Description

Belt member

Technical Field

The invention relates to a belt part for fastening and adjusting on a frame or sash profile, comprising: a strap tab having at least one hinge member defining a pivot axis and a strap fastening leg connected to the hinge member; and a belt fastening body which can be fixed in a fastening plane on the frame profile or the sash profile, wherein for fastening the belt tab on the belt fastening body a fastening device is provided which has an abutment face against which the belt fastening leg can be brought into abutment with a corresponding mating abutment face and can be fastened indirectly or directly on the belt fastening body.

Background

Such a belt part or belt fastening is known in a large number of designs, wherein individual adjustment possibilities of the belt tabs relative to the belt fastening body, in particular in the longitudinal and transverse directions, respectively, are possible, so that for example a height orientation and a lateral orientation of the door relative to the door frame can be achieved. The belt fastening body is here essentially a, in particular rigid, component which is firmly connected to the frame or sash profile, against which a belt fastening leg which can be adjusted relative to the belt fastening body rests and is fastened in order to fasten the belt web and ultimately, for example, the door leaf.

A disadvantage of the known systems or devices is that the adjustment of the band lug relative to the band fastening body takes place by means of an adjusting screw which effects the adjustment of the band lug relative to the band fastening body via the lead of the helical thread. The adjusting screw is thus supported both on the belt fastening body and on the belt lug, for example, so that the two components can be moved relative to one another by turning the screw. In this case, however (in particular if a fan or a large fan is already installed), a particularly high expenditure of force is required to turn the adjusting screw. Furthermore, a quick adjustment with a defined distance or a defined adjustment value is not feasible, so that the adjustment is relatively time-consuming and therefore ultimately also relatively costly. Furthermore, in order to be able to adjust the strap tab in more than one direction relative to the strap fastening body, a plurality of adjusting screws need to be provided, whereby an increased space requirement in the area of the strap fastening body or the strap fastening leg is required, which is however in most cases undesirable for visual reasons.

Disclosure of Invention

The object of the present invention is therefore to provide a belt part which improves at least one of the abovementioned disadvantages and in particular enables particularly light adjustment of the belt lug relative to the fastening part, i.e. adjustment of the components which is associated with little effort, particularly fast and requires particularly little and particularly space-saving effort.

The invention achieves the object set by means of a belt part having the features set forth in the independent claim. Advantageous embodiments and further developments of the invention are disclosed in the dependent claims, the description and the drawings.

According to the invention, material recesses which are arranged in each case in correspondence with one another and into which an installation aid for levering or displacing the strap tab relative to the strap fastening body can be inserted are formed in the region of the contact surface and the mating contact surface. In particular, a quick adjustment of the belt lug relative to the belt fastening body, for example at a predetermined distance or a defined adjustment value, can thereby be achieved, so that the adjustment can be carried out particularly quickly and thus particularly cost-effectively. In the adjustment state, the strap web can be mounted movably, in particular movably, relative to the strap fastening body, for example, relative to an abutment surface formed on the strap fastening body, advantageously via at least one bearing, for example, a fastening means guided in an elongated hole. The material recesses are preferably oriented perpendicular to the fastening plane, which is, for example, spanned by the y and z axes, and can be formed (at least at the strap webs), for example, as consecutive holes or recesses. The mounting aid can thus be guided or introduced, for example, from the side of the mating contact surface facing away from the band fastening body through the hole or the recess to the side facing the band fastening body. Furthermore, the installation aid can be introduced further into an additional material recess formed on the contact surface, for example the contact surface of the belt fastening body, and can be supported therein advantageously by means of the free end of the installation aid. For this purpose, the material recess formed on the bearing surface advantageously has a configuration corresponding to the free end of the mounting aid. For example, in the case of the presence of a mounting aid designed as a round bar, the material recess on the contact surface is designed as a blind hole bore corresponding to the round bar, said blind hole bore having a diameter slightly larger than the diameter of the round bar. Alternatively, it goes without saying that other configurations are also possible, in particular corresponding to one another with regard to the cross section and/or the length of the material recess and the installation aid. The lever, which is formed by the mounting aid extending from the material recess of the contact surface through the material recess of the strap tab, enables a manual displacement or displacement of the strap tab relative to the strap fastening body in a particularly simple manner. Furthermore, the belt tab can be moved in a predefined, limited adjustment range, particularly quickly and at a relatively large distance relative to the belt fastening body.

In principle, the contact surface can be provided on the fastening body. In particular, it is preferred that the contact surface is provided on a separately formed adjusting element, which can be fastened to the belt fastening body. The strap receiving tab is thereby preferably movable and/or displaceable relative to the adjusting part and relative to the strap fastening body. In this way, an intermediate adjustment stage can be formed, which enables particularly rapid adjustment and additional, in particular third, adjustment directions at relatively large distances. It can therefore be provided that the strap tab can be displaced and/or offset relative to the adjusting means not only in one plane, but additionally, for example, in a direction perpendicular to this plane, so that the strap tab is adjusted relative to the fastening body, in particular three-dimensionally, i.e. in three directions running orthogonally to one another. The fastening of the strap tab to the adjusting element is preferably carried out by pretensioning a mating contact surface of the strap tab against a contact surface of the adjusting element.

Preferably, the adjusting element is arranged in an at least partially closed chamber formed in the belt fastening body and is mounted in the chamber so as to be movable independently of one another in at least two different directions. This enables a particularly space-saving design of the belt part. In addition, the adjusting element can thereby be supported on the belt fastening body in a particularly simple manner, which is advantageous in particular for the transport and installation of the fastening body and/or the belt lug. Preferably, the adjustment member is movable in the direction of the longitudinal extension of the fastening body, i.e. substantially parallel to the pivot axis. For this purpose, the adjusting means can rest with its two side walls in a planar manner against the side walls of the chamber of the fastening body in a direction perpendicular to the pivot axis and parallel to the fastening plane. A displacement or offset of the adjusting means in a direction substantially parallel to the pivot axis can thereby be achieved and prevented in a direction perpendicular to the pivot axis and parallel to the fastening plane, so that forces, in particular tilting forces or gravitational forces, of the door leaf fastened on the belt web, which occur in a direction perpendicular to the pivot axis and parallel to the fastening plane, can be introduced in a particularly advantageous manner over a relatively large area into the belt fastening body and ultimately into the frame profile or the fan profile. For this purpose, the adjusting element located in the chamber can advantageously be surrounded by six at least partially formed side walls. The strap member is thus also suitable for use at particularly heavy doors or gates. The adjusting element can already be inserted into the fastening body and supported there, for example, at the manufacturer. The adjusting element can be supported on at least one inner wall of the chamber or can be arranged in a clamping manner in the chamber.

Preferably, the adjusting means has an adjusting means section with an abutment surface, which extends from the chamber through a recess formed in the belt fastening body in the direction of the belt fastening leg. In this way, the body of the adjusting means can be arranged in the chamber and only one adjusting means section with the contact surface is arranged on the outside of the band fastening body, so that the band part is particularly space-saving in design.

The chamber preferably has an opening which can be at least partially closed by means of a cover. The adjusting element can thus be inserted into the chamber through the opening in a particularly simple manner, for example, and can be prevented from falling out. For example, the cover can close an opening provided on the side of the fastening body facing the frame profile or the sash profile. The cover may have a side wall, in particular a rear side wall, oriented towards the chamber, on which the adjusting member can be supported. Furthermore, at least one elongated hole-like recess can be formed in this and/or other suitable side walls of the chamber, in which recess the adjusting element is movably mounted, for example by means of a projection, such as a projecting pin, guided in the recess.

Preferably, the contact surface and/or the mating contact surface are provided with grooves or grooves. This ensures a permanent, secure and positionally precise fixing of the tape tab relative to the tape fastener. In particular, the components can be prevented from sliding relative to each other by the increased roughness between the abutment surface and the mating abutment surface.

It is particularly preferred that the grooves or channels are oriented parallel to the pivot axis with respect to their longitudinal extension. Particularly preferably, provision is made for an adjustment of the strap tab relative to the strap fastening body, which can be performed by means of the mounting aid, in a direction perpendicular to the pivot axis. The belt lug can therefore preferably be arranged in a freely selectable position orientation relative to the belt fastening body, which position orientation is predetermined by the arrangement of the grooves, in particular a raised portion formed on the contact surface can be arranged in a recess formed on the mating contact surface. Thereby, a sliding of the belt tab relative to the belt fastening body in a direction perpendicular to the pivot axis can be avoided in particular.

Preferably, the strap fastening leg can be selectively brought into abutment and fastened on the abutment face in a defined position in a direction perpendicular to the pivot axis and parallel to the fastening plane relative to the strap fastening body and/or relative to the adjusting part. The respective position can be preset in particular by forming a groove or a groove. Thereby, slipping, skewing or tilting of the belt receiving piece relative to the belt fastening body can be avoided.

Preferably, at least one elongated hole is formed in the strap fastening leg, through which a fastening means for fastening the strap fastening leg indirectly or directly to the strap fastening body extends. The strap fastening legs or the strap receiving tabs can thereby be advantageously displaced or offset in the direction of the longitudinal extension of the elongated hole (even in the case of the use of fastening means) for adjustment relative to the strap fastening body.

Preferably, a first adjusting screw is provided which is arranged eccentrically with respect to the contact surface and engages with a thread formed on the belt fastening body or on the adjusting element and bears with a free end, in particular with a screw head, on the belt lug such that the pivot axis can be pivoted or offset in a circular movement substantially perpendicular to the fastening plane, in particular in a vertical orientation of the pivot axis in a horizontal direction, in parallel, in particular with a maintained orientation of the pivot axis, when the screw is rotated. In combination with the first adjusting screw, at least one fastening screw is preferably additionally provided, which pretensions the strap receiving piece in a direction of the adjusting part or the fastening body in a parallel plane that is further from the pivot axis than the first adjusting screw. In this way, it is possible in a particularly simple manner to lever or pivot the belt lug, in particular the base hinge part, substantially about the axis of rotation in a direction away from and towards the belt fastening body. In particular, the pivot axis, which is usually oriented substantially vertically, can be offset substantially horizontally, so that, for example, the door at the belt lug has an increasing or decreasing pressing pressure oriented toward the door frame in the region of the side opposite the belt lug. In order to achieve a belt part that is as space-saving as possible, the thread formed on the adjusting part for receiving the first adjusting screw can be arranged in particular on a flange formed on the adjusting part. Preferably, the screw head of the first adjusting screw is supported on the strap mount such that upon rotation of the first adjusting screw, the strap part can be displaced in a direction away from and towards the strap fastening body. It goes without saying that the first adjusting screw can alternatively engage with a thread formed on the strap piece and can bear with a free end or alternatively with a threaded section on the strap fastening body or on the adjusting element.

It is particularly preferred that the strap tab is mounted movably relative to the first adjusting screw in a direction perpendicular to the pivot axis and parallel to the fastening plane. For example, an elongated hole or slot extending in a direction perpendicular to the pivot axis is formed in the strap web, through which elongated hole or slot the first adjusting screw extends or in which elongated hole or slot the first adjusting screw is supported. Thereby, the strap tab (independently of the adjustment of the pivot axis by means of the first adjustment screw) is adjusted relative to the strap fastening body in a direction perpendicular to the pivot axis and parallel to the fastening plane. For this purpose, at least one fastening screw provided for preloading the belt lug on the adjusting part or the fastening body is also guided in the elongated hole or groove by means of a longitudinal extension in a direction perpendicular to the pivot axis.

In particular, it is preferred that the first adjusting screw is mounted with its screw head movably in a groove, in particular a C-shaped groove, formed on the strap. This enables a particularly compact and cost-effective design of the belt part.

Preferably, a second adjusting screw and a third adjusting screw are provided, which are each arranged at mutually opposite ends of the adjusting part, preferably at the same distance from the pivot axis, in particular at the ends extending in the longitudinal direction, and which are each engaged with a thread formed on the adjusting part and each bear with at least one free end against at least one side wall of the chamber, in particular against the inner front side wall and/or rear side wall of the chamber, so that the adjusting part is displaced and/or tilted relative to the band fastening body in a direction perpendicular to the fastening plane when the second adjusting screw and/or the third adjusting screw is rotated. The belt web fixed to the adjusting element can thereby be moved or tilted in a direction perpendicular to the fastening plane, in particular a leaf mounted on the belt web can be horizontally displaced or tilted about a horizontal axis lying in the fastening plane in a particularly simple manner, in particular for setting the height position or for horizontally adjusting the side of the door, in particular the door lock, opposite the belt web. It is particularly preferred that the side wall against which the second and/or third adjusting screw bears is arranged on a cover or profile which closes the chamber. The band element can thereby be constructed particularly compactly. In order to support the second or third adjusting screw and ultimately also the adjusting element, the screws can each be mounted with their screw head displaceably in a groove formed on the belt fastening body. The slot preferably extends in the longitudinal extension of the fastening body, i.e. substantially parallel to the pivot axis. For actuating the second and third adjusting screws arranged in the chambers of the fastening body, the fastening body has a preferably elongated recess, in particular an elongated hole, at least in the region of the respective screw heads of the second and third adjusting screws. Advantageously, the elongated holes are each selected to be so large that a free end of a screwdriver can pass through the holes for actuating the second and third adjusting screws. It is self-evident that the second and/or third adjusting screw alternatively each engage with a thread formed on the fastening body and can rest with a free end on the adjusting element.

Preferably, at least one fourth adjusting screw and optionally a fifth adjusting screw are provided, which engage in each case with a threaded sleeve formed on the fastening body and can bear with their free ends against the fastening leg and/or the adjusting element, respectively, so that upon rotation of the fourth adjusting screw and/or the fifth adjusting screw the fastening leg and/or the adjusting element can be moved along the pivot axis. In this way, for example, it is possible to displace the adjusting element, which is mounted movably by a side wall of the chamber of the fastening body in a direction substantially parallel to the pivot axis, in a particularly simple manner in this direction. Particularly preferably, the fourth adjusting screw, which is arranged substantially vertically in the mounted state of the strap web, rests with its upper end on the adjusting element. The adjusting element, which is pressed against the fourth adjusting screw by gravity, is thereby displaced in height in a particularly simple manner. The fifth adjusting screw preferably rests with its lower end against the adjusting element in the mounted state, so that the adjusting element can be mounted with pretension or without play between the fourth and fifth adjusting screws.

Preferably, a separate fastening screw is additionally provided for at least temporarily fixing the adjusting element on the fastening body. The fastening screw makes it possible in particular to fix the adjusting element during transport and before and during the installation of the strap fastening body on the sash profile or the frame profile. In addition, the compensation of play of the adjusting element in the belt fastening body during operation of the belt web is achieved in a particularly cost-effective manner by means of the fastening screw.

Detailed Description

Fig. 1 shows a design of a belt part 100 according to the invention for fastening and adjusting on a frame or sash profile 5. For example, the frame profile 5 is formed on a not shown door frame, on which the not shown leaf is pivotably supported by means of the strap 1. For this purpose, the fastening body 2 is fastened in a manner known per se to the profile 5 in a non-movable manner in a fastening plane E which is spanned by the y-axis and the z-axis, in particular in a recess or open groove 51. The strap 1 is fastened to the fastening body 2 via the fastening means 20, wherein the strap 1 for adjusting the door leaf relative to the strap fastening body 2 can advantageously be adjusted in three directions.

The belt tab 1 has at least one hinge part 10 defining a pivot axis S and a belt fastening leg 11 connected thereto. The pivot axis S is oriented substantially in the vertical direction in the mounted state of the belt tab, currently parallel to the y-axis. In the present case, the strap fastening leg 11 has a flat-shaped structure which extends in the direction away from the hinge part 10 and is provided with a plurality of individual segments which are connected by arches and are arranged at an angle to one another, wherein the individual segments can each be used to form an additional contact surface of the strap web 1 on the profile 5. Furthermore, the strap fastening leg 11 comprises a plurality of holes or recesses, for example, elongated hole-like recesses 12a and 12b, through which fastening means, for

example fastening screws

77a, 77b, respectively, extend in order to fasten the strap tab 1 on the strap fastening body 2, so that the strap tab 1 can be fixed on the strap fastening body 2 and thus ultimately also on the profile 5.

The belt fastening body 2 is in the present case designed as a support structure with a cavity 21, which has a shape corresponding to the recess 51 of the profile 5 at least on two opposite sides, in particular on the longitudinal side. The band fastening body 2 can thereby be inserted into the recess 51 and fastened in a known manner to the profile 5, for example by means of a rear engagement of the profile wall arranged adjacent to the recess 51. The band fastening body 2 rests on the profile 5 in the fastening plane E, wherein the band fastening legs 11 can also be fastened to the band fastening body 2 in the end parallel to the fastening plane E. For this purpose, an abutment surface 60 is provided in or substantially parallel to the fastening plane E, on which abutment surface 60 the strap fastening leg 11 can be placed by means of a corresponding mating abutment surface 16 and can be fastened indirectly or directly to the strap fastening body 2. In the present case, the contact surface 60 is formed on an adjusting part 3, which is fastened to the belt fastening body 2.

The adjusting means 3 is currently designed as a separate, relatively strong, elongate component which is arranged in the installed state in the chamber 21 of the strap fastening body 2. The adjusting element 3 is preferably inserted into the chamber 21 through an opening or recess 26 on the side of the fastening body 2 facing the profile 5 in the mounted state, in particular on the rear side wall, by the manufacturer. For this purpose, first of all, the second adjusting screw 72 and the third adjusting screw 73 are each oriented with their threaded free end 721, 731 in the direction of the adjusting part 3 and are each inserted with their screw head 722, 732 into a

groove

28a, 28b formed on the band fastening body 2 (for example in a direction parallel to the pivot axis S), in particular in a C-shape. Subsequently, the adjusting part 3 is inserted into the chamber 21 while the free ends 721, 731 of the adjusting screws 72, 73 and the threaded holes 33a, 33b provided on the adjusting part 3 in the

end regions

32a, 32b, respectively, are mutually engaged and partially screwed. Subsequently, the recess 26 of the chamber 21 is also preferably closed by the cover 22 on the part of the manufacturer by means of the fastening screws 78a and 78b, so that the adjusting part 3 does not fall out of the chamber 21 (for example during subsequent transport).

The adjusting means 3 can thus be mounted in the chamber 21 so as to be movable independently of one another in at least two different directions, in particular in the x direction and in the y direction. In the z direction, the adjusting element 3 is mounted in the chamber 21 so as to be immovable, in particular by placing the two

longitudinal sides

35a, 35b of the adjusting element 3 against the

opposite side surfaces

27a, 27b of the band fastening body 2, respectively, or by engaging projections, not shown here, of the adjusting element 3 in

recesses

22a, 22b, which are formed in the form of elongated holes in the cover 22, in particular in the side walls 22 c. For example, for transporting the belt part 1, the adjusting tab 3 can be additionally fixed at least temporarily in the chamber 21 relative to the belt fastening body 2, for example by means of a fastening screw 76.

The adjusting means 3 has, on the side facing the strap fastening leg 11, an adjusting means section 30 which extends from the chamber 21 through the recess 23 formed in the strap fastening body 2 in the direction of the strap fastening leg 11 and on which the contact surface 60 is formed. The projection 36 formed on the adjusting element 3 likewise extends through the recess 23. Grooves or grooves which extend in the longitudinal extension of the adjusting element 3 or are oriented parallel to the pivot axis S are formed on the contact surface 60. The strap-fastening leg 11 can be placed on this abutment surface 60 by means of a corresponding mating abutment surface 16, in particular also correspondingly a groove or a groove formed on the mating abutment surface 16 can engage in each case a raised portion formed in a recess in the abutment surface 60. This reduces the possibility of the tape tab 1 sliding relative to the tape fastening body 2 in a direction perpendicular to the pivot axis S and parallel to the plane E, currently in the z-direction.

In order to fasten the strap web 1 to the strap fastening body 2 or to the adjusting part 3 located in the fastening body 2, which is preferably also done on the part of the manufacturer, the first adjusting screw 71 is first inserted with its screw head 711 (for example in a direction perpendicular to the pivot axis S and parallel to the fastening plane E, currently in the z direction), in particular in a C-shaped manner, into the groove 13 on the strap fastening leg 11. The first adjusting screw 71 and the groove 13 are arranged in particular adjacent to or eccentrically to the contact surface 60. The elongated hole-like recess 14 additionally formed in the region of the screw head 711 is used to provide the possibility of actuating the screw 71, which can be arranged in different positions in the z direction. Subsequently, the belt lug 1 is moved in the direction of the adjusting part 3 while the first adjusting screw 71 is brought into engagement with the threaded hole 31 provided on the adjusting part 3 until the mating abutment surface 16 of the belt lug 1 abuts against the abutment surface 60 of the adjusting part 3. The strap fastening leg 11 is then fastened to the adjusting part 3 by means of the

fastening screws

77a, 77b arranged in the region of the contact surfaces 16, 60, with the grooves or grooves formed on the two

contact surfaces

16, 60 engaging. Subsequently, the fourth adjusting screw 74 and the fifth adjusting screw 75 are screwed into the

thread sleeves

24 and 25 provided for this purpose. This enables the pre-assembly of the belt member 100 at the manufacturer's side to be ended.

After mounting the strip 100 on the profile 5, it can be adjusted according to the following example:

when adjusting a leaf, which is mounted, for example, rotatably on the strap web 1, relative to a door frame with the profile 5, the leaf can be adjusted in the z-direction, in particular for adjusting the door pressing pressure, in a particularly simple manner by means of the mounting aid 4 for levering or moving the strap web 1 relative to the strap fastening body 2. For this purpose, the mounting aid 4, for example a screwdriver or a rod, can be guided in the first position 101 through the material recess 17 formed on the mating contact surface 16 into the corresponding material recess formed on the contact surface 60. The installation aid 4 is oriented here substantially perpendicularly to the fastening plane E and rests with its free end on the base of the material gap 61, as is shown in fig. 2 a.

In principle, the installation aid 4 can have a first rod-shaped section 40 and a second section 41 in the form of a handle. The cross section of the first portion 40 can be designed as desired, in particular the first portion 40 is designed to correspond to the material recesses 17 and 61.

After the

fastening screws

77a, 77b and/or the first adjusting screw 71 have been partially loosened and thus the grooves or grooves formed on the contact surfaces 16 and 60 have been disengaged from one another, the belt lug 1 can be moved relative to the belt fastening body 2 in a direction perpendicular to the pivot axis S, currently in the z direction, with a particularly force-reducing effect by means of the mounting aid 4. For this purpose, the installation aid 4 located in the material recesses 17 and 61 can be pivoted relative to a direction perpendicular to the fastening plane E, in particular in the z direction, such that the installation aid 4 comes into contact with the side faces of the material recesses 17 and 61. As the mounting aid 4 continues to pivot, the strap tab 1 is displaced by leverage relative to the strap fastening body 2 in a direction perpendicular to the pivot axis S, for example into a position 102 in a direction towards the hinge part 10, as shown in fig. 2b, or into a position 103 in a direction away from the hinge part 10, as shown in fig. 2 c. Here, the screw head 711 of the first adjusting screw 71 slides in the receiving groove 13, and the shafts of the

fastening screws

77a, 77b slide in the direction perpendicular to the pivot axis S in the recesses 12a or 12b, respectively, which are configured as elongated holes. When the

fastening screws

77a, 77b and/or the first adjusting screw 71 are subsequently tightened, the grooves or grooves formed on the abutment surface 60 and the mating abutment surface 16 again engage with one another in order to promote the locking of the strap tab 1 on the strap fastening body 3. The strap fastening leg 11 can thereby be fastened in a selectable manner in a defined,

predefined position

101, 102, 103 on the abutment surface 60 in a direction perpendicular to the pivot axis S and parallel to the fastening plane E relative to the strap fastening body 2.

For adjusting the strap 1 in the x direction, in particular for horizontally offsetting and/or tilting the leaf relative to the door frame, a second adjusting screw 72 and a third adjusting screw 73 are provided. The second adjusting screw 72 and the third adjusting screw 73 are engaged by their threads 721, 731 with the adjusting element 3 via the mating threads 33a, 33b and by their screw heads 722, 732 with the strap fastening body 2 via the

grooves

28a, 28b, respectively. When the second and third adjusting screws 72, 73 are turned in the same direction, the adjusting part 3 together with the strap 1 arranged thereon is displaced essentially in a direction perpendicular to the fastening plane E. When the second and third adjusting screws 72, 73 are turned in the opposite direction, the adjusting blade 3 together with the strap connecting piece 1 arranged thereon is tilted relative to the strap fastening body 2.

For adjusting the strap piece 1 in the y direction, in particular for vertically offsetting the fan relative to the door frame, a fourth adjusting screw 74 and a fifth adjusting screw 75 are provided. The fourth and fifth adjusting screws 74, 75 are each engaged by their thread with the band fastening body 2 via a mating thread formed on the

thread bushings

24, 25 and are each placed by their

free end

741, 751 on a projection 36 of the adjusting part 3, which projection projects through the recess 23. When the fourth and fifth adjusting screws 74, 75 are turned in the opposite direction, the adjusting part 3 together with the tape tab 1 arranged thereon is displaced in the chamber 21 in the y-direction in relation to the tape fastener 2 in a direction parallel to the pivot axis S. In order to be able to carry out this displacement, the second adjusting screw 72 and the third adjusting screw 73 are each mounted with their screw heads 722, 732 so as to be displaceable in a

groove

28a and 28b formed on the band-fastening body 2, which grooves are oriented in particular substantially parallel to the pivot axis S.

It should be clear that the scope of protection of the invention is not limited to the described embodiments. In particular, the structure of the strap fastening body, the adjusting piece and the strap piece and the arrangement and orientation of the adjusting screw (without changing the core concept of the invention) can be improved.
