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 gears meshing the racks 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 be the first rack and the second gear may mesh 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. The risk of a fall is 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, especially 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 under 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 locking the first guide 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 taking off all the security arrangements of a bed by an unauthorized person at the same time Leaving the bed is prevented and thus 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. Incidentally, the 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 fuse arrangement comprises a blocking means with which an operation of the canceling means is blocked by a user or
• - The fuse arrangement comprises 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 cooperate at least one latch of the locking mechanism and at least one counterpart to the locking bar, 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 have 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 or the decoupling means may be arranged so that the decoupling and / or coupling of the canceling means from the locking mechanism can be actuated only by means of a key closing operation.

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 fourth object, a fuse arrangement to improve 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

• - Approaches are provided on a slot of the C-shaped profile of the first guide means, which protrude into the channel formed by the C-shaped profile and
• - The second guide means, which is slidably disposed in the channel of the first guide means, on an outer side grooves, in which the approaches 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 was the fifth object of improving a safety 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 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 on 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 free after attachment of the side cheek to the fuse assembly, what allows dirt to penetrate into the interior of the first guide means, which is not desirable.

The invention therefore had the sixth object of improving a securing arrangement in such a way that a side cheek can be fastened to the securing arrangement without the need for openings in one of the guide means, through which dirt can penetrate 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 if the result of the weight monitoring can be confirmed by a second system for bed-exit monitoring or if the weight-based system for bed-exit monitoring can be replaced by a system that is independent of weight fluctuations.

The invention therefore had the sixth object to improve 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.

According to the invention, the securing arrangement may comprise a drive, in particular a motor, which drives the shaft directly or indirectly. 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 for the bed to have one securing arrangement or two securing arrangements on the first and / or the second side of the bed. Are two securing arrangements on one side of the bed provided, it is possible that one of the two securing arrangements is provided approximately at one of the head end facing half of the bed and the other of the two securing arrangements approximately at one end of the foot facing half of the bed. 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. In principle, the securing arrangement can also extend over an entire side of the bed.

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

The first guide 1 are aligned parallel to each other and have a distance from each other.

The first guide 1 have slots on the sides facing each other. As a result, it turns out 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.

Am in the use position upper end of the first guide means 1 is a first sliding bush 12 intended. The first sliding bush 12 sits essentially on the upper end of the first guide means 1 on. tabs 121 the sliding bush 12 are in the first guide 1 plugged in. About screws 17 passing through the first sliding bush 12 in screw channels of the first guide means 1 are screwed in, is the first sliding bush 12 with the first guide means 1 connected. In the area of a tab is in a side wall of the guide means 1 provided a threaded hole. In this threaded hole is a threaded pin 13 used. By choosing the screw-in depth of the threaded pin 13 The tab can be pressed more or less inward. This makes it possible to guide the second guide means 2 through the sliding bush 12 adjust.

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

At each of the first two guide means 1 is a tab 11 provided on the one another the other first guide means 1 facing side on the outer side wall of the first guide means 1 is scheduled. These tabs 11 each have two holes 111 can be passed through the screws to screw a side cheek to the first guide means can.

In each channel of the first guide means 1 is in each case a second guide means 2 slidably arranged. But it also fuse arrangements according to the invention are possible in which the second guide means 2 on the first guide means 1 slidably arranged. The first guide means must then be neither a cross-section C-shaped, nor a hollow profile. There are also other profile shapes possible.

On an outside of each second guide means 2 are longitudinally two parallel grooves 201 intended. In these grooves engage at least indirectly, the free ends of the cross-sectionally L-shaped projections of the first guide means 1 one. This prevents that in cross-section C-shaped first guide means 1 is bent up by loads during use.

Also on in the use position upper end of the second guide means 2 is a sliding bush, namely a second sliding bush 30 intended. The sliding bush 30 sits essentially on the upper end of the second guide means 2 on. tabs 301 the sliding bush 30 are in the second guide 2 plugged in. In the area of a tab 301 is in a side wall of the second guide means 2 provided a threaded hole. In this threaded hole is a threaded pin 31 used. By choosing the screw-in depth of the threaded pin 31 The tab can be pressed more or less inward. This makes it possible, the leadership of the third guide means 3 through the sliding bush 30 adjust.

The second guiding means 2 are at the first securing arrangement on a first traverse 7 and a second traverse 8th connected with each other. 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 traverse 8th in any extended state of the securing arrangement through the slots of the first guide means 1 this is at the first traverse 7 at least in an inserted state of the fuse arrangement of the case.

The second guiding means 2 , the first traverse 7 and the second traverse 8th form a unity, the first guidance means 1 is displaceable.

The second guiding means 2 can be closed hollow sections that form a channel, or in cross-section differently shaped profiles.

In each channel of the second guide means 2 is a third guide 3 slidably arranged. But it also fuse arrangements according to the invention are possible in which the third guide means 3 is slidably disposed on the second guide means.

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

The third guide 3 form together with the third traverse 9 and the handrail 10 a unit belonging to the unit of the second guidance means 2 , the first traverse 7 and the second traverse 8th is displaceable.

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

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 3 illustrated variant depending on a gear transmission 14 on. The gear transmission 14 are spur gears. Every gear transmission 14 is between a first carrier 151 and a second carrier 19 arranged. At every first carrier 151 are for it cones, on which gears 141 . 142 are arranged, or provide holes in which axles 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 each other that is dimensioned such that the gears 141 to 147 between the two carriers 151 . 19 are rotatably mounted. The first and the second carrier 151 . 19 together form a carrier pair. You could be the carrier pair 151 . 19 Also called a cassette, which is the gears 141 to 147 outsourced. The cassette is in the 20 and 21 shown.

Every cassette 151 . 19 . 141 to 147 is arranged 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 . 8th is spanned. Between the carriers 151 . 19 and the gears mounted therebetween 141 to 147 and the inside of the side walls of the second guide means, a gap is provided, in which the third guide means can be inserted.

The first of these gears 141 each gear transmission 14 and a second of these gears 142 have a larger diameter than the other gears 143 . 144 . 145 . 146 . 147 between the first gear 141 and the second gear 142 are arranged. However, it is not mandatory that the first gear and the second gear 141 . 142 have a larger diameter. Except for the first gear 141 and the second gear 142 comb the gears 143 . 144 . 145 . 146 . 147 two adjacent gears each 143 . 144 . 145 . 146 . 147 , The first and the second gear 141 . 142 each comb a gear. The gear 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 on. The first rack 16 is in the first guide 1 provided and firmly connected to this and the second rack 17 is in the third guide means 3 provided and firmly connected to this. The first rack 16 and the second rack 17 are related to the axes of rotation of the gears 141 to 147 arranged on different sides. Be the gears 141 to 147 turned, turn the first and second gear 141 . 142 Although in the same direction and at the same speed, but they roll on the first rack 16 and the second rack 17 in different directions.

If the first gear 141 on the first rack 16 rolls up, rolls the second gear 142 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.

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

When in the 3 .1 shown is the synchronization mechanism by a two coaxial with the first gears wheels 41 . 42 and a closed one placed around it belt 43 achieved by a clamping mechanism 44 is kept tight.

About a locking mechanism can be a movement of the guide means 1 . 2 . 3 and thus a telescoping or insertion of the telescopic rail guide and the fuse arrangement can be prevented. The locking mechanism includes a rod 152 used in the first securing arrangement together with the first carrier 151 for the gears 141 to 146 of the gear transmission 14 forms a monolith. This is the pole 152 also part of the cassette in the 21 . 22 is shown. The pole 152 and the first carrier 151 but could also be separated.

The pole 152 is like the first carrier 151 in the second guide means 2 arranged. Unlike the straps 151 . 19 and the gears mounted therebetween 141 to 146 the rod is so in the second guide means 2 arranged that pole 152 at one in the second guide means 2 inserted third guide means 3 outside the third guide means 3 lies while the wearer 151 . 19 and the gears 141 to 146 immerse in the third guide means at an inserted third guide means. The pole 152 is then between the second guide means 2 and the third guide means 3 arranged.

The pole 152 has on a line in the extending direction of the second guide means 2 lying several recesses 1521 (see in particular 3 and 5 ). Next to the pole 152 the locking mechanism comprises a latch 18 , This bar 18 is 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 stored. The bearing for the bolt is on an end piece 20 provided, which at the lower end of the third guide means 3 is provided. The tail 20 is in the 22 shown. The warehouse is in the 22 with the reference number 201 designated.

Attacks the at the bottom of the third guide means 3 stored bars 18 in a recess of the second guide means 2 attached rod 151 One, the third and the second guide means 3 . 2 not be moved against each other. The third and the second guide 2 . 3 are then determined to each other. Because the first and the second guide means 1 . 2 via the synchronization mechanism only synchronously a displacement of the second to the third guide means 2 . 3 can be moved, are also the first and the second guide means 1 . 2 established to each other.

Because the rod 151 has a plurality of recesses, in which the bolt 18 is able to intervene in different positions of the guide means 1 . 2 . 3 possible to each other.

An extension or insertion of the fuse arrangement is thereby prevented. The blocking agent 23 has a bolt 231 as a blocking element on the handle 213 is slidably mounted in its longitudinal direction. The handle 213 has a channel as a guide. The bolt 231 has a transverse bore in which a pin 232 The pen is inserted 232 towers over the bolt 231 laterally. The channel in the handle has a first groove in which the protruding end of the pin 232 when moving the bolt 231 is guided. Between the bolt and the bottom of the third crossbar 9 is a spring 24 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 bolt 231 at the bottom of the third travers 9 strikes. The bolt 231 can then be rotated, leaving the towering end of the pen 232 in a first groove at a right angle extending second groove in the handle 213 passes. If the protruding end of the pin has come into the second groove by the rotation of the bolt, the bolt can 231 Not be moved more in its longitudinal direction. If it is turned in the second groove to a stop, the bolt has 231 reached a second end position. From this second end position of the bolt 231 not only by the pressure of the spring 24 be moved to the first end position. For this it is necessary to turn the bolt around its longitudinal axis, leaving the protruding end of the pin 232 comes in the area where the first groove and the second groove are connected to each other.

The bolt 231 has a key surface that is designed to be keyed 233 of the blocking agent can be rotated. By means of the key 233 can be a torque in the bolt 231 be transferred to by turning the bolt 231 from the second or the second end position to release or block the canceling means.

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