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.

A positioning jig for locating drill holes or other targets in a workpiece on which the positioning jig is positioned. The positioning jig includes a pinion body and a pair of arms extending from the pinion body. The pair of arms are engaged with a pinion in the pinion body to provide a rack and pinion mechanism for centering the positioning jig on a workpiece. A jig body including at least one aperture is connected with the pinion body. The jig body may be translated with respect to the pinion body for locating the at least one aperture at a target point on the workpiece for drilling a hole or marking the workpiece.

A wall plate mounting system for attaching one end of a swing arm at a desired height and orientation to a vertical wall and attaches at the opposite end to a monitor and keyboard. The system includes an elongated body opened at one end with a center channel partially covered by two elevated flanges. The elongated body includes lateral flanges each with an upward extending ear. The ears are spaced apart and form a slot that communicates with the channel. Formed on the elongated body and under the slot are mounting holes. The system also includes an elongated template configured to slide freely inside the channel and under the ears. Formed on the elongated template is an elongated second slot and length measurement indices. During assembly, the elongated template is partially extended from the r channel formed on the elongated body at a desired length and locked together to form a jig. The jig is then moved to other walls and the mounting holes are marked so that mounting holes used with all wall plate mounting systems are the same height and proper orientation.

A system for mounting a door hinge to upper and lower mounting portions of front and rear pillars of a vehicle body being transferred along a vehicle transfer line. The system includes: a jig frame installed to reciprocate in a vehicle width direction through a driving unit on a base frame outside the vehicle transfer line; a rotation index installed on the jig frame and rotatable by a predetermined angle through a servomotor; a vertical rotation shaft formed as a polyhedron having a cavity and coaxially connected to a rotation center axis of the rotation index along an up and down vertical direction; and a pair of clamping units installed through a mounting plate to a base plate fixed to each side of the vertical rotation shaft, the pair of clamping units being disposed at upper and lower portions of the mounting plate and configured to clamp the door hinge.

The disclosure relates to a system and method for replacing an existing door while using the existing door frame structure. The system includes a mounting tool designed to locate a position of a door hinge on an existing door, and indicate a corresponding position for the door hinge on the replacement door without requiring substantial measurements or formation of hinge mortises. An edge mounting strip may be secured to the replacement door to complete the assembly and provide a flush surface with the door hinges along the end of the replacement door.

A tool or hinge positioning jig for creating hinge mortises including a hinge jaw having an hinge jaw first portion opposite and substantially parallel to an hinge jaw second portion, and an exterior first surface facing opposite an exterior second surface wherein at least one of the exterior first surface or the exterior second surface is laterally adjustably coupled to the hinge jaw, and wherein the hinge jaw first portion and hinge jaw second portion are capable of being aligned with first and second hinge edges, respectively, and the exterior first surface and exterior second surface are capable of being aligned with first and second workpiece edges, respectively.

A lift gate door having hinges installed for predetermined positioning into a vehicle. And a method of attaching a lift gate door to a vehicle while maintain proper tolerances. A first fixture holds a set of hinges in predetermined locations which correspond to assembly locations on a vehicle body. Hinges are temporarily attached to the fixture corresponding to the proper vehicle location. A second fixture holds the lift gate in a position which is a final installation position for attaching the lift gate to a vehicle. Self-adjusting moveable fastening nuts are provided in a set of holes in a hinge plate fastening area of the lift gate. The first fixture is moved into aligned orientation with the second feature and the hinges are attached to the lift gate with the fastener. The hinge is aligned in the proper installation orientation for maintaining the lift gate to vehicle gap in proper tolerances when the lift gate door with hinges is installed on the final vehicle.
