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 hinge including a first hinge leaf and a second hinge leaf;
- a first spring within a first chamber of the first hinge leaf and connected to a plunger;
- and
- a second spring within a second chamber of the second hinge leaf and configured to contact a surface of the plunger opposite the first spring,
- wherein, when one of the first hinge leaf and second hinge leaf is rotated, a screw connected to the plunger rotates such that the plunger moves vertically within the first hinge leaf to vertically compress one of the first or second spring and vertically extend the other of the first or second spring;
- a plunger bushing connected to the screw by a pin, the plunger bushing configured to maintain a concentric position of the plunger such that the plunger travels along a central axis while moving with the screw and wherein the pin travels within one or more slots of the plunger bushing during vertical movement of the plunger.

A device for controlling the motion of a door, comprising:
- a first spring within a first chamber of a hinge and connected to a piston cartridge;
- a plunger connected to the piston cartridge;
- a screw connected to the piston cartridge and extending through a threaded portion of a nut, the nut fixed to, and configured to rotate with, a first hinge leaf of the hinge;
- and
- a second spring within a second chamber of the hinge and configured to contact the plunger opposite the first spring,
- wherein, when the first hinge leaf is rotated, the nut rotates with the first hinge leaf, which causes the screw to rotate and move vertically, causing the piston cartridge and the plunger to move vertically within the hinge to vertically compress one of the first or second spring and vertically extend the other of the first or second spring.

A device for controlling the motion of a door, comprising:
- a hinge including a first hinge leaf and a second hinge leaf;
- a first spring within a first chamber of the first hinge leaf and connected to a plunger;
- and
- a second spring within a second chamber of the second hinge leaf and configured to contact a surface of the plunger opposite the first spring, and
- a washer platform located in the second chamber and configured to be raised or lowered to change a distance the second spring can be compressed within the second chamber;
- wherein, when one of the first hinge leaf and second hinge leaf is rotated, a screw connected to the plunger rotates such that the plunger moves vertically within the first hinge leaf to vertically compress one of the first or second spring and vertically extend the other of the first or second spring.
