    • La boîte à ressort (1) de dispositif antichute de rideau roulant à déplacement vertical comporte une bobine formée de deux flasques (3), sur laquelle est enroulé le rideau, tournant autour d'un arbre fixe (2), et un ressort de compensation (4) dont l'extrémité intérieure (5) est fixé sur cet arbre (2) et dont l'extrémité extérieure (6) est fixée sur une barrette (16) mobile en translation dans des boutonnières (17) agencées à la périphérie des flasques (3). L'extrémité de la barrette (16) joue le rôle de gâchette libérant le doigt (10) d'un verrou (8), solidaire des flasques (3), en direction d'une roue crantée (7) solidaire de l'arbre fixe (2), en cas de rupture du ressort (4). Le verrou (8), dont le doigt (10) possède un degré de liberté permettant la descente du rideau pas à pas après blocage, est un ensemble mécanique pré-assemblé en atelier.
      Application aux rideaux roulants motorisés ou mus à la main.
    • 该箱体具有补偿螺旋弹簧(4),其外端通过夹子与杆(16)成一体。 杆以平行方式更靠近凸缘的周边以两个键孔(17)可移动地平移地安装。 杆具有与手指(10)的端部配合的端部,以在弹簧的正常状态下将手指保持在与凹口(9)一定距离处。 在弹簧破裂之后,杆的端部与手指的末端分离,以将由复位弹簧(18)驱动的手指的端部沿着径向向着凹口释放。

    • The present invention provides an opening/closing device that is provided with a structure for obstructing contact by a braking engagement section or a locking engagement section to an object or the like, and so it is possible to prevent the perimeter of a guide rail from becoming thicker by means of the structure. In the opening/closing device, a braking engagement section (62b) engages a first engaged section (51) by means of a closure prevention device (60), and the closing operation of an opening/closing body (10) is braked. A space (S) is secured that neighbors the end surface in the width direction of the opening/closing body (10) and is contiguous in the opening/closing direction of the opening/closing body; the space (S) is encircled in the opening/closing direction of the opening/closing body by means of the end surface in the width direction of the opening/closing body (10), the guide rail (30), and a support member (40); and the location of engagement/disengagement of the first engaged section (51) and the braking engagement section (62b) is disposed in the space (S).
    • 本发明提供一种打开/关闭装置,其具有用于阻挡制动接合部或与物体等的锁定接合部的接触的结构,因此可以防止导轨的周边变得 通过结构更厚。 在打开/关闭装置中,制动接合部分(62b)通过防闭锁装置(60)接合第一接合部分(51),并且制动闭合主体(10)的关闭操作。 固定在开闭体(10)的宽度方向上与端面相邻的空间(S),并且在打开/关闭体的打开/关闭方向上相邻; 所述空间(S)通过所述开/闭体(10)的宽度方向上的端面,所述导轨(30)和支撑构件(30)被包围在所述开闭体的开闭方向 (40); 并且第一接合部分(51)和制动接合部分(62b)的接合/分离位置设置在空间(S)中。

    • The present invention discloses a mechanism (100) particularly suitable for use with lifting systems of sectional doors comprising at least a pair of independent main bodies (120), each provided with a cavity (190) and conjugate profiles (130) operatively associated with one another formed on a portion of lateral surface of said main bodies (120). The remaining portion (140) of said lateral surface of said main bodies (120) is arranged for winding of lifting cables of said lifting systems; there is also a rotating shaft (150) for each main body (120) housed in said cavity (190); an elastic member (170) connected to said shaft (150) and to a surface (192) of said cavity (190); and an overrunning mechanism (180) operatively connected with said shaft (150). The disclosed mechanism more particularly comprises an elastic member (170) which is under full load when the sectional door is closed, and is fully released when the sectional door is fully open, and the relief curve of said elastic member (170) is proportional to the weight vertically exerted by said sectional door, said weight being variable along the vertical during the lifting operation of the door, the weight of the already lifted door portion being supported by horizontal guides (230) and no longer by said elastic member (170).
    • 本发明公开了一种特别适合用于具有至少一对独立主体(120)的分段门的提升系统的机构(100),每个主体具有空腔(190)和与一个可操作地相关联的共轭轮廓(130) 另一个形成在所述主体(120)的侧表面的一部分上。 所述主体(120)的所述侧表面的剩余部分(140)布置成用于卷绕所述提升系统的提升缆索; 还存在用于容纳在所述空腔(190)中的每个主体(120)的旋转轴(150); 连接到所述轴(150)和所述空腔(190)的表面(192)的弹性构件(170)。 以及与所述轴(150)可操作地连接的超越机构(180)。 所公开的机构更具体地包括当分段门关闭时处于满载下的弹性构件(170),并且当分段门完全打开时完全释放,并且所述弹性构件(170)的释放曲线与 由所述分段门垂直施加的重物,所述重量在门的提升操作期间沿垂直方向可变,已经提升的门部分的重量由水平引导件(230)支撑,并且不再由所述弹性构件(170)支撑, 。
