Abstract

Abstract This patent relates to an improved table useful in medical and related practices. More particularly, this invention comprises a table having a central portion which includes a flat generally horizontally disposed base, extending upwardly from said base, spaced apart first and second extendible supporting means, a first cushion supporting means pivotally attached to said extendible supporting means whereby said first and second extendible supporting means can be simultaneously extended to vertically raise and lower said first cushion supporting means while said first cushion supporting means is horizontal and said first and second extendible supporting means can also be differentially extended with respect to each other to tip said first cushion supporting means at an angle with respect to the horizontal; a second cushion supporting means connected by pivotal attachment to the upper end of said central portion and at one side thereof, a third extensible means carried by said central portion for providing pivotal movement of said second cushion supporting means around said pivotal attachment, a third cushion supporting means connected by pivotal attachment to the second cushion supporting means, extensible means carried by said second cushion supporting means for providing pivotal movement of said third cushion supporting means around said second cushion supporting means whereby said second and third cushion supporting means can be pivoted simultaneously or individually above and below the horizontal; a fourth cushion supporting means connected by pivotal attachment to the upper end of said central portion and at the opposite side thereof, a fourth extensible means carried by said central portion for providing pivotal movement of said fourth cushion supporting means around said pivotal attachment, a fifth cushion supporting means slidaby attached to said fourth cushion supporting means, extendible means carried by said fourth cushion supporting means for providing coplanar movement of said fifth cushion supporting means with respect of said fourth cushion supporting means to increase or decrease the distance therebetween, said fourth and fifth cushion supporting means being adapted to be simultaneously pivoted above and below the horizontal around said central portion.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 384 words
A table having a central portion which includes a flat generally horizontally disposed base, extending upwardly from said base, spaced apart first and second extendible supporting means, a first cushion supporting means pivotally attached to said extendible supporting means whereby said first and second extendible supporting means can be simultaneously extended to vertically raise and lower said first cushion supporting means while said first cushion supporting means is horizontal and said first and second extendible supporting means can also be differentially extended with respect to each other to tip said cushion supporting means at an angle with respect to the horizontal; a second cushion supporting means connected by pivotal attachment to the upper end of said central portion and at one side thereof, a third extensible means carried by said central portion for providing pivotal movement of said second cushion supporting means around said pivotal attachment, a third cushion supporting means connected by pivotal attachment to the second cushion supporting means, extensible means carried by said second cushion supporting means for providing pivotal movement of said third cushion supporting means around said second cushion supporting means whereby said second and third cushion supporting means can be pivoted simultaneously or individually above and below the horizontal; a fourth cushion supporting means connected by pivotal attachment to the upper end of said central portion and at the opposite side thereof, a fourth extensible means carried by said central portion for providing pivotal movement of said fourth cushion supporting means around said pivotal attachment, a fifth cushion supporting means slidably attached to said fourth cushion supporting means, extendible means carried by said fourth cushion supporting means for providing coplanar movement of said fifth cushion supporting means with respect of said fourth cushion supporting means to increase or decrease the distance therebetween, said fourth and fifth cushion supporting means being adapted to be simultaneously pivoted above and below the horizontal around said central portion, one or more of said pivotal attachments being operably connected to a potentiometer, and said potentiometer is in circuit with a motor which operates the extendible means associated with pivotal attachment, said circuit further including a resistance of predetermined value to bias said Potentiometer in a manner which corresponds to a predetermined position of said cushion supporting means with respect to said pivot attachment.
Claim 2
Dependent Claim 384 words
A table having a central portion which includes a flat generally horizontally disposed base, extending upwardly from said base, spaced apart first and second extendible supporting means, a first cushion supporting means pivotally attached to said extendible supporting means whereby said first and second extendible supporting means can be simultaneously extended to vertically raise and lower said first cushion supporting means while said first cushion supporting means is horizontal and said first and second extendible supporting means can also be differentially extended with respect to each other to tip said cushion supporting means at an angle with respect to the horizontal; a second cushion supporting means connected by pivotal attachment to the upper end of said central portion and at one side thereof, a third extensible means carried by said central portion for providing pivotal movement of said second cushion supporting means around said pivotal attachment, a third cushion supporting means connected by pivotal attachment to the second cushion supporting means, extensible means carried by said second cushion supporting means for providing pivotal movement of said third cushion supporting means around said second cushion supporting means whereby said second and third cushion supporting means can be pivoted simultaneously or individually above and below the horizontal; a fourth cushion supporting means connected by pivotal attachment to the upper end of said central portion and at the opposite side thereof, a fourth extensible means carried by said central portion for providing pivotal movement of said fourth cushion supporting means around said pivotal attachment, a fifth cushion supporting means slidably attached to said fourth cushion supporting means, extendible means carried by said fourth cushion supporting means for providing coplanar movement of said fifth cushion supporting means with respect of said fourth cushion supporting means to increase or decrease the distance therebetween, said fourth and fifth cushion supporting means being adapted to be simultaneously pivoted above and below the horizontal around said central portion, one or more of said pivotal attachments being operably connected to a potentiometer, and said potentiometer is in circuit with a motor which operates the extendible means associated with pivotal attachment, said circuit further including a resistance of predetermined value to bias said Potentiometer in a manner which corresponds to a predetermined position of said cushion supporting means with respect to said pivot attachment.
Claim 3
Dependent Claim 17 words
The device of claim 1 wherein control panels are provided at each side of said central portion.
Claim 4
Dependent Claim 17 words
The device of claim 1 wherein each of said cushion supporting means carries at least one cushion.
