Stand-up roller apparatus
View Patent ↗Stand-up roller apparatus ( 20 ) for applying a uniform pressure to roofing membranes during installation on roofs according to the present invention comprises an elongated handle ( 21 ); a bracket ( 22 ) carried at one end of the handle; a roller assembly ( 23 ), rotatably affixed to the bracket and providing a sleeve, directly engageable with a roofing membrane being applied, wherein the dead weight of the apparatus is sufficient to join the applied roofing membrane to a mating surface on the roof without the application of additional downward force by the operator.
1. A roller apparatus comprising:
a handle;
a bracket attached to said handle; and
a roller assembly rotatably affixed to said bracket, where said roller assembly includes a roller and a replaceable rubber sleeve, where said sleeve is characterized by a Shore A durometer of less than about 60, and where the roller apparatus is characterized by a weight of about 20 to about 30 pounds.
2. The apparatus of claim 1 , where said roller comprises steel.
3. The apparatus of claim 1 , where said roller includes a cylindrical body, and where said rubber sleeve is positioned concentrically around said cylindrical body.
4. The apparatus of claim 1 , where said rubber sleeve contacts said roller around the entire circumference of said cylindrical body of said roller.
5. The apparatus of claim 1 , where said roller assembly includes an axle having inboard and outboard ends, where said inboard end is affixed to said bracket, and where said outboard end is adapted to receive a fastener assembly.
6. The apparatus of claim 5 , where said outboard end includes a threaded portion and said fastener assembly includes a nut.
7. The apparatus of claim 6 , where said fastener assembly includes a nut and a washer.
8. The apparatus of claim 5 , where said roller includes an aperture extending axially through the center of said cylindrical body.
9. The apparatus of claim 8 , where said roller is positioned concentrically around said axle and is axially secured into position by direct engagement of said fastener assembly, which is mated to said second end of said axle.
10. The apparatus of claim 9 , where said outboard end includes a threaded portion and said fastener assembly includes a nut.
11. The apparatus of claim 10 , where said fastener assembly includes a nut and a washer.
12. The apparatus of claim 1 , where said roller assembly further includes an axle sleeve, and where said sleeve includes a cylindrical body and an aperture extending axially through the center of said cylindrical body.
13. The apparatus of claim 12 , where said axle sleeve is positioned concentrically around said axle.
14. The apparatus of claim 1 , where said axle sleeve contacts said axle around the entire circumference of said axle, and where said roller contacts said axle sleeve around the entire circumference of said sleeve.
15. The apparatus of claim 1 , where said aperture extending axially through the center of said cylindrical body of said roller includes an inset at one axial end that provides an area to house said fastener assembly within the axial length of said roller.
16. The apparatus of claim 1 , where said handle includes a bent portion.
17. The apparatus of claim 1 , where the roller assembly consists essentially of a single roller, a replaceable rubber sleeve, an axle, optionally an axle sleeve, and a fastener assembly.
18. The apparatus of claim 1 , where the roller assembly consists of a single roller, a replaceable rubber sleeve, an axle, optionally an axle sleeve, and a fastener assembly.
