Definitions

  • the invention relates to a height-adjustable side rail system for a bed frame, comprising a first frame element with two first adjustment elements adjustable in the longitudinal direction of the first frame element and spaced apart from each other, and a second frame element spaced apart from the first frame element with two second adjustment elements adjustable in the longitudinal direction of the second frame element and spaced apart from each other.
  • the side rail system has two lever systems connecting the frame elements and spaced apart from each other in the longitudinal direction of the frame elements.
  • the invention relates to a bed frame with a head unit, a foot unit, and a lying surface arranged between the head unit and the foot unit.
  • Height-adjustable side rail systems of the type mentioned above are known in various embodiments from the prior art; see, for example, WO 01/72255 A2 They protect a person lying on the surface of a bed formed using the side rail system, e.g., a patient, from falling out of or off the bed, and, for example, as a handrail, facilitate the patient's transfer from a lying to a sitting position.
  • the bed formed using the side rail system is primarily used in medical and nursing settings.
  • the invention is based on the objective of providing a height-adjustable side rail system for a bed frame that enables simple and quick height adjustment. Furthermore, the invention is based on the objective of providing a bed frame with a lying surface that is quickly and easily accessible.
  • the invention solves the problem by means of a height-adjustable side rail system with the features of claim 1 and a bed frame with the features of claim 12.
  • Advantageous further developments of the invention are specified in the dependent claims.

"Alternating distance” here means that the distance between the second frame element and the first frame element is increased or decreased at an angle or perpendicular to the longitudinal axes of both frame elements.
  • the first articulated levers are each pivotally connected to the first adjusting elements arranged on the first frame element via the first connecting sections and to the second frame element via the first coupling sections.

  • the second frame element Through the connection via the lever systems, the second frame element is moved relative to the first frame element at an angle, preferably perpendicular to the longitudinal axes of both frame elements, towards the first frame element, thereby reducing the distance between the frame elements.

  • the side rail system With the side rail system at a greater height in the safety position, its protective effect for a person lying on the bed surface of a bed frame constructed using the side rail system, such as a patient, remains guaranteed.
  • the side rail system acts as a fall protection barrier, preventing the person being cared for from falling out of the bed frame.
  • the lower height of the side rail system in the access position allows for easy access for caregivers.

  • the locking elements 36 are pre-tensioned in a perpendicular direction to the main plane H of the side grille system 1 in the direction of the actuating element 33, so that a spring pre-tension of the actuating element 33 in the direction of the locking position is effected.
  • the operating elements 33 are moved by a user from the locked position to the released position.
  • the adjusting elements 5, 6, 7 are each adjusted relative to each other, i.e., in the longitudinal axis direction of the frame elements 2, 3, 4 between the starting position and the end position.
  • the second frame element 3 is moved relative to the first frame element 2 and the third frame element 4 relative to the first and second frame elements 2, 3 at an angle or perpendicular to the longitudinal axes L1, L2, L3 of the frame elements 2, 3, 4 and in the main plane H of the side grid system 1 of the in Fig. 4, 4a the security situation shown in the Fig. 6, 6a
  • the access situation shown is obstructed.
  • the operating elements 33 can be actuated by the user simultaneously or separately. Simultaneous actuation of both operating elements 33 enables synchronous adjustment of the first, second, and third adjustment elements 5, 6, 7, thereby aligning the longitudinal axes L1, L2, L3 of the frame elements 2, 3, 4 parallel to each other.
  • the separate actuation of the actuating elements 33 enables asynchronous adjustment of the first, second, and third adjusting elements 5, 6, 7, respectively.
  • the pivot pins 23 of the lever systems 8, 9 must be loosened, so that the pivot levers 11, 12, 13, 14 of the lever systems 8, 9 are mechanically connected to each other only via the connection to the adjusting elements 5, 6, 7 and the connection to the frame elements 2, 3, 4.
  • a protective element 38 is arranged on each of the first frame element 2 and the third frame element 4 (see below).
  • the protective elements 38 each have a cross-section extending in the longitudinal direction of the frame element 2, 4 between the frame element end faces 28. In the secured position, the protective elements 38 project into a space formed between the first and second frame element 2, 3 and between the second and third frame element 3, 4. In the access position, the protective elements 38 cover a side wall 39 of the second frame element 3.
  • connection elements arranged at intervals from each other in the longitudinal axis direction L1 of the first frame element 2 are attached to the first frame element 2.
  • the side rail system 1 is arranged in the form of C-shaped clamping elements 40 on a lying surface 41 of a bed frame 42.
  • the clamping elements 40 are fixedly arranged on the first frame element 2 via a screw connection and can be connected to the lying surface 41 via a pin element in the form of a screw 44 interacting with a nut 45.
  • the bed frame 42 shown comprises a lying surface 41, a head unit 46, and a foot unit 47 arranged at a distance from the head unit 46.
  • the lying surface 41 has a head/back segment 48 and a leg segment 49, the segments 48 and 49 being adjustable relative to each other.
  • a first side rail system 1 is arranged in the area of the head/back segment 48, and a second side rail system 1 is arranged at a distance from the first side rail system 1 in the area of the leg segment.
  • the third upper frame element 4 when attached to the bed frame 42 in its operating position, is located above the first lower frame element 2 and above the second middle frame element 3.
  • the upper and middle frame elements 3 and 4 are positioned relative to the lower frame element 2, which is fixed to the bed frame 42, between the... Fig. 9 the security situation shown and the one in Fig. 10
  • the access position shown can be moved.
  • the actuating elements 33 are therefore arranged on the upper frame element 4 with respect to the operating position.
