Abstract

PROBLEM TO BE SOLVED: To enable a child to show interest in the changes that a mask offers and to use this mask without boring for a long time by arranging a sensor operated by an air pressure on the inner side of the mouth portion of a mask body and allowing LEDs to emit light by the operation of the sensor. SOLUTION: An electric circuit 5 is arranged on the inner side of the forehead 4 and two through-holes 6, 6 are penetrated and formed on the surface in the central part of the forehead 4 apart a suitable spacing above and below. The LEDs 7, 7 which emit light are respectively arranged on the inner side of these through-holes 6, 6. Further, the sensor 8 is arranged on the inner side of the mouth 2 portion. When the air is blown into a cylindrical body 9 from its rear part, an operating plate 10 moves forward by overcoming the spring force of a leaf spring and comes into contact with a contact plate 12, causing the current by a power source to flow. When the sensor 8 is operated by the air pressure, i.e., when the operating plate 10 comes into contact with the contact plate 12, the current by the power source flows in the electric circuit 5 which causes the LEDs 7 to emit light. The current is shut off and the light emission of the LEDs 7 is stopped when the operating plate 10 parts from the contact plate 12.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface mainly used for play of children and the like.

[0002]

2. Description of the Related Art Conventionally, various surfaces made of plastic, paper, and the like are known.

[0003]

However, the conventional aspects are as follows.
Although all have features in shape and structure, children are tired of short-term because of constant expression and little change.

[0004] The present invention has been made in view of the above-mentioned problems of the conventional surface, and is configured such that when the surface is covered, the LED emits light by blowing air with a mouth. It is an object of the present invention to provide a surface in which a child has a change, is interested, and can use it for a long time without getting tired.

[0005]

In order to achieve the above object, the surface of the present invention comprises a pneumatically-operated sensor disposed inside a mouth portion of a surface body and electrically connected to the sensor. And a power supply and the like, and a circuit is configured such that the LED emits light by operating a sensor, and the LED is arranged at a forehead of the surface main body and other desired positions.

[0006]

When the face is put on the face and air is blown from the mouth to the sensor, the sensor works by the air pressure, a current flows, and the LED in the circuit emits light. The light emission time of the LED is determined according to the time at which air is blown against the sensor. Therefore, when air is blown for a long time, the LED continues to emit light only during that time. For example, when air is blown intermittently to the sensor, the LED blinks.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1 shows a front view of the entire surface, FIG. 2 shows an electric circuit, and FIG. 3 shows an exploded perspective view of the sensor. As shown in FIG. 1, the surface main body 1 is formed, for example, of metal, wood, plastic, cardboard or the like into a desired outer shape, and is formed by opening the mouths 2, eyes 3, 3 at predetermined positions. I have.

An electric circuit 5 shown in FIG. 2 is arranged inside the forehead 4 of the surface main body 1, and on the surface of the central part of the forehead 4, two Through holes 6, 6
Are formed to penetrate, and LEDs 7, 7 for emitting light are arranged inside the through holes 6, 6, respectively. In addition, mouth 2
The sensor 8 is arranged inside the portion.

The sensor 8 is configured as follows. As shown in FIGS. 2 and 3, an operation plate 10 made of a good conductor is inserted into a tubular body 9 made of an insulator in a front-rear direction (left and right directions in FIG. 2) via a weak spring 11 made of a good conductor. A contact plate 12 made of a good conductor is fixed to the inside of the front end of the cylindrical body 9 so as to come into contact with the operating plate 10 when the operating plate 10 is moved forward. , 14 are connected to each other, and air is blown from the inside of the surface main body 1, that is, into the cylindrical body 9 in FIG.
0 moves forward against the spring force of the leaf spring 11, comes into contact with the contact plate 12, and the current flows from the power supply 15 shown in FIG.
When the blowing of air into the cylindrical plate 9 is stopped, the operation plate 10 is moved by the spring force of the plate spring 11 as shown in FIG.
As shown in (1), it is configured to retreat and be separated from the contact plate 12 to be cut off.

[0010] As shown in FIG.
Two short slits 9a and 9b are opened at the front end of the cylindrical body 9 and are provided side by side in the longitudinal direction.
The fixed and terminal piece 1 is inserted from the front end opening and protrudes from the base end of the leaf spring 11 in a direction perpendicular to the longitudinal direction of the leaf spring.
The leaf spring 1a is fixed to the surface of the cylindrical body 9 with screws or the like.
1 may be arranged in the cylinder 9.

The operating plate 10 and the leaf spring 11 can be integrally formed by pressing a metal plate having a good conductor spring property. The operating plate 10 may be formed so as to be in surface contact with the contact plate 12, but as shown in FIG. 3, a tongue-shaped contact piece 10a is cut over the operating plate 10 and Can be formed so as to contact with.

A terminal strip 12 is provided on a part of the periphery of the contact plate 12.
a, which is inserted into the slit 9b of the cylindrical body 9 and fixed to the surface of the cylindrical body 9 with a screw or the like to fix the contact plate 12
May be fixed in the cylindrical body 9.

The leaf spring 11 has a fixed and terminal piece 11.
The contact plate 12 has the terminal pieces 12a to which the above-mentioned wirings 13 and 14 are connected.

The electric circuit 5 shown in FIG. 2 operates when the sensor 8 is operated by air pressure as described above, that is, when the operating plate 1 is operated.
When 0 is in contact with the contact plate 12, a current flows from the power supply 15 and the LED 7 emits light.
The circuit is configured so that when the LED 7 is separated from the power source 2, the light is cut off and the light emission of the LED 7 is stopped.

As shown in FIG. 1, when the wirings 13 and 14 are arranged side by side at regular intervals vertically from the sensor 8 at the mouth 2 of the surface main body 1 to the electric circuit 5 at the upper forehead 4 as shown in FIG. The wires 13 and 14 are expressed like a nose, and the expression of the surface becomes rich.

As the power supply 15, a small battery of, for example, 3 to 6 V is used. The positions of the LEDs 7 other than the positions shown, for example, above the eyes 3 and 3 and other positions are arbitrary.

Further, according to the present invention, by incorporating a generator 16 such as a buzzer into the electric circuit 5, sound can be emitted as required instead of light emission, or both light emission and sound emission can be emitted. it can. This generator 16 may be provided at any position on the surface main body 1 as long as it does not interfere with the mounting.

[0018]

Since the present invention is configured as described above, it emits light when it is put on the face and blows air to the sensor with the mouth, and this light emission mode also makes the air blowing longer or shorter. , And intermittently, since it is changed variously by various other changes, the expression of the surface body and the synergistic effect of various light emission modes are rich in changes,
The expression becomes richer, and the child is particularly interested and can be used for a long time without getting tired.
