Abstract
Abstract This disclosure relates to a simple mounting structure for a dental X-ray apparatus. The structure is used in combination with a substantially horizontal treatment bed in such manner that irradiation tube of an X-ray head is designed to take a correct position with respect to the mouth region of a patient lying on the treatment bed with his head resting on the headrest of the bed. The structure includes the treatment bed, an X-ray head support connected to one side of the bed and made up of an assembly of a plurality of hollow tubes adjustable in length in the three-dimensional directions of length, width and height of the bed and an X-ray head mounted at the end of the support and swingable in a back-and-forth direction with respect to an axis of the irradiation tube. The irradiation tube is mounted on the X-ray head and movable toward and away from the mouth region. The structure permits simple and correct positioning of the X-ray apparatus with respect to a patient lying on the bed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
145 words
A simple mounting structure in a dental X-ray apparatus for use in combination with a substantially horizontal treatment bed to position an irradiation tube of an X-ray head in a specified and repeatable position with respect to the mouth region of a patient with his head placed on a headrest of the bed, said structure being characterized in that the structure comprises said treatment bed, an X-ray head support connected to one side of said bed and comprising an assembly of a plurality of hollow tubes adjustable in length in the three-dimensional directions of length, width and height of said head, and an X-ray head mounted at the end of said support and swingable in a back-and-forth direction with respect to an axis of said irradiation tube, said irradiation tube being mounted on said X-ray head and movable toward and away from said mouth region.
Claim 2
Dependent Claim
145 words
A simple mounting structure in a dental X-ray apparatus for use in combination with a substantially horizontal treatment bed to position an irradiation tube of an X-ray head in a specified and repeatable position with respect to the mouth region of a patient with his head placed on a headrest of the bed, said structure being characterized in that the structure comprises said treatment bed, an X-ray head support connected to one side of said bed and comprising an assembly of a plurality of hollow tubes adjustable in length in the three-dimensional directions of length, width and height of said head, and an X-ray head mounted at the end of said support and swingable in a back-and-forth direction with respect to an axis of said irradiation tube, said irradiation tube being mounted on said X-ray head and movable toward and away from said mouth region.
Claim 3
Dependent Claim
160 words
A structure according to claim 1, wherein said support comprises a storing track mounted on one side of said treatment bed along the longitudinal direction of the bed, a slider slidably inserted into said track with respect to the longitudinal direction of the track, a stand pole telescopable tube connected in a vertical direction to the end of said slider, a stand pole slidably inserted into said telescopable tube in the vertical direction and movable around the axis of the tube and having a horizontally curved portion on the top thereof, and an operating tube slidably fitted into said curved portion with respect to the direction of width, whereby when the X-ray head is attached to said operating tube and when said tube and said stand pole are telescoped into said stand pole telescopable tube and when said slider is telescoped into said storing track, said X-ray head and said support are telescoped into one side of said treatment bed.
Claim 4
Dependent Claim
29 words
A structure according to claim 2, wherein said stand pole telescopable tube and said stand pole are provided with stoppers for locking said tube and stand pole in position.
Claim 5
Dependent Claim
84 words
A structure according to claim 3, wherein said stand pole comprises a vertical pole and a curved pole, said curved pole being slidable in the direction of height with respect to said vertical pole and being rotatably inserted into said vertical pole around the axis thereof and having an about 90° curved portion, said vertical pole and said curved pole including a screw stopper for locking the vertical and curved poles in position at the point at which one is fitted into the other.
Claim 6
Dependent Claim
22 words
A structure according to claim 2, wherein said stand pole telescopable tube is equipped with a control box for operating X-ray photographing.
Claim 7
Dependent Claim
25 words
A structure according to claim 2, wherein said slider and said stand pole telescopable tube are connected to each other through a horizontal connecting block.
Claim 8
Dependent Claim
