Description

The invention relates to a balustrade profile with a handrail guide and with at least one arrangement means for arranging the balustrade profile on the upper end of balustrade panels.

The invention further relates to a balustrade with a plurality of first panels, a plurality of second panels and with at least one balustrade profile. The second panels protrude beyond the handrail guide and thus in particular form a fall protection that secures people against falls over the handrail guide. Furthermore, a passenger conveyor device, in particular an escalator or a moving walk, with such a balustrade is the subject of the present invention. The invention also relates to a method for modernizing a passenger conveyor device.

It is known to use balustrades with a plurality of first panels and a plurality of second panels, in which a handrail guide is arranged on the first panels and in which the second panels are laterally offset in relation to the first panels, in particular in passenger conveyor devices such as escalators or moving walks are arranged that the second panels protrude beyond the handrail guide. The second panels serve in particular as fall protection in order to prevent people who use the passenger conveyor from falling over the handrail of the passenger conveyor from the passenger conveyor. Since the handrail guide is arranged on the first panels of the balustrade, over which a driven, endless handrail is guided when a passenger conveyor is in operation, the first panels cannot have any desired height, but second panels are necessary, which are arranged laterally offset to the handrail guide are. In particular, it is known that handrail guide profiles are placed on the first panels.

From the WO 2006/042428 A2 For example, a balustrade for an escalator is known in which the first panels are arranged below the handrail and the second panels are laterally offset from the handrail, projecting above the handrail. The escalator is specially adapted to this balustrade.

Against this background, it is an object of the present invention to provide an improved possibility for erecting the above-mentioned balustrade. In particular, a visually appealing balustrade is to be created that serves as a fall protection. In particular, simple retrofitting of passenger conveying devices with such a balustrade, which serves as a fall protection, should also be made possible, preferably with minor adjustments to the passenger conveying device.

To achieve this object, a balustrade profile, a balustrade, a passenger conveyor device and a method for modernizing a passenger conveyor device according to the independent claims are proposed. Further advantageous embodiments of the invention are described in the dependent claims and the description and shown in the figures.

The proposed solution provides a balustrade profile with a handrail guide and with at least one arrangement means for arranging the balustrade profile at the upper end of the balustrade panels. In particular, it is provided that the balustrade profile is a balustrade profile of a passenger conveyor device, in particular an escalator or a moving walk, or a balustrade profile for such a passenger conveyor device. The balustrade profile according to the invention comprises at least one holding element spaced from the handrail guide. This at least one holding element is designed to hold at least one further panel at its lower end parallel to the handrail guide in such a way that the further panel projects beyond the handrail guide. The proposed balustrade profile thus advantageously combines the function of providing the handrail guide for guiding a driven endless handrail with the function of providing a holder for the other panels that serve as fall protection. Since a passenger conveyor device, such as in particular an escalator or a moving walk, usually has to be equipped with a balustrade profile which provides a handrail guide, a balustrade profile according to the invention can advantageously be used instead of a conventional balustrade profile. The complexity of arranging the balustrade profile according to the invention is advantageously not increased compared to the complexity of arranging a conventional balustrade profile.

in a simplified representation, a plan view of the detail of a further exemplary embodiment for a passenger conveyor device according to the invention.

In Fig. 1 shows the cross section of a balustrade profile 1 according to an advantageous embodiment of the invention. The balustrade profile 1 comprises a handrail guide 2, on which an endless handrail can be guided when the balustrade profile 1 is used as intended (in Fig. 1 not shown).

Furthermore, the balustrade profile 1 comprises an arrangement means 3 for arranging the balustrade profile 1 on the upper end of balustrade panels (in Fig. 1 not shown). In this exemplary embodiment, the arrangement means 3 is a receptacle 31 which is designed in the manner of a groove. With this receptacle 31, the balustrade profile 1 is placed on an upper end of a balustrade panel or several balustrade panels for intended use (in Fig. 1 not shown). The receptacle 31 is matched to the balustrade panel on which the balustrade profile 1 is to be placed, so that the balustrade profile 1 can be clamped with the receptacle 31 on the upper end of the balustrade panel. The receptacle 31 is in particular arranged opposite the handrail guide 2.

The balustrade profile 1 further comprises a holding element 4 spaced apart from the handrail guide 2. In this exemplary embodiment, this holding element 4 is designed as a holding profile 10 extending parallel to the balustrade profile 1 or parallel to the handrail guide 2 and is integrated into the balustrade profile 1. The holding element 4 is designed to hold at least one further panel at its lower end parallel to the handrail guide 2 in such a way that the further panel projects beyond the handrail guide 2. When the balustrade profile 1 is used as intended, this further panel serves as a fall protection.

As in Fig. 1 As shown, in this exemplary embodiment the holding element 4 is designed essentially as a U-shaped holding profile 10, the left inner side of the holding profile 10 being beveled, as in FIG Fig. 1 shown. The reason for this is that, for the intended use of the balustrade profile 1, it is provided that the at least one further panel is placed in the holding profile 10 and fixed by means of a clamping wedge which is introduced on the left side of the holding profile 10. The fixation by means of the clamping wedge is further improved by the inclined inner edge of the retaining profile. In particular, a glass terminal strip is provided as a holding profile 10.

The in Fig. 1 The advantageous embodiment shown, the balustrade profile 1 is formed in one piece together with the handrail guide 2 and the retaining profile 10, that is, as a single coherent part. This means that the holding element 4 is in particular not arranged on the balustrade profile 1 or the handrail guide 2 by fixing means, such as screws. In particular, it is provided that the balustrade profile 1 is made of metal. In particular, it is further provided that the balustrade profile 1 is a continuously cast profile, preferably an aluminum continuously cast profile.

This in Fig. 1 The balustrade profile 1 shown comprises between the arrangement means 3, that is the receptacle 31, and the holding element 4, that is the holding profile 10, in particular a support structure by which the holding profile 10 is spaced from the handrail guide 2. This support structure can in particular be designed like a cantilever arm which, like the holding profile 10, also extends over the entire length of the balustrade profile. In this embodiment, the balustrade profile 1 has a framework structure in its cross section. On the upper side of the balustrade profile 1, that is to say on the side that has the handrail guide 2, the balustrade profile 1 is closed in the area between the handrail guide 2 and the holding profile 10 by an upper profile surface 7. On the lower side of the balustrade profile 1, i.e. on the side on which the receptacle 31 is arranged, in the exemplary embodiment the lower area, starting from the receptacle 31 to the right outer end of the balustrade profile 1, is closed by a continuous lower profile surface 8. Between these profile surfaces 7, 8 connecting struts 6 are formed, between which cavities 5 are located. On the one hand, this increases the stability of the balustrade profile 1. On the other hand, material and weight are saved.

When the balustrade profile 1 is used as intended, the closed profile surface 7 advantageously prevents body parts of people or objects from getting into the area between the holding element 4 and the handrail guide 2.
