United States Patent 3,540,154 JALOUSIE CONSTRUCTIONS Santiago Claudio, San Juan, Puerto Rico, assignor of one-half to Tropicair Manufacturing Corporation, San

Juan, Puerto Rico Filed July 17, 1968, Ser. No. 753,323 Int. Cl. 1206b 7/084 US. CI. 49-91 3 Claims ABSTRACT OF THE DISCLOSURE Improvements are provided in jalousies or similar structures for window, door or other openings, whereby the passage of air or fluids is controlled, and whereby protection against stormy weather conditions can be assured. The edges of the vanes or slats in such structures are provided with improved means for interlocking them and for applying sealing strips or Weatherstripping.

The present invention relates to improvements in jalousie constructions, and particularly to improvements in means for applying sealing strips or Weatherstripping.

Slats in jalousie constructions have, in the past, been found to be frequently ineffective in their operations to seal completely the spaces between them particularly against the highly forceful flow of gases and fluids, or for protection against rain and wind during stormy atmospheric conditions.

An object of the present invention is to provide improvements in jalousie constructions whereby seepage therethrough may be effectively prevented.

A further object is to provide improvements in slats for jalousie constructions effective in weatherproofing metal, wood, or plastic jalousie windows.

Other objects of the invention will also be apparent from a description of means shown by way of illustration in the accompanying drawings in which FIG. 1 is a substantially central vertical sectional view of a jalousie window embodying the invention;

FIG. 2 is a fragmentary, enlarged, elevational, sectional view showing vanes or slats in interlocked, closed position;

FIG. 3 is a fragmentary, elevational, sectional View of a modified vane or slat adjacent the upper end or header of a Window;

FIG. 4 is a fragmentary, elevational, sectional view of a modified vane or slat adjacent the lower end or sill of a window;

FIG. 5 is an end view of a modification of a slat or vane;

FIG. 6 is a front elevation showing a Window opening equipped with a jalousie construction having slats of the present invention; and

FIG. 7 is a section on line 77 of FIG. 6 in the direction of the arrows.

Like characters of reference in the several figures de note like parts of the construction. The operation of the structure is included below with the description of the parts.

Referring to FIG. 1, a plurality of slats or vanes 1 which are pivotally mounted are shown one above the other in the usual manner in a jalousie or shutter construction. In a window, the slats 1 are mounted between a sill 2 and a header 3 and extend across said window from one side jamb to the other. The slats 1 are pivoted at 4 and are operated by conventional means including an arm 5 aflixed to each slat 1 and to an operating bar 6 at 7 which can be lowered and raised to open and close the louvre and bring the slats 1 in and out of the interlocked position.

'ice

Referring to the enlargement in FIG. 2 which shows slats 1 in interlocked position as in FIG. 1, a longitudinal edge of a slate has a lateral extension along one side in the form of a channel 8. Along an edge of an adjoining slat is a flange extension 9, the free edge 10 of which projects into the channel 8 of the first-mentioned slat 1, as shown, when the slats are in closed position. Upon pivoting the slats to open position the edge 10 of the flange 9 is withdrawn from the channel 8.

A sealing strip 12, of rubber, neoprene, vinyl, or other suitable, flexible, pliable or resilient material, coextensive in length with the length of a slat, projects laterally into a channel 8 from the inner side 13 of the outer wall 14 of said channel 8. An edge of the sealing strip 12 is fastened to the wall 14 in the usual manner, as by means of a retaining groove 15 and a widened portion 16 of the sealing strip material that is held in such groove. The opposite edge 17 of the sealing strip is adapted to engage the near side 18 of the flange 9 of the adjoining slat 1 as it moves into interlocking position upon closing the louvre. Upon so doing, the sealing strip is flexed and it seals the space between the side 18 of the flange 9 and the side 13 of the channel wall 14. By plastic memory the strip 12 returns to its original shape tending to reach a position at right angles to the wall 14 and across the path of the flange 9, when the louvre is opened.

Integral with a slat 1 and projecting laterally from adjacent the edge thereof from which the flange 9 projects, and in the direction of the adjoining slat 1 crosswise of the adjacent channel 8, is a narrow ledge 20 provided with a retaining groove 21 by which a sealing strip 22 with a widened portion 23 is held in place as in the manner of sealing strip 12. The ledge 20 extends the length of the slat 1, and the groove 21 extends the length of the ledge 20. The sealing strip 22 projects laterally from the side 24 of the ledge 20 facing the edge of the adjoining slat 1 to which the channel 8 is connected. When the edge 10 of the flange 9 touches the wall 25 of the channel 8, the side 24 of the ledge 20 is spaced from the outer surface 26 of the adjoining slat 1. The sealing strip 22 is of sufiicient width and is so positioned that it is across the space between the side 24 and the surface 26, and is flexed to provide a seal when the slats are in closed position.

The positions of the slats 1 are interchangeable in a jalousie construction, but if desired, the slat 1 adjacent the header 3 of a window may be modified by omitting the channel '8 shown in FIG. 1 to provide a slat 27 in this position without a channel 8, as shown in FIG. 3. Also, if desired, the slat 1 adjacent the sill 2 of a window may be modified by omitting the ledge 20 shown in FIG. 1 to provide a slat 28 in this position without a ledge 20, as shown in FIG. 4.

To seal the space between the top slat 1 in FIG. 1, or the slat 27 in FIG. 3, and the header 3 of a Window, a sealing strip 29 extending in length across the width of the window, projects laterally from the inner side 30 of the front Wall 31 of the header 3 to the outer side of the slat 1 (FIG. 1) or of the slat 27 (FIG. 3). The sealing strip 29 is held in place by a retaining groove 32.

To seal the space between the bottom slat 1 in FIG. 1, or the slat 28 in FIG. 4, and the sill 2, a sealing strip 33 extending in length across the width of the window, projects laterally from the lower side 34 of the sill 2 adjacent the front edge thereof to the inner side 35 of the flange 9 of slat 1 (FIG. 1) or of slat 28 (FIG. 4). The sealing strip 33 is held in place by a retaining groove 36.

The sealing strips 29 (FIGS. 1 and 3) are flexed by and are pressed against the outer surface of the top slat 1 and slat 27 as these slats are moved into closed position. The sealing strips 33 (FIGS. 1 and 4) are flexed 3 by and are pressed against the inner side 35 ofthe flange 9 on the bottom slat 1 (FIG. 1) and on slat 28 (FIG. 4) as these slats are moved into closed position.

As shown in FIG. 5, a modified slat 38 is formed with merely a flange 39' at one edge, corresponding to the flange 9 on slat 1, and with an extension on the opposite edge providing a channel 40 corresponding to the channel 8. The Weatherstripping retaining grooves 41 and 42 may be attached to the slat 38 in separate elements 43 and 44 respectively. The element 43 is so attached to the slat 38 that the groove 41 is positioned along the length of the slat 38 adjacent the angle formed by the flange 39 and the main portion of the slat, and is so positioned that a Weatherstrip 45 held by the groove 41 projects sidewise therefrom toward the outer surface of an adjacent slat (not shown) and is flexed thereby and held tightly against it when the slats are in closed position. The element 44 is so attached to the slat 38 that the groove 42 is positioned along the length of the slat 38 adjacent the free edge 46 of the outer wall 47 of the channel 40, and so that a Weatherstrip 48 held by the groove 42 projects sidewise therefrom toward the inner surface of an adjacent slat (not shown) and is flexed thereby and held tightly against said surface when the slats are in closed position.

The spaces between the jambs 49 and 50 of a window opening 51 (FIGS. 6 and 7) and the outer ends of the slats in the jalousie construction described hereinabove,

may be sealed by means and in a manner well known in the art, or by other means. Weatherstrips 52 and 53, for instance, projecting sidewise from grooves 54 and 55 respectively, in the jambs 49 and 50 respectively, toward the ends of the slats, and extending vertically from the sill 2 to the header 3 of the window, are flexed by the slats 1 and are brought tightly against them whereby the spaces between the jalousie and the jambs are sealed.
