Description

TECHNICAL AREA

The present invention relates to a lowering sealing device according to the preamble of patent claim 1 and to a triggering unit of such a lowering sealing device.

STATE OF THE ART

Automatically mechanically lowerable sealing devices are known. They are generally used for threshold-free doors to seal the lower gap between the door leaf and floor against draft, sound and light transmission. Proven has a seal, as for example in EP 0 338 974 is disclosed. The actuation of the sealing device takes place automatically when closing and opening the door. Examples of corresponding lowering mechanisms are in EP 0 509 961 . DE 19 516 530 . DE 3 526 720 . DE 3 418 438 and DE 3 427 938 disclosed. The actuation of the lowering seal is carried out on one or two sides, but always frontally by a door leaf protruding spring-loaded release pin is pressed when closing the door.

Furthermore, lowering seals are known, which are triggered by a vertical bar. This vertical bar is connected to the door lock. An example of this is EP 2 063 060 , Here, a wedge-shaped end of a vertical rod acts on a wedge-shaped end of a horizontally extending actuating rod. However, the force required for the reduction is relatively large and multiplies with the length of the seal.

EP 2 305 938 . JP 10 238 250 . JP 9 151 679 . JP 978 958 use pivotal elements to transmit an externally applied force to the actuator of the lowering mechanism. WO 2010/057226 suggests the use of power transmission hubs.

EP 2 085 559 discloses an automatically lowerable window or door seal, which laterally, that is triggered perpendicular to the longitudinal direction of the sealing strip. For this purpose, a bolt, which passes through a window in the housing of the seal, engages in the lowering mechanism.

EP 2 634 350 discloses a seal for sliding doors, which can be triggered on one side of the front side with pressure and which is triggered on the opposite side with train. For this purpose, an end face of the seal at right angles projecting boom is arranged on the tension side. If, when closing the sliding door, this trigger is attached to a stop of a door frame, the seal lowers. This solution requires a relatively large amount of space and the force required to trigger the seal is relatively large.

The power transmission module according to CH 704 410 with the frontal release has been proven, especially since the release force can be reduced. However, this module can not be used depending on the design of the sliding door.

PRESENTATION OF THE INVENTION

It is therefore an object of the invention to provide a Absenkdichtungsvorrichtung and a trip unit for a lowering seal, which requires a relatively small amount of force for the operation of the seal and thus is suitable for use in long sliding gates.

This object is achieved by a lowering sealing device having the features of patent claim 1 and a triggering unit having the features of patent claims 15 and 16, respectively.

• eine Gehäuseschiene,
• eine in der Gehäuseschiene absenkbar und anhebbar gehaltene Dichtleiste,
• einen in der Gehäuseschiene angeordneten Absenkmechanismus zum Absenken der Dichtleiste,
• ein mit dem Absenkmechanismus wirkverbundenes und in der Gehäuseschiene angeordnetes Betätigungselement, welches durch seine Verschiebung in Längsrichtung der Gehäuseschiene den Absenkmechanismus betätigt, und
• ein Schwenkelement, welches eine auf das Schwenkelement einwirkende externe Auslösekraft auf das Betätigungselement übermittelt.

The inventive lowering sealing device for a wing of a sliding gate, a sliding door or a sliding window comprises:

• a housing rail,
• a sealing strip which can be lowered and raised in the housing rail,
• a arranged in the housing rail lowering mechanism for lowering the sealing strip,
• an operatively connected to the lowering mechanism and arranged in the housing rail actuator, which actuates the lowering by its displacement in the longitudinal direction of the housing rail, and
• a pivot member which transmits an acting on the pivot member external release force on the actuating element.

The pivoting element is pivotable about an axis which runs perpendicular to the longitudinal direction of the housing rail. The pivot member has a first arm and a second arm, wherein on the first arm a trigger element is arranged or wherein the first arm with a trigger element is contacted or connectable and wherein the second arm acts on the actuating element of the seal. According to the invention, the triggering element projects in front of the first arm perpendicular to the longitudinal direction of the housing rail.

The inventive sealing device is relatively simple and space-saving design. Their release by lateral force has several other advantages. The power transmission can be easily selected by appropriate configuration of the individual components of the seal. In addition, the lateral force on Schiebetoren- or doors and sliding windows allows other forms of design as the power module according CH 704 410 , Another advantage is that the seal can be arranged anywhere in the door or door leaf. Furthermore, it is advantageous that the trigger element protrudes only laterally, but not in the length of the seal and the door leaf. In addition, the trip unit can be made simpler and thus smaller and less expensive. A great advantage is that the trip unit is a separate component with respect to the rest of the sealing device. This facilitates the assembly.

In the following, we talk about "gates", including "doors" and "windows".

The trip unit is designed with the simplest means and in minimum size, when the second arm acts directly on the actuator. However, it is also possible that the second arm acts on the actuating element via further means. For example, the second arm may be part of a transmission, a cable or a Bowden cable.

Preferably, the actuating element is a bolt which extends in the longitudinal direction of the housing rail and which is connected to a slider of the lowering mechanism, as is known from the abovementioned prior art lowering seals. The trip unit according to the invention can thus be used in particular for this type of seals. Preferably, it is used for a lowering seal, as in CH 704 410 is described. Preferably, the second arm engages in a window of the housing rail of Absenkdichtung.

Preferably, the trigger element pivots the first arm by the action of force parallel to the longitudinal direction, but counter to the closing direction of the wing of the housing profile rail about the pivot axis. This movement allows a high degree of flexibility in the design of sliding gates. In particular, one-piece seals, preferably of up to 10 meters, can be activated with a single trip unit for a very long time. This is particularly advantageous when using the sealing device in long gates. However, it is also possible with this sealing device to actuate a plurality of successively arranged sliding gates through the respective preceding sliding gate.

The triggering element may be fixedly connected to the first arm or it may connect to this arm upon actuation of the device, for example by engaging in a recess of the first arm. In the second case, the triggering element is preferably arranged on the building wall or on the door or window frame, in particular attached thereto. In preferred embodiments, the trigger element is a bolt.

Preferably, a guide is present. In preferred embodiments, the trigger element passes through a window of a housing of the trip unit, wherein the trigger element is movable within this window. The window can thus serve as a double-sided stop.

So that the seal can be lowered with the least possible effort, the first arm is made longer than the second arm. Preferably, the first arm is designed to be many times longer than the second arm. If a reduction is desired, this can be achieved by making the first arm shorter than the second arm.

A simple and space-saving embodiment is in those embodiments, in which the two arms of the pivot member are fixed and fixed in position with each other and / or the pivot member is integrally formed. The two arms form a common lever, the arms being defined by the pivot axis.

In order that the lowering seal is optimally activated, in preferred embodiments the second arm has a force transmission surface for contacting the actuating element. This force transmission surface is preferably formed evolvent-shaped.

The trip unit can be easily mounted when the pivot element or the lever is arranged in a housing. Preferably, the housing has a front plate or a cuff plate for attachment to an end face of the wing. The housing also allows the simple formation of a window in one of its side walls. The triggering element preferably protrudes outwards from the housing or projects into the housing from the outside.

In one embodiment, the release unit of the lowering sealing devices according to the invention has a pivot element or a lever which is designed to transmit an external release force acting on the pivot element to an actuating element of a lowering seal of the lowering sealing device. The pivoting element is pivotable about a pivot axis. It has a first arm and a second arm, wherein a trigger element is arranged on the first arm or wherein the first arm is contactable or connectable with a trigger element and wherein the second arm acts on the actuating element. According to the invention, the triggering element projects in front of the first arm parallel to the pivot axis.

In the same or a further embodiment, the triggering unit according to the invention of the lowering sealing devices described above has a pivoting element which is designed to transmit an external triggering force acting on the pivoting element to an actuating element of a lowering seal of the lowering sealing device. The pivoting element is pivotable about a pivot axis. The pivoting element has a first arm and a second arm, wherein the first arm, a triggering element is arranged or wherein the first arm with the triggering element is contactable or connectable.

DESCRIPTION OF PREFERRED EMBODIMENTS

In the Figures 1 and 2 is a sliding gate or a sliding door shown. A Schiebetorflügel is denoted by the reference T, the adjacent walls or door frames with W1 and W2 and the bottom with B. The closing direction of the door leaf is in FIG. 1 shown with an arrow.

In the illustration according to FIG. 2 is the Absenkdichtungsvorrichtung invention recognizable. It has a lowering seal 1 and a release unit 2. The lowering seal 1 is an automatically mechanically releasable lowering seal known type, as disclosed for example in the patent publications described above. It has a housing rail 10 (see FIG. 7 ), which is firmly connected to the door leaf T. It can, for example, at the lower end of the door or in a be arranged lower groove of the gate. The lowering seal 1 is firmly connected to the door leaf T.

The lowering seal 1 further comprises a relative to the housing rail 1 can be raised and lowered sealing strip. The sealing strip preferably has a carrier rail 12 and a one-piece or multi-part elastomeric sealing profile 11 fastened thereto. Housing rail 1, support rail 12 and sealing profile 11 preferably extend approximately over the entire width of the door leaf T. Depending on the embodiment, the lowering seal can also be made shorter.

The lowering mechanism of the door leaf T is not completely visible in the figures. However, it is preferably designed as already described above, in particular as in DE 195 16 530 and the other patent publications of Planet GDZ AG. The lowering mechanism comprises an actuating element, here an actuating pin 13, which extends in the longitudinal direction L of the housing rail 10 and is connected to a slide 15, which in turn is connected to ends of leaf springs. A part of the slider 15 is in FIG. 10 recognizable. The leaf springs are fastened with a second end to the housing rail 10 and connected in a central region with the support rail 12. As a result, the carrier rail 12 is lowered together with the sealing profile 11 when the actuating bolt 13 is pushed further in the longitudinal direction L into the housing rail 1.

According to the invention, the device has the triggering unit 2 already mentioned. This has a housing 20 (see the FIGS. 3 and 4 ) with a front panel 21, which serves for fastening the trip unit 2 at the rear end side of the wing T in the closing direction of the door leaf T. The mounting holes for corresponding screws are designated by the reference numeral 29.

Preferably, the lowering seal 1 is held by means of the trip unit 2 on or in the door leaf T. For this purpose, the housing 20 preferably has a fastening angle 28, in which an upper web of the housing rail 10 of the lowering seal 1 can be suspended. The attachment of Absenkdichtung 1 on the other side of the door leaf T can be done in a known manner. In particular, it can by means of a Fixing bracket 14 may be screwed to the opposite end face of the wing T. This one is in FIG. 9 shown.

The trip unit 2 has a triggering element, here a trigger pin 22, which protrudes a side wall 23 of the housing 20. He thus runs perpendicular to the longitudinal direction L of the housing rail 10 and the lowering seal 1. When closing the door of this trigger pin 22 slides initially unhindered along the wall of the building and the door frame until it reaches a stop A. This is in the Figures 1 and 2 recognizable. If the gate continues to be closed, the trigger pin 22 is moved in the direction parallel, but opposite to the closing direction, to the rear, and he lowered the sealing strip against the spring force of the Absenkmechanismus from. The sealing strip seals the door leaf T from the ground. The closing movement is in FIG. 1 visible by the arrow. If the gate is opened again, the trigger pin 22 moves away from the stop A and the sealing strip is raised again due to the restoring force of the springs.

Alternatively, the release bolt 22 could also attach to the door frame or on the wall, wherein it engages in the housing 20 of the trip unit 2 and activates the mechanism there.

The mechanism of the trip unit 2 is in FIG. 5 as well as the FIGS. 8 to 11 good to see. It comprises a pivoting element or a lever with a first arm 25 and a second arm 26, which are firmly connected to each other and which are pivotable about a pivot axis 27. The pivot axis 27 extends perpendicular to the longitudinal direction L of the housing rail 1 and parallel to the release bolt 22. The pivoting movement of the first arm 25 when closing the door leaf T is in FIG. 5 shown with an arrow. The second arm 26 is thereby pivoted in the opposite direction.

The first arm 25 is preferably rectilinear. The second arm 26 is preferably arranged at an angle to the first arm 25, wherein it is preferably inclined to the pivot axis 27. However, the first and second arms 25, 26 preferably extend in a common plane perpendicular to the pivot axis 27.

The second arm 26 has a force transmission surface 260, which contacts the end face of the actuating bolt 13 when closing the door leaf T and thus further pushes the actuating bolt 13 into the housing rail 1. This force transmission surface 260 is preferably formed involute in order to optimally slide along the surface of the actuating pin 13 along.

As in the FIGS. 3 and 4 can be seen, the second arm 26 is the housing 20 down before, so that he can act on the lowering of Absenkdichtung 1. This will be explained in more detail below.

As in FIG. 5 can be seen, the first arm 25 is preferably formed longer than the second arm 26. The division into the first and the second arm 25, 26 takes place at the pivot axis 27. Preferably, the first arm 25 is many times longer. As a result, a reduced power transmission is achieved, so that a low release force is sufficient to lower the seal.

The housing 20 has in a side wall 23 a window 24 in the form of a curved slot. Through this window 24 of the release bolt 22 which is fixedly connected to the first arm 25 projects. It is arranged at a right angle to the first arm 25 and protrudes the housing 20, as is well in FIG. 6 is recognizable.

In a preferred embodiment, the housing 20 has a window 24 on both sides. As a result, the release bolt 22 can be inserted either through the right or left window 24. The device can thus be arranged on the spot arbitrarily on the right or the left side of the door leaf. The front panel 21 is easy to screw on the housing 20 accordingly.

The housing 20 may have the same width as the front panel 21. Preferably, however, it is narrower so that it can be embedded in a relatively narrow groove of the door leaf T. As a result, the fire protection properties of the gate are hardly changed. Preferably, the front plate 21 is the housing 20 only on one side, as in FIG. 6 is recognizable.

Based on FIGS. 8 to 10 the effect of the trip unit 2 on the lowering seal 1 is clearly visible.

The housing profile rail 10 has a window 100 in its upper surface. Through this window, the second arm 26 of the pivot member protrudes down to the actuating pin 13. The actuating pin 13 is arranged in the housing rail 10. It preferably does not extend to its adjacent end. As a result, the second arm 26 with its force transmission surface 260, the actuating pin 13 contact the front side. He can thus this when closing the door leaf T, when the trigger pin 22 pivots the pivot member and pushes the second arm 26 in the drawing direction to the right, continue to press into the housing rail 10 and thus lower the sealing strip.

In an alternative embodiment, an upwardly projecting carrier is attached to the actuating pin 13, which contacts the force transmission surface 260 of the second arm 26 and upon movement of the second arm 26 transmits the force to the bolt 13. In this embodiment, it is not necessary for the second arm 26 to project down the housing 20, as the driver may also protrude into the housing 20, depending on the design.

The device according to the invention makes it possible to trigger the lowering seals of sliding doors or doors with little effort, wherein the device can be designed with any force transmission or reduction as well as relatively small and simple.
