Description

The present invention relates to a music box box suitable for use as a teaching material for elementary school drawing work or as a souvenir for graduation work, for example.

There is a music box used as a souvenir for elementary school drawing work and graduation work. The music box box used for this music box is a type that colors the box of the finished product, a type that assembles the box of the semi-finished product and then colors it, or a kit type music box that forms the box by combining material parts. and so on.

A general music box box mainly uses a hinge as a metal fitting for connecting the lid and the box (Patent Document 1). However, in the music box box used for teaching materials, a hinge is not used for the connecting metal fitting, but a rotating rod attached to the lid is often used (Patent Document 2).

That is, in order to fix the hinge, it is necessary to fix it to the box body side and the lid body side with a plurality of wood screws, respectively, and the screwing work at these multiple places is not suitable for elementary school students. Therefore, in music box boxes used for teaching materials, rotating shaft rods are often used instead of hinges.

This rotating shaft rod is a support member fixed to the lid body, and the lid body can be opened and closed by screwing both ends of the rotating shaft rod to the box body with pivot screws. That is, the connecting work of the lid body is the work of screwing both ends of the rotary shaft rod with a pair of pivot screws penetrating both sides of the box body.

On the other hand, there are rotating pins used for furniture doors and the like. For example, there is a pivot pin for a rotating door described in Patent Document 3. This pivot pin has a configuration in which a pin body is freely retracted and retracted together with a coil spring in a tubular case, and a pin body protruding from the case is pivotally supported.

When such a rotating pin is used for a music box box, screwing work such as a hinge or a rotating shaft rod is eliminated. That is, the connection work of the lid body is completed by fitting the case of the rotating pin into the insertion holes provided at both ends of the lid body and inserting the pin body of the rotating pin into the support holes formed in the box body.

However, when using a rotating shaft rod attached to the lid, even if the number of screwing points is smaller than that of a hinge, screwing work using a tool such as a screwdriver is used when screwing the pivot screw. Remains. For elementary school students, screwing work using tools tends to be difficult, and a means for connecting lids without using tools such as a screwdriver has been desired.

On the other hand, by using the rotating pin for the music box box, it becomes possible to connect the lid without using a tool such as a screwdriver. However, for elementary school students, there is a difficult task in a part of the process of connecting the tip of the rotating pin to the box body.

That is, in order to insert the pin body protruding from the tip of the rotating pin into the support hole of the box body, slide the pin body to the position of the support hole while forcibly pushing the pin body into the inside of the tubular case. When the pin body is moved and the pin body is opened at the position of the support hole, the pin body is housed in the support hole by the restoring force of the coil spring.

Therefore, for elementary school students, the process of sliding the pin body to the position of the support hole while pushing it into the tubular case is expected to use a tool for pushing the pin body into the tubular case. It tends to be a difficult task. In this way, the use of the rotating pin eliminates the use of the driver, but it may be a difficult task when sliding the pin body.

As described above, the music box box used as a teaching material for elementary school drawing work and as a souvenir for graduation work has been desired to have a structure that simplifies the work of connecting the lid to the box.

Therefore, the present invention was devised to solve the above-mentioned problems, and the work of connecting the lid of the music box box to the box becomes extremely easy, and it is used as a teaching material for elementary school or as a souvenir for graduation work. The purpose is to provide a music box box suitable for the above.

In order to achieve the above object, the first means in the present invention is provided at the box body P of the music box, the lid body Q swinging at the opening of the box body P, and the swinging end portion of the lid body Q. In a music box box provided with a rotating pin R, the tip portion of the rotating pin R is housed in a support hole P1 formed in a fulcrum portion of the box body P and the lid Q is connected, from the vicinity of the opening of the support hole P1. An introduction inclined surface P2 to which the tip of the rotating pin R hits is formed toward the opening of the box body P, and the tip of the rotating pin R is slid from the box body P opening side of the introduction inclined surface P2 to the support hole P1 side. It is configured to be introduced into the support hole P1.

The second means is to form a tapered surface R4 at the tip of the rotating pin R, and to form the box body P from the inside of the support hole P1 in the vicinity of the tapered surface R4 of the rotating pin R housed inside the support hole P1. An exit surface portion P2a is formed which is inclined upward to hit the tapered surface R4 of the rotating pin R, and the tapered surface R4 of the rotating pin R is exposed to the opening of the box body P from the support hole P1 side of the exit surface portion P2a. The rotating pin R is configured to be taken out from the support hole P1 by sliding in the direction.

The third means is to form a tapered surface R4 at the tip of the rotating pin R, and to form the box body P from the inside of the support hole P1 in the vicinity of the tapered surface R4 of the rotating pin R housed inside the support hole P1. A rear inclined surface P3 to which the tapered surface R4 of the rotating pin R hits is formed toward the rear side, and the tapered surface R4 of the rotating pin R is moved from the support hole P1 side of the rear inclined surface P3 to the rear side of the box body P. It is configured to slide and take out the rotating pin R from the inside of the support hole P1.

The rotating pin R of the fourth means is attached to the tubular case R1 housed in the insertion hole Q1 of the lid body Q, the coil spring R2 housed in the tubular case R1, and the tip end side of the coil spring R2. It is assumed that the pin body R3 formed so as to appear and disappear from the tubular case R1 is provided.

The rotating pin R of the fifth means is provided at the insertion body 10 housed in the insertion hole Q1 of the lid body Q, the push spring 20 provided in the insertion body 10, and the tip end portion of the push spring 20. The pin body 30 and the pin body 30 are integrally molded with a synthetic resin material.

The music box box of the present invention is configured so that the tip portion of the rotation pin R is slid on the inclined surface P2 for mounting the pin and the tip portion of the rotation pin R is introduced into the support hole P1. The work of connecting the body Q becomes extremely easy. As a result, we were able to provide a music box box suitable for use as a teaching material for elementary school students' drawing work and as a souvenir for their graduation work.

Moreover, since the exit surface portion P2a that is inclined from the inside of the support hole P1 toward the upper side of the box body P and is in contact with the tapered surface R4 of the rotation pin R is formed, the rotation inside the support hole P1 is performed along the exit surface portion P2a. The pin R can be taken out.

Further, a rear inclined surface P3 for taking out the pin is formed from the inside of the support hole P1 of the box body P toward the rear side of the box body P, and the tip portion of the rotating pin R is slid to the rear inclined surface P3 for removing the pin. Since the tip portion of the rotary pin R is configured to be removed from the support hole P1, the work of removing the lid Q connected to the box body P can be easily performed. Therefore, even after the lid Q is connected to the box P, the lid Q can be removed and arbitrarily modified, and it can be optimally used as a teaching material for drawing work.

Further, the rotation pin R is attached to the tubular case R1 housed in the insertion hole Q1 of the lid body Q, the coil spring R2 housed in the tubular case R1, and the tip side of the coil spring R2 from the tubular case R1. Since the structure includes a pin body R3 formed so as to appear and disappear, a conventional rotating pin R can be used. Moreover, by forming the tapered surface R4 at the tip of the pin body R3 protruding from the tubular case R1 of the rotating pin R, the work of attaching and detaching the lid body Q can be further facilitated.

Further, as the rotating pin R, an insertion body 10 to be housed in the insertion hole Q1 of the lid body Q, a push spring 20 provided in the insertion body 10, and a pin body 30 provided at the tip of the push spring 20. By using a rotating pin R integrally molded with a synthetic resin material, it is possible to provide the product at low cost. Moreover, since the rotating pin R of the synthetic resin has water resistance, there is no risk of rusting even if paint such as paint adheres to it. Therefore, for example, it is most suitable for applying arbitrary painting to a music box box for teaching materials.

As described above, according to the present invention, the work of connecting the lids becomes extremely easy, and it is possible to provide a music box box suitable for use as a teaching material or a souvenir of a graduation work.
