【発明が解決しようとする課題】
特許文献1,2に開示されたシャッターは、シャッターカーテンを閉じ状態で室内側から施錠できるが、室外からバールを用いて故意にこじ開けることで錠が解錠される恐れがある。
例えば、シャッター枠の下枠と座板との間にバールを差し込み、無理にこじることで座板を簡単に上方に変位させて錠を短時間に解錠できる。つまり、座板自体は上方に変位し易く、その座板を所定量以上に上方に変位すると錠が破損等して解錠状態となる。
このように、短時間に錠が解錠されることは防犯上好ましくない。
特に、サッシ窓の室外側に雨戸として取付けたシャッターの場合には、その下枠が地面よりも高い位置であり、バールをこじる大きなスペースが存在するので、バールを用いてこじり易く、好ましくない。
【0005】
本発明は、前述の課題に鑑みなされたものであって、その目的は、バールを用いて無理にこじることで簡単に座板が斜め室外側上方に向けて所定量以上に変位することを防止できるようにしたシャッターを提供することである。
【0006】
【課題を解決するための手段】
第1の発明は、シャッター枠に沿ってシャッターカーテンを昇降してシャッター枠を開閉するシャッターにおいて、
前記シャッター枠の下枠に、前記シャッターカーテンが閉じ状態において、その座板の斜め室外側上方への変位量を規制し、かつ真直ぐ上方への変位は規制しない受け部材を取付けたことを特徴とするシャッターである。
【0007】
第2の発明は、第1の発明において座板に座板補強材を取付け、この座板補強材と受け部材が係止して座板の斜め室外側上方への変位量を規制するようにしたシャッターである。
【0008】
【作 用】
第1の発明によれば、室外から故意にバールを用いて座板をこじった場合に、その座板の斜め室外側上方に向けて簡単に変位する変位量が受け部材で規制され、それ以上は変位し難くなるから、故意にバールを用いて座板を無理にこじることで、その座板を簡単に上方に向けて所定量以上に変位することを防止できる。
よって、室外から故意にバールを用いて座板をこじって所定量以上上方に変位して錠を解錠状態とするのに時間がかかり、防犯上好ましいシャッターである。
また、受け部材は座板の真直ぐ上方への変位は規制しないので、シャッターカーテンを通常に開閉する場合に何ら影響しない。
【0009】
第2の発明によれば、座板補強材を取付けたことで座板が補強され、その座板の斜め室外側上方への所定量以上の変位を強固に防止できる。
【0010】
【発明の実施の形態】
図1に示すように、シャッター枠1と、このシャッター枠1の上部に設けた巻き取り繰り出し部2と、この巻き取り繰り出し部2で巻き取り、繰り出しされるシャッターカーテン3がシャッターの基本構成である。
すなわち、シャッターはシャッター枠1に沿ってシャッターカーテン3を昇降してシャッター枠1を開放、閉塞するものである。
前記シャッター枠1は、上枠10と下枠11と左右の縦枠12を有し、その左右の縦枠12はシャッターカーテン3を昇降自在にガイドするガイド部、例えばガイドレール13を備えている。
前記巻き取り繰り出し部2は、巻取りドラム20と、この巻取りドラム20を収納したシャッターボックス21を備え、そのシャッターボックス21は上面板22と左右の側面板23と前面カバー24で構成され、その前面カバー24は開閉自在で、かつこの前面カバー24の下部室内側部と上枠10の室外側部との間にシャッターカーテン3が出入りする開口部25が形成してある。
前記シャッターカーテン3は複数のスラット30を連結し、その最下部のスラット30に座板31を取付けたもので、その最上部のスラット30が巻取りドラム20に連結される。
【0011】
前述したシャッターにおいては、シャッターカーテン3を全閉した状態で、その座板31と下枠11との間に室外からバールを差し込み、無理にこじることで座板31が斜め室外側上方に向けて簡単に変位するから、座板31を所定量以上変位させて錠を解錠状態とするのに時間がかからず、短時間に解錠状態にでき、防犯上好ましくない。
【0012】
前記下枠11には受け部材40が取付けてある。この受け部材40は、シャッターカーテン3が閉じ状態において座板31の斜め室外側上方への変位量を規制し、真直ぐ上方への変位は規制しないものである。つまり、座板31が斜め室外側上方に若干変位すると座板31が受け部材40に係止し、それよりも上方への変位を規制する。この受け部材40は座板31の真直ぐ上方への変位は規制しないので、シャッターカーテン3の通常開閉時には邪魔にならず、何ら影響しない。
具体的には、受け部材40は取付片41と鉤片42を備え、その取付片41を下枠11の室外側寄り上面にビス43で固着して取付けられ、その鉤片42は室内側に向かう係止片42aを備えている。好ましくは、下枠11の室外側寄り下面に裏板44を設け、この裏板44にビス43を螺合して固着している。
前記座板31は、本体32の室内側面32aに鉤形片33を一体的に設けると共に、長手方向両端面に巻き込み防止ストッパ34を取付けたもので、座板補強材35が取付けてある。例えば、前記鉤形片33に座板補強材35がビス36で固着してある。
この座板補強材35が受け部材40に係止するようにしてある。
例えば、前記座板補強材35は、室外側に向かう鉤片35aを備え、通常状態では鉤片35aが受け部材40の鉤片42の係止片42aよりも室内側寄りで、座板31は上下に移動でき、前述のように座板31の真直ぐ上方への変位を規制しない。
そして、図2に仮想線で示すようにバールaを用いて前述のように座板31を斜め室外側上方に若干変位すると、図2に示すように鉤片35aが受け部材40の係止片42aに係止して座板31がそれよりも上方に簡単に変位することを防止する。この時、錠は破損等せずに施錠状態のままである。
よって、バールを用いてこじることで座板31を斜め室外側上方へ簡単に変位できる変位量を規制することができ、座板31をそれ以上に斜め室外側上方に変位するのは大変で時間がかかる。
【0013】
このようであるから、バールを用いて座板31を無理にこじることで座板31を、錠が破損等して解錠状態となるまで上方に変位(つまり、所定量以上に上方に変位)するには時間がかかり、防犯上好ましいシャッターである。
【0014】
【発明の効果】
請求項1に係る発明によれば、室外から故意にバールを用いて座板をこじった場合に、その座板の斜め室外側上方に向けて簡単に変位する変位量が受け部材で規制され、それ以上は変位し難くなるから、故意にバールを用いて座板を無理にこじることで、その座板を簡単に上方に向けて所定量以上に変位することを防止できる。
よって、室外から故意にバールを用いて座板をこじって所定量以上上方に変位して錠を解錠状態とするのに時間がかかり、防犯上好ましいシャッターである。
また、受け部材は座板の真直ぐ上方への変位は規制しないので、シャッターカーテンを通常に開閉する場合には何ら影響しない。
【0015】
請求項2に係る発明によれば、座板補強材を取付けたことで座板が補強され、その座板の斜め室外側上方への所定量以上の変位を強固に防止できる。

[0003]
[Patent Document 1]
JP-A-8-109780 [Patent Document 2]
JP-A-2001-73610 [0004]
[Problems to be solved by the invention]
The shutters disclosed in Patent Documents 1 and 2 can be locked from the indoor side with the shutter curtain closed, but there is a possibility that the lock may be unlocked by intentionally opening the shutter curtain using a bar.
For example, by inserting a bar between the lower frame of the shutter frame and the seat plate and forcing it, the seat plate can be easily displaced upward to unlock the lock in a short time. That is, the seat plate itself is easily displaced upward, and if the seat plate is displaced upward by a predetermined amount or more, the lock is broken and the unlocked state is obtained.
Thus, it is not preferable for crime prevention that the lock is unlocked in a short time.
In particular, in the case of a shutter mounted as a shutter on the outdoor side of a sash window, the lower frame is at a position higher than the ground, and there is a large space for squeezing the bar.
[0005]
The present invention has been made in view of the above-described problems, and its purpose is to prevent the seat plate from being easily displaced more than a predetermined amount toward the upper outside of the oblique room by forcing it using a bar. It is to provide a shutter that can be used.
[0006]
[Means for Solving the Problems]
The first invention relates to a shutter that opens and closes a shutter frame by raising and lowering a shutter curtain along the shutter frame.
The lower frame of the shutter frame is provided with a receiving member that restricts the amount of displacement of the seat plate to the upper side of the slanting room and does not regulate the straight upward displacement when the shutter curtain is closed. It is a shutter to do.
[0007]
According to a second aspect of the present invention, in the first aspect of the present invention, the seat plate reinforcing member is attached to the seat plate, and the seat plate reinforcing member and the receiving member are locked to regulate the amount of displacement of the seat plate to the upper outside of the oblique room. The shutter.
[0008]
[Operation]
According to the first invention, when the seat plate is intentionally squeezed using a bar from the outside, the amount of displacement of the seat plate that is easily displaced toward the upper oblique outer side is regulated by the receiving member. Therefore, it is possible to prevent the seat plate from being easily displaced upward by a predetermined amount by forcibly twisting the seat plate using the bar.
Therefore, it is a preferable shutter for crime prevention because it takes time for the lock to be unlocked by deliberately using a bar to displace the seat plate upward by a predetermined amount or more from outside the room.
Further, since the receiving member does not restrict the upward displacement of the seat plate, there is no influence when the shutter curtain is normally opened and closed.
[0009]
According to the second invention, the seat plate is reinforced by attaching the seat plate reinforcing member, and the displacement of the seat plate beyond the predetermined amount beyond the oblique outdoor side can be firmly prevented.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 1, a shutter frame 1, a winding / unwinding portion 2 provided on the upper portion of the shutter frame 1, and a shutter curtain 3 wound and fed by the winding / unwinding portion 2 are the basic configuration of the shutter. is there.
That is, the shutter moves up and down the shutter curtain 3 along the shutter frame 1 to open and close the shutter frame 1.
The shutter frame 1 has an upper frame 10, a lower frame 11, and left and right vertical frames 12, and the left and right vertical frames 12 include a guide portion that guides the shutter curtain 3 so as to be movable up and down, for example, guide rails 13. .
The winding and unwinding portion 2 includes a winding drum 20 and a shutter box 21 that houses the winding drum 20, and the shutter box 21 includes an upper surface plate 22, left and right side plates 23, and a front cover 24. The front cover 24 is openable and closable, and an opening 25 through which the shutter curtain 3 enters and exits is formed between the lower indoor side of the front cover 24 and the outdoor side of the upper frame 10.
The shutter curtain 3 is formed by connecting a plurality of slats 30 and attaching a seat plate 31 to the lowermost slat 30, and the uppermost slat 30 is connected to the winding drum 20.
[0011]
In the shutter described above, with the shutter curtain 3 fully closed, a bar is inserted between the seat plate 31 and the lower frame 11 from the outside, and the seat plate 31 is directed obliquely upward and outward by forcing it. Since it is easily displaced, it does not take time to displace the seat plate 31 by a predetermined amount or more to bring the lock into an unlocked state, and it can be unlocked in a short time, which is not preferable for crime prevention.
[0012]
A receiving member 40 is attached to the lower frame 11. The receiving member 40 restricts the amount of displacement of the seat plate 31 upward and obliquely outside the door when the shutter curtain 3 is closed, and does not restrict straight upward displacement. In other words, when the seat plate 31 is slightly displaced upward in the oblique outdoor side, the seat plate 31 is locked to the receiving member 40 and restricts the upward displacement. Since the receiving member 40 does not restrict the upward displacement of the seat plate 31, it does not get in the way when the shutter curtain 3 is normally opened and closed, and has no influence.
Specifically, the receiving member 40 includes an attachment piece 41 and a flange piece 42, and the attachment piece 41 is fixedly attached to the upper surface of the lower frame 11 near the outdoor side with a screw 43. A locking piece 42a is provided. Preferably, a back plate 44 is provided on the lower surface near the outdoor side of the lower frame 11, and screws 43 are screwed onto the back plate 44 and fixed thereto.
The seat plate 31 is provided with a hook-shaped piece 33 integrally on the indoor side surface 32a of the main body 32, and attached with an anti-roll-in stopper 34 on both end surfaces in the longitudinal direction, and a seat plate reinforcing member 35 is attached. For example, a seat plate reinforcing material 35 is fixed to the bowl-shaped piece 33 with screws 36.
The seat plate reinforcing member 35 is engaged with the receiving member 40.
For example, the seat plate reinforcing member 35 includes a flange 35a directed to the outdoor side, and in a normal state, the flange 35a is closer to the indoor side than the locking piece 42a of the flange 42 of the receiving member 40, and the seat plate 31 is It can move up and down and does not restrict the upward displacement of the seat plate 31 as described above.
Then, when the seat plate 31 is slightly displaced to the upper side of the oblique outdoor side as described above using the bar a as shown by the phantom line in FIG. 2, the collar piece 35a becomes the locking piece of the receiving member 40 as shown in FIG. The seat plate 31 is locked to 42a to prevent the seat plate 31 from being easily displaced upward. At this time, the lock is not damaged and remains locked.
Therefore, it is possible to regulate the amount of displacement by which the seat plate 31 can be easily displaced upward and obliquely outside by tilting using the bar, and it is difficult and time consuming to displace the seat plate 31 further upward and obliquely outside the oblique chamber. It takes.
[0013]
For this reason, the seat plate 31 is forcibly twisted using a bar, and the seat plate 31 is displaced upward until it is unlocked due to the lock being broken or the like (that is, displaced upward by a predetermined amount or more). It takes time, and is a preferable shutter for crime prevention.
[0014]
【The invention's effect】
According to the invention according to claim 1, when the seat plate is intentionally squeezed using a bar from the outside, the amount of displacement that is easily displaced toward the upper outside of the oblique exterior of the seat plate is regulated by the receiving member, Since it becomes difficult to displace beyond that, it is possible to prevent the seat plate from being easily displaced upward by a predetermined amount by forcibly twisting the seat plate using the bar.
Therefore, it is a preferable shutter for crime prevention because it takes time for the lock to be unlocked by deliberately using a bar to displace the seat plate upward by a predetermined amount or more from outside the room.
Further, since the receiving member does not restrict the upward displacement of the seat plate, there is no influence when the shutter curtain is normally opened and closed.
[0015]
According to the invention which concerns on Claim 2, a seat board is reinforced by attaching a seat board reinforcement, and the displacement more than the predetermined amount to the diagonal room outer side upper direction of the seat board can be prevented firmly.
