Abstract: An upright active-sitting seat provides a connection of a seating leg to a base through an articulating joint that allows the user to move a seat front to back and side to side, allowing a more active sitting that encourages blood circulation. The chair includes a seat supported by a post that is connected to a mount via a ball joint rod by a transverse rod that is routed through the ball joint rod end. By way of a coil spring that engages with the mount and the post, the post is spring biased to a home position relative to the mount. When using the chair, a person may move the seat from the home position to a comfortable seating position. When the person stands from the chair after using it, the chair returns to its spring biased home position.

Abstract: A shelving connector has symmetrical arms for locking insertion into metal shelving. The shelving and the connector preferably include radiused surfaces for safety and attractive appearance. The radiused edges of the metal shelving serve a dual function of stiffening the shelving and providing a receiver for arms projecting from the connector. The connector preferably has resilient tabs which are captured in apertures in the receivers. The connector can be advantageously formed from injection molded ABS plastic.

Abstract: A shelf and divider assembly comprising a rigid shelf unit with a plurality of shelves includes removable and collapsible fiberboard inserts which partition the shelf spaces laterally and vertically and which lock in place behind the corner posts of the shelf unit.A literature storage fiberboard insert is removably installed between rigid shelves by downward and inward folding of end locking segments on horizontal shelf panels to positions wherein the locking segments clear the corner posts of the shelf unit. After the fiberboard insert is in place between shelves, the end locking segments are folded outwardly to their normal positions of use wherein they extend behind the front corner posts.A fiberboard insert having vertical dividers for lateral filing is removably installed between rigid shelves by moving dividers on opposite ends of the insert into locking positions behind the corner posts of the shelf unit after the insert has been placed between rigid shelves.
