Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention is related to tables having multiple tabletop positions. Specifically, the invention is related to a multi-position table adaptable for use while sitting and for use while standing.

2. Discussion of the Related Art

Tables that are designed for seated use have a tabletop surface that is generally spaced 30 inches from the base, i.e., a ground or floor surface, on which the table rests. Such tables are commonly used for dining or work and have a tabletop that is more expansive than a tabletop used for tables used while standing.

Standing-use tables are commonly found in conference areas or breakrooms where one or more users each rest a beverage, but generally not much more, on the tabletop. The smaller tabletop of a standing-use table has a different position the tabletop seated-use table; it is generally spaced 42 inches from the base and provides a more intimate space allowing users to have a conversation over the noise of others.

However, often facilities require multiple types of tables, including for seated use and for standing use, which may differ only in the position of the tabletop. Increasing the different types of tables required increases the logistical issues of storage, delivery, change-over from one type to another, and/or removal. Thus, what is desired is a table that has multiple positions, i.e., is a multi-position table.

In accordance with one or more embodiments of the present invention, a user wishing to change table 5 from a first table position 100a to a table position 100b disengages locking member 38 from the one or more column setting members 34a and/or setting members 32d and 32e by pulling it out. The user then rotates superstructure 10 to place table in position 100b and engages locking member 38.

Therein, table 5 is a sit-to-stand solution that has a mechanical locking and release system (opposed to hydraulic or electric components). Adjustor 30 comprises a “pull-pin” locking mechanism that preferably is located as far as possible from the pivot point while not making it awkward to reach. Consequently, there is less play in superstructure 10 when it is in a fixed location (either high or low). The further from the pivot point the smaller the angle of possible travel of the pin in its locked position.

In accordance with one or more embodiments of the present invention, adjustor 30 may include a hinge similar to a hinge used in a reclining seat that allows the lever to be parallel to the hinge so that it would stick out underneath the lower table surface.

While the invention has been described in conjunction with specific embodiments, it is to be understood that many alternatives, modifications, and variations will be apparent to those skilled in the art in light of the foregoing description.
