Description

Accessory including a tackle with rigid lift protection

Technical Field

The present invention relates to an attachment for a slidable leaf that can be erected from a fixed frame. The invention further relates to a door or window comprising a fixed frame, a slidable leaf and such an accessory. The invention further relates to a method for assembling an accessory for a slidable leaf.

Background

DE 202009019144U 1 discloses a fitting for a leaf that can be erected from a fixed frame (abstellbar) and slid, wherein the fitting has:

a. the pulley comprises a pulley shell and a pulley;

b. a rail on which the carriage can travel, wherein the rail has a rail section for supporting the pulley and a section with a downwardly directed rail projection at least partially bridging (ü bergeifenden) the carriage.

Such a generic fitting furthermore has an upwardly directed spring element in the end section of the carriage housing, which spring element is inserted so as to be slidable, so that the play below the bridged section is reduced by the sliding movement of the spring element, so that the carriage is protected against the bridged section of the carriage rail in the inserted state of the carriage after the insertion tilting movement.

A slidable spring element is only conditionally suitable for many times withstanding high loads: this high load occurs when the leaf comes to rest against the rail limit (or stop). Furthermore, it is costly for the fitter to manipulate the slidably inserted spring element in order to fit and remove the known fitting.

Disclosure of Invention

The object of the invention is therefore to develop a fitting of this type in such a way that the skid can be mounted and dismounted on the running rails in a significantly simpler manner, wherein the skid is to have a very stable lifting protection (ausheischicherung) which is subjected to high loads several times. The object of the invention is also to provide a door or window with such a fitting. The invention is based on the object of specifying a method for assembling an accessory having a user-friendly and stable lifting protection.

The object according to the invention is achieved by a fitting having the features of claim 1, a door or window according to claim 11 and a method for assembling a fitting according to claim 12. The dependent claims delineate preferred developments.

The terms "upper", "lower", "horizontal", "vertical" and the like are selected within the scope of the invention to relate to the assembled state of the fitting.

The object according to the invention is therefore achieved by an accessory for a leaf that can be raised from a fixed frame of a door or window and can be slid. The leaf can additionally be tiltable and/or have a gap ventilation position. The accessory has a carrier that includes a carrier housing and at least one road wheel/sheave (Laufrolle). Preferably, the trolley has two or three sheaves. The carriage also has a slide rail. The slide rail has a rail portion for supporting the pulley at a lower side. Furthermore, the running rail has a section which at least partially bridges the carriage. A downwardly directed rail projection is arranged or formed on this bridging section.

In order to provide lift protection of the trolley, the trolley has an upwardly directed trolley projection according to the invention. The carriage projection is configured such that it catches (hitterreift) the slide projection when the carriage is raised to thereby prevent continued separation of the carriage from the slide. The carriage projection is configured here to be rigid (i.e. immovable) relative to the carriage housing.

In contrast to the lift protection known from the prior art, the lift protection according to the invention is arranged on the carriage housing so as to be non-slidable or non-rotatable. The carriage projection is in particular not adjustable relative to the carriage housing. The lift protection according to the invention does not have to be handled by an assembler for assembly or disassembly, so that the assembly time as well as the disassembly time of the fitting according to the invention is significantly reduced. Furthermore, the lift protection according to the invention is configured to be mechanically particularly stable and insensitive to loads. Finally, the production costs of the fitting are significantly reduced due to the particularly simple design of the lifting protection.

Preferably, the carriage projection projects upwards in the vertical direction by ± 30 °, in particular by ± 20 °, preferably by ± 10 °. This reliably ensures that the carriage can catch the rail projection when it impacts indirectly or directly against the stop of the rail.

The lift protection with the trolley projection can be constructed in the form of a component provided on the trolley housing. The lift protection device can be glued, welded, soldered, screwed, riveted to the carriage housing or latched to the carriage housing, for example. The lift protection is preferably arranged or formed in block form (or in the form of a cube) on the carriage housing. The lift protection device may have a platform which, in the assembled state of the skid, is located directly below the spanning section.

In contrast, a particularly simple and reliable construction of the lift protection device is achieved if the carriage projection is constructed in one piece with the carriage housing.

The carriage projection is particularly stable if it is constructed from metal, in particular from zinc diecasting.

The rail projection is preferably limited by a pivot radius, wherein the pivot radius is defined by the radial maximum pivot movement of the carriage below the bridging section when the carriage is being assembled or disassembled. The swing radius may intersect the outermost free end of the glide track projection. The pivot radius can be configured to be less than 2 mm, in particular less than 1.5 mm, particularly preferably less than 1 mm below the outermost tip of the rail projection. In a particularly preferred embodiment of the fitting, the skid does not have to be carefully inserted into the running rail during its assembly, but can be pivoted at any point at least partially below the bridging section of the running rail.

In a further preferred embodiment of the fitting, the carriage projection is arranged or formed in an end section of the carriage housing (in particular viewed in the direction of the longitudinal axis of the carriage). This end section of the carriage housing can be designed here in the form of a coupling section which is designed to receive a coupling rod of the fitting. The fitting may have a coupling rod for connecting the two trolleys. In this case, the end section of the carriage can be particularly easily ejected from the rail if it strikes a stop of the rail when the leaf is opened. It is therefore particularly preferred if the carriage projection is arranged or formed in at least one end section of the carriage housing.

The accessory may have a plurality of the previously described sled projections on the sled. The lift protection with the carriage projection is preferably of identical design. More preferably, a pulley projection is provided or formed in each of a plurality of end sections of the pulley housing.

The sled may have a spreader arm. The spreader arm can be arranged on the carriage housing in a pivotable manner. The spreading arm can be pivotably connected to a profile rail (profileschine) of a fitting for fastening to the leaf.

In a further preferred embodiment of the fitting, the carriage has a control arm, which is articulated on the spreading arm. The control arm may be guided in a guide groove of the trolley. The guide groove is preferably formed in the carriage housing.

The skid can have an upper ridge on the skid housing to prevent a tight stop (detent) at the fitting

) The trolley is ejected from the slide rail. The upper bulge can be formed integrally with the carriage housing. The carriage preferably has an upper bulge on the side of the carriage housing facing away from the spreading arm. The upper bulge can have a slope in order not to interfere with the pivoting-in and pivoting-out of the skid during the assembly or disassembly of the skid. The ramp is preferably formed on the side of the carriage housing facing away from the spreading arm. The upper bulge can be provided on a (in particular axial) end section of the carriage housing.

Alternatively or in addition to the upper bulge, the carriage may have a lower bulge to prevent the carriage from ejecting from the slide rail in the event of a tight stop of the fitting. The lower bulge can be formed integrally with the carriage housing. The carriage preferably has an underside elevation on the side of the carriage housing facing away from the spreader arm. The lower bulge is preferably arranged or formed between two pulleys on the carriage housing of the carriage.

The upper bulge (or lower bulge) initially contributes to the clamping of the carriage with the fitting tightly stopped. Due to the dynamic nature of the system, the carriage then finally springs back onto the rail, so that a renewed movement of the leaf by the carriage can also be achieved. The fitting can therefore also be used after the tight stop without maintenance.

The invention further relates to a door or window comprising a fixed frame and a leaf that is slidable (and in particular tiltable) relative to the fixed frame, wherein the door or window has the previously described fitting.

The object according to the invention is also achieved by a method for assembling a fitting (in particular as described herein), comprising the following method steps:

A. mounting a slide rail on a fixed frame of a door or window, wherein the slide rail has a rail portion for receiving a carriage and a bridging section for partially bridging the carriage in a mounted state;

B. placing the trolley on the rail section, wherein the trolley rests with its at least one pulley on the rail section;

C. the carriage is pivoted in such a way that the carriage projection rigidly arranged or formed on the carriage is located below the downwardly directed rail projection on the bridging section of the rail.

The method according to the invention for fitting a fitting can be carried out particularly simply for the fitter, since no movable parts are required for handling the lifting protection device during fitting of the carriage.

Detailed Description

Fig. 1 shows a door 10, the door 10 comprising a fixed frame 12 and a leaf 14 movable relative to the fixed frame 12. The leaf 14 is supported on the fixed frame 12 by means of fittings 16.

The leaf 14 can stand (in particular parallel) from the fixed frame 12 and can be opened along an opening direction 18. Additionally to this, the leaf 14 can (as in the case of the present invention) be tiltable.

A grip 20 is provided on the leaf 14. If the grip 20 is in the closed position 20a, the leaf 14 can be locked on the fixed frame 12 by means of a non-illustrated, slidable transmission lever. If the grip 20 is in the open position 20b, the leaf 14 can stand from the fixed frame 12 and can slide along the opening direction 18. The leaf 14 can be tilted if the grip 20 is in the tilted position 20 c. The function of the various positions of the grip can also be designed differently. Furthermore, the tip position can also be configured as a gap-open position or can also be completely omitted.

The sliding movement of the leaf 14 in the opening direction 18 is effected by means of at least one carriage (here by means of a first carriage 22 and a second carriage 24). The carriages (or carriages 22, 24) each have at least one

pulley

26a, 26b, 26c, 26 d. The trolley (or these trolleys 22, 24) slides on the slide 28.

Stops 30 may be provided on the fixed frame 12, in particular on the slide rails 28, for indirectly or directly limiting the movement of the trolley (or these trolleys 22, 24). If the leaf 14 is opened with great force and impacts on the stop 30 itself and/or by means of a carriage (here by means of the second carriage 24), a derailment of one carriage 22, 24 (or of several carriages 22, 24) may result. The object of the invention is to prevent such derailment in a simple and reliable manner.

Fig. 2 shows a portion of the previously described embodiment of the fitting 16. The fitting 16 has a first head block 22. The first carriage 22 has a carriage housing 32 (here made of metal, in particular zinc diecast).

Shafts

34a, 34b are provided on the pulley housing 32 for supporting the

pulleys

26a, 26b (see fig. 1). The first carriage 22 furthermore has a spreading arm 36a which is pivotably arranged on the carriage housing 32. The spreader arm 36a is hinged at one end to the carriage housing 32 and at the other end to the profile rail 38, either indirectly or directly. The profile rail 38 can be fastened to the leaf 14 (see fig. 1).

The sled housing 32 has a guide slot 40. The control arm 42 is guided at one end indirectly or directly in the guide groove 40 and is hinged at the other end indirectly or directly to the spreader arm 36 a.

In order to prevent the first carriage 22 from derailing from the slide rail 28 (see fig. 1), the first carriage 22 has a lift guard 44 a. A lift protection device 44a is arranged or formed on that side of the first carriage 22 which faces away from the spreader arm 36 a. In the present case, the lift protection device 44a is constructed integrally (i.e. in one piece) with the carriage housing 32. A lift guard 44a is set in the end section of the trolley housing 32.

Fig. 3 shows the fitting 16 according to fig. 2 with the first carriage 22 after it has been mounted on the slide rail 28. The slide rail 28 has a rail portion 46, and the pulley 26a rolls on the rail portion 46. At the other end, the slide rail 28 has a bridging section 48. A rail projection 50 is provided on the bridging section 48 (in particular on the free end of the bridging section 48). The rail projection 50 extends downward at ± 30 ° vertically, in particular ± 20 ° vertically, preferably ± 10 ° vertically. The slide rail 28 is in the present case of one-piece construction.

The lift guard 44a extends in particular with the overhanging section 52 horizontally in the direction of the vertical section 53 of the slide rail 28. The overhanging section 52 here preferably extends from the spreader arm 36 a. The lift guard 44a has a trolley projection 54, which trolley projection 54 extends upwardly. In the case where the first head block 22 is vertically lifted, the block protrusion 54 hooks the rail protrusion 50 to prevent the first head block 22 from derailing from the rail 28. This hooking of the rail projection 50 also prevents the first block 22 from moving horizontally with the leaf 14 erected (see fig. 1) due to the misaligned center of gravity.

Preferably, the vertical gap S between the upper side of the carriage projection 54 and the lower side of the bridged section 48 does not exceed the vertical pulley height H between the lowermost side of the pulley 26a and the upper side of the rail part 46. Alternatively or additionally to this, the vertical gap S is preferably configured to be less than 2.5 mm, in particular less than 2 mm, particularly preferably less than 1.5 mm.

The side (Flanke)56 of the carriage lug 54 facing away from the vertical portion 53 of the running rail 28 is directed at the running rail lug 50 at an angle α of between 60 ° and 90 °, in particular between 70 ° and 90 °, preferably between 80 ° and 90 °, relative to the horizontal, whereby a particularly secure hooking of the carriage lug 54 to the running rail lug 50 is achieved, the lift protection device 44a preferably has a platform 58, which platform 58 adjoins the side 56, the platform 58 is preferably designed horizontally ± 30 °, in particular horizontally ± 20 °, particularly preferably horizontally ± 10 °, the vertical spacing between the platform 58 and the underside of the running rail lug 50 particularly preferably does not exceed the vertical pulley height h between the lowermost side of the pulley 26a and the upper side of the rail portion 46, alternatively or additionally to this, the vertical spacing between the platform 58 and the underside of the running rail lug 50 is preferably designed to be less than 5 mm, in particular less than 4 mm, particularly preferably less than 3.5 mm.

In a particularly preferred embodiment of the invention, a) the vertical gap S between the upper side of the carriage projection 54 and the underside of the bridging section 48 and/or b) the vertical spacing between the platform 58 and the underside of the rail projection 50 is configured to be smaller than the vertical pulley height H between the lowermost side of the pulley 26a and the upper side of the rail part 46.

In order to be able to pivot the first carriage 22 in the direction of the arrow 60 onto the running rail 28 (in particular vertically aligned onto the rail part 46) during assembly of the first carriage 22, the running rail projection 50 is formed above the pivot radius 62. The carriage projection 54 can be adapted to the rail projection 50 in such a way that, if the carriage projection 54 is swung past the rail projection 50, there is a spacing of less than 2 mm, in particular less than 1.5 mm, particularly preferably less than 1 mm or less than 0.5 mm between the rail projection 50 and the carriage projection 54. The carriage projection 54 can be adapted to the rail projection 50 in such a way that the carriage projection 54 just strikes (streift) the rail projection 50 when the first carriage 22 is pivoted in. The carriage projection 54 preferably has a ramp 64 on its upper side, which ramp 64 follows the pivot radius 62 (linearly or circularly). The side 56 may be aligned with a vertical side 65 of the sled housing 32, the vertical side 65 facing the vertical portion 53 of the slide rail 28.

Fig. 4 shows a further embodiment of the fitting 16. The fitting 16 has a first head block 22 and a second head block 22 a. The second carriage 22a has in particular (in comparison to the first carriage 22) no control arm 42. The second carriage 22a is articulated indirectly or directly to the profile rail 38 via the spreader arm 36 b. In this case, the first carriage 22 is articulated indirectly or directly on the same profile rail 38 via the spreader arm 36 a. The unit shown in the figures, which is composed of the first carriage 22, the second carriage 22a and the common profile rail 38, represents a double carriage 67 or double carriage.

The first head block 22 is connected to the second head block 22a via a coupling rod 66 a. The second carriage 22a is connected via a further coupling rod 66b to a further carriage (in particular in the form of a further double carriage), not shown. The first carriage 22 has a lift protection device 44a in the connection region of the coupling rod 66 a. In a further preferred embodiment, the first carriage 22 can have a further lift protection (not shown; designated by reference numeral 68 in fig. 4) in the region of the guide groove 40. The second carriage 22a has a

lift protection

44b, 44c in at least one end section, preferably in the region of both end sections as shown in fig. 4. The lift guards 44b, 44c are in the present case set on the second head block 22a in the region of the connection of the

Fig. 5 shows a further embodiment of the fitting 16 with the carriage 22. The sled 22 is preferably a sled on the side of the grip, i.e., proximate the grip 20 (see fig. 1). The carriage 22 corresponds to the carriage 22 according to fig. 2 to 4. The carriage 22 according to fig. 5, however, has an upper bulge 70 on the upper side of its carriage housing 32. Furthermore, the lift guard 44a is shortened in the longitudinal direction of the skid 22 compared to the lift guard 44a according to fig. 2 to 4. The configuration or arrangement of the upper side ridge 70 and the lift guard 44a can be implemented independently of each other.

Fig. 6 shows the structure of the carriage 22 in the region of the upper bulge 70. The upper bulge 70 is rigidly formed or arranged on the carriage housing 32. In other words, the upper bulge 70 is not movably (in particular, non-slidably and non-rotatably) formed or arranged on the carriage housing 32. Particularly preferably, the upper bulge 70 is formed integrally with the carriage housing 32. The upper ridge 70 may have a ramp 72 to simplify the swinging in and out of the sled 22 during assembly or disassembly thereof. The ramp 72 is formed here on the side facing away from the spreader arm 36a (see fig. 5). The upper ridges 70 of the trolley 22 prevent ejection from the slide rails 28 (see fig. 3), thereby improving the protection of the lift protectors 44a-44c (see fig. 4).

Fig. 7 shows the arrangement of the skid 22 in the region of the lifting protection 44 a. The lift guard 44a has a trolley projection 54. Block-shaped ground of pulley lug 54

Fig. 9 shows the carriage 22 in the region of the lower bulge 74. The lower ridge 74 is wedge-shaped. Alternatively or additionally thereto, the lower bulge 74 may extend in the longitudinal direction of the skid 22. The lower ridge 74 is preferably located on the side of the sled housing 32 facing away from the spreader arm 36a (see fig. 8). The lower ridge 74 prevents the carriage 22 from ejecting from the track 28 (see fig. 3), thereby improving the protection of the lift guards 44a-44c (see fig. 4). The lower raised portion 74 may be provided alternatively or in addition to the upper raised portion 70 (see fig. 6). The maximum protection is achieved by the combination of the lower ridge 74 and the upper ridge 70.

Fig. 10 shows the fitting 16 according to fig. 5 to 9.

Fig. 11 shows the fitting 16 according to fig. 10 with a lower bulge 74 in the lower region.

Fig. 12 shows the fitting 16 according to fig. 10 with an upper lifting protection 44a in the upper region. Based on the overview of fig. 10 to 12, it is clearly apparent that the lower bulge 74 (alternatively or in addition to the upper bulge 70 according to fig. 6) prevents the carriage 22 from springing out between the rail portion 46 and the bridged section 48 in the event of a hard stop of the carriage 22, without making the assembly and disassembly of the carriage 22 difficult, wherein the carriage 22 is pivoted about the rail portion 46 for the purpose of assembly and disassembly.
