摘要： A chair control mechanism is provided for use on a chair having a separate seat 14 and backrest 16 that move with respect to a base 12 of the chair. The mechanism 22 includes a housing 26 supported on the base, and brackets 28, 30 secured to the seat and backrest. The seat bracket 28 is supported on the housing for pivotal movement about a horizontally extending front pivot axis 68 between an upright position and a reclining position, and the front pivot axis is located adjacent the front end of the housing. The backrest bracket 30 is supported on the housing for pivotal movement about a horizontally extending rear pivot axis 80 that is located rearward of the front pivot axis. A mechanical linkage 70, 78 is connected between the brackets at a position spaced rearward of the rear pivot axis relative to the housing for transmitting pivoting movement between the brackets, and a spring assembly 32 is connected between the housing and the backrest bracket for biasing the seat and backrest toward the upright position. A forward travel-stop control assembly 38 is provided on the mechanism for adjusting the forward most position of the seat and backrest, as is a tilt control assembly 36 which permits the seat and backrest to be locked against tilting movement. The tilt control assembly 36 includes a locking plate 102 supported on the housing for relative translational movement between an extended position in which the locking plate is received in an aperture of the backrest bracket to lock the backrest bracket from further pivotal movement, and a retracted position removed from the aperture to allow further pivotal movement of the seat and backrest. A locking pawl 106 is supported on a lever 104 of the tilt assembly and engages the lock plate 102 to retract and extend the plate when the lever is rotated. In addition, a clutch is interposed between the actuating lever and the locking pawl for exerting a rotating force on the locking pawl to move the locking pawl from the second position when the actuating lever is rotated. The rotating force of the clutch is smaller than the friction force that is exerted on the locking plate when the pivoting force of the spring assembly 32 is exerted on the locking plate such that the locking plate can only be retracted when the friction force is reduced to a magnitude less than the rotating force.

摘要： An adaptor housing assembly for mounting an adjustable height work surface to a wall panel of an open office furniture system. The wall panel has a pair of vertical slotted standards which are adapted to receive the hooks of a mounting bracket. The adaptor housing assembly mounts a height adjustable work surface to the vertical slotted standards of the wall panel by clamping a mounting bracket to an adaptor housing in which is mounted a height adjustment mechanism having a frame which is connected to the work surface. The adaptor housing is fixed with respect to the wall panel and the frame of the height adjustment mechanism moves vertically with respect to the wall panel to raise and lower the work surface. The channel guides the moving members of the mechanism to which the work surface is mounted. The adaptor housing has a pair of elongated flanges extending outwardly from one end of the adaptor housing to form a slot which receives an elongated plate having tapped holes. The mounting bracket is affixed to the adaptor housing by screws passing through the mounting bracket and into tapped holes in the elongated plate, thereby clamping the mounting bracket to the adaptor housing as the screws are tightened. The hooks of the mounting bracket engage the vertical slotted standards and support the adaptor housing to which the work surface is mounted by the height adjustment mechanism.

摘要： A chair of the type used in theaters or the like includes a seat mounted to a standard by pivot mechanisms which bias the seat to a three-quarter fold position in which the seat is raised to permit row egress. The chair back is pivotally mounted for rotation about a horizontal axis located in the back area of an occupant. A link connects the specially formed seat frame to the lower part of the back frame so that when the seat is in the three-quarter fold position, the top of the chair back is rotated forward so that the chair back assumes a generally vertical disposition thereby increasing egress room for the occupant of the row to the rear. Also, in the three-quarter fold position the link/frame mechanism locks the back panel in that position so that it cannot be displaced should an occupant of the next row to the rear grasp the back panel and use it to steady himself or pull himself out of his seat. When the seat is lowered for use, the link rotates the back panel to a normal inclined position for occupant comfort.

摘要： In a chair having a base, a seat, a backrest, and a tilt control mechanism, a horizontal adjustment mechanism is provided for allowing fore and aft shifting movement of the seat relative to the backrest. The tilt control mechanism typically includes a pair of rails or other mounting structure by which the control mechanism is normally fastened to the seat. The rails present a pair of laterally spaced longitudinally extending edges and a plurality of mounting holes arranged in a predetermined pattern. The horizontal adjustment mechanism includes a seat mounting assembly provided with a pair of laterally spaced guides adapted to engage the edges of the rails to support the seat mounting assembly for sliding movement on the control mechanism. The seat mounting assembly presents at least one plurality of mounting holes by which it can be fastened to the seat, and these mounting holes of the seat mounting assembly are arranged in the same pattern as the holes in the rails so that the horizontal adjustment mechanism can be employed on the chair without requiring modification or added expense. Likewise, by employing the rails of the tilt control mechanism to support the guides of the seat mounting assembly, a low profile is presented that reduces the overall height of the seat above the ground.

摘要： Modular wall panels and ancillary furnishings and fixtures, such as shelves and cabinets, having a single load-bearing connector post between two coplanar panel members. The panel members engage apertures in the side walls of the connector post. The front and back walls of the connector post are vertically slotted with a width dimension to support hooks from two brackets within each slot, one from the left and one from the right sides of adjacent shelves, desk surfaces or cabinets. Thus, the connector posts directly support all of the system load without lateral force transfer from intermediate load bearing members. The load is transmitted vertically downward to a support surface, usually a floor. At intersections of non coplanar panels, a connector post terminates each planar panel run and is joined to a non load-bearing intersection post at a side wall of each connector post.

摘要： A J-back calibration device is adapted to vary respective positions of the seat and the back on a chair to which it is removedly attached. A chair measurement device is mounted to the seat of the chair and is adapted to take measurements of the chair given a set position of the J-back calibration device. A design of experiments software is provided with test condition information including the variable positions of the J-back calibration device and measurements from the chair measurement device. The software generates a table of configuration settings for the J-back calibration device at which shirt-pull and bridging or other such variable sought to be optimized can be measured and provided to the software. Through graphical and other analytical tools, optimal configuration settings for the variable positions of the J-back calibration device are determined. The J-back of a chair is adapted to these calibrated settings.

摘要： The invention is a crank which is flush-mounted into a work surface and provides for raising or lowering a vertically adjustable work surface. The crank can be raised from its stored position to a fixed position above the work surface and unfolded providing for rotating the crank to raise or lower the work surface by causing an adjustment screw to thread in or out of an adjustment nut. The crank is returned to its stored position or flush-mounted by folding the crank and pressing downward.
