European Patent Application Publication No. 2531669

The present invention makes it easy to open the general-purpose device mentioned at the beginning, even if the device is in particular the wall arrangement which may be desired, in which case the device preferably It is based on the objective of designing so that simplicity and cost efficiency should be maintained.

The above objects are achieved by the present invention, wherein the device is formed such that the first bracket mechanism is non-movably attachable to the open edge of the panel-like structural element, And a second bracket mechanism configured to be attachable to the closure cover and rotatably articulated on the first bracket mechanism, the at least two interacting brackets. This is because it has a mechanism.

The invention thus provides a pair of bracket mechanisms for the purpose of pivotally mounting the closure cover in a surprisingly simple manner with respect to the opening, in particular the edge of the inspection opening. Each bracket mechanism can be deployed in the manner of a fixture, and basically it is also possible for the device from the cited prior art to be modified with the bracket mechanism according to the invention.

The articulated connection may be substantially realized by a kind of hinge, in which case the detachable articulated connection may be realized by a pivoting shaft engaged around, for example, by a claw-like open bush or sleeve. .. However, it is also possible, for example, for the closed sleeve to be slid onto the angled projection. Here, in principle, a single combination of first and second bracket mechanisms may be sufficient.

A development of the device according to the invention is in each case provided with two pairs of first and second bracket mechanisms which can be assigned to the edges of the closure cover which are mounted on mutually opposite sides. Realize that. This results in a much more stable pivotable articulation of the closure cover, especially in any installed position of the device according to the invention.

According to the invention, the pivoting shaft can be arranged on the structural element or on the closure cover. A preferred embodiment provides for the pivotable arrangement of the second bracket mechanism relative to the first bracket mechanism such that the or one pivot shaft is on the second bracket mechanism, ie the closure cover. Realize that it is placed on top. This may facilitate the installation process, in particular due to the fact that the closure cover to be attached, which is in each case movable, has a male plug-in component. For example, a rotary shaft protrusion that projects radially outward from the edge portion can be inserted into a blind hole in the first bracket mechanism.

The development of the present invention realizes that the rotating shaft or a part of the rotating shaft is formed as a rotating protrusion that can be inserted into a guide track of the first bracket mechanism. In this case, too, the pivoting projection can project substantially radially, but is not axially inserted into the blind hole, instead the free end of the projection is placed in the guide track and blindly. It is inserted and placed laterally with respect to the axial direction of the hole. Here, the pivoting projection can also be the free end section of a continuous pivoting shaft, but the individual pivoting projection as a short member of the pivoting shaft is functionally suitable and It may be easier to manufacture. In particular, the rotating protrusion may be integrally formed on the second bracket mechanism. Additionally or alternatively, the guide track can be integrally formed on the first bracket mechanism. The guide track is preferably in the form of a guide groove.

In this way, according to the invention, it is particularly simple that each pivoting projection can be inserted into the guide groove in the simple installation process for the purpose of pivotally disposing the closing cover there. Achieved in a fashion, the closure cover, conversely, can likewise be removed at any time so that the opening is completely open and open.

Another development of the device according to the invention is, in a way that advances the invention, that the guide tracks deviate with respect to their contour from an orientation (surface normal) orthogonal to the opening to be closed. Realize that. As a result of this deviation of the guide track from the surface normal, the closure cover is additionally fixed in its end or pivot position, in particular to prevent accidental sliding or sliding out. Here, for example, the guide track can have a curvature. However, the preferred embodiment realizes that the contour of the guide track is oriented linearly and inclined with respect to the frame plane. In particular, in the case of a device according to the invention mounted on a wall, the tilting gradient can extend downwards, so that the pivoting projection slides into the guide track and remains there. Gravity can help.

It can also be realized that the pivoting projection can be locked in its final position within the guide track. This is especially the case if, for example, a plastic with a certain elasticity is used as the material, it overcomes a constriction or other curved path on the path of the pivoting projection into the guide track and then behind it. This can be achieved particularly easily by means of a pivoting projection which is itself locked to. More somewhat complex locking means such as locking spheres can also be easily used. Therefore, in any case, the closure cover can additionally be fixed in the pivoted position of its end. This may be particularly suitable for the arrangement of the device in the ceiling, but in the case of the arrangement in the ceiling simply the presence and nature of the deviation of the guide track from the surface normal may be advantageous. Is also a reality.

Another independent development of the present invention is characterized in that the pivoting protrusion is arranged on a center line of the closing cover.

If the pivoting projection, which acts as a pivoting shaft, is arranged near the edge on the closure cover, the closure cover is preferably in the case of a wall arrangement, into a space, or , Can be pivoted upwards or downwards towards the user, or else said closure cover is to the left or, in the case of a vertical pivot shaft orientation, to the right or left , Can be swung open. In a development of the invention in which independent protection is also claimed, the closure cover can be rotated through an angle of about 180° about a central pivot line with respect to itself, and preferably about. It can be opened by a pivoting movement with an angle of 90°. For this purpose, the closure cover can preferably be of a mirror-symmetrical form with respect to the axis of rotation because it is particularly well balanced with respect to weight, but for certain reasons it is so desired. However, it is not necessary for the closure cover to have a mirror-symmetrical configuration with respect to the axis of rotation, and the closure cover can also have, for example, a triangular shape, in which case the axis of rotation extends parallel to the base. Exists Similar considerations lead to the example that the pivot axis does not necessarily have to be exactly centered, but may also have a constant parallel offset with respect to the centerline. This has the advantage, for example, that the surfaces surrounding the device can form an opening stop for the closure cover, which can also be held or fixed there.

Basically, in the case of a structure with a pivoting shaft on or near the centerline, during the opening movement, in each case one compartment of the closure cover pivots outwardly and another compartment. Rotates inward. It is therefore possible or necessary for the arrangement of the pivot axis to take into account the spatial conditions for the pivoting movement behind the device, in particular the available free space. However, in any case, if the device is arranged on the wall, the advantage is that the compartment of the closure cover that opens towards the user is basically selectively pivoted downward or upward. Or it lies in the fact that it can be rotated to the left or to the right. This can also be useful in the case of a ceiling arrangement. The pivotability of the closure cover about the centerline or about a line near the centerline does not require, for example, a handle or other means to open the closed closure cover, rather the closure cover It also has the advantage that it can be easily opened and closed by pressing one of its compartments or the other. For locking in the closed position, for example due to the elasticity of the detent element, the closure cover is finally in its final end position, where it preferably terminates in a flush manner. It is also possible to envisage a pivoting movement slightly beyond the closed position, for example, if it springs back to its final position.

Each closure member can be manufactured from all possible and conceivable materials suitable for this purpose, for example metal, wood and the like. However, it is preferred that at least one of the bracket mechanisms, and preferably both bracket mechanisms, be manufactured from plastic. Thus, the bracket mechanism can be particularly easily integrally molded on one closing member, and the guide track can be preferably formed as a guide groove. Therefore, the device according to the invention can be easily transported in a standardized manner in large unit quantities, to have low weight, to be stable, to be reliable, to be robust. As such, it can be designed in a material-saving manner, such as with different colors or different decorations, and particularly inexpensively.

Similarly, modern plastics are readily recyclable, especially if only one type of plastic is selected and used, to achieve environmentally compatible sustainability.

In particular for stability or to avoid distortion, each plastic part may have, for example, stiffeners, ribs, flutes, etc. Visible surfaces can be veneered, coated, eg chrome plated, painted, paper clad, rivet tacked, grained, grooved, etc. if desired. .. In particular, in sky-finished buildings, insulation, for example by a pattern of holes, or acoustic damping may also be involved. The device according to the invention can also be integrated and technically and/or visually integrated in this respect as well.

With the device according to the invention, it is possible, if desired, that the device can be aesthetically emphasized or designed to be particularly unobtrusive as if it were "invisible". And the latter option is generally preferred.

As the plastic material, various plastics can be used, in particular, acrylonitrile-butadiene-styrene copolymer (ABS plastic), or other thermoplastic material and/or styrene copolymer. Such plastics can in particular be coated with paint and bonded with an adhesive. According to the invention, adhesives and additional mechanical fasteners are preferably used for connecting the plastic parts to the empty-finished building element. For mechanical fasteners, staples, clips, crimps, clamps, pins, rivets, etc. may be used. For example, flutes or the like may also be provided to increase the bond area. For example, as fastening elements, staples or clamps are preferred over nails, since they relate to the head-sized parts, for example into empty-finish building materials with gypsum components. This is because the abutment bridge that does not lose its footing by being easily penetrated is formed.

A further development of the device according to the invention is characterized in that at least one closure setting element is provided which predefines the closed position of the closure cover. A variety of strategies and embodiments are possible for this purpose. One preferred embodiment realizes that the closure setting element is in the form of or has a friction engagement element. In a particularly simple manner both in terms of function and manufacture, such a frictional engagement element according to the invention not only establishes the positioning of the closed position, but also assists in the realization of fixing in the closed position. In the case of devices formed from plastic, for example, by means of pillars, granular surfaces, flutes or the like, or simply by area friction with a constant coefficient of friction, to interact, for example a bracket on the structural element. Functionally interacting friction surfaces may be formed on the mechanism and on the bracket mechanism on the closure cover. The frictionally engaging elements may be arranged, for example, in the vicinity of the pivoting projection.

For example, it is easily possible that a plurality of closure setting elements are provided in the same or different pairs. These can be arranged at the free edge of the opening and/or at the edge on the pivoting projection side. Here, the occlusion setting element, or one or more occlusion setting elements, can be or have one stop element or a plurality of stop elements. It may additionally or alternatively be realized that the above or at least one closure setting element is in the form of or has a locking or restraining element. This can be achieved, for example, by means of elastic fitting action, locking or detent elements. A particularly simple but reliable elastic-fitting action element can be realized, for example, by using an elastic plastic with a receiver or guide whose cross-section is narrowed for locking the projections. For example, a spring tongue on the closure frame simultaneously acts as a stop element projecting into the closure frame opening, said spring tongue being provided for reversible locking of its spring end, It is possible to lock in a kind of channel of a closure element which functionally interacts with the spring tongue on the closure cover. It is easily possible that a sliding or pivoting bolt or latch is provided.

According to the present invention, for the closure setting element, a dedicated bracket mechanism, preferably a pair of two bracket mechanisms, is provided for mounting the structural element and the closure so as to be mounted to face each other. It is expediently realized that two bracket mechanisms are provided which are assigned to the cover and which interact functionally. Therefore, each bracket mechanism is separately provided with respect to the bracket mechanism for the above-mentioned rotation projection. In particular, if the two pivoting projections on the center line of the closure cover cooperate to form a pivoting shaft and are arranged on two opposite edges of the closure cover, Each closing bracket mechanism, i.e., in particular a stop and/or restraining and/or locking element, can be assigned to the third side of the closure cover.

Another development of the invention is that at least one of the bracket mechanisms, preferably all of the bracket mechanisms, has at least one frictional engagement and/or deterministic engagement element for its attachment in the device. , Preferably with a fastening alignment pin.

The bracket mechanism may be provided in the form of a mount that can be fastened to the panel-like element, for example a plasterboard. In a development according to the invention, the bracket mechanism may preferably be mortise-spliced into the blind holes in the respective panel-like element. Alternatively or additionally, other fastening means such as screws, nails, clamps or adhesives etc. may be used. Such fastening alignment pins, or other constant frictional engagement and/or deterministic engagement elements may be integrally molded onto the bracket mechanism, especially from plastic.

Another development of the invention is that at least one of the bracket arrangements is preferably at least one pair, one intended for placement on the structural element and one intended for placement on the closure cover. The bracket mechanism is a mutually angled abutment surface, one abutment surface is provided for abutment on the rear side and the other abutment surface is provided for abutment on adjacent edges. To have an abutting surface that is provided. In this way, the bracket mechanism may be engaged and embedded in a substantially L-shaped fashion around the edge region of one panel-like element. At the same time, the material of the bracket mechanism is barely visible in the closing gap between the panel-like elements. The bracket mechanism may preferably be formed in the form of a table-shaped part, and for example, the pivoting protrusion may be carried and stably supported on the table-shaped part of the type described above.

Another development of the device according to the invention is that the structural element having the opening is a frame surrounding the opening, while being insertable into a recess or notch in a panel-shaped structural element. Or in the form of a frame that is attachable to a panel-like structural element.

Therefore, in accordance with the present invention, a fully functional inspection opening with its own frame and closure cover is manufactured in the factory, which inspection opening is simply suitable for use in an empty finished building structure at a construction site. Is particularly preferably realized. On the other hand, this proper insertion of the device can be considerably simplified if the material for the frame substantially corresponds to the material of the panel-like structural element in which the frame is intended to be inserted. .. Therefore, the inspection opening does not have to be prepared on its own at the construction site with its closure cover, but rather provided with a simple notch elsewhere to insert the frame of the already professionally prepared device. It only needs to be done. However, this is also easily possible at the construction site, especially by unskilled personnel, since in its essence such a work step is another work step during the construction of an empty-finish structure. Is not different.

Another development of the device according to the invention is characterized in that the frame and/or the closure cover have substantially the state and material thickness of an empty finished building panel material. The material for the frame and/or the closure cover may preferably be substantially gypsum. In this way, the device according to the invention is particularly preferably such that it is unobtrusive, associative and flush with, into empty-finished building structures using substantially the same or similar materials. It can be designed so that it can also be integrated in a fashion that is also seamless.

In particular, a further development of the invention is characterized in that the frame is manufactured from a subregion or compartment of a panel-shaped structural element. As already discussed above, this particularly preferred development of the device according to the invention preferably results in the inconvenience of apertures, which can be implemented inaccurately with respect to the frame in the panel-like structural element. The effect is that the device can be fitted into an empty-finished building structure at the construction site, without sharp sawing or other cutting, i.e. even using conventional building methods in a particularly free manner. The frame prefabricated according to the invention (along with the closure cover and the inspection opening itself) only needs to be provided as a section of a structural element, so that it is connected in a conventional manner to another structural element. Together, it need only be suitably finished.

As already discussed further above, even in the case of the device according to the invention provided for a ceiling arrangement, for example due to the design of the guide track, a separate capture means for the closure cover is provided. May be unnecessary. However, nevertheless, according to a development of the invention, at least one catch element for catching the closure cover is provided in order to prevent the closure cover from falling in an uncontrolled manner when opened. In addition or alternatively, it is possible. Cables, clips, springs, guide rails, articulated and/or telescopically connected rods, etc. may be used for this purpose.

A further development of the device according to the invention is characterized in that the bracket mechanism is provided as an assembly kit. Advantageously, the device according to the invention for a frame with an inspection opening and a closing cover that fits into the inspection opening eliminates the need to carry out difficult working steps on the construction site. In addition, and to ensure control quality for inspection flaps, it can be provided prefabricated in a factory in an industrial, functionally reliable manner. The device thus pre-fabricated is then (preferably also already factory-equipped) mounted for each bracket mechanism using the assembly kit preferably provided according to the invention, and blank finished. Can be inserted in a simple and inexpensive manner using different conventional working steps, in a particularly discreet manner, within the building structure of the invention.

The assembly kit is preferably such that two pairs are provided for pivotable articulation of the closure cover and one pair is provided for fixing the closed position of the closure cover. It has a pair of bracket mechanisms.

An opening is formed in at least one panel-like structural element and can be closed by a panel-like closure cover, in particular for a wall or a ceiling, for closing an opening in a preferably empty-finished building structure, in particular an inspection opening To an assembly kit or mounting kit for a device according to the invention, characterized by at least one bracket mechanism according to the invention for deployment and assembly of the assembly kit. However, independent protection is claimed. Assembly kits of the above type can basically also be provided for retrofitting purposes.

Although each figure illustrates a representative embodiment in which further inventive features may be found, each embodiment should basically be regarded as merely an example, and the subject matter of the invention or its protection is effective. It is not intended to limit the scope.

FIG. 1 shows a representative embodiment of a device according to the invention, in particular a plan view of its rear side rather than its front side.

The device according to the invention for closing the inspection opening has a frame 1 framing the inspection opening 2 and a closing cover 3 for closing the inspection opening 2.

The closing cover 3 is connected to the frame 1 by four different types of bracket mechanisms.

First, on the closure cover 3, a plurality of bracket mechanisms 4 are arranged, in each case having one pivoting projection 5 projecting outward from the closure cover 3. The bracket mechanisms 4 are arranged as a pair, and the respective bracket mechanisms 4 are arranged on the edges of the closure cover 3 which face each other. The pivoting projections 5 are aligned with each other and cooperate to form a pivoting shaft for the closure cover 3 along one of the virtual centerlines of the closure cover.

Each of the rotation projections 5 is inserted into the guide groove 6 of each bracket mechanism 7 for mounting the shaft. Each bracket mechanism 7 is also provided as a pair, and is arranged on the frame 1 so as to face the bracket mechanism 4, respectively.

A locking mechanism is arranged at the third edge of the closure cover 3 to lock it in the closed position of the closure cover 3 shown in FIG. The locking mechanism consists of two additional bracket mechanisms 8 and 9. The bracket mechanism 8 has a locking spring tongue 10 which can be locked in the locking receiver 11 of the bracket mechanism 9.

Taking the bracket mechanisms 8 and 9 as an example, at one location, the fastening alignment pins are shown as small circles 12, otherwise each fastening alignment pin is not visible in FIG. At the appropriate blind holes in the frame 1 and the closure cover 3 downwards into the plane of the drawing for fastening by deterministic and frictional engagement of the respective bracket mechanisms 8, 9. It is inserted inside. The other bracket features 4, 7 each have a corresponding fastening alignment pin.

The bracket mechanisms 4, 7, 8, 9 are preferably molded from plastic into a single piece.

Further details and features are shown in the following figures in which the same structural elements are represented by the same reference numbers as in FIG.

FIG. 2 shows a perspective view of the bracket mechanism 4 having its own rotating projection 5.

The bracket mechanism 4 has a base plate 13 which can be mounted on the closure cover 3 according to the illustration in FIG. 1 by means of an abutment surface 14 visible in FIG. For this purpose, each fastening alignment pin 15 of the closure cover 3 is abutted until the abutment surface 14 abuts against the closure cover 3 and the bracket mechanism 4 is fixedly fastened to the closure cover 3. Pressed into the blind hole. The fastening alignment pin 15 has a surrounding contour 16 that enhances the frictional engagement effect within the blind hole, which may be formed in a scale-like manner for the barb effect, for example. The fastening can be ensured by an adhesive and/or mechanical fastening means.

From the base plate 13, a table-shaped portion 17 carrying the rotation protrusion 5 projects. The base plate 14 cooperates with the table 17 to form a substantially L-shaped profile which can engage or tightly fit around the edge of the closure cover 3. However, the table 17 has flanks 18 that can be further engaged in a positive engagement manner in a suitable recess in the edge of the closure cover 3.

FIG. 3 shows a perspective view of a bracket mechanism 7 according to the invention with a guide groove 6 for the pivoting projection 5 according to FIG.

The guide groove 6 is integrated in the table-shaped portion 17 and is integrally molded. It can be seen that the guide groove 6 extends obliquely with respect to the base plate 13. In the illustration of FIG. 1, the guide grooves are preferably such that the respective pivoting projections 5 guided respectively under the gravity of the closure cover 3 into the guide grooves 6 and possibly to their ends. It is slanted deeply and extends downward with an inclination into the plane of the drawing. Prior to its end, the guide groove 6 can be narrowed, or the guide groove can be additionally locked to the turning projection 5 behind the bend by the application of a constant force. It may have other constant turns.

The base plate 13 with its abutment surface 14, the bracket 13 with its flank 18, and the fastening alignment pin 15 with its contour 16 are used in the same way as in the bracket mechanism 4. However, only that the bracket mechanism 7 is fastened to the frame 1 and not to the closure cover 3 is excluded.

4 shows a perspective view of a bracket mechanism 8 according to the invention with a locking spring tongue 10 for locking the closure cover 3 of the device according to FIG. 1 in the closed position.

Furthermore, the bracket mechanism 8 also has a base plate 13 with an abutment surface 14 for the closure cover 3 and a fastening alignment pin 15 with a profile 16.

Arranged on the base plate 13 is a locking spring tongue 10 which, if a plastic material is used, can be formed with elastic properties depending on the material properties and its dimensions. The end of the locking spring tongue 10 is formed as the locking element 19 itself. Due to the folding back 20, the locking element is in the form of a double layer U with two locking legs 21 and 22. The legs 21 and 22 are mutually connected (for example, simply between the thumb and forefinger of the hand, or with a tool such as the flat head of a screwdriver, or with small pliers). So that they can be pressed close together and the legs can spring back to the rest position shown in FIG. 4 with a relatively large distance relative to each other after the application of pressure has been released. Moreover, the locking element 19 is also elastic in nature in nature. On the outer side of the locking leg 22 there is arranged a thick bead or ridge 23 which extends laterally with respect to the contour of the locking spring tongue 10.

Before the locking and unlocking process is discussed in further detail in the functional section, FIG. 5 will first be discussed.

The bracket mechanism 9 shown in the perspective view in FIG. 5 also firstly has a base plate 13 with an abutment surface 14 for the frame 1 and a fastening alignment pin 15 with a profile 16.

However, in addition, the bracket mechanism 9 also has a locking receiver 11 formed in the exemplary embodiment in FIG. 5 simply as a slot 24 formed into the base plate 13. In this exemplary embodiment, a remnant strip 25 of base plate material that remains adjacent to the slot 24 is essential for the locking action.

Next, based on FIGS. 4 and 5, the locking and unlocking process may be discussed in more detail.

During closing of the closure cover 3, i.e. when the closure cover 3 is placed in the closed position shown in FIG. 1, the locking element 19 causes the ridge 23 to engage behind the residual strip 25. Therefore, it is finally pressed into the slot 24 until it locks the closure cover 3 in the closed position. For this purpose, it is not necessary for the locking legs 21, 22 to be additionally pressed against one another. Rather, this means that when the locking element 19 is pressed deep enough into the slot 24, V-shaped or locking legs 21, 22 conically extending from the fold 20 towards each other, It occurs automatically due to the elastic properties of those materials.

For only the unlocking action, the ridge 23 is released again from the residual strip 25, and the locking element 19 as a whole is completely withdrawn from the slot again, as a result of which the closure cover 3 pivots. The locking legs 21, 22 should be pressed together in the manner described above until they can be opened.

As a reminder, the frame 1 may also be added below the slot 24, requiring a recess or other constant free space for receiving the locking element 19 in the closed position. It is also possible for the slot 24 to extend beyond the inner edge of the frame 1, i.e. into the inspection opening 2, in which case this would result in the closed cover 3 in the closed position. Resulting in an undesirably large gap distance between the frame 1 and the frame 1. However, other locking or restraint means can also be easily envisioned. For example, a pivoting catch can be provided on the frame 1 in the closed position of the closure cover 3 and beyond the edge of the closure cover 3 into the catch receiver. However, in the exemplary embodiment shown, the closure cover 3 can be automatically locked at the same time that it is particularly easily pressed and closed.
