Abstract
Abstract A device intended to be removably attached to the top of a door for supporting cervical traction apparatus. The device is particularly directed toward applying cervical traction at home or in a doctor''s office or where more elaborate traction support structure commonly found in a hospital, or the like, is unavailable. The device includes adjustable structure that adapts it to a variety of different doors having various thicknesses, i.e., it fits all common doors without the use of normal attaching devices and/or tools, e.g., screws, threaded clamps, screwdrivers, etc. A significant feature of the device is that it may be repeatedly attached to a door without marring or defacing the surface thereof so that when not in active use, it may simply be lifted off the top of the door and stored in any out of the way convenient location.

Claim 2
Dependent Claim
179 words
An over-a-door support for cervical traction apparatus having a head support including a head sling, a weight and a traction cord attached at one end to said weight and at the other end to said head support, said over-a-door support comprising a main support member including a vertical portion for contiguously engaging one side of a variety of different doors having various thicknesses and a base portion for extending horizontally outward from the side of the door, said main support member including an upper horizontal portion attached to said vertical portion adjacent the upper end thereof for reaching over the top of the door, bracket means coMprising substantially vertical platelike structure including a lower portion for engaging one side of the door and including an upper portion slidably attached to said upper horizontal portion and defining holding means including a transverse slot having inwardly and outwardly directed arcuate portions for holding said vertical portion in constant contiguous engagement with the door, and pulley means fixedly attached to said base portion receiving said traction cord intermediate the ends thereof. subjacent
Claim 3
Dependent Claim
255 words
An over-a-door support for cervical traction apparatus having a head support including a head sling, a weight and a traction cord attached at one end to said weight and at the other end to said head support, said over-a-door support comprising a main support member including a vertical portion for contiguously engaging one side of a variety of different doors having various thicknesses and a base portion for extending horizontally outward from the side of the door, said main support member including an upper horizontal portion attached to said vertical portion adjacent the upper end thereof for reaching over the top of the door, bracket means slidably attached to said upper horizontal portion for holding said vertical portion in constant contiguous engagement with the door, and pulley means fixedly attached to said base portion receiving said traction cord intermediate the ends thereof; said bracket means including platelike structure provided with a transverse slot adjacent the upper end thereof for slidably receiving said upper horizontal portion of said main support member, said platelike structure including an inwardly directed radius superjacent said slot and an outwardly directed radius subjacent said slot respectively defining the upper and lower surfaces of said slot for diggingly engaging the respective upper and lower surfaces of said upper horizontal portion of said main support member selectively along the length thereof so as to maintain a rigid substantially parallel relationship with said vertical portion of said main support member for engaging the opposite side of a variety of different doors having various thicknesses.
Claim 4
Dependent Claim
255 words
An over-a-door support for cervical traction apparatus having a head support including a head sling, a weight and a traction cord attached at one end to said weight and at the other end to said head support, said over-a-door support comprising a main support member including a vertical portion for contiguously engaging one side of a variety of different doors having various thicknesses and a base portion for extending horizontally outward from the side of the door, said main support member including an upper horizontal portion attached to said vertical portion adjacent the upper end thereof for reaching over the top of the door, bracket means slidably attached to said upper horizontal portion for holding said vertical portion in constant contiguous engagement with the door, and pulley means fixedly attached to said base portion receiving said traction cord intermediate the ends thereof; said bracket means including platelike structure provided with a transverse slot adjacent the upper end thereof for slidably receiving said upper horizontal portion of said main support member, said platelike structure including an inwardly directed radius superjacent said slot and an outwardly directed radius subjacent said slot respectively defining the upper and lower surfaces of said slot for diggingly engaging the respective upper and lower surfaces of said upper horizontal portion of said main support member selectively along the length thereof so as to maintain a rigid substantially parallel relationship with said vertical portion of said main support member for engaging the opposite side of a variety of different doors having various thicknesses.
