Description

本発明は、シャッタ扉を開閉する際の衝撃を緩和する機構を備えたシャッタに関する。   The present invention relates to a shutter having a mechanism for reducing an impact when opening and closing a shutter door.

従来、シャッタ扉を閉めるときの衝撃を緩和するシャッタとして、特許文献１に開示のものがある。図９に示すように、このシャッタ１００は、シャッタ扉１０２を閉めるときにシャッタ扉１０２の重量を受け留める制動機構部１０６を設ける。この制動機構部１０６は、逆Ｕ字状に形成する一対のガイドレール１０３の前部のそれぞれにスライド自在に外嵌されてシャッタ扉１０２の閉移動途中からシャッタ扉１０２と当接する当り受部材１６２と、一端をガイドレール１０３に設けた凹溝内に固定させ他端を当り受部材１６２と接続させた伸縮自在の弾性部材１６１とを有する。これによると、シャッタ扉１０２を閉じるとき、シャッタ扉１０２の前端部が当り受部材１６２と当接すると弾性部材１６１が引っ張られ、この弾性部材１６１の引っ張り弾性力によってシャッタ扉１０２の重量が受け留められてシャッタ扉１０２の閉動作速度が十分に減速されるので、大きな衝撃を与えることなくシャッタ扉１０２を静かに閉めることができるとする。   Conventionally, there is a shutter disclosed in Patent Document 1 as a shutter for reducing the impact when closing the shutter door. As shown in FIG. 9, the shutter 100 is provided with a braking mechanism 106 that receives the weight of the shutter door 102 when the shutter door 102 is closed. The braking mechanism portion 106 is slidably fitted on each of the front portions of the pair of guide rails 103 formed in an inverted U shape so that the contact receiving member 162 abuts against the shutter door 102 while the shutter door 102 is being moved. And a telescopic elastic member 161 having one end fixed in a groove provided in the guide rail 103 and the other end connected to the receiving member 162. According to this, when the shutter door 102 is closed, the elastic member 161 is pulled when the front end portion of the shutter door 102 comes into contact with the receiving member 162, and the weight of the shutter door 102 is received by the tensile elastic force of the elastic member 161. Since the closing operation speed of the shutter door 102 is sufficiently reduced, the shutter door 102 can be quietly closed without giving a large impact.

特開２００３−３７６９号公報JP 2003-3769 A

しかしながら、従来のシャッタ１００では、シャッタ扉１０２を閉めるときのみならず、シャッタ扉１０２を開けるときにも衝撃緩和させるには、ガイドレール１０３の前部側の弾性部材１６１とは別に、ガイドレール１０３の後部にも同様の弾性部材１６１を設ける必要がある。そうすると、シャッタ扉１０２を閉めるときと開けるときのそれぞれに対応してガイドレール１０３の前部と後部のそれぞれに弾性部材１６１や当り受部材１６２を設けることとなり、部品点数が多くなってシャッタ１００の構成が複雑になり、また、コストも高くなってしまう。また、前面側に当り受け部材１６２等が配置されると美観が良くなく家具などへの採用が難しかった。   However, in the conventional shutter 100, in order to reduce the impact not only when the shutter door 102 is closed but also when the shutter door 102 is opened, the guide rail 103 is separated from the elastic member 161 on the front side of the guide rail 103. It is necessary to provide a similar elastic member 161 at the rear part. Then, the elastic member 161 and the contact receiving member 162 are provided at the front and rear portions of the guide rail 103 corresponding to the time when the shutter door 102 is closed and the time when the shutter door 102 is opened. The configuration becomes complicated and the cost increases. Further, when the contact receiving member 162 or the like is arranged on the front side, the appearance is not good and it is difficult to adopt it for furniture.

そこで、同じ弾性部材１６１によりシャッタ扉１０２を閉じるときも開くときもシャッタ扉１０２の移動を制動させるように、例えば、弾性部材１６１の一端をシャッタ扉１０２に固定し、他端をシャッタ扉１０２を取り付けた筐体に固定させることが考えられる（図１０（ａ）（ｂ）参照）。しかしながら、弾性部材１６１の取り付け位置によって、シャッタ扉１０２を閉じるに従って弾性部材１６１がこのシャッタ１００の内部空間１０７に深く入り込んで内部の配置物を引っ掛ける等の不具合を生じさせたり（図１０（ａ）参照）、弾性部材１６１の弾性力が強く効きすぎてシャッタ扉１０２の開放時にシャッタ扉１０２が閉まる側に移動して完全に開放保持できない等の不具合を生じさせる（図１０（ｂ）参照）。   Therefore, for example, one end of the elastic member 161 is fixed to the shutter door 102 and the other end of the shutter door 102 is fixed so that the movement of the shutter door 102 is braked when the shutter door 102 is closed and opened by the same elastic member 161. It is conceivable to fix it to the attached housing (see FIGS. 10A and 10B). However, depending on the mounting position of the elastic member 161, there is a problem that the elastic member 161 deeply enters the internal space 107 of the shutter 100 as the shutter door 102 is closed, and the internal arrangement is caught (FIG. 10A). The elastic force of the elastic member 161 is so strong that when the shutter door 102 is opened, the shutter door 102 moves to the closing side and cannot be completely held open (see FIG. 10B).

本発明は、上記事情に鑑みてなされたものであり、同じ弾性部材によりシャッタ扉の開閉時の衝撃を緩和する機構を設けるにあたり、弾性部材が内部空間に入ることを抑制すると共にシャッタ扉の開閉保持を確実に行えるシャッタを提供することを課題とする。   The present invention has been made in view of the above circumstances, and in providing a mechanism for mitigating the impact when the shutter door is opened and closed by the same elastic member, the elastic member is prevented from entering the internal space and the shutter door is opened and closed. It is an object to provide a shutter that can be reliably held.

本発明に係るシャッタは、
折れ曲げ可能なシャッタ扉を一対のガイドレール間に走行自在に取り付け、上記シャッタ扉を閉じたときには該シャッタ扉の前部が下方に垂下されると共に、上記シャッタ扉を開いたときには該シャッタ扉の後部が下方に垂下されるように構成されたシャッタであって、
上記シャッタ扉を開閉する際に該シャッタ扉の重量を受け留める制動機構部を設け、
上記制動機構部は、伸縮自在の弾性部材を備え、
上記弾性部材は、一端を上記シャッタ扉に取り付けると共に他端を移動可能にレールに取り付け、上記シャッタ扉を閉じるときにはシャッタ扉の閉移動の途中に上記弾性部材の他端が該弾性部材の引っ張り弾性力により上記レールの一方移動限まで移動した閉動作制動姿勢となり、上記シャッタ扉を開くときもシャッタ扉の開移動の途中に上記弾性部材の他端が該弾性部材の引っ張り弾性力により上記レールの他方移動限まで移動した開動作制動姿勢となるように移動可能に構成されている。 The shutter according to the present invention is:
A foldable shutter door is movably mounted between a pair of guide rails. When the shutter door is closed, the front portion of the shutter door is suspended downward, and when the shutter door is opened, the shutter door A shutter configured to hang downward at the rear,
A braking mechanism for receiving the weight of the shutter door when opening and closing the shutter door;
The braking mechanism includes an elastic member that can be expanded and contracted,
The elastic member has one end attached to the shutter door and the other end movably attached to the rail. When the shutter door is closed, the other end of the elastic member is pulled elastically during the closing movement of the shutter door. When the shutter door is opened, the other end of the elastic member is moved by the tensile elastic force of the elastic member during the opening movement of the shutter door even when the shutter door is opened. On the other hand, it is configured to be movable so as to be in the open operation braking posture moved to the movement limit.

上記構成によれば、シャッタ扉を閉めて行くと、弾性部材が上記閉動作制動姿勢となり、該弾性部材の引っ張り弾性力によってシャッタ扉の閉動作速度が十分に減速され、大きな衝撃を与えることなくシャッタ扉を静かに閉めることができる。一方、シャッタ扉を開けて行くと、上記弾性部材が上記開動作制動姿勢となり、該弾性部材の引っ張り弾性力によってシャッタ扉の開動作速度が十分に減速され、シャッタ扉を開けるときも大きな衝撃を与えることなくシャッタ扉を静かに開けることができる。   According to the above configuration, when the shutter door is closed, the elastic member becomes the closing operation braking posture, and the closing operation speed of the shutter door is sufficiently reduced by the tensile elastic force of the elastic member without giving a large impact. The shutter door can be closed gently. On the other hand, when the shutter door is opened, the elastic member is in the opening motion braking posture, and the opening operation speed of the shutter door is sufficiently decelerated by the tensile elastic force of the elastic member, and a large impact is applied even when the shutter door is opened. The shutter door can be opened gently without giving.

そして、上記弾性部材は、シャッタ扉を閉じるときの閉動作制動姿勢と開くときの開動作制動姿勢の各姿勢に変更するときにはシャッタに囲われた内部空間に深く入らないように弾性部材の他端が移動可能となっている。従って、シャッタ扉を開閉する際に弾性部材が上記各姿勢に変更するときに弾性部材がシャッタに囲われた内部空間に深く入ることがない。よって、シャッタ扉を開閉する際にシャッタに囲われた内部空間の配置物に弾性部材が引っ掛かることがなく上記内部空間を広く確保することができる。   The elastic member is connected to the other end of the elastic member so as not to enter deeply into the internal space surrounded by the shutter when changing to the closing operation braking posture when closing the shutter door and the opening operation braking posture when opening the shutter door. Is movable. Therefore, when the elastic member changes to each of the above postures when opening and closing the shutter door, the elastic member does not enter deeply into the internal space surrounded by the shutter. Therefore, when the shutter door is opened and closed, the elastic member is not caught by the arrangement of the internal space surrounded by the shutter, and the internal space can be secured widely.

また、弾性部材は、他端が移動してシャッタ扉を閉じるときの閉動作制動姿勢と開くときの開動作制動姿勢となることにより、シャッタ扉の開閉時に弾性部材の引っ張り弾性力が強く効きすぎることもなくシャッタ扉の開閉保持を確実に行える。   In addition, the elastic member has a closing operation braking posture when the other end moves to close the shutter door and an opening operation braking posture when the shutter door is opened, so that the tensile elastic force of the elastic member is too strong when the shutter door is opened and closed. Without any problem, the shutter door can be reliably opened and closed.

上記一対のガイドレールが逆Ｕ字状に形成されて、該ガイドレールを走行するシャッタ扉は、閉移動の途中から閉鎖位置までシャッタ扉後端部が横移動し、開移動の途中から開放位置までシャッタ扉後端部が縦移動するように構成され、
上記レールは、上記一対のガイドレールの後部の外周位置近傍にそれぞれ上下方向に延設されて一対設けられており、
上記弾性部材は、２個有し、
各弾性部材は、一端がシャッタ扉後端部の外側面に取り付けられ、他端が上記各レールのそれぞれに取り付けられて、上記閉動作制動姿勢として横向き姿勢となり、上記開動作制動姿勢として縦向き姿勢となるように移動可能に構成されているのが望ましい。 The pair of guide rails are formed in an inverted U-shape, and the shutter door that travels on the guide rail has its rear end moved laterally from the middle of the closing movement to the closing position, and the opening position from the middle of the opening movement. The rear end of the shutter door is configured to move vertically until
The rails are provided in a pair extending in the vertical direction in the vicinity of the outer peripheral position of the rear part of the pair of guide rails,
The elastic member has two pieces,
Each elastic member has one end attached to the outer surface of the rear end of the shutter door, and the other end attached to each of the rails, and has a lateral posture as the closing operation braking posture and a vertical orientation as the opening operation braking posture. It is desirable to be configured to be movable so as to be in a posture.

これによれば、シャッタ扉を閉じて行くとき、シャッタ扉後端部の上方移動に伴ってレールの下方限（他方移動限）に位置していた弾性部材の他端が上方へ引っ張られてレールの上方へ移動する。続いて、シャッタ扉後端部の横移動に伴って弾性部材の他端がさらに上方へ引っ張られてレールの上方限（一方移動限）まで移動する。そして、シャッタ扉が閉鎖位置に達するまでシャッタ扉後端部が横移動する間は、弾性部材が横向き姿勢となって引っ張られる。従って、シャッタ扉を閉じる間に弾性部材がシャッタに囲われた内部空間に深く入り込むことが防止される。   According to this, when the shutter door is closed, the other end of the elastic member located at the lower limit (the other movement limit) of the rail is pulled upward along with the upward movement of the rear end of the shutter door. Move up. Subsequently, the other end of the elastic member is further pulled upward along with the lateral movement of the rear end of the shutter door, and moves to the upper limit (one movement limit) of the rail. Then, while the rear end of the shutter door moves laterally until the shutter door reaches the closed position, the elastic member is pulled in a horizontal posture. Therefore, the elastic member is prevented from entering deeply into the internal space surrounded by the shutter while the shutter door is closed.

一方、シャッタ扉を開いて行くとき、シャッタ扉後端部が横移動から下方移動（縦移動）となり、この下方移動に伴ってレールの上方限に位置していた弾性部材の他端が下方へ引っ張られてレールの下方へ移動する。続いて、シャッタ扉後端部の下方移動に伴って弾性部材の他端がさらに下方へ引っ張られてレールの下方限まで移動する。そして、シャッタ扉が開放位置に達するまでシャッタ扉後端部が下方移動する間は、弾性部材が縦向き姿勢となって引っ張られる。従って、シャッタ扉を開く間も弾性部材がシャッタに囲われた内部空間に深く入り込むことが防止される。   On the other hand, when the shutter door is opened, the rear end of the shutter door is moved downward from the lateral movement (vertical movement), and the other end of the elastic member located at the upper limit of the rail is moved downward along with the downward movement. Pulled to move down the rail. Subsequently, as the rear end of the shutter door moves downward, the other end of the elastic member is further pulled downward to move to the lower limit of the rail. The elastic member is pulled in a vertical orientation while the rear end of the shutter door moves downward until the shutter door reaches the open position. Therefore, the elastic member is prevented from entering deeply into the internal space surrounded by the shutter while the shutter door is opened.

このように、シャッタ扉を開閉する際に弾性部材が上記各姿勢に変更するときに弾性部材の他端が移動することにより、弾性部材がシャッタに囲われた内部空間に深く入ることがない。よって、シャッタ扉を開閉する際にシャッタに囲われた内部空間の配置物に弾性部材が引っ掛かることがなく上記内部空間を広く確保することができる。   As described above, when the elastic member changes to each of the above postures when opening and closing the shutter door, the other end of the elastic member moves, so that the elastic member does not enter deeply into the internal space surrounded by the shutter. Therefore, when the shutter door is opened and closed, the elastic member is not caught by the arrangement of the internal space surrounded by the shutter, and the internal space can be secured widely.

また、弾性部材は、他端が移動してシャッタ扉を閉じるときの横向き姿勢と開くときの縦向き姿勢となることにより、シャッタ扉の開閉時に弾性部材の引っ張り弾性力が強く効きすぎることもなくシャッタ扉の開閉保持を確実に行える。   In addition, the elastic member has a horizontal posture when the other end moves to close the shutter door and a vertical posture when the shutter door is opened, so that the tensile elastic force of the elastic member does not become too strong when the shutter door is opened and closed. The shutter door can be reliably opened and closed.

上記弾性部材の他端が、移動限を設定可能なストッパを有した上記レールに対して低摩擦で移動可能に設けたスライド部材に取り付けられている場合は、シャッタ扉を開閉するときに弾性部材の他端が円滑に移動して円滑に上記各姿勢となる。   When the other end of the elastic member is attached to a slide member that is movable with low friction with respect to the rail having a stopper capable of setting a movement limit, the elastic member is used when the shutter door is opened and closed. The other end of the lens moves smoothly and assumes the above postures smoothly.

上記弾性部材の一端が、上記シャッタ扉に対して揺動可能となるようにヒンジ部材を介して取り付けられている場合は、シャッタ扉を開閉するときに弾性部材の一端が円滑に揺動して円滑に上記各姿勢となる。   When one end of the elastic member is attached via a hinge member so as to be swingable with respect to the shutter door, one end of the elastic member swings smoothly when the shutter door is opened and closed. The above postures are smoothly achieved.

以上のように、本発明に係るシャッタによれば、同じ弾性部材によってシャッタ扉を閉めるときも開けるときもシャッタ扉の移動速度を減速させて開閉時の衝撃を緩和できる。従って、シャッタ扉を静かに開閉することができ、大きな衝撃音を発生させることもなく、且つ各部に大きな衝撃を与えることがないためシャッタの耐久性を向上できる。   As described above, according to the shutter of the present invention, it is possible to reduce the impact at the time of opening and closing by reducing the moving speed of the shutter door when the shutter door is closed and opened by the same elastic member. Therefore, the shutter door can be opened and closed quietly, no large impact sound is generated, and no great impact is applied to each part, so that the durability of the shutter can be improved.

加えて、シャッタ扉を開閉する際に弾性部材がシャッタに囲われた内部空間に深く入ることがないので、内部空間の配置物に弾性部材が引っ掛かることがなく上記内部空間を広く確保することができる。さらに、弾性部材は、他端が移動してシャッタ扉を閉じるときの閉動作制動姿勢と開くときの開動作制動姿勢となることにより、シャッタ扉の開閉時に弾性部材の引っ張り弾性力が強く効きすぎることもなくシャッタ扉の開閉保持を確実に行える。   In addition, since the elastic member does not enter deeply into the internal space surrounded by the shutter when opening and closing the shutter door, the internal space can be secured widely without the elastic member being caught by the arrangement in the internal space. it can. Furthermore, the elastic member has a closing operation braking posture when the other end moves to close the shutter door and an opening operation braking posture when the shutter door is opened, so that the tensile elastic force of the elastic member is too strong when the shutter door is opened and closed. Without any problem, the shutter door can be reliably opened and closed.

図１〜図３に示すように、実施の形態によるシャッタ１は、前面が開口する筐体１０に一対のガイドレール３を設け、この一対のガイドレール３間に折曲可能なシャッタ扉２を走行自在に取り付け、このシャッタ扉２により筐体１０の前面開口部が開閉されるようにしたものである。図４を参照して、一対のガイドレール３は、筐体１０の左右の側壁１１の内側面において対向位置にそれぞれ形成された断面コ字状の凹溝により構成される。各ガイドレール３は、逆Ｕ字状に形成されており、シャッタ扉２は、閉移動の途中から閉鎖位置までシャッタ扉後端部２０が横移動し（図２（ａ）参照）、開移動の途中から開放位置までシャッタ扉後端部２０が縦移動するように構成される（図３（ａ）参照）。   As shown in FIGS. 1 to 3, the shutter 1 according to the embodiment is provided with a pair of guide rails 3 in a housing 10 whose front surface is open, and a shutter door 2 that can be bent between the pair of guide rails 3. It is attached so that it can run freely, and the front opening of the housing 10 is opened and closed by the shutter door 2.

ところで、このシャッタ１には、シャッタ扉２を開閉する際にシャッタ扉２の重量を受け留める制動機構部６が設けられている（図２、図３を参照。）。制動機構部６は、一端をシャッタ扉２に取り付けると共に、他端を移動可能にレール６２に取り付けた伸縮自在の弾性部材（引っ張りバネ）６１を備える。レール６２は、一対のガイドレール３の後部の外周位置近傍にそれぞれ上下方向に延設されて一対設けられている。この一対のレール６２は、筐体１０の左右の側壁１１に取り付けられている。なお、レール６２は、後述のスライド部材６３が走行自在に取り付けられる凹溝を有している。弾性部材６１は、２個有し、各弾性部材６１は、一端が両方ともシャッタ扉後端部２０の外側面の略中央に取り付けられ、他端がそれぞれ各レール６２に取り付けられている。具体的には、各弾性部材６１の一端は、シャッタ扉２に設けたヒンジ部材６５に取り付けられて揺動可能となっており（図８参照）、また、各弾性部材６１の他端は、各レール６２に沿って上下移動するようにレール６２に設けたスライド部材６３に取り付けられている（図７参照）。スライド部材６３にはレール６２に低摩擦で移動するように転動体６４が取り付けられており、例えば、静摩擦係数を０．０５以下とし、望ましくは０．０１以下とする。
なお、図７を参照して、レール６２の下側にはスライド部材６３の移動限を設定するストッパ６６が設けられており、これにより各弾性部材６１の弾性力の効き、移動姿勢などを適宜に調整することができる。このストッパ６６は、レール６２の下側にだけ設けるが上側にも設けるようにしてもよい。 By the way, the shutter 1 is provided with a brake mechanism 6 for receiving the weight of the shutter door 2 when the shutter door 2 is opened and closed (see FIGS. 2 and 3). The braking mechanism unit 6 includes an elastic member 61 (extension spring) 61 having one end attached to the shutter door 2 and the other end movably attached to the rail 62. A pair of rails 62 are provided extending in the vertical direction in the vicinity of the outer peripheral position of the rear part of the pair of guide rails 3. The pair of rails 62 are attached to the left and right side walls 11 of the housing 10.

Referring to FIG. 7, a stopper 66 for setting the movement limit of the slide member 63 is provided on the lower side of the rail 62, whereby the effect of the elastic force of each elastic member 61, the movement posture, etc. are appropriately set. Can be adjusted. The stopper 66 is provided only on the lower side of the rail 62, but may be provided on the upper side.

以上の構成より、このシャッタ１は、シャッタ扉２を閉じて行くとき、図２を参照して、シャッタ扉後端部２０の上方移動に伴ってレール６２の下方限位置に配置されていた弾性部材６１の他端が上方へ引っ張られてレール６２の上方へ移動する。続いて、シャッタ扉後端部２０の横移動に伴って弾性部材６１の他端がさらに上方へ引っ張られてレール６２の上方限まで移動する。そして、シャッタ扉２が閉鎖位置に達するまでシャッタ扉後端部２０が横移動する間は、弾性部材６１が横向き姿勢（閉動作制動姿勢）となって引っ張られる。従って、シャッタ扉２を閉じる間に弾性部材６１がシャッタ１で囲われた内部空間７に深く入り込むことが防止される。そして、この弾性部材６１の引っ張り弾性力によってシャッタ扉２を閉じるときにシャッタ扉２の重量が受け留められる。   With the above configuration, when the shutter 1 is closed, the shutter 1 is elastically disposed at the lower limit position of the rail 62 with the upward movement of the rear end portion 20 of the shutter door with reference to FIG. The other end of the member 61 is pulled upward and moves upward of the rail 62. Subsequently, the other end of the elastic member 61 is further pulled upward with the lateral movement of the rear end portion 20 of the shutter door, and moves to the upper limit of the rail 62. Then, while the shutter door rear end 20 moves laterally until the shutter door 2 reaches the closed position, the elastic member 61 is pulled in a lateral posture (closed operation braking posture). Therefore, the elastic member 61 is prevented from entering deeply into the internal space 7 surrounded by the shutter 1 while the shutter door 2 is closed. The weight of the shutter door 2 is received when the shutter door 2 is closed by the tensile elastic force of the elastic member 61.

一方、シャッタ扉２を開いて行くとき、図３を参照して、シャッタ扉後端部２０が横移動から縦移動に移って下方移動するに伴ってレール６２の上方限位置に配置されていた弾性部材６１の他端が下方へ引っ張られてレール６２の下方へ移動する。続いて、シャッタ扉後端部２０の下方移動に伴って弾性部材６１の他端がさらに下方へ引っ張られてレール６２の下方限まで移動する。そして、シャッタ扉２が開放位置に達するまでシャッタ扉後端部２０が下方移動する間は、弾性部材６１が縦向き姿勢（開動作制動姿勢）となって引っ張られる。従って、シャッタ扉２を開く間も弾性部材６１がシャッタ１で囲われた内部空間７に深く入り込むことが防止される。そして、この弾性部材６１の引っ張り弾性力によってシャッタ扉２を開くときにシャッタ扉２の重量が受け留められる。   On the other hand, when the shutter door 2 is opened, referring to FIG. 3, the rear end portion 20 of the shutter door is arranged at the upper limit position of the rail 62 as it moves downward from the horizontal movement to the vertical movement. The other end of the elastic member 61 is pulled downward and moves downward of the rail 62. Subsequently, as the shutter door rear end 20 moves downward, the other end of the elastic member 61 is further pulled downward to move to the lower limit of the rail 62. Then, while the shutter door rear end 20 moves downward until the shutter door 2 reaches the open position, the elastic member 61 is pulled in a vertical posture (open operation braking posture). Accordingly, the elastic member 61 is prevented from entering the internal space 7 surrounded by the shutter 1 while the shutter door 2 is opened. The weight of the shutter door 2 is received when the shutter door 2 is opened by the tensile elastic force of the elastic member 61.

また、各弾性部材６１の他端が各レール６２に対して低摩擦で移動可能に設けたスライド部材６３に取り付けられているので、シャッタ扉２を開閉するときに各弾性部材６１の他端が円滑に移動して円滑に上記各姿勢となる。また、各弾性部材６１の一端がシャッタ扉２に対して揺動可能となるようにヒンジ部材６５を介して取り付けられているので、シャッタ扉２を開閉するときに各弾性部材６１の一端が円滑に揺動して円滑に上記各姿勢となる。   Further, since the other end of each elastic member 61 is attached to a slide member 63 provided so as to be movable with low friction with respect to each rail 62, the other end of each elastic member 61 is not opened when the shutter door 2 is opened and closed. It moves smoothly and takes the above postures smoothly. In addition, since one end of each elastic member 61 is attached via a hinge member 65 so as to be swingable with respect to the shutter door 2, one end of each elastic member 61 is smooth when the shutter door 2 is opened and closed. Oscillates smoothly to the above postures.

このように、シャッタ扉２を開閉する際にシャッタ扉２の開閉に応じて各弾性部材６１が上記各姿勢に変更するときに各弾性部材６１の他端が上下移動することにより、各弾性部材６１がシャッタ１で囲われた内部空間７に深く入ることがない。よって、シャッタ扉２を開閉する際に内部空間７の配置物に弾性部材６１が引っ掛かることがなく上記内部空間７を広く確保することができる。また、各弾性部材６１は、他端が移動してシャッタ扉２を閉じるときの横向き姿勢（閉動作制動姿勢）と開くときの縦向き姿勢（開動作制動姿勢）となることにより、シャッタ扉２の開閉時に各弾性部材６１の引っ張り弾性力が強く効きすぎることもなくシャッタ扉２の開閉保持を確実に行える。   Thus, when each elastic member 61 changes to each said attitude | position according to opening / closing of the shutter door 2 when opening / closing the shutter door 2, when the other end of each elastic member 61 moves up and down, each elastic member 61 does not enter deeply into the internal space 7 surrounded by the shutter 1. Therefore, when the shutter door 2 is opened and closed, the elastic member 61 is not caught on the arrangement of the internal space 7 and the internal space 7 can be secured widely. Further, each elastic member 61 moves in the horizontal direction (closed operation braking posture) when the other end moves to close the shutter door 2 and in the vertical posture (open operation braking posture) when opened, so that the shutter door 2 is opened. The opening and closing of the shutter door 2 can be reliably performed without the tension elastic force of each elastic member 61 being too strong when opening and closing.

また、本実施形態に係るシャッタ１によれば、共通の弾性部材６１によってシャッタ扉２の開閉時におけるシャッタ扉２の重量が受け留められるので、部品点数を増やさずにシャッタ扉２を閉めるときも開けるときもシャッタ扉２の移動速度を減速させて開閉時の衝撃を緩和できる。従って、シャッタ扉２を静かに開閉することができ、大きな衝撃音を発生させることもなく、且つ各部に大きな衝撃を与えることがないためシャッタ１の耐久性を向上できる。また、共通の弾性部材６１によってシャッタ扉２の開閉時の衝撃を緩和できるので、シャッタ１の構造が複雑になることもなく、また、コストを低く抑えることができる。さらに、制動機構部６は、後部側に配置することで筐体１０の外観から見えないので美観が良く、よってこのシャッタ１を家具などにも適用し易い。   Further, according to the shutter 1 according to the present embodiment, the weight of the shutter door 2 when the shutter door 2 is opened and closed is received by the common elastic member 61, so that the shutter door 2 can be closed without increasing the number of parts. Even when the shutter door is opened, the moving speed of the shutter door 2 can be reduced to reduce the impact at the time of opening and closing. Accordingly, the shutter door 2 can be opened and closed quietly, no large impact sound is generated, and no great impact is applied to each part, so that the durability of the shutter 1 can be improved. Further, since the impact at the time of opening and closing the shutter door 2 can be mitigated by the common elastic member 61, the structure of the shutter 1 is not complicated, and the cost can be kept low. Further, the braking mechanism 6 is arranged on the rear side so that it cannot be seen from the appearance of the housing 10, so that the aesthetic appearance is good. Therefore, the shutter 1 can be easily applied to furniture and the like.

なお、上記実施形態では、各弾性部材６１の一端をともにシャッタ扉後端部２０の略中央位置に取り付けるが、それぞれの配置側寄りに取り付けるようにしてもよい。この場合、各弾性部材６１を短く構成することができる。
また、上記実施形態では、弾性部材６１を２個設けたが、１個であってもよい。
また、上記実施形態では、図示した弾性部材６１は引っ張りバネであるが、これに限らず、ゴム紐、シリンダー機構等の各種の弾性部材が適用可能である。
さらに、本発明に係るシャッタは、上記実施形態で図示したものに限らず、適宜に変更することができる。 In the above-described embodiment, one end of each elastic member 61 is attached to the approximate center position of the shutter door rear end 20, but may be attached closer to each arrangement side. In this case, each elastic member 61 can be configured to be short.
Moreover, in the said embodiment, although the two elastic members 61 were provided, one piece may be sufficient.
Moreover, in the said embodiment, although the illustrated elastic member 61 is a tension spring, it is not restricted to this, Various elastic members, such as a rubber string and a cylinder mechanism, are applicable.
