In the drawing, the invention is applied to a combined bed Bedside table depicted as preferred in hospitals, nursing homes and Rehabilitation clinics are used.

The bedside table consists essentially of a foot part designated overall by the reference character 1 , a slide 2 which is vertically adjustable with respect to the installation base, that is to say in the direction X or Y, and this slide 2 is arranged with drawers 4 or 3 arranged with respect to one another and 5 , to which a horizontal intermediate floor 6 , which is also connected to the slide 2 and serves as a cover for the drawer 4 , is assigned.

The upper drawer 5 is overlapped horizontally by a pull-out tray, which is designated overall by reference numeral 7 . The pull-out tray 7 is assigned to the carriage 2 and can also be adjusted in height with this device in the direction X or Y and - like the drawers 4 and 5 and the intermediate floor 6 - can also be locked in the desired height position. In the illustrated embodiment, the locking takes place via the self-locking of the screw spindles.

A total of four roles are assigned to the foot part 1 , of which only one is designated by the reference number 8 . The rollers 8 are approximately in the Eckbe range of the foot part 1 about a vertical axis 9 arranged infinitely pivotable Lich.

A floor pan 10 is assigned to the foot part, which depending on the height of the bedside table is accessible either from the front, from the right and left and from above, or in the lowered position (e.g. FIG. 1) only from the front. The Bo denwanne 10 extends approximately to the carriage 2 and below the lower drawer 4th In the lower position of the slide 2 and thus the drawer 4 , the floor pan 10 is arranged with free space 11 to the underside of the drawer 4 , so that the floor pan 10 remains easily accessible, at least from the front. This floor pan 10 can be used to store objects. Your floor is inclined and may have ver holes if necessary, so that the liquid can run off well when disinfected.

In the drawing, the invention is illustrated, for example, by the fact that the drawers 4 and 5 have different dimensions and thus different volumes. Of course, these drawers 4 and 5 can also be the same size. It is also possible to provide a larger drawer instead of the drawer 5 and a smaller drawer instead of the drawer 4 .

In addition, the number is not limited to two drawers. Instead, for example, three or four drawers can also be provided. Instead of a drawer 5, it is also possible to provide only one storage shelf which is connected to the carriage 2 and is therefore also adjustable in height. The same applies to drawer 4 . Here, instead of a drawer, several shelves can be arranged at a distance from one another, which are also coupled to the carriage 2 in a height-adjustable manner.

The entire structure of the bedside table shown can be modular, which means that the bedside table can be adapted according to customer requirements. This adaptation can take place, for example, in that the carriage 2 is assigned the individual parts desired by the customer, for example a drawer and several shelves, three drawers, two drawers 4 and 5 , as shown.

All these modularly prefabricated, adaptable individual parts can be connected relatively easily with the carriage 2 , possibly replaceable, in order to be able to satisfy the various customer requirements. For this purpose, the carriage 2 can have suitable coupling openings, which can be closed by blind plugs for example. These different openings can be arranged at different heights on the slide, so that drawers of different sizes, drawers of the same size, intermediate shelves, mixed if necessary, can be arranged.

As can be seen, for example, from FIGS. 1, 3, 5, 6 and 9, the two drawers 5 have recessed grips on opposite sides, of which the recessed grips 12 , 13 and 14 ( FIG. 9) are provided with reference numerals.

The recessed grips 12 , 13 and 14 can all have the same shapes and the same dimensions. The front wall 15 ( FIG. 9) of the drawer in question, for example 4 and 5, is curved inwards according to a curve 16 which is returned via a circular arc or via a curve 17 to a wall section 18 which is on the boundary surface 19 of the front wall 15 lies. The wall section 18 is pulled slightly forward relative to the curve 17 , so that the recessed grips 12 , 13 and 14 have an approximately teardrop-shaped or streamlined design in cross section with regard to their inner boundary surface. The recessed grips 12 , 13 and 14 and all other recessed recessed grips are thus shifted inwards and do not protrude outwards. Disinfection liquid can easily run, since the handle grip, gradually out area in a section plane, which is performed, for example orthogonal to that of Fig. 9 obvious sectional plane in the Begren be recycled 19, so that a crack-free total, hollow-faced boundary of the grip recesses 12, 13 and 14 results in which the user can reach in with several fingers and either push or pull the drawer.

As can be seen in particular from FIGS. 7 and 8, but also from FIGS. 1, 3 and 5 and 6, the drawer 4 is guided on guides 20 and 21 . Telescopic cables, guided on rollers or sliding guides, can be used to achieve smooth operation. The guide 20 can be carried by the intermediate floor 6 , while the guide 21 is assigned to the carriage 2 . The guides 20 and 21 run horizontally and parallel to each other.

The drawer 5 is also guided and supported by guides 22 and 23 , which can also be designed as slide or roller guides. The guides 22 and 23 run parallel to the guides 20 and 21 below the tray 7 and are indirectly connected to the carriage 2 , so that they can be adjusted in height in the direction X and Y with the drawer 5 .

As can be seen in particular in FIGS. 7 and 8, the height H of the drawer is different over its entire depth, specifically in the front area the drawer height H is considerably greater than in the rear area facing the slide 2 . Here the drawer only has the height h. As a result, objects, for example bottles, do not need to be lifted out of the drawer by the user, that is to say by a patient, over the full height H. Rather, it is easier to lift these objects forward only by height h.

In contrast, the height of the drawer 5 is formed uniformly over the cross section. This height is also considerably less than the height H or h of the drawer 4 .

The intermediate floor 6 is formed flat on its top and can also be used for storing objects, since the space 3 in the embodiment shown is dimensioned so large that objects such as books, bowls, bowls or personal utensils can be stored here.

The drawers 4 and 5 can be provided with openings (not shown) in the region of their base, so that disinfectant liquid can run off.

The carriage 2 can be seen in more detail from FIGS. 21 to 24. Fig. 23 shows for example, that is connected to the carriage 2 at the upper end of a frame 24 by several screws which are disposed on the upper end face of the carriage 2.

In the embodiment shown, the intermediate floor 6 is connected to the carriage 2 by four screws, of which only the screw 25 can be seen. A strip-like front part 26 of the guide 20 for the drawer 4 can also be clearly seen from FIG . On the inside of the slide, a profile 27 is screwed below the intermediate floor 6 , in the area of which the guide 21 is arranged. In this area, a support profile 28 (FIGS . 9 and 37 and 39) is provided, which is connected in one piece by several screws 29 to a rail 30 on the left or a rail 31 on the right. The rails 30 and 31 are approximately double U-shaped in cross section and point with their legs against one another, specifically inwards to the longitudinal axis of the slide 2 . At the upper end of the carriage 2 encapsulated gearboxes are arranged on diametrically opposite sides, namely a gearbox on the right 32 and a gearbox on the left 33 , each of which a hand crank 34 and 35 is assigned.

36 and 37 each denote a bevel gear, which is to be non-positively connected via a pinion 38 or 39 to a bearing block 40 or 41 for the hand crank 34 or 35 , which is designed as a drive wheel.

The bevel gear 36 and 37 is rotatably supported via a respective hollow shaft 42 or 43 at one end in a sleeve pipe 44 or 45 and at the other end on a Zap fenlager 46 or 47 .

Each pinion 38 and 39 is each low-friction gela via a roller bearing 48 or 49 . Each bearing block 40 and 41 is easily rotatably supported by a roller bearing 50 and 51, respectively. In addition, it can be seen particularly from FIG. 24, the bearing blocks are encapsulated toward the interior 40 and 41, so that the entire construction is naßdesinfektionsfähig.

At 52 , a cam is arranged, which is firmly connected to a brake shaft 53 . The brake shaft 53 is designed as a hollow shaft.

Coaxial with the brake shaft 53 , a crankshaft 54, which is also designed as a hollow shaft, is arranged within the same, with which the hand cranks 34 and 35 cooperate. The hand cranks 34 and 35 each have a circular-shaped part 55 or 56 , the ends of which are directed towards each other and each have a bore 57 or 58 at chamfered or tapered ends, through which one eye of a tension spring 59 extends. which is arranged in the crankshaft 54 and which has the tendency to crank the hand 34 and 35 into the crankshaft 54 .

The arcuate parts 55 and 56 are arranged in pedestals 60 and 61 , which have channel-like openings 62 and 63 , which are the circular arc-shaped parts 55 and 56 of the hand cranks 34 and 35 in shape, so that these parts 55 and 56 slide therein can, but only up to the end position shown in FIG. 24, left. The right representation in FIG. 24 shows a position of the hand crank shaft 54 , in which the hand crank shaft is arranged almost completely with its grip part 66 in a cup-shaped recess 64 , so that it does not protrude outwards. The bearing block 60 also has such a cup-shaped or cup-shaped recess 65 . The cup-shaped recesses 64 and 65 are directed inwards and towards one another. With 67 a handle portion of the crank handle 35 is also referred to net. If the hand cranks 34 and 35 are not used, they are drawn into the tubular hand crank shaft 54 by the tension spring 59 and then do not interfere with either. If one of the hand cranks is to be used, it is pulled out against the restoring force of the tension spring 59 by applying a pulling force to the relevant hand crank, for example up to the position shown in FIG. 24, left. The arcuate parts 55 and 56 are of flat oval design in cross section in the embodiment shown, while the free ends 68 and 69 are rectangular in cross section and are orthogonal to the long axis of the oval. Since the channel-like openings 62 and 63 are adapted to the oval cross-sectional shape of the circular parts 55 and 56 , the parts 68 and 69 which are rectangular in cross section limit the outward movement of the circular parts 55 and 56 . Due to the special shape of the channel-shaped openings 62 and 63 on the one hand and the circularly arcuate parts 55 and 56 of the hand cranks 34 and 35 slidably arranged therein on the other hand, a frictional connection between the circular-shaped parts 55 and 56 and the relevant bearing block 60 and 61 is Herge provides , so that when applying a torque to the hand cranks 34 and 35, the bearing blocks 60 and 61 and via this the gears connected with them ver gear 38 and 39 and the respective bevel gear 36 and 37 are rotated.

The bevel gears 36 and 37 mesh with a further pinion 70 or 71 , the axis of rotation of which is orthogonal to the axis of rotation of the bevel gears 36 and 37 , the axes of rotation of the bevel gear 36 on the one hand and of the pinion 70 and the axis of rotation of the bevel gear 37 and the axis of rotation cut the pinion 71 at one point. These points lie otherwise on a straight connecting line which is orthogonal to the longitudinal axis of rotation of the pinions 70 and 71 and which is designated by the reference numeral 72 ( FIG. 24).

On each side of the vertical line of symmetry 73 ( FIG. 11) of the bedside table there is a self-locking screw spindle 74 and 75 , respectively, which run parallel to the line of symmetry 73 and vertically to the base. In addition, the longitudinal axes of these screw spindles 74 and 75 run parallel to one another.

With 76 and 77 , clamps are designated, which encompass the thread-free upper ends of the screw spindles 74 and 75 . Rolling bearings can be seen here in order to achieve smooth rotation of the screw spindles 74 and 75 . The clamps 76 and 77 connect the spindles to the slide 2 .

At each end of each screw spindle 74 and 75 , one of the pinions 70 and 71 is rotatably mounted, for example by a screw inserted at the end, so that each of the spindles 74 and 75 by rotating one of the hand cranks 34 and 35 , for example the crank 35 synchronously and at the same time via the hand crankshaft 54 is rotated.

Each of the spindles 74 and 75 passes through a is in a crossbar 78 arranged nut 79 which in detail in FIGS. 41 to 45 is to erse hen. Each screw nut 79 of each of the screw spindles 74 and 75 is assigned a stop 80 or 81 ( FIG. 53), which has two through bores 82 and 83 . In addition, the plate-shaped stop 80 and 81 is delimited on one side by a straight side wall 84 and by two orthogonally extending side walls 85 and 86 , while it is provided on the side opposite the side wall 84 with a groove-like recess 87 , which is approximately the same Outside diameter of the nut 79 is adjusted. This fillet-like recess 87 has a plurality of tooth-shaped recesses 88 , which are arranged by the fillet-like recess 87 ge circular arc distributed at regular intervals.

The screw nut 79 is designed in cross section ( FIG. 45) in the manner of a triangle with rounded corner regions 89 , 90 , 91 . The other Dreiecksei th are straight. One-piece locking tabs 92 , 93 and 94 protrude in the same direction from these triangular sides.

A flange is designated by 95 , while 96 represents a hexagon head.

The tooth-shaped recesses 88 engage over one or two locking tabs 92 to 94 and thereby prevent rotation of the screw nut 79 in question , which are arranged in a suitable recess in the crossmember 78 .

After loosening the stops 80 and 81 , the screw spindles 74 and 75 and thus also the screw nuts 79 in question can be adjusted accordingly.

The spindles 74 and 75 are due to the gear designs under different common, namely the screw 74 is left-handed and the screw 75 is right-handed.

The stops 80 and 81 also prevent the carriage 2 from moving upwards.

Between the two screw spindles 74 and 75 , specifically in the embodiment shown in the embodiment coaxial with the line of symmetry 73 , a gas pressure spring 97 is arranged, which is coupled with its upper telescopic part 98 with a cross member 99 , which is assigned to the pull-out tray 7 . The lower telescopic part 100 is arranged via a spherical or spherical end 101 ( FIG. 7) in a spherical joint socket 102 so that it can move in space. The ball joint socket 102 is arranged in one piece on the foot part 1 .

The gas pressure spring 97 is dimensioned so that it essentially compensates the resulting weight of the pull-out tray 7 , the drawers 4 and 5 and the parts connected therewith, so that the operator can make a height adjustment in the direction X or Y without great effort, and even if there should be 6 items in the drawers 4 and 5 and on the intermediate floor. Several gas pressure springs can also be provided.

Reference number 103 denotes a Bowden cable which is connected to a lever 104 ( FIG. 23). This lever 104 is assigned to the outside of one of the gear housing, for example from the gear 33 , Hervra gender actuating lever 105 , via which the Bowden cable 103 and thus a brake to be described below can be actuated for one or more of the rollers 8 .

106 designates a tube assigned to the Bowden cable 103 , which is arranged on the crossbar 78 .

In the illustrated embodiment, all four wheels 8 are braked. If the operating lever 105 is released, all the rollers 8 are in the braked position. For this purpose, a type of frame 107 is arranged below the foot part 1 , which essentially consists of a crossbar 108 ( FIGS. 7 and 8) extending next to the floor pan 10 and transversely thereto and a brake lever running orthogonally to this. Depending on an operating lever is weils each arranged in the region of a longitudinal side of the base 1 and extends Zvi rule the foot part 1 and the transverse beam 108th For reasons of clarity, only one brake lever has been given the reference number 109 . The arranged on the opposite side of the brake lever 109 is accordingly designed. The crossbar 108 and the two brake levers 109 thus form a kind of H-shaped frame 107 , the crossbar 108 not being exactly on the center line of the brake beam 109 , but somewhat displaced from one side to the center ( FIGS. 7 and 8). The brake lever 109 and thus indirectly also the crossbar 108 are mounted against the restoring force of springs 110 , 111 , which are arranged in the area of the corner points of the foot part 1 and which have the tendency to always leave the brake in the locked position, so that this at Non-actuation is always engaged. These springs 110 , 111 are mounted on the axles 9 of the rollers 8 . These axes clearly emerge from FIGS. 25 to 29.

In a roller body 112 of each roller 8 , a cylindrical pin 113 is longitudinally displaceable, ie slidable. The longitudinal axis of the cylindrical pin 113 and thus also the bore runs parallel to the longitudinal axis of the axis 9 of the roller 8 in question , that is to say orthogonally to the base of the bedside table.

The free, lower end of the cylindrical pin 113 is mounted in a joint socket of a brake lever 114 , which represents an angle lever that extends around a limited pivot axis 115 in the direction A or B in the direction A or B, which is orthogonal to the longitudinal axis of the axis 9 and thus also the cylindrical pin 113 Dimension is pivotally arranged. When pivoting in direction A, the restoring force of a compression spring 117 must be overcome, which has the tendency to pivot the brake lever 114 in direction B.

With the brake lever 114 each brake cams 118 are connected, which can engage in correspondingly adapted tooth-shaped recesses 119 ( Fig. 26) of the roller 8 . A plurality of such tooth-shaped recesses 119 is arranged over the circumference of each roller 8 . All tooth-shaped savings 119 have the same shape and the same dimensions and are distributed net evenly over the circumference of the roller. This makes it possible to block the rollers 8 by positive locking after a very small displacement of the bedside table.

Of course, only one roller 8 or two pairs of opposing rollers 8 can be assigned a brake.

If the brakes are to be released, then the actuating lever 105 and the Bowden cable 103 push the cylindrical pins 113 upwards against the restoring force of the springs 110 , 111 of the frame 107 by the compression spring 117 , as a result of which the brake levers 114 are pivoted accordingly in direction B, so that the brake cams 118 come out of the tooth-shaped recesses 119 . The roller 8 in question is then freely rotatable.

Reference numerals 122 and 123 ( FIG. 16) denote columns which run orthogonally to the floor. A cover plate is assigned between the columns on the side facing the body or the drawers 4 and 5 . Another cover is designated 125 . The covers bridge the space between the columns 122 and 123 so that the carriage has a closed exterior.

At 126 a lower crossbar is arranged, which, like the upper crossbar 78 and the right column 122 and the left column 123, consists of hollow profile bodies which have a high moment of inertia with a relatively low weight.

At their upper ends, the columns 122 and 123 carry on their mutually facing, outward-facing side faces each eight roles, which are net to four roles 128 , 129 and 130 , 131 spaced one above the other. These rollers 128 to 131 engage in vertically extending channels 132 , 133 and 134 , 135 of guide profiles 136 and 137 designed as columns ( FIG. 9), so that the carriage 2 in the vertical direction (XY) is smooth, essentially free of play in its adjustment in the direction X or Y leads and is stored. Reference numeral 124 designates screws through which the columns 136 , 137 are connected to the foot part 1 .

With 78 a crossbar is designated. On the opposite side there is also a traverse ( Fig. 16).

Each drawer 4 and 5 is assigned a drawer lock, which can be switched and limits the extension path of the drawer 4 and 5 in question, so that the drawer 4 , 5 cannot be pushed further beyond its insertion position, for example to the opposite side. The direction of actuation can be changed by the relevant drawer lock for right or left use.

From FIGS. 9 and 32 to 36 it can be seen that the drawer lock has a double-armed locking rocker 139 which is pivotable in the central region about a pivot axis 140 ( FIG. 9) by a limited amount in the vertical direction, that is to say the pivot axis 140 extends with a horizontally extending shelf for the bedside table also horizontal. The locking rocker 139 has a locking cam 141 or 142 at its ends. The locking cams are directed towards the same side of the locking rocker and run with their longitudinal axes parallel to each other and are of the same size and shape, in the present case formed as circular cams in cross section.

Each support profile 28 for the drawer 4 or 5 has on its front side supplied to the locking rocker 139 a plurality of offset portions 143 , 144 and 145 , 146 ( FIG. 37), whereby sheet metal tabs of the support profile 28 in question are formed by punching, which are the same size and protrude by the same amount from the Seitenwan extension of the support profile 28 in the direction of the locking rocker 139 . Depending on the desired direction of insertion and thus also the blocking direction of the drawer 4 or 5 concerned , the locking rocker 139 is pivoted about its pivot axis 140 . Then the cams 141 , 142 meet the offsets 143 , 144 and 145 , 146 , depending on the pivoting direction of the locking rocker 139 and then block the drawer 4 or 5 in the inserted position in the desired direction.

The locking rocker 139 can be pivoted after pulling out the relevant drawer 4 or 5 without tools. The arrangement can be made such that the locking rocker 139, while overcoming a certain frictional connection into the respective swivel position by rubbing on the offsets 143 , 146 and 144 , 145 , does not move independently, even then, if the drawer 4 , 5 should be closed with greater force.

As can be seen in particular from FIGS. 7 and 8 and 46 to 50, the pull-out tray 7 essentially consists of two tablet parts 147 and 148 which can be telescopically pushed into one another, that is to say the tablet part 148 is completely in the inserted position shown in FIG. 8 inside the tablet part 147 .

The reference numeral 149 ( FIG. 46) denotes a pull rod which penetrates a central bore of a piston 151 via a screw 150 and is screwed to it. The piston 151 is encompassed by a hollow piston 152 , which is integrally connected on its end facing away from the pull rod 149 with a pipe socket 153 open on one side, in which a compression spring 154 is arranged, which is directed against a wall section 155 directed orthogonally to the longitudinal axis of the pull rod 149 the tablet part 148 resiliently supports and thereby resiliently intercepts the pull-out movement.

At an axial distance from the wall section 155 there is a pull-out nose 156 which projects downwards and orthogonally to the tablet part 148 and can be gripped from below, in front, in order to pull out the pull-out tray 7 ( FIG. 7).

The hollow piston 152 is supported in the interior of the tablet part 148 and connected in one piece via a pipe 157 to a sleeve part 158 , which delimits the end of the tablet part 148 on the end face facing the tablet part 147 .

The pull rod 149 is at its cut from the hollow piston 152 Längenab connected by a piston 159 and penetrates it with free wheel. At the end of the pull rod 149 , a conical body 160 is arranged in one piece with the pull rod 149 , the diameter of which is larger than a through-opening 161 which narrows conically in the direction of the conical body 160 in the piston 159 . In this way, the pull rod 149 can slide over a certain length through the through opening 161 of the piston 159 .

The piston 159 is arranged in one piece in the end face of a coupling tube 162 , which in turn is telescopically arranged in the tube 157 in a longitudinally movable manner. This coupling tube 162 is provided with a locking flange 163 which extends orthogonally to the longitudinal axis 164 of the tablet part 148 .

Reference numeral 165 denotes a lower cover of the tablet part 148 . The cover 165 is connected to the tablet part 148 via numerous screws 166 .

The lines 167 and 168 denote bead-shaped, channel-shaped impressions of the cover 165 . Other features are arranged in the area of the bores for the screws 166, which are arranged in pairs and symmetrically to the longitudinal axis 164 and here take up the tube 157 in the manner of a bearing pan.

With 169 another tube is designated, which is guided telescopically in the tube 162 by a limited amount of longitudinal displacement. The tube 169 has on its end section facing the tablet part 147 a plate 170 which closes it flush, but which has an excellent nose 171 with at least one longitudinal slot 172 through which at least one, preferably several screws 173 ( FIG. 7) Reach through orthogonally to the longitudinal axis 164 and secure the pipe against twisting. The screw 173 or the screws are screwed into a bead-like thickened edge region 174 ( FIG. 7) of the tablet part 147 . The holes are accessible from below after the cover 165 is removed.

In the mouth of the coupling tube 162, a stopper plug 175 is assigned which limits the extraction stroke by abutting against a shoulder 176 (Fig. 7).

As can be seen from Fig. 7, the edge region 177 closes immediately in the fully extended state of the pull-out part 148 with the locking flange 163 . The arrangement has been made so that the locking flange 163 runs in the area of the edge region 179 on its underside over a slope on an increase or thickening 178 which is dimensioned such that the pull-out part 148 is shifted upward by a few angular degrees from its horizontal position is, and when loaded on the one hand by the pull-out part 148 , on the other hand by placing objects in its horizontal or approximately horizontal position. An edge region 179 of the pull-out part 148 slides under the edge region 177 of the pull-out part 147 when it is pushed in, so that the pull-out part 148 comes to lie completely below the pull-out part 147 in the inserted state ( FIG. 8) and is completely inserted therein. It can also be seen that the freely accessible top surface of the pull-out part 148 corresponds to one hundred percent or approximately one hundred percent of the freely accessible surface (length) of the pull-out part 147 or is only slightly shorter.

On both sides of the pull-out part 148 , slide catches 180 and 181 are arranged in the end region thereof, which can be displaced against the restoring force of a compression spring 154 via a two-armed coupling lever 182 and 183 .

Each of the clutch levers 182 and 183 has at its end an approximately fully circular coupling part 184 and 185 , which is formed as a flat disk and is flat on opposite sides and whose longitudinal axis is rotated 90 degrees with respect to the longitudinal axis 164 . The coupling parts 184 and 185 are coupled over a correspondingly shaped circular driver recess with the respective slide catch 180 and 181 to a limited extent pivotably or rotatably. One of these recesses is indicated at 186 in Fig. 49 with a reference numeral.

The pipe socket 153 is integrally connected to the central part of the two-armed coupling lever 182 , 183 , such that the longitudinal axis 164 extends coaxially with the longitudinal axis of the pipe socket 153 and thus also coaxially with the longitudinal axis of the compression spring 154 .

With the side of the two-armed coupling lever 182 , 183 opposite the pipe socket 153 , the enlarged-diameter hollow piston 152 is arranged, which is provided with axially extending end teeth 187 .

The spur toothing 187 engages in a shape-matched spur toothing 188 of a spur gear coupling 189 of the tube 157 , which is integrally connected to the locking flange 163 . The longitudinal axis 190 of the tube 157 runs coaxially to the longitudinal axis 164 of the tablet part 148 . The tube 157 is connected in one piece by three bearings and clamps to the cover 165 of the tablet part 148 . Of these clamps and bearings, only the middle lines 191 , 192 and 193 in Fig. 47 are shown. Also shown are pairs of screws 194 , 195 and 196 , through which the clamps and bearings with the cover 165 are fixed, but releasably connected to the pipe 157 to keep it. The tube therefore engages under the pull-out part 148 of the tray practically over its entire length.

By actuating one of the slide catches 180 or 181 , the clutch lever 182 , 183 , the hollow piston 152 and its spur toothing 187 are brought out of clutch engagement with the spur toothing 188 of the tube 157 . As long as this takes place, the pull-out part 148 of the pull-out tablet 7 can be rotated through 360 degrees in both directions about the longitudinal axis 164 , 190 . After releasing the relevant slide catch 180 , 181, the end toothing 187 again engages in the end toothing 188 and locks the pull-out part 148 of the pull-out tray 7 . In this way, the pull-out part 148 can be set and locked in numerous angular positions relative to the horizontal.

It will also be clearly seen from Fig. 49 that the wall thickness of the lever is dimensioned considerably thinner relative to the hollow piston 182 182 and 183. In this way, the levers 182 and 183 are able to spring or deflect to some extent.

The tube 157 is telescopically displaceable by the tube 162 .

Fig. 8 reveals the bedside table in its completely shut down position with inserted tray 7 .

In contrast to the illustrated embodiment, instead of screw other suitable me spindles for height adjustment of the bedside table Chan drives, for example alternately on both sides by pressure medium pressure, particularly by hydraulic pressure, piston-cylinder Units may be provided.

It is also possible to use other linear motors, for example to replace electrical units, for example with spindles that are driven by electric motors or motor spindles. Motor spindles can have a motor concentrically surrounding the spindle.

Furthermore, it is possible to use racks instead of spindles are driven via pinions or the pinions are driven and the Racks remain stationary.

Instead of two screw spindles, only one can dimen accordingly sioned middle spindle or just another motor drive, for example play a linear motor, can be provided.  

Instead of arranging the manual operation for manual drives immediately below the pull-out tray 7 on the side normally assigned to the sickbed, this drive can also be provided in the middle height range of the bedside table.

Furthermore, instead of manual actuation, it is also possible to additionally or instead use a motor drive that works with electric motors. It is possible, in addition or instead, to provide a buffer battery, for example in the lower drawer 4 , which actuates the motor drive for the height adjustment of the combined bed-night table. However, the energy can also be provided via one or more solar cells.

Instead of providing two slide catches on both sides of the pull-out part 148 , it is also possible to provide only one slide catch on one side or an actuation key, for example on the front side of the pull-out part 148 .

Instead of using brakes which act on each individual roller 8 , it is also possible to use a brake which acts on only one roller or on a few rollers.

Instead of a positive brake, a brake can also be provided against each other via a Bowden cable and one or more brake pads supports the ground directly and thereby creates a frictional connection  between the brake shoe in question and the base for the night manufactures table. Only one brake pad or several brake pads, for example, be assigned to each of the roles, but without the roles themselves act.

A motor-driven or foot-driven can also be used to provide energy bene hydraulic pump can be assigned to the combined bedside table, of a corresponding hydraulic drive, for example a different one Piston-cylinder unit to be pressurized with hydraulic pressure on both sides supplied with hydraulic pressure.

Instead of - as shown for example in Fig. 24 - hand cranks with circular arc-shaped cranks 34 and 35 and circular-arcuate parts 55 and 56 , it is also possible to provide retractable crank arms on slopes, that is not on arcs, which provide the frictional connection between the Hand crank and the bevels.

Instead of a telescopic table top with tablet parts 147 and 148 , a snap frame can also be used. This can essentially be made of two parallel supports or tubes, on which the bed-top parts can be folded about their transverse or longitudinal axis and thus arranged on top of each other. It is possible, for example, to open the pull-out part 148 about a transverse axis on the part 147 and to arrange it flat in the non-use position of the part 148 .

The drawers 4 and 5 do not need on parallel rails, but NEN can also be guided on an arc-shaped rails that lead the drawers after they are pulled out on a circular arc to the user and in the non-use position, the drawers on, for example, an upwardly convex arc-shaped rail lead into the non-use position.

It can also be clearly seen from the drawing that the combined bedside table in side view ( Fig. 1) has an approximately C- or U-shaped Grundge shape, with one leg of the "U" through the drawer together with the above tablet part located, the other U-leg are formed by the lower drawer or the intermediate floor 6 arranged above it and the connecting web connecting the U-leg is formed by the carriage 2 .

The foot part 1 , on the other hand, forms with the columns 122 and 123 in the side view according to FIG. 5 an approximately inverted T-shaped shape.

The pull-out plate 7 is about the pivot point of the gear 32 and 33 , that is, about a horizontal, imaginary axis shown in the drawing in the pulled-out state of the tablet parts 147 , 148 in the direction X, that is in the direction of the installation floor, adjustable by a limited acute angle and can also be locked in the desired position. In this way, tablet parts 147 and 148 are washable and disinfectable, and the liquid can drain off well. In addition, not so much space is required, since this reduces the storage space. Otherwise the storage space might not be sufficient.

The in the summary, in the claims and in the description Exercise described features can be used individually or in any Combinations may be essential for the implementation of the invention.
