Abstract

The present invention discloses a device and method that allows the installation of construction materials, such as drywall, by a single person.
The device comprises an extension (or hoist) section coupled at one end to a support which can receive and support a piece of drywall during installation. The extension section is further coupled to a base portion at the end opposite to the support. The base portion includes a pivot feature that serves to lift the drywall once it has been positioned on the support. The extension is adjustable to install drywall on a stud wall at various heights. Advantageously, the device is lightweight, easily transportable and easy to use. The device's convenient design enables its utilization immediately upon reaching a construction site.

Claims

1. A device for holding and positioning construction materials, comprising:
A support 30 including a horizontally projecting support bearing flange 34 and a vertically projecting pusher flange 32 for pushing against the construction material;
An extension section 12 comprising an elongate tubular member 14 and a shaft member 16 telescopically disposed in said tubular member 14; and A base portion 50 including a pivot feature 55 that serves to lift the construction material once it has been placed on said support 30 for positioning against a wall.

2. A device as defined in claim 1, wherein said tubular member 14 and said shaft member 16 further comprise orifices allowing said device to be secured at various heights through the use of a locking mechanism 20.

3. A device as defined in claim 2, wherein said locking mechanism is a pin, nail or screw.

4. A device as defined in claim 1 or 2, wherein said base portion 50 further comprises a support plaque 74 oriented at an approximate right angle relative to said pivot feature 55, said support plaque 74 being flat and extending on either side of said pivot feature 55.

5. A device as defined in claim 4, wherein said pivot feature 55 comprises an elevation element 70 that is disposed at a distance that is approximately 1/3rd the distance from said extension section 12 and approximately 2/3rd the distance from the proximal end of said pivot feature 55.

6. A device as defined in claim 5, wherein the bottom end of said tubular member 14 is curved and rests within a curved cavity carved in a metal block 80.

7. A device as defined in claim 6, further comprising retention means between said extension section 12 and said base portion 50 in order to prevent said extension section 12 from rocking about.

8. A device as defined in claim 7, wherein said retention means is a spring.

9. A device as defined in any one of claims 1-8, which can raise construction materials from a height of approximately 42" to a height of approximately 60".

10. A device as defined in claim 9, which has a useful charge of approximately 500 lbs.

11. A device as defined in any one of claims 1-10, which is made of iron.

12. A device for holding and positioning construction materials, comprising:
A support 30 including a horizontally projecting support bearing flange 34 having dimensions of approximately 3" x 8" x 1/4" and a vertically projecting pusher flange 32 for pushing against the construction material having dimensions of approximately 12 x 8" 1/8";
An extension section 12 comprising an elongate tubular member 14 having a length of approximately 42" and a diameter of approximately 3/4", and a shaft member 16 having a length of approximately 32" and a diameter of approximately 5/8" telescopically disposed in said tubular member 14; and A base portion 50 including a pivot feature 55 that serves to lift the construction material once it has been placed on said support 30 for positioning against a wall.

13. A device as defined in claim 12, wherein said tubular member 14 and said shaft member 16 further comprise orifices that are approximately 1/4 in size and that are spaced apart at a distance of approximately 1/8", allowing said device to be secured at various heights through the use of a locking'mechanism 20.

14. A device as defined in claim 13, wherein said locking mechanism is a pin and has a length of approximately 1 1/2' and a diameter of approximately 1/4.

15. A device as defined in any one of claims 12-14, wherein said base portion 50 further comprises a support plaque 74 oriented at an approximate right angle relative to said pivot feature 55, said support plaque 74 being flat and extending on either side of said pivot feature 55 and having dimensions of approximately 8"
x 2"
x 1/4".

16. A device as defined in claim 15, wherein said pivot feature 55 comprises an elevation element 70 having dimensions of approximately 2" x 2" x 3/4"
disposed at a distance that is approximately 1/3rd the distance from said extension section 12 and approximately 2/3rd the distance from the proximal end of said pivot feature 55.

17. A device as defined in claim 16, wherein said elevation element 70 is made of iron.

18. A device as defined in any one of claims 12-17, wherein said pivot feature 55 includes two elongate side members 58 that are approximately 16" in length and 1/2" in width disposed at an approximately right angle relative to an upper member 56 that is approximately 16" in length and 2" in width and which together create a "U"-type bar.

19. A device as defined in claim 18, wherein said elongate side members 58 and said upper member 56 are made of iron and have a thickness of approximately 3/16".

20. A method of installing a construction material at an elevation comprising use of a device as defined in any one of claims 1-19.

21. A method as defined in claim 20, wherein said construction material is drywall.
