The separation spot can be formed as a detent seat connection (R). All the covers and separating spots can be combined by connectors (6) into one structural unit. The connectors can be in three parts with cover arms (6a) at the end sides and a connecting web (6b) in the middle.

Description

The invention relates to a roller shutter box, with a composite from Blenddeckeln and at least one bottom cover box body, and optionally frontal box covers, with individual covers form a flat and at least partial representation of the box body collapsible unit, further comprising one or more separation points in the respective visor and / or provided in the bottom cover and / or in the box lid, so that the associated cover can be opened and closed again in the region of this separation point, and wherein the cover and the bottom cover are joined together by the respective longitudinal edge connecting means to the aforementioned unit.

Usually, three visor covers are used, namely an outside, an inside and a head-side visor cover, while the bottom cover is used for the bottom end of the box body or the roller shutter box. In or on the bottom cover a slot for the generally located in the box body roller shutter is provided.

In the case of the roller shutter box disclosed in DE 195 22 973 A1, a roller shutter box body is used, which is at least partially composed of an assembly of individual lids. To complete this unit, a lid piece and a bottom piece are required. In this then completed box body a roller shutter armor is inserted.

A roller shutter box according to the preamble of claim 1 is described in the context of DE 43 21 113 A1, which presents a roller shutter prefabricated whose different covers or plates form a single unit and at their longitudinal edges each have a half of a compound with which the box held together becomes. The mating connecting halves are combined to form hinges, which hold the plate together in the unit and serve as connecting joints. This hopes to be able to provide a roller shutter box available, which is composed with a large variety of possible dimensions of a few individual parts.

The prior art is further pointed to the German utility model DE 93 01 459 U1, in which a constant problem is that differently designed visor with the special bottom cover must be assembled to the box body. In addition, cutting to length usually requires separate treatment of the aforementioned lids. - Here the invention aims to provide a total remedy.

The invention is based on the technical problem of further developing such a roller shutter box so that a simple revision and a trouble-free assembly is ensured.

To achieve this object, the invention proposes in a generic roller shutter box, that the connecting means are designed in three parts with end cap legs and central connecting web, wherein the connecting web is made of an elastomer. - The separation points are usually designed as a snap fit connection or even have corresponding connection means.

In this way it is achieved that the cover together with the bottom cover - usually for transport and processing - form a substantially flat and at least partial representation of the box body collapsible unit. In this case, the cover, bottom cover and connecting means can be performed regularly as a jointly manufactured press profiles or extruded profiles in order to enable a fast and rational production.

According to an independent proposal of the invention, the cover, bottom cover and connecting means are designed as coextruded plastic (hollow) profiles, so that the entire box body (including separation points) can be made in situ and in one piece. In this coextrusion must, of course, be taken to ensure that the connecting means have the required elasticity, so that the folding collapses to illustrate the box body easily.

According to an alternative of the invention it is provided that the connecting means are designed as the cover and the bottom cover connecting each separate hinge connector. The same applies to the separation points. These hinge connectors are usually connected after production of the cover and the bottom cover each with these longitudinal edge side and ensure in connection thereto for the desired definition of the unit described. In the same way, the hinge connectors ensure the coupling of individual parts of the respective cover (bottom cover and / or cover) in the region of the separation point.

In general, the connecting means are made in three parts with end cap legs and central connecting web. In this case, the connecting web is usually made of an elastomer or a similar flexible elastic spring material. If an elastomer is used, this generally has a Shore A hardness of about 50 to 90, so that both a flat unfolding of the interconnected lid as a folding to the box body as well as a separation and assembly of the lid easily allows becomes. In this case, a reproducible representation of the box body, for example, by the front side attachable box lid, which provide for the required hold the lid (cover and bottom lid) to each other.

For the end lid shank comes however, usually a thermoset or thermoplastic used. The (separate) connection means can be particularly elegant and easy to produce in case that hard polyvinyl chloride (PVC) is used for the cover legs, while the connecting web is made of soft polyvinyl chloride (PVC). Because in this case, a production of the bonding agent in the context of a single (co-) extrusion process done. Metals are also conceivable as materials for the connecting means.

The cover legs are generally designed as engaging in hollow chambers of the visor cover and the bottom cover latching leg, can thus easily lock with each lid to be connected. Of course, at this point, other compounds, such as adhesive, screw, rivet or even connectors conceivable.

If a locking connection is followed, the locking legs or cover legs can each have two substantially parallel spring arms. These spring arms are an inner and an outer spring arm facing the box interior. Characterized in that the spring arms are separated from each other, they can move towards each other in the course of the detent and set themselves back after production of the locking connection. In particular, preferably at least the respective inner spring arm of the associated locking leg has a latching hook engaging behind a latching lug in the hollow chamber. Of course, this latching hook can in principle also be arranged on the connecting means, for example integrally formed, without the connecting means being equipped with the lid legs or the spring arms.

In order to be able to define different positions of the cover plate and the bottom cover connected to the structural unit, the connecting means are usually fixable in different angular positions (the cover legs relative to one another) as a rule. These angular positions may be, for example, a so-called 0 ° position and a 90 ° position. On the 0 ° position is usually used for the transport or a processing of the unit, while the 90 ° position corresponds to the folded box body.

In order to represent the collapsed state of the roller shutter body properly, at least one lid leg has a stop lug for defining the associated angular position of the connecting means. Finally, the roller shutter box according to the invention, as regards the usable materials, designed extremely flexible. Because fundamentally very different materials can be connected to each other (if used on the separate longitudinal edge-side connecting means). In this context, it is proposed to perform the cover and the bottom cover as metal and / or wood and / or plastic (hollow) profile.

As a result, the shutter box described above initially characterized by a simple machinability, because the unfolded flat state of the assembly of Blenddeckeln and bottom cover a tailor-made and even automated cutting - adapted to the respective tank size or window size - allows. In addition, the transport is facilitated because the belonging to the roller shutter box components are completely connected to each other, so that confusion can be virtually ruled out. At the same time, the unit takes up as little space as possible in the flat state, so that the most expensive transport volume is optimally utilized.

In addition, the construction can be performed as easily as possible, because this only need to be unfolded the cover and the bottom cover. Usually, the connection means inherent angle stop ensures compliance with the desired (right) angle. Of course, in principle hexagonal configurations of the roller shutter box according to the invention are also conceivable in cross section. Finally, the solution described convinces by the possibility of using very different materials, so that a variety of design and material requirements can be accommodated.

The one or more separation points in the respective cover or in the bottom cover ensures that in any case a revision of the entire roller shutter box or the roller shutter located therein succeeds extremely simple and problem-free. Because the actual box body is not changed by its shape, which must be considered, for example, when flush mounting or wall installation. Rather, the then provided for example in the bottom cover separation point just allows a two or more division of this bottom cover so that the roller shutter from the bottom can be removed from the box body. Consequently, this roller shutter can be replaced or provided, for example, with an electric drive, without the roller shutter box must be removed as a whole.

It should be noted that it can be at the separation point to any separable connection, so far as a non-locking seat connection is possible. Thus, it is conceivable to resort to their own connecting means, which are designed similarly, as has already been described for the connection means for coupling of the cover and the bottom cover. Consequently, comparably designed connecting means can be used, which are designed, for example, in three parts with end cap legs and central connecting web. Likewise, the invention recommends the connecting web of these connecting means for coupling individual cover parts in the context of To make separation point of an elastomer or the like. Elastic spring material, so that a perfect separation and reconnection in the region of this separation succeed. Consequently, the lid legs usually engage in hollow chambers of the associated lid and are designed as corresponding latching legs. Here are the main advantages of the invention.

an embodiment of the connecting means in the extended and folded state and

6 and 7

and FIGS. 8 and 9 show other embodiments of the objects according to FIGS. 4 and 5.

In the figures, a roller shutter box is shown, which is composed in its basic structure of three Blenddeckeln 1, a bottom cover 2 and only indicated box covers 3. Blend cover 1 and bottom cover 2 form a box body K, on which the box lid 3 are placed on the front side. The case cover 3 according to the embodiment provide the required stability and compliance with the spatial form of the box body K, which of course also separate connector o. Ä. Can be used at this point.

It can be seen on the basis of FIG. 2 that the cover 1 together with the bottom cover 2 form a substantially flat structural unit which can be folded to form a complete representation of the box body K. This becomes clear in the transition from FIG. 2 to FIG. Within the shutter box, a merely indicated roller shutter armor 4 is provided, which is unwound via a slot 5 from the roller shutter box.

The cover 1 and the bottom cover 2 are joined together by longitudinally-edge connecting means 6 to the aforementioned unit. Blend cover 1 and bottom cover 2 can be made as well as the connecting means 6 as a jointly manufactured extruded profiles. According to the embodiment in FIGS. 1 and 2, the glare lids 1, the bottom cover 2 and the connecting means 6 to coextruded plastic (hollow) profile, ie an integral unit. The other figures 3 to 9, however, each show separate connecting means 6, which connect the visor 1 and the bottom cover 2 and are designed as a hinge connector 6.

It can be seen from FIGS. 3 to 5 that the connecting means or hinge connectors 6 are formed in three parts with end cap legs 6a and central connecting web 6b. According to the embodiment, the cover legs 6a each consist of a hard plastic, such as hard polyvinyl chloride (PVC). In contrast, the connecting web 6b is made of an elastomer or a comparable flexible elastic spring material. If an elastomer is used, preference is given here to soft polyvinyl chloride (PVC) having a Shore A hardness of about 50 to 90. Consequently, the illustrated hinge connector 6 and the connecting means 6 can be produced in a single (co-) extrusion process, in one piece.

To fix the connecting means 6 to the cover plate 1 or the bottom cover 2, the cover legs 6a are formed as engaging in hollow chambers 7 of the cover 1 and the bottom cover 2 locking leg. In detail, two parallel spring arms 8, 9 are realized in each case in these latching limbs or cover legs 6a, which pairs may in each case be formed identically with respect to the associated cover leg 6a, as shown in FIG. At least the respective inner spring arm 8 of the associated latching leg or cover leg 6a has a latching hook 11 engaging behind a latching lug 10 in the hollow chamber 7. According to the embodiment 9 locking hooks 11 'are realized on the outer spring arm, which engage behind an associated locking lug 10'. In addition, a rail S serves to cover the connection area (see Fig. 5). The same is possible by appropriately extending the associated profiles.

Since the two spring arms 8, 9 have between them a gap 12, they can move towards each other in the course of the detent and take after the latching the original (parallel) position again.

1 to 9 it can be seen that the connecting means or hinge connector 6 in different angular positions - the cover legs 6a to each other - are fixable. Usually, angles of 0 ° (cf., Figures 4, 6 and 8) and 90 ° (see Figures 5, 7 and 9) can be represented. Of course, other angular positions than 0 ° or 90 ° are conceivable. This also applies to additional angular positions, for example in the sequence 0 °, 30 °, 45 °, 60 °, 90 ° etc ..

In order to be able to define at least the folded state of the box body K, at least one cover leg 6a has a stop lug 13 for fixing precisely this angular position (90 ° position). of the connecting means 6.

The visor cover 1 and the bottom cover 2 may be constructed of different materials. Conceivable are combinations of metal and / or wood and / or plastic, wherein in each case respective hollow profiles are used.

In addition to the embodiments of the hinge connector or connecting means 6 in FIGS. 4 and 5, other variants are conceivable, which can be seen in the illustrations 6 to 9. Thus, Figs. 6 and 7 show a two-part embodiment of the connecting means 6 with a latching element 10 engaging in a detent element 15. This locking element 15 is connected via a flexible film hinge 15 'to the visor cover 1 or bottom cover 2. The film hinge 15 'consists of a comparable material as the connecting web 6b. Its production coincides with the procedure described. In addition, there is a trap strip 16, which engages behind a latch strip 17 in the folded state of FIGS. 7 and 9.

In the embodiment shown in FIGS. 8 and 9, in turn, a latching element 15 can be seen. This latching element 15 engages in an associated latching receptacle 14. In order to ensure a secure hold of the locking element 15, undercuts 18, 19 of the locking receptacle 14 are provided. Also in this case, again a trap strip 16 is realized, which cooperates with a latch strip 17 in the manner already described for the representation of the folded state of the box body K.

In contrast to the embodiments according to FIGS. 4 and 5, the connecting means or hinge connector 6 illustrated in FIGS. 6 to 9 are - as described - made of several parts, at least two parts. This is appropriate in the event that certain types of mounting - for example, a length compensation on the connecting means 6 - must be used.

In order to facilitate a simple revision of the entire roller shutter box or the roller shutter 4 or individual units located therein, one or more separation points T are provided in the box body K. According to the embodiment in Fig. 1, a separation point T in the bottom cover 2 and a separation point T in the rear panel 1 is shown. Of course, additionally a further separation point T in the bottom cover 2 or in the rear cover 1 can be realized. In the region of this separation point T, the associated bottom cover 2 can be opened and closed again, with the aid of a latching seat connection R there (see the first enlarged detail in FIG. In any case, this makes it possible to subdivide the bottom cover 2 in order, for example, to be able to simply remove the roller shutter armor 4 from the otherwise closed box body K in the event of a repair. Another advantage of this approach is that - in realization of multiple separation points T in the individual lids 1, 2 of the box body K - intermediate pieces can be used without problems, so that the box body K (theoretically) any size - even later - can take.

Instead of the locking seat connection R shown in Fig. 1 in the first enlarged detail in the region of a separation point T in the bottom cover 2 can be used here also on a connecting means 6, as shown in detail in Fig. 4 and at the separation point T in the rear panel cover 1 use finds. In the same way as shown in Fig. 5, then the connecting means 6 engages in individual hollow chambers 7 of the associated shutter cover 1, as the further enlarged detail in Fig. 1 makes clear. In this way, the connecting means 6 are thus not only used for longitudinal connection of individual covers 1, 2, but are also advantageous for the representation of the separation point T.

In this case, the connecting web 6b of an elastomer or a comparable flexible elastic spring material ensures that the associated visor cover 1 can be properly opened in the region of the separation point T by the connecting means 6 is removed at slightly outwardly folded halves of the visor cover 1 from the associated hollow chambers 7 , The same applies, of course, in the event that such a separation point T with connecting means 6 access to the bottom cover 2 - instead of the locking seat connection R - opens.
