Application October 2, 1950, Serial No. 138,030;

- 1 f4 Claims. (01. 1e02cs) This invention i concerned with a window blind guide and is'useful in connection with roller type Windowblinds or shades, it being a general object of the invention to provide a construction that is simple and practical for the purpose of 5 the roller, and they are'spaced apart so that the facilitating the proper guiding of a web or blind blind operates between them. Each guide inonto its supporting roll. v volves a shoe with a guiding face, preferably con- Windows such as occur in wall of homes or vex in form, which face is engaged-by anedge of buildings are commonly equipped with shades or the blind. Lips project from the sides of the shoe blinds, and the usual device of this character is of and are vertically disposed and spaced apart so the roller type and is mounted on or carried by the case of the window at the top or upper portion thereof. The usual blind involves a roller supported by brackets and the blind proper is in the nature of a flexible sheet or web, usually a fabric suitably treated or coated. The lower or depending edge of the usual blind is reinforced with a stiffening member and a cord or pull depends from the lower end of the web to facilitate operation thereof. Considerable care and skill is required to operate a web of the character mentioned accurately with reference to the roll, and whencare and skill are not exercised, as is usually the case, the web winds onto the roll so as to cause an edge of the web to rub at an end of the roll and consequently become damaged or chafed.

In practice the usual blind of the character referred to after being used but a short time has both edges more or less damaged, and thus rendered unsightly. r 7

It is a general object of this invention to provide a guide or guiding construction which serves to so guide the web or blind proper onto its supporting roll as to eliminate the usual damaging of the web, even though it is operated casually and without the exercise of great skill or care.

Another object of this invention is to provide a combination of parts wherein a, blind is related .to guides which occur on a common frame or case and which are spaced from the supporting roll of the blind so that the blind is accurately guided with reference to the roll whenever it is operated.

Another object of this invention is to provide a simple unitary blind guide applicable to a window frame or case at a suitabl point below a blind carried by that case and which serves to guide an edge of the blind and confine it, to the end that the blind can be operated repeatedly without damage or injury.

In the structure provided by the invention a window frame has vertical parts or sides and a header between the upper ends of the sides. A blind of the roller type is mounted on the upper portion of the frame, for instance, adjacent the header. The roller of the blind is mounted by means of suitable brackets and the web or blind proper is carried on the roller and depends therefrom to extend between the sides'of the case.:' A pair of guides isprovided on the'case, preferably the sides of the case, a suitable distance below that an edge portion of theblind is received and held between themfmaintainin'g the edgeo'f the blind in proper relation to the guide'shoe, A mounting flange or base plate is provided on or in connection with the shoe'andis applicable to the window case as by means of suitablefasteners or serewsf The various objectsand features of my invention will be fully understood from the following detailed description of -typical preferred forms and applications of :the invention, throughout which description reference is made to the"accompanying' drawings, in which: v

Fig. 1 is a view showing a wall'having' a window therein and showing a blind'on thewindow case and blind guides related to th blind to maintain the web or blind portion thereof properly related to the roller thereof. Figs-2 is an enlarged broken detailed sectional View taken in the direction indicated by line 2-2 on Fig.1. Fig. 3' is a view taken as indicated by line'3-3on Fig; 2;' Fig. 4 is a view taken as indicated by line 44 onFig. 3. Figs. 5, 6 and 7 are views illustrating a'somewhat differentform of the invention, wherein the blind is mounted within the case of the window' rather than on the exterior of it. Fig. 5 illustrates one corner of the case, showing the'mounting of the blind and the :reiationship of the guide thereto.

Fig. 6 is an enlarged plan view taken as' indicated by line 66 on Fig. 5, andFig. 7 is an enlarged side elevation of the guide shown in Figs. 5 and 6. In the drawings I have illustrated a Wall W with a window'opening therein providedwith the usual case' A. A roller type shade or blind "Bis carried by the case A and guides Care carried by the case and are cooperatively related with the web or iblind 'p'r'oper of element B. The window case A beingof typical or conventional construction has a lower element or sill I0, vertical elements or sides H and a transverse top or header l2 between the upper-ends of-=the sides [I ii Referring to the form of theinvention; illustrated in Figs. 1 to '4, inclusive, the bl-ind'B is mounted on the exterior of" the case A and is shown as involving a roll 20 carriedfby suitable mounting brackets 2| applied 'to' the exterior of as to extend completely across the window opening so that its edges the case.

The present invention provides a pair of guides, one on each side ll of the case, and the guides are like opposed elements spaced 2. short distance, for instance a few inches, below the roll 20, and spaced apart a distance about equal to the width of the blind 22.

Each guide C preferably involves a shoe 30 opposing an edge 26 of the blind 22 and having a guiding face 3! that extends in the general direction of the guided edge 26. The face 3| is preferably convex in form and it 'may be pitched so that its upper end is close to or in guiding contact with the edge 26, while its lower end isspaced somewhat away'from the edge 26.

Ears 33 project from the vertical edges of the shoe 30 and extend toward the blind 22 to overlap the edge portions thereof. The ears 33 are spaced apart, forming a channel in which the edge portion of the blind operates with substantial clearance and in the preferred form of the 26 overlap the sides ll of invention the inner or opposed sides 35 of the ears are convex in form and thus effectively guide the edge portion of the blind, in the event .that the blind is operated when deflected from a true vertical position. A mounting flange or base 38 carries or projects from the shoe 30. In the case illustrated the flange 38 is disposed relative to the shoe 30 so that it bears against the face of side ll of the case A while holding the shoe 30 properly related to the edge of the blind 22, as clearly shown in Figs. 2 and 3 of the drawings. In practice any suitable means may be employed to secure the flange 38 to the case. In the drawings I have shown openings 40 in the flange 38 carrying mounting screws 4|.

In accordance with the preferred form of the invention each guide C as hereinabove described is a single unitary element, for instance, it may be a casting, and it is of such form that it can be advantageously manufactured in quantities and'at little cost. Furthermore, it is to be observed that-the guide or unit that I have provided is simple in action and is such that it can be easily and quickly mounted so it is related to a blind, as shown throughout the drawings. I

In the form of the invention shown in Figs. 5, 6 and 7 the blind B instead of being mounted on'the exterior of the case A is mounted within the case at the upper end thereof to be adjacent to header l2. In this case guides C' provided by the present invention, instead of being mounted on the exterior of the sides H, as shown in Figs. 1 to 4, inclusive, are mounted-at the interior of the case. In this situation each guide C may be advantageously formed with two mounting flanges 38', one projecting upwardly and the other downwardly, and each of these flanges may have a screw hole, as shown in Fig. '7 of the drawings.

Inother respects,'that is, as to the formation of the shoe and ears, this form of. guide may be the same as that first described.

In installing the guides c of the present invention a short distance, that is, a matter of a few inches, below the roller 20, they are inconspicuous and are so located that they do not in any way inconvenience a user. The guides being located as shown in the drawings serve to effectively guide the blind onto the roller and the defiections of the blind incidental to usual operation are corrected trally onto the roller. With the guides of the present invention, a usual blind can be operated without great care or skill over a long period of time without the edges of the blind becoming worn or chafed, as is usually the case.

Havingdescribed only typical preferred forms and applications of my invention, I do not wish to be limited or restricted to the specific details herein set forth, but wish to reserve to myself any variations or modifications that may appear to those skilled in'the art and fall within the scope of the following claims.
