Lock on xylophone case {APPARATUS FOR LOCK OF XYLOPHONE CASE}

The present invention relates to a xylophone case, and more particularly, to a xylophone case locking device that enables easy and quick rubbing and unlocking of a relatively small xylophone case used mainly by children.

In general, the xylophone case is composed of an upper and a lower case, and is rotated by a hinge, and the lower case is formed by being supported by a transverse transverse plate. In addition, a locking device having a locking part and a locking jaw is provided on the upper and lower cases so that the xylophone case does not open by itself in a closed state, and the xylophone in the case is opened and played through the locking device when playing.

However, the locking device of the xylophone case as described above releases the locking jaw from the fitting portion provided on the other side by pressing the locking portion provided on either one of the upper and lower cases with the finger inwardly. By opening the case to both sides, the xylophone is opened, which means that if the locking portion cannot be pressed with a predetermined force, it is impossible to detach the locking portion from the locking jaw, and thus the main user of the xylophone cannot apply a predetermined force to the finger. Children, etc. have a problem in that the xylophone case is not easy to unlock.

In addition, as a way to solve the problem of having to open the two gates on both sides after pressing the locking portion separated from the fitting portion, and to easily lock and unlock with one touch, the Republic of Korea Utility Model Registration No. 179264 (name: locking device) Known by

1 and 2 show one of such locking devices described in Korean Utility Model Registration No. 179264.

According to the Utility Model Registration No. 179264, a locking member 20 attached to one side of the front side of the xylophone upper case 10 and having a locking jaw 21 bent inwardly at one end thereof, and a lower case facing the locking member ( 10 ') and the locking member 30 having a ruled jaw 31 bent outwardly so that the engaging jaw 21 is hooked on one side, and the lower case 10' and the hinge to be seated on the upper portion of the locking member 30 The pressing piece 41 is installed on one side thereof, and the other side is composed of the unlocking member 40 in which the supporting pieces 42 are integrally formed.

The locking member 20 is integrally formed with the case on the front surface of the upper case 10 and has a locking jaw 21 having one end bent inward.

In addition, the locking member 30 is integrally formed with the case on the front surface of the lower case 10 'corresponding to the locking member 20, and has a ruled jaw 31 whose one end is bent outward.

In addition, the unlocking member 40 forms an inward stepped jaw 43 at an upper portion thereof, and forms a hinge hole 45 at an interface with an extension 44 vertically formed from the inward stepped jaw, the lower case 10. The hinge protrusions 11 formed at ') are fitted to each other, and have a pressing piece 41 mounted on one side of the extension part 44 and a supporting piece 42 integrally formed on the other side.

At this time, since the support piece 42 is for pushing the locking jaw 21 hooked on the ruler jaw 31 is formed to a size that can reach the locking jaw, so as not to interfere when the support piece pushes the locking jaw The scent end jaw 43 forms an intermediate portion shorter than the base piece.

In the conventional locking device configured as described above, as shown in FIG. 2A, when the upper case 10 and the lower case 10 ′ are pressed against each other, the locking step 21 of the locking member 20 is locked. The locking state is maintained by being fixed to the ruled jaw 31 of).

When the upper part of the unlocking member 40 is lifted by pressing the pressing piece 41 in such a state, the support piece 42 lifts the catching jaw 21 from the hanging jaw 31 at the same time as shown in FIG. 2B. do.

And when the pressing piece 41 is pressed so that one end of the unlocking member 40 abuts on the upper surface of the locking member 30, the supporting piece 42 is the upper portion of the locking jaw 21 is separated from the ruler jaw (31) 2c, the upper case 10 and the lower case 10 'is completely separated.

However, according to the locking device according to the above-mentioned Korean Utility Model Registration No. 179264, when the locking device is released, the supporting piece 42 of the unlocking member 40 is centered on the hinge by the pressing force of the pressing piece 41. It is unstable to lift the hook-shaped hooking jaw 21 which is held in close contact with the ruler jaw 31 while rotating, and is particularly caught when the support piece 42 which is in contact with the end of the hook-shaped hooking jaw rotates. When the jaw 21 is not lifted, a phenomenon sometimes occurs that is disengaged from the end of the locking jaw, which not only causes an error in unlocking the two cases but also suppresses the pressing piece again when an error of unlocking occurs. There is an inconvenience in using it to release it.

In addition, even if the locking jaw 21 of the unlocking member 40 is separated from the ruled jaw 31 by the support piece 42 and the lock is released, the support piece 42 makes the locking jaw 21 a sufficient distance. Since it is not configured to push outwards, children inevitably have to push their fingers against the upper surfaces of the two cases that are released and then open them to both sides.

Accordingly, an object of the present invention is to provide a lock of the xylophone case to release the xylophone case more easily and quickly when the user wants to use the xylophone case to open the two cases to both sides, the locking device is provided with a lock provided in the upper case The pressing piece is formed in contact with the elastic member on the bottom of the extending part of the release part, and a jungle extension jaw having a predetermined length is formed vertically downward at one corner of the extension part, and the pressing piece is pressed by pressing the unlocking part. Pressing the ruler member downward so that the ruler jaw of the ruler member is separated from the locking jaw of the locking member provided in the lower case and the jungle extension jaw to push the lower case outward relative to the upper case. .

The unlocking portion 102 is hinged to the hinge protrusion 111 of the upper case 100 so that the portion 105 is rotatably seated, and the pressing piece 106 protrudes from one side of the extension portion 105. In the locking device consisting of a), the contact piece 109a protruding in the longitudinal direction at regular intervals at the center of the upper surface of the ruler member 109, and the contact piece 109a of the ruler member 109 It is formed to be perpendicular to the bottom of one side of the extension portion 105 so as to extend according to the pressing of the pressing piece 106 The pressing piece 103 which presses the ruler member 109 downward by the rotation of the part 105 to release the ruler jaw 109b from the latching jaw 110a of the locking member 110, and the upper and lower parts. When the cases 100 and 101 are locked, they are formed to extend vertically downward at one end of the extension part 105 which is in contact with the lower case 101 to upper the lower case 101 according to the rotation of the extension part 105. The jungle extension jaw 104 having a predetermined length pushing outward with respect to the case 100 and the extension portion 105 are formed to be perpendicular to the bottom of the other side of the extension portion 105 with respect to the jungle extension jaw. When the upper and lower cases 100 and 101 are unlocked, the lower limit case 100 and the lower case 100 are configured of a rotation limit support rod 108 that suppresses the rotation of the extension part 105. Hinge which is formed on the interface with the vertical extension portion 105 to be fitted to the hinge projection 111 is fitted A.

In the above, it is preferable that the jungle extension jaw 104 is formed obliquely outward with respect to one end of the extension part 105.

The xylophone case lock according to the present invention made as described above will be described in more detail with reference to FIGS. 3 and 4.

Figure 4a is a longitudinal cross-sectional view showing a locked state of the xylophone case, the pressing jaw (110a) of the locking member 110 having elastic force when pressing the upper case 100 and the lower case 101 overlapping contact After passing over the ruled jaw 109b of the ash 109, the lock state is maintained by being engaged with each other.

In this way, the locking jaw 110a of the locking member 110 and the locking jaw 109b of the locking member 109 are engaged, and the lower case 100 and 101 are unlocked to use the xylophone in a locked state. By lightly pressing the pressing piece 106 of the extension part 105 formed in the part 102, the extension part 105 rotates counterclockwise around the hinge protrusion 111 of the upper case 100 and simultaneously pressurizes it. As the piece 103 pushes the contact piece 109a of the ruler member 109 downward, the ruler member 109 having an elastic force is inclined downward, as shown in FIG. 4B, whereby The upper jaw 109b of the government member 109 is separated from the locking jaw 110a of the locking member 110 so that the upper and lower cases 100 and 101 are locked.

In addition, the upper and lower cases 100 and 101 are unlocked by the rotation of the extension part 105 and are formed at one end of the extension part 105 so as to contact the lower case 101.
