EP3109385B1 - Closure device for a door with a single or multi-part door leaf - Google Patents

Description

The invention relates to a locking device in runner profiles for a door with a one-part or multi-part door leaf that can be moved in lateral runner profiles by rollers.

In the DE 20 2008 002 932 U1 is a closure element for closing a wall opening with at least one safety device that locks the closure element in the closed position, which consists essentially of a safety bolt and a receptacle that accommodates the safety bolt and a blocking slide that at least partially penetrates the receptacle, which is designed to be horizontally displaceable and spring-loaded, wherein in the closed position of the blocking slide interacts with the safety bolt in such a way that the closed position can only be released by a mechanical unlocking device fastened in or on the closure element.

The DE 101 24 359 C1 discloses a lifting folding door for garages or the like with a door leaf which consists of two hingedly connected door leaf halves of approximately the same size, of which the upper door leaf half is pivoted at its upper edge above the door lintel on a lintel frame and of which the lower door leaf half is mounted at its lower edge Edge with laterally projecting rollers in rails from a closed position, in which the two halves of the door leaf lie in one plane, into an open position in which the two halves of the door leaf protrude approximately horizontally, is vertically movable. A lock rod of a conventional gate lock is slidably mounted in order to initially withdraw the introductory opening movement from its locking position by locking members actuated by it, eg via Bowden cables or the like, in order to then raise the gate.

A multiple locking system for a door, which is operated by a central lock, gives the U.S. 1,693,481 again.

The DE 10 2008 013 685 A1 discloses a safety device and a safety method for a door, in which the door leaf can be locked in a closed position by means of the locking device and the locking device can be moved in a locking position by means of the door leaf relative to the switching device in such a way that a switching pulse is generated when the door leaf moves. Just by moving the door leaf, for example, a switching device will trigger an opening process. The safety device only works when a switching pulse is generated, which happens when the locking device or the gate is locked.

through the EP 1 630 326 A1 discloses a device for locking a closure structure of a gate, in which a movable member is movable relative to a frame between an open and a closed position. A locking element is movably mounted on the component or the frame, and on the frame or the component there is a latching element which is fixed at least in a locking position and is used for locking. This device is intended to increase burglary security.

The object of the invention is to provide a locking device for a one-part or multi-part door leaf that can be moved in the side runner profiles, which can be integrated into the side runner profiles in a tamper-proof manner and also does not require any additional space. Such a closure device should not only be usable in the closed position of the door leaf, but also in open positions.

The object of the invention is achieved by the features of claim 1. The subclaims relate to a further embodiment of the idea according to the invention.

The following description refers to a door formed from a plurality of door elements connected to one another in an articulated manner, as can be found, for example, in sectional doors. Nevertheless, the inventive locking device can also be used with one-piece door leaves.

In a first preferred embodiment, the closure device according to the invention is divided into a stationary part and a part that can be moved. The stationary part is arranged within at least one runner profile for the door leaf, with the door leaf being guided in runner profiles on both sides. The rollers, which are connected to the individual door elements that are connected to one another in an articulated manner, dip into the running profiles. The flat locking plate is designed in such a way that this is provided at its ends with bevels pointing in the longitudinal direction of the running profile. Such a locking plate includes a movably mounted holding piece that contains a latch receptacle. The rotatable holding piece is mounted within the locking plate and is thus loaded by at least one spring element. In its rest position, the holding piece protrudes partially out of the locking plate in such a way that the bolt receptacle is suitable for receiving a bolt, which is part of the movable part, in a locking position. The locking position does not only have to include the closed position of the door leaf, but can be implemented in any desired position of the door leaf, as the following description will make clear.

A locking piece, preferably attached to the movable gate element close to the ground, interacts with the stationary arrangement of the locking plate. The latch piece is a component that includes a protruding rigid latch. When passing the locking plate, this bolt is automatically contacted by the holding piece protruding into the movement path of the bolt with the bolt receptacle. The bolt gets into the bolt receptacle of the locking plate. This automatically locks the door securely, for example in its closed position. It should be noted that the combination and the interaction between the locking piece with the rigid locking bar and the stationary locking plate can be arranged in any position via the holding piece, also in multiple versions within the running profiles. In addition to a so-called ventilation position, this can also involve a partial opening position or different opening positions of the door leaf.

Since the locking plate is arranged within at least one, preferably both, runner profiles, it is also possible to use a wide variety of profile types. In a preferred embodiment, a so-called J profile is suitable. However, C-profiles can also be used.

The locking piece is preferably mounted on a base plate and thus at the same time assumes a partial bearing and connection to the door element in question for the rollers. In this case, a roller is arranged at each end of the stretched version of the locking piece. The rollers each have a roller axle that is mounted in a roller bearing or in a fitting that is connected to the door element. It is possible for the fitting to have two receptacles for roller axles arranged at a distance from one another at the same time. However, it is also possible that, for example, in one embodiment of two adjacent door elements Fitting element is assigned, so that the locking piece can be divided over the roller axes to two gate elements. The roller axles are freely movable in the horizontal direction in the fitting, which is achieved through coordinated play. In this way, tolerances between the door leaf and the runner profiles can be compensated for without any problems when the door is opened or closed.

In order to get the gate out of the locking position, this can be accomplished by a wide variety of manipulations in a purely mechanical or also in an electromechanical form. In a purely mechanical design, for example, a lock or a handle can be used in the closed position of the door leaf. When the lock is actuated, the rotary movement is transmitted to the locking device via a transmission element. For example, a release element in the form of a Bowden cable can be used to exert a force on a release element associated with the locking piece, which force ensures that the retaining piece is pushed back into the locking plate by the release element. The result of this is that the bolt previously engaging within the retaining piece is released. The position of the gate can then be changed.

In the case of the lock unit, to release the locking position, a design can preferably also be selected which can carry out a holding piece actuation to be carried out in the same way inside and outside the building.

Instead of the triggering element, a lever mechanism can also be used to apply pressure to the holding piece in the locking plate.

In a further preferred embodiment, it is also possible to use electromechanical mechanisms which, for example by means of a start command for the drive motor of the gate, cause the locking position to be released.

Further advantages, features and application possibilities of the present invention result from the following description in connection with the exemplary embodiments illustrated in the drawings, where not all figures show bevels of the locking plate according to the invention.

In a first preferred embodiment, the closure device 1 consists essentially of a mobile part, which can be assigned to a mobile door element 3 , and a stationary part, which is arranged stationary within a running profile 2 . The 1 shows the gate element 3, which belongs to a gate, which can be moved in the lateral running profiles 2 by means of rollers 16, 17. The running profile 2 is attached to a stationary fastening element 4, for example in the form of a frame or a frame. The representation of 1 shows the door element 3 from the inside. A lock unit 6 has been shown in which a profile cylinder 8 and a handle 34 are shown. Both the profile cylinder 8 and the handle 34 make it possible to bring the locking device 1 out of its locking position. This is possible, for example, by a triggering element 7 which acts on a movable part of the closure device 1 . Furthermore, a roller bearing has been shown on the door element 3 in a fitting 5 in which a roller axis 10 is mounted.

The 2 shows the same door element 3 but from the outside, in which a lock unit 13 is shown from the outside. The profile cylinder 8 has also been reproduced within the lock unit 13 .

through the 3 the two-part structure of the closure device 1 is illustrated. In a base plate 14, the triggering element 7 is passed through a transfer piece 12 and stored. At the same time, the roller axles 10 and 11 are mounted in the base plate 14, with this part of the closure device 1 being able to be moved by the connected gate element 3. A stationary part, in the form of a locking plate 18, is operatively connected to the part that can be moved. With the fastening element 4, the running profile 2 is connected in this embodiment, which is preferably designed as a J-profile. At the left end of the release element 7, the inner part of the lock unit 6 has been shown. The entire closure device 1 is shown in the perspective view 4 shown in connection with lock units 6 and 13.

The stationary part of the locking device 1 consists essentially of the locking plate 18 in which a retaining piece 21 is arranged so that it can move within a recess 31 is. The holding piece 21 has a bolt receptacle 22 for a bolt 15 which is assigned to the stationary part of the closure device 1 . The holding piece 21 is an axis 33, after 9 , Within the recess 31 movably arranged. The holding piece 21 is loaded by spring elements 32 in such a way that the holding piece 21 protrudes from the locking plate 18 in its normal position so that it can interact with the second part of the locking device 1, namely the bolt 15, in the locking position. The locking plate 18 has bevels 19 at its upper and lower ends, and fastening bores 30 are also included in order to be able to set an exact alignment within the running profile 2 for the desired locking position. How the holding piece 21 protrudes in its basic position from the locking plate 18, shows the 10 .

In the locking position, the non-movable bolt 15 interacts with the locking plate 18 . A position in which the bolt 15 is outside in the locking position, the 4 be removed.

The entire closure device 1 with the mobile part and the stationary part is the figure 5 refer to. The locking plate 18 with the holding piece 21 pivoted out in the locking position is visible on the right-hand side. The bolt 15 , which is part of a bolt piece 23 , engages in the bolt receptacle 22 . This makes it clear that the bolt 15 has no moving part in its position as such and is therefore rigid. The locking piece 23 is fastened to the locking bar 15 on the base plate 14 . Within the locking piece 23, the roller axes 10, 11 are mounted. In this representation, the roller bearing 5 is shown in connection with a fitting 5, in which the roller axis 10 penetrates within the fitting 5 with play. This makes it possible that when the door element 3 moves, the part of the closure device 1 that can be moved is inevitably carried along via the roller axles 10 and 11 . The rollers 16, 17 are positively guided within the running profile 2.

The structure of the mobile part of the closure device 1 can in particular Figures 6 and 7 , in the respective individual representations. It is clear here that the locking piece 23 is molded onto the locking bar 15 . This means that the latch 15 as such cannot perform any movement, in particular no horizontal movement. In order to bring the holding piece 21 out of a locking position, it is necessary for the holding piece 21 to recede from a surface 20 of the locking plate 18 or be at the same level as the surface 20 located in order to achieve a solution of the locking position when the locking piece 23 moves past the holding piece 21 .

The position of the holding piece 21 can only be changed by the release element 7 in a purely mechanically operating embodiment. The release element 7 acts on a release element 26 . Such a release element 26 is the 8 refer to. Via a bore 27, which is arranged at one end of the release element 26, a one-armed lever is created, which can be pivoted about a pivot point of the bore 27 and has a projection 28 at the other end. This projection 28 penetrates in the embodiment of Figures 6 and 7 the locking piece 23 and is thus mounted in the locking piece 23 via the bore 27. If a pressure force is now exerted by the release element 7 on a pressure point 29 of the release element 26, the release element 26 pivots in the direction of the locking plate 18 and thus brings the projection 28 to rest on the surface of the holding piece 21 and presses against the spring force of the spring elements 32 Holding piece 21 into the locking plate 18 inside. Conversely, it is conceivable for the disengaging element 26 to be subjected to a tensile force in order to release the triggering element 7 .

The 11 shows the arrangement of the locking plate 18 within the running profile 2 again. The running profile 2 has been designed as a J-profile. When training as a C-profile, it is necessary to provide the rollers 16, 17, which are otherwise used in this form with a crowned running surface, smooth or with a shoulder.

The Figures 12 to 15 show a modified embodiment of the locking device 1. An internal lock unit 35 has been shown with which the handle 34 is connected. When the handle 34 is actuated, a transmission member 36 acts on a transmission lever 37 in such a way that when pressure is applied, the release element 26 is pressed with its projection 28 against the holding piece 21 . Here, the design of the release element 26 has been used in a modified version, as the 15 can be seen, furthermore, the locking piece 23 has not been shown, but what the 14 can be seen.

As the described preferred embodiments make clear, the closure device 1 can be arranged, for example, in the closed position of the door leaf. However, it is also possible to additionally use such a closure device 1 in the open position. In order to be able to unlock in the open position of the door leaf after locking, this can be implemented via a mechanical mechanism or an electromechanical device become. In addition, intermediate locking positions at different heights are possible, depending on how the door is used. Such an embodiment of the locking device 1 can be used in doors that are designed as a sectional door with several door elements connected to one another in an articulated manner. It can also be used with spiral doors or roller doors. Because the locking device 1 is not visible from the outside, tampering can also be ruled out because the locking plate 18 with the holding piece 21 is securely embedded in the running profile 2 .
