Abstract

Connectors for coupling fall arresting devices to a safety harness. The connectors may include a first pin configured to lock into a first side of a base portion using one or more locking mechanisms. The first pin may be used to engage with one or more fall arresting devices to attach the one or more fall arresting devices to the connector. In some such examples, the locking mechanisms may be positioned within interior portions of the first side of the connector so as to allow the one or more fall arresting devices to pivot freely about the ends of the connector. In some examples, the connectors may include a second pin configured to lock into a second side of the base portion using one or more locking mechanisms. The second pin may be used to conveniently and releasably attached the connector to a safety harness of a worker.

First claim

What is claimed is:

1. A connector for coupling fall arresting devices to a safety harness, the connector comprising:
a pin having a locking notch; and
a base defining a first side and a central longitudinal axis, the first side of the base comprising: a plurality of first-side receiving portions extending outwardly from the base and spaced apart from each other to define a plurality of first-side openings for receiving one or more connection points of respective ones of the fall arresting devices, the plurality of first-side receiving portions comprising:
a first receiving portion defining a first receiving channel, the first receiving portion defining a first end of the first side;
a second receiving portion defining a second receiving channel, the second receiving portion defining a second end of the first side; and
a third receiving portion defining a third receiving channel, the third receiving portion positioned between the first and second receiving portions, the pin slidably connected to the plurality of first-side receiving portions and spanning the plurality of first-side openings and extending through the first, second, and third receiving channels when the pin is in a fully closed configuration; and
a locking mechanism connected to the third receiving portion, the locking mechanism configured to releasably engage with the locking notch of the pin when the pin is in the fully closed configuration to prevent the pin from being slidably withdrawn through the third receiving channel,
wherein the locking notch comprises a first locking notch defined along a shaft of the pin, the shaft of the pin further defining a second locking notch separate and distinct from the first locking notch, the locking mechanism configured to releasably engage with the second locking notch of the pin when the pin is in a partially closed configuration to prevent the pin from being slidably withdrawn through the third receiving channel so that the pin spans a first opening of the plurality of first-side openings defined by the first and third receiving portions but not a second opening of the plurality of first-side openings defined by the second and third receiving portions; and
wherein the first opening and second opening are adjacent to the third receiving portion and do not extend beyond the central longitudinal axis of the base.

2. The connector of claim 1 , wherein the locking mechanism comprises a first locking mechanism, the connector further comprising a second locking mechanism connected to one of the plurality of first-side receiving portions.

3. The connector of claim 2 , wherein the plurality of first-side receiving portions comprises a fourth receiving portion defining a fourth receiving channel, the fourth receiving portion positioned between the third and second receiving portions, the fourth receiving portion comprising the second locking mechanism.

4. The connector of claim 1 , wherein the first receiving portion defines a lateral channel extending substantially perpendicular to the first receiving channel, the pin comprising a shaft that defines a longitudinal slot extending along a portion of the shaft, the connector further comprising an alignment pin received within the lateral channel and the longitudinal slot, the alignment pin configured to prevent a rotation of the pin within the first receiving channel.

5. The connector of claim 4 , wherein the alignment pin prevents the pin from being removed from the base.

6. The connector of claim 1 , wherein the pin comprises a first pin, the locking notch comprises a first locking notch, and the locking mechanism comprises a first locking mechanism, the base defining a second side opposite the first side, wherein the connector further comprises a second pin comprising a shaft defining a second locking notch, and wherein the second side of the base comprises:
a fourth receiving portion defining a fourth receiving channel;
a fifth receiving portion defining a fifth receiving channel, the fourth and fifth receiving portions separated from each other to define a second-side opening, the second pin slidably connected to the fourth and fifth receiving portions, the second pin spanning the second-side opening and extending through the fourth and fifth receiving channels when the second pin is in a fully closed configuration; and
a second locking mechanism connected to the fourth receiving portion, the second locking mechanism configured to releasably engage with the second locking notch of the second pin when the second pin is in the fully closed configuration to prevent the second pin from being slidably withdrawn through the fourth receiving channel.

7. The connector of claim 6 , further comprising a third locking mechanism connected to the fifth receiving portion, the shaft of the second pin defining a third locking notch separate and distinct from the second locking notch, the third locking mechanism configured to releasably engage with the third locking notch of the second pin when the second pin is in the fully closed configuration to prevent the second pin from being slidably withdrawn through the fifth receiving channel.

8. The connector of claim 6 , wherein the fourth receiving portion defines a lateral channel extending substantially perpendicular to the fourth receiving channel, the shaft of the second pin defines a longitudinal slot extending along a portion of the shaft, the connector further comprising an alignment pin received within the lateral channel and the longitudinal slot, the alignment pin configured to prevent a rotation of the second pin within the fourth receiving channel.

9. The connector of claim 8 , wherein the alignment pin prevents the second pin from being removed from the base.

10. A system comprising:
a safety harness comprising a strong point for connecting the safety harness to additional safety equipment; at least one fall arresting device, each fall arresting device comprising a connection point; and a connector comprising:
a pin having a locking notch; and
a base defining a first side and a central longitudinal axis, the first side of the base comprising: a plurality of first-side receiving portions extending outwardly from the base and spaced apart from each other to define a plurality of first-side openings for receiving one or more connection points of respective ones of the fall arresting devices, the plurality of first-side receiving portions comprising:
a first receiving portion defining a first receiving channel, the first receiving portion defining a first end of the first side;
a second receiving portion defining a second receiving channel, the second receiving portion defining a second end of the first side; and
a third receiving portion defining a third receiving channel, the third receiving portion positioned between the first and second receiving portions, the pin slidably connected to the plurality of first-side receiving portions and spanning the plurality of first-side openings and extending through the first, second, and third receiving channels when the pin is in a fully closed configuration; and
a locking mechanism connected to the third receiving portion, the locking mechanism configured to releasably engage with the locking notch of the pin when the pin is in the fully closed configuration to prevent the pin from being slidably withdrawn through the third receiving channel,
the connection point of the at least one fall arresting device received by one of the plurality of first-side openings on the first side of the connector, wherein the pin, when in the fully closed configuration, connects the connection point to the connector to prevent the at least one fall arresting device from being disconnected from the c
