Abstract
Abstract A connection arrangement for coupling a holder for at least one flash bulb to a camera includes a magnetic system in the camera adapted to cooperate to a ferromagnetic portion of the holder. Symmetrical positioning elements which preferably have a searching construction form part of the holder and enable the holder to be used in two separate orientations which are 180* relative to each other.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
128 words
In a camera, an improved connection arrangement for connecting at least two electric contact members in the camera to corresponding contact members in a holder for at least one flash bulb and for mechanically coupling said camera to said holder, said arrangement comprising: at least two magnetic members positioned on the outside of said camera and adapted to cooperate with a ferromagnetic portion of said holder, said magnetic members also constituting a single electric contact member; at least two apertures arranged symmetrically about said magnetic members on the outside of said camera adapted to cooperate with positioning members on said holder and for positioning said holder; and a second electric contact member on the outside of said camera adapted to cooperate with a contact member on said holder.
Claim 2
Dependent Claim
128 words
In a camera, an improved connection arrangement for connecting at least two electric contact members in the camera to corresponding contact members in a holder for at least one flash bulb and for mechanically coupling said camera to said holder, said arrangement comprising: at least two magnetic members positioned on the outside of said camera and adapted to cooperate with a ferromagnetic portion of said holder, said magnetic members also constituting a single electric contact member; at least two apertures arranged symmetrically about said magnetic members on the outside of said camera adapted to cooperate with positioning members on said holder and for positioning said holder; and a second electric contact member on the outside of said camera adapted to cooperate with a contact member on said holder.
Claim 3
Dependent Claim
128 words
In a camera, an improved connection arrangement for connecting at least two electric contact members in the camera to corresponding contact members in a holder for at least one flash bulb and for mechanically coupling said camera to said holder, said arrangement comprising: at least two magnetic members positioned on the outside of said camera and adapted to cooperate with a ferromagnetic portion of said holder, said magnetic members also constituting a single electric contact member; at least two apertures arranged symmetrically about said magnetic members on the outside of said camera adapted to cooperate with positioning members on said holder and for positioning said holder; and a second electric contact member on the outside of said camera adapted to cooperate with a contact member on said holder.
Claim 4
Dependent Claim
128 words
In a camera, an improved connection arrangement for connecting at least two electric contact members in the camera to corresponding contact members in a holder for at least one flash bulb and for mechanically coupling said camera to said holder, said arrangement comprising: at least two magnetic members positioned on the outside of said camera and adapted to cooperate with a ferromagnetic portion of said holder, said magnetic members also constituting a single electric contact member; at least two apertures arranged symmetrically about said magnetic members on the outside of said camera adapted to cooperate with positioning members on said holder and for positioning said holder; and a second electric contact member on the outside of said camera adapted to cooperate with a contact member on said holder.
Claim 5
Dependent Claim
133 words
In combination with said camera of claim 1, a holder for at least one flash bulb comprising: a base plate including a symmetric ferromagnetic plate, said magnetic plate also being constructed as a contact member for said flash bulb and adapted to couple to said magnetic members in said camera; orienting cams symmetrically arranged on either side of said plate for searchingly interfilling with the apertures provided in said camera; and contact members symmetrically arranged on either side of said plate, each of which capable of cooperating with and coupling to said second contact member on said camera, whereby the symmetrical arrangement of said magnetic plate, cams and contact members enables the holder to be coupled to said camera in either of two positions which are rotatably relative to each other by 180*.
Claim 6
Dependent Claim
14 words
The combination of claim 2 wherein said orienting cams are of a conical shape.
