Description

SPECIFICATION A fitting for the sliding light of windows, doors or the like The invention relates to a fitting for the sliding light of windows, doors orthe like consisting of wooden or plastic shaped sections corresponding to the conventional tilt and turn windows which, in the closed position, lies in a plane with at least one adjacent, preferably turning light and, for sliding, is movable initially perpendicularly and then parallel to this plane behind the adjacent light, in which respective upper and lower runners for the wheels of upper light-positioning arms, preferably forcibly actuatable by a locking rod linkage fitted in a concealed manner in the light channel, and lower guide rollers of the light can be placed on the internal face of the window frame.

Sliding light windows or doors have been known for a long time and in various embodiments. Thus, German Patent No. 17 09 307 discloses a fitting for a turn and slide light, in which a positioning device consisting of two positioning arms is arranged on the light, one of the positioning arms being hinged stationarily on the light but pivotally while the other positioning arms bear at its end near the light a bolt which is arranged movable in the light plane in a guide near the light. Moreover, the two positioning arms are connected to each other at the window frame end via a joint which, in turn, is movably arranged in a continuous groove in the window frame arranged in the plane of the window frame.

This fitting is relatively complicated and requires special shaped sections for the window frame and light frame. The same applies to the fitting for a horizontally slidable light according to German Auslegeschrift No. 17 84 710. With this known fitting, it is not possible forcibly to actuate the positioning arm for the light. In addition, the shaped section of the light frame and window frame also requires a special design in this case, substantially increasing the production costs. Furthermore, when moving the light perpendicularly to the plane of the window frame, the wheel supporting the light must pass over a gap from the window frame section into a lower positioned shaped section containing the transverse runnerforthe light.

The fitting described in more detail at the outset, on which the invention is based, is also known (cf.

"Anschlaganleitu ng" for "Abstell-Schiebebeschlag" No. 1000 of the Company Fuhr-lnfront, August 1979).

With this known fitting, positioning arms forcibly actuated by the locking rod linkage are provided on the upper edge and on the lower edge of the light so that the light can be moved parallel to itself from the closed position into a sliding position perpendicularly to the plane of the window frame. For guidance during the sliding of the light, runners are screwed on the internal face of the window frame at the top and the bottom. This known fitting is not suitable for lights which can be taken from the closed position into a tilted position for ventilation purposes. In addition, this fitting is only applicable to sliding lights which can be used in conjunction with adjacent fixed lights.Fixed lights are known to lie deeper in the window frame, while tilting or turning lights protrude beyond the internal face of the window frame into the interior, substantially complicating the sliding of an adjacent sliding light behind the tilt or turn light. Moreover, the known fitting requires considerable extra treatment for the mounting thereof, so that the advantage of being able to use conventional shaped sections for the light and window frames is substantially lost.

An object of the invention is to develop a fitting of the type described in more detail at the outset, which permits tilting of the light from the closed position into a ventilation position and also sliding of the light even when the adjacent lights themselves are turning lights, allowing the fitting to be mounted without modifying the shaped section and without significant special treatment to the shaped sections when using the wooden or plastic shaped sections conventional in tilt and turn windows. Moreover, the fitting should be equally suitable for lightweight and for large, heavy lights and should permit simple, reliable operation.

This object is achieved according to the invention in that at least two wheels with axles parallel to the plane of the light are fixed rigidly at a distance from each other on the internal face of the light frame and, in any position of the light, rest on a carriage capable of travelling on the lower runner parallel to the plane of the window frame.

A carriage, capable of travelling parallel to the plane of the window frame, for sliding lights is known per se from German Gebrauchsmuster No.

19 16 708. In this arrangement, however, the light which is merely capable of sliding, runs, when sliding, perpendicularly to the plane of the window frame only onto the carriage, so that the frame shaped sections must be of a particular type, also giving rise to problems in bridging the gap between the shaped section of the window frame and the carriage when the light moves perpendicularly to the plane of the window frame.In the new arrangement, to permit the light to rest permanently, i.e. in the closed position and in the tilted position as well as in the sliding position, on the carriage, but to permit the carriage to rest on a runner fixed or placed on the internal face of the window frame, all fitting components essential for the tilting and sliding for the lower region of the light are located outside the plane of the window frame and of the light frame so that the shaped section of both the light frame and the window frame requires no special treatment or modification in these regions. Furthermore, the light can easily be slid perpendicularly to the plane of the window frame as no gap needs to be bridged between shaped section parts. It is even possible to move heavy lights easily and smoothly from the closed position into the sliding position.Another advantage lies in the fact that the wheels serving to move the light perpendicularly to the plane of the window frame simultaneously form the tilting axis of the light in the tilted position of the light. The light can be locked in the conventional manner by means of the locking rod linkage and the central closure means for movement into the tilted position in the lower region of the light. With heavy windows, three or more than three wheels spaced apart can be provided without further ado for supporting the light during movement perpendicularly to the plane of the window frame.

In this arrangement, it is particularly advantageous if all wheels participating in the movement of the light perpendicularly to the plane of the window frame are rigidly joined together in terms of torque via a common shaft so that the movement of the light perpendicularly to the plane of the window frame can take place without distortion or twisting of the light by holding the handle of the central closure means. This is particularly important with relatively wide or heavy lights with which the traditional light twist and do not follow evenly the movement perpendicularly to the plane of the window frame when a force is introduced from one side. Independent protection is applicable to this feature.

As the runners in the lower region, like the runners in the upper region, are placed on the internal face of the window frame, the lower runner can be relatively wide in design so that the light permanently rests with its wheels on a relatively wide carriage which is therefore reliably prevented from tilting.

In this arrangement, it is advantageous if the running mechanism of the carriage has at least two supporting rollers guided at a distance from each other perpendicularly to the plane of the window frame and the wheels fixed on the light frame rest in any position of the light in the region between the guide plane of the two supporting rollers on the car riage. This ensures that the weight of the light is introduced into the carriage invariably in a region between the two supporting rollers of the carriage preventing the risk of the carriage tilting.

The light can be tilted with the aid of at least two positioning arms in an intermediate position of the locking rod linkage about the common axle of the wheels fixed on the light frame into a tilted position.

The positioning arms can be actuated forcibly by the locking rod linkage so that the tilting of the light is forciblytriggered by the central closure means.

In this arrangement, it is essential and particularly advantageous if the light is connected in each position to the upper region of the window frame by the constant engagement of the wheels at the end near the window frame of each positioning arm into the guide track parallel to the window frame plane of the upper runner which can be placed on the internal face of the window frame. This prevents the end of the positioning arms near the window frame from participating in the movement of the light perpendicularly to the plane of the window frame. Rather, the ends of the positioning arms near the window frame invariably remain in the plane of the guide track of the runner placed on top above the light on the internal face of the window frame, in spite of the concealed fitting of the positioning arms in the gap in the light.This ensures that the frame shaped section practically corresponds to the conventional shaped section of tilt and turn windows, even in this region. The shaped section merely needs slight treatment as described in more detail below.

In order, in spite of the fact that the positioning arms are fitted in a concealed manner, to allow the positioning arms to be designed in such a way that they can slide reliably past adjacent lights during the sliding of the light without interruption even if the adjacent lights themselves are turning lights, it is particularly advantageous if each positioning arm has between its ends connected to the window frame and the light frame a Z-shaped curved crosssectional region. In conjunction with the wide carriage at the lower end of the light, this ensures that the sliding light in the sliding position is located at a great distance from the plane of the window frame and can thus be slid reliably past any type of adjacent lights. Independent protection is applicable to this design.

The new design of the fitting permits a considerable reduction in the costs for such sliding lights of windows and doors. It should be noted that approximately 90% of all windows in the Federal Republic of Germany are tilt and turn windows and these and their shaped sections can be produced inexpensively and therefore in large numbers from plastic and wood. These shaped sections can be used for the frames and lights of windows and doors without significant treatment if the new fitting is used with them.

The invention is described in more detail below by an embodiment with reference to the diagrammatic drawings.

Fig. 8 shows a perspective view of a view for the better understanding of the operation of the development in Figure 7.

The window frame 1 of the window shown in Figures 1 and 2 as well as the light frames 2 and 3 consist, in the example illustrated, of mass-produced wooden shaped sections conventionally used in tilt and turn windows. The shaped sections can also be composed of plastic. It is assumed that the light 2 is a turning light which can be opened by means of the handle 4. Details of the fitting for this light are not shown as fittings for such lights are known. It is merely stated that the light 2 is located in the closed position, which also corresponds to the illustrated position of the handle 4 of the central closure means.

The closed position is designated by "I" hereinafter.

The light 3, on the other hand, is located in a venti lation position or tilted position, in which the light is tilted about a horizontal axis at the lower end of the light into the interior. The light is tilted from the closed position into the tilted position via the locking rod linkage, of which the closure pegs 6 engaging in the closure plates 7 are indicated in Figure 1, and the central closure means with an actuating lever 5. This is pivoted round about 30 from the closed position I into the ventilation position II. In this case, there are pivoted via the actuating rods of the locking rod linkage two positioning arms 12 which are arranged in a concealed manner in the upper light gap and are hinged on the one hand on the window frame, and on the other hand on the light frame. Details of them are described below.

From the tilted position the light 3 can also be released in its lower region from the window frame by continuing to turn the actuating lever 5 for the central closure means into the position Ill in Figure 2 so that it can be pulled inwards perpendicularly to the plane of the window frame, whereupon the light can be slid parallel to the plane of the window frame from the position in Figure 1 into the position in Figure 2 behind the light 2.

Two runners, that is to say an upper guide 9 and a lower runner 10 serve to guide the light 3 on the window frame. The two runners are placed, for example screwed, on the internal face of the window frame. The two runners 9 and 10 advantageously consist of continuous material which can optionally be cut to the desired length. The ends near the window frame of the two positioning arms 12 engage in the upper runner 9, the arrangement being set out in such a way that this engagement is maintained in each position of the light 3. On the lower runner 10 there runs a wide carriage 11 between the fixing and stop brackets 15, on which the lower end of the light 3 is supported in any of its positions.

The locking rod linkage has on the underside of the light locking pegs 6 which, in the closed position and in the tilted position of the light, engage in the closing plates 8 and secure the light in this position.

Only when the actuating lever 5 has been brought into the position III do the locking pegs 6 move In alignment with side windows by means of which the locking pegs can issue during movement of the lower end of the light 3 from the position in Figure 1 perpendicu larly to the plane of the window frame.

The carriage 11 consists of a profiled rail which can simply be cut to the desired length. The profiled rail is completed by two running mechanisms 28 at the ends. These running mechanisms each comprise a guiding part 29 on the front face, in which a guide track 13 for wheels for moving the lower end of the light perpendicularly to the plane of the window frame are continuously accommodated on the upper side. A web piece 31 which can be inserted into a profiled chamber 30 of the profiled rail of the slide on the front face and can be clamped in the inserted position by two clamping screws 38 (Figure 4) is rigidly connected to the guide member 29. The holding memberforthe axle of two supporting rollers 32, 33 arranged at a distance from each other is rigidly connected to the profiled web 31.Each supporting roller has a profiled circumference so that the supporting rollers are each supported on two guide ridges 34 and 35 of the lower runner 10. The runner has a rear arm with which the runner can be screwed onto the internal face of the window frame. In addition to or instead of this screwed connection, the runner can also be held simply between the stop brackets 15 which have on one side a flange for screwing them on to the window frame and on the other side a web which engages into the profiled recess 36 on the underside of the runner 10. It can be seen that the distance between the guide ridges 34,35 and corresponding to the distance between the supporting rollers 32,33 is large so that the carriage 11 rests securely and non-tiltably on the runner 10. The shaped sections which can be cut to a precise length are the essential parts of the carriage or slide and runner.

The light is supported in the guide tracks 13 of the running mechanisms 28 with respective rollers 22 which are mounted on a bearing block 20 about an axis 21 running parallel to the window frame. The bearing block surrounds the lower edge of the light and can be screwed securely on the two adjacent faces. The wheels 22 engage permanently in the guide 13, regardless of the position of the light.

Each wheel has an internal hub 25 with a recess which is flattened on one side. The ends of a rigid shaft 23 having a flattened area 24 are inserted loosely into the recesses 26 in the two hubs 25. The two wheels are connected to each other rigidly in terms of torque in this way. This enables the light to roll outwards as a whole without twisting or distortion in the guide grooves 13 whenever the light is pulled into the interior on one side, say by the handle 5.

In the mounted position, the wheels 22 and the associated parts can be covered externally by a covering plate 27.

As shown in Figures 1 and 2, the light 3 is normally pushed behind the light 2 so that it is slid laterally in only one direction from its closed position. If the light 2 is a turning light and the window frame has no mullion between the two lights, it may be desirable or necessary, in order to open or clean the light 2, to slide the light 3 forward somewhat laterally in the opposite direction, i.e. to the right in Figure 1, so that the light is free for movement. In this case, the runner 10 can have a corresponding extension to the right and a manually released stop lock which normally prevents the light 3 from sliding to the right in Figure 1, but permits such sliding by a small amount after actuation.

Figure 4 shows the lower closing plate 8 in a plane view, the three possible positions I to Illa of the locking peg 6 in the plate 8 being shown. Figure 4 also shows the fitted position of the closure plate 8. The closed position I, the tilted position II and the transverse sliding position Ill of the light 3 are also shown.

Figure 5 shows the upper region of the window in the closed position of the light 3. The groove 44 which encircles the peripheral side, is covered by the covering rail 48 and in which the actuating rods 45 of the locking rod linkage are guided are shown. Figures 4 and 5 also show the conventional profile of window frames and light frames, of the type known from the frequently used normal tilt and turn windows.

Each positioning arm 12 is hinged on one side to the light frame and is coupled to the actuating rod 45 in such a way that, during sliding of the rod 45, the positioning arm 12 can be pivoted out of the closed position in Figure 5 into the tilted or open position and back. The positioning arm is normally concealed in the light gap, as shown in Figure 5. To simplify assembly and unhingeing of the light, the positioning arm is designed in two parts, the two parts being detachably connected to each other in the region between the ends of the positioning arm, as shown in Figure 6.

The fact that each positioning arm has a crank, shown clearly in Figures 5 and 6, between its ends is an important feature. This crank is Z-shaped in cross-section. This crank guides the positioning arm outwards from its region 43 lying in the light gap and upwards to the region 41 at whose end there is arranged the wheel 40 which engages permanently, i.e. in any position of the light 3, in the straight runner 9 fixed, in particular screwed, on the internal face of the window frame. The cranked portion is designated by 42, whereas the part 43 associated with the light is cranked downwards again from the plane of connection with the other part in its longitudinal direction, and lies in the plane above the covering rail 46 at the point of connection with the actuating rod 45.The only finishing treatment needed on the profile of the light 3 is the milling out of a small recess 50, which is shown in Figures 1 and 5 and serves to receive the vertical arm 42 of the cranked part when the light is located in the closed position shown in Figure 5.

Figure 7 shows a modified embodiment. In this arrangement, a restraint 51 is provided on the runner 10 at the end lying in front of the ciosed position of the sliding light. This serves to press the lower end of the light forcibly into the closed position as the light is slid back in front of the light opening, without particular attention needing to be paid to the light.

The restraint 51 is a guide part with a curved guide groove 57 arranged on the runner 10. This guide part has an entry portion pointing in the sliding direction and a guide portion running perpendicularly to the plane of the window frame which pass into each other continuously. A downward pointing guide peg or a guide roller 56 is provided on the bearing block 52 for the wheel 22 of the light. It enters during the sliding of the slide in Figure 7 to the left into the entry portion of the restrain 57. Owing to this sliding movement, the guide roller 56 is guided in a direction perpendicular to the plane of the window frame toward the closed position. In this process, the wheel 22 rolls in its transverse guide 13 toward the closed position or toward the tilted position.As the wheel 22 at the illustrated end of the light is forcibly cou pled to the wheel or the other wheels in the region of the other end of the light via the shaft 23, the other end of the wheel is also forcibly pressed into the tilted position or closed position. It is particularly advantageous if the restraint 51 is used in common in conjunction with the rotatable forcible connection of all wheels 22 via the shaft 23.

In the example illustrated, the restraint 51 forms the normal stop for limiting sliding movement of the carriage in the position shown so that the light is located in exact alignment with the light opening in the window frame when the carriage or parts of the carriage strike the restraint 51. The adjacent, nonsliding light cannot be opened for cleaning purposes if there is no fixed mullion 11, as the sliding light would prevent the adjacent light from opening. In this case, the restraint 51 can be folded up from the position shown in Figure 7 so that the sliding light can be pushed out beyond the position in which it is aligned with the light opening in the window frame by a small amount so that the adjacent light is cleared for opening. In the folded up position, the restraint 51 also forms the limiting stop for the extended sliding movement of the sliding light.

It is also pointed out that a screw 53 on the bearing block 52 engages in a recess 54 on the front face of the slide or carriage 11 and thus prevents the light from lifting relative to the carriage. The carriage itself is prevented from lifting in that the edge of the carriage 55 engages beneath the projecting flange or web 60. It is also pointed out that Figure 7 shows the parts in a perspective exploded position, so that the parts do not engage in each other.
