Description
Technical Field
The present invention relates to a step for a conveyor system of an escalator. Wherein each step comprises a kick plate, a tread plate, a hinge connecting the kick plate and the tread plate, a traction roller, and at least a first support point and a second support point on each side of the step, wherein at the first support point the step is connected to a step chain. Further, each step is configured to fold via the hinge at least during a turn in the transition region.
The invention further relates to a conveyor system of an escalator and to a method for deflecting steps in a conveyor system.
Background
The escalators known from the prior art comprise a lower transition region at the lower end of the escalator, an upper transition region at the upper end of the escalator, and a transport region between the lower transition region and the upper transition region, wherein the steps of the escalator are diverted in the transition region.
In order to provide sufficient space for the turning of the steps, the escalator requires a pit about 1 meter deep.
In some cases it may be necessary to reduce the size of the pit, for example if there is a particular installation under the escalator, such as a garage or ductwork, which requires space, or if the escalator has to be installed in an existing building and the workload of providing a large pit is very high.
It can also be very interesting to reduce the pit size of escalators used for boarding and disembarking passengers from airplanes, which escalators are usually transported in trucks.
It is therefore desirable to reduce the depth of the pit, particularly the turning radius of the turn of the steps within the pit, particularly for the lower transition zone of an escalator.
EP 1072552 a1 discloses a conveyor system configured to reduce the depth of pits in the lower and upper transition areas of an escalator. Wherein the steps of the conveyor system are folded. In the transition region, the steps are not turned, but are guided in such a way that the treads of the steps are directed upwards at any position. By doing so, the depth of the pit can be reduced, but by guiding the steps in such a way that the treads of the steps always face upwards results in a great increase in the length of the pit.
Disclosure of Invention
It is therefore an object of the present invention to provide a conveying system for an escalator to reduce the pit depth of the escalator without increasing the pit length. Therefore, the construction of the escalator should be simple and not require high costs. In particular, the construction of a typical escalator should not be changed in large part, and therefore a large part of standard components can be used.
In order to solve this problem, a step for a conveyor system of an escalator, a conveyor system of an escalator and a method for diverting a step in a conveyor system are proposed according to the independent claims.
Further, advantageous arrangements of the invention are shown in the dependent claims and in the description and in the drawings.
A solution to this problem provides steps for a conveyor system of an escalator. Wherein each step comprises a riser, a tread, and a hinge connecting the riser and the tread. Further, each step comprises a pull roll, at least a first support point and a second support point on each side of the step. At the first support point, the steps are configured to be connected to a step chain of an escalator. Furthermore, each step is configured to fold via a hinge at least during a turn in the transition area of the escalator.
In particular, the riser of each step comprises at least a curved sliding guide guiding the riser in a predetermined curve when folding the step, in particular when folding the step during a turn.
By bending the slide guide to guide the kick plate in a predetermined curve, collision between adjacent steps is avoided.
In one arrangement, the pull roll is adjusted to accommodate the step at the second support point of the step. Via the pull rolls, the steps are guided to circulate along the pull roll guides of the conveyor system.
In another arrangement, the steps are configured to be connected to the step chain at the first support point in a fixed manner.
In another arrangement, each step includes a third support point. In particular, at the third support point, the steps are configured to be connected to the step chain in a loose manner via the kick plate shaft. This loose connection of the steps with the step chain via the kick plate shaft enables the folding of the steps to be controlled, wherein the kick plate is folded towards the tread plates.
In another arrangement, the support points of the steps are arranged on each side of the steps. In particular, the first support point is arranged at the front edge of the pedal. In particular, the second support point is arranged in the middle region of the pedal. In particular, the third support point is arranged at a riser, wherein the riser is arranged at the rear edge of the tread. In particular, the third support point is arranged on each side of the step and in the middle region of the step width.
In another arrangement, the kick plate shaft comprises a wheel. In particular, the wheels are configured to roll within the curved sliding guides of the kick plate.
Thus, the kick plate shaft is arranged within the curved sliding guide of the kick plate. The wheels adjusted to accommodate the kick plate shaft can achieve frictionless sliding during folding of the steps.
In another arrangement, the kick plate shaft is configured to connect to the step chain via a dedicated fitting. The fitting comprises, in particular, a thread fixed to the step chain and a coupling nut fitted on the thread. The assembly can quickly and conveniently mount and dismount the steps and the step chain.
In another arrangement, the kick plate includes a kick plate reinforcement. In particular, the kick plate reinforcement is arranged at a lower edge of the kick plate.
In the case where the kick plates of the steps are depressed, a gap may occur between adjacent steps. The kick plate reinforcement has a function of making the kick plate of the step more rigid to prevent damage to the kick plate, thereby preventing occurrence of a gap between adjacent steps due to damage.
Additionally or alternatively, the thickness of the kick plate may be increased to prevent damage to the kick plate.
The solution to the problem also provides a conveyor system for an escalator, wherein the conveyor system comprises a transition area, a step chain and a plurality of steps. In particular, the steps are connected to the step chain in a fixed manner at a first support point. In particular, the steps are connected to the step chain in a loose manner at the third support point via the kick plate shaft. In particular, the kick plate shaft is connected to the step chain via a dedicated fitting as described above.
In one arrangement, the step chain includes an inner roller and an outer roller. In particular, at least at the first support point of each step, the outer rollers are adjusted to accommodate the step chain. In particular, the inner and outer rollers are guided in precision guide rails. In particular, the inner rollers are guided along the inner roller running surfaces of the precision guide rails. In particular, the outer rollers are spaced from the outer roller running surfaces of the precision guide. In particular, at least the outer roller is in contact with the outer roller running surface in the case of rotation of the steps.
In another arrangement, the pull roll, which is adjusted to accommodate the second support point of the step, is guided by a precision guide rail.
The step chain is guided by the inner and outer rollers, and the pull roller of the step is guided by the precision guide rail, so that the stability is increased.
In case a user stands above the rear edge of the step, a major part of the weight force acting on the step due to the user acts on the first support point in an upward direction and on the second support point in a downward direction, thereby generating a rotational momentum in the step. At least the outer roller is in contact with the outer roller running surface of the precision guide rail in the event of rotation of the step. Thus, the rotation is reduced by the precision guide rails, significantly increasing the stability of the steps.
The solution to this problem also provides a method of diverting a step configured as described above within a conveyor system as described above, wherein, in order to divert the step in the transition region, the kick plate is folded towards the underside of the tread plate via a hinge.
In particular, when folded, the kick plate is guided in a predetermined curve defined by curved sliding guides of the kick plate. In particular, the kick plate rotates about a kick plate axis, wherein the wheels of the kick plate axis roll within the curved sliding guides.
The steps are fixedly connected to the step chain at a first support point and the steps are loosely connected to the step chain via a kick plate shaft at a third support point. Due to the step chain path during the turn in the transition area and the sliding of the kick plate shaft in the curved slide guide, the kick plate of the step is automatically folded towards the underside of the tread plate when entering the turn.
Likewise, when leaving the transition area, the steps automatically unfold due to the trajectory of the step chain.
In a further embodiment, during deployment of the steps, the kick plate is guided in a predetermined curve defined by the curved slide guide. In particular, the kick plate shaft slides within a curved sliding guide.
In this way, collisions between adjacent steps are avoided.
The special arrangement of the steps according to the invention, wherein the kick plate of each step comprises at least a curved slide guide guiding the kick plate in a predetermined curve when folding the step, enables a turn in the transition area of the escalator with a very small turning radius, wherein the kick plate remains within a controlled distance from the adjacent step during folding and unfolding of the step. Therefore, most of the components of a typical escalator do not need to be changed when using steps according to the invention.

Detailed Description
Fig. 1 is a schematic view of a conveyor system 10 in the lower end of an escalator according to the invention.
The conveyor system 10 includes a transition region 11, a step chain 12, and a plurality of steps 20. In the transition region 11, the steps 20 of the escalator are diverted.
Each step 20 comprises a tread plate and a riser plate, wherein the tread plate and riser plate are connected to each other via a hinge, see fig. 2.
When leaving the transport area of the escalator and entering the transition area 11 at one end of the escalator, the steps 20 are guided in such a way that the treads of the steps 20 are in a plane before they turn back to the other end of the escalator.
Each step 20 is configured to fold via a hinge at least during steering in the transition region 11.
During a turn, in particular in the lower transition area 11 at the lower end of the escalator, the kick plates of the steps are folded towards the underside of the tread plates of the steps.
By folding the steps during the turn, the turn radius can be reduced. Therefore, the depth of the escalator pit can be reduced.
Fig. 2a and 2b show the steps of the conveyor system of fig. 1. Here, fig. 2a shows the steps 20 in a transport configuration, wherein the steps 20 are deployed. Figure 2b shows the steps 20 in a folded state.
The step 20 includes a tread plate 21, a kick plate 22, and a hinge 23 connecting the tread plate 21 and the kick plate 22 to each other.
Fig. 3a to 3d show detailed views of the steps 20. Of these, fig. 3a and 3b show the steps 20 from the upper side, while fig. 3c and 3d show the steps 20 from the lower side.
Each step 20 includes a first support point 24 and a second support point 25 on each side of the step. At the first support point 24, the steps 20 are connected in a fixed manner to the step chain 12. At the second support point 25, the pull roll 251 is adjusted to accommodate the step 20.
The kick plate 22 of each step 20 includes at least a curved slide guide 221. The curved slide guide 221 is configured to guide the kick plate 22 in a predetermined curve as the steps 20 are folded during a turn in the transition region.
The shape of the curved sliding guide 221 is adapted so that a controlled distance is maintained between the kick plate 22 and the adjacent step 20 during a turn. In this way, collisions between adjacent steps 20 during a turn are avoided.
Furthermore, each step 20 comprises a third support point 26, wherein at the third support point 26 the step 20 is connected to the step chain 12 in a loose manner via a kick plate shaft 261.
The kick plate shaft 261 includes a wheel 262, wherein the wheel 262 is configured to roll within the curved sliding guide 221 of the kick plate 22.
As can be seen in fig. 3a, the step chain 12 comprises an inner roller 121 and an outer roller 122. The inner rollers 121 and the outer rollers 122 are guided in precision guides (see fig. 4a and 4 b).
Fig. 4a and 4b show detailed views of the first support point 24 of the step 20. Here, fig. 4a shows a detailed view of the connection of the outer roller 122 and the inner roller 121 with the first support point 24 of the step 20. Figure 4b shows a detailed view of the guidance of the inner and outer rollers 121, 122 of the step chain 12 and the pull rollers 251 of the steps 20.
At the first support point 24 of the steps 20, the outer rollers 122 are adjusted to accommodate the step chain 12. The inner roller 121 and the outer roller 122 of the step chain 12 are guided in the precision rail 13. Here, the inner roller 121 is in contact with the inner roller running surface 131. The outer roller 122 is spaced from the outer roller running surface 132.
Furthermore, the pulling roll 251, which is adjusted to the second support point 25 of the step 25, is guided by the precision rail 13. The pull roll 251 is in contact with the inner roll running surface 131.
In case a user stands above the trailing edge of the step, a major part of the gravitational force acting on the step due to the user acts on the first support point in an upward direction and on the second support point in a downward direction, thereby generating a rotational momentum in the step.
With the steps 20 rotating, at least the outer rollers 122 contact the outer roller running surface 132 of the precision rail 13.
Therefore, the rotation of the steps 20 is reduced by the precision guide rails 13, and the stability of the steps 20 is significantly increased.
Fig. 5 shows a closer view of fig. 3 c. Here, the kick plate 22 of each step 20 includes a kick plate reinforcement 222.
The kick plate reinforcement 222 has the function of making the kick plate 22 of the step 20 more rigid to avoid damage to the kick plate 22 and thus to avoid gaps between adjacent steps 20 due to damage.
Additionally or alternatively, the thickness of the kick plate 22 may be increased to prevent damage to the kick plate 22.
Fig. 6 shows the transition region 11, in which the steps 20 turn.
During the turn, the pulling rollers of the steps are guided around a curved track of small turning radius, so that the depth of the pit can be reduced, in particular so that the depth d of the pit is reduced to d <1 m.
In order to turn the step 20 in the transition region 11, the riser 22 of the step 20 is folded via a hinge towards the underside of the tread 21. When folded, the kick plate 22 is guided in a predetermined curve defined by the curved sliding guide 221, wherein the wheels 262 of the kick plate shaft 261 roll within the curved sliding guide 221.
Since the steps 20 are connected to the step chain in a fixed manner at the first support point and are connected to the step chain 12 in a loose manner via the kick plate shaft 261 at the third support point, the steps 20 are automatically folded when guided by turning according to the trajectory of the step chain 12.
Thus, when entering the transition region 11, the kick plate 22 is folded towards the underside of the step 21. Likewise, when leaving the transition region 11, the steps 20 automatically unfold due to the trajectory of the step chain 12.
During deployment, the guided kick plate 22 is guided in a predetermined curve defined by the curved sliding guide 221 of the kick plate 22. At this time, the kick plate 22 is rotated about the kick plate shaft 261, wherein the wheels 262 of the kick plate shaft 261 roll within the curved slide guide 221.
As shown in fig. 7, the kick plate shaft 261 is connected to the step chain 12 via a dedicated fitting 263.
The fitting 263 includes an external thread 2631 fixed to the step chain 12 and a coupling nut 2632 fitted on the external thread 2631.
The fittings 263 enable the kick plate shaft to be easily connected and disconnected with the step chain, and thus the steps to be easily installed and removed from the escalator conveyor system.
