Description

Floor-lifting and / or ceiling-lowering sealing device Technical field

The present invention relates to a floor-lifting and / or ceiling lowering device for a sliding element, such as a sliding door. Description of the Prior Art

Sliding elements or sliding doors are well known. Brush seals are a well-known and often workable solution, especially for sliding doors. However, they produce a relatively high friction and are also subject to heavy wear. In addition, the sealing effect is limited by the structure of the brush and maximum friction. One of the preferred solutions for sealing sliding doors is in a lowering seal which is lowered from the door leaf of the sliding door down to the threshold. This embodiment has the advantage that the force of gravity is a gap between a lowerable sealing strip and a groove in which the sealing strip is pulled upwards, automatically protected from dust and other troublesome small parts that fall out in the event of intrusion down and can be swept away ,

However, there are cases where the above solutions are technically unworkable, such as frameless sliding glass doors or sliding doors with minimized visible suspensions.

It is therefore desirable to develop a seal which allows a sliding element to be securely sealed without having to accommodate devices in a frame of a door leaf or sliding door so that, for example, a frame of the door leaf or sliding door minimizes and, possibly, completely can be omitted.

It is also desirable not to use floor-protruding elements which are tripping hazards for a person passing through a sliding door can. Furthermore, it is desirable to have a floor-lifting gasket available which ensures accessibility to wheelchairs and walking aids.

Brief description of the invention

The present invention provides a floor lift seal device or a sink seal device for a sliding element, a door, more preferably a sliding door. A sliding element is inserted into a frame which comprises an upper and a lower frame element as well as two lateral frame elements. In the case of a sliding door correspond to the lower frame member of a threshold strip and the upper frame member a lintel, and the side frame members the lateral parts of a door frame. The floor or threshold lifting / ceiling lowering / sealing device / fall-lowering sealing device comprises a lower frame member or an upper frame member in which a sealing strip is movably arranged. The lifting or lowering seal further comprises an operating element, which is arranged next to a sliding element and thus not in or on the sliding element itself. The lifting or lowering seal is set up to extend the sealing strip upon actuation of the operating element from the lower frame member or from the upper frame member up or down or the sealing strip upon actuation down into the lower frame element threshold strip or up in retract the upper frame element. The control element is not attached to the sliding element itself or a sliding element of the sliding element but next to an immovable (independent of a movement of the sliding door) element such as the wall or the Schiebelementzarge attached. Thereby, all elements and components of the stroke sealing device can be installed in fixed parts of a building or a vehicle. As a result, it is likewise possible to dispense with mounting a frame or a handle or the usual operating elements on a sliding element leaf of the sliding element, which has represented a considerable limitation in particular for glass sliding element designers in the design and design of glass sliding elements in particular for decades. In addition, the weight of the mechanism, which is housed in the wall, plays a minor role, which allows it to increase its stability and save costs.

In one embodiment of the present invention, there is provided a floor lift seal device or a sink seal device for a door, more preferably a sliding door. The floor or threshold lift / fall / sink sealing device comprises a threshold strip or a fall, in which a Sealing strip is movably arranged. The lifting or lowering seal further comprises an operating element which is arranged next to a sliding door and thus not in or on the door leaf of a sliding door. The lifting or lowering seal is set to extend the sealing strip upon actuation of the control element from the sill strip or from the fall up or down or retract the sealing strip upon actuation down into the sill strip or up into the fall. The operating element is not attached to a door leaf of the sliding door but next to an immovable (independent of a movement of the sliding door) element, such as the wall or the door frame mounted. Thereby, all elements and components of the stroke sealing device can be installed in fixed parts of a building or a vehicle. As a result, it is also possible to dispense with mounting a frame, a handle or the usual operating elements on a door leaf of the sliding door, which for decades has represented a considerable limitation, in particular for glass sliding door designers, in the design and construction of, in particular, sliding glass doors. In addition, the weight of the mechanism, which is housed in the wall, plays a minor role, which allows it to increase its stability and save costs.

Hereinafter, for the sake of clarity, the term "stroke seal" will be simply used instead of the terms "bottom lift seal device or a ceiling lintel seal device". In this case, the sealing strip may be provided with a seal, in the case of a bottom-lifting seal, however, it is provided to attach a seal on an underside of the door panel, wherein the sealing strip is pressed from below against the seal. In this embodiment, the sunken in a bottom sealing strip can be made stable enough so that it is aligned in a lowered state with the bottom or a bottom bar and does not yield under load. In this design, the sealing strip can be level and smooth with the bottom, so that not even a walking stick with a tip in the Dichtleistennut can catch.

In the following, instead of the more general term sliding element, the more specific term sliding door is used, since this nomenclature allows the individual elements of the system to be described more simply and clearly. The frame in which the sliding element can be displaced comprises an upper and a lower frame element as well as two lateral frame elements. In addition, these frame members are referred to in accordance with the usual names for doors, the lower frame member is referred to below as the threshold strip and the upper frame member as a lintel, without thereby making a restriction only to doors. The side frame members the lateral parts of a door frame. The leaf of a sliding element becomes also referred to hereinafter as the door leaf. The term sliding element is intended to include sliding doors, folding sliding doors, and curved sliding doors, sliding windows and sliding walls. The present invention can be used in particular with frameless sliding elements or sliding elements with a minimized frame, since a mechanism for sealing the sliding element is integrated in a frame element.

In one embodiment of the present invention, the operating element is arranged in or on a frame of the sliding door. By installing in a frame or a sliding door frame / door frame, the mechanism for operating the sealing strip can be easily installed, e.g. during installation of the sliding door. The dimensions of the frame are known in the design of the sliding door, and the frame can be designed with little effort to accommodate the control and the linkage.

In a further embodiment of the floor-lifting gasket for a sliding door, the operating element is arranged on a wall. The operating element can preferably be arranged on a wall next to the sliding door. For example, in an electrical connection, a coupling between the control element and an electric actuator for moving the sealing strip on the other hand, no restrictions due to dimensional accuracy and the like. This embodiment also has the advantage that the place where the control element is mounted, not on the Door frame is limited, but the control can be placed anywhere in a room, which may be useful especially for sliding doors with, for example, electrical Öffhungs- and locking device, for example, on a door or next to a couch. In one embodiment of the floor-lifting gasket for a sliding door, the control element is mechanically coupled via a linkage with the sealing strip. Linkages have long been used in the field of window closures to lock a window or change a stop of a window. In a preferred embodiment, the linkage of the floor lift seal for a sliding door is designed as a push and pull linkage. In this case, for example, can be transmitted via a lever, a movement from a position at a handle height to a movement of the sealing strip at a threshold. It is also possible to use a rotary linkage in which a rotational movement of a rod is used to transmit a movement from the operating element to a height of the threshold. However, it is also possible to use a rotary linkage to move the sealing strip up or down. It also seems useful to point out that a push or pull rod can be used to raise the sealing strip on the sill strip or lower into this. In a further embodiment of the floor-lifting gasket for a sliding door, the control element is hydraulically coupled to the sealing strip. A hydraulic coupling can avoid many problems that can occur when laying a coupling line. The corresponding controls and actuators can be performed seal-free in a closed system, which leaks and leaks can be avoided.

In another further embodiment of the floor-lifting gasket for a sliding door, the control element is pneumatically coupled to the sealing strip. A pneumatic coupling makes it possible to use an elastic, hollow sealing strip which can easily be brought to rest on the sliding door by inflating. It is advantageous that it is possible to dispense entirely with a gap, since the sealing strip does not have to move into or out of a groove. In this embodiment can be completely dispensed with a downwardly open groove. This can significantly reduce a need for continuous maintenance, since no dirt can penetrate into a gap between a movable sealing strip and a groove.

A further embodiment of the floor-lifting gasket for a sliding door further comprises at least one electrically operated actuator. The control element is designed here as an electrical switch or electrical control and is electrically coupled to the actuator. The bottom lift seal is set up to energize the actuator upon actuation of the control element and the actuator is configured to extend the weather strip upward upon actuation of the control element from the threshold rail or to retract the weather strip into the threshold rail upon actuation. An electrical drive simplifies the connection between the actuator and the operating element, but requires a power supply. This embodiment can be very easily combined with an opening, ventilation or climate control. In a further embodiment, the control element of the floor-lifting gasket for a sliding door is wirelessly coupled to at least the sealing strip. Although two power supplies are required here on the one hand for the actuator of the sealing strip and on the other hand for the operating element, this embodiment can be combined or implemented, for example, with a smartphone via Bluetooth or W-LAN or an NFC communication, dispensing with a separate operating element can. The control element can be implemented here, for example, as a program or an app. Here, a smartphone can be used to control sliding doors. Here and in the Throughout the document, the term "sliding door" is preferably to be understood as a "sliding glass door", especially a sliding glass door with minimized view width of the frame profiles.

In a further additional embodiment of the floor lifting gasket for a sliding door, it further comprises a locking device with which a sliding door can be locked, wherein components of the locking device are arranged in the sill strip and the sliding door, and wherein the locking device of the control element for the lifting gasket can be controlled from. In a preferred embodiment of the floor lifting gasket for a sliding door, the locking device can lock the sliding door in an open position in a closed position and in at least one intermediate position. As a result, the sliding door can also be opened and locked in any intermediate position, for example one finger width or one hand width. Preferably, the lock can be controlled without the lifting seal must be raised. It is intended to control by the control element first the lock and then the stroke seal. In preferred embodiments, the lifting seal can only be raised in a fully closed or pushed position. By this measure, it can be prevented that a user steps on an extended stroke seal and this or a lifting device damaged.

In a further embodiment of the floor-lifting and / or ceiling lowering device for a sliding element, a control element is provided which provides at least one position, locked in the locking device, the sliding element in the closed position, and in which the sealing strip is not or not completely is raised. In this embodiment, a so-called safe night ventilation is possible without the sliding element, e.g. could be opened from the outside. In an additional embodiment, the operating element may comprise a part which controls only one opening of the sealing strip with the sliding element closed and locked. It may even be provided to use a system of two lower or upper strips, wherein in addition to a conventional sealing strip also still a grid sealing strip is present. The grating sealing strip may have openings to allow gas exchange, but small animals denied access to a closed mesh sealing strip similar mosquito net. The normal tightness can be maintained by the control element or by a part of the control element in an open, at least half-open intermediate position or in a completely closed insulating position.

It may also be provided that a grid sealing strip, as described above, always brought into a raised or closed position, and only an additional part of the operating element, an opening degree of the non-perforated sealing strip can be adjusted in the closed and locked sliding element. Here, both sealing strips, the grating sealing strip and the normal sealing strip can be moved together by a common part of the operating element, and only one position allows a part of the operating element to allow it with closed sliding element and closed or raised grille sealing strip, by lowering the sealing strip a night ventilation , This principle can be applied to both a lower and an upper frame member. It can be provided to use a corresponding combination of sieve and seal both on the lower frame member and on the upper frame member.

It is also envisaged to be able to control the sealing strips separately above and below in order to allow different forms of night ventilation. It is also possible to use lattice sealing strips on both upper frame members and lower frame members. Like a mosquito net, lattice sealing strips are designed to prevent insects such as mosquitoes from entering a dwelling or house through a gap between an open sealing strip and a sliding element during active night ventilation.

Another embodiment of the floor-lifting gasket for a sliding door further includes an opening and closing device, with which the sliding door can be opened and closed, and which can be controlled by the operating element. The present invention uses a control element that is not attached to the door or the door leaf, but on the frame or the wall next to it. This means that the person operating the lift seal will grip the side of the door and may not have his hand free to open or close the door. Therefore, an opening and closing mechanism or an opening and closing device may also be provided on the door so as to be able to effect a locking and an opening or closing of the door when operating the lifting seal.

In one embodiment of the floor lifting gasket for a sliding door, the control element comprises a lever, a linkage, a pivoting lever and a sealing strip. The floor lift seal can be moved to an open position by moving the lever and linkage over the pivoting levers from a sealing position where the sealing strip contacts the bottom of a sliding door with the sealing strip recessed into the threshold rail. Of course, a reverse operation is possible in the the sealing strip can be sunk in the threshold strip. The linkage can also be designed as a rotary linkage. It should be noted that here also only parts of the linkage or the entire linkage can be designed as a push, pull and / or rotary linkage and that in all the embodiments mentioned here.

In accordance with another aspect of the present invention, a lift and / or ceiling lowering device for a sliding door is provided. Again, one or two sealing strips in a threshold strip and / or a lintel is movably arranged again. According to the present aspect of the present invention, the operating element is arranged on a door leaf of the sliding door, as on the movable part itself. The floor-lifting and / or ceiling-lowering sealing device is set up to extend the respective sealing strip upon actuation of the operating element from the threshold strip upwards and / or out of the lintel or the sealing strip on actuation of the operating element down into the threshold strip and / or to drive up into the lintel. The operating element preferably comprises at least one push rod that runs perpendicular to the sill strip and / or the lintel. When retracted sealing strips, the push rod is retracted into the door, and one end of the push rod has a distance from the sill strip and / or the lintel on. When actuated to extend a respective sealing strip, the push rod bridges a gap between a door leaf and the sill strip and / or the lintel by a pushing movement until a pressure or a pushing movement of the push rod on a mechanism in the sleeper and / or the lintel causes the Extend sealing strips.

According to another embodiment of the invention, there is provided a floor-lift and / or ceiling-lowering device for a sliding door comprising a sill strip and / or a lintel in which a sealing strip is movably arranged; and a wedge member and / or a lever disposed in the sill and / or the lintel, wherein a door leaf of the sliding door includes an actuator to cooperate with the wedge member and / or the lever, wherein the bottom lifting and / Ceiling-lowering seal is set to extend the respective sealing strip at a closing of the sliding door by an interaction of the wedge element and / or the lever with the actuator from the threshold bar up and / or out of the lintel down and wherein the sealing strip is set up at to open an opening of the sliding door by an interaction of the wedge element and / or the lever with the actuator down into the sill strip and / or up into the lintel. In an additional exemplary embodiment of the floor-lifting and / or ceiling lowering sealing device, the sealing strip and the sliding element, and / or the lower frame member and / or the upper frame member is provided with magnets. In an arrangement of the magnets in the upper or lower frame member, the magnets may be connected to parts of the operating / actuating device to press the sealing strip against the sliding element when the sliding element is closed. It is also envisaged to use magnetic forces of the magnets to move the sealing strips. In one embodiment, the magnets in the sealing strip serve to form a magnetic spring, by means of which the sealing strip is pressed against a sealing surface. In this case, magnetic repulsion forces are preferably used, so that it is very easy to separate the seal again from the sealing surface. A combination of repulsive forces and a moving magnet allows easy and quick lifting and lowering.

Brief description of the drawings

In the following, the present invention is illustrated by means of schematic figures of exemplary embodiments.

FIGS. 1A to 1C show a transverse partial section through various embodiments of a lifting seal according to the invention.

FIG. 2 shows a transverse partial section through another embodiment of a lifting seal according to the invention. Figures 3A and 3B show schematic drawings of a sliding door with another embodiment of a lifting seal according to the invention and with a lowering seal.

Figures 4A and 4B show schematic drawings of a sliding door with another embodiment of a lifting seal according to the invention and with a lowering seal.

Both in the figures and in the description, the same or similar reference numerals are used to refer to the same or similar elements or components. Description of the embodiments

FIG. 1A shows a transverse partial section through an embodiment according to the invention Hubdichtung. The partial cross-section extends through the sill strip 10 of the sliding door 4. The sliding door 4 is preferably supported in this embodiment by a support roller 16 which runs in a roller groove in the sill strip 10. Alternative support arrangements are also possible. It can be provided, which also lead the door 4 perpendicular to a profile of the door leaf or the threshold strip 10 more roles. In the baseboard also a rotary linkage 12 is arranged. On the rotary linkage 12, an arm (for example in the form of an Allen screw) is arranged, which extends up to a Dichtleistennut 8. The arm is engaged with a recess on a sealing strip 8 in engagement. Upon rotation of the linkage designed as a linkage 12, the sealing strip 6 is extended from the Dichtleistennut 8 in the sill strip 10 upwards. On the sliding door 4, an elastic sealing element is attached below, against which the sealing strip 6 rests in an extended position and thus seals a lower gap between the sliding door 4 and the sill strip 10. The solid lines show the linkage 12 and the sealing strip 6 in a retracted position. The dashed lines show the linkage 12 and the sealing strip 6 in a deployed from the sill strip 10 position.

The linkage 12 and the sealing strip are operated by a control element, not shown in FIG. 1A, which is arranged on a wall or a façade but not on the sliding door 4 or the sliding door leaf. Thus, the entire mechanism for a sealing strip can be removed from the door leaf, and the sliding door is subject to much less design restrictions, since the required in the prior art linkage in a design need not be considered. With the present invention, a sliding door designer has more design and design options than conventional lift and sink seals integrated into the sliding door panel.

FIG. 1B shows a transverse partial section through a further embodiment of a lifting seal according to the invention. The lifting seal of Figure 1B differs from that of Figure 1A in that the seal is disposed on the sealing strip and not on the underside of the sliding door or the sliding element. As a result of this change, the material of the seal can seal the gap in which the sealing strip moves up and down and prevent dust from entering the gap with the door open and the sealing strip retracted. The other aspects of the sealing strip and the operation correspond to those of Figure 1 A.

Figure IC shows a transverse partial section through a further embodiment of a lifting seal, in which a magnetic spring is used to the sealing strip against a Sealing surface of the door to press. The sealing strip rests on a stop and can not move further down when the door is open, even under load. The seal on the sealing strip can seal the gap in which the sealing strip is located. The sealing strip is provided with magnets that have a north pole at the bottom and a south pole at the top. In a rest position with the door open, the strip is in the groove and can be loaded from above. Below the actual sealing strip a control strip or magnetic spring strip is arranged, which is also provided with magnets. The magnetic field direction of the magnet of the control bar is arranged so that they repel the magnets in the sealing strip. The magnetic fields are stronger at a small distance than at a large distance. In a rest position, the control bar is lowered and the greater distance of the magnets results in a magnetic force that is insufficient to lift the sealing strip against gravity out of the gap. When the control bar is raised, the distance between the magnets decreases and the magnetic force presses the sealing strip out of the groove against a sealing surface of the closed sliding door.

The magnetic force of the bar or bar magnet and in particular the repulsive force is strongly correlated with the distance of the repelling magnet. In the case of bar magnets, the repulsive force correlates with the inverse of the square of the pitch of the poles. Here this means that the corresponding magnets can be chosen so that at the larger distance Dl between the magnet of the control bar and the sealing strip, the magnetic force is significantly below the force acting on the sealing strip gravity. With appropriate design and for low values of D2, the smaller distance between the magnet of the control bar and the sealing strip, a magnetic force can be achieved, which ensures a sufficient seal between the door or the sliding element and the sealing strip. There is the advantage that the lower edge of the door can not be made magnetic, which can prevent that under the door magnetic elements, such as nails or paper clips, collect. Another advantage of the embodiment of Figure IC is that the sealing strip can be easily removed to clean the Dichtleistennut. This can significantly simplify the maintenance of the system, since the sealing strip can be easily taken out to the top to clean the groove, for example. With a vacuum cleaner.

Instead of the solution with permanent magnets shown in the figure IC, it is also possible to use electromagnets on the sill or the door lintel side to raise the sealing strip.

FIG. 2 illustrates an integrated solution for a sliding glass door according to FIG. 1, where the stroke seal is integrated into the sill strip. The sill strip houses all the components, and the lower end of the glass door leaf can also be integrated into the sill strip. This design makes it possible to use a glass door, which is perceived from the outside only as a continuous glass surface, and thus can be integrated seamlessly into a glass facade. The reference numerals and elements of this door and the threshold strip are the same as in the case of the lifting seal of Figure 1, which is why there is no redundant repetition. The threshold bar forms particularly preferably with the surrounding soil a uniformly flat surface. Figures 3A and 3B show a schematic drawing of a sliding door with another embodiment of a lifting seal according to the invention and with a lowering seal according to the invention.

FIG. 3A shows the lowered sealing strip 6 of the lifting seal and a retracted sealing strip of a lowering seal 20 and a partially opened sliding door 4. Only the lower or upper part of the sliding door 4 is shown. All guides and rollers as well as handles or locks have been omitted. The sealing strip 6 of the stroke sealing device is mounted with two scissor mechanisms on a base of a sealing strip groove, also not shown. The sealing strip of Senkdichtungsvomchtung is mounted with two scissor mechanisms in a lintel in a sealing strip groove, also not shown The control element 14 is designed as a lever which is connected via a respective draw or pressure linkage with the scissor mechanisms. In an upper position of the lever, the scissor mechanisms are retracted and the lifting sealing strip 6 is in the threshold strip and the lowering sealing strip 20 is retracted into the lintel, so that the sliding door can be opened or closed.

Figure 3B shows the lift-seal and sink-seal devices of Figure 3A with the sliding door closed in an extended and sealed position. In the lower position of the lever of the operating element 14, the scissors mechanisms are extended and the sealing strip 6 rests against the closed sliding door 4 from below and the lowering sealing strip rests against the closed sliding door 4 from above. Due to the friction between the sliding door and the sealing strip, the sliding door can not be opened.

In FIGS. 3A and 3B, the sealing strips can likewise be provided with a lock 18, which engages behind an edge of the sliding door 4 in the case of a closed sliding door 4 and thus secures it against being pushed against the frictional force between the sliding door 4 and the sealing strip 6. In a lowered lifting sealing strip 6 and a Retracted lowering sealing strip, the sliding door on the lowered latch 18 or slip under the retracted lock. This embodiment also has the advantage that the lock 18 prevents the sealing strip 6 can be extended as long as the sliding door 14 is not completely closed. In a partially open sliding door, the lock 18, which is designed here as a locking hook, when extending the respective sealing strip 6 against a bottom or top of the sliding door 4, whereby further extension of the sealing strip is prevented. Thus, the lock can also prevent a extended when open sliding door 4 sealing strip is damaged by a person stepping on it.

An actual seal can be attached to the door itself. It can also be used other lifting and lowering devices, not shown. The sealing strips especially the countersinking sealing strip can be provided with a seal which abuts against an upper surface of the sliding door and ensures a reliable seal. A lower lift-sealing strip is preferably not provided with a seal, but is pressed from below against an underside of the sliding door, which is provided with a seal.

Figures 4A and 4B show a schematic drawing of a sliding door with another embodiment of a lifting and lowering sealing device according to the invention.

FIG. 4A shows the lowered sealing strip 6 of the lifting seal and a retracted sealing strip of a lowering seal 20 and a partially opened sliding door 4. All guides and rollers as well as handles or locks have been omitted. The sealing strip 6 of the stroke sealing device is mounted with two scissor mechanisms on a base of a sealing strip groove, also not shown. The sealing strip of the lowering sealing device is mounted with two scissor mechanisms in a lintel in a sealing strip groove, also not shown. The control element 14 is designed as a lever which is connected in each case via a tension or pressure linkage with the scissor mechanisms. In an upper position of the lever, the scissor mechanisms are retracted and the lifting sealing strip 6 is in the threshold strip and the lowering sealing strip 20 is retracted into the lintel, so that the sliding door can be opened or closed. The sealing strips can be held in a retracted position by gravity or by a spring (not shown). Figure 4B shows the lift seal and sink seal device of Figure 4A with a closed sliding door in an extended and sealing position. In the lower position of the lever of the operating element 14, the scissor mechanisms are extended and the Sealing strip 6 rests against the closed sliding door 4 from below and the lowering sealing strip rests against the closed sliding door 4 from above. Due to the friction between the sliding door and the sealing strip, the sliding door can not be opened. The sealing strips are held in an extended position by the force of the push rods.

In FIGS. 4A and 4B, the sealing strips are likewise provided with a lock 18, which engages behind an edge of the sliding door 4 in the case of a closed sliding door 4 and thus secures them against being pushed against the frictional force between the sliding door 4 and the sealing strip 6. With a lowered lifting sealing strip 6 and a retracted lowering sealing strip, the sliding door can slide over the lowered latch 18 or under the retracted locking. The embodiment of FIGS. 4A and 4B also has the advantage that the push rods in the sliding door can only move the levers in a closed state and bring about a raising or lowering of the sealing strips. The sealing strips can only be extended when the sliding door 14 is completely closed. In a partially open sliding door, the push rods can not move the lever and the sealing strips retract. Thus, it is also effectively prevented in this embodiment that an extended when the sliding door 4 extended sealing strip can be damaged. In the following, it is also pointed out that combinations of elements and components which are illustrated in individual different embodiments are to be regarded as disclosed. It should be understood that the linkage may or may include only portions of the linkage, individual pusher, pull and / or turn bars, alone or in combination, in all of the embodiments herein.
