Abstract
Abstract A device for supporting the wrists of a keyboard operator or typist. The device includes a support member for supporting the operator's wrists, a mounting bracket adapted to be mounted on a base, a pair of connecting members respectively extending from the mounting bracket and the wrist support member, each of the connecting members having a slot disposed therein, and a pin extending parallel to the support member through each of the slots in the connecting member so as to respectively connect the pair of connecting members extending from the mounting bracket to the pair of connecting members extending from the wrist support member. In this manner, the wrist support member is pivotably adjustable relative to the mounting bracket about an axis which is disposed parallel to the mounting bracket, and the wrist support member is translatably adjustable in two directions angularly disposed with respect to one another. Therefore, the wrist support members are independently adjustable in three directions providing the operator with a large degree of adjustability.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
104 words
A support for supporting the wrist of a typist or VDT operator during operation of a keyboard, said support comprising: wrist support means for supporting said operator's wrist; mounting means for mounting said wrist support means to a base which is adapted to support said keyboard, such that said wrist support means is disposed in front of said keyboard; and articulating means connecting said wrist support means to said mounting means for allowing three-directional independent adjustability of said wrist support means, such that said wrist support is independently and/or simultaneously adjustable in both a horizontal and a vertical direction and is also pivotably adjustable.
Claim 2
Dependent Claim
104 words
A support for supporting the wrist of a typist or VDT operator during operation of a keyboard, said support comprising: wrist support means for supporting said operator's wrist; mounting means for mounting said wrist support means to a base which is adapted to support said keyboard, such that said wrist support means is disposed in front of said keyboard; and articulating means connecting said wrist support means to said mounting means for allowing three-directional independent adjustability of said wrist support means, such that said wrist support is independently and/or simultaneously adjustable in both a horizontal and a vertical direction and is also pivotably adjustable.
Claim 3
Dependent Claim
34 words
The support of claim 1, further comprising locking means for locking said wrist support means in a fixed position, said wrist support being lockable in any increment of its horizontal, vertical or pivotal range.
Claim 4
Dependent Claim
44 words
The support of claim 1, wherein said support means is pivotably adjustable relative to said mounting means about an axis disposed parallel to said mounting means and said support means and is translatably adjustable in two directions angularly disposed with respect to one another.
Claim 5
Dependent Claim
168 words
A support for supporting the wrist of a typist or VDT operator, comprising: wrist support means for supporting said operator's wrist; mounting means for mounting said wrist support means to a base; and articulating means connecting said wrist support means to said mounting means for allowing three-directional independent adjustability of said wrist support means. wherein said support means is pivotably adjustable relative to said mounting means about an axis disposed parallel to said mounting means and said support means and is translatably adjustable in two directions angularly disposed with respect to one another, and wherein said articulating means comprises: a mounting bracket; a pair of connecting members respectively extending from said mounting bracket and said wrist support means, each of said connecting members having a slot disposed therein; and a pin extending parallel to said axis through each of said slots so as to respectively connect said pair of connecting members extending from said mounting bracket to said pair of connecting members extending from said wrist support means.
Claim 6
Dependent Claim
168 words
A support for supporting the wrist of a typist or VDT operator, comprising: wrist support means for supporting said operator's wrist; mounting means for mounting said wrist support means to a base; and articulating means connecting said wrist support means to said mounting means for allowing three-directional independent adjustability of said wrist support means. wherein said support means is pivotably adjustable relative to said mounting means about an axis disposed parallel to said mounting means and said support means and is translatably adjustable in two directions angularly disposed with respect to one another, and wherein said articulating means comprises: a mounting bracket; a pair of connecting members respectively extending from said mounting bracket and said wrist support means, each of said connecting members having a slot disposed therein; and a pin extending parallel to said axis through each of said slots so as to respectively connect said pair of connecting members extending from said mounting bracket to said pair of connecting members extending from said wrist support means.
Claim 7
Dependent Claim
27 words
The support of claim 4, wherein said articulating means further comprises a linkage means interconnecting said mounting bracket to said wrist support means for providing stability thereto.
Claim 8
Dependent Claim
42 words
The support of claim 4, wherein said locking means comprises a friction means for frictionally securing one of said pair of connecting members extending from said mounting bracket to one of said pair of connecting members extending from said wrist support means.
Claim 9
Dependent Claim
89 words
The support of claim 6, wherein said friction means comprises: a friction member disposed adjacent one of said connecting members: a lever retainer fixedly secured to said pin adjacent said friction member: and a lever pivotably secured to said retainer, one end of said lever extending between said friction member and said retainer and another end of said lever extending away from said friction member and said retainer such that pivotable movement of said lever causes said one end thereof to press said friction member against said connecting members.
