ADJUSTABLE LIFT TABLE
A table lift having a base and a lift attached to the base for movement between a lowered position to a raised position for installation of articles. A platform pivotally attaches to the lift for movement of the platform between a generally horizontal position and an inclined position. The platform is sized and shaped to receive at least one article.

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCHNot Applicable.
BACKGROUND OF THE INVENTIONLift tables are presently used for transporting and lifting articles and materials. In particular, lift tables are typically used to transport and lift large panels, such as paneling or drywall by tradesperson such as masons, carpenters, painters, carpet layers, roofers, electricians, plumbers, HVAC technicians, utility workers, and the like.
However, existing lift tables have substantial shortcomings and drawbacks. For example, many large panels are too wide to pass through standard doorways and passageways while resting horizontally on lift tables. As a result, large panels must be manually carried to the location of installation before the lift table can be used. This exposes tradesperson to unnecessary safety risks and injury.
Accordingly, a need exists for a lift table that can position a large panel between a generally horizontal lift position to an inclined position for passage through doorways, hallways, and other smaller openings and passageways.

DETAILED DESCRIPTIONThe following detailed description illustrates the invention by way of example and not by way of limitation. The description clearly enables one skilled in the art to make and use the invention, describes several embodiments, adaptations, variations, alternatives, and uses of the invention, including what is presently believed to be the best mode of carrying out the invention. Additionally, it is to be understood that the invention is not limited in its application to the details of construction and the arrangements of components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced or being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting.
As shown in
The base 12 is a generally rectangular plate having four rollers 20 mounted generally at each respective corner of a bottom surface 22. Four legs 14 extend upwardly from the upper surface 24 of the base 12 and attach to the scissor lift 16 at respective corners. Braces 26 attach between the legs 14 and the base 12 to provide additional support to the legs 14. The base 12 includes an extended portion 28 that extends a predetermined distance beyond the footprint of the legs 14 and scissor lift 16, such as about 25% of the width of the base 12. The extended portion 28 acts as a stop for the movement of the platform 18 to the inclined position and provides support to the platform 18 when at the inclined transit position (
The scissor lift 16 includes a lower frame 30 attached to the legs 14 and an upper frame 32 pivotally attached to the platform 18. A pair of first arms 34 and a pair of second arms 36 are moveably connected between the lower frame 30 and the upper frame 32 to move between the lowered position (
The platform 18 is a generally rectangular plate with a stop 46 extending perpendicularly upward from the plate from the end corresponding to the extended portion 28 of the base 12 (
In operation, the user places a panel on the platform 18 while in the inclined position (
Changes can be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
