1. Field of the Invention
The present invention relates to support devices and more particularly pertains to a new support device for supporting both legs of a ladder when the ladder is being used on stairs.
2. Description of the Prior Art
The use of support devices, and those for supporting ladders, is known in the prior art. While these devices fulfill their respective, particular objectives and requirements, the need remains for a device that includes particular adjustment means for allowing a ladder to be positioned on stairs having different inclines. Further, the device should include means to prevent movement of the device relative to the stairs and to ensure that the ladder does not slide off of the device.
The present invention meets the needs presented above by generally comprising a panel that has a top side, a bottom side, a first end, a second end, a first lateral side and a second lateral side. Each of a pair of lips is attached to and extends upwardly from the top side and each is coextensive with one of the first and second lateral sides. A vertical support is hingedly coupled to the bottom side and is positioned adjacent to the first end. The panel is substantially horizontally orientated when the vertical support is vertically orientated. The bottom side of the panel adjacent to the second is positioned on a step and the vertical support adjusted to horizontally orientate the panel. A ladder is then positioned on and supported by the panel.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the invention, along with the various features of novelty which characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The invention will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
A vertical support 28 is hingedly coupled to the bottom side 16 and is positioned adjacent to the first end 18. The panel 12 is substantially horizontally orientated when the vertical support 28 is vertically orientated. The vertical support 28 is telescoping and has a selectively adjustable height. The vertical support 28 includes a first leg 30 and a second leg 32. Each of the first 30 and second 32 legs has a bottom end 34 and a top end 36. The bottom ends 34 are hingedly coupled to the bottom side 16 and each is positioned adjacent to one of the first 22 and second 24 lateral edges. A plurality of rods 38 is attached to and extends between the first 30 and second 32 legs. The rods 38 each define a foot step for climbing the vertical support 28.
A planar base 40 is attached to the bottom ends 34 of the first 30 and second 32 legs. The base 40 lies in a plane orientated perpendicular to a longitudinal axis of the first leg 30. A locking member 42 is positioned on the panel 12 and is configured to releasably lock the base 40 to the second end 20 of the panel 12 so that the first 30 and second 32 legs extend along the bottom side 16 of the panel 12 in a stored position. The locking member 42 includes at least one pin slidably coupled to the panel and is extendable through an aperture 44 in the base 40 when a plane of the base 40 is orientated substantially perpendicular to a plane of the panel 12.
A third leg 46 and a fourth leg 48 are provided. Each of the third 46 and fourth 48 legs has an upper end 50 and a lower end 52. Each of the upper ends 50 is hingedly coupled to the bottom side 16 of the panel 12. The third 44 and fourth 48 legs are spaced between 4 inches and 12 inches from the second end 20 of the panel 12. Each of the third 46 and fourth 48 legs is telescopic and has a selectively adjustable height. Pins 54 extended through the first 30, second 32, third 46 and fourth 48 legs are used to lock each at a selected height. A brace 56 is attached to the vertical support 28. Each of the lower ends 52 of the third 46 and fourth 48 legs is positionable on the brace 56. The third 46 and fourth 48 legs form an angle less than 50 degrees with the panel 12 when the lower ends 52 are positioned on the brace 56. In this manner, the third 46 and fourth 48 legs may be used as stabilizers for the apparatus 10, though they may also be used as conventional legs to increase and overall height of the apparatus 10.
A pair of catches 58 is attached to the panel 12. Each of the catches 58 is attached to one of the first 22 and second 24 lateral sides. Each of the catches 58 is positioned below a plane of the bottom side 16 and extends toward the second end 20. The catches 58 are positioned between the second end 20 and the upper ends 50 of the third 46 and fourth 48 legs.
A plate 60 is removably positionable on the top side 14 of the panel 12. The plate 60 extends from a first of the lips 26 to a second of the lips 27 and extends from the first end 18 to the second end 20. The plate 60 is positioned on the panel 12 to define a platform when a person wishes to stand on the panel 12 itself and not use a ladder 8. The plate 60 preferably has a height equal to the height of the lips 26, 27 and will prevent a person from tripping on the lips 26, 27.
In use, the bottom side 16 of the panel 12 adjacent to the second is positioned on a step 9 and the vertical support 28 adjusted to horizontally orientate the panel 12. The catches 58 are abutted against a step 9 to laterally stabilize the apparatus 10. A ladder 8 is positioned on the top side 14 and may be abutted against one of the lips 26, 27 to prevent the sliding of the ladder 8 off of the panel 12.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
