Abstract

A seal system includes one or more corner seals and a sill seal attachable to the corner seal(s). The sill seal includes a horizontal portion, an outer flange depending from the horizontal portion, an oblique portion extending obliquely from the horizontal portion, and an inner flange extending upwardly from the horizontal portion. A wiper extends upwardly from the inner flange. The inner flange and oblique portion cooperate to form a trough. One or more weep holes are formed in the inner flange to allow for communication of water from the trough to the other side of the inner flange.

First claim

The invention claimed is:

1. A seal system for a slide out room of a recreational vehicle, comprising:
a sill seal comprising:
a horizontal portion having a first edge and a second edge;
a first vertical flange extending downwardly from said horizontal portion proximate said first edge of said horizontal portion;
an oblique portion extending upwardly from said horizontal portion proximate said second edge of said horizontal portion at an obtuse angle thereto;
a second vertical flange extending from said horizontal portion proximate said second edge of said horizontal portion, said second vertical flange comprising a plurality of weep holes proximate a junction of said second vertical flange with said horizontal portion, and
a wiper attached to and extending upwardly from said second vertical flange of said sill seal,
said plurality of weep holes configured to allow communication of water wiped by the wiper through said second vertical flange;
said second vertical flange and said oblique portion cooperating to define a trough therebetween; and

a corner seal comprising:
a horizontal portion having a first side, a second side, a first edge, and a second edge;
an oblique portion having a first end and a second end, said oblique portion extending upwardly and outwardly from said second edge of said horizontal portion;
a vertical portion extending upwardly from said second end of said horizontal portion and connected to said second end of said oblique portion; and
a vertical flange extending downwardly from said first end of said horizontal portion and outwardly from said vertical portion;

wherein at least a portion of said horizontal portion of said sill seal overlies at least a portion of said horizontal portion of said corner seal; and
wherein at least a portion of said oblique portion of said sill seal overlies at least a portion of said oblique portion of said corner seal.

2. The seal system of claim 1 ,
said oblique portion of said sill seal further comprising a free edge, said free edge of said sill seal comprising an elongated channel, and
said oblique portion of said corner sill further comprising a free edge, said free edge of said corner seal comprising an elongated bead,
wherein said elongated bead is received within said elongated channel.

3. The seal system of claim 1 , said corner seal further comprising a stop member attached to said horizontal portion and spaced from said vertical portion.

4. The seal system of claim 1 further comprising an adhesive disposed between one of said horizontal portion and said oblique portion of said sill seal and a corresponding one of said horizontal portion and said oblique portion of said corner seal.

5. The seal system of claim 1 , said sill seal further comprising a bulb seal attached to said first vertical flange.

6. The seal system of claim 1 , said sill seal further comprising:
a tab-receiving channel extending outwardly from said first vertical flange; and
a first latch member extending outwardly from said first vertical flange.

7. The seal system of claim 6 further comprising a bulb seal removably attached to said first vertical flange, said bulb seal comprising a tab selectively received within said tab-receiving channel, and a second latch member selectively engaged with said first latch member.

8. A sill seal for a slide out room of a recreational vehicle, comprising:
a horizontal portion having a first edge and a second edge;
a first vertical flange extending downwardly from said horizontal portion proximate said first edge of said horizontal portion;
an oblique portion extending upwardly from said horizontal portion proximate said second edge of said horizontal portion at an obtuse angle thereto;
a second vertical flange extending from said horizontal portion proximate said second edge of said horizontal portion, said second vertical flange comprising a plurality of weep holes proximate a junction of said second vertical flange with said horizontal portion; and
a wiper attached to and extending upwardly from said second vertical flange of said sill seal,
said plurality of weep holes configured to allow communication of water wiped by the wiper through said second vertical flange;

said second vertical flange and said oblique portion cooperating to define a trough there between.

9. The sill seal of claim 8 , said oblique portion further comprising a free edge, said free edge of said sill seal comprising an elongated channel.

10. The sill seal of claim 8 further comprising a bulb seal attached to said first vertical flange.

11. The sill seal of claim 8 further comprising:
a tab-receiving channel extending outwardly from said first vertical flange; and
a first latch member extending outwardly from said first vertical flange.

12. The sill seal of claim 11 further comprising a bulb seal removably attached to said first vertical flange, said bulb seal comprising a tab selectively received within said tab-receiving channel, and a second latch member selectively engaged with said first latch member.

13. The sill seal of claim 11 further comprising a bulb seal attachable to said first vertical flange, said bulb seal comprising a tab receivable within said tab-receiving channel, and a second latch member engagable with said first latch member.

14. The sill seal of claim 8 wherein said horizontal portion is imperforate.
