Definitions

  • the invention relates to a device for securing a closure which can be wound up and unwound from this for windows or doors such as roller shutters, roller shutters, rolling grilles or the like, which are guided laterally and which are composed of rods or rod honeycombs.
  • rods are connected to one another in such an articulated manner that they can be rolled up onto a shaft arranged in the upper region of the window or gate lintel.
  • the hinged rods that form the closure are guided in lateral guide grooves arranged on the window or gate edge, so that they form a closing front in the lowered state.
  • the shaft can be operated for winding or unwinding either by a belt or by an electric motor.
  • rolling grilles that have a closure, in which a network of bent wire or shaped rod honeycombs are connected to one another in an articulated manner, so that they can be wound onto or unwound from the shaft in a manner similar to a roller shutter formed from rods.
  • roller shutters or roller shutters or rolling grilles there is an increasing demand that the lowered roller shutter in particular should be secured against forced pushing up.
  • the lowered hinged rods connected to the shaft are pushed into the shaft box to create an opening cross-section through which the building can be penetrated.
  • the shaft can be operated for winding or unwinding either by means of a belt pull or by an electric motor drive.
  • the motorized drives play the preferred role for roll-up safety closures, in which the protection against pushing up is taken over by the drive (gearbox, motor brake) (however, motor drives are not a requirement).
  • this locking mechanism represents a type of additional locking type on a roller shutter or a roller shutter, which is not infrequently affected by the constant up and down movement, so that its effect wears off over time, the corresponding bolts on the lower bar providing the holding force as desired.
  • At least two lockable or unlockable cooperating locking rods are arranged between the shaft and the lock, which lock the lowered lock against pushing up in the locked state, the locking rods being able to be wound onto the shaft in the unlocked state. Due to this arrangement, a security system for roller shutters or roller doors is created, which is integrated in the articulated bar or grille system. This security system is located in the area of the winding box between the shaft and the articulated closure, which is held and guided in the lateral guide grooves. As a result, it is also suitable for rolling grilles, since the securing bars are arranged so as to be protected against penetration by the mesh of the grille in the winding box, despite the possibility of access.
  • This system bridges with the securing bars at least the area between the upper opening edge area of the guide groove, the inlet, up to the rotatably mounted shaft, this area being locked by the securing bars so that a rigidification between the Shaft and the closure held in the side guide grooves is achieved.
  • the locking securing rods lock in such a way that they no longer offer a joint point over which the rods or grids arranged in the guide grooves can be pushed.
  • the locking rods thus form a rigid pendulum support between the shaft and the closure, so that when a force is applied to push up the roller shutter, it is directly repositioned by the shaft.
  • the securing rods are profiled and connected to one another in such a way that they are designed to be able to be pushed into one another for the locking blocking, the securing rods being connected to one another via joints in the pulled-apart unlocked state.
  • This design ensures that the securing rods, on the one hand, bring about a rigidity due to their displaceability relative to one another, that is, form a pendulum support, and, on the other hand, have an articulation, which is particularly necessary when the rods are rolled up.
  • the profile of the securing rod has a handle hook on which a shoulder is formed, to which a U-shaped profile connects, which forms the lower sliding area of the profile.
  • one leg of the U-shaped profile is expediently designed as an inwardly molded chamber hook. Due to this division of the securing rod into two, a profile is created in which, on the one hand, in the pushed-together state, i.e.
  • This design ensures a kind of tilt-free displacement within the U-shaped profile, the surface of the shoulder and the surface of the nose of the stick hook being guided parallel within the U-shaped leg profile, since in particular these areas on the inner walls of the chamber of the U- shaped profile with game.
  • the shoulder is offset by an amount relative to the U-shaped edge region of the profile via a recess of the stem, the amount corresponding approximately to the thickness of the second leg.
  • the second leg can slide on the back of the shoulder until it strikes the offset edge area of the profile.
  • the guide curve and the shoulder back formed in this way it is ensured that the upper securing rod with its U-shaped profile is always held on a secure displacement or guideway even without external guidance, so that the locking of the securing rods arranged with respect to one another according to the invention is "rigid". causes.
  • the guide curve in the transition area from the handle hook to the shoulder merges into a thickened area of the handle, which approximately fills the opening cross section that results between the hook nose of the first leg and the second leg. Due to this thickening guide curve, a stable shifting of the safety bars arranged relative to one another is ensured.
  • the interlocking safety rods slide apart such that the handle hook formed on the shoulder engages in the chamber hook arranged on the first leg, so that due to this design there is an articulated connection between the safety rods, which winds up the safety rods the wave allowed.
  • the securing rods have a curved outer profile, such that they are pushed together in a curve that is approximately from the exit of the lateral guide extends tangentially to the shaft.
  • a curve is specified which, on the one hand, is aimed at the outlet or inlet of the lateral guide and, on the other hand, is guided approximately tangentially to the shaft.
  • the safety bars cannot rest on protrusions in the area of the outlet or inlet of the side guides; they form in the locked state an arc guided to the shaft, which initiates the blocking forces in the shaft; and they will eventually be directed to the shaft while unlocking.
  • the locking is connected to a power transmission by the securing rods, it is advantageous if the switching off of a drive when the lower switching point is reached is not effected in a known manner by a limit switch provided on the drive motor, but by a limit switch triggered by this force reaction.
  • the side bearings of the shaft as flying bearings trained that allow a linear movement or a pivoting movement.
  • a limit switch advantageously a microswitch, is provided such that the microswitch switches off the drive motor in the event of a wave movement occurring as a result of the force reaction.
  • This shaft movement is advantageously designed as a linear movement lying in the direction of the inlet tangent, for which purpose the shaft bearings have corresponding, preferably dovetail or T-slot-shaped guides.
  • a brake ratchet with a shaft-fixed part and a winding box or building-fixed part is provided and the shaft is provided with a game that allows the shaft to shift at right angles to its axis, so that the positive locking mechanism when the shaft is displaced in Intervention can be brought.
  • This mechanical locking mechanism engages when attempting to push up due to the shaft displaced by the force applied during the pushing-up action and thus blocks the pushing-up action, the force required to overcome the locking mechanism being provided by the fastening of the part which is fixed to the shaft and to the building or winding box fixed part.
  • a locking disk connected to the shaft and provided with projections and recesses on its circumference, as well as a locking bolt arranged fixed to the wall, lintel or changing box and provided with at least one recess corresponding to the lugs, are provided, the recess (s) thus is / are that a nose of the locking disk can be inserted in a form-fitting manner in one of the recesses.
  • This ensures a safe lock against pushing up, since one of the lugs engages in a recess when the shaft is displaced, so that the force which is used to wind up the closure further is introduced into the winding box or into the wall.
  • the lugs or the projections remaining between the recesses have rounded apices; this design of nose or projection allowed an easy insertion of the nose into the recess when the shaft is displaced.
  • Such a locking mechanism is advantageously formed by a toothed wheel and a toothed rack (at least one latch), in which the part which is arranged opposite the toothed wheel forms a toothed rack.
  • the locking disk have a diameter that is larger than that of the shaft. This measure reduces the torque acting on the circumference of the locking disk in the ratio of the radii of the locking disk and shaft, so that the locking bolt is relieved.
  • FIG. 1 shows a side view of the device according to the invention for securing a (broken off) closure 1, which, as shown in the exemplary embodiment, is a roller shutter or roller shutter composed of bars, the top bars of which are designed as security bars 3, and which are connected to a shaft 2 are connected with a counterpart 2.3.
  • the securing rods 3 can be wound on and unwound from a shaft 2.
  • the safety rods according to the invention - here lifted out as safety rods 3.1 and 3.2 - are arranged lockable or unlockable cooperate, as shown in the individual representations of Figures 2 and 3, in which the tangent to the shaft 2 curving of the security rods 3.1 and 3.2 can be seen.
  • the securing rods 3.1 and 3.2 shows the locked state of the securing rods 3.1 and 3.2, in which position a rigidity is achieved in such a way that the closure 1 formed from rods which are connected to one another in an articulated manner is the roller shutter or the roller shutter door which is guided and held in the grooves in the lateral guides 1.1 secure against violent pushing up.
  • a rigid support is formed between the upper edge region of the guide grooves (not shown in more detail) and the shaft 2 due to the securing rods 3.1 and 3.2, which the hinged rods forming the shutter 1 or rolling shutter against the violent pushing up in the Guiding grooves 1.1 supports.
  • the securing device acts in such a way that it presses or holds the closure 1 into the lateral guide grooves 1.1 between the shaft 2 and the hingedly connected rods of the closure 1 which form the roller shutter, the roller shutter or the rolling grille, so that in the lowered state, it closes violent pushing up is prevented.
  • the locking bars 3.1 and 3.2 blocked in this way are due to their curvature on a curve that leads approximately tangentially to the shaft 2 from the outlet of the lateral guides 1.1.
  • FIGS. 2 and 3 This interaction of the securing rods 3.1 and 3.2 with respect to one another is shown in more detail in FIGS. 2 and 3, the individual securing rods 3.1 and 3.2 having an identical profile and being connected to one another in such a way that they can be pushed into one another for locking blocking.
  • the securing rods 3.1 and 3.2 - as shown in FIG. 2 - are pivotally connected to one another via a joint 4.
  • the profile of the securing rods 3.1 and 3.2 has a handle hook 5 in the upper region, on which a shoulder 6 is formed. This shoulder 6 is followed by a U-shaped chamber profile 7, with a chamber open at the bottom, which forms the lower sliding area of the securing rods 3.1 and 3.2.
  • the U-shaped chamber profile 7 has a first leg 8.1, which also has an inwardly molded chamber hook 9 at its free end. As can be seen from FIG. 2, the handle hook 5 formed on the shoulder 6 cooperates with the chamber hook 9 of the first leg 8.1 to form the joints 4.
  • the shoulder 6 and a nose area 5.1 of the integrally formed stick hook 5 run approximately parallel to one another; they are in the inserted state on the inner wall of the U-shaped chamber profile 7.
  • the shoulder 6 has a recess 11 and is offset by the amount of this recess 11 with respect to the U-shaped edge region of the chamber profile 7; this amount corresponds approximately to the thickness of the second leg 8.2.
  • a guide curve 13 is formed on the inside of the shoulder 6 and cooperates with the nose of the chamber hook 9 arranged in the U-shaped chamber profile 7. As can be seen from FIG. 3, this hook nose is guided on the guide curve 13 in such a way that the second leg 8.2 bears against the back of the shoulder 6.
  • the nose area on the guide curve corresponds to the displacement path of the second leg 8.2 on the back of the shoulder 6 13 led.
  • the guide curve 13 merges in the area of the handle 5.2, which forms the transition from the hook 5 to the shoulder 6, into a thickened area of the handle 5.2, which roughly corresponds to the opening cross section 14 that results between the hook nose of the first leg 8.1 and the second leg 8.2 fills out.
  • the illustrated and described interaction of the two securing rods 3.1 and 3.2 means that in the locked state of the two securing rods 3.1 and 3.2, the chamber hook 9 of the first leg 8.1 of the one securing rod 3.1 has its back on the U-shaped chamber profile 7 of the next securing rod 3.2 arranged underneath rests, while the second leg 8.2 rests on the shoulder 6 and the leg edge is supported on the recess 11.
  • the handle hook 5 with the integrally formed shoulder region 6 is completely absorbed by the U-shaped chamber profile 7, so that the securing rods 3.1 and 3.2 are rigidly connected to one another due to the pressure acting on them.
  • FIGS. 4 and 5 show a section through a shaft 2 of an armored roller shutter formed by rods 3, the middle of the locking disk 20 having been broken out (FIG. 5) in order to be able to represent the bearing for the shaft end 2.1;
  • FIG. 6 shows a side view of the shaft end 2.1 with storage and with a cut-off locking disk 20.
  • the top end rod 3.1 of the roller shutter is attached to the shaft 2 or the like on the shaft 2.
  • fixed counterpart 2.3 fixed; the adjoining securing rods 3 are guided in side guides 1.1 with the inlet 1.2, the lower end rod (not shown here) sitting on a window sill or the like (also not shown).
  • the securing rods 3 are lowered Closure 1 is pushed into one another in such a way that the blind of the closure 1 guided in the guide 1.1 is at least rigid in the area of the securing rods 3, and so the roller shutter can be regarded as an approximately rigid plate.
  • This nesting continues until the end rod and the counterpart attached to the shaft 2 2.3, so that by trying to push up the roller shutter, a force is exerted on the shaft 2, which causes this shaft 2 to fly in the direction of freedom relocated; this shift takes place in the upwardly open, U-shaped bearing shell 16.1 in the direction of "lifting".
  • the shaft end 2.1 is provided with a bearing journal 2.2 which is rotatably mounted in a bearing.
  • This bearing is formed by a bearing plate 16 with a U-shaped bearing shell 16.1 which is open at the top and which is fastened on a base plate 15, this fastening being designed according to the forces to be expected.
  • the bearing shell 16.1 of this bearing forms approximately an open “U” in which the pin 2.2, provided with a bearing 17 shown as a ball bearing, is inserted and rotatably supported there.
  • This type of storage gives the shaft end 2.1 and thus also the shaft 2 a play upwards, so that the shaft 2 can move upwards when trying to push up the roller shutter.
  • the roller shutter can be raised by a distance that corresponds to the distance between two disc or bolt recesses 23 or 27 from the locking disc 20 or the locking bolt 25, reduced by the transmission ratio, which in the range of approximately 1 when the roller shutter is unwound : 3 lies: this would correspond to a possible elevation of 3 mm if the recesses were 9 mm apart.
  • the shaft end 2.1 is provided with a locking disk 20 which is connected to the shaft end 2.1 in a manner secured against rotation.
  • This locking disk 20 has a circumferential rim 21, formed by disk projections 22 and disk recesses 24, which form a type of toothing (only shown in an upper sector - otherwise indicated).
  • This locking disc 20 raised together with the shaft 2.
  • the bearing shell 16.1 is fixedly arranged on the bearing plate 16, which has holes 18 for attachment to the wall or lintel or to a changing box.
  • the shaft end 2.1 lies with a pin 2.2 in the base of a recess in this bearing shell 16.1 and can be freely rotated in the bearing 17 by means of the pin 2.2.
  • journal which is mounted in a rotationally fixed manner in the bearing and which is rotatably mounted in the shaft 2, for example with a plain bearing bush; the height mobility is independent of the rotatable bearing.
  • the base plate 15 is, for example, anchored to the building with screws 18 'guided through the bores 18; on it - again fixed to the building - a locking bolt 25 is arranged, which is fastened by means of the bolts 26.
  • This locking bolt 25 is provided with bolt recesses 27 and bolt projections 28, which are designed analogously to the disc projections 22 and disc recesses 23 of the ring 21 of the locking disc 20.
  • roller shutters which are formed by honeycombs, since here, when trying to push up such a roller shutter, a force is also transmitted to the shaft, which causes the protrusions and the recesses to engage and thus engage.
