Definitions
- the invention relates to a device for guiding a handrail, in particular in the return run, an escalator or an escalator with a plurality of spaced-apart guide elements which can be inserted into the open area of the handrail and brought into active connection with corresponding inner surface areas of the handrail.
- Both immovable and movable guide elements which are particularly known in the return run of the handrail, i.e. on the base side, are provided, which engage in the free space of the handrail and can be brought into operative connection with a wide variety of inner surface areas of the handrail in order to ensure the guidance (straight running) of the handrail in this way.
- the guide elements can be designed, for example, in the form of rotatable rollers, rollers or the like, which can be moved about a horizontal or vertical axis.
- T-shaped stationary, i.e. H. immovable guide elements to which the handrail can be attached are also known in cross section.
- the lip areas are protected because the T-profile is provided below it.
- the corresponding inner surface areas are weakened by increased friction, so that here too there is only a short service life.
- the aim of the object of the invention is to design a device by means of which the inner surface areas of the handrail are not affected while at the same time being optimally guided (straight running), so that a longer service life is possible.
- the respective guide element comprises at least one carrier body which is connected directly or indirectly to components of the escalator or the moving walk and which is provided in the region of its ends with at least one rotating body which is relatively movable relative to the carrier body.
- the support body described in the object which is initially aligned parallel to the open area of the handrail, is introduced together with the rollers into the open area of the handrail.
- the carrier body together with the rollers is pivoted about its vertical axis until the rollers come into contact with the corresponding inner surface or are at least arranged in their immediate vicinity. The carrier body is then fixed and locked in this position.
- the carrier body can be directly or indirectly connected to components of the escalator. According to an idea of the invention, the carrier body interacts with a holder which is fixed on the base side.
- the subject matter of the invention is preferably applicable for the return area of the handrail, the subject matter of the invention can also be used for guiding the handrail on the side of the balustrade, provided the balustrade is designed appropriately.
- the carrier body is preferably mounted so as to be pivotable relative to the holder about a vertical axis, the pivot connection being provided approximately in the center of the carrier body and including a bolt which is adjustable in its longitudinal direction and which can be fixed and locked in various positions.
- the rotating bodies are preferably formed by rollers which can be rotated about a vertical axis and which are connected to the carrier body in its end regions. The diameter of the respective roller is selected so that it can be easily passed through the open area of the handrail without coming into contact with the spaced lips of the handrail.
- the handrail is guided in particular in its return run in such a way that it continuously comes into contact with one or the other roller of the respective guide element in the area of the spaced-apart guide elements, with damage occurring as a result of the rolling movement taking place between the inner area of the handrail and the outer peripheral surface of the roller the handrail is safely avoided.
- Fig. 1 to 3 different assembly situations of the guide device according to the invention for the handrail of an escalator or an escalator.
- Fig. 4a - c representation of a locking device in different positions. 1 to 3 show different positions of the guide device 1 according to the invention for the handrail 2 of an escalator or a moving walk, not shown.
- the handrail 2 is provided in the return run, wherein it is placed on spaced support rollers 3.
- the handrail 2 has an upwardly open area 4 (free space) which is delimited in its upper area by spaced lip areas 5, 6.
- the free space 4 has a T-shaped profile in cross section, the mutually opposite inner surface end regions 7, 8 being rounded.
- the guide element 1 consists of a holder 9, which is connected to a carrier body 11 via a pin 10 that can be raised and lowered.
- the adjustment mechanism of the bolt 10 is not shown in this example.
- the carrier body 11 in turn interacts with rollers 12, 13 arranged underneath, which are each rotatable about a vertical axis 14, 15.
- FIG. 2 illustrates that the guide element 1 is introduced into the free space 4 by lowering the bolt 10 along its vertical axis 16 until the rollers 12, 13 are provided below the lip edges 17, 18, the support body 11 being outside the handrail 2 remains.
- the orientation of the carrier body 11 can be seen here analogously to FIG. 1.
- FIG. 3 now shows the installed state of the guide element 1.
- the carrier body 11 together with rollers 12, 13 is pivoted about the vertical axis 16, so that it assumes a predeterminable position in which the rollers 12, 13 are brought at least up to the vicinity of the inner surface regions 7, 8.
- the guide element 1 is fixed and not actuating elements shown further (eg a bayonet catch or the like) locked.
- the direction of movement of the handrail 2 is indicated in FIG. 3, the roller movement about its vertical axes 14, 15 also being indicated by arrows.
- a slight distance is provided between the rollers 12, 13 and the inner surface areas 7, 8 in the installed state, so that the handrail 2 can come into contact with the respective rollers 12, 13 in the course of its extension in the range of these tolerances without damaging the inner surface areas 7, 8.
- FIGS. 4a-c show representations of a locking device 19 for the guide element 1 described in FIGS. 1 to 3 in different positions.
- the locking device 19 is formed by a spring 20 which surrounds the bolt 10 and extends between counter surfaces 21, 22.
- the counter surface 21 is provided in the region of a knob 23, while the counter surface 22 is formed by a component 24 with a U-shaped cross section.
- the component 24 corresponds to the holder 9 shown in FIGS. 1 to 3.
- the carrier body 11 is equipped with lugs 25, 26. Following the positioning of the guide element 1, the free legs of the component 24 interact with the shoulders 25, 26 of the carrier body 11 in a bayonet-like manner, so that the guide element 1 is fixed and locked in the desired position.
