Description

- one -

The invention relates to a connecting rod mechanism. motor and to a door or a window with a mechanism of drive rod according to the preamble of claim 1.

The drive rod mechanisms of this type are already known. In EP 0823523 B1 it is disclosed a drive rod mechanism according to the preamble. The manual lever features an anchor plate on which fixing screws are inserted, which find threaded holes as counter-support in the drive rod mechanism housing. For counteract a deformation and thereby a limitation of the operation of the drive rod mechanism due to too tight tightening of the fixing screws, threaded holes are provided to be housed in bushings that can move in the housing axially with respect to the axis of the drill. The bushings are provided with flanges that are supported at the back or inside of the nerve to which the anchor plate is fixed.

With document EP 0674071 B1 it has become known a drive rod mechanism for mounting on a stringer of a leaf, the stringer consisting of a hollow profile, in which two threaded bushings for one manual lever are installed in the housing so that They can move transversely. Threaded bushings they can move outside the housing by means of a compression spring and, in a mounting position, in the one that mounts the drive rod mechanism, are attached to the housing by means of a closure. One time arranged the housing on the crossbar, the closure is released using a tool and the bushings move in

direction to the inner front surface, with respect to the enclosure, from the crossbar until they run into the nerve of profile to which the manual lever is fixed. If the manual lever is fixed to the front surface by means of fixing screws, it is thus avoided that there is a deformation of the drive rod mechanism if the fixing screws are tightened too much.

The aim of the invention is to achieve a fixation. of the manual lever which, unlike the state known in the art, can also be used to large distances between the mechanism housing and the front surface In this case, mobile supports do not

they are suitable due to the constructive size.

For

achieve East objective be foresee in a

mechanism

from connecting rod motor of the preamble from the

claim

one, the features from the part from

ID. Through the arrangement you get, in addition to a sure support of ..., since this one can bracing with the separation piece. Nonetheless, The manual lever is securely fixed.

In addition, the arrangement can also be used for manual levers in which the manual lever is fixed only indirectly to the anchor plate or not it is fixed to it, but it intervenes with a means of retention in the drive rod mechanism. They know each other manual levers of this type for example by the document 19601119 C2, document EP 0548378 B1, the DE 4238459 A1 or EP 0692592 B1. In these configurations, a retention element installed in a square spike, grab behind the pinion housed in the housing, so that the square is axially fixed at least in one direction. Between the anchor plate and / or the housing act on compression springs that

tend to move the manual lever to separate it from the housing, so that the retaining element that grab the pinion behind constitutes a counter-support for the bracing hand lever. In a configuration so an anchor plate can be attached to the crossbar protected against torsion, without making them visible the fixing screws.

Claims 2 to 11 show other advantageous configurations.

The opening is expected to consist of two overlapping holes, so that it can occur in a very simple way with tools easily available.

As an alternative, it can be provided that the opening is set to D-shaped or half-valued. Fit of D means here that in a part of the opening the edge extends in a straight line and this edge is followed two edges that extend at right angles to to the same and that end in a joint arc or in two arches with a straight junction section. The "D" can be in lying or vertical position and even being an image inverted

If the separation piece has on its side rear facing the drive rod mechanism, at least one rib that can be assigned to a recess of the housing, a fixation of the drive rod mechanism also in the direction longitudinal of the leaf renvalso.

Thanks to the longer dimension of the opening is in the area of a bottom of the crossbar, that extends perpendicularly to the nerve that forms the interior front surface, with respect to the enclosure, of the stringer and delimits a groove that extends along

of the nerve, this fund is not weakened by recesses or openings.

It is also provided that in the separation piece a limiting edge is provided that rests on the nerve, because in this way an alignment is achieved Simplified part separation.

In order to correspond to different dimensions of the crossbar profile, it is provided that in the piece of separation is provided a coupling device for detachable junction of a spacer.

The coupling device consists of a slit that constitutes at least one housing for the spacer This allows manufacturing comparatively simple device coupling

If the spacer is essentially Z-shaped and it rests on the separation piece with the part of the spacer protruding from the slit, the spacer is subjected to effort in dragging form.

If the separation piece is provided for minus two disposed accommodations displaced with respect to a plane of the part of separation, they are a great number of dimensions that can be covered with one piece of separation and a spacer.

Finally, it is also provided that the slit extend next to the limiting edge. Due of this, the support of the drive rod mechanism in the separation piece through the spacer is made at a point far removed from the renewal of the sheet. In this way, the housing has an ideal support.

The drive rod mechanism 1 shown in the Figure 1 shows a housing 2 and a mobile connecting rod 3. In the housing 2 is provided with holes 4 which, with a thread not visible here, they serve as counter-support for a manual lever or its anchor plate. Between the drills 4 there is also a drill 5. This drill 5 is planned for the passage of a polygonal spike of the

Manual lever not shown here. Casing 2 it presents an essentially shaped cross section of T, as can be seen especially in figures 4 and 5, and consists of two housing halves 6 and 7, between which houses a pinion 8 (figures 3 and 4). He gear 9 of the gear 8 gear in a gear 10 of the connecting rod 3, which is guided bilaterally in a groove 11 of the housing 2 formed by two ribs 12, 13 of the housing halves 6, 7 facing each other.

In this way, the connecting rod 3 is guided with possibility of longitudinal displacement. The pinion 8 has an opening 14 for engagement with the pin polygonal hand lever (figure 3) and a collar 15 which extends concentrically with respect to the opening 14 and allows the pinion 8 to be housed in the housing 2.

In the front view shown in Figure 2, which in the mounting position of the drive rod mechanism 1 is is in the direction of the manual lever, the nerve 13 It has a recess 16. In this one a blocking against tampering errors 17, which can move transversely to connecting rod 3 and presenting a stop 19. With the stop 19, blocking against errors of manipulation 17 stops the frame when closing the leaf and travels transversely in the housing 2. By cross displacement of the error lock of manipulation 17 is disengaged in a known manner a retention ratchet that is installed in the lock against manipulation errors 17. The block against handling errors 17 is configured as a slide that can move transversely to the connecting rod 3, is scrollable guided in the housing 2 and is pushed by a spring to its locked position.

In the housing half 7 located in the direction of the manual lever is provided a rib 18 that extends parallel to connecting rod 3 and at least along one part of the length of the housing 2.

Figure 4 shows the mounting situation. of the drive rod mechanism 1 on a crossbar 20 which is configured as a hollow chamber profile and from which The sheet is composed. It can be seen here that the nerves 12, 13 form two heels with which the housing 2 is rests on the C-shaped nerves 21, 22 of a groove guide 23. With central rib 24, configured further narrow, of its T-shaped cross section, the drive rod mechanism 1 is inserted into an opening 25 from bottom 26 of guide groove 23. Nerve 21 form here an outwardly oriented marginal ribbon and, in the example of realization, delimits the renewal of the crossbar 20.

The opening 25 can be made of different ways. It can be done for example by a process of milling made from the side of the renvalso. In the front face 28 of the stringer 20 are made additionally the opening 27 (hole 272) and the drills 271 and 273 (figure 7a), which are necessary for the pitch of the square spike and the fixing screws of the manual lever anchor plate, which is fixed to the front face 28.

However, it is preferable to make the opening 25 and drills 271, 272 and 273 through a process of die cut For this a tool of cutting in the guide groove 23 and thus part of the background 26. This is preferably done in width that results from the separation of the nerves from each other facing 21, 22. The opening 27 and the holes 271,

272 and 273 are also performed using a tool cut. To prevent damage to the front surface or the nerve 29 a matrix is placed on the back face 30 of nerve 29. This makes the marginal ribbon of the stringer 20, formed by nerve 22, and nerve 29 they must present a mutual distance 31 that allows introduction of the matrix. Together with nerve 32 it is created thus a groove 33 behind the nerve 29.

While Figure 4 shows the position of mounting of the drive rod mechanism 1, in figure 5 it can be seen how the drive rod mechanism 1 is attached to stringer 20. Mounting position designates here a state of the drive rod mechanism 1 that serves for mounting the drive rod mechanism 1 on the crossbar. Fixing the drive rod mechanism 1 here designates a state of assembly in which, although the drive rod mechanism 1 is fixed on the crossbar 20, no additional fasteners have been placed yet such as screws or the like, which for example serve also to fix the manual lever.

In the housing 2 a slide 35 is installed which, like blocking against manipulation errors 17, not shown in Figure 5, can scroll transversely to the housing 2, that is horizontally in the drawing according to figure 5. However, at the same time, the slide 35 is arranged in front of the lock against manipulation errors 17 and look out (towards the outside of the building). As you can see in figure 6, the cross section of the slide 35 It is essentially Z-shaped. A first arm 36 forms a U-shaped housing 37 at its free end and the second arm forms a guide arm 38, which is housed in housing 2 scrollable. In combination with

Figure 5 can be seen that the slide 35 hugs with the U-shaped housing 37 nerve 21. At the same time, the slide 35 is subjected by the springs 39, configured as compression springs, for the purpose of a force in the direction of nerve 21, so that the housing 2 is supported by the side facing the nerve 22 through nerve 18 and the lateral surface housing 40. The springs 39 rest on the slide 35 in two flanges which, for a simpler fixing of the springs 39, are provided with conical spikes.

Nerve 18 also grabs the nerve from behind. 41, which remains upright at the bottom 26 at opening 25 is created. Slider 35 is also located, at least in part, in the area of the transverse nerve 45 of the T-shaped cross section and, with respect to the central nerve 44 of the cross-section in the form of T, has at least nerve 18. In this way, in its mounted position according to figure 5, the mechanism of drive rod 1 is pushed by the springs 39 towards the right, in the drawing, until nerve 18 is supported. Comparing Figure 4 it becomes clear that, in the mounting position, slide 35 does not protrude, or protrudes only insignificantly, from the nerve central 44 and therefore can be entered without no difficulty in the space that is free between the nerves 21, 22 and the opening 25.

The guide arm 38 consists of two ribs 43 that they protrude in a U-shape from a base 42 and intervene in corresponding openings of the housing 2. At the same time, it is also foreseen that, in the position of assembly of the slide 35, its upper branch 45 of the U-shaped housing 37 is housed in a notch 46 of the heel or nerve 12. This way

ensures that housing 37 is aligned in relation with nerve 21, since the carcass 2 rests on it with the nerve 2.

A fixing pin is indicated in figure 6 47, which features a widened head 48 and a stem 49 thinner. In the slide mounting position 35, the rod 49 is in a bore 50 of the connecting rod 3 and goes through the latter and a recess 51 of the housing 2 and finally fits into a hole 52 of the slide

35. In the mounting position of the slide 35, the drills 50, 52 extend concentrically, so that the stem 49, whose diameter is adapted to the drills 50, 52, hold slide 35 in position represented in figure 4.

Mounting the drive rod mechanism 1 in the Stringer 20 is performed as follows. In first instead, the opening 25 and the opening 27. The mechanism of drive rod 1 in opening 25. This operation is performed in a direction 55 (figure 4) perpendicular to the Renvalso surface. The drive rod mechanism can be attached to adjacent cranks at the same time, not shown here, placed in the guide groove 22 with the possibility of longitudinal displacement. For it screws 56 are used that run through crank holes 57 3. Once the heels or nerves 12, 13 rest on nerves 21, 22, can remove the fixing pin 47, which maintains the slide 35 in its mounting position. The slide is pushed by the springs 39 out of the housing 2 and embraces the rib 21 of the stringer 20. The rib 18 is supports instead the height of the opening 27 in the

profile nerve 32. This support is performed misaligned next to the opening 27.

So, once the fixing pin is removed 47, the drive rod mechanism 1 is fixed and is no longer You can leave now. The slide 35 therefore constitutes a retention means with which the connecting rod mechanism Drive 1 is fixed to the crossbar. To disassemble the drive rod mechanism the slide 35 must be pushed back and then you can also make sure by the fixing pin 47.

Previously mentioned since the tree motor, in the form of a polygonal lever tree manual, through the opening 27 of the stringer 20 of the sheet. At the same time, it is also planned that the opening 27 is crossed by at least one element of fixing 60 of an anchor plate 61 of the lever manual and that this fixing element 60 has a counter-support in the form of a threaded drill 62, either in the housing 2 or in a separation piece 63, which enter the space that is free between the nerve 29 and nerve 32. The use of separation piece 63 is convenient if distance 31 becomes so large that there is the possibility of warping of nerve 29 when squeezing the fixing elements 60. The separation piece 63 offers the fasteners 60 a counter-support which can be directly braced to nerve 29. Thank you to this can be dispensed with a support of the mechanism of drive rod 1 with respect to nerve 29.

According to figure 6, it can be provided place directly on the anchor plate 61 ones support projections 64 which, through the opening 27, reach the housing 2 and are housed in openings of it. These secure the housing in

longitudinal direction However, this requires a adaptation of anchor plate 61 to different profiled, as indicated in figure 5 by means of the modified positions of profile section 65. 65 ’. Since, at the same time, the anchor plate 61 must also adapt to different colors of the sheet, it turns out advantageous the configuration with the separation piece 63, since this avoids multiplying the forms of realization of anchor plate 61. Next, describe the different embodiments of the separation piece 63.

The anchor plate 61 has recesses of retention, which extend radially and whose retention projections are assigned a disk of retention that is installed fixed against rotation in the square tree, not shown here, of the lever manual. In this way a configuration is also possible in which an element is installed in the square tree of retention that grabs behind the recess 14 of the pinion 9. Thus, the spring that extends axially with with respect to the square tree it can serve exclusively to brac the manual lever. The functions of lever retention are independent of this and by therefore easier to adapt.

In figure 7 a first is represented mounting situation. As can be seen in Figure 7a, the beam 20 is provided with three holes 271, 272 and 273, which are on a joint central axis and are placed at the bottom of the bottom 26 of the guide groove

23. The central hole 272 is used to pass the spike polygonal hand lever while drills 271 and 273 are used to fix the fixing screws found in the threads of the holes 4 the counter

support already mentioned at the beginning. In figure 7a) it can be seen that both the bottom 26 and the nerve 32 that extends transversely to the direction of the drills are eliminated, at least in part, by drills 271, 272 and 273. However, it is necessary to eliminate at least the section of the bottom 26 that is between drills 271 and 273. This can be done for example by a milling process carried out from the side of the renvalso.

Previously mentioned as the recesses and the necessary drills can be made through a die cutting process. To do this - as I know mentioned above - it is necessary to enter a matrix that prevents warping and deformation of the nerve 29. To this end it occurs in a first stage of work the opening 25 by inserting a cutting tool perpendicular to the direction of the renvalso. Not here it is possible or necessary to use a matrix as suffridera, since, once installed the mechanism of Drive rod, the opening is largely covered. Therefore a collapse can be overlooked inevitable from the edges of the opening. Since, in addition, the opening 25 has a corresponding width approximately to the separation of the nerves 21, 22, the background 26 is sufficiently reinforced by these nerves 21, 22 and the marginal slats 65, 66 that extend perpendicular to the renvalso, so that it is not possible a fall in the guide groove 23.

To bridge distance 31 or 77 previously described (figure 5) the separation piece is provided 631, which is represented in Figure 7d in a view front, a side view and a rear view. This separation piece 631 presents, on its back side

oriented towards the drive rod mechanism 1, two outgoing ribs 67, 68 that can be assigned recesses 69, 70 (figure 2) of the housing 2. These ribs 67, 68 produce a fixation of the mechanism of drive rod 1 along guide groove 26. A central opening 71 allows the passage of the spike polygonal.

Figure 7f) shows that the piece of separation 631 rests on the one hand on nerve 29 and on the other hand in housing 2 and bridges distance 77 between nerve 29 and housing 2. To achieve a fixing the separation piece 631 to the blade is also provided an extension as a hook 72. This embraces the edge of the drill made in the nerve 32, which extends concentrically to hole 272. Al same time, the extension grabs the bottom 88 of the slot 33 below. In this way, the piece of separation 631 is fixed to the crossbar 20 although it is not Mounted no drive rod mechanism 1.

In the embodiment shown in the figure 7b) the same separation piece has been used 631 in a variant in which the manual lever is not fixed with fixing screws, but without screws by by means of a manual lever according to document DE 19601119 C2, EP 0548378 B1, DE document 4238459 A1 or EP 0692592 B1. Thus, Drills for elements of fixing that could be introduced into the threads of the holes 4. As can be seen in figure 7b), the part 631 separator grabs from behind using its lugs by way of flanges 73 the side edges of the opening

27. Threaded holes 74 made in the piece of separation 631 are arranged so that they are located in

the area of the opening 27 and therefore can be accessed to them through the latter. To do this, in this exemplary embodiment, opening 27 is in the form of a D or of semioval. The line of greater length, and with it the larger dimension, of the D-shaped opening 27 is situated at the height of the bottom 88, which extends perpendicularly from nerve 29.

In the mounting situation according to figure 8 it is provided a separation piece 632 that is used in a variant. In this case, drills 271, 272 and 273 (Figure 8a) or the opening 27 are mainly made through a drilling process. In the way of embodiment according to figures 8b) and 8c), the opening 27 it is carried out by means of two overlapping holes 274, 275. The larger dimension of the opening 27 is also arranged here at the height of nerve 32. In this example, this it turns out that the centers of the holes are on the rib 32. The separation piece 632 also it is provided here with lugs 75 that overlap the edges of the opening 27. A central hole 76 serves for passage of the polygonal pin of the manual lever. Also here it is planned, analogously to the configuration of the separation part 631, which can fix an anchor plate 61 to the separation piece 632 by means of fixing screws. With this Finally, the separation piece 632 has holes threaded 74.

This configuration is specially designed for take into account different dimensions 31. In the piece of separation 633 is provided a device coupling 80 allowing a detachable union of a spacer 81 and separation piece 632. The coupling device consists essentially of a

slot 82 into which the spacer can be inserted 81 with a coupling section. The slit 82 of the separation piece 632 is sized so that it create two adjacent insertion positions. In the left insertion position according to figure 8f), the spacer 81 is fixed in a left housing 83, and in the right half of the figure in the housing right 84. Housings 83, 84 are molded of transversely symmetrical shape with respect to the slit 82, so that the spacer can be fixed on the four positions (according to figure 8f) represented in Figure 8f).

The part of the spacer 81 facing the drive rod mechanism 1 is asymmetric with respect to the slit 82. The spacer 81 has essentially Z shape and is supported by the spacer part 81 protruding from the recess 82 in the piece of separation 632, without exceeding the groove 82. In the 632 separation piece different planes are provided for each of the four possible positions of the spacer 81. That is to say the surfaces on which the spacer 81 is supported are arranged displaced with respect to plane 85 (figure 8d). Plane 85 is extends essentially transversely to the axis of the threaded holes 74 and parallel to the surface housing side 40. This achieves a dimension 86 different for each of the provisions of the spacer 81 shown in Figure 8f). So well, together with the possibility of suppressing the spacer 81, a total of five variants can be covered of distance 31.

The spacer 81 can also be manufactured as a preformed piece of plastic and its manufacture

result, correspondingly, simply and accurately. This also allows different manufacturing spacers that differ in dimension 86 (figure 8g), so that, in addition to the five mentioned possibilities, it is possible to cover other mounting situations by adding other spacers 81.

The spacer 81 supports the connecting rod mechanism drive 1 against the separation piece 632, as you can see in figure 8h). Since the connecting rod mechanism drive 1 is moved by the slide 35 so continue in the direction of nerve 22, it is supported by all modes on the crossbar near the guide groove 23, with what would only be to fear a warping of the mechanism of Drive rod at the bottom.

In the two embodiments according to the Figures 7 and 8 also provide that the piece of separation 631 and 632 has a limiting edge 87 that it rests on nerve 32. This simplifies the assembly of the separation piece 631 or 632. The slit 82, or an analogous coupling device, is extends, preferably parallel, to this edge limiter 87 and near it, so that the housing 2 it also leans at its furthest point from the nerves 21, 22

Another example of realization of a separation piece 633 as alternative to the configuration represented in the figure

8. Drive rod mechanism 1 is assigned the part of separation 633, which differs from the piece of separation 632 described above in which the lugs 75 are have replaced by an outgoing arm 90, which is supported by the nerve 29 with a flat surface 91. The very outgoing arm configuration 90 makes a

force acting on anchor plate 61 through the manual lever produces an active moment in the clockwise (in figure 10), which is transmitted by the outgoing arm 90 to the nerve 29.

The central hole 76 is also used here for passage of the polygonal pin of the manual lever. Analogously to the configuration described above of the piece of separation 632, the anchor plate 61 can be fixed to the separation piece 633 by means of some screws fixation. To this end, the separation piece 633 It has threaded holes 74.

Two lateral projecting arms 92, 93 of the piece of separation 633 grab the rib 94 of the groove of guide 23 below, according to figure 10. So that the piece of separation 633 can be introduced in the opening 25, the separation piece 633 and the drive rod mechanism 1 are adapted to each other. The ribs 67, 68 allow relative displacement in recesses 69, 70, so that, to introduce it into the opening 25, the separation piece 633 can be housed first in a cavity 95. To this end, cavity 95 is sized according to the measurements of the piece of 633 separation and has a depth that makes it possible accommodate the projecting arm 92. Then, inserting the fixing screws of the anchor plate 61, are

shifts

the piece from separation 633 in address to the

nerve 29 and leans on it.

To the

less two from the drills threaded 74 that

constitute

a counter-support for the screws from

anchor plate fixation 61 are in a plane with drill 76, so that the necessary clearance in the profile it is created by a drilling process of the two (or if any three) adjacent holes and

overlapping each other according to figure 8c. He threaded hole 74 located in the center can be used optionally and it is anyway under the nerve 22, in a free profile space.

5 When the nerve 94 is grasped below, the piece of separation 633 is secured against rotation. At exemplified embodiment, the piece of separation 633 is further supported with edge 96 in the edge of the opening 25, so that there is also here

10 a support. In the cavity 95 a segment 97 is arranged which extends concentrically to pinion 8, protrudes from bottom of cavity 95 and fits into a recess 97 that It is provided in the separation piece 633 and presents

15 a complementary form.
