Abstract

A securing device has a main body having a first side wall, a second side wall, and at least one first slot for receiving a strap, and a top bar connected to the main buckle body at the first side wall and forming a second slot with the main buckle body for receiving a second strap. The second slot is open at a distal end thereof. The top bar has a guide track extending longitudinally therethrough, with the guide track opening into the second slot. A catch is formed on the second side wall and facing inward. A spring gate is disposed in the guide track. The spring gate is placed around the catch to close the distal end of the second slot. The spring gate is releasable from the catch by pressing on the top bar until the spring gate clears the catch.

First claim

What is claimed is:

1. A securing device comprising:
a main body having a first side wall and a second side wall,
a top section connected to the main body at the first side wall, and wherein a gap is formed between a distal end of the top section and the second side wall, wherein the top section has a guide track extending longitudinally therethrough, the guide track having an opening to a space outside the top section;
a hook formed on the second side wall facing the first side wall,
a spring gate in the shape of a loop with overlapping end portions, the spring gate being configured to be assembled with the main body by inserting the spring gate in the guide track and sliding the spring gate to the distal end of the guide track,
wherein the spring gate is configured to press into the hook in a resting position to close the gap between the second side wall and the top section, and wherein the gap is opened by pressing the spring gate inward to release the spring gate from the hook.

2. The securing device according to claim 1 , wherein the top section further comprises a slot for receiving a strap, wherein the slot has an opening to a space between the side walls.

3. The securing device according to claim 2 , wherein the guide track connects to the slot at an oblique angle to a longitudinal extension of the guide track.

4. The securing device according to claim 2 , further comprising a strap extending through the slot and around the top section, wherein tension on the strap away from the main body presses the strap against the top section and compresses the guide track.

5. The securing device according to claim 1 , wherein there is at least one protrusion extending into the guide track at the distal end of the guide track to keep the spring gate at the distal end of the guide track.

6. The securing device according to claim 5 , further comprising a reinforcing protrusion extending into the guide track at an opposite end of the guide track from said at least one protrusion.

7. The securing device according to claim 1 , wherein the end portions of the spring gate have extensions that extend perpendicular to a circumferential direction of the spring gate and in opposite directions to each other.

8. The securing device according to claim 7 , wherein the top section contains grooves in communication with the guide track, the grooves being configured to receive the extensions of the spring gate when the spring gate is positioned at the distal end of the guide track, such that force on the top section away from the main body presses the extensions deeper into the grooves to prevent the spring gate from opening.

9. The securing device according to claim 1 , wherein the spring gate is formed from metal wire.

10. The securing device according to claim 1 , further comprising a strap retainer pivotably connect to the top section, the strap retainer having a central slot for receiving a strap.

11. The securing device according to claim 1 , wherein the guide track has a curved shape.

12. The securing device according to claim 11 , wherein the guide track is formed by a top bar extending toward the first side wall and a support bar extending from the first side wall toward the gap and parallel to the top bar, and wherein a space between the top bar and the support bar opens into the guide track.
