Definitions

  • ABSTRACT A process for the manufacture of a highly resilient and pliant expandable band, characterized in that an annealed resilient metallic wire is wound repeatedly and continuously into a band-shaped or endless structure composed of a series of closely adjacent coils having the same number of turns, for each coil, so that every other coil is wound from top to bottom or vice versa and the interposed coil between such every other coil is wound from bottom to top or vice versa; the structure thus obtained is then subjected to a compressive force from its periphery; wedge pins are then inserted into any desirable coils and trimmed in their shape; and the overall structure is then subjected to quenching treatment from a high temperature.

  • FIG. 14 is a plan view thereof
  • FIG. 15 is a perspective view showing the expandable band of FIGS. 13 and 14 applied for a watch bracelet
  • FIG. 16 is a plan view showing an arrangement of magnetic poles and compressed windings in the magnetic band formed from nonmagnetizable metallic wires,
  • FIG. 17 is a cross section thereof, taken on line A-A'.
  • FIG. 18 is a plan view showing an arrangement of the magnetic poles in the magnetic band and compressed windings prepared from magnetizable metallic wire, and
  • FIG. 19 is an explanatory view illustrating the mode of magnetization of the magnetizable wire structure shown in FIG. 18.
  • This invention relates generally to a process for the manufacture of an expandable band in a band shape or endless shape that is applied as a watch bracelet or a magnetic bracelet, and has for its object to provide a highly resilient and pliant product by applying a simple and efficient process.
  • the present invention resides in such a background that an annealed resilient metallic wire is wound repeatedly and continuously into a band-shaped or endless structure composed of a series of closely adjacent coils having the same number of turns for each coil, so that every other coil is wound from top to bottom or vice versa and the interposed coil between such every other coils is wound from bottom to top or vice versa; the structure thus obtained is then subjected to a compressive force from its periphery; wedge pins are then inserted into any desired coils and trimmed in their shape; and the overall structure is then subjected to quenching.
  • a resilient metallic band 1 made from stainless steel wire is coiled in a desired number of turns, forming the first coil la in starting from the top, by way of an example, as shown in FIG. 3. Then, the same steel wire 1 is coiled again in the same number of turns, forming the second coil lb in starting from the bottom. Further, the third coil 1c is wound from the same steel wire I in the same number of turns. In this way, the steel wire is coiled further continuously so as to provide a series of adjacent coils ld, le, 1]",
  • the coils of FIG. 3 may be considered as being formed starting from the left and progressing toward the right in FIG.
  • the coil la is formed before the coil lb, and so on, with the convolutions of each coil being wound in a clockwise direction as viewed from above in FIG. 3, and it will be noted that the coils are arranged alternately to form a series of outer coils 1a, 1c, 1e, and inner coils lb, 1d, 1 f, with the continuous wire progressing from the top convolution of coil la to the-bottom convolution of coil lb, from the top convolution of coil 1b to the bottom convolution of coil 10, and so on, so that if the series of alternating inner and outer coils are considered as having corresponding opposed ends, it will be seen that the wire progresses from one of the opposed ends of an outer coil to the opposite opposed end of an adjacent inner coil, and then from the opposed end of the latter inner coil to the opposite end of the next outer coil, and so on.
  • the wire portions which interconnect the adjacent coils are arranged in such a way that at one of the series of inner or outer coils the wire portions cross each other while extending to the next adjacent coils while considered at the other series of inner or outer coils, the wires at the opposed ends of each coil diverge from each other while progressing to the next adjacent coils.
  • the wire portions which interconnect the adjacent coils are arranged in such a way that at one of the series of inner or outer coils the wire portions cross each other while extending to the next adjacent coils while considered at the other series of inner or outer coils, the wires at the opposed ends of each coil diverge from each other while progressing to the next adjacent coils.
  • FIGS. 11 and 12 show a product which has been completed following the step of compression.
  • FIG. 2 shows thus obtained expandable band as mounted to a wrist-watch.
  • An elastic nonmagnetic metal wire such as stainless steel wire
  • the endless structure thus obtained is then subjected as before to the step of compression.
  • a number of permanent magnet pieces 3 are forced into any desired coils, instead of wedge or retaining pins 2.
  • the ends of the permanent magnet pieces 3 are enlarged in their diameters by upsetting so as to provide flanges 3'. In this way, the permanent magnet pieces 3 are held in position and prevented from accidental disengagement.
  • the overall structure is then subjected to quenching treatment.
  • a north pole may be followed by a south pole or two successive north poles may be followed by two successive south poles.
  • FIG. 15 shows a product completed according to this process.
  • the expandable band preparedby the present process is made in its entirety from a fine metal wire about 0.1 to 0.2 mm diameter.
  • the band itself is highly pliant and resilient.
  • the expandable band is safeguarded against collapse.
  • the expandable band is produced by the process of repeatedly coiling a single metallic wire, a considerable saving will be attained in the man power required for the manufacture, thus resulting in high operational efficiency.
  • the production costs of the expansible band can be considerably reduced.
