Abstract
Abstract A shelf assembly including a panel forming a shelf with a back wall, bottom wall and side walls and having an elongated front shelf member and an end cap holding the shelf front member to each side wall of the shelf. The end cap has a base wall with perpendicular integrally formed rear, side and front flanges and the base wall has at the front thereof projections for securing thereto one end of the shelf front member. The end cap has a latching assembly secured to the rear flange and projecting rearwardly and receivable in an aperture in the panel side wall and includes two support legs each having a width slightly less than the distance between opposite edges of the side wall aperture. A spring member is located between the legs and attached to both support legs at one end away from the rear flange and the distal end of the spring member is free. The spring member has an inclined ramp portion extending from the attached end toward the rear flange and extends outside the diameter of the aperture in the panel. The spring member also has a panel engaging portion depending from the ramp portion in a direction of the leg at an inclined angle with the rear surface of the panel side wall of between 95 and 160 degrees. With the spring member being depressed and inserted into the aperture the rear flange abuts one side of the panel and the panel engaging portion of the spring member is biased against only the rear surface of the panel side wall to secure the end cap to the panel and the end cap is removable therefrom by depressing the spring member and withdrawing the end cap from the aperture.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
385 words
A shelf front assembly comprising: a panel forming a shelf with a bottom wall and side walls, each said side wall having a front face with a rear surface and a front surface and having therethrough a rectangular shaped aperture having long and short sides with the long sides of the aperture being vertically oriented and the short sides horizontally oriented; an elongated shelf front member, and an end cap removably secured to the panel, said end cap having; a base wall with integrally formed rear, side and front flanges depending in the same direction therefrom, said base wall having at the front thereof means securing one end of the shelf front member, a latch assembly attached to the rear flange and projecting rearwardly therefrom and received in the panel side wall aperture, said latch assembly including; two support legs attached at one end to the rear flange and having a width less than the length of the rear flange and slightly less than the distance between opposite edges of the short sides of the panel side wall aperture; a spring member located between the support legs and attached to both support legs at one end thereof away from the rear flange and the distal end of the spring member is free, the spring member having an inclined ramp portion extending from the attached end toward the rear flange and extending outside the width of the aperture in the panel and a panel engaging portion depending from the ramp portion in the direction of the leg at an included angle with a plane representing the rear surface of the panel side wall when the end cap is installed in the panel aperture of between 95 and 160 degrees when the spring member is in its free state, said panel engaging portion being biased against only the rear surface of the panel side wall; whereby upon depressing the spring member and inserting the latch assembly in the panel side wall aperture the rear flange abuts the front of the panel side wall at both long sides of said aperture and the panel engaging portion of the spring member is biased against the rear surface of the side wall adjacent the long side of the panel side wall aperture to secure the end cap to the panel.
Claim 2
Dependent Claim
385 words
A shelf front assembly comprising: a panel forming a shelf with a bottom wall and side walls, each said side wall having a front face with a rear surface and a front surface and having therethrough a rectangular shaped aperture having long and short sides with the long sides of the aperture being vertically oriented and the short sides horizontally oriented; an elongated shelf front member, and an end cap removably secured to the panel, said end cap having; a base wall with integrally formed rear, side and front flanges depending in the same direction therefrom, said base wall having at the front thereof means securing one end of the shelf front member, a latch assembly attached to the rear flange and projecting rearwardly therefrom and received in the panel side wall aperture, said latch assembly including; two support legs attached at one end to the rear flange and having a width less than the length of the rear flange and slightly less than the distance between opposite edges of the short sides of the panel side wall aperture; a spring member located between the support legs and attached to both support legs at one end thereof away from the rear flange and the distal end of the spring member is free, the spring member having an inclined ramp portion extending from the attached end toward the rear flange and extending outside the width of the aperture in the panel and a panel engaging portion depending from the ramp portion in the direction of the leg at an included angle with a plane representing the rear surface of the panel side wall when the end cap is installed in the panel aperture of between 95 and 160 degrees when the spring member is in its free state, said panel engaging portion being biased against only the rear surface of the panel side wall; whereby upon depressing the spring member and inserting the latch assembly in the panel side wall aperture the rear flange abuts the front of the panel side wall at both long sides of said aperture and the panel engaging portion of the spring member is biased against the rear surface of the side wall adjacent the long side of the panel side wall aperture to secure the end cap to the panel.
Claim 3
Dependent Claim
22 words
The shelf front assembly of claim 1 wherein all elements and members of the end cap are integrally molded from plastic material.
Claim 4
Dependent Claim
