Description

The invention relates to a length-adjustable force transmission device for a window, door or the like, which contains a first element and a second element, and both elements contain connecting means and are designed to be connected to each other in selected longitudinal positions.

Made in the form of a force-transmitting bar, the known force-transmitting device has two drive rods as the first and second elements, which can be connected by means of connecting means with the possibility of length adjustment. For this, one of the rods has a toothed bracket, and the other rod is equipped with a toothed end. The toothed end can be inserted into the toothed bracket in various selected longitudinal positions, so that a suitable adaptation to the dimensions of a draft window or the like is possible. Since the end region of one rod must be made in the form of a toothed end, the manufacture is correspondingly expensive and only a limited range of length adjustment is available, which roughly corresponds to the length of the toothed end.

The invention is based on the task of creating a length-adjustable force transmission device for a window, door, and the like, of a simple design and with an unlimited range of adjustment.

According to the invention, this task is solved due to the fact that the connecting means are made with the possibility of connecting to each other with the help of a connecting element, and the first element contains an installation hole as a connecting means, and the second element contains as a the connecting means is an elongated installation hole (in the form of a longitudinal groove) equipped with a system of teeth, while a connecting pin is provided as a connecting element, which contains a corresponding system of teeth, and the connecting pin is installed in the installation hole in a longitudinal position, and in elongated mounting hole by the engagement of the tooth system, which is determined selectively, and the corresponding tooth system to the longitudinal position. In this way, two elements are connected using a connecting element made in the form of a connecting pin. This pin passes in a predetermined longitudinal position through the installation hole of the first element, which is made in a simple way, and then enters the elongated, provided with a system of teeth installation hole of the second element, the tooth system of the elongated installation hole is connected with a geometric lock to the corresponding tooth system of connecting pin. To adjust the length of the force transmission device, the tooth system and the corresponding tooth system can be inserted into each other in different longitudinal positions. Therefore, the elongated mounting hole provided with the tooth system provides, when viewed in the direction of its length, different insertion possibilities for the connecting pin provided with the corresponding tooth system, so that according to the pitch of the tooth of the tooth system and the corresponding tooth system, the appropriate length of the force transmission device can be set . Since the first element requires a mounting hole as a connecting means, which is only produced in a very simple way, a very simple construction is obtained, because the first element has to be - if necessary - only cut to a given length and then provided with a mounting hole in order to be able to connection using a connecting pin. The connecting pin itself can be connected to the second element in different longitudinal positions, so that a constant range of longitudinal adjustment is always available, regardless of the length of the cut.

According to an improved embodiment of the invention, it is provided that the tooth system has at least one tooth, and the corresponding tooth system has a plurality of teeth. Alternatively, it may also be provided that the tooth system has a plurality of teeth and the respective tooth system has at least one tooth. To adjust the length, it is enough if only one tooth of the tooth system or the corresponding tooth system engages with several teeth of the corresponding tooth system or, respectively, the tooth system. If there are several teeth, appropriate interdental depressions are made between them, into which the tooth can enter, ensuring engagement.

Preferably, it is provided that the first element is a drive thrust.

The second element can be made, in particular, in the form of a corner switch. In this way, it becomes possible to connect the drive rod with the possibility of length adjustment with an angle switch.

The angle switch preferably has two arms, each of which is provided with a linear guide and a slider that moves in the linear guide, and the sliders are connected to each other by a deflecting means and at least one slider has an installation hole. The deflecting element is mainly made in the form of a flexible, however, rigid enough to transmit the tensile and/or compressive forces of the element, in such a way that it connects the slider of one arm with the slider of the other, located at an angle of 90" of the arm. The movement of one slider is transmitted at the same time to another slider. An elongated toothed installation hole is provided on at least one of the sliders, that is, this slider can be connected to the above-mentioned drive rod with the possibility of length adjustment, and the drive rod has an installation hole, and said installation hole is connected to extended mounting hole through the connecting pin.

In particular, it can be provided that at least one of the sliders is equipped with a locking bolt.

This locking bolt serves to engage a corresponding locking plate on the outer frame of a window, door or the like. The angle switch is located on the sash of a window, door, or the like, so that the sash can be closed (locked) on the outer frame with the help of a locking bolt.

The connecting pin has a longitudinal section that is generally circular in cross-section and is inserted into the mounting hole. The outer diameter of the longitudinal section fits into the installation hole, matching it in terms of size and shape, and thereby ensures a practically gap-free connection.

For axial locking, the connecting pin has a head at one end and at least one clipable projection at the other end. The head is located on the edges of the installation hole and thereby holds the first element across the direction of movement of the force transmission device. The same applies to the at least one clip-on projection that engages the second member. Thanks to this, both elements are held together, so that during the transmission of forces (line of transmission of forces) there is no lateral deviation. Thanks to the locking connection, which is provided by a protrusion that is clipped, the elements connected to each other for dismantling can be separated without complications and then connected to each other again.

The connecting pin has an almost rectangular in cross-section longitudinal section, the longitudinal sides of which are equipped with teeth of the corresponding tooth system. Alternatively, it is also possible that only one longitudinal side is provided with teeth of the corresponding tooth system. This substantially rectangular longitudinal section can be inserted into the elongated installation hole in the desired longitudinal position, the system of teeth and the corresponding system of teeth providing a suitable selected position of the connection.

The elongated installation hole has mainly longitudinal walls equipped with teeth of the tooth system.

In particular, it can be provided that only one longitudinal wall is equipped with teeth of the tooth system.

To facilitate the insertion of the connecting pin into the installation hole, it can be provided that the teeth of the tooth system and/or the teeth of the corresponding tooth system are provided with guide bevels (chamfers).

In particular, the connecting pin is made in the form of a steel pin. Preferably, it is provided that the slider provided at least with an adjustment hole is a zinc slider made by the method of pressure casting.

The drawings clearly explain the invention on one of the examples of its implementation, namely:

Fig. 1 example of the implementation of the force transmission device, shown in perspective,

Fig. 2 force transmission device in a three-dimensional image,

Fig. 3 slider of the force transmission device, shown in perspective,

Fig. 4 connecting pin of the force transmission device, shown in perspective.

Fig. 1 shows a perspective view of the corner switch 1 of the device 2 of force transmission for a window sash, door or the like. Angle switch 1 has two arms C and 4 located at right angles. Each arm 3, 4 has a linear guide 5, 6, in which sliders 7, 8 move accordingly.

The sliders 7 and 8 are connected to each other by a deflecting means, not shown, which is made in the form of a flexible element, so that the movement of one slider 7 or 8 is transmitted to another slider 8 or, respectively, 7. The angle switch 1 is made of two parts, while the dividing plane passes through the linear guides 5 and 6, so that the sliders 7 and 8 can be easily mounted or, respectively, inserted into the corresponding linear guide 5, 6. The locking bolt 9 is rigidly fixed on the sliders 7, which serves to interact with the corresponding closing plate, which is located on the outer frame of the window, door or the like. With the help of the locking bolt 9, it is possible, for example, to lock the sash, which has an angle switch, on the outer frame. Sliders 8 and 7 each have a connecting means 12, 13 made in the form of a mounting hole 10, 11, into which a connecting element 16, 17 made in the form of a connecting pin 14, 15 is inserted. The mounting holes 10, 11 have an elongated shape (in the form of a longitudinal groove), so that the connecting pins 14, 15 can be inserted in different longitudinal positions into the mounting holes 10 and 11.

Figure 2 shows a perspective view of the power transmission device 2 with the drive rod 18 as the first element 19 and the angle switch 1 as the second element 20, and the power transmission device 2 in the traction area 18 is shown in a three-dimensional image. In contrast to Fig. 1, which closes the bolt 9, located on the slider 8. The drive rod 18 has at its end 21 an installation hole 23, which serves as a connecting means 22, into which a connecting pin 14 can be inserted. For installation with The connecting pin 14 is inserted into the mounting hole 23 of the rod 18, in the longitudinal position, which is set by the mounting hole 23 on the rod 18, and then into the mounting hole 10 of the slider 8.

The slider 8 in Fig. 3 is shown in detail in a perspective view, and the slider 7 shown in Figs. 1 and 2 is made according to the slider 8. The longitudinal mounting hole 10 has a system of 24 teeth, which is formed by teeth 25 located on the longitudinal walls 26, 27 of the mounting hole 10. At the same time, the teeth 25 are directed perpendicular to the direction of movement in the linear guide 6 or, respectively, 5. Both the teeth 25 of the system of teeth 24 and the installation hole 10 have guide bevels 28 or, respectively, 29, facilitating the introduction of the connecting pin 14.

Figure 4 shows the connecting pin 14 in a perspective view. The connecting pin 14 has a head 30 at one end, which serves to axially lock or fix the connecting pin 14 on the slider 8. For this, the head 30 has an annular support surface 31, the head 30 of which in the assembled state rests on the rod 18. For the size of the outer diameter of the ring-shaped support surface 31 is made in such a way that the head protrudes beyond the edges of the installation hole 23.

Adjacent to the head 30 in the axial direction is a longitudinal section 32 that is circular in cross-section and serves for insertion into the mounting hole 23. For this purpose, the outer diameter of the longitudinal section 32 is selected so that the longitudinal section 32 enters the mounting hole 23, corresponding to it in terms of size and shape , and thereby provides an essentially clearance-free connection between the rod 18 and the connecting pin 14.

The axial longitudinal size of the longitudinal section 32 preferably essentially corresponds to the thickness of the rod 18, into which it must be inserted.

The longitudinal section 32 in the axial direction is followed, in fact, by a rectangular longitudinal section 33, the longitudinal sides of which 34 and 35 are provided with teeth 36 of the corresponding system 37 teeth. The longitudinal section 33 can be inserted into the elongated mounting hole 10 of the slider 8 in the desired longitudinal position, and the system 24 teeth of the mounting hole 10 and the corresponding system 37 teeth of the connecting pin 14 provide the corresponding selected position of the connection. To facilitate the insertion of the connecting pin 14, the teeth 36 of the corresponding system 37 teeth are also provided with guide bevels 38. The longitudinal dimension of the longitudinal section 33 of the connecting pin 14 is preferably shorter than the longitudinal dimension of the installation hole 10, so that the connecting pin 14 can be inserted into installation hole in different longitudinal positions.

At its end, located opposite the head 30, the connecting pin 14 has a number of protrusions that are clipped 39, which, when installed, are fixed on the slider 8 and thanks to this, hold together the two elements 19, or, respectively, the rod 18 and the slider 8, or, respectively, angle switch 1, so that no lateral deviation occurs when the forces are transmitted. In addition, the protrusions that are clipped 39 and the head 30 allow you to connect and disconnect the two elements 19 and 20 without complications.

The connecting pin 15 shown in Fig. 1 and 2 corresponds to the connecting pin 14 and is made, like the connecting pin 14, in the form of a steel pin 40. The slider 8 is made mainly in the form of a slider 41, made by the method of pressure casting with zinc In the connected state, the connecting pin 14 passes through the installation hole 23 of the rod 18 and then enters the installation hole 10 of the second element, or, accordingly, the slider 8, in a given or, accordingly, selected longitudinal position, while the system of 24 teeth of the installation hole 10, with a geometrical lock, is connected to the corresponding system of teeth 37 of the connecting pin 14. Since the connecting pin 14 and the installation hole 10, or, respectively, the corresponding system of teeth 37 and the system of teeth 24 can be inserted into each other in different longitudinal positions, it is possible to adjust the length of the force transmission device 2 formed by the first element 19 and the second element 20. The mounting hole 23 is made in a very simple way, so that a very simple design of the force transmission device 2 is obtained. When installing, the rod 18 - if necessary - is first cut to length, and then provided with an installation hole 23, in order to receive the possibility of connection with the help of a connecting pin 14, and regardless of the length of the cut, a constant range of longitudinal adjustment is available. - Mon! yo" Key sht y / () sk 7 - re "А A --- , 2 vyti ko that IN y y i I nn sh-y det y В
