Abstract

A magnetic alignment fixture to temporarily hold a door latch striker in position relative to a door jamb while the alignment of the doors is adjusted. The magnetic alignment fixture includes a base plate of flexible material having an aperture for receiving and positioning the striker. The base plate magnetically holds the striker on the door jamb. The base plate may be moved by sufficient force applied against the striker in the plane parallel to the door jamb to overcome the magnetic force holding the base plate and thereby adjusts the position of the striker. The flexibility of the base plate allows the base plate to be flexibly peeled away from the door jam and the striker in a direction perpendicular to the door jamb after the striker is secured to the door jamb.

Claims

1. A magnetic alignment fixture for temporarily holding a striker in a position relative to a door jamb, the magnetic alignment fixture comprising:

a base plate of flexible material having an aperture sized to snugly receive the striker and positioning the striker in the plane parallel to the base plate; and

magnet means holding the base plate to the door jamb with the base plate parallel to the door jamb thereby positioning the striker on the door jamb and restricting motion of the striker in the plane of the surface of the door jamb, and the magnet means allowing the base plate to move with the striker when sufficient force is applied against the striker in the plane parallel to the door jamb to overcome the magnet means holding the base plate so that the base plate is moved by the striker whereby the position of the striker may be adjusted to a desired position where the magnetic alignment fixture holds the striker, and the magnet means further allowing the base plate to be flexibly peeled away from the door jamb and the striker in a direction perpendicular to the door jamb after the striker is secured in the desired position.

2. A magnetic alignment fixture for temporarily holding a striker in a position relative to a door jamb, the magnetic alignment fixture comprising:

a base plate of flexible material having an aperture sized to snugly receive the striker and positioning the striker; and

a plurality of magnets embedded in the base plate for holding the base plate to the door jamb thereby positioning the striker on the door jamb and restricting motion of the striker in the plane of the surface of the door jamb, and the plurality of magnets allowing the base plate to move with the striker when sufficient force is applied against the striker in the plane parallel to the door jamb to overcome the plurality of magnets holding the base plate so that the base plate is moved by the striker whereby the position of the striker may be adjusted to a desired position where the magnetic alignment fixture holds the striker, and the plurality of magnets further allowing the base plate to be flexibly peeled away from the door jamb and the striker in a direction perpendicular to the door jamb after the striker is secured in the desired position.

3. A magnetic alignment fixture for temporarily holding a striker in a position relative to a door jamb, the magnetic alignment fixture comprising:

a sheet of flexible magnetic rubber magnetically attachable to the door jamb and having an aperture sized to snugly receive the striker and positioning the striker, to thereby position the striker on the door jamb and restrict motion of the striker in the plane of the surface of the door jamb, and the sheet of flexible magnetic rubber allowing the sheet of flexible magnetic rubber to move with the striker along the door jamb when sufficient force is applied in the plane parallel to the door jamb to overcome magnetic attachment of the flexible magnetic rubber so that the sheet of flexible magnetic rubber is moved by the striker thereby the position of the striker may be adjusted to a desired position where the magnetic alignment fixture holds the striker and the flexible magnetic rubber further being flexibly peeled away from the door jam and the striker in a direction perpendicular to the door jamb subsequent to the attachment of the striker on the door jamb.
