Buckle with Tension Adjuster
In one embodiment a buckle includes at least one rectangular frame having two side members, at least one cross member parallel to and between the side members for dividing an opening formed by the frame into a plurality of slots, and two end members; and at least one strap; wherein a portion of the strap sequentially passes the slots by engaging over each of the at least one cross member is not overlapped with the end of the strap secured to one face of either side member or one face of the cross member. An easy adjustment of the tension of the strap is made possible.
1. Field of Invention
The invention relates to buckle constructions and more particularly to a buckle having at least one rectangular frame with at least one cross member wherein portions of the strap pass the slots formed between the cross member and the side member by engaging over the cross member are not overlapped such that an easy adjustment of the tension of the strap is made possible.
2. Description of Related Art
Buckles are well known devices and are used to tighten a strap around an object or to attach the ends of two straps together.
A typical type of buckle has a rectangular frame with a cross member. In detail, the buckle frame is flat and has two side members in addition to the central cross member which is somewhat flexible. A slot is formed between any two adjacent frame members so that a strap may pass through the slots by engaging over the cross member. A user may pull the strap to increase the gripping ability of the frame members on the strap, thereby securing the strap (i.e., tightening).

For the buckle of
Conventionally, the buckle strap is formed of fabric, silicone, TPU (thermoplastic polyurethane), EVA (ethylene vinyl acetate), or elastomer (e.g., rubber). However, the strap made of silicone or rubber may exert a great gripping force on any member engaged therewith. Hence, overlapped portions of the strap secured by the buckle may somewhat stick together. Hence, tensioning force adjustment of the strap by manipulating the buckle frame and the strap is made very difficult. Thus, the need for improvement still exists.
SUMMARY OF THE INVENTIONIt is therefore one object of the invention to provide a buckle comprising at least one rectangular frame having two side members, at least one cross member parallel to and between the side members for dividing an opening formed by the frame into a plurality of slots, and two end members; and at least one strap; wherein a portion of the strap sequentially passes the slots by engaging over each of the at least one cross member is not overlapped with the end of the strap secured to one face of either side member or one face of the cross member. By utilizing this buckle, an easy adjustment of the tension of the strap is made possible.
In one aspect of the invention the securing of the end of the strap to one face of either side member or the cross member is achieved by adhesive, glue, hook and loop fastener, snapping, screw fastening, or integrally forming therewith.
In another aspect of the invention the frame has two enlarged end members, an aperture in the midpoint of either end member, and an enlarged cross member above the apertures; a strap having a tube end; a shaft loosely inserted through the tube end of the strap to have both ends rotatably mounted in the apertures; and a separate bar. The strap partially wraps around the bar, sequentially passes the slots by engaging over the cross member.
The above and other objects, features and advantages of the invention will become apparent from the following detailed description taken with the accompanying drawings.
Referring to
The securing of one end 21 of the strap 20 to one face of the cross member 12 may be achieved by adhesive, glue, snapping, hook and loop fastener, screw fastening, or integrally forming therewith. Alternatively, one end 21 of the strap 20 may be secured back to any face of either side member 11 or 13.

The invention has the following advantage. Any portion of the strap in passing the rectangular buckle frame is not overlapped with itself. Hence, tension adjustment of the buckle is made easy. This is particularly suitable to a type of buckle strap (e.g., one made of silicone or rubber) which has a great gripping force on any member overlapped therewith.
While the invention herein disclosed has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
Claims
1. A buckle comprising:
- at least one rectangular frame having two side members, at least one cross member parallel to and between the side members for dividing an opening formed by the frame into a plurality of slots, and two end members; and
- at least one strap;
- wherein a portion of the strap sequentially passes the slots by engaging over each of the at least one cross member is not overlapped with the end of the strap secured to one face of either side member or one face of the cross member.
2. The buckle of claim 1, wherein one face of either side member or one face of the cross member has means for securing to one end of each of the at least one strap.
3. The buckle of claim 1, wherein the end members of the frame have a thickness greater than that of each of the cross member and the side members.
4. The buckle of claim 1, further comprising means interconnecting the end members for securing to either end of each of the at least one strap.
