Cantilevered floating gate

The innovation concerns a cantilevered sliding gate with a guide rail with a substantially U-profile, which runs on rollers anchored to the ground and engaging laterally into the guide rail, a hollow profile lower belt attached to the top of the guide rail parallel to it, and an upper belt, with the door leaf attached between the lower belt and the upper belt.

The innovation is based on the task of creating a sliding gate, which in the rule has a length of up to

6 m or more, in such a way that sufficient torsional strength and sufficient rigidity against thermally induced buckling of the sliding gate can be achieved using the simplest means.

To solve this problem, the innovation provides that the guide rail and the bottom flange are made as a single piece from a pressed-in combination profile.

According to a further innovation, additional reinforcement tires are molded onto the combination profile to further increase strength.

The self-supporting sliding gate 1 shown in the drawing consists of a door leaf 4 fastened between an upper chord 2 and a lower chord 3. The lower chord 3 is extruded as a hollow profile in one piece with a combination profile and a guide rail 5, preferably made of aluminum. The guide rail essentially has the shape of a U-profile with an angled base part 6 and upper and lower legs 7 and 8. The outer edges of the legs 7 and 8 are connected to stiffening strips 9 and 10, which are bent inwards at an obtuse angle and are also extruded in one piece with the combination profile. The inner edge of the upper strip 9 is in turn connected to a stiffening strip 11, the width of which preferably corresponds at least to the width of the legs 7 and 8 and which runs parallel to the legs of the U-profile. An angle profile 12 can be attached to the upper side of the strip il.

Further longitudinal stiffening strips 15 are formed on the lower outside of the U-profile guide rail 5, as well as on the inside

the hollow-fibre bottom belts 3.

Rollers 13 _protrude laterally into the space defined by the U-profile, only one of which is shown in the drawing. The individual rollers 13

are attached to a roller block 14 anchored in the ground in such a way that the rollers can rotate about horizontal axes.

Guide posts 15 attached to both sides of the sliding gate 1 carry support rollers 1», which preferably rest laterally against the upper chord 2.
