Description

The invention relates to a clamping tool in the manner of a screw clamp, for Laying finished parquet, like panels on ceilings and walls, with groove and spring in lengths of 1 to 2 m is laid on the floor.

For this installation, at least the first 3 rows of panels must be be laid with exact dimensions taking into account wall unevenness. If these are glued firmly, it is easy to lay the remaining rows.

Due to inaccuracies in tongue and groove or damage to the same and by inserting glue between tongue and groove, it is advantageous if these first three rows are pressed exactly with high force.

Of course, this should still be done in a directional clamping mode. Come in addition, that it must also be done gently to prevent further damage to the panee to avoid le.

A device from DE 93 12 852 U1 is for laying prefabricated parquet known, consisting of a parquet iron, d. H. an elongated Flat iron on which a piston is attached, which can be operated by a pair of toggle levers. Its rear end has a claw-like edge. With this device, however, only the penultimate row of panels to the already installed panels can be pressed.

Right-angled slide bars are known from the FR  431.822 with an additional clamp for moving and from DE 31 52 016 A1, as a clamping tool with a slide rail, on which a clamping surface having clamping arm is slidably guided. However, both have Versions for clamping straight clamping surfaces, not the required ones angled.

Rails with sliding slide bracket and spindle are also in the DE 85 02 921 U1 and DE 89 03 875 U1 mentioned.

A tool as it is needed for the realization of the invention idea, cannot be found among those who have become known, especially not for bracing common floor coverings.

The invention has for its object to provide a device with the properties mentioned at the beginning with a possibility of adjustment of the distance to the wall in order to prevent unevenness even on raw walls bypass and this distance to the wall according to the baseboard thickness to keep dimensions even.

This object is achieved by a clamping tool with the features of claim 1.

Here is on the rail a screw clamp with a right-angled slide bracket as Counterpart serving upper part secured against rotation, between Pre-finished parquet and wall engages in one dimension, which is below the heights measured from baseboards. The distance to the wall can be adjusted with a Bridging the adjusting element also different distances. These can be found at Place the screw clamps at intervals of approximately 1 m.  

As loose, not on the The upper part without rail is also attached to the rail lateral and all-round support to be used. Further features emerge from subclaims 2-5.

In the following the invention will be described in more detail in connection with the Drawings explained.

These show:

Fig. 1 is a side sectional view of the rectangular-shaped part which is fixed to the rail,

FIG. 2 is a view rotated 90 ° from the rail direction considered,

Fig. 3 is a plan view,

Fig. 4 is a plan view with finished parquet and sliding bracket, and on the right side the loose top as a side spacer.

Fig. 5 section AA of Fig. 4 with support of finished parquet with less thickness or laminate.

With ( 10 ) the upper part is designated as a whole, the z. B. according to FIG. 1 by rivets ( 11 ) with the rail ( 12 ). The short leg ( 13 ) of the L-shaped part ( 10 ) engages behind the first piece of finished parquet ( 2 ) between the wall ( 1 ) and the finished parquet. The clamping surface ( 14 ) is preferably rough in order to prevent slipping. The embodiment shown in Fig. 1 is provided with two sawtooth-shaped longitudinal elevations ( 15 ). These can get caught in the groove ( 3 ) of the Ferig parquet, which contributes to the good hold.

The longer leg ( 16 ) of the upper part ( 10 ) is in the rail ( 12 ) by rivets ( 11 ) and side guides ( 17 ), see. Fig. 2, held against rotation. The lateral guides ( 17 ) are held somewhat higher than the rail ( 12 ) and thus lie on the finished parquet ( 2 ), as a result of which the rail ( 12 ) is hollow. If the upper part ( 10 ) is now plastic-coated, the finished parquet surface is protected.

In the embodiment shown, an eye ( 18 ) with thread ( 19 ) for a spindle ( 20 ) is provided above the L-shaped part (see FIG. 3). The spindle ( 20 ) is provided with a conventional handle ( 21 ) and a conventional pressure plate ( 22 ). It can be used to set the distance to the wall ( 1 ). The height of the pressure plate ( 22 ) is designed so that pressure points created by it are below the pressure plate.

In Fig. 2, an additional clamping surface ( 24 ) can be seen, also provided with 2 sawtooth-shaped elevations, in order to be able to set the screw clamp used, designated as a whole with ( 50 ) (see FIG. 4), upright when the toggle ( 55 ) of the slide bracket ( 51 ) is too cumbersome to operate. Fig. 3 shows the top ( 10 ) in plan view. The long side supports ( 25 ) shown here prevent tipping if the upper part ( 10 ) without rail ( 12 ) is used for lateral support.

Fig. 4 shows the screw clamp ( 50 ) together with two finished parquet pieces ( 2 , 2 ') in the tensioned state. After the third parquet row has been tensioned, the sliding bracket ( 51 ) is released and pushed over the third parquet piece. The screw clamp remains in place when the following rows of finished parquet are laid. This keeps the exact distance from the wall, even if heavy knocking is required when laying out further rows of parquet. In Fig. 4 the upper part ( 10 ) is shown on the right side without the rail as a spacer.

Fig. 5 shows a design for supporting thinner laminate, which prevents the same from lifting. With the hand screw ( 60 ) the U-bracket ( 61 ) is adjusted beyond the rail ( 12 ) to keep the laminate surface below. The compression spring ( 62 ) returns the U-bracket ( 61 ) when it turns back ( 60 ) to its starting position, as is required for thicker finished parquet.
