Abstract

Claims (16)

1. A safety attachment which is used to stabilize a straight ladder or an extension ladder, comprising:

a main body, which contains an upper portion and a lower portion, the upper portion and the lower portion are connected to each other; the upper portion has two connecting bars that parallel to each other, and a hook is fixed to an end of the connecting bars respectively to let the upper portion be attached to a first horizontal bar on the ladder, which is used to step on; the lower portion has two stabilizing bars, and a stabilizer is attached on an end of the stabilizing bars respectively to let the lower portion stably contact ground surface;

a plate, which is fixed on the main body, and covers a portion of surface of both the upper portion and the lower portion, and a first loop is fixed on the plate; and

at least one rope, which has one connector located on both ends of the rope respectively, and one of the connectors is used to detachably attach to the first loop to let the rope connect to the main body, another one of connectors is used to detachably attach to a second horizontal bar on the ladder to let the rope connect to the ladder, wherein each of the connectors contains a first lock structure to prevent the connectors to easily disconnect with the first loop and the second horizontal bar, wherein each of the hooks contains a second lock structure to prevent the hooks to easily disconnect with the first horizontal bar.

2. The safety attachment of claim 1 , wherein each of the stabilizing bars is connected to one of the connecting bars located on same side, and there is an angle between the stabilizing bar and the connecting bar, the angle is between 120 degrees and 180 degrees.

3. The safety attachment of claim 2 , wherein the first loop is located at the location on the plate which corresponding to center of outer surface of the main body.

4. The safety attachment of claim 2 , wherein the main body further comprising multiple second loops, the second loops are located on same side of the main body with the first loop, and the first loop is located at the location on the plate which corresponding to center of outer surface of the main body, and the second loops are located at outer surface of the stabilizing bars respectively.

5. The safety attachment of claim 4 , wherein the amount of the rope is corresponding to the amount of the first loop and the second loops, and one of the ropes has one end detachably attaches to the second horizontal bar, another end detachably attaches to the first loop, and each of the other ropes have one end detachably attaches to a third horizontal bar on the ladder, another end respectively and detachably attaches to the second loops.

6. The safety attachment of claim 5 , wherein each of the connectors contains a first lock structure to prevent the connectors to easily disconnect with the first loop, the second loops, the second horizontal bar and the third horizontal bar.

7. The safety attachment of claim 6 , wherein each of the hooks contains a second lock structure to prevent the hooks to easily disconnect with the first horizontal bar.

8. The safety attachment of claim 7 , wherein the stabilizers are rubbers, which covers the end of the stabilizing bars, or sharp objects which are used to insert into the ground surface for stabilizing the main body.

9. The safety attachment of claim 8 , when the stabilizers are the sharp objects, the safety attachment further comprise a protective cover to cover on each of the sharp objects to prevent the sharp objects cause damage to other structure or people.

10. The safety attachment of claim 1 , wherein the stabilizers are rubbers, which cover the end of the stabilizing bars, or sharp objects which are used to insert into the ground surface for stabilizing the main body.

11. The safety attachment of claim 10 , when the stabilizers are the sharp objects, the safety attachment further comprise a protective cover to cover on each of the sharp objects to prevent the sharp objects cause damage to other structure or people.

12. The safety attachment of claim 1 , wherein the main body and the plate are constructed of aluminum alloy 6063 or aluminum alloy 6061.

13. The safety attachment of claim 1 , wherein the first loop is constructed of aluminum.
