Description

  The present invention relates to a security door suitable as a security door for an apartment house such as an apartment.

For the purpose of crime prevention and the like, various technologies for enhancing the crime prevention effect by installing double doors in front of the entrance of a house have been proposed.
For example, Patent Document 1 discloses an auxiliary door such as an entrance, and the auxiliary door is provided adjacent to a normal door so that the outside can be visually recognized from a living room. According to the technique described in this document, an auxiliary door is added in addition to a normal door, and the auxiliary door can be visually recognized from the outside, so that the crime prevention effect can be enhanced.

  For example, Patent Document 2 discloses a front entrance fence installed in front of a front door of a detached house. This front fence has a plurality of vertical bars arranged to form a fence, and adjacent vertical bars are connected by a horizontal pantograph mechanism. According to the technique described in this document, the crime prevention effect can be enhanced by the front entrance fence installed in front of the house entrance. And since this front fence can be expanded and contracted by a horizontal pantograph mechanism, it can be installed according to the frontage width even if the frontage width is different.

Further, for example, in Patent Document 3, the doorway is a double door, the second door is not opened unless the first door is closed, and the space between the two doors is also a windshield, for example. In this way, it is configured as a space for about one person to enter, thereby disclosing a technique for eliminating intruders.

  Here, for example, in the technique described in Patent Document 1, although the crime prevention effect can be expected when in the living room, the auxiliary door is provided adjacent to the normal door, so when entering the living room side from the outside. You cannot enter the room unless you open the two doors at the same time. For this reason, there are crimes (hereinafter referred to as “intrusion crimes”), such as following the person who goes home or ambushing to come home, and the person who comes home enters the moment the door is opened and robs or rapes. It cannot be dealt with.

  On the other hand, in the technique described in Patent Document 2, for example, the front fence can secure a space for a person to enter between the entrance door using, for example, an entrance porch. Can also be dealt with. Similarly, in the technology described in Patent Document 3, the space between the two doors is configured as a space for one person to enter, and this eliminates intruders, so that it can also deal with intrusion crimes. Can do.

  However, the technique described in Patent Document 2 is a technique that assumes an entrance in a detached house, and an outside door is installed by occupying an external space using an entrance porch or the like. Therefore, even if the technology described in this document is used as a security door for apartment buildings such as condominiums at the entrance of a dedicated space of each household, it always occupies the shared space outside the entrance and has the original convenience of the shared space. It will fall. Therefore, it is difficult to adopt the technique described in Patent Document 2 as it is for a security door of an apartment house.

  In addition, the technique described in Patent Document 3 is the same in this respect, and although it can be adopted for a shared entrance such as an apartment, a shared space is required when this is to be adopted for an individual entrance of each household. In order to install without using, for example, it is necessary to install two doors in a dedicated space of each household and provide a space for about one person in the dedicated space. Therefore, the space on the living room side is subject to that restriction. Moreover, even if it is going to provide the same structure in the shared space side, the outer side door of two doors and the side wall for supporting the door will always occupy the shared space. For this reason, as with the technique described in Patent Document 2, the original convenience of the common space is lowered, so that it is difficult to adopt as a security door for each door in an apartment house such as an apartment, and there is still room for improvement.

  Therefore, the present invention has been made paying attention to such problems, and a security door that can cope with an intrusion crime by installing double doors, etc. Suitable for use as a door, even if it is used in apartment houses such as condominiums, crime prevention for apartment buildings that can deal with intrusion crimes without restricting the exclusive space of each household and always occupying the common space The purpose is to provide a door.

The crime prevention door for an apartment house is used in an apartment house such as a condominium, and as shown in FIG. 1, has an entrance door 1 and an auxiliary door 2 arranged on the shared space C side. Has been.
Specifically, as shown in FIG. 2, the entrance door 1 is a first door that partitions between the private space P and the common space C of each household, and has a lock and a dedicated door like a normal entrance door. The key can be locked and unlocked. On the other hand, the auxiliary door 2 is a second door disposed on the shared space C side outside the entrance door 1.

  The auxiliary door 2 has a lock 5 which is disposed on the wall surface H on which the entrance door 1 is provided and can be locked. In the example of the present embodiment, the height of the auxiliary door 2 is formed to be substantially the same as the height of the entrance door 1, and the left auxiliary door 2 </ b> L separated from the center to the left and right and the right The auxiliary door 2R is configured to open and close like a double door. Further, the left and right left auxiliary doors 2L and the right auxiliary door 2R can be folded so as to assume the retracted posture K shown in FIG. 2 (a) and the surrounding posture T shown in FIG. 2 (c). It has a configured deformation structure.

  More specifically, the deformation structure of the auxiliary door 2 is configured such that each of the left auxiliary door 2L and the right auxiliary door 2R has a plurality of glass panels 3 made of a glass material that can visually recognize the opposite side. . In the example of the present embodiment, there are five rectangular tempered glass panels 3 made of tempered glass. The plurality of glass panels 3 are connected to each other by a plurality of hinges 4. The plurality of hinges 4 are provided between the adjacent glass panels 3 and spaced apart from each other in the vertical direction so that the plurality of glass panels 3 can be rotated within a predetermined rotation range. It is pivotally supported. The left and right left auxiliary doors 2L and 2R have a glass panel 3 that is positioned closest to the wall surface H among the plurality of glass panels 3 constituting the left and right auxiliary doors 2R and rotates to the wall surface H by a fixing hinge 4K. Connected as possible.

The glass panel 3 located at the opposite end is fitted with the left and right paired locks 5 at a substantially central part in the vertical direction. Locking is performed by mutually locking the locks 5 of the 2L and the right auxiliary door 2R.
The deformed structure of the auxiliary door 2 is constituted by the above-described configuration. As shown in FIG. 2A, the auxiliary door 2 separates the left and right left auxiliary doors 2L and the right auxiliary door 2R from side to side, thereby separating the front door 1 The storage posture K stored along the wall surface H provided with the entrance door 1 is taken by extending the entrance door 1 to the left and right along the wall surface H provided with. The auxiliary door 2 is stored in a position that does not hinder the use of other households in the shared space C as shown in FIG.

In the enclosed space R, a security buzzer 9 is installed as a warning device at a position where a resident or the like can operate from within the space R. Accordingly, an alarm is issued by pressing the security buzzer 9.

Next, the operation and effect of the security door 10 will be described.
As described above, since the security door 10 includes an auxiliary door 2 in addition to the lockable entrance door 1 that partitions between the dedicated space P and the common space C of each household, for example, the above-mentioned Patent Document 1 The crime prevention effect can be heightened similarly to the technique of thru | or 3.
According to the security door 10, the auxiliary door 2 is disposed with respect to the wall surface H on which the entrance door 1 is provided, and the surrounding posture T shown in FIG. In the Go posture T, a range in which at least one person can enter the space on the side of the shared space C adjacent to the entrance door 1 is provided. Since the enclosed space R can be viewed from the shared space C side, for example, even if there is an intruder who plans the intrusion crime described above, the intruder is surely excluded. Can do.

  That is, when this security door 10 is used, for example, when a resident or the like enters the private space P from the shared space C side, the resident or the like places the auxiliary door 2 in the surrounding posture T in the defined space R to be surrounded. After that, the auxiliary door 2 is locked by hooking a pair of locks 5 to each other, and then the entrance door 1 is opened to enter the exclusive space P, and from the exclusive space P to the shared space C side. If the entrance door 1 is locked after exiting from the entrance space 1 surrounded by the entrance door 1, and then the lock 5 of the auxiliary door 2 is unlocked and placed in the retracted position K, it will be pushed in. Even if there are intruders who plan crimes, they can be surely excluded.

  Further, the security door 10 is configured such that the deformation structure of the auxiliary door 2 is stored along the wall surface H provided with the entrance door 1 in the storage posture K. It can be configured to store up to a position that does not hinder the use of other households. Therefore, even if it is used for an apartment house such as an apartment, it can be used without restricting the dedicated space P of each household and without always occupying the shared space C. Accordingly, it is possible to suppress a decrease in convenience of the shared space.

Moreover, according to this security door 10, the deformation | transformation structure of the auxiliary door 2 is pivotally supported so that the several glass panel 3 which consists of a glass material which can visually recognize the other side, and these several glass panels 3 can be rotated mutually. Therefore, it is suitable as a deformed structure configured to take the postures of the surrounding posture T and the retracted posture K as described above.
Moreover, according to this security door 10, since the security buzzer 9 which can be operated from the enclosed space R is provided, when it is in the enclosed space R, it should be mentioned above. Even if an intruder who plans an intrusion crime tries to intrude from the outside of the auxiliary door 2, an alarm can be issued with the crime prevention buzzer 9. Therefore, intruders can be more reliably excluded.

As described above, according to the security door 10, even if it is used in an apartment house such as an apartment, it is possible to cope with an intrusion crime without restricting the exclusive space of each household and always occupying the common space. is there.
The security door according to the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
For example, in the above embodiment, the left auxiliary door 2L and the right auxiliary door 2R on the left and right sides respectively connect the five glass panels 3 to each other by the hinges 4, and in the surrounding posture T, the plan view is substantially semicircular. Although the example in which the defining space R is formed in a curved form has been described, the present invention is not limited to this, and the auxiliary door 2 can be a single door as long as it has a deformable structure that can be in the Go posture T and the retracted posture K. Moreover, the configuration of various forms can be adopted for the forms of the surrounding posture T and the retracted posture K.

A specific modification (first modification) is shown in FIG.
As shown in the figure, the first modification is different from the first embodiment described above in the number of the plurality of glass panels 3 and the forms of the surrounding posture T and the storing posture K.
That is, in the first modification, each of the left auxiliary door 2L and the right auxiliary door 2R is configured to have two glass panels 3. The plurality of hinges 4 connecting the two right and left glass panels 3 use hinges whose predetermined rotation range is limited to a range of 0 to 90 °.

And in this 1st modification, as shown to the same figure (a), in the storage attitude | position K, each of the left auxiliary door 2L and the right auxiliary door 2R is two glass panels 3 in the storing attitude | position K. Are stacked in a direction facing the wall surface H, and are stored along the wall surface H in the folded state in which they are stacked.
And as shown in the figure (b), when the glass panel 3 by this side of the auxiliary door 2 is pulled out, it will be rotated to the position opened at 90 degrees. Further, as shown in FIG. 5C, when the entire two glass panels 3 are rotated, the glass panel 3 connected to the wall surface H is also rotated to a position where the glass panel 3 opens at 90 °. At T, the definition space R is formed in a substantially rectangular shape in plan view. Therefore, even with such a configuration, the same operations and effects as those of the first embodiment are achieved.

  Further, for example, in the above-described embodiment, the auxiliary door 2 can be visually recognized from the shared space C side in the enclosed definition space R, and the plurality of glass panels 3 made of a glass material that can visually recognize the opposite side. However, the present invention is not limited to this, and various configurations can be adopted as long as the enclosed definition space R is visible from the shared space C side.

4 and 5 show a second modification.
As shown in FIG. 4, the security door 10 </ b> B according to the second modified example includes a plurality of auxiliary doors 2 that are second doors arranged with their axes up and down as shown in FIG. 4. And the connecting mechanism 14 for connecting the plurality of bars 13 so as to extend and contract in the horizontal direction. And the security door 10B of this 2nd modification is further provided with the guide rail 15 laid on the common corridor B in order to guide the expansion-contraction of the auxiliary door 2. As shown in FIG.
Here, the height of the auxiliary door 2 is formed to be substantially the same as the height of the entrance door 1, and is composed of a left auxiliary door 2L and a right auxiliary door 2R that are separated from the center to the left and right. This is the same as in the above embodiment.

  However, in the above-described embodiment, the left auxiliary door 2L and the right auxiliary door 2R are opened and closed like a double door. However, the auxiliary door 2 of the second modified example is an intermediate portion of the plurality of crosspieces 13. The upper and lower two places are connected by a connecting mechanism 14, and this connecting mechanism 14 is expanded and contracted by combining a plurality of links in a rhombus shape like a pantograph so as to move the plurality of bars 13 relative to each other in the horizontal direction. . Further, the guide rail 15 guides the lower end portions of the plurality of crosspieces 13 along a line that should surround the defining space R when the coupling mechanism 14 is expanded and contracted. In addition, the creeping 13S is provided on the upper part of each of the plurality of crosspieces 13. Even in such a configuration, the auxiliary door 2 of the second modification example has the respective postures of the retracted posture K shown in FIG. 5A and the surrounding posture T shown in FIG. be able to. Then, in the Go posture T, the extension of the connecting mechanism 14 that expands and contracts causes the adjacent crosses 13 to be separated from each other, so that the enclosed space R can be viewed from the shared space C side.

Next, FIGS. 6 and 7 show a third modification.
As shown in FIG. 6, the crime prevention door 10 </ b> C of the third modification has a plurality of auxiliary doors 2 as second doors arranged with their axes up and down, as shown in FIG. 6. This is different from the first embodiment in that the crosspiece 13 and the coupling mechanism 14 for connecting the plurality of crosspieces 13 so as to move relative to each other in the horizontal direction are configured.
Here, the security door 10C of the third modification is similar to the above embodiment in that it is composed of a left auxiliary door 2L and a right auxiliary door 2R separated from the center to the left and right. The height of 2 is different from the above-described embodiment and the above-described other modifications in that it is provided up to the height of the ceiling U of the shared space C.

  The plurality of crosspieces 13 extending to the height of the ceiling U are vertically moved by the guide rails 15 laid on the common corridor B and on the ceiling U in order to guide the expansion and contraction of the auxiliary door 2 of the third modification. It is slidably supported. Note that the third modified example also has a coupling mechanism 14 having the same configuration as the second modified example. However, the coupling mechanism 14 of the third modified example has both ends of a plurality of crosspieces 13 connected. In addition to being connected, it is provided at a position where it is built in the upper and lower guide rails 15, thereby refreshing the design of the appearance.

  The security door 10C according to the third modified example includes guide rails 15L and 15R in which the upper and lower guide rails 15 are separated from each other on the left and right. Each guide rail 15L, 15R has a curved portion 15m that supports and guides the top and bottom of the plurality of crosspieces 13 at a position where the surrounding posture T is to be taken. Moreover, it has the linear part 15s which supports and guides the upper and lower sides of the some cross | piece 13 along the wall surface H in which the entrance door 1 was provided in the position which should take the said storing attitude | position K. As shown in FIG. The curved portion 15m and the straight portion 15s are continuously and smoothly connected by the connecting portion 15r.

According to the third modified example, the auxiliary door 2 of the security door 10C is shown in the storage posture K shown in FIG. 7A and the FIG. 7C as in the above-described embodiment and other modified examples. Each of the Go postures T can be taken, and in the retracted posture K, the entire auxiliary door 2 is guided and supported along the straight portion 15s, so that the wall H on which the entrance door 1 is provided is provided. The posture stored along, for example, can reduce the amount of overhang in the direction facing the wall surface H, compared to the stored posture K in the second modification illustrated above (see FIG. 5A). . Therefore, it is more suitable for storing so that the shared space is not always occupied. In addition, if a door pocket is provided so as to cover the auxiliary door 2 at the position of the storage posture K, the appearance design can be further refined.
Moreover, although the deformation | transformation structure of the auxiliary door 2 mentioned above demonstrated in the example of the structure where a resident etc. open and close by hand, it is not limited to this, The deformation structure which concerns on this invention is automatic by drive devices, such as a motor. By opening and closing the switch, the postures of the Go posture and the retracted posture can be taken.

Specifically, for example, FIGS. 8 and 9 show a fourth modification.
In the security door 10D of the fourth modification, the auxiliary door 2 has a configuration similar to a so-called grill shutter. That is, as shown in FIG. 8, the auxiliary door 2 of the fourth modified example is a link that is a connecting mechanism that connects the pipe members 16 that are a plurality of bars and the pipe members 16 so that the pipe members 16 can be wound up in the horizontal direction. And a member 17. In addition, storage boxes 18 are attached to the wall surfaces to store the left and right auxiliary doors 2L and 2R individually on the left and right sides of the entrance door 1, and an electric winding device is built in the upper part thereof. The drive part 18a is arrange | positioned, respectively.

  And the switch (not shown) for driving the drive part 18a is provided in each of the position which can be operated in the defined space R of the wall surface H, and a living room. Further, each of the auxiliary doors 2L and 2R in the fourth modified example is shared by the plurality of pipe members extending to the height of the ceiling U in order to guide the auxiliary door 2 as in the third modified example. The upper and lower sides are supported so as to be slidable by guide rails 15 laid on the hallway B and the ceiling U, respectively.

As a result, the auxiliary doors 2L and 2R can be automatically wound and unwound as shown in FIGS. 9A to 9C by the winding device in the drive unit 18a.
That is, the auxiliary door 2 of the fourth modified example is in the retracted position K when it is stored in the wound state wound up to the maximum diameter in the storage box 18 in the wound state shown in FIG. At this time, the end 2b of the auxiliary door 2 is held by the opening slit 18s (see FIG. 8) of the storage box 18. Further, in the extended state shown in FIG. 9C, the end posture 2b of the left and right auxiliary doors 2 is positioned in contact with each other and takes the above-described surrounding posture T. In addition, the winding part in the storage box 18 at this time becomes the minimum diameter.

According to the security door 10D of the fourth modified example, the left and right auxiliary doors 2 are disposed with respect to the wall surface H on which the entrance door 1 is provided, and the surrounding posture T and Because it has a deformed structure configured to take each of the storage postures K, even if it is used in an apartment house such as a condominium, it does not restrict the dedicated space of each household and always occupies the common space It is also possible to deal with intrusion crimes.
In particular, according to the security door 10D of the fourth modified example, the deformed structure of the auxiliary door 2 is configured to automatically open and close by a driving device such as a motor, and therefore always occupies a common space. It is more suitable for storing so that it does not occur. Further, since the storage box 18 (door bag) is provided so as to cover the auxiliary door 2 at the position of the storage posture K, the appearance design can be further refined.
