Abstract
Systems and devices to control rotational and/or arcuate motion are provided herein. In some examples, a hinge system is configured to replace a conventional door hinge and to control motion of the door. In some examples, a hinge system is configured to replace a conventional door hinge and to control motion of the door by employing a shear thickening fluid. In some examples, a door closure system is configured to replace a conventional door hinge and to control motion of the door by employing two opposing springs.
Claims21
A device for controlling the motion of a door, comprising:
- a housing that includes a nut and a chamber filled at least in part with a shear thickening fluid that is configured to have a decreasing viscosity in response to a first range of shear rates and an increasing viscosity in response to a second range of shear rates, wherein the second range of shear rates are greater than the first range of shear rates;
- a screw at least partially within the nut, the screw connected to a pin;
- a first hinge leaf to receive the pin such that the pin and the screw are configured to rotate with the first hinge leaf;
- and
- a second hinge leaf in a fixed position relative to the housing,
- wherein when the first hinge leaf is rotated, the screw rotates relative to the housing and the nut such that the nut moves vertically, forcing a piston assembly to exert pressure against the shear thickening fluid such that motion of the door transitions from a first velocity to a second velocity when the shear thickening fluid correspondingly responds to transitioning from the first range of shear rates to the second range of shear rates, wherein the second velocity is less than the first velocity.

- wherein the housing is supported by the pin and configured to extend from the second hinge leaf opposite the first hinge leaf.

A device for controlling the motion of a door, comprising:
- a housing that includes:
- a nut configured to move vertically within the housing;
- a cam connected to the nut and configured to move vertically within the housing in response to movement from the nut;
- and
- a chamber filled at least in part with a shear thickening fluid that is configured to have a decreasing viscosity in response to a first range of shear rates and an increasing viscosity in response to a second range of shear rates, wherein the second range of shear rates are greater than the first range of shear rates;
- a pin having a screw at one end, the screw at least partially within the nut;
- a first hinge leaf to receive the pin such that the pin and the screw are configured to rotate with the first hinge leaf;
- and
- a second hinge leaf in a fixed position relative to the housing,
- wherein when the first hinge leaf is rotated, the pin and screw rotate relative to the housing and the nut such that the nut moves vertically within the chamber, forcing the cam to move a piston assembly to exert pressure against the shear thickening fluid such that motion of the door transitions from a first velocity to a second velocity when the shear thickening fluid correspondingly responds to transitioning from the first range of shear rates to the second range of shear rates, wherein the second velocity is less than the first velocity.
