Thi invention relates to a vehicle for an. in.--

valid: and more? particularly to. an invalid bed or reclining support. that is mobile, although not necessarily so:limited..

Numerous devices-havebeen manufactured for' usezby invalids including. beds and wheel chairs. However, the use of a bed. and. a wheel chair objectionable in that the invalid has. diiiiculty in moving from one. to the other, oftentimes necessitating assistance in so doing Anobject of this invention is to provide and inclined support that has the characteristics of. the usual invalidbed. and wheel. chair,.

the. bedbeing so arrangedlthatthe invalidmay move the bed. whether lying. flator being in. an inclined position, in that actuating mean have been provided that are. within. easy reach ofthe invalid irrespective. of. his positionin. bed, and.

in addition thereto it has the add'edieatlure, of eliminating the necessity of the use of 1a bedpan, so thatthe invalid may be self-sufficient.

Another. object of this invention is to provide a rest support for an invalid that is economically pro.duced,.that is efiicient, that is easily manipe ulated by the invalid or his attendant and. at the. same time to provide a rest that iscomfortabl'e and convenient".

Other objects and. advantages reside in the construction of parts, the combination thereof" and the mode of operation, as will become more. apparent from the followingdescription.

a. bed.

from. plywoodror a suitable composition mate-- rial, a number of different types of. which may now' be purchased: on the; open market;

Imorder; to; hold the mattress [6. in place sothat: itiwill: not. worlcoif the side over; the angle. bar, a. pair of side boards; IB-are. positioned within. As clearly indicatedin. Figthe side rails I0. uses.- 3; 6- and 7, the mattress. I6 ispreferably made from. sponge. rubber; which: provides. adoquate. resiliency without the useof. a bed spring andwithout. the use. of inner. springs- Furthermore, a, sponge rubber mattress is desirable for an invalid, in that it is more sanitary and. more easily kept clean. than the conventional fabric covered mattress.

As. shown'i-n dotted. position. inFigure l, suitable. mechanism may be provided for; adjusting a portionot thematt-ress into the. inclined position. Ilia so, as to provide an. inclined backrest for the. invalid. In. some; cases, the angle. of in.--

cllnation may approach a vertical position.

The bedis mounted in. spaced relation from the floor by a frameand wheelmechanism, which will. now bedescribed. Two pairs of diagonally disposed angle. iron braces. 20 and. 22, only one pair. of which has. been. shown, are fixedly at tached. to the. under: side. of. the bed and fixedly support. the. bearings 24, only one. or which has been shown. A shaft. 26, functioning as an axle,

is mounted? inlthe. bearings. 24-. A. pair of wheels-- 28 are rotatably mounted on. the. ends of. the shaft 26; so as toprovide asupport adjacent the head of the bed.

Two. pairs of diagonally disposed brackets 30 and 32are secured to the under side of the bed. towards the foot of. the bed. Only one. of these pairs of brackets has. been shown. Members 30. and. 32 support the vertically. disposed bearings.

34, .only one of whichhasbeen shown, used in.

rotatably supporting a shaft. 36 terminating. in. a bifurcatedtor forked end. portion; 38. rotatably supporting acaster wheel there being one of these'wheel's on eachside of the. bed.

"Ifhe wheels 28 are each. providedwith. a hand. I grip rim that may be usedby the invalid when resting in; a prone position to. rotate. or actuate thewlieel 28, to thereby propel the bed. The bed. may-be easily turned, due to theswivel arrangement of the caster wheels 40;. Instead] of using: a pair of caster wheels, one. casterwheel. could. be. mounted, under'thecenter of. the: bed near; the.

foot thereof. This, however,. would result in. a less stable bed, in that-it" would constitute a: tad-- pod support thati's. easily upset.

When. the invalid' lies on his back, it. istpractically impossible. for him..to reach and; manipulate. the. hand. wheels 50,. as may be-clearly seen. In. order to. permit the invalid to move the. bed

with. ease whemherlies on hisi bac'k: or is raised into inclined. position, a pain of. auxiliary hand wheels 60 are used. Each of these hand wheels 50 is mounted upon a stubshaft 62 mounted for rotation in bearings 64 and 66. One end 68 of the stubshaft 62 is square and passes through the hub 10 of a sprocket wheel 12. The ends of the hub 10 are also journalled in the bearings 64 and 66, as clearly shown in Figure 4, so that as the hand wheels 60 and the stubshaft 62 are pulled outwardly, the hand wheels may be removed without removing the sprocket wheel 12. A suitable yieldable lock 13 is used to prevent accidental removal of the stubshafts. 'The sprocket wheel 12 drives a chain 14 passing over a sprocket wheel 16 keyed to the axle 26. There is one of these auxiliary hand wheels on either side of the bed, so that the invalid can easily move the bed around the room or from room to room while lying on his back or while sitting in an inclined position. The auxiliary hand wheels 69 have been removably mounted so that these hand wheels will not provide an obstruction while making the bed, will not be in the way when theinvalid gets out of bed or is put to bed. Furthermore, the auxiliary hand wheels 60 may be removed permanently in the event the invalid is unable to handle the bed or for any other reason it is found desirable to remove the hand wheels.

It is desirable that the bed should be'comparatively short. It may be less than six feet long. Thus, when a short person or a child is using the bed, it can be moved around more easily, requiringless space to turn the bed and obvi ouslv it is much lighter than if the bed were adequately long to meet the requirements of all heights of individuals. 7

In the event the bed is too short for an individual, it may be provided with an extension 80 connected by a pair of supporting bars 82, shown in dotted lines in Figure 2, and seated in suitable sockets provided therefor in the foot of the bed. Any suitable mechanism may be used for looking this extensionin position. Various sizes of extensions may be provided. For example, one extension may be six inches long, another twelve inches, et cetera, so as to meet the requirements of the particular invalid or patient. A substitute extension for the requirements of the individual may be selected from, a group ofvarious lengths.

The use of a bed pan by an invalid presents a problem, especially when the invalid is left alone over a long period of time. This problem has been solved in my disclosure by providing a tubular member 90, extending through an aperture located in a suitable. position in the mattress IS, the tubular member 90 being provided with an outwardly directed flange 92 resting upon the margin of the mattress surrounding the opening therein. Tubular member 90 extends downwardly through the bottom M of the bed.

A rubber collar or sealin gasket 94 substan-- tiallyL-shaped in cross sectional area, is snugly'seated upon the lower end of the tubular member 90 and is duo-functionaLin that it prevents the tubular member 90 from working upwardly through the mattress and it alsoprovides a seal engaging an outwardly directed flange 96 of a urinal can 98 removably mounted. The can 98 is mounted upon a block I provided with a pair of parallel guides I02 and I04. This block I00 is removably mounted in a box I06 provided with a door I08 for opening one end of the box. The block I00 may be provided with suitable handles H0, so that as the door I08 is opened, the block I00 may be pulled out of the box so as to remove the support for the bottom of the can 98, permitting the can to be lowered to permit its removal for emptying, et cetera. The can may be reinserted by placing it in position and then sliding the block I00 back into the box I06, so

v as to provide a support for the can.

Although the preferred embodiment of the device has been described, it will be understood that within the purview of this invention various changes may be made in the form, details, proportion and arrangement of parts, the combinationthereof and mode of operation, which gen erally stated consist in a device capable of carryong out the objects set forth, as disclosed and defined in the appended claim.

Having thus described my invention, I claim:

An invalid bed having a frame, means for supporting a mattress upon said frame, said invalid bed including an axle, a pair of supporting wheels rotatably mounted upon'the ends of the axle, said supporting wheels being rotatably mounted upon the axle so that one wheel may be driven independently of the other, hand grip wheels attached to the sides of the supporting wheels for use by the occupant of the bed, means for supporting the axle under the head of the bed, caster wheel means for supporting the other end of the bed, two pairs of sprocket wheels, a chain interconnecting each pair of the sprocket wheels, one of the sprocket wheels of each pair being attached to the wheels mounted upon the' ends ofthe axle, the other sprocket wheel of each.

pair being mounted in bearings so as to be permanently positioned under the bed, each of said other sprocket wheels having a centrally disposed square aperture, a pair of auxiliary hand grip wheels, a pair of shafts having square portions, each of the auxiliary hand grip wheels being fixedly attached to one of the shafts extending axially in one direction therefrom, the shafts being removably mounted in the square apertures in the sprocket Wheels so that the auxiliary hand grip wheels may be removed by axially sliding the shafts out of the square apertures in the sprocket wheels, the auxiliary hand grip wheels when the square shafts are mounted in the apertures of the sprocket Wheels having a portion located above the level of the mattress to permit the occupant of the bed to move the bed While on his'back by manipulating the auxiliary hand grip wheels, the auxiliary hand grip wheels upon being removed leaving the sides of the bed unobstructed, the occupant of the bed may then move the bed by manipulating the hand grip wheels attached to thesupporting wheels.
