Abstract

Abstract The stand is for use in a motor vehicle. It has open and closed positions and when fully open provides a pair of adjoining compartments for receiving loaded grocery bags. The walls of the stand prevent the bags from tipping when they are subjected to the inertial forces resulting from starting, stopping or turning of the transporting vehicle. The two compartments are independently foldable and are open at both top and bottom. The walls are pivotally connected at each corner to allow independent folding of the compartments between open in use positions for receiving a loaded grocery bag and closed positions for more compact storage in the transporting vehicle. Friction locks are provided at each pivot joint for overridably locking the stand in its open and closed positions.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 266 words
A collapsible stand for maintaining loaded grocery bags, or the like, in an upright position even when subjected to sudden inertial forces such as those caused by the stopping, starting or turning of the vehicle in which the grocery bags are being transported, comprising: spaced apart, open-worked end and side walls defining an enclosure, wherein each end wall comprises an upper and lower end rail, and wherein each side wall comprises two upper side rails placed in end-to-end relation and two lower side rails placed in end-to-end relation; first pivotal means to pivotally interconnect the end and side walls; second pivotal means to pivotally interconnect the two upper side rails and the two lower side rails of each side wall; an open worked intermediate wall, extending between the spaced apart side walls to divide the enclosure into a pair of adjacent compartments having the intermediate wall as a common wall, and comprising an upper and lower intermediate rail, wherein each end of the intermediate wall is pivotally connected to its respective side wall by its respective side wall's second pivotal means; whereby the first and second pivotal means enable each adjacent compartment to be moved between an open position, for receiving a grocery bag which is prevented from tipping by bearing against the end, side and intermediate rails which surround it, and a collapsed position for more compact storage when not in use, wherein when both adjacent compartments are collapsed, the collapsed length of the stand is substantially equal to the length of the end wall plus one half of the length of one side wall.
Claim 2
Dependent Claim 266 words
A collapsible stand for maintaining loaded grocery bags, or the like, in an upright position even when subjected to sudden inertial forces such as those caused by the stopping, starting or turning of the vehicle in which the grocery bags are being transported, comprising: spaced apart, open-worked end and side walls defining an enclosure, wherein each end wall comprises an upper and lower end rail, and wherein each side wall comprises two upper side rails placed in end-to-end relation and two lower side rails placed in end-to-end relation; first pivotal means to pivotally interconnect the end and side walls; second pivotal means to pivotally interconnect the two upper side rails and the two lower side rails of each side wall; an open worked intermediate wall, extending between the spaced apart side walls to divide the enclosure into a pair of adjacent compartments having the intermediate wall as a common wall, and comprising an upper and lower intermediate rail, wherein each end of the intermediate wall is pivotally connected to its respective side wall by its respective side wall's second pivotal means; whereby the first and second pivotal means enable each adjacent compartment to be moved between an open position, for receiving a grocery bag which is prevented from tipping by bearing against the end, side and intermediate rails which surround it, and a collapsed position for more compact storage when not in use, wherein when both adjacent compartments are collapsed, the collapsed length of the stand is substantially equal to the length of the end wall plus one half of the length of one side wall.
Claim 3
Dependent Claim 59 words
A collapsible stand according to claim 1, wherein both ends of each end, side and intermediate rail have an opening, and wherein each first and second pivotal means comprises an axially elongated member pivotally cooperating with the openings, and wherein there are friction means positioned on each shaft to overridably lock the stand in its open or collapsed position.
Claim 4
Dependent Claim 68 words
A collapsible stand according to claim 2, wherein the end portions of the rails are thin, flat, and overlap at each first and second pivotal means, wherein the overlapping end portions of the rails at each first and second pivotal means are held in a tightly contacting relation by their respective pivotal means, and wherein the friction means comprises the tightly contacting, overlapping end portions of the rails.
Claim 5
Dependent Claim 27 words
A collapsible stand according to claim 3, wherein the lower end rails and the lower intermediate rail are coplanar and form a supporting base for the stand.
Claim 6
Dependent Claim 27 words
A collapsible stand according to claim 1, wherein the lower end rails and the lower intermediate rail are coplanar and form a supporting base for the stand.
