Description

The invention relates to a laying aid for laying Pre-finished parquet and laminate, a kind of pre-finished parquet less Dimension made of plastic and not wood-like Materials such as finished parquet.

The length of these parquet panels is 1 to 3m.

When laying it is important that the first three rows of the Panels are laid exactly and no space between them have to be clamped together with high force are so that inaccuracies (delay), damage and the coated glue bridged for connection can be.

Especially the handyman who lays his floor himself, does not necessarily follow the rule of the three rows and should possibly also other, especially longer lengths can tension.

The clamping should be done gently and with a tool for both floor panel types.

From DE-U-88 16 166 is a tensioning device at the beginning known type known. With this clamping device the tape becomes firm with the flooring elements and under this is routed and aligned, since the tape to the give each adjustable holding part a guide got to.

The device is tensioned by one on one the eccentrics or toggle levers provided, which in a groove of a floor covering element to be tensioned intervenes.

DE 43 04 992 A1 describes a device for tensioning Known floorboards that have jaws, one of which one is connected to a rack and the other one Housing with a gear wheel meshing with the rack wearing.

The invention has for its object a laying aid to create, which also the layman and those who invent Lay flooring elements only once, one too is manageable help and is still inexpensive.

This task is with a laying aid for a groove and a spring-covering floor covering elements, in particular Pre-finished parquet, laminate or floor panels, including a first holding part, which on one of the flooring elements is fixable, and one in a first shot on the first Holding part held tape according to the invention solved in that a second holding part is provided, which on one of the Flooring elements can be fixed and with a second receptacle is provided for the tape that the holding parts as molded parts are formed and one on the flooring elements Placeable base plate with one protruding from it Have legs that the receptacle is arranged on the respective base plate in such a way that the tape is held above and close to the floor covering elements during use, and that to tighten the Floor covering elements acting on the tape and this rolling tensioning element is provided.

The advantage of the solution according to the invention can be seen in that a laying aid is provided with this, which is easy to use and inexpensive.

Alternatively, it is advantageously provided that one the molded parts are provided with the clamping element.

The ratchet tensioner is particularly easy to use with the molded part connect if this is a holding element for the clamping element having.

To further ensure that the tape is as deep as possible the flooring elements is guided is advantageous provided that as a receptacle for the band on which the tensioning element supporting molded part is arranged.

Another inexpensive parquet laying aid provides that Clamping element is attached to one of the bent parts, whereby a hold-down is dispensed with, but only one End loop needed.

The tensioning of the tape can be done in many different ways Way. An advantageous embodiment sees before that the band can be tensioned using a ratchet tensioner is.

This ratchet tensioner can be used when using a hold-down device be arranged on the hold-down device.

Another practical embodiment of the parquet laying aid provides that the bent sheet metal part is designed in this way is that existing holes are used for attachment on the bent sheet metal part together with a pull on the bent sheet metal part to lock the ratchet tensioner.

Another advantageous parquet laying aid provides that a lead-through groove in the bent sheet metal part below the roll-up axis is provided for the necessary deep guidance of the tape on the panels.

The band can advantageously be fixed on one side to the bent part and the second side can be used for tensioning be used.

Known tensioners, for example, can be used for belt tensioning be used, the best known is that of lashing straps is used. This is one made from sheet metal parts Ratchet tensioner, with the strap around the ratchet axis is wound up.

Such a ratchet tensioner can be directly on one side Bending part to be attached or on a third part itself are in the middle of the band, also for simultaneous Stabilization can be arranged.

An expedient solution provides that the parquet laying aid in the form of a belt tensioner with e.g. a ratchet tensioner, as used for lashing straps, for winding and tensioning the belt and carried on both sides one sheet metal part is provided.

A particularly favorable solution provides that the leg each base plate is provided with a projection. Here preferably one of the legs engages in a groove and another engages behind a spring.

So this solution allows by the engaging in grooves or springs engaging behind a secure fixation on the flooring elements so that there is no danger of slipping the molded parts.

Furthermore, it is, in particular, an inexpensive manufacture provided that the projection with which the molding is fixable on the flooring elements, a Bend of the leg forms.

This bend and the leg are preferably dimensioned such that that the turn in the groove of the flooring elements fits in and that with this also a spring of the flooring elements is reachable.

For hanging in a practical embodiment uses a simple bent part that is as identical as possible on each side, whose turn must be so designed; that it is for all possible flooring elements and all types of parquet can be used for both sides, i.e. both the groove and also the feather side.

To the hinge side, it must be designed so that one possible deep tape guidance takes place when the tape is guided in Even a small height is a tipping up of the tensioned Fear panels.

The molded parts are preferably designed as bent sheet metal parts. A solution in which the Sheet metal parts in the length of the legs and in the second turn have the same design and dimensions, that the second turn in the finished parquet groove and laminate groove fits in and with the same dimensions the finished parquet spring and grips the laminate spring without slipping and the tape in the lowest possible position along the panels can be performed.

With the laying aids known so far, the exact distance defined to the wall with strips or wedges. A special one simple training of the solution according to the invention sees before that the molded part with a distance from the wall Support element is provided.

This support element can be firmly arranged in the simplest way be and thus specify a fixed distance.

However, it is particularly advantageous if with the support element the distance between the molded part and the wall is adjustable.

To furthermore, in particular with different inclinations of the Molding relative to the wall and therefore different Inclination of the support element relative to the wall also one provide safe and damage-free support for the wall, is expediently the support element with a convex domed head, which can be placed on the wall is.

Another advantageous parquet laying aid provides that the bent part to the wall has a support element for adjustment the distance to the wall, preferably with a concave one Head to compensate for the possible inclination of the bent sheet metal part.

In an advantageous embodiment of the invention Solution, which is especially about a To avoid raising or folding up the flooring elements, it is preferably provided that the laying aid has a hold-down, which is expedient is arranged between the molded parts.

The hold-down is advantageously designed so that it extends so far in the direction of the tape that it is a middle flooring element completely and two to the side of the middle arranged floor covering elements partially overlaps.

However, such a hold-down device is not absolutely necessary. It is also possible to use one according to the invention Belt tensioner without such a hold-down.

Another advantageous parquet laying aid provides that centered over several, for example the first three panels a hold-down is provided, which is also part of each adjacent row, for example the first row and third row covered.

A first embodiment of a designated 10 in Fig. 1 Laying aid for laying three, for example Panels 14, 14 'and 14 ", comprises a hold-down device 12, which the middle panels 14 'and on both sides thereof lying joint joints 15 and 15 'and partly also over panels 14 and 14 " extends.

Starting from the hold-down device 12, one runs at a fixed point 18 of the hold-down device 12 is held at the end 16 through the hold-down device 12 and along an underside 13 of the same in the direction of one designated as a whole by 20 first molded part, which in the simplest case as a bent part is made of sheet metal. The band 16 forms on his one end of the molded part 20 as a whole with the 22nd designated fixed loop or loop, which in a recording 20b, for example designed as a tab of the molded part 20, is fixed to the molded part 20.

This is the molded part 20 in at a fixed length of the band 16 fixed distance from the hold-down device 12.

Opposite the first molded part 20 is a second molded part 24 provided, starting from which also with a loop 28 in a receptacle 24b of the molded part 24 fixed band 26 runs to the hold-down device 12 and extends lengthways an underside 13 of the hold-down device 12 extends up to a lead through the hold-down device 12 and after passing through the hold-down device 12 to a clamping element runs, which for example also as a so-called commercial ratchet tensioner is formed.

It is for the function of the laying aid according to the invention essential that the bands 16 and 26 as deep as possible on or over the panels 14, 14 'and 14 ", if possible resting on them, are led to a premature tilting of the panels to avoid.

In an advantageous variant of the molded parts according to the invention 20 or 24 is provided for this to be defined Positioning a distance thereof from a wall 21 have a support element 17 which, for example, as Screw formed with a convex or arched head is. The support element in the form of the screw is in a protruding from the molded part above the panels 14 Wall area 23 screwed, so that the Screw trained support element 17 transverse to the wall 21 with its axis 17a extends and thus depending on the screw depth 23 different distances of the molded part in the wall area 20 of the wall 21 are definable.

The molded part 20 also has a leg 19, which transversely to a base plate 20a carrying the receptacle 20b of the molded part 20 and extends, for example, as a bend manufactured projection 25 carries.

The leg 19 is designed so that it has a longitudinal side edge overlaps an outer panel 14 and engages with the projection 25 in a groove 27 of the same. If the panels 14, 14 'and 14 "are panels from so-called laminate, a kind of finished parquet less Dimension made of plastic and not wood-like Materials such as finished parquet, so the base plate 20a run obliquely to an upper side of the panels 14.

The molded part 24 is also designed in the same way, wherein in this case the projection 25 has a spring 29 on a longitudinal side edge the outermost panels 14 ", preferably also made of laminate, reaches behind.

Are made of laminate panels 14, 14 'and 14 " Pre-finished parquet used, as shown in Fig. 2, which in particular has a greater thickness, so are the Leg 19 of the molded parts 20 and 24 is also sufficient long, so that the projection 25 when lying on the panels Base plate 20a, 34a is either able to in a To engage groove 33 of the panels or a tongue 31 thereof to fall behind.

In an advantageous variant of the first embodiment A hold-down device 12 covers the two connecting joints 15 of the three panels 14 to 14 ". The band 16 runs from a fixed point 18 on the hold-down device 12 through a tab of the bent part 20 and ends as a fixed loop 22, band 16 has therefore a fixed length. From the bent part 24 on the opposite side runs the piece of tape 26 from an end loop 28 to Hold-down device 12 and through it to the clamping element used. To function it is essential that the tape 16 and 26 deep the panels are guided to avoid tipping. On one of the bent parts can be used to fix the distance Wall 21 e.g. a screw 17 with a concave head shape in the vertically arranged wall of the bent part can be provided.

In a second embodiment of an inventive Laying aid, shown in FIG. 2, includes the molded part 30 not a support element, but is with respect to the leg 19 and the projection 25 are formed in the same manner as that Molded parts 20 or 24. Otherwise, the molded part 30 also has the receptacle 20b for an end loop 32 of a band 36, which is thereby connected to the molded part 30.

In contrast to the first embodiment, however second molded part 34 is not designed as the first molded part 30, but a base plate 34a thereof is enlarged executed, for mounting a clamping element immediately on the molded part 34.

The molded part 34 still has one as in the Shaped parts 20 and 24 formed leg 19 with a projection 25 on, in the same way as for the molded parts 20 and 24 can be used to fix the same.

The band 36 held on the molded part 30 with the loop 32 is deep on the panels 14, preferably on a surface the same lying on, guided along and runs to second molded part 34, then preferably along an underside 34u of the same and is through the one base plate 34a of the same led through to a drawing not shown Clamping element. In contrast to the first embodiment includes the second embodiment of the invention Laying aid, shown in Fig. 2 none Hold-down device 12 and can be used when lifting off Panels 14 is not to be feared from an underground or is ensured in another way or on a Support via three panels is dispensed with.

An expedient embodiment of the molded part 34 is shown in FIG. 3 shown. In this solution is on the molded part 34 as Clamping element a so-called 40 as a whole Ratchet tensioner mounted as it is generally used for tensioning of tapes or belts is commercially available. For example becomes one of the company Karl Stark GmbH & Co. KG, PO Box 12 54, Anhauserstraße 7, Herbrechtingen as Type 01802/4 or 01802YY offered ratchet tensioner used.

That deep on the panels as well as an underside 34u Base plate 34a of the molded part 34 is guided along the band 36 through an opening 38 through the base plate 34a of the molded part 34 through to a winding axis 42 of the ratchet tensioner 40 performed, preferably the breakthrough 38th lies below the roll-up axis 42. That through the roll-up axis 42 of the ratchet tensioner 40 is passed through the band 36 is by train in the direction of an arrow 43 as far as by the Rolling axis 42 pulled through that a bias is possible is.

The ratchet tensioner 40 has a tensioning lever 44 on the one hand and on the other hand a ratchet tensioner body 45 which is fixed to the molded part 34, for example, in that a raised wall area 46 of the molded part 34 with the Ratchet tensioner body 45, for example via a bore 39, connected is. Furthermore, the ratchet tensioner body 45 by means of a hook-shaped element 41, also as Designated passage, fixed to the molded part 34.

By operating the tensioning lever 44 in the direction of the ratchet tensioner body 45 along an arrow 47 is the band in known manner on the reel axis 42 and thus the panels 14 are clamped together by means of the band 36 feasible by means of the molded parts 30 and 34. The respective The position of the roll-up axis 42 is at one such known ratchet tensioner usual ratchet fixed, which prevents the roll-up axle from rolling back.

For an advantageous variant of the second embodiment is shown in Fig. 2 as once the two Bent parts fit into the grooves and tongues of finished parquet, these being bent parts, which are dimensionally the versions 20 and 24 correspond to laminate, and another to one central position of the clamping element is dispensed with.

The bent part 30 is shown without a support element 17. The Bending part 34 is shown enlarged to put on known clamping element. The band 36 has 30 on the bent part an end loop 32 and is again deep along the panels led up to the bent part 34 and through this the attached Clamping element supplied. This embodiment according to FIG. 2 is to be selected if panels 14 to 14 go up 14 "is not to be feared or is supported on the three panels is dispensed with.

FIG. 3 shows the known ratchet tensioner, in total 40 characterized, connected to the bent part 34 as in FIG. 2 shown. It is important again that the tape is deep on the Panels is guided along and only through a groove 38 below the winding axis 42 is guided to this. Volume 36 is drawn in the zero position and is in the direction of the arrow adjusted and preloaded. By operating the clamping lever 44 in the direction of the arrow, the tape is applied in a known manner Winding axis 42 wound. A ratchet on this axis prevents rising.
