Definitions
- the present industrial invention relates to a device, not visible from the outside, for automatically locking drop down shades in slide tracks in such a way as to avoid leaving the fabric exposed to the action of wind.
- BACKGROU N D ART With particular reference to apparatus of this type, excluding traditional systems with a manual stop pin, it may be affirmed that some specifically conceived for their own type of track already exist; however, none can perform its function without com promising the overall aesthetic impact of the device and above all, where the shade is motorized, none can perm it completely automatic remote-controlled operation.
- the device according to the invention which is characterised by being com posed essentially of a suitably configured cylindrical projection integrally joined to the bottom rail of the sliding shade on each of the two tracks, and by an elastically operating stop element disposed inside the track in the bottommost position and, if desired, also in an intermediate position, and which performs a function like that of a railroad "switch".
- 1 indicates the box housing the take-up roller and driving members, 2 the slide tracks, 3 the rail fitted at the bottom extremity of the fabric, not shown here, 4 the switch, 5 the cylindrical projection integrally joined to the extremity of the bottom rail (3) and guided along its path inside the tracks (2) by the switch (4) , 6 fastening screws, 7 centring washers, 4', 4", 4'" guide blades for the cylindrical projection (5), 8 the recess that retains the cylindrical projection (5) and 5' the body of the cylindrical projection, which is fixed to the bottom rail (3) by means of a pin (not shown) passing through the hole 5".
- the device works as follows: during lowering, as the shade is extended , the cylindrical projection (5) descends inside the track (2) and meets the blade (4'), which switches it over from the left to the right side of the track; after it has passed completely over the blade (4") , as the extension phase is terminated and retroaction begins, the cylindrical projection will be forced inside the recess (8) where it will remain locked in place at the end of retraction, thus permitting the fabric to be tensioned.
