 The present invention is directed to a work station, and more particularly, to a work station or desk having multiple work surfaces that can be easily positioned by the user.
 The rapid explosion of the use of computers, both in the home and work environment, has created a need for a work station that provides multiple work surfaces that can be easily positioned by the user. In addition, conventional computer work environments often contribute to user injuries and fatigue. Moreover, desired positions for computer system components will often vary based on the length of use, the type of work to be performed, and factors unique to the individual user, as well as other factors. Thus, it can be appreciated that there is a need for a work station that can quickly be adjusted to provide an ergonomic environment with multiple work surfaces for a particular use. The present invention provides these and other advantages, as will be apparent from the following detailed description and accompanying figures.
 The work station of the present invention provides a support structure to which multiple work surfaces can be attached in a wide variety of positions. In one embodiment the support structure includes a base for supporting the work station on a surface, a main post attached to the base, a plurality of support braces for supporting the main post relative to the surface, and a support assembly attachable to the main post for supporting a work surface.

The mount 136 may be pivotally attached to the adjustable boom assembly 134, and the work surface 138 may be pivotally attached to the mount 136. The work surface 138 is configured to support a variety of objects, such as a monitor, a keyboard, books, papers, and the like (not shown).
 The work station 100 illustrated in FIG. 1 has an optional first side post assembly 114 that includes a first side post 116 attached to a first side post base 118, and an optional second side post assembly 120 having a second side post 122 attached to a second side post base 124. As illustrated in FIG. 1, the second side post 122 is extendable in telescopic fashion. The second side post 122 has an inner sleeve 121 that frictionally engages an outer sleeve 123. One of skill in the art will recognize that various telescopic posts can be used. For example, a post held in place by friction may be used or a post held in place by a locking mechanism may be utilized. The center post 104 and the first side post 116 may also be extendable, and the second side post 122 may be fixed.
 The first brace 110 also is attached to the first side post assembly 114. The second brace 112 also is attached to the second side post assembly 120. The work station 100 includes an optional chase 126 attached to the center post assembly 102, the first side post assembly 114, and the second side post assembly 120. The chase 126 may house wiring (not shown) for use with various items, such as computers, monitors, keyboards, light fixtures and the like (not shown). Other components of the work station 100, such as the center post assembly 102, may also house wiring (not shown).
 As illustrated in FIG. 1, additional work surface support assemblies 140, 142, are attached to the first side post assembly 114 and the second side post assembly 120, respectively, for supporting additional work surfaces 144 and 146. (See FIGS. 3 and 4, discussed in more detail below). In addition, the work surface support assemblies 130, 140, 142, may support additional work surfaces (not shown). For example, the work surface support assembly 130 could support a work surface for a monitor (not shown) and a work surface for a keyboard (not shown), as discussed in more detail below with respect to FIG. 6.
FIG. 2 is an external view of another embodiment of a work station 101 of the present invention. In FIG. 2, the brace 112 is attached to a piece of furniture 150. An additional post assembly 160 is attached to the piece of furniture 150. FIG. 2 also illustrates a bookshelf 170 supported by the center post assembly 102 and the side post assembly 114.
FIGS. 3 and 4 illustrate a cam assembly 200 that can be used in work surface support assemblies, such as the work surface support assembly 140 shown in FIG. 1. A sleeve 202 is configured to be slidably and rotationally mounted on a post 204. A cam 208 is pivotally coupled to the sleeve 202 by a cam pin 206 in a cam holder 207. The sleeve 202 also has a mounting hole 210 through which an arm 212 for supporting a work surface (not shown) may be inserted. The cam 208 has a contact surface 209, a portion of which engages the post 204. In one embodiment, the cam pin 206 is positioned off-center with respect to the contact surface 209. Alternatively the contact surface 209 is formed to have a lobe that contacts the post 204 as the cam 208 rotates, thereby using frictional engagement to maintain the cam assembly in position on the post 204. Thus, the cam 208 is adjustable between a locked position, where the cam 208 will hold the sleeve 202 in position on the post 204, and an unlocked position, where the sleeve 202 can be repositioned on the post 204. The cam surface 209 may also be position in such a way that it does not engage the post 204 (not shown).
 In an exemplary embodiment, the cam 208 is configured to move into a locked position by the force of gravity. As illustrated in FIGS. 3 and 4, gravity will cause the cam 208 to move into the locked position when it is released. One of skill in the art will recognize that other mechanisms may be employed to move the cam 208 into the locked position, such as spring mechanisms, and the like.
FIG. 5 illustrates a work station 103 wherein a work surface support assembly 180 is coupled to the brace 112. FIG. 5 also illustrates multiple work surface support assemblies 182, 184, 186, 188, and 190 attached to side post assemblies 114 and 120.
FIG. 6 illustrates a work station 105 attached to a wall 602. As illustrated in FIG. 6, the work station 105 has a first beam 604 attached to the wall 602 by a plurality of braces 606, 608. A work surface support assembly 610 is attachable to the beam 604. A plurality of work surfaces 612, 614, are attachable to the work surface support assembly 610 in such a way that the positions and angles of the work surfaces 612, 614, are independently adjustable with respect to the beam 604. Additional work surface support assemblies 616, 618 may be attached to the beam 604 to support additional work surfaces 620, 622.
 A second beam 626 is attached to the first beam 604 using braces 628, 630. An additional work surface support assembly 632 is attached to the second beam 626. An additional work surface 634 is supported by the work surface support assembly 632.
 The position and angle of a work surface, such as work surface 612, may be adjustable using one hand. For example, the work surface support assembly 610 includes an extendable boom assembly 624 that is pivotally coupled to a sleeve 626 and that may be manually rotated by a user exerting rotational force on the work surface 612. At the same time, a user may be able adjust the length of the extendable boom assembly 624 by either pulling on, or pushing on, the work surface 612.
