Abstract

The fixing buckle includes first and second securing parts provided with coupling elements one of which defines a hook. A closure system is configured to define a first position preventing extraction of the first coupling elements from the second coupling elements and a second position allowing insertion and extraction of the first coupling elements. The closure system includes first and second closure plates each having a first position obstructing the hook and a second position configured to remove the first coupling elements. The first position of the first closure plate is configured to prevent movement of the second closure plate from its first position to its second position. The second closure plate separates the first coupling elements and the first closure plate along an extraction channel defined by the hook.

First claim

The invention claimed is:

1. A fastening buckle comprising:
a first securing part provided with a first coupling element,
a second securing part provided with a second coupling element defining a hook, the hook being configured to collaborate with the first coupling element so that the first coupling element is attached to the second coupling element in removable manner, and
a closure system defining a first position preventing extraction of the first coupling element from the second coupling element and a second position allowing extraction of the first coupling element from the second coupling element, the closure system comprising:
a first closure plate presenting a first position configured to at least partially obstruct the hook and prevent extraction of the first coupling element from the second coupling element, and a second position configured to allow extraction of the first coupling element from the second coupling element, and
a second closure plate presenting a first position preventing extraction of the first coupling element from the second coupling element by at least partially obstructing the hook, and a second position configured to allow extraction of the first coupling element from the second coupling element,

wherein
the first position of the first closure plate is configured to prevent movement of the second closure plate from the first position to the second position,
the second closure plate separates the first coupling element and the first closure plate along an extraction channel defined by the hook, and
the second closure plate is configured such that the second closure plate moves from the first position to the second position by first moving away from a free end of the hook and then second moving into a hole formed in a body of the second securing part.

2. The fastening buckle according to claim 1 , wherein, when the first closure plate is in the first position, the first closure plate at least partially masks the second closure plate so as to prevent the second closure plate from moving from the first position to the second position.

3. The fastening buckle according to claim 1 , wherein movement of the first closure plate from the first position to the second position takes place in a first direction of movement and movement of the second closure plate from the first position to the second position takes place in a second direction different from the first direction.

4. The fastening buckle according to claim 3 , wherein the first direction and the second direction define an angle at least equal to 45°.

5. The fastening buckle according to claim 4 , wherein the angle is at least equal to 90°, or at least equal to 120°.

6. The fastening buckle according to claim 1 , wherein the first closure plate and second closure plate are mounted movable in rotation and wherein rotation of the first closure plate from the first position to the second position takes place in a first direction and rotation of the second closure plate from the first position to the second position takes place in a second direction opposite to the first direction.

7. The fastening buckle according to claim 1 , wherein the first closure plate is mounted movable in translation from the first position to the second position and movable in rotation to actuate the second closure plate from the first position to the second position, the first closure plate being in the second position.

8. The fastening buckle according to claim 1 , wherein the first closure plate presses on the hook in the first position.

9. The fastening buckle according to claim 8 , wherein the first closure plate is configured to form a protective cover which masks the second closure plate to prevent actuation of the second closure plate from the first position to the second position.

10. The fastening buckle according to claim 1 , wherein the first closure plate is configured to prevent actuation of the second closure plate when the first closure plate is in the first position.

11. The fastening buckle according to claim 1 , wherein:
the first closure plate is mounted movable with respect to a support point fixed to the second closure plate,
the first closure plate comprises a blocking part, and
the first closure plate is configured so that, when the first closure plate is in the first position, the blocking part prevents movement of the second closure plate from the first position to the second position and that when the first closure plate is in the second position, the blocking part enables movement of the second closure plate from the first position to the second position.

12. The fastening buckle according to claim 11 , wherein the first closure plate is mounted rotationally with respect to the second closure plate and wherein the blocking part is mounted rotationally with respect to the second closure plate.

13. A harness comprising the fastening buckle according to claim 1 , wherein the first securing part is provided with a first attachment attached to a first strap and the second securing part is provided with a second attachment attached to a second strap.

14. A method for opening a fastening buckle comprising:
providing a first securing part provided with a first coupling element and a second securing part provided with a second coupling element defining a hook, the hook being configured to collaborate with the first coupling element so that the first coupling element is fixed to the second coupling element in removable manner, the hook being obstructed by a first closure plate and a second closure plate,
moving the first closure plate from a first position preventing extraction of the first coupling element from the second coupling element up to a second position enabling extraction of the first coupling element from the second coupling element, the first position of the first closure plate preventing movement of the second closure plate from the first position to the second position, and
moving the second closure plate from the first position preventing extraction of the first coupling element from the second coupling element up to the second position enabling insertion and extraction of the first coupling element,
wherein the second closure plate is configured such that the second closure plate moves from the first position to the second position by first moving away from a free end of the hook and then second moving into a hole formed in a body of the second securing part.

15. The fastening buckle according to claim 1 , wherein:
the second securing part is provided with a front side and a rear side opposite the front side,
the hook has the free end at the front side of the second securing part,
the rear side of the second securing part includes a flat rear surface that is configured to face a user's body, and
the second closure plate is configured such that, when the second closure plate moves from the first position to the second position, the second closure plate partially extends further rearward than the flat rear surface of the second securing part.

16. A fastening buckle comprising:
a first securing part provided with a first coupling element,
a second securing part provided with a second coupling element defining a hook, the hook being configured to collaborate with the first coupling element so that the first coupling element is attached to the second coupling element in removable manner, and
a closure system defining a first position preventing extraction of the first coupling element from the second coupling element and a second position allowing extraction of the first coupling element from
