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
An installation kit, comprising:
- a guide body;
- a drill bit bushing;
- and
- a locking collar;
- wherein the guide body is configured to be located over a desired place for a hole, the locking collar secures the bushing about a drill bit, and the drill bit is inserted into a hole in the guide body and activated to drill until the bushing engages a surface on the guide body.
A system for installing a device for controlling the closing of a door, comprising:
- a head unit that is configured to be installed in a doorjamb, wherein the head unit includes a cap that is connected to a piston and a chamber including a shear thickening fluid, wherein when the door is closed, the cap is moved into the head unit and the piston moves with respect to the shear thickening fluid, the shear thickening fluid resisting the movement of the piston depending on the force and speed with which the piston moves;
- and
- an installation kit including:
- a guide body;
- a drill bit bushing;
- and
- a locking collar;
- wherein the guide body is configured to be located at a desired place in the doorjamb, the locking collar secures the bushing about a drill bit, and the drill bit is inserted into a hole in the guide body and activated to drill until the bushing engages a surface on the guide body, a hole created in the doorjamb by the drill bit being sized to receive the head unit.
A system for installing a device for controlling the closing of a door, comprising:
- a strike that is configured to be installed in a door edge;
- a head unit that is configured to be installed in a doorjamb, wherein the head unit includes a cap that is configured to engage the strike and that is connected to a piston and a chamber including a shear thickening fluid, wherein when the door is closed and the cap engages the strike, the cap is moved into the head unit and the piston moves with respect to the shear thickening fluid, the shear thickening fluid resisting the movement of the piston depending on the force and speed with which the piston moves;
- and
- an installation kit including:
- a guide body;
- a drill bit bushing;
- a drill sleeve;
- and
- a locking collar;
- wherein the guide body is
- (i) configured to be located over a desired place on the doorjamb, and the locking collar secures the bushing about a drill bit, and the drill bit is inserted into a hole in the guide body and activated to drill until the bushing engages a surface on the guide body, a hole created in the doorjamb by the drill bit being sized to receive the head unit;
- and
- (ii) configured to be located over a desired place on the door edge, and the locking collar secures the bushing about the drill bit and the drill sleeve is inserted over a portion of the bushing, and the drill bit is inserted into the hole in the guide body and activated to drill until the sleeve engages the surface on the guide body, a hole created in the door edge by the drill bit being sized to receive the strike.
