ABSTRACT:
SUMMARY OF THE INVENTION
Broadly, the present invention comprises a stackable carrying rack comprising:
a support base provided with support legs extending downwardly from said base;
vertical support means mounted on said base and provided for supporting and storing a plurality of items placed in said rack;
wherein said support base has a configuration allowing to freely dispense items of smaller dimensions stored inside said rack downwardly though a central opening formed in said base without any obstructions or restrictions. Said support base has a generally square configuration formed by side support members, and wherein said central opening having a diamond-shape configuration formed by reinforcement members extending between each adjacent side support member and wherein said diamond-shaped configuration facilitates free dispensing of items through said central opening.
In another embodiment of the present invention, each of said reinforcement members forms a hypotenuse of a right triangle with respect to said adjacent side support members, and said vertical support means comprise vertical support posts mounted on each corner of said support base, wherein each of said posts is securely locked in a vertical position by means of linking cross-pieces provided to connect each pair of adjacent posts. Each of said linking cross-pieces comprises a sliding binder provided on each end with a square ring adapted to slide over said posts, and each of said linking cross-pieces comprises a locking binder provided with a disk-shaped locking element on each end adapted to be slidably locked within corresponding vertical slots formed near upper ends of said posts.
In yet another embodiment, said vertical support means comprise vertical support posts mounted on each corner of said support base, said posts being securely linked and locked in vertical position by means of side walls mounted between each pair of adjacent posts, wherein said side walls are provided with a locking means adapted to securely hold said walls in vertical position. Said locking means comprises an upper locking means located near upper corners of said side walls and a lower locking means located on lower portions of said side walls. Said upper locking means comprise locking elements having a disk-shaped configuration adapted to be slidably locked within corresponding vertical slots formed near upper ends of said posts, and said lower locking means comprises a retaining bracket adapted to be securely engaged with the corresponding side support member of said support base. Said lower locking means comprise a pair of pins extending downwardly from a lower edge of said side wall, said pins are adapted to be inserted into corresponding openings formed on the side support member of said support base.
In still another embodiment of the present invention, at least one of said side walls has a two-section configuration divided into an upper section and a lower section. Said lower section is slidably mounted on the adjacent posts by means of square rings located on each corner of said lower section and wherein said upper section is mounted on said adjacent posts by means of locking elements located on upper corners of said upper section, said locking elements having a disk-shaped configuration and are slidably locked within corresponding vertical slots formed near upper ends of said posts. Said upper section is securely retained on said lower section by means of at least one retaining bracket adapted to engage an upper edge of said lower section, and said side walls have a screen-shaped configuration. Said support base is further provided with a bottom plate placed over said support base, said bottom plate is adapted to be slidably removed from said base to facilitate free dispensing of items stored in said rack through the central opening formed in said base.
