Adjustable floor hole cover
An adjustable hole cover including an underside with one or more channels extending radially from the center of the cover to the outer edge. A row of apertures extends from the upper side into each of the channels. Retaining clips in each of the channels allow for adjustment of the cover to fit a wide range of hole sizes. The retaining clips include a base leg for sliding engagement with a channel and a second leg substantially orthogonal to the base leg. The base leg may be secured into one of the cover apertures to secure the retaining clip to the cover. Orientation of the retaining clip within the channel may be reversed to fit the cover to holes of a wide range of sizes. A reference scale on the underside of the cover allows for precise sizing to fit the hole diameter.
1. An adjustable hole cover comprising:
a cover plate including a center, a top surface having an outer edge, an underside, and an outer circumference, said top surface being substantially arcuate in shape and a juncture of said top surface and said outer edge defines a substantially right angle;
one or more channels, each said channel defined by a pair of parallel ribs, extending outward radially on said underside of said cover plate;
one or more bosses located in said one or more channels;
a removable L-shaped retaining clip positioned in each of said channels;
each said L-shaped retaining clip having a base leg which is substantially parallel to said underside of said cover plate and a second leg which extends substantially orthogonally from said base leg away from said underside of said cover plate; and
a fastener extending from said underside of said cover plate through each of said retaining clips and into a respective boss of said one or more bosses.
2. The adjustable hole cover of claim 1 , comprising a bore in each of said bosses.
3. The adjustable hole cover of claim 1 , comprising:
one or more rows of apertures in said cover plate; and
each of said rows of apertures in axial alignment with a corresponding channel of said cover plate.
4. The adjustable hole cover of claim 1 , comprising a slot in said base leg.
5. The adjustable hole cover of claim 1 , comprising a reference scale on the underside of the cover plate.
6. The adjustable hole cover of claim 5 , comprising a reference indicator on the underside of the cover plate.
7. The adjustable hole cover of claim 6 , comprising:
said reference scale is on a first of said parallel ribs; and
said reference indicator is on a second of said parallel ribs.
8. The adjustable hole cover of claim 7 , comprising said reference scale including numerals providing a guide to attachment of said retaining clips to fit a specific hole diameter.
9. The adjustable hole cover of claim 1 wherein said second leg is planar and includes an interior side facing the center of the hole cover and an exterior side which faces away from the center and towards the outer circumference of the top side;
an outside barb which is positioned on said exterior side of said second leg; and
said outside barb extending across the entire width of the second leg.
10. The adjustable hole cover of claim 9 further comprising a double barb consisting of said outside barb and further including an inside barb which is positioned on the interior side of the second leg.
11. The adjustable hole cover of claim 10 wherein said outside barb and inside barb are arcuate.
12. The adjustable hole cover of claim 11 further comprising a recess at one end of said second leg proximate to and between said inside barb and said outside barb.
