Abstract
Abstract A storage tray assembly comprising at least two separate trays of rectangular form together with at least two pairs of sidewall members which are of similar form and of L-shaped configuration, said sidewall members being arranged so that their lower portions can engage the upper part of one tray and their upper portions can engage the lower part of another tray so as to connect said trays together in a vertically spaced relationship, each tray having in its upper surface slot means which extend along each of two opposite lateral sides of the tray and at least partially along one of the other sides so as to be adapted to receive the lower portions of two of said L-shaped sidewall members, and having in its lower surface further slot means which extend along each of said two opposite lateral sides and at least partially along each of the other two sides so as to be adapted to receive the upper portions of two further L-shaped sidewall members so that a tray can be disposed relative to the pair of sidewall members beneath it in either of two alternative positions which are obtained by turning the tray through 180° about a vertical axis.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
218 words
A storage tray combination comprising at least two separate trays of generally rectangular form and at least two separately formed sidewall members of L-shaped configuration, lower portions of the sidewall members being engageable with an upper part of one of said trays while upper portions of the sidewall members are engageable with a lower part of another of said trays so as to connect said trays together in a vertically spaced relationship, each of said trays having an upper surface defining slot means extending along each of two opposite lateral sides of the tray and at least partially along one of the other sides of the tray for receiving the lower portions of two of said L-shaped sidewall members and each of said trays having a lower surface defining further slot means extending along each of said two opposite lateral sides of the tray and at least partially along each of the other two sides of the tray for receiving the upper portions of two of said L-shaped sidewall members, whereby said trays can be arranged together in said vertically spaced relationship in either of two alternative positions obtained respectively by turning said one tray horizontally through 180° relative to said other tray and in each of which positions the trays are arranged in a vertically aligned relationship.
Claim 2
Dependent Claim
218 words
A storage tray combination comprising at least two separate trays of generally rectangular form and at least two separately formed sidewall members of L-shaped configuration, lower portions of the sidewall members being engageable with an upper part of one of said trays while upper portions of the sidewall members are engageable with a lower part of another of said trays so as to connect said trays together in a vertically spaced relationship, each of said trays having an upper surface defining slot means extending along each of two opposite lateral sides of the tray and at least partially along one of the other sides of the tray for receiving the lower portions of two of said L-shaped sidewall members and each of said trays having a lower surface defining further slot means extending along each of said two opposite lateral sides of the tray and at least partially along each of the other two sides of the tray for receiving the upper portions of two of said L-shaped sidewall members, whereby said trays can be arranged together in said vertically spaced relationship in either of two alternative positions obtained respectively by turning said one tray horizontally through 180° relative to said other tray and in each of which positions the trays are arranged in a vertically aligned relationship.
Claim 3
Dependent Claim
49 words
A storage tray combination as claimed in claim 1 wherein each sidewall member is provided with a pair of spaced parallel guide formations which serve to indicate when said member is in a required position in the slot means of a tray with which said sidewall member is engaged.
Claim 4
Dependent Claim
42 words
A storage tray combination as claimed in claim 1 wherein each tray includes a wall portion with lateral parts defining recesses adapted to receive clips for connecting together two or more of said storage tray assemblies in a side by side relationship.
