Abstract

A buckle assembly ( 10 ) includes a frame ( 12 ) having a base ( 66 ) connected to opposed side walls ( 68 ). The frame ( 12 ) has a latch chamber ( 70 ) between the base ( 66 ) and the opposed side walls ( 68 ). The buckle assembly ( 10 ) also includes a lever ( 14 ) pivotally secured with in the latch chamber ( 70 ) between the opposed side walls ( 68 ), and a latch ( 16 ) configured to be secured in the latch chamber ( 70 ) by the lever ( 14 ). The latch ( 16 ) may include a frame-engaging member ( 30 ) having an ogived leading end ( 36 ). The ogived leading end ( 36 ) is configured to self-align the latch ( 16 ) within the latch chamber ( 70 ) when the latch ( 16 ) is mated into the latch chamber ( 70 ).

First claim

The invention claimed is:

1. A buckle assembly comprising:
a frame having a base connected to opposed side walls, the frame having a latch chamber between the base and the opposed side walls, wherein the frame further comprises at least one rotation-limiting member extending into the latch chamber from at least one of the opposed side walls, wherein the at least one rotation-limiting member comprises at least one semi-spherical protuberance or at least one tab;
a lever pivotally secured within the latch chamber between the opposed side walls, wherein the at least one rotation-limiting member provides a barrier past which the lever is unable to pass;
a latch configured to be secured in the latch chamber by the lever, the latch including a frame-engaging member having an ogived leading end, wherein the ogived leading end is configured to self-align the latch within the latch chamber when the latch is mated into the latch chamber; and
wherein each of the opposed side walls comprises a fastener-retaining aperture that retains a spring-biased fastener that pivotally secures the lever to the opposed side walls, and wherein each of the fastener-retaining apertures is surrounded by a fastener head-retaining ledge that receives and retains a head of the spring biased fastener in a flush manner.

2. The buckle assembly of claim 1 , wherein the ogived leading end is rounded and smooth.

3. The buckle assembly of claim 1 , wherein the frame-engaging member further comprises smooth, curved edges.

4. The buckle assembly of claim 1 , wherein the lever comprises a locking protuberance, wherein the latch further comprises a lever-retaining opening configured to receive and securely retain the locking protuberance within the lever-retaining opening, and wherein the lever-retaining opening is configured to conform to at least one dimension of the locking protuberance to prevent the locking protuberance from shifting within the lever-retaining opening.

5. The buckle assembly of claim 1 , wherein the base further comprises a debris-clearing opening configured to prevent debris from settling within the latch chamber.

6. The buckle assembly of claim 1 , wherein the base further comprises at least one waved web channel configured to retain a web or strap.

7. The buckle assembly of claim 1 , wherein the frame further comprises at least one separating member extending into or from the base.

8. The buckle assembly of claim 1 , wherein the lever comprises a securing lobe having a latch-engaging protuberance extending therefrom, wherein the latch-engaging protuberance has a latch-engaging surface area that is smaller than an entirety of the securing lobe, and wherein the latch-engaging surface area engages a portion of the latch when the latch is mated into the frame.

9. The buckle assembly of claim 8 , wherein the only portion of the securing lobe that engages the portion of the latch when the latch is mated into the frame is the latch-engaging surface.

10. The buckle assembly of claim 8 , wherein the latch-engaging surface comprises a flattened surface extending from the securing lobe through an extension beam.

11. The buckle assembly of claim 1 , wherein the lever comprises a handle having a smooth, arched opening configured to be engaged by an operator to pivot the lever between open and closed positions.

12. A buckle assembly comprising:
a frame having a base connected to opposed side walls, the frame having a latch chamber between the base and the opposed side walls;
a latch configured to be secured in the latch chamber;
a lever pivotally secured within the latch chamber between the opposed side walls, wherein the lever is configured to securely retain the latch within the frame, wherein the lever comprises a handle having a smooth, arched opening configured to be engaged by an operator to pivot the lever between open and closed positions, and a securing lobe having a latch-engaging protuberance extending therefrom, wherein the latch-engaging protuberance has a latch-engaging surface area that is smaller than an entirety of the securing lobe, and wherein the latch-engaging surface area engages a portion of the latch when the latch is mated into the frame; and
wherein each of the opposed side walls comprises a fastener-retaining aperture that retains a spring-biased fastener that pivotally secures the lever to the opposed side walls, and wherein each of the fastener-retaining apertures is surrounded by a fastener head-retaining ledge that receives and retains a head of the spring biased fastener in a flush manner.

13. The buckle assembly of claim 12 , wherein the only portion of the securing lobe that engages the portion of the latch when the latch is mated into the frame is the latch-engaging surface.

14. The buckle assembly of claim 12 , wherein the latch-engaging surface comprises a flattened surface extending from the securing lobe through an extension beam.

15. A buckle assembly comprising:
a frame having a base connected to opposed side walls, and at least one separating member extending into or from the base, the frame having a latch chamber between the base and the opposed side walls, wherein the base includes a debris-clearing opening configured to prevent debris from settling within the latch chamber, wherein the base further includes at least one waved web channel configured to retain a web or strap; and
a lever pivotally secured within the latch chamber between the opposed side walls,
wherein the frame further comprises at least one rotation-limiting member extending into the latch chamber, and wherein the at least one rotation-limiting member provides a barrier past which the lever is unable to pass,
wherein each of the opposed side walls comprises a fastener-retaining aperture that retains a spring-biased fastener that pivotally secures the lever to the opposed side walls, and wherein each of the fastener-retaining apertures is surrounded by a fastener head-retaining ledge that receives and retains a head of the spring biased fastener in a flush manner.

16. The buckle assembly of claim 15 , wherein the at least one rotation-limiting member comprises at least one semi-spherical protuberance.

17. The buckle assembly of claim 15 , wherein the at least one rotation-limiting member comprises at least one tab.
