1. Field of the Invention
The present invention relates generally to attachable arrangements, e.g., harnesses, belts, fall protection arrangements, and the like, and in particular to a strap management apparatus and arrangement for use in connection with such attachable arrangements.
2. Description of the Related Art
As is known in the art, there exist various embodiments and arrangements that are attachable to a person to provide assistance to the wearer or ensure the wearer's safety in certain situations. Such attachable arrangements come in many forms, including, but not limited to, harnesses, safety belts, climbing harnesses, fall protection harnesses, safety harnesses, and fall protection arrangements. While there are many variations in such attachable arrangements, all normally include one or more elongate straps that are adjustable to fit different wearers. In operation, a person will don the attachable arrangement, attach the straps around the specified parts of his or her body, and adjust these straps to fit comfortably, yet effectively.
For example, full body harnesses are widely used for lifting and lowering individuals in dangerous situations and as a primary component in a personal fall arrest system. These harnesses can also be used for work positioning, travel restriction, ladder climbing, rescue retrieval, and evacuation. While these harnesses are used mainly in an industrial setting, and particularly the construction industry where the likelihood and danger of falls from heights is both numerous and significant, a full body harness can be used in various other applications in which total suspension and support of the body must be ensured, either expectedly or unexpectedly. Various harnesses are illustrated in U.S. Pat. Nos. 6,804,830; 5,957,091; and 4,712,513, all of which are incorporated herein by reference.
One common drawback associated with many of these existing strap-based attachable arrangements is the existence of the loose or free ends of the straps after adjustment thereof. These free ends potentially pose a safety risk in situations that require the use of an attachable arrangement. In a fall protection environment, loose or free ends may get caught or tangled, which could result in a variety of unsafe and dangerous conditions. Therefore, there is a need to hold or attach these free strap ends to keep them from dangling loosely from the attachable arrangement.
According to the prior art, in many instances, the wearer will tuck the free ends of the straps into his or her pockets, or alternatively wrap or knot these ends around the tightened straps on the remaining portions of the attachable arrangement. However, tucking or tying these straps is not ideal, as more often than not, these straps will become loose again while the wearer is engaged in various activities.
In an attempt to address these situations, manufacturers have arrived at various strap attachment arrangements and devices. For example, on harnesses that include side D-rings, a slot may be provided on the sides for tucking the free ends of the leg straps. However, these D-rings are not adjustable, nor are they flexible, such that dislodgement remains an issue. Further, many attachable arrangements do not include these D-rings. As another example, a hook can be attached to the end of the strap, and this hook is engaged with a side of a tightened strap. However, this hook may easily be disengaged in use, which results in excess strap material dangling in and around the user's body.
As another example, certain attachable arrangements include flexible bands or loops attached around one or more of the straps, and the user must manipulate the band or loop and insert the free end of the strap. However, manipulating the band or loop is quite difficult in the field, especially given that the user is usually wearing work gloves. In order to permit easier manipulation, some manufacturers provide a tab attached to the band or loop. However, in practice this tab still proves difficult for the user to grasp and manipulate the band or loop. Further, when using such a tab, and in operation, the resultant opening through which the free end of the strap can be inserted is triangular or some other shape that makes it difficult to quickly and effectively insert the free end of the strap, often leading to the wearer “giving up” and using one of the above ineffective, but easily implemented, methods.
Accordingly, there remains a need in the art of attachment arrangements, such as belts, harnesses, safety equipment, and the like for an improved strap management system and arrangement. In particular, there remains a need for a strap management apparatus and arrangement that is equally useful in connection with new and existing attachable arrangements, where the strap management apparatus is easy to adjust and manipulate for insertion of the free end of a strap. Such ease of manipulation (particularly in the field and during use) decreases any likelihood of catching the loose end of a strap on objects in the environment, which may result in a dangerous situation.
Generally, the present invention provides a strap management apparatus and arrangement that overcomes some or all of the drawbacks and deficiencies existing in the prior art and provides a strap management apparatus and arrangement that is useful in connection with new and existing attachable arrangements, e.g., harnesses, belts, and the like. Preferably, the present invention provides a strap management apparatus and arrangement that can be adjusted by the user along the length of a strap of an attachable arrangement. Preferably, the present invention provides a strap management apparatus and arrangement that is easy to manipulate in the field and during use of the attachable arrangement. Preferably, the present invention provides a strap management apparatus and arrangement that, in operation, allows for the easy insertion of the free end of a strap of an attachable arrangement.
In a preferred and non-limiting embodiment, the present invention provides a strap management apparatus for an attachable arrangement including at least one elongate strap having at least one free end. The strap management apparatus includes a substantially rigid member having a body with a first end and a second end, and at least one substantially elastic member operatively engaging the body of the rigid member and a portion of at least one strap of the attachable arrangement. The rigid member is configured to be urged away from the portion of the at least one strap, thereby creating an opening through which the at least one free end of at least one strap can be inserted.
In another preferred and non-limiting embodiment, the present invention provides an attachable arrangement, including at least one elongate strap having at least one free end, and at least one strap management apparatus. The strap management apparatus includes: (i) a substantially rigid member having a body with a first end and a second end; and (ii) at least one substantially elastic member operatively engaging the body of the rigid member and a portion of at least one strap of the attachable arrangement. The rigid member is configured to be urged away from the portion of at least one strap, thereby creating an opening through which at least one free end of at least one strap can be inserted.
In a still further preferred and non-limiting embodiment, the present invention provides an attachable arrangement for removable attachment to a person. The attachable arrangement includes a plurality of elongate attachment straps, and at least one of the plurality of attachment straps includes at least one free end. Further, the attachable arrangement includes at least one strap management apparatus, including: (i) a substantially rigid member having a body with a first end and a second end; and (ii) at least one substantially elastic member operatively engaging the body of the rigid member and a portion of at least one of the plurality of straps of the attachable arrangement. The rigid member is configured to be urged away from the portion of at least one of the plurality of straps, thereby creating an opening through which the at least one free end of at least one of the plurality of straps can be inserted.

The present invention is directed to a strap management apparatus 10 for use in connection with an attachable arrangement 100, which includes at least one, and typically many, elongate straps 102 that include at least one free end 104. Various preferred and non-limiting embodiments of this strap management apparatus 10 are illustrated in
In addition, the presently-invented strap management apparatus 10 can be configured for use in connection with existing attachable arrangements 100, i.e., as a retrofit component or device, or installed and used during the manufacturing of the attachable arrangement 100, i.e., prior to sale or use by a distributor or consumer. While specifically discussed in connection with a full body harness having multiple straps 102, the strap management apparatus 10 of the present invention is useful in connection with any strap-based attachable arrangement 100 that has straps 102 with free ends 104 that dangle or otherwise remain loose when the attachable arrangement 100 is positioned on the user. Still further, the attachable arrangement 100 may use multiple strap management apparatuses 10 at various positions on or over the attachable arrangement 100 (e.g.,
As illustrated in schematic form in
In another preferred and non-limiting embodiment, the width of the body 14 of the rigid member 12 is substantially the same as or greater than the width of the strap 102 of the attachable arrangement 100. Similarly, the width of the opening 22 through which the free end 104 of the strap 102 can be inserted may be substantially the same as (e.g., the embodiment of

Further, this tip 30 may be coated, roughened, textured, contoured, shaped, and/or flexible. In addition, and like the tab 24, the tip 30 may be manufactured from rubber, a synthetic material, a flexible material, a coated material, a roughened material, a textured material, and/or a contoured material. As seen in the embodiment of
As illustrated in the preferred and non-limiting embodiments of
In another preferred and non-limiting embodiment, the body 14 of the rigid member 12 includes a groove 44 that extends at least partially across an upper surface 46 of the body 14. The elastic member 20 (or elastic band 42) extends along the groove 44, which acts as a seat for the band 42. See
In yet another preferred and non-limiting embodiment, and as illustrated in
It is envisioned that the strap management apparatus 10 can be permanently attached to specific areas or positions along the straps 102, i.e., those positions that are in optimal areas for receiving and attaching the free ends 104 of some of the straps 102. However, in a preferred and non-limiting embodiment, the strap management apparatus 10 is adjustably slidable along the length of the strap 102. In particular, by using an elastic band 42 that extends around the strap 102 (but is not attached thereto), the strap management apparatus 10 can be moved along the strap 102 by urging the body 14 away from the strap 102 sufficiently to allow for this sliding adjustment.
As discussed above, the presently-invented strap management apparatus 10 may be used in connection with an existing attachable arrangement 100, or installed during the manufacturing and assembly process. For example, in one preferred and non-limiting embodiment, and as illustrated in
As seen in the embodiment of
In this manner, the present invention provides a strap management apparatus 10 that is useful in connection with new and existing attachable arrangements 100. Further, the present invention provides a strap management apparatus 10 and arrangement 100 that can be adjustable, easy to manipulate in the field, and holds the free ends 104 of the straps 102 in a safe position with respect to the user.
Although the invention has been described in detail for the purpose of illustration based on what is currently considered to be the most practical and preferred embodiments, it is to be understood that such detail is solely for that purpose and that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover modifications and equivalent arrangements that are within the spirit and scope of the appended claims. For example, it is to be understood that the present invention contemplates that, to the extent possible, one or more features of any embodiment can be combined with one or more features of any other embodiment.
