The present invention is generally related to the field of roof installation and repair, and more particularly related to a shingle installation jack device for raising and lowering a walk board via remote control to facilitate efficient shingle installation or repair on a roof of a building or structure. The herein disclosed remote-controlled shingle installation jack device may be utilized as a pair of devices; a first remote-controlled shingle installation jack device is mounted on a first end of a walk board and a second remote-controlled shingle installation jack device is mounted on a second end of a walk board. The shingle installation jack devices may be mounted once at a first roof level, providing support for the walk board. When installation or repair of the shingles is complete at the first level of the roof, the shingle installation jack devices may be operated in tandem to raise the level of the walk board to a second level of the roof. Shingle installation and/or repair may then be carried out at this second roof level without the need to re-mount the walk board supports at the second level. The shingle installation jack devices may also be run in reverse to lower the walk boards.
The herein disclosed shingle installation jack device is capable of continuous movement up and down the roof, allowing for placement of the walk boards at any roof level (or roof height) as desired by a user. In other words, the walk boards may be mechanically raised or lowered to any roof level by the herein disclosed shingle installation jack device, facilitating use with installation of any size or type of roof shingle. The herein disclosed shingle installation jack device may additionally be used for all roof repair or inspection purposes, even if they do not involve shingles. For example, the herein disclosed shingle installation jack devices may be advantageously utilized during chimney repair on buildings or structures having a slanted roof.
An exemplary embodiment of the herein disclosed shingle installation device comprises: a frame having a bottom member for anchoring a pulley, a first slider member, a second slider member, and a top member for supporting a walk board and for anchoring a first end of a spring, wherein the top member is in parallel with the bottom member and the first slider member is in parallel with the second slider member; a mounting assembly for anchoring a winch motor, wherein the mounting assembly has an upper surface for anchoring a second end of the spring and a lower surface for anchoring an eye bolt; a cable having an adjustable effective length running from the winch motor, through the pulley, and back to the eye bolt, wherein the adjustable effective length of the cable is controllable by the winch motor; and the spring spanning from the top member of the frame to the upper surface of the mounting assembly.

Most single-family houses have slanted roofs lined with shingles (or tiles) for protecting the roof from environmental elements such as rain and snow. Other types of building or structures may also utilize such a slanted roof design, lined with shingles for protection from the elements. Shingles are generally installed manually by workers or contractors physically located on the slanted roof while they work. Because the roofs are slanted, walk boards are temporality positioned on the roof to provide a supporting surface for the workers or contractors to walk on, or sit or kneel on, during their work.
Standard procedure for roof work currently involves mounting the walk board(s) at a particular roof level (or roof height) so that the workers and contractors may carry out their installation or repair work at this roof level. When work at this level is complete, the walk boards must be re-mounted at a second level before installation or repair work can commence at this second level. This procedure may have to be repeated many times in order to complete shingle installation or repair over an entire roof. The process of re-mounting the walk boards securely at various roof levels is important for safety of the workers and contractors, but the process is tedious and time consuming. And if the re-mounting is done incorrectly, the walk boards may be unsecure and thus dangerous for the workers and contractors. This standard procedure is not very efficient.
There is a demonstrated need, therefore, for a device that may eliminate the need to continuously re-mount walk boards during installation or repair of roof shingles. The present invention provides such a device than may be utilized to facilitate installation or repair of roof shingles at various roof levels without the need to re-mount the walk boards.
The present invention is generally related to the field of roof installation and repair, and more particularly related to a shingle installation jack device for raising and lowering a walk board via remote control to facilitate efficient shingle installation or repair on a roof of a building or structure. The herein disclosed remote-controlled shingle installation jack device is, in a preferred embodiment, intended to be utilized as a pair of devices with a first remote-controlled shingle installation jack device mounted on a first end of a walk board and a second remote-controlled shingle installation jack device mounted on a second end of a walk board.
An exemplary embodiment of the herein disclosed shingle installation device comprises: a frame having a bottom member for anchoring a pulley, a first slider member, a second slider member, and a top member for supporting a walk board and for anchoring a first end of a spring, wherein the top member is in parallel with the bottom member and the first slider member is in parallel with the second slider member; a mounting assembly for anchoring a winch motor, wherein the mounting assembly has an upper surface for anchoring a second end of the spring and a lower surface for anchoring an eye bolt; a cable having an adjustable effective length running from the winch motor, through the pulley, and back to the eye bolt, wherein the adjustable effective length of the cable is controllable by the winch motor; and the spring spanning from the top member of the frame to the upper surface of the mounting assembly.
Throughout this specification the term “shingle” will mostly be used to refer to the object(s) that are to be installed or repaired on a slanted roof of a building or structure. As used herein, the term shingle is intended to include any type of roofing material, such as tiles or beams for example, that may be installed or repaired on a roof.
