Abstract

A platform including an upper deck and a lower deck longer than the upper deck, both being constructed of a light-weight sturdy material. The edges of the upper deck extend downward and the edges of the lower deck extend upward. The decks are hinged together at the forward edge of the platform, which comes in contact with the roof. Male-female sleeves are attached to the inner parts of the sides and support pieces of both decks to provide support. The sleeves adjust so the platform can accommodate varying roof pitches. The bottom surface of the lower deck is covered in non-skid material to provide adhesion to the roof. The forward edge of the lower deck has extensions with holes so the platform can be secured to the roof with screws or nails.

  • FIG. 6 is a view of the topside of the lower deck of FIG. 1; and
  • FIG. 7 is a view of the underside of the upper deck of FIG. 1.
    • DESCRIPTION OF THE PREFERRED EMBODIMENT
  • Reference will now be made in detail to the present embodiment of the present invention, an example of which is illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout.
  • Referring to FIG. 1, reference numeral 5 generally indicates the HopBoard Roof Platform 5 according to an embodiment of the present invention (hereinafter “platform”). The platform 5 is secured to a roof 7. The platform 5 includes an upper deck 6 and a lower deck 8. The lower deck 8 is longer than the upper deck 6 in the direction of the slope of the roof 7. The upper deck 6 and lower deck 8 may be constructed of a light-weight yet sturdy material. The edges of the upper deck 6 extend downward and the edges of the lower deck 8 extend upward. Male sleeves 11 are attached to the lower deck 8, and female sleeves 13 are attached to the upper deck 6. The lower deck 8 is reinforced with a stiffener 26. The upper deck 6 is also reinforced with a stiffener, which is not shown. The bottom surface of the lower deck 8 is covered in a non-skid material 17 to provide greater friction and adhesion to the roof 7. Although not shown, the upper deck 6 may also be covered with the non-skid material 17.
  • Referring to FIGS. 2, 5, 6, and 7, the decks 6, 8 are joined by hinges 16 at the forward edge of the platform 5. The hinges 16 may be welded or similarly secured. A rear edge 9 of the lower deck 8 is opposite the forward edge 10 and is lower than the forward edge 10 of the lower deck 8 during operation.
  • The forward edge 10 of the lower deck 8 has extensions 23 at each corner thereof. The extensions 23 have holes 19 so the platform can be secured to the roof 7 with screws or nails, or any other securing apparatus. The male sleeves 11 are attached to inner parts of sides 12 of the lower deck 8. The female sleeves 13 are attached to inner parts of sides 14 of the upper deck 6. Support pieces 18 and 22 of the lower deck 8 and upper deck 6 respectively are attached to the male and female sleeves 11 and 13.
  • As shown in FIG. 3, the male sleeves 11 insert into the female sleeves 13 and are secured via cotter pin 15 (or bolt or other securing apparatus) to provide support. The male sleeves 11 each have sets of aligned holes 24 while the female sleeves 13 each have the single hole 25. Selecting a particular set of aligned holes 24 and securing via the cotter pin 15 with the holes 25 of each of the female sleeves 13 accommodates varying roof pitches.
  • As shown in FIGS. 4 and 5, in addition to allowing varying positions of the platform 5 for different roof pitches, the hinges 16 also allow the platform 5 to collapse for transport and/or storage. The male sleeves 11 fold down into the lower deck 8 and the female sleeves 13 fold up into the upper deck 6. A latch 28 secures the decks together during transport and/or storage. The forward edge 10 of the upper deck 6 may have an attached handle 21 for portability purposes.
  • Although an embodiment of the present invention has been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
