Description

The invention relates to a roller shutter box with one Cover plates and at least one bottom cover put together Box body, and possibly with front Box lids, with individual lids being flat and for at least partial representation of the box body form collapsible unit, further comprising one or several separation points in the respective cover and / or in Bottom cover and / or provided in the box cover, so that the associated cover in the area of this separation point can be opened and closed again, and the Anti-glare cover and the bottom cover through the longitudinal edge Connection means to the aforementioned unit are put together.

Three cover plates are usually used, namely one on the outside, one on the inside and one on the head Cover plate, while the bottom of the Box body or the roller shutter box of the bottom cover serves. In or on the bottom cover is a slot for the im Generally roller shutter curtain in the body of the box intended.

In the known from DE 195 22 973 A1 Roller shutter box, a roller shutter box body is used, which is at least partially made up of one unit individual lids is assembled. To complete this unit is a cover piece and a Bottom piece required. In this then completed A roller shutter curtain is inserted into the body of the box.

A roller shutter box according to the preamble of claim 1 is in the context of DE 43 21 113 A1 described, which presents a roller shutter box, the different lids or plates lying on top of each other form a unit and one on each of its longitudinal edges Have half a connection with which the box is held together. The two belong together Connecting halves united to hinges, which the Hold the plate together in the unit and as connecting joints serve. This is hoped for a roller shutter box to be able to provide, which at large Variety of possible dimensions from a few individual parts is composed.

The state of the art is also on the German Registered utility model DE 93 01 459 U1, in which a constant problem is that different designed cover with the special bottom cover must be assembled to the box body. Moreover cutting requires the usually separate treatment of the aforementioned lid. - Here the invention as a whole Remedy.

The invention is based on the technical problem to form such roller shutter box so that a easy revision and easy assembly is guaranteed.

To achieve this object, the invention proposes generic roller shutter box that the connecting means three parts with end flap legs and middle connecting web are executed, the connecting web made of an elastomer or the same flexible spring material is made. - The separation points are mostly used as a resting seat connection trained or even have corresponding ones Lanyard.

In this way it is achieved that the cover plate together with the bottom cover - usually for transport and for processing - an essentially flat and for at least partial representation of the box body form collapsible unit. You can Cover, bottom cover and lanyard regularly as jointly manufactured press profiles or extruded profiles run to a quick and to enable rational manufacturing.

According to an independent proposal of the invention Cover plate, bottom cover and lanyard as co-extruded plastic (hollow) profiles formed so that the entire box body (including separation points) as it were can be made in situ and from one piece. at this coextrusion must of course take care that the lanyard has the required elasticity have so that the collapse to represent the Box body succeeds easily.

According to an alternative of the invention it is provided that the connecting means as the cover plate and the bottom cover each connecting separate hinge connector are executed. The same applies to the separation points. These hinge connectors are usually made after Manufacture of the cover and the bottom cover each connected to these along the longitudinal edge and ensure in Connection to the desired definition of the described unit. They care in the same way Hinge connector for coupling individual parts of the respective cover (bottom cover and / or cover plate) in Area of the separation point.

In general, the connecting means are in three parts end cover legs and central connecting web executed. The connecting bridge is usually off an elastomer or a similar flexible elastic Made of spring material. If an elastomer is used comes, this generally has a Shore A hardness of approx. 50 to 90 so that both fold out flat the interconnected lid like a Folding up to the box body as well as separating and Merging the lid is easily possible. there succeeds in a reproducible representation of the box body for example, by the plug-on at the front Box lid, which is necessary for the hold of the lid (Cover plate and bottom cover) to each other.

On the other hand, comes for the end cover legs Usually a thermoset or thermoplastic is used. The (separate) connection means can be used for the case particularly elegant and easy to manufacture that hard Polyvinyl chloride (PVC) used for the lid legs is made of soft, while the connecting web Polyvinyl chloride (PVC) is made. Because in this case can manufacture the connecting means in the context of a only (co-) extrusion process. Metals too are conceivable as materials for the connecting means.

The lid legs are generally considered to be in hollow chambers the cover plate or the base cover engaging Locking legs formed, can therefore be easily lock with the respective lids to be connected. Of course there are others here too Connections, for example adhesive, screw, rivet or even plug connections conceivable.

If a rest connection is followed, the Lock leg or lid leg two each Have essentially parallel spring arms. With these The spring arms are inside the box facing inner and one outer spring arm. Thereby, that the spring arms are separated from each other let them move towards each other and stand in the course of the rest back after the locking connection has been made. Specifically, at least each preferably has inner spring arm of the associated locking leg one behind a locking lug in the hollow chamber engaging locking hook. Of course, this locking hook can also in principle arranged on the connecting means, for example molded, without the connecting means with the Lid legs or the spring arms is equipped.

To different positions of the to each other Assembly connected cover plate and the bottom cover To be able to define the connecting means in the Rule optionally in different angular positions (the Cover leg to each other) fixable. At these angular positions can be, for example, a so-called Act a 0 ° position and a 90 ° position. On the 0 ° position is usually used for transportation or too an editing of the unit is used while the 90 ° position to the folded box body corresponds.

To the folded state of the shutter body To be able to display properly, at least one Cover leg a stop lug to define the associated angular position of the connecting means. Finally is the roller shutter box according to the invention, what the applicable materials, extremely flexible designed. Because it can basically be entirely combine different materials (if on the separate connecting means that can be used along the longitudinal edge is used). In this context suggested the cover plate and the bottom cover as Metal and / or wood and / or plastic (hollow) profiles perform.

The result is the roller shutter box described first of all by a simple editability, because the opened flat state of the unit Anti-glare covers and bottom covers are a perfect fit and even automated cutting - adapted to the respective Tank size or window size - allows. Furthermore the transport is facilitated in that the Components belonging to the roller shutter box completely with each other are connected so that confusion is practically impossible can be. At the same time, the Unit in the flat state as little space as possible a so that expensive transport volume is optimally used becomes.

In addition, the construction is child's play can be because of this the cover and the Bottom cover only need to be opened. Usually, the inherent in the lanyards provides Angle stop for compliance with the desired (right) Angle. Of course, in principle Cross-section hexagonal designs of the invention Roller shutter box conceivable. After all, it convinces described solution through the possibility of use completely different materials, so that very different Design and material requirements are taken into account can.

Through the one or more separation points in the respective Cover plate or in the bottom cover ensures that in a revision of the entire roller shutter box or of the roller shutter curtain located here is extremely simple and succeed without any problems. Because the actual box body its shape does not change what for example for flush mounting or wall installation must be observed. Rather, it then allows For example, the separation point provided in the bottom cover a two or more division of this bottom cover, so that the Roller shutter curtain removed from the floor of the box body can be. As a result, this roller shutter curtain exchanged or for example with an electric Drive can be provided without the roller shutter box in the Whole needs to be expanded.

It should be noted that the separation point is any detachable connection can act, that is a non-click seat connection is also possible. That's the way it is conceivable to fall back on their own connection means that are designed similarly to the connection means for coupling the cover plate and base cover already has been described. Consequently, similarly designed ones Lanyards are used, for example three-part with end flap legs and central Connection bridge are executed. The also recommends Invention, the connecting web of these connecting means for Coupling of individual cover parts in the frame of the separation point made of an elastomer or the like To produce spring material, so that a perfect separation and reconnection succeeds in the area of this separation point. As a result, the lid legs usually engage Hollow chambers of the associated lid and are as corresponding locking leg formed. Here are the see essential advantages of the invention.

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

A roller shutter box is shown in the figures its basic structure of three blind covers 1, a bottom cover 2 and only indicated box covers 3 is composed. Cover 1 and base cover 2 form a box body K, on which the Box covers 3 are placed on the front. Care the box cover 3 according to the embodiment for the required stability and compliance with the spatial shape of the Box body K, of course at this point separate connectors or the like can also be used.

2 that the diaphragm cover 1 together with the bottom cover 2 an essentially flat and for the complete representation of the box body K form collapsible unit. This is when Transition from Fig. 2 to Fig. 1 clearly. Within the Roller shutter box is a merely indicated roller shutter curtain 4 provided, which via a slot 5 from the Roller shutter box is unwound.

The cover 1 and the bottom cover 2 are each through longitudinal edge-side connecting means 6 to the aforementioned Unit assembled. Cover cover 1 and base cover 2 can as well as the connecting means 6 as common manufactured extruded profiles. After this Embodiment in Figs. 1 and 2 is the cover 1, the bottom cover 2 and the connecting means 6 um co-extruded plastic (hollow) profiles, so a one-piece unit. The remaining figures 3 to 9 however, each show separate connecting means 6, which connect the cover 1 and the bottom cover 2 and as Hinge connector 6 are executed.

3 to 5 that the Lanyard or hinge connector 6 with three parts end cover legs 6a and central connecting web 6b are formed. According to the embodiment the cover legs 6a each made of a hard plastic, for example hard polyvinyl chloride (PVC). In contrast, is the connecting web 6b made of an elastomer or comparable elastic spring material. If an elastomer is used, preference is given here on soft polyvinyl chloride (PVC) with a Shore A hardness from about 50 to 90. Consequently, the shown hinge connector 6 or the connecting means 6 in a single (co-) extrusion process, and in one piece.

To fix the connecting means 6 on the cover plates 1 or the bottom cover 2 are the cover legs 6a as in Hollow chambers 7 of the cover 1 or the bottom cover 2 engaging locking leg formed. In detail are in these locking legs or cover legs 6a each in Realized two parallel spring arms 8, 9, the pairs in each case the same with reference to the associated Cover leg 6a can be formed, as shown in Fig. 4 is shown. At least the inner spring arm 8 of the associated locking leg or cover leg 6a one behind a locking lug 10 in the hollow chamber 7 engaging locking hook 11. According to the embodiment are also on the outer spring arm 9 locking hooks 11 ' realized that behind an associated latch 10 ' to grab. In addition, a rail S serves to cover the Connection area (see. Fig. 5). The same is through appropriate extension of the associated profiles possible.

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

1 to 9 that the connecting means or hinge connector 6 in different Angular positions - the cover leg 6a to each other - are fixable. Angles of 0 ° are usually possible (see FIGS. 4, 6 and 8) and 90 ° (see FIGS. 5, 7 and 9) represent. Of course, other angular positions are also conceivable as 0 ° or 90 °. This also applies to additional angular positions, for example in the sequence 0 °, 30 °, 45 °, 60 °, 90 ° etc.

To at least the folded state of the Being able to define box body K has at least one Cover leg 6a a stop lug 13 for fixing flat this angular position (90 ° position) of the connecting means 6 on.

The cover 1 and the bottom cover 2 can different materials. Are conceivable Combinations of metal and / or wood and / or plastic, in general, respective hollow profiles are used come.

In addition to the designs of the hinge connectors or Connection means 6 in Figs. 4 and 5 are different Variants conceivable in the representations 6 to 9 are recognizable. 6 and 7 show a two-part Design of the connecting means 6 with a Locking receptacle 10 engaging locking element 15. This Locking element 15 is attached via a flexible film hinge 15 ' the cover 1 or bottom cover 2 connected. The Film hinge 15 'consists of a comparable Material like the connecting web 6b. Also its manufacture coincides with the described procedure. additionally there is a trap strip 16, which one Jack strips 17 in the folded state after the 7 and 9 engages behind.

In the embodiment shown in Figs. 8 and 9 again a locking element 15 can be seen. This locking element 15 engages in an associated snap-in receptacle 14. To one To ensure a secure hold of the locking element 15 are Undercuts 18, 19 of the locking receptacle 14 are provided. In this case too, there is a trap strip 16 realized, which with a jack strip 17 in the already described way of representing the collapsed state of the box body K cooperates.

In contrast to the configurations according to FIGS. 4 and 5 are the connecting means shown in Figs. 6 to 9 or hinge connector 6 - as described - multi-part, at least two-part. This offers in the event that certain types of installation - For example, a length compensation via the Lanyard 6 - must be used.

For a simple revision of the entire roller shutter box or the roller shutter curtain 4 or to facilitate individual aggregates are one or more Separation points T are provided in the box body K. After this Embodiment in Fig. 1 is a separation point T in Bottom cover 2 and a separation point T in the back Cover 1 shown. Of course you can additionally a further separation point T in the bottom cover 2 or be realized in the rear cover 1. in the The area of this separation point T can be the associated one Open and close the bottom cover 2 with With the help of a rest seat connection R there (cf. the first enlarged section in Fig. 1). Anyway thereby dividing the bottom cover 2 possible for example, the roller shutter 4 in the case of a Repair simply from the otherwise closed To be able to remove box body K Another advantage this approach is that - when realized several separation points T in each Lids 1, 2 of the box body K - without problems Intermediate pieces can be used so that the Box body K (theoretically) any size - also subsequently - can accept.

Instead of that in Fig. 1 in the first Enlargement of rest seat connection R shown in the area of a separation point T in the bottom cover 2 here also a connection means 6 is used are, as shown in detail in Fig. 4 and at the separation point T in the rear cover 1 use place. In the same way as shown in Fig. 5, engages then the connecting means 6 in individual hollow chambers 7 of the associated cover 1, as the other enlarged section in Fig. 1 makes clear. To this In this way, the connecting means 6 do not only come to longitudinal connection of individual covers 1, 2 for use, but are also advantageous for Representation of the separation point T.

The connecting web 6b is made of an elastomer or a comparable resilient spring material, that the associated cover 1 is perfectly in the Area of the separation point T can be opened by the Lanyard 6 when folded slightly outwards Halves of the cover 1 from the associated hollow chambers 7 is removed. The same naturally applies in the event that such a separation point T with connecting means 6 a Access to floor cover 2 - instead of the click seat connection R - opened.
