Definitions

  • the present invention relates to an anti-intruder device for a door.
  • a wire can be pushed up through the gap between the door leaf and the floor to the door handle, or a camera pushed through the gap can provide a view of the inside of the building.
  • Any drop-down seal that may be present can be easily lifted beforehand using a suitable lever tool, e.g. a screwdriver or a goat foot, also known as a cow foot.
  • a door can be broken open with the help of a lever tool.
  • sealing devices which can be automatically lowered mechanically are known. They are generally used for doors in order to seal the lower gap between the door leaf and the floor against drafts, sound and light penetration.
  • a seal such as that shown, for example, in EP 0 338 974 is revealed. It has a housing rail, one arranged therein and one that can be raised and lowered relative to this Sealing strip with a soft sealing profile and an actuating mechanism for automatically raising and lowering the sealing strip. When lowered, the soft sealing profile rests on the floor and thus seals the gap between the door leaf and the floor. Examples of corresponding lowering mechanisms are in EP 0 509 961 , DE 3 526 720 , DE 3 418 438 and DE 3 427 938 disclosed.
  • the drop-down seals described have proven themselves in practice. However, if they are used on exterior doors or on doors that have to be specially secured, they have the above-mentioned disadvantages of poor burglary protection.
  • the lowered sealing strip can be easily lifted or a wire can easily be pushed under it.
  • EP 3 432 694 A1 discloses an automatic door gap seal with increased protection against break-ins.
  • the sealing profile has an inclined lip which is received in a sloping pocket of the threshold when the door seal is lowered and the door is closed. This is to prevent objects from being pushed through between the door threshold and the door leaf.
  • this device has the disadvantage that it can still be lifted by means of a goat foot.
  • the bag can fill up with bugs, leaves and other rubbish.
  • increased precision is required when assembling the device so that the bevel lip can be optimally accommodated in the pocket.
  • the angled lip is also exposed to increased forces when the door is opened and closed and must be replaced accordingly on a regular basis.
  • the burglar protection device according to the invention for a door has a fuse strip for arrangement on or in a door leaf of the door and for closing a gap between the door leaf and a door underside.
  • the safety bar can be moved from a raised position into a safety position in which it closes the gap when the door is closed.
  • the fuse strip has a defense element, the shape of which prevents the fuse strip from reaching underneath and prevents it from penetrating between the fuse strip and the underside of the door.
  • the shape of the defense element prevents a goat's foot or other break-in tool from being pushed under the protective device into the interior of the building.
  • a goat's foot or other break-in tool from being pushed under the protective device into the interior of the building.
  • the tool in particular the goat foot, is deflected and guided into an intermediate space within the safety bar. In this position, no further effective force can then be exerted on the fuse strip and thus on the door leaf.
  • the fuse strip has an extension which extends obliquely downward at least in the fuse position and which forms the defense element.
  • the extension is arranged at a lower end of the fuse strip extending in a longitudinal direction. It protrudes at least in the securing position of the rest of the securing strip in a transverse direction running transversely to the longitudinal direction and prevents reaching under and penetration. This is a simple and inexpensive, but also an extremely effective design of the fuse strip.
  • the fuse strip has a lower floor which runs horizontally at least in the fuse position and is directed downward, the lower floor approximating in a longitudinal direction extends over the entire length of the fuse strip.
  • the lower floor has an underside on which a spacer is arranged.
  • the extension is preferably arranged on the lower floor.
  • the extension is a downward sloping rib which extends over the entire length of the lower floor.
  • the rib is disposed at a longitudinally extending end of the lower tray and extends obliquely downward from the end of the lower tray from the lower tray. It forms an extension of the lower floor in the horizontal direction.
  • the spacer and the length or the angle of the rib are selected to match one another, so that they can be used on a flat underside of the door.
  • the shape of the threshold is preferably adapted. For example, it has a step or edge over which the extension runs when the door is closed.
  • the fuse strip can be designed in a simple manner if the lower base and the extension are designed together in one piece.
  • the fuse strip has a first side wall, wherein the first side wall extends upwards over the lower floor and wherein the lower floor and the first side wall are formed separately from one another.
  • This arrangement forms a defense element.
  • This embodiment can be designed with or without the extension mentioned above.
  • the fuse strip has a first angle profile, the first side wall forming a first leg of the first angle profile and a second leg of the first angle profile running approximately parallel above and adjacent to the lower floor. This embodiment is used to derive the force used or the deflection of the goat's foot or another break-in tool.
  • the fuse strip preferably has a second side wall, the second Side wall is connected to the lower floor and they together form a second angle profile.
  • the fuse strip can be brought into the fuse position in different ways. For example, it can be swiveled into this position. However, it is preferably held in a housing rail so that it can be raised and lowered.
  • the anti-burglary protection device preferably has a mechanical lowering mechanism for lowering and raising the security strip, as well as a mechanical actuating element which can be activated automatically when the door is closed and which acts on the lowering mechanism. These elements preferably correspond to the mechanisms used in known drop-down seals.
  • the burglar protection device can thus be used like a drop-down seal and built into the door. It preferably not only takes on the protective function against burglary, but also the sealing functions of the known drop-down seals.
  • the fuse strip can be at least partially made of a flexible material, in particular silicone or rubber.
  • the fuse strip has a sealing profile and it is designed as a sealing strip with a support rail.
  • the entire fuse strip or at least approximately the entire fuse strip is designed to be rigid, i.e. stable. It is preferably wholly or at least partially made of a metal, in particular steel. If the fuse strip has the angle profiles mentioned above, these are preferably made of a metal, in particular steel.
  • the fuse strip preferably has an essentially rectangular cross section. As a result, it does not offer any zones for applying leverage. It is preferably designed to be open at the top so that it can be connected to the lowering mechanism in a simple manner and in a space-saving manner.
  • the anti-intrusion device has the known lowering mechanisms of the known lowering seals.
  • protection against burglary is partially provided by the shape of the fuse strip described here supported by the choice of material, or by the choice of material described here, partially supported by the shape.
  • further means are also present which ensure protection against burglary, such as further locking elements which prevent the fuse strip from being moved out of the secured position by the action of external force.
  • These locking members can act, for example, on the lowering mechanism or on the pivoting mechanism of the device, but also on the safety bar. Or they can be a stop that holds the fuse strip in its secured position and that can only be removed again when the door is opened.
  • the burglar protection device comprises a threshold, the security strip closing the gap between the threshold and the door leaf in the security position and wherein the threshold has at least one step.
  • the step can, for example, lead down to the outside of the building. However, it can also be an increase, which is located below the fuse strip when the door is closed.
  • an elastic safety strip before or after the first safety strip.
  • this can be raised and lowered into a securing position, pivoted into this position or it is always at the same height.
  • their distance from the floor or from the threshold is preferably adjustable. It is preferably arranged at a slight distance from the threshold, the resulting gap being so small that no burglar tool can be pushed through the gap.
  • the burglar protection device has a security strip which has an elastic evasive body which, after elastic deformation, assumes its original shape again.
  • the elastic safety strip is designed to be elastic at least in its lower region facing the threshold. At least this area preferably consists of an elastically deformable plastic, for example a foam or a rubber. Materials that have a high level of force absorption and high resilience are particularly suitable.
  • the fuse strip extends in its longitudinal direction preferably approximately over the entire width of the door leaf. Depending on the variant, it is formed in one piece in its longitudinal direction or it has individual partial areas which are separate from one another, but which preferably adjoin one another.
  • This elastic safety bar can be lifted by a goat foot, but if the goat foot is withdrawn, it returns to its original shape. This means that no permanent passages can be created underneath the door through which other break-in tools, such as cameras, could be pushed.
  • This elastic safety strip can also be used as burglar protection in doors without a first safety strip, preferably in doors whose permanently deformable underside is only arranged after the elastic safety strip and which cannot be deformed without visual contact or open access.
  • the elastic fuse strip can be combined with a wide variety of first fuse strips. It can also be arranged between two first fuse strips or between a classic drop-down seal and a first fuse strip or between two classic drop-down seals.
  • the obstacle which prevents reaching under the first fuse strip, preferably follows the elastic fuse strip as seen from the attack side.
  • the obstacle is preferably part of the threshold and / or the first safety strip.
  • the term “locked” is understood in this text to mean that the safety strip rests on the threshold or ends at such a minimal distance from the threshold that this distance cannot be penetrated by conventional burglary tools. The same applies to the term “applied”. Here, too, there can be a minimal gap, which, however, prevents reaching through.
  • the term "reaching under” is understood on the one hand to mean that a lever tool cannot be pushed under the fuse strip enough to generate a lever effect. On the other hand, the term is understood to mean that a thin object such as a wire cannot be pushed onto the opposite side of the door leaf.
  • the "attack side” is the side from which unauthorized access to a building or a building interior is to be created. Usually the “attack side” is the outside of the building. The opposite side of the door is thus the “non-attack side”, which usually corresponds to the inside of the building.
  • the terms “outside of the building”, “outside”, “outside”, “inside of the building”, “inside”, “inside” and the like are also used. They are to be understood broadly in this text, so that they are not limited to outside and inside, but generally include “attack side” and "non-attack side”.

  • FIG. 8a to 8d there is not only a first upper toothing, which forms a drive described above, but it also has a lower toothing, which represents a safeguard against slipping.
  • the device in turn comprises the components already described, with a double-toothed locking support 820 being present.
  • a pivot arm 821 has an upper ring gear 823 and a lower ring gear 822, which forms the contact surface.
  • the swivel arm 821 can in turn swivel about a swivel axis 826 which is arranged in a stationary manner in the housing rail 1.
  • An upper rack 824 with teeth 825 is arranged on the slide and a lower rack 827 is arranged on the lowering bar, more precisely on the inner surface of the web.
  • FIG 9 is a further embodiment of the invention Burglar protection device shown.
  • the fuse strip 3 is designed as a sealing strip in this case. It has a rigid support rail 35, for example made of aluminum or steel, which preferably extends over the entire length of the housing rail 1. It can also be made longer or shorter.
  • a sealing profile is arranged on the support rail 35.
  • the sealing profile is made of a soft material, preferably silicone or rubber.
  • the sealing profile has the first and the second side wall 33, 30, the lower base 31 and the extension 32.
  • the sealing profile can be formed in several pieces. However, it is preferably in one piece, as shown here.
  • the lower floor 31 connects the two side walls 33, 30 to one another and forms a lower web.
  • the bottom is relatively thick compared to the side walls. Preferably it is relatively stiff. For example, it can have a greater Shore hardness than the side walls.
  • the extension is in turn designed as a protruding rib 32 directed obliquely downward. This rib 32 is also relatively thick, but thins towards the free end. It can also be relatively stiff, i.e. designed with a greater or greater Shore hardness.
  • the threshold 6 preferably has a step in the form of an elevation 64 in the area of the safety strip 3, which step corresponds to the angle of inclination of the extension 32. If the angle of inclination of the extension 32 is slightly larger than the inclination of the elevation 64, the extension 32 rests on with pretension. Reaching under with a goat foot or with a wire is made even more difficult.
  • This embodiment has the advantage that an optimal sealing function is combined with simultaneous burglary protection in the same component. This saves space and costs.
  • a door leaf F is shown.
  • a metal door is shown in the figures.
  • the door leaf F can, however, also be a plastic construction or a wooden door. It is preferably an outside door of a building.
  • a first door seal D1 On the underside of the door, preferably in a corresponding groove or receptacle, a first door seal D1, which is well known in the prior art, can be automatically and mechanically lowered. It faces the attack side A, i.e. it is usually arranged towards the outside of the building.
  • This first lowering seal D1 has the housing rail 1 and the sealing strip 3 'held therein such that it can be lowered and raised. It has the support rail 35 'and an elastomeric sealing profile with a first side wall 30', a second side wall 33 'and a lower base 31' connecting the two side walls 30 ', 33'.
  • An elastic safety strip 7 is held in the door leaf F behind this first lowering seal D1. It is preferably fastened to the door leaf F by means of a fastening bracket 72.
  • the distance to the floor or to the threshold 6 can be set by means of spacer elements 73.
  • the spacer element 73 is preferably a washer or a washer. The use of spacer elements 73 enables a simple height adjustment, although large forces can be absorbed. Other types of height adjustment are also possible, in particular stepless height adjustment.
  • the elastic securing strip 7 extends like the first and the second lowering seal D1, D2 described below, preferably over the entire width of the door leaf F and thereby defines a longitudinal direction.
  • the cross section of the elastic safety strip 7 and preferably also of the first and second lowering seals D1, D2 is preferably approximately constant over their entire length.
  • the elastic fuse strip 7 preferably has a rectangular cross section at least in its lower region. At least one lower area of the elastic securing strip 7 facing the threshold 6 is designed to be elastically deformable. Preferably, at least this area consists of an elastically deformable plastic, for example a foam or rubber.
  • the elastic fuse strip 7 preferably has a rigid base body 70, preferably made of metal or a hard plastic.
  • the fastening bracket 72 can be connected to this base body 70.
  • the lower area in the form of an escape body 71 is arranged on the base body 70. It is preferably molded on. However, it can also be connected to it in other ways.
  • the avoidance body 71 has a downwardly open U-shaped cross section. It is held in a groove in the base body 70 and protrudes from it on the lower end face. In the embodiment according to Figure 11 it is cuboid and fastened or molded onto the lower end face of the base body 70.
  • the evasive body 71 has a flat lower end face or it is itself provided with depressions and / or elevations. It preferably ends at a small distance from the threshold, so that it does not contact the threshold or the floor when the door leaf F is opened and closed.
  • the gap between the evasive body 71 and the threshold 6 is preferably so small that a break-in tool cannot be pushed through the gap without deforming the evasive body 71.
  • the deflecting body 71 extends in one piece over the entire length of the elastic securing strip 7.
  • the deflecting body 71 comprises a plurality of partial bodies 710 which are joined together in the longitudinal direction but are independent of one another. This is shown in FIG Figure 12 recognizable.
  • the threshold 6 preferably extends at least over the distance from the first lowering seal D1 to the second lowering seal D2. It can be designed in one piece or in several pieces in its surface over this area. In these examples it is made in one piece. It is preferably connected to a base body 6 'and rests on it. The base body 6 'is preferably attached to the building floor.
  • the goat's foot or another break-in tool may possibly subsequently get under the elastic safety strip 7.
  • the burglary tool cannot permanently deform the fuse strip. If the avoidance body 71 consists of a plurality of subsections loosely lined up one behind the other, this does not succeed even with two tools introduced next to one another. This prevents the view of the following, second drop-down seal D2. In addition, no leverage can be applied to the second drop-down seal D2. This protection is further enhanced by the fact that the second drop-down seal has the defensive element in the form of the extension 32.
  • the devices according to Figures 10 and 11 thus offer the combination of a double seal, thanks to the two drop-down seals D1 and D2, and optimal burglary protection, whereby the burglar protection can definitely meet the requirements of the standardized resistance class RC3 or a higher resistance class.
  • the elastic fuse strip can preferably also be combined with other fuse strips, in particular with the fuse strips according to FIGS Figures 1 to 8d .
  • the burglar protection device enables optimal burglary protection, even when using a goat foot or a wire loop as a burglary tool.
