The louver-engaging spring, which serves to positionably lock the louver in its bracket, is normally provided at its upper end with a lip for engaging the upper edge of a standard size of louver to prevent any upward displacement thereof from the supporting bracket. The locking spring is so designed that its said upper end portion may be cut-off to adapt the bracket for support of a louver which is of a narrower width than the standard size louver normally accomodated in the bracket.

10 Claims, 4 Drawing Figures US. Patent Dec. 30, 1975 JALOUSIE LOUVER BRACKET This invention relates to jalousies and more particularly to improvements in the construction and design of the brackets in which are removably supported the swingable louvers or panels ofjalousie windows, doors and the like.

Among the principal objects of the present invention is to provide a unique and simple construction of the bracket which is not only inexpensive to manufacture but also extremely simple to install in thejalousie frame for quick and easy insertion and removal of the jalousie louvers into and out of their operative positions.

A further important object of the invention is to provide a swingable jalousie bracket having a quickdetachable spring member which effectively resiliently engages the jalousie louver at threespaced points to positively hold louver securely in its supporting bracket by simple rectilinear insertion of the louver between a base part of the bracket and its associated louverretaining spring.

A still further object is to provide a jalousie bracket or clip which permits insertion and removal of the jalousie louver from the indoors side of the jalousie frame by simple rectilinear movement of the louver in its own plane into and out of a secure and positive retained position in the bracket.

Still another object is to provide a louver mounting bracket having a louver engaging spring member which forms a self-interlocked part of the bracket assembly for insuring safe insertion and removal of the jalousie louver and which spring member may be easily reduced in its overall length without impairing the ability to safely and adequately employ the bracket of which it forms a part for accomodating a louver which is of narrower width than those which may be supported by the brackets having full length spring members, thereby permitting off-size jalousie frames to be fitted with one or more swingable louvers of less than standard width as may be required to provide the frame with a full complement of overlapping louvers.

Other' objects and advantages of the invention will appear more fully hereinafter, it being understood that the invention consists in the combination, construction, location and relative arrangement of parts as hereinafter described in detail, as shown in the accompanying drawings and as pointed out in the appended claims.

In the accompanying drawings:

FIG. I is a perspective view showing in exploded form the component parts of the bracket as constructed in accordance with the present invention for removably mounting the louver or panel in the frame of a jalousie window or door;

FIG. 2 is an inner side elevational of the bracket shown partially in section showing one end of a louver in engagement with and supported by said bracket;

FIG. 3 is a transverse sectional view as taken along the line 33 of FIG. 2; and

FIG. 4 is an elevational view of a vertical section of one side of a jalousie frame assembly which includes therein the louver supporting brackets of the present invention.

Referring now more particularly to the drawing, it will be observed that the jalousie louver-supporting bracket or clip of the present invention is made of two separate parts, namely, a main bracket member and a locking spring 11 made of suitable spring metal such as, for example, flat stainless steel, which is quickdetachably connected to the bracket member 10 to serve as a resilient device for securely locking the vertically spaced louvers 12 into their supporting brackets as shown in FIG. 4. Each of the several louvers or panels which make up the complete jalousie is-supported at its opposite endsby a pair of the supporting brackets and to this end each such pair of the brackets are mirror images of one another.

The main bracket member 10 includes a vertically extending part 13 having an inturned bottom flange or lip 13a which serves as a supporting base for the louver or panel 12 carried by the bracket. Formed integrally with and extending at right angles to the base part 13 is a flat mounting arm 14 having an upwardly inclined coplanar extension 15, which arm 14 is apertured, as at 16 and 17, to receive pivot studs or rivets l8 and 19 for respectively pivotally securing the bracket to a fixed side of the jalousie frame 20 and to a vertically reciproeable actuator bar 21 which is conventionally disposed on either side of the frame for vertical shifting movement by means of an operating handle and linkage (not shown) well known in the art.

The bracket arm 14 is provided with a pair of vertically spaced parallel lugs or ears 22-23 which extend crosswise of and are each spaced from the base part 13 a distance sufficiently greater than the thickness of the louver which is carried by the bracket to enable the louver to be inserted flatwise between said base part 13 and the proximate edges of the lugs or ears 2223. Each of these lugs or ears is provided with an openended slot 24 (as seen FIGS. 1 and 3) the outer end of which is partially closed off, as at 25, to provide a reduced entrance way into the slot. The length of the slot 24 beyond it restricted entrance 25 is just slightly greater than the width of the spring 11, while the slot entrance 25 is of a width which just allows free passage of the spring 11 sidewise into its accomodating slot.

The locking springs 11, except as modified in the manner and for the reason hereinafter described, is of the pre-shapedform best shown in FIG. I from which it will appear that said spring is of an overall length somewhat less than that of the base part 13 of the bracket and also less than the width of the louver which the bracket is designed to support. The locking spring 11 is inturned at its upper end to provide a lip 26 which fits over and closely engages the upper edge of the bracketsupported louver and is provided intermediate its opposite ends with an outwardly projecting section 27 having the stepped configuration best shown in FIGS. 2 and 3. This stepped projection is located at a point along the length of the spring to enable it to be nested within the slot 24 of the uppermost lug or car 23 of the bracket member 10.

As will be noted, the projection 27 of the locking spring 11 is of a nose-shaped form having a downwardly and forwardly inclined upper section 28 and a Z-shaped lower section 29 interconnected by a frontal bridging section 30. The Z-shaped section 29 includes a pair of vertically. spaced substantially horizontally disposed

branches

31 and 32 and a central vertically extending branch 33 which conjointly operate to securely hold the spring 11 in its louver-locking position when said spring is interfitted into the slotted lugs or ears 22-23. In this interlocked condition of the spring 11, the branches 3! and 32 of its Z-shaped'section 29, which are horizontally offset to either side of the central branch 32 thereof, respectively overlie the top and bottom surfaces of the upper lug 23 so that when the central branch 33 of said Z-shaped section of the spring 11 is moved edgewise into its accomodating slot in the upper spring-supporting lug 23 and the lower portion of the spring is correspondingly moved into the slot of the lower lug 22, the spring is held restrained against any shifting movement longitudinally with respect to the base part 13 of the bracket member.

It will be noted that the portion of the spring 11 which extends below the nose-shaped projection 27 is reversely bowed to provide a pair of longitudinally spaced portions 34-35 which are adapted to respectively resiliently engage correspondingly spaced portions of the bracket-supported louver for holding it firmly in position against the base part 13 of the bracket. Also, it will be observed that the reversely curved portion of the spring 11 is nested in the bottom slotted lug 22, thereby providing a two-point interlock between each spring and its associated bracket member 10 to prevent any tendency for the spring to skewout of its proper louver-engaging position which desirably should be along a vertical line paralleling the longitudinal center line of the bracket base part 13. It will also be apparent that when the spring 11 is seated as shown in the slotted lugs or

ears

22 and 23 the opposite end portions thereof which project outboard of said lugs, as well as the central portion thereof which extends between said lugs, are all inherently biased toward the base part 13 of the bracket for three point holding engagement with the louver when the same is inserted between the spring and its underlying base part 13.

In order to mount ajalousie louver or panel between a pair of the spring-fitted brackets of the present invention, it is only necessary to press the top ends of the springs inwardly, i.e., away from their associated base parts 13, sufficiently to permit the louver to be shifted downwardly into position between said base parts 13 of the paired bracket members and the retaining springs associated therewith until the bottom edge of the louver is seated against the bottom flanges 13a of the supporting brackets. The locking-springs 11 are of course normally so designed that when the bottom edge of the louver is seated upon the bottom lip or stop 13a of the base part 13 (as best shown in FIG. 2), the inturned tops 26 of the locking springs automatically spring over the top edges of the louver to hold it secured against unintentional vertical displacement. To remove a louver, it is only necessary to reverse the above described procedure, i.e, disengage the top ends of the springs 11 from the louver sufficiently to permit the latter to be vertically lifted free of its supporting bracket. It is an important feature of the present invention that the operations of insertingand removal of the louvers relatively to their supporting brackets are performed from the inside of the jalousie frame.

Another important feature of the bracket of the present invention is that it may be easily and conveniently altered to accomodate a louver which is of a somewhat reduced width as is often required when fitting a jalousie frame with a series of louvers of a uniform size which conjointly leave a space to be fitted which is of less vertical dimension than that of the uniformly sized louver. To accomplish this, it is only necessary to cut off a portion of the spring at a point just above the nose-shaped projection 27, as along the dashed line A--A of FIG. 1 and as shown as at 36, in the case of the locking springfor the topmost louver of FIG. 4. The upper free edge of the cut-off spring 11, because of its pro-shaped form, still functions through its inherent 4 resiliency to bear against the top portion of the relatively narrow louver to hold it firmly pressed against the base part 13 of the bracket. In all other respects the altered bracket functions in the same manner as that previously described and shown in FIG. 2 to securely hold the off-size louver or panel in place.

It will be understood that the present invention is susceptible of various other changes and modifications which may be madefrom time to time without departing from the general principles or real spirit thereof and it is intended accordingly to claim the same broadly, as well as specifically, as indicated by the appended claims.-
