Definitions

  • the invention relates to a safety device for a roller shutter or roller door composed of rods, which can be wound up and unwound from a shaft, in particular if its last rod is provided with at least one laterally extendable safety bolt.
  • the extended safety bolt is intended to prevent the closed roller shutter or the closed roller door from being opened without authorization from the outside by being pushed open.
  • at least one laterally extendable securing bolt is provided on the bottom bar, which cooperates with a spring, the pretension of which allows the bolt to extend from an intended bolt receptacle if a train directed against the spring pretension is omitted when the roller shutter or the roller door is closed.
  • This train is achieved by a cable connection between the uppermost and the securing bolt provided in the lowermost bar, taking advantage of the fact that the bars of a roller shutter are at a certain distance from one another during opening and closing, relative to the position of the bars with the shutters closed.
  • This difference is transmitted to the safety bolt by means of a pull rope running from one of the upper rods to the last, lowest rod.
  • the safety bolt is therefore pulled back over the pull cable and, when closed, in which the pull cable is relaxed due to the smaller distance between the rods, is extended laterally under spring tension so that it can engage in lateral receptacles. If the uppermost rod is now raised during an attempt to penetrate, the rods are removed from one another and the tension cable is tensioned, which leads to the safety bolt being pulled back, with the result that the roller shutter or the roller door can now be opened by pushing it from below.
  • the shaft advantageously has a locking mechanism, formed by a cam disc arranged on one side of the shaft and a safety finger that projects laterally and cooperates with it, provided on the uppermost rod near the shaft, and a frame-fixed one Locking lug which engages under the safety finger when the roller shutter is closed, the cam disc having a recess extending up to the shaft circumference and the top rod of the roller shutter being fastened to the shaft in such a way that its safety finger is guided into the recess of the cam disc when the roller shutter is pulled up and held there is.
  • a locking mechanism formed by a cam disc arranged on one side of the shaft and a safety finger that projects laterally and cooperates with it, provided on the uppermost rod near the shaft, and a frame-fixed one Locking lug which engages under the safety finger when the roller shutter is closed, the cam disc having a recess extending up to the shaft circumference and the top rod of the roller shutter being fastened to the shaft in such a way that its safety finger is guided into the recess
  • the shaft to which the uppermost rod is fastened is first moved in such a way that it is first pulled radially inward with respect to the shaft from the locking lug and slides on the curve towards the recess insert it so that the top bar rests on the surface of the shaft and the following bars can be wound up without interference.
  • Any stop that is provided on the masonry of the installation opening or on the frame of the window or door can be used as a locking lug against which the safety finger rests.
  • the safety finger is advantageously designed as a pin inserted into the uppermost of the bars of a roller shutter and projecting in the longitudinal direction of the bar.
  • the cam disc can be provided with means that brakes or stops the movement of the winding shaft with the cam disc attached to it at the point that is optimal for securing.
  • These means can be, for example, a permanent magnet, which is arranged in this position, when this optimal point is reached with the safety finger interacts, which then consists of a ferromagnetic material, advantageously a magnetic flat steel inserted into the uppermost rod is provided.
  • At least two flexible connections are provided for fastening the uppermost rod, the length of which is matched to the diameter of the shaft in such a way that when the roller shutter is wound up, the safety fingers are pulled into the recess in the cam disc.
  • the wrap angle that the connections form when winding on the shaft is chosen so that the winding length corresponds to the angle taken by the curve of the cam. This length adjustment ensures that when opening the safety finger comes straight into the position under the locking lug, and just inserted into the recess of the cam disc so that the top bar comes to rest on the surface of the shaft.
  • band springs are also advantageously used as connections by means of which the uppermost of the rods is fastened to the winding shaft. The use of a stainless steel ensures a long service life of such ribbon springs.
  • a stop plate is advantageously provided as a locking lug in the area of the bearing of the shaft associated with the safety finger, which is preferably arranged to be adjustable in height.
  • the range of the height adjustment of the stop plate is at least half a width of a rod of the roller shutter or the roller door.
  • the cutting can, however, be carried out in a simple manner from the front, for example with sheet metal shears, so that lateral access is not important.
  • roller shutter lock designed in this way secures roller shutters or roller doors, even if they do not have an additional locking mechanism with side-acting locking bolts.
  • safety bolts or swiveling levers, angles or the like
  • these safety devices are supported in their effectiveness by the described safety device in such a way that they can be outwitted.
  • the cam disc is advantageously provided with a stub-like approach, which is preferably inserted in a form-fitting manner in the shaft of the shutter or roller door designed as a hollow shaft to prevent rotation.
  • This approach also allows an adjustment of the cam disc in the direction of the axis of the shaft, it being understood that after insertion and, if necessary, adjustment, the approach inserted into the shaft is fixed, for example by means of a screw.
  • FIGS. 1 and 2 show sectional and broken-away views of the closed roller shutter 1, which, with its rods 2 joined together, closes the free opening of a window (or a door).
  • the roller shutter surface formed by joined rods 2 can be wound onto the shaft 7 by means of a drive (not shown by hand or electrically), the edge parts of the rods 2 sliding into the lateral guides 5, which are usually plastered into the masonry and which have longitudinal sealing strips 5.1, which suppress rattling when the roller shutter swings.
  • the shaft 7 is rotated by the drive, the shaft ends being rotatably mounted with the bearing journal 8 in a bearing box 10, which is usually plastered in and which is closed with a cover 11.
  • the uppermost rod 2.1 is connected to the shaft 7 via a band spring 9, which is fastened to it, for example, with a clip 9.1, so that this first rod 2.1 and with it the following rods 2 are wound onto the shaft 7 when the roller shutter is opened .
  • a band spring 9 which is fastened to it, for example, with a clip 9.1
  • this first rod 2.1 and with it the following rods 2 are wound onto the shaft 7 when the roller shutter is opened .
  • at least the rods 2 are provided with end plugs which are received by the grooves in the lateral guide profiles 5.
  • This winding can now also be achieved by pushing up the bottom bar, which is designed as a sealing strip 2.2.
  • a is in the bottom bar Safety insert 14 used, which has a locking bolt 15 which can be moved transversely to the direction of movement of the roller shutter.
  • This safety bolt 15 is mounted in a guide which runs in the longitudinal direction of the end strip 2.2, and it is provided with a compression spring 16 which presses the bolt into a recess 6.1 provided in the central web 6 of the lateral guide profiles 5 when the roller shutter 1 is closed, this prevents the possibility of opening the roller shutter 1 by pushing it up.
  • the securing bolt 15 is connected to a cable 17, which is guided over some of the rods 2, the end plugs of some rods as end plugs 3 with molded cable pull guides 4 through which the cable of the Cable 17 is guided, are formed.
  • the bars 2 are raised in such a way that their distance increases, especially if the bars 2 (have ventilation slots (not shown)).
  • This increase in the distance determines the length of the cable pull 17 and thus also the number of rods which are provided with the end plugs 3 having a cable pull guide 4. If the roller shutter is opened, this increase in distance causes a pull on the cable 17, the free end of which is fixed in one of the bars 2, for example with a covering sleeve 17.1. This train is transferred to the safety pin 15, which is withdrawn so that the roller shutter 1 is released.
  • the number of rods 2 to be used is determined by the cable length required to retract the safety bolt 15 and the increase in the distance between two adjacent rods 2.
  • the cover 11 of the bearing box 10 which has an opening for the shaft 7, is provided with a recess 13 which opens towards the lateral guide profile 5 and through which a transversely protruding safety finger 22 arranged on the top bar 2.1 can pass when the roller shutter ( almost) is fully processed.
  • This safety finger 22 is designed such that it slides onto a cam 21 arranged on the shaft 7 with the curve 21.1 rising monotonously in the closing direction and is pressed by it under a stop plate 23 as a locking lug. This effectively prevents the upper rods 2 from being pushed up with the aim of disengaging the securing bolt or bolts.
  • FIG. 3 shows an illustration of the end of the shaft 7, with the bearing journal 8 ′ being provided on the outer wall of the bearing box 10, onto which a shaft piece 7.1, which receives the end of the shaft 7 in a form-fitting manner, is rotatably fitted.
  • the side guide profile 5 is connected to the inlet 10.1 of the storage box, an insert 10.2 ensuring the sliding transition of the bars of the roller shutter 1.
  • the rods 2 of the roller shutter 1 are fastened to the shaft 7 with the fastening band spring 9, so that they are wound up when the shaft 7 is rotated.
  • the cam 21, which secures the locking pin 22 used in the uppermost rod 2.1 in the closed state against evasion to the shaft axis, is placed here by means of a sleeve 7.2 on the shaft 7 with positive locking, so that the cam 21 around the polygon of the Shaft 7 given angles can be rotated on the shaft 7, which facilitates the adjustment.
  • the cam disk 21 shown here has a sickle-like finger 21.1, which, in the region of the large one Arranged diameter, the curve increases monotonically in the closing direction, leaving space under this sickle-like finger, for example for the locking pin 22 in the case of tight winding.
  • the stop plate is formed here by a protruding leg 26 of an insert 25 which is inserted into the storage box 11 or connected to the box cover at the construction site so that it can be cut to length according to the local conditions so that in cooperation with the Locking pin 22 the desired locking position required for this design of the roller shutter 1 is reached.
  • This insert 25 like the adjustable stop plate 23 (FIGS. 1, 2), permits readjustment if this should become necessary in the course of time.
  • FIGS. 4 show, in the manner of a glass section, the successive phases of winding on the basis of the sequence of four selected positions.
  • 4a shows the closed position of the unwound roller shutter.
  • the bars 2 have run into the side guide profiles 5, the uppermost of the bars 2.1 is before entering this profile.
  • the safety finger 22 is in a position immediately below the stop plate 23, which can be adjusted with the aid of the height adjustability provided by the fastening means 24 so that the safety finger 22 abuts directly on the lower edge of the stop plate 23 without being pressed against it.
  • the attached lid 11 of the bearing box 10 has a recess for the passage of the shaft 7, on which the rods 2 of the roller shutter 1 are wound; Furthermore, the cover 11 has a recess 13 which connects the recess 12 to the outer space (not specified in more detail) and which forms a passage for the safety finger 22, which thus unwinds to the locking lug 23 and unwinds inwards when it is wound up Winding shaft 7 can reach. If in this state an attempt is made to open the roller shutter by pushing it up, the safety finger is pressed against the lower edge of the stop plate 23 and the roller shutter 1 is prevented from any further opening movement blocked. It is impossible for the safety finger 22 to slip because the cam disk 21 blocks the passage of the safety finger 22 through the recess 13 in the cover 11 of the storage box 10 and thus prevents this movement.
  • Figures 4b to 4d show in steps the process of opening the roller shutter, roller door or roller door:
  • Figure 4b shows a position in which the winding shaft is rotated so far that the cam 21 no longer blocks this passage 13; in addition, the band spring 9 is tightened and has pulled the safety finger 22 off the stop plate and is pulled through the no longer blocked recess 13 in the lid 11 of the storage box.
  • the safety finger 22 lies in the recess 21.2 of the cam disc 21 on the shaft 7, followed by the uppermost rod 2.1 and the further rods 2, as shown in FIGS. 4c and 4d, which, because of their smaller width, lie between them the lids 11 of both storage boxes 10 arranged opposite one another are pulled through.
  • the roller shutter can now be raised unhindered so that the safety bolt (s) 15 are unlocked.
  • the roller shutter 1 is wound up in a conventional manner, the “wrapped” safety finger 22 remaining in the region of the recess 12 in the cover 11 of the storage box 10.
  • the roller shutter 1 is closed in the reverse order: first, the bars 2, all of which are the end strips 2.2, are wound, which run into the guide profiles 5. After (almost) complete unwinding, the uppermost rod 2.1 becomes free and slides with its safety finger 22 into the inlet area of the guide profiles 5.
