SIDE-PIVOTED SELF-CONTAINED FASTENER-CONCEALING HINGE LEAF
Abstract
A hinge leaf of synthetic plastic material, such as polyethylene
or polypropylene, is provided with fastener holes to secure the
hinge leaf to the toilet seat or lid or other hinge member, and
also has a recess adjacent these holes. Formed integral with the
hinge leaf so that it cannot be lost or misplaced and is always at
hand is a fastener hole cover which swings downward to conceal the
fastener holes and has a tongue or lug which fits snugly into the
recess as a detent to hold the cover in place. The cover is hinged
along a side edge of the hinge leaf so as to swing thereover into
detent engagement with the undercut opposite side edge.

This is a division of our co-pending application Ser. No. 7,757,
filed Feb. 2, 1970, for Self-Contained Fastener-Concealing Hinge
Leaf, now U. S. Pat. No. 3,665,552 issued May 30, 1972.
Claims
We claim:
1. A self-Contained fastener-concealing hinge leaf, comprising
a hinge leaf body of flexible synthetic plastic material having an
elongated base portion with elongated opposite sides having
elongated straight and parallel opposite edge portions thereon with
a pair of fastener holes therethrough, said hinge leaf body having
at one end an enlarged portion integral with said base portion and
containing a hinge-pin-receiving bore,
an elongated fastener cover having elongated straight and parallel
opposite edge portions thereon and having on one of said edge
portions an integral elongated cover hinge portion forming a
pivotal connection with one of said parallel edge portions of said
body and swing-able therearound into concealing relationship with
said holes,
an elongated body detent portion on the side of said body opposite
the side thereof having said cover hinge portion,
and an elongated cover detent portion also on the side of said
cover opposite the side thereof having said cover hinge portion and
movable with said cover into and out of yieldingly-detained
engagement with said elongated body detent portion, wherein said
body detent portion comprises a recess disposed beneath the edge of
said base portion opposite said pivotal connection, and wherein
said cover detent portion has a projection on the side edge thereof
opposite said pivotal connection and adapted to be mated
detainingly with said recess.
Description
In the drawings,
FIG. 1 is a side elevation of one form of the invention, with the
cover in its closed position;
FIG. 2 is a top plan view of the hinge leaf of FIG. 1 with the
cover in its open position;
FIG. 3 is a cross-section taken along the line 3--3 in FIG. 2;
and
FIG. 4 is a perspective view looking downwardly and rearwardly from
above, of the hinge leaf shown in FIGS. 1 to 3 inclusive.
Referring to the drawings in detail, FIGS. 1, 2, 3 and 4 show a
self-contained fastener-concealing hinge construction, generally
designated 80, according to one form of the invention as consisting
of a hinge leaf body 12 having a base portion 14 and an
upwardly-inclined arm 16 at one end thereof containing a hinge pin
bore 18 for receiving the hinge pin (not shown) with which the
hinge leaf 80 is associated.
In the hinge leaf 80, the body 12 has straight parallel portions 82
and 84 along opposite side edges, the portion 84 having an undercut
portion or rabbet 86 which serves as a detent portion (FIG. 3). The
cover 88 is tapered at its opposite ends to conform to the contour
or outline of the body portion 12 but has a straight intermediate
inner edge portion or hinge portion 90 which is integrally-attached
to the straight portion 82 at its junction with the flat-bottom
surface 92. The cover 88 otherwise has an inclined inner side
portion 94 joining the hinge portion 90 to the top wall 96, which
at its opposite edge 98 has an inclined side portion or detent
portion 100 terminating in a straight inwardly-projecting detent
rib or bead 102. Accordingly, when the cover 88 is swung in a
counterclockwise direction as shown by the arrow 104 in FIG. 4, the
rib or bead 102 snaps into the undercut portion 86 while the top
wall 96 covers the fastener holes 106 and the fasteners (not shown)
therein.
The hinge leaf body 12 and the cover 88 integral therewith are
formed of a suitable flexible synthetic plastic material, such as
polyethylene or polypropylene plastic, so that the cover 88 can be
swung freely upward and downward into fastener-hole revealing and
fastener-hole concealing positions respectively. The flexing takes
place around the flexible pivotal connection 90, as shown by the
contrasting positions of FIGS. 1 and 4.
In the installation of the hinge leaf 80, the cover 88 is swung
upward and outward so that it is inclined away from the base 14
sufficiently to uncover the fastener holes 106. The workman then
lines up the hinge leaf 80 with the toilet seat, lid or other
article to which the hinge leaf is to be attached, drills the
necessary holes, if such drilling has not already been done,
inserts the screws or other fasteners in the holes 106 and drives
them in with a screw driver or power tool. When the fasteners are
properly seated, the operator swings the cover 28 forward and
downward so that the rib or bead 102 enters the recess 86 and
frictionally engages the side walls thereof with a detent action.
Thereafter, if such access is required, the operator pries up the
cover 88 by inserting a knife blade or screw driver between it and
the base 14, whereupon the screws or other fasteners are exposed
for tightening, removal or other desired action.
