[0040] FIG. 1 shows diagrammatically a part of a preferred embodiment of a transporting apparatus according to the invention, designated 100. In this example, the transporting apparatus 100 is configured as an escalator.

[0041] The escalator 100 has a truss 101. This truss 101 is for example formed as a lattice structure from a plurality of e.g. longitudinally oriented, vertical and/or diagonal beams.

[0042] This truss 101 may contain various elements of the escalator 100 which are not shown in FIG. 1 for the sake of clarity. For example, a conveyor belt in the form of a stepped belt, and elements for its movement, may be arranged in the truss 101.

[0043] The escalator 100 may contain further elements which are not shown in FIG. 1 for the sake of clarity: for example handrails, drives for moving the handrails, shafts, gears, gearwheels, chains, further rails etc.

[0044] The truss 101 has a first or upper end 110, and a second or lower end 120. Elements are provided at the ends 110 and 120 for fitting the escalator 100 on a building. FIG. 1 shows a first bearing 102 and a second bearing 103 of this building. These bearings are in particular connected fixedly to the bearing, or are formed as part of the building. The escalator 100 is fitted on these bearings 102 and 103 and thus on the building. The bearings 102 and 103 are formed for example from concrete.

[0045] A first or upper support angle 111 is fitted on the truss 101 at the upper end 110. This first support angle 111 is fitted on the first bearing 102 via a fixed bearing 112. A second or lower support angle 121 is fitted at the second end 120 of the truss 101. This second support angle 121 is fitted on the second bearing 103 via a floating bearing 122.

[0046] The ends 110 and 120 are shown in more detail in FIGS. 2 to 7, and are explained below with reference to these figures. Identical reference symbols in FIGS. 1 to 7 designate the same or similar elements.

[0047] The upper end 110 of the truss 101 is shown diagrammatically in a perspective view in FIGS. 2 and 3, and in a diagrammatic top view in FIG. 4. The first support angle 111 may be fixedly connected to the truss 101, and the support angle 111 and the truss 101 may form a common structural unit. The first support angle 111 and the truss 101 may however also be separate elements, wherein the first support angle 111 may for example be bolted to the truss 101.

[0048] For the fixed bearing 112, the first support angle 111 has a hole 113. A first fixing element 114 is introduced into this hole 113, or the first fixing element 114 passes through the hole 113. In this example, the first fixing element 114 is formed as a pin or peg. The pin 114 is connected by force fit to the first bearing 102. A first locking element 115 is fitted on the pin 114. The first locking element 115 is in particular formed as a first disc which is for example screwed onto the pin 114.

[0049] The diameter of the hole 113 substantially corresponds to the diameter of the pin 114. For example, the hole 113 may be larger by maximum 0.5% than the diameter of the pin 114. The pin 114 can thus pass easily through the hole 113.

[0050] As depicted in FIGS. 2 to 4, the first support angle 111 lies on the elements 116 which are fixedly connected to the first bearing 102. These elements 116 are for example formed as threaded bolts which are screwed into the first bearing 102.

[0051] The fixed bearing 112 prevents a translational movement of the first support angle 111 relative to the bearing 102. A rotational movement of the first support angle 111 and hence of the truss 101 about the pin 114 is however possible within the limits defined e.g. by the first bearing 102.

[0052] The second lower end 120 of the truss 101 is shown diagrammatically in a perspective view in FIGS. 5 and 6, and in a diagrammatic top view in FIG. 7. In the same way as the first support angle 111, the second support angle 121 may also be fixedly connected to the truss 101 or fastened, for example bolted, thereto.

[0053] For the floating bearing 122, the second support angle 121 has a slot 123. The main extension direction of the slot 123 corresponds to the main extension direction of the escalator 100.

[0054] A second fixing element 124 in the form of a pin passes through the slot 123. The pin 124 is connected by force fit to the second bearing 103. A second locking element 125 in the form of a disc is fitted, for example screwed, onto the pin 124.

[0055] The width of the slot 123 substantially corresponds to the diameter of the pin 124. For example, the width of the slot 123 may be larger by maximum 0.5% than the diameter of the pin 124. The pin 124 can thus easily pass through the slot 123.

[0056] In this example, the length of the slot 123 is 140 mm longer than the diameter of the pin 124. Thus a translational movement of the second support angle 121 relative to the second bearing 103 is possible in a range of 70 mm in the main extension direction of the escalator 100.

[0057] The second support angle 121 also lies on elements 126 in the form of threaded bolts which are fixedly connected to the second bearing 103.

[0058] The floating bearing 122 allows a translational movement of the second support angle 121 in a range of 70 mm in the main extension direction of the escalator 100. Furthermore, a rotational movement of the second support angle 121 and hence the truss 101 about the pin 124 is possible.

[0059] In the event of a natural disaster, for example an earthquake, forces caused by the natural disaster and acting on the escalator 100 may be compensated within certain limits. Since the escalator 100 is not rigidly fastened to the building, a compression, an extension, or a rotational or shear movement of the building, in particular e.g. of the bearings 102 and 103 relative to each other, is ideally not transmitted to the truss 101. Thus, up to a certain degree of severity of the natural disaster, stresses in the truss 101 from the forces occurring, and the resulting damage, can be prevented. In particular, a breakage of individual beams of the truss 101 can be prevented more effectively than with conventional escalators.

[0060] For example, on a natural disaster, the bearings 102 and 103 may move apart or towards each other in the main extension direction of the escalator 100. By the suppression of translational movements of the first support angle 111, in such a case this is secured and the escalator 100 executes the similar movement of the first bearing 102. Because of the possible translational movement of the second support angle 121 in the main extension direction, the escalator 100 can move relative to the second bearing 103.

[0061] For example, on a natural disaster, the bearings 102 and 103 can also rotate about a common rotation axis or about different rotational axes perpendicular to the main extension direction of the escalator. Due to the possible rotation of the support angles 111 and 121 about the respective pins 114 and 124, in such a case the escalator 100 can rotate in the same way as the bearings 102 and 103 about the corresponding rotation axes perpendicular to the main extension direction.
