Patent ID: 7029176

Claim:
An X-ray apparatus for intraoral imaging applications, said apparatus comprising a linkage mounted on a support structure, to which is connected an X-ray source for generating X-radiation and directing the same to a receiver instrument placed in a patient's mouth, said linkage comprising: a first arm member articulated to the support structure and adapted to be pivotable around a substantially vertical axis; a second arm member connected to an end of the first arm member spaced from the support structure, said second arm member being adapted to be pivotable around a substantially vertical axis at a first end and around a horizontal axis at a second end; and a third arm member having an end connected to the second end of the second arm member and adapted to be pivotable around a substantially horizontal axis, an unconnected end of the third arm member having the X-ray source mounted thereon with an articulated joint which allows pivoting of the X-ray source to various positions, said first arm member designed to be adjustable in its length, wherein the first arm member comprises two telescopically fitted profiles of substantial rectangular cross section, an inner profile having its two opposite outside surfaces formed with recesses lengthwise of the inner profile and with a T-slot provided on a bottom side of each of the recesses, and an outer profile having its inside surface formed with inward protrusions complementary to said recesses and provided with fastening through-holes for the passage of fastening elements from the outer profile's outside surface to the T-slots for locking said profiles in a desired relative position in a longitudinal direction.
