It presses the claw 26 consequently into its first position shown in
(31)
(32) As shown in
(33) A portion of the damper 60 is inserted into the centering region 31 through an opening 35. In the exemplary embodiment shown, a movably mounted cylinder 61 of a linear damper is inserted into the centering region 31. The cylinder 61 comprises an inclination 62 on the end face.
(34) A second spring 38 is also arranged outside the hinge cup. It is guided through the opening 35 into the centering region 31 by way of its free ends 38.2. The second spring 38, realized as a leg spring, comprises a winding 38.3 and a second spring clip 38.1.
(35) The centering region 31 is formed by cup side walls 31.2, a rounding portion 31.4 as well as a cup bottom 31.1. Joint receiving means 31.3 in the form of bores are provided in the opposite cup side walls 31.2. The joint receiving means 31.3 have assigned thereto an articulation bolt 39 with an end-face stop portion 39.1.
(36) The hinge arm 40 comprises an articulated lever 43. A bolt receiving means 41 is integrally molded onto the end of the articulated lever 43 facing the hinge cup 30.
(37) The bolt receiving means 41 is realized as a cylindrically curved end region of the articulated lever 43. Two guide curves 42 are arranged on the articulated lever 43 on opposite sides in the region of the bolt receiving means 41.
(38) The articulated lever 43 is connected in one piece to a mounting portion 44 of the hinge arm 40. The mounting portion 44 is preferably realized as a punched part. It comprises side regions 44.2 which are angled at the side toward the connection element 50. These form guides 44.1 which are aligned in the direction of the longitudinal extension of the hinge arm 40. A thread receiving means 45, a recess 46 and a fourth elongated hole 47 are provided in the mounting portion 44.
(39) The connection element 50 is arranged opposite to the mounting portion 44 of the hinge arm 40. It comprises a flat basic body 51. A through-opening 53 is provided in the basic body 51. The through-opening 53 is arranged so as to be flush with the recess 43 of the mounting portion 44 of the hinge arm 40. An adjusting element receiving means 57, in the form of a slot which extends from the edge of the connection element 50, is provided in the basic body 51 pointing toward the articulated lever 43 of the hinge arm 40. The adjusting element receiving means 57 is arranged opposite to the thread receiving means 45 of the mounting portion 44 of the hinge arm 40. Congruently to the fourth elongated hole 47 of the mounting portion 44, a flap 52 with a bore 52.1 is formed out of the plane of the basic body 51 of the connection element 50. The flap 52, in this case, is raised in the direction of the mounting portion 44 above the surface of the basic body 51. It is aligned at least approximately parallel to the surface of the basic body 51 in the region of the bore 52.1. The basic body 51 of the connection element 50 is closed off at the end by way of a holding portion 51.1. The holding portion 51.1 is consequently formed by a front edge of the connection element 50. It is arranged opposite to the adjusting element receiving means 57.
(40) Proceeding from the side of the mounting portion 44 facing the articulated lever 43, two hooks 56 are integrally molded on the sides of the connection element 50. The hooks 56 are angled in relation to the surface of the basic body 51. They point in the direction remote from the mounting portion 44. The hooks 56 are open in the direction of the holding portion 51.1 of the connection element 50. Two guide flaps 55, connected to the hooks 56 and situated opposite one another, are angled out of the plane of the basic body 51 in the direction of the mounting portion 44 of the hinge arm 40. The distance between the guide flaps 55 is less than the distance between the side regions 44.2 of the mounting portion 44. Two holding flaps 54, which are arranged opposite one another, are subsequently integrally molded on the sides of the basic body 51 and are angled toward the side of the basic body 51 remote from the mounting portion 44 of the hinge arm 40.
(41) The hinge body 7 has assigned thereto a second eccentric 58. The design of the second eccentric 58 corresponds to that of the first eccentric 27. It comprises accordingly a second tool receiving means 58.1, a second guide region 58.2 and a second eccentric cam 58.3.
(42) In addition, the hinge body 7 has assigned thereto an adjusting screw 59 with a third tool receiving means 59.1, a thread 59.2, a groove 59.3 and a closure 59.4.
(43)
(44) The mounting portion 44 of the hinge arm 40 is connected to the connection element 50, as is described in more detail with regard to
(45)
(46) The adjustment screw 59 is screwed into the thread receiving means 45 on the mounting portion 44 of the hinge arm 40 by way of its thread 59.2 and is rotatably mounted at the end of the adjustment element receiving means 57 of the connection element 50. The holding portion 51.1, as an edge of the basic body 51 of the connection element 50 remote from the articulated lever 43, closes off with the mounting portion 44 of the hinge arm 40. It is arranged, in this case, at a spacing from the mounting portion 44 and between the two side regions 44.2 integrally molded thereon.
(47)
(48) The articulated lever 43 is pivotably mounted on the hinge cup 30 inside the centering region 31. It connects the hinge cup 30 to the mounting portion 44. The articulated lever 43 is connected in one piece to the mounting portion 44. Proceeding from the outer contact surface 32, the centering region 31 forms an indentation. The mounting region 34 also realizes such an indentation. In this case, the cup depth in the mounting region 34 is smaller than in the centering region 41. The mounting region 34 is closed off by a cup bottom. The damper 60 is attached from the outside to the cup bottom of the mounting region 34. The damper 60 is mounted in the housing 70 for this purpose. The housing 70 is fastened to the cup bottom of the mounting region 34. A housing bottom 71 is preferably arranged in the same plane as the cup bottom of the centering region 31. The damper 60 is realized as a linear damper, preferably as a hydraulic linear damper. The cylinder 61 of the damper 60 is guided in a linearly movable manner in the housing 70. The end-face inclination 62 on the cylinder 61 of the damper 60 is guided into the centering region 31 of the hinge cup 30. The inclination 62 of the movably mounted cylinder 61 of the damper 60 consequently lies in the adjustment region of the articulated lever 43. Located opposite, a piston 63 of the damper 60 is fixed to a side wall of the housing 70. When closing the furniture hinge 1, the articulated lever 43 presses against the inclination 62 of the cylinder 61 and displaces it in the direction of the piston 63. As a result, the movement of the articulated lever 43 and consequently the closing movement of the furniture hinge 1 are damped.
(49) A spring receiving means 72 is attached to the housing 70. The spring receiving means 72 is realized as a groove in the housing wall. The second spring clip 38.1 of the second spring 38 is fixed in the spring receiving means 72. The second spring 38 is accordingly mounted on the housing 70 from the outside. The housing 70 consequently carries the damper 60 and the second spring 38. It can be fastened as a structural unit to the bottom of the mounting region 34 of the hinge cup 30. The free ends 38.2 of the second spring 38 are guided through the opening 35 into the centering region 31 of the hinge cup 30. They abut against the guide curves 42 on the articulated lever 43 and each support, from a certain opening angle, the opening or closing operation of the furniture hinge 1.
(50) The adjustment screw 59 is screwed into the thread receiving means 45 on the mounting portion 44 of the hinge arm. The groove 59.3 is arranged in the adjustment element receiving means 57 of the connection element 50 and is held axially by the closure 59.4, the cross section of which is enlarged compared to that of the groove 59.3. The adjustment screw 59 consequently connects the hinge arm 40 to the connection element 50. The distance between the connection element 50 and the hinge arm 40 can be adjusted by means of the adjustment screw 59. The furniture door 5 can consequently be adjusted corresponding to
(51) The second eccentric 58 is guided by way of its guide region 58 in the fourth elongated hole 47 on the hinge arm 40. At the same time, the second eccentric 58 is fixed axially in the bore 52.1 of the flap 52 on the connection element 50. The second eccentric 58 consequently also connects the connection element 50 to the hinge arm 40. As a result of rotating the second eccentric, the hinge arm 40 is adjusted in relation to the connection element 50. The furniture door 5 is consequently displaced along the x axis 8.1 according to
(52) At the end the connection element 50 closes off flush by way of its holding portion 51.1 with the mounting portion 44 of the hinge arm 40. The holding portion 51.1 thus realizes an edge that is accessible from the outside.
(53) The hooks 56 are integrally molded on the connection element 50 on the side facing the articulated lever 43. The openings of the hooks 56, in this case, are aligned in the direction of the holding portion 51.1.
(54)
(55) To connect the hinge body 7 to the mounting plate 6, the hooks 56 are suspended in the hook receiving means 22.3. The mounting region 44 of the hinge arm 40 is then rotated about the hook receiving means 22.3 with the connected connection plate 50. As a result, the holding flaps 54 are inserted into the assigned guide slots 22.2. The connection element 50 presses by way of its holding portion 51.1 onto the run-up slope 26.5 of the claw 26. As a result, the claw 26 is rotated about the spindle 24 in opposition to the acting spring force. In this case, the claw opening 26.3 is aligned in the direction of the abutting holding portion 51.1 of the connection element 50. The claw 26 is rotated until the holding portion 51.1 slides into the claw opening 26.3. When there is not any pressure exerted onto the run-up slope 26.5, the claw 26 is adjusted into its first position again. As a result, it encompasses the holding portion 51.1. The hinge arm 30 is consequently blocked by the hooks 56 in one direction along the longitudinal extension of the furniture hinge 1 and by the claw 26 in the opposite direction. On account of the blocking by the claw 26, the hooks 56 are not able to slide out of the hook receiving means 22.3. This prevents the hinge arm 40 coming free from the mounting plate 6. In the lateral direction, the hinge arm 40 is blocked in relation to the mounting plate 6 by the hooks 56 and the holding flaps 54 received in the guide slots 22.2.
(56) A connection system, which is able to be closed without the use of a tool, is created by the claw 26 and the hooks 56 in combination with the holding portion 51.1 and the hook receiving means 22.3. This is effected simply as a result of the hooks 56 being hooked into the hook receiving means 22.3 and then the mounting portion 44 being pressed onto the mounting plate 6. The claw 26, as the provided blocking element, is adjusted from a first into a second position as a result of said mounting movement. In said second position, the holding portion 51.1 can be inserted into the claw opening 26.3. The spring 25 then adjusts the claw 26 into it first position again in which the hinge arm 40 or the connection element 50 fixed to the hinge arm 40 is fixed to the mounting plate 6. The connection system may also be referred to as a releasable connector.
(57) For fastening the hinge arm 40 to the mounting plate 6, the claw 26 as the connection element can also be adjusted manually from its first into the second position. The web 26.2 forms a suitable control element for this purpose.
(58) For releasing the connection between the hinge body 7 and the mounting plate 6, the claw 26 can be adjusted manually into its second position. As a result, the claw 26 releases the holding portion 51.1. The hooks 56 can then be hooked out of the hook receiving means 22.3 and the connection released. The connection system can accordingly also be released again without the use of a tool.
(59)
(60)
(61)
(62) It can easily be seen in the sectional representation shown that the holding portion 51.1 of the connection element 50 is fixed in the claw opening 26.3 of the claw 26 and consequently, in conjunction with the hooks 56, a movement of the hinge arm 40 in relation to the mounting plate 6 is blocked. As a result of pressure onto the claw 26 in the region of the web 26.2, said claw can be rotated about the spindle 24 in opposition to the spring force applied by the spring 25, clockwise in the present view. The holding portion 51.1 is released as a result. The hinge arm 40 can then be released from the mounting plate 6.
(63)
(64) For mounting the furniture door 5, the mounting plate 6 and the hinge body 7 are present in a separate manner. Both are premounted. First of all, the mounting plate 6 is aligned with the stop 14 on the frame 4. The mounting plate 6 is then screw-connected to the frame 4. The hinge cup 30 is inserted into the bore of the furniture door 5, aligned and screw-connected to the furniture door 5. Where multiple furniture hinges 1 are provided, they are mounted in a corresponding manner. The furniture door 5 is then held at the opening of the furniture carcass 2 and is aligned such that the mounting portion 44 of the hinge arm 40 lies above the assigned mounting plate 6. Said mounting position can be seen in particular in
(65) The furniture door 5 can be connected to the furniture carcass 3 quickly, simply and without the use of a tool as a result of the furniture hinge 1 according to the invention. By adjusting the claw 26 manually, the furniture door 5 can also be released from the furniture carcass 3 in a simple, quick and tool-free manner. The furniture hinge 1 can preferably be used for mounting on the frames (face frame) of items of furniture 2.
