I CLAIM
1. An interface between an orbital replacement unit and an end effector having
end effector clamping jaws, comprising:
a) two substantially rigid body parts, each body part having an upper
ramp, a lower ramp, and a reduced waist portion between the upper and lower
ramps,
said waist portion having side faces, and wherein
b) the upper and lower ramps of each body portion are inclined inwardly
towards the side faces of the waist portion which converge outwardly to form
laterally
extending, substantially V-shaped clamping faces, whereby,
c) with the two body parts attached to an orbital replacement unit with the
substantially V-shaped clamping faces extending outwardly in opposite
directions
from one another,
d) the inwardly inclined ramps will effect vertical engagement of the end
effector clamping jaws, with the orbital replacement unit, against
dislodgement by
vertical loads, applied therebetween, and
e) the substantially V-shaped clamping faces will effect lateral clamping
engagement of the end effector clamping jaws to the orbital replacement unit,
against
dislodgement by a torque applied therebetween.
2. An interface as claimed in claim 1, wherein the reduced waist portions
together form a square cross-section with the V shaped clamping faces
diagonally
spaced at 1800 with respect to one another.
3. An interface as claimed in claim 1, wherein said body parts are a pair of
discrete segments each having one of said V-shaped clamping face formed
thereon,
said segments being attachable to opposite sides of an orbital replacement
unit with
the V-shaped clamping faces oppositely disposed.
4. An interface as claimed in claim 1, further comprising torque transmitting
latch means, operable by the end effector clamping jaws, for releasably
attaching said
body parts to a system in which an orbital replacement unit is to be mounted,
said
latch means comprising detent means mounted on each of the body parts for

movement between an extended position projecting laterally front the body part
on
which it is mounted and a retracted position that is located inwardly, from
the
extended position, towards said body part and resilient means for urging the
detent
means towards the said extended position.
5. An interface as claimed in claim 4 wherein the apex of each V-shaped
clamping face forms a longitudinally extending ridge and said latch means
further
comprises; a latch actuator member connected to said detent means for movement
therewith and extending parallel to the longitudinally extending ridge
associated
therewith, each latch actuator member being movable, from a first position
disposed
laterally outwardly from its associated ridge, when said detent means is in
said
extended position, to a second position located inwardly from its associated
ridge,
when the associated detent means is in said retracted position, such that
displacement
of each latch actuator member from the first position to the second position,
when
each latch actuator member is engaged by the end effector clamping jaws moving
into
engagement with the clamping faces, will cause both the detent means to move
from
their extended positions to their retracted positions.
6. An interface as claimed in claim 5 wherein the reduced waist portions
together
form a square to provide first and second sets of oppositely disposed ridges,
cross-
section each latch actuator means being associated with one of the ridges of
the first
set thereof, the ridges of the second set thereof being spaced from the latch
actuator
means so as to be engageable by the end effector clamping jaws.
