Description

The following invention relates to a locking device for locking a door leaf in a locking position between an open position and a closed position, wherein the door wing by means of a sliding member which engages longitudinally displaceable in a guide rail, between the open position and the closed position is movable feasible. Furthermore, the invention relates to a guide rail for guiding a door leaf between an open position and a closed position, comprising at least one corresponding locking device.

Locking devices for door wings are known in principle. Some locking devices are placed directly in a guide rail in which a slider is longitudinally slidably received to determine the movement of the door leaf between an open position and a closed position. Such a locking device is, for example, from the DE 196 96 294 C1 known, which can be brought by means of an electromagnet with an armature into operative connection with the sliding member to hold the slider. It has proved to be a disadvantage that the locking device is not traversable. Furthermore, it is disadvantageous that only one position of the door leaf is thus detectable. Furthermore, it is disadvantageous that the locking device fully occupies the guide rail in cross section. If, for example, the door leaf has been fixed in a locking position between an open position and a closed position, it can not be moved further into the outermost open position. When transporting bulky objects, for example when moving, this can lead to difficulties.

It is the object of the present invention, at least partially to overcome the disadvantages described above in a locking device for detecting a door leaf in a locking position between an open position and a closed position. In particular, it is an object of the present invention to provide a locking device for locking a door in a locking position between an open position and a closed position, which is simple and constructed with few components, which allows a cost-effective and easy mounting of the locking device in a guide rail on a door frame and which has an extended functionality.

The above object is achieved by a locking device with the features of independent claim 1, in particular from the characterizing part, and by a corresponding guide rail with the features of independent claim 10, in particular from the characterizing part. Further features and details of the invention will become apparent from the dependent claims, the description and the drawings. In this case, features and details that are described in connection with the locking device according to the invention apply, of course, also in connection with the guide rail according to the invention and in each case vice versa, so with respect to the disclosure of the individual aspects of the invention always reciprocal reference is or may be.

The invention provides a locking device for locking a door leaf in a locking position between an open position and a closed position, wherein the door leaf by means of a sliding element which engages longitudinally displaceable in a guide rail between the movable position and the closing position is movable, comprising: an electromagnet with an armature, which can be brought into mechanical engagement with the sliding member for locking the door leaf to stop the door in the locking position between the open position and the closed position, wherein in an operating condition of the electromagnet, the sliding element in the guide rail is lockable, and in a resting state of the electromagnet, the sliding element in the guide rail is freely movable. For this purpose, it is provided according to the invention that the electromagnet has a flat base which can be arranged in an upper functional space of the guide rail so that the slider is movable in the operating state of the electromagnet in a lower guide space of the guide rail past the locking device to the door to transfer the locking position to the open position.

The guide rail can be arranged on a door frame and have a horizontal orientation. The sliding element can cooperate with a lever element which is rotatably connected to the sliding element. Another end of the lever element may be rotatably mounted on the door leaf. At this end, the lever element may also be rotatably connected to a drive or with an at least partially automatic device for driving the door leaf between the open position and the closed position. The sliding element can slide longitudinally displaceable in the guide rail and thus support the door wing in its movement between the open position and the closed position. Furthermore, it is conceivable that the sliding element designed spring-loaded and can be guided by a spring.

The guide rail can have two spaces, an upper functional space for receiving the locking device according to the invention and a lower guide space for guiding the sliding element. The slider can slide back and forth past the locking device with the electromagnet turned off. When the solenoid is switched on, the sliding element can only slide in the direction of the locking position into the open position of the door leaf past the locking device. From the outermost open position of the door leaf, however, the sliding element does not pass the locking device, at least as long as the electromagnet is in the operating state.

In this case, in the state of rest of the electromagnet, the armature can be stowed completely within the functional space in order not to enter the guide space and not to impair the movement of the sliding element therein. In the operating state of the electromagnet, the armature can at least partially engage in the guide space and / or at least come from one side on the sliding element to rest in order to prevent the movement of the sliding element from the locking position to the closed position. The armature may in turn be only as a transmission member to a blocking element which can engage in the guide space when the electromagnet is turned on to hold the sliding element at least from one side.

The inventive idea lies in the fact that the electromagnet is designed in such a way and has such a flat body that the electromagnet occupies only an upper part of the guide rail in the functional space, and that in the idle state of the electromagnet, the slider can move unhindered below the electromagnet, namely towards and back past the locking device. Thus the advantage can be achieved that the locking device is traversable. Furthermore, it is advantageous that thus several different positions of the door leaf can be made detectable. For this purpose, in each case a locking device according to the invention would have to be arranged in a corresponding position in the guide rail. Moreover, it is advantageous that the locking device leaves enough space in the guide rail to leave the slider past the locking device. In addition, the locking device can be retrofitted due to their size in existing guide rails to upgrade the guide rails. For example, if the door leaf has been locked by the locking device according to the invention in the locking position, which is between the open position and the closed position, the door leaf can be freely moved to the open position, regardless of the state of the electromagnet. When transporting bulky objects through a door opening, a user, for example, a relocation helper, without having to park the objects to be transported, press the door, for example. With a shoulder, in the direction of the open position.

Thus, an improved locking device for locking a door leaf is provided in a locking position between an open position and a closed position, which has a simple structure with few components that allows cost-effective and easy mounting of the locking device in a guide rail on a door frame and the extended functionality has, because the locking position is traversable.

Furthermore, the invention may provide for a locking device, that the base body has a height which is about 25% to about 50%, preferably about 40% of the height of the guide rail, and / or that the base body has a length which is about 2 to about 10, preferably about 7 times greater than its height. In this case, the invention recognizes that although the installation space in the guide rail is limited in the vertical direction, it is not limited in the horizontal direction along the guide rail. To exploit the space within the guide rail, the electromagnet can be pulled in length, whereby the height of which can be reduced. Thus, a sufficient holding force for the sliding element can be generated over the length of the electromagnet, which can be arranged in the upper functional space of the guide rail on the small height of the electromagnet. Thus, the sliding element can travel below the electromagnet in the lower guide space of the guide rail without the electromagnet being in the way of the sliding element. Only in the operating state of the electromagnet, the armature can be controlled so as to act on a blocking element or even at least partially penetrate into the guide space and stop the slider from only one side of the guide rail.

Furthermore, the invention may provide for a locking device, that the electromagnet is designed as a magnet. A magnet advantageously has a limited locking width. This is advantageous to influence the sliding element only in an immediate approach to the locking device. In addition, a limited Feststellweite advantageous to the electronic and / or electrical components of the door, such. As a drive and / or various sensors and / or a control unit, not to affect in their operation.

Furthermore, the invention may provide for a locking device that the electromagnet of at least two adjacent arranged coils is composed. Thus, the advantage can be achieved that the holding force of the electromagnet to a special design of the door leaf, the frame-side guide rail, a drive and / or a place of use of the door set, for example. Enlarged, can be. Thus, basically identical locking devices for different applications can be provided, which can be assembled in the manner of a kit to set a desired holding force depending on the number of coils arranged side by side. With a certain size and number of coils, a magnetization may occur in the electromagnet. Advantageously, this number of coils can be preferably used to set a maximum holding force for a given size of the individual coils.

In addition, the invention can provide for a locking device, that the electromagnet has at least one electrically insulating cover plate at the end, in order to design a magnetic flux and to determine a locking range of the electromagnet. Thus, the advantage can be achieved that the locking range of the electromagnet can be set to a specific, possibly application-specific width. With an axially arranged cover plate also the penetration depth of the electromagnetic field can be influenced in the anchor. Advantageously, this can be realized by a magnet, which generates an attractive force only over a certain Feststellweite. Thus, the effect of the electromagnet can be controlled. In addition, it can thus be prevented that the magnetic field undesirably affects electronic and / or electrical components which are arranged in the vicinity of the locking device.

In addition, the invention can provide for a locking device, that the armature sleeve-like, preferably with an anchor plate and a jacket member is formed to axially and at least partially confine the electromagnet radially. In particular, in the case of an adhesive magnet, this can be advantageous in order to increase the holding force despite a small locking width. Thereby, a reliable hold for the sliding member can be provided at a precisely set position in the guide rail.

Furthermore, the invention may provide for a locking device that the electromagnet or the armature has a, preferably resiliently loaded with a release force and / or elastic plunger to the armature when transferring the electromagnet from the operating state in the idle state against a residual magnetization in the armature of Solenoid to solve. Thus, the advantage can be achieved that a dissolution of the effect of the electromagnet can be done on the anchor immediately or quickly. As a result, the operation of the locking device can be improved and the user friendliness can be increased.

Furthermore, the invention can provide for a locking device, that the electromagnet has a coil whose turns are arranged around a vertical axis of the electromagnet or the guide rail. Thereby, the advantage can be achieved that an almost arbitrarily high holding force can be realized regardless of a low, available height. In this case, the space along the guide rail can be utilized almost indefinitely to arrange the windings of the electromagnet about a vertical axis of the guide rail or the. In this case, a holding force is generated which extends perpendicular to the extension direction of the guide rail. To the holding force on To transfer the anchor, the armature can be arranged below the electromagnet. But this is readily possible because the windings of the electromagnet claim only a small space in the horizontal.

Advantageously, the armature may have a planar body which is arranged parallel to the longitudinal extension direction of the electromagnet. As a result, the holding force of the electromagnet with turns around a vertical axis of the electromagnet is optimally transmitted to the armature. To stop the movement of the armature along the guide rail, the holding force of such an electromagnet acts as a frictional connection. With a corresponding number of turns and a correspondingly long anchor, the frictional engagement can realize a reliable holding force on the armature. Thus, not only the available space within the guide rail can be exploited in an advantageous manner, but a holding force can be provided without a magnetization.

Furthermore, the invention can provide for a locking device that the electromagnet is designed as a rotor of a linear motor to actively control the movement of the armature. Active means that the position of the armature can be adjusted variably in both directions and preferably steplessly. Furthermore, thus, as desired and depending on the position of the door a continuously adjustable holding force can be realized. Thus, for example, at low opening angles of the door leaf, which also generate a low closing force on the door, also a small holding force for the armature sufficient to reliably hold the slider in the corresponding position within the guide rail. At relatively wide opening angles of the door, which is a correspondingly higher Generate closing force on the door, the holding force can be increased to ensure that a user while passing the door can push this even further in the open position, the door, however, even with momentum, stops at the locking device without accidentally fall and the Hurt users.

In addition, it is within the scope of the invention in a locking device conceivable that the electromagnet has a housing which is designed as a magnetic yoke body. As a result, the magnetic flux can be designed and steered to generate a precise action of the electromagnet.

Further, the object of the invention is achieved by a guide rail for guiding a door leaf between an open position and a closed position, comprising at least one locking device for locking the door leaf in a locking position between the open position and the closed position, which may be formed as described above. In this case, the same advantages are achieved, which were described above in connection with the locking device according to the invention, to which the present reference is made in full.

a schematic representation of a guide rail according to the invention.

In the different figures, the same parts of the locking device 10 and the guide rail 200 are always provided with the same reference numerals, which is why they are usually described only once.

The Figures 1a, 1b and 1c show a door 100 first in a closed position I in the view of FIG. 1a , then in a locked position II in the view of FIG. 1b and finally in an open position III in the view of Figure 1c , In the open position III, the door 100 is pivoted the farthest.

Based on Figures 1a, 1b and 1c it is apparent that a locking device 10 according to the invention is provided on a guide rail 200 for guiding a Gleisteins 20. How it in particular the Figure 1c shows the locking device 10 according to the invention is traversable for the sliding member 20 in the direction of the locking position II in the open position III. From the locking position II in the closed position I, the locking device 10 with a switched-off electromagnet 11 can be moved over. When the electromagnet 11 is turned on, the locking device 10 holds the slider 20 in a corresponding position in the guide rail 200 to stop the door 100.

The guide rail 200 may be arranged on a door frame 101 and have a horizontal orientation. The sliding member 20 may cooperate with a lever member 30 which is rotatably connected to the sliding member 20. Another end of the lever element 30 may be rotatably mounted on an at least partially automatic device, not shown, for actuating the door leaf 100. The sliding member 20 can slide longitudinally displaceable in the guide rail 200 and thus support the door leaf 100 in its movement between the open position III and the closed position I. Furthermore, the sliding member 20 may be spring loaded, for example. From left to right in the view of FIGS. 1a to 1 c.

The locking device 10 according to the invention is the FIG. 2 shown. The locking device 10 is used to lock the door leaf 100 in the locked position II (s. FIG. 1 b) between the open position III (s. Figure 1c ) and the closed position I (s. FIG. 1a ) lies. The door leaf 100 can be guided by means of the sliding element 20 between the open position III and the closed position I, which engages in the guide rail 200 in a longitudinally displaceable manner. The locking device 10 according to the invention comprises an electromagnet 11 with an armature 12 which is in mechanical operative connection with the sliding element 20 for locking of the door leaf 100 can be brought to stop the door 100 in the locking position II between the open position III and the closed position I. Here, the sliding member 20 in an operating state 1 of the electromagnet 11, which exemplifies in the FIG. 1b is shown in the guide rail 200 lockable. In a rest state 2 of the electromagnet 11, the sliding member 20 in the guide rail 200 is freely movable. The idle state 2 of the electromagnet 11 may, for example. In the FIG. 1a be accepted. In the Figure 1c For example, the electromagnet 11 can be in both operating state 1 and in rest state 2. In the operating state 1 or in the idle state 2, the electromagnet 11 can be transferred by actuating a common and / or in each case a switch, not shown, which / can be arranged, for example, in the guide rail 200 / can. The operating state 1 of the electromagnet 11 is exemplified by a solid line in the Figure 3c shown, wherein the idle state 2 of the electromagnet 11 with a dashed line in the Figure 3c is indicated.

The FIG. 2 shows that the electromagnet 11 has a flat main body M, which can be arranged in an upper functional space 201 of the guide rail 200, so that the slider 20 is movable in the operating state 1 of the electromagnet 11 in a lower guide space 202 of the guide rail 200 past the locking device 10, to transfer the door 100 from the locking position II to the open position III.

As the FIG. 2 clarified, the guide rail 200 is divided into two spaces 201, 202, namely the upper functional space 201 for receiving the locking device 10 of the invention and the lower guide space 202 for guiding the sliding member 20. The height of the functional space 201 can be approximately the height of Guide space 202 correspond. In this case, the sliding member 20 when the electromagnet 11 back and forth past the locking device 10 slide. When the electromagnet 11 is switched on, the sliding element 20 can only slide in the direction of the locking position II into the open position III of the door leaf 100 past the locking device 10. From the outermost open position III of the door leaf 100, however, the sliding element 20 does not pass the locking device 10, at least as long as the electromagnet 11 is in the operating state 1 (see the view of FIG FIG. 1 b) located.

In this case, in the resting state 2 of the electromagnet 11 of the armature 12, in the Figure 3c is shown schematically, cause a not-shown locking element, completely immersed within the functional space 201 so as not to enter the guide space 202 and the movement of the sliding member 20 is not affected therein. In the operating state 1 of the electromagnet 11, the armature 12 can cause the blocking element at least partially engages in the guide space 202 and / or at least from one side on the sliding member 20 comes to rest, to the movement of the sliding member 20 from the locking position II in the closed position I prevent.

The FIG. 2 illustrates the concept of the invention, according to which the electromagnet 11 is designed with a flat body M, that the electromagnet 11 occupies only the upper functional space 201 of the guide rail 200, and that in the rest state 2 of the electromagnet 11, the slider 20 unhindered below the electromagnet 11 over the locking device 10 can proceed. Thus, the locking device 10 can be designed to be overridden. Thus, several different positions of the door leaf 100 can be realized detectable by a respective inventive Locking device 10 can be arranged in a corresponding position in the guide rail 200. In addition, the locking device 10 due to their size even later in existing guide rails 200 can be mounted to upgrade the guide rails 200 according to the invention. If, for example, the door leaf 100 has been determined by means of the locking device 10 according to the invention in the locking position II, as it FIG. 1b shows, the door 100 can be moved freely in the open position III, regardless of the state of the electromagnet 11. When transporting scanty objects through a door opening, a user, for example, a relocation helper, without having to park the objects to be transported, the Press door leaf 100, for example with one shoulder, in the direction of open position III.

Like the Figures 3a, 3b and 3c show in a perspective, a frontal and a side view of the main body M, the main body M may have a height h, which is about 25% to about 50%, preferably about 40% of the height H of the guide rail 200. In addition, the main body M may have a length I which is about 2 to about 10, preferably about 7 times greater than its height h. Thus, the base body M can be received in the functional space 201 of the guide rail 200, although the space in the functional space 201 is limited in the vertical direction z, but not in the horizontal direction x along the guide rail 200. The main body M may further have a width b, which is slightly smaller than the width of the guide rail 200. In this case, the electromagnet 11 can be pulled into the length I in order to reduce its height h. Thus, over the length I of the electromagnet 11, a sufficient holding force F are generated for the sliding member 20, wherein on the small height h of the electromagnet 11 he in the upper functional space 201 of the Guide rail 200 can be arranged. Thus, the sliding member 20 can proceed unhindered below the electromagnet 11 in the lower guide space 202 of the guide rail 200 without the electromagnet 11 is the sliding member 20 in the way. In the operating state 1 of the electromagnet 11, furthermore, the armature 12 can be controlled in such a way that the sliding element 20 is stopped within the guide rail 200.

It is also conceivable within the scope of the invention that the solenoid 11 may be designed as a pure magnet to generate an adjustable locking width w and stop the slider 20 only at an immediate approach to the locking device 10, without further electronic components of the door 100 affect.

As is the case with the FIGS. 3a and 3b and in the following the FIGS. 4 to 9 show, the electromagnet 11 may have a magnetic core 18. Furthermore, it is conceivable that a housing 19 may be provided for the electromagnet 11, which may be formed according to an embodiment of the invention as a magnetic yoke body.

As it further the FIG. 4 shows, the electromagnet 11 according to an embodiment of the invention from at least two juxtaposed coils S1, S2, S3, S4 be composed. The FIG. 4 shows only by way of example four juxtaposed coils S1, S2, S3, S4. With a variable number of S1, S2, S3, S4, the holding force F of the electromagnet 11 can be set stepwise, for example, increased. This may be advantageous to the locking device 10 according to the invention with different versions of the door leaf 100, the frame-side guide rail 200, a drive and / or a location of use of the door leaf 100 to use. In this way, a multi-model locking device 10 can be provided for different applications, which can be assembled in the manner of a kit.

As it continues the FIG. 5 shows, according to a further embodiment of the invention, the electromagnet 11 may have at least one electrically insulating cover plate 13 at the end, in order to design a magnetic flux m and to design a locking width w of the electromagnet 11 (cf. FIG. 6 ). In addition, thus, at least partially, the penetration depth of the electromagnetic field in the armature 12 can be influenced. Advantageously, this allows a pure magnet to be realized.

As it further the FIG. 6 shows, the armature 12 according to an embodiment of the invention, sleeve-like, preferably with an end-side anchor plate 14 and a circumferential, cylinder jacket-shaped jacket member 15 may be formed to axially and at least partially confine the electromagnet 11 radially. Thus, the holding force F of the electromagnet 11 can be increased even at a small locking width w.

As is the case with the FIG. 7 shows, according to a further embodiment of the invention, the electromagnet 11 or the armature 12 may have a plunger 16 to release the armature 12 from the electromagnet 11 during the transfer of the electromagnet 11 from the operating state 1 in the rest state 2 against a residual magnetization in the armature 12.

Like the FIG. 8 in the following shows, the plunger 16 can be acted upon resiliently with a release force L to facilitate release of the armature 12 from the electromagnet 11 during transfer of the electromagnet 11 from the operating state 1 in the rest state 2 against a residual magnetization in the armature 12. Thus, a fast switching of the locking device 10 can be made possible.

The FIG. 9 shows yet another embodiment of a locking device 10 with an electromagnet 11 having a coil 17, whose turns are arranged about a vertical axis z of the electromagnet 11 and the guide rail 200. Thereby, the space along the guide rail 200 can be exploited in an advantageous manner. In this case, a holding force F is generated, which extends perpendicular to the extension direction x of the electromagnet 11 and the guide rail 200. In order to transmit the holding force F to the armature 12, the armature 12 may be disposed below the electromagnet 11. In this case, the armature 12 may have a planar body A, which may be arranged parallel to the longitudinal extension direction x of the electromagnet 11 or the guide rail 200. As a result, the holding force F of the electromagnet 11 with windings about its vertical axis z can provide a frictional connection for the armature 12. With a corresponding number of turns and with a correspondingly long armature 12, the frictional engagement can exert a reliable holding force F on the armature 12. With a growing number of turns advantageously a holding force F can be provided without magnetization.

Furthermore, the shows FIG. 10 Yet another embodiment of the invention, according to which the electromagnet 11 as a rotor of a linear motor may be formed to actively control the movement of the armature 12. In this embodiment, the electromagnet 11 and the armature 12 move together. Thereby, the position of the armature 12 can be variably and steplessly adjusted in both directions together with the position of the electromagnet 11. Thus, depending on the desire and depending on the position of the door 100, a continuously adjustable holding force F can be realized. Thus, the capabilities of the locking device 10 can be extended.

The FIG. 11 finally shows a door system with a door 100, which is pivotally mounted on a door frame 101. On the door frame 101, a guide rail 200 according to the invention for guiding the door leaf 100 between an open position III and a closed position I can be arranged, comprising at least one locking device 10 for locking the door leaf 100 in a locked position II between the open position III and the closed position I, as above based on the FIGS. 1a to 10 may be formed described.

The above description of FIGS. 1 to 11 describes the present invention solely in the context of examples. Of course, individual features of the embodiments, insofar as it is technically feasible, can be freely combined with one another without departing from the scope of the invention.
