Abstract
A recovery device particularly useful in confined space and remote rescues. The recovery device includes a base plate, a winch coupled to the base plate, and an anchoring plate coupled to the base plate to detachably couple the base plate to an object that will support the recovery. A cord is attached to the winch to raise or lower the load to or from the recovery device or object. A guide roller assembly is coupled to the base plate to guide the cord and reduce the amount of friction on the cord that occurs when raising a load with the winch.
Claims13
A recovery device comprising:
- a base plate;
- a winch coupled to the base plate;
- an anchoring device coupled to the base plate to couple the device to a load bearing object;
- and
- a guide roller assembly having:
- a first L-shaped angle support having a side portion with a first hole having a diameter;
- a second L-shaped angle support having a side portion with a second hole having a diameter wherein the diameter of the second hole is smaller than the diameter of the first hole;
- a roller between the first and second angle supports, the roller having a substantially cylindrical shape with concave sides and a first end and a second end and an axial hole, and where the diameter of the first end of the roller is smaller than the diameter of the second end of the roller;
- and
- a roller flange having a substantially cylindrical shape and a first end and a second end and an axial hole wherein the diameter of the first end is larger than the diameter of the second end, and wherein the second end is adjacent the first end of the roller and is adapted to be detachably engaged in the first hole of the first L-shaped angle support.
7 more elements
A recovery device comprising:
- a base plate;
- means coupled to the base plate for raising or lowering a load;
- means coupled to the base plate for coupling the device to a load bearing object;
- and
- means coupled to the base plate for guiding a cord between the raising or lowering means and a load, the guide means including a first configuration to guide a cord between the raising or lowering means and an object and a second configuration to release a cord from the guide means with the guide means coupled to the base plate.
2 more elements
A guide roller assembly comprising:
- a first L-shaped angle support having a base and a side portion with a first hole having a diameter, the base of the first L-shaped angle support being configured to be coupled to a base;
- a second L-shaped angle support having a base and a side portion with a second hole having a diameter, wherein the diameter of the second hole is smaller than the diameter of the first hole, the base of the second L-shaped angle support being configured to be coupled to a base plate;
- a roller between the first and second angle supports, the roller having a substantially cylindrical shape with concave sides and a first end and a second end and an axial hole, wherein the diameter of the first end of the roller is smaller than the diameter of the second end of the roller;
- a roller flange having a substantially cylindrical shape and a first end and a second end and an axial hole, wherein the diameter of the first end is larger than the diameter of the second end, and wherein the second end is adjacent the first end of the roller and is adapted to be detachably engaged in the first hole of the first L-shaped angle support;
- and
- a securing rod detachably interposed to the hole of the roller flange and the first hole of the first L-shaped angle support and the hole of the roller and the second L-shaped angle support to secure the roller to the first and second angle supports.
3 more elements
A guide assembly comprising:
- means for guiding a cord;
- first and second means for supporting the guiding means;
- means for detaching the guiding means from only one of the first support means and the second support means and leaving the cord free of the guiding means.
