14 Claims.

This invention relates to invalid beds, and has as its general object to provide a bed having a ushable toilet incorporated therein, eliminating lthe necessity for theuse of a bed pan.

Oneof the-objects of the invention is to provide for'supportingthe patient ina semi-upright positionA suiilciently approximating the normal position in the-use. of aA toilet, to permit a substantially normal use. More specically, the invention aims toprovidep in an invalid-sfbed, a.- flushable toilet arrangement in which the toilet bowl, in its operativeposition, is so inclinedas to permit the I body of the patient to be supported in a proper relationto the-bowl and in a comfortable reclining position. In vthev',conventional use of a bedpan, supported in a horizontal position, and with the patientxsupportedin ay reclining position, therefis atendency for the body of the patient to slide forwardly on the pana The-invention eliminates this difliculty by providing for the elevation of a thigh section of a sectional bed to an inclined` position, andbringing'the toilet-bowl to a corresponding `positionrso that the patient may be supportedl .between the thigh portion and an inclined back section, of the bed, with the toilet bowl in properposition for use.

Inzordei-thatthe .bowl maybe brought to a proper operative position with relation to a patient supported uponwthe:bed,;the.invention provides,for-presentingthe bowl through an, opening inthe bed.. Itis of coursedesirable that the bowl .bepremoved `.to an inoperative. position when not in use, and it is also desirable that it belooncealedinl the inoperative position., Consequently, aA further objectto the inventionis to provide for theconcealing of thefbowl beneathvthe bedwhen it is not inr use,andi for raisingthe bowl when it isto be used.

Another object ofthe invention is to provide for tiltingthe .bowl froma normally horizontal .position to a positionconforiningto the inclinationof the thigh section of the bed. To this end, the invention contemplates'hinging the bowl upon the elevating mechanism, and utilizing the contact of the bowl with the thigh section to cause the bowl to assume the angular position of the thigh section.

Another object of the invention is to provide for swingingth'ebowl horizontallyfrom beneath the bedy in order topermit of itsbeing used by anambulatorypatient.4 In connection `with this/general object, the invention. aims to provide a .bowl operating` mechanism that. isadapted to swing the bowlgireelyiand relatively noiselessly in a horizontalldirection; ToobtainI this object, the bowl .is

suspendedfby the elevating mechanism, for swing,- ing movement about a vertical pivot and insa position just clearing :the surface of the oor..

Another Objectis to provide'an invalids bed which, in addition to the above-mentioned fea.- tures, provides for supporting the weight of the patient upon the'bowl without imposingv allfof such weight upon the elevating mechanism: To.- ward the attainment of this general object,V one of the specific objects of ther invention is to pro'- vide meansfor latching the bowl'to the thigh section when the bowl completes its elevating movement. Theinvention also aims to eiiect this latching automatically as the result of elevating-movement. In addition, the invention contemplates that thebowl may beilatched to the thigh section of they bedin any position of angularity-ofwthe thigh section, evenv though the bowl is elevated about a hinge `axis which is considerably removed from the hinge axisof the thigh section.

In order to relieve the elevating mechanism. of at least a substantial vportion of the weight of the patient when the bowl is being used in the lowered and laterally projected position, the invention provides a yielding connection between the bowl suspension mechanism and the bowl itself, which permits the'bowl to move downwardly un,- der the weight'of the patient until it rests against the floor. When the weight of the Patient is -removed from the bowl, the bowl is tiltedl upwardly by this yielding connection and is thereby supported kout of Contact with the floor in order that it may be'swung horizontally without contacting the floor.

The yielding connection between the bowl and the suspension mechanism serves'the additional object of maintaining the `bowl normally in a vposition of maximum 11p-tilt so that the outer end of the bowl will always contact the thighs'ection before the `inner end of the bowl makes contact. The continued upward movement of the inner end of the bowl is then utilized toshift the bowl longitudinally with reference to the thigh section ofthe bed so as to effect the latching of the bowl to the thigh section.

Another object of the invention is to provide a bowl operating mechanism adapted to automaticallyV terminate the elevating movement ofthe bowl by cle-energizing the power means when the bowl has become latched to or properly positioned with reference to the thigh section.

Other, objects of the invention will appear in the followingA Specication when considered in connection `vviththe appended drawings, where- Fig. 1 is a plan view of an invalids bed embodying the invention, a portion of the bowl seat back rest being broken away to illustrate the bowl elevating mechanism therebeneath;

Fig. 2 is a longitudinal sectional View of the bed taken on the line 2-2 of Fig. 1;

Fig. 3is a partial longitudinal sectional View showing the bed mechanism in a position different from that of Fig. 2;

Fig. 4 is a detailed sectional view showing the limits switch for the elevating mechanism.

Fig. 5 is a partial sectional view of a modification of the invention;

Fig. 6' is a longitudinal sectional view of a I further modified form of the invention; and

Fig. '7 is a fractional sectional view showing an intermediate stage of elevating movement of the bowl.

As an example of one form in which the invention may be embodied, I have shown in Figs. 1-3'jinclusive an invalids bed including a head '9, a foot I0, xed longitudinal rails II secured to the head and foot as at I2, a toilet seat bed bottom section, indicated generally at I3, a removable bed bottom section, indicated generally at I4, and subir-ames I5 and I6 upon which the ltoilet seat section I3 and removable bed bottom Asection I4 are supported. The subframe I5 is -secured to the rails II as indicated at I1, and

the subframe I6 is mountedin any suitabie manner (as, for example, upon rollers) so that -it may be shifted laterally and removed from vthe bed and onto an ambulatory cart.

The toilet seat section I3 includes a leg portion I8, a thigh portion I3 having an opening,

and a back rest 20. The removable bed bottom vsection I4 includes a leg portion I8', a thigh portion I9', and a back rest portion 20. The

'leg portions I8 and I8 are hinged to the thigh portions I9 and I9 by hinges 2l, and the thigh portions I9 and I9' are hinged to the back rests and 20 by hinges 22. The hinges 22 are hinged to brackets 23 carried by the subframes I3 and I4 respectively. Consequently, the hinge axis joining the thigh section and back rests is a xed axis, while the hinged axis joining the leg sections and thigh sections is adapted to move upwardly and towards the thigh sections so that the bed sections may assume the position shown in Fig. 4 or any intermediate position of I elevation.

The bed bottom sections are generally of shallow construction, as shown, and are adapted to receive mattresses, the toilet seat mattress being indicated in broken lines at 24 in Fig. 3, and

-being provided with an opening 25 adapted to i register with the opening O in the thigh portion of the toilet seat section, in order to pro- -vide access to the toilet bowl 26.

The foot and head rests I8, I8 and 2li, 20 are adapted to be elevated by lifts each including a rack 21, the upper end of which is adapted to engage in `a socket secured to a respective bed Abottom section, a pinion 28 meshing with the tion.

The retraction of the racks 21 below the plane Iof the subframes permits the removable bed bottom section to be shifted horizontally without interference from the racks.

l The bowl 2E is carried by bowl suspension mechanism including an arm 32, having at one end a fork 33 hinged at 34 to a vertical shaft 35, and having at its other end a fork 36 in which a tail portion 31 of the bowl is pivoted as at 38. A compression spring 39, supported upon a guide rod 40, is engaged between the bowl and a cross bar 4I in the fork 36. The spring 39 yieldingly maintains the bowl in a position of maximum uptilt with reference to the arm 32. From this position of maximum uptilt, the bowl may yield downwardly, its outer end swinging downwardhT about the hinge 38.

Projecting from the respective sides of the bowl 25, on an axis intersecting the forward, upper extremity of the bowl, are a pair of latch pins 42, The pins 42 are adapted to engage the underside of the thigh portion I9 of the toilet seat, as the bowl 26 is elevated. Engagement is against a pair of inwardly projecting flange members 43 each having at its rear end a latch hook 44 (see Fig. 4). The pins 42 are adapted to be drawn into the hooks 44 as the bowl 25 reaches an operative position in the opening O, thus to latch the bowl to the thigh section I9, so that a substantial portion of the weight of the patient is transmitted directly to the thigh section and the elevating mechanism is relieved of this portion of the patients weight.

The elevating mechanism comprises a servomotor device of the linear pull type such as a hydraulic strut or screw jack. For the purpose of illustration, I have shown a servomotor pull device comprising an electric motor 46 adapted to drive, through planetary reduction gearing 41, an internally threaded sleeve 48 into which is threaded a rod 49. The rod 49 is pivoted at 50 in the fork 36, and the case of the motor 46 has a bracket 5I which is pivoted at 52 upon the shaft 35.

The upper and lower ends of the shaft 35 are journaled respectivelv in

brackets

53 and 54 secured to the head 3 of the bed.

The bowl 26 has the customary trap and outlet 55, and is connected to a sewer outlet 56 by means of a exible tube 51. Water for ilushing the bowl is injected through a flush valve 58 and a flexible hose 59 connected to the valve 58 and to a suitable water main outlet.

The 'shaft 35 has a loop portion 60 through which the exible tube 51 extends. Thus the axis of the tube 51 intersects the axis of the shaft 35.

Mounted in the thigh section I9 is a limit switch 6| which has a push button 62 extending through an opening in the hook 44 of one of the ange members 43, and is adapted to be engaged by a pin 42 when the bowl 26 reaches the operative position. The switch 6I is located in the circuit 63 through which the iield coil 64 of the motor 46 (which is a reversible motor) is energized. Such energization results in elevation of the bowl, and is terminated when the switch 6| is opened by the engagement of the button 62 by a pin 42. This energizing circuit may -be established initially by closing a switch in a control box 65. The other field coil 66 of the motor 46 is energized through a circuit 61 which includes one of the switches of the control box 65 but does not include the limit switch 6I. Consequently the fact that the circuit 63 is open does not prevent the bowl from being lowered. The lowering of the bowl is arrested when the fork 33 contacts the button of a limit switch 68 carried by the loop 6l oithel fshaftf; theslimitswitch-BB fbeing; imthe circuitl B1' vas-.showri-in E154: l

With the thigh section I9 in this position,.. the. pins 142`will` contact -the ange -members IBL-at -the extreme end: of thev thigh section, asindicated inlth'e-fiilllineposition off thebowl-'in Fig. 3.` The hinget` will then be located considerabl'yebelow the Ylevel of the thigh section... and the continued upward movement of the arm l32 will `movefthe hinge 38 upwardly untilit becomes/substantially coaxial `with'thehinge y 22 'between thethigh section andthe back rest 2li.v vThe bowl'w'ill then be infa `position-sl'rown'in dotted line-in Fig. 3, which is--in thei proper position ioruse.l In moving from thefposition shown Ain--iull lines tothe-position'shown indotted lines, thebowi 26 will shift longitudinally with reference to the thigh sec tion I 9, the pinsv 42sliding beneath theflanges 43 against which they are yieldingly urgedby the spring 39.` The spring 39 -will"-be compressed as the bowl 26--is forcedv to tiltupwardly at its rear end. Toward the end of this movement, thepins 42` will enter'the hooks 44'and whencompletely seated therein, the switch 6I will be opened, thus arresting/the operation of the'motor'46 and stop ping the bowl movement.

The bowl will now be Vsupported in the position as shown in dottedlines in Fig. 3,v with its forward end `carried by the hooks,l 44'and its rear end car;- r'ied lby the arm 32; 'Iheweight of thel patient, when he restsupontheb'owl., will therefore be distributed between thelatch hooks' 44 and the 11111'38.

In the event vthe leg. and thigh sections are raised to the positionszshown in Fig. 2V (representing the maximumelevation offthe leg and thigh section) the pin 42will rst' contactgthe fianges'43 justahead of Vthehooks M as indicated in Fig. 2. The amount o1. continued upward movement of the hinge 38 from its position of initial contact to the. terminal' position rshown in dotted'` lines .in Fig. 2 is mucl'i'less than thelinove.- ment illustrated in Fig.v 3'; but is .sufficient to draw the; pins 42,'into the hooks' 44.. The; terminal positionof the hinge .38,is in this .case, as in the other case, substantially coaxial.` with thehinge 22. By arranging to have thelhinge 3B `move to the axis ofr the hinges 22, it becomes possible to arrest the bowl ,movement when the. pins 42 are justseated in; the hooks 44,.rrespective of. the inclination ofthe thigh section I9and irrespective ofethefa'ct that the vvarmT 32 swings from a..-hing.e axis thatis considerably removed from. thehinge axisZZ.

The weight of the bowl normally maintains it in a horizontal position in which it is supported by the engagement with the bracket 83 of a pair of lugs 8l on the trap 55e. From this horizontal position, the bowl is adapted to be tilted upwardly into operative relation to the opening 26 in the thigh section, as the result of continued elevation of the bracket B3 after the tail piece 85 has contacted the bracket 8E.
