Desk for handicapped persons

A desk for use by a person of less than average physical strength, comprising:

• a desk top;
• a base for supporting said desk top;
• first means for mounting said desk top on said base to permit the adjustability of the height of said desk top, said first mounting means comprising means for facilitating said height adjustment of said desk top by said person of less than average strength;
• second means for mounting said desk top on said base to permit the adjustment of the angle of said desk top, said first and second mounting means each comprising:
• locking means for fixing the position of said desk top when said locking means is locked and for permitting adjustment in the position of said desk top when said locking means is unlocked;
• and
• frictional holding means for substantially maintaining the position of said desk top when said locking means is unlocked to further facilitate said adjustment in the position of said desk top by said person of less than average physical strength.

A desk for use by a handicapped person having less than average physical strength and manual dexterity, comprising:

• a desk top for supporting books, paper and the like;
• a pair of side plates, one of said side plates located on either side of said desk top;
• first means for rotatably mounting said desk top on said side plates to permit adjustments in the angle of said desk top;
• a base for supporting said desk top, said base being dimensioned and constructed to provide sufficient clearance beneath said desk top to accomodate a wheel chair or other supportive seating device that may be used by said handicapped person;
• two pair of substantially parallel lever arms providing means for adjusting the height of said desk top without changing its angular position, one of said pair located on either side of said desk top, each said lever arm attached at one end to one of said side plates and attached to its opposite end to said base;
• second means for rotatively mounting said one end of said lever arms to said side plates, said first and second mounting means each comprising:
• a pair of interlocking discs;
• operating means for manually selectively (i) engaging said interlocking discs to prevent rotating of one of said interlocking discs relative to the other and securely fix the position of said desk top, and (ii) disengaging said interlocking discs to permit adjustments in the position of said desk top;
• means biasing said interlocking discs to facilitate disengagement of said interlocking disc by said operating means;
• and
• at least one pair of frictional washers to provide means for substantially maintaining the position of said desk top when said interlocking discs are disengaged to facilitate adjustment in the position of said desk top by said handicapped person;
• third means for rotatively mounting said opposite end of said lever arms on said base, said third mounting means including a torsion bar to provide means for further facilitating said adjustments in the height of said desk top, said torsion bar and said fictional washers substantially equalizing the force of gravity acting on said desk top to maintain said desk top in position when said locking discs are disengaged.

An adjustable desk wherein the position of the working surface of said desk can be adjusted to suit the needs and desires of the user of said desk, comprising:

• a base;
• a desk top supporting said working surface;
• first means for mounting said desk top on said base to provide adjustability of the elevational position of said desk top relative to said base, said mounting means comprising:
• torsional means for facilitating the adjustment of the position of said desk top by biasing said mounting means;
• first locking means for selectively (i) fixing the position of said desk top when said locking means is locked, and (ii) permitting adjustments in the position of said desk top when said locking means is unlocked;
• and
• holding means cooperating with said torsional means for substantially maintaining the position of said desk top when said locking means is unlocked.

An adjustable desk adopted for use by users who may from time to time need to vary the position of the upper surface of said desk comprising:

• a base;
• a desk top supporting said upper surface;
• means rotatively mounting said desk on said base to permit the rotational adjustability of the position of said desk top about an axis;
• locking means for selectively locking the position of said desk top or unlocking said desk top to permit adjustment in the position of said desk top;
• and
• means for frictionally substantially maintaining the position of said desk top when said locking means are unlocked.

An adjustable desk, comprising;

• a desk top;
• means for mounting said desk top on said desk to permit the adjustment of the position of said desk top relative to said desk;
• locking means coupled to said mounting means for fixing the position of said desk top when said locking means are locked and for permitting adjustment in the position of said desk top when said locking means are unlocked, said locking means being biased to facilitate said unlocking;
• holding means connected to said mounting means for substantially maintaining the position of said desk top when said locking means are unlocked, said maintaining action of said holding means being assisted by said biasing of said locking means.
