Description

The subject of the invention is a drive with a drive rod according to the preamble of claim 1 of the formula.

A similar drive with a drive rod is already known. Utility model DE 7107673 U1 discloses a drive with a drive rod, comprising a movable drive rod and a device or means that converts the rotational movement of the handle into the translational movement of the drive rod. The device consists essentially of a pivot arm, which at one end is in rotational connection with the shaft of the handle, and at its other end contains a leash mounted with the possibility of movement in the groove of the pivot arm, which is included in the link, kinematically connected with the drive rod. The device is located so that the pivot arm and the drive rod lie in parallel and lying with offset relative to each other planes. The axis of rotation of the pivot arm is oriented perpendicular to the flat side of the rectangular drive rod, so that the entire device can be placed in a flat socket housing.

The disadvantage is that the outlet housing is made relatively wide, and the drive rod is openly placed on the end surface of the sash. In the usual accessories with a drive bar, the latter is hidden in the sash fitment groove located on the fold edge. Because of this, however, the need arises to make cutouts in the sash suitable for housing or the device. This weakens the cross-section of the sash, and for some sash materials, for example, hollow profiles made of metal or plastic, it is possible only conditionally, since the cavities include metal reinforcements, or the processing of profiles is very difficult.

Similar implementations regarding this device are also disclosed in DE 2163350, DE-PS 1222819, DE 3545859 A1 and utility model DE 1984486 U. All these implementations relate to devices that place handles on the socket and, thus, are mounted on the end surface casement frame.

The basis of the invention is the task of creating a hidden drive with a drive rod, which would be especially easy to manufacture and would not require finishing work on the sash, and here, in particular, seamed edges.

It is possible to solve this problem by implementing the features of the distinctive part of claim 1 of the formula.

Due to the fact that the rotation axis runs across the direction of movement, and the link is perpendicular to the drive rod located along the folded edge, and the link goes partially above and below the drive rod, you can refuse large cutouts in the casement, and the device can be at least , partially placed in the existing gap between the sash and the frame.

One cutout can completely disappear if the wings 13 are V-shaped, and the leash 12 is made in the form of a rolling body installed without the possibility of turning on the pivot arm 10. It may also be provided that the lead 12 is in the form of a drop and is located so that upon reaching half the stroke of the actuator 1 with the drive rod, the tapering end 25 is placed in the sharp cutout 26 of the wings 13.

If the drive rod has a flat rectangular section, and the axis of rotation is oriented approximately perpendicular to the narrow side of the section, then the necessary structural space can also be reduced perpendicular to the folded edge.

Especially preferred may be a device in which the pivot axis is located in the plane lying in front of the fold edge. In this case, it is possible to minimize the amount by which the pivot arm protrudes as much as possible in the direction of the folded edge.

This is also advantageous when the conditions described in EP 0 505678 A1 are met. In this case, the middle axes of the rotation axis, on the one hand, and the drive axis with the drive rod, on the other hand, are offset with respect to each other. To compensate for axial displacement, an intermediate gear is provided in this case, which provides axial displacement compensation. If the axial displacement is only negligible, then this intermediate gear cannot be used due to the gears used. Other solutions (for example, WO 01/25576 A1) are suitable, however, for less displacement, but they still represent certain manufacturing costs. By placing the axis in front of the folded edge, i.e. in front of a folded surface, it is possible in many cases to refuse to use an intermediate gear. Known devices located in the socket in accordance with the prior art cannot be used here, since the sash profiles used are usually very narrow and / or to close the gap arising between the sashes, a slat is placed on which the handle must be installed.

Further, it may be provided that the pivot arm during its pivotal movement passes through a cutout in the drive rod. Due to this, basically, the processing of the drive rod may disappear, with the exception of the manufacture of the cutout. It is preferable, however, to provide the drive rod with a bend directed away from the pivot axis, since this creates sufficient structural space for securing, if necessary, the necessary parts on the drive rod, and the cutout, which is a weakening of the drive rod, can be reduced to a minimum.

In order that the drive with the drive rod can also be used with the usual leaf profiles, it is envisaged that the pivot arm preferably passes through a cover which closes the fitting groove on the drive rod on the fold edge. The overlay can be made due to this without complex bending.

To facilitate installation and reduce the penetration of dirt into the device after a certain time, it is provided that the device is placed in a housing that is configured to be fixed on the seamed edge. This achieves an attractive appearance of the actuator with the drive rod.

To minimize the cost of manufacturing or installing the window and the size of the required cutout in the sash, the housing is preferably located in front of the cover. In this case, the circumstance is used that the cover and the body section protruding in front of it after installation close the back of the drive, and the whole structure becomes invisible, since the device is made mechanically relatively simply. An additional cutout for the housing disappears, and the available structural space can be fully used to calculate the drive.

Due to the fact that the pivot axis consists of a polyhedron, which is rotatably mounted in the housing and rigidly connected to the pivot arm, an exact interaction is created between the polyhedron and the pivot arm, and standard handles can be widely used.

Other preferred embodiments of the invention are depicted in the figures, which represent:

- figure 1: actuator with a drive rod in a three-dimensional image;

- figure 2: actuator with a drive rod of figure 1 without a housing and with a polyhedron directed in the opposite direction;

- figure 3: section along the line III-III in figure 4;

- figure 4: drive with a drive rod of figure 1, a top view;

- figure 5: another example of a drive with a drive rod;

- Fig.6: section of the middle section of a double-leaf window or door.

For the drive 1 shown in FIG. 1 with the drive bar, the overlay is indicated by 2 and the drive rod 3 by 3. The drive 1 is used for mounting on a fold edge (not shown) of a window or door leaf. For this purpose, the folded edge has a hardware groove in which the drive rod 3 is placed and closed with a lining 2. On the drive rod 3 there are latches (not shown), which in the locked position can interact with the latches fixedly placed on the box.

The trim 2 in the built-in state is approximately flush with the fold surface of the leaf, and the actuator 1 protrudes in the area of the housing 4 behind this fold surface or trim 2. The housing 4 has threaded holes 5 into which handle screws can be screwed in to secure it. The handle further has, in a known manner, a multifaceted landing hole for accommodating the free end 7 of the polyhedron 6. By means of the handle, the polyhedron 6 can be rotated around the axis of rotation 8. The drive rod 3 has a flat rectangular section with a groove running along the back side, and the axis of rotation 8 is oriented approximately perpendicular to the narrow side of this section.

The drive 1 contains means or device for converting rotational motion into translational motion, the design of which is described below. At the end 9 of the polyhedron 6 is placed without the possibility of rotation of the pivoting lever 10 (figure 2). A rigid connection of the pivot arm 10 and the end 9 of the polyhedron 6 can be achieved, for example, by connecting with a geometric or material closure. The end 9 of the polyhedron 6 interacts with the end of the pivot arm 10, while the other end 11 contains a leash 12. The leash 12 is made in the form of an axle and enters the wings 13 of the guide part 14.

As can be seen in FIG. 3, the guide piece 14 is rigidly connected to the drive rod 3 and extends substantially perpendicular to the drive rod 3 and the cover 2. The drive rod 3 is provided for accommodating the guide piece 14 with a bend 15 directed from the pivot axis 8. In the bend zone 15, holes 16 are made for securing the guide piece 14 made of flat material, as well as a cutout 16. Through the cutout 16, both the guide piece 14 and the rotation of the rotation axis 8 rotate the lever 10. In the 90 ° position of the rotation axis 8, the rotation lever 10 is rotated also 90 ° relative to the image in Fig. 3, and the lead 12 lies on the lower end of the link 13. In this position, the pivot arm 10 and the leash 12 pass through the cutout 16. The pivot arm 10 also passes through the cutout 17 in the patch 3, as well as the guide part 14, which thereby acquires additional reference on the pad 2.

The bend 15 causes the cut-out 16 to be shorter in the longitudinal direction of the drive rod 3, since the pivot arm 10 only finds the drive rod 3 at a larger angle of rotation. This prevents excessive loosening of the drive rod 3. This also contributes to the double fixing the guide part 14 on both sides of the link 13, so that the guide part 14 as a reinforcing element introduces the resulting tensile and compressive forces, respectively, in the adjacent areas of the drive rod.

Figure 3 further shows that the pivot axis 8 is located in a plane lying in front of the folded edge 18 indicated here. In this case, the value 19 by which the pivot arm protrudes as much as possible in the direction of the folded edge 18 or is immersed in the casement can be minimized. Due to this, the hardware groove 20 indicated in FIG. 3 is required to be selected only slightly along the range 21 of movement. In some cases, when the pivot movement of the pivot axis 8 is bounded by an angle of 90 °, this cut-out can even be completely abandoned, since the holes necessary for the polyhedron 6 and the handle fixing screws to pass through partially cause the opening of the hardware groove 20.

The link 13 extends perpendicular to the drive rod 3, and the link 13 extends partially above and below the folded edge 18 and, respectively, the drive rod 3. Due to this, on the one hand, the value 19, as already mentioned, can be kept small, and, on the other hand, the value 22, by which the housing 4 extends beyond the lining 2 and the folded edge 18, can be reduced to a minimum.

Finally, it also follows from FIG. 3 that the housing 4, in which the device for converting rotational motion to translational motion is fixed indirectly through the cover 2 on the folded edge 18, preferably lies in front of the cover 2 or the folded edge 18. In this case, the body 4 closed on top by a cap-like lid, while the lining 2 forms the lower completion. After mounting the drive 1, the entire device is placed in the hardware groove 20, which is closed by a cover plate. This makes the entry of contaminants difficult.

With reference to FIGS. 1 and 2, it should again be pointed out that the pivot axis 8 consists of a polyhedron 6, which is rotatably mounted in the housing 4 and connected to the pivot arm 10 exclusively for pivoting. The rotational support of the polyhedron 6 necessary for this may consist in the simplest case of a sleeve mounted rotatably and axially fixed in the side wall of the sleeve body through which the polyhedron 6 passes, so that the polyhedron can, if necessary, lean on it.

In conclusion, it should also be pointed out that the cover 2 is provided in the illustrated embodiment, however, it is not necessary for the operation of the drive 1. The drive 1 can therefore find application also in such structures in which there are no covers, for example, in window fittings and aluminum doors with a lying open drive bar.

Figure 4, finally, it is seen that only trunnions with threaded holes 5 protrude laterally behind the housing 4. Since they no longer need to be inserted into the groove 20, they can be placed on the housing 4 from the outside and do not require any structural space inside enclosures 4.

All the described components of the actuator 1 are manufactured in a simple manner. The pivot arm 10 and the guide piece 14, as well as the drive rod 3 and the pad 3, can be economically manufactured by cutting out of sheet steel or rods, which is, in particular, particularly preferred for the strength of the pivot arm 10 and the guide piece 14. The housing 4 can be made in in the form of a molded part made of plastic or metal, since it, in any case, should take small efforts.

Figure 5 shows another example of the execution of the drive 1. Here, the link 13 has a substantially V-shape and, therefore, has a right half 13a and a left 13b. Due to the large, thus, the width of the wings in the direction of movement of the drive rod 3, the guide piece 14 is also made wider compared to the implementation of figure 3.

The leash 12 is made in the form of a drop-like or cam-shaped rolling body and is rigidly fixed to the pivot arm 10 (only partially visible). The tapering end 25 of the leash 12 is directed from the axis of rotation 8 and calculated, as well as aligned with the link so that it enters the sharp cutout 26 of the link 13 when the pivot arm is in its 90 ° position and, thus, approximately in the middle of the maximum move.

On the switching path, based on the starting position shown in FIG. 5, the lead 12 with its downward side directed in the drawing rolls around the right limit edge of the wings half 13a until the end 25 enters the sharp cutout 26. With further movement of the pivot arm, the lead 12 also turns out counterclockwise from the sharp cutout 26 and its upper surface in FIG. 5, it is adjacent to the downwardly pointed middle segment 27, which separates the backstage halves 13a, 13b.

As a result, the guide piece 14 shifts further to the right, and the leash 12 rolls around the right boundary edge of the left half of the backstage 13b until the leash 12 rests against the upper end of the half of the backstage 13b.

By dividing the wings 13 into the half 13a, 13b passing with an inclination, the required structural depth of the drive is further reduced, and the necessary cutouts, if necessary, can completely disappear.

In Fig. 6, the actuator 1 is located in the upright post 140 of the sash 141. The sash 141 is provided with a pretended plank 142 which covers the adjacent sash 143 from above, blocking it, the so-called shtulp mechanism, and closing the gap 144 between the sash 141, 143. To make the window attractive In appearance, the mock bar 142 is located on the front surfaces 145, 146 of the middle pillars 140, 147 that are visible from the inside of the room so that it lies approximately in the middle with respect to the overall appearance.

A handle 148 is located on the mock bar 142, in which a polyhedron 6 is located in the hole 149. The handle 148 is secured by a socket 150 in which the handle 148 is rotatably mounted.

It can be seen that the polyhedron 6 passes through the pretend strip 142 also approximately in the middle and lies, in general, in front of the folded edge 18 of the leaf 141. Thus, the axis of rotation 8 of the pivot arm 110 lies in front of the folded edge 18.

According to the selected arrangement, therefore, means for converting the rotational motion of the polyhedron 6 and the drive mechanism of the drive 1, as described, for example, in EP 0505678 A1 or WO 01/25576 A1, can disappear. The direct connection is therefore more cost-effective and reduces slippage, which is inevitable with a large number of mechanical joints, which leads to a decrease in the stroke practically made by the drive 1 with the drive rod.
