Abstract
Abstract An instructional display device for use in teaching and in operating teleorentgenography equipment, including a hollow rubber facsimile of a part of the human body attached to a support and a thin rod extending through the facsimile in a predetermined path. The hollow facsimile is arranged to assume an expanded position at which the rod simulates the path of an X-ray beam, and a compressed position at which the facsimile is conveniently stored in a box-like container or against the back surface of an adjacent support member. The support member may also include a representation of an actual X-ray photograph taken of such part of the human body along a line corresponding to the path of the rod through the expanded facsimile. Also, written materials may be provided for indicating the purpose and procedure for taking the particular X-ray indicated by the display device.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
128 words
An instructional display device including a support member, a three-dimensional facsimile of a part of the human anatomy secured to a surface of said support member, said facsimile being formed of a flexiblE material and being hollow to permit said facsimile to assume an expanded disposition projecting substantially outwardly from said support member surface and a compressed disposition substantially flat against said support member surface, linear means extending through a predetermined portion of said hollow facsimile in said expanded disposition thereof for simulating the path of a radiation beam passing through said facsimile, said linear means being arranged to be parallel to and adjacent said support member surface in said compressed disposition of said facsimile, and pressing means for selectively compressing said facsimile against said support member surface.
Claim 2
Dependent Claim
128 words
An instructional display device including a support member, a three-dimensional facsimile of a part of the human anatomy secured to a surface of said support member, said facsimile being formed of a flexiblE material and being hollow to permit said facsimile to assume an expanded disposition projecting substantially outwardly from said support member surface and a compressed disposition substantially flat against said support member surface, linear means extending through a predetermined portion of said hollow facsimile in said expanded disposition thereof for simulating the path of a radiation beam passing through said facsimile, said linear means being arranged to be parallel to and adjacent said support member surface in said compressed disposition of said facsimile, and pressing means for selectively compressing said facsimile against said support member surface.
Claim 3
Dependent Claim
50 words
An instructional display device as defined in claim 1 and further characterized in that said support member has attached thereto a representation of an actual X-ray photograph taken of said part of the human anatomy along the line corresponding to the path defined by said linear means through said facsimile.
Claim 4
Dependent Claim
49 words
An instructional display device as defined in claim 1 and further characterized in that said linear means comprises a small rod supported solely by said facsimile whereby said rod is free to be parallel and adjacent said support member surface when said facsimile is at said compressed disposition thereof.
Claim 5
Dependent Claim
65 words
An instructional display device as defined in claim 3 and further characterized in that both ends of said rod extend slightly beyond said facsimile, and in that said support member is formed of a clear material whereby the end of said rod nearest said support member will be visible from the surface of said support opposite to said surface to which said facsimile is secured.
Claim 6
Dependent Claim
109 words
An instructional display device as defined in claim 1 and further characterized in that said means for selectively pressing said facsimile to the compressed disposition thereof includes a box-like container having an open top and a depth corresponding substantially to the thickness of said facsimile in the compressed disposition thereof, and in that said support member is mounted with a hinged connector to said box-like container for selective movement between a first open position at which said facsimile assumes said expanded disposition thereof and a second position closing the open top of said box-like container and pressing the said facsimile to said compressed disposition thereof within said box-like container.
Claim 7
Dependent Claim
78 words
An instructional display device as defined in claim 1 and further characterized in that said support member and said pressing means are slidably mounted on guide means permitting said support member to be selectively located at a first position at which said facsimile is compressed between said support member and said pressing means and a second position at which said pressing means is spaced from said support means to permit said facsimile to assume said expanded disposition thereof.
