It is understood that these distinctive elements may be incorporated into existing chair designs or combined, in whole or in part, into new designs.
- For clarity, elements of the invention may be easily understood with reference to the following non-limiting examples.
-
FIG. 1 depicts a chair embodying aspects of the invention. - As shown, the chair comprises a
chair base 100. As depicted, the chair base comprises wheel-bearinglegs 102. In one embodiment, wheel-bearinglegs 102 articulate or collapse. Articulation or collapse oflegs 102 may allow for a more compact profile and portability, as seen inFIG. 2 . In an alternate embodiment, the chair base is adapted for permanent or semi-permanent attachment to a floor. In such an alternate embodiment, the chair base does not comprise wheel-bearing legs but instead comprises a substantially horizontal flange, wherein are formed a hole or holes to receive screws or bolts for permanent or semi-permanent attachment to a floor. Comparable means for attaching the chair base to a floor may be substituted for the flange. In yet another embodiment, the floor to which the chair base is permanently or semi-permanently attached is the floor of a bus, aircraft, train, or other form of mass transit. Mounted onchair base 100, is asupport column 104. Preferably, the support column comprises amechanism 106 for adjusting the length of the support column, such as a pneumatic cylinder, and ultimately the height of the user when seated. Aseat base 108 is mounted on the support column. In the embodiment ofFIG. 1 , the seat base comprises apivot 110 to whichseat 112 of the chair is coupled, and asemicircular guide 111 that allows for control of the degree of seat pivoting by means of insertion points arranged along the outer edge ofguide 111. Coupling via the pivot allowsseat 112 to pivot along an arc so as to present an inclined, substantially horizontal, or declined position. In the present embodiment,seat 112 comprises a spring-loadedpin 109, aseat support 113, aseat pad 118, afront mount 114, and arear mount 116. In alternative embodiments the seat may comprise fewer components or additional components.Pin 109 ofseat 112 engages with the insertion points ofsemicircular guide 111 ofseat base 108 to determine the position ofseat 112. In alternate embodiments, other comparable means of securingseat 112 along its arc of movement may be employed. - Occupants of the chair are thus able to sit in an inclined, upright, or reclined position, based on the position of the seat along its pivot range. As seen in
FIG. 1 ,seat 112 comprises two mounts: afront mount 114 and arear mount 116. In alternate embodiments, any number of mounts may be used. The mounts of alternate embodiments may be located at positions other than the front or rear, such as a along the side ofseat 112.Mounts FIG. 4A . As used in this application, a securing means is any means or mechanism capable of establishing a permanent or non-permanent coupling with another structure. In one embodiment, mounts 114 and 116 comprise locking pin mechanisms, as seen inFIG. 1 . - In the embodiment of the securing means seen in
FIG. 4A , securing means 406 is a locking pin mechanism comprising arectangular guide bracket 408 and a spring-loaded, lockingpin 410. In the embodiment, therectangular guide bracket 408 finds use as a receiver for a member comprising one or more insertion points that engage with the matching, spring-loadedlocking pin 410 to establish a coupling. An example of such a member iscentral beam 400, described in more detail below, having holes as its insertion points. The spring of spring-loadedpin 410 provides tension to engagepin 410 with the insertion points of the member received byguide bracket 408. It is generally understood that any comparable means or mechanism for securing may be substituted for any of the locking pin mechanisms found in the chair of the invention. By way of example, securing may alternatively be achieved by using a threaded screw, for use with matched, threaded insertion points, rather than a locking pin mechanism. -
Seat pad 118 may take any shape suitable for supporting a seated user. Preferably,seat pad 118 is shaped as seen inFIG. 3 . As seen inFIG. 3 ,seat pad 118 is substantially symmetrical when bisected by a longitudinal axis, with the width being greater at the back, as referenced by the preferred user seating orientation, than at the front. - The chair of
FIG. 1 , also comprises amodular support member 122. InFIG. 1 , the modular support member is non-permanently and adjustably coupled to securing means offront mount 114. The modular support member may be readily coupled to securing means ofrear mount 116, as well. In alternative embodiments, the modular support member is coupled to other components of the chair, such as the seat base or the support column. Preferably, securing means ofmounts Modular support member 122 may support a variety of additional chair components. - In one embodiment seen in
FIG. 4 andFIG. 4B ,modular support member 122 comprises a substantially linearcentral beam 400 dividing into twoparallel arms Arm 402 angles so as to extend below the plane ofcentral beam 400 before angling to extend parallel withcentral beam 400 whilearm 404 angles so as to extend above the plane ofcentral beam 400 before angling to extend parallel withcentral beam 400.Central beam 400 andarms front mount 114 orrear mount 116 ofFIG. 1 . - The chair of
FIG. 1 comprises aknee support assembly 124. In the embodiment ofFIG. 1 , the knee support assembly is coupled tomodular support member 122. However, it is understood thatknee support assembly 124 may be coupled to other elements of the chair in alternate embodiments. - As seen in
FIGS. 5 and 5A , knee support assembly 124 (FIG. 5A ) comprises two independentknee support pads Assembly 124 further comprises a securing means 504. Preferably, securing means 504 is a locking pin mechanism of comparable structure and function to other locking pin mechanisms described herein.Assembly 124 further comprises pivot stops 506 and 508 for use in limiting the arc of rotation ofknee support pads Support member 122 is depicted inFIG. 5A to provide a point of reference, but does not comprise an element ofknee support assembly 124. In certain embodiments not shown, the chair may comprise a single knee support pad or more than two knee support pads. Each knee support pad is adjustably coupled toknee support pivot 126. In this embodiment,pivot 126 is a substantially linear and horizontal rod that allows a coupled knee support pad to pivot along an arc centered onpivot 126, as seen inFIG. 5A . In the present embodiment,knee support pads pivot 126 as seen inFIG. 5A . In an alternate embodiment, the knee support pads are mounted proximally along the pivot. In yet another embodiment, the knee support pads are mounted adjustably along the pivot such as by use of a threaded, drilled, slotted, or otherwise configured pivot that accommodates movement of the knee support pads along the length of the pivot and preferably accommodates securing of each knee support pad at a selected position such as by means of a locking pin mechanism as disclosed elsewhere, herein. When more than one knee support pad is in use, each knee support pad pivots independently of any other knee support pad, along an arc centered onpivot 126, as evident inFIG. 5 . Independent pivoting of knee support pads allows a chair of the invention to accommodate a wide range of user body type, seating positions, and leg positions. Further, independent pivoting offers users greater freedom of movement. As with other elements of the present application,knee support assembly 124 may find use as an improvement to currently existing chairs. - The chair of
