Description

TECHNICAL FIELD OF THE INVENTION

The invention relates to a fitting for a corner cabinet with the features of the preamble of independent claim 1. Furthermore, the invention relates to a corner cabinet with such a fitting.

A corner cabinet is understood to mean in particular such a corner cabinet whose body defines a cuboidal interior, which is accessible only by a door opening extending over approximately half the width of the interior. In the body mounted trays can therefore be easily loaded and unloaded only if they can be moved out of the interior at least to a large extent through the door opening. The invention thus relates in particular to a fitting which allows such a movement of one or more as large as possible trays through the door opening.

WAS STANDING OF THE TECHNOLOGY

From the DE 77 11 111 U is a pivoting device for shelves or grates of corner cabinets known. The pivoting device consists of a support frame pivotally mounted at 90 ° on the center post of the corner cabinet in a horizontal plane. The intermediate floor or grate is arranged longitudinally displaceable on the support frame.

From the DE 37 30 832 A1 a rotary floor provided with an extracting device is known for a corner cabinet having the features of the preamble of independent claim 1. A carrier is pivotable about a vertical pivot axis to attach to the body of the corner cupboard. On the support rails are mounted to support the rotary bottom. By a coupling mechanism, the pivotal movement of the carrier with respect to the furniture body in such a way with the linear extension movement of the rotary bottom in Coupled with respect to the carrier that the rotary bottom in the extended position can not abut the carcass. The coupling mechanism is formed by a cam guide having a guide member to be fastened to the body and a guide member engaged therewith and mounted on the rotary bottom. The rotary-bottom side guide member is a cam groove formed on the underside of the rotary bottom, and the body-side guide member is a guide pin. The control groove has a circular arc-shaped portion, which merges at least at one end fluidly into a rectilinear, parallel to the rails extending portion. As a result, although the pivoting movement of the carrier and the linear extension movement of the rotary base merge into one another. Except for this transition region, however, they are so separated that the rotary bottom is either pivoted with the carrier about the vertical pivot axis or extended linearly.

From the EP 2 253 244 B1 a rotary and Ausziehbeschlag for a shelf in a corner cabinet is known, which is pivotable about a vertical pivot axis held in the corner cabinet carrier, an intermediate carrier which is pivotable about a pivot axis of the carrier parallel, but offset from this further pivot axis with respect to the carrier is, and has a pull-out on which the shelf relative to the intermediate carrier is linearly displaceable. In this case, the pivoting movement of the intermediate carrier is controlled relative to the carrier during the entire movement by a corpus fixed positive guide element. The positive guide element is a guide link, which is arranged on a console supporting the second pivot axis of the carrier and in which a seated on the intermediate carrier curve follower engages. The positive guide element is designed so that it prevents rotation of the intermediate carrier relative to the carrier in an initial phase of a pivoting movement, with which the shelf is swung out of the corner cabinet. In addition, the shelf is guided by a guide device directly on the carrier, which is designed so that it blocks a shift of the shelf relative to the intermediate carrier and the carrier in the initial phase of the pivoting movement. Furthermore, the guide means is designed so that in a final phase of the movement of the shelf, after it has been swung out of the corner cabinet, only a displacement of the shelf relative to the intermediate carrier and blocks rotation of the intermediate carrier relative to the carrier. Again, therefore, the pivotal movement and the extension of the shelf are superimposed only in a central transition region.

From the EP 1 616 503 A1 is a corner cabinet with a about a cabinet door about half front accessible, rectangular in plan ground interior known in which at least one one-piece tray supported by approximately semicircular basic shape and movable by means of a fitting from an inner position to an outer position in which the tray on the Level of the door opening of the corner cabinet protrudes forward. The fitting has an at least approximately vertical support column and two on the underside of the tray articulated attacking handlebar. The first link is pivotable about the next in the interior of the door opening in the support column and the second arm about an axis parallel to the support column axis of a support bearing, which is mounted near the door opening on the this limiting side wall of the corner cabinet. In this case, the tray performs a jointly controlled by two links movement in the transition from the inner position to the outer position and vice versa. In its outward position, the shelf is not only in front of the door opening, but it stands laterally away from the door and next to the corner cabinet on the door opening over. Therefore, there must be room for removing the tray into its outward position.

From the EP 2 092 850 A1 is a fitting for a corner cabinet for the movable guidance of at least one tray between an inner position in an interior of the corner cupboard and an outer position in which the tray protrudes at least partially beyond a plane of a door opening of the corner cupboard known. The fitting has a support arm pivotally mounted on the one hand to a pivot axis fixed in the installed state and on the other hand pivotally mounted on the associated tray to a shelf for Tablarabstützung and at least one control device for controlling the Tablarbewegung between the inner and the outer position. The control device has a first control single lever and a second control single lever, which are mounted on the one hand about a fixed hinge axis and on the other hand pivotable about a tablarfeste pivot axis. In this case, the two tablarfesten pivot axes are arranged with respect to the bearing point of the support arm on the same tray side. At the bearing the tray relative to the support arm is not only pivotally mounted but also linearly movable by means of a guide device. In other words, the pivot bearing of the tray is displaceable along the support arm. Alternatively, the support arm has two support arm parts articulated to one another via a connecting joint to realize a variable effective length of the support arm between its fixed pivot axis and the pivot axis between it and the shelf.

From the EP 2 064 971 A1 a fitting for a corner cabinet is known, which at least one tray between an inner position in an interior of the corner cupboard and an outdoor position in which the tray at least partially protrudes beyond a plane of a door opening of the corner cabinet, movably. The fitting has on the one hand to a pivotally mounted in its installed state stationary pivot axis and on the other hand mounted on a bearing pivotally mounted on the associated tray supporting arm for Tablarabstützung and a control device for controlling the Tablarbe movement between the inner and the outer position. The control device comprises a first multi-joint lever linkage and a second multi-joint lever linkage, which are each pivotally mounted on the one hand about a fixed in the installed state of the tray hinge axis and on the other hand to a tablarfeste pivot axis. The two pivot axes are arranged at a distance from each other, wherein the pivot axis of the first multi-joint lever linkage is arranged in the region of the bearing. In the area of the bearing, in which the support arm is mounted on the associated tray, the tray is rotatably supported on a guide sleeve, which is guided linearly movable on the support arm.

OBJECT OF THE INVENTION

The invention has for its object to provide a fitting with the features of the preamble of independent claim 1, in which a pivoting movement and a pull-out movement of the tray are superimposed to a harmonious overall movement with each other, the tray with a substantial part of its surface from the interior of the Eckschranks transferred in front of his door opening.

SOLUTION

The object of the invention is achieved by a fitting with the features of independent claim 1. Preferred embodiments of the fitting are described in the dependent claims 2 to 12. The claims 13 to 15 are directed to a corner cabinet with the fitting according to the invention.

DESCRIPTION OF THE INVENTION

In a fitting according to the invention for a corner cabinet with a fastening device for stationary mounting having base, a pivotally mounted about a first vertical pivot axis from a pivoted position to a pivoted position pivotally mounted on the base support arm, one longitudinally along a horizontal axis trained and in a pull-out movement along the axis from an inserted position to an extended position extendable to the support arm mounted tray and the pivotal movement of the support arm with the extension movement of the tray coupling coupling means, the coupling means on a link arm, which pivotable at its one end about a second vertical pivot axis is pivotally mounted on the tray at the base and at its other end about a third vertical pivot axis. In this case, the third pivot axis extends in a relation to the pull-out rear portion of the tray, and the second pivot axis is in the retracted position of the tray when viewed along the horizontal axis between the first pivot axis and the third pivot axis.

In particular, a distance between the first pivot axis and the second pivot axis in the retracted position of the tray, when viewed along the horizontal axis, 10 to 90%, preferably 20 to 80%, more preferably 30 to 70% or even 40 to 60% a distance between the first pivot axis and the third pivot axis. Accordingly, then a distance between the second pivot axis and the third pivot axis is 90 to 10%, preferably 80 to 20%, more preferably 70 to 30% or 60 to 40% of the distance between the first pivot axis and the third pivot axis.

In the fitting, the tray is supported in a proven manner on the support arm, against which it is linearly movable and which is pivotable relative to the stationary base of the fitting. The link arm of the coupling device is used exclusively for coupling the pivoting movement of the support arm and the pull-out movement of the tray. The second pivot axis about which the handlebar arm is pivotable relative to the base is, viewed in the retracted position of the tray in the direction of the horizontal axis, along which the tray is extendable relative to the support arm, farther back than the first vertical pivot axis to the Support arm is pivotable relative to the base. The third vertical pivot axis about which the link arm is pivotally mounted on the tray is attached this consideration even further back. The rear area of the tray, in which the third pivot axis extends, may even lie outside of a shelf of the tray. Then, the link arm is pivotally mounted about the third pivot axis on a rigid arm of the tray, which projects beyond the shelf of the tray to the rear. The link arm causes a complete superposition of the pull-out movement of the tray and the pivotal movement of the support arm, wherein the relative proportions, starting from the inserted position of the tray continuously move from the pivoting movement to the pull-out. In the opposite direction of movement of the tray in its retracted position, it is reversed.

In the fitting according to the invention, the link arm in each pivotal position about the second pivot axis relative to the base on a fixed length defined between the second pivot axis and the third pivot axis. This fixed length can be constant over all pivot positions about the second pivot axis relative to the base. Then the coupling device of the fitting according to the invention is particularly simple.

However, the link arm may also have a plurality of sub-arms which are pivotable relative to each other about further vertical pivot axes and a length which is realized thereby via its pivot positions about the second pivot axis relative to the base. With the help of the variable, but nonetheless for each pivotal position about the second pivot axis defined length of the link arm, the coupling device of the invention can also fitting a tray of maximum dimensions, d. H. maximum surface, safely pass through the door opening of the respective corner cupboard without hitting the corpus of the corner cupboard. In other words, with the aid of a variable length of the link arm, the area of the tray can be increased with the same dimensions of the corner cabinet with respect to a link arm of constant length.

In order to predetermine the length of the link arm depending on its pivotal position about the second pivot axis, a control bolt projecting vertically from a part arm of the link arm can engage in a horizontally extending, relative to the base or the tray stationary horizontal curved path. Preferably, the cam track in the base extends around the second pivot axis. For friction reduction between the control bolt and the Curved track can be mounted on the control pin, a guide roller over which the control bolt engages the edge of the cam track.

Specifically, the link arm may comprise three sub-arms, wherein two of the three arms are pivotally connected to each other via a horizontal slot in one of the two arms, while the other vertical pivot axes between the arms are fixed along the arms part. The partial arms can all be straight. In particular, the part of the arm with the slot can also be curved, and along this part of the arm extending slot may have a correspondingly curved course.

In another specific embodiment, the link arm has four sub-arms in a four-bar arrangement. In this case, the four sub-arms can be provided in a Parallellogrammlenkeranordnung, wherein at least one, often two of the sub-arms can survive on the formed between the four sub-arms four pivot axes to the outside.

In the fitting according to the invention, a tension spring may be attached to the base and the handlebar arm, that it acts on the tray when approaching its retracted position in this inserted position and when approaching its extended position in this extended position. The tension spring thus not only provides a self-closing mechanism for the tray, but also transfers the tray completely to its extended position and holds it there until it is deliberately pushed back in again.

Concretely, the tension spring in the retracted position of the tray on the side facing away from the tray of the second pivot axis and in the extended position of the tray on the tray facing side of the second pivot axis. That is, during the extension of the tray, the tension spring sweeps over the second pivot axis, thereby reaching its point of maximum elongation.

The base of the fitting according to the invention may comprise a vertical supporting column having the fastening means at its upper and lower ends. This support column can then be secured in the interior of the respective corner cabinet next to the door opening.

The base may further comprise a base on which the support arm is pivotably mounted and which is mounted in principle rigid but adjustable in height on the support column. In this case, several pedestals for several trays can be stored one above the other on the support column.

The support column can be viewed in the retracted position of the tray along the horizontal axis between the first and the second pivot axis. This is the first pivot axis about which the support arm is pivotable, seen from the support column in the extension direction, while the second pivot axis is further back in the cabinet interior.

Furthermore, in the retracted position of the tray, the support column may be located on one side of a vertical plane defined by the first pivot axis and the second pivot axis, while a linear guide disposed between the support arm and the tray is on the other side of this vertical plane. The tray itself may extend in its retracted position over the plane spanned by the first and second pivot axis plane, so that the support arm and the arm are stored below the tray on the base.

A corner cabinet according to the invention with a carcass, a cuboidal interior defined by the carcass and a door opening which extends over only a part of a width of the interior has a fitting according to the invention attached to the carcass with its base.

The base is preferably not secured in a region of the interior space located behind the door opening, but in an adjacent region of the interior space on the carcass. The first vertical pivot axis about which the support arm is pivotally mounted on the base, however, preferably passes through the area behind the door opening of the interior of the corner cupboard.

Typically, the corner cabinet will have a hinged cabinet door pivoting about a vertical door pivot axis extending in the area of the front cabinet center. At the cabinet door and the tray, with several trays to the bottom shelf, an at least zugsteifes coupling element can be hinged. By this coupling element, the tray can be moved out of the interior of the corner cupboard when swinging the cabinet door, while the cabinet door is swung back when moving the tray into the interior of the coupling element. The multi-joint arrangement, which is formed by the door, the coupling element and the support arm of the base mounted tray is, even if the coupling element is not only zugsteif, but also pressure-resistant, not fully defined. The coupling element therefore does not replace the link arm of the fitting according to the invention. If several trays are provided, as already indicated, only the lowest with the cabinet door can be moved out of the interior. Then objects placed on it are accessible. An arranged above it further tray can, if necessary, separately from the interior of the corner cabinet heraus- and be moved back into this.

DESCRIPTION OF THE FIGURES

The in Fig. 1 shown fitting 1 comprises a base 2 for fixed attachment by means of fastening screws 3. On the base 2, a support arm 4 is a first vertical Swivel axis 5 pivotally mounted. In this case, bearing pin 6 of the support arm 4 engage in bearing bushes 7, which are used in bearing lugs 8 of the base 2. On the support arm 4, the stationary parts of two mutually parallel slide rails 9 are attached. At the moving parts of the slide rails 9 longitudinal struts 10 are fixed, which are fixed to the underside of a shelf 11. The tray 11 is formed along a horizontal axis 49 stretched and extendable in the direction of this horizontal axis 49 by means of the slide rails 9 relative to the support arm 4, while the support arm 4 about the vertical pivot axis 5 relative to the base 2 is pivotable. The pull-out movement of the tray 11 and the pivotal movement of the support arm 4 are coupled together by a link arm 12. The link arm 12 is pivotally mounted about a second vertical pivot axis 13 on the base 2, wherein a bearing pin 14 of the link arm 12 engages in a pivot bushing 15 which is inserted into a bearing lug 16 of the base 2. At its other end, the link arm 12 is pivotable about a third vertical pivot axis 17 in a rear area 18 of the tray 11, which area is in the pull-out direction along the axis 49, here mounted on the underside of the tray 11. For this purpose, a bearing plate 19 is screwed by means of fastening screws 20 from below to the tray 11. In addition, a stop buffer 21 is fixed with a screw 22 on the underside of the tray 11, with which the tray strikes in its maximum extended position for damping its end stop on the support arm 4. Another stop buffer 50 is provided on the base 2. The handlebar arm 12 abuts on it when the tray 11 reaches its maximum inserted position. A coupling element 51 is pivotable about another vertical pivot axis via a bearing plate 52 on the underside of the tray 11 and mounted on a bracket 53.

Fig. 2 schematically shows the fitting 1 according to Fig. 1 installed in a corner cabinet 23 with a cuboidal interior 24 bounding body 25. The body 25 leaves a door opening 26 free, which is closable with a cabinet door 27 which can be pivoted about a near a center post 28 of the corner cabinet 23 extending vertical door pivot axis. Through the door opening 26 through the tray 11, of which only its peripheral edge is shown here, to show the parts lying below it of the fitting 1, to a substantial extent from the interior 24 of the corner cup 23 movable out. This facilitates the loading and unloading of the tray 11th Fig. 2 (a) shows the tray 11 in its maximum position opposite the support arm 4 inserted position and correspondingly in the maximum pivoted position of the support arm 4 relative to the base second Fig. 2 (d) shows, however, the maximum relative to the support arm 4 extended tray 11 and Accordingly, the maximum compared to the base 2 swung support arm 4. Die Fig. 2 (b) and (C) show intermediate positions and document that the extension movement of the tray 11 relative to the support arm 4 is coupled by the link arm 12 with the pivotal movement of the support arm 4 relative to the base 2. Furthermore, from the episode of Fig. 2 (a) to (d) to see how the arrangement of the vertical pivot axes 5, 13 and 17 changed during the movement of the tray 11 from the corner cabinet 23 out. In the retracted position of the tray 11 according to Fig. 2 (a) Contrary to the withdrawal direction of the tray 11 along the axis 49 is the second vertical pivot axis 13 further back and the third vertical pivot axis even further back in the region of the interior 24 next the door opening 26. The second vertical pivot axis 13 is at a horizontal distance from the first vertical pivot axis 5, which is slightly less than half the horizontal distance between the third vertical pivot axis 17 and the first vertical pivot axis 5. When the pull-out movement of the tray 11, the third vertical pivot axis 17 moves on a circular path about the second vertical pivot axis 13 to the first vertical pivot axis 5. In this case, however, the sequence of vertical pivot axes 5, 13 and 17 is maintained in the extraction direction along the rail 9, ie, the first vertical pivot axis 5 is in the pull-out furthest forward and the third vertical pivot axis 17 is located furthest back. By the coupling element 51, the console 53 is attached to the cabinet door 27, wherein in Fig. 2 (a) to (c) the corresponding position of the door 27 is indicated by an additional dashed line 27 ', the movement of the tray 11 from the interior 24 of the corner cabinet 23 is coupled to the pivotal movement of the cabinet door 27 about its door pivot axis near the center post 28. With the help of the coupling element, the tray 11 is pulled out of the interior 24 when opening the cabinet door 27. Conversely, when reinserting the tray 11 in the interior 24, the cabinet door 27 is pivoted back in front of the door opening 26. The coupling element 51 is at least zugsteif, but preferably designed as a pressure-resistant handlebars.

The in Fig. 3 The fitting 1 shown in a perspective view from below differs from that according to FIG Fig. 1 by a base 2 with a support plate 29 having a lower fastening plate 30 and an upper fastening device 56 and with a base 31 which is height adjustable on the support column 29 and on which the support arm 4 is pivotably mounted about the first vertical pivot axis 5. On the base 31 is also the Bar arm 12 about the second vertical pivot axis 13 pivotally mounted. The link arm 12 is here formed in three parts and has in this way a variable length between the second vertical pivot axis 13 and the third vertical pivot axis 17. However, the length of the link arm 12 is firmly defined for each pivotal position of the link arm 12 about the second vertical pivot axis 13 relative to the base 2. Immediately mounted pivotally about the vertical pivot axis 13 is a partial arm 32. With its vertical pivot axis 13 facing away from the lower arm 32 engages in a slot 33 in a partial arm 34, so that a further vertical pivot axis between the partial arms 32 and 34 along the Langloch's 33 variable position. The slot 33 terminates in front of the here formed between the arm 34 and a boom 35 of the tray 11 vertical pivot axis 17. On the boom 35, the vertical pivot axis 17 is also in the rear area 18 of the tray 11, although outside the edged shelf of the tray 11. At the opposite end of the third vertical pivot axis 17 of the partial arm 34, a partial arm 36 is articulated pivotably about a further pivot axis. The partial arm 36 engages with a guide roller 37 in a horizontal guide track 38. The guide roller 37 is arranged on a guide pin, not visible here, which protrudes vertically in the middle region of the partial arm 36. With its end remote from the partial arm 34, the partial arm 36 engages between the second vertical pivot axis 13 and the oblong hole 33 on the partial arm 32. The course of the cam tracks 38 about the second vertical pivot axis 13 controls the length of the link arm 12 in its pivotal movement about the second vertical pivot axis 13 relative to the base 2. The end of the partial arm 32 facing away from the second vertical pivot axis 13 moves along the slot 33. At both ends of the pivotal movement of the link arm 12 bumpers 54 and 55 are provided, in which the sub-arm 32 abuts. From the base 2, ie a member 41 which is fixed to the base 31 and in which the cam track 38 is formed, a tension spring 48 engages the arm 34. The tension spring 48 acts on the arm 12 in his in Fig. 3 shown position corresponding to the retracted position of the tray 11, and thus serves as a self-closing in this position. When pivoting the link arm 12 about the second vertical pivot axis 13, the tension spring 48 passes over the second vertical pivot axis 13, wherein it reaches its maximum extent. Thereafter, it acts on the handlebar arm 12 in its maximum about the second vertical pivot axis 13 pivoted position corresponding to the maximum extended position of the tray 11. The tension spring 48 thus transfers the tray 11 to its two end positions and holds it therein.

Fig. 4 shows the resulting movement of the tray 11, of which also only its peripheral edge is shown, with respect to the base 2 and thus out of the corner cabinet 23 out. At the end of the movement according to Fig. 4 (d) are the vertical pivot axes 5, 13 and 17 along the axis 49, ie, the predetermined by the pull-9 slides pull-out of the tray 11, almost together. Also transverse to the axis 49, the third vertical pivot axis 17 is close to the first vertical pivot axis 5. Thus, the tray 11 reaches a far before the door opening 26 lying extended position. In addition, the tray 11 has a compared with the tray 11 according to the Fig. 1 and 2 based on the base of the corner cup 23 larger area.

The fitting 1, which in the perspective exploded view according to Fig. 5 is different from the fitting 1 according to the Fig. 3 and 4 In addition, details of the mounting of the support arm 4 to the base 31 via a bearing pin 39 and washers 40 can be seen and that the element 41 of the base 2, in which the cam track 38 is formed separately manufactured and to the socket 31 is fixed. The link arm 12 here comprises a Parallellogrammlenkeranordnung 42 with four partial arms 43 to 46. A first short arm part 43 is mounted centrally about the second vertical pivot axis 13 pivotally. At its two ends, two mutually parallel partial arms 44 and 45 are mounted pivotably about further vertical pivot axes. In this case, the one arm 44 is not only in the direction of the fourth arm 46 via the arm 43, but also in the opposite direction, where it engages with its control pin 47 and the guide roller 37 arranged thereon in the guideway 38. The partial arm 46, which is parallel to the partial arm 43, projects from the vertical pivot axis relative to the partial arm 44 via the vertical pivot axis relative to the partial arm 45, until it reaches the rear panel 18 in the rear area 18 on the underside of the shelf 11 about the third vertical pivot axis 17 is pivotally mounted. Also, this link arm 12 has a variable, but for each pivotal position of the link arm 12 about the second vertical pivot axis 13 relative to the base 2 firmly defined length. With appropriate coordination of the course of the cam track 38 is a with the Ausziehweg, the in Fig. 4 is shown, very similar pull-out of the tray 11 according to Fig. 6 realized from the corner cabinet 23. Also, the size of the area of the tray 11, of which also in Fig. 6 only its peripheral edge is shown, compared to the base of the corner cup 23 as large as in Fig. 4 be shown. As in Fig. 4 is also in Fig. 6 shown that the base 2 is mounted with the support column 29 adjacent to the center post 28 of the corner cabinet 2, on the side facing away from the door opening 26 of the center post 28th
