The invention relates to a connector transom with made with the possibility of fixing on the frame profile of the lower base part and is made with the possibility of introducing a hollow cross-section of the transom and can be pinned there top of the Packed item, while the nozzle part and the base part are arranged one above the other, for connection installed caplease with geometric circuit, and configured to move relative to each other in the direction perpendicular to the longitudinal axis of the frame profile to the end position with stop and fastening it to each other through directed through the region of the clutch with geometric circuit parallel to the longitudinal axis of the frame profile of the connecting means, while the base part includes at least one completed roof perpendicular to the longitudinal direction of the frame profile shape ramp with an inclined rising in the direction of insertion of the Packed items in the rear, and in front of him obliquely sloping front section, which are both along each of their sides is limited by respectively passing up the side wall, with supplementary details provided associated with at least one shaped ramp made complementaria a roof-like shape and in the assembled condition of the adjacent base jumper which has a protruding down guide, the bottom of which is provided with a corresponding inclined part of the front of the plot figured ramp inclined part, which in the assembled state at least partially adjacent to the front section of curly ramp, and open up on the basic details of the guiding device, which is input directed to the side with geometric circuit, an outstanding appropriate way forward for supplementary details figure ledge.

Connector transom mentioned at the beginning of the kind known from EP 0569986 B1. In such connector transom both be due to his connection to the hollow profile can first be mounted respectively through parts of the connector and then connected with the respective frame structure, prevents excessive loading of the ends of the shaped straps transom. Assembly as well as disassembly of each parts with the corresponding hollow shaped bar can be carried out without problems, and this can be achieved more versatility in use. Also the connection of the two partial components with each other in their area of the connector with a positive locking allows you to connect both parts with each other through designed for relatively low load bearing, as is the connection with geometric circuit takes the largest part possible lateral separating forces.

However, the known connector transom connection of its two components is somewhat difficult, since nadhani supplementary details for base item two speakers from the latter in the direction slipped on easily connecting straps must be entered in appropriately performed on the front end to be nadhani attachment details connecting the grooves, which in practice is problematic, and already with a slight misalignment of the parts relative to each other when the insert may cause breaking of the bars. However, on the other hand, is an important two-point fixation of basic and supplementary parts in order to be able to carry heavy loads in the longitudinal direction of the profile of the transom.

In this case the invention is to provide improved and improved connector transom above-mentioned type so that the light mounting base and attachment of parts to each other can be achieved even with a small initial misalignment of components during installation and at the same time is also achieved large load capacity connector transom in the longitudinal direction of the profile of the transom.

In the connector transom according to the invention this is achieved due to the fact that both side walls in the longitudinal direction curly ramp extended beyond its directional NaClO is down but the front section, thus they form an upward and down the hole, and ahead in the longitudinal direction is provided by connecting them on top of the crossmember, which at its lower side, passes obliquely forward and downward, and also guide Packed items at its front end section in the assembled state at least partially comes under the lower side of the cross, however, he adheres to it with pre-stress compression, and adjacent to its front, sloping down to the plot figured ramp region based on a shape of a ramp.

The connector transom according to the invention mounted on the front, located on the side of the input end of each of the reference jumper, protruding obliquely downward guide by mutual insertion nozzle part and base part shifts are made between the two side walls in an elongated beyond the inclined declining plot figured ramp groove, until it reaches connecting the two side walls at their front ends cross and go under it with the application efforts. At the same time the corresponding guide rests with its lower side at a certain distance from the area going under the crossbar inclined declining plot figured ramp in the lower direction. Due to this, is Ozzano very effective and yet relatively easy mountable mounting device, which can be perceived significant dividing efforts in the direction of the transom, which is fixed to the density of full-time item.

Each specialist clear how he should take shape similar to the guide to make it when sliding down the reference jumper by decreasing the inclined front end section shaped ramp during installation when you reach the cross and the continued shifting movement with the application of effort has gone under the lower side of the cross. Since the crossmember is on the front end of the elongated beyond the front, inclined declining plot figured ramp section of the side wall, i.e. at a certain distance from the front end of this section shaped ramp, it means that the bearing guide on the guide rail occurs at some lever distance from the place in which the guide is attached under pressure to the underside of the crossbar. This has the advantage that during Assembly base part and a cap part guide, which is set in accordance with each curly ramp on the Packed items, while going under the crossmember is low elastic tilt relative to the end of the curly ramp that contributes to the elastic pressure of the elastic is th recoil.

With this arrangement according to the invention when mounted on each curly ramp interposer should not, as in the case known from the prior art connector transom, before reaching the end position with emphasis be entered in the corresponding receiving groove, which requires precise alignment of the non-engaged with each other details. Moreover, with the arrangement according to the invention due to the fact that the guide for sliding out under the bottom side of the cross member simultaneously causes the pressure (due to elastic deformation due to a certain size is exceeded, or an appropriately selected tolerances), automatically get the appropriate alignment between the guide and the crossmember as interacting parts, which are not even sensitive to small distortions.

Due to the fact that in the case of the invention on the front, extended beyond the inclined declining plot figured ramp section side wall apertures are formed both up and down, when installing, you also receive the ability to hook in the direction from the top to the front end (or front end) of each guide or guides), first under the crossbar on the base part, then the rotational movement of the top in the Rog this point of engagement to lock the nozzle part on the base part, and only the last part of the place to perform still needed a slight longitudinal movement of Packed items relative to the base part.

Thus, in the connector transom according to the invention is achieved insensitive even to the initial misalignment of the parts relative to each other and relatively quickly performed the installation and fixation of the nozzle details on the base part, due to the abolition of the slide rails on the base part and the corresponding receiving grooves on the nozzle details that must be entered each other when mounted, is formed structural simplification.

Particularly preferred variant implementation of the connector transom according to the invention is that facing the nozzle part of the surface of the base part lies in the same plane, while here, under the "surface" of the base part refers to the sum of all the top end surfaces of the base part in the form of the end surfaces of all the speakers up cross-sections of the wall.

One preferred variant implementation of the connector transom according to the invention is that at least one guiding device formed elongated against the direction of insertion of the Packed items beyond the rear, inclined addressed is the student section at least one shaped ramp side walls, open in the direction of the local end of the base part. This makes it possible when mounting the nozzle details on the base part not only to move in the first direction relative to the base part for insertion into the guiding groove, but also by means of the above-described rotational motion from the top to introduce shaped ledge in the guide groove by moving sideways.

Particularly preferably, on the same connector transom according to the invention on the base details install two spaced parallel to each other curly ramp, with each of them is guiding device. Thus is achieved at such low costs particularly stable connection when the base part and top part are connected to each other.

In a preferred improvement of the connector transom according to the invention with each guiding device on the bottom of the Packed items correlated appropriate, made in the form of a lath shaped protrusion, which due to its engagement with the educated guiding device guiding groove during movement of the nozzle part relative to the base part provides a lateral displacement of curved ledge.

Another preferred embodiment of the invention also lies in the fact that the upper side of each on rawsumer ledge Packed items are oblique to the direction of its insertion is down at an angle, greater than the angle of inclination of the underside of the crossbar on the base part. When retraction under the crossmember on the bottom thanks to the guide reference jumpers due to the higher inclination of the upper side of the latter relative to the bottom side of the cross member is achieved are necessary for the emergence of efforts to clamp the elastic deflection guide.

Similarly, preferably it may also occur due to other implementation guide due to the fact that it is the top side of the guide in the plane transverse to the plane of the frame connector transom made barrel-shaped convex upwards. Due to this also can be achieved is necessary for the occurrence of the desired pressure guide to the underside of the cross bar of the elastic deformation of the guide during installation.

In addition, preferably, if the connector transom according to the invention, a protruding obliquely downward guide on the bottom edge of your stickout made in cross-section rounded, so when assembling, first of all, when side dressing attachment details for base item by moving on curly ramp reference jumper, you receive the advantage in passing spark the certain angle sections.

The invention will be described in more detail hereinafter, in principle, as an example with reference to the figures. Shown:

Shown in the following figures example implementation of a connector transom according to the invention the same parts even on different shapes provided with the same reference symbols.

Figure 1-3 shows the connector 1 of the transom, which includes two separate parts, namely a base part 2 and the nozzle 3. Figure 1-3 core part 2 and supplementary detail the 3 shows in cross-section, namely, at different points in time of the Assembly process, thus the nozzle part 3 for Assembly moves laterally in the x direction, namely perpendicular to the plane of the frame. While figure 1 shows the position of the base part 2 and the nozzle part 3 at the beginning of the installation process, figure 2 - average time of installation, and figure 3 - in the final state of installation, with further individual figures will be discussed in detail.

From the image in figure 1 it is clear that the base part 2 has slightly shifted down relative to its upper end surface, passing again transversely, i.e. perpendicularly to the plane of the frame, curly ramp 6, which in cross section is made roof. First of all, it includes, when viewed in the x direction of the insertion nozzle part 3, rising obliquely in the direction x of the rear section 7 and falling obliquely forward and downward of the front section 8, sections 7 and 8 above are connected to each other through the parallel upper end surface of the base part 2 of the intermediate section 9.

On the lower side of the nozzle part 3, the appropriate place position is supporting the crosspiece 10, which has a complementary shape ramp 6, in this case a roof-like turned inside out a form that, as long as the ANO na 3, in the final mounting position overlaps curly ramp flush and relies on it for its entire length.

On the front in the direction of inserting the end of the reference jumper 10 integral with a support strap 10 is made the guide 11, which protrudes from the front end of the supporting lintel 10 in the x direction of insertion forward and sloping down, with the bottom 12 is inclined at an acute angle a to the x direction of insertion (compare with figure 4), which corresponds to the angle of inclination of the inclined front sloping plot figure 8 ramp 6 (compare with figures 1 and 2).

Support extension 11 at its front end bottom fitted curve g (figure 3), which is particularly favorable from the point of view of the transition guide 11 by a roof-like surface shaped ramp 6, with the guide 11 of its rounded, anterior lower part adjacent to the upper surface shaped ramp 6.

Curly ramp 6 is bounded on its two sides projecting upward side walls 13 and 14 (see this image figure 7), while the side walls 13 and 14 are at right angles to the surface sections 7, 8 and 9 roof-made curly ramp 6, namely vertically upwards.

The concept of "bottom" and "top" or "bottom" and "upper side" in this Contex is in principle used in the sense of that Packed item 3 is located at the top and the base part 2 is on the bottom, so that by means of "up" in the case of the base part 2 is the direction to the density of internal parts 3 or through the "down" if the density of internal parts is indicated by the direction directed from the nozzle part 3. Similarly, "down" in the case of the Packed items indicates the direction of the base part 2, and the up - direction from the base part 2 (respectively, relative to the state of the assembled connector transom).

Along with this, the "front" or "front" refers to a look at the location in the x direction of insertion, and the "rear" or "rear" refers to a look at the location opposite to the direction x of the insertion.

The side walls 13 and 14 each curly ramp 6 have a period b, which, however, does not necessarily have to be constant along the entire figure of the ramp 6. In the case of image 7, for example, it is seen that the side walls 13 and 14 in the rear section 7 figure ramps have a slightly longer period b than located further ahead of inclined walking down the section 8. This difference in the interval b between the side walls 13, 14 is obtained due to the fact that located, when viewed from the side of the middle line of the base part 2, then the outside of the side wall 13 in the region of the plot figure 9 ramp 6 to the th denotes the vertex area, bent to the side, and it thus leads to the widening of the gap between the side walls 13, 14 in the rear, up understanding of the plot figured ramp 6. However, the other side wall, as shown in the drawing, are made so that throughout forms a flat side surface, when viewed in the direction of curly ramp 6, and therefore does not bring any contribution to the expansion of the gap between the side walls 13 and 14. One could also easily imagine that the side wall 14 (or also only the side wall 14 has a lateral shift at some point in its passage, so that, as a consequence (or to) has been a change in the span of b.

As follows from the images in figure 1-4 or figure 6, the side walls 13, 14 are in the area of horizontal falling forward plot figure 8 ramp 6 not only to his front end, but continue for him. Formed their continuation of the groove in the forward direction (i.e. in the direction beyond the front end of the declining phase 8 figure ramps 6) is limited to the upper cross member 15, which there connects on top of each other, both end walls 13 and 14 and at its lower side, as shown in figure 1-4, enters the inclined surface 16, which, when viewed relative to the direction of insertion x passes obliquely. In this case the angle β, PR is doctitle, more than α, but at least equal to α.

As you can also easily conclude from 1 to 4, the front end of the inclined sloping plot figure 8 ramp 6, when viewed in the longitudinal direction of the side walls 13, 14, is moved forward (i.e., figure 2 right) on a line addressed to him from the front end of the cross member 15.

For mounting, as shown in Fig.1-3, supplementary item 3 is now on the top side of the base part 2 in the beginning of the rising of the rear section 7 figure ramps 6 front lower curvature r of the guide 11 and then movement in the direction of insertion x moves along the top surface, therefore, it rises up the back of the rising section of figure 7 ramp 6.

After reaching and passing through the vertex plot figure 9 ramp 6 is achieved position as it is shown in figure 2.

Upon further movement of Packed items in curly ramp 6 in the x direction of the insertion guide 11 moves along the sloping forward surface plot figure 8 ramp down 6 along its inclined surface, which also drops down and forward at an angle a (see figure 2).

Since the lower side of the reference jumper 10 Packed items are also inclined at the same angle α at its lower side is located at the front in the direction of the x stable the Oia area, this means that the guide 11 with its lower side 12 is a lengthening of the lower side of the preceding section reference jumper 10 and upon further movement in the x direction of insertion, according to the position according to figure 2, adhering to the upper side of the front section figure 8 ramp 6, glides along it down, until it reaches its freely protruding end, through which he further inserting movement of the slides farther down the angle of inclination α. As soon as he crosses the predetermined offset between the front end of the site figure 8 ramp 6 and the front end surface of the cross member 5, the guide 11 with its upper side comes into contact with the inclined lower edge 16 of the cross member 15 and still moves on its upper side along the inclined surface 16, so that the guide 11 with its front section to some extent overlaps the cross member 15 at its lower end 16.

Figure 3 shows the final Assembly position, in which the supporting crosspiece 10 all of its underside, which has a corresponding execution curly ramp 6 complementary, also a roof-like shape, fully secured to curly ramp closes her across the length and relies on it in the lower direction.

This guide 11 comes on the inclined lower side 16 of the cross member 15 at a certain length, which in the case of the image in figure 3 is about half the entire length of the inclined bottom surface 16 of the support cross member 15. Here's the guide 11 is in abutment contact with the bottom side 16 of the cross member 15, while the guide 11 is attached to the bottom side 16 of the cross member 15 with increasing pressure.

This increase in pressure can be done in various ways, as shown for the two options on a purely fundamental enlarged detailed images in figure 4, which show guide 11 shortly before his crowding on the inclined lower side 16 of the cross member 15.

Authentic lines indicate the shape of the upper surface 21 of the guide 11, in which the upper surface 21 essentially in cross-section inclined downwards at an acute angle γ. However, this angle is at a little more than the angle β, which is inclined bottom sloping surface 16 of the cross member 15, so that when the retraction guide 11 under the cross member 15 between its inclined lower edge 16 and the inclined surface 21 of the guide are forced conditions that cause the guide 11 when the charge on the inclined bottom surface 16 of the cross member 15 is elastically pressed it, and between them there is the contact pressure, which further Wuxi is foreseen due to the fact, at the same time advocating for the front end of the inclined section 8 curly ramp 6 area guide 11 is slightly elastically bent down around the end point of the section 8 figure ramps, as acting on this segment, there is no direct backwater guide 11 from below.

The achievements thus the final state shown in the picture 3.

Figure 4 shows another form of the shape of the surface of the guide 11, which figure 4 shows a dashed line.

In this form of execution the surface 21 of the guide 11 in the cross section is not straightforward, and is convex in the upward direction. During retraction under the crossmember 15 guide 11 guide 11 in the area of convexity elastically compressed from above, and thus achieved the desired application pressure to the inclined bottom surface 16 of the cross.

Due to the fact that the end walls 13, 14 in their extended beyond the front end of the site figure 8 ramp 6 area (inside offset (C) form open both up and down the slit, provided that, on the one hand, the guide 11 can be put on and brought under the cross member 15, and this also enables a certain elastic rotation guide 11 down.

The simultaneity is temporal is the formation of the slit side walls 13 and 14 also gives the opportunity when mounting the nozzle part 3, moving from above, can be introduced along the entire length of the slit between the side walls 13, 14 to the front seat of emphasis in the final Assembly state (figure 3).

As the inclined front declining plot figure 8 ramp 6 and its rear, the inclined rising in the x direction of the insertion section 7 (as well as the average vertex section 9) is bounded on both sides along the side walls 13 and 14, so that there is formed an open up slot, which is available throughout curly ramp 6.

When mounting the nozzle part 3 of the base part 2 in the rear in the direction x of the insertion section 17 of the reference jumper 10 on the lower side of the nozzle part 3, corresponding rear section of figure 7 ramp that is inclined correspondingly to the inclination of the surface of the plot figured ramp 6 on the lower side 18, is introduced into the formed side walls 13 and 14 and the rear section of figure 7 ramp groove 20 (7), while the rear section 17 of the reference jumper 10 its lower edge 18 will not fall on top of the rear section 7 curly ramp 6, as shown in figure 3.

This groove 20 forms on the base part 2 opened in the upper direction of the guiding device, in which you enter the rear section 17 of the reference jumper 10, which is down from the density of face-to-face part 3, and when this is m is sent with side flush side walls 13 and 14, until, finally achieved the final mounting position according to figure 3. In the rear section 17 of the reference jumper 10 is provided directed parallel to the longitudinal axis of the frame profile of the hole 19, which in the final Assembly state (figure 3) performed in the corresponding position in the base part 2 through all the sections of wall openings 19' form a generally aligned along the axis of the through hole, through which in the assembled state of the connector 1 of the transom by means of respective suitable components (e.g., mounting screws, mounting bolts, and the like) can be achieved fastening base part 2 on a cap part 3.

Thus, in the assembled state (figure 3 and figure 5) has a two-point fastening of the two parts 2 and 3 of the connector 1 transom, namely, on the one hand, through holes 19, 19' (inserted with the connecting piece and, on the other hand, through the interaction between the guide 11 and the bottom side 16 of the cross member 15.

As shown in the figures, both attachment points are made at a relatively great distance from each other, which is especially favorable for a hard landing between the base part 2 and supplementary item 3.

Figure 5 shows a cross section mounted on the frame profile 4 and the hollow profile 5 transom connector transom at sobran the m state.

Figure 6 and 7 shows a perspective representation of the Packed items 3 and base part 2, while 6 represents a side view rotated slightly Packed the items, and Fig.7 is a top view in perspective on an upper side of the base part 2.

Figure 6 and 7 shows that this connector transom are two parallel curly ramp 6, each of which is associated respectively protruding guide 11 on the nozzle part 3.

As follows from figures 1 and 2, the base part 2 on its upper side is made so that all upward of the cross-section of the walls, etc. their upper end surfaces lie in one common plane that is Exactly the same and all the lower end surface of the nozzle part 3, except protruding parts reference jumper (jumper) 10 and guide (guides) 11, also lie in a common plane E' (compare Fig.6).
