Abstract

A weight-distributing exoskeleton capable of supporting and/or control the distribution of at least part of the weight of a protective garment and/or face shield proximate the knee of the user. The exoskeleton may include a plurality of leg structures, each leg structure including a knee joint or knee hinge configured to bear the load of the protective garment, and a foot member including a magnetic quick release mechanism configured to control quickly engage with and release from the leg structures. The weight of the protective garment and/or face shield is transferred to the floor such that the user bears little to no burden of carrying it.

Claims (10)

1. A knee rail system supporting a load on a wearer, comprising:

a knee rail mechanism comprising:

a knee rail,

an attachment point connected to a calf beam; and

a knee joint attached to a thigh beam, and forming therethrough an aperture through which the knee rail extends, such that the knee joint is disposed on and slidingly engages the knee rail on an end of the knee rail mechanism opposite the attachment point.

2. The knee rail system of claim 1 , wherein the knee rail system is configured to be positioned proximate to a knee of the wearer.

3. The knee rail system of claim 1 , wherein when the wearer is standing straight and not moving, the thigh beam and the calf beam are aligned, and that the knee joint is positioned on the knee rail on a posterior side of the calf beam to support an applied force from the load.

4. The knee rail system of claim 1 , wherein when the wearer's leg is lifted while in locomotion, the knee joint slides on the knee rail to a position on an anterior side of the calf beam.

5. The knee rail system of claim 1 , wherein the knee rail is configured to be disposed at angle from 10 degrees to 80 degrees relative to a y-axis of the wearer.

6. The knee rail system of claim 1 , further comprising a stopper configured to restrict the knee joint from bending.
