Abstract

Abstract Disclosed is a holder for a roll of sheet material, having a pair of support levers rotatable only in one vertical plane pivotally attached in the forward portions of lateral walls projecting from the opposed ends of a rear wall and normally protruding inwardly toward each other. When said roll of sheet material is pushed upwardly in the holder from below said pair of support levers, said pair of support levers are brought into contact with the corners of the roll and are consequently rotated divergently. They presently ride over the corners of the roll and begin to slide over the lateral sides of the roll. When the forward tips of the support levers reach the open ends of the tubular core at the center of the roll, said pair of support levers return to their horizontal position, with the result that the roll will be set stably in position in the holder.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 278 words
A holder for a roll of sheet material having a cylindrical center hole of a predetermined diameter, the holder comprising a. a framework consisting of a rear wall and a pair of lateral side walls projecting from opposed ends of the rear wall, the walls of the framework enclosing a space for accommodating the roll; b. a pair of support levers for the roll, each of the support levers being pivotally mounted in a respective one of the side walls for free pivoting movement in a common plane extending perpendicularly to the side walls, each support lever having a tail end and a forward end, the forward ends projecting towards each other into said space, and the side walls being formed with respective grooves, each groove defining an upper shoulder engaging the forward end of an associated support lever when the support levers are pivoted upwardly in the common plane into a retracted position, said grooves having respective lower portions, said tail ends being pivoted to said side walls in said lower portions respectively, the length of the support levers being in excess of that of the grooves whereby only a portion of the support levers is received in the grooves in the retracted position and being shorter than the diameter of the center hole whereby the support levers are freely pivoted from the retracted position into a support position within the center hole when the center hole is in alignment with the support levers; and c. a cover for the roll, the lateral side walls having upper posterior portions and the cover having a rear edge pivotally attached to the posterior portions of the lateral side walls.
Claim 2
Dependent Claim 278 words
A holder for a roll of sheet material having a cylindrical center hole of a predetermined diameter, the holder comprising a. a framework consisting of a rear wall and a pair of lateral side walls projecting from opposed ends of the rear wall, the walls of the framework enclosing a space for accommodating the roll; b. a pair of support levers for the roll, each of the support levers being pivotally mounted in a respective one of the side walls for free pivoting movement in a common plane extending perpendicularly to the side walls, each support lever having a tail end and a forward end, the forward ends projecting towards each other into said space, and the side walls being formed with respective grooves, each groove defining an upper shoulder engaging the forward end of an associated support lever when the support levers are pivoted upwardly in the common plane into a retracted position, said grooves having respective lower portions, said tail ends being pivoted to said side walls in said lower portions respectively, the length of the support levers being in excess of that of the grooves whereby only a portion of the support levers is received in the grooves in the retracted position and being shorter than the diameter of the center hole whereby the support levers are freely pivoted from the retracted position into a support position within the center hole when the center hole is in alignment with the support levers; and c. a cover for the roll, the lateral side walls having upper posterior portions and the cover having a rear edge pivotally attached to the posterior portions of the lateral side walls.
Claim 3
Dependent Claim 34 words
The holder of a roll of sheet material as set forth in claim 1, further comprising a stop in the lower portion of the grooves for maintaining the support levers in the support position.
