Handgrip for an electro-optical diagnostic apparatus set

Claim 1

A handgrip adaption set for an electro-optical apparatus set comprising: a tubularly-shaped battery housing for receiving any, energy source selected from a predetermined plurality of energy sources with different configurations for energizing a light source, said housing having a first housing attachment element at a first end thereof and a second housing attachment element at an opposite, second, end thereof; a set of interchangeable, releasably-attachable, end covers, each for being mounted to the first housing attachment element at the first end of the battery housing, said set of interchangeable releasably-attachable end covers including: at least a first end cover comprising a solid first end cap and a first contact spring attached at an inner side of the first end cap for making contact with a first energy source when it is in said battery housing and said first end cover is mounted at said first end of said battery housing; at least a second end cover comprising a second end cap with an opening therein and a second contact spring attached at an inner side of the second cap for making contact with a second energy source when it is in said battery housing and said second end cover is mounted at said first end of said battery housing; at least a third end cover comprising a third end cap and a third contact spring for making contact with a third energy source when it is in said battery housing and said third end cover is mounted at said first end of said battery housing, said third energy source being substantially smaller than at least one of said other energy sources, wherein, said third end cover includes a third-cover adapting piece, including a charging electronic circuit for charging said third energy source, mounted between the third end cap and the third contact spring; at least a fourth end cover comprising a fourth end cap, a fourth-cover adapting piece including a charging electronic circuit mounted on said fourth end cap, and a fourth contact spring supported by said fourth-cover adapting piece for making contact with a fourth energy source when it is mounted in said battery housing and said fourth end cover is mounted at said first end of said battery housing, said fourth energy source being substantially shorter than said third energy source, wherein said fourth end cover further includes an auxiliary fourth-cover adapting piece, with a smaller diameter than the diameter of the fourth-cover adapting piece, disposed between the fourth-cover adapting piece and the fourth contact spring to bridge an empty space between the fourth-cover adapting piece and the fourth energy source; at least a fifth end cover comprising a fifth end cap with a two-pole plug thereon serving to provide a coupling for connection to a normal main electrical supply, a fifth contact spring and a fifth-cover adapting piece, including a charging electronic circuit, disposed between the fifth contact spring and the fifth end cap; and at least a sixth end cover comprising a sixth end cap with a two-pole plug serving to provide a coupling for connection to a normal main electrical supply, a sixth-cover adapting piece including a charging electronic circuit, a sixth contact spring, and an auxiliary sixth-cover adapting piece having a smaller diameter than the diameter of the sixth-cover adapting piece serving to bridge an empty space between the sixth-cover adapting piece and a sixth energy source when it is mounted in the battery housing and being disposed between the sixth contact spring and the sixth-cover adapting piece; at least one releasably-attachable coupling piece for being mounted to the second housing attachment element at said opposite, second end of said battery housing for mounting a scope instrument head to said opposite, second, end of the battery housing; wherein each end cover of said set of releasably-attachable end covers has a cover attachment element, adapted to mate with the said first housing attachment element.
