Abstract

A positioning mechanism of a bed comprising height adjustable lifters (1, 2, 3) that are mounted on the undercar-riage (4) and connected to the patient surface frame (5). The first lifter (1 ) is arranged that its axis intersects the longitudinal axis (6) of the frame (5) and the said lifter (1 ) is connected to frame (5) oscillatingly around the longitudinal axis (6) of the frame (5) and in a sliding way in the direction of the longitudinal axis (6) of the frame (5). The second lifter (2) and the third lifter (2) are in-terconnected with an arm (10), oriented transversally to the longitudinal axis (6). The arm (10) is oscillatingly connected to the frame (5) and is connected at one end to the second lifter (2) both oscillatingly around an axis, in parallel with the longitudinal axis (6) of the frame (5) and in a sliding way transversally to the frame (5).
At the other end the arm (10) is connected to the third lifter (3), oscillatingly around the axis, in parallel with the longitudinal axis (6) of the frame (5).

Claims (3)

1. A positioning mechanism of a bed comprising at least two height adjustable lifters (1, 2, 3) arranged in a distance from each other that are mounted on the undercarriage frame (4) at one side and connected to the patient surface frame (5) at the other side, the first lifter (1) is arranged in such a way that its axis intersects the longitudinal axis (6) of the patient surface frame (5) and the first lifter (1) is connected to the patient surface frame (5) in a swinging way around the longitudinal axis (6) of the patient surface frame (5) and in a sliding way in the direction of the longitudinal axis (6) of the patient surface frame (5) while the second lifter (2) and the third lifter (2) are interconnected with an arm (10), oriented transversally to the longitudinal axis (6) of the patient surface frame (5) and the arm (10) is connected to the patient surface frame (5) in a swinging way while the arm (10) is connected at one end to the second lifter (2) both in a swinging way around the axis, in parallel with the longitudinal axis (6) of the patient surface frame (5) and in a sliding way transversally to the patient surface frame (5) and at the other end the arm (10) is connected to the third lifter (3), in a swinging way around the axis, in parallel with the longitudinal axis (6) of the patient surface frame (5), characterized by the fact that the first lifter (1) at its top end carries at least one horizontal first guide (7) in which the first slider (8) is mounted in a sliding way and the first slider (8) is connected to a yoke (9) in a swinging way while the yoke (9) is connected to the patient surface frame (5) in a swinging way whereas the second lifter (2) carries at its top end at least one horizontal second guide (12) in which at least one second slider (11) is mounted in a sliding way that is connected with a pin (17) to one end of the arm (10) while the third lifter (3) is connected to the opposite end of the arm (10) with a pin (17).
2. The positioning mechanism of a bed in accordance with claim 1, characterized by the fact that the distance (B) between the axes of the pins (17) arranged at the opposite ends of the arm (10) is bigger than the distance (A) between the longitudinal axes of the second and third lifter (2, 3).
3. The positioning mechanism of a bed in accordance with any of the claims 1 to 2, characterized by the fact that between the undercarriage frame (4) and patient surface frame (5) position sensors (15) with an opposite cam (16) are arranged.
