Adjustable therapeutic pillow

Claim 2

Adjustable therapeutic pillow apparatus comprising: a base; a first pillow member having a convex surface; a second pillow member having a convex surface opposite and spaced apart from the convex surface of the first pillow member; said first and second pillow members each including first and second pillow member elements separated by a gap, the width of the gap being adjustable to adjust the length of the pillow member; and, means for fastening the first and second pillow members to the base, the means being adjustable to permit variations in the distance the pillow members are spaced apart when fastened to the base.

Claim 3

The apparatus of claim 1 further comprising a spacer block located in each gap between pillow member elements, such that the convex surface of the pillow member is smooth.

Claim 4

The apparatus of claim 1 wherein each pillow member element includes a longitudinal slot in which the means for fastening is restrained for permitting adjustment of the gap between the pillow member elements.

Claim 5

The apparatus of claim 3 wherein a threaded member extends through the slot of each pillow member element for fixing the gap between the pillow member elements.

Claim 6

An adjustable pillow apparatus, comprising: a base having a horizontal planar upper surface and a horizontal planar lower surface; walls defining a plurlaity of transverse dovetail mortise slots in the upper surface of the base; a pair of transversely spaced-apart elongated pillow members, each pillow member being comprised of first and second pillow member elements; the first and second pillow member elements each having a lower planar surface in contact with the upper surface of the base; the lower surfaces of the pillow elements further including walls defining a plurality of longitudinal slots in the lower surfaces; a plurality of tightenable fasteners extending through and confined by the longitudinal slots of the pillow member elements; the fasteners being attached to tenon members slidably engaged in the mortise slots of the base upper surface, such that the first and second pillow member elements of each pillow member may be slidably translated in a transverse direction by sliding movements of the tenon members in the mortise slots and slidably translated in a longitudinal direction by movement of the fasteners in the longitudinal slots of the pillow member elements, with the pillow member elements being fixable with respect to the base by the tightening of the fasteners; each first and second pillow member element including at least one vertical transverse wall, the vertical transverse wall of each first pillow member element of a pillow member being separated by a gap from and in a parallel plane with the vertical transverse wall of the second pillow member element of that pillow member; a threaded rod extending between the first and second pillow member elements of each pillow member through registered threaded holes in the vertical transverse walls of the pillow member elements, each threaded rod including opposite handed threads on the two ends thereof such that rotation of the rod in one direction causes the first and second pillow member elements to be longitudinally translated towards each other to narrow the gap between the pillow member elements and rotation of the rod in the opposite direction causes the pillow member elements to be longitudinally translated away from each other; each first and second pillow member element further including an open longitudinal side for access to the threaded rod and the fasteners; at least one spacer block filling each gap between first and second pillow member element vertical transverse walls; and each first pillow member element, second pillow member element and spacer block having matched convex pillow surface segments such that each pillow member includes a smooth pillow member surface opposite the pillow member surface of the other pillow member.

Claim 7

An adjustable pillow apparatus, comprising: a base having a horizontal planar upper surface and a horizontal planar lower surface; walls defining a plurlaity of transverse dovetail mortise slots in the upper surface of the base; a pair of transversely spaced-apart elongated pillow members, each pillow member being comprised of first and second pillow member elements; the first and second pillow member elements each having a lower planar surface in contact with the upper surface of the base; the lower surfaces of the pillow elements further including walls defining a plurality of longitudinal slots in the lower surfaces; a plurality of tightenable fasteners extending through and confined by the longitudinal slots of the pillow member elements; the fasteners being attached to tenon members slidably engaged in the mortise slots of the base upper surface, such that the first and second pillow member elements of each pillow member may be slidably translated in a transverse direction by sliding movements of the tenon members in the mortise slots and slidably translated in a longitudinal direction by movement of the fasteners in the longitudinal slots of the pillow member elements, with the pillow member elements being fixable with respect to the base by the tightening of the fasteners; each first and second pillow member element including at least one vertical transverse wall, the vertical transverse wall of each first pillow member element of a pillow member being separated by a gap from and in a parallel plane with the vertical transverse wall of the second pillow member element of that pillow member; a threaded rod extending between the first and second pillow member elements of each pillow member through registered threaded holes in the vertical transverse walls of the pillow member elements, each threaded rod including opposite handed threads on the two ends thereof such that rotation of the rod in one direction causes the first and second pillow member elements to be longitudinally translated towards each other to narrow the gap between the pillow member elements and rotation of the rod in the opposite direction causes the pillow member elements to be longitudinally translated away from each other; each first and second pillow member element further including an open longitudinal side for access to the threaded rod and the fasteners; at least one spacer block filling each gap between first and second pillow member element vertical transverse walls; and each first pillow member element, second pillow member element and spacer block having matched convex pillow surface segments such that each pillow member includes a smooth pillow member surface opposite the pillow member surface of the other pillow member.
