LOUVER PIVOT CLIP Filed June 4, 1940 Patented July 13, 1943 LOUVER. PIVOT our Van E. Huff, Miami, Fla., assignor of one-half to Charles F. Miller, Miami Fl Application June 4, 1940, Serial No. 338,799

Claims.

The present invention relates to a louver construction and more particularly to a pivot clip especially adapted to be attached to a louver slat and provided with pivot receiving members.

One of the problems in the louver art has been to provide suitable pivots on which the slats of the louver may be mounted for easy rotational movement. While it is known in the prior art to provide pivot members fastened to wooden or metallic slats, and which are provided with some pivoting means, these members have been difflcult to attach to wooden louvers in a convenient and economical manner and the general,

practice has been to provide a number of pivot receiving members. This has resulted in difliculties of assembly and has in some instances prevented the economical utilization and easy manufacture of louver constructions embodying numerous slats.

One of the objects of the present invention therefore, is to provide a pivot clip construction especially adapted to be utilized in connection with a louver embodying a plurality of movable slats and having a fixed pivot supporting member and a movable pivot supporting member.

Another object of the present invention is to,

provide a pivot clip which is capable of being fabricated in a simple operation from suitable metal as by stamping or otherwise, and has integrally formed thereon a plurality oi pivot receiving members.

Still another object of the present invention is to provide a pivot clip construction embodying struck out members for attaching the clip to a slat.

Another object of the present invention is to provide in a louver construction a pivot clip having at least one of its pivot receiving members ofiset from the clip proper so that a movable portion of louver mechanism pivoted to this pivot receiving member may slide over a fixed portion of the louver construction which is pivoted to another pivot receiving member on the same clip.

A further object of the present invention is to provide a pivot clip construction embodying one pivot receiving portion extending axially outwardly at one end of the clip and another pivot portion extending transversely outwardly at the other end of the clip.

Still another object of the present invention is to provide a pivot clip construction wherein the pivot receiving members are formed integrally from the side portions of the clip and/or connecting or end portions of the clip.

A further object of the present invention is to provide a pivotclip of a general U shape, the legs of the U having integral struck out members for attaching each of the legs of the U to a louver slat.

Other objects and advantages of the present invention will appear from the subsequent description and drawing.

With the above and other objects in view the invention consists in general of certain novel details of construction and combination of parts hereinafter fully described, illustrated in the accompanying drawing, and particularly pointed out in the appended claims.

In the accompanying drawing like characters of reference indicate like parts in the several views, and;

Figure 1 is a perspective ot'a fragment of a louver construction embodying the clip of the present invention.

Figure 2 is a plan view partly in section of a portion of a louver construction embodying the present clip.

Figure 3 is an enlarged elevation of the clip of the presentinvention.

Figure 4 is a plan view of the clip.

Figure 5, is a perspective of a modified form of clip member.

Figure 6 is a fragmentary perspective view ot a modified clip similar to the clipof Fig. 5.

Referring to Figure 1 of the drawing, a suitable louver frame is indicated at l0. Fixedly mounted on the louver frame Ill by any suitable fastening means (not shown) is a longitudinally extending L shaped member H which is adapted to provide a seat or journal for a plurality of pivot members l2. The pivot members I! may be in the form of a hollow or solid rivets and as stated are journaled or rotatably mounted on the free leg of the L shaped member II, as shown particularly in Figure 2. The louver proper is also provided with a movable member or L shaped bar I3, which may be moved upwardly or downwardly by any suitable louver operating member. Such a louver operating member is disclosed in detail in my co-pending application Serial No. 283,500, filed July 8, 1939, now Patent No. 2,257,056, patented Sept. 23, 1941, of which the present application is a continuation inpart.

The L shaped member I 3 is offset sufliciently from the member II that when the louver slats are completely closed the member l3 will slide over the member ii to form a weather stripping for the edges of the louver slats. This provision may be similar in general to that described and claimed in my Patent No. 2,168,347, dated Aug. 8,

1939. It is to be understood that the pivot clip construction described herein is especially adapted for use with a movable and fixed member such as the members i i and I3 which are slidable one over the other and which therefore. must be offset relative to one another. The member I! is adapted to have journaled in one of the legs thereof, a plurality of pivots l4 similar in nature to the pivots it. As shown in the drawing, the pivot members I! and 14 are rotatably mounted in pivot receiving ears II and I6 formed integrally with suitable clip members designated in general by the reference number II. The clip I1 is formed of a pair of relatively flat side portions l8 and I9 connected by a connecting portion 20, so that the clip is U-shaped in crosssection.

Referring particularly to Figure 3, it will be noted that the side portion I8 is shortened so that a portion ofthe material of the side portion may be utilized to form the pivot receiving ear It. The pivot member I is slightly offset rearwardly from the plane of the connecting member 20 as shown in Figure 4. However, this amount of offset is not as great as the offsetting of the member it which must be offset sufliciently to permit the sliding action of the movable bar i3 relative to the stationary bar ll. Both of the pivot receiving members or ears l5 and it are provided with suitable openings 2| and 22 respectively which are adapted to receive the rivets or pivots l2 and I4.

As shown in the drawing, each of the side portions it and I9 are provided with struck out tabs, or lugs, which are adapted to dig into the material of the slat 22a in order to firmly fix the pivot clip on the slat. It will be understood that in the actual louver a great many of these pivots clips are provided and correspondingly great numbers of slats although only one slat is shown in Figure 1 and an additional pivot clip member. The struck out tabs or lugs in each of the side portions l8 and I9 are denoted by the

reference numerals

23 and 24 respectively. As shown in Figure 3 the side portion I8 is provided with two of these struck out members while the side portion i8 is only provided with one, due to its shorter length. In each instance the tabs or

lugs

23 and 24 are joined to the side portions i8 and H at a point remote from the connecting portion III and project into the slat in such a manner that they prevent the removal of the clip from the slat. Although the pivot receiving ear I5 is shown as formed from the material of the side [8 and projected upwardly in Figure 1, it is obvious that it may be formed from the material of the side I!) and projected downwardly without changing the functioning of the device.

It is to be understood that the clip is preferably formed from a suitable thin metal which lends itself to the stamping operations, such as brass and the like, although other materials may he used. Although the clip is shown attached to a slat which is of wood it may be used for receiving a pivot member in connection with slats of other materials, as for example, synthetic wood materials of the nature of masonite, or plastic materials By changing the form of the attaching means it may be used, also in connection with metal slats, slats of glass or slats of synthetic plastics.

Referring particularly to the modification of the clip shown in Figure 5, it will be noted the pivot receiving members here shown are rolled from the material of the opposed relatively flat side portions 18a and Isa which correspond in general to the portions l8 and I! of Figures 1 to 4 inclusive. The side members Ila and lid of Figure 5 are similarly joined by a portion a so that the modified clip here shown is also formed in the shape of the letter U. The struck out tabs '23:: and 24a are entirely similar and have a similar function to the tabs 23 and II of Figures 1 to 4. As shown in Figure 5, the pivot receiving member 26 is rolled from the upper portion of the side I90 so that it projects in an axial direction from the connecting portion 20a. The function of this member is entirely similar to that of the projecting'ear II of the first described modification, and the same offset may be accomplished by lengthening the rolled portion 2! beyond surface 20a, as shown in Fig. 6, wherein the extended portion is indicated by the reference number 20a. Similarly, the rolled over pivot receiving portion 25, which extends from the side portion Ila, may be said to extend transversely with relation to the connecting portion 20a. The functioning of this member is entirely similar, therefore, to the pivot receiving ear member l5 of Figures 1 to 4.

While it may be stated in general that the modification disclosed inIFigure 5 is adapted to receive a heavier pivot for use with heavier slats, it is to be understood that either of the two pivot clips may be effectively used in any suitable louver construction. The pivot clip member disclosed in Figures 1 to 4 is in general simpler to' manufacture, since it does not involve any rolling operation, but may be formed by a simple stamping or series of stamping operations.

While the clip of Figures 1 to 4 is especially designed for use .on an inside jalousie door wherein light plywood slats are used, it is to be understood that it may be proportioned in a larger manner and used on any louver construction and that similarly the clip of Figure 5 could be proportioned to be used on light inside constructions as well as on the relatively heavier slats for which it is especially suitable.

The form of the pivot clip shownin Figs. 1 to 4 inclusive is claimed in applicant's copending appgication. Serial No. 474,745, filed February 4, 1 43.
