Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a pushbutton switch for toys, and particularly to a pushbutton switch that can operate reliably even under extreme handling.

[Prior Art] In recent years, with the development of electronic circuits, toys intended for use by children of elementary school age and younger are also incorporating small electrical devices, which can perform various operations in conjunction with the user's switch operations. It has been increasing.

However, it is inevitable that young children will use the switch more violently than the manufacturer imagined, and it is essential to develop a switch that guarantees reliable operation even under rough usage.

In response to such a demand, it has conventionally been common practice to provide a stopper on the push button of a switch, and to absorb the impact with the stopper, thereby preventing excessive pressure on the switch contacts.

[Problems to be solved by the invention] However, in the method of absorbing shock with a stopper,
Subtle adjustment of the pressing stroke is essential, which makes assembly troublesome, and there are many other problems, such as the adjustment becoming erroneous due to long-term heavy use, and the durability of the stopper itself being poor.

The present invention was made in view of the above problem, and is a delicate one! It has a simple configuration that does not require gI adjustment, and is durable.
I! is a push button switch for toys with excellent impact resistance and reliability. The purpose is to

c. Means for Solving Problems] FIG. 1 shows a schematic configuration of a pushbutton switch 21 according to the present invention, and shows a pressing section 50 that is actually operated by a child, and a pressing section 50 that is actually operated by a child. It is composed of a receiving part 49 that receives an impact applied to the part 50, an operating rod 51 that moves integrally with the pressing part 50, and a switch contact 52 that is turned on and off by pressing the operating rod 51.

Both the above-mentioned pressing part 50 and receiving part 49 can be sufficiently prevented from deformation even under excessive impact by increasing the thickness of the material or by appropriately reinforcing them with ribs, stays, etc. The receiving portion 49 is fixed to the main body case or the like, and the pressing portion 50 is pivoted at one end so that it can approach and move away from the receiving portion 49.

Contrary to the above, the operating rod 51 is made of a thin plate, etc.
The switch contact 52 is formed so that it can be operated but is deformed when a further force is applied, and its base end is fixed to the pressing part 50, and its tip is extended perpendicularly to the direction of movement of the pressing part 50. Furthermore, a switch contact 52 is arranged in the transition path at the tip.

[Function] In the above configuration, when a pressing force is applied to the pressing part 50 as shown in FIG. 1(a), the pressing part 50 moves toward the receiving part 49, and the pressing part 50 moves toward the receiving part 49 as shown in FIG. 1(b). While the operating rod 51 extending from the switch 50 relieves the impact force, the tip of the operating rod 51 pushes the switch contact 52 and closes the contact 52.

If the pressing force is further applied, the flexible operating rod 51 bends as shown in FIG. 1(c) to completely absorb the pressing force and prevent excessive pressing of the switch contact 52. At the same time, the impact applied to the pressing portion 50 is absorbed by the hard receiving portion 49, and reliable switch operation is performed regardless of the magnitude of the pressing force.

[Example] Figures 2 to 4 show a small-sized timer device that emits a predetermined sound at a set time in a stuffed toy doll.

1 shows an example in which the present invention is implemented, but the present invention is not limited to this, and it goes without saying that the present invention can be implemented in substantially the same way as push button switches for various toys such as ride-on toys.

Stuffed toy doll 1] is a flexible sheet member,
A bag 15 having a predetermined character shape having a head 13 and a body 14 is formed, and the interior is filled with a soft material such as cotton fiber or sponge, except for a storage chamber 16 in which the small device 12 is stored. The bag body 15 tightly filled with the bag body 17 has a protrusion 18 formed by slightly protruding the position corresponding to the "navel" part on the front side, and a small a-type device 12 can pass through the bottom surface 19 side. An opening 20 of a large size is formed to communicate with the storage chamber 16, and the small device 12 inserted into the storage chamber 16 inside the bag 15 through the opening 20 is inserted so that the tip 22 of the operation switch 21 is connected to the storage chamber 16. The operation switch 2 is inserted into the protrusion 18 and is inserted from the front side of the doll 11.
1, and the lower peripheral edge of the main body case 23 is fixed to the opening 20 of the bag body 15 as described later,
The main body case 23 is positioned within the bag body 15.

The small A-type device 12 has an upper case 24 and a lower case 25 joined together to form a flat hollow cylindrical body case 23. Inside the body case 23, an operation switch 21, a speaker 26, and a circuit are installed. An electric circuit including the board 27 is arranged! The battery compartment 2 is located on the lower surface 28 side of the lower case 25.
9 and a timer setting section 30 are recessed, and a small machine is installed inside the doll 11. 512, it is possible to replace the battery or operate the setting switch 31 from the outside.

The battery storage section 29 has a size that can accommodate, for example, four AA size dry batteries in parallel, and the opening 32 therebetween is large enough to accommodate four AA batteries in parallel.
It is covered with a lid that can be opened and closed freely. The battery cover 33 has a rectangular thin plate shape that substantially coincides with the opening 32 of the battery storage section 29, and has a rotating shaft 34 protruding from the base end side surface toward both sides.
Slide grooves 35 are formed on both sides of the timer setting section 30 adjacent to the battery storage section 29, and the rotation shaft 3 is formed in the slide grooves 35.
4 is slidably and rotatably supported. Further, on the tip edge of the battery cover 33, there are finger hook protrusions 3 on both sides with the locking claw 36 in the center.
On the other hand, at the corresponding position on the lower case 25 side when the battery '1i33 is closed, there is a substantially hemispherical finger hook groove 38 whose half is covered by the finger hook protrusion 37, and a locking claw 36 that engages and disengages. A locking groove 39 into which it can be freely fitted is formed.

The timer setting section 30 forms a groove 40 adjacent to the battery storage section 29, and includes a battery M33 in the groove 40.
Four through-holes 41 are formed perpendicularly to the sliding direction of the bushing switch 4 , and a bushing switch 4 is formed at an opposing position on the circuit board 27 .
2 is fixed, and a switch button 43 is attached between the switch 42 and the through hole 41. The switch button 43 is
The cap-shaped base end 44 is fitted into the pressing part 45 of the switch 42, the thin shaft-shaped tip 46 is made to protrude from the through hole 41, and the tip of the leaf spring 47 extending laterally from the center is fixed near the through hole 41. By doing so, four sets of setting switches 31 are configured. Note that the leaf spring 47 of the switch button 43 relieves the pressing force by itself to prevent excessive pressing of the switch 42, and the tip of the leaf spring 47 is previously connected so that it can be separated by a joining technique 48. This allows the relatively small switch button 43 to be handled in one go, making it easy to assemble the switch button 43.

The operation switch 21 includes a thick plate-shaped receiving part 49 fixed to the main body case 23, a pressing part 50 arranged so as to be able to move toward and away from the receiving part 49, and a thin plate-shaped part extending from the pressing part 50. an operating rod 51, and a switch contact 52 fixed on the circuit board 27 and turned on and off at the tip of the operating rod 51.
The present invention is characterized by the configuration of such an operation switch.

The receiving portion 49 has a receiving surface 5 sufficient for the pressing portion 50 to come into contact with it.
3 is provided on the front side, while the back side is supported by the stay 54, so that the impact force received by the pressing part 50 can be received and absorbed without deformation.

The pressing part 50 has a rectangular cylindrical shape at the base end and a cylindrical shape at the distal end to provide sufficient strength against deformation similarly to the receiving part 49, and the distal end surface 22 is formed with irregularities such as concentric grooves. The bag body 15 is formed into a hemispherical shape with 55 when pressed.
The proximal end surface 56 is made flat, and the impact applied to the distal end surface 22 is dispersed and uniformly applied to the receiving part 49, while preventing the switch from slipping off and making the switch operation reliable and easy. In other words, the pressing part 50 has its rectangular tube part inserted into the guide groove 57 of the main body case 23 to regulate the transition path, and the proximal end surface 56
A round bar-shaped pivot portion 58 is provided parallel to the short side of the hook-shaped receiving portion 5 and the pivot portion 58 is provided at the base end of the receiving portion 49.
9, the entire pressing section 50 can be freely rotated around the pivot portion 58, while a spring body 60 disposed between the center of the base end surface 56 of the pressing section 50 and the receiving surface 53 allows the pressing section 50 to be rotated. The tip surface 2 of the pressing part 50 is biased outward.
Regardless of the magnitude and direction of the force applied to 2, the pivot portion 58 and the guide groove 57 correct the direction of movement of the pressing portion 45, so that the entire proximal end surface 56 can be reliably received by the receiving portion 49. .

The operating rod 51 provided on the pressing section 50 is a narrow thin plate that extends linearly from the short side opposite to the pivot portion 58 on the same plane as the base end surface 56 of the pressing section 50. A pressing shaft 61 is provided protruding from the tip toward the transition direction, and a switch contact 52 is arranged on the circuit board 27 close to a position facing the pressing shaft 61. Due to the bending configuration, when a force is applied to the pressing part 50, that force is also applied to the pressing shaft 61 via the operating rod 51, but the magnitude of the bending force is inversely proportional to the distance from the pivot part 58, Therefore, in this embodiment, the force applied to the pressing shaft 61 is divided into about half, and the operating rod 51 is curved to absorb the impact, thereby preventing excessive impact from being applied and suppressed to the switch contact 52. When the switch contact 52 is operated reliably and the pressing part 50 is further pushed forward, the receiving part 49 prevents the pressing part 50 from moving.

The main body case 23 that houses each of the above-mentioned parts has an uneven portion 62 formed on its outer peripheral surface.In this embodiment, a plurality of small holes 64 are provided on the upper surface of the upper case 24, Number of sounds output 6 of internal speaker 26
3, and a plurality of thin shaft-shaped convex portions 62a are formed on the emission surface 63, while a groove-shaped concave portion 6 is formed on the circumferential side.
2b is formed. The uneven portion 62 prevents the filling 17 from biting into the filling 17 when placed in the filling 17 in the second doll 11 and causing the filling 17 to partially move and become unbalanced when external pressure such as a twisting force is applied. At the same time, the number of sounds is 6
The convex portion 62a provided around the ring 3 forcibly forms a gap 65 with the filler 17, and also prevents the small hole 64 of the sound output surface 63 from being completely obstructed. Note that a part or all of the uneven portion 62 is used as a screw receiving portion 66 when screwing the main body case 23 from the inside or outside.

The small a device 12 incorporated into the doll 11 as described above
The main body case 23 is inserted into the opening 2o provided on the bottom surface 19 of the bag body.
The body case 23, whose lower surface side is fixed, has a narrow flange 67 projecting outward from the lower surface to support the opening rim 68 of the bag body 15 from the outside, and to support the opening rim 68 of the bag body 15 from the outside. A ring-shaped locking part 7o having a gripping surface 69 of a size corresponding to the flange part 67 is provided inside the bag body 15 so as to be inserted through the main body case 23. Furthermore, a plurality of bell-shaped small protrusions 71 that can penetrate the bag body 15 are protruded from the flange part 67 at approximately equal intervals, while the small protrusions 71 at the locking part 7°
A small hole-shaped recess 72 into which the protrusion 71 fits is formed at the abutting position of the protrusion 71, and when the flange 67 and the locking part 70 are tightly engaged with the four wood screws 73, the protrusion 71 is inserted into the bag. It bites into the opening periphery 68 of the body 15 to firmly fix the main body case 23 to the bag body 15. Note that the locking portion 7o is attached to the clamping surface 6
A cylindrical support surface 74 extends from the outer periphery of the flange 9 to cover the outer periphery of the flange 67, and when the main body case 23 is fixed to the bag body 15, the lower end 75 of the support surface 74 touches the lower surface 28 of the main body case 23. By setting the length so as to reach a little lower, the bag body 15 acts as a cushion when the doll is placed with the lower surface 28 of the main body case 23 facing down.

[Effects of the Invention] As described above, the present invention includes a pressing section 50 to which a human applies force,
The part that actually turns on and off the switch contact 52 is separated, and both are connected via the operating rod 51.
The pressing part 50 and the receiving part 49 are formed to be sufficiently strong so that they can withstand large impacts, while the operating rod 51 is deformable so as to transmit only the force necessary and sufficient to operate the switch. This has the advantage that it has a simple configuration and can perform stable and reliable switch operations even in extreme operations.
