AI Technical Summary

Technical Problem

Existing ladders lack convenient solutions to enhance stability and prevent tipping when the center of mass shifts, posing a safety concern for users, particularly those afraid of heights.

Method used

An additional support mechanism, including a foldable pivot and telescoping structure, is attached to the ladder to provide enhanced stability by acting as an extra 'leg' and prevent tipping, featuring a universal joint and clamp for secure attachment.

Benefits of technology

The solution increases ladder stability, reducing the risk of falling and creating a safer working environment by extending the base, while being portable and easy to attach.

Description

[0001] Convenient Ladder Safety Support

[0002] Background

[0003] Many people today are scared of heights, especially when climbing ladders. One safety concern about climbing ladders is that if the center of mass shifts off the ladder, the ladder may fall due to insufficient counter force. Currently, there are no convenient solutions to making ladders safer for people going up on tall places.

[0004] Description

[0005] This invention adds an additional support to a ladder which will provide better stability and reduce the risk of a ladder falling down. Ultimately, this invention allows for workers to work in a safer environment. This increases the length of the base, decreasing the chance of being tipped over. This invention is also easily attached and is easy to transport.

[0006] Figure 1 shows the general idea of how the support will make the ladder more stable. The ladder in this case has a support (labeled 1) that is foldable by the pivot (labeled 2) to adjust for different situations. The support will protrude from the ladder providing an extra “leg” of the ladder preventing the ladder from tipping in the direction in which the support protrudes from.

[0007] Figure 2 shows the foldable pivot of the support allowing to adjust the support for different circumstances. In the diagram we used a universal joint (labeled 1). However, any joint can be used. There is also a clamp that clamps down on the side of the ladder (labeled 2), providing stability for the support and not allowing it to slide off the ladder.

[0008] Figure 3 shows the supporting leg can become longer or shorter. In the diagram, we illustrated using the telescoping structure, as shown with the partitions labelled 1 and 2. However, in practice, any folding mechanism can work. This allows for the invention to be portable and convenient.

[0009] On top of that, you can add the rod to the left, right, or both sides of the ladder, and extend to any angle and direction. The user will also be able to attach as many rods to the ladder as they need in order to feel safe enough in their working situation.

Claims

Claims1) On any ladder, there is a safety mechanism that involves a rod or post extending from a ladder adding additional base support to the ladder2) The combination defined in claim 1 where the support may have a folding mechanism or other mechanism making the rod length smaller and easier to transport3) The combination defined in claim 1 where the support may be built into the ladder4) The combination defined in claim 1 where the support is clamped to the ladder5) The combination defined in claim 1 where the support uses any different pivot mechanism.6) The combination defined in claim 1 where different types of clamp can be used
