Definitions

  • the invention relates to a hinge for a stove flap, which can also be referred to as a "stove hinge", according to the preamble of claim 1.
  • Such stove hinges are already known. They generally have a housing on which a plug-in part is pivotally mounted. The housing is attached to the stove flap. The plug-in part is inserted into the cooker or into the cooker housing, for example a side wall, or fastened there in some other way. However, it is also possible to attach the housing to the stove and the plug-in part to the stove flap.
  • the housing can be essentially box-shaped. The pivot axis can be located in a corner of the housing, for example in a lower outer corner, in particular on that side of the housing that faces away from the part of the plug-in part protruding from the housing.
  • Stove hinges of this type often have a spring through which the weight of the stove flap is to be balanced.
  • the stove flap is usually pivotally mounted on a horizontal axis on the front of the stove, the stove flap being in the closed position vertically above the swivel axis and being able to be swung outwards to an angle of, for example, 90 °.
  • the opening torque of the hearth flap increases in a substantially sinusoidal course.
  • This opening torque (door torque) of the stove flap can be compensated by the spring of the stove hinge.
  • a certain closing force of the stove flap can be generated in its closed position by the spring.
  • the object of the invention is to propose a stove hinge by which the torque generated by the spring can be influenced in a simple manner.
  • the hinge comprises a spring guide which is loaded by a spring.
  • This spring is preferably a torsion spring or spiral spring.
  • the spring guide is provided with a roller which is guided in a curve (guide curve, guide path) of the plug-in part.
  • a roller in the actual sense, another guide element can also be used, which is rigidly designed and slides in the curve or guideway or which is designed to be pivotable and which can perform a pivoting movement when sliding along the curve or guideway.
  • the roller or the other guide element can be guided in the curve or guide track. However, it can also be guided in a different way through the curve or guideway.
  • the torque exerted by the hinge on the stove flap can be influenced by the configuration of the curve. This torque depends on the course and the inclination of the guideway and the angle of rotation or opening angle achieved.
  • the spring preload is controlled via the course of the guideway. Special positions, detents and / or additional torques can be achieved via the inclination of the guideway.
  • the spring is preferably designed as a compression spring.
  • a compression spring in particular a torsion spring, which is loaded under pressure, is less susceptible to vibration than a spring loaded under tension, so that less disturbing noises are generated become.
  • a tension spring can also be used to carry out the invention.
  • a further advantageous development is characterized in that the roller is provided on an outwardly pointing tab of the spring guide.
  • the roller is preferably located outside the housing of the hinge.
  • the curve in the closed position of the hinge has an inclination which brings about the required closing force.
  • stove flaps must reach a certain closing force. This closing force can be generated in a simple manner by the corresponding inclination of the curve.
  • a further advantageous development is characterized in that the curve has a neutral section at a certain opening of the hinge. This is preferably an opening angle of approximately 20 °, which forms the so-called "grill stop". However, the angle can be in the range from 10 ° to 30 ° and, in certain cases, can also be more or less.
  • the neutral section of the curve causes the stove flap to "stop" at the specified opening angle.
  • the curve is preferably designed such that the spring force generated on the basis of the curve essentially compensates for the opening torque or door torque of the stove flap.
  • the advantageous development mentioned can be designed in such a way that the spring force generated due to the course of the curve essentially compensates for the opening torque of the stove flap in those areas which are outside the closed position and / or the specific opening position.
  • the spring guide is preferably guided in the housing. This guidance is preferably achieved by a support, which is preferably a support made of plastic or another suitable material.
  • the lever arm of the roller can be changed relative to the pivot axis of the plug-in part.
  • the spring guide has a guide pin which is guided in a further curve of the housing.
  • the spring preload can be changeable. It is advantageous if a stop for the spring is adjustable. This stop can be designed as a nut or comprise a nut, so that a change in the spring preload can be generated by rotation. The arrangement is preferably such that the nut or the other component for changing the spring Preload is adjustable by hand.
  • the hinge can be adapted to different stove flaps by changing the spring preload.
  • a locking part is connected to the plug-in part.
  • the locking part is preferably pivotable. It is advantageous if the pivot axis of the locking part is displaceable.
  • the locking part can have a wedge.
  • the locking part preferably has an actuation projection.
  • the locking part has an end face which forms a stop face. In this way it can be achieved that a reliable locking effect can also be achieved if the dimensions of the locking part and / or the parts interacting with it deviate from the specified values due to manufacturing tolerances and / or signs of wear.
  • the distance of the end face from the pivot axis of the locking part increases with increasing pivoting of the locking part. In this way, it can be achieved that the locking effect is sufficient even if the distance between the pivot axis and the part interacting with the end face of the locking part, for example a corner of the counter bearing, should be greater than specified due to manufacturing tolerances and / or due to Signs of wear should increase with time.
  • the end face is preferably curved.
  • the end face has an arc-shaped or at least substantially circular-arc-shaped contour, the center of the arc being spaced from the pivot axis of the locking part. It can thereby be achieved that the distance of the end face from the pivot axis of the locking part increases with increasing pivoting of the locking part.
  • the invention further relates to a stove flap and / or a stove.
  • a stove flap With previously known stove flaps it is often necessary to use two hinges. If the stove flap needs a weight balance, each of the hinges must have a weight balance in known solutions, each comprising a relatively large spring.
  • Another object of the invention is to propose a simplified stove hatch.
  • this object is achieved by a hinge according to the invention and a blind hinge with a housing on which a plug-in part is pivotably mounted.
  • the hinge according to the invention makes it possible to fully implement the weight compensation.
  • the arrangement can be made such that the entire weight compensation for the stove flap is achieved by a hinge according to the invention. Weight compensation is then no longer necessary for the second hinge of the stove flap.
  • no hinge according to the invention is required for the second hinge of the stove flap, but only a simplified hinge, that is to say a "blind hinge", which comprises a housing on which a plug-in part is pivotably mounted.
  • the second hinge or blind hinge does not require a spring guide which is loaded by a spring and which is provided with a roller which is guided through a curve of the plug-in part. This can simplify and reduce costs.
  • the blind hinge comprises a spring, in particular a leg spring, which is mounted on the housing and on the plug-in part.
  • a closing torque can be generated by this spring.
  • the blind hinge has a lock.
  • the spring or leg spring can generate a small closing torque in order to maintain the function of the lock.
  • the blind hinge has one or more features of the lock. Accordingly, a locking part, which is preferably pivotable, is preferably connected to the plug-in part of the blind hinge, the pivot axis of the locking part preferably being displaceable.
  • the blocking part of the The blind hinge can have a wedge. It can also have an actuation projection.
  • the locking part of the blind hinge has an end face forming a stop surface, the distance of the end face from the pivot axis of the locking part preferably increasing with increasing pivoting of the locking part.
  • the end face is preferably curved.
  • the end face can have a circular arc-shaped or substantially circular arc-shaped contour, the center of the circular arc being spaced from the pivot axis of the locking part.

  • the outer end face of the locking part 25 lies against the edge 39, which delimits the slot 24 at the top. A further closing of the hinge, ie a further pivoting of the hinge clockwise around the axis 10, is prevented. If the stove flap is raised in this locked position, the plug-in part 2 is unhooked. The extension 34 of the plug part 2 slides down out of the tabs 33 and the stove flap can be removed.
  • the stove flap is opened a little further by pivoting the housing 1 counterclockwise from the locked position shown in FIG. 9 about the axis 10. In this position, the locking part 25 can be pivoted clockwise about the pivot axis 26. The lock is thus released and the stove flap can be closed, so the housing 1 can be pivoted further clockwise about the axis 10.
  • the closed region 40 of the housing 1 lying above the upper edge 39 of the slot 24 engages.
  • the actuation projection 31 is closed on this Area 40 above the edge 39 and is reliably brought into the locked position shown in FIG. 7 and held there.
  • FIGS. 10 to 13 show a modification of the hinge shown in FIGS. 7 to 9, in which corresponding parts are provided with the same reference numerals.
  • the locking part 25 ' has an end face 41 which forms a stop face.
  • the pivot axis 26 'of the locking part 25' is not movable, but fixed.
  • the circular arc 42 formed by the radius r around the center m, on which the end face 41 lies extends in the region above the intersection 43 of this circular arc 42 with the circular arc 44 formed by the radius R around the center M above this circular arc 44.
  • the radius R corresponds to the distance of the corner 38 forming a stop edge from the center point M of the pivot axis 26 'of the locking part 25'.
  • the locking part 25 falls due to its own weight by executing a rotation about the pivot axis 26' until its curved end face 41 strikes the upper outer horizontal edge of the counter bearing window 45, that is to say at the corner 38, and thereby the connection of the plug-in part 2 locked with the counter bearing 32.
  • the permissible tolerance X is determined in the horizontal direction and Y in the vertical direction. It is important to ensure that a value dependent on the friction of the material pairing is not exceeded in order to preserve the principle of self-locking.
  • FIG. 12 shows the locked position in which the end face 41 rests on the edge 39.
  • An intermediate position is shown in FIG. 12
  • FIGS. 14 to 16 show a blind hinge 46 which can be used together with a hinge according to the invention, for example according to one of the embodiments shown in FIGS. 1 to 13, for a stove flap.
  • the hinge according to the invention is dimensioned such that it can absorb the forces required to balance the weight. This is made possible by the invention.
  • the second hinge of the hearth flap can then be formed by the blind hinge shown in FIGS. 14 to 16, in which there is no weight compensation.
  • the blind hinge according to FIGS. 14 to 16 lacks a spring guide which is loaded by a spring and which is provided with a roller which is guided through a curve of the plug-in part.
  • the blind hinge 46 comprises a housing 1, in which a plug-in part 2 is pivotally mounted about an axis 10, and a leg spring 47, which generates a small closing torque in order to maintain the function of the lock, which is ensured by a locking part 25 'and the other components of FIG 10 to 13 embodiment shown is formed.
  • the leg spring 47 is mounted on the housing 1 and the plug-in part 2. It is supported at one end in the housing 2, encloses the bolt of the axis 10 in several turns and then extends with its other end to a stop bolt 48 provided on the plug-in part 2, which it engages with its other end.
  • the blind hinge 46 can be used in combination with a spring hinge according to the invention, for example according to one of the embodiments in FIGS. 1 to 13, to save costs. It has the function of an axis of rotation and, when opened, does not generate any torque to compensate for the door weight.
  • the blind hinge 46 does not require a compression spring or a mechanism for transmitting the forces. It can therefore be manufactured more cheaply.
  • a hinge can be created on the principle of double-acting, simple or superimposed control cams.
  • the curve 9 causes a stronger or weaker biasing of the spring 6 and thus a control of the hinge torque over the course of the opening angle.
  • Curve 9 can also be designed to be double-acting in such a way that the slope of the customer profile can generate increasing resistance or an additional torque and in this way in particular it is possible to increase the additional torque during the closing process or to create detent positions ,
  • the further curve 4 offers a further possibility of influencing the torque curve over the opening area of the hearth flap by changing the lever arm h of the acting force in relation to the pivot point 10.
  • the bandwidth of the torque influence can be expanded by superimposing the two curve controls 9 and 4, so that the size of the hinge can be significantly reduced.
  • the interaction of the two curves 9 and 4 makes it possible to achieve almost any desired hinge characteristics.
