Abstract
Abstract A device for actuating a sheathed control cable comprises a push button wh is movable to apply a tension to the cable. An inclined surface rigid with the push button engages, via a ball, a traction member anchored to the cable. When the button is depressed the inclined surface displaces the traction member via the ball whereby the cable is tensioned. The ball rolls along the inclined surface during this movement whereby such movement occurs substantially without friction.

Total Claims: 9
Claim 1
Independent Claim
72 words
A device for actuating a sheathed control cable, said device comprising a casing, push button means actuable to exert a tension on the cable, said push button means being slidable in the casing, means defining an inclined surface rigid with the push button means, a traction member slidably mounted in the casing, the cable being fixed to the traction member, and ball means interposed between the inclined surface and the traction member.
Claim 2
Independent Claim
72 words
A device for actuating a sheathed control cable, said device comprising a casing, push button means actuable to exert a tension on the cable, said push button means being slidable in the casing, means defining an inclined surface rigid with the push button means, a traction member slidably mounted in the casing, the cable being fixed to the traction member, and ball means interposed between the inclined surface and the traction member.
Claim 3
Dependent Claim
46 words
A device according to claim 1, further comprising a control element having an end portion, said casing having means defining a guide opening, said end portion of the control element extending through the guide opening, and said inclined surface being a part of the control element.
Claim 4
Dependent Claim
34 words
A device according to claim 2, wherein the control element comprises a shoulder, and the casing comprises an inner abutment surface, the shoulder contacting said abutment surface in the inoperative state of the device.
Claim 5
Dependent Claim
45 words
A device according to claim 1, further comprising a control element having a shoulder, said inclined surface being a part of the control element and the casing having an inner abutment surface, the shoulder contacting said abutment surface in the inoperative state of the device.
Claim 6
Dependent Claim
26 words
A device according to claim 1, wherein the push button means is movable in a direction perpendicular to the direction of displacement of the traction member.
Claim 7
Dependent Claim
27 words
A device according to claim 1, wherein the traction member comprises a cavity through which said inclined surface extends and in which the ball means is engaged.
Claim 8
Dependent Claim
35 words
A device according to claim 6, wherein said cavity has a part-cylindrical edge in contact with the ball means, and the radius of said part-cylindrical edge is equal to the radius of the ball means.
Claim 9
Dependent Claim
