An outward locking protrusion 33 is formed at each end of the large diameter portion 32 .

The assembly and use of each part having each of the above-described shapes will be explained below, following the process of winding up and storing the filament A of cords.

First, as shown in FIG. 2, the approximately central part of the filament A of the cord is folded in half, and then rolled up and placed in the hook groove 8 of the approximately disc-shaped plate material 3 at the center of the body 1. As shown in the figure, hook it up and rotate the winding storage main body 1 in the direction of the arrow.
Wind up the striatum to an appropriate size.

This state is shown in Figure 3, where B is the telephone and C is the telephone.
is a terminal fixture mounted on the wall.

Next, as shown in FIG. 4, the winding storage main body 1 is fitted into the bowl-shaped base 5, and the hook portion of the hook portion 17 of the shaft end portion of the substantially disk-shaped plate material 4 in the lower position is inserted. 1B is hooked and locked to the hook bending portion of the coil spring 6, and then the winding storage main body 1 is further turned to wind up the filament body A sufficiently.

Finally, the bowl-shaped lid body 7 is placed over the bowl-shaped base body 5, and the lid fixing edges 23 and 24 of the cylindrical peripheral frame portion 20 of the bowl-shaped base body 5 are attached to the bowl-shaped lid body 7.
When the bowl-shaped lid body 7 is turned so as to fit into the inverted-shaped lid retaining circumferential grooves 30.30, the bowl-shaped base 5 is inserted into the engaging portion of the inverted-shaped lid retaining volume 130.30. The lid retaining edges 23 and 24 of the lids are inserted into each other and are prevented from being removed from each other, and the fifth
The state shown in the figure is reached, and the winding container S is assembled.

In FIG. 5, the opposing openings 21.28 of the bowl-shaped base body 5 and the bowl-shaped lid body 7, respectively, for drawing out the filament body are in a state of alignment, and from the openings 21.28, the lines in the upper part in the figure are aligned. With a part of the striatum A exposed, a part of the striatum A is exposed from the striatum drawer opening (not shown) on the lower side of the bowl-shaped base 5 in the figure. is exposed, and most of the central portion of the filament A is wound up and stored.

If the length of the striatum A protruding from the winding storage container S is
If it is too short, pull the filament insert with both hands in the direction of the arrow in FIG. The filament body A, which has been wound around the winding storage main body 1, is pulled out against the spring force of the winding spring 6.

When pulling out this filamentous body A against the winding spring 6, the shape of the winding storage main body L when the filament body A is released from both hands varies depending on the strength of the tensile force applied with both hands or the length of the tensile dimension. The locking state of the locking cam body 29 on the side of the bowl-shaped lid body 7 and the locking member 11 on the winding storage main body 1 side at the time of reversal or the state of rotational sliding contact, respectively, is No. 9 according to FIGS. 7 and 8. This will be explained below.

First, FIG. 7 shows that when the tensile force applied with both hands is weak when pulling out the filament A against the coiled spring 6,
Or, if the tensile dimension is short, and when the filament A is pulled out, the locking member 11 on the winding storage main body 1 side is at the position indicated by the chain line in the figure, and in this state, the filament A is pulled out. When released from both hands, the winding storage main body 1 is reversed by the spring force of the coil spring 6, and the locking member 11 engages with the large diameter portion 32 of the locking cam body 29.
It moves in the direction of the arrow to the position indicated by the solid line in the figure while sliding in contact with the outer circumferential arc.

Due to the sliding contact, the reversal speed (strength) of the winding storage main body 1 is
is decelerated, and the wedge-shaped locking portion 9 of the locking member 11
Since the tip of the elastic tail portion 10 is positioned slightly outward from the axial direction, it abuts against the locking protrusion 33 of the locking cam body 29, and the end portion of the elastic tail portion 10 is pressed by the presser protrusion 14.
It bends as shown in the picture. The elastic tail 10 corresponds to this bent portion.
A force acts to return to its original state, and a force acts to cause the tip of the locking portion 9 to push back the locking protrusion 33 of the locking cam body 29 in the opposite direction to the reversal direction. At this point, the brake is applied, and the winding storage main body 1 stops in the locked state shown by the solid line in the figure.

This makes it possible to pull out the filamentous body A by an appropriate amount and lock it at that point.

Next, FIG. 8 shows that when the tensile force applied with both hands is strong when pulling out the filament A against the coiled spring 6,
Or, if the tensile dimension is long, and when the filament A is pulled out, the locking member 11 on the winding storage main body 1 is at the position indicated by the chain line in the figure, and in this state, the filament A is held with both hands. When released, the winding storage main body 1 is reversed by the spring force of the coiled spring 6, and at first (the chain line portion), the tip of the locking portion 9 of the locking member 11 and the small diameter portion 31 of the locking cam body 29 are Since the outer circumferential arcs of the locking member 11 are separated from each other, the reversal speed of the winding storage main body l is accelerated by the spring force of the coil spring 6, and the outer circumferential arc of the large diameter portion 32 of the locking cam body 29 and the locking member 11 are engaged with each other. The brake is not applied even by the temporary sliding contact with the tip of the locking part 9, and finally, as shown by the solid line in the figure, the tip of the locking part 9 of the locking part No. 11 material 11 comes into contact with the locking cam. It overcomes the bending repulsive force of the elastic tail 10 and climbs over the locking protrusion 33 of the body 29.

Therefore, in order to wind up a large amount of the filament A, if you pull it strongly and then release it, or if you pull it for a certain length and release it, the winding storage main body 1 will rotate by the spring force of the coil spring 6 without stopping midway. The striatum A will be rolled up.

In this embodiment, the approximately disk-shaped plates 2, 3.4 are formed into perfect circles as shown in the drawings, but they may be polygonal as long as they are large enough to be accommodated within the bowl-shaped base 5.

In addition, the lid fixing edges 23 and 24 protruding outward from the cylindrical peripheral frame portion 20 of the bowl-shaped base body 5 are made to have different sizes, and the corresponding lids on the inner circumferential surface of the bowl-shaped lid body 7 are made to have different sizes. Peripheral groove for stop 30.30
If the sizes are made to be different and the sizes are formed so that they can be easily seen from the outside, when the bowl-shaped lid body 7 is placed on the bowl-shaped base body 5, the positioning can be easily performed and the combination becomes easy. be.

As described above, the present invention includes a winding storage body formed by axially forming three substantially disc-shaped plates, a bowl-shaped base body housing a coiled spring inside, and a locking cam body fixed at the center of the interior. A hooking groove for hooking the central part of the filament body is provided in the approximately disc-shaped plate material located at the center of the winding storage main body, and the approximately disc-shaped board material located at one outer position is provided with a hook groove for hooking the center portion of the filament body. A locking member is disposed on the locking cam body in the bowl-shaped lid body, and the locking member locks or rotates in sliding contact depending on the strength of the tensile force applied to the filament body or the length of the tensile dimension, and the locking member is disposed in the locking cam body in the bowl-shaped lid body, and A hook portion for hooking onto a coiled spring housed in the bowl-shaped base is provided at the shaft end portion of the disc-shaped plate material, and at least one opening for drawing out the filament body is formed in the bowl-shaped base. , and the bowl-shaped lid body is also formed with an opening for drawing out the filamentous body, and in a state where the filament body is wound around the winding storage body, the winding storage body is connected to the bowl-shaped base body and the bowl-shaped body. Since it is arranged with the axis aligned inside the lid body, the filamentous body of the cord can be easily pulled out and retracted, and the filamentous body of the cord does not come into contact with any part of the body. It does not cause any damage and is compactly formed, so it does not get in the way indoors, and
Not only is it convenient to carry, it can be easily locked at a desired length and can be automatically reeled in to the end when pulled strongly or slightly longer and released.
