Operator-interactive adjustable workstation

An operator-interactive adjustable workstation, comprising:

• a stationary support frame;
• a seat adapted for engagement with the buttocks of an operator;
• a generally horizontally enlarged worksurface having a substantially enlarged and planar upper surface;
• a motion connecting structure connected between said frame, said seat and said worksurface for permitting said seat and worksurface to be adjusted to multiple positions relative to said frame;
• an operator-interactive structure interconnected to said motion connecting structure for controlling position-adjusting movement of said seat and worksurface in response to an operator-imposed controlling force, said operator-interactive structure including an operator engagement member which is engaged by the operator and to which the operator imposes said controlling force;
• said motion connecting structure including a first support member which is movably mounted on said frame and which mounts said seat thereon, a second support member which is movably mounted on said frame and carries said worksurface thereon, a first connecting link which is movably connected between said first and second support members, and a second connecting link movably connected between said first support member and said operator-interactive structure;
• a manually-releasable brake cooperating with the motion connecting structure for normally maintaining said motion connecting structure in a fixed positional relationship to define stationary positions for the seat and worksurface;
• whereby, when said brake is manually released, said motion controlling structure can be moved in accordance with the controlling force imposed by the operator on the operator engagement member to adjustably move the seat and worksurface to desired adjusted positions, whereupon said brake is reengaged to hold the seat and worksurface in a newly adjusted position.

An operator-interactive adjustable workstation, comprising:

• a stationary support frame;
• a seat adapted for engagement with the buttocks of an operator, the seat having multiple positions;
• a generally horizontally enlarged worksurface having a substantially enlarged and planar upper surface, the worksurface having multiple positions;
• a motion connecting structure connected between said frame, said seat and said worksurface for permitting the positions of said seat and worksurface to be adjusted relative to said frame;
• an operator-interactive structure interconnected to said motion connecting structure for controlling position-adjusting movement of said seat and worksurface in response to an operator-imposed controlling force, said operator-interactive structure including a support member which is engaged by the operator and to which the operator imposes said controlling force;
• a manually-releasable brake cooperating with the motion connecting structure for normally maintaining said motion connecting structure in a fixed positional relationship to define stationary positions for the seat and worksurface;
• said operator-interactive structure including a control member which is movably supported on said frame and which mounts thereon the support member which is adapted for engagement with the foot of the operator;
• and
• whereby when the brake is released the operator's foot applies the controlling force to the support member to effect movement of the support member and of the control member to cause corresponding movements of the seat and worksurface, whereupon said brake is reengaged to hold the seat and worksurface in a newly adjusted position.

• a stationary support frame;
• a seat adapted for engagement with the buttocks of an operator;
• a generally horizontally enlarged worksurface having a substantially enlarged and planar upper surface;
• a motion connecting structure connected between said frame, said seat and said worksurface for permitting said seat and worksurface to be simultaneously adjusted to multiple positions relative to said frame;
• an operator-interactive structure interconnected to said motion connecting structure for controlling position-adjusting movement of said seat and worksurface in response to an operator-imposed controlling force, said operator-interactive structure including a support member which is engaged by the operator and to which the operator imposes said controlling force;
• a manually-releasable first brake cooperating with the motion connecting structure for normally maintaining said motion connecting structure in a fixed positional relationship to define stationary positions for the seat and worksurface whereby, when said first brake is manually released, said motion controlling structure can be moved in accordance with the controlling force imposed by the operator on the support member to adjustably move the seat and worksurface to newly adjusted positions, whereupon said first brake is reengaged to hold the seat and worksurface in the newly adjusted positions;
• and
• said motion connecting structure includes a second brake for maintaining said worksurface in a fixed positional relationship, whereby, when said second brake is released, said worksurface can be moved relative to said seat with said seat being stationarily positioned.
