Description

The invention relates to a locking device, according to the restrictive part of paragraph 1 of the claims, and to a set of parts of the device.

A locking device according to claim 1 is already known from EP 1 208 281 B1. It proposes the provision of locking elements in the form of a locking protrusion and a locking part or a locking element, of which one is located on the fixed frame and the other on the sash. In the direction of the seam surfaces, they are movable relative to each other, while, as a rule, the locking part is stationary, and the locking protrusion is movable. Due to this relative movement, it is possible to engage the locking protrusion and the locking part with each other. In the locked or engaged position, the locking protrusion extends behind the locking portion on the engagement surfaces that extend along the fold of the frame post and perpendicular to the fold surfaces. In accordance with this prior art, the locking part consists of a main body and an upper part covering it.

This known solution is aimed primarily at reduced wear of the locking protrusion, which is made in the form of a mushroom finger and interacts in the area of the narrowed shaft with a stamped rough lateral edge of the upper part and wears out after a certain time. Therefore, it is provided that the main body and the upper part are so coordinated with each other that due to this, the rod remains at a distance from the rough lateral edge, and the head of the mushroom finger rests on the main body. Practice has shown that these locking parts are difficult to clean and, on the basis of rough edges, can lead to injuries when cleaning. In addition, the solution is applicable exclusively to the locking protrusions in the form of a mushroom finger, although in practice also cylindrical and elongated locking bodies with and without a T-shaped cross section are used.

The basis of the invention is the creation of a low-cost locking device, which prevents the disadvantages of the prior art, and a set of parts of the device, which allows universal use.

The solution to this problem is carried out by implementing the features of the distinctive part of claim 1 of the claims in a locking device, according to the restrictive part of paragraph 1 of the claims. The corresponding set of parts of the device is indicated in paragraph 12 of the claims.

Due to this solution, which makes it possible to produce significantly more cost-effective locking parts, which should not interact with the mushroom finger, the upper part and the main body are also connected to each other in the longitudinal direction, and the corresponding longitudinal ends are open. Since these edges are not necessary for the closing function itself, the operational properties of the locking part do not change.

Other preferred embodiments follow from other claims. So, according to claim 2, the main body is made longitudinally symmetrical and has a through hole for a fixing screw in the middle, and the upper part covers the main body in a U-shape with fixation in the through hole area. This leads, along with material savings in the area of the locking surfaces, which are made as large as necessary, also to the fact that it is possible to further ensure the connection of the upper part with the main body, and the fixing screw fixes both the main body and the upper part.

In addition, it is envisaged that the upper part is mainly L-shaped, because due to this, in the area of the locking surfaces, the locking protrusion can interact with the main body and with the upper part. The advantage is provided, in particular, when the upper part and the main body are made of various materials.

When the main body and the upper part are in a straight line along the engagement surface, then with the cylindrical locking protrusion there is a relatively large locking surface, which reduces wear and promotes the use of cheaper materials.

It is also envisaged that the main body carries fixing or clamping protrusions that interact with clamping or fixing with the walls of the grooves or strips of the frame or sash extending along the seam surfaces. Perhaps the necessary preliminary installation of the locking part is facilitated by the fact that at first it can be fixed until it is finally fastened with a fixing screw.

The stability of the connection of the locking part with the frame or sash is maximum when the main body in the area of the through hole has a thickening, so that a reliable support of the fixing screw is provided.

To ensure a secure fit of the locking part, it is further provided that the main body in the through hole area has free space on the lower side. This ensures the placement of material distortions that occur when the fastening screw is screwed into the frame or sash.

It is especially economical to produce a locking device when the main body consists of a shaped plastic part.

When the upper part has an opening that is coaxial with the locking socket, which covers the upper part and is fixed in the main body, the connection of the main body and the upper part can be improved by using an additional mounting part.

In order to avoid a sharp edge on which dirt can accumulate, it is provided that the fastening part has a completion located on one straight line with at least the edge of the hole.

It is envisaged that the locking protrusion consists of a trunnion with a mushroom head, which has an end widened relative to the shaft, with the widened end covering the upper part from the bottom, at least in some areas, and for this the main body steps back relative to the upper part in the area of the locking surfaces . Due to this, the support of the locking protrusion on the main body and the upper part is achieved.

Of particular importance is the implementation of a set of parts of the device in which each main body and each upper part are made symmetrical in the longitudinal direction and have a through hole for a fixing screw in the middle, each upper part covers a corresponding main body in a U-shape in the zone of the through hole and is fixed here, and it is possible to coordinate each main body and / or each upper part.

Fig.7 is a section of a locking protrusion in cooperation with the locking part, according to Fig.6;

Fig - another example of the execution of the locking part, in isometric projection;

Fig.9 is a locking part, according to Fig.8, in side view.

Figures 1 and 2 show the locking part 1, which is composed of the main body 2 and the upper part 3. The main body 2 has a fastening collar 4 and a locking collar 6 that ends flush with the edge 5 of the upper part 3. The edge 5 and the locking collar 6 form along straight section 1, which runs parallel to the edge of the sash, the engagement surface 8. In this case, the main body 2 and the upper part are in a straight line along the engagement surface 8, without the protrusion of the main body 2 or the upper part 3.

While the engagement surface 8 at one end is bounded by the input bevel 9, at the opposite end it ends with a bulge 10. At the bulge 10, a coaxial through hole is provided that penetrates the upper part 3 and the main body 2 and serves to accommodate a mounting screw not shown here.

The main body 2 and the upper part are connected with fixation with each other, while fixing occurs, on the one hand, due to the fact that the main body covers the upper part 3 across the direction of the seam surfaces, i.e. also across the engagement surface 8. For this, the main body is provided at its longitudinal ends with extensions 11, 12 that extend beyond the length of the upper part 3 and, as shown in FIG. 3, are made higher than the base 13, so that the locking part 1 with the mounted upper part contains a flat upper surface without noteworthy protrusions.

In addition, from figure 3 it follows that the upper part 3 is made in comparison with the main body 2 with thin walls. It is preferable that the upper part 3 is made of a thin section of sheet metal, so that the recess 14 for accommodating the countersunk head of the fixing screw is made almost exclusively in the main body. In this case, the main body 2 protrudes with two diametrically opposite tongues 15, 16 into the hole 17 of the upper side 3. Since the tongues 15, 16 are oriented in the longitudinal direction of the locking part 1, due to this, the upper part 3 is placed with centering.

As shown in FIG. 4, the hole 18 in the main body 2 interrupts the mounting collar 4, so that the main body 2 in the area of the hole 18 has free space on the lower side. The holes 17 and 18 are concentric and form a through hole 19.

In this case, the main body 2, like the locking part 1, is made symmetrical in the longitudinal direction, and the through hole 19 is located in the middle along the transverse axis 20. The upper part 3 here covers the bulge 10 with the tab 21, so that the upper part in this section has U- a cross-sectional shape, while otherwise it has an L-shaped cross section. Due to this, the upper part 3 covers the U-shaped with fixation of the main body in the area of the through hole 19, respectively, of the bulge 10. The necessary locking action for this is achieved due to the fact that on the main body 2 there is a spring tongue 22, which is limited movable and spring the upper part to the longitudinal bridge 23, which extends approximately parallel to the foot 21. At the same time, the size of the web 24 corresponding to the thickness of the material of the upper part 3 provides a lower stop, which, like the foot 21, it is circled U-shaped in the thickening zone with 19 slats 25.

In addition, the upper part at its longitudinal end 26 captures the extension 11, 12 by the nose 27, so that also at the ends remote from the foot 21 the upper part 3 is secured. The main body preferably consists of a shaped plastic part, which has the necessary elastic properties and provides an economical manufacture.

In Fig. 5, for better visualization, only the locking protrusion 28, which interacts with the locking part 1 located on the fixed frame 29, is shown from the towing device. The locking protrusion is movably mounted along the fold, i.e. along line 30 above the lead device not shown. The locking protrusion 28 and the locking part 1 together form a locking element, with which you can fix the movable sash of the window or door relative to the frame 29.

However, in deviation from this, it can also be provided that the locking part is movably located on the leash, and fixed pins or the like are fixed to the frame 29. It may also be provided that the locking part 1 is fixed to the leaf, which is adjacent to the leaf, on which is attached a leash device with a locking protrusion 28.

In the shown exemplary embodiment, the locking part 1 is located on the fixed frame 29, and the locking protrusion 28 is on the sash. Both are installed with the possibility of movement relative to each other in the direction of the seam surface 31 along the line 30 and with the possibility of bringing into engagement with each other due to this relative movement. The locking protrusion 28 and the locking part 1 are enveloped behind each other in the engagement position shown in FIG. 5 by the engagement surfaces 8 extending in the direction of the seam surface 31 and the outer side surface 32, in this case, the cylindrical locking protrusion 28. The engagement surface 8 and the outer side surface 32 form perpendicular to the seam surface 31 and across the working surface.

6 and 7 show another exemplary embodiment of the locking protrusion 28, which has, as shown, in particular, in Fig. 7, the shape of the head of the fungus. In this case, the end 33 is expanded relative to the rod 34, or, with a cylindrical locking protrusion, provided with a large diameter. In this case, the locking part 1 in deviation from that shown in figures 1, 2 and 5 is provided with an upper part 3, which protrudes relative to the engagement surface 8. Due to this, the locking protrusion 28 rests on the upper part 3, as well as its expanded end 33 on the main body 2. For this, it is necessary that the protrusion of the upper part 3 relative to the main body 2 corresponds to the size by which the head of the mushroom-shaped locking protrusion protrudes at its end 33 relative to the diameter of the rod 34.

From figure 7 in connection with figure 2 it follows that the mounting collar 4 is designed to engage with the groove 35 of the frame 29. For this, the mounting collar 4 is equipped with a connecting bevel 36, due to which the main body 2 is conically expanded. Due to this, the main body 2 receives a clamping protrusion, which interacts with the walls 37, 38 of the grooves 37, 38 extending along the seam surface 31 with clamping or fixing. An improved clamping action is achieved by the fact that the fastening collar is provided with clamping ribs 39 (see FIG. 2) which protrude above the fastening collar 4. In addition to this or in addition to this, fixing elements can also be provided on the fastening collar which surround the back of the backing grooves 35.

To ensure the clamping action of the mounting collar 4, it is necessary that it is consistent with the appropriate shape and size of the groove. Therefore, in order to simultaneously take into account all possible options for the implementation of the locking protrusion, it is advisable to produce a set of parts of the device from various main bodies 2 and upper parts 3, which are made symmetrically in the longitudinal direction and have in the middle a through hole 19 (respectively, holes 17, 18) for the fixing screw 40, with this, each upper part 3 covers a U-shaped corresponding main body 2 in the area of the through hole 19, as indicated above, and is fixed here. Due to the combination of different, consistent with the size of the applied locking protrusions 28 of the main bodies 2 or the upper parts 3, it is possible to maximize the use of the main body 2 and the upper part 3.

In the exemplary embodiment shown in FIG. 7, the same main body 2 can be used when the locking protrusion 28 on the shaft 34 has the same diameter as the cylindrical locking protrusion 28 according to FIG.

In this case, it is again particularly preferable that the main body 2 is made in the form of a shaped plastic part, and the tool necessary for the manufacture of the main body 2 is made so that the fastening collar 4 corresponds to the component of the tool, which can be displaced relative to the rest of the main body 2 or replaced . Due to this, the area on which the upper part is attached can retain its shape, and it can be applied further.

However, it is particularly preferable to perform in conjunction with a cylindrical locking protrusion, according to DE 202005016417 U1, which is shown in Fig.5. In this case, the roller 42 mounted rotatably on the finger 41 forms an outer side surface 32. The roller 42 consists of a sleeve 43 and a tubular section supporting the sleeve 43, which is provided with a lip 44 at the free end of the locking protrusion 28. The sleeve 43 and the lip 44 together form the outer side surface 32. While the sleeve consists of plastic or plastic coating, the collar 44 is made of metal.

By making the locking part 1 and making the locking protrusion, according to DE 202005016417 U1, a pair of plastic-metal materials is created when the main body is made of plastic.

Figs. 8 and 9 show another exemplary embodiment. In this case, the upper part 3 is made essentially L-shaped and has a locking slot 45. Such a locking part 1 serves to interact with a T-shaped or mushroom-shaped (see FIGS. 6 and 7) locking protrusion. Moreover, the upper part 3 is also mounted on the main body 2, at least for transportation for mounting on the frame 29 or on the sash.

However, in deviation from this, in this case, it is provided that, in comparison with the aforementioned embodiments, the massive upper part has an opening 46, which is provided for receiving the fastening part 47, which covers the upper part and is fixed in the main body 2. This makes it possible to manufacture parts with less accuracy, since the connection is provided using a separate part - the mounting part 47. In addition, based on the massive execution of the upper part 3 there is no need to proceed b from the corresponding surmountable fixation resistance of the main body 2 and the upper part 3. Therefore, it would be necessary to provide additional fixing recesses or the like on the upper part, which make the surface uneven and make manufacture difficult.

In order to prevent the fastening part 47 from protruding above the upper part, it is provided that the fastening part 47 has at least one straight line with the edge 48 of the hole 46 or only a slightly protruding end.
