- the invention is particularly suited for the use by bricklayers, plasterers, painters and others such as drywall construction workers and workers installing ceiling lights or ceiling panels.
- the above noted endeavors require the workers to work at successively different levels and to have sufficient mobility to be able to move laterally to work zones outside the reach of their arms.
- the above noted stilts eliminate the use scaffolds or ladders which can cumbersome or expensive and time consuming to use.
- Stilts are known that have a certain height requirement and other stilts are known that have extensions built into the same so that different height requirements can be achieved. These extension type of stilts are heavy and are more expensive to obtain and at times still do not reach a certain height requirement.
- An object of the invention is to remedy the above noted problems and shortcomings by providing a simple extension frame that can be inserted between the upper and lower sections of a standard stilt which will enable the workman to reach different heights wherever required. This enables the workman to reach different heights that heretofore were impossible to reach even with stilts that have extension built into them.

- This inventive concept illustrates the versatility of the overall mechanical stilt because the stilt can be adjusted to lengths never before achieved.
Abstract
An extension is provided for a standard mechanical stilt that is interfitted or telescoped between upper frame members and lower frame members of the standard mechanical stilt to thereby greatly increase the desired working length of the mechanical stilt. The extension consists of the same cross-sectional profiles as the standard stilt. The extension member may be interlocked with the standard stilt at any desired length. The extension frame has shock absorbing springs incorporated therein.
Description
- The invention relates to a mechanical stilt or a pair of stilts. The invention is particularly suited for the use by bricklayers, plasterers, painters and others such as drywall construction workers and workers installing ceiling lights or ceiling panels. The above noted endeavors require the workers to work at successively different levels and to have sufficient mobility to be able to move laterally to work zones outside the reach of their arms. The above noted stilts eliminate the use scaffolds or ladders which can cumbersome or expensive and time consuming to use.
- Stilts are known that have a certain height requirement and other stilts are known that have extensions built into the same so that different height requirements can be achieved. These extension type of stilts are heavy and are more expensive to obtain and at times still do not reach a certain height requirement.
- An object of the invention is to remedy the above noted problems and shortcomings by providing a simple extension frame that can be inserted between the upper and lower sections of a standard stilt which will enable the workman to reach different heights wherever required. This enables the workman to reach different heights that heretofore were impossible to reach even with stilts that have extension built into them.

FIG. 1 is a prior art representation of a known stilt; -
FIG. 2 is an exploded view of the inventive concept; -
FIG. 3 shows the extension in a perspective view; -
FIG. 4 illustrates a perspective view of the installed extension. - Fig. Illustrates the prior art device in a right and left presentation. It is well known that mechanical stilts consist of upper 1 and lower 2 frames, respectively. The lower frame member typically has two
foot pads 3 which are hinged at 4 and 5 to thelower frames upper frame members 1. Theupper frame member 2 has afoot platform 6 onto which the worker's foot will be supported when working on a project. There isleg brace 7 which is attached to theupper frame member 2 by way of a legbrace support rod 7 a. Thelower frame members holes upper frame members 1, will be used to secure the upper and lower frame together in an adjusted location by way of thebolts 10 andscrew heads 10 a. Theupper frame member 1 typically has abracket 11 which is located midway between the two opposingbrackets 12. Between the two opposing brackets there are located two andlower springs intermediate bracket 11. These springs act as shock absorbers as the workman moves around his work to different positions or locations and also aid in simulating a regular walk of the workman. The above describes a standard mechanical stilt and will aid in understanding the inventive concept of placing an extension between the upper andlower frame members FIGS. 2-4 and the inventive extension described below will start with the numeral or call-out 20. -
FIG. 2 is an exploded view of theextension 20 prior to an insertion into each of the upper and lower frame members. Theextension 20 has twoupper frame members upper frame members upper frame members holes screws tubes frame members 1. The lower frame members ortubes screws insert frame members upstanding members 1. - The inventive insert has the same shock absorbing system as is found on the prior art stilts. Thus, the
insert 20 has theintermediate bracket 28 and the two opposingbrackets lower springs spring springs -
FIG. 4 shows a perspective view of the inventive insert after having been inserted into a standard stilt including the upper 1 and lower 2 frame members. From thisFIG. 4 it can also be seen that there is quite a considerable range of adjustability obtained with the inventive insert. The insert can first be adjusted by changing the lengths between the lower frame members of the inventive insert relative to the lowerupstanding frame members upper frame members
