Definitions

  • the invention relates to a segment of a handrail deflection band for use with a W-shaped handrail guide profile, the handrail guide profile having a first recess, an elevation and a second recess between two side walls.
  • the segment comprises a base body with a support surface for resting on the elevation of the handrail guide profile, with an axial section for receiving a rolling body extending to the side of the support surface in the transverse direction of the base body.
  • the invention further relates to a handrail deflection band formed from a plurality of segments and a handrail deflection device with a W-shaped handrail guide profile, which has a first recess, an elevation and a second recess between two side walls, and with a handrail deflection band formed from a plurality of segments.
  • Escalators and moving walks usually have a balustrade with a powered, endless handrail. It is known to guide and redirect the handrail of an escalator or a moving walk over rolling bodies, particularly in the deflection area of the handrail, i.e. at the ends of the balustrade. This ensures that the handrail is guided smoothly and evenly, which has a positive effect on the wear of the handrail and the smooth running of the handrail. Different solutions have been developed for this.
  • the DE 295 00 800 U1 a handrail deflection device with a handrail belt guided over the balustrade is known, the handrail belt having several ball bearings arranged one behind the other over which the handrail belt rolls.
  • a handrail deflection device which comprises a W-shaped handrail guide profile and a flexible element with roller bearings arranged therein.
  • a handrail deflection device with a W-shaped handrail guide profile is known.
  • a handrail chain is included in the handrail guide profile a plurality of segments designed as plain bearing supports, with rollers being arranged on the segments over which a handrail can roll.
  • the DE 20 2010 003 769 U1 discloses another handrail chain for handrail guidance in the deflections at the top and bottom of escalators and moving walks.
  • a disadvantage of the known solutions for guiding and redirecting a handrail of an escalator or a moving walk is, among other things, that a handrail band or a handrail chain formed can be set in motion, in particular in vibration, by the moving handrail. These movements not only increase wear on the handrail but also lead to noticeable noises and thus a reduction in comfort of use. If individual segments of a handrail band or a handrail chain are worn or defective, replacing the worn or defective segment is usually not possible or only possible with great effort.
  • the comfort of use should be increased.
  • simplified maintenance of a handrail deflection device should be made possible.
  • the proposed solution provides a segment of a handrail deflection band for use with a W-shaped handrail guide profile, the handrail guide profile having a first recess, an elevation and a second recess between two side walls.
  • the segment includes a base body with a support surface for resting on the elevation of the handrail guide profile.
  • an axle section extends from the base body in its transverse extension direction for receiving a rolling body, in particular a roller or a roller bearing.
  • the first engagement element and the second engagement element are designed such that the first engagement element and the second engagement element each extend towards the side walls of the handrail guide profile, in particular parallel or substantially parallel to the respective axle section.
  • Rolling bodies arranged on the axial sections of the segment are advantageously freely rotatable in the area of the respective recess, i.e. between the wall and the elevation.
  • the segment is advantageously made of a plastic.
  • the segment is formed in one piece, advantageously as an injection molded part. As a result, the manufacturing costs for such a segment are advantageously low.
  • at least the axle sections are part of an axle connected to the segment, in particular an axle guided through the segment.
  • the segment from the end of the first axis section to the end of the second axis section has a width between 25 mm (mm: millimeters) and 70 mm, preferably a width between 30 mm and 40 mm.
  • the diameter of the respective axle section is advantageously between 5 mm and 20 mm, preferably between 5 mm and 12 mm.
  • the segment has a length between 25 mm and 70 mm, preferably between 30 mm and 45 mm. The length extends in particular from a first first engagement element to an opposite second first engagement element or from a first second engagement element to an opposite second second engagement element.
  • the engagement elements of the segment advantageously give the segment stability when arranged in a handrail guide profile. Because the engagement elements extend towards the side walls of the handrail guide profile, the engagement elements in particular prevent or at least greatly restrict lateral rotation of the segment resting with the support surface on the elevation of a handrail guide element. This restriction of the movement of the segment arranged in the handrail guide profile also advantageously reduces the development of noise when these segments are used for the handrail deflection.
  • a second first engagement element and a second second engagement element are additionally arranged at the other end of the base body in relation to its longitudinal direction.
  • the segment therefore has a total of four engagement elements, namely two each at the opposite ends of the base body.
  • the four engagement elements are advantageously designed in the same way.
  • the second first engagement element and the second second engagement element are designed such that the second first engagement element and the second second engagement element each extend towards the side walls of the handrail guide profile, in particular parallel or substantially parallel to the respective axle section.
  • Two engagement elements therefore advantageously extend at a distance from one another towards one of the side walls of the handrail guide profile.
  • This advantageously further increases the resistance to rotation of the segment arranged in the handrail guide profile.
  • the segment is symmetrical, preferably mirror-symmetrical, with respect to a longitudinal axis running centrally in the longitudinal direction of the segment.
  • the segment is designed symmetrically, preferably mirror-symmetrically, with respect to a centrally extending transverse axis. If the segment is mirror-symmetrical both with respect to a centrally extending longitudinal axis and with respect to a centrally extending transverse axis, this results in the particular advantage that no errors can occur with regard to the orientation of the segment when inserted into a handrail guide profile.
  • the engagement elements extending to the side wall of the handrail guide profile touch the side wall.
  • the first engagement element and the second engagement element are designed such that the first engagement element and the second engagement element can each be supported against the side walls of the handrail guide profile. This advantageously further increases the resistance to rotation of the segment arranged in the handrail guide profile.
  • the first engagement element is arranged at the end of a first arm extending from the base body in its longitudinal direction and the second engagement element is arranged at the end of a second arm extending from the base body in its longitudinal direction.
  • the first arm and the second arm each form a pair of arms that are elastically resilient in the transverse direction of the base body.
  • the arms arranged at the end of the base body can be compressed against the force of a spring, i.e. in particular in such a way that the respective engagement element arranged at the ends of the arms faces the elevation can be moved.
  • the engagement elements advantageously have a recess towards the elevations, so that the deflecting arms do not directly collide with the engagement elements against the elevation.
  • the resilient design advantageously allows manufacturing tolerances in relation to the handrail guide profile to be evened out even better.
  • a clamping effect can advantageously be achieved for a segment inserted into a handrail guide profile by means of the engagement elements arranged on the spring arms, which are advantageously supported within the recesses of the handrail guide profile against the side walls of the handrail guide profile.
  • the end of a respective arm forms the respective engagement element.
  • the arm and engagement element are formed in one piece.
  • an outward-pointing branch of the first arm forms the first engagement element
  • an outward-pointing branch of the second arm forms the second engagement element.
  • the engagement elements are an extension of the respective arm in the transverse extension direction, which are further expanded towards the recesses compared to the respective arm.
  • the respective engagement element branches off at right angles from the respective arm.
  • the arm and engagement element or arm with engagement element each form an L-shape or T-shape. This advantageously allows the segment inserted into a handrail guide profile to be further secured against twisting.
  • a further advantageous embodiment provides that the first engagement element and the second engagement element protrude beyond the base body in the high extension direction.
  • this embodiment provides that the first engagement element and the second engagement element protrude beyond the base body in the high extension direction on the side on which the support surface is located.
  • the engagement elements of the segment arranged in a handrail guide profile do not end at the height of the elevation of the handrail guide profile, but rather protrude further into the handrail guide profile in the direction of the recesses.
  • the arrangement of the segment in the handrail guide profile is advantageously further stabilized and, in particular, further secured against twisting of the segment and against lateral tilting movements. This advantageously makes it possible to further reduce noise development when redirecting a handrail.
  • first engagement element and the second engagement element are further designed such that the first engagement element fits into the first recess of the handrail guide profile can intervene and the second engagement element can engage in the second recess of the handrail guide profile.
  • the engagement elements engage in the recesses of the handrail guide profile in such a way that the elevation of the handrail guide profile is arranged between the first engagement element and the second engagement element.
  • the base body has two first engagement elements and two second engagement elements.
  • two engagement elements advantageously engage in the first recess of the handrail guide profile at a distance from one another and two engagement elements engage at a distance from one another in the second recess of the handrail guide profile. This advantageously further increases the resistance to rotation of the segment arranged in the handrail guide profile.
  • the engagement elements advantageously slim down towards the recesses in the handrail guide profile.
  • the engagement elements advantageously have an insertion bevel, through which insertion into a handrail guide profile is advantageously made possible with little effort even if the handrail guide profile has large manufacturing tolerances, in particular with regard to the width of the recesses.

  • the truncated cone also has an undercut, wherein the connecting element with the connection point is moved completely over the truncated cone and the undercut provides a quasi-loss protection.
