Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
168 words
Lens mount for connection to a camera (1), with a first mount component (6) which can be connected to the camera and a second mount component (9) supported in the first component, with component (9) serving as a holding device for optical elements (13) and being axially displaceable in component (6), with one of the mount components having an annular groove (15) in which an element is inserted which rests radially and elastically against the entire circumference of the cylindrical surface (17) of the other mount component; characterized by the fact that the groove (15) has a rectangular cross-section, that a radially elastic element (18, 19) is inserted in this groove and that a slotted plastic strip with a rectangular cross-section is placed on top of it, that the plastic strip (16[ is made of material with good dry sliding properties and seals the air slit between the two mount components (6) and (9) along their entire circumferences to prevent the propagation of noise through this air slit.
