Abstract

The invention relates to a connecting bridge to connect two optical units. This connecting bridge is fitted in each case with at least one coupling for each optical unit making possible, besides mechanical coupling, also transmitting electronic signals and/or setting up an electrical connection.

Claims

1. A connecting bridge (10) to connect two optical units (110), each comprising a battery, comprising:

at least one coupling (20) for coupling each optical unit (110) to the connecting bridge (10), said connecting bridge being fitted with both mechanical coupling elements (22) and electronic coupling elements (24) that are configured in a manner that the electronic coupling elements (24) set up electronic contact between the connecting bridge (10) and the optical units (110) coupled thereto when the mechanical coupling elements (22) set up mechanical contact between the coupled optical units (110) and the connecting bridge (10),

a connector (30) extending at least in segments between each of the couplings (20) and mechanically linking the couplings to each other, and

an analyzer (40) which is part of the connecting bridge (10) and can be electronically connected to the electronic coupling elements (24) of the optical units (110) and can exchange electronic signals with the electronic coupling elements (24) and/or can set up an electric connection between the electronic coupling elements (24) of the couplings (20),

the analyzer (40) analyzes signals received from the electronic coupling elements (24) regarding a battery status of the optical units (110) and generates an electric connection to the batteries of both optical units 110 via the electronic coupling elements (24) to support the battery having a lower charge by the battery having a larger charge.

2. The connecting bridge (10) as claimed in claim 1, characterized in that the connector (30) is connected by at least one rotary joint to at least one of the couplings (20) in a manner that the coupling so connected can rotate at least partly about the axis of rotation of the at least one rotary joint relative to the connector (30).

3. The connecting bridge (10) as claimed in claim 1, characterized in that the connecting bridge (30) is connected using one translational element to at least one of the couplings (20) in a manner that the spacing of the coupling (20) so connected to the connector (30) is variable.

4. The connecting bridge (10) as claimed in claim 1, characterized in that the electric coupling element (24) and the mechanical coupling element (22) of at least one of the couplings (20) are at least partly integral with one another.

5. The connecting bridge (10) as claimed in claim 1, characterized in that the mechanical coupling element (22) of at least one of the couplings (20) is designed to be at least partly a dovetail guide.

6. The connecting bridge (10) as claimed by claim 1, characterized by fasteners (32) affixing the mechanical coupling element (22) of at least one of the couplings (20) when the at least one coupling is linked to one of the optical units (110).

7. The connecting bridge (10) as claimed in claim 1, characterized in that the electronic coupling element (24) of at least one of the couplings (20) are constituted in part by contact surfaces (25) able to make contact a matching contact surface (125) of the coupled optical unit (110).

operability status of the optical units,

ambient parameters of the optical operational situation, and

low light-level intensity.

10. The connecting bridge (10) as claimed in claim 1, further comprising a regulator (50) connected to the analyzer (40) for the purpose of exchanging signals with the analyzer and regulating at least one of the optical units (110) as a function of the electronic signals from the analyzer (40).

11. The connecting bridge (10) as claimed in claim 1, characterized in that the mechanical coupling elements (22) of at least one of the couplings (20) allow adjusting a position of the coupled optical unit (110) relative to the connecting bridge (10) in the axial direction along the optic axis of the coupled optical unit (110).

12.
