Embodiment Construction

[0017] refer to Figure 1A with Figure 1B , shows a belt 100 for use in a linear motion device. The belt 100 shown includes a plurality of layers 101 , 102 . The belt 100 may be constructed of a steel-based material, a polymer-based material, etc., and may be manufactured using a roll-to-roll process. Other suitable materials and processes for constructing belt 100 will be understood by those skilled in the art from the description herein.

[0018] In the illustrated embodiment, the belt 100 has an inner layer 101 and an outer layer 102 disposed on the inner layer 101 . The top portion of the outer layer 102 includes a plurality of top protrusions 106 and a plurality of top recesses 107 . The bottom portion of the outer layer 102 includes a plurality of bottom recesses 104 and a plurality of bottom protrusions 105 . The inner layer 101 includes a plurality of grooves 108 configured in the same manner as will be referred to Figure 4 to Figure 6 tooth engagement of the d...

Abstract

Provided are linear motion devices that may include a band configured to be helically interlinked into a tube, where the band includes a plurality of protrusions and a plurality of recesses that engage the plurality of protrusions to link the band with itself. The linear motion devices also include a sliding guide configured to link and unlink the band, where the sliding guide includes an outer layer, an inner layer, and a ramp between the outer and inner layers having a helical incline to support a bottom portion of the band. The linear motion devices include a driving mechanism that is in contact with the band, the driving mechanism configured to move the band through the sliding guide up the helical incline to link the band, thereby extending the tube, and to move the band through the sliding guide down the helical incline to unlink the band, thereby retracting the tube.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application No. 61 / 931,212, entitled "Linear Motion Device Positioned by Extension Tube," filed January 24, 2014, which is incorporated by reference in its entirety This article. technical field [0003] The invention relates to linear motion devices positioned by extension tubes. Background technique [0004] Linear motion devices are used in various fields and are advantageous due to their compactness in the non-extended position and strength in the extended position. These devices often use complex, expensive and heavy structures to achieve their intended use. There is a need for low cost, high strength and simple linear motion devices that can be used in fields such as robotic applications. Contents of the invention [0005] Aspects of the invention are embodied in a functional linear motion device. The linear motion device may include a band configured ...
