Disclosure of the invention

According to the invention, a transport device and a method for installing a transport device in a building are proposed with the features of the independent claims. Advantageous refinements are the subject matter of the subclaims and the description below.

The conveying device is designed in particular as an escalator or as a moving walkway, further in particular as a passenger conveying device. A first support bracket is attached to a first end of a carrier or frame of the conveying device. A second support bracket is attached to a second end of the beam. The support brackets are intended in particular to support the support on a building.

The first support bracket is attached to the building via a fixed bearing. The first support bracket has a hole. A first fastener attached to the building penetrates the hole. The second support bracket is attached to the building via a floating bearing. The second support bracket has an elongated hole. A second fastening element fastened to the building penetrates the elongated hole. The main direction of extent of the elongated hole runs in particular parallel to the main direction of extent of the conveying device.

In particular, an appropriate support is provided on the building, to which the respective support bracket is attached. These supports can be made of concrete, hardwood and / or hard rubber, for example. The first or the second fastening element is in particular fastened to the respective support.

The conveying device has, in particular, a conveying belt, in particular an endlessly revolving, movable conveying belt. In the case of an escalator, the conveyor belt is designed, in particular, as a step belt and, in the case of a moving walk, in particular as a conveyor belt. The conveyor may have other useful elements, for example a balustrade, handrails, drives for moving the conveyor belt and handrails, shafts, gears, gears, chains, rails, etc.

In particular, the carrier represents a carrier structure in which different elements of the conveyor device are arranged, for example the conveyor belt and elements for moving it. The carrier is designed, for example, as a framework structure and is composed of a large number of longitudinal, vertical and / or diagonal struts or beams, which can be made of metal or steel.

The first support bracket is mounted on the building via the fixed bearing in such a way that a translational movement of the first support bracket is prevented in all three spatial directions and that a rotary movement, in particular around a vertical axis or around a main direction of extent of the building, is enabled.

The second support bracket is in particular mounted on the building via the floating bearing in such a way that a translational movement of the second support bracket in one of the three spatial directions is made possible, at least to a certain extent. In particular, a translational movement along a main direction of extent of the conveying device or along a direction of movement of the conveyor belt is made possible via the floating bearing.

Translational movements perpendicular to this main direction of extent of the conveying device are in particular prevented. The floating bearing also enables, in particular, a rotational movement around the main direction of extent of the building.

The conveyor is secured against damage caused by natural disasters such as earthquakes or hurricanes. The transport device is particularly suitable for use in buildings in earthquake-prone areas or in areas with strong seismic activities and is protected against damage from earthquakes or seismic activities. In the event of such natural disasters, high forces, loads and accelerations can act on the conveying device. The fixed bearing ensures that the transport device is not undesirably set in translatory motion by the forces that occur during natural disasters. Since both bearings enable rotational movements at least around the main direction of extent of the building and since the floating bearing enables translational movement in one of the three spatial directions, the conveying device can yield to the forces that occur at least to a certain extent and compensate for them. It is thus prevented that the forces occurring in the conveying device, in particular in its carrier, cause tension and that the conveying device, in particular its carrier, is damaged. In particular, breaking of individual struts or beams of the carrier can be prevented. Furthermore, it is prevented that the conveyor device can fall down in the case of a natural disaster in the building.

According to an advantageous embodiment, a first securing element is attached to the first fastening element. Alternatively or additionally, a second securing element is attached to the second fastening element. By means of a securing element of this type, the respective support bracket is secured in particular against displacement in the vertical direction. In particular, can thus a translational movement of the transport device in the vertical direction or in the main direction of extent of the building can be prevented. The securing elements are in particular each attached to an upper end of the respective fastening element, which protrudes from the respective support bracket.

In particular, the first or second securing element is made from the same material as the respective fastening element. The first or second securing element can prevent the transport device from "jumping" out of the support angles or being moved out of these by the forces occurring during natural disasters and thus falling down in the building, particularly in the event of natural disasters.

The first securing element and / or the second securing element are preferably each designed as a washer, for example a round, square or rectangular washer, a nut, a securing ring or a split pin. According to a preferred embodiment, the first securing element is designed as a first disk, the width of which is greater than the width of the hole of the first support bracket. Alternatively or additionally, the second securing element is preferably designed as a second disk, the width of which is greater than the width of the elongated hole.

The first securing element and the first fastening element and / or the second securing element and the second fastening element preferably each form a structural unit. The respective securing element and the respective fastening element are manufactured in particular as one component.

The respective securing element and the respective fastening element can preferably also be designed as separate elements. The first securing element is preferably applied to the first fastening element and / or the second securing element on the second fastening element. For example, the respective securing element can be screwed or slipped onto the respective fastening element. In particular, the respective securing element can be screwed onto the respective fastening element in the form of a nut or slipped on in the form of a plate.

The first fastening element and / or the second fastening element is advantageously designed in each case as a pin, pin or bolt and / or threaded bolt. In particular, a thread or dowel can be provided in the support of the building in order to fasten the fastening element designed as a threaded bolt. The fastening element can also be fastened to the support of the building with a force fit.

Preferably, the first fastening element and the second fastening element are essentially cylindrical. As an alternative or in addition, the hole of the first support bracket is preferably designed to be essentially circular. The hole of the first support bracket preferably has the same diameter as the first fastening element or essentially the same diameter as the first fastening element. In particular, the diameter of the hole is only insignificantly larger than the diameter of the first fastening element, for example a maximum of 0.25%, 0.5%, 1% or 5% larger than the diameter of the first fastening element. The first fastening element can thus be inserted through the hole in a simple manner.

The width of the elongated hole preferably corresponds to the diameter of the second fastening element or essentially the diameter of the second fastening element. In particular, the width of the elongated hole is only insignificantly larger than the diameter of the second fastening element, for example a maximum of 0.25%, 0.5%, 1% or 5% larger than the diameter of the second fastening element. The second fastening element can thus also be inserted through the elongated hole in a simple manner.

The length of the elongated hole is preferably between 100 mm and 350 mm longer than the diameter of the second fastening element. The length of the elongated hole is thus dimensioned such that a translational movement of the second support bracket is made possible in a range between ± 50 mm and ± 175mm, in particular if the second fastening element is arranged essentially in the center of the elongated hole, based on the length of the elongated hole . The length of the elongated hole is particularly preferably between 140 mm and 280 mm longer than the diameter of the second fastening element. This enables a translational movement of the second support bracket in a range between ± 70 mm and ± 140 mm, in particular with an essentially central arrangement of the second fastening element in the elongated hole, based on its length.

Advantageously, the first support bracket is attached to an upper end of the support and the second support bracket is attached to a lower end of the support. The conveying device can thus be attached via the fixed bearing in particular to an upper floor of the building and via the floating bearing in particular to a lower floor of the building.

In addition to the transport device, the invention also relates to a method for installing a transport device in a building. Refinements of this method according to the invention emerge from the above description of the conveying device according to the invention in an analogous manner.

To install the transport device, it is arranged in the desired position in the building, for example between two floors. The first fastener is through the hole in the first Inserted support bracket and attached to the building and the second fastening element is inserted through the elongated hole in the second support bracket and attached to the building.

Preferably, the first support bracket is attached to an upper floor of the building via the fixed bearing and the second support bracket is attached to a lower floor of the building via the floating bearing.

Further advantages and embodiments of the invention emerge from the description and the accompanying drawing.

It goes without saying that the features mentioned above and those yet to be explained below can be used not only in the respectively specified combination, but also in other combinations or on their own, without departing from the scope of the present claims.

The invention is shown schematically in the drawing using an exemplary embodiment and is described below with reference to the drawing.

In Figure 1 a part of a preferred embodiment of a conveying device according to the invention is shown schematically and denoted by 100. In this example, the conveying device 100 is designed as an escalator.

The escalator 100 has a carrier 101. This carrier 101 is designed, for example, as a truss construction from a multiplicity of, for example, longitudinal, vertical and / or diagonal struts.

Various elements of the escalator 100 can be arranged in this carrier 101, which for the sake of clarity are shown in FIG Figure 1 not shown are. For example, a conveyor belt in the form of a step belt and elements for moving it can be arranged in the carrier 101.

The escalator 100 can also have further elements, which are shown in FIG Figure 1 for the sake of clarity are also not shown, for example handrails, drives for moving the handrails, shafts, gears, gears, chains, other rails, etc.

The carrier 101 has a first or upper end 110 and a second or lower end 120. Elements are provided at the ends 110 and 120 in order to attach the escalator 100 to a building. In Figure 1 a first support 102 and a second support 103 of this building are shown. These supports are in particular firmly connected to the building or are designed as part of the building. The escalator 100 is attached to these supports 102 and 103 and thus to the building. The supports 102 and 103 are formed, for example, from concrete.

A first or upper support bracket 111 is attached to the carrier 101 at the upper end 110. This first support bracket 111 is attached to the first support 102 via a fixed bearing 112. A second or lower support bracket 121 is attached to the second end 120 of the carrier 101. This second support bracket 121 is attached to the second support 103 via a floating bearing 122.

The ends 110 and 120 are in the Figures 2 to 7 shown in more detail and are explained below with reference to these figures. Identical reference numbers in the Figures 1 to 7 denote identical or structurally identical elements.

The upper end 110 of the carrier 101 is in the Figures 2 and 3 each shown schematically in a perspective view and in Figure 4 in a schematic top view. The first support bracket 111 can be firmly connected to the support 101, support bracket 111 and support 101 can form a common structural unit. On the other hand, the first support bracket 111 and the carrier 101 can also be separate components; the first support bracket 111 can be screwed to the carrier 101, for example.

The first support bracket 111 has a hole 113 for the fixed bearing 112. A first fastening element 114 is inserted into this hole 113 or the first fastening element 114 penetrates the hole 113. In this example, the first fastening element 114 is designed as a pin. The pin 114 is non-positively connected to the first support 102. A first securing element 115 is attached to the pin 114. The first securing element 115 is designed in particular as a first disk which is screwed onto the pin 114, for example.

The diameter of the hole 113 essentially corresponds to the diameter of the pin 114. For example, the hole 113 can be a maximum of 0.5% larger than the diameter of the pin 114. The pin 114 can thus be easily inserted through the hole 113.

As in the Figures 2 to 4 As shown, the first support bracket 111 rests on elements 116 which are firmly connected to the first support 102. These elements 116 are designed, for example, as threaded bolts which are screwed into the first support 102.

The fixed bearing 112 prevents a translational movement of the first support bracket 111 with respect to the support 102. However, a rotational movement of the first support bracket 111 and thus of the carrier 101 about the pin 114 is possible within the limits defined, for example, by the first support 102

The second, lower end 120 of the carrier 101 is in the Figures 5 and 6th each shown schematically in a perspective view and in Figure 7 in a schematic plan view. Analogously to the first support bracket 111, the second support bracket 121 can also be firmly connected to the carrier 101 or fastened to it, for example screwed on.

The second support bracket 121 has an elongated hole 123 for the floating bearing 122. The main direction of extent of the elongated hole 123 corresponds to the main direction of extent of the escalator 100.

A second fastening element 124 in the form of a pin penetrates the elongated hole 123. The pin 124 is connected to the second support 103 with a force fit. A second securing element 125 in the form of a washer is applied, for example screwed, to the pin 124.

The width of the elongated hole 123 essentially corresponds to the diameter of the pin 124. For example, the width of the elongated hole 123 can be a maximum of 0.5% greater than the diameter of the pin 124. The pin 124 can thus be easily inserted through the elongated hole 123.

In this example, the length of the elongated hole 123 is 140 mm longer than the diameter of the pin 124. This enables a translational movement of the second support bracket 121 relative to the second support 103 in a range between ± 70 mm in the direction of the main direction of extension of the escalator 100 .

The second support bracket 121 also rests on elements 126 in the form of threaded bolts, which are firmly connected to the second support 103.

The floating bearing 122 causes a translational movement of the second support bracket 121 in the direction of the main direction of extent of the escalator 100 in a range between ± 70 mm. Furthermore, a rotational movement of the second support bracket 121 and thus of the carrier 101 around the pin 124 is possible.

In the event of a natural disaster, for example an earthquake, forces that occur as a result of the natural disaster and act on escalator 100 can be compensated within certain limits. Since the escalator 100 is not rigidly fastened in the building, compression, stretching or twisting or shearing movements of the building, in particular e.g. the supports 102 and 103 relative to one another, are ideally not transmitted to the carrier 101. It is thus possible, up to a certain degree of severity of the natural disaster, to prevent the forces occurring in the carrier 101 from creating tension and from being damaged. In particular, breaking of individual struts of the carrier 101 can be prevented better than in the case of conventional escalators.

For example, in the event of a natural disaster, the supports 102 and 103 can move apart in the main direction of extent of the escalator 100 or move towards one another. By preventing translational movements of the first support bracket 111, this is “held in place” in such a case and the escalator 100 executes the analog movement of the first support 102. Due to the possible translational movement of the second support bracket 121 in the direction of the main direction of extent, the escalator 100 can move relative to the second support 103.

For example, in the event of a natural disaster, the supports 102 and 103 can also rotate about a common axis of rotation or about different axes of rotation perpendicular to the main direction of extent of the escalator. Due to the possible rotation of the support brackets 111 and 121 around the respective pin 114 and 124, the escalator 100 can in such a case rotate around the corresponding axis of rotation perpendicular to the main direction of extent, analogously to the supports 102 and 103.
