Description

The present invention relates to a roller carriage for receiving a sliding door and a sliding door system with a roller track and at least one slidably mounted on the roller track roller carriage.

It is known that different types of doors can be used for closing doors. In particular, sliding doors are used. These sliding doors are usually provided with sliding door leaves, which are held in corresponding clamping devices of a roller carriage. In order to ensure the sliding functionality, such roller carriages are used in roller races, which in turn are mounted above the door opening on the wall and / or the ceiling. In the known solutions, therefore, a movement is performed between an open and a closed position of the sliding door. In this case, corresponding storage devices, in particular rollers, run on the roller track. During this movement, it is possible that vibrations from the roller track are registered in the roller carriage. It is also conceivable that vibrations are introduced into the roller carriage from the sliding door. Since here often a plurality of individual components is combined, and in particular the connection between the roller carriage and the roller track is formed only in einhängender way, this particular vibration can lead to noise. Thus, the structure-borne noise generated and relayed in the respective body is emitted by at least one of the bodies and in this way as an acoustic frequency by the user the sliding door system perceptible. The vibration described above can thereby reinforce within the overall system of the sliding door system and in this way further enhance the negative impression of a loud moving. The volume when moving a sliding door is often perceived by the user as one of the main criteria when it comes to assessing the quality of the sliding door system. Thus, a loudly moving sliding door in the perception of the user of the sliding door system is a poor or inferior product.

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 improve the quiet running of a roller carriage in a cost effective and simple manner.

The above object is achieved by a roller carriage with the features of claim 1 and a sliding door system with the features of claim 13. 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 roller carriage according to the invention apply, of course, also in connection with the sliding door system according to the invention 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 may be.

According to the invention, a roller carriage is provided for receiving a sliding door. This roller carriage has a roller module for slidable attachment to a roller conveyor. Next, a body is provided for attachment to the sliding door. One Roller carriage according to the invention is characterized in that the roller module is formed of a first material and the base body of a second material. In this case, the first material conducts structure-borne noise in a first sound-conducting region, and in a second sound-conducting region, this first material dampens the structure-borne noise. The second material conducts the structure-borne sound in the second sound-conducting region and in turn dampens the structure-borne noise in the first sound-conducting region.

An inventive roller carriage has in particular at least two components, namely the roller module and the main body. Of course, other components may be provided and / or these two components may be composed of individual bodies. A roller carriage is within the meaning of the present invention an overall system which fulfills at least two functions. Thus, on the one hand by the roller module, the slidable attachment to the roller track is possible. Even though the terminology of rolls is already used here, the provision of bearing devices of rolls is only one option for the embodiment of a roll carriage according to the invention. Of course, such a roller carriage for the sliding bearing also have a linear guide, for example, a sliding bearing or a linear drive. However, in view of reduced complexity and reduced costs, the formation by rotatable rollers is preferred for such a bearing device. The second function is the attachment of the sliding door. This may be, for example, a clamping attachment.

The roller module and the main body are according to the invention separate components or separate body. Each of these two components, so the roller module and / or the body can even one Have a variety of items that are interconnected. For example, the roller module may have corresponding bearing devices in the form of rotatably mounted rollers. The main body can have a plurality of individual components, such as further devices for additional functions. In addition to a height adjustment device, this can also be a securing device, a fixing device or else a clamping device by means of which the sliding door can be fastened to the basic body.

Basically, the direction of movement by means of the roller carriage is open according to the invention. Thus, here a movement along a straight line can be performed in exactly the same way as a movement along a curved or multiply curved movement line within the scope of the present invention is conceivable.

A displaceable attachment to a roller track is to be understood specifically for the respective embodiment of the storage. If, for example, bearing devices are provided in the form of individual rollers, then these rollers are inserted into a corresponding roller track. If, for example, a sliding bearing is provided, the roller module is attached to a corresponding slide rail or to a corresponding slide rail.

According to the invention, there is now a correlation of two different materials in the roller carriage. An embodiment of a first material and a second material is understood to mean that the roller module has the first material or the second material at least for the most part with respect to its acoustic effectiveness. Of course, attachments or other components may also include other materials. In particular, however, in one Section in the force path between the recorded sliding door and the roller track are the two materials, so the first material and the second material exclusively or substantially exclusively arranged.

A sound conduction region may relate, for example, to the type of sound. In the guiding function of a material, ie within a body, the sound will propagate as structure-borne sound in different directions. In particular, a distinction must be made between a longitudinal wave and a transverse wave. In this case, a sound-conducting region can define precisely one of these two orientations or propagation directions of the sound. Thus, it is conceivable that the first material has a damping property in the longitudinal wave range, while the second material includes a damping effect for transverse waves. The corresponding conductive property is also complementary. Of course, different Schallleitbereiche can also overlap.

Schallleitbereiche may additionally or alternatively also different types of sound from each other. In particular, different frequencies and / or different frequency amplitudes can be used for differentiating different sound transmission ranges.

It is crucial that, at least in small sections, the two materials are mutually mutually damping. In other words, this means that a structure-borne noise, which arises or is absorbed in the first material, is at least partially damped by the corresponding complementarily formed damping property of the second material of this second material. In reverse is a structure-borne sound, which arises in the second material or is absorbed by this, attenuated by the complementary design damping property in exactly this Schallleitbereich of the first material. In the event that the damping property is present directly in the material for the resulting type of structure-borne noise, in which the structure-borne sound is formed or absorbed, the damping takes place even within the material.

As has been explained above, the two materials act, as it were, sound-specific complementary or at least partially sound-specific complementary to each other. This means that structure-borne noise, regardless of which side it is introduced into the respective material, or structure-borne noise, no matter in which of the two materials it is formed, is superimposed by the opposite material or by the same material with a damping property. This independence of the type of sound damping is achieved, which is achieved by a specific combination of materials. Without additional damping functions or damping devices damping is provided solely by this surprisingly found material combination, which structure-borne noise within the system of the roller carriage either completely prevents the emergence or attenuates within the forwarding in the roller carriage. The prevention of structure-borne noise or the attenuation of structure-borne noise causes a user of such a sliding door system perceives the movement of the sliding door between different positions as much quieter and thus higher. In order to ensure a corresponding transmission or transmission of structure-borne noise between the individual components of a roller carriage, these are usually or advantageously associated with each other. So can be between the first material and the second material is a sound-transmitting contact. This can be provided by direct contacting of the main body with the roller module. Also sound technical transferring intermediate components are of course conceivable in the context of the present invention.

It may be advantageous if, in a roller carriage according to the invention, the roller module has a transfer section and the base body has a counter transfer section, the transfer section contacting the counter transfer section in particular flatly. This means that there is a direct contact between roller module and main body. A flat contact can be in particular a planar contact formed flat. This contacting is now used to provide a transmission of structure-borne noise between the two materials of the roller module and the body. The larger the corresponding area for such transfer, the more effectively the corresponding damping property of the complementary material can act on the associated material. The complementary damping effect according to the invention is amplified in this way, so that the function of the damping or the avoidance of structure-borne noise can be further improved in this way. The contacting is preferably formed in two or more directions, so that beyond the corresponding transmission of structure-borne noise can be provided in two or more directions. In particular, different transmission directions are perpendicular or substantially perpendicular to one another, so that the contacting section and the countertransmission section are also formed perpendicular or substantially perpendicular to one another. As a result, structure-borne sound waves directed in particular perpendicularly or substantially perpendicularly to one another through one and the same Transmission section or counter-transmission section can be transmitted. In particular, the roller module has a first surface, for example a side surface of the roller module, which preferably bears against the base body in a contact area between 80% and 100% of this surface. An enlarged in this way contact surface between these two components leads to improved sound transmission and thus to an improved damping effect according to the invention.

It is also advantageous if the base body and / or the roller module are monolithic in a roller carriage according to the invention. This is to be understood in particular as an integral or one-piece design of the respective component. In the production of significant advantages can be achieved in this way. Also can be achieved by the monolithic design of the respective component of the advantage that a uniform and thus predictable propagation of structure-borne noise is provided within the component. This additional installations or negative influences or reinforcements of the resulting or recorded structure-borne noise are still further avoided. The damping properties can be improved in this way.

• Dichte zwischen 7 kg/dm³ und 9 kg/dm³
• Schub-Modul zwischen 70 kN/mm² und 90 kN/mm²
• E-Modul zwischen 180 kN/mm² und 240 kN/mm²

According to the invention, it is further advantageous if, in a roller carriage according to the invention, the first material of the roller module has at least one of the following material parameters:

• Density between 7 kg / dm ³ and 9 kg / dm ³
• Thrust module between 70 kN / mm ² and 90 kN / mm ²
• E-modulus between 180 kN / mm ² and 240 kN / mm ²

The list above is a non-exhaustive list. In particular, the density is in the range of about 7.9 kg / dm ³ , the thrust modulus in the range of 80 kN / mm ² and the modulus of elasticity in the range of about 210 kN / mm ² . The above parameters are set even closer in relation to other parameters later, and constitute an exemplary embodiment of inventive properties of the first material with regard to their sound specificity.

• Dichte zwischen 6 kg/dm³ und 8 kg/dm³
• Schub-Modul zwischen 30 kN/mm² und 50 kN/mm²
• E-Modul zwischen 70 kN/mm² und 100 kN/mm²

It is likewise advantageous if, in a roller carriage according to the invention, the second material of the base body has at least one of the following material parameters:

• Density between 6 kg / dm ³ and 8 kg / dm ³
• Thrust modulus between 30 kN / mm ² and 50 kN / mm ²
• E-modulus between 70 kN / mm ² and 100 kN / mm ²

The list above is a non-exhaustive list. In this case, for the second material, the modulus of elasticity preferably in the range of about 85 kN / mm ² , the shear modulus in the range of 40 kN / mm ² and the density in the range of about 6.7 kg / dm ³ are. Here, too, corresponding correlations can be achieved in a particularly simple and cost-effective manner in order to provide the complementary damping characteristic according to the invention between the first and second material.

• Dichte zwischen 7 kg/dm³ und 9 kg/dm³
• Schub-Modul zwischen 70 kN/mm² und 90 kN/mm²
• E-Modul zwischen 180 kN/mm² und 240 kN/mm²

In addition, it is advantageous if, in a roller carriage according to the invention, the base body has a glass clamp with at least one of the following material parameters:

• Density between 7 kg / dm ³ and 9 kg / dm ³
• Thrust modulus between 70 kN / mm ² and 90 kN / mm ²
• E-modulus between 180 kN / mm ² and 240 kN / mm ²

The list above is a non-exhaustive list. In particular, the first material of the roller module is used for the glass clamp. For example, the glass clamp may have an E-modulus in the range of about 210 kN / mm ² , a thrust modulus in the range of 80 kN / mm ^2, and a density in the range of about 7.9 kg / dm ³ . Here, too, corresponding correlations are shown later, which can lead to the inventive design of the damping material effect. In particular, reference is made to the multiplication of the attenuation, if not only a first material pairing between the first and second material is provided, but a concatenation of three or more material pairings. It is particularly important to pay attention to an alternating formation of the different materials, so that, for example, components are strung together as follows: component 1 with the first material, component 2 with second material and component 3 with third material. The corresponding contacting row accordingly provides component 1 to component 2 and component 2 to component 3. Thus, the damping effect can be amplified, so to speak, as a damping cascade or damping chain. In particular, such a cascade is formed along the force path as a roller track, roller module, base body and glass clamp. In particular, the following combination options are conceivable as a cascade for the individual components: COMPONENT 1 COMPONENT 2 COMPONENT 3 COMPONENT 4 Roller track roller module body glass clamp roller module body glass clamp -.- Roller track roller module body -.-

It is also advantageous if, in a roller carriage according to the invention, the base body has a U-shaped glass clamp for a clamping attachment of the sliding door. This may in particular be the glass clamp according to the preceding paragraph. A U-shaped design, in particular in the form of two U-shaped glass clamps, which are arranged at both ends of the base body, allows a particularly simple and inexpensive mounting option for the sliding door. The respective glass clamp thus also serves to absorb structure-borne noise from the sliding door, which is picked up from there and forwarded or created in the sliding door. When mounting by means of a correspondingly U-shaped glass clamp can occur, for example, a deformation of this U-shaped glass clamp. However, it is preferred if this U-shaped glass clamp has at least one displaceable clamping plate which can enlarge or reduce a gap within the opened U. This can be applied to the sliding door by reducing the corresponding gap, the clamping force and thus the clamping action. The glass clamp is formed in particular with a material, as has been explained in the preceding paragraph. The glass clamp can rest against the base body, in particular flat, for improved transmission of the sound between these two components. Also, a partial or complete encompassing of the body by the glass clamp in the context of the present invention is conceivable.

It is also advantageous if, in a roller carriage according to the invention, the roller module with the main body frictionally, positively and / or frictionally connected, in particular by means of fastening screws. A frictional connection, a form fit and / or a frictional connection serves in particular to provide the corresponding transmission possibility of structure-borne sound. Only this transmission possibility makes it possible, as it were, to exchange the damping properties between the two materials in a complementary manner and to make them available to the respectively adjacent material. Of course, two or more different types of compounds combined with each other in the context of the present invention can be used.

A further advantage may be when, in a roller carriage according to the invention, the roller module has a bearing device with at least one, in particular at least two rotatable rollers. In principle, any shape of the bearing device can be used, that is also a sliding bearing or even a linear drive with a corresponding plain bearing. In order to further promote the reduction of the formation of structure-borne noise, however, an embodiment of the bearing device with at least one roller is advantageous. This can be achieved by a variation of sliding friction on rolling friction a significant reduction of vibration. The formation of structure-borne noise is thereby already reduced before the occurrence of the damping effect according to the invention. Preferably, the individual rollers are ball-bearing and have on their surface a reduced roughness.

• Dichte zwischen 1 kg/dm³ und 2 kg/dm³
• Schub-Modul zwischen 2 kN/mm² und 6 kN/mm²
• E-Modul zwischen 2 kN/mm² und 3 kN/mm²

A further advantage may be obtained if, in the case of a roller carriage according to the invention, this roller is formed of at least one plastic roller, in particular with one of the following material parameters:

• Density between 1 kg / dm ³ and 2 kg / dm ³
• Thrust modulus between 2 kN / mm ² and 6 kN / mm ²
• Modulus of elasticity between 2 kN / mm ² and 3 kN / mm ²

The list above is a non-exhaustive list. The modulus of elasticity is preferably in the range of about 2.6 kN / mm ² , the shear modulus in the range of about 4 kN / mm ^2, and the density preferably in the range of about 1.4 kg / dm ³ ,

It is likewise advantageous if, in a roller module according to the invention, the modulus of elasticity of the first material to the modulus of elasticity of the second material is between 1.5: 1 and 2.5: 1 and / or the shear modulus of the first material is Module of the second material between 2.5: 1 and 3.5: 1 is formed. In the following, a longer list of possible correlations or ratios is given, which can likewise be effective according to the invention. In particular, the same or an improved effect can also be possible with a corresponding reversal of the materials. The stronger material in terms of the functionality of the modulus of elasticity and / or the thrust module is used for the mechanically higher loaded component. In particular, the corresponding ratios are combined, as will be explained below. In addition, a sound-specific density for the respective material can be defined. A sound-specific density is to be understood as meaning that the material density is multiplied by the quotient of the modulus of elasticity divided by the shear modulus [density x (modulus of elasticity / shear modulus)]. This results in this sound-specific density for the first material, a range of about 10 kg / dm ³ to about 30 kg / dm ³ and a similar range of values for the second material. Thus, in the selection of the two materials, in particular, there are three basic possibilities. Thus, it is conceivable to form both materials within one or more value ranges of the individual parameters and to pay attention to the proviso of the inventive complementary damping. Furthermore, it is conceivable to generate the complementary damping on the basis of the listed parameter ratios. Another possibility is the selection of at least one parameter for one of the two materials, wherein subsequently the corresponding parameter for the second material results from the stated ratios. Decisive are the ratios described in the following list, in which the sound-specific density between the individual components is. Below is detailed for the modulus of elasticity, shear modulus, density and sound specific density, which ratio ranges can provide the specific effect here in the sense of the present invention.

Thrust module:

• Roller module: basic body = 2.5: 1 to 3.5: 1
• Body: Glass clamp = 1: 2.5 to 1: 3.5
• Roller module: Base body: Glass terminal:
  • 2.5: 1: 2.5 to 2.5: 1: 3.5
  • 3.5: 1: 2.5 to 3.5: 1: 3.5

Modulus of elasticity:

• Roller module: Base = 1.5: 1 to 2.5: 1
• Body: Glass clamp = 1: 1.5 to 1: 2.5
• Roller module: Base body: Glass terminal:
  • 1.5: 1: 1.5 to 1.5: 1: 2.5
  • 2.5: 1: 1.5 to 2.5: 1: 2.5

Density:

• Roller module: Base = 1: 1.5 to 1.5: 1
• Body: Glass clamp = 1.5: 1 to 1: 1.5
• Roller module: Base body: Glass terminal:
  • 1: 1.5: 1 to 1: 1: 1
  • 1.5: 1: 1.5 to 1: 1: 1

Sound specific density:

• Roller module: basic body = 1: 0.5 to 1: 1.7
• Body: Glass clamp = 0.5: 1 to 1.7: 1
• Roller module: Base body: Glass terminal:
  • 1: 0.5: 1 to 1: 1.7: 1
  • 0.5: 1: 0.5 to 1.7: 1: 1.7

These value ranges or ratios are explicitly solutions that meet the damping and line properties defined according to claim 1 of the present application. A material combination which lies within the following ratio ranges, is accordingly in the context of the present invention, a material pairing according to claim 1 of the present application.

Further, it may be advantageous if, in a roller carriage according to the invention, each material has a sound-specific density which results from the material density multiplied by the quotient of the modulus of elasticity divided by the shear modulus of the respective material, wherein the sound-specific density of the first material to the sound-specific density of the second material in the range between 1: 0.5 and 1: 1.7 is formed. This is a particularly advantageous Correlation for achieving the complementary damping effect according to the invention. Thus, this attenuation function is provided in this way, preferably independent of the type and direction of a sound.

Another object of the present invention is a sliding door system, comprising a roller track and at least one slidably mounted in the roller track roller carriage according to the present invention. Of course, two roller carriage can be provided in which a sliding door is already attached. This brings a sliding door system according to the invention with the same advantages, as they have been explained in detail with respect to a roller carriage according to the invention.

Dabei handelt es sich zum einen um das Rollenmodul 20 und zum anderen um den Grundkörper 30. Beide Bauteile, also Rollenmodul 20 und Grundkörper 30 weisen dabei eine Vielzahl unterschiedlicher Einzelteile auf. Diese Einzelteile werden im Nachfolgenden kurz erläutert.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 are described in detail. The features mentioned in the claims and in the description may each be essential to the invention individually or in any desired combination. It show schematically.

In Fig. 1 an embodiment of a roller carriage 10 is shown in isometric view. This has two basic components. These are, on the one hand, the roller module 20 and, on the other hand, the main body 30. Both components, that is to say the roller module 20 and the base body 30, have a multiplicity of different individual parts. These items are briefly explained below.

The roller module 20 is here equipped with a bearing device 26. This bearing device 26 is here equipped in the form of two rollers 26 a, which are rotatably mounted on a base body of the roller module 20. These rollers 26a can now be used on or in a roller track 120, as in the Fig. 2 and the Fig. 3 easy to recognize. Further, part of a height adjustment device 70 is provided on the roller module 20. The detailed components of this height adjustment device 70 are in particular in the 4 and 5 shown. Thus, a first adjusting means 32 is provided here, which can perform an adjusting movement by means of a handling interface 36. Since here the first adjusting means 36 is formed as a threaded screw in an adjusting thread 32a, takes place at the handling interface 36, a rotational movement, which simultaneously generates a linear translational movement of the first adjusting means 32. Via a corresponding contact section 34, the first adjusting means 32 is in operative connection with a mating contact section 24 of the second adjusting means 22 of the roller module 20. The explicit effect of this adjusting device is to convert the adjusting movement into an adjusting movement along the direction of gravity SKR.

Like from the Fig. 1 can be seen, the roller carriage 10 is equipped with a plurality of different mounting devices 90, which can provide different mounting functions. The adjustment function of the height of the sliding door 110 already described is provided by the mounting device 90 in the form of the height adjustment device 70. Next, a mounting device 90 is provided in the form of a securing device 50, which after the adjustment of the height of the sliding door 110 provides a clamping fixation between the base body 30 and roller module 20.

Another mounting device 90 here is an accessory device 40 which is provided by a corresponding interface and attached accessory module 300. In addition, a Aushebeschutzvorrichtung 60 is provided as a mounting device 90, which provides a Aushebeschutz against unwanted leaving the roller carriage 10 of the inserted in the roller raceway 120 position. Further, a fixing device 80 is provided as a glass clamp for a mounting device 90 to fix the sliding door 110 in a clamping manner.

All mounting devices have in common that they have at least one mounting means 92 in order to perform a corresponding assembly movement can. In addition, a handling interface is provided in order to perform precisely this assembly movement with the mounting means also.

Again Fig. 1 moreover, the roller carriage 10 has different sides, namely the first side 12 and the second side 14. All mounting devices are preferably of the same side, namely the first side 12 opposite to the second side 14, with respect to their handling interface 96. on which the bearing device 26 is arranged aligned. This allows a much easier access.

In Fig. 2 is shown as a sliding door 110 of two roller carriage 10 according to the Fig. 1 is held and these two roller carriage 10 are already used in the roller track 120. In a side view according to Fig. 3 In particular, the correlation of the rollers 26a with the roller track 120 can be clearly seen.

In Fig. 6 It is easy to see how basically two components can be distinguished from each other. These are, on the one hand, the roller module 20 and, on the other hand, the base body 30. On the roller module 20, rollers 26a of the bearing device 26 can be seen here, which are formed here from plastic. Also, on the back of the transmission sections 21 can be seen, which can come into surface contact with corresponding Gegenübertragungsabschnitten 31 of the main body 30. The main body also has two U-shaped glass clamps 39, in which the sliding door 110 can be arranged in clamping attachment.

If the two components of the main body 30 and the roller module 20 are fastened to one another, the result is a combination of materials according to the invention. The two materials, that is, the first material of the roller module 20 and the second material of the main body 30 in this case have a sound technical property, as they abstract the Fig. 7 reproduces. On the y-axis, the corresponding conductivity of structure-borne noise is shown, while on the x-axis a corresponding distinction is made in different orientations or types of structure-borne noise. Thus, for example, the angle of the orientation of the structure-borne noise can be plotted on the x-axis. Also, a frequency spectrum or an amplitude spectrum may be plotted on the x-axis. Here it is easy to see that two fundamental sound conduction regions I and II can be distinguished from one another. The corresponding self-adjusting curves for the first material and the second material, that is to say for the roller module 20 and the main body 30, are here designed to be complementary or essentially complementary. If a corresponding structure-borne noise arises in the sound-conducting region 1 from this sound-conducting region 1 in the roll module 20 or is picked up by the latter, then this structure-borne noise which has been produced or recorded is forwarded. About the transmission section 21 and the countertransference section 31, a transition of this structure-borne noise on the base body 30. The body is, however, in exactly this Schallleitbereich I equipped with a very poor sound conduction and thus with a damping property. The structure-borne sound is now in the second material of the base body 30 only very slowly or not at all redistribute and damped in this way in terms of its amplitude. The total amount of sound emitted by the system of the roller carriage is reduced in this way. Consequently show the Fig. 6 and 7 very clearly, in which way the complementary damping properties of the two different materials of roller module 20 and body 30 provide the damping effect system-internally 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 combined freely with one another, without departing from the scope of the present invention.
