said support plate being mounted to said base for adjustment relative to three spatial axes;
a lifting drive in said base for height-adjustment of said support plate;
a displacement drive in said base for selective coupling to said support plate for displacing said support plate in at least one of a longitudinal direction of said support plate and a transverse direction of said support plate substantially perpendicular to said longitudinal direction, when coupled to said support plate, and allowing floating displacement of said support plate when uncoupled from said support plate;
said support plate being mounted to said base for pivoting around a canting axis and pivoting around a tilting axis parallel to said transverse direction;
a pivoting drive in said base connected to said support plate for pivoting said support plate around at least one of said canting axis and said tilting axis; and
said lifting drive, said displacement drive and said pivoting drive being coupled together for pivoting said support plate around a predetermined isocenter of said support plate.
2. The improvement of claim 1 wherein said pivoting drive is capable of pivoting said support plate around at least one of said spatial axes only when said displacement drive is coupled to said support plate.
3. The improvement of claim 1 wherein said support plate has a variable configuration.
4. The improvement of claim 3 wherein said support plate is variably configurable to form a support plate adapted for angiography, a flat operating room support plate, an operating room support plate having at least one bend therein, and a support plate adapted for computed tomography.
5. The improvement of claim 1 comprising a set of interchangeable support plates, including said support plate with said radiation-transparent region.
6. The improvement of claim 5 wherein said set of support plates includes an angiography support plate, an operating room support plate, and a computed tomography support plate.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
What is claimed is:
1. A connector connecting device comprising:
a first connector;
a slide member slidably mounted on said first connector;
a lever pivotally mounted on said first connector, and being rotatable in accordance with a slide movement of said slide member;
a second connector connectable with said first connector including an engagement portion engageable with said lever;
a holding mechanism which holds said lever by engagement with said first connector when said slide member is kept in a drawn-out condition relative to said second connector;
wherein an inserting-drawing force acting between said first and second connectors is reduced by an operating force, applied to said slide member, is converted into a rotational of said lever.
2. A connector connecting device according to claim 1, wherein said second connector includes a holding cancellation member for canceling said engagement of said lever when said first connector is inserted into or drawn from said second connector.
3. A connector connecting device according to claim 1, wherein a line, which connects an axis of said lever and a force-applying point of said lever at which a force is applied to said lever from said slide member, is disposed substantially perpendicular to a slide direction of said slide member when said lever begins to engage with said engagement portion.
4. A connector connecting device according to claim 1, wherein said first connector includes a pair of support portions, spaced a predetermined distance from each other, for pivotally movably supporting said lever disposed between said pair of support portions, said lever includes slanting surfaces brought into sliding contact with peripheral edges of head portions of said support portions when said lever is inserted into a gap between said support portions.
5. A connector connecting device according to claim 1, wherein said lever is engaged with said engagement portion when said lever is pivotally moved a predetermined angle from a rotation start position in accordance with said slide movement.
6. A connector connecting device according to claim 1 further comprising a terminal holder mounted on said first connector to prevent a terminal from being withdrawn from said first connector, wherein said terminal holder projects into a path of said slide movement when said terminal holder is incompletely mounted on said first connector.
7. A connector connecting device according to claim 1, wherein said first connector is one of a female connector and a male-connector, said second connector is the other of said female connector and said male connector.
8. A connector connecting device comprising:
a first connector;
a slide member slidably mounted on said first connector;
a lever formed in Y-shape defining two tines and a base portion, pivotally mounted on said first connector through a center portion where said tines is connected to said base portion, and being rotatable in accordance with a slide movement of said slide member; and
a second connector connectable with said first connector including an engagement portion engageable with said lever;
wherein one end of said tines is engaged with said engagement portion when said first connector is inserted in said second connector, the other end of said tines is engaged with said engagement portion when said first connector is drawn from said second connector, said base portion receives a force applied from said slide member, and
wherein an inserting-drawing force acting between said first and second connectors is reduced by an operating force, applied to said slide member, is converted into a rotational of said lever.
9. A connector connecting device according to claim 9, wherein said engagement portion is projected from said second connector in a direction perpendicular to a slide direction of said slide member and defines a lower surface engaged with said one end of said tines when said first connector is inserted in said second connector and an upper surface engaged with the other end of said tines when said first connector is drawn from said second connector.
10. A connector connecting device according to claim 8 further comprising a holding mechanism which holds said lever by engagement with said first connector when said slide member is kept in a drawn-out condition relative to said second connector.
11. A connector connecting device according to claim 10, wherein said second connector includes a holding cancellation member for canceling said engagement between said lever and said first connector when said first connector is inserted into or drawn from said second connector.
12. A connector connecting device according to claim 8, wherein a line, which connects an axis of said lever and a force-applying point of said lever at which a force is applied to said lever from said slide member, is disposed substantially perpendicular to a slide direction of said slide member when said lever begins to engage with said engagement portion.
13. A connector connecting device according to claim 8, wherein said first connector includes a pair of support portions, spaced a predetermined distance from each other, for pivotally movably supporting said lever disposed between said pair of support portions, said lever includes slanting surfaces brought into sliding contact with peripheral edges of head portions of said support portions when said lever is inserted into a gap between said support portions.
14. A connector connecting device according to claim 8, wherein said lever is engaged with said engagement portion when said lever is pivotally moved a predetermined angle from a rotation start position in accordance with said slide movement.
15. A connector connecting device according to claim 8 further comprising a terminal holder mounted on said first connector to prevent a terminal from being withdrawn from said first connector, wherein said terminal holder projects into a path of said slide movement when said terminal holder is incompletely mounted on said first connector.
