Description
BACKGROUND OF THE INVENTION
(a) Field of the Invention

This invention relates to a liner for covering an aerial lift basket and more particularly, but not by way of limitation, to a disposable plastic liner used for covering a platform floor and an inside and outside of four sides of a frame of a lift basket. The lift basket is used in painting and drywall applications.


(b) Discussion of Prior Art

Heretofore, during painting and drywall applications, using an aerial lift basket, strippable coating, tarps, paint cloths, and tape have been used to protect the lift basket from overspray. The invention eliminates the need for using the above mentioned protective items along with objects and advantages as disclosed herein.


SUMMARY OF THE INVENTION

In view of the foregoing, it is a primary objective of the subject invention to provide a light weight, plastic, disposable basket liner to cover an aerial lift basket, with open top, and protect the lift basket from paint and drywall overspray.


Another object of the invention is the plastic liner eliminates the need for using tarps, paint cloths, tape and strippable coatings, when using an aerial lift basket.


Still another object of the invention is the liner is dimensioned to cover different sizes and shapes of lift baskets. The liner covers a platform floor and an inside and outside of a frame of the lift basket. The liner also includes a removable door cover used to cover a hinged door mounted on a hinged door frame or cover an open door frame on the lift basket.


The subject invention includes a light weight plastic liner adapted for receipt over an aerial lift basket. The liner includes a floor cover and four side covers for covering an inside and an outside of four sides of a frame on the lift basket. Also, the liner includes a removable door cover for covering a hinged door or entrance opening on the lift basket. Further, the liner includes a bungee cord in a bottom seam of the four side covers for holding the liner in place on a bottom of the lift basket.


These and other objects of the present invention will become apparent to those familiar with the use of different types of lift platforms and paint and drywall applications when reviewing the following detailed description, showing novel construction and elements as described, and more particularly defined by the claims, it being understood that changes in the embodiments to the disclosed invention are meant to be included as coming within the scope of the claims, except insofar as they may be precluded by the prior art.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In FIGS. 1 and 2, a perspective view of the subject disposable plastic liner is shown having general reference numeral 10. As mentioned above, the liner 10 is used to cover frames of an aerial lift basket, having general reference numeral 11, from paint and drywall over spray. The aerial lift basket 11 includes an open top for an operator to stand on the lift basket for operating spray equipment.


The lift basket 11 includes a platform floor 12, a first side frame 14, a second side frame 16, a front frame 20, and a hinged entrance door frame 20A, with a hinged door 21 mounted on the hinged entrance door frame 20A. While the hinged door frame 20 and hinged door 21 are shown in the drawing, it should be kept in mind, depending on the manufacture of the lift basket 11 and a width of the platform floor, a chain or a hinged horizontal bar can be used equally well for entry into the aerial lift basket 11. Also, on smaller lift baskets 11, the basket can have an open door entrance, without a hinged door.


The frames are typically 3 to 4 feet in height. The lift basket 11 is mounted on top of a wheel mounted boom or scissor lift 22. The scissor lift 22 is used to raise and lower the platform floor 12 during the painting and drywall applications.


During the installation of the plastic liner 10, the liner is placed on top of the lift basket 11 and unfolded to cover the basket frames. A platform floor cover 24, shown in black, is first laid on top of the platform floor 12.


Next, an entrance door outside cover 23 and an entrance inside cover 25, having an entrance door opening centered thereon, are used to cover opposite sides of the hinged door frame 20, next to the hinged door 21. The door opening is not shown in the drawings.


When the lift basket 11 has a hinged door 21 that spans an entire width of the entrance, the covers 23 and 25, they would just cover the door 21. The outside cover 23 and inside cover 25 are attached to each other and are separated by the seam 32 resting on top of the hinged door frame 20. A bottom portion of the outside cover 23 includes a seam for holding a portion of a bungee cord 46.


A first side frame outside cover 26 is now unfolded and raised, as indicated by arrow 28, to cover an outside of the first side frame 14. At the same time, a first side frame inside cover 30 is used to cover the inside of the first side frame 14. The outside cover 26 and the inside cover 30 are attached to each other and are separated by a seam 32 resting on top of the first side frame 14.


As the liner 10 continues to be unfolded, a second side frame outside cover 34 is raised, as indicated by arrow 36, to cover an outside of the second side frame 16. At the same time, a second side frame inside cover 38 is used to cover the inside of the second side frame 14. The outside cover 34 and the inside cover 38 are attached to each other and are separated by the seam 32 resting on top of the second side frame 16.


Again, as the liner 10 continues to be unfolded, a front frame outside cover 40 is raised, as indicated by arrow 42, to cover an outside of the front frame 18. At the same time, a front frame inside cover 44 is used to cover the inside of the front frame 18. The outside cover 40 and the inside cover 44 are attached to each other and are separated by the seam 32 resting on top of the front frame 18.


The bottoms of the first side frame inside cover 30, the second side frame inside cover 38, the front frame inside cover 44, and the entrance door inside cover 25 are attached to the sides of the floor cover 24. The bottoms of the first side frame outside cover 26, the second side frame outside cover 34, the front frame outside cover 40, and the entrance outside cover 23 include a seam holding the bungee cord 46. The bungee cord 46 extends around the bottom of the plastic liner 10, as shown in the drawings, for holding the liner 10 in place on and around the lift basket 11.


In FIG. 2, a perspective view a portion of the liner 10 is shown cutaway to illustrate the liner covering an inside and outside of the first side frame 14, the second side frame 14, the front frame 18, and opposite sides of the hinged door frame 20.


Also shown in this drawing is a hinged door cover 48 positioned, as indicated by arrow 50, for covering a hinged door 21. The door cover 48 includes an outside cover 23 and an inside cover 25 for covering the inside and outside of the hinged door 21. A bottom portion of the outside cover 23 and the inside cover 25 includes strips of hook and loop fasteners 56 for securing the door cover 48 on the hinged door 21.


In FIG. 3A, a perspective view of a pair of human hands 58 are shown attaching an open end of the first outside cover 26 to an open end of the first inside cover 30, using strips of the hook and loop fasteners 56. The hook and loop fasteners are used to hold the covers 26 and 30 on the first side frame 14. The hook and loop fasteners are also used to hold the second outside cover 34 and the second inside cover 38 on the second side frame 16. Also, hook and loop fasteners can be used to hold the entrance door outside cover 23 and the entrance door inside cover 25 on the sides of the hinged door frame 20, next to the hinged door 21.


In FIG. 3B, a perspective view of the liner 10 is shown with the bungee cord 46 holding a bottom of the liner around a bottom of the lift basket 11. As mentioned above, the bungee cord 46 is used to hold the liner 10 in place on the lift basket 11. In this drawing, the second side frame 16 and the front frame 18 are shown in dashed lines and covered by the disposable plastic liner 10.


While the invention has been particularly shown, described and illustrated in detail with reference to the preferred embodiments and modifications thereof, it should be understood by those skilled in the art that equivalent changes in form and detail may be made without departing from the true spirit and scope of the invention as claimed except as precluded by the prior art.
