Trim panel assembly, in particular for machines, with a sliding door and a roller assembly

The invention relates to a panel assembly, in particular a machine casing, with at least one sliding door and a roller guide assembly.

Sliding doors are typically at the top in a guide rail is mounted, and can in addition to the lower edge in a further rail out and / or be supported via rollers on the floor.

For machines with sliding panels is often the Panel to the working area of ​​a working table, said the workspace open upwards and therefore no Einhängemöglichkeit a sliding door the upper edge thereof is, and the sliding door not reaching to the ground and a support deleted by bottom rollers. In one developed by the applicant and z. B. in a leaflet "Bader Machine Covers" pictured in November 2003 machines with sliding doors is a roller guide assembly with a machine-side rail assembly and a door-side carriage assembly provided in which the Rail assembly has a low against the height of the sliding door height. The depth of the rail assembly is again much lower. The Carriage assembly on the side of the sliding door is in the lower range the lower edge of the sliding door arranged. In an upper portion of track assembly is a downwardly open guide rail and within the Rail arrangement deeper lying further to the side open guide rail attached to a common carrier rail. The guideways the guide rails have a convexly curved cross-section, in which Rollers are guided with correspondingly curved treads. The roller guide assembly takes advantageously very little space at the Machine in claim intercepts both the weight of the sliding door as well as the overturning moment from the direction of motion. About eccentrically adjustable Roles in the role groups can play at the guide or minimized even a slight bias of the role group in the guide rails be adjusted. With overlapping relatively sliding double doors can the further spaced apart from the rail assembly door means under the other door thoroughgoing brackets into the rail assembly be hooked. The carriage assemblies are then divided into two cars.

The present invention is based on the object, a further improved Such trim assembly with a sliding door and a particular this indicate suitable roller guide assembly.

Solutions according to the invention are described in the independent claims. The dependent claims contain advantageous embodiments and Developments of the invention.

The equipment of the role group with vertical axes, hereinafter also second roll group or second group named roles, with two subgroups Although each having a plurality of rollers increases the number of total inserted rollers and requires another track in the rail assembly and thus appears at first sight complicated, but brings Surprisingly, a number of significant advantages over the known Arrangement.

By only radial support of the roles of the two sub-groups in the upper or lower guide track, both the rollers and the guideways be carried out much easier and cheaper. The Roles can be used as cost-effective, stable and easy-running support rollers with only radial load on the roller bearing and with preferably circular cylindrical Roller rolling surface are executed, whereas in the known arrangement radially and axially loaded guide rollers with specially on the guide rails coordinated multi-faceted or used in cross-section convex treads are. The upper and lower guide track can advantageously each other and the roller axes of the subgroups parallel planar surfaces as have careers and can easily and inexpensively by forming a sheet can be produced. According to a particularly advantageous embodiment are upper and lower guide rail integrally in a profile rail, especially one from a flat sheet by bending, especially Folding, plate rail produced formed. The profile rail may, in particular the shape of a to the sliding door or attached to this have carriage assembly opened C.

By only radial support of the roles of the two sub-groups in the Raceways take these roles only horizontal forces. The vertical Forces, in particular the weight of the sliding door, are other trap elements of the roller guide, which preferably by the role group with horizontal roller axles, also referred to as first roller group or first set of rollers called, takes place. Conveniently, can these roles the first role group only radially on an associated be supported career as horizontal forces a pitching moment about an Traverse or longitudinal direction of the rail assembly by the vertically apart subgroups of the second roller group intercepted reliably will. The first role group can therefore also advantageously support rollers with only the radial bearing load and preferably circular cylindrical roller tread be included and associated with a flat surface as a career.

According to a preferred embodiment, the rollers are then in the first roller group for receiving the vertical and in the subgroups of the second roller group for receiving horizontal force components in only the radial run support on the associated raceways and used and Raceways in each case as to the roller axes parallel surfaces run. The Roller guide assembly may also total by an inclination angle is advantageously less than 30 ° preferably less than 15 °, mounted inclined be. However, typical and subsequently adopted as a standard case, the Mounting alignment with vertically aligned roller axes of the second roller group.

The track with the horizontal raceway for the first roller group carried out in an advantageous embodiment as a separate rail and one for the upper and lower guide path of the two sub-groups the second roller group common guide rail mounted. The guideway for the first roller group can advantageously be used as the sliding door be carried out channel section. The raceway for the first roller group may also be slightly inclined downward slipping possibly on the favoring career falling chips or other particles. The roller axes the first rollers are then advantageously likewise inclined and parallel to the runway. given the angle of inclination of such may Inclination of the raceway for the first roller group is advantageously less than 30 °, in particular smaller than 15 °.

The advantageously by only radial support of the rollers in the guide tracks level of the raceways tolerated conveniently a variable limited positioning of the rollers in the guide tracks in the direction of the roller axes. This is advantageous for example as regards the composition of the rail assembly of several separate Guideways for the different role groups, especially a common guide rail with upper and lower guide track for the Subgroups of the second roller group and an additional, common at the Guide rail mounted first guide rail with a running track for the first roller group. Minor variations in the relative positions affect of common guide rail and the first guide rail the function is not the arrangement. The same applies for tolerance deviations the relative positioning of the various role groups in the carriage assembly to each other and / or to the rail assembly. The position tolerant position of the roles of the various role groups in the associated guide webs is also advantageous with regard to any given differential thermal expansion of individual components of the roller guide assembly. A relative shift of the role groups in the guideways due to thermal expansion affects the function, particularly the ease and precision of the roller guide assembly not.

Advantageously, the second roller group at least three in the travel staggered rolls, of which at least one roller transversely to the direction of travel and transversely to the roller axis to a limited extent adjustable is. This may. As an eccentric exported to the roller axis be realized portion of a bearing pin which is connected to the eccentric Portion is fitted into a bore of the carriage assembly. Such adjustable Roles are available at low cost. In allocating the carriage assembly into two cars, which are spaced apart in the travel direction, are advantageously at each part Cart subgroups of the first roller group and the upper and lower part of the second group role group yet. Each the two sub-groups of sub-groups of the second roller group, that the Role group with the vertical roller axes, contains advantageously at least two single rolls, of which preferably in each case at least a roller transversely to the roller axis and is adjustable.

apart The breakdown of the carriage assembly in two in the travel Part Cart is per se from the machine covers the aforementioned known the applicant and in particular allows the overlapping Verfahrung two sliding doors in the same rail system. The part of the car Carriage assembly are advantageously at least 50%, especially at least spaced 75% of the width of the sliding door from the direction of travel in and preferably arranged on opposite edges of the sliding door. Preferably, the outermost in traversing roles of each Role groups, subgroups or subgroups close to the direction of travel in spaced side edges of the sliding door arranged.

The first role group can in a first advantageous embodiment of only two spaced in traversing rollers, but which then preferably wide apart, particularly in terms of door width of Sliding disposed marginal. The first track of the rail assembly for the first roller group can easily design only as a single track below the rollers of the first roller group be supported and the first roller group vertically running. preferably Embodiment, the first guide track two vertically spaced Guideways, between which the first roller group is guided so that a lifting of the first roller assembly upward through the first is limited or prevented guideway. The first role group can then contain at least three rollers, of which preferably at least one is adjustable transversely to the direction and transverse to the roll axis. at Distribution of the carriage assembly in two spaced part car can in a first simple embodiment, each depending on a portion Cart assigned subgroup the first role group only a role, in a preferred embodiment each at least, in particular precisely two rollers, one of which in each case an adjustable is included. Instead of the guideway with two first roller group therebetween enclosing raceways of the first guideway may also be provided a guide path in which a web strip away from one another on an upper surface an upper and on its lower side having a lower track and the first roller group with vertical Offset rollers above and below contains the web strip.

In another advantageous embodiment, a raceway for the rollers first group to which this rolling the weight of the door assembly is vertically supported, in one piece with at least one, preferably two Guideways be designed for the rollers of the second group. Especially can a raceway for rollers of the first group two raceways for Roles of a subset of the second group to connect. In a preferred embodiment , the rail arrangement of a one-piece profile rail consist of C-shaped cross-section.

The first rail S1 and the second rail S2 are connected in a defined relative position, preferably welded together.

In Fig. 2 is a situation with inserted into the rail assembly carriage assembly and by rail assembly and carriage assembly formed roller guide longitudinally movable sliding x ST sketched. In Fig. 2 outlines are in addition a machine cover with cover portions MV1, MV2 outlined, between which a door opening VO free is. The sliding door ST can along the rail assembly in the x direction between a closed position in which it covers the door opening VO, and an open position in which it substantially completely before the fairing section MV1 on which the user facing side is, be moved. The sliding door in FIG. 2 in an intermediate position sketched. Weight forces the door and tilting moments of the door of their weight will or other stresses during operation to all coordinate axes exclusively by the roller guide with the run in the rail assembly Carriage assembly collected.

In Fig. 3 in various views ((A) oblique view, (B), (C), (D) with Viewing direction in the x or y or z direction), a preferred embodiment of a Carriage assembly WA sketched for a fairing arrangement according to FIG. 1, FIG. 2. The carriage assembly includes a longitudinally x integrally continuous Carrier body TK of in the form of a rail and a plurality Supporting roles. The supporting roles are subsequently divided to distinguish in a first roll group R1 and a second roller group R2, which in turn is divided into an upper part group RU 2 and a lower part of group RU2. The rollers R11, R12 and R13 of the first roll R1 group are horizontal, ie pointing in the y-direction roller axes on a vertical surface F1 of the support body TK attached. At least one of the rolls, the roll axis eccentrically against the roller position-determining hole in the face F1 and the position of the roller axis is adjustable in such a Role in the z-direction, ie x transversely to the roll axis and transversely to the adjustable to a limited extent. The roller shaft of the middle roller R12 is compared to the roller axes of the rollers R11 and R13 low by an amount AV1 in the z direction is displaced upward. The outer rollers R11, R13 of the first Role group are positioned far apart in the x direction and preferably close to the opposite edges of the supporting body TK mounted thereon. The role R12 is advantageously approximately in the middle the carrier body is arranged in the x direction. The rollers R021, R022, R023 and R024 the top group R02 of the second roller group at a horizontal top surface F02 of the carrier body with substantially vertically aligned roller axes fixed. Preferably again, the x-direction outer rollers R021 and R024 far apart and particular close to the opposite edges of the carrier body or its surface F02 attached. Notwithstanding the allocation of the first Role group in the example shown the upper part of the group R02 second roll group between the outer rollers R021 and R024 two more rollers R022 and R023 are provided which close to the outer Rollers are arranged and against these turn a slight horizontal Axial offset AV2 show in the y direction. The pairs spaced Roles can, in anticipation of a later to be described in more detail Example as subgroups are considered within the subgroup R02. Advantageously, in turn, be provided that in each subgroup at least one of the rollers transversely to the direction of travel and transverse to the roller axis, that is, in this case, in the y direction, by a small amount is adjustable. A lower part group RU2 the second roller group is analogous to the top group R02, so that the made to the sub-group R02 Explanatory comments. While the roles of the top group of the mounting surface F02 have upwardly, the rollers RU21, RU22, RU23 and RU24 of a horizontal bottom mounting surface FU2 the carrier body TK down. It is also more subgroups as outlines and / or be provided each subgroup more single roles. The sketched Distribution, however, is particularly advantageous.

The carrier body TK still further comprises an upper vertical support surface FBO and a lower vertical support surface FBU, via which the support body directly or via intermediate elements on the user side remote the sliding door may be fastened. The vertical spacing of the two holding surfaces results in a stable connection between the carrier body and sliding, which in particular for collecting tilting moments is about the x-axis advantageously suitable. The mounting surface for the rollers F1 the first roller group is against the holding surfaces FBO, FBU in x-direction offset towards away from the user and to the rail assembly SA, which on the one hand on the sliding door side facing the mounting surface F1 course is for the mounting screws onto the threaded bolt of the support rollers and the other of the rollers themselves closer to the vertical rear wall Rail assembly back what for supporting the weight of the door in a guide track for the first roller group R1 is advantageous.

If no relevant tilting moments, the sliding door about an y-direction axis parallel are to be expected, the central roller of the first roller group R12 also be omitted or replaced by a simple stop element be. In still other embodiments may also be in the first roller group x-spaced sub-groups, each with at least two rollers provided analogous to the described structure the upper and lower part group be. The sub-groups may be more than two, in particular three have individual roles.

In FIG. 4 is a preferred embodiment of a rail arrangement with a used car arrangement sketched in Fig. 3 Art and looking in x-direction shown. The track assembly includes a first guide track for the rollers of the first roller group R1, an upper second guideway for the roles of the top group R02 and a lower second guide track for the roles of the lower part group RU2. The upper second guideway is formed by a U-shaped, downwardly open profile section, whose vertical profile leg connected via an upper center portion OF at the mutually facing inner surfaces of a front profile Career L02V and a rear track form, which by the axial offset AV2 of longitudinally spaced individual rollers of the top group some roles such. as R021 and R024, at the front and career L02V other rolls in the y-direction offset roller axles on the rear track L02H are supported. Between the axle of the rollers and the upper connecting central portion OF is a slight distance, which to a manufacturing tolerances and other small vertical displacements between the sub-group R02 and the upper second guide track, z. B. by different thermal expansion of rail assembly and Carriage assembly permits.

Correspondingly, for the roles of the lower part group RU2 a lower second guide track in the form of an upwardly open U-shaped profile section be provided connected at its central portion via a UF vertical profile limbs a front and a rear career LU2V Career LU2H formed. The clearance between the axle of Roles of the subgroup RU2 and the central portion of UF has still the special Effect that the lower profile portion incident smaller particles, in particular chips, a material processing operation, the Verfahrung not affect the carriage assembly. The central portion may UF for this effect also be set lower than in the drawing and / or breakthroughs exhibit by which such particles turn back down can.

The lower and / or the upper profile section can in a preferred embodiment, by forming, in particular rollers or folding a be formed sheet section. The upper and the lower profile section are advantageously connected to each other via a vertical rear face RF and preferably open with this as one piece to the carriage assembly toward C-track running. The back surface can, in particular in the form of openings for the passage of fixing elements, such. as screws to Fixing the rail S2 to be prepared on a machine frame. The Rear face RF is made plane in outlined preferred example.

A first guide track for the rollers of the first roller group R1 is in the example Rail arrangement according to the FIG. 4 by a first rail S1 in the form of one formed the carriage assembly toward the open U-section, the inner profile surfaces a lower track and an upper track L1U L10 on the horizontal form profile arms. The connecting the two profile limbs Central portion is advantageously used for fixing, preferably welding facing the first rail on the carriage assembly Side of the rear face RF of the second rail S2.

The rollers of the first roller group based substantially the weight of the Sliding off at the lower raceway L1 U. With more than two roles in the first role group, as in the example of FIG. 3 roll advantageously at least two rollers on the lower raceway L1 U from, these rollers advantageously are x widely spaced longitudinally such. as the rollers R11 and R13 of Fig. 3. The vertical play these two roles within the first guide path may in unfavorable situations in a slight, by conditioning one of the two rollers on the upper track L10 and / or by investing bearing pin by rolling the top group the central portion OF limited tilting movement of the sliding door about an y-axis parallel tilt axis lead. Such tilting can from the front are in inhibited by at least one more role, such. as the R12 role in the example of FIG. 3 which is a vertical axis offset AV1 having against rolling on the lower raceway L1 U rollers and optionally with slight pretension constantly on the upper track can rest and roll L10. If such a tilting movement about an not expected y-axis parallel tilting or because of the low Kippspielraums is not considered serious, may in the first guideway also only a lower raceway L1 U be provided. The rollers of the first Role group are parallel to its inside the first guideway Roll axis to a small degree variably positionable, which advantageously again Positional tolerances between the positions of the first rail S1 on the rail assembly and the first role group on the carriage assembly and / or changes in position by thermal expansion permits. The lower Career L1 U can in others, not sketched design also easy to extend carriage assembly toward inclined downwards to the depositing Particles to act on this track meet. Advantageously, then the roller axes by the same angle, which is preferably against the Horizontal (y-direction) is less than 30 °, in particular less than 15 °, inclined and extend again parallel to the lower track. The upper run L10 is then also inclined and parallel to the lower track.

The first track is advantageously vertically between the top and the lower guide track and preferably in the y direction between the front and rear tracks of the upper and lower guide rail. The Rollers of the upper and lower sub-groups of the second roller arrangement have advantageously a small diameter, the depth of the rail assembly to keep low. The rollers of the first roller group can having a diameter greater contrast.

For the formation of the tracks and corresponding arrangement the roles of the various role groups, especially the first roller group are deviating different from the embodiment described above Variants are conceivable, which has the advantage of only radial load the rollers in the guide tracks and thus the choice of long-lived, low rolling resistance and cost-effective support rollers retained.

In Fig. 5 (A) is an example of one flat sheet, z. B. by Roles and / or folding manufactured rail arrangement shown in which the upper and lower guide tracks for the rollers of the upper and lower subgroup, as shown in Fig. 4 as a downward or upward open U-shaped Profile sections are executed. The back surface RFS forms in shape an upper loop OS and a lower loop US two projections in Direction of the carriage assembly and the sliding door. The two projections form facing with each other, vertically spaced raceways and L10 L1 U a guide track for the first role group with the function of the first Rail S1 of FIG. 4. It is here advantageously only a small transform sheet metal part.

In FIG. 5 (B) is a modified form of FIG. 5 (A) outlines in which only forming a lower protrusion US from the rear surface to the sliding door towards is that with its overhead portion, a lower raceway L1 U for the first roller group corresponding further career needed or desired is to even small tilting motions about an axis parallel to the y-axis prevent tilting axis, such a future career z. B. <ul><li>by the downward surface of the upper central portion OFL OF can be formed, for which at least one roller of the first roller group vertically upwards and in the x direction against the rolling of the top group R02 is staggered.,</li><li>by the downward surface of the lower portion USL US be formed, for which at least one roller of the first roller group vertically offset downwards below the projection US disposed,</li><li>by the downward surface of the lower central portion UFL be formed UF what at least one roller of the first roller group is disposed below the lower edge of the first rail.</li></ul>

Even for the weight of the sliding door on a track of the first Guideway supporting, at least two rollers R11, R13 of the first Role group may be arranged differently and z. B. to the upwardly facing surface of the upper central portion OFO OF or at the Top support-facing surface of the lower central portion OFO UF so that u. U. to a separate structure as the projections OS, US or the first Rail S1 can be omitted for the first track.

In Fig. 6, a carriage assembly at the bottom of a sliding door is sketched, wherein two in the displacement x apart, in particular at most spaced part cart TW1, TW2 are provided, each Subgroups of the first roller group and the subgroups of the second Role group. Each subgroup UGOR, UGOL, UGUR, UGUL the Subgroups of the second roller group advantageously contains at least two, preferably exactly two single rolls, of which advantageously in each case at least one single roller in the y-direction is adjustable. The distribution the rollers of the second roller groups is in the carriage assembly of FIG. 6 substantially the same as in the carriage assembly of FIG. 3, but not continuous in the travel profile is provided as a support body, but two spaced part Cart TW1, TW2. The separation of the carriage assembly into two sub-carriage is particularly advantageous for the in x-direction overlapping Verfahrung two staggered in the y direction to today Sliding doors with in traversing offset and cross each other Carriage assemblies each with two separate part in the same car Rail arrangement. For the user-facing sliding door are part Cart in particular formed with a bottom edge of the user facing away sliding under cross beams. The division of Carriage assembly into two cars is per se from the aforementioned Prior known art.

The subgroups UG 1 R, L UG 1 of the first roller group with substantially horizontal roller axles each containing at least one roller. A second role in each of these subgroups can with axial offset AV1 in the z direction be provided to a tilting movement in the manner described the door to prevent.

In Fig. 7 is an oblique view of a preferred embodiment of a part of the carriage outlines, in which a support body TT, which is advantageously in one piece consists of an angled sheet that the carrier body TK of FIG. 3 corresponding surface portions for fixing rollers and fixing comprises the part of the carriage on the sliding door. In addition to the particularly 3 described advantageous multiple folded profile shape as to Fig. In detail can advantageously in the angles between upper and lower Mounting surfaces for the rollers and the vertical support surfaces for attachment provided the part carriage at the door still bent tabs BL be, which, for. example, to reinforce the profile and / or for the attachment of can serve bump stops AP. Fig. 8 shows a sectional view through a roller guide Cart with a part of FIG. 7 in a rail arrangement as in Fig. 4. The depicted in Fig. 7 and Fig. 8 is part car by easily produced and compact design is particularly advantageous.

Fig. 9 shows a carrier body for rolling a part carriage according to FIG. 7 in other embodiments. The main difference compared to the embodiment is shown in FIG. 7 that the raceways for the rollers of the first group not in a vertical portion between the raceways of the spaced vertical Subgroups of the second group of rollers are, but with this on nearly the same amount.

The carrier body according to FIG. 9 in the oblique view of the clarity half drawn without the rollers. The roles and their alignment result themselves. from the marked bearing bores L10, L1 U, L20 and L2U Of the Support body is advantageously carried from a flat sheet metal blank Multiple folding manufacture. In particular, the individual surface sections with the bearing bores for receiving the roller axes in projection surfaces a wall plate VW formed. The wall plate VW has built in State of the sliding door to and is advantageously on a vertical Panel of the sliding door secured. In side surfaces parallel to the x-direction lying surface normal turn are openings for attaching LP provided by Buffer elements.

In Fig. 10 is a partial carriage with a carrier according to Fig. 9 including it, rollers mounted in a state inserted in a rail arrangement in a viewing direction y on the wall surface VW (View A) and in two Views in the x direction as a stepped partial sections on the amount of roles RHO, RHU with vertical roll axis (Fig. 10 (B)) or roles RVO, RVU with horizontal Roller axis (Fig. 10 (C)) are shown.

The rail assembly is in this preferred embodiment only from a one-piece profile rail with, in cross section according to Fig. 10 (B) or Fig. 10 (C) C-shaped profile. The rail SC corresponds to substantially the rail S2 of FIG. 4, in which and in the embodiment of FIG. 9 Fig. 10 No additional rail as a guideway for vertically supported Rolls the first roll group is provided.

The roles RHO, RHU the second roller group with vertical roller axes With respect to function and in a vertical arrangement largely the rollers R02 and RU2 the second roller assembly of FIG. 4. In the example shown, includes the second roller group with the vertical roller axes in a lower only role group a role RHU and in an upper roller group two roles RHO. The guidance of the rollers of the subgroups of the second roller group the vertical roller axles can substantially again as in the embodiments already described occur. In particular form one hand faces the rear wall of the profile rail CR SC an upper rear Career COR and a lower rear career CUR and those in the y direction horizontally spaced opposing inner surfaces of vertical angled legs of the C-profile form a front upper run COF or a front lower career CUF.

In the top group with rolls RHO can be provided again that one of the rollers is adjustable in the y-direction to one of the rollers at the RHO COR rear career and another of the rollers to the front RHO Career COF rest let. However, the two rollers can also RHO with aligned in the x-direction or in the y direction to the same extent on the arranged panel VW spaced positions their roller axes be. A small play of roles between the opposing raceways in the order of fractions of a millimeter can consciously be accepted. Also for the lower roller of the lower RHU Subgroup of the second roller group results if not more special Measures are provided, such a small amount of play of fractions of a millimeter in the y direction.

The front and rear tracks COR, CUR or COF or CUF for upper and lower rollers of the second roller group by horizontal Profile leg OF or UF connected to the rear wall of the profile rail CR SC. This vertical profile limbs serve in the embodiment of FIG. 9 and Fig. 10 advantageously together with their inner surfaces as a lower roller track CU for the lower rollers RVU the first role group or as an upper Career CO for the upper rollers of the first roller RVO group. The weight associated with at least two partial car door is exclusively by the lower rollers RVU the first roll on the CU career of lower profile arm UF supported. The upper rollers RVO the first roll serve primarily to a tilting of the Door in order to prevent a parallel to the y-axis. The upper rollers RVO are therefore typically only exceptionally in shifting the Sliding on the upper tread CO on. The upper rollers can RVO hence by a simpler Kippbegrenzung, for example, one of the VW wall surface continuing tab may be replaced or when no tilting moment is expected to parallel to the y-direction tilt axis, even be completely eliminated. In other embodiments, the vertically spaced rollers RVU, slightly biased RVO the first roller group also for vertical play-free guidance be conducted in the rail SC, in particular the one upper roller RVO this role group supporting lug resiliently can be carried out. can also in the rollers of the second roller group individual roles limited his spring-mounted resiliently and with elastic applied bias to the treads.

The given to the above embodiments, annotations are modifications of the specific examples outlined, in particular as regards the rollers of the first group and the continuous or in two sub-carriage divided carriage assembly also to the example of FIGS. 9 and 10 transferable. Rollers of the first group can also click on the outer top running surface of the upper horizontal profile leg OF and vertically supported be.

In Fig. 11 a roller guide assembly with particularly low installation depth is y-direction in two versions (A) and (B) outlines. Typical of these roller guides is that the rollers used in the roller bearings both radially and axially and in guide tracks also radially and axially are performed with respect to the roller axes. Example of FIG. 11 (A) are rollers used RV, whose uneven roller treads ago by the axial edges in cross-section towards the center of the roller rolling surfaces conically toward each other running, own against the roller axis obliquely inclined roller treads. The roller guides in a profile rail SV which advantageously as Rail by folding or rolling or other Transform a flat Sheet is prepared, are the roller rolling surfaces adapted raceways in provided against y- and z-direction inclined orientation. The roles RX, whose roller axes are fastened on a carrier plate VT, with their FV roller rolling surfaces both radially and axially in a defined position in the Rail SV performed. Again, there are upper and lower sub-groups of Rollers provided which in accordance with vertically spaced own Guideways the rail SV are performed.

In Fig. 11 (B) is a design sketched, where an upper rollers Subgroup to another, non-cylindrical shape of the roller rolling surface with FK having a recess the roller rolling surface to the axial center of the roll out. In this deepening Rollenlauftlächen FK roles RK the top group engages an angled downward extension of the rail as SK Guideway LK one. The roles of the RK top group are substantially axially loaded relative to their roller axes to tilting a Sliding door assembly about an axis parallel to the direction of the tilt axis to prevent. A radial load of these rollers occurs when they are not with elastic applied bias to the upper guide rail, only in exceptional cases at a tipping load of the sliding door assembly in the process in the x direction on.

Fig. 12 shows a further advantageous form of a roller guide assembly with a guide rail which on both sides to the vertical inclined Raceways FGO. FZO in an upper guide region (Fig. 12a) and having FGU, FZU in a lower guide region (Fig. 12b). The roller axes first and second rollers in upper or lower guide region are also inclined to the vertical and substantially parallel to the Raceways, so that the rollers are in turn only radially loaded. The angle of inclination the raceways and roller axis to the vertical or generally is located against the rear surface RS of the C-shaped guide rail SCK advantageously between 30 ° and 60 °, preferably ± 45 °. The angle of inclination different races can deviate from the sketch 12 can be different according to FIG..

In FIG. 12 is a top career-guide portion of the guide rail SCK with a front sloping track FGO for a first upper roller with RZO to FGO parallel roller axis and having a career FZO for a non-illustrated second upper roller shown with parallel to FZO roller axis.

In a corresponding manner, the guide rail in a lower SCK Guide portion of Fig. 12b is a front sloping track FGU for not drawn first lower roller and a raceway FZU for a second lower roller RGU.

The angle WO up or down between the differently inclined WU Raceways not serve as running surfaces and therefore additional structures have or be used for attaching other components. For example AUL can provided in the lower angular recesses be, through which the guide rail incident chips or other particles can be ejected, z. B. by the roller assembly comoving brush assembly, sweeping lip or the like. Appropriate Outgoing ports can also in arrangements with vertical and horizontal Support surfaces and treads in the lower guide portion in the rear and / or the front corner of the U-shape of the guide rail can be provided.

The characteristics indicated above and in the claims and Figures removable features are both individually and in various Combination advantageously realized. The invention is not limited to the Embodiments limited but expert under modifiable skills in many ways. The roller guide is not only in the application for the sliding door of a machine casing, but also otherwise used advantageously.
