Description

SUBSTANCE: invention relates to an adapter for transmitting torque for connecting a fitting gear transmission mechanism with a handle having first and second connecting zones.

Known connection sprocket fitting gear mechanism with a handle through a four-sided standard rod. If such a standard rod must be extended, then an adapter is required that has a first connecting zone for receiving one end of a standard rod and a second connecting zone made in the form of a standard tetrahedral rod.

Four-sided standard rods have a distance between the edges of about 7 mm and therefore provide the appropriate transmission of torque. The transmitted force is determined mainly by the interacting surfaces, i.e., the specific load that the sides of the tetrahedral rod have on the corresponding sides of the tetrahedral socket in the sprocket (driving gear wheel) of the fitting gear mechanism, on the one hand, and the tetrahedral socket in the handle, on the other hand, for manual actuation of the furniture transmission mechanism. On the one hand, the fittings equipped with a multitude of locking pins require relatively high torques applied to the handle, and on the other hand, the size of the cross section of such a tetrahedral rod is limited, since the details of the fittings and the handle cannot be made too coarse. Double-glazed windows or doors with a feigned strip, there is a wish to place the handle in the middle. The known devices for this average location have to go at great expense.

The basis of the invention lies in the task of providing the possibility of transmission by means of a rotary knob or the like, for example also by means of a motor drive unit, of the highest possible torque to the furniture transmission mechanism with a relatively small structural form. Further, the knob should be made with the possibility of location in the middle of the feigned bar, preferably without great expense.

This problem is solved, in principle, due to the fact that the connecting body contains a rod concave profile.

The adapter of the kind described above has a first connecting zone made in the form of a tetrahedral socket and a second connecting zone made in the form of a rod of a concave profile. The core of the concave profile is inserted into the appropriately fitted seat of the drive gear or sprocket of the fitting gear. A tetrahedral socket on the other side of the adapter serves to attach to the handle. The latter also has a tetrahedral socket, so that one end of the tetrahedral rod is inserted into the tetrahedral socket of the handle, and the other end of the adapter is inserted into the tetrahedral adapter socket. In the case of a tetrahedral rod, it is, in particular, a standard tetrahedral rod with a distance of 7 mm between the faces. The use of a rod of a concave profile with an adapter allows one to realize a similar in size or relatively small cross section and therefore a small structural form, the cross section, however, due to the selected profiling, can transmit very high torques. In any case, the rod concave profile with a smaller or similar in magnitude of the cross section relative to the standard tetrahedron can transmit at least the same magnitude of the torques, which ensures reliable operation of the adapter. The term "concave profile" or "rod concave profile" or "nest for a rod concave profile" should be understood as a device that has at least one, when viewed in cross section, a concave contour, i.e. the rod of a concave profile has at least one portion of the side surface in the form of an arched profile. Accordingly, the nest for accommodating a rod of a concave profile has a shape consistent with it, i.e., a corresponding convex profile surface of the socket for a rod of a concave profile fits to the concave surface of the rod of the concave profile. Due to the concave shape, the profile rod used here can also be referred to as a “fitted” (i.e., narrowed in the middle part) core rod.

In particular, it is provided that the second connecting zone is made in the form of a biconcave profile. Two, in particular opposite to each other, side surfaces of the core rod are made concave, i.e. the cross section of the core rod is narrowed in the middle part. Preferably, the concave profiling is mirror-symmetrical with respect to the middle of the profile.

According to one improvement of the invention, the peripheral surface of the rod of a concave profile is provided with two side surfaces opposite one another and provided with two end surfaces opposite one another. Side surfaces more end surfaces. Preferably, at least one side surface is made in the form of a concave surface. In particular, both surfaces are made in the form of concave surfaces. At least one of the end surfaces is preferably made in the form of a convex surface, in particular the surface of a portion of a circular cylinder. Preferably, both end surfaces are made in the form of convex surfaces, in particular surfaces of a portion of a circular cylinder.

In particular, it is provided that the length of the faces of the tetrahedral socket is greater than or approximately equal to the maximum diameter of the rod of a concave profile. Under the "length of the edges" should be understood the size between the two parallel walls of the tetrahedral socket. The maximum diameter of the rod concave profile occurs when determining the greatest distance between two opposite walls of a peripheral surface.

According to one improvement, it is provided that the adapter has a rod-like middle zone which connects the first and second connecting zones. The size of the cross section of the middle zone is preferably less than the maximum outer diameter of the tetrahedral socket and is greater than or approximately equal to the maximum diameter of the rod of a concave profile.

In particular, it is provided that the adapter is made straight along its axis of rotation, so that the axis of rotation of the tetrahedral socket and the rod of the concave profile coincide with each other.

Further, the invention relates to a rod-like connecting element for a torque transmission connection of a fitting transmission mechanism with a handle having first and second connecting zones, the first and second connecting zones being respectively in the form of a rod with a concave profile. The rod-like connecting element is carried out, in particular, by means of a rod of a concave profile, which, predominantly compared to a standard tetrahedral rod, can be made already, but, nevertheless, with the possibility of transmitting the same or even large torques, since the arcuate, adjacent to each other surfaces provide good transmission of effort.

In particular, the connecting element is designed as a solid rod of a concave profile, i.e. has a full concave profile of the same length and length throughout its entire length.

The invention further relates to a fitting transmission mechanism for a window, door or the like, comprising a drive gear (also called an asterisk) having a connecting element, which is connected to the handle or connected to the handle. it is executed in the form of a nest for a rod of a concave profile. Thus, the force is introduced into the drive gear through a connection with the rod of the concave profile, i.e. the rod of the concave profile enters the connecting receiving element of the driving gear and causes rotation.

In particular, the handle can be connected to the drive gear via an adapter or a rod-like connecting element, respectively, as described above.

Further, it is preferable if the handle is made so that the diameter of its neck is smaller than that of the handles with a standard tetrahedral socket (7 mm). Due to this, with the possibility of transmitting the same effort, or even when transmitting more torque, an attractive appearance and / or small constructive form arises.

Finally, the invention relates to an fitting gear mechanism or a handle for a fitting gear mechanism with a receiving hole for a connecting element, the receiving hole being made in the form of a slot for a rod with a concave profile. The connecting element is preferably also a part having a concave profile.

Depicted in FIG. 1 the furniture transmission mechanism 1 is made in the form of an expanding transmission mechanism and can be used, in particular, in double-wing pivoting windows without a central impost. When mounted, it is placed, for example, in a feigned swivel plate, and due to its special design, it occupies a position in which, despite the knob in the middle, compensation for the axial displacement or inclined position of the torque transmission section relative to the knob is not required.

The fitting gear mechanism 1 comprises a housing 2, in which a driving gear wheel 3 (asterisk) and a connecting gear wheel 11 are mounted around two parallel axes 4, 21 spaced apart from each other. The ends of two thrust rods 39 facing each other, 40 are directed into the housing 2 and installed with the possibility of axial movement in it. Depending on the actuation of the driving gear 3, the thrust 39, 40 moves in opposite directions. The actuation of the drive gear 3 occurs from to

- 2 009315 by the power of a handle (not shown), which is connected to the driving gear wheel 3 by means of the torque transmission section 49 '(Fig. 2).

As seen in FIG. 2, the housing 2 of the transmission mechanism consists of two interconnected halves 22, 22 ', which are provided inside with support grooves 14, 27 (FIG. 1) for the rotary support of the drive gear 3 and the coupling gear 11.

FIG. 1 each of the supporting recesses 14 is made in the form of a part of a circle for accommodating a corresponding, annular portion of the rib 80 of the driving gear 3. The axis of rotation 4 of the driving gear 3 is located from the thrust 39, 40 at a distance x from the side of the fold.

FIG. 5-7, the driving gear wheel 3 has a flange 3 ′ in the form of a circular sector, which is provided with teeth 6 and from which ribs 80 in the form of a ring section protrude from both sides, which are included in the assembled state into the corresponding supporting recess 14 of both halves 22, 22 'housing 2.

FIG. 1 on the case 2, two sleeves 40, 41 are fixed, which close the rods 39, 40. The traction 39 has recesses 7 for the driving gear 3 and recesses 10 for the connecting gear 11; Thrust 40 has notches 12 for the connecting gear 11.

Furnishing gear 1 operates in the assembled state as follows. When the handle (not shown) of the drive gear 3 rotates, its teeth 6 engage with the notches 7 of the thrust 39. Moving the thrust 39 causes the coupling gear 11 to be driven into rotation by the notches 10, resulting in the engagement of the teeth of the connecting gear 11 with the notches 12 of the thrust 40. Thus, both thrusts 39, 40 move in opposite directions.

FIG. 5 and 6 it is clearly seen that the driving gear wheel 3 has a connecting receiving element 44. The connecting receiving element 44 is made in the form of a socket 45 for a rod of a concave profile, i.e. it is a receiving recess or a through recess, the walls of which are made to receive a concave profile.

FIG. 8 shows a section of the drive gear 3 in the region of the socket 45 for a rod with a concave profile. It is seen that the nest 45 for the rod concave profile is made in the form of a nest 81 with an open edge. The open-edge slot 81 has two side surfaces 82, 83 that lie symmetrically with respect to the center line 84 and are mirrored with respect to it. Both side surfaces 82, 83 are convex; both have a radius of K.6. Both side surfaces 82, 83 are connected by an end surface 85 of the socket 81 with an open edge. End surface 85 has a concavity resulting from radius K3. The transitions between the end surface 85 and the side surfaces 82 and 83 are made along the radii K1. From the above, it follows that the width d of the socket 81 with an open edge in the zone between the two radii K1 is larger than in the zone crossing the axis of rotation 4, which is characterized in FIG. 8 wide 11. In general, the socket 45 for a rod of a concave profile acquires due to this a “fitted” shape, and the “waist” is located in the zone of the axis of rotation 4.

In order to connect the socket 45 for a rod of a concave profile with a handle (not shown), an adapter 46 (FIG. 2) is provided, which with its one end portion 47 is adapted to be connected without being able to rotate with the socket 45 of the drive gear 3, and the other end portion thereof 48 can be connected to a standard tetrahedral stem. The handle has for this a standard tetrahedral recess into which a standard tetrahedral rod is inserted, the other end of which is inserted into the tetrahedral socket 49, in particular the standard tetrahedral socket of adapter 46. The adapter 46 therefore forms a torque transmission section 49 ', through which the rotation of the handle is transmitted on the drive gear 3.

FIG. 2, the end portion 48 of the adapter 46 has a first attachment zone 50, made in the form of the already mentioned tetrahedral socket 49. The end portion 47 of the adapter 46 forms a second attachment zone 51, made in the form of a rod 52 of a concave profile, the cross-sectional dimensions of which are matched with the jack 45 of the drive gear 3. Further, it is provided that the length a of the faces of the tetrahedral socket 49 is approximately equal to the maximum diameter b of the rod 52 of the concave profile. The maximum diameter is due to the fact that it is measured between two opposite end surfaces 86, 87 of the concave profile of the rod 52 (length 1 in FIG. 8).

FIG. 2, adapter 46 has, between the first 50 and second 52 connecting zones, a middle, cylindrical zone 53 formed. Further, the first connecting zone 50 has a cylindrical peripheral surface. The diameter of the cylindrical peripheral surface of the middle zone 53 is indicated in FIG. 2 as the size b of the cross section. It is less than the maximum outer diameter of the cylindrical section of the first connecting zone 50 and is slightly larger than the maximum diameter b of the rod 52 of the concave profile. Thus, the adapter 46 is made stepwise. The axis of rotation of the tetrahedral socket 49 and the rod 52 of the concave profile coincide with each other, i.e. adapter 46 extends longitudinally in a straight line. The cylindrical peripheral surface of the middle zone 53 is provided with a circumferential groove 54. Further, the end surface 55 of the adapter 46 has on one specific side 56 a tetrahedral socket 49 marked 57 in the form of a radial groove.

Regarding the hole 58 of the housing, releasing the nest 45 of the drive gear 3,

- 3 009315 diametrically opposed to each other on the half of the body 22 are two reference elevations 59, 60. They serve to support with the ability to move the I-shaped retaining spring 61. Both bends 62, 63 of the retaining spring 61 are installed with the possibility of movement in the longitudinal grooves 64, 65 of the supporting elevation 60. If the adapter 4 6 with the rod 52 of the concave profile is pushed into the nest 45 of the driving gear 3 (FIG. 4), the retaining spring 61 moves out of its position in FIG. 2 to the position in FIG. 4, with the free ends of the elbows 62, 63 entering the receiving longitudinal grooves 66, 67 of the elevation 59, and the sections of both elbows 62, 63 entering the circumferential groove 54 of the middle zone 53 of the adapter 4 6 and fixing it against slipping, however, allow rotational movement of the adapter 46 .

Additionally or alternatively, it may be provided that the retaining spring 61, when the adapter 46 is not mounted, takes the position in FIG. 3, i.e. completely inserted into the longitudinal grooves 64, 65 and the receiving longitudinal grooves 66, 67, and then the adapter 46 is pushed in by its rod 52 of the concave profile into the socket 45. The previous circumferential groove 54 of the circumferential incident bevel 68 ensures that the springs 61, when pushed in, were unclenched and in the final pushed-in position were inserted into the receiving groove 54.

FIG. 8 that the nest 45 for the rod of the concave profile is made so that the adapter 46 can slide into the nest 45 only in two rotational positions, which are offset to each other by 180 °. The corresponding rotational position with the adapter 46 pushed in is visible from the outside by marking 47. This creates the desired orientation of adapter 46 in slot 45, which is in proper proportion to the orientation of the 56 sides of the tetrahedral socket 49 and provides the corresponding handle position. Also, this measure allows you to uniquely recognize the right or left stop.

FIG. 9 shows a section of a rod 52 of a concave profile. It has end surfaces 86,

87, which form respectively convex surfaces 88, 89. Between the two convex surfaces 88, 89, length длина is formed as the maximum size. Further, the rod 52 of the concave profile has two opposite side surfaces 90, 91, made in the form of concave surfaces 92, 93. With respect to the longitudinal center line 94, both the concave surfaces 92, 93 are identical and mirror-symmetrical. The same applies to both convex surfaces.

88, 89 with respect to the transverse centerline 95. The concave surfaces 92, 93 are marked with radii K8, K9. Both convex surfaces 88, 89 are located predominantly on the surface of a section of an imaginary circular cylinder with the center 96 of adapter 46. Center 96 can be surrounded by a small recess 97 on the end side 98 of adapter 46. Next, the rod 52 of the concave profile has two bevels 99 in the area of its end side 98 , facilitating insertion into the drive gear 3. The maximum distance between the two side surfaces 90, 91 is indicated by the width of the minimum distance indicated by. Due to the shape of the rod 52 of the concave profile in FIG. 9, a rod 100 of a biconcave profile arises. It can also be called the core of a bone-shaped profile or a “fitted” core bar.

The comparison of FIG. 8 and 9 shows that when inserting the rod 52 of the concave profile into the socket 45, both contours enter each other with a positive fit and exactly in shape, and it is not necessary that the socket 45 accommodates the entire profile of the rod 52, since due to the shape, namely the concave surfaces 92, 93, as well as the convex side surfaces 82, 83, has a back span that prevents the lateral divergence of the joint. However, extremely high torques can be transmitted. Thanks to the open-edge socket 81, the drive gear can be displaced very far out in the housing 2, so that a very large distance x is reached from the fold side (Fig. 1).

As an alternative to adapter 46, it can be provided that the handle has a socket in its neck, into which a rectilinear rod of a concave profile is inserted, which has another end into the socket 45 of the driving gear 3. This design can therefore be abandoned from the usual tetrahedral device.
