Brief Patent Description - Full Patent Description - Patent Application Claims
CROSS-REFERENCE TO OTHER APPLICATIONS [0001]This patent application claims priority from Canadian Patent Application 2550385 "Workstation Module for a Reclinable Office Chair" filed in the Canadian Patent Office on Jun. 5, 2006. FIELD OF THE INVENTION [0002]This invention relates to desks and chairs and more particularly to a workstation module for a reclinable office chair. BACKGROUND OF THE INVENTION [0003]Office workers often suffer fatigue and lost productivity due to long hours spent seated at a desk. Over the years, office furniture manufacturers have responded with a variety of ergonomic office chairs and desks designed to alleviate this problem. One early solution was the advent of swiveling, and castered office chairs that permitted a worker to more easily multitask between different workstations (for example: to scoot between a typewriter and a nearby filing cabinet). The advent of computers resulted in even more sedentary workers so recent improvements have focused more on optimizing the ergonomics of their seating posture. Castered, swiveling and now ergonomically adjustable office chairs have therefore become ubiquitous in the office environment. [0004]Typically these ergonomic chairs possess a variety of mechanical controls for adjusting the chair's seat-height with respect to the floor, its angle between the seat cushion and seatback cushion, its overall tilt angle, its armrest height, its lumbar support etc. [0005]Various efforts have also been made to optimally position an ergonomic office chair with respect to the keyboard and display of a computer. Cooper (U.S. Pat. No. 5,056,864) provides the user with an optimal, recumbent posture by integrating the user's chair with a computer. May (U.S. Pat. No. 6,102,476) also provides an integrated chair/computer however it appears somewhat less ergonomic. Maddox (U.S. Pat. No. 6,056,363) provides yet another reclining "computer/chair". While these types of integrated solution may provide an ergonomic posture, they are massive, complicated and expensive. Furthermore, they cannot make use of existing ergonomic office chairs that a user may already have in their possession. [0006]Trimnell (U.S. Pat. No. 5,893,607) and Sher (U.S. Pat. No. 6,773,060) propose much simpler and inexpensive solutions that attach directly to an existing office chair. Such devices are relatively inexpensive however they provide no support to the user for a reclining work posture and are therefore ergonomically sub-optimal. Furthermore, their cantilevered geometry cannot support heavy work tools such as a CRT computer monitor. Furthermore, being attached to the chair, these devices encumber the user when attempting to stand up or sit down. [0007]Brown (U.S. Pat. No. 6,298,794) and Lin (6,425,631) propose compromise solutions having either a totally separate computer workstation module (Brown) or one that is quite easily moved to permit the user to sit down or get up (Lin). Neither device however facilitates a reclined working posture when used in conjunction with an existing ergonomic office chair. [0008]Therefore there continues to be a need for a computer workstation that is ergonomic, easy to assemble or disassemble and inexpensive to manufacture. OBJECTIVES AND ADVANTAGES OF THE INVENTION [0009]It is therefore an objective of the present invention to provide a reclining workstation module for use with existing reclinable office chairs and existing office desks. [0010]It is a further objective of the present invention to provide a compact and geometrically strong workstation module that supports the user's legs in a reclined posture when the office chair is reclined while simultaneously supporting a laptop computer at an ergonomically correct position. [0011]It is still a further objective of the present invention to provide a workstation module that has a minimum number of moving parts while still being adaptable to different sized users. [0012]Yet another objective of the present invention is to provide a workstation module optimized for use with laptop computer but that can optionally be augmented for use with desktop computers. [0013]It is a further objective of the present invention to provide a workstation module that exploits the adjustments available in the existing office chair with which it is used, thereby minimizing the number of moving parts. [0014]A further objective of the present invention is to provide a workstation module that can provide supplemental adjustability to fit the needs of particularly large or small users. [0015]Another objective of the present invention is to provide a workstation module that can either stand alone for use with a laptop computer or else be used in conjunction with an existing office desk for tasks involving a desktop computer. [0016]Another objective of the present invention is to provide a workstation module that enables users to quickly and easily change their work posture. SUMMARY OF THE INVENTION [0017]In order to satisfy the requirements identified above, my invention is a workstation module for a reclinable office chair. The chair comprises a mobile base supporting a seat having a top surface and a bottom surface. The seat includes an adjustable backrest, a left armrest having an upper surface and a right armrest having an upper surface. The base comprises a central telescoping column supporting the seat and a plurality of radially extending supporting members each having an inside end fixed to the bottom of the column and an outside end adapted to carry swivel castors for mobility. [0018]The workstation comprises a supporting base comprising a first base member being a cross-member having a first end and a second end, a bottom surface and a top surface, a second base member fixed near its mid point to the first base member first end and oriented perpendicular thereto and a third base member fixed near its mid point to the first base member second end and oriented perpendicular thereto thereby forming an H-shaped supporting base. The support base may also have a "T" configuration, an "O" configuration or a squared "C" configuration. The second and third base members each have first and second ends that are adapted to carry feet or castors to support the base off of the floor. The workstation further includes a vertical column having a first and second end. The first end is fixed to the centre of the first base member top surface and the second end is fixed to an angled support member adapted to support a tilting worktable having a top edge, a bottom edge, a left edge, a right edge, an upper working surface and a lower surface having a centre point. There are also provided a left leg support platform and a right leg support platform fixed to the vertical column. [0019]In one embodiment of the workstation a four-legged table may be used in conjunction with the workstation or the four-legged table may be incorporated into the tilting worktable.
