Abstract
Abstract A level attachment for cameras is flanged to interengage with channel tracks of a camera hot shoe in either of two positions on orthogonal axes. The arrangement enables leveling the camera side-to-side and fore-and-aft. The level attachment is screw-threaded and can serve as a mounting for various camera accessories directly or through a threaded adapter.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
71 words
A leveling attachment for cameras which includes an accessory shoe for the mounting of a flash attachment on a camera comprising a camera leveling module including a bubble level element having one orthogonal axis, and the camera leveling module including a mounting base engageable with the accessory shoe on either of two orthogonal axes whereby the bubble level element may have its axis extending from side-to-side or fore-to-aft on the camera.
Claim 2
Dependent Claim
71 words
A leveling attachment for cameras which includes an accessory shoe for the mounting of a flash attachment on a camera comprising a camera leveling module including a bubble level element having one orthogonal axis, and the camera leveling module including a mounting base engageable with the accessory shoe on either of two orthogonal axes whereby the bubble level element may have its axis extending from side-to-side or fore-to-aft on the camera.
Claim 3
Dependent Claim
40 words
A leveling attachment for cameras as defined in claim 1, and the mounting base of the module comprising a rectangular plate adapted to enter between two channel tracks of a camera accessory shoe in either of two right angular positions.
Claim 4
Dependent Claim
48 words
A leveling attachment for cameras as defined in claim 2, and said plate being provided with two intersecting right angular grooves in its bottom face to enable passage of a projecting electrical contact element of the accessory shoe during engagement of the module therewith along either orthogonal axis.
Claim 5
Dependent Claim
34 words
A leveling attachment for cameras as defined in claim 1, and said module including a block-like body portion having an upper corner recess, and the bubble level element being fixedly held in said recess.
Claim 6
Dependent Claim
28 words
A leveling attachment for cameras as defined in claim 1, and a threaded bore in said module adapted to receive a threaded coupling element of a camera accessory.
Claim 7
Dependent Claim
29 words
A leveling attachment for cameras as defined in claim 5, and the threaded bore being across the axis of the bubble level element and perpendicular to said mounting base.
Claim 8
Dependent Claim
47 words
A leveling attachment for cameras as defined in claim 5, and a double-ended threaded coupling screw adapted for threaded engagement at one end with the threaded bore of said module and adapted for threaded engagement at its other end with a threaded opening of a camera accessory.
