Abstract
Abstract A chiropractic table having a feature that facilitates the treatment of rotatory scoliosis and scoliosis of the spine. The chest-lumbar section of the table is mounted so that it can both pivot and slide thus producing a swinging movement about a central pivot point located above the longitudinal axis of the table. This type of movement is beneficial in the treatment of scoliosis. The mounting structure of the chest-lumbar section is such that the section can be raised or lowered to accommodate the particular anatomy of the patient and also provides for inclusion in the section of the drop feature used in the treatment of scoliosis and other conditions.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
162 words
In a chiropractic table having a base and framework for supporting multiple independent sections that include a chest-lumbar section, a pelvic section and head and foot sections spaced longitudinally along the table, a supporting structure for one of the sections comprising a main frame connectable to the supporting framework of the table and providing first and second pivots spaced longitudinally of the table which pivots provide for pivotal connection along a horizontal longitudinal axis, a cradle assembly pivotally mounted on said first and second pivots, patient supporting means including a framework operatively connected to the cradle assembly so as to provide for limited movement of the patient supporting means relative to the cradle assembly and transversely of the table, said patient supporting means also including a patient engaging member controllably moveable vertically within a limited distance relative to the framework for the patient supporting means, and locking means to maintain the patient supporting means and cradle assembly in a selected stationery position.
Claim 2
Dependent Claim
162 words
In a chiropractic table having a base and framework for supporting multiple independent sections that include a chest-lumbar section, a pelvic section and head and foot sections spaced longitudinally along the table, a supporting structure for one of the sections comprising a main frame connectable to the supporting framework of the table and providing first and second pivots spaced longitudinally of the table which pivots provide for pivotal connection along a horizontal longitudinal axis, a cradle assembly pivotally mounted on said first and second pivots, patient supporting means including a framework operatively connected to the cradle assembly so as to provide for limited movement of the patient supporting means relative to the cradle assembly and transversely of the table, said patient supporting means also including a patient engaging member controllably moveable vertically within a limited distance relative to the framework for the patient supporting means, and locking means to maintain the patient supporting means and cradle assembly in a selected stationery position.
Claim 3
Dependent Claim
31 words
In the chiropractic table of claim 1 in which the connection between the framework of the patient supporting means and the cradle assembly provides for sliding movement transversely of the table.
Claim 4
Dependent Claim
69 words
In the chiropractic table of claim 2 in which the framework of the patient supporting means includes a pair of rods spaced-apart longitudinally of the table and extending transversely of the table, and the cradle assembly includes a pair of pillow blocks spaced-apart longitudinally so as to receive through them said rods, thereby providing for slideable movement between the framework of the patient supporting means and the cradle assembly.
Claim 5
Dependent Claim
98 words
In the chiropractic table of claim 3 in which there is affixed to the main frame an arcuate rack, the cradle assembly supports a shaft rotatable about a horizontal longitudinal axis and containing a pair of gears, one of said gears engaging the arcuate rack, and a second rack is affixed to the patient engaging member so as to be engagable with the second gear, said gear and rack arrangement providing for controlled pivotal movement of the cradle assembly relative to the main frame and controlled slideable movement of the patient supporting means relative to the cradle assembly.
Claim 6
Dependent Claim
45 words
In the chiropractic table of claim 4 in which the locking means is secured to the main frame and includes a locking member selectively moveable into and out of engagement with one of the gears of the gear-rack assembly to prevent said gears from rotating.
Claim 7
Dependent Claim
40 words
In the chiropractic table of claim 5 in which the framework of the patient supporting means includes a drop mechanism for controlling the relative vertical movement of the patient engaging member relative to the framework of the patient supporting means.
