Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • 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
  • the tension member may be a V-belt.
  • 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.
  • 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.
  • 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 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the blocking means of a securing arrangement 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.
  • 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.
  • 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 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.
  • 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.
  • 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.
  • 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.

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.
  • 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.
  • 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.

  • 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.
  • a spring 24 is arranged, which presses the bolt in a lower first end position.
  • 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.
  • 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.
  • 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.
  • 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.
  • legs 252 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.
  • an eccentric lever 28 is arranged on the screw 26 and between the legs 252. By a rotation of the eccentric lever, a clearance between the screw 26 and the side member can be reduced to zero.
  • 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.
  • a pull-out or push-in movement is transmitted from one telescopic rail guide to the other telescopic rail guide.
  • 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.
