Abstract

A crown molding raising, positioning and holding jig (2). Attached to a handle meant to fit an adjustable extension pole (1). With a wall plate that has a thin fiberglass extension (5) to prevent the molding from falling, and a lip (9) to rest the bottom edge of the molding on. With shims and extensions to accommodate different size and shape moldings. With a non slip base to hold the extension pole.

BACKGROUND OF INVENTION

1. Field of Invention
This invention is related to raising positioning and holding crown molding safely, easily, and quickly. Once in place it leaves a person hands free to check, adjust, and attach the molding. It is to provide a narrow strong back lip to prevent the molding from falling off while not holding it too far from the wall, a thickness of less than ⅛″ is ideal. It is to provide flexibility in the size, shape, and face angle of molding that can be handled. It is to position the molding with a rigid 45 degree angle between the wall plate and the molding face. It is to be easily attached to a standard sized adjustable length extension handle. It is to provide slip free stable bases for the extension poles used.
2. Prior Art
Crown molding installers currently use crews of people to install molding, with one person putting the molding into its final position and nailing while one or more persons hold the other end of the molding. There is no raising and install jig in common use, that allows easy, quick, safe use, and once in place, hands free checking, positioning, and attaching of the molding.

SUMMARY

In accordance with the present invention, a crown molding raising, and install jig with a nonslip base. A jig that is easy, safe, quick to use, and stable enough to be hands free once in place.

DRAWINGS—NUMERALS

1 Handle, from a paint roller handle, strapped onto the jig assembly.
2 Body of jig, shaped to angle the handle and the attached extension pole away from the wall.
3 Tine of jig, predrilled to attach extensions, and angle changers. Set to rest face of molding at 45 degrees to wall plate.
4 Strapping to securely hold the handle to the jig assembly.
5 Wall plate back lip, thin strong extension that goes flat against the wall behind the molding.
6 Wall plate, attaches to back of jig, has a lip to rest the bottom edge of the molding on, has a thin flat fiberglass extension that goes flat against the wall behind the molding. Part that contacts the wall is coated with urethane caulk to prevent slippage.
7 Side of wall plate that connects to the jig, or to a shim between the wall plate and the jig.
8 Wall plates and shims are predrilled for ease of use.
9 Wall plate lip the bottom edge of the molding rests on.
10 Hole in center of base slightly larger than end of pole to provide a stability to the pole and attached assembly.
11 Eye hooks for securing the pole to the base.
12 Ceiling.
13 Molding.
14 Adjustable length extension pole.
15 Base, goes on floor, holds extension pole.
16 Painters tape to mark stud locations, and to mark location where bottom of molding goes.
17 Standard molding, most common in use today, with 45 degree face angle.
18 Angle between wall plate and face of molding.

DETAILED DESCRIPTION

FIGS. 1A and B show a jig meant to be attached to an adjustable extension pole to raise position, and hold in place molding, once in place to be stable, safe, and hands free to check, adjust, and attach the molding.
FIGS. 2 and 3 show the wall plate that attaches to the back of the jig. It has a fiberglass extension that prevents the molding from falling,and a lip to rest the bottom of the molding on. It is predrilled to easily attach to the jig. The face that contacts the wall is coated with a urethane caulking to minimize slippage.
FIGS. 4 and 5 show a shim that can be placed between the wall plate and the jig to provide a wider lip for the molding to rest on.
FIGS. 6 through 11 show extensions that can be place between the tines of the jig to allow for different size moldings. They are predrilled for the tines.
FIGS. 12 through 17 Show angle change extensions that can allow the use of molding with 38 degree and 52 degree face angles. These are left undrilled, to allow flexibility.
FIGS. 18 and 19 show the base, it has a hole for the pole, that is tapered forward towards the wall, but otherwise fits snug to prevent tipping. The bottom is coated with urethane caulk to prevent slippage on glossy floors.
FIG. 20 shows three assemblies attached to three poles in three bases. The molding is set in place, safe stable and hands free.

Operation

Prior to use, the room must be prepped, all furniture and wall art removed. A stud finder is used to locate all studs, and they are marked with painters tape approximately 1-2 inches below where the bottom of the molding will be attached to the wall. A short piece of molding is held in place above the tape such that the installer has a good view of its positioning, and the painters tape is moved to just below the bottom of the molding. This forms a positioning line and stud locater around the entire room. The jigs are meant to be assembled to fit the size of molding being used, mounted on adjustable extension poles, and set against the wall in groups of two or three. The poles are fit inside their bases, and are adjusted to one foot from the ceiling. Using a ladder, The molding is set in the jigs, then the poles are adjusted to the ceiling. Once all the jigs are fit snuggly to the ceiling, the installer is hands free to check, adjust, and attach the molding. The installer starts on one end and uses the painters tape as a guide to accurately position the molding while attaching it with a nail gun. As the installer gets to within 2 feet of an install jig, the jig is removed.

Claims

1. A crown molding raising positioning and holding jig with a wall plate cut 45 degrees from the molding face.

2. A pole base made to narrowly fit the end of the pole, so as to prevent motion of the pole, the base is fitted with eye hooks which have a hooking mechanism to the pole. The bottom of the base is coated with urethane caulk to prevent slippage on glossy surfaces.

3. When used in a set of three assemblies, each with a separate extension pole and base, one person can easily, and safely raise and position a 16 foot long piece of molding. Then with the molding held in place, the installer is hands free, length and fit can be checked, and attachment begun.
