Description

The present invention relates to a fitting arrangement for sliding elements with sliding wing, in particular for sliding door or sliding window elements. Furthermore, the application is directed to a sliding element with such a fitting arrangement.

Sliding elements with sliding wings are known, for example, as hand-operated terrace or balcony doors or as windows. Large-scale glazed sliding / lifting-sliding elements, which in professional circles are also referred to as "moving walls", are becoming increasingly popular. Due to their size and the insulation purposes usually provided triple glazing such sliding elements are relatively heavy. Their weight can be up to 400 kg. Such heavy sliding elements can pose an increased risk of accidents due to their inertia, for example, when a person collides with a moving wing or is trapped between the door and door frame or window and window frame. Despite this danger, hand-operated sliding / lifting / sliding elements have so far not been provided with any anti-pinch devices.

It is therefore an object of the invention to make a sliding element of the type mentioned safer and in particular to avoid the risk of trapping persons and objects.

The object is solved by the features of claim 1 and in particular by the fact that a safety device with a provided in the region of a closing edge of the wing contact element and with a brake device operatively connected to the contact element is provided, by which, when the contact element is pressurized against the closing direction of the vane, a movement of the vane can be braked, in particular up to its stoppage.

As soon as the wing which moves in the closing direction encounters an obstacle in the area of the closing edge, it exerts a pressure on the contact element, whereby the wing is braked and brought to a standstill. A person who is in the passage area between door leaf and door frame or window sash and window frame during the closing process or reaching into this area is thus protected from crushing injuries. In addition, damage to the wing itself and objects in the passage area are prevented.

According to an advantageous embodiment of the invention, the braking device comprises at least one brake element, which is adjustable between a braking position in which it presses against a fixed friction surface, and a release position in which it is spaced from the friction surface. By means of such a braking element cooperating with a friction surface, a reliable braking of the wing is achieved, without it being necessary for this to intervene in the carriage or roller mechanism of the sliding element and to cause undesired wear there.

According to a further preferred embodiment of the invention, the brake element in the release position on a bias in the direction of the braking position. In this way, necessary for braking the wing pressure force between the brake element and the friction surface of the necessary to trigger the brake device contact force be decoupled. Thus, even with a slight pressurization of the contact element against the closing direction of the wing, the brake element with a predetermined high force press against the friction surface. In this way, no power-operated additional mechanisms for operating the brake device are needed.

Preferably, means are provided for biasing the brake element by pushing back the wing against the closing direction or when unlocking or locking the wing, in particular by a lifting or lowering operation of the wing. This has the advantage, in particular with lifting / sliding elements, that the potential energy of the raised door or window wing can be used for pretensioning the brake element and that specially operated cocking slides or clamping levers are superfluous. In this case, the entire braking device can preferably be realized on a purely mechanical basis, without the need for expensive and expensive auxiliary systems based on hydraulics, pneumatics or electromechanics.

According to a further advantageous embodiment of the invention, a latch mechanism is provided, which is able to hold the brake element against the bias in the release position. Triggering of the braking device is thus possible by simply disengaging the latch mechanism, wherein the contact element may be directly or indirectly engaged with the latch mechanism.

Preferably, the latch mechanism comprises a pivoting lever with a pawl which can be latched with a supporting notch associated with the braking element. The brake element is securely held by the latched in the support groove pawl of such a pivot lever under bias, wherein at a unlatching of the pawl Preload ensures that the brake element presses directly against the friction surface and the moving wing is brought to a standstill quickly.

The contact element may be formed in particular as a mechanically actuated pressure bar. Such a pressure bar is easy to manufacture and ensures a high degree of reliability. The pressure bar preferably extends parallel to the closing edge of the wing and protrudes beyond the closing edge in the closing direction. If, during a closing process, an obstacle in the form of a person or an object is located in the opening area of the sliding element, the pressure bar first encounters the corresponding obstacle. The braking device is thus activated before the main closing edge of the wing hits the obstacle.

Preferably, the pressure bar is biased in the closing direction to ensure a permanent activation of the braking device.

According to a further preferred embodiment of the invention, the pressure bar extends substantially over the entire height of the wing. In this way, the entire area of the closing edge is protected, i. it does not matter to the safety device at which height there is an obstacle hit by a moving wing.

The braking device can furthermore be designed to decelerate a movement of the wing upon actuation of a gripping element of the fitting arrangement. This may be advantageous to allow emergency braking of the wing by a user when detected danger.

According to a further advantageous embodiment of the invention, the braking device comprises an attachable to a frame of the sliding element brake rail. The brake rail provides the friction surface for the brake element and may be configured in nature such that an optimal immediate braking effect is achieved. The braking device may be provided, for example, at an upper edge region of the sliding element, wherein the brake rail is secured to an upper cross member of the frame.

The brake device may comprise a brake caliper encompassing the brake rail with two opposing brake shoes. The brake shoes can be adapted in terms of material and shape to the friction surface of the brake rail to ensure an effective braking effect. By embracing principle unwanted unilateral pressure loads on the wing and its storage are avoided. The brake rail can in particular be cantilevered. This ensures good support of the brake shoes during braking. Preferably, the brake shoes press in the horizontal direction against the brake rail to avoid unwanted loading of the guide rail and the rollers of the wing in addition to the weight of the wing.

The brake caliper can be designed in various ways and include, for example, a fixed brake lever and a movable brake lever. In the movable brake lever may be provided a recess for engagement of a biasing bolt, wherein the recess may be adapted in its contour to the respective force and direction requirements. Preferably, a cover for provided the braking device, since it is advantageous to attach the braking device to the outside of the sliding element.

According to a further advantageous embodiment of the invention, a transmission element is further provided, which is displaceable by a force acting against the closing direction of the blade on the contact element force substantially perpendicular to the closing direction. The transmission element can be designed, for example, rod-shaped or rail-shaped. It serves for the forwarding of the pressure force acting on the contact element to another area of the wing in order for example to create a connection between a contact element arranged in the middle of the closing edge and a braking device arranged on the upper edge area of the wing.

For this purpose, wedge elements with inclined surfaces may be provided on the rear side of the contact element, wherein the inclined surfaces cooperate with oppositely oriented inclined surfaces provided on the transmission element wedge elements to implement a movement of the contact element perpendicular to the closing edge in a movement of the transmission element parallel to the closing edge. The wedge elements enable a simple and reliable power deflection of 90 °.

Preferably, a corner deflection is further provided to implement a movement of the transmission element parallel to the closing edge in a movement of an actuating element of the braking device perpendicular to the closing edge. In the case of a horizontally displaceable vane, for example, the force acting on the contact element against the closing direction can first be converted into an upwardly directed movement of the transmission element, which subsequently acts on the contact element upper end of the fitting assembly is converted by means of the corner deflection in a horizontal movement of the actuating element.

This horizontal movement of the actuating element can be used to activate the braking device at the upper edge region of the wing, so for example for notching a pawl by means of a pivot lever. Thus, a total of a purely mechanical way, a transmission of the pressurization of the contact element is made possible to a trigger mechanism of the braking device. The Eckumlenkung can be arranged in particular between two cuff rail elements and thus integrated to save space in the fitting arrangement. A sliding by a actuation of a handle member of the fitting assembly gear bar can be operatively connected to the corner deflection, to bring about a bias by raising or lowering the wing.

Possible developments of the invention are specified in the dependent claims, the drawings and the description.

In Fig. 1 a sliding door according to the invention is shown, which comprises an outer frame 10, a fixed door leaf 12 and a horizontally displaceable door leaf 14. The sliding door 14 has a rotatable actuating handle 16 and is mounted in the outer frame 10 by means not shown sliding or roller guides. The sliding door is formed as a hand-operated lift-slide door, wherein the sliding door 14 can be raised by a rotation of the operating handle 16 and moved in the raised state relative to the outer frame 10. The fixed door leaf 12 and the sliding door leaf 14 each have a frame made of wood, metal or plastic and arranged in the frame safety glass on. When the sliding door 14 in the in Fig. 1 Located on the left-most closed position, the interior of the outer frame 10 is covered by the two door leaves 12, 14. If the sliding door 14 against the closing direction S in the in Fig. 1 moved to the right opening position, it releases a located within the outer frame 10 passage area 18.

The sliding door is equipped with a safety device to prevent accidents due to pinching. The safety device comprises a contact element 20 which is provided in the region of a closing edge 22 on the frame of the displaceable door leaf 14, and a braking device 24 which is provided in the upper edge region of the displaceable door leaf 14. To make the sliding door visually appealing, the braking device 24 is covered with a cover 26. The contact element 20 basically interacts with the braking device 24 in such a way that, when the contact element 20 is pressurized against the closing direction S of the displaceable door leaf 14, a movement of the displaceable door leaf 14 is decelerated.

The following are with reference to the Fig. 2 . 3 and 4 Structure and function of the contact element 20 and the brake device 24 explained in more detail. On the outer frame 10 of the sliding door, a brake rail 27 is mounted in flying storage. For this purpose, a mounting plate 70 is attached to the outer frame 10 with projecting retaining bolts 28. The retaining bolts 28 are slidably passed through the brake rail 27. At the side facing away from the outer frame 10 of the brake rail 27, the retaining bolts 28 are fixedly connected to a retaining plate 29. Between the mounting plate 70 and the brake rail 27, springs 71 are provided, which are guided on the retaining pin 28. The springs 71 urge the brake rail 27 in the absence of external forces against the retaining plate 29th

The brake rail 27 is associated with a brake caliper 30 which is fixed to the sliding door 14. The brake rail 27 is encompassed by the brake caliper 30 such that it is located between two opposing brake shoes 32, which are provided at one end 31 of the brake caliper 30. The brake caliper 30 comprises a fixed brake lever 34 and a movable brake lever 36, wherein the movable brake lever 36 is mounted by means of a connecting plate 38 and a pivot pin 39 on the fixed brake lever 34, that it relative to this between a in Fig. 2 shown release position and a in Fig. 3 shown brake position is pivotable. A bolt 40 attached to the fixed brake lever 34 fixed and passed through the movable brake lever 36 carries a brake spring 42 which presses against the movable brake lever 36 and biases it in the direction of the release position.

At the brake shoe 32 opposite end 33 of the brake caliper 30, a latch mechanism 44 is provided to hold the brake caliper 30 against the bias of the brake spring 42 in the release position. The latch mechanism 44 includes a trip lever 46 to which a pawl member 48 is attached. Alternatively, a pawl could also be formed directly on the trigger lever 46. The release lever 46 is mounted at the end 33 of the brake caliper 30 by means of a pivot pin 47 pivotally mounted on the fixed brake lever 34. The pawl member 48 is latched to a support groove 50 formed on the movable brake lever 36. In order to ensure a correct pivoting of the release lever 46 despite the provided locking, the pawl member 48 and the support groove 50 each have a curved shape which corresponds to a drawn around the pivot pin 47 circle. When engaged pawl member 48, the two brake levers 34, 36 at the end 33 of the brake calliper 30 against the biasing force of the brake spring 42 held together. Upon release of the locking, the two brake levers 34, 36 are pressed apart by the biasing force of the brake spring 42 in the braking position.

At the end 33 of the brake caliper 30, a tensioning lever 52 is further provided which is pivotally mounted about a pivot pin 53 to the fixed brake lever 34 and engages with a clamping bolt 54 in a recess 56 of the movable brake lever 36. As in Fig. 2 and 3 can be seen, the clamping bolt 54 slides during pivoting of the clamping lever 52 along the fixed brake lever 34th facing edge of the recess 56, ie the recess 56 and the clamping bolt 54 form a slotted guide. Upon pivoting of the clamping lever 52 in a biasing direction V thus a movement of the movable brake lever 36 is brought into the release position.

In order to implement a pressurization of the contact element 20 against the closing direction S in an actuation of the release lever 46, a mechanism is provided, which hereinafter with particular reference to Fig. 4 is explained in more detail. The contact element 20 is designed as a pressure bar which extends parallel to the closing edge 22 of the movable door leaf 14 substantially over the entire height of the movable door leaf 14 and projects beyond the closing edge 22 in the closing direction S.

Depending on the application, the pressure bar 20 can be subdivided into a plurality of individual elements or else formed in one piece. In order to allow a correct, sealing engagement of the sliding door leaf 14 with the outer frame 10 despite the protruding of the pressure bar 20, a matching recess for receiving the pressure bar 20 can be provided with the door closed 14 at the appropriate place in the outer frame 10 or in its fitting be. The pressure bar 20 is integrated into a fitting arrangement assigned to the displaceable door leaf 14 such that it can be displaced in the horizontal direction according to an arrow 57 relative to the door leaf 14. At the sliding door 14 facing side of the pressure bar 20, two wedge elements 58 are provided with inclined surfaces 59. Further, wedge elements 60 are provided with counter-aligned inclined surfaces 61 on a release latch 62 to form a run-on slope, wherein the wedge elements 58 of the pressure bar 20 associated inclined surfaces 59 in sliding engagement with the wedge elements 60 of the release bolt 62 associated inclined surfaces 61 are. The release latch 62 is integrated into a fitting groove of the sliding door 14 such that it is displaceable in the vertical direction according to an arrow 63 relative to the door leaf 14. The release latch 62 is further connected to a corner drive 64, which converts the movement of the release latch 62 in the direction of the arrow 63 in a movement of a transmission lever 66 in the horizontal direction according to an arrow 65. The transmission lever 66 engages with a release pin 67 ( Fig. 2 and 3 ) in a formed in the release lever 46 slot 69 a.

In order to ensure a bias of the pressure bar 20 against the arrow 57, an in Fig. 4 schematically illustrated spring element 74 is provided, which is on the one hand with a fixed component 75 of the sliding door 14 and on the other hand with the release latch 62 in conjunction. The spring element 74 presses the release latch 62 in the absence of pressurization of the pressure bar 20 against the arrow 63 and thus the pressure bar 20 against the arrow 57 in a starting position ready to trigger. The pressure required for triggering pressure is adjustable depending on the requirements of the biasing force of the spring element 74.

When the pawl member 48 as in Fig. 2 shown engaged in the support groove 50, the two brake levers 34, 36 are held together at the end 33 of the brake caliper 30 and thus kept apart at the opposite end 31. The brake caliper 30 is in the release position, in which the two brake shoes 32 are spaced from the brake rail 27. A displacement of the door leaf 14 relative to the outer frame 10 is thus possible without hindrance.

When taking place against the closing direction S force on the pressure bar 20, this is displaced in the direction of the arrow 57 relative to the door leaf 14. Via the wedge elements 58, 60 with the inclined surfaces 59, 61, the horizontal movement of the pressure bar 20 according to the arrow 57 is converted into a movement of the release latch 62 in the vertical direction according to the arrow 63. This movement of the release bolt 62, in turn, causes a displacement of the transmission lever 66 in the direction of the arrow 65 via the corner drive 64. The transmission lever 66 causes the release lever 46 to pivot about the pivot pin 47 via the release bolt 67 sliding in the slot 69, so that the pawl element 48 out of engagement with the support groove 50 device.

The guided on the bolt 40 brake spring 42 now urges the movable brake lever 36 and the fixed brake lever 34 apart, thus causing a pivoting of the movable brake lever 36 about the pivot pin 39 in the braking position. The brake shoes 32 move towards each other and the brake shoe 32 of the movable brake lever 36 finally abuts against the brake rail 27. Due to the flying support of the brake rail 27 is this by the movable brake lever 36 against the biasing force of the springs 71 on the retaining bolt 28 slidably in the direction of Mounting plate 70 moved.

Once the brake rail 27 abuts against the brake shoe 32 of the fixed brake lever 34, their further displacement is prevented. The brake rail 27 is clamped in the sequence under the force of the brake spring 42 evenly between the brake shoes 32. Since the brake rail 27 is fixed to the fixedly anchored outer frame 10 of the sliding door, while the brake calliper 30 is mounted with the brake shoes 32 on the sliding door 14, the frictional force between the brake rail 27 and brake shoes 32 causes a braking of the door leaf 14. With sufficient mediated by the brake spring 42 braking force of the door 14 thus comes to a standstill.

Such a braked door 14 can be released again by once lowered by the operating handle 16 and raised again. For example, the biasing lever 52 can be pivoted in a lowering of the door leaf 14 in the biasing direction V. The sliding on the edge of the recess 56 along clamping bolt 54 then presses the movable brake lever 36 against the biasing force of the spring 42 in the release position. Once the movable brake lever 36 is in the release position, the bias of the spring element 74 causes a movement of the release latch 62 against the direction of the arrow 63 and thus on the Eckumlenkung 64 a movement of the transmission lever 66 against the direction of arrow 65. The pressure bar 20 is So pushed in the closing direction S to the outside and the pawl member 48 engages again in the support groove 50 a. Now the door 14 can be moved freely again.

The braking device 24 is designed purely mechanically and can be integrated in an advantageous manner in a fitting arrangement for a lift-slide door. In particular, the braking device can be arranged between two cuff rail elements of a conventional fitting arrangement without requiring a fundamental redesign of the fitting arrangement.
