The railing support comprises an angle body comprising a first elongate member and a second elongate members that is perpendicular to the first elongate member, and a first bracket extending inward from the first elongate member and a second bracket extending inward from the second elongate member, each bracket having a coaming-receiving portion that is sized and shaped to directly engage the inner surface, upper surface and outer surface of the hatch coaming, and a flashing covering portion that is sized and shaped to receive the flashing, the bracket engages the coaming such that the angle body is supported laterally adjacent to the flashing of the coaxing. There are one or more post supports connected to and extending outward from angle body.
- According to another aspect, the first and second elongate members may be connected at a corner of the angle body. There may be a post support connected to and extends outward from the corner of the angle body.
- According to another aspect, the first and second brackets may further comprise an underlying portion that extends through the opening of the roof and engages an under surface of the roof. The underlying portion may be pin connected to the under surface of the roof.
- According to another aspect, the brackets may be pin connected to the coaming.
- According to another aspect, one or more flashing inserts may be inserted between the flashing and the coaming. The one or more flashing inserts may underlie the bracket.
- According to another aspect, the flashing engaging portion is sized and shaped to directly engage the flashing.
- According to another aspect, there is provided a method of installing a railing around a roof hatch, the roof hatch comprising a hatch cover supported by a hatch coaming mounted to the roof, the hatch coaming comprising an inner surface surrounding an opening in the roof, an upper surface, an outer surface and flashing extending out from an outer surface of the hatch body and spaced downward from the upper surface, the railing comprising support posts and cross members supported by the support posts, the method comprising the steps of: providing railing supports as described above; installing the railing supports at each corner of the roof hatch by placing the first and second bracket over the hatch coaming such that the angle body is supported laterally adjacent to the flashing of the coaming; and installing the support posts and the cross members around the roof hatch by installing the support posts in the post supports.
- These and other features will become more apparent from the following description in which reference is made to the appended drawings, the drawings are for the purpose of illustration only and are not intended to be in any way limiting, wherein:
-
FIG. 1 is a perspective view of a prior art hatch railing system. -
FIG. 2 is a side elevation view of a prior art corner support. -
FIG. 3 is a perspective view of a railing support. -
FIG. 4 is a top plan view of a railing support installed on a hatch coaming. -
FIGS. 5 and 6 are side elevation views of the railing support installed on a hatch coaming. -
FIG. 7 is a side elevation view of an alternative railing support. - A
support 10 for a railing of a roof hatch is shown inFIG. 3 through 7 , and is used to supportposts 112 around hatch coaming 105.Hatch coaming 105 is mounted toroof 106 and has aninner surface 116 surrounding anopening 118 inroof 106, anupper surface 120, anouter surface 122 and flashing 110 that extends out fromouter surface 122 and is spaced downward fromupper surface 120.Hatch coaming 105 has a cross-section defined by these features, and support 10, as will be described below, has a similar shape that engages hatch coaming 105. - Referring to
