Definitions

  • the present invention relates to a device in connection with a protection for through-cutting, to prevent cutting through of an anti-theft device, according to the preamble of claim 1.
  • a variety of anti-theft devices and breakthrough protections are known. Most anti-theft devices however have the drawback that they are fairly easy to force if for example using a cutting machine with a rotating cutting disc, by which a fast through-cutting often can be achieved. This is particularly the case for chains or bars commonly used as parts of anti-theft devices or breakthrough protections.
  • a common way of rendering a cutting through more difficult is to make the component parts of a very hard/hardened material. Such materials are however most often brittle at a low temperature, which has meant that the use of so called cooling sprays has become an alternative breakthrough method, the spray being used to shock freeze the parts where after they can be broken by hammer.
  • a device in connection with a protection for through-cutting is for certain known from US 91,342, to prevent the cutting through of an anti-theft protection, which device comprises an elongated casing unit inside which a protective device is arranged, which protective device comprises at least one member arranged before final cutting through to give rise to a pinching force that prevents continued cutting through of the casing unit, said member being formed as an elongated rod-shaped unit resiliently biased inside said casing by means of at least one resilient member arranged inside said casing and arranged by one of its ends to exert a compressive force on a section of said rod-shaped member.
  • This device however only results in a limited protection for through-cutting and requires a costly and relatively bulky surrounding unit, in order to arrange for the biasing of the rod-shaped units. Accordingly, it is a costly design only giving a limited protection for through-cutting.
  • the solution according to the invention an efficient protection against through-cutting is achieved, which can be produced at a relatively low cost and accordingly has a wide field of application where ever a protection of this kind is found necessary.
  • the protection for through-cutting according to the invention can be made of non-hardened materials and accordingly it is not susceptible to cold/shock breaking. Also the production costs are favoured by the fact that the choice of materials is not critical.
  • the invention relates to a unit protecting against through-cutting and also to the use of a device or unit, respectively, according to the invention, in connection with a boat.
  • Figs. 1, 2 and 3 show protective members 2 inside a cylindrical metal casing 1, which protective members have the form of three round bars 2a-2c suitably also being of metal.
  • the casing unit 1 is closed by a lid 4, 5 at each end thereof.
  • One of the lids 5 is in contact with one of the end sections 2 of the three parallel bars 2a-2c.
  • the other lid 4 is in contact with one side of a helical spring 3, the other side of which presses against the other ends 20 of bars 2a-2c. Accordingly, the spring 3 is biased between one of the lids 4 and bars 2a-2c, such that each of the bars 2a-2c abuts against the opposing lid 5 by this spring-load.
  • Fig. 4 shows the same cross-section as in Fig. 3, but with a geometrical marking in the form of a dashed circle 6A.
  • This circle is intended to show the largest possible circular area able to be formed in the free space between the circular casing 1 and the bars 2a-2c. It is advantageous to arrange the unit such that this cross-sectional area 6A does not exceed the cross-sectional area 2A of any one of the bars, whereby it is prevented that a portion of a bar can be longitudinally moved after having been cut through.
  • Fig. 5 shows a modified embodiment of a device according to the invention. Largely, this device is similar to that described above. The only difference is that an additional spring 3' is arranged inside the casing 1, so that one spring 3, 3' is arranged at each lid 4, 5. In this embodiment, the spring load biasing is accordingly exerted from both ways onto the bars 2.
  • Figs. 6 and 7 show a unit comprising a plurality of devices 1, 1', 1", 1"' inside a rectangular casing 7.
  • four devices according to the invention. These are fixed at one corresponding corner each inside the casing 7, such that they extend in parallel with the extension of each respective longitudinal corner edge 7A of the casing 7.
  • the casing 7 is closed by rectangular plates 8, 9.
  • a relatively large free space 10 is formed between the four protective devices.
  • the four protection devices 1-1"' can advantageously be spot-welded 12 at a few spots along the longitudinal direction of the outer casing 7, such that if the outer casing 7 is cut all the way around, the total unit will be united all the same by these spot-welds. Even at a successful cutting of an end piece 9, the unit would be united in one piece thanks to the spot-welds 12.
  • Fig. 8 shows an example of how a unit according to Figs. 6 and 7 can be arranged in order to prevent theft of a boat engine.
  • a boat 11 is provided with such a unit 7, along the upper end of the stern.
  • a boat engine that thereafter is locked to the stern can not easily be stolen by cutting a portion of the stern, which is a method currently used to steal boat engines.
  • a unit 7 according to the invention can be arranged on other apparatuses/objects, in order to prevent corresponding thefts or sabotages.
  • Figs. 9 and 10 show a preferred principle to make secure corners/transitions for a unit according to the invention (suitably, an outer frame structure 7, 8, 9 is used according to the principles shown in Figs. 6 and 7, but for the purpose of clarity only an embodiment without such an outer casing is shown).
  • Fig. 9 shows in perspective, as seen obliquely from above, a corner according to the preferred principle, and Fig. 10 shows the same corner as seen from straight above. It is shown that each part unit comprises four devices 100-103 and 101'-103', respectively, according to the invention.
  • One part unit 100-103 consists of two upper devices 100, 101 that are arranged in parallel with each other, and two lower devices 102, 103 that are also arranged in parallel with each other, such that the four devices 100-103 form a type of elongated rectangular part unit.
  • the devices 100, 101 and 102, 103, respectively, are of equal length, the lower devices 102, 103 being considerably much longer than the upper devices 100, 101.
  • the lower pair 102, 103 is adequately much longer than the upper pair 100, 101 that the distance between the ends of the respective pairs well exceeds the double width/diameter of a single device.
  • a space is formed on top of the lower pair 102, 103, at the extension of the upper pair 100, 101, in which space the outer ends of an upper pair 100', 101' of a perpendicularly arranged second part element 100'-103', can be arranged.
  • a lower pair 102', 103' of this second part unit 100'-103' is adequately much shorter than the upper pair 100', 101', such that enough space is formed for the lower pair 102, 103 of the first part unit 100-103 to be accommodated inside that space.
  • a corner is created that consists of four crossed devices 102, 103, 100', 101', which means that a secure protection for through-cutting is obtained also in the area of the corner.
  • a weak point of the structure may be the end pieces 4, 5 enclosing the spring elements 3.
  • the ends are physically positioned such that cutting is rendered impossible, or at least is considerably aggravated, for example by being positioned below ground or shielded by some surrounding element.
  • the choice of material for the end plates 4, 5 can advantageously be of a harder material than for other details, which means that attempted removal of an end piece 4, 5 by cutting it off will be difficult, and that a cutting tool is guided thereby rather to cut inside the protective element itself, whereby any one of the spring biased elements 2 is triggered.
  • the invention is not limited to what has been described above but may be varied within the scope of the claims. Accordingly, it is e.g. realised that the number of protective members 2 inside a casing unit 1 can be varied from in certain cases a single one being considered enough, and up to a large number. In the same way, it is obvious that more than one spring 3 can be applied or arranged in parallel, for example such that each bar 2 is provided with its own compressive spring. If the object to be protected is a strut, a wire or a complete lock device e.g., it is possible to position the spring biased elements between inner and outer casings, such that a protected cavity is formed at the centre of the inner casing. Furthermore, it is realised that the invention is not limited to a circular shape bar.
  • a variety of rectangular shapes can be used both for the casing unit 1 and for the protective members 2.
  • other types of resilient members can be used than helical spring 3, such as leaf springs, cup springs, gas springs, rubber elements (optionally reinforced) etc.
  • a separate spring member 3 can be avoided by exerting a large enough bias on the bars 2, by means of the lids 4, 5, the lids in such case preferably being made of a material that is more elastic than the bar 2 itself.
  • Another conceivable alternative is to deep freeze the bar members 2 before they are inserted in the casing unit 1, the casing unit in that case suitably being of room temperature (or being heated), where after one lid 5 is tightly applied (e.g. by means of threads) against the bar member(s) before the lid is fixed (e.g. by welding).
