abstract This invention relates to a brake control device for a brake mechanism of a cyle, comprising a control lever (7) pivotally mounted in a hollow bracket member (1) comprising a front wall (11), a rear wall (12), a pair of side walls (13), and an upper wall (15); and a clamping means (2,5) for securing said bracket member (1) to a handlebar (H) in use of the device. The control lever (7) has a support means (8) for holding one end of a control wire (W) remote from the brake mechanism and the bracket member (1) has a support means (3) for an outer stop (10) for the outer sheath (0) of the control wire (W). A mounting member (3) is mounted in said bracket member (1) and formed (34) for supporting the outer sheath stop (10) so that the control wire outer sheath (0) and the control wire (W) therein can extend naturally and be led out of the bottom of the bracket member (1), towards the handlebar (H).

Claim 2
Dependent Claim
185 words
A brake control device for a brake mechanism of a cycle, comprising a control lever (7) pivotally mounted (6) in a hollow bracket member (1) comprising a front wall (11), a rear wall (12), a pair of side walls (13,14), and an upper wall (15); and a clamping means (2,5) for securing said bracket member (1) to said handlebar (H) in use of the device; said control lever (7) having a support means (8) for holding, in use, one end of a control wire (W) remote from an other end of said control wire (W) securable to a said brake mechanism and said bracket member (1) having support means (3) for an outer stop (10) for the outer sheath (0) of a said control wire (W) characterised in that there is provided a mounting member (3) mounted in said bracket member (1) and formed (34) for supporting said outer sheath stop (10) so that said control wire outer sheath (0) and said control wire W) therein can extend' naturally and be led out of the bottom of said bracket member (1), towards said handlebar (H).
Claim 3
Dependent Claim
47 words
A device according to Claim 1, wherein said mounting member (3) has an upstanding portion (33) extending towards the upper wall (15) of said bracket member (1), said control lever (7) being pivotally mounted on a control lever pivot shaft (6) supported by said mounting member (3).
Claim 4
Dependent Claim
55 words
A device according to Claim 1 or Claim 2 wherein said mounting member (3) is in the form of a generally plate-like member which is inclined upwardly towards a first end (32) adjacent the front wall (11) of said bracket member (1) the upwardly inclined portion being formed for supporting said outer sheath stop (10).
Claim 5
Independent Claim
36 words
A device according to any one of Claims 1 to 3, wherein said control lever (7) is pivotally supported between the side walls (13,14) of said bracket member (1) on a control lever pivot shaft (6).
Claim 6
Independent Claim
113 words
A device according to any one of Claims 1 to 4 wherein said mounting member (3) is formed (31) for engagement by part of said clamping means (5) and wherein the front wall (11) of said bracket member (1) has a retaining bore (17)-and the rear wall (12) is provided with an aperture (16), said mounting member (3) being supported in said bracket member (1) by engagement with said retaining bore (17) and aperture (16), so that tightening of said clamping means (2,5) secures said mounting member (3) in position relative to said front and rear walls (11,12) whilst clamping said bracket member (1) with said mounting member (3) to the handlebar (H).
