Definitions

  • the invention relates to a combustion chamber, in particular for a closed stove, with at least one closure element for closing the combustion field, wherein the closure element is connected to a rack and an engaging in the rack gear and a gear connected to the rotary handle in an open and closed position can be brought.
  • combustion chambers are known in closed stoves, which have a transparent, the view of a burning in the combustion chamber fire-releasing window. These stoves are operated with spirit.
  • the object of the invention is therefore to propose a combustion chamber of the type mentioned above, which automatically closes the combustion field of the combustion chamber during vibration, so that the fire extinguishes.
  • closure element against the force of a preloaded spring on the rotary handle can be brought into the open position and that a fixing lever is provided with two lever arms, one lever arm in the open position cooperates with the rack and the other lever arm has a bearing plate on which there is a weight, so that the one lever arm with its free end holds the rack against the force of the spring in the open position.
  • a locking recess for the free end of a lever arm is provided in the rack, wherein the diameter of the Arreti LucassEnglishung is smaller than a diameter of the free end of a lever arm and wherein the free end of a lever arm is curved.
  • a plurality of Arretierausappelgeber are spaced apart in the rack.
  • the weight is formed as a ball.
  • the ball is flattened.
  • the bearing plate has a recess for receiving the weight.
  • the bearing plate is advantageously oriented horizontally.
  • the rotary handle is releasably connected to the gear.
  • the rotary handle is non-positively connected against the force of a prestressed spring with the gear.
  • the closure element is designed as a slide, in particular as a relative to a frame delimiting the combustion field, particularly preferably slidable slider parallel to the surface of the combustion field.
  • two closure elements are provided, which are each connected to one end of the spring.
  • a combustion chamber 1 consists of a bottom 3, four side walls 4 and a ceiling.
  • the ceiling is formed as a frame 2, which surrounds a combustion field 5.
  • the four side walls 4 may differ from each other.
  • closure elements 10, 20 are slidably received on the frame 2, two closure elements 10, 20 are slidably received.
  • the closure elements 10, 20 facing each other have a contour 11, which is adapted to the respective other contour of the other closure element.
  • the combustion field 5 is closed.
  • the closure elements 10, 20 are braced against each other with a spring 15, so that the combustion field 5 is closed without any other constraint on the closure elements 10, 20.
  • the closure elements 10, 20 are each connected to a rack 12, 22.
  • the rack 12 of the first connecting element 10 is located according to the Figures 3 and 4 above the second rack 22 of the second closure element 20.
  • a gear 42 is arranged between the racks 12 and 22, between the racks 12 and 22, a gear 42 is arranged.
  • the gear 42 engages with a toothing in the first rack 12 and in the second rack 22 a.
  • the gear 42 is seated on a drive shaft 44 which is driven by means of a turning handle 46 designed as a turnstile.
  • the rotary handle 46 is displaceable parallel to the axis of the drive shaft 44 counter to the force of a further spring 47.
  • the rotary handle 46 engages in a force-locking manner in the drive shaft 44 or an element connected to it in a rotationally fixed manner when it is pressed in the direction of the combustion chamber 1.
  • the other lever arm 35 of the locking lever 32 has a bearing plate 34 for a weight 30.
  • the bearing plate 34 is executed according to the embodiment with a square recess 36 ( Fig. 5 ), the weight 30, in the illustrated embodiment, a metal ball, centered in the bearing plate 34.
  • the weight 30 thus complains the other lever arm 35 and presses the free end of the one lever arm 31 upwards of the second rack 22 against.
  • the automatic closing of the combustion field 5 of the combustion chamber 1, which causes a fire to extinguish, is triggered by the weight 30 falling from the bearing plate 34, such as Fig. 3 shows.
  • the fixing lever 32 is no longer one-sided weighted by the weight 30.
  • the weight 30 originally supporting lever arm 35 of the fixing lever 32 provides after falling of the weight 30 at most with its own weight for the fact that the lever arm 31 engages the rack 22.
  • the spring 15 contracts the closing elements 10, 20, the curved end of the lever arm 31 is forced out of the locking recess 23. The engagement of the fixing lever 32 in the rack 22 is thus solved.
  • the adhesion between the lever arm 31 and the rack 22 can be configured arbitrarily. Instead of the illustrated engagement of a curved surface in a locking recess 23, the lever arm 31 may alternatively be in frictional engagement with the rack with its free end.
  • the illustrated embodiment of the metal ball 36, which in the square recess 36 (FIG. Fig. 5 ) of the bearing plate 34 can also be replaced by alternative solutions.
  • any body having at least one flat on a flat surface of the bearing plate 34 may be aligned.
  • the sensitivity of such a trigger in the case of, for example, shocks can be adjusted by, for example, the bearing plate 34 is inclined out of the horizontal addition.
  • the ratio of the diameter of the weight 30 received in the recess 36 to the recess should be selected according to the desired sensitivity. If an alternative trained weight only with a flattening on a bearing surface, the size of the flattening determines the sensitivity of the triggering.
