fig1 is a perspective view of spine stretcher and aligner 11 which includes a base 13 with resilient members such as cushions 15 and 17 extending above the base . in the embodiment of claim 1 , the cushions are mounted on a rigid or semirigid base . cushions 15 and 17 are comprised of a resilient material such as rubber or foam plastic of the extra firm variety for reasons which will become apparent as the discussion proceeds . each of the cushions includes slots 19 and 21 which extend therethrough from the exterior of the pillow to channel 22 , which is formed between walls 23 and 25 of cushions 15 and 17 . opposed walls 23 and 25 terminate at upper arcuate edges 27 and 29 , which extend substantially the length of the cushions and base 13 . cushions 15 and 17 are configured such that the apex of edges 27 and 29 is nearest one end of the cushions . this provides the necessary curvature for the lower spinal area and the neck area , where the majority of the problems occur . dowels 31 and 33 may be inserted into slots 19 and 21 for purposes which will be discussed as the description proceeds . when these dowels are in place , such as shown in fig4 they have beveled ends 35 and 37 so as to substantially mate with the edge of the cushions . as can be seen from fig3 the outer surfaces of cushions 15 and 17 taper downwardly from edges 27 and 29 to the outer edges of base 13 . fig2 more clearly indicates the curvature of edge 27 , which has an apex nearer one end of cushion 15 than the other . cushion 17 is configured substantially the same so as to provide channel 22 . in the preferred embodiment , the channel is conformed so as to terminate in convex edges 27 and 29 . this results in the channel being narrower at its ends than at a selected point along edges 27 and 29 . this convexity is designed so that the width of the channel is greatest at the apex of edges 27 and 29 . as previously indicated , this apex is preferably located approximately one - third of the distance from one end of the cushions . as an example , if the structure is mounted on a base approximately ten inches wide and fifteen inches long , each of the cushions would be approximately four inches wide , with top edges 27 and 29 forming an exaggerated lordotic - shaped curve with the apex being five inches from one end and ten inches from the other end . in this particular instance , when the , cushions are placed at the edge of the base , inner edges 27 and 29 form channel 22 extending the distance of the base , with the channel being two inches at each end and two and one - half inches wide at the apex . as specifically constructed , this particular embodiment includes a channel which has zero depth at each end and a two and one - half inch depth at the apex of edges 27 and 29 . fig5 illustrates the effect of inserting dowel 31 into slot 19 of cushion 15 . while it is understood that both dowels would be used together , or neither would be used if not desired , fig5 illustrates that the use of the dowel increases the height of edge 27 over that without the dowel , which is illustrated by edge 29 . slots 19 and 21 are located substantially directly below the apex of the associated edge of the cushion . these dowels may be used where cervical or other spinal areas require a more convex or higher arched lordotic surface . it is understood that any particular size of dowel may be used so as to provide varying adjustable heights . as indicated in fig4 holes 49 may be provided in base 13 so as to provide a means for placing a cord for carrying or hangup storage . fig6 illustrates the device in use with an illustration of the cross - section of a spinal column resting over channel 22 . this illustration shows how the downward pressure of the body itself causes movement of edges 27 and 29 in a direction away from their uncompressed position ( shown in dotted lines ) and toward each other , as shown by the solid lines . the concave configuration described above is required to keep the high points or apexes of the cushions from closing too much toward the center as one initially lowers his weight onto the device . the channel needs to remain open sufficiently to allow body pressure to build substantially before the channel narrows appreciably . the addition of one &# 39 ; s torso weight onto the cushions , as shown in fig7 strengthens the reaction pressure or force exerted by the cushions against dislocated spinal members which protrude and need realignment . each cushion is tapered in convex arcs from the upper edge of the channel to the outer edge of the cushion , with the bulk of extra firm cushion material being nearest the channel . the curvature of the cushion surfaces are designed to ensure that the cushions &# 39 ; reaction to one &# 39 ; s body weight is to produce concentrated lateral force moments pushing any protrusions , where weight is greatest , toward the center of the alignment channel . this ensures pressure realignment of those spinal members nearest the center of the channel . displaced members or tissue adjacent to the channel also experience some lateral energy forces until they move into proper alignment . referring again to fig6 the body weight rests mostly on the apex of edges 27 and 29 , which moves the body parts in contact or near it towards the center of channel 22 . as the body relaxes and exerts more weight onto the apex , the cushions exert increasing reactive force to realign dislocated spinal members and improve alignment of the spinous process , mammilary process , transverse process , and related nearby tissues . progressively , the realignment continues away from the apex , up or down the spinal column toward each end of the channel . this is a gradual occurrence as relaxation sets in . fig8 discloses a modification of the embodiment of claim 1 wherein cushions 41 and 43 have inclined walls 45 and 47 , with the channel being narrower at the top than at the base . this results in increased lateral force on displaced members or tissue . fig9 and 10 show a further modification of the apparatus of fig1 . the resilient means 51 and 53 and base area 55 are molded as one piece from a material such as polyethylene . channel 57 is not as deep since this construction requires a base having a greater depth . in this configuration , bottom 59 of channel 57 has an arcuate configuration with the apex of the bottom being substantially beneath the apex of curved edges 61 and 63 . in this embodiment , it is preferred that the channel bottom be rounded . a spine stretcher and aligner such as shown in fig9 and 10 provides a device which is substantially lighter , which reduces shipping costs and makes it easy to carry . the present invention has been tested and proven to be an effective means for individual treatment of back problems and specifically problems relating to stretching and alignment of the spinal column . the above description and drawings are illustrative , only , since modifications could be made without departing from the invention . for instance , the arcuate resilient edges could be created by means other than cushions , such as resilient arcuate means carried by supports secured to the base . accordingly , the scope of the invention is to be limited only by the following claims .
a spine stretcher and aligner comprising a rigid or semirigid base having two members mounted thereon , with each member having a sustantially flat face , with the faces opposing each other so as to form a channel therebetween . each member has an arcuate configuration at the upper edge of the face , with the highest point of said edges being closer to one end of the channel than the other . the members are composed of a compressible material which permits movement of the material toward the center of the channel when the weight of the back presses downwardly on the members . dowels may be removably inserted in the members so as to raise the height of the edges .
