Application August 15, 1949, Serial No. 110,390

This invention relates to an ornamental valance unit, and has particular reference to an ornamental valance unit for use in kitchens, pantries, or other work areas.

It is an object of the present invention to provide an ornamental valance unit of improved design adapted to be installed between the upper, opposed portions of two spaced wall cabinets, or the like and which is so constructed that it may be installed between such cabinets even though there is a considerable variation in the spacing of such cabinets along the wall.

It is a further object of the present invention to provide an ornamental valance unit having means thereon for supporting within the unit, an illuminating device such as a fluorescent tube or tubes, which tube or tubes are supported entirely by the unit and are positioned behind the front face thereof to cast their light downwardly and, if desired, also upwardly, to illuminate the sink, drainboard, table, or other Work area adjacent the unit.

It is a further object of my present invention to provide an ornamental valance unit, preferably. one having illuminating mean therein, and including means for supporting a window curtain or drapery of either the roller or sliding type.

A still further object of my present invention is to provide an ornamental valance unit that is relatively cheap and easy to manufacture, is strong and durable, which serves to support illuminating means and curtains or draperies, which permits ready access to such illuminating means for the purpose of replacement and repair, which may if desired, support on the outer face thereof a clock, fan, radio speaker, or the like, which may be sold and installed as a unit, which is easy to install between the opposed side faces of spaced cabinets, which may be readily removed, and which is highly eflicient in the purposes for which designed.

The abovementioned objects, and further objects of the present invention, will be apparent from the following description of preferred embodiments of the invention as shown in the accompanying drawings, in which drawings:

Fig. 7 is a perspective view of a modified form of front plate for the unit.

In the accompanyingdrawings, wherein like reference numerals have been employed to designate like parts throughout the several views,

there are shown in Fig. 1 two wall-mounted kitchen cabinets l0 and II of any well known or preferred construction, one of which is mounted on the wall at each side of a window l2 shaded by a Venetian blind l3, and above a sink I4 having the usual drainboards extending from the sides thereof. The cabinets l0 and H have hinged doors Ill and I l respectively, equipped with the usual handles or pulls as shown, and have opposed, substantially parallel side walls lfl and ll respectively, between which the ornamental valance unit of the present invention is mounted. The cabinets Ill and l I may, of course, be of several different types, i. e. they may be mounted in longitudinally-spaced relation along a wall and be supported from the wall, they may be relatively high cabinets supported from the fioor, they may have sliding instead of swinging doors, they need not be mounted above a sink or at opposite sides of a window, etc. 1 Referring particularly to Fig. 5 of the accompanying drawings, it will be noted that this figure illustrates one of the two end pieces consti-' tuting a part of the valance unit and which means thereon, and preferably formed integrally therewith, for supporting the illuminating tubes,

the curtains, or draperies, and other parts to be hereinafter described, this plate I5 being located at the left end of the unit, and a similar plate 16 being located at the right end of the unit as viewed in Figs. 1 and 4, it being understood that plates I5 and I6 are mirror images of each other and are identical except for the location of certain parts. With this understanding, a detailed description of the left end piece l5 will, it is believed, sufiice for both of said end pieces I5 and I5.

End piece I5 has a top marginal flange H extending at right angles to the body of the said piece and adapted to fit over, and in somacases to be secured to, the top of the cabinet I. At approximately the center of the end piece I are two parallel, inwardly projecting and vertical y disposed tabs I8 and I9 which are out from the metal plate to provide supportsforthe fluorescent lighting unit, which, as shown, may be of thedual or, double type consisting of two fifit'rsceht tubes at and 2| removable ni'oilnted ona supportlz which may carrythe starter (not Shawn) for the tubes. Support 22 may have the shape of anopen-ended, elongated channel membe of inverted U shapedtr'an'svrse cross sectio and is adapted to fit snugly over the inwa dly projcting tabs I8, a n'd I9. the front edge 6f piece I5, a flange 25 is bentat right angles to the plane of the plate and in a directiono'pposite to that in which flange I! is bent. A pair of ear sor tabs 26 and '21 are bent inwardly from plate, I5 and extend parallel to eachother and to gauge '25. Several holes28 are provided through plate I5 to facilitate its attachment by screws or the like to the ehd wall I0 as will be readily aflbarent from Fig. ,4.

'The front of the unit comprises a sheet or peters, which provides asmooth panel extending in a vertical plane between the two spaced cabinets with the upper edge of sheet prplate 2 9 in the same plane as the tops of the cabinets Ill and I l as shown in Fig. l, or, in install ations where the to s of the cabinets reachthe ceiling, with the sen lll pr edge of sheet or plate 29 spaleeqeighuy below the plane of the topsof the said cabinets so that light from the fluorescent fillies 2P e d. l a mi eeieveri e top e e o sheet or plate to be reflected from the ceiling and i to t rooin in which the unit is installed.

or liftingfit 'olf it'sfsupports and then and once this panel is removed, the fluorescent tubes 20 and 2| and their associated starter and other parts are readily accessible from beneath for purposes of replacement or repair.

Along the top edge of the front sheet or plate 29, there is provided a horizontal flange 39 which terminates in a vertical depending flange 40, the latter being apertured to receive a bolt 4| which secures the upper edge of the front sheet or plate 23 to the ear or tab 26. The front sheet or plate 29 is of suflicient inherent resiliency to be sprung over the ears or tabs 25 and 21 at each end of the iinit prior to being secured to the end pieces I5 and I5 by bolts 33 and 4|.

Instead of employing the one-piece sheet or plate 29 as the front of the unit and which sheet or plate is cut off at its end or ends to snugly fit the space between the two cabinets, I may employ a readily, adjustable front of the construction shown in Fig. 7, wherein two corrugated or longitudinally ribbed sheet metal members 42 and 43 are slidably joined by acentral corrugated or longitudinally-ribbed bridging member 44. The three members which constitute this modified form of front are provided with inturned flanges, at tlieir upper a nd lower edges, the lower inturned edges servingto support the panel 36 as above disclosed in connection with the other formpf front, and for attachmentof the front, by screws AI and 33 to the ears or tabs on the end pieces or brackets I5 7 and I6, as will be understood without illustration. In other words, the f nt constructed as illustrated in Fig. '7 perorm t 3 iim i naen i eupberted in the same manner, as the front 29, the only important difference being that the front illustrated in Fig. 7 consists of parts which are longitudinally adjustable so as to be usable in instances where there is a variation in the distance between the opposed walls of the longitudinally-spaced cabinets. The dotted line icirclein Fig. 7 shows the preferred location for the clock face, or other device which may be associated with, or mounted on, the front of central section 44.

I In themajority of installations, an ornamental valance unit such as that presented herein, is mounted above a window as illustrated in Fig. l, and to accommodate a window curtain or shade for the window, :the end pieces I5 and I6 are provided with special supports. These supports may take the formof an inturned ear or tab 45 which extends at rightangles to the plane of end piece I5 and at, the rear, vertical edge thereof, as best shownir Fig.5. The ear or tab 45 forms a vertical abutment for a curtain, shade, or drapery pocket member 4'6, which may consist of an elongated channel member of invertedU-shape transverse cross-section. A'horizontal abutment for the pocket member 46 is provided by a horizontal, -inturnfed ear or tab t! struck outfrom end piece I5 and at right angles to the general plane thereof; =A bolt 48 is passed through the member and through an-aperture in ear or tab 41 to connect the pocket member 46 to the end piece I5. A ledge or bead l-9, square in transverse cross section is .p rovided along the lower front edge of the pocket member 45 and fits over the ears or tabs 3 1 and 33 to serve as a supportfor the rear edge of the light transmitting and diffusing panel 36, or, if preferred, panel 35 may restfdirec'tly upon ears or tabs 3"! and 38. As

clearly shown in Fig. 2, the p'oc'ke t member I6 provides a recess in the base of the unit, the walls of which;ri e ces;s effectively conceal the curtain or drapery rod 50. which rod is hollow and may be or the slidable, telescopic type so that, itsends will readily slip over inturned ears or tabs which are struck out from the end pieces l5 and IE to support the rod 50. The flat top of pocket member 46 may be effectively utilized to support the ballast (not shown) usually employed in connection with fluorescent lighting units.-

In the modified form of the present invention shown in Fig. 6, I employ in lieu of end pieces l5 and I6, three separate parts designatedgenerally by the reference numerals 52, 53, and 54, which parts are adapted to be secured by screws or bolts to the outer opposed faces of the longitudinally spaced cabinets Ill and H to serve as supports for the other members which make up the ornamental valance of the presentinvention, such as the front, the fluorescentlighting units, the curtain or drapery pocket, etc. Part 54 is one of two similar parts which secure the front sheet or plate 29 or the modified front plate shown in Fig. '7, in proper position relative to the cabinets. This part consists of a flat strip provided with an inturned flange 55 which functions in the same manner, and for the same purpose, as flange 25 previously described. A top flange 56, also at right angles to the plane of the fiat strip, serves to support the front sheet or plate 29 by its longitudinal top flange 39. Ears or tabs 51 and 58 correspond in function to ears 26 and 21, respectively. If preferred, the front sheet or plate 29, or the modified form of front shown in Fig. '7 may be provided at its opposite ends with vertically disposed strips 59, the outer edges of which are positioned in spaced, parallel relation with respect to the rear surface of the front 29 of the unit, the inner edges of saidstrips 59 being welded or otherwise permanently secured to the rear surface of said front, thus forming an open ended pocket at each end of the front into which pocket the vertical flange 55 may fit.

Part 52 comprises a four-sided member adapted to be secured by a screw or screws (not shown) passed through its wall 60 and into the cabinet wall lfl or II. The channel shaped support 22 for fluorescent tubes 20 and 2| will have its ends supported by the part 52, in the same manner in which the support 22 is supported by ears or tabs I8 and I9 previously referred to.

Part 53 comprises a substantially square base plate 6| with a marginal flange 62, one lower corner of which is provided with a square ledge or bead 63 on which the inner edge of the panel 36 rests, it being understood that the forward edge of said panel is supported on the ears or tabs 58 of member 54. An inwardly-projecting, struckout ear or tab 64 is located centrally of the base plate GI and provides a support for one end of the curtain rod or shade and functions in the same manner as ear or tab 5|.

It will be understood that the valance unit above described should be equipped with the necessary electrical connections and leads, in cluding a three wire lead adapted to be plugged into a wall outlet or otherwise connected to a source of electric power, the lead consisting of one neutral wire, one hot wire to provide continuous current for an electric clock, fan, or the like, and one wire connected to a wall switch (not shown) to provide for selective use of the fluorescent lighting unit.

When the tubes 20 and 2| are energized by actuation of the controlling switch therefor, the light rays will pass upwardly to the ceiling since the unit is completely open at the top, and such light rays will also pass downwardly through 6 panel 36 by which the light will be diffused be fore it reaches the sink, drainboard, or other area beneath the unit. If desired, the light rays may also pass through the front of theunit, as

the latter could well be made of any one of a number of transparent materials, such as glass, synthetic resin, or the like. It will be obvious that the ornamental valance unit of the present inventionmay be painted or otherwise finished on its exterior to match the color of the cabinets or to contrast pleasingly therewith. All unsightly mechanical parts of the mechanism contained within the unit are concealed, and the unit will add considerably to the appearance, as well as to the comfort and convenience, of the room in which it is installed.

It is to be understood that the forms of the invention shown and described herein are to be taken as preferred examples of the same, and that various changes may be made in the shape, size and arrangement of parts without departing from the spirit of the invention or fromthe scope of the subjoined claims.
