Disclosed is an auxiliary device (1) for alignment of floor boards (2) when laying plank flooring. The auxiliary device is a tensioning unit (10) with two floor-side, protruding, lower contact jaws (12, 14) for resting against board side edges. The contact jaws are joined together via a displacement guide (16) for changing of their mutual internal distance (X1, X2), and with an upper lever mechanism (18) positioned opposite the lower, floor-side contact jaws (12, 14). The lever mechanism (18) is designed according to the toggle principle and is connected to the contact jaws (12, 14) such that by pivoting of the lever mechanism (18) the contact jaws (12, 14) can be moved from a starting position with a larger distance (X1) into a tensioned position with a smaller, defined distance (X2).

1. An auxiliary device for alignment of floor boards on a floor when laying plank flooring, the auxiliary device being a tensioning unit comprising: a first floor-side, protruding, lower contact jaw and a second floor-side, protruding, lower contact jaw, the first contact jaw and the second contact
1. An auxiliary device for alignment of floor boards on a floor when laying plank flooring, the auxiliary device being a tensioning unit comprising: a first floor-side, protruding, lower contact jaw and a second floor-side, protruding, lower contact jaw, the first contact jaw and the second contact jaws being configured for resting against board side edges,a displacement guide connecting the first and second contact jaws, the displacement guide being configured for varying the distance between the first contact jaw and the second contact jaw, the displacement guide consisting of first and second guide parts connected to a respective one of the first and second contact jaws and connected to each other in a telescoping, length-displaceable manner,an upper lever mechanism positioned longitudinally between the first and second contact jaws, the lever mechanism being configured to operate according to a toggle principle and being connected to the first and second contact jaws such that by pivoting of the lever mechanism, the first and second contact jaws are moved from a starting position with a first jaw distance from each other into a tensioned position with a second, defined jaw distance from each other, the first jaw distance being greater than the defined jaw distance,adjusting means for adjusting of the defined jaw distance of the contact jaws in the tensioned position, the adjusting means including a fine adjustment means for varying a length of a pull lever via a screw connection and a stepped rough adjustment means,wherein the pull lever has an eyelet-like hoop element at a free end, the hoop element configured to be detachably suspended in a receptacle connected to the second guide part so that the hoop element is rotatable for fine adjustment of the screw connection in a detached state and wherein for rough adjustment, the first contact jaw connected to the first guide part is configured to be connected to the first guide part via a retaining part and to be locked in different positions for a rough adjustment of the defined jaw distance. 2. The auxiliary device according to claim 1, wherein the defined jaw distance in the tensioned position corresponds to twice the width of selected floor boards plus the width of a joint spacing. 3. The auxiliary device according to claim 1, further comprising that the lever mechanism has a dead point that prevents the lever mechanism from pivoting from the tensioned position to the starting position without applying an external force. 4. The auxiliary device according to claim 1, wherein the lever mechanism comprises a manually pivoting hand lever and the pull lever, the hand lever being connected in an articulated manner to the first guide part via an end-side, first pivot joint, and the pull lever being connected in an articulated manner to the hand lever at a defined joint distance from the first pivot joint via a second pivot joint, the pull lever being configured to be connected to the second guide part at a pull lever end positioned opposite the second pivot joint via the eyelet-like hoop element. 5. The auxiliary device according to claim 4, wherein the pull lever has a free end with an eyelet-like hoop element which can be detachably suspended in a receptacle connected to the second guide part. 6. The auxiliary device according to claim 4, wherein the first pivot joint for the hand lever is attached to a bearing console connected to the first guide part. 7. The auxiliary device according to claim 4, wherein in the tensioned position, the pull lever has a longitudinal axis extending parallel to an axis of displacement of the displacement guide. 8. The auxiliary device according to claim 1, wherein the guide parts of the displacement guide are telescoping hollow profiles engaging into each other. 9. The auxiliary device according to claim 8, wherein the guide parts are tubes with a rectangular cross-section. 10. The auxiliary device according to claim 1, wherein the first contact jaw is locked in the first guide part via a screw connection guided through transverse holes of the retaining part and of the first guide part.
