BOTTOM RAIL FOR VENETIAN BLINDS Filed June 22, 1936 1N VENTOR.
BYWIW*W ATTORNEY} Patented May 11, 1937 UNITED STATES PATENT OFFICE BOTTOM RAII FOR VENETIAN BLINDS George A. Grassby, Jr., Sturgis, Mich, assignor to Kirsch Company, Sturgis, Mich.
Application June 22, 1936, Serial No. 86,594
11 Claims. (0]. 156-17) This invention relates to Venetian blinds and more particularly to all metal bottom rails for Venetian blinds. It has for its objects:
First, the production of a. new and improved 5 all metal bottom rail for Venetian blinds which erly positioned and fastened in place, thereby eliminating the necessity for cutting or stamping holes in the body of the bottom rail.
Fourth, to provide such a sheet metal bottom rail on which the slats of the blind are picked up as the blind is raised and in which the increased weight of the slats assists in firmly holding the lift cord attaching members in position.
Fifth, to provide such a bottom rail which may be easily and inexpensively maintained.
Sixth, to provide such a bottom rail with a simple and inexpensive clip for firmly attaching the ladder tapes thereto.
Other objects and advantages pertaining to details and economies of construction and operation will appear from the description to follow. Preferred embodiments of my invention are illustrated in the accompanying drawing, in which:
Fig. 1 is an elevation view of a portion of a blind having my improved bottom rail thereon.
Fig. 2 is a perspective view of my bottom rail.
Fig. 3 is a detail sectional view through my bottom rail showing the method of attaching the lift cords and the ladder tapes.
Fig. 4 is a detail sectional view taken on line 5-4 of Fig. 3, illustrating a further detail of the means for fastening the lift cords to the rail.
Fig. 5 is a detail sectional view showing the method of fastening the lift cord or other fixtures in position in my bottom rail.
Fig. 6 is a detail perspective view showing a lift cord attaching fixture:
Fig. 'I is a detail view showing a similar fixture for use in connection with multiple lift blinds.
Fig. 8 is a detail perspective view of a fixture for fastening the blind down when it is completely lowered.
Fig. 9 is a detail perspective view of the clip used for fastening the ladder tapes in position on the blind.
In the drawing, I represents a usual Venetian blind having slats 2 and ladder tapes 3 which have a front section 4 which extends on one side of the bottom rail and a rear section 5 which extends on the other side thereof. 6 is my improved bottom rail which is formed of a strip of sheet metal. Aluminum or aluminum alloys are especially advantageous for this purpose because of their light weight, although any sheet metal can be employed. The bottom rail 6 is formed of a strip of sheet metal having its sides I bent up and recurved back over the base 8 of the strip. The edges 9 of the recurved portions 1 are spaced from one another to form a central channel Ill in the rail for receiving and concealing lift cord fixtures or the like. The edges 9 are also spaced from the base or bottom 8 of the rail, as is best seen in Fig. 3, to provide a space or way II to receive the base of the lift cord fixtures.
It will be noted that my improved bottom rail maybe formed of a single strip of sheet metal without any perforations for fastening lift cords or the like. This makes it possible to produce long lengths of the formed strips which can be cut to length, thus making it possible to save considerable in the manufacture and installation of blinds because it is not necessary to form many different lengths of bottom rail to accommodate the different length or width of blind which must be supplied to the retail trade.
I attach the lift cords l2 by means of lift cord fixtures l3. These are preferably made as metal stampings and consist of an arched portion it having rounded flanged edges I 5 having a base [6 which in this instance consists of four arms II which extend laterally from the bottom of the fixture. The base slides into the way or space H between the edges 9 of the recurved portions 1 of the bottom rail and the base or bottom 8 of the bottom rail.
In assembling the blind, the fixtures l3 are slid to the proper position and a punch press is employed to make indentations l8, as shown in Fig. 5, in the edge of the recurved portion 1 of the metal bottom rail. In this way the fixtures are permanently positioned as desired, although it is a simple matter to remove one of the fixtures if necessary and the fixtures are firmly fastened in place without the necessity of spot welding or some similar operation. The lift cords I2 are fastened in the fixtures IS in the manner shown in Fig. 4. A sleeve l9 fits within the arch I4 and a flange 20 thereon prevents the sleeve from being pulled through the arch H. A clip 2| is provided for grasping the end of the cord II. This clip is a sheet metal member provided with cord engaging prongs 22. The rounded portion 23 of the clip serves as a spring to separate halves 24 and 25 thereof to permit insertion of the cord. After the cord is inserted, the clip is brought together and is slid into the sleeve I9 as shown and the portion 23 of the clip which is larger than the opening in the sleeve l9 firmly holds the cord in place. This greatly simplifies attaching or detaching the cord and is of advantage in permitting easy removal of the slats if desired without the necessityfor untying and re-tying the cord or for cutting the cord and without calling for completely re-threading the lift cord through the blind.
If a long blind which is heavier is to be made, it is desirable to use a multiple system of lift cord. In that instance the cords I 12 are fastened centrally of the head member of the blind and pass down to the bottom rail, along the bottom rail to points adjacent the end, similar to the points shown for the location of the fixtures l3 in Fig. 4. The cord then passes up to the head part and over apulley and down. This system is well known in the art and I have not shown and described it in detail.
InFig.7Ishowafixtureforinsertion inmy bottom rail at the center thereof for use in connection with such a double lift. The fixture is held in position as shown in Fig. and provides passage for the two sections of lift cord 2. Arches I" are provided similar to the arch ll, although these arches are offset from one another so that the lift cords "2 are disposed substantially in a plane at right angles to the length 7 of the bottom rail, permitting them to be placed more closely together than would be possible using two fixtures such as I! at the center of the rod.
In Fig. 8 I show a fixture 26 for insertion at the end of my bottom rail 6. This fixture is a stamping consisting of two members 21 perpendicularly disposed on a base 28 apertured at 29 to receive a pin 30 which extends from the end of the rail to serve as means for fastening the rail when the blind is down.
The ladder tapes are fastened to my bottom rail in a new and improved manner. The ends of the front and rear portions 4 and 5 are each bent back on one another as shown at 3| and 32 in Fig. 3 and the folded back portions are held in position with staples 33. A clip 34 which is a stamping of sheet metal is provided. This clip has a recess 35 into which the folded portions of the ends of the front and rear portions 4 and 5 of the ladder tape are held. The unfolded portion of the ladder tape passes between the clip and the bottom rail 8 and the clip is clamped against the bottom rail so that the folded portions of the ladder tape serve as stops to prevent the ladder tape from becoming detached from the bottom rail.
Arms 36 formed to clip on the bottom rail 6 are provided. These arms are spaced from one another forming a space 31 through which the unfolded portion of the ladder tape passes. It will be appreciated that when the lift cord fixtures are positioned, the ladder tapes may be easily fastened in placeby means of the clip without the necessity for any spot welding or punching or other fastening means. Since no great weight is placed on the ladder tapes at this point, the clip serves as a most satisfactory fastening means.
It will be appreciated that my bottom rail can be made 'up in lengths and cut oflc' as desired and that the metal stampings serving as lift cord fixtures or the like may be inserted and simply, quickly and easily anchored in place, stock fixtures being used in all instances, which greatly simplifies the assembling and retailing of Venetian blinds.
