Claims
What is claimed is:
1. A picture support comprising a transparent front panel, an
opaque coating on the rear face of said panel along the peripheral
edges thereof leaving a viewing area through said front panel
centrally thereof, a mounting panel bonded to said opaque coating,
said mounting panel having a central open area at least as large as
the viewing area in the transparent panel, a rear panel for
supporting a picture to be viewed through said viewing area, a
plurality of connecting lugs integrally secured to said mounting
panel and extending rearwardly therefrom, and a plurality of bores
formed in said rear panel for tightly engaging over said lugs to
secure said rear panel to said mounting panel, said bores and said
lugs being positioned rearwardly of said opaque coating to be
completely invisible from the front of said picture support.
2. A device as claimed in claim 1 wherein said opaque coating
consist of a relatively thick peelable coating partially removeable
to produce the viewing area for said front panel.
3. A picture support as claimed in claim 1 wherein each of said
front and rear panels comprise flat continuous bodies each of
substantially constant thickness.
4. A picture support as claimed in claim 3 wherein each of said
front and rear panels is of rectangular shape and substantially
equal size.
5. A picture support as claimed in claim 1 wherein said connecting
lugs are short cylinders and said bores in the rear panel have
diameters such as to frictionally fit over said lugs.
6. A picture support as claimed in claim 1 wherein each of said
connecting lugs has an axial threaded bore, and threaded means
engaging in said threaded bores for releasably securing said back
panel onto said lugs.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to picture supports which give the
appearance of being frameless and in which the connectors are
completely hidden.
2. Summary of the Invention
A picture support which includes a transparent front panel having
an opaque coating on its rear face with a transparent exposed
central portion for viewing the picture. A central panel is
provided with a picture receiving opening and is bonded to the
opaque coating on the transparent front panel. The central panel
has a plurality of connector lugs extending rearwardly therefrom.
The back panel has a plurality of holes to receive the connector
lugs to secure the transparent front panel to the back panel. The
back panel is also provided with conventional picture hanging clips
for receiving a hanging wire.
The primary object of the invention is to provide a picture support
which gives the appearance of being completely frameless and
completely without connectors between the several panels.
Other objects and advantages will become apparent in the following
specification when considered in the light of the attached
drawings.

FIG. 5 is a fragmentary exploded perspective of a modified form of
the invention
DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings in detail wherein like reference
characters indicate like parts throughout the several figures the
reference numeral 10 indicates generally a picture support
constructed in accordance with the invention.
The picture support 10 includes a generally rectangular transparent
front panel 11 formed of glass, plastic or any other rigid
transparent material. The front panel 11 has a peelable opaque
coating 12 adhered thereto on the inner face thereof. A central
panel 13 of the peelable coating 12 is peripherally outlined by a
knife cut 14 following which the central panel 13 is removed to
provide a display area 15.
A generally rectangular mounting panel 16 has the same outer
dimensions as the front panel 11 and has a generally rectangular
opening 17 formed centerly. The opening 17 is at least as large as
the display area 15 centerly of the opaque coating 12 and may be
substantially larger as explained below.
The mounting panel 16 has a plurality of connector lugs 18 formed
thereon and extending outwardly rearwardly therefrom. The mounting
panel 16 is bonded to the peelable opaque coating 12 by any
suitable bonding material or method.
A generally rectangular rear panel 19 has an outer dimension equal
to the front panel 11 and is provided with a plurality of connector
bores 20 throughwhich the connector lugs 18 are pressed to secure
the front panel 11 to the rear panel 19. A pair of clips 21 are
secured to the rear face of the rear panel 19 to receive a picture
wire 22 fastened thereto, however, other hanging devices and/or
supports may be used.
A picture 23 of generally rectangular configuration is positioned
in the viewing area 15 in the opening 17 of the mounting panel 16
and the back panel 19 is engaged thereagainst with the lugs 18
extending through the bore 20 to provide the complete picture as
viewed in FIG. 1.
The peelable opaque coating 12-13 is cut along a line 14 and the
area 13 is peeled off to provide a mask for the picture 23 and any
size or shape of viewing opening 15 may be provided as desired.
The connector lugs 18 cooperate with the bores 20 to maintain
constant pressure therein and resist disengagement therefrom except
by force.
While the coating 12 has been described as a peelable opaque
coating it should be understood that non-peelable opaque coatings
may also be used in which case the viewing area 15 is not coated
during the coating step.
The mounting panel 16 and the rear panel 19 may be formed of any
suitable material such as plastic, wood, metal, or any other
material found suitable for the purpose.
Applicants picture support produces a unique appearance in that
there is no visible frame, or even connectors when viewed from the
front. While the support and picture have been described as
generally rectangular they may have any desired outline.
In FIG. 5 a modified form of the invention is illustrated wherein
the panel 16' is provided with a plurality of lugs 18' with each
lug 18' having an axial threaded bore B. The back panel 19' has
bores 20' which freely admit the lugs 18'. A cap screw S is
threaded into the bore B and with a washer W secures the panel 19'
to the panel 16'.
Having thus described the preferred embodiments of the invention it
should be understood that numerous structural modifications and
adaptations may be resorted to without departing from the spirit of
the invention.
