专利汇可以提供Adjustable shield device for shielding x-rays专利检索，专利查询，专利分析的服务。并且A generally triangular lead shield has a handle bar extended from its base slideably and rotatably through an adjustable head on the free end of a telescopic element, which latter is slideable and rotatable in a tube on a rotatable mounting bracket adapted to be secured to the housing of an X-ray tube, whereby the position of the shield can be adjusted vertically or horizontally or into an out of the way position, and the shadow area can be varied by turning the handle bar and the shield about a horizontal axis relatively to said X-rays.，下面是Adjustable shield device for shielding x-rays专利的具体信息内容。

权利要求

1. In an adjustable shield device for forming a shadow area in the path of X-rays from an X-ray tube in a housing including, a shield capable of obstructing X-rays, and means to adjustably support the said shield, the improvement comprising mounting means for said shield, a telescopic element on said mounting means, a member slideable and rotatable relatively to said telescoping element, said shield being on said slideable and rotatable member and said member being manipulable to adjust the position of said shield below said X-ray tube and to vary the extent of the shadow area by turning said shield to vary its angular position relatively to said tube.

2. The adjustable shield device specified in claim 1, and said shield having a geometrical outline for a maximum shaded area when substantially at right angles to said X-ray, and said area being reducible by said turning of said shield so as to incline said shield relatively to the direction of said X-ray.

3. The adjustable shield device specified in claim 2, and said shield being substantially flat.

4. The adjustable shield device specified in claim 2, and said shield being substantially flat with converging longitudinal edges.

5. The adjustable shield device specified in claim 1, and said mounting means including a mounting housing adapted to be attached to the X-ray tube housing, and a rotatable bracket on said mounting housing supporting said telescopic element for permitting the turning of said telescoping element for changing the position of said shield.

6. The adjustable shield device specified in claim 5, and a tubular base for said telescopic element being mounted on said bracket, said telescopic element being slideable in said tubular base, and means to secure said telescopic element in said tubular base in adjusted positions.

7. The adjustable shield device specified in claim 5, and a tubular base for said telescopic element being mounted on said bracket, said telescopic element being slideable and rotatable in said tubular base for adjustment of said shield vertically and horizontally in the field of said X-ray, and means to secure said telescopic element in said tubular base in adjusted position.

8. The adjustable shield device specified in claim 7, and said slideable and rotatable member being a handle bar extended from said shield, and means to rotatably support said handle bar on said telescopic element for angular adjustment of said shield, and slideably for horizontally positioning said shield in the field of said X-ray.

9. The adjustable shield device specified in claim 1, and said mounting means including a mounting band capable of surrounding said X-ray tube housing, a bracket, means on said bracket to anchor one end of said band, and tightening means adjustable on said bracket connected to the other end of said band whereby said band is tightened on the outer periphery of said X-ray tube housing, a mounting base supported on said bracket concentrically with said band for substantial registry with the axis of said X-ray tube housing, and means to mount said vertically adjustable element on said mounting base.

10. The adjustable shield device specified in claim 9, and said mounting base being adapted to rest upon adjacent face of said X-ray tube housing, and said mounting means Including a rotatable bracket for supporting said vertically adjustable element.
