Abstract

One lengthwise side of the bed has at least one side-barrier which can be lowered and raised and comprise at least one roller-blind type length of material. At least two separate spaced apart roller blinds (10) made of textile, rubbery or plastic material, are positioned in the bed's lengthwise direction. The material is wound onto and off a shaft or roller at the side of the bed. Preferably two swivel arms are positioned behind and support the roller blind material.

Description

The present invention relates to a hospital or nursing bed at least one side barrier on one long side, where the barrier is a kind of roller shutter or a roller blind that can be rolled up Path includes which from a lower position in which the Entry into the bed on the long side is exposed in an upper position, in which this forms a side barrier, can be pulled up and this barrier can be locked in the upper position.

A hospital or nursing bed of the type mentioned at the beginning is for Example known from German utility model 1 718 671 become. In this known bed is on the long side of the Roller shutters arranged in a guide can be pulled up into a Shut-off. In this shut-off position, however, is the entry or exit along the entire length of the long side of the bed shielded. As a result, the patient is against falling out secured, but there is also the disadvantage of having access to the patents for a doctor or a caregiver, for example over the entire long side of the bed is not possible and to do so the shutter must first be lowered. Moreover blocks the one that extends the entire length of the bed Roller shutters in the raised position give the patient a view Side. A division of the roller shutter into several However, individual sections across the length of the bed is seen at this construction is not possible, because then the one for a roller shutter necessary guidance is missing at least on one side.

The object of the present invention is therefore a Sick bed or nursing bed with a side barrier a roller shutter or a roller blind-like roll of the entrance mentioned type constructively so that a lateral Barrier is possible that is only part of the length of the Long side of the bed extends.

An inventive bed provides the solution to this problem or care bed of the type mentioned at the beginning with the characteristic features of the main claim. According to one The first preferred variant of the invention provides a further development before that for guiding at least one roller shutter two each the front sides are provided adjacent to these, the from a substantially horizontal lower Non-use position around a horizontal axis in an upright position Position are pivotable in which they are the management function for the Exercise roller shutters. Are in the lowered position of the roller shutter so these swivel arms in a lower position panned in the entry or exit or access via the Long side of the bed is easily possible without the swiveling arms are a hindrance. However, the arms are in pivoted about an upright position, then they serve as Guide for the roller shutter, for example by placing the arms on the The side facing the roller shutter has a corresponding one Have guide device. This makes it possible to use the roller shutters with a length that extends only over part of the open Long side of the bed extends because with two swivel arms per Roller shutters are guided at both ends of the roller shutter and the position of the pivotable arms in accordance with the The length of the barrier through the roller shutter can be selected.

According to a development of the invention, there are at least two preferably spaced roller shutters for one Provided along the length of the bed, usually two each Swivel arms for guiding a roller shutter on both sides each roller shutter are provided. This makes it possible for the bed to shut off each only over a partial length on the long side, whereby for example, the shutters on the head of the bed can pull up or down to lock or shut there open regardless of the barrier in the rest of the area. Optional you can then, for example, only the shutters pull up towards the foot of the bed so that the Area of the patient's head and upper body, for example is accessible to doctors or nurses. This also has the Advantage that the patient can see the bed from the long side to the outside but still has the barrier on the foot side there is security against falling out. After the same In principle, you can have more than two on one long side of the bed Arrange roller shutters, the same or different lengths can have as well as the same or different distances with each other and from the head or foot of the bed. Everyone shutters is independent of the position of the other roller shutters movable, which means that the side of the bed is essentially locked can be set more flexibly. The shared side barrier with two or more shutters also has the advantage of providing protection if, for example, the backrest is angled and the patient is in the sitting position.

Preferably, as a guide for the roller shutter in at least one at least one groove is provided for the swivel arms. Shutters this Kind often consist of profile bars and these profile bars can then be guided in the groove mentioned.

For the upper locking of the roller shutter in the shut-off position preferably locking means, for example pens or the like on Roller shutters provided, for example in the locked position can engage upper recesses in the swivel arms. In order to one can release these locking means to lower the roller shutter preferably at least one grip element is present. The Handle element is preferably designed such that of which the locking means can be pulled out of their locking position are, preferably from a recess in the swivel arm are extractable.

According to a preferred constructive solution, one can For example, provide a grip element, which is parallel to Rods running at the level of the roller shutter with the locking means connected is. Such a grip element can then be used for example, in a medium-sized one based on the roller shutters Arrange the area so that you can both over the grip element Can release locking means on both sides of the roller shutter. This can for example via two spaced apart grip elements happen that are movable against each other to the locking means loosen on both edges of the roller shutter at the same time, so then the roller shutter can be lowered. One can, for example Use handle elements that act against the force of at least one spring are displaceable so that this spring when pulling the In the shut-off position, the locking means in the Locking position presses, so that it then automatically the roller shutter lock.

Furthermore, one sees preferably for at least one swivel arm a swivel limit in its upright and / or lying position Position before, so this over this upright position, which for the Guidance of the roller shutter is needed, or the lower lying Position is not movable out. This swing limit can be given, for example, on a bed-side bearing part on which the swivel arm is pivotally mounted.

The guide groove for the roller shutter, which is preferably on the inside pivotable arm is provided, can be in a below the Bed area arranged guide part continue, which is advantageous is because then the leadership is not only in the upright swivel arms is given, but also in the already under the bed surface pushed part of the roller shutter when this is lowered. The swiveling bearing of the swiveling arm on the bearing part mentioned, for example, via pins, Loosen trunnion or the like, for example in a Engage the bearing hole on the swivel arm.

According to another preferred variant of the invention provided that seen in the longitudinal direction of the bed at least two independent of each other, if necessary spaced blinds are provided. Each of these blinds can for example on a rotatable in the bed side area arranged shaft or roller can be wound. The roller blind can at least partially consist of a textile, a rubber-like Material or plastic. To the roller blind in the The raised shut-off position must be stabilized according to one preferred development of the invention provided that this preferably a plate-shaped at least in the upper region for example, has metallic reinforcement. About the Stabilizing the roller blind can also be done using this reinforcement also use for the attachment of guide elements when pulling up the roller blind preferably in Guide devices are guided by swivel arms. This Swivel arms move according to a preferred development the invention from an approximately horizontal position when erecting the Roller blind in an approximately vertical position. These are preferably Swivel arms are arranged on the bedside behind the roller blind and serve to support them.

The solution according to the invention has the advantage that Use of at least two independently pull-up blinds only partially along the long side of the bed can shut off, for example, only in the head-side area or only in the foot-side area or also overall by pulling up both blinds. It is also that Use of more than two roller blinds per long side of one Betts possible in order to achieve an even finer division and thus still more flexible locking options to come. You can then one of the Leave barriers in the barrier position, for example the To secure patients against falling out and yet the other Lower part of the barrier, for example, to the patient To allow outside view or access by doctors or Nursing staff to the patient during treatment. The one in the long side of the bed provided multiple blinds can immediately adjoin one another or be spaced apart. You can essentially with the foot part and / or head part of the bed complete or have a distance from each. The shared side barrier with two or more blinds also has that The advantage that it offers protection, for example when the backrest is angled and the patient is in the sitting position.

It is preferably provided that the swiveling up of the Swivel arms to support the roller blind almost inevitably when The roller blind is pulled up. You can do this, for example provide suitable gear means that this swiveling the Arrange swivel arms when erecting the roller blind. As such Gear means for moving the swivel arms comes for example, a toothed belt or the like. If provides two swivel arms for each roller blind, then swivel this preferably when erecting the roller blind from an in essential horizontal position in the opposite direction above. You can use the ones provided for swinging up Design gear means so that this swiveling up in opposite direction of rotation via the gear means.

Furthermore, at least one locking means is provided to the to lock the raised roller blind in the shut-off position. For example, the locking means can be a bolt or the like be in a hole in at least one of the swivel arms in whose upright position intervenes. It is then preferred Means for unlocking the locking means are provided for releasing to effect the roller blind from the upper shut-off position. As Unlatching means can serve, for example, a tension element, which can be pulled out by hand, preferably against a spring force, see above that the locking mechanism when the roller blind is pulled up by the Spring force is caused almost automatically. Pulling up the Roller blind is preferably done via a handle element in the upper Area of the roller blind. If you have this handle element on the The roller blind pulls to raise them, the two swivel Swivel arms with and thus already stabilize the roller blind with this movement in the intermediate positions between the lower one and the upper position. If you like like this preferably is provided, the swivel arms for guiding the roller blind uses them, for example as management facilities Have elongated holes in which are then arranged on the roller blind associated guide elements when pulling the Intervene roller blind.

The features mentioned in the subclaims relate to preferred developments of the task solution according to the invention.

The illustration shows a schematically simplified side view of a hospital or nursing bed according to the invention, in which essential only those important within the scope of the present invention Parts are shown. The bed usually consists of one mobile underframe 1, a bed frame 2 and one on the a side adjoining head part 3 and a foot part 4 on the opposite side. As a rule, the bases are 1 such sick beds via suitable lifting devices in the Adjustable height. The present invention is about the side barrier on the long side of the bed surface. To do this 1, a total of four swivel arms 6 provided that each work in pairs and in the 1 are arranged approximately horizontally. This Swivel arms 6 are each pivotable about an axis 6a and they are part of a side barrier of the bed. Fig. 1 shows the lowest position of this side barrier where the bed is on the long sides are free for the patient to get in and out, also along the entire length of the long side of the bed Access to the patient is possible for doctors and nursing staff.

Fig. 2 shows a corresponding view of a patient or Nursing beds of Fig. 1, in which the two shutters 9 comprehensive lateral locking of the long side of the bed into the top one Position, that is, was moved into the shut-off position. According to the invention, these form the lateral barrier Roller shutters 9 arranged so that each roller shutter 9 is only one Part of the long side of the bed extends. Both shutters 9 are can be moved independently of one another into the shut-off position. In the 2 are, for example two roller shutters arranged so that there is still one between them Gap 9a remains and that between the left roller shutter 9 and the head part 3 of the bed also a space 9b remains. The right roller shutter 9 also has a certain Distance to the foot part 4, so that a space 9c remains. This arrangement of the roller shutters 9 is in wide areas variable. There may be more than two roller shutters 9 that a different length in the longitudinal direction of the bed have and also border approximately on head part 3 and foot part 4 can or can have a smaller distance between them. The main point is that the shutters 9 are independent can be lifted from each other into the shut-off position or can be lowered into a position as shown in Fig. 1 is. This makes it possible to have a partial lowering, for example to make only one of the roller shutters 9 in FIG. 2, so that the The long side of the bed is partly free and partly closed off.

Reference is now made to FIG. 3 below. The representation shows an enlarged view of only one roller shutter 9, which from a row of parallel profile bars arranged one above the other can exist, for example similar to a window used shutters. You can see here that the two in the upright position shown swivel arms 6 a guide for form the roller shutter. To the side of the roller shutter 9 is a part on the left 13 of the mattress frame recognizable. The roller shutter 9 is in one Guide in the two swivel arms 6, for example in a groove pulled up and can be in the top shut-off position Locking means 17 locked in the form of pins or the like become. The roller shutter 9 can be raised, for example, by means of the transverse rod 12 arranged in the upper region that can be gripped by hand. At their ends is this rod 12 each connected to two tabs 11, 15, which are extend downwards. About in the middle of the roller shutter are two spaced apart handle elements 16. By moving both handle elements against each other, the Locking means 17 on both edges of the roller shutter from it Detent are pulled out at the same time, the Handle elements 16 preferably against the force of at least one Spring 18 are slidable. After pulling out the Locking means 17, the roller shutter 9 is unlocked and can be lowered become. In contrast, when pulling up the roller shutter 9 Spring 18 reaches the locking means 17, for example pins are moving themselves in recesses in the swivel arms and thus almost a snap in the upper shut-off position he follows.

Fig. 4 shows a longitudinal section through the roller shutter according to Fig. 3. Man recognizes the tab 11 in the upper area with the one in the transverse direction extending rod 12. In the lower area is part of the Mattress frame 13 recognizable. You can also see that a guide part 21 arranged below the mattress frame 13 is present, within which a guide groove 22 is provided, which the continuation of the guide groove for the roller shutter 9 within the forms two swivel arms 6, so that when lowering the roller shutter this in its lower area also below the Mattress frame 13 is guided.

In the following, reference is made to FIG. 5 and based on this The details of the construction of the Roller shutter 9 easier to understand. You can see in the Exploded view of the two swivel arms 6 with their Guide grooves 6b in which the profile bars of the roller shutter 9 are guided are. The two guide grooves 6b, of which only the one on the right Swivel arm 6 can be seen, are each on the inside of the Swivel arm 6, which faces the roller shutter 9. Here, you can recognize that the two handle elements 16, which are below the rod 12 are arranged and above the roller shutter 9, each with sleeves 16a are connected. These sleeves 16a are opposite each other Tabs can be moved inwards in the axial direction if the Locking means 17 are to be released. This can be better seen in Fig. 8 detect. In Fig. 8 you can see that below the sleeves 16a parallel to these extending and connected thinner rods 17a, one of which is a sleeve 16a and one each Handle element 16 is assigned. These thinner bars 17a will when operating the handle elements 16 in the direction of the arrow against the force the spring 18 moved. If the two thin rods 17a against the spring force 18 towards each other in the direction of the arrow is then moved, the pin-like ends of the rods 17a, which the Form locking means 17, from locking holes (not shown) pulled out and the roller shutter 9 can be lowered. A somewhat enlarged view in the central area of the sleeves 16a the two handle elements 16 is shown in FIG. 9. You can see there also that the two thin rods 17a each have struts 17b are connected to the sleeves 16a. Is inside the sleeves 16a again a rod 28, each at the ends Guide elements 29 has for the roller shutters in the Guide grooves 6b of the swivel arms 6 are guided.

Further details regarding the swivel arms 6 result from 5, 6 and 7. In Fig. 6 is a swivel arm 6 in each case presented in perspective alone. You can see the one on the inside Recognize lying groove 6b. You can also see it in the lower part of the swivel arm 6 lying swivel limit, which by a Paragraph 23 is formed. Fig. 7 shows an enlarged section in lower region of the swivel arm 6, from which one can see that the Guide groove 6b runs out horizontally there, so that the roller shutter 9 can be pushed into a horizontal position under the bed surface is, with the horizontally tapered guide groove 6b Guide groove 22 (see FIG. 4) below the mattress frame 13 can connect.

5, reference is again made. With the swivel arms 6 together acts a bed-side bearing part 24, which is in Transverse direction approximately from the lower region of one swivel arm 6 extends to the lower region of the other swivel arm 6.

On this bearing part 24 are located on both ends Areas each bearing journal 25, which is clearly visible in FIG. 7 Bearing bore 26 engage, so that the bearing for Pivotal movement of the swivel arm 6 results. The bearing pins 25 are therefore in principle in the swivel axis for the swivel arm 6. The bearing bores 26 are each approximately in the middle of one Formation 27 with a round outline in the lower area of the Swivel arm 6 (see Fig. 7). On the right side in the drawing the projection 27 is thicker than in the left side, so that the Paragraph 23 results, by means of which the swivel limitation of the Swivel arm 6 is reached in its vertical position. At the Swinging up the two swivel arms 6, which in are rotated in the opposite direction, so it becomes a Stop for a swivel arm 6 formed by the paragraph 23, so that it does not swing over the vertical position. The Paragraph 23 acts with a swivel limitation, for example corresponding molding of the bearing part 24 (not in Fig. 7 shown) together. In addition, it can be beneficial, too a swivel limitation of the swivel arm 6 in the horizontal Position (see Fig. 1) to provide what is also about a paragraph 23 in the storage area of the swivel arm and a appropriate shape of the bearing part 24 near the Bearing pin 25 can be achieved.

10 shows a schematically simplified side view of a Hospital or nursing beds according to the invention, in which only those in Important parts of the bed within the scope of the present invention are shown. In Fig. 10, the two blinds 10 are the Side barrier raised up, that is, they are in place in the shut-off position. The bed comprises an underframe 101, which in is usually mobile with hospital or nursing beds of this type. A bed frame 102 is located above the underframe, which at one end the bed with a transverse head 130 and am the other end also with a transverse one Foot part 140 is connected. The on a mattress frame (not in the Shown in detail) lying mattress 160, which is the lying surface for the Patient education is also shown. You can see that here for the longitudinal blocking of the lying surface two roller blinds 10 are arranged, each one in this example Have a distance, so that there is a space between them 10a results. The head-end roller blind 10 is also with something Distance from the head part 130 arranged so that here a space 10b remains. Likewise, the roller blind web 10 on the foot is with something Distance from the foot part 140 arranged so that here a space 10c remains. However, other dimensions of the Roller blinds 10 and another division of the side barrier the lying surface over two or more blinds 10 with more or less large distances from each other or to headboard 130 and Foot section 140 possible. This type of arrangement is broad Areas can be varied practically as desired. It is essential in the context of Invention that the two roller blinds 10 are independent of each other can be actuated so that, for example, the one roller blind 10 on the Head of the bed can be pulled up to lock there while the other roller blind 10 at the foot of the bed is in in the lowered position. The lowered position for both Roller blind sheets 10 are shown in FIG. 11. Pulling up the Roller blinds 10 can each have their upper region 105 arranged handle elements, for example in the form of rods or The like occur, as shown in Fig. 10.

11, as can be seen, is in the lowered position of the two Roller blinds 10 provide access to the lying area above the mattress 160 free on the long side of the bed.

Further details of the function of the roller blind 10 result especially from the description below 15 and 16. FIG. 15 shows the view of a single roller blind 10 in the uppermost position, in which the Roller blind is pulled all the way up and in its upper shut-off position was moved. You can recognize the two for the outside of the bed looking viewer lying behind the roller blind 10 Swivel arms 103. These two swivel arms 103 swivel each in the opposite direction when pulling the Roller blind 10 around a horizontal, in its lower end region arranged swivel axis. The swivel arms 103 have also a guide on the roller blind when pulling up the same. The function of the swivel arms 103 is also that Roller blind 10 when pulling up and in the pulled up position Support and stabilize the shut-off position. That's why they are Swivel arms slightly inclined in the uppermost position.

In its lower area there is a on the swivel arms 103 Shaped gear 111, which is better in perspective Detail view of the swivel arm 103 according to FIG. 18 can be seen. In 15, part 104 of the bed frame can also be seen. In addition, one can see that the upper right side of the roller blind 10 and On the left approximately in each case in the edge areas connecting pieces 107 are integrally formed (see also Fig. 16), the one above the Take up the blind sheet 10 in the transverse direction extending rod 105, which serves as a grip element for pulling up the blind web 10. In the 16 can be the position of one behind the Recognize roller blind 10 lying swivel arm 103 and it is a hint of a guide element 106 which can be seen in the Pull up the roller blind 10 and swing up the swivel arms 103 each in an elongated hole 123 serving as a guide device (see also Fig. 18) is performed.

A serves as a transmission means for the movement of the swivel arms 103 Toothed belt 112, each of two in the lower Gears 111 located on end regions on the swivel arms 103 is excited (see also Fig. 18). Through the guide elements 106, which are connected to the roller blind 10, when pulling up the roller blind the two swivel arms 103 each in one 15 moves pivotal movement in the direction of arrow. The opposite pivoting movement of the two pivot arms 103 results thereby by the arrangement of the toothed belt 112, which in middle region is arranged crosswise, as can be seen in FIGS. 12 and 13 in particular can be seen from the detailed view.

In the upper position of the roller blind 10 is a lock provided via locking means 115, which are shown in Fig. 17 and cooperate with the swivel arms 103 in each case. Fig. 17 shows a detail section B of Fig. 15 in the lower right corner of a blind 10. You can see the lower end of the swivel arm 103 in a fully erect position. As a locking means 115 a kind of bolt is provided which can be pulled out in the direction of the arrow via the pull button-like pull element 113. This pin 115 is there against the spring force of a spring 114 in a bore of the Tension element 113 stored. In the lower area is on Swivel arm 103 has a recess 103a on the side, which is shown in FIG is recognizable. When the swing arm 103 is approximately upright has reached the upper position, then the pin 115 snaps into it Recess 103a of the swivel arm 103, so that the Swivel arm is locked in this upper position. Should now Lock are released, this is done via the tension element 113, which, for example, via a radial pin 116 (see Fig. 17) in engages a bore of the bolt 115 so that the bolt 115 over the tension element 113 can be pulled out of the recess 103a and thereby the lock is released and the blind sheet 10 is lowered can be.

Further details of the construction of the roller blind 10 can be found in the Remove the exploded view according to FIG. 12. You can see there the two swivel arms 103, the roller blind web 10, the toothed belt 112 with its crossover arrangement in the middle area as well as the Traction element 113. Furthermore, part of the frame 104 of the bed shown. You can also see the rod 105 and the two Connectors 107 (see also Fig. 16). Furthermore, from FIG. 12 recognizable that for the upper region of the roller blind 10 a plate-shaped, preferably metallic reinforcement in the form of a Angle plate 125 is provided, on the one hand, the roller blind 10 in upper area stabilizes and the other hand the connection to the two connectors 107 that the rod 105 hold. 12 is a bedside bearing part 124 shown on which the two swivel arms 103, for example Bearing journals 126 are pivotally mounted. An enlarged view of the bearing part 124 is shown in FIG. 19. more details regarding the function of the drive means for the movement of the Swivel arms 103 result from the detailed representations in FIG. 13 and FIG. 14. The two swivel arms 103 in FIG. 13 can be seen in FIG their lying starting position, in which they are within the bearing part 124 lie. The roller blind 10 is in a wound Condition, for example, on a roller 127 below the Swivel arms is wound, which you can also pull up in the 16 can recognize position according to the sectional view. In 13, the pin-like guide elements 106 can still be used recognize each in the elongated holes 123 of the swivel arms 103 intervention. The toothed belt 112 runs over two toothed wheels 111 in each case on the two swivel arms (see also the detailed illustration of the Swivel arm 103 according to FIG. 18). Since the timing belt 112 a Has crossover arrangement, the two pivot arms 103 pivot in opposite sense of rotation. The two swivel arms 103 are in this wound position of the roller blind 10 as can be seen in FIG. 13 recognizes one after the other, being only in the middle area overlap somewhat. Will now by lifting the rod 105 Roller blind 10 is pulled up, being from the roller 127 unwinds, then the pins 106 run in the elongated holes 123 of the Swivel arms 103 and over the toothed belt 112 are the two Swivel arms 103 in the opposite direction of rotation in the Raised position pivoted, since they behind the roller blind 10th lie, form a support for this. The as leadership elements 106 serving pins are located in the reinforcement area, the angle plate 125 forms on the roller blind 10, how to Fig. 16 recognizes. The end area with the tension element 113, the bolt engaging in a recess 103a on the swivel arm 115 and the one guided via the gear 111 on the swivel arm Timing belt 112 can be seen from the enlarged detail view 14 in more detail. 14 also shows the Bearing pin 126 of the bearing part 124, which in a bore of the Swing arm 103 engages and in principle the pivot axis of the Swivel arm forms.
