[0002] Japanese Utility Model Application Laid-Open No. 63-140212 describes a watch band that is made of a material harder than resin and has a lug component embedded in one end of a resin (polyurethane) watch band, thereby making the portion (lug portion) attached to the main body case thinner and stronger.

[0003] When inserting a member made of a material harder than the resin material (referred to as an "embedded member") into the end of a belt formed of various resins, it is necessary to firmly bond the embedded member to the resin material constituting the belt's main body.

[0004] However, there is a problem that the adhesion between the insert component formed of a material harder than the resin material and the resin material is poor, and it is difficult to achieve a strong connection.

[0005] The present invention aims to improve and solve the problem in this case and can be firmly fixed to the main body housing. Summary of the invention

[0006] In order to solve the above problems, the present invention provides a belt installed on a main body shell, wherein the belt is characterized in that it includes:

[0007] a belt main body formed of a resin material; and

[0008] an embedded component arranged on the mounting side of the belt body relative to the main body shell,

[0009] The entirety of the embedding component is covered with the resin material of the belt body.

[0010] According to the present invention, the resin belt can be firmly fixed to the main body casing. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] [First embodiment]

[0032] Reference Figures 1 to 8 A first embodiment of the belt and the timepiece according to the present invention will be described.

[0033] In addition, in the first embodiment described below, the band is provided on a watch worn on the wrist (hereinafter referred to as "watch 100") as an example. In addition, although there are various technically preferred limitations for implementing the present invention in the first embodiment below, it is not intended to limit the scope of the present invention to the first embodiment and the illustrated examples below.

[0034] [structure]

[0035] Figure 1 It is a schematic plan view of a timepiece equipped with the band according to the first embodiment.

[0036] like Figure 1 As shown, the timepiece 100 according to the first embodiment includes a timepiece body 1 and a band 2 connected to a main body case 10 of the timepiece body 1 .

[0037] First, the main body case 10 constituting the watch body 100 is formed in a hollow short columnar shape.

[0038] The material forming the main body case 10 is not particularly limited, and it may be formed of, for example, hard synthetic resins such as super engineering plastics such as polyarylate (PAR) or engineering plastics such as polyacetal (POM), or hard materials such as various metals such as titanium or stainless steel SUS.

[0039] Although not shown in the figure, a watch module is housed in the hollow portion of the main body case 10. The watch module includes, for example, a watch movement including an analog display mechanism or a digital display mechanism such as a liquid crystal display unit that moves the hands, a circuit unit that controls these drives, and various components required for the watch function. In addition, a display unit 11 that displays the time or various information is provided on the surface of the main body case 10. In addition, operating components such as a crown or a button that are not shown in the figure are provided on the side of the main body case 10.

[0040] also, Figure 1 The watch body 1 is schematically shown, and does not accurately show a specific shape or structure.

[0041] like Figure 1 As shown, band attachment portions 12 for connecting the band 2 to the main body case 10 are provided on the outer side of the main body case 10 at positions corresponding to the 6 o'clock side and the 12 o'clock side in the analog timepiece.

[0042] The belt mounting portion 12 in the illustrated example has a shape in which lugs 121 protrude from both sides in the width direction of the main body housing 10, and the mounting portion 22 of the belt 2 is fitted between the lugs 121. In addition, the shape of the belt mounting portion 12 is not limited to the illustrated example. The belt 2 is provided with a mounting portion 22 that matches the shape of the belt mounting portion 12.

[0043] like Figure 1 As shown, the belt 2 is installed on the main body case 10, and includes a mother belt (short belt) 2a installed on the belt mounting portion 12 on the 12 o'clock side of the analog clock, and a sword tip belt (long belt) 2b installed on the belt mounting portion 12 on the 6 o'clock side.

[0044] Since the mother tape 2a and the sword tip tape 2b have the same structure with respect to the mounting portion 22 of the main body case 10, the mother tape 2a and the sword tip tape 2b are simply referred to as "tapes 2" without being distinguished from each other.

[0045] Figure 2 is a plan view of the main part of the periphery of the attachment portion of the belt to the main body case in the first embodiment as viewed from the surface side of the belt, Figure 3 This is a top view of the main part of the periphery of the mounting portion of the belt relative to the main body housing in the first embodiment as viewed from the back side of the belt. Figure 4 is a side view of a main part of the periphery of the mounting portion of the belt relative to the main body housing in the first embodiment, Figure 5 This is a perspective view of the main part of the first embodiment, viewed from the surface side of the belt, around the attachment portion of the belt relative to the main body housing. Figure 2 First, in the belt 2, a belt main body 20 described later is indicated by a two-dot chain line, and the insert component 3 is indicated by a solid line.

[0046] like Figures 2 to 5 As shown, the belt 2 includes a belt body 20 and an embedded component 3 .

[0047] The belt body 20 is formed of a resin material. As the resin material forming the belt body 20, for example, a relatively soft synthetic resin such as fluororubber (a resin having rubber elasticity composed of fluororesin), polyurethane resin, silicone resin, etc. is used. In addition, the material forming the belt body 20 is not limited to the materials exemplified here.

[0048] The belt body 20 includes a belt body 20 extending in the length direction L of the belt 2 (see Figure 1 ) A main body portion 21 having a longer belt-shaped portion, and an installation portion 22 installed on the belt installation portion 12 of the main body shell 10.

[0049] The embedded component 3 is a component that is arranged in the belt body 20 on the mounting side relative to the main body shell 10 (the side mounted on the belt mounting portion 12). The embedded component 3 is formed by cutting various metal materials such as titanium or stainless steel (SUS), and is a component with strength and rigidity. In addition, the material forming the embedded component 3 is not limited to metal materials. Various hard materials similar to metals that have sufficient strength and rigidity can be used. In addition, the method of forming the embedded component 3 is not limited to cutting, and various methods can be used. For example, it can be formed using a 3D printer.

[0050] When the belt 2 is molded, the insert member is arranged on the mounting portion 22 side of the resin material forming the belt body 20 and insert-molded.

[0051] like Figures 2 to 5 As shown in , the embedding component 3 includes a main body 31 and a connecting portion 32 .

[0052] The main body 31 is in the width direction W of the belt 2 (refer to Figure 1 ) is a longer part on the belt 2. When looking down at the front side of the belt 2, the main body 31 is formed with a plurality of filling holes 33 (see Figure 6 The filling hole 33 (first hole portion) is a hole portion into which the resin material forming the belt body 20 is filled during insert molding.

[0053] In the first embodiment, the filling holes 33 are formed in the width direction W of the belt 2 (see Figure 1 ) is a long hole whose length is longer than the length L of the belt 2. Figure 2 and Figure 3 As shown in FIGS. 1 and 1B , the filling hole 33 penetrates through the front and back surfaces of the main body 31 of the embedding component 3 .

[0054] The two filling holes 33 shown in the first embodiment are arranged along the width direction W of the belt 2. In addition, the number and arrangement of the filling holes 33 are not limited to the illustrated example. For example, three or more filling holes 33 may be arranged along the width direction W of the belt 2. In this case, the length of each filling hole 33 may be shorter than that of two filling holes. Furthermore, the width of the belt 2 in the length direction L in the main body 31 may be increased, and a plurality of filling holes 33 may be arranged in parallel along the length direction L of the belt 2. In addition, a plurality of filling holes 33 may be arranged in the width direction W of the belt 2 and in the length direction L of the belt 2, or, for example, two may be arranged in the width direction W of the belt 2, and two may be arranged in the length direction L of the belt 2, for a total of four, etc. When a plurality of filling holes 33 are provided in the width direction W of the belt 2 and in the length direction L of the belt 2 in this way, the filling holes 33 may also be arranged in a staggered manner, for example, by staggering the positions in the length direction L of the belt 2.

[0055] Figure 6 yes Figure 2 An enlarged view of section VI in FIG.

[0056] like Figure 1 , Figure 2 and Figure 6 As shown, the connection portion 32 is formed to protrude from the main body 31 toward the installation side relative to the main body housing 10 .

[0057] like Figures 2 to 5 As shown in FIG. 1 and FIG. 2 , two connection portions 32 are provided in the first embodiment.

[0058] Figure 7 yes Figure 4 The enlarged view of part VII, Figure 8 yes Figure 5 An enlarged view of section VIII.

[0059] like Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, each connecting portion 32 is formed with a plurality of connecting portions extending in the width direction W of the belt 2 (see Figure 1 ) through the shaft hole 322 (refer to Figure 5 and Figure 8 ).

[0060] In particular, Figure 7 and Figure 8 As shown, the insert component 3 is insert-molded so that the entire body 31 and the connecting portion 32 are covered with the resin material of the belt body 20 .

[0061] In addition, if Figure 8As shown, a through hole 222 is formed in the mounting portion 22 of the belt body 20 at a position corresponding to the shaft hole 322 of the connecting portion 32. Even during insert molding, the through hole 222 and the shaft hole 322 are connected without being blocked by the resin material, and in the mounting portion 22 of the belt 2 as an insert molded product, the through hole 222 and the shaft hole 322 form a longitudinal direction W (refer to FIG. 1 ) of the belt 2. Figure 1 ) through-portion 25.

[0062] When the attachment portion 22 is attached to the belt attachment portion 12 of the main body housing 10 , a spring bar (not shown) or the like is inserted through the through-portion 25 , whereby the attachment portion 22 of the belt 2 is locked to the belt attachment portion 12 .

[0063] [effect]

[0064] Next, the operation of the band 2 and the timepiece 100 including the band 2 according to the first embodiment will be described.

[0065] When forming the belt 2, the insert component 3 is arranged on the side corresponding to the mounting portion 22 of the belt 2 as an insert molded product in the insert molding die, and the resin material (for example, fluororubber, etc.) constituting the belt body 20 is injected around it and the insert molding is performed to form the belt 2 as a whole (composite molding). At this time, the filling hole 33 of the insert component 3 is in a state filled with the resin material.

[0066] The belt 2 formed in this way has the through portion 25 in the mounting portion 22 .

[0067] When the band 2 is mounted on the watch body 1, the mounting portion 22 of the band 2 is fitted into the band mounting portion 12 of the main body case 10 of the watch body 1, and a spring bar or the like is inserted through the through portion 25. Thus, the band 2 is locked to the main body case 10.

[0068] Not only when the band 2 is attached or detached, but also when the timepiece 100 is worn on the wrist for use, the side of the band 2 attached to the main body case 10 is repeatedly subjected to a pulling force or a torsional force, which causes a burden.

[0069] In this regard, in the belt body 20, an insert component 3 formed of a metal material or the like is arranged inside the mounting side of the belt 2 including the mounting portion 22 mounted on the belt mounting portion 12 of the main body case 10. Thus, the mounting portion 22 is reinforced so as to be less likely to be deformed by an external force and can withstand repeated loads.

[0070] Furthermore, the entire insert component 3 is covered with the resin material, and a filling hole 33 is provided in the main body 31 of the insert component 3, which passes through from the front side to the back side, and the resin material for molding the belt main body 20 is filled in the filling hole 33. Therefore, the resin material is wound around the insert component 3 and firmly integrated, so that the belt 2 is difficult to be damaged.

[0071] [Effect]

[0072] As described above, the belt 2 in the first embodiment is a belt 2 installed on the main body shell 10, including a belt body 20 formed of a resin material, and an embedded component 3 arranged in the belt body 20 on the installation side relative to the main body shell 10, and the embedded component 3 is covered as a whole by the resin material of the belt body 20.

[0073] Thus, the resin material used to form the belt body 20 and the metal or other embedded component 3 as a reinforcing member can be firmly integrated. Therefore, even if the user pulls the belt 2 strongly, the belt 2 will not break, and it is not easy to be deformed by external force, so that the belt 2 can have high rigidity and durability.

[0074] The insert member 3 of the first embodiment has a plurality of filling holes 33 as hole portions for filling the resin material (for example, fluororubber or the like) of the belt body 20 during insert molding.

[0075] Thus, the resin material is wound around the insert component 3, and in the belt 2 as an insert molded product, the belt body 20 formed of the resin material and the insert component 3 formed of the metal material are firmly integrated. Therefore, the belt 2 is not easily deformed by tension or external force, and the belt 2 can have high rigidity and durability.

[0076] In addition, the length of the filling hole 33 as the hole portion in the first embodiment is longer in the width direction W of the belt 2 than in the length direction L of the belt 2 (see Figure 1 ) of the slotted hole.

[0077] Therefore, the main body 31 as the portion where the filling hole 33 is formed can be made to be as Figure 6 The length W of the band 2 in the width direction is longer than the length L of the band 2 in the length direction. Thus, the strength of the mounting side of the band 2 can be improved, and the portion where the embedded component 3 is arranged inside can be limited to a narrow range relative to the mounting side of the main body case 10. Therefore, without impairing the wearing feeling of the resin band 2 formed of a relatively soft resin material such as fluororubber, a band 2 with good touch and familiarity with the wrist can be realized.

[0078] Furthermore, when such a band 2 is attached to the main body case 10 of the timepiece body 1 to form a timepiece 100 (wristwatch), it is possible to realize a timepiece 100 having an excellent wearing feeling and excellent durability of the band 2 .

[0079] As mentioned above, although the 1st embodiment of this invention was demonstrated, this invention is not limited to 1st embodiment, Of course, various changes can be made suitably within the range which does not deviate from the summary.

[0080] Furthermore, although the first embodiment of the present invention has been described above, the present invention is not limited to the first embodiment, and it is apparent that various modifications can be made as appropriate within the scope not departing from the gist of the present invention.

[0081] For example, the shape of the embedded component is not limited to Figures 2 to 5 The shapes shown can be changed appropriately.

[0082] [Second embodiment]

[0083] Figures 9 to 13 An example in which the insert component in the second embodiment is assembled to the belt 2 is shown.

[0084] Fig. 9 is a plan view of the main part of the periphery of the attachment portion of the belt to the main body case in the second embodiment as viewed from the surface side of the belt, Fig.10 This is a top view of the main part of the second embodiment, viewed from the back side of the belt, around the mounting portion of the belt relative to the main body housing. Fig.11 1 is a side view of the main part of the second embodiment of the belt relative to the main body shell of the surrounding parts. Figures 9 to 13 Similarly, in the belt 2, the belt body 20 is indicated by a two-dot chain line, and the embedded component 4 is indicated by a solid line. Figures 9 to 13 The belt 2 shown is the same as that of the embodiment except for the embedding member 4, and therefore the same reference numerals are given to the same components and their description is omitted.

[0085] like Fig. 9 and Fig.10 As shown, the embedded component 4 in the second embodiment is arranged in the width direction W of the belt 2 (see Figure 1 ) is formed longer and includes a main body 41 and a connecting portion 42.

[0086] The main body 41 has a substantially inverted trapezoidal shape in a plan view, particularly with a longer side on the side where the main body case 10 is mounted. The connecting portion 42 is formed to protrude toward the side of the main body 41 where the main body case 10 is mounted (the long side of the inverted trapezoid).

[0087] The embedded component 4 is formed using various metal materials such as titanium and stainless steel (SUS) using a 3D printer (metal 3D printer) or the like. The material forming the embedded component 4 is not limited to metal, and various hard materials having sufficient strength and rigidity similar to metal can be used. In addition, the method of forming the embedded component 4 is not limited to the 3D printer, and other methods can also be used.

[0088] In addition, the shape and the like of the connection portion 42 are the same as those of the connection portion 32 in the first embodiment.

[0089] Fig.12 yes Fig. 9 An enlarged view of part XII, Fig.13 yes Fig.11 Magnified view of section XIII.

[0090] like Fig.11 and Fig.13 As shown, an axial hole 422 is formed in the connecting portion 42 at the same position as the axial hole 322 of the connecting portion 32 .

[0091] In addition, if Fig.12 As shown, a plurality of filling holes 43 (first hole portions) are formed in the main body 41 of the insert member 4.

[0092] exist Fig. 9 , Fig.10 and Fig.12 In the second embodiment shown, the filling hole 43 is formed in the longitudinal direction L of the belt 2 (see Figure 1 ) is a long hole whose length is longer than the length in the width direction W of the belt 2. In the example shown in the figure, a plurality of slit-shaped hole portions are arranged in an array. Fig. 9 and Fig.10 As shown, the filling hole 43 penetrates the front and rear sides of the main body 41 of the insert component 4 .

[0093] In addition, the shape and arrangement of the filling hole 43 are not limited to the example shown in the figure. For example, the filling hole 43 may be a hole portion having a wide width in the width direction W of the belt 2. In this case, two filling holes 43 may be arranged in the width direction W of the belt 2. In addition, in the example shown in the figure, the filling hole 43 is provided slightly inclined relative to the longitudinal direction of the belt 2, but the filling hole 43 may be provided parallel to the longitudinal direction L of the belt 2, for example.

[0094] In addition, if Fig.11 and Fig.13 As shown, a filling hole 44 is also formed on the side surface of the insert member 4. The filling hole 44 (second hole portion) on the side surface penetrates in the width direction of the main body 41 similarly to the shaft hole 422.

[0095] like Figures 9 to 13 As shown, for the belt 2, when an embedded component 4 is provided in the belt 2, during the embedding molding, when the resin material of the belt body 20 covers the entire embedded component 4 including the main body 41 and the connecting portion 42, the resin material enters the filling holes 43, 44 from the longitudinal direction (front-to-back direction of the belt 2) and the transverse direction (width direction W of the belt 2), and is fully entangled with the embedded component 4.

[0096] Thus, the resin material constituting the belt body 20 and the embedding component 4 are firmly integrated, so that the belt 2 will not break even if it is pulled strongly, is not easily deformed by external forces, and can have high rigidity and durability.

[0097] [Third Embodiment]

[0098] in addition, Figures 14 to 20 An example in which the insert component in the third embodiment is assembled to the belt 2 is shown.

[0099] Fig.14 This is a plan view of the main part of the third embodiment, as viewed from the surface side of the belt, around the attachment portion of the belt to the main body case. Fig.15 This is a top view of the main part of the periphery of the attachment portion of the belt relative to the main body housing in the third embodiment as viewed from the back side of the belt. Fig.16 1 is a side view of the main part of the periphery of the mounting portion of the belt relative to the main body shell in the third embodiment, Fig.17 This is a perspective view of the main part of the third embodiment, viewed from the surface side of the belt, around the mounting portion of the belt relative to the main body housing. Figures 14 to 20 Similarly, in the belt 2, the belt body 20 is indicated by a two-dot chain line, and the embedded component 5 is indicated by a solid line. Figures 14 to 20 The belt 2 shown is the same as that of the first embodiment except for the insert member 5, and therefore the same components are denoted by the same reference numerals and their description is omitted.

[0100] like Fig.14 and Fig.15 As shown, the embedded component 5 in the third embodiment is arranged in the width direction W of the belt 2 (see Figure 1 ) is formed longer and includes a main body 51 and a connecting portion 52.

[0101] In addition, the shape and the like of the connection portion 52 are the same as those of the connection portion 32 in the first embodiment.

[0102] Fig.18 yes Fig.14 An enlarged view of part XVIII of Fig.19 yes Fig.16 An enlarged view of the IXX section. Fig. 20 yes Fig.17 Enlarged view of the XX part.

[0103] like Fig.16 and Fig.19 As shown, an axial hole 522 is formed in the connecting portion 52 at the same position as the axial holes 322 and 422 in the connecting portion 32 and the connecting portion 42 .

[0104] The embedded component 5 is made of various metal materials such as titanium or stainless steel (SUS), and is formed using a 3D printer (metal 3D printer) or the like as the embedded component 4. In addition, the material forming the embedded component 5 is not limited to metal, and various hard materials having sufficient strength and rigidity similar to metal can also be used. In addition, the method of forming the embedded component 5 is not limited to the 3D printer, and other methods can also be used.

[0105] In addition, if Fig.18 , Fig.19 , Fig. 20 As shown, filling holes 53, 54, and 55 are formed in the main body 51 of the embedded component 5. Specifically, in the main body 51 of the embedded component 5, when the belt 2 is viewed from above, a plurality of filling holes 53 (first hole portion) are formed. Next, when the belt 2 is viewed from the side of one side, a plurality of filling holes 54 (second hole portion) are formed in the main body 51 of the embedded component 5. Next, when the belt 2 is viewed from the side of another direction orthogonal to the one side, a plurality of filling holes 55 (third hole portion) are formed in the main body 51 of the embedded component 5.

[0106] That is, in Figures 14 to 20 In the third embodiment shown, the main body 51 of the insert component 5 has a width direction W of the belt 2 and a length direction L of the belt 2 (see Figure 1 ) is formed in a lattice-like hollow structure portion 530, and the hollow structure portion 530 includes filling holes 53, 54, and 55 as the hole portion for filling the resin material constituting the belt body 20 during insert molding.

[0107] The hollow structure portion 530 is a hollow structure formed by continuously repeating a plurality of three-dimensional lattice units, and has a so-called lattice structure. In addition, the shape of the lattice of the lattice structure is not limited to the example shown in the figure.

[0108] like Fig.18 , Fig.19 , Fig. 20 As shown in the figure, for the main body 51, the filling hole 53 passes through the longitudinal direction (up and down, front and back directions) of the belt 2, the filling hole 54 passes through the transverse direction (the width direction W of the belt 2), and the filling hole 55 passes through the length direction (the length direction L of the belt 2).

[0109] Thus, when the embedded component 5 is arranged in the belt 2, during the embedding molding, when the embedded component 5 including the main body 51 and the connecting part 52 is covered as a whole with the resin material of the belt main body 20, the resin material enters the filling holes 53, 54, 55 from the longitudinal direction (front-to-back direction of the belt 2), the transverse direction (width direction W of the belt 2) and the length direction (length direction L of the belt 2), and is fully entangled with the embedded component 5.

[0110] Thus, the resin material constituting the belt body 20 and the embedding component 5 are firmly integrated with each other, and the belt 2 will not break even if pulled strongly, and is not easily deformed by external forces, and the belt 2 can have high rigidity and durability.

[0111] Thus, for the belt 2, when a lattice structure is adopted in the embedded component 5 (especially the hollow structure 530 of the main body 51), since it is a hollow structure, the embedded component 5 can be made lighter than a solid structure, and the amount of required material can be reduced. Furthermore, since the hollow structure 530 is filled with a plurality of lattice structures that are repeated continuously, it is possible to achieve high rigidity while being lighter.

[0112] In addition, the filling holes 33 (first hole), 43 (first hole), 44 (second hole), 53 (first hole), 54 (second hole), and 55 (third hole) provided in the main bodies 31, 41, and 51 of the insert components 3, 4, and 5 shown in the first to third embodiments are all exemplified as through holes. However, a part or all of the filling holes 33, 43, 44, 53, 54, and 55 may include a non-through recessed portion or the like. In the case where a part or all of the filling holes 33, 43, 44, 53, 54, and 55 of the insert components 3, 4, and 5 are recessed portions, the resin material constituting the belt main body 20 and the insert components 3, 4, and 5 are entangled during insert molding, and the belt main body 20 and the insert components 3, 4, and 5 can be integrated as desired.

[0113] In the first to third embodiments, metals and various hard materials having sufficient strength and rigidity similar to metals are cited as materials for forming the embedded components 3, 4, and 5. However, the present invention is not limited to this structure. The materials constituting the embedded components 3, 4, and 5 can be any materials as long as they are harder than the resin material constituting the belt body 20.

[0114] In the present embodiment, an example in which the band 2 is connected to the main body case 10 of the timepiece 100 is described, but the band 2 is not limited to a band 2 for a timepiece attached to the main body case 10 of the timepiece 100 .

[0115] For example, the band 2 of the present invention can be used as a band connected to a main body case of various devices (eg, a smart watch, a pedometer, a heart rate meter, etc.) fixed to the body via the band 2 .

[0116] Although some embodiments of the present invention are described above, the scope of the present invention is not limited to the above embodiments. The specific configurations, structures, and positional relationships shown in the first, second, and third embodiments can be appropriately changed without departing from the gist of the present invention. The present invention includes the scope of the invention described in the claims and its equivalent scope.
