to invention relates to new and useful im-' movements in blinds.

"this application is flied as a continuation-inurt or my copending application, Serial No. lit,llll,'hled December 4,, 1936.

Une object of the invention is to provide an improved blind oi the slatted type which is adapted tor use with motor vehicle windows, and particulorlv with windows having curved outlines lt such as are usually found in motor vehicles or wrest design; the construction or the blind bc-V log such that an efilcient sunshade is provided without materially interfering with the lateral vision or the operator.

its important ohicct of the invention is to provide on improved blind or the slatted type which to so constructed that the operation oi the blind, that is, raising or lowering sold. blind or tilting the slots, thcrooi, mar be controlled from u. single ltd point and with one hand, whereby the operation is greatly facilitated.

ll particular ohiect oi! the invention is to provids on improved vehicle blind having rigid guide members upon which the slats are slldable, whererd hy said slots ore positively guided in the vertical movement and the tendency of the slats binding or hunging during their vertical movement is substontialiy eliminated; the guide rods also being orronged to secure the blind in position in the or window Home, whereby auxiliary iastenlng means for this purpose is eliminated and a simpler construction produced.

Another object or the invention is to provide an improved vehicle blind, of the character dous scribed, which may be readily applied and mounted within a motor vehicle window frame without the necessity of structural changes in said frame and without marring the finish or said frame.

A further object of the invention is to prom vlde an improved blind of the character described, wherein lengths of cord or a similar flexible element, are employed to connect the'slats together ior simultaneous operation and to hold the same in their proper spaced'relatlon; the w arrangement of said cord being such that most eiflclent operation is bad and manufacturing is not only simplified, but the cost thereoi is greatly reduced.

Still another object of the invention is to proso vide an improved motor vehicle blind, of the character described, having means for readily adjusting the slats to various tilted or inclined positions, wlth means for holding the same in such position.

or A construction designed to carry out the inventlon will he hereinafter described, together with other features or the invention.

In the drawings, the numeral l0 designates an automobile or other motor vehicle having window openings ll therein. In the usual window structure, a molding I2 is fastened in the window frame and is provided for covering the edges or the upholstery to give a more finished appearance to the inside of the window opening. The window glass which is movable vertically to close the window opening'ls disposed in a vertical plane outside of this molding. The blind structure, hereinafter described, is adapted to be mounted or secured to this inner molding l2.

The blind frame includes an elongate supporting bar or base member it which has its underside curved to fit snugly on the lower sill strip of the molding l2. This base member or bar 65 has a width substantially equal to the width of the molding, as is clearly shown in Figure 4. Since the molding has its surface curved downwardly toward the inside of the vehicle, the tendency for the bar I2 is to slide inwardly of said molding. To prevent such inward movement of the bar, a pair of angular clips l4 are secured to the bar. Each clip is angular in cross-section and has its upper leg overlying the top of the bar. The vertical leg of the clip I4 extends downwardly contiguous to the outer surface of the bar and has 'its lower end engaging the outer side of the molding. Manifestly, when the bar is in position on the molding, the clips prevent inward displacement of said bar.

An upper frame bar I5 is adapted to fit the curved portion of the top sill of th molding I2. This upper bar has a width substantially equal to the width of the lower bar and is also pro.-

vided with angular clips I6 which overlie the bottom and outer side of the bar I5. Manifestly,

the clips I6 prevent inward displacement of the bar For holding the frame bars I3 and I5 in position on the molding I2. a pair of vertical .rigid rods I! are adapted to extend between said bars. As is clearly shown in Figures 3 to 5, the rods are spaced from each other, being located nearer the vertical sides of the window openings I I. Each rod has its lower end threaded to an opening I4 provided in the clip I4 which is fastened to the base member or bar I3. The extreme lower end of the rod extends into an opening I3 which is formed in the member I3 below the opening I4 5 in the clip. The upper end of each rod I'I extends through an'opening I6 in the clip I6 and into an opening I5 formed in the upper frame bar I5. This upper end of the rod I1 is externally screw-threaded to receive a nut I8, which 40 nut is adapted to be screwed upwardly on the rod until it abuts the clip I6. With this 9.1- rangement, the lower ends of the rods I! are firmly fastened within the clips I4 on the base member I3. The upper ends of said rods are free 45 of direct connection with the upper frame bar I5 and when the nut I8 is screwed upwardly against the fram bar I5, the frame bars I5 and I3 are forced into tight frictional engagement with the molding I2. In order to remove the bars from 50 the frame, it is only necessary to unscrew the nut I8 so as to move it away from the bar I5. The upper bar I5 may then be lowered with relation to the rods I'l, whereby itmay be disengaged from the sill I2. Thus, it is not necessary 55 to employ screws or other auxiliary fastening means for mounting the frame bars on the molding I2. The bars are held in position by the frictional engagement with said molding, m The rods I! not only provide an efficient fastening means for holding the frame bars I3 and I5 in position within the window opening, but

also provide a. guide means on which a plurality 70 met prevents rattling and undue noise created by the slats striking the rods. The slats I9 are connected together by connecting cords and are arranged to operate in the usual manner of a.

Venetian blind. The particular threading of the 1s cords through and around the slats I8 is an important feature of the invention for it greatly simplifies the construction.

In connecting the slats by means of the cord, a cord A (Figure 5) has one end secured to the base member I3 adjacent one of the clips I4 and 6 this cord extends upwardly through an opening 22 formed in the lowermost slat I9. After passing through the opening 22, the cord overlies the top of the slat and is passed downwardly through an opening 23 which is provided in the slat and l which is located substantially midway between the central opening 20 through which the guide rods I'I extend and the outer edge of said slat. The cord A is then passed downwardly beneath the slat and inwardly toward the center thereof, after 15 which the cord passes upwardly through the opening 20 and is then brought over the top of the slat and back downwardly through the opening 23. After again passing through the opening 23 (Figure 4) the cord passes beneath the slat to the outer edge thereof and is then brought upwardly toward the slat next above; Upon reaching the next above slat, the cord extends past the outer edge thereof and is then directed inwardly over the top of said slat and downwardly through 25 the opening 23. After passing through the opening 23, the cord is passed inwardly beneath the slat, upwardly through the opening 20, then over the top of said slat and back downwardly through the opening 23, then beneath 30 the slat, after which it extends upwardly to the next above slat. The cord is thus fastened to each slat in order and by observing Figure 4, it will be seen that the cord describes substantially a figure eight through the

opening

23 and 20 of each slat. After being connected to the uppermost slat, the cord A is directed inwardly and passed upwardly through an opening 24 which is formed in the upper frame bar I5. The opening. 7 24 communicates with a longitudinal groove 25 provided in the bar I5, whereby the cord A extends into said groove. From the groove, the cord is passed through an opening 28 which has a ferrule 21 disposed therein, said opening being directed laterally through the side wall of the frame bar I5. After passing through the ferrule, the cord A extends downwardly and has its lower end secured to a ball 28. As is clearly shown in Figure 4, the opening 26 is disposed on the inner side of the frame bar I5 and, manifestly, the cord A, which is secured to the slats and which extends upwardly through the groove 25 in the frame bar, has its inner end located within the inside of the vehicle.

The cord A is a continuous link and is fastened to one side of the slat I9, such fastening occurring adjacent one of the guide rods I1. A sec-. and cord B, which is secured to the slats in the same manner, has one end secured in; the base member I! adjacent the cord A and is then exno tended upwardly and connected with the various slats on the side opposite that to which the cord A is fastened. Upon connecting with the uppermost slat, the cord B is passed upwardly through the opening 24 and extends through the groove to an opening 29 which has a ferrule 30 therein and which is located in the wall of the frame bar It adjacent the opening 28. After passing through the opening 29, the cord B extends downwardly on the inside of the slats and-is secured to an operating bah 3|.

From the foregoing, it will be seen that the cord A, which is secured to the ball 28, is connected to one side of all'of the slats adjacent one of the guide rods, while the cord B is secured to til the opposite side of said slats also adjacent said rod. By exerting a pull on the'ball 28, it will be seen that the cord A will be pulled upwardly through the opening 24 and outwardly through the opening it. When this occurs, a pull is exerted on the outer longitudinal edges of the slats, which edges are engaged by the cord A and thus an upward pull will cause a tilting of the slats. Similarly, adownward pull on the ball ill will cause the cord B to pull upwardly on the opposite longitudinal edges of the slats, whereby said slots are tilted in an opposite direction.

the cords h and H provide for a connection at one end portion of the slats and, for connecting the opposite end portion of the slats which is that portion contiguous to the other guide rod ii, sirnilar cords h and B are provided. The cord or is secured to the slats in exactly the same manner as the cord A and this cord extends upwardly through an opening N formed in the upper irame bar it adjacent to the other guide rod ill. The cord as extends through the longitudinal groove it in the bar and passes through the opening Ed and ferrule 21 alongside ol the cord it. The extremity of the cord A is also secured to the operating ball 28. Similarly, the cord h is iastened to the slats opposite the cord it and has its end extending through the opening it and then through the groove it in the bar iii, after which it passesthrough the opening and ferrule 30 alongside of the cord B. The ertremity oi the cord B is secured to the operat ins, ball 3i along with the cord B. With this arrangement, it will be obvious that when the ball lid is pulled downwardly, an upward pull is started onthe cords A and it whereby the longitudinal edges oi the slats which are engaged by the cords A and a are pulled upwardly, resulting in a tilting oi the slats. Of course, when the ball it is pulled downwardly and the slats are tilted, a. downward pull is exerted on the cords B and H due to their connection with i the slats, with the result that the hall 3| auto rnaticnlly rises.

When it is desired to tilt the slats in an opposite direction. a downward pull on-the ball M will cause the cords E and B to exert an upward pull on the longitudinal edges of the slats which are engaged by said cords B and B and thus a tilting oi the slats in the opposite direction may be accomplished. or properly manipulating the balls tit and it, it is possible to obtain a desired tilting or adjustment of the slats. Due to the particular fastening of the cords to the slats, said cords are more or less taut, with the result that the slats remainin any position to which they are adjusted.

The cords A and A, as well as the cords B and it, are utilized not only for controlling the tilting oi the slats, but are also employed for raising and lower-inn said slats between the frame bars I! and in Figure 5, the slats are in their raised position and are held so by the cords. As is clearly shown in this figure, a length of cord 32 has its entrcnrities secured to the balls 28 and Si whereby a loop is termed below said balls. This loop which connects the balls has the socket .rnenrrber 3t oi a snap fastener mounted thereon and said socket member is adapted to snap onto the usual button 34 of this type of fastener, which button is secured to the inner longitudinal edge of the base member IS. The length or the cords A, A',,B and B, as well as the length of the loop at, is such that when the slats I! are in their raised position, the socket 33 is directly opposite the button at of the fastener, whereby said socket may be engaged with said fastener. The socket i3 is slidable on the loop 32 so that when the fastener is engaged holding the slats in a raised position, the balls 28 and Bi may be moved, which moves the loop with relation to the member 33, said loop sliding through its connecting means. Thus, a tilting or adiusting oi the slats may be accomplished with the same being held in their raised position.

When it is desired to lower the slats, it is only necessary to disengage the socket member 33 from the button it and permit the slats to tail downwardly through their own weight. If desired, a second button 3t may be provided on the upper ire bar iii, whereby when the slats are in a lowered position, as shown in Figure 3, the socket di may be snapped onto the button it so as to lreep the mine out of the way.

When the slats are in a lowered position, they rest on the lower sill of the molding it and if desired a retaining strap tt' may be engaged thereovcr so as to rigidly hold the slats in engagernent with each other when the same are lowered. The strap would prevent undue rattling of the slats when in such lowered position.

It is pointed out that the slats iii are guided in their movement by the rigid guide rods H which are comparatively small in cross-section, whereby when the slats are in their lowered position, said rods do not materially interfere with the vision of the occupant oi the vehicle, and also whereby said rods do not detract from the appearance of the vehicle. Further, the rigid rods positively maintain the slats in position within the trams when said slats are raised, thereby preventing the wind or auction created by the motion oi? the vehicle irons displacing or interfering with the blind. so, the rod has a smooth surface, any tendency oi the slats to hang or bind on said rod is eliminated.

in Figures to it, the slats it are shown as resting directly on the lower sill oi the usual molding it, whereby when they are in a lowered position they extend slightly above the plane of said sill. If it is desired to hide the slats from view when observing the some from the outside of the vehicle, it would be possible to provide a recess 36 on the inside of the window opening as shown in Figure 7. in such event, the lower sill it of the molding it would belowered with relation to the window opening and, in such event, it will be obvious that when the slats are in a lowered position, the uppermost slat is below the bottom of the Window opening on the outside of the window glass oi the vehicle.

Although it is desirable to employ the rubber grommet or insert it to prevent undue rattling oi the slats it when in a raised position, such grommet may be eliminated and the opening through which the guide rods Ill extend made as shown in Figures 8 and 9. The opening 20' cylindrical and substantially equal to the outer diameter oi the rod whereby a substantially snug fit between the rod and opening is had. The upper and lower ends oi the opening are bevelled as shown at its, such bevels being on each side of the rod and extending transversely oi" the slat. With such arrangement, it will be obvious that a longitudinal tilting of the slat is impossible because the transverse width of the opening is substantially the same as the diameter of the rod. However, due to the bevelled portion 20a, it is possible to tilt the slat transversely,

whereby a proper adjustment of said slat may be obtained. When the slat is tilted transversely, the fulcrum of the slat occurs at the point 20b (Figure 9) which is that point midway between the bevel 200'. With this arrangement, undue rattling of the slats is prevented, while the tilting of said slats is permitted.

As has been pointed out, it is desirable that the cords which control the tilting of the slats are also employed for raising and lowering said slats, but this is not essential. In Figures 10 to 12, a modified form of the invention is disclosed, wherein a separate adjusting means for controlling the tilting of said slats is provided. Referring to Figure 10, it will be seen that this form comprises an upper frame bar and a lower frame bar M, which have a pair oi rigid guide rods d2 extending therebetween. These rods are fastened in the flame-bars and ii in any suitable manner and said bars are secured to the molding E2 of the vehicle by means of elongate screws which pass through the cars and through the molding into the frameoi the vehicle. In this form), the frictional engagement of the frame bars with the molding is not had.

A plurality of elongate fiat slats 83 are slidable vertically on. the guide rods 52, each slaq' having a pair of openings 44 through which the rods extend. The slats are connected together by connecting cords 45. Starting at its upper end 45', each cord is.directed from the outer edge of the uppermost slat transversely beneath said slat to the opening 44 in said slat. The cord extends upwardly through the opening and is then directed outwardly to the outer edge of the slat, after which it is extended downwardly to the next slat. At the point of intersection of the cord with its upper end 45', a knot 45 is tied. The cord is then extended downwardly to the outer edge of the slat next below and is directed inwardly beneath said slat to the opening 44, then upwardly through said opening and outwardly over the top of said slat, being knotted at 46', which knot is located contiguous to the outer edge of the slat. From said knot, the cord extends downwardly to the next below slat and is similarly secured thereto and to each succeeding slat as shown in Figure 10. Cords similarly secured to the slats are provided on each edge of the slats adjacent each vertical rod 42. The lowermost slat is connected to the lower bar 4| by short cords 45a secured to the mid-portion of the slat and the bar near the guide rods 42 (Figure 10).

For lowering and rasing the slats, a pair of lifting

cords

41 and 48 are provided. Each cord has one end secured to the mid-portion of the upper slat near one of the guide rods 42 and extends upwardly therefrom to an opening 49 provided in the uppr frame bar 40 and projects into a longitudinal recess 50 provided in the upper portion of said bar. After passing through the groove, the cord passes through an opening 5| formed on the inner side of the bar and communicating with the groove 50. Said cords pass through an eyelet 52 and then are directed downwardly and connected together at their lower ends. A suitable socket 33 of a. frictional fastener is attached to the lower ends of the

cords

41 and 48 and this socket is adapted to engage a button 34a fastened to the lower frame bar 4!. Manii'estly, by raising and lowering the

cords

41 and 44, the slats may be raised and lowered. The upward movement of the slats is limited by the short cords 45a. which connect the lowermost slats with the base member 4|.

For varying the lateral inclination of the slats in this form, a recess 53 is provided in the lower bar 4| near one of the vertical guide rods 42 (Figure 11) and a semi-circular gear sector 54, having diametrically opposed arms 55 forming extensions of its upper straight edge, is mounted on a transverse shaft 56 within said recess. This gear sector meshes with a worm gear 51 which is mounted on a shaft 58 which extends transversely within the bar 4i and which also ex tends transversely through the recess E53. One end of the shaft 58 projects from. the inner side of the bar and has a knurled operating knob 53 secured thereto, whereby the shaft may be manually rotated to rotate the worm; and thereby swing the gear sector 5%. Tie cords $6 extending through openings provided therefor in the lowermost slat near its outer edges, are secured at their lower ends to the ends of the radial arms 55 of the gear sector 56. These tie cords are taut when the blind is in its raised position, and it will be seen that movement of the gear sector will vary the inclination of the lower slat due to its connection thereto through the tie cords. Since all of the slats are connected by the taut connecting cords 45, it will be obvious that any inclination of the lowermost slat will be imparted by said cord to all the slats. The frictional engagement of the worm gear shaft 58 serves to prevent accidental movement of the gear sector and thereby serves to maintain the slats in any desired adjusted position.

From the foregoing, it will be seen that the improved blind shown in the' various forms, may be readily raised or lowered and set at any desired inclined position with only one hand, whereby the operator of a vehicle may readily manipulate the blind without stopping the vehicle or in any other way being interfered with in such operation of the vehicle. Due to the fact that the slats of the blind are spaced from each other when in a raised position, it will be seen that the lateral vision of persons within the vehicle is not materially interfered with, yet the inclination of the slats provides an effective sunshade.

It is further noted that since the guide rods 42 are spaced inwardly from the vertical sides of the window opening II, the slats may be made of varying lengths so as to follow the curvature of the window when in a raised position, whereby the slats extend completely across the window opening when raised, and thereby shade the interior of the vehicle.

The blind may be easily installed in the win dow frame, the form disclosed in Figures 1 to 6 being readily applicable or removable without the use of an auxiliary fastenin means. In the form shown in Figures 10 to 12, the usual openings provided in the molding may receive elongate screws, whereby the construction of the vehicle need not be altered to accommodate the blind. It is to be understood that the slats of the blind may be made of any suitable material and any suitable manner of connecting the slats may be-employed. It is preferable that the slats be made comparatively thin to reduce bulkiness in the lowered position because of the limited space within a vehicle window. With the arrangement described, it is possible to construct the slats of very thin material because it is not necessary that the slats be sumciently thick to iii ill

Elli

it'll till receive tacks, screws or other fastening means in their edges. v

The foregoing description of the invention is explanatory thereof and various changes in the size, shape and materials, as well as in the details of the illustrated construction may be made, within the scope of the appended claims, without departing from the spirit of the invention.
