Abstract
Systems and devices to control linear, rotational, and/or arcuate motion are provided herein. In some examples, a pin system is configured for insertion in a door and/or door jamb, and to control motion of the door, such as a speed with which the door closes. In some examples, a hinge pin is configured to replace a conventional hinge pin 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.
Claims20
A device for controlling the motion of a door, comprising:
- a first hinge leaf that includes a chamber filled at least in part with a shear thickening fluid, the chamber further retaining a bushing and a plunger, wherein the bushing and plunger are connected to a screw, and
- a second hinge leaf that includes a nut and a portion of the screw, and
- wherein when the first hinge leaf is rotated, the screw rotates with respect to the nut such that the plunger moves vertically such that a piston connected to the plunger exerts pressure against the shear thickening fluid.
A device for controlling the motion of a door, comprising:
- a screw nut configured to receive a screw,
- a bushing connected to the screw, wherein rotation of the bushing relative to the screw nut causes the screw to move into or out from the screw nut, and
- a piston connected to the bushing, wherein the piston includes a shim including one or more slots, and a piston head including one or more slots, wherein the shim is configured to rotate with respect to the piston head to adjust alignment between the one or more slots of the shim and the one or more slots of the piston head,
- wherein movement of the screw causes the piston to move vertically such that the piston exerts pressure against a shear thickening fluid.
A device for controlling the motion of a door, comprising:
- a screw nut configured to receive a screw,
- a bushing connected to and receiving the screw, wherein rotation of the bushing relative to the screw nut causes the screw to move into or out from the screw nut, and
- a piston connected to the bushing, wherein movement of the screw causes the piston to move vertically such that the piston exerts pressure against a shear thickening fluid.
