Abstract

A weight bearing fall protection connector includes a first connection member configured to attach the connector to a piece of fall protection equipment, and a second connection member configured to attach the connector to another piece of all equipment, with the connection members fixed to each other to transfer the weight of a worker in a fall event and for movement relative to each other between a ready position and a fall position. The connector further includes a breakable component having a retaining condition wherein the component maintains the members in a ready position and broken condition wherein the component allows the members to move to their fall position. The connector further includes a wireless fall indicator including a wireless transmitter and a switch configured to activate the wireless transmitter in response to movement of the members from the ready position to the fall position.

First claim

The invention claimed is:

1. A weight bearing fall protection connector for connecting one piece of fall protection equipment to another piece of fall protection equipment to transfer a weight of a worker in an event of a fall, the connector comprising:
a first connection member configured to attach the connector to one piece of fall protection equipment;
a second connection member configured to attach the connector to another piece of fall protection equipment, the first and second connection members fixed to each other to transfer the weight of a worker in a fall event and for movement relative to each other between a ready position where the connector has not experienced a fall event while connected to a worker and a fall position where the connector has experienced a fall event while connected to a worker;
a breakable component operably connected to the first and second connection members and having a retaining condition wherein the breakable component maintains the connection members in the ready position and a broken condition wherein the breakable component allows the connection members to move to their fall position after the breakable component has been broken by a weight transfer from a fall event; and
a wireless fall indicator comprising:
a wireless transmitter, and
a switch configured to activate the wireless transmitter in response to movement of the connection members from the ready position to the fall position, the wireless transmitter configured to transmit a wireless signal indicating that a worker has fallen when the wireless transmitter is activated by the switch,
wherein the breakable component is a shear pin that shears in response to a fall event, and wherein the shear pin is received in closely conforming bores formed in the connection members.

2. The weight bearing fall protection connector of claim 1 wherein:
the first connection member comprises a first connection portion to attach the first connection member to one piece of fall protection equipment;
the second connection member comprises a second connection portion to attach the second connection member to another piece of fall protection equipment; and
each of the connection members has a weight transfer portion engaged with the weight transfer portion of the other connection member to transfer the weight of a worker from the first connection member to the second connection member during a fall event.

3. The weight bearing fall protection connector of claim 2 wherein the weight transfer portions are engaged to each other for guided translation relative to each other as the connection members move from the ready position to the fall position, and each of the weight transfer portions has a stop surface that engages another surface to retain the connection members in the fall position.

4. The weight bearing fall protection connector of claim 2 wherein one of the weight transfer portions comprises a bar and the other of the weight transfer portions comprises an opening that receives the bar for sliding movement of the bar in the opening.

5. The weight bearing fall protection connector of claim 4 wherein the bar is a cylindrical shaft and the opening is a cylindrical bore that allow the connection members to swivel relative to each other in the ready position.

6. The weight bearing fall protection connector of claim 2 wherein at least one of the weight transfer portions comprises a collar that engages the other weight transfer portion to retain the connection members in the fall position.

7. The weight bearing fall protection connector of claim 1 wherein the shear pin retains a collar in a fixed position relative to one of the connection members with connection members in the ready position, and wherein the one of the connection members is released by the shear pin for movement relative to the collar in response to a fall event.

8. The weight bearing fall protection connector of claim 1 wherein the switch comprises a pair of electrical contacts that are spaced from each other with the connection members in the ready position and pressed against each other with the connection members in the fall position.

9. The weight bearing fall protection connector of claim 8 wherein:
the first connection member includes a surface that engages one of the pair of electrical contacts as the connection members move from the ready position to the fall position; and
the second connection member includes a surface that engages the other of the pair of electrical contacts as the connection members move from the ready position to the fall position, the engagement of the surfaces with the electrical contacts pressing the contacts against each other with the connection members in the fall position.

10. The weight bearing fall protection connector of claim 1 , wherein at least one of the connection members or the breakable component is configured to generate a magnetic field, and the switch is a magnetic reed switch that is actuated in response to movement of the magnetic field as the connection members move from the ready position to the fall position.

11. The weight bearing fall protection connector of claim 1 wherein the connector is a D-ring connector.

12. The weight bearing fall protection connector of claim 1 wherein the connector is a Snap Hook connector.

13. A weight bearing fall protection connector for connecting one piece of fall protection equipment to another piece of fall protection equipment to transfer a weight of a worker in an event of a fall, the connector comprising:
a first connection member including a first connection portion configured to attach the first connection member to one piece of fall protection equipment;
a second connection member including a second connection portion configured to attach the connector to another piece of fall protection equipment, the first and second connection members fixed to each other to transfer the weight of a worker in a fall event and for movement relative to each other between a ready position where the connector has not experienced a fall event while connected to a worker and a fall position where the connector has experienced a fall event while connected to a worker;
a breakable component operably connected to the first and second connection members and having a retaining condition wherein the breakable component maintains the connection members in the ready position and a broken condition wherein the breakable component allows the connection members to move to their fall position after the breakable component has been broken by a weight transfer from a fall event; and
a wireless fall indicator comprising:
a wireless transmitter, and
a switch configured to activate the wireless transmitter in response to movement of the connection members from the ready position to the fall position, the wireless transmitter configured to transmit a wireless signal indicating that a worker has fallen when the wireless transmitter is activated by the switch; and

wherein:
each of the connection members includes a weight transfer portion engaged with the weight transfer portion of the other connection member to transfer the weight of a worker from the first connection member to the second connection member during a fall event;
each of the weight transfer portions includes a stop surface that engages another surface to retain the connection members in the fall position;
one of the weight transfer portions includes a cylindrical shaft and the other of the weight transfer portions includes a cylindrical bore that receives the shaft for sliding movement of the shaft in the bore and for rotational movement of the shaft in the bore;
the brea
