Modular shelf unit enclosure or greenhouse
A modular greenhouse enclosure is formed by mounting on a conventional shelf storage unit having spaced shelves supported on upright posts a rigid frame on which an impervious transparent cover is supported. The cover overlies and extends past the side edges of the shelves to define the enclosure. A vertical gap opening in the cover gives access to the shelves within the enclosure, and this opening can selectively be closed. The frame can be modular, formed from a plurality of posts and connectors, generally with three posts secured to each connector held angled relative to one another. Some of these frame posts can be connected to the shelf unit to hold the frame overlying the shelf unit. Several storage units can be positioned proximate one another for increasing shelf capacity, with a single frame and cover overlying all units.
1. A modular greenhouse or enclosure, comprising the combination of
a free standing storage unit having several shelf components and a plurality of posts, each shelf components having angularly arranged peripheral side edges and means proximate the side edges to provide connections to said posts operable to hold said shelf components in separated generally parallel overlying association with each other and with the side edges in vertical alignment;
a separate rigid modular frame having spaced end projections and a medial span extended between the end projections, and means to separably connect the end projections relative to the storage unit operable to hold said medial span in vertically separated overlying association with the uppermost shelf component;
a cover in the form of a generally impervious and transparent plastic sheet having a medial portion adapted to overlie and be supported on the medial frame span and having a perimeter portion sized larger than the shelf components side edges and depending downwardly from the medial portion adapted to extend past the side edges of the shelf components and posts and enclose the storage unit, and said cover perimeter portion including a first section thereof lying closely adjacent certain shelf components side edges and having a second section thereof enclosing the remaining shelf components side edges; and
the cover perimeter portion second section having a vertically elongated gap opening therein operable to provide access to said shelves within the enclosure, and a panel suited to cooperate with the cover perimeter portion to close the gap opening and enclosure and suited in a rolled up position to expose the gap opening and provide said shelf access.
2. A modular greenhouse or enclosure according to claim 1 , further comprising the use therein of a second free standing storage unit similar to the first free standing storage unit, the different free standing storage units being located proximate but spaced from one another to define an aisle therebetween, said separate rigid frame overlying and having end connections to each storage unit, and said cover second section having said gap opening aligned with the aisle to provide said shelf access via the aisle between said storage units.
3. A modular greenhouse or enclosure according to claim 1 , further comprising the frame including of a plurality of posts having ends suited to form said frame end connections, a plurality of connectors each having three end projections to connect with three posts and hold them angled relative to one another in the rigid frame, each connector being comprised as two separable half pieces each having engaging edges and means connecting the respective half piece edges together to form the whole connector, one half piece of each connector being shaped to provide one half of two of the connector end projections and the other half piece of each connector being shaped to provide the other half of the two connector end projections and a complete third end projection.
4. A modular greenhouse or enclosure according to claim 3 , further comprising the use therein of a second free standing storage unit similar to the first free standing storage unit, the different free standing storage units being located proximate but spaced from one another to define an aisle therebetween, said separate rigid frame overlying and having end connections to each storage unit, and said cover second section having said gap opening aligned with the aisle to provide said shelf access via the aisle between said storage units.
