Description

The invention relates to a sliding gate with the features of the preamble of claim 1. Sliding gates with a one-piece or sectioned leaf have long been known for closing off garages. Their lower guide usually consists of a U-profile with the legs open upwards into which guide rollers mounted on the leaf engage.

Another well-known design uses a web protruding from the road surface as the lower guide. Support point guides are also common, which only guide the wing purely inside or outside.

It often happens that the familiar sliding doors freeze in the interspace. This effect is caused by various circumstances.

As a rule, the snow brought by the vehicles melts in the garage. The meltwater flows due to the slope to the gate, penetrates the guide elements and forms ice crusts there.

It is also possible that rainwater penetrating from the outside will cause the guide to freeze.* This is particularly noticeable in early _or late winter with gates that are installed on the winter side. The rainwater penetrating during the day freezes at night and forms ice bridges between the stationary and moving parts of the gate.

Another problem is caused by snow being introduced when driving over the guide with car tires.

There are two methods known to prevent freezing: spreading de-icing agents and electrically heating the lower guide. De-icing agents are questionable for environmental reasons; they also lead to corrosion damage to the steel parts. The electrical de-icing devices are relatively expensive, consume energy and require maintenance.

The invention is therefore based on the task of designing the lower guide of sliding gates in such a way that even in winter the vulnerability to the danger

of freezing the feet*

This object is achieved according to the invention in that the guide consists of guide walls and walls running parallel to these at a distance. The walls drain the meltwater. Ice crusts forming there do not hinder the guide elements which are guided along the dry guideways.

The meltwater is drained away via relatively deep channels, which are preferably arranged on both sides of the tracks.

According to the invention, such a guide consists of several parallel profiles that can be varied depending on the installation. For example, it is possible to adapt the guide without thresholds and with thick-walled profiles to allow forklifts to drive over it. In a preferred arrangement, the guideways are formed from the upright leg of a T-profile, with the flange resting on the roadway or anchored in it. The leg of the T-profile has a particularly high bending strength and can therefore withstand high tangential forces that are introduced at its drive-over edge by braking or accelerating vehicles. Y-shaped profiles can be easily attached to the flange of the T-profile directly or via connecting parts that form the walls and the channels at the same time.

Instead of the T-profile, a U-profile can also be used. Here, the inner sides of the legs form the guideways and profiles arranged next to them form the walls and gutters. The heights of the crossing edges of the U-profile are advantageously dimensioned lower than those of the Y-edges. The edges of the walls act as scraper edges and the legs of the U-profile are not subjected to tangential forces.

; According to the invention, walls with different heights are also provided. For example, the override edge of the part forming the outer wall can be designed so that it projects beyond the lower edge of the gate leaf and forms a cover with it.

^ If a good seal on the door is important and driving rain from outside is not to be expected, then a sealing strip can be attached to the door leaf, the edge of which runs along the outside edge.

The installation of the finished floor in the garage at the correct height is made easier by the fact that the drive-over edge of the inside wall determines the height of the floor. The floor is thus flush with the edge; there is no edge where water can collect.

The guide must be firmly anchored in the track. This is done during installation on the subfloor using dowels and, according to the invention, particularly by a contour of the guide that undercuts the floor.

In the crossing area, the parts of the guide must be dimensioned to be heavy enough to withstand the forces to be absorbed. In the parking or curved area, where freezing problems do not occur, only low demands are placed on the lower guide. It is therefore intended that the guide outside the crossing area consists of only one profile, such as the web arch and the Y-shaped web.

In terms of resistance to dirt and slush, a pair of rollers guided by a web is superior to a roller running in a U-profile. In order to achieve good cornering properties of the rollers guided by a web, they are designed with axes arranged offset in the door plane.

In the following, embodiments of the invention are explained in more detail with reference to drawings. They show:

Figure 1 shows a cross-section of the embodiment with web guide. The guide tracks 11 and 12, along which the guide rollers 61 and 62 run, are formed by the leg of the T-profile 18. Angle profiles are attached to the flange of the T-profile 18, creating walls 21 and 22 and channels 23. The Y-walls 21 and 22 are dimensioned so that there is sufficient distance from the rollers 61 and 62 and ice crusts 8 that form there do not impair the mobility of the gate leaf 4. Meltwater flowing over the inside floor surface passes over the wall 21 into the channel 23 and flows off to the side. The crossing edges 25 and 26 of the walls and those of the profile 18 are at the same height in this example, which avoids having to drive over a threshold. The contours 13 of the flange undercut the concrete floor and provide additional anchoring of the guide.

The embodiment shown in Figure 2 differs from that in Figure 1 in that the wall 22 is higher on the outside. This wall covers the lower edge of the door leaf 4, but leaves the air passage cross-section required for ventilation of garages. If this air access is not desired, which occurs when the room is used for other purposes, the cross-section can be narrowed considerably with a sealing strip 5 attached to the door leaf 4. In this case, it is assumed that no driving rain can reach the door from the outside. Figure 2 also shows an alternative way of attaching the angle profiles to the T-profile using connecting parts 24. This arrangement can be advantageous if specified threshold heights are to be maintained using commercially available profiles. Here, too, the flat contours 13 are created again.

Figure 3 shows a solution in which the guideways 11 and 12 are formed by the inner sides of the legs of a U-profile. Angle profiles are attached to both sides of the U-profile, which form the walls 21 and 22 and the channels 23. The crossing edges of the U-profile 15 are designed to be deeper. The scraping effect therefore occurs on the higher crossing edges 25 and 26; in addition, the edges 15 remain free from tangential forces.

Figure 4 shows a plan view of the entire lower guide. In the overpass area, an example of the multi-profile solid design with the walls 21 and 22 and the guide tracks 11 and 12 can be seen. In the non-driveable arch 1? and in the parking area (open position of the gate), the construction effort of the guide is reduced to the web arch 17 or the angle web 16.

Figure 5 demonstrates the variety of design options of the guide within the framework of the inventive concept. In Figure 5a, the profiles 21 and 22 forming the walls are not directly connected to the part forming the guideways 11 and 12, but are anchored directly in the concrete. In this case, the concrete takes on the role of the connecting parts 24. In Figure 5b, the guide consists of 2 parallel IT profiles, the inside of the legs of which take on the roles of the walls 21 and 22 and the guideways 11 and 12. In Figure 5c, only one channel 23 is provided on the inside; the outside is omitted because, for example, a canopy is present.

In Figure 5d, Z-profiles are used * which are connected by welding points to the profile forming the conductor tracks.
