Description

The invention relates to a guide device for a sliding leaf according to the preamble of patent claim 1.

Such a guide device for a sliding leaf is from the DE 20 2004 015 416 U1 already known. The known guide device comprises a base part with a U-shaped cross-section, the legs of which are designed semicircular seen in side view and have a different thickness. In the central region of the guide device side jaws are provided for lateral support of the running in the guide device sliding leaf, which are plugged into associated receptacles of the side legs. In a hollow cylindrical receptacle of the thin leg is a cylindrical side jaw and in the thick leg is an oval, one-sided flattened side jaw used projecting from her leg in the clear receiving cross-section of the base and should create possible backlash to the facing broadside of the sash ,

In order to allow an adaptation of the guide device to different thickness sliding sash, the larger side jaw can exchange or take out of their recording and then put in a turn position again in their recording. The cooperating parts must be made very dimensionally stable in this guide device and the assembly of the guide device must be done with great precision. In addition, it can easily come with the assembly of the guide device with different side jaws to assembly errors, especially if the differences between the replaceable side jaws are small.

From the DE 102 28 874 A1 Furthermore, a guide device for sliding sash is known which comprises a base part with a U-shaped cross-section and a fork-shaped, round insert part, which can be inserted in two different rotational positions in a receiving bore in the middle leg of the base part. The round insert protrudes with its forks in both rotational positions differently far into the space between the lateral legs of the base part, so that two different widths passages for sliding panels of different thickness can be created. As a result of the rotational adjustment of the insert in the base part of the angle of the forks to the sliding panel level changes, so that in both rotational positions not the same good lateral support of the sliding leaf can be done on the side cheeks formed by the forks. Also, the supporting surfaces of the forks can not be exactly opposite each other in both rotational positions, which may be disadvantageous in view of the technical function of the guide device.

The object of the invention is to provide a guide device for a sliding sash according to the preamble of claim 1, which can be assembled in a short time with high precision and low risk of error.

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

Advantageous embodiments and further developments of the invention are specified in the dependent claims.

The stepless adjustment of the side jaw spacing ensures that the guide device can be adapted exactly to the thickness of the encompassed edge region of the sliding leaf and the tolerance position resulting from the installation situation of the sliding leaf.

The exact adjustment of the side jaw spacing is facilitated if both side jaws of the guide device displaced and by an adjustment can be adjusted. Both side jaws can be advantageously adjusted by a separate adjustment.

As adjustment means for elements of the guide device adjusting screws are particularly suitable because they produce depending on their thread pitch angle dependent on a defined feed and are obvious to use.

In combination with adjusting screws embodiments of the guide device are useful in which the side jaws are guided linearly sliding. If the displacement of the side jaws thereby transversely to the longitudinal axis of the device, the side jaws can also maintain their exact opposite position on the adjustment, which is also in view of the needs-based design of the support surfaces of advantage.

A good alternative to this is an embodiment in which the side jaws are pivotally mounted on a base part.

Regardless of their movement when adjusting it is advantageous if the side jaws are made of wear-resistant plastic. Such plastic jaws allow low-noise and low-maintenance operation of the guide device and have good damping properties, which is especially important for sliding blades made of mineral glass.

In order to bring parallel to several advantageous material properties for deployment, the side jaws made of plastic in a housing made of cast metal z. B. aluminum die casting used.

Thus, regardless of the drive movement direction, a smooth running of the sliding leaf can be ensured in the guide means, the opposing support surfaces of the side jaws are preferably designed mirror-inverted and rounded over its length or evenly curved.

A particularly cost-effective embodiment is obtained when the side jaws and a base part connecting them are integrally formed from plastic, wherein a simple pivotal displacement of the side jaws on adjusting screws remains possible.

An embodiment of the guide device can be adjusted particularly easily and in a simple manner if the side jaws are displaced via two aligned threaded pins in their guide.

In another embodiment, which is characterized by a simple construction, the side jaws are each combined with a part of the guide, wherein the guide parts together form the base of the guide device. The determination of the set jaw spacing can be made if necessary by simply tightening the mounting screws for the guide device.

Below, three embodiments of the guide device according to the invention are illustrated and described in more detail with reference to drawings.

In Fig. 1 a guide device 20 is shown, the linear guide a corresponding sliding leaf of a sliding door not shown in the entirety and should support laterally. For this purpose, a generally U-shaped base cross section having guide device 20 is mounted such that the plane of movement of the sliding leaf through the hollow fork cross section of the guide device 20 extends. Usually, the sliding panels of such sliding doors run in a manner arranged along the upper edge region of the sliding door guides and their lower edge side is guided and supported by at least one guide device 20, which is firmly screwed on the floor or fixed in other ways stable but releasably secured. For guidance and support, the guide device 20 has two side jaws 21 and 21 ', the support surface of the facing broad side of the sliding leaf opposite each other at a very small distance. The lateral support surfaces of the side jaws 21 and 21 'are correspondingly curved and mirror-symmetrically arranged in a cylinder section, whereby only in the center of the support surface and in the central transverse plane of the guide device 20 can come to a substantially linear contact with the sliding leaf. By these cylindrical support surfaces small angular deviations between the central longitudinal axis of the guide device 20 and the sliding plane of the sliding leaf can be easily absorbed or compensated.

As associated with those of the embodiment Fig. 2 and Fig. 3 can be seen, the distance between the corresponding side jaws 21 and 21 'change, wherein in the sectional view to Fig. 2 of the Edge region of a sliding sash S is drawn with a thickness that the maximum distance A max. corresponds while in Fig. 3 the minimum distance of the side jaws 21 and 21 'from each other with A min is located. Between these end positions is the adjustment of the guide device 20, within which the distance of the side jaws 21 and 21 'is infinitely adjustable.

To make this possible, the side jaws 21 and 21 ', which are made of plastic here, in a housing-like receiving support member 22 made of aluminum slide linearly guided. This in Fig. 4 in a single view visible support member 22 has the U-shaped base cross-section of the guide device 20 and includes a bottom plate 20.1 and side legs 20.2 and 20.2 ', which protrude laterally at right angles from the bottom plate 20.1. In the inner sides of the side legs 20.2 and 20.2 'are for guiding the side jaws 21 and 21' rectangular recesses 23 bzw.23 'inserted, which are adapted to the peripheral contour of the side jaws 21 and 21'. These recesses 23 and 23 'extend under wedge-shaped widening through the bottom plate 20.1 of the support component 22, so that the bottom plate 20.1 is completely penetrated in the middle region by a trapezoidal opening. In the closed end regions, the bottom plate 20.1 is provided with two screw holes 24 and 24 ', whereby the screw hole 24' is designed as a slot for easier positioning of the device. In principle, however, both screw holes 24 and 24 'could be formed as round holes or as elongated holes. It is important, however, that the screw holes 24 and 24 'are formed as countersunk holes, in which the heads associated countersunk screws can be largely submerged. Once the support member 22 is screwed with its bottom plate 20.1 on a counter surface of a floor or the like., The bottom plate 20.1 of the support member 22 is closed at its bottom, so that in the bottom plate 20.1 a dovetailed hollow cross section is present. In this hollow cross-section snugly engages a provided by the cylindrical support surface legs 21.1 and 21.1 'of the respective side jaw 21 and 21' projecting at right angles guide shaft 21.2 and 21.2 ', so that the side jaws 21 and 21'in their mounting position transverse to Longitudinal center plane of the guide device 20 in one Swallowtail guide running. The details of the mirror-symmetrical side jaws 21 and 21 'are in connection with the individual representations of the side jaw 21 in Fig. 5 to recognize more clearly.

The guide shafts 21.2 and 21.2 'of the side jaws 21 and 21' are centrally each provided with a threaded bore 27 and 27 ', in each of which a set screw is screwed as an adjusting screw 25 and 25' with matching external thread. The two adjusting screws 25 and 25 'are geometrically arranged coaxially immediately one behind the other and are based with their ends facing away from each other on the opposite wall of the associated side leg 20.2 and 20.2' of the support member 22 from. The adjusting screws 25 and 25 'also each have centrally on their side legs 20.2 and 20.2' facing the end of a Einsteckvertiefung for a turning tool such as a screwdriver or an Allen key. So that this insertion recess for adjusting the side jaws 21 is accessible by means of a rotary tool, the side legs 20.2 and 20.2 'of the support member 22 at the appropriate location with a through opening 26 and 26' provided, whose diameter is significantly smaller than the diameter of the adjusting screw 25th or 25 'itself. As a result, the axial support of the screw ends on the associated side legs 20.2 and 20.2' of the support member 22 is reliably maintained. Since a structurally determined difference in length between the adjusting screw 25 or 25 'and the guide shaft 21.2 or 21.2' of the side jaw 21 or 21 'passes through it, each of the two side jaws 21 or 21' can be adjusted individually within the scope of the possible adjustment range Adjust axially, so that effortlessly a very precise adjustment of the jaw distance can be made with lateral adjustment to the plane of movement of the sash S.

A structurally much simpler embodiment is in the Fig. 6 to 9 to see, wherein the guide device 30 integrally as a self-supporting plastic body z. B. is formed of Teflon. This plastic body comprises two side jaws 31 and 31 ', which integrally via a base member 32 arranged therebetween sprayed or poured. The base part 32 has an elongated rectangular shape and on the lateral narrow sides of the side jaws 31 are connected. After the molding of the plastic body, the side jaws 31 are initially in the tool position, ie as they are removed from the mold, at right angles from the parallelepiped base part high, as in Fig. 7 you can see.

In order to enable guidance or lateral support of the sliding leaf S ', the side jaws 31 and 31' can be displaced relative to their base part 32 in such a way that they lie against the adjustment area of the guiding device 30 with an upper, inner edge zone on the sliding leaf S '. like out Fig. 6 is apparent. The lateral displacement of the upper edge zone is due to the fact that the side jaws 31 and 31 'are pivoted about a bending axis that runs along the narrow sides of the base part 32. This results in a nearly punctiform support surface on the sliding leaf S ', since the upper edge zone is curved over its length and its cross-section accordingly, as in Fig. 6 combined with Fig. 8 good to see.

A structurally precisely defined bending axis results from the fact that the side jaws 31 and 31 'are each weakened in the transition region to the base part 32 by forming a hinge web 33 or 33'. This weakening is caused by wedge-shaped cuts, which extend along the corner areas between the base part 32 and the two side jaws 31 and 31 'and reduce the wall thickness of the side jaws 31 and 31' in this area to about half. Due to the stability of the hinge web 33 or 33 ', sufficient supporting forces can be transmitted to the base part 32 for the present application.

The bending stiffness of the parallelepiped base part 32 itself is also further increased when it is screwed in its surface-mounted mounting position on a counter surface of a floor or the like., Since it can no longer deform freely. For this purpose, the base part 32 in its end regions in each case a screw hole 34 for a countersunk screw, not shown.

For a sensitive and accurate setting of the side bake slope are provided as adjusting screws 35 and 35 ', the countersunk screws shown. These adjusting screws 35 and 35 'are passed through associated countersunk holes 37 and 37' in the base part 32, which emanate from the bottom of the plate forming the base part 32 and first open into the immediately adjacent recess adjacent to the associated hinge web 33 and 33 ', respectively. In the in Fig. 7 shown tool position of the guide device 30 can be seen that the sink holes 37 and 37 'continue following the incision as aligned threaded bores 36 and 36', which extend within their side jaw 31 and 31 '. The distance between the threaded bores 36 and 36 'from each other increases with increasing distance to the base part 32. The central longitudinal axes of the threaded bores 36 and 36' in each case with the longitudinal center plane of the guide device 30 an angle of about 18 degrees, as indicated by the in Fig. 7 drawn angle alpha is clarified. Consequently, the rotational axes of the adjusting screws 35 or 35 'screwed into the threaded bores 36 and 36' initially also run at this angle alpha. If these initially oriented obliquely adjusting screws 35 and 35 'but tightened so far that their screw head on the wall of the counterbore 37 and 37' comes into abutment, the axial force of the adjusting screws 35 and 35 'acts as a bending force, through which the side jaws 31st or 31 'are bent around their hinge web 33 or 33'. As a result, the rounded support surfaces in the upper edge region of the side jaws 31 and 31 'move toward each other until they are in their laterally supporting the sliding side S position Fig. 6 have taken. Since the conical depressions in the base part 32 are slightly oversized, the screw heads shift slightly in their countersunk holes 37 and 37 '.

If the adjusting screws 35 and 35 'are rotated in the loosening direction, the obliquely inclined side jaw 31 aligns with the release advance of the adjusting screw 35 again. By turning the side jaw 31 or 31 'belonging adjusting screw 35 or 35' can be the side jaws 31 and 31 'thus adjusted separately in their side slope to find the desired support position.

In order to avoid disadvantages in terms of the overall height of the guide device, the adjusting screws 35 and 35 'are arranged laterally next to the maximum engagement cross section of the sliding leaf S'.
Thus, the support effect of the side jaws is not affected by torsions or warping of the side jaws 31 and 31 'itself, each side jaw 31 and 31' as many, preferably two, parallel acting adjusting screws 35 and 35 'assigned. These adjusting screws 35 and 35 'should be as evenly screwed into their threaded bore 36 and 36'. Also with this guide device 30 can be the side jaws 31 and 31 ', individually adjusted laterally in the context of their constructive adjustment range.

In Fig. 10 is shown as a third embodiment, a guide device 40, which is also characterized by a simple design. The simple construction is due to the fact that here are the side jaws 41 and 41 'formed as a supporting side legs of the guide device 40 and each rigidly connected in the lower edge region with a base plate, wherein a parallelepiped basic shape having base plates as collapsible guide plates 42 and 43 are formed. The longer guide plate 43 has in its two end regions in each case a screw hole 44 with a conical countersink, through which the guide plate 43 is bolted via suitable countersunk screws 45 on the support surface of a floor or the like. The guide plates 42 and 43 are slidably mounted on a dovetail guide 46 parallel to the central transverse axis of the guide device 40 together, the front and rear narrow side of the shorter guide plate 42 are tapered so that they fit with little play largely positive fit in the laterally visible hollow cross section of the guide plate 43 , In principle, it would be conceivable to provide a possibility for screw adjustment even with this guide device 40, through which the guide plates 42 and 43 along the dovetail guide 46 can be moved relative to each other. For further technical simplification, however, it is provided to make the shift adjustment by corresponding displacement of the guide plates 42 and / or 43 and to fix only their set end position via clamping forces. The fixation can be done via the axial biasing force of the countersunk screws 45 when tightening the same when the guide plate 42 is dimensioned slightly thicker than the guide plate 43. The support surfaces of the side jaws 41 are curved in this embodiment along its length with a large radius, whereby the hollow channel between they are somewhat narrowed toward the center and in this area, the lateral support forces are exerted on the sliding sash, not shown. In the area of these support surfaces here inserts 47 are used made of plastic, which should take over the support function, wherein the device is otherwise an aluminum casting.

Alternatively, it would also be conceivable, the guide device 40 a total of a suitable plastic such. B. Teflon, so that the inserts 47 could be omitted.

In the guide device 40, a setting range between 8 mm and 13.5 mm can easily be provided, over which the device is infinitely adjustable.

This guide device 40 includes only a few items, can be produced very inexpensively and requires little installation space.

All described guide devices 20, 30 and 40 have in common that their continuous adjustment is sufficient to adapt to the different thickness of the sliding sash of conventional glass doors. When using a universal because of the infinitely variable adjustment embodiment can be achieved by standardization on the one hand and by reducing the assembly time on the other hand, if necessary, significant cost savings.
