Mr Doublebina (Doublebiner) - rope friction lowering device:

My invention is a compact lightweight metal lowering device for use with fibre rope to be used safely by Arborists, Climbers, Riggers, Rescuers & Military, or anyone working with ropes.

Mr Doublebina includes the rope safely within locking gates where friction is gradually amplified by placing the rope through the device correctly until it gradually becomes a knot.

Once the 'load' is applied, the friction is gradually released in a controlled manner... allowing the rope to proceed slowly through the device (or stopped & locked)... allowing the 'load' to be lowered by the operator with absolute control. The 'load' safely includes 1 or multiple people with equipment in Rescue/Military applications.

The safe 'load' is defined by the WLL of the rope, application, and specific size/shape(variable) tested WLL of the device. Mr Doublebina can be used with any fibre rope within the WLL parameters of the rope, but is primarily designed for use with modern aramid fibre ropes.

Mr Doublebina complements other heavy-load friction lowering devices like the 'Portawrap', but entirely exceeds the traditional 'Rescue-8' and many other belay devices for climbers/rescuers because of its dynamic rope-friction amplification providing better safety, more applications, and its simple compact 2-dimensional attachment & presentation.

My 'Intellectual Property' I'm seeking to protect within this WIPO Patent is not the exact shape or size of the Mr Doublebina example - but the way rope can be safely captured within locked gates through the simple 2-dimensional frame amplifying dynamic releasable friction, allowing safe lowering of varying loads including people.
