Abstract
The present technology relates to a circular-arc-shaped hybrid C-profile for a C-arm X-ray apparatus, said profile having a lightweight profile as the main body and a steel profile as a support profile for a bearing unit, the lightweight profile and the steel profile being connected to one another by connecting means.
Core Innovation
The invention relates to a hybrid C-profile for a C-arm of a C-arm X-ray apparatus, where the C-arm is movably guided along its periphery on a support profile in a bearing unit. The hybrid C-profile comprises a main body with a circular-arc-shaped lightweight profile and a support profile with a circular-arc-shaped steel profile connected to one another by connecting means. The support profile provides running surfaces and guide rails for guidance elements with rollers.
The steel profile includes a cylindrical casing-shaped portion with a convex side and a concave side, wherein first running surfaces are formed on the convex side and second running surfaces for support rollers are formed on the concave side. A first lateral edge and a second lateral edge of the cylindrical casing-shaped portion comprise guide rails for guide rollers of the bearing unit. The described structure aims at improved load resistance and torsional stiffness compared with prior C-profiles, while using a lightweight hollow profile with an attached steel profile that provides bearing running surfaces.
The hybrid C-profile includes internal channels or ducts for energy supply lines, data supply lines, and coolant lines, and optionally heat-exchanger sidewalls. The structure is described with specific mechanical and connection geometries, including tongue-and-groove joints with fixing by bonded, riveted, soldered, or welded connections, including undercuts for adhesive bonding.
Claims Coverage
The independent claim defines one hybrid C-profile for a C-arm X-ray apparatus with a circular-arc-shaped lightweight profile and a circular-arc-shaped steel support profile connected by connecting means, where the C-arm is movably guided in a bearing unit along the profile periphery. One independent claim is identified, with two main inventive features summarized as follows.
Hybrid C-profile for movably guided C-arm X-ray apparatus
A hybrid C-profile for a C-arm of a C-arm X-ray apparatus in which the C-arm is movably guided along the periphery thereof on a support profile in a bearing unit, the hybrid C-profile comprising a main body having a circular-arc-shaped lightweight profile; and a support profile having a circular-arc-shaped steel profile, wherein the circular-arc-shaped lightweight profile and the circular-arc-shaped steel profile are connected to one another by connecting means.
Cylindrical casing-shaped steel profile with running surfaces and guide rails
The support profile comprises a cylindrical casing-shaped portion having a convex side and a concave side, wherein first running surfaces are formed on the convex side, wherein second running surfaces for support rollers are formed on the concave side, and wherein a first lateral edge and a second lateral edge of the cylindrical casing-shaped portion comprise guide rails for guide rollers of the bearing unit.
Across the independent claim, the core inventive coverage is the combination of a circular-arc-shaped lightweight profile with a circular-arc-shaped steel cylindrical casing-shaped portion providing running surfaces and guide rails, connected by connecting means, for a movably guided C-arm in a bearing unit.
Stated Advantages
Improved load resistance.
Improved torsional stiffness compared with prior C-profiles.
Documented Applications
C-arm of a C-arm X-ray apparatus, including a mobile C-arm X-ray apparatus embodiment with reproducible positioning.
