Description

  The present invention relates to a security screen device. More specifically, the present invention relates to an improvement in the structure of a security screen device provided on the outer wall of a building.

  2. Description of the Related Art Conventionally, for the purpose of crime prevention such as prevention of intrusion of a thief or the like, a window or the like formed on a building outer wall is covered with a surface grid from the outdoor side (see, for example, Patent Documents 1 and 2). However, some conventional surface grids are designed so that the body cannot enter, but the grid spacing is wide, and the surface grid itself can be mounted at a certain distance from the outer wall or opening. There may be a gap between the lattice and the window to allow access from the top, bottom, left, and right to fingers, and various tools such as bars, screwdrivers, and pliers. If the window provided with such a face lattice is unlocked and opened, the above tool can be inserted through the gap to unlock other openings, or dangerous materials can be inserted. There is a worry to do. As described above, even if the conventional surface lattice is called crime prevention, it is assumed that the window is locked. Therefore, when the lock is forgotten, the crime prevention performance is remarkably inferior.

  In order to solve such a problem, Patent Document 3 discloses a configuration in which a punching metal is directly fitted into an opening of a building. In this configuration, the punching metal is formed in the same size as the opening and fitted into the opening, and an L-shaped angle is provided on the peripheral edge of the punching metal, and the punching metal is attached to the opening by the angle member. The structure attached to a frame is disclosed.

JP 2006-336438 A JP 2006-37451 A JP 2003-148060 A

  However, in the surface lattice of the configuration, it is necessary to form the punching metal in the same size as the size of the opening, and it is difficult to correspond to the opening having a plurality of sizes. If not formed very accurately, a gap may be formed between the opening and the punching metal. If a gap occurs in this way, a security function can be used, such as inserting a screwdriver into the gap to destroy the punching metal and opening the opening, or revealing such a possibility. And may not have sufficient deterrence. Also, even when the punching metal is formed in an accurate size, a screwdriver or the like is inserted into the gap between the punching metal and the opening if the punching metal is configured to be fastened by an angle member as in the prior art. The tip of the screwdriver or the like can be inserted between the angle and the frame of the opening, and the lever principle can be applied using the point as a fulcrum. May lead to

  Therefore, the present invention can suppress insertion of tools such as drivers as much as possible and suppress annoying acts such as destruction by the tools, or can make the destruction work by the tools as long as possible, and An object of the present invention is to provide a security screen device that can visually recognize the difficulty of the work.

(1) In order to solve the above problems, the present invention provides:
A security screen device for covering an opening provided in an outer wall of a building from the outdoor side,
A face material provided to face the opening;
A frame that is interposed between the face material and the opening and holds the face material in front of the opening;
With
The frame body has a backing portion that is in surface contact with the peripheral edge portion of the back surface of the face material, and rises from the backing portion with a height corresponding to the thickness of the face material to the edge portion of the face material. A streaky fin facing or abutting with a slight gap,
The face material is fixed to the backing portion in a state of being surrounded by the fin.

  According to this, since the peripheral edge portion of the face material is fixed to the backing portion of the frame body, it is possible to avoid as much as possible annoying acts such as insertion or destruction of a tool such as a screwdriver by another person. Further, the frame body is provided with streak-like fins having a height corresponding to the thickness of the face material, and by attaching the face material to the frame body, the face material is surrounded by the fins. The seam (gap) between the backing portion of the frame and the face material is blocked by the fins, thereby preventing the tool from being inserted into the seam. Further, a seam (gap) between the fin and the face material becomes apparent, but the depth of the seam is substantially the thickness of the upper surface material, and the base end portion of the fin is a backing portion. Therefore, even if the end edge portion of the tip of the tool can be inserted slightly, further insertion of the tool is prevented by the backing portion. For this reason, even if the seam becomes obvious, it is not possible to insert a tool deeply into the seam, thereby ensuring a sufficient fulcrum (and a point of action) for the lever principle to work. Therefore, it is possible to prevent the tool from being opened. In addition, the lever principle cannot be fully applied in this way, so that the time required to pry up is also long.

  (2) It is preferable that the face material is formed of a flat punching metal.

  A face material (for example, a porous plate) formed of a punching metal is excellent in crime prevention because its opening hole is generally minimal. In addition, the face material is easy to ensure visibility and breathability from residents and the like.

  (3) In the security screen device, the fin includes a rising portion having a height corresponding to the thickness of the face material, and a flange portion protruding from the rising portion toward the surface of the face material, the flange portion Is extended in a state of facing the backing portion to form a deep groove portion having the rising portion as a bottom portion, and a peripheral portion of the face material is inserted into the deep groove portion, and the flange portion and the backing portion are It is preferable that the peripheral portion of the face member is fixed to the backing portion by fastening with a fastening member.

  According to the frame provided with such fins, it is difficult to form a gap between the frame and the peripheral portion of the face material, and it is possible to further improve crime prevention. Moreover, it can also be set as the payment which does not require fillers, such as packing.

  (4) In the security screen device, the fin includes a rising portion having a height corresponding to the thickness of the face material, and a flange portion slightly protruding from the rising portion toward the surface of the face material, It is also preferable that a shallow groove portion having the rising portion as a bottom portion is formed between the flange portion and the backing portion, and the peripheral portion of the face material is inserted into the shallow groove portion to hold the face material.

  By adopting relatively small fins in this way, it is possible to construct a design in which the flatness of the face material is emphasized while ensuring crime prevention.

  (5) In the security screen device, it is preferable that the frame is in close contact with the frame mounting surface of the outer wall via a packing member.

  In general, the attachment surface to the wall surface of the frame body is somewhat uneven (pretend), but according to the present invention, the elastic packing member is closely attached to the attachment surface. The degree can be improved.

  (6) In the security screen device, it is preferable that a cut surface that avoids interference with an adjacent frame is formed at an end of the frame. According to this, it is possible to avoid the formation of a gap by eliminating the overlap between adjacent frames and making them flush with each other.

  According to the present invention, insertion of a tool such as a driver can be avoided as much as possible to suppress annoying acts such as destruction by the tool, and the destruction work by the tool can be made as long as possible. The difficulty of the work can be visually recognized.

  Hereinafter, embodiments of a security screen device according to the present invention will be described in detail with reference to the drawings.

<First Embodiment>
The security screen device 1 according to the present invention is a device that covers an opening (for example, a bathroom window) 12 provided on an outer wall 11 of a building 10 from the outdoor side. The security screen device 1 of the present embodiment includes a porous plate (face material) 2 and a frame body 3 that holds the porous plate (face material) 2.

  The frame 3 is a member that is interposed between the porous plate 2 and the opening 12 and holds the porous plate 2 in front of the opening 12 (see FIGS. 1 and 2). The frame 3 is attached so as to be in close contact with the frame attachment surface 11a of the outer wall 11 (for example, the frame (window frame) of the opening 12). In this embodiment, each side of the rectangular porous plate 2 is supported by four frame bodies 3 arranged on the top, bottom, left, and right. The frame body 3 of the present embodiment includes a backing portion 31 and fins 32. The backing portion 31 of the frame 3 is formed as a portion that is in surface contact with the peripheral portion (indicated by reference numeral 21) on the back surface of the porous plate 2.

  The frame body 3 in the present embodiment has a long cylindrical shape. The corners of each frame 3 are abutted with each other as an oblique cut surface (for example, 45 ° cut) so as not to interfere with the adjacent frame 3 (see FIG. 4). Further, the adjacent frame bodies 3 are fastened together directly or using an L-shaped angle member 6 or the like.

  In the frame 3, the contact surface 36 of the outer wall 11 with the frame attachment surface 11 a is flat and is in close contact with the frame attachment surface 11 a without any gap (see FIG. 3). The member (fixing member 7) for fixing the frame 3 to the outer wall 11 may be a piece-like one (partially formed) that supports a part of the frame 3, The thing of the elongate shape extended along a elongate direction may be sufficient. If the fixing member 7 has a long shape surrounding the entire circumference of the frame 3, the function of eliminating the gap between the frame (outer wall 11) of the building 10 and the frame 3 can also be achieved. Although the method of attaching the fixing member 7 is not particularly limited, it is preferably attached from the indoor side of the building 10 from the viewpoint of preventing the fixing member 7 from being removed from the outside (see FIGS. 1 and 2). In such a case, since the fixing member 7 cannot be seen from the outside and cannot be contacted, the crime prevention property is also enhanced in that respect. When the fixing member 7 is attached, for example, a plate-like portion for eliminating a gap between the window frame and the screen can be used.

  The fins 32 of the frame 3 are formed so as to stand up from the backing portion 31 and to face or abut with a small gap (indicated by reference numeral 22) of the porous plate 2 with a slight gap. The rising width of the fins 32 is preferably about the thickness of the porous plate 2. The porous plate 2 described above is attached to the fin 32 in a state where the periphery (the small-mouthed portion 22) is surrounded and fixed to the backing portion 31 (see FIG. 1 and the like).

  The porous plate 2 is provided as an example of a face material facing the opening 12 of the outer wall 11. For example, the hole (see reference numeral 23 in FIG. 6) of the porous plate 2 is preferably a small one having a circular shape having a diameter of about 1.5 mm to 2 mm or a large number of comparable polygons. According to such a hole 23, pests such as mosquitoes can be prevented from entering from the outside. Further, if the aperture ratio of the hole 23 formed in the porous plate 2 is, for example, between 40% and 60%, the ventilation and visibility through the hole 23 are maintained while maintaining the strength of the porous plate 2. It is preferable in that it is easy to keep. In the porous plate 2, there are no through holes other than the holes 23.

  Moreover, the shape and material of the porous plate 2 are not particularly limited, but it is preferable that the surface is not bent, uneven, or undulated. According to such a porous plate 2, storage before assembling is easy, and the storage volume is reduced, so that the cost can be suppressed. In addition, when the bending process is performed, the coating of the bent portion may be peeled off and repair may be necessary. However, according to the porous plate 2 having no bending on the surface, this is not the case. As such a porous plate 2, a rectangular punching metal etc. are employable, for example. The porous plate 2 made of punched metal is excellent in crime prevention because the holes 23 are generally minimal, and it is easy to ensure visibility and breathability from residents and the like.

  The porous plate 2 of the present embodiment is attached to the frame body 3 by fastening members such as screws 4 from the finding (front) side (see FIGS. 1 and 2). As the screw 4, a length that does not penetrate from the opposite side of the frame 3 is used.

  In addition, when the finding (horizontal width) of the opening 12 is particularly long, the middle frame 3A can be added to the frame 3 (see FIG. 2). In this case, a porous plate 2 divided into left and right or up and down can be used. Each porous plate 2 is preferably attached to the inner frame 3A with screws 4 (see FIG. 2). Such an inner frame 3 </ b> A may not be in close contact with the outer wall 11 of the building 10. The middle frame 3A can be used as a joint when the size of one of the porous plates 2 is limited due to manufacturing or the strength of the plate and is smaller than the entire security screen device 1. Yes, it is convenient.

  According to the security screen device 1 of the present embodiment, since the peripheral portion 21 of the porous plate 2 is fixed to the backing portion 31 of the frame 3, the tool can be inserted into the gap by another person, Annoying acts such as destruction can be avoided. Temporarily, in the case of a general plane lattice, there is an incident that is cut by a bolt clipper, but in the case of the security screen device 1 of the present embodiment, there is no gap, so the bolt clipper cannot be sandwiched. Security is high. In short, “crime-proof” not only prevents intruders, but also intrusions of tools (such as traps that can open other openings or even be threatened from outside by dangerous materials) In other words, the security screen device 1 is expected to improve the crime prevention performance by exerting a deterrent that does not reach various nuisance acts. it can.

  Further, the frame 3 is provided with fins 32 that surround (enclose) the porous plate 2 and close the joint (gap) between the backing portion 31 of the frame 3 and the porous plate 2. Tool insertion into the seam is prevented. Further, regarding the joint (gap) that can be manifested between the fin 32 and the porous plate 2, the depth of the joint is substantially the thickness of the porous plate 2, and the base end of the fin 32 is also provided. Since the portion is connected to the backing portion 31, even if the end edge portion of the tip portion of the tool can be slightly inserted, further insertion of the tool can be prevented. For this reason, even if the seam becomes obvious, it is not possible to insert a tool deeply into the seam, thereby ensuring a sufficient fulcrum (and a point of action) for the lever principle to work. Therefore, it is possible to prevent the tool from being opened. In addition, since the principle of the lever cannot be sufficiently applied in this way, it takes a long time even if it is pry open.

  Further, when the corner portions of the frame 3 are faced to each other, a seam portion is formed between them. However, since the width of the fin 32 is small in the security screen device 1 of the present embodiment, it can be visually recognized from the front. The joint portion is only a portion corresponding to the width of the fin 32, and the other joint portion is covered with the porous plate 2 and cannot be seen. Thus, in this embodiment, since the width | variety of the fin 32 is made remarkably small, it is hard to put a tool in the first place, and even if it puts, it is hard to make an insulator effective. Moreover, since it can visually recognize that the width | variety of the fin 32 is small, it is hard to produce the motive for putting a tool into a joint for others.

  Furthermore, since the crime prevention screen device 1 of the present embodiment employs the porous plate 2, it is excellent in crime prevention performance in this respect as well as excellent invasion prevention performance of pests such as mosquitoes. Moreover, since the security line is the porous plate 2, it is not necessary to provide the sash or glass with security, forgetting to lock, going out with the window open, or sleeping with the window open. Even if it is safe, a screen door is unnecessary. Also, indoor pets such as cats may destroy or damage the normal screen door when the window is opened, but the porous plate cannot be destroyed, so there is no such concern, and the window There is no worry of pets running away even in ventilated ventilation.

<Second Embodiment>
The fin 32 in the present embodiment includes a rising portion 32a and a flange portion 32b that protrudes toward the surface of the porous plate 2 so as to be bent from the rising portion 32a (see FIGS. 5 and 6). The fins 32 are formed so as to rise from the backing portion 31 and to face or contact each other with a slight gap at a small edge portion (indicated by reference numeral 22) of the porous plate 2.

  In this way, the flange portion 32b extends in a state of facing the backing portion 31, so that it is a finding portion (near side) of the frame body 3, and the backing portion 31 of the frame body 3 and the fins 32 on the surface side. A deep groove portion (insertion groove) 33 having a rising portion 32a as a bottom portion is formed therebetween. In the present embodiment, the peripheral edge portion 21 of the porous plate 2 is inserted into the deep groove portion 33, and the flange portion 32 b and the backing portion 31 are fastened with screws (fastening members) 4, so that the peripheral edge portion 21 of the porous plate 2. Is fixed to the backing portion 31. The rising width of the fin 32 is preferably equivalent to the thickness of the porous plate 2. From such a fin 32, the porous plate 2 is attached in a state of being fixed to the backing portion 31 in a state of surrounding the porous plate 2.

  In the present embodiment, the peripheral edge portion 21 of the porous plate 2 is fastened to the backing portion 31 with a screw (for example, a one-way screw or a security screw) 4. In this embodiment, since the backing portion 31 of the frame 3 is a surface, the screws 4 are easily provided. Moreover, a double-sided tape or the like can be applied to the backing portion 31 as an auxiliary member for preventing the peeling of the porous plate 2 to increase the strength. In addition, the fin 32 of this embodiment is attached so that it may contact | connect the finding part (surface which looks forward when the said member is seen from the front) of the frame 3, Comprising: It is not attached to the side surface of the member, that is, the surface in the depth direction (see FIG. 2 and the like).

  Generally, if a flat security surface member is only inserted into the frame 3, the security surface material may be distorted and come out of the frame 3 when a large force is applied to the security surface material itself. There is. In this respect, in the security screen device 1 of the present embodiment, the periphery of one porous plate 2 is surrounded by a frame body 3, and is fixed to the frame body 3 with screws (one-way screws, security screws, etc.) 4. Therefore, when a force is applied to the porous plate 2, the porous plate 2 itself may be distorted, but it is difficult to escape from the frame 3. Further, the porous plate 2 reinforces the frame 3 in strength, and increases the strength of the security screen device 1 as a whole.

  In general, a normal frame that holds a flat crime prevention face material often has a deep insertion portion so that the flat plate is difficult to come off. However, in such a case, in order to insert the security face material without friction, the width of the gap of the insertion part must be taken to some extent, so that the width of the insertion part and the remaining gap of the porous plate 2 are reduced. In order to solve the problem and prevent the security surface material from wobbling, it must be fixed with beads or pressed with packing. However, since the packing and bead are made of an elastic body, a tool such as a screwdriver or a bar is inserted therein, and there is a concern that a flat plate having a lower strength than the frame body 3 may be broken due to the principle of lever. In this respect, in the security screen device 1 of the present embodiment, a gap is formed between the frame body 3 and the peripheral edge portion 21 of the porous plate 2 by the frame body 3 provided with the fins 32 having the above-described shape. Since it becomes difficult, it can also be set as the packing which does not require packing materials, such as packing.

<Third Embodiment>
The fin 32 in the present embodiment includes a rising portion 32 a having a height corresponding to the thickness of the porous plate 2 and a flange portion 32 c that slightly protrudes from the rising portion 32 a toward the surface of the porous plate 2. Yes. In the present embodiment, a shallow groove portion 34 having a rising portion 32 a as a bottom portion is formed between the flange portion 32 and the backing portion 31, and the peripheral edge portion 21 of the porous plate 2 is inserted into the shallow groove portion 34. The porous plate 2 is held (see FIGS. 7 and 9). FIG. 9 shows the frame 3 provided in the middle.

  The frame 3 is composed of, for example, four frame members on the upper, lower, left, and right sides which are faced to each other at the end surfaces cut at 45 °, or at both ends of an L-shaped member forming a corner. However, in some cases, a gap is generated between the flange portions of the frame member to be abutted or between the frame member and the L-shaped angle member between the joint portions formed by the abutment. There is a risk that tools or the like can be easily inserted into the gap. In this respect, according to the security screen device 1 of the present embodiment, since the collar portions 32c that protrude slightly are provided, the length of the gap between the collar portions 32c is slight (see FIG. 8). It becomes difficult to insert tools. Further, according to the security screen device 1 of the present embodiment, since there is no gap for inserting the tool at first glance, it is possible to suppress the motivation to destroy the security screen device 1 in the first place (FIG. 10). reference). Furthermore, in the present embodiment, by adopting relatively small fins 32, it is possible to construct a design in which the planarity of the porous plate 2 is emphasized while ensuring crime prevention.

  In addition, the protrusion amount of the collar part 32c from the upper end part of the rising part 32a is equivalent to the thickness of the porous plate 2, for example. According to the configuration of the flange portion 32c, it is difficult to insert a tool or the like into the shallow groove portion, or even if it is inserted, it is difficult to exert the action of the lever, and further, it is difficult to apply a moment from the tool to the fin 32. The rigidity is improved. Moreover, when the hole 23 and the real part (parts other than the hole 23) of the punching metal are continuously jagged, or from the relationship with the construction error, from one end to the other end of the frame 3 In the case where the fin 32 is gradually separated from the rising portion 32a, the flange portion 32c has an effect that the peripheral portion 21 of the porous plate 2 can be hidden.

<Fourth Embodiment>
In this embodiment, the packing member 5 is interposed between the frame body attachment surface 11a of the outer wall 11 and the frame body 3, and the frame body 3 is brought into close contact with the packing member 5 (FIGS. 11 and 11). 12). It is also preferable to provide a packing housing groove 35 in the frame body 3 that can absorb the thickness when the packing member 5 is compressed and contracted so that there is no gap between the frame body 3 and the frame body 3. In general, the frame mounting surface 11a of the outer wall 11 is somewhat uneven, but in the security screen device 1 of the present embodiment, the degree of adhesion is provided by providing the elastic packing member 5 on the contact surface. Can be improved. Further, if the degree of adhesion is improved in this way, it also leads to strengthening prevention of invading pests such as mosquitoes. Furthermore, by bringing the frame 3 into close contact with the frame attachment surface 11a of the outer wall 11 via the packing member 5, there is an advantage that dirt on the wall surface of the outer wall 11 does not enter the opening 12.

  The above-described embodiment is an example of a preferred embodiment of the present invention, but is not limited thereto, and various modifications can be made without departing from the scope of the present invention. For example, in a dwelling unit of a housing complex, a window on the side of the common corridor is in the immediate vicinity of the passage, and there is a risk that the privacy of the dwelling unit resident is infringed. Also, you might get thrown in by mischief because you get your hands right from the aisle. Therefore, even if it is a precious window, it can be considered that a situation in which ventilation and ventilation cannot be performed in a closed state can occur. By installing the above-described crime prevention screen device 1 in such a window, even if the window is in an open state, the crime prevention property is high, and the inside can be made difficult to see by the porous plate 2, By making the bottom of the window more than the height of a person's eyes, you can prevent it from being looked into. In short, in the above-described embodiment, a bathroom window is shown as an example of the opening 12 of the building 10, but this is only an example, and in addition, a high window provided on the outer wall facing the common corridor in this way, etc. The present invention can be applied to various openings 12.

  The present invention is suitable for application to a security screen device that covers an opening provided on an outer wall of a building from the outdoor side.
