## Title
Rotating organizer using jars or other containers for storage

## Abstract

An organizer that may be mounted on either a wall, wall to ceiling, ceiling, or many other ways, using limited space, and using jars or other containers for storage. Rotatable or cylindrical elongated attachment members allow the organizer to be attached to different surfaces. It has slats to which containers can be removably attached. The slats may be fixed in place, or one or more of the slats may be rotatable. If jars are used, their lids are fastened to the slats, and the jars can be opened by unscrewing them from their lids. There are handles on one end to rotate the storage system. A ratchet can prevent slipping. Because they are transparent, the containers allow the user to visually select what he or she is looking for. These containers can hold anything from hobby supplies to nuts and bolts. Potential applications range from garage organizing to commercial applications.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 is perspective view of the first preferred embodiment of the invention, showing large jars 10 containing items 12, and small jars 14 containing items 16. The jars are preferably made of transparent glass. Large jar lids 18 and small jar lids 20 are retained on rectangular slats 22 by screws, nails, glue or other suitable means. The jars are removably retained on the jar lids by external screw threads around the openings of the jars that engage internal screw threads in side walls of the jar lids. The slats are attached between two end members 24. The slats, end members, jar lids, jars and the items in them all rotate around the axle 26. The axle may either be a live axle that rotates with the slats, or it may be a dead axle that does not itself rotate. A ratchet 28 permits rotation in one direction only. Handles 30 that extend outward from the axle, and pass between the slats, permit manual rotation of the slats. Mounting bracket 32 has elongated surface attachment members 34, with apertures 33, are connected by pivots 35 to angled supporting members 36 to which axle supports 38 are welded. The two angled members are at opposite ends of the axle, with each of the angled members being perpendicular to the axle. The two surface attachment members are parallel to the axle, and can be attached to a surface. Each of the surface attachment members are attached to both of the angled members. The slats and end members are preferably made of wood, while the axle, supporting bracket and jar lids are preferably made of metal.
FIG. 2 is front elevational view of the first preferred embodiment of the invention, showing that opposite ends of the axle 26 are retained between the two axle supports 38, and that opposite ends of the elongated surface attachment members 34 are retained between ends of the angled supporting members 36 by pivots 35. Nails, screws, bolts or other fasteners can be inserted through the apertures 33 to retain the organizer to one or more surfaces. The elongated surface attachment members 34 can rotate 360 degrees on pivots 35, to enable the organizer to be fastened to a variety of surfaces having different angles.
FIG. 3 is a top view of the first preferred embodiment of the invention. FIG. 4 is a right side view of the first preferred embodiment of the invention. The organizer is shown in these drawings as it will be seen when attached to a single vertical surface. The slats are parallel to the axle, and are entirely separated by spaces between the slats, without any contact between the slats. Each slat is an equal distance from the axle. Each slat is an equal distance from neighboring slats (i.e., the two slats that are closest to itself). The slats are radially symmetric with respect to the axle. The jar lids have flat circular tops that are attached to the slats, and cylindrical sides with internal screw threads that can engage external screw threads around openings of jars, and the cylindrical sides extend outward from the axle.
FIG. 5 is a detail view of the second preferred embodiment of the invention, which is the same as the first preferred embodiment, except that it has a locking member 40, which is shown in an unlocked open position. The locking member is retained on an extension 42 from the supporting bracket 32. A knurled knob 44 can be manually rotated to move the locking member in and out.
FIG. 6 is a detail view of the second preferred embodiment of the invention, showing the locking member in an locked closed position, in which the end 46 of the locking member engages end member 24, thus preventing the end member from rotating, and thereby also preventing the slats and jars from rotating.
FIG. 7 is a front elevational view of the first preferred embodiment of the invention, showing the elongated attachment member rotated 45 degrees from its position shown in FIG. 2.
The slats may be fixed in place with respect to the end member, or one or more slats may be pivotally connected to the end members so that they can rotate three hundred sixty degrees on their longitudinal centers. FIG. 8 is a front elevational view of the third preferred embodiment of the invention, which is the same as the first preferred embodiment of the invention, except that it has one rotatable slat, showing the rotatable slat 48 in a first position, with a first set of rotatable jars 50 facing forward, having lids 52 attached to a first side of the rotatable slat, and containing items 54. The rotatable slat is connected to the end members 24 by pivotal attachment members 56. FIG. 9 is a front elevational view of the third preferred embodiment of the invention, showing the rotatable slat in a second position, in which it has been rotated ninety degrees from the first position, showing both the first set of rotatable jars and a second set of rotatable jars 58 attached to an opposite second side of the rotatable slat. FIG. 10 is a front elevational view of the third preferred embodiment of the invention, showing the rotatable slat in a third position, in which it has been rotated one hundred eighty degrees from the first position, with the second set of rotatable jars facing forward, having lids 60 attached to the second side of the rotatable slat, and containing items 62.
FIG. 11 is a perspective view of the fourth preferred embodiment of the invention, with the left end facing forward. The fourth preferred embodiment includes two triangular end brackets 64, between which are two cylindrical attachment members 66 connected near lower vertices 67 of the triangular end brackets. A left rotating circular end piece 68 and a right rotating circular end piece 70 are pivotally connected near upper vertices 72 of the triangular end brackets. Several slats 74 are each pivotally connected at their ends to each of the two end pieces. In each slat, open-topped containers 76 are removably retained in apertures (not shown in the drawings) in the slats. The containers may be snapped into and out of the apertures in the slats. The left end piece has openings 78 that can be used as handles to rotate the end pieces, slats and containers.
FIG. 12 is a perspective view of the fourth preferred embodiment of the invention, with the right end facing forward. The right end piece has circular handles 80 with grips 82 by which each slat may be individually rotated by hand. In the absence of such manipulation, the slats and their containers are self-leveling, i.e., gravity will cause the slats and their containers to rotate on the slats' pivotal connections to the end pieces, so that the open tops of the containers remain upward.
FIG. 13 is a top view of the fourth preferred embodiment of the invention, showing the pivots 84 by which the slats are connected to the circular end pieces. FIG. 14 is a front elevational view of the fourth preferred embodiment of the invention.
