A post coupler having a first body portion and a second body portion. Each body portion having an inner edge, an outer edge, a reverse flange, and at least one post alignment tab. Each reverse flange forms a post receiving slot. The first and second body portions are coupled to each other at approximately 90 degrees. A method of using the post coupler comprises the steps of a) providing a first post section and a second post section, b) inserting the first post section along the post receiving slots until the first notch interacts with the tab, and c) inserting the second post section along the post receiving slots until the second notch interacts with the tab.

Building or structural panels may be joined, such as to form walls or floors. The panels may be connected in various orientations via one or more connectors. The connectors may mount to anchors associated with the panels. The panels may have outer skins located over an expanded core comprising a matrix of supporting elongate members and voids or openings, with the anchors located at edges of the panels.

A connector hub assembly usable as a standalone module or as a component in a work space system. The connector hub assembly optionally includes features for connecting one or more arms of a support frame for supporting a modular workspace system including desk space, cabinet space, view screens, electronic equipment, and/or other workspace system components.

A column cover system includes a first column skin, a second column skin, and a column joint vertically connecting the first column skin and the second column skin. The column joint includes at least one monolithic column joint portion that defines an upper retaining ring and a lower retaining ring. When assembled, the first column skin is seated within the upper retaining ring and the second column skin is seated within the lower retaining ring.

This disclosure provides spacers for smart windows. In one aspect, a window assembly includes a first substantially transparent substrate having an optically switchable device on a surface of the first substrate. The optically switchable device includes electrodes. A first electrode of the electrodes has a length about the length of a side of the optically switchable device. The window assembly further includes a second substantially transparent substrate a metal spacer between the first and the second substrates. The metal spacer has a substantially rectangular cross section, with one side of the metal spacer including a recess configured to accommodate the length of the first electrode such that there is no contact between the first electrode and the metal spacer. A primary seal material bonds the first substrate to the metal spacer and bonds the second substrate to the metal spacer.

A stacking ring for a chair base may be disposable between a first and second chair base such that the stacking ring generally prevents lateral movement of the first chair base relative to the second chair base. The stacking ring may be integrally formed to the chair base, or separate and disposable between at least two chair bases. The stacking ring may substantially prevent rotation of a first chair base relative to a second chair base.

Trench drains are hollow or grid-like bodies which can be installed in the ground and are intended to receive precipitated surface water and slowly dissipate it into the ground or to store the water. These hollow or grid-like bodies are constructed from individual drainage bodies which must be firmly connected together. Drainage body connecting elements are proposed for connecting drainage bodies, which comprise two pegs which are connected via a web and can each be inserted in a receiving orifice of a drainage body so the two drainage bodies can be connected together via the web.

The connectors may mount to anchors associated with the panels. The panels may have outer skins located over an expanded core comprising a matrix of supporting elongate members and voids or openings, with the anchors located at edges of the panels.

A connector includes at least two cavities or receptacles extending from a base to receive adjacent tubes of a wall or panel. The receptacles are closed at one end. At least two walls extend from the base in the same direction as the receptacles. The walls are positioned on the base and outside the receptacles such that the panels are secured to a specific angular orientation with respect to each other. A top connector and a bottom connector are used to secure rods or tubes of adjacent panels. A series of top and bottom connectors can be used to secure multiple panels to form an enclosure, such as a kennel or gazebo.
