Primary Examiner--Robert W. Michell Assistant E xaminer-Wenceslao J. Contreras Attorney-Fleit, Gipple & Jacobson [57] ABSTRACT A glass plate is adapted to be clamped against the front side of a rear wall. Strip membersembrace the edge of the glass plate and hold it in engagement against the rear wall and consist of spring legs, which are connected at least on two opposite'sides to the rear wall by a spring bight and are provided at their free forward ends with detent projections, which yield to rearward pressure applied by the glass plate until the latter snaps into position behind said projections. The detent projection consists of an end portion of the spring leg. This end portion is angled toward the interior of the passe partout and in resilient engagement with the beveled forward surface of the glass plate, which is beveled at its ends on both sides like a roof, so that the end portion of the spring leg holds the glass plate in position and the or forward end of the spring leg is substantially flush with the top or forward surface of the glass plate.
10 Claims, 3 Drawing Figures PATENTED 1 H973 3,727, 335- sum 20F 3 PATENTED APR 1 7 I975 SHEET 3 OF 3 QUICK-CLAMPING PASSE PARTOUT This invention relates to a quick-clamping passe partout, which comprises a rear wall or backing, a glass plate adapted to be clamped against the front side of the rear wall or backing, and strip members, which embrace the edge of the glass plate and hold it in engagement against the rear wall and consist of spring legs, which are connected to the rear wall at least on two opposite sides by a spring bight or web and are provided at their free forward ends with detent projections, which yield to rearward pressure applied by the glass plate until the latter snaps into position behind said projections. t
In a known passe partout of this kind, the spring legs are provided at their free forward ends with beveled detent noses, which protrude like wedges from the surface of the glass plate when the latter has been forced into position. Whereas that known passe partout is satisfactory, it has a clumsy appearance because the strip portions holding the glass plate protrude from the surface of the glass plate.
It is an object of the present invention to provide a quick-clamping passe partout which has a pleasing appearance and in which the frame that holds the glass plate is no longer prominent.
In a passe partout of the kind described first hereinbefore, that object is accomplished in that the detent projection consists of an end portion of the spring leg, which end portion is angled toward the interior of the passe partout and in resilient engagement with the beveled top surface of the glass plate, which is beveled at its ends on both sides like a roof, so that the end portion of the spring leg holds the glass plate in position, and that the top end of the spring leg is flush with the top surface of the glass plate. This design results in a picture frame assembly which has a large area and in which the frame that holds the glass plate does not define and limit the picture area. The use of this unpretentious, pleasing frame is particularly satisfactory in rooms with modern furniture.
In a development of the invention, the spring leg which forms the detent projection consists of transparent plastics material. The use of this material results in the pleasing impression of a glass plate which covers the picture behind it and is free of a holder. The glass plate appears to float before the picture which it protects.
In another desirable embodiment of the invention, the strip members have a recess, which receives an alu minum foil.
To facilitate the insertion of the glass plate, the same has slightly rounded corners and/or the strip members forming the spring legs are drawn outwardly at their lateral ends. These measures facilitate the forcing of theglass plate out of and into the plate-holding frame.
An embodiment of the invention will be explained more fully hereinafter with reference to the drawings, in which FIG. 1 is a sectional view,
F IG. 2 is a perspective elevational view showing the passe partout according to the invention with an enlarged portion, and
FIG. 3 is a top plan view showing another embodiment of the frame according to the invention with an enlarged portion.
The frame consists of the strip members 1, which are joined together. The rear wall 4 is adhered or welded to the horizontal web or spring bight 2 of the leg 3 of these The glass plate 10 is beveled also at its rearward edges 12 so that they can be forced into the frame without difficulty. As the glass plate 10 is forced against the frame, the top end portions 8 of the spring legs 7 slide on the beveled surfaces 12 until the top or forward end portions snap in against the beveled forward surfaces 9.
The strip members have a recess 13, which receives an aluminum foil 14, which is adhered or otherwise held in position.
FIG. 3 shows another embodiment of the passe partout according to the inventionand indicates by dotted lines the contour of the glass plate 10 inserted in the passe partout. The glass plate 10 has slightly rounded corners 18 so that the glass plate 10 can be forced more easily behind the top end portions 8 of the resilient legs 7. The forcing of the. glass plate 10 out of the holding means will also be facilitated by rounded corners of the glass plate 10 because pressure applied to the rear of the passe partout will cause the glass plate to spring out of one comer of the frame and the glass plate can then be seized with the f ngers and lifted ofi entirely.
The insertion and removal of the glass plate 10 can also be facilitated in that the free top end portions 8 of the resilient legs 7 are drawn outwardly at their lateral ends 16. In that case, the resistance presented at the corners of the passe partout to a movement of the glass plate 10 in response to pressure applied tothe rear wall will be reduced so that such pressure will cause the glass plate to spring out at one comer of the passe partout.
As is shown for the embodiment of FIG. 3, it will be desirable to provide the glass plate It) with rounded corners and to draw outwardly the' top end portions 8 of the resilient legs 7.
