Kundrat [57] ABSTRACT Joint adapted to interconnect the ends of two adjacent side members of the frame of a shutter. This frame comprises a side member parallel to the direction of movement of the shutter, side member which is a metal shape having a solid elongated central web provided on either side with a pair of longitudinal flanges projecting from the Web, the said pairs of flanges respectively defining an outer channel for the reception of a slide bar to guide the shutter and an inner channel; the flanges defining the inner channel terminating short of the end of the web to define transverse shoulders whereas the flanges defining the outer channel extend beyond the web. The latter further has a transverse groove between the transverse shoulders and its end. The other side member is a metal shape having two parallel side cheeks of which the outer faces fall respectively in the same parallel planes as the outer faces of the flanges of the other side member. These side cheeks have inwardly projecting strips and a bight that extends parallel to the strips, the latter and the bight being located at constant distances respectively from the longitudinal edges of the side cheeks to define inner and outer channels. A joint made in this manner is formed by inserting the strips of the cheeks into the grooves of the other side member, the inner edges of the cheeks then bearing against the shoulders of the other member.
2 Claims, 4 Drawing Figures US. Patent Dec. 9, 1975 JOINT FOR WINDOW SHUTTER that enter into the ends of the side members-forming the joint. These screws must extend in, .a direction which is transverseand perpendicularjto direction of movement of the window shutter so that the joint may resist the force necessary to move the, shutter. It is obvious that the screwing of four screws in each shutter means labor cost which correspondingly reflects in the manufacturing cost of the window which would usually have several such shutters. It is also obvious that if the use of such screws could be avoided, the manufacturing cost of the window would correspondingly be lower. It
is precisely the object of the present invention which 2 suggests a window shutter of which the side members can be interconnected and held in position without the use of screws and without any danger that the joints would break apart when the shutter is forcibly displaced.
More specifically, a joint made according to the invention is characterized by the provision of a channel formed at the end of one of the two adjacent side members that make up the joint, channel having strips projecting from two opposing faces and extending transversally of the aforesaid direction. The joint further comprises a male part formed at the end of the other adjacent side of the joint and inserted in the said channel. The male part is provided with grooves on opposite faces, which grooves receive the strips in such a way that when the shutter is moved in the aforesaid direction, the strips in the grooves prevent severing of the two sides forming the joint.
The invention will be better understood by the description that follows of a preferred embodiment thereof having reference to the appended drawings wherein:
FIG. 1 is an exploded perspective view illustrating the two side members of a shutter forming a joint according to the present invention;
FIG. 2 is a plan view of a corner of the shutter, with part broken away to show inner features;
FIGS. 3 and 4 are cross-sectional views respectively taken along lines 3-3 and 44 of FIG. 2.
Referring now to the drawings, the joint according to the invention is shown as applied to a window shutter 1 adapted to be moved in its own plane and in opposite directions shown by the arrow A. It will be understood that a window generally comprises several of such shutters that may also be of different sizes.
The joint shown in the drawings interconnects the ends of two side members 3 and 5 of the window shutter 1, the side member 3 extending transversally and perpendicularly to the direction A whereas the side member 5 extends parallel to the said direction. A channel 7 is formed at the end of the side member 3 and is provided with strips 9 projecting from the two opposed faces 11 of the channel 7, the strips extending LII 2 into the grooves 15 and it will thus be understood that when-the shutter 1 is displaced in the direction A, the force necessary tomove it will be resisted by the abutment of the strips 9 against the sides of the grooves 15 andit will neither. be necessary nor useful to secure the joint by means of a screw as waspreviously required to resist the force tending to sever or separate the parts 3 and 5 when the shutt er became jammed. .The afore-described joint is particularly applicable in thecase where the shutters 'have sides made out of metal shapes, for instance steel or aluminum. In such a Ease, the side member 3 will have a U-shaped channel formed'by the aforementioned opposed cheeks 11 and ,zfbight' 17 located upstream 'with respect to downward displacement of the shutter. In such cases, it will be noted that that thestrips 9 project from the inner faces of the arms 11 of the U, y
In the case of the metal shape 5, it will be noted that the male part 13 is formed by the end and in the extension of a central web 19 provided with pairs of longitudinal flanges 21 and 23 on either side, respectively, of the said central web 19 projecting from the latter in such a way that a portion of their edges constitutes shoulders 25-25 against which corresponding edges 27-27 of side member 3 come to butt to thus ensure that the side members 3 and 5 stand at right angles.
The downward direction mentioned above is that during which the joint may be dislocated. However, when the shutter l is displaced in the opposite direction, it is obviously not subjected to forces tending to dislocate it.
As will be seen from FIG. 3, the flanges 21 and the inner face of the central web 19 define a channel adapted to receive a glass pane 29 provided along its periphery with a water-proofing strip 3 1 of known type. Similarly, FIG. 4 shows that the channel 11 is intended to likewise receive the glass pane 29 provided with the strip 31 which comes to butt against the strips 9. When the four joints of the shutter are assembled with the glass pane and with the waterproofing strip 31 in position, friction alone is sufficient to hold them in position transversally of the direction A whereas the strips 9 in the grooves 15 eliminate the possibility that the joints be dislocated, as previously explained.
The flanges 23 in cooperation with the inner face of the central web 19 define a channel 33 that can be mounted on a slidebar (not shown) serving to guide the shutter 1 when being displaced. Similarly, the side cheeks ll of the side member 3 may extend beyond the bight 17 (FIG. 4) to define a channel 35 that can be applied against a waterproofing strip provided on the corresponding sides of the frame of the window receiving the shutter.
Finally, the side member 3 is provided with a lever 37 controlling sliding of the shutter, such lever being also of a known design.
I claim:
1. A joint interconnecting the ends of two adjacent side members of a shutter movable in either of two opposite directions, one side member extending transverinwardly transversally of the direction A. The joint also 7 comprises a male part 13 formed at the end of the side sally of said directions and the other parallel to said directions, said joint being characterized by the following features:
a. the other side member is a metal shape having a solid elongated central web provided on either side with a pair of longitudinal flanges projecting from said web, the said pairs of flanges respectively defining an outer channel for the reception of a slide 3 bar to guide said shutter and an inner channel; the flanges defining said inner channel terminating short of the end of said web to define transverse shoulders; the flanges defining said outer channel extending beyond said web; said web further having a transverse groove between said transverse shoulders and the end of said central web;
