Abstract

A load spreading belt includes a buckle closure and an elongated flexible strap having a pair of ends. A pad of locking catches is mounted on one end of the strap and a pad of catch receivers is mounted on another end of the strap. When the strap encircles a load to be retained in position, the ends of the strap overlap such that the locking catches and catch receivers are in mating engagement. The buckle includes a top and a base. A rear plate and a pair of posts spaced from the rear plate, extend between the top and the base and define a passage therebetween. One end of the strap extends through the passage with the locking catches extending outwardly on either side of each post to removably retain the buckle on the strap. In one embodiment a door is hingedly attached to the base of the buckle and closes around the strap ends when the locking catches and catch receivers are in mating engagement. In another embodiment the top and base of the buckle include recesses, and a door is frictionally engaged and retained in the recesses when positioned over the strap. The buckle provides constant clamping force in a direction transverse to the longitudinal direction of the strap thus securing the strap ends in overlapping position without a concentration of forces at a single point or line contact.

Claims

1. A belt comprising:

an elongated strap having first and second ends and front and rear surfaces;

a locking catch attached to the front surface of the strap adjacent the first end of said strap;

a catch receiver for engaging the locking catch attached to the rear surface of the strap adjacent the second end of said strap such that the ends of the strap are adapted to overlap, with said locking catch in mating engagement with said catch receiver in a latching area;

a buckle having a body and a door movably mounted on said body for movement between open and closed positions, said body having a base, a top and a rear plate, and a pair of posts extending between said base and top and spaced from said rear plate and defining a passage between said rear plate and said posts sized to accept the first end of the strap and locking catch therein for retaining the body of the buckle on said first end of the strap;

said posts and door defining a slot therebetween when the door is in the closed position for receiving the second end of the strap and catch receiver therein for mating engagement with the locking catch in the latching area between said posts.

2. A belt as defined in claim 1 in which the strap has a width and a height;

in which the distance between the base and top substantially equals the strap height;

in which the distance between the rear plate and the pair of posts equals the width of the strap; and

in which one of the locking catch and catch receiver extends outwardly from the strap and intermediate the pair of posts.

3. A belt as defined in claim 1 in which one of the locking catch and catch receiver extends outwardly from the strap on both sides of the pair of posts.

4. A belt as defined in claim 1 in which the door is pivotally attached to the base;

and in which the body includes a top which forms a releasable door catch for holding the door in the closed position.

5. A belt as defined in claim 4 in which the top of the body includes a lip;

and in which the door includes a recess for receiving the lip when the door is in the closed position.

6. A belt as defined in claim 4 in which the door includes a pair of edges;

in which a hole is formed in each edge of the door;

in which a hole is formed in the body adjacent each edge of the door; and

in which dual hinge pins extend into one hole in the door and one hole in the body for pivotally mounting the door on the body.

7. A belt as defined in claim 1 in which a recess is formed in each of the base and top of the body;

in which a lip extends along a portion of each of said recesses; and

in which the door is removably mounted in said recesses.

8. A belt as defined in claim 1 in which the door includes a pair of spaced projections sized to fit in the recesses;

and in which each projection includes a biasing member for engaging a respective lip of the recesses.

9. A belt as defined in claim 8 in which each biasing member includes a plurality of ratchet teeth for engaging a respective lip;

in which the ratchet teeth are movable between lip engaging and non-lip engaging positions; and

in which each biasing member includes a thumb support whereby pressure applied to said thumb supports will move the ratchet teeth out of engagement with the lips.

10. A belt as defined in claim 1 in which the locking catch is a pad permanently secured to the strap and having a hooked surface;

in which the catch receiver is a pad permanently secured to the strap and having a looped surface; and

in which the first and second pad are secured to each other by placing the pads in mating engagement, with the hooked and looped surfaces in contact.

11. A belt as defined in claim 1 in which the locking catch is a first plurality of ratchet teeth oriented in a first direction;

in which the catch receiver is a second plurality of ratchet teeth oriented in a second direction opposite the first direction whereby the locking catch and catch receiver may be secured to one another by placing the respective ratchet teeth in engagement.

12. A belt as defined in claim 1 further comprising safety means for preventing the door from opening should the locking catches and catch receivers inadvertently disengage.

13. The belt defined in claim 1 including pivot means for pivotally mounting the door on the body.

14. The belt as defined in claim 13 in which the pivot means is a double articulated hinge including a pair of hinge pins, each pin being pivotally attached to and extending between the base and door.

15. The belt defined in claim 1 including a pair of spaced biased members formed on the door;

in which a pair of spaced opening is formed in the body; and

in which the biased members are received within the body openings for releasably securing the door to the body.

16. The belt as defined in claim 1 in which the locking catch of the strap has a predetermined thickness;

and in which the posts are spaced from the rear plate a distance substantially equal to the thickness of the latching catch.

17. The belt as defined in claim 1 in which the base has spaced sides;

and in which the posts are spaced outwardly from said base sides.

18. The belt as defined in claim 1 in which a pair of spaced recesses are formed in the top and base of the body;

and in which the door includes a pair of spaced flexible projections slidably received in the recesses for securing the door in the closed position.
