Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a curl cord holder for easily holding a curl cord in a device having a retractable cord (curl cord) wound spirally.
[0002]
[Prior art]
For cordless devices such as electric or electromagnetic or electronic processing tools, handsets, sensors, etc. (hereinafter referred to as sensors, etc.) that are manually operated by humans and connected to the main body of the device by a cord or a desk phone Curled (curled) to make it stretchable, keep the cord short when the sensor is not in use so that it does not get in the way, and when using the sensor, the cord can easily stretch and move the sensor Can be expanded. When such a curled cord is left in a suspended state, the curled portion gradually expands, which makes the handling inconvenient and causes the problem that the handling becomes difficult because it is entangled with an object.
[0003]
In order to prevent such problems, there are attempts to store the cord in the device body or temporarily fix it to the device by mechanical means, but it requires extra space and is also required to release the lock. It takes time and effort. In particular, devices that require the operating source to be moved to the required position instantly by hand, such as a defibrillator, require the cord to be unlocked urgently. However, the conventional mechanical cord holding mechanism hinders the emergency unlocking of the cord. It cannot be adopted.
[0004]
[Problems to be solved by the invention]
The curl cord has a weight as compared with a general cord of the same length, and is easily loosened by hanging from the device. It is necessary to fix the curl cord in order to prevent it from being loosened or deformed. A large space is required to be housed in the device main body or mechanically fixed. In particular, in the case of a defibrillator or the like, the fixing of the cord is urgent. Therefore, there is a demand for a structure sawing means that can be easily detached by pulling by hand without imposing a burden on the cord and without mechanical operation.
[0005]
An object of the present invention is to provide a curl cord holder having a simple structure that does not require an extra space and is extremely easy to fix and unlock.
[0006]
[Means for Solving the Problems]
The present invention has been made to solve the above-mentioned problems, and is a curl cord holder characterized by taking the following technical means. That is, the present invention is a curl cord holder comprising an upright wall provided on the outer surface of a device having a curl cord and forming a plurality of rows of grooves into which each line of the curl portion of the curl cord is fitted and locked. is there. Here, the curl cord is an electric or communication cord in which a conductor is coated, and refers to an electric cord that is formed to be stretchable by spirally winding it. The curl cord holder of the present invention is provided integrally with the device on the outer surface of the device.
[0007]
The groove is a straight groove having a width and a depth equivalent to the diameter of the cord of the curled cord and an inclination angle substantially equal to the lead angle of the spiral of the curled cord. The groove width should be approximately the same as the cord diameter, preferably slightly smaller, and the groove pitch should be slightly larger than the cord spiral pitch, with a tilt angle approximately equal to the curl cord spiral lead angle. By forming a straight groove, when the cord is lightly pushed into the groove, the cord is elastically deformed to be fitted and locked in the groove, and is held as it is. That is, since an appropriate holding force acts between the side walls of the groove using the axial tensile force, compressive force, and twist caused by the curl of the curl cord, the curl cord can be stably fixed and held. This holding state can be easily released by pulling the curl cord by hand.
[0008]
The upright wall body may be a separate molded product attached with an adhesive or the like, but is preferably an integrally molded body made of the same material as the device main body.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. FIG. 4 shows a plan view of a defibrillator 50 showing an example to which the present invention is applied. The defibrillator 50 is a device that removes ventricular fibrillation of the human heart. The ventricle, which is a collection of muscles, contracts and relaxes by the stimulation signal from the sinus node and pulsates, but if each myocardium moves apart for some reason, blood cannot be pumped out. This state is called ventricular fibrillation. The defibrillator temporarily contracts the myocardium of the ventricle by passing a large current through the paddle through the ventricle in which fibrillation has occurred, aligns the rhythm, and restores the original beat. Therefore, emergency operability is extremely important for a defibrillator. In the defibrillator 50 shown in FIG. 4, two manual paddles 61 (only one is shown) are connected by a device body 51 and a curl cord 62. The paddle 61 is provided with an extracorporeal electrode plate on the back surface of the figure and a grip handle 63 on the top surface. In use, an external electrode plate is pressed against the chest wall of the patient to give a shock. The paddle 61 is stored in the paddle storage portion 64 when not in use.
[0010]
The device main body 51 of the defibrillator 50 is portable, has a transport handle 52, and is brought in an emergency to give a piece to be treated. The required value is set with the setting button 53 on the operation panel, the energy setting knob 54 is set, and the paddle 61 is pressed against the chest of the patient. The display 55 displays time, battery status, paddle status, energization status message, ECG waveform, alarm mark, heart rate, output energy value, and the like. In the recording unit 56, the process progress is recorded. Other necessary power connectors, antennas, ECG output connectors, speakers, etc. are mounted.
[0011]
There are two paddles 61 connected to the output connector via the curl cord 62. The curl cord 62 is kept short when the paddle 61 is not used, and when the paddle 61 is used, the curl cord 62 can be extended and contracted so as to reach a required portion, and is curled in a spiral shape. Since the defibrillator 50 requires urgent use, the curl cord 62 should not be entangled with other things and the extension / contraction operation should not be restricted. Therefore, when the paddle 61 is not used, the curl cord 62 is compactly stored along the main body so that it does not get in the way. Is requested.
[0012]
FIG. 3 is a side view of the defibrillator 50 and shows an embodiment of the curl cord holder 10 according to the present invention. 1 is a partially enlarged view of a portion of the curl cord holder of FIG. 3, and FIG. 2 is a cross-sectional view taken along arrow AA of FIG. FIGS. 1 to 3 also show a part of the curl cord 62 that is locked to the curl cord holder.
[0013]
The curl cord holder 10 of the embodiment is formed on the side surface of the main body 51 of the defibrillator 50. The position where the curl cord holder 10 is formed should be a portion that does not get in the way on the outer surface of the device near the curl cord 62, for example, a side wall. It may be the top surface. The curl cord holder 10 of the embodiment shown in FIG. 3 is integrally formed on the side wall of the main body 51 of the defibrillator 50 by injection molding. In FIG. 4, the reference numeral 10 is turned down, but it is hidden behind the upper surface of the main body and cannot be seen. The curl holder 10 is integrally formed of the same material as the main body 51 using ABS resin. Of course, other materials, for example, molded products made of other plastics, metals, non-metallic materials, etc. may be attached to the side wall with an adhesive or the like, but as described above, If this is the case, it is most suitable because it does not require labor in terms of manufacturing, molding, and integrated mounting. It should be noted that the material and shape need not be damaged by the cord, while the curl cord holder itself has a high strength against damage and a high durability.
[0014]
As shown in FIGS. 1 and 2, the curl cord holder 10 has a groove 11 having a groove width and a depth sufficient to allow each line of the curl cord 62 to enter lightly and to be easily detached, as shown in FIGS. A thin upright wall 12 that forms the side wall of the groove 11 is erected. The width of the groove 11 is, for example, 0.1 to 0.3 mm narrower than the diameter of the curl cord 62. The groove 11 is a straight groove having an inclination angle α substantially equal to the lead angle of the spiral of the curl cord.
[0015]
FIG. 2 shows the upright wall 12 molded integrally with the wall 57 of the body 51 of the defibrillator 50. The thickness of the upright wall 12 is made as thin as possible within a range having sufficient durability. For example, it is set to 1 to 1.5 mm. The top of the upright wall 12 has a semicircular cross section, and an appropriate radius (corner roundness) is given to the base. Moreover, it is good to provide the appropriate reinforcement rib 13 which connects the upright wall bodies 12 mutually. The longitudinal dimension of the groove 11 is preferably larger than the curl diameter of the curl cord 62.
[0016]
As shown in FIG. 4, when the curl cord 62 is lightly pressed by hand in the direction of the arrow 65, the curl cord 62 is fitted and locked in the curl cord holder 10 as shown in FIGS. The When the paddle 61 is moved by hand during use of the paddle 61, the curl cord 62 is automatically released from the fixed state.
[0017]
【The invention's effect】
Since the curl cord holder of the present invention is configured as described above, it does not require a special space for providing a storage portion or mechanically fixing the device body, and without burdening the curl cord. Fixing and unlocking can be performed very easily and reliably. In addition, the injection molded product can be formed integrally with the main body, and the cost can be reduced.
