Definitions

  • the present invention relates to a revision flap with an outer frame which is connectable to a building part and a door or flap and a hinge with which the door or flap is rotatably or pivotally mounted on the outer frame.
  • inspection flaps are known from the prior art and are used in shafts, for example in ventilation or air conditioning shafts, in order to be able to inspect them. Since these inspection flaps usually have a fire protection requirement of 90 minutes and often are comparatively large, their installation is relatively difficult and expensive and usually done only with multiple installers.
  • a revision flap with an outer frame which is connectable to a building part and a door or flap and a hinge with which the door or flap is rotatably or pivotally mounted on the outer frame, wherein the hinge is detachably provided.
  • the present invention relates to a revision flap, as it is intended in particular for inspection purposes, for example in shafts, in particular ventilation shafts.
  • This inspection flap has an outer frame, with which it is connectable to a building part, such as the shaft.
  • the access door has a door or flap and a hinge, with which this door or flap is rotatably or pivotally connected to the outer frame. As a result, the access door can be unlocked for inspection purposes and placed around the hinge in an open position, so that the resulting opening can be used for auditing purposes.
  • this hinge is now provided detachably.
  • the door or flap can be reversibly separated from the outer frame in a simple manner, which is particularly advantageous in the assembly of the outer frame.
  • the outer frame can be connected separately from the door or flap with the building part. Only then is the door or flap arranged by means of the hinge on the outer frame.
  • the inspection flap according to the invention can be mounted in particular by a single fitter.
  • the inspection flap according to the invention has two hinges, which are preferably located opposite one another on the outer frame or on the door or flap. Around these two hinges, the door or flap is rotated or pivoted relative to the outer frame.
  • the inspection flap according to the invention has a closure which is provided between the door or flap and the outer frame and prevents the door or flap unintentionally opens.
  • the closure is preferably provided spaced from the hinge.
  • the hinge has a projection, in particular a bolt, which engages in a recess and / or indentation.
  • this recess and / or indentation is provided in the door or flap.
  • the door or flap has a frame and / or a filling in a preferred embodiment of the present invention.
  • the recess extends through the entire cross section of the frame and / or the recess preferably extends into the filling, for example in the form of a blind hole.
  • the filling is preferably an insulating board which satisfies decorative requirements and / or with which, for example, noise can be insulated.
  • the door or flap and thus the filling meets fire protection requirements of 90 minutes.
  • the indentation is plastically molded into the frame and more preferably also into the filling.
  • This preferred embodiment of the present invention has the advantage that the indentation at the same time represents a form / or frictional connection between the frame or the filling.
  • the indentation can also be generated by material removal.
  • the projection is movably provided so that it is reversibly removable from the recess and / or indentation. This removal can release the hinge and remove the door or flap from the outer frame.
  • the projection is tension-free in its locking position or it is biased in the direction of the recess and / or indentation, so that the hinge can not solve automatically.
  • the projection is provided on a flexible tab. Now, if this tab bent away from the door or flap, the projection moves away from the recess and / or indentation and the hinge is released.
  • this tab is positively and / or non-positively connected to the outer frame, for example by means of a rivet or by means of clinching, and / or materially bonded, for example by gluing.
  • the tab on an opening aid, with which it can be bent away, for example, from the outer frame in a simple manner.
  • the opening aid is particularly preferably a forming by which, for example, a gap is made available between the tab and the outer frame into which a tool, for example a screwdriver, can engage, with which the tab is then bent.
  • FIG. 1 shows the access door 6 according to the invention, which has a door or flap 1 and an outer frame 2.
  • the outer frame 2 is connected to a building part, such as a shaft, positive, non-positive and / or cohesive.
  • the door or flap 1 has in the present case a frame 1a and a filling 1b.
  • the door or flap 1 is rotatably attached to the outer frame 2 in the present case with two hinges 7, which are arranged on opposite sides of the inspection flap according to the invention. According to the invention, these hinges are now detachably provided, so that as soon as the hinges are released, the door or flap can be removed from the outer frame.
  • FIG. 2 shows an embodiment of a hinge 7, with which the door or flap 1 can be rotatably attached to the outer frame 2.
  • This hinge has a projection, here a pin 4, which engages in a recess 8, which is provided in the present case in the frame 1 a.
  • the door or flap 1 can rotate from a closed to an open position and vice versa.
  • the bolt 4 is arranged at one end of a tab 3, which in turn is connected at its other end by means of a fastening means 5 on the outer frame 2 of the inspection flap according to the invention.
  • the bolt 4 can also be provided on the door or flap and the recess 8 in the outer frame 2.
  • the tab 3 has an opening aid 3a, which in the present case is provided as a forming so that there is a gap or an enlarged gap between the outer frame and the tab into which a tool can be inserted in order to solve the problem Hinge the distance of the part of the tab on which the bolt 8 is located to increase, which in detail in FIG. 3 is shown.
  • an opening aid 3a which in the present case is provided as a forming so that there is a gap or an enlarged gap between the outer frame and the tab into which a tool can be inserted in order to solve the problem Hinge the distance of the part of the tab on which the bolt 8 is located to increase, which in detail in FIG. 3 is shown.
  • FIG. 3 shows the access door according to the invention in the dissolved state.
  • the outer frame can now be attached without the door or flap 1 to the building part. As a result, it has a much lower weight, which facilitates assembly and allows only a fitter.
  • the tab is bent away in the manner already described with a tool again from the outer frame 2 and the door or flap 1 can be used again in the outer frame. After the tool has been removed, the tab goes back to its original position and the projection here the bolt 4 jumps back into the recess / indentation 8 of the door or flap 1, so that it can be rotated around the bolt 4 or the Bolt 4 prevents the door or flap from falling out of the frame.
  • the door or flap means such as slopes, which presses the projection 4, here the bolt, when inserting the door or flap 1 in the outer frame 2 to the side and thereby biases.
  • the projection is congruent with the recess and / or indentation 8, it engages in this and thereby secures the door or flap 1 on the outer frame 2.
