Description

The present invention relates to a cord stopper through which a string body can be inserted and fixed at an arbitrary position of the string body.

Conventionally, there is a cord stopper that is attached to an arbitrary position of the string body and that adjusts the extension length of the string body to elastically hold it at a predetermined length. Such a cord stopper includes a case member of a tubular body through which a string body is inserted in one direction, and a piston member inserted and assembled inside the case member.

For example, in the cord fastener which is the cord stopper disclosed in Patent Document 1, the piston portion is locked to one end of the tubular body of the case member, and the case member is inserted from the locking portion. It consists of a spring part that protrudes in the direction and expands and contracts in the insertion direction, and a head provided at the tip of the spring part. Is provided. The case member has a tubular body formed by a pair of side surface portions provided on both left and right edges of the upper surface portion and the lower surface portion, and the upper surface portion and the lower surface portion, and a piston is inserted into one end of the tubular body. An insertion port in which the stop portion is locked, and the other end portion is an outlet in which the head is elastically pressed to hold the string body and the held string body is pulled out. Further, an opening is formed in which the operating convex portion of the piston member slidably projects outward.

To use this cord fastener, insert both ends of the folded string into the insertion slot from the outlet of the case member, and insert the piston into the insertion slot of the case member between the pair of strings. Insert the piston and assemble. As a result, the holding protrusion on the head of the piston is urged by the string body to bite into it and hold the string body, and the folded annular part of the string body extends outward from the outlet of the case member. do. When changing the length of the annular part of the string body, operate the operation convex part provided on the head of the piston to move the head away from the outlet against the urging force of the spring part. .. As a result, the holding of the string body is released, the string body becomes slidable, and the length of the annular portion of the string body can be changed.

However, the cord fastener disclosed in Patent Document 1 is provided with an operation convex portion on the head of the piston, and the operability of assembling the string body and adjusting the length is not good. Therefore, as another cord stopper, there is one in which a pair of leg portions are provided on the side of the locking portion of the piston portion and the spring portion. This is a connecting member in which a pair of legs are provided along the insertion direction of the case member, one end of the leg is continuous with the head, and the other end is located apart from the outside of the locking portion. It is continuous and has a ring shape. Such a cord stopper is easy to assemble to the case member, and has good operability for holding and releasing the string.

In the latter case of the above background technique, when the piston portion is provided with the leg portion and the connecting member, when assembling the piston portion to the case member, the head portion of the piston portion is inserted first from the insertion port of the case member and connected. The member is pushed and inserted, and the locking portion is locked to the locked portion at a predetermined insertion depth position of the case member. However, since the connecting member to be pushed in and the locking portion are separated from each other and the locking portion is connected to the head via the spring portion, the deformation of the spring portion is caused by the pushing amount even if the locking portion is pushed in. It is difficult to securely lock the locking portion to the locked portion of the case body. Therefore, in order to lock the locked portion and the locked portion, the connecting member must be pushed with a strong force, which is difficult to work with and often results in an incomplete locking state. , The work efficiency is not good. Further, if the end portion of the locking portion can be directly pressed to be locked to the locked portion, reliable locking is possible, but the space between the locking portion and the connecting member is narrow, and the locking portion is Could not be pressed.

The present invention has been made in view of the above-mentioned problems of the background technique, and an object of the present invention is to provide a cord stopper which can be reliably assembled with a simple structure and has good assembly work efficiency.

The piston member 12 is provided with a pair of leg portions 16 to be inserted into the case member 14, and the pair of leg portions 16 are columnar columns extending linearly in parallel with each other. In the following description, the direction in which the pair of legs 16 of the piston member 12 protrudes is the front-rear direction, which coincides with the insertion direction of the string body 62. The direction in which the pair of legs 16 face each other is called the left-right direction, and the direction orthogonal to the front-back direction and the left-right direction is called the front-back direction or the thickness direction. The cross-sectional shape of the leg 16 intersecting the longitudinal direction, that is, the front-back direction is a rectangle, which is short in the left-right direction and long in the front-back direction. The thickness in the front and back directions is not constant, and one end 16a side is slightly wider.

The piston member 12 is provided with one head portion 18 for connecting the end portions 16b having a shorter thickness in the front-back direction in the longitudinal direction of the pair of leg portions 16. The head 18 is a substantially isosceles triangle symmetrical about a virtual line along the front-rear direction, and the ends 16b of the legs 16 are continuous with both ends of the base of the isosceles triangle. The thickness of the head 18 in the front-back direction is substantially constant, and guide protrusions 20 are provided on the front surface and the back surface of the head 18 on a virtual line passing through the center. The guide protrusion 20 projects outward from the surface of the head 18 in the front-back direction, and the surface of the leg portion 16 on the opposite end 16a side is formed by a plane substantially parallel to the front-back direction and the left-right direction. Holding protrusions 22 are provided on the left and right hypotenuses of the head 18. The holding protrusion 22 has a triangular shape when viewed from the front and back, and protrudes in a direction away from the apex angle which is the tip of the head 18. A total of eight holding projections 22, four on the left and right sides of the head 18, are continuous and project in a direction substantially parallel to each other. The tip portion of the holding protrusion 22 is slightly rounded and has a constant shape in the front and back directions.

The ends 16b of the pair of legs 16 are slightly curved so that the portions continuous with the head 18 are close to each other. Further, the width in the left-right direction is thinner from the portion where the curve starts to the head 18 than the other portions, and is easily elastically deformed.

The pair of legs 16 gradually widen toward both sides in the front-back direction as they approach the ends 16a on the opposite side of the head 18, and the ends 16a are formed to be the widest. One connecting member 24 is continuously provided on the widest end portion 16a, and the end portions 16a are connected to each other via the connecting member 24. The connecting member 24 is a rod-shaped member that is long in the left-right direction. The pair of legs 16, the head 18, and the connecting member 24 are annular. The connecting member 24 is formed to be thinner in the front-back direction than the widest end of the leg portion 16, and is provided closer to one end of the widest end portion 16a of the leg portion 16 in the front-back direction. Has been done. At the other end edge portion of the end portion 16a of the leg portion 16 in the front-back direction, a space 26 having a shape in which the connecting member 24 is recessed in the front-back direction is formed. The notch of the connecting member 24 forming the space 26 is a part of the shape in which the connecting member 24 is projected onto a surface intersecting the insertion direction of the string body 62, specifically, a surface parallel to the front and back directions and the left-right direction. It should be missing. The thickness of the connecting member 24 in the front-back direction is formed to be less than half the thickness of the end portion 16a of the leg portion 16, and the space 26 is opened with a width slightly wider than the thickness of the connecting member 24 in the front-back direction. , It is released in the front-back direction and the front-back direction. This is large enough for a worker's finger to enter and directly push the locking portion 30.

A spring portion 28 is provided between the pair of leg portions 16. The spring portion 28 is provided at the bottom of the head portion 18 and reaches the vicinity of the extending connecting member 24 along the leg portion 16. The spring portion 28 is a plate-like body having a certain thickness in the front and back directions and a narrow width in the left-right direction, and has elasticity by being curved and bent at three points in the longitudinal direction, and is particularly elastically deformed in the front-rear direction. Cheap.

A plate-shaped locking portion 30 long in the left-right direction is provided at an end portion of the spring portion 28 located near the connecting member 24 on the opposite side of the head portion 18. The locking portion 30 has a cubic shape that is long in the left-right direction, the thickness in the front-back direction is substantially the same as that in the spring portion 28, and the width in the left-right direction is wider than that of the spring portion 28 and shorter than that of the connecting member 24. The locking portion 30 is substantially parallel to the connecting member 24, is located slightly closer to the head 18 than the connecting member 24, and is separated from the connecting member 24. Therefore, the spring portion 28 and the locking portion 30 are located inside the ring formed by the pair of leg portions 16, the head portion 18, and the connecting member 24.

A spring portion 28 is continuous at the center in the left-right direction on the surface of the locking portion 30 on the head 18 side, that is, the surface on the side opposite to the connecting member 24, and the spring portion 28 is sandwiched between the spring portions 28 in the left-right direction. Both side portions slightly project toward the head 18 side. On both side portions of the locking portion 30 in the left-right direction sandwiching the spring portion 28, two locking claws 32 protruding in the front and back directions are provided on one side of each of the front and back surfaces, for a total of four. The surface of the locking claw 32 on the side of the connecting member 24 is formed of a plane substantially parallel to the front-back direction and the left-right direction.

The case member 14 is also integrally molded with a synthetic resin such as polyacetal, polyamide, polypropylene or the like. The case member 14 has a hollow fitting portion 40 into which the piston member 12 is inserted. The fitting portion 40 is surrounded by a pair of side surface portions 46 located on the left-right side edges of the upper surface portion 42 and the lower surface portion 44 and facing each other at a predetermined distance between the upper surface portion 42 and the lower surface portion 44. It is provided in a tubular body. As shown in FIG. 4, the fitting portion 40 is a space in which the piston member 12 is fitted with a margin, and a gap in which a string body 62, which will be described later, is sandwiched between the piston member 12 and the side surface portion 46. have.

One opening of the tubular body of the case member 14 is an insertion port 48 into which the piston member 12 is inserted, and the opening on the opposite side is pressed against the head 18 of the piston member 12 to hold the string body 62. The outlet 50 from which the held string body 62 is pulled out. The outlet 50 is formed smaller than the insertion port 48.

The side edge portions 46a of the pair of side surface portions 46 forming the outlet 50 project outward from the side edge portions 42a and the side edge portions 44a of the upper surface portion 42 and the lower surface portion 44, and the side edge portions of the pair of side surface portions 46. One mounting portion 52 is continuously provided on the 46a, and the side edge portions 46a are connected to each other via the mounting portion 52. The mounting portion 52 is a rod-shaped member that is long in the left-right direction. The mounting portion 52 is formed to have a thickness in the front and back directions thinner than the side edge portion 46a of the side surface portion 46, and is provided near the end of the side edge portion 46a continuous with the side edge portion 44a of the lower surface portion 44. .. The other end of the side edge portion 46a of the side surface portion 46 in the front-back direction is a space communicating with the outlet 50. The thickness of the mounting portion 52 in the front-back direction is formed to be less than half the thickness of the side edge portion 46a of the side surface portion 46, and the space in the front-back direction is wider than the thickness of the mounting portion 52 in the front-back direction. It's a little wide. This is large enough for the string body 62 pulled out from the outlet 50 to pass through.

The side edge portion 44a of the lower surface portion 44 is provided with a guide groove portion 54 notched in a rectangular shape. The guide groove portion 54 is a rectangle long in the front-rear direction. The side edge portion 42a of the upper surface portion 42 is provided with a guide recess 58 at a position facing the guide groove portion 54. The guide recess 58 is provided by cutting out a part of the thickness of the upper surface portion 42 from the surface on the fitting portion 40 side, has the same shape as the guide groove portion 54, and is a rectangular shape long in the front-rear direction.

A locking claw fixing portion 56, which is a locked fixing portion to which the locking claw 32 of the piston member 12 is locked, is provided at a position close to the insertion port 48 of the upper surface portion 42 and the lower surface portion 44. The locking claw fixing portion 56 is a rectangular through hole into which the locking claw 32 is inserted and locked, and is formed so as to penetrate the upper surface portion 42 or the lower surface portion 44. Two locking claw fixing portions 56 are provided on the upper surface portion 42 and two on the lower surface portion 44, for a total of four.

Next, the locking operation of the cord stopper 10 of this embodiment will be described below. First, this cord stopper 10 is used by being attached in the vicinity of an opening such as a bag (not shown). A string body 62 is inserted into the opening along the peripheral edge portion, and both end portions 62a of the string body 62 are pulled out from a hole for the string or the like. The opening is opened and closed by changing the length of pulling out both end portions 62a of the string body 62.

As a method of attaching the cord stopper 10, first, as shown in FIGS. 3 to 5, before assembling the piston member 12, the tape member 60 is wound around the attachment portion 52 of the case member 14, and the end portion of the tape member 60 is attached. Fix it in the vicinity of the hole for the string in the opening of the bag or the like. Both end portions 62a of the string body 62 pulled out from the hole for the string or the like are inserted into the fitting portion 40 from the outlet 50 and pulled out from the insertion port 48 to the outside. Both end portions 62a of the pair of string bodies 62 are brought close to the left and right ends of the insertion port 48, and the piston member 12 is placed between the pair of string bodies 62 at the center of the insertion port 48 with its head 18 first. And plug it in. A locking portion 30 continuous with the spring portion 28 is exposed in the space 26 adjacent to the connecting member 24 of the piston member 12, and a finger is inserted into the space 26 to push the locking portion 30 into the back of the piston member 12. The locking claw 32 of the locking portion 30 is inserted into the locking claw fixing portion 56 of the case member 14 and locked.

The distance between the tips of the locking claws 32 located in the front and back directions of the piston member 12 is larger than the distance between the inner side surfaces of the upper surface portion 42 and the lower surface portion 44 of the case member 14, that is, the distance between the front and back surfaces of the fitting portion 40. Slightly long. Therefore, when the piston member 12 is inserted into the fitting portion 40, the case member 14 is pushed by the locking claws 32 and spreads in the front and back directions. When the locking claw 32 coincides with the locking claw fixing portion 56, the locking claw 32 is inserted into the locking claw fixing portion 56, the elastic deformation of the case member 14 is restored, and the locking claw 32 is fixed to the locking claw. I can't get out of the part 56. Since the surface of the locking claw 32 on the connecting member 24 side is formed as a plane perpendicular to the front-back direction and the front-rear direction, the locking claw fixing portion is formed even if a force is applied to the piston member 12 in the pulling direction. It abuts on the inner surface of 56 and does not come off.

The spring portion 28 is long so that the locking claw 32 is located outside the locking claw fixing portion 56 at a position where the head 18 is pressed against the inner peripheral surface 51. Therefore, when the locking portion 30 is pushed in to lock the locking claw 32 to the locking claw fixing portion 56, the spring portion 28 is elastically deformed and contracted, and the head 18 abuts on the inner peripheral surface 51. Be urged to. Therefore, when the locking claw 32 of the piston member 12 is locked to the locking claw fixing portion 56 of the case member 14, the string body 62 is pressed against the inner peripheral surface 51 of the outlet 50 by the head portion 18. It is sandwiched, and the holding protrusion 22 comes into contact with the string body 62 to hold and fix the string body 62. Since the holding protrusion 22 protrudes in the direction away from the apex angle of the head 18, the string body 62 does not slide in the direction in which the string body 62 is pulled out from the outlet 50, that is, in the direction in which the opening such as a bag widens. Further, since the tip of the holding protrusion 22 is slightly rounded, the string body 62 is not damaged.

One of the guide protrusions 20 provided on both the front and back sides of the head portion 18 of the piston member 12 is inserted into the guide recess 58 of the upper surface portion 42, and the other is inserted into the guide groove portion 54 of the lower surface portion 44. Since the guide groove portion 54 and the guide recess 58 are rectangular long in the front-rear direction, the guide protrusion 20 can move in the front-rear direction, and the movement is restricted in the left-right direction. That is, the head 18 can move in the front-rear direction, and the movement is restricted in the left-right direction. The distance between the tips of the guide protrusions 20 located in the front and back directions is formed to be slightly longer than the distance between the inner side surfaces of the upper surface portion 42 and the lower surface portion 44 of the case member 14, that is, the distance between the front and back surfaces of the fitting portion 40. ing. Therefore, when the piston member 12 is inserted into the fitting portion 40, the case member 14 is pushed by the guide protrusion 20 and spreads in the front and back directions. When the guide protrusion 20 coincides with the guide groove portion 54 and the guide recess 58, the guide protrusion 20 is inserted into the guide groove portion 54 and the guide recess 58, the elastic deformation of the case member 14 is restored, and the guide protrusion 20 is the guide groove portion 54 and the guide. It will not come out of the recess 58. Since the surface of the guide protrusion 20 on the connecting member 24 side is formed in a plane substantially parallel to the front and back directions and the left-right direction, the guide groove portion 54 and the guide are guided even if a force is applied to the piston member 12 in the pulling direction. It abuts on the inner surface of the recess 58 and does not come off.

A pull tab 64 such as a tape is attached to the connecting member 24 of the piston member 12. The pull tab 64 may be anything such as a round string or a flap.

This completes the assembly of the piston member 12 and the case member 14, and completes the attachment of the cord stopper 10 to the opening. In the cord stopper 10, the ring portion of the string body 62 along the opening extends from the outlet 50, and both end portions 62a of the string body 62 extend from the insertion port 48.

Next, how to use the cord stopper 10 will be described. When the opening to which the string body 62 is attached is squeezed and closed, the case member 14 is held by one hand, and both end portions 62a of the string body 62 extending from the insertion port 48 are pulled outward with the other hand. .. The holding protrusion 22 is pressed against and held by the string body 62, but since the holding protrusion 22 protrudes in the direction away from the apex angle of the head 18, the holding protrusion 22 is pulled outward from the insertion port 48 by pulling with a strong force. It can slide, the string body 62 on the exit 50 side is shortened, and the opening can be narrowed.

When opening the opening wide, hold the pull tab 64 of the piston member 12 with one hand and pull it away from the bag or the like. Since the case member 14 is fixed to the bag, when the puller 64 of the piston member 12 is pulled, the piston member 12 is slightly pulled out from the insertion port 48 of the case member 14, and the spring portion 28 elastically deforms and contracts, and the head The portion 18 is separated from the inner peripheral surface 51 of the extraction port 50, and the string body 62 is in a slidable state. By simply pulling the puller 64 of the piston member 12 with one hand, only the string 62 is pulled out from the outlet 50 of the case member 14 due to the weight of the bag or the like, the string 62 slides and becomes longer, and the opening is large. You can take items in and out of the bag.

When the pull tab 64 is released at an arbitrary position of the string body 62, the piston member 12 returns to the fitting portion 40 of the case member 14 due to the elasticity of the spring portion 28, holds the string body 62, and opens the bag with an arbitrary size. Can be held at.

When the piston member 12 moves with respect to the case member 14, the guide protrusion 20 of the head 18 of the piston member 12 is guided by the guide groove portion 54 and the guide recess 58, and moves stably in the front-rear direction. Since the holding protrusion 22 projects in a direction away from the apex angle of the head 18, when the opening is narrowed, it can be easily narrowed by pulling both end portions 62a of the string body 62 with a strong force. When unfolding, the string body 62 does not slide even if the opposite side of the string body 62 is pulled with a strong force, which is safe. The opening can be widened by pulling the piston member 12 from the case member 14, and the opening does not inadvertently widen.

The cord stopper 10 does not have to be fixed to an article to be used such as a bag. If it is not fixed, perform the same operation. When widening the opening of a bag or the like, if necessary, hold the opening of the bag with the other hand.

According to the cord stopper 10 of this embodiment, it can be reliably assembled with a simple structure. When the piston member 12 is assembled to the case member 14 and held by the string body 62, the locking portion 30 of the piston member 12 can be directly pushed to be securely locked to the case member 14. That is, the locking portion 30 continuous with the spring portion 28 is exposed in the space 26 adjacent to the connecting member 24 of the piston member 12, and a finger is inserted into the space 26 to push the locking portion 30 to push the piston member 12. The locking claw 32 of the locking portion 30 can be inserted into the locking claw fixing portion 56 of the case member 14 and locked while being inserted all the way, and the case member can be locked more reliably than when the connecting member 24 is pushed and locked. It can be locked to 14. Since the distance between the tips of the locking claws 32 located in the front and back directions of the piston member 12 is slightly longer than the distance between the front and back sides of the fitting portion 40 of the case member 14, the piston member 12 is inserted into the fitting portion 40. At that time, friction is generated by rubbing against the case member 14, and when the connecting member 24 is pushed and locked, the spring portion 28 is stretched, and the locking claw 32 does not reach the locking claw fixing portion 56 even when pushed to the vicinity of the mounting position. Although there is a risk, since the locking portion 30 can be directly pushed, it can be effectively pressed against the frictional force, the locking portion 30 is pushed to the mounting position, and the locking claw 32 is securely engaged. It can be locked to the claw fixing portion 56.

Further, since the holding protrusion 22 protrudes in a direction away from the apex angle of the head 18, when the opening is narrowed, it can be easily narrowed by pulling both end portions 62a of the string body 62 with a strong force. .. On the other hand, when the opening is widened, the string 62 does not slide even if the ring portion of the string 62 is pulled with a strong force, and the opening is widened by pulling the piston member 12 from the case member 14. It is safe because the opening does not inadvertently widen. Therefore, it is easy to open and close an opening such as a bag, and it is easy to use.

When the piston member 12 is pulled from the case member 14, the guide protrusion 20 provided on the head 18 of the piston member 12 moves inside the guide groove portion 54 and the guide recess 58, so that the movement is restricted in the front-rear direction. It can slide stably. Further, it is possible to prevent the piston member 12 from being pulled too strongly and coming off, and when the pulling force is released, the piston member 12 can be reliably returned to the original position. In addition, since the guide groove portion 54 is formed so as to penetrate the lower surface portion 44, the mold is simple, and the guide recess 58 and the guide groove portion 54 can be formed by one mold. The mold can be pulled out and removed.

The code stopper of the present invention is not limited to the above embodiment, and the shape of each member can be freely changed. The shape of the case member 14 may be such that the insertion port side is narrowed and the piston member 12 is pulled while being pressed by the thumb and index finger.
