Abstract

A trolley (1), for a beam-mounted supply unit, for fastening medical devices to a ceiling. The trolley has a chassis (2) which can be meshed with a rail track of the beam-mounted supply unit for moving the trolley (1) along the rail track. A medical device can be fastened to the trolley (1). The trolley has a brake unit (3) with at least one braking element (7), which exerts a braking force on the rail track and/or on the chassis in the activated state of the brake unit (3), so that a movement of the chassis along the rail track is at least made difficult compared to an operating state with the brake unit (3) deactivated. In the activated state of the brake unit (3), the braking force exerted by the braking element (7) on the rail track and/or on the chassis is generated without the aid of electric energy.

First claim

1 . A trolley for a beam-mounted supply unit for fastening medical devices to a ceiling, the trolley comprising:
a chassis, which can be meshed with a rail track of the beam-mounted supply unit for moving the trolley and which can be moved along the rail track and to which at least one medical device can be directly or indirectly fastened; a brake unit comprising at least one braking element, which exerts a braking force on the rail track an or on the chassis or on the rail track and on the chassis in the activated state of the brake unit, so that a movement of the chassis along the rail track unit is at least made difficult compared to an operating state with a deactivated brake, and an electromagnetically or mechanically or an electromagnetically and mechanically driven actuator, wherein in the activated state of the brake unit, the braking force exerted by the braking element on the rail track or on the chassis or on the rail track and on the chassis is generated without the an aid of electric energy, and that the brake unit is deactivated and the braking element is triggered by an opposing force acting against the braking force exerted on the rail track or on the chassis or on the rail track and on the chassis being generated by means of the actuator.

2 . A trolley in accordance with claim 1 , wherein in the activated state of the brake unit, the braking force exerted by the braking element on the rail track or on the chassis or on the rail track and on the chassis is generated by means of an element, which exerts a spring force and/or magnetic force.

3 . A trolley in accordance with claim 1 , further comprising at least one lever element, wherein the actuator acts on the braking element the via at least one lever element.

4 . A trolley in accordance with claim 1 , wherein the actuator comprises an electric motor or a pulling magnet or pushing magnet that can be electrically actuated.

5 . A trolley in accordance with claim 1 , further comprising an operating element, wherein the actuator can be moved by actuating the operating element.

6 . A trolley in accordance with claim 1 , wherein the braking element further comprises a brake plunger, which is pressed at least partly against the rail track or the chassis or against the rail and the chassis in the activated state of the brake unit.

7 . A trolley in accordance with claim 6 , wherein the brake plunger has at least one brake lining and a brake lining holder

8 . A trolley in accordance with claim 1 , further comprising a manually actuatable lever mechanism or a manually actuatable lever linkage wherein the actuator is connected to the manually actuatable lever mechanism or the manually actuatable linkage and can be activated by means of the lever mechanism or lever linkage.

9 . A trolley in accordance with claim 1 , wherein the brake unit further comprises a lever element, a pivot bearing and a bolt, which are in active connection with the actuator.

10 . A beam-mounted supply unit for fastening medical devices and device carriers, which are suitable for accommodating medical devices, to a ceiling of a care room, treatment room or operating room, the supply unit comprising:
a supply unit for the transmission of medical gases, compressed air, operating materials, electric energy and/or data from a hospital infrastructure in at least one medical device, at least one rail track fastened directly or indirectly to the ceiling; and a trolley that can be stopped in relation to the rail track and can be moved along the rail track during a deactivation of a brake unit based on need, wherein the trolley comprises; a chassis, which can be meshed with the rail track of the beam-mounted supply unit for moving the trolley and which can be moved along the rail track and to which at least one medical device can be directly or indirectly fastened; a brake unit comprising at least one braking element, which exerts a braking force on the rail track or on the chassis or on the rail track and on the chassis in the activated state of the brake unit, so that a movement of the chassis along the rail track unit is at least made difficult compared to an operating state with a deactivated brake, and an electromagnetically or mechanically or an electromagnetically and mechanically driven actuator, wherein in the activated state of the brake unit, the braking force exerted by the braking element on the rail track or on the chassis or on the rail track and on the chassis is generated without an aid of electric energy, and the brake unit is deactivated and the braking element is triggered by an opposing force acting against the braking force exerted on the rail track or on the chassis or on the rail track and on the chassis being generated by means of the actuator.

11 . A beam-mounted supply unit in accordance with claim 10 , wherein in the activated state of the brake unit, the braking force exerted by the braking element on the rail track or on the chassis or on the rail track and on the chassis is generated by means of an element, which exerts a spring force and/or magnetic force.

12 . A beam-mounted supply unit in accordance with claim 10 , further comprising at least one lever element, wherein the actuator acts on the braking element the via at least one lever element.

13 . A beam-mounted supply unit in accordance with claim 10 , wherein the actuator comprises an electric motor or a pulling magnet or pushing magnet that can be electrically actuated.

14 . A beam-mounted supply unit in accordance with claim 10 , further comprising an operating element, wherein the actuator can be moved by actuating the operating element.

15 . A beam-mounted supply unit in accordance with claim 10 , wherein the braking element further comprises a brake plunger, which is pressed at least partly against the rail track or the chassis or against the rail and the chassis in the activated state of the brake unit.

16 . A beam-mounted supply unit in accordance with claim 15 , wherein the brake plunger has at least one brake lining and a brake lining holder.

17 . A beam-mounted supply unit in accordance with claim 10 , further comprising a manually actuatable lever mechanism or a manually actuatable lever linkage wherein the actuator is connected to the manually actuatable lever mechanism or the manually actuatable linkage and can be activated by means of the lever mechanism or lever linkage.

18 . A beam-mounted supply unit in accordance with claim 10 , wherein the brake unit further comprises a lever element, a pivot bearing and a bolt, which are in active connection with the actuator.
