Description

Strap fastener {CORD CLOSURE}

The present invention relates to a fastener attached to an arbitrary position of a rope, a band, or a string (hereinafter, these are referred to as a string) used for setting up a tent, for example.

7 shows an example of setting up a tent. The tent 1 is formed in the shape of a polygon of a predetermined size by a core material (not shown). The tent 1 is installed in a state in which the pulling strings 2 placed along each corner are pulled on the ground side to be in use. maintain. The pulling string 2 is fixed to the anchor member 3 (the absence of this by surrounding trees or rocks, etc.) fixed to the ground at one end 2a, the free end thereof, to thereby fix the tent 1. Keep at tension. In a state where the pulling string 2 is fixed by hanging, the attachment portion to the string 2 is attached to an arbitrary position of the pulling string 2 and by fixing one end 2a of the string 2. And a fastener for enabling the formation of the locking string loop portion 2b between the one end and the one end 2a is used.

8 shows a conventional example of the fastener. The fastener 50 is made of a long thin plate made of resin or metal, and has three holes 51, 52, 53 through which one end 2a of the pulling string 2 penetrates up and down. The upper hole 51 and the middle hole 52 are through holes for attaching the fastener 50 to the pulling string 2, and the lower hole 53 is It is an attachment hole which fixes one end 2a. That is, in this structure, one end 2a penetrates upward through the through hole 51 from the top and the bottom surface as shown by the virtual line of FIG. After being drawn out, the attachment hole 53 is penetrated from the bottom to the top thereof, and then a fall prevention knot 2c is formed at the tip thereof. As a result, the fastener 50 is attached to an arbitrary position of the string 2 by being caught by the edge of the hole when the string 2 is inserted or drawn out through the through holes 51 and 52 to change the direction. In addition, the actual length of the string 2 can be adjusted by varying the amount of pull out of the string portion between the through hole 52 and the attachment hole 53, that is, the size of the string loop portion 2b.

In the fastener 50 as described above, in particular, it is required to be excellent in the locking force on the string 2 and to be able to operate in one touch. However, the conventional fixture 50 has the following problems. That is, in this structure, the fastener 50 is attached to the string 2 in a state in which the string 2 is penetrated from the through hole 51 to the through hole 52. When the diameter of the hole is increased, the string 2 The locking force on the side becomes weak, and conversely, when the diameter of the hole is made small, it becomes difficult to penetrate one end 2a. In the case of the resin, the through-holes 51 and 52 are abrasion-prone and easily shifted in the attached state. In the case of the metal, the through-holes 51 and 52 are not worn. In addition, after the fastener 50 is once attached to the string 2, for example, a draw length of the string loop portion 2b is varied to shorten or lengthen the substantial length of the string 2 (this is referred to as readjustment operation). In such a case, the maneuverability is not good because in such a case, it is necessary to move from the small through-hole 51 to the through-hole 52 while pulling the string 2.

An object of the present invention is to solve the above problems. Specifically, the present invention provides a fastener for a string that can increase the locking force on the string and at the same time make the attaching operation somewhat satisfactory, and can easily perform the readjustment operation described above. Other purposes will be clarified in the following.

The present invention for achieving the above object, as illustrated in Figures 1 to 6, attached to any position of the string (2) used for setting up the tent, etc., one end (2a) of the string (2) In the fastener 4 which enables the formation of the string loop portion 2b between the attachment portion to the string 2 and the one end 2a of the string 2 by fastening, the fastener 4 is And a base (10) forming a fixing portion (12) for fixing one end (2a) of the string (2), and a stopper (20) rotatably connecting the proximal end portion (21) to the base (10). The stopper 20 has a through hole 23 through which one end 2a of the string 2 penetrates from one side of the upper side and the other side to the other side, and is formed in the through hole 23. One end 2a of the string 2 penetrated and drawn out to the other side of the upper and lower surfaces is pulled from the vicinity of the base end from the other side of the upper and lower surfaces to one side again. By rotating with respect to the switch 10, the corresponding part of the strap 2 is sandwiched between the proximal end 21 and the base 10 to enable attachment to the strap 2. Doing.

The fastener 4 described above is used, for example, in the case of fixing the tent string 2 for hanging on the anchor 3 side as shown in FIG. 7. In order to use, one end 2a of the string 2 is penetrated from one side of the through hole 23 to the other side, and the stopper 20 is rotated after drawing out to one side near the base end 21 of the stopper 20. When operated, the corresponding portion of the string 2 is sandwiched between the base end 21 and the base 10, and the fastener 4 is attached to the proper position of the string 2. One end 2a is fixed to the fixing part 12 of the base 10 as in the prior art. Then, the entire length of the string 2 is fixed to the anchor 3 or the like, since the entire length of the string 2 is a length that matches the amount of drawout between the fastener 4 and the fixing portion 12, that is, the size of the string loop portion 2b. It becomes possible. In the readjustment operation, for example, the stopper 20 is rotated to the opposite side to the rotation direction in the state in which the string portion immediately in front of the fastener 4 is pulled out to release the clamping state, and then the string loop portion ( The length of 2b) is changed and rotated again in the sandwiching direction. The feature of this structure is that, on the premise of attaching the fastener 4 along the string 2, it is possible to improve the attachability to the string 2 and to increase the holding force while maintaining the attachability. In that it can. That is, in this structure, the one end 2a is drawn out from the through hole 23 on the stopper 20 side to the base end 21 and is fixed to the fixing part 12 on the base 10 side. The fastener 4 is arranged along the string 2 as in the prior art. In this structure, since the locking force with respect to the string 2 is proportional to the clamping force of the base end 21 (between the base end and the base 10), the diameter of the through hole 23 is enlarged and the one end 2a penetrates. Castle can be secured and can be attached to the string 2 by the one-touch operation of rotation. The readjustment operation can be performed by the rotation of the stopper 20 which is excellent in operability compared to moving the corresponding portion of the string from the through hole having a small diameter to the through hole as in the prior art.

It is more preferable that the present invention described above is embodied as follows.

First, the base 10 and the stopper 20 are arranged in a substantially straight line along the string 2 in a state in which a corresponding portion of the string 2 is sandwiched between the base end 21 and the base 10. Configuration. This reliably specifies the above points, and makes it possible to keep the appearance in the use state beautifully.

Second, the base 10 forms the fixing part by an attachment hole 12 that penetrates one end 2a of the string 2 in the up and down direction and prevents it from falling out, and the stopper 20 The control part 17 which regulates the range of rotation of) is comprised. The attaching hole 12 forms a knot 2c at one end 2a without a dedicated fixing member as in the prior art, so that it can be prevented from coming off. The restricting section 17 makes it possible to maintain the holding state more stably or to improve the convenience of use by regulating the range of rotation.

Third, the base end 21 of the stopper 20 has a locking protrusion 26 for attaching a string, and the base 10 has an approximately c-shaped attachment part 11 corresponding to the base end 21. The attachment part 11 supports the proximal end 21 to the c-shaped walls 15 and 15 so as to be rotatable, and the one end 2a of the string 2 to the bottom face 17 of the c-shaped step. It is the structure which forms the through-hole 18 to penetrate. This can set the above-mentioned clamping force to a desired magnitude | size by the latching protrusion 26, and the clamping part 16 with respect to the base end 21 is provided by the presence of the step | difference bottom face 17 and the through-hole 18. FIG. There is a meaning that it can be secured, and the regulatory unit 17 to be described later can be easily secured.

Fourth, the restricting portion 17 of the base 10 is formed in a thin shape using a part of the stepped bottom face 17 in the c-shape, and is located just in front of the passage hole 18. Configuration. This ensures the rigidity of the restricting portion 17 (which is stronger than the protrusions), and also allows the locking projections 26 arranged in the vicinity of the passage hole 18 to abut so as to restrict the rotation of the stopper 20. Make it possible.

Embodiment of the Invention

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described based on drawing. 1-6 show the fastener for strings of the form of this invention. Among these, FIG. 1 shows an example of use of a fastener, (a) is a view for explaining the assembly to the string, and (b) is a view for explaining the use state. 2 is an external view of the fixture. Fig. 3 shows details of the fastener, where (a) is a plan view, (b) is a bottom view, (c) is a side view, (d) is a left sectional view, and (e) is a right sectional view. FIG. 4A is a cross-sectional view taken along the line A-A of FIG. 3 (a), and FIG. 4 (b) is a cross-sectional view taken along the line B-B of FIG. 5: shows a base, (a) is a top view, (b) is sectional drawing along the C-C line of (a). FIG. 6: shows a stopper, (a) is a top view, (b) is a side view.

[Structure] The fastener 4 in the figure is composed of two parts, the base 10 and the stopper 20, and the stopper 20 is assembled so as to be rotatable with respect to the base 10 by a predetermined angle. The base 10 and the stopper 20 are all made of a resin molded article, but other materials do not interfere. Although the overall size is shown enlarged on the drawing, for example, when the fixture 4 is used for the installation of the tent 1 for 3 to 5 persons in FIG. It is a small one of about 6 mm.

The base 10 has a substantially tongue shape as shown in FIGS. 3 and 5, is formed at one end and is attached to the stopper 20 to be connected to the stopper 20, and is formed at an arc center portion at the other end of the base 10. It has a penetrating attachment hole 12. The attachment hole 12 is formed at intervals from the other end, and because the diameter of the hole is larger than the diameter of the string 2, one end 2a of the string 2 penetrates smoothly from the lower surface side to the upper surface side. On the upper surface side, a plurality of small protrusions 14 are formed around the attachment hole 12, and the horizontal grooves 13 are arranged in a direction orthogonal to the small protrusions 14 from the other end toward the attachment hole 12. ) Is formed. This lateral groove 13 accepts the fall prevention knot 2c formed at one end 2a as shown in FIG. The attachment part 11 is formed in the substantially C shape which cut | disconnected the middle part from the top side at the one end side, and corresponds to the wall part 15 of both sides which correspond to both sides of a c-shape, and a c-shaped middle piece part. It is partitioned into the step part bottom surface 17 which has the clamping part 16 and the passage hole 18 in a C-shaped inner lower part. The dimension between both wall parts 15 is a width dimension corresponding to the base end 21 of the stopper 20 mentioned later. Each wall portion 15 is formed with a shaft hole 15a formed through the coaxial line, and a tapered guide portion 15b cut out from the upper surface side to the vicinity of the shaft hole 15a. The clamping portion 16 is formed of an inclined surface that is inclined toward one end toward the lower side as shown in Fig. 5 (b), and the corresponding portion of the through hole 18 formed on the stepped bottom surface 17 and the surface thereof are To match. That is, the stepped bottom surface 17 is a portion which becomes the restricting portion of the present invention, and lacks a portion corresponding to the front side in the c-shape and is missing by the passage hole 18 penetrating the clamping portion 16 side up and down. It is formed in thin elongate shape. Moreover, the clamping part 16 is elastically deformed slightly by the cavity part 19 cut | disconnected in concave shape from the lower surface side.

3 and 6, the stopper 20 has a plate shape thinner than the base 10, and the base end 21 side is accommodated in the c-shape of the attachment portion 11 described above, and the tip end 22 is formed. The side is formed in an arc shape, and has a through hole 23 at approximately halfway between the base end 21 and the tip end 22. In addition, while the periphery of the upper surface side is formed one step higher than the center part, the base end 21 has entered into the front end side rather than the rear end of the edge part 24 between the edge parts 24 formed one step high. It is formed. The proximal end 21 is located on both sides and protrudes from the corresponding edge portion 24 so as to protrude rearward from an axis line between the shaft portion 25 fitted with the shaft hole 15a and an axis connecting the two shaft portions 25. It has a latch 26. The locking projection 26 is formed of an upper arc portion 26a and a lower inclined portion 26b as shown in Fig. 4A. The connecting portion between the arc portion 26a and the inclined portion 26b forms an acute angle, and as described later, the inclined portion is inclined in a state where the stopper 20 is connected through the fitting between the shaft portion 25 and the shaft hole 15a. The part 26b abuts against the stepped bottom face 17, which is a restricting part, to restrict the rotation of the stopper 20 in the downward direction, and the connection part (projection part) between the arc part 26a and the inclined part 26b is a clamping part ( 16, the lock position of the strap 20 of the stopper 20 that most closely approaches. When the stopper 20 is rotated counterclockwise from its lock position as shown in Fig. 1 (a), the protruding portion of the locking projection 26 is far from the clamping portion 16 so that the entire passage hole 18 is exposed. . In addition, a plurality of slip preventing protrusions 27 are formed on the upper surface of the tip 22 side.

When the above stopper 20 pushes both shaft portions 25 into the corresponding guide portions 15b, both shaft portions 25 are fitted into the shaft holes 15a while elastically displacing the wall portions 15. It is rotatably connected with respect to the base 10 by a predetermined angle. The rotation range of the stopper 20 in this structure is from the locking release position at which the stopper 20 completely opens the passage hole 18 as shown in FIG. It is about 45 degrees between the locking position which covers a part of the passage hole 18 of b) with the protrusion part of the locking protrusion 26. As shown in FIG. In the locking release position, the bottom surface of the stopper 20 is regulated by contacting the end face of the stepped bottom surface 17, which is the restricting portion. In the locking position, the bottom surface 17 of the inclined portion 26b is the restricting portion. The position is controlled by contacting the edge of the end face and the inner surface of the head).

[Use Example] FIG. 1 is a cross-sectional view assuming a case where the above fastener 4 is applied to the portion D of FIG. 7. The fastener 4 penetrates the one end 2a of the string 2 to the upper surface side under the through-hole 23, as shown in FIG. 1 (a), and again exposes the passage hole 18 exposed to the base end 21. After making it penetrate through and drawing it out largely, this time it draws out from below through the attachment hole 12, and builds a knot 2c, and the string loop part 2b between the attachment hole 12 and the passage hole 18 is carried out. ), The stopper 20 is attached to the appropriate position of the string 2 by rotating from the locking release position to the locking position of Fig. 1 (b). The string loop portion 2b determines the size of the string loop portion 2 by the biting action of the locking projection 26 on the string 2 and the anti-falling action of the knot 2c, and determines the string 2 to a predetermined length. . In this structure, in the state where the string 2 entered the through-hole 18, the latching protrusion 26 fits the corresponding part of the string 2 between the clamping part 16. As shown in FIG. The clamping force is an inclined surface in which the clamping portion 16 extends downward, and the clamping portion 16 clamps the string 2 between the locking projections 26 by a wedge action. Due to the presence of 19), the elastic force is slightly displaced, and the repulsive force at that time can be obtained.

In addition, the string 2 holds the tent 1 at a predetermined tension by the string loop portion 2b formed by the fastener 4 being caught by the anchor 3 or the like of FIG. 7. In the readjustment operation described above, after the stopper 20 is rotated from the locked position to the unlocked position in the state where the string 2, which is higher than the fastener 4 is pulled out, the release state is released. The string 2 is pulled toward the string loop portion 2b or pulled upwards of the fastener 4 to variably adjust the size of the string loop portion 2b, and the stopper 20 is rotated again in the locking position direction. In this variable adjustment, the stopper 20 can be rotated and the one-touch operation can be performed in that the strap 2 can be easily moved in the pulling direction by increasing the diameter of the through hole 23.

In addition, the fastener 4 of this invention should just be equipped with the component specified in Claim 1, The shape and size of the base 10, the stopper 20, etc. can be variously modified with reference to this. In addition, the use and the form of use are not limited to the tent 2 for the tent setting of FIG. 7, and any strings are similarly applied, and the strings do not necessarily have to be a single line, and may be used in two (two lines). .

As described above, in the fastener for strings of the present invention, since the stopper is rotated with respect to the base and the corresponding portion of the string is held between the base end of the stopper and the base, the locking force on the string can be increased. As a result, the attaching operation and the readjustment operation to be attached to the string can be performed with one touch, which is convenient for use and the product value is also improved compared with the conventional structure.
