PATENT APPLICATION

Reckange / Mess I; i Operating mechanism for folding shutters i ==================================== η f! i .1 ΐί ί! 1 «j ί .1 / \% - 2 - s The invention relates to an operating mechanism for shutters, in particular window and door shutters, with which the shutters when the window is closed or the door is closed , can be operated from inside the house.

I Apartment windows as well as glass doors, as they are often intended as direct access to a garden, balcony, terrace, etc., are usually opened either in the dark or during the absence of the residents either by roller shutters or by shutters to prevent outside and unwanted access completed.

The opening and closing is mostly done manually, e.g. roller shutters can be actuated from the inside of the apartment by means of belts, while the associated glass door or window must be opened beforehand in order to close and open the shutters so that the shutters can be folded back and forth directly by hand.

It is particularly difficult to close window shutters because they are often stiff and at the beginning; the closing movement unfavorable leverage between | the operator's arm and the folding shutter.

The operator must also to release the locking; , mechanism and often also to grab the folding shutter «, leaning far out of the window, which is particularly the case with | bad weather is uncomfortable. Opening the windows | , in order to close or open the shutters, it naturally also has a loss of room heat in cold weather,. in the wake of what is undesirable at the given time or can be undesirably large.

î | ϊ

Devices have therefore been proposed and implemented with which a kind of remote control of the folding shutters is possible, i.e. opening and closing the same | , from inside the apartment with the window closed, as is possible with roller shutters.

i v - 3 -

The prior art essentially consists in the fact that a worm drive is used in these devices, which can be actuated from inside the home and is in operative connection with the swivel axis of the folding shutter. The worm wheel of the worm drive can be arranged coaxially to the mentioned swivel axis i , which is the simplest solution in terms of effort, or the worm gear is moved inside the masonry and an additional connection is made between the worm gear and the swivel axis of the shutter by additional gear pinions.

The disadvantages of using a worm drive for such shop operating devices are primarily its space requirement. Because a worm drive because of its; naturally high friction does not get along well without lubrication, a relatively complicated, grease- and oil-tight housing must be provided for this. This housing interferes with j its space requirement both in its arrangement directly on

Shop hinge, as well as when it is housed in masonry. In addition, in the latter arrangement on the worm wheel axis, a gear pinion is additionally to be provided, which meshes with the one attached to the shop hinge directly or via intermediate wheels. This naturally results in an additional space requirement, which is all the more annoying since the space required for this must be created within the masonry.

To avoid these disadvantages of the prior art, it is an object of the invention, based on an operating mechanism of the type mentioned at the outset, to propose such a mechanism which is simple in construction, inexpensive to manufacture and requires a minimum of space.

- 4 -! This task is carried out by an operating mechanism for folding shutters with the characteristics of the

Main features listed solved.

Embodiments of the invention are shown in the drawings and are described in more detail below. Show it:

Figure 1, the general arrangement of folding shutters in connection with an operating device;

Figure 2, the essential structural parts of the operating device in their basic mutual arrangement when the device is housed within the masonry to the side next to a door or window opening to be locked?

Figure 3, like Figure 2, but in a general view and with a folding shutter?

Figure 4, an embodiment with accommodation of the I drive mechanism within a window or door opening and loading of the folding shutter by a toggle lever between the drive mechanism and the folding shutter.

(1

Figure 1 shows the general arrangement of a folding; loading-operating mechanism. A (not shown) Λ *] power transmission mechanism makes it possible to convert the rotary movement l of a crank 6 into a pivoting movement of the folding shutters 8, 10 I, the crank movement | "on hinges 12, 14 with a hinged hinge part 12a, 14a on the hinged shutter side and a fixed wall side

Hinge part 12b, 14b acts.

'μ.; i a | FIG. 2 shows the top view of a first exemplary embodiment of the proposed operating mechanism, such as how one could be used in the case of FIG. 1.

j A crank 6 (FIG. 1) can be attached to a square 16 16-1. The latter then acts via a shaft piece 20 which is more or less long depending on the thickness of the outer wall 18 of the house, on the nut 22 of a movement thread mechanism 24, which is completed by a threaded bolt 26.

At its front end, the threaded bolt 26 carries a rack segment 28 which is in engagement with a first gear pinion 30. Via an intermediate wheel 32, a gear pinion 34 is actuated, which lies in the axis of rotation of the folding shutter (not shown) and is part of a wall-side hinge part 12b, 14b (FIG. 1). The bore 36 of the pinion 34 is square in order to exert a driving effect on a square bolt (not shown) which is part of the hinged hinge part 12a, 14a.

When the crank 6 is attached to the square piece 16 and when the former is turned, the nut 22 is imparted a rotary movement via the connecting shaft 20 and the non-rotatable bolt 20 is displaced in the axial direction. As a result, the toothed rack 28, which is firmly connected to the bolt 26, conveys the desired rotational movement to the wheel 34 for pivoting the folding shutter (not shown) via the wheels 30 and 32.

Lubrication between parts 28, 30, 32, 34 is not absolutely necessary, especially if these components all or only part of them, e.g. the wheels 30 and 34 consist of a plastic with good sliding properties, since there are no large frictional forces between the parts mentioned, such as e.g. occur with a worm drive, arise.

On the other hand, a desired lubrication does not pose any difficulties since, as can be seen, the rack 28 and the wheels 30, 32, 34 are housed in a common housing 38, which only needs to be filled with grease and by means of appropriate sealing measures between the hinged part on the flap side (12a and 14a in FIG. 1) and the hinge part on the wall side (12b and t | i 14b in FIG. 1, or 38a in FIG. 2) can be easily protected against the ingress of water.

The same applies to the nut 22 mounted in a housing 40 S, which, if desired, can also easily be greased.

; 2 clearly shows the small amount of space required and the structure of the proposed mechanism consisting of inexpensive parts.

! I The desired direction of crank rotation to open or! The folding shutters can be closed by a suitable choice of h. The sense of pitch of the movement thread 26 can be determined, just like the ratio between the shaft 20 and the pinion 34! Ü can be influenced in a simple manner by appropriate choice of the pitch of this thread 26.

FIG. 3 shows in a general manner the installation i of a mechanism analogous to that according to FIG. 2 into a masonry 118 next to a door or window recess 44. The hinge part 112a of a folding shutter 108 on the shutter-side side is acted upon here directly by an end pinion (not shown) with a driver bore 136 .

In contrast to this, FIG. 4 shows an embodiment example in which a locking mechanism 142 is placed on the window ledge or the door sill 46, a window or an I door opening 144, instead of being embedded in the masonry next to the opening 144, as is the case here is the case in Figures 2 and 3. In the embodiment according to FIG. 4, the hinge part 48 on the shutter side can no longer be actuated directly by means of a driver bore 236 in an I (not shown) end pinion of the remote control 142. a connecting lever 50 is therefore arranged between this end pinion and the folding shutter, through which the latter can be pivoted.

* - 7 -

The embodiment according to FIG. 4 is particularly suitable if emphasis is placed on the simplest possible installation or if there is not enough space within the masonry for this.
