DESCRIPTION OF PREFERRED EMBODIMENTS Referring to FIGS. 1, 2 and 3 showing a preferred embodiment of the invention, there is shown a bed comprising a base frame 1 supported on its legs 3 and having a mat 2 carried thereon. The base frame 1 and the mat 2 lying thereon are formed with a hole 4 for a patients excretion.
The hole 4 is closed by a cover plate 5 provided with a mat 6 having a thickness the same as that of the mat 2. When the cover plate 5 has been raised from a lower position to its normal position, the mat 6 is snugly fitted within the hole 4 so that the upper surfaces of the two mats are in flush with each other to provide a comfortable support for a patient.
According to the invention, when the hole 4 is opened, the periphery of the hole 4 of the mat 2 is deformed by the weight of the patient causing variations in shape and size of the hole 4, however, the mat 6 of the cover plate 5 can be raised into the hole 4, so that the hole 4 of the mat 2 will regain its original shape which makes it comfortable for the patient after an excretion.
A flushing pot 7 is arranged under the base 1, which can be raised into a used position where the upper surface carrying the patients body is in flush with the upper surface of the mat 2 on the base 1 so that the patients buttocks come into closely contact with the pot and are supported thereon to reduce a chance of stain of the mat with the patients excretions.
The cover 5 is supported through a fitting 8 on a guide for vertically guiding the cover 5 and the pot 7 is supported through a fitting 9 in a separate guide for vertically guiding the pot 7 such that the cover plate and the pot are arranged side by side.
In the embodiment illustrated in the drawings, these guides comprise male screws l2, l3 rotatable and threadedly engaged with female screws 10, 11 formed in the fittings 8, 9 and journally supported at their upper and lower ends in a support frame 14. The male screws are driven in normal and reverse directions to raise and lower the fittings for lifting the cover 5 and the pot 7.
The cover 5 and the pot 7 are arranged side by side spaced a determined distance in the support frame 14 with the fittings 8, 9 and the male screws 12, 13. The support frame 14 is movably arranged on rails 15 located on a floor in a room and is horizontally driven by a pinion 17 joumalled in the frame 14, which is driven in normal and reverse directions and in mesh with a rack 16 fixed to the rail in parallel therewith.
The mechanism having a combination of the support frame 14, the rack 16 and the pinion 17 serves to connect the lifting guide for the fitting 8, that is, the male screw 12 in the embodiment with a mechanism for horizontally moving the cover 5 from a position corresponding to the center 0 of the hole 4 to a position P spaced threfrom and to connect the lifting guide for the pot 7, that is, the male screw 13 with a mechanism for horizontally moving the pot 7 from a position Q to the position corresponding to the center 0 of the hole. Furthermore, the mechanism having the combination ensures that the base for the horizontally moving mechanisms, i.e. the rails 15 are positively arranged relative to the bed.
The male screws 12, 13 and the pinion 17 are driven in normal and reverse directions by means of motors 18, 19 and 20 fixed to the frame 14, respectively.
In the embodiment, there are provided with a pump motor 21 for flushing and injection of cleaning water against the patients excretory organ after excretion, a fan motor 22 for ventilation and warm wind injection for drying the organ after cleaned and a tank 23 for cleaning water, these motors being fixed to the support frame 14. However, these motors may be arranged on the floor in the room.
It can be understood that it is required to operate these motors 18, 19, 20, 21 and 22 automatically in a determined sequence.
The vertically and horizontally moving mechanisms for the cover and the pot according to the invention have advantages in that the cover and the pot can be in powered synchronism with each other to facilitate an automatic control of the bed.
Referring now in particular to FIG. 7, the male screws 12, 13 are driven through worms and worm gears by traverse shafts 24, 25 which are joumalled in parallel with each other at the bottom of the frame 14 and rotatably driven by the motors 18, 19. The pinion 17 in mesh with the rack 16 is keyed to the lower end of a vertical shaft 26 rotatably driven by the motor 20 and joumalled in the frame 14 as shown in FIGS. 7 and 10.
The pump motor 21 and the fan motor 22 may be arranged in a unit in the frame 14 as shown in FIGS. 7, 9 and 11. Accordingly, the vertically and horizontally moving synchronizing mechanisms and the flushing, drying and ventilation devices are all compactly housed in a relatively small space within the support frame 14.
FIG. 14 illustrates an example of a circuit for an automatic control for the above motors. The circuit includes a drum switch 27 of which segments are shown in development which rotate in a direction of an arrow for controlling the normal and reverse rotations and stops of the motors 18, 19 and 20. Contacts 28-33 are connected, in series with a line between a power source 4 short-circuit only upon starting the motors in normal or reverse direction.
Referring to FIG. 14, a starting switch 44 is a timing switch which opens when a determined period of time for closing has elapsed. When the switch 44 is closed, a motor 45 for the drum is energized to rotate the drum 27 so that a segment 35 causes the cover to lower until the cover reaches its lowermost position (FIG. 4) where the contact 29 is opened to stop the motor 18. Then, a segment 36 causes the frame 14 to move the left-hand side as viewed in FIG. 5 until it reaches its stroke end as shown in FIG. 5 when the contact 31 is opened to stop the motor 20. Then, a segment 37 causes the pot 7 to raise until it reaches its uppermost position where the motor 19 is stopped. At the moment a segment 41 energizes a timer motor 42 to rotate a switch drum 43 so that its segment 46 opens a circuit for the drum motor 45 to stop the drum switch 27. In this condition, all the motors 18, 19 and 20 stop so that the pot is ready to be used by the patient. The switch drum 43 for the timer continues its rotation during the use of the pot. When a determined period of time has elapsed or the patients excretion has completed, a segment 47 energizes the pump motor 21 to effect cleaning and flushing so that the patients excretion in the pot 7 is exhausted together with the flushed water through a flexible conduit 58 into an excretion reservoir 59 or a drainpipe (not shown). When a segment 47 is brought into contact with a contact as the drum 43 rotates, the pump motor 21 is stopped and a segment 48 energizes a fan motor 32 shown in FIG. 13 and simultaneously supplies current to a heater 52 arranged in a blast pipe 51 to provide a warm wind into the pot for drying the patients excretory organ and its proximity. When a segment 53 excites a solenoid 54, a rack 55 moves to the left-hand side as viewed in FIG. 13 to rotate apinion 56 so that a valve member of a valve 57 is rotated as in phantom lines in FIG. 13 to connect the blast pipe 51 to the suction side of the fan and simultaneously to disconnect the circuit for the heater, with the result that an offensive smell within a hood covering the patient on the bed is positively exhausted through the pot, the valve 57 and the flexible conduit 62 to atmosphere 60. After a determined period of time a passage of the segment 48 on a contact causes the fan motor 32 to stop and the solenoid 54 to be deenergized so that the rack 55 is moved to the right-hand side as viewed in FIG. 13 by the force of a tension spring 61 to return the valve 57 to its original position as shown in full lines in FIG. 13. When the segment 46 again energizes the drum motor 45, its segment 41 opens the circuit for the timer motor 42 to stop it.
After that the segments 38, 39 and 40 cause in succession the motors 19, 18 and 20 to energize in reverse directions, so that the pot 7 and the cover 5 return to their positions as shown in FIG. 3. At this time the starting switch 44 is in open position so that the contact 28 adapted to operate at the uppermost position of the cover is actuated to cut off the power source.
The control device above described is mounted on the support frame 14 and is connected by a flexible cord to the power source. The starting switch 44 is controlled by a remote control system.
Though the lifting mechanism for the cover plate and the pot is shown utilizing the movement of a female screw threadedly engaged with a rotating screw and the horizontally moving mechanism is shown utilizing the movement of a shaft of a pinion in mesh with a fixed rack in the embodiment, any other means may be used for the mechanisms, for example, a combination of links and levers, hydraulic cylinders or the like.
The bed according to the invention has various advantages in that a patient can easily excrete on a thick mat on the bed by himself without staining the mat with his excretion without requiring any help of a nurse thereby reducing her labor and making it possible for the patient to lay himself on a comfortable thick mat. Notwithstanding the thick mat, according to the invention the mechanism for opening and closing the hole of the bed for his excretion and moving the pot is simple in construction and can be automatized with case, so that the bed according to the invention can be produced in a mass-production with a great industrial advantage.
It is understood by those skilled in the art that the foregoing description is a preferred embodiment of the disclosed bed and that various changes and modifications may be made in the invention without departing from the spirit and scope thereof.
