Abstract

A system for transferring objects into a device inside a controlled environment includes a winch, tool and carousel. The winch includes a drum, and wire arrangement configured to be reversibly wound onto the drum by a first drive. The tool is suspended below a distal end of the wire arrangement and configured to suspend an object. Both the tool and the object are sized to fit inside a device located below the winch. The carousel is connected to a second drive configured to rotate the carousel around a vertical axis, and includes a storage space centered at a first horizontal angle and a pass-through opening at a different second horizontal angle. The pass-through opening being large enough to pass the tool and the object as the wire arrangement is unwound from the drum thereby lowering the tool and object inside the device.

First claim

What is claimed is:

1 . An apparatus, comprising:
a housing; a handle at a top end of a housing; a central passage through the housing and the handle; and a floating element configured to move along an axis in the central passage through a range of positions bounded by an upper position and a lower position and including a neutral position; a flip-flop linkage comprising a sliding block constrained to move perpendicular to the axis and a coupler connected to the sliding block and to the floating element, wherein when the floating element is in the lower position the coupler positions the sliding block at a first perpendicular distance from the housing, when the floating element is in the upper position the coupler positions the sliding block at a different second perpendicular distance from the housing and the floating element protrudes through the handle, and when in the neutral position the coupler positions the sliding block at a maximum perpendicular distance from the housing; and a spring configured to bias the sliding block toward the housing and thereby, via the coupler, bias the floating element away from the neutral position; and a hook secured to the sliding block and configured to suspend an object therefrom.

2 . The apparatus of claim 1 , wherein the first perpendicular distance is less than the second perpendicular distance.

3 . The apparatus of claim 1 , wherein the first perpendicular distance is greater than the second perpendicular distance.

4 . The apparatus of clam 1 , comprising a second flip-flop linkage that functions identical to that of the flip-flop linkage and which is positioned opposite the flip-flop linkage about the floating element, and wherein a second coupler secured to a second sliding block of the second flip-flop linkage cooperates with the coupler to suspend the object there between.

5 . An apparatus, comprising:
a body comprising a groove configured to retain and move along a guide rail; a foot secured to the body and set apart from the body to form a gap therebetween, the foot comprising a receiving slot that extends along a first axis transverse to the groove and which comprises a cradle, wherein the cradle extends transverse to the first axis and is configured to receive and prevent lateral movement of a handle comprising a shape that cooperates with a shape of the cradle after the handle is moved laterally into the gap and then lowered and seated into the cradle, wherein a portion of the handle is disposed in the slot during the lateral movement into the gap; and a door in the gap configured to selectively move back and forth over the cradle, effective to prevent and permit respectively movement into the gap of a handle seated in the cradle.

6 . An apparatus, comprising:
a vertical support; a stand plate supported by the vertical support and comprising a receiving slot that extends in along an axis transverse to the vertical support, wherein the receiving slot is disposed between horizontal supports that are configured to receive and suspend an object that is moved lowered onto the horizontal supports, wherein a portion of the object is disposed in the slot during the lateral movement of the object.
