Description

The invention relates to a running shoe according to the preamble of claim 1.

Parallel slide and tilt fittings are known. They are called so-called Parallel sliding tilt doors or windows, used, for example, for living spaces the largest possible opening width for the opened door or for the opened one Window e.g. to achieve a garden, a terrace, etc., without being in the open Condition of the door or window sash disturbing into the room. Part of the Parallel sliding and tilting fittings used in this case are i.a. the so-called Running shoes, each in the lower part of the wing, i. at the local transition between the lower horizontal and horizontal spar of the sash with attached to a housing formed by a bearing element. For example when opening the window or the door the necessary Ausstellbewegung of the To allow wings, a Ausstellarm is pivotally mounted on the housing with one end attached, with its other end hinged to the housing of a trolley connected, for a parallel sliding movement of the wing in a running rail having engaging track rollers.

To compensate for tolerances, for example, in the manufacture of the door or the Window, when mounting the fittings, etc. is u.a. the possibility of a Height adjustment to the respective running shoe necessary. It is known here, the To provide height adjustment in a joint with which the extension arm hinged with the housing of the bearing element is connected (EP-A-0 119 434). The joint exists for this purpose from a hinge pin which is attached at one end to the stay and with its other end with at least one radial bearing and a thrust bearing in a bearing sleeve is mounted, which in turn for the height adjustment in the direction of Axis of the hinge pin adjustable in the housing of the bearing element of the Running shoe is provided, and in fact that the bearing sleeve with a with a Externally threaded threaded portion in a threaded bore of the housing is guided. By a clamping or locking screw, the bearing sleeve against secured unwanted twisting, i. fixed the respective height adjustment become.

Alone by the use of the bearing sleeve, but also by the use a arranged on the hinge pin Axialdrucklagers over which the Supporting bearing sleeve on the top of the extension arm, this is known construction relatively expensive and also requires a relatively large height. Furthermore, the Securing the bearing sleeve against unwanted rotation by the Inadequate locking screw, which also has a relatively high torque must be attracted.

Also known is a running shoe for a parallel sliding fitting (DE 30 40 375 A) for windows or doors made of metal. The extension arm of this Running shoe is at one end by means of a hinge on a window or Hinged door frame. The joint consists of a provided on the stay Pivot and a this pivot pin closing, with the window and Door frame to be connected bearing bush. The pivot pin forms at one end Thrust bearing, against which an adjusting screw is applied, for a Height adjustment or, axial adjustment of the joint in the bearing bush by means a thread is provided axially adjustable. Special means of locking or Fixing the adjusting screw are not provided.

The object of the invention is to show a running shoe, despite the possibility a height adjustment has a simplified construction and cheaper can be made.

To solve this problem is a running shoe according to the Claim 1 is formed.

Advantageous developments of the invention are the subject the dependent claims.

In the invention, a slider is used as a securing element, which in a Position the adjustment or adjustment for a height adjustment releases and in one second position blocks the height adjustment by the adjustment. At this Execution are in particular the disadvantages of a safety screw avoided.

The adjusting element forms, for example, one in the axial direction of the hinge pin adjustable contact surface against a supporting or counter surface on the free End of the hinge pin of the joint rests. The height adjustment is thus without an elaborate bearing sleeve possible. Overall, the training of the invention is a low-cost training of the running shoe with height adjustment, without the load capacity too weaken or the ease of use and the adjustment options limit. Expensive thrust ball bearings are in the inventive Training avoided.

The securing element is preferably a slider, which in a advanced position releases the adjustment for the height adjustment and in a retracted position blocks the adjustment. This training has Furthermore, the advantage that when placing the usually to cover the Functional elements and in particular the bearing element of the running shoe cover profiles used this slide inevitably in the height adjustment locking position must be pushed back so attaching the Cover profiles is possible.

The latter is with a so-called Parallel sliding tilt fitting around a lower horizontal, parallel to the plane of the Wing 4 lying axis tiltable and in a direction perpendicular to the plane of the Blendrahmens 2 extending axis moved out of this frame or ausstellbar and in this issued state parallel to the plane of the window frame. 2 displaceable, in such a way that the then completely open wing 4 before the Fixed field 3 is arranged.

Such Parallelschiebe- and tilt fittings are known. An essential Part of such fittings are at the lower horizontal bar 5 'of the Sash 5 in the corners and following the vertical bar 5 "of Sash frame 5 provided running shoes 6, of which a running shoe in the figures 4 and 5 is shown in detail. This running shoe consists essentially of the mounted on the casement bearing part 7 with housing 7 'and a carriage 8, the or the housing 8 'via a stay-9 with the housing 7' articulated connected is. The extension arm 9 is for this purpose at one end 9 'by means of a Articulated bolt 10, which is part of a hinge 11, pivotally mounted on the housing 7 ' and at the other end 9 "via a hinge pin not visible in the figures hingedly connected to the carriage 8. The axes of both hinge pins are parallel to the axis of the vertical spar 5 ". On the carriage 8 are two in Carriage longitudinal direction offset from each other rollers 12 freely rotatably mounted, and although each about an axis perpendicular to the plane of the movable wing. The two Rollers 12, of which only one roller 12 is visible in FIG. 4, engage in one common lower, horizontal track 13, which at the lower vertical Holm 2 'of the frame 2 is provided.

For example, to compensate for tolerances in the production of stick or Blendrahmens and / or the wing 4, to compensate for tolerances during assembly the elements of the parallel sliding and tilting fitting, in particular the Running shoes 6 it is u.a. necessary, a height adjustment, i. an adjustment in an axial direction parallel to the vertical spar 5 "for the wing 4 and thus to provide between the housing 7 'and the carriage 8. This vertical Adjustment via a height adjustment device, which in the figures generally is denoted by 14 and between the housing 7 'and the end 9' of the Ausstellarmes 9 acts, in the direction of the axis of the hinge pin 10th The latter is fixed at its lower end in FIG. 5 in the end 9 'of FIG Ausstellarmes 9 anchored. With his over the top of the stay 9 projecting end of the hinge pin 10 by means of two bearings 15 and 16, the are designed as needle bearings, in the housing 7 'rotatable about its longitudinal axis stored, in a bearing opening 17, which is the Ausstellarm the 9th facing bottom of the housing 7 'is open. The bearings 15 and 16 are Furthermore, designed so that the housing 7 'in. by a predetermined Verstellhub Direction of the axis of the hinge pin 10 relative to this for the height adjustment is mobile.

The height adjustment device 14 consists essentially of an adjusting bolt 18, which is in the region of its one end, i. in the representation of Figures 5 and 6 in Part of its lower end forms a portion 18 ', which in a ball head 19th ends. This forms a frontally spherical convex arched bearing or Support surface of the adjusting bolt 18th

The adjusting bolt 18 also has a portion 18 '' with enlarged Outer diameter, which also occupies the greater length of the adjusting bolt 18. At the Section 18 ", the adjusting bolt 18 is provided with an external thread 20, wherein the turns of this external thread 20 are shaped so that the section 18 " in addition to the external thread 20 a deviating from the circular outer contour, i.e. in the illustrated embodiment, an outer contour in the form of a hexagon having.
