Description

DETAILED DESCRIPTION OF THE INVENTION <Technical Field of the Invention> The present invention relates to a case connecting mechanism for flexibly pivotally connecting two case bodies having a built-in magnetic field generator to each other.

<Background of the Invention> Generally, a hinge is used to flexibly connect two members, one piece of the hinge is screwed to one member, and the other piece of the hinge is similarly screwed to the other member. , Connect both members. In this case, when the member to be connected is a case body having a built-in magnetic field generator or the like, the work of connecting the case bodies is performed using a hinge after the magnetic field generator is incorporated into each case body and sealed.

However, in such an assembly structure, the assembly of the case body and the connection between the case bodies are performed in separate steps, so it takes time and labor for the assembly work, and there is a screw stop between the hinge and the case body. Since there are many of them, there is a problem that it takes time to connect them.

<Purpose of the Invention> The present invention has been made in view of the above-mentioned problems. The case body is assembled and the case body is constructed by forming a case body provided with a shaft body and a connector provided with a bearing portion into a divided structure. It is an object of the present invention to provide a novel case connecting mechanism that can realize the connection between them by the same work and can simplify the connecting work between case bodies.

<Structure and Effect of the Invention> In order to achieve the above-mentioned object, in the present invention, the connecting portion integrally formed on the side surface should be connected to a case body in which a pair of shaft bodies are integrally projected in opposite directions along the side surface. A case connecting mechanism is configured with a connecting tool including a pair of divided pieces each having a bearing portion into which each shaft of each case body is rotatably fitted.

The case body and the shaft body are formed by stacking the upper and lower case bodies and the semi-shaft portions formed on the side surfaces of the case bodies, and each of the case bodies to be connected to the bearing portions of the facing divided pieces. A shaft body is fitted and each divided piece is polymerized and fixed.

According to this invention, for the two case bodies to be connected,
Assembling the case bodies and connecting the case bodies by overlapping the upper and lower case bodies and the half shaft portions and fitting the upper and lower half shaft portions into the bearing portions of the respective split pieces to superpose and fix the respective split pieces. This can be realized all at once, the number of assembly steps and the time can be reduced, and the efficiency of the assembly work can be improved.

Also, by superposing and fixing a pair of divided pieces, the connection of both case bodies to this connector is completed at once.
Connection work between case bodies can be simplified.

Further, since the shaft body constituting the connecting mechanism is integrally formed with the case body, the practical effect is remarkable such that the case body can be firmly connected.

<Description of Embodiments> FIG. 1 shows a magnetic field generating treatment instrument to which a case connecting mechanism according to the present invention is applied.

The magnetic field generator shown in the figure has a magnetic field generator 2 in a case body 1.
A plurality of (shown in FIG. 2) accommodated and arranged are arranged in a vertical and horizontal arrangement, and adjacent case bodies 1 and 1 are pivotally connected to each other in a freely bendable manner.

As shown in FIGS. 2 and 3, each case body 1 is formed by butt-joining upper and lower case bodies 1A and 1B having a symmetrical shape, and a support wall is provided in a recess 10 in each case body 1A and 1B. 11, a magnetic field generator 2 is provided on the support wall 11.
Is fixed.

The magnetic field generator 2 in the illustrated example is an alternating magnetic field generator in which the coil 22 is wound around the iron core 21, but the present invention is not limited to this, and a DC magnetic field generator such as a permanent magnet can also be used. This magnetic field generator 2, when an alternating current is applied to the coil 22,
In the figure, it is formed so that an alternating magnetic field is generated in the vertical direction.
The magnetic field generators 2 and 2 of the case bodies 1 and 1 are connected to each other by a lead wire (not shown), and one of the case bodies 1 is connected.
A connection terminal is provided to connect the plug 31 of the power cord wire 3. In the figure, the notches 12 and 12 provided on the opening surface of the lower case 1B are for passing the lead wires.

Each case body 1 has a side surface on which the case body is located next to
The connection portion 4 is integrally formed, and the connection portions 4 and 4 of the adjacent case bodies 1 and 1 are pivotally connected to each other by the connection tool 5.

The connection portion 4 is formed by stacking the connection pieces 4A and 4B protruding from the upper and lower case bodies 1A and 1B, respectively,
When the half-shaft portions 42, 43 are projected on the connecting pieces 4A, 4B in the direction along the side surfaces of the case bodies 1A, 1B and the half-shaft portions 42, 43 of the upper and lower case bodies are overlapped with each other, the shaft body 44, 45 is formed.

The connection tool 5 has a vertically divided structure, and each divided piece 5
A and 5B are provided with overlapping surfaces 51 and 51 at both ends, and the shaft bodies 4 of the case bodies 1 and 1 connected to the overlapping surfaces 51 and 51, respectively.
Bearings 52 and 53 that rotatably support the bearings 4 and 45 are provided so as to face each other. Therefore, the one bearing portion 5 facing each other
The shaft body 4 of one case body 1 to be connected
4, 45 are fitted in the shaft members 44, 45 of the other case body 1 to be connected to the other bearing portions 52, 53, respectively, and the divided pieces 5A, 5B are stacked and screwed into the screw holes 54 (see FIG. By inserting (not shown) and screwing, the connecting tool 5 is formed, and the adjacent case bodies 1 and 1 are integrally connected by the connecting tool 5.

A mounting piece 6 for mounting a fixing member such as a belt to a human body is provided on the outer surface of the case body 1 located at the end of the plurality of case bodies. Also, although not shown,
A timer is connected to the power cord 3 so that the operating time of the treatment tool can be appropriately set according to the symptom.

Since the case bodies 1 and 1 are flexibly connected to each other, when they are applied to the surface of the body, the entire body can be deformed according to the surface shape of the body. Can be reliably fitted to the body surface. When the magnetic field generators 2 are simultaneously energized in this state, an alternating magnetic field is generated from all the case bodies 1 to the outside of the case, and acts widely and effectively on the affected area.
