Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a hinge, and its gist is that one hinge part 20 is provided with a pair of bearing parts 25, 25 facing each other, and the other hinge part 21 is provided with a shaft mounting part 24. is provided, the pivot shaft 23 is passed through the shaft attachment part 24, the pivot shaft is made to protrude from both ends of the shaft attachment part 24, and the pivot shaft 23 is caulked and fixed to the shaft attachment part 24,
A spring material 22 such as a coil spring is inserted into the protruding shaft portion protruding from one end side of the shaft mounting portion 24, and the pivot shaft 23 is pulled into the pair of bearing portions 25, 25 against the spring material 22. The hinge is characterized by being inserted through the hinge to pivotally support the shaft mounting part 24 and the bearing parts 25, 25, and its purpose is to ensure that the external dimensions are accurate and that the pivot shaft is To provide a hinge that does not protrude, has small dimensions, is easy to assemble and disassemble, and does not allow a pivot shaft to come off even when turned upside down.

In the conventional hinge 18, as shown in FIG.
Since both ends of 30 were crushed and caulked, this caulked part had to protrude in the row of hinges 18, and the hinge 18
The disadvantage was that it became large.

Further, since both ends of the pivot shaft 230 are caulked with poor precision, there is also a drawback that the external dimensions of the hinge 18 are deteriorated.

Furthermore, as shown in Japanese Utility Model Publication No. 43-23473, it has been proposed to prevent the pivot shaft from slipping out by using a pivot shaft with a square head to prevent the pivot shaft from rotating. However, in such a configuration, there is a problem in that the hinge can only be used in a specific manner in which the square head of the pivot shaft faces upward.

The present invention was made in view of such problems,
Hereinafter, a case where the present invention is applied to a mirror cabinet A will be explained as an example.

As shown in Figures 1 to 3, the mirror cabinet main body 1 has a mirror surface part 9 in the upper half of the K, and there are small storage areas 10 on both sides of the mirror part 9, and below the storage area 10 on the right side of the figure there are switches and other parts. There is a power source section 11 equipped with an outlet etc., and a wash basin section 14 in the lower half is provided with a wash bowl 12.
An opening/closing door 13 is hinged to the front surface of the washbasin section 14.

At the upper end of the mirror cabinet body 1, an illumination light storage section 2 with a downward opening projects toward the front side.

A lighting fixture body 15 is disposed on the back side of the illumination lamp storage section 2, and an illumination lamp 3, such as a straight tube fluorescent lamp, is disposed on the front side thereof.

(Other than this may of course be used.) As shown in FIG. The side frames of the cover frame 5 are respectively pivotally supported.Here, using the distance e from the screw 16 to the tip of the cover frame 5, the distance l from the screw 16 to the rear end of the cover frame 5 is expressed as <1. Since ~, the cover frame 5 has a weight i. c and rotates to the 1,000-iij side.

In addition, a sliding groove 17 is provided on the inner surface of the side edge of the first cover frame 5.
is recessed, and the front anchor of the cover frame 5 is open.
I L- Keep the light passing through 7 in and out 1] 8,)
This temporary 7 is a transparent or translucent, colorless or colorless glass plate or plastic plate, which is fitted into the cover frame 5 and dusted, so that both ends thereof can freely slide into the sliding grooves 17 of the cover frame 5. I'm stuck in it.

Further, a locking tool 6 is vertically installed at the tip of the illumination light storage section 2 of 1-, and the locking tool 6 is pivotally connected to the illumination light storage section 2 with a hinge 18. It seems to rotate with the ten end as the fulcrum.

In addition, the 1 end of this 1st eye L6 has a contact portion 29 protruding, and the lower part has a 1 end portion 19 protruding toward the rear 5, and the cover frame 5. The tip is moored a).

Next, a detailed description will be given of the hinge 18 to which the engagement tool 6 is hinged.

One piece of the hinge 1801 is the hinge part 20 on the bearing side, and the other is the hinge part 21 on the pivot shaft side, and the hinge part 20 on the bearing side and the hinge part 21 on the pivot shaft. It is composed of material 22,
The pivot 23 is caulked and fixed to the barb attachment part 24 of the hinge part 21 on the pivot shaft side.

As shown in FIG.
A unique bearing part 2 in which the lever material 22 is compressed and the pivot shaft 23 is pulled out, and the A7 type has the advantage of the butterfly A part 20 on the bearing side.
5. Pivotally attached to 25.

This spring material 22 is connected to the bearing part 25 on the right side.
24, and the spring 22 extends, and its elastic force pushes the right side of the single shaft receiving part 24 in the figure into the bearing part 25 of the left side. The pivot support 23 can be installed without any play in the axial direction.

Therefore, with this hinge 18, it is difficult to remove it from the hinge 18. ．．
F. As shown in FIG. 4, such a hinge 18 has a hinge part 20 attached to the upper surface of the illumination lamp storage part 2, and the hinge 18 is attached to the upper surface of the illumination lamp storage part 2, and The hinge part 21 of the eye 1 is fixed to the back of the locking tool 6, and the locking tool 6 is kept hanging in the shape of the eaves by the spring force of the spring material 22. There is.

When the lighting lamp 3 is turned on to use the mirror cabinet A, the circle passes through the ventilation plate 7 and illuminates the front of the mirror cabinet A.

Next, the case of replacing the burnt-out illumination lamp 3 with another illumination lamp 3 will be explained with reference to FIG.

When the locking tool 6 is rotated upward (clockwise) against the spring force, the tip of the cover frame 5 is deflected from the locking protrusion 19, and the tip rotates downward (counterclockwise) under its own weight. At this time, the contact part 29 of the tool is in contact with the hinge 18 and is in a water state.
It does not rotate when turned to L.

Further, the rear end of the cover frame 5 comes into contact with a slit/flange 28 provided on the inner surface of the illumination lamp housing section 2 and stops.

Then, pull out the regular plate I from the entrance 8 at the tip of the force bar frame 5.

Next, pass through the cover frame 5 and insert your hand into the illumination lamp storage section 2, remove the burnt-out illumination lamp 3, and remove it from the illumination lamp storage section 29'+r-.
, bring it up.

Next, after attaching a new lighting lamp 3 to the main body 15 of the illuminator j-↓, insert the light passing plate 1 into the cover frame 5 through the access/exit 1-]8, then lift the tip of the force bar frame 5 and attach it to the fixture. Since the present invention has a structure as shown in Fig. 6, the pivot +tQI+ is 4 crucian protrusions -t= ] either dark b or the bearing part -. 《There is no need to swage both ends of the pivot shaft protruding from the hinge as in the conventional example, and there is no need to make both ends of the pivot shaft protrude outward. Therefore, the hinge's external shape can be made smaller, and since it is not necessary to caulk both ends of the pivot shaft, the external shape of the hinge can be made higher.

In addition, especially in the present invention, a spring material such as a coil spring is inserted into the protruding shaft portion of the shaft mounting portion that protrudes from the Lid side, and the support J-shaft is mounted in a single-benefit bearing against the spring material. It is inserted into the shaft mounting part and the bearing part in a circular manner to pivot the [shaft A] part and the bearing part. Therefore, it is easy to disassemble the hinge holder, and since the hinge that is erected in the gendon style is energized by a spring material such as a coil spring, the pivot spider 1 does not fall apart. Therefore, even if the hinge is turned upside down, the pivot shaft will not come off, and there is an advantage that the hinge can have no directionality.
