Abstract

A sealing device of a sliding door with a displaceably mounted door leaf has a lowering seal with a sealing strip (11, 12) and with an actuating mechanism for automatically lowering and raising the sealing strip (11, 12). The sealing device has an activating unit (2, 3, 4) for activating the lowering seal, wherein the activating unit has a first contact surface (21, 22), a pivotably designed contact element (3) and a pivotably designed force transmission element (4). Upon closing of the door leaf, the contact element (3) contacts the first contact surface (21, 22) and moves, during the closing movement of the door leaf, with pivoting of the contact element (3), along the first contact surface (21, 22). A pivoting movement of the contact element (3) results in a pivoting movement of the force transmission element (4), with the result that the latter actuates the lowering seal.

Description

TITLE

SEALING DEVICE FOR A SLIDING DOOR

TECHNICAL FIELD The present invention relates to a sealing device for a sliding door.

STATE OF THE ART

Lowering gaskets are used to seal doors and windows. They prevent the passage of light and provide sound insulation and protection against drafts and smoke. For exterior doors, they also serve as splash protection in the rain and can also protect against flooding, depending on the embodiment.

Usually lowerable door and window seals consist essentially of a housing in the form of a downwardly open, hat-shaped or U-shaped rail, a raised and lowered in this housing sealing strip with a sealing profile and an actuating mechanism for raising and lowering the sealing strip. In proven Absenkdichtungen the actuating mechanism on leaf springs, which are attached to a first location on the housing, at a second location on the sealing strip and at a third location on a slider. The slider is usually in an operating knob, which projects the housing one or both sides. When closing the door, the operating knob is pressed against the door frame and the sealing strip is lowered automatically against the spring force of the leaf springs and pressed sealingly against the ground. When opening the door, the operating button is released again and the sealing strip is raised automatically. There are other types of actuating mechanisms known, such as lever arrangements. Such door seals are known, for example, from EP 0 338 974, DE 299 16 090 and EP 0 509 961. EP 2 085 559 discloses an automatically lowerable sealing device in which the actuating mechanism is activated by lateral force. EP 2 476 857 discloses a lowering seal for sliding doors. The lowering seal is designed as described above and has an actuating button projecting the sealing housing. In the area of the auxiliary closing edge, the door frame has a stop element with a downwardly inclined inclined surface and a rectilinear receiving pocket. When closing the door leaf runs on the door mounted first role of this inclined surface along and pulls a spring-loaded slide down. A roller arranged on the second roller presses a lever on the actuating button, which thereby activates the actuating mechanism and lowers the sealing strip. Upon further closure of the door, the first roller enters the receiving pocket and the lowering movement is stopped. The door leaf is completely closed in this state. The Absenkdichtung remains thanks to the receiving pocket in the closed position, without further blocking devices would be necessary. Only when you open the door, the role is again led out of the receiving pocket, which allows automatic lifting of the sealing strip. This arrangement has the disadvantage that when closing the door, a relatively large effort by the user is necessary because the carriage must be lowered against the spring force and the resistance of the lever pressing on the operating button. Another disadvantage is that when you open the door, the automatic lifting of the carriage causes the door to open automatically and thus the user does not retain full control at the opening. Another disadvantage is that the carriage is arranged in the running direction of the sliding door behind the lowering seal, so that the sealing strip must be formed shortened and can not completely seal in the vicinity of the auxiliary closing edge. Femer allows the end position little play, so that an accurate guidance of the door leaf and accurate positioning of all elements are mandatory.

Lowering seals with an activatable frontal activation button have proven in practice for hinged door. The power transmission ratio when closing the door leaf is without further mechanisms already at about 1: 30, so that the operating knob when closing the door leaf can be pressed without noticeable effort. The use of such lowering seals for sliding doors is more problematic because the power transmission to the operating knob is only 1: 1 and Thus, more force must be expended to depress when closing the door even the operating button.

PRESENTATION OF THE INVENTION

It is therefore an object of the invention to provide an improved sliding door sealing device. This object is achieved by a sealing device having the features of patent claim 1 and each of the sealing devices having the features of patent claims 16, 17 and 18.

The sealing device of a sliding door with a slidingly mounted door has a lowering seal with a sealing strip and with an actuating mechanism for automatically lowering and raising the sealing strip. The lowering takes place counter to a restoring force. The sealing device has an activation unit for activating the lowering seal, wherein the activation unit has a first contact surface, a pivotable contact element and a pivotable force transmission element. The contact element contacted when closing the door leaf, the first contact surface and moves during the closing movement of the door wing under pivoting of the contact element along the first contact surface. A pivoting movement of the contact element results in a pivoting movement of the Kj-aftübertragungselements, whereby the force transmission element actuates the lowering seal.

In this text, terms such as "up" and "down" designate the directions in which the sealing strip of the lowering seal moves. "Up" is thus the direction in which the sealing strip is raised and retracted into its housing rail, "down" is the direction in which the sealing strip lowered in order to seal the door gap, so gefaliren out of its housing rail out. The direction "downwards" preferably refers to the direction of the gravitational force, that is to say to a building floor, in cases where the gravitational direction is necessarily meant noted in the text.

If, in the following, contacting by a contact surface is used, then the respective contact can be point or line-shaped and does not have to be flat.

According to the invention, the second contact surface of the contact element moves, preferably rolls, along the first contact surface in a sliding manner. As it unrolls, it thus unwinds along the first contact surface and each point of the first contact surface is contacted with another point on the second contact surface.

The expended during the closing of the door force is thus minimized, the design of the two contact surfaces and the position of the first pivot axis can be chosen so that an optimal power transmission for lowering the sealing strip can be achieved.

Preferably, the first contact surface is directed upward and the contact element is located on closing of the door leaf on this first contact surface, wherein it slides along this, preferably unrolls, and thereby actuates the lowering seal. Preferably, the direction indication "upwards" in this context refers to the direction opposite to the gravitational force.

The upwardly directed first contact surface (taking into account the direction of the gravitational force) has the advantage that the weight of the door leaf presses partially or completely onto the contact element. A person closing the sliding door must apply relatively little or no additional force to lower the sealing strip. The sliding door can be closed despite the lowering seal without increased effort.

Preferably, the contact element is connected to the actuating mechanism or operatively connected. It may also be itself a part of the actuating mechanism.

Preferably, the first contact surface and the contact element are formed so that when closing the door leaf upwards, preferably opposite to the gravitational force, acting force is obtained, which is deflected so that they on the actuating mechanism acts.

The inventive arrangement is preferably arranged on the side of the auxiliary closing edge of the sliding door. However, it can also be arranged at the main closing edge.

Like the actuating mechanism, the activation unit preferably consists exclusively of mechanical means and preferably does not comprise any magnets and / or electric motors and / or sensors. Since the first contact surface can be arranged in the sliding direction next to the lowering seal, the sealing strip can extend over the entire length of the door leaf and it can thus seal optimally.

Another advantage is that the activation unit holds the sealing strip in a lowered position, without the restoring force influencing a sliding movement of the door leaf in the longitudinal direction of the sealing strip. As a result, no additional locking mechanisms are necessary to keep the door in its closed position. Furthermore, the restoring force of the lowering seal does not hinder the complete closing of the sliding door. Many sliding doors have a braking mechanism due to their great weight, which slows down the closing movement of the door leaf shortly before reaching the full closing position. This prevents fingers or other parts of the body from getting caught too tightly. In preferred embodiments of the invention, this braking mechanism should not be influenced by the restoring force of the lowering seal or by the force necessary to lower the seal. It should additionally or alternatively not even more force to close the door must be spent. In these embodiments, therefore, the lowering seal can be fully lowered before reaching the full closing position and hold in this position without further external effort. The sealing strip grinds over the ground during the further closing movement, but only over a short distance. Preferably, a position of the contact element on the first contact surface is present, in which position the sealing strip is completely lowered and in which position the restoring force acting on the sealing strip in a direction perpendicular to Longitudinal direction of the sealing strip is deflected.

Preferably, the first contact surface extends at least partially in the longitudinal direction of the lowering seal in an oblique direction, preferably extending in the closing direction of the door leaf from bottom to top. The slope can be constant or changing. By means of the slope, the force can be adjusted, which must be used to lower the sealing strip. It can thus choose power translations to optimize the force required.

Preferably, the first contact surface has a horizontally extending portion on which the contact element rests to hold the sealing strip in the lowered position. The horizontal section preferably adjoins the inclined section. The door leaf can be completely closed by the contact element first moves up the inclined surface while lowering the sealing strip and then moved along with lowered sealing strip along the horizontal surface until the door is on the door frame laterally.

In preferred embodiments, the contact element actuates the actuating mechanism to lower the sealing strip. It can do this directly or indirectly, for example by means of a power transmission element.

Preferably, the contact element is fixedly connected to the Absenkdichtung and the first contact surface is formed in a separate from the Absenkdichtung module for placement in a stationary part of the sliding door. Preferably, the second contact surface is curved over its entire length. In alternative embodiments, it has one or more plane intermediate regions. Preferably, only the second contact surface is curved and the first contact surface has a planar surface, which obliquely and / or running horizontally. With the choice of the slope of the first contact surface, the power transmission can be adjusted.

The first or second contact surface preferably has a length over which the contact element contacts or rolls, the curvature of the first or second contact surface having a radius of curvature that changes over this length. Preferably, the curved surface forms an involute.

Preferably, the contact element is pivotable about a first axis and the force transmission element about a second axis. Preferably, the axes are not identical. The first axis is preferably arranged perpendicular to the longitudinal direction of the lowering seal and perpendicular to the lowering direction of the sealing strip, and the second axis runs parallel to the first axis. Preferably, the first axis is arranged eccentrically with respect to the second contact surface in the contact element, wherein the contact element has a base body and a Kontaktierungsarm arranged thereon and wherein a free end of Kontaktierungsarms when closing the sliding door, the first contact surface first contacted. This optimizes the leverage and thus minimizes the effort.

Preferably, the force transmission element is operatively connected to the contact element, wherein the force transmission element actuates a actuating button of the actuating mechanism via a third contact surface when closing the door leaf. Preferably, the force transmission element is pivotable about the second axis when closing the door leaf. Preferably, the second axis is arranged eccentrically with respect to the third contact surface. The third contact surface is preferably curved and preferably forms an involute. Power transmission element and contact element are operatively connected to each other differently depending on the embodiment. They can be connected to each other, for example via pivot axes and / or levers. Preferably, however, the contact element and the force transmission element are in intermeshing engagement in particular, they are partially formed as gears. This is a simple, space-saving and cost-effective way of transmitting power. Preferably, the main body of the contact element and the force transmission element are formed at least over part of its circumference as gears.

Preferably, the first axis is arranged perpendicular to the longitudinal direction of the lowering seal and perpendicular to the lowering direction of the sealing strip. Preferably, the second axis is parallel to the first axis. In preferred embodiments, the power transmission element has a base body and a laterally displaced to the body Kraftübertragungsann, wherein the power transmission arm activates the actuating mechanism. Preferably, the transfer arm has the curved third contact surface for contacting the lowering mechanism, in particular the subsequently mentioned actuating button.

In preferred embodiments, the operating mechanism of the lowering seal comprises an actuating button which activates the actuating mechanism by external force. Preferably, the contact element acts mediately or directly on this actuating button and thereby lowers the sealing strip. Preferably, the power transmission element, more specifically its power transmission arm, and more particularly the third contact surface, acts directly on this actuating button. Since many known Absenkdichtungen have such a control knob, the inventive activation unit can be used with these known Absenkdichtungen without the latter must be substantially changed.

In preferred embodiments, the Absenkdichtung on a housing in which the sealing strip is held raised and lowered. The actuating knob can protrude this housing frontally. In other embodiments, it is aligned with the end face of the housing or it is arranged set back. The recessed arrangement is the most preferred. Preferably, it is displaceable relative to the housing in the longitudinal direction of the sealing strip.

The force transmission element preferably acts on the front side of this actuating button usually, by pressing it in the middle or immediately after closing the door and releasing it when the door is opened.

The erfmdungsgemässe activation unit can also be used with other types of Absenkmechanismen, the contact element on a suitable location of Absenkdichtung middle or directly applied.

The stated object is also achieved by a sealing device of a sliding door with a slidingly mounted door, which has a lowering seal with a sealing strip and with an actuating mechanism for automatically lowering and raising the sealing strip, the lowering takes place against a restoring force. The sealing device has an activation unit for activating the lowering seal, wherein the activation unit has a contact element which, when the door leaf closes, contacts a first contact surface of the activation unit and thereby actuates the lowering seal. The activation unit has a force transmission element. The contact element is designed to be pivotable about a first axis and the force transmission element is designed to be pivotable about a second axis. The contact element and the force transmission element are in meshing engagement with each other, so that when closing the door leaf, a pivoting movement of the contact element about the first axis results in a pivoting movement of the force transmission element about the second axis. The power transmission element actuates when closing the door leaf by its pivoting movement, the lowering seal. Since the contact element and the force transmission element mesh like gears, a space-saving and cost-effective design of the activation unit is possible, the advantages of contacting a first contact surface are still present, especially if it is oriented upwards and especially if they have a sloping and has a horizontal portion. Preferably, and even more preferably, when closing the door leaf, the contact element slides with a second contact surface along the first contact surface. The features mentioned above in the chapter "Presentation of the Invention" as well as the features of the dependent claims can also be achieved with this device Optionally combine consideration of all features of claim 1 to obtain the advantages already mentioned.

The lowering takes place counter to a restoring force. The sealing device has an activation unit for activating the lowering seal, wherein the activation unit has a contact element which contacts a first contact surface of the activation unit when closing the door leaf and thereby actuates the lowering seal. The activation unit has a pivotable force transmission element, which is operatively connected to the contact element. The power transmission element has a curved contact surface, which actuates an operating knob of the actuating mechanism during the closing of the door leaf in order to lower the sealing strip.

The curved configuration of the contact surface enables optimum force transmission to the actuating button, in particular if it forms an involute, and in particular if the pivot axis of the force transmission element is arranged eccentrically to this contact surface. This sealing device can be combined without using all features of claim 1 with the features of the dependent claims.

DESCRIPTION OF PREFERRED EMBODIMENTS

FIGS. 1 to 5 show a first exemplary embodiment of a sealing device according to the invention. In Figures 4 and 5, some elements, such as the housing rail 10 and the additional wall 100 for better readability of the figures are not shown.

The sealing device has a lowering seal 1 of a known type, as described, for example, in the introduction. The lowering seal 1 has a housing rail 10, which is fastened by means of known means, here by means of a frontally inserted into a groove of the housing rail 10 mounting bracket 13, in a lower groove of a sliding sliding door leaf. Other types of attachment, for example by means of lateral brackets, are also possible.

The housing rail 10 is formed in contrast to the prior art not only hat or U-shaped to form a first chamber downwardly open. It preferably has a second chamber, which is bounded by an outer additional wall 100. In the first chamber, a sealing strip is lowered and held liftable. For this purpose, a likewise arranged in the first chamber mechanical actuating mechanism of known type is present. It is often called a lowering mechanism. It is not shown here, but known from the prior art. Preferably, it has one or more leaf springs, each of the leaf springs being fastened to the housing 10, to the sealing strip and to a slide 15. The slider 15 is connected to an actuating knob 14, which at least on one side, preferably only on one side, the housing rail 10 is arranged. He may project the housing rail 10, aligned with its front side or arranged set back. If the actuating button is arranged inside the housing 10, it can be displaced by pressure or tension. However, it can also be contacted and moved, for example, through a lateral or upper window in the housing rail 10. For actuating button alternative triggering mechanisms can also be used in the inventive sealing device. Also, the inventive teaching without such a second chamber and without additional wall 100 can be realized. The sealing strip preferably has a carrier rail 12 and an elastomeric sealing profile 11 attached thereto. The housing rail 10 and the support rail 12 are preferably made of aluminum or other suitable metal. The sealing profile 1 1 is preferably made of rubber or silicone. The sealing profile 1 1 seals in the lowered state of the sealing strip a gap between the bottom of the door leaf and a floor.

The sealing device according to the invention furthermore comprises an activation unit for activating the actuating mechanism of the lowering seal. Preferably, the activation unit acts on the actuating button 14 of the lowering seal, preferably by pressing it. Depending on the activation unit and operating mechanism, it can also move or pull out the button to lower the sealing strip.

As can be seen in Figure 2, the activation unit has a contact module 2, which is designed here as a support module. This contact module 2 is arranged next to the lowering seal 1. It is stationary fixed preferably on the floor B or on a building wall or on the door frame. The existing through holes are provided with the reference numeral 24. It can also be mounted in other ways, for example by latching in an upwardly open C-rail.

The contact module 2 is located next to the lowering seal 1, wherein it is received when moving the door leaf in the second chamber, formed by the additional wall 100 of the housing rail 10. The contact module 2 is formed in this example as an angle element, wherein it is fastened with a leg on the floor or door frame and the second leg projects upwards. The contact module 2 has an upwardly directed first contact surface. The first contact surface is formed here as a bearing surface. In this example, it has an inclined surface 21 and an adjacent horizontal surface 22. The contact module 2 further has an upwardly projecting guide lug 23, which is introduced upon closing of the door leaf in the second intermediate space between the additional wall 100 and the housing rail 10.

Preferably, the contact module 2 made of plastic, metal or a coated metal or wood.

The activation unit further comprises a power transmission module which is arranged with the lowering seal on the sliding door leaf. It comprises a contact element 3 and a force transmission element 4, which are both pivotable about an axis 30, 40. The axes 30, 40 are held in the housing 10, 100 of the Absenkdichtung. In the region of this power transmission module, the housing rail preferably has a passage window in the second chamber

The first axis 30 of the contact element 3 and the second axis 40 of the force transmission element 4 are preferably arranged perpendicular to the longitudinal direction of the lowering seal and preferably perpendicular to the lowering direction of the sealing strip. They run parallel and offset from one another. The first and / or the second axis 30, 40 are arranged eccentrically in relation to their contact surfaces 320, 420 in the corresponding element 3, 4.

The contact element 3 has a main body 31 and arranged thereon, the contact element 3 extending Kontaktierungsarm 32. The contacting arm 32 preferably extends in the same plane as the main body 31.

The contact element 3 is preferably in one piece and preferably made of plastic or metal. An outer jacket section of the contacting arm 32, together with an outer jacket section of the main body 31, forms a second contact surface 320 which is continuous and preferably forms an involute. The second contact surface 320 preferably has a radius of curvature that changes over its length. Depending on the embodiment, planar regions are also possible, wherein a curvature that is present over the entire length of the second contact surface 320 is preferred.

The main body 31 has some teeth 310 of a gear. These engage toothed teeth 410 of the power transmission element 4. These latter teeth 410 are integrally formed on a base body 41 of the force transmission element 4. Also, the power transmission element 4 is preferably in one piece and preferably made of plastic or metal. It has a power transmission arm 42, which forms an extension of the main body 41, but offset in the direction of the second axis 40 is arranged. This Kraftübertragungsarm 42 has a third contact surface 420, which is executed to the operating knob 14 and contacts this when closing the door leaf. This third contact surface 420 may be planar. Preferably, however, it is also curved. As can be clearly seen in FIGS. 2 and 4, the teeth 310, 410 of the contacting element 3 and of the force transmission element 4 are aligned so that the teeth 410 of the force transmission element 4 in the closing direction of the door leaf and the teeth 310 of the contacting element 3 are aligned opposite thereto. The closing direction of the door leaf is indicated in the figures with an arrow.

With reference to Figures 2 to 4, the operation of this seal assembly is clearly visible. When the door leaf closes, it slides over the stationary contact module 2, which is fixedly arranged on the secondary closing edge. The guide nose 23 serves as a guide for the sliding door leaf. Shortly before the closing of the door leaf, the power transmission module 3, 4 reaches the contact module 2. The contact element 3 rests with its Kontaktierungsarm 32 and more precisely with its second contact surface 320 on the first contact surface, ie first on the inclined surface 21 and then on the horizontal surface 22nd It lies on this first contact surface, whereby the Contact element 3 when closing the door leaf slidably moves on the contact module 2, wherein it rotates by the movement along the inclined surface 21 about the first axis 20. Due to the pivoting of the contact element 3 about the first axis 30, the force transmission element 4 is rotated thanks to the teeth. The power transmission arm 42 is pressed against the operating knob 14 and presses it into the seal. This is the activation of the actuating mechanism of the seal. The leaf springs are tensioned and the sealing strip is lowered.

On the horizontal surface 22, the contact element 3 preferably slides without further pivoting movement, so that no further power transmission takes place on the lowering mechanism. The lowering thus takes place during the movement on the inclined surface 21. If the horizontal surface 22 is reached, although the door can still move depending on the training, the seal is already lowered.

The contact element 3 rests with the contacting arm 32 on the horizontal surface 22. Because the force vector is at 90 ° angle, it is prevented that the restoring force of the actuating knob 14 can push open the door again.

Thanks to the eccentric arrangement of the first and / or second axis and the shape of the second contact surface 320 of the contact element 3 is achieved that when closing the door the knob 14 is first moved over a small path and the further closing the way to which the button 14 is pressed in comparison to the closing path of the sliding door leaf, is greater.

The power transmission module 3, 4 is arranged at least partially frontally in front of the lowering seal. So that the usual settings can be made on the lowering seal, such as adjustment of the stroke, the force transmission element 3 has a passage opening 43. This is clearly visible in FIGS. 5 and 8. In addition, a stop 5 is present in the region of the contacting element 3, here in the form of a pin. The contacting element 3 can be pivoted into a position until it abuts against this stop. This is clearly visible in FIG. In this position, the through hole 43 of the power transmission element 4 is aligned horizontally and forms a passage to a thread 140 of the actuating knob 14. With a corresponding tool, such as an Allen wrench, now the through hole 43 can penetrate and the basic position of the actuating knob 14 in the longitudinal direction can be Set in a known manner by appropriate rotation, the elements of the power transmission module are held by the stop 5 almost free of play in position.

A further adjustment can be achieved by changing the height of the contact module 2 and / or the slope of the inclined surface 21. This can be achieved, for example, by offering a set of differently shaped contact modules 2 with a lowering cable. Such a set consisting of two elements 2 is shown in Figures 15 and 16.

These sets can also be used with the second embodiment described below, which is shown in Figures 6 to 14.

The individual elements correspond to the elements of the first embodiment and are therefore not explained in detail. Identical parts are provided with the same reference numerals. However, the arrangement of the contact element 3 or its teeth 310 and of the force transmission element 4 or its teeth 410 are different. In this example, the teeth 310 of the contact element 3 are in the closing direction of the sliding door in front of those of the power transmission element 4 and terminate in the closing direction. Thus, the contact element 3 is in the closing direction behind the power transmission element 4. The gear of this arrangement is thus better protected to the outside, since it is covered by the power transmission element 3, in particular by the Kontaktierungsarm 32. As can be clearly seen in Figures 9 and 10, the stopper 5 is in turn present, but arranged at another suitable location. Figures 7 to 9 show the situation with still partially open door and not yet lowered sealing strip, Figures 11 to 14, the situation with the door closed and lowered sealing strip. In Figure 6, the power transmission module 3, 4 is pivoted such that the passage opening 43 is brought into the horizontal adjustment position.

In the figures 13 and 14, a guide sleeve 16 is also clearly visible, which surrounds the actuating knob 14 at least over part of its length and which is fixed to the housing rail 10. This guide rail 16 ensures that the actuating button 14 is displaced only in the longitudinal direction of the lowering seal despite acting on him from the pivoted force transmission arm vertical force components. This guide sleeve 16 can also be used in the first embodiment and in other examples not described in detail here. The erfmdungsgemässe device allows a relatively simple design, robust and yet extremely effective sealing device for sliding doors, wherein the force required to lower the seal is minimized and the sliding door is held in the unlocked position in its closed position.
