A storage apparatus includes trays, a shaft, a base element and two wheel assemblies. The shaft is inserted in the trays to connect the trays to one another so that each of the trays is rotatable between a withdrawn position and a spread position relative to a lower one of the trays. The base element is attached to the shaft. The base element is connected to a second one of the trays by a connecting element. The base element is located below the lowermost tray when the trays overlap one another. The first wheel assembly includes wheels attached to the lowermost tray. The second wheel assembly includes wheels attached to the base element. The wheels cover a first area when the trays overlap one another and cover a second area when the trays fully spread from one another. The first area is smaller than the second area.

A kitchen workspace and a method of organizing a kitchen workspace is set forth. The kitchen workspace is consolidated into a small footprint area with automated vertical storage shelves for storing and housing kitchen items and kitchen appliances. The automated storage shelves may be provided with electrical power for powering kitchen appliances found on the shelves. Kitchen appliances may be rotated around the automated storage shelves while the appliances are being used. A user of the kitchen workspace is able to stand in a fixed position and access all kitchen items and appliances without moving from the fixed standing position.

The present disclosure relates to semiconductor manufacturing, in particular to reticle rack systems. The teachings of the present disclosure may be embodied in a reticle rack unit including a frame with four uprights and multiple crossbars and four turnstiles. The frame may have a longest dimension defining a front side and a back side. The four turnstiles may be mounted to the frame to pivot around a respective rotational axis parallel to the four uprights. Each turnstile may define a plurality of reticle nests sized to hold reticles.

A storage device includes, in a box having an open front, a rotation mechanism section that rotatably holds a storage body that stores an object and is rotatable about a shaft extending along an up-down direction. The rotation mechanism section includes: a stationary rail affixed to a top surface of the box and including a guide groove open downward and forward and extending in a front-back direction and a guide body on a holding section protruding downward from a groove bottom surface of the guide groove; and a movable rail movable in the front-back direction along the guide groove in the stationary rail, coupled to the storage body via the shaft, and including: left and right sidewalls, a bottom wall, and a front end wall that define a receiving groove for receiving the guide body; and a top wall that forms a slit opening for receiving the holding section.

A rotary fitting for a cabinet with top and bottom walls comprises a rotating supporting column, a top and a bottom rotary mounts for the supporting column, and at least one shelf to be fixed to the supporting column. The supporting column has a main tube, a bottom element mounted to the main tube, and a height adjustment device for a height of the main tube above the bottom rotary mount. The height adjustment device comprises a screw and a nut screwed onto the screw. One of the screw and the nut is fixed to the bottom element, and the other is axially supported within the main tube and has a bevel gear. There is a guiding hole in the main tube adjacent to the bevel gear, through which the bevel gear can be engaged and rotated by a screwdriver crosstip.

A revolving shelf system including a drive track extending along at least one inner surface of a side wall of a cabinet. A shelf member has at least one end connected to the drive track, and a drive member is received within and along the drive track. The drive member is in engagement with the shelf member and is configured to drive the shelf member along the drive track. A stabilizing connection is formed between the shelf member and at least one inner surface of the cabinet. The stabilizing connection is configured to maintain the shelf member in a fixed orientation relative to the inner surface of the cabinet throughout movement of the shelf member along the drive track.
