Description

The invention relates to a guide fitting for a sliding leaf of a window or a door, with a housing attachable to the sliding wing and a relative to the housing movable slider, wherein the slider can protrude in an extended position in a guide rail of the window or the door.

Such a guide fitting is for example from the DE 20 2009 004 790 U1 known. The known guide fitting has a guide part housing and a slide element mounted slidably in the guide part housing. A spring element can be supported in the guide part housing in such a way that it pushes the sliding element out of an opening of the guide part housing, wherein a stop is formed on a side wall of the sliding element that is parallel to the pressure direction of the spring element and holds the sliding element in the guide part housing. Furthermore, a latching tongue is arranged on the sliding element, which can be latched with a locking element of the guide part housing running perpendicular to the displacement direction of the sliding element. In the known guide fitting, the sliding element is held only by the spring force of the spring element in a fully extended position. Even a relatively low pressure from above on the sliding element leads to a displacement of the sliding element. It is thus not held sufficiently secure in a fully extended position.

Object of the present invention is therefore to further form a guide fitting to the effect that the slider is securely held in an extended position.

This object is achieved according to the invention by a guide fitting for a sliding leaf of a window or a door, with a housing attachable to the sliding wing and a relative to the housing movable slider, wherein the slider can protrude in an extended position in a guide rail of the window or door and the slider has a safety stop cooperating, at least indirectly, with a corresponding safety stop of the housing to hold the slider in its fully extended position. In the guide fitting according to the invention thus the slider is not or not exclusively held by the spring force of a spring element in the fully extended position. The slider is supported in its fully extended position by the securing stops so that the slider assumes a defined extended position and holds it. This can effectively be prevented that a sliding leaf on which the guide fitting is mounted, due to an accidentally pushed back slider falls out. In addition, the guide fitting is also safe to use when no spring element is present on the guide fitting, for example, because it was forgotten in the manufacture of the guide fitting. The guide fitting according to the invention therefore meets higher safety requirements.

According to one embodiment of the invention can be provided that one of the safety stops on an elastic element, in particular a spring tongue, is arranged. This means that the safety stop is not rigidly arranged. The safety stop can be moved out of its normal position, for example by deforming the elastic element. Thus, by exerting an increased force on the sliding element, it is possible to move it past the safety stop and thus bring it into its retracted position.

Both the housing and the slider may be made of a glass fiber reinforced plastic. Thus, it is possible to inexpensively produce the guide fitting from a lightweight material, but also has sufficient stability. It is also possible to form elastic elements by the glass fiber reinforced plastic, for example as a spring tongue.

It is particularly advantageous if the securing stops have surfaces which are aligned obliquely to the vertical. Accordingly, if sufficient pressure is exerted on the slider from above, the securing stops can slide against one another, wherein at least one of the securing stops can be displaced against a restoring force. Thus, it is also possible, for example, to disassemble the wing to shift the slider targeted to a retracted position.

Furthermore, a locking device may be provided, with which the slider is fixable in a retracted position on the housing. Thus, it can be ensured that the slider assumes a defined retracted position, for example when installing a sliding leaf or when disassembling a sliding leaf, and is not displaced into the extended position, for example by a spring element which is likewise present.

A tool attack can be provided on the slider. In particular, a trough can be provided, in which a screwdriver can be attached, thereby selectively exerting a force on the slider, so that the locking is released and the slider can get into its extended position or can be spent.

On the elastic element may be arranged a detent. Thus, the elastic element can have both a safety stop and a latching nose and thus serve on the one hand to secure the sliding element in an extended position and on the other to lock in a retracted position.

At a safety stop may be followed by a sliding portion along which a detent can slide. In particular, the sliding portion is the portion along which the detent may slide after the safety stops have been released until the slider is in its lower, i.e. locked in position retracted.

Spaced away from the securing stop, a latching nose can be provided. In particular, the latching lug may be spaced from the securing stopper by the sliding portion. The locking lug can cooperate with a corresponding locking lug on the respective other part to lock the slider in its retracted position.

On the housing and on the slider each limit stops may be provided which limit movement of the slider beyond the fully extended position addition. By limiting stops thus the slider can be held captive on the housing. In addition, the fully extended position is determined by the limit stops.

At least one of the limit stops can be arranged on an elastic element, in particular a spring tongue. Furthermore, an insertion be provided on the limit stop. Thus, it is possible to construct the guide fitting in a simple manner by introducing the slider into an opening of the guide housing, whereby the limit stop is deflected and subsequently, when the limit stop of the other element has been moved past, engage behind it.

According to an alternative embodiment, a split pin can be provided, by means of which the housing and the slider can be fixed to one another in one or more relative positions. In this case, corresponding openings can be provided both in the housing and in the slider, into which the split pin can be slid in order to fix the slider and the housing in a relative position.

Particular advantages arise when the guide fitting is formed symmetrically with respect to a central plane. In particular, the safety stops, the limit stops, the sliding sections and the locking lugs can always be provided in duplicate. As a result, the reliability of the guide fitting is increased. In addition, the installation of the guide fitting simplifies since it does not have to pay attention to a special orientation of one of the parts.

A wedge may be provided which can be mounted on a fixed frame in the region of a guide rail for dismantling a sliding leaf. When moving the sliding sash of the slider is displaced by the wedge so that it passes out of the guide rail and the sliding sash can be tilted out.

In the context of the invention also falls a window or a door with a guide fitting according to the invention.

The 1 shows a sliding window 1 with a fixed frame 2 with an upper horizontal spar 3 and a lower horizontal spar 4 as well as lateral vertical beams 5 . 6 , A sliding wing 7 the sliding door 1 is at the upper horizontal rail 3 and the lower horizontal beam 4 of the fixed frame 2 in an opening direction 8th as well as in a closing direction 9 slidably guided. The guide on the upper horizontal rail 3 takes place on a guide rail, the upper horizontal spar 3 is arranged, as well as guide fittings, the upper spar 12 of the sliding sash 7 are arranged and engage in the guide rail. The sliding sash 7 is relative to a fixed field 11 slidably arranged.

The 2 shows a first embodiment of a guide fitting 20 , one on the sliding sash 7 attachable housing 21 and one relative to the housing 21 movable skid 22 having. The housing 21 has mounting holes 23 . 24 on, by which it is on the sliding wing 7 is fastened. In particular, the attachment openings 23 . 24 provided such that the housing 21 from above on the sliding sash 7 is fastened. For example, the housing 21 at a corner drive of a sliding rod fitting of the sliding sash 7 to be assembled.

The glider 22 is in the 2 shown in its fully extended position. This fully extended position is controlled by limit stops 25 . 26 defined, which also cause the slider 22 captive on the housing 21 is held. The limit stops 25 . 26 are on elastic elements 27 . 28 , in particular spring tongues arranged. To the guide fitting 20 Build together, the glider becomes 22 from the top into the housing 21 introduced. This will be the limit stops 25 . 26 displaced and then rest in the 3 Slits to see 29 . 30 on. The lower sections of the slots 29 . 30 make limit stops of the slider 22 that with the limit stops 25 . 26 interact.

As the longitudinal section of the 3 is the glider 22 in the case 21 guided. The glider 22 is supported by a spring element 31 on the housing 21 from. In particular, the spring element designed as a compression spring presses 31 the glider 22 in the fully extended position shown. In this position is the slider 22 secured. The fuse is made by securing stops on the slider 32 . 33 are provided with the appropriate safety stops 34 . 35 of the housing 21 interact. The safety stops 32 . 33 lie on the safety stops 34 . 35 on. All safety stops 32 to 35 have surfaces that are oriented obliquely to the vertical. Will on the skid 22 Force exerted, so this pressed down, so slide the surfaces of the safety stops 32 to 35 along each other, with the safety stops 34 . 35 be moved elastically outwards. This elastic movement is possible because the safety stops 34 . 35 on elastic elements 36 . 37 , in particular spring tongues, are arranged. Once the security elements 34 . 35 displaced to the outside, they slide along sliding sections 38 . 39 , Above the sliding sections 38 . 39 are latching noses 40 . 41 provided with locking lugs 42 . 43 can lock. When the locking lugs 42 . 43 with the locking lugs 40 . 41 are locked, is the slider 22 in a fully retracted position and is secured in this position by the latching.

To extend the slider 22 to enable, must with a tool on the tool attack 45 ( 2 ) are attacked to the skid 22 push upwards so far that the locking is released. The release of the locking is done in turn with displacement of the locking elements 42 . 43 outwards, which is possible because of the elastic elements 36 . 37 are arranged. The 3 can also be seen that the guide fitting 20 is symmetrical with respect to a central plane. In this case, the center plane is vertical and perpendicular to the drawing plane.

The 4 shows a wedge 50 that's a slant 51 having. Furthermore, the wedge points 50 a mounting hole 52 on. Should a sliding wing 7 must be dismantled and therefore the glider 22 can be spent in its retracted position, so the wedge 50 be mounted in the region of the guide rail, so that when a sliding of the wing from an open position to a closed position of the slider 22 along the slope 51 slides. This will make the slider 22 pressed down until it locked in its retracted position. A sliding wing 7 can now easily move around a horizontal axis from the fixed frame 2 be swung out.

The 5 shows an alternative embodiment of a guide fitting 20.1 , This guide fitting 20.1 also has a slider 22 and a housing 21 on. In this case, there are two spring elements 31 provided, which are eager to the glider 22 to push up. The glider 22 is along a central guide 60 guided. The leadership 60 has a passage opening 61 for a split pin. In the illustrated embodiment, the guide 60 integral with the housing 21 educated. The leadership 60 However, could also be designed as a guide pin, which in the housing 21 is plugged in. Such a guide pin is part of the housing 21 specific.

As the cross-sectional representation of 6 can be seen, the slider has 22 two through holes 62 . 63 on. As shown, the upper through hole 62 in alignment with the passage opening 61 is arranged, the sapwood 64 through the openings 61 . 62 be plugged and thereby the slider 22 secure in a retracted position. Will the sapwood 64 pulled out, so press the spring elements 31 the glider 22 upwards, leaving the passage opening 63 with the passage opening 61 is arranged in alignment. In this position, the sapwood 64 be used again and thereby the slider 22 Secure in an extended position. It should be mentioned that the edges of the openings 62 . 63 as well as the boundary of the passage opening 61 Represent stops over which the slider 22 indirectly (over the sapwood 64 ) can be secured in its final position.

The 7 shows a modification of the embodiment according to the 5 . 6 dar. In contrast to the embodiment of 5 . 6 points the slider 22 a slope 70 on. If the slider 22 like in the 7 Shown is extended, can be a sliding sash 7 where the guide fitting 20.2 is mounted, it can be installed that the sliding sash 7 is pivoted about a lower horizontal axis. This beats the slope 70 on the fixed frame 2 , in particular the horizontal spar 3 , and is thereby displaced down. This makes it possible for the slider 22 gets into the groove of the guide rail. Once the skid 22 is in the groove of the guide rail, it is by the spring element 31 pushed upwards, leaving the sliding sash 7 can not tip out again. The glider 22 thus works like a trap. In the extended position shown, the slider can 22 again, for example, by a split pin 64 be secured.
