Abstract
Portable power driven rope climbing apparatus having a motor driving a gear reduction mechanism which drives a pulley wheel securing a rope extending thereabouts. A rope output guide member is provided for maintaining the rope in engagement with the pulley wheel an attachment mechanism for attaching an external load. The attachment mechanism comprises a rope entry guide member for supporting a rope as it enters the apparatus, so as to provide a fulcrum point about which the mass of the apparatus exerts a first moment. The attachment mechanism further comprises a seat member for supporting the load. The seat member is held remote from the main body such that the load, when mounted thereon exerts a second, opposed moment about the fulcrum.
Claims31
A portable power driven rope climbing apparatus comprising:
- a main support body;
- a power driven rotational input means mounted on said body;
- a drive shaft mounted on said body having a main pulley wheel co-axially mounted thereon;
- a gear reduction mechanism for transmitting a rotational force between said input means and said drive shaft;
- said main pulley wheel comprising engaging means for securely engaging a rope extending thereabouts such that rotation of said pulley wheel effects displacement of said rope;
- a rope input guide member and a rope output guide member for maintaining said rope in engagement with said pulley wheel about the majority of the pulley wheel circumference;
- and an attachment mechanism mounted on said main support body for releasably securing an external load thereto, and a rope entry guide member which supports said rope as it enters the apparatus and provides a fulcrum point about which the mass of the apparatus exerts a first moment, and wherein said attachment mechanism further comprises a seat member for suspending the load therefrom, said seat member being held remote from said main support body such that said load, when mounted thereon, exerts a second, opposed moment about said fulcrum, thereby causing pivotal displacement of the apparatus away from the load.
An apparatus as claimed in 3, wherein said power driven rotational input means has a first rotational axis and said drive shaft has a second rotational axis extending parallel to and remote from said first rotational axis, with said gear reduction mechanism extending transversely between said first and second axis.
A portable power driven rope climbing apparatus comprising:
- a main support body;
- a power driven rotational input means mounted on said body;
- a drive shaft mounted on said body having a main pulley wheel co-axially mounted thereon;
- a gear reduction mechanism for transmitting a rotational force between said input means and said drive shaft;
- said gear reduction mechanism comprises a spur gear mechanism;
- said main pulley wheel comprising engaging means for securely engaging a rope extending thereabouts such that rotation of said pulley wheel effects displacement of said rope;
- a rope input guide member and a rope output guide member for maintaining said rope in engagement with said pulley wheel about the majority of the pulley wheel circumference;
- an attachment mechanism mounted on said main support body for releasably mounting an external load thereon, and a rope entry guide member supporting said rope as it enters the apparatus and providing a fulcrum point about which the mass of the apparatus exerts a first moment, and wherein said attachment mechanism further comprises a seat member for suspending said load therefrom, said seat member being held remote from said main body such that said load, when mounted thereon, exerts a second, opposed moment about said fulcrum.
A portable power driven rope climbing apparatus comprising:
- a main support body;
- a power driven rotational input means mounted on said body;
- a drive shaft mounted on said body having a main pulley wheel co-axially mounted thereon;
- a gear reduction mechanism for transmitting a rotational force between said input means and said drive shaft;
- said main pulley wheel comprising engaging means for securely engaging a rope extending thereabouts such that rotation of said pulley wheel effects displacement of said rope;
- a rope input guide member and a rope output guide member for maintaining said rope in engagement with said pulley wheel about the majority of the pulley wheel circumference;
- and an attachment mechanism mounted on said main support body for releasably securing an external load thereto, and a rope entry guide member supporting said rope as it enters the apparatus and providing a fulcrum point about which the mass of the apparatus exerts a first moment, and wherein said attachment mechanism further comprises a seat member for suspending said load therefrom, said seat member being held remote from said main body such that said load, when mounted thereon, exerts a second, opposed moment about said fulcrum, at least one of said input guide member and said rope output guide member comprises a rotatable pulley wheel rotatable in a first direction and restrained from displacement in a second opposed direction.
