The present invention generally relates to a strap adjustment device, and more particularly relates to a device that may be used in conjunction with a variety of differently shaped and sized straps to adjust the useful length of a strap as well as the tension provided by the strap.
Currently, bungee straps are often used, for example, to secure items such as pieces of luggage to luggage racks on vehicles. However, bungee straps of different lengths are often needed to secure pieces of luggage of different sizes and shapes, thus forcing a user to purchase many different bungee straps of different lengths.
As can be seen, there is a need for a strap adjustment device which can be used with a variety of differently shaped and sized straps, ropes, cords, belts, and/or other lengths of material, such as rubber ropes and rubber cords, for adjusting the useful length and tension of a strap used in conjunction with the device.
In one aspect of the present invention, a device comprises a housing; a first opening on a first end the housing for accepting a length of material through the housing, the first opening having a first portion and a second portion, the first portion having an arc shape, the second portion having a rectangular shape, and the first portion contiguously adjoining the second portion to form the first opening; and a locking mechanism for securing a portion of the length of material within the housing.
These and other features, aspects and advantages of the present invention will become better understood with reference to the following drawings, description and claims.
The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.
Various inventive features are described below that can each be used independently of one another or in combination with other features.
Broadly, embodiments of the present invention generally provide a device that may be used in conjunction with a variety of differently shaped and sized straps to adjust the useful length of a strap as well as the tension provided by the strap.
With reference to
The housing 13 may receive the strap 24 through the first opening 20A, and the strap 24 may leave the housing 13 through the second opening 20B. The housing 13 may be slid up and down the strap 24 and the housing 13 may be secured to the strap 24 via a locking mechanism, such as a cam lever 16, when it is at a desired location on the strap 24.
The housing 13 may be constructed from a left housing 12 and a right housing 14, which may be connected via fasteners 22, such as screws, to complete the housing 13.
With reference to
The first portion 20C and the second portion 20D of the first opening 20A may be disposed so that the second portion 20D of the opening may be situated to abut the length of the diameter side of the semi-circular shaped first portion 20C. Further, the width of the rectangular shaped second portion 20D may be wider than the diameter of the semi-circular shaped first portion 20C (and thus may extend past the edges of the semi-circular shaped first portion 20C on both sides).
In addition, the first portion 20C and the second portion 20D of the first opening 20A may be of sufficient size to receive the strap 24 having a circular cross-section with a diameter equal to the diameter of the semi-circular shape of the first portion 20C of the first opening 20A, so that the first portion 20C is able to receive a first semi-circular portion of the circular cross-section of the strap 24, and the second portion 20D is able to receive a second semi-circular portion of the circular cross-section of the strap 24.
The rectangular shaped second portion 20D of the first opening 20A may also be able to receive the strap 24 having a rectangular cross-section with the same dimensions as the rectangular shaped second portion 20D. Thus, the strap adjustment device 10 may be versatile in that it may be able to receive and secure many different straps 24 having different shapes, such as straps 24 having a circular or rectangular cross-section.
Referring now to
When the cam lever 16 is moved to the locked position, a leg 16A of the cam lever 16 may be positioned so that it may push a portion of the strap 24 within the housing 13 against an interior wall of the housing 13, thereby securing the strap 24 with the housing.
Alternatively, when the cam lever 16 is moved to the unlocked position, the cam lever 16 may be positioned so that the leg 16A no longer pushes the portion of the strap 24 within the housing against the interior wall of the housing 13. The cam lever 16 may also be connected to a hook 26 which may apply additional tension to the cam lever 16 when the cam lever is in the locked position.
It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
This application claims the benefit of priority to U.S. provisional patent application No. 61/300,105 filed Feb. 1, 2010, and incorporated herein by reference.
