Description

The The present invention relates to a fitting for braking of relative movements between device parts, in particular movements of sliding doors or other doors or furniture parts. In particular, furniture parts come into consideration like flaps, drawers or doors, especially cabinet doors and furniture-independent doors, such as in room division systems. Also cooling facilities, z. B. in large grocery stores and supermarkets can corresponding door systems, especially of course Sliding door systems.

It has long been known to mechanically dampen movements, For example, the input and / or pull movements of a furniture drawer or a sliding door. This is to prevent that a drawer or sliding door because of something too violent Operation overly fast opened or closed and with noise and Shocks connected to a respective end stop encounters. Such incorrect operations can through lack of mindfulness, but also through wrong intuitive assumptions about the loading condition of the drawer or the mass of the door and thus excessive forces during operation arise.

Also It may be desirable to have a large sliding door or heavily laden drawer, because of inertia has to be accelerated with a certain force in order to or to start opening movement, not undamped or unrestrained to drive in the opposite position. Just Heavy sliding doors are used to speed up the door larger forces required, it being uncomfortable for the user, the door in front having to catch the end stop manually.

Analogous considerations apply to many other use cases, for example the opening and closing of other moving Furniture parts such as doors or flaps, for Window sash or room and front doors in draft as well as for shutters, especially for Furniture, etc. These areas are conceivable and preferred, however, not exclusive areas of application of the Following explained invention.

Examples of a known structure of such a damping device can be found in the WO 2006/056606 , These known and other damping devices use a pneumatic damper to brake a device part, for example a sliding door, in the end region of its movement. Conversely, the sliding door must be able to detach from the mechanism. For this purpose, various transfer mechanisms are known in the prior art.

Of the Invention is based on the technical problem, a simple and practical fitting for braking moving parts of the device specify.

The invention is directed to a fitting for braking a movement between two relatively moving parts of the device with two complementary fitting parts, which are designed to build during a relative movement of the device parts in an end position a braking friction between each other by conditioning respective surfaces together the friction is a rubber-elastic body of one of the fitting parts involved, and during the braking, a friction-enhancing movement takes place along an inclined to the direction of the braked motion surface of the fitting,
on a correspondingly designed sliding door system and on the use of the fitting for sliding doors.

According to the invention for braking the relative movements of device parts, the friction used between surfaces used for this purpose in Plant are brought together. At least one of the surfaces belongs to a rubber-elastic body. moreover takes place during the braked (rest) movement along a movement an oblique surface of the fitting. This movement reinforced along the sloping surface the friction, so the friction surfaces leads closer to each other or presses them with larger Power each other. The friction dissipates the kinetic energy and at the end of the movement, the device parts are relatively formed mutually determining frictional engagement or adhesion. The water traction and at least part of the braking friction must be overcome again when the fitting parts are detached from each other and the Device parts are moved relative to each other.

With This concept is the fitting according to the invention much easier to realize than the one described above State of the art. In particular, the comparatively more expensive pneumatic dampers by a simple surface friction replaced. This is done by or during the braking process reinforced by the movement along the oblique Surface done. By picking up the plant is in particular easy way, a release of the two device parts from each other possible (which does not exclude other couplings are).

The rubber-elastic body has proven particularly useful in this context, because the elastic deformation during the braking process enables a particularly good conformance of the abrading surfaces, and provides many suitable elastomeric materials with relatively "matte" surfaces, ie surfaces well suited for relatively high sliding friction of another surface thereon.

Preferably is the mentioned oblique surface at one provided the two rubbing surfaces themselves; in In other words, this surface is related to the direction of movement the relative movement of the device parts tilted something. The embodiment shows vividly that by this inclination progressively to be braked movement first a plant is made and then the pressure of the two surfaces on each other is enlarged.

there can be the sloping surface on the rubber elastic Body be appropriate, as the embodiment also shows. It could also be the counter surface to a surface of the rubber-elastic body act. Incidentally, embodiments are with rubbing surfaces, both surfaces rubber-elastic Bodies are also not excluded.

A Another preferred embodiment provides a longitudinal displacement of the elements that are to be brought into the surfaces wear. With Längsverschieb probability is natural a displaceability with respect to the respective remaining fitting part meant and not the basically given mobility the two device parts to each other. The longitudinal displacement is limited between two attacks. At the beginning or in the During the braking process, the longitudinally displaceable element from the other surface, ie the counter surface, taken, but preferably not mandatory until the stop and when loosening the fitting parts withdrawn from each other again. This longitudinal displacement is without or at lesser Surface friction covered a distance and doing the friction-enhancing effect of already mentioned movement along the inclined surface caused. The longitudinal displacement should therefore the Reinforce the effect of the sloping surface or bring to bear. For illustration will be up again referenced the embodiment, where there is a preferred Variant is shown, namely in the oblique Area a guide surface for is the longitudinally displaceable element just treated. The movement is along the longitudinal displacement the oblique surface generates and the corresponding element moved to the opposite surface or to this stronger pressed.

in this connection It should be noted that the guide along the sloping Surface, as the embodiment shows with another inclined surface on the guided Element may be connected, namely the concrete for the friction-designed surface. In the embodiment find in this sense two movements along an oblique Area instead, on the one hand, the longitudinally displaceable Elements along its leadership, on the other hand, the corresponding Counter surface along the designed for the plant Surface of the rubber-elastic body or longitudinally displaceable guided element.

The already explained details may be particularly be realized favorably in a design of fitting parts with on the one hand a hollow seat and on the other hand an engagement projection. Of the Engagement projection is for insertion into the hollow seat designed to be one of the two surfaces to be brought into contact carries and the other of the surfaces in the hollow is arranged. For example, as in the embodiment, in the hollow receptacle an element, in particular the rubber-elastic body, longitudinally displaceable on an inclined surface be guided.

Preferably is the engagement projection in at least one dimension and especially preferably in two dimensions narrow, so a plate or a pen (being "narrow" in proportion to the length of the engagement in the hollow receptacle understands). A pin can also be a rejuvenated end for relief of insertion into the hollow seat and preferably followed by a substantially parallel longitudinal section profile, ie a constant strength.

A further improvement of the invention may consist in a cavity, which is adjacent to the rubber-elastic body, on a side opposite to the system. Thus, the rubber-elastic Body in the cavity dodge something when passing through the system is under pressure, and in this form especially react softly and yieldingly. This is especially true locally. So is in the embodiment of this cavity with respect to the extension of the rubber-elastic body along the direction of movement arranged centrally and the rubber-elastic Body in the middle effectively softer than his Edges.

For example can be realized by the holder of the rubber-elastic Body on a U-profile shape (in relation to a section along the direction of movement). Close two relatively short legs of the U. while the cavity between them. The rubber-elastic body can then be a simple flat cuboid. The U-profile bracket in turn, can be guided longitudinally displaceable, especially at the already mentioned oblique Area.

Of the already frequently used term is "oblique" in the context of this invention preferably to be understood that in longitudinal section along the direction of movement and relative to the direction of movement an angle of at most 20 °, preferably at most 15 ° and more preferably Way at most 10 °. This angle is while facing the other fitting part, as the embodiment illustrated.

Further Aspects of the invention relate to sliding door systems with a inventive fitting or use the same for such a sliding door system, at so that the door element or door leaf translational is moved to close the door opening or release. Sliding door systems are used in the Furniture construction, in the case of room or front doors, with room dividers, Also for the demarcation of walk-in cabinets, refrigerators or spaces, but also with larger ones Hall gates, garage doors u. Ä. Depending on the application difficult to move the sliding door elements.

The Invention is also directed to a sliding door system with a fitting according to the above description, in particular on the one hand on a rail for holding and on the other hand on the sliding door element is attached, in such a way that the fitting by the rail covered in the vertical direction of the sliding door element is.

The The basic idea is that in the vast majority of common Sliding door systems are anyway provided rails, the not only hold the sliding door element, but also with a rail leg at least one space above the corresponding Cover and cover the side edge of the sliding door element. Here, the line of sight is on the sliding door element, ie perpendicular with respect to its areal extent, meant. "Hold" does not necessarily mean here that the rail is the whole weight or even only carries the weight of the sliding door element, but also refers to such cases where the rail for example, only against unwanted lateral movements, so to speak, in the mentioned line of sight, is provided and insofar the sliding door element in the Train stops.

The Rail can include with its leg the side edge itself and cover or also, as seen in the horizontal direction, in Essentially connect to the side edge. Then cover They leave a space above the side edge, which is for mounting element u. Ä. Use and therefore protected from view shall be. Of course it can have a small slot so that the term covering only in the sense of a "substantially Cover "is to be understood.

If now this rail is also used to cover the fitting, by placing it inside the rail, they are otherwise observed in the market deterioration of the outer Appearance avoidable by damper constructions. For this, the rail does not even have to be a little bigger Have dimensions as otherwise necessary.

Prefers is the fitting between the rail and the sliding door element assembled. This is not necessary. You think For example, an inverted L-profile, with a leg is mounted horizontally on a ceiling and with the other vertical leg in the manner described at least the space over the side edge covers, and you also think of this L-profile in front of a wall, so in a corner, mounted, so could the fitting also quite between the sliding door element and the room wall be appropriate. According to the invention preferred However, solutions are independent of such Mounting situations provide a visual cover and thus provide the fitting between rail and sliding door element. In consideration come with the described L-profile shape thus the gap between the horizontal leg of the "L" and the sliding door element, so to speak one Mounting of the fitting "over" the sliding door element, and the gap between the vertical leg of the rail and the sliding door element, so to speak an assembly "in front" of the sliding door element. Preference is, even with other profile shapes, a mounting "over" the Sliding door element, ie between a horizontal leg the rail or its upper wall, and the sliding door element. Also preferred are rails in an inverted U-shape, ie compared to the described L-shape another vertical Have legs.

The Rail can be bearing for storage of the sliding door element in the slidable manner in the rail, such as systems with guide rollers and treads for these. This applies both to the one already mentioned Case that the holding by the rail only a lateral Leading in a course corresponds, as well as for the case of a support of a part of or the whole Weight of the sliding door element.

It is further preferred that the fitting in a solution according to the invention is mounted on an upper rail, although sliding door systems usually additionally also have lower rails in the floor area. In the lower rails are a minimum size and therefore often no additional mechanical effort desired. Furthermore, they are particularly well accessible even when viewed from above, when there is a visual coverage in the (horizontal) direction perpendicular to the sliding door element level.

Prefers is in the context of the invention finally an application in the field of sliding door systems with particularly heavy Sliding door elements, as with room dividers, departments walk-in closets, gates and room and front doors occur outside the actual furniture. It is therefore preferred to sliding door systems, which are mounted on room or house walls.

in the The invention will be described below with reference to exemplary embodiments explained in more detail, with the individual features also in other combinations may be essential to the invention and basically refer to all claim categories.

1 shows in four individual views a braking operation in a sliding door system, which is equipped with a fitting according to the invention.

2 Complementary to the process of moving out of a fixed position by the fitting.

1 shows over each other four individual representations with the same parts, but at different successive time pumps. It is simplified in horizontal side view, the retraction of a sliding door 1 shown in a final position reached in the last detail view. The single view on the top left is also a schematized view in a horizontal direction, but rotated by 90 °, ie seen in the direction of movement.

It can be seen here a "hanging" sliding door shown here only with its upper left corner area 1 that over a pin 2 on a carriage 3 hangs. The view shown in the direction of movement top left shows that the carriage 3 on both sides wheels 4 has, which are provided on the right side in the side view recognizable in pairs. With these four wheels in total 4 the car is running 3 in a recognizable in the small illustration top left running rail 5 having for this purpose an inverted U-profile, the U-legs in each case a slightly curved extension as a running surface for the wheels 4 wear. In this form can be the sliding door 1 along the track 5 drive back and forth. It can be performed at the same time at its lower end, not shown, and even supported, but also hang freely at the bottom.

At the front in the figures in the direction of travel (ie in the four superimposed individual representations left) end of the car 3 is an approach 6 with a pin-like engagement projection 7 attached, which projects in the direction of movement and at its extreme end with a tip 8th is rejuvenated. This may be a plastic injection molded part. A metallic version is also suitable. The approach 6 can be attached to existing rolling systems by screwing or other joining techniques. Incidentally, the approach 6 especially in sliding door systems without a pin 2 in which the sliding door 1 even up to or in the visible area, right on the sliding door 1 be attached.

Unlike this one with the car 3 and with the sliding door 1 moving pen 7 is also in the rail 5 a box-like hollow seat 9 attached, as viewed in the direction of movement top left but not shown. The hollow receiver 9 has an attachment section at its left end 10 with two mounting holes for mounting on the rail 5 , The mounting holes are shown only symbolically and could run in a favorable manner vertically in this case. Incidentally, the approach can 6 with the engagement projection 7 on the one hand and the hollow seat 9 on the other hand also be reversed.

Incidentally, the hollow seat 9 an inner cavity with a relative to the horizontal by about 4-5 °, preferably max. 10 ° tilted sloping roof surface 11 on, as well as arranged at its lower right portion insertion 12 to retract the pen 7 ,

On the sloping surface 11 lies a U-profile beam 13 on, wherein the U-legs are flat and truncated. This U-profile beam 13 is, as the figures show each other in comparison, along the oblique surface 11 guided longitudinally displaceable and lies in the upper two representations in the guide right outside and in the lower two representations on the left outside. The guide can be accomplished simply by projecting the U-profile support up and down slightly beyond the cavity in a direction perpendicular to the plane of the drawing, and engaging in slots, the rear of which is indicated in the figures.

The U-profile beam 13 By the way, it has a rubber-elastic body on its underside 14 , the flat cuboid with approximately the same basic dimensions as the U-profile beam 13 minus the guide projections. Its bottom surface is with 15 denotes and increases the already mentioned skew angle by about 1 °. The U-profile beam 13 can be just like the pen 7 made of a harder plastic or metal; the rubber-elastic body 14 preferably consists of a sprayable thermoelastic elastomer, a natural rubber or synthetic rubber material or silicone.

The sequence of individual representations illustrates how it works: Top is the pen 7 including its top 8th still from the hollow seat 9 disconnected and moves with the sliding door 1 towards it. In the second representation from above is the top 8th already in the insertion opening 13 penetrated and has along with the foremost area of the section of the pen 7 with parallel longitudinal profile already an investment on the lower inner boundary surface of the cavity and especially on the lower surface 15 of the rubber-elastic body 14 produced.

This system creates a certain frictional engagement, which is why the rubber-elastic body 14 together with the U-profile beam 13 in its longitudinal guidance moved a little further to the left, as the third figure shows from above. As a result, the rubber-elastic body 14 lowered slightly so that the frictional engagement between the pin 7 and its lower surface is reinforced. This also applies to the frictional engagement with the counter bearing, ie the lower inner boundary surface of the cavity.

The inertia of the sliding door 1 pushes the pen 7 further, wherein the friction degrades the kinetic energy. The rubber-elastic body 14 gives in the volume, but above all bending upwards and bends slightly into the cavity between the two U-legs of the wearer 13 high, like the lowest chart in 1 shows. In this state, the pen remains stuck more or less penetrated, with the in 1 left U-legs of the wearer 13 at the very end of the possible path of movement for the pen 7 provides a relatively large frictional resistance. This will prevent a "punch through" of the pen when the sliding door 1 is moved up with a lot of momentum.

Overall, in this form the sliding door 1 effectively and "softly" braked and fixed in their final position. The end position can be achieved by fixing the hollow seat 9 within the rail 5 be set or changed. A corresponding embodiment is of course also at an opposite end position of the movement path of the sliding door 1 possible, for which purpose preferably another car 3 at the opposite upper end of the sliding door 1 equipped with a corresponding fitting.

2 shows a movement with the direction reversed, ie a release of the sliding door 1 according to their anchorage 1 below. The five individual representations correspond to 2 in terms of the manner of presentation those in 1 , In particular, the top right individual representation corresponds to 2 the lowest in 1 and corresponds to the lowest individual representation in 2 the top right in 1 ; Furthermore, the view in the direction of view along the direction of movement top left is identical to the in 1 ,

However, the second individual representation counted from above shows in 2 apart from the rightward movement of the sliding door 1 and the car 3 a significant difference between the driving in of the pen 7 in the hollow receptacle 9 and pulling out. One recognizes that this from the highest single representation in 2 For the second-highest single representation was slightly pulling out of the pin initially especially the U-profile beam 13 withdrawn in its longitudinal displacement. The friction of this longitudinal guide is namely significantly lower than the friction between the pin 7 and the surfaces touching it in the hollow receptacle 9 , especially the lower surface 15 of the rubber-elastic body 14 , This retraction of the U-profile beam 13 reduced due to the oblique orientation of its guide surface 11 the vertical pressure on the friction surfaces and, to recognize the comparison of the top and second top view in Figure, the bending of the rubber-elastic body 14 in the cavity above. Accordingly, the pin can be 7 in the episode, that is, in the step from the second to the third highest representation in 2 , lighter from the hollow 9 pull out to this then, as in 2 shown to leave completely.

The longitudinal displacement along the inclined surface thus ensures when driving in and clamping the pin 7 or more generally, the engagement projection for increasing the friction by increasing the pressure and reducing the friction during withdrawal accordingly reversed. Because of the much higher friction between engagement projection 7 and associated mating surface, here the lower surface 15 of the rubber-elastic body 14 , Compared to the friction in the leadership of the longitudinal displacement of the U-profile beam 13 Thus, on the one hand during braking and clamping (with regard to further movement in the insertion direction) high frictional forces and on the other hand comparatively lower frictional forces when moving out in the opposite direction.

It should be noted that the advantageous combination of the longitudinal displaceability with an inclined guide surface is not mandatory for this purpose. example wise, the lower inner boundary surface of the cavity, so the horizontal inner surface in the figures, on which the pin 7 rests, be designed obliquely and could be both the U-profile support and the rubber-elastic body lying horizontally and have horizontal surfaces. Even then, a longitudinal displacement of the latter would allow the pen deeper into the hollow receiving and thus increase the pressure by the inclined surface located in this case under the pin and this friction increase would be reversed by a shift back of the rubber-elastic body when pulling back, because the pin 7 then, for the time being, it would be possible to pull back a little along the slope without (substantial) relative movement to the rubber-elastic body.

It can also be seen that an oblique position of one of the engaging projection 7 clamping surfaces, here the lower surface 15 of the rubber-elastic body 14 regardless of the longitudinal displaceability for an increase in friction with further penetration of the engagement projection 7 ensures and thus is beneficial.

Finally, one recognizes that even an oblique orientation only a guide surface, as here the surface 11 , For a longitudinally displaceable element, which is involved in the frictional engagement, can provide a corresponding increase in the friction. If, in the illustrated embodiment, the lower surface of the rubber-elastic body 14 horizontally, would the engaging projection 7 the rubber-elastic body 14 Nevertheless, take with increasing penetration and thus pressed this horizontal surface by the oblique guide down. In this sense, the wording used in the main claim of a movement along a surface is generally meant and refers in the embodiment both on the inclined surface 11 as well as on the lower surface of the rubber-elastic body 14 , where for the completion of the general sense of the formulation chosen in the main claim already one of the two inclined surfaces would be sufficient. In principle, a movement along an inclined surface on the engagement projection itself would also suffice, but is less preferred.

It can also be seen that the cavity between the two legs of the U-profile bracket 13 for the elastic deformation of the rubber-elastic body 14 helpful, but not necessary. Incidentally, it could also be made, for example, by being on top of the rubber-elastic body 14 itself provides a recess, and, of course, is not necessarily associated with the longitudinally displaceable guide, of course.

Finally, the figures clearly show that not only the car 3 with his four wheels 4 , but also the complete fitting with the engaging projection 7 , the hollow receptacle 9 and their holder 10 inside the track 5 accommodate and thus very effectively "hide". This would apply mutatis mutandis to other types of rails.

There are various possibilities conceivable to adapt the friction properties of the fitting during manufacture, as part of the installation or even after wear. For example, the rubber-elastic body could 14 held in different thicknesses or materials and / or by new body 14 be replaced. Also, the U-legs of the bracket could 13 be thickened by Zwischensetzen (sticking) of small spacers. Also, you could use differently-sized pens 7 to introduce.
