Abstract

Abstract The invention relates to a device in connection with cameras for the support of flashlight units (14) on the socket (2) of the lens of the camera, so that the respective flashlight unit (14) will be supported in a laterally displaced manner relative to the central axis (7) of the lens. By means of the present invention a device is obtained, which among other things is suitable to use in connection with macrophotography, as the device can be handled in a rapid, simple and effective manner, and as the flashlight units (14) used will be located near to the front of the lens and follow the movements thereof. The device comprises a holder (3), which is arranged to be attached to the socket (2) of the lens of the camera at the front portion of the same. At least two pivoted flashlight supporting pivoting arms (8) are supported on this holder (3), the pivoting axes (6) of which arms (8) being located in diametrically opposed positions each one on its side of the socket (2) of the lens and extending at right angle relative to the central axis (7) of the lens. Each respective arm (8) at its end facing away from said pivot bearing (5, 9) exhibits a swivelling bearing (10, 11) where a swivelling arm (12) supporting the flashlight unit (14) is pivoted.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 118 words
A device for supporting a plurality of flashlight units at a camera having a lens with a lens socket defining a central axis, said device comprising: a holder, means for attaching said holder to said lens socket, at least two first arm means connected to said holder at diametrically opposite positions so as to be pivotable about first axes on opposite sides of said socket and at right angles to said central axis, said first arm means having ends remote from said socket, and at least two second arm means respectively pivotally connected to said remote ends so as to be pivotable about second axes, and at least two flashlight units respectively supported on said second arm means.
Claim 2
Independent Claim 118 words
A device for supporting a plurality of flashlight units at a camera having a lens with a lens socket defining a central axis, said device comprising: a holder, means for attaching said holder to said lens socket, at least two first arm means connected to said holder at diametrically opposite positions so as to be pivotable about first axes on opposite sides of said socket and at right angles to said central axis, said first arm means having ends remote from said socket, and at least two second arm means respectively pivotally connected to said remote ends so as to be pivotable about second axes, and at least two flashlight units respectively supported on said second arm means.
Claim 3
Dependent Claim 37 words
A device according to claim 1, wherein said first axis and said second axis, on one and the same side of said lens socket, extend at right angle relative to each other and in a common plane.
Claim 4
Dependent Claim 28 words
A device according to claim 1 or 2, wherein each of said first arm means comprises two arm sections extending at right angle with respect to each other.
Claim 5
Dependent Claim 15 words
A device according to claim 3, wherein said arm sections are of the same length.
Claim 6
Dependent Claim 43 words
A device according to claim 3, wherein each of said second arm means comprises a flat, straight bar, and means for pivotally mounting the respective flashlight unit on said bar so as to be pivotable about an axis parallel to said second axes.
Claim 7
Dependent Claim 69 words
A device according to claim 5, wherein each of said flashlight units comprises a window which is substantially in the same plane as the front of said lens socket when said first and second arm means, on one and the same side of said socket, are arranged at right angle relative to each other, and the common plane of said axes is parallel to the front of the lens.
Claim 8
Dependent Claim 23 words
A device according to claim 1 or 2, comprising bearings respectively defining said first and second axes, said bearings comprising friction locking bearings.
Claim 9
Dependent Claim 37 words
