June 4, 1940. E. M. TRAMMELL I HEADRAIL AS SEMBLY FOR VENETIAN BLINDS Fil ed Jan. '21. 1959 INVENTOR EARL M. TRAMMELL A TORNE Patented June 4, 1940 UNITED STATES PATENT orrica 2,203,372 HEADRAIL ASSEMBLY FOR VENETIAN BLINDS Earl M. Trammell, St. Louis, Mo., assignor to Huttig Sash & Door 00., St. Louis, Mo., a corporation of Delaware '10 Claims.

This invention relates to improvements in headrail assemblies for Venetian blinds, and more particularly to an improved construction of headrail and valance elements as well as improved bracket members for endwise supporting the headrail and valance in assembly, and therethrough, for supporting the operative elements of the blind structure.

According to the usual prevailing practice in the manufacture and erection of Venetian blinds, the operative elements and mechanism of the blind assembly, including tilting and lifting members, together with slats, tapes, etc., are carried in suspended relation from a single upper mounting rail commonly designated as a headrail. The headrail is supported in the window opening usually by end brackets of some form, and according to length of the blind and width of window opening, sometimes one or more intermediate supports have heretofore been required. A valance board when utilized, had heretofore been employed for the primary purpose of providing a facing or closure for the upper portion of the blind assembly, so as to conceal the tilting mechanism and certain of the lifting elements associated with the blind. As far as is known however, the valance, or valance board as it is sometimes designated, has heretofore formed no particularly useful structural or functional pur-' stricted to the use of providing merely an ornamental effect or closure for the purpose noted.

It is a major purpose of the present invention so to combine the headrail and valance in assembly as to utilize the valance as a part of the blind supporting structure cooperating with the headrail; more specifically and preferably, to employ the valance as a strut or trussextendin transversely of the window opening, but longitudinally of the headrail. The present invention in its broader aspects comprehends a general improvement in the head portions of the Venetian blind assembly of the type referred to.

A further general object of the invention may be stated as attained in a novel combination and. arrangement of headrail, valance and end brackets so assembled that the valance and headrail are interfitted, and the end brackets serve to surround the end portions of the valance and headrail in a manner better to enclose the operating portions of the assembly than in heretofore existing blind structures.

Yet another object of the invention is attained in means provided by improved construction of pose in the headrail assembly but has been rethat the valance and headrail, together with the blind elements supported thereby, may be quickly and easily demounted for cleaning or service, and quickly replaced to operative position without requiring any tools or special equipment, and 5 so that the demounting and replacement require only a minimum of time.

A still further object of the invention is atb tained in an improved construction of brackets for supporting a headrail, or a headrail and 10 valance assembly, the improvements in bracket construction being applicable to many types of Venetian blinds, and the elements of improved bracket design being in furtherance of certain of the objects heretofore stated. I 15 Yet another object is attained in an improved mounting means for the valance such that it may be readily and instantly removed and replaced without requiring any displacement of the headrail and appurtenant parts. 20'

The foregoing and numerous other objects will be apparent from the following detailed descrip-. tion of a preferred embodiment of the invention, considered in connection with the accompanying drawing, in which:

Fig. 1 is a front elevation of a Venetian blind assembly to which the improvements of the present invention are applied; Fig. 2is a fragmentary sectional elevation in a horizontal plane through the assembly of Fig. 1, particularly as taken along line 2-2 thereof; Fig. 3 is an enlarged front elevation of one end of the headrail, valance board assembly, and one of the brackets, as shown by Fig. 1; Fig. 4 is a vertical sectional elevation as viewed along line 4-4 of Fig. 3, and Fig. 5 is an elevation in perspective of one of the preferred forms of the brackets, showing the bracket as it would appear when utilized at'the right hand end of the headrail assembly.

Referring now'by characters of reference to the drawing, the preferred arrangement com-. prises the headrail l0 horizontally disposed to extend across the window opening, as indicated by Fig. 1, and to constitutea support for a tilt rail II, with which is associated ladder tapes I2 and tiltingmechanism generally indicated at IS; the tilt rail being mounted for example, by a flange l4 and a tilt rail bracket ii, the brackets l4 and i5 being secured, for example by screws extended upwardly into the headrail so that the blind assembly is mounted in depending relation thereto. Other modes ofmounting will suggest themselves to those skilied in the art, it being understood that the specific arrangement by I the end brackets for the headrail assembly, such which the operative elements of the blind are secured to the headrail, constitutes of itself, no part of the present invention.

The headrail I0 is provided with a forwardly projecting ornamental bead or beading 20, which portion is, for reasons of appearance and strength, projected forwardly of the valance or valance board, to be described. The forwardly projecting portionlfl serves not merely an ornamental purpose, being sometimes referred to as an architectural return, but serves, as will later appear, a distinctly structural function in establishing the relation between the headrail and valance. In the arrangement illustrated, the ornamental bead portion 20 is provided with a plurality of grooves or flutes 2|, being longitudinal recesses in the forward face of this portion of the rail.

In accordance with prevailing practice in connection with certain types of Venetian blinds, the upper surface of the headrail is provided with a longitudinal recess or groove 22 which serves as a channel for the horizontal passes of the lift ropes or wires (not shown). In the preferred embodiment illustrated, the under surface of the headrail l0 near its forward margin, and particularly just below the head portion, is provided with a longitudinal groove 23, which is preferably of a width substantially the same as the thickness of the valance which is indicated generally at 24. The innermost upper edge of the valance 24 is preferably chamfered or bevelled, along its entire length, as indicated at 25. As will clearly appear from Fig. 4, the removal of this portion of the wood or other material of the valance, facilitates insertion of the valance into groove 23 of the headrail in a manner clearly appearing from Fig. 4.

It is a preference that the headrail and elements supported thereby, be first assembled, then the-headrail inserted into the brackets, hereinafter described, which brings the rail l0 into horizontal position transversely of the window I opening. With the valance 24 inserted with its upper margin innermost, so as to present the bevelled portion 25 to the rail, the valance is applied by upward movement so as to bring its upper margin fully into the recess 23, following which the valance is brought to vertical position as groove 23 constituting a reentrant portion of the lower face of the headrail, the relation of the elements thus being an edge-to-face association ofthe parts whereby the headrail and valance when assembled, constitute the structural equivalent of a single, angle-shaped support.

Because of the manner of thus utilizing-the valance in aid of support of the'headrail, many of the, intermediate supporting brackets such as heretofore used on even' moderate lengths of blinds, may now be dispensed with, thus effecting a considerable economy not only for hardware and parts, but for installation time. It is further to be noted that the assembly of the headrail and, valance is accomplished without using screws, nails or like fastening means, all as .will' more clearly appear in connection with the description of the supporting brackets.

Turning now to the brackets per se, these. are

preferably formed in pairs such that one thereof is utilized at the right hand end of the headrail assembly, and the other at the left hand end thereof. Rig. 5 as well as Figs. 2, 3, and' 4 show a right hand bracket, but-the modifications thereof to constitute a left hand bracket will appear obvious to those skilled in the art. The preferred type of bracket is of the general form of an openside receptacle or box-like structure, having its open side presented toward the headrail and valance, and hence toward the window opening. One side is, however, prefera'bly substantially closed as by a side plate 30, characterized by right angle flanges 3| at the top of the bracket and 32 along its rear margin, and a partial front flange 33 extended inwardly of the front edge of the side wall 30. To permit the introduction of mounting screws or the like in substantially any conceivable condition of installation, the wall 30 is provided with a pair of screw openings, one of which is shown at 34. The back flange 32 is provided with a pair of openings 35, and the top flange 3| with a pair of openings 36. Generally, these pairs of openings will be selectively utilized, according to whether the bracket is to be mounted on the top rail, jamb, or on the rear facing or finish elements of the window.

The primary support for the adjacent end of the headrail is provided for by a horizontal headrail shelf 40 which preferably extends from the forward margin of plate 30 rearwardly a suitable distance, but a space remaining betwen the rear 'end of the shelf 40 and the rear flange 32 of the bracket. This permits access of a screw driver or thelike from within the bracket to a zone in line with the rearmost opening 36 in flange 3|. To provide for similar access to a screw in the forward opening 36, shelf 40 is apertured as at 4|. To aid in positioning the headrail in a fore-andaft direction with respect to the window, or transversely of the bracket structure and shelf 40, there is provided an instruck inverted tongue 42, the manner of usage of which is hereinafter referred to.

Referring to the forward flange 33 of the bracket, this is preferably formed of substantially L-shape in frontal aspect, and like flanges 3| and 32, is formed of an inturned marginal portion of the plate 30 so that but a single piece of metal is utilized for the elements 30, 3|, 32 and 33, it being preferred, for reasons of economy, to form the shelf 40 of a separate piece of metal bent up to a right angle, and including besides the shelf proper, a supporting portion 43 secured as by rivets or the like 44, to the side wall 30.

The L-shape flange 33 is of such form that at its lowermost margin is provided a forwardly ex- I tending foot, or substantially horizontal shelf 45 f constituting a seat .for the adjacent end of the valance in'much the same manner that the shelf 40 serves as aseat for the adjacent end of the headrail. Shelf 45 may, if desired, be turned upwardly to provide a lip 46 serving as an end stop for the valance, and just above the shelf is a placement of the valance beyond the vertical. It

will be noted that the forward edge of the stop 50 lies in the same vertical plane as the innermost vertical surface of the groove 23, so that. these parts cooperate in assuring a vertical placement of the valance 24, yet limiting its inward movement beyond that desired.

The flange 33 ;is provided with a notch or slot 5| near its upper portion and with a corresponding 76 tending portion 60 serves to abut but relatively inverted notch 52 entering its lower margin justadjacent the line of origin of the flange. The notches and 52 serve, in a manner appearing from Fig. 5, to permit entrance therein of portions of a displaceable holding ele-' ment or closure generally indicated at 53. Although the member 53 may be displaceably associated with the bracket in different ways, it is preferred that it include a rearwardly extending arm or leg portion 54 apertured as at 55 to receive a pivot pin or the like 56, which may conveniently consist of a rivet extending through a punched aperture in the lower forward. marginal portion of the side wall 30; it is about this pivot element as an axis, that the closure or holding member- 53 is swingably disposed.

It has ben found advisable and desirable in the case of a pivotal mounting of member 53, to extend the leg or arm portion 54 somewhat inwardly beyond the pivot member 56. This inwardly exthe inner surface of the flange 33, when the closure 53 is lowered to a point somewhat beyond horizontal position. This arrangement offers an advantage in assuring that the member 53 does not casually fall below a predetermined position in a manner to interfere with free introduction of the headrail and anclosure 53 is provided with purtenant parts, into the brackets. f The opposite end of the pivoted closure 53 is provided with a latch arm 6|, which in closed position enters the notch 51. The cooperating latch element of the preferred embodiment is constituted in part by an instruck embossed portion or boss 62 in the upper forward edge of the plate 30. .It is noted that the latch arm SI of the an aperture 63 of such a diameter that when the closure 53 is in its normal vertical position, the opening 63 receives the boss and tends to maintain, or latch the pivoted closure in its normal or operative position.

According to preference in the assembly shown by the drawing, the closure structure 53 is rounded in form, and is provided with a deepened, recessed, or cup portion generally identified with the zone 64, this recessed upper part of the closure 53 serving, when in closed position, to accommodate the ornamental bead'portion 20 of the assembly. It also serves, due to the shouldered con-' formity 65 (Figs. 4 and 5), to constitute a rest or seat for the forwardly projecting and overhanging ther to position the headrail and closure 53 relative to each'other,-the closure member is provided upwardly and somewhat forwardly of the seat 65, with indent portions 65, the particular conformity of which is preferably dictated bythe depth and arrangement of the recesses 2| along the bead portion preference that the portion 65 shall interfit, at least partially, the grooves 2|.

The manner of use of the brackets is thought to have been fully apparent from the foregoing description of parts, but it may be noted that the brackets are installed in a manner suggested by the location of supporting or holding screws 59 for example, and at such a level that the heada rail lflbridges the oppositely presented shelves 450i thepaired brackets. As the headrail l0 together with appurtenances, is disnosedon'the brackets, it is pushed inwardly orrearwardly as far as possible with the result that the tongues 42 snugly engage the rear edge faces of the headrail, and coact with the closures 53- to prevent rangement such that since .rail are substantially completely embraced, they any serious deflection of portion of the woodwork. In order fur- I0, it being noted as a" *be made in the parts any unintended displacement of the rail with respect to the shelves 40. 1

The valance 24 is then inserted in the manner heretofore discussed, with its upper chamfered margin 25 rearmost, and with the valancefinserted at a slight angle as suggested by the dotted lines in Fig. 4, and the valance is thereafter brought to a vertical position to which its rearward displacement is restricted by the rear wall of the recess 23 and stops 50 of the brackets. The closures 53 having been open-for the reception of the headrail and balance, they may now be closed by upward movement, each about its pivot- 56, so as to bring the closures to substantially vertical position and ment as shown by Fig.- 2.

It will have appeared from the foregoing description that the assembled elements present not only a structurally superior arrangement of the parts as well as one which is highly ornamental and pleasing in appearance, but an arthe ends of the head-- are definitely positioned against movement in any direction. The same advantage applies to the assembled valance which is firmly gripped along its upper margin by-the opposite walls of the groove 23, and at its opposite lower extremities between the stops 50 and the inner vertical face with the latching means provided by bosses 62 and openings 63 in engage- 10 of each of the swingable closure elements 53,

and endwise movement 46. I I

It is to be noted that, by reason of the additional supporting strength derived from the truss relation of the valance 24 to the headrail, a lighter headrail, i. e. one of less thickness or depth, is enabled to be used. For example, in those installations formerly requiring a headrail of 1 stock, I am enabled by the presently improved arrangement to reduce this thickness at least to and yet attain comparable strength without being precluded by steps may be further noted that in accordance with the practice of some manufacturers it was necessary to utilize a U-shaped bracket, on the headrails of all blinds, say in excess of 54" length. By virtue of the present strengthening effect imparted by the valance and the improved bracketing arrangement, center supports need not be resorted to except in blinds of much greater than the noted length.

- It will have appeared that the improvements characterizing the present invention serve fully to attain each of the several objects hereinabove specifically pointed out-,as well as other objects and advantages expressed and implied in the description of the current embodiment.
