Moldings device

Description:

The invention relates to a profile strip device, in particular frame profile strip device, for example for producing a revision device, with a first profile strip and a second profile strip, wherein the second profile strip engages with at least one mounting head in at least one receptacle on the first profile strip.

Moldings are generally used in the construction sector for enclosing or delimiting, for example, floors as dividing strips, for windows for stabilization, for the production of frames, etc. As the name suggests, profile strips are characterized by their strip character and additional profiling. It is very particularly preferred to produce frames with the aid of such profile strip devices, ie frames for covering wall, floor or ceiling openings. An example of a generic profile strip device is described in DE 20 2008 001 831 U1. The same goes for DE 20 2007 001 538 U1.

In the prior art, the profiled strip device serves, for example, to produce an inspection cover and / or a revision frame of a revision device. In this case, a planking using the second profile strip or a fastening device is fixed. This usually happens at the factory.

Sometimes, however, there are also requirements to replace the planking or to install it on site, ie at a construction site, in the respective inspection cover or on the inspection frame. This is difficult to achieve with the fastening device according to DE 20 2008 001 831 U1 because it has to be first brought into the working position by an operator and then connected to the planking. With regard to DE 20 2007 001 538 U1 it is noticeable that, depending on the thickness of the planking, differently constructed fastening devices must be used as a second profiled strip. That too increases the assembly-technical effort and is in need of improvement in terms of handling, especially since the fastening device must be inserted as it were in a revision frame and / or inspection cover.

By the US 4,139,972 a revision device has become known, which has a fastening device by means of which a planking or generally a cladding is determined. The fastening device is adjustably connected to the associated revision frame. For this purpose, the fastening device is composed of interlocking hook elements.

The invention is based on the technical problem of further developing a profiled strip device of the embodiment described at the outset such that the attachment of a planking to, for example, the second profiled strip is simple and problem-free and the assembly is simplified overall.

To solve this technical problem, a generic profile strip device in the invention is characterized in that the fastening head of the second profile strip engages substantially positively and at the same time releasably in the receptacle of the first profile strip. According to an advantageous embodiment of the fastening head is designed resiliently for this purpose. That is, the attachment head can elastically change its shape.

For this purpose, the mounting head is composed according to an advantageous embodiment of two or more spaced apart head legs. The two head legs may be arranged with a central gap to each other and in each case taken together form the cross section of the fastening head.

According to the invention, therefore, a special mounting head is used, which is elastically resilient or can change its shape and this Purpose regularly does not have a closed shape, but rather is designed open. Of course, a closed, for example, spherical, shape of the mounting head can be realized in the context of the invention, as long as it is ensured that the fastening head in question is designed resiliently.

In general, this elastic suspension is realized in the context of a spatially open design of the mounting head, namely by the two or more spaced apart head legs and / or in that the fastening head is made hollow. The head legs can therefore change their distance and / or angle to each other elastically resilient, which is why the described by the two head legs cross-section of the mounting head changes overall elastic yielding its shape.

In this way, it is possible that the mounting head dips into the receptacle on the first profile strip on the second profile strip, wherein the receptacle only at least partially surrounds the fastening head when it is elastically yielding to a certain extent and / or its former Shape changed. Due to the inherent spring forces of the mounting head this endeavors to return to its original shape. As a result, the mounting head is jammed or wedged in the receptacle and ensures that the second profile strip is fixed to the first profile strip, in a certain position of the two strips to each other.

The union between the first and the second profile strip may in the simplest case be done so that the fastening head is clipped into the receptacle. Due to the elastic spring properties of the mounting head, it is of course also possible to remove this again from the receptacle and consequently to dissolve the established connection between the first and second profile strip again and / or to change the position of the strips relative to each other. That is, there is a temporary connection between the first and the second profile strip, wherein the fastening head is in the upright position. would take substantially form-fitting and releasably absorbed. For this purpose, the attachment head is regularly, but not necessarily elastically resilient.

It has proven useful if the two heads defining the fastening head are connected to a common base. In this common base is the second profile strip itself or a leg of the second profile strip, which can not be limited to a planking, a plate, or other facilities can be attached.

The two head legs of the mounting head are designed differently in the rule. In fact, it is in the one head leg to a hook leg, while the other head leg is designed as a locking leg. With the hook leg, the second profile strip is able to engage behind, for example, a projection in or on the recording of the first profile strip in its installed position. Of course, this engaging behind can be done alternatively or additionally by the locking leg. If both head legs engage behind an associated projection in the receptacle of the first profile strip, the receptacle is equipped with respective projections which frame an insertion opening of the receptacle. Through this insertion opening of the mounting head is inserted into the receptacle and thereby elastically yielding compressed. After passing through the insertion opening, the fastening head can then resiliently expand in the receptacle back to its original dimension and is automatically fixed in the receptacle by this process. As a result, the second profile strip learns the desired definition of the first profile strip.

In general, the hook leg and the latching leg are arranged end-to-end on the base and at an angle to each other and to the base. For example, it has been proven that the locking leg and the hook legs are connected at about 90 ° to the base. For this purpose, the base end may have a V-bar, which in turn with its respective V-leg on the one hand, the locking leg and on the other hand, the hook leg wearing. In this case, the respective V-leg is connected with his foot to the base, while the head carries either the locking leg or the hook leg.

In addition, it has proven useful if the mounting head is equipped with at least one guide arc. This guide sheet slides in taking the installation position of the second profile strip relative to the first profile strip generally along the edge of the receptacle or a projection realized at this point along. As a result of this process, the fastening head is compressed from the cross-section or changed in its design so that it can pass through the insertion opening of the receptacle and dive into it. As soon as the fastening head is in the receptacle, the guide arch is no longer located on the edge of the receptacle or a projection there, so that any forces compressing the fastening head fall away and the latter resiliently returns to its original shape and is tilted in the receptacle or is jammed in this.

The receptacle is defined by at least two receiving legs, to which the attachment head or the locking leg and the hook taps! in the installation position. Because the mounting head is composed of the two head legs, it is able to perform elastic changes in certain areas cross-sectional changes. All the more so, as the two profile strips are usually designed as continuous or juxtaposed metal profile strips made of, for example, aluminum or steel. Accordingly, both profile strips and in particular the fastening head of the second profile strip have the required formula elasticity. As a result, not only can the fastening head be fixed in a form-fitting and releasable manner in the receptacle, but also any manufacturing tolerances of the fastening head or the receptacle are accommodated and compensated.

The attachment head is regularly a fastening head profiling, which follows the longitudinal extent of the associated profile strip. Likewise, the receptacle is designed as extending in the longitudinal extent of the associated profile strip receiving groove.

Moreover, it has proven useful if the first profile strip is equipped with a plurality of receptacles arranged along its one leg. In this way, the second profile strip, which can be clamped with the first profile strip, can be fixed in different (height) positions on the said leg and thus on the first profile strip. As a result, for example, a planking, a panel, etc., are fixed to the second profile strip, with depending on the selected recording variable (height) position in comparison to the first profile strip.

The subject matter of the invention is also a revision device which is equipped with a revision frame and an inspection cover insertable in the revision frame. Both the inspection frame and the inspection cover can be equipped with a frame profile for receiving a planking. This frame profile of either the inspection frame or the inspection cover or both can now be prepared according to the invention of a profiled strip device, as described in the introduction. According to an advantageous embodiment, in this context, the first profile strip is designed as a frame profile of the inspection frame and / or the inspection cover and the second profile strip as a fastening device for fixing the mentioned planking.

As already stated above, the second profile strip can be introduced with its mounting head in an installed position in the receptacle and can then be pivoted into a working position. During this pivoting into the working position, the second profile strip is simultaneously fixed relative to the first profile strip. This happens through the interaction of the head and the attachment.

According to the invention, the second profiled strip thus experiences, at least in its working position, a fixation with respect to the first profiled strip, to be precise automatically when changing from the installation position to the working position. Because the second profile strip in this working position is arranged regularly perpendicular to the first profile strip or a leg carrying the receptacle and experiences the described fixation in the working position, a planking or a cladding or the like on the second profile strip can be determined easily. This also succeeds retrospectively, for example, in the event that a revision cover has been produced with the help of the profile strip device according to the invention and the planking should be installed only to complete all installation work.

In this way, the planking of the inspection cover in the example described is not damaged during the entire installation work on a regular ceiling or a raised floor or on or behind a wall paneling. In most cases, such installation work requires that the inspection cover is removed from the inspection frame. The result is that the inspection cover is often parked on the construction site "somewhere" and can be damaged accordingly or worse, even completely lost.

Such problems no longer appear according to the invention, because the planking is installed in the inspection cover only when the described work is completed. In this respect, the invention additionally allows an increased flexibility in comparison with the prior art, because, for example, the color of the planking has to be fixed shortly before installation, and any size or design changes can possibly be made shortly before the end of the work. The same applies of course in the event that the planking on the revision framework - as described - is determined.

In general, the automatic fixing of the fastening head in the receptacle takes place in such a way that the fastening head is clamped during pivoting from the installation position into the working position in the receptacle of the first profiled strip. In order to achieve this deadlock in detail, the fastening head of the second profile strip and the surrounding him receiving the first profile strip in cross section and in combination either alternately round / eccentric or both eccentric. In other words, the fastening head may have a cross-sectionally round shape and is held in an eccentric receptacle. It is equally conceivable that the mounting head has an eccentric cross section and engages in a round recording.

In general and according to a preferred embodiment, however, both the mounting head and the receptacle are each formed eccentrically in cross section. The attachment head is regularly composed of two head legs with a central gap. The two head legs together form the cross section of the mounting head, which is designed circular or eccentric.

In the case of the eccentric design of the mounting head this usually has at least one bulge, which protrudes with respect to a (imaginary) cross-sectional circular area. In general, two bulges are realized on the mounting head, which are preferably substantially diametrically opposite, as compared to a center opposite. The center coincides with the center of the (imaginary) cross-sectional circular area.

The holder is equipped with two holding legs, which enclose a circular to eccentric opening between them. In addition, the two receiving legs define an insertion gap for the mounting head. In general, the insertion gap covers a certain arc angle range. This may be located between 40 ° and 120 °. Preferably, the arc angle range is 60 ° to 100 ° and more preferably a range between 70 ° and 90 °.

Characterized in that the recording of two receiving legs is defined and the mounting head is also composed of two head legs, Both the recording and the mounting head are able to perform elastic changes in cross-sectional changes in certain areas. All the more so, as the two profile strips are usually designed as a metal profile strips, for example, aluminum or steel. Due to this dimensional elasticity of both the mounting head and the recording, it is possible without problems to jam the mounting head when changing from the mounting position to the working position in the recording and the mounting head can easily be released when pivoting back from the working position to the mounting position. In addition, this formula ensures elasticity of the mounting head as the recording that any manufacturing tolerances of the mounting head respectively the recording can be added and compensated.

The attachment head is usually a profiled attachment head which follows the longitudinal extent of the associated profiled strip. Likewise, the receptacle is designed as extending in the longitudinal extent of the associated profile strip receiving groove. As a result, it is necessary that the second profiled strip with its fastening head or fastening head profile is inserted into the receptacle or receiving groove of the first profiled strip or has to be inserted. That is, the installation position ultimately represents an insertion position or insertion position. Accordingly, the working position corresponds to a clamping position.

Both the insertion position and the clamping position correspond to a particular angle that the second profile strip occupies or occupy with respect to the first profile strip. The cultivation of the second profile strip thus imperatively requires compliance with the insertion angle associated with the insertion angle. Likewise belongs to the clamping position a certain clamping angle, which specifies the working position.

The already mentioned insertion gap of the receptacle is opened asymmetrically in comparison to an axis of symmetry of the recording. As a result, the invention takes into account the fact that the second profile strip of their built-in Position or insertion position is pivoted up to the working position or clamping position almost at right angles. In order to limit the pivoting angle at this point and to define the insertion position or installation position as well as the working position or clamping position, the two profile strips are equipped with the aforementioned pivot angles both the insertion angle or clamping angle limiting attacks.

In addition, it has proven useful if the first profile strip is equipped with a plurality of receptacles arranged along the already mentioned leg. In this way, the second profile strip, which can be clamped with the first profile strip, can be fixed in different (height) positions on the said leg and thus on the first profile strip. As a result, for example, a planking, a cladding, etc. can be fixed to the second profile strip, with depending on the selected recording variable (height) position in comparison to the first profile strip.

Finally, the second profile strip can also assume a mounting position. The mounting position occurs as a third position of the second profiled strip relative to the first profiled strip to the installation position and the working position and is different from the two positions. In most cases, the working position corresponds to the fact that the second profile strip is arranged at right angles or nearly at right angles to the leg with the receptacles arranged therein. In the mounting position, however, the second profile strip extends predominantly in the direction of the said leg. The installation position is now located between the mounting position and working position.

Even in the mounting position, the second profile strip is usually fixed relative to the first profile strip. As a result, can be reliably excluded during assembly that the second profile strip may be lost during this process. This is particularly important when attaching the profile strip on a more or less vertical wall of importance. In any case, the additional mounting position ensures that the second profile strip initially saves space on the first profile strip in the course of installation is created and at the same time undergoes a fixation. If then the profile strip device is completely ready to install, the second profile strip can be easily converted into their installed position. For this purpose, the second profile strip undergoes a pivoting operation by about 90 ° in the transition from the mounting position to the working position.

The invention also provides an inspection device which is equipped with a revision frame and an inspection cover which can be inserted into the inspection frame. Both the inspection frame and the inspection cover can be equipped with a frame profile for receiving a planking. This frame profile of either the inspection frame or the inspection cover or both can now be made according to the invention of a profiled strip device, as described above.

In the following the invention will be explained in more detail with reference to a drawing showing only one exemplary embodiment. Show it:

11 to 14 different variants of the fastening device according to Fig. 10 and their attachment to the frame profile.

1 to 5 and 7, 8 and 11 to 14 a profile strip device is shown, which is composed of a first profile strip 1 and a second profile strip 2. With the help of the profiled strip device or the two profiled strips 1, 2 it is advantageously possible to produce frame profiled strip devices, ie, openings in frames, for example, walls, ceilings or floors, which are produced from the two profiled strips 1, 2 to be described in detail below , In the context of the embodiment, the profiled strip device from the two profiled strips 1, 2 is used inter alia for the production of a revision device, as shown in FIGS. 6, 9 and 10. In this case, the profiled strip device of the two profiled strips 1, 2 thus serves to define the frame of the relevant inspection device.

It can be seen that the second profiled strip 2 can be connected to the first profiled strip 1, namely detachably. For this purpose, the second profile strip 2 has at least one fastening head 3, which is received in at least one receptacle 4 on the first profile strip 1 or engages in said receptacle 4. Within the scope of the exemplary embodiment, the first profiled strip 1 is equipped with several receptacles 4 (actually up to four receptacles 4 are realized). Here are the individual receptacles 4 in the first profile strip 1 each along a leg 1a of this first profile strip. 1 At these the receptacles 4 in the example having leg 1a another leg 1 b of the first profile strip 1 is connected. Both legs 1a, 1b of the first profiled strip 1 are substantially perpendicular to each other, so that the profiled strip 1 is designed in cross section largely L-shaped, which of course does not necessarily have to be realized. The leg 1b of the profile strip 1 may serve to accommodate a planking, cladding, etc., or serves as a support therefor. In the embodiment according to FIGS. 6, 9 and 10, however, said leg 1b functions as a limit stop in an opening.

The same applies to the second profile strip 2, which is also and regularly used as a support for a panel or a planking 5, as shown in FIGS. 6, 9 and 10 represent. In this context, the three or more generally the several along the leg 1a in the realization of a revision device superposed receptacles 4 sure that the mentioned planking 5 can be adjusted in height adjustable by means of the second profile strip 2 to the first profile strip 1.

Thus, the panel 5 in question, for example, even later on the said leg or the second profile strip 2 can be set, and without problems, the invention provides that the second profile strip 2 is inserted with its mounting head 3 in the installed position in the associated receptacle 4 and then pivoted into a working position and this is simultaneously fixed relative to the first profile strip 1. The installation position of the second profiled strip 2 corresponds to the lower layer shown in FIGS. 1 and 7. In contrast, the position shown above the second profile strip 2 belongs to their working position. Since the profiled strips 1, 2 in the exemplary embodiment are designed as metal profile strips made of aluminum or steel and each extend over a certain length, the fastening head 3 is in strictestitude about a fastening head profile 3, whereas the receptacle 4 is designed as a receiving groove 4. For this reason, the fastening head or the fastening profile 3 must fit into the receptacle or mounting be inserted 4 in the installation position. This corresponds to the insertion position.

Since the second profile strip 2 is clamped with its mounting head 3 during pivoting from the installation position into the working position in the receptacle 4 of the first profiled strip 1, the working position is also referred to below as a clamping position (in comparison to the insertion position). Both the insertion position and the clamping position correspond to a specific angle α between the second profiled strip 2 and the leg 1a of the first profile strip 1 having the receptacle (s) 4. This includes an insertion angle αi of approximately 10 ° and a clamping angle 0: 2 of about 90 °. Consequently, the second profiled strip 2 when changing from the insertion position to the clamping position almost at right angles (by about 80 °) to be pivoted (see Fig. 1).

It can be seen from the enlarged illustrations in FIGS. 2 and 3 that both the fastening head 3 and the receptacle 4 are formed eccentrically in cross-section. For this purpose, the mounting head 3 has two bulges 6, which are diametrically opposed to a center 7 of a cross-sectional circular area 18. The Querschnittsfläch- surface 18 is indicated by dashed lines and corresponds to an (imaginary) circular cross-section of the mounting head 3. This differs from the mounting head 3, because at this point the already mentioned bulges 6 are realized, which is substantially diametrically compared to the center 7 are opposite. In this case, a bulge 6 is formed on a head and the other bulge 6 at one foot of two head legs 3a, 3b, of which the fastening head 3 is composed. Between the two head legs 3a, 3b, a central gap 3c is provided.

As a result of the fact that the fastening head 3 has the two head legs 3 a, 3 b or they define the fastening head 3, the fastening head 3 is designed to be elastic with respect to its shape. The same applies to the receptacle 4, which is equipped with two receiving legs 4a, 4b. The two Receiving legs 4a, 4b include a substantially circular or eccentric opening 4c between them. In this circular opening 4c of the mounting head 3 is received. In addition, the two receiving legs 4a, 4b define an insertion gap 4d for the fastening head 3. It can be seen that the insertion gap 4d sweeps over a bend angle β in the range between approximately 40 ° and 120 °, in the exemplary embodiment between 70 ° and 90 °. The arc angle β is composed of two partial angles β-i and β ₂ (see Fig. 2).

Here, in the installed position of the leg 1a upper partial angle ß2 is greater compared to the underlying partial angle ß- |. As a result, the insertion gap 4d of the receptacle 4 is opened asymmetrically compared to an axis of symmetry X of the receptacle 4. This fact takes into account the fact that in the clamping position of the legs 1 b of the first profile 1 and the second profile 2 are arranged parallel to each other or should be, as Fig. 1 makes clear. Additional stops 2 ¹ ensure at this point that the pivoting of the second profile strip 2 with respect to the first profile strip 1 to the already mentioned almost 90 ° (more precisely: about 80 °) is limited.

Because both the mounting head 3 and the receptacle enclosing it 4 of each leg 3a, 3b; 4a, 4b are constructed and the rest of the respective profile strip 1, 2 is made of metal, both the mounting head 3 and the receptacle 4 can change elastically with respect to their shape. This makes it possible that not only the mounting head 3 is fixed in the receptacle 4 in the working position or clamping position due to the bulges 6, but that this fixation when changing from the clamping position into the insertion position can also be canceled. That is, the two profile strips 1, 2 are detachably connected to each other and can be reproducibly transferred to the insertion position and the clamping position. It should be additionally considered that the receptacle 4 is equipped with a bulge 10, the opposite of the insertion 4d finds an arrangement and ultimately provides for the eccentric nature of the opening 4c.

This makes it easy to insert the second profiled strip 2 in the insertion position, because in this case the one bulge 6 on the head leg 3b more or less engages in the bulge 10 of the receptacle 4. By contrast, the second bulge 6 of the fastening head 3 is arranged in the insertion gap 4d and does not engage in the receptacle 4. Now, if the second profile strip 2 is transferred from its installation position or insertion position in the working position or clamping position, the bulge 6 leaves the head leg 3b, the recess or bulge 10 in the receptacle 4. At the same time dives the second bulge 6 of the mounting head 3 on the head leg 3a in the recording 4 increasingly. As a result, the two bulges 6 of the mounting head 3 now ensure that the second profile strip 2 is clamped with its mounting head 3 in the receptacle 4 of the first profile strip 1.

A similar procedure and function is observed for the modified embodiment of FIGS. 4 and 5. Here, in addition to the mounting position of the second profiled strip 2 in a substantially vertical arrangement compared to the leg 1a, a mounting position is added, which corresponds to the position of the second profiled strip 2 substantially rectified to the leg 1a. Between the working position and the described mounting position, the insertion position or installation position is now arranged. In this case, the second profile strip 2 is fixed both in the working position and in the mounting position each clamping with its mounting head 3 in the respective recording 4. To achieve this, the mounting head 3 in the embodiment according to FIGS. 4 and 5 has a total of four bulges 6, which are diametrically opposed in pairs diametrically in pairs in comparison to the center 7 in pairs. The four bulges 6 are respectively formed at the head and at the foot of the two head legs 3a, 3b. In this way, the bulges 6 in the (middle) installation position of FIG. 4 unfold in the associated receptacle 4 only on the head side of the two head legs 3a, 3b. In contrast, the two bulges 6 at the foot of the two head legs 3a, 3b free. If, on the other hand, the second profiled strip 2 assumes the mounting position shown in the lower part of FIG. 4 with respect to the first profiled strip 1, then the bulge 6 which additionally plunges into the receptacle 4 on the head leg 3b provides the required clamping action. The same applies to the working position shown in the upper part of Fig. 4, in which the bulge 6 at the foot of the head leg 3a ensures the required clamping action.

It can be seen that the second profile strip 2 is pivoted at the transition from the mounting position to the working position by almost 90 °. In contrast, the second profile strip is in the installed position or insertion position in an intermediate position between the working position and the mounting position.

The exemplary use of the profile strip device according to FIGS. 1 to 5 in the realization of a revision device will now be shown with reference to FIG. This revision device is equipped with a revision frame 11 and an insertable into the inspection frame 11 inspection cover 12. Both the inspection frame 11 and the inspection cover 12 are each equipped with a frame profile 13 respectively 14 for receiving the planking 5. In the exemplary embodiment, the frame profile 13 of the inspection frame 11 is constructed from the above-described profiled strip device according to FIGS. 1 to 3 or 4 and 5. In fact, the frame profile 13 is composed of the first profile strip 1 and the second profile strip 2.

Because the second profiled strip 2 can be connected vertically variable to the first profiled strip 1 and thus the frame profile 13 of the inspection frame 11, planks 5 of different thickness S can be fixed to the second profiled strip 2 or a fastening device realized in this way. In FIGS. 7 and 8, a profile strip device is shown, which is composed again of a first profile strip 1 and a second profile strip 2. With the help of the profiled strip device or the two profiled strips 1, 2 can in turn and advantageous Zargen-Profilleistenvorrichtungen produce, so openings in, for example, walls, ceilings or floors lining frame. The frame profile strip devices or frames are defined from the two profiled strips 1, 2, which will be described below in detail. In the context of the exemplary embodiment, the profiled strip device of the two profiled strips 1, 2 is used inter alia for producing a revision device, as shown in FIG. 9. In this case, the profiled strip device according to FIGS. 7 and 8 from the two profiled strips 1, 2 thus serves to define the frame of the relevant inspection device. Not shown is the further possibility to produce the cover of the inspection device by means of the profile strips 1, 2.

In particular, with reference to FIG. 7 it can be seen that the second profiled strip 2 can be connected to the first profiled strip 1, specifically in a form-fitting and releasable manner. For this purpose, the second profiled strip 2 has the at least one fastening head 3 which is received in a form-fitting and releasable manner in at least one receptacle 4 on the first profiled strip 1 or which engages in said receptacle 4. Within the scope of the exemplary embodiment, the first profiled strip 1 is equipped with a plurality of receptacles 4 (actually four receptacles 4 are realized in FIG. 7). Here are the individual receptacles 4 in the first profile strip 1 along the leg 1 a of the first profile strip. 1

At this the four receptacles 4 in the example having leg 1a, the other leg 1 b of the first profile strip 1 is connected. Both legs 1a, 1b of the first profiled strip 1 are substantially at right angles to one another, so that the first profiled strip 1 is largely L-shaped in cross-section. Of course this is not mandatory. The leg 1b of the profile strip 1 may serve as usual to accommodate a planking, trim, etc., or serves as a support for this purpose. In the embodiment of the Fig. 9, said leg 1 b acts as a limit stop in an opening, for a revision cover 12 with frame profile 14th

The same applies to the second profiled strip 2, which is also and regularly used as a support for a cladding or a planking 5, as shown in FIG. 9. In this context, the four along the leg 1a in the realization of a revision device of FIG. 9 superimposed receptacles 4 ensure that the planking 5 in question can be adjusted in height adjustable by means of the second profile strip 2 to the first profile strip 1.

So that the relevant paneling 5 can also be subsequently fixed, for example, to the said leg or the second profile strip 2, namely without problems, it is provided according to the invention that the second profile strip 2 with its fastening head 3 is essentially positive and releasable in its installed position engages the receptacle 4. In this case, the mounting head 3 is elastically resilient and is composed for this purpose in the embodiment of the two spaced-apart head legs 3a, 3b together. A central gap 3c may be provided between the two head legs 3a, 3b (see Fig. 8).

Due to the fact that the fastening head 3 has the two head legs 3a, 3b and / or these define the fastening head 3, the fastening head 3 is resiliently yielding with regard to its shape. For this purpose, the two head legs 3a, 3b are connected to a common base or a leg 2a of the second profiled strip 2. The leg 2a of the second profiled strip 2 serves to fix the planking 5 (see Fig. 9).

It can be seen that the two head legs 3a, 3b protrude at an angle from the base or the leg 2a, for example, in each case at right angles to the base or the leg 2a. As a result, the two head Donate! 3a, 3b arranged opposite each other and have between them an angle of about 180 °.

The two head legs 3a, 3b of the mounting head 3 are designed differently, as can be seen in particular in the enlarged view of FIG. In fact, one head leg 3a is designed as a hook leg 3a and the other head leg 3b as a locking leg 3b. In the exemplary embodiment, both the hook leg 3 a and the latching leg 3 b engage behind a respective projection 16 in the receptacle 4 of the first profile strip, in the installation position shown in FIG. 7.

The receptacle 4 is composed again of the two receiving legs 4a, 4b and an opening 4c, which acts as a receiving base 4c. For the maintenance of the mounting head 3 in the receptacle 4 primarily provide the two receiving legs 4a, 4b in conjunction with the two opposing projections 16. Actually define the two projections 16 an insertion or the insertion 4d and 17 respectively for the mounting head.

The insertion opening 17 has a cross-section or a width B. The fastening head 3 has a diameter or a spacing A of the ends of the two opposing limbs 3a, 3b. Thus, the mounting head 3 is securely held in the receptacle 4 and clamped, is that the distance B of the projections 16 is smaller than the distance A of the ends of the head legs 3a, 3b configured, ie

A> B

applies.

Since the profiled strip device as a whole or both of its profiled strips 1, 2 are made as continuous metal profiled strips of, for example, aluminum or steel, the two head limbs 3a, 3b can be compressed and consequently their distance A (temporarily and elastically resilient), namely, until the distance A is substantially equal to the distance B of the two projections 16 to one another. This compression or the compression of the mounting head 3 is in the exemplary embodiment performed so that the mounting head 3 with its two head legs 3a, 3b is inserted obliquely into the receptacle 4.

For this purpose, first the hook leg 3a engages behind the lower projection 16 of the receptacle 4. If now starting from this dashed Dar position in Fig. 7, the second profile strip 2 is pivoted in the arrow direction, provides a guide arc 8 on the mounting head 3 and the end of the locking leg 3b for the necessary compression of the mounting head 3 and a reduction of the distance A. For this purpose, the guide sheet 8 slides on the upper projection 16 of the receptacle 4 when passing through the insertion opening 17 along, so that the two head legs 3a, 3b with slight reduction of their Gap 3c pass between the insertion opening 17. Once both head legs 3a, 3b have passed the two projections 16, they are able to spring back to their original size. In this case, both the hook leg 3a and the latching leg 3b engage behind the associated projections 16 on both sides of the receptacle 4. The described procedure is of course only to be understood as an example since the mounting head 3 can also be pressed into the receptacle 4 frontally and clipped into it.

It can be seen that the two head legs 3a, 3b arranged substantially at right angles to the leg 2a or the base 2a are connected to a V-web 9. This V-web 9 defines with its two V-legs 9a, 9b, the gap 3c between the two head legs 3a, 3b, which is also designed V-shaped. The two head legs 3a, 3b are respectively connected on the head side to the associated V-legs 9a, 9b. The V-legs 9a, 9b are in turn connected to the base or leg 2a of the second profiled strip 2 on the foot side. As already stated in the introduction, the two profiled strips 1, 2 are continuous metal profiled strips. The receptacles 4 each form receiving grooves 4. To connect the second profiled strip 2 with the first profiled strip 1, it is therefore only necessary to insert the fastening head 3 into the receptacle 4 in a clip-on manner. In this case, this process can be supported by an additional pivoting movement of the second profile strip 2 as shown in Fig. 7, but this is not mandatory.

With reference to FIG. 9, the exemplary use of the profile strip device according to FIGS. 7 and 8 in the realization of a revision device becomes clear. The revision device is equipped with the revision frame 11 and the inspection cover 11 which can be used in the revision frame 11. Both the inspection frame 11 and the inspection cover 12 are each equipped with the frame profile 13 respectively 14 for receiving the planking 5. In the exemplary embodiment, the frame profile 13 of the inspection frame 11 is constructed from the above-described profiled strip device according to FIGS. 7 and 8. In fact, the frame profile 13 is composed of the first profile strip 1 and the second profile strip 2 as described.

Because the second profiled strip 2 can be connected vertically variable to the first profiled strip 1 and thus the frame profile 13 of the inspection frame 11, planks 5 of different thickness S can be fixed to the second profiled strip 2 or a fastening device realized in this way, as in the right-hand part Fig. 9 is shown.

10 to 14, a revision device or a profile strip device is shown, which serves in its basic structure to release an opening 15 in a wall, ceiling and / or floor panel 19, if necessary, to behind the panel 19 in question In order to be able to realize this in detail, the inspection device shown in its basic structure consists of the inspection frame 11 and a frame inside. on the side in this revision frame 11 usable inspection cover 12 together.

The inspection cover 12 is formed in cross-section L-shaped and has the associated frame profile 14. A plurality of legs of the frame profile 14 are circumferentially connected to each other and form the inspection cover 12. In the interior of the inspection cover 12, a cover panel 5 or generally the planking 5 is received, which is enclosed by the peripheral frame profile 14.

The inspection frame 11 also has a peripheral and the opening 15 bordering frame profile 13, which corresponds to the first profile strip 1 and in the same way - as the inspection cover 12 - is designed in cross-section L-shaped. Like the cover profile 14, so the frame profile 13 of the inspection frame 11 is adapted to receive a panel 5, namely the planking 5, which is received in the frame section 13.

It can be seen with reference to FIG. 10 that the frame-side planking 5 can be designed with different planking thicknesses S. In order to compensate for these different planking thicknesses S of the planking 5, a fastening device 2 in the form of the second profiled strip 2 for fixing the planking 5 in question is provided on the frame profile 13 of the inspection frame 11 or the first profiled strip 1. The fastening device 2 is depth adjustable in the embodiment connected to the inspection frame 11. In this way, the position of the fastening device 2 in the frame depth direction T can be varied. In the fastening device 2, it is shown in FIGS. 11 to 14 and not restricting to a bar, which is basically constructed in two parts and has the mounting head 3 and a support leg or legs 2a.

14, 11, 12 and 13, it can be seen that the fastening head 3 is circular in cross-section (see FIG. 14), dovetailed (compare FIGS. 11 and 12) or also U-shaped (cf. Fig. 13) can be trained. Since the fastening device 2 is configured overall as a strip, the front side of the support leg 2a provided mounting head 3 is a corresponding circular, dovetail-like or U-shaped profiling at this point (front).

11 to 14 it can be seen that the fastening device 2 or the second profiled strip 2 with its mounting head 3 positively and at the same time releasably in the at least one receptacle 4 on the frame section 13 of the inspection frame 11 and in the first profile strip. 1 intervenes. In principle, the fastening device 2 can also be connected to the frame profile 14 of the inspection cover 12. However, this is not shown, because usually the revision frame 11 is set up to accommodate different panel thicknesses S.

Depending on the contour and cross-sectional shape of the mounting head 3, the associated receptacle 4 has a corresponding shape in order to ensure the positive retention of the mounting head 3 in the receptacle 4. In fact, the receptacle 4 in the exemplary embodiment is a receiving groove which follows the longitudinal extension of the fastening device 2 designed as a strip or is adapted to it.

In this way, it is ensured on the whole that the fastening device 2 (in its working position) is aligned essentially at right angles to the frame profile 13. In fact, in the exemplary embodiment, the fastening device 2 extends perpendicularly or at right angles to the longer L-leg 1a of the cross-sectionally L-shaped frame profile 13, whereas the shorter L-leg 1b extends parallel to the fastening device 2. Reference numeral 1c designates in FIGS. 10 to 14 a visible edge 1c of the inspection frame 11 with which the planking 5, together with optionally a surface covering, terminates flush with the surface.

As a result of the rectangular arrangement of the fastening device 2 or its support leg 2a in comparison to the frame profile 13 of the revision Frame 11 ensures that the planking 5 rests overall and almost flat on the support leg 2a of the fastening device 2. An additional profiling 2b (see Fig. 14) may at this point ensure that an adhesive applied to the support leg 2a or generally the fastening device 2, after hardening, keeps the planking 5 captive. Additionally or alternatively, the planking 5 can also be connected by means of one or more fastening means 20 with the support leg 2a in question. The fastener 20 may be a screw, a rivet or the like.

In the variant according to FIG. 11, two receptacles 4 are provided in the frame profile 13 of the inspection frame 11 in order to be able to fix the fastening device 2 depending on the planking thickness S of the planking 5 surrounding it. The same applies to the embodiment according to FIG. 14, which at this point even realizes four different receptacles 4 on the frame profile 13 of the inspection frame 11. The multiple receptacles 4 are placed in the frame depth direction T one behind the other and parallel to one another in the longitudinal direction of the frame profile 13.

In this case, there is a recording 4 or find the more shots 4 each in the longer L-leg 1a. The variant according to FIG. 13 also works with two receptacles 4, which here however serve the positive and detachable mounting of the U-shaped fastening head 3 of the fastening device 2 realized at this point.

The exemplary embodiments according to FIGS. 12 to 14 have in common that the fastening device 2 can be fixed in at least two different functional positions on the inspection frame 11 or its frame profile 13. These different functional positions correspond in the examples according to FIGS. 12 and 13 to different panel thicknesses S or take this into account. By contrast, the embodiment according to FIG. 14 uses the various functional positions of the fastening device 2 to mount the inspection frame 11 in the latter To facilitate opening 15 in the panel 19. In this case, the fastening device 2 engages in the cases described in each case in one and the same receptacle 4 a.

In the context of FIGS. 12 and 13, the fastening device 2 can be rotated about an axis Z, namely by 180 °. In this case, the axis Z in question runs perpendicular to the frame profile 13 of the inspection frame 11 or perpendicular to its longer L-leg 1a. Since, in the case of FIGS. 12 and 13, the fastening device 2 is designed overall L-shaped, this rotation about the axis Z results in that the support leg 2 a of the fastening device 2 has a different distance C compared to the visible edge 1 c of the inspection frame 11 to be able to record in the example the two different planking thicknesses S of the planking 5.

In the variant according to FIG. 14, the fastening device 2 can likewise assume two functional positions, again by a rotation about a different axis Z ', in this case in the longitudinal extent of the frame profile 13 or its longer L-leg 1a and also in the longitudinal direction the groove-like receptacle 4 extends. During rotation about this axis 71, the fastening device 2 or its support leg 2a completes a 90 ° rotation. In this way, the fastening device or the second profile strip 2 on the inside of the inspection frame 11 folded (assembly position) and folded from this (working position), as has already been explained with reference to the embodiments of FIGS. 1 to 5. In folded mounting position, the inspection frame 11 can be easily introduced into the opening 15 together with the fastening device 2. Thereafter, the fastening device 2 is folded down into the working position and is now on the planking 5 on.

In this case, the fastening device 2 can be latched after folding or pivoting about the axis Z ¹ by 90 ° in the receptacle 4 to prevent after insertion of the inspection frame 11 in the opening 15 a renewed folding down the fastening device 2 (working position). In any case, the determination of the planking 5 with the different planking thickness S always takes place at the support leg 2a, in which case an adhesive agent applied to the profiling 2b additionally or solely provides the required connection. The adaptation to the different planking of the different planking thicknesses S takes place - as in the variant according to FIG. 11 - in such a way that the fastening device 2 with its fastening head 3 is fixed positively and detachably in the receptacle 4 corresponding to the respective planking thickness S.
