Abstract
An adjustable shim is described for attachment to a pre-hung door or a rough opening. The adjustable shim may include a base bracket for mounting the adjustable shim to the pre-hung door or the rough opening, an inner shim, an outer shim, and a first actuator operably attached between the base bracket and the inner shim. At least one of the inner shim and the outer shim is tapered. Rotation of the first actuator translates the inner shim substantially linearly relative to the outer shim, thereby adjusting a combined height of the inner shim and the outer shim.
Claims20
An adjustable shim, the adjustable shim comprising:
- a base bracket configured to mount the adjustable shim to a pre-hung door or a rough opening;
- an inner shim;
- an outer shim;
- a first actuator operably attached between the base bracket and the inner shim;
- a plumb adjustment bracket slideably attached to the base bracket and configured for attachment to a rough opening frame that defines a rough opening;
- and
- a second actuator configured to convert rotational motion of the second actuator into linear motion, sliding the plumb adjustment bracket relative to the base bracket along a direction into and out of the rough opening,
- wherein at least one of the inner shim and the outer shim is tapered,
- wherein rotation of the first actuator translates the inner shim substantially linearly relative to the outer shim, thereby adjusting a combined height of the inner shim and the outer shim.
An adjustable shim, the adjustable shim comprising:
- a base bracket configured to mount the adjustable shim to a pre-hung door or a rough opening;
- an inner shim;
- an outer shim;
- a first actuator operably attached between the base bracket and the inner shim;
- and
- at least one strap rotatably attached to the base bracket for attaching the adjustable shim to a rough opening frame,
- wherein at least one of the inner shim and the outer shim is tapered,
- wherein rotation of the first actuator translates the inner shim substantially linearly relative to the outer shim, thereby adjusting a combined height of the inner shim and the outer shim.
A pre-hung door, comprising:
- a pair of vertical frame members,
- a header spanning across a top of the vertical frame members;
- a threshold spanning across a bottom of the vertical frame members;
- a door panel hinged to one of the vertical frame members;
- and
- at least one adjustable shim, the at least one adjustable shim comprising:
- a base bracket configured to mount the adjustable shim to a pre-hung door or a rough opening;
- an inner shim;
- an outer shim;
- and
- a first actuator operably attached between the base bracket and the inner shim,
- wherein at least one of the inner shim and the outer shim is tapered,
- wherein rotation of the first actuator translates the inner shim substantially linearly relative to the outer shim, thereby adjusting a combined height of the inner shim and the outer shim,
- wherein a receiving recess is formed in a back face of at least one of the vertical frame members into which a respective one of the at least one adjustable shim is mounted.
