Definitions

  • the invention relates to a 180 ° concealed hinge for series cabinets, consisting of a first bracket attached to the cabinet housing, with a first pivot bearing axis lying parallel to and near the door leaf front surface, and a second bracket attached to the door leaf with a parallel to the first pivot bearing axis, in the rest position in substantially parallel to the door leaf plane offset second pivot bearing axis, and with a hinge connector which is pivotally mounted with respect to the first and the second pivot bearing axis, and with a spring device on one of the pivot bearings, which urges the hinge connector into a rest position with respect to the associated bracket.
  • this hinge is the fact that although this hinge is not visible from the outside, it does require a considerable amount of space within the cabinet space. Another disadvantage is that the pivot points are relatively far apart due to the design and therefore considerable leverage acts on the individual parts of the hinge, so that their dimensioning must be kept correspondingly strong, which increases the cost of the material.
  • the object of the invention is to improve the concealed hinge according to the type mentioned in such a way that it does not take up any usable space within a row cabinet, but on the other hand also projects as little as possible over the front surface of the row cabinet doors and, if possible, also remains largely invisible.
  • the door should be practically the same size as the cabinet body.
  • the hinge connector is in the form of a fork encompassing one bracket and the other bracket is in the form of a fork encompassing the hinge connector, and in that the axis of one pivot bearing the prongs of the hinge connector and one bracket and the axle of the other The pivot bearing penetrates the fork leg of the hinge connector and the fork prongs of the other fork-shaped bracket.
  • the fork-shaped bracket is the bracket attached to the door leaf.
  • the axes are formed by pins, which are each press-fitted with at least one end in a fork prong, the ends of the pins being flush with the respective outer surface of the fork or springing back slightly. This arrangement enables a particularly inexpensive and space-saving embodiment.
  • the spring devices can comprise a spiral spring, in particular a torsion spring, arranged within the fork web around the associated pin, so that the space requirement for the spring device remains extremely small.
  • Trestle, bracket-shaped trestle and hinge connector are preferably designed such that when the trestle is pivoted with respect to the hinge connector from the (forming a closed door) rest position, the trestle strikes the hinge connector by approximately 90 °.
  • stop is formed by an angular surface, e.g. in the form that in the rest position (closed door) the hinge connector strikes the forked trestle in such a way that the stop surface forms at least two mutually perpendicular stop surfaces.
  • an embodiment has proven to be particularly favorable in which the trestles are attached to the cabinet housing or to the door leaf by means of cap screws passed through the sheet metal.
  • the concealed hinge is fastened in that the bracket attached to the door leaf is fixed on the one hand by means of a plug connection and on the other hand by means of clamping studs.
  • FIG. 1 shows an outer view of a first embodiment of the 180 ° concealed hinge 10 according to the invention, which can be used in row cabinets 12, consisting of a first bracket 16 fastened to the cabinet housing 14 with the first pivot bearing axis 20 lying parallel to and near the door leaf front surface 18 , and a second bracket 24 fastened to the door leaf 22 with a pivot bearing axis 26 which is offset from the first pivot bearing axis in the rest position of the hinge substantially parallel to the door leaf plane 2, reference number 28 is arranged.
  • a hinge connector 30 can be seen, which is pivotally mounted in the first (20) and in the second pivot bearing (26), and which is linked to a spring device 32 on the second pivot bearing 26 such that the hinge connector 30 with respect to the second bracket 24 in one the closed position of the door representing rest position (Fig. 2) is pushed.
  • the hinge connector 30, see in FIG. 10 the side view A has the shape of a fork encompassing the bracket 16 shown in FIG. 11, consisting of the fork tines 34 and the The fork web 36 connecting the two tines 34, the axis of the one pivot bearing, reference number 20, penetrating the fork prongs 34, while the other, second axis of rotation, reference number 26, pierces the fork web 36, see in particular the side view (lower partial figure) of FIG. 10.
  • a recess 38 for receiving a spiral spring 34, which is supported with its one end 40 on the inner wall 42, which is formed by the recess 38 in the fork web 36, and on the other hand with its end 44 supports a surface 46 which is formed by the second bracket 24, see Fig. 9.
  • the spring 40 is shown in Fig. 17 in its rest position, so that it is under tension in the position shown in Fig. 2, by which Spring generates a torque that tries to pivot the hinge connector 30 with respect to the second bracket 24 in the counterclockwise direction about the pivot point 26 (seen in FIG. 2).
  • the hinge connector 30 has a nose-like projection 48 at the end of its fork tines, with which the hinge connector swivels under the pressure of the spring 32 about the axis 26 against a contact surface 50 which lies away from the second Bock 24 is formed according to FIG. 9.
  • this contact surface 50 is even angular, that is, it consists of two mutually perpendicular surfaces 50, 52, the surface 54 of the hinge connection piece bearing against the contact surface 52.
  • Non-positive engagement in the axial direction is achieved by the fork side surfaces 54 of the hinge connector 30 resting on corresponding fork inner surfaces 58 of the second bracket 24, see FIGS. 9 and 10 in conjunction with FIG. 3.
  • the spring 32 holds the two parts 30 and 24 in frictional contact with one another, so that the two parts practically act mechanically as a one-piece part, especially since the projection 60 forming the surface 46 of the second bracket 24 also forms a further surface 62, against which a third surface 64 of the hinge connector 30 can rest.
  • the door leaf 12 which has a bevel 66 at its end, is cut in at the height of the hinge, with both the bevel 66 and part of the actual door leaf 12 being cut out to a depth B over a distance A.
  • the edge 72 of the door cutout, see FIG. 3 lies in a corresponding one of the second bracket 24 formed contact surface 74 and overlaps with the corresponding edge area 78 of the door panel in area 76.
  • This edge area extends to the bevel 66, and the second bracket 24 surrounds this bevel with a fastening area 78, each of which has a countersunk bore 80.
  • the second bracket rests on the outer surface 84 of the bent part of the door leaf 12, whereupon with the aid of countersunk screws 86 after inserting the bracket, in particular inserting the edge 68 into the slot 70 and applying the surface 82 to the surface 84 the trestle can be securely fastened to the door leaf 12, for example in that the screws 86 are screwed into corresponding threaded bores in the bent part 66 of the door leaf.
  • the construction represents a particularly secure and visually appealing attachment to the door leaf, the trestle covering the cut-out edges by the projecting areas 76 and 78, respectively.
  • the second trestle again has the shape of a fork, with fork tines 88 and a fork web 90, the fork web being formed by a first web region 92, which also forms the groove 70, and a second web region that forms the projection 60.
  • the two web areas or webs 92, 60 define between them a free space 94 in which the hinge connection piece 30 can be inserted in a precisely fitting manner, the bore for the second
  • the axis of rotation 26 of the hinge connection part 30 lies coaxially with bores 94 which are arranged in fork walls 96, which fork walls 96 are kept at such a distance from the web areas 92 and 60 with their inner surfaces that the width of the hinge connection piece 30 with very little play around an axial pin 98 can be rotatably supported, which can be seen in Fig. 3 and was drawn out as an individual part in Fig. 15.
  • the axial pin 98 is pressed with its one corrugated end into one of the two bores 94, so that the pin 98 cannot fall out of its own accord after the hinge connector 30 has been inserted into the second bracket 24.
  • the pin has a length such that it does not protrude beyond the outer surface 102 of the fork wall 96, which facilitates the subsequent assembly of the hinge in the corresponding cutout of the door leaf 18.
  • the spring 32 is also brought into position such that the pin penetrates the spiral of the spring 32, as can be clearly seen in FIG. 3.
  • the construction of the two parts 24 and 30 is such that the part 30 can move with respect to the part 24 against the force of the spring from the stop position of the surfaces 52, 54 around the axis 26 by about 90 ° from each other until the Surface 104 of the hinge connector 30 abuts the surface 106 of the second bracket and takes this bracket along with further rotation. So that the arm 44 of the spring 32 does not hinder this movement, the hinge connection piece 30 also has an incision 108 into which this spring arm penetrates in the 90 ° position, see also FIG. 4, for example.
  • the first bracket 16 is shown in greater detail, which has a width C which corresponds approximately to the inner fork spacing between the fork tines 48 of the hinge connector 30, so that the first bracket 16 can be inserted between the fork tines 48 with only a small amount of axial play and then a corresponding axial pin 110 can be inserted to form the first pivot bearing axis 20, this pin 110 in turn can be provided with a corrugated end 100 in order to also hold this pin in the position corresponding hole 112 of the fork tines 48 of the hinge connector 30 to be able to press fit.
  • the pin 110 penetrates a bore 114 of the first bracket 16 with little play, so that it can be pivoted around the pin between the two fork tines 48 from a first position, which can be seen in FIG. 2, into a position rotated by approximately 90 ° 4, in which the surface 116 of the head of the bracket 16, which protrudes from the circular shape, bears against the contact surface 118 of the hinge connection piece 30.
  • the bracket 16 can be screwed onto the cabinet housing 14 by means of a screw 120, for example through a threaded blind hole 122, as shown in FIG. 11.
  • the screw 120 is the only part that projects into the clear space of the actual cabinet housing, while the remaining parts of the hinge lie within the already existing and for reasons of stability, dead space 124 between the cabinet housing 14 and the door leaf 22.
  • the hinge projects over the door leaf front surface 18 only by the material thickness of the wall 76 of the second trestle, that is to say about 1 to 2 mm.
  • the hinge arrangement could be made between two adjacent row cabinets in such a way that there is practically no gap 126 between hinge 10 of the row cabinet 12 and door 22 of the adjacent row cabinet 13 (or, if this has a door that opens in another direction, a corresponding hinge 10 of the row cabinet 13) occurs.
  • the hinge connection piece 230 is essentially of the same shape as the hinge connection piece 30, but with an additional wall 134 which hides the first bracket 216 arranged between the fork tines 48, see also FIG. 14, towards the front.
  • the trestle in contrast to the embodiment according to FIG. 14, has a depression 136 into which the wall 134 lies when the door is opened by 180 °, see FIG . 8th.
  • the second embodiment described here has another special feature.
  • the second bracket 200 is not attached by means of countersunk screws, as in the embodiment according to FIG. 9, but with the aid of a stud screw 136, FIG. 18, which can be screwed into corresponding threaded holes 138 in the fork prongs 88 in such a way that they between the chamfer 66 and the door leaf 22 corner area 140 presses against the corner 142 formed by the second bracket.
  • This type of fastening has the advantage that the relatively large fastening area 78 according to the embodiment of FIG. 3 can be reduced considerably, to less than half, because there is no longer any need for a countersunk bore for the fastening screw 86 is.
  • This means that the dimension F in the embodiment according to FIG. 5 remains considerably smaller than the corresponding dimension F in the embodiment according to FIG. 1. Since the first bearing block 16 also remains visible, the optical appearance of the embodiment according to FIG. 5 significantly improved.
  • the hinge according to the invention has a stable end position in two mutually perpendicular planes due to the construction shown: one plane is represented by the surface 64 (FIG. 10) of the hinge connection piece 30, which strikes the surface 62 of the bracket 24, and the second plane is formed through the surface 54 of the hinge connection piece 30 and the surface 52 of the bracket 24. This measure ensures that the resilient door seal 130 cannot bring the hinge out of the rest position into an undefined, unstable position.
