FIELD OF THE INVENTION
-
This invention generally relates to a utility strap, and more particularly, to a hanger for articles which includes a pliant strap with a releasable, size-adjustable, self-tightening loop portion of the strap configured to clutch and hold an article on the strap, and a hanger.
BACKGROUND
-
Adjustable straps are well known in the art. Such straps typically utilize one or more manually adjustable loops, buckling devices, ring elements, snap fit arrangements and/or hook and loop type fasteners. While such straps are generally suitable for their intended purpose, they have drawbacks relating specifically to adjustability and/or ease of use. In particular, many of these designs frequently are difficult to adjust, requiring substantial dexterity and patience to achieve a desired size. Additionally, the prior art designs typically lack the range of adjustability to securely clutch and hold a wide range of articles. Consequently, such prior art adjustable straps are not be suitable for all users or for clutching a wide range of articles.
-
Thus, a need exists for an adjustable, self-tightening utility strap that is suitable for hanging and versatile and quick and easy to use. Such an adjustable strap should be adjustable to securely clutch and hold a variety of articles.
-
The invention is directed to overcoming one or more of the problems and solving one or more of the needs as set forth above.

DETAILED DESCRIPTION
-
The invention relates to a utility strap comprised of a pliant strap with a releasable, self-tightening loop portion of the strap configured to clutch and hold an article on the strap, and a hanger. Referring to FIG. 1, an exemplary utility strap with a releasable, self-tightening loop portion and a hanger according to principles of the invention is conceptually illustrated. The exemplary utility strap comprises an elongate strap 145 of pliant material that, for reference purposes, may be conceptually divided into an upper end zone 155 and a lower end zone 160. By way of example and not limitation, the strap 145 may be comprised of polypropylene, nylon or polyester webbing or other material suitable for a support strap. The material is preferably durable, weather resistant, relatively inexpensive and suitable for use in conventional manufacturing operations. To prevent fraying, the edges of the strap 145 may be melted, folded over and sewn into place, and/or covered with a sewn binding tape.
-
The upper end zone of the exemplary utility strap includes a hanging device 110 for suspending the utility strap from a hook 100 or the like mounted on a wall 105 or other structure. The hanging device 110 may be comprised of a ring, such as the D-ring shown in FIG. 1, an O-ring or a ring have another shape. A D-ring 110 is preferred because it is self-centering on a hook and includes a straight section for engagement by the strap 145. The straight section avoids stress concentrations and bunching. As an alternative, a snap hook, snap ring, swivel hook, pole strap hook, carabiner, grommets or other device adapted for engaging a hook and suitable for use with the strap 145 may be used.
-
To secure the hanging device 110 to the strap 145, the upper end 125 of the strap 145 is passed through the D-ring 110 and folded over and stitched 120 onto the strap 145. Other means of securement, such as melting, chemical bonding, rivets 115 and or grommets, could be used in lieu of or in addition to stitching.
-
The lower end zone of the exemplary utility strap includes a connector, e.g., half of a two-piece buckle assembly 140. A mating connector, e.g., the other half of the two-piece buckle 135 is slidingly disposed on the strap 145 between the hanging device 110 and the lower end half of the two-piece buckle assembly 140. In a preferred implementation, the buckle assembly is a center release or side release snap buckle that is sized appropriate to the strap.
-
As shown in FIG. 1, the lower end half of the two-piece buckle assembly 140 is secured to the lower end 150 of the strap 145. To secure the lower end half of the two-piece buckle assembly 140 to the strap 145, the lower end 150 of the strap 145 is passed through a slot in the buckle piece 140, and then folded over and stitched onto the strap 145. Other means of securement, such as melting, chemical bonding, rivets and or grommets, could be used in lieu of or in addition to stitching.
-
In use, an object is inserted in a loop formed by joining lower buckle piece 140 to upper buckle piece 135. The loop is comprised of the adjoined buckle pieces 135 and 140, and the interposed portion of the strap 145. The utility strap is suspended from a hook 100 by the hanging device 110. The lower buckle piece 140 remains stationary, while the upper buckle piece 135 slides along the length of the strap 145 under the weight of the suspended object, causing the loop to tighten around the object in a noose-like fashion—the heavier the object, the greater the downward force. Thus, the clutching force exerted on the object is proportional to the weight of the object.
-
Referring now to FIG. 2, an exemplary utility strap with a releasable, adjustable, self-tightening loop portion and a hanger according to principles of the invention is conceptually illustrated. The exemplary utility strap comprises an elongate strap 230 of pliant material that, for reference purposes, may be conceptually divided into an upper end zone 255 and a lower end zone 260. By way of example and not limitation, the strap 230 may be comprised of polypropylene, nylon or polyester webbing or other material suitable for a support strap. The material is preferably durable, weather resistant, relatively inexpensive and suitable for use in conventional manufacturing operations. To prevent fraying, the edges of the strap 230 may be melted, folded over and sewn into place, and/or covered with a sewn binding tape.
-
The upper end zone of the exemplary utility strap includes a hanging device 210 for suspending the utility strap from a hook 200 or the like mounted on a wall 205 or other structure. The hanging device 210 may be comprised of a ring, such as the D-ring shown in FIG. 2, an O-ring or a ring have another shape. A D-ring 210 is preferred because it is self-centering on a hook and includes a straight section for engagement by the strap 230. The straight section avoids stress concentrations and bunching. As an alternative, a snap hook, snap ring, swivel hook, pole strap hook, carabiner, grommets or other device adapted for engaging a hook and suitable for use with the strap 230 may be used.
-
To secure the hanging device 210 to the strap 230, the upper end 220 of the strap 230 is passed through the D-ring 210 and folded over and stitched onto the strap 230. Other means of securement, such as melting, chemical bonding, rivets 215 and or grommets, could be used in lieu of or in addition to stitching.
-
The lower end zone of the exemplary utility strap includes a connector, e.g., half of a two-piece buckle assembly 240. A mating connector, e.g., the other half of the two-piece buckle 225 is slidingly disposed on the strap 230 between the hanging device 210 and the lower end half of the two-piece buckle assembly 240. In a preferred implementation, the buckle assembly is a center release or side release snap buckle that is sized appropriate to the strap.
-
As shown in FIG. 2, the lower end half of the two-piece buckle assembly 240 is adjustably attached to the strap 230. To secure the lower end half of the two-piece buckle assembly 240 to the strap 230, the lower end 245 of the strap 230 is weaved through slots in the buckle piece 240. This configuration allows cinch-type adjustment of the lower buckle piece 240 by sliding motion of the buckle piece 240 along the length of the strap 230. Other means of adjustable securement, such as cam locks could be used in lieu of weaving through slots. Advantageously, the lower piece of the buckle 240 can be readily moved when the strap 230 is loose, but will maintain its adjusted length when supporting weight.
-
Optionally, the lower end zone of the exemplary utility strap may include a lower hanging device 250 for suspending an object from the utility strap. The lower hanging device 250 may be comprised of a ring, such as the rectangular ring 250 shown in FIG. 2, a D-ring or a ring having another shape. To secure the lower hanging device 250 to the strap 230, the lower end 245 of the strap 230 is passed through the rectangular ring 250 and folded over and stitched onto the strap 230. Other means of securement, such as melting, chemical bonding, rivets and or grommets, could be used in lieu of or in addition to stitching.
-
In use, an object is inserted in a loop formed by joining lower buckle piece 240 to upper buckle piece 225. The loop is comprised of the adjoined buckle pieces 225 and 240, and the interposed portion of the strap 230. The utility strap is suspended from a hook 200 by the hanging device 210. The lower buckle piece 240 remains stationary, while the upper buckle piece 225 slides along the length of the strap 230 under the weight of the suspended object, causing the loop to tighten around the object in a noose-like fashion—the heavier the object, the greater the downward force. Thus, the clutching force exerted on the object is proportional to the weight of the object. The position of the lower buckle piece 225 may be adjusted to accommodate suspended objects having various sizes and/or to maintain a suspended object a determined distance from the hanging device 210.
-
Concomitantly, the lower hanging device 250 may be utilized to suspend one or more additional objects or to engage the same hook 200 as the hanging device 210. In the latter mode of use, the lower hanging device 250 carries some load, thereby relieving the stress exerted on the buckle pieces 225 and 240. This mode of use is particularly useful for securing a heavy object for an extended period of time.
-
The buckles may be comprised of any material suitable for carrying the intended loads, such as polyvinyl chloride (PVC), polyethylene, polypropylene, polystyrene, acrylics, cellulosics, acrylonitrile-butadiene-styrene terpolymers, urethanes, nylons, thermo-plastic resins, thermo-plastic elastomers (TPE), acetal resins, polyamides, polycarbonates and polyesters, as well as metals, alloys and composites. By way of example and not limitation, plastics such as acetal resins, nylon, and polypropylene are suitable for use in quick-snap buckles according to principles of the invention. Acetal resins such as such as Dupont's Delrin® and/or Hoechst Celanese Celcon® provide relatively high stiffness and tensile strength and resists moisture absorption. Consequently, acetal resins perform very well under humid, freezing and arid conditions. Nylon offers excellent impact resistance under normal operating temperatures, is light, flame retardant and provides a softer feel than acetal for side release buckles. Depending upon the manufacturing process, nylon may provide a 20-30% increase in tensile strength over acetal. However, nylon absorbs water and under freezing conditions can become embrittled. Polypropylene is relatively inexpensive and suitable for use where load bearing and impact strength are not key considerations. While many other materials may be used alone or in combination with the aforementioned materials and/or other materials, without departing from the scope of the present invention, preferably the material is relatively inexpensive and durable, easy to use in manufacturing operations and results in an aesthetically acceptable product. The material may further include additives to provide desired properties such as desired colors, structural characteristics, glow-in-the-dark (phosphorescent) properties and thermal reactivity (e.g., color changes according to heat).
-
The buckles may be may be produced using any suitable manufacturing techniques known in the art for the chosen material, such as (for example) injection, compression, structural foam, blow, or transfer molding; polyurethane foam processing techniques; vacuum forming; and casting. Preferably, the manufacturing technique is suitable for mass production at relatively low cost per unit, and results in an aesthetically acceptable product with a consistent acceptable quality.
-
While the invention has been described in terms of various embodiments, implementations and examples, those skilled in the art will recognize that the invention can be practiced with modification within the spirit and scope of the appended claims including equivalents thereof. The foregoing is not intended to limit the invention to the exact construction and operation shown and described. Alternative embodiments of the invention, including variations in size, materials, components, shape, form, function, manner of operation, assembly and use that are obvious to one skilled in the art are intended to be encompassed by the invention. Accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
