  • the weight-compensating spring serves as far as possible to absorb the forces occurring when a door is opened about a horizontal, lower axis and to prevent an uncontrolled opening of the door. Conversely, the folding-up of the door from an open position is significantly facilitated by the weight-compensating spring.
  • the closing spring fulfills the purpose of urging the door shortly before reaching the final closed position with a force acting in the closing direction spring force and thus initiate a self-closing.
  • the closing spring causes the door is held in the closed position by the force of the closing spring in the closed position.
  • the US Pat. No. 6,397,836 B1 discloses a mounting kit for a oven hinge.
  • the oven door can be pivoted after mounting the items to the hinge on the oven door about a lower horizontal axis.
  • the hinge has a mounting part for attachment to the furnace housing.
  • the door hinge also has a weight compensation spring, with an adjoining damping device.
  • the EP 1 555 372 A1 discloses a door hinge, for a furniture which is pivotable about several horizontal axes.

  • the damping part interacts with a connection which is arranged between two of the above-mentioned several axes and whose mobility is reduced or damped by the damping part.
  • the DE 10 2005 002 822 A1 discloses an oven door hinge.
  • This door hinge has a first and a second hinge part, a sliding part coupled to the second hinge part and a spring, wherein the first hinge part, the spring and the displacement part form a structural unit.
  • the EP 1 847 670 A2 discloses a hinge for a household electrical appliance with a damping element, which allows damping of the closing movement. Furthermore, two spring elements are arranged in a housing. The hinge is divided into two hinge parts, which are fixed to the door of the oven and to the oven cabinet.
  • the present invention has for its object to provide a door hinge of the generic type, which causes an improvement in the movement sequences when opening or closing a door, especially in the Endlagen Symposiumen.
  • the damping device consists of a double-acting damping cylinder
  • the damping cylinder is loaded upon reaching the closed position or upon reaching the opening position in each case from its opposite end sides with the result that the damping forces are the same in both the closing direction and in the opening direction.
  • the damping device consists of two damping cylinders, wherein a damping cylinder for the damping of the closing forces and the other damping cylinder for the damping of the opening forces is provided.
  • FIG. 1 is denoted by the reference numeral 1 a total oven, in which a door 2 is connected by means of two door hinges 3 about a lower, horizontal axis pivotally mounted on the body 4.
  • FIG. 1 serves only to clarify the position of the door hinges 3 in the assembled state.
  • a door hinge 3 comprises a door lever 5 which can be fixed to the door 2 and a housing 6 which can be secured to the carcass 4 of a baking oven 1 or a comparable domestic appliance, wherein the door lever 5 is connected to the housing 6 so as to be articulated about a main axis 7.
  • the main axis 7 corresponds to the axis about which the door 2 is pivotable relative to the body 4.
  • the hinge 3 has a weight-compensating spring 8, which serves to keep the door 2 when opening approximately in an equilibrium position.
  • the characteristics described so far are well known as well as a sake of clarity in the drawings, not shown closing spring, whose task is to pivot the door 2 shortly before reaching the final closed position without external forces in their closed position, so to cause a self-closing.
  • the weight-compensating spring 8 will pass through a linkage 9 and is supported at one of its ends on a stop 10 of the linkage 9 and at its other end on a support tab 11 of the housing 6.
  • the already mentioned closing spring is activated in a known manner, by which the door 2 is moved in the last angular range before the final closed position solely by the force of said closing spring in its closed position.

  • the linkage 9 is provided at its rear end facing away from the door with a projecting into the housing 6, bent driving lug 18 which lies between the opposing piston rods 14a of the damping cylinder 14.
  • the linkage 9 moves up to an end position according to FIG FIG. 11 to the left.
  • the driving lug 18 of the linkage 9 strikes the piston rod 14a of the rear damping cylinder 14 lying opposite the door and pushes this piston rod 14a into the damping cylinder 14. In this case, according to the characteristic of the damping cylinder 14, the closing movement is damped.
  • Another advantage of this invention is that in case of failure of a damping cylinder 14, the effect of the remaining other damping cylinder 14 is not affected, so that possibly only the damping effect when closing or when opening the door 2 fails.
  • FIGS. 14 to 20 a door hinge 3 is shown with only one damping cylinder 14.
  • This damping cylinder 14 is mounted in an upwardly open upper housing 19.
  • This upper housing 19 is the front side open to the door side and in its side facing away from the door 2 closed by a rear wall 19a.

  • toothed portions 23 a are arranged on the upper side of the guide webs 23, as on the opposite underside of the upper housing 19, toothed portions 23 a are arranged.
  • the lower housing 22 has a distance from the upper housing 19 and is provided on its underside with a guide groove 25, in which the linkage 9 engages in the region of a recess 9a.
  • the lower housing 22 is equipped with an end wall 26 which extends into the displacement area of the piston rod 14a of the damping cylinder 14.

  • the two abutment edges 9b each have the same distance to the end wall 26 of the lower housing 22 or to the rear wall 19a of the upper housing 19.
  • the linkage 9 is correspondingly moved to the right.
  • the door-facing behind stop edge 9b first passes in abutment with the rear wall 19a of the upper housing 19 and by further displacement of the linkage 9 in the same direction we then again with simultaneous execution of Relatiwerschiebung between the upper housing 19 and lower housing 22 which is supported on the end wall 26 piston rod 14a inserted into the housing of the damping cylinder 14 and the Opening movement accordingly damped.

  • the clearance of the opening 32 is selected so that the rotary levers 30 can pass through this opening.
  • the length of the opening 32 is greater than the distance of the rotary lever 30 to each other, so that a displacement of the rod 9 from the middle open position in the closing or opening direction initially has no effect on the damping device 13. If a pivoting position is reached in which the door 2 is about 15 ° before its closing or before its final open position, the front or the rear stop edge 9b of the aperture 32 hits one of the rotary lever 30. A further displacement in the same direction then causes a Pivoting the applied rotary lever 30 and leads - in the case of the closing process - to insertion of the piston rod 14a in the damping cylinder 14 or - in the case of opening - a displacement of the damping cylinder 14 in the direction of the piston rod 14a. As a result, either the closing process or the opening process is damped.
