Description

 Device for separating room areas of a room

The invention relates to a device for separating spatial regions of a room, according to the preamble of claim 1.

A device of the type mentioned is already known from WO2006 / 002705 Al. In the known device, the individual rails for the ceiling, the walls and the floor are formed such that they are mutually displaceable and relative to each other. The telescopically insertable and mutually extendable rail parts make it possible to completely separate a room area to be renovated from other room areas. The individual rail parts provide a peripheral frame resting on the ceiling, on the walls and on the floor, to which a film can be attached in order to enable a dustproof separation of the room areas. The stepless adjustment of the individual rails is possible in that two different types of rail profiles are provided, wherein the one profile engages in the other profile and the profiles are displaced against each other in this way. To set a specific rail length, the rail profiles are then screwed.

The known device is characterized by the fact that a gap-free and therefore dust-tight separation of spatial areas is readily possible.

The object of the present invention is to provide an alternative embodiment which is simple and inexpensive and at the same time ensures dustproofness.

The above object is achieved according to the invention in a device with the features of the preamble of claim 1, characterized in that adjacent rail parts only by mutual superimposition or superimposition of the rail parts and subsequent compression of the overlapping rail parts in rail transverse direction non-positively and / or positively connected to each other are, without a screw connection or the like is required as a separate connection means. in the Contrary to the device known from WO 2006/002705 A1, in which the rail parts are inserted into one another and then fixed relative to one another, in the device according to the invention, overlapping rail parts are connected by positive and / or non-positive force exclusively by compression. The insertion of the rail parts and also an insertion or removal of the interconnected rail parts is neither intended nor possible, since the rail parts after compression and the resulting connection are no longer movable relative to each other. This simplifies the assembly and disassembly of the rail consisting of a plurality of rail parts. To set the length of the rail on the ceiling or floor width or the wall height, it is only necessary to arrange a sufficient number of rail parts in the longitudinal direction next to each other and partially overlapping that from the overall arrangement of the rail parts, a rail with the desired width or Height gives. In the overlap area, the rail parts are then connected to each other in a force and / or form-fitting manner by compression, so that the rail is sufficiently stable. The positive and / or positive connection of the rail parts by superimposing and compressing allows a very simple structural design of the rail parts, which contributes to low manufacturing costs of the device according to the invention.

In the simplest case, already two rail parts may be sufficient to provide a rail that extends over the entire ceiling or floor width or wall height. Also, it is of course possible that more than two rail parts must be connected together to obtain the required width or height.

To achieve a predetermined length of the rail is provided in a preferred embodiment of the invention that after Zusammendrük- ken the overlapping rail parts these are at least substantially immovably interconnected in the rail longitudinal direction with each other. Due to the fixed adjustment of the rail parts to each other, a once set rail length remains constant even in the installed state. The degree of overlap is preferably infinitely adjustable, which means that the rail parts at each selected degree of overlap mit- can be connected to each other. This requires a corresponding design of the rail parts. In principle, however, it can also be provided that the rail parts can still be displaced relative to one another in the longitudinal direction even after being compressed, which permits a fine adjustment of the length of the rail to the required ceiling or floor width or wall height.

For non-positive and / or positive connection of the rail parts latching, crimping, clamping or Velcro connections can be provided. In principle, however, it is also possible for two rail parts to be connected to one another by an adhesive connection. Preferably, the connection of the rail parts is designed such that at a later date, an easy disassembly of the rail is possible without it being necessary to destroy the rail parts.

In a preferred embodiment, a first rail part has a base profile and a second rail part has a connection profile that is complementary to the base profile. The base profile and the connection profile may have complementary deformation regions such that only by compressing overlapping basic profile and connection profile results in a non-positive and / or positive connection. Preferably, the first rail part and the second rail part are each formed in one piece, which contributes to low manufacturing costs and simplifies assembly.

The first rail part and / or the second rail part can in principle have the same length over the entire length, which allows in a simple manner to connect the rail parts at each selected degree of overlap each other.

If a latching connection is provided in order to connect the overlapping rail parts by compression, the first rail part can have at least one outwardly directed latching projection on a preferably ceiling, floor or wall region of the rail part, ie directed outwards, which has a corresponding one Locking recess of the second rail part non-positively and / or positively connected. The dec ken, bottom or wall proximity of the locking projection ensures that the locking projection does not interfere with attachment of the film to the rail parts. In addition, the first rail part may have at least one inwardly directed latching recess in a preferably ceiling, floor or wall remote area of the rail part, wherein the latching recess of the first rail part with a latching projection of the second rail part non-positively and / or positively connected. The connection of the film with the rail part is not affected by the inwardly directed recess.

The latching projection and / or the latching recess may extend over the entire length of the rail part, which relates to both rail parts and allows connecting the rail parts at any degree of overlap.

In the assembled state of the rail, at least one engagement slot for a tool to be applied between the rail parts can be provided in the overlapping region of the overlapping rail parts, which can serve for simplified release of the connection during disassembly of the rail. This requires a corresponding design of at least one of the rail parts or a suitable profiling. The engagement slot may extend over the entire width of the overlap region and preferably be provided on the ceiling, floor or wall remote area of the rail parts. As a result, it is possible in a simple manner to separate interconnected rail parts from one another after use in order to store the device according to the invention in a space-saving manner. Moreover, a repeated connection of the rail parts and release of the same may be required if the selected degree of overlap must be corrected.

In order to be able to connect a film web, a tarpaulin or the like to the rail parts, the first rail part and / or the second rail part can have at least one adhesive tape extending at least partially in the longitudinal direction of the rail part, the adhesive tape being on the outside of the rail part is provided. Also, a multi-row arrangement of adhesive tapes is possible to allow the repeated use of the rail or the repeated joining of the film web or the tarpaulin with the rail parts. The width of the tape or tapes can extend at least over half the height of the rail part to provide a sufficient adhesive surface available. For receiving the adhesive tape, the rail part may have a recess extending in the longitudinal direction on the outside, wherein, preferably, the adhesive tape is inserted substantially flush in the recess. By pressing the film or tarpaulin to the adhesive surface then a connection between the film and the respective rail part is made. If the outer side of the rail part and the outer side of the adhesive tape are aligned, connecting the overlapping rail parts does not lead to obstruction by the adhesive tape. Moreover, it is understood that a peelable protective layer is provided in the original state on the tape.

For arranging between the ceiling rail and the floor rail, at least one, in particular, continuously adjustable support bar can be provided, by means of which a sufficient contact pressure between opposite rails is ensured. The height adjustment should preferably be infinitely, wherein it is offered for handling reasons that the rod in each set length can be determined via a screw connection. The support rod may for connection to the rails at its upper and / or lower end connecting means for non-positive and / or positive connection of the support rod having complementary further connection means of the rail, wherein the connecting means of the support rod and the other connecting means of the rail so ausgebil- det are that only by rotating the support rod about its longitudinal axis of the frictional connection and / or the positive engagement is effected in the profile. As a result, a particularly simple clamping of the support rod between opposite rails is possible.

The support bar as such features of the type previously described and the subsequent features of the support bar is of intriguing importance, i. regardless of the characteristics described above and the rail.

In one embodiment of the invention can be provided that the support rod has at one end a fastening part and pivotally with the fastening part is connected, wherein the fastening part connecting means for non-positive and / or positive connection with complementary further connection means of the rail and wherein, preferably, the connecting means of the fastening part and the other connecting means of the rail are formed such that only by turning the Attachment part about a longitudinal axis of the fastening part of the frictional connection and / or the positive engagement in the profile of the rail is effected. After the fastening part has been connected to a rail, it is possible to pivot the support rod relative to the fastening part. As a result, the bracing of the support rod between two opposite rails is simplified. Here it can be provided that the support rod is fastened at one end to the fastening part on a rail and at the other end has connecting means which make it possible by turning the support rod about its longitudinal axis at the other end of the support rod a frictional connection and / or to cause positive locking in the profile of the rail. The required physical training of the support rod or the fastening part on the one hand and a rail on the other hand will be described below only by the example of the support rod. It is understood that the features described can be provided according to a fastening part.

In a preferred embodiment, the support rod has at its end at least one projection as a connecting means, which can be fixed by rotation of the support rod about its longitudinal axis in an engagement region as complementary täres further connection means in the rail. This allows a positive and positive connection between the support rod and a rail in a simple manner. In this context, it is of course possible that the support rod has corresponding projections at both ends. If the head and the foot of the support rod are of the same design, then the support rod can be connected at any end to a rail, which further simplifies the assembly of the device according to the invention. Moreover, it is preferably provided that the support rod at each point of a rail in the engagement region of the rail can be inserted or screwed, which further simplifies the assembly. In a particularly simple and inexpensive embodiment, it is provided that the first rail part is formed in a U-shaped cross-section with two opposite side walls and that, preferably, the engagement region for the support rod between the bottom of the rail part connecting the side walls and on the inside Side walls provided opposite projections is formed. The extensions extend in the longitudinal direction of the first rail part, in particular over the entire length, so that the support rod can be connected in the longitudinal direction of the rail part at any point with this.

On the projection of the support rod arcuate portion extending outer bevels may be provided. This makes it possible with little effort to connect the support rod by screwing with a rail or to clamp in the rail.

The support rod may have on opposite shell sides in each case at least one projection formed on the support rod, wherein the opposing projections are arranged in a common plane and span a common cross-sectional area with two parallel straight outer sides and two diagonally opposite arcuate outer sides. Moreover, the cross-sectional area defined by the contour of the protrusions may have two diagonally opposite edges with substantially mutually perpendicular outer sides, whereby after connecting the support bar to the rail by rotating the support bar about its longitudinal axis, at least the edges of the protrusions bear against the side walls, what leads to the clamping of the support rod in the rail. In order to allow easy insertion of the support rod with one end into the rail, the maximum width of the cross-sectional area substantially corresponds to the distance between adjacent side walls of the rail, wherein the minimum width of the cross-sectional area should be smaller than the distance between the above-described extensions or the other extensions on the rail.

In the support rod, preferably on at least one support rod end, at least one spring means acting in the longitudinal direction of the support rod may be provided. Such a spring means not only facilitates the insertion of the Support rod, but also ensures a permanent pressing of the rail in question.

Preferably, the first rail part has two identically formed side walls, which are arranged mirror-symmetrically to one another. This makes it possible in a simple manner, if necessary, to connect the second rail part with the one side wall or with the other side wall, which further simplifies the mounting of the rail. For example, each side wall may have a latching projection and, if appropriate, a latching recess, latching projections and latching recesses of opposite side walls each being arranged opposite one another, so that a mirror-symmetrical structure of the first rail part results.

Further preferably, the recesses are provided at the free end of the side walls and the extensions in the ceiling, floor or wall near the side walls, wherein the clear distance between opposite side walls in height of the recesses is greater than the clear distance between the extensions of the sidewalls. As a result, the insertion of the support rod into the engagement region of the first rail part is not hindered by the inwardly directed latching regions on the side walls, which are provided to form a non-positive and / or positive connection.

If the first rail part has a U-profile, then preferably each side wall on the outside can have a depression or a groove, which is provided for receiving an adhesive tape. As a result, the first rail part can, if necessary, be connected from one side or the other side with a foil or covering tarpaulin. This contributes to a simplified separation of a space area and allows repeated use of the rail. Incidentally, the second rail part may be formed in the same way with respect to the receptacle, wherein the second rail part at least on its outside, optionally also on its inside has a corresponding recess. In this case, the outer recess serves to receive an adhesive tape, while the inside recess ultimately serves to accommodate in this area the adhesive tape arranged on the outside of the first rail profile in the inner recess and does not hinder the connection between the two rail parts.

Preferably, the recess between the locking projection on the ceiling, floor or wall near the end of the side wall and the recess at the free end of the side wall is provided. The width of the depression preferably corresponds at least to the width of the adhesive tape or a plurality of adhesive tape strips arranged side by side in the longitudinal direction.

The rail parts may be made of plastic by extrusion or be prepared, wherein at least one sealant can be sprayed to rest against the Dek- ke, the floor or the wall immediately after the extrusion of the rail part. This contributes to very low production costs of the rail parts. The sealants largely preclude the passage of dust particles between the ceiling, floor or wall and the rail.

In order to ensure a sufficient contact pressure of the rail to the ceiling and / or the wall and / or the floor, at least one diagonal strut can be provided for preferably releasable attachment to the wall rail and the ceiling rail or floor rail. According to the invention it is provided that are provided on preferably both ends of the diagonal brace clamping means for fixing the diagonal brace in the rails and that the clamping means are held captive on the diagonal brace or formed integrally therewith. Due to the clamping means, it is possible in a simple manner to clamp the diagonal strut in the corner region between the ceiling and wall rail or wall and floor rail. In addition, a simple disassembly of the rail assembly is possible. The attachment of the clamping means on the diagonal brace ensures a high level of user comfort.

In particular, there are a variety of ways to design and further develop the device according to the invention, reference being made on the one hand to the dependent claims and on the other hand to the following description of preferred embodiments of the invention with reference to the drawings.

In addition, diagonal struts 6 are provided in order to ensure a sufficient contact pressure in the corner region between an adjacent ceiling rail 2a, 2b and the wall rails 4 or between the wall rails 4 and the floor rails 3a, 3b. Not shown in detail that the diagonal struts 6 at both ends clamping means for fixing in the rails 2a, 2b, 3a, 3b, 4, wherein the clamping means are held captive on the diagonal struts 6.

Hereinafter, the structure of the ceiling rail 2a will be described by way of example, wherein the structure of the ceiling rail 2a shown in Fig. 2 substantially corresponds to the structure of the bottom rail 3a and the structure of the wall rail 4. In the exemplary embodiment shown in FIG. 1, the ceiling rail 2 a is composed of two rail parts 7 with a basic profile and a rail part 8 with a connecting profile. In this case, it is provided that adjacent rail parts 7, 8 are interconnected by mutual superimposition of the rail parts 7, 8 in the rail longitudinal direction and subsequent compression of the overlapping portions of the rail parts 7, 8 in the rail transverse direction with force and form fit.

The ceiling rail 2a and the bottom rail 3a and the wall rails 4 have the same rail parts 7, 8, which greatly simplifies the assembly of the device 1. The ceiling rail 2b and the bottom rail 3b have a single rail part 7 whose length substantially corresponds to the depth of the space which is separated. In principle, it is also possible here to provide a plurality of rail parts 7, 8 in order to be able to separate a space region with greater depth. The first rail part 7 has a U-profile with two side walls 9 and a bottom 10. The second rail part 8 is designed as a leg and has a side bar 11 with an extension 12 at the end near the ceiling. On the extension 12 and the bottom 10 sealing lips 13 are welded to preclude the passage of dust particles between the ceiling, not shown in Fig. 1 and the ceiling rail 2a in the assembled state.

In the area near the ceiling, latching projections 14 are provided on the side walls 9 of the first rail part 7 on the outside, which are non-positively and positively connected to a latching recess 15 on the side web 11 of the second rail part 8. At its free end, each side wall 9 has a latching recess 16, which is non-positively and positively connected to a complementary latching projection 17 on the side web 1 1 of the second rail part 8.

For connecting a support rod 5 shown in FIG. 1 with the first rail part 7, it is provided that the support rod 5 is inserted with one end in the engagement region 20 and then rotated about its longitudinal axis. This results in a force and positive engagement between an outer projection at the end of the support rod 5 and the projections 21, wherein the thickness of the projection is greater than the height of the Eingriffsberei- Ch 20 corresponds. In order to enable a simple insertion of the support rod 5 with its end in the engaging portion 20, it is further provided that the clear distance dl between the opposite side walls 9 in height of the recesses 16 is greater than the clear distance d2 between the opposite extensions 21st

FIG. 3 shows a simplified embodiment of a ceiling, floor or wall rail 24 formed from two rail parts 22, 23. The rail 24 substantially corresponds to the ceiling rail 2a shown in Fig. 2, wherein the connection of the rail parts 22, 23, however, only a latching connection in the ceiling, floor or wall area is provided. The rail part 23 is formed substantially L-shaped with two legs 23a, 23b and has on the leg 23a a latching recess 25, in the mounting state of the rail 24, a latching projection 26 of the rail part 22 engages. The horizontal leg 23b of the rail part 23 has at its free end on an extension 27 which rests in the assembled state of the rail 24 against the ceiling, the floor or the wall and is provided as a support for the rail part 23.

In Fig. 4 the profile of a rail part 7a is shown in cross section. This profile differs from the profile of the first shown in FIG

Rail part 7 characterized in that in addition to the extensions 21 on opposite two further extensions 21a are provided, which, however, protrude less far than the extensions 21. In this case, a groove 21b is provided on each side wall 9 between the respective extension 21 and the respective extension 21a, wherein the clamping with the projections (not shown) can be done on the support rods in the grooves 21b. Moreover, the further extensions serve 21a as reinforcement.

In Fig. 5, the profile of a second side part 8a is shown. A difference from the embodiment shown in FIG. 2 is that a recess 18a of small depth is provided on the inside 8b of the second rail part 8a, while on the outside 8c a further recess 18b is provided for receiving and arranging an adhesive tape. The depression 18a ultimately serves to accommodate the possibly protruding region of the adhesive tape arranged in the recess 18 of the first rail part 7, 7a, so that the locking can be carried out without difficulty.

FIG. 6 shows a partial cross-sectional view of a support bar 5 fastened to a rail part 7b of the ceiling rail 2a, 2b. The support rod 5 has, for example, at the upper end a fastening part 28 with a handle portion 29. The fastening part 28 further comprises connecting means for non-positive and / or positive connection with complementary further connection means of the rail part 7b, wherein the connecting means of the fastening part 28 and the further connection means of the rail part 7b are formed such that only by rotating the fastening part 28 around its longitudinal axis Yi the frictional connection and / or the positive engagement in the profile of the rail part 7 is effected. When rotating the handle portion 29 engage in Figs. 6 and 7 shown projections 30, 31 and the further projection 36 and an unillustrated further projection of the fastening part 28 in engagement portions 32, 33 and further engagement portions 37, 38 of the rail part 7b, as will be described in more detail below will be received. Here, it is so that the connecting means of the fixing member 28 correspond to the connecting means of the support rod 5, which are provided at the lower end of the support rod 5 for non-positive and / or positive connection of the support rod 5 with the rail part 7b of the bottom rail 3a, 3b. 6 and 7 is also shown that the support rod 5 and the fixing member 28 are hingedly connected together by a hinge 34, so that it is possible after attachment of the fastening part 28 with a ceiling rail 2a, 2b, the support rod. 5 to pivot relative to the rail part 7b. Thereby, the attachment of the support rod 5 with the free end on a bottom rail 3a, 3b is facilitated.

After fixing of the mounting part 28 to the rail part 7b a ceiling rail 2a, 2b, the support rod is fastened in a vertical position overall introduced and then by rotating around the longitudinal axis Y ₂ with its lower end in a rail part 7b of a bottom rail 3a, 3b. 5 The rail parts 7b of the ceiling rail 2a, 2b on the one hand and the bottom rail 3a, 3b on the other hand are the same. In principle, the support rod 5 with the fastening part 28 can therefore also be fastened to a bottom rail 3a, 3b or to a wall rail 4.

In Fig. 8, the free end of the support rod 5 is shown, wherein the support rod 5 is fixedly connected by turning with the rail part 7b. For this purpose, the support rod 5 has at its free end projections 30, 31 and further projections 35, 36, which correspond to the projections 30, 31, 35, 36 on the fastening part 28. The projections 30, 31 engage in engagement regions 32, 33 of the rail part 7b, while the projections 35, 36 engage in the further engagement regions 37, 38. The rail part 7b has oppositely arranged projections 39, 40 with the same width. The projections 39, 40 are provided on the inner sides of the side walls 41, 42 of the rail part 7b. The projections 39, 40 on the one hand and the projection 40 and a bottom 43 of the rail part 7b on the other hand define the engaging portions 32, 33 and the other engagement portions 37, 38. As has already been pointed out, the lower end shown in FIG Support rod 5 and the top for attachment to the rail part 7b provided end of the fastening part 28 is formed equal, which allows for the same design of the rail parts 7b of ceiling rail 2a, 2b and bottom rail 3a, 3b, if necessary, the fastening part 28 or the support rod 5 with the ceiling rail 2a, 2b or the bottom rail 3a, 3b to fix. In Fig. 8 is further shown that the support rod 5 in the region of the free lower end of a longitudinal direction Y _{2 of} the support rod 5 acting spring means 44 and acting against the spring means 44 retaining pin 47, wherein the retaining pin 47 fixed to the outer part 46 connected and in a slot 47 a of the inner part 45 is movably guided. Thereby, the support rod 5 can be clamped in a simple manner between a ceiling rail 2a, 2b and a bottom rail 3a, 3b.

The projections 30, 31 and the further projections 35, 36 have in the longitudinal direction of the rail part 7b run-on slopes 48, 49, which are inclined in the direction of the bottom 43 of the rail part 7b. The bevels 48, 49 simplify screwing in the projections 30, 31 or the further projections 35, 36 into the engagement regions 32, 33 or the further engagement regions 37, 38 of the rail part 7b.

From Fig. 10 it follows that the two arranged in a common plane projections 30, 31 on the one hand and the other projections 35, 36 on the other hand (not shown) has a cross-sectional area with two parallel opposite straight outer sides 50, 51 and two diagonally opposite arranged arcuate outer sides 52, 53 span. The further projections 35, 36 correspond to the projections 30, 31. The cross-sectional surface also has two diagonally opposite edges 54, 55 with substantially perpendicular converging outer sides 51, 52 and 50, 53, wherein after connecting the support rod 5 with the rail part 7b by rotation of the support rod 5, the projections 30, 31 at least in the region of the edges 54, 55 bear against the side walls 41, 42 of the rail part 7b. The maximum width bl of the cross-sectional area in the region of the central transverse axis Xj of the support rod 5 essentially corresponds to the distance between the adjacent side walls 41, 42 of the rail part 7b. On the other hand, the minimum width b2 of the cross-sectional area in the direction of the center transverse axis X ₂ is smaller than the distance between the projections of the rail part 7b. This makes it possible in a simple manner, at a first position of the support rod 5 insert it with its free end in the area between the opposite projections 39 of the rail part 7b and by rotating at least the inner part 45 of the support rod 5 about the longitudinal axis Y ₂ in a second Position a force and form a positive connection between the support rod 5 and the rail part 7b. It is understood that the intended type of connection between the support rod 5 and the rail part 7b on the one hand and the connection of the fastening part 28 with the rail part 7b on the other requires that the support rod 5 at least two mutually about the common longitudinal axis Y ₂ rotatable support rod parts 45, 46th having.
