Description

The invention relates to a device, in particular to a loop for fixing in a groove with undercut in a metal or plastic profile of a window, door, etc. or their frames, with a first protrusion extending into the first undercut of the groove, and at least one clamping element having a second protrusion, which, when the protrusion is brought into the first undercut, is brought into the second undercut, opposite the first undercut.

A device of this kind is known from the German patent for utility model DE-GM 77 09 379. In this device, the clamping element has a cylindrical support neck mounted rotatably in the opening of the device corresponding in diameter to the support neck. On the side facing the groove, a clutch disc is provided on the cylindrical support journal, radially protruding like a cam. The hole in the device for installing the support neck is located at an angle relative to the groove plane, so that when the support neck is rotated, an edge protruding like a cam not only moves in the groove plane beyond the second undercut of the profile groove, but also has a second component of movement perpendicular to the groove plane, so that when turning, it immediately clamps in the second undercut.

True, fixing this device anywhere in the direction along the profile groove is possible by simply installing it in the desired location, for which the clutch disc must first be installed so that it does not protrude from the external contours of the device, and after installing the device it rotates through an angle of about 180 °, so that the part of the clutch disc, protruding like a cam, went into the second undercut. However, a disadvantage is found here that a specific clamping position for the clutch disc does not exist. So, for example, depending on manufacturing tolerances and stiffness of the profile, the clutch disc can go through the position of maximum clamping force at which a protrusion like a cam is at “top dead center”. Therefore, reliable installation of this device is difficult. In addition, sliding the device in the direction along the profile groove can cause the clamping element to scroll through the top dead center, as a result of which the clamping force is weakened, and the reliability of fixing the device on the profile is compromised.

Therefore, the invention is based on the task of creating a device that could be mounted on a profile in the same simple way as described above, but would provide the device with a more reliable installation.

This problem is solved in accordance with claim 1 of the claims of the device.

In the device according to the invention, the second protrusion in the approach position in the second undercut may be pressed against the surface bounding the second undercut from the outside. In other words, the device according to the invention is characterized in that the second protrusion in the first stage after installing the device on the profile is first moved to a position in which the protrusion enters the second undercut. In this well-defined position, the second protrusion in the next fixing step can be pressed against the surface bounding the second undercut from the outside. The consequence of this is a very definite state of clamping, which even external influences, such as vibrations, the displacement of the device in the direction of the groove, cannot weaken.

The clamping element acts in one of the preferred forms of the invention through the hole provided in the device.

The clamping forces necessary for reliable fixation of the device on the profile are particularly effective on the device when the clamping element directly or indirectly rests on the clamping surface provided in the device.

In one particularly preferred embodiment of the device, the clamping element is made of several parts, preferably two parts. In this case, it includes a part having a second protrusion and a second part resting on a clamping surface, both parts being connected to each other by a thread. Then, the movement of the second protrusion in the approach position to the second undercut in the direction of the surface restricting the second undercut from the outside is due to the fact that both parts are rotated relative to each other in the make-up direction.

To bring one part of the clamping element into rotation with respect to its other part, the part of the clamping element resting on the clamping surface may have means for engaging with a rotary tool, for example an internal hexagon. After this, the second part having a protrusion, in order to avoid joint rotation of both parts, which impedes the process of fixing the device, is preferably installed without the possibility of rotation.

However, an embodiment of the device is particularly preferred in which its second part having a protrusion has means for engaging with the rotary tool. Then, on the one hand, using the nozzle of the rotary tool, you can translate the protrusion into the second undercut, and on the other hand, if the protrusion is symmetric about the axis of rotation, clamp by rotating the part having the second protrusion relative to the other part.

To engage the rotary tool with another part, the part resting on the clamping surface preferably has an opening for the passage of the rotary tool.

However, the clamping process can be further facilitated if, when the other part is rotated, a part of the clamping element resting on the clamping surface will be installed without the possibility of rotation.

Structurally, this can be done due to the fact that a turnkey face is provided on the clamping element, which can kinematically be connected to a turnkey face of the device or profile.

If the clamping surface, which is particularly preferred, has a conical surface provided in the opening of the device, and if a corresponding counter conical surface is provided at the clamping element, then the clamping element can be designed so that it does not protrude beyond the outer surface of the device. The advantages of the device are also its particularly small dimensions, as well as proportionality and attractive appearance.

The surface by which the second protrusion in the approach position in the second undercut is pressed against the surface defining the second undercut from the outside is preferably conical. This embodiment, on the one hand, has the advantage that, to create a clamping fit, the second part of the clamping element can rotate relative to the first, and on the other hand, it transforms initially a point or linear contact (at the beginning of the clamping process) with a conical surface bounding the second undercut with of the outer side, to such a large surface load that the surface bounding the second undercut from the outside undergoes plastic deformation. As a result of this, the geometrical closure of the conical surface with the profile surface occurs, due to which the device is especially well fixed from sliding in the direction along the groove.

As already mentioned, the installation of the device according to the invention can occur due to the fact that the clamping elements, assembled in advance, are first set in a position in which it is possible to install the device and the first protrusion in the first undercut of the groove. After that, for example, using a rotary tool, the clamping element can be moved to a position in which the second protrusion enters the second undercut.

However, you can also provide means for pre-installing part of the clamping element having a second protrusion in the position of entry into the second undercut. In this embodiment, before installing the device, the part of the clamping element having a second protrusion must first be put in the desired position in the profile groove and fixed there. Then the device is installed, and the first part of the clamping element is inserted into the threaded mesh with the corresponding other part by rotation of one or the other part, and finally clamping is performed.

In one of the following preferred embodiments of the device according to the invention, part of the length of the clamping element, starting from the protrusion, is an external thread. An elongated hole is provided in the device, which, in the area corresponding to the position of the clamping element in which the protrusion enters the second undercut, has an internal thread corresponding to the external thread. In this embodiment, the installation of the device on the profile can be carried out by planting the first protrusion into the first undercut of the groove when the clamping element is located on the elongated hole where there is no thread. After the final installation of the device, the clamping element can be transferred in an elongated hole to a threaded section. As a result of screwing the clamping element over the threads of the elongated hole, the adhesion of the external thread to the internal thread and, ultimately, clamping can occur.

Particularly preferred is an improved version of this embodiment, in which part of the elongated hole without thread has a width less than the diameter of the internal thread. In this case, under this width, the section of the clamping element without thread is adjusted so that this element can move in the elongated hole in the longitudinal direction. If the free end of the portion of the clamping element without thread has a radially protruding edge, the outer diameter of which is greater than the width of the portion of the elongated hole without thread and less than the diameter of the internal thread, then the clamping element will not fail while it is in the portion of the elongated hole without thread.

In order to facilitate engagement of the external thread provided at the clamping member with the internal thread of the elongated hole, it is preferable to provide a springing member resting on the groove base plate at the end of the clamping member on the protrusion side. Due to this, the end of the external thread, facing the portion of the clamping element without thread, after installation of the device is pressed against the internal thread so that the rotation of the clamping element in the direction of screwing inevitably leads to adhesion of the threads.

Especially preferred for all forms of execution of the device according to the invention, if the first protrusion has a conical surface. As a result, the surface force acting from the side of the first protrusion on the surface, limiting the first undercut from the outside, also increases so that plastic deformation occurs, which leads when the device is secured to adhesion by geometrical closure.

Particularly large holding forces are formed when, what is particularly preferred, the conical surface is made on the head of a screw rotated from the outside of the device.

Even greater holding forces in all forms of execution of the device according to the invention are noted in those cases when the profile has another undercut outside the groove, and the device has another protrusion that goes into this undercut.

On figa-1d device, indicated by the position 100, contains a plate 101 of the base. In accordance with FIG. 1, it has a middle portion 102 bent downward by a step. The amount by which the middle section 102 on both sides of the step decreases relative to the end sections 103 is adjusted to the depth of the undercuts on both sides of the groove 104 of the profile 105, on which the device 100 should be mounted, so that the assembled form in accordance with Fig. 1a is the lower side of the middle section 102 rests at the base 106 of the groove 104, the lower sides of the end sections 103 on the outer surfaces 107 of the protrusions 110, 111 of the profile, forming undercuts 108, 109.

On the middle section 102 in its plane, a protrusion 112 is provided, facing the first undercut 108, to enter this undercut. The width B of the middle section 102 is adjusted to the gap between the profile protrusions 110, 111 so that the middle section 102 with the protrusion 112 inserted into the first undercut can go into the groove 104 of the profile 105 from the front.

The base plate has at the end portions 103 from the side facing the second undercut 109 elongated holes 113 extending transverse to the longitudinal direction of the groove 104, in each of which, in the longitudinal direction of the elongated holes, a corresponding clamping element 114 is mounted for movement. Each clamping element 114 comprises a threaded rod 115 made on a conical head 116, which in its shape approximately corresponds to the head of a countersunk screw. Between the conical head 116 and the threaded rod 115, turnkey faces 117 parallel to each other are provided, the distance between which corresponds to the width of the elongated holes 113. Due to the contact of the turnkey faces 117 with the edges of the elongated holes 113, the clamping element 114, which has completely entered the elongated hole 113, is protected from cranking. The arrangement and dimensions of the elongated holes 113 are selected so that with the maximum displacement of the clamping element 114 in the corresponding elongated hole 113 towards the center of the base plate 101, the edge of the conical head 116 can pass the profile protrusion 111, forming a second undercut 109. The elongated edges to the base plate 101 the holes 113 are so suitable that the conical head 116 part of its circumference comes into the second undercut 109.

A threaded hole is provided at each end portion 103 into which a latch 118 can be screwed in, the shape of which substantially matches that of the clamping member 114.

Both the clamping element 114 and the latch 118 for engaging with the rotary tool have recesses in the form of internal hexagons from the front side of the corresponding threaded rod.

The threaded hole 119 for installing the retainer 118 is located so that the conical head 120 of the retainer 118 part of the circle came into the first undercut 108.

A device 100 rests on the base plate 101, which in the illustrated embodiment consists of two hinge elements 121, 122 of the hinge on the frame. The fastening of the device 100 on the base plate 101 is carried out, inter alia, due to the fact that the device 100 has a threaded hole 123, into which the clamp 118 is also screwed and which corresponds to the threaded hole 119 in the base plate 101, being aligned with this hole.

In addition, elongated holes 124 matching the elongated holes 113 are selected in the device 100, so that the threaded rod 115 of the clamping member 114 also fits into the elongated holes 124, and the clamping member 114 has the above-described movement capability.

A clamping plate 125 is also provided for each clamping member 114, acting on the device 100 from the outside. The latter in the places of installation of the clamps 118 has openings 126, which serve to pass the rotary tool (not shown) to bring the clamps 118 into rotation. In addition, a turnkey hole 127 is provided in the portion of the elongated holes 113 and 124. Moreover, a section of a larger diameter is provided in this hole on the side where the clamping element 114 is located when the conical head 116 part of the circle enters the second undercut 109.

The keyhole-shaped opening 127 serves to mount the second portion 128 of the clamping member 114.

The second part 128 of the clamping element 114 has an extension 129 with an outer surface of cylindrical shape, in the center of which a threaded hole 130 is selected, corresponding to the external thread of the threaded rod 115. Again, the conical head 131 is again adjacent to the extension 129. The surface 132, corresponding to the conical surface conical head 116, is provided on the plot of the larger diameter of the hole 127.

Next, on the basis of FIGS. 1b-1d, the principle of operation of this device 100 is explained. As shown in FIG. 1b, in which the device 100 is shown at the beginning of the installation process on the profile 105, the clamping element 114, pre-assembled by screwing the second one onto the threaded rod 115 parts 128, in the elongated holes 113 and 124, is completely offset in the direction of the first undercut 108. In this position, the plate 101, when the first protrusions 133 formed by the conical heads 120 of the clamps 118 enter, into the first undercut 108 can be inserted into the groove 104 of the profile 105. When During the installation process, a certain backlash is created in the direction transverse to the longitudinal direction of the groove, which is large enough for another protrusion 137 provided on the device 100 to be inserted behind the protrusion 136 of the profile, which forms another undercut 135, outside the groove 104.

Upon reaching the position of the device shown in fig.1b, the pre-assembled clamping element 114 is translated into the position shown in figs, by moving it in the direction of the elongated hole, in which the second protrusion 134 formed by the conical head 116 of the clamping element 114 comes into second undercut 109. In this position, using a rotary tool (not shown), the second part of the clamping member 114 continues to screw onto its threaded rod 115 until the clamping member 114 reaches the position depicted 1D. As a result of the initial point or linear contact of the surface of the conical head 116 forming the second protrusion 134 with the surface 136 defining the second undercut 109 from the outside, when the second part 128 of the clamping element 114 is screwed, a specific pressure is created on the profile protrusion 111 so that it plastically deforms , and due to this, the geometric closure of the conical head 116 with the protrusion 111 of the profile.

Then, as a result of screwing the lock 118, also due to rotation by means of a rotary tool (not shown) between the lock 118 and the first profile protrusion 110, a geometric closure can also be realized, due to which the load-bearing capacity of the device in the direction of the groove is further increased.

The dismantling of the device 100 can also be carried out simply, for which the above steps should accordingly be carried out in the reverse order.

In the following examples of the implementation of the device according to the invention, in order to avoid repetition, we will only talk about the differences compared with the above-described device 100. Therefore, the previous versions, of course, apply to the examples described below. This means that structural elements with similar functions in comparison with the first embodiment are denoted by an ordinal number from the corresponding first embodiment, increased by one hundred.

The difference between the second exemplary embodiment of the device 200 shown in FIGS. 2a-2d essentially lies in the fact that the second part 228 of the clamping element 314 has an edge 239 with a smooth lower side radially protruding outside the conical head 231, so that the clamping forces are over a large area of the clamping plate 225 and the load on the material is reduced.

The following example of the implementation of the device 300 is shown in figa-3d.

In the device 300, the clamping element 314 is made of one part. It has a conical head 316 with an edge 339 radially protruding beyond the conical surface.

A threaded portion 341 with an external thread extends from the conical head 316 and adjoins an extension 342 with an outer surface of cylindrical shape having a smaller diameter than that of the threaded section 341. An edge 343 is provided at the free end of the extension 342, radially protruding beyond it, the diameter of which slightly smaller than the diameter of the threaded hole for the threaded section 341.

At the end end of extension 342, an internal hexagon 344 is selected to engage a rotary tool (not shown).

The clamping element 314 is located in the elongated hole 313, which has an internal thread corresponding to the thread of the threaded section 341 in the segment corresponding to the position of the clamping element 314, in which the second protrusion 337 formed by the conical head 316 enters the second undercut 309.

In addition, as can be seen, for example, from FIG. 3b, a spring element 346 is provided on the front side of the conical head 316.

The installation of this device 300 is first again carried out in the installation order of the device described in accordance with fig. 1b, which is indicated in order to avoid repetition. In this case, the clamping element 314 is in a position in which the extension 342 is located on the portion of the elongated hole 313 without thread.

Then, using a tool not shown in the drawing, engaged with the internal hexagon 344, the clamping element is moved to the position shown in FIG. 3c, in which the threaded section 341 is in the continuation of the internal thread 345. At the same time, the spring element 346 resting on the plate the base 306 of the groove 304, presses the edge located between the threaded section 341 and the extension 342 against the edge of the internal thread 345 facing it.

If in this position, the clamping element 314 is rotated in the direction of screwing into the internal thread 345 using the appropriate rotary tool, then it moves to the position shown in fig.3d, in which the device is installed on the profile, described in detail with the example of the device 100.

A fourth embodiment of the device 400 according to the invention is shown in FIGS. 4a-4b.

In this device, the functional elements - here the hinge elements 421, 422 - are made in one piece with the end sections 403 of the base plate 401. The clamping element 414 in this embodiment has a circular base 447, in which a threaded hole 448 is selected in the center. The diameter of the base 447 is selected so that it fits between the protrusions 410, 411 of the profile. On the section facing the base 406 of the profile 405, on the basis of 447 at an angle of 180 ° to each other, in other words, against each other, radially protruding extensions 449, 450 are formed, forming the first and second protrusions 433, 434. The dimensions of the extensions 449, 450 are designed so that after turning the clamping element 414 through 90 °, they fall into the undercuts 408, 409.

The clamping forces in this exemplary embodiment are created by the clamping screw 451 screwed into the threaded hole 448. The head 452 of the clamping screw 451 is conical. It, with its conical surface 453, rests on the counter surface 454 of the central hole 455 of the circular clamping disk 456.

The device is mounted so that it is first installed on the profile 405 in the manner described above, with the clamping element 414 being oriented so that both extensions 449, 450 are facing the groove 405 of the profile. This position of the clamping member 414 is shown in FIG. 4b.

After that, the clamping element 414 rotates through an angle of 90 ° so that the extensions 449, 450 go into the undercuts 408, 409. In this position, shown in Fig. 4c, the clamping screw 451 is tightened until the position shown in fig.4d, in which the protrusions 449, 450 extend beyond the protrusions 410, 411 of the profile.

5a-5e show a fifth embodiment of an apparatus 500 according to the invention.

Instead of elongated holes, such as that of the device 100, in this embodiment, round holes 513 are used to install the clamping elements 514 in the base plate 501.

The clamping elements 514 are again made in two parts. The first part, located in the hole 513, has a section 557 symmetrical with respect to the axis of rotation, the outer diameter of which is slightly smaller than the internal diameter of the holes 513, so that the clamping element 514 can freely rotate around its longitudinal middle axis. At the end facing the base 506 of the groove 504, an extension 550 is provided at the clamping member 514, radially protruding about a quarter of the circumference and forming a second protrusion 534. In addition, a threaded hole 530 is provided in this part of the clamping element 514, at the lower closed end of which internal hexagon 544.

A clamping screw 551 is screwed into the threaded hole 530, the lower side of the head 552 of which rests on the upper side of the clamping plate 525. The hole 558 in the clamping plate 525, through which the clamping screw 551 passes, is elongated with two sides parallel to each other. The clamping element 514 at its end facing the clamping plate 525 has two turnkey faces 559 corresponding to two parallel sides of the hole 558, which are oriented so that when the second protrusion 534 of the clamping element 514 is turned away from the second undercut 509 or comes in into it, they are engaged with the edges of the hole 558.

The installation of the device 500 occurs in the manner described above, when the clamping element 514 is rotated to the position shown in FIG. 5b, in which the extension 550 is turned away from the second undercut 509. The clamping element 514 in this position is pressed against the clamping plate 525 using a spring element 546, resting on the base plate 506 of the groove 504, so that the key faces 559 are engaged with the parallel edges of the hole 558.

As a result of the engagement of the rotary tool (not shown) with the internal hexagon 534, the clamping element 514, as shown in FIG. 5c, is pressed down against the elastic force of the spring element 546 so that the key faces 559 disengage from the edges of the hole 558. After that the clamping member 514 can be rotated 180 ° to the position shown in FIG. 5d, in which the extension 550 engages in a second undercut 509. In this position, the clamping process itself may consist in tightening the clamping screw 561. When this extension 550 is shifted up. The bevel provided at its end portion acts in such a way that the first protrusion 533 moves into the first undercut 508 and due to the plastic deformation of the profile extensions, a geometric closure occurs.

Another example of the implementation of the profile 600 according to the invention is shown in figa-6d.

With this embodiment of the device 600, a second protrusion 634 is formed due to the edge portion 660 of the plate clamping element 614. When viewed from above, it is approximately T-shaped, with the part of the clamping element 614 corresponding to the vertical line “T” passing between the two generatrices the first protrusions 633 of the latches 618, which in their shape and design correspond to the latches 118 in the form of execution of the device 100.

The plate clamping element 614, on the side facing the end portion 603 of the base plate 601, has bulges 661 resulting from plastic deformation of the plate clamping element 614 under the action of a pressing tool with the opposite side of the clamping element 614 in accordance with FIG. 6a. Varying the height of the bulges the clamping element 614 can adapt to various thicknesses of the protrusions 610, 611 of the profile. To this end, the bulges preferably have a height approximately corresponding to the thickness of the profile protrusions 610, 611 so as to avoid skewing in a direction that is not parallel to the base plate 601, leading to the edge portion 660 forming the second protrusion 634, in the process the clamp slides out of the second undercut 609.

The clamping forces are created by two clamping screws 651 passing through the holes 627 in the clamping plate 625 and the holes 624 in the hinge elements 621, 622 and screwed into the threaded holes 662 in the clamping element 614.

The fixing process is described based on fig.6b-6d. To do this, the device is installed on the profile 605 as described above. At the same time, the clamping element 614 is in a position in which the edge section 660 releases the second undercut 609. For the edge section 660 to enter the second undercut 609, a control pin 663 is provided in the clamping element 614 through an elongated hole in the hinge element 621, 622.

If, using this control pin 663, the clamping element 614 is moved to the position shown in FIG. 6 as a section of the threaded hole 662, the clamping process can be carried out by screwing the clamping screws 651 into the threaded holes 662. In this position, the holes 624 and 627 are several offset relative to the threaded holes 662 perpendicular to the longitudinal direction of the profile so that the tightening of the clamping screws 651 leads to the occurrence of a component of the force that moves the edge portion 660 of the clamping element 614 in the second an undercut 609, and the hinge elements 621, 622 in the opposite direction, respectively. The result is a particularly reliable engagement of the protrusions with the corresponding undercuts.

In the exemplary embodiment of the loop 700 shown in FIGS. 7a-7e, the clamping elements 714, unlike the above-described embodiments, the descriptions of which, however, will have to be referred to again, are not installed together with other components of the device 700, but being made in the form of screws 716 with a conical head with a threaded rod 715, from the front side of which an internal hexagon 744 has been developed for coupling with a rotary tool, they are inserted into the groove 704 when the second protrusions 734 enter the second undercuts 709.

To fix the clamping elements 714 for subsequent installation of the components of the execution form of the device 700 (hinges), these clamping elements 714 are connected using the auxiliary installation tool 763, clamped into the groove 704.

Fig. 7a shows four embodiments of this auxiliary installation tool 763. Embodiments I, II, and III include mounting elements made of strip steel, at least partially covering conical head screws 716 at the transition from the head to the threaded rod and in one of both undercuts 708, 709. Embodiment IV of an auxiliary installation tool 763, which is particularly easy to manufacture, includes a spring steel wire mounting element that is wound with effort on the screws with a conical head 716 again at the transition from the head to the threaded rod and has portions which come in first or undercut 708 or the second undercut 709 of the groove 704.

After the clamping elements 714 are installed in the groove 704 using auxiliary mounting means 763, the base plate 701 with pre-mounted clips 718, the shape of which matches the shape of the clamping elements 714, is mounted on the profile 705 and moved so that the first protrusions 733 formed by the clips 718, hit the first undercut of 708.

Openings 764 are provided in the hinge elements 721, 722 for mounting the second part 728 of the clamping element 714. The holes 764 have a round shape, which on one side has a flattening to form a turnkey face.

The second parts 728 are respectively cylindrical in shape with a mating face 765 turnkey. Thus, they are securely fastened in the holes 764. For the reception of clamping forces, the second parts 728 have a radially protruding edge 766, mounted on the upper side of the hinge elements 721, 722.

The holes 764 are arranged so that the threaded rods 715 of the clamping elements 714 after being installed on the profile of the base plate 701 and the hinge elements 721, 722 are aligned with the threaded holes 768 provided in the second parts 728, as shown in FIG. 7c. After the second parts 728 have entered the holes 764 (see Fig. 7d), the clamping element 714 can be rotated until it is in the clamped position, as shown in Fig. 7e.

Another particularly preferred embodiment of the device 800 is shown in FIGS. 8a-8e. In this case, the embodiment of the base plate 801 corresponds to the embodiment of the base plate 701 from the exemplary embodiment of the device 700. However, in contrast to the exemplary embodiment of the device 700, the holes 864 are made so that their diameter decreases in accordance with Fig. 8a downward, i.e. in the direction of the base plate 801. The second parts 828 of the clamping elements 814 respectively have an outer surface 867 tapering downward so that they rest with their circumference on the inner circumference 869 of the holes 864. In addition, a turnkey face 865 is provided on the outer circumference of the second parts 828, which is in the installation position on the profile 805 interacts with its protrusion 811 and thereby provides protection against rotation.

Installation for the case of this embodiment of the device will be described based on fig.8b-e. First, the hinge elements 821, 822 pre-mounted with the base plate 801 and the clips 818 are set to the position shown in FIG. 8b. Then, the pre-assembled clamping element 814 at a slight angle, as shown in Fig. 8b, is inserted through the hole 864 into the groove 804, as shown in Fig. 8c. Upon reaching the position shown in FIG. 8d, the conical head screw 816 is tightened until the clamping position shown in FIG. 8e is reached. Moreover, the turnkey face 865, resting on a smooth profile surface, helps to ensure that the second part 828 of the clamping element 814 is not involved in the rotation.

As can be seen from the above description, due to the embodiment of the device 800 according to the invention, it can be mounted on the profile particularly simply. In addition, this form of execution is characterized by the presence of a particularly small number of mounting elements, as well as the fact that no mounting elements extend beyond the outer surface 866 of the mount, and therefore this device does not take up much space. Therefore, the distances between adjacent profiles can be especially small.
