Definitions
- the present invention relates to an inspection flap for drywall and ceilings according to the preamble of claim 1 and a method for assembling the inspection flap according to claim 23.
- Generic inspection flaps are used to ensure accessibility to rooms behind ceilings or walls, for example to be able to reach measuring devices for water or heat, as well as shut-off devices for drinking water or heating installations, in or behind drywall walls or ceilings. They are known from the prior art in a wide variety of configurations.
- the object of the invention is to solve these problems.
- an inspection flap for drywall and ceilings is created with a frame in which a door leaf is hinged movably, in particular rotatably, by one or more door hinges, the door leaf having a first locking means and a second locking means, the first locking means is designed as a lock-like acting bolt, wherein the bolt can preferably be actuated with a tool or a key. and wherein the second locking means comprises at least one pivot handle acting like a bolt.
- the swivel handle (s) provides an additional possibility beyond the first locking means to securely lock the inspection flap.
- the door leaf has at least one to a maximum of six, particularly preferably at least two and a maximum of four lever-like and bolt-like swivel handles.
- the respective pivot handle has a lever section on which a handle section is integrally formed, the pivot handle being pivotably mounted on the door leaf in the area of the lever section. Furthermore, a safe way to manually open or close the revision flap is created, because without such swivel handles, a tool such as a square wrench or a (security) key is the only way to open the inspection flap by hand, with the tool or key first must be tilted in the lock mechanism of the door leaf in order to build up enough friction so that the tool or key does not slip out of the lock mechanism, especially during the opening process of the door leaf, which would hinder the opening process of the inspection flap.
- a tool such as a square wrench or a (security) key is the only way to open the inspection flap by hand, with the tool or key first must be tilted in the lock mechanism of the door leaf in order to build up enough friction so that the tool or key does not slip out of the lock mechanism, especially during the opening process of the door leaf, which would hinder the opening process of the inspection flap.
- the respective pivot lever in particular the lever portion of the respective pivot lever, in a locked state is preferably predominantly received in a gap or a rebate space that is formed between tween the frame and the closed and locked door leaf. This ensures a visually appealing visual impression of the closed inspection flap, which is virtually not adversely affected by the second locking means.
- the handle section can be visually recognizable, it is preferably designed to be relatively small so that it does not change the appearance significantly.
- the first and the second locking means thus preferably have a different structure.
- pivot handle in the area of the Hebelab section - for example simply via a rivet - is pivotably mounted on the door leaf. This advantageously creates a mounting of the swivel handle that is easy to manufacture.
- lever section of the swivel handle has an engagement means and that a counterpart handle means is provided on the frame for cooperation during locking.
- the engagement means is designed as a link open on one side and that the counter-engagement means is designed as a projection, in particular a press-in nut for engaging the link.
- Kinematic reversals of this principle are conceivable.
- the link has a cam which forms a type of locking lug, so that the counter-engagement means, in particular the Press-in nut, latched in the gate during the locking process of the door leaf by the respective swivel handle, so that the counter-engagement means remains securely in the gate during the locking process of the door leaf by the respective swivel handle.
- a Rastpo position with a secure hold is structurally simple and therefore advantageous.
- the lever section of the respective swivel handle has a curved edge area which is shaped like a clamping eccentric or a tension spiral which, in cooperation with an abutment on the frame, can bring the swivel handle into a clamped state.
- An advantageously high contact pressure with which the door leaf is locked against the frame by the swivel handle can thus be achieved via the curved edge area.
- the frame is composed of several angle profiles. This creates an easy-to-manufacture and therefore advantageous construction of the window frame.
- the angle profiles are connected in a combined form-fitting and material-locking manner. This creates a safe and therefore permanent connection between the angle profiles.
- angle profiles are interlocked with one another by means of a dovetail connection machined into a first leg of the respective angle profile. This creates a flat form-fit connection that is easy to manufacture.
- a material connection of the angle profiles takes place in each case by welding through an I or a fillet weld at a joint of a respective second leg of the respective angle profile.
- the frame has a corrosion protection coating, which is preferably produced by a zinc layer. This can preferably be supplemented with a powder coating. This creates a particularly resistant corrosion protection is advantageous.
- the first locking means is designed according to a first type and the second locking means is designed according to a second type. As a result, two different locking means are made available, which can be used advantageously depending on the requirements.
- first type of the first locking means differs from the second type of the second locking means.
- two differently constructed and working locking means are made available, which can be used depending on the functional requirements and space requirements.
- the window frame has at least one assembly aid that is attached to a side of the window frame facing away from the opening.
- the assembly aid can be designed as an assembly aid bracket.
- the auxiliary mounting bracket can be supplemented or replaced by one or more mounting anchors.
- the auxiliary mounting bracket -or an analog element- is attached with one leg on the outside of the frame and preferably projects with a further leg angled to the outside of the frame and when inserting the frame is placed in an opening on the back of the drywall or - cover the wall there, especially the drywall structure, and hold the inspection flap or frame - supported by just one hand - in the desired position for further assembly.
- the assembly aid is bent from a flat material, the thickness of the flat material being selected so that the mounting angle can be bent by hand, i.e. without the aid of a tool, to the required wall or ceiling thickness.
- the assembly aid can be bent to the appropriate size before geous on the construction site or during assembly, without the need for special tools.
- the frame has several assembly claws, via which the frame is supported or can be clamped on the reveal in the opening provided for the frame in the drywall or ceiling. This provides a simple, effective way to fit the Blendrah men during assembly with regard to the installation position still within limits changeable in the intended opening of the drywall or ceiling.
- the frame has several wall anchors, with which the frame can also be attached to a stand or support structure of the drywall or ceiling.
- the blend frame several clips, in particular Christmas tree clips, which also serve to make a gap that is formed as evenly as possible in the closed state of the inspection flap between the blend frame and door leaf.
- the respective fir tree clip has a curved geometry and is preferably made of a plastic material. This results in a functionally advantageous and easily producible geometry of the Christmas tree clip.
- At least one or more, in particular up to four, drywall panels are attached to the frame.
- the number can be based, for example, on a desired fire protection class of the inspection hatch.
- an advantageously simple means is available with which the fire protection class of the inspection flap can only be changed when the inspection flap is installed by the manufacturer, as required. This advantageously saves different variants of the window frame with regard to its fire protection flap.
- the door leaf has an anti-corrosion coating, which is preferably produced by a zinc layer. As a result, permanent corrosion protection is advantageously created.
- the first hinge is formed by a press-in bolt which is fastened to the door leaf, the press-in bolt engaging in a geometrically corresponding opening in the frame. This results in a hinge that is simple in terms of design and manufacturing technology.
- the second hinge has a spring pin lock which can be brought manually from a working position into an unlocked position.
- the door leaf can be removed from and attached to the frame easily and without having to study an operating manual - clearly recognizable and self-explanatory for an inexperienced user.
- the invention also provides an assembly method for assembling a revision flap (1) in a ceiling opening, characterized by the following method steps:
- Clipping assembly aids in particular onto dome-like press-in nuts, and, if necessary, securing the assembly aids;
- this method can, for example, have the following advantageous further steps:
- step 50 the door leaf is unhooked from the frame of the inspection flap, in particular by releasing an angled leg of the spring pin from the opening in the door leaf provided for this purpose and the door leaf is lifted or pulled out of the corresponding opening of the Blendrah mens with the press-fit bolt.

- Fig. 1 shows an inspection flap 1 according to the invention in a spatial presen- tation.
- the inspection flap 1 has a frame 2.
- the frame is composed of several profiles. This can be configured as angle profiles 3a, 3b, 3c, 3d.
- the angle profiles 3a, b, c, d can be made of a flat material such as sheet steel. Bending or roll forming are available as a first process for the angle profiles 3a, b, c, d.
- the frame 2 can have an anti-corrosion coating, which is preferably produced by a zinc layer.
- the zinc layer can either already be applied to the sheet metal from which the angle profiles 3a, b, c, d are made, or it can be produced, for example, by electroplating the angle profiles 3a, b, c, d or the joined frame 2.
- the angle profiles 3a, b, c, d can have an additional coating, which can advantageously be designed as a powder coating .
- connection of the angle profiles 3a, b, c, d to one another to form the frame 2 can - as shown in FIG. 1 - be carried out in a combined form and material fit.
- a form-fit connection of the angle profiles 3a, b, c, d with one another can - as shown in FIG. 1 and FIG. 2a - by means of an incorporated into a first leg 4a, b, c, d of the respective angle profile 3a, b, c, d
- Dovetail connection 5a, b, c, d take place.
- the dovetail-like connection 5a, b, c, d can also be present several times per angle profile 3a, b, c, d.
- a swallow's tail joint is a joint where the shape of the spring, prongs, or tenon is vaguely pronounced of the forked shape of a swallow's tail.
- the term "dovetail” is to be interpreted broadly here. In this respect, a form-fitting connection is also to be subsumed under the term “dovetail connection”, in which the corners of the dovetail are rounded or rounded, similar to a puzzle piece.
- connection not only has a positive-fit effect across the "dovetail", but also in its longitudinal direction.
- An undercut of a positive shape or a projection and a geometrically corresponding undercut of a negative shape or a recess are characteristic as a feature of such a form-fit connection.
- Such a connection is made in the third direction, which is also perpendicular to the "dovetail".
- the dovetail-like connection 5a, b, c, d can each be formed from a dovetail-like bulge and a contour-congruent cutout in which the dovetail-like bulge engages.
- Both geometry elements are incorporated into the respective angle profile 3a, b, c, d in such a way that there are no right and left angle profiles 3a, b, c, d in relation to the frame 2 to be joined.
- component variants are advantageously saved, so that four identical angular profiles 3a, b, c, d are used here for the construction of the window frame 2 - which is designed here to be square, for example.
- a material connection of the angle profiles 3a, b, c, d can be welded, for example, by an I-seam or a fillet weld at a joint of a respective second leg 6a, b, c, d of the respective angle profile 3a, b, c, d take place.
- the frame 2 is intended to be inserted in a section of a drywall or ceiling and to be attached to a soffit or a stand or support structure of the drywall or ceiling.
- the frame 2 has at least one assembly aid 7 (see FIG. 1 a and the illustrations in FIG. 7), which is attached to the second leg 6a, b, c, d of one of the angle profiles 3a, b, c, d can be fastened on a side of the frame 2 facing away from the opening.
- the assembly aid 7 is designed here as an assembly aid bracket. With one leg it projects laterally outside over the frame, preferably parallel to its plane of extension.
- the at least one mounting means 7 can also be attached to an upper side of the Blendrah mens 2.
- the assembly aid 7 can be designed as a wall anchor, for example.
- the auxiliary mounting bracket can also be supplemented with one or more wall anchors.
- the assembly aid 7 serves to simplify assembly, in particular when the inspection flap 1 is installed overhead or in the ceiling. When the window frame is inserted, the assembly aid 7 rests against the drywall structure on the back of the drywall or ceiling and holds the inspection flap 1 or the window frame 2 - supported by only one flange - in the desired position (see again the representations in Fig 7).
- the assembly aid 7 - here designed as an assembly aid bracket - can be bent according to an advantageous embodiment from a flat material -preferably sheet steel-, the thickness of the flat material preferably being selected so that the assembly aid 7 from Fland -therefore without the aid of a tool- can be used (required) measure of wall or ceiling thickness can be bent.
- the assembly aid 7 can be fastened to the frame 2 by fastening means, for example by rivets or the like.
- the outer frame 2 can preferably also have several assembly claws 8 on its outer circumference, via which the outer frame 2 is supported on the reveal in the opening provided for the outer frame 2 in the drywall or ceiling or via which it can be clamped.
- the Monta claws 8 can each be arranged on the side of the window frame 2 facing away from the opening on the outer circumference of the sen.
- the fastening of the respective assembly claw 8 on the frame can be done with a wide variety of fasteners. Before given it takes place in each case by a press-fit nut 9, which has a dome-like geometry and which then protrudes into the opening of the Blendrah mens 2 through its dome-like geometry.
- press-in nut 9 another fastening means for fastening the respective mounting claw 8 to the frame 2, such as a weld-on nut, can also be used.
- a nut can also be used, which is connected to the frame 2 by a joining method other than pressing in or welding.
- other names of the mother which indicate the corresponding joining process, are to be understood as synonymous with the press-in nut 9.
- a particularly advantageous feature of the press-in nut 9 is therefore not the type of joining process with which it is attached to the frame 2, but rather - in addition to its internal thread - its dome-like geometry.
- the outer frame 2 can also have several wall anchors 10 in an advantageous embodiment, with which the outer frame 2 can also be attached to a stand or support structure of the drywall or ceiling.
- the respective wall anchor 10 can be fastened to the frame 2 on its side facing away from the opening, for example by fastening means, in particular by one or more rivets.
- the wall anchors 10 are shown each applied to the frame 2.
- the wall anchor 10 is rotated around the fastening rivet, for example by 90 °, for fastening the frame 2 to the stand or supporting structure of the drywall or ceiling, as shown in FIG. 2d or in FIG. 4c.
- the frame 2 can have several so-called tan tree clips 11.
- the respective fir tree clip 11 can have a curved geometry and is preferably made of a plastic material.
- the fir tree clips 11 rest on a reveal of the opening in the drywall or ceiling and thus serve as a support and reinforcement for the window frame 2.
- one or more drywall sheets can be attached to the rear.
- the number of drywall 12, 13 can be varied, for example between one and four. It can be based on the desired fire protection class of the inspection flap 1.
- the drywall panels 12, 13 wei sen then optionally openings that correspond geometrically to an opening that the frame 2 forms (Fig. 3a, b).
- the inspection flap 1 also has a door leaf 14. This can advantageously be designed in the manner of FIG. 2c.
- the door leaf 14 is beat on the frame 2 by one or more, preferably by at least two door hinges 15, 16 is rotatable. In the figures, it is an example of the right on the window frame.
- the opening of the window frame 2 of the inspection flap 1 can be opened and closed with the door leaf.
- the door leaf 14 can also be produced from a flat material, preferably from a sheet steel. Fierstell compiler for the door leaf 14 is, for example, folding.
- the door leaf 14 can also have an anti-corrosion coating, which is preferably produced by a zinc layer.
- the first, here lower hinge 15 is formed by a press-in bolt 17 which is fastened to the door leaf 14 (see FIGS. 2a to d, in particular FIG. 2c).
- the A press bolt 17 then engages in a geometrically corresponding opening in the frame 2 a.
- the second, here upper hinge 16 can have a spring pin bar 18 which can be brought from a working position into an unlocked position.
- the to angled, spring-loaded spring pin bar 18 is pulled down so that it no longer engages in the ge ometrically corresponding opening in the frame 2.
- This unlocked position of the spring pin bar 18 can be retained for easy unhooking of the door leaf from the frame 2 by an angled leg 19 of the spring pin bar 18 is snapped into a designated opening of the door leaf 14.
- the door leaf 14 can also be hinged on the left of the frame.
- the symmetrical door leaf 14 is rotated by 180 ° so that the first hinge 15 is at the bottom and the second hinge 16 with the spring pin bar 18 is at the bottom.
- the door leaf 14 has a first locking means.
- the first locking means is designed according to a first type. This can be configured as a lock-like bolt 20 (Fig. 2c).
- the bolt 20 can engage in a corresponding trap which is incorporated into the frame 2.
- the bolt 20 can be operated with a tool such as a square wrench.
- the bolt 20 can have a lock mechanism 21 which can have a pin, for example a square pin, that corresponds geometrically to the tool.
- the lock mechanism 21 can also form a locking cylinder which can be actuated with a corresponding key, as shown in FIG. 2c.
- the door leaf 14 can also have a second locking means.
- the second locking means is designed according to a second type.
- the first type of the first locking means differs from the second type of the second locking means.
- the door leaf 14 can have at least one or more, preferably two or four, of this second locking means of the second type (see FIG. 2c), which are each designed here as lever-like swivel handles 22 (FIG. 3a).
- the respective swivel handle 22 is used for additional locking of the door leaf 14 on the frame 2 and can also be used for safe manual closing and opening of the door leaf 14 or the inspection flap 1.
- the respective pivot handle 22 has a Flebelabrough 23 on which a Griffab section 24 - here in one piece - can be formed.
- the pivot handle 22 can be pivotably mounted on the door leaf 14 via a rivet in the area of the Flebelabites 23.
- the handle section 24 can be bent over at right angles to the fleece section 23. It is preferably designed to be relatively small so that it can be gripped but hardly affects the optics. He can hen something vorste from the gap and rest on the door leaf 14 or the frame 2 (Fig. 3b).
- the flebel section 23 of the respective swivel handle 22 can also have a gate 25. This can be open on one side.
- the link 25 is brought into operative connection with a countermeasure on the frame, for example the dome-like press-in nut 9, which creates the pivot point of the lever, the press-in nut 9 successively engages in the gate 25.
- the gate 25 can have a cam 26 (FIG. 3 a), which forms a type of locking lug, so that the dome-like press-in nut 9 remains securely in the gate 25 during the locking process of the door leaf 14 by the respective swivel handle 22.
- the Flebelabites 23 of the respective pivot handle 22 can also have a krümm th edge region 27, which can be shaped in the manner of a clamping eccentric or a clamping spiral. A correspondingly high pressing force on the door leaf 14 can thus be achieved via the curved edge region 27, with which the door leaf 14 is locked against the frame 2 by the swivel handle 22.
- the lever section 23 remains virtually invisible from the outside in a gap or a rebate space which is formed between the frame 2 and the closed and locked door leaf 14. Only the relatively small handle section 24 remains visible from the outside, see also FIG. 3b.
- swivel handle (s) 22 By or the swivel handle (s) 22 a further -second - locking means of the second type is created, with the tool or keyless the revision flap 1 can be safely locked.
- the lock mechanism 21 of the door leaf 14 has to be tilted in order to build up enough friction so that the tool or the key does not slip out of the lock mechanism, especially during the opening process of the door leaf 14, which would hinder the opening process of the inspection flap 1.
- one or more, here two, drywall panels 28, 29 can be fastened to the door leaf 14 - analogously to the frame 2 - on its side facing the opening.
- the number of drywall panels 28, 29 can be varied between one and more and can vary according to the desired fire protection class of the inspection flap
- the inspection flap 1 can also optionally have a safety chain 30:
- the safety chain 30 - implemented here by a wire rope - can have a snap hook 31, 32 at both ends, which is hooked into a hook 33, 34.
- the first hook 33 is attached to the frame 2, while the second Ha ken 34 is attached to the door leaf 14.
- the inspection flap 1 can have two or more - here two - assembly aids 35.
- the assembly aid 35 is preferably made from a plastic material in an injection molding process.
- the assembly aid 35 which is shown enlarged in Fig. 5d, has a jump 36 on which the frame 2, more precisely on its respective second leg 6a, b, c, d, after which the respective assembly aid 35 is clipped onto the respective press-in nut 9.
- the assembly aid 35 has a half snap cylinder 37 for clipping on.
- the assembly aid 35 also has a handle-like opening 38.
- the assembly aid 35 has a supporting leg 39, which is intended to be applied flush with the lower edge of the drywall or ceiling.
- a first assembly step 50 the door leaf 14 - if it is already vormon benefits - unhooked from the frame 2 of the inspection flap 1, in which the angled leg 19 of the spring pin bolt 18 is released from the intended opening of the door leaf 14 and the door leaf 14 from the lower, with the press-fit bolt 17 corresponding opening of the window frame 2 is lifted.
- the assembly aid 7 can be bent (e.g. by hand, i.e. without a special tool) to the thickness of the drywall ceiling in which the inspection flap 1 is to be assembled.
- a common thickness of the drywall ceiling is 40 to 50 mm.
- the frame 2 can first be passed through the opening provided for in the drywall ceiling and then hooked in (see FIGS. 5a and 5b).
- the hanging can be done by placing the assembly aid 7 on the side of the drywall facing away from the room (see FIG. 5c).
- the frame 2 only has to be held in the assembly position with one flange during the following assembly steps, while the other flange of a fitter can advantageously take on other assembly tasks.
- the assembly aids 35 can be clipped onto the dome-like press-in nuts 9 and secured in each case by screwing a threaded pin into the respective press-in nut 9 (see FIG. 5c). This is possible for a single fitter without outside help or additional aids, since the advantageous function of the assembly aid 7 means that he has a flange free for this purpose.
- the assembly aids 35 connected to the frame 2 with their respective support legs 39 can be positioned flush with the underside or room side of the drywall ceiling.
- wall anchors 10 can be brought into the assembly position and attached to the stand or supporting structure of the drywall ceiling who (see Fig. 4a). This is also possible for a single fitter without outside help or additional aids, since he has one hand free for this due to the advantageous function of the assembly aid 7.
- the edge area of the window frame 2 of the inspection flap 1 can be filled with filler after its installation in the drywall ceiling and smoothed with appropriate hand tools.
- the door leaf 14 can be rotatably hung into the frame 2 via the press-in bolt 17 and the spring pin bar 18 and secured by the safety chain 30 against accidentally falling out of the frame 2 (see Fig. 4b and Fig. C) .
