In detail, the cross section is the Guide rails 3 each from a lower, substantially rectangular Section 3 'formed, the device 1 with its longer when in use Cross-sectional sides in the horizontal or essentially in the horizontal direction, i.e. is arranged in the axial direction in which the two guide rails 3 are offset from one another, and which forms the lower support of the device 1.

At the top is in the middle of section 3 'after section 3' Section 3 '' protruding above. The two guide rails 3 are on the ends firmly connected by a cross piece 4. The latter are each formed from a length of a flat material.

On the guide 2, a knife carriage 5 can be moved in the longitudinal direction of the guide guided. This knife carriage 5, which is freely placed on the guide 2 and by this can also be removed freely, consists of two side panels Carriages 6, each arranged by a cuboid and upright Housing 7 are formed, in such a way that one of the longer peripheral sides of the Housing 7 the top and one of the longer peripheral sides of the housing 7 the Form the underside of the carriage in question. At the bottom of each Carriage 6, a guide groove 8 is provided in the relevant housing 7, which for Bottom of the case as well as the two shorter ones, the front and back of the carriage 6 forming peripheral sides is open and the width is equal to or is at least slightly larger than the width of section 3 '' of the guide rails 3. In each housing 7 rollers 9 about an axis perpendicular to the longitudinal extension of the Guide groove 8 is freely rotatable, in such a way that these rollers with a Part of their circumference in the respective guide groove 8 in the area of the top the bottom of this guide groove protrude so that the carriage 6 itself the two rollers 9 on the top of the respective guide groove 8th Support section 3 '' of the relevant guide rail. in the In the simplest case, the rollers 9 are formed by ball bearings.

The two carriages 6 are connected to one another via a rigid shaft 10. At the illustrated embodiment, the shaft 10 is in the middle of the Carriages 6. The shaft 10 extends in an axial direction perpendicular to Middle plane M of the knife carriage 5.

In FIG. 2, M denotes a center plane of the knife carriage 5. This Center plane M lies parallel to the longitudinal extent of the two guide grooves 8. Furthermore, the two carriages 6 are symmetrical to this central plane M and arranged on both sides of this central plane.

On the shaft 10, a knife holder 11 is pivotally provided. This Knife holder 11 in the embodiment shown consists of two parts 11 ' and 11 '', of which the part 11 'with one over the top of the knife carriage 5th projecting handle 12 is provided. The parting plane between parts 11 'and 11' ' is the central plane M. The two parts 11 'and 11' 'can be connected and braced against each other. At least in one Part, for example in part 11 'are at the parting plane of the knife holder 11 or two oblique grooves 14 are provided on the central plane M. The two parts 11 'and 11' 'of the knife holder 11 are each in the form of rectangular plates executed with their plate sides parallel to the median plane M and with their longer circumferential sides in a starting position or neutral position located knife holder 11 parallel or approximately parallel to the longer sides the housing 7 of the carriages 6 lie.

The grooves 14 are formed so that they are each from the center of the top of the Part 11 'obliquely towards one of the two lower corners of this part run and are also open at both ends. The grooves 14 are used for Inclusion of cutting blades 15, such as those from papering knives are known. After arranging a cutting blade 15 in a groove 14 and after connecting the two parts 11 'and 11' ', the cutting blades 15 by clamping between the two parts 11 'and 11' 'in the knife holder 11 held such that each cutting blade with a corner and the cutting edge there protrudes over a lower corner of the knife receptacle 11. On the shaft 10 is the Knife receptacle 11 pivotally arranged, in such a way that in the neutral Position the knife holder 11 and the cutting provided on this Cutting blades 15 at a sufficiently large distance above the plane E Bottom of the guide 3 are arranged and from this neutral position in working or Cutting positions can be pivoted, in each of which one of the cutting blades 15 protrudes downward from level E.

It goes without saying that when the knife carriage 5 is placed on the guide 3 a Carriage 6 is guided on a guide rail 3.

On the guide 3, a carriage 16 is also slidably guided, which is also the has two carriages 6, but on the top by a support or Platen 17 are connected to each other. On the carriage 16 can be support the user with one knee, which not only fixes the device, but also a more comfortable work is possible.

Various auxiliary devices can be releasably attached to the cross pieces 4 are, for example, stop rails or stop bars 18 or that in the figure 4 again shown in detail additional device 19, which in essentially from a first, angled at one end rail 20 and a second rail 21 angled at both ends.

In the simplest case, the device 1 is used when laying a floor covering, for example when laying a carpet to cut the Floor covering, for example used for cutting to length. In this case it is on at least one end of the guide 3, the stop rail 18 provided as Serves against an edge of the flooring and with which it is then possible Align guide 3 perpendicular to this flooring edge. If this is done, then with the help of the knife carriage 5 moved along the guide 3, an exact cut be carried out, perpendicular to the edge of the flooring. For the cut the knife receptacle 11 pivoted from the neutral position so that when Move the knife carriage 5 lagging side of the knife holder into the Cutting position is pivoted.

The device 1 also enables the floor covering 22 to be so cut that two abutting sections of the flooring Connect seamlessly or essentially seamlessly to one another. For this, the Sections 22 'and 22' 'of the floor covering in the manner shown in FIG. 2 the blank arranged so that they overlap each other. With the knife sledge then both parts 22 'and 22' 'are cut with a single cut, so that after cutting the two parts 22 'and 22' 'without gaps or almost connect seamlessly to each other.

Using the angle rails 20, one on each Cross piece 4 is provided adjustable in the longitudinal direction, it is possible to use the device 1 with these angle rails 20 as stops to position exactly for example to cut strips. Using the second angle rail 21, it is also possible, as shown in FIG. 6, two adjoining parts 22 'and 22' 'of the floor covering so that after cutting between the two parts, an exact joint remains, such as this is the case, for example, with connections for linoleum coverings.

In the described embodiment, the guide 2 with the guide rails 3 and the cross section 4 and preferably also the stop rail 18 and the Rails 20 and 21 made of steel, while the carriages 6 of the knife carriage 5 and of the auxiliary slide 16 and also the knife holder 11 and the support plate 17 Aluminum or an aluminum alloy are made. Of course you can other materials are also used.

FIGS. 7 and 8 show an additional device 19a as a further possible embodiment for use in device 1 or the use of this additional device when cutting a floor covering on joint.

The edge 23 is angled so that it is on a long side of the plate 24th protrudes at right angles above the top of this plate. The plate 24 extends below the lower edge of the angle rail 20. Furthermore, the arrangement is made so that between the top of the plate 24 and the lower edge 20 'of Angle rail 20 remains a slot 25, the height of which is at least equal to the thickness of the respective floor covering 22. At the opposite of the bend 23 An edge 26 of the plate 24 is provided, which extends over the underside of the Plate 24 protrudes. In use, the additional device 19a is together with the Device 1 used in such a way that when the guide is attached to the angle rail 20 2 the plate 24 with its underside on the top of the one floor covering section 22 '' rests and the bend 26 rests against the edge of this section and thereby the device 1 is adjusted relative to the floor covering section 22 ″, while the other floor covering section 22 'to be cut is on top of the Plate 24 rests and if necessary protrudes through slot 25 over guide 2. The Setting is then made so that the respective knife and thus the Cutting plane 27 laterally from the edge of the plate having the bend 26 24, i.e. at a certain distance from this edge of the plate 24, so that after the floor covering section 22 'has been cut between these sections 22' and 22 ″ remains a joint which is equal to the material thickness of the bend 26 plus the distance of the cutting plane 25 from this bend.

The slot 25 makes it possible to have longer tracks of the respective floor covering 22 to cut in sections.

It was assumed above that the plate 24 with its bend 23 the angled end of the angle rail 20 is attached. Basically there is also the possibility of integrating the additional device 19a from a suitable one Flat material, for example made of sheet steel by stamping and bending.

FIG. 9 shows a further possible embodiment of a device 1a which is used for Cutting smaller cuts of floor coverings, for example tiles serves.

The device 1 a essentially consists of a rectangular top view or square cutting plate 30, which has its underside on a base, For example, a floor or work table can be parked. At the A guide 2a is provided on the top of the plate 30, which in turn consists of two there are rectilinear, spaced and parallel guide rails 3a, whose profile corresponds to the profile of the guide rails 3. The guide 2a is like this provided that they are parallel to the two longer sides with their longitudinal extent 31 of the rectangular plate 30 is arranged, in the middle between the Pages 31. At one end, i.e. in the representation chosen for the figure 9 on the The upper end of the guide 2 in the area of the side 32 there is parallel about an axis attached to this side pivotably on a bearing 33, so that at Guide 2a pivoted above a tile 22a to be cut onto plate 30 placed and then the guide 2a can be folded onto this tile 22a.
