Description

The present invention relates to a surface curtain device according to the preamble of claim 1.

Such a surface curtain device is from the document WO 2011/047825 A2 known. It has a ceiling rail with at least one guide channel. In a groove of a carriage profile, a carrier is rotatably inserted, which has a mold recess. In this a bearing shaft is rotatably received, at the upper end of a pair of rollers is freely rotatably mounted, which is movably supported in the guide channel.

Moving the carriage with the attached curtain track causes noise and the installation is time consuming and takes up space.

From the pamphlets CH 675960 A5 and CH 676193 A5 Curtain sliders are known with elastically movable sliding lips, which allow the insertion of the curtain sliders from below into the rail.

It is an object of the present invention to provide a panel curtain device which is quickly mountable and quiet in moving the carriage.

This object is achieved with a generic surface curtain device having the features in the characterizing part of claim 1.

The inventive surface curtain device has a ceiling rail with at least one guide gap having a guide channel. Usually, the guide channel has a C-shaped cross-section, wherein the guide gap is lying down.

A carriage has a carriage profile, a carrier and at least one guide element, preferably two identically designed guide elements, for movably mounting the carriage in the guide channel or on two guide channels. The carriage profile has a, preferably in cross-section C-shaped, in the direction of the guide channel, thus open towards the top groove and integrally formed with the groove defining the groove wall fastening part. The latter is preferably designed as a web and serves to attach a curtain track on the carriage profile.

On the preferably parallelepiped, inserted in the mounted state in the groove carrier a mold recess is formed, in which a bearing shaft of a guide element is received. The bearing shaft and thus the guide element are freely rotatable on the carrier about the axis of the bearing shaft.

The adjoining the bearing shaft and integrally formed with this head has a head portion whose width is smaller than the guide gap, so that the head part can be inserted through the guide gap into the guide channel. On the head part sliding lips are formed, which protrude in the rest position laterally on both sides of the headboard. The sliding lips are designed to be elastically movable so that they pass through the guide gap when the head part is pushed in dodge in the guide channel in the direction of the head part and, once they are moved through the guide gap, can independently move back to its rest position, then the guide element slidably supported on the guide channel. The carriage is thus by means of the guide element in the guide channel from below clickable.

In contrast to the prior art, in which the guide elements of the carriage are inserted in the longitudinal direction of the guide channel in this, with the inventive solution for mounting the carriage to the ceiling rail, thanks to the possibility of clicking from below, less space and less time needed ,

Preferably, the mold cavity is open towards one of the two longitudinal sides of the carrier, so that the bearing shaft of the guide element can be pushed into the mold cavity from the side. The carrier is inserted together with the bearing shaft inserted into it in the longitudinal direction of the groove of the carriage profile in this. Since the longitudinal side of the carrier, in the mounted state, is located in the interior of the groove, the bearing shaft is trapped in the mold recess and freely rotatably mounted therein about its axis.

Preferably, a cap is formed on the carrier frontendseitig. The carrier can be inserted with the cap trailing in the groove of the carriage profile, preferably as far as the cap rests on the carriage profile. It then closes this seen in the longitudinal direction of the carriage.

Preferably, the cap is flat and extends to the free end edge of the Fastening part or bridge and it protrudes laterally over the bridge. The cap thus protects the attachment part or web and the attachment of the curtain track to this and gives the carriage an aesthetic view.

The carriage preferably has a carrier with a guide element at its two end-side end regions in the longitudinal direction. The carriage is thereby held in the horizontal direction stable in the guide channel or in two guide channels displaceable.

Preferably, at least one cap of the carriage on a cantilever-like from the cap protruding driver part. This is intended to intervene in an inserted in another guide channel of the ceiling rail carriage between the cover caps. As a result, the other slide is taken during sliding sliding of a carriage in the guide channel as soon as the driver part rests against one of the cover of this other carriage.

Preferably, the carrier has a through hole with a thread. In this a screw, preferably a grub screw is used, which is engageable by inserted into the groove of the carriage profile carrier through the opening of the groove by means of a screwdriver to secure the carrier to the carriage profile.

Preferably, the web is formed areally and it is off-center of a groove forming in cross-section C-shaped part of the carriage profile. Preferably, the part of a Velcro connection is attached to the web surface, for example by gluing, the other Part is located on the curtain track. This is thus very easy attachable to the carriage and away from it again.

Seen in plan view, the mold cavity is preferably U-shaped, wherein the opening is located on the longitudinal side. Furthermore, the mold cavity preferably extends from the top to the bottom of the carrier. Further, the mold recess is preferably formed in the direction of the top against the bottom by a shoulder widening. The bearing shaft engages under a shoulder on the shoulder, whereby the carrier is held on the bearing shaft and thus on the guide member and the bearing shaft is freely rotatable relative to the carrier about its longitudinal axis.

Preferably, the bearing shaft is circular cylindrical in shape and has, as seen in its axial direction preferably approximately centrally, a circumferential groove. The base thus extends from the free end of the bearing shaft to this circumferential groove. From this circumferential groove to the head part of the diameter of the shank is smaller than the gap of the groove of the carriage profile and, moreover, the length of the bearing shaft from the groove to the head part is greater than the thickness of the gap of the groove bounding legs of the carriage profile. This ensures in a simple manner that the guide element can rotate around its axis defined by the bearing shaft axis of friction in the carrier.

Preferably, the head between the bearing shaft and the engaging through the guide gap in the guide channel of the ceiling rail head portion, seen in the longitudinal direction of the carriage, laterally above the head part projecting Side flanges on. On the one hand, these prevent the entire head from moving into and becoming wedged in the guide gap, while at the same time ensuring a slidable reception of the profile delimiting the guide channel between itself and the sliding lips.

The guide element is slidably guided on the guide channel, but not rotatably guided.

Preferably, the head part, seen in side view, yoke-like design. On the two side legs of the yoke interconnecting Jochsteg the sliding lips are integrally formed on the inside and hinged to the Jochsteg film-hinge-like. This allows on the one hand when inserting the head part and thus the yoke through the guide gap in the guide channel, the elastic moving back of the sliding lips in the space delimited by the yoke and ensures a support of the sliding lips, if they are supported in the interior of the guide channel on this sliding.

The head can also be designed as this from the documents CH 675 690 A5 and CH 676 193 A5 is known.

Preferably, the ceiling rail has at least two parallel guide channels. The one guide element of the carriage is slidably received in one of the two guide channels and the other guide element in the other of these two guide channels. If a plurality of carriages are arranged on the ceiling rail in this way, these overlap and the associated curtain tracks overlap like scales.

Preferably, however, it is also possible that both guide elements of the carriage in the same guide channel are slidably received while the guide elements of another carriage are received in the other guide channel.

The ceiling rail preferably has an aperture in order to cover the guide channels and preferably also the slide or slides from the visible side. Preferably, the ceiling rail is integrally formed profile-like.

An Indian Fig. 1 shown carriage 10 has a carriage profile 12 with a groove 14 in the direction towards open at the top and a fastening part 16 'forming web 16, a support 18 with a molded-on cap 20 and a guide element 22nd with a head 24 and one of them projecting downwardly against the bearing shaft 26.

The carriage profile 12 is a portion of an example extruded plastic profile and thus formed in one piece.

The groove 14 forming or delimiting groove wall of the carriage profile 12 is in cross-section C-shaped, in the direction open at the top and from the two side legs 30 interconnecting, underlying connecting leg 32 is in the direction down against the flat-shaped web 16 from. This is arranged laterally offset relative to the center of the connecting leg 32.

The mutually facing free end portions of the side legs 30 are designated by 30 '.

The carriage profile 12 has the same cross-section over its entire length.

On the, in consequence of the laterally offset arrangement of the web 16, longer side of the connecting leg 32 associated surface of the web 16 is attached to this a first floor 34 of a hook and loop fastener 36, for example by means of gluing. A second floor 38 of the Velcro connection is arranged on a curtain track 40, which can be fastened by means of the Velcro connection 36 in a simple manner on the slide profile 12 and from this again removable.

The carrier 18 is cuboidal and its cross section is chosen so that it in the longitudinal direction L of Groove 14 and thus of the carriage profile 12 in this as possible inserted without play.

The carrier 18 has a mold recess 42 which, seen in plan view, is U-shaped and, in the direction shown in the longitudinal direction L, is open towards the left longitudinal side 44 in the exemplary embodiment shown.

The mold recess 42 extends from the top of the carrier 18 to its underside and widens from top to bottom stepwise to form a shoulder 46th

At the trailing end side of the carrier 18, viewed in the longitudinal direction L, a cover cap 20 is arranged on it. The cap and the carrier 18 are preferably formed integrally with each other in one piece.

In the illustrated embodiment, the cap 20, seen in side view and thus seen in the longitudinal direction L, a rectangular shape with rounded corners. The width of the cap 20 corresponds to the greater width of the carriage profile 12 and the height corresponding to the greater height of the carriage profile 12, from its upper end to the underlying free end edge 47 of the web 16th

When inserted into the groove 14 of the carriage profile 12 in the longitudinal direction L carrier 18 thus completes the cap 20, the carriage 10 from.

Between the mold recess 42 and the cap 20, the carrier 18 has a threaded bore 48 extending from its upper side to its underside with a grub screw 50 arranged therein. In the groove 14th inserted support 18, the grub screw by means of a screwdriver from above through the longitudinal gap 52 of the groove 14 through rotatably fixed to the carrier 18 on the carriage profile 12.

From the head 24 of the guide member 22 in the downward direction protruding circular cylindrical bearing shaft 26 can be inserted from the longitudinal side 44 forth in the recess 42 open towards this recess.

The bearing shaft 26 has, seen in its axial direction, approximately in the middle in the direction of an outwardly open circumferential groove 54, which limits a reaching from her to the lower free end of the base 56 of the bearing shaft 26. In the inserted state, the base 56 is located between the shoulder 46 and the underside of the carrier 18, wherein it is offset upwardly with respect to this bottom.

The base 56 thus engages under the shoulder 46 and cooperates with this, the slide profile 12 and the carrier 18, together.

The diameter of the circumferential groove 54 is slightly smaller than the clear width of the mold recess 42 between the shoulder 46 and the top of the carrier 18th

The length of the bearing shaft 26 from the circumferential groove 54 to the head 24 is greater than the thickness of the groove 14 at the longitudinal gap 52 bounding, one another directed leg portions 30 'of the carriage profile 12th

During assembly, the guide element 22 is inserted from the longitudinal side 44 into the mold recess 42 as a first step, so that the base 56 the Shoulder 46 engages under, and then the carrier 18, in the longitudinal direction L, inserted into the groove 14 of the carriage profile 12, preferably until the cap 20 rests against the end face of the carriage profile 12. The guide element 22 is then freely rotatable, but otherwise secured to the carrier 18 fixed. As the last step for mounting the carriage 10, the grub screw 50 is tightened.

The head has an upper head part 58, which is designed as a yoke 60. At a yoke web 62, which is above and connects the two yoke side parts 64 to each other, two sliding lips 66 are formed on the underlying and therefore inner side of the yoke 60 (is that correct?). These are seen in the longitudinal direction L side of the yoke 60 and thus the head part 58 before. In her in the Fig. 1 shown rest position are the sliding lips 66 with their top on the yoke web 62 at. However, they are hinged hinge-like yoke bridge 62 so that they are hineinschwenkbar in the space limited by the yoke 60 (is that correct?).

Next, the head 24 between the bearing shaft 26 and the head part 58 and yoke 60 on both sides of side flanges 68 which project laterally beyond the head portion 58 and thus the yoke 60.

Seen in plan view, the head part is formed approximately square, wherein the yoke in the plan has a rectangular shape to rotatably on a ceiling rail 70 can be performed, which in conjunction with the FIGS. 2 to 4 is explained.

Fig. 2 shows an end portion of a finished mounted carriage 10. Above the carriage 10 is a Ceiling rail 70 shown with two parallel to each other guide channels 72. The guide channels 72 forming walls of the ceiling rail 70 are C-shaped in cross-section and form a downwardly towards the carriage 10 open toward the guide gap 74. By vertical lifting of the carriage 10 of the head part 58 can be inserted into the guide channel 72. The sliding lips 66 are elastically swung back into the yoke 60 through the guide channel 72. As soon as they are released by the mutually facing legs of the guide channel 72, they pivot back into the in the due to their elasticity Fig. 1 and 2 shown rest position back; see also 3 and 4 , By slightly lowering the carriage 10, the sliding lips 66 come on the inside of the guide channel 72 to the plant and hold there sliding the carriage 10th

The movement of the head part 58 into the interior of the guide channel 72 is limited by the side flanges 68. In the assembled state thus the mutually facing, the guide channel 72 forming webs between the side flanges 68 and sliding lips 66 are trapped.

The width of the guide gap 74 is greater than the width of the head part 58 or yoke 60, but measured smaller than the width of the head 24 via the side flanges 68.

The head 24 is against rotation in the guide channel 72, but slidably received noise.

Fig. 3 shows a profile-like integrally formed ceiling rail 70 with two mutually parallel guide channels 72. The ceiling rail 70 is in known

Attached to a crash board 76. On the side facing away from the crash board 76, the ceiling rail 70 has an aperture 78 which visually covers the guide channels 72 and the slides 10 slidably supported in the guide channels 72, so that, viewed in the direction of the aperture, only these and those on the slide 10 fixed curtain tracks 40 are visible.

Fig. 3 shows a carriage 10 with at its two longitudinal ends depending on a guide element 22, wherein the one guide member 22 in one of the guide channels 72 and the other in the other guide channel 72 is slidably supported.

In the same way, a plurality of carriages 10 may be supported in the two guide channels 72. The scale-like overlap of the carriages 10 and the respective curtain tracks 40 can thus be changed and the carriages 10 with the curtain tracks 40 can be pushed together to form a narrow, scale-like stack.

Fig. 4 shows a likewise attached to a crash board 76, integrally formed, profile-shaped ceiling rail 70 with three parallel guide channels 72 and also a diaphragm 78th

In this embodiment, the two guide elements 72 of a carriage 10 are mounted in each guide channel 72. The carriages 10 are thus parallel to one another; Of course, more than one slide 10 may be supported in each guide channel 72.

In the in the Fig. 4 Center and the slide 10 shown therefrom are dashed to the side cantilever-like projecting, integral and integral with the cap 20 molded driver parts 80 indicated. These driver parts 80 engage with their free end region in each case at the right thereof adjacent slide 10 between the caps 20 a.

The respectively in Fig. 4 invisible second cover 20 is formed without driver part 80.

For example, in the Fig. 4 Depending on the sliding direction, one or the other cap 20 takes along the driver part 80 of the adjacent carriage 10, shown on the right-most side of the slide 10 in the relevant guide channel 72. The same thing happens when one of the caps 20 of the middle carriage 10 comes to rest on the driver part 80 of the carriage 10 shown on the left.

With this embodiment, therefore, all the carriages 10 can be moved into a stack-like position by the displacement of the curtain track 40 shown, for example, on the far right. By moving in opposite side, one slide 10 after the other are taken one by one to close the curtain.
