Mounting apparatus for optical examination devices connected to a projector through a light-conducting cable

Claim 2

A mounting apparatus for an optical examination instrument, said instrument being connected at the distal end of a light-conducting cable coupled to a source of light at its near end, said apparatus comprising: a lower mount adapted to support said instrument at the lower end thereof, said lower mount having a slit therein for the passage of said light-conducting cable; and an upper mount serving as a holding device for said instrument, the end of said instrument connected to said light-conducting cable being supported on said lower mount, and an upper portion of said instrument being held in said upper mount.

Claim 3

A mounting apparatus according to claim 1 wherein said upper mount includes a holding surface displaced from the vertical with respect to said lower mount, so that said hand grip rests in a diagonal position.

Claim 4

A mounting apparatus according to claim 1 wherein said upper mount includes a holding surface having a magnet therein, said instrument being provided at the level of said upper mount with a part including magnetizable material.

Claim 5

A mounting apparatus according to claim 1 further comprising: switching means connected to turn said light source on and off; and sensing means in said mounting apparatus, responsive to the mounting of said instrument therein, for operating said switching means, so that said light source is turned off when said instrument is mounted and is turned on when said instrument is removed from said mounting apparatus.

Claim 6

In combination with a cold-light projector including a plurality of light-conducting cables each connected at its near end to a source of light in said projector and having a hand grip at its distal end adapted to receive an optical examination device, a plurality of mounting apparatuses according to claim 1, each dedicated to mounting the hand grip connected to a different one of said light-conducting cables and an optical examination device receivable thereon, the lower mount and upper mount of each mounting apparatus being secured to said projector.

Claim 7

The combination of claim 5 further including: switching means connected with the light source corresponding to each light-conducting cable for turning said light source on and off; and sensing means in each mounting apparatus, responsive to the placement of a hard grip therein, for operating the corresponding switching means, so that a light source is turned off when a hand grip is mounted in the corresponding mounting apparatus and is turned on when the hand grip is removed therefrom.

Claim 8

The combination of claim 6 wherein said switching means are connected so that only one of said light sources can be illuminated at a time.

Claim 9

In combination with a cold-light projector including two light-conducting cables each connected at its near end to a source of light in said projector and having an optical examination instrument at its distal end: a pair of mounting apparatuses according to claim 1, each dedicated to mounting said instrument thereon, the lower mount and upper mount of each of said mounting apparatuses being secured to said projector; a line wired to receive power; a pair of two position microswitches each having a switching contact operable between an OFF fixed contact and an ON fixed contact, each of said OFF fixed contacts being connected to said line, each of said light sources being connected between the ON fixed contact of a corresponding microswitch and a common connection; a pair of lamp switches each having a switching contact operable between an OFF fixed contact connected to said line and an ON fixed contact connected to the switching contact of a corresponding one of said microswitches, the switching contacts of said lamp switches being connected together; and sensing means in each mounting apparatus, responsive to the placement of said instrument therein, for moving the switching contact of the corresponding microswitch to its OFF fixed contact, said switching contact being moved to the ON fixed contact when said instrument is removed.
