Abstract

Embodiments of the disclosure provide a safety rail. The safety rail may include a body disposed on first and second adjustable boots. The first and second adjustable boots may be adapted to secure the safety rail to an excavation support structure. The body may include a lower rail connected to the first and second adjustable boots.

Claims (32)

1. A safety rail, comprising:

a body disposed on first and second adjustable boots adapted to secure the safety rail to an excavation support structure, the body comprising a lower rail connected to the first and second adjustable boots,

wherein the first adjustable boot and the second adjustable boot each comprises:

a first member having a first jaw disposed thereon; a second member having a second jaw disposed thereon; a first tightener disposed through the first member and connected to the second member,

wherein the first tightener is adapted to move the first and second jaws toward one another when actuated in a first direction and away from one another when actuated in a second direction,

a second tightener is disposed through the first jaw,

wherein the first member comprises a connector base, and wherein the connector base and the first jaw are both disposed on one or more supports, and

wherein the second member comprises a slider and the second jaw, the slider being adapted to fit into the first member between the connector base and the first jaw.

2. The safety rail of claim 1 , wherein the body further comprises a first post and a second post disposed on the lower rail, wherein a first sleeve connector is disposed on the first post and a second sleeve connector is disposed on the second post, and wherein each sleeve connector is adapted to be fastened to another sleeve connector via a fastener disposed therethrough.

3. The safety rail of claim 1 , wherein the first tightener moves the first and second jaw toward one another when the first tightener is rotated in the first direction and wherein the first tightener moves the first and second jaw away from one another when the first tightener is rotated in the second direction.

4. A safety rail, comprising:

a body disposed on first and second adjustable boots adapted to secure the safety rail to an excavation support structure, the body comprising a lower rail connected to the first and second adjustable boots;

a first base leg connecting the first adjustable boot to the lower rail; and

a second base leg connecting the second adjustable boot to the lower rail, wherein:

the first and second base legs are disposed between ends of the body,

the first adjustable boot and the second adjustable boot each comprise a first tightener disposed through a first member and connected to a second member, the first tightener being adapted to draw the second member toward the first member when actuated,

the first member comprises a connector base and a first jaw both disposed on one or more supports, a connector disposed on the connector base and adapted to receive one of the first and second base legs, a first plate disposed on the one or more supports proximate the first jaw and opposing the connector base, and a second plate disposed on an opposite side of the one or more supports from the first jaw,

the second member comprises a slider and a second jaw, the slider being adapted to fit into the first member between the connector base and the first jaw, and

the first tightener is adapted to draw the second jaw toward the first jaw when rotated in a first direction and to push the second jaw away from the first jaw when rotated in a second direction.

5. The safety rail of claim 4 , wherein the first tightener is disposed through the second plate of the first member, and wherein the slider is adapted to move back and forth in an opening formed in the first member between the connector base, the one or more supports, and the first plate.

6. A safety rail, comprising:

a body disposed on first and second adjustable boots adapted to secure the safety rail to an excavation support structure, the body comprising a lower rail connected to the first and second adjustable boots;

a first base leg connecting the first adjustable boot to the lower rail; and

a second base leg connecting the second adjustable boot to the lower rail, wherein:

the first and second base legs are disposed between ends of the body,

the first adjustable boot and the second adjustable boot each comprise a first tightener disposed through a first member and connected to a second member, the first tightener being adapted to draw the second member toward the first member when actuated,

the first member comprises a connector base and a first jaw both disposed on one or more supports,

the second member comprises a slider and a second jaw, the slider being adapted to fit into the first member between the connector base and the first jaw,

the first tightener is adapted to draw the second jaw toward the first jaw when rotated in a first direction and to push the second jaw away from the first jaw when rotated in a second direction, and

each of the first and second adjustable boots further comprises a second tightener disposed through the first jaw.

7. The safety rail of claim 1 , wherein the body is capable of withstanding, without failure, a force of about 890 N or more applied to an upper rail of the body.

8. The safety rail of claim 1 , wherein the lower rail is capable of withstanding, without failure, a force of about 666 N or more applied in any downward or outward direction at any point thereon.
