Modular shelving
An adjustable shelving assembly is provided with four corner members of L-shaped cross section, either half of each corner member including aperture members each including an upper, larger circle and a lower, smaller, vertical hole overlapping the larger circle thereof; at least one group of four interconnecting members each including upper and lower aperture elements and a through hole between the aperture elements, each aperture element including an upper, smaller, vertical hole and a lower, larger circle overlapping the vertical hole thereof; elongated retainers each including two enlargements at both ends respectively, an annular groove adjacent to one enlargement, and an annular shoulder between the groove and the other enlargement; lock pins each having a substantial portion fastened in the larger circle of the aperture member and the through hole; and at least one flat shelf each anchored on tops of the interconnecting members.
1. An adjustable shelving assembly comprising:
four corner members of L-shaped cross section, each corner member comprising two halves, and either half of each corner member comprising a plurality of spaced aperture members formed lengthwise, each aperture member including an upper, larger circle and a lower, smaller, vertical hole overlapping the larger circle thereof;
at least one group of four interconnecting members, each interconnecting member comprising upper and lower aperture elements and a through hole between the upper and lower aperture elements, each aperture element comprising an upper, smaller, vertical hole and a lower, larger circle overlapping the vertical hole thereof;
a plurality of elongated retainers each comprising two enlargements at both ends respectively, an annular groove adjacent to one enlargement, and an annular shoulder between the groove and the other enlargement wherein the aperture element is upside down relative to the aperture member such that the aperture element and aperture member are inverted relative to each other, a diameter of either enlargement is smaller than either a diameter of the larger circle of the aperture member or a diameter of the larger circle of the aperture element, and the diameter of either enlargement is larger than either a diameter of the vertical hole of the aperture member or a diameter of the vertical hole of the aperture element; and
a plurality of lock pins each comprising a head and a shaft extending from the head wherein the head of the lock pin has a diameter about the same as a diameter of the larger circle of the aperture member, and wherein the shaft of the lock pin has a diameter about equal to a diameter of the through hole and a length greater than a length of the through hole;
wherein the groove of the retainer is clamped by the vertical hole of the aperture member, the interconnecting member is engaged with the corner member, the shoulder of the retainer is clamped by the vertical hole of the aperture element, the corner member and the interconnecting member are retained by the retainer, and a substantial portion of the lock pin is fastened in the larger circle of the aperture member and the through hole.
2. The adjustable shelving assembly of claim 1 , further comprising at least one flat shelf each being anchored on tops of the interconnecting members in a friction fit.
3. The adjustable shelving assembly of claim 1 , wherein the shaft of the lock pin is flexible.
4. The adjustable shelving assembly of claim 1 , wherein the shaft of the lock pin is latched.
5. The adjustable shelving assembly of claim 1 , wherein the shaft of the lock pin is a hollow projection.
