Platen cover for copying machines

Claim 2

In a document copying apparatus of the type having a platen on which documents to be copied are placed, the combination of: a cover for said platen; first hinge means for rotatably supporting said cover adjacent said platen to enable said cover selectively to be swung into and out of covering relationship with said platen and any document placed on said platen; said cover including a pair of generally rectangular opaque members sized so that when disposed side by side the inside surfaces of said members combine to form a covering surface at least as large as said platen; and second hinge means for connecting the adjoining sides of said members together, each of said member adjoining sides having an inside corner edge and an outside corner edge, said second hinge means comprising at least one hinging element operatively connected between said inside corner edges so that on swinging of said cover out of covering relationship with said platen said members fold inwardly one upon the other whereby to facilitate storing of said cover.

Claim 3

In a document copying apparatus of the type having a substantially rectangularly shaped platen with front and rear sides on which documents to be copied are placed, the combination of: a cover for said platen; first hinge means for rotatably supporting said cover adjacent said platen to enable said cover selectively to be swung into and out of covering relationship with said platen and any doCument placed on said platen; said cover including a pair of opaque members sized so that when disposed side by side said members combine to form a covering surface at least a as large as said platen; and second hinge means for joining said member sides together so that on swinging of said cover out of covering relationship with said platen said members fold inwardly one upon the other whereby to facilitate storing of said cover, said covering being substantially rectangular with front and rear edges corresponding to said platen front and rear sides, the dimension of said cover across said cover front and rear edges when unfolded being greater than the dimension across said platen front and rear sides such that said cover front edge projects beyond said platen front side; said first hinge means supporting said cover for rotation adjacent said platen rear side; the portion of said cover front edge projecting beyond said platen front side extending downwardly whereby on unfolding of said cover over said platen, said cover front edge overlays said platen front side.

Claim 4

In a document copying apparatus of the type having a substantially rectangularly shaped platen with front and rear sides on which documents to be copied are placed, the combination of: a cover for said platen; first hinge means for rotatably supporting said cover adjacent said platen to enable said cover selectively to be swung into and out of covering relationship with said platen and any doCument placed on said platen; said cover including a pair of opaque members sized so that when disposed side by side said members combine to form a covering surface at least a as large as said platen; and second hinge means for joining said member sides together so that on swinging of said cover out of covering relationship with said platen said members fold inwardly one upon the other whereby to facilitate storing of said cover, said covering being substantially rectangular with front and rear edges corresponding to said platen front and rear sides, the dimension of said cover across said cover front and rear edges when unfolded being greater than the dimension across said platen front and rear sides such that said cover front edge projects beyond said platen front side; said first hinge means supporting said cover for rotation adjacent said platen rear side; the portion of said cover front edge projecting beyond said platen front side extending downwardly whereby on unfolding of said cover over said platen, said cover front edge overlays said platen front side.

Claim 5

The apparatus according to claim 1 including means supporting said first hinge means for limited lifting movement above said platen whereby to enable said cover to unfold at a level above said platen.

Claim 6

In a document copying apparatus of the type having a platen on which documents to be copied are placed, the combination of: a cover for said platen; first hinge means for rotatably supporting said cover adjacent said platen to enable said cover selectively to be swung into and out of covering relationship with said platen and any document placed on said platen; said cover including a pair of opaque members sized so that when disposed side by side said members combine to form a covering surface at least as large as said platen; second hinge means for joining said member sides together so that on swinging of said cover out of covering relationship with said platen said members fold inwardly one upon the other whereby to facilitate storing of said cover; and means supporting said first hinge means for limited lifting movement above said platen whereby to enable said cover to unfold at a level above said platen, said first hinge supporting means including third hinge means mounted on said apparatus adjacent said platen; and an intermediate support element operatively connecting said first hinge means with said third hinge means whereby to enable said first hinge means with said cover to turn about said third hinge means to permit unfolding of said cover at a level above said platen.

Claim 7

In a document copying apparatus of the type having a platen on which documents to be copied are placed, the combination of: a cover for said platen; first hinge means for rotatably supporting said cover adjacent said platen to enable said cover selectively to be swung into and out of covering relationship with said platen and any document placed on said platen; said cover including a pair of opaque members sized so that when disposed side by side said members combine to form a covering surface at least as large as said platen; second hinge means for joining said member sides together so that on swinging of said cover out of covering relationship with said platen said members fold inwardly one upon the other whereby to facilitate storing of said cover; and means supporting said first hinge means for limited lifting movement above said platen whereby to enable said cover to unfold at a level above said platen, said first hinge supporting means including third hinge means mounted on said apparatus adjacent said platen; and an intermediate support element operatively connecting said first hinge means with said third hinge means whereby to enable said first hinge means with said cover to turn about said third hinge means to permit unfolding of said cover at a level above said platen.
