This invention relates generally to tables for the accommodation of persons in recumbent or semi-recumbent position while undergoing therapeutic treatment and massage.
The object of the invention, generally stated, is to provide a table for accommodating persons undergoing therapeutic treatment or massage in recumbent or semi-recumbent position, and which is adjustable in a variety of ways, so as to best suit the physical condition being treated.
Another object of the invention is to provide a table of the character described having apparatus for vibrating the body resting thereon.
A further object of the invention is to provide a table of the character described, which is 001- lapsible into a convenient, compact unit for shipment and storage.
Other objects will become apparent to those skilled in the art when the following description is read in connection with the accompanying drawings, in which:

Figure 7 is an interior perspective view of the bottom portion of an upright frame showing the manner of connecting the base thereto; and
Figure 8 is a view in side elevation of the table when collapsed, as for storage or shipment;
The present invention contemplates a table of the character described having a central upright frame, mounted atop of which is a central section of the table, preferably upholstered. At opposite sides of the central section of the table, end-sections of the table are hingedly connected to the central section, so as to be adjustable into a variety of positions about the horizontal axis of said hinged connection. The central section of the table is also provided with a vibrating mechanism, and the end-sections are provided with supporting legs in positions remote from response to the vibratory impulses imparted to the end-sections by the vibrating center-section of the table.
Referring now to the drawings for an illustrative embodiment of the invention, the table comprises an upright supporting frame I having at the top thereof a central-table-section 2. on
2 opposite sides of the table-section 2, table-endsections 3 and 6 are provided. The end-sections 3 and i are connected to the central-section 2 by hinges 5 and 6, respectively, each having a horizontal hinge-axis.
Extending from the bottom of the upright frame I is a base frame consisting of a pair of bars I and 8, each hinged to the frame I by means of pins 9 and I0, respectively. One pair of such bars is shown clearly in Figure 2 and it will-be understood that a corresponding pair of such bars is provided at the opposite side of the frame I. At the extremities of the bars I and t, remote from their hinge-axes 9 and It. hinged legs are provided. In the embodiment shown, two sets of such legs are provided at the end of bars I, and a corresponding pair of sets at the end of bars 8. One set of legs consists of a pair of struts II one of which lies'adjacent each of the bars land i hingedly connected thereto by a' bolt or rivet I2. The upper extremities of the two struts I I (only one of which appears in Figure 2, but it will be understood that the companion part at the opposite side of the table is aligned therewith) are connected together by a rod I3 extending perpendicularly to the elevation shown in Figure 2. Likewise, a pair of shorter struts I4 are connected to the bars I by the hinge-pin I2. The opposite extremities of the short struts I i are connected together by a rod I5 similar to the rod I3 described above. A pair of feet I6 is hingedly mounted upon the rod I5 so that the feet depend therefrom and may have their opposite extremities resting upon the floor surface. I'he shorter struts I4 are arranged inside and closely adjacent the longer struts I I, so that both pairs of struts are freely movable about the hinge-axis I2 without interfering one with the other. A similar arrangement of struts is provided between the opposite bars 8.
Beneath the end-section 3 of the table, a pair of rails I7 is provided. Each of the rails has" a series of notches I8, the notches in the respective rails being aligned in the elevation shown in Figure 2, so as to receive selectively either the rod I3 or the rod I5 in any desired pair of notches. The rails I! are spaced apart a distance just less than the distance between the respective struts 54, so as to be receptive to either the rod !5 or the rod I3, depending upon the adjusted position of the end-section 3 of the table. A similar pair of rails is provided beneath the end-section 4 of the table.
With the arrangement of parts just described, a variety of positions is obtainable. The rod I3 may engage with one of the notches I8 to provide a horizontal position for the end-section 3, and with other notches to more or less elevate that end-section. Similarly, the rod I5 may engage with one or more of the notches I8 to adjust the end-section 3 to the dotted-line position shown in Figure 2 or to aposition intermediate the dotted-line position and the full-line po ition, i. e., horizontal. When the end-section 3 is in its lowermost position, the feet l5 are intended to rest upon the floor and thus relieve the struts M- of the major components of the load which would otherwise be imposed thereon. When the endsection 3 is in its lowermost position, indicated by dotted lines, the struts ii and their conjoining rod I3 may be folded back into the dottedline position. Likewise, when the end-section, such as i, is in its elevated position, struts and their conjoining rod I5 may be folded back into the full-line position shown beneath the endsection 4 of Figure .2. In order to accommodate such movement of the struts l I and M, the upper flange of the base-bars 1 and 8 may be cut away adjacent the hinge-pins 12.
The center-section 2 of the table may be resiliently mounted upon the frame I when it is desired to provide a vibrating table. In the embodiment shown, the resilient mounting comprises a plurality (four as shown in the drawings) of cushion-blocks 29, formed of rubber or the like, each having its lower end resting upon a bracket 2!, constituting a part of the frame I, and having its upper end engaging a bearingplate 22 (which may be the plate of hinge 5) secured to sub-base 24 of the center-section. From each end of blocks 20, studs 23 extend, and these are connected to parts 2! and 22, respectively. Sub-base 24 is countersunk to accommodate the end of stud 2 3 and its nut, at each posh tion. Adjacent each block is a bolt 25 extending through the sub-base 24 and through the bracket 21, but having a loose fit with each of them, so that the sub-base 24 is free for limited lateral movement relative to the bracket 2|. Surrounding the bolt 25, an anti-rattle-sleeve 26 may be provided if desired. The principal function of the bolts 25 is to prevent separation of the sub-base 24 from the frame I as by accidental uprooting of stubs 23 from the blocks 20. In addition to the series of blocks 28, there is provided a pair of coil-springs 30, each having its lower end resting upon a thrust-plate 3! (supported between opposite brackets .21 as shown in Figure 3), and its upper end engaging a bearing-plate 32 secured to the sub-base 24. The thrust-plate 3! is sustained by a pair of bolts 33, the nuts of which may be tightened or loosened to adjust the tension on spring 3!], as desired. Accordingly, in the embodiment shown, the center-section 2 of the table is resilient-1y mounted both through rubber cushion-blocks and coil-springs, each of which may be adjusted to vary the resilience and vibration characteristics of the subbase 24 of the center-section 2.
In order to impart a vibratory movement to the resiliently suspended center-section 2, any suitable vibrating device may be connected therewith. As shown in Figure 4 of the drawings, the vibrating device may take the form of an electric motor 48 secured beneath and to sub-base 24. The motor Ml has an eccentric fly-wheel d! so that, when the motor is operating, it and the parts upon which it is mounted are subject to vibration, the frequency of which depends not only upon the speed of the motor, but upon the adjustment of the several cushioning devices.
With the arrangement shown, the vibratory impulses imparted to center-section 2 of the table are delivered through hinges 5 and 6, re-
spectively, to the table-end-sections 3 and 4,
which are free to follow the vibratory movement in view of the double-hinge-connection existing between the struts H or [4 and the base-bars I and 8. Since the struts are hingedly connected with their cooperating members at both ends, relative movement between all of the parts is free to take place, so that the end-sections or the table may respond to the vibration of the center-section.
As shown in the drawings, the base-bars l and 8 are formed of channel sections and the ends thereof, between the hinge-pins 9 and Ill, are cut diagonally, as shown at l9, so that, when in their extended position shown in Figure 2, the diagonal ends thereof abut. In order to maintain the base-bars l and t in their extended position, an insert bar 2'5, of proportions such as to be received within the channel to bridge the diagonal cut 59, is provided. Any suitable means may be provided for retaining the insert bar 21 in position within the channel, as, for example, a pair of bolts 23, one at each end of the insert bar, passing through the same and the adjacent channel member. The insert bar 2? overlies the head of hinge-pins 9 and It within the channel.
When it is desired to collapse the structure, the insert bar 2'! is removed, so that the basebars I and 8 may hinge about the axes of pins 6 and ill assume the position shown in Figure 8. The struts i l and it, with their adjunct parts, may be removed from connection with the re spective base-bars or may be folded away, as desired. The endsections 1.3 and 6 are then free to be folded down alongside the frame I and collapsed base-bars '3 and as shown in Figure 8.
From the foregoing description, those skilled in the art should readily understand that the invention accomplishes its objects and provides a recumbent table of the character described, which is versatile in its disposition and makes possible a vibration of the complete structure, when and if desired.
