Description

The invention relates to an underfloor pull-out guide in one Cabinet body with pull-out drawers and the like With one attachable to the body wall, as a profile rail trained guide rail and one on the drawer in the area of the drawer bottom or the underside of the drawer side wall attachable, designed as a profile rail, which by provided on the two rails Rolling bearing elements rolling a longitudinal displacement enable the running rail relative to the guide rail, with a profile section at the inside end of the running rail from a lengthways to the top track aligned first position in a contrast essentially parallel to the drawer rear wall second position is pivoted, and in the inside of the body of the guide rail and on the track section articulated interacting Guide means are provided which cover the profile section during the movement of the track on the Guide rail from the fully extended position of the End position assigned to the drawer in the drawer insertion direction when its inner end approaches the Corpus rear wall increasingly in the drawer rear wall parallel swivel the second position.

With pull-out guides, where only one on the cabinet body Guide rail to be fastened with a to the Drawer to cooperate with the rail to be provided is the Stroke - regardless of the special design of the pull-out guide - limited to a path that is shorter than the drawer depth of the associated drawer is such that the rear wall of the fully extended drawer is still around a specified dimension within the associated cabinet body stands. Such pull-out guides are therefore also called "Partial extracts" or "single extracts". In particular with low drawers of very great depth it is in extended condition still inside the cabinet body rear drawer area then difficult to see and accessible. It would therefore be desirable to have the pull-out guides can also be produced as so-called "full extracts" in which the associated drawer as far out of the cabinet body can be pulled out that their rear wall is approximately flush with the front surface of the cabinet body. As far as such So far "full pull-outs" are offered, they become practical as a combination of two partial or single pull-outs so-called "double statements" received. With roller pull-out guides, where both the guide rail and the Track in a space between the inner surface the body side wall and the outward-facing side surface the associated drawer, i.e. the Height has little importance because of the total height the side wall of the drawer is available such "double extracts" used on a large scale. On the other hand are "double pull-outs" in which the arrangement is under the floor Underfloor pull-out guides to be used, in which the Running track in an elongated cage Held rolling elements on roller tracks of the guide rail is stored, can only be used in special cases because the vertical Overall height increased significantly with these pull-outs will, thereby increasing the protrusion of the side walls the drawer or raising the drawer bottom in with respect to their height arrangement in the side wall must, if the track assembly is not undesirable should be visible on the underside of the drawer. But this also increases the drawer's capacity decreased. On the other hand, such roller bearing Pull-out guides due to the variety of not only in Extending direction, but also at right angles to it spatially offset rolling elements in the form of balls and / or rollers in addition to their smooth running and high resilience additional advantage that they - even in the fully extended Condition - have a high degree of lateral stability, so that a drawer stored with them in a cabinet body even when fully extended in a horizontal position Transverse direction has no noticeable play. For storage of drawers in high quality furniture Increasingly, such pull-out guides are used. Another advantage is the possibility for the Running track used hollow profile with a low overall height produce, so that the track - in the so-called. "Underfloor arrangement" - at the bottom of the floor one Drawer immediately next to the something above the floor side wall protruding below - or - if the side walls the drawer of hollow profiles open at the bottom be made of metal or plastic - within the Sidewall can be arranged. This makes it possible the width of the drawer compared to roller pull-out guides, the one space between the outside the side wall of the drawer and the facing inside the body bulkhead require to enlarge.

In cases where the capacity of the Drawer is less critical, was also tried with Simple extracts to give the appearance of a full extract, by pulling the drawer in the drawer pulling direction about the size of the cage of the pull-out guide shorter was while the running track with the greatest possible Length was used. Those facing the back of the body End areas of the slide rails supporting a drawer so you still step into the back of the drawer Interior of the body. Because the protruding areas of the track are covered by the back of the drawer this is not the case with drawers installed in the cabinet body, however of course the drawers have a corresponding one their lower depth, reduced capacity.

In the case of pull-out guides designed as roller pull-out guides (DE-A-29 46 113) has also already been proposed to involve a full statement in that instead of Insertion of another intermediate rail on the rear End of the running rail on a vertical or horizontal Additional tiltable track part attached to the axis is when the drawer is pushed in when approaching to the completely closed position by a positive control so up about the horizontal axis. the vertical axis inwards in front of the rear wall of the drawer is pivoted that the drawer can be inserted further is. When pulling out, it then puts back with the actual one On the other hand, the running rail part is in alignment an additional suit route is available that is a full pull-out the drawer allows. Have in practice such full extracts were not introduced.

The closest prior art document DE-A-3 702 238 discloses an underfloor pull-out guide for drawers and the like which can be pulled out in a cabinet body, with a guide rail which can be fastened to the body wall and is designed as a profile rail and one on the drawer in the area of the cabinet The bottom of the drawer or the underside of the drawer side wall can be fastened, designed as a profile rail, which enables a longitudinal displacement of the running rail relative to the guide rail by bearing elements rolling on the rolling tracks provided on the two profile rails.

wherein the guide rail is profiled in a channel-like manner and has an elongated flat profile leg that can be fastened to the inside of the body side wall, an elongated profile leg that is bent away from it and runs essentially horizontally, and an edge that faces away from the body wall into an essentially parallel to the profile leg that can be fastened to the body wall Layer has edged profile legs, on the free upper edge of which the rolling tracks are formed for roller bodies held in an elongated cage, in the drawer pulling direction and at right angles to the drawer pulling direction, offset from each other,

and wherein the running rail is designed as an open through-slot on its underside for the profile leg of the guide rail which carries the rolling tracks, and in the interior of which the rolling tracks for the rolling elements held in the cage are formed.

The invention is based on the object that advantageous rolling element bearings to be used in the underfloor arrangement To improve pull-out guides so that the with single pull-outs otherwise loss of pull-out is inevitable disappears without an enlarged vertical Height of the pull-out guide results.

This object is achieved by the features of Claim 1.

Surprisingly, it turned out that the pivotable articulation of the hollow profile section on rear end of a cross-sectionally similar hollow profile formed track with sufficient accuracy can be carried out so that even when the Rolling element cage or the rolling elements held in it via the interface between the hollow profile section and there are no stalls or inhibitions on the running track. On the other hand, it actually becomes an additional one Extension path in the length of the hollow profile section Provided that makes it possible, even comparatively deeper drawers, the back wall of which is fully inserted Position brought up close to the back wall of the body are to be pulled out so far that the loss of extension due to the Wälzköprer cage is balanced. Correspond in height the pull-out guides, on the other hand, are single or partial pull-outs of the same genus.

The swivel axis of the hollow profile rail on the running rail can either be horizontal or vertical at right angles to the direction of displacement of the track on the Guide rail extend, the hollow section in the the former case preferably from the to the track aligned position in a swung up against it Position is pivoted while in the second Case a pivoting from the adjacent cabinet side wall away from the back wall of an associated drawer.

To control the swiveling process of the hollow section is in a preferred development of the invention on End of the back wall of the body forming the guide rail Profile rail one of its longitudinal extent in the pivoting direction of the hollow section pointing control section attached, the guide means then on Provided hollow profile section when approaching the Drawer closing action engages with the control section have coming control element.

The configuration can advantageously be made such that the control section on a provided on the guide rail, longitudinal guide engaged with the control member connects.

When the hollow profile section is pivotable about a horizontal axis hinged to the inside of the running rail is, the longitudinal guide is appropriate from one of one Profile legs that can be attached to the body wall including the profile rail forming the guide rail of the control section essentially at right angles Material strips protruding inside the body and the control element from one of the hollow profile section towards Guide rail protruding and at least on one side of the strip of material held in contact projection.

If, on the other hand, the hollow profile section is vertical The pivot is articulated axis, is the design expediently taken so that the longitudinal guidance of one strip-shaped material area of at least one of the in the intended mounting position parallel to the assigned Body wall extending profile leg of the Guide rail forming profile rail is formed, which or which in their end area inside the body in the Reduced height and from its body-parallel course is reshaped in the direction of the course of the control section or are, and that the control member of at least one of Hollow profile section protruding and at least on one side of the strip-shaped material area or the material areas held in plant Projection is or will be formed.

The control element can also be from two to opposite Projections adjacent to the material strip are formed, which then a positive control of the Swiveling operation of the hollow profile section is given.

In any case, it is recommended to have the lead or the Projections at least in the area of his or her plant on Strips of material with a friction-reducing surface, for example to provide a suitable plastic pad, the drawer is stiff when it is pulled out to avoid or insert.

For this purpose, the configuration can also be made in this way be that the projection or the projections of each one rotatably mounted on the hollow profile section, with her Roll peripheral surface on one side of the material strip Tax role is or will be formed.

Especially when the control element from only one one side of the strip of material held in contact is formed, it is recommended to use the hollow section resilient in the direction of pivoting from the first to bias into the second position. This bias not only causes the control element to rest on the material strip, but leads - if the dimensions are sufficient Preload of the spring used - at the same time that the drawer when inserted through the opposite of the Running track pivoting hollow profile section when approaching resilient to the closed position in the fully closed position Position is drawn. I.e. without additional constructive Effort is the function of an automacic Drawers can be pulled in.

Due to the fact that the pull-out guides according to the invention drawer stored in a cabinet body is extendable from the cabinet body than usual with a normal extension, the bending stress also increases the rails of the pull-out guides in all extended State in which the rail cover of the Running and guiding rail essentially only the Corresponds to the length of the rolling element cage. It is advisable therefore, at least at the outer end of the guide rail one the running rail in the fully extended position to provide the projection supporting the drawer, thus in the fully extended position of the drawer in addition to the end of the cage facing away from the rear wall provided rolling elements the loads of transfers the running rail to the guide rail. Also here it can be useful again if the lead or the projections at least in which the running rail supportive area with a friction-reducing Surface is or are, the projection also from one rotatable to one inside the running track Profile leg of the guide rail mounted on the inside of the web section of the rail forming the Hollow profile rolling role can be formed.

To prevent the drawer together with the running rail be pulled out of the body by the intended dimension it is advisable to use the back of the cabinet One end of the material strip forming the longitudinal guide To provide a stop for the control member on which the Control member starts in the intended extended position.

If the control element is formed by a control role, can then stop from a radius of the control roller according to an arcuate end section of the Material strip be formed.

On the the hollow section section resiliently in the direction of a Swiveling spring in the second position can be dispensed with if this pivoting in the closed position by appropriate design of the Control section inevitably takes place. According to an advantageous Further development of the invention can achieve this be that between two to the hollow section occurring and the control member fitting between them and leading boundary walls a control curve is formed.

The control element is also useful in this case as Control roller mounted rotatably on the hollow profile section, whose diameter is essentially equal to the distance between the facing surfaces of the cam boundary walls is measured.

It is recommended that the height of the facing one another Areas of the cam boundary walls are equal to or slightly larger than the width of the peripheral area of the between the tax roles recorded between them, and from the edges facing the hollow section rail section the boundary walls each short, the control role something encompassing the hollow profile section on the circumferential area Letting strips of material come forward, creating an unwanted Steering roller exits the cam with Security is excluded.

In this case, the control section is expedient as on provided inside the body end of the guide rail, separately manufactured and fastened on the guide rail flat component made of plastic.

The control section is preferably made of a thermoplastic Made of plastic, from which to Attach the guide rail to the carcase bulkhead Guide rail profile leg facing side step forward short integrally attached fastening pins, which reach through holes in the profile leg and at their free ends by hot forming into rivet heads are reshaped.

1 to 3 in its entirety is 10 designated embodiment of one in the invention Underfloor pull-out guide in three different positions, namely the drawer closed position, a partially extended drawer and the position corresponding to the fully extended drawer the running rail shown on the guide rail, wherein in Figures 1 and 2, the outline of an associated Drawer are indicated by dashed lines.

The version 10 has a sheet metal to a channel-shaped Profile canceled guide rail 12, whose a vertical profile leg 14 on the - not shown - Inner surface of the side wall of a cabinet body - preferably by screws - can be attached. From the bottom Edge of the profile leg 14 is an elongated strip-shaped Web section 16 folded at approximately a right angle, from its edge facing away from the profile leg 14 another Profile leg 18 folded upwards at right angles is. The height of this profile leg measured in the vertical direction 18 is significantly less than the height of the profile leg 14. At the upper free edge of the profile leg 18 are formed from the material of the metal sheet Raceways for rolling elements, with a horizontal axis arranged rollers 20 and on opposite sides balls 20 which are displaced downward from the rollers 20 and which in a cage 24 at a predetermined distance and in the intended position rotatably supported relative to each other are. On the rolling elements is the hollow profile rail with an approximately reverse U-shaped cross section Track 26 mounted longitudinally displaceable, which in the present Case for mounting on the underside of the floor a drawer 28 immediately adjacent to the drawer bottom assigned drawer side wall protruding downwards is determined. Unless the side wall of the drawer from a hollow metal frame open on the lower face is formed, the track 26 can also in the open underside of this metal frame. in the the extent described so far agrees with the extension guide the known pull-out guides of the same type.

In a further development according to the invention is on the inside of the body End of the track a hollow section by a right angle to the drawer insertion direction and horizontal Swivel-mounted axis. This hollow section 28 has one with the one forming the running rail Hollow profile matching cross section. The linkage of the Hollow section 30 at the inside rail end of the body takes place so that this hollow profile section between the two end positions shown in Figure 4, namely one first, in alignment with the end of the running rail 26 (see also Fig. 2 and 3) and a second, in contrast End position pivoted upwards by about 90 ° (see also Fig. 1) is pivotable. Since the hollow profile section 30 on End of the entire length of the drawer Running rail 26 is attached, it is in the first End position still in full length from the rear wall of the Drawer 28 in front. The pivoting position of the hollow section 30 is controlled in the manner described below so that it covers most of the insertion or Moving out of an associated drawer in the first end position is held, in which the rolling elements 20, 22 holding cage 24 at least partially from the Track 28 in the hollow profile section 30 - and vice versa - can cross. Only when the Drawer on the rear wall of the associated - not shown Cabinet body to such an extent that the free end of the Hollow section 30 threatens to hit the rear wall, becomes the hollow section section 30 up into the second End position swiveled. The one holding the rolling elements 20, 22 Cage 24 is then completely in the running rail and does not hinder this pivoting process.

Near the free end of the hollow section section 30 is a control element in the form of a parallel to the Pivot axis of the hollow profile section 30 extending axis Control roller 32 rotatably mounted on the hollow profile section provided, the peripheral surface of one in the upper edge region the guide rail 12 provided longitudinal guide in Form of an integral on the leg 14 of the guide rail 12 cut and folded at right angles into the interior of the body Material strip 34 is pressed and unroll can At the rear wall end of the body of the guide rail 12 forming rail is one of them Longitudinal extension in the direction of pivoting of the hollow profile section sloping control section 36 integral scheduled. The material strip 34 sits in this oblique control section 36, being in the transition area between its horizontal course on Leg 14 and the oblique course on the control section 36 is rounded. In the area of the control section 36 Material strip 34 so wide that it is the peripheral surface of the Control roller 32 completely covered. At the free, i.e. the profile leg 14 facing edge of the material strip 34 then a narrow strip-shaped rectangular folded material section 35, which grips the control roller 32 laterally and thus ensures that the control roller is not on the side of the material strip can slide off and jam.

FIG. 4 shows that the hollow section section 30 one hand and the rear end of the track 26 in the vicinity of the pivot axis of the hollow profile section coil spring 38 under tension which the hollow profile section 30 normally in the second, i.e. pretensioned end position and thereby the control roller 32 against the underside of the strip of material 34 urges. In the fully retracted position the circumference of the control roller 32 is on the drawer outer upper end of the protruding from the control section 36 Strip of material 34. If the drawer is then pulled out, rolls the control roller 32 on the material strip and the hollow profile section 30 is increasingly in the direction of pivoted first end position, which is then reached if the control roller is on the horizontal section of the Material strip 34 passes. In the area where the Control roller 32 in the fully extended position of the drawer stands, the material strip 34 is at 34a with a approximately arc corresponding to the radius of the control roller 32 bent downwards, whereby this end portion 34a a Stop forms, beyond which the track 26 with the attached hollow profile section 30 is not pulled out unintentionally can be. The control roller supports in this end position 32 also the weight of the drawer and its contents over the material strip 34 on the guide rail 12 from. It may be advisable to use additional support between the track and the guide rail in their to cause the front end region in that an additional on the guide rail 12 provided projection the running rail supported from below in the fully extended position. The rolling elements 20, 22 are thereby in the whole extended position relieved.

The spring 38 described above not only the pivoting process of the hollow profile section 30 at the Controlled approach of the drawer 28 to the closed position, but it also causes the over the control roller 32 supported on the material strip 34 Spring force acting in the direction of retraction of the drawer Moment created, i.e. it is also the function of a automatic drawer retracted.

In Figure 3 it can be seen that in the fully extended end position the cages 24 holding the rolling elements 20, 22 from rear end of the rail 26 still in the hollow section 30 steps forward. Especially if the Weight of the drawer on the guide rail 26 on the guide rail 12 transmitting upper rolling elements in the described Formed as rollers 20, it is expedient when aligned with each other Track 26 and hollow profile section 30 between the adjacent rear end edges of the running rail and the front end edges of the hollow profile section Parting plane not at right angles to the direction in which the rails are pulled out run, but in the top view this slightly offset at an angle, so that in the cage 24 with rollers 20 guided at right angles to the direction of extraction Roll the parting line diagonally, resulting in a soft, brisk Passes the rollers 20 from the rail 26 in the Hollow profile section 30 - and vice versa - leads, which not in the form of stalls or chattering noises noticeable.

In Figures 6 to 8 is a second, in its entirety 110 designated embodiment of an inventive Extending guide illustrates that of the above largely corresponds to the pull-out guide 10 described, so that it suffices below Describe changes while matching for the Design features suffice for the previous one Reference to description, especially since functionally identical components both embodiments in the drawing figures are assigned the same reference numerals, which in the case of second embodiment just preceded by a "1" is.

The basic difference of the pull-out guide 110 for Pull-out guide 10 is that the hollow section 130 can be swiveled around a vertical axis on the inside of the body end of the track 126 is arranged. The Control roller 132, which the hollow profile section 130 aligning most of the extension or insertion path aligns with the actual running track 126, is on the rear side End of the hollow profile section rotated in this way stored that its circumference on the profile leg 114th of the guide rail 112 facing inner surface of the profile leg 118 of the guide rail rolls, below the track 126, i.e. in which directly to the Web section 116 of the guide rail adjoining below the area of the profile leg lying on the running rail 126 118. By the bias of the spring 138 Hollow profile section 130 in the sense of pivoting acted on by the profile leg 114 that the control roller 132 is held in contact with the profile leg 118.

The one attached to the end of the guide rail 112 inside the body Control section 136 is - corresponding to the vertical Arrangement of the pivot axis of the hollow profile section 130 so attached to the guide rail that he the desired Swiveling the hollow profile section in a horizontal Controls level in front of the rear wall of the drawer. For this the web section 116 of the guide rail sits in one curved in the direction of pivoting over approximately 90 ° continued section 116a, of which one inside the body Boundary edge a low stripe Material area 118a steps upwards, on which the Control roller 132 during the pivoting process of the Hollow section 130 rolls.

Opposite the profile leg 118 is the interior of the body strip-like material area 118a in height by held so low that the hollow section 130 over the upper boundary edge of the strip-shaped Swing material area 118a away and the inside of the body End of the actual running track 126 over the material area 118a pushed close to the rear wall of the body can be, from the upper free boundary edge this material region 118a in turn is a narrow strip-like one Material section 118b is folded, which the Control roller 132 still overlaps at the top and thus the function of the strip-shaped material section 35 of the Pull-out guide 10 takes over, i.e. a slipping of the control roller 132 from and from the strip-shaped section of material resulting malfunction prevented.

FIG. 7 also shows that in connection with the first exemplary embodiment slanted course explained as advantageous the parting plane between the one aligned rear end of the track 126 and the front End of the hollow profile section 130 by the illustrated oblique course of the dividing line visible in the figure T illustrated between these two parts.

FIG. 9 shows a modification of the first exemplary embodiment with a hollow profile section pivotable about a horizontal axis illustrated. The modification made relates the design of the guide rail 12 in Area of the control section, which here is a separately manufactured is flat component 36 made of plastic, which on End area on the inside of the flat side facing the drawer of the profile leg 14 of the guide rail 12 seated is attached. In the case shown, the Attachment so that in the manufacture of the control section 36 at which the profile leg 14 facing Several protruding plastic pins 86 are molded onto the flat side be when mounting on the guide rail through holes countersunk in the profile wall 14 inserted and then by pressing one on one about the softening temperature of the plastic material of the control section 36 heated ram under training one rivet head 88 into the countersink be deformed. Alternatively, there are other types of fastening, e.g. Rivet connections by means of separate aligned holes in the control section 36 and the profile leg 14 penetrating metallic rivets possible.

It can also be seen here that the control roller 32 and leading actual control curve on the profile leg 14 facing bottom side open or there only is closed by the profile leg 14. The steering role 32 is on the peripheral surface side by boundary walls 34 ', 34 "guided between their mutually facing surfaces the control roller 32 is inevitably guided, wherein against leakage towards the drawer by short, they laterally overlapping strip-shaped material sections 35 is secured.

The control section 36 can be made from plastic it also, the control roller 32 closer to the pivot axis to arrange the hollow profile section 30 on the running rail 26, the control curve then being recognizable in the drawing S-shaped course assumes. It has shown, that it is possible in this way to achieve a speedy and steady and noiseless passage of the rolling elements ensure in or out of the hollow profile section 30.

The hollow profile section in the first embodiment 30 biasing into the second swiveled position Spring is omitted in this embodiment, so that Hollow profile section 30 only when approaching the Drawer closed position positively guided in the control cam becomes. In all other extended positions of the running track the hollow profile section 30 becomes relative to the guide rail exclusively due to its own weight in the running track held in alignment. An unwanted one Swiveling up the hollow profile section 30, which leads to malfunctions is still not possible because the hollow profile section in the fully or partially extended position the track on the guide rail at Swing up the roller tracks on the guide rail side for the formed upper edge supporting the rolling elements of the profile leg 18 strikes the guide rail, i.e. cannot be pivoted further into a stable, swiveled-up position is.

Due to the omission of the hollow section 30 in the second pivoted up position bias spring is omitted in this embodiment, the additional function of automatic drawer retraction to the closed position. If such an automatic feed is desired, can here on known between the guide rail 12 and the Running track 26 effective automatic retraction become.
