Total Claims: 12
Claim 1
Independent Claim
366 words
A foldable, stackable pallet comprising: (a) a support frame; (b) a plurality of support feet associated with said frame, each having a substantially rectangular cross section; (c) two inwardly foldable end walls; (d) first and second pairs of support columns, each pair associated with a respective one of said end walls and each column having a substantially rectangular cross section; (e) means for pivotally attaching each of said support columns to a respective one of said support feet; (f) a pair of removable side walls which are storable on said frame; each of said support feet and each of said columns having an upwardly extending protrusion formed on an upper end thereof and a cooperative recess formed on a lower end thereof and defined by side walls thereof; the recess formed on each of said support feet being adapted to selectively receive a protrusion formed on an upward end of a corresponding one of said columns of another pallet stacked therebelow in an extended condition and a protrusion formed on an upward end of a corresponding one of said support feet of another pallet stacked therebelow in a folded condition; the recess on each of said columns being registrable with a protrusion formed on an upper end of an associated one of said support feet to form a rigid, vertical connection therebetween; said pivotable attachment means comprising: a pair of depending plates externally disposed on opposite sides of each of said columns and extending downwardly therefrom to engage the corresponding sides of an associated support foot therebetween; an elongated slot in at least one plate of each pair of plates and extending longitudinally of the plate; a transverse pivot pin disposed on each of said support feet and extending therefrom through a respective one of said slots; a notch formed in at least one plate of each pair of plates; and a stop registrable with said notch when the recess on said support column is registered with the protrusion in said associated support foot; said stop, said notch, said pivot pin, said slot, said recess in said support column and said protrusion on said support foot in combination being operable to produce said rigid vertical connection.
Claim 2
Dependent Claim
366 words
A foldable, stackable pallet comprising: (a) a support frame; (b) a plurality of support feet associated with said frame, each having a substantially rectangular cross section; (c) two inwardly foldable end walls; (d) first and second pairs of support columns, each pair associated with a respective one of said end walls and each column having a substantially rectangular cross section; (e) means for pivotally attaching each of said support columns to a respective one of said support feet; (f) a pair of removable side walls which are storable on said frame; each of said support feet and each of said columns having an upwardly extending protrusion formed on an upper end thereof and a cooperative recess formed on a lower end thereof and defined by side walls thereof; the recess formed on each of said support feet being adapted to selectively receive a protrusion formed on an upward end of a corresponding one of said columns of another pallet stacked therebelow in an extended condition and a protrusion formed on an upward end of a corresponding one of said support feet of another pallet stacked therebelow in a folded condition; the recess on each of said columns being registrable with a protrusion formed on an upper end of an associated one of said support feet to form a rigid, vertical connection therebetween; said pivotable attachment means comprising: a pair of depending plates externally disposed on opposite sides of each of said columns and extending downwardly therefrom to engage the corresponding sides of an associated support foot therebetween; an elongated slot in at least one plate of each pair of plates and extending longitudinally of the plate; a transverse pivot pin disposed on each of said support feet and extending therefrom through a respective one of said slots; a notch formed in at least one plate of each pair of plates; and a stop registrable with said notch when the recess on said support column is registered with the protrusion in said associated support foot; said stop, said notch, said pivot pin, said slot, said recess in said support column and said protrusion on said support foot in combination being operable to produce said rigid vertical connection.
Claim 3
Dependent Claim
36 words
The pallet of claim 1 wherein said end walls lie flat without over-lapping one another when folded inwardly and said side walls are stored below said end walls, so that there is no interference with storing.
Claim 4
Dependent Claim
45 words
The pallet of claim 1 wherein channels are provided on said frame for positioning said side walls, said side walls having slidable top handles and said support columns having means for engaging said slidable handles so as to fasten said side walls to said columns.
Claim 5
Dependent Claim
36 words
The pallet of claim 1 wherein channels are provided in said frame for positioning said side walls and which cooperate with said side walls so as to be usable to force the contents into said container.
Claim 6
Dependent Claim
19 words
The pallet of claim 1 wherein the corners have straight, vertical sides for guiding or riding on a conveyor.
Claim 7
Dependent Claim
42 words
The pallet of claim 1 wherein the protrusions of said feet and columns are registrable with the bottom, hollow spaces of either a foot or a column so that the pallets are nestable upon one another whether in extended or folded condition.
Claim 8
Dependent Claim
19 words
The pallet of claim 6 wherein three folded pallets are stackable in the space of one fully extended pallet.
Claim 9
Dependent Claim
36 words

Claim 10
Dependent Claim
22 words
The pallet of claim 1 wherein said support feet have square corners at their bases to assist in use with a conveyor.
Claim 11
Dependent Claim
45 words
The pallet of claim 1 wherein said recess formed in each of said plurality of support feet has an opening which is flared to permit reception therein of an imprecisely positioned mating projection, said flared opening not extending beyond external boundaries of said support foot.
Claim 12
Dependent Claim
27 words
The pallet of claim 1 wherein the upwardly extending portions of said protrusions are chamfered to permit ease of insertion of said protrusion into a mating recess.
