Description

The present invention relates to buckles and more specifically to buckles which are easy to adjust and can be connected quickly.
Buckles are used for securing many different items from pants to safety belts. An early style of buckle was two D-rings attached to one end of a strap and the other end of the strap was threaded through the D-rings around the outside of the one D-ring and then back through the center of the second D-ring. The strap is then pulled tight. A similar buckle is shown in United States Patent No. 4,878,274 issued on November 7, 1989 to H. R. Patricy which shows a strap having a hook and loop type fastener thereon which is threaded through one D-ring and secured by bringing the two portions of the hook and loop type fastener together. A particular disadvantage of both types of buckles is that it can be difficult to thread one end of the strap through the D-ring.
Another securement system is shown in United States patent No. 3,057,354 issued on October 9, 1962 to D.R. Roberts et al. which shows a supporting device for a sanitary napkin including conventional sanitary napkin attaching clips and adjustable straps. The length of the straps are adjustable by the use of hook and loop type fasteners. One end of the sanitary napkin is attached to a clip by threading it through the aperture and pushing it down onto the spikes, in a fashion somewhat similar to the use of a D-ring, and then securing it in the C-shaped opening. A particular disadvantage of this attaching system is that it can be difficult to position the one end of the sanitary napkin in the clip.
Another fastening system is shown in United States patent No. 1,187,132 issued June 13, 1916 to M.C. Caulkins which shows a system for supporting stockings. The stocking is clamped between a male member and female member. A particular disadvantage of this system is that it can only be used to connect members which do not have a lot of strain put on them.
Taken alone or in combination none of these prior art references show a buckle which can be quickly connected, quickly readjusted and quickly released and which can withstand a certain amount of force. Further, none of these prior art references taken alone or together show a buckle which allows for one hand operation.
It is an object of the invention to provide a buckle device that can be quickly connected and adjusted.
In accordance with one aspect of the invention there is provided a buckle device including a male strap member which has a longitudinal axis, distal end portion and an intermediate portion. A female member of the device has an aperture formed therein dimensioned to receive the strap member, a strap engaging portion adjacent to the aperture for restraining movement of the strap member, a slot extending through an outer edge of the female member and in communication with apertures for guiding the strap member into engagement with the strap engaging portion and a protrusion extending inwardly from the outer edge of the female member for preventing the strap in the aperture from moving into the slot. The strap distal end portion releasably engages the strap intermediate portion.

Preferred embodiments of the buckle will now be described with reference to the figures wherein numerals raised by a multiple of 100 refer to like parts.
Referring to Figure 1, a buckle includes a female member shown generally at 14. Female member 14 has an aperture 24 formed therein and strap engaging portion 26 adjacent to aperture 24. A peripheral outer edge 28 of the female member 14 has a slot 30 formed therein shown in the top of female member 14 in Figure 1. Slot 30 is in communication with aperture 24. A protrusion 29 extends inwardly from peripheral outer edge 28 adjacent to slot 30. Protrusion 29 has a ball 31 at its distal end portion. Female member 14 is further provided with an attaching slot 32 at the side of the female member opposite from aperture 24. As shown here, attaching slot 32 is rectangular in shape. Extensions 33 extend outwardly from the top and bottom edge portions of female member 14 adjacent attaching slot 32.
A second embodiment of the female member of the invention is shown generally at 40 in Figure 2. Female member 40 is similar to that shown at 14 in Figure 1 except that slot 13 2 is proportionally longer than aperture 124.
A third embodiment of the female member of the invention is shown generally at 50 in Figure 4. Female member 50 is similar to that shown at 14 in Figure 1 except that it has a rounded edge portion 52 around slot 232 rather than the extensions 33 of female member 14.
A fourth embodiment of the female member of the invention is shown generally at 60 in Figure 10. Female member 60 is similar to that shown at 14 in Figure 1 except that it has a pair of slots 432 formed therein. Protrusion 429 is a straight downward extension from the outer edge 428 as compared to protrusion 29 of female member 14 which has a ball 31 at its distal end portion.
A fifth embodiment of the female member of the invention is shown generally at 70 in Figures 12 and 13. Female member 70 is similar to that shown at 14 in Figure 1 except for the following differences. Female member 70 has a pair of slots 532 formed therein. Lower portion 72 of female member 70 has an outer rib 74 extending downwardly therefrom. Outer rib 74 as shown is generally triangular in shape and has a length that increases slot end to the aperture end. An inner rib 76 is formed in female member 70 where slot 530 is in communication with aperture 524.
Referring to Figure 3, the buckle shown generally at 10 in addition to female member 14 includes a male strap member 12 and attaching strap 13. Male strap member 12 has a distal end portion 16 and an intermediate portion 18. The distal end portion 16 of the strap is adapted to be attached to the intermediate portion 18 with use of hook and loop type fasteners, commonly sold under the trade mark VELCRO. One portion 20 of the hook and loop type fastener is attached to the distal end portion 16 and the other portion 22 of the hook and loop type fastener is attached to intermediate portion 18. Hook and loop type fasteners can best be seen in Figure 11 wherein one portion 420 is attached to distal end portion 416.
An alternate embodiment of the male strap member of the invention is shown generally at 80 in Figure 14. Male strap member 80 is similar to that shown at 412 in Figure 11 except for the following differences. Distal end portion 616 has a series of apertures 82 formed therein. Intermediate portion 618 has a series of studs 84 which extend outwardly therefrom and are adapted to engage apertures 82.
Referring to Figure 3, attaching strap 13 is threaded through slot 28, folded over and attached to itself by stitching 36. A second method of attaching the female member to an attaching strap is shown in Figure 4. The attaching strap has a flexible extension 54 attached thereto. Flexible extension is threaded through slot 232 and both ends of extension 54 are attached to attaching strap 213.
A third method of attaching the female member is shown in Figure 7 wherein female member 14 is attached to a first piece of material 56. The method of attaching is similar to that shown in Figure 3 except that stitching 336 attaches the attaching strap 313 to itself and to material 56. Female member 14 is attached so at to allow pivotal movement of the female member 14 outwardly from material 56, but restrain rotational movement of the female member 14 in a direction transverse to the pivotal movement of the female member 14. Male strap member 12 is attached to second piece of material 58 by any conventional method. In such a manner, buckle 10 can be used to attach the first piece of material 56 to the second piece of material 58.
A fourth method of attaching the female member is shown in Figure 8 wherein female member 14 is attached to a first piece of material 56. Female member 14 is stitched directly onto material 56 by way of stitches 64. Male strap member 12 is attached to material 58 by any conventional method.
A fifth method of attaching female member is shown in Figure 11 wherein female member 60 is attached to attaching strap 413 by threading an end through one slot 432 and then back through the other slot 432 and then attaching strap 413 to itself by stitching 436.
The attachment of male strap member 12 to female member 14 will now be discussed with reference to Figures 9a to 9c. Male strap member 12 is inserted through slot 30 as shown in Figure 9a. It is then positioned in aperture 24 as shown in Figure 9b. The strap member 12 is then pulled tight and secured as shown in Figure 9c.
As will be appreciated by someone skilled in the art and as shown in Figures 1, 2, 4, 10 and 12, there are a number of different configurations of the female members of the invention. It will be appreciated that further modifications could be made without departing from the scope of the invention. Some of the advantages of these configurations will now be discussed.
Extensions 33 and 133 of female member 14 and 40 respectively and the pair of slots 432 and 532 of female member 60 and 70 respectively are both provided to aid in restraining 'rotational movement of female member when the female member is attached to a piece of material. The attaching methods shown in Figures 7 and 8 can be adapted to be used with any of female members 14, 40, 60 and 70 so as to allow for pivotal movement away from the material and restrain rotational movement in a direction transverse to the pivotal movement. It is important to restrain the rotational movement of the female member 14 so that one hand can be used to attach male strap member 12 to female member 14. If female member 14 can rotate then another hand would be needed to steady female member 14 while male strap member 12 is inserted therein. It will be appreciated by someone skilled in the art that the attaching method shown in Figure 4 could not be adapted to be used with one hand.
Preferably the female member is made from high strength plastic including nylon. However, it could also be made from steel, such as 1/8˝ plated roundstock, or any other suitable material. The strap member 12 is preferably made from nylon strapping but it could also be made from any other suitable materials. Steel buckles can be machine formed or cast while plastic buckles are moulded.
The size of the present buckle device can vary but typically the width will range from 1/2 to 2 inches.
It will be appreciated that the preferred buckle device described herein can be operated or used with one hand only, permitting its use by the handicapped or when the use of the other hand is required for other purposes. Also the buckle can be operated by one having diminished motor control or by a gloved hand. The preferred buckle device has a cinching feature allowing for tight and secure fastening.
Having described a preferred embodiment of the invention it will be appreciated that various modifications may be made to the structure described. For example, the female member 14 may not have a overall square shape, rather the portion having the pair of slots 32 formed therein could be larger or smaller than the portion having aperture 24 formed therein.
