Ladder Lock for Adjustably Interconnecting Lengths of Webbing
The present disclosure relates to a buckle assembly employing a ladder lock. The ladder lock includes a pair of oppositely disposed longitudinal rungs. A set of lateral rungs are centrally positioned and serve to interconnect to longitudinal rungs. A central length of webbing is threaded through the longitudinal rungs, whereby the ladder lock can be freely adjusted along the length of the central webbing. Two lengths of side webbing are threaded through opposite sides of the lateral rungs. Anchor rungs can be included for securing each of the side webbings. In this manner, the two side webbings can be positively secured to the ladder lock, yet side to side adjustments can be achieved via the lateral rungs.

This application claims priority to co-pending application Ser. No. 61/808,356 filed on Apr. 4, 2013 and entitled “Flow Through Ladder Lock with Intersecting Double Adjustable Connecting Ladder Locks.” The contents of this co-pending application are fully incorporated herein.
FIELD OF THE INVENTIONThis disclosure relates to a buckle or ladder lock. More specifically, the disclosure relates to a ladder lock that can adjustably interconnect lengths of webbing.
BACKGROUND OF THE INVENTIONBuckle and buckle connectors are known in the art as a means for connecting straps or lengths of webbing. These connectors are used in a wide variety of fields and for a wide variety of purposes. By way of example, buckle connectors can be used to secure the belts or straps on clothing or outerwear. They can be used to secure equipment or packs for various military or recreational applications. Buckle connectors are likewise used on animal collars and leashes.
An example of a buckle construction is disclosed in U.S. Pat. No. 1,374,691 to Troop. Troop discloses a buckle made up of duplicate and opposite side members. One side includes a bar and a substantially cylindrical attaching bar. The attaching bar is connected to a strap or belt. Rivets are included for forming the belt into a closed loop about the attaching bar. The opposite side includes a transverse bar. A locker is also included. The locker takes the form of a movable cylinder. An end of the belt is threaded about the cylinder.
U.S. Pat. No. 3,591,900 to Brown discloses a belt adjuster that is provided with spaced parallel, offset but fixed bars. A third reciprocating bar is disposed between the fixed bars and cooperates with one of the fixed bars to grip a looped portion of a belt. The cooperating bars are of a noncomplimentary geometry so as to apply two lines of applied gripping pressure.
An example of a strap adjustment assembly is disclosed in U.S. Pat. No. 4,903,378 to Kasai. This assembly includes a hollow connector frame and a strap retainer that is movably mounted on the follow connector frame. The strap retainer includes a central strap engagement portion and a pair of arms that extend from the central strap engagement portion and that are non-rotatably and loosely retained in associated slots.
All of the foregoing buckles achieve their own unique and individual objective. Yet, none of these buckles provide a connector that allows connected straps to be linearly moved along the length of an additional strap. Nor do the buckles of the background art provide a “flow through” connector whereby a buckle can be adjustably positioned along the length of a strap while at the same time providing an adjustable anchor for one or more additional strap. The buckle of the present disclosure is aimed at overcoming these and other shortcomings present in the background art.
SUMMARY OF THE INVENTIONOne of the advantages of the present disclosure is achieved by providing a ladder lock with both lateral and longitudinal rungs, whereby straps can be interconnected at approximately a 90 degree angle.
Yet another advantage is accomplished by allowing a length of webbing to flow through the ladder lock between opposing edges, whereby the ladder lock can be adjustably positioned along the length of webbing.
Another advantage is attained by permitting a length of webbing to flow through a ladder lock while at the same time providing fixed anchor points for additional webbing.
Still yet another advantage is achieved by joining accessories along a first webbing with the first webbing, in turn, being attached to a second adjustable length of webbing.
The foregoing has outlined rather broadly the more pertinent and important features of the present invention in order that the detailed description of the invention that follows may be better understood so that the present contribution to the art can be more fully appreciated. Additional features of the invention will be described hereinafter which form the subject of the claims of the invention. It should be appreciated by those skilled in the art that the conception and the specific embodiment disclosed may be readily utilized as a basis for modifying or designing other structures for carrying out the same purposes of the present invention. It should also be realized by those skilled in the art that such equivalent constructions do not depart from the spirit and scope of the invention as set forth in the appended claims
For a fuller understanding of the nature and objects of the invention, reference should be had to the following detailed description taken in connection with the accompanying drawings in which:
Similar reference numerals refer to similar parts throughout the general views of the drawings.
DETAILED DESCRIPTION OF THE INVENTIONThe present disclosure relates to a buckle assembly employing a ladder lock. The ladder lock includes a pair of oppositely disposed longitudinal rungs. A set of lateral rungs are centrally positioned and serve to interconnect to longitudinal rungs. A central length of webbing is threaded through the longitudinal rungs, whereby the ladder lock can be freely adjusted along the length of the central webbing. Two lengths of side webbing are threaded through opposite sides of the lateral rungs. Anchor rungs can be included for securing each of the side webbings. In this manner, the two side webbings can be positively secured to the ladder lock, yet side to side adjustments can be achieved via the lateral rungs. The various features of the present invention, and the manner in which they interrelate, are described in greater detail hereinafter.
A length of webbing (20) can be threaded through ladder lock (10). Webbing as used herein is a broad term that is inclusive of straps, belts, or band that may be formed from a variety of materials, such as elastic, cloth, nylon etc. Webbing (20) can come in a variety of standard or non-standard widths (such as one half inch, three quarter inch, one inch, etc.). As noted in
For example,
The threading arrangement of the side webbings (20′ and 20″) in shown in
To assemble ladder lock (40) and its associated webbing or straps the webbing passes under rung (42), over (44), under (46), over (48), and under (52). This is shown by arrows aa, bb, cc, dd, and ee in
In
On the opposite side of the ladder lock another adjustable strap can be attached by passing it under (72), over (68), wrap under and back around (66) between (66) and (64), then folding back over and passing under rung (72). This is shown by arrows pp, qq, rr, and ss in
The present disclosure includes that contained in the appended claims, as well as that of the foregoing description. Although this invention has been described in its preferred form with a certain degree of particularity, it is understood that the present disclosure of the preferred form has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention.
