Definitions

• the invention relates to a clamp for a support element of a privacy or sun protection device for windows or the like / with the features of the preamble of claim 1.
• a known clamping bracket of this type (DE-GM 87 05 267) contains, in addition to the spindle, a screw holding the two guide parts together by means of an elongated hole in one of the guide parts, which is necessary for absorbing the torque, which depends on the distance of the spindle from the line of action of the Clamping flanges attacking forces decreases and wants to separate the guide parts.
• the known device has the disadvantage that it is complex because of the need for the additional screw and the associated threaded hole and that the safety of the clamp is also dependent on the screwing-in state of this screw, but this can be unsafe if the screw is not accessible , for example when installing directly under a blanket.
• the invention is therefore based on the object of creating a clamp of this type which does not put these disadvantages on hold.
• the spindle holder of the second mounting part is expediently designed to be open in a U-shape on the side facing away from the clamping flange, as a result of which the manufacture and assembly are considerably simplified.
• a cap can be provided which is supported on the guide part of the second holding part and which can also have a holding and supporting function.
• the cap can be designed so that it holds the spindle and the spindle together despite the open design of the spindle holder, so that these parts cannot fall apart during use.
• it can receive and support the free end of the spindle in a bore, thereby supporting itself on the guide part of the second mounting part.
• the two rods forming the guide parts of the second holding part can extend approximately as far as the spindle. The cap is then supported on the ends of these rods, it also being possible to provide a laterally securing support between the rods and the cap.
• a tab forming the spindle mount of the first mounting part contains lateral guide incisions for the rods forming the guide part of the second mounting part. In most cases, however, this is not even necessary in the clamp holder according to the invention, since the forces and moments occurring between the two holder parts can be adequately transmitted through the spindle, the two spindle mounts and the cap.
• an upward-pointing hook approximately parallel to the clamping flange, can be arranged on the clamping flange of the first holding part on its side facing away from the other clamping flange, to which a support arm is assigned, which has a support flange bent at an angle to an arm part has, in the support flange a slot in the hook, an opening in the arm part for the passage of the hook and in the bend area a web behind the hook is provided.
• the interaction of the hook with the slot in the support flange and in the height-offset opening in the arm part which are each dimensioned to match the hook width, ensures precise alignment of the support arm.
• the clamp bracket consists of the first bracket part 1, the second bracket part 2, the spindle 3 and the cap 4.
• the front, first mounting part 1 comprises a clamping flange 5, the clamping side 6 of which faces the clamping flange 7 of the second mounting part 2 and is parallel to it. It also includes a guide part formed by the rods 8, which extends perpendicular to the plane of the clamping flange 5. From the space between the two rods 8, a tab 9 is formed as a spindle mount, which contains a threaded bore 10 for receiving the spindle. In the example shown, it lies in the same plane as the clamping flange 5 beyond the guide part 8. It should be arranged as little as possible from the clamping flange plane. A distance of 5 or 10 mm to the front should expediently not be exceeded.
• the second holding part 2 has the guide part 11 formed by 2 parallel rods perpendicular to the plane of the clamping flange 7, the transverse dimensions of which correspond to the guide part 8.
• the tab 12 is formed as a spindle mount, which contains a U-shaped cut-out 13 which cooperates with a TJm-catch groove 14 of the spindle 3 and rotates it, but keeps essentially immobile in the longitudinal direction.
• the cutout 13 and the circumferential groove 14 thus together form a longitudinal bearing.
• the tab 12 is slightly offset from the plane of the clamping flange 7 towards the first mounting part in order to provide sufficient space behind the tab 12 for receiving the end head 15 of the spindle 3.
• the spindle 3 contains in its front end a hexagonal bore 16 for receiving a key for the purpose of actuation.
• the side edges 17 of the tab 9 can form lateral guide cutouts for the rods 11 near the surface of the rods 8. In the exemplary embodiment shown, this is not provided because it is generally not required.
• the two holding parts can be easily assembled by first screwing the spindle 3 into the spindle mount 10 and then attaching the second holding part and hooking it into the spindle with its U-shaped bearing part 13 .
• the cap 4 according to FIGS. 3 and 4 is then pushed onto the rods 11 of the second holding part in the longitudinal direction. It has a lower surface 18 at its front end which slides under the ends of the rods 11. In addition, it (not shown) can contain areas that are supported on the top of the rods 11. It also includes the rods 11 laterally and thereby also offers lateral support. It contains a bore 19 for receiving the end of the spindle 3.
• the clamping flanges 5 and 7 are pressed apart from one another at a distance from the spindle 3 and the guide parts 8, 11, as a result of which a torque is produced in the region of the guide parts and the spindle, which the second holder part tends to raise at the rear.
• the second mounting part 2 with the spindle mount 13 is supported on the spindle 3 against this torque.
• the cap 4 provides support between the front spindle end and the front ends of the rods 11.
• a support arm 22 has an arm part 23 and a support flange 24.
• In the support flange 24 there is a slot 25 in the center, the width of which is slightly larger than the width of the hook root 21.
• the slot 25 and the opening 26 are separated by a crosspiece 27 which fits exactly behind the hook 20. If the support arm 22 is attached to the hook 20 according to FIG. 10, the support arm is therefore fixed in all loading directions. It can be used, for example, to hold a curtain rod or a cover that hides the roller blind when it is raised.
