VENETIAN BLINDS Filed Feb. 11, 1931 Patented Apr. 25, 1933 UNITED STATES PATENT? OFFICE IBM) J. BURNS, F SAGINAW, MICHIGAN, .ASSIGNOR TO COLUMBIA MILLS, INCORPO- RATED, OF SAGINAW, MICHIGAN, A CORPORATION OF NEW YORK VENETIAN BLIND Application filed February 11, 1931. Serial No. 514,952.

his invention relates to venetian blinds, and more particularly to the type of blind having a plurality of slats, means for supporting the slats in spaced apart positions, together with the usual means for operation of the parts, and it is the prime object of the invention to provide means for, maintaining the slats of the blind in a predetermined position with relation to the window casing, preventing displacement due to wind or any other reason, and still provide sufiicient play or endwise movement so that the operation of.the blind is free and easy, and also insuring more certain the raising and lowering.

Another object of the invention is to provide neat, sturdy and inexpensive means for.

permitting a limited endwise movement of the blind in the opening, andfor preventing the blind swinging back and forth like a curtain, striking and marring the window frame, with noise and rattle resulting therefrom. A further object is to provide detachable means for locking the slats to'the guides, which can'be detached or attached regardless of the position of the slats, and which can be readily manipulated so that the entire blind structure can be dismounted when the slats are detached.

the specification progresses, reference being had to the accompanying drawing in which I have shown tlm preferred embodiment of my invention, and in which like numerals indicate like parts throughout the several views thereof.

In the drawing. Fig. 1 is a fragmentary front elevation of a window equipped with a venetian blind embodying the principles of my invention. Fig. 2 is an enlarged front elevation of one of'the guides ,with a glider in position thereon. r Fig. 3 is an enlarged part sectional view taken on the line 3-3 of Fig. 1 and showing the connection of the blind to the guide rail. Fig. 4.is a plan view showing a modified style of glider bracket. 0 Fig. 5 is an enlarged part sectional view The above and other objects will appear as and 18 respectively, and side wings 19 which showing an offset bracket, parts being broken away to show the key slot in the slat.

F 1g. 6 is an enlarged detail view of an offset glider bracket illustrating the locking head in locked position, the dotted lines illustrating its removal.

Fig. 7 is. an isometric view showing a slightly modified construction.

Referring now to the drawing, the window frame or casing is indicated by the numeral 5 and the venetian blind 6 is hung therein and includes a lurality of spaced apart slats 7 secured toget er by means of flexible strips 8, and those slats can be tilted to exclude light and air, the tiltingmechanism not being shown as it forms no part of the present invention.

Vertically disposed sheet metal guide rails-9 are secured to the sides of the window frame by means of screws (not shown) and are formed as clearly shown in Fig. 2 of the drawing, wings 10 extending laterally from the main body, and a glider member 11 is v 'slidably mounted thereon, said glider comprising a flat preferably stamped body member formed with inwardly turned leg sections 12. which engage and slide on the guide wings 10, outwardlv 'rolled sections 13 are provided on the glider bracket. and a lug 14 is provided as shown. said l-ug being preferablv formed integral with the glider and acting as a stop in a manner to be presently described. A resilient clip 15 is also provided intermediate the length of thebody and is adapted to be actuated to permit the insertion orremoval of the locking member 16, said locking member being formed as clearly shown in Fig. 6. having end walls 17 when in position, interlock with the turned portions 13 of the glider, and itwill be obvious that when said glider is engaged, that the stop '14 limits the outward movement thereof, the resilient member 15 preventing its disengagement until it is sprung down to permit thelocking member to be removed.

Acentrally disposed opening is provided in the face of the locking member and is adapted to receive the outer end of a pin member 20, the end being headed for securing said pin in position.

The in member 20 is formed as clearly shown 1n Fi 5 of the drawing, the inner end being substantially flat and rectangular in shape, and is shouldered as at 21 and for a purpose to be presently described.

A metal clip 22 is secured to the end of the slat as shown, and an 0 ening 23 is provided in the end wall thereo and through which the shank of the pin extends, the slat being recessed as at 24 to permitof a limited lon-. gitudinal movement of the pin member there- 'in. Inwardly turned ears 25 are punched in the clip as shown,'and when the clip is placed in position these ears pierce the slat, the ends coming in" contact'with the opposite leg of the clip and are accordingly clinched to secure it firmly in position.

It will of course be obvious that the location of the guide rails is dependent on the design of the window frame and the space available for attachment thereofyand naturally various shapes of gliders are necessary to meet all conditlons, and in Figs. 5 and-6 of the drawing I have shown a glider having a laterally projecting leg 26, and this is for use where it is impossible to place the guides in direct alignment with the blind. Fig. 4 of the drawing shows another design of bracket, the locking feature however being exactly the same.- In Fig. 7 I have shown a slight modification; in this construction, the resilient member comprises an individual spring 27 which is secured in place by formmg the glider with ears 28, which are then ressed over the lower end of the spring, this .is however, immaterial, as the principle is exactly the same.

From the foregoing description it will be obvious that I have perfected a very simple, substantial, practical and neat looking attachment, which is connectible to and disconnectible from the glider members in any position of the slats.

What I claim is: l

1. In a venetian blind having a plurality of movable slats, a guide rail secured to a window casing, a glider slidably mounted thereon, and disconnectible securing means between said glider and movable slats, and disconnectible in any position of saidslats.

2. In a venetian blind having a plurality of movable slats, a guide rail secured to a window casing, a glider slidably mounted thereon, a pin loosely mounted in the end of the blind slat, a locking member revolubly mounted thereon, said member being disconnectible from said glider in any position of said slat, and resilient means for locking said member on the glider. I

3. In a venetian blind having a plurality of movable slats, a guide rail secured to a window casing, a movable glider member associated therewith, a pin mounted in the end of the blind slat and having limited endwise movement'therein, and a locking member revolubly mounted on the opposite end of the pin and separably engaging the said glider.

4. In a venetian blind having a plural' ity of movable slats, a guide rail secured to a window casing, a movable glider member associated therewith, removable securing means between said glider and one of said slats, said means including a revoluble locking member having interlocking engagement with the glider, and disconnectible in any position of said slats.

5. In a venetian blind having a plurality of movable slats, a guide rail secured to a casing, a movable glider associated therewith, a pin mounted for endwise movement in said slat and provided with a revoluble head having interlocking detachable engagement with said glider, and resilient means on said glider for holding'said head in locked position.

6. In a venetian blind having a plurality of movable slats, a guide rail secured to a casing, a movable glider associated therewith, a pin mounted in the end of a blind slat, a looking member mounted on the projecting end of the pin and having interlocking engagement with said glider, and resilient means on the glider for holding said member in locked position.

7. In a venetian blind having a plurality of movable slats, a guide rail, glider members slidably associated therewith, a pin having its one end loosely mounted in said blind slat, a locking member revolubly mounted on the opposite end and engageable with said glider, and resilient means on the glider for holding said member in locked position.

8. In a venetian blind having a plurality of movable slats, a guide rail, a movable ghder associated therewith, a pin mounted in the slat and projecting laterally therefrom, and a locking head revolubly mounted on the pm and adapted to detachably engage said glider member, said head being connectible to or detachable from the glider in any position of the slats.

9. In a venetian blind having a plurality of movable slats, a guide rail, movable glider member, said head being connectible to or on the blind slat and projecting from the end thereof, a locking head revolubly mounted thereon and engageable with the glider member, a sto on sa1d glider, and resilient means spaced om said stop for holding said head in locked position.-

In testimony whereof I hereunto afiix my signature.
