Hereinafter, an embodiment in which the winding device of the present invention is embodied with respect to a winding device for winding a shoelace of an athletic shoe will be described.
FIG. 3 shows a shoe S equipped with a shoelace winding device 1 according to an embodiment of the present invention at a position corresponding to the outer upper surface of the instep, and the shoe S is made of a resin-coated metal wire. The upper part of the shoe S can be tightened by the shoelace 2.

As shown in FIGS. 1 to 10, the shoelace winding device 1 includes a base member 3, a reel 4 for winding the shoelace 2, and a stopper member 5 for controlling the rotation and stop of the reel. A dial 6 for rotationally driving the reel 4, and a shaft member 7 rotatably fixed to the base member 3 for mounting the dial 6 and the stopper member 5 to the base member 3. The spring member 8 is supported at one end by the shaft member 7.
As shown in FIG. 11, the stopper member 5 is attached to the lower side of the dial 6 and is integrated with the dial 6 to constitute a lower surface portion of the dial 6.

  The base member 3 is integrally formed by forming a thin plate-like flange 31 so as to protrude around the bottom of a bottomed cylindrical reel storage portion 32 for rotatably storing the reel 4. The shoelace winding device 1 can be fixed to the shoe S by the flange 31 being sewn and fixed to the shoe S.

The reel housing portion 32 is provided with a rotating shaft 33 for pivotally supporting the reel 4 at the center of the bottom thereof, and a gear 34 is formed annularly along the inner peripheral surface of the reel housing portion 32. Has been.
The gear 34 forms a ratchet mechanism in cooperation with four elongated plate-like claws 51 formed on the stopper member 5, and the claws 51 can move only in the direction in which the shoelace 2 is wound (forward rotation). Thus, the cross section is formed in a “sawtooth” shape.

  Further, the base member 3 is formed with two shoelace pulling openings 35 that open to the inner bottom portion of the reel storage portion 32, and the shoelace 2 wound around the reel 4 is moved from the reel storage portion 32 to the outside. It can be pulled out.

  The reel 4 includes a shoelace winding drum 41 for winding the shoelace 2, a rotating shaft portion 42 disposed inside the shoelace winding drum 41, and an inner periphery of the shoelace winding drum 41. And an annular groove 43 formed by the shoelace winding drum 41, the rotary shaft portion 42, and the annular portion 43. The annular portion 43 connects the surface and the outer peripheral surface of the rotational shaft portion 42. Yes.

The rotation shaft 33 of the base member 3 is inserted on the inner surface side of the rotation shaft portion 42 so that the reel 4 can rotate in the reel storage portion 32.
The groove portion 44 of the reel 4 is arranged on the side (lower side) facing the bottom portion of the base member 3, and the shoelace 2 introduced into the groove portion 44 from the outer peripheral surface side of the shoelace winding drum 41. Two engaging projections 45 are provided in the groove 44 for sandwiching the tip portion and holding it in the groove 44.

On the upper side of the reel 4, a plurality of upward fins 46 are formed along the inner peripheral surface of the shoelace winding drum 41, and below the stopper member 5 constituting the lower surface portion of the dial 6. The rotation of the dial 6 can be transmitted to the reel 4 by meshing with the formed downward fin 52.
In the shoelace winding device 1 of the present invention, as shown in FIGS. 1D and 1E, the inclination angle θ of the engaging surface f of the downward fin 52 and the upward fin 46 that are engaged with each other is 89 degrees to By being within the range of 80 degrees, that is, the engaging surfaces f of the downward fins 52 and the upward fins 46 that are engaged with each other are formed in an oblique shape that meshes so as not to be disengaged in the vertical direction. Even if the height of the engaging surface f of the downward fin 52 and the upward fin 46 is lowered, a stable meshing state can be obtained, and the meshing can be released smoothly.

In the shoelace winding device 1 of the present invention, the play length t1 when the downward fin 52 and the upward fin 46 are engaged with each other is determined by the engagement surface f of the downward fin 52 and the upward fin 46 that engage with each other. By making the tip portion larger than the length t2 projecting from the base end portion, the downward fin 52 and the upward fin 46 can be smoothly engaged, and the engagement can be released smoothly. it can.
As an example, when the heights of the fins 46 and 52 are 1.55 mm and the play length t1 is 0.29 mm, the length is as long as the inclination angle θ is within a range of 89 degrees to 80 degrees. t2 is 0.027 to 0.273 mm, and does not exceed the play length t1.
However, when the inclination angle θ is 79 degrees, the length t2 becomes 0.301 mm, which exceeds the play length t1, and there is a possibility that the smooth engagement between the fins 46 and 52 may be hindered.

The stopper member 5 is fitted to the inner side (lower side) of the dial 6 by engaging mounting claws 53 projecting at the four corners thereof with engaging holes 61 formed through the dial 6. It is integrated with the dial 6 and is interposed between the reel 4 and the dial 6 so that the rotation of the dial 6 can be transmitted to the reel 4 and from the dial 6 so that the reel 4 can freely rotate. A release state in which the reel 4 is separated can be realized.
The four claws 51 formed on the stopper member 5 are in the form of an elongated plate and are spaced apart from each other by 90 degrees, and the outer surface of the distal end portion and a position slightly closer to the proximal end portion from the distal end portion. A protrusion 51a formed on the inner surface of the reel housing 32 is engaged with a gear 34 formed on the inner peripheral surface.

Further, as shown in FIG. 11, a wall portion 66 with which the base abuts from the central portion of the outer surface of the claw 51 is provided with the dial 6 so as to prevent the outer surface of the base portion from bending outward from the central portion of the claw 51. 4 are formed to protrude from the lower surface. Thereby, even if the dial 6 is urged in the direction of loosening the shoelace 2 and the tip portion and the protrusion 51a of the claw 51 strongly contact the gear 34, the claw 51 is not bent outward, and the shoelace 2 Can be kept locked.
Further, a recess 56 capable of burying the vicinity of the head of the shaft member 7 (the vicinity of a flange 72 described later) is formed on the upper surface of the periphery of the shaft hole 54 formed in the central portion of the stopper member 5. Thus, the thickness of the dial 6 can be reduced.

  The shaft member 7 is fixed to the base member 3 with a screw 9 so as to rotatably mount the integrated dial 6 and stopper member 5 to the base member 3. It is possible to hold and guide the dial 6 and the stopper member 5 in a movable state between a lock position where the dial 6 and the stopper member 5 are close to the base member 3 and a release position which is separated from the base member 3. ing.

  The shaft member 7 is formed in a quadrangular prism shape, and a bearing portion 71 formed by cutting out two opposite side portions in the vicinity of the upper end portion of the shaft member 7 in a direction orthogonal to the axial direction. On the other hand, when the linear one end part (shaft part 81) formed in the spring member 8 is inserted, the spring member 8 is pivotally supported.

Furthermore, since the shaft member 7 has a quadrangular prism shape, the strength of the bearing portion 71 can be increased and the shaft member 7 can be miniaturized.
Further, as shown in FIG. 9 (E), the bearing portion 71 of the shaft member 7 communicates with a screw insertion hole 73 that is provided near the center of the shaft portion 7 along the axis of the shaft member 7, The shaft member 7 is downsized.

The spring member 8 is curved and formed in a substantially U shape as a whole, and the spring portion 82 on the other end side of the curve is always attached to the locking portion 62 provided on the inner surface of the integrated dial 6 and stopper member 5. It comes to contact.
The locking portion 62 with which the other end portion (spring portion 82) of the spring member 8 abuts is provided at the narrowest outer end portion of the spring housing space 63 formed in a wedge shape at the boundary portion between the dial 6 and the stopper member 5. It has been.

The integrated dial 6 and stopper member 5 are moved in the vertical direction from the lock position to the release position, so that the reel 4 can be switched from the locked state to the released state.
Furthermore, it is set so that a reversal position where the spring portion 82 of the spring member 8 is most compressed to the shaft member 7 side exists between the lock position and the release position.

A disc-shaped cover member 10 is fitted on the upper side of the dial 6 so as to be in close contact with each other so as to reduce the thickness of the shoelace winding device 1 and dust or the like enters the shoelace winding device 1. There is no such thing.
A through hole 11 is formed in the central portion of the cover member 10, and the screw 9 inside (the lower side) of the cover member 10 is operated through the through hole 11 so that the base member 3, the reel 4, and the dial. 6. The shaft member 7 can be removed.
Further, an annular groove 12 is formed around the through hole 11 on the lower surface of the cover member 10, and the thickness of the cover member 10 is increased by entering the upper end portion of the shaft member 7 therein. There is no such thing.

  As a wire-like shoelace 2 made of a resin and metal composite material used together with the shoelace winding device 1, a wire rope in which 49 stainless steel wires having a diameter of 0.11 to 0.13 mm are twisted together. What processed with the swaging machine and coat | covered with the nylon resin can be used suitably.

Next, a method for assembling and manufacturing the components of the shoelace winding device 1 described above will be described.
First, in order to mount the reel 4 on the base member 3 of the shoelace winding device 1, the tips of the shoelace 2 are inserted into the shoelace pulling outlets 35 at two locations, respectively, and the shoelace 2 of the shoelace 2 is inserted from the reel storage portion 32 side. Pull out both ends.
Then, the ends of the shoelace 2 are sequentially inserted into the wire insertion holes 47 provided in six places on the reel 4 so as to sew the tip of the shoelace 2, thereby fixing both ends of the shoelace 2 to the reel 4. To place.

  Next, the stopper member 5 is fitted to the inner side (lower side) of the dial 6 so that the stopper member 5 is integrated with the dial 6, and the shaft member 7 and the spring member 8 are assembled to them.

In this case, the spring member 8 is inserted into the substantially square shaft hole 64 formed in the dial 6 and the substantially square shaft hole 54 formed in the stopper member 5. The spring portion 82 of the spring member 8 is inserted into the spring accommodating space from the expanded portion 64a in which the shaft hole 64 of the dial 6 is expanded, and the spring portion 82 is narrowest from the inner end side of the spring accommodating space 63 to the outer end narrowest. It is guided so as to turn to the part side and is assembled to the dial 6.
Since the flange 72 formed on the upper end portion of the shaft member 7 contacts the locking step portion 65 formed on the edge of the shaft hole 64 of the dial 6, the dial 6 does not come off the shaft member 7.

  The spring portion 82 of the spring member 8 is guided so as to rotate from the inner end side of the spring accommodating space 63 toward the outer end narrowest portion side, on the edge of the shaft hole 54 of the stopper member 5 (on the dial side). This is because the inclined surface 55 facing the) is formed.

After the stopper member 5, dial 6, shaft member 7 and spring member 8 are assembled according to the above procedure, the screw 9 is inserted through the screw insertion hole 73 formed along the axis of the shaft member 7, and the shaft member 7, etc. Is attached to the base member 3.
At this time, the length of the shaft member 7 in the axial direction is formed by forming the enlarged diameter portion 73 a of the screw insertion hole 73 so that the head of the screw 9 is inserted to a position below the bearing portion 71. And the thickness of the shoelace winding device 1 is reduced. That is, the shoelace winding device 1 can be made thin and compact.

Finally, the shoelace winding device 1 can be assembled by fitting the cover member 10 into the upper surface of the dial 6.
When disassembling the shoelace winding device 1 for maintenance or repair, a screwdriver is inserted from the through-hole 11 of the cover member 10 and the screw 9 is removed, so that the assembled stopper member 5, dial 6, The shaft member 7 and the spring member 8 can be removed from the base member 3.

In addition, as materials constituting each member in the shoelace winding device 1 of the present embodiment, the following materials are used as an example in consideration of strength, durability, elasticity, and the like, but are limited to these materials. It is not something.
Base member 3 ... nylon reel 4, stopper member 5, shaft member 7 ... POM (polyacetal)
Dial 6 ... Nylon and TPE (thermoplastic elastomer) around it
Spring member 8 ... Stainless steel Screw 9 ... Carbon steel Cover member 10 ... ABS resin

A method of using the shoelace winding device 1 configured as described above will be described.
In order to tighten the shoelace 2 after wearing the shoe S, the lock position where the dial 6 of the shoelace winding device 1 is brought close to the base member 3, that is, the upward fin 46 and the downward fin 52 are engaged. The dial 6 is rotated in a state where the shoelace 2 is wound, and the shoelace 2 is wound around the reel 4.
In this case, the reel 4 does not rotate in the direction in which the shoelace 2 is loosened by the tips and protrusions 51a of the claw 51 of the stopper member 5 coming into contact with the gear 34.

Further, since the reversal position where the spring member 8 is most compressed is set at a position between the lock position and the release position, the spring member 8 is shown in FIG. 1A when the dial 6 is in the lock position. The dial 6 is held in the locked position.
At this time, the spring member 8 faces the direction of lifting the shaft member 7 and pressing the dial 6 downward.

  Next, in order to loosen the tightening of the shoelace 2, it is necessary to release the engagement state between the upward fin 46 and the downward fin 52, and the dial 6 of the shoelace winding device 1 is pulled upward.

At this time, the spring member 8 is compressed, and by pulling the dial 6 further upward against the repulsive force, the spring member 8 exceeds the reversal position where the spring member 8 is compressed most, and between the lock position and the release position. Thus, when the direction in which the spring member 8 is compressed is switched, the dial 6 is moved to the release position away from the base member 3 (state shown in FIG. 1B).
The other end portion (spring portion 82) of the spring member 8 is always in contact with a locking portion 62 provided on the inner surface of the dial 6, and wear of parts can be prevented.

Thus, since the spring member 8 is clearly switched between the lock position and the release position, not only is the operability excellent, but it is also easy to grasp the state of the dial 6 position.
When the dial 6 moves from the lock position to the release position as described above, the meshing between the upward fins 46 of the reel 4 and the downward fins 52 of the stopper member 5 is smoothly released, and the reel 4 can freely rotate. The shoelace 2 is loosened.

  On the other hand, when the dial 6 is pressed downward so as to move from the release position to the lock position, the spring member 8 goes over the reverse position where the spring member 8 is compressed most, and the upward fin 46 and the stopper member 5 of the reel 4 are reversed. Therefore, the shoelace 2 can be wound around the reel 4 and the shoelace 2 can be tightened.

  In the present specification, the “dial” is not particularly limited as long as it functions as an operation unit for rotationally driving the reel 4, and may be polygonal. .
