Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stopper for passing a string and holding the string at an arbitrary position.

[0002]

2. Description of the Related Art In general, a string is widely used for closing a drawstring or attaching an object. Conventionally, in a string used in this way, a string stopper 10 as illustrated in FIG. 10 and FIG. 11 may be used in order to keep an object closed or tied.

The stopper 10 is formed by forming an elastic material such as a synthetic resin into a cylindrical shape.

[0004] The stopper 10 has a through hole 12 therein.
By passing the string 14 of the book from each end,
It is used in a state where the middle part of the single cord 14 is fixed in a ring shape. In addition, in order to prevent the loop-shaped portion of the string 14 from spreading and loosening, the stopper 10 has an inner diameter of the through hole 12 formed to be slightly smaller than an outer diameter when both ends of the string 14 are bundled in parallel. As a result, both ends of the string 14
2 to prevent the cord 14 from moving in the length direction due to frictional resistance when tightly fitted.

[0005]

When such a string stopper 10 is used, every time the mouth of the drawstring is closed or opened, the intermediate ring-shaped portion of the string 14 is expanded or contracted. However, there has been a problem that the stopper 10 must be slid in a portion bundled in parallel from both ends of the string 14 against large frictional resistance, and the operation is difficult.

[0006] For this reason, hitherto, a stopper for holding a string with a spring has been used. This is in the insertion hole of the stopper,
By passing the parallel bundled part of the string and holding the crimped part of the string with the urging force of the spring installed in this insertion hole, the stopper is prevented from moving in the length direction of this string. I do. At the same time, for example, by pressing a push button attached to the stopper, the stopper is disengaged from the string against the urging force of the spring, and the stopper is slid against the string with a relatively light force. Some of them are moved to make it easier to operate the stopper. However, such a configuration of the stopper using a spring requires the use of components such as a spring and a push button, and has a problem that the number of components increases, the structure becomes complicated, and the cost increases.

The present invention has been made in consideration of the above-described facts, and has as its object to provide a new string stopper which can be easily handled with a light operating force, has a simple structure, and is inexpensive.

[0008]

According to a first aspect of the present invention, there is provided a string stopper, wherein at least one of the body portions has a hollow hole, at least one of the body has an end face with a hollow hole, The body is connected with an elastic material so that the end face is opposed to each other, and by elastically deforming this connection part, the end face of the hollow hole of one body and the end face of the other body are separated from each other. And a connection portion that is opened.

With the above-described structure, the connection portion is elastically deformed, and the holding portion formed by the end face of the hollow hole and the end face portion facing the hollow hole is opened, and the connection portion is passed through the hollow hole. The lace is slidable, and a part of the lace is sandwiched between the end face of one hollow hole, which is a holding portion, and the other end face by the elastic restoring force of the connection part, and the relative movement between the stopper and the string is made. To adjust the size of the loop made in the middle of the string extended from this stopper,
It can be used for opening and closing the mouth of a drawstring or the like, or can be bundled and held.

According to a second aspect of the present invention, there is provided a cord stopper, which is formed in a hollow hole of a tube material while leaving a portion of the tube material as a connection portion at an intermediate position between the tube material and the tube material. And a holding portion formed so as to communicate therewith.

[0011] With the above construction, the respective free ends of the string inserted from the respective free ends into the hollow holes of the tube material are transferred to the outside from the end opening of the intermediate holding portion of the tube material. Since it is configured to be drawn out, it can be manufactured by a simple process of piercing the elastic tube material.

According to a third aspect of the present invention, in the cord stopper according to the second aspect, a strong elastic member which elastically returns with a larger force than other portions of the tube material is provided at a portion corresponding to the connection portion of the tube material. It is characterized by being arranged integrally.

With the above-described structure, the stronger elastic restoring force of the strong elastic member increases the force for pinching the string to the holding portion, and the function of the stopper for stopping the string is improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention is shown in FIGS.
This is shown in FIG. As shown in FIG. 1 and FIG. 2, the stopper 20 according to the first embodiment is attached to a cord 24 that comes through a drawstring 22.

The drawstring 22 is provided with a through hole 26 around the mouth of the bag, a string 24 is passed through the through hole 26, and each end 24 of the string 24 is opened from both ends of the through hole 26.
A and 24B are extended. As shown in FIGS. 1 to 5, the stopper 20 attached to the cord 24 has a hollow portion of the tube, leaving a connection portion 30A at an intermediate portion of the tube formed using an elastic material such as a synthetic resin. The two cylindrical portions 20A and 20B are formed by piercing a notched holding portion 30 so as to communicate with the inside 28.

As shown in FIG. 3, the inner diameter L1 of the hollow hole 28 of the stopper 20 is made slightly larger than the outer diameter of the string 24 so that the string 24 can slide smoothly in the hole 28. Is formed. In addition, the holding portion 30 of the stopper 20
The notch width L2 is formed to be smaller than the outer diameter of the string 24 by a predetermined amount, and the relative movement between the stopper 20 and the string 24 is restrained in a state where the string 24 is sandwiched by the holding portion 30. Is configured.

As shown in FIGS. 4 and 5, the stopper 20 elastically deforms the connecting portion 30A so as to widen the notch portion at the holding portion 30, thereby forming two cylindrical portions 20A,
20B are bent so as to be substantially parallel. When the stopper 20 is folded as shown in FIG.
End portions 24A, 24B of the respective cylindrical portions 20
The string 24 is attached to both ends 24A, 24B of the string 24 by passing through the hollow holes 28 of the strings A, 20B.

Next, the operation and use of the stopper 20 according to the first embodiment configured as described above will be described.

When the drawstring 22 is closed by squeezing the mouth of the drawstring 22 using the string 24, the stopper 20 is first bent as shown in FIGS. 2 and 4, and the relative movement between the stopper 20 and the string 24 is free. And the stopper 20 in this released state
Is slid in a direction away from the free ends of both ends 24A and 24B of the string. Then, by this operation, the stopper 2
The loop formed in the middle of the cord 24 extending from each of the 0 cylindrical portions 20A and 20B shrinks, and the mouth of the drawstring 22 is narrowed and closed. When the hand is released from the stopper 20 in this state, the stopper 20
Due to the elasticity of the connecting portion 30A, the stopper 20 can
A fixed state close to the straight line shown in FIG.

In the fixed state of the stopper 20, the connecting portion 3
With the elastic return force of 0A, both ends 24A, 24B of the string
Are bent at right angles at the notch opening ends of the holding portion 30, respectively, and are sandwiched between these notch opening end surfaces and crimped. At this time, in the fixed state by the holding portion 30, an extremely large resistance force is exerted on the bent portion of the string 24 to move in the length direction of the string 24. The relative movement between the stopper 20 and the string 24 is strongly suppressed. Therefore, the state where the string 24 is closed by squeezing the mouth of the drawstring 22 can be held by the stopper 20.

The drawstring 22 closed as described above.
When the mouth is opened, the stopper 20 in the fixed state, which is extended substantially linearly as shown in FIG. 1, is bent by the holding portion 30 as shown in FIG. The stop 20 in the state is pulled toward both free ends of the string 24, and the loop formed in the middle of the string 24 may be spread.

Further, the stopper 20 constructed as described above is used.
Can be manufactured by cutting a long tube-shaped material made of an elastic material at a predetermined interval, and cutting out the center of the material in the longitudinal direction, leaving a connection portion 30A, so that it is suitable for mass production and provides a low-cost product. Make it possible.

Next, the above-mentioned stopper 20 is, for example, shown in FIG.
May be configured as shown in FIG. That is, this stopper 2
0 has a narrow slit formed in the middle thereof so as to communicate with the hollow hole 28, and a small circular opening 32 including a slit in the diameter direction in a portion of the slit opposite to the connecting portion 30A. , A holding portion 30 is provided.

In the fixing member 20 having the holding portion 30 configured as described above, in the fixed state, both ends 24A and 24B of the string passing through the corresponding holes 28 are respectively bent at substantially right angles by the holding portion 30. The relative movement between the stopper 20 and the string 24 is restrained by bending and pulling out the stopper 20 through the opening 32.

In the stopper 20 shown in FIG. 6, for example,
A tubular elastic material is cut at a predetermined interval, and a cut is made to leave a connection portion 30A at the center in the length direction, and a circular opening 32 is formed at a position diametrically opposite to the connection portion 30A of the tube. The drilling process can be easily performed and manufactured using a general-purpose device.

Next, a description will be given of a case where the stopper 20 is configured as illustrated in FIG. The stopper 20 shown in FIG. 7 is formed by forming a holding portion 30 that opens toward a wide-angle outer surface at a corner portion of an elastic tube material bent at a substantially right angle.

The stopper 20 formed as described above has a ring formed at an intermediate portion of the string 24 extending from the stopper 20, such as when the mouth of the drawstring 22 is squeezed and closed with a string 24. When the diameter is small, even if the entirety of the stopper 20 is bent in accordance with the curvature of the loop of the string 24, since the stopper 20 is bent in advance, the string The force holding the both ends 24A and 24B of the stopper 20 is not weakened, and the fixing state of the stopper 20 can be properly maintained.

The stopper 20 of the first embodiment is
As shown by a two-dot chain line in FIG. 3, a highly rigid wire-like high elastic material 34 is integrally formed on a part of the circumference of an elastic tube material for forming the same, and this strong elastic material 34 is After cutting the integrally formed tube material to a predetermined length, the holding portion 30 can be formed by drilling the strong elastic material 34 at the longitudinal center position of each cut tube material. In the case of such a configuration, the elastic return force of the connecting portion 30A is made stronger, the holding portion 30 makes the holding force of the string 24 stronger, and the stopper 20 can more firmly stop the string 24. And

Further, the stopper 20 can be formed not only as a single unit but also as an integral structure attached to another member. For example, an elastically deformable strip-shaped mounting member is disposed at the mouth of the drawstring 22, and the mounting member is a cylindrical portion 20 which is two elastic tube members.
A and 20B are arranged integrally at a predetermined interval to form the holding portion 30 and are integrally formed. With this configuration, the mounting member can function as a connecting portion that integrally connects the two tubular portions. In this case, the elastic restoring force of the connection portion can be made sufficiently strong, and the stopper 20 is fixed to the drawstring 22 or the like, and the handling thereof can be facilitated.

Further, if a non-slip structure such as an uneven shape is provided near the end of the stopper 20 on the side of the holding portion 30 in the hollow hole 28, the function of the stopper 20 for stopping the cord 24 can be further improved.

The stopper 20 may be configured so that the cylindrical portions 20A and 20B formed as a pair of rigid bodies are integrally connected by a connecting portion 30A made of an elastic material. According to this configuration, the hollow holes 28 of the cylindrical bodies 20A and 20B and the cords 24
Can be made smooth, and the string 24 can be sandwiched between rigid bodies to increase the force for stopping the string 24.

Next, a second embodiment of the string stopper according to the present invention will be described with reference to FIGS. Book second
In the embodiment, the stopper and the string are integrally formed. That is, the one end 24 </ b> A of the cord 24 is fixedly integrated into the hole 28 of the one cylindrical portion 20 </ b> A of the stopper 20. The other end 24 </ b> B of the cord 24 is connected to the other cylindrical portion 20.
B is inserted from the outer end of the hollow hole 28 and is pulled out of the stopper 20 from the end on the side of the holding portion 30.

As described above, in the stopper 20 formed integrally with the string, the other string end 24B passed through the hollow hole 28 of the other cylindrical portion 20B is slid in the released state shown in FIG. Accordingly, the diameter of the loop formed at the intermediate portion of the cord 24 extending from the stopper 20 can be adjusted to be large or small.

After adjusting the loop of the string 24 to the required size in this way, when the hand is released from the stopper 20 in the state shown in FIG. 9, the stopper 30A is returned by the elastic return force of the connecting portion 30A. Reference numeral 20 denotes two cylindrical portions 20A and 20B as shown in FIG.
Are in a substantially linear state. In this fixed state,
The other end 24 </ b> B of the string 24 is clamped by the clamping section 30, and the relative movement between the stopper 20 and the string end 24 </ b> B is suppressed.

When the size of the loop formed by the string 24 is to be adjusted again, the connecting portion 30A is bent so that the stopper 20 is changed from the fixed state shown in FIG. 8 to the released state shown in FIG. Adjustment is performed in the release state of 9.

As described above, when the cord 24 and the stopper 20 are integrally formed, there is no need to worry about losing one of them as compared with the case where they are separate bodies, and the handling thereof can be facilitated. Further, the fastener 20 integrated with the cord 24 can be variously used as a tool or the like for bundling cords of electric appliances.

The structure, operation, and effects of the string stopper of the second embodiment other than those described above are the same as those of the above-described first embodiment, and therefore description thereof will be omitted.

[0038]

According to the string stopper according to the first aspect of the present invention, at least one of the two body portions provided with the hollow holes is
An end face of at least one hollow hole and the other end face are separated from each other so that they are connected in series with a connecting portion made of an elastic material, and this connecting portion is elastically deformed to form an end face of the hollow hole. In a state where the holding portion constituted by the and the end face portion facing this is opened, the string passed through this hollow hole is made slidable,
The elastic restoring force of the connecting portion clamps a part of the string between the end surface of one hollow hole, which is the clamping portion, and the other end surface, thereby restraining the relative movement between the stopper and the string. The size of the loop formed by the middle part of the string extended from the tool is adjusted and held, and it can be used for opening and closing the mouth of a drawstring or the like, or can be bundled and held. Since the stopper having such a configuration has a simple structure and can be easily manufactured,
Inexpensive products can be provided. In addition, if the connecting member is elastically deformed with a small operating force and the holding portion is opened, the string can be smoothly slid with respect to the stopper, so that there is an effect that the operation in use can be facilitated.

According to the string stopper of the second aspect, the tube is made of an elastic material, and communicates with the inside of the hollow of the tube while leaving a part of the tube as a connection part in the middle. In the hollow hole of this tube material, each corresponding free end of the string inserted from each free end is drawn out from the end opening of the intermediate holding portion portion of the tube material. Since it is configured, it can be manufactured by a simple process of piercing the elastic tube material, so that there is an effect that it is suitable for mass production and a low-cost product can be provided.

Further, the invention according to claim 3 is based on claim 2
In the stopper of the string, a strong elastic member that elastically returns with a larger force than other parts is integrally arranged at a portion corresponding to the connection portion of the tube material, so that the string is sandwiched between the holding portions. There is an effect that the attaching force can be made stronger and the function of the stopper to restrain the string can be improved.
