  The first winding shaft 13 </ b> R is formed in a cylindrical shape, and one end thereof is integrally connected to the base 11 on one side surface of the base 11. The first winding shaft 13 </ b> R is formed such that its radial dimension is smaller (thinner) than the base 11.

  Hereinafter, the central axis of the first winding shaft 13R will be simply referred to as the central axis C, and the axial direction of the central axis C will be simply referred to as the axial direction. In FIG. 1, the axial direction of the central axis C is a horizontal direction, but the axial direction of the central axis C when using the optical fiber winder 10 of the present embodiment is not particularly limited. For example, the vertical direction and other directions may be used.

  The first rotating portion 14 </ b> R is a member provided to be rotatable relative to the base 11 around the central axis C.

  As shown in FIG. 4A, the first rotating portion 14R is formed in a bottomed cylindrical shape with one end closed, and its outer diameter dimension is larger than that of the winding shaft 13R. 14 R of 1st rotation parts have accommodated the area | region by the side of the other end part of 13 R of 1st winding shafts in the internal diameter side in the area | region of the opening end side. The first rotating portion 14R is connected to the first winding shaft 13R so as to be rotatable around the central axis C.

  The first sliding groove 15R is a sliding support portion that supports the excessive portion Fb of the optical fiber F so as to be slidable with respect to the first rotating portion 14R.

  The first sliding groove 15R is a groove formed on the outer peripheral surface of the first rotating portion 14R, and the surplus portion Fb of the optical fiber F is disposed between the opposing side surfaces of the first sliding groove 15R. The groove width of the first sliding groove 15R is such that there is a minute gap between the side surface of the first sliding groove 15R and the outer peripheral surface of the surplus portion Fb to allow the surplus portion Fb to slide on the rotating portion 14R. It is set to be formed.

  Here, the first sliding groove 15R has a V-shape in which one side surface of the pair of opposing side surfaces is substantially parallel to the axial direction and the other side surface is inclined with respect to the axial direction. The groove width is formed so as to be wider on the base 11 side (see FIG. 3). Hereinafter, the side surface of the first sliding groove 15R that is inclined in the axial direction will be referred to as a first inclined surface 15Ra.

  The optical fiber winder 10 of the present embodiment has a second winding on the opposite side of the base 11 with respect to the first winding shaft 13R, the first rotating portion 14R, and the first sliding groove 15R described above. A take-up shaft 13L, a second rotating portion 14L, and a second sliding groove 15L are provided.

  Hereinafter, matters common to the first take-up shaft 13R and the second take-up shaft 13L will be referred to as the take-up shaft 13 as appropriate. The same applies to the rotating portion 14 and the sliding groove 15.

  The second winding shaft 13L is formed in substantially the same outer shape as the first winding shaft 13R, and one end thereof is connected to the other side surface of the base 11 (the side opposite to the first winding shaft 13R). ing. The central axis C of the first winding shaft 13R and the central axis of the second winding shaft 13L substantially coincide.

  Here, each of the first winding shaft 13R and the second winding shaft 13L winds the excess portion Fb of the optical fiber F around its outer peripheral surface, but the winding direction of the excess portion Fb (hereinafter simply referred to as winding). Taking direction) is the opposite direction around the central axis C. Specifically, the winding direction of the surplus portion Fb with respect to the first winding shaft 13R is the direction of arrow A shown in FIG. 5B, and the winding direction with respect to the second winding shaft 13L is FIG. It is the direction of arrow B shown in b).

  The second rotating portion 14L is a member formed with substantially the same outer shape as the first rotating portion 14R, provided on the other end side of the second winding shaft 13L, and centered with respect to the second winding shaft 13L. It is connected so as to be rotatable around the axis C.

  The second sliding groove 15L is a groove formed on the outer peripheral surface of the second rotating portion 14L, and functions in the same manner as the first sliding groove 15R.

  However, as shown in FIG. 3, the side surface (hereinafter referred to as the second inclined surface 15La) provided in the second sliding groove 15L so as to be inclined in the axial direction is around the axis with respect to the first inclined surface 15Ra. It is formed on the opposite side surface.

  The urging spring 16 is an urging portion that urges the first rotating portion 14 </ b> R and the second rotating portion 14 </ b> L in the winding direction with respect to the base 11.

  As shown in FIG. 4B, the urging spring 16 is a spiral spring (spring spring) housed on the inner diameter side of the base portion 11. At both ends of the spiral spring, shaft-shaped members 16a and 16b extending substantially parallel to the central axis C are provided, respectively, and one shaft-shaped member 16a provided at the end on the center side of the spiral spring. Are mechanically connected to the first rotating part 14R and the other shaft-like member 16b to the second rotating part 14L, respectively.

  Thus, for example, when the first rotating portion 14R is rotated in the direction opposite to the arrow A, the first rotating portion 14R is rotated in the arrow A direction (winding direction) by the urging force of the urging spring 16. Further, when the second rotating portion 14L is rotated in the direction opposite to the arrow B, the second rotating portion 14L is rotated in the arrow B direction (winding direction) by the urging force of the urging spring 16.

  The cover 17 is a member formed in a cylindrical shape, and is a housing portion that houses the base portion 11, the winding shaft 13, and the rotating portion 14 on the inner diameter side thereof. A minute gap is provided between the cover 17 and the rotating unit 14 so as not to prevent the rotation of the rotating unit 14.

  The dimension along the axial direction of the cover 17 is, for example, 80 mm. The outer diameter of the cover 17 is, for example, 35 mm.

  Next, a method of using the optical fiber winder 10 will be described by taking as an example a case where the surplus portion Fb is wound around the first winding shaft 13R. At this time, a region other than the region actually wound around the optical fiber winder 10 in the indoor lead-in region Fb is passed through the inner diameter side of the cover 17 in advance.

  First, as shown in FIG. 5A, a part of the surplus portion Fb is sandwiched between the fixing portions 12, thereby fixing the portion to the base portion 11.

  Then, as shown in FIG.5 (b), the surplus part Fb is wound around the 1st winding shaft 13R. At this time, for example, the user of the optical fiber winder 10 holds and fixes the base 11 with one hand and winds the surplus portion Fb around the first winding shaft 13R with the other hand (FIG. 5 ( c)).

  In addition to the above winding method, the surplus portion Fb may be wound around the first winding shaft 13R by the following method.

  That is, in the same manner as in the above method, after a part of the surplus portion Fb is fixed to the fixing portion 12, the first sliding portion provided on the first rotating portion 14R has a region closer to the first rotating portion 14R than this portion. Insert into the groove 15R.

  Next, the user rotates the first rotating portion 14 </ b> R in the winding direction A with respect to the base portion 11. When the first rotating portion 14R rotates in the winding direction A, the position of the first sliding groove 15R around the central axis C with respect to the fixed portion 12 changes, so that the surplus portion Fb is more in the first rotating portion than the fixed portion 12. The region on the 14R side is drawn into the take-up shaft 13R side while sliding in the slide groove 15R, and taken up on the first take-up shaft 13R in the same direction (winding direction) as the rotation direction of the first rotating portion 14R. (See FIG. 5 (c)).

  When the optical fiber F on the second rotating portion 14L side of the fixed portion 12 is wound around the second winding shaft 13L, the winding direction B of the optical fiber F is wound around the first winding shaft 13R. Except for the reverse point, it is almost the same as the above (see FIG. 5C).

  Finally, as shown in FIG. 5D, the cover 17 is put on the base 11, the winding shaft 13, and the rotating part 14. As a result, the surplus portion Fb of the optical fiber F can be collected in a compact manner.

  Here, for example, when a person gets caught in the indoor drawing-in area Fa of the optical fiber F in this state, the surplus portion Fb is changed according to this tension (denoted with reference numeral T in FIG. 6). It is pulled out from the winder 10.

  Hereinafter, the operation of the optical fiber winder 10 when the tension T acts on the optical fiber winder 10 from both sides in the central axis C direction will be described with reference to FIG. FIG. 6 shows the optical fiber winder 10 with the cover 17 omitted for easy understanding.

  The surplus portion Fb is slidably supported by the rotating portion 14 in the sliding groove 15, and the rotating portion 14 including the sliding groove 15 is rotatably connected to the winding shaft 13.

  Here, the first inclined surface 15Ra and the second inclined surface 15La provided respectively in the first sliding groove 15R and the second sliding groove 15L are surplus when the axial tension T acts on the indoor drawing area Fa. It is pressed by the part Fb and functions as a pressed surface. When the inclined surfaces 15Ra and 15La are pressed, the rotating portion 14 rotates in the direction opposite to the winding direction against the urging force of the urging spring 16 (see FIG. 6B). Thus, the excess portion Fb wound around the winding shaft 13 is smoothly unwound from the first winding shaft 13R and the second winding shaft 13L, respectively.

  Further, when the tension T is relaxed by unwinding the surplus portion Fb, the rotating portions 14R and 14L are rotated in the winding directions A and B, respectively, by the urging spring 16 (see FIG. 6C).

  Thereby, the surplus portion Fb is wound around the winding shaft 13 again, and in this winding state, the slackness of the surplus portion Fb wound around the winding shaft 13 by the biasing spring 16 is prevented (FIG. 6). (See (d)).

  As described above, according to the optical fiber winder of the first embodiment, the following effects can be obtained.

(1) The optical fiber winder 10 can wind up the excess portion Fb of the optical fiber F around the winding shaft 13 and accommodate it in a compact manner. Thereby, the possibility that a person or an object is caught in the indoor drawing-in area Fa of the optical fiber F is reduced.

(2) The optical fiber winder 10 can smoothly unwind the surplus portion Fb of the optical fiber F from the winding shaft 13 when the tension T acts on the indoor drawing area Fa of the optical fiber F. Therefore, disconnection of the indoor lead-in area Fa or excess portion Fb due to the tension T can be prevented, and communication failure of the Internet line formed by the optical fiber F can be prevented.

(3) In the optical fiber winder 10, since the biasing spring 16 biases the rotating portion 14 in the winding direction, the slack of the surplus portion Fb is prevented in the state of being wound around the winding shaft 13. .

(4) Since the optical fiber winder 10 includes the pair of winding shafts 13 with the base 11 interposed therebetween, even if the surplus portion Fb is long, it can be reliably wound.

(5) Since the optical fiber winder 10 includes the cover 17 that covers the winding shaft 13 and the rotating portion 14, it is possible to prevent the sheath of the surplus portion Fb from being damaged. Moreover, the appearance of the optical fiber winder 10 is also improved.

  FIGS. 8A and 8B are views showing an optical fiber winder according to the third embodiment. FIGS. 8A and 8B are an external perspective view and a cross-sectional view, respectively.

  Similarly to the second embodiment, the optical fiber winder 210 according to the third embodiment has a two-piece structure in which a cover serving as a housing portion includes a first cover 117R and a second cover 117L. 118 is provided.

  Moreover, although the biasing spring 16 of the optical fiber winder 10 of the first embodiment is provided to the first rotating portion 14R and the second rotating portion 14L via the shaft-like members 16a and 16b, On the other hand, the optical fiber winder 210 according to the third embodiment includes a first biasing spring that biases the first rotating portion 14R and the second rotating portion 14L independently of each other in the winding direction with respect to the base 11. 216R and a second urging spring 216L are provided.

  As shown in FIG. 8B, the first biasing spring 216R has a shaft-like member 216Ra provided at one end thereof connected to the first rotating portion 14R, and the other end 216Rb connected to the inner periphery of the winding shaft 13R. It is fixed to the surface. The second urging spring 216L functions in substantially the same manner as the first urging spring 216R, one end is connected to the second rotating portion 14L, and the other end is fixed to the inner peripheral surface of the winding shaft 13L. The configuration of the second urging spring 216L is shown in parentheses in FIG. 8B, and the illustration thereof is omitted.

  The rotating unit 14 (14R, 14L) of the first embodiment rotates (and rotates) in conjunction with the rotation of one, whereas the optical fiber winder 210 of the third embodiment, for example, When the tension TR acts on the indoor pull-in area FaR on the first rotating portion 14R side as viewed from the base 211, only the first rotating portion 14R is in the direction of arrow -A (the winding direction A in FIG. 8A). Only the optical fiber FR rotated in the opposite direction) and wound around the first winding shaft 13R is unwound from the optical fiber winder 210.

  Further, for example, when the tension TL is applied to the indoor pull-in area FaL on the second rotating unit 14L side as viewed from the base 211, only the second rotating unit 14L rotates in the arrow -B direction in FIG. Only the optical fiber FL wound around the second winding shaft 13L is unwound from the optical fiber winder 210.

  As described above, according to the optical fiber winder 210 of the third embodiment, since the rotating unit 14 on the side where the tension T does not act does not rotate, only in one indoor drawing area Fa (for example, the indoor drawing area FaR). When the tension is applied, the optical fiber F on the side where the tension T does not act (for example, the indoor drawing area FaL) can be prevented from being wound around the winding shaft 13. For this reason, even if it is a case where the optical fiber winder 310 is fixed to a wall etc. with the magnet 118, the disconnection of the surplus part Fb can be prevented reliably.

[Fourth Embodiment]
Next, a description will be given of a fourth embodiment of an optical fiber winder to which the present invention is applied.
FIG. 9 is an exploded perspective view showing the optical fiber winder of the fourth embodiment.
FIG. 10 is a perspective view of a main part of the optical fiber winder shown in FIG.
FIG. 11 is a diagram illustrating the operation of the optical fiber winder illustrated in FIG. 9.

  In the optical fiber winder 310 of the fourth embodiment, a spiral groove is formed on the outer peripheral surface of the first windup shaft 313R. The spiral groove functions as a screw groove.

  The first rotating portion 314R includes a first moving portion 314aR having a projection (not shown) that is screwed into a spiral groove provided on the first winding shaft 313, and a first moving portion formed in a cylindrical shape on the inner diameter side thereof. A first cylinder 314bR that accommodates 314aR is provided.

  In addition, a second rotating part 314L is provided on the opposite side of the base 311 with respect to the first rotating part 314R. Since the structures and functions of the first rotating unit 314R and the second rotating unit 314L are substantially the same, the first rotating unit 314R on the first winding shaft 313R side will be described below.

  The first moving part 314aR is formed in an annular shape, and the first winding shaft 313R passes through the inner diameter side thereof. The first moving part 314aR has a thread-like protrusion (not shown) that is screwed into the spiral groove on the inner peripheral surface thereof. Further, the first moving part 314aR includes a pair of protrusions 314cR provided on the outer peripheral surface thereof so as to protrude to the outer diameter side. One of the protrusions 314cR is formed on the opposite side to the other with the first winding shaft 313R interposed therebetween.

  The first moving part 314aR has a first sliding groove 315R that functions in the same manner as the first sliding groove 15R of the first rotating part 14R of the first embodiment.

  The first cylindrical body 314bR includes a set of fitting grooves 314dR that are fitted to the protrusions 315cR of the first moving portion 314aR on the inner peripheral surface thereof. These fitting grooves 314dR are provided in parallel to the axial direction of the first winding shaft 313R. When the first moving portion 314aR rotates around the first winding shaft 313R, the first cylindrical body 314bR is In conjunction with this, it rotates around the first winding shaft 313R. The first cylinder 314bR also functions as a housing portion that covers the first winding shaft 313R.

  Further, as shown in FIG. 10, a first spiral spring 316 </ b> R is provided between the first cylinder 314 b </ i> R and the base 311. The first spiral spring 316R is a first biasing portion that biases the first cylindrical body 314bR in the winding direction A. Between the second cylinder 314bL and the base 311 is provided a vortex second winding spring 316L (not shown) that functions as a second urging portion.

  Next, operation | movement of the optical fiber winder 310 of 4th Embodiment is demonstrated using FIG.

  As shown in FIG. 11A, the surplus portion Fb of the optical fiber F is wound around the winding shaft 313 of the optical fiber winder 310. In this state, for example, when the tension T acts on the indoor pull-in area Fa of the optical fiber F on the first rotating unit 314R side, the first moving unit 314aR performs the first sliding as shown in FIG. The groove 315R is pressed by the surplus portion Fb and rotates around the first winding shaft 313R. By this rotation, the first moving unit 314aR is guided by the spiral groove formed on the first winding shaft 313R and approaches the base 311 side as shown in FIG. 11C. Further, the first cylinder 314bR also rotates in conjunction with the first moving part 314aR.

  When the tension acting on the optical fiber F is relaxed, as shown in FIG. 11E, the cylindrical body 314bR is rotated in the winding direction A by the first spiral spring 316R, and the first moving portion 314aR is The first cylinder 314bR rotates in conjunction with the first cylinder 314bR. At this time, the first moving unit 314aR moves in a direction away from the base 311. Note that a stopper (not shown) that functions as a stopper of the moving portion 314aR is provided at the tip of the first winding shaft 313R.

  As a result, the optical fiber F is again wound around the first winding shaft 313R, and the slack of the optical fiber F wound around the first winding shaft 313R is prevented.

  When tension is applied to the indoor retracting area Fa on the second winding shaft 313L side, the second moving portion 314aL moves in the axial direction with respect to the base portion 311 as in the above case.

  In the optical fiber winder 310 of the fourth embodiment, the excess portion Fb can be wound along the spiral grooves formed in the first winding shaft 313R and the second winding shaft 313L, respectively. The excess portion Fb can be prevented from being entangled, and the operation when winding the excess portion Fb and unwinding becomes smoother.

  In addition, since the distance between the moving portion 314aR and the base portion 311 changes according to the winding amount, the excess portion Fb can be reliably wound between the spiral grooves of the winding shaft 313.

  Next, the fifth embodiment of the optical fiber winder to which the present invention is applied will be described with respect to differences from the optical fiber winder of the first embodiment.

  FIG. 12 is a side view of the optical fiber winder of the fifth embodiment viewed from the central axis direction.

  In the optical fiber winder 410 according to the fifth embodiment, a cover 417 formed in a cylindrical shape is fixed to the base 11 (see FIG. 3). The cover 417 includes magnets 420 (420a and 420b). A total of two magnets 420 are provided on the cover 417, and one magnet 420a is provided on the opposite side of the cover 417 in the radial direction with respect to the other magnet 420b.

  The optical fiber winder 410 also includes two magnets 421 (421a, 421b) on the outer peripheral surface of the rotating unit 414. Among these magnets 421, one magnet 421a is provided on the opposite side of the rotating portion 414 in the radial direction with respect to the other magnet 421b. A minute gap is provided between the inner peripheral surface of the cover 417 and the outer peripheral surface of the rotating portion 414, and the magnet 420 provided on the cover 417 and the magnet 421 provided on the rotating portion 414 are separated from each other. ing.

  The optical fiber winder 410 according to the fifth embodiment does not include the biasing spring 16 as in the first embodiment, and the rotating portion 414 is rotatable with respect to the base portion 11.

  Similarly to the optical fiber winder 10 of the first embodiment, when the tension acts on the indoor drawing area Fa of the optical fiber F, the rotating portion 414 rotates in the optical fiber winder 410 of the fifth embodiment, and the surplus portion Fb is unwound from the winding shaft 13 (see FIG. 3), and the tension is relaxed.

  When the tension acting on the surplus portion Fb is relaxed and the force for rotating the rotating portion 414 is reduced, the rotating portion is caused by the attractive force acting between the magnet 420 provided on the cover 417 and the magnet 421 provided on the rotating portion 414. The rotation of 414 is limited, and the magnet 420 and the magnet 421 function as a limiting unit. Thus, after the tension is relaxed, the rotating portion 414 is rotated by inertia, and the excess portion Fb is further prevented from being unwound from the winding shaft 13.
