Ergonomic support device
First Claim
1. An ergonomic support device, comprising:
- a substantially vertical post having a lower end provided with means for supporting said device on a substantially horizontal surface;
a substantially horizontal, elongated support arm having a first end portion connected to said vertical post;
a substantially flat platform supported by a second end portion of said support arm,first adjustment means for adjusting the vertical position of said support arm relative to said support post, said first means being connected between said first end portion of said support arm and said vertical post;
second adjustment means for adjusting the length of extension of said support arm from said vertical post, said second means comprising portions of said support arm;
third adjustment means for connecting said first end portion of said support arm to said vertical post such that said support arm is pivotable relative to said vertical post;
fourth adjustment means for selectively tilting said platform relative to said support arm about a substantially horizontal axis spaced above said support arm, said fourth means being connected between a lower side of said platform and said support arm;
fifth adjustment means for translating said platform relative to said support arm in a back and forth direction of said platform, said fifth means being connected between said lower side of said platform and said support arm;
a pair of track members secured to said lower side of said platform in spaced apart, substantially parallel relation, and extending in the back and forth direction of said platform;
a support plate having opposite side edge portions thereof slidably received within said track members;
said fifth adjustment means comprising;
a lever comprising a handle portion extending below one end of said platform, and a pair of fulcrum portions extending from respective ends of said handle portion;
said fulcrum portions of said lever being pivotably connected with portions of said track members, respectively;
at least one of said fulcrum portions of said lever being provided with an extension which is normally biased into locking engagement with a portion of said support plate; and
said handle portion being movable so as to in turn release said fulcrum extension from locking engagement with said support plate, to permit back and forth adjustment of said platform;
sixth adjustment means for connecting said platform to said support arm such that said platform is pivotable relative to said support arm;
said second end portion of said support arm being provided with a substantially vertical bore; and
said sixth adjustment means comprising a substantially vertical support shaft having an upper end secured to said support plate and a lower end pivotably received in said bore of said support arm, and means for selectively securing said support shaft at a desired position within said bore.

Abstract
An ergonomic support device having a platform supported by a telescoping support arm which is in turn adjustably supported on a vertical post. The vertical post may be clamped to a desk, table, or the like so that the platform is elevated relative to a desk top, for example. The connection of the platform to the support arm provides for a wide range of adjustment of the platform, including tilting, pivoting, and back and forth translation. The device also provides for vertical and pivotal adjustment of the support arm relative to the vertical post, which further increases the range of adjustability of the platform. The adjustable platform supports reading materials and the like so that a user can stand while reading, writing, or performing other routine desk work, thus enhancing dynamic movement of a user who would otherwise be sitting in a sedentary position for lengthy periods.

7. An ergonomic support device comprising:
-
a substantially vertical post having a lower end provided with means for supporting said device on a substantially horizontal surface; a substantially horizontal, elongated support arm having a first end portion connected to said vertical post; a substantially flat platform supported by a second end portion of said support arm; means for connecting said platform to said second end of said support arm to permit said platform to be selectively tilted about a horizontal axis spaced above said support arm, selectively translated relative to said support arm in a back and forth direction of said platform, and selectively pivoted relative to said support arm; said connecting means comprising; a support plate slidably connected to a lower side of said platform; and a substantially vertical support shaft having an upper end pivotably connected to said support plate and a lower end pivotably secured to said second end portion of said support arm; a pair of track members being secured to said lower side of said platform in spaced apart, substantially parallel relation, and extending in the back and forth direction of said platform; said support plate having opposite side edge portions thereof slidably received within said track members; said upper end of said vertical support shaft being rigidly connected to a substantially horizontal shaft; said support plate having a sleeve secured to the lower side thereof, said sleeve extending substantially perpendicular to and between said track members; said sleeve being provided with a circumferential slot; said horizontal shaft being pivotably disposed in said sleeve, with said vertical support shaft extending downwardly through said circumferential slot of said sleeve; at least one plate member extending downwardly from said support plate, said plate member having an arcuate slot formed therein; a locking member extending through said arcuate slot and a through aperture formed in said vertical support shaft which is aligned with said arcuate slot; and said locking member being adjustable between an unlocked position in which a portion of said locking member slides within said arcuate slot to permit selective tilting of said platform, and a locked position in which said portion of said locking member is secured in position within said arcuate slot so as to prevent tilting movement of said platform. - View Dependent Claims (8, 9, 10, 11)
