Benefits of technology
"The present invention provides an improved tightening device for shoes that overcomes the disadvantages of previous devices. The device includes an elongate member with means for engaging shoelace sections, a retaining means for rotatably retaining the elongate member, and a lever for tightening the shoelace sections. The device can be easily attached to a shoe and tightened with a simple lever motion. The technical effects of the invention include simplifying the tightening and loosening process of shoes and improving the fit of shoes."
Problems solved by technology
However the device of Cairns may require a high degree of dexterity to be able to grip and rotate the relatively small circular knob.
Because the device of Matias has many parts, it is likely more expensive to manufacture.
Also, the degree of weaving of the lace means that the device requires a relatively high degree of dexterity to employ.
However the device of Dickie merely holds any tension between the laces—it does not act to positively tighten the shoe as a whole.
The lever is relatively small, and thus the device of Dickie may require a high degree of dexterity.
As a result, the operation of the device in Dickie may lead to the user inadvertently touching various parts of the lace, which may be unhygienic.

Embodiment Construction
[0037]Referring to the Figures and first to FIGS. 1 and 2, there is provided a tightening device 20 having a first position as illustrated in FIG. 1 and a second position as illustrated in FIG. 2. The tightening device 20 includes a retaining means or mounting member 22, which in this case is u-shaped. Referring to FIGS. 2 and 3, the mounting member 22 has a first end 24 and a second end 26 spaced apart from the first end 24 by plate 23. A first projection 27 extends outwardly from the plate 23 at the first end 24 of the mounting member 22. The first projection 27 includes a connection member 28 located at one end 31 of the first projection 27. The connection member 28 is in the form of a hook member in this example which inwardly curves back towards the mounting member 22. The connection member 28 defines a recess 32. Another end 33 of the first projection 27 projects outwards perpendicularly from the mounting member 22. An s-shaped curve 30 extends between the inward curvature of ...

There is provided a tightening device for tightening a plurality of lace sections on a shoe. The tightening device includes an elongate member having means for engaging with the plurality of lace sections. The tightening device includes a retaining means for rotatably retaining the elongate member and for interposing between the plurality of lace sections and the shoe. The tightening device includes a lever extending from the elongate member for rotating the elongate member from a first position where the plurality of lace sections are slidably engageable with the elongate member to a second position where the lever causes the plurality of lace sections to fixedly engage around the elongate member and thereby tighten the plurality of lace sections on the shoe. The lever is connectable to the retaining means when the elongate member is in the second position.
Description
CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of provisional application 61 / 029,791 filed in the United States Patent and Trademark Office on Feb. 19, 2008, the disclosure of which is incorporated herein by reference and priority to which is claimed pursuant to 35 U.S.C. section 120.FIELD OF THE INVENTION[0002]The present invention relates to a tightening, locking & loosening device. More particularly, it relates to a tightening, locking & loosening device for simplifying the tightening and loosening of shoe laces.DESCRIPTION OF THE RELATED ART[0003]It is known to employ a device for tightening one's shoes. For example U.S. Pat. No. 2,611,940 to Cairns illustrates a circular knob with a slot that is placed between two lace sections. The knob is then rotated like a spool to wrap the lace sections therearound and thereby tighten the shoe. However the device of Cairns may require a high degree of dexterity to be able to grip and rotate the relatively s...
