Description

Ground cover of a passenger conveyor

description

The present invention relates to a flat bottom cover for covering an access area of a passenger conveyor and a so equipped

Person conveyor and a method for retrofitting a

People conveyor.

Passenger conveyors such as escalators or moving walkways generally serve to carry people or objects standing on a stepped step strip or a palletized pallet strip standing along an inclined or horizontal path. The steps or pallets are thereby displaced by means of a conveyor along the oblique or horizontal path, so that, for example, a person can enter the person conveyor in a first access area and climb onto one of the steps or one of the pallets, then together with the latter to an on opposite end of the person conveyor located second access area to be transported, where the person the

Leave person conveyor again.

In the access areas at opposite ends of the step belt or pallet band, a flat floor covering generally serves as a walkable floor to cover an opening of an underfloor existing space or area with, for example, technical facilities of the person conveyor upwards, so that people on the access area towards the moving Steps or pallets can get. In the underfloor existing spaces can at one end of the passenger conveyor

For example, be arranged with deflecting sprockets a deflection axis and at the other end of the passenger conveyor a drive whose control and a drive train with drive shaft and drive sprockets be housed.

The bottom cover can be in one of the access areas of Passenger conveyor on the one hand provide a walk-in and flush as possible transition between, for example, a floor of the surrounding structure and moving in the person conveyor stage or pallet band. On the other hand, the bottom cover can often be made removable or unfolded, in order then to the space underneath with the therein

recorded components of the passenger conveyor to be able to repair them or wait for example.

EP 0 661 229 B1 discloses one with the structural parts of a

Person conveyor connected angle frame, which as

Floor cover overlay for a cover serves. For a flush and jointless transition to the surrounding floor the corner frame is

Screws and nuts adjustable in vertical and horizontal position. To dampen the footstep noise when walking the bottom cover, the support surface of the angle frame is covered with an elastic profile, said elastic profile on the underside form-fitting manner with the horizontal leg of the angle profile of the

Angle frame is connected.

As mentioned above, in the underfloor space below the bottom cover usually the deflection of the step band of the escalator or the pallet band of the moving walkway, the cover must be securely arranged on the bottom cover pad so that regardless of the force action direction and the force application point acting on the cover , External force, which under no circumstances slips on the floor cover pad, lifts or tilts and unintentionally releases an opening to the room with the technical facilities.

The invention has for its object to provide a ground cover, which takes into account the above requirements and largely precludes faulty mounting.

This object is achieved by a bottom cover of an access area of a passenger conveyor, which is designed as an escalator or moving walk. The bottom cover has a bottom cover overlay, a first cover element and at least one subsequent cover element. Through the bottom cover, the opening of an underfloor existing space of the passenger conveyor to the surrounding, walk-in floor is at least by means of the first and subsequent to this, placed on the bottom cover pad cover flush closed. At least in the area of the first cover element and the adjoining cover element at least one device is arranged, by means of which a single possible, correct installation position of the cover on the

Floor cover overlay is specified. In the correct installation position, the first cover and the subsequent cover are flush on the

Floor cover overlay arranged resting. In the case of incorrect installation position, at least part of the adjoining cover element on the bottom cover overlay is visibly protruding and therefore not flush due to the device. Flushing thus means that, when correctly mounted, the cover elements with the bottom cover support and its surrounding bottom form a flat, accessible surface.

We do this by the fact that the device has a positioning element, through which a correct position of the first cover on the

Floor cover overlay and thus the correct installation position of the first cover is predetermined, which can be brought by a displacement of the first cover on the bottom cover pad, the positioning element in positive operative connection with the bottom cover pad and / or with the first cover.

By visibly surviving at least a portion of the subsequent

Cover element is immediately recognizable that the first cover was not mounted correctly. Thus, the device indicates a dangerous state for laymen and enforces a review and remedy the shortage. The device may be configured differently in order to obtain a visible protrusion of the subsequent cover element in case of incorrect installation. Depending on the design of the device, these or parts thereof, for example, on the bottom cover pad of

Floor cover or be arranged on one of the cover. In one embodiment of the invention, the device is positioned in a region between the first cover member and the adjoining cover member, arranged with a fastener on the bottom cover pad. In order to obtain a partial overhang of the subsequent cover member in case of incorrect mounting, the device includes a lever pawl having a first lever arm, a bearing point and a second lever arm. The bearing point is arranged between the two lever arms and the positioning element on the first lever arm. The second lever arm extends into the region of the subsequent cover element. In the correct installation position, the positioning element protrudes into a recess of the first cover, wherein the second lever arm is matched to the Bodenabdeckungsauflage and on the subsequent cover that the subsequent cover flush and therefore just then and without visible protrusion, can be placed on the bottom cover pad ,

In case of incorrect installation position, the positioning element is on the

Bottom cover overlay launched first cover and holds the lever pawl in a pivoted about the bearing position. In this position, the second lever arm protrudes beyond the support plane of the bottom cover pad, so that the subsequent cover, which is placed on the bottom cover pad, abuts the second lever arm and thereby at least partially from the

Floor cover pad is raised. This surviving now clearly indicates that the first cover is not yet in the correct position on the

Floor cover overlay is arranged and rests for example with its leading edge too far forward on the Kamplatte or particularly bad, not supported with its leading edge on the comb plate.

As soon as by a linear displacement of the first cover on the

Floor cover pad the positioning member finds the recess of the first cover, the lever pawl pivots back, the positioning member projects into the recess and the second lever arm lowers, so that it no longer protrudes from the support plane of the bottom cover pad. The pivoting back of the lever pawl is preferably carried out by gravity, which is why the second lever arm should have a greater mass moment of inertia than the first lever arm.

Of course, the pivoting back, for example, with a torsion spring be obtained. The subsequent cover element can now be placed flush on the bottom cover overlay.

Similarly, a further embodiment of the invention acts. In this embodiment, the device with a fastener on the first

Cover arranged. As in the previously described embodiment, the device is also positioned in a region between the first cover element and the adjoining cover element. The second embodiment of the device also has a lever pawl with a lever arm, a bearing point and the positioning element arranged on the lever arm. However, the bearing is arranged at a first end of the lever arm. In the correct installation position that stands out

Positioning element in a recess of the bottom cover pad and the second lever arm end is arranged in the region of the subsequent cover element.

In the correct installation position, the positioning member projects into a recess of the bottom cover pad, wherein the lever arm is adapted to the bottom cover pad and the subsequent cover that the subsequent cover flush and therefore just then and without visible protruding or protruding on the bottom cover pad can be arranged. In case of incorrect installation position, the positioning element is on the

Floor cover pad and holds the lever pawl in a pivoted about the bearing position. In this position, a second Hebelarmende protrudes beyond the support plane of the bottom cover pad, so that the subsequent

Covering element, which is placed on the bottom cover pad, is present at the second Hebelarmende and thereby at least partially from the

Floor cover pad is arranged and, for example, with its leading edge too far rests on the front of the Kamplatte or not supported with its front edge on the comb plate.

As soon as by a linear displacement of the first cover on the

Bodenabdeckungsauflage the positioning element, the recess of the

Ground cover pad returns, the lever paw returns, the Positioning member projects into the recess and the second Hebelarmende lowers so that it no longer protrudes from the support plane of the bottom cover pad. The subsequent cover element can now be flush with the

Floor cover pad to be hung up.

Preferably, the position of the device is to the bottom cover pad

or to the first cover by the at least one

Adjustable fastener. As a result, manufacturing tolerances between the recess and the comb plate can be compensated. If the fastening element has, for example, a screw connection and further components, a

Slot, a slot or the like, be provided in one of the components to be connected.

For example, as such a component, the fastener includes a bearing angle at which the bearing point of the lever pawl is pivotally mounted or rotatable. In this bearing angle and the above-mentioned slot can be formed.

To a possible backlash-free positioning of the first cover for

To achieve bottom cover overlay, a breakthrough in the first cover and a recess may be formed in the bottom cover pad, wherein in the correct installation position, the positioning element extends into the recess and into the opening.

To further increase the safety may further between the bottom cover pad and the first cover a fuse element, preferably one

Screw connection may be provided with a wing nut. Of course, the fuse element and a locking device with a variety of

Be formations. It may, for example, be a rotary bolt or a sliding bolt. The locking device can also be combined with a lock, for example with a cylinder lock. For example, a so-called

Spring snap (Spring-Bolt) are used with latching nose, wherein the bolt is held up by an elastic element. Preferably, the device also has at least one sensor or switch, by means of which the correct or incorrect installation position of the cover element can be monitored. The easiest way this can be realized with a simple push button or switch, for example, directly the power to a drive motor or drive units of the

Person conveyor device interrupts as soon as the cover is in an incorrect installation position or missing. Of course, the cover can also be monitored by means of a sensor, the corresponding signals to a control of

Person conveying device transmitted. This can then trigger appropriate measures such as an immediate braking (emergency stop) of the step band or

Pallet band.

Since the bottom cover of a moving walkway or an escalator usually extends over a fairly large area, the at least two cover elements can have a very high weight. In order to facilitate the handling for the assembly and maintenance personnel, the bottom cover may have further covering elements, which are resting on the bottom cover pad and arranged one after the other. Associated with at least the first cover, a device is provided which enforces the only possible, correct installation position thereof.

At least the first cover because the risk of a missing or improperly mounted cover depending on its position in the order applied cover elements may be different. For example, an incorrectly mounted first cover element, which is then arranged on the comb cover plate on the bottom cover support, poses very high risks for a user, as below this first cover element moving parts of the step band or

Pallet tape are present, which could immediately detect a person falling into it and could seriously injure. Also, the cover immediately adjacent to the first cover member may still be located in this dangerous area, which is why a corresponding device provided for this

or can be assigned.

Cover elements located farther from the comb plate on the

Floor cover pad are arranged, however, cover a less critical or dangerous area of the underfloor existing space in which, for example, the control cabinet and other electrical installations,

Lubricating installations, hydraulic installations and the like are arranged more. Of course, at least one device can be provided for each cover element. The individual cover elements may have connecting elements on the end faces, which in the assembled state face other cover elements. These can be configured, for example, as a tongue and groove.

A bottom cover with a plurality of cover elements also has the advantage that only as many cover elements as necessary must be removed if, by removing the at least one cover element access to the room with the technical

Facilities should be exposed.

To make the at least partially survive an incorrectly mounted cover even better perceptible, at least one side surface of the

Cover be provided with a signal color. Instead of or in combination with the signal color, the side surface may also have at least one reflective element. Of course, for the same purpose, at least one lamp can be provided on the side surface, alone or in combination with a

Signal color and / or a reflective element. The light bulb can

be continuously lit or flashing used. Preferably, the lighting means is connected so that its power supply is interrupted immediately when the cover is in its correct mounting position. Alternatively, the light source may be connected to the power source such that it does not light up or blink when the cover member is in improper mounting position and continuously lit when the cover member in the correct mounting position on the

Floor cover overlay is arranged. In this case, it is advantageous if the light of the light source can enter the access area in order to illuminate it for the user and / or to indicate in which direction the step belt or pallet belt runs.

When assembling the inventive floor cover in an access area of a passenger equipment which is designed as an escalator or moving walk, a device is first on the first cover or on the bottom cover pad attached. Then, the first cover member is placed on the bottom cover pad. Subsequently, the first cover is brought at least by pushing in an intended, correct installation position, so that the positioning element of the device, the first cover to the bottom cover pad positioned positively. In a further step, the at least one, subsequent

Covering the first cover then fed on the

Floor cover pad arranged. Subsequently, at least a visual check is made as to whether at least a part of the subsequent cover element of the

Floor cover overlay visible.

Of course, the invention can not only be used in new escalators or moving walks. For example, an existing floor covering can be replaced by a floor covering according to the invention, thereby modernizing an existing moving walkway. Of course it is also possible to have an existing one

To complement the bottom cover with at least one device, so that even for the existing cover a single possible, correct mounting position on the

Floor cover overlay is given, wherein the correct cover assembly flush or with the bottom cover pad and the surrounding soil forming a flat walk-surface on the

Floor cover overlay is arranged resting and in case of incorrect assembly due to the device at least a portion of the first cover subsequent cover member on the bottom cover overlay is visible protruding.

The bottom cover with a device which specifies a single possible, correct installation position of the first cover on the bottom cover pad will be explained in more detail by way of examples and with reference to the drawings, wherein in all figures for the same components throughout the same

Reference numerals are used. Show:

FIG. 7 shows another side view of a bottom cover with a first cover element and at least one adjoining cover element, wherein the bottom cover has a device with a one-armed lever latch and the first cover element is shown in an incorrect installation position.

Figure 1 shows schematically in side view a passenger conveyor 100, which is designed as an escalator and a first floor El connects to a second floor E2. The person conveyor device 100 has a supporting structure 106 or truss 106 with two deflection regions 107, 108, between which an only partially shown stepped belt 105 is guided circumferentially. The step band has traction means 109 on which steps 104 are arranged. A handrail 103 is disposed on a balustrade 102. The balustrade 102 is connected to the supporting structure 106 at the lower end by means of a balustrade base 110. The person conveyor device 100 or its step band 105 can be entered via access areas 111, 112 that are present at both ends of the person conveyor device 100. The accessible surfaces of the access areas 111, 112 are bottom covers 10, which each flush the opening of an underfloor existing space 113, 114 of the passenger conveyor 100 toward the surrounding, walkable floor 115 of the floors El, E2 flush or just.

Of course, the person conveyor device 100 could also be designed as a moving walkway, wherein instead of a step band, a pallet band is arranged circumferentially and the middle part has no slope or a smaller slope than an escalator.

FIG. 2 shows the section of the access area 111 arranged in the floor El in FIG. 1 with "A" in a larger representation, so that details of FIG

Bottom cover 10 are better visible. The one shown in cross section

Floor cover 10 has a plurality of cover elements 1, 2, 3, 4, 5. The first

Covering element 1, which is arranged on the right in FIG. 2 in the area of the balustrade base 110, is formed as a hollow profile with transverse webs 9 and lies with its tapering right side 8 on a comb plate 18 belonging to a safety device. His left side ends in a separation point 7. The left

subsequent cover 2 is configured in cross-section as a rectangular Holprofil with transverse webs 9 and the other subsequent cover elements 3 to 5 are also identical in construction as hollow sections with rectangular cross-section and transverse webs 9. The cover elements 1 to 5 may be frontally connected to the separation points 7 with suitable connecting elements 14 such as spring and groove with each other. The left end face of the cover elements 1 to 5 have, for example, a groove and the right end face of the cover elements 2 to 5 a spring. Designed as an angle frame bottom cover pad 12 is attached by means of adjusting screws 21, 22 on the structure 106, so that the bottom cover pad 12 can be leveled to the level of the surrounding walkable floor 115 of the floor El. The bottom cover pad 12 may be a frame made of angle profiles. These Angle profiles can be made of sheet steel, which are cut by means of a punching process from a sheet metal plate and bent to angle profiles. The

Bottom cover overlay 12 closes the bottom cover 10 at two longitudinal sides (hidden by the bottom cover) extending in the access direction Z and a lateral side 13. All cover elements 1 to 5 are shown in their correct mounting position.

When mounting the bottom cover 10, the assembly or maintenance staff must pay particular attention that the first cover 1 rests with its tapered side 8 securely on the comb plate 18. In order to prevent slipping and tilting, the first cover 1 is firmly connected in the region of the left end face 15 by means of a securing element 16 with the bottom cover pad 12. The fuse element 10 can be a screw connection 16, for example. Since this fuse element 16 is not visible when fully assembled bottom cover 10, can not be detected if due to an assembly error, for example, the mother of the screw 16 is missing.

To exclude this situation, the present invention provides that the bottom cover 10 includes at least one device 20, by means of which a single possible, correct installation position of the at least one cover element 1 to 5 is predetermined on the bottom cover pad 12. A correct assembly is signaled that the cover 1 to 5 is arranged flush on the bottom cover pad 12. In the case of incorrect mounting, at least part of the cover element 2 adjoining the first cover element 1 is arranged so as to be visible on the floor cover overlay 12 due to the device 20.

The device 20 and its arrangement in the bottom cover 10 may be implemented in various ways. The following are possible

Embodiments described.

FIGS. 3 to 5 show a sectional side view and FIG. 6 in FIG

Three-dimensional representation of a section of an embodiment of a

Bottom cover 10 with a device 20, as mentioned in connection with Figure 2. In FIG. 3, this is designated in FIG. 2 as the first cover element 1 Part of the bottom cover 10 shown in the incorrect installation position Xi. As already described above, an insufficient or missing support of the first cover element 1 on the comb plate 18 represents a serious danger.

In order to indicate the incorrect installation position Xi and thus the potential danger, the bottom cover 10 has the device 20, which comprises a two-armed lever pawl 23, a bearing bracket 24 and a fastening element 25. At the bearing angle 24, the two-armed lever pawl 23 is pivotally mounted on a bearing 39. At the first lever arm 26 a molded as a projection positioning element 28 is arranged. The bearing bracket 24 is fastened by means of the fastening element 25 on the bottom cover pad 12. In the present embodiment, the fastening element 25 is a screw connection. Thus, the position of the device 20 is adjustable relative to the bottom cover pad 12, the bearing bracket 24 has a slot 29. The distance between the positioning element 28 and the comb plate 18 is set so that, when the installation position Xo is correct, the first cover element 1 rests securely on the comb plate 18, as shown in FIGS. 4 and 5.

The first cover element 1 has a recess 30. If the first

Cover 1 is placed on the bottom cover pad 12, the bottom 31 is shown as in the figure 3, on the positioning member 28 and pivots the lever pawl 23 in the position shown. The second lever arm 27 protrudes with a height X2 on the support plane 32 of the bottom cover pad 12 addition. If now without correcting the position of the first cover 1, a subsequent to this cover member 2 is placed on the Bodenabdeckungsauflage 12, this subsequent cover 2 will rest on the second lever arm 27 and in a visibly protruding position or the incorrect installation position Xi indicating held. As a result, it is immediately obvious to anyone that the first cover element 1 is in an incorrect installation position Xi.

In the illustrated embodiment of Figure 3 can now be moved by moving the first cover 1 on the bottom cover pad 12 in the direction of the comb plate 18, the first cover in the correct installation position Xo. This is achieved when the projection 28 can engage positively in the recess 30. Since the projection 28 can protrude into the recess 30, the Swivel lever latch 23 back, as shown in Figure 4. In this position, the second lever arm 27 no longer protrudes beyond the support plane 32, so that the subsequent cover element 2 can be arranged flush on the bottom cover support 12.

It is particularly advantageous if an incorrectly mounted cover element 1 to 5 of the bottom cover 10 directly influences the operating state of the passenger conveyor 100. In order to achieve this, as shown in FIG. 4, the correct installation position Xo of the cover element 1 to 5 can be monitored by a sensor 33 or switch 33. By the sensor 33, for example, the position of the lever pawl 23 can be tapped mechanically or optically. For this purpose, a simple switch 33 may be used, which, for example, directly interrupts the power supply to a drive motor of the step belt 105 or pallet band, not shown, as soon as the lever pawl 23 is pivoted due to an incorrect installation position Xi.

Alternatively, the switch 33 or sensor 33 can transmit a signal corresponding to the installation position of the cover element 1 to 5, for example via a signal line 34 to a control of the personal conveyor 100, not shown, so that in case of incorrect installation position Xi the control immediately initiates the standstill of the step belt 105 or pallet belt or maintains this and in the correct installation position Xo the operation with respect to the bottom cover 10 releases.

The cover element 2 can be secured in the correct installation position Xo, additionally with a securing means 16, as shown in FIG. The securing means 16 of the illustrated embodiment has a screw 35 and a wing nut 17. The screw 35 is in the recess 30 of the first

Cover element 1 is inserted and protrudes in the correct installation position Xo through an opening 36 of the bearing bracket 24. The wing nut 17 of the securing means 16 is mounted and tightened, as shown in Figure 4. The upper, provided with a rib profile 37, walk-surface of the first cover 1 includes flush (Xo = 0) of the accessible area of the subsequent cover 2, which the correctly mounted, first cover 1 adjacent to the

Floor cover pad 12 is arranged. Of course, as a securing means 16 also serve a locking device such as a spring catch or bolt on the

Bottom cover overlay 12 is fixed and in a recess of the first

Cover element 1 engages.

FIG. 6 shows a detail of the three-dimensional representation

Embodiment of Figure 3, wherein in Figure 6, only the subsequent cover 2 is shown to show its signaling elements 40. Thus, the at least partially survive an incorrectly mounted cover 1 to 5 is even better perceived, as shown by the subsequent cover 2, at least one side surface 44 of the subsequent cover 2 with a signal color 45 such as neon yellow, neon orange and the like more.

Instead of or in combination with the signal color 45, the side surface 44 may also have at least one reflective element 46. Of course, at least one light source 47 may be provided on the side surface 44 for the same purpose, as shown schematically by the arranged in a glazed groove 48 luminous body 47. The illuminant 47 may be used alone or in combination with a signal color 45 and / or a reflective element 46.

FIG. 6 also clearly shows how the positioning element 28 protrudes beyond the support plane 32 of the bottom cover support 12 so that the lever pawl 23 is actuated and raises the adjoining cover element 2 when, as shown in FIG. 3, the recess 30 of the first Cover element 1 is not arranged at this point.

FIG. 7 shows, in a sectional side view, a bottom cover 10 in a further embodiment of the invention, wherein the first cover element 2 is shown in the incorrect installation position Xi. In this embodiment, a device 50 with a fastening element 51 on the first cover 1 is arranged. As in the previously described embodiment, the device 50 is also in a region between the first cover element 1 and the adjoining one

Cover element 2 positioned. This embodiment of the device 50 has a Lever pawl 53 with a lever arm 54, a bearing 55 and arranged on the lever arm 54 positioning member 58 on. The bearing 55 is disposed at a first Hebelarmende 56. The second lever arm end 57 is arranged in the region of the adjoining cover element 2. Furthermore, the

Floor cover pad on a recess 52.

If incorrect installation position Xi, the positioning element 58 is at the

Bottom cover pad 12 and holds the lever pawl 53 in a pivoted about the bearing 55 position. In this position, the second Hebelarmende 57 protrudes far beyond the support plane 32 of the bottom cover pad 12, so that the subsequent cover 2, which is placed on the bottom cover pad 12, at the second Hebelarmende 57 is present and thereby at least partially from the

Floor cover overlay 12 is raised. This surviving now clearly indicates that the first cover 1 is not yet in the correct position on the

Bottom cover overlay 12 is arranged and, for example, with its front edge 1 1 too far on the front of the Kamplatte 18 rests or as shown in Figure 7, with its front edge 1 1 is not supported on the comb plate 18.

As soon as by a linear displacement of the first cover 1 on the

Bottom cover pad 12, the positioning member 58 finds the recess 52 of the bottom cover pad 12, pivots the lever pawl 53 back, the

Positioning element 58 projects into the recess 52 and the second Hebelarmende 57 lowers, so that he no longer far above the support plane 32 of the

Floor cover overlay 12 protrudes. The subsequent cover element 2 has an exemption 59, so that the swung-back lever pawl 53 has sufficient space and the subsequent cover 2 can be placed flush on the bottom cover pad 12.

Since the bearing 55, a part of the lever pawl 53 and in particular the

Positioning element 58 is disposed within the first cover 1, an opening 60 in the bottom 31 of the first cover 1 is formed in the region of the positioning element 58. If the first cover element 1 is in the correct installation position Xo, the positioning element 58 penetrates through both the opening 60 and the recess 52. As a result, a very low-backlash positioning can be realized be, because the positive connection via the positioning element 58, the

Breakthrough 60 and the recess 52 and not on the bearing 51st

Although the invention has been described by way of illustrating specific embodiments, it will be apparent that many more

Embodiment variants can be created with knowledge of the present invention, for example by a sensor 25 or switch 25 is used to monitor the correct assembly of the first cover 1 in each of the embodiments. Furthermore, the bottom cover 10 may also include a plurality of devices 20, 50. All embodiments can also be used with bottom covers 10, which have more than two cover elements 1 to 5. In such

Bottom covers 10 may be present for each of the cover elements 1 to 5 at least one device 20, 50. Of course, it is also possible for the second lever 27 of the lever pawl 23 to extend beyond the cover element 2 immediately following the first cover element 1, so that if the installation position Xi is incorrect, another subsequent cover element 3, 4, 5 will be raised than the first directly Cover element 1 subsequent cover 2.

Of course, existing passenger transport facilities 100 can be modernized by their existing floor coverings 10 are replaced by floor coverings 10 according to the invention or the existing floor coverings 10 are supplemented with corresponding devices 20, 50.
