The present invention relates to means and methods for fixing a movable object, such as a door or window, to a frame. In particular, the present invention provides a magnetic locking system configured for releasably fixing a movable object to the frame.
A sliding door or window supporting system consists of a stationary frame that is provided with a guide over which a sliding door or window can slide to and fro, for example by means of bearings or rollers. On one side of the frame, a locking mechanism may be mounted, to lock the sliding door or window. With modern sliding doors or windows, a hook lock is often chosen, by which the door can hook onto the frame. A typical hook lock consists of a movable component that is provided with a hook part that can engage on a locking mechanism that is mounted on an inner wall of the frame. There are also other kinds of locking mechanisms, but regardless of the choice there is generally a lack of user-friendliness and flexibility. The user must first close the door completely before the locking mechanism can be put into operation. For modern devices it is advantageous to secure the door or window at various positions along the guide, for example when several sliding doors or windows are connected together.
Flexible locking may for example be achieved by providing several locking mechanisms in the frame, but then the user will be required to seek out repeatedly a correct door or window position at which the opening overlaps with the movable component of the locking mechanism. Carrying out such operations will be considered by a user as very undesirable. This will also increase the complexity of the system, which leads to a higher cost price.
From CN102797395A, a door locking system is known for a housing of communication equipment. The door locking system comprises four magnets, which are mounted in a groove facing the door, in a door frame, or simply frame, round the perimeter of the door. The door locking system comprises four corresponding extendable blocks, which are mounted at corresponding positions on the perimeter of the door. The door may be placed in the door frame by holding the extendable blocks in a retracted position by tightening respective cables that are connected to a handle. When the door is placed in the door frame so that the extendable blocks of the door are aligned with the door-facing groove of the door frame, the four extendable blocks can be moved together in the groove of the door frame by operating the handle so that the cables allow the blocks to slide out. Then the extendable block is attracted and held in the groove of the door frame by means of the magnets that are positioned opposite these extendable blocks. A drawback of such a system is that the door must first be aligned relative to the door frame so that the extendable blocks can go into the groove of the door frame. During this alignment, the handle has to remain activated in order to keep the blocks in the retracted position. It is only once the alignment of the blocks and the grooves has been brought about that the handle can be deactivated to allow the blocks to slide out into the groove of the door frame. Although all blocks can be operated with one handle, this still requires a complex and precise operation to allow all four blocks to align accurately with the groove of the door frame, while the operator must continue to keep the handle permanently and completely in the activated position until this alignment is achieved. Owing to the necessary alignment, reliable and robust closure is difficult to achieve, or precise alignment must be achieved between the blocks and the grooves, so that there is a risk that with insufficiently precise alignment the blocks may not go into the grooves, or a large enough tolerance must be provided, so that in the closed state there is a risk that the door can still move excessively to and fro, and for example under a high wind load will make undesirable movements, which may give rise to deformations and/or undesirable sounds such as rattling. It is also clear that the door of such a housing can only be introduced into the door frame in one position and can only be fixed in one position in the door frame by means of the door lock, namely the closed position wherein the door completely closes the door frame. It is also clear that such a door of a housing relates to a removable access door or cover and not a sliding door or hinged door. Finally, in the closed state, the movable block remains accessible via the space between the door perimeter and the door frame, which makes it difficult to prevent undesirable manipulation of the movable block, for example to prevent inadmissible access to unlock the door.
WO2014/094071A1 describes a locking mechanism for locking a door to a door frame in a closed position. The locking mechanism comprises an extendable magnetic bolt at the top and at the bottom of the door. In the closed position of the door, these magnetic bolts are aligned with ferromagnetic blocks in the door frame round the perimeter of the door. Through the force of magnetic attraction, as soon as this aligned position is reached, the extendable magnetic bolt is pushed out of the door to a locked position against the ferromagnetic blocks in the door frame. A handle that is connected with cables to the extendable magnetic bolts makes it possible to bring the bolts back to their retracted position. In other words, on activation of this handle, the coupling between the extendable magnetic bolts and the ferromagnetic blocks is broken again. In the door frame, at the level of the ferromagnetic blocks, a channel is provided in which the magnetic bolt can penetrate as far as the ferromagnetic blocks, to lock the door in the closed position. Here too there is the drawback that owing to the required alignment to bring about locking, reliable and robust closure becomes difficult to achieve, or precise alignment must be achieved between the extendable magnetic bolts and the channels for the ferromagnetic blocks, so that there is a risk that insufficiently precise alignment may not lead to locking, or a large enough tolerance must be provided, so that in the closed state there is a risk of excessive clearance in the locked state, with for example undesirable movements, deformations or undesirable sounds in consequence. Once again it is clear that the door can only be locked in one position on the door frame, namely the closed position, wherein the door is positioned in an outermost position against a stop of the door frame. Just as stated above, here too in the closed state the extendable magnetic bolt remains accessible via the space between the door perimeter and the door frame, so that a complex coupling system must be provided at the level of the connection of the cable to the extendable magnetic bolts to prevent, on closing the door, undesirable manipulation of the extendable magnetic bolt to unlock the door inadmissibly.
In US2020/0048934A1, a magnetically triggered locking mechanism is described, wherein a magnet in the door frame, when aligned with a magnet in a locking mechanism in the perimeter of the door, triggers a pretensioned extendable bolt to move from a retracted to an extended position, wherein the bolt engages in a corresponding opening in the door frame so as to lock the door. A handle can, by means of a cable, bring the extendable bolt back to the retracted, clamped position. This handle must, however, keep the extendable bolt in the clamped position until the door is far enough away from the magnetic trigger in the door frame. Here too there is the drawback that owing to the required alignment for bringing about locking, reliable and robust closure becomes difficult to achieve, or precise alignment must be achieved between the extendable bolts and the opening and the magnetic trigger in the door frame, so that there is a risk that insufficiently precise alignment does not lead to locking, or a large enough tolerance must be provided, so that in the closed state there is a risk of excessive clearance in the locked state with for example undesirable movements, deformations or undesirable sounds in consequence. Here too it is clear that the door can only be locked in one position on the door frame, namely the closed position, wherein the door is positioned in an outermost position against a stop of the door frame. Just as stated above, in the locked state the extendable bolt remains accessible via the space between the door perimeter and the door frame, so that a complex coupling system must be provided at the level of the connection of the cable to the extendable bolts to prevent, on closing the door, undesirable manipulation of the extendable bolt unlocking the door inadmissibly.
There is thus a need for the development of a new and improved locking mechanism to rectify the shortcomings of the prior art. In particular there is a need for a flexible locking mechanism with which the user can secure a sliding door or window in a frame in a simple and user-friendly way, without requiring complex operations and/or additional components. In addition, there is a need for a locking mechanism of this kind that makes more robust and reliable locking possible.
In order to satisfy the needs and shortcomings of the prior art described above, the inventors have developed methods and means for a sliding door or window supporting system. In particular, the present invention relates to a magnetic locking system for fixing a movable object, such as a sliding door or window, which is placed in a sliding guide of a frame. The locking system may be configured for a single-sided configuration, wherein a top or bottom of the object is fixed to the sliding guide of the frame, or a double-sided configuration, wherein both the top and the bottom of the object are fixed.
One aspect of the invention relates to a magnetic locking system for releasably fixing a movable object, such as a movable door or window, to a frame, the locking system comprising: at least one stop element mounted to the frame; at least one blocker mounted to the movable object, configured to be moved between: a retracted state configured to allow the blocker to move unhindered past the stop element; and an extended state configured to secure the blocker on the stop element when the blocker is moved till at the stop element; a locking mechanism mounted to the movable object and connected to the blocker, configured for selectively: in a first state, bringing and/or keeping the blocker in the retracted state; and in a second state, disconnecting the blocker to move it to the extended state, and wherein the blocker comprises a magnet and the stop element comprises a magnetically attractable material, and/or vice versa; configured so that in the extended state, the blocker is fixed to the stop element by attraction of the magnet toward the magnetically attractable material.
According to one aspect of the invention, a magnetic locking system is provided for releasably fixing a movable object, such as a movable door or window, to a frame, the locking system comprising:
In this way, robust and reliable locking can be achieved, since the movement mechanism provides improved alignment of the movable object with the stop element in the frame.
In addition, the holder of the movement mechanism shields the blocker, so that undesirable manipulation via the space between the frame and the movable object is prevented.
According to a preferred embodiment, a locking system is provided, wherein the locking mechanism further comprises:
A locking mechanism of this kind is simple to produce.
According to a preferred embodiment, a locking system is provided, wherein the movement mechanism moves within the frame. According to particular embodiments, particularly wherein the movable object comprises a sliding window or a sliding door, the frame comprises or consists of an elongated guide profile for the sliding door or the sliding window that extends in the direction of movement of the sliding door or the sliding window.
In this way, the movement mechanism can achieve good alignment of the blocker and the stop elements in a simple manner, and the movable part of the blocker is shielded by the holder and by the frame.
In a preferred embodiment, the at least one blocker is mounted to a top and/or bottom of the movable object and the at least one stop element is mounted to a corresponding top and/or bottom of the frame.
In a preferred embodiment, the at least one blocker is mounted to an upper and/or lower outer wall of the movable object and at least one stop element is mounted to a corresponding upper and/or lower inner wall of the frame.
In a preferred embodiment, the locking system comprises at least two blockers, wherein a first, upper blocker is mounted to a top of the movable object and a second, lower blocker is mounted to a bottom of the movable object; and, at least two stop elements are mounted correspondingly to a top and bottom of the frame; preferably at opposite positions.
In a preferred embodiment, the locking system comprises at least two blockers, wherein a first, upper blocker is mounted to an upper outer wall and a second, lower blocker is mounted to a lower outer wall of the movable object; and, at least two stop elements are mounted correspondingly to an upper and lower inner wall of the frame; preferably at opposite positions.
In a preferred embodiment, the stop element comprises a recess, which is configured for inserting and mechanically fixing the blocker in the extended state.
According to a particular embodiment, the stop element with the recess is preferably mounted in such a way that an edge with magnetically attractable material is located around the recess, in the direction of movement of the movable object, and is located at a smaller distance from the movable object than the recess from the stop element. According to a preferred embodiment, this edge is closer to the blocker than the recess. This offers the advantage that the distance that must be bridged over by the blocker up to the stop element is less than the distance from the recess.
According to a preferred embodiment, the stop element is configured so that on further movement of the blocker in the direction of the recess by means of a movement of the movable object along the frame, the blocker, already magnetically attracted against the stop element, on reaching the recess will go into the recess on the basis of the magnetic attraction to the stop element.
This offers the advantage of a quicker, more reliable and more robust connection, since the additional distance that must be bridged over by the blocker to this extended state is more limited than the distance between the completely retracted and the completely extended state.
According to a preferred embodiment, the connection between the blocker and the stop element is achieved by means of the movement of the movable object alone, in other words without requiring an additional action or manipulation.
According to a preferred embodiment, the distance to the recess of the blocker in the retracted state is so great that the blocker is not moved to the stop on the basis of magnetic attraction from the first, disconnected, state, when the stop is located opposite the recess. This offers the advantage that a simple locking mechanism can be used, wherein means need not necessarily be provided or a correct further operation of the locking mechanism is necessary to keep the blocker in the retracted position and then to be able to move the movable object away from the position in the frame determined by this stop.
In a preferred embodiment, the locking system comprises a plurality of stop elements, for example two stop elements, which are mounted at various positions along the length of the frame to allow the blocker to move past or up to; preferably at equal distances from each other. It is clear that according to such an embodiment the stop elements are mounted in such a way that the movable object can be locked at various positions along the length of the frame.
In a preferred embodiment the locking mechanism comprises: a tensioning cable, connected with one end to the blocker, which is configured to limit the movement of the blocker to the extended state; a tensioning mechanism that is configured to keep the tensioning cable under tension by clamping the blocker to the retracted state; and a locking component that is configured to connect the locking mechanism selectively between the first state and the second state by acting upon the tensioning cable.
In a preferred embodiment, the tensioning cable is connected with one end to a first, preferably upper, blocker and with another end to a second, preferably lower, blocker. In a preferred embodiment, the locking system comprises a pivoting body that is provided with at least one opening through which the tensioning cable runs; configured so that a rotation of the pivoting body bends this tensioning cable and thus moves the blocker to the retracted state.
In a preferred embodiment, the locking mechanism comprises, arranged between the blocker and the pivoting body, a supporting element for supporting the tensioning cable; preferably an opening or slot through which the tensioning cable runs.
In a preferred embodiment, the locking mechanism comprises a handle that is linked to the pivoting body and is configured to rotate the pivoting body.
In a preferred embodiment, the handle comprises a blocking mechanism that is configured to block the operation of the handle.
In a preferred embodiment, the locking system comprises a movement mechanism that is configured to bring about a movement of the movable object in the frame; wherein the movement mechanism comprises a holder, which has a passage with a first opening for mounting the blocker and a second opening for mounting the tensioning cable; and wherein the holder is mounted between the movement mechanism and the tensioning mechanism.
In a preferred embodiment, the tensioning mechanism comprises a spring system, such as a clamping spring, which is configured to clamp the holder against the movement mechanism.
In a preferred embodiment, the tensioning mechanism comprises an insertion slot that opens onto the spring system and/or a connecting piece that is connected to the spring system; wherein the holder comprises a stop that can be inserted in this insertion slot;
In a preferred embodiment, the stop is a flange.
In a preferred embodiment, the tensioning mechanism comprises an adjuster that is configured to adjust the distance between the tensioning mechanism and the movement mechanism by controlling the maximum tension range of the tensioning mechanism.
In a preferred embodiment, the adjuster comprises a rotatable element, such as a bolt, which when turned acts upon the spring system and/or the connecting piece.
One aspect of the invention relates to a door or window supporting system comprising: a frame and a movable object, such as a movable door or window, which is placed movably in the frame; and a magnetic locking system as described herein for releasably fixing the movable object to the frame, preferably at two or more different positions of the movable object relative to the frame.
One aspect of the invention relates to a use of a door or window supporting system as described herein as a partition, wall, door, window or closure for closing a living space, such as a balcony, veranda or terrace, preferably a sliding door or sliding window.
One aspect of the invention relates to an assembly for a movable door or window system comprising:
According to one aspect of the invention, a method is provided for assembling a magnetic locking system according to one aspect of the invention for releasably fixing a movable object to a frame, comprising the following steps:
According to one aspect of the invention, a use of a magnetic locking system according to one aspect of the invention is provided for releasably fixing a movable object to a frame.
According to a preferred embodiment, the movable object is preferably fixed releasably to the frame at two or more different positions of the movable object relative to the frame.

In order to satisfy the needs and shortcomings of the prior art described above, the inventors have developed methods and means for a door or window supporting system.

Referring to
As shown in
As described above, the pivoting body 330 can rotate between at least two states. In a first state the tensioning cable 310 will be able to run unhindered along the pivoting body 330 so that the blocker 100 is free to move from the retracted state to an extended state. In a second state the pivoting body 330 will act upon the tensioning cable 310 so that the latter is under higher tension, so that movement of the blocker 100 will be limited to the retracted state. It is clear that in this way the pivoting body 330 forms an embodiment of a locking component that is configured to switch the locking mechanism 30 selectively between the first state and the second state by acting upon the tensioning cable 310.
According to the assembly shown, the movement of the blocker 100 in the retracted state can be limited selectively between the two states described above, in particular: a first state in which the blocker 100 is free to move to the extended state; and a second state in which the blocker is held in the retracted state.
According to the assembly shown, the movement of the blocker 100 in the extended state can be adapted selectively between the two states described above, in particular: a first state in which the blocker 100 can remain in the extended state; and a second state in which the blocker will move to the retracted state.
Referring to
Movement of the blocker 100 in the recess 210 can be brought about by providing magnetic attraction between on the one hand the blocker 100 and on the other hand the stop element 200. As an example, the blocker 100 may comprise a magnet and the stop element 200 may comprise or be made of a magnetically attractable material. The magnetic attraction will thus ensure that the blocker 100 moves to the extended state, i.e. moves into the stop element 200. Then the magnetic attraction may be interrupted by bringing the blocker 100 to a retracted state by means of the locking mechanism 30 described above. According to a particular embodiment, the stop element 200 with the recess is preferably mounted in such a way that around the recess, in the direction of movement of the movable object, there is magnetically attractable material, which is located at a smaller distance from the movable object 10 than the recess from the stop element 200. It is clear that, preferably, on approach of the stop element 200, first the blocker 100 will be attracted magnetically to this edge of the stop element 200 next to the recess 210. Since this edge is closer to the blocker 100 than the recess, the magnetic attraction will be stronger, and the distance that must be bridged by the blocker 100 up to the stop element 200 will be smaller than the distance to the recess. It is clear that then, with further movement of the blocker 100 in the direction of the recess by means of a movement of the movable object 10 along the frame 20, for example such as along the longitudinal direction of the elongated profile of the frame 20 as shown in the figures, the blocker 100 already attracted magnetically toward the stop element 200, on reaching the recess 210, will enter the recess 210 more quickly and easily on the basis of the magnetic attraction to the stop element 200, since the additional distance that must be bridged over by the blocker 100 toward this extended state is also more limited than the distance between the completely retracted and the completely extended state. This offers the advantage that a connection between the blocker 100 and the stop element 200 can be achieved robustly and reliably, preferably by means of the movement of the movable object alone without requiring an additional action or manipulation. This is advantageous when the stop is used for example in an intermediate position along the longitudinal direction of a frame or guide rail of a sliding door or sliding window, since even at higher speeds of movement of the movable object 10, locking can be achieved with certainty at the desired position of the stop 200. According to a preferred embodiment, the distance to the recess 210 from the blocker 100 in the retracted state is so large that the blocker 100 is not moved to the stop 200 on the basis of magnetic attraction from the first, disconnected state, when the stop 200 is located opposite the recess 210. This makes it possible, particularly in the case of a stop 200 that is located above the blocker 100, on unlocking the magnetic locking system 50 by releasing the blocker 100 from the recess 210 in the stop 200 by bringing the blocker to the retracted state with the locking mechanism 30, the blocker 100 will not be moved back by magnetic attraction to the stop 200 as long as it is still located at the level of the recess. This offers the advantage that a simple locking mechanism 30 may be used, wherein means need not necessarily be provided or a correct further operation of the locking mechanism 30 is necessary to keep the blocker 100 in the retracted position so that then the movable object 10 can be moved away from the position in the frame determined by this stop 200.
For further explanation of the advantages and further adaptations to the invention, specific embodiments of the magnetic locking system are described in more detail hereunder. A person skilled in the art will understand that the aspects described herein may be combined with each other, unless stated otherwise. Thus, a particular embodiment of a specific aspect may also be viewed as an embodiment of another aspect without express discussion thereof. For example, an embodiment of the locking system forms also an embodiment for the production of said locking system, the use of said locking system, and so on.
One aspect of the present invention relates to a magnetic locking system for releasably fixing a movable object, such as a movable door or window, to a frame. In one embodiment, the locking system comprises at least one stop element mounted to the frame; at least one blocker mounted to the movable object, configured to be moved between: a retracted state configured to allow the blocker to move unhindered past the stop element; and an extended state configured to secure the blocker on the stop element when the blocker is moved till at the stop element; a locking mechanism mounted to the movable object and connected to the blocker, configured for selectively: in a first state, disconnecting the blocker to move it to the extended state; and in a second state, bringing and/or keeping the blocker in the retracted state, and wherein the blocker comprises a magnet and the stop element comprises a magnetically attractable material, and/or vice versa; configured so that in the extended state, the blocker is fixed to the stop element by attraction of the magnet toward the magnetically attractable material. It is clear, moreover, that according to preferred embodiments, the magnetic locking system 50 is configured for releasably fixing the movable object 10 to the frame, wherein the movable object 10 always remains connected to the frame 20. For example, with releasable fixing of a sliding door or sliding window to a frame 20, the magnetic locking system 50 is configured to fix the sliding door or sliding window releasably at one or more positions along the longitudinal axis of the frame 20, wherein in the retracted state of the blocker 100 the sliding door or sliding window may be moved in the longitudinal direction of the frame 20 past the one or more stop elements 200, and wherein in the extended state of the blocker 100, movement of the sliding door or sliding window in the longitudinal direction of the frame 20 is prevented at the level of one of the one or more stop elements 200. It is clear that, for example as shown in
The magnetic locking system described herein has the advantage that it allows reliable and user-friendly locking of a movable object without this requiring complex operations or settings. In one embodiment, the user may choose to activate the locking mechanism regardless of the present position of the object, for example when the door or window is completely or partially open, so that this will be fixed automatically during closure. In a further embodiment the user may also choose to fix the object at various positions in the frame, for example when several movable objects are connected together sequentially to achieve partial closure of the movable object.
The magnetic locking system described herein may also limit the number of movable components that are necessary to bring about locking, which reduces the complexity of the system and limits the likelihood of defects or wear. This may offer a durable solution for extending service life. In one embodiment, the locking may also be brought about more quickly and more flexibly than in systems in the prior art.
The locking system described herein may also be concealed more easily for a more aesthetic looking finish of the object and/or frame. In particular, the components of the present locking mechanism can be incorporated completely in a wall of the object and/or frame. This may give a user the impression that a continuous wall has been produced, i.e. without interruptions consisting of slots or projections. This may also improve the heat loss of the system, as there are fewer openings that promote heat transfer.
The locking system described herein can be produced in a single-sided configuration, wherein a top or bottom of the object is fixed to the frame, and a double-sided configuration, wherein both the top and the bottom of the object are fixed to the frame. The double-sided configuration may fix the object more sturdily, but logically also increases the design complexity. A person skilled in the art will appreciate that these single-sided and double-sided embodiments are illustrative, and the locking system may in principle also be adapted to more complex configurations.
In one embodiment, the present invention provides a single-sided locking system, wherein a top or bottom of the object is fixed to the frame or a guide. The single-sided locking system may comprise at least one blocker that is mounted to a top or bottom of the movable object and at least one stop element that is mounted to a corresponding top or bottom of the frame. The single-sided locking system may be provided with at least one stop element that is incorporated in the upper or lower guide of the frame, preferably in a concealed passage of the guide, corresponding to the position of the blocker in the movable object.
In one embodiment, the present invention provides a double-sided locking system, wherein both the top and the bottom of the object are fixed to the top and bottom of the frame or a guide. The double-sided locking system may comprise at least two blockers, wherein a first, upper blocker is mounted to a top of the movable object and a second, lower blocker is mounted to a bottom of the movable object; and at least two stop elements that correspond to a top and bottom of the frame are mounted. The stop elements may be incorporated at opposite positions in the frame or the guide, corresponding to the positions of the blockers in the movable object.
A frame, framing or framework as used herein refers to a rigid structure in which a movable object, such as a door or window, is placed. The frame will typically be fixed to a wall for support, so that it can close a living space, such as a balcony, veranda or terrace.
The inner wall of the frame may be provided with means for setting the movement of the movable object in operation. In one embodiment, the movable object may be provided with a sliding means that is in contact with the frame so that the object can slide relative to the frame. The frame may be provided with a guide, over which the object can move in the longitudinal direction of the frame. The object will typically move in a horizontal direction, but the present invention may also be applied for vertical sliding systems. In another embodiment the movable object may be provided with a tilting means, which is in contact with the frame so that the object can also tilt relative to the frame.
A person skilled in the art will appreciate that the locking mechanism described herein is not limited to a specific embodiment of the movement mechanism, such as the movement means or drive that is used. As an example, the locking mechanism may be employed with a suspended sliding system, wherein the movable object is “suspended” by two trolley hangers provided in the upper wall of the frame or a guide. As an example, the locking mechanism may be employed with a rolling sliding system, wherein the movable object is placed on wheels or bearings provided in the lower wall of the frame or a guide. The locking mechanism may be used both for indoor and outdoor applications.
The movable object as used herein refers to a door or window that is arranged movably in the frame. The movable object may for example be placed slidably in the frame to form a sliding door or window. The movable object may for example be placed tiltably in the frame to form a tilting door or window. A person skilled in the art will appreciate that the locking mechanism described herein is not limited to a particular embodiment of a door or window. Any reference to a door is also a reference to a window or similar movable object, and the preferred embodiments of a door described herein form equally preferred embodiments of a window. As an example, a door or window may be formed by one frame profile or several frame profiles coupled together. The object may optionally be provided with glazing.
The relative terms “left”, “right”, “in front”, “behind”, “above”, “below”, “over”, “under”, “central”, “lateral”, and the like in the present description are used for describing purposes and not necessarily for describing absolute positions. It will be understood that the terms used are mutually interchangeable in appropriate circumstances, depending on the orientation described, so that the embodiments described herein may for example also be used in orientations other than those illustrated and/or described herein. As an example, “lateral” may coincide with an upward, downward and/or sideways (for example to the left or right) position and/or direction.
The magnet relates to an object that produces a magnetic field. In one embodiment, a permanent magnet may be made from magnetic or magnetized material, such as magnetic metals or composites. A person skilled in the art will appreciate that the locking system is not limited to a specific type of magnet or magnetic material. In another embodiment, the magnet may be an electromagnet.
The blocker forms a suitable housing for a magnet, so that this magnet can be mounted movably in the movable object. The blocker may consequently also be described as a magnetic blocker. It should be clear that this is only one possible embodiment, which can easily be reversed, i.e. so that the stop element comprises a magnet and the blocker comprises a material that is suitable for being attracted by this magnet. A person skilled in the art is assumed to be capable of carrying out the necessary adjustments to the locking system described herein.
Referring to
The blocker may be made of a magnetic shielding material that blocks the magnetic field produced by the magnet so that the magnet cannot attract any nearby components of the system undesirably, such as screws. A person skilled in the art will appreciate that the provision of a blocker allows easier production and mounting of the locking system, but the magnet may in principle also be applied in an embodiment without a blocker, i.e. wherein the magnet itself forms the blocker.
The blocker may be placed in a holder provided on one side of the movable object so that it can be moved by the locking mechanism that will be discussed hereunder. In a preferred embodiment the blocker can move at least in a linear direction. This may allow the blocker to move between at least two states, in particular a retracted state, wherein the blocker moves in the central direction of the movable object, i.e. away from the frame, and an extended state, wherein the blocker moves in the lateral direction of the movable object, i.e. toward the frame. A person skilled in the art will appreciate that the distance between the retracted and extended state may be adjusted to the strength of the magnetic attraction and the height adjustment of the movement mechanism relative to the movable object.
The frame or a guide of the frame is provided with at least one stop element, which is configured for fixing the blocker in an extended state. This stop element may be made of a magnetic material or may comprise a magnetically attractable material, i.e. a material that is suitable for being attracted by the magnet. In one embodiment, the stop element may be made of a ferromagnetic material, such as iron, nickel and cobalt. In another embodiment the stop element may be made of a magnetic or magnetized material with an opposite polarity.
In one embodiment, the stop element may comprise a recess, such as a notch or slot, which is configured to at least receive and fix the blocker. The blocker may comprise a broadened head part that is provided at one end of the blocker, which fits at least partially and preferably completely in this recess. It is advantageous if the diameter of the recess roughly corresponds to the diameter of the blocker and preferably the head part of the blocker so that undesirable displacement can be prevented.
The stop element may be incorporated in the frame or a guide of the frame on the side that corresponds to the side of the movable object in which the blocker is provided. As a result, magnetic attraction may arise between the magnet provided in the movable object and the stop element provided in the frame, or vice versa. This attraction may cause the blocker to slide out so that this goes into the recess described above so that the movable object can be fixed, preferably by means of the movement mechanism, as will be discussed hereunder. A person skilled in the art will appreciate that the rest of the frame, i.e. which does not form part of the stop element, may preferably be made of nonmagnetic materials, such as polymers, to avoid unwanted magnetic attraction. Referring to
In one embodiment, an opening may be provided in the stop element 200 for the placement of a mounting element 220 so that the stop element 200 can be mounted to one side of the frame. The mounting element may be for example a bolt or nut that is screwed into an opening in the frame, or a plate that is secured to a wall of the frame. This may allow the position of the stop element to be adjusted easily, when mounting the locking system, to the user's requirements or the configuration of the door or window supporting system. A person skilled in the art will understand that the stop element may also be secured to the frame in other ways or alternatively may be integrated therein.
As discussed above, the blocker can move between two states depending on the state of the locking mechanism. In the retracted state, the blocker will move past the stop element so that the movable object can move unhindered in the frame, and in an extended state the blocker will block the movement of the movement mechanism so that the movable object is fixed in the frame.
In one embodiment, a plurality of stop elements may be incorporated at various positions in the length of the frame. This may allow the movable object to be fixed at various positions, preferably determined by the user. Because the magnet is magnetically attracted automatically when it moves over a stop element, it is not necessary for a user to look for the position of the stop element, he only has to slide the movable object over the position of the desired stop element. This provides a system that is easy to use and that allows flexible locking of the movable object at several positions in the frame.
As described above, the movable object comprises a movement mechanism that is configured to bring about movement of the movable object in the frame. The movement mechanism may as an example comprise a sliding and/or tilting means in order to put into operation a displacement and/or tilting of the movable object relative to the frame. A person skilled in the art will appreciate that the locking mechanism described herein is not limited to particular movement means, directions and/or drives thereof.
In one embodiment, the movable object is provided with a sliding means to put into operation displacement of the object over the frame. The sliding means may for example comprise a plurality of wheels, rollers or bearings. The wheels may as an example be solid, as is typically provided for indoor applications, or hollow, as is typically provided for outdoor applications. The sliding means may be incorporated in the frame, preferably in a concealed passage provided in the upper and/or lower guide so that it can be completely hidden. A person skilled in the art will understand that when the sliding means and the at least one stop element are incorporated in the same sliding guide, these should not block each other unless this is desired.
In one embodiment, the blocker may be arranged movably in the movement mechanism so that in the lateral direction it can slide into a recess of the stop element. By connecting the blocker directly to the movement mechanism, the moving object can be fixed more efficiently because the displacement of the movement means can be blocked directly. Optionally, the displacement of the blocker may block further movement of the movement means, for example by preventing rotation of the wheels or rollers.
Referring to
In a further embodiment, the locking system may comprise a holder that is configured to retain and optionally shield the blocker. The holder may be placed between the movement mechanism and the tensioning mechanism so that it cannot move. It is advantageous if the holder is clamped between on the one hand an end of the movement mechanism and on the other hand an end of the tensioning mechanism. Such an assembly may allow the height of the movement mechanism to be adjusted, as will be described in more detail hereunder.
Referring to
The holder 400 may also comprise a stop 420, preferably positioned on the opposite side of the blocker, which can be slid into an insertion slot 321 of a tensioning mechanism 320 described below, for mounting the holder 400. As shown, this stop 120 may form a flange. Sliding the holder 400 in may limit the movement of the blocker to one axis, so that the holder cannot move sideways.
As shown in
The locking mechanism comprises a device that is configured to alter the position of the blocker in the movable object between the retracted and extended states discussed above. The locking mechanism thus enables the user to choose whether the movable object is to be fixed or can move freely in the frame. Depending on the configuration, the locking mechanism may also enable the user to choose the position in which the movable object is fixed in the frame.
In a preferred embodiment, the locking mechanism comprises a tensioning cable, which is connected at one end to the blocker and is arranged in such a way that the movement of the blocker is limited in the preferably lateral direction; a tensioning mechanism that clamps the blocker in the extended state and therefore brings the tensioning cable under tension; and a moving component that acts upon the tensioning cable and therefore moves and preferably pulls the blocker to a retracted state.
The tensioning cable may have a length that corresponds to the desired position of the blocker in the extended state. The tensioning cable can be secured to a stationary component of the movable object, such as a profile wall or projection provided in the profile wall, or may be secured to a movable component that forms part of the locking mechanism.
In a preferred embodiment, the tensioning cable is connected on either side to two, preferably opposite, blockers. In particular, the tensioning cable may be connected at one end to a first, preferably upper, blocker and at the other end may be connected to a second, preferably lower, blocker. This may allow the position of these two blockers to be adjusted simultaneously with a single locking mechanism. This forms an especially efficient embodiment of a double-sided locking system without increasing its complexity. This may also ensure that the blockers are at an equal distance from the center of the movable object. This makes mounting of the locking system easier, because the position of each blocker does not have to be set separately.
The tension on the cable can be brought about by providing a tensioning mechanism that acts upon the blocker, and preferably pushes and/or pulls the blocker in the lateral direction. The tensioning mechanism is preferably mounted on one side of the movable object, between the movable object and the frame. In a preferred embodiment, the tensioning mechanism is mounted on an upper and/or lower wall of the movable object or the frame of the movable object. An opening may for example be provided in the tensioning mechanism for the placement of a mounting element such as a screw or bolt. In order to bring about tension, the tensioning mechanism may comprise a spring system, which is made of an elastic and/or springy material so that it is able to return to its original shape when it is bent, stretched or compressed. An example of a suitable spring system is a clamping spring.
In a preferred embodiment, the tensioning means may comprise a spring such as a clamping spring that is placed between a wall of the movable object and the blocker so that it pushes this blocker, and/or a connecting piece that is linked to this blocker, in the lateral direction, i.e. toward the frame. This forms an especially reliable embodiment for achieving locking with less likelihood of wear because friction between movable components is limited.
The resilience of the spring system may be adapted to the intensity of the load, for example depending on the length of the tensioning cable and the weight of the blocker. Depending on the choice of material, the spring system may be more stiff or rigid, or may be more flexible and elastic. A person skilled in the art is assumed to understand how the choice of material may affect the resilience of the spring system.
In one embodiment, the tensioning mechanism may comprise an adjuster that is configured to adjust the distance between the tensioning mechanism and the movement mechanism by controlling the maximum tension range of the tensioning mechanism. Because the tensioning mechanism is mounted to one side of the movable object, the height of the movement mechanism in the frame can be adjusted.
The adjuster may be adjustable for length and/or position, so that it can act upon the spring system described above and/or the connecting piece that is linked to the spring system. As an example, the adjuster may be a rotatable element, such as a bolt, that is configured to push on the spring system and/or connecting piece when turned. This provides an adjustable tensioning mechanism, which may reduce the complexity of the locking mechanism.

The locking mechanism may comprise a handle that is linked to a pivoting body. The handle may be configured to rotate the pivoting body when activated, for example by turning or pushing in. A person skilled in the art will appreciate that other rotating mechanisms exist, and the handle only represents an illustrative embodiment that is simple to use and limits the complexity of the locking mechanism. The pivoting body may be arranged so that on rotation it acts upon the tensioning cable, for example by bending the tensioning cable. The pivoting body may for example be provided with a projecting component, such as an edge or gripper, which grips the tensioning cable and therefore pulls and/or holds the blocker in a retracted state.
In one embodiment, the handle may comprise a blocking mechanism that is configured to block the operation of the handle. The blocking mechanism may for example be a hook or lock that secures this handle in a certain state. As a result, the movable object can be secured to the frame more sturdily.
In one embodiment, the pivoting body is provided with an opening through which the tensioning cable runs. This will ensure that on rotation, the tensioning cable partly bends so that it is displaced to or from the pivoting body, i.e. is pulled or pushed partially sideways. It is to be understood that when the pivoting body acts upon the tensioning cable this is bent in a sideways direction. As a result, the length of the tensioning cable between the pivoting body and the blocker will be shortened, so that the blocker is pulled toward the pivoting body, i.e. to the retracted state. It is clear that such a locking mechanism can also interact with a tensioning cable which at one end is connected to the blocker 100 and at its other end is secured to the movable object 10. It is clear that such a locking mechanism may also interact with a tensioning cable that at one end is connected to a blocker 100 that is connected at one end of the movable object and at its other end is secured to a blocker 100 at an opposite end of the movable object 10. It is clear that embodiments of such mechanisms without a tensioning mechanism for tensioning the tensioning cable are possible. According to such embodiments, the blocker 100 may be held in the retracted state through action of the locking mechanism on the cable, and/or for example by gravity when the blocker 100 is not attracted by the stop element 200.
In a preferred embodiment, the locking mechanism may be incorporated in the movable object completely. The movable object may be provided with a hollow framework that provides a space for placement and mounting of the locking mechanism.
