Definitions

  • the present invention relates to a method for assembling cladding panels of an escalator, a mounting system for such an assembly and an escalator with such a mounting system.
  • An escalator (or escalator) is a means of transport for people to overcome a height distance, in which a plurality of movable individual segments form several steps to transport people over the height distance.
  • escalator designed as a moving walkway, the individual elements do not form a staircase that overcomes a height distance, but rather a flat or inclined surface.
  • escalator is also intended to include moving walks.
  • the US 2004/0257800 A1 discloses translucent cladding panels fixed to a balustrade of a moving walkway or escalator.
  • the cladding panels In order to prevent the risk of injury caused by manual intervention by people in the interior of the escalator with its moving parts, the cladding panels must have a minimum rigidity necessary. According to the EN 115 standard, a gap of currently a maximum of 4 mm is permitted when a force of currently 250 N acts on the cladding panels. It must also be ensured that unauthorized removal of the cladding panels by pulling off the cladding panels is not possible.
  • the present invention relates to a method for assembling cladding panels of an escalator and an escalator with a mounting system for such assembly according to the independent claims.
  • a first cladding panel and a second cladding panel are arranged between a first stabilizing element and a second stabilizing element in such a way that they form a butt joint, the first cladding panel and the second cladding panel resting on the first stabilizing element.
  • at least one first spring is arranged in the area of the butt joint in such a way that it presses the first cladding panel and the second cladding panel onto the first stabilizing element with a first end and is supported on the second stabilizing element with a second end.
  • the invention is based on the knowledge that the resilient mounting of the cladding panels can reliably prevent the formation of gaps with gap sizes, in particular gap sizes larger than 4 mm. This increases the operational safety of the escalator.
  • At least one second spring is arranged between the first stabilizing element and the second stabilizing element in an area outside the butt joint.
  • the area outside the abutment area can be, for example, edge sections of the cladding panels, so that the at least second spring presses edge sections of the cladding panels onto the first stabilizing element and fixes them.
  • a plurality of springs are arranged at a distance in the main direction of extension of the escalator.
  • the main direction of extension of the escalator extends in the direction of the conveying direction of the escalator. So can a side panel are formed from several cladding panels, which are connected one behind the other on the butt side in the main extension direction of the escalator, and whose edge sections are pressed by the at least second spring onto the first stabilizing element and the second stabilizing element.
  • At least one stiffening profile extending along the butt joint is provided, and at least the first spring is arranged between the stiffening profile and the second stabilizing element at the second position.
  • the stiffening profile achieves an improved transmission of the spring force of the at least first spring to the butt joint along its entire length.
  • At least the first spring presses the stiffening profile in the direction of the first cladding panel and the second cladding panel. This reliably prevents one of the two cladding panels from being pressed in towards the interior of the escalator and the resulting gap formation.
  • the interior of the escalator is the space that is only accessible after the cladding panels have been removed.
  • the first cladding panel and the second cladding panel are cohesively connected to one another in the area of the butt joint. This means that no additional connecting or fastening means are required. This simplifies assembly and reduces logistics costs.
  • the first cladding panel and the second cladding panel are connected by a connecting element bridging the butt joint materially connected to each other. This provides a particularly resilient connection between the first and second cladding panels, making it even more difficult to press in one of the two cladding panels.
  • the first cladding panel and the second cladding panel are bonded to one another using a double-sided adhesive tape.
  • This also provides a particularly resilient connection between the first and second cladding panels, making it even more difficult to press in one of the two cladding panels.
  • the first cladding panel and the second cladding panel are cohesively connected to the stiffening profile by means of the double-sided adhesive tape. This reliably prevents one of the two cladding panels from being pulled away from the interior of the escalator, thereby reliably preventing the formation of gaps.
  • the first cladding panel and the second cladding panel are bonded to one another using an adhesive.
  • the adhesive can be a silicone adhesive. This also provides a particularly resilient connection between the first and second cladding panels, making it even more difficult to press in one of the two cladding panels.
  • the first cladding panel and the second cladding panel are cohesively connected to the stiffening profile by means of the adhesive. This reliably prevents one of the two cladding panels from being pulled away from the interior of the escalator, thereby reliably preventing the formation of gaps.
  • a first cladding panel and/or second cladding panel made of Dibond is used.
  • Dibond is a rigid composite material comprising two layers of aluminum thermally bonded to a polyethylene core.
  • the aluminum layers advantageously have a thickness of less than 1 millimeter, in particular a thickness of approximately 0.3 millimeters. This means that cladding panels made from Dibond are lighter than corresponding cladding panels made from aluminum. In this way, a particularly lightweight escalator can be provided.
  • a particular advantage of the use of Dibond panels, i.e. cladding panels made of Dibond, provided according to this advantageous embodiment of the invention, is that these Dibond panels are very light and can therefore be installed in large dimensions, in particular in larger dimensions than, for example, with cladding panels made of aluminum.
  • the disadvantage of the very low rigidity of these Dibond panels, which previously prevented the use of these Dibond panels, is advantageously taken into account by the method proposed according to the invention for assembling cladding panels.
  • it is intended to use a stiffening profile for stiffening in the area where two Dibond panels meet. Through The stiffening profile advantageously prevents the Dibond panels from being pushed inwards.
  • a cohesive connection is then created for connecting the Dibond plates to the stiffening profile, particularly advantageously for connecting the Dibond plates to one another and to the stiffening profile, particularly preferably by using a double-sided adhesive tape.
  • This cohesive connection is particularly advantageous in order to prevent the Dibond panels from being pulled outwards, i.e. away from the stiffening profile. Tests have shown that a double-sided adhesive tape, which is advantageously particularly easy to install, is sufficient to create a long-lasting connection due to the low weight of the Dibond panels.
  • Another advantage of this solution is that a particularly clean butt connection, that is, in particular a butt connection without offset, is achieved. This advantageously creates a particularly aesthetically pleasing escalator paneling that appears at least almost seamless.
  • the stiffening profile is designed as a U-profile.
  • the stiffening profile is therefore made from a readily available material by cutting it to length.
  • the stiffening profile has an insertion section.
  • the insertion section is designed, for example, to be inserted into a receiving opening in the frame of the escalator. This means that no additional connecting or fastening means are required. This simplifies assembly and reduces logistical effort, since no such connecting or fastening means need to be provided for attaching the stiffening profile to the escalator frame.
  • the escalator frame can be an I or double T-section beam with an upper chord and a lower chord.
  • an escalator 2 for overcoming a height difference is shown schematically as a preferred embodiment of an escalator according to the invention. Deviating from the in Figure 1 In the embodiment shown, the escalator 2 can also be designed as a horizontal moving walkway that does not overcome any height difference, or can also be designed as an oblique or inclined moving walkway.
  • the escalator 2 has a main extension direction H, which extends in or parallel to the conveying direction of the escalator 2.
  • the escalator 2 has a side cladding which is formed from a plurality of cladding panels, of which, for reasons of clarity, only a first cladding panel is designated by the reference number 4 and a second cladding panel is designated by the reference number 6.
  • the first cladding panel 4 and the second cladding panel 6 are made of Dibond, for example.
  • Dibond is a rigid composite material that consists of two approximately 0.3 millimeter thick aluminum layers that have been thermally bonded to a polyethylene core. Therefore Dibond is lighter than aluminum.
  • the cladding can also be constructed or provided from cladding panels made of other materials.
  • the first cladding panel 4 and the second cladding panel 6 form a butt joint 8 with one another.
  • the butt joint 8 runs along the section line AA.
  • the cutting line B - B runs parallel to the cutting line A - A, ie outside the area of the butt joint 8.
  • Figure 2 shows a section along the section line A - A in Figure 1 , i.e. along the butt joint 8.
  • both the first cladding panel 4 and the second cladding panel 6 are provided with their reference numbers, although in the view in Figure 2 the first cladding panel 4 covers the second cladding panel 6.
  • the cladding formed by the first cladding panel 4 and the second cladding panel 6 delimits an interior 12 of the escalator 2, in which, for example, movable components (not shown) of the escalator 2 are accommodated, from the exterior of the escalator 2.
  • the escalator 2 has a frame 10 in the interior 12, which in the present embodiment includes an upper chord 18 and a lower chord 24 of a second stabilizing element 46, for example an I or double T-profile beam.
  • a second stabilizing element 46 for example an I or double T-profile beam.
  • a stiffening profile 14 is arranged between the upper chord 18 and the lower chord 24 on one side and the first cladding panel 4 and the second cladding panel 6 on the other side.
  • the stiffening profile 14 rests across the butt joint 8 on the first and second cladding panels.
  • an upper spring 16a is arranged between the upper chord 18 and the stiffening profile 14, which is supported with its first end on the upper chord 18 and with its second end on the stiffening profile 14.
  • the stiffening profile 14 is pressed against the first cladding panel 4 and the second cladding panel 6 by the spring force of the upper spring 16a.
  • a lower spring 16b is arranged between the lower chord 24 and the stiffening profile 14, which is supported with its first end on the lower chord 24 and with its second end on the stiffening profile 14.
  • the stiffening profile 14 is pressed against the first cladding panel 4 and the second cladding panel 6 by the spring force of the lower spring 16b.
  • Figure 3 shows a section along the section line B - B in Figure 1 .
  • a first stabilizing element 48 is provided to fix the first cladding panel 4 and the hidden second cladding panel 6.
  • the first stabilization element 48 has two sub-elements 20, 28.
  • the first sub-element 20 is an upper cover strip which is attached to the upper flange 18 (in Figure 3 not explicitly shown).
  • the second sub-element 28 is a lower cover strip which is attached to the lower flange 24 (this attachment is also in Figure 3 not explicitly shown).
  • an upper spring 22a is arranged between the upper chord 18 and the first sub-element 20, the first end of which is on the upper chord 18 and the second end of which is on the first cladding panel 4 and the second cladding panel 6 is supported.
  • the first cladding panel 4 and the second cladding panel 6 are pressed against a stop of the first sub-element 20 by the spring force of the upper spring 22a.
  • a lower spring 22b is arranged, which is connected to it first end on the lower flange 24 and is supported with its second end on the first cladding panel 4 and the second cladding panel 6.
  • the first cladding panel 4 and the second cladding panel 6 are also pressed against a stop of the second sub-element 28 by the spring force of the lower spring 22b.
  • a plurality of springs 22a, 22b are arranged spaced apart in the main extension direction H of the escalator 2 between the first stabilizing element 48 and the second stabilizing element 46 in an area outside the butt joint 8.
  • the distance between adjacent springs can e.g. B. 100 mm - 150 mm.
  • the area outside the butt joint 8 is, for example, upper or lower edge sections of the cladding panels 4, 6, so that edge sections of the cladding panels 4, 6 are pressed against the first stabilizing element 48 by the springs 22a, 22b and are thus fixed.
  • the second sub-element 28 can have a receptacle into which a section of a bottom spring (not shown) can be inserted.
  • the bottom spring can be supported with its first section on the second sub-element 28 and with its second section on a lower cladding panel (not shown) of the cladding of the escalator 2.
  • the lower cladding panel can also be made of Dibond. Deviating from this, a lower cladding panel made of a different material can also be used.
  • Figure 4 shows a further sectional view along a line running at right angles to the section line A - A, in Figure 2 shown section line C - C.
  • the method described below for assembling cladding panels 4, 6 is based on the formation of a side cladding of the escalator 2 as in the Figures 2 and 3 shown explained.
  • the method for assembling an escalator 2 is also suitable for assembling lower cladding panels.
  • Lower cladding panels are designed to cover the bottom of the escalator 2.
  • first cladding panel 4 and the second cladding panel 6 are arranged adjacent to one another at the butt joint 8.
  • the first cladding panel is used for this purpose 4 and the second cladding panel 6 as in Figure 3 shown fixed with the help of the upper spring 22a and the lower spring 22b.
  • a connecting element 32 is connected to the first cladding panel 4 and the second cladding panel 6 in a cohesive manner by gluing, bridging the butt joint 8.
  • the connecting element 32 is therefore arranged in the interior 12 of the escalator 2. This reliably prevents one of the two cladding panels 4, 6 from being pulled off in the direction of arrow P.
  • the stiffening profile 14 which is U-shaped according to the present embodiment, is arranged between the second stabilizing element 46 and the connecting element 32.
  • the stiffening profile 14, like the connecting element 32, is arranged bridging the butt joint 8. Furthermore, the stiffening profile 14 extends along the butt joint 8, i.e. along the section line A - A (see Figure 1 ). In this way, an optimal transmission of the spring force of the springs 16a, 16b to the butt joint 8 is achieved along its entire width and length.
  • the springs 16a, 16b are inserted into the stiffening profile 14.
  • the springs 16a, 16b are supported with a first end on the stiffening profile 14 and a second end on the framework 10.
  • their spring force acts on the stiffening profile 14 and thus also the first cladding panel 4 and the second cladding panel 6 in the area of the butt joint 8 in the direction of arrow P. Since the stiffening profile 14 extends along the entire length and width of the butt joint 8, an optimal transmission of the spring force of the springs 16a, 16b to the butt joint 8 is achieved. This reliably prevents one of the two cladding panels 4, 6 from being pressed in.
  • the stiffening profile 14 has a width in the direction of the main extension direction H of the escalator 2, which is dimensioned such that the stiffening profile 14 covers the abutting edge regions of the cladding panels 4, 6.
  • the width of the stiffening profile 14 can be dimensioned such that it covers 3% to 20%, in particular 10% to 20%, of the area of the respective cladding panels 4, 6.
  • a double-sided adhesive tape 34 can be used, which bridges the butt joint 8 and thus connects the first cladding panel 4 and the second cladding panel 6 to one another in a materially bonded manner. Furthermore, the double-sided adhesive tape 34 connects the two cladding panels 4, 6 in a cohesive manner with the stiffening profile 14. The double-sided adhesive tape 34 is therefore arranged in the interior 12 of the escalator 2. This also reliably prevents one of the two cladding panels 4, 6 from being pushed in or pulled off.
  • Figure 5 shows another representation of the in Figure 4 illustrated connecting element 32.
  • the connecting element 32 is designed as a row of teeth having a plurality of teeth 44.
  • the design as a row of teeth provides a particularly lightweight and easy-to-process connecting element 32, which also takes up particularly little space inside 12 of the escalator 2.
  • Figure 6 shows another embodiment that differs from that in Figure 4
  • the embodiment shown differs in that instead of the connecting element 32 or the double-sided adhesive tape 34, an adhesive 36 is used to bridge the butt joint 8 and thus to connect the first cladding panel 4 and the second cladding panel 6 to one another in a materially bonded manner.
  • the adhesive 36 connects the two cladding panels 4, 6 in a materially bonded manner to the stiffening profile 14 (in Figure 6 not explicitly shown).
  • the adhesive 36 is a silicone adhesive. This reliably prevents one of the two cladding panels 4, 6 from being pressed in or pulled off.
  • the Figures 7 and 8th show further views of the stiffening profile 14.
  • the stiffening profile 14 with the U-shaped cross section has a base section 38 and two end sections 40 adjoining the base section 38, each of which forms a receptacle for the springs 16a, 16b. Furthermore, they show Figures 7 and 8th that the stiffening profile 14 has an insertion section 42 at each of its distal ends, which are designed for insertion into receptacles of the framework 10 in order to fix the stiffening profile 14.
  • the assembly method provides an escalator 2 in which the risk of injury due to manual intervention by people in the interior 12 of the escalator 2 is prevented.
  • the EN115 standard is met, according to which a gap of currently a maximum of 4 mm is permitted when a force of currently 250 N acts on the cladding panels 4, 6. Furthermore, it is not possible to remove the cladding panels 4, 6 by pulling them off.
  • the escalator 2 has an aesthetic appearance because invisible butt joints are formed between the cladding panels 4, 6.
  • various cladding panel materials can be used to cover the escalator 2 in order to give the escalator 2 an aesthetic appearance.
