AI Technical Summary

Technical Problem

Existing adjustable beds for medical robots require a large installation space due to their complex device configuration, which includes mechanisms for rotating around both the roll and pitch axes.

Method used

A bed device with a tilting section that uses a fulcrum section supported by a spherical bearing, a first drive unit for rotating around a roll axis, and a second drive unit for rotating around a pitch axis, all arranged on a central axis passing through the bed's width, allowing for a compact design.

Benefits of technology

Enables rotation of the bed around both roll and pitch axes with a compact device configuration, reducing the overall size and weight of the tilting mechanism.

Abstract

To provide a bed device capable of rotating a bed part around a roll axis and a pitch axis with a compact device configuration.SOLUTION: The bed device 1 includes the bed portion 4 and the tilting portion 3 that tilts the bed portion 4, and the tilting portion 3 includes the fulcrum portion 10 that supports the bed portion 4 via the spherical bearing, the first driving device 20 that rotates the bed portion 4 around the roll axis r around the fulcrum portion 10, and the second driving device 30 that rotates the bed portion 4 around the pitch axis p around the fulcrum portion 10. The fulcrum portion 10, the first driver 20, and the second driver 30 are arranged on a central axis O1 passing through the center of the bed portion 4 in the widthwise direction (Y-axis direction).SELECTED DRAWING: Figure 2
