11 Claims. (Cl. 4-10) An object of this invention is to provide an improved commode wherein the flushing of the bowl thereof is coordinated with the lowering of the odor trap in the discharge line from said bowl, whereby, flushing can .be effected with a low flushing liquid pressure andwit-h a minimum amount of flushing liquid for each flushing .of

the bowl.

An important object of this invention is to provide an improved commode which is of substantially bed-height .So that the commode can be positioned alongside a bed to receive a bedridden patient without substantially changing the reclined position of the patient during the transfer to and from the commode, said commode having a toilet bowl with a discharge line therefrom extending into a Waste tank, the discharge line being adapted to be lowered below the bottom of the bowl during flushing whereby the flushing liquid does not have to rise in the bowl to initiate siphoning action for discharge from the bowl as is necessary in the conventional odor-trap toilet bowls, thereby enabling the use of a much shallower bowl and a great saving in space which permits the bed-height commode to be adequately flushed and at the same time to be spaced sufficiently high above the conventional stationary commodes in homes or hospitals so that the waste tank can collect the waste from a number of fiushings of said bowl and thereafter be positioned over such a stationary commode for draining thereinto.

Another object of this invention is to provide an improved commode Which is adapted to receive :a patient or user thereof in a reclined position and which has a back rest with a flushing liquid supply tank connected thereto, whereby the patient may be raised to a sitting position while simultaneously elevating said tank so as to provide an increased flushing liquid pressure for the commode.

Another object of this invention is to provide an improved commode adapted to be disposed alongside a bed, such as a hospital bed, and constructed so that a patient or user can be transferred thereto and supported thereby with his legs substantially horizontal and his head and back reclined and so that thereafter the patient or user can be placed in a sitting position thereon with his legs, back and head supported.

Still another object of this invention is to provide a portable commode having a flushing liquid tank pivoted thereto for raising to an elevated position to increase the gravity flow therefrom to the commode bowl for flushing same.

The construction designed to carry out the invention will be hereinafter described together with other features thereof.

Figure 9 is a view similar .to Figure 8, but illustrating the .raised position of the backrest and tank :duringfl-ushing of the bowl of the commode; and

Figure 10 is an isometric view of the form of the flushing valve and odor trap construction utilized in the portable commode of Figures 8 and. 9.

In the drawings, the letter S designates the suppor or housing of the commode of this invention. The support ,S has a toilet bowl 10 and a toilet seat 11 mounted at its upper end, with the toilet seat v11 being disposed over the bowl 10. Flushing liquid, suchas water, is supplied under pressure from some source, such as an elevated tank, through an inlet line 12 to the upper end of the toilet bowl 10 and below the seat 11. The admission of the flushing liquid to the bowl 10.is controlled by a valve V which is constructed so as to normally be urged to a closed position. The lower end of the toilet bowl 10 has a discharge line 14 connected thereto which is constructed so as to serve as an odor trap when in a raised position and to permit the discharge of liquid from the bowl 10 when in a lowered or straight position. As will be explained, the valve V and the discharge line 14 are constructed so that .the discharge line 14 is raised as an odor trap when the valve V is closed, but upon opening the valve V, the discharge line 14 is lowered to provide for the discharge of the liquid from the bowl 10 without requiring the liquid to overcome the back pressure of the odor trap.

Referring now to Figures 1 and 6 in particular, therein it can be seen that the support or housing S is tubular and is disposed on the floor F or any suitable base. The upper end of the support S has mounted thereon the radial flange 16 of the bowl 10, which flange 16 may merely rest upon the support S or may be atlixed thereto by a suitable securing means such as an adhesive or bolts (not shown). Below the radial flange 16, an annular shoulder 17 is formed on the bowl 10, with an opening 17b being formed in the wall 17a of the bowl 10 above the annular shoulder or ledge 17, for the reception of a rigid connec: tor tube 12a of the inlet line 12. The toilet seat 11 is mounted on the bowl 10 in contact with the radial flange 16, with the seat 11 being secured to the bowl 10 by an ad;

. 3 hesive if the bowl 10 and seat 11 are of plastic or similar material, or by solder or other securing means if the seat 11 and bowl 10 are of metal or an equivalent material. It is preferable to form the seat and bowl of plastic materials with a bond at the flange 16 so that the seat 11 and bowl 10 form a unitary structure.

The seat 11 has an inner downwardly extending rim 18 which extends below the annular shoulder or ledge 17 of the bowl 10. The rim 18 has an enlargement 18a which contacts the wall of the bowl 10 below the shoulder 17 to form a closed annular pocket 20 at the upper end of the bowl 10. The enlargement 18a has openings 18b spaced uniformly around the periphery of the enlargement 18a so that the flushing liquid which is admitted through the opening 17b into the annular pocket 20 is uniformly distributed along the inner surfaces of the bowl 10 to wash and thereby flush the bowl upon the admission of the flushing liquid.

The bowl 10, below the flange 17 is generally cupshaped with an outlet tube 22 connected at its lower end and extending in a substantially horizontal direction, which provides for the connection of the flexible discharge line 14 thereto. The discharge line 14 is made of rubber or a rubber-like material which is secured to the outlet 22 by its own elasticity or resilience, or by adhesive or any equivalent securing means.

Liquid, such as water, under pressure is supplied to the end 12b of the liquid inlet 12 which is on the side of the valve V remote from the inlet 12a. This end 12b may be connected to a tank having the flushing liquid therein with the pressure for the liquid being supplied by gravity or the connection may be to an ordinary water tap or faucet so that the usual pressure in a building is utilized. The valve V which controls the admission of the liquid into the bowl 10 through the line 12 is of a conventional construction and may be of the spring loaded type which is adapted to stay in a closed position by the spring action therein. The details of the valve V are not illustrated since such details are well known and any conventional type of spring loaded or weight actuated valve may be utilized. However, in Figures 3 and 5, a spring 25 is shown as having a connection to a fixed base 26 in order to illustrate the action of the spring, which is normally within the valve V. This spring 25 urges the handle 26 of the valve V upwardly to a closed position, although it will be appreciated that in some instances the spring loaded valves have the handle 26 extending substantially horizontal when the valve is closed. To open the valve V, for the admission of the flushing liquid from the flushing liquid source, it is only necessary to force downwardly on the handle 26 whereupon a flushing liquid is admitted into the annular pocket 20 of the bowl 10 to wash the inner surfaces of the bowl and flush same. The handle 26 has a link or lever 27 connected thereto at a pivot 28 for engagement of a hooked end 29 in a loop 30 on a rigid ring or tube 31 encircling the discharge line 14 at a point a suflicient'distance from the outlet 22 to provide an arch in the discharge line when it is in a raised position (Figure 2).

By reason of the linkage 27 connecting the handle 26 and the discharge line 14, the discharge line 14 is held in its raised position to form an odor trap by the same spring which maintains the valve V closed (spring 25 in Figure 3). When the handle 26 is lowered as shown in Figure to open the valve V, the discharge line is simultaneously lowered to form a straight substantially horizontal outlet line (Figure 4) so that the flushing force does not have to overcome any back pressure or elevation which would be required if the discharge line were in position as shown in Figure 2 to serve as an odor trap. The outlet line 14 may, of course, be lowered below a straight horizontal position to assure flow of liquid and waste from the bottom of the bowl 10.

In the operation or use of the commode illustrated in Figures1-6, the flushing liquid such as water is supplied under pressure from some source (not shown) to the inlet line 12 and the admission of such flushing liquid is controlled by the valve V. Considering that a person has just used the commode of this invention, the valve V is opened by forcing downwardly on the handle 26 against the action of the spring 25, or its equivalent, to simultaneously lower the discharge line 14 from its position shown in Figure 2 wherein it serves as an odor trap to its position shown in Figure 4. Thus, while the flushing liquid is being admitted to the bowl 10 for fiushing same, the discharge line 14 is substantially straight, that is, it is on substantially the same horizontal level as the outlet 22 at the lower end of the bowl 10, or below such horizontal level if desired, so that the discharge of waste and liquid from the bowl 10 is not impeded by the arched position of the discharge line 14 when it is used as an odor trap. It will therefore be evident that the maximum flushing can be obtained by reason of this construction. After the flushing has continued sufficiently long in order to wash all waste material from the bowl 10, the valve V is closed and the discharge line 14 is simultaneously raised to its arched position shown in Figure 2 whereby a portion of the flushing liquid L is trapped in the bottom of the bowl 10 so that any odors from the tank (not shown) to which the discharge line is connected will not escape through the discharge line and out through the bowl into the room wherein the commode is used.

In the form of the invention shown in Figure 7, a flushing liquid tank T is shown disposed behind the toilet seat 11 and the support S. In this construction, the handle 26 on the valve V is disposed outside of the tank T and has a spring 25 connected thereto with the other end of the spring being fixed to the tank. The handle 26 extends into the interior of the tank T where it is connected to a conical valve member 35 by a suitable pivoted linkage 36. The valve member 35 fits into a discharge opening connected to the end 12b of the discharge line 12, whereby the flow of the flushing liquid from the tank T can be controlled. Except for the modified form of the valve V shown in Figure 7, the construction and operation is identical with that shown in Figures 1-6.

In Figures 8-10, the valve and odor trap construction illustrated in Figures l-6 is shown as used in a portable commode, with the valve and odor trap construction being modified as will appear hereinafter. In this use, the support S is a housing of substantially rectangular construction which is mounted on a frame 37 with wheels 38 for enabling the movement of the commode to a position alongside a bed, such as a hospital bed. The toilet bowl 10 and the toilet seat 11 are constructed in substantially the same manner as that illustrated in Figures l-6, with the bowl and seat being mounted at the forward end of the support S of the commode (Figure 9). In this form of the invention, the commode has a back-rest 39 to which is connected the flushing liquid supply tank T. The back-rest 39 and the tank T are pivoted at the pivot rod 40 on the forward end of the back-rest 39 adjacent the seat 11, with the pivot rod 40 extending through the support S or brackets mounted therein in any suitable manner.

In this form of the invention, the inlet line 12 is substantially the same as that shown in Figures l-6, although in this form the line 12 must be elastic or flexible so as to prevent damage thereto when the tank T is raised and lowered. The inlet line 12 is connected with the valve V and extends into the annular pocket 20 in the same manner as previously described with the valve V being mounted on the bowl 10. Thus the flushing liquid which is supplied to the bowl 10 is fed from the tank T through the inlet line 12 to the annular pocket 20. The valve V in the form of the invention shown in the Fig ures 8-10 is identical with that shown in Figures 1-6,v except that it is weight loaded for maintaining the same closed normally and is adapted to be opened by a down ward movement of the handle '26, as will be explained. The discharge line 14 may be flexible as in Figures 1-6, but preferably is a rigid elbow or return bend which has a flexible or elastic end 42 connected to the outlet 22 of the bowl This flexible end connection 42 is preferably a rubber sleeve which is joined to the rigid elbow 14 and to the outlet 22 and becomes corrugated when in the raised position (Figure 8). The open end of the elbow 14 extends into a waste tank W and a flexible seal 43 is provided around the elbow 14 to prevent leakage of the liquid and vapors which pass into the waste tank from the elbow 14. As shown in the drawings, the handle 26 is connected to a rod or bar 26a which extends to the valve V. The elbow 14 is connected to the bar 26a and thus to the handle 26 by a linkage which includes an upper link 44 and a lower link 45, which are pivotally connected to a weight arm 47. The arm 47 is pivoted on a rod 48 to the support S and a weight 46 is mounted on the arm 47 on the side of the pivot 48 opposite from the side at which As pointed out above, the back-rest 39 and the tank T l are adapted to be raised together, with the back-rest 39 serving as a support for the back of the person using the commode when such person is in a sitting position. When the user or patient is to be. transferred to the commode, the back-rest 39 is in a reclined position as seen in Figure 8, which is at an angle slightly above the horizontal position of the seat 11. This angle is used because the commode is particularly adapted to be used alongside a hospital bed wherein the head end of such bed can be inclined at substantially the same angle as the back-rest 39 (Figure 8). It is therefore possible to move a patient from the hospital bed to the commode without changing his reclined position. Additionally, a leg rest 48 is provided on the forward end of the support S and is pivoted at 49 so that it can extend in substantially the same horizontal plane as the seat 11 (Figure 9). The leg-rest 48 is maintained in such horizontal position by a rod 50 pivoted at its lower end to the support S at 51; the upper end of the rod 50 has a lateral projection slidable in a wire bracket 53 on the lower surface of the leg-rest 48. When the rod 50 is supporting the leg-rest 48, the upper end fits within a notch 53a as shown in full lines in Figure 9, and upon lowering the leg rest 48, the rod 50 pivots rearwardly to the dotted line position shown in Figure 8. Of course, any suitable or equivalent means for maintaining the leg rest in its horizontal position could be used.

When it is desired to place the patient or user on the commode, therefore, the patient can be transferred to the commode surface which is substantially in the same reclined position as that presented by the top surface of the hospital bed. After the patient or user has been placed on the commode, then a foot rest 55 below the support or housing S can be moved from its retracted position within the shelf 56 as shown in Figure 8 to its extended position shown in Figure 9 wherein it is horizontally disposed for receiving the feet of the user when in a sitting position. The leg rest 48 of course will be lowered by pivoting the rod 50 rearwardly and permitting the rest 48 to pivot downwardly on its pivot 49 to the position shown in Figure 8. The back rest is also pivoted upwardly to the position shown in Figure 9 to provide support for the back of the user when in such sitting position.

The mechanism for raising the back rest 39 and attached tank T is preferably a crank mechanism M which includes a threaded sleeve 57 connected to a crank handle 58 which is mounted in the support S for rotating the sleeve 57 upon cranking the handle 58'. Within the sleeve '57 is a threaded shaft 59 which is movable inwardly and outwardly of the threaded sleeve 57 upon rotation thereof. The outer end of the shaft 59 is connected to a connector plate 60 by a pin 61 in a slot 62 of the plate 60. The upper end of the plate 60 is welded, keyed or otherwise affixed to the pivot rod 48 so that upon rotation of the sleeve 57 and forward movement of the shaft 59 by turning the crank 58, the plate 60 moves forwardly to pivot the rod 40 which carries the back rest 39 and tank T downwardly until the back rest 39 contacts the upper edge of the support S (Figure 8). Upon a reverse turning of the crank 58, the shaft 59 and the plate 60 are moved rearwardly to pivot the rod 40 so as to raise the back rest 39 and tank T (Figure 9).

A particular advantage to having a tank T which is raised is due to the fact that the pressure or head of liquid in the tank is thereby increased when the device is used, and it is necessary to flush the bowl 10. On the other hand, the tank T is lowered out of the way of the person being positioned on the commode and also is out of the way when the commode is not being used. It will be appreciated, of course, that the back rest 39 could pivot downwardly to a substantially horizontal position if the support S were so constructed, since the support S is the limit which determines how far back the back rest 39 can move. In some cases, therefore, it may be desirable to have a back rest 39 at substantially the same elevation as the toilet seat 11.

For supporting the arms of a patient while on the commode, the arm rest which is pivoted to the housing or support S is provided; stops 76 and 77 are on the housing S to limit forward and rearward movement, respectively.

A waste tank W is mounted in the support S at an angle so that a discharge opening 66 in the bottom thereof is at substantially the lowest point of the tank W. A discharge valve 67 having an elongate rod 68 extending upwardly therefrom is adapted to seat in said opening 66 to. close same. A spring 69 acts to urge said valve 67 upwardly to hold the valve 67 above the opening 66 whereby liquid and waste will readily drain from the tank W. The rod 68 extends through a sleeve 70 secured to the top of the Waste tank and the lower end of the spring 69 rests on the top of said sleeve 70 with the upper end of the spring being confined by a handle 71. The valve 67 is maintained seated in opening 66 by transverse pins 72 on the rod 68 which are locked below the lower edge of the sleeve 70. Upon a rotation of the handle 71 and rod 8, the pins 72 are aligned with longitudinal slots 73 in the sleeve 70 so that the spring 69 lifts the valve 67 upwardly until the pins 72 hit the top of the slots 73, thus opening the valve to discharge waste from the tank W. The contents of the waste tank W will be discharged through the opening 66 preferably into a fixed or stationary commode K of the usual construction in a home or hospital.

In some cases it may be desirable to provide a vapor vent in the top of the waste tank W with an inner tube 63 affixed to the tank and a detachable sleeve 65 slidably disposed therearound (Figure 9). The sleeve 65 preferably has a screen 64 therein which rests on the upper edge of the inner tube 63 whereby a chemically treated filter may be supported to mask or remove odors from the outgoing vapors. The sleeve 65 and attached screen 64 may be removed for insertion of a spray hose into the opening 63 to wash down the tank W.

In the operation or use of the device shown in Figures 8-10, as has been explained, the patient or user is placed on the commode with the back rest in the reclined position shown in Figure 8 and the leg rest 48 extended substantially horizontally (Figure 9). Thereafter the leg rest 48 is dropped to its lowered position (Figure 8) and 'the foot rest 55 is pulled from its shelf 56 below the body or housing S to provide the foot rest. Substantially simultaneously with the positioning of the patients feet on the foot rest 55, the arm rest or handle 57 and the back rest can be pivoted forward to the position shown in Figure 9, so that the patient will be fully supported in a sitting position. After the patient has used the commode, he can actuate the valve V by moving the handle 26 downwardly to open the valve V and allow the flushing liquid to discharge into the bowl 10 and also to lower the trap or line 14. When the handle 26 is released, the weight 46 will return the valve V to a closed position and will simultaneously raise the elbow or discharge line 14 so as to form an odor trap with a portion of the flushing liquid trapped in the bowl 10. Then the arm rest 75 and the back rest 39 may each be moved to their original lowered positions shown in Figure 8, and the patient can be placed back on the bed. When the commode has been used a sufiicient number of times to substantially fill the waste tank W, the valve 67 can be opened with the commode placed over a fixed receptacle such as the usual hospital or home commode K so as to empty same.

From the foregoing it can be seen that a portable commode of bed-height has been provided which has a waste tank sufiiciently high from the floor to permit discharge of the waste from the waste tank into a conventional stationary commode. This is accomplished primarily because of the coordinated lowering of the odor trap and the opening of the flushing valve, because this permits proper flushing without requiring the excess of water necessary in the usual stationary commode to begin the siphoning action from the bowl. As is well known, the usual stationary commode requires the flushing water to rise considerably in the bowl before the siphoning action of the water occurs. Such an excess of water would not be practical in a portable commode since the size of the flushing water and waste tanks would have to be too large or the waste tank would have to be emptied too frequently. In addition, the commode of this invention does not sacrifice the odor trap. Other advantages have been set forth above.

The foregoing disclosure and description of the invention is illustrative and explanatory thereof and various changes in the size, shape and materials, as well as in the details of the illustrated construction may be made, within the scope of the appended claims, without departing from the spirit of the invention.
