Definitions

  • the invention relates to securing building shafts, for example building light shafts, against burglary, according to the preamble of claim 1.
  • building shafts for example building light shafts
  • Such devices are preferably retrofitted in light shafts of buildings to be particularly secured, e.g. built by bank buildings or prisons.
  • the following main requirements are therefore placed on such devices: There must be easy installation and the device components must be well secured against any intrusion tools.
  • the anchoring part is formed by a box profile support which is doweled firmly on the light shaft wall and which is provided with several openings for receiving the locking bar ends.
  • the locking bars are formed by circular tubes, in each of which a likewise circular securing prism bar is accommodated, which, when sawing through the locking bar, should rotate therein and prevent the saw from advancing further.
  • the box section support must be dowelled in places that are located between the recesses for the individual locking rods, whereby to enable the fastening screws to be tightened in these areas between the Locking bars openings must be provided in the box section support, which are covered with sealing caps after completion of the assembly process.
  • this known device can only offer a low level of security against burglary, because the locking bars can be deformed with suitable bending and intrusion tools to such an extent that the internal security prism bar is jammed with the locking bar and can therefore no longer rotate.
  • This device has the further major disadvantage that the fastening screws of the box section support can be exposed very easily, even if the cavity in the box section support should be poured with concrete.
  • the invention is therefore based on the object of creating a device according to the preamble of patent claim 1 which, with simplified assembly, offers the greatest possible level of security against break-ins.
  • a separate fastening base is provided for each locking bar of the securing device, which, due to the snap-body locking device according to the invention, can accommodate the locking bar in such a way that it completely covers the fastening screw.
  • the fastening screw of the fastening base can therefore no longer be exposed without removing the rod, so that the device is considerably safer.
  • the assembly of the securing device is particularly simple because the individual fastening bases can first be screwed tightly before the respective locking rods are inserted into the bases. The locking bars can then face the fastening screws either with the end faces or with the outer surfaces of the end sections.
  • the further step according to the invention serves to design the locking bars in such a way that they are reliably protected even from the most powerful burglary tools that work either mechanically or thermally.
  • the locking rod is designed as a polygon prism, which is preferably mounted so that the bending resistance moment of the prism rod cross section becomes particularly large in the directions that are particularly relevant to the stress of the locking rod in an attempt to break open or break in by attaching any power lever tool.
  • a locking bar which is formed by a hollow profile tube with a square cross-section, is installed in a vertically extending light well, for example, in such a way that the outer surfaces of the locking bar form an angle of 45 ° with the vertical light well walls.
  • the locking bar can oppose a large bending moment of resistance to a power tool, for example a jack, which exerts a horizontally directed force on the locking bar.
  • the shape of the locking rod according to the invention leads to the further significant advantage that the interior in the locking rod deforms only insignificantly even under the action of large forces, so that the securing prism rod accommodated in the interior of the locking rod can continue to reliably fulfill its special function even when subjected to great force .
  • a particularly advantageous further development is achieved with the features of subclaim 2.
  • This further development ensures that a completely closed cavity is formed in the interior of the locking rod, which has a particularly advantageous effect when the building security system is operated with thermally operating break-up devices, for example with sweat - or cutting torches to be broken open.
  • the closed space in the locking rod when exposed to high temperatures from the outside when the cutting torch is attached leads to the build-up of a relatively high pressure inside the locking rod, which leads to setbacks of the cutting flame when the locking rod wall is broken. This makes it difficult to sever the locking bars.
  • an additional function is also transferred to the closure body, which in the accommodation of the snap body Snap body lock is located. As a result, the constructional complexity of the safety device is kept at a low level.
  • the snap body lock has two steel pins which are supported against one another via a compression spring and are guided in a diametrically running bore of the closure body, so that the snap body lock on the one hand reliably secures the locking rod against being pulled out when it is on it Large tensile forces act, whereby it additionally ensures that the steel pins can be pressed outwards with great forces even if only a small installation space can be kept free for accommodating the snap bodies.
  • this development additionally ensures that the compression spring does not reach the annealing temperature even when the edge-side end sections of the locking rod have been heated for a long time, so that the snap-body locking works fully reliably even after a long exposure to a cutting torch.
  • a further break-proof design of the device is achieved with the development according to subclaim 3.
  • the design of the interior of the locking bars in the form of a polygon prism on the one hand reduces the bending moment of the locking bar only insignificantly, but on the other hand ensures that in the Corner areas of guiding cavities are created in which easily rotating steel roller cores of relatively small diameter can be accommodated. Due to the above-mentioned design of the locking rod according to the invention, these guide cavities for the steel roller cores can only be pressed together with great difficulty, so that pinching of the steel roller cores is largely ruled out.
  • the steel roller cores can still rotate freely and smoothly in these cavities due to their flexibility when a cutting tool that is attached from the outside and penetrates the locking rod hits the steel roller cores. A further severing of the locking bars is therefore not possible.
  • a square profile tube is used as a locking rod and a circular cylindrical tube is used as a securing prism rod, four guide cavities are distributed evenly over the circumference of the locking rod, so that the locking rod cannot be sawn through or severed from either side.
  • the steel roll cores can be formed in one piece without being accepted as a result of jamming in the guide cavities.
  • the cross section of the guide cavities within the locking bar can be optimized in such a way that no clamping gaps arise.
  • an embodiment of the securing hollow prism bar as an octagonal hollow prism bar has particular advantages.
  • the steel roller bars can be made longer than the locking hollow prism tube under guidance on the turned-on pin, thereby achieving is that the steel rolling pins reliably protrude into the recess of the mounting base when the locking rods are fully assembled.
  • the screwed-on pin of the closure body closes the interior of the hollow prism rod, so that the above-mentioned securing effect is further enhanced when the securing device is processed with a cutting torch.
  • the fastening base also has the outer shape of a polygon prism
  • the locking rods are particularly rigidly anchored, which additionally contributes to the functional safety of the securing device.
  • this shape also has advantages in terms of production technology if the shape of the polygon prism of the fastening base is adapted to the polygon prism of the locking rod. In this way, the simplest components, i.e. with semi-finished products available at low prices on the market, e.g. of profile tubes and steel plates to weld a mounting base with all the advantages mentioned above.
  • the construction according to subclaim 4 is particularly advantageous if the diaphragm plate, i.e. the inside surface of the diaphragm plate is used as a contact surface for the snap bodies pressed outwards.
  • the outlay in terms of device technology is further reduced in this way.
  • the design of the mounting base as a cast part makes it possible to further increase the functional and break-open security of the device by providing material accumulations at predetermined locations that do not interfere with the assembly or insertion of the locking rods in the mounting base, and which are intended to accommodate additional securing devices serve.
  • the length or the height of the fastening base is preferably selected or matched to the height of the fastening screw or to the dimensions of the closure body in such a way that in the final assembly state of the locking rod the securing hollow prism rod also still overlaps with the fastening base in the axial direction. If, for example, a securing round rod is used in this embodiment, which is freely rotatably received in the locking rod, the securing round rod can be located in the entire area between the two fastening sockets does not offer reliable protection against cutting or sawing through the locking rod.
  • the mounting base In order to additionally secure the mounting base, it can accommodate steel roller pins in the areas that lie radially outside of the area covered by the locking rod, which are freely rotatable in hermetically sealed bores.
  • the fastening base can be provided with rod rolling pins aligned parallel to the locking rod, which extend along the fastening base so far that their ends overlap with the above-mentioned steel roller cores.
  • the receiving bores for the steel rolling pins which rotate easily when a sawing or cutting tool is attached can be provided both in a fastening base designed as a welded construction and in a fastening base designed as a cast part.
  • training as a cast part has the particular advantage in this case, because in this case simple material accumulations in the area of the corners of the polygon prism recess make it possible to create a blind hole from the anchoring foot of the mounting base, which is used to hold the steel rolling pins.
  • the hole originates from the anchoring foot, it can be sealed watertight after the steel rolling pin has been inserted using a sealing body that is not particularly secure, after it has been filled with any suitable lubricant. This ensures that the steel rolling pin still rotates safely and reliably in the blind hole even after a long period of operation when a sawing or cutting tool hits it.
  • the shape of the locking rod can of course be varied within wide limits; However, it has proven to be particularly advantageous to design the locking rod as a hollow profile with a square inner and outer contour.
  • the securing hollow prism rod can also have a wide variety of shapes, for example as a circular cylinder tube or as an octagonal hollow prism rod. It should be noted, however, that training as a polygon prism rod only leads to particularly high security against break-in if steel rolling cores are additionally provided in the cavities remaining between the shear hollow prism rod and the locking rod.
  • an additional security level can be implemented by inserting a further steel core or a plastic core or a further securing steel tube into the securing hollow prism bar.
  • a plastic core is inserted in the securing hollow prism rod, it can be ensured, on the one hand, that a separating tool, for example equipped with diamond teeth, becomes largely ineffective when it hits this plastic rod by filling the chip pockets with this plastic; on the other hand, through a suitable selection of the chemical composition of the plastic, special effects, such as e.g. strong smoke development or explosive effects, which strongly disturb the burglar.
  • interlocking prism tubes made of different materials can be arranged in the locking rod, which consist of different base material. This measure then makes it even more difficult to break open the locking rod with a cutting torch by taking advantage of the different material reactions.
  • the surfaces of the different prism tubes that are in direct contact with one another are coated with identical materials, for example galvanized.
  • FIG. 1 schematically shows a light shaft 1 to be secured against burglary, as is provided, for example, in prison buildings.
  • the axis 2 of the light well 1 extends in the illustrated embodiment in the vertical direction.
  • Extending in a plane perpendicular to the light shaft axis 2 is a hollow locking rod 3 spanning the light shaft 1 transversely, the ends 4 and 4 'of which are fixedly received on both sides in an anchoring part 5.

  • the fastening base 5 has a base plate 7 or (according to FIG. 2) 7 ', to which a prismatic pipe socket 8 for receiving the locking rod end 4 or 4' is connected.
  • the locking rod 3 is in this way received with its ends 4 and 4 'in a form-fitting manner in the mounting base 5 and secured against being pulled out by means of a snap-in body lock, which will be explained in more detail below.
  • the snap body locking has in particular the advantage that the securing mechanisms to be described in more detail below are not subjected to any internal stresses within the mounting base 5 and / or the locking rod 3 during assembly.
  • the fastening bases 5 are fastened to the shaft wall in such a way that the fastening screws 9 (see FIG. 10) come to rest in the axial extension of the locking bars 3 and are therefore completely covered by the locking bars 3.
  • the prismatic locking bars 3 with a square cross-sectional area are arranged or received in the mounting bases 5 such that the bending resistance moment of the locking bar 3 is parallel to the shaft axis 2 or in a plane perpendicular to the shaft when the force is applied Shaft axis 2 becomes particularly large.

  • This free rotatability is ensured, for example, when the locking rod, as shown in FIGS. 3 and 4, is designed as a prism tube with a square cross section and the securing hollow prism rod 11 as a circular tube.
  • the rotatability of the locking hollow prism rod 11 ensures that it can rotate freely within the locking rod 3 when a sawing tool or separating tool penetrates the locking rod 3 from the outside and hits the locking hollow prism rod. At this moment, the sawing tool can no longer penetrate into the locking bar 3.
  • a locking body 12 closing the locking rod 3 is provided, the shape of which is adapted to the inner cross section of the locking rod 3, so that it completely seals the locking rod 3.
