Apparatus to support and position crown molding and multi buildup wall and ceiling crown molding

摘要

An apparatus that supports and positions multiple build up ceiling and crown moldings during installation. The base of the apparatus is temporarily retained on the wall surface at its top through a centered 45 degree slot and a partially driven nail located approximately ⅞ inch down the wall surface vertically from the ceiling. The base has a centered dovetail track to accommodate a vertically moving member that slides up and down and can be locked at a desired position with a thumb screw that engages the dovetail track. The top of this vertically moving member has a flat pivoting support that adjusts to any angled crown mold profile and locked into position with tightening round knobs until molding is secured to ceiling and wall. The base's bottom has a sliding adjustment rod with boot to adjust parallel from the wall surface to accommodate multiple buildups of ceiling and wall crown moldings and a thumb screw to lock adjustment rod and boot in the proper position from the wall.

主权项

1. An apparatus for supporting and positioning various dimensions, lengths and configurations of wall and ceiling crown molding horizontally on a wall and ceiling surface during installation encompassing;
a flat base in which the top portion has a 45 degree slot that extends upwardly toward a centered hole that can be hung on a partially driven common nail ⅞ inch down vertically from the ceiling; a vertically attached centered dovetail track on the middle portion of a flat base with a supportive sliding body member that incorporates a vertically centered dovetail grove that slides on the dovetail track vertically centered on the middle portion of the flat base that can be locked in various vertical positions by means of a tightening thumb screw on its lower body; a top portion of the supportive sliding body member incorporates a pivoting flat upper body that conforms to the angled face of crown molding and two round locking knobs as a means to secure the pivoting flat upper body to the proper angled position of crown molding during the installation; a pivoting flat upper body that incorporates a dovetail track that accepts three sizes of extension attachments each having a dovetail grove and a tightening thumb screw as a means to secure the extension attachment to the dovetail track on the pivoting flat upper body; and an extension rod and connecting boot incorporated on the bottom portion of the flat base can be adjusted and locked into position by means of a tightening thumb screw to allow the apparatus to hang vertically parallel to the wall surface when installing multiple buildup of wall and ceiling crown moldings horizontally.
