A 7' TORNE Y Big Patented May 16, 1950 SLIDER GUIDE RAIL Fred J. Burns, Saginaw, Mich., assignor to The Columbia Mills, Inc., New York, N. Y.
Application April 23, 1947, Serial No. 743,270
This invention relates to guide rails for slider members, and more particularly to a guide for maintaining the slats of the blind in predetermined relation with the window casing, preventing displacement due to wind or any other reason, and still provide suificient play or endwise movement so that the operation of the blind is free and easy.
One of the salient objects of the present invention is to provide a guide formed with quickly removable section which can be easily removed and replaced to permit removal and/or replacement of the slider members and slats for as sembly, repair, or for any other purpose.
Another object of the invention is to provide guide rails having rigid, easily removable sections, which will maintain accurate alignment when attached, which are interchangeable, right or left, and which are simple and easy to remove and replace in position.
A further object is to form the edges defining the slotted opening in the guide rails so as to accommodate and permit insertion of screws and screw securing means.
Still a further object is to provide removable channel-shaped guide sections which can be made up out of waste stock, which can be used either for inside or outside installations, and which naturally fit in proper assembled position and relation so that there is little possibility of incorrect or faulty installation.
A further object still is to provide a removable guide rail section which is formed and punched to accommodate screws for securing it in position, and which can be removed and/or replaced by merely backing off the screws sufficiently to permit removal of the section, the screws remaining in position at all times so the sections can be replaced and the screws tightened to hold the sections in accurate aligned relation.
To the accomplishment of the foregoing and related ends, said invention then consists of the means hereinafter fully described, and particularly pointed out in the appended claims, the annexed drawing and following description setting forth, in detail, certain means and one mode of carrying out the invention, such disclosed means and mode illustrating, however, but one of the various ways in which the principle of the invention may be used.
In the drawing:
Fig. 1 is a front-elevational view of a conventional blind including guide rails equipped with removable sections.
Fig. 2 is an enlarged, side-elevational view of the removable section showing the inner side of the guide rail.
Fig. 3 is a face view of one of the sections, the one edge being broken away to more clearly show the construction.
Fig. 4 is a fragmentary view showing the guide rail used as an outside installation.
Fig. 5 is a transverse-sectional view taken on the line 55 of Fig. 4.
Fig. 6 is a face view of an alternate construction.
Fig. 7 is a fragmentary, vertical, sectional view taken on the line 1-1 of Fig. 6.
To prevent Venetian blinds from swinging in the wind like a curtain, and striking or marring the window frame with the resultant noise and rattle, it is customary to provide slider guides on the ends of certain of the blind slats, and these slider guides slidably engage preferably channelshaped guide rails or track members C secured to the side rails of the window opening, so that they are adjustable with the blind, but in no manner interfere with the conventional operation thereof.
The guide rails, when installed, must be rigid and in accurate vertical aligmnent to eliminate any binding action; they extend from the bottom to the top of the window frame so as to eliminate any accidental displacement. Therefore, when the blind is installed and guide rails and slider guides are assembled and engaged, the only way to disengage the guides from the rails is to remove the entire guide rail together with the screws or other securing members, and this is not practical because of the time and labor involved; the possibility of misalignment when replacing, and the difiiculty of again engaging the slider guide with the guide rails, and I have, therefore, provided quickly and easily detachable rail sections R which are preferably located at the upper end of the guide rail, and which are readily removable so that the gliders, slats, etc. can be removed for cleaning, repair, replacement, or for any other purpose when desired.
Referring now to Figs. 1 and 2 of the drawings in which is shown the channel-shaped guide rails or tracks C formed with an elongated passage 8 therein, which is adapted to accommodate the slider guides G, one end of which is attached to a slat S, with the head H extending into the guide rails so that they freely slide therein when the blind is adjusted.
The rail proper comprises bottom, side, and wing sections 9, l0, and II respectively, and a plurality of openings l2 are provided in the bottom wall 9 of the guide rail as shown, said openings extending into the side walls In of the tracks as shown at M, and the opening I2 is of sufficient size to accommodate the screw I5 for securing the rail in position, while the opening I4 is of a size sufficient to permit passage of the screw head when the sections are removed and replaced.
The openings [2 are located in spaced relation and accommodate the screws l5, the wings H of the rails being punched or formed as at I6 to accommodate a conventional screw and screw driver (not shown), so that when it is desired to remove one of the sections R, the screws l5 are backed off sufiiciently to permit the sections to be shifted sidewise out of alignment with the main rail, the heads of the screws readily passing through the openings l4 so that the slider members, slats etc. can be readily removed.
To replace, it is merely necessary to move the section R sidewise so that the openings 14 register with the screws I5, and. when the section is in proper position, the screws are tightened so thatthe section forms an accurate continuation of the main guide rail.
In Figs. 4 and 5 of the drawing, I have shown the invention applied to an outside blind installation' in which the guide rails are mounted on brackets l "I which are secured to a-window frame W, small bolts l8 being substituted for screws, otherwise, the operation is identical.
In Figs. 6 and '7 of the drawings, I have shown a slightly modified construction in which the bottom walls of the traclrv sections are slotted as at [9, these slots opening into an enlarged area 28 that permits passage of the head of the screw l5 so that the sections can be shifted vertically and removed when. the screws are loosened; this can be readily assembled but has possibilities of incorrect installation.
From the foregoing description, it will be obvious that I have perfected a simple, practical, rigid and economical removable section for slider guide tracks which can be easily and quickly removed and replaced, and which can be formed of waste material.
What I claim is:
1. A Venetian blind including vertically disposed channel-shaped guide rails formed with opposed Wing sections on the free edges of the guide rail to provide an elongated slit of predetermined width therebetween, slider guides mounted on the slats of the blind with their heads non-removably engaging the wing sections of the guide rails for sliding engagement therewith when the blind is raised and lowered, and a, quickly removable section intermediate the length of each guide rail to permit removal or insertion of the slider guide when said section is removed.
2. The combination as defined in claim 1 in which screws are provided for securing the sectionsin position, said sections being formed with passages of a size to accommodate the shank of the screw to permit disengagement of the sections from the screws when said screws are loosened.
3. The combination as defined in claim 1 in which the guide rail is hollow and a continuous open passage is provided in the guide rail to permit sliding travel of the slider guides therein, screws mounted in the bottom wall of the guide rails and enlarged areas in the edges of the wings in direct horizontal alignment with said screws to permit insertion of a screw driver into said guide rail.
