GERTZON VENETIAN BLIND CONTROL 2 SHEETS SHEET 2 Filed Nov. 1, 1948 Z/f/I/l/ (-Ili [1 [/11 INVENTE'ESJ Patented Apr. 29, 1952 UNITED STATES PATENT OFF ICE 2,594,637 'VENETIAN BLIND CONTROL Thora Magdalena Gertzon, New York, N. Y.
Application November 1, 1948, Serial No.- 57533 1 5 Claims. 1 Thislnvention relates in general to a Venetian blind control and in particular to a control operated by a single cord. As far as 'I am aware, all Venetian blinds on the .market are operated with four cords. Two lifting and lowering the blind and :two for tilting the blades.
The principal object of my invention, is to provide a simple means of operating Venetian blinds.
Another object of my invention is to provide an improved type .lock for locking the blind .in any position without damage to the .cord.
A still further' objec't of my invention is to provide a system of rollers located in the support box at the .top. Said rollers are to receive the two cords for lifting the blind, thus only one cord emerges from the support box. Said single cord is used for operating the blind.
A further object of my invention is to provide simple means of lifting, lowering and operating the blades with a single cord.
Further objects and advantages of my invention willtappear from the following description in conjunction with attached .drawing in which:
Fig. '1 is an elevation of the operating mechanism and the principal parts of my invention applied to a Venetian blind.
Fig.2 is a transverse vertical elevation taken upon the line w-a, Fig. 1.
Fig. 3 is a diagram showing the arrangement of placing the two support cords into the support box.
Although my invention may be applied to any cover for doors and windows, regulating door and manhole cover openings, I will for the purpose of: explanation describe the invention in connection with a Venetian blind of which the box I is the support of the Venetian blind, generally made of wood. II is a metal box embodying the principal parts of my invention. On Fig. 1, II is shown with the cover l2 removed. The wheels I3 are supported by their shafts going through the walls of box II and cover [2. The wheel I4 is supported by its shaft going through the carriage [5. The spring [6 in conjunction with the wheel I4 and the carriage I locks the cord I! when it is so desired. A wedge-like member I8 is free to slide inside the carriage [5, operating plug I9 which controls I5 through the slot which is part of I5. 2| and 22 are levers actuating a corrugated wheel 23 for tilting the blades through the blade support 24. 25 and 26 are pins riveted to 2| and 22 respectively. 21 is a spring washer holding tilt rail 24 at a desired angle. 28 is a fork supporting 2|, .22 and '23. 2.9 is a Venetian blind blade of which only one is shown; 30 is a canvas strip supporting the blades. 3] are screws attaching box II to ill. 32 are screws attaching cover I2 to box I I. 33 arecords lifting the blades 29 when the cord 11 :is pulled down. 3'4 are wheels receiving :cords .33. 3.5 are two double wheels receiving the two cords 33 when I] is pulled down. (36 are guides preventing the cords 33 from twisting.
The operation of my invention is as follows-:
On Fig. l cord ['1 is held in-a locked position through the force applied byspring l6. Pushing the cord H toward the right will move carriage I5 and the slide I8 to the right, releasing plug I9 into slot '20, thus "keeping the wheel l4 also at the right, leaving cord 1-! free tomove either downwards by the force of the hand, lifting the Venetian blind up; or let 'I 'I go upwards by the gravity force of the blind, thus the Venetian blind will go down. To stop it at any desired position, pull the cord 'I toward the left, thus 18 will push up plug I9 and the spring is will move the carriage l5 and the 'wheel M into the locked position. Pushing the cord ll forward against the pin 25 will move the lever 2| against the wheel 2; turning 23 and 24, thus tilting the blades 29 clockwise facing line 11-11.
