Description

[Technical Field]

[0001] The present invention relates to a flexible sheet and a tank bag that can be attached to a flat or uneven surface of an object, particularly to an oil tank of a saddle-type vehicle or to a part of the vehicle corresponding to the position of the oil tank. [Background technology]

[0002] In the past, oil tanks for saddle-type vehicles such as motorcycles and three-wheeled vehicles were often made of steel, but in recent years, many saddle-type vehicles have begun to use tanks made of materials other than steel, such as synthetic resin covers for the oil tank or aluminum tanks.

[0003] Tank bags manufactured and sold for steel oil tanks to store small items such as maps, navigation systems, mobile devices, and wallets have a magnet attached to the mounting strap, which allows the bag to be firmly attached to the steel tank with magnetic force. This allows the bag to be attached and detached freely, yet firmly fixed to the tank.

[0004] It is known that an adhesive member for attracting magnet pieces, which is used in combination with a magnet piece to allow posters and the like to be attached, has a protective layer laminated and integrated onto the front side of the iron plate piece, and a buffer layer, adhesive layer, and release sheet laminated and integrated onto the back side in this order (see Patent Document 1).

[0005] It is also known that in a board, a bendable writing layer is provided on the surface side of a bendable base material such as acrylic foam or urethane foam, a magnetic material that can attract a magnet on the surface side of the writing layer is interposed between the base material and the writing layer, and the hard magnetic material is divided into multiple pieces and scattered at intervals from each other, allowing the whiteboard that can attract magnets to be rolled up into a small roll (see Patent Document 2).

[0006] Furthermore, it is disclosed in a blog post that reads, "I've been thinking about buying one for a while and have been to the Nankai Parts Sendai store several times, but the tank bag support is always sold out, so I finally managed to get one, and I'll write about how easy it is to use. MBS-1011 Mag Bag Support Black (there seem to be other colors too). It's a sticker with metal in it that allows you to attach a tank bag magnet to the plastic tank part" (Non-patent document 1, etc.). [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Patent No. 6755668 [Patent Document 2] Japanese Patent Application Laid-Open No. 2008-1079 [Non-patent literature]

[0008] [Non-Patent Document 1] Blog post "Haineko Z1000 Blog," blog title "Nankai Parts Tank Bag Support," November 18, 2015, z1000-2012.cocolog-nifty.com / blog / 2015 / 11 / post-19bd.html Summary of the Invention [Problem to be solved by the invention]

[0009] However, tank bags that are manufactured and sold for iron tanks and have magnets in the mounting belt cannot be attached to tanks with synthetic resin covers as they are.

[0010] In such a case, if an adhesive member for attracting magnetic pieces containing an iron plate, such as that shown in Patent Document 1, is used and attached to a tank with a synthetic resin cover, there are problems with the flexibility and durability of the member when it is attached to the surface of a three-dimensional object that has a curved shape rather than a flat shape, such as an oil tank for a motorcycle or the like.

[0011] Furthermore, in the example board shown in Patent Document 2, although the base material is flexible, the magnetic material is made of a thin plate, so the magnetic force is not strong and it is not suitable for securing heavy objects such as tank bags.

[0012] FIG. 20 shows an example of a conventional flexible sheet 100. As described in Non-Patent Document 1, for example, when a product named "Mag Bag Support" (Nankai Parts Co., Ltd., Model No. MBS-1011) obtained by the applicant is disassembled, the structure is as shown in FIG. 20(a) (plan view), (b) (front view), and (c) (enlarged exploded view of Ery-Ert). Specifically, the flexible sheet 100 shown in FIG. 20 has a synthetic resin rubber sheet 101 provided with a magnetized region 400 containing, for example, a plurality of magnetizable spherical iron balls 410. The adhesive layer 102 can be attached to the tank of a plastic cover of a motorcycle or other two-wheeled motor vehicle.

[0013] However, although the flexible sheet 100 such as the example shown in Figure 20 is thin and flexible, it can be seen from Non-Patent Document 1 that the magnetized region 400 containing multiple small spherical iron balls 410 does not have enough magnetic force to firmly secure a tank bag carrying a heavy object.

[0014] As explained above, flexible sheets made of materials such as non-magnetizable resin that can be attached to flat or uneven surfaces of objects to which magnets cannot be attached are available on the market, but there are several issues with these.

[0015] Therefore, the problem that the present invention aims to solve is to provide a flexible sheet that can be flexibly attached to a flat or uneven surface of an object having a flat or uneven surface, in particular to the oil tank of a saddle-ride type vehicle or a part of the vehicle corresponding to the position of the oil tank, and that can strongly attract a magnet to the part to which it is attached, and a tank bag for a saddle-ride type vehicle that can utilize this flexible sheet. [Means for solving the problem]

[0016] To solve the above problems, the present invention provides a flexible sheet that can be attached to a flat or uneven surface of an object having a flat or uneven shape, the flexible sheet comprising: one or more ferromagnetic plates; a plate-containing portion that entirely contains the one or more ferromagnetic plates in a layer made of a flexible synthetic resin material with a thickness greater than that of the one or more ferromagnetic plates; and one or more flap portions made of the synthetic resin material, the flap portions being connected to one surface of the plate-containing portion in the thickness direction across a groove formed with a bendable concave structure on one surface side of the plate-containing portion, and the flap portions being connected to the other surface side of the plate-containing portion in the thickness direction with the same horizontal plane, and an adhesive layer is provided on the other surface side of the plate-containing portion in the thickness direction. In order to solve the above-mentioned problems, the present invention provides a tank bag for a saddle-ride type vehicle that is attached to an oil tank of the saddle-ride type vehicle or to a vehicle part corresponding to the position of the oil tank, the tank bag comprising a plurality of mounting belts and a plurality of the flexible sheets, each of which has a magnet attached to it, so that when the flexible sheets are attached to the oil tank of the saddle-ride type vehicle or to a vehicle part corresponding to the position of the oil tank, each of the magnets attached to the mounting belts of the flexible sheets can be attached to the one or more ferromagnetic plates included in the plate-containing portion. [Effects of the Invention]

[0017] The flexible sheet according to the present invention can be flexibly attached to a flat or uneven surface of an object, particularly to an oil tank of a saddle-ride type vehicle or a portion of the vehicle corresponding to the position of the oil tank, and a magnet can be strongly attracted to the attached portion.Furthermore, the tank bag according to the present invention can be used when attached to an oil tank of a saddle-ride type vehicle or a portion of the vehicle corresponding to the position of the oil tank.

[0019] Flexible seats and tank bags according to embodiments of the present invention will be described in detail below with reference to the drawings. Here, identical or similar parts will be designated by common reference numerals, and duplicate explanations will be omitted. All of the following embodiments will be described by taking as an example a flexible seat and tank bag used primarily in saddle-ride vehicles such as motorcycles and tricycles. It should be noted that the present invention is not limited to saddle-ride vehicles, and can also be applied to flat or curved objects.

[0020] [First embodiment] The configuration of a first embodiment of a flexible sheet 1A according to the present invention will be described below with reference to FIGS. 1 to 12. FIG. 1 shows an example of the structure of a first embodiment of a flexible sheet 1A according to the present invention, with FIG. 1(a) being a plan view of the flexible sheet 1A and FIG. 1(b) being a vertical cross-sectional view taken along the line II in FIG. 1(a). FIG. 2 shows an example of the structure of the flexible sheet 1A of the first embodiment, following FIG. 1, with FIG. 2(a) being a plan view, FIG. 2(b) being a front view, FIG. 2(c) being a bottom view, and FIG. 2(d) being a right side view. The other figures will be described later as appropriate.

[0021] The flexible sheet 1A of the first embodiment can be attached to a flat or uneven surface of an object having a flat or uneven surface. The flexible sheet 1A is composed of an iron plate 4A, an iron plate containing portion 2A, and multiple flap portions 3A.

[0022] The iron plate containing portion 2A has a thickness t of the iron plate 4A shown in FIG. ir A layer thicker than th The iron plate 4A is entirely covered with a flexible synthetic resin material (for example, elastomer). The iron plate 4A is not limited to iron, and any ferromagnetic material, such as cobalt or nickel, may be used.

[0023] The plurality of flap portions 3A (flap portions 31a, 32a, 33a, and 34a) are attachment members made of a flexible synthetic resin material such as elastomer for reinforcing the attachment of the iron plate containing portion 2A.

[0024] The groove directions of the grooves 11a, 13a, 15a, and 17a are formed along the peripheral contour of the iron plate containing portion 2A. The iron plate containing portion 2A and each of the flap portions 31a, 32a, 33a, and 34a are connected on one surface 21a (hereinafter simply referred to as the surface 21a) side of the iron plate containing portion 2A, with the grooves 11a, 13a, 15a, and 17a formed as bendable concave structures as boundaries. Furthermore, as shown in FIG. 6, the thickness t thdw is a thickness t of the iron plate containing portion 2A so that a concave structure is formed on one surface 21a side in the thickness direction of the iron plate containing portion 2A. th It is formed with a thickness thinner than

[0025] The iron plate containing portion 2A and each of the flap portions 31a, 32a, 33a, and 34a are connected to the other surface 10a of the iron plate containing portion 2A in the thickness direction, with the horizontal planes being the same. An adhesive layer (not shown) is provided on the other surface 10a of the iron plate containing portion 2A in the thickness direction.

[0026] In the case of multiple flap portions 3A, when adjacent flap portions 31a and 33a, and flap portions 32a and 34a have different groove directions, adjacent flap portions 31a and 33a are separated by separation path 19a, and adjacent flap portions 32a and 34a are separated by separation path 110a.

[0027] As shown in Figures 1, 2 and 6, within the flap portions 31a, 32a, 33a and 34a, one or more flap groove portions 12a, 14a, 16a and 18a are further formed on one surface 21a side with a thickness thinner than the thickness of the iron plate containing portion 2A and with a concave structure that can be bent and deformed.

[0028] The thickness of the sheet from the flap surfaces 311a and 312a to the back surface 10a may be the same as or thinner than the thickness of the iron plate-containing portion 2A. The same applies to the thickness from the flap surfaces 321a and 322a to the back surface 10a, from the flap surfaces 331a and 332a to the back surface 10a, and from the flap surfaces 341a and 342a to the back surface 10a.

[0029] 1 and 2, in the plurality of flap portions 3A, the groove directions of the groove portions 11a and 15a are different between adjacent flap portions 31a and 33a, and the groove directions of the groove portions 13a and 17a are different between adjacent flap portions 32a and 34a. For example, the adjacent flap portions 31a and 33a are separated by a separation path 19a. The adjacent flap portions 32a and 34a are separated by a separation path 110a.

[0030] Here, Fig. 3 is a diagram showing an example of attachment of the flexible sheet 1A of the first embodiment. Fig. 4 is a diagram illustrating an attachment state of the flexible sheet 1A of the first embodiment on an uneven surface. Fig. 5 is a diagram illustrating an example of a case where a tank bag 5A is attached to an oil tank 9 of a motorcycle using the flexible sheet 1A of the first embodiment. Fig. 6 is a diagram illustrating an example of the shape of the flexible sheet 1A of the first embodiment in the thickness direction.

[0031] As an example, the prototype of flexible sheet 1A shown in Figures 3 and 5 allows a tank bag 5A with magnets encapsulated in mounting belts 51 and 52 to be attached to an oil tank 9 with a synthetic resin cover of a motorcycle, for example, as shown in Figure 5. The prototype of flexible sheet 1A is made of an elastic elastomer. In particular, it has the following features to make it easy to attach to the uneven surfaces of three-dimensional objects.

[0032] 3 and 4 show the flexible sheet 1A attached to, for example, an oil tank 9 of a synthetic resin cover for a motorcycle as an object with a concave-convex surface. The broken lines in Fig. 4 show an outline of the concave-convex surface formed by a vertical ridge shape FLud and a front-rear ridge shape FLfr on the side surface of the oil tank 9.

[0033] In the flexible sheet 1A, the groove directions of the groove portions 11a, 13a, 15a and 17a are formed along the peripheral contour of the iron plate containing portion 2A, so that each of the flap portions 31a, 32a, 33a and 34a can be bent with each groove direction as the bending axis.

[0034] For example, in the state where flexible sheet 1A is attached to an object with an uneven surface as shown in Fig. 4, iron plate containing portion 2A contains hard iron plate 4A, so that the back surface 10a side of iron plate containing portion 2A becomes a nearly flat attached portion. Therefore, attention point Pta shown by the circular dashed line in Fig. 4 is the area around iron plate containing portion 2A where a gap is likely to form between the flexible sheet 1A and the object with an uneven surface when attached to the object.

[0035] Therefore, in the flexible sheet 1A of the first embodiment, groove portions 11a, 13a, 15a, and 17a are formed around the iron plate containing portion 2A with a bendable and deformable concave structure, and flap portions 31a, 32a, 33a, and 34a are formed in multiple flap portions 3A with the groove portions 11a, 13a, 15a, and 17a as boundaries.

[0036] For example, in the iron plate containing portion 2A shown in Figure 4, since the iron plate 4A is approximately rectangular in shape, flap portions 31a, 32a, 33a, and 34a are connected to opposite sides of the four sides along the outer periphery of the approximately rectangular shape of the iron plate 4A, thereby reducing the occurrence of gaps.

[0037] On one surface 21a of the iron plate containing portion 2A in the thickness direction, groove portions 11a, 13a, 15a and 17a are formed with a bendable concave structure and have a thickness thinner than the thickness of the iron plate containing portion 2A. On the other surface (rear surface 10a) of the iron plate containing portion 2A in the thickness direction, multiple flap portions 31a, 32a, 33a and 34a are connected, with the same horizontal plane, to the other surface (rear surface 10a) of the iron plate containing portion 2A.

[0038] In the iron plate containing portion 2A including the iron plate 4A, grooves 11a, 13a, 15a, and 17a are formed on the surface side of the peripheral portion that follows the peripheral shape of the iron plate 4A. These grooves 11a, 13a, 15a, and 17a form boundaries along the grooves with the flap portion 3A.

[0039] The peripheral portion of the steel plate 4A that conforms to the peripheral shape preferably has grooves extending in four directions. For example, grooves extending in the four directions indicated by the dashed lines in Figure 4. In addition, by providing slits or portions that are not connected to the flap portions 31a, 32a, 33a, and 34a at the boundaries in different directions, a polygonal bent structure can be formed so that the adhesive surfaces are more closely in contact with each other, for example, along different uneven surfaces.

[0040] Since the iron plate containing portion 2A is a rubber sheet containing an iron plate 4A, the iron plate containing portion 2A is difficult to bend. Therefore, by forming groove portions 11a, 13a, 15a and 17a at the boundaries between the iron plate containing portion 2A and the flap portions 31a, 32a, 33a and 34a, the sheet can be easily bent to the opposite side from the front surface side.

[0041] The tank bag 5A for a saddle-ride type vehicle shown in Fig. 5(a) can normally be attached to an iron oil tank of a saddle-ride type vehicle as is because the tank bag 5A has magnets mounted on each of the multiple mounting belts 51 and 52. However, if the saddle-ride type vehicle shown in Fig. 5(a) has an oil tank 9 with a synthetic resin cover, the tank bag 5A cannot be attached to the oil tank 9 with a synthetic resin cover as is.

[0042] Therefore, as shown in Fig. 5(a), flexible sheets 1A are attached to an oil tank 9 with a synthetic resin cover at two locations on the left and right of a rear side surface 92 on both side surfaces 93 closer to the rear tank surface 91 of the oil tank 9, and at two locations on the left and right of a front side surface 94 on both side surfaces 93. Then, as shown in Fig. 5(b), a storage case 50 is placed on the top surface 95 of the oil tank 9 so as to mount a tank bag 5A thereon, and magnets mounted on the multiple mounting belts 51 and 52 allow each of the multiple flexible sheets 1A to be attached to the iron plate 4A contained in the iron plate containing portion 2A.

[0043] Here, we will explain the details of an example of the shape in the thickness direction of the flexible sheet 1A of the first embodiment shown in Figure 6. Figure 6(a) is an enlarged view of the vertical cross section in the direction of the arrow II shown in Figure 1(a) shown in Figure 1(b), Figure 6(b) is an enlarged view of the left end side on the paper surface of Figure 6(a), and Figure 6(c) is an enlarged view of the inclusion layer of the iron plate 4A in Figure 6(a).

[0044] 6(a) and 6(b), the thickness th of the flexible sheet 1A in the thickness direction, the depth t of the grooves 13a and 15a, and the depth t of the flap groove 16a thup , and the thickness of those grooves t thdw , groove opening width t w , 1st groove slope width t r , groove bottom width t c , 2nd groove slope width t l In addition, in FIG. 6(c), the thickness t of the iron plate 4A in the thickness direction of the flexible sheet 1A is ir , the thickness t of the upper layer of the steel plate containing portion 2A up , the thickness of the lower layer of the steel plate containing part 2A t dw This shows:

[0045] As shown in FIGS. 6(a) to 6(c), the thickness t thdw , the thickness t of the bottom surface of the flap grooves 12a, 14a, 16a and 18a thdw The thickness t of the iron plate containing portion 2A is measured on one surface 21a side of the iron plate containing portion 2A in the thickness direction.th It can be seen that the thickness of the recessed groove is thinner than that of the recessed groove.

[0046] 6(a) has a structure in which the thickness of the flap portion 31a is thinner on the edge side or is inclined downward on the edge side, etc. For example, when the flexible sheet 1A is attached to an oil tank 9 or the like, not only is the repulsive force of the sheet on the edge side suppressed, but the following advantages are also achieved.

[0047] For example, in order to make the end less likely to come off when a tank bag or the like is attached to the oil tank 9 or when it hits clothing or the like when the driver gets in or out of the car, and to reduce the frequency of collisions with these objects at the end, the thickness of the flap portion 31a is made thinner than the plate thickness portion other than the flap groove portion 12a.

[0048] Fig. 7 is a diagram showing (b) a cut flexible sheet 1Ab of an example obtained by cutting (a) the flexible sheet 1A of the first embodiment along chain lines II and III. Fig. 8 is a diagram showing the flexible sheet 1A shown in Fig. 7(a) and the cut flexible sheet 1Ab of Fig. 7(b) attached to an oil tank 9 of a motorcycle.

[0049] In Fig. 7(a), the flexible sheet 1A of the first embodiment is cut along chain line II along the flap grooves 12a and 16a and also cut along chain line III along the flap grooves 14a and 18a to obtain a cut flexible sheet 1Ab shown in Fig. 7(b). In the cut flexible sheet 1Ab, as shown in Fig. 7(b), flap portions 31ab, 32ab, 33ab, and 34ab are cut from the flap grooves 12a, 14a, 16a, and 18a to the ends of the original flap portions 31a, 32a, 33a, and 34a.

[0050] Figure 8 shows an oil tank 9, a synthetic resin cover located on the rear side of a handlebar 81 of a motorcycle handlebar 8A, with cut flexible sheets 1Ab attached to two locations on the left and right of a rear side surface 92 on both side surfaces 93 closer to the rear tank surface 91 of the oil tank 9, and flexible sheets 1A attached to two locations on the left and right of a front side surface 94 on both side surfaces 93.

[0051] With the flexible sheet 1A and the cut flexible sheet 1Ab attached in this manner, the tank bag 5A can be placed over the oil cap 96 on the upper surface 95 of the oil tank 9, and the magnets mounted on the multiple mounting belts 51 and 52 of the tank bag 5A can be used to firmly attach each of the multiple flexible sheets 1A and cut flexible sheets 1Ab to the iron plate 4A contained in the iron plate containing portion 2A.

[0052] Fig. 9 is an image showing a prototype of the flexible sheet 1A corresponding to the first embodiment, and Fig. 10 is an explanatory image showing the state in which the bendability of the prototype is being tested. Also, Fig. 11 and Fig. 12 are images showing an example of the prototype attached to an oil tank with a synthetic resin cover of a motorcycle, and an example of the state in which a tank bag is attached to the oil tank with a synthetic resin cover.

[0053] As an example, for example, in the prototype of flexible sheet 1A shown in Figures 9 and 10, flexible sheet 1A is an elastic sheet (a sheet with adhesive on the back and iron plate 4A enclosed within the elastic sheet) that is mainly used to attach tank bag 5A (corresponding to Figure 5) with magnets enclosed in mounting belts 51 and 52 to oil tank 9 (corresponding to Figures 3 and 5) of a synthetic resin cover of a motorcycle shown in Figures 11 and 12. In particular, it has the following features to make it easy to attach to the uneven surface of a three-dimensional object.

[0054] The resin encapsulating the iron plate 4A is formed as an encapsulation layer in the iron plate containing portion 2A that is thicker than the iron plate 4A. Flap portions 31a, 32a, 33a, and 34a are provided along the periphery of the encapsulation area of ​​the iron plate containing portion 2A, and one or more flap groove portions 12a, 14a, 16a, and 18a are further formed in the flap portions 31a, 32a, 33a, and 34a.

[0055] For example, as a manufacturing method of the flexible sheet 1A, an iron plate 4A is enclosed by insert molding, and the iron plate 4A is surrounded by elastomer to form the characteristic shape as described above, which has the following excellent features. - Flexible sheet with excellent flexibility even when it contains thick steel plates Flexible sheet with strong magnetic fixation

[0056] In the flexible sheet 1A, the iron plate 4A, which is approximately square in plan view as shown in, for example, Figures 1 and 2, is arranged so that the entire iron plate is enclosed by an iron plate containing portion 2A made of a flexible synthetic resin material in a layer thicker than the thickness of the iron plate 4A in the vertical direction (the plan view direction in Figure 2(a) is the upward direction) and in the peripheral direction of the side. As an example, the thickness t ir However, the thickness t of the iron plate 4A can be set to about 2 mm. ir is not limited to this.

[0057] The prototype images shown in Figures 11 and 12 are of a rubber sheet (a specially shaped rubber sheet with adhesive on the back and an iron plate enclosed within) that allows a tank bag with a magnet enclosed in a mounting belt to be attached to a synthetic resin tank cover for motorcycles. The rubber sheet is made of a synthetic resin with excellent elasticity, such as elastomer.

[0058] Furthermore, for example, the design values ​​of the flexible sheet 1A of the prototype shown in FIGS. 9 to 12 are, in accordance with the parameters shown in FIG. 6, the sheet thickness th=4 mm, the groove depth t thup = 2 mm, groove thickness tthdw =2mm, groove opening width t w =4.5mm, 1st groove slope width t r =1.5mm, groove bottom width t c =1.5mm, 2nd groove slope width t l =1.5mm, opening angle α w = 135 degrees. Also, the thickness of the steel plate 4A is t ir = 2 mm, thickness of the upper layer containing the steel plate t up = 1 mm, thickness of the steel plate-containing lower layer t dw The overall dimensions of the flexible sheet 1A are calculated based on the sheet width t ya =112mm, sheet length t ta = 47 mm, and the dimensions of the iron plate 4A are length and width = 30 mm.

[0059] In the flexible sheet 1A of the prototype shown in FIGS. 9 to 12, the recessed structure of the groove portion is trapezoidal, and the opening angle α w =135 degrees. It was confirmed that the groove portion and the flap groove portion could be folded sufficiently to follow when folded toward the rear surface 10a, as shown in FIG.

[0060] The flexible sheet 1A of this embodiment has a concave structure with excellent flexibility, and the sheet can be made thick, allowing a thick steel plate to be used as the magnetic body. This allows the magnetic force of the flexible sheet 1A to be strong, making it possible to secure heavy objects such as tank bags. For example, a tank bag weighs about 1 kg without cargo and about 1 to 5 kg when loaded. However, the flexible sheet 1A attached to the oil tank with a resin cover allows the tank bag to be firmly secured.

[0061] In this embodiment, the iron plate 4A is a single flat plate, but it may contain multiple iron plates. For example, multiple rectangular iron plates may be arranged in a substantially square shape, and the multiple iron plates arranged in the substantially square shape may be contained in the iron plate containing portion 2A.

[0062] The sheet has a plurality of recessed grooves to reduce the repulsive force of the entire sheet, even when attached to a curved surface such as the oil tank 9 of a motorcycle synthetic resin cover. This allows the adhesive surfaces of the flap portions 31a, 32a, 33a, and 34a around the adhesive layer on the back side of the iron plate inclusion portion 2A to adhere to the curved surface such as the oil tank 9 with less repulsive force, even in a bent state. This prevents the adhesive surface of the adhesive layer of the iron plate inclusion portion 2A from peeling off from the curved surface such as the oil tank 9.

[0063] The flexible sheet of this embodiment can be flexibly attached to a flat or uneven surface of an object, particularly to an oil tank of a saddle-ride type vehicle or a portion of the vehicle corresponding to the position of the oil tank, and a magnet can be strongly attracted to the attached portion. Also, the tank bag of this embodiment can be used when attached to an oil tank of a saddle-ride type vehicle or a portion of the vehicle corresponding to the position of the oil tank.

[0064] [Second embodiment] Figures 13 to 15 are explanatory diagrams of the groove shape and groove opening angle. Figure 13 is a diagram showing an example of the groove shape of a flexible sheet of another embodiment. Also, Figure 14 is a diagram showing an example of the groove structure of a flexible sheet of another embodiment, and Figure 15 is a diagram explaining an outline of the degree of flexibility of a flexible sheet of another embodiment.

[0065] In Figure 13, the groove shapes in the vertical cross section of the sheet thickness of grooves 11a, 13a, 15a and 17a of the iron plate containing portion 2A, flap groove 12a of flap portion 31a, flap groove 14a of flap portion 32a, flap groove 16a of flap portion 33a, and flap groove 18a of flap portion 34a, for example, include a rectangular shape as shown in Figure 13(a), a trapezoidal shape as shown in Figure 13(b), a narrow-angled triangular shape as shown in Figure 13(c), and a wide-angled triangular shape as shown in Figure 13(d).

[0066] In the rectangular groove shape shown in FIG. 13(a), the opening angle α v = 90 degrees, and in the trapezoidal groove shape shown in FIG. 13(b), the opening angle α w In addition, in the triangular groove shape shown in FIG. 13(c), the opening angle α u1 = 60 degrees, and in the triangular groove shape shown in FIG. 13(c), the opening angle α u2 13(c) and 13(d) are also called V-grooves.

[0067] For example, the V-groove grooves shown in Figures 13(c) and (d) have a greater ability to return to their original shape when bent than the grooves with a groove bottom as shown in Figures 13(a) and (b), and are therefore less flexible at any angle.

[0068] On the other hand, grooves with a groove bottom, such as those shown in Figures 13(a) and (b), can be bent over the entire bottom surface, resulting in excellent flexibility. Furthermore, by reducing the thickness of the bottom surface (=ta-tf), flexibility can be further improved. However, if the thickness of the bottom surface (=ta-tf) is made too thin, the sheet may be prone to tearing or breakage at the grooves, resulting in poor durability of the flexible sheet. Note that ta is the sheet thickness, and tf is the depth of the groove.

[0069] FIG. 14 is a diagram showing an example of a groove structure of a flexible sheet according to another embodiment. The flap portion 31a shown in FIG. 1(a) corresponds to the flap portion 31a shown in FIG. 1 and other figures, and shows the groove portion 11a, flap groove portion 12a, and flap surfaces 311a and 312a shown in FIG. 1 and other figures. The groove shape shown in FIG. 14(b) (a longitudinal cross-sectional view taken along the arrow IV in FIG. 14(a)) corresponds to the trapezoidal groove shape shown in FIG. 13(b), for example. Meanwhile, the flap portion 31u shown in FIG. 14(d) shows the groove portion 11u, flap groove portion 12a, and flap surfaces 311u and 312u. The groove shape shown in FIG. 14(e) (a longitudinal cross-sectional view taken along the arrow V in FIG. 14(d)) corresponds to the wide-angle triangular groove shape shown in FIG. 13(d), for example.

[0070] The trapezoidal groove structure (opening angle α w ) in the direction of the arrow in the figure is the bent state of the trapezoidal groove structure shown in FIG. 14(c). Also, the triangular groove structure (opening angle α u ) in the direction of the arrow in the figure shows the bent state of the triangular groove structure shown in Figure 14(f). In other words, this shows that the bendability of the trapezoidal groove structure shown in Figure 14(c) is superior to the bendability of the triangular groove portion shown in Figure 14(f).

[0071] FIG. 15 is a diagram illustrating the degree of flexibility of a flexible sheet according to another embodiment. The rectangular groove shape shown in FIG. 15(a) has an opening angle of αv, and the trapezoidal groove shape shown in FIG. 15(b) has an opening angle of α w In the rectangular groove shape shown in FIG. 15(a), the opening angle α v The flexibility of the flexible sheet in the direction of widening the groove is shown in FIG. 15(c). On the other hand, the opening angle α w The flexibility of the flexible sheet in the direction of spreading is shown in FIG. 15(d).

[0072] In addition, in the rectangular groove shape shown in FIG. 15(a), the opening angle α vThe bending property of the flexible sheet in the direction of narrowing the opening angle α in the trapezoidal groove shape shown in FIG. w The flexibility of the flexible sheet in the direction of narrowing is shown in Figure 15(f), where ta is the sheet thickness and tf is the groove depth.

[0073] For example, when the opening angle αv is set to about 90 degrees, in the prototype example, by bending the entire bottom surface, it is possible to bend the displacement range up to Figures 15(c) and (d) with a displacement of about 60 degrees on one side.

[0074] Also, for example, the opening angle α w = 135 degrees, the entire bottom surface is bent in the prototype, and the displacement range up to Fig. 15(d) and (f) is v = 90 degrees, for example, it can be bent with a displacement of about 90 degrees on one side. If the thickness of the base (thickness equivalent to = ta - tf) is made thinner, it can be bent with a greater displacement.

[0075] Preferably, the groove shape of the groove portion and the flap groove portion is substantially trapezoidal, and the opening angle of the opening side is greater than 90 degrees and smaller than 180 degrees.

[0076] The flexible sheet of this embodiment can be flexibly attached to the flat or uneven surface of an object having a flat or uneven surface, particularly to the oil tank of a saddle-type vehicle or a part of the vehicle corresponding to the position of the oil tank, and can strongly attract a magnet to the attached part.

[0077] [Third embodiment] Fig. 16 is a diagram showing an example of the structure of flexible sheet 1B of the third embodiment. As an example of the structure of flexible sheet 1B of Fig. 16, Fig. 16(a) is a plan view, Fig. 16(b) is a vertical cross-sectional view taken along the line VI-VI in Fig. 16(a), Fig. 16(c) is an enlarged view of flap portion 31b shown in Fig. 16(a), and Fig. 16(d) is a perspective view of flap portion 31b in Fig. 16(c).

[0078] The flexible sheet 1B of the third embodiment can be attached to a flat or uneven surface of an object having a flat or uneven surface. The flexible sheet 1B is composed of an iron plate 4B, an iron plate containing portion 2B, and a plurality of flap portions 3B.

[0079] In the flexible sheet 1B, groove portions 11b, 15b, 19b, and 113b are formed around the iron plate containing portion 2B with a bendable and deformable concave structure, and flap portions 31b, 32b, 33b, and 34b are formed in multiple flap portions 3B with the groove portions 11b, 15b, 19b, and 113b as boundaries.

[0080] The iron plate containing portion 2B is a layer thicker than the iron plate 4B, and the entire iron plate is made of a flexible synthetic resin (elastomer) material. The multiple flap portions 31b, 32b, 33b, and 34b are adhesive members made of a flexible synthetic resin material such as elastomer to reinforce the attachment of the iron plate containing portion 2B.

[0081] The iron plate containing portion 2B and each of the flap portions 31b, 32b, 33b, and 34b are connected on one surface 21b side of the iron plate containing portion 2B by groove portions 11b, 15b, 19b, and 113b formed with a bendable concave structure. Furthermore, the thickness of the groove portions 11b, 15b, 19b, and 113b is formed to be thinner than the thickness of the iron plate containing portion 2B on one surface 21b side in the thickness direction of the iron plate containing portion 2B.

[0082] The iron plate containing portion 2B and each of the flap portions 31b, 32b, 33b, and 34b are connected to the other surface 10b of the iron plate containing portion 2B in the thickness direction, with the horizontal planes being the same. An adhesive layer (not shown) is provided on the other surface 10b of the iron plate containing portion 2B in the thickness direction.

[0083] Within the flap portion 31b, there are further formed a plurality of flap groove portions 12b, 13b and 14b on one surface 21b side, which have a thickness thinner than the thickness of the iron plate containing portion 2B and are formed with a concave structure that can be bent and deformed.

[0084] Furthermore, in the flap portion 32b, a plurality of flap grooves 16b, 17b, and 18b are formed on one surface 21b side with a thickness thinner than that of the steel plate containing portion 2B and formed with a bendable concave structure. Similarly, in the flap portion 33b, a plurality of flap grooves 110b, 111b, and 112b are formed, and similarly, in the flap portion 34b, a plurality of flap grooves 114b, 115b, and 116b are formed.

[0085] The thickness of the sheet from the flap surfaces 311b to 314b to the back surface 10b may be the same as or thinner than the thickness of the iron plate-containing portion 2B. The same applies to the thickness from the flap surfaces 321b to 324b to the back surface 10b, from the flap surfaces 331b to 334b ​​to the back surface 10b, and from the flap surfaces 341b to 344b to the back surface 10b.

[0086] If the central iron plate 4B is circular as shown in Figures 16(a) and 16(b), when attaching the flexible sheet 1B to a curved surface of a three-dimensional object, dead space is required between the grooves 11b, 15b, 19b, and 113b of the flap portions 31b, 32b, 33b, and 34b and the circular periphery of the iron plate containing portion 2B. For this reason, it is necessary to leave a certain amount of space Ptb at the bent portion, as shown in Figures 16(c) and 16(d), for example.

[0087] When the flexible sheet 1B is attached to the three-dimensional curved surface of the object, gaps tend to form around the outer periphery of the steel plate containing portion 2B. Therefore, the flaps 31b, 32b, 33b, and 34b reduce the area where the gaps are formed and reinforce the adhesive surface so as to cover the outer periphery of the steel plate containing portion 2B. On the other hand, gaps tend to form around the outer periphery of the steel plate containing portion 2B other than the connection areas of the flaps 31b, 32b, 33b, and 34b.

[0088] Here, Fig. 17 shows a comparative example between the flexible sheet 1B of the third embodiment and the flexible sheet 1A of the first embodiment. Specifically, Fig. 17(a) shows a plan view of the iron plate 4A of the flexible sheet 1A of the first embodiment, Fig. 17(b) shows a plan view of the iron plate 4B of the flexible sheet 1B of the third embodiment, and Fig. 17(c) shows a comparative plan view of the iron plate 4A and the iron plate 4B.

[0089] For example, when attached to an object with an uneven surface such as an oil tank 9 of a motorcycle or the like as shown in Figures 3 and 4, the flexible sheet 1A of the first embodiment can reduce the gap between the object and the uneven surface as shown by the caution point Pta indicated by the dashed circle in Figure 4, compared to the flexible sheet 1B of the third embodiment. In other words, when attached to an object with an uneven surface such as an oil tank 9 of a motorcycle or the like as shown in Figures 3 and 4, the flexible sheet 1A of the first embodiment has a more preferable shape.

[0090] Also, for example, the iron plate 4A (length x width t iw ) and iron plate 4B (diameter t iw ) and have the same external dimensions, the square-shaped iron plate 4A has a wider effective area range for the magnets (for example, circular) enclosed in the mounting belts 51 and 52 on the tank bag 5A side as shown in FIG. 5, so when attaching it with the mounting belts 51 and 52, the mounting area on the iron plate side is wider, making it easier to attach the magnet side.

[0091] The flexible sheet of this embodiment has a concave structure with excellent flexibility, and the thickness of the sheet can be increased, so a thick iron plate can be used as the magnetic body, thereby increasing the magnetic force of the flexible sheet.

[0092] The flexible sheet of this embodiment can be flexibly attached to a flat or uneven surface of an object, particularly to an oil tank of a saddle-ride type vehicle or a portion of the vehicle corresponding to the position of the oil tank, and a magnet can be strongly attracted to the attached portion. Also, the tank bag of this embodiment can be used when attached to an oil tank of a saddle-ride type vehicle or a portion of the vehicle corresponding to the position of the oil tank.

[0093] [Fourth embodiment] Fig. 18 shows an example of the structure of a flexible sheet 1C of the fourth embodiment, with Fig. 18(a) being a plan view of the flexible sheet 1C and Fig. 18(b) being a longitudinal sectional view taken along the line VII-VII in Fig. 18(a). Fig. 19 shows a plan view of the flexible sheet 1C of the fourth embodiment in Fig. 19(a) and a comparative example to the flexible sheet 1A of the first embodiment in Fig. 19(b).

[0094] The flexible sheet 1C of the fourth embodiment can be attached to a flat or uneven surface of an object having a flat or uneven surface. The flexible sheet 1C is composed of an iron plate 4C, an iron plate containing portion 2C, and a plurality of flap portions 3C.

[0095] In the flexible sheet 1C, groove portions 11c, 15c, 19c, and 113c are formed around the iron plate containing portion 2C with a bendable and deformable concave structure, and flap portions 31c, 32c, 33c, and 34c are formed in multiple flap portions 3C with the groove portions 11c, 15c, 19c, and 113c as boundaries.

[0096] The iron plate containing portion 2C is a layer thicker than the iron plate 4C, and the entire iron plate is made of a flexible synthetic resin (elastomer) material. The multiple flap portions 31c, 32c, 33c, and 34c are adhesive members made of a flexible synthetic resin material such as elastomer to reinforce the attachment of the iron plate containing portion 2C.

[0097] The steel plate containing portion 2C and each of the flap portions 31c, 32c, 33c, and 34c are connected on one surface 21c side of the steel plate containing portion 2C by groove portions 11c, 15c, 19c, and 113c formed with a bendable concave structure. Furthermore, the thickness of the groove portions 11c, 15c, 19c, and 113c is thinner than the thickness of the steel plate containing portion 2C on one surface 21c side in the thickness direction of the steel plate containing portion 2C.

[0098] The iron plate containing portion 2C and each of the flap portions 31c, 32c, 33c, and 34c are connected to the other surface 10c of the iron plate containing portion 2C in the thickness direction, with the horizontal planes being the same. An adhesive layer (not shown) is provided on the other surface 10c of the iron plate containing portion 2C in the thickness direction.

[0099] Within the flap portion 31c, there are further formed a plurality of flap groove portions 12c, 13c and 14c on one surface side, which have a thickness thinner than the thickness of the iron plate containing portion 2C and are formed with a concave structure that can be bent and deformed.

[0100] Furthermore, in the flap portion 32c, a plurality of flap grooves 16c, 17c, and 18c are formed on one surface side with a thickness thinner than the thickness of the steel plate containing portion 2C and formed with a bendable and deformable concave structure. Similarly, in the flap portion 33c, a plurality of flap grooves 110c, 111c, and 112c are formed, and similarly, in the flap portion 34c, a plurality of flap grooves 114c, 115c, and 116c are formed.

[0101] The thickness of the sheet from the flap surfaces 311c to 314c to the back surface 10c may be the same as or thinner than the thickness of the iron plate-containing portion 2C. The same applies to the thickness from the flap surfaces 321c to 324c to the back surface 10c, from the flap surfaces 331c to 334c to the back surface 10c, and from the flap surfaces 341c to 344c to the back surface 10c.

[0102] The portion directly below the other surface 10c side (referred to as the back side) of the iron plate containing portion 2C is a flat portion with no flexibility, and when the flexible sheet 1C is attached to a curved object, the flap portions 31c, 32c, 33c and 34c must complement the adhesive surface for attachment.

[0103] The planar shape of the iron plate containing portion 2C shown in Figure 18(a) is rectangular, and flap portions 31c, 32c, 33c, and 34c are connected along the perpendicular direction to the sides of the rectangle (corresponding to the up / down and left / right directions on the paper surface).

[0104] By providing the flaps 31c, 32c, 33c, and 34c along the top, bottom, left, and right directions of this rectangular shape, the flexible sheet 1C can be made difficult to peel off. tc and horizontal t yc The width of the mounting area Sc becomes large, and the mounting location on the oil tank of a motorcycle or the like becomes limited.

[0105] On the other hand, the flexible sheet 1A of the first embodiment has a sheet longitudinal length t ta and seat side ya Regarding the width (installation area Sa), the planar shape of the iron plate containing portion 2A shown in FIG. 2(a) is a rectangle, and the flap portions 31a, 32a, 33a, and 34a are connected along the diagonal direction relative to the sides of the rectangle, so that the sheet longitudinal t ta For example, the shape of the oil tank of a saddle-type vehicle such as a motorcycle or three-wheeled vehicle is a complex, uneven, curved surface, so it is necessary to make it long and narrow (the width of the seat is t ya Compared to the width of the sheet, the longitudinal taA shape that reduces the width dimension is easier to attach to shapes such as oil tanks.

[0106] The flexible sheet of this embodiment has a concave structure with excellent flexibility, and the thickness of the sheet can be increased, so a thick iron plate can be used as the magnetic body, thereby increasing the magnetic force of the flexible sheet.

[0107] The flexible sheet of this embodiment can be flexibly attached to a flat or uneven surface of an object, particularly to an oil tank of a saddle-ride type vehicle or a portion of the vehicle corresponding to the position of the oil tank, and a magnet can be strongly attracted to the attached portion. Also, the tank bag of this embodiment can be used when attached to an oil tank of a saddle-ride type vehicle or a portion of the vehicle corresponding to the position of the oil tank.
