Description

The present invention relates to a stopper device for stopping a sliding leaf of a sliding door and a method for mounting such a stopper device.

It is generally known that sliding doors are used to open door openings in structures and close. These sliding doors usually have sliding sashes, which can be pushed back and forth between a closed position and an open position. It is also known that at least one of these two positions of the sliding leaf can be provided with an end stop with respect to a defined end position. Such end stops are usually stopper devices, which are attached to the ceiling and / or at the bottom of the building. This attachment serves to provide a corresponding abutment counterforce to uniquely define in this way the final position of the sash. Corresponding stopper devices are for example in the WO2010 / 019498 A1 and the DE 199 14 860 A1 disclosed. A disadvantage of the known solutions is that the stopper devices are usually simple rubber stopper. These simple rubber stopper serve to provide an elastic return effect available, and at the same time in the sliding direction to buffer an impact force by the elastic deformation when hitting the sliding leaf. A disadvantage of these solutions, however, is that they are usually specific to the particular situation of use, the particular location and, above all, the explicit training of the Sliding wings are. This means that depending on the type, location and design of the sliding door system a specific buffer must be used as a stopper device. The position of the arrangement, ie a floor screw, a ceiling screw or a Randverschraubung, represents a specific design of the stopper device. Thus, the complexity and the need to vorzuhalten different stopper devices, significantly. The price of a single stopper device also increases.

It is an object of the present invention to at least partially overcome the disadvantages described above. In particular, it is an object of the present invention to increase the versatility of a stopper device in a cost effective and simple manner.

The above object is achieved by a stopper device with the features of claim 1 and a method having the features of claim 12. Further features and details of the invention will become apparent from the dependent claims, the description and the drawings. In this case, features and details that are described in connection with the stopper device according to the invention apply, of course, also in connection with the inventive method and in each case vice versa, so that with respect to the disclosure of the individual aspects of the invention always reciprocal reference is or can be.

A stopper device according to the invention serves to stop a sliding leaf of a sliding door. To ensure this, the stopper device has a mounting body with at least one mounting interface for the attachment of the mounting body to a Building on. In addition, the mounting body is provided with a buffer interface for fixing an elastic buffer body to the mounting body. A stopper device according to the invention is characterized in that the buffer body has a mating interface for attachment to the buffer interface in a first buffer position and at least a second buffer position. In this case, the buffer body has a first buffer portion and a second buffer portion, which are aligned with one another such that in the first buffer position, the first buffer portion and in the at least one second buffer position, the second buffer portion provides its buffering effect for the sliding leaf.

According to the invention, therefore, a particular two-part embodiment of the stopper device is provided. Thus, on the one hand, the mounting body is made available, which is formed on the widest possible use for attachment to a building. By providing a universal mounting interface, it is therefore possible to attach the mounting body substantially in any manner to a building structure via this mounting interface. Such a structure may be, for example, the wall, the ceiling or the floor of a building. Thus, a first step of increasing flexibility is achieved by essentially freeing the mounting interface as a universal mounting interface from any specific mounting location design. In other words, the mounting body can be fixed using the mounting interface substantially free in the environment or in the region of a door opening in a building on this structure.

The separation of the mounting body causes the buffer body is provided in addition to the mounting body. The buffer body is now likewise via an interface, namely the mating interface, attachable to the buffer interface of the mounting body. Decisive for the present invention is that this mounting option allows at least two different attachment positions. These are the first buffer position and the second buffer position. When mounting the buffer body on the mounting body so the operator can select in which orientation and thus in which relative positioning of the buffer body is attached to the mounting body.

This choice makes it possible to choose between at least two modes of action of the buffer body. If the buffer body is fastened in its first buffer position to the buffer interface of the mounting body, this means that accordingly also the first buffer section of the buffer body provides its buffer effect for the sliding leaf. If, in contrast, the second buffer position is selected and, accordingly, an attachment to the buffer interface of the mounting body is performed, the buffer body thus provides the second buffer section in its buffering action to the sliding leaf. This now makes it possible to provide the individual buffer sections with a wide variety of functionalities essentially in any way that the two buffer sections differ from one another, at least with regard to a buffer effect feature. For the purposes of the present invention, a buffering feature is a property of the buffer section that is relevant to the sliding effect with respect to the sliding sash. This can be, for example, the degree of elasticity of the respective buffer section, which accordingly defines the elastic deformation quality of the buffer section upon impact of the sliding leaf. So can one of the two Buffer sections should therefore be made softer than the other buffer section. However, the distinction of the individual buffer sections may also be a geometric distinction. Thus, it is conceivable that the two buffer sections differ with respect to their geometric orientation or with respect to their geometric extent and are thus adapted to different geometries of the sliding door system in the whole and the sliding sash in detail.

From the above explanation, it is apparent that the flexibility of a stopper device according to the invention is significantly increased. Thus, a universal mounting interface can lead to a universally usable mounting body is provided accordingly. In addition to the possibility to choose between different buffer bodies, a flexibility can now be integrated in a single buffer body. This flexibility allows the operating personnel or the fitter of a stopper device according to the invention to select a selection between at least two different buffer effects on a single component, namely on the single buffer body. This selection can now provide different buffering effects in terms of their geometry or other parameters of the buffer functionality selectable by the installer of the sliding door.

As a material for the buffer body, a uniform material, for example, a rubber material is preferably provided. The buffer section or preferably the entire buffer body is substantially elastic and can be made of a rubber material, for example. Advantageous hardening of the buffer body or the two buffer sections are in particular in the range between 50 Shore and 80 Shore.

The associated fasteners, so the attachment via the mounting interface on the building and / or the attachment between the buffer interface and the mating interface of the buffer body may be formed in particular reversible. This not only allows a switching between different buffer functions by reorienting or repositioning between different buffer positions to allow, but also perform a wear replacement of a buffer body.

A stopper device according to the invention is therefore easy and inexpensive with high flexibility in a variety of different sliding doors used. At the same time, the complexity in maintaining or in storage is significantly reduced, since a wide variety of sliding doors can be operated with one and the same stopper device.

It may be advantageous if, in a stopper device according to the invention, at least one of the buffer sections, in particular all buffer sections, has at least one centering section for centering the sliding leaf when contacting the buffer section. A centering section forms part of a buffer effect or an additional part of such a buffer effect. Thus, a centering section is a function which, for example, defines the exact position of the sliding leaf in the respective end stop or the sliding leaf during movement by means of centering surfaces moved to its end position in the end area led into this position. Such a centering leads to the fact that the End position not only in the sliding direction, but preferably also in another orientation in addition, in particular transversely to the sliding direction, is exactly definable. For example, when the relatively high-speed sliding sash moves to the end position in which the stopper device according to the present invention is located, the centering portion makes it possible to guide the sliding sash centering portion before reaching the end position. This centering takes place, for example, by contacting the centering section in the last movement part of the sliding leaf during the associated movement into the end position. In addition to a defined positioning a vibration of the sliding leaf is avoided transversely to the sliding direction of the sliding leaf in this way, so that the risk of commuting or even jumping out of an associated guide for the sliding leaf is significantly reduced. Such a centering section is preferably formed with centering surfaces which are provided on both sides of the sliding sash.

It may also be advantageous if in a stopper device according to the invention the at least one centering centering surfaces and the associated buffer section has a buffer surface, which have an obtuse angle to one another. According to this embodiment, different areas are assigned different functions. Thus, the actual buffer effect is provided mainly or substantially exclusively by a buffer surface, which thus also defines the end stop and thus the end position for the sliding leaf. This buffer surface is accordingly provided with an elastic effect which makes it possible to provide this end stop in a cushioning manner with the buffer effect for the sliding leaf. Separately from the centering surfaces and in particular arranged on both sides of the buffer surface, the centering surfaces are now provided. These centering surfaces are not necessarily elastic, since they are aimed in particular at the centering function of the buffer body. It is of course also conceivable that the centering can provide a buffer effect by an elastic material design available. The separation of centering function and buffer function on the centering surfaces and the buffer surfaces makes it possible to provide these two functionalities in a common buffer body in a cost-effective and simple manner. In particular, this division is provided for both or all buffer sections of the buffer body. The formation of an obtuse angle between centering surfaces and buffer surfaces leads to the fact that the management functionality is particularly simple and inexpensive. Thus, the entire buffer body thus opens in a substantially funnel-shaped or trapezoidal manner, starting from the buffer surface in the sliding direction away from the buffer surface. The obtuse angle thus serves, so to speak, also for capturing a sliding wing that is already slightly oscillating in a transverse direction during its movement in the sliding direction. The obtuse angle can therefore also be referred to as a centering angle in accordance with the invention.

It is likewise advantageous if, in the case of a stopper device according to the invention, the buffer sections differ with regard to the geometric design of their centering sections, in particular that the centering surfaces and the buffer surfaces are adapted to geometries of different sliding sashes with regard to their geometric extent. As already explained, the buffer sections are specific for different purposes. Such purposes are in particular different geometries of sliding sashes. This way, sliding sashes can have different strengths have, in particular depending on the materials used. Depending on the application situation and design of the sliding door system, however, the respective sliding sash may additionally also have different distances from the wall of the building. The arrangement and geometric extension of the centering or the centering allows now to provide different geometrical overall situations for the individual buffer sections, which are adapted to different geometric requirements of the respective sliding sash. A simple transfer between the at least two buffer positions thus makes it possible to provide an otherwise impossible flexible adaptation to different geometric situations on site. In addition to the fundamental increase in flexibility, a simple and cost-effective adaptation of the buffer effect of the stopper device directly at the installation site is possible in this way.

It is also advantageous if, in a stopper device according to the invention, the centering sections of the two buffer sections have differently aligned centering planes, in particular the centering plane of the centering sections of the two buffer sections enclose an angle in the range between 80 ° and 100 °. In particular, the angle between the two buffer sections is designed for their centering planes in the range between 85 ° and 95 °. The essentially vertical adjustment of the centering planes in this way relative to one another is in particular aligned with different mounting positions of the entire stopper device. Thus, a stopper device can be mounted on the floor or on the ceiling in order to provide a corresponding buffering effect. However, if the identical stopper device is mounted on the wall, then the entire stopper device is aligned in the Essentially rotated by 90 °, since usually the wall aligns vertically with the floor and ceiling. As a result, in this embodiment of a stopper device according to the invention, the centering planes of the two buffer sections, which are aligned differently in the same way, permit a corresponding adaptation of the buffer effect to the wall mounting or, on the other hand, the ceiling or floor mounting.

A further advantage can be achieved if, in a stopper device according to the invention, at least one buffer section has at least two centering sections with differently aligned centering planes, in particular the centering planes of the at least two centering sections of the one buffer section enclose an angle in the range between 80 ° and 100 °. Also he hi he is again preferably an angle between 85 ° and 95 ° used t. As in the description of the preceding embodiment, reference may also be made here to different mounting positions of the stopper device on the floor or the ceiling on the one hand or the wall next to a door opening on the other. However, it becomes possible here for the centering function to be adapted to the different mounting situation within a single buffer section. In particular, all buffer sections have a corresponding double design of the two centering sections. This makes it possible to adapt the individual buffer sections with regard to their buffer effect, for example their degree of elasticity, or with regard to their geometric characteristics, that is, for example, their distance from the wall or with respect to the width of a sliding leaf. The specification as to the location of the assembly takes place within the respective buffer section by the provision of at least two different centering sections. This allows flexibility with regard to the use of a stopper device to increase even further.

It is a further advantage if, in the case of a stopper device according to the invention, the at least one centering section extends around a projection over a buffer surface of the associated buffer section and a centering length as a ratio of the projection to the buffer width of the buffer surface is in the range between 0.1 and 1, in particular in the range between 0.1 and 0.5. Surprisingly, it has been found that it is precisely the centering length that exerts a great influence on the mode of action or the effectiveness of the centering functionality. The found areas for the centering, in particular in the range between 0.1 and 1, are ideally geared to a reduction in the size and weight of the individual components with simultaneous substantially optimal provision of the centering function. In the case of the stopper device according to the invention, the buffer sections have a planar alignment at least in sections and enclose a buffer angle in the range between 85 ° and 95 ° with one another. This refers in particular to the buffer areas of the individual buffer sections. The surfaces, as they are defined in several places in the context of the present invention, can have essentially free surface structures or surface orientations. However, it is preferred if the respective surface is formed as a flat surface or substantially flat surface. The buffer angle between the two buffer sections influences the overall geometry of the buffer body. The buffer angle in the range between 85 ° and 95 ° results in that essentially a symmetrical design of the Buffer body is formed extending to a plane of symmetry at 45 ° angle between these two buffer sections. This improved symmetry allows a comparative double use and thus a simplified selection and arrangement of the individual mounting positions or buffer positions. The individual buffer sections or the individual side lengths of the buffer body are therefore formed the same length or substantially the same length.

It is likewise advantageous if, in the case of a stopper device according to the invention, the buffer body has a damping depth for at least one buffer section as the ratio between the body width of the buffer body and the body depth of the buffer body in the range between 0.3 and 0.9, in particular in the range between 0.4 and 0 , 7. The attenuation depth has surprisingly been found according to the invention as a parameter, which provides a strong influence on the buffer functionality of the buffer body. This makes it possible, despite reduced thickness and reduced size of the entire component of the buffer body to provide the most advantageous and high buffering available.

A further advantage can be achieved if, in a stopper device according to the invention, at least one buffer section has a function designation for specifying the function of the buffer section. A functional designation is in particular a technical function designation that contains information regarding the orientation, the mounting direction or assembly functionality and / or with regard to the intended use of this buffer section. Thus, information about the door width, the distance to the wall or the damping parameters of this buffer section can be part of such a function designation. Also dimensions or the indication of Centering length and / or the damping depth are possible in the sense of this embodiment of the present invention. Further, it is advantageous if, in a stopper device according to the invention, the mating interface has a latching device for a latching attachment to the buffer interface, in particular designed as a form-fitting engaging behind, elastic locking lug. This results in a reversible or irreversible connection between the mating interface and the buffer interface. Characterized in that the buffer body is preferably formed elastically deformable, an automatic intervention by means of the locking device can be provided accordingly by this elastic deformability. The assembly is thus facilitated as well as accelerated. The locking device is preferably formed on the inside, so that, for example, receiving slots are provided in the buffer body, which provide internally the mating interface available.

It may also be advantageous if, in the case of a stopper device according to the invention, the buffer body has side surfaces which are in particular formed perpendicularly or substantially perpendicular to the buffer sections and which are designed without function. As a result, the function of the buffer effect and / or the centering effect is substantially completely focused on the individual buffer sections. The side surfaces are kept in this way function-free, so there remains freedom for optical elements. Also, the inclusion of more information, for example using a presentation clip can be possible here.

Likewise provided by the present invention is a method for mounting a stopper device according to the present invention, comprising the following steps:

• Attaching the mounting body to a building by means of the mounting interface,
• Selecting a first buffer position or a second buffer position of a buffer body,
• Attaching the buffer body by means of the mating interface at the buffer interface in the selected buffer position.

By selecting the orientation and thus the respective buffer position, the associated buffer effect is selected accordingly. The use of a stopper device according to the invention thus brings with it the same advantages as have been explained in detail with reference to a stopper device according to the invention.

A method according to the invention can be further developed in such a way that the mounting body is movably fastened to the structure in the first step, then the buffer body is fastened to the buffer interface and aligned together with the mounting body on the sliding leaf. It is immovably attached to the structure after aligning the mounting body. The first alignment can be provided for example by this pre-assembly using a slot. It is also possible that an additional attachment or by a corresponding tightening of a screw in a slot, the immobile final attachment to the building is achieved by an additional hole.

Further advantages, features and details of the invention will become apparent from the following description in which, with reference to the drawings, embodiments of the invention in detail are described.

In the Fig. 1 to 8 An embodiment of a stopper device according to the invention and its associated arrangement will be explained in more detail. The Fig. 1 shows the combination of the stopper device 10 from a mounting body 20 on the one hand and a Buffer body 30 on the other. The mounting body 20 is in Fig. 2 shown in more detail, so that here on the one hand, the mounting interface 22 in the form of a slot and an additional hole and the buffer interface 24 can be seen in the form of two outstanding ribs.

Fig. 3 shows the associated buffer body 30, which has corresponding receiving slots, which include the mating interface 34 or provide. Here, the locking device 35 can be seen, which can engage in corresponding receiving recesses in the buffer interface 24. If the assembly of such a stopper device 10, the mounting body 20 is first attached to a corresponding structure 200, as the Fig. 8 shows. Subsequently, the installer selects an orientation of the buffer body 30, and thus, for example, under the perception of the function designations 39, selects the corresponding buffer position P1 or P2. These buffer positions P1 and P2 are in terms of their different effect, for example in the 6 and 7 to recognize. Subsequently, the installer puts the buffer body 30, so that accordingly the assembly situation according to the Fig. 1 arises.

Of the Fig. 1 It can also be seen that the two buffer sections 32a and 32b have an additional functionality, namely in each case a centering section 36 which has associated centering surfaces 36a. The centering surfaces 36a differ from the associated buffer surface 38.

In the 6 and 7 Depending on the mounting situation, the effect is displayed. For example, if the stopper device 10 is in an upper or lower mounting position such as the one shown in FIG Fig. 8 shows, so will the Sliding wing 110, which obscures a door opening 210, a sliding door 100 centered in the position and struck as the Fig. 6 shows. The stopper device 10 is in a wall mounting, as it is the middle position in the illustration according to Fig. 8 Accordingly, the sliding leaf 110 will accordingly come in a centering direction and sliding direction to the stopper device 10, as the Fig. 7 shows.

In the 4 and 5 the individual geometric correlations are shown in more detail. So is in the Fig. 4 on the one hand to detect the buffer angle α, which in this embodiment of the stopper device 10 and the buffer body 30 represents the symmetrical formation by a buffer angle α of about 90 °. It can also be seen here that a centering length ZL is made available as a ratio between the projection UB on the one hand and the buffer width PB on the other hand, like the Fig. 5 shows. In the Fig. 5 In addition, the attenuation depth DT can be recognized as a correlation between body depth KT and body width KB. It is also shown here by the top view in Fig. 5 different centering planes Z are provided, which can provide the centering effect in different orientations according to different mounting positions available.

The above explanation of the embodiments describes the present invention solely by way of example. Of course, individual features of the embodiments, if technically feasible, can be freely combined with one another without leaving the scope of the present invention as defined in the claims.
