Abstract

A door and window frame adjusting shim sized to fit all common interior or exterior prehung doors and framed windows, preferably factory pre-mounted to the prefabricated door or window casing, comprised of a flat mounting plate and two attached interlocking nested wedge shaped portions, to provide a carpenter or homeowner with a functional, reliable and inexpensive installation shim method, the adjusting shim permits rapid positioning of the door or window, and is especially useful when installing multiple doors and windows into a building.

Claims

1. An adjustable two-part wedge shim spacer, affixed in combination with a jamb of a prefabricated building closure, comprising:

a pair of tapered wedge shims comprising, a movable wedge shim and a fixed wedge shim each having a sloped face and two side faces and presenting a top contact face and a bottom face, each wedge shim lying against one another upon the contact face, with the sloped face of one said shim going in the direction opposite the other said shim, each said shim in telescopic cooperative relation with the other said shim, and the width of said shims approximate the width of said closure jamb; and

a widened, flat, thin mounting plate permanently attached to the bottom face of the fixed wedge shim, the fixed wedge shim is centered longitudinally and latitudinally upon said mounting plate, and said mounting plate extends the fall width of said closure jamb, said mounting plate extends substantially beyond both ends of the length of said fixed wedge shim, and said mounting plate has directional mounting identification markings presented thereon; and

a pair of finger tabs, extending at right angle to the side faces of the movable wedge shim, said finger tabs are located at the thickened end of said moveable wedge shim; and

a parallel central guide channel, longitudinally extending the entire length of the contact face of the fixed wedge shim, and a complementary longitudinally extending parallel channel follower on the contact face of the movable wedge shim; and

a duality of longitudinal guide furrows adjacent to said guide channel on the contact face of the fixed wedge shim, and correlative guide furrow followers on the contact face of the movable wedge shim, said guide furrow followers each have a lug portion projecting therefrom, and said guide furrow followers engage the guide furrows by a snap-fit interlocking coupling of the lug portions to hold the movable wedge shim overlapping the fixed wedge shim, wherein the movable wedge shim is slidably movable, and securely held upon the contact face of the fixed wedge shim.

2. The wedge shim spacer according to claim 1, wherein the wedge shim spacer is affixed completely intact onto the jamb of the prefabricated building closure during manufacture of the building closure.
