Japanese Utility Model Publication No. 60-114494 (specifications, FIGS. 1 to 3) JP 2003-42109 A (paragraph numbers [0020] to [0029], FIGS. 1 to 4)

  Since the cord clip described in Patent Document 1 presses and holds the cord with the urging force of the spring, the cord is satisfactorily held when the tip of the clip is in a closed state, but the tip of the clip is opened. When operated in the direction, the pressing force of the cord decreases and the holding position of the cord is likely to change. Moreover, in this patent document 1, since it is a structure which requires a through-hole and a processus | protrusion, it can be considered that manufacture and an assembly take time. Moreover, since the through-hole and the protrusion protrude, the breakage easily occurs.

  Since the cord clip described in Patent Document 2 has a structure in which the cord is sandwiched and held by the cord locking portion, the cord holding position does not change in conjunction with the operation as in Patent Document 1. It is. However, in Patent Document 2, since the cord is simply sandwiched and held by the cord locking portion, when an external force such as tension acts on the cord, the cord comes off from the locking portion, and the function of the cord clip is lost. Was also considered.

  In order to eliminate such an inconvenience, it is conceivable to form a cord support portion that presses and supports the cord with an urging force such as a spring against one of the first sandwiching body and the second sandwiching body. In the case of using the urging force, there is a room for improvement because the number of parts is increased, for example, a movable part is required, and the assembly is troublesome.

  An object of the present invention is to construct a cord clip that favorably supports a cord.

A feature of the present invention is that the first and second clamping bodies are biased in the closing direction by a biasing member at the clamping end portions of the first clamping body and the second clamping body that are connected to each other so as to be swingable and openable. A cord clip having a cord support portion on one side,
A first connection piece projecting from the first sandwiching body and a second connection piece projecting from the second sandwiching body at positions sandwiched between opposing surfaces of the first sandwiching body and the second sandwiching body Are connected to each other so as to be swingable around the swing axis,
As the cord support portion, a crimping piece that sandwiches and supports a cord that is inserted between the first sandwiching body and the second sandwiching body between the coupling portion and closer to the sandwiching end portion than the coupling portion. and it is formed from a pre-Symbol second Kyojitai protrudes the first clamping body side,
In the first connecting piece, a guide surface is formed at a position facing the extended end portion of the crimping piece, and the guide surface has a shape that guides the cord to the crimping piece with the sandwiching end portion opened. It is in the point formed in the position which adjoins the said crimping | compression-bonding piece in the closed state of a clamping end part .

With this configuration, when the cord is supported by the cord support portion, the clamping end portions of the first clamping body and the second clamping body are operated to the open side against the urging force of the urging member. Support is completed by inserting the cord between the first sandwiching body and the second sandwiching body and pushing the cord into the space between the crimping piece and the connecting portion. Further, the cord can be pushed into the space between the crimping piece and the connecting portion by inserting the cord between the first sandwiching body and the second sandwiching body and moving the cord along the guide surface. Thereafter, in a state where the clamping end portions of the first clamping body and the second clamping body have reached the closed state by the biasing force of the biasing member, the first sandwiching body and the second sandwiching body approach each other. Even if an external force acts in the direction in which the cord comes out from the portion, the cord can be prevented from coming out. That is, in the present invention, since the cord is sandwiched between the crimping piece and the connecting portion, the protruding amount of the crimping piece can be reduced as compared with the case where the cord is crimped only by the crimping piece. As a result, a cord clip that satisfactorily supports the cord while reducing the size of the crimping piece was rationally configured.

  In the present invention, the extended end portion of the crimping piece is protruded and molded in a posture toward the direction of the swinging shaft core in a posture parallel to the swinging shaft core in the connecting portion. A cord insertion / extraction opening may be formed between the two portions. According to this, even when an external force such as tension acts on the cord inserted from the cord insertion / extraction space, the cord is prevented from coming out by contact with the connecting portion.

In the present invention, the urging member is constituted by a torsion spring having a coil portion and a pair of leg portions, and a portion sandwiched between the pair of first connection pieces on the inner surface of the first sandwiching body, and the second A spring holding recess is formed on the inner surface of the holding body between the second connecting piece and a spring holding groove is formed on the inner surface of the first holding body and the inner surface of the second holding body.
