The invention relates to a support arrangement for a balcony glazing or the like movable element, comprising: a first guide rail 5 for two longitudinally displaceable, weight bearing element / carrier wheel unit and a second guide rail having an element carrier / carrier wheel to be supported, in particular a support arrangement in which the element is arranged on a path of travel comprising at least two guide rails arranged at an angle to each other

A solution according to the prior art, WO 99/32752, discloses one solution in which the angular rotation of the element bearing wheel structure is achieved by means of additional pieces placed at the corner of the guide rails.

15 This solution has the following disadvantages: - Since the angle between the element groups and thus the guide rails can be any, usually between 180 and 90 degrees, the additional pieces must always be made separately for the angle in question.

- Attaching small attachments to the guide rail must be done during the installation phase at site conditions and can therefore be expensive and unreliable.

•:: - The friction between the attachment and the wheel may hinder the turning process' unless these parts are lubricated.

'·' J - When turning, the wheel will have to 'straighten' with the wheel bearing part of the wheel and * t · * · I .. 'may, at least in part, be' over empty '.

The object of the invention is to eliminate the drawbacks of the known solution and to provide a simple, easy-to-manufacture and installable, reliable support arrangement.

| ·:: 30 This task is solved by a support arrangement characterized by i »* * *.

i: · 'adjacent guide rails form a miter joint with each other so that the support:': / transmission wheel unit includes a vertical support axis and connected to the element. '·: A frame part which is pivotally supported by the support shaft and to which 2 109226 frame a wheel is provided for carrying and moving the element and a protrusion part spaced from the support shaft, and the first guide rail includes a groove guiding the protrusion part, a wheel bearing guide surface and a groove between said guiding groove and said guiding surface for a base 5 axle.

Advantageous further developments of the invention are set forth in the dependent claims.

The invention will now be further described with reference to the accompanying drawings, in which:

• · «· · | _ '! Figures 1 and 2 schematically show an example of balcony glazing. Such a balcony arrangement of glass elements 1 of its balcony glazing includes a guide rail 2 above the element, · · ·, 25 1, and a guide rail 4 below. · ·. 3. The guide element 5 projecting from the lower part of the element 1 is arranged to be supported,. under the guide rail 4.

The support arrangement is also particularly intended for the case where: element 1 is arranged to run on the track according to Figs. 1 and 2, 3 109226 having at least two angularly arranged guide rails 2,4.

As best shown in Figure 4, the adjacent overhead guide rails 2 form a miter joint with one another. The lower guide rails also form a miter joint with each other. In the example of Figure 4, the guide rails 2 are perpendicular to each other, but it is clear that the angle between the rails 2 can be selected freely.

As best shown in Figure 3, the carrier / transmission wheel assembly 3 comprises a vertical support shaft 6 connected to its element at its lower end and a body part 7 to which the element 1 is pivotally suspended by the support shaft 6. A wheel 8 is attached to the body part 7 for carrying and moving the element 1. The wheel 8 is connected by a horizontal axis 16 to the frame part 7 and the wheel 8 is arranged 15 to rest on a horizontal guide surface 11 arranged on a guide rail 2.

Further, the body part 7 is provided with a projection 9 arranged at a distance from the support shaft 6, preferably in the form of a pin of circular or semi-circular cross-section. The guide rail 2 has a groove for laterally guiding the projection 20 portions 9. A guide surface 11 and; between said guiding groove 10 there is further a groove 12 for the support shaft 6.

*; The frame part 7 further comprises a guide surface 13, which in the drawing example ... .. forms a straight planar surface arranged to allow the body part to rotate at an angle 17 at the junction 17 of the guide rails 2, but to prevent rotation outside the junction. The guide surface 13 is arranged to rest on the side wall 14 of the guide rail 2 which is closest to the projection. part 9.

::. 30 At a junction 17 angled to one of the guide rails 2, there is a separate plate 15 arranged at the bottom of the guide groove 10, the thickness of which is dimensioned such that • the upper surface of the plate 15 forms a load sliding surface

The suspension arrangement according to the invention operates as follows.

In Figure 4, one of the support / transmission wheel units 3 of the element 1 is shown at three different positions as it moves past the junction 17 of the guide rails 2.

5 for right-hand unit 3 moves in the direction of arrow 18 in the direction of two straight guide rail portion towards the junction 17 of the body part 7 of the guide surface 13 is supported on the guide rail 2 in the side wall 14, wherein the unit 3 maintains its orientation until the projection portion 9 collide with the first guide rail 2 as an extension of the second guide rail 2 the groove 10 in the side wall 19. In this case, the lever effect of the 10 unit 3 rotates in the direction of arrow 20 until the guide surface 13 will guide rail 2 of the side wall 14 parallel to and thus proceeds to the top of the unit 4 as shown in Figure 3 orientation.

In the solution according to the invention: 15 1. No separate pieces to be mounted on the guide rail 2 are needed 2. When the wheel unit 3 turns, no friction causing surfaces are formed, but the wheel unit rotates on the pivot pin 9.

20: ·:; 3. The pivot pin 9 may be arranged to travel with a small clearance relative to the rotator »· · 1 · [of the groove 10, whereby during pivoting it will carry the wheel unit and '; the movement of the wheel 8 is completely smooth. If necessary, the process can be enhanced * ·! .. by placing a separate plate 15 at the bottom of the groove 10, which 25 forms a sliding surface on the pivot pin 9.

, ··. Contrary to the solution shown in the drawing, the guide rail below may be: 1 ·. supporting element / carrier wheel units 3 of element 1, the upper rail being laterally guiding.
