Abstract

Abutment stops for adapting a gravity-fed shelving unit of a type commonly used in refrigerated displays to accommodate bottles having a contoured profile and a higher center of gravity than common cylindrical cans is disclosed. One such abutment stop includes a vertical wall having a slot for resting the device on a side wall of a channel of the shelving unit. The device is stabilized by a bifurcated mounting column extending back from the slot. The top of the abutment stop provides a support or rest for a portion of a frontmost bottle at a point higher than that at which the bottle would be supported by the shelving unit alone. A pair of such abutment stops, one on each side wall of the channel, may be provided at or near the front of the channel to support bottles within the channel. Optional variations include supports that extend into only channel, or into both adjacent channels, break away tabs at the bottom of the abutment stop to provide a height adjustment, and a top which may extend either in back of or in front of the vertical wall of the abutment stop. The abutment stop may also cooperate with a sliding stair-step-like support that rests on the same channel wall to provide another method of height adjustment. An alternate version of the device having a contoured front and back face, the front face contoured to fit against the front of the channel, and the back face contoured to support a bottle, is also described. This one-piece contoured version may be fit in the front of a single channel, and has a height greater than the front wall of the channel to provide support to a higher portion of a bottle than is possible with the front wall alone. Non-adjustable versions of the abutment stop may also be formed as an integral part of a shelf unit.

Claims

3. The improvement of claim 1 and wherein the mounting means further comprises adhesive means to secure the stop on a side wall of a channel.

4. An abutment stop for retrofitting a gravity-feed type shelf unit for containers, the shelf unit comprising one or more channels, each channel having at least a pair of opposed, longitudinally disposed side walls, each of which may be shared with an adjacent channel, a front wall, an opposed rear wall an a floor extending between the front and rear walls,

the abutment stop comprising:

(a) a vertical body portion adapted to engage one of the side walls of a channel, the body portion having a slot opening at and extending essentially vertically from the bottom of the vertical body portion and extending through the body portion, the slot being dimensioned to receive therein at least a portion of a side wall;

(b) a container engaging means positioned above the slot and in the path of travel in the channel of the forwardmost container to contact and support a portion of the container; and

(c) stabilization means on the back of the vertical body portion to prevent, when the slot is engaged with the side wall, rotational movement of the vertical body portion about a first axis parallel to the slot and rotational movement of the vertical body portion about a second axis perpendicular to the slot and the surface of the engaged side wall.

5. The abutment stop of claim 4, wherein the abutment stop further comprises reinforcement means disposed between the container engaging means and the stabilization means to provide additional rigidity.

6. The abutment stop of claim 5, wherein the container support means comprises an upper extension extending horizontally from the rear of the vertical body portion, the upper extension having an arcuate cut-out adapted to engage a portion of the external surface of a container.

7. The abutment stop of claim 6, wherein the upper extension has a pair of opposed, arcuate cut-outs therethrough, each cut-out adapted to engage a portion of the external surface of a container so as to support the forwardmost containers in adjacent channels at a select distance away from the front wall of the shelf unit.

8. The abutment stop of claim 6, wherein the stabilization means comprises a bifurcated mounting column enveloping the slot.

9. The abutment stop of claim 8, wherein the reinforcement means comprises a gusset.

10. An adjustable-height abutment stop for retrofitting a gravity-feed type shelf unit for containers, the shelf unit comprising one or more channels, each channel having at least a pair of longitudinally disposed side walls, each of which may be shared with an adjacent channel, and a front channel wall;

the adjustable-height abutment stop comprising;

(a) a front vertical portion adapted to engage one of the side walls of the channel, the front vertical portion defining a slot opening at and extending essentially vertically from the bottom of the front vertical portion;

(b) a container engaging means horizontally extending behind the front vertical portion and positioned above the slot to contact and support a portion of the forwardmost container in a channel;

(c) stabilization means on the back of the front vertical portion to prevent, when the slot is engaged with one of the side walls, rotational movement of the front vertical portion about an axis perpendicular to the slot and the surface of the engaged side wall; and

(d) calibration means disposed on a side of the stabilization means to provide a height indication of the container support means, whereby the container support means may be positioned at a selected height indicated by the calibration means by affixing the front vertical portion to the front channel wall.

11. The abutment stop of claim 10, wherein the abutment stop further comprises reinforcement means disposed between the container engaging means and the stabilization means to provide additional rigidity.

12. The abutment stop of claim 11, wherein the container engaging means comprises an upper extension extending horizontally from the rear of the front vertical portion, the upper extension having an arcuate cut-out therethrough which extends into the channel and which is to engage and support the forwardmost container in a channel.

13. The abutment stop of claim 12, wherein the container engaging means comprises an upper extension extending horizontally from the rear of the front vertical portion towards the rear wall of the shelf unit, the upper extension having opposed, parallel sides, a front and a pair of arcuate cut-outs interconnecting a side with the front, each cut-out adapted to support a container in adjacent channels.
