EP1876319B1 - Sliding guide for sliding wings or wings movable into a parallel plane - Google Patents

Description

The invention relates to a sliding guide for sliding or Abstellschiebeflügel of windows, doors or the like. In such laterally movable (movable) wings, are on the frame or the like. Fixed guide rails, especially for the upper portion of the wing, provided with these over one or more extension arms is connected, which is connected via a hinge pin with a slidable in the guide rail slide.

In known sliding guides a relatively long or high hinge pin is required, which is attached to the end of the stay and then from below through the longitudinal groove (the longitudinal gap) of the guide rail in engagement with the slider already arranged in the guide rail must be brought, which is a strong bending the Ausstellarmes down requires, if the extension arm in the region of its attachment is not provided from the outset with a relatively large game, see. DE 35 40 347 C1 (Carl Fuhr ), there in particular Figures 3 . 4 with the long hinge pin 19 on the extension arm 18th

Another disadvantage of known designs is that in these the guide piece requires several internal components for locking the hinge pin with the slider. These components must be sized in width so that they do not fall through the longitudinal groove (the longitudinal gap) in the event of destruction of - possibly made of plastic - slider, but remain in the guide rail to hold the wing in this emergency. These components are mostly made of steel. The whole thing requires a correspondingly complex installation. In addition, the hinge pin is attached to the extension arm by rivets or the like., See. De 35 40 347 C1 (Carl Fuhr), there column 3, lines 30 to 47, in particular lines 37/38.

In these known cases are in the tilt position of the wing, the necessary Entkupplungsschritte (the triggering), which are required for the dismantling of the wing, visible from the outside and thus for unauthorized persons.

It is an object of the invention to provide a sliding guide, in particular for the top of the wing, in which the disadvantages are avoided and which is characterized by a simpler structure and a lighter assembly process.

This object is achieved by a sliding guide with the features of claim 1.

In this solution, the hinge pin is not permanently connected to the end of the stay arm (fixed), e.g. riveted. Rather, it is first preassembled with the slider to a unit, which is then inserted into the guide rail, whereupon the hinge pin is detachably connected to the end of the stay-arm.

The hinge pin can be made correspondingly shorter, which requires only a slight downward bending of the extension arm for its connection to the bolt.

A particularly simple, low-friction and low-noise design results according to claim 3 in conjunction with claim 1 or claim 7.

After connecting the slider with the extension of this can be partially or completely provided with a cover. Hereby, visible to the room interior visible fittings can be covered, but especially the coupling point are covered. The visible in the known systems in tilt position of the wing from the outside triggering is thus no longer visible.

Further details and advantages will become apparent from the following description of an embodiment shown in FIGS. Show it:

FIG. 1:

in side view, a sliding guide for the top of a wing;

FIG. 3:

a cross section along the section plane XX of FIG. 1 through the in FIG. 2 represented unit;

FIG. 4:

Parts of the sliding guide in perspective view before their assembly;

FIG. 5:

an enlarged view of the slider 4, without rail 1, after assembly.

FIG. 1 shows parts of the sliding guide of an example in the assembled state and in the closed position (the wing, not shown). The associated guide rail 1 is shown in side view, as well as below this extension arm 3, whose right end is attached to the top of the associated wing in a known manner. The wing is not shown. At the left end of the stay arm 3, a portion of the lower end of a hinge pin 2 can be seen. Furthermore, in FIG. 1 the horizontal sectional plane YY of the representation of FIG. 2 and the vertical section plane XX of FIG. 3 located.

The sliding guide or the arm 8 can be covered as a whole against view from the interior by a cap member 10, the hinge pin 2 with a corresponding recess 10a FIG. 4 embraces. Thus, even in the tilted position of the wing of the trip path of the unit from the outside is no longer visible. The uncovered inner arm 8 will be explained below without the cap member 10 in its function.

How better from the representations of Figures 3 and 4 can be seen, the guide rail 1 on the underside a continuous gap 1a over its length from a width, which has sufficient clearance for the migrating during operation hinge pin 2. The gap is delimited by profiled edge regions 1b and 1c, which at the same time serve as slide rails for the sliding piece 4, which moves in the interior of the guide rail in a manner that is smooth and quiet. Also, the inner cavity (as a groove or longitudinal gap) of the rail 1 limiting walls are profiled and thus form inner guides for the slider. This is also called "inner channel".

The slider 4 is integrally formed in a preferred embodiment of a plastic injection molding. It shows how the FIGS. 2 and 3 and 5 show, inside a central seat 5 for the hinge pin 2 on (short: bolt 2). In this seat, the hinge pin passes in a very simple manner. In alignment with the seat 5, the slider on one of its side surfaces on an insertion opening for the bolt, which is freely accessible, as long as the slider is not yet threaded into the guide rail.

The insertion opening has different areas of different width. This can be done by hand in FIG. 4 and 5 understand most clearly recognizable embodiment of the hinge pin 2, which is preferably made of steel.

The bolt has a head 2a with a diameter which is greater than the width of the gap 1a on the underside of the guide rail 1. The head secures the connection of the bolt with the guide rail in the event of destruction of the slider 4. Under the head of the bolt has a shank portion 2b of narrower diameter, which extends in the operating position to below the bottom of the guide rail. The width of the corresponding areas of the lateral opening of the slider 4 is matched to the corresponding areas (sections) of the bolt 2.

It is particularly advantageous that in the area for the shank portion 2b, the lateral insertion opening is delimited by two arm-shaped wing sections 6a and 6b which are partially separated by slits 7 from the body of the slider 4.

Out FIGS. 2 and 5 it can be seen that the width of the opening defined by them is smaller than the diameter of the shaft 2b. Since the wing sections can deflect elastically, there is no difficulty to introduce the hinge pin through the lateral opening of the slider in its central seating position in which the wing sections 6a and 6b tightly enclose and secure the shaft 2b by significantly more than half the particular circumference. In this case, the inner surface of the wing portions may, if necessary, downwardly be formed conically widening to prevent tilting of the slider by the obliquely positioned pin at tilting wings.

After assembly of the consisting of only two parts sliding unit from pin 2 and slider 4, this unit can be inserted from the open end into the guide rail 1 and only then the bolt with the end of the stay arm 3 are connected.

For this purpose, the projecting out of the rail portion of the hinge pin 2, first a shoulder 2c for resting on the top of the Ausstellarmes 8 and under the shoulder a cylindrical coupling portion 2d with a securing groove 2e. The coupling portion 2d is inserted from above into the receptacle 8a to the support of the shoulder 2c and secured by means of a spring element 9 engaging in the groove 2e.

Due to the few, very precisely tunable parts an almost backlash-free gliding is ensured without, for example, rattling noises. Also, the sliding guide without special skills quickly and easily to assemble.
