Definitions
- This invention relates to a carpet laying tool, especially for laying floor coverings for bath rooms, kitchens and the like.
- Moisture and moisture related damages in real estate properties constitute major issues for property owners, tenants and for insurance companies among others. Negligence in construction or maintenance or for that matter even proper use of inferior construction methods can cause damages that are not limited to surface layers. Moreover, as the damages may spread they may persist despite replacement of the components that caused the damage in the first place. Given sufficient time there may be severe structural damages caused by moisture. There is also a health issue, since moisture may lead to mildew etc.
- a moisture proof barrier such as a floor covering in a carpet like moisture proof material.
- floor covering and carpet should be considered interchangeable terms and both understood as adapted for use in bath rooms, kitchens and the like, by being moisture proof.
- a floor covering may for example constitute the surface layer, similar to a wall to wall carpet or linoleum, or alternatively the floor covering may constitute a moisture proof barrier underneath tiles that constitute the surface layer.
- GVK's trade rules state for example that a wet room floor covering should be fitted and folded to extend 100 mm onto each wall if the rest of the wall is covered in a surface layer similar to the floor covering material.
- the fold and joints in the corners of the floor covering provide challenges in carpeting wet room floor covers.
- One issue is related to thermal movement of joints and floor covering, both the fuse and the floor covering may expand and contract, both during the joining operation but also in the long term. Joints may be prone to weaken if improperly fused and there is often a growth of organic matter in joints that have rough surfaces.
- a carpet laying tool adapted for laying floor coverings for bath rooms, kitchens and the like, the carpet laying tool comprising:
- the carpet laying tool further comprising at least a first triangular guiding portion comprising a planar surface, arranged perpendicularly to the first portion and extending from the base corner along the first edge of the first portion, and the at least a first triangular guiding portion comprising a substantially right angle which is comprised in the base corner.
- the at least a first triangular guiding portion further comprises a hypotenuse edge which is arranged at a predetermined angle to the planar surface of the first portion. The hypotenuse edge is adapted to provide a carpet seam cutting guide for a cutting tool.
- a planar surface should be understood as a side of a portion which is planar, a portion may for example be formed by a metal sheet on which there are two planar surfaces, wherein reference is made to the outward side planar surface.
- the outward sides formed by the first portion and the at least a first triangular guiding portion of the carpet laying tool are preferably planar as this advantageously provides a larger area for distributing pressure when pressing the carpet laying tool onto the wall and provides a larger area for a stable resting support onto the floor.
- the terms "outside”, or “outward side” may consequently be understood as the side facing the wall or the floor.
- An essentially triangular form of the carpet seam cutting guide allows a cut to or from the inner corner of the wet room.
- the perpendicular arrangement of the portions of the carpet laying tool allows a more quickly and steadily usable carpet seam cutting guide than for example a ruler or a dreieck-ruler.
- the carpet laying tool may be formed so that a corner seam fulfills requirements such as GVK's trade rules, which indicate that a seam should be cut diagonally at substantially 45° to the floor.
- first edge tangent and the second edge tangent should be understood as tangents to the first edge and to the second edge, respectively. Consequently, even if the first edge and/or the second edge may be slightly curved adjacent to the base corner, the tangents to a majority of points along the first edge intersect with the tangents to a majority of points along the second edge at a substantially right angle.
- planar surface, the first and the second edge may each, respectively, be used to rest the carpet laying tool on or against a bedding, such as on a floor or against a wall.
- the guiding portion is triangular in the sense that the planar surface of the portion may be essentially triangular in form.
- the substantially right angle is preferably within tolerances of 90° in the plane of the planar surface of the at least a first triangular guiding portion.
- either edge of the at least a first triangular guiding portion intersecting in the right angle may have concave portions and still allow the carpet laying tool to rest on a bedding.
- the portion is triangular in that there is a hypotenuse edge arranged obliquely to the right angle in the plane of the planar surface of the at least a first triangular guiding portion.
- the at least a first triangular guiding portion may alternatively be truncated, for example at any corner distal from the right angle.
- either portion of the carpet laying tool may be perforated, milled or material may be removed from any planar surface or along any edge, for example to provide a lighter and/or more resource efficient tool.
- the hypotenuse edge may preferably be kept continuous and any portion of the planar surface which will cover a seam when the carpet laying tool is pressed against a corner in the wet room is advantageously not milled or perforated.
- the first portion may be a fold cutting guide portion wherein at least one of the first edge and the second edge of the fold cutting guide portion may extend from the base corner and at least to a first fold cutting guide arranged perpendicularly to the at least one of the first edge and the second edge.
- the first fold cutting guide may advantageously be adapted for supporting a cutting tool at a predetermined distance from the respective other edge of the at least one of the first edge and the second edge. Such that the cutting tool is rested the predetermined distance from a bedding on which the carpet laying tool is rested when in use.
- the first fold cutting guide should be understood as a guiding template or a guiding support adapted for allowing a user to make a cut parallel with a bedding along which the carpet laying tool is moved, wherein the first fold cutting guide continuously guides the cutting tool at a predetermined distance from the bedding.
- the first fold cutting guide is substantially parallel with the respective edge which it is not arranged adjacent to, this may be understood as the other edge of the at least one of the first edge and the second edge. Either edge may be provided with a first fold cutting guide.
- the at least one of the first and the second edge may extend a distance from the base corner equal to the predetermined distance from the respective other edge of the at least one of the first edge and the second edge, i.e. where the first fold cutting guide is arranged.
- the at least one of the first and the second edge may extend beyond the location of the first fold cutting guide.
- the predetermined distance of the first fold cutting guide to the respective other edge of the at least one of the first edge and the second edge may be chosen from a group comprising of 10 cm and 13 cm.
- the first portion may be a second triangular guiding portion.
- the second triangular guiding portion comprising a substantially right angle which is comprised in the base corner, and comprising a hypotenuse edge arranged at a predetermined angle to the planar surface of the at least a first triangular guiding portion, wherein the hypotenuse edge is adapted to provide a carpet seam cutting guide for a cutting tool.
- the second triangular guiding portion may be symmetrically mirrored to the at least a first triangular guiding portion on the first edge of the carpet laying tool. Furthermore, a carpet laying tool provided with the second triangular guiding portion may allow the user to cut a seam on either wall comprised in a corner.
- the first fold cutting guide may form an outer edge on the fold cutting guide portion, adapted for supporting a cutting tool parallel to the respective other edge of the at least one of the first edge and the second edge.
- the cutting tool may be advantageously be supported parallel to a bedding on which the carpet laying tool is rested when in use.
- the first and/or the second edge of the fold cutting guide portion may, respectively, extend the predetermined distance from the base corner to a right angled corner where the first fold cutting guide may form a first fold cutting guide edge.
- first and/or the second edge of the fold cutting guide portion may, respectively, extend further or shorter than the predetermined distance from the base corner to a corner where a step-shaped edge may be formed, wherein one of the steps is at the predetermined parallel distance from the respective other edge of the at least one of the first edge and the second edge.
- the first fold cutting guide comprises at least one longitudinal slit in the planar surface of the fold cutting guide portion, wherein the at least one longitudinal slit is adapted for receiving a cutting edge tool parallel to the respective other edge of the at least one of the first edge and the second edge.
- the cutting tool may therefore be supported parallel to a bedding on which the carpet laying tool is rested when in use.
- the first fold cutting guide may be a slit through the planar surfaces of the fold cutting guide portion adjacent to one of the edges.
- the at least one slit extends longitudinally from the respective adjacent edge, and that the slit is a through hole through which a cutting tool such as a knife may protrude.
- the longitudinal extension may be at least so long that a cutting tool protrudes sufficiently through to be able to cut through a thickness of a floor covering against which the tool may be pressed.
- the longitudinal slit may advantageously guide the cutting tool when in use.
- the longitudinal slit may provide both horizontal and vertical support to the cutting tool when in use.
- the fold cutting guide portion may further comprise a second fold cutting guide, wherein the second fold cutting guide is arranged perpendicularly to at least one of the first edge and the second edge of the fold cutting guide portion.
- the second fold cutting guide may be adapted for supporting a cutting tool at a different distance from the respective other edge of the at least one of the first edge and the second edge compared to the predetermined distance of the first fold cutting guide. This may provide the advantage that the user may use the same carpet laying tool to cut either predetermined height of the carpet fold on the wall.
- the second fold cutting guide may be an outer edge on the fold cutting guide portion, adapted for supporting a cutting tool parallel to the respective other edge of the at least one of the first edge and the second edge.
- the second fold cutting guide comprises at least one longitudinal slit in the planar surface of the fold cutting guide portion, wherein the at least one longitudinal slit may be adapted for receiving a cutting edge tool parallel to the respective other edge of the at least one of the first edge and the second edge.
- the second fold cutting guide comprises at least two aligned longitudinal slits in the planar surface of the fold cutting guide portion, wherein the at least two aligned longitudinal slits may be of different dimension, adapted for receiving different cutting tools.
- the carpet laying tool further comprises a second triangular guiding portion and the second triangular guiding portion comprising a substantially right angle which is comprised in the base corner, and comprising a hypotenuse edge arranged at a second predetermined angle to the planar surface of the at least a first triangular guiding portion.
- the hypotenuse edge is adapted to provide a carpet seam cutting guide for a cutting tool wherein the second triangular guiding portion is comprising a planar surface, extending along the second edge of the fold cutting guide portion and being perpendicular to the at least a first triangular guiding portion and being perpendicular to the fold cutting guide portion.
- the first triangular guiding portion, the second triangular guiding portion and the fold cutting guide portion are arranged such that the carpet laying tool forms a tetrahedral shape.

Description
- This invention relates to a carpet laying tool, especially for laying floor coverings for bath rooms, kitchens and the like.
- Moisture and moisture related damages in real estate properties constitute major issues for property owners, tenants and for insurance companies among others. Negligence in construction or maintenance or for that matter even proper use of inferior construction methods can cause damages that are not limited to surface layers. Moreover, as the damages may spread they may persist despite replacement of the components that caused the damage in the first place. Given sufficient time there may be severe structural damages caused by moisture. There is also a health issue, since moisture may lead to mildew etc.
- In particular bathrooms and even kitchens are generally the most affected rooms, due to plumbing and piping being led to and from such rooms. They are often referred to as wet rooms as the risk of damages are significantly higher in wet rooms due to spills, leaks or long term use in for example showers, bath tubs, kitchen sinks or machines such as dish washers or washing machines. The increased risk forms an incentive to push for construction standards and requirements specifically for wet rooms. One such requirement is the trade rules for moisture proof layers in wet rooms issued by GVK, (GVKs Branschregler for tätskikt i våtrum,
issue 4 september 2011). GVK is a foundation in Sweden comprising a union of property owners, property developers, plumbing and HVAC enterprises. However, there may be other similar organizations around the world. While there are different methods for moisture proofing a wet room, one exemplary method of mitigating the risks is to install a moisture proof barrier such as a floor covering in a carpet like moisture proof material. In this context, floor covering and carpet should be considered interchangeable terms and both understood as adapted for use in bath rooms, kitchens and the like, by being moisture proof. Such a floor covering may for example constitute the surface layer, similar to a wall to wall carpet or linoleum, or alternatively the floor covering may constitute a moisture proof barrier underneath tiles that constitute the surface layer. GVK's trade rules state for example that a wet room floor covering should be fitted and folded to extend 100 mm onto each wall if the rest of the wall is covered in a surface layer similar to the floor covering material. If the surface layer of the wall is ceramic tiles, the floor covering should extend 130 mm onto each wall. Furthermore, any joints on the walls should be offset more than 100 mm from corners, the fold of the floor covering being exempt. The GVK trade rules indicate that joints in the corners of floor coverings should be placed diagonally from the intersection of the walls and the floor, and run diagonally to end more than 100 mm from the corner of the wall. - The fold and joints in the corners of the floor covering provide challenges in carpeting wet room floor covers. To fit the floor covering to extend 100 mm or 130 mm onto the walls a seam has to be cut in each corner and the floor covering and any joints have to provide a continuous moisture proof barrier, achieved for example by heat fusing the joints. One issue is related to thermal movement of joints and floor covering, both the fuse and the floor covering may expand and contract, both during the joining operation but also in the long term. Joints may be prone to weaken if improperly fused and there is often a growth of organic matter in joints that have rough surfaces.
- One tool which is said to improve joints on wall to wall carpets is described in
US 4,699,686 . The tool therein described is said to reduce the risk of misalignment and discoloration by cooling down joints. However, there is still a need for a tool which allows simplified laying of floor coverings in wet rooms. - An object of the present invention is to at least partly alleviate the above-discussed drawbacks of the prior art. The invention is based on the insight that by having a tool which can be used on the fold onto the wall when fitting a wet room floor covering, particularly in the corners at least inner corners may be more easily and quickly fitted according to guidelines. Furthermore, joints may be given a finish that may be more resistant to organic growth and corners may be fitted so that effects of thermal expansion and contraction are reduced.
- According to a first aspect of the invention this may be achieved with a carpet laying tool adapted for laying floor coverings for bath rooms, kitchens and the like, the carpet laying tool comprising:
- a first portion comprising a planar surface and a first and a second edge which are each substantially straight, the first and the second edge being arranged with a first edge tangent intersecting a second edge tangent at a right angle at a base corner of the carpet laying tool.
- The carpet laying tool further comprising at least a first triangular guiding portion comprising a planar surface, arranged perpendicularly to the first portion and extending from the base corner along the first edge of the first portion, and the at least a first triangular guiding portion comprising a substantially right angle which is comprised in the base corner. The at least a first triangular guiding portion further comprises a hypotenuse edge which is arranged at a predetermined angle to the planar surface of the first portion. The hypotenuse edge is adapted to provide a carpet seam cutting guide for a cutting tool.
- In the context of the invention a planar surface should be understood as a side of a portion which is planar, a portion may for example be formed by a metal sheet on which there are two planar surfaces, wherein reference is made to the outward side planar surface. The outward sides formed by the first portion and the at least a first triangular guiding portion of the carpet laying tool are preferably planar as this advantageously provides a larger area for distributing pressure when pressing the carpet laying tool onto the wall and provides a larger area for a stable resting support onto the floor. The terms "outside", or "outward side" may consequently be understood as the side facing the wall or the floor.
- An essentially triangular form of the carpet seam cutting guide allows a cut to or from the inner corner of the wet room. The perpendicular arrangement of the portions of the carpet laying tool allows a more quickly and steadily usable carpet seam cutting guide than for example a ruler or a dreieck-ruler. The carpet laying tool may be formed so that a corner seam fulfills requirements such as GVK's trade rules, which indicate that a seam should be cut diagonally at substantially 45° to the floor.
- Furthermore, the carpet laying tool may be used to press against the corner and at least part of the seam of the carpet while a fused joint is cooling down. This allows smoother joints and corners which are less likely to release from the wall and/or floor surface due to thermal contraction.
- In the context of the invention carpet and carpet laying tool refers to floor coverings for use in bath rooms, kitchens and the like, and to a tool for use with such floor coverings. While common textile wall to wall carpets should not be considered excluded, there is usually no need for covering parts of the wall with textile wall to wall carpets. Neither do the joints of textile wall to wall carpets need to fulfill the same requirements under inspection.
- Furthermore in the context of the invention, the first edge tangent and the second edge tangent should be understood as tangents to the first edge and to the second edge, respectively. Consequently, even if the first edge and/or the second edge may be slightly curved adjacent to the base corner, the tangents to a majority of points along the first edge intersect with the tangents to a majority of points along the second edge at a substantially right angle.
- There may, for example, be a curvature at an end of either edge or there may be a portion of either edge which may be concave. In use, the planar surface, the first and the second edge may each, respectively, be used to rest the carpet laying tool on or against a bedding, such as on a floor or against a wall.
- The guiding portion is triangular in the sense that the planar surface of the portion may be essentially triangular in form. Analogously to the right angle of the first portion the substantially right angle is preferably within tolerances of 90° in the plane of the planar surface of the at least a first triangular guiding portion. However, either edge of the at least a first triangular guiding portion intersecting in the right angle may have concave portions and still allow the carpet laying tool to rest on a bedding. Furthermore, the portion is triangular in that there is a hypotenuse edge arranged obliquely to the right angle in the plane of the planar surface of the at least a first triangular guiding portion.
- The at least a first triangular guiding portion may alternatively be truncated, for example at any corner distal from the right angle. Similarly, either portion of the carpet laying tool may be perforated, milled or material may be removed from any planar surface or along any edge, for example to provide a lighter and/or more resource efficient tool. However, the hypotenuse edge may preferably be kept continuous and any portion of the planar surface which will cover a seam when the carpet laying tool is pressed against a corner in the wet room is advantageously not milled or perforated.
- According to an exemplary embodiment the first portion may be a fold cutting guide portion wherein at least one of the first edge and the second edge of the fold cutting guide portion may extend from the base corner and at least to a first fold cutting guide arranged perpendicularly to the at least one of the first edge and the second edge. The first fold cutting guide may advantageously be adapted for supporting a cutting tool at a predetermined distance from the respective other edge of the at least one of the first edge and the second edge. Such that the cutting tool is rested the predetermined distance from a bedding on which the carpet laying tool is rested when in use.
- In the context of the invention the first fold cutting guide should be understood as a guiding template or a guiding support adapted for allowing a user to make a cut parallel with a bedding along which the carpet laying tool is moved, wherein the first fold cutting guide continuously guides the cutting tool at a predetermined distance from the bedding. In the context of the exemplary embodiment it should be understood that the first fold cutting guide is substantially parallel with the respective edge which it is not arranged adjacent to, this may be understood as the other edge of the at least one of the first edge and the second edge. Either edge may be provided with a first fold cutting guide. Furthermore, it should be noted that the at least one of the first and the second edge may extend a distance from the base corner equal to the predetermined distance from the respective other edge of the at least one of the first edge and the second edge, i.e. where the first fold cutting guide is arranged. Alternatively, the at least one of the first and the second edge may extend beyond the location of the first fold cutting guide.
- According to an exemplary embodiment the predetermined distance of the first fold cutting guide to the respective other edge of the at least one of the first edge and the second edge may be chosen from a group comprising of 10 cm and 13 cm.
- According to another exemplary embodiment the first portion may be a second triangular guiding portion. The second triangular guiding portion comprising a substantially right angle which is comprised in the base corner, and comprising a hypotenuse edge arranged at a predetermined angle to the planar surface of the at least a first triangular guiding portion, wherein the hypotenuse edge is adapted to provide a carpet seam cutting guide for a cutting tool.
- Any variations and advantages of the at least a first triangular guiding portion described above may analogously be attributed to the second triangular guiding portion. The second triangular guiding portion may be symmetrically mirrored to the at least a first triangular guiding portion on the first edge of the carpet laying tool. Furthermore, a carpet laying tool provided with the second triangular guiding portion may allow the user to cut a seam on either wall comprised in a corner.
- According to one exemplary embodiment the hypotenuse edge may advantageously be arranged at a predetermined angle to the planar surface within a range of 40°-50°, or within a range of 42°-48°, or within a range of 44°-46°. Such that the predetermined angle of the at least a first triangular guiding portion and/or the second predetermined angle is within a range of 40°-50°, or within a range of 42°-48°, or within a range of 44°-46°. In the context of the invention the predetermined angle may be measured to the planar surface of an adjacent portion to the portion on which the hypotenuse edge is arranged, e.g. the planar surface of the first portion for the hypotenuse edge of the at least a first triangular guiding portion.
- According to an exemplary embodiment the first fold cutting guide may form an outer edge on the fold cutting guide portion, adapted for supporting a cutting tool parallel to the respective other edge of the at least one of the first edge and the second edge. The cutting tool may be advantageously be supported parallel to a bedding on which the carpet laying tool is rested when in use. With other words the first and/or the second edge of the fold cutting guide portion may, respectively, extend the predetermined distance from the base corner to a right angled corner where the first fold cutting guide may form a first fold cutting guide edge.
- In the context of the invention it should be understood that the first fold cutting guide provides supports so that a user may rest a blade of the cutting tool on the first fold cutting guide edge, such that a continuous cut, parallel to the floor, can be made in the fold of the carpet, which will be further explained.
- Alternatively, according to another exemplary embodiment the first and/or the second edge of the fold cutting guide portion may, respectively, extend further or shorter than the predetermined distance from the base corner to a corner where a step-shaped edge may be formed, wherein one of the steps is at the predetermined parallel distance from the respective other edge of the at least one of the first edge and the second edge.
- According to an exemplary embodiment the first fold cutting guide comprises at least one longitudinal slit in the planar surface of the fold cutting guide portion, wherein the at least one longitudinal slit is adapted for receiving a cutting edge tool parallel to the respective other edge of the at least one of the first edge and the second edge. The cutting tool may therefore be supported parallel to a bedding on which the carpet laying tool is rested when in use.
- The first fold cutting guide may be a slit through the planar surfaces of the fold cutting guide portion adjacent to one of the edges.
- In the context of the invention it should be understood that the at least one slit extends longitudinally from the respective adjacent edge, and that the slit is a through hole through which a cutting tool such as a knife may protrude. The longitudinal extension may be at least so long that a cutting tool protrudes sufficiently through to be able to cut through a thickness of a floor covering against which the tool may be pressed.
- The longitudinal slit may advantageously guide the cutting tool when in use. The longitudinal slit may provide both horizontal and vertical support to the cutting tool when in use.
- According to an exemplary embodiment the first fold cutting guide may comprise at least two aligned longitudinal slits in the planar surface of the fold cutting guide portion, wherein the at least two aligned longitudinal slits may be of different dimension, adapted for receiving different cutting tools.
- According to another exemplary embodiment the fold cutting guide portion may further comprise a second fold cutting guide, wherein the second fold cutting guide is arranged perpendicularly to at least one of the first edge and the second edge of the fold cutting guide portion. The second fold cutting guide may be adapted for supporting a cutting tool at a different distance from the respective other edge of the at least one of the first edge and the second edge compared to the predetermined distance of the first fold cutting guide. This may provide the advantage that the user may use the same carpet laying tool to cut either predetermined height of the carpet fold on the wall.
- According to an exemplary embodiment the predetermined distance of the second fold cutting guide to the respective other edge of the at least one of the first edge and the second edge is chosen from a group comprising of 10 cm and 13 cm, wherein the distance may advantageously be different from the predetermined distance chosen for the first fold cutting guide.
- In the context of the invention it should be understood that 10 cm and 13 cm are wall fold heights which fulfill requirements of the GVK's trade rules, and as such the group of selectable predetermined distances may change to fulfill requirements should the requirements change. Additionally, there may be markets where other requirements are in use, wherein the group of selectable predetermined distances may be analogously changed.
- According to an exemplary embodiment the first fold cutting guide is arranged adjacent to the first edge and perpendicularly to the first edge and parallel to the second edge, and wherein the second fold cutting guide is arranged adjacent to the second edge and perpendicularly to the second edge and parallel to the first edge. This may allow the user to distinguishably use one edge to rest on the floor when the requirements state a first of the predetermined heights, and the other edge may be used when the requirements state a second of the predetermined heights.
- According to an exemplary embodiment the second fold cutting guide may be an outer edge on the fold cutting guide portion, adapted for supporting a cutting tool parallel to the respective other edge of the at least one of the first edge and the second edge.
- According to another exemplary embodiment the second fold cutting guide comprises at least one longitudinal slit in the planar surface of the fold cutting guide portion, wherein the at least one longitudinal slit may be adapted for receiving a cutting edge tool parallel to the respective other edge of the at least one of the first edge and the second edge.
- According to an exemplary embodiment the second fold cutting guide comprises at least two aligned longitudinal slits in the planar surface of the fold cutting guide portion, wherein the at least two aligned longitudinal slits may be of different dimension, adapted for receiving different cutting tools.
- According to an exemplary embodiment the carpet laying tool further comprises a second triangular guiding portion and the second triangular guiding portion comprising a substantially right angle which is comprised in the base corner, and comprising a hypotenuse edge arranged at a second predetermined angle to the planar surface of the at least a first triangular guiding portion. The hypotenuse edge is adapted to provide a carpet seam cutting guide for a cutting tool wherein the second triangular guiding portion is comprising a planar surface, extending along the second edge of the fold cutting guide portion and being perpendicular to the at least a first triangular guiding portion and being perpendicular to the fold cutting guide portion. The first triangular guiding portion, the second triangular guiding portion and the fold cutting guide portion are arranged such that the carpet laying tool forms a tetrahedral shape.
- According to an exemplary embodiment the carpet laying tool may further comprise a third portion. The third portion comprising a planar surface, extending along the second edge of the first portion and being perpendicular to the at least a first triangular guiding portion and perpendicular to the first portion, and comprising a substantially right angle which is comprised in the base corner, the portions being arranged such that the carpet laying tool forms a tetrahedral shape.
- A carpet laying tool having a tetrahedral shape may advantageously allow the user to cut a diagonal cut from the corner to either wall comprised in the respective corner. Furthermore, the tetrahedral tool with a fold cutting guide portion may allow the user to steadily cut the fold on the wall while using the same tool as used for cutting the seam and pressing the seam.
- According to an exemplary embodiment the base corner may comprise the right angles of a first portion and a triangular guiding portion, and further comprise the right angle of a flange which is perpendicular to the first portion and to the triangular guiding portion.
- According to an exemplary embodiment the base corner may be rounded on at least one side. The base corner may advantageously be rounded at least on the outside. A base corner rounded on the outside allows the user to more evenly distribute heated material of a fuse in the corner of the wet room when the base corner is arranged in the corner where the walls and the floor meet. Furthermore, a rounded base corner decreases a risk of piercing the fuse or the risk of producing a rougher corner of the fuse. It has been realized that there is a higher risk of growth of organic matter with a fuse which is rougher or not as well distributed.
- According to an exemplary embodiment the carpet laying tool may further comprise a handle. The handle may be arranged such that a grip is provided which is oblique to the base corner.
- The handle may allow a user to more easily press the carpet laying tool against the floor covering or carpet.
- According to an exemplary embodiment the carpet laying tool may further comprise a thermally conducting material. A thermally conducting material may allow a quicker cool down of joints against which the carpet laying tool is pressed.

Fig 1 a shows acarpet laying tool 1 according to one embodiment of the invention, the carpet laying tool may in short be referred to as thetool 1. The tool is adapted for performing three steps of laying a carpet like floor covering in a bathroom, kitchen or the like. As the floor covering needs to be folded and fastened onto the wall to provide moisture protection the tool may be used for cutting a diagonal seam in a corner of a room. The tool may further be used to press and cool a seam which is being fused. Furthermore, the tool may be used for cutting the floor covering horizontally along the wall, so that the cut is at an even height from the floor all around the room. - The illustrated
carpet laying tool 1 has a tetrahedral shape formed by three planar portions, afirst portion 3, asecond portion 8 and athird portion 11 here exemplified as three sheets or pieces of a rigid material, such as for example stainless steel. The threeportions Fig. 1 a may be referred to as showing the inside of thetool 1, which is adapted to face the user when thetool 1 is in use, i.e. when one portion of the outside of the tool is arranged on a floor, and another portion is abutting the wall. The view fromFig. 1c shows the outside of the tool. The portions have abutted right angles, forming abase corner 2 similar to a tip of the tetrahedral shape of thetool 1. Any distances disclosed, unless otherwise specified, are made from edges and/or corners on the outside measured along an edge. Furthermore, if, for example, the base corner is rounded the reference point is an outside point where tangents to edges of theportions - The
first portion 3 of the carpet laying tool is illustrated at the lower part of the tool inFig 1 a and from a top view inFig. 1b , which Figs. will be discussed together. Thefirst portion 3 will be referred to as a fold cuttingguide portion 3. The fold cutting guide portion is when in use adapted for being abutted to a wall and provide a support for a cutting tool so that the carpet like floor covering may be cut evenly and parallel with reference to the bedding, i.e. the floor. The fold cuttingguide portion 3 is in this example embodiment shaped like truncated triangle where theright angle 2a (SeeFig. 1 b) is not truncated and is one part of thebase corner 2. The other corners of thefold cutting guide 3 have been truncated 14, 15, resulting in a five-edged fold cuttingguide portion 3. Afirst edge 4 is extending approximately a distance S1 to thetruncation 14 and asecond edge 5 is extending approximately a distance S2 cm to the respective truncation. The distance S1 may for example be 11 cm. The distance S2 may for example be 14 cm. At a distance L1 along the first edge 4 a first fold cutting guide 6 is located, here exemplified with twoslits second edge 5. - The
slits first edge 4, in a direction parallel to thesecond edge 5. Theslits guide portion 3. The twoslits Figs. 5a-5b . Theslit 6a, closest to thefirst edge 4, is in this example embodiment longer in longitudinal extension than thedistal slit 6b, so that cutting tools of different dimension can be received. At a distance L2 along the second edge 5 a secondfold cutting guide 7 is located, here exemplified by twoslits first edge 4. The distances L1 and L2 are in this example embodiment chosen to fulfill requirements of the GVK. The distances S1 and S2 are in this example embodiment more arbitrarily chosen balancing a sufficiently robust tool against an unwieldy tool, such that the tool is also provided with a sufficiently long seam cutting guide and a sufficiently large surface area for covering and cooling carpet joints tool. - The
slits second edge 5, in a direction parallel to thefirst edge 4, and they are perforating the sheet of the fold cuttingguide portion 3. The fold cuttingguide portion 3 has a planar inner surface 3a as shown inFigs. 1 a and 1 b, and a planarouter surface 3b as shown inFig. 1c which illustrates the outside perspective of thetool 1. - With reference to
Fig 1 a thesecond portion 8 may be referred to as atriangular guiding portion 8 arranged perpendicularly to the first portion along thefirst edge 4 of the fold cuttingguide portion 3. Thetriangular guiding portion 8 has a triangular shape with a 90°right angle 2b and two 45° angles, where theright angle 2b is part of thebase corner 2. Consequently, there are two equallylong edges 4, 9. The lower edge coincides with and is comprised in thefirst edge 4 by a connection such as welding, riveting, folding of a larger sheet comprising more than one portion, etc. The lower 45° angled corner α is abutted to the end of thefirst edge 4 at thetruncated edge 14. The other edge 9 of thetriangular guiding portion 8 is extending a distance equal to S1 but perpendicularly from the fold cuttingguide portion 3. With reference to the orientation that is illustrated inFig. 1 a the edge 9 may also be referred to as the vertical edge 9. A third, hypotenuse,edge 10 extends straightly between the two 45° angled corners of the triangular guiding portion. The sheet thickness of the stainless steel triangular guiding portion offers a stable, unbending seam cutting guide for a cutting tool, such as knife, along thehypotenuse edge 10. Thetriangular guiding portion 8 has a planarinner surface 8a shown inFig 1a , and a planarouter surface 8b shown inFig. 1 c which illustrates the outside perspective of thetool 1. - With reference to
Fig 1 a thethird portion 11 may be referred to as a secondtriangular guiding portion 11 arranged perpendicularly to the first portion along thesecond edge 5 of the fold cuttingguide portion 3, and arranged perpendicularly to thesecond portion 8 along the vertical edge 9. The secondtriangular guiding portion 11 is a symmetrically mirrored portion to thetriangular guiding portion 8 connected to the vertical edge 9. A lower edge coincides with and is comprised in a portion of thesecond edge 5 by a connection such as welding, riveting, folding of a larger sheet comprising more than one portion, etc. The portion of thesecond edge 5 along which the secondtriangular guiding portion 11 and the fold cuttingguide portion 3 coincide is approximately equally long as the distance S1. Consequently, thesecond edge 5 extends beyond where ahypotenuse edge 12 of the secondtriangular guiding portion 11 intersects with thesecond edge 5. The secondtriangular guiding portion 11 has a planarinner surface 11 a shown inFig 1 a, and a planarouter surface 11 b shown inFig. 1c which illustrates the outside perspective of thetool 1. - The outside planar surfaces shown in
Fig. 1c provide three supportingsurfaces carpet laying tool 1. When resting thetool 1 on the outsideplanar surface 3b of the fold cuttingguide portion 3 this may provide a support to abut eitheroutside surface triangular guiding portion hypotenuse edge 10 provides a diagonal template abutting a wall, when thefirst edge 4 and theedge 14 placed into a lower corner of a wet room. - The outer
planar surface 11 b of the secondtriangular guiding portion 11 may provide a floor resting support when thefold cutting guide 3 is abutting a wall, such that the fold cutting guide 6 is arranged parallel to the floor at a vertical distance equal to L1. The outerplanar surface 8b of thetriangular guiding portion 8 may provide a floor resting support when thefold cutting guide 3 is abutting a wall, such that thefold cutting guide 7 is arranged parallel to the floor at a vertical distance equal to L2. - However, either
edge guide portion 3 arranged beyond and parallel to the fold cuttingguide slits first edge 4 and thesecond edge 5 of thefold cutting guide 3 could each be provided with two fold cutting guides; A first fold cutting guide in the form of one or more slits at the distance L1 and a second fold cutting guide in the form of en edge at the distance L2 - Either outer

Furthermore, similarly to the fold cuttingguide portion 3 illustrated in theFigs. 1a-1c , a fold cuttingguide portion 203 illustrated inFig. 2 is shaped like a truncated triangle. Afirst edge 204 and asecond edge 205 are extending approximately a distance substantially equal to the distance L1 (or L2, which is also possible) as shown inFig. 1b and they are arranged perpendicularly to each other. At a distance substantially equal to the distance L1 (or L2) on eitheredge guide edges 206 extending longitudinally from either the first 204 or the second 205 edge, respectively. The respective fold cuttingguide edges 206 extend in a direction parallel to theedge guide edge 206 is not extending from. The fold cuttingguide edges 206 here illustrated are one alternative embodiment to the fold cuttingguide slits 6, 7 illustrated inFigs. 1a-1c . Note that as the fold cutting guide edges 206 are at the same distance from thebase corner 202 there is a firstfold cutting guide 206, along both twoedges - While not present in the example embodiment illustrated in
Fig. 2 thetool 201 could for example have been provided with a second fold cutting guide (not shown) in the form of a slit located closer to thebase corner 202 than either of the fold cutting guide edges 206. - The

Fig 3 shows another exemplary embodiment of the carpet laying tool 301, also in short referred to as the tool 301. Thefirst portion 303 of the carpet laying tool 301 will be referred to as a fold cuttingguide portion 303. The fold cuttingguide portion 303 is similarly to the fold cuttingguide portions planar extension 316, extending the fold cuttingguide portion 303 adjacent to a lower 45° angled corner of thetriangular guiding portion 308. With the square planar extension afirst edge 304 is extending a distance approximately equal to the distance L2 inFig. 1b while asecond edge 205 is extending a distance approximately equal to the distance L1 inFig. 1 b. At the distance approximately equal to the distance L2 inFig. 1b , an edge along the squareplanar extension 316, parallel to the second edge 305 a secondfold cutting guide 307 is located in the form of a fold cuttingguide edge 307, i.e. the secondfold cutting guide 307 is part of the squareplanar extension 316. At the distance approximately equal to the distance L1 inFig. 1b along thesecond edge 305, a firstfold cutting guide 306 is located in the form of a fold cuttingguide edge 306. - Referring now to
Fig 4a acarpet laying tool 401 according to an example embodiment of the invention is shown in perspective view. The tetrahedral carpet laying tool is formed by bending one planar sheet or piece of metal. However, the carpet laying tool illustrated inFig. 4a has ahandle 413 formed by the same sheet of metal. Afirst portion 403, such as thefold cutting portion 403, is comprised at one end of the sheet of metal forming thecarpet laying tool 401 illustrated inFig. 4a . The sheet has been bent along the first edge 404, so that the adjacenttriangular guiding portion 408 is perpendicular to the fold cuttingguide portion 403. The sheet is further bent along thevertical edge 409 and a portion of the sheet is bent to form ahandle 413 in the form of an oblique cone with itsbase 413b connected to the fold cuttingguide portion 403 and with itstip 413a connected to thetip 409a of thevertical edge 409. As thehandle 413 is at least partially circularly cone shaped the sheet is folded double onto itself and reconnects with thevertical edge 409. Thehandle 413 is at least partially circularly cone shaped meaning that a cross section parallel to the fold cuttingguide portion 403 would resemble a water-drop shape with a double fold of the sheet toward thevertical edge 409. - Where the sheet reconnects at the
vertical edge 409 it is further bent along thevertical edge 409 to form a secondtriangular guiding portion 411 which is aligned with and perpendicular to the second edge 405 of the fold cuttingguide portion 403. Thecarpet laying tool 401 illustrated inFig. 4a may be connected, for example by welding, gluing or riveting along thevertical edge 409, which has two aligned and adjacent bends, and the second edge 405, such that all edges 404, 409, 405 are seamless. Furthermore, abase edge 402 may be rounded, for example by filling material between the two adjacent bends along thevertical edge 409 and machining, grinding or otherwise forming thebase corner 402 to be rounded. -
Fig 4b shows another embodiment of a carpet laying tool 401'. The carpet laying tool 401' is formed similarly to thecarpet laying tool 401 illustrated inFig. 4a but without the portion of the sheet forming the second triangular guiding portion (consequently not shown inFig. 4b ). The carpet laying tool 401' illustrated here comprises a fold cuttingguide portion 403, atriangular guiding portion 408 and ahandle 413. -
Fig 4c shows another embodiment of acarpet laying tool 401". Thecarpet laying tool 401" is formed similarly to thecarpet laying tool 401 illustrated inFig. 4a but without the portion of the sheet forming the fold cutting guide portion (consequently not shown inFig. 4c ). Thecarpet laying tool 401" illustrated here comprises atriangular guiding portion 408, a secondtriangular guiding portion 411, and ahandle 413, possibly making the tool somewhat more resource efficient to manufacture. - Furthermore, as the
tools 401' and 401" are formed by only twoportions tool 401' or 401" may be provided and be rounded, for example by providing filling material (not shown) between the two adjacent bends along thevertical edge 409 or by providing a flange (not shown), smaller in size than a portion of thetool 401' or 401", and machining, grinding or otherwise forming the base corner (not shown) to be rounded. -
Fig. 5a shows a schematic perspective view of aninner corner 100 in a wet room, the corner is illustrated with two walls B1, B2, and a floor (not shown) intersecting with a wet room carpet/floor covering A arranged on the floor and extending up on the walls. When using a tool such as the embodiment illustrated inFigs.1a-c a user provides and fits a carpet/floor covering A to the wet room so that it is folded up onto a lower portion of each wall, the folded portions of the floor covering A here referred to as wall folds A1, A2. In the corner, at a vertical intersection of the walls a wedge shaped fold D is formed by excess material as the floor covering A is folded onto the two walls B1, B2. The floor covering A is preferably folded onto the wall B1 so that the wedge shaped fold D is placed adjacent to the wall fold A1 such that locally, at the wedge shaped fold, there is three layers of floor covering A abutting the wall B1 at the corner. A portion of the wall fold A1 is preferably sandwiched between the wedge shaped fold D and the wall B1. - Moving on to
Fig. 5b acarpet laying tool 1 as illustrated inFigs. 1a-1c is arranged in the corner of the wet room with the fold cuttingguide portion 3 resting on the floor covering A and with thetriangular guiding portion 8 abutting the wall fold A1 and the wedge shaped fold D. Thehypotenuse edge 10 is placed diagonally from the lower corner of the room and may be aligned with a diagonal edge of the wedge shaped fold D. As illustrated inFig. 5b thehypotenuse edge 10 may thus provide a seam cutting guide for a cutting tool such as a knife C, so that the wedge shaped fold D and the wall fold A1 behind it may be cut simultaneously diagonally from the corner along a projected cut E. - In
Fig. 5c the seam E has been cut and the redundant portion of floor covering material has been removed, after which the wall fold A1 may transition on to wall fold A2, without wedge fold D, so that the lower walls B1, B2 are covered with one layer of floor covering A. While not illustrated in the figures the seam E is preferably additionally chamfered before being filled with a heated welding material. After being filled with heated welding material thecarpet laying tool 1 is pressed into the corner with itsbase corner 2 placed in the lower corner of the wet room. The fold cuttingguide portion 3 may be placed rested on the floor B3, covered by the floor covering A, during the pressing of thetool 1 against the corner. Thebase corner 2 of thetool 1 is pressed against a slightly larger share of heated welding material which is amassed in the lower end of the diagonal seam E, distributing and forming this share to a smoother rounded corner in the wet room. Alternatively, the fold cuttingguide portion 3 may be pressed against the wall fold A1, leaving thetriangular guiding portion 8 resting on the floor B3 and thebase corner 2 pressed against the lower corner of the wet room. Preferably the portion providing the largest surface area pressed against the seam E is used. - Illustrated in
Fig. 5d the seam E has cooled down and thetool 1 is rested with thetriangular guiding portion 8 against the floor covering A on the floor B3 and the fold cuttingguide portion 3 placed against the wall fold A1. In the illustrated example the secondfold cutting guide 7 is placed parallel to the floor B3 and the user has placed a knife C or other cutting tool in one of the slits of the secondfold cutting guide 7. The user then moves thecarpet laying tool 1 along the floor B3 in a direction K, with the knife C pressed against the wall B1. In the illustrated example the knife C is supported by the secondfold cutting guide 7 above the floor B3 at a distance substantially equal to the distance L2 shown inFig. 1b , cutting down the wall fold A1 to a height fulfilling requirements in GVK's trade rules, specifically for when wall tiles are to be mounted later on the wall. - Specific embodiments of the invention have now been described. However, several alternatives are possible, as would be apparent for someone skilled in the art. For example, individually portions of the carpet laying tool may be made from different materials, such as different alloys, composite materials, plastics etc. The tool may have a tetrahedral shape formed by for example one, two or three pieces or sheets. With one sheet, the tool may be formed as the tools described in
Figs. 4a-c . With two sheets one of the sheets may be bent to form two portions, a first portion and a second portion. The portions are perpendicular to each other and the second sheet then forms a third portion which may be attached to the two portions of the bent first sheet, along two of their edges so that each portion is perpendicular to each of the other two portions. If three sheets are used to form the three respective portions they may be perpendicularly attached to each other along the edges. Each edge may be connected or attached to a coinciding edge by for example welding, gluing, riveting, etc. if they do not form a bent edge on the same piece of material. - In the examples given reference is taken from the GVK trade rules, however, different markets may have different requirements and requirements may change over time. A skilled person will realize that the fold cutting guides may be manufactured to be adapted to any such requirements and changes in requirements. Furthermore, the example illustrated in
Figs. 2a and 2b show a symmetrical tool with two fold cutting guides providing 10 cm templates, this may just as easily be 13 cm while still maintaining the angles of the triangular guiding portions. Analogously to the height of the template provided by the fold cutting guides, the angles of the triangular guiding portions may be adapted to different requirements. - Examples are given of two aligned slits with different longitudinal extension; the difference may also be in lateral extension in order to receive different breadth cutting tools. A person skilled in the arts realizes that any number of combinations of the different illustrated fold cutting guide portions and/or triangular guiding portions are also possible. Furthermore, it would be possible to interconnect any two of the described portions of the carpet laying with hinges, preferably hinges arranged on the inside, so that the outer surface of the carpet laying tool may be formed smooth. Hinges may allow the carpet laying tool to be folded into a flatter tool when not in use.
- A skilled person will realize that a handle may be formed in a wide variety of ways without departing from the invention.
- Such and other obvious modifications must be considered to be within the scope of the present invention, as it is defined by the appended claims. It should be noted that the above-mentioned embodiments illustrate rather than limit the invention, and that those skilled in the art will be able to design many alternative embodiments without departing from the scope of the appended claims.
