Abstract

A longitudinally displaceable bar interconnects the two locking members and movement of the bar toward either of the locking members will tilt the locking member to permit insertion of the cassette.

Total Claims: 6
Claim 1
Independent Claim
349 words
A holder for an x-ray film cassette comprising a frame formed by upper and lower guide rails arranged in spaced parallel relationship to each other for receiving and holding therebetween said cassette, said guide rails lying in a plane forming the plane of insertion of said cassette, a single sliding bar slidably mounted on said frame between a center position, a first operative position and a second operative position, first and second locking members comprising substantially angle-section members mounted on opposite ends of said sliding bar for pivotal movement between a closed and opened position for securing and positioning said cassette within the holder, a first roller rotatably attached to each of said locking members, said first rollers of said locking members cooperating with a supporting surface of said frame for guiding said members into a locking position, a second roller associated with each of said locking members rotatably mounted on said frame, said first roller of one of said locking members engaging said second roller associated therewith when said bar is displaced toward said locking member so as to cause said locking member to pivot in a plane parallel to the plane of insertion of the cassette between the closed and opened position, handle means attached to said bar for causing sliding movement thereof from said center positioN in one direction to said first operative position for causing said first and second rollers of said first locking members only to engage each other thereby causing said locking member to pivot in the same direction as said bar is moved to the opened position and thereby allow insertion and withdrawal of said cassette from the side of said first locking member, and for causing displacement of said bar in the other direction to said second operative position to cause pivoting in that direction of said second locking member only to the opened position to allow insertion and withdrawal of said cassette from the other side of said frame, and biasing means connected with said handle for locking said bar so that said cassette is secured between said locking members.
Claim 2
Dependent Claim

A holder for an x-ray film cassette comprising a frame formed by upper and lower guide rails arranged in spaced parallel relationship to each other for receiving and holding therebetween said cassette, said guide rails lying in a plane forming the plane of insertion of said cassette, a single sliding bar slidably mounted on said frame between a center position, a first operative position and a second operative position, first and second locking members comprising substantially angle-section members mounted on opposite ends of said sliding bar for pivotal movement between a closed and opened position for securing and positioning said cassette within the holder, a first roller rotatably attached to each of said locking members, said first rollers of said locking members cooperating with a supporting surface of said frame for guiding said members into a locking position, a second roller associated with each of said locking members rotatably mounted on said frame, said first roller of one of said locking members engaging said second roller associated therewith when said bar is displaced toward said locking member so as to cause said locking member to pivot in a plane parallel to the plane of insertion of the cassette between the closed and opened position, handle means attached to said bar for causing sliding movement thereof from said center positioN in one direction to said first operative position for causing said first and second rollers of said first locking members only to engage each other thereby causing said locking member to pivot in the same direction as said bar is moved to the opened position and thereby allow insertion and withdrawal of said cassette from the side of said first locking member, and for causing displacement of said bar in the other direction to said second operative position to cause pivoting in that direction of said second locking member only to the opened position to allow insertion and withdrawal of said cassette from the other side of said frame, and biasing means connected with said handle for locking said bar so that said cassette is secured between said locking members.
Claim 3
Dependent Claim
152 words
A holder for an x-ray film cassette comprising a frame formed by at least one guide rail for receiving said cassette, a pair of substantially angle-section members mounted on said frame for pivotal movement between an opened and closed position for holding the cassette therebetween when in the closed position, connecting means movably mounted between said angle-section members for movement between a center and two opposing operative positions, means for causing pivotal movement of each angle-section member when said connecting means is displaced toward said angle-section member to thereby pivot only the angle-section member toward which the connecting means is displaced to an open position so as to unlock the frame and allow insertion of said cassette, said angle section members being mounted for pivotal movement in a plane parallel to the plane of insertion of said cassette, and means attached to said connecting means for causing displacement of said connecting means.
Claim 4
Dependent Claim
152 words
A holder for an x-ray film cassette comprising a frame formed by at least one guide rail for receiving said cassette, a pair of substantially angle-section members mounted on said frame for pivotal movement between an opened and closed position for holding the cassette therebetween when in the closed position, connecting means movably mounted between said angle-section members for movement between a center and two opposing operative positions, means for causing pivotal movement of each angle-section member when said connecting means is displaced toward said angle-section member to thereby pivot only the angle-section member toward which the connecting means is displaced to an open position so as to unlock the frame and allow insertion of said cassette, said angle section members being mounted for pivotal movement in a plane parallel to the plane of insertion of said cassette, and means attached to said connecting means for causing displacement of said connecting means.
Claim 5
Dependent Claim
41 words
The holder according to claim 2 wherein said connecting means comprises a bar slidably mounted on said guide rail, a guide slot in said bar, and guide pins engaged in said slot so as to guide the displacement of said bar.
Claim 6
Dependent Claim
69 words
The holder according to claim 3 wherein said means for causing pivotal movement of said angle-section members comprises a first roller rotatably mounted on said angle-section member and a second roller mounted on said frame, said first and second rollers arranged for engagement with each other when said bar is displaced toward one of said angle-section members to thereby cause said angle-section member to pivot to an unlocked position.
