Description

The invention relates to a device for suspending a curtain or the like in the form of a flanked in two support shoulders guide slot sliding rail slider, designed with an eyelet, hook or the like attachment portion and with a head, protrude from the sides facing away from each other supporting projections sliding support on the support shoulders and between the support projections and the attachment portion has a neck.

The invention also relates to a suspension device consisting of a curtain rail and such a slider.

Sliders are known from the prior art, which can be mounted at any x-anywhere on a curtain rail. For this purpose, the head of the slider is inserted with its oriented in the direction of extension of the guide slot support projections through the guide slot and then rotated by about 90 °, so that the support projections can come into contact with the support flanks. The DE 93 01 040 For this purpose, a split head of the slider before, where the two head halves can approach each other when turning the slider. Also the AT 410 169 B describes a glider in which the head and neck are split. The EP 0 722 686 A1 describes a slider with a solid head having a neck that can deform when rotated in the guide slot. A glider with a deformable neck also describes the US 2,848,734 , The DE 42 00 483 A1 describes a slider, which also has a two-part head, the two head halves must be moved to remove the slider from the curtain rail against each other. The DE 10 2009 025 771 A1 describes a slider whose head is also in two parts. The two headboards are but with a Bridge connected together, so that the two head parts can shift shearing against each other.

The invention has for its object to further develop a generic device nutzsvorteilhaft.

The object is achieved by the solution specified in the claims, wherein initially and essentially is based on the fact that the rotational movement precedes the displacement of the slider from an operating position into a removal position of a relative to the axis of rotation axial displacement. Alternatively, it may also be sufficient that only a rest is overcome. For this purpose, the neck has a first portion which adjoins directly to the supporting projections and which serves for the rotationally secured guidance of the slider in the guide slot when the supporting projections rest on the support shoulders. Adjoining this first section is a second section, the cross-sectional area of which is such that, when the support projections are spaced apart from the support shoulders, the slider is rotatable into a removal position in which the slider can be removed from the guide slot. The first section may preferably be realized as a polygonal section, wherein an edge pair of the polygonal section forms two mutually parallel guide flanks, which run parallel to the support shoulders with only a small distance in the operating position. Approximately offset by 90 ° to these guide flanks of the polygonal section side edges can form, which run parallel to the support shoulders in the rotated by 90 ° removal position. The second section directly adjoining the first section may be formed as a round section. It is essential that the cross-sectional area of the second portion has a maximum diameter which is less than the slot width of the guide slot, so that the slider can be rotated in an axially raised position. In this axially raised position, a between the second portion and the Attachment section arranged spacer web abut the underside of the curtain rail. The cross-sectional area of the spacer web is preferably designed so that it can not be pushed through the guide slot. The edge lengths of the polygonal section, however, are designed so that they are smaller than the slot width of the guide slot. The preferably designed as a polygonal section first section but has a Diagonalmaß, which is greater than the slot width, so that the slider can not be rotated in the guide slot with resting on the support shoulders supporting projections. The polygonal section may for this purpose have a square cross-section. The second neck portion, which is preferably formed as a round portion, may have a circular cross-sectional area. In terms of design, the second section may be formed by one or more radial cuts in the neck having a rectangular profile. The radial cuts are in the area of the corners of the polygonal section. Preferably, the second section is formed by four radial cuts. It is further preferred if at least one side wall of the radial cut forms a latching bead. The latching bead can, for example, be arranged in the region of a multiple edge of the polygonal section. In this area, the axial height of the second section is slightly smaller than the material thickness of a support shoulder forming rib of the curtain rail. This has the consequence that the lifted in particular for turning into the removal position slider can only be rotated after overcoming a catch from the operating position to the removal position. When turning into the removal position, the edge portions of the ribs, on which slide the support projections, enter the radial recesses. If this is possible only by overcoming a catch, such as by displacing a locking bead, a rotational displacement preceding axial displacement is not required, but beneficial. For this purpose, it is advantageous if the material of the slider is elastically yielding. Preferably, the slider is manufactured as a plastic molding. This can be done by injection molding. The axial height of the first neck portion is greater than that Material thickness of the support shoulder forming rib of the curtain rail and thus larger than the axial height of the second section. According to the invention, the slider can be inserted into the curtain rail in the manner of a bayonet catch and removed therefrom.

The in the FIGS. 1 to 6 or 7 to 11 or 12 to 16 illustrated embodiments differ from each other substantially only by the distance measure a, by which the side edges 10 are spaced from each other or by the distance b, by which the guide flanks 9 are spaced from each other, so that the slider 4 suitable for use in guide slots 2 different slot width f. That in the FIGS. 12 to 16 illustrated third embodiment also has in the neck 11, 12 a radial bore 15 for saving material or to reduce shrinkage during injection molding.

Incidentally, the sliders shown in the drawings have the following features:

The slider 4 is made of plastic and is made of the same material as an injection molded part. The slider 4 has a fixing portion which is formed in the embodiments as an eyelet 5. The eyelet 5 is adjoined by a spacer web 6, which forms a curved to a head 7 toward the distance surface having a floor plan, which is designed so that the spacer web 6 can not be inserted through the guide slot 2 of the curtain rail 1.

The middle section of the spacer bar 6 originates from an approximately cuboidal base, which initially forms a neck consisting of two sections 11, 12, to which a head 7 adjoins, which forms two support projections 8 facing away from one another. Again Fig. 17 can be seen, are support flanks 8 ', which are formed by the support projection 8, in the operating position on support shoulders 3, which are formed by ribs 13 of the curtain rail 1. The two mutually parallel support shoulders 3 are formed by the end portions of a respective rib 13 and define between them the guide slot 2, through which the neck 11, 12 of the slider 4th protrudes through. The slot walls 2 'of the guide slot 2 extend parallel to guide flanks 9, which are formed by a polygonal section 11 of the neck. The guide flanks 9 are parallel to each other and have a distance b which is less than the slot width f of the guide slot 2. Perpendicular to the guide flanks 9 extend side flanks 10 which have a distance measure a, which is also smaller than the slot width f.

However, the diagonal dimension d of the polygonal section 11 is greater than the slot width f, so that the slider of the in Fig. 17 shown operating position within the guide slot 2 can not be rotated.

At the formed in the exemplary embodiment as a square section polygonal section 11 which forms a guide section, closes in the direction of the spacer web 6, a second section 12, which is formed in the embodiment as a round section. The round section has a substantially circular cross section with a diameter e, which is smaller than the slot width f. The round section 12 is formed by a total of four radial cuts, which are introduced directly above the spacer web 6 in the corner regions of the neck.

The radial cuts have two mutually facing cutting walls, wherein the distance between the two cutting walls in the region of the corners of the square base is less than the material thickness of the web 13. This form Rastwülste 14 from. The axial height of the polygonal section 11, however, is greater than the material thickness of the rib thirteenth

Since the distance c of the two end faces of the support projections 8 is greater than the slot width f, the support flanks 8 'can rest on the support shoulders 3. Since the distance a of the longitudinal sides of the two support projections 8 is less than the slot width f, one in the in Fig. 20 shown removal position rotated slider 4 are removed from the guide slot 2.

The operation of the device according to the invention is exemplified with reference to the first embodiment with reference to FIGS. 17 to 21 explains:

The Fig. 17 shows the slider 4 in its operating position in which the supporting projections 8 rest on the support shoulders 3 of the guide slot 2. The two guide flanks 9 are located at the level of the slot walls 2 ', so that the slider 4 can be displaced in the extension direction of the guide slot 2 but can not be rotated within the guide slot 2. In the eyelet 5 hooks can be mounted on which a curtain, a curtain or the like is attached. The rail 1 has a hollow profile.

To remove the slider 4 from the curtain rail 1, it must be raised in the direction of arrow A, so that in Fig. 19 shown position is reached. In this position, the spacer web 6 is located on the underside of the curtain rail 1. The round section 12 is located at the level of the ribs 13. In this position, the slider 4 about the axis A in the in Fig. 20 shown removal position to be rotated. The formed by a wall of the radial cut Rastwülste 14 run on the rounded edges of the support shoulders 3. So it must be overcome a detent force to rotate the slider from the operating position to the removal position. After a 90 ° turn, the in Fig. 20 achieved removal position, in which the slider 4 can be removed in the axial direction of the guide slot 2.

The equipment of a curtain rail 1 with gliders 4 is done in reverse order. The slider 4 is first in the in Fig. 20 shown position inserted into the guide slot 2, wherein the connecting line of the two support projections 8 in the extension direction of the guide slot 2 has. The slider 4 is pushed so far with his head 7 in the curtain rail until the spacer bar 6 abuts the underside of the curtain rail 1. Then, accompanied by overcoming a stop, the slider 4 is rotated by 90 ° about the axis A, wherein the Rastwülste 14, the support shoulders 3 overflow and the support shoulders 3 in the incisions of the round section 12 occur until the in Fig. 19 shown position is reached. If now the slider 4 is released, it will be moved by gravity into the Fig. 17 lowered operating position shown, in which the supporting projections 8 rest on the support shoulder 3.

The Fig. 22 shows the cross section through a circular cross-section curtain rail 1 with a guide slot 2, the supporting shoulders forming ribs 13 are rounded, so the support flanks 8 'of the support projections 8 spaced from the edges 2' of the slot 2 rest on the ribs 13. Also in this curtain rail 1, the slider 4 can be brought by a 90 ° rotation in a removal position to remove it from the guide slot 2. Again, the rotational movement is preceded by a slight displacement of the slider 4 in the direction of the curtain rail 1 and the overcoming of a locking force.

Alternatively to the axial displacement of the slider but can also be provided that only a catch is overcome.
