Abstract

The invention relates to winding closing systems. The device for actuating winding closing systems is of the type comprising a winding shaft placed outside a joinery element, driven by a winch controlled by a rod actuated from inside; it comprises an element 3 passing through the joinery element, articulated to the winch 4 by a simple cardan joint 2, and to the rod 6 by a double cardan joint 1 fastened to the inner face of the joinery element. Application to winding closing systems for renovation or restoration.

Description

The present invention relates to a device for operating roll-up closures, and more particularly a device allowing the operation of roll-up closures installed during a renovation or rehabilitation.

In the field of closures for the estimate, it is often necessary to set up roll-up closures in relatively old constructions which were not designed to receive shutters or blinds placed outside the bays, or any other roll closure. These renovation or rehabilitation operations therefore raise problems of fitting closures mainly at the level of the drive devices, generally consisting of a winch mounted at the end of the winding axis of the closure that it entails, and operated by a rod or strap.

To place a roll-up closure in an existing construction, it is necessary to drill the joinery either in the upper cross member or in the upper part of the side frames, which is a delicate operation, due to the little space left by the pig , on the one hand, and risks of deterioration of the joinery which could lead to leaks, on the other hand.

Generally, the position of the axis of the movement reference piece located inside does not coincide with the axis of the winch because French windows leave only a small pig usually between 0 and 30mm and must be able to open inward without being hampered by the mechanism.

The devices currently used are not satisfactory because they are fragile and anti-mechanical.

The present invention relates to a device for operating roll-up closings which is particularly suitable for renovation and rehabilitation operations, avoiding the drawbacks of current systems and operating satisfactorily.

The device for operating roll-up closures according to the invention makes it possible to set up closures such as roller shutters and blinds outside the bays of old buildings and to effectively ensure the opening and closing maneuvers even when the joinery is not suitable for such closures.

The device of the invention ensures the operation of winding closures of the type comprising a winding pin placed outside a carpentry, driven by a winch controlled by a rod actuated from the inside. According to a main characteristic, it comprises an element passing through the joinery, articulated to the winch by a simple universal joint, and to the rod by a double universal joint fixed on the interior face of the joinery.

The double gimbal ensuring the articulation of the control rod to the connecting element articulated to the winch is designed to allow the winch to be offset relative to the point of passage of the connecting element in the joinery without affecting the proper functioning of all. The angle thus authorized can be of the order of 300.

In addition, a large clearance is allowed in the vertical plane, allowing, in particular, maneuvers in a horizontal plane. The inclination with respect to this horizontal plane is possible very simply in a displacement at an angle of the order of 450.

The characteristics and advantages of the invention will appear in more detail in the description below relating to a preferred embodiment, with reference to the accompanying drawings, which represent:
Figure 1: a schematic perspective view of the device
for operating the following winding closures
the invention.

Figure 2: a side view of the device of Figure 1.

Figure 3: a top view of the device of Figure 1.

As shown in FIG. 1, the operating device according to the invention consists of a double universal joint (1) and a single universal joint (2), connected together by an actuating connector (3), in rotation, the primary shaft of an operating winch (4) driving, in turn, in rotation, the winding tube (5).

The connector (3) is articulated to the control rod (6) by the double cardan joint (1), the case of which is fixed to the interior face of the joinery.

As shown in Figure 2, the connector (3) can be substantially horizontal, or occupy an inclined position, up to an angle shown in Figure 2 corresponding to about 450. It is therefore possible to place the winch at levels different from the fixing of the double universal joint (1), the connector (3) being orientable at an angle of 0 to 450 relative to the horizontal.

 Figure 3 shows that the double universal joint (l) can be offset laterally with respect to the joint (2) and the winch (4). The offset A thus obtained corresponds to a maximum angle of the connector (3) relative to the axis of the winch, of approximately 300, the connector being orientable laterally at an angle of 0 to 300.

Furthermore, the design of this double toggle block is such that the relatively bulky mechanical parts do not protrude, which facilitates minimal drilling in the upper cross member of the joinery or on the side frame.
