EP2272406A2 - Window clip for window hanging - Google Patents

Abstract

The window tie-clip (1) is made of a flexible-spring profile passed at a framework of a window, where profile has a transverse thigh. The width of a hook is constant in its floor area (63) and a transient area (62) following it, which constantly tapers in tapering range (64) following it. An independent claim is also included for a pleating unit.

Description

The invention relates to a window clip according to the preamble of claim 1.

Such window clips are used for fastening window hangings, such as curtains or pleated blinds, or for hanging decorative objects on the frame of a window.

State of the art

Such a window clip is from the German utility model DE 20 2005 007 376 U1 known. This window clip consists of a profile with a transverse leg, on both sides of a free leg is formed. A first of the two free legs engages behind the frame of the window in the assembled state and rests on the back of the frame. The second of the two free legs abuts against the inside of the frame and has its front a hook whose free end portion acute angle points in the direction of the plane defined by the surface of the second free leg.

The window clip according to the prior art offers the possibility to attach window hangings or decorative objects to a window without damaging the window frame through a hole. The introduction of holes in window frames is often problematic especially in rental housing. In addition, through drilling the insulation of the window frame can be affected.

The U.S. Patent 1,053,586 shows in the Figures 3 and 4 a hook for fixing a curtain rod, which is bolted to a window frame. This is often not practical, especially in rental apartments.

The DE 200 05 703 U1 and the U.S. Patent 1,455,166 show each attachment options for curtains u. Like., Which are clamped on window frames can. These attachment options consist of two hooks, which are placed on two opposite Holmen a window frame and braced against each other.

The DE 20 2005 013 537 U1 shows a further attachment for a window hanging window frames. As with your window clips here brackets are mounted on spars of window frames, being stretched between the brackets a cord for a curtain. The string is fixed to bolts of the brackets.

One form of window hanging is a so-called pleated installation. A pleated installation comprises at least one, usually two, pleated installation guide (s), which are mounted parallel to the window pane and on which a sunshade can be displaced along the window. The Plisseanlagenführung usually consists of with eyelets on the inside of the Fensterrrahmens attached ropes or wires. If the upper and the lower end of the sunscreen are pushed together, then the sunshade sets accordion-like to a package and barely obstructs the incidence of light through the window. If the two ends are maximally pulled apart unfolds the sunscreen and you can reach the maximum sun protection effect of the pleated blind.

Although the window clip according to the prior art allows for easy attachment of curtains or the hanging of decorative items, but attached pleated systems tend to beat against the window, which can not be accepted due to the associated noise pollution in living or office space.

Presentation of the invention

The invention has for its object to provide a window clip can be attached to the Plisseeanlagen so that they can not beat against the window. It should be noted that an increase in the distance between the pleated system and the window pane leads to the fact that when the pleated system is lowered, the window handle can no longer be actuated because it then collides with the pleating installation.

This object is achieved by a window clip according to claim 1. Advantageous embodiments of the invention are specified in the dependent claims.

The window clip according to the invention comprises an adapted to the frame of the window resilient profile with a transverse leg, on both sides of a leg. A first of the two legs engages behind the frame of the window in the mounted state and rests on the back of the frame. The second of the two legs abuts the front of the frame. At its front side, the window clip has at least one hook whose end region is preferably parallel to the second leg of the profile. The width of the hook is constant in its foot area and in its transition area. The width and tapers steadily in a subsequent rejuvenation area. The adjoining end portion of the hook has a constant width and opens into a point of the hook, which can be pointed, rounded or flat. As a result of the hook width tapering in the transition region, a fastening device for a pleat system guide can be pushed onto the foot region of the hook.

The foot area is the section of the hook that is directly attached to the profile. These are followed by the transition area. In the transition region, the hook is curved so that the angle between the second leg of the profile and the direction of adjoining the transition region End region is determined at least substantially by the curvature of the transition region. At this transition region joins the tapering, which continues at least substantially straight into the end.

The invention is based on the observation that the beating of pleated blinds fastened with prior art window clips is often due to the fact that the pleated blind guides can not be stretched sufficiently between the window clips because the pleated blind guide must be knotted at least at one end to the hook. By the tapered transition region of the hook fastening means can be pushed onto the hook of the window clip according to the invention and fixed thereto, which allow easy installation of the pleated blind under sufficient tension and possibly a retightening. This is especially true when the material for the hook is formed out of the second free leg. Then, the hook has a corresponding recess, the width of which widens in the region from which the tapering area is formed in the direction of the approach of the hook steadily to a maximum width. This widening recess makes it possible to postpone a correspondingly larger fastening means from the end region over the curved transition region of the hook until it rests on the foot region.

Preferably, the fastening means for the pleat system guide is a roller with a recess, wherein the recess is pushed onto the foot region of the hook and rests with one of its longitudinal sides on the second free leg. Such a role makes it easy to stretch and fix a pleated blind.

The recess is preferably cylindrical and concentric with the axis of the roller. In particular, at least the ends facing away from the second leg be chamfered to the role of the recess. As a result, the end region and / or the tapering region of the hook can abut at least piecewise flat on the end face of the roller. Surprisingly, the role is determined by the chamfer on the hook, ie it does not rotate on the hook and therefore can absorb tensile forces of Plisseeanalagenführung. This worked best with plastic wheels. An additional definition of the role by adhesive is unnecessary.

An additional clamping action defining the fastener is achieved when the width of the fastener, e.g. the o.g. Roll is between 0.1mm to 0.4mm larger than the gap between the end portion of the hook and the second leg.

Preferably, the roller in its lateral surface has an annular groove with a slot-shaped end region. In the simplest case, the end region is a slot with parallel side walls. This allows the pleat system guide to be pulled over the roller for tensioning so that it clamps into the end region of the annular groove during clamping. Preferably, the width of the end region tapers, e.g. tiered like a funnel. As a result, different pleat system guides can be clamped with a roller and the clamping effect increases with increasing tension on the pleat system guide. For a particularly good handling and high holding forces of the outer diameter of the pleat system guide and the width of the slot-shaped end portion are matched.

When the width of the annular groove initially tapers like a funnel with decreasing distance from the roller axis and then merges into the end region, the pleat system guide first slides over the surfaces of the funnel-like region during clamping and is automatically pulled into the end region when it reaches the predetermined tension and clamped there , The surfaces of the richterartigen area thus act as centering for the pleated blind.

The roller may have at least one longitudinal slot parallel to the roller axis, by means of which the free end of the pleat system guide can be fixed. Of course, the longitudinal slot can also be combined with the annular groove, which results in a particularly good guidance and fixation of the pleat system guide on the roll.

The window clip can be molded from both a plastic and metal.

If the fastener omitted or removed, then as usual, a curtain rod can be plugged onto the window clip. If the curtain rod has a recess adapted to the tapered transition region, the curtain rod can be clamped with the recess on the tapered transition region.

The FIG. 15 shows a front view of a window 200 with a Plisseeanalage 300. The FIGS. 16 and 17 show a side view of the window 200 and detail B of the side view. On two pleat system guides 320, a pleated blind 310 is displaceable as a sunshade and / or privacy screen ( Fig. 15, 16 ). The window 200 has a frame 210 onto which a total of four prior art window clips 100 are slid. Between each two vertically stacked window clips 100, a thin rope is attached as a pleated installation guide 320 of the pleated installation 300. For this purpose, the two ends of the pleat system guides 320 are each knotted into an eyelet, which can slip on the foot region 163 of the hook 160, for example, by wind action or when opening the window 200 (see detail B). This is especially true when it has not been possible to apply a sufficient tension on the pleat system guide 320 when knotting the eyelets. Another disadvantage of the prior art window clip 100 is that the pleat plant guide 320 in FIG unfavorable case, as shown in detail B, may have a fairly large distance from the window frame 210. This reduces the distance between the window handle 220 and the pleated blind 310, thereby reducing the maximum pleat width of the pleated blind 310.

The window clip 1 according to the invention is in the FIGS. 1 to 4 in an isometric representation ( Fig. 1 ), a front view ( Fig. 2 ), a side view ( Fig. 3 ) and a supervision. The window clip 1 has the shape of a substantially U-shaped profile with a transverse leg 30 on which a first free leg 10 and a second free leg 50 are formed (see. Fig. 1 u. 3). While the second free leg 50 forms a right angle with the transverse leg 30 (see. Fig. 3 ), the angle between the first free leg 10 and the transverse leg 30 is an acute angle (<90 °), ie, the first free leg 10 is slightly tilted in the direction of the second free leg 50. The end portion 12 of the first free leg 10 is curved in the direction of the second free leg 50. As a result, the window clip 1 can be easily pushed onto an end portion of a window frame (not shown). Then, the window clip 1 is flush with the inner surface 52 of the free leg 50 on the inside of the window frame, whereas the first free leg 10 rests with the curvature of its end portion 12 on the other side of the window frame.

From the second free leg 50, a hook 60 is formed out (see. Fig. 1 ). For this purpose, the contour of the hook can be punched out of the free leg 50 and then bent to the hook 60.

Correspondingly, the hook 60, starting from the second free leg 50, has a foot region 63 pointing away from it. The foot region 63 is adjoined by a bent transitional region 62, which merges into a tapering region 64 extending at least approximately parallel to the second free leg 50. The tapering region 64 is followed by an end region 61 with a here rounded top 65. The rounded tip 65 of the end portion 61 of the hook 60 is parallel to the plane defined by the transverse leg 30. The width b _{3 of} the hook 60 is constant in its foot region 63 and in the transition region 62. In the tapering region 64, the width is reduced steadily to a width b ₁ (cf. Fig. 2 ). In the end region 61, the width of the hook 60 remains constant up to the tip 65. This reduction in width in the tapering region 62 makes it possible for a fastener subsequently seated without play on the foot region 63 of the hook to be pushed onto the hook 60. This is the example of a role 80 in the FIGS. 5 to 8 represented ( Fig. 5 and 7 : isometric views, Fig. 6 : Side view, Fig. 8 : At sight).

The in the FIGS. 9 to 12 shown roller 80 has an axial cylindrical recess 85 with the diameter b ₈ , with which it sits on the foot portion 63 of the hook 60, that one of the two end faces 87 rests flat on the front of the second free leg 50 and the other end face 88 of Roller 80 abuts the end portion 61 of the hook 60 with its inside (see. Fig. 5, 6 With fig 9 to 12 ). The inner diameter b _{8 of} the roller, ie the diameter b _{8 of} the recess 85 and the width b ₃ are tuned to each other as a function of the thickness of the hook 60, that the roller 80 on the foot portion 63 has no radial play and the roller 80 in the center sitting on the foot 63. Because of the small thickness of the hook, the inner diameter b ₈ in this sense corresponds approximately to the width b ₃ . The difference between the inner diameter b _{8 and} the outer diameter b ₉ is smaller than the gap defined by the end region 61 and the second free leg 50. Because of the end region 61, which is tapered in comparison to the foot region 63, the roller can thus be pushed onto the end region 61 without difficulty. If the roller 80 is pushed over the tapering region 64 and the transition region 62 onto the foot region, then this is only possible because a part of the roller 80 dips into the widened region 56 recess 55. The width b _{3 of} the transition region 62 and of the foot region 63, the gap width between the end region 61 and the second free leg 50 as well as the inner diameter b ₈ and the outer diameter b ₉ are coordinated so that when pushing the roller 80 on the tapering portion 64 and the transition region 62 on the foot portion 63 of the edge 97 of the roller 80 slides over the edge of the widened portion 56 of the recess 50 the hook slightly springs up. The widened portion 56 of the recess 55 is the portion from which the foot portion 63 and the transition portion 62 have been formed. Thus, the distance of the edges of the widened region 56 of the recess 55 corresponds to the width b _{3 of} the foot region 63.

Because the recess 85 is chamfered (see. Fig. 9 : Chamfer 86), the end portion 61 is flush with the end face 88, although the transition region 62 is not angled but arc-like. In this case, the end region 61 projects beyond the roller 80, ie it is longer than the outer radius b _{9 of} the roller 80. As a result, a pleat system guide can easily be placed on the lateral surface of the roller 80 because it is sufficient to lay it loosely over the hook 60 and then pull tight over the roller 80. The end region 61 of the hook 60 is thus a threading aid for the pleat system guide and at the same time fixes the fastening means, ie the roller 80 in the example shown, against displacement on the foot region 63 of the hook 60.

The roller 80 has in its outer surface an annular groove 90 (see, eg Fig. 10,12 ). The annular groove 90 has two opposing centering surfaces 92 which attach directly to the corresponding outer edge 97 of the roller. As a result, a loosely inserted in the hook pleat system guide is centered on the center of the role of tightening. If the pleat system guide is stretched over the roller 80, it slips into a slot-shaped end region 95 of the annular groove 90. In this, the pleat system guide is clamped during clamping and thus fixed (not shown). Lateral slippage of the pleat guide is excluded, as well as problems in applying the necessary tension to the pleat system guide, because the end portion 95 is dimensioned such that the Plisseeanlageführung as long as on the centering slides until it acts a clamping force that is greater than the minimum necessary clamping force. Only then does the pleat system guide slide into the slot-shaped end region 95 and is clamped there. Of course, the tension can be further increased, but this must be overcome the correspondingly high clamping forces.

The in Fig. 13 shown window clip 1 and the in Fig. 14 shown window clip 1 are different from the window clip 1 in the FIGS. 1 to 4 only by the arrangement and the direction of the hook 60. Therefore, the same or similar parts are provided with the same reference numerals and the description of the FIGS. 1 to 8 applies analogously.

At the window clip in Fig. 13 the end portion of the hook 60 is disposed in a plane parallel to the second free leg 50, but its tip is different than in FIG Fig. 1 shown not opposite to the free end of the free leg 50, but with mounted window clip parallel to the window frame portion on which he sits. This allows the window clip, if it is laterally attached to a window frame a curtain rod support. Because the window clip can be plugged into any position of the window frame, partial curtains can also be fastened with the window clip.

At the window clip in Fig. 14 the end portion of the hook 60 is disposed in a plane parallel to the second free leg 50, but its tip is different than in FIG Fig. 1 shown in the transverse leg 30, but in the direction of the free end of the second free leg 50. Thus, an attachment plate for a window in gap between the hook 60 and the second free leg 50 is pushed and thus secured in front of the window. Typical attachment lenses are, for example, frosted glass attachments as privacy screens or colored decorative discs.
