Definitions

  • the invention relates to a locking device for at least one Lattice brace formed side grille of a bed, in particular a patient and / or Care bed.
  • Beds especially hospital and / or nursing beds, have side rails, which are arranged alongside the bed and between the bed frame end pieces are fixed. Such side rails serve primarily to lay in bed To prevent the person from accidentally falling out of bed.
  • a side rail for beds in particular for sick and / or nursing beds, disclosed for example, DE 201 12 069.
  • a side rail is shown here, which consists of at least one lattice strut and a connecting element for preference releasable arrangement of the lattice strut on the bed.
  • the detachable arrangement of the Lattice brace is required to keep the patient or whoever is in the Want to put the bed in, to make it easier to get into the bed.
  • the side rail for a convenient entry into the Bed is adjustable or detachably arranged on the bed, in any case ensure that the side rail in its end position corresponds to the person lying in bed secures against falling out of bed, whereby an unwanted loosening or The side rail must not be moved.
  • State of the art locking devices used in or on Side rails or the side rail struts are arranged and a simple Move the side rail from its end position to the entry position should bring about.
  • a disadvantage of the known locking systems is the fact that these are arranged directly on the side rail itself, which means that the Side rails must be designed accordingly robust. On the one hand, this limits the Material selection for the side rail, on the other hand it is due to the resulting side rail weight of a high effort to the Release the lock and the side rail in the desired position spend. It should also be borne in mind that the side rail and thus also the Locking device due to frequent entering and exiting the bed are exposed to high mechanical stress.
  • the usage Known locking devices are due to the high weight of the Side rails mostly complex and complex, one not properly performed locking of the side rails due to the repeatedly occurring high mechanical load serious safety deficiencies can cause, because an incorrectly secured side rail can be Security function does not do justice.
  • the object of the invention is therefore, while avoiding the above Disadvantages of providing a locking device that is safe and secure Locking the side rail with simpler at the same time Unlocking option allowed.
  • the locking device should be such be designed that a variety of different materials for the side rails are usable.
  • Locking device for one formed from at least one lattice strut Side rails of a bed, especially a hospital and / or nursing bed proposed which a locking element and an at least partially has a sliding element corresponding to the locking element, wherein the locking element is stationary on the bed and the sliding element relative to Locking element are arranged movably on the lattice strut.
  • the locking device is provided, wherein a part of the Locking device, namely the locking element, stationary on the bed, preferably at the end of the bed, and the other part of the locking device, namely the sliding element on which the lattice strut is arranged.
  • the sliding element is arranged movable relative to the locking element, so that the Move the lattice strut together with the sliding element relative to the locking element and can thus be moved from an entry position to an end position.
  • the end position of the lattice strut also called the closed position, this forms Locking element and the sliding element a force-transmitting unit and thus secure the lattice strut in its position in a simple manner.
  • the above-described configuration of the locking device also offers the advantage that now a much larger number of different Materials for the side rails or the strut can be used because Fittings or other holding devices on the side rail or the mesh strut themselves are no longer required.
  • Another significant advantage of the locking device according to the invention is easier and safer thanks to the secure and firm locking Unlocking option given.
  • This is achieved in that the Sliding element by simply pulling up or pushing the lattice strut in the closed position can be moved.
  • the sliding element Closure position reached is at least partially corresponding to the trained locking element formed a force-transmitting unit, which an unwanted moving back of the sliding element and thus the Lattice strut prevented.
  • the lattice strut is therefore fixed in its position and can cannot be solved unintentionally.
  • To remove the lattice strut if necessary To move the locking position, it is only necessary that To release locking element and the sliding element from each other and that To release the sliding element again, so that it moves together with the lattice strut can be.
  • the locking element is designed to be resilient in the manner of a leaf spring and arranged in a recess on the bed end piece.
  • the connecting element has a holding means designed as a projection, the in the closed position of the locking element and sliding element in a Recessed slide element protrudes.
  • the holding element in turn has a barb-shaped extension which in the closed position of Locking element and sliding element one in the recess of the Undercut provided sliding element engages behind.
  • the sliding element moves from a non-closed position into the closed position brought the locking device, so it slides on the stationary end of the bed arranged locking element over. In the course of this gliding past the locking element arranged on one side of the bed end piece is resilient pushed aside.
  • the holding means of the Locking element on its facing away from the barb-shaped extension Page a guide contour, which together with the sliding element in the manner of a Interacts cam arrangement. Is the sliding element then as far as Locking element passed that that formed as a projection Snap the holding element into a recess provided in the sliding element can, the locking element springs back and presses the holding element into the mentioned recess in the sliding element. That in the recess of the Preventing sliding element of the locking element protruding an unwanted sliding back of the sliding element in the starting position, as it rests on the holding element and is held by it.

It is not required the lattice strut as a whole, d. H.
  • both ends of the lattice strut in only to move it into the desired position with a single move.
  • This on the one hand opens up improved ease of use, on the other hand here due to the mechanical load on the lattice struts, which is caused by an adjustment the same can be reduced, since both ends are independent of each other can be moved to the desired position in a simple manner.
