Technical field

The present invention relates to a jig, for cutting and / or mitring moldings, in accordance with the claims.

Technical background

In many contexts, there is a need to create aesthetically pleasing transitions between different surfaces. Aesthetically pleasing transitions between at least a first surface and at least a second surface are desired, for example in transitions between wall and ceiling, or alternatives between sections of walls. One way to achieve these aesthetically pleasing transitions is to use different types of moldings, such as, for example, ceiling moldings and so-called crown moldings.

A problem with ceiling moldings and so-called crown moldings is that these can be difficult to cut / repair so that two cut/mitred moldings fit together. It is common for incorrect cuts to occur, which means that several cuts may be required before satisfactory results are obtained. The incorrect cuts cause a great deal of irritation to the person who cuts the moldings. Furthermore, the difficulty of cutting moldings correctly means that incorrect cutting takes place so that spillage of moldings occurs. The incorrect cuts can also lead to interruptions as additional lengths of the moldings may need to be acquired to replace the lengths of the moldings that have been cut incorrectly. A more specific problem regarding the cutting of moldings is caused by how the molding is placed in the jig during cutting. Usually, the moldings are turned upside down and front and back, which essentially makes it difficult to make it clear to the user how the molding should be cut when it is placed in the jig. The user can thus not intuitively understand how to cut the molding. With the present jig, it becomes obvious, or intuitive, to the user how the molding is to be cut in the jig.

A further problem is further that known constructions of jigs and the like can be cumbersome to use and/or that these are expensive to acquire. With the present invention, said problem solves in whole or in part.

Prior Art

Patented and patent pending jigs and the like intended for use in cutting / mitring moldings are already known. An example of said jigs is a jig which is described in the patent application US10105865. The construction according to the patent application US10105865 differs substantially from the construction in accordance with the present patent application. For example, another surface, the surface 3C in Figure IB, is used on the molding as contact surfaces against the jig.

U.S. Pat. No. 4,646,368 also describes a variant of a jig which is intended for use in cutting or mitring moldings. The construction of the jig according to the patent US8646368 differs substantially from the construction of the jig in accordance with the present patent application. For example, according to the patent US8646368, the jig positions the molding towards the back 3c of the moulding. Thus, the corresponding surfaces are not used to guide the moulding in relation to the jig.

Via the patent US6481320 a further variant of a jig for cutting moldings are described. The construction according to the patent US6481320 differs significantly from the construction according to the present patent application. For example, the molding in the jig, in accordance with patent US6481320, is positioned by the surface 3c on the back of the molding. Furthermore, the jig according to the patent specification does not include a corresponding adjustable function of the size of the molding. The cutting of the molding with jig according to the patent specification further takes place in a different position than is the case in the present invention. For example, the molding is placed upside down during cutting, which means that it is not obvious to the person skilled in the art how to place it.

The Swedish patent SE538016 describes a variant of a device and a method for measuring angles and transferring the measured angles to a cutting machine. The device and the method according to the patent SE538016 differ substantially in extent from the construction of the jig in accordance with the present patent application. For example, the device according to the patent SE538016 is substantially more complicated than the construction according to the present patent application.

The object of the present invention

The object of the present invention is to eliminate or substantially reduce at least one of the previously mentioned, or mentioned in the following description, the problems with existing types of jigs which are intended to be used in cutting moldings. The object is solved with variants of the jig in accordance with the present patent application. Brief description of figures

Detailed description of the invention

With reference to the figures, a jig 1 in accordance with the present invention will be described in more detail. The jig 1 is preferably intended to be used for cutting and/or making a molding 2, several moldings 2 or similar elongate objects. In exemplary embodiments of the jig, the jig 1 is preferably intended to be used for cutting and / or mitring moldings 2 of the type of roof moldings such as so-called crown moldings. The mentioned types of moldings 2 do not, however, preclude the jig 1 from being used for cutting other types of moldings or other types of suitable elongate objects. The dimension of the moldings 2 that can be connected to the jig can vary within the scope of the inventive idea.

Referring to Figure IB, a cross-section of an exemplary molding 2 is shown which is intended to be cut and/or mitred with the jig 1. The jig 1 preferably comprises at least a first side 3 which is intended to be directed towards the wall and/or ceiling during use. The side 3 is divided into a first surface 3a which after the molding is mounted is connected to the wall, the molding further comprises at least a second surface 3b which is connected to the ceiling and at least a third surface 3c which is placed between the first surface 3a and the second surface. The molding further comprises at least one sub-surface 3d and at least one sub-surface 3e.

The sub-surfaces 3d and 3e are directed outwards from the wall and outwards from the ceiling, respectively, when the molding is mounted. The molding 2 further comprises at least one second side 4 which in use is intended to be directed outwards from the wall. The second side 4 is usually visible after the molding 2 has been set up. When the molding 2 consists of a roof molding, this comprises at least one first surface 3a which when the molding 2 is mounted contacts against the wall and at least a second surface 3b which contacts against the ceiling. The first surface 3a and the second surface 3b are perpendicular to each other or substantially perpendicular to each other. The substantially mutually perpendicular surfaces 3a and 3b are connected to the usually substantially perpendicular transition between the ceiling and the wall.

Referring to Figures 1A, 2A and 2B, it is shown that the jig 1 comprises at least a first jig part 5 and at least a second jig part 6. The construction comprises at least a first stop 7 for the molding 2 and at least a second stop 8 for the molding.

The second stop 8 comprises, is divided into, at least a first stop part 8A and at least a second stop part 8B.

The second jig part 6 is movably arranged to the first jig part 5, which means that the distance between the surfaces of the parts 7 A and the 8 A is changed (adjusted) during a preferably mutually parallel movement of the surfaces 7 A and 8B. The mutual mobility between the first jig part 5 and the second jig part 6 further means in the exemplary embodiment that the distance between the surfaces of the parts 7B and 8B can be changed (adjusted) during parallel movement of the surfaces 7B and 8B. Said mutual movement between the second jig part 6 and the first jig part 5 enables different dimensions of molding 2 to be connected to and cut / made in the jig and facilitates the connection of the molding 2 to the jig 1.

Referring to Figure 3, an exemplary first jig part 5 is shown in more detail. The first jig part 5 comprises at least a first part 9 and at least a second part 10 and at least a third part 11. The first part 9 and the second part 10 are in the exemplary embodiment perpendicular, or substantially perpendicular, connected to each other. The first part 9 and the second part 10 form an inner comer which constitutes the first stop, constituting the first stop part 7A and the second stop part 7B.

The third part 11 of the first jig part 5 is connected to the second part 10 of the first jig part 5 at a distance X from the first part 9. The distance X can vary within the scope of the inventive idea. The third part 11 is angled, according to the angle V, relative to the second part 10. Preferably, the third part 11 is angled 135 degrees, or substantially angled 135 degrees, relative to the second part 10. The third part 11 may be connected to or integrated with the second part 10.

Referring to Figure 3, it is shown that in the exemplary embodiment, the third part 11 of the first jig part 5 comprises at least one space 14 grooves, recess open part or the like. The space 14 extends in the longitudinal direction of the third part 11 from the second part 10 to the free end of the third part 11. At the free end of the third part 11 the space is open, which means that the second jig part 6 can be inserted in and out of the space 14. The space 14 is further open in the direction of the molding 2. The space 14 is delimited in a first edge 15 and at least one second edge 16. The first edge 15 and the second edge 16 are preferably parallel or substantially parallel to each other. The first edge 15 is in the exemplary embodiment provided with at least one first groove 17, recess, and the second edge 16 is in the exemplary embodiment provided with at least one second groove 18, recess. The grooves are directed in the longitudinal direction of the edge. The first groove 17 extends after the edge 15 of the third part 11 and the second groove 18 extends after the second edge 16 of the third part 11. In the exemplary embodiment, the first groove 17 is V-shaped towards the recess 14 and the second the groove 18 is V-shaped, preferably internal V-shape, towards the recess 14 (on each side of the recess).

Referring to Figures 4A - 4C, the second jig part 6 is shown in more detail. The second jig part 6 comprises a substantially rectangular part 19 which has a first long side 20 and an opposite long side 21 and a first short side 22 and at least one opposite short side 23. The rectangular part 19 further has a first side 24, surface, which is directed towards the molding 2 and a second side 25, surface directed from the molding 2. The second jig part 6 further comprises at least a first spacer part 26A which extends a partial distance from the first side 24 of the rectangular part 19 in the second jig part. Further includes at least one second spacer 26B. The spacer portion 26 A is connected at its one end 27 to the lower portion 24 of the first side 24. The spacer 26 is connected at its other end 28 to the second spacer 26B. The stop 7 comprises at least a first contact surface 29 against the molding 2 and at least a second contact surface 30 against the molding 2. The first contact surface 29 and the second contact surface 30 are in the embodiment perpendicular, or substantially perpendicular, to each other. The first contact surface 29 contacts against the edge part of the molding which, when mounted, contacts against the ceiling or wall.

The first short side 22 has in the exemplary embodiment an external V-shape which fits into the internal V-shape of the groove 17. The opposite short side 23 of the second jig part 6 rectangular part 19 further has a V-shape which fits into the second V-shaped groove 18. In alternative embodiments, the shape of the first groove 17 and the shape of the first short side 22 and the shape of the second groove 18 and the shape of the opposite the short side 23 be of a shape suitable for the purpose other than the said V-shapes. Preferably, the shape of the short sides 22 and 23 and the grooves 17 and 18 on the short sides are of the cooperating shapes type. By said cooperating shapes is meant shapes which fit into each other, for example, and which in the exemplary embodiment of an inner V-shape and an outer V-shape.

The second jig part 6 is movably connected to the space 14 in the third part 11 of the first jig part 5. By said movable connection the distance between the first stop part 7 A in relation to the first contact surface 8A can be varied. Said mobility is achieved by the short side 22 of the second jig part 6 running in the first groove 17 and the second short side 23 of the second jig part 6 running in the second groove 18.

The present jig 1 comprises at least one damping device 28, locking device or the like with which the third part 16 can be temporarily locked to the second jig part 6. Preferably the distance between the surfaces 7A and 8A can be adjusted stepless but said sleeplessly adjustment does not preclude the adjustment of mutual positions between the surfaces in alternative embodiments can take place step by step.

The damping function, the locking function, can be achieved with the help of several different techniques. In the exemplary embodiment, this is achieved in that the damping device 28, the locking device, comprises at least one first damping means 29, locking means which springs in the direction of one of the grooves 17 or 18. In a second embodiment of the damping device, the damping device comprises at least one first damping means 29, locking means, which springs in the direction of the groove 17 and at least one second damping means 30, locking means, which springs towards the second groove 18. The resilient effect can be achieved via several different techniques. For example, this is achieved by a resilient material placed between the first damping means 29 and the second damping means 30. Alternatively, the damping means 29 alternatively the damping means 29 and 30 comprise materials with resilient or resilient effect. In alternative embodiments, another damping device suitable for the purpose may be used to temporarily dampen, or lock, the second part and the first part together.

Referring to Figure 5A, the use of the present jig 1 connected to a saw box 33, alternative designation, mitring box or the like is shown. When using the jig 1 in a saw box 33, the molding 2 is connected to the jig 1. The jig 1 is either already placed in the saw box 33 or the jig 1 with associated molding 2 is moved to the saw box 33 after which it is sawn. After the gig 1 and the molding 2 are placed in the saw box 33, the strip is sawn in the usual way in the saw box.

Referring to Figure 5B, the use of the present jig is shown in a cutting machine 34, cutter or the like. The cutting takes place in the cutting machine 34 in the usual way. The advantage is that the molding 2 is directed in such a way that it is understood if it is correctly positioned in relation to the blade of the cap.

When using the jig 1, the molding 2 is placed at a corresponding position in the jig 1 as this is placed in the transition between the wall and the ceiling. The present jig 1 thus becomes intuitive to understand how the jig 1 is used when cutting molding.

In the detailed description of the present jig 1, details in the construction of the jig may be omitted which will be apparent to a person skilled in the art within the scope of the jig. Such obvious details are included to the extent required for a proper function of the present jig 1 to be obtained.

Although certain preferred embodiments of the jig 1 have been described in more detail, variations, and modifications of the jig 1 may be apparent to those skilled in the art within the scope of the jig. All such modifications to the jig are considered to fall within the scope of the appended claims.
