Claims.

The present invention relates to a louver construction. More particularly, the present invention relates to a louver and screen assembly which is adapted to be fitted within an ordinary window opening which includes a plurality of pivoted slats moved by upward and downward reciprocating motion of the screen.

The present screen and louver assembly is especially adapted as a substitute for an ordinary glazed sash and screen assembly and is particularly suitable for use in tropical and semitropical climates and for resistance to high winds or the like.

Although in the present embodiment, a louver and screen assembly adapted to fit within an ordinary opening is disclosed, the present invention is by no means limited to such a device, but is also suitable for use as an integral portion of the walls of sun porches or as an integral portion of a door assembly.

One of the objects of the present invention in particular is the provision of a louver construction including pivoted slats which are combined in a novel manner with an operator including a screen frame which may be reciprocated in a vertical manner to open or close the pivoted slats.

A second object of the present invention is a louver operator including a screen frame which utilizes a relatively minor amount of metal without the sacrifice of any strength or flexibility of operation.

A third object of the present invention is to provide a frame adapted to fit within an ordinary window opening or the like, said frame having mounted therewithin a reciprocating screen structure which is linked to operate upon recip rocation a plurality of slats pivoted to the frame.

A fourth object of the present invention is to provide a screen member capable of being reciprocated in a vertical manner within a frame provided with bafiles at the upper and lower ends of th screen member so that such reciprocation does not militate against the effectiveness of the screen.

A fifth object of the present invention is to provide a novel slat operator including a vertically reciprocating frame and a traveler bar provided with pivots for a link member or members extending through slots within the traveler bar and frame so that the link member or members will be free from any side play during motion.

A sixth object of the present invention is to provide a louver assembly including a frame and pivoted slats and a traveler bar connected to the slats and cooperating with the frame to weatherproof the louver assembly.

Other objects and advantages of the present invention will become apparent from the subsequent description and figures of the drawings, wherein:

Figure 1 is a front elevation of the louver assembly with a portion of the screen and frame cut away to show the slats and traveler bar.

Figure 2 is a vertical section of the louver with the slats open.

Figure 3 is a vertical section similar to Fig. 2 with the slats closed.

Figure 4 is an enlarged transverse horizontal section of the louver with the slats open.

Figure 5 is a transverse section similar to Fig. 4 with the slats closed.

Figure 6 is a section taken along the line 6-6 of Fig. 4.

Figure 7 is a perspective detail of a portion of the slat showing the pivot clip mounted thereon.

Figure 8 is a sectiontaken along the line 8-8 of Fig. 6.

Figure 9 is a detail of a portion of the screen frame showing the stop member in operation.

Referring to the figures of the drawings, and particularly to Fig. 1 thereof, a louver including a screen and slat assembly is indicated in general at Ill. The assembly includes a frame II which is adapted to be mounted within a window opening or the like and provided on its inner sides with molding l2 forming a channel for receiving a screen frame l3 which may be reciprocated upwardly and downwardly within the frame H. The screen frame l3 has fastened thereto in any suitable manner, as by molding M, a screen indicated at frame II at the upper and lower ends thereof are members I6 and H which are adapted to seal the upper and lower ends of the screen frame l3 when the screen frame is reciprocated so that vertical reciprocating movement of the screen does not open the same. A handle I8 is also provided on the screen so that the same may be grasped for reciprocation. Mounted to one side of the screen is a clamping member or stop I 9 which includes a handle 20 and a shoe 2! which is moved against the edge of the frame I I when the handle is moved from a six o'clock to 1 a twelve oclock position. In other words, referring to Fig. 9, it will be noted that the handle 20 is in a twelve o'clock position pointing upwardly and the shoe 2| has been moved against the frame H to force the screen frame l3 away from l5. Mounted within the the screen II to a slight extent. This prevents movement of the screen frame I3 upwardly or downwardly, and, as will be hereinafter pointed out, similarly fixes the louver slats in any desired position.

Again referring to Fig. 1, it will be noted that the molding I2 is cut away as indicated at 22 to allow for the operation of the stop member I9. The stop member I9 per se i conventional and any other suitable stop member or means for preventing upward and downward movement of the screen frame I3 in any desired position may be substituted therefor.

Referring to Fig. 2, it will be noted that the screen frame I3 is linked to a traveler bar 23.

by a link 24 which is pivoted on the screen frame by a pivot 25 and on the traveler bar by a, pivot 26. As best shown in Figs. and 6, the link 24 extends into the screen frame I3 and is housed in a slot in the screen frame I3 indicated at 21. Link 24 at its other end is also housed in a slot 28 within the traveler bar 23. As best shown in Figs. 4 and 5, a second traveler bar 29 is also provided at the other edge of the frame and is similarly linked to the screen frame by a link 30 extending into slots 3| and 32 in the screen frame and traveler bar respectively. The link 30 is pivoted similarly to the link 24 on the pivots 33 and 34. The housing of the links 24 and 30 in slots in this manner prevents the links from exhibiting any side play during movement. It will be noted further that the traveler bars 23 and 29 are of a substantial width and are positioned closely adjacent the portions 35 and 36 of the frame II. This also tends to produce a smoothly operating assembly. A pair of angle members 31 and 38 have a relatively wide leg, each attached to the traveler bars 23 and 29 respectively. The free legs of the angles 31 and 38, indicated at 39 and 40 respectively, are provided with openings adapted to receive a shoulder rivet 4| best shown in Fig. 8. The shoulder rivet 4| in turn passes through an eye 42 on a. pivot clip 43 fastened at one edge of a louver slat 44. The pivot clip 43 is also provided with an eye 45 through which extends a pivot member 46 extending from the frame II. It will be understood that each of the slats is thus pivoted at each end on similar pivot members and is similarly attached to the traveler bars 39 and 40 by shoulder rivets similar to the shoulder rivets 4| just described in connection with the single slat 44 so that each of the slats is pivoted at each end both on a stationary pivot and a moving pivot carried by the traveler bar.

A pair of vertically extending strips 41 and 48 are positioned on the inner inside corners of the frame II and are spaced from the outer frame opening as indicated at 49 and 50 to provide a space between the edges of the slats and the frame II into which the free legs 39 and 40 of the traveler bar angles extend when the slats are closed, as best shown in Fig. 5. The traveler bar and strips 41 and 48 thus function as a weatherproofing arrangement for the edges of the closed slats.

The louver construction just described operates as follows:

As shown in Fig. 1, the screen frame I3 is in its lowermost position and the slats are in open position. as shown also in Figs. 2, 4 and 6. At this time the traveler bars 23 and 29 are closely positioned relative to the screen frame I3 and the links 24 and 30 are in the angular position best illustrated in Fig. 6. At this time the member I6 functions as a baflle for the upper end of the screen frame I3 so that the screen is insect proof. If it is desired to completely close the slats, the handle I8 is grasped and the entire screen frame moved upwardly to the position of Figs. 3 and 5. Since the screen cannot move horizontally, the links 24 and 30 will be moved to the angular position shown in Fig. 3 and the traveler bars 23 and 29 will be first moved upwardly and then away from the screen frame I3 into the position shown in Figs. 3 and 5. This movement will rotate the slats about the fixed pivots 46 to close the same. It will be noted that when the slats are closed, the free legs 39 and 40 of the traveler bars will fit between the strips 41 and 48 and the slats, and will s-.rve to weatherproof the edges of the slats.
