United States Patent 3,180,604 ADJUSTABLE SUPPORT MEANS FOR A CASSETTE AND LIKE DEVICES Boyd F. Hammer, 4525 Bruce Ave., Minneapolis, Minn. Filed Aug. 2, 1963, Ser. No. 299,632

8 Claims. (Cl. 248-206) This invention relates to the general field of support devices and, more specifically, the instant invention pertains to support devices or means especially adapted for adjustment or manipulation whereby the supported article injury to those who may be attending a patient.

A further object of this invention is to provide adjustable support means for holding a cassette or similar article at a desired location relative to a patients anatomy, the supporting means holding the cassette fixedly and without motion whereby blurred and indistinct pictures are obviated since the means or device eliminates the holding of the cassette at the desired location through manual manipulation.

Another object of this invention is to provide a cassette holding device having a high degree of adjustability and which readily lends itself to field work, as well as in emergencies wherein it is impossible to bring into the fieldor the emergency area the elaborate X-ray equipment found in most modern hospitals.

This invention contemplates, as a still further object thereof, the provision of means of the type generally described supra, the means being relatively non-complex in construction and assembly, inexpensive to manufacture, and which is durable in use.

Other and further objects and advantages of this invention will become more evident from a consideration of the following specification when read in conjunction with the annexed draw-ing, in which: 7

FIGURE 1 is a top plan view of a cassette or X-ray film-holding device constructed in accordance with this invention;

FIGURE 2 is a longitudinal, medial detail cross-sectional view, FIGURE '2 being taken substantially on the horizontal plane of line 2'2 of FIGURE 1, looking in the direction of the arrows;

' FIGURE 3 is a bottom plan view of the adjusting assembly, partly in cross-section, FIGURE 3 being taken substantially on the horizontal plane of line 33 of FIGURE 2, looking in the direction of the arrows; and

.comprise a pair of identically constructed, spaced, suction cup assemblies'12 having a frusto-conical configuration. The suction cup assemblies 12 are preferably made ICC of cast aluminum and, as is seen in FIGURES l 'and 2, each suction cup assembly 12 includes a sidewall 14 which tapers upwardly to terminate in a base wall 16 disposed substantially in the plane of the frusturn. The lower end of each sidewall 14 is undercut to form a continuous circumferential groove indicated at 18 in which is seated a fiexible diaphragm 20 formed of rubber'or of some other suitable air-impervious material.

Each diaphragm 29 has a centrally-located, downwardly-facing cylindrical recess 22 (see FIGURES 2 and 4) which is in open communication with a centered passage 24 that extends transversely therethrough.

Each of the recesses 22 receives a discoidal plate 26 therein, and each plate includes a centrally-positioned internally-threaded cylindrical boss 28 that is received within each of the passages 24, respectively. Superimposed centrally over each of the diaphragms 2e, respectively, is a substantially fiat cylindrical clamp member 343 through the center of which extends a screw 32 that is threadedly received in the boss 28. Thus, as the screws 32 are tightened each diaphragm 20 is clamped between its respective associated discoidal plate 26 and the clamp member 30, in an air-tight manner.

Each of the base walls 16 is formed with a pair of transversely-extending, substantially centrally-located, diametrically-opposed openings 34 (see FIGURE 4) positioned above the clamp member 30, the pairs of openings each receiving for reciprocation therethrough, respectively, a pair of axially-elongated cylindrical standards 36. Each pair of standards 36 has a respective lower end reduced in diameter and threaded as at 38 for threaded connection within diametrically-opposed threaded openings 40 formed in the clamp member 3% (see FIGURE 4).

Reference numeral 42 indicates, in general, a bell-crank manually-operable lever for each suction cup 12. Each of the bell-crank levers includes a pair of oppositelydisposed, laterally-spaced, substantially parallel and identically constructed L-shaped sidewalls 44. The sidewalls 44 each comprises an elongated leg portion 46 and a relatively shorter foot portion 48. A bight wall 50 extends between and connects with the upper marginal edges of each pair of leg portions 46, respectively.

A bell-crank lever 44 is interposed between each pair of standards 36, respectively, and the heel portions 52 of each pair of sidewalls 44 receive transversely therethrough an elongated pivot pin 54 having opposed ends supported on the upper ends of each pair, respectively, of standards 36. Each pin 54 is telescoped through a spacer collar 56 which extends between adjacent pairs of heel portions 52 (see FIGURES 2 and4).

A shaft 58 extends between and is supported on adjacent pairs of foot portions 48 adjacent the free ends thereof and proximate a pair of edges thereof. Mounted on the shaft 58 is a lock roller at which is adapted to engage the adjacent base wall 16 when the bell-crank levers 42 are pivoted to their down position shown in FIGURE 2, and wherein the lock rollers 6t) are shown as having passed their respective dead-center position. Overrunning ofthe rollers 60 as they are moved to their locked position is prevented by engagement of the tips 62 of each pair of adjacent foot portions 48 with'the base walls 16, respectively.

" Reference numeral 64 connotes a pair of axially-elongated, substantially hollow cylindrical sockets, and each '3 :9 socket 64 is provided with an annular end wall 66. Each socket 64 is also formed with a pair of diametricallyopposed inwardly-extending slots 68, 79 which extend through the respective end walls 66.

Indicated at '72 are a pair of pedestals, each comprising a cylindrical base '74 and an upstanding throat 76 of reduced diameter, the latter terminating at its upper end in a sphere or ball 78. The pedestals '72 are each inserted through the open end of one of the sockets 64, respectively, the bases '74 passing through the annular end walls 65 after which the pedestals 72 are turned at substantially 90 to the direction of their entry to cause the spheres 78 to engage and seat against the adjacent end walled.

The bases 74 are fixedly connected to base walls 16 as ternal threads 84, 86, respectively. An elongated hollow,

tubular element 88 surrounds the member 82 and is provided at its opposed ends with internal left and right-hand threads 90, $2 adapted to be threadedly received by the threads 84, 86, respectively. To facilitate actuation of this adjustable holding device or means, the external central portion of the element 88 is preferably knurled as at 94.

From the above description it should be immediately apparent that the rotation of the tubular element 88 in one direction will cause the sockets 68 to be drawn toward the opposed ends of the tubular element 88 to cause the spheres or balls 78 to be rigidly clamped between the annular end walls 66 and their respective adjacent ends of the cylindrical member 82. Rotation of the tubular element 88 in the opposite direction releases this. clamping action to permit free swivelling action of' the spheres or balls '78 together with their attendant pedestals 72.

Referring now to FIGURE 2 of the drawing, reference numeral 96 designates, in dotted lines, a support member. The support member 96 may be a table, platform, or wall, or any other device having a substantially planar surface 96. Reference numeral 98 indicates, in dotted lines, a cassette or any other similar object also having a substantially planar surface d8. In this figure, the adjustable support means or device is shown in its operative position. That is, one of the suction cups 12 is illustrated as being connected to the base or support 96 and the other of the suction cups 312 is shown as being connected to a cassette 98.

The operation of the device is deemed to be selfevident from the foregoing description, but a brief explanation thereof is set forth below.

Again referring to FIGURE 2 and with the component elements of this invention asshown therein, to release the suction cups 12 from the cassette and base, it is only necessary. that the bell-crank levers 42 be turned in such directions asto cause the rollers 60 connected thereon to pass to the other side of their respective dead-center positions relative to the pivot pins 54 whereby the force exerted by the formerly distorted diaphragrns will cause the latter to move substantially flush with respect to the planar surfaces 96, 98', thereby breaking the vacuum. Of course, this also causes the standards 36 to move downwardly. The suction cups 12 may then be detached from their associated planar surfaces 96, 98'.

Turning the tubular element 88 in one direction releases the clamping action between the cylindrical member 82 and the sockets 64- whereby the suction cups 12 may be rotated about the vertical axes of the pedestals 72, or, if necessary, the pedestals 72 can be pivoted in one of the slots 68, 70. Again, the ball-and-socket type of connection permits the suction cup assemblies to be swung about the longitudinal axis of the cylindricalrnember 82.

After the desired adjustment has been made, the tubular element 88 is then turned in the reverse direction'to fixedly secure the adjusted positions and the bell-crank levers are turned in the opposite direction to cause the roller 66 to move to the off-center position shown in FIGURE 2, and in so moving, the standards 36, are elevated and draw their connected diaphragms 2i upwardly to cause a vacuum or a suction efiect between the diaphragms and theelements to WlliChth suction cups are to be connected.

While the' above description of the operation and assembly of this adjustable support has been ofifered in connection with a support for a-cassette, it will be readily understood that the description is given in order to provide an environment for the invention, for the device or means may beused in other fields of endeavor.
