Spacesuit Mobility Joints
View pageUS Patent:
40914640, May 30, 1978
Filed:
Dec 23, 1976
Appl. No.:
5/753965
Inventors:
Hubert C. Vykukal - Los Altos CA
Assignee:
The United States of America as represented by the Administrator of the
National Aeronautics and Space Administration - Washington DC
National Aeronautics and Space Administration - Washington DC
International Classification:
A62B 1700
US Classification:
2 21A
Abstract:
Pressure suit mobility joints for use in interconnecting adjacent segments of an hermetically sealed spacesuit in which low torques, low leakage and a high degree of reliability are required. Each of the joints is a special-purpose joint characterized by substantially constant volume and low torque characteristics and includes linkages which restrain the joint from longitudinal distension and includes a flexible, substantially impermeable diaphragm of tubular configuration spanning the distance between pivotally supported annuli. The diaphragms of selected joints include rolling convolutions for balancing the joints, while various joints include wedge-shaped sections which enhance the range of motion for the joints.

US Classification:
2 21A
Abstract:
For use in hard space suits and the like, a joint between the torso covering and the upper arm covering (i. e. , shoulder) or between the torso covering and upper leg covering (i. e. , hip) is disclosed. Each joint has an outer covering and a inner covering. The outer covering has plural preferably truncated toroidal sections decreasing in size proceeding outwardly. In one embodiment at each joint there are two bearings, the first larger than the second. The outer race of the larger bearing is attached to the outer edge of the smaller end of each section and the inner race of the larger bearing is attached to the end wall. The inner race of the smaller bearing is attached to the end wall. The outer race of the smaller bearing is attached to the larger end of the next section. Each bearing has appropriate seals.

US Classification:
36 92
Abstract:
A walking boot assembly particularly suited for use with a positively pressurized spacesuit, including a bootie adapted to be secured to the foot of a wearer, an hermetically sealed boot for receiving the bootie having a walking sole, an inner sole and an upper portion adapted to be attached to an ankle joint of a spacesuit, a protuberance projected from the bootie and received within a recess formed in the inner sole of the boot for positioning the bootie relative to the boot, and releasable latching means for latching the protuberance in a received relationship with the recess.
Shoulder And Hip Joint For Hard Space Suits
View pageUS Patent:
45947341, Jun 17, 1986
Filed:
Dec 20, 1984
Appl. No.:
6/684192
Inventors:
Hubert C. Vykukal - Los Altos CA
Assignee:
The United States of America as represented by the Administrator of the
National Aeronautics and Space Administration - Washington DC
National Aeronautics and Space Administration - Washington DC
International Classification:
A62B 1700
F16L 1118
F16L 1118
US Classification:
2 21A
Abstract:
For use in hard space units and the like, shoulder and hip joints comprising three serially-connected truncated spherical sections, the ends of which converge. Ball bearings between the sections permit relative rotation. The proximal end of the first section is connected to the torso covering by a ball bearing and the distal end of the outermost section is connected to the elbow or thigh covering by a ball bearing. The sections are equi-angular and this alleviates lockup, the condition where the distal end of the joint leaves the plane in which the user is attempting to flex. The axes of rotation of the bearings and the bearing mid-planes are arranged to intersect in a particular manner that provides the joint with a minimum envelope. In one embodiment, the races of the bearing between the innermost section and the second section is partially within the inner race of the bearing between the torso and the innermost spherical section further to reduce bulk.
Cooling System For Removing Metabolic Heat From An Hermetically Sealed Spacesuit

International Classification:
A62B 714
US Classification:
1281427
Abstract:
An improved cooling and ventilating system for removing metabolic heat, waste gases and water vapor generated by a wearer of an hermetically sealed spacesuit. The cooling system is characterized by a body suit having a first circuit for simultaneously establishing a cooling flow of water through the thorax and head sections of the body suit including circulation patches mounted in the thorax section and head section of the body suit, a second circuit for discharging a flow of gas throughout the spacesuit and a disconnect unit for coupling the circuits with a life support system externally related to the spacesuit.

Space Suit Sizing Device
View pageUS Patent:
54093317, Apr 25, 1995
Filed:
Apr 5, 1993
Appl. No.:
8/053940
Inventors:
Hubert C. Vykukal - Gold River CA
Assignee:
The United States of America as represented by the National Aeronautics
and Space Administration - Washington DC
and Space Administration - Washington DC
International Classification:
F16B 710
US Classification:
403109
Abstract:
A space suit sizing device using a ball nut and screw drive mechanism to shorten and lengthen components of a space suit. The device includes a rotatable member having an outer race formed on an inner surface thereof, and a translatable member having an inner race formed on an outer surface thereof. A plurality of recirculating balls are located in a space defined by the inner and outer races. As the rotatable member is rotated by hand, the translatable member is caused to move in and out of the rotatable member. Since one component of the space suit is connected to the translatable member, the length of this component varies in accordance with the position of the translatable member.
Pressure Suit Joint Analyzer

43110550, Jan 19, 1982
Filed:

Appl. No.:
6/168943
Inventors:

International Classification:
G01L 300
US Classification:
7386208
Abstract:
The invention pertains to a measurement system for simultaneously measuring torque and angular flexure in a pressure suit joint. One end of a joint (11) under test is held rigid. A torque transducer (31) is pivotably supported on the other movable end of the joint. A potentiometer (36) is attached to the transducer (31) by an arm (33). The wiper shaft (37) of the potentiometer is gripped by a reference arm (41) that rotates wiper shaft (37) the same angle as the flexure of joint (11). A signal is generated by the potentiometer (36) which is representative of the joint flexure. A compensation circuit (67) converts the output of the transducer (31) to a signal representative of joint torque.
