the bed of the present invention comprises the underlay 1 , on top of which the patient is arranged to lie ; a support frame 2 , which comprises an essentially horizontal support member 2a , and an essentially vertical support member 2b , which horizontal support member 2a is arranged above the underlay ; and suspension means 3 , such as straps , whereby the underlay 1 is suspended from the horizontal support member 2a . the support frame 2 is attached to the structures of the premises , for instance to the wall 5 , as is illustrated in fig1 . in this case the support frame 2 is fastened to the wall with fastening means , such as studs 5 , at the vertical support member 2b . the support member 2a is formed of an at least roughly horizontal , elongate bar , the first end whereof is free and the second end whereof is connected to the vertical support member 2b , which also is formed of an elongate bar . the support members 2a and 2b can be interconnected in an arched or angular fashion . in the embodiments of fig1 and 3 , the horizontal support member 2a of the support frame 2 is provided with a continuation 6 . this is fitted at least partly inside the support member 2a , and can be pulled out to form a continuation for the support member 2a when the need arises to lengthen the support member 2a . thus the distance of the suspending means 3 from each other can be lengthened , so that there can be used a long underlay 1 , or shortened , so that a short underlay 1 is used , depending on the length of the patient . in connection with the support member 2a there is provided a crossbar 4 . the arms 4a , 4b of the crossbar 4 are placed at an angle , advantageously 90 °, with respect to the support member 2a . the suspension means 3 , which in the following are generally called straps , can be formed of members of a given length , which members are flexible and bendable but maintain their length . the underlay 1 is fastened , by means of the straps 3 , to the support member 2a of the support frame 2 , above the underlay 1 , at least when the bed is being used . the support points c , d , e of the straps 3 in the support frame 2 , i . e . in the support member 2a and the connected crossbar 4 and continuation 6 , are located at intervals from each other . at least one for instance c , of the support points is located outside the line drawn via the other support points d , e . thus the underlay 1 is supported against the support frame at three points c , d , e falling on the apices of a triangle , preferably an equilateral triangle . in that case the patient p lies in the bed in a stabile fashion , in the support of the support frame 2 . the said fastening points c , d are in fig3 located at the ends of the arms 4a , 4b of the crossbar 4 , wherefrom the arms 4a , 4b are connected , by means of the straps 3 , to the sides of the underlay 1 , on both sides of the top part of the patient &# 39 ; s body . in fig3 the third support point e

feet . the free end of the support member 2a , or the continuation 6 connected thereto , can also be provided with another crossbar 7 which in structure corresponds to the crossbar 4 . this second crossbar is illustrated with dotted lines in fig1 and 3 . thus for instance the foot of the patient &# 39 ; s bed can be lifted in similar fashion as the head . it is , however , maintained that in most cases the attaching of the fastening members directly to the support member 2a ( or continuation 6 ) is a fully satisfactory measure , and the patient can rest in a perfectly safe and stabile fashion in an underlay thus suspended . in the embodiments of fig2 and 3 , the bed comprises a hauling apparatus 8 . it is connected to the vertical support member 2b . thereby the vertical support member 2b can be raised and lowered , so that simultaneously the horizontal support member 2a and the underlay 3 suspended thereto rise or descend . the hauling apparatus 8 can be realized with a gear rack and gear wheel combination , where the gear rack is arranged in connection with the support member 2b . the gear wheel can be rotated with a suitable power means such as a hand crank or an electric motor . alternatively the hauling apparatus can also be realized with a fluid cylinder , whereto the fluid is fed by means of a hand pump or suitable actuator , such as a pump operated with an electric motor . the hauling apparatus 8 is connected to the fastening means 9 , such as a flange , whereby the support frame 2 of the bed is fastened to the wall s of the premises by means of studs 5 or other corresponding fastening means . the support frame 2 of the bed is attached , at the vertical support member 2b and turnably around the axis b -- b , to the hauling apparatus 8 . the support frame 2 , particularly the horizontal support member 2a , can thus be turned at a predetermined angle α from the basic position , which is perpendicular to the wall structure s , to either side thereof . the support frame 2 can be locked in a desired position . in fig4 and 5 , there is illustrated a third bed according to the invention . the support member 2a of the support frame 2 is

. the straps 3 are arranged , according to fig6 on rollers 21 . these rollers 21 are placed in the crossbar 16 , in the vicinity of the fastening point of the support member 2a , parallel to the support member and at the same time to the lengthwise axis a -- a of the underlay 1 . at the ends 16a , 16b of the arms of the crossbar 16 , there are installed folding wheels 22 , wherethrough the straps 3 are arranged to pass , as is seen from fig6 . in the vicinity of the free end of the support member 2a of the support frame 2 , there is arranged a second set of rollers 23 on both sides of the support member 2a , so that the axes thereof are parallel to the lengthwise axis a -- a of the support member . the second set of rollers 23 is provided with straps 3 in similar fashion as the first set 21 . the rollers 21 , 23 are advantageously charged with springs so that the straps are in their rest position wound on the rollers 21 , 23 . from the rollers 21 , 23 the straps can be pulled down from the crossbar 16 or from the support member 2a , and fastened to the underlay 1 by means of clasps 24 or other such fastening means . the straps 3 arranged on the rollers 21 , 23 are of defined lengths . the lengths of the straps are such that the underlay 1 complete with the patient p rests at a suitable height from the floor , for instance 60 . . . 70 cm . alternatively the rollers 21 , 23 can be provided with locking members in order to prevent winding or lengthening of the strap after the desired height of the underlay has been set . the patient is placed in the bed of the present invention as follows . a transport couch is used as an aid in the process . the underlay 1 is arranged on top of the transport couch for the patient , whereafter the patient is lifted on top of the underlay 1 and the transport couch . the patient is transported on the couch to beside the bed of the invention , to underneath the horizontal support member 2a of the support frame 2 . thereafter the straps 3 are pulled down from the rollers 21 , 23 , and fastened at the sides of the underlay 1 , in the vicinity of both ends thereof , on the left and right sides of the patient . thereafter the transport couch is lowered , until the underlay 1 complete with the patient p rests freely from the straps 3 in the support of the support frame 2 . now the transport couch can be removed . if the bed of the invention is provided with a hauling apparatus 8 as in fig2 and 3 , the height of the transport couch does not necessarily have to be adjustable . in that case the hauling apparatus 8 is utilized while shifting the patient onto the underlay , to be supported by the support member 21 by means of the straps 3 . the support frame 2 of the bed of the invention can be detachably fastened to the structures of the premises , for instance to the wall . on the other hand , the support frame can be detachably fastened to a suitable transport couch , for example the transport couch of the patient . one such arrangement is illustrated in fig7 and 8 . the support frame 2 is provided with fastening means 25 and the structures of the premises , for instance the wall s of the patient room , is provided with a first socket member 26 and the transport couch 28 with a second socket member 27 . the first socket member 26 is formed of a plate - like housing 29 provided with a number of brackets such as pins 30 , and the first set of locking members 31 . these locking members include at least two lock bolts 31a or similar members , which are fastened so that they can be moved in a direction parallel to the surface of the housing 29 . the vertical support member 2b of the support frame 2 is provided with fastening means 25 including a fastening flange 32 with holes 33 for the pins 30 of the first socket member 26 , and a first set of nests 34a for the lock bolts 31a or corresponding members of the locking members 31 of the first socket member . the fastening members 25 also include a second set of nests 34b for the second set of locking members 38 . the fastening flange 32 also is provided with a second set of brackets , such as pins 35 . the second socket member 27 of the transport couch 28 is provided with a recess 36 for the vertical support member 2b of the support frame 2 and for the tubular member 10 , with apertures 37 whereto the second set of pins 35 of the fastening members 25 can be fitted , and further a second set of locking members 38 , which are advantageously similar as the first set of locking members 31 . the lock bolts 38a of the second set of locking members 38 can be locked to the second set of nests 34b provided in connection with the fastening members 25 . the locking members 31 , 38 and nests 34a , 34b provided in the fastening members 25 and socket members 26 , 27 together form two sets of fast coupling means , whereby the support frame 2 can be easily attached to the wall structure and detached therefrom , and respectively the support frame 2 can be easily attached to the transport couch 28 and detached therefrom . the coupling of the support frame 2 on one hand to the wall s of the premises , and on the other hand to the transport couch 28 , takes place as follows . in fig7 the support frame 2 is attached to the wall s . the holes 33 of the fastening flange 32 of the fastening members 25 are fitted to the first set of pins 30 of the firs socket member , and the bolts 31a of the locking members 31 of the socket member are inserted to the nests 34a of the fastening flange 32 . when the support frame 2 is desired to be attached to the transport couch 28 , it is moved so that first comes the end provided with the recess 36 , to against the vertical support member 26 of the support frame 2 and the tubular member 10 , so that the pins 35 provided in the fastening flange 32 match the apertures 37 of the transport couch 28 . thereafter the bolts 38a of the locking members 38 of the transport couch 28 are shifted and locked in the nests 34b of the fastening flange 32 , so that the transport couch 28 is coupled to the fastening members 25 . thereafter the bolts 31a of the locking members 31 of the first socket member 26 are released and pulled out of the nests 34a of the fastening flange 32 , so that the fastening flange 32 can be drawn , together with the transport couch 28 , apart from the pins 30 of the socket member 26 . now the support frame 2 is attached to the end of the transport couch 28 with fastening members . in a corresponding fashion but opposite order , the support frame 2 together with fastening members 25 can be reattached either to the same socket member 26 or to a similar socket member 26 in other premises . fig9 and 10 show a schematical illustration of an underlay 1 . in width and length this underlay corresponds at least roughly to a normal bed . the underlay 1 comprises the bed bottom 40 and the frame 41 . the bottom 40 is formed of some flexible , advantageously thin material , which , however , carries even a heavy patient well . the frame 41 is formed of support rails 42 , which are fitted on all sides of the bottom 40 . along the sides of the bottom 40 , there are formed tubular passages , where the support rails 42 are inserted and then connected to each other . in order to fasten the clasps 24 of the straps 3 , there are provided apertures 43 on the sides of the bottom 40 . now the clasps 24 are easily inserted through the apertures 43 and fastened to the support rails 42 . the bottom 40 of the underlay 1 can be made of many different materials , such as cloth or net . fig1 illustrates an underlay 1 , the bottom 40 whereof is made of net . the bottom is most advantageously made of some such material that can be left under the patient when the patient is put on the transport couch and taken for instance to the examination rooms of the hospital . thus the shift from the transport couch back to the suport of the support frame 2 naturally becomes easier , because the underlay 1 is continuously under the patient . the bottom 40 can be made for example of some waterproof material such as plastic . the bottom 40 is provided with an aperture 44 , which is most advantageously placed in the middle region of the underlay . to this aperture 44 , there can be connected a hose 45 for instance by means of a suitable bayonet catch 46 . the hose 45 can be conducted from the aperture 44 of the underlay further to a sewer or other vessel where water can be collected . this type of underlay 1 is suitable to be used as a shower basin , where the patient can be conveniently washed . the bottom 40 of the underlay 1 can be made of two different parts , as is shown in fig1 . the first bottom part 40a is made of net or other such material , which is well permeable to air and water . the second part 40b is made of some waterproof material , such as plastic foil . the second part 40b is arranged on a roller 47 along the long side of the underlay 1 , wherefrom it can be drawn to underneath the first part 40a . the second bottom part 40b can be attached , with suitable fastening means , to the frame 41 of the underlay 1 . the second part 40b is used when the patient is washed for instance by means of a shower . when the second part 40b is not needed , it is rolled along the long side of the bed bottom 40 . this second bottom part can naturally be provided with a corresponding aperture 44 , whereto a hose can be fastened by means of a suitable catch , in similar fashion as was explained in connection with the underlay 1 of fig9 and 10 . it is advantageous to provide the bottom 40 of the underlay 1 with an aperture 48 for a bedpan ( marked with dotted lines in fig9 and 10 ). this aperture is adjusted on the bottom , in an area where the patient &# 39 ; s buttocks rest when he is lying on the underlay 1 . this aperture 48 is used for collecting the excretion , i . e . urine and excrement , of the patient . accordingly , a bedpan is adjusted underneath this aperture , so that the patient can relieve himself . this arrangement means a remarkable help in treating chronic patients in hospitals , because now the nurse doe snot have to lift the patient manually out of bed and then adjust the bedpan , which is uncomfortable for the patient . the aperture 48 for the bedpan can be arranged by means of a hatch 49 , as is illustrated in fig1 . the hatch 49 is a stretch of the bottom 40 , which can be turned aside from underneath the patient when the bedpan is needed . the underlay 1 can be provided underneath with heat insulation , as is shown in fig1 . in this case the underlay 1 comprises a heat insulation layer 50 , which in all essential length and width measures corresponds to those of the underlay 1 . it is detachably fastened under the underlay 1 for instance by means of straps 51 or other suitable fastening means . the straps 51 are attached for example by means of clasps to the support railings 42 located on the long sides of the underlay 1 , and are brought under the insulation layer and fastened to the other support railing 42 on the opposite side . the heat insulation layer 50 can be formed of a suitable heat insulating material known as such , for instance of felt , polyurethane or the like . in the bed of the present invention , particularly in connection with the support frame thereof , there can be provided means for measuring the patient &# 39 ; s weight . for example in between the bearing 12 of the vertical support member and the tubular member 10 in fig4 there can be installed a power sensor 52 which measures compressive force . by means of this , the total weight of the support frame 2 , the connected equipment plus the patient p can be measured . the signal obtained from the power sensor 52 is processed with some suitable processor 53 , such as microprocessor , and the patient &# 39 ; s weight is indicated for example in a digital display 54 . in the above specification the invention has been mainly explained with reference to a few preferred embodiments , but it is pointed out that the invention can be modified in many ways within the scope of the inventional idea defined in the appended patent claims .
