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 an attaching structure, e.g., a buckle, 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.
In order to appropriately don and removably attach such strap-based attachable arrangements, various attaching structures are used. For example, these attaching structures are located at specific positions on the various straps, and often allow the user to don the attachable arrangement, engage the attaching structures to secure the attachable arrangement on the user's body, and thereafter, adjust the straps (again, through one or more of the attaching structures) in order to obtain a comfortable fit. Such attaching structures include, but are not limited to, a clip, a buckle, a mating arrangement, an actuatable structure, and the like.
Many attaching structures are in the form of a frame with some mechanism operatively engaged therewith for use in manipulating one or more of the straps of the attachable arrangement. In particular, one strap is attached to a first end of the frame, and the same or another strap is adjustably and moveably engaged with the mechanism, e.g., a friction mechanism, a mechanical arrangement, or the like. In order to adjust the moveable strap, the user must grasp the frame and move it to some position, and simultaneously pull the engaged strap to tighten or loosen it. Accordingly, the frame becomes an integral part of the manipulation and strap adjustment process.
One common drawback associated with many of these existing attaching structures (as discussed above) stems from the manipulation of the frame to effectively tighten or loosen the strap engaged with the mechanism. In particular, such prior art frames are small and difficult to grasp and move, thereby leading to difficulty in adjustment. Further, and based upon the size and form of the frame of the attaching structure, when attempting to adjust the engaged strap, the user's hand often slips off of the frame. Still further, in the type of environments where such attachable arrangements are utilized, it is common that the user will be wearing gloves on his or her hands. Attempting to manipulate the frame of the attaching structure using a gloved hand proves additionally difficult, and leads to greater slippage and the inability to effectively adjust the strap.
Accordingly, there remains a need in the art of attachable arrangements, such as belts, harnesses, safety equipment, and the like, for an improved attaching structure. In particular, there remains a need for an improved attaching structure for use in connection with adjusting the straps of such an attachable arrangement. There is a further need for an attaching structure, e.g., a buckle, that provides additional gripping and manipulation characteristics for use in adjusting the straps of an attachable arrangement. There is a still further need in the art for an attaching structure that permits quick and effective manipulation and adjustment of the straps of the attachable arrangement in the field, while the user is dressed in safety equipment, e.g., gloves.
Generally, the present invention provides an attaching structure that overcomes some or all of the drawbacks and deficiencies existing in the prior art. Preferably, the present invention provides an attaching structure that leads to increased effectiveness in adjusting a strap associated with an attachable arrangement. Preferably, the present invention provides an attaching structure that provides enhanced gripping and manipulation characteristics for use in adjusting the straps of an attachable arrangement.

While specifically discussed in connection with a full body harness having multiple straps 102, the attaching structure 10 of the present invention is useful in connection with any strap-based attachable arrangement 100 that has straps 102 that require some adjustment after donning the attachable arrangement 100. Still further, the attachable arrangement 100 may use multiple attaching structures 10 according to the present invention located at various positions on or over the attachable arrangement 100 (e.g.,
Still further, the presently-invented attaching structure 10 may be in the form of a clip, a buckle, an attaching structure, a mating arrangement, and the like. In a preferred embodiment, the present invention is directed to an attaching structure 10 in the form of a buckle having an adjustment mechanism associated therewith. In another preferred and non-limiting embodiment, this buckle is a friction buckle, i.e., the adjustment mechanism includes one or more components that permit frictional adjustment of the straps 102 of the attachable arrangement 100 that are associated with the attaching structure 10.
According to the prior art, and with reference to
While there are different types of adjustment mechanisms 116 that can be used in connection with such attaching structures 104, one common adjustment mechanism 116 is a friction mechanism 118. This friction mechanism 118 includes an adjustor bar 120 extending across the opening 114 and movably engaged with the frame 106. In particular, the adjustor bar 120 slides back and forth laterally on the frame 106. This adjustor bar 120 includes a contact surface 122 for contacting a surface of a strap 102. In operation, the strap 102 slides over the contact surface 122 of the adjustor bar 120.
Still further, the adjustment mechanism 116 includes a contact member 124 extending across the opening 114. This contact member 124, like the adjustor bar 120, is movably engaged with the frame 106, and slides back and forth laterally on the frame 106, preferably away from and towards the adjustor bar 120. Further, the contact member 124 includes a contact surface 126 for contacting an opposing surface of the strap 102.
With reference to
As discussed above, the present invention relates to an improved attaching structure 10 for use in connection with the straps 102 of an attachable arrangement 100. One preferred and non-limiting embodiment of the attaching structure 10 is illustrated in

Further, in this embodiment, the contact member 34 extends across the opening 28 and is also laterally movable with respect to the frame 12, preferably moveable towards and away from the adjustor bar 32. The contact member 34 also includes a contact surface 38 for contacting a second surface 136 of the strap 132. It is the interaction between the movable adjustor bar 32 and moveable contact member 34 that permits the strap 132 to move relative to the frame 12, and be adjusted when the frame 12 of the attaching structure 10 is oriented in an appropriate direction (as indicated by arrow A). When the frame 12 is released or untouched, the strap 132 is frictionally gripped and firmly held between the adjustor bar 32 and contact member 34. In this manner, the strap 132 can be adjusted by the user after donning the attachable arrangement 100, and when released, hold the strap 132 in place in order to achieve the intended purpose of the attachable arrangement 100, i.e., providing safety in specific environments and under certain conditions.
