Abstract
In order to develop a device enabling efficient setting of floor coverings, including prefabricated wood floor or laminated panels, comprising at least one prestressing rail, one limit stop (16) at a first end of the prestressing rail and a first guided-travel fastening element having a first prestressing surface for laying the floor covering material thereupon, it is suggested that a second guided-travel prestressing element be added and secured to the prestressing rail and that a setting device be provided to enable both prestressing elements to be moved away from another.
Description
CA 022~9336 1998-12-22 Laying Device The invention relates to a laying device for floor covering elements, in particular, for the laying of prefabricated parquet flooring or laminated panels, wherein the laminate is a type of prefabricated parquet flooring of less thickness but precise dimensions which comprises plastic-coated panels.
The length of such panels is in the order of magnitude of 1 to 3 m.
During the laying of prefabricated parquet flooring it is important for the first three rows of panels to be laid exactly and glued and not to have any spacing whatsoever between them. In particular, these rows should be pressed together with considerable force so that inaccuracies, such as, for example, warping of the panels, damage and joins can be bridged by the glue necessary for connecting them and coated inbetween.
During the laying of laminated panels it is often not sufficient to lay the first three rows of panels exactly.
The tongues and grooves of the panels fit so exactly into one another that after coating with the necessary glue or adhesive a good fit without any residual gap between the individual panels is not achieved without aids. This also applies for the laying of more than three rows of such laminated panels.
CA 022~9336 1998-12-22 If, in addition, the laminated panels are warped, the laying thereof without any residual gap will be very difficult. The same problems also arise for cross connections. The optical impression, in particular, of such a floor of panels is impaired when a gap occurs in the cross connection of the panels which is larger than normal.
Clamping tools are known which are suitable for clamping the first three rows in the ~ase of prefabricated parquet panels and laminated panels, such as, for example, that described in German patent application P 44 04 310.4.
Furthermore, German Utility Model DE-295 07 795 discloses a laying aid which is also suitable for laminated panels since it is designed in the form of a tape tensioner with a tape and has on both sides a shaped part which is respectively provided with a receiving means for the tape and which can be fixed to panels with a tongue or a groove by engaging in or around them.
The object underlying the invention is therefore to provide a laying device for floor covering elements of the type specified at the outset, with which an efficient laying of floor covering elements is possible.
This object is accomplished in accordance with the invention, in a laying device for floor covering elements, in particular, for prefabricated parquet flooring or laminated panels, comprising at least one clamping rail, an end element provided at a first end of the clamping rail and a first clamping element guided for displacement on the clamping rail and having a first clamping surface for acting on the floor CA 022~9336 1998-12-22 covering elements, in that a second clamping element is arranged on the clamping rail so as to be guided for displacement, that the second clamping element can be secured in position on the clamping rail and that an adjusting means is provided, with which the first and the second clamping elements can be moved away from one another.
The advantage of the inventive solution is to be seen in the fact that with this solution a simple possibility has been created of acting on the first clamping element in the direction away from the second clamping element, wherein for this purpose the second clamping element has to be fixed in position on the clamping rail and the adjusting means has to be actuated.
It is particularly favorable when the second clamping element has a second clamping surface and when the first and the second clamping elements are guided for displacement on the clamping rail such that the first and the second clamping surfaces are arranged to point in opposite directions.
The advantage of this solution is to be seen in the fact that in this case it is possible to act on floor covering elements and clamp them in the direction of the end element or away from it.
In this respect, it is particularly favorable when the first clamping element can also be fixed in position on the clamping rail so that either the first or the second clamping element can be interchangeably fixed on the clamping rail and the possibility is created, due to the movement away from one another of the two clamping elements during actuation of the CA 022~9336 1998-12-22 adjusting means, of either moving the first clamping element away from the second clamping element fixed on the clamping rail or of moving the second clamping element away from the first clamping element fixed on the clamping rail.
With respect to the design of the adjusting means, no further details have so far been given. It would be possible, for example, to provide the adjusting means as an additional element which can be inserted between the clamping elements and moves these relative to one another. A solution which is particularly favorable on account of its simplicity does, however, provide for one element of the adjusting means to be arranged on one of the clamping elements.
A solution which is particularly simple and also easy to handle from a constructional point of view provides for the adjusting means to comprise a spindle.
With respect to the possibility of fixing the first and/or second clamping element on the clamping rail, no further details have so far been given. It would be possible, for example, to design the clamping rail such that the respective clamping element can be secured on this in various positions, for example, positions predetermined by locking fixtures or cams attachable to the clamping rail.
With respect to a simple handling it is, however, more advantageous when the respective clamping element has a fixing means for securing the same on the clamping rail.
The fixing means could likewise comprise locking elements engaging in recesses of the clamping rail. It is particularly favorable, especially in order to obtain CA 022~9336 1998-12-22 a stepless adjustability and securability along the clamping rail, when the fixing means is a gripping fixing means, with which the respective clamping element can be secured on the clamping rail by a non-positive connection. Therefore, all form-locking elements to be provided on the clamping rail can be omitted and so the solution is, on the one hand, constructionally simpler and, on the other hand, easier and more favorable to handle.
In a constructionally preferred case, the fixing means is designed such that it has a gripping screw, with which a gripping jaw can be abutted on the clamping rail in a gripping manner.
With respect to the design of the clamping elements themselves, no further details have so far been given. One advantageous embodiment, for example, provides for at least one of the clamping elements to have a base member which is provided with a rail guide means for the at least one clamping rail and is guided with this along the clamping rail in a defined alignment in relation thereto.
Thus, an alignment of the clamping element relative to the clamping rail which is advantageous for a precise clamping of the floor covering panels is ensured.
Furthermore, it is particularly favorable when the base member bears a clamping jaw with the respective clamping surface. This clamping jaw is thus also movable along the clamping rail aligned in a defined alignment relative to the clamping rail.
CA 022~9336 1998-12-22 Furthermore, an additional, advantageous development of this embodiment provides for the base member to have a bearing part for receiving an element of the adjusting means; thus the base member is likewise designed in a simple manner as support for the element of the adjusting means, wherein it is preferable not only for the adjusting means to act on the base member but also for the base member itself to act on the respective floor element via the clamping jaw.
A solution which is particularly simple from a constructional point of view and in which the adjusting means comprises an adjusting spindle which can act against a pressure surface on the other respective adjusting element provides for the adjusting spindle to be mounted in the bearing part.
A further, advantageous embodiment of the inventive solution provides for a pressure surface for an adjusting spindle of another clamping element acting against this to be provided on the base member.
Furthermore, a favorable development of the inventive solution provides for the base member to have a receiving means for the fixing means and thus to serve, at the same time, for mounting the fixing means.
In conjunction with the preceding explanations concerning the individual embodiments, it has merely been assumed that one of the clamping elements has a base member in accordance with the embodiments described above. One particularly favorable solution does, however, provide for both clamping elements to have a base member in accordance with the advantageous embodiments described above.
. .
CA 022~9336 1998-12-22 A particularly inexpensive solution provides for the base members of the two clamping elements to be of an identical design so that the two clamping elements can be produced from two identical base members.
With respect to the design of the end element, no further details have so far been given. One advantageous embodiment provides for the end element to be detachably arranged on the clamping rail.
It is thus possible to use the inventive parquet laying device either with or without this end element and also utilize the end element separately.
A particularly expedient construction of the end element provides for this to bear a clamping surface facing the first clamping surface of the first clamping element so that floor covering elements can be clamped between the end element and the first clamping element.
Since, in addition, the end element is always arranged near to the wall of the room, in which the floor covering elements are intended to be laid, and the space between the first floor covering element and the wall must be set exactly, one advantageous solution provides for the end element to have a wall support, with which the end element can be supported on the wall.
Such a wall support can serve, on the one hand, to determine the distance of the first floor covering element from the wall but can also, on the other hand, serve to act on a floor covering element with the second clamping element and its CA 022~9336 1998-12-22 second clamping surface in the direction away from the end element, wherein, in this case, the end element merely serves to support the laying device in relation to the wall such that the first clamping element secured on the clamping rail is likewise supported on the wall via the end element and can thus serve to act on the second clamping element, upon actuation of the adjusting means, in the direction away from the wall and to act on a floor covering element with the clamping surface of the second clamping element, likewise in the direction away from the wall.
Particularly when the wall support is intended to serve to specify a defined distance of the first floor covering element located near to the wall, it is preferably provided for a wall spacing of the clamping surface of the end element to be set with the wall support.
A particularly simple design of such a wall support from a constructional point of view provides for the wall support to comprise a spindle, with which a distance from the wall can be set in a simple manner.
With respect to the design of the end element, again no further details have been given. One advantageous embodiment provides for the end element to have a base member like that described in conjunction with the at least one clamping element in several advantageous embodiments. A particularly inexpensive solution provides for the base member of the end element to be of an identical design to the base member of one of the clamping elements or, even better, both clamping elements.
CA 022~9336 1998-12-22 In principle, it is sufficient within the scope of the inventive solution to provide one clamping rail.
An advantageous solution particularly with respect to the parallel alignment of the clamping elements and also a symmetrical support of the clamping elements as well as the end element provides for the end part and the clamping elements to be guided on two clamping rails extending parallel to one another.
In this respect, it is particularly favorable when the clamping elements and the end element extend essentially between the clamping rails.
In the case where a base member is used, the base member extends essentially between the clamping rails.
In this respect, it is then preferably provided for the clamping rails to extend through rail guide means provided on the end element and the clamping elements.
Since the rail guide means ought to ensure as exact a guidance of the end element and the clamping elements as possible relative to one another, they are intended to be designed such that they surround the guide rails at least partially. A particularly favorable solution provides for the rail guide means to surround the clamping rails transversely to their longitudinal direction so as to be non-removable. In this respect, it is particularly favorable when the rail guide means surround the clamping rails essentially completely so that the clamping guide means are movable merely along the clamping rails.
CA 022~9336 1998-12-22 In connection with a base member, one advantageous embodiment provides for the base member to bear the rail guide means.
It is particularly favorable when the rail guide means are formed on the base member, in particular formed in one piece thereon.
In order to configure the inventive laying device, on the one hand, so as to be transportable in a simple manner and, on the other hand, create the possibility of clamping together a great number of floor covering elements with this laying device or of acting on floor covering elements away from a wall at a large distance from this wall, the clamping rails are preferably designed to be separable so that they each comprise, for example, main rails and extension rails attachable thereto.
The extension rails can preferably be connected to the main rails or to one another by means of couplings.
The dimensioning of the clamping surfaces for the most varied of uses is, in many cases, problematic. For example, some laminated panels are very thin and so the dimensioning of the clamping surfaces ought to be carried out in adaptation to the thin laminated panels whereas, on the other hand, prefabricated parquet panels can have a considerably greater thickness.
For this reason, one advantageous embodiment provides for attachment elements to be attachable to the clamping jaws bearing the clamping surfaces. The attachment elements can be designed, for example, such that they are produced from an elastic material in order to act on the panels more gently.
CA 022~9336 1998-12-22 However, the attachment elements also offer the possibility of a different configuration of the clamping surfaces in comparison with the clamping surface of the clamping jaws.
For example, it is provided within the scope of the inventive solution for the attachment elements to have clamping surfaces designed differently from the clamping surfaces of the clamping jaws.
The clamping surfaces can, for example, in the simplest case have a greater extension away from an underside of the end elements or the respective clamping element and thus be more suitable for grasping, for example, thicker panels.
There is, however, also the possibility of shaping the clamping surfaces completely differently, for example, of giving the clamping surfaces a greater inclination in relation to the underside of the end element or the clamping elements.
A further possibility is to design the clamping surfaces such that they can be brought, for example, into form-locking engagement with a tongue or a groove of a panel, wherein in this case the clamping surface is designed such that it bears the counterpart to the groove or to the respective tongue.
In this case, it is, however, necessary to dimension the attachment elements specially for the individual types of panel.
One embodiment of the inventive solution, in particular, creates the possibility of clamping the floor covering elements against one another even at difficult locations in . . .
CA 022~9336 1998-12-22 the room to be laid, wherein either several floor covering elements can be pressed together by means of the laying device or floor covering elements can be pressed away from a wall against other floor covering elements which have already been laid out and fixed in position.
A particularly great advantage of one embodiment of the inventive solution is also to be seen in the fact that, with it, the possibility is created by means of the clamping rails and the rail guide means of guiding the clamping elements and also the end element parallel to one another and preventing, in particular, any tilting up of the floor covering panels as well since the clamping elements and also the end element are aligned relative to one another such that their clamping surfaces counteract any tilting up.
Furthermore, the great flexibility and varying usability of the inventive laying device is ensured by the fact that one of the clamping elements can be guided for displacement on the clamping rails whereas the other clamping element is fixed in position each time and the adjusting means between the clamping elements can be utilized to use the respectively displaceable clamping element for clamping the panels, wherein this is possible alternatingly between the individual clamping elements, depending on the laying task to be performed, and so one of the clamping elements is placed each time on the guide rail and the other is guided for displacement.
In this respect, it is particularly favorable that it is unimportant for the functioning of the two clamping elements and the interchanging of the functions thereof, on which of . . .
CA 022~9336 1998-12-22 the clamping elements which element of the adjusting means is arranged. The functions can be interchanged between the individual clamping elements, wherein the pressure spindle is, for example, arranged each time on one clamping element and this acts each time against the other clamping element and the clamping element fixed relative to the clamping rail then serves as abutment for the other clamping element which is, in this case, movable with the pressure spindle.
With the inventive laying device, the end element can, furthermore, be advantageously used in both cases, wherein the end element either serves with its clamping surface to clamp panels between the first clamping element and the end element or serves to ensure a wall support for the case where floor covering panels are intended to be acted upon by means of the second clamping element away from the wall.
A particlllarly advantageous embodiment of an inventive parquet laying device for the laying of prefabricated parquet flooring and laminated panels, preferably, however, for an exact laying of laminates with two pressure pieces, i.e. one end element and one clamping element, which enclose the respective panels from the side in order to press them together, wherein one of the pressure pieces, i.e. the end element, has an adjustable support abutting on the wall side, with which the distance to the wall can be set, provides for at least a third pressure piece, i.e. an additional clamping element, to be provided in addition. This additional clamping element makes it possible via an adjustment possibility, which can be supported on the respectively other clamping element, either to clamp the panels between the end element and the one clamping element, i.e. the first clamping .. .. , . . . , .. ~. , , CA 022~9336 1998-12-22 element, wherein the first clamping element is displaceable by the second clamping element fixed in position on the clamping rail and the adjustment possibility or to support the laying device on a wall with the end element and act on the panels away from the wall, on which the end element abuts, and in the direction of the opposite wall by means of the outermost clamping element, i.e. the second clamping element, wherein in this case the second clamping element is guided on the clamping rails so as to be freely displaceable and the first clamping element is fixed on the clamping rails.
The end element as well as the clamping elements are preferably guided on the clamping rail or the clamping rails in parallel.
Furthermore, an advantageous embodiment provides for one or several guide means to be provided on the end element and the clamping elements for an exact guidance of these elements on one guide rail or two guide rails.
The guide means are preferably designed such that the clamping rails may be displaced easily and removed from them.
In order to fix the clamping rails on the end element and the clamping elements, a fixing means or a locking fixture is arranged such that when it is actuated both clamping rails can be fixed in position or released at the same time.
In order to act on the clamping elements away from one another, it is preferably provided for the clamping elements CA 022~9336 1998-12-22 or also pressure pieces to comprise as adjustment possibility, i.e. as adjusting device, a nut thread and a spindle arranged therein.
In the case of the end element it is provided for a spindle to likewise be provided for setting the distance thereof from the wall.
In order to be able to move the two clamping elements away from one another in a simple manner, it is provided in one advantageous embodiment for one of the clamping elements to have a support surface or front surface, against which the spindle provided on the other clamping element acts.
In this respect, the spindle provided on the respective clamping element or pressure piece is preferably designed such that it has a pressure plate mounted on this which can be tilted to such an extent that it abuts areally on the corresponding support surface or front surface of the other clamping element, wherein, in this case, one of the clamping elements can be fixed in position on the clamping rails by means of the locking fixture or the fixing elements.
In order, when using two clamping rails, to give these additional guidance, a guiding element is provided in addition which likewise has a locking fixture or a fixing means, with the aid of which, as in the case of the clamping elements, the clamping rail can be fixed in position on the guiding element or be displaced relative to this.
One advantageous embodiment of clamping rails which have several rail sections which can be coupled with one another provides for one of the respective rail sections to have ...... . ..
CA 022~9336 1998-12-22 a guide bolt and a threaded lug and the other of the rail sections to have an inner thread for the threaded lug and a guide bore for the guide bolt so that the rail sections can easily be coupled with one another.

CA 022~9336 1998-12-22 A first embodiment of an inventive parquet laying device, illustrated in Figures 1 and 2, comprises two clamping rails 12a, 12b which extend parallel to one another and bear in the region of their first ends 14a, 14b an end element 16 which, as illustrated in Figures 3 and 4, comprises a base member 20 with a center web 22 which extends between two rail guide means 24a and 24b for the clamping rails 12a, 12b. The rail guide means 24a and 24b are preferably formed by a channel 25 which extends parallel to the respective longitudinal direction 26a, 26b of the corresponding clamping rail and encloses the respective clamping rail 12a, 12b.
The channel 25 is preferably formed by tubular sections 28a, 28b integrally formed on the center web 22 and extending in the direction of the longitudinal directions 26a, 26b of the clamping rails 12a, 12b.
The clamping rails 12a, 12b are preferably designed as rectangular pipes and thus the channel of the rail guide means 24a, 24b also as a rectangular channel which abuts on the clamping rails 12a, 12b on all sides.
In order to fix the ends 14a, 14b of the clamping rails 12a, 12b, the tubular sections 28a, 28b are provided with bores 30a, 30b which are preferably located on an outer side 32a, 32b of the tubular sections 28a, 28b facing away from the center web 22 and into which fixing screws 34 can be screwed, these screws acting non-positively on the ends 14a, 14b of the clamping rails 12a, 12b and securing these in position in the tubular sections 28a, 28b.
CA 022~9336 1998-12-22 Furthermore, the base member 20 is provided with a clamping jaw 36 which extends transversely to the longitudinal directions 26a, 26b, preferably at right angles thereto, and extends, proceeding from the center web 22 as well as the rail guide means 24a, 24b arranged laterally thereof, beyond an underside 38 thereof and is thereby located close to an end side 40 of the base member, wherein a front side 42 of the clamping jaw 36 is preferably aligned with the end side 40 whereas a rear side 44 facing away from this acts as clamping surface and has, in particular, twin teeth.
Expediently, the clamping jaw 36 is integrally formed on the base member 20.
The base member 20 has, in addition, a bearing member 46 which is seated on the center web 22 and bears a nut thread 48 for a spindle 50. Preferably, the bearing member 46 is integrally formed on the center web 22. The spindle 50 engages in the nut thread 48 with a spindle thread 52, wherein a spindle axis 54 of the spindle 50 is located in a plane 56 which extends, on the one hand, between the clamping rails 12a, 12b and parallel to their longitudinal directions 26a, 26b, and wherein the spindle axis 54 is inclined in addition in the direction of a plane 58 defined by the two longitudinal directions 26a, 26b and namely such that a front end 60 of the spindle 50 located closest to the plane 58 projects beyond the end side 40 of the base member 20 and bears a pressure plate 62 which is rotatable in relation to the spindle axis 54 and is, in addition, tiltable in relation to the spindle axis 54 to such an extent that its front side 64 can be positioned to extend at right angles to the plane 58.
CA 022~9336 1998-12-22 Furthermore, the spindle 50 is provided at its rear end facing away from the front end 60 with a turning handle 56 which, with increasing distance from the threaded section 52, likewise extends with increasing distance from the plane 58 and thus preferably extends above the clamping rails 12a, 12b.
The center web 22 of the base member has a front surface 70 which faces the end side 40 and is s~t back in relation to the end side 40 but extends approximately parallel to this and thus approximately at right angles to the plane 58.
In addition, the tubular sections 28a, 28b are provided with bearing housings 72a, b arranged opposite the underside 38, these housings creating a receiving space 74 which is located to the side next to the channel 25 and extends above it and the function of which will be explained in the following.
The end element 16 is arranged at the ends 14a, 14b of the clamping rails 12a, 12b such that the clamping rails 12a, 12b do not protrude beyond the end side 40 but extend in an opposite direction away from the end side 40 so that only the front end 60 of the spindle 50 protrudes beyond the end side 40 with the pressure plate 62.
Moreover, a first clamping element 80 and a second clamping element 90 are guided for displacement on the clamping rails 12a, 12b at a distance from the end element 16, wherein the first clamping element 80 is located between the end element 16 and the second clamping element 90.
CA 022~9336 1998-12-22 The first clamping element 80 has, ~s illustrated in Figures 5 and 6, a base member 20 which is of an identical design to the base member 20 of the end element 16.
In contrast to the end element 16, however, no spindle 50 is arranged in the bearing member 46. Furthermore, fixing means 100 are provided in the case of the first clamping element 80 in the receiving spaces 74 of the bearing housings 72a, 72b, these fixing means having a respective gripping jaw 102 which faces the respective clamping rails 12a, 12b and is provided with a threaded bore 104, into which a gripping screw 106 with an outer thread 108 engages. The gripping screw 106 is, for its part, provided with a support nut llO which is supported with its side 112 facing away from the gripping jaw 102 on an upper housing wall 114 of the bearing housings 72a, 72b so that by turning the gripping screw 106 in such a manner that the gripping jaw 102 can be moved away from the upper housing wall 114 a secure clamping of the respective clamping rail 12a, 12b with a gripping surface 116 of the respective gripping jaw 102 facing it can be achieved with the support nut 110 abutting on the upper housing wall 114.
The gripping screw 106 extends through the upper housing wall 114 as far as an actuating element 118 which is either securely connected to the section of the gripping screw 106 extending beyond the upper housing wall 114 or can be non-rotatably connected via a form-locking surface 120 to a form-locking element 122 with a corresponding configuration on the gripping screw 106 but is releasably connected, wherein the form-locking element 122 is securely connected to the gripping screw 106.
....
CA 022~9336 1998-12-22 Furthermore, for stopping turning of the actuating element 118 a spring element 124 is provided between the upper housing wall 114 and the actuating element 118 and this prevents any free rotatability of the actuating element 118 and thus of the gripping screw 106 without any manual action.
Such fixing means 100 are provided in both bearing housings 72a and 72b of the base member 20 and so the first clamping element 18 can be secured in position on both clamping rails 12a, 12b.
The second clamping element 90 has, as illustrated in Figures 7 and 8, a base member 20 which is of an identical design to the base member 20 of the end element 16 and the base member 20 of the first clamping element 80.
Furthermore, the fixing means 100 already described in conjunction with the first clamping element 80 are provided in the bearing housings 72a and 72b and so the second clamping element 90 can likewise be fixed on the two clamping rails 12a, 12b with the fixing means 100.
In addition, a spindle 50 is arranged in the bearing member 46 and this is designed and mounted identically to the spindle 50 of the end part 16.
With respect to the individual features of the base member 20, the spindle 50 and the fixing means 100 of the second clamping element 90, reference is therefore made in full to the preceding comments and the same reference numerals are used.
CA 022~9336 1998-12-22 The inventive parquet laying device operates, as in a first application illustrated in Figure 9, such that several panels 140a to 140df of prefabricated parquet flooring are glued and laid next to one another with their joins and the inventive parquet laying device is applied such that the end element 16 engages with its clamping jaw 36 over a groove side or groove end 142 of the panel 140a and thereby abuts with the rear side 44, which represents the clamping surface at the same time, on the groove side 142. The groove side 142 of the panel 140a is preferably located close to a wall 144 of a room, in which the panels 140a to 140d are intended to be laid.
In this respect, the end side 40 of the base member 20 of the end element 16 faces the wall 144 and with the pressure plate 62 protruding beyond the end side 40 it is possible by means of the spindle 50 to set the distance of the groove side 142 of the panel 140a from the wall 144 by displacing the base member 20 relative to the wall 144.
On the side of the base member 20 of the element 16 facing away from the end side 40, the clamping rails 12a and 12b extend as far as the first clamping element 80 which, with released fixing means 100, is guided on the clamping rails 12a, 12b so as to slide freely and is displaced to such an extent that its clamping jaw 36 abuts on a tongue side 146 of the panel 140d, preferably acts on a tongue 148 with the rear side 44 of the clamping jaw 36 which represents the clamping surface at the same time. For this purpose, the base member 20 of the first clamping element 80 is pushed onto the clamping rails 12a, 12b turned through 180~ in relation to CA 022~9336 1998-12-22 the base member 20 of the end element 16 so that the end side 40 of the base member 20 of the first clamping element 80 points away from the end element 16.
The second clamping element 90 is pushed onto the clamping rail 12a, 12b in the same orientation as the end element 16 so that the end side 40 of its base member 20 faces the end side 40 of the first clamping element 80. The second clamping element gO is now advanced towards the first clamping element 80 to such an extent that the pressure plate 62 of the spindle 50 of the second clamping element 90 abuts on the front surface 70 of the base member 20 of the first clamping element 80. If the second clamping element 90 is now fixed in position on the clamping rails 12a, 12b by the fixing means 100, the first clamping element 80, which is not fixed in position on the clamping rails 12a, 12b with its fixing means 100, can be displaced in the direction 150 towards the end element 16 by turning the spindle 50 of the second clamping element 90 so that the clamping jaw 36 of the first clamping element 80 acts on the tongue side 146 of the panel 140d and, altogether, the panels 140a to 140d can be clamped between the clamping jaw 36 of the end element 16 and the clamping jaw 36 of the first clamping element 80.
In a second application, illustrated in Figure 10, the end element 16, in the same way as that described for the first application, can abut on the wall 144 of the room with the pressure plate 62 but no panels are provided for clamping between the end element 16 and the first clamping element 80.
In contrast thereto, the second clamping element 90 acts with its clamping jaw 36 on a tongue side 146' of a panel 140d' which is located on a side of the clamping jaw 36 of CA 022~9336 1998-12-22 the second clamping element 90 located opposite the first clamping element 80, wherein the clamping jaw 36, since the second clamping element 90 is placed on the clamping rails 12a, 12b in the same orientation as the end element 16, acts on the tongue side 146' with its rear side 44 as clamping surface.
In this case, the second clamping element 90 is, however, arranged on the clamping rails 12a, 12b so as to be freely displaceable and the first clamping element 80 is secured in position relative to the clamping rails 12a, 12b with the fixing elements 100. Furthermore, the second clamping element 90 is, in this application as well, advanced towards the first clamping element 80 to such an extent that the spindle 50 acts via the pressure plate 62 on the center web 22, in particular, the front surface 70 thereof so that when the spindle 50 of the second clamping element 90 is turned the second clamping element 90 can now be displaced on the clamping rails 12a, 12b away from the end element 16 in the direction 160, wherein the parquet laying device is supported on the wall 144 via the pressure plate 62 of the end element 16 so that the clamping jaw 36 can act on the tongue side 146' of the panel 140d' and displace this likewise in the direction 160 and clamp it in relation to panels already laid out.
Alternatively thereto, it is also conceivable in the second application to secure the second clamping element 90 in position on the clamping rails 12a and to move the unit consisting of end element 16, clamping rails 12a, 12b and second clamping element 90 away from the wall 144 by turning the spindle 50 of the end element 16.
CA 022~9336 l998-l2-22 As described in conjunction with the two applications, it is thus possible with the inventive parquet laying device to act on panels by means of the first clamping element 80 and the second clamping element 90 in the direction 150 towards the end element 16 or in the direction 160 away from the end element 16 and to clamp these against one another, wherein in the case where the panels 140 are acted on in the direction 150 towards the end element 16 it is not necessary for the pressure plate 62 of the end element 16 to be supported on the wall 144 but the distance to the wall can be set with other wall spacer elements whereas during clamping in the direction 160 away from the end element 16 it is absolutely necessary for the end element 16 to be supported on the wall 144.
In order to act more gently on the groove sides 142 and the tongue sides 146 of the panels 140, an attachment element 170 can be placed on the clamping jaws 36, as illustrated in Figure 11, and this can, for example, be produced from an elastic material and forms on opposite sides clamping surfaces 172 and 174 which, in the simplest case, are of a flat design but are inclined in relation to a vertical line 176 to the underside 38 of the respective base member 20 such that the clamping surfaces 172, 174 form with the underside an angle slightly smaller than 90~. Thus the clamping jaw 36 can be prevented from sliding off from, for example, a groove side 142 or a tongue side 146.
Furthermore, the attachment element 170 can be designed such that its clamping surfaces 172, 174 have, proceeding from the underside 38, a greater extension than the rear sides 44 of the clamping jaw 36 and thus the clamping jaw 36 can, for .. ,_. n ' CA 022~9336 1998-12-22 .
example, be dimensioned for the thinnest laminated panel obtainable whereas in the case of thicker laminated panels or even thicker parquet panels a greater extension can be achieved with the attachment element 170 as a result of the clamping surfaces 172 and 174, proceeding from the underside 38 of the base member 20, and so in this case, as well, a secure fixing of the base member 20 on these panels is possible.
The attachment element 170 is preferably provided with a central longitudinal recess 180, into which the clamping jaw 36 engages with essentially its full extension away from the underside 38, and at least one side wall 182 of the longitudinal recess is provided with a contour corresponding to the teeth of the rear side 44.
The side wall 184 of the longitudinal recess 180 located opposite the side wall 82 is also preferably provided with a contour corresponding to the teeth of the rear side 44 so that the attachment element 170 can be placed on the clamping jaw 36 in orientations turned in relation to one another, wherein the clamping jaw 36 can abut with its front side 42 on the respective side wall, in this case the side wall 184 of the longitudinal recess 180, only essentially linearly.
This is unimportant insofar as pressure is exerted merely via the rear side 44 of the clamping jaw, on which the corresponding side wall, in this case the side wall 182, abuts essentially areally.
In a further embodiment of an inventive attachment element 170', illustrated in Figure 12, those elements which are identical to the attachment element illustrated in Figure 11 are given the same reference numerals.
CA 022~9336 1998-12-22 In contrast to the embodiment according to Figure 11, the clamping surface 174 is not of a flat design but rather the attachment part has on the side located opposite the clamping surface 172 an upper inclined surface 186 followed by a side surface 188, wherein a groove 190 is provided in this side surface. The groove 190 serves to accommodate the tongue 148 of a panel 140 so that it is possible, in particular, with the groove 190 to securely clamp the tongue side 146 of a panel without it being possible for the clamping jaw 36 with the attachment element 170' to slip off.
In addition, the longitudinal recess 180 is designed in the same way as in the embodiment of the attachment element illustrated in Figure 11 and so in this respect reference can be made in full to the designs in Figure 11.
In a second embodiment of an inventive parquet laying device, illustrated in Figures 13 and 14, those parts which are identical to those of the first embodiment have been given the same reference numerals and so with respect to their description reference is made in full to the explanations concerning the first embodiment.
As illustrated in Figure 13, only two panels 140a and 140b are, for example, pressed together, in particular, in the second embodiment by the end part 16 and the first clamping element 80 with the aid of the second clamping element 90, as already described in conjunction with the first embodiment for the first application. In this case, the distance of the end element 16 from the wall 144 is set by means of the spindle 50 and selected such that a skirting board 141 covers the gap between the panel 140a and the wall 144.
CA 022~9336 1998-12-22 Furthermore, the end element 16 is fixed in relation to the clamping rails or guide rails 12 by the fixing means 100.
In order to clamp the panels 140a and 140b together, the second clamping element 90 is locked relative to the clamping rails 12 or guide rails with the fixing means lO0, or also designated as a locking fixture.
The locking fixture 100 is designed in the case of the construction of the second embodiment illustrated in conjunction with Figures 13 as well as 15 and 16 such that this has an eccentric 232 which is rotatable about an axis 230, is mounted in bores 234 in the respective base member 20 for rotation about the axis 230 and on account of its eccentricity is braced against the clamping rails 12 during rotation and thus secures the clamping rails 12a, b in position on the base member 20.
During actuation of the spindle 50 of the second clamping element 90, it is possible to displace the pressure plate 62 thereof in the direction of the end element 16 and thus act on a pressure surface 71 on the base member 20 on the first clamping element 80 so that the entire first clamping element 80 is displaceable in the direction of the end element 16 and thus the panels 140a and 140b located between the clamping jaws 36 of the end element 16 and the first clamping element 80 are clamped against one another.
If, in contrast thereto, the panels 140'a are required to be pressed away from the wall 144, the first clamping element 80 is secured in position relative to the clamping rails 12 with . . .
-CA 022~9336 1998-12-22 .
the fixing means 100 and the second clamping element 90 released from the clamping rails 12, whereupon it is then possible with the spindle 50 of the second clamping element 90, by exerting pressure against the inclined surface 71, to press the second clamping element 90 away from the first clamping element 80 and thus also from the wall 144 and to press the panels 140'a in the direction towards a wall extending opposite the wall 144 and press together the panels located between this and the panel 140'a.
When the clamping elements 80, 90 are suitably dimensioned, in particular, designed in a space-saving manner, the parquet laying device can be used for counterpressing until the last panel 140'a has been laid. The last panel must then be clamped with a drawbar.
In Figure 14, the parallel guidance of the first clamping element 80 and the second clamping element 90 by the clamping rails 12a and 12b is illustrated by way of example, wherein the fixing means 100 provided on the respective base member 20 serve to alternately secure the first clamping element 80 or the second clamping element 90, wherein it is possible due to turning of actuating elements 119 thereof to secure both clamping rails 12a, 12b relative to the respective base member 20.
Both the first clamping element 80 and the second clamping element 90 as well as the end element 16 are preferably arranged on the guide rails 12a, 12b so as to be freely displaceable and securable.
. ~ .. . . .
CA 022~9336 1998-12-22 The end element 16 can thus also be removed from the guide rails 12 and used individually as wall spacer element, for example, to the side. However, it is, of course, also possible to utilize the entire parquet laying device for pressing in a transverse direction. In this respect, the first clamping element 80 can, for example, be hooked onto one of the clamping rails 12a or 12b when a possibility for this is provided on the rail.
The clamping rails 12a, 12b are inserted, for example, into a U-shaped recess 240 in the respective base member 20, as illustrated in Figure 14, wherein the U-shaped recess 240 is open upwardly, i.e. on a side facing away from the underside 38 of the base member 20. The clamping rails 12a, 12b can have a round or rectangular cross section.
The clamping rails 12a, 12b are preferably designed such that they comprise main rails 12a1, 12b1, to which extension rails 12a2, 12b2 can be coupled in order to ensure a simple transport possibility.
In Figures 15 and 16, one embodiment of such a coupling 250 is illustrated which allows designs of the parquet laying aid to be supplied which are preferably easy to dispatch. The main rails 12a1 and 12a2 have, for example, as coupling elements pin guide means 254 which are arranged in continuation of inner threads 258 proceeding from one end 256. The extension rails 12a2, 12b2 can be introduced into these pin guide means 254 with guide pins 260 which ensure an axial alignment. These guide pins 160 are followed by a section with an outer thread 262 which can be brought into engagement with the inner thread 258 in order to create a CA 022~9336 1998-12-22 screw connection between the individual main rails 12a1 and 12b1 as well as the extension rails 12a2 and 12b2 attachable thereto which each bear the attachment with the outer thread 262 and the guide pin 260 arranged to follow this as coupling elements which interact with the coupling elements 254 and 258.
In this respect, the attachment with the outer thread 262 protrudes beyond an end face 264 of the respective extension rail 12a2, 12b2 so that following engagement of the coupling elements 260, 262 and 254, 258 the end faces 256 and 264 of the main rails 12a1, 12b1 and the extension rails 12a2, 12b2, respectively, abut on one another.
A further guide element 264 illustrated in Figures 15 and 16 serves to additionally guide the respective ends of the guide rails 12a, 12b. In this respect, a base member 20' is provided which likewise has the U-shaped recesses 240, into which the clamping rails 12a, 12b can be inserted in the same way as in the case of the base members 20 and fixed in position with a fixing means 100 in the manner already described by way of eccentrics, wherein the eccentrics securely clamp the respective clamping rails 12a, 12b in the respective U-shaped recesses 240 when the actuating element 119 is turned.
Generally, the inventive parquet laying device has a span width of 3 m which is sufficient since either the panels can be clamped between the end element 16 and the first clamping element 80 with the inventive parquet laying device or can be clamped in the direction towards an opposite wall by the second clamping element 90 and so laying with such a length . , CA 022~9336 1998-12-22 of the parquet laying device of 3 m is possible up to rooms with 6 m width. Favorable measurements for the main rails 12al, 12bl of the clamping rails 12a, 12b are preferably 1 m and the same length for additional extension rails 12a2, 12b2 respectively attachable to one another.
A further, advantageous embodiment of a coupling 250 between a main rail 12al and an extension rail 12a2 of a separable clamping rail 12a provides for an extension 280 to be provided on the extension rail 12a2, for example, in Figure 17 and this extends from one end 282 of the extension rail and bears at its end a bayonet link 284 which can be brought into engagement with a locking pin 286.
The extension 280 can preferably be inserted into an interior 288 of the main rail 12al which extends from one end 290 thereof into the main rail 12al and is penetrated by the pin 286. It is thus possible, by inserting the extension in a rotary position, in which an insertion path 292 of the bayonet link 284 faces the pin 286 in alignment, to push the bayonet link 284 over the pin 286 and when an end wall 294 of the bayonet link 284 is reached to turn the extension 280 to such an extent that a link surface 296 of the bayonet link 284 located opposite the end face 294 engages around the pin and thus the extension 280 is secured on the pin 286. In this position, the outer surfaces of the main rail 12a and the extension rail 12a2 are then aligned with one another.
The extension 280 is, for its part, preferably anchored in the extension rails 12a2 by an additional extension 298 which is likewise inserted into an interior 300 which extends from the end 282 of the extension rail 12a2 into it and is anchored by a fixing pin 302.
In the same way, it is also possible to connect extension rails 12a2 to additional extension rails 12a2.
The length of such panels is in the order of magnitude of 1 to 3 m.
During the laying of prefabricated parquet flooring it is important for the first three rows of panels to be laid exactly and glued and not to have any spacing whatsoever between them. In particular, these rows should be pressed together with considerable force so that inaccuracies, such as, for example, warping of the panels, damage and joins can be bridged by the glue necessary for connecting them and coated inbetween.
During the laying of laminated panels it is often not sufficient to lay the first three rows of panels exactly.
The tongues and grooves of the panels fit so exactly into one another that after coating with the necessary glue or adhesive a good fit without any residual gap between the individual panels is not achieved without aids. This also applies for the laying of more than three rows of such laminated panels.
CA 022~9336 1998-12-22 If, in addition, the laminated panels are warped, the laying thereof without any residual gap will be very difficult. The same problems also arise for cross connections. The optical impression, in particular, of such a floor of panels is impaired when a gap occurs in the cross connection of the panels which is larger than normal.
Clamping tools are known which are suitable for clamping the first three rows in the ~ase of prefabricated parquet panels and laminated panels, such as, for example, that described in German patent application P 44 04 310.4.
Furthermore, German Utility Model DE-295 07 795 discloses a laying aid which is also suitable for laminated panels since it is designed in the form of a tape tensioner with a tape and has on both sides a shaped part which is respectively provided with a receiving means for the tape and which can be fixed to panels with a tongue or a groove by engaging in or around them.
The object underlying the invention is therefore to provide a laying device for floor covering elements of the type specified at the outset, with which an efficient laying of floor covering elements is possible.
This object is accomplished in accordance with the invention, in a laying device for floor covering elements, in particular, for prefabricated parquet flooring or laminated panels, comprising at least one clamping rail, an end element provided at a first end of the clamping rail and a first clamping element guided for displacement on the clamping rail and having a first clamping surface for acting on the floor CA 022~9336 1998-12-22 covering elements, in that a second clamping element is arranged on the clamping rail so as to be guided for displacement, that the second clamping element can be secured in position on the clamping rail and that an adjusting means is provided, with which the first and the second clamping elements can be moved away from one another.
The advantage of the inventive solution is to be seen in the fact that with this solution a simple possibility has been created of acting on the first clamping element in the direction away from the second clamping element, wherein for this purpose the second clamping element has to be fixed in position on the clamping rail and the adjusting means has to be actuated.
It is particularly favorable when the second clamping element has a second clamping surface and when the first and the second clamping elements are guided for displacement on the clamping rail such that the first and the second clamping surfaces are arranged to point in opposite directions.
The advantage of this solution is to be seen in the fact that in this case it is possible to act on floor covering elements and clamp them in the direction of the end element or away from it.
In this respect, it is particularly favorable when the first clamping element can also be fixed in position on the clamping rail so that either the first or the second clamping element can be interchangeably fixed on the clamping rail and the possibility is created, due to the movement away from one another of the two clamping elements during actuation of the CA 022~9336 1998-12-22 adjusting means, of either moving the first clamping element away from the second clamping element fixed on the clamping rail or of moving the second clamping element away from the first clamping element fixed on the clamping rail.
With respect to the design of the adjusting means, no further details have so far been given. It would be possible, for example, to provide the adjusting means as an additional element which can be inserted between the clamping elements and moves these relative to one another. A solution which is particularly favorable on account of its simplicity does, however, provide for one element of the adjusting means to be arranged on one of the clamping elements.
A solution which is particularly simple and also easy to handle from a constructional point of view provides for the adjusting means to comprise a spindle.
With respect to the possibility of fixing the first and/or second clamping element on the clamping rail, no further details have so far been given. It would be possible, for example, to design the clamping rail such that the respective clamping element can be secured on this in various positions, for example, positions predetermined by locking fixtures or cams attachable to the clamping rail.
With respect to a simple handling it is, however, more advantageous when the respective clamping element has a fixing means for securing the same on the clamping rail.
The fixing means could likewise comprise locking elements engaging in recesses of the clamping rail. It is particularly favorable, especially in order to obtain CA 022~9336 1998-12-22 a stepless adjustability and securability along the clamping rail, when the fixing means is a gripping fixing means, with which the respective clamping element can be secured on the clamping rail by a non-positive connection. Therefore, all form-locking elements to be provided on the clamping rail can be omitted and so the solution is, on the one hand, constructionally simpler and, on the other hand, easier and more favorable to handle.
In a constructionally preferred case, the fixing means is designed such that it has a gripping screw, with which a gripping jaw can be abutted on the clamping rail in a gripping manner.
With respect to the design of the clamping elements themselves, no further details have so far been given. One advantageous embodiment, for example, provides for at least one of the clamping elements to have a base member which is provided with a rail guide means for the at least one clamping rail and is guided with this along the clamping rail in a defined alignment in relation thereto.
Thus, an alignment of the clamping element relative to the clamping rail which is advantageous for a precise clamping of the floor covering panels is ensured.
Furthermore, it is particularly favorable when the base member bears a clamping jaw with the respective clamping surface. This clamping jaw is thus also movable along the clamping rail aligned in a defined alignment relative to the clamping rail.
CA 022~9336 1998-12-22 Furthermore, an additional, advantageous development of this embodiment provides for the base member to have a bearing part for receiving an element of the adjusting means; thus the base member is likewise designed in a simple manner as support for the element of the adjusting means, wherein it is preferable not only for the adjusting means to act on the base member but also for the base member itself to act on the respective floor element via the clamping jaw.
A solution which is particularly simple from a constructional point of view and in which the adjusting means comprises an adjusting spindle which can act against a pressure surface on the other respective adjusting element provides for the adjusting spindle to be mounted in the bearing part.
A further, advantageous embodiment of the inventive solution provides for a pressure surface for an adjusting spindle of another clamping element acting against this to be provided on the base member.
Furthermore, a favorable development of the inventive solution provides for the base member to have a receiving means for the fixing means and thus to serve, at the same time, for mounting the fixing means.
In conjunction with the preceding explanations concerning the individual embodiments, it has merely been assumed that one of the clamping elements has a base member in accordance with the embodiments described above. One particularly favorable solution does, however, provide for both clamping elements to have a base member in accordance with the advantageous embodiments described above.
. .
CA 022~9336 1998-12-22 A particularly inexpensive solution provides for the base members of the two clamping elements to be of an identical design so that the two clamping elements can be produced from two identical base members.
With respect to the design of the end element, no further details have so far been given. One advantageous embodiment provides for the end element to be detachably arranged on the clamping rail.
It is thus possible to use the inventive parquet laying device either with or without this end element and also utilize the end element separately.
A particularly expedient construction of the end element provides for this to bear a clamping surface facing the first clamping surface of the first clamping element so that floor covering elements can be clamped between the end element and the first clamping element.
Since, in addition, the end element is always arranged near to the wall of the room, in which the floor covering elements are intended to be laid, and the space between the first floor covering element and the wall must be set exactly, one advantageous solution provides for the end element to have a wall support, with which the end element can be supported on the wall.
Such a wall support can serve, on the one hand, to determine the distance of the first floor covering element from the wall but can also, on the other hand, serve to act on a floor covering element with the second clamping element and its CA 022~9336 1998-12-22 second clamping surface in the direction away from the end element, wherein, in this case, the end element merely serves to support the laying device in relation to the wall such that the first clamping element secured on the clamping rail is likewise supported on the wall via the end element and can thus serve to act on the second clamping element, upon actuation of the adjusting means, in the direction away from the wall and to act on a floor covering element with the clamping surface of the second clamping element, likewise in the direction away from the wall.
Particularly when the wall support is intended to serve to specify a defined distance of the first floor covering element located near to the wall, it is preferably provided for a wall spacing of the clamping surface of the end element to be set with the wall support.
A particularly simple design of such a wall support from a constructional point of view provides for the wall support to comprise a spindle, with which a distance from the wall can be set in a simple manner.
With respect to the design of the end element, again no further details have been given. One advantageous embodiment provides for the end element to have a base member like that described in conjunction with the at least one clamping element in several advantageous embodiments. A particularly inexpensive solution provides for the base member of the end element to be of an identical design to the base member of one of the clamping elements or, even better, both clamping elements.
CA 022~9336 1998-12-22 In principle, it is sufficient within the scope of the inventive solution to provide one clamping rail.
An advantageous solution particularly with respect to the parallel alignment of the clamping elements and also a symmetrical support of the clamping elements as well as the end element provides for the end part and the clamping elements to be guided on two clamping rails extending parallel to one another.
In this respect, it is particularly favorable when the clamping elements and the end element extend essentially between the clamping rails.
In the case where a base member is used, the base member extends essentially between the clamping rails.
In this respect, it is then preferably provided for the clamping rails to extend through rail guide means provided on the end element and the clamping elements.
Since the rail guide means ought to ensure as exact a guidance of the end element and the clamping elements as possible relative to one another, they are intended to be designed such that they surround the guide rails at least partially. A particularly favorable solution provides for the rail guide means to surround the clamping rails transversely to their longitudinal direction so as to be non-removable. In this respect, it is particularly favorable when the rail guide means surround the clamping rails essentially completely so that the clamping guide means are movable merely along the clamping rails.
CA 022~9336 1998-12-22 In connection with a base member, one advantageous embodiment provides for the base member to bear the rail guide means.
It is particularly favorable when the rail guide means are formed on the base member, in particular formed in one piece thereon.
In order to configure the inventive laying device, on the one hand, so as to be transportable in a simple manner and, on the other hand, create the possibility of clamping together a great number of floor covering elements with this laying device or of acting on floor covering elements away from a wall at a large distance from this wall, the clamping rails are preferably designed to be separable so that they each comprise, for example, main rails and extension rails attachable thereto.
The extension rails can preferably be connected to the main rails or to one another by means of couplings.
The dimensioning of the clamping surfaces for the most varied of uses is, in many cases, problematic. For example, some laminated panels are very thin and so the dimensioning of the clamping surfaces ought to be carried out in adaptation to the thin laminated panels whereas, on the other hand, prefabricated parquet panels can have a considerably greater thickness.
For this reason, one advantageous embodiment provides for attachment elements to be attachable to the clamping jaws bearing the clamping surfaces. The attachment elements can be designed, for example, such that they are produced from an elastic material in order to act on the panels more gently.
CA 022~9336 1998-12-22 However, the attachment elements also offer the possibility of a different configuration of the clamping surfaces in comparison with the clamping surface of the clamping jaws.
For example, it is provided within the scope of the inventive solution for the attachment elements to have clamping surfaces designed differently from the clamping surfaces of the clamping jaws.
The clamping surfaces can, for example, in the simplest case have a greater extension away from an underside of the end elements or the respective clamping element and thus be more suitable for grasping, for example, thicker panels.
There is, however, also the possibility of shaping the clamping surfaces completely differently, for example, of giving the clamping surfaces a greater inclination in relation to the underside of the end element or the clamping elements.
A further possibility is to design the clamping surfaces such that they can be brought, for example, into form-locking engagement with a tongue or a groove of a panel, wherein in this case the clamping surface is designed such that it bears the counterpart to the groove or to the respective tongue.
In this case, it is, however, necessary to dimension the attachment elements specially for the individual types of panel.
One embodiment of the inventive solution, in particular, creates the possibility of clamping the floor covering elements against one another even at difficult locations in . . .
CA 022~9336 1998-12-22 the room to be laid, wherein either several floor covering elements can be pressed together by means of the laying device or floor covering elements can be pressed away from a wall against other floor covering elements which have already been laid out and fixed in position.
A particularly great advantage of one embodiment of the inventive solution is also to be seen in the fact that, with it, the possibility is created by means of the clamping rails and the rail guide means of guiding the clamping elements and also the end element parallel to one another and preventing, in particular, any tilting up of the floor covering panels as well since the clamping elements and also the end element are aligned relative to one another such that their clamping surfaces counteract any tilting up.
Furthermore, the great flexibility and varying usability of the inventive laying device is ensured by the fact that one of the clamping elements can be guided for displacement on the clamping rails whereas the other clamping element is fixed in position each time and the adjusting means between the clamping elements can be utilized to use the respectively displaceable clamping element for clamping the panels, wherein this is possible alternatingly between the individual clamping elements, depending on the laying task to be performed, and so one of the clamping elements is placed each time on the guide rail and the other is guided for displacement.
In this respect, it is particularly favorable that it is unimportant for the functioning of the two clamping elements and the interchanging of the functions thereof, on which of . . .

The functions can be interchanged between the individual clamping elements, wherein the pressure spindle is, for example, arranged each time on one clamping element and this acts each time against the other clamping element and the clamping element fixed relative to the clamping rail then serves as abutment for the other clamping element which is, in this case, movable with the pressure spindle.
With the inventive laying device, the end element can, furthermore, be advantageously used in both cases, wherein the end element either serves with its clamping surface to clamp panels between the first clamping element and the end element or serves to ensure a wall support for the case where floor covering panels are intended to be acted upon by means of the second clamping element away from the wall.
A particlllarly advantageous embodiment of an inventive parquet laying device for the laying of prefabricated parquet flooring and laminated panels, preferably, however, for an exact laying of laminates with two pressure pieces, i.e. one end element and one clamping element, which enclose the respective panels from the side in order to press them together, wherein one of the pressure pieces, i.e. the end element, has an adjustable support abutting on the wall side, with which the distance to the wall can be set, provides for at least a third pressure piece, i.e. an additional clamping element, to be provided in addition. This additional clamping element makes it possible via an adjustment possibility, which can be supported on the respectively other clamping element, either to clamp the panels between the end element and the one clamping element, i.e. the first clamping .. .. , . . . , .. ~. , , CA 022~9336 1998-12-22 element, wherein the first clamping element is displaceable by the second clamping element fixed in position on the clamping rail and the adjustment possibility or to support the laying device on a wall with the end element and act on the panels away from the wall, on which the end element abuts, and in the direction of the opposite wall by means of the outermost clamping element, i.e. the second clamping element, wherein in this case the second clamping element is guided on the clamping rails so as to be freely displaceable and the first clamping element is fixed on the clamping rails.
The end element as well as the clamping elements are preferably guided on the clamping rail or the clamping rails in parallel.
Furthermore, an advantageous embodiment provides for one or several guide means to be provided on the end element and the clamping elements for an exact guidance of these elements on one guide rail or two guide rails.
The guide means are preferably designed such that the clamping rails may be displaced easily and removed from them.
In order to fix the clamping rails on the end element and the clamping elements, a fixing means or a locking fixture is arranged such that when it is actuated both clamping rails can be fixed in position or released at the same time.
In order to act on the clamping elements away from one another, it is preferably provided for the clamping elements CA 022~9336 1998-12-22 or also pressure pieces to comprise as adjustment possibility, i.e. as adjusting device, a nut thread and a spindle arranged therein.
In the case of the end element it is provided for a spindle to likewise be provided for setting the distance thereof from the wall.
In order to be able to move the two clamping elements away from one another in a simple manner, it is provided in one advantageous embodiment for one of the clamping elements to have a support surface or front surface, against which the spindle provided on the other clamping element acts.
In this respect, the spindle provided on the respective clamping element or pressure piece is preferably designed such that it has a pressure plate mounted on this which can be tilted to such an extent that it abuts areally on the corresponding support surface or front surface of the other clamping element, wherein, in this case, one of the clamping elements can be fixed in position on the clamping rails by means of the locking fixture or the fixing elements.
In order, when using two clamping rails, to give these additional guidance, a guiding element is provided in addition which likewise has a locking fixture or a fixing means, with the aid of which, as in the case of the clamping elements, the clamping rail can be fixed in position on the guiding element or be displaced relative to this.
One advantageous embodiment of clamping rails which have several rail sections which can be coupled with one another provides for one of the respective rail sections to have ...... . ..

CA 022~9336 1998-12-22 A first embodiment of an inventive parquet laying device, illustrated in Figures 1 and 2, comprises two clamping rails 12a, 12b which extend parallel to one another and bear in the region of their first ends 14a, 14b an end element 16 which, as illustrated in Figures 3 and 4, comprises a base member 20 with a center web 22 which extends between two rail guide means 24a and 24b for the clamping rails 12a, 12b. The rail guide means 24a and 24b are preferably formed by a channel 25 which extends parallel to the respective longitudinal direction 26a, 26b of the corresponding clamping rail and encloses the respective clamping rail 12a, 12b.
The channel 25 is preferably formed by tubular sections 28a, 28b integrally formed on the center web 22 and extending in the direction of the longitudinal directions 26a, 26b of the clamping rails 12a, 12b.
The clamping rails 12a, 12b are preferably designed as rectangular pipes and thus the channel of the rail guide means 24a, 24b also as a rectangular channel which abuts on the clamping rails 12a, 12b on all sides.
In order to fix the ends 14a, 14b of the clamping rails 12a, 12b, the tubular sections 28a, 28b are provided with bores 30a, 30b which are preferably located on an outer side 32a, 32b of the tubular sections 28a, 28b facing away from the center web 22 and into which fixing screws 34 can be screwed, these screws acting non-positively on the ends 14a, 14b of the clamping rails 12a, 12b and securing these in position in the tubular sections 28a, 28b.
CA 022~9336 1998-12-22 Furthermore, the base member 20 is provided with a clamping jaw 36 which extends transversely to the longitudinal directions 26a, 26b, preferably at right angles thereto, and extends, proceeding from the center web 22 as well as the rail guide means 24a, 24b arranged laterally thereof, beyond an underside 38 thereof and is thereby located close to an end side 40 of the base member, wherein a front side 42 of the clamping jaw 36 is preferably aligned with the end side 40 whereas a rear side 44 facing away from this acts as clamping surface and has, in particular, twin teeth.
Expediently, the clamping jaw 36 is integrally formed on the base member 20.
The base member 20 has, in addition, a bearing member 46 which is seated on the center web 22 and bears a nut thread 48 for a spindle 50. Preferably, the bearing member 46 is integrally formed on the center web 22. The spindle 50 engages in the nut thread 48 with a spindle thread 52, wherein a spindle axis 54 of the spindle 50 is located in a plane 56 which extends, on the one hand, between the clamping rails 12a, 12b and parallel to their longitudinal directions 26a, 26b, and wherein the spindle axis 54 is inclined in addition in the direction of a plane 58 defined by the two longitudinal directions 26a, 26b and namely such that a front end 60 of the spindle 50 located closest to the plane 58 projects beyond the end side 40 of the base member 20 and bears a pressure plate 62 which is rotatable in relation to the spindle axis 54 and is, in addition, tiltable in relation to the spindle axis 54 to such an extent that its front side 64 can be positioned to extend at right angles to the plane 58.
CA 022~9336 1998-12-22 Furthermore, the spindle 50 is provided at its rear end facing away from the front end 60 with a turning handle 56 which, with increasing distance from the threaded section 52, likewise extends with increasing distance from the plane 58 and thus preferably extends above the clamping rails 12a, 12b.
The center web 22 of the base member has a front surface 70 which faces the end side 40 and is s~t back in relation to the end side 40 but extends approximately parallel to this and thus approximately at right angles to the plane 58.
In addition, the tubular sections 28a, 28b are provided with bearing housings 72a, b arranged opposite the underside 38, these housings creating a receiving space 74 which is located to the side next to the channel 25 and extends above it and the function of which will be explained in the following.
The end element 16 is arranged at the ends 14a, 14b of the clamping rails 12a, 12b such that the clamping rails 12a, 12b do not protrude beyond the end side 40 but extend in an opposite direction away from the end side 40 so that only the front end 60 of the spindle 50 protrudes beyond the end side 40 with the pressure plate 62.
Moreover, a first clamping element 80 and a second clamping element 90 are guided for displacement on the clamping rails 12a, 12b at a distance from the end element 16, wherein the first clamping element 80 is located between the end element 16 and the second clamping element 90.
CA 022~9336 1998-12-22 The first clamping element 80 has, ~s illustrated in Figures 5 and 6, a base member 20 which is of an identical design to the base member 20 of the end element 16.
In contrast to the end element 16, however, no spindle 50 is arranged in the bearing member 46. Furthermore, fixing means 100 are provided in the case of the first clamping element 80 in the receiving spaces 74 of the bearing housings 72a, 72b, these fixing means having a respective gripping jaw 102 which faces the respective clamping rails 12a, 12b and is provided with a threaded bore 104, into which a gripping screw 106 with an outer thread 108 engages. The gripping screw 106 is, for its part, provided with a support nut llO which is supported with its side 112 facing away from the gripping jaw 102 on an upper housing wall 114 of the bearing housings 72a, 72b so that by turning the gripping screw 106 in such a manner that the gripping jaw 102 can be moved away from the upper housing wall 114 a secure clamping of the respective clamping rail 12a, 12b with a gripping surface 116 of the respective gripping jaw 102 facing it can be achieved with the support nut 110 abutting on the upper housing wall 114.
The gripping screw 106 extends through the upper housing wall 114 as far as an actuating element 118 which is either securely connected to the section of the gripping screw 106 extending beyond the upper housing wall 114 or can be non-rotatably connected via a form-locking surface 120 to a form-locking element 122 with a corresponding configuration on the gripping screw 106 but is releasably connected, wherein the form-locking element 122 is securely connected to the gripping screw 106.
....
CA 022~9336 1998-12-22 Furthermore, for stopping turning of the actuating element 118 a spring element 124 is provided between the upper housing wall 114 and the actuating element 118 and this prevents any free rotatability of the actuating element 118 and thus of the gripping screw 106 without any manual action.
Such fixing means 100 are provided in both bearing housings 72a and 72b of the base member 20 and so the first clamping element 18 can be secured in position on both clamping rails 12a, 12b.
The second clamping element 90 has, as illustrated in Figures 7 and 8, a base member 20 which is of an identical design to the base member 20 of the end element 16 and the base member 20 of the first clamping element 80.
Furthermore, the fixing means 100 already described in conjunction with the first clamping element 80 are provided in the bearing housings 72a and 72b and so the second clamping element 90 can likewise be fixed on the two clamping rails 12a, 12b with the fixing means 100.
In addition, a spindle 50 is arranged in the bearing member 46 and this is designed and mounted identically to the spindle 50 of the end part 16.
With respect to the individual features of the base member 20, the spindle 50 and the fixing means 100 of the second clamping element 90, reference is therefore made in full to the preceding comments and the same reference numerals are used.
CA 022~9336 1998-12-22 The inventive parquet laying device operates, as in a first application illustrated in Figure 9, such that several panels 140a to 140df of prefabricated parquet flooring are glued and laid next to one another with their joins and the inventive parquet laying device is applied such that the end element 16 engages with its clamping jaw 36 over a groove side or groove end 142 of the panel 140a and thereby abuts with the rear side 44, which represents the clamping surface at the same time, on the groove side 142. The groove side 142 of the panel 140a is preferably located close to a wall 144 of a room, in which the panels 140a to 140d are intended to be laid.
In this respect, the end side 40 of the base member 20 of the end element 16 faces the wall 144 and with the pressure plate 62 protruding beyond the end side 40 it is possible by means of the spindle 50 to set the distance of the groove side 142 of the panel 140a from the wall 144 by displacing the base member 20 relative to the wall 144.
On the side of the base member 20 of the element 16 facing away from the end side 40, the clamping rails 12a and 12b extend as far as the first clamping element 80 which, with released fixing means 100, is guided on the clamping rails 12a, 12b so as to slide freely and is displaced to such an extent that its clamping jaw 36 abuts on a tongue side 146 of the panel 140d, preferably acts on a tongue 148 with the rear side 44 of the clamping jaw 36 which represents the clamping surface at the same time. For this purpose, the base member 20 of the first clamping element 80 is pushed onto the clamping rails 12a, 12b turned through 180~ in relation to CA 022~9336 1998-12-22 the base member 20 of the end element 16 so that the end side 40 of the base member 20 of the first clamping element 80 points away from the end element 16.
The second clamping element 90 is pushed onto the clamping rail 12a, 12b in the same orientation as the end element 16 so that the end side 40 of its base member 20 faces the end side 40 of the first clamping element 80. The second clamping element gO is now advanced towards the first clamping element 80 to such an extent that the pressure plate 62 of the spindle 50 of the second clamping element 90 abuts on the front surface 70 of the base member 20 of the first clamping element 80. If the second clamping element 90 is now fixed in position on the clamping rails 12a, 12b by the fixing means 100, the first clamping element 80, which is not fixed in position on the clamping rails 12a, 12b with its fixing means 100, can be displaced in the direction 150 towards the end element 16 by turning the spindle 50 of the second clamping element 90 so that the clamping jaw 36 of the first clamping element 80 acts on the tongue side 146 of the panel 140d and, altogether, the panels 140a to 140d can be clamped between the clamping jaw 36 of the end element 16 and the clamping jaw 36 of the first clamping element 80.
In a second application, illustrated in Figure 10, the end element 16, in the same way as that described for the first application, can abut on the wall 144 of the room with the pressure plate 62 but no panels are provided for clamping between the end element 16 and the first clamping element 80.
In contrast thereto, the second clamping element 90 acts with its clamping jaw 36 on a tongue side 146' of a panel 140d' which is located on a side of the clamping jaw 36 of CA 022~9336 1998-12-22 the second clamping element 90 located opposite the first clamping element 80, wherein the clamping jaw 36, since the second clamping element 90 is placed on the clamping rails 12a, 12b in the same orientation as the end element 16, acts on the tongue side 146' with its rear side 44 as clamping surface.
In this case, the second clamping element 90 is, however, arranged on the clamping rails 12a, 12b so as to be freely displaceable and the first clamping element 80 is secured in position relative to the clamping rails 12a, 12b with the fixing elements 100. Furthermore, the second clamping element 90 is, in this application as well, advanced towards the first clamping element 80 to such an extent that the spindle 50 acts via the pressure plate 62 on the center web 22, in particular, the front surface 70 thereof so that when the spindle 50 of the second clamping element 90 is turned the second clamping element 90 can now be displaced on the clamping rails 12a, 12b away from the end element 16 in the direction 160, wherein the parquet laying device is supported on the wall 144 via the pressure plate 62 of the end element 16 so that the clamping jaw 36 can act on the tongue side 146' of the panel 140d' and displace this likewise in the direction 160 and clamp it in relation to panels already laid out.
Alternatively thereto, it is also conceivable in the second application to secure the second clamping element 90 in position on the clamping rails 12a and to move the unit consisting of end element 16, clamping rails 12a, 12b and second clamping element 90 away from the wall 144 by turning the spindle 50 of the end element 16.
CA 022~9336 l998-l2-22 As described in conjunction with the two applications, it is thus possible with the inventive parquet laying device to act on panels by means of the first clamping element 80 and the second clamping element 90 in the direction 150 towards the end element 16 or in the direction 160 away from the end element 16 and to clamp these against one another, wherein in the case where the panels 140 are acted on in the direction 150 towards the end element 16 it is not necessary for the pressure plate 62 of the end element 16 to be supported on the wall 144 but the distance to the wall can be set with other wall spacer elements whereas during clamping in the direction 160 away from the end element 16 it is absolutely necessary for the end element 16 to be supported on the wall 144.
In order to act more gently on the groove sides 142 and the tongue sides 146 of the panels 140, an attachment element 170 can be placed on the clamping jaws 36, as illustrated in Figure 11, and this can, for example, be produced from an elastic material and forms on opposite sides clamping surfaces 172 and 174 which, in the simplest case, are of a flat design but are inclined in relation to a vertical line 176 to the underside 38 of the respective base member 20 such that the clamping surfaces 172, 174 form with the underside an angle slightly smaller than 90~. Thus the clamping jaw 36 can be prevented from sliding off from, for example, a groove side 142 or a tongue side 146.
Furthermore, the attachment element 170 can be designed such that its clamping surfaces 172, 174 have, proceeding from the underside 38, a greater extension than the rear sides 44 of the clamping jaw 36 and thus the clamping jaw 36 can, for .. ,_. n ' CA 022~9336 1998-12-22 .
example, be dimensioned for the thinnest laminated panel obtainable whereas in the case of thicker laminated panels or even thicker parquet panels a greater extension can be achieved with the attachment element 170 as a result of the clamping surfaces 172 and 174, proceeding from the underside 38 of the base member 20, and so in this case, as well, a secure fixing of the base member 20 on these panels is possible.
The attachment element 170 is preferably provided with a central longitudinal recess 180, into which the clamping jaw 36 engages with essentially its full extension away from the underside 38, and at least one side wall 182 of the longitudinal recess is provided with a contour corresponding to the teeth of the rear side 44.
The side wall 184 of the longitudinal recess 180 located opposite the side wall 82 is also preferably provided with a contour corresponding to the teeth of the rear side 44 so that the attachment element 170 can be placed on the clamping jaw 36 in orientations turned in relation to one another, wherein the clamping jaw 36 can abut with its front side 42 on the respective side wall, in this case the side wall 184 of the longitudinal recess 180, only essentially linearly.
This is unimportant insofar as pressure is exerted merely via the rear side 44 of the clamping jaw, on which the corresponding side wall, in this case the side wall 182, abuts essentially areally.
In a further embodiment of an inventive attachment element 170', illustrated in Figure 12, those elements which are identical to the attachment element illustrated in Figure 11 are given the same reference numerals.
CA 022~9336 1998-12-22 In contrast to the embodiment according to Figure 11, the clamping surface 174 is not of a flat design but rather the attachment part has on the side located opposite the clamping surface 172 an upper inclined surface 186 followed by a side surface 188, wherein a groove 190 is provided in this side surface. The groove 190 serves to accommodate the tongue 148 of a panel 140 so that it is possible, in particular, with the groove 190 to securely clamp the tongue side 146 of a panel without it being possible for the clamping jaw 36 with the attachment element 170' to slip off.
In addition, the longitudinal recess 180 is designed in the same way as in the embodiment of the attachment element illustrated in Figure 11 and so in this respect reference can be made in full to the designs in Figure 11.
In a second embodiment of an inventive parquet laying device, illustrated in Figures 13 and 14, those parts which are identical to those of the first embodiment have been given the same reference numerals and so with respect to their description reference is made in full to the explanations concerning the first embodiment.
As illustrated in Figure 13, only two panels 140a and 140b are, for example, pressed together, in particular, in the second embodiment by the end part 16 and the first clamping element 80 with the aid of the second clamping element 90, as already described in conjunction with the first embodiment for the first application. In this case, the distance of the end element 16 from the wall 144 is set by means of the spindle 50 and selected such that a skirting board 141 covers the gap between the panel 140a and the wall 144.
CA 022~9336 1998-12-22 Furthermore, the end element 16 is fixed in relation to the clamping rails or guide rails 12 by the fixing means 100.
In order to clamp the panels 140a and 140b together, the second clamping element 90 is locked relative to the clamping rails 12 or guide rails with the fixing means lO0, or also designated as a locking fixture.
The locking fixture 100 is designed in the case of the construction of the second embodiment illustrated in conjunction with Figures 13 as well as 15 and 16 such that this has an eccentric 232 which is rotatable about an axis 230, is mounted in bores 234 in the respective base member 20 for rotation about the axis 230 and on account of its eccentricity is braced against the clamping rails 12 during rotation and thus secures the clamping rails 12a, b in position on the base member 20.
During actuation of the spindle 50 of the second clamping element 90, it is possible to displace the pressure plate 62 thereof in the direction of the end element 16 and thus act on a pressure surface 71 on the base member 20 on the first clamping element 80 so that the entire first clamping element 80 is displaceable in the direction of the end element 16 and thus the panels 140a and 140b located between the clamping jaws 36 of the end element 16 and the first clamping element 80 are clamped against one another.
If, in contrast thereto, the panels 140'a are required to be pressed away from the wall 144, the first clamping element 80 is secured in position relative to the clamping rails 12 with . . .
-CA 022~9336 1998-12-22 .
the fixing means 100 and the second clamping element 90 released from the clamping rails 12, whereupon it is then possible with the spindle 50 of the second clamping element 90, by exerting pressure against the inclined surface 71, to press the second clamping element 90 away from the first clamping element 80 and thus also from the wall 144 and to press the panels 140'a in the direction towards a wall extending opposite the wall 144 and press together the panels located between this and the panel 140'a.
When the clamping elements 80, 90 are suitably dimensioned, in particular, designed in a space-saving manner, the parquet laying device can be used for counterpressing until the last panel 140'a has been laid. The last panel must then be clamped with a drawbar.
In Figure 14, the parallel guidance of the first clamping element 80 and the second clamping element 90 by the clamping rails 12a and 12b is illustrated by way of example, wherein the fixing means 100 provided on the respective base member 20 serve to alternately secure the first clamping element 80 or the second clamping element 90, wherein it is possible due to turning of actuating elements 119 thereof to secure both clamping rails 12a, 12b relative to the respective base member 20.
Both the first clamping element 80 and the second clamping element 90 as well as the end element 16 are preferably arranged on the guide rails 12a, 12b so as to be freely displaceable and securable.
. ~ .. . . .
CA 022~9336 1998-12-22 The end element 16 can thus also be removed from the guide rails 12 and used individually as wall spacer element, for example, to the side. However, it is, of course, also possible to utilize the entire parquet laying device for pressing in a transverse direction. In this respect, the first clamping element 80 can, for example, be hooked onto one of the clamping rails 12a or 12b when a possibility for this is provided on the rail.
The clamping rails 12a, 12b are inserted, for example, into a U-shaped recess 240 in the respective base member 20, as illustrated in Figure 14, wherein the U-shaped recess 240 is open upwardly, i.e. on a side facing away from the underside 38 of the base member 20. The clamping rails 12a, 12b can have a round or rectangular cross section.
The clamping rails 12a, 12b are preferably designed such that they comprise main rails 12a1, 12b1, to which extension rails 12a2, 12b2 can be coupled in order to ensure a simple transport possibility.
In Figures 15 and 16, one embodiment of such a coupling 250 is illustrated which allows designs of the parquet laying aid to be supplied which are preferably easy to dispatch. The main rails 12a1 and 12a2 have, for example, as coupling elements pin guide means 254 which are arranged in continuation of inner threads 258 proceeding from one end 256. The extension rails 12a2, 12b2 can be introduced into these pin guide means 254 with guide pins 260 which ensure an axial alignment. These guide pins 160 are followed by a section with an outer thread 262 which can be brought into engagement with the inner thread 258 in order to create a CA 022~9336 1998-12-22 screw connection between the individual main rails 12a1 and 12b1 as well as the extension rails 12a2 and 12b2 attachable thereto which each bear the attachment with the outer thread 262 and the guide pin 260 arranged to follow this as coupling elements which interact with the coupling elements 254 and 258.
In this respect, the attachment with the outer thread 262 protrudes beyond an end face 264 of the respective extension rail 12a2, 12b2 so that following engagement of the coupling elements 260, 262 and 254, 258 the end faces 256 and 264 of the main rails 12a1, 12b1 and the extension rails 12a2, 12b2, respectively, abut on one another.
A further guide element 264 illustrated in Figures 15 and 16 serves to additionally guide the respective ends of the guide rails 12a, 12b. In this respect, a base member 20' is provided which likewise has the U-shaped recesses 240, into which the clamping rails 12a, 12b can be inserted in the same way as in the case of the base members 20 and fixed in position with a fixing means 100 in the manner already described by way of eccentrics, wherein the eccentrics securely clamp the respective clamping rails 12a, 12b in the respective U-shaped recesses 240 when the actuating element 119 is turned.
Generally, the inventive parquet laying device has a span width of 3 m which is sufficient since either the panels can be clamped between the end element 16 and the first clamping element 80 with the inventive parquet laying device or can be clamped in the direction towards an opposite wall by the second clamping element 90 and so laying with such a length . , CA 022~9336 1998-12-22 of the parquet laying device of 3 m is possible up to rooms with 6 m width. Favorable measurements for the main rails 12al, 12bl of the clamping rails 12a, 12b are preferably 1 m and the same length for additional extension rails 12a2, 12b2 respectively attachable to one another.
A further, advantageous embodiment of a coupling 250 between a main rail 12al and an extension rail 12a2 of a separable clamping rail 12a provides for an extension 280 to be provided on the extension rail 12a2, for example, in Figure 17 and this extends from one end 282 of the extension rail and bears at its end a bayonet link 284 which can be brought into engagement with a locking pin 286.
The extension 280 can preferably be inserted into an interior 288 of the main rail 12al which extends from one end 290 thereof into the main rail 12al and is penetrated by the pin 286. It is thus possible, by inserting the extension in a rotary position, in which an insertion path 292 of the bayonet link 284 faces the pin 286 in alignment, to push the bayonet link 284 over the pin 286 and when an end wall 294 of the bayonet link 284 is reached to turn the extension 280 to such an extent that a link surface 296 of the bayonet link 284 located opposite the end face 294 engages around the pin and thus the extension 280 is secured on the pin 286. In this position, the outer surfaces of the main rail 12a and the extension rail 12a2 are then aligned with one another.
The extension 280 is, for its part, preferably anchored in the extension rails 12a2 by an additional extension 298 which is likewise inserted into an interior 300 which extends from the end 282 of the extension rail 12a2 into it and is anchored by a fixing pin 302.
In the same way, it is also possible to connect extension rails 12a2 to additional extension rails 12a2.
