Abstract
Abstract A device for use in descending a rope 27, comprises a friction grip which can be fitted on to the rope at any point along the length of the rope without the need to thread the rope through the device. Downward load applied to the device, causes the device to lock on to the rope and prevent descent. The device has a control lever 15 which can be pulled down to reduce friction thereby bringing about a controlled descent. If the control member is released again, the device locks on to the rope and prevents further descent. <IMAGE>

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
133 words
A descending device for use in descending a
rope, the device comprising a friction device which
can be fitted on to a rope at any point along the
length of the rope without the need to thread one
end of the rope through the device, the device
being such that if the device is fitted on to an
upwardly extending rope and a downward load is
applied to the device, friction causes the device to
lock on to the rope and prevent descent, the
device having a control member which can be
urged by a user of the device in a direction to
reduce the amount of friction thereby bringing
about a controlled descent but if the control
member is released, the device locks on to the
rope again and prevents further descent.
Claim 2
Dependent Claim
133 words
A descending device for use in descending a
rope, the device comprising a friction device which
can be fitted on to a rope at any point along the
length of the rope without the need to thread one
end of the rope through the device, the device
being such that if the device is fitted on to an
upwardly extending rope and a downward load is
applied to the device, friction causes the device to
lock on to the rope and prevent descent, the
device having a control member which can be
urged by a user of the device in a direction to
reduce the amount of friction thereby bringing
about a controlled descent but if the control
member is released, the device locks on to the
rope again and prevents further descent.
Claim 3
Dependent Claim
83 words
A descending device as claimed in Claim 1,
comprising a first member, a second member and
a third member connected together to define an undulating path for the rope, the second member lying between the first and third members and being movable by the control member between a locking position in which the rope will be trapped between the second member and one of the first and third members, and a descending position in which the rope can slide along the undulating path.
Claim 4
Dependent Claim
83 words
A descending device as claimed in Claim 2, having a pair of spaced-apart side members, the first and third members each extending from one side member to the other side member, the second member having a free end so that the device can be attached to a rope at any point along the length of the rope by forming a loop in the rope, passing the loop between the side members, and hooking the loop over the free end of the second member.
Claim 5
Dependent Claim
46 words
A descending device as claimed in Claim 3, in which the free end of the second member projects beyond the side member adjacent to the free end, in such a manner as to reduce the risk of the loop of rope slipping off the second member.
Claim 6
Dependent Claim
67 words
A descending device as claimed in Claim 4, in which the second member has a mounting which lies between the side members and which engages a central part of the second member, the second member thus having two free ends and the second member being longer than the width of the gap between the side members so that each free end projects beyond the adjacent side member.
Claim 7
Dependent Claim
34 words
A descending device as claimed in any oneeof Claims 3 to 5, in which the second member is mounted directly on the control member, the control member being pivotally mounted between the side members.
Claim 8
Dependent Claim
51 words
A descending device as claimed in Claim 6, in which the control member comprises a lever mounted for pivotal movement about an axis which coincides with the first member, such that movement of the lever to and fro causes movement of the second member towards and away from the third member.
Claim 9
Dependent Claim
24 words
A descending device as claimed in any one of claims 3 to 7, in which the side members comprise a pair of side plates.
Claim 10
Dependent Claim
29 words
A descending device as claimed in Claim 8, in which the plates project beyond the third member to form a mounting point for attaching a load to the device.
Claim 11
Dependent Claim
38 words
1 0. A descending device as claimed in Claim 8 or Claim 9, in which the plates have a cut-away or recessed portion to increase the extent to which the second member can move towards the third member.
Claim 12
Dependent Claim
16 words
A descending device constructed and arranged substantially as herein described, with reference to the accompanying drawings.
Claim 13
Dependent Claim
16 words
A descending device constructed and arranged substantially as herein described, with reference to the accompanying drawings.
