Quick release buckle assembly
A quick release buckle assembly has a male portion and a female portion. The male portion is inserted into the female portion to lock the buckle assembly together. The male buckle portion is connected to a cable. Pulling the cable with sufficient force causes the male portion to release from the female portion. Several buckle assemblies can be simultaneously released if the cables are connected to a single handle. Pulling on the handle then releases all of the male portions at once.
This application is a continuation-in-part of U.S. patent application Ser. No. 12/456,069, filed on Jun. 11, 2009.
BACKGROUND OF THE INVENTION1. Field of the Invention
This invention relates to a quick release buckle system. In particular, the invention relates to a quick-release buckle system that can be used on articles of clothing such as cut away vest that need to be quickly and easily removed by the wearer.
2. The Prior Art
Cut away vests are often worn by members of the military and law enforcement agencies to aid the wearer in carrying gear, as well as to protect against bullets and other impacts. These vests, especially when loaded with armor plating, can be very heavy and cumbersome to wear. Therefore it is a requirement that the vests be easily removable by the wearer, in case the wearer must be mobile in an emergency, and especially in case of submersion in water.
In the past, these vests have been constructed of several separate pieces that are held together by a cable system. An example of this system is shown in U.S. Pat. No. 7,243,376 to Johnson. A strap is threaded through each piece, with a hole in each strap. The holes are then lined up, and a cable is threaded through each hole. A loop on one of the pieces is threaded through the overlapping holes, and a cable is then fed through the loop, keeping all of the pieces joined together. In an emergency, the cable is pulled out, thus releasing all of the pieces simultaneously. This system works well to free the wearer from the vest, but it is extremely difficult to re-assemble the vest after use, so the vests are generally discarded after a single use.
SUMMARY OF THE INVENTIONIt is therefore an object of the invention to provide a quick-release buckle system that can be used on articles of clothing that need to be quickly removed, such as a cut away vest, so that the vest can be re-used for further operations. A version of this cut-away vest is described in U.S. patent application Ser. No. 12/456,069, the disclosure of which is herein incorporated by reference.
This and other objects are achieved by a quick release buckle assembly having a male portion that is inserted into a female portion. Each male buckle portion is connected to a cable. A sharp pull on the cable causes the male portion to release from the female portion to separate the buckle assembly.
In one embodiment of the buckle assembly according to the invention, each female portion comprises a hollow body with a front wall, a back wall, an open top, a cavity between the front and back walls and at least one locking slot extending through the hollow body and communicating with the cavity. Each male portion comprises a base with at least one locking leg and a central leg, such that inserting the male part into the open top of the female part causes the locking leg to engage the locking slot to lock the male portion to the female portion, as is the case with traditional side-release buckles. In a preferred embodiment, each male portion has two locking arms and each female portion has two locking slots. The male portion also can be released in the traditional manner: by pinching the locking legs together until they clear the locking slots in the female portion. However, the buckle used in the present invention has an additional feature. In this buckle, there are means for moving the locking leg toward the central leg to release the male portion—from the female portion when the cable is pulled.
The means for moving the locking leg toward the central leg can comprise a pulling assembly slidably mounted within the central leg and connected to the cable in the male portion, and arms or a strap connected one to each of the locking legs and to the pulling assembly, such that pulling on the cable causes the pulling assembly to slide away from ends of the locking legs and central leg and pull the locking legs toward the central leg. When the locking legs are pulled toward the central leg, they clear the locking slots of the female buckle portion, and the male and female portions are thus released from each other.
In one embodiment, the two locking legs can be connected by an integrally molded strap. The cable mechanism can be guided through the center leg channel and connected towards the middle of the strap. When the cable is pulled, the strap pulls down and swings the legs inwards. The strap may have different interface configurations to attach to the cable.
In another embodiment, there is a molded hollow receptacle in the middle of the strap, whereby an end piece of the cable will interface. In yet another embodiment, the cable mechanism can guide up through the center leg and split to two separate cables, each one directly connected to each leg.
The buckle assembly according to the invention has the advantage that several buckle assemblies can be connected via their cables, so that a single pull can release all of the connected buckle assemblies at the same time. For example, the cables of each of the male portions can be attached to a single handle, so that pulling the handle releases all of the buckle assemblies simultaneously. This allows a device that is being held together by several buckles to be immediately disassembled with a single motion.
Other objects and features of the present invention will become apparent from the following detailed description considered in connection with the accompanying drawings. It is to be understood however, that the drawings are designed as an illustration only and not as a definition of the limits of the invention.
In the drawings, wherein similar reference characters denote similar elements throughout the several views:
Referring now in detail to the drawings,
Male buckle portion 30 is configured so that a hard pull on cable 31 causes male buckle portion 30 to disengage from the corresponding female portion 40.
In use, pulling on cable 31 causes pulling mechanism 36 to slide back away from locking legs 34. This pulls arms 37 downward, and pulls locking legs 34 inward, as shown in
The buckle assemblies 20 are configured so that a significant amount of force, i.e., a hard tug on the cable, is needed to separate the male portion from the female portion, to prevent inadvertent disengagement of the buckle assembly during use.
Other buckle assemblies could also be envisioned within the scope of the invention. All that is required is that the male portion be releasable from the female portion by pulling on the cable.
The buckle assembly according to the invention can be used as a single buckle, or for any application where several buckles need to be released simultaneously.
Accordingly, while only a few embodiments of the present invention have been shown and described, it is obvious that many changes and modifications may be made thereunto without departing from the spirit and scope of the invention.
