The invention relates to a system for interlocking and unlocking a sliding door.
2. Description of the Related Art
Sliding doors, equipped with a handle in order to interlock or unlock the sliding door by a movement of the handle, are known in the state-of-the-art. It is disadvantageous in these handles that they protrude like a projection from the plane of the sliding door, whereby the user risks colliding with the handle. In addition, it has been proven that the overall construction for interlocking and unlocking the sliding door is too complicated. In particular with very thin doors, which, e.g. in their closed location, completely disappear in a wall channel, the handles known from the state-of-the-art can not be employed or incorporated on account of their complexity. In other words, this means that known systems for interlocking and unlocking the sliding door feature certain dimensions, which, in particular with very thin doors having a small door thickness, such as for example glass doors, can not be utilized.
Furthermore, it has been proven that the ease of actuating a sliding door, in particular for interlocking and/or unlocking the sliding door needs to be improved.
An object of the present invention is to avoid the above mentioned disadvantages, in particular to provide a system for interlocking or unlocking a sliding door, wherein the system is suitable to be incorporated into doors having a small thickness, whereby simultaneously the ease of operation of the system is improved.
The problem of the present invention is solved by, in one aspect, a system for interlocking and unlocking a sliding door, provided with a handle, which can be attached essentially flush-mount to the sliding door, with an electro-mechanical locking mechanism attachable in a wall-mount manner, which has a movable locking element, movable between a protracted locking position and a retracted releasing position, with an electronic drive, incorporated into the locking mechanism and in operative connection with the locking element, wherein the handle is manually movable between an opening position and a closing position, in which the handle and the locking mechanism cooperate in such a way that, in the locking position of the locking element and in the closing position of the handle, a movement of the sliding door from a closed location in the direction of the opening location can be blocked and, in the opening position of the handle, a movement of the sliding door can be effected from a closed location in the direction of the opening location, and with at least one manually accessible sensor module, which has a defined detection area, the electronic drive being in data communication with the sensor module such that a detection of a user in the detection area can move the locking element into at least one of its positions.
One essential advantage of the invention is that the handle, including its mechanism, which is incorporated within the sliding door, has a flat and/or narrow overall construction, which thus can be in particular advantageously utilized with small door thicknesses. The locking mechanism is disposed on a wall such that in particular the movable locking element is positioned such as to be movable on the wall side, and, depending on its position, to enable a movement of the sliding door, respectively to block a movement of the sliding door. The flush-mount embodiment of the handle favors the provision that no protruding components are present at the sliding door. On the one hand, via a movement by hand, the inventive system is suitable to manually effect a movement of the sliding door from the closed location in the direction of the opening location. Additionally, the invention comprises the fact that the locking element can be brought into its respective position by the manually accessible sensor module. In other words, the user can move into the detection area of the sensor module and will be detected by the sensor module. The electro-mechanical locking mechanism receives corresponding information from the sensor module, in particular a signal that the user entered the detection area such that the electronic drive can move the locking element into one of its two positions. The sensor module may be disposed, e.g., on one side of the sliding door. It is likewise conceivable that respectively one sensor module is disposed on either side of the sliding door.
Advantageously, the inventive system has a control unit, which is in signalling communication with the at least one sensor module. It is for example conceivable that the control unit issues preferences specifying which one of the two sensor modules can be activated by the user. The invention may comprise, for example, the provision that from that side of the sliding door, from where an interlocking was performed, an unlocking can be carried out only by the sensor module. As an alternative and/or in addition, it is, for example, conceivable that exclusively authorized individuals can perform an activation of the sensor module. It is conceivable in this context that an authentication query between the inventive system, in particular the sensor module and the user occurs prior to activating the electro-mechanical locking mechanism, in order to correspondingly move the locking element.
Advantageously, the sensor module may feature a touch sensor and/or a proximity sensor, in particular that the sensor module is configured to recognize at least one defined pattern of movement of the user. The touch sensor may comprise e.g. a piezo-electric sensor such that the sensor module is able to detect a contact. The proximity sensor may detect an approach to the sensor module in a capacitive manner. Other sensors, for example optical sensors, are likewise conceivable to recognize the user in the detection area. Furthermore, the sensor module may be configured in that exclusively defined patterns of movement are necessary in order to be able to activate the locking mechanism accordingly for moving the locking element into its respective position. The sensor module may be disposed, e.g., on the wall side. The inventive system comprises likewise the provision that the sensor module is disposed at the sliding door, in particular in the vicinity of the handle. It is likewise provided in the inventive system that the sensor module is incorporated into the handle and/or into the locking mechanism.
Advantageously, the handle can be disposed in the area of the sliding door which faces the locking mechanism disposed on the wall side. The handle is configured, e.g., with a knob which the user can operate. The knob may be configured as a sliding knob or else as a rotary knob. Advantageously, the knob is disposed in a knob depression of the handle such that the handle is disposed almost flush, in particular flush-mount at the sliding door. Thus, a compact overall construction can be created at the sliding door. The inventive system may be configured in that the handle can be operated from both sides of the sliding door. This means that respectively one handle with a knob is provided on either side of the sliding door. By operating the knob, the handle is manually movable between the opening position and the closing position. In the opening position, the sliding door can be displaced from the closed location into the opening location. This means that in the opening position of the handle, the locking element of the locking mechanism does not block a movement of the sliding door.
According to the invention, the system may be configured in that the handle and the locking mechanism cooperate such that in the locking position of the locking element a transfer of the handle into the opening position can be effected, whereby a movement of the sliding door from the closed location into the opening location is enabled. The particularity of this embodiment resides in the provision that the locking element can remain in the locking position in order to move the sliding door in the direction of the opening location. For this purpose, it is sufficient to transfer the handle into the opening position. In an alternative embodiment, an inventive system comprises the provision that, exclusively in the releasing position of the locking element, the sliding door can be moved in the direction of the opening location, wherein prior to this, the handle is to be moved into the opening position.
In a measure enhancing the invention, sensory electronics may be provided which recognize the position of the handle, whereby, depending on the position of the handle, the locking element can be electronically moved between the locking position and the releasing position. It is for example conceivable that the sensory electronics feature a micro-switch, which can be operated by moving the handle. The invention likewise comprises the provision that the sensory electronics feature a magnetic element, which is in particular disposed at the handle, wherein the sensory electronics feature a sensor element which is suitable to detect the position of the magnetic element. According to the invention, it is conceivable that the sensor element consists of a magnetic switch or of a Hall sensor. The advantage of the sensory electronics resides in the fact that a reliable recognition of the position of the handle can be performed.
Furthermore, it may be provided according to the invention that the handle is mechanically connected to a movable lever element, which, in the closed position of the handle, is blocked by the locking element in the locking position and prevented from moving, together with the sliding door, from the closing position in the direction of the opening position. Advantageously, the lever element is located within the handle in the area which is not visible for the user. By a movement of the handle, the lever element can be moved from a locking position into a releasing position and vice versa. In the blocking position of the lever element, the locking element blocks a movement of the sliding door from the closing position into the opening position. In the releasing position of the lever element, the lever element is spaced apart from the locking element, which is in its locking position, such that a movement of the sliding door from the closing position into the opening position is possible. Advantageously, by a movement of the handle into its respective position, the lever element is movable while pivoting about an axis.
Advantageously, the lever element may have a crescent-shaped contour at which the handle engages during its movement. The inventive system comprises for example the provision that the handle features a cam, which cooperates with the crescent-shaped contour such that, by a movement of the cam of the handle, the cam slides along the crescent-shaped contour and simultaneously moves the lever element in the direction of the blocking position and/or of the releasing position.
Advantageously, at the side facing the locking element, the lever element has a contact surface, which, in the closing position of the handle, engages, in particular contacts the locking element, if the latter is in the locking position. The contact surface forms an abutment for the locking element, if, in the closing position of the handle, the sliding door is moved in the direction of the opening location. It is only once the locking element is located in the releasing position, that the path for the contact surface is clear, in order to move the sliding door with the handle in the direction of the opening location. Advantageously, the contact surface together with the lever element form one common component, in particular a monolithic component. Due to reasons of stability, it is advantageous that the lever element be configured from a metal. The lever element may be for example a stamped metal part.
Furthermore, the inventive system comprises the provision that the handle is in such an operative connection with the lever element that, in the opening position of the handle, the lever element is disengaged from the locking element which is located in the locking position, such that a movement of the sliding door from the closed location into the opening location can be performed. Thus, it is conceivable that, in the opening position of the handle, the contact surface of the lever element is so far spaced apart from the locking element that the sliding door can be moved from the closed location into the opening location.
Furthermore, the inventive system may comprise a locking mechanism with a support element, at which the drive is disposed, wherein the drive is in operative connection with a movable bracket. The support element serves the purpose of disposing the electronic drive within the locking mechanism in a space-saving manner. The movable bracket is in operative connection with the locking element such that the locking element can be simultaneously moved along with a movement of the bracket, whereby the transfer of the locking element from the locking position into the releasing position can be realized and vice versa.
Advantageously, it may be provided that the bracket is connected to the support element via a cam, which is in operative connection with the drive, wherein in particular the bracket features a first guiding contour and the support element features a second guiding contour, wherein the cam is supported to be movable in both guiding contours. The bracket is moved by the movement of the cam, whereby the locking element is brought into its corresponding position. The cam represents a reliably functioning structural component within the locking mechanism, in order to transfer the force from the drive onto the bracket, in particular onto the locking element in a low-noise as well as a low-wear manner.
The two guiding contours may be, e.g., oblong holes, which are machined into the bracket and/or into the support element. Advantageously, the guiding contours feature a linear extension, wherein the geometrical dimensions of the guiding contours match the geometry of the cam such that the cam is able to reliably slide back and forth within the two guiding contours. Advantageously, the second guiding contour is oriented to be slanted with regard to the first guiding contour. It is thereby achieved that, in the activated condition of the electronic drive, the cam moves in both guiding contours of the bracket, respectively of the support element, wherein only the bracket moves in relation to the support element, whereby the locking element can be moved between its locking position and the releasing position. Advantageously, the support element together with the drive remains rigid and immobile in its position.
In a measure enhancing the invention, the bracket may be supported to be rotatable about an axis, wherein in particular the axis is disposed at the side of the bracket facing away from the locking element. In another embodiment of the invention, for the purpose of an emergency unlocking, the bracket may be pivotable together with the support element. It is conceivable in this case, that the bracket, as well as the support element are pivotable about their common axis. An emergency unlocking may be necessary, e.g., in case, in the opening location of the sliding door, the locking element is in the locking position and operating the electronic drive for moving the locking element is not possible. A power failure may require, e.g., an emergency unlocking. In the opening location of the sliding door, the user may push the protruding locking element manually in the direction of the releasing position, wherein simultaneously the bracket as well as the support element are moved along within the locking mechanism, and namely so far until the locking element is located in the releasing position. In the event of an emergency unlocking, the cam remains immobile in the position within the guiding contours of both the bracket and the support element. Subsequently, the sliding door can be moved into the closed location because the locking element does not cause any collision with the sliding door, in particular not with the handle.
An end piece, which features a ramp, that is in particular oriented towards the locking element, may be provided in the area of the contact surface of the lever element. The end piece is configured in the shape of a door latch-bolt. In the event of an emergency unlocking, the end piece has the function of allowing the sliding door to be displaced in the direction of the closed location and that, in a defined position of the sliding door, the slanted end piece reaches contact with the locking element which is located in the locking position. Upon further movement of the sliding door into the closed location, the slanted end piece pushes the locking element further in the direction of the releasing position, wherein simultaneously the bracket and the support element pivot within the locking mechanism. In one possible embodiment of the invention, the end piece is attached to the lever element, which means that both structural components may be configured from different materials. It is conceivable that both the end piece and the lever element may be a two-component structural part. The end piece may be configured, e.g., from a plastic material, wherein the lever element may be formed from a metallic material. The application of an end piece made from plastic material will allow for a low-noise cooperation with the locking element.
In one embodiment of the inventive system, a reception is provided in the bracket on the side of the locking element, in which reception the locking element is retained. The reception may be open on one side for example, in order to guide the locking element into the reception. A cost-advantageous mounting and/or dismounting is thereby made possible. In order to increase the ease of operation of the inventive system even more, at least one indicator may be provided which displays information on whether the locking element is located in the locking position and/or in the releasing position. The indicator provides visual information to the user on the current condition of the inventive system, in particular on the fact whether the inventive system is in the interlocking condition or in the unlocking condition. The indicator may communicate the respective information to the user by colors, in particular the color green could represent the unlocking condition and the colour red could indicate the interlocking condition of the locking mechanism. As an alternative and/or in addition, it may be provided that the handle has an indicator as well, which displays information on whether the handle is in the closing position thereof and/or in the opening position. Corresponding to the indicator of the locking element, the indicator of the handle may function analogously with colours. The inventive system likewise comprises that the indicator offers information to the user which, via numerals and/or letters and/or pictograms and/or images, provide a statement with regard to the interlocking and/or unlocking conditions of the sliding door, in particular of the handle and/or the locking mechanism.
Advantageously, the handle is configured as a rotary knob. Furthermore, the rotary knob is advantageously disposed on the inside of the sliding door. A potential mechanical emergency unlocking option may be provided for the exterior area of the sliding door, in that, instead of the rotary knob, an auxiliary contour is present, which is accessible from outside. The auxiliary contour can be moved by a suitable tool, whereby the same mechanical effect can be achieved within the handle as would be by actuating the handle from the interior area of the sliding door. The auxiliary contour may be configured for example as a slot, in which for example a coin can be inserted in order to move the slot, whereby the lever element disposed in the handle is correspondingly moved. The mechanical emergency unlocking from the exterior area of the sliding door can thus be achieved by the auxiliary contour.
