Description

[Technical Field]

[0001] The present invention relates to tools such as pliers. [Background technology]

[0002] For example, in aircraft maintenance sites, the loss of tools such as pliers is directly linked to safety, so thorough tool management is carried out.

[0003] As shown in Patent Document 1, conventional pliers have an electronic tag attached to one of the pair of grips held by the worker, and are configured to enable wireless communication between the electronic tag and a reader. This configuration makes it possible to manage, for example, whether the pliers have been returned to a toolbox.

[0004] However, the pliers shown in Patent Document 1 have an electronic tag attached to their outer surface, which can get in the way of work, resulting in a problem of reduced workability. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] U.S. Patent No. 10,807,228 Summary of the Invention [Problem to be solved by the invention]

[0006] Therefore, the present invention has been made to solve the above-mentioned problems, and its main objective is to make it possible to manage tools while also ensuring workability. [Means for solving the problem]

[0007] In other words, the tool of the present invention is a tool for clamping or cutting objects, and is characterized by having a pair of rotatably connected gripping parts and an electronic tag provided inside one or both of the gripping parts.

[0008] With a tool configured in this manner, an electronic tag is provided inside the grip, so that the tool can be managed without the electronic tag getting in the way of work, ensuring workability.

[0009] It is preferable that the gripping portions are gripped at the outside, and the electronic tag is provided on the inside of one or both of the gripping portions. This reduces the amount of force applied to the electronic tag during work, making it possible to prevent damage to the electronic tag.

[0010] A specific example of a mode for providing an electronic tag inside the grip portion is a mode in which a recess is formed in the grip portion and the electronic tag is provided in the recess.

[0011] However, if the handle is made of a metal body and the grip covers the main body, some of the radio waves emitted from the electronic tag will be reflected by the main body, causing the radio waves to cancel each other out and become weaker, resulting in a loss of communication stability. Therefore, in the case of the above-described configuration, it is preferable that the recessed portion is formed in the grip, and that a part of the grip is interposed between the electronic tag provided in the recessed portion and the main body. In this case, a portion of the non-metallic grip is interposed between the main body and the electronic tag, which prevents the radio waves emitted from the electronic tag from being reflected by the main body, ensuring stable communication.

[0012] It is preferable that the recessed portion has a central portion in which the electronic tag is housed and a stepped portion provided at least partially around the central portion, and that a lid body that closes the recessed portion is attached to the stepped portion. With this configuration, the waterproofing of the recessed portion can be ensured by, for example, welding or adhering the lid to the surface of the stepped portion.

[0013] It is preferable that the electronic tag is elongated along the grip portion. This allows the electronic tag to emit radio waves over a wider range, making communication between the electronic tag and the reader more reliable.

[0014] In order to further ensure communication between the electronic tag and the reader, it is preferable that the electronic tag be provided inside each of the pair of gripping portions.

[0015] Incidentally, as a mode for sealing the electronic tag provided in the recessed portion, for example, a mode is conceivable in which a resin such as an ultraviolet curable resin, a thermosetting resin, or an adhesive is poured into the recessed portion and cured. In this case, it is preferable that the recessed portion is formed by a bottom surface and a pair of longitudinal side surfaces and a pair of lateral side surfaces surrounding the bottom surface, and that the longitudinal side surfaces have a plurality of irregularities formed along the longitudinal direction. According to this configuration, the resin that has entered between the plurality of recesses and protrusions is caught by the recesses and protrusions, making it difficult for the resin or the electronic tag sealed in the resin to come off.

[0016] In order to more reliably prevent the resin and the electronic tag from coming off, it is preferable that each of the pair of longitudinal side surfaces has the plurality of projections and recesses.

[0017] It is preferable that some or all of the irregularities have irregular shapes. In this case, the unevenness will have a complex shape, and the resin will be caught by the unevenness, making it more difficult to remove.

[0018] It is preferable that at least one recess of the plurality of projections and recesses has a tapered shape that is narrower on the opening side of the recess than on the bottom side of the recess. In this case, the resin is caught on the left and right sides of the trapezoidal convex portion, making it more difficult to come off. [Effects of the Invention]

[0019] According to the present invention configured in this manner, it is possible to manage tools while also ensuring workability. [Brief explanation of the drawings]

[0021] <<First Embodiment>> A first embodiment of the tool according to the present invention will be described below.

[0022] The tool according to this embodiment is used in the maintenance of aircraft, vehicles, railroad cars, ships, etc., for clamping or cutting objects, and specifically is a pair of pliers.

[0023] As shown in Figures 1 and 2, this tool 100 has a pair of rotatably connected main bodies 10 and a pair of gripping portions 30 each having a grip 20 attached to the rear end 11 of the main bodies 10, and by opening and closing the pair of gripping portions 30, the tip end 12 of the main body 10 opens and closes in conjunction with this.

[0024] As a specific configuration, the tip portion 12 may be configured to open by opening the pair of gripping portions 30, or the tip portion 12 may be configured to open by closing the pair of gripping portions 30.

[0025] Each of the main bodies 10 is made of metal, and a connecting portion 13 is provided between the front end portion 12 and the rear end portion 11 described above.

[0026] As shown in FIG. 1, the pair of gripping portions 30 are gripped by an operator at their outer sides, and are connected to each other so as to be rotatable relative to each other.

[0027] The grip 20 that constitutes the holding portion 30 is long and made of a non-metal material such as resin, but it does not necessarily have to be made of resin and may be made of wood, cloth, or leather, for example.

[0028] Therefore, as shown in Figures 2 and 3, this tool 100 further includes an electronic tag 40 provided inside one or both of the gripping portions 30, and in this embodiment, the electronic tag 40 is provided only on one of the gripping portions 30.

[0029] The electronic tag 40 communicates wirelessly with a reader (not shown), and stores various information that can be read by the reader.

[0030] Specifically, as shown in FIG. 3, the electronic tag 40 has at least an IC chip 41 and an antenna 42 on which the IC chip 41 is provided.

[0031] In this embodiment, the electronic tag 40 has an elongated shape along the grip 20, and the antenna 42 forms a closed loop.

[0032] 2 and 3, the electronic tag 40 is provided inside the grip 20, specifically on the inside opposite to the outside of the grip 20. The outside of the grip 20 is the side that the operator's palm touches, and the inside of the grip 20 is the side facing the other holding part 30.

[0033] More specifically, as shown in FIGS. 2 and 3, the grip 20 of this embodiment has a recess 21 formed therein, and the electronic tag 40 is housed in this recess 21.

[0034] As shown in Figures 4 and 5, this recess 21 is formed by recessing the inner surface of the grip 20, and is formed by a bottom surface 211 and a side surface 212 surrounding the bottom surface 211, and is closed by a lid body 50 with the electronic tag 40 stored inside.

[0035] The recess 21 of this embodiment is elongated and has a step so that the central portion 21a is deeper than the entire periphery. That is, as shown in Fig. 5, the recess 21 has the central portion 21a in which the electronic tag 40 is housed, and a step portion 21b provided around the central portion 21a. The step portion 21b is where the above-mentioned lid 50 is fitted and attached without any play, and in this embodiment, the waterproofness of the recess 21 can be ensured by welding or adhering the lid 50 to the step portion 21b.

[0036] It should be noted that the recess 21 does not necessarily need to have step portions 21b around the entire periphery, and step portions 21b may be provided only around at least a portion of the periphery of the central portion 21a, for example, by providing step portions 21b only at both longitudinal ends of the recess 21.

[0037] An electronic tag 40 is housed in the center of this recess 21 and is adhered thereto with, for example, an adhesive.

[0038] With this configuration, a part of the grip 20 is interposed between the electronic tag 40 and the main body 10 .

[0039] According to the tool 100 configured in this manner, the electronic tag 40 is provided inside the gripping portion 30, so that the tool 100 can be managed while the electronic tag 40 does not get in the way of work, and workability can be ensured.

[0040] Furthermore, since the electronic tag 40 is provided inside one of the gripping portions 30, force is less likely to be applied to the electronic tag 40 during work, and damage to the electronic tag 40 can be prevented.

[0041] Furthermore, since a part of the resin grip 20 is interposed between the electronic tag 40 and the main body 10, it is possible to prevent the radio waves emitted from the electronic tag 40 from being reflected by the metal main body 10, thereby ensuring the stability of communication.

[0042] Furthermore, since the electronic tag 40 is elongated along the gripping portion 30, radio waves can be emitted from the electronic tag 40 over a wider range, making communication between the electronic tag 40 and the reader more reliable.

[0043] <<Modification of the First Embodiment>> The present invention is not limited to the first embodiment.

[0044] For example, in the above embodiment, the antenna 42 constituting the electronic tag 40 forms a closed loop, but as shown in FIGS. 4 and 5, it may also be U-shaped.

[0045] In the configuration of FIGS. 4 and 5, the electronic tag 40 is housed in the recess 21 while being held by the holder 60. The holder 60 is made of, for example, flexible plastic or silicone rubber, and is adhered to the recess 21 by, for example, an adhesive.

[0046] Furthermore, in the above embodiment, the point where the grip 20 is attached to the rear end 11 of the main body 10 is described as the gripping portion 30, but for example, if the rear end 11 of the main body 10 is made of a non-metal material such as resin, the rear end 11 of the main body 10 may become the gripping portion 30, and an electronic tag 40 may be provided inside this gripping portion 30.

[0047] Furthermore, in the above embodiment, the recess 21 was closed by the lid 50, but the electronic tag 40 may also be sealed by pouring a resin such as an ultraviolet curing resin, a thermosetting resin, or an adhesive into the recess 21 containing the electronic tag 40 and allowing it to harden.

[0048] <<Second embodiment>> Next, a second embodiment of the tool according to the present invention will be described.

[0049] The tool 100 according to this embodiment is a pair of pliers, and differs from the first embodiment in particular in the configuration of the grip 20, and this point will be described.

[0050] As shown in FIG. 6, the grip 20 of this embodiment has a hill 70 that rises inward from the inner surface, and this hill 70 has a recess 21 formed therein in which the electronic tag 40 is housed.

[0051] This recess 21 is formed by a bottom surface 211 and side surfaces 212 surrounding the bottom surface 211, similar to the previous embodiment.

[0052] More specifically, as shown in FIG. 7, the recess 21 is elongated along the grip 20, and the bottom surface 211 is surrounded by a pair of longitudinal side surfaces 212a extending along the longitudinal direction of the recess 21 and a pair of lateral side surfaces 212b extending along the lateral direction intersecting the longitudinal direction.

[0053] The longitudinal side surface 212a has a plurality of irregularities 81, 82 formed along the longitudinal direction.

[0054] The plurality of projections and recesses 81, 82 are made up of alternately arranged recesses 81 and projections 82, and here, each of the pair of longitudinal side surfaces 212a has the plurality of projections and recesses 81, 82.

[0055] As shown in FIG. 7, these irregularities 81, 82 are formed on the longitudinal side surface 212a closer to the bottom surface 211 than the opening edge 213 of the recess 21; in other words, the opening edge 213 of the longitudinal side surface 212a is a flat surface.

[0056] 7, the recesses 81 have the same shape before the grip 20 is attached to the main body 10, and here, they are rectangular when viewed from the opening of the recess 21, and the recess bottom surface 811 is also rectangular. Note that the shape of the recess 81 when viewed from the opening and the shape of the recess bottom surface 811 may be various shapes such as a square, a rectangle, or a trapezoid.

[0057] 7, the plurality of protrusions 82 have the same shape before the grip 20 is attached to the main body 10, and here they are rectangular when viewed from the opening of the recess 21, and the protrusion upper surfaces 821 are also rectangular. Note that the shape of the protrusions 82 when viewed from the opening and the shape of the protrusion upper surfaces 821 may be various shapes such as a square, a rectangle, or a trapezoid.

[0058] 8, when grip 20 is attached to main body 10, rear end 11 of main body 10 is bent, and grip 20 also bends along rear end 11, causing the shapes of multiple projections and recesses 81, 82 to become distorted and irregular. Note that the distortion of projection top surface 821 is slight compared to the distortion of recess bottom surface 811, and is practically imperceptible to the naked eye.

[0059] That is, when the grip 20 is attached to the main body 10, all or some of the recessed portion bottom surfaces 811 of the plurality of recessed portions 81 have shapes different from one another.

[0060] More specifically, as shown in the partially enlarged view of Figure 9, at least one of the multiple recesses 81 has a narrowed shape that is narrower on the opening side of the recess 21 than on the bottom surface 211 side of the recess 21, and here, multiple adjacent recesses 81 have this narrowed shape.

[0061] In such a configuration, as shown in Figure 9, a resin 90 such as an ultraviolet curing resin, a thermosetting resin, or an adhesive is poured into the recess 21 that houses the electronic tag 40 and hardened, and the electronic tag 40 is sealed by this resin 90.

[0062] According to the tool 100 configured in this manner, the resin 90 poured into the recessed portion 21 penetrates between the plurality of irregularities 81, 82, and after hardening, the resin 90 is caught by the irregularities 81, 82, making it difficult for the resin 90 and the electronic tag 40 sealed in the resin 90 to come off.

[0063] Furthermore, since each of the pair of longitudinal side surfaces 212a has a plurality of irregularities 81, 82, it is possible to more reliably prevent the resin 90 and the electronic tag 40 from falling off.

[0064] Since the adjacent recesses 81 have a narrower shape that is narrower on the opening side of the recess 21 than on the bottom surface 211 side of the recess 21, the hardened resin 90 catches on the left and right sides of these protrusions 82, making it more difficult for the resin 90 and the electronic tag 40 to come off.

[0065] Incidentally, the resin 90 poured into the recess 21 reduces in volume when it cools and hardens, causing a so-called sink mark from the opening side of the recess 21 toward the bottom surface 211 side. For this reason, if the irregularities 81 and 82 were formed up to the opening edge 213 of the recess 21, sink marks would occur in the resin 90, exposing the surfaces of the protrusions 82 and impairing the appearance and feel.

[0066] In contrast to this, in this embodiment, the irregularities 81 and 82 are provided closer to the bottom surface 211 than the opening edge 213, so even if a sink mark occurs, the surface of the protrusion 82 can be prevented from being exposed, and the appearance and feel can be maintained.

[0067] <<Modification of the Second Embodiment>> In the second embodiment, each of the pair of longitudinal side surfaces 212a has a plurality of irregularities 81, 82, but it is also possible for only one of the longitudinal side surfaces 212a to have a plurality of irregularities 81, 82.

[0068] In the second embodiment, the resin 90 is poured into the recess 21 and hardened, but the recess 21 may be closed with a lid. In this case, the resin 90 may or may not be used.

[0069] Furthermore, the plurality of irregularities 81, 82 may be provided not only on the longitudinal side surfaces 212a but also on the lateral side surfaces 212b or the bottom surface 211.

[0070] <<Other embodiments>> The present invention is not limited to the above-described embodiments.

[0071] In the above embodiment, the electronic tag 40 is provided on only one of the gripping parts 30, but as shown in FIG. 10, it may be provided on each of the gripping parts 30.

[0072] Furthermore, in the above embodiment, the electronic tag 40 was provided inside the inside of the grip portion 30, but it may also be provided inside the outside of the grip portion 30, i.e., inside the part that the operator's palm touches.

[0073] In addition, in the above embodiment, pliers are used as the tool 100, but the tool 100 of the present invention may be a pair of scissors as shown in FIG. 11 or nippers (not shown) as long as it has a pair of rotatably connected gripping portions 30, and these tools 100 also have an electronic tag 40 provided inside one or both of the gripping portions 30.
