Background Art

[0002] As shown in FIGS. 8 and 9, a skateboard 100 has a deck 101. Here, the deck 101 is the main body plate of the skateboard 100.

[0003] As shown in FIG. 9, a truck 102 is attached to the lower side 101D of the deck 101. Here, the truck 102 is a fitting attached to the lower side 101D of the deck 101, and tires 103 are mounted on both sides of the truck 102. Therefore, the truck 102 serves like a handle of a bicycle.

[0004] As shown in FIG. 10, holes 101H for attaching the truck 102 are provided in the deck 101. As shown in FIGS. 8 to 10, the deck 101 and the truck 102 are fixed by inserting screws 104 into such holes 101H.

[0005] Also, as shown in FIG. 8, a deck tape 110 is pasted on the surface side 101S of the deck 101. Here, the deck tape 110 is a tape with fine irregularities on the surface that serves as an anti-slip.

[0006] In the process of replacing such a deck tape 110, holes for inserting the screw 104 were made in the deck tape 110 by tools such as needles and drivers.

Summary of the Invention

Problems to be Solved by the Invention

[0008] However, the process of replacing the deck tape 110 as described above involves three steps: shaping the deck, cutting it, and drilling holes. This requires multiple tools such as a utility knife and a screwdriver, which makes the process complicated.

[0009] Furthermore, in the process of replacing the grip tape 110 as described above, tools such as screwdrivers are used to make holes in the grip tape 110, but since these tools are not sized specifically for skateboards, there was a problem in that there was a risk of accidentally stabbing one's hand when piercing the grip tape 110.

[0010] Therefore, this disclosure has been made in view of the above-mentioned problems, and aims to provide a cutter knife that can perform the three steps of the deck tape 110 replacement process. [Means for solving the problem]

[0011] The first feature of this disclosure is a cutter knife comprising a blade body and a holder for housing the blade body, wherein the holder has a front surface, a rear surface opposite to the front surface, a front surface, a back surface opposite to the front surface, and two opposing side surfaces, the blade body is configured to slide within the holder and protrude from a hole provided on the front surface, and a pointed member is provided on either the front surface, the rear surface, or the side surfaces. [Effects of the Invention]

[0012] According to this disclosure, a cutter knife capable of performing three steps in the process of replacing the deck tape 110 can be provided. [Brief explanation of the drawing]

[0014] Preferred embodiments of the present invention will be described in detail below with reference to the attached drawings. In the following drawings, identical or similar parts are denoted by the same or similar reference numerals. However, it should be noted that the drawings are schematic, and the ratios of dimensions, etc., may differ from those of reality. Therefore, specific dimensions, etc., should be determined by referring to the following description. Furthermore, there may be parts in the drawings where the relationships and ratios of dimensions differ from those of other parts. In this specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals to avoid redundant explanations, and elements not directly related to the present invention are omitted from the illustration.

[0015] (First Embodiment) Hereinafter, referring to FIGS. 1 to 7, the cutter knife 1 according to the first embodiment of the present invention will be described.

[0016] FIG. 1 is a diagram showing an example of the configuration of the cutter knife 1 according to the present embodiment, FIG. 2 is a view of the cutter knife 1 seen from the direction D1, FIG. 3 is a view of the cutter knife 1 seen from the direction D2, FIG. 4 is a view of the cutter knife 1 seen from the direction D3, FIG. 5 is a view of the cutter knife 1 seen from the direction D4, FIG. 6 is a view of the cutter knife 1 seen from the direction D5, and FIG. 7 is a view of the cutter knife 1 seen from the direction D6.

[0017] As shown in FIG. 1, the cutter knife 1 according to the present embodiment includes a blade body 10 and a holder 20 that houses the blade body 10.

[0018] As shown in FIGS. 1 to 7, the holder 20 has a front end surface 20A, a rear end surface 20B facing the front end surface 20A, a front surface 20C, a rear surface 20D facing the front surface 20C, and two opposing side surfaces 20E / 20F.

[0019] As shown in FIG. 1, the blade body 10 is configured to slide within the holder 20 and protrude from a hole 20H provided in the front end surface 20A.

[0020] Specifically, as shown in FIGS. 1 and 4, a groove 21 extending in the longitudinal direction L is provided in the central portion in the width direction W on the front surface 20C side of the holder 20, and the blade body 10 is accommodated within such a groove 21.

[0021] The user can slide the blade body 10 in the longitudinal direction L by sliding a slider 22 that is accommodated within the groove 21 and attached to the blade body 10 in the longitudinal direction L.

[0022] As shown in Figures 1, 3-5, and 7, the slider 22 is configured to be detachable from the holder 20 at the rear end 20B. The user can replace the blade 10 by removing the slider 22 and the blade 10 from the holder 20.

[0023] In the holder 20, a pointed member 30 is provided on either the front end surface 20A, the rear end surface 20B, or the side surfaces 20E / 20F.

[0024] For example, as shown in Figures 1 to 5 and Figure 7, a pointed member 30 may be provided in the holder 20 near the corner 20X formed by the rear end surface 20B and the side surface 20E.

[0025] Here, the pointed member 30 has a pointed tip portion, such as a needle shape or a screwdriver shape.

[0026] For example, the material of the tip portion is preferably tungsten carbide, a type of cemented carbide. Furthermore, the diameter of the tip portion is preferably between 3 mm and 10 mm. Additionally, the exposed portion of the tip portion is preferably between 2 mm and 10 mm.

[0027] Note that the pointed member 30 does not include any member whose tip is split into two.

[0028] With this configuration, the user can perform the deck shaping process using the back surface 20D, the cutting process using the blade 10, and the drilling process using the pointed member 30 (the tip portion thereof) during the process of replacing the deck tape 110.

[0029] In other words, with the above configuration, the user can perform the three steps of the deck tape replacement process with a single tool (the cutter knife 1 according to this embodiment).

[0030] Furthermore, by using tungsten carbide as the material for the tip portion of the pointed member 30, it is possible to make holes in deck tape 110 of any material.

[0031] Here, by making the pointed member 30 a size suitable for replacing skateboard grip tape, safety is improved as it is less likely to accidentally stab the hand when piercing the grip tape 110.

[0032] As shown in Figure 1, the pointed member 30 may protrude diagonally in direction D7 relative to the rear end face 20B and side surface 20E of the holder 20. When the pointed member 30 protrudes diagonally in this way, it is less likely to slip when gripping the holder 20 and making it easier to use. Also, if the pointed member 30 protrudes vertically, there is a risk of fingers being caught between the holder 20 and the deck, so the risk of fingers being caught is reduced when the pointed member 30 protrudes diagonally.

[0033] The back surface of the holder 20 may be a smooth surface without any irregularities. In this case, the entire back surface of the holder 20 may be flat or curved.

[0034] Furthermore, as shown in Figures 2, 6, and 7, the back surface 20D of the holder 20 may have a convex curved surface.

[0035] With these configurations, the user can use the back surface 20D as a spatula to fold the grip tape 110 attached to the deck 101 to conform to the outer shape of the deck 101, shape the deck, use the blade 10 to cut off excess grip tape 110, and use the pointed member 30 to make holes in the grip tape 110.

[0036] Although the present invention has been described in detail using the embodiments described above, it will be clear to those skilled in the art that the present invention is not limited to the embodiments described herein. The present invention can be implemented in modified and altered forms without departing from the spirit and scope of the invention as defined by the claims. Therefore, the description herein is for illustrative purposes only and is not intended to be restrictive in any way to the present invention. [Explanation of Symbols]
