Description

The invention relates to a safety device for arrangement on a bed with a lying surface and a head end, the safety device having a frame and a holding device connected to the frame, wherein the safety device can be arranged laterally along the lying surface with the aid of the holding device in the deployed position, the frame has a first side part that can be arranged in the use position of the safety device in the area of the head end, as well as a second side part connected to it via a web arranged in the area of a lower edge of the frame and delimits an exit opening and wherein an adjustable barrier is arranged on the frame in the area of the exit opening is, with which the exit opening can be opened and closed.

It is known that some people are at increased risk of falling out of bed at night due to a physical and / or mental illness. This applies in particular to older people with disorientation or incipient or existing dementia, to people of different age groups with muscle or nerve disorders, as well as to sleepwalkers. The resulting falls are not only painful, but can also lead to serious injuries, e.g. broken bones and / or bleeding, especially in older people, e.g. due to osteoporosis or inhibited blood clotting.

As a rule, people who are at such an increased risk - whether in care at home, in a hospital or in a home - have to be provided with a care bed from which they cannot fall out or get up with difficulty or not at all. Known care beds therefore have side parts made of wood or metal, which can be folded up manually or remotely and fixed by a third person. These side parts form a barrier that prevents people lying in bed from leaving the bed.

In addition or instead, a care bed can also have a lying surface that can be lowered hydraulically, for example, in order to reduce the possible fall height and the associated risk of injury.

Disadvantages of such care beds are, among other things, the high acquisition costs, which by far exceed those of a conventional bed. Many people are also reluctant to sleep in a different bed that is unfamiliar to them, which can lead to problems, especially for people with dementia.

Another disadvantage of such a care bed is that a person who cannot leave the care bed on their own is legally imprisoned. Since this is only permitted with the express consent of the person who is considered to be locked up, the use of such a care bed must be avoided if the person concerned should refuse consent, as can happen, for example, in the case of people with dementia.

Safety devices for placing on a bed are for example off EP 1 243 207 A1 , EP 0 734 004 A1 and DE 84 28 037 U1 known.

The invention is based on the object of providing a safety device of the type mentioned at the beginning which does not have the disadvantages of the prior art. In particular, the invention provides an inexpensive alternative to care beds, which can prevent people from falling out of the bed without them being locked in.

This object is achieved according to the invention with a safety device which has the features of claim 1.

Preferred and advantageous embodiments of the invention are the subject of the subclaims.

According to the invention, it is provided that the adjustment device is connected to the barrier via a cable pull system, which is preferably arranged in the frame, that the adjustment device has a pull rope and a fixing device, and that the adjustment device is arranged in and on the first side part of the frame, so that the barrier can be adjusted independently by a person lying in bed via the adjustment device from the lying surface.

The advantage of the safety device according to the invention is that it can be arranged or mounted in a simple and uncomplicated manner on existing, conventional beds, so that costs can be saved compared to buying your own care bed. It is also advantageous that in the safety device according to the invention a frame is provided which does not have to be adjusted in order to enable a person lying in bed to leave the bed. This frame not only forms a stable support structure for the adjustable barrier, but can also be used as an entry or exit aid by a person who wants to use or leave the bed. Furthermore, different devices, such as an adjusting device for opening or closing the barrier or a radio device, can be arranged on or in the frame.

In particular, an embodiment is preferred within the scope of the invention in which the frame can be arranged in the deployed position with the aid of the holding device in such a way that it protrudes essentially vertically upwards over the horizontally aligned lying surface and forms an essentially right angle with the lying surface. Arranged in this way, the frame delimits the lying surface of the bed on the long side without closing up a lying area of the bed reduce or without protruding into the room in which the bed is located.

Also preferred is an embodiment in which the frame delimits the exit opening laterally and downwards and in which the barrier on the frame is guided on both sides of the exit opening in a guide, in particular a vertical guide, so that the barrier can be lowered and raised. It is particularly advantageous in this embodiment that the exit opening can be opened and closed without the barrier protruding into the lying area or away from the bed, since it is only lowered and raised vertically. Due to the vertical guides arranged on both sides, the barrier is guided in a particularly stable manner on the frame, since horizontal forces acting on the barrier can be introduced into the frame on both sides. According to the invention, the barrier can be adjusted from the lying surface via an adjusting device arranged on the frame, the adjusting device being arranged in the use position of the safety device in the area of the head end. The person lying in bed can adjust the barrier independently due to the adjustment device arranged in this way, so that they are not locked in the bed. Since the adjustment of the barrier via the adjustment device requires conscious and targeted action, the person lying in bed is prevented from opening the barrier accidentally or in a state of mental confusion. In particular, the barrier can be adjusted manually using the adjustment device. In addition to this, however, it can also be provided that the barrier can be adjusted automatically via the adjustment device, so that, for example, the exit opening is automatically opened from a certain time in the morning.

The adjustment device is mechanical with the barrier connected via a cable system. The advantage of this is that a mechanical connection is less prone to failure and is easy to operate and repair.

Exemplary embodiments are also conceivable in which the adjustment device is electrically connected to the barrier, for example via an electrical conductor. A wireless, electromagnetic connection, such as a radio connection, is also regarded as an electrical connection. In such embodiments, the barrier can be adjusted, for example, via an electric drive which is controlled via the adjustment device. The advantage of this is that an electrical connection can be designed to save space than a mechanical connection, that the adjustment of the barrier, for example by pressing a switch, requires little effort and that the adjustment device can be arranged flexibly on the frame, even detachable in the case of a wireless connection can.

According to the invention, the adjustment device is connected to the barrier via a cable system, the cable system preferably being arranged in the frame. In this embodiment, the adjusting device has a pull cable, which is part of the cable pull system, and a fixing device for setting or fixing the pull cable. The fixing device is preferably a clamping device, in particular a cable clamp, for example a Curry clamp, but can also be designed as a pin or eye for tying the pull cable. The cable pull system preferably has deflection pulleys over which connecting cables are guided, which establish a connection between the barrier and the pull cable. It is particularly advantageous that a cable pull system manages with few moving parts and is therefore particularly low-wear and low-noise.

For example, in one embodiment with a cable pull system as the adjusting device, the barrier can be raised from a lowered position by pulling on the pull cable. In a raised position in which the exit opening is at least partially closed by the barrier, the barrier can be fixed by fixing, in particular by clamping the pull rope to the fixing device. By releasing the pull rope on the fixing device, the barrier can be lowered into a lowered position in which the exit opening is essentially freely passable. This simple possibility of adjusting the barrier and opening or closing the exit opening can be learned and carried out quickly without the need for special technical knowledge or manual skills.

In the context of the invention, it can also be provided that the barrier comprises at least one blocking element, preferably at least two or more than two blocking elements, which extends essentially over a width of the exit opening. Such a blocking element (s) is / are supported on both sides of the exit opening on the frame, so that the barrier is particularly resistant to horizontally acting forces.

At least one locking element is preferably designed as a rod or tube, with several locking elements preferably all of the locking elements being rods or tubes. The blocking element or elements are in particular made of metal, for example steel or aluminum. In the case of several locking elements, for example, the locking element, which is arranged farthest away from the lying surface when the safety device is closed, and thus forms an upper edge of the barrier, can be made of steel for increased strength. The blocking elements arranged between the uppermost blocking element and the lying surface can be made of aluminum, for example be made to save weight. Such rods or tubes have a high level of stability and can simply be guided at their ends in vertical guides on the side of the exit opening.

In a preferred embodiment, the barrier comprises two or more than two locking elements arranged one above the other on the frame, which are connected to one another via at least one connecting element, so that a locking element arranged underneath the frame can be raised by lifting one of the locking elements, in particular above a specified height. The connecting element is, for example, a net or a web of fabric, but can also consist only of cords, ropes or chains. The connecting element is preferably a material, in particular a solid material such as linen. The advantage of this embodiment is that, due to the connecting element, only the uppermost locking element has to be adjustable, in particular raised or lowered, via the adjusting device, with the entire barrier still being adjusted by connecting the locking elements via the connecting element. Furthermore, a continuous connecting element, such as a net or a web of fabric, prevents the person lying in bed from accidentally stretching a limb between the locking elements and injuring himself in the process.

In particular, within the scope of the invention, an embodiment is preferred in which the holding device has at least one, preferably plate-shaped, holding element that is connected to the frame at a substantially right angle and protruding from the frame. It is also conceivable that the holding device has a plurality of holding elements spaced apart from one another, for example in order to save weight. The holding element (s) is / are preferably able to be arranged below the lying surface and running parallel to it. In a conventional bed, the holding element / s can, for example, between a mattress and a bed frame. The safety device is thus held in position by the weight of the mattress and the person lying on it.

In the context of the invention it is provided that the safety device can be arranged running at least half the length of the lying surface, preferably at least two thirds of the length of the lying surface, particularly preferably essentially along the entire length of the lying surface. This prevents a person from falling out of bed or getting off the side of the safety device.

In a particularly preferred embodiment, the safety device has a radio device arranged on or in the frame, by means of which a radio signal can be transmitted to an external receiver in the event of manual and / or automatic activation. It is conceivable, for example, that a dedicated receiving device, a mobile phone or a computer serves as the receiver and that the radio signal is transmitted via Bluetooth or another type of radio. By manual activation, the person lying in bed can call for help if necessary.

In particular, it is provided within the scope of the invention that the radio device can be activated automatically by adjusting the barrier via the adjusting device, in particular when lowering the barrier and opening the exit opening. This ensures that caregivers are informed should a patient open the safety device to get out of bed.

It is preferably also provided that the radio device can be activated automatically by a sensor connected to the barrier as soon as a pressure exerted on the barrier, in particular from above, exceeds a defined limit value exceeds. This means that a person entrusted with the care can also be alerted if the person lying in bed wants to get out of bed, but is currently unable to open the barrier via the adjustment device for mental or physical reasons and therefore tries to move the barrier away, in particular to push down.

Fig. 1 shows a safety device 1 according to the invention with a frame 2 in a front view, the frame 2 being shown partially open for a better understanding of the functioning of the safety device 1.

On a lower edge 3 of the frame 2 there is a plate-shaped holding element of a holding device 4 (best seen in FIG Fig. 5 ) arranged, in particular screwed, via which the safety device 1 can be arranged on a bed, not shown.

The frame 2 has an exit opening 5 which extends from an upper edge 6 of the frame in the direction of the lower edge 3 extends towards so that the frame 2 is formed substantially U-shaped. A first side part 7 of the frame 2 arranged on one side of the exit opening 5 is connected to a second side part 8 of the frame 2 arranged on another side of the exit opening 5 via a web 9 arranged in the area of the lower edge 3.

In the embodiment shown, the exit opening 5 is closed by a barrier 11 which has an upper blocking element 12 and further blocking elements 13 arranged below it. The locking elements 12, 13 are rod-shaped or tubular and are connected to one another via a connecting element 14 in the form of a web of material.

The locking elements 12, 13 of the barrier 11 extend over the entire width of the exit opening 5, the ends of the locking elements 12, 13, which protrude laterally beyond the exit opening 5, guided in vertical guides 15, which are formed in the side parts 7, 8 are.

In and on the frame 2, an adjusting device 16 is arranged which, in the embodiment shown, consists of a pull rope 17 and a fixing device 18. The pull cable 17 is part of a cable pull system 19 via which the adjustment device 16 is connected to the barrier 11. In the embodiment shown, the securing device 18 is designed as a clamping device into which the pull rope 17 can be clamped.

The cable pull system 19 has two connecting cables 21, which are each connected to one end of the uppermost locking element 12, and several deflection pulleys 22 over which the connecting cables 21 and the pulling cable 17 are guided. The connecting cables 21 are connected to the pulling cable 17 via a connection 23 which is arranged in the first side part 7.

the Figs. 2 to 4 show the safety device 1 according to the invention Fig. 1 , wherein, for the sake of clarity, the connecting element 14 without the in Fig. 1 selected pattern is shown. The barrier 11 is in the Figs. 2 to 4 shown in different positions.

Fig. 2 shows the safety device 1 with the exit opening 5 open. The blocking elements 12, 13 of the barrier 11 are completely lowered and, together with the connecting element 14 folded in this position, are essentially received in a recess 23 formed in the web 9.

In Fig. 3 the exit opening 5 is partially open and partially blocked by the barrier 11. The upper blocking element 12 is raised by the connecting cables 21, so that the connecting element 14 is tensioned between the first blocking element 12 and the further blocking element 13 arranged below and this further blocking element 13 is also raised as a result. The connecting element 14 is not tensioned between the raised further blocking element 13 and the further blocking elements 13 arranged below it, so that the lowermost further blocking elements 13 are not raised but are arranged in the recess 23.

Fig. 4 shows the safety device 1 in which the exit opening 5 is completely closed by the barrier 11. The further blocking elements 13 are raised above the top blocking element 12 and the connecting element 14, which is tensioned in all areas, the lowest of the further blocking elements 13 also remaining in this position in the recess 23 so that no gap is formed between the barrier 11 and the web 9 is.

By pulling on the pull rope 17 and fixing the pull rope 17 with the fixing device 18, the barrier can be in any position between the in Fig. 2 position shown in the the exit opening 5 is essentially completely open, and the in Fig. 4 position shown, in which the exit opening 5 is essentially completely closed, to be set. If the pull rope 17 is released from the securing device 18, the barrier 11 lowers by itself into the in Fig. 2 position shown.

Fig. 5 shows the safety device 1 according to the invention with a closed exit opening 5 in an isometric view with a view of the underside of the holding device 4.

The plate-shaped holding element of the holding device 4, which protrudes at a substantially right angle away from the frame 2, can be pushed, for example, between a mattress and a slatted frame or between a first and a further support of a conventional bed, not shown, so that the frame 2 in Substantially perpendicularly protrudes upwards from a lying surface of the bed.

The frame 2 has a through opening 24 in the first side part 7 so that the pull rope 17 is guided, as required, to one side of the frame 2 facing the lying surface or to another side of the frame 2 facing away from the lying surface can be. Fixing devices 18 are preferably provided on both sides of the frame 2, to which the pull rope 17 can be fixed. In Fig. 5 the pull rope is fixed with a fixing device 18, which is arranged on the side of the frame 2 facing the lying surface.

Within the scope of the invention it is possible that the securing device 18 is only arranged on one side of the frame 2, or on both sides of the frame 2, or inside the frame 2, but released from both sides, for example via levers, buttons or sliders can be.

Fig. 6 shows a detailed view of the opened side part 8 according to an exemplary embodiment, in which the safety device 1 has a radio device 25 which can be activated in various ways. The radio device 25 has a trigger 26 for manual activation, for example in the form of a button, which can be actuated from the side of the frame 2 which is directed towards the lying surface.

Furthermore, the radio device 25 is connected to a sensor 28a via an electrical conductor 27 arranged in the second side part 8 and can be activated via this, the sensor 28a being arranged on the connecting cable 21, which runs in the second side part 8, or around this connecting cable 21. If the barrier 11 is lowered, a certain area of the connecting cable 21, in which a signal transmitter 29a, for example a sleeve, in particular a conductive metal sleeve, is arranged on the connecting cable 21, moves past the sensor 28a, causing the sensor 28a to switch the signal transmitter 29a recognizes and the radio device 25 is activated.

In addition to the sensor 28a already described, or instead of it, a further sensor 28b can be arranged in the second side part 8. The further sensor 28b is connected to the radio device 25 via an electrical conductor 27 and has the shape of a ring which surrounds a rod-shaped further signal transmitter 29b. In the area of the further sensor 28b, the electrical conductor 27 is fixed to the connecting cable 21, for example clamped or glued to it, so that the further sensor 28b is raised when the barrier 11 is lowered. As a result, the further sensor 28b is moved from a lower, non-conductive section into an upper, conductive section of the further signal transmitter 29b and the radio device 25 is activated.

The radio device 25 can also be activated by a switch 31 which is arranged in the second side part 8 and is connected to the radio device 25 via an electrical conductor 27. For this purpose, the connecting rope 21 is guided over a free deflecting roller 32, which is arranged in the area of the switch 31 between a deflecting roller 22 located in the area of the upper edge 6 and a deflecting roller 22 located in the area of the lower edge 3 or web 9.

In contrast to the other deflection rollers 22, the free deflecting roller 32 is not rotatably mounted on an axis fixedly connected to the frame 2, but rather connected to the frame 2 via a spring element 33. In a normally loaded state of the connecting rope 21, the spring element 33 is pulled together, the free deflecting roller 32 being spaced from the switch 31. The connecting rope 21 does not run in a straight line from the lower to the upper deflecting pulley 22, but is deflected away from the exit opening 5 by the free deflecting pulley.

When pressure is exerted on the barrier 11, which closes the exit opening 5, from above, the barrier 11 lowers a little so that a tensile force is exerted on the connecting rope 21. Due to the tensile force, the connecting rope 21, which is connected to the upper locking element 12 and the pulling rope 17 fixed to the fixing device 18, is tightened between the upper and lower deflecting pulley 22, so that the free deflecting pulley 32 against a spring force of the spring element 33 to the switch 31 is moved towards. If the pressure exerted on the barrier 11 is sufficiently high, the free deflecting roller 32 presses a resilient lever arm 34 of the switch 31 against a further lever arm 35 of the switch 31. This closes a contact 36 of the switch 31 and activates the radio device 25.

As an example, all or more of the described options for activating the radio device 25 can be provided, but only one of these options or a different option can be provided.

Fig. 7 shows a detailed view of the opened first side part 7 according to a further embodiment, in which the safety device 1 according to the invention has a locking device 18 which can be released with the aid of an operating element 34.

The locking element 18 can either be open or closed and, in the embodiment shown, is a cable clamp, in particular a Curry clamp, through which the pull cable 17 is guided.

When the locking element 18 is closed, the pull rope 17 can slide or be pulled through freely in one direction, so that the barrier 11 can be pulled up and the exit opening 5 can be closed, but cannot slide back through the locking element 18 in the other direction. In the embodiment shown, this is prevented by the teeth of the rope clamp. As long as the locking element 18 is closed, the barrier 11 cannot sink due to its own weight.

If the locking element 18 is open, the pull rope 17 can slide through it in both directions. In the case of the rope clamp shown, the teeth pivot and release the pull rope 17.

An operating element arranged on the side part 7, for example a push button, is connected to a control 35 which is supplied with electrical power via an energy source 36. Furthermore, the controller 35 is equipped with a motor 37 which drives a cable element 39 via a wheel 38, and a reed contact 40, which can be closed by a magnet 41 arranged on the wheel 38.

By activating the operating element 34, the motor 37 is set in motion so that the wheel 38 begins to rotate slowly and the locking element 18 alternately opens and closes via the cable element 39. As a result, the barrier 11 begins to lower continuously and piece by piece.

When the operating element 34 is deactivated, the motor 37 is switched off as soon as the locking element 18 is closed. For this purpose, the controller 35 continuously determines with the aid of the reed contact 40 and the magnet 41 arranged on the wheel whether the locking element 18 is closed or not.

For example, a circuit connecting the operating element 35, the energy source 36, the motor 37 and the reed contact 40 in a suitable manner serves as the control 35.

The energy source is, for example, a battery or an accumulator.

In summary, an exemplary embodiment can be shown as follows:
A safety device 1 for arrangement on a bed with a lying surface and a head end has a frame 2 and a holding device 4 connected to the frame 2. In the deployed position, the safety device 1 can be arranged laterally along the lying surface with the aid of the holding device 4. The frame 2 delimits an exit opening 5 and an adjustable barrier 11 is arranged on the frame 2 in the area of the exit opening 5, with which the exit opening 5 can be opened and closed. <u> List of reference symbols </u> 1.
