Abstract
Disclosed are systems and devices for controlling the closing of a door. A head unit is to be installed in a doorjamb, comprising a chamber filled at least in part with a shear thickening fluid. A piston is connected to a cap and configured to exert pressure against the shear thickening fluid in response to a force applied to the cap. The systems and devices provide an adjustable design that resists door slamming and aggressive closure, serving as a safety device as well as noise, damage and pet control around doors (preventing closure if desired). An install kit provides exact location, depth control and guide to place over the head unit to tap it into place with a hammer.
Claims20
A device for controlling the motion of an object, comprising:
- a head unit that includes a chamber filled at least in part with a shear thickening fluid;
- a plunger in the head unit that is connected to a cap and a piston head, the piston head having at least one slot and being positioned in the chamber of the head unit;
- a shim that includes a D-shaped hole and at least one slot;
- and
- a plug having a D-shaped portion that is received in the D-shaped hole of the shim such that the shim does not rotate with respect to the plug and an end portion that is connected to the plunger;
- wherein the piston head and shim are configured to both move axially in the chamber with respect to the shear thickening fluid in response to a force applied to the cap by an object and wherein the shim is configured to be rotated with respect to the piston head.
A device for controlling the motion of an object, comprising:
- a head unit that includes a chamber filled at least in part with a shear thickening fluid;
- a plunger in the head unit that is connected to a cap,
- a bushing and a spring in the head unit, wherein the spring is configured to provide mechanical resistance between the cap and the bushing in response to a force applied to the cap;
- a piston head connected to the plunger and positioned in the chamber of the head unit, the piston head having at least one slot;
- a shim that includes a D-shaped hole and at least one slot;
- and
- a plug having a D-shaped portion that is received in the D-shaped hole of the shim such that the shim does not rotate with respect to the plug and an end portion that is connected to the plunger;
- wherein the piston head and shim are configured to both move axially in the chamber with respect to the shear thickening fluid in response to a force applied to the cap by an object and wherein the shim is configured to be rotated with respect to the piston head.
A device for controlling the motion of an object, comprising:
- a head unit that includes a chamber filled at least in part with a shear thickening fluid;
- a plunger in the head unit that is connected to a cap,
- a bushing and a spring in the head unit, wherein the plunger extends through the bushing and spring, and the spring is configured to provide mechanical resistance between the cap and the bushing in response to a force applied to the cap;
- a piston head that receives a portion of the plunger, engages a flange on the plunger, and that is positioned in the chamber of the head unit, the piston head having at least one slot;
- a shim that includes a D-shaped hole and at least one slot;
- and
- a plug having a D-shaped portion that is received in the D-shaped hole of the shim such that the shim does not rotate with respect to the plug and an end portion that is received in the plunger;
- wherein the piston head and shim are configured to both move axially in the chamber with respect to the shear thickening fluid in response to a force applied to the cap by an object and wherein the shim is configured to be rotated with respect to the piston head.
