Quick-release buckle for a shoulder strap and preventing unintentional release when tension is exerted by the shoulder strap
View Patent ↗A quick-release buckle for a shoulder strap and preventing unintentional release when tension exerted by the shoulder strap. The buckle includes a socket member, a plug member, and a locking member. The plug member has the shoulder strap connected thereto, and is replaceably engaged with the socket member. The locking member is an operative part of the socket member. The plug member replaceably engages in the locking member in such a manner so to be released therefrom, the locking member is released and the plug member has to be pulled in a direction opposite to that in which tension from the shoulder strap is exerted so as to prevent the unintentional release of the quick-release buckle when the tension is exerted by shoulder strap, while the tension exerted by the shoulder strap when the plug member is engaged in the locking member assures unintentional release of the quick-release buckle.
1. A quick-release buckle for a shoulder strap and preventing unintentional release when tension is exerted by the shoulder strap, comprising:
a socket member attached to a locking member, the socket member comprising a housing comprising a front wall, a rear wall, and a pair of side walls, the pair of side walls comprising a pair of grooves running externally from the front wall to a position between the rear wall and the front wall;
a plug member adapted to prevent unintentional release of the quick release buckle when the tension is exerted by the shoulder strap, the plug member replaceably engaged with the socket member and the locking member, the plug member adapted to be released from the socket member by releasing the locking member and pulling the plug member in a direction opposite the tension exerted by the shoulder strap.
2. The buckle of claim 1 ,
wherein the housing has a top; and
wherein the housing contains a chamber.
3. The buckle of claim 2 , wherein the top is open; and
wherein the top communicates with the chamber.
4. The buckle of claim 2 , wherein the front wall has a through opening; and
wherein the through opening communicates with the chamber.
5. The buckle of claim 4 , wherein the locking member comprises a plate; and
wherein the plate sits in the chamber.
6. The buckle of claim 5 , wherein the plate has a resilient locking piece; and
wherein the resilient locking piece is accessible through the through opening of the front wall.
7. The buckle of claim 6 , wherein the locking member comprises a button;
wherein the button closes the top; and
wherein the button engages the resilient locking piece to move therewith so as to allow the resilient locking piece to move down when the button is depressed.
8. The buckle of claim 6 , wherein the plug member comprises a frame;
wherein the frame is sized and shaped to intimately surround the socket member; wherein the frame has a top,
a bottom,
a front wall,
a pair of side walls, and
a rear wall.
9. The buckle of claim 8 , wherein the top of the frame is open;
wherein the bottom of the frame is open; and
wherein the bottom of the frame communicates with the top of the frame.
10. The buckle of claim 8 , wherein the front wall of the frame has a tongue extending internally therefrom towards the rear wall of the frame.
11. The buckle of claim 10 , wherein the tongue has a through opening sized and shaped to receive the resilient locking piece.
12. The buckle of claim 8 , wherein the pair of side walls of the frame have a pair of ridges running internally thereon, from the front wall of the frame to a position between the front wall of the frame and the rear wall of the frame; and
wherein the pair of ridges are sized and shaped to be slidably received in the pair of grooves.
