Description

The present invention relates to a cutting mat that is used as a base for materials to be cut, such as paper, film materials, and sheet materials, when cutting the materials with a blade such as a cutter or knife.

Cutting mats with various functions have been proposed for use as a base when cutting paper, film materials, sheet materials, etc. with a blade such as a cutter or knife. One example related to the present invention is the "cutting mat with stopper" described in Patent Document 1.

The "cutting mat with stopper" has soft or soft foamed synthetic resin plates on both sides, the synthetic resin plate on the front side has a surface layer with densely formed fine dot-like protrusions that prevent blade scratches, and between these two soft synthetic resin plates, a ferromagnetic or magnetic layer made of a hard synthetic resin plate as a base and a very thin steel plate is fused and integrated to form a mat part, and a stopper with a hinge part that can be opened and closed freely and can be attached and detached by the ferromagnetic or magnetic layer on the soft synthetic resin plate on the front side is attached along the edge of this mat part.

Japanese Utility Model Application Publication No. 58-140097

The "cutting mat with stopper" described in Patent Document 1 is convenient when using a cutter, because the stopper can fix the paper or other object to be cut placed on the surface of the cutting mat by adsorption, but it is necessary to provide a ferromagnetic layer in the middle of the synthetic resin plate and form the stopper from a magnetic material, or to provide a magnetic layer in the middle of the synthetic resin plate and form the stopper from a ferromagnetic material, so the structure is complex, and many types of materials are required to manufacture the cutting mat itself, which is also time-consuming.

In addition, the adhesive force of the stopper that holds the workpiece in place utilizes the magnetic force (adhesive force) that occurs between the cutting mat and the stopper. Therefore, if the thickness of the workpiece that is sandwiched between the surface of the cutting mat and the stopper increases, the magnetic force (adhesive force) decreases rapidly, and the workpiece may no longer be able to be stably fixed.

The problem that this invention aims to solve is to provide a cutting mat that has a relatively simple structure, is easy to manufacture, and can stably hold the object to be cut even if the thickness of the object increases.

The cutting mat of the present invention is characterized in that it comprises a flat mat body that is placed under a material to be cut, which is made of paper, film material, or sheet material, when the material is cut with a cutter or knife , and a clip that detachably holds a portion of the area where the periphery of the material to be cut placed on the surface of the mat body overlaps with the periphery of the mat body.

In the above-mentioned cutting mat, when the mat body is placed on a specified work surface with a portion of its peripheral edge clamped, a storage space for the lower part of the clip protruding downward from the back surface of the mat body can be provided on the back surface of the mat body to prevent the lower part of the clip from abutting the work surface.

The present invention provides a cutting mat that has a relatively simple structure, is easy to manufacture, and can stably hold the object to be cut even if the thickness of the object increases.

The cutting mats 10, 20, 30, 40, 50, 60, and 70 according to the embodiments of the present invention will be described below with reference to Figures 1 to 13. Note that among the components of the cutting mats 10, 20, 30, 40, 50, 60, and 70, parts that have common shapes and functions will be given the same reference numerals in Figures 1 to 13, and descriptions thereof may be omitted.

First, the cutting mat 10 will be described with reference to Figs. 1 to 3. As shown in Figs. 1 and 2, the cutting mat 10 comprises a flat mat body 1 that is placed under the material P to be cut, such as paper, film material, or sheet material, when the material P is cut with a blade such as a cutter or knife, and a clip 2 that detachably holds a part of the area where the peripheral edge Pf of the material P to be cut placed on the surface 1a of the mat body 1 overlaps with the peripheral edge 1f of the mat body 1. The surface 1a of the mat body 1 is made of a material that is unlikely to leave scratches even when cutting is performed with a blade such as a cutter or knife. The planar shape of the mat body 1 is a rectangle with rounded corners, but is not limited to this.

As shown in FIG. 3, when the mat body 1 is placed on a predetermined work surface 3 with a portion of the periphery 1f of the mat body 1 clamped by the clip 2, a storage space S for the lower portion 2b of the clip 2 is provided on the back surface 1b side of the mat body 1 to prevent the lower portion 2b of the clip 2, which protrudes downward from the back surface 1b of the mat body 1, from contacting the work surface 3. The storage space S is formed by adhering a spacer member 4 to the back surface 1b of the mat body 1 and adhering a substrate 5 to the back surface 4b of the spacer member 4. The substrate 5 is formed of a material with higher rigidity (a material that is less likely to bend or deform) than the mat body 1 and the spacer member 4.

The spacer member 4 is a flat rectangular member, and the length of each of its four sides is smaller than the length of the four sides of the mat body 1, so that an accommodation space S is formed all around the spacer member 4. The outer peripheral shape of the substrate 5 attached to the back surface 4b of the spacer member 4 is a flat rectangular shape with rounded corners of the same size as the mat body 1, and the thickness of the substrate 5 is greater than the thickness of the mat body 1. Note that even if the substrate 5 is omitted, the accommodation space S for the lower part 2b of the clip 2 can be formed on the back surface 1b side of the mat body 1.

There are no restrictions on how the cutter mat 10 can be used, but for example, as shown in FIG. 3, the workpiece P to be cut is placed on the surface 1a of the mat body 1, and a portion of the area where the periphery Pf of the workpiece P overlaps with the periphery 1f of the mat body 1 is clamped with at least one clip 2, so that the workpiece P can be fixed on the surface 1a of the mat body 1. This allows the workpiece P to be stably held on the surface 1a of the mat body 1, making the cutting operation easy and accurate and improving safety during the cutting operation.

Although not limited to this, in this embodiment, a resilient pressure type open-close clip, also known as a double clip, is used as the clip 2, so that it can be attached to any part of the area where the periphery Pf of the material to be cut P and the periphery 1f of the mat body 1 overlap, and the periphery Pf of the material to be cut P and the periphery 1f of the mat body 1 can be stably clamped. Because the clip 2 is a resilient pressure type open-close clip, a stable clamping force can be obtained even when the material to be cut P is thick or when multiple materials to be cut P are cut in layers.

In addition, when cutting by placing a template or ruler formed to resemble the shape to be cut on the material P to be cut, the template or ruler can be overlapped with the material P to be cut and clamped with the clip 2, allowing for accurate and safe cutting work. Furthermore, the cutting mat 10 is made by stacking the flat mat body 1, spacer member 4, and substrate 5 and combining them with the clip 2, so it has a relatively simple structure and is easy to manufacture.

Next, the cutting mat 20 will be described with reference to Figures 4 to 6. As shown in Figures 4 and 5, the cutting mat 20 has a protruding portion 6 on the surface 1a of the mat body 1 near the peripheral edge 1f on the short side of the mat body 1, which is capable of contacting a part of the peripheral edge Pf of the workpiece P placed on the surface 1a of the mat body 1.

There are no restrictions on how the cutting mat 20 can be used. For example, when placing the material P to be cut on the surface 1a of the mat body 1, as shown in FIG. 6, a part of the periphery Pf of the material P to be cut is abutted against the protruding portion 6 to position it, and then a part of the area where the periphery Pf of the material P to be cut and the periphery 1f of the mat body 1 overlap is clamped with the clip 2, so that the material P to be cut can be fixed in the correct position and in the correct posture, which makes the positioning work easier and improves the accuracy of the cutting work.

The position and number of protrusions 6 on the cutting mat 20 are not limited, so as shown in FIG. 4, a protrusion 6a can be provided on the portion of the surface 1a of the mat body 1 near the peripheral edge 1f on the long side, or multiple protrusions 6a, 6b can be provided. In the cutting mat 20, the position of the protrusions 6 on the surface 1a of the mat body 1 is fixed, but the fixed position of the protrusions 6 can also be made changeable.

Next, the cutting mat 30 will be described with reference to Figures 7 and 8. As shown in Figures 7 and 8, the cutting mat 30 comprises a flat mat body 1 that is placed under the material to be cut P, and an elastic pressing clip 7 provided on the peripheral edge 1f of the long side of the surface 1a of the mat body 1. The clip 7 comprises a pressing member 7a whose front edge 7c can rise and fall around the hinge portion 7b, and an elastic body (not shown) that biases the front edge 7c of the pressing member 7a to press the surface 1a of the mat body 1.

As shown in FIG. 8, the cutting mat 30 has an anti-slip member 8 attached to the back surface 1b of the mat body 1. There are no restrictions on the type of anti-slip member 8, so it is preferable for it to be made of a material that generates strong friction with the work surface 3, such as a flat plate of natural rubber or synthetic rubber.

There are no restrictions on how the cutting mat 30 can be used, but as shown in Figures 7 and 8, by pinching a portion of the peripheral edge Pf of the long side of the material P to be cut placed on the surface 1a of the mat body 1 between the surface 1a of the mat body 1 and the pressing member 7a of the clip 7, a portion of the peripheral edge Pf of the material P to be cut can be pressed and locked onto the surface 1a of the mat body 1. This allows the material P to be stably held on the surface 1a of the mat body 1.

As mentioned above, the cutter mat 30 has an anti-slip member 8 on the back surface 1b of the mat body 1, which prevents the mat body 1 placed on the work surface 3 from sliding on the work surface 3, improving workability and safety during cutting operations.

Next, the cutting mat 40 will be described with reference to Figures 9 and 10. As shown in Figures 9 and 10, the cutting mat 40 comprises a flat mat body 1 that is placed under the material P to be cut, and a resilient pressing clip 7 provided on the peripheral edge 1f of the short side of the front surface 1a of the mat body 1. The mat body 1 is placed on a substrate 5 having four sides each longer than the four sides of the mat body 1, and an anti-slip member 8 is attached to the back surface 5b of the substrate 5.

The cutter mat 40 can be used in the same manner as the cutter mat 30 shown in Figures 7 and 8, but the cutter mat 40 has four sides that are longer than the four sides of the mat body 1, and the mat body 1 is placed on a substrate 5 that is thicker than the mat body 1, so it is more stable during cutting operations.

Next, we will explain the cutting mats 50, 60, and 70 based on Figures 11, 12, and 13.

In the cutting mat 50 shown in FIG. 11, a clip 7 is provided in the center of the portion of the surface 1a of the mat body 1 near the peripheral edge 1f on the long side, and multiple protrusions 6c, 6c are provided to sandwich the clip 7, so that the peripheral edge Pf of the workpiece P placed on the surface 1a of the mat body 1 can be pressed and held by the pressing member 7a of the clip 7 in an accurately positioned state by abutting against the protrusions 6c, 6c.

In the cutter mat 60 shown in FIG. 12, a clip 7 is provided at the center of the portion of the surface 1a of the mat body 1 near the peripheral edge 1f on the long side, and multiple protrusions 6c, 6d of different lengths are provided to sandwich the clip 7. A clip 7 is also provided at the center of the portion of the surface 1a of the mat body 1 near the peripheral edge 1f on the short side.

As a result, the peripheral edge Pf of the object P placed on the surface 1a of the mat body 1 can be abutted against the protruding parts 6c and 6d, accurately positioned, and pressed and held by the pressing members 7a of the multiple clips 7, allowing the object P to be stably held.

In the cutter mat 70 shown in FIG. 13, a clip 7 is provided in the center of the portion of the surface 1a of the mat body 1 near the peripheral edge 1f on the short side, and multiple protrusions 6d, 6d are provided to sandwich the clip 7. In addition, a protrusion 6c is provided in the portion of the surface 1a of the mat body 1 near the peripheral edge 1f on the long side.

As a result, the peripheral edge Pf of the short side of the object P placed on the surface 1a of the mat body 1 can be abutted against the protruding portions 6d, 6d on the short side, and the peripheral edge Pf of the long side of the object P can be abutted against the protruding portion 6c on the long side, and pressed and held in position by the pressing member 7a of the clip 7, improving the positioning accuracy of the object P.

Note that the cutter mats 10, 20, 30, 40, 50, 60, and 70 described based on Figures 1 to 13 are examples of the cutter mats according to the present invention, and the cutter mats according to the present invention are not limited to the cutter mats 10, 20, 30, 40, 50, 60, and 70 described above.

The cutting mat of the present invention can be widely used in industrial fields that require cutting materials such as paper, film materials, and sheet materials with a blade such as a cutter or knife.
