摘要:
The step support (17) or plate support comprises a rear crossmember (22) and a front crossmember (24) which together form a plane (E3) for receiving the tread element (9). There are two outer step cheeks (20.1, 20.2), wherein one of the step cheeks (20.1) is arranged on the right and one of the step cheeks (20.2) is arranged on the left, substantially perpendicular with respect to the crossmembers (22, 24). The two crossmembers (22, 24) are manufactured from deep-drawing sheet metal and are welded or joined or riveted or screwed or adhesively bonded or clinched to the step cheeks (20.1, 20.2) or plate cheeks to form a load-hearing frame. The height (H2) of the crossmembers (22, 24) at its ends is smaller than the height (H3) of the crossmembers (22, 24) in the center, with the result that the crossmembers (22, 24) have a curved shape.

A wheel for driving a flexible handrail of an escalator or moving walk turns about an axis of rotation, and has a tire with a tire cover that may be filled with pressurized gas and a contact surface that is intended to rest against the handrail. The contact surface is formed on a power transmission element that has a reinforcing insert and is accommodated in a peripheral recess of the tire cover.

A handrail for an escalator or moving walk that has a fixed guide device and a handrail body that moves along the guide device when in operation is disclosed. The guide device has a form-giving guide section that contains a lip-guide that extends along a longitudinal direction of the guide section. The handrail body is strip-shaped and has two edge-lips that extend along two longitudinal edges of the strip-shaped handrail body. The edge-lips are formed in such manner that they run parallel to the longitudinal direction when the handrail body moves in the lip guide. The guide section essentially defines the form of the handrail in both the direction parallel to the longitudinal direction and in a cross-sectional plane perpendicular to the longitudinal direction.

The invention relates to a handrail (1), used in particular for escalators or moving walkways, comprising a plurality of grip elements (10) or grip segments (10) arranged next to one another. The grip elements or grip segments (10) consist of a base body (11) that has an outer shell (12) or cover layer (12) and several inner chambers (15) delimited by the outer shell (12) or cover layer (12). The base body (11) has many or several reinforcing ribs (16 to 20 and 16′ to 20′, 35 and 35′ and 36 and 54). The outer shell or cover layer (12) is continuous in a grip region (13). The reinforcing ribs (16 to 20 and 16′ to 20′, 35 and 35′ and 36 and 54) divide the interior (15) into separate, independent chambers (21-24, 37-38, 55). This provides excellent thermal insulation and excellent soundproofing or noise insulation.
摘要:
An escalator with an endless formation of successive steps, each having a step surface, a front surface or step-riser and each side, a sideways directed cheek. Provided in the area of each cheek is at least one roller that projects transversely sideways, and is guided along laterally mounted, diagonally running roller-rails of the escalator. On each step in the area of the front surface or step-riser at least one emergency guide hook is fastened in such manner that the emergency guide hook of a higher lying upper first step supports itself against an area of the cheek of the next lower lying second step, should the step be eccentrically loaded in the area of the step-tread.

A compactly constructed guide system has a run surface for guiding the run of the chain rollers. To guide the sides of the steps, a sliding pin arranged on a step rests on a side surface. A counter-surface serves as a counter-guide for the chain rollers and prevents the chain links from being pushed together. By means of an encapsulation, the step rollers, the chain links, and the running surface can be protected from dirt, dust, water, objects, etc. For run guidance of the step roller, a running surface is provided. An oil collecting channel prevents dripping of lubricating oil. The guide system rests on a bracket plate projection and is releasably connected to the bracket plate. The single-piece guide system is simple and efficient to install and can be accurately positioned at the sides against stops.

A wheel for driving a flexible handrail of an escalator or moving walk. The wheel has a power transmission element that can be turned about an axis of rotation and that has, on its circumference a contact surface through which an outwardly acting radial force can be exerted. The wheel also has two base sheaves that are arranged coaxially to the power transmission element. Each base sheave has a plurality of slits that are arranged in the outer edge area of the base sheave and extend toward the axis of rotation. The slits of one base sheave form, with the slits of the other base sheave, slit pairs. The wheel has a circumferential cover with an inside surface against which the contact surface of the power transmission element rests. A plurality of pins is arranged in the circumferential cover, each pin engaging a separate respective slit pair.
摘要:
A clinching tool (20) for producing a load-bearing, supporting or stable connection of a first metal workpiece (11) with a second metal workpiece (12). The clinching tool (20) comprises a die tool (20) and a counter-tool (30) which together form and join, by local plastic reshaping or deformation of the metal workpieces (11, 12), a clinch connection (13) which connects or permanently joins the first metal workpiece (11) and the second metal workpiece (12). The die tool (20) comprises a die having a flank (25) arranged concentrically with respect to the rotational axis (24). The flank (25) has a front end surface (23) perpendicular to the rotational axis (24). The flank (25) is conically shaped at least in the lower transition region (21) to the front end surface (23) and has a flank angle (W, W1, W2) smaller than or equal to 10 degrees, preferably smaller than or equal to 5 degrees.
