Description

  • The The invention relates to a clamping device for clamping the rolling arm a roller shutter, and a clamping arrangement with at least two such Clamping devices.
  • at buildings become windows, doors or gates by means of shutters closed, with guide rails guided Rolling armor by unwinding a shaft along the guide rail be lowered to, for example, a privacy screen or a Graduation for the windows, gates or doors bring about. Especially with gusty Winches and the use of plastic slats as elements of the Rollpanzers there are rattling noises from the residents of the building as disturbing be felt. It is known on the inner cheeks as U-profiles trained guide rails elastic coverings Provide the rattling noises reduce.
  • It Object of the present invention, a clamping device for Provide terminals of a rolling armor, with the rattling noises be reduced or prevented more efficiently.
  • These Task is solved with the features of claim 1 and 19, respectively.
  • advantageous Embodiments are the subject of the dependent claims.
  • at the clamping device according to claim 1 will the closing movement or a portion of the closing movement of the rolling arm of a Used to make a rail to rest on a roller shutter Side and / or end face to bring the rolling armor. Here, the closing movement of the Rollpanzers a driver with, with a deflector is connected and acts in such a way that the plant rail through the operation of the driver on the side and / or end face of the rolling arm to rest comes. By the concern of the system rail on the side and / or face of the Rollpanzers becomes the play of the Rollpanzers perpendicular to its Side and / or end face or the play of the rolling arm inside the lateral guide rails of the Rollpanzers, reduced, so that due to the reduced or eliminated rattling noises considerably muffled or even turned off completely. The support of the installation rail on the side surface is preferred over the support on the face, there the rattling noises essentially by lateral deflection of the rolling arm in the guide rail is caused. But also a frontal clamp or a Clamping on the edges of the rolling armor (corresponds to clamping on side and side) Face) can for certain geometries of the roller shutter be favorable. The following will be of side surface clamping spoken, but this also applies accordingly for the Stirnflächenklemmung.
  • All Particularly advantageous is the driver for actuating the deflection device at least partially formed by the contact rail, so that the Mechanical construction of the clamping device considerably simplified and thus cheaper is. In an embodiment, the driver is at least partially on the rolling armor arranged, in particular arranged on a lamella of the rolling armor.
  • is the driver with respect to such arranged the rolling arm, that this particular with an end member immediately before the end position of an end member of the rolling armor engages, so the rolling armor until just before the Shut down of the roller shutter unhindered or almost unhindered by the contact rail be lowered or raised. This can be realized advantageously, by a projecting element at the bottom or bottom End area of the contact rail or the guide rail for the roller armor is arranged so that an actuation the clamping device actually only in the final phase of the closing movement of the shutter. In a Rollpanzer with view slots Advantageously, the operation the deflector when the lower end of the rolling armor approaching its lowest position, So the viewing slots are still open.
  • Advantageous If clamping device is e.g. by means of a spring-elastic element designed so that only the gradual closing of View slits or the gradual approaching to the full closed position of the rolling shell to an end position of the clamping device or the Anlageschiene leads, in the clamping force is the strongest is. Before the final closed position the rolling stock is the contact force of the system rail at the Side surface of the Rolling armored such that further lowering of the rolling armor e.g. to close ensures the viewing slots is.
  • The Deflection device advantageously has at least one fastening element on, with the deflection of a window frame or the guide rail for the Rolling armor is attachable. This allows the clamping device without big ones Retrofit installation work on the existing roller shutter system. Especially if the fastener a groove or a clamp for attachment the deflection device on a leg portion of the guide rail has, the clamping device without great technical knowledge be retrofitted to the existing shutter system.
  • All Particularly advantageously, the clamping device has at least two Deflection on which the support rail adjustable is stored, the plant rail advantageously offset by is mounted to each other arranged deflection. This reduces the mechanical requirement of the stability of the deflection due to significantly reducing or avoiding leverage.
  • Advantageous the provision is made the contact rail by at least one, the deflecting associated, resilient element, so when booting up the rolling armor an automatic reset the rail is done, i. a release of the clamping of the rolling armor through the rail during of opening of the shutter.
  • All Particularly advantageously, the clamping device has at least one Eccentric or a spreader disc, with the example of the linear lowering movement of the rolling arm in a pivoting movement of the Anlageschiene implemented in the direction of side surface of the rolling armor becomes. This leaves of course also reach by a corresponding pivot lever control. at Use of at least two spaced-apart deflection devices is advantageous a movement according to the pivoting of a Parallelogram executed.
  • Advantageous is the contact rail itself part of the guide rail for the rolling armor, so that the clamping device is more compact and manufacturing technology cost savings in the new production of a roller shutter system result. For example, the contact rail acts before the Deflecting the rail to bring the clamping as pure Guide surface opposite the Side surface of the Rollpanzers, before then in the final position of the Rollpanzers (Sichtschlitze possibly still open) the plant rail is brought to the plant or the game of rolling stock in the part through the track rail formed guide rail is reduced.
  • In advantageous embodiment leads the deflection device a pivoting movement about a horizontal axis out, so that the vertical adjustment movement of the rolling armor up simple way in a pivoting about the horizontal axis is made possible. In an alternative embodiment, the deflection device sets the actuating movement in a pivoting movement about a vertically extending pivot axis around. In this case, the contact rail comes, for example by a pure pivoting movement on the side and / or face of the rolling armor to concern. A vertical pivoting can be For example, achieve by a wave (for example, with angle as Driver at the lower end of the shaft) is guided in at least one groove, which represents a partial spiral of a helix. By depressing the Shaft by means of the driver leads the shaft then a combined lowering / pivoting movement. The on the shaft arranged support rail is carried along.
  • is the contact surface the rail at least partially provided with a sound-absorbing coating, so Already at low clamping force an effective reduction or prevention of rattling noises reached.
  • Based Figures become embodiments closer to the invention explained. Show it:
  • 1 a partial perspective view of a rolling arm in a guide rail with the associated clamping device,
  • 2A a partial side view partially in cross section with open clamping position,
  • 2 B the view of 2A with closed clamping position,
  • 2C the representation of 2A with continuous vertical profile,
  • 3A and B is a top view in cross-section with the clamps open and in the clamped position, and FIG
  • 4 a further embodiment of the invention in cross-sectional view.
  • 1 shows a partial perspective view of a shutter with a clamping device for clamping the lowered shutter to prevent rattling noises. Shown in sectional view, the side ends of three lamellae 4 , which is part of a roller shutter 2 are. The lateral ends of the slats 4 run in a guide rail 6 , wherein in each case a guide rail 6 is arranged at the opposite ends, so that the rolling armor 2 when lowering and pulling up inside the guide rail 6 (Opposite not shown) is performed.
  • On the outside profile leg 8th the guide rail 6 are two deflection mechanisms 10 attached to a vertical profile 30 wear. Each of the deflection mechanisms 10 has a slot 12 on, when attaching the deflection mechanism 10 on the outside profile leg 8th guided over this and there by means of screws 14 is attached. The placement of the deflection mechanism 10 on the profile leg is eg in the plan views of 3A and 3B to recognize more clearly. In the main body of the deflection mechanism 10 is a wave 20 stored, which is an eccentric disc 16 wears eccentrically. That is, the shaft is eccentric on the eccentric disc 16 arranged. Parallel but axially offset to the shaft 20 is on the other side of the eccentric disc 16 a holding pin 18 protruding into a hole 36 on the vertical profile 30 is inserted (see 3A and 3B ). The two deflection mechanisms 10 are spaced apart in vertical direction from each other on the profile leg 8th arranged so that by means of the likewise vertically spaced holes 36 the vertical profile 30 vertically aligned or parallel to the guide rail 6 is held. Of course, more than two deflection mechanisms 10 be provided per side of the shutter, for example, three deflection mechanisms wherein the number of deflection mechanisms on the height of the shutter depends. Both the retaining pin and the shaft 20 have at their outer ends threaded portions, so that by means of in 3A and 3B nuts shown the eccentric disc 16 on the main body of the deflection mechanism 10 or the vertical profile 30 on the retaining pin 18 is fastened.
  • On the eccentric disc 16 a spring acts 22 by means of a screw 24 on the main body of the deflection mechanism 10 is fixed. The feather 22 acts on the eccentric disc 16 that the retaining pin 18 with used vertical profile 30 is pivoted to its highest position. As long as no additional weight (see below) on the vertical profile 30 acts, lift the springs 22 the deflection mechanisms 10 the vertical profile 30 in an upper position. Here, the spring force is dimensioned such that in each case the unloaded vertical profile 30 is raised.
  • The vertical profile 30 is formed of a U-profile, with the side leg removed at the lower end and the bottom plate of the U-profile is angled at right angles, so that this section is an angle 32 formed. The angle 32 protrudes laterally on the outer profile leg 8th over and (seen in side view) in the guide groove of the guide rail 6 into - compare 2A , 2A shows the end plate 4 ' before this has reached the bottom point and before this on the angle 32 comes to the plant. 2 B shows the position of the rolling armor 2 in which the end plate 4 ' on the angle 32 rests and has reached its lower end position on the roller shutter. On the last section of the way between the resting of the end lamella 4 ' on the top of the angle 32 until reaching the lower end position of the Endlamelle 4 ' in the roller shutter is the angle 32 pressed down by the weight of the rolling arm, so that the angle 32 the vertical profile 30 in the last section of this movement of the Rollpanzers carries. Due to the storage of the vertical profile 30 on the eccentric disc 16 leads the depression of the angle 32 to a pivoting movement of the eccentric disc 16 and thus to a lowering and lateral movement of the vertical profile 30 , It moves the outer surface of the rolling arm 2 opposite inner surface of the vertical profile 30 towards the outer surface of the rolling armor and comes with increasing lowering of the rolling arm on the outside to rest.
  • How the comparison of 2A with the 2 B shows, reduces the concern of the vertical profile 30 on the outer surface of the rolling armor, the play of the rolling arm inside the guide rail 6 by lateral clamping. The in the final position of 2 B shown rolling armor is between vertical profile 30 and rear profile leg of the guide rail 6 clamped that the game is reduced and therefore no rattling noises can occur. To support the damping or clamping at uneven surface of the rolling arm or uneven leadership of the guide rail 6 is the inner surface of the vertical profile 30 with a topping 34 Mistake. Not shown embodiment can also on the inside of the inner profile leg 8th at the rear of the rolling armor 2 comes to rest, also be provided with a sound-absorbing coating, for example, with a small thickness.
  • 2C shows the the 2A corresponding arrangement in which the vertical profile 30 is shown throughout. The 3A corresponds to the position 2A the clamping device, wherein the vertical profile 30 unloaded and thus in the top position. 3B equals to 2 B in which the vertical profile 30 through the end plate 4 ' was pulled into the lowest position, so a maximum clamping of the rolling arm between the rear profile leg and the vertical profile 30 was brought about.
  • 4 shows a second embodiment of the clamping device with a partial view in cross section. Same or equivalent elements are denoted by the same reference numerals as in FIGS 1 to 3B designated. Here is the clamping device in the guide rail 6 integrated, wherein the groove width of the guide rail 6 larger than conventional guide rails. Between rolling armor and outer profile leg 8th is advantageous here by the width of the outer profile leg 8th hides a vertical band 40 arranged using leaf springs 42 elastic on the outer profile leg 8th is stored. Here are at least two leaf springs 42 for storage of the vertical band 40 provided, are advantageous over the height of the shutter or the guide rail 6 equally spaced, several leaf springs 42 intended. Shown is the position of the rolling armor 2 before lying on the angle 32 , On further lowering of the end plate 4 ' this comes to rest on the angle 32 and leads this down with continued lowering movement.
  • The vertical band 40 gets through the angle 32 pulled down, leaving the leaf springs 42 be deflected. It comes similarly to the deflection by means of the eccentric disc 16 to a pivoting movement of the bearing point of the leaf springs 42 on the vertical band 40 so that the vertical band 40 during the downward movement laterally parallel to the guide rail 6 is offset. With increasing downward movement comes again the covering 34 on the vertical band 40 to rest on the side surface of the rolling arm and thus reduces the game between the rear profile leg and vertical band 40 ,
  • In an advantageous embodiment, the vertical band acts 40 even as a sound-deadening element, so that the flooring 34 can be omitted. Next advantageous is the vertical band 40 designed partially elastic, so that by means of an elastic deflection by means of the leaf springs and the elastic deformation of the vertical band a positive engagement on the side surface of the rolling arm over the entire height of the shutter is achieved.
  • It should be noted that in the illustrated embodiments, the provision of the vertical profile 30 or the vertical band 40 is favored in the upper position by the frictional engagement between the rolling arm and the vertical profile or vertical band. That is, by pulling up the rolling arm and thus lifting the slats 4 and 4 ' also become the vertical profile 30 or the vertical band 40 lifted and thus solved the clamping.
