Field of the Invention This invention relates generally to hospital beds and more particularly to a novel hospital bed and associated mattress wherein a central edge portion of the mattress is adapted to be pivoted to a position beneath the bed frame with a bedpan adapted to replace that portion of the mattress for use by the patient in the bed without the patient having to be moved or lifted from the mattress. y
2. Description of the Prior Art The present invention is specifically designed for use with hospital and invalid type bed structures, and specifically concerns itself with the problem of a patient having to dispose of human waste without leaving the bed. While many devices have been provided from time to time for use by such patients in hospitals, the most conventional and common form of container, of course, is the conventional bedpan. However, the placement and removal of bedpans is quite difficult, and in addition, may prove very uncomfortable to the patient. In the use of bedpans, the usual practice is to lift the patient in the region of the buttocks and then place the bedpanl beneath the patient, or alternatively, to roll the patient to one side and then, after placing the bedpan on the mattress, roll the patient back onto the bedpan while at the same time lifting the patient onto the bedpan.
It is to be understood that the use of a bedpan is a time consuming and difficult task that also proves quite uncomfortable to the patient since the bedpan rests directly on the mattress with the patient also being supported and resting upon the mattress.
In view of the difficulties of use of a bedpan, and as in many instances where patients are confined to a bed it is undesirable to move the patient for any reason, and accordingly some prior art structures have been provided in the past for permitting removal of body waste by separation of mattress segments or the like. However, prior to the present invention, the various hospital bed constructions and mattresses contemplated to date in which body waste removal means is provided for use of the patient, have not ,beenV completely successful or practical for one reason or another. Among the reasons and disadvantages for the lack of success of such devices is their impracticality of usage due to the construction thereof; the necessity of the patient having to be moved to some extent in preparing the bedpan for use; the discomfort of the patient during the use of the device; the device being overly complicated and costly; the device being an inconvenience to the nurse or attendant assisting the patient due to difficulties in using the same; and other disadvantages involving lack of patient comfort as well as impracticality of usage.
SUMMARY OF THE INVENTION The present invention remedies and overcomes all of the foregoing deficiencies and disadvantages of presently available hospital and invalid bed structures having means to dispose of human waste associated therewith. The vpresent invention provides a novel hospital bed having a section of the bed frame and mattress pivotally mounted in a manner to be easily and quickly pivoted out of the plane'of the mattress and bed frame to a position disposed beneath the frame without having to move or in any way disturb the patient lying on the mattress, after which a tray is pivoted to a position substantially co-planar with the bed frame beneath the open section of the mattress and is adapted to receive thereon a conventional type bedpan in a position disposed beneath the top surface of the surrounding mattress such that the same may be readily and comfortably'used by a patient on the mattress without having to move or disturb the patient, after which the bedpan is readily removable for cleaning purposes, the tray pivotable to a storage position, and the frame and mattress section pivoted back into position, this all being accomplished in a manner avoiding any lifting or movement of the patient either on the part of the patient or the part of any attendant to the patient.
It is a feature of the present invention to provide a hospital bed and associated mattress wherein a bed pan may be prepared for use and removed after use without any movement or disturbance of the patient.
A further feature of the present invention is the provision of a hospital bed structure and associated mattress having provision for the ready disposal of human waste and which is relatively simple in its construction such that it may be readily manufactured by conventionally known manufacturing methods so as to be provided to hospitals, rest homes and the like at a cost approximately the same as a conventional hospital bed without the human waste disposal feature.
Yet still a further feature of the present invention is the provision of a hospital bed and mattress having means for disposing of human waste associated therewith with such means being easy to use and reliable and efficient in operation.
Other features and advantages of this invention will be apparent during the course of the following description.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings in detail there is illustrated a preferred form of a hospital or invalid bed and mattress constructed in accordance with the principles of the present invention and designated generally in its entirety by the reference numeral l0 and which is comprised of a bed 11 and a mattress 12 which, as will be later described, is adapted to receive a conventional type bedpan, such bedpan being as designated by reference numeral 14.
The bed 11 is of a substantially conventional construction having a headboard 21, a footboard 22, spaced apart supporting legs 23, and a bed frame 24 having a removable section 25 disposed centrally along one edge thereof and pivotally mounted by a hinge 26 for swinging movement about the axis of the hinge from a position co-planar with the remainder of the bed frame 24 and a position disposed beneath and substantially parallel and adjacent to a portion of the bed frame. Section 25 is provided with a locking device 27 which releasably retains the section in the co-planar position with the bed frame 24, release of the locking device permitting the pivotal movement of the section relative to the bed frame.
The mattress 12 is of a conventional construction having a top surface 31 with an elongated rectangular opening 32 disposed centrally thereof along one edge thereof and adapted to be positioned above the pivotable bed frame section 25, such as seen in FIG. 1, with a removable mattress section 33 provided and adapted for pivotable movement with said frame section 25 between a position co-planar with the mattress 31 and a position disposed parallel to and beneath an adjacent portion of the mattress. The mattress section 33 has a bottom surface 34 with the mattress 31 having a bottom section 35, one edge of the bottom surface 34 being hingedly connected to an adjacent edge of bottom surface 35 adjacent an edge of opening 32 by means of a flexible cloth type hinge 36 to permit the swinging pivotal movement of the mattress section 33 with frame section 25.
Pivotally mounted to bed frame 24 at a position adjacent frame section 25 opposite from the hinge member 26 is a tray 37 which is pivotally connected by a pivot rod 38 extending through frame 24 in a manner to pivot relative to the frame between an inoperative position disposed beneath mattress 31 and an operative position disposed beneath mattress opening 32 when the mattress section 33 and bed frame section 25 have been pivoted out of the way. When the tray 37 is in position beneath opening 32, a conventional type bedpan 14 may be rested on the tray with the top edge of the bedpan disposed beneath the top surface of the surrounding mattress 3l such that the bedpan may be used by the patient without the patient having to move or be otherwise disturbed, the patient using the bedpan in comfort thus avoiding any pain to the patient as well as avoiding the need for any labor or excess effort on the part of any attendants who may be attending the patient, such as nurses and the like. The bedpan 14 is rested on and removed from the tray 37 in the direction of arrow 40 in FIG. l.
In operation, locking device 27 is released permitting bed frame section 25 and associated mattress section 33 to pivot to an inoperable position disposed beneath an adjacent portion of the mattress 31 and is secured in such position by any conventional type fastening means, such as latch devices and the like, this inoperable position being as illustrated in FIG. 3. The tray 37 is then pivoted about pivot rod 38 from its inoperative position beneath a portion of the mattress 31 opposite that portion beneath which the frame section 25 is pivoted to, to an operative position beneath mattress opening 32 where it is secured by any conventional fastening means, such as latches and the like. The bedpan 14 may then be slid onto the top surface of the tray 37 to be received in mattress opening 32, such as seen in FIG. 5, with the same being readily positioned for ease of usage by a patient lying on the mattress 3l without the patient having to be moved, lifted or otherwise physically shifted in a manner which may cause pain or discomfort to the patient.
After completion of use of the bedpan, the bedpan 14 is removed from tray 37, the tray 37 is unlatched from its operative position and swung about pivot axis 38 to resume its inoperative storage position, and frame section 25 and mattress section 33 are unlatched from their respective storage positions and are pivoted about pivot axis 26 to resume their normal operative positions with frame section 25 lying co-planar with bed frame 24 and mattress section 33 lying co-planar with mattress 31.
There is thus provided a novel hospital or invalid bed and associated mattress permitting for a patient to dispose of human waste without having to be lifted from the mattress or suffer the discomforts and other embarrassments normally associated with conventional bedpans when used in the conventional manner, the mattress and bed frame permitting for the rapid and easy insertion and removal of a bedpan for use by the patient.
It is to be understood that the form of this invention herewith shown and described is to be taken as a preferred example of the same, and that this invention is not to be limited to the exact arrangement of parts shown in the accompanying drawings or described in this specification as various changes in the details of construction as to shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention, the scope of the novel concepts thereof, or the scope of the sub-joined claims.
