Adjustable compartment size storage unit

Claim 2

An adjustable compartment size storage unit comprising: top and bottom walls; side walls having a series Of parallel ''''V'''' shaped indentations formed into the inside surfaces thereof; means to secure said side walls to said top and bottom walls; and at least one horizontal partition positioned between said side walls and having one side edge supported by one of said side walls and having at least one integrally formed flexible tab extending outwardly from the opposite side edge thereof, said tab being spaced closely adjacent and extending substantially parallel to the lower surface of said partition, said tab being flexible in a downward direction and prevented from flexure in an upward direction by the lower surface of said partition, said tab being formed at its outer end at an angle of approximately 45* downwardly from the horizontal so as to engage one of said indentations in said side walls when said partition is moved in an upward direction causing said tab to flex downwardly until the outer end thereof engages an indentation in said side wall.

Claim 3

An adjustable compartment size storage unit comprising: top and bottom walls having a series of parallel indentations formed into the inside surfaces thereof; side walls having a series of parallel ''''V'''' shaped indentations formed into the inside surfaces thereof; means to secure said side walls to said top and bottom walls; at least one vertical partition having a series of parallel ''''V'''' shaped indentations formed into the outer surfaces thereof and a lower edge shaped to engage one of said indentations in said bottom wall and an upper edge having formed therein at least one vertically extending deflectable member for engagement with one of said indentations in said top wall whereby said vertical partition is introduced into said storage unit at an angle inclined from the vertical with said lower edge engaged with one of said indentations in said bottom wall and pivoted about said lower edge into a vertical position causing said vertical member on said upper edge to deflect until said vertical position is reached whereat said member engages said indentations in said top wall; at least one horizontal partition positioned between said side wall and said vertical partition having at least one integrally formed flexible tab extending outwardly from each side thereof, said tab being spaced closely adjacent and extending substantially parallel to the lower surface of said horizontal partition, said tab being flexible in a downward direction and prevented from flexure in an upward direction by the lower surface of said horizontal partition, said tab being formed at its outer end at an angle of approximately 45* downwardly from the horizontal so as to engage one of said indentations in said side wall and said vertical partition when said horizontal partition is moved in an upward direction causing said tab to flex downwardly until the outer end thereof engages said indentations in said side wall and said vertical partition.

Claim 4

An adjustable compartment size storage unit comprising: top and bottom walls having a series of parallel indentations formed into the inside surfaces thereof; side walls having a series of parallel ''''V'''' shaped indentations formed into the inside surfaces thereof; means to secure said side walls to said top and bottom walls; at least one vertical partition having a series of parallel ''''V'''' shaped indentations formed into the outer surfaces thereof and a lower edge shaped to engage one of said indentations in said bottom wall and an upper edge having formed therein at least one vertically extending deflectable member for engagement with one of said indentations in said top wall whereby said vertical partition is introduced into said storage unit at an angle inclined from the vertical with said lower edge engaged with one of said indentations in said bottom wall and pivoted about said lower edge into a vertical position causing said vertical member on said upper edge to deflect until said vertical position is reached whereat said member engages said indentations in said top wall; at least one horizontal partition positioned between said side wall and said vertical partition having at least one integrally formed flexible tab extending outwardly from each side thereof, said tab being spaced closely adjacent and extending substantially parallel to the lower surface of said horizontal partition, said tab being flexible in a downward direction and prevented from flexure in an upward direction by the lower surface of said horizontal partition, said tab being formed at its outer end at an angle of approximately 45* downwardly from the horizontal so as to engage one of said indentations in said side wall and said vertical partition when said horizontal partition is moved in an upward direction causing said tab to flex downwardly until the outer end thereof engages said indentations in said side wall and said vertical partition.

Claim 5

being flexible in a downward direction and prevented from flexure in an upward direction by the lower surface of said partition, and

Claim 6

being flexible in a downward direction and prevented from flexure in an upward direction by the lower surface of said partition, and

Claim 7

having an outer end projecting beyond and downwardly of said edge of said partition for cooperative locking engagement with said indentations in said side wall when moved in one direction with respect to said side wall, said outer end being operatively associated with said indentations so as to prevent release therefrom except by movement of said tab with respect to said side wall in said one direction, whereby said partition is held in locked engagement between said side walls against downward movement thereof and is releasable from its position between said side walls only by upward movement thereof with respect to said side walls.

Claim 8

having an outer end projecting beyond and downwardly of said edge of said partition for cooperative locking engagement with said indentations in said side wall when moved in one direction with respect to said side wall, said outer end being operatively associated with said indentations so as to prevent release therefrom except by movement of said tab with respect to said side wall in said one direction, whereby said partition is held in locked engagement between said side walls against downward movement thereof and is releasable from its position between said side walls only by upward movement thereof with respect to said side walls.

Claim 9

The storage unit of claim 2 wherein said horizontal partition further comprises vertical reinforcing ribs located on the underside of said partition and above each of said tabs.

Claim 10

The storage unit of claim 2 further comprising a back wall and wherein said top, bottom and side walls further comprise means to join together similar top, bottom and side walls of other storage units whereby a multiplicity of basic storage units may be formed.

Claim 11

An adjustable compartment size storage unit comprising: A. top and bottom walls; B. side walls having a series of horizontally spaced parallel indentations formed into the inside surfaces thereof; C. means to secure said side walls to said top and bottom walls; and D. at least one horizontal partition positioned between said side walls and including at least one relatively thin non-compressible flexible tab formed integrally with said partition and adjacent one side edge of said partition, said tab
