Abstract

The carabiner comprises a body associated with a gate able to rotate on a first end of the body between a closed position and an open position of the carabiner. A confinement element is configured to form a first stop and a second stop salient from the body. The confinement element is fitted removable with respect to the body. The confinement element is fixed to the body by a first fastener and a second fastener. A joining part connects the first fastener to the second fastener to define the space separating the first stop and the second stop. The joining part is pressed against the body. The body, the gate and the joining part define a carabiner with a single central ring.

First claim

The invention claimed is:

1. Carabiner comprising:
a body,
a gate fitted able to rotate on a first end of the body between a closed position and an open position of the carabiner, the gate being in contact with a second end of the body when the carabiner is in the closed position,
a confinement element configured to form a first stop and a second stop salient from the body, the confinement element being fitted removable with respect to the body, the confinement element being fixed to the body by a first fastener and a second fastener,
a joining part connecting the first fastener to the second fastener to define a separating distance between the first stop and the second stop, the joining part being pressed against the body, the body, the gate and the joining part defining a carabiner with a single central ring,
wherein the first fastener and/or second fastener completely surround the body in a section plane such that the first fastener and/or second fastener form a ring around a section of the body.

2. Carabiner according to claim 1 , wherein the joining part is only in contact with an outer surface of the body between the first fastener and the second fastener.

3. Carabiner according to claim 1 , wherein the joining part is shaped to reproduce the shape of the outer surface of the body in a curved part of the body, the joining part being pressed against the curved part of the body.

4. Carabiner according to claim 3 , wherein the first fastener, the second fastener and the joining part are made from polymer material.

5. Carabiner according to claim 1 , wherein the first and/or second fasteners are provided with an anti-rotation device relatively to the body.

6. Carabiner according to claim 5 , wherein the first and/or second fasteners respectively comprise first and second recesses having a complementary shape to the shape of the body.

7. Belay system comprising a carabiner according to claim 1 and a safety device.

8. Belay system according to claim 7 , wherein the safety device is chosen from a belay device, a clamp, a lanyard or a pulley.

9. Carabiner comprising:
a body,
a gate fitted able to rotate on a first end of the body between a closed position and an open position of the carabiner, the gate being in contact with a second end of the body when the carabiner is in the closed position,
a confinement element configured to form a first stop and a second stop salient from the body, the confinement element being fitted removable with respect to the body, the confinement element being fixed to the body by a first fastener and a second fastener,
a joining part connecting the first fastener to the second fastener to define a separating distance between the first stop and the second stop, the joining part being pressed against the body, the body, the gate and the joining part defining a carabiner with a single central ring,
wherein the second fastener is fitted removable with respect to the first fastener and with respect to the joining part.

10. Carabiner according to claim 9 , wherein the first fastener is monolithic with the joining part and wherein the second fastener defines a through hole collaborating with a second through hole defined in the joining part, a connection part passing through the through hole and the second through hole to form a single-piece confinement element.

11. Belay system comprising a carabiner according to claim 9 and a safety device.

12. Belay system according to claim 11 , wherein the safety device is chosen from a belay device, a clamp, a lanyard or a pulley.

13. Carabiner comprising:
a body,
a gate fitted able to rotate on a first end of the body between a closed position and an open position of the carabiner, the gate being in contact with a second end of the body when the carabiner is in the closed position,
a confinement element configured to form a first stop and a second stop salient from the body, the confinement element being fitted removable with respect to the body, the confinement element being fixed to the body by a first fastener and a second fastener,
a joining part connecting the first fastener to the second fastener to define a separating distance between the first stop and the second stop, the joining part being pressed against the body, the body, the gate and the joining part defining a carabiner with a single central ring,
wherein the first fastener and second fastener each define a through hole collaborating with first and second connection parts chosen from screws, rivets or crimp pins to close the first and second fasteners.

14. Belay system comprising a carabiner according to claim 13 and a safety device.

15. Belay system according to claim 14 , wherein the safety device is chosen from a belay device, a clamp, a lanyard or a pulley.

16. Method for installing a safety device on a carabiner, comprising the following steps:
providing a safety device,
providing a carabiner comprising:
a body,
a gate fitted able to rotate on a first end of the body between a closed position and an open position of the carabiner, the gate being in contact with a second end of the body when the carabiner is in the closed position, and
a confinement element, the confinement element having a first fastener, a second fastener and a joining part, the first or second fastener being fixed to the body of the carabiner,

inserting the body of the carabiner in a connection hole of the safety device until a work area is reached,
fixing the other of the first or second fastener on the body of the carabiner, the first and second fastener defining first and second stops at the ends of the work area, the first and second fasteners being secured to one another by the joining part pressing on the body, the joining part defining a separating distance between the first stop and the second stop, the first stop and the second stop being salient from the body,
wherein, in a section plane, the first fastener and/or second fastener completely surround the body such that the first fastener and/or second fastener form a ring around a section of the body, and
wherein the body, the gate and the joining part defining a carabiner with a single central ring.

17. Method for installing a safety device on a carabiner, comprising the following steps:
