Abstract
Abstract A display device for mounting on the vertical front wall part of a nestable type shopping cart, the display device having a pair of display panels carrying intelligence mounted on opposite faces of said front wall part for vertical sliding travel between a lowered retracted position and an upper extended display position. Biasing means normally maintain the device in extended display position. When a shopping cart is nested into a second like shopping cart, the upwardly swingable rear wall part of the second cart is engaged by camming structure on at least one display panel to swing said rear wall part upwardly and thereby apply downwardly directed force against said display device to vertically slide it to retracted position.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
246 words
In a telescopingly nesting type shopping cart having a cart body comprising encircling wall structure defining the cart body and including a vertical front wall part having an upper edge and leading and trailing faces, and a rear wall part mounted for swinging movement inwardly and upwardly of the cart body, the body of said shopping cart being telescopingly nestably receivable in the cart body of a second like shopping cart through the rear of the latter with the body rear wall part of said second like shopping cart being swung inwardly and upwardly by engagement of the body front wall part of the first shopping cart therewith during nesting movement of the latter into the former, a display device comPrising a display panel having upper and lower margins and space therebetween for displaying intelligence, means for mounting said display panel on said cart body front wall part against one face thereof for vertical sliding travel thereon between a lower retracted position wherein the panel upper margin is located proximate the upper edge of said front wall part and an upper extended position wherein said panel upper margin is located distant from the upper edge of said front wall part, means for normally biasing said display panel into its extended position, and retracting means operable in opposition to said biasing means during the nesting movement of said cart into a like second cart for sliding said display panel from its extended position to its retracted position.
Claim 2
Dependent Claim
246 words
In a telescopingly nesting type shopping cart having a cart body comprising encircling wall structure defining the cart body and including a vertical front wall part having an upper edge and leading and trailing faces, and a rear wall part mounted for swinging movement inwardly and upwardly of the cart body, the body of said shopping cart being telescopingly nestably receivable in the cart body of a second like shopping cart through the rear of the latter with the body rear wall part of said second like shopping cart being swung inwardly and upwardly by engagement of the body front wall part of the first shopping cart therewith during nesting movement of the latter into the former, a display device comPrising a display panel having upper and lower margins and space therebetween for displaying intelligence, means for mounting said display panel on said cart body front wall part against one face thereof for vertical sliding travel thereon between a lower retracted position wherein the panel upper margin is located proximate the upper edge of said front wall part and an upper extended position wherein said panel upper margin is located distant from the upper edge of said front wall part, means for normally biasing said display panel into its extended position, and retracting means operable in opposition to said biasing means during the nesting movement of said cart into a like second cart for sliding said display panel from its extended position to its retracted position.
Claim 3
Dependent Claim
117 words
