Description

Sliding element

Technical Field

The invention relates to a sliding element, in particular a sliding door or a lifting sliding door, having a housing, a wing which is movable relative to the housing, and a locking device for selectively locking the wing to the housing.

Background

Such sliding elements are increasingly popular, for example in the form of large-area floor doors or french windows, but are also used in the form of sliding walls for temporarily separating specific areas in a room. The direction of movement of the wings extends horizontally in the mounted slide element. Metal fittings in the form of a trolley structure, the rollers of which roll on underlying rails or overhead rails, can be provided on the wings. The outer frame may be any fixed bearing for supporting the movable wing. That is, the outer frame need not be frame-like in this sense, so that it has a closed shape.

Of particular importance to doors and landing doors: the closed and locked wings cannot be pushed or pulled by increasing the force consumption. Thus, a conventional sliding element may be provided with a catch. In such a catch, a hook is provided which can be pivoted out of the front closing edge of the wing, which hook can be twisted by means of a handle, such as a turning knob, so that the hook can be selectively engaged or disengaged in the hook receiving portion of the outer frame.

The catch has a relatively complex structure. Further, the operation of rotating the knob or rotating the knob during each opening and closing process is troublesome for the user.

Disclosure of Invention

The aim of the invention is to simplify the locking and unlocking of a sliding element.

The object of the invention is achieved by a sliding element having the features of the invention.

In the sliding element according to the invention, the locking device comprises a locking pin which is mounted on the casing or on the wing such that it can be moved between a retracted release position and an extended locking position and is designed for a locking engagement with a retaining edge provided on the other element of the casing and of the wing, wherein the locking pin is prestressed in the extended locking position by means of a spring device.

In this sense, the arresting engagement between the locking pin and the retaining edge is to be understood as: the locking pin is automatically inserted when the wing is closed and then prevents the return movement of the wing. That is, when the wing is in the closed position and the latch is in the extended, locked position, movement of the wing is inhibited. Then, in order to be able to push and pull the wings, the locking pin must first be moved into the retracted release position. That is, the movable latch is able to automatically lock the wings during closing. The user simply pushes the wing into the closed position to allow the locking pin to be inserted and thereby establish the locked condition. No operating handle or the like is required. Handles may be provided on the wings to facilitate sliding. Since such a handle does not need to be mechanically coupled to the locking device, the handle can be arranged at any position on the wing. Unlike pivotable hooks, movable latches enable simpler, cheaper and more space-saving designs.

The locking pin may be mounted directly or indirectly to the frame or to the wing. For example, the locking pin can be mounted on a metal piece designed for fastening on the outer frame or on the wing. The retaining edge can likewise be formed on a metal part designed for fastening on the wing or on the outer frame. However, the retaining edge is preferably formed directly on the frame profile of the wing or of the outer frame.

Preferably, the locking pin is movable transversely to the closing direction of the wing. This ensures a reliable locking effect against the closing direction of the wings.

More preferably, the locking pin has an impact ramp for the closing edge of the wing or a component loaded by the closing edge, and is embodied in particular as a ramp locking pin or as a toggle locking pin. When the wing leading edge or the loaded component strikes the impact ramp, the locking pin automatically moves into the retracted release position, so that the retaining edge can pass over the locking pin. Next, the locking pin is pushed back into the extended position again by the force of the spring device, where the locking pin engages behind the retaining edge in a form-fitting manner.

According to one embodiment of the invention, the retaining edge extends along the closing edge of the wing over an engagement region which widens against a corresponding widening of the locking pin. That is, with respect to the closing edge of the wing, the retaining edge is advantageously longer than the locking pin. Such locking devices are also suitable for lifting sliding doors, the wing parts of which perform a combination of a sliding movement and a lowering movement in the final phase of the closing process.

According to a particular embodiment, the retaining edge extends at least substantially along the entire closing edge of the wing. Accordingly, it is not important in which position the locking pin is. Thus, wings with such retaining edges can be combined with different frames involving locking pin structures.

The locking pin receptacle for the locking pin can be provided on the wing or on the outer frame, wherein the retaining edge is formed by an edge of the locking pin receptacle. A particularly reliable locking can thereby be achieved.

The locking pin receiver can be formed by a recess or depression of the wing or of the outer frame, in particular of the outer frame profile or of the wing profile. Preferably, the retaining edge is formed integrally with the outer frame profile or the wing profile. In the simplest case, an elongated groove or recess can be provided as a recess or recess of the wing or of the outer frame.

According to a further embodiment of the invention, the casing comprises a closing edge receptacle for the closing edge of the wing, wherein the locking pin is supported on the casing and projects into the closing edge receptacle when the locking pin is in the locking position. In this embodiment, the locking pin passes directly through the front of the wing, so that a particularly reliable locking effect is achieved.

The wing may have a closing edge comprising a front contact face and a wing projection which projects from the front contact face and is designed for engagement in a closing edge receptacle. This embodiment makes it possible to realize a particularly hermetically closed sliding element. In order to increase the sealing effect, at least one sealing element can be arranged on the contact surface. The contact surface does not have to bear directly against the outer frame when the wing is closed, but can, for example, merely press one or more sealing elements against the outer frame. In this embodiment, the part of the closing edge that is intended to carry the sealing element can likewise be understood as the contact surface.

The sliding element according to the invention can comprise a damping device which is arranged on the outer frame and is designed to exert a resistance force against the movement of the impacting wing when the sliding element is closed. This makes it possible to avoid an undesirably strong impact of the wings on the outer frame during the closing process.

The damping device may comprise a contact element having an impact surface for the closing edge of the wing, which contact element is prestressed against the closing direction of the wing by means of a compression spring. Such damping devices are used as a force accumulator. The stored energy can be used to support the displacement movement when the wing is opened, in order to reduce the effort required for opening the wing and to make the operation of the sliding element easier.

The damping means can be arranged sunk in the closing edge reception of the casing, so that the damping means are not or hardly visible from the outside. This design ensures a particularly pleasing appearance of the albizzy element.

The locking pin can be moved into the retracted release position by the actuating device against the biasing force of the spring device. In particular, the actuating device can comprise a preferably electric drive for the locking pin and an operating element for activating the drive. The operating element can be constructed relatively small and unobtrusive compared to a twist grip or a twist knob. In the simplest case, the operating element can be designed as a simple start button or release button. If the locking pin is arranged on the outer frame together with the drive and the actuating element, the wing can be held completely freely by the respective actuating and actuating element as required.

Preferably, the sliding element according to the invention is configured as a lifting sliding door. The wings of such a sliding door lie on the floor-side guide rails in the closed state, so that a high sealing and particularly reliable holding is achieved. Unlike the hook lock, a locking device with a movable locking pin is also suitable for lifting sliding doors.

Further embodiments of the invention are given in the description and in the drawings.

Detailed Description

The lifting sliding door 11 shown in fig. 1 includes an outer frame 13, a fixed wing 15a, and a sliding wing 15 b. The outer frame 13 is fixedly connected to the building wall 17. During the fixed wing 15a being fixedly connected with the outer frame 13, the sliding wing 15b is slidable with respect to the outer frame 13 along and against the horizontal closing direction S. For this purpose, a mechanism may be provided which comprises a plurality of travelling carriages which can travel along the guide rail.

The sliding wing 15b includes a wing frame 19 and a vitrification element 21 held by the wing frame 19. The wing frame 19 consists of hollow profile elements 20, 20', which are preferably made of plastic or aluminum. The fixed wing 15a likewise comprises a vitrification element 21, which is held by the hollow profile element 20' and by the outer frame 13.

The hollow profile element 20 of the sliding wing 15b, which is located on the left in the drawing, contacts the outer frame 13 in the closed position of the sliding wing 15b shown in fig. 1 and thus forms the closing edge 25 of the sliding wing 15 b. The hollow profile element 20 forming the closing edge 25 also has a front contact surface 27 from which a central wing projection 29 projects. A sealing element 30 made of an elastic material is mounted on the outer edge region of the contact surface 27.

As shown in particular in fig. 2, a recess 33 which is triangular in cross section is provided on one side of the wing projection 29 and preferably extends over the entire height of the sliding wing 15 b. The recess 33 serves as a detent receiver for a detent 35 which has an impact ramp 45 and is mounted in the outer frame 13 so as to be movable transversely to the locking direction S.

The locking pin 35 is designed here as a simple beveled locking pin and is accommodated in a locking pin housing 37 inserted into the outer frame 13. The locking pin 35 is pretensioned in the extended locking position shown in fig. 2 by a spring device (e.g. a compression spring) which is not shown. In this position, the locking pin 35 projects into a recess 39 of the outer frame 13.

A damping device 40 is provided in the recess 39 for braking the sliding wing 15b shortly before the closed position is reached. The damping device 40 comprises a contact element 41, for example in the form of a plate, a disk or a strip, and a spring arrangement 43, which in the end position shown in fig. 2 pretensions the contact element 41 against the latching direction S. In this end position, the contact element 41 is flush with the outer frame 13 as shown. The front side of the contact element 41 forms an impact surface 42 for the wing projection 29.

When the sliding wing 15b is closed from the position shown in fig. 2, the wing projection 29 strikes the contact element 41 and is thereby braked under tension of the spring arrangement 43. During the arrival of the wing projection 29 in the recess 39, the back side 44 of the contact element 41 strikes the impact ramp 45 of the detent 35 and presses the detent 35 against the force of the spring device from the recess 39. Next, the locking pin 35 is inserted or snapped into the slot 33 of the wing tab 29, as shown in fig. 3. The positioning of the slot 33 is chosen such that the insertion of the detent 35 takes place at least substantially simultaneously with the collision of the sealing element 30 against the outer frame 13. Then, the sliding wing 15b is in the closed position and locked with respect to the outer frame 13, since the locking pin 35 engages the edge of the rear engagement groove 33 constituting the retaining edge 46 (fig. 2). The arrangement of the locking pin 35 and the recess 33 thus forms a locking device 47 of the lifting sliding door 11. The cross-sectional shape of the detent 35 is adapted to the cross-sectional shape of the recess 33 such that the detent 35 is received flush in the recess 33.

To unlock and open the sliding wing 15b, the locking pin 35 can be moved into the retracted release position against the biasing force of the spring device by means of an electric drive (e.g., an electromagnetic actuator), which is not shown. The electric drive can be activated by means of an activation button 50 provided on the casing 13. Once the locking pin 35 is retracted, the locking of the sliding wing 15b is removed and the sliding wing 15b can be pushed and pulled. The opening movement of the sliding wing 15b is supported by the spring structure 43 of the damping device 40, so that the sliding wing 15b can be opened with relatively little force consumption. In order to open the lifting sliding door 11 both from the outside and from the inside, a further activation button may be provided, which is not shown in the figure.

Since the recess 33 is significantly longer than the engagement area of the detent 35, the sliding wing 15b can easily perform a movement with a vertical component during the insertion of the detent 35 into the recess 33, that is, the sliding wing 15b can be lowered when closed.

Fig. 4 and 5 show an alternative embodiment of a lifting sliding door 11' according to the invention, which has a similar construction to the lifting sliding door 11 described above. However, the wing frame 19' is not formed here from a hollow profile, but is constructed solid. Furthermore, the contact surface 27' of the wing projection 29' is of relatively narrow design and is covered over the entire surface by the sealing element 30 '. Another difference compared to the embodiments shown in fig. 1-3 is that: the locking pin 35' is not mounted directly on the casing 13 but in a lock case 55 constructed as a metal piece, in which an electric drive is also placed and on which the activation button 50 is mounted. As shown in fig. 4, the locking pin 35' is designed as a noise-suppressing crank locking pin and accordingly comprises a crank lever 65.
