Description

Intrusion prevention device

Technical field

The present invention relates to an intrusion prevention device that is attached to a building, for example, a fence, a fence, a wall surface in the vicinity of a building window, etc., and prevents illegal intrusion into a site or a building. More specifically, the present invention relates to an intrusion prevention device that physically prevents intrusion into a site or a building and does not impair the appearance of a building.

Background art

Conventionally, various devices such as surveillance cameras and intrusion detection devices have been developed in order to prevent illegal intrusion into a site or a building. However, these can't stop the intrusion by simply photographing or detecting a trespasser. For this reason, when these devices are installed, the monitoring staff must constantly monitor them, and if they find an illegal intruder, they must take measures such as preventing it and reporting to the police. For this reason, these devices have a problem that their installation cost and operation cost are high.

[0003] In order to physically prevent illegal intrusion at low cost, it is effective to stretch barbed wire on a fence or the like. However, if the barbed wire is stretched in this way, the appearance becomes intimidating and the appearance of the building is remarkably damaged, so it can only be applied to factories and material storage places, and it can be installed in houses, hotels, hospitals, public facilities, etc. That is difficult in practice.

[0004] In addition, in order to stretch barbed wires on fences or the like, struts are projected on the fences or the like at predetermined intervals, and a plurality of barbed wires are stretched between these struts. It is common to set up. However, in such cases, if you wear thick leather gloves, etc., the barbed wire in the vicinity of the column may be caught, and it may climb up easily by climbing with a footrest force.

[0005] In addition, when laying barbed wire, it is more effective to lay in a three-dimensionally bent shape such as a spiral than to stretch it in a straight line. Is more intimidating and cannot be applied to special buildings.

[0006] Further, when the barbed wire is stretched and handled, these are entangled or immediately. There is a possibility that the worker may be injured, and it takes time and labor to lay this barbed wire, and there is a problem that the cost of the laying becomes high.

[0007] In order to solve such problems, various intrusion prevention devices have been conventionally developed. For example, Patent Document 1 discloses a structure in which a plurality of barbed objects are formed by cutting an edge of a band-shaped metal plate obliquely. This can be rolled into a strip and stored in a compact. When laying, the banded metal plate is pulled out and twisted so that the barbed body protrudes and exhibits an intrusion prevention effect. . This one is easy to lay and has a high intrusion prevention effect, but it still has a poor appearance and is not much different from conventional barbed wire in this respect.

[0008] Further, Patent Document 2 discloses a stainless steel wire attached with a synthetic resin member having star-shaped stabs at predetermined intervals. Although the appearance is improved to some extent, the appearance is still intimidating, and it takes time and effort to lay such wires as with conventional barbed wires.

[0009] Further, Patent Document 3 discloses a material in which a metal plate is punched to project a number of sharp claw pieces. This is easy to install and is only placed on the upper surface of the wings and the hood which seems to improve the appearance to some extent, and the intrusion prevention effect is not so high.

[0010] Further, in Patent Document 4, a barbed cylindrical body provided with radially projecting barbs is rotatably attached to the upper edge of the fence body. This is a force that improves the appearance to some extent. The intrusion prevention effect is not very high. Also, the structure is complicated and the cost is high.

Problems to be solved by the invention

[0011] The present invention provides an intrusion prevention device for a building that does not impair the appearance of a building such as a fence, a fence, or a building, and can reliably prevent illegal intrusion. Means for solving the problem

[0012] The invention according to claim 1 has an elongated handle member and a plate-like member projecting at least slightly from the tip or middle of the handle member. A plurality of piercing portions project from the edge of the plate-like member.

[0013] Further, according to a second aspect of the present invention, there is provided a mounting base that is attached to a building, and the handle member is projected from the mounting base force, and a distal end portion or an intermediate portion of the handle member is provided. The plate-like member protrudes at least slightly.

[0014] Further, according to the third aspect of the present invention, the handle member has a bent shape that can be arranged along a building, and a plurality of the plate-like members protrude from an intermediate portion of the handle member. Established

[0015] Further, in the invention according to claim 4, the plate-like member is formed of a metal material, and the piercing portion is formed by a cut portion that is obliquely cut into an edge portion of the plate-like member. The triangular portion thus formed is bent in a bowl shape in the thickness direction.

[0016] Further, in the present invention according to claim 5, the plate-like member is arranged three-dimensionally in a three-dimensional space, and the plate-like member arranged at least on the outermost side is provided. Has a piercing projection at its edge.

The invention's effect

[0017] In the intrusion prevention device according to claim 1, since the plate-like members are spatially and three-dimensionally arranged, when an intruder tries to pass, a part of the body contacts the edge of the plate-like member, The stab portion at the edge of the slidable contact is caught on clothes, and further intrusion is reliably prevented. For example, if this handle member is made to correspond to a branch or stem of a plant and the plate-like member is shaped like a plant leaf, the entire intrusion prevention device can be shaped to resemble the shape of a plant, Architectural decoration It has the same decorative properties as hardware and does not impair the appearance of the building.

[0018] In the intrusion prevention device according to claim 2, the plate-shaped members are more efficiently spatially and three-dimensionally arranged, and more effectively contact and slide contact with the intruder's body. It is effectively caught on the body and exerts a greater intrusion prevention effect. Moreover, this shape can imitate the whole invasion prevention device which is close to the form of a plant more closely to the form of a plant, and the appearance is improved. [0019] In the intrusion prevention device according to claim 3, the plate-like members are more efficiently spatially and three-dimensionally arranged, and more effectively contact and slide contact with the intruder's body. It is effectively caught on the body and exerts a greater intrusion prevention effect. Moreover, this shape can imitate the whole intrusion prevention device close to the shape of a vine plant more closely to the shape of a plant, and the appearance is improved and the manufacture is easy.

[0020] The intrusion prevention device according to claim 4 can easily and efficiently form a large number of stabs, and if a notch is formed by a shearing tool or a shear mold, a triangular shape formed by the notch is formed. Since the portions are automatically curved to form stabs, these stabs can be efficiently formed. Further, the piercing portion formed by such a cut has a very sharp tip and is bent in a bowl shape, so that a great invasion prevention effect can be exhibited.

[0021] Further, the intrusion prevention device according to claim 5 has a piercing portion protruding from an edge of the outermost plate-like member among the plurality of plate-like members spatially arranged in three dimensions. It is not. Therefore, if you pass nearby, care for the plant, and even if you accidentally touch this intrusion prevention device in other cases, the outermost plate-shaped member is not formed with a stab, so you will be injured. There is no. In addition, when an illegal intruder tries to intrude, it catches on the stab portion of the internal plate-like member, so that the intrusion prevention effect is exhibited.

BEST MODE FOR CARRYING OUT THE INVENTION

[0022] The intrusion prevention device of the present invention is composed of an elongated handle member and a plate member, and the plate member protrudes from at least one of the distal end portion and the intermediate portion of the handle member. A plurality of stabs are formed on the edge of these plate-like members.

[0023] Therefore, since these plate-like members are spatially and three-dimensionally arranged, when an intruder tries to pass, a part of the body comes into contact with and slides on the edge of the plate-like member. The stabbed part of the sword gets caught on clothes and other intrusions are reliably prevented.

Example 1

Hereinafter, Embodiment 1 of the present invention will be described with reference to FIGS. 1 to 5. The thing of this Example is attached to a fence or a fence, imitates the shape of a leaf and a branch of a nora, and was comprised so that the effect as an architectural decoration hardware might be exhibited. [0025] Reference numeral 1 in the figure denotes a mounting base, which is configured to be mounted on a block rod or the like. The mounting base 1 is formed to have a predetermined length, for example, a unit length of 930 mm or 1000 mm, and is attached to the block 塀 2 so as to be convenient for transportation and mounting.

[0026] A plurality of handle members 3 protrude from the mounting base 1. These handle members 3 are configured to have appropriate flexibility and elasticity. For example, in this embodiment, an iron wire having a diameter of 5 mm is used, and a base end portion thereof is attached to the mounting base 1 described above. Welded. The handle member 3 has a decorative portion and is bent at an intermediate portion so that the complexity, that is, the stagnation direction cannot be predicted when an external force is applied to the handle member 3. Further, in this embodiment, a relatively short support member 4 is projected by welding at the tip of these handle members 3, and this shape simulates a leaf branch of a rose. These handle members 3 have the same basic shape, but are projected with a mixture of several types with different bent shapes, which increases their complexity and improves decorativeness. Is configured.

[0027] Then, plate members 5 are attached to the tip portions of the handle member 3 and the support member 4, respectively. In the case of this embodiment, these plate-like members 5 are formed by punching a steel plate having a thickness of 1. Omm, and have a shape simulating a rose leaf. The base end portions of these plate-like members 5 are formed in a cylindrical shape to form attachment portions 6, and the tip portions of the handle member 3 and the support member 4 are inserted into these attachment portions 6. It is attached by spot welding from above.

[0028] In addition, a large number of stabs 7 are formed on the periphery of these plate-like members 5 in a body-like manner. As shown in FIGS. 2 to 5, these piercing portions 7 are formed with diagonal cuts 8 at the edges of the plate-like member 5, and the triangular portions formed by the cuts 8 are plate thicknesses. Curved in the direction. When these piercing portions 7 are formed, as shown in FIG. 5, if a shearing tool or a shearing die having a pair of shearing blades 9 and 10 having an angle with each other is used, as shown in FIG. Since the above-described triangular portion is automatically curved in the thickness direction at the same time as the cut portion 8 is formed, it is not necessary to bend in a separate process.

In this embodiment, as shown in FIG. 3, the stab portion 7 is provided on the left and right edge portions of the plate-like member 5. For example, at the right edge, the piercing part 7 protrudes to the front side of the plate-like member 5, and at the left edge, the piercing part 7 protrudes to the back side of the plate-like member 5. It is structured as follows. With this configuration, even if the intruder's body contacts the back side or the front side of the plate-like member 5, the intruder's body will be drawn to the piercing part 7 on either side. Of course, the piercing portions on the left and right edges may protrude in the same direction on the back side or the front side in accordance with conditions such as the configuration of the entire intrusion prevention device.

[0030] The tip 7 of the piercing portion 7 formed by the edge notch 8 is extremely sharp. The protruding dimensions and bending angles of these piercing parts 7 are set according to the overall size and installation conditions of the intrusion prevention device, but even an intruder may not damage the body. Since it is not preferable, the size and the angle should be such that the intruder will be dressed and give the intruder a slight pain.

[0031] Further, the cut portions 8 of the plate-like member 5 are cut obliquely from the front end side to the base end side of the plate-like members 5 imitating rose leaves, and thus the piercing portions 7 Is projected toward the distal end side, but is curved toward the proximal end side. Therefore, when clothes of illegal intruders are hooked on the stabs 7 of these plate-like members 5, they cannot be easily separated, and a great intrusion prevention effect can be obtained. In general, the leaves of leaves and other leaves of plants and plants have a sense of incongruity when the piercing portion 7 with many serrated irregularities facing the tip side is projected in the above-mentioned direction. The effect as a decorative body is not impaired.

[0032] The handle member 3 and the plate-like member 5 are also arranged in the same manner as natural plants, that is, as a whole, arranged from the center, that is, from the mounting base 1 toward the outside. Therefore, there is no sense of incongruity as a decorative body, and when the intruder's hand, foot, or part of the body is inserted between the handle member 3 or the plate-like member 5, it is curved toward the proximal end as described above. The stabbed portion 7 is configured to be caught on the invader's clothes and the like and cannot be easily removed.

[0033] The distance between the handle member 3 and the plate-like member 5 is such that when the intruder's hand or foot is pressed from above or from the side of the intrusion prevention device, the handle member 3 or The interval is set such that the plate-like member 5 stagnate and the intruder's hand, foot, or part of the body enters between them. Furthermore, as in this embodiment, the plate-like members simulating the shape of the leaves are more effective in preventing intrusion if they are arranged so that they are irregularly oriented in all directions rather than regularly arranged. Becomes higher.

Next, the operation of the first embodiment will be described. As shown in FIG. 1, this intrusion prevention device is continuously mounted on the block 2. In the case of this embodiment, the mounting base 1 is provided, and a barbed wire that is troublesome to handle is stretched by simply fixing it on the block 塀 2 with concrete bolts or the like. Installation work is more efficient than the case.

[0035] When a trespasser climbs over the block 塀 2 or tries to climb on the block 塀 2 to climb the roof of a building, he places his hand on the upper edge of the block 塀 2, You must also put your foot on this block 塀 2. Therefore, in such a case, the intruder's hand, foot, clothing, etc. are caught on the stab 7 of the plate-like member 5 of the intrusion prevention device, and further intrusion cannot be performed.

[0036] Further, in this embodiment, since the handle member 3 is squeezed or immediately, the handle member 3 and the plate-like member 5 are relatively densely arranged, so that the intrusion is performed by wearing thick leather gloves and wearing thick shoes. Even if the handle member 3 is grabbed and climbed or stepped on the upper handle member 3, the handle member 3 is squeezed into the piercing portion 7 of the plate member 5 of the adjacent handle member 3. The legs and hands are caught, preventing entry.

[0037] In this embodiment, in order to enhance the effect of preventing intrusion and enhance the decorativeness, the pattern member 3 and the plate-like member 5 are arranged relatively densely, and the plate member 5 is the body of the intruder. However, in order to reduce the cost, the pattern member 3 is arranged so as to cross the intrusion path if the gaps are arranged at a large distance in order to reduce the cost. In this way, if the intruder's body hits the handle member 3, it will itch and eventually the edge of the plate-like member 5 protruding from the handle member will contact the intruder's body and stab Part 7 can be caught in the body of the intruder and reliably prevented from entering.

[0038] Further, in this embodiment, the overall shape is in the form of a rose cocoon, which has the same decorativeness as that of a hardware of a building decoration, and does not impair the appearance of the building with a sense of intimidation. Therefore, it can also be applied to houses, hotels, hospitals, public buildings and the like.

Example 2

6 and 7 show a second embodiment of the present invention. In this, the handle member 13 is made of, for example, an iron wire rod having a diameter of 5 mm, and the handle member 13 is formed to be relatively long. Yes. The handle member 13 has a spatial or three-dimensional shape, such as a spiral shape or a bent shape, and is arranged as a whole so that it can be placed along a wall surface near the window of a building, a fence, or a building. Has a linear shape. A plurality of cruciform support members 14 as shown in FIG. 7 are projected from the handle member 13, and the same leaves as described above are provided at the tips of the support members 14. A plate-like member 5 having a similar shape is attached. Reference numeral 11 denotes a mounting bracket.

[0040] As shown in Fig. 6, the second embodiment configured as described above is attached along the top of the block rod 2 and the like. Since the handle member 13 is bent, the plate member 5 is spatially and three-dimensionally arranged. Therefore, when the intruder tries to get over the block 塀 2, the intruder's body comes into contact with the plate-like member 5, and the piercing portion 7 is pulled to prevent the intrusion. Even if the spacing between the plate-like members 5 is sparse, if the intruder's body hits the handle member 13 or the support member 14 as described above, the plate-like member 5 will eventually invade. Contact the person's body to prevent intrusion. Moreover, since the thing of this Example is the shape of a vine plant, for example, the shape of a vine rose, the appearance is not spoiled even if it installs this highly decorative.

Example 3

FIG. 8 shows a third embodiment of the present invention. This embodiment is suitable for mounting on net fences, lattice fences, etc., and has a simple shape to achieve design harmony with these fences and to reduce costs. ing. In addition, this embodiment eliminates the possibility of injury even if the intrusion prevention device is accidentally touched when passing nearby, caring for plants, etc., or in other cases.

[0042] In the figure, reference numeral 21 denotes a mounting base, which is configured to be mounted on a fence 23 or the like by a mounting bracket 22 or the like. A plurality of pattern plates 24 and 25 are projected from the mounting base 21. Each of the handle plates 24 and 25 includes a linear handle member 26 and a support member 27 projecting in a cross shape at the tip thereof, and the handle member 26 and the handle member 27 Plate-like members 28 and 29 are attached to the tip of each of them, and have a shape imitating a branch of leaves as a whole.

These pattern plates 24 and 25 are arranged at predetermined intervals in the front row 30a, the center row 30b, and the rear row 30c. Arranged in three rows. Therefore, the plate-like members 28 and 29 of the handle plate bodies 24 and 25 are three-dimensionally arranged in a predetermined three-dimensional space. Of these three rows of handle plates 24, 25, no piercing portion is formed on the outer side, that is, the edge of the plate-like member 28 of the handle plates 24 of the rows 30a and 30c. In addition, on the edge of the plate-like portion 29 of the handle plate body 25 in the center row 30b, a bowl-shaped stab portion 7 similar to that of the above-described embodiment is formed. Therefore, of the spatially arranged plate-like members 28 and 29, the edge of the plate-like member 28 located on the outermost side is not formed with a stab, and the plate-like member located on the inner side. A stab 7 is formed at the edge of 29.

[0043] In the third embodiment, since the piercing portion is not formed in the plate-like member 28 of the handle plate body 24 of the outer rows 30a and 30c, when passing in the vicinity thereof, care for implantation is required. In this case, even if a hand or the like touches the outer pattern plate 24 by mistake in other cases, the plate-like member 28 is not formed with a stab, so that it is not injured. If a trespasser tries to intrude, the handle plates 24 in both outer rows crawl at the weight of the trespasser or the limbs of the trespasser etc. The body of the illegal intruder gets into the space between the plate-like members 28 and is caught on the center row 30b, that is, the stab portion 7 of the plate-like member 29 of the inner handle plate body 25, and the entry is prevented. In this case, since the movement of the illegal intruder's limbs and the like is restricted by being fitted between the plate-like members 28 of the outer pattern plates 24, etc., the plate-like members of the inner pattern plate 25 The limbs and the like of illegal intruders that are caught on 29 piercing parts 7 are difficult to come off from the piercing part 7, and a great intrusion prevention effect is obtained.

[0044] In addition, the embodiment has a simple shape and is easy to manufacture, and does not feel uncomfortable with a net fence, a lattice fence, or the like. And as mentioned above, there is no injury even if touched accidentally, so it can be installed on low fences and fences, fences and fences with planting nearby, and has a wide range of uses.

[0045] In Example 3, the handle plates 24 and 25 are arranged in three rows, and the stabs are formed on the plate-like members 28 of the handle plates 24 in the outer rows. However, if it is installed in such a place that is less likely to be touched accidentally from one side, only the plate member 28 of the pattern plate body 24 of one outer row of both outer rows has its edge. Don't form a stab in the part! In this case, the pattern board may be two rows. [0046] In the case of this embodiment, the overall shape is not limited to the above, and may be the shape as in Embodiment 1 or Embodiment 2 described above. In this case, a stab is formed on the outermost plate member among the plate members arranged in the three-dimensional space! It is only necessary to arrange an insidious plate-like member.

Note that the present invention is not limited to the above-described embodiments. For example, in the above-described embodiment, the plate-like member is attached to the support member protruding from the handle member in order to make the arrangement of the plate-like members dense and approximate the shape of the rose. Even if the plate-like member is directly provided, it is easy to manufacture and the cost can be reduced. In the present specification and claims, the term “projection of the handle member also includes the case where the plate-like member is provided directly through the support member as described above or the like. Even when the intruder's body hits and stiffens, the plate-like member is attached in a spatially projecting relationship with the handle member so that the plate-like member contacts the intruder's body. It should be.

[0048] In the above-described embodiments, the handle member, the support member, and the plate-like member are configured to be shaped like a rose persimmon. However, other shapes of plants may be used. In addition, these handle members, support members, and plate members do not necessarily have to be shaped like plants, and they can be used as geometric shapes or abstract shapes, and can be used for building designs. The shape can be any shape.

[0049] Further, the piercing portion is not necessarily formed by obliquely cutting the edge portion of the metal plate-like member. For example, when the plate-like member is punched out by press molding, the edge portion is simultaneously formed. In this case, the stab portion is not necessarily limited to a curved hook shape, and may be an upright shape, a sawtooth shape, or other shapes. Further, the plate-like member is not limited to a flat plate shape, and may be curved or twisted so as to be closer to a plant leaf.

[0050] Further, in the above embodiment, the handle portion, the support portion, the plate-like member and the like are not limited to the force using a steel material, and a stainless steel material may be used. If the stainless steel material is used in this manner, the sharpness of the tip of the piercing portion can be maintained semi-permanently because painting is not necessary and the tip of the piercing portion does not rust. Further, the plate-like member is not limited to metal, but may be one in which the stab portion is integrally formed of a synthetic resin material. In addition, a highly elastic piano wire on the handle member, If a hard steel wire or the like is used, the body of the illegal intruder who is caught in the piercing portion will be more difficult to come off, and the intrusion prevention effect will be higher.

[0051] In the above-described embodiment, the intrusion prevention device attached to a fence, a fence, a building, or the like has been described. However, the present invention is not limited to being fixed to a building or the like, and the intrusion prevention device itself is used. It can be shaped like a fence or planting that cannot be climbed, and can be installed at the boundary of roads or sites to make it a portable intrusion prevention device. In order to block roads and sites so that they cannot be penetrated, barbed wire has traditionally been installed in a spiral shape, but if an intrusion prevention device with a fence-like shape as described above is installed, I do n’t feel intimidating. Industrial applicability

[0052] In the intrusion prevention device of the present invention, since the plate-like members protruding from the tip or middle portion of the handle member are spatially and three-dimensionally arranged, when an intruder tries to pass, The part comes into contact with and slides on the edge of the plate-like member, and the pierced part of this edge is caught on the clothes, and further intrusion is surely prevented. For example, if this handle member is made to correspond to a branch or stem of a plant and the plate-like member is shaped like a leaf of a plant, the entire intrusion prevention device can be shaped like a plant. It has the same decorative properties as architectural decoration hardware and does not impair the appearance of the building.
