Abstract

The stand base is for a surgical microscope. The stand base is for setting up on a floor configured as a planar surface and includes at least a first weight module; a base body defining an underside and accommodating the first weight module; a support arrangement connected to the base body and supporting the stand base with at least three support points in contact engagement with the floor to permit setting up the stand base; the support points conjointly defining a support plane whereat the support points are in contact engagement with the floor; the underside of the base body facing toward the support plane; an ancillary body; the base body having a receiving arrangement in the underside for releasably accommodating the ancillary body; and, the underside of the base body and the support plane conjointly defining a smallest spacing therebetween which is greater than 10 cm.

First claim

What is claimed is:

1. A weight module for a stand base for a surgical microscope, the stand base being for setting up on a floor configured as a planar surface and the stand base including: a base body defining an underside and being configured to accommodate the weight module; a support arrangement connected to the base body and being configured to support the stand base with at least three support points in contact engagement with the floor to permit setting up the stand base; the support points conjointly defining a support plane whereat the support points are in contact engagement with the floor; the underside of the base body facing toward the support plane; an ancillary body; the base body having a receiving arrangement configured in the underside for releasably accommodating the ancillary body; and, the underside of the base body and the support plane conjointly defining a smallest spacing therebetween which is greater than 10 cm; the weight module comprising:
a weight module body having an upper side and an underside;
said weight module body defining a first through-hole between said upper side and said underside;
said weight module body further having a first threaded bore in said underside;
said first threaded bore extending parallel to said first through-hole;
said first through-hole defining a first through-hole central axis and a first through-hole diameter;
said first threaded bore defining a first threaded bore central axis;
said first threaded bore central axis and said first through-hole central axis defining an imaginary connecting line therebetween;
said weight module body further having a middle axis disposed on said imaginary connecting line such that a first distance between said first through-hole central axis and said middle axis has the same value as a second distance between said middle axis and said first threaded bore central axis; and,
said first threaded bore is configured such that said first threaded bore has an outer diameter which is smaller than said first through-hole diameter.

2. The weight module of claim 1 , wherein:
said weight module body further defines a second through-hole between said upper side and said underside;
said second through-hole has a second through-hole diameter and extends parallel to said first through-hole;
said weight module body further having a second threaded bore has a second threaded bore outer diameter and extends parallel to said second through-hole;
said second threaded bore outer diameter is smaller than said second through-hole diameter;
said second through-hole defines a second through-hole central axis;
said second threaded bore defines a second threaded bore central axis;
said second through-hole central axis having a third distance to said middle axis;
said second threaded bore central axis having a fourth distance to said middle axis;
said third distance being equal to said fourth distance;
said first through-hole central axis and said first threaded bore central axis defining a first plane;
said second through-hole central axis and said second threaded bore central axis defining a second plane;
said first plane and said second plane being identical or orthogonal to each other; and,
said middle axis lies in both said first and said second plane.

3. The weight module of claim 1 , wherein said upper side and said underside of said weight module body are configured complementary in form to each other.

4. A system comprising:
a first weight module and a second weight module;
a stand base for a surgical microscope, the stand base being for setting up on a floor configured as a planar surface and the stand base including: a base body defining an underside and being configured to accommodate said first and second weight modules; a support arrangement connected to the base body and being configured to support the stand base with at least three support points in contact engagement with the floor to permit setting up the stand base; the support points conjointly defining a support plane whereat the support points are in contact engagement with the floor; the underside of the base body facing toward the support plane; an ancillary body; the base body having a receiving arrangement configured in the underside for releasably accommodating the ancillary body; and, the underside of the base body and the support plane conjointly defining a smallest spacing therebetween which is greater than 10 cm;
said first weight module and said second weight module each including a respective weight module body having a module upper side and a module underside;
each of said weight module bodies defining a first through-hole between the corresponding ones of said module upper side and said module underside;
each of said weight module bodies further having a first threaded bore in the corresponding one of said module undersides;
each of said first threaded bores extending parallel to the corresponding one of said first through-holes;
each of said first through-holes defining a respective first through-hole central axis and a respective first through-hole diameter;
each of said first threaded bores defining a respective first threaded bore central axis;
respective ones of said first threaded bore central axes and said first through-hole central axes each defining a respective imaginary connecting line therebetween;
said weight module bodies of said first and said second weight modules conjointly defining a middle axis disposed on each of said imaginary connecting lines such that a respective first distance between each of said first through-hole central axes and said middle axis has the same value as a second distance between said middle axis and the corresponding one of said first threaded bore central axes; and,
each of said first threaded bores being configured such that each of said first threaded bores has a respective outer diameter which is smaller than the corresponding one of said first through-hole diameters;
each of said weight module bodies further defining a second through-hole between the corresponding ones of said upper side and said module underside;
each of said second through-holes having a respective second through-hole diameter and extending parallel to the corresponding one of said first through-holes;
each of said weight module bodies further having a respective second threaded bore having a respective second threaded bore outer diameter and extending parallel to the corresponding one of said second through-holes;
each of said second threaded bore outer diameters being smaller than the corresponding one of said second through-hole diameters;
each of said second through-holes defining a respective second through-hole central axis;
each of said second threaded bores defining a respective second threaded bore central axis;
each of said second through-hole central axes having a respective third distance to said middle axis;
each of said second threaded bore central axes having a respective fourth distance to said middle axis;
each of said third distances being equal to the corresponding one of said fourth distances; and,
said second weight module being arranged rotated 180° about said middle axis relative to said first weight module such that said first through-hole central axis of said second weight module and said first threaded bore central axis of said first weight module lie on a first imaginary straight line and said second through-hole central axis of said second weight module and said second threaded bore central axis of said first weight module lie on a second imaginary straight line.
