It is possible.

  Hereinafter, the wearable band 1 according to the present invention will be described in detail, and then each member and the assembling method thereof will be described in detail. The wearable band 1 according to the present invention includes, in the illustrated embodiment, a flexible plate 5, a band body 2 attached to the upper surface side of the flexible plate 5, and two sheets attached to the inner surface side of the band body 2. Flexible band-like plates 3A and 3B, and lock mechanisms 4A and 4B provided at both ends of the band main body 2, respectively. Among these, the flexible strips 3A and 3B and the lock mechanisms 4A and 4B are for maintaining the curved state when the band body 2 is curved and used in the embodiment.

  The flexible plate 5 includes a main flexible plate 5a and sub-flexible plates 5b and 5c, and is made of stainless steel such as SUS304H having flexibility. The band body 2 includes end pieces 21A and 21B provided at both ends thereof, a plurality of intermediate pieces 22A to 22I, 23A and 23B arranged in sequence between them, and a plurality of connecting pieces 24A to 24J. The plurality of intermediate pieces 22A to 22I, 23A, and 23B are connected to each other by pivot pins 7 and 7 through the plurality of connection pieces 24A to 24J so as to be rotatable within a predetermined angle range. Yes. In the illustrated embodiment, the end piece 21A and the intermediate piece 22A are connected by the sub-flexible plate 5b, and similarly, the end piece 21B and the intermediate piece 22B are connected by the sub-flexible plate 5c. In this embodiment, among the above members, the end pieces 21A and 21B, the intermediate pieces 22A to 22I, 23A and 23B, and the connecting pieces 24A to 24J are made of a synthetic resin such as POM (polyacetal), and are pivotally supported. 7, 7 (and guide pins 8A and 8B and presser pins 9A and 9B described later) are made of stainless steel such as SUS304H, for example. However, it is not necessarily limited to these materials. In the illustrated embodiment, small intermediate pieces 22A to 22I and large intermediate pieces 23A and 23B are used as the intermediate piece. As described above, the large intermediate pieces 23A and 23B other than the small intermediate pieces 22A to 22I are provided with a relatively wide area that does not bend, and it is easy to attach an unbent member such as a circuit board or a battery. It is to do.

  The flexible strips 3A and 3B do not necessarily need to be composed of two sheets, but are made of a flexible metal such as thin stainless steel, respectively, and the main portions 301 and 321 and the inwardly extending portions 302 and 303, respectively. 322, 323, outwardly extending portions 304, 305, 324, 325, and the fixing pin holes 308, 309, 328, 329 provided in the respective inner end portions 306, 307, 326, 327, the band The small intermediate piece 22F angled to the center of the main body 2 is fixed by fixing pins 6a and 6a. That is, the fixing pins 6a and 6a are inserted into the fixing pin holes 308 and 309 of the flexible strip plate 3A from the fixing pin holes 53b and 53c of the main flexible plate 5a through the fixing pin holes 22f and 22h of the small intermediate piece 22F. Further, after being inserted into the fixing pin holes 328 and 329 of the flexible strip plate 3B overlaid thereon, the tips of the two flexible strip plates 3A and 3B are deformed by means such as caulking. The respective inner end portions 306, 307, 326, 327 are fixed to the inner surface of the small intermediate piece 22F. The flexible strip-shaped plates 3A and 3B are provided so as to extend outward in the longitudinal direction along the inner surface of the band main body 2 from this fixed angle, and their outer end portions 310, 311, 330 and 331 are provided on the band main body 2. It has a length until it reaches the angle of the end pieces 21A, 21B. The range from the fixed angle of the inner end portions 306, 307, 326, 327 of each flexible strip-shaped plate 3A, 3B to the outer end portions 310, 311, 330, 331 is not fixed to the band body 2, If it says from the inner surface of the band main body 2, it will be in the state which floated. Therefore, when the band main body 2 is curved toward the inner surface, the length along the inner surface of the band main body 2 is reduced, whereas the flexible belt-like plates 3A and 3B themselves bent together with the band main body 2 are fixed. Since the length in the range from the portion to the outer end portions 310, 311, 330, 331 does not substantially change, the outer end portions 310, 311, 330 of the flexible strips 3A, 3B are caused by the difference in length. 331 slides along the inner surface of the band body 2 so as to advance outward in the longitudinal direction. Conversely, when restoring the band main body 2 from the curved state to the flat state, the outer end portions 310, 311, 330, 331 of the band main body 2 return to the original angle along the inner surface of the band main body 2. Slide inward along the longitudinal direction.

In this case, the outer ends 310, 311, 330, and 331 of the flexible strips 3A and 3B that have advanced toward the end pieces 21A and 21B as described above are constrained to be held at the angles, and the band body 2 The curved state (and hence the curved state of the wearable band 1) is maintained. In the illustrated embodiment, the lock mechanisms 4A and 4B are composed of a pair of locking members 41A and 41B attached to the end pieces 21A and 21B, respectively, and outer ends (free ends) of the flexible strips 3A and 3B. Part) 310, 311, 330, 331, and a pair of locked members 42 </ b> A, 42 </ b> B attached by fixing pins 44, 44 (see FIGS. 4, 5), the pair of locking members 41 </ b> A, 41B is urged in a direction toward the locked members 42A and 42B by elastic means 43 and 43 such as coil springs. Engaging convex portions 411 and engaging concave portions 412, 413 (see FIGS. 5 and 11) are formed on the locking members 41A and 41B, while the locking members 41A are formed on the locked members 42A and 42B. 41B, engaging concave portions 422 and 423 and engaging convex portions 421 (see FIG. 5 and FIG. 12) that fit into the engaging convex portions 411 and engaging concave portions 412 and 413 are formed. When the predetermined amount of bending toward the inner surface side is made, the engaging convex portion 411 of the locking members 41A and 41B and the engaging concave portion 422 of the locked members 42A and 42B engage with each other, and the locking member The locked state of 41A, 41B and the engaged members 42A, 42B is created, and the curved state of the band body 2 is maintained. In order to unfold the wearable band 1 from the curved state as shown in FIG. 2 and return it to the flat state, when a slightly strong force is applied to the wearable band 1 (band body 2) to flatten the wearable band 1, The engagement protrusions 411 of the locking members 41A and 41B and the engagement recesses 422 of the locked members 42A and 42B are released, the locked state is released, and the wearable band 1 is restored to its original flat shape. It will be possible to return to the expanded state.

  The locking members 41A and 41B are connected to the end piece 21A by guide pins 8A and 8B (FIG. 4) including two pins 81 and 82 inserted through the pin insertion holes 414 and 415 (see FIG. 11). , 21B is slidably held along these guide pins 8A, 8B. Further, the locked members 42A and 42B have the flexible pins by the guide pins 8A and 8B including the two pins 81 and 82 inserted into the pin insertion holes 424 (FIG. 12) having a long cross section.

  Hereinafter, the configuration of each member and the like will be described in more detail. Since the small intermediate pieces 22A to 22I of the band main body 2 have the same configuration, only the small intermediate piece 22A will be described here, and the indication symbols in the drawings also prevent the complication of the drawing. Only the intermediate piece 22A will be described. Similarly, the large intermediate pieces 23A and 23B have the same configuration, and the connecting pieces 24A to 24J have the same configuration, so only one of them will be described.

  The flexible plate 5 includes a main flexible plate 5a and sub-flexible plates 5b and 5c. As shown in FIG. 4, the main flexible plate 5a has a plate portion 53a and a plurality of fixing pin holes 53b to 53d. Similarly, the sub flexible plates 5b and 5c also have plate portions 51a and 52a and a plurality of fixing pin holes 51b to 51e and 52b to 52e.

  The small intermediate piece 22A of the band body 2 is configured as shown (the small intermediate piece 22A is shown as a single item in FIG. 7), and includes a main body portion 22a, edge rising portions 22b and 22c, and a pin-through protrusion 22d. 22e, fixing pin holes 22f-22h, fitting convex portions 22i, 22j, fitting concave portions 22k, 22l, pin insertion holes 22m-22p, communication grooves 221n, 222n, 221o, 222o, and inclined side surfaces 22q, 22r. In the case of this embodiment, the small intermediate piece 22A is manufactured by injection molding or the like of a synthetic resin such as POM as described above. In that case, for forming the pin insertion holes 22m to 22p provided in the pin passage protrusions 22d and 22e, in order to facilitate the forming operation, the communication grooves 221n and 221o are formed on the outer surface side of the main body portion 22a, Similarly, the communication grooves 222n and 222o are formed on the inner surface side, and the pin insertion holes 22m to 22p are formed by making these communicate with each other. Inclining the edge rising portions 22b and 22c and the inclined side surfaces 22q and 22r of the pin-through protrusions 22d and 22e [see FIGS. 7 (d) to (g)] causes the bending limit angle of the band body 2 to be inclined. This is to make it stipulated. The fitting projections 22i, 22j and the fitting recesses 22k, 22l are fitted with similar fitting projections or fitting recesses of the adjacent small intermediate piece 22A or large intermediate pieces 23A, 23B, It serves to prevent twisting of the main body 2 and ensure the stability of the shape of the band main body.

  The large intermediate piece 23A of the band body 2 is configured as shown (the large intermediate piece 23A is shown as a single item in FIG. 8), and includes a main body portion 23a, edge rising portions 23b and 23c, and a pin-through protrusion. Portions 23d to 23g, fixing pin holes 23h and 23h, fitting convex portions 23i and 23j, fitting concave portions 23k and 23l, pin insertion holes 23m to 23t, communication grooves 231n, 231o, 231r, 231s, and 232n 232o, 232r, 232s and inclined side surfaces 23u, 23v. In the case of this embodiment, this large intermediate piece 23A is also produced by injection molding or the like of a synthetic resin such as POM. In the case, the pin insertion holes 23n, 23o, 23r, and 23s provided in the pin passage protrusions 23d to 23g are formed on the outer surface side of the main body portion 23a in order to facilitate the forming operation. The pin insertion holes 23n, 23o, 23r, and 23s are formed by communicating the communication grooves 231n, 231o, 231r, and 231s with the communication grooves 232n, 232o, 232r, and 232s on the inner surface side. The reason for inclining the edge rising portions 23b and 23c and the inclined side surfaces 23u and 23v of the pin passage protrusions 23d to 23g is to define the bending limit angle of the band body 2.

  The end piece 21A (21B) of the band body 2 is configured as shown (the end piece 21A is shown as a single item in FIG. 9), and includes a main body portion 21a, edge rising portions 21b and 21c, and a pin-through projection. 21d, fixed pin holes 21e and 21g, fitting recesses 21h and 21i, pin insertion holes 21j and 21k, communication grooves 21l to 21n, and inclined side surfaces 21o and 21p. In the case of this embodiment, the end piece 21A is also produced by injection molding or the like of a synthetic resin such as POM. In the case, the pin insertion holes 21j and 21k provided in the pin passage protrusion 21d are formed in the same manner as described above, in order to facilitate the forming operation, the communication groove 21n on the outer surface side of the main body 21a, and the inner surface The pin insertion holes 21j and 21k are formed by making the side communication grooves 21l and 21m communicate with each other. The reason why the inclined side surfaces 21o and 21p of the edge rising portions 21b and 21c are inclined is to define the bending limit angle of the band main body 2.

  The connecting piece 24A of the band body 2 is configured as shown (the connecting piece 24A is shown as a single item in FIG. 10), and has a main body portion 24a and two pin insertion holes 24b and 24c having an oval cross section. Yes. The pin insertion holes 24b and 24c have an oval cross section. The two axial support pins 7 and 7 inserted through these holes are respectively connected to two small intermediate pieces and large intermediate pieces adjacent to each other. This is because the interval between the two shaft support pins 7 and 7 is inserted to correspond to change according to the bending operation of the wearable band 1.

  Next, a method for connecting the small intermediate piece and the large intermediate piece or connecting the small intermediate pieces to each other in the present embodiment will be described. When connecting the small intermediate piece 22A and the large intermediate piece 23A, as shown in FIG. 6 [see also FIG. 2 (b), FIG. 4 and FIG. 5], the small intermediate piece 22A and the large intermediate piece The pieces 23A are placed with their inner surfaces facing upward, and a pair of pin-through protrusions 22d, 22e on the small intermediate piece 22A and a pair of pin-through protrusions 23d, 23e on the large intermediate piece 23A The connecting piece 24A is set between them.

It can be attached with.

  The wearable band 1 is used without being bent and placed on a desk or table in a flattened unfolded state as shown in FIG. Or can be operated as a touch panel. In addition, as shown in FIG. 1, the wearable band 1 can be used as a smartphone, a physical condition monitor, a playground equipment, etc. in a state where the wearable band 1 is curved in a C shape and attached to the wrist, arm, ankle or the like. In the case of using such a curved shape, as shown in FIG. 1C, when the wearable band 1 is curved by a predetermined amount, the inclined side surfaces 22q and 22r of the small intermediate pieces 22A to 22I and the large intermediate piece 23A are obtained. , 23B and the inclined side surfaces 21o, 21p of the end pieces 21A, 21B come into contact with each other, reach the bending limit angle, and no longer bend. Until this state is reached, the outer end portions 310, 311, 330, and 331 (FIG. 4) of the flexible strips 3 </ b> A and 3 </ b> B slide along the inner surface of the band body 2 so as to advance in the longitudinal direction. At that time, as shown in FIG. 5, the locked members 42 </ b> A and 42 </ b> B attached to the outer ends 310 and 311 of the outwardly extending portions 304 and 305 of the flexible strip 3 </ b> A are angled as shown in FIG. To the angle shown in FIG. 5 (b) and is locked by the locking members 41A and 41B to be locked, and the bending state at the bending limit angle is maintained. That is, when the band main body 2 is bent until the bending limit angle is reached, the engaging convex portions 411 of the locking members 41A and 41B and the engaging concave portions 422 of the locked members 42A and 42B are engaged with each other. Thus, the locked state of the locking members 41A and 41B and the locked members 42A and 42B is created. In order to return the wearable band 1 from the curved state to the flat state as shown in FIG. 2, if a slightly strong force is applied to the wearable band 1 (band body 2) to flatten the wearable band 1, The engagement convex portion 411 of the stop members 41A and 41B and the engagement concave portion 422 of the locked members 42A and 42B are disengaged, the locked state is released, and the wearable band 1 is returned to the original flat state. Can be returned. The same applies to the function of the lock mechanism 4B for the other flexible strip 3B.

  Although the bull band 1 according to the present invention is not shown in the drawing, the locking mechanism has a convex and concave fitting between the flexible belt-like body 3A and each piece so that the convex and concave portions are detachable from each other. The lock mechanism of the configuration, or the lock mechanism of other known configurations, and the lock mechanism and the friction mechanism are used together to maintain a predetermined bending angle or a flat deployed state. Can be configured. When implemented in this manner, the display plate can be placed on a desk in a flat state, or can be stably operated while being held by hand, and can be used at various bending angles.
