Quick-release attachment point for fall protection
View Patent ↗A quick-release attachment point for fall protection. It includes a body portion, a retaining member, a capturing and releasing mechanism, a remote control module, and an energy source. The body portion, and the retaining member in a normal position thereof, together form a closed aperture for capturing a D-ring attachment point or other article of attachment hardware. The capturing and release mechanism is operated through the remote control module to free the retaining member so that it can move, in response to energy provided by the energy source, in a direction away from the normal operating position and in an amount such that it no longer closes the aperture, so that the article can escape from the apparatus.
1. An apparatus for providing fall protection to a user, comprising:
a capture and release module having a body supporting a capture and release mechanism, said body and said capture and release mechanism together defining a retaining aperture through said capture and release module for receiving an article of attachment hardware, said capture and release mechanism including a retaining member, said capture and release mechanism in a first configuration thereof being adapted to maintain said retaining member in a normal operating position of said retaining member in which said retaining member closes said retaining aperture, said capture and release mechanism in a second configuration thereof being no longer capable of maintaining said retaining member in said normal operating position, said capture and release module being adapted to permit said retaining member, in said second configuration, to move in a direction away from said normal operating position in an amount such that said retaining member no longer closes said retaining aperture; and
a remote control module having a body separate from the body of said capture and release module, the remote control module for remotely causing a change in said capture and release mechanism from said first configuration into said second configuration in response to user manipulation of said remote control module, wherein said capture and release module further includes an energy source that is enabled by said change to move said retaining member in said direction at least said amount in response to said change.
2. The apparatus of claim 1 , wherein the retaining aperture is maintained in a fixed position relative to the body.
3. The apparatus of claim 1 , further comprising a harness for the user to wear, the harness having one or more lengths of webbing, the capture and release module having at least one permanently closed harness-attachment aperture, wherein one or more of the one or more lengths of webbing pass through the at least one harness-attachment aperture.
4. The apparatus of claim 3 , wherein the retaining aperture is maintained in a fixed position relative to the body.
5. The apparatus of claim 1 , adapted so that at least two distinct actions are required by the user for causing said change.
6. The apparatus of claim 5 , further comprising a harness for the user to wear, the harness having one or more lengths of webbing, the capture and release module having at least one permanently closed harness-attachment aperture, wherein one or more of the one or more lengths of webbing pass through the at least one harness-attachment aperture.
7. The apparatus of claim 5 , wherein the retaining aperture is maintained in a fixed position relative to the body.
8. The apparatus of claim 6 , wherein the retaining aperture is maintained in a fixed position relative to the body.
9. The apparatus of claim 1 , wherein said remote control module includes an elongate linking member linking said remote control module to said capture and release module, said elongate linking member having at least two separate portions, a first of the at least two separate portions which is permitted to move at least a predetermined amount relative to a second of the at least two separate portions before sufficient force can be transmitted from the first of the at least two separate portions to the second of the at least two separate portions to change said capture and release mechanism from said first configuration into said second configuration.
10. The apparatus of claim 9 , adapted so that at least two distinct actions are required by the user for causing said change.
11. The apparatus of claim 10 , further comprising a harness for the user to wear, the harness having one or more lengths of webbing, the capture and release module having at least one permanently closed harness-attachment aperture, wherein one or more of the one or more lengths of webbing pass through the at least one harness-attachment aperture.
12. The apparatus of claim 9 , further comprising a harness for the user to wear, the harness having one or more lengths of webbing, the capture and release module having at least one permanently closed harness-attachment aperture, wherein one or more of the one or more lengths of webbing pass through the at least one harness-attachment aperture.
13. The apparatus of claim 9 , wherein the retaining aperture is maintained in a fixed position relative to the body.
14. The apparatus of claim 1 , wherein said source of energy is one or more springs adapted for first spring-biasing said retaining member relative to said body portion.
15. The apparatus of claim 14 , wherein the retaining aperture is maintained in a fixed position relative to the body.
16. The apparatus of claim 14 , further comprising a harness for the user to wear, the harness having one or more lengths of webbing, the capture and release module having at least one permanently closed harness-attachment aperture, wherein one or more of the one or more lengths of webbing pass through the at least one harness-attachment aperture.
17. The apparatus of claim 16 , wherein the retaining aperture is maintained in a fixed position relative to the body.
18. The apparatus of claim 14 , wherein said remote control module includes an elongate linking member linking said remote control module to said capture and release module, said elongate linking member having at least two separate portions, a first of the at least two separate portions which is permitted to move at least a predetermined amount relative to a second of the at least two separate portions before sufficient force can be transmitted from the first of the at least two separate portions to the second of the at least two separate portions to change said capture and release mechanism from said first configuration into said second configuration.
19. The apparatus of claim 18 , adapted so that at least two distinct actions are required by the user for causing said change.
20. The apparatus of claim 19 , further comprising a harness for the user to wear, the harness having one or more lengths of webbing, the capture and release module having at least one permanently closed harness-attachment aperture, wherein one or more of the one or more lengths of webbing pass through the at least one harness-attachment aperture.
21. The apparatus of claim 14 , adapted so that at least two distinct actions are required by the user for causing said change.
22. The apparatus of claim 21 , further comprising a harness for the user to wear, the harness having one or more lengths of webbing, the capture and release module having at least one permanently closed harness-attachment aperture, wherein one or more of the one or more lengths of webbing pass through the at least one harness-attachment aperture.
23. The apparatus of claim 22 , wherein the retaining aperture is maintained in a fixed position relative to the body.
24. The apparatus of claim 21 , wherein the retaining aperture is maintained in a fixed position relative to the body.
25. The apparatus of claim 18 , further comprising a harness for the user to wear, the harness having one or more lengths of webbing, the capture and release module having at least one permanently closed harness-attachment aperture, wherein one or more of the one or more lengths of webbing pass through the at least one harness-attachment aperture.
