Definitions

  • the invention relates to a roller shutter for storage openings in cabinet furniture, wherein a plurality of hinged roller shutter profiles are guided in lateral, U-shaped profile guide rails and wherein a weight compensation is used in the roller shutter drive, which prevents unwanted closing and opening of the roller shutter.
  • French patent application 78 09421 describes a generic roller shutter which can be used, for example, for closing a garage or a truck body.
  • the armor consists of individual armor elements which are connected to one another in an articulated manner. These armor elements are moved by a horizontal drive shaft on which a torsion spring is held.
  • the drive shaft and torsion spring are surrounded by a tubular cylinder, on the outer circumference of which longitudinally displaceable gear wheels are arranged.
  • These gearwheels engage in the cutouts formed in the individual armor elements and serve as a roller shutter drive when the door armor is rolled up or lowered.
  • This door armor is driven by the drive shaft via the gears, which at the same time guide the door armor during the various rolling movements.
  • the door armor is guided laterally in guide rails in which the end areas of the individual armor elements are guided during the movement processes.
  • the door arm's downward movement is supported by the torsion spring arranged on the drive shaft, which serves as a classic weight compensation.
  • the system is set up so that the torsion spring is tensioned when the door armor is closed. If the door armor is unlocked to open it, the torsion spring tends to expand from the tensioned state into the rest position and thereby sets the tubular cylinder with the gearwheels in a rotational movement acting in the opening direction.
  • the door armor is moved into the open position via the gears and their engagement in the cutouts of the individual armor elements, the action of the torsion spring being able to be supported by the operating personnel until the door armor is completely opened by slight pushing.
  • roller shutter system with its complex drive mechanism can be used primarily for closing large openings such as garage doors, motor vehicle bodies and the like. In the case of smaller tank sizes, such as those used for closing box furniture, this complex drive is uneconomical and is not accepted by the market.
  • the weight compensation is a one-piece, continuous rope, which is attached with its free ends to a roller shutter profile and is guided over at least two deflections in the manner of the pulley principle, that a compression spring is arranged between the deflections, which compared to the Rope taken off force absorbs a lot of movement force resiliently, and that the structure of rope, deflections and compression spring is guided at the top of the roller shutter.
  • the roller shutter according to the invention is a roller shutter system for furniture openings, wherein when the roller shutters are opened, they are not wound up but guided behind the rear wall of the cabinet. This means that no space is lost in the cabinet height.
  • the facial expressions for weight compensation have a double function according to the invention, i.e. with half-open roller shutters there is balance and, based on this, an increasing force is required to balance the weight for both closing and opening.
  • a continuous cable is used according to the invention based on the pulley principle via deflection pulleys.
  • the compression spring is mounted between the rope bottles and brings up a multiple of the force taken off the rope - according to the force-displacement equation.
  • the cable connection to the roller shutters is selected so that it is in the half-open or half-closed position at the height of the cable outlet, ie in the position with the lowest cable tension. In this position, the rope turns over, ie when the door is fully opened or closed, the rope tension increases to the maximum force.
  • the deflections are rotating rollers running in a housing.
  • This housing-roller combination is also in the present text as Rope bottle ".
  • the compression spring is articulated with its free ends to the facing end regions of the deflections.
  • the free rope ends are advantageously attached to the roller shutter profile, which is in the position with the lowest rope tension when the roller shutter is half open or half closed.
  • the guidance of the rope deflection-compression spring assembly is combined in a tubular guide element. With a special installation, this guide can also be arranged in an intermediate floor of the cabinet furniture.
  • one end of the rope is attached centrally to the roller shutter profile, while the other end of the rope is pulled down through the intermediate floor. This allows the tension of the rope to be changed, since the rope is arranged so that it can be reached from inside the cabinet.
  • roller shutter 1 shows the roller shutter 1 in the cabinet unit 2, the guide grooves 211, 221 for the lateral ends of the roller shutter profiles being embedded in the side walls 21, 22.
  • the tubular guide element 3 is arranged above the roller shutter profiles and is closed at its free ends by a cover 31, 32.
  • the cover 31, 32 each has an opening 311, 321 through which a rope 7 runs.
  • the cover 31 shown on one side in FIG. 2 with the opening 311 also closes the other free end of the tubular guide element 3 with the cover 32 in mirror image.
  • the rope 7 is articulated on the one hand at the left free end of the roller shutter rod 11. After a deflection of 90 °, it runs through the opening 311 of the cover 31 into the interior of the tubular guide element 3. Within this guide element 3, two deflections 4, 5 are mounted, between which a compression spring 6 is arranged. Between the deflections 4, 5, the cable 7 runs in a roller guide according to the block and tackle principle, as described in detail for FIG. 3. The cable 7 then runs out of the tubular guide element 3 through the opening 321 of the cover 32, is again deflected by 90 ° and fixed at the other free end of the roller shutter rod 11.
  • the roller shutter rod 11 denotes the center of the roller shutter, in which it is in the half-opening position with the lowest rope tension.
  • FIG. 3 shows an enlarged detail from the upper left area of FIG. 1.
  • the guide profile 27 for the roller shutter 1 is embedded in the cabinet side wall 21.
  • the cover 31 with the opening 311 for the cable 7 is firmly inserted by the mechanical screw element 312.
  • the deflection 4 is arranged, on which a roller 41 for the cable deflection is attached.
  • the end 61 of the compression spring 6 is arranged.
  • the cable 7 runs in a circumferential groove of the roller 41 according to the surface tension principle.
  • FIG. 4 shows a further possibility of using the block and tackle principle in such cabinet shutters.
  • This is the assembly of clamping levers on the intermediate floor of a piece of cupboard furniture.
  • the movable clamping lever 8, in which the tension spring 81 is suspended, is arranged on the intermediate floor 28 of the cabinet 2.
  • the tension spring 81 is connected at its other free end to a fixed mounting element 82.
  • the tension spring 81 can be adjusted in force by changing the mountings.
  • the articulated clamping lever 84 is arranged, via which the clamping lever 8 can exert an articulated connection in the form of a lifting movement.
  • the rope 7 runs here over a movable deflection roller 86 at the other free end 85 of the tensioning lever 8 and over a fixed deflection roller 87 in the region of the middle position.
  • the cable 7 can then be guided through the intermediate floor in a middle cable system, the cable tension being able to be varied from the interior.
  • roller shutter 1 shows a solution in which the roller shutter 1 is guided in a screw 12 or a curved rail during the opening process.
  • the rope 7 is in this case tied to the lower edge of the roller shutter 1, since the rope handling - as described for FIG. 2 - is not necessary here.
  • the roller shutter 1 does not tip backwards when opened, but is guided in the screw 12 until it is fully opened.
