Embodiment Construction

[0024] figure 1 A castor 1 is shown with a mounting pin 2 having a vertical axis of rotation 3 about which the castor 1 can turn. The castor 1 comprises a set of wheels 4 , 5 rotatable about a horizontal axis 6 . The brake actuator 7 is arranged above the wheels 4 , 5 and can be set in three different positions by pivoting up and down about the axis 9 as indicated by the arrow 8 . Such as figure 2 As shown, in the upper position 10 (direction locked), the castor 1 is locked in a given direction 11 . This means that the wheels 4, 5 are free to rotate, but the mounting pin 2 is locked in the preferred orientation. This allows the castor 1 to travel along the surface in direction 11 . If the brake actuator 7 is set in the down position 12 (braked), the castor 1 will be fully locked or braked. This means that the castor 1 cannot rotate about the vertical axis 3 of the mounting pin 2 and the wheels 4 , 5 cannot rotate about the horizontal axis 6 . Thus, the castor 1 is not m...

Abstract

A system for controlling at least two castors (1) in a castor control system (28) is provided. The castor comprises a brake activator (7) which can be used to set the castor (1) in three different positions: directional lock, neutral or braked. The brake activator (7) can be operated manually, e.g. by foot, or via a servo motor assembly (14) having a servo motor connected to the brake activator of the castor. The servo motor assembly further comprises a printed circuit board (16), a microprocessor (17) and at least one switch (19,20) connected to the brake activator (7). The servo motor assembly can further comprise a motion sensor (18). The servo motor assembly of each castor is connected to an electric brake controller (33) of the castor control system. The castors can be operated from an operating panel (37) of the castor control system (28). If the brake activator (7) of one castor is manually operated, the electric brake controller (33) can be set to let one or more of the other castors of the system assume the same position. The system can also set all castors (1) in the braked position if the motion sensor (18) detects motion of the castors (1) and the system is connected to mains voltage (40).

Description

technical field [0001] The present invention relates to a castor control system and a method for operating the system. Background technique [0002] Casters typically include a fork from which mounting pins project vertically. In the fork, a running wheel is mounted via a horizontal shaft. The fork is rotatable about the vertical axis of the mounting pin and the wheel is rotatable about the horizontal axis of its mounting shaft. When installed in hospitals and care facilities, casters are usually fitted with means for locking the rotation and means for braking the wheels. These devices can be used alone or in combination. GB2457787 of Oy Mannerin Konepaja AB describes such a castor. [0003] In hospital beds, braking and locking devices are usually interconnected mechanically so that they can be operated via pedals. Such a bed is disclosed in EP618088A2 to Hill-Rom. A further development of this principle is described in EP1945166A2 of LINETSPOL S.R.O. Here, the under...
