【発明の属する技術分野】
本発明は、戸建住宅又は集合住宅等の建物の窓等に配置し、必要に応じてこれら窓等の目隠し、遮蔽をするブラインド装置に関する。
【０００２】
【発明が解決しようとする課題】
この種のブラインド装置の一の例は、特開２００２−７０４５０号において開示したような、一対の縦枠間に配された複数のスラットと、複数のスラットの夫々の端部を支持する複数の支持アームと、複数の支持アームの両端部の夫々に回動自在に連結する互いに対向して配された第一及び第二の縦リンク列と、最上位の支持アームの略中央部に回動自在に連結しており、縦枠に設けられたスリットを規定する壁面に案内される上下移動自在な上下移動部材と、上下移動部材を上下方向に移動させる上下移動機構と、この上下移動機構による上下移動部材の上下方向の移動に起因してスラットを傾動させるチルト機構とを具備しており、チルト機構は、最上位の支持アームに一の方向の回動力を与えるように、一端で上下移動部材に連結し且つ他端で最上位の支持アームの一端に連結しているコイルばねと、このコイルばねの一の方向の回動力に抗して最上位の支持アームを逆の方向に強制的に回動させるカム機構とを具備しており、カム機構は、最上位の支持アームの一端に回転自在に設けられたカムローラと、上下移動部材が上方向に移動した際にカムローラに当接するように縦枠に設けられた当接面とを具備している。
【０００３】
ところで、上述のようなブラインド装置のチルト機構は、コイルばねの弾性力により最上位の支持アームに一の方向の回動力を与えることで、第一及び第二の縦リンク列並びに複数の支持アームを介して複数のスラットの夫々を閉鎖位置から開放位置まで傾動させるようになっており、また、上下移動機構により上下移動部材の上方向の移動に際して、カムローラを当接面に当接させて最上位の支持アームの一端における上方向の移動を抑止することによってコイルばねによる一の方向の回動力に抗して最上位の支持アームを逆の方向に強制的に回動させることで、第一及び第二の縦リンク列並びに支持アームを介して複数のスラットの夫々を開放位置から閉鎖位置まで傾動させるようになっている。
【０００４】
しかしながら、斯かるブラインド装置のチルト機構は、上下移動機構による上下移動部材の上方向の移動に際してカムローラを当接面に当接させ、この当接により最上位の支持アームの一端における上方向の移動を抑止することでコイルばねによる一の方向の回動力に抗して最上位の支持アームを逆の方向に強制的に回動させるようになっているため、最上位の支持アームを、その一端を回動軸心として回動させることとなり、斯かるチルト機構によって複数のスラットの夫々を開放位置から閉鎖位置まで、また、閉鎖位置から開放位置まで傾動させるためには、上下移動部材の上下移動量を大きくとる必要が生じる。従って、当該チルト機構では、上下移動部材を介してスラットを大きく上下移動させなければならず、而して、窓等を閉口状態にするために複数のスラットの夫々を閉鎖位置に配すると、最下位のスラットと縦枠の底壁との間で大きく開口してしまい、窓等の良好な閉口状態を得ることができない。
【０００５】
更に、斯かるブラインド装置のチルト機構は、コイルばねの弾性伸縮力によって複数のスラットの夫々の傾動状態を維持するようになっているため、風等の影響によりスラットが傾動してしまい、安定した窓等の開口及び閉口状態を得ることが困難である。
【０００６】
また、この種のブラインド装置の他の一の例は、特開２００１−１７３３４１号公報に記載のように、一対の縦枠間に配された複数のスラットと、複数のスラットの夫々の端部を支持する複数の支持アームと、複数の支持アームの両端の夫々に回動自在に連結する互いに対向して配された第一及び第二の縦リンク列と、最上位の支持アームに固定されており、縦枠に設けられた縦方向に伸びるスリットを規定する壁面に案内されて上下移動自在となっている上下移動部材と、この上下移動部材に繰り出し端が固着されているベルトを有しており、このベルトを巻き上げ又は繰り出すことで上下移動部材を上下方向に移動させる上下移動機構と、この上下移動機構による上下移動部材の上下方向の移動に起因してスラットを傾動させるチルト機構とを具備しており、チルト機構は、カムローラと、このカムローラを案内する案内面とを具備している。
【０００７】
ところで、上述のようなブラインド装置は、上下移動機構によるベルトの巻き上げによって上下移動部材に上方向の移動力を与えて上下移動部材をスリットに沿って上方向に移動させ、当該上下移動部材の上方向の移動に際し、カムローラを案内面に案内させてチルトアームの上方向の移動を抑止することによって、当該チルトアームを、カムローラを中心として回動させると共にチルトアームに固定された最上位の支持アーム等を介して複数のスラットの夫々を傾動させるようになっている。
【０００８】
しかしながら、斯かるブラインド装置は、カムローラを中心とするチルトアームの回動と一対一に対応して支持アームが回動されるようになっているため、閉口状態にするためには上下移動部材の上方向の移動量を大きくとる必要が生じる。従って、当該ブラインド装置では、上下移動部材を介してスラットを大きく上下移動させなければならず、而して、窓等を閉口状態にするために複数のスラットの夫々を閉鎖位置に配すると、最下位のスラットと縦枠の底壁との間で大きく開口してしまい、窓等の良好な閉口状態を得ることができない。
【０００９】
更に、斯かるブラインド装置は、開口状態への移行において、チルト部材を支持アームの中心で回動させることから、案内面によって規定される溝部を上枠外装内に収納等をすることが困難である。
【００１０】
本発明は、前記諸点に鑑みてなされたものであって、その目的とするところは、複数のスラットの夫々を傾動させる為に必要な複数のスラットの夫々の上下移動量を減らして窓等の良好な閉口状態を得ることができ、複数のスラットの夫々の傾動状態を強固に支持してこれらの開放、閉口状態を安定させることができ、更に、チルト機構のカムを案内する案内面によって規定される溝部等を上枠外装内等に納めることが容易に行えるブラインド装置を提供することにある。
【００１１】

BACKGROUND OF THE INVENTION
The present invention relates to a blind device that is arranged on a window or the like of a building such as a detached house or an apartment house, and that blinds and shields these windows as necessary.
[0002]
[Problems to be solved by the invention]
One example of this type of blind device is a plurality of slats disposed between a pair of vertical frames as disclosed in Japanese Patent Laid-Open No. 2002-70450, and a plurality of slats that support respective end portions. A support arm, first and second vertical link rows arranged opposite to each other and rotatably connected to both end portions of a plurality of support arms, and a substantially central portion of the uppermost support arm. A vertically movable member that is freely connected and is guided by a wall surface defining a slit provided in a vertical frame, a vertically movable member that moves the vertically movable member in a vertical direction, and a vertical movement mechanism And a tilt mechanism that tilts the slat due to the vertical movement of the vertical movement member, and the tilt mechanism moves up and down at one end so as to provide a rotational force in one direction to the uppermost support arm. Connected to the member A coil spring connected to one end of the uppermost support arm at the other end, and a cam for forcibly rotating the uppermost support arm in the opposite direction against the rotational force in one direction of the coil spring The cam mechanism is provided on the vertical frame so as to come into contact with the cam roller when the vertically moving member moves upward, and a cam roller rotatably provided at one end of the uppermost support arm. A contact surface.
[0003]
By the way, the tilt mechanism of the blind device as described above provides the first and second vertical link rows and the plurality of support arms by applying a turning force in one direction to the uppermost support arm by the elastic force of the coil spring. Each of the plurality of slats is tilted from the closed position to the open position via the cam, and the cam roller is brought into contact with the contact surface when the vertical movement member is moved upward by the vertical movement mechanism. By restraining the upward movement at one end of the upper support arm, the uppermost support arm is forcibly rotated in the opposite direction against the rotational force in one direction by the coil spring. And each of the plurality of slats is tilted from the open position to the closed position via the second vertical link row and the support arm.
[0004]
However, the tilt mechanism of such a blind device causes the cam roller to come into contact with the contact surface during the upward movement of the vertical movement member by the vertical movement mechanism, and the upward movement at one end of the uppermost support arm by this contact. Since the uppermost support arm is forcibly rotated in the opposite direction against the rotational force in one direction by the coil spring, the uppermost support arm has its one end The vertical movement member is moved up and down in order to tilt each of the plurality of slats from the open position to the closed position and from the closed position to the open position by such a tilt mechanism. A large amount needs to be taken. Therefore, in the tilt mechanism, the slats must be greatly moved up and down via the up-and-down moving member. A large opening is formed between the lower slat and the bottom wall of the vertical frame, and a favorable closed state such as a window cannot be obtained.
[0005]
Furthermore, since the tilt mechanism of such a blind device maintains the tilted state of each of the plurality of slats by the elastic expansion and contraction force of the coil spring, the slats are tilted by the influence of the wind and the like, and are stable. It is difficult to obtain an opening and a closed state such as a window.
[0006]
Another example of this type of blind device is a plurality of slats arranged between a pair of vertical frames and respective end portions of the plurality of slats as described in JP-A-2001-173341. Fixed to the uppermost support arm, a plurality of support arms for supporting the first support arm, first and second vertical link rows arranged opposite to each other and rotatably connected to both ends of the plurality of support arms. A vertically moving member guided by a wall surface defining a longitudinally extending slit provided in the vertical frame and freely movable up and down, and a belt having a feeding end fixed to the vertically moving member. A vertical movement mechanism for moving the vertical movement member in the vertical direction by winding or unwinding the belt, and a tilt machine for tilting the slats due to the vertical movement of the vertical movement member by the vertical movement mechanism And comprising bets, tilt mechanism is equipped with cam roller, and a guide surface for guiding the cam roller.
[0007]
By the way, the blind device as described above applies an upward movement force to the vertical movement member by winding the belt by the vertical movement mechanism to move the vertical movement member upward along the slit, When moving in the direction, the cam roller is guided to the guide surface to prevent the upward movement of the tilt arm, thereby rotating the tilt arm about the cam roller and fixing the uppermost support arm to the tilt arm. Each of the plurality of slats is tilted through the like.
[0008]
However, in such a blind device, the support arm is rotated in one-to-one correspondence with the rotation of the tilt arm around the cam roller. It is necessary to increase the amount of movement in the upward direction. Therefore, in the blind device, the slats must be greatly moved up and down via the up-and-down moving member. Therefore, if each of the plurality of slats is placed at the closed position in order to close the windows, etc. A large opening is formed between the lower slat and the bottom wall of the vertical frame, and a favorable closed state such as a window cannot be obtained.
[0009]
Furthermore, since such a blind device rotates the tilt member around the center of the support arm in the transition to the open state, it is difficult to store the groove defined by the guide surface in the upper frame exterior. is there.
[0010]
The present invention has been made in view of the above-mentioned points, and the object of the present invention is to reduce the amount of vertical movement of each of the plurality of slats necessary for tilting each of the plurality of slats to reduce the window and the like. A good closing state can be obtained, the tilting state of each of the plurality of slats can be firmly supported, and the opening and closing states can be stabilized. Further, the guide surface for guiding the cam of the tilt mechanism is specified. It is an object of the present invention to provide a blind device that can easily store a groove portion or the like in an upper frame exterior or the like.
