Abstract

Stretching tool (S) is used to stretch an edge section (3') of the carpet (3), which is looped fully on the underside, between first and second hook members (G) adhesively bonded to the floor (2). The edge section projects (X direction) over the second hook member and is fastened by means of a third hook member.A claim is also made for a stretching tool having a ribbed undersurface.

Description

The invention relates to a method for laying one to be attached to the floor with a Velcro fastener Carpet, the carpet underside all over is loop-like and the counter-closure element of the Velcro fastener glued to the floor being, further tensioning of the carpet is carried out by means of a clamping tool.

Methods of this type are known, as are clamping tools, that act as tension clamps or push clamps. It is in this regard on the following publications referenced: EP 0710461 A1, WO 9000877 A1, US 3980274, US 3963216 and US 512 305. Disadvantages of these laying methods are the formation of more accessible, more strip-like Bearing points for pulling clamping (see US 3,980,274).

Laying systems using surface closures how Velcro elements are also known. It is referred to GB-PS 1 187 103. Come here Velcro strips for use while a full-surface Laying is known from GB-PS 1 546 901.

The object of the invention is a carpet laying process to tackle the special grip bars as Makes bearing points unnecessary and still satisfactory provides high tensile stress.

This task is initially and essentially through solved the method features mentioned in claim 1, it is intended that the tension between a first and a second counter-closure element is performed, with an edge portion of the Carpet in the tensioned position via the second counter-locking element protrudes and that, then an attachment the edge section by means of a third counter-closure element he follows. An initial fixation of the carpet in the sense of a basic anchorage close to the wall connects the main laying area, as it were is temporarily fixed on the second counter-locking element, all under effective tension. Only then will the gripping end of the carpet, i.e. that of the initial fixation opposite edge section on the third counter-closure element supported. This last step happens not under the basic tension of the Carpet. It almost forms a relaxation reserve. It has a voltage-comparative effect.

The invention further relates to a method for Lay one on the floor using Velcro fastening carpet, the carpet underside is fully loop-shaped and that Counter-closure element of the Velcro as a strip-like Hook tape is glued to the floor, whereby further tensioning the carpet using a Clamping tool is made, the clamping tool on the foot side on the hook band and on the other is supported on a carpet top, whereby is based on the fact that the support on the hook hand by means of a loop-like foot underside of the clamping tool This results in a operational docking practically on the laying level of the carpet. Correspondingly loop-like base material forms the base material of the second back anyway, is therefore available as an industry-specific starting product Available. The direction of pull is in the shear plane; brings a lot of resistance. An equally stable one carpet-side docking area is obtained by that the support on the top of the carpet by means a claw-like foot underside. A special one Favorable laying flexibility continues in that a pedestal to a perpendicular to the transverse and Longitudinal axis extending vertical axis is rotatable. The clamping tool can therefore be adapted in the corners Align favorably, for example in one miter-like alignment to the floor corner. As position of the stand that is felt to be favorable to installation moreover in the desired rotational position in each case establish. For the subsequent lifting of the as it were clawed support on the hook edge proves it then it turns out to be favorable that a Lever device is provided. That makes it easier Implementation of the process and is also structurally in in no way expensive, since the lever device existing stand can be assigned anyway. Said Lever device has a lever on one side an operating handle and other, beyond a lever joint, has a caulking section. Specifically, the lever sits on a vertical bracket of the pedestal. As the application of the procedure A further relief tool is used Scraper. This can be used for carpeting Scraper device is characterized by two in essentially parallel, vertical aligned, connected by a bracket Squeegees. These can be folded easily "iron out". The strip device is easy to reach designed, this in that the bracket has a handle portion having. The squeegees are also in Length extension different. Less exposed Areas of the carpet can be easily cut over the shorter one Edit squeegee. The aspect ratio of the Squeegee is essentially 2 to 5 to 1. One good doctor-like handling of the stripping device given when a squeegee is essentially in cross section wedge-shaped with the wedge tip pointing downwards is formed, the wedge tip blunt is designed. It can be a convex Act cross-round the wedge tips.

The object is further defined by those mentioned in claim 15 Process features resolved, based on it is that the clamping tool has the same essentially interlocking Training for the counter-closure element for Clamping in surface engagement to the counter-closure element brought. That is how it is Laying system cheapest for tensioning the carpet utilized. There are no exposed areas, for example in the sense of tripping edges. The most minor at all Height projection of the counter-closure element is negligible. As was surprisingly found, the Joining basically identical counter-closure elements very high shear forces. This property will used when bracing. It is also proposed that two counter-locking elements arranged one behind the other in the tensioning direction are provided, the clamping tool in mating engagement with the rearmost counter-closure element is brought and the carpet with both counter-locking elements is arrested. That has the advantage the intermediate fuse and that of tensioning up to the rearmost counter-locking element. Alternatively, you can However, the procedure should also be such that the arrest of the carpet with the rearmost counter-locking element essentially without applying longitudinal tension is carried out. Fixing at the rearmost counter-locking element can therefore be done by hand. About this a certain relaxation reserve is even formed, for example when in different areas a different one with respect to a main clamping force Tension was exerted on the carpet.

A clamping tool for laying a medium Velcro laid carpet, in particular by a method according to one or more of the claims 15 to 17 is advantageously formed by a same surface as an element of the Velcro fastener trained to interlock in the essential exclusive base. Constructively favorable it is that the lower surface of the base is rib-like is trained. The ribs run here the bottom surface of the stand substantially transverse to Clamping direction. Here is the lower surface of the base in a simple way by a Velcro hook element educated. Regarding such Velcro hook elements will apply to the unpublished utility model application 296 06 448. Their Revelation content is fully included here, also for the purpose of characteristics of this document in To include claims of the present application.

Advantageously on a clamping tool according to claim 18 wherein the clamping tool continues to have a sliding foot has to interact with a carpet top, with the base and the sliding foot are movable away from each other, it is that its engagement surface essentially formed like a nail board is.

It also turns out to be a clamping tool advantageous that the needle board has a carpet side Has transverse curvature. This has the advantage that initially only the zenith of such a transverse curvature touches down and is arrested with the carpet. A corrective Repositioning is made easier. Under operation of the clamping tool hugs the nail board because of a flexibility that is also given to him completely on the flat surface of the carpet, whereby then the other nails or hooks in the pile or immerse the like. Then it is still advantageous that the nail board is interchangeable Sliding foot is supported.

A tensioning tool for laying a Velcro fastener laid carpet, especially by application a method according to one or more of the previous claims, is further advantageous trained that the sliding foot sled and via a ratchet mechanism, hand-operated knee lever is driven, which is assigned a pull / push rod, which the Sliding foot under tension of the carpet in the direction of the stand presses. Can be over the knee lever keep the operating forces moderate. In doing so, a powerful pull exercised. To each one in this regard Developing the same resilience brings that Invention in proposal that the pull / push rod mediates a pressure limiter on the sliding foot acts. These can be facilities as they are common with torque wrenches. A particularly simple solution results from the fact that Compressive force limiter consists of a preloaded spring. In order to make the effectiveness evident, there is a proposal in a stroke display on Pressure limiter.

The room 1 shown as the installation site takes on one Bottom 2 an essentially to be braced in the direction x Carpet 3 on.

A serves for the bottom-side attachment of the carpet 3 Surface fastener in the form of a so-called Velcro fastener K.

Components of the Velcro fastener K are a loop element 5 and a hook band 6. The latter acts as Counter-closure element G.

Regarding the loop element 5, it is in Loops 7 of a loop track pointing in the direction of the bottom 2, which the bottom of the carpet 3 as a textile Second spine 8 underpinned. Instead of loops 7 forming knobs can be the textile backing 8 also be formed by a fleece, which according to narrow horizontal stitching behind hook-behind filament sections offers. The bracket of the second back 8 on the underside of the carpet 3 can be an adhesive bond be generated.

Regarding the hook band 6 of the Velcro fastener K it is a multitude of rows arranged Hook 9 as elements of arrest (see figure 6). The hooks 9 go towards their free end in one Hook head 10 over. In said figure only one is relative small, greatly enlarged section of the hook band 6 vividly reproduced.

Between each, in pairs next to each other put hook 9 there is a gap 11. The hook openings Hooks 9 in pairs are directed in opposite directions. The row arrangement, seen in the larger one Hook width area, leads to multi-track structures of the hook band 6, to be referred to as R1, R2, etc. Instead of flat hooks 9, rotationally symmetrical ones can also be used Hooks can be realized, for example in the manner of mushrooms or trumpet-shaped pins, acting as Velcro male parts. The hook depth, measured by the top of the hook head 10 to a film-like Base 12 of the hook band 6 is preferably 0.7 mm to 0.8 mm. The total thickness of the flat Hook element 6 is just under 1 mm.

The underside of the hook band 6 or the base 12 is smooth. It has a self-adhesive layer 13. The Self-adhesive layer 13 allows non-slip fixing of the hook band 6 on the floor 2. In the stocked state is the self-adhesive layer 13 by a protective cover overlay in the form of a film 14. Latter forms the necessary separation layer. On the other hand, can but it is also a separate silicone layer act that would be connected to the protective cover 14. The form of storage of the band-shaped loop element 5 is the wrap.

A is used to tension the carpet 3 to be laid Clamping tool S. This is in the installation direction, i.e. in Direction of the arrow x designed in the form of a bridge. Their span can be adjusted using a hand lever device Change 15, preferably for tightening, reduce. Intermediate is a ratchet mechanism, a rope drum with pull rope and a return spring. Over 15 said reducing takes place. The spring acts in the direction the expansion, after appropriate approval of the Jack lock.

The portal-like clamping tool S also includes one going down from the bridge footbridge facing stand 16. It can be a Act pair of feet. The stand 16 functions as one Fixed point with part 2 of the clamping tool that brings about the floor S.

The other foot is a sliding foot 17. It is also aligned towards the bottom 2 and with the to exciting carpet 3 reversibly connectable. This Movable connection point to the carpet 3 forms an engagement surface 18 in the form of a nail board. Its nails or needles are slanted. It is refer to Figure 9. The bevel at about 60 ° practically forms multi-pulling hooks in the tensioning direction Arrow x deeper into the tread of the carpet 3 Intervene barb-like and thus a safe pull point form.

The sliding foot 17 of the U-shaped profile Clamping tool S can also be paired be. The vertical pillars 16 and 17 are the U-legs and the actual, away from the ground The bridge section is the U-bridge. The U opening faces downward.

The fixation point indicated above between stand 16 and the floor 2 is made using elements of Velcro fastener K reached. This on the bottom side in such a way that there is a transverse to the direction of arrow x Hook tape 6 is attached close to the wall. This happens mediating the self-adhesive layer 13. The hooks 9 are aligned parallel to the wall, upwards pointing.

The clamping tool S is however, essentially interlocking engagement Training for the counter-closure element G for tensioning in the face-side joint engagement to the Counter lock element can be brought. In the illustrated Embodiment is also a Element of the Velcro fastener K on the stand 16. Due the predetermined in the narrow direction of the hook 9 Order of the same and the parallel lateral gap 11, the lower surface of the base 16 is rib-shaped educated. Such ribs are due to the Forming of hook 9 interrupted; the between Row R1, R2 etc. lying open in the clamping direction tooth-gap-like distances are so small that it not to slip or maneuver sideways the hook 9 connected counter-closure elements G is coming. The fleeing is also involved in this Shape of the hook 9, which opposes each other in joining engagement Allow to be assigned in an oblique orientation (see FIG. 7), so overlap.

The ribs or rows of hooks 9 are oriented in the longitudinal direction of the hook band 6, so that the ribs i.e. Hook 9 of the lower surface of the Stand 16 substantially transversely to the clamping direction Arrow x run.

The lower surface of the stand 16 as well as the sliding foot 17 is opposite by a baseboard Cross section of the column sections of the feet 16, 17 clearly broadened. The whole sub area of 16 is hooked and nailed by 17. In the direction of tension Arrow x corresponds to the widening of the double Width of the side of the measured in the same direction Feet 16 or 17. The overhang is the same on both sides.

The carpet 3 is laid as follows: Man begins with the fixation of the aligned carpet 3, also called carpet, on one side of the room 19 of room 1. This is in the drawing on the right. There is a first strip I of the hook band near the wall 6 relocated. After fixing the carpet 3 there Engagement of the hooks 9 in the loops 7 of the second back 8 becomes a second strip II of the hook tape 6 placed at a distance y from the other side 20 of the room. Then a third strip III is laid of the hook band 6, directly at the foot of the room side 20 there, on the far left.

The parallel alignment of all three Strips I to III are explained over the self-adhesive layer 13 secured. Their adhesive force in the shear direction (Direction of arrow x) is larger than the one to be applied Clamping via the stool-shaped clamping tool S.

With reference to Figure 1, that facing the room wall 20 End of the carpet 3 before the second strip II handled, i.e. towards the right-hand side of the room 19 folded. This edge section of the carpet 3 bears the reference symbol 3 '. Then the clamping tool S used. This happens so that the stand 16 on the uncovered, immediately wall - side or rear strip III is placed. Because the ribs respectively hook 9 on the underside of the stand 16 run in the same direction to the hook 9 of the third Strip III, there is a joint intervention between the continuous, parallel to the room wall 20 Hook lines and deep lines, the latter realized through the gaps 11. The given variety of support surfaces in the direction of tension arrow x between the Joining partners leads to an effective plug-in coupling and thus to absorb high blocking forces. Doing so the mutually identical matrix and male parts separate again almost frictionlessly, just as they are can also be added smoothly. This property will fully used by the clamping tool S by this without increased effort by the joining process in the am Floor 2 near the wall of the room side 20 glued rear Strip III can be used and across this through the arrangement of the hook lines / recess lines described above, the horizontally evolving Tension between this acting as a fixation point Connection and the carpet 3 can build.

The second foot, the sliding foot 17, is according to the nail board-like training and described Incline his engagement elements barb-like designed. He (17) can slip and because of the Numerous corresponding nails of the tips slip-free engage in the carpet 3 so that the tension on this can be transferred. The related fixation can again with emphasis after the end of the work To get picked up. The tensioning process is done by contraction exercised via the clamping tool S. Here one can grip mechanical device operated by hand lever, so that the telescoping telescopic portal of the Clamping tool S is moved accordingly. Such Device is for example by the US PS 3,692,278 or U.S. Patent 3,980,274.

After this first tensioning phase, shown in FIG. 1 is achieved by partially laying the folded over The end of the carpet, the edge section 3 ', the carpet 3 on the second strip II speak hook tape 6 non-slip fixed so that after relaxing and removing the Clamping tool S the carpet tension applied between the first strip I and the second strip III essentially remains.

The one released after removing the clamping tool S. third or rear strip III is now free to Recording of the end that can now be completely laid, that is Edge section 3 'of the carpet 3. This end will be without tool-generated clamping force now between the second and third strips II, III fixed. This one too narrow area is non-slip and wave-free because only one between the second and third stripes there is a short distance.

The hook band 6 as a counter-closure element G can, like can be seen from Figure 11, provided with holes L. Corresponding cross sections appear in the holes L. Projections of the base 16 of the clamping tool Be. Holes L and protrusions are in one common raster image. The perforation has also in this respect a meaning when it came to a perfect adhesive bond comes between the hook band 6 and the bottom 2, because air pockets and thus partial neutralization the adhesive effect cannot occur. Draw it there are no dents on the tread of the overstretched Carpet.

A correspondingly linearly arranged rows of holes Hook tape 6 is submitted to the office at the same time has been registered under the internal number 22 567. The content of the full registration is included here, also for the purpose of characteristics of this document in to include the claims of the present application.

The entire clamping process for a complete room 1 is repeated several times, starting from the center of the room repeated on both sides until the carpet 3 or Carpet is held with uniform tension.

An overhang remaining towards the room side 20 is separated in a classic way.

While the distance y as a compensation reserve the main clamping force between I and II can be used, a secondary clamping force between II and III are also omitted if the in FIG shown laying type is used. There is, as described, the base 16 of the clamping tool S positioned and pulling the carpet end forward additionally via a feeder 21 of the clamping tool S. causes. Its foot acts as opposing to 17 acting sliding foot 17 'and is the same Way on the underside as a nail board-like engagement surface realized. Boom 21 and sliding foot or feet 17th are firmly connected, i.e. so also part of the outer, leading telescopic part of the clamping device S. Base 16 and there sliding foot 17 ' can be overlapped together in the direction of arrow x approach or move past. This requires the Kick back of an end corner portion 22 of the Carpet 3. It is an angular one Corner section, at both corners of the carpet section there is folded back. So here it would are sufficient if the rear strip III at a distance y one only according to the width of the corner section 22 cut strips II would be upstream. At A larger carpet width could be a kind in the middle range Bay repelled and in the manner described the tensioning is effected. That would be one continuous, so the same main clamping force for the whole carpet 3 reached.

Of course, the one shown in Figures 1 to 4 is Carpet 3 directly on the floor 2. The layered representation is only due made clearer.

The other means to carry out the procedure using the further developed clamping tool S are explained below with reference to Figures 12 to 19 and with respect to a coating device 23 with reference to Figures 14, 20 and 21. The reference numerals are applied analogously, sometimes without repeated text.

To anticipate the aforementioned stripping device 23: It may be used to wipe away the edge emerging waves when laying carpets. Of course it can also be used later. she has two spatially clearly spaced squeegees 24.25 on. They run parallel to each other and are about one attacking on their respective center Bracket 26 connected to each other like a truss. The free temple ends have a U-shape vertical, down here. They are rooted in the top Back of the upright squeegees 24.25.

At least the central area of the bracket 26 is one Handle section 27 designed. That runs essentially spaced parallel to the space and capable of being gripped under Floor 2.

The squeegees 24, 25 are of different lengths. The shorter ones bear the reference number 24. The aspect ratio the squeegee is essentially 2 to 5 1.

As can be seen from the drawings, the sash strips are 24.25 of wedge-shaped in cross section. Their Wedge tip 24 ', 25' points towards the bottom 2. The back of the wedge is facing the U-legs of the bracket 26. The wedge tip 24 ', 25' directed against the bottom 2 convex cross-rounded. It is so moderately dulled. The bow thrust is therefore free of hooking, like a squeegee from.

With reference to Figure 14 it is clear that the height the stripping device 23 is less than a horizontal one Chassis 28 of the clamping tool S. Since this by its nature also has a bridge shape due to its base lying in the laying direction 16 and the mechanics of the hand lever device 15 retentive sliding foot 17 remains an underpass 29. It can be held down by the acting strips 24, 25 are run through.

Since the bracket 26 and also the handle portion realized on it 27 is quite long, there remains a multiple Gripping width so that the user with his holding hand can start at the position that seems appropriate to him. The stripping device 23 has a double T shape in plan on.

The clamping tool S according to FIG. 12 ff is also supported on the foot side on the hook band 6 on the one hand and on the other hand on the carpet surface. Only is the support now such that the bottom of the base of the stand 16 is formed like a loop. The corresponding Loop strap also bears the reference number 5 here. The bottom of the base of the base 16 is corresponding busy. There is a reversible assignment, so that from time to time a new loop band 5 is assigned can be. The carrier of the same is a cross-section T-shaped clamping bar 30. Your T-bar extends vertically directed upwards. The T-bridge and a him near width section are from a support bar 31st overlap. The latter has a C-profile and is on the top still provided with a stabilizing sheet 32. Both parts 31, 32 are removed from the threaded bolts a clamping screw 33 penetrates the counter thread takes place in the web of the clamping bar 30.

The clamping screws 33 are provided in pairs, so that a balanced, firm clamping of the around the T-leg beaten edges of the loop band 5 between the C-legs and the T-legs of clamping bar 30 and support bar 31 is reached.

The stand 16 or the carrier assigned to it 34 of the loop element 5 is the tensioning tool S. assigned rotatably. The rotary movement is one Vertical axis z-z, i.e. around a perpendicular to the geometric Transverse and longitudinal axes of the base 16 extending Vertical axis.

Stand 16 with support 34 are in a desired Angular position can be determined. A clamping device is used for this 35 in the head area of the pedestal 16.

Part of the clamping device 35 is a toggle handle 36. It starts from the head 37 of a screw 38. Their External thread works with an internal thread of the base 16 together.

Between the screw 38 and the head 37 is a stepped Neck 39 considered. Whose direction Bottom 2 facing end edge 40 acts as a clamping surface with the hole edge of a brake plate 41 of the chassis 28 together. A corresponding counter clamping surface the upward-facing end edge 42 of the at least tubular base in the upper area 16. Turning the toggle handle 36 around the The vertical axes z-z raise the clamping surfaces in the sense of easy ventilation from the brake plate 41 on both sides. The stand 16 can be rotated and then fixing the desired rotational position of the carrier 34 cause.

The sliding foot 17 loads transversely to the laying direction (Arrow x) chassis 28 formed longer. He sits on a carriage 43 on the top. Its sides slide Limit stops in guides 44. They sit on a boom 45 of the chassis 28.

The feeder 45 is the carrier of the hand lever device mentioned 15. This comprises a fixed tooth segment 46. Its toothing 47 is concentric with one horizontally aligned hand lever axis 48. One to the Tooth segment 46 adjoining hand lever is 49 designated. It changes into an end handle 50. The hand mist 49 is hollow throughout.

A ratchet pawl 51 acts with the teeth 47 of the ratchet together. That is in the direction of lock engagement spring loaded. As a spring in this regard serves a leg spring 52. The locking lug of the ratchet pawl 51 is designated by 53. The um a pivot 54, which is also horizontal, on 46 mounted double-arm ratchet pawl 51 can be the end facing away from the locking nose Activate load-bearing ram 55. The latter sits down into an operating button 56. That lies with enough Stroke at the free end of the handle 50 accessible for actuation.

Ratchet pawl 51, plunger 55 and hand lever 49 sit on a swivel bracket 57. This is on the hand lever axis 48 stored and reaches over a pull / push rod 58 on the slide 43. The particular attack is articulated, and realized by a first horizontal Axle pin 59 to the pivot axis 57 and a second horizontal journal 60 for the carriage 43 out. The respective associated bearing eyes are classic style.

Swivel tab 57 and pull / push rod 58 act as one Toggle lever gear.

To form the ready-to-clamp position of the clamping tool S the hand lever 49 becomes the one from FIG. 12 apparent steep slope swiveled. The sled 43 is then found in the starting position. The toggle is brought more in the direction of folding. By triggering the ratchet pawl 51 via the actuating button 56 and Swiveling the hand lever 49 in the direction of the base 16 the toggle lever comes out of its folded position the stretched position shown in Figure 15, in which the carriage 43 is advanced in the laying direction of the carpet becomes. The relaxation happens in reverse Handling. Intermediate positions are due to the ratchet effect the pawl 51 secured. The pulling action on carpet 3 also results from the above engagement surface of the sliding foot shown in detail 17. As shown, it is about this bondage or support on the top of the carpet around a claw-like docking, realized on the bottom of the foot there. The corresponding nail board 61 is arched in the laying direction of the carpet 3. It is a convex curvature towards the carpet 3 is shown. The nails or hooks of equal length with each other follow the corresponding curvature. Through this carpet side Transverse curvature is the engagement surface 18 there Sliding foot 17 nailed at first in the zenith. The correspondingly facilitate a few interlocking elements a repositioning of the clamping tool S. Since that there nail board 61 is also flexible, goes Cross curvature of the same when actuating the clamping tool S or pressing the sliding foot 17 against the Top of the carpet in a substantially parallel Alignment to the top of the carpet above. The fastening device for the nail board 61 corresponds to for the loop band 5 on the support bar 30.

Located in the center of gravity of the clamping tool S. an upstanding, knob-like handle 62. The favors a comfortable implementation of the clamping tool S to the next tensioning point.

But also the removal of the Velcro intervention etc. simplified, this less with regard to the described joining intervention between the hooks 9 of two hook strips 6, that are easy to separate, rather than in terms of the tied up support, resulting from the hook band 6 by means of the loop-like design described Bottom of the foot of the clamping tool S. For this serves a lever device A. The works after Principle of the double lever. The lever device A is located near the stand 16, more precisely this itself. It encompasses one horizontal Axle pivoting lever 63. Its axis is 64 designated. It is located on a vertical bracket 65 of the stand 16. The lever 63 extends parallel to the beam 34, namely on the underpass side lying.

The lever 63 provides an operating handle 66. The sits at the end of a longer operating lever 67, the continues into a shorter lever beyond axis 64, forming a curly stripping section 68. Its corresponding curvature is clearly shown in Figure 17 forth. It is an almost semicircular one Section of curvature, its downward facing Zenith touches the carpet 3. By exercising a force P directed above at the free end of the actuating lever 67, the carrier 34 stands out from the floor 2. The loop work on the underside of the foot of the pedestal 16 is torn off from the hook band 6 there. The curvature of section 68 avoids damage. It comes as a stripping of the stripping section 68.

The process steps are those already explained Process steps for the subject explained above basically identical; it is said to be on more related statements are waived.

The clamping tool shown in Figures 22 to 24 S corresponds in the essential technical details the clamping tool S, which is described in relation to FIGS. 12 ff is. The reference numbers have been adopted, for the most part Part without repeated text. The added consists in the special design of the Pull / push rod 58, which together with the swivel bracket 57 forms a toggle lever 70. This pull / push rod 58 is now implemented as a pressure limiter.

The pressure limiter reacts when it reaches one determined traction exerted on the carpet 3 the sliding foot 17. This leads to a train-related even laying. So different Avoid tension zones or distortions.

Such a pressure force limiter can consist of a piston / cylinder unit exist, containing a biased Feather.

A two-part pull / push rod 58 is shown, comprising a guide cylinder 71. This leads a rod 72. From the end facing the base 16 a stepped extension of the guide cylinder 71 73 out. The forms a terminal bearing eye 74 as Part of the relevant linkage to the slide 43 there. The corresponding pivot point is the one described above second horizontal pin 60.

Section 75 projecting from an open end the rod 72 guided linearly in the guide cylinder 71 forms a bearing eye 76 there, which over the first, with 59 designated horizontal pegs on the Swivel tab 57 attacks articulated.

The axis constellation is such that the toggle lever 70 towards slide 43 in a relaxed basic position of the clamping tool S has an open angle alpha of a little less than 90 °.

The linear movement of the rod 72 is limited by a stop device 77. It consists of a Sliding path crossing grub screw 78 with its inner end into a longitudinal slot 79 of the rod 72 protrudes. The grub screw 78 holds the two parts 71 and 72 together.

An axially oriented one incorporated into the pressure force limiter Compression spring 80 loads the pull / push rod 58 in its basic position shown in FIG. 24. Here the two journals 59 and 60 take their farthest Distance from each other. Approaching them happens accordingly while compressing the return spring Compression spring 80. They are not shown in detail Precautions have been taken to the corresponding relative shift of the parts to each other an air balance with respect to a spring chamber receiving the compression spring 80 allow. The latter extends between one Pot bottom of the guide cylinder 71 and one of the pot bottom facing end face of the rod 72.

A locking ball 81 acts to limit the pressure force in the joint area between guide cylinder 71 and rod 72 installed. It is under the action of a compression spring 82. The latter loads the detent ball 81 in the locked position, i.e. towards a control pocket 83. Here, the detent ball 81 is supported on a right-hand side Flank 83 '. The bottom half of the ball finds their support at a support point just below the equator 84 of a transverse bore 85 in the lateral wall of the Guide cylinder 71. Said cross bore 85 acts as an alternative space of the locking ball 81. This situation occurs when the flowing in via the edge 83 ' Pressure collapse the resistance of the compression spring 82 leaves. The detent ball 81 emerges as a locking member the joint area out; the counterpart is lost. The pull / push rod 48 is shortened. That means, that over the hand fog 49 via the knee joint none Carpet 3 more exciting force more applied becomes. Rather, only one is set to the Size reached traction reached. The relocation of the Carpet 3 is so gentle on materials and above all Things evenly.

A stroke travel indicator 86 is attached to the pressure force limiter. The can be in the form of a cross notch on the top of section 75 can be realized. Is expedient such a cross notch is highlighted in color. As an index The free end edge 87 of the guide cylinder can be used as a reference 71 serve.

The stop device 77 fulfills yet another Function, namely that of the rotation lock, so that the Locking ball 81 not out of the range of those controlling it Control pocket 83 device. Works when assembled on the other hand, the way of articulation via the journal 59 and 60 for parts 71, 72 to prevent rotation.

The return spring compression spring 80 brings up when pulling up again of the hand lever 49 always the pressure force limiter back to its basic position.

As Figure 24 also shows, the support base of the compression spring 82 changeable with respect to the detent ball 81; about this the preload can be regulated. So it can Pressure force limitation at a larger angle in front of the Extended position of the knee or in a smaller one Angle must be set.
