Application December 20, 1954, Serial No. 476,178

4 Claims. (Cl. 20-62) This invention relates to an improvement in retainer clips for holding jalousie window panels in place.

One of the disadvantages of a commonly used retainer clip for jalousie panels is that the clip must be bent by a pair of pliers in order to dispose a retaining tongue adjacent the panel. Repeated bending of this retaining tongue may cause it to break so that the entire retaining clip becomes useless. Moreover the area of contact between the retaining tongue and the glass is small, so that the panel is not firmly held and thus may be easily rattled.

It is an object of this invention to provide a retaining clip which firmly locks the jalousie panel to the framework.

It is another object of this invention to provide a retaining clip having a spring loaded wedge-shaped movable element adapted to engage a substantial area of the panel in a wedge functioning relationship.

It is a further object of this invention to provide a spring-loaded wedge means for wedging a glass panel firmly in place in a jalousie construction.

These and other objects of this invention will become apparent upon reading the disclosure taken in conjunction with the accompanying drawing in which,

Fig. 1 is a partial side view of a window construction and showing a pair of retaining clips,

Fig. 2 is a view of the window construction of Fig. 1 with the panels in an open position and showing in dotted outline the manner of moving the retaining wedge in order to remove the glass panel,

Fig. 3 is a rear view of the retaining clip,

Fig. 4 is a perspective view of a single jalousie glass panel held in place by a pair of retaining clips,

Fig. 5 is a side view showing the manner of inserting a glass panel,

Fig. 6 is a view similar to Fig. 5 but showing the insertable panel in another position,

Fig. 7 is a section view of the retaining wedge of Fig. 6,

Fig. 8 is a section view taken on line 88 of Fig. 7,

Fig. 9 is a view of the retaining wedge blank prior to being folded into a wedge,

Fig. 10 is a side view of the right clip blank, shown in Fig. 4,

Fig. 11 is a side view of the left clip blank shown in Fig. 4, and

Fig. 12 is a section view of a modified retaining wedge showing a bow-spring in lieu of the coil spring of Fig. 8.

Referring to Figs. 1 to 4, a left panel clip 10 and a right panel clip 11 (Fig. 4) are removeably secured to a plate glass panel 12. The right panel clip 11 is provided with a pivot aperture 13 and a hinge aperture 14. The pivot aperture 13 is journaled by conventional means to the fixed frame work 15 and the aperture 14 is journaled by conventional means to a travel bar 16. A plurality of right panel clips are swingably secured in spaced relationship to bar 16 (Fig. 1), so that movement downwardly of bar 16 causes all panels to move outwardly (Fig. 2).

As shown in Fig. 4, only the right panel clips 11 are secured to a travel bar 16.

Referring to Figs. 10 and 11, the left clip 10 and the right clip 11 are identical with the exception that the right clip 11 is additionally provided with hinge protuberance 17 having a hinge pin aperture 14.

As shown in Figs. 10 and 11, the left clip 10 and the right clip 11 are cut or stamped from a single sheet of material, preferably aluminum sheet metal and are provided with a central panel area 18, which is vertically disposed in the assembled jalousie window or door assembly, and a plurality of bendable panel areas.

A front bendable panel area 19 is adapted to engage the front face of the plate glass panel 12 and is provided with a bottom support arm 20. In the prepared clips 10 and 11 the panel areas 19 are bent inwardly at right angles to the central panel area 18 and the support arm 20 is itself bent inwardly at right angles to panel area 19 and in touching and adjacent relationship to the central area 18 (Figs. 5 and 6).

The central panel areas 18 of both the left and the right clip are provided with a bendable tab 21 adapted to engage the top edge of a glass panel 12.

The central area 18 is further provided with a bendable panel area 22 disposed in angular relationship to the panel area 18 and providing a slideway support for a wedge piece to be described later.

The panel areas 22 are bent inwardly at right angles to central panel area 18, but because of the slope of the fold or bendline the panel is disposed at a slope to the vertical plane.

The tab 21 and support arm 20 are of a width substantially that of the plate glass panel 12. The support arm 20 being a load bearing arm and supports the weight of the glass panel 12.

As shown in the drawing the central panel area 18 is provided with a suitably located opening 23 formed by stamping out a spring retaining tab 24 (Figs. 8 and 9).

An important feature of this invention is the provision of a spring loaded slideable wedge which is slideably disdisposed on area 22 and which is adapted to engage the rear surface of a glass panel 12 with a locking force or seizure.

The wedge itself is preferably prepared from a flat blank of sheet metal (Fig. 9) preferably of aluminum, by folding the lateral longitudinal and slide areas along fold line joining a central trapezoidal area 24X.

The area 24X is integral with a top bendable area 25 and a bottom bendable area 26 of lesser size than panel 20. A rectangular side panel 27 is integral with the vertical longitudinal edge of the trapezoidal panel 24X (Fig. 9). A second rectangular side panel 28 secured integrally to the oblique edge 28 of trapezoid 24X is provided with a finger tab 30. The finger tab 30 is provided with cut-lines 31 so that it is in effect the end portion of a bendable tongue piece.

In preparing the wedge from the blank shown in Fig. 9, the slide and the top and the bottom areas are bent inwardly, forming a hollow wedge of trapezoidal configuration and open on a lateral side (Fig. 4), said open side of a respective wedge being disposed against the inner surface of a panel area 18 of a corresponding clip 10 and 11.

As shown in Figs. 10 and 11, each of the clip panels 22 is provided with a centrally disposed longitudinal slot 32 adapted to receive a bent tab (Fig. 4).

The wedges are spring-loaded, with preferably a helical coil spring 33 (Fig. 8) or a bow-spring 34 (Fig. 12), disposed between tab 24 of a respective clip 10 or 11 and the panel 26 of a co-acting wedge.

The tab 24 and panel 25 may be, if desired, provided with stamped protuberances 35 for holding the coil spring 33 in place (Fig. 8). In the case where a bow-spring 34 is employed (Fig. 1.2), the ends of the spring 34 are inserted in a co-acting aperture in a respective tab 24 and panel 26 and then bent over in locking engagement with said tab 24 and panel 26.

In assembly of the wedge to the clip, the spring 33 or 34 may be inserted through the opening 23.

The movement of the wedge is shown in Figs. 2 and 12, and more particularly by comparing Figs. 5 and 6. As shown in Fig. 5 the wedge is disposed in its natural unlocking position in closest relationship to support arm 20. Fig. 6 shows the moved position of the wedge during the operation of inserting a glass panel 12, the wedge being moved upward by frictional contact between the wedge panel 12 and the corresponding co-acting surface of the glass panel 12. The panel 12 is pushed inward manually until the bottom edge of the glass panel 12 is pushed over the lip of support arm 20 and then seated on said arm 20 and in planar relationship to panel 19.

To remove the glass panel from a clip the tabs 30 of the clips 10 and 11 are moved upward causing the wedge to move upward and away from the glass panel 12 (Fig. 2). The glass panel 12 is then pushed inward until its outer face is over the lip of the clip panels whereupon the panel is pushed downward and removed.

As shown in Fig. 4, the fiat surface of the respective panels 27 of clips 10 and 11 engage the glass panel 12 in planar and wedged relationship so that the glass panel 12 is firmly, solidly and immoveably held in place until released by manual operation.

This invention has been illustrated by means of a plurality of embodiments but it is not to be limited to these embodiments because it is of a broader scope.
