Abstract
A gauge for accurately and quickly positioning window-shade brackets by retaining a bracket on the gauge, by magnetic attraction, at a predetermined distance from the top of the window frame to afford adequate room for the shade in its fully rolled position, while this position is marked by an instrument extending through an aperture in the bracket and a slot in the gauge along which the bracket is movable in the course of its positioning. Lineal scales on the gauge facilitate the measuring of the diameter of the window-shade in fully rolled position and the setting of the brackets on the gauge correspondingly. Apertures on the gauge are provided to render it a convenient tool for winding the springs of the window-shade rollers.
Claims13
A guage for determining the proper mounting locations for apertured magnetically attracted mounting brackets for roller window-shades within window frames, comprising,
- a. a substantially flat elongated guide member adapted to be positioned vertically on a window frame,
- b. a track of uniform width on the outer face of said guide member comprised of a pair of elongate supports of paramagnetic material with a longitudinal slot therebetween coincident with the locus of the free movement of a central aperture in the bracket in the course of its freely adjustable movement along the track to a position providing adequate clearance for the fully rolled-up window-shade,
- c. a lineal scale adjacent to one of said supports for noting the position of said central aperture relative thereto while said bracket is retained in a vertical plane solely by the force of magnetic attraction between said track and bracket, and
- d. a projection extending laterally from the outer face of said guide member serving both as a handle for the latter as well as a stop for gauging the diametral dimension of the rolled up shade to provide a setting point for a marking impression on said window frame through an aperture of the bracket and the longitudinal slot of said track.
A gauge for determining the proper mounting locations for apertured magnetically attracted mounting brackets for roller window-shades within window frames, comprising
- a. a substantially flat elongated guide member of sheet material having a handle extending transversely from one end thereof and adapted to be positioned vertically on a window frame,
- b. a constant-width of track of magnetized material beyond said handle on the outer face of said guide member with a medial longitudinal slot in the track for retaining a mounting bracket thereon solely by magnetic attraction while permitting free movement of the latter therealong during coincidence of the central aperture in the bracket with said slot,
- c. a lineal scale on the inner face of said guide member adjacent to said slot, starting from the handle end to the opposite free end, said scale adapted to have the pin of the window-shade roller indicate the radius of the fully rolled shade when the shade is in abutment with the handle, and the pin extends through the central aperture in the bracket and said slot, and
- d. a second lineal scale on the outer face of said guide member starting from said opposite free end of the latter for gauging an incremental setting for the bracket in excess of the radial dimension of the shade, which setting is adapted to be marked by a marking instrument extending through an opening in the bracket and slot therebelow to the body of the window frame.
