Patent number: 8602388Abstract: The present invention discloses a manual force reduction device for reducing a force required to initiate movement of a load by a separate mechanism. The device can have an energy storage mechanism that has a compressed position and a released position, and the energy storage mechanism can be operable to store a predetermined amount of energy when it is in the compressed position. A latch can be included and be used to hold the energy storage mechanism in the compressed position. At a desired time, a latch release can release the energy storage mechanism from the compressed position such that the predetermined amount of energy is released and transferred to the load.Type: GrantFiled: October 29, 2009Date of Patent: December 10, 2013Assignee: Toyota Motor Engineering & Manufacturing North America, Inc.Inventor: Gustavo Esquivel Garcia

Patent number: 7938384Abstract: An extended length strand take up device is presented that may be used to repair damaged guy wires in the field. The invention comprises two connecting bodies connected by a single tension rod that extends continuously between the two connecting bodies. Each connecting body slides over opposite ends of the tension rod and is held in place by a stop member, such as threaded nuts screwed onto the respective ends of the tension rod. The connecting bodies may further include an inwardly-facing pull tab or tabs that can be used for pre-tensioning the guy wire. An alternative embodiment of the invention comprises a single tension rod that is fixedly anchored to the ground and several connecting bodies that are fixedly mounted along the end of the guy wire at standard increments. The tension rod runs parallel to and overlaps the end of the guy wire. The connecting bodies slide along the length of the tension rod until the required tension and length is reached.Type: GrantFiled: July 8, 2008Date of Patent: May 10, 2011Inventors: James A.
