Abstract
A table leg supporting a table top vertically above the floor is adjustable between minimum and maximum heights and adapted to receive a castor at the lower end thereof. The castor alters the minimum height of the table leg to be greater than the maximum height of the table leg without the castor. A spacer is removably mounted on the lower end of the table leg without a castor for increasing its height to be at least equal to and preferably greater than the minimum height of the table leg with a castor. Thus, tables supported by legs with castors can be positioned adjacent tables supported by legs without castors, and the adjacent tables can be adjusted to the same height by adding spacers to the non-castored legs.

In combination, first and second tables positioned adjacent each other and defining substantially horizontal worksurfaces and respectively vertically supported by pluralities of first and second leg assemblies above a floor, said first and second leg assemblies each including a vertically elongate leg member and a height adjustable glide movably mounted at a lower end of said leg member and projecting downwardly therefrom for contact with a floor, said glide being adjustable between first and second positions defining first minimum and maximum heights of said leg assemblies, castors being respectively mounted to said glides on said first leg assemblies so as to define a second minimum height of said first leg assemblies, said second minimum height being greater than said first maximum height, and spacers respectively removably mounted to lower free ends of said second leg assemblies to define a second maximum height of said second leg assemblies, each said spacer including an elongate axial cylinder, a disk-shaped flange extending outwardly of said cylinder, and a skirt cantilevered from an outer periphery of said flange, a free edge of said skirt and a lower end of said cylinder being adapted to contact the floor, said skirt defining the height of said spacer which is added to said second leg assemblies so as to determine said second maximum height, said second maximum height being greater than or equal to said second minimum height, and said first and second leg assemblies being adjusted to a same height which at least equals said second minimum height so as to horizontally align the worksurfaces defined by said first and second tables.
In combination, first and second tables positioned adjacent each other and defining substantially horizontal worksurfaces and respectively vertically supported by pluralities of first and second leg assemblies above a floor, said first and second leg assemblies each including a vertically elongate leg member and a height adjustable glide movably mounted at a lower end of said leg member and projecting downwardly therefrom for contact with a floor, said glide being adjustable between first and second positions defining first minimum and maximum heights of said leg assemblies, castors being respectively mounted to said glides on said first leg assemblies so as to define a second minimum height of said first leg assemblies, said second minimum height being greater than said first maximum height, and spacers respectively removably mounted to lower free ends of said second leg assemblies, said spacers each including a coupling part and a foot part joined together, said coupling parts being removably mounted to the respective said glides, and said foot parts extending below the respective said glides to add height to said second leg assemblies and define a second maximum height of said second leg assemblies, said second maximum height being greater than or equal to said second minimum height, and said first and second leg assemblies being adjusted to a same height which at least equals said second minimum height so as to horizontally align the worksurfaces defined by said first and second tables.
A table leg for supporting a table top, said table leg comprising:
- an elongate main leg connectable to an underside of a table top for supporting same vertically above a floor;
- an elongate bushing received in and fixed to said main leg adjacent a lower end of said main leg, said bushing including an axial through passage and an outwardly extending flange at a lower end thereof, said flange contacting the lower end of said main leg, said passage being internally threaded adjacent an upper end thereof;
- an elongate adjustable glide received in said passage, said glide including external threads on an upper portion thereof and a radially outwardly extending flange at a lower end thereof, said glide further including a downwardly opening recess in the lower end thereof, said external and internal threads being intermeshed to axially fix said glide to said bushing and to permit rotation of said glide so as to determine maximum and minimum heights of said leg;
- and
- a spacer having a main body of significant height and a reduced diameter coaxial stem, said stem being removably fixed in said recess of said glide, said main body extending downwardly from said glide to increase the maximum height of said leg by the height of said main body;
- whereby said table leg is adapted to receive either a said castor or a said spacer so that a pair of table tops respectively supported by said table leg with said castor and said table leg with said spacer are adjustable to the same height above a floor.
