  • Patent number: 6843534
    Abstract: The present invention relates to an armrest apparatus installed in a chair for a computer work. An armrest member which is freely movable on a horizontal surface by a link apparatus is provided in an upper portion of an armrest body vertically installed at both sides of a seat of a chair. The armrest apparatus is used as a common armrest for a chair at a usual time on which a user's arms are placed in such a manner that an armrest member is closely contacted with an upper surface of an armrest body or is lifted upwardly. The armrest member is upwardly lifted at the height at which a keyboard work is conveniently performed during a computer work, so that a user's arms are freely movable on the armrest on a horizontal surface.

  • Patent number: 6773072
    Abstract: A vertically and horizontally adjustable chair armrest is disclosed. The armrest includes an outer shroud, an upstanding support with a central opening and an armrest base. Within the central opening is a guide tube that moves vertically and has oppositely disposed slots. Within the guide tube, but mounted to rotate only, is a rod. At the lower end of the rod is a locking element that extends through the slots in the guide tube. The rod is rotated by a user pivoted lever bearing down on a spring biased activator nut. The nut is keyed to move only in a linear direction but is threaded to engage a mating thread on the rod, thereby causing the rod to rotate. When the locking element is rotated out of engagement with notches in the support opening, the armrest may be adjusted in a vertical direction. Releasing the lever allows the spring to bias the locking element into engagement with the notches to lock the armrest.

    Abstract: An adjustable armrest assembly for a chair provides adjustment in both the vertical and horizontal position of an armrest member. A tubular member is adapted for telescopic mounting to an upwardly extending support member mounted to the chair. The support member includes a series of spaced teeth defining indentations therebetween. The armrest assembly includes a pivotable latch member which is secured to the tubular member utilizing a cap member mounted to the upper end of a passage defined by the tubular member. The cap member and the tubular member define cooperating mounting structure for providing pivoting movement of the latch member. The latch member is movable between an engaged position, in which the latch member is engaged with an indentation between the teeth defined by the support member, and a disengaged position in which the latch member is moved out of engagement with the teeth.

  • Patent number: 6419323
    Abstract: This invention provides an elevation mechanism for an armchair armrest, comprising a T-shaped post, a catch cylinder, an adjustment unit, a reflex plate, a U-shaped block and a resilient spring that are fastened by a plurality of screws. At the center of the T-shaped post is a U-shaped depression, on which are a first screw hole, a cross through hole and a second screw hole spaced from top to bottom. The first screw hole serves to fasten a first screw inserted in a first through aperture on the adjustment unit. The vertical slot of the cross through hole accommodates the insertion of the depressed groove of the adjustment unit. The horizontal slot of the cross through hole accommodates a U-shaped block that goes with the depressed groove. At the center of the adjustment unit is a third screw hole to accommodate and fasten a second screw inserted through the second through hole on the reflex plate.

  • Publication number: 20020036422
    Abstract: An arm assembly (24) is provided for a chair (12). The chair (12) has a forward direction and a rearward direction. The arm assembly (24) includes an armrest (26) and a support structure (28). A mounting device movably mounts the armrest to the support structure. The mounting device constrains the movement of the armrest (26) relative to the support structure to movement in a substantially horizontal plane having two degrees of freedom defined by first and second transversely arranged axes lying within the substantially horizontal plane. The armrest (26) thus move in a substantially planar fashion without changing the orientation of the armrest (26).

  • Patent number: 6352307
    Abstract: A seat, for example, a wheelchair, comprises a seat part, a backrest part, armrests, and footrests. The seat part and the backrest part have a commonly adjustable width, e.g. the side support portions can essentially be inserted into portions of a central frame part, and transversal bars in the backrest have adjustable widths. The seat part also has adjustable front and rear edges, obtained by adjusting adjustable front and rear support portions. The inclination of the backrest is adjusted by clamping screws mounted in side plate portions provided with slots. The height of the backrest can also be adjusted by displacing an upper portion thereof. The inclination of the footrests is varied by moving hinges having a large frictional force normally holding them stationary.

  • Patent number: 6302486
    Abstract: An armrest construction for chairs includes an armrest support having a lower end constructed for attachment to a chair, an upper end, and a mounting block attached to the upper end. A pivot block is pivoted to the mounting block at a main pivot, the pivot block having an upwardly-extending follower. First and second gears are each pivoted to the pivot block, the gears having intermeshing teeth at an inner end such that rotation of the first gear causes the second gear to simultaneously rotate in an opposite direction, the first and second gears further having outer ends. A support plate having pivot/slide members engages the outer ends of the first and second gears, and further has a guide operably engaging the follower to guide lateral movement of the support plate along a predetermined path.

  • Patent number: 6283551
    Abstract: An armrest has a cupholder at one end, and is adapted to be pivotally mounted between theater seats that have backrest portions. The armrest with the cupholder is pivotally movable from a generally horizontal position where it can support the arms of a person sitting in the seat, to a generally vertical position where it substantially fills the space between adjacent backrests, and provides a surface that forms a backrest continuation when the arm is pivoted upwardly. The armrest has pads at both the upper and lower surfaces thereof so that it is padded when it is being used as an armrest and also when it is forming a continuation of the backrest of the two adjacent seats.
