EXAMPLE

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a front view of a state in which the door 20 is installed in front of the main body 10 of the electronic product equipped with the device of the present invention.

As shown in the figure, the lower end of the door fixing means 40 is provided.

FIG. 2 is a cross-sectional view taken along the line A-A 'of FIG. 1, and the upper end portion of the elastic wire 31 of the rectangular cross section is formed by the elastic return means 30 inside the frame 21 of the door 20. The configuration is coupled to the fixing ring 22 is fixed.

Therefore, when the door 20 is rotated, the support member 60 inserted into the receiving groove 71 of the fixed body 70 at the bottom thereof has a torsional stress when the door 20 is rotated in a fixed state. The door 20 is returned to the closing direction at the moment the elastic wire 31 has the elasticity to be returned and removes the force to twist and open.

At this time, the reason for drilling a plurality of screw holes 61 on the outer circumferential surface of the support member 60 is to be able to adjust the position where the screw is coupled to the fixing screw 72 to adjust the return force.

Meanwhile, as shown in FIG. 3, the hole 51 is drilled through the lower portion of the frame 21 so that the elastic wire 31 penetrates, and the locking jaw 52 is bent downward toward one side. Fixing piece 50 is fixed by the bolts 53 are installed.

The locking jaw 52 of the fixing piece 50 has a circular motion about its center when the door 20 is rotated while being fitted in the guide groove 73 of the fixing body 70.

Therefore, the guide groove 73 is formed in the fixed body 70 in consideration of the central arc.

On the other hand, the guide groove 73 of the fixed body 70 is formed so that the operating hole 74 is opened to the operating position of the intermittent piece 82, the stopper 75 protrudes to the position where the screw member 90 is installed. Molded.

The stopper 75 has a screw member 90 screwed toward the inside of the fixed body 70 as shown in FIGS. 5 and 6 to interrupt the operation position of the lock member 80. One side of the screw member 90 is provided with a spring 91 for elastically supporting the lock member 80.

The fixed body 70 is fixedly installed at a lower end of the electronic appliance main body 10 in a state in which the door 20 for rotating the support member 60 for supporting the elastic wire 31 is rotated.

According to the configuration of the present invention as such, the intermittent piece 82 is positioned to be lifted from the guide hole 73 in a state in which the end of the lock member 80 is pulled downward in the drawing and moved.

Therefore, it is caught when the fixing piece 50 fixed to the bottom of the door 20 is rotated together so that the locking jaw 52 which is inserted into the guide hole 73 of the fixing body 70 does not interfere with operation. The smooth opening and closing operation is made.

On the other hand, when the operator needs to fix the open state of the door 20 according to the user's needs or for maintenance, first, the lock member 80 is first opened in the fully opened state. As shown in FIG. 6, the artificial line is artificially moved from the virtual line to the position shown by the solid line.

Therefore, when the end of the intermittent piece 82 integrally bent at the distal end of the lock member 80 enters the passage of the guide hole 73, the door ( The locking jaw 52 of the fixing piece 50 which has been rotated together with 20) is prevented from being closed by being caught by the intermittent piece 82 of the lock member 80.

When the door 20 is normally closed again, the lock is released by simply pulling the lock member 80 to a position as shown by the virtual line of FIG.

Such locking member 80 may be operated by hand, but is located at the lower end of the main body 10 of the electronics and the door 20, and thus can be easily operated by foot.

The stopper 75 determines its position so as not to pass the rotation range of the lock member 80.

On the other hand, the screw member 90 is installed so that the lock member 80 maintains its position so as not to flow in the locked state and the released state of the door 20.

That is, the screw member 900 is screwed to the fixing body 70 by passing through the assembly hole 81 having a larger diameter than the screw member 90 to the lock member 80 in the position of the stopper 75, the lock member Since the edge portion around the assembly hole 81 of the 80 is not caught by the screw thread of the screw member 90, the door 20 is maintained in the locked state and the rotationally released state when the door 20 is positioned in the locked state and the freely rotatable state. .

Then, the user can switch the position of the lock member 80 by applying a slight force.

[Effect of design]

As described above, according to the present invention, there is no need to limit the door opening angle of the electronic product in a normal use state.

The door 20 can be kept open by simply operating the lock member at a desired time by the user, and the release operation for returning is easy.

Therefore, the user can be convenient and the reliability of the product is improved.

Moreover, the structure is simpler and it is a very useful design, such as giving economic profit by lowering cost.
