BACKGROUND OF THE INVENTION
Various types of height adjustable sheetrock lifting devices are known in the prior art. However, what is needed and what the present device provides is a sheetrock lifting device with a telescoping tube which is extended and retracted with either a battery operated winch or a manual winch, each having a respective pulley mechanism. The sheetrock lifting device should also include a drywall frame attached to the telescoping tube to secure a panel of drywall to be lifted or lowered by the device. The device should have extra support provided by a pair of support rods and a pair of stabilizing beams.
FIELD OF THE INVENTION
The present invention relates to a height adjustable drywall device, and more particularly, to a sheetrock lifting device which is electrically and alternately manually operational.
SUMMARY OF THE INVENTION
The general purpose of the present sheetrock lifting device, described subsequently in greater detail, is to provide a sheetrock lifting device which has many novel features that result in a sheetrock lifting device which is not anticipated, rendered obvious, suggested, or even implied by prior art, either alone or in combination thereof.
To accomplish this, the present sheetrock lifting device provides both electrical and manual operations. The instant device includes a parallelepiped wheeled base with a parallelepiped protrusion centrally disposed on a front side thereof and coplanar with the base. The protrusion has a width smaller than a width of the base thereof. A pair of parallelepiped stanchions is disposed on a top side of the base proximal a rear side thereof. Each of the pair of stanchions has an upper wall, a lower wall, a rearward wall, a forward wall, and an interior wall. A pair of support rods connects a top wall of the protrusion with the interior walls of the stanchions to add extra support for the device. A pair of parallelepiped stabilizing beams is centrally disposed in a position parallel to each other on the base top side between the stanchions. The pair of stabilizing beams has an internal wall and a height greater than a height of the stanchions. A cylindrical telescoping tube is centrally disposed on the top side of the base between the stabilizing beams. The telescoping tube has a ring disposed on an upper portion thereof.
A U-shaped pulley arm is disposed on a top section of the stabilizing beams with a pulley being disposed on an outer end of the pulley arm. An electric winch is disposed on the internal walls of the pair of stabilizing beams proximal the upper walls. The electric winch comprises a battery which is disposed within one of the pair of stanchions and is in operational communication with an on-off switch disposed on the stanchion proximal the electric winch. The engagement of the electric winch is configured to lower and alternately raise the telescoping tube. A pulley cable extends from the ring to the electric winch and is rotationally engagable with the pulley.
An I-shaped drywall frame has a parallelepiped crossmember with an outer edge and an inner edge. An attachment piece attaches the crossmember to the telescoping tube. A parallelepiped end member is disposed on each of an external end of the crossmember. A plurality of vertically disposed nails is on each of the end members.
The present device also includes a manual disposed on the upper wall of the stanchion opposite the stanchion housing the battery. The manual winch comprises a cable with an outer end to which a cable hook is disposed. The cable hook is engageable to the ring. The rotation of the manual winch is configured to raise and alternately lower the telescoping tube.
Thus has been broadly outlined the more important features of the present sheetrock lifting device so 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.

The base 20 has a front side 22, rear side 24, left side 26, right side 28, a top side 30, a bottom side 32, and a parallelepiped protrusion 34 centrally disposed on the front side 22. The protrusion 34 has a front portion 36, a rear portion 38 attached to the base 20, a top wall 40, and a bottom wall 42. The protrusion 34 is coplanar with the base and further has a width smaller than a width of the base thereof. A plurality of locking caster wheels 44 is disposed on each of the bottom side 32 of the base 10 and the bottom wall 42 of the protrusion 34 proximal the front portion 36.
A pair of parallelepiped stanchions 46 are disposed on the top side 30 proximal the rear side 24 in a position parallel to each other and proximal the respective right side 26 and left side 28. Each of the pair of stanchions 46 has an upper wall 48, a lower wall 50, a rearward wall 52, a forward wall 54, and an interior wall 56. A pair of support rods 58, each rod 58 has a first end 60 centrally disposed on the top wall 40 and a second end 62 disposed on the interior wall 56 proximal the upper wall 48 of the respective stanchion 52.
A pair of parallelepiped stabilizing beams 64 is centrally disposed in a position parallel to each other on the top side 30 between the pair of stanchions 52. The pair of stabilizing beams 64 has an internal wall 66 and a height greater than a height of the stanchions 52.
A cylindrical telescoping tube 68 is centrally disposed on the top side 30 of the base 20 between the pair of stabilizing beams 64 in a position parallel to the stabilizing beams 64. The telescoping tube 68 has an upper portion 70. A ring 72 is disposed on the upper portion 70 in a position parallel to the upper portion 70.
A U-shaped pulley arm 74 is disposed on a top section 76 of the stabilizing beams 64 in a position substantially perpendicular to the stabilizing beams 64. A pulley 78 is disposed on an outer end 80 of the pulley arm 74. An electric winch 82 is disposed on the internal walls 66 of the pair of stabilizing beams 64 proximal the upper walls 48 of the stanchions 46 on a same side of the stabilizing beams 64 as the pulley arm 74. The electric winch 82 comprises a battery 84 which is disposed within one of the pair of stanchions 46. The battery 84 is in operational communication with the electric winch 82. The engagement of the electric winch 82 is configured to lower and alternately raise the telescoping tube 68. A pulley cable 86 is rotationally engagable with the pulley 78.
