  Hereinafter, embodiments of the present invention will be described in detail. FIG. 1 is an exploded perspective view showing a string storage device 1 according to the present embodiment, and FIG. 2 is an assembled perspective view showing the string storage device 1. The string storage device 1 mainly includes a main body 3, a stopper 5, a guide 7, a reel 9, a spiral spring 13, a shaft 17, and the like.

  The main body 3 is a box-shaped member whose one surface is open. A plurality of holes for attaching members are provided at the attachment positions of the members described later. A hole 19 is provided above one side surface (left side surface in the figure) of the main body 3. The hole 19 is a hole through which the string 11 passes. A receiving plate 21 that is a receiving member for the string 11 is provided inside the main body 3 in the vicinity of the hole 19. The receiving plate 21 is a plate-like member.

  A stopper 5 is provided above the receiving plate 21 by a pin 22. Details of the stopper 5 will be described later. A hole 23 is provided in the upper surface of the main body 3 above the receiving plate 21. The hole 23 is a portion through which the lever 33 (FIG. 3) of the stopper 5 passes.

  A reel 9, a shaft 17, a spiral spring 13 and the like are provided below the inside of the main body 3. The shaft 17 is a rod-shaped member around which a spiral spring 13 is wound. An end portion of the innermost peripheral portion of the spiral spring 13 is joined to the shaft 17.

  The reel 9 is a member around which the string 11 is wound. A shaft hole 27 is provided at the center of the reel 9, and a recess 25 is provided around the shaft hole 27.

  The shaft 17 passes through the shaft hole 27 of the reel 9. The end of the shaft 17 passing through the reel 9 is joined and fixed to the main body 3. The diameter of the shaft hole 27 is slightly larger than the diameter of the shaft 17. Therefore, the reel 9 can rotate around the shaft 17 (shaft hole 27). When the shaft 17 penetrates, the spiral spring 13 is accommodated in the recess 25. Therefore, the outer diameter of the recess 25 is slightly larger than the outer diameter of the spiral spring 13 in a state where no force is applied, and the depth of the recess 25 is slightly deeper than the width (thickness) of the spiral spring 13. .

  The pressing plate 15 is a plate-like member having a hole in the center. The holding plate 15 is joined to the reel 9 in a state where the spiral spring 13 is accommodated in the recess 25. The shaft 17 passes through the hole of the pressing plate 21. That is, the spiral spring 13 is held in the recess 25 by the pressing plate 15.

  In a state where the spiral spring 13 is held in the recess 25, the end portion of the outermost peripheral portion of the spiral spring 13 is joined to the reel 9. That is, the outer peripheral part of the spiral spring 13 is joined to the reel 9, and the inner peripheral part of the spiral spring 13 is joined to the shaft 17. The shaft 17 is fixed to the main body 3, and the reel 9 is rotatable with respect to the shaft 17. Therefore, when the reel 9 is rotated with respect to the shaft 17, a rotational force is applied to the reel 9 in a direction to return to the original position by the spiral spring 13.

  The guide 7 is a rotating member that limits the direction of the string 11. The guide 7 is rotatably provided by a pin 8 on the side of the receiving member 21 and the like above the reel 9.

  The string 11 unwound from the reel 9 passes between the receiving plate 21 and the stopper 5 via the guide 7 and is led out of the main body 3 through the hole 19. A force is applied to the string 11 by the spiral spring 11 in the direction of unwinding. The string 11 may be rubber having some elasticity or any material such as cloth, resin, and leather.

  Next, details of the stopper 5 will be described. FIG. 3 shows the stopper 5. The stopper 5 includes a pressing member 29, a pin 22, a lever 33, a spring 35, and the like.

  The holding member 29 is a columnar member having an elliptical cross section. The pin 22 penetrates at a position eccentric from the center of the pressing member 29 to the end (longer diameter side). That is, the holding member 29 can rotate around the pin 22. A knurl 31 is provided on the side surface of the pressing member 29 opposite to the pin 22. The knurled 31 is for eliminating the slip with the string 11 and for securely fixing the string 11.

  A lever 33 is joined to the end of the pressing member 29 on the pin 22 side. The lever 33 is provided with a spring 35, and the lever 33 is always pulled toward one side. When the lever 33 is rotated with a force larger than the reaction force of the spring 35 (in the direction of arrow A in the figure), the pressing member 29 rotates around the pin 22. Since the pressing member 29 is oval and the position of the pin 22 is eccentric, the lower surface height of the pressing member 29 changes when the pressing member 29 rotates. When the lever 33 is released, the lever 33 is returned to its original position by the spring 35.

  Next, the operation of the string storage device 1 will be described. FIG. 4 is a view showing a state before the string storage device 1 is used. As described above, the string 11 is wound around the reel 9, one end is joined to the reel 9, and the other end is led out of the main body 3 from the reel 9 via the guide 7. Yes. The string 11 that has passed through the guide 7 passes through the upper surface of the receiving plate 21 from the guide 7 and becomes a straight line up to the hole 19 (FIGS. 1 and 2). Therefore, the string 11 is always led out in a certain direction.

  The string 11 receives a force in a direction (arrow B and C directions in the figure) that is always wound around the reel 9 by the spiral spring 13. If the cross-sectional area of the leading end of the cord 11 is made large in a state where the leading end of the cord 11 is led out from the hole 19, the cord 11 will not be wound into the main body 3. For example, the size of the tip of the string 11 may be made larger than the size of the hole 19 (FIGS. 1 and 2) by making the tip of the string 11 into a ring shape or the like.

  As described above, the stopper 5 provided on the receiving member 21 receives a force by the spring 35 (in the direction of arrow D in the figure), and the pressing member 29 rotates. As the pressing member 29 rotates, the lower surface position of the pressing member 29 moves downward, and the gap between the pressing member 29 and the receiving member 21 is reduced. When the gap between the lower surface of the pressing member 29 and the receiving plate 21 is smaller than the diameter of the string 11, the lower surface of the pressing member 29 is sandwiched between the string 11 and the receiving member 21 (in the direction of arrow E in the figure), and the string 11 is Fixed.

  In the state of FIG. 4, the string 11 is fixed by the stopper 5. Since the lower surface (knurl 31) of the holding member 29 bites into the string 11, when the string 11 is pulled out (in the direction of arrow F in the figure), the holding member 29 gradually presses down the string 11 (in the direction of arrow E in the figure). Since it rotates, the string 11 is not pulled out any more.

  When the cord 11 moves in the winding direction (arrow C direction in the figure), the pressing member 29 rotates in a direction to loosen the pressing of the cord 11, so that the cord 11 is easily made by the restoring force of the spiral spring 13. Rolled up.

  If the spring 35 is sufficiently strong, the pressing member 29 presses the string 11 sufficiently strongly in the state of FIG. 4, so that the movement in the direction of winding the string 11 (in the direction of arrow C in the figure) is also limited, It can also be fixed. Even if the spring 35 is not used, if the operation of the lever 33 is made completely manual and the lever 35 is fixed at an arbitrary position, the rotational position of the pressing member 29 can be arbitrarily set, and therefore the pressing force of the string 11 can be set. Can be adjusted arbitrarily. Therefore, if the string 11 is securely sandwiched by the pressing member 29, the string 11 can be fixed in both the unwinding direction (in the direction of arrow F in the figure) and the winding direction (in the direction of arrow C in the figure).

  FIG. 5 is a diagram illustrating a state in which the string 11 is pulled out from the string storage device 1. When the string 11 is pulled out, the lever 33 is operated to rotate the pressing member 29 (in the direction of arrow G in the figure), and a sufficient gap between the pressing member 29 and the receiving plate 21 may be taken. In this state, the string 11 receives only the reaction force of the spiral spring 13, but if the string 11 is pulled with a force equal to or greater than the reaction force, the string 11 can be easily pulled out from the string storage device 1 (in the directions of arrows H and I in the figure). be able to.

  FIG. 6 is a view showing a state where the stopper 5 is returned to the original state with the string 11 pulled out. When the lever 33 is released, the lever 33 returns to its original position by the spring 35 (in the direction of arrow K in the figure). Therefore, the string 11 is sandwiched between the pressing member 29 and the receiving plate 21, and the pressing member 29 bites into the string 11, so that the string 11 is not further drawn (in the direction of arrow L in the figure). As described above, if the force of the spring 35 is less than or equal to a predetermined value, the string 11 is rewound by the restoring force of the spiral spring 13 in the state shown in FIG.

  Next, the bicycle 40 using the string storage device 1 will be described. FIG. 7 is a view showing the bicycle 40. A loading platform 41 is provided at the rear of the bicycle 40, and the string storage device 1 is installed on an arm 43 in the vicinity of the loading platform 41. The string storage device 1 is securely fixed to the arm 43.

  First, as shown in FIG. 8A, a load 47 is placed on the loading platform 41. In this state, since the string 11 is accommodated in the string storage device 1, the string 11 does not come off the loading platform 41 and it is not necessary to unwind the string 11.

  Next, as shown in FIG. 8B, the string 11 is pulled out from the string storage device 1. At this time, the string 11 is pulled out while releasing the fixation of the string 11 by the stopper 5 of the string storage device 1. If the fixing of the stopper 5 is released, the string 11 can be easily pulled out from the string storage device 1.

  The end of the drawn string 11 is hooked on a hook 45 or the like on the rear side (the side far from the string storage device 1) of the loading platform 41. At this time, it is pulled out from the string storage device 1 longer than the string 11 necessary for fixing the luggage 47.

  Next, as shown in FIG. 8C, the string 11 is hung on the hook 45 of the loading platform 41, and the luggage 47 is securely fixed to the loading platform 41. When the strings 11 are fixed to the hooks 45 in order from the side farther from the string storage device 1, the excess strings 11 are sequentially wound around the string storage device 1. In the state where the luggage 47 is fixed to the end by the string 11, the extra length of the string 11 is wound up, and the unwinding of the string 11 is fixed by the stopper 5, so that the winding does not loosen. .

  Thus, according to the string storage device 1 according to the present embodiment, since the string 11 is stored in the string storage device 1, it is not necessary to unwind the string 11 when fixing the luggage to the loading platform. The string 11 is not unraveled when not in use.

  Further, in order to pull out the string 11, it is only necessary to release the fixing of the stopper 5, and the string 11 can be easily pulled out. After the luggage 47 is fixed by the string 11, the string 11 is unwound by the stopper 5. Therefore, the string 11 is not unwound and the baggage is not loosened.

  Since the string storage device 1 is provided with the guide 7, the pulling direction of the string 11 does not change depending on the remaining amount of the string wound around the reel 9, so that the winding and unwinding of the string 11 is smooth, The string 11 is not pulled in an unreasonable direction, the string 11 and the main body 3 do not interfere with each other, and the string 11 does not hurt.

  In particular, the string 11 is sandwiched between the pressing member 29 and the receiving plate 21, but the string 11 always passes through a certain position by the guide 7, so that the string 11 can be reliably fixed.

  Next, a string storage device 50 according to the second embodiment will be described. FIG. 9A is a view showing a string storage device 50 having a stopper 51. In the following embodiment, the same number as FIG. 1-2 is attached | subjected to the component which performs the same function as the string storage apparatus 1 shown in FIGS. 1-2, and the overlapping description is avoided. The string storage device 50 according to the second embodiment has substantially the same configuration as the string storage device 1, but differs in the following points. That is, the string storage device 50 is provided with a stopper 51 instead of the stopper 5 (and the receiving plate 21).

  FIGS. 9B and 9C are cross-sectional views taken along line MM in FIG. 9A, FIG. 9B shows a state in which the string 11 is fixed, and FIG. 9C shows a state in which the string 11 is fixed. It is a figure which shows the state which canceled.

  The stopper 51 includes a clip 55 and a lever 53 that opens and closes the clip 55. The clip 55 is arranged linearly with the guide 7 and the hole 19 (FIGS. 1 and 2) and is fixed to the main body 3. The clip 55 sandwiches the string 11 from the guide 7 toward the hole 19. When the lever 53 is not operated, the string 11 is pinched by the clip 55, and the string 11 is not unwound or taken up.

  When the string 11 is pulled out, as shown in FIG. 9C, the lever 53 is operated (in the direction of arrow N in the figure), and the clip 55 is released. In this state, since the string 11 is released from being fixed by the clip 55, the string 11 can be easily pulled out.

  After the necessary amount of the string 11 has been pulled out, the operation of the lever 53 is stopped, so that the clip 55 sandwiches the string 11 again by the restoring force of the clip 55, and the string 11 is fixed at that position. Similarly, when the drawn-out string 11 is rewound, the string 11 is released by operating the lever 53 and the string 11 is wound around the reel 9 by the restoring force of the spiral spring 13.

  Thus, according to the string storage apparatus 50 concerning 2nd Embodiment, the effect similar to the string storage apparatus 1 can be acquired. In particular, the string 11 in the unwinding direction and the winding direction can be reliably fixed by using the stopper 51 having the clip 55 for fixing the string 11.

  As mentioned above, although embodiment of this invention was described referring an accompanying drawing, the technical scope of this invention is not influenced by embodiment mentioned above. It is obvious for those skilled in the art that various changes or modifications can be conceived within the scope of the technical idea described in the claims, and these are naturally within the technical scope of the present invention. It is understood that it belongs.

  For example, although only a bicycle is cited as an example of use of the string storage device, it can be applied to a loading platform such as a motorcycle or a truck. Further, the attachment position of the string storage device 1 is not limited to the present embodiment, and the string storage device 1 may be attached anywhere as long as the luggage can be fixed. Moreover, although the string storage device is provided with the stopper 5 or the stopper 51, it is not limited to this form. Other means may be used as long as the string 11 can be fixed at an arbitrary position. The strap storage device is provided with a stopper 5 or the like. However, when the strap 11 is always used in a state where the strap 11 is completely pulled out, such as when used on a truck bed, or other means for fixing the strap 11 is used. When it is outside the storage device (for example, when there is a portion to which the string 11 is tied and fixed near the loading platform), the stopper is not necessarily required.
