Extended grabber pole1/10/2024 ![]() ![]() ![]() The reach of the tool is fixed by the length of the operator linkage to the grasping apparatus, making interchangeable or extendable poles impractical.Such prior tools have some or all of the following disadvantages: A limited number of tasks can be performed by the apparatus. It has a fixed reach length due to the operating mechanism. ![]() This conventional form of reacher-grabber tool has limitations for the user with weak finger muscles or no gripping capability. The appendages open and close by squeezing a spring handle style trigger or pulling a rope at the opposite end of the pole. Prior reacher-grabber tools provide clamping appendages with gripping ends that extend from an end of a pole. 6,467,823 issued to Brekken on October 2002. 5,823,590 issued to Forrest on October 1998, and U.S. 4,613,179 issued to van Zelm on September 1986 U.S. 8,091,936 issued to Graziano on January 2011 U.S. Various types of reacher-grabber tools are known in the prior art. The invention relates to multi-purpose reacher-grabber tools offering functionality to reach and manipulate hard-to-reach objects. used reach extenders to demonstrate that the human brain quickly learns to map tools as parts of the body.This application claims the priority benefit of pending provisional patent application 61/527,665, filed on Aug. ![]() Ī 2009 neuroplasticity study by Cardinali et al. Reach extenders are also used to provide accessibility to people with disabilities or who are aging. People may construct specially adapted tools for this purpose. Reach extenders are used by litter collection services to aid in picking up litter off the ground without having to bend over repeatedly, which is very fatiguing. Variations on the basic form of a reach extender depend on what task needs to be accomplished, and significant variation is found in the length of the pole and the maximum weight the reach extender can bear. Some designs allow rotation of the plane in which the jaws operate relative to the trigger grip, allowing less-awkward manipulation of different objects. Other designs have jaws equipped with suction cups for holding round objects more easily, and still others have small magnets for collecting lightweight ferrous items. Gripping force can range up to 17 pounds (7.7 kg) in some models. Some reach extenders may possess a secondary trigger which locks the jaws in position around whatever object they are holding, so the user does not need to maintain a tight grip on the handle. The jaws are open by default and spring open when the trigger is released. The handle is equipped with a trigger that, when pulled, closes the jaws via a lever-and-spring system or mechanical cable within the pole. The tool is available in lengths ranging from 24 inches (610 mm) for wheelchair users, up to at least 16 feet (4.9 m). The tool is commonly sold in hardware stores.Ī reach extender takes the form of a long metal or plastic pole, usually around 3 feet (0.91 m) in length, with a handle at one end and a pair of jaws at the other end.

It has applications in waste management, assistive technology, gardening and outdoor work, and in some cases as a children's toy.
