In the embodiment of the present invention, a state in which the locking plate 5 is tilted by about 15 degrees from the vertical state in contact with the opening 6f toward the release position is defined as the locking position. This is to enhance the locking force of the square core 7 as described later.

FIG. 3A is an external view of the locking plate 5 according to the present invention, and FIG. 3B is a sectional view thereof. Locking plate 5
Has a square hole 5a in the center of the disc through which the square core 7 passes,
The upper and lower sides of the square hole 5a form an upper locking blade 5b and a lower locking blade 5c which have a predetermined inclination angle and are parallel and opposed to each other. The upper tongue 5 is located above and below the locking plate 5.
d and a lower tongue 5e are provided, and the lower tongue 5e is slightly longer than the upper tongue 5d. This locking plate 5
As shown in FIG. 3B, the oblique projection width d2 based on the inclination angle of the upper and lower locking blades 5b and 5c is formed to be larger than the orthographic projection width d1 of the square hole 5a. That is, when the square core 7 is penetrated through the locking plate 5, the maximum dimension between the surfaces of the square core 7 in which the locking grooves 7 a are cut is made substantially equal to the inclined projection width d 2, and the orthogonal projection width d 1 is It is formed so as to be smaller than the inclined projection width d2.

The locking plate 5 is formed by punching an outer shape and a square hole 5a in a metal plate by pressing, and forming upper and lower locking blades 5b and 5c.
The part is formed by bending.

The locking plate 5 is not limited to such a manufacturing method.
It can also be manufactured by shaving a thick metal plate. FIG.
(C) and (d) show such a locking plate 51, which is similar to the above-described locking plate 5 by shaving off the square holes 5 a with respect to the surface of the locking plate 51. Further, the oblique projection width d2 due to the inclination angle of the upper and lower locking blades 5b and 5c is formed to be larger than the orthographic projection width d1 of the square hole 5a.

The locking plate 5 can also be manufactured by press drawing. FIGS. 3 (e) and 3 (f) show such a locking plate 52.
The upper and lower locking blades 5b and 5c are simultaneously drawn at the time of pressing. This locking plate 52 is also a locking plate 5
Similarly to the above, the oblique projection width d2 due to the inclination angle of the upper and lower locking blades 5b and 5c is made larger than the orthographic projection width d1 of the square hole 5a.

It is to be noted that the locking plate 5 can be manufactured by using a working method such as forging, casting, die casting or the like in addition to press working or shaving work, and furthermore, a working method by sintering can be applied. .

When the locking plate 5 is manufactured by die-casting or sintering, a shape in which the thickness of the locking blades 5b and 5c is increased like the locking plate 53 shown in a sectional view in FIG. And the rigidity of the locking blades 5b, 5c is increased. FIG. 4 (b)
A structure in which steps are provided above and below the square hole 5a as in the locking plate 54 shown in a sectional view in FIG. In the configuration of the locking plate 54, if a step corresponding to the opening 6f of the locking unit 6 is provided, it can be held in a substantially vertical locking posture.

Next, the operation principle of locking the square core 7 by the door handle 1 according to the present invention will be described with reference to FIGS.

Even if the square core 7 is inserted into the through-hole 6c of the locking unit, the locking plate 5 is held by the urging force of the spring 4 until the square core 7 comes into contact with the locking plate 5. Opening 6
f and keeps the locking posture.

As the insertion of the square core 7 proceeds, as shown in FIG. 5 (a), the tip of the square core 7 is connected to the upper and lower locking blades 5b and 5b of the locking plate 5.
5c, the insertion force overcomes the biasing force of the spring 4, and the locking plate 5 is biased toward the spring 4. At this time, the upper tongue 5d of the locking plate 5 is restricted and held by the engagement groove 3a, but the lower tongue 5e rotates in the operation opening 2b, and the inclined plate 5 starts to incline toward the release posture. As a result, the width of the square hole 5a of the locking plate 5 with respect to the square core 7 approaches the inclined projection width d2, so that the locking is released and the square core 7 advances inside the square hole 5a.

When the insertion force of the square core 7 is released, FIG.
As shown in (b) and (c), the locking plate 5 starts to return to the locking position due to the urging force of the spring 4, and the width of the square hole 5 with respect to the square core 7 decreases toward the locking position. It approaches the orthogonal projection width d1. As a result, the upper locking blade 5b is
a and the upper and lower locking blades 5b, 5b of the locking plate 5
Hold the square core 7 with c. Then, the locking plate 5 locks the square core 7 in a substantially vertical locking posture inclined about 15 degrees with respect to the square core 7. At the same time, the locking plate 5 has the upper tongue 5d having the opening 6f.
Therefore, the square core 7 is integrally fixed to the boss 2. In the present embodiment, a margin of about 15 degrees is provided between the vertical state in which the lower tongue piece 5e of the locking plate 5 contacts the opening 6f and the locking posture. This is because, when a force for pulling out the square core 7 is applied in the locking posture, the holding and engagement of the square core 7 by the locking plate 5 are further promoted, and the locking force is further strengthened.

As described above, if the insertion force is applied to the square core 7 toward the boss 2, the square core 7 can be easily inserted, and if the insertion force is released, the square core 7 is locked inside the boss 2 and comes off. Disappears.

As shown in FIG. 6, a tool such as a screwdriver is applied to the operation opening 2b provided on the back side of the boss portion 2 to move the lower tongue 5c of the locking plate 5 to the release position. Then, the width of the square hole 5a of the locking plate 5 with respect to the square core 7 approaches the inclined projection width d2 and widens, and the locking plate 5 releases the locking of the square core 7, so that the square core 7 can be pulled out. it can.

FIG. 7 shows a connection procedure using the door handle 1 according to the embodiment of the present invention described above. The lock case 20 is attached to the attachment hole 31 of the door 30 in advance, and the door handle 10 is attached to the door handle 10. , One end of the square core 7 is inserted and attached and fixed with the screw 10a.

Then, through the opening 32 opened in the door 30 and the drive hole 21 of the lock case 20, the door handle 10
The door handle 1 is inserted into the penetrated square core 7 and the door handles 1 and 10 are inserted when the gap between the doors becomes appropriate. Release the force. Then, since the square core 7 is locked by the door handle 1, the door handle 1 and the square core 7 are integrally fixed, and the mounting is completed.

If the door handle 1 is inserted too much, as described above, the square core 7 is moved from the boss 2 by operating the locking plate 5 of the operation opening 2b provided at the lower part of the boss 2. Since it comes out, it can be inserted again.

In the above embodiment of the present invention, the upper locking blade 5b and the lower locking blade 5c are provided in the square hole 5a of the locking plate 5, but the lower locking blade 5c is Since the function of pinching the square core 7 together with the stop blade is performed, the square core 7 can be locked even with a configuration in which only the upper locking blade 5b is provided. Although the upper and lower locking blades 5b and 5c are provided on the sides of the square hole 5a, they can be formed in various ways, for example, by providing a protruding locking blade on a part of the side.

In the above-described embodiment of the present invention, the engaging grooves 7a are formed on the upper and lower surfaces of the square core 7. However, when the square core 7 is made of a relatively soft material, Even when the stop groove 7a is not provided, the upper and lower locking blades 5b of the locking plate 5,
5c can be sufficiently locked.

Although the locking unit 6 is inserted into the locking portion 3 inside the boss 2, the spring 4 and the locking plate 5 are directly connected to the locking portion 3 instead of such a configuration. May be provided.
