Claims
- 1. In a dental x-ray assembly having articulating positioning arm members for an x-ray tube assembly and connected within said dental x-ray assembly by adjustable linkage mounting members for shaft members associated with said positioning arm members, each of said adjustable linkage mounting members comprised of a housing member mounted within a chamber of said adjustable linkage mounting members for receiving a shaft member of a positioning arm member, means for adjustable frictional engagement with said shaft member in response to means rotatably disposed within said chamber.
- 2. The dental x-ray assembly as defined in claim 1 wherein said chamber is cylindrically-shaped and said housing member is cylindrically-shaped with a U-shaped end portion for receiving in rotational relationship said shaft of said positioning arm member.
- 3. The dental x-ray assembly as defined in claim 1 wherein said means for frictionally engaging said shaft member is a cylindrically-shaped brake shoe member having a semi-circular surface for cooperating with said U-shaped end portion of said housing member.
- 4. The dental x-ray assembly as defined in claim 1 wherein said housing member includes an end cap portion extending outwardly from said linkage mounting member formed with an internal threaded surface for receiving a threaded member included in said adjusting means.
- 5. The dental x-ray assembly as defined in claim 4 and further including a cylindrically-shaped compression member disposed in said chamber for movement in response to rotational movement of said threaded member within said housing member.
- 6. The dental x-ray assembly as defined in claim 5 wherein a spring washer set is positioned within said chamber between said brake shoe member and said compression member to facilitate adjustment of frictional contact of said brake shoe with said shaft.
- 7. The dental x-ray assembly as defined in claim 1 wherein said adjustable linkage mounting member includes an outwardly extending arm portion wherein said chamber is disposed in said arm portion downwardly at an angle with respect to a major axis of said adjustable linkage mounting member.
- 8. The dental x-ray assembly as defined in claim 7 wherein said angle is 45 degrees with respect to said major axis of said adjustable linkage mounting member.
