Embodiments of the present invention relate in general to the field of construction and are particularly useful as an installation aid for installing boards such as drywall and sheetrock.
Many construction jobs require the use of support structures. One such example relates to the installation of various boards such as drywall, sheetrock, plywood, plasterboard, soffit plywood, durock, blueboard, densglass gold, and exterior drywall, particularly at ceiling levels. Do-it-yourselfers and even professionals have been known to attempt to hold drywall up to a ceiling using their heads before securing such boards to a support structure. Such a system works, but it does require some coordination and is an awkward, unprofessional system. Indeed, getting such boards up to ceiling heights can be a particularly difficult task without the right tools.
The use of drywall support devices are known in the art. One such device is a drywall lift. A user loads a sheet of drywall on the drywall lift and then cranks it up to the ceiling. Such devices work well but are often too expensive to purchase for a do-it-yourselfer performing a one-time installation. In addition, even for professionals such drywall lifts can be inconvenient as they take up a lot of room on/in the installer's vehicle/storage area and the time of use per board is greater than is necessary.
Another drywall support apparatus is disclosed in U.S. Pat. No. 6,508,448, issued to Stewart (incorporated by this reference for all purposes). Stewart discloses an adjustable drywall support apparatus for holding a wallboard in place as it is being installed at ceiling level. The Stewart device works well for its intended purpose but such a device is more bulky and complicated to use than it need be, in part due to the ridged design of the support shaft structure.
Interestingly, installers often create their own “Stewart” type devices, called dry-wall jacks, designed specifically for a particular installation site. Such home-made devices are ridged devices typically constructed from wood with the overall height of the jack an inch taller than the height from the floor to the ceiling. Such devices waste material as the jacks are used for that one installation task and then discarded.
The above devices work well for their designed purposes but they do have their design shortcomings. One problem with such prior art devices relates, ironically, to the ridged nature of their construction. Such devices typically use an adjustable structure, such as a telescoping pole, that provides a ridged, straight support system from floor to ceiling. Such devices work well but they are more complicated to use and require more time to use (adjust) per item than is necessary.
What is needed is an improved apparatus that provides for a small, lightweight structure that is easy to store and move that provides a flexible support system that is easy and quick to adjust and use.
Some of the objects and advantages of the invention will now be set forth in the following description, while other objects and advantages of the invention may be obvious from the description, or may be learned through practice of the invention.
Broadly speaking, a principle object of the present invention is to provide an improved apparatus for holding a construction item in a desired position, such apparatus comprising a pressure-plate configured with a pole-ball-socket, a pole-ball-receiver, and a flexible pole section.
Another objective is to provide the above device configured with a plurality of pole sections configured with a latching-device wherein at least one pole section is flexible. The plurality of pole sections are movably associated with each other when the latching-device is not engaged. The plurality of pole sections are secured in place by engaging said latching-device.
For one embodiment of the invention, a pressure-plate-surface of the pressure-plate is configured for being associated with a first-item-surface of the construction-item (such as one side of a board). A second-item-surface (e.g. the opposing surface of such board) is configured for being associated with a first-construction-surface (such as a ceiling). The pressure-plate either comprises an integral pole-ball-socket or is mechanically associated with a pole-ball-socket. Such pole-ball-socket is configured to receive one end of a flexible pole section. The opposing end of such flexible pole section is preferably associated with an end cap suitably configured for being associated with a second-construction-surface (e.g. a floor) in a slip resistant manner. The flexible pole section is configured to be a predefined length. When a plurality of pole sections and latching-device(s) are used, the pole sections are adjusted to the predefined length and then secured by the latching-device.
Typically, the predefined length is about four inches longer than the distance from the first-construction-surface and the second-construction-surface.
At least part of the pole section is made of a strong but flexible material that allows the poles to flex. It should be appreciated that the above described pole-ball-socket/flexible pole configuration allows the pressure-plate-surface to move relative to the pole section so that the pressure-plate-surface maintains a desired orientation relative to the construction-item surface.
For example, suppose the construction-item is a board, and the pressure-plate-surface is a flat surface. As the pole sections flex, the pole-ball-socket moves relative to the pressure-plate-surface so that pole sections extend from the pressure-plate at an angle while the pressure-plate-surface stays flat against the board's surface. Thus, the pole section may extend perpendicularly from the pressure-plate-surface or at an angle from the pressure-plate-surface as desired by the user.
Additional objects and advantages of the present invention are set forth in the detailed description herein or will be apparent to those skilled in the art upon reviewing the detailed description. Also, it should be further appreciated that modifications and variations to the specifically illustrated, referenced, and discussed steps, or features hereof may be practiced in various uses and embodiments of this invention without departing from the spirit and scope thereof, by virtue of the present reference thereto.

The flexible pole sections are configured to be extendable (for multiple pole section configurations) to a predefined length. Typically, the predefined length is about four inches (4″) longer than the distance from the first-construction-site-surface (9) and a second-construction-surface (13), such as floor 13. For the example depicted in
When used to raise a construction item, pressure-plate-surface (7) is associated with one surface of a construction item and then the poles 16 and 18 are extended to the desired height and secured by latching-device (20). While extending the pole sections, apparatus (10) may be held at a angle relative to the second-construction-surface (13) so that the construction item may be raised to the desired height while allowing the pole sections to be extended a distance slightly greater than distance (3) (e.g. the previously described 4 inches). Next, a side pressure is applied to the pole section causing the pole section to flex and allowing end cap (22) to interface with second-construction-surface (13) thereby holding the construction item in place. It should be appreciated that the amount of (and location of) the “flex” depicted in the figures is for illustration purposes only and the actual flex in the pole section(s) may be quite different. For example, both sections may bow to form a uniform arc from surface (13) to surface (9).

Each such pressure-transfer-rail (42) extends from the parabolic section (32) to rail-surface (49) so as to define a substantially flat plain which defines substantially flat pressure-surface (44). Restated, while each pressure-transfer-rail may have different “heights” (the distance from the parabolic section to a predefined point), the rail-surface (49) for each pressure-transfer-rail (42) define a substantially flat support surface with all such support surfaces defining a substantially flat plain along line (45). Pressure-plate (12) may be constructed to have any sized desired to address a particular tasks, however, for the preferred embodiment, each inter-rail space (31) (

Using rails and spokes in such a configuration lowers the weight and cost of pressure-plate (12) by providing hollow sections between the concentric circles (46) and spokes (48).

When latching-lever (88) is pressing against first-pole section (82), second-pole-receiver (84) squeezes together to clamp down on pole-section (16) thereby locking pole-section (16) into a desired position. When latching-lever (88) is moved away from first-pole-receiver (82), second-pole-receiver (84) expends outward for the previously squeezed position thereby allowing pole-section (16) to move.
It should be noted that there are typically one (1) less latching-device than there are pole sections. For example, for a two pole section configuration, there will be one latching device and for a three pole section configuration there will be two latching devices. Each latching device will have the same characteristics but be slightly different diameters for associating with poles of slightly different diameters. When there is only one pole section, such pole section is manufactured to the desired predefined length.
While the present subject matter has been described in detail with respect to specific embodiments thereof, it will be appreciated that those skilled in the art, upon attaining an understanding of the foregoing may readily adapt the present technology for alterations to, variations of, and equivalents to such embodiments. Accordingly, the scope of the present disclosure is by way of example rather than by way of limitation, and the subject disclosure does not preclude inclusion of such modifications, variations, and/or additions to the present subject matter as would be readily apparent to one of ordinary skill in the art.
