Description

Scissor limiting device.

The present invention relates to a device scissor type limiter for a swing, swing and swing swivel or swivel and swingarm, which is arranged in a frame fixed, which is constituted at least by a limiting device scissors type, which is mounted, with one of its ends, in a guide piece and, with its other end, in a bearing block of scissors held stationary, rotatably rotating, respectively, the guide piece of being guided so that it can move in the longitudinal direction in a guide groove and presenting a brake device.

Limitation devices of the type of scissors for a rotating swing, swivel-swingarm or tilting-swivel arranged in a fixed frame. They serve to limit the turning area or the area of tilting, that is, in general, for the limitation of rotating movement of the respective blade, most of the time at 90º.

It is known by the document FR-A-2 446 911 a device scissor type limiter of this type, which presents the characteristics of the preamble of claim 1.

It is also known by document DE 44 07 245 another scissor-type limiting device for a rotating swing, swivel-tilt or swivel arranged in a fixed frame.

The scissor-type limiting device features in its support eyelets, which are mounted in each case of rotating shape on an articulated pin of the bearing block of scissors A respective first articulated pin is part of a scissor bearing block on the side of the fixed frame and a second articulated pin is part of the scissor bearing block of the side of the sheet. The position of the scissor stands are adjusted by means of templates and then are tied with the purpose of prior assembly through impact introduction in the frame, penetrating by incision a cutting edge, placed in the lower side of the scissor bearing block, in the frame of the sheet and in the fixed frame, respectively. Then it takes out the anchoring of the scissors supports by means of screws which are screwed into the fixed frame and the leaf frame, respectively.

Known folding scissors are configured of two parts, presenting the two type parts telescopic, respectively, a cam slot, in which slide a retaining pin in each case removably. The Cam slot also has seals, which fit the retention pins during travel through the groove of cams and provide a braking action.

In the folding scissors known, on the one hand, assembly is complicated and laborious and, on the other hand, during Impact introduction of scissor holders in the fixed frame and in the window frame these are easily damaged components. Local damage can lead, conditioned by the climatic influence, to inadvertent erosion of the frame. The erosion may impair, to an unknown extent, the resistance of the screw connection to the point that it can be released from suddenly In addition, security measures must be provided expensive for transportation and in particular a special attention to small parts, since they are lost with facility at the installation site.

Another device is known in the market scissor type limiter under the designation limiting device type WSS tilting scissors from Wilhelm Schlectendahl & Söhne This scissor-type limiting device is mounted so rotating stationary on the side of the fixed frame in a block of frame that can be attached to the profile of the leaf frame, the scissor-type limiting device being fixedly connected with the frame block. On the side of the leaf frame, a guide piece is guided in a guide groove so that it can be moved in the longitudinal direction, the device being attached scissor type limiter, rotatably mounted, with a stand on a rotating pivot that is in the guide piece and being held by a safety plate. The piece of guide presents on the side opposite the pivot pivot, that is, on the rear side, an axially shaped clamping arch and which can be retained by a clamping screw, whose arc of clamping exerts, according to the respective tension, a braking action in the guide groove. A stop, which can be fixed in the groove of guide, limits the travel path of the guide piece and in this way determines the turning area of the sheet of the window.

On the other hand, the present invention relates to a guide piece for a scissor type limiting device, which is arranged in a fixed frame or on a swinging swing, swivel-swingarm or tilting-rotating, which is constituted at least by a scissor-type limiting device that is mounted, respectively, pivotally articulated, in one of the ends, in the guide piece and, at the other end, in a block of scissor bearing, the guide piece being guided in a groove guide so that you can move in the direction longitudinal and has a brake device.

Limitation devices of the type of scissors that are mounted, on the one hand, stationary so rotating and, on the other hand, rotating in a guide piece, and this one it can be arranged again in a guide groove so that it is removable mounted in the longitudinal direction. Is also known associate the so-called brakes to the guide piece, which avoid a too rapid movement of the guide piece through the guide slot and, therefore, an outward turn of the sheet of the Window or door leaf. However, it is problematic is adjustment of the components and especially of the limiting device type scissors proper, as follows from DE 44 07 245, which provides for this purpose a device special.

It is known from EP 0 538 586 other scissor type limiting device, which is mounted so removable and adjustable on a base plate that is mounted on the side of the frame, so that the window leaf can be corrected to an insignificant extent in the state assembled according to the requirements

The plurality of the components involved requires, as already mentioned at the beginning, an expense correspondingly high in storage and assembly. Too manufacturing is expensive and therefore the storage of Reserve components is correspondingly broad. The Resource involvement is high to a disproportionate extent, of according to the value of the components.

Security must also be taken into account against the irruption. Limiting devices of the type of Known scissors only have the ability to resist sometimes with limitations an attempt of irruption, since due to reduced space ratios, security means are more or less accessible, being difficult to mount rails limitation and, therefore, expensive time.

For fixing the fixed frame on the wall, there are to separate, in general, the fixed frame sheet in place of the installation, or at least suspend the type limiting device scissors to enable correct fitting mounting. This requires considerable work expense during assembly. In addition, it is latent a danger of considerable injury, since during the disassembly and / or assembly of the blades from and in the fixed frame, respectively, severe crushing may occur, especially of the hands or fingers.

A component of a type limiting device scissors for a rotating swing, swivel-swingarm or tilting-swivel, arranged in a fixed frame, It is sometimes made up of a guide piece that has a brake device, which is pivotally mounted at the end of the scissor type limiting device and that is guided in a guide groove removably in the direction longitudinal. At the other end, the type limiting device scissors is received swivel articulated in a block of scissors bearing.

A guide piece of this type is subjected, as a mobile component, to great wear. On the other hand, it is of decisive importance for the correct operation of the scissor-type limiting device. In the known guide piece mentioned at the beginning, the braking action is caused by a
bending section of the bridge type of the bottom of the guide piece that points inward and slides in the guide groove, on the one hand, or by means of the support on surfaces of the guide groove, which are directed towards the scissor type limiting device, on the other hand. The material load is in this case comparatively large. A break of the
Flex section leads to immediate and persistent disturbance of function. The surface of the guide groove, which is directed towards the scissor-like limiting device, in this case exerts a great influence on the guide piece. The notches, the rebates and the like scrape on the guide piece and can drastically impair the braking action.

Therefore, the purpose of the invention is create a scissor-type limiting device, which has an expense reduced components, can be easily transported and You can ride easily as well as it is safe while driving.

This task is solved in a device scissor type limiter according to the characteristics of the patent claim 1. The brake device features the minus a functional medium (expansion wedge) that has a flank wedge, which forms, together with the guide piece, a component integral, joined with the guide piece by material union in a inactive starting position, the functional medium can be separated (expansion wedge) by means of an adjustment member outside the integral union of the material (joining ribs) of the piece of guide through the application of force, and can be transferred to a functional position, in which the wedge flank enters into operational action with at least one ramp surface congruent of the guide piece for the purpose of generating a braking action in the guide groove, which can be adjusted from a viable way with the adjustment member.

In this case, the material bonding can be carried out preferably, so to speak, by means of a film hinge. A guide piece of this type is characterized above all because it can be easily manufactured as a series product by means of the injection molding technique and preferably the
braking action acts on the walls of the guide groove. In this way, the material of the guide piece is largely protected against edges and similar scrapers and the braking action can be kept almost constant for a long period of time. The assembly as such is very simple, since during the previous assembly it is not necessary to insert special brake parts in the groove or in the guide piece, but only the guide piece must be inserted in the guide groove.

Advantageously, through the member of adjustment, by application of a force acting on traction, both the functional environment can be detached (expansion wedge) outside the integral union of the material - especially in the form of film hinge or similar, as you can also adjust the braking action with the adjustment member. In this way, during the assembly, by means of the adjustment member and, on the one hand, is can separate the expansion wedge and at the same time for another part, you can adjust the braking action in a lasting way In a work stage.

Advantageously, the adjustment member is extends essentially in the longitudinal direction, relying on one end and continuously arranging the guide piece, being received at the other end the scissor type limiting device, swivel mounted.

Through the relative alignment of the medium functional guide part can be mounted the guide member of a simple way.

According to another feature, the member of setting is configured in an advantageous manner in the form of a adjusting screw, which penetrates through the guide piece into the longitudinal direction in a cut that penetrates through the piece as guide. In this case, the adjusting screw engages without the outside application with an internal thread of the functional medium (wedge of expansion), the expansion wedge being joined with the piece of integral guide with preference by means of ribs union that are arranged symmetrically to the inner thread providing a positive union of the material. Screw adjustment rests without load application with a collar, with preference with the screw head on the outside of the piece of guide, entering the adjustment screw first with its collar in operative connection with the guide piece when the set screw. If pressed further, the functional medium it is separated from the material junction of the junction ribs and the Functional medium (expansion wedge) finally moves to a position Functional that generates a braking action. The guide piece configured in this way can be mounted in a way especially simple.

According to another feature, it is Especially advantageous for pre-assembly, than the guide piece and the scissor-type limiting device are joined together to Form a handling unit. In this way, the unit of handling can be safely received in the guide slot and It can be secured with a stop. Preferably, the cap presents such end at least one jaw, which affects the limiting device type scissors in the area of the head with mushroom head and fixed of This way the handling unit. This way you can avoid that the scissor-type limiting device be damaged in the event that be transported in an uninsured way, since the framework of the sheet and fixed frame are often transported separately to the installation place.

According to another feature, it is advantageous. that the scissor-type limiting device has joining means, with which it can be joined, by means of a blocking union, with the scissor bearing block in a housing associated with it.

The anchor connection of the limiting device scissors type, out of the inactive position with the block Scissor bearing stationary, allows a Especially fast assembly and safe handling. The period of time, during which the parts are not insured and, therefore Therefore, they represent a danger of injury, it has been limited to a minimum. Immediately after joining, the type limiting device respective scissors is insured. The assembly is not complicated and it It can be done by less experienced people. Finally, for The assembly does not require special devices. The object of the invention solves in a surprisingly simple way several related tasks. In particular, in addition to manufacturing and of favorable cost storage, the security, since the anchor union is barely accessible from the outside.

In an advantageous manner, the joining means is formed by a busty mushroom head, which is fixedly attached at one end with the scissor type limiting device, presenting at its other end a stop chamfer and presenting in the area of the stop chamfer a recess, being able to be fixed axially the mushroom-head busty in the housing with the effect of retention in the recess and can be rotatably mounted in the accommodation. In this way a manufacturing is achieved Especially simple with high functional safety.

According to another feature, it is advantageous. that at least one spring element is associated with the housing, which provides the anchor joint in an automatic way, with what that the scissor-type limiting device can be adapted in one simple way to the needs of different sizes of construction and weights and no devices needed additional and similar during assembly.

According to another feature, the element spring is rotatably mounted at one of its ends and is tied with respect to the degree of axial freedom and is mounted tied at its other end with respect to two degrees of freedom, the housing for the mushroom-head stud being arranged approximately in the center of the spring element. This facilitates the assembly to a considerable extent, getting at the same time a safe union of the mushroom-head busty and accommodation.

According to another feature, the element spring has at its rotating end at least one organ of fit, preferably in the form of an inner hexagon. This In this way, assembly and disassembly is also facilitated, since can be released automatically with a tool corresponding locking union of the type limiting device scissors and scissors bearing block.

In an advantageous manner, the spring element it has a support pivot, which is provided with a connection by elastic snap, the support pivot being mounted so rotating in a support drill of the scissor bearing block and the joint being fixed by elastic fit in an axial direction, which further simplifies manufacturing as well as mounting.

In a preferred manner, the spring element It has at least one half spacer, which is supported, when the introduction of mooring of the joining means, against a wall of the groove. This guarantees without additional means that, during the next connection of the mushroom-head busty with the scissor bearing block, the union of blocking.

According to another feature, the element spring is received in the slot in the inserted state of the scissor bearing block so that it is not accessible from the exterior, which makes manipulations difficult.

Advantageously, the spring element especially presents a section in the housing area rectangular transverse. This way you get a good use of the material as regards the technique spring Optionally, the spring element presents also in the housing area, parallel to the pivot of support, at least one hollow curved rounding, which reinforces the joint mooring through the extension of the active surface.

Essentially, according to another characteristic, the scissor bearing block has a shape extended and can be fixed with a retention member, with preference in the groove of the fixed frame by means of a member of subjection.

Advantageously, the bearing block of scissors has a symmetrical shape, the means of center retention. In this way, it is additionally downloaded to reserve storage, since the bearing block of scissors is suitable for both left-hand but also for right stop.

The retention member also presents means for biaxial fixing of the spring element, which can be configure in a special way in the form of protrusions with ease in the retention member.

According to another feature, the element spring is aligned in the longitudinal direction of the block of scissors bearing, resulting in the advantage that the property of spring can not only influence the material, but also of according to the length that can be chosen in this case freely. It follows an improved elastic property.

It is especially advantageous that the element of spring is in the direction of the device load scissor type limiter and that the mushroom head busty be received in positive connection in the scissors bearing block. From this way a lasting additional retention of the pressure-driven scissor-type limiting device, in the blocking union, the pressure can be distributed on a greater attack surface and thus reducing tension by pressure

From the point of view of the technique of manufacturing, according to the invention, a product is advantageous semi-finished for a guide piece, which is conducted so removable in the longitudinal direction in a guide groove of a fixed frame or swivel swing, swivel-swingarm or tilting-swivel, for joining with a scissor-type limiting device, which is mounted, in one of the ends in the guide piece and at the other end in a block of scissor bearing, in each case swivel articulated, presenting the semi-finished product for the guide piece a medium functional for a brake device, when the functional means of brake device is associated, by means of at least one binding rib, to the guide piece in an integral joint of the material, presenting the binding rib at least one point theoretical breakage for the purpose of subsequent separation and the transfer of the functional medium to a functional position that generates a braking action. A semi-finished product of this type allows a considerable reduction of the manufacturing process, especially when manufactured as a serial part cast by injection.

Preferably, it consists of a polymer, with which you can easily mix additives that they can influence in a simple way the properties of the desired shape

Advantageously, the semi-finished product for the guide piece has a symmetrical shape with respect to the axis longitudinal. In an advantageous manner, in this case, the medium Functional is configured, according to another feature, essentially as an expansion wedge with at least one wedge flank and with an internal thread that is oriented in the direction longitudinal. The semi-finished product for the guide piece presents a drill largely aligned with the inner thread and that crosses the semi-finished product for the guide piece in the longitudinal direction The semi-finished product for the piece of guide itself has at least one ramp surface specially arranged inside and that is congruent with the wedge flank.

The configuration of the guide piece allows the use of guide grooves with reduced construction height as well as the use of the so-called Euro-slots (10 to 14 mm) and with this the component expense is reduced.

In particular, the application of the force of articulated scissors on the brake is essentially maintained constant, so that a braking action can be achieved uniform over a long period of time.

The invention is explained below with the help of an exemplary embodiment represented more or less schematic The same components have been designated in each case with the same reference numbers.

Figure 14 shows a semi-finished product of a guide piece according to the invention.

Figure 1 shows a device 10 of a rotating swing 11 in the turned out state so that it can be opened to the right and to the left, respectively. The rotating blades 11 are joined in each case by means of a hinge support 12 with a fixed frame 13.

A device can be clearly recognized scissor type limiter 14, which is mounted, at one end 15, in a guide piece 16 and, at its other end 17, in a block of scissor bearing 18 in a swivel articulated manner, respectively. The guide piece 16 is guided in a way removable in the longitudinal direction in a guide groove 19. Its movement zone is limited by a stop 21 in the direction of opening 20 of the leaf 11. With the stop 21 the angle of opening-most of the time in 90º-. The bearing block of scissors 18 is fixedly arranged in a slot 22 of the fixed frame 13 stationary in the hinge support area 12.

As clearly deduced in particular from in figure 2, the guide piece 16 moves in the guide slot 19 of sheet 11 towards stop 21 when it opens and moves moving away from the top when it closes.

The scissors bearing block association 18 and of the guide piece 16 may also be made to the inverse, that is, in such a way that the scissor bearing block 18 is associated with the rotating blade 11 and the guide piece 16 is associated with the fixed framework 13.

With reference to figures 3 to 5, a The scissor bearing block 18 which is explained below is explained arranged fixed in slot 22 of the fixed frame 13. The block of scissor bearing 18 has an extended shape, essentially symmetrical and can be fixed with a retaining member 30 arranged in the middle in the groove 22 of the fixed frame 13 by means of a clamping member 31. Clamping member 31 is arranged transversely to the longitudinal axis of the bearing block of scissors 18, inclined with respect to the groove 22 at an angle of inclination α. The side of the clamping member 31, which is directed towards the groove 22, it has a fixing tip 32, which it is followed by a pressure cone 33, whose flank angle β corresponds largely to the angle of inclination α. If the clamping member 31 comes into operation in shape of a set screw, then the fixing tip 32 first deploys a hold action. This has a big advantage for quick assembly, since slot 22 as such is not damaged to an unnecessary extent. Once it has reached the desired position, then, in a second stage, the clamping member 31 enters into full operational action with the slot 22, penetrating the pressure cone 33 into a wall 23 of the slot 22 creating a light cavity 34 and thus creating a semi-positive union, as shown in the figures 5a and 5b.

The retaining member 30 rests in the center in a recess 35 of the scissor bearing block 16, which has, at its distant ends, in each case a stepped support bore 36, in which a support pivot 38 of a spring element 40, which is provided with an elastic snap joint 37. The member of is aligned in the
longitudinal direction of the scissor bearing block 18. In addition, the spring element 40 is mounted at one of its ends rotatably with respect to the scissor bearing block 18 and is fixed by means of the elastic-fit joint 37 in the axial direction in the support hole 36. The spring element 40 is retained at its other end in projections 39, integrally formed in the retaining member 30, as means for biaxial fixing of the spring element 40.

Approximately in the center of the element of spring 40 is arranged a housing 41, which presents essentially a square cross section. The element of spring 40 fits between the projections 39, so that the element spring 40 crosses the housing 41 partially covering it. When the scissor bearing block 18 is inserted in the slot 22, the spring element 40 as such is housed inaccessible from the outside.

Figures 6 to 8 show the collaboration of the scissor-type limiting device 14 and of the bearing block of scissors 18. With the scissor-type limiting device 14 is fixedly attached a busty with mushroom head 45 in one of its ends, which forms a means of connection with the bearing block of scissors 18. The busty with mushroom head 45 features a chamfer of stop 46, which is followed by a recess 47. If the device scissor type limiter 14 must join with the bearing block of scissors 18 after mounting sheet 11 and fixed frame 13 in the wall of the wall, then the mushroom head busty 45 is pressurized into the housing 41, such that the spring element 40 swivels deviates from the stop chamfer 48 in the support hole 36 of the block scissors bearing 18 to finally fit with the effect of retention at recess 47, whereby a axial fixing with a joint 50 mounted at the same time so swivel

The spring element 40 has means spacers 42, which are arranged on both sides of the housing 41, in the form of round pin-shaped appendages which, during the introduction of the mushroom head busty 45 in the housing 41, rest on the inner wall 23 of the slot 22 and avoid a deviation in the axial direction of the spring element 40

The scissor type limiting device 14 is provided, therefore, with a means of attachment, with which one can move, according to needs, from a position inactive, by means of a locking union 50 with the block of scissors bearing 18, to the functional position in the cavity associated with it. To this end, several can also be associated spring members 40, which is in the direction of the load of the scissor-type limiting device 14, which causes the union of lock 50 and secure the scissor-type limiting device 14. In addition, the spring element 40 is provided, in the area of the housing 41, with a hollow arched rounding 43, which is arranged in parallel with the support pivot 38, and which allows fit the spring element 40 deeper into recess 47 and enables a greater mooring load capacity. How it follows from figures 3, 6 and 7, rounding 43 hollow arc is symmetrically arranged in the spring element 40, such which can be used for both the left spring element as well as for the right spring element 40.

On the rotating end, that is, on the pivot of support 38 of the spring element 40, this has an organ of setting arranged in the center, which is configured in the form of a inner hexagon 44 or similar; See figures 3, 6, 7, 9 and 10a. From this way the locking union 50 of the device can be released scissor type limiter 14 and scissor bearing block 18, introducing a corresponding tool 46 and turning the spring element 40 outside of recess 47, whereby release the mushroom head bumper 45 outside housing 41, see Figures 10b and 10c. Through the special configuration of the adjusting member 45 and the corresponding tool 48 can be achieve a high level of resistance against detachment involuntary.

At end 15 of the type limiting device scissors 14, which is placed opposite the bearing block of scissors 18, the guide piece 16 is rotatably mounted -as indicated in figure 1- and is guided in a guide groove 19 so that it can move in the longitudinal direction. The guide piece 18 also has a brake device 60, such as It is shown in figure 1.

The functional state not yet adjusted, is that is, an inactive position 82 of the guide piece 16 is shown in a more exact way in figure 11. The guide piece 16 is shows there with the brake device 60, a part being attached of the brake device 60 in the form of an expansion wedge 61, in the inactive position 62 by material union, by means of two film hinges 63 with guide piece 16. The wedge of expansion 61 features wedge flanks 64 that are arranged symmetrically and an inner thread 65 that is disposed between these flanks. The guide piece 16 is crossed, on the side opposite to the swivel articulated housing of the device scissor type limiter 14, by an adjustment member, which extends essentially in the longitudinal direction, in the form of a screw adjustment 67 with an outer thread 68 in a hole 69 which passes through the guide piece 16, which fits uncharged into the Inner thread 65 of the expansion wedge 61. How can you clearly recognize the adjustment screw from figure 11 67 has a screw head 70, which covers the hole 69, with a collar 75 that can be moved by means of a tool 71 with A corresponding configuration.

Inside the guide piece 16 are arranged spaced ramp surfaces 72, which are configured of shape congruent with wedge surfaces 64 of the wedge of expansion 61, to which members are associated in each case of bridge 76.

If, as indicated in Figure 11, the adjusting screw 67 by means of tool 71, then the screw head 70 with its collar 75 comes first to find a support with the outer side 73 of the guide piece 16. If you continue to screw the adjusting screw 67, then separate the joints from the material, that is, the film hinges 63, which join the expansion wedge 61 with the guide piece 16, in the theoretical breakage points due to resistance exceeded to traction In a next stage, the expansion wedge 61 reaches its functional position 74, in which the flanks of the wedge 64 enter in operative connection with the ramp surfaces 72 of the workpiece guide 16. The desired braking action is then adjusted by of adjusting screw 67. Since the guide piece 16 moves forward with reduced play in guide groove 19, only produced reduced dilations in the area of ramp surfaces 72, that compensate for themselves, on the one hand, due to the elastic properties of the material of the guide piece 16, which is constituted, in general, by a polymer. On the other hand, through of the corresponding configuration of the bridge members 76 is can also exert a comfortable additional influence on the mechanical behavior of the structure of the guide piece 16.

Accordingly, the adjustment member, configured by means of adjusting screw 67, by application of a tensile force separates the material junction integral, which is constituted by film hinges 63, in the theoretical break points 91, and in this way causes also by means of traction the variable adjustment of the action of braking.

As shown in figures 11 and 12, the piece guide 16 and scissor-type limiting device 14 are attached each other to form a handling unit 80.

The handling unit 80 is represented by an expansion wedge 61, which is in the inactive position 62, tool 71 being applied for adjustment. The middle of clamp 67 has not yet been driven hard. Points 91 break theorists are still intact.

Instead, the unit is shown in Figure 12 of manipulation 80 in the active functional position 74 from the point of view of the braking technique. The theoretical break points 91 are separated by virtue of the tensile force that has been generated by the clamping means 67. The wedge flanks 64 of the expansion wedge 61 are in operative union with the surfaces of ramp 72 of the guide piece 16.

As can be deduced from Figure 13, the handling unit 80 can be received in the guide slot 19 of sheet 11, the loose end being secured, provided with the mushroom head bumper 45 with stop 21 as safe for the transport. To this end, the stop 21 has at each end a jaw 82, which surrounds the scissor-type limiting device 14 in the zone of the mushroom head 45 and fix the unit handling 80 or the scissor-type limiting device 14 under the elastic tension of the scissor-type limiting device 14.

The stop 21 has a safety screw 83 for fixing in the guide groove 19. Figure 14 shows a semi-finished product 90, which can be produced preferably at starting from a polymer by means of casting processes by injection, for a guide piece 16 with functional means in the inside, connected in integral union of the material by means of two junction ribs 63, in the form of the expansion wedge 61 for the brake device 60. It can be clearly recognized in the junction ribs 63 the theoretical break points 91 for the posterior separation by means of tensile force. The media functional 61, which are configured by means of the wedge of expansion 61, have two wedge flanks 64, which are associated surfaces inside the guide piece 16 ramp 72 that are configured in a congruent manner.

The guide piece 16, which is arranged essentially symmetrical to the longitudinal axis, it presents in one of its ends a transverse drill 92, which is used for housing rear of the scissor-type limiting device 14 or similar and present at its other end a longitudinal bore 69. A level with the longitudinal bore 69, in the expansion wedge 61, which configures the functional means, an internal thread 65 is arranged, for the subsequent accommodation of the adjustment member 67, with which the expansion wedge can then be separated from the guide piece 16 through the separation of the junction ribs and you can set the desired braking action.
