FIG. As shown in FIG. 3, the axial length of the pipe 104 is slightly longer than the axial length of the through hole 1012. Therefore, as shown in FIG. 3, when assembled as a unit piece 10, the end of the pipe 104 slightly protrudes outward from each of the two openings of the through hole 1012, and the inner piece 101 and the outer piece 102 </ b> L. And an appropriate gap is secured between each of the outer pieces 102R. As a result, the rotation between the inner piece 101 and the outer piece 102L and the outer piece 102R is configured to be smooth.

  Subsequently, the long component 1031L is inserted into the through hole 1021 of the outer piece 102L from the outer surface side, and the short component 1031R is inserted into the through hole 1021 of the outer piece 102R from the outer surface side in the direction shown in FIG. When the long component 1031L and the short component 1031R are pushed inward in the width direction, a ring-shaped unevenness provided on the outer surface of the fitting portion of the long component 1031L and a ring provided on the inner surface of the short component 1031R When the concave and convex portions are engaged with each other, the fitting is performed.

  When the long part 1031L and the short part 1031R are fitted as described above, the head part of the long part 1031L is at the stepped portion of the inner wall surface of the through hole 1021 of the outer piece 102L, and the head part of the short part 1031R is the outer piece. The hooks are respectively hooked to the step portions of the inner wall surface of the through-hole 1021 of 102R, and the movement of the outer piece 102L and the outer piece 102R to the outside in the width direction is restricted with respect to the inner piece 101. As a result, the outer piece 102L and the outer piece 102R are connected to the inner piece 101, and the assembly of the unit piece 10 is completed.

  In the band 1, a plurality of unit pieces 10 are sequentially connected in a direction perpendicular to a plane including the width direction and the vertical direction (hereinafter referred to as “connection direction”) so as to be rotatable around an axis in the width direction. Realized. Hereinafter, another unit piece 10 adjacent to one unit piece 10 is referred to as a unit piece 10 ′, and each component included in the unit piece 10 ′ is denoted by “′”.

  FIG. 4 is a diagram for explaining a mechanism for connecting the unit piece 10 and the unit piece 10 ′. In FIG. 4, not all the components included in the unit piece 10 ′ are shown, but only the inner piece 101 ′ involved in the connection with the unit piece 10 is shown.

  When the unit piece 10 and the inner piece 101 ′ of the unit piece 10 ′ are connected, a connecting piece assembly 11 shown in FIG. 4B is obtained. In addition to the unit piece 10 and the inner piece 101 ′ of the unit piece 10 ′, the connecting piece assembly 11 includes a connecting pin 105, a pipe 106, a cap 107L, a cap 107R, a locking pin 108L, an engaging member as components necessary for connecting them. A stop pin 108R is provided.

  The connecting pin 105 is a simple cylindrical bar. The pipe 106 has a simple hollow cylindrical shape, and its outer diameter is substantially equal to the diameter of the through hole 1011 ′ of the inner piece 101 ′, and its inner diameter is slightly larger than the diameter of the connecting pin 105.

  The cap 107L and the cap 107R have the same shape and structure. Therefore, hereinafter, when it is not necessary to distinguish between the cap 107L and the cap 107R, they are simply referred to as the cap 107.

  The cap 107 is a hollow box-like body that is generally open on one side surface, and has a size and shape that can accommodate the outer piece 102 in the hollow portion. In addition, a through-hole 1071 penetrating in the vertical direction is provided at substantially the center of the bottom wall portion of the cap 107 in FIG.

  The locking pin 108L and the locking pin 108R have the same shape and structure. Therefore, hereinafter, when it is not necessary to distinguish between the locking pin 108L and the locking pin 108R, they are simply referred to as the locking pin 108.

  The locking pin 108 is shortened in length in the longitudinal direction by pressing down a head portion provided at one end portion (lower end portion in FIG. 4) with a force of a predetermined magnitude or more from the outside. It has a structure. Specifically, the locking pin 108 has a structure shown in FIG.

  That is, the locking pin 108 has a substantially cylindrical casing 1081, a head portion 1082 accommodated in the casing 1081, and the casing 1081 so as to press the head portion 1082 outward (downward in FIG. 5). And a coil spring 1083 accommodated therein.

  At the edge of the other opening of the casing 1081 (the opening on the lower side in FIG. 5), a hook that protrudes in the direction toward the cylindrical axis, that is, inward, and forms a ring shape as a whole is provided. A step provided on the head portion 1082 hooks on the hook. As a result, the head portion 1082 remains in the casing 1081 while being urged downward from the coil spring 1083 in FIG.

  The procedure for assembling the connecting piece assembly 11 by connecting the inner piece 101 ′ of the unit piece 10 ′ to the unit piece 10 is as follows, for example. First, the pipe 106 is inserted into the through hole 1011 ′ of the inner piece 101 ′. Subsequently, the inner piece 101 ′ is disposed between the outer piece 102L and the outer piece 102R of the unit piece 10 so that the axis of the through hole 1011 ′ and the axis of the through hole 1022 of the outer piece 102L and the outer piece 102R coincide with each other. Adjust the position to. As a result, the through hole 1022 of the outer piece 102L, the through hole 1011 'of the inner piece 101', and the through hole 1022 of the outer piece 102R are connected, and one piece extends from the outer side of the outer piece 102L to the outer side of the outer piece 102R. A through hole is formed.

  FIG. 6 shows the inner piece 101, the outer piece 102L, the outer piece 102R, the pipe 104, the inner piece 101 ′, and the pipe 106 in such a state, the through hole 1011, the through hole 1012, the through hole 1021, and the through hole. It is sectional drawing at the time of cut | disconnecting by the plane containing the axis | shaft of 1022, through-hole 1011 ', and through-hole 1012'.

  As shown in FIG. 6, the axial length of the pipe 106 is slightly longer than the axial length of the through hole 1011 ′. Therefore, when assembled as the connecting piece assembly 11, the end of the pipe 106 slightly protrudes outward from each of the two openings of the through-hole 1011 ', and the inner piece 101', the outer piece 102L, and the outer piece 102R A moderate gap is secured between each. As a result, the inner piece 101 ′ and the outer piece 102 </ b> L and the outer piece 102 </ b> R are configured to rotate smoothly.

  Subsequently, as shown in FIG. 7, the connecting pin 105 is inserted into the through hole 1022 from the outer surface side of the outer piece 102 </ b> L. The connecting pin 105 may be inserted into the through hole 1022 from the outer surface side of the outer piece 102R.

  Subsequently, each of the locking pin 108L and the locking pin 108R is inserted into the through hole 1023 of each of the outer piece 102L and the outer piece 102R from the side of the head portion 1082 from the upper surface side in FIG. FIG. 8 is a view showing a part of the connecting piece assembly 11 in a state in which the locking pin 108 is inserted into the through hole 1023. In FIG. 8, the display of the inner frame 101 and the inner frame 101 'is omitted. In other words, the inner piece 101 is actually connected so as to accommodate the pipe 104 in the through hole 1012 and the inner piece 101 'is connected so as to accommodate the pipe 106 in the through hole 1011'.

  Subsequently, each of the cap 107L and the cap 107R is put on the outer piece 102L and the outer piece 102R. FIG. 9 is a diagram showing a state where the outer piece 102 is covered with the cap 107. However, in FIG. 9, rotation is performed 180 degrees about the width direction so that the bottom surface side in FIG. 4 is the top surface side.

  More specifically, after positioning the cap 107 so that the opening of the cap 107 coincides with the outer surface of the outer piece 102, the cap 107 is positioned inward in the width direction with respect to the outer piece 102 (in the direction of the arrow in FIG. 9). The outer piece 102 is accommodated in the hollow portion of the cap 107. In order to avoid the end of the cap 107 from colliding with the head portion 1082 of the locking pin 108 during the sliding of the cap 107, the head portion 1082 is applied with a force greater than or equal to a predetermined level using, for example, a pen tip. The head part 1082 is housed inside the cap 107 by pressing the button.

  When the cap 107 is put on the outer piece 102, the head portion 1082 of the locking pin 108 is fitted into the through hole 1071 provided in the cap 107, and the cap 107 is locked to the outer piece 102.

  By covering the outer piece 102 with the cap 107, the outer piece 102 and the end portions of the connecting pin 103 and the connecting pin 105 exposed on the outer surface of the outer piece 102 are covered with the cap 107 and cannot be visually recognized from the outside. As a result, the connecting piece assembly 11 appears as a connecting body of the inner piece 101, the inner piece 101 ', the cap 107L, and the cap 107R, and has a simple high-quality appearance.

  Further, the connecting pin 105 can freely move in the width direction. However, since the movement toward the outside in the width direction is restricted by the cap 107L and the cap 107R, the connecting pin 105 is not dropped off, and the inner side of the unit piece 10 The connection with the piece 101 'is ensured.

  The above is the procedure for assembling the connecting piece assembly 11. Actually, the inner piece 101 ′ of the connecting piece assembly 11 is connected to the outer piece 102L ′ and the outer piece 102R ′ of the unit piece 10 ′ adjacent to the unit piece 10. ing. Accordingly, the plurality of unit pieces 10 are sequentially arranged in the connecting direction, and after connecting them with the connecting pins 105 in accordance with the procedure for assembling the connecting piece assembly 11, the outer piece 102 is covered with the cap 107 to ensure the connection. Thus, the band 1 can be configured. FIG. 10 is a view showing the appearance of the band 1 configured as described above.

  The band 1 having the above-described structure can be easily disconnected at a connection position between an arbitrary inner piece 101 constituting the band 1 and outer pieces 102 located on both sides thereof. Specifically, the user slides the cap 107 outward in the width direction while pressing down the head portion 1082 of the locking pin 108 at the connection position to be released with a predetermined force or more using a pen tip or the like. At this time, since the locking by the head portion 1082 of the locking pin 108 fitted in the through hole 1071 is released, the user can easily remove the cap 107 from the outer piece 102.

  Subsequently, the user tilts the band 1 so that one end portion of the exposed connecting pin 105 faces downward. As a result, the connecting pin 105 is dropped from the through hole 1011 and the through holes 1022 connected to both sides thereof according to gravity. As a result, the connection between the inner piece 101 and the outer pieces 102 on both sides thereof is released.

  When the above-described frame connection is released at any two connection positions, one or more unit pieces 10 located between the connection positions can be removed from the band 1. After that, by connecting the band 1 divided into two according to the above-described procedure of assembling the connecting piece assembly 11, the length of the band 1 can be shortened to a desired length.

  Further, after the above-described piece connection is released at an arbitrary connection position and the band 1 is divided into two, one or more unit pieces 10 are connected between the two band pieces. It is possible to extend the length of the band 1 to a desired length by arranging the three band pieces so as to sandwich another band piece and connecting the three band pieces in accordance with the assembly procedure of the connecting piece assembly 11 described above. it can.

  As described above, according to the band 1 according to the present embodiment, the user can easily adjust the length by using personal items such as a pen tip without using a special tool.

[1.2. Second Embodiment]
Hereinafter, the band 2 according to the second embodiment of the present invention will be described. However, since the external appearance of the band 2 is substantially the same as the external appearance of the band 1 according to the first embodiment (see FIG. 10), the illustration thereof is omitted. The configuration and assembly procedure of the band 2 are common to the band 1 in many respects. Therefore, in the following explanation, the explanation will focus on the point where the band 2 is different from the band 1. In addition, the same reference numerals as those used in the band 1 are used for the components included in the band 2 that are common to or correspond to the components included in the band 1.

  FIG. 11 is a perspective view showing an exploded state of the unit piece 20 constituting the band 2. The configuration of the unit piece 20 is different from the unit piece 10 constituting the band 1 in that one of the two through holes extending in the width direction of the outer piece is different, and the other points are all unit. The same as the piece 10.

  FIG. 12 is a cross-sectional view when the outer piece 202 constituting the unit piece 20 is cut along a plane including two through holes extending in the width direction, that is, the axes of the through hole 1021 and the through hole 2022. As shown in FIG. 12, the through hole 2022 of the outer piece 202 is a hollow with a step formed by connecting two cylindrical shapes having different diameters, like the through hole 1021, and the diameter of the cylindrical shape on the outer surface side is It is slightly larger than the diameter of the cylindrical shape on the inner surface side.

  FIG. 13 is a diagram for explaining a coupling mechanism between a unit piece 20 and a unit piece 20 ′ having a similar structure adjacent to the unit piece 20. In FIG. 13, all the components included in the unit piece 20 ′ are not shown, and only the inner piece 101 ′ involved in the connection with the unit piece 20 is shown.

  When the unit piece 20 and the inner piece 101 ′ of the unit piece 20 ′ are connected, a connection piece assembly 21 shown in FIG. 13B is obtained. The connecting piece assembly 21 includes a connecting pin 205, a pipe 106, a cap 107L, a cap 107R, a locking pin 208L, an engaging pin as constituent elements required for connecting the unit piece 20 and the inner piece 101 ′ of the unit piece 20 ′. A stop pin 208R, a lock ring 209L, and a lock ring 209R are provided. The connecting pin 205 is composed of a long part 2051L and a short part 2051R, and they become a connecting pin 205 when they are fitted to each other.

  The locking pin 208L and the locking pin 208R have the same structure, and when it is not necessary to distinguish between the locking pin 208L and the locking pin 208R, they are simply referred to as the locking pin 208. The locking ring 209L and the locking ring 209R have the same structure, and when it is not necessary to distinguish the locking ring 209L and the locking ring 209R, they are simply referred to as the locking ring 209.

  Compared with the connection piece assembly 11, the connection piece assembly 21 is replaced with a connection pin 205, which is a simple cylindrical rod-like body, by using two pieces of connection pins 205 to form the unit piece 20 and the unit piece 20 ′. The difference is that the connection with the piece 101 'is performed. The structure of the connecting pin 205 is the same as the structure of the connecting pin 103.

  The connecting piece assembly 21 is also provided with a locking pin 208 and a locking pin 208 in place of the through hole 1023 of the outer piece 202 in place of the locking pin 108 having a depressible head portion 1082 as compared with the connecting piece assembly 11. The difference is that a locking ring 209 for fixing inside is used.

  The locking pin 208 is a cylindrical rod-like body, and is tapered so that, for example, the end of the outer piece 202 on the side inserted into the through hole 1023 becomes thinner toward the front. This taper process is performed when the locking pin 208 is inserted into the through-hole 1071 of the cap 107 covered with the outer piece 202 and the locking ring 209 accommodated in the through-hole 1023 of the outer piece 202 continuous thereto. It is for making it easy.

  The locking ring 209 is a cylindrical rod-like body provided with a cutout having a C-shaped cross section cut along a plane perpendicular to the longitudinal direction. The inner diameter is slightly smaller than the outer diameter of the locking pin 208, and the outer diameter is slightly smaller than the inner diameter of the through hole 1023 of the outer piece 202.

  The procedure for assembling the connecting piece assembly 21 by connecting the inner piece 101 ′ of the unit piece 20 ′ to the unit piece 20 is as follows, for example. First, the pipe 106 is inserted into the through hole 1011 ′ of the inner piece 101 ′. Subsequently, the inner piece 101 ′ is disposed between the outer piece 202L and the outer piece 202R of the unit piece 20 so that the axis of the through hole 1011 ′ and the axis of the through hole 2022 of the outer piece 202L and the outer piece 202R coincide. Adjust the position to. As a result, the through hole 2022 of the outer piece 202L, the through hole 1011 'of the inner piece 101', and the through hole 2022 of the outer piece 202R are connected, and one piece extends from the outer side of the outer piece 202L to the outer side of the outer piece 202R. A through hole is formed.

  Next, as shown in FIG. 14, the long component 2051L is inserted into the through hole 2022 of the outer piece 202L from the outer surface side, and the short component 2051R is inserted into the through hole 2022 of the outer piece 202R from the outer surface side. Then, when the long component 2051L and the short component 2051R are pushed inward in the width direction, the long component 2051L and the short component 2051R are fitted.

  When the long part 2051L and the short part 2051R are fitted as described above, the head part of the long part 2051L is at the stepped portion of the inner wall surface of the through hole 2022 of the outer piece 202L, and the head part of the short part 2051R is the outer piece. The hooks are respectively hooked to the step portions of the inner wall surface of the through-hole 2022 of 202R, and the movement of the outer piece 202L and the outer piece 202R to the outside in the width direction is restricted with respect to the inner piece 101 ′. As a result, the inner piece 101 ′ of the unit piece 20 ′ is connected to the unit piece 20.

  Subsequently, the cap 107 is attached to the outer piece 202. FIG. 15 is a diagram showing a procedure at that time. In FIG. 15, rotation is performed 180 degrees about the width direction so that the bottom surface side in FIG. 13 is the top surface side.

  First, before the outer piece 202 is covered with the cap 107, the locking ring 209 is inserted into the through hole 1023 of the outer piece 202. Thereafter, the cap 107 is slid with respect to the outer piece 202 in the direction of the arrow in FIG. 15, and the cap 107 is moved to a position where the axis of the through hole 1023 of the outer piece 202 and the axis of the through hole 1071 of the cap 107 substantially coincide. Put on. At this time, the sizes of the locking ring 209 accommodated in the through hole 1023 and the inner diameter of the through hole 1071 of the cap 107 are adjusted to be substantially the same.

  Subsequently, the locking pin 208 is inserted into the locking ring 209 accommodated in the through hole 1023 via the through hole 1071. At that time, the outer wall of the locking pin 208 spreads the locking ring 209 outward, and the locking ring 209 tightens the locking pin 208 from the outside to the inside by its elasticity, so that the locking pin 208 is moved to the locking ring 209. Hold. By the way, since the outer diameter of the locking ring 209 is larger than the inner diameter of the through hole 1071 of the cap 107, it cannot pass through the through hole 1071. Accordingly, the locking pin 208 is held in the through hole 1023 while being held by the locking ring 209.

  As described above, the length of the locking pin 208 in the state of being held in the through hole 1023 is adjusted so that the end of the through hole 1071 side protrudes from the outer piece 202 to the through hole 1071. ing. Therefore, the end of the protruding locking pin 208 fits into the through hole 1071, and the cap 107 is locked to the outer piece 202.

  The assembly of the connecting piece assembly 21 is completed by the above procedure. The band 2 is configured by sequentially connecting the plurality of unit pieces 20 in the connecting direction according to the assembly procedure of the connecting piece assembly 21 described above.

  In the band 1, the cap 107 can be easily attached and detached by pressing the head portion of the locking pin 108, and the unit piece 10 can be easily attached and detached without using a special tool. On the other hand, once the cap 107 is fixed by the locking pin 208 in the band 2, it is not easy to remove the locking pin 208. Therefore, it is difficult to release the connection between the unit pieces 20 in the band 2. Therefore, the structure of the band 2 is suitable for use in applications that do not require length adjustment by the user.

  In the band 2, instead of the connecting pin 105 of the band 1, a connecting pin 205 configured by fitting a long part 2051L and a short part 2051R is used. Positioning in the width direction with the outer piece 202 and its fixing are more reliably performed.

[2. Modified example]
The above-described embodiments can be variously modified within the scope of the technical idea of the present invention. Examples of these modifications are shown below.

  In the first embodiment and the second embodiment described above, the outer piece 102 includes the locking pin 108, and the outer piece 202 includes the through hole 1023 for receiving the locking ring 209 and the locking pin 208. However, instead of the through-hole, a configuration in which the outer piece 102 or the outer piece 202 includes a bottomed hole that opens on the bottom surface side in FIG. 1 or FIG. 11 may be employed.

  Further, in the first embodiment described above, a so-called pivot pin having a structure in which the head portion 1082 and the coil spring 1083 are accommodated in the cylindrical casing 1081 as shown in FIG. However, various other types of locking pins having other structures in which the head portion is lowered by pressing can be used in place of the locking pins 108. For example, when the through-hole 1023 is a bottomed hole, a locking pin having a step pin structure with a coil spring as shown in FIG. 16 may be employed.

  Further, the locking pin 108 employed in the first embodiment described above has a structure in which the length is reduced only while the head portion is pressed from the outside with a predetermined force or more. Instead, for example, when the head portion is pressed from the outside with a predetermined force or more, the length is reduced, and after the force is released, the reduced length is maintained. A locking pin having a structure that extends so as to return to its original length when pressed with the above force may be used.

  In the second embodiment described above, the locking pin 208 is held in the locking ring 209 by being press-fitted into the locking ring 209, and is held in the through hole 1023 via the locking ring 209. However, a configuration may be employed in which it is inserted directly into the through hole 1023 and held in the through hole 1023 by press fitting or the like.

  Further, in the second embodiment described above, once the locking pin 208 is press-fitted into the locking ring 209, it is difficult to remove the locking pin 208. For example, as shown in FIG. A screw hole is provided in an end portion disposed on the opening side of 1023, a bolt or the like is screwed into the screw hole, and then the locking pin 208 is pulled out from the locking ring 209 via the screwed bolt or the like, thereby The pin 208 may be removable. Then, also in the band 2, the unit piece 20 for length adjustment can be attached and detached relatively easily.

  Further, the connecting pin 103 in the first embodiment and the second embodiment described above and the connecting pin 205 in the second embodiment do not necessarily have a two-piece configuration that fits each other. For example, a single rod-like body is used. Various other configurations such as a configuration in which the outer piece 202L and the outer piece 202R are fixed by caulking, press fitting, or the like can be employed.

  Further, instead of the connecting pin 105 (simple bar) in the first embodiment described above, a spring bar biased in a direction extending in the longitudinal direction may be used. In that case, the connecting pin, which is a spring bar, presses the cap 107 outward from the inside, and the effect of preventing backlash generated between the outer piece 102 and the cap 107 is brought about.

  In the above-described embodiment, the unit piece 10 or the unit piece 20 has a structure including three pieces of an outer piece, an inner piece, and an outer piece in the width direction, but the number of those pieces is three pieces. Not limited to. For example, like the left outer piece, the first inner piece, the second inner piece, the third inner piece, and the right outer piece, five pieces are alternately arranged in the width direction, and they are connected by a connecting pin. A unit piece having a different structure may be employed. Even in this case, the cap is covered with the right outer piece and the left outer piece so as to hide the end portions of the connecting pins exposed on the outer side surfaces of the right outer piece and the left outer piece, and the cap is inserted by the locking pin inserted from the bottom side. Is locked to the right outer piece or the left outer piece in the same manner as the above-described embodiment.

  Moreover, you may combine them, such as comprising one band by mutually connecting the band 1 in 1st Embodiment mentioned above, and the band 2 in 2nd Embodiment. For example, by adopting band 1 for the part of one band where the length is adjusted by the user and adopting band 2 for the other part, the length can be easily adjusted and carelessly. A suitable band in which the frame connection is not disconnected is realized.

  It is also within the scope of the technical idea of the present invention to partially exchange the components of the band 1 and the components of the band 2. For example, in band 1, by using the outer piece 202 instead of the outer piece 102 and using the connecting pin 205 composed of the long part 2051L and the short part 2051R instead of the connecting pin 105, the connection and release of the unit pieces are compared. Thus, a band that is easily connected and has a strong connection between the outer pieces 202 arranged in the width direction is realized.

  In addition, the shape, quantity, etc. which were demonstrated in embodiment mentioned above and a modification are illustrations, Comprising: The technical scope of this invention should not be interpreted limitedly by them.

  In the above description, the material of each component constituting the connecting piece assembly is not mentioned, but the material is not limited to, for example, metal or ceramics. For example, a metal such as stainless steel is used for a part that requires fine processing but cannot be seen from the outside after assembly (for example, the connecting pin 105), and a part that is visible from the outside (for example, the inner piece 101 or the cap 107). By using ceramics, it is possible to reduce the cost while maintaining the overall durability and luxury of the band.

  Since the band according to the present invention can be widely mass-produced, it can be used in the manufacturing industry of watches and the like, and since the band manufactured in the manufacturing industry is sold to general consumers, Contributes to the service industry.
