Description

The invention relates to a carriage according to the preamble of claim 1, a carriage assembly according to the preamble of claim 19, a building hardware according to the preamble of claim 20, and the use of the carriage according to the invention.

In many modern buildings, to meet functional requirements, increasingly a movable, in particular displaceable, arrangement of components, e.g. Sliding windows, sliding gates, facade elements, light protection elements, etc. required against fixed building parts. The building hardware used in this case must be able to reliably carry high loads on the one hand and at the same time oppose the sliding movements as little resistance as possible, so running as smoothly as possible.

An area in which a displaceable mounting of components has been in use for a long time, for example, are roller doors that are linearly displaceable along fixed to stationary building parts rails. For this purpose, the roller doors are attached to carriages, which are easily movable with rollers in the stationary rails. The load direction is in this application mainly vertically downwards; for removing horizontal load shares in the building, on the carriage in addition to the rollers with horizontal axis of rotation rollers are added with a vertical axis of rotation, which are guided on substantially vertical guide surfaces of the guide rail. In order to prevent the introduction of torques into the carriage assembly by eccentric with respect to the track, e.g. To avoid horizontally acting load components, an additional guide arrangement for receiving horizontal load shares is provided in many cases at the lower edge of roller doors.

In addition to this simple load case in which the carriages are loaded essentially only vertically downwards, there are also applications in which the carriages must initiate loads both vertically downwards and vertically upwards into the track rail. This is the case, for example, in cantilevered sliding doors, where the rear trolley in the extended state of the sliding gate must initiate considerable loads vertically upwards in a guide rail, while with retracted sliding door of the rear carriage, as well as the front carriage, a vertical load down has to transfer.

The carriages, which are suitable for load transfer in different directions, are mostly made from combinations of conventional carriages, or designed as elaborate special constructions. These carriages are therefore correspondingly heavy and large building or expensive to purchase and difficult to obtain.

A known embodiment of a carriage of accordion doors is in document DE 203 03 232 U1 described.

The object of the invention is therefore to provide a carriage or a building hardware for displaceable arrangement of a device that is simple in construction, but nevertheless for different applications or load cases and consequent different load directions can be used.

This object of the invention is achieved by a carriage having the features of the characterizing part of claim 1. Notwithstanding the prior art, the rollers of a roller carrier are not arranged axisymmetric in this carriage, but with a uniform direction of rotation, based on the displacement axis of the carriage. The basic load which this embodiment of a roller carrier is able to absorb is a torque, e.g. by an eccentric load attack, while in previously known, simple roller carriers each starting from a centric load attack.

In the simplest embodiment of a roller carrier of the carriage according to the invention this has only two rollers which are supported on the running rail and form a counter-moment or supporting moment to a load torque introduced via the support element by the support forces acting in the same direction around the displacement axis in the direction of the radius vectors. While in the prior art is always assumed that a central load attack and for possibly occurring load moments additional casters are arranged in the carriage according to the invention by an eccentric load attack, i. a load torque, as a base load, which can be transmitted from a roller carrier according to the preamble of claim 1 in the track, wherein by the inventive arrangement of at least one roller carrier with respect to the remaining roller carriers opposite sense of rotation of the radius vectors of the rollers with respect to the longitudinal axis and forces and load moments can be recorded in additional directions.

In order to accommodate loads and load moments in additional directions, it is provided in that a carriage comprises several, ie at least two roller carriers with counter-rotating circulation directions arranged one behind the other in the direction of the longitudinal central axis, which are connected to one another in a rotationally fixed manner. This roller carrier with opposite sense of rotation of the radius vectors can remove a load moment in the opposite direction in the track, whereby this combination covers a wide range of applications.

The carriage can be modularly composed of several, in the direction of the longitudinal central axis successively arranged roller carriers. Although the roller carriers can also be integrally connected to each other, a modular construction is advantageous because a carriage can be assembled according to the expected load cases optimally and with little effort from standardized components. Preferably, releasable fasteners are used, such as e.g. Screws.

A particularly stable design of the carriage is obtained when the carriage comprises three successively arranged roller carrier, wherein the radius vectors of the middle roller carrier are oriented in opposite directions to the radius vectors of the two outer roller carriers. The carriage can thereby have a plane perpendicular to the longitudinal central axis of symmetry and thereby provides a symmetrical stable load introduction into the track. By virtue of this arrangement, it is also possible to absorb load moments with torque vector oriented transversely to the displacement axis of the carriage, for example when the center of gravity of the component to be supported is located in front of or behind the carriage in the displacement direction.

The design of the rollers is not limited to cylindrical designs in the context of this invention, but rather the rollers can be formed by any rolling elements, e.g. also by balls, barrel-shaped or cone-shaped rolling elements. The rollers described in the following embodiments may e.g. also be designed as ball rollers. Also, a physical rotary axis is not required, such as e.g. in a roller bearing ball.

An advantageous development of the carriage is that the axes of rotation on the roller carrier viewed in the direction of the longitudinal central axis are arranged rotationally symmetrical. This results in simple cross-sectional shapes for the roller carrier, which may for example have a simple rectangular cross-section.

It is furthermore advantageous if a distance of roller center planes of the rollers from the longitudinal central axis corresponds to at least twice, in particular more than four times, one half of a roller width. Two diametrically arranged with respect to the displacement axis rollers thus cause the largest possible supporting moment and are therefore also suitable for receiving larger load moments, since the forces acting on the rollers supporting forces by the extended lever arms turn out smaller.

Another measure for increasing the tolerable load moments is that the rollers or their roller center planes are largely arranged in the region of inner corners of a runner leading track.

An embodiment of the carriage is that the roller carrier has four rollers with mutually perpendicular axes of rotation. By this embodiment, a hollow box-shaped track with four mutually perpendicular inner raceways can be used, which are easily available in many embodiments. Furthermore, the area around the longitudinal central axis of the roller carrier can thereby remain free for fastening means of the rotary axes and for fastening drive means.

In particular, with a square arrangement of the axes of rotation about the longitudinal central axis, the required supporting forces are better distributed to the individual rollers, as e.g. when arranging the rollers at the corners of an elongated rectangle.

Another advantage is a development of the carriage in which the axes of rotation of the rollers of a roller carrier are arranged in a common, perpendicular to the longitudinal central axis axis plane. The supporting forces of the individual rollers acting in a common plane do not cause reaction moments on the carriage.

A short length of the carriage can be achieved that a length of a roller carrier is made only slightly larger than a roller diameter. This is particularly advantageous if a plurality of carriages are mounted on a running rail, and they are to be placed next to each other in a parking position with the smallest possible pitch.

A simple design of the carriage is achieved when all wheels of a carriage are identical. In addition, this facilitates the rotationally symmetrical design of the roller carrier, whereby the combination with other roller carriers is facilitated and individual roller carriers can be easily installed with oppositely oriented radius vectors.

An advantageous for certain applications training of the carriage is that a longitudinal center plane offset by the support element with respect to a longitudinal center plane of the roller carrier and the carriage runs. As a result, the distribution of the support forces to be transmitted by the individual rollers can be substantially influenced; e.g. adapted to the strength properties of the track.

A wide possibility of influencing the load introduction into the carriage is that a support element projecting transversely to the direction of displacement of the carriage is arranged on the carrier element or on the roller carrier. As a result, a required in many applications offset between the level of the track rail and load action level is achieved, this eccentric load introduction into the carriage and thereby caused load torque is easily possible by the inventive design of the carriage.

A relation to the longitudinal median plane of the carriage staggered arranged load-receiving means on the bracket element, a pivotable about a pivot axis parallel to the running rail load-carrying means on the console element and a load-receiving means in the form of a pin or a plug-in sleeve for mounting the device form according to three further claims advantageous developments of the carriage.

The roller carrier may consist of a light metal, in particular aluminum or an aluminum alloy. By this feature, the weight of the carriage is opposite to a design, e.g. With steel roller supports, significantly reduced, whereby the forces to be absorbed by the running rail or the building can also be reduced.

The rollers can be made of stainless steel, in particular stainless steel, which ensures a long life of the carriage, especially under harsh operating conditions, for example, when used outdoors.

To reduce the operating noise when operating the carriage, it is advantageous if at least a part of the rollers has a running surface made of a plastic or an elastomer. As a result, on the one hand a noise emission is reduced in contact between the roller and track rail, and on the other hand reduces a sound transmission from the device into the building.

In addition to a passive use of the carriage, it may be advantageous if the carriage or roller carrier has a connecting element for connection to a drive device. As a result, the component can be actively moved and positioned by the carriage.

The carriage or roller carrier can be operatively connected to a linear drive. In addition to the linear guide of the component (s) effected by the carriage guided in the running track, the carriage or the roller carrier can in turn be connected to a linear drive which can bring about the positioning as well as the fixing of the carriage or roller carrier.

One possible embodiment of a linear drive may be that the carriage or the roller carrier has a guide thread for receiving a driven threaded spindle arranged in the displacement direction of the carriage. The guide thread can be formed directly from the roller carrier, but also by an additional, attached to or in the carriage or roller carrier threaded element, e.g. be formed a threaded nut. The adjustment of a carriage by means of a threaded spindle drive can be used on the one hand to achieve large actuating forces, on the other hand cause by a self-locking design of the threaded spindle reliable fixation of the carriage in the respective position.

The object of the invention is also achieved by a carriage arrangement which has at least three carriages connected to the component, which each have at least one roller carrier which corresponds to a roller carrier of the carriage according to the invention according to claim 1 and at least one roller carrier, in particular the roller carrier of the middle carriage, With respect to the remaining roller carriers opposite direction of rotation of the radius vectors with respect to the longitudinal center axis of the carriage or has. Thereby For example, the same effect can be achieved with various load input directions and load moment directions as with the carriage of claim 1. The rotationally fixed connection between the roller carriers is produced in this case via the component.

The object of the invention is further solved by a building hardware comprising a hollow box-shaped running rail and a carriage guided therein for displaceable arrangement of a component or in a building in which the carriage is designed according to the invention. The special structure of the carriage allows to adapt the hardware fitting to the load cases to be considered in each case, in particular by training the carriage for the introduction of load moments and shear forces in any direction in the track. This is particularly advantageous in the displaceable arrangement of components in outdoor use, since the wind loads occurring can occur in all directions and the removal of these loads is accomplished in the building by the inventive, simple design and inexpensive carriage.

The running rail may consist of a light metal, in particular of aluminum or an aluminum alloy, whereby a weight-saving design of the building fence is possible, allowing greater freedom of construction in the situation of the building fence and the building elements. However, stainless steel can also be used as a material for the track rail for high loads due to the components, which has a long service life even in rough outdoor use without costly maintenance.

The invention will be explained in more detail below with reference to the embodiments illustrated in the drawings.

Fig. 1 shows a view of a carriage 1 in a running rail 2, wherein this in Fig. 1 only partially shown. The view takes place in the direction of displacement 3, in which the carriage 1 in the running rail 2 is adjustable. The carriage 1 comprises a roller carrier 4, are rotatably mounted on the rollers 5. The rollers 5 are connected by means of axle 6 with the roller carrier 4 and move when moving the Trolley 1 in the running rail 2 rotatory about axes of rotation 7, which in the exemplary embodiment in each case extend concentrically to the axle elements 6. The bearing of the rollers 5 on the roller carrier 4 can be done with all types of bearings, ie, for example, by rolling bearings or plain bearings, with a rolling bearing equipment usually results in lower rolling resistance. The rollers 5 are preferably made circular cylindrical, but deviating from it are also differently shaped rolling elements possible, for example, conical, barrel-shaped or spherical rollers. The rollers 5 each contact a running surface 8, which is formed from the inside of the running rail 2, considered simplified in a roller support point 9, precisely considered by minimal deformations of the rollers 5 and the rolling elements at the contact points not exactly punctiform but flat flattened , Apart from asymmetrical embodiments of the rollers 5, passes through these roller support points 9 each one to the rotation axis 7 perpendicular roller center plane 10. In the roller center plane 10 is in each case a radius vector 11, which extends from the roller support point 9 to the axis of rotation 7.

It should be noted that the tread 8 may be flat or curved, so as to positively affect the balance of power, for example, to reduce the friction.

On the roller carrier 4, a support element 12 is further arranged, which forms the connection between the carriage 1 and a component 13, which is supported by the carriage 1.

It is now essential to the invention how a load 14, which is exerted by the component 13 and is represented by an arrow, is transmitted via the carriage 1 into the running rail 2. The illustrated embodiment of the carriage is, ignoring frictional effects, substantially adapted to transfer a vertical load 14 into the track rail 2. The in the Fig. 1 vertically downwardly facing load 14 is compensated by a vertically upwardly acting support force 15, which is represented by the vertically upwardly pointing radius vector 11. In addition, the vertically downwardly acting load 14 causes a torque with respect to a direction of displacement 3 extending longitudinal central axis 16. This torque is represented by an arrow as a load torque 17 and would rotate a freely cut carriage 1 in a clockwise direction. To produce the equilibrium, the load moment 17 must be compensated by a support moment 18 - represented by an arrow. This support torque 18 is by the vertically upward acting first support force 15 in Combined with a second support roller vertically acting down on the second roller 2 second support force 19, which points in the direction of the second radius vector 11 vertically downwards causes.

According to the invention, the radius vectors 11 of all rollers 5 of a roller carrier 4 have the same direction of rotation with respect to the longitudinal central axis 16 and thus contribute to the formation of the supporting torque 18. In more than two rollers 5 is strictly speaking a statically indeterminate system and the distribution of support forces on the individual rollers is also dependent on deformations of the claimed components, ie the rollers 5, the running rail 2, the roller carrier 4, etc. further come in In this context, geometric deviations of the components to bear, in general, these influences are only a small effect on the mode of action with sufficiently fixed dimensions and conventional manufacturing tolerances.

The middle planes 10 of the rollers 5 each have a distance 20 or 21 from the longitudinal central axis 16 and the radius vectors 11 of all rollers 5 the same sense of rotation with respect to the longitudinal central axis.

Fig. 2 shows a further embodiment of a carriage 1 in a running rail 2. At the roller carrier 4 four rollers 5 are arranged rotationally symmetrical with respect to the longitudinal central axis 16 here. The four axes of rotation 7 are therefore perpendicular to each other and rewrite in the direction of the longitudinal central axis 16 considered a square. The rollers 5 are evenly distributed in this embodiment of the carriage 1 over the circumference of the roller carrier 4, which is opposite to the embodiment in Fig. 1 with only two rollers 5, the possibility of a more even distribution of support forces results. As can easily be seen, the direction of rotation of the radius vectors 11 is again in the same direction with respect to the longitudinal central axis 16, whereby the direction of rotation of acting on the carriage 1 support torque 18 and thus the direction of rotation of a recordable load torque 19 is fixed. Due to the two additional rollers 5 with horizontal roller center plane 10, this embodiment of the carriage 1 can also accommodate loads 14 with horizontal proportions. The load torque 19 counteracts the direction of rotation of the radius vectors 11, so that the rollers 5 do not lift off in the roller support points 9 from the inside of the running rail 2.

The connection between the roller carrier 4 and the component to be supported 13 comprises the support element 12, further a separate bracket element 22, on which a fastening element 23 is arranged. The fastening element 23 may be connected rigidly, in particular in one piece, to the bracket element 22 as well as to the support element 12, but in the exemplary embodiment it is adjustable by means of a pivot bearing 24 about a horizontal axis relative to the bracket element 22. The connection between the component 13 and the fastening element 23 is designed in the form of a bushing with pins guided therein, whereby this connection in the form of a hinge is also articulated.

As already mentioned, embodiments are according to Fig. 1 and Fig. 2 essentially adapted to receive load moments and initiate them in the running rail 2, which is why the introduction of the load 14 in the carriage 4 by means of a cantilevered support member 12 and an additional bracket member 22 takes place. The line of action of the load 14 thus has a large distance from the longitudinal central axis 16, whereby the load torque 19 comes to the fore in relation to transverse forces.

Fig. 3 shows an embodiment of the carriage 1 in a perspective view in which by arranging three roller carriers 4 in a row in the direction of the longitudinal central axis 16 of the carriage 1 is designed so that even pure lateral forces without resulting load torque 18, ie the line of action of the load 14 extends through the longitudinal central axis 16, can be recorded. This is achieved by the central roller carrier 4 is turned by 180 ° about a transverse axis 25, whereby the sense of rotation of the radius vectors 11 of the middle roller carrier 4 in opposite directions to the sense of rotation of the radius vectors 11 of the two outer roller carrier 4 with respect to the longitudinal central axis 16. The direction of rotation of the radius vectors 11 of the middle roller carrier 4 is in Fig. 3 indicated by arrow 26, whereas the direction of rotation of the radius vectors 11 of the two outer roller carrier 4 is characterized by an arrow 27 runs in opposite directions. This embodiment of the carriage 1 can thus absorb load moments in both directions of rotation with respect to the longitudinal central axis 16 and is therefore also suitable for receiving centric loads. This can also be seen, for example, in that the roller bearing points 9 bearing against an imaginary upper inner surface of the track rail 1 form a triangle, whereby a stable three-point support of the carriage 1 with respect to the track rail 1 in the direction vertical upward. Likewise, by this particular rotationally symmetrical arrangement of the rollers 5 also on the other inner surfaces of a running rail 1 formed by the roller support points 9 such triangles, whereby the carriage 1 can also accommodate centric loads 14 in all radial directions. On each inner surface of a running rail 2, a support base 28 is formed by this special arrangement of the rollers 5 and the thus defined roller support points 9, which has the shape of a triangle in this embodiment. By adding a further, fourth roller carrier 4 with the same direction of rotation of the radius vectors 11 as the middle roller carrier 4, the support base would each have the shape of a parallelogram, which would correspond to a four-point support.

In Fig. 3a is schematically illustrated the arrangement of the four support bases 28 in the form of four triangles each formed by three Rollenauflagepunkte 9.

The cross-sectional shape of the running rail 2 (see Fig. 2 ) corresponds to a hollow box profile having a recess 29 through which the component 13 receiving support member 12 is guided to the outside. Advantageously, the track profile is rectangular, in particular square and has four inner raceways on which the rollers 5 are supported. Deviating from this, as in Fig. 2a However, also illustrated rail cross-sections in triangular or other, multi-sided prismatic cross sections possible, it should be kept in mind that with increasing number of side surfaces, the cross-sectional profile closer and closer to a circular ring cross-section, apart from friction effects, is not suitable for receiving load moments. The inside of the running rail 2 forms several inner running surfaces 30, on which the rollers 5 are supported. These are distributed virtually on the circumference of the roller carrier 4 and also form support surfaces for supporting the rollers 5. Two circumferentially adjacent inner raceways 30 each include an angle 31 to each other, whereby the cross-sectional shape of a running rail 2 can also be defined. As in Fig. 2a shown schematically, the angle 31 may be formed in many ways. It is possible that all angles 31 between adjacent inner running surfaces 30 of a running rail 2 have the same size, for example 90 ° for a rectangular profile cross section, 60 ° for a triangular cross section or 120 ° for a hexagonal cross section; however, the angles 31 can also assume different sizes within a track profile, for example in the case of a running track 2 with a cross section in the form of a parallelogram. It is obvious to the person skilled in the art that, in accordance with the multiplicity of possible cross-sectional shapes of a running rail 2, a correspondingly great diversity for the arrangement the rollers 5 on a roller carrier 4 is possible and the invention should not be limited to the illustrated cross-sectional shapes should be understood. However, it is advantageous for the embodiment if an angle 31 measured between adjacent inner running surfaces has a value selected from a range with a lower limit of 60 ° and an upper limit of 120 °.

Fig. 4 and Fig. 5 show a use example of the carriage 1 according to the invention, which is used together with the running rail 2 as a building hardware. In the illustrated example of application, the building hardware is used to vertical blinds 32, which are hinged together to adjust from a starting position with accordion-like folded anti-glare panels 32 in a working position with flat-spreading anti-glare panels 32.

This arrangement is used for example to protect windows on large facades by shading from excessive sunlight. The anti-dazzle fins 32 are formed for example by a perforated plate, whereby the passage of light can be reduced to a certain extent. To stiffen the anti-glare panels 32, these have an angled cross-section, whereby their bending moment is increased and the deflection due to wind loads can be reduced compared to a flat design. In each case two anti-glare blades 32 are connected by a hinge 33, for example in the form of a hinge. This formed from the individual anti-glare panels 32 slat curtain is slidably mounted on the building, not shown, by means of two rails 2 and several guided therein carriage 1. Die Lamellenvorhang ist in Fig. 1 dargestellt. Like at the same time in Fig. 5 Recognizable, every second joint 33 is hinged to the fastening element 23 of a carriage 1. In order to adjust the anti-dazzle blades 32 from the folded rest position to the working position, the first anti-glare lamella 32 is fixed to a fixed bearing 34 relative to the building, while the last anti-glare lamella 32 is connected to a driven first carriage 35. By increasing the distance of this carriage 35 to the fixed bearing 34, the anti-glare blades 32 are folded apart and pulled into the working position, with the remaining middle anti-glare blades 32 are supported by the free-running carriage 1. The driven first carriage 35 is operatively connected by means of a connecting element with a drive device 36, which in the illustrated example of use by a drive motor 37, two angle gear 38 and two the angle gear 38 with comprises the respective first carriage 35 connecting threaded spindles 39. The threaded spindles 39 each cooperate with a guide thread, not shown, on the first carriage 35 and form a linear drive for adjusting the slatted curtain. Due to the self-locking between threaded spindle 39 and guide thread, the slat curtain is reliably fixed after stopping the threaded spindle 39 in the direction 3, ie even with loads in the axial direction, for example by wind loads on the anti-glare panels 32, an unintentional adjustment of the slat curtain is prevented. The inventive design of the carriage 1 and the discharge of all radially acting on the rails 2 loads, in particular by the weight of the anti-glare panels 32, guaranteed by wind load or other forces occurring. Due to the special arrangement of the rollers 5 on the roller carriers 4 and the carriage 1, a tilting of the carriage 1 in the running rail 2 is prevented. The forces acting on the carriage 1 during the fanning out or collapsing of the anti-dazzle blades 32 in the axial direction, but eccentrically, are removed into the running rail 2 by the roller support points 9 distributed to the carriage 1.

In Fig. 1 Furthermore, it can be seen that the distance 20 or 21 of the roller center planes 10 from the longitudinal central axis 16 becomes greater with maximum utilization of a predetermined inner width of the track rail 2, if a roller width 40 is selected to be as small as possible, whereby the distance of the roller bearing points 9 from the longitudinal central axis 16 increases.

Fig. 5 It can be seen further that a length 41 of a roller carrier 4 is only slightly larger than a diameter 42 of the rollers 5, whereby the composite of several roller carriers 4 carriage 1 has a short overall length.

Fig. 2 shows that a longitudinal center plane 43 of the support member 12 may be offset relative to the longitudinal central axis 16, whereby an eccentric introduction of the load 14 is given in the carriage 1 in most of the load cases.

Fig. 6 1 shows a plan view of the use of the carriage 1 for the pivotable mounting of a component 13 in the form of a facade element 44, in particular a glass facade element 45 on a horizontal running rail 2 connected to a building. The strip-shaped glass facade element 45 is for example part of a non-illustrated, clam-shell glass facade and can be spent for ventilation purposes from a closed, the running rail 2 approximately parallel position in a running rail 2 approximately rectangular position. In Fig. 6 in dashed lines the closed position 46 and the open position 47 are indicated. The pivotable mounting of the glass facade element 45 takes place to such an extent that a pivot point 48 arranged in the region of a vertical longitudinal edge of the glass facade element 45 is connected to the carriage 1 which is adjustable along the running rail 2, and a pivot point 49 distanced from the pivot point 48 is guided by a steering lever 50 on a circular path around one Fixed point 51 is guided on the outer construction. This guide of the facade element 44 is preferably carried out both at its upper edge and its lower edge, but can also be done for example in the middle of the vertical extent.

The drive for the displacement of the carriage 1 along the running rail 2 can be done, for example, as in the anti-glare panels 32 of the previously described slatted curtain. Thus, the carriage 1 may be driven by means of a threaded spindle 39 approximately.

As Fig. 6 during the pivoting movement changes its position with respect to the carriage 1. While at about the running rail 2 approximately at right angles pivoted-facade element 44 its load, viewed in the direction of the running rail 2, approximately on Height of the carriage is and is very eccentric with respect to the track, is its weight load in the direction of the running rail 2 relative to the carriage 1 is offset with closed facade element 44 and this must absorb a load moment across the track 2, which by the arrangement of several, especially three one behind the other roller carriers 4 in a carriage 1 can be done well.

The materials used are selected according to the place of use, so for example when used outdoors for fastening facade parts a weight-saving design as well as a stainless surface is beneficial. The rails 2 can therefore be made of a light metal, in particular aluminum or an aluminum alloy in addition to a relatively inexpensive design in steel. The dimensioning of the cross sections is carried out according to the expected mechanical loads. Likewise, the roller carrier 4 may be made of a light metal. The rollers 5 can be made of stainless Stainless steel produced and stored with maintenance-free bearings on the roller carriers 4. In order to reduce the noise during the adjustment of the carriage 1 in the rails 2 while the running surface of the rollers made of a plastic such as PA, PE, PTFE, elastomer bebildet.
