1. A retractable table device for mounting in a narrow space between the side of a mattress device on a bed frame rail, and comprising: a horizontal, laterally projecting base device to be sandwiched between the frame and the mattress device;an elongated stem device for mounting on one extremity thereof from the base device for rotation from a horizontal, retracted position disposed in the space to a vertical position and terminating in a free upper extremity;a pivot device rigidly mounted to the base device and mounting the one extremity from the base device for pivoting of the stem device about a single axis transverse to the length of the narrow space;a table formed with one end for mounting to the upper free extremity and pivotable between a retracted position disposed in the plane of the stem device and a working position perpendicular to the plane of the stem device;a hinge mounting the table to the free upper extremity;a support device for supporting the table in the working position. 2. The retractable table device of claim 1 wherein: the stem device is in the form of an elongated tube device. 3. The retractable table device of claim 1 wherein: the stem device includes an adjustment device for adjusting the length of the stem device. 4. The retractable bed table device of claim 1 wherein: the stem device is linear and the hinge is interposed between the free upper extremity and table for rotation of the table to the retracted position projecting along the same plane as the stem device. 5. A retractable bed table device for fitting in the narrow space between the side of a mattress device and a bed side rail comprising: an elongated stem device constructed for positioning in the space, having top and bottom extremities, formed medially with a pivot axis and projecting downwardly beyond the pivot axis to form a follower constructed to travel through a selected path from a downward retracted position to an erect elevated position;a laterally projecting base device to be interposed between the mattress device and a supporting frame;a mounting box on the base device for fitting in the space and having opposite side walls configured to fit the bottom extremity of the stem device and follower in close fit relationship to provide for rotation of the stem device through the predetermined path and for restraining the stem device against rotation in the plane including the pivot axis;a pivot device connecting the pivot axis of the stem device to the mounting box;the mounting box including first and second stops, the first stop disposed in the predetermined path to, when the stem device is rotated in one direction to the erect position, be engaged by the follower to stop the rotation in the one direction and the second stop being disposed in the path to, when the stem device is rotated in the direction opposite the one direction, be engaged to support the stem device in the retracted position; anda table pivotally connected to the top extremity for pivoting between a retracted position disposed in the plane including the stem device and a working position disposed perpendicular to the plane. 6. The retractable bed table device of claim 5 wherein: the mounting box includes a bottom wall supporting a vertical tab forming the second stop positioned to be engaged by the follower. 7. A retractable table device for mounting to fit in a narrow space between the side of a mattress device on a bed frame and a rail of a bed and comprising: a horizontal, laterally projecting base device to be sandwiched between the frame and the mattress device;an elongated stem device for mounting on one extremity thereof from the base device for rotation from a horizontal, retracted position disposed in the space to a vertical position and terminating in a free upper extremity;a pivot device rigidly mounted to the base device and mounting the one extremity from the base device for pivoting of the stem device about a single axis transverse to the length of the narrow space;a table formed with one end for mounting to the upper free extremity and pivotable between a retracted position disposed in the plane of the stem device and a working position perpendicular to the plane of the stem device;a hinge mounting the table to the free upper extremity;a support device for supporting the table in the working position including a bale carried pivotally from a free end of the table for shifting between a retracted position on the underside of the table to a supporting position to support the free end. 8. A retractable table device for mounting to fit in a narrow space between the side of a mattress device on a bed frame and a rail of a bed and comprising: a horizontal, laterally projecting base device to be sandwiched between the frame and the mattress device;an elongated stem device for mounting on one extremity thereof from the base device for rotation from a horizontal, retracted position disposed in the space to a vertical position and terminating in a free upper extremity;a pivot device rigidly mounted to the base device and mounting the one extremity from the base device for pivoting of the stem device about a single axis transverse to the length of the narrow space;a table formed with one end for mounting to the upper free extremity and pivotable between a retracted position disposed in the plane of the stem and device a working position perpendicular to the plane of the stem device;a hinge mounting the table to the free upper extremity;a support device for supporting the table in the working position including a bale pivotally supported from a free end of the table. 9.
