Description

The present invention comprises at least one tube portion, the tube portion being held by a carrier device, and a tension member extending through the tube portion,
The tension member is secured to one end of the tube portion and is secured to the tensioning device supported thereon at the other end of the tube portion;
Furthermore, the tension member relates to a curtain rail that is held at a distance from the center line of the tube portion in consideration of the direction of the load to be carried by the tube portion.

Such a curtain rail with a tensioning device arranged on the inside is known from US Pat. Known curtain rails are held on their respective carriers at both ends, and tensioning devices are used to offset the deflection of the curtain rails when the suspended curtain is loaded downward. Is provided. In a known embodiment, the curtain rail shows a beam supported on two bearing bodies that can be seen mechanically, and a tension member that can fix the area of the beam below the flexure line between the bearing bodies. By supporting in this way, it is possible to reduce the deflection of the beam that increases toward the center between the support bodies in a state where a load is applied.
German Patent Application Publication No. 10047449

  The problem underlying the present invention is to provide a curtain rail of the type described above, which can use a tensioning device to offset the load and simplify the carrying device required for holding.

The problem is that in a curtain rail of the type described above, the carrier device consists of a single carrier, on which the two tube parts are coaxially opposed to each other with their adjacent ends. This is solved by the fact that the tension member is held in the tube portion so as to be shifted in the direction opposite to the load direction with respect to its center line (M) .

For the present invention, it is essential that only a single support must be provided to hold the curtain rail. The only carrier that forms the bearing body is provided so that the pipe part protrudes freely in contact with it, so that under load, the pipe part is increasingly towards its free end Trying to bend downward. Therefore, it is a problem to support the region in the tube part that is above the deflection curve, which is done in the tube part by the tension member, which is opposite to the load direction with respect to its centerline. And extends above the deflection curve. Thus, the area that has been deflected further downwards toward the free end of the tube portion due to the tension of the tension member is lifted again.
Features of advantageous embodiments of the invention emerge from the dependent claims.

  The invention is explained in more detail below on the basis of the figures of the examples.

  FIG. 1 shows in detail a curtain rail consisting of two tube parts 1a and 1b. In this case, the tube portions 1a and 1b are formed from cylindrical tubes. The tube parts 1a, 1b are fixed to a carrier device having only one carrier 2. According to the bracket mode, the carrier 2 consists of a rear plate 3 with a fixing unit 4 which can be fixed either to the wall or to the ceiling in the embodiment shown here. A plate 3 on the rear side of the carrier 2 is provided so that a figurine table plate 5 protrudes, and this figurine table plate carries a support 6 along its front edge. The support body 6 has a cylindrical outer peripheral portion, and the diameter thereof is equal to the diameter of the tube portions 1a and 1b, so that the tube portions 1a and 1b have end portions 7a and 7b fixed to the carrier 2, and The support 6 is securely connected. The exposed outer length of the support body 6 is equal to the width of the figurine table plate 5 of the carrier 2, and the plate 3 behind the carrier 2 is moved laterally through the figurine table plate 5. It protrudes. Therefore, it is possible to attach the carrier 2 sufficiently. This is at least true when the same or nearly the same load is transmitted to the carrier 2 from both tube parts 1a, 1b.

  As shown in FIGS. 1 and 2, the entire curtain rail is formed so that the end portions 7a and 7b of the coaxial tube portions 1a and 1b fixed to the carrier 2 are vertically extended with their tube axes extended. It can be configured symmetrically with respect to the standing plane. This is important for the carrier 2 and assumes a structure in which the lengths of the tube portions 1a and 1b are the same. However, the tube sections 1a, 1b can also be configured in various lengths, so that the load that must be accommodated on both sides by the carrier 2 is not equal. In each case, the tube parts 1a, 1b are plugged with caps 9a, 9b at their free ends 8a, 8b.

  FIG. 3 shows the internal structure of the tube part 1b which is identical to the internal structure of the tube part 1a (not shown). This internal structure is mirror-symmetric with respect to the tube part 1b in accordance with the symmetry of the curtain rail. Formed or provided. An insert 11b is disposed inside the tube portion 1b, and this insert is made of a tube that is more rigid than the tube portion 1b. A groove is added in the insert 11b along the outer sleeve line, and a rope-like tension member 10b is guided through the groove. The tension member 10b is spaced from the center line M of the tube portion 1b and is offset upward with respect to the center line M. Therefore, the tension member is disposed on the side of the tube portion 1b that is extended when a load is generated. Such elongation when the tube portion 1b is correspondingly twisted can be counteracted by the tension of the tension member 10b, in which case the tension member 10b is supported by the insert 11b and the lower inner wall of the tube portion 1b. Supported again in the area.

  The tension member 10b of the tube portion 1b is fixed to the support body 6. For this purpose, the support body 6 is provided with plug-in portions 13a and 13b projecting on the end surfaces facing each other, and the plug-in portions are stepped in the radial direction so as to correspond to the periphery of the support body 6. ing. Therefore, the end portions 7a and 7b fixing both the tube portions 1a and 1b can be inserted so as to be connected flush with each other outside the support body 6.

  In addition to FIG. 3, FIG. 4 shows the details of the plug-in portions 13a and 13b with the tensioning devices 15a and 15b provided therein, above which the tension members 10a, 10 b is fixed to the support body 6. The tension members 10a and 10b are fixed to the insertion portions 13a and 13b by the fixed ends 7a and 7b of the pipe portions 1a and 1b in the coaxial direction. Therefore, the tension members 10a and 10b are provided at both ends of the insertion portions 13a and 13b. It is necessary to provide turning devices 14a, 14b for Thereby, the tension members 10a and 10b necessarily occupy positions displaced in the radial direction with respect to the center line M of the pipe portions 1a and 1b.

  The tensioning devices 16a, 16b for the tension members 10a, 10b are provided inside the free ends 8a, 8b of the tube portions 1a, 1b, and the tension device for the right tube portion is shown in detail in FIG. In this regard, a housing 17b is required which is axially movable at the free end 8b of the tube portion 1b, to which the second end of the tensioning member 10b belonging is fixed using a tensioning device 18b. Has been. A turning device 19b is again provided here in the same way as in the insertion parts 13a, 13b of the support body 6, so that the tension member 10b can be inserted in the axial direction of the tension body 17b. The tension body 17b has a coaxial screw hole, and a fixing screw 21b is screwed into the screw hole. The fixing screw 21b is supported by the contact portion 22b by the head portion, and the contact portion is fixed at least in the axial direction and is fitted to the free end 8b of the tube portion 1b. The distance between the tension member 17b and the abutting portion 22b is adjusted for the tension member 17b according to the length of the tension member 10b so that the tension member 10b can be attached with the necessary tensile stress each time it is used. A sufficient sliding stroke is selected so that it can be used freely.

  FIG. 6 shows an alternative embodiment for the tube portions 1a, 1b of the curtain rail, here based on the tube portion 1b provided on one side of the carrier 2. FIG. Instead of the inserts 11a, 11b to be described previously, which hold the tension members 10a, 10b spaced from the center line M of the tube portions 1a, 1b, here the outer axial tension member line 33 is provided. Is provided. The tension member conduit 33 is molded into the material from which the tube portion is constructed. That is, it is molded integrally with the tube portion 1b. The tension member conduit extends near the outside line of the tube portion 1b outside the center line M of the tube portion. In the case of this embodiment, the deflection of the tension member 10b is not required in the fixed region of the support body 6 or in the fixed region of the tensioning device 16b. Therefore, the tensioning device 16b is provided on the outer side in the tube portion 1b in the axial direction and parallel to the axis.

  7 to 9 show details of the fixed unit 4. A vertically long fixed molding material 23 belongs to this, and this fixed molding material is fixedly provided on either the support body 6 or the bracket 5 in the rear. When the fixed molding material 23 is not integrally formed with the support body 6, the bracket 5, or the rear plate 3, here, as shown in FIG. 7, the fixed molding material is engaged with the rear plate 3. These can be screwed behind. The fixed molding 23 can be used to suspend the entire curtain rail into the wall plate 24, which is fixed in advance on the wall of the room or building, which is usually vertical, in advance. . For this purpose, a fixing screw 25 is provided, and this fixing screw passes through a through-hole on the corner side of the rectangular wall plate 24 in the plan view.

In order to accommodate the fixed molding material 23, the wall plate 24 has a vertically long notch 26, and this width is larger than the width of the vertical stationary molding material 23 including the girder 29 projecting sideways. Is also wide. The girder portion 29 extending to the long side portion is provided to be shifted to the rear side of the fixed molding material 23, and therefore, a vertically long fixing surface 28 is positioned on the fixed molding material 23 in front of the front side of the girder portion 29. is doing. An angle contour of the long side portion along the fixed molding material 23 formed by the fixing surface 28 and the front side of the beam portion 29 and a fixing screw 30 belonging to the wall plate 24 can be engaged. Thereby, the fixed molding material 23 is an edge region curved in a convex shape inside the notch (26) in the wall plate 24 with the long side portion 31 of the fixed molding material separated from the fixing screw 30. 27 to be fixed.
