Abstract
Abstract A two-sided storage system or bin comprising a plurality of flat, rigid shelves arranged in a zig-zag vertical arrangement in such a manner that alternate shelves of the system or bin are located in alternate oblique planes extending transversely of the shelves at an acute angle preferably not exceeding 15 degrees, in alternating opposite directions from horizontal. The system or bin provides access openings to compartments converging transversely from said access openings on each longitudinal side of the system or bin for a pair of operators working simultaneously on opposite sides of the system or bin and prevents each operator from interfering with the work of the other operator. The oblique support planes for the shelves improves the vision area of each operator over what would exist if the shelves extended horizontally. Furthermore, the amount of space occupied by the two operators working simultaneously along the opposite longitudinal sides of the system or bin is only slightly more than what a single operator occupies.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
346 words
A two-sided storage system or bin comprising shelf support means and a plurality of flat, rigid shelves supported thereby in a zig-zag vertical arrangement relative to said shelf support means in such a manner that alternate of said shelves are located in alternate oblique planes extending transversely of said shelves at an acute angle in alternating opposite directions from the horizontal, said storage system or bin having a first longitudinal side and a second longitudinal side, each of said flat, rigid shelves having a first longitudinal side edge extending along said first longitudinal side and a second longitudinal side edge extending along said second longitudinal side, the first longitudinal side edge of each alternate one of said shelves substantially abutting the first longitudinal side edge of one of said shelves vertically adjacent thereto to one side thereof to form a closed transverse side of a compartment along said first longitudinal side of said system or bin and vertically spaced from the first longitudinal side edge of another one of said vertically adjacent shelves to the other vertical side thereof to form a first access opening along said first longitudinal side to a compartment that converges transversely inward from said access opening, the second longitudinal side edge of said one alternate shelf substantially abutting the second longitudinal side edge of said other one of said vertically adjacent shelves to said other vertical side thereof to form a closed transverse side of another compartment along said second longitudinal side of said system or bin and vertically spaced from the second longitudinal side edge of said one of said vertically adjacent shelves to said one vertical side of said alternate one of said shelves to form a second access opening to a compartment, said second access opening extending along said second longitudinal edge of said system or bin, each vertically adjacent upper surface accessible along substantially the entire length of said shelf, adjacent of said shelves being accessible from alternate sides of said system or bin from the top shelf to the bottom shelf of said system or bin.
Claim 2
Dependent Claim
346 words
A two-sided storage system or bin comprising shelf support means and a plurality of flat, rigid shelves supported thereby in a zig-zag vertical arrangement relative to said shelf support means in such a manner that alternate of said shelves are located in alternate oblique planes extending transversely of said shelves at an acute angle in alternating opposite directions from the horizontal, said storage system or bin having a first longitudinal side and a second longitudinal side, each of said flat, rigid shelves having a first longitudinal side edge extending along said first longitudinal side and a second longitudinal side edge extending along said second longitudinal side, the first longitudinal side edge of each alternate one of said shelves substantially abutting the first longitudinal side edge of one of said shelves vertically adjacent thereto to one side thereof to form a closed transverse side of a compartment along said first longitudinal side of said system or bin and vertically spaced from the first longitudinal side edge of another one of said vertically adjacent shelves to the other vertical side thereof to form a first access opening along said first longitudinal side to a compartment that converges transversely inward from said access opening, the second longitudinal side edge of said one alternate shelf substantially abutting the second longitudinal side edge of said other one of said vertically adjacent shelves to said other vertical side thereof to form a closed transverse side of another compartment along said second longitudinal side of said system or bin and vertically spaced from the second longitudinal side edge of said one of said vertically adjacent shelves to said one vertical side of said alternate one of said shelves to form a second access opening to a compartment, said second access opening extending along said second longitudinal edge of said system or bin, each vertically adjacent upper surface accessible along substantially the entire length of said shelf, adjacent of said shelves being accessible from alternate sides of said system or bin from the top shelf to the bottom shelf of said system or bin.
Claim 3
Dependent Claim
62 words
A system as in claim 1, wherein each of said shelves has a first longitudinal end portion and a second longitudinal end portion and said shelf support means comprises a first pair of vertically extending attachment posts rigidly connected to said first longitudinal end portions and a second pair of vertically extending attachment posts rigidly connected to said second longitudinal end portions.
Claim 4
Dependent Claim
74 words
A system or bin as in claim 1, wherein one of said longitudinal side portions of each of said shelves is lower than the other longitudinal side portion of said shelf, further including raised abutment means constructed and arranged to extend along the lower longitudinal side portion of each of said shelves at the access opening to each of said compartments to prevent slippage of objects supported on the upper surfaces of said shelves.
Claim 5
Dependent Claim
86 words
A system or bin as in claim 1, wherein all of said shelves have substantially uniform longitudinal dimensions and substantially uniform transverse dimensions from shelf to shelf, said shelves being constructed and arranged so that said first longitudinal side edges of said shelves are aligned in a first vertical plane along said first longitudinal side of said system or bin and said second longitudinal side edges of said shelves are aligned in a second vertical plane along said second longitudinal side of said system or bin.
Claim 6
Dependent Claim
45 words
A system or bin as in claim 1, wherein said alternate shelves lie in planes comprising a first set of oblique planes parallel to one another and another set of oblique planes parallel to one another and oblique to said first set of oblique planes.
Claim 7
Dependent Claim
29 words
A system or bin as in claim 5, wherein all of said shelves lie in oblique planes whose obliquity defines an angle with the horizontal not exceeding 15 degrees.
Claim 8
Dependent Claim
46 words
A system or bin as in claim 1, wherein said zig-zag vertical arrangement provides alternate elongated access openings along opposite longitudinal sides of said system or bin to vertically adjacent of said compartments for operators working simultaneously along opposite longitudinal sides of said system or bin.
