DETAILED DESCRIPTION
(10)
(11) An adjustment element 40 is disposed within the assembly region 34. A setting head 41 of the adjustment element 40 is accessible from the open side of the hinge boss 30. Using a corresponding tool, said adjustment element 40 can be rotated by way of a crossed slot 46 that is incorporated in the adjustment head 41. A first and a second marking notch 37.3, 37.4 are incorporated in the base 34.1 of the assembly region 34. A marking 47 that is applied to the setting head 41 indicates the setting of the adjustment element 40 in relation to the marking notches 37.3, 37.4.
(12) By way of the free ends thereof, a spring 24 is guided from the assembly region 34 into the centering region 31. The free ends of the spring 24 bear on guide curves 23.2 which are attached to the articulated lever 23. One portion of the damper 60 is introduced into the centering portion 31 and protrudes into the adjustment travel of the articulated lever 23. The adjustment travel of the articulated lever 23 may also be referred to as a path of pivotal movement of the articulated lever 23 relative to the hinge boss 30. A movably mounted cylinder 62 of a linear damper is introduced into the central portion 31 in the exemplary embodiment shown.
(13) On account of the furniture hinge 20, the door 11 can be opened and closed in relation to a carcass of the item of furniture 10 of which only part of the frame 12 is shown. The door 11 is preferably connected to the frame 12, or to the carcass of the item of furniture 10, respectively, by way of two or a plurality of furniture hinges 20.
(14) The spring 24 facilitates the closing procedure of the door 11, and in the exemplary embodiment shown also facilitates the opening procedure of the door 11. To this end, the free ends of the spring 24 press against the guide curves 23.2. The latter are connected to the articulated lever 23 and are shaped in such a manner that said free ends by way of the spring compression open the furniture hinge 20 from a specific opening angle to the open position of said furniture hinge 20, and from a specific closing angle presses said furniture hinge 20 to the closed position of the latter.
(15) When the door 11 is being closed, the hinge boss 30 pivots about a rotation axis at the end of the articulated lever 23, said rotation axis being in the centering region 31. The spacing between the articulated lever 23 and the cylinder 62 of the damper 60 that has been introduced into the adjustment travel of the articulated lever 23 is reduced herein. The articulated lever 23 impacts the cylinder 62 before the closed position of the door 11 is achieved. Said cylinder 62, counter to the damping effect of the damper 60, is adjusted by the articulated lever 23. On account thereof, the movement of the door 11 is damped before the latter impacts the carcass or the frame 12, respectively. At the same time, the spring 24 by way of the guide curves 23.2 presses the door 11 to the closed position of the latter. The door 11 is thus completely closed in one damped movement.
(16) The adjustment element 40 enables the cylinder 62 to be blocked in the retracted position of the latter. The cylinder 62 in this instance is no longer guided into the adjustment travel of the articulated lever 23, such that no damping is performed when the door 11 is being closed. This can be necessary for example when a plurality of damped furniture hinges 20 are used on one door 11. The setting head 41 of the adjustment element 40 is advantageously disposed in the interior space of the hinge boss 30. Said setting head 41 is thus accessible in the case of an assembled furniture hinge 20.
(17) The damper 60 in the assembly region 34 is disposed outside the hinge boss 30. It is merely the cylinder 62 of the damper 60 in the centering region 31 that protrudes into the interior space of the hinge boss 30. The depth of the hinge boss 30 in the assembly region 34 is reduced so as to be less than in the centering region 31. On account thereof, an outside space for receiving the housing 50 having the damper 60 is formed between the base 34.1 of the assembly region 34 and the termination of the bore in the door 11, the hinge boss 30 being set in said bore. This outside space can be described as being outside of the assembly region 34 on an opposite side of the base 34.1 of the assembly region from the interior space of the hinge boss 30. The spring 24 in the assembly region 24 is also guided outside the hinge boss 30. The accessible interior space of the hinge boss 30 in the assembly region 34 is thus clear of additional components. The base 34.1 of the assembly region 34 forms a major part of the accessible surface of the hinge boss 30. Said base 34.1 is preferably made from metal. This leads to a surface of the hinge boss 30 that is able to bear loads and is easy to clean. The damper 60 per se is disposed so as to be protected from external influences by the base 34.1.
(18)
(19) The centering region 31 has a boss base 31.1 which by way of boss side walls 31.2 and of a rounded portion 31.4 is disposed so as to be spaced apart from the bearing face 32. In each case one articulation receptacle 31.3 is provided as cut-out in the boss side wall 31.2 shown and the opposite boss side wall 31.2. The base 34.1 of the hinge boss 30 in the assembly region 34 is spaced apart from the bearing face 32 by way of side walls 34.2. The spacing herein between the bearing face 32 and the base 34.1 of the assembly region 34 is smaller than the spacing between the bearing face 32 and the boss base 31.1 of the centering region 31.
(20) Three latching clearances 35.1, 35.2, 35.3, preferably as rectangular cut-outs, are incorporated in the base 34.1 of the assembly region 34. A further round cut-out forms an adjustment element guide 37. A first latching receptacle 37.1 and a second latching receptacle 37.2 are disposed on the periphery of the adjustment element guide 37. The latching receptacles 37.1, 37.2 are embodied as cut-outs of the base 34.1 that are connected to the adjustment element guide 37 and from the latter point outward radially. A chamfer-shaped molding 36 is incorporated in the base 34.1 between the adjustment element guide 37 and the first latching clearance 35.1 on the one side, and between the second and the third latching clearance 35.2, 35.3 on the other side. The molding 36 is closed toward the external periphery of the assembly region 34 and is embodied so as to be open toward the centering region 31.
(21) In a manner lateral to the assembly region 34, the lateral flanges 33 are molded opposite one another to the side walls 34.2 of the assembly region 34 and to the bearing face 32. The lateral flanges 33 have assembly bores 33.1 for receiving the screws 25 shown in
(22) The hinge boss 30 is preferably embodied as a deep-drawn part from metal.
(23) The housing 50 is disposed opposite the assembly region 34. Said housing 50 has a housing base 51 that is cut out by a cut-out 52. The housing base 51 is connected to side wall portions 57.1 of the housing 50. The first fastening element 55.1 that is visible in the chosen perspective is molded so as to be integral to the housing 50. The housing 50 toward the periphery of the hinge boss 30 has a curved wall portion 57.2. A spring receptacle 53 is incorporated in the curved wall portion 57.2. The spring receptacle 53 herein is molded so as to be integral to the housing 50, in the present exemplary embodiment as a groove therein. The housing 50 toward the centering region 31 of the hinge boss 30 is open by way of a housing opening 59.
(24) The damper 60 is disposed opposite the housing opening 59. The damper is preferably embodied as a hydraulic linear damper, having a piston 61 and the cylinder 62. Facing away from the hinge boss 30, the cylinder 62 has a flat cylinder face 67.
(25) The spring 24 is assigned to the housing 50, so as to be opposite the damper 60. The spring is formed from two leg springs 24.2 which are disposed so as to be mutually opposite and connected to a spring bracket 24.1. The free ends of the leg springs 24.2 are aligned in the direction of the centering region 31.
(26) Proceeding from the open side of the hinge boss 30, the adjustment element 40 faces the adjustment element guide 37. The adjustment element 40 along the central longitudinal axis thereof has the setting head 41, a guide portion 43, a subsequent adjustment portion 44, and a terminating first fastening element 45. The diameter of the adjustment element 40 is tapered in the transition from the setting head 41 to the guide portion 43. The face of the setting head 41 that is thus formed and faces the guide portion 43 forms a second fastening portion 41.1. A latching appendage 42 is molded on the second fastening portion 41.1. The fastening portion 41.1 and the latching appendage 42 are preferably disposed so as to be radial to the central longitudinal axis of the adjustment element 40.
(27) For assembly, the damper 60 is inserted through the housing opening 59 into the housing 50. The spring 24 by way of the spring bracket 24.1 thereof is fixed in the spring receptacle 53 of the housing 50. The articulated lever 23 shown in
(28)
(29) The housing 50 having the spring 24 and the damper 60 is fixed to the assembly region 34 of the hinge boss 30 from the outside. The housing 50 herein is fastened to the hinge boss 30 by way of the fastening elements 55.1, 55.2, 55.3, and by way of the adjustment element 40. The boss depth of the hinge boss 30 in the assembly region 34 is reduced in relation to the boss depth in the centering region 31 to the extent that the housing base 51 of the housing 50 lies in the plane of the boss base 31.1 of the centering region 31. The centering region 31, the assembly region 34, and the housing 50 form an external contour of the furniture hinge 20, said external contour being adapted to the shape of standardized bores for receiving hinge elements in items of furniture 10. The furniture hinge 34 can thus be centered and assembled in bores that are known for items of furniture 10. When assembled on the item of furniture 10, the housing base 51 of the housing 50 lies directly opposite the termination of the bore in the item of furniture 10, such that the housing 50 cannot be released from the assembly region 34 even in the case of forces that act from the outside, for example by way of the spring 24 or of the damper 60.
(30) The spring 24 by way of the spring bracket 24.1 thereof is held in the spring receptacle 53 of the housing 50. The leg springs 24.2 are guided so as to be lateral to the housing 50. A major part of the spring 24 is thus disposed outside the hinge boss 30. Merely the free ends of the spring 24 are guided into the centering region 31 and to the guide curves 23.2 therein. On account thereof, the interior space of the hinge boss 30 in the assembly region 34 is clear of additional components and can thus be cleaned in a correspondingly easy manner. The housing 50 assumes a dual function. Said housing 50 serves for receiving the damper 60, on the one hand. The spring 24 is fastened to the housing 50, on the other hand. The housing 50 having the damper 60 introduced and the spring 24 attached can thus be fastened as a pre-assembled functional unit to the assembly region 34 of the hinge boss 30. No additional holding devices, by way of which the spring 24 has to be connected in a separate assembly step, are thus required for the spring 24 on the hinge boss 30. On account thereof, the assembly time for the furniture hinge 20 can be minimized. Furthermore, the components which transmit a force to the articulated lever 23, specifically the spring 24 and the damper 60, as a pre-fabricated functional unit, can be tuned to one another in an optimal manner.
(31)
(32) The damper 60 in the insertion direction is disposed ahead of the housing opening 59 of the housing 50. To this end, the piston 61 points in the direction of the piston guide 54. The cylinder 62 is configured as a plastic molded part. A dished cylinder face 66 is disposed so as to be opposite the flat cylinder face 67. In each case three guide rails 63.1, 63.2, 63.3 are molded on both sides between the flat and the dished cylinder face 67, 66, respectively. A detent 65 is attached to that side of the cylinder 62 that faces the cut-out 52 in the housing base 51, so as to be between the first and the second guide rail 63.1 63.2. A ramp 64 is disposed on that end of the cylinder 62 that is opposite the piston 61, toward the dished cylinder face 66.
(33) For assembly, the damper 60 is pushed into the housing 50. The first and the second guide rails 63.1, 63.2 herein engage in the guide grooves 56 of the housing 50. The third guide rails 63.3 are in each case guided in the space between the guide webs 56.1 and the housing base 51. The flat cylinder face 67 lies opposite the housing base 51. The piston 61 at the end side is plug-fitted into the piston guide 54. The piston 61 is thus mounted so as to be movable in a linear manner in the housing 50. The piston 61 is fixed to the housing 50. The cylinder 62 is adjusted in relation to the piston 61 by displacing the cylinder 62 in the direction toward the interior space of the housing 50. This causes the damping action.
(34)
(35) The free ends of the spring 24 are guided through the opening 38 in that boss side wall 31.2 of the centering region 31 that faces the assembly region 34 into the latter. The opening 38 is conceived such that the free ends of the spring 24, in addition to the cylinder 62 and so as to be lateral to the housing 50, can be guided into the centering region 31.
(36)
(37) The cylinder 62 in this second adjustment position does not protrude into the adjustment travel of the articulated lever 23 shown in
(38)
(39) The adjustment element 40 is rotated to the second adjustment position thereof. The adjustment portion 44 forms a ring that is not closed. The ring at the end side has a detent face. The adjustment portion 44 in the second adjustment position is guided between the first and the second guide rail 63.1, 63.2 in such a manner that the detent face of the adjustment portion 44 bears on the detent 65 of the cylinder 62. On account thereof, the cylinder 62 is blocked in terms of the linear movement thereof. The adjustment portion 44 and the detent 65 are disposed such that the cylinder 62 is blocked in the retracted position thereof. The cylinder 62 thus no longer protrudes into the adjustment travel of the articulated lever 23, and the movement of the furniture hinge 20 is no longer damped.
(40)
(41) The furniture hinge 20 in the exemplary embodiment shown is formed from the hinge boss 30, the detent element 21, and the articulated lever 23. However, any other fastening possibility, for example a second non-damped hinge boss 30, can be provided instead of the detent element 21.
