DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curl cord holder for easily holding a curl cord in a device provided with an elastic cord (curl cord) wound spirally.

[0002]

2. Description of the Related Art Electric or electromagnetic or electronic processing tools, handsets, sensors, and the like (hereinafter referred to as sensors), which are manually operated by humans, are combined with a main body of a device by a cord or a desk phone. The cord is given a spiral curl (winding habit) so that it can be expanded and contracted. When the sensor is not used, the cord is kept short so that it does not get in the way, and when the sensor is used, the cord can be easily extended. The moving range of the sensor and the like can be expanded.
If such a curled cord is kept in a hanging state, the curled portion gradually expands, which causes inconvenience in handling, and causes a problem that handling becomes difficult, such as being entangled with an object.

[0003] In order to prevent such a problem, attempts have been made to store the cord in the main body of the device or to temporarily fix the cord to the device by mechanical means. However, extra space is required and the fixing is released. It takes time to do it. Emergency release of the cord is required especially for devices that require the instantaneous movement of the operation source to the required position by hand, such as a defibrillator, but the conventional mechanical cord holding mechanism hinders the emergency release of the cord. And cannot be adopted.

[0004]

Curled cords are heavier than general cords of the same length, and are easily loosened by hanging from equipment. In order to prevent the curl cord from becoming loose or deformed, it is necessary to fix the curl cord. A large space is required to be stored in the apparatus main body or mechanically fixed, and in particular, in the case of a defibrillator or the like, it is urgent to release the fixing of the cord. Therefore, there is a need for a structural sawing means that can be easily removed by hand pulling without burdening the cord and without mechanical operation.

An object of the present invention is to provide a curl cord holder having a simple structure which does not require an extra space, is extremely easy to fix and release, and does not require any extra space. It is.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and is a curl cord holder characterized by employing the following technical means. That is, the present invention provides a curl cord holder characterized in that the curl cord holder is provided on an outer surface of a device having a curl cord and comprises an upright wall that forms a plurality of rows of grooves into which the respective lines of the curl portion of the curl cord fit and lock. is there. Here, the curl code is an electric or communication code in which a conductor is coated,
It refers to an electric cord that has a spiral winding and is formed to be stretchable. The curl cord holder of the present invention is provided integrally with the device on the outer surface of the device.

It is preferable that the groove has a width and a depth equivalent to the diameter of the cord of the curled cord, and is a straight groove having an inclination angle substantially equal to the lead angle of the spiral of the curled cord. The width of the groove should be approximately equal to the diameter of the cord, and preferably slightly smaller.The pitch of the groove should be slightly larger than the pitch of the spiral of the cord, and has an inclination angle approximately equal to the lead angle of the spiral of the curled cord. With the straight groove, when the cord is lightly pushed into the groove, the cord is elastically deformed, fitted and locked in the groove, and held as it is. That is, since an appropriate holding force acts between the side walls of the groove by utilizing the tensile force, the compressive force, and the torsion in the axial direction due to the curl of the curl cord, the curl cord can be stably fixed and held. This holding state can be easily released by manually pulling the curl cord.

The upright wall may be formed by attaching a separate molded product with an adhesive or the like, but it is preferable that the upright wall be an integrally molded product of the same material as the main body of the device.

The defibrillator 50 is a device for removing ventricular fibrillation of a human heart. The ventricle, which is a collection of muscles, contracts and relaxes and beats due to a stimulus signal from the sinus node, but if any of the myocardium moves apart for some reason, it cannot pump blood. This condition is called ventricular fibrillation. A defibrillator is a device that once contracts the myocardium of the ventricle by passing a large electric current through a paddle through the ventricle in which the fibrillation has occurred, adjusts the rhythm, and restores the original beat. Therefore, emergency operability of a defibrillator is extremely important. The defibrillator 50 shown in FIG.
