DETAILED DESCRIPTION

(15) FIGS. 1 to 10 show a first exemplary embodiment of the corner cabinet 11 according to the invention.

(16) As shown in FIG. 6 in particular, the corner cabinet 11 has a cabinet carcass 12, which by way of example is shown with an L-shaped floor outline. The cabinet carcass 12 consists of a cabinet base 13, which by way of example is shown with an with L-shaped floor outline. As a rule, supporting feet are arranged on the underside of the cabinet base 13 which are if necessary height-adjustable in order to guarantee that the corner cabinet 11 stands without any play, even on an uneven floor surface. The intervening space between the underside of the cabinet base 13 and the floor surface within which the supporting feet are arranged is clad with a baseboard 14. The cabinet carcass 13 also possesses a rear wall 15 which for example consists of two rear wall parts 16a, 16b arranged at right angles relative to one another. As shown in FIG. 5 in particular, the two rear wall parts 16a, 16b preferably adjoin side walls 17, 18 arranged at right angles thereto.

(17) At the same time the side walls 17, 18 form side walls for left-hand and right-hand extensions of the cabinet carcass 12. In the example shown, a carcass component 19 with rectangular floor outline adjoins the carcass component of the cabinet carcass 12 with L-shaped floor outline on the left-hand side. The left-hand side wall 17 of the L-shaped carcass component thereby simultaneously forms the right-hand side wall of the further carcass component 19. A further carcass component 21 also adjoins the right-hand side wall 18 of the inner L-shaped carcass component 20 of the corner cabinet 11, so that the right-hand side wall 18 forms the left-hand side wall of the further carcass component 21.

(18) In the example shown, the right-hand further carcass component 21 is twice as large as the left-hand further carcass component 19. Naturally it is also possible for the dimensions of the further carcass components 19, 21 to be quite different, for example the left-hand carcass component could be larger than the right-hand one. It is also possible that the inner carcass component 20 with L-shaped floor outline forms the complete corner cabinet 11 and in this case further separate cabinets adjoin it on the left-hand and right-hand sides.

(19) The corner cabinet 11 also possesses an upper cabinet covering which by way of example is shown in the form of a work surface 22. As shown in FIG. 1 in particular, the work surface 22 is also L-shaped in form and extends over all the carcass components 19-21 of the corner cabinet 11.

(20) As in particular illustrated in FIG. 2, in relation to the inner carcass component 20, the L-shaped cabinet base 13, the two side walls 17, 18, the two rear wall parts 16a, 16b and the L-shaped section of the work surface 22 delimit an interior space 23. As also shown in FIG. 2, the outer edges of the side walls 17, 18, the outer edges of the L-shaped cabinet base 13 and lower edges of the L-shaped section of the work surface 22 delimit a door opening 24 which in the example shown has two opening sections 25a, 25b arranged at right angles relative to one another.

(21) The inner carcass component 20 is also associated with a corner cabinet door 26 mounted on the cabinet carcass 12 so as to swivel between a closed position 27 in which the door opening 24 is closed (FIG. 1) and an open position 28 which allows access to the interior space 23 of the cabinet carcass 12 (FIG. 2).

(22) The corner cabinet door 26 is designed as a folding door, with a first door element 29 which is mounted on the cabinet carcass 12 in the vicinity of the door opening 24 by means of a door bearing device 30 and with a second door element 31 which is mounted swivelably on the first door element 29 via swivel bearing means 32. The door bearing device 30 by means of which the first door element 29 is swivelably mounted is located in the region of the right-hand opening section 25a and in the region of the right-hand side wall 18. The door bearing device 30 comprises two hinges (not shown) which are fixed, on the one hand, to the side of the side wall 18 facing the interior space 23 and on the other hand to the inner side 33 of the first door element 29.

(23) The second door element 31 is, as mentioned, mounted swivelably on the first door element 29 via the swivel bearing means 32. In the example shown, as shown in FIGS. 4, 8 and 9 in particular, the swivel bearing means 32 comprise at least one hinge 34 connecting the two door elements 29, 31 swivelably with one another, in particular two hinges 34a, 34b, of which a first hinge 34a is arranged in the upper region of the two door elements 29, 31 and a second hinge 34b is arranged in the lower region of the two door elements 29, 31. The hinges 34a, 34b each possess a first hinge part 35 fixed on the first door element 29 and a second hinge part 36 fixed on the second door element 31 which are connected with one another in an articulated manner via at least one articulated joint. In the example shown, the two hinge parts 35, 36 are designed in the form of a hinge cup and a hinge arm, wherein, as shown in FIG. 4 in particular, according to a first exemplary embodiment the hinge cup is fixed to the first door element 29 and the hinge arm is fixed to the second door element 31.

(24) As shown in FIG. 9 in particular, the hinge arm associated with the second door element 31 possesses a fixing section 37, which is fixed onto the inner side 38 of the second door element. Connected in a single piece with the fixing section 37, an arm section 39 is provided which bridges a joint 40 between the two door elements 29, 31 and points in the direction of the hinge cup. The arm section 39 projects at an angle from the associated fixing section 37 and is oriented at an angle in the direction of outer sides 41, 42 of the two door elements 29, 31.

(25) As also shown in FIG. 9, the hinge cup possesses a cup section 43 which is fitted in a cup-like recess 44 in the inner side 38 of the first door element 29. In addition to the cup section 43 the hinge cup also possesses a mounting plate 45 for mounting on the inner side 33 of the first door element. The mounting plate 45 possesses for example two mounting holes via which fixing screws can be screwed into the material of the first door element 29.

(26) The cup section 43 of the hinge cup possesses a cup opening 46 bounded by a cup wall 47 which is limited on the underside by a cup bottom. A lever 48 connecting a hinge cup and hinge arm with one another is also provided which on the one hand is mounted in an articulated manner on the hinge cup and on the other hand is mounted in an articulated manner on the hinge arm, in particular on its arm section 39. The cup-side mounting of the lever 48 can for example be located within the region of the cup wall 47. The lever 48 can for example have a bearing pin (not shown) which projects to the left and right of the lever 48 and is mounted rotatably in openings in opposite wall sections of the cup wall 47.

(27) A swivel angle limiting device 49 acting between the two door elements 29, 31 is provided by means of which the swiveling range of the two door elements 29, 31 relative to one another is limited to a maximum external angle which lies within the range from 45 to 180.

(28) In the example shown, the two opening sections 25a, 25b of the door opening 24 are oriented at an angle of 90 relative to one another. Therefore, in the closed position 27 the two door elements 29, 31 assume an external angle which amounts to 90.

(29) The swivel angle limiting device 49 possesses a stop surface 50 formed on the first or second hinge part 35, 36, i.e. on the hinge arm or on the hinge cup, for a corresponding stop 51 formed for this purpose on the second and first hinge part 36, 35, i.e. the hinge arm or hinge cup, which on swiveling of the two door elements 29, 31 impinges on the associated stop surface 50.

(30) As shown in FIGS. 11 to 13 in particular, according to the second exemplary embodiment of the corner cabinet 11 according to the invention the stop surface 50 is arranged on the cup wall 47 of the hinge cup and, from the cup base, is oriented facing obliquely away from the hinge arm. In contrast, the stop 51 is formed by an adjustment screw 52 which is part of an adjustment device 53.

(31) The adjustment screw 52 is arranged on the free end of the arm section 39 of the hinge arm. On the arm section 39 there is a threaded bore 54 with an inner thread which interacts with an outer thread formed on a screw shaft of the adjustment screw. As shown in FIG. 13 in particular, the greatest part of the adjustment screw 52 projects downwards from the threaded bore 54, this projecting part forming the stop 51. The screw head of the adjustment screw 52 is equipped with an engagement structure for engagement of an operating tool, in particular a screwdriver. A cross-slot structure is illustrated by way of example.

(32) As already mentioned, the part of the screw shaft 55 projecting downwards from the threaded bore 54 forms the adjustment screw 52 of the stop 51, wherein a surface section 56 of the screw shaft 55 can be brought into contact with the sloping stop surface 50 on the cup wall 47. The impingement of the stop 51, i.e. of the surface section 56, on the sloping stop surface 50 defines the maximum external angle .

(33) Since the depth of penetration of the adjustment screw 52 within the threaded bore 54 is variable, the maximum external angle can be changed, wherein in the specific case unscrewing the adjustment screw from the threaded bore 54 produces an enlargement of the maximum external angle . Conversely, the maximum external angle can be reduced by screwing the adjustment screw 52 into the threaded bore 54.

(34) FIGS. 1 to 10 show a first exemplary embodiment of the corner cabinet 11 according to the invention in which the swivel angle limiting device is not, as in the second exemplary embodiment described above, associated with the swivel bearing means, i.e. the hinges 34a, 34b, but is formed separately from the swivel bearing means, i.e. the hinges 34a, 34b.

(35) According to a first exemplary embodiment, the swivel angle limiting device 49 comprises at least one angle piece 57 which has an in particular plate-like mounting section 58 by means of which the angle piece 57 is fixed to the inner side of the first door element 29.

(36) As shown in FIG. 9 in particular, the angle piece also possesses a stop section 59 which is in particular formed in a single piece with the mounting section 58 and projects from this at an angle. The stop section 59 serves as a stop for the second door element and bridges the joint 40 between the two door elements 29, 31, wherein the free end terminates with a stop surface 60 within the region of the inner side 38 of the second door element 31.

(37) As shown in FIG. 9 in particular, the angle piece 57 is located approximately in the centre between the two hinges 34a, 34b. The angle piece 57 is a relatively economical retrofit component, so that corner cabinet doors 26 equipped with conventional hinges can be retrofitted with a swivel angle limiting device 49.

(38) The corner cabinet also comprises a control device 61 for controlling the movement of the corner cabinet door 26. The control device possesses a base part 62 fixed to the cabinet carcass 12 on the cabinet base 13 within the region of the left-hand second opening section 25b and a control part 63 which is mounted on the base part 62 so as to be moveable between an inner position 64 and an outer position 65 in which it projects beyond the plane of the door opening 24. In the example shown, the control part 63 is a control arm which is mounted on the base part 62 so as to be swivelable around an arm swivel axis 67 spaced at a distance from the door swivel axis 66.

(39) The control part 63 can be coupled with the second door element 31 when closing and uncoupled when opening by means of coupling means, such that it controls the movement of the second door element 31 at the end of the closing phase and at the beginning of the opening phase. The control device 61 possesses locking means (not shown) by means of which the control part 63 is locked in position in its outer position 65 with uncoupled second door element, wherein the locking means are designed such that on coupling the second door element 31 and control part 63 a release of the locking takes place enabling swiveling of the control part 63.

(40) The control part possesses on its outer side 68 a stop surface 69 for the second door element 31 which is active in the locked outer position 65.

(41) As shown in FIG. 1 in particular, a door handle 70 is arranged on the outer side 42 of the second door element 31. The outer carcass components 19, 21 surrounding the inner carcass component 20 each possess a cabinet door 71 which is not designed in the form of a folding door, wherein door handles 73 are also arranged on the outer sides 72 of the cabinet doors 71.

(42) The corner cabinet door 26 is initially in the closed position 27 illustrated in FIG. 1. The outer sides 41, 42 of the two door elements 29, 31 thereby enclose an external angle which amounts to 90. In order to open the corner cabinet door 26, the user grasps the door handle 70 formed on the second door element and pulls the second door element 31 in their direction. The whole corner cabinet door thereby swivels around the door swivel axis 66. At the beginning of the opening phase, the second door element 31 is controlled by the control device 61, as a result of which the control part 63 swings out of the plane of the door opening 24. After a certain opening travel, the control part 63 and second door element 31 are uncoupled. The corner cabinet door 26 can now be swivelled open further, wherein the external angle assumed in the inner position is variable.

(43) As shown in FIG. 2 in particular, the swivel angle limiting device 49 prevents the second door element 31 from being able to swivel around the first door element 29 within a large angular range. In the example shown, the maximum external angle is limited to approx. 125. Thus, if the external angle is increased when opening the door, this is only possible up to approx. 125. Once this angle is reached, the inner side 38 of the second door element 31 impinges against the stop surface 60 on the stop section 59 of the angle piece 57. This situation is shown, by way of example, in FIG. 2.

(44) When closing the corner cabinet door 26, the whole corner cabinet door 26 initially swivels inwards around the door swivel axis 66. As shown in FIG. 6 in particular, the inner side 38 of the second door element 31 then initially impinges against the stop surface 69 on the outer side 68 of the control part 63 of the control device 61. This prevents the inner side 38 of the second door element 31 from colliding with the door handle 73 of the cabinet door 71 of the carcass component 19 arranged to the left of the inner carcass component 20. This prevents damage to this door handle.

(45) On further closing, the movement of the second door element 31 is controlled by means of the control part 63. Finally, the corner cabinet door 26a reaches the closed position 27, in which the control part 63 coupled to the second door element 31 is located in its inner position 64.
