Description

  The present invention relates to a technique of a connector for a pull switch operating body.

  Conventionally, a pull switch has been used in a hanging type lighting fixture attached to a ceiling or the like. As shown in FIG. 11, the pull switch main body 53 is provided inside the lighting fixture 51, and a pull switch operating body 54 that is suspended from the pull switch main body 53 is pulled to operate between the contacts in the pull switch main body 53. Are opened and closed, and a plurality of lighting state mode switching operations such as blinking and switching of the lamp of the lighting fixture 51 are performed. As shown in FIG. 12, the pull switch operating body 54 is directly attached to the pull switch main body 53 and led out from the lead hole 57 of the pull switch main body 53, and the user grips and pulls it. The upper operation body 55 and the lower operation body 56 are connected to each other by a connecting tool 61.

  The connector 61 is formed by forming a metal wire in a substantially S shape, and has an upper locking portion 62 and a lower locking portion 63, and an upper operating body 55 is provided on the upper locking portion 62. The lower operation body 56 is connected to the lower locking portion 63. A gap is formed between the upper locking portion 62 and the lower locking portion 63, and when the upper operation body 55 is connected, the ring-shaped portion 55 a formed at the end of the upper operation body 55 is connected to the upper locking portion 62. The upper locking portion 62 is caulked through the gap, and the gap is closed and connected. The connection between the lower locking portion 63 and the lower operation body 56 is also performed by the same caulking process.

  By the way, a large tensile load may be applied to the pull switch operating body 54 of the pull switch 52, and if a pull load acts on the pull switch main body 53, the pull switch main body 53 may be damaged. Therefore, when a predetermined tensile load or more is applied to the lower operation body 56, the upper locking portion 62 and the lower locking portion 63 are extended and deformed so that the upper operation body 55 and the lower operation body 56 are separated. Thus, a large tensile load is prevented from being applied to the pull switch body 53.

  Further, when the upper locking portion 62 of the connector 61 extends and deforms first and the upper operation body 55 comes off earlier than the lower operation body 56, the upper operation body 55 is moved to the pull switch body 53 with a disengagement momentum. In some cases, it is suddenly pulled back toward the inside through the outlet hole 57 of the pull switch body 53. In this case, it becomes difficult to pull out the upper operation body 55 from the lead-out hole 57 again, and the pull switch may be disabled.

For this reason, the tensile strength of the upper locking portion of the substantially S-shaped coupling tool is set larger than the tensile strength of the lower locking portion, and the coupling tool is formed wider than the outlet hole of the pull switch body. Has been developed (see, for example, Patent Document 1). According to this connection tool, when a large tensile load is applied to the lower operation body, the lower locking portion extends and deforms before the upper locking portion, and the connection tool is unlikely to come off the upper operation body. Even if the upper operating body is suddenly pulled back toward the pull switch body together with the connecting tool, the connecting tool is formed wider than the outlet hole of the pull switch body. It is prevented from entering inside.

  However, in the above-mentioned conventional coupler, for a static tensile load, the lower locking portion having a low tensile strength extends and deforms earlier than the upper locking portion, and the lower operation body comes off first. When a large tensile load is applied instantaneously, the order may not be removed. For example, if a child jumps to the pull switch operation body and pulls it, and if a tensile load that greatly exceeds the assumed tensile load is momentarily applied to the connector, the stage starts from the lower locking part with low tensile strength. In some cases, the lower locking portion and the upper locking portion are stretched and deformed substantially simultaneously, and as a result, the upper operation body may first come off the coupling tool.

  In addition, the above-described conventional connecting tool having a substantially S-shape is connected to the upper operating body and the lower operating body by caulking the upper engaging portion and the lower engaging portion, respectively. The work is often performed, and depending on the skill level of the worker, metal fatigue may occur in the metal wire of the connector due to caulking. In this case, even if the tensile strength of the upper locking portion of the coupler is set to be larger than the tensile strength of the lower locking portion, the actual tensile strength of the coupler after the caulking process will vary, and the upper In some cases, the tensile strength of the stop portion is lower than the tensile strength of the lower locking portion.

  Therefore, according to the above conventional coupler, even when the tensile strength of the upper locking portion is set to be larger than the tensile strength of the lower locking portion, a very large instantaneous tensile load is applied, or caulking When the metal fatigue is caused by the above, there is a case where the upper engaging portion is deformed by extension and the upper operation body is detached from the connecting tool before the lower operation body. Since the connecting tool is pulled downward by a strong force by the lower operation body, the connecting tool may collide with an operator or the like below.

  The present invention has been made in view of the above problems, and even when a pull load is applied to the pull switch operation body, the lower operation body surely comes off from the coupling tool before the upper operation body. An object of the present invention is to provide a connector for a pull switch operating body having a high height.

  The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described.

  That is, according to the first aspect of the present invention, there is provided a pull switch operating body connecting tool for connecting the upper operating body and the lower operating body of the pull switch operating body, and an insertion space for inserting the upper operating body is formed. An upper connecting part for connecting the upper operating body, and a first connecting part and a second connecting part which are respectively continuous on both sides of the upper connecting part, and the first connecting part and the second connecting part. The end portion has a gap through which the upper operating body and the lower operating body can pass, respectively, and the first connecting portion and the second connecting portion are formed in a multi-layered state, and the lower operating body is inserted therethrough. A lower connection part for connecting the lower operation body, which forms a space, and formed between the upper connection part and the lower connection part, and the movement of the upper operation body to the lower connection part, and the lower operation body While restricting movement to the upper connection part, And a connecting member of the pull switch operating body and having a partition portion for passing the upper operating body elastically deformed, the by push body.

  According to a second aspect of the present invention, there is provided a pull switch operating body connecting tool for connecting the upper operating body and the lower operating body of the pull switch operating body, wherein the upper operating body is inserted by bending a metal wire. An upper connecting part for connecting the upper operating body, in which an insertion space is formed, and a gap through which the upper operating body and the lower operating body can pass through both ends of the metal wire continuous from the upper connecting part are secured. A lower operating body that is bent to form a first connecting portion and a second connecting portion, and the first connecting portion and the second connecting portion are formed in a stacked state to form an insertion space through which the lower operating body is inserted. It is formed between the lower connecting part for connecting, the upper connecting part and the lower connecting part, and restricts the movement of the upper operating body to the lower connecting part and the movement of the lower operating body to the upper connecting part. In addition, it is elastic by pressing the upper operating body. A partition portion for passing the upper operating body to form, and the coupling of the pull switch operating body and having a.

  As effects of the present invention, the following effects can be obtained.

  According to the first aspect of the present invention, the lower connecting portion includes a first connecting portion and a second connecting portion that are respectively continuous on both sides of the upper connecting portion, and the first connecting portion and the second connecting portion are A gap through which the upper operating body and the lower operating body can pass is secured at each end, and an insertion space through which the lower operating body is inserted is formed in the first connecting portion and the second connecting portion in a stacked state. Forming. For this reason, both ends of the end portions that cause elongation deformation are arranged in the lower connecting portion, and no end portions as in the case of the S-shaped connecting tool are arranged in the upper connecting portion. When a tensile load is applied, the first connecting portion and the second connecting portion of the lower connecting portion are stretched and deformed, and the lower operation body is detached from the lower connecting portion, thereby preventing the pull switch from being damaged. On the other hand, an end portion that causes elongation deformation is not arranged in the upper connecting portion, and even when a large tensile load is momentarily applied, the upper operation body does not come off from the upper connecting portion.

  Further, since the upper connecting portion does not have an end portion, when the upper operating body is connected to the upper connecting portion, the upper operating body is moved by elastically deforming the first connecting portion, the second connecting portion, and the partitioning portion. The upper operating body is connected to the upper connecting portion by passing the upper operating portion. For this reason, even if it is a case where it forms with a metal wire, when connecting an upper operation body to an upper connection part, a caulking process is unnecessary and there is no fall of the tensile strength of an upper connection part by metal fatigue. Therefore, even when a large tensile load is momentarily applied, the upper operating body does not come off from the upper connecting portion.

  Further, as described above, the upper operating body is inserted from the lower connecting portion and moved to the upper connecting portion so that the upper connecting portion can be connected. The free movement of the body to the lower connection part and the free movement of the lower operation body to the upper connection part are restricted. For this reason, it can prevent that an upper operation body moves to a lower connection part carelessly, and a lower operation body moves to an upper connection part carelessly. Therefore, the lower operating body is securely connected to the lower connecting portion, and when a tensile load is applied, the lower operating body can be detached from the lower connecting portion to prevent the pull switch from being damaged. Further, the upper operation body is securely connected to the upper connection portion, and even when a large tensile load is momentarily applied, the upper operation body and the connection tool are not detached.

  From the above, it is possible to provide a highly secure connecting device for a pull switch operating body in which the lower operating body is surely detached from the connecting device before the upper operating body when a tensile load is applied to the pull switch operating body.

  According to the second aspect of the present invention, the coupler of the pull switch operating body is formed by bending a metal wire, and the lower connecting portion is connected to both ends of the metal wire continuous from the upper connecting portion. The first connecting part and the second connecting part are bent while securing a gap through which the upper operating body and the lower operating body can pass, and the first connecting part and the second connecting part are formed in a multi-layered state. An insertion space for inserting the operating body is formed. For this reason, the ends of the metal wire that causes elongation deformation are arranged in the lower connecting portion at both ends, and the ends of the metal wire as in the case of the S-shaped connector are arranged in the upper connecting portion. Not. When a tensile load is applied, the first connecting portion and the second connecting portion of the lower connecting portion are stretched and deformed, and the lower operation body is detached from the lower connecting portion, thereby preventing the pull switch from being damaged. On the other hand, the end portion of the metal wire that causes elongation deformation is not arranged in the upper connecting portion, and even when a large tensile load is momentarily applied, the upper operation body does not come off from the upper connecting portion. .

  In addition, since the upper connecting portion is formed by bending a part of the metal wire, and the end of the metal wire is not disposed, when connecting the upper operation body to the upper connecting portion, the first connecting portion The upper operating body is connected to the upper connecting portion by elastically deforming the second connecting portion and the partitioning portion and allowing the upper operating body to pass therethrough. For this reason, when connecting an upper operation body to an upper connection part, a caulking process is unnecessary and there is no fall of the tensile strength of an upper connection part by metal fatigue. Therefore, even when a large tensile load is momentarily applied, the upper operating body does not come off from the upper connecting portion.

  Further, as described above, the upper operating body is inserted from the lower connecting portion and moved to the upper connecting portion so that the upper connecting portion can be connected. The free movement of the body to the lower connection part and the free movement of the lower operation body to the upper connection part are restricted. For this reason, it can prevent that an upper operation body moves to a lower connection part carelessly, and a lower operation body moves to an upper connection part carelessly. Therefore, the lower operating body is securely connected to the lower connecting portion, and when a tensile load is applied, the lower operating body can be detached from the lower connecting portion to prevent the pull switch from being damaged. Further, the upper operation body is securely connected to the upper connection portion, and even when a large tensile load is momentarily applied, the upper operation body and the connection tool are not detached.

  Next, embodiments of the invention will be described with reference to the drawings.

  A pull switch operating body connector (hereinafter referred to as “connector”) 11 according to a first embodiment of the present invention will be described with reference to the drawings. 1 is a front view of a connector 11 according to a first embodiment of the present invention, FIG. 2 is a rear view of the connector 11, FIG. 3 is a side view seen from the direction of arrow A in FIG. 1, and FIG. FIG. 5 is a front view showing a state in which the annular portion 55a at the tip of the upper operation body 55 is pushed between the first connecting portion 23 and the second connecting portion 24.

  6 is a front view showing a state in which the upper operating body 55 is connected to the upper connecting portion 21 of the connecting tool 11, FIG. 7 is a front view showing a state in which the connecting tool 11 and the pull switch operating body 54 are connected, and FIG. FIG. 9 is a front view of a state in which a tensile load is applied to the lower operation body 52 of FIG. 52, and FIG. 9 is a front view of a state in which the lower operation body 56 is detached from the lower connection portion 22.

  The connector 11 according to the present embodiment is used for the pull switch 52 of the hanging type lighting fixture 51. In the following description, the pull switch 52 is used for the hanging type lighting fixture 51 in the vertical direction. It shall mean the up-and-down direction in the state which is.

  As shown in FIG. 1, the connector 11 is formed by bending a stainless steel wire rod having a diameter of 0.7 mm into an “8” shape when viewed from the front, and an upper connecting portion 21, a lower connecting portion 22, a partition portion 31, and a guide. The both ends of the stainless steel wire are arranged in the lower connecting portion 22. By using a stainless steel material as the material of the wire rod, the aesthetic appearance of the connector 11 is improved and it is difficult to rust. Therefore, the aesthetic appearance of the lighting fixture 51 using the pull switch can be improved over a long period of time. As a material for the connector 11, a metal material such as steel can be used in addition to stainless steel. A resin material can also be used as the material of the connector 11. As the resin material, a hard resin having elasticity is preferable.

  The upper connecting portion 21 is a portion for connecting the upper operation body 55. As shown in FIGS. 1 and 2, the upper connecting portion 21 is formed in a ring shape by bending a part of a stainless steel wire, and an insertion space through which the upper operation body 55 is inserted is formed. The diameter of the annular portion is about 5 to 6 mm, but can be changed as appropriate to suit the pull switch 52 used. In addition, although the curved part of the upper connection part 21 was formed in cyclic | annular form, what is necessary is just a shape with which the insertion space where the upper operation body 55 is penetrated, such as an inverted U shape, is ensured.

  As shown in FIGS. 1 and 2, the upper connecting portion 21 is located below the upper connecting portion 21 and between the lower connecting portion 22 and the lower connecting portion 22. Part 31 is formed. The partition part 31 crosses the continuous stainless steel wire rods from the upper connecting part 21 so as to approach each other, and as shown in FIG. 4, the stainless steel wire rods are in close contact with each other. The partition part 31 restricts the movement of the upper operation body 55, which will be described later, to the lower connection part 22 and the movement of the lower operation body 56, which will be described later, to the upper connection part 21, and also makes the upper operation body 55 a close contact portion of the intersection. By being pushed in, it is elastically deformed, and the gap is widened to allow the upper operation body 55 to pass through. In addition, since the partition part 31 is formed by making a stainless steel wire cross | intersect, the partition part 31 can be formed integrally with the upper connection part 21 and the lower connection part 22. FIG.

  Since the partition part 31 restricts the free movement of the upper operation body 55 to the lower connection part 22 and the free movement of the lower operation body 56 to the upper connection part 21, the upper operation body 55 is not prepared. Therefore, it is possible to prevent the lower operating body 56 from moving to the upper connecting portion 21 inadvertently. Therefore, the lower operation body 56 is securely connected to the lower connection portion 22, and when a tensile load is applied, the lower operation body 56 is detached from the lower connection portion 22 to prevent the pull switch 52 from being damaged. be able to. Further, the upper operation body 55 is reliably connected to the upper connection portion 21, and the upper operation body 55 and the connection tool 11 are not detached even when a large tensile load is momentarily applied.

  Further, since the stainless steel wire rod is in close contact with the partition portion 31 when the tensile force is applied and the lower operation body 56 is detached from the connector 11, the connector 11 moves violently by reaction. In addition, the upper operation body 55 is unlikely to pass through the partition portion 31, and the upper operation body 55 and the connector 11 are prevented from being detached.

  Next, as shown in FIGS. 1 and 2, a lower connecting portion 22 is formed below the partition portion 31. The lower connecting portion 22 is a portion for connecting a lower operation body 56 described later. The lower connecting portion 22 includes a first “connecting portion” 23 having a substantially “inverted G” shape and a second connecting portion 24 having a substantially “C” shape. As shown in FIG. 1, the 1st connection part 23 curves the stainless steel wire which continues through the partition part 31 from the illustration left side of the upper connection part 21, and is formed in a substantially cyclic | annular form. The diameter of the substantially annular portion is 7 to 8 mm, but can be changed as appropriate to match the pull switch 52 used. The end of the annular portion is not a closed shape, but a shape in which a part thereof is opened to secure a gap through which the upper operation body 55 and the lower operation body 56 can pass. A guide portion 41 described later is formed at the end portion of the first connecting portion 23.

  Further, as shown in FIG. 2, the second connecting portion 24 is bent in the direction opposite to the first connecting portion 23. A stainless steel wire continuous from the left side of the upper connecting portion 21 through the partitioning portion 31 is bent in a right-hand direction and formed into a substantially annular shape. The diameter of the substantially annular portion is the same as that of the first connecting portion 23. Further, similarly to the first connecting portion 23, the diameter of the annular portion can be appropriately changed so as to match the pull switch 52 to be used. The end of the annular portion is not a closed shape, but a shape in which a part thereof is opened to secure a gap through which the upper operation body 55 and the lower operation body 56 can pass. As shown in FIGS. 1, 2, and 3, the first connecting portion 23 and the second connecting portion 24 are formed so as to overlap with each other in a front view, and the insertion space through which the lower operation body 56 is inserted. Is forming.

  The upper connecting portion 21 has a diameter of about 5 to 6 mm, the lower connecting portion 22 has a diameter of about 7 to 8 mm, and the lower connecting portion 22 has a larger diameter than the upper connecting portion 21. Since the lower connecting portion 22 is formed larger than the upper connecting portion 21, the lower connecting portion 22 and the upper connecting portion 21 can be easily distinguished. Therefore, when the upper operation body 55 and the lower operation body 56 are connected by the connector 11, an error in the attachment positions of the upper operation body 55 and the lower operation body 56 is prevented. For this reason, when a tensile load is applied to the pull switch operation body 54, the lower operation body 56 is surely detached from the connection tool 11 before the upper operation body 55, and the connection tool 11 with high safety can be obtained. Moreover, since the center of gravity is downward, the posture is stable and the connector 11 is not easily turned upside down.

  Next, as shown in FIGS. 1 and 2, the guide portion 41 is formed at the end of the first connecting portion 23 as described above. The guide portion 41 is a portion that guides the upper operation body 55 and the lower operation body 56 when the upper operation body 55 and the lower operation body 56 are pushed between the first connection portion 23 and the second connection portion 24. The guide portion 41 is formed by bending the end portion of the first connecting portion 23 toward the center of the lower connecting portion 22.

  Since the guide part 41 when the upper operation body 55 and the lower operation body 56 are pushed in is formed at the end of the first connection part 23 of the lower connection part 22, the upper operation body 55 and the lower operation body 56 are connected to the first operation part 55. It becomes easy to push in between the connecting part 23 and the second connecting part 24. Thereby, the connection of the upper operation body 55 to the upper connection portion 21 and the connection of the lower operation body 56 to the lower connection portion 22 are facilitated, and the connection of the pull switch operation body 54 and the connector 11 is facilitated.

  Next, the case where the said connecting tool 11 and the pull switch operation body 54 are connected is demonstrated. The upper operating body 55 of the pull switch operating body 54 is a part that is directly attached to the pull switch main body 53 and led out from the lead-out hole 57 of the pull switch main body 53 (see FIG. 12). A ring-shaped portion 55a to be connected to the connecting portion 23 is formed. Further, the lower operation body 56 of the pull switch operation body 54 is a portion that is gripped and pulled by the user, and a ring-shaped portion 56a that is connected to the second connection portion 24 is formed at the tip (see FIG. 12). In the present embodiment, the upper operation body 55 and the lower operation body 56 are string bodies, but in addition to the string body, a chain, a metal wire such as a piano wire, a member in which a through hole for connection is formed in a metal plate, and the like. Even so, the present invention can be applied.

  First, the case where the upper operation body 55 is connected to the upper connecting portion 21 of the connecting tool 11 will be described.

  As described above, the guide portion 41 is formed at the end of the first connecting portion 23, and the guide portion 41 is passed through the ring-shaped portion 55a at the tip of the upper operation body 55 as shown in FIG. It pushes in between the 1st connection part 23 and the 2nd connection part 24. FIG. The first connecting portion 23 and the second connecting portion 24 are expanded by elastic deformation by being pushed in, and the first connecting portion 23 can be passed through the ring-shaped portion 55a of the upper operation body 55. Then, the ring-shaped portion 55 a of the upper operation body 55 is moved to the partition portion 31.

  Next, in the partition part 31, the stainless steel wire material continuous from the upper connecting part 21 intersects in a close contact state, and the stainless steel wire material is elastically deformed by pushing the upper operation body 55 between the close contact parts of the wire material. Thus, the gap is widened and the upper operation body 55 can be passed. When the partition portion 31 is passed, as shown in FIG. 6, the ring-shaped portion 55 a at the tip of the upper operation body 55 reaches the upper connection portion 21, and the connection between the upper operation body 55 and the upper connection portion 21 is completed.

  As described above, the upper connecting portion 21 is formed by curving a part of a stainless steel wire, and both ends of the stainless steel wire are not arranged. For this reason, when connecting the upper operation body 55 to the upper connection part 21, the first connection part 23, the second connection part 24, and the partition part 31 are elastically deformed to pass the upper operation body 55, thereby allowing the upper operation body 55 to pass. The unit 21 and the upper operation body 55 are connected. When the upper operating body 55 is connected to the upper connecting portion 21, caulking is not required, and there is no decrease in the tensile strength of the upper connecting portion 21 due to metal fatigue. Therefore, as will be described later, even when a large tensile load is momentarily applied to the pull switch operating body 54, the upper operating body 55 does not come off the upper connecting portion 21.

  Next, the case where the lower operation body 56 is connected to the lower connection portion 22 of the connector 11 will be described. As in the case of the upper operation body 55, the guide portion 41 is passed through the ring-shaped portion 56 a at the tip of the lower operation body 56 and is pushed between the first connection portion 23 and the second connection portion 24. The first connecting portion 23 and the second connecting portion 24 are expanded by elastic deformation by being pushed in, and the first connecting portion 23 can be passed through the ring-shaped portion 56 a of the lower operation body 56. Then, when the ring-shaped portion 56a of the upper operation body 55 is moved and passed through the end portion of the second connection portion 24, the ring-shaped portion 56a at the tip of the lower operation body 56 reaches the lower connection portion 22 as shown in FIG. Then, the connection between the lower operation body 56 and the lower connection portion 22 is completed, and the connection between the connector 11 and the pull switch operation body 54 is completed.

  As described above, when the lower operation body 56 is connected to the lower connection portion 22, the first connection portion 23 and the second connection portion 24 are elastically deformed to pass through the lower operation body 56, so that the lower connection portion 22. Are connected to the lower operating body 56. For this reason, when connecting the lower connection part 22 and the lower operation body 56, a crimping process is unnecessary and there is no fall of the tensile strength of the lower connection part 22 by metal fatigue. Therefore, the set tensile strength of the lower connecting portion 22 can be ensured.

  Next, a case where a large tensile load is applied to the pull switch operating body 54 of the pull switch 52 in a state where the connecting tool 11 and the pull switch operating body 54 are connected will be described. As shown in FIG. 8, when a large tensile load is applied to the lower operation body 56 in the direction of the arrow shown in the drawing, the ends of the first connection portion 23 and the second connection portion 24 to which the lower operation body 56 is connected are lowered. Deforms and deforms. As shown in FIG. 9, the end portions of the first connecting portion 23 and the second connecting portion 24 are further extended and deformed downward, and the lower operating body 56 is detached from the lower connecting portion 22, and the upper operating body 55 and the lower operating body 56. And are separated. Thereby, it is possible to prevent a large tensile load from being applied to the pull switch body 53.

  As described above, the end portions of the stainless steel wire material that causes elongation deformation are both disposed at the lower connecting portion 22, and the upper connecting portion 21 has a stainless steel wire material as in the case of an S-shaped connector. The end of is not arranged. For this reason, when a tensile load is applied, the first connecting portion 23 and the second connecting portion 24 of the lower connecting portion 22 are stretched and deformed, and the lower operation body 56 is detached from the lower connecting portion 22 and the pull switch 52 is moved. Damage or the like can be prevented. On the other hand, the upper connecting portion 21 is not provided with an end portion of a stainless steel wire that causes elongation deformation. Even when a large tensile load is momentarily applied, the upper operation body 55 is separated from the upper connecting portion 21. It will not come off.

  In addition, an Example is not limited above, For example, you may change as follows.

  In the above embodiment, the diameter of the lower connecting portion 22 is larger than that of the upper connecting portion 21, but the present invention is not limited to this, and the upper connecting portion 21 and the lower connecting portion 22 may have substantially the same shape. 21 may be larger than the lower connecting portion 22.

  Although the partition part 31 cross | intersects the stainless steel wire which continues from the upper connection part 21, it is not limited to this, What is necessary is just a shape which made the wire approach mutually. For example, as shown in FIG. 10, a bent portion 32 may be formed by bending a part of the wire continuous from the upper connecting portion 21 so that the bent portions 32 are close to each other.

  Conventionally known bending means can be used as the means for manufacturing the connector 11 using a metal material such as a stainless steel wire. Moreover, about the manufacturing means of the coupling tool 11 using a resin raw material, conventionally well-known resin molding means, such as an integral molding means by an injection molding means, can be used.

  The pull switch operating body 54 and the connecting tool 11 are connected by forming ring-shaped portions 55 a and 56 a at the end portions of the upper operating body 55 and the lower operating body 56, and connecting them between the first connecting portion 23 and the second connecting portion 24. However, the present invention is not limited to this, and the pull switch operating body 54 and the connector 11 may be connected by binding the pull switch operating body 54 to the upper connecting portion 21 and the lower connecting portion 22.
