Description

The present invention relates to an arrangement for securing a bed occupant against falling out of a bed, in particular a nursing bed, wherein the securing arrangement has at least one telescopic rail guide.

From the documents EP 2 263 632 A1 . EP 1 243 207 A1 . EP 2 052 707 A1 . DE 20 2015 101 436 U1 and EN 20 2016 104 234 U1 are known safety arrangements. Especially from the document EP 2 052 707 A1 known fuse arrangement has achieved a great reputation. It has proven itself in everyday life in hospitals and nursing homes. In years since the development of the document EP 2 052 707 A1 known fuse arrangement has repeatedly revealed the need for improvements of the fuse arrangement. This need for further improvements is based on the inventions described below and specified in the claims.

In the fuse arrangement according to the document EP 2 052 707 A1 takes place the extraction of the fuse assembly and also the insertion of the fuse assembly in two steps: First, while the third guide means are pulled out of the second, then the second are pulled out of the first guide means. When inserting the securing arrangement, the third guide means are first inserted into the second, before then the second guide means can be inserted into the first. Undressing and inserting in two steps are perceived by many users as inharmonious and technical. Especially in nursing beds, where a high demand for a homely design of the bed, many users want a pleasing design not only of the outer of the bed, but also the function.

The invention was based on the first object to improve the securing arrangement so that a second guide means of the telescopic rail guide relative to a first guide means of the telescopic rail guide or a third guide means of the telescopic rail guide relative to the second guide means can be moved so that thereby a user-responsive movement is reached.

This first object is achieved according to the invention in that the securing arrangement has at least one synchronization mechanism which displaces the first guide means to the second guide means or vice versa and displaces the second guide means to the third guide means and vice versa in the first direction and in a direction opposite to the first direction synchronized.

The synchronization mechanism can be realized in a different manner in a fuse arrangement according to the invention. Two variants are described in more detail below. Other variants are not excluded.

The synchronization mechanism according to the first variant comprises at least a first rack, a second rack and gear transmission meshing the first rack and the second rack. The first rack may be attached directly or indirectly to the first guide means and / or the second rack to the third guide means. The toothed wheels meshing the toothed wheels of the gear transmission are preferably rotatably arranged in or on the second guide means. The gear transmission may have an odd number of gears. The gear transmission may be a spur gear. The two meshing the racks Gears are preferably the first and the last gear of the spur gear. The spur gear has an odd number of gears, it is achieved that the first and the last gear of the spur gear, which mesh the racks have the same direction of rotation. The serrations of the first and last sprockets running in the racks then preferably move the second guide means to which the sprockets are indirectly or directly rotatably mounted with respect to the first guide means in the same direction as moving the third guide means relative to the second guide means ,

The second variant of the synchronization mechanism comprises a first wheel, a second wheel and a pulling element, which is guided over the first and the second wheel, so that a rotation of the first wheel is transmitted to the second wheel and vice versa. Preferably, the tension member is placed as an eye and not eight around the first and second wheels, so that the rotation of the first and second wheels is in the same direction. In the second variant, the first wheel and the second wheel are preferably rotatably mounted indirectly or directly on the second guide means.

The first wheel may be rotatably and coaxially connected to a first gear and the second wheel may be rotatably and coaxially connected to a second gear. The second variant of the synchronization mechanism may also include a first rack and a second rack. The first gear may mesh with the first rack and the second gear may mesh with the second rack.

The first rack may be attached directly or indirectly to the first guide means and / or the second rack to the second guide means.

The second variant of the synchronization mechanism can have at least one tensioning device, through which the tension element is tensioned. The first wheel may be a pinion, the second wheel may be a pinion and the tension member may be a V-belt.

The from the document EP 2 052 707 A1 Known securing device has at least one locking mechanism, with which the position of the first guide means and the second guide means to each other determined and / or the position of the second guide means and the third guide means to each other can be determined, so that the position of the guide means neither under load nor due of gravity can change. However, the securing device is constructed so that when fully retracted securing device, ie when the third guide means is inserted into the second guide means and the second guide means is inserted into the first guide means, neither the second guide means to the first guide means, nor the third guide means to the second guide means determined by a locking mechanism. Since both the second guide means and the third guide means in the lowermost position abut against a stop, an adjustment due to gravity or a load by a downward pressure is not possible.

However, it has now been shown that in completely inserted safety device in special situations it may happen that a user of the bed to find hold on an upper end of the securing device and thus at least indirectly on the third guide means and / or the second guide means , The third and / or second guide means can thereby set in motion, whereby the stop-seeking user finds no support and otherwise gain hold. That's it Risk of falling not excluded. To prevent inadvertent removal of the fuse arrangement, means could be used as shown in the documents EN 20 2015 105 365 U1 and DE 20 2015 105 367 U1 are known. However, the solutions disclosed there are complex and therefore not convenient.

The invention was therefore based on the second object to improve a fuse arrangement so that unintentional removal of the fuse arrangement is not possible.

This second object is achieved in that the first guide means and the second guide means an arrangement for securing a bed occupant against falling out of a bed, in particular a nursing bed, in a maximum retracted position of the second guide means and the second guide means and third guide means in one maximum retracted position of the third guide means are detectable with the locking mechanism. Due to the fact that the locking mechanism can be used to secure the securing arrangement against unintentional removal even in the retracted position, in the case of a securing arrangement according to the invention an unintentional removal is no longer possible with a load upward.

The locking mechanism of a securing arrangement according to the invention may comprise at least one bolt and at least one counterpart to the bolt, which serve for fixing the second and / or third guide means of the retracted securing arrangement.

In the maximum retracted position of the third guide means, the latch of the locking mechanism with one of the counterparts of the locking mechanism for detecting the first Guiding means and the second guide means to each other and / or the position of the second guide means and the third guide means cooperate with each other.

The securing arrangement may comprise a lifting means, with the determination of the first guide means and the second guide means to each other in the maximum retracted position of the second guide means and / or the determination of the second guide means and the third guide means to each other in the maximum retracted position of the third guide means are repealed can. This canceling means is advantageously coupled to the locking mechanism.

In the German utility model applications DE 20 2015 105 365 and DE 20 2015 105 367 Solutions are known, as can be prevented by means of a separate locking device with a lock or a lock integrated in a security arrangement that the second guide means from the first guide means and / or the third guide means can be pulled out of the second guide means. This may be necessary to prevent the bed occupant from being prevented from leaving the bed by removing all the securing arrangements of a bed by an unauthorized person and thus being fixed.

That in the application DE 20 2015 105 367 The lock disclosed and incorporated in the safety device prevents parts of the safety device from being pulled apart by sliding a bolt through the guide means which prevents the guide means from being removed. This is possible only in one position of the guide means to each other, namely in the maximum retracted position of the third and the second guide means. The By the way, lock is arranged on one side of the bed, which is readily visible. This does not contribute to a homely and appealing exterior of the bed.

The invention was therefore the third object to improve a fuse arrangement so that a withdrawal of the fuse assembly can be prevented by simple means, these means are not possible in the immediately visible range.

• die Sicherungsanordnung ein Blockiermittel aufweist, mit dem eine Betätigung des Aufhebemittels durch einen Benutzer blockierbar ist

oder

• die Sicherungsanordnung ein Entkoppelungsmittel aufweist, mit welchem eine Betätigung des Aufhebemittels von dem Feststellmechanismus entkoppelbar ist.

This object is achieved in that

• the securing arrangement has a blocking means with which an actuation of the lifting means can be blocked by a user

or

• the securing arrangement has a decoupling means, with which an actuation of the canceling means can be decoupled from the locking mechanism.

By blocking or decoupling, by which an action of the canceling means is prevented from acting on the locking mechanism, can be effectively prevented in a simple way changing the position of the guide means to each other. The blocking means or the decoupling means are preferably arranged in the immediate area of the canceling means. The blocking means or the decoupling means can thereby be provided in particular in a region in which a user acts on the canceling means in order to actuate it.

It is possible that the canceling means by means of the blocking means in each position of the first guide means and the second guide means to each other and / or the second guide means and the third guide means to each other, in which at least a latch of the locking mechanism and at least one counterpart to the latch cooperate for locking, can be blocked. Thus, unlike the solutions described in the earlier applications, it is possible to block the withdrawal or retraction of the securing device in any position of the guide means relative to one another and not only in the maximum retracted position.

The blocking means of a securing arrangement according to the invention may comprise a blocking element which can be moved relative to the canceling means between two end positions, wherein in the first end position the canceling means is freely movable and in the second end position, the blocking means prevents movement of the canceling means. The blocking element may be a bolt, which is displaceably mounted in its longitudinal direction preferably on the canceling means or on the first guide means, on the second guide means or on the third guide means. For moving from the first end position into the second end position, the bolt can initially be displaced linearly in its longitudinal direction into an intermediate position and then displaced from the intermediate position into the second end position by rotation about its longitudinal axis.

The blocking means or the decoupling means may comprise a lock and a key. The blocking means may be arranged such that the blocking and / or releasing of the canceling means can be actuated only by means of a key-operated closing operation, or the decoupling means may be arranged such that the decoupling and / or coupling of the canceling means from the locking mechanism is effected only by means of a locking mechanism can be actuated by the key closing process.

In the known from the prior art safety arrangements with telescopic rail guides the locking mechanisms are designed so that they have a bolt and at least one counterpart to the bolt, which serve to establish. The latch is then arranged, for example, on the third and / or second guide means movable transversely to the first direction and can be inserted by a movement transversely to the first direction in the counterpart. Due to the positive connection between the bolt and the counterpart movement between the guide means is then prevented. A counterpart to the bolt is one of the guide means, are provided in the recesses into which the bolt engages. These recesses are usually designed as through holes, which means that you can recognize the recesses at least in an extended position of the fuse assembly and may possibly also receive protection in the extended position, which complicates the complete cleaning and disinfection of the bed.

The invention was therefore based on the fourth object to improve a safety arrangement so that the exterior of the bed is as free as possible of recesses and other structures that receive a latch of the locking mechanism.

This object is achieved in that the locking mechanism has at least one rod, wherein the rod is arranged in a channel formed by the first guide means of the first guide means and / or in a second guide means formed by the second guide means and on or in the or Rods are provided the counterparts to the bolt.

The rod or rods may have recesses or projections which form the counterparts to the latch. The rod may be arranged in the at least one second guide means. The rod can form a monolith with a holder for the first wheel, a second wheel or gears of the gear transmission.

The first guide of the document EP 2 052 707 A1 known fuse arrangement has a cross-sectionally part C-shaped profile and thereby forms a channel. The second guide means is arranged linearly displaceable in the channel formed by the C-shaped profile. The C-shaped channel makes it possible for two second guide means, which are interconnected by one or more crossbars, to be displaceably arranged in the first guide means. At least in the completely inserted state of the securing arrangement, the cross members pass through the slots of the first guide means.

In particular, due in particular to improper force when using the securing arrangement, it may happen that the slot formed by the C-shaped profile is bent. Below this, the guide of the second guide means in the first guide means may suffer: The second guide means can then no longer be guided well by the first guide means, with the result that the telescopic rail guide can rattle or tilt.

The invention was therefore based on the fifth object to improve a safety arrangement so that a bending of the first guide means is prevented.

• an einem Schlitz des C-förmigen Profils des ersten Führungsmittels Ansätze vorgesehen sind, die in den durch das C-fömige Profil gebildeten Kanal ragen und
• das zweite Führungsmittel, welches in dem Kanal des ersten Führungsmittels verschiebbar angeordnet ist, auf einer Außenseite Rillen hat, in welche die Ansätze mittelbar oder unmittelbar eingreifen.

This object is achieved in that

• At a slot of the C-shaped profile of the first guide means lugs are provided which protrude into the channel formed by the C-shaped profile and
• the second guide means, which is arranged displaceably in the channel of the first guide means, has grooves on an outer side, in which the projections engage directly or indirectly.

A simple and uncomplicated operation of the fuse arrangement requires that the telescopic rail guide without tilting or the like can be pulled out and inserted. This requires that the guide means are precisely matched. For this purpose, care must be taken when manufacturing the guide means that the intended dimensions are met.

In addition, the invention has the sixth object to improve a securing arrangement so that the interaction of the guide means works even better, especially if once a guide means should not be made quite as accurate as is usually the case.

This object is achieved in that the telescopic rail guide least one sliding bush has, which is arranged between the first guide means and the second guide means or between the second guide means and the third guide means.

The slide bushing may include a tab disposed between a wall of the first guide means and a wall of the second guide means or a wall of the second guide means and a wall of the third guide means. Then in can the wall of the first guide means and the second guide means may be provided a threaded bore into which a threaded pin or another screw is screwed, the or the tip of which rests against the tab. By choosing the screwing depth of the screw, in particular the threaded pin, it can be determined whether and how far the tab is bent inwards or outwards. This makes it possible to reduce or enlarge the inner free cross-section of the sliding bushing. The inner free cross section of the slide bushing can be adapted to the dimensions of the part guided by the slide bushing part of the telescopic rail guide, namely the second guide means or the third guide means.

The from the document EP 2 052 707 A1 known fuse arrangement is designed so that it can be covered by an outside with a side cheek. For this purpose, through holes are provided in the side walls of the first guide means, which make it possible to screw a side cheek to the first guide means. One of the through holes, namely one on the inside of the securing arrangement serves only to pass the screw for fastening the side cheek and a screwdriver for screwing this screw through the inner side wall and the inside of the first guide means. This through-hole remains exposed after attachment of the side cheek to the securing arrangement, allowing dirt to penetrate into the interior of the first guiding means, which is undesirable.

The invention was therefore based on the seventh object of improving a securing arrangement such that a side cheek can be fastened to the securing arrangement without having to do so Openings in one of the guide means are necessary, can penetrate through the dirt into the interior of the guide means.

This object is achieved in that the first guide means comprises at least one tab on which a side cheek is attached or can be fastened.

This tab can have a recess for fastening the side cheek, through which a screw can be guided, with which the side cheek can be screwed to the first guide means. If the side cheek is attached to the tab of the first guide means, it is not necessary to provide holes in side walls of the guide means through which dirt can penetrate into the interior of the guide means.

Many care facilities use bed-exit alarm systems. A bed-exit alarm system can be used to detect that a bed-occupier is leaving his bed. A whistle-blower can then rush to help the bed-in person, if it is known to be in need of help, because of the bed-exit alarm triggered by leaving the bed. However, a bed-exit alarm can also turn on lights in the room where the bed is located, illuminating the room so that the occupant of the bed can safely move around the room.

Known bed-exit alarm systems are often based on weight monitoring either directly in bed or in a mat lying on the floor in front of the bed. However, weight monitoring can often lead to false alarms if the weight suddenly changes due to other causes. It is therefore desirable to have the result of weight monitoring by a second system for bed-exit monitoring can be confirmed or if the weight-based system for bed-exit monitoring can be replaced by a system that is independent of weight fluctuations.

The invention was therefore the eighth object of improving a fuse arrangement so that with the fuse arrangement, a bed-exit monitoring is possible.

This object is achieved in that the securing arrangement comprises a sensor with which the position of the first guide means and the second guide means to each other can be detected. With the solution according to the invention, it can be monitored whether a safety arrangement is or will be completely or partially inserted. In a bed occupant who is secured by the security device against falling out of the bed, then by inserting the fuse arrangement, a bed exit alarm can be triggered, which causes a caregiver to look for the bed occupant.

An inventive securing arrangement described above may comprise one or more eccentric levers, with the aid of which the securing arrangement can be fastened to a support or a frame of a bed.

• die wenigstens zwei Teleskopschienenführungen aufweist, nämlich eine erste und eine zweite Teleskopschienenführung,
• wobei die erste und die zweite Teleskopschienenführung parallel und mit einem Abstand zueinander angeordnet sind,
• wobei das zweite Führungsmittel der ersten
  Teleskopschienenführung und das zweite Führungsmittel der zweiten Teleskopschienenführung über wenigstens eine Traverse miteinander verbunden sind,

From the document EP 2 263 632 If a fuse arrangement is known,

• which has at least two telescopic rail guides, namely a first and a second telescopic rail guide,
• wherein the first and second telescopic rail guides are arranged parallel and at a distance from each other,
• wherein the second guide means of the first
  Telescopic rail guide and the second guide means of the second telescopic rail guide are connected to each other via at least one crosspiece,
• wherein the fuse arrangement a
  Motion transmitting means comprising a shaft which extends in or along the cross member from a second guide means to the other and in a movement between the first guide means and the second guide means of one of the two telescopic rail guides for transmitting the movement to the guide means the other of the two telescopic rail guides rotates.

According to the invention, it is possible that such a fuse arrangement is designed according to one of the aforementioned inventions.

According to the invention, a securing arrangement, in particular one of the aforementioned securing arrangements according to the invention, can have a drive, in particular a motor, which drives the shaft indirectly or directly. By means of this drive, the fuse arrangement can be pulled or pushed without any special effort of an operator, in particular a bed passengers. This is especially beneficial for people with physical disabilities.

A securing arrangement according to the invention can be provided on a bed, in particular on a nursing or hospital bed. The bed may have at least one securing arrangement on a first side of the bed, on a second side of the bed, at the head end and / or at the foot end. It is possible that the bed at the first and / or the second side of the bed each have a securing arrangement or each having two fuse arrangements. If two securing arrangements are provided on one side of the bed, it is possible for one of the two securing arrangements to be provided approximately at one end of the bed facing the head end and the other of the two securing arrangements approximately at a half of the bed facing the foot end. But it is also possible that a fuse arrangement according to the invention extends over more than half of a bed side, for example, to 2/3 or ¾ of a bed side. If only one securing arrangement is provided per bed side, it is preferably arranged in a part of the bed which faces the head of the kitchens. In principle, the securing arrangement can also extend over an entire side of the bed.

The in the FIGS. 1 to 11 shown first securing arrangement has two telescopic rail guides, each having a first guide means 1, a second guide means 2 and a third guide means 3.

The first guide means 1 are aligned parallel to each other and spaced from each other.

The first guide means 1 have slots on the sides facing each other. This results in that the first guide means 1 have a cross-sectionally substantially C-shaped profile. In principle, it is also possible that the first guide means have a closed hollow profile. In both cases, the first guide means form a channel.

On in the use position upper end of the first guide means 1, a first sliding bush 12 is provided. The first sliding bush 12 is seated substantially on the upper end of the first guide means 1. Tabs 121 of the sliding bush 12 are inserted into the first guide means 1. About screws 17 which are screwed through the first sliding bush 12 in screw channels of the first guide means 1, the first sliding bush 12 with the first Guiding means 1 connected. In the region of a tab, a threaded bore is provided in a side wall of the guide means 1. In this threaded hole a threaded pin 13 is inserted. By choosing the screwing depth of the threaded pin 13, the tab can be pressed more or less inward. This makes it possible to adjust the guide of the second guide means 2 by the sliding bush 12.

Due to the C-shaped profile of the first guide means 1, the first guide means on a web and two legs. At each end of each gift facing away from the web, the first guide means 1 each have a projection 101. These approaches have a cross-sectional in wesent L-shaped profile. They connect to the free ends of the legs and are each angled from the leg to which they first connect to the opposite leg then inwardly into the interior of the channel formed by the first guide means 1.

At each of the two first guide means 1, a tab 11 is provided, which is attached to the other side of the first guide means 1 side facing the outer side wall of the first guide means 1. These tabs 11 each have two holes 111 through which screws can be passed in order to screw a side cheek to the first guide means can.

In each channel of the first guide means 1, a second guide means 2 is arranged displaceably. However, securing arrangements according to the invention are also possible in which the second guide means 2 is displaceably arranged on the first guide means 1. The first guide means must then neither an im Cross-section C-shaped, still a hollow profile. There are also other profile shapes possible.

On an outer side of each second guide means 2, two parallel grooves 201 are provided in the longitudinal direction. In these grooves engage at least indirectly, the free ends of the cross-sectionally L-shaped projections of the first guide means 1 a. This prevents that the cross-sectionally C-shaped first guide means 1 is bent by loads during use.

Also in the use position upper end of the second guide means 2, a sliding bush, namely a second slide bushing 30 is provided. The sliding bush 30 is seated substantially on the upper end of the second guide means 2. Tabs 301 of the sliding bush 30 are inserted into the second guide means 2. In the region of a tab 301, a threaded bore is provided in a side wall of the second guide means 2. In this threaded hole a threaded pin 31 is inserted. By choosing the screwing depth of the threaded pin 31, the tab can be pressed more or less inward. This makes it possible to adjust the guide of the third guide means 3 by the sliding bush 30.

The second guide means 2 are connected to each other in the first securing arrangement via a first cross member 7 and a second cross member 8. The first traverse and the second traverse are preferably arranged parallel and at a distance from each other. Preferably, they are attached to an upper and a lower end of the second guide means. While the second cross member 8 in each extended state of the securing arrangement through the slots of the first guide means. 1 are guided, this is the case with the first traverse 7 at least in an inserted state of the fuse arrangement.

The second guide means 2, the first cross member 7 and the second cross member 8 form a unit which is displaceable relative to the first guide means 1.

The second guide means 2 may be closed hollow sections, which form a channel, or else in cross-section differently shaped profiles.

In each channel of the second guide means 2, a third guide means 3 is arranged displaceably. However, securing arrangements according to the invention are also possible in which the third guide means 3 is displaceably arranged on the second guide means.

The not guided in the second guide means 2 ends of the third guide means 3 are connected via a third cross member 9 and / or a handrail 10 with each other.

The third guide means 3 together with the third cross member 9 and the handrail 10 form a unit which is displaceable relative to the unit consisting of the second guide means 2, the first cross member 7 and the second cross member 8.

The outer shape of the first securing arrangement is essentially determined by the first guiding means 1, the second guiding means 2, the third guiding means 3, the first traverse 7, the second traverse 8, the third traverse 9 and the handrail 10.

The first securing arrangement has a synchronization mechanism per telescopic rail guide, which synchronizes a displacement of the first guide means to the second guide means or vice versa and a displacement of the second guide means to the third guide means and vice versa in the first direction and in a direction opposite to the first direction.

Each of these synchronization mechanism exhibits in the in the Fig. 3 illustrated variant depending on a gear transmission 14. The gear transmission 14 are spur gear. Each gear transmission 14 is disposed between a first carrier 151 and a second carrier 19. On each first carrier 151 are for this pin, on which gears 141, 142 are arranged, or provide holes in which axes of gears 143, 144, 145, 146, 147 are arranged. Holes for the axes of the gears and for the ends of the pins are provided on the second carrier. The first carrier 151 and the second carrier are arranged at a distance from one another, which is dimensioned such that the gears 141 to 147 are rotatably mounted between the two carriers 151, 19. The first and the second carrier 151, 19 together form a carrier pair. The carrier pair 151, 19 could also be referred to as a cassette which supports the gears 141 to 147. The cassette is in the Fig. 20 and 21 shown.

Each cassette 151, 19, 141 to 147 is disposed in one of the second guide means. The gears 141 to 147 are arranged so that their axes or the pins on which the gears are arranged perpendicular to a plane passing through the second guide means 2 and the first and the first and the second traverse 7, eighth is spanned. Between the carriers 151, 19 and the interposed gears 141 to 147 and the inside of the side walls of the second guide means is thereby provided a gap into which the third guide means can be inserted.

The first of these gears 141 of each pinion gear 14 and a second of these gears 142 have a larger diameter than the other gears 143, 144, 145, 146, 147 disposed between the first gear 141 and the second gear 142. However, it is not mandatory that the first gear and the second gear 141, 142 have a larger diameter. With the exception of the first gear 141 and the second gear 142, the gears 143, 144, 145, 146, 147 mesh two adjacent gears 143, 144, 145, 146, 147, respectively. The first and second gears 141, 142 each mesh a gear , The transmission 14 is designed so that the first and the second gear always rotate at the same speed and in the same direction.

In addition to the gear transmission 14, the synchronization mechanism has a first rack 16 and a second rack 17. The first rack 16 is provided in the first guide means 1 and fixedly connected thereto and the second rack 17 is provided in the third guide means 3 and fixedly connected thereto. The first rack 16 and the second rack 17 are arranged relative to the axes of rotation of the gears 141 to 147 on different sides. When the gears 141 to 147 are rotated, the first and second gears 141, 142 rotate in the same rotational direction and at the same speed, but they roll in different directions on the first rack 16 and the second rack 17.

When the first gear 141 rolls up on the first rack 16, the second gear 142 rolls on the second rack 17 downward. The first rack 16 and the second rack 17 and the associated first guide means 1 and the third guide means 3 then move apart. The telescopic guides and the securing arrangement are then extended.

When the first gear 141 rolls down on the first rack 16, the second gear 142 rolls up on the second rack 17. The first rack 16 and the second rack 17 and the associated first guide means 1 and the third guide means 3 then move toward each other. The telescopic guides and the securing arrangement are then retracted.

When in the Fig. 3.1 In the variant shown, the synchronization mechanism is achieved by a pair of wheels 41, 42 coaxial with the first gears and a closed belt 43 placed around it, which is held tight by a tensioning mechanism 44.

About a locking mechanism, a movement of the guide means 1, 2, 3 and thus a withdrawal or insertion of the telescopic rail guide and the fuse arrangement can be prevented. The locking mechanism comprises for this purpose a rod 152, which forms a monolith in the first securing arrangement together with the first carrier 151 for the gears 141 to 146 of the gear transmission 14. Thus, the rod 152 is also part of the cassette, which in the Figures 21 . 22 is shown. However, the rod 152 and the first carrier 151 could also be separate from each other.

The rod 152 is arranged in the second guide means 2 like the first carrier 151. In contrast to the carriers 151, 19 and the gear wheels 141 to 146 mounted therebetween, the rod is arranged in the second guide means 2 such that the rod 152 lies outside the third guide means 3 when the third guide means 3 is inserted into the second guide means 2 the carriers 151, 19 and the gears 141 to 146 immersed in an inserted third guide means in the third guide means. The rod 152 is then arranged between the second guide means 2 and the third guide means 3.

The rod 152 has a plurality of recesses 1521 lying on a line in the direction of extension of the second guide means 2 (see in particular FIG Fig. 3 and Fig. 5 ). In addition to the rod 152, the locking mechanism comprises a bolt 18. This bolt 18 is mounted at the lower end of the third guide means 3 in the transverse direction to the direction of displacement of the third guide means 3 relative to the second guide means 2. The bearing for the bolt is provided on an end piece 20 which is provided at the lower end of the third guide means 3. The end piece 20 is in the Fig. 22 shown. The warehouse is in the Fig. 22 designated by the reference numeral 201.

If the latch 18 mounted at the lower end of the third guide means 3 engages in a recess of the rod 151 fastened to the second guide means 2, the third and the second guide means 3, 2 can not be displaced relative to one another. The third and the second guide means 2, 3 are then fixed to one another. Since the first and the second guide means 1, 2 can be displaced via the synchronization mechanism only in synchronism with a displacement of the second to the third guide means 2, 3, are also the first and the second guide means 1, 2 found each other.

Since the rod 151 has a plurality of recesses into which the bolt 18 can engage, locking in different positions of the guide means 1, 2, 3 relative to each other is possible.

The detection can only be canceled by the fact that the latch 18 is pulled out of the recess 1521, in which it engages.

The latch 18 can be pulled out by means of a Aufhebemittels 21 from one of the recesses 1521 in the rod 152 so that the guide means 1, 2, 3 can be moved against each other. The bolt has to a recess which is penetrated by a slider 211 of the lifting means 21. The slider 211 is inclined to the direction of displacement of the guide means 1, 2, 3 and acts on a movement of the slider in the direction of displacement of the guide means as an inclined plane on the bolt 18 which is thereby displaced and in particular lifted out of a recess 1511. The slider is disposed at a lower end of a rod 212 which extends the length of the third guide means. At the upper end of the rod, a handle 213 is provided. This handle 213 has an engagement surface on which a user can engage to pull the canceling means 21 against the pressure of a spring 22 upwards. The spring 22 is supported on the one hand on the rod 212 and on the other hand on the upper of the third guide means 3, namely on an underside of the third cross member 9 from.

The operation of the canceling means 21 can be prevented by means of a blocking means 23. This can prevent the guide means 1, 2, 3 from being displaced relative to each other become. An extension or insertion of the fuse arrangement is thereby prevented. The blocking means 23 has a bolt 231 as a blocking element, which is displaceably mounted on the handle 213 in its longitudinal direction. The handle 213 has for a channel as a guide. The pin 231 has a transverse bore in which a pin 232 is inserted the pin 232 projects beyond the pin 231 side. The channel in the handle has a first groove in which the protruding end of the pin 232 is guided in a displacement of the bolt 231. Between the bolt and the underside of the third cross member 9, a spring 24 is arranged, which presses the bolt in a lower first end position. Against the pressure of the spring 24, the bolt can be moved until the pin 231 abuts against the underside of the third traverse 9. The pin 231 can then be rotated so that the projecting end of the pin 232 merges into a second groove in the handle 213 extending at a right angle to the first groove. If the protruding end of the pin has come into the second groove by the rotation of the bolt, the bolt 231 can not be moved in its longitudinal direction. If it is turned in the second groove to a stop, the bolt 231 has reached a second end position. From this second end position, the bolt 231 can not be moved by the pressure of the spring 24 in the first end position alone. For this purpose, it is necessary to rotate the bolt about its longitudinal axis, so that the protruding end of the pin 232 comes into the region in which the first groove and the second groove are connected to each other.

The bolt 231 has a key surface which is adapted to be rotated by means of a key 233 of the blocking means. By means of the key 233, a torque can be transmitted into the bolt 231 to move the bolt 231 from the second or to the second end position by the rotation in order to release or block the canceling means.

At a lower end of the first guide means, a sensor 24 is provided which can determine the position of the second guide means 2 to the first guide means by means of a measuring method not described in detail. The sensor 24 is connected via a cable 241, which is guided by a cable gland 242, with an evaluation unit, not shown.

The securing arrangement according to the invention can in particular be fastened to a side member of a bed. For this purpose, the securing arrangement on a C-shaped bracket 25 which is fastened with screws to the first guide means 1. The console is attached to a web 251 to the first guide means 1, while legs 252 of the console engage around the side rail of the bed. At the free ends of the legs 252 aligned bores are provided, through which a screw 26 is guided, which is secured by a nut 27. On the screw 26 and between the legs 252, an eccentric lever 28 is arranged. By a rotation of the eccentric lever, a clearance between the screw 26 and the side member can be reduced to zero.

In a fuse arrangement according to the invention, as in the second fuse arrangement according to the FIGS. 12 to 19 As shown, the movement of the guide means 1, 2, 3 of one of the two telescopic rail guides can be transmitted by a motion transmission means 29 to the guide means 1, 2, 3 of the other of the two telescopic rail guides. The second fuse arrangement, with the exception of the motion transmission means 29, corresponds to the first fuse arrangement. The motion transmission means 29 are additionally provided.

The movement transmission means 29 comprise a third and a fourth rack 291, 292. Each of these racks is mounted on the inside of one of the tabs 11 of the first guide means 1. Each of the racks 291, 292 is combed by a gear 293, 294. These gears have a same diameter and a similar toothing, as well as the third and the fourth rack 291, 292 have a similar toothing. The two gears are connected to each other via a shaft 295, so that the rotation of the one gear 293 is transmitted to the other gear 294 and vice versa. By the motion transmission means 29, a pull-out or push-in movement is transmitted from one telescopic rail guide to the other telescopic rail guide. As a result, the two telescopic rail guides are always in synchronism, whereby tilting of the guide means 1, 2, 3 is prevented when only on one side of the fuse assembly, the force for inserting or removing the fuse assembly is applied.

The shaft 295 or one of the gears 293, 294 may be coupled to a motor (not shown). With such a motor, the fuse assembly can be extended and retracted by a motor.
