Abstract

The clamping holder (1) has two interfitting clamping yokes (3,4) each with a clamping cheek (6, 10) and guide cheek (19, 20). The front yoke (3) fits round the guide cheek of the rear yoke and in the fitted state its downwardly angled clamping cheek bears at the front against the window frame (2). A screw threaded rod (9) at the front of the guide cheek engages in a threaded bore (11) in the guide cheek (20) of the rear yoke to connect the two yokes movably together which can then be spaced apart and tightened up by turning the rod to secure the two clamping cheeks against the frame in the fitted state. A commercially available holder for a roller blind can be fitted on the front yoke.

Description

The invention relates to a clamp for attaching sun or protective glasses to Holmen of windows, doors or the like with each other and mutually displaceable clamps.

In house construction, plastic windows and doors are increasingly being used today. These plastic windows and doors in addition to many advantages have the disadvantage that you can attach to them brackets for blinds, blinds or the like by screwing into the frame or the fold, as it is relatively easily possible in Holzfenstem and wooden doors, if it is in the case of rental housing is often not allowed. Similar to plastic windows also applies to aluminum windows, which are often used for office buildings.

From the EP 0 358 742 B1 For example, a clamp holder for sun or protection devices on spars of windows, doors or the like is known which has two mutually displaceable clamping flanges. The front clamping flange is fixed and has a threaded eye with threaded rod. The threaded rod is rotatably mounted on the gripping behind the spar flange and so on the first flange and away from him. The two clamping flanges are not guided into each other and therefore only fixed by the threaded rod. Similar to the EP 0 358 742 B1 is the one in the DE 296 08 909-U1 disclosed embodiment of a clamping holder.

In the DE 100 47 633-A1 is a clamp for sun and / or privacy devices presented with a bracket for engaging behind a window frame and a counter-leg to hold the sun and / or privacy devices. The counter-leg consists of a receiving part and a clamping part, wherein the clamping part has a stationary rotatably mounted threaded spindle, the outer peripheral portion exposed to the bottom to engage introduced into the upper part of the bracket thread depths and so to adjust the bracket against the opposite leg. Bracket and counter-legs are made of plastic.

A clamp holder made of metal, which is composed of successive angles, is known from German Utility Model 87 05 267.9. The angles are mutually displaceable by means of a set screw.

From the EP 0 866 205 B1 holders are still known, which are clamped by spring force on the spar.

A disadvantage of many known brackets is that they only allow the installation of a Venetian blind or roll type. As a rule, the brackets of aluminum blinds differ from those for plastic blinds and these in turn from holders for wooden blinds. The user therefore has to acquire new attachments and new clamps each time he changes the type of blind, or DIY stores need to stock a variety of different fixtures or attachments.

It is an object of the invention, a clamp holder according to claim 1.

• der hintere Klemmbügel im hinteren Bereich, vorzugsweise am Ende, seiner Führungswange eine nach unten abgewinkelte Klemmwange, die im montierten Zustand hinten am Holm anliegt und im vorderen Bereich, vorzugsweise am Anfang, seiner Führungswange eine Aufnahme mit Gewindebohrung aufweist, und

die beiden Klemmbügel über eine durch den Widerhalt und durch die Aufnahme mit Gewindebohrung geführte Gewindestange gegeneinander verschiebbar verbunden und mittels Drehen der Gewindestange beabstandbar und aufeinander zuführbar sind, um im montierten Zustand die beiden Klemmwangen gegen den Holm festzulegen.The object is achieved by a clamping bracket for attaching sun or protection devices on Holmen of windows, doors or the like, wherein the clamp has two nested clamps each with clamping cheek and guide cheek,

• the front clamp in the region of its front guide cheek slidably includes the guide cheek of the rear clamp on both sides in a guide rail, and an angled down in the rear of the front guide cheek clamping cheek which rests in the assembled state on the front of the spar and in the front region, preferably at the beginning, having a support for performing a threaded rod, and
• the rear clamp in the rear, preferably at the end, its guide cheek down angled clamping cheek, which rests in the assembled state behind the spar and in the front region, preferably at the beginning, its guide cheek has a receptacle with threaded hole, and

the two clamping brackets are slidably connected to one another via a threaded rod guided through the support and through the receptacle with threaded bore and can be spaced and fed to each other by turning the threaded rod in order to fix the two clamping cheeks against the rail in the mounted state.

Preferred embodiments are subject of the dependent claims or described below.

The clamping cheek of the front clamping bracket is viewed from the front at the level of at least half the length of the guide cheek, preferably at least 3/4 or 5/6 arranged. Preferably, an end piece of the guide cheek lies on the upper side of the spar, wherein the end piece preferably has a bearing surface of 2 to 8 mm with the upper side of the spar.

Preferably, the guide rail is formed in the front clamp by two parallel spaced, open towards the center grooves. The grooves can in this case extend over the entire length of the guide cheek of the front clamp or extend only over a portion, but in particular over more than 50% of the length of the guide cheek. Preferably, the rear guide rail is 0.5 to 5 cm, preferably 0.5 to 3 cm long. When tightening (screwing in) the threaded rod, the rear clamp is guided in the guide rail of the front clamp. By the two-sided embracing the rear guide cheek along its longitudinal edges through the grooves an all-round stabilization of the clamp is created relative to each other.

In a preferred embodiment, the front clamp is substantially entirely of plastic and the rear clamp is substantially entirely of metal.

According to a further preferred embodiment, the front clamping strap on a guide cheek with hollow body, wherein in the hollow body, the guide cheek of the rear clamping bracket is added. In this case, the hollow body rounded up and flat below, like a half-cylinder, or be box-shaped. The upper side of the hollow body is preferably designed as a round roof and extends over approximately the entire length of the guide cheek of the front clamping bracket. The screw head of the threaded rod is preferably covered by a blind cap. This gives the clamp a pleasing appearance that completely obscures the mechanics of the clamp movement.

Preferably, the clamping cheek of the front clamping strap on two parallel slot strips with associated parallel slots, wherein the slot strips extend along the side edges of the clamping cheek and slidable in the slot strips Fixing members can be fixed by means of guided through the slots screws. The slit strips are located on the side facing the spar. In this lock nuts are einlaßbar. The slit strips can be recessed against the full thickness of the clamp.

Preferably, the threaded holes of the locknuts are arranged eccentrically to their key surfaces so that, depending on the orientation, i. both outside, both inside or one outside and one inside, different distances of the threaded holes result.

Furthermore, it is preferable to provide the side of the clamping cheeks or the upper bearing region, which is located to the side of the spar, in regions with anti-slip material. The anti-slip material is preferably rubbery, and more preferably self-adhesive.

By means of the lock nuts commercially available holders for aluminum, wood or plastic blinds can be attached to the clamp. Likewise, holders for curtain rods of coffee house curtains or other holders for sun or Blickschutzeinrichtungen or the like can be attached.

The terms "front" and "rear" apply in each case from the perspective of a viewer in front of the mounting side of the window and only for explanation. In the foreground are each the objects closer to the viewer and the farther the more distant. The terms "top" and "bottom" refer to a clamp mounted on the top rail of a window. "Rear" and "front" or "top" and "bottom" are only relative to each other and not absolute.

The clamping bracket according to the invention consists of at least 2 parts. Preferably, a front plastic clamp, for example polyethylene, polypropylene, polyester or polyamide or ABS, together with the corresponding fiber-reinforced plastics, and a rear clamp of threaded metal. The clamping bracket according to the invention can be mounted on / in each tilt window, whether wood, aluminum or plastic.

The metal bracket runs in a guide in the plastic part, so that by tightening the threaded rod, the metal part on the front clamp is adjustable. The screw head protrudes here from the opening in the abutment and is in this rotatably guided. The head of the screw is easily accessible at the front and can be turned using conventional tools such as screwdrivers or keys. This allows installation in largely closed windows, without the fitter during the installation over a longer period of outdoor exposure must be exposed, as required for clamps that are screwed from behind.

If desired - for optical reasons, for example - the screw head can be concealed by placing an aperture cap on the front of the front guide cheek. For this purpose, it is advantageous if appropriate Einklippverankerungen are provided on the abutment for mooring the visor.

The clamping bracket according to the invention has the advantage that it is easy to handle, since it can be placed without effort on the spar of a window or door and the clamping screw can be tightened as part of the threaded rod with any conventional screwdriver and no special tool for attachment is necessary. The two-part construction using plastic is also cheaper to manufacture than conventional clamp brackets.

The clamping bracket according to the invention is also very stable, since the rear clamping cheek has its full thickness over the entire length and width and is not weakened by recesses or cuts. The design allows mounting on windows with different widths Holmen, since the distance between the front and rear clamping cheek is adjustable. Furthermore, contributes to the stability that the threaded rod is preferably made of metal.

Preferably, the two guide cheeks are offset plane-parallel and more preferably the rear guide cheek is guided directly over or even on the front guide cheek. The two clamping cheeks are also preferably arranged offset plane-parallel and plane-parallel away from each other and to each other to be moved.

Fig. 1 to 5 show the structure of the clamp (1) and their mounting on a spar (2), such as the spar of a window or a door. The clamping bracket (1) has a front clamping bracket (3) with guide cheek (19) and clamping cheek (6), wherein the guide cheek (19) in the front region an upwardly angled abutment (7) with opening (8) for carrying out a set screw (9) and at the rear of a downwardly perpendicular angled clamping cheek (6) for application to the inside of the spar (2) carries and the guide cheek (19) continues in the form of a support surface (22) for the spar top (12).

From behind a rear clamping bracket (4) by means of its guide cheek (20) in the guide rail (5) of the front clamping bracket (3) is inserted. Through the opening (8) in the abutment (7) of the front guide rail (5) an adjusting screw (9) is guided with threaded rod which engages in the threaded hole (11) of the rear guide rail, so that by means of rotation and merging of the front clamping cheek (6 ) and the rear clamping cheek (10), the clamping bracket (1) can be tightened on the spar.

In the assembled state, the clamping cheeks (6, 10) are firm and slip-proof on the spar (2). The opening and closing of the window is not hindered by the clamp, since the clamp (10) has a low material thickness.

The clamping cheek (6) of the clamping bracket (3) is provided with two parallel slot strips with slots (13) which extend along the clamping cheek (6). The slots (13) are offset by a distance which is usual for the fastening means of holders (16). The screw holes of the various commercially available attachments (16 a, b, c, d) usually have no standardized distances or positions. In order to make the clamping bracket (1) for a variety of attachments (16) used, the slots (13) have a greater width than would be necessary for the mounting screws (21). The fastening screws (21) engage in suitable in the slot strips movably guided lock nuts (17). The threaded holes of the square locknuts (17) are arranged eccentrically to their key surfaces, so that their distance by aligning the locknuts (17), close to the threaded hole edge or threaded hole center, is changeable. Furthermore, the lock nuts (17) are displaceable relative to each other in the slot strips.

The lock nuts (17) are mounted against rotation in the opposite of the full thickness of the clamping cheek (6) recessed formed slot strips. The slit strips are groove-like depressions, in which the lock nuts (17), possibly with a certain play, are einlaßbar.

Preferably, the clamping bracket (1) is mounted by first the front clamping cheek (6) is applied to the spar (2) and by means of rotation of the adjusting screw (9), the rear clamping cheek (6) is brought to the spar (2).

Unlike in the FIGS. 1 to 4 the holder can also be attached to the underside of the guide cheek (19) of the front clamping bracket (3). As in Fig. 5 shown, a rotatably mounted two-leaf bracket (23) (in the figures partially covered by the front clamp (3)) projecting down the underside of the guide cheek (19) of the front clamp (3) provided with their downwardly projecting wing ends (24) is engageable by rotation with a U-profile-like support rail (27) of a blind (26). For this purpose, the wing ends (24) are first in Halteschienenrichtungsverlauf (28) aligned (Figure (a)) and subsequently - after the retaining rail (27) on the guide cheek (19) of the front clamping bracket (3) is brought - by moving the handle (25 ) brought in the upper area in engagement with the side walls of the retaining rail (27) by the handle (25) is rotated so far and thus the two-leaf bracket that the handle (25) on the outside of the support rail rests (Figure (b)) and the wing tips (24) are aligned perpendicular to the support track direction course (28).
