Description

  The present invention relates to a locking fitting made of a metal wire.

  A carabiner formed of a metal ring is generally known as a locking metal fitting to be hung on a locking object such as a string. The carabiner has a gate that can be opened and closed to open the inside of the metal ring, a spring that closes the gate, and the like. Carabiners are expensive to manufacture because there are many components.

  In order to manufacture an inexpensive locking bracket, it is preferable that the number of components of the locking bracket is small. Patent Document 1 describes a locking ring made of a single wire as a locking bracket with few components, and a locking ring used for a hanging tool of a fall prevention safety device.

With reference to FIG. 14, the latching metal fitting described in patent document 1 is demonstrated.
As shown in FIG. 14A, the locking fitting 101 is formed of a wire 110. The wire 110 includes a first end 111 that is one end formed in a bowl shape, a second end 112 that is the other end formed in a bowl shape, and a first end 111 and a second end 112. And an intermediate portion 113 provided therebetween. Since the intermediate portion 113 is bent in a spiral shape, the first end portion 111 and the second end portion 112 are disposed so as to face each other with the first space S101 interposed therebetween. Furthermore, the wire 110 includes a first straight portion 114 and a first reversing portion 115 that connect the first end portion 111 and the intermediate portion 113, and a second straight portion 116 that connects the second end portion 112 and the intermediate portion 113. And a second reversing unit 117. One wire 110 is continuous in the order of the first end 111, the first reversing portion 115, the first straight portion 114, the intermediate portion 113, the second straight portion 116, the second reversing portion 117, and the second end 112. doing. The first straight line portion 114 and the second straight line portion 116 extending from the intermediate portion 113 are arranged so as not to cross each other and to face each other. The 1st inversion part 115 and the 2nd inversion part 117 form 2nd space S102 which can pass the string R which is a latching object, and mutually cross | intersect 2 times so that 2nd space S102 may be closed. .

  When the string R is passed through the second space S102, the first straight portion 114 and the second straight portion 116 are brought close to each other. When the external force F100 (see FIG. 14B) that brings the first straight portion 114 and the second straight portion 116 closer to each other acts on the wire 110, the first end portion 111 and the second end portion 112 are formed. The first space S101 is reduced, and the second space S102 formed by the first inversion unit 115 and the second inversion unit 117 is increased. By elastically deforming the wire 110 in this way, the first space S101 disappears, and the second space S102 opens toward the outside of the locking fitting 101 as shown in FIG. Therefore, the string R can be passed through the second space S102 from the outside of the locking fitting 101 by bringing the first straight portion 114 and the second straight portion 116 closer to each other. After passing the string R through the second space S102, the first reversing unit 115 and the second reversing unit 117 close the second space S102 so that the string R does not come out of the second space S102. be able to.

(First embodiment)
A first embodiment of the present invention will be described with reference to FIGS. 1 and 2.
As shown in FIG. 1, the locking fitting 1 is composed of a single metal wire 10. As the metal wire 10, for example, a round wire having a diameter of 2 mm and made of a metal material such as spring stainless steel and having a circular cross-sectional shape can be used. The locking metal fitting 1 has, for example, a dimension of about 2.8 cm in the X direction, a dimension of about 0.5 cm in the Y direction, and a dimension of about 6.4 cm in the Z direction.

  The metal wire 10 includes a first end portion 11 as one end, a second end portion 12 as the other end, and an intermediate portion 13 provided between the first end portion 11 and the second end portion 12. And a first connecting portion 14 that connects the first end portion 11 and the intermediate portion 13 and a second connecting portion 15 that connects the second end portion 12 and the intermediate portion 13. One metal wire 10 is continuous in the order of the first end portion 11, the first connecting portion 14, the intermediate portion 13, the second connecting portion 15, and the second end portion 12.

  The first end portion 11 and the second end portion 12 are formed in a bowl shape. The bowl-shaped first end portion 11 and second end portion 12 are arranged so as to close the first space S1 (see FIG. 1A) formed by the first connecting portion 14 and the second connecting portion 15. It is bent toward the first space S1. The first end portion 11 and the second end portion 12 have the same shape, and have an arc-shaped portion so as to have an inner diameter of about 0.6 cm. As shown in FIG. 1C, the portion including the tip surface 11 </ b> A of the first end portion 11, that is, the tip end of the first end portion 11 faces the linear first connecting portion 14. Further, as shown in FIG. 1D, the portion including the distal end surface 12 </ b> A of the second end portion 12, that is, the distal end of the second end portion 12 faces the linear second connecting portion 15. The first end portion 11 and the second end portion 12 form a second space S2 that can be opened toward the first space S1 and through which an object to be locked can be passed. The two spaces S2 overlap each other so as to close.

  The intermediate portion 13 is in the form of a wound spring having an inner diameter of about 2.2 cm. That is, the intermediate portion 13 is formed by winding the metal wire 10 one or more times so as to form a closed third space S3. As the intermediate portion 13 is bent, the first connecting portion 14 and the second connecting portion 15 are arranged so as to extend in the Z direction without intersecting and to face each other via the first space S1. ing. Further, the metal wire 10 is bent so that the distance between the first connecting portion 14 and the second connecting portion 15 decreases as the distance from the intermediate portion 13 increases.

  The metal wire 10 is elastically deformed so that the object to be locked can be taken in and out of the first space S1 through the first end 11 and the second end 12 that overlap each other. That is, the metal wire rod 10 is elastically deformed by applying an external force so that the first end portion 11 and the second end portion 12 are separated from each other in the Y direction. Further, the external force that brings the first connecting portion 14 and the second connecting portion 15 closer to each other acts on the metal wire 10, so that the metal wire 10 has the second space S <b> 2 directed toward the first space S <b> 1. It is elastically deformed to open. As shown in FIG. 1A, when the first end 11 and the second end 12 close the second space S2, the first end 11 and the second end 12 are mutually connected. When viewed from a direction perpendicular to the opposing virtual plane P (see FIG. 1B), the tip of the first end 11 and the tip of the second end 12 overlap.

With reference to FIG. 2, an example of the process of hanging the locking metal fitting 1 on the string R that is the locking object will be described.
First, in order to pass the string R from the outside of the locking metal fitting 1 into the first space S1, as shown in FIG. 2A, an external force F1 that separates the first end portion 11 and the second end portion 12 from each other is applied. In addition to the metal wire 10, the metal wire 10 is elastically deformed. And the string R is moved between the 1st connection part 14 and the 2nd connection part 15 through between the 1st end part 11 and the 2nd end part 12, and the direction of the latching metal fitting 1 is changed 90 degrees. Accordingly, as shown in FIG. 2B, the string R is passed through the first space S1. After passing the string R through the first space S1, both ends 11 and 12 are brought close to each other by the restoring force of the metal wire 10, and the first space 11 is formed by the first end 11 and the second end 12. Closed. Next, as shown in FIG. 2C, an external force F <b> 2 in which the first connecting part 14 and the second connecting part 15 approach each other is applied to the metal wire 10 to elastically deform the metal wire 10. Then, the string R is moved from the first space S1 to the second space S2 through between the tip of the first end portion 11 and the tip of the second end portion 12, and the two are connected by the restoring force of the metal wire 10 The parts 14 and 15 are separated from each other, and the second space S <b> 2 is closed by the first end 11 and the second end 12. In this way, as shown in FIG. 2 (D), the locking fitting 1 is hung on the string R.

The following effects are acquired in the latching metal fitting 1 of this embodiment.
(1) When the external force F2 that brings the first connecting portion 14 and the second connecting portion 15 closer to each other acts on the metal wire rod 10, the metal wire rod 10 is elastically deformed, so that the second space S2 is Opening toward the first space S1. Accordingly, the locking object such as the string R is passed through the first space S1 from between the first end portion 11 and the second end portion 12 that overlap each other, and the metal wire 10 is further elastically deformed. Thus, the first space S1 can be passed through the second space S2. And when the external force F2 does not act with respect to the metal wire 10, since the 2nd space S2 will be in the state closed by the 1st end part 11 and the 2nd end part 12, the latching target object is 2nd. It is possible not to come out of the space S2, and the locking metal fitting 1 can be hung on the locking object. Further, since the second space S2 opens toward the first space S1 of the locking metal fitting 1, even when the locking object comes out of the second space S2, the locking object is Unless the first space S1 comes out, the locking metal fitting 1 cannot be removed from the locking object. Accordingly, it is possible to configure an inexpensive locking metal fitting 1 that is difficult to be detached from the locking object and has few components.

  (2) Since the string R can be taken into and out of the first space S1 through the space between the first end portion 11 and the second end portion 12 that overlap each other, the string R can be passed through the first space S1 from one end. The intermediate portion of the long string R can be passed through the first space S1. That is, the locking metal fitting 1 can be easily hung at an arbitrary location on the long locking object. In addition, the metal wire 10 is elastically deformed so that the locking object such as the string R can be taken into and out of the first space S <b> 1 through the first end portion 11 and the second end portion 12 that overlap each other. For this reason, it is possible to pass the locking object from between the first end portion 11 and the second end portion 12 into the first space S <b> 1 by elastically deforming the metal wire 10. And when the external force F1 does not act on the metal wire rod 10, the first space S1 is closed by the first end portion 11 and the second end portion 12, so that the locking object is the first end. It is possible to prevent the first space S1 from passing through between the portion 11 and the second end portion 12.

  (3) Since the metal wire 10 is bent so that the distance between the first connecting portion 14 and the second connecting portion 15 decreases as the distance from the intermediate portion 13 increases, the first end portion 11 and the second end portion The second space S <b> 2 formed by overlapping 12 with each other can be reduced.

  (4) The intermediate portion 13 is in the form of a wound spring wound one or more times so as to form a closed third space S3. Therefore, by passing an object to be locked such as the string R through the second space S2 and further passing another object to be locked (not shown) through the third space S3, the spaces S2 and S3 that are independent from each other. The object to be locked can be passed through. For this reason, the locking metal fitting 1 can be hung on two locking objects, and the locking objects can be prevented from interfering with each other.

  (5) With respect to the virtual plane P1 where the first end 11 and the second end 12 face each other in a state where the first end 11 and the second end 12 close the second space S2. When viewed from the vertical direction, the tip of the first end 11 and the tip of the second end 12 overlap. For this reason, when the first end portion 11 and the second end portion 12 move along the virtual plane P, the second space S2 can be prevented from being immediately opened.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIGS.
As shown in FIG. 3, the locking fitting 2 is composed of a single metal wire 20. As the metal wire 20, for example, the same round wire as that of the metal wire 10 can be used. The locking metal fitting 2 has, for example, a dimension of about 2.8 cm in the X direction, a dimension of about 0.5 cm in the Y direction, and a dimension of about 7.3 cm in the Z direction.

  The metal wire rod 20 includes a first end portion 21 that is one end, a second end portion 22 that is the other end, and an intermediate portion 23 provided between the first end portion 21 and the second end portion 22. Furthermore, it has the 1st connection part 24 which connects the 1st end part 21 and the intermediate part 23, and the 2nd connection part 25 which connects the 2nd end part 22 and the intermediate part 23. One metal wire 20 is continuous in the order of the first end portion 21, the first connecting portion 24, the intermediate portion 23, the second connecting portion 25, and the second end portion 22.

  The first end 21 and the second end 22 are formed in a bowl shape. The bowl-shaped first end 21 and second end 22 are arranged so as to close the first space S1 (see FIG. 3A) formed by the first connecting portion 24 and the second connecting portion 25. It is bent toward the first space S1. The first end portion 21 and the second end portion 22 have the same shape, and have an arc-shaped portion so as to have an inner diameter of about 2.8 cm. As shown in FIG. 3C, the portion including the distal end surface 21 </ b> A of the first end portion 21, that is, the distal end of the first end portion 21 faces the substantially linear first connecting portion 24. Further, as shown in FIG. 3D, the portion including the tip surface 22 </ b> A of the second end portion 22, that is, the tip end of the second end portion 22 faces the substantially linear second connecting portion 25. The first end portion 21 and the second end portion 22 form a second space S2 that can be opened toward the first space S1 and that allows the object to be locked to pass therethrough. The two spaces S2 overlap each other so as to close.

  The intermediate portion 23 has a spiral spring shape having an inner diameter of about 0.6 cm. That is, the intermediate portion 23 is formed by winding the metal wire 20 one or more times so as to form a closed third space S3. Due to the bending of the intermediate portion 23, the first connecting portion 24 and the second connecting portion 25 are disposed so as to extend in the Z direction without intersecting and to face each other via the first space S1. ing. Further, the metal wire 20 is bent so that the distance between the first connecting portion 24 and the second connecting portion 25 increases as the distance from the intermediate portion 23 increases.

  The metal wire 20 is elastically deformed so that the object to be locked can be taken in and out of the first space S1 through the first end 21 and the second end 22 that overlap each other. That is, the metal wire 20 is elastically deformed by applying an external force so that the first end 21 and the second end 22 are separated from each other in the Y direction. Further, the external force that brings the first connecting portion 24 and the second connecting portion 25 closer to each other acts on the metal wire 20, so that the metal wire 20 has the second space S <b> 2 directed toward the first space S <b> 1. It is elastically deformed to open. As shown in FIG. 3A, in the state where the first end 21 and the second end 22 close the second space S2, the first end 21 and the second end 22 are mutually connected. The tip surface 21A of the first end 21 and the tip surface 22A of the second end 22 are joined together when viewed from the direction perpendicular to the opposing virtual plane P (see FIG. 3B).

With reference to FIG. 4, an example of the process of hanging the locking metal fitting 2 on the string R that is the locking object will be described.
First, in order to pass the string R from the outside of the locking metal fitting 2 to the first space S1, as shown in FIG. 4A, an external force F1 that separates the first end portion 21 and the second end portion 22 from each other is applied. In addition to the metal wire 20, the metal wire 20 is elastically deformed. And the string R is moved between the 1st connection part 24 and the 2nd connection part 25 through between the 1st end part 21 and the 2nd end part 22, and the direction of the latching metal fitting 2 changes 90 degrees. As shown in FIG. 4B, the string R is passed through the first space S1. After passing the string R through the first space S1, the both ends 21 and 22 are brought close to each other by the restoring force of the metal wire 20, and the first end 21 and the second end 22 form the first space S1. Closed. Next, as shown in FIG. 4C, an external force F <b> 2 in which the first connecting portion 24 and the second connecting portion 25 approach each other is applied to the metal wire 20 to elastically deform the metal wire 20. Then, the string R is moved from the first space S1 to the second space S2 through the space between the tip of the first end 21 and the tip of the second end 22, and the two are connected by the restoring force of the metal wire 20 The parts 24 and 25 are separated from each other, and the first space 21 is closed by the first end 21 and the second end 22. In this way, as shown in FIG. 4 (D), the locking fitting 2 is hung on the string R.

In the locking metal fitting 2 of this embodiment, the following effects are acquired.
(6) When the external force F2 that brings the first connecting portion 24 and the second connecting portion 25 closer to each other acts on the metal wire rod 20, the metal wire rod 20 is elastically deformed, so that the second space S2 is Opening toward the first space S1. Therefore, the same effect as (1) can be obtained. That is, since the locking metal fitting 2 is hung on the locking object by passing the locking object through the second space S2, the inexpensive locking metal fitting 2 is less likely to be detached from the locking object and has few components. Can be configured.

  (7) The metal wire 20 is elastically deformed so that the locking object such as the string R can be taken in and out of the first space S1 through the first end 21 and the second end 22 that overlap each other. . Therefore, the same effect as (2) can be obtained. That is, the locking metal fitting 2 can be easily hung at an arbitrary position of the long locking object, and when the external force F1 does not act on the metal wire 20, the locking object is the first end portion. It is possible to prevent the first space S <b> 1 from passing through between the first end 21 and the second end 22.

  (8) The metal wire 20 is bent so that the distance between the first connecting part 24 and the second connecting part 25 increases as the distance from the intermediate part 23 increases. For this reason, the second space S2 formed by overlapping the first end 21 and the second end 22 can be enlarged.

  (9) The intermediate portion 23 has a spiral spring shape that is wound one or more times so as to form a closed third space S3. For this reason, the same effect as said (4) can be acquired. That is, the locking metal fitting 2 can be hung on two locking objects, and the locking objects can be prevented from interfering with each other.

(Third embodiment)
Next, a third embodiment of the present invention will be described with reference to FIGS.
As shown in FIG. 5, the locking fitting 3 is composed of a single metal wire 30. As the metal wire 30, the same round wire as that of the metal wire 10 can be used. The locking fitting 3 has, for example, a dimension of about 3 cm in the X direction, a dimension of about 0.6 cm in the Y direction, and a dimension of about 7.2 cm in the Z direction.

For this reason, by moving the locking object toward the second space S2 along the guide portions 66 and 67, the second space S2 is opened, and the first space S1 is changed to the second space S2. The object to be locked can be easily moved.

  (25) In a state where the first end 61 and the second end 62 close the second space S2, the tips of the first end 61 and the second end 62 are directed toward the second space S2. It is bent. For this reason, the movement of the locking object such as the string R passed through the second space S2 can be restricted by the tips of the first end 61 and the second end 62, and the locking object is The escape from the second space S2 to the first space S1 can be effectively suppressed. It should be noted that not only the tips of both the first end 61 and the second end 62 are bent toward the second space S2, but also the tips of the first end 61 and the second end 62 are Similar effects can be obtained also when bending toward the second space S2.

  The present invention is not limited to the above-described embodiment, and the configuration of the above-described embodiment can be changed as appropriate. For example, the above configuration can be changed as follows, and the following changes can be combined.

  -As long as 2nd space S2 described in the said embodiment can be formed, you may change suitably the shape of the 1st edge part of a metal wire, and the shape of a 2nd edge part. For example, also in the locking metal fitting 6A shown in FIG. 13, the same effect as that of the locking metal fitting 6 in the sixth embodiment can be obtained. The locking metal fitting 6A has a first end portion 61 and a second end portion 62 whose tip is gently bent as compared with the sixth embodiment. Further, for example, the first and second end portions of the bowl shape in the above embodiment have arc-shaped portions, but may have substantially triangular portions. That is, in the present invention, the shape of the “hook shape” is not limited to the above embodiment.

  -As long as 1st space S1 described in the said embodiment can be formed, you may change suitably the shape of the 1st connection part of a metal wire, and the shape of a 2nd connection part. Moreover, as long as a latching bracket can be hung on a latching target object, you may change suitably the dimension of the latching brackets 1-6 described in the said embodiment. That is, the shape of the locking metal fitting may be changed as appropriate, and the dimensions of the spaces S1, S2, and S3 may be changed as appropriate.

  -Enlarge the gap between the first end and the second end of the metal wire that overlap each other, and elastically deform the metal wire without passing through the first end and the second end. You may comprise so that an object can be taken in and out with respect to 1st space.

  -If the effect described in the above embodiment can be obtained, for example, the metal fitting made of a metal material such as iron or aluminum may be used to form the locking metal fitting. In addition, the cross-sectional shape may be a non-circular square line. That is, the material of the metal wire may be changed as appropriate.

  -The structure with which the latching metal fitting in any one embodiment is provided among the said embodiment may be applied to the latching metal fitting in other embodiment. That is, for example, a configuration in which the intermediate portion 23 has a winding spring shape in the first embodiment may be applied to the intermediate portion 33 of the third embodiment.

  If the object to be locked is not removed from the second space S2 described in the above embodiment, the second space S2 is the second space S2 when viewed from the direction perpendicular to the virtual plane P. You may open slightly toward 1st space S1. In other words, in the present invention, “close” means that a state in which the locking object is put in and out of the adjacent space is restricted, and does not mean that the adjacent space is completely partitioned.
