Description

DESCRIPTION

Operating mechanism for a lift-up sliding door and lift-up sliding door equipped with said mechanism [0001] The present invention relates to an operating mechanism for a lift-up sliding door or window and a lift-up sliding door or window equipped with said mechanism.

[0002] A lift-up sliding door has a rectangular sheet in the form of a frame with a glass panel or the like, which is mounted in a sliding or roll-up manner on a fixed frame by means of which the lift-up sliding door is fixed in an opening of door.

[0003] In particular, the invention relates to an operating mechanism with an operating handle with which a lift-up sliding door equipped therewith can be raised and slid, for opening the lift-up sliding door and with which the lift-up sliding door can be opened. also be lowered and locked to close the lift-up sliding door.

[0004] Traditionally, such an operating mechanism uses an operating crank with a crank and a crank pin at right angles to it, rotating about a rotary axis perpendicular to the plane of a sliding frame operable with the operating crank . The operating crank itself therefore rotates in a plane parallel to the plane of the sliding frame and is connected to an operating bar which moves vertically up and down in a hardware slot and is connected to a lifting mechanism of a guide on which the sliding frame rests.

[0005] The operating mechanism as such contains a crank mechanism for converting the rotational movement of the crank pin into a translation of the operating rod as well as a guide with lifting mechanism that can be actuated with the operating rod. By moving the operating bar with the operating crank to the highest vertical position, the lift sliding door lock is unlocked and the sliding frame is raised by the lifting mechanism simultaneously, so that the underlying wheels of the guide can roll freely on or in a guide parallel to the plane of the frame, so that the sliding frame can slide freely to open or close.

[0006] When the operating bar is located in the lowest vertical position, the sliding frame rests on the fixed frame and the wheels of the underlying guide can no longer roll so that they can no longer slide.

[0007] In practice, crank rotation about an axis, perpendicular to the plane of the slide frame, will rotate from an upward position where the slide frame is lowered and locked, to a downward position where the sliding frame rises and unlocks and the sliding frame can be moved by light pressure. In this way, the crank rotates in a plane parallel to the plane of the sliding frame.

[0008] Typically, the frame is made up of hollow profiles, for example aluminum profiles, and the operating mechanism is hidden in the hollow profiles, whereby the crank mechanism and the vertical operating bar are hidden in a vertical upright of the frame sliding, while the guide with its lifting mechanism is hidden in a horizontal connection profile of the frame.

[0009] Thus, a built-in operating mechanism forms an L-shaped perpendicular construction in which the operating bar is perpendicular to the longitudinal direction of the guide, in other words, perpendicular to the running direction of the guide or, at therefore also perpendicular to the sliding direction of the sliding frame. Document EP 2141314 A1 discloses said mechanism of a sliding and lifting door.

[0010] A drawback related to this traditional operating mechanism is the orientation of the crank mechanism which transfers the rotation of the shaft via the rotation operating crank to an operating bar that moves vertically and raises or lowers it vertically.

[0011] Traditionally, the crank mechanism is oriented parallel to the plane of the sliding frame itself and is integrated into a vertical side of the sliding frame at the level of the axis of rotation of the crank and protrudes laterally in relation to the operating bar in a parallel direction to the longitudinal direction of the guide or therefore also parallel to the plane of the sliding frame. The disadvantage of this orientation is that the crank mechanism needs a wide post to hide the operating mechanism, more specifically the crank mechanism, so there is less space for the glass section and it lets in less light and the frame also gives a Less aesthetic impression due to the wide profiles of the sliding frame.

[0012] An example of a sliding door with a different orientation of the handle arrangement is described in WO 2018/130733 A1. US 2008/001413 A1 and EP 2267 253 A2 show operating mechanisms for doors or windows where the axis of rotation of the operating element is parallel to the surface of the door or window.

[0013] The purpose of the present invention is to provide a solution to the aforementioned and other disadvantages.

[0014] To this end, the invention relates to an operating mechanism for a lift-up sliding door with a sliding frame with hollow profiles, the operating mechanism comprises a guide with a lifting mechanism for raising the sliding frame and intended to be mounted on a horizontal frame profile, an operating bar which is at a right angle to the longitudinal direction of the track and is intended to be mounted on a vertical frame profile and which engages the lifting mechanism of the track for operation of the lifting mechanism lifting by a vertical translation of the operating rod and a crank mechanism with a swivel joint for rotation of an operating crank about the axis of rotation of the swivel joint whereby the crank mechanism engages the operating rod for conversion of a rotary movement of the swivel joint in a vertical translation of the operating bar, characterized by the fact that the mechanism crank mo extends in a direction perpendicular to the longitudinal direction of the guide and perpendicular to the operating rod and such that the axis of rotation of the rotary joint of the crank mechanism extends parallel to the longitudinal direction of the guide.

[0015] The crank mechanism of said operating mechanism according to the invention therefore rotates in fact a quarter turn around the longitudinal axis of the operating rod relative to the known operating mechanism.

[0016] An advantage of such an operating mechanism is that it can be integrated into a narrower vertical profile on one vertical side of the sliding frame, so that there is more space for the glass section and the frame itself has a more aesthetic appearance.

[0017] Another advantage of such an operating mechanism is that the operating handle is easier to integrate into the frame of the upright.

[0018] The vertical translation of the operating bar takes place in a hardware slot that is mounted on the vertical side of the sliding frame, or in a hardware slot that is formed by profiling inside the profile itself, which is part from the vertical side of the sliding frame.

[0019] The embodiment whereby the operating bar moves in a profile inside a vertical profile is particularly advantageous since it eliminates the need to mount an accessory with a hardware slot. The decoupling of the crank mechanism and the vertical operating bar also make it easier to choose the height of the crank more freely.

[0020] The internal profile that serves as a fitting slot, consists of two metal profiles and a third intermediate part made of plastic, which guarantees a thermal break between the side facing the outside and the side facing the inside of the frame sliding.

[0021] Preferably, the operating bar only comes into contact with the plastic inside the profile, so that no thermal bridge can form.

[0022] The operating bar itself is connected to a lifting mechanism of a guide on which the sliding frame rests. In its highest vertical position, the operating bar pushes the lifting mechanism upwards, so the sliding window rises and the guide wheels, on which the sliding window rests, can roll freely. In this position the sliding window can be moved to close or open.

[0023] In its lowest vertical position, the operating bar pushes the lifting mechanism downwards, whereby the sliding frame is lowered, and is locked in this position and the guide wheels can no longer roll. Such lifting mechanisms and guides belong to the known state of the art.

[0024] The operating bar may also serve to lock the sliding frame with an adjacent fixed or mobile frame in the closed condition. To this end, the operating bar is provided with protrusions, respectively recesses, which can cooperate with recesses, respectively protrusions, on the adjacent frame such that the two frames interlock when lowering the first frame provided with an operating crank.

[0025] This invention also relates to a lift-up sliding door that is equipped with the operating mechanism according to the invention.

[0026] The invention also relates to a lift-up sliding door with a sliding frame that has been slidably mounted on a fixed frame and is constructed of hollow profiles, whereby the frame sliding frame has an operating mechanism as described and whereby the guide is hidden in a horizontal profile of the sliding frame to support the sliding frame and whereby the operating bar connected to the crank mechanism is hidden in a vertical profile of the frame sliding.

[0027] With the intention of better showing the characteristics of the invention, some preferred embodiments of an operating mechanism for a lift-up sliding door according to the invention and a lift-up sliding door equipped with said mechanism are described below by way of example, without limitation, with reference to the attached drawings, where:

Figure 15 schematically shows a cross section of a variant embodiment of Figure 12;

Figure 16 shows an alternative mounting of an operating crank on the operating mechanism of Figure 9.

[0028] The frame 6 shown in figure 1 is a sliding rectangular frame of a lift-up sliding door 2 with a traditional operating mechanism 1 as shown in figures 3 to 5 for opening the lift-up sliding door 2 unlocking the frame 6 and sliding this frame 6 into a fixed frame (not shown) with which the lift-up sliding door 2 is installed in a door opening.

[0029] To open, frame 6 slides open in the direction of arrow O.

[0030] Figure 3 shows an operating mechanism 1 of a lift-up sliding door 2 according to the known state of the art which is provided with a rotating operating handle 3, whose axis of rotation 4 is perpendicular to the plane 5 of the lift-up sliding door 2 powered with it.

[0031] The sliding frame 6 is made up of vertical profiles 6' and horizontal profiles 6" that are hollow and in which the aforementioned operating mechanism 1 is hidden.

[0032] In the example shown in Figure 3, the operating mechanism 1 contains two connected guides 16 on which the frame 6 rests and which is provided with a lifting mechanism 16' for lifting the frame 6 in order to unlock the frame of the fixed frame and slide or roll it on the fixed frame in the direction of travel X-X' of the guides 16.

[0033] The guides 16 are hidden in the lower horizontal profile 6".

[0034] For the operation of the lifting mechanism 16', a crank mechanism 8 is provided, which is located at a certain height in a vertical profile 6', in front of an operating crank 3 and an operating bar 9 connecting the lifting mechanism crank 8 with one of the guides 16.

[0035] In this case, the operating bar 9 is slidably housed in a guide profile 9' which abuts against the profile 6'.

[0036] The crank mechanism 8 and the operating bar 9 and the guide profile 9' are hidden in a vertical profile 6'.

[0037] In the example, the operating crank 3 has a crank pin that engages through an opening in the front of the vertical profile 6' with a swivel joint 8' of the crank mechanism 8 which is provided with a 8" hole that is not round where the crank pin can fit properly.

[0038] The swivel joint 8' and the adjusting crank pin can rotate around a horizontal axis of rotation 4 perpendicular to the longitudinal direction of the guides 16 or, therefore, perpendicular to the direction of travel XX' of the guides 16 and perpendicular to the longitudinal direction YY' of the operating bar 9.

[0039] In this known embodiment, the crank mechanism 8 extends to the left of the operating bar 9 and, with the operating bar 9 coupled to it and the possible guide profile 9', has a length D measured perpendicularly to the axis of rotation 4. The crank mechanism 8 extends with its length parallel to the longitudinal direction X-X' of the guides 16.

[0040] At the level of the axis of rotation 4 of the operating crank 3, the width B of the sliding frame 6 covers the crank mechanism 8 and the operating bar 9 over the length D to convert the rotation of the axis of rotation 4 of the rotary operating crank 3 in a vertical translation of an operating bar 9 in the direction Y-Y' which connects with a guide 16 below the sliding frame 6. In view of the relatively large width of the crank mechanism 8 in a direction perpendicular to the axis of rotation 4, a profile 6' with a relatively large width B is necessary to be able to hide the crank mechanism 8 longitudinally D.

[0041] Figures 7 and 8 show a sliding frame 6 of a lift-up sliding door 1, according to the invention, with an operating mechanism 10, according to the invention, as shown in figures 9 to 11.

[0042] The operating mechanism 10 according to the invention differs mainly from the operating mechanism 1 of Figures 3 to 5 in that according to the invention, the crank mechanism 14 extends longitudinally D in a direction perpendicular to the longitudinal direction X-X' of the guides 16 and perpendicular to the longitudinal direction Y-Y' of the operating bar 15, that is, perpendicular to the X-X'/Y-Y plane, and so that the axis of rotation 12 of the rotary joint 14' of the crank mechanism 14 extends parallel to the longitudinal direction X-X' of the guides 16.

[0043] As follows from the perpendicular projection of the operating mechanism 10 in a plane extending perpendicular to the operating bar 15, the crank mechanism 14 in this case protrudes forward relative to the projected silhouette of the guides 16 and the operating bar 15.

[0044] At the level of the axis of rotation 12 of the operating crank 11, the width C of the vertical front 13 of the vertical profile 6' of the sliding frame 6 covers the crank mechanism 14 in its width E in order to convert the rotation of the axis of rotation 12 of the rotary operating crank 11 in a vertical translation of an operating bar 15 which is connected with a guide below the sliding frame 6.

[0045] The comparison of figures 6 and 13 shows that the invention allows a vertical profile 6' to be provided with a width C which is considerably smaller than the corresponding width B of a profile 6' of a known lift-up sliding door.

[0046] In this case, the operating handle 3 is fixed inside the frame 6, more specifically on the side 22 facing the glass 7 of the vertical profile 6' of the frame 6, so that the operating handle 3 is coupled through an opening on this side 22 with the swivel joint 14' of the crank mechanism 14.

[0047] As is evident from Figure 16, the operating handle 3 can alternatively also be mounted on the opposite external side 22' of the vertical profile 6'.

[0048] The cross section of Figure 12 also shows that in this case the operating bar is located behind the crank mechanism seen from a direction perpendicular to the X-X' / Y-Y' plane.

[0049] Figure 13 shows a top view of figure 9, with an operating handle mounted on the surface 13, in which the location of the operating bar 15 in the profile 6' of the sliding frame 6 is seen, as well as the location of a carriage 17, which is fixedly connected to the operating bar 15 and transfers its movement to the guide 16.

[0050] Figure 14 shows a detail indicated in Figure 13 as F15 on a larger scale, with the operating mechanism 10 according to the invention consisting of the rotating operating crank 11, whose rotation axis 12 is coupled to a mechanism 14 to convert the rotation of the axis of rotation in a vertical translation of the operating bar 15 which, by means of a carriage 17 attached to it, raises or lowers an articulated attachment 18. This articulated attachment 18 connects in an articulated manner with the underlying articulated links 19 of guide 16.

[0051] Figure 15 shows a cross section of a variant embodiment of the operating mechanism 10 according to the invention at the level of the axis of rotation 12 of the operating crank 11, whereby the structure and profile composition of the vertical side 13 of the sliding frame 6 are shown in more detail. The vertical side 13 is composed of an outer metal profile 20 and an inner metal profile 21, which are held together by two heat-insulating spacers 23, 24 made of plastic, whereby a protruding section 20' of the outer metal profile 20 , and a protruding section 21' of the internal metal profile 21, together with the heat-insulating spacer 23, form a guide for the operating bar 15 that moves vertically by means of a lifter 25 that is connected with the operating bar 25 by means of a fixed connection. .

[0052] The lifter 25 is moved by the mechanism 14 that converts the rotation of the rotary operating crank 11 into a vertical translation of the operating bar 15. The internal metal profile 20 has a latching fixing 27 that holds a seal of rubber 28 against the outer glass panel 7a. The inner glass panel 7a is also held by a rubber seal 29 which is held between the inner metal profile 21 and the glass. The outer glass panel 7a and the inner glass panel 7b of the glass section are kept apart by a gas-tight spacer 30.

[0053] The invention also relates to a lift-up sliding door 2 with a sliding frame 6 provided with an operating mechanism 10 according to one of the described embodiments in which the operating mechanism 10 is mounted on a vertical side 13 of the sliding frame 6 of the lift-up sliding door 2 and the operating bar 5 can be moved vertically on this vertical side 13 of the sliding frame 6 of the lift-up sliding door 2.

[0054] The present invention is in no way limited to the embodiments described by way of example and shown in the figures, but an operating mechanism for a lift-up sliding door according to the invention and a lift-up sliding door equipped with said mechanism can be perform in all kinds of shapes and dimensions without departing from the scope of the invention, as described in the following claims.
