CROSS-REFERENCE TO RELATED APPLICATION

This application is based upon and claims the benefit of priority from Japanese Patent Application No. 2024-022458, filed on Feb. 16, 2024, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to a toy.

BACKGROUND ART

In the related art, there have been provided sound-producing toys. For example, JP7286203B discloses a toy including a housing unit and an audio module unit, where the housing unit includes a hollow housing main body having flexibility and shape-restoring properties, and an accommodation portion accommodating the audio module unit therein. The audio module unit includes an air pressure sensor that detects changes in internal pressure in the housing main body due to deformation of the housing main body, a processing means that converts a detection value of the air pressure sensor into audio information, and an output unit that outputs the audio information.

In JP7286203B, the audio module unit is built in the airtight housing main body having flexibility and shape-restoring properties. This requires high sealing performance of the housing main body.

An object of the present disclosure is to provide a toy that has stable performance without requiring high airtightness.

DESCRIPTION OF EMBODIMENTS

Hereinafter, an aspect of a toy according to the present disclosure will be described with reference to the drawings.

FIG. 1 is a perspective view illustrating a toy 1 according to the present disclosure. FIG. 2 is a cross-sectional view of a portion taken along the line A-A in FIG. 1. FIG. 3 is an exploded perspective view of an accommodating member.

The toy 1 is a sound-making toy configured to generate sound by using variations in air pressure in an internal space SP of an outer shell portion made of an elastic material. As illustrated in FIGS. 1 and 2, in this toy 1, the internal space SP is formed that is sealed by a space defining member 10 consisting of a first sheet member 11, a second sheet member 12 that form a specified space, and a accommodating member 15 that supports both sheet members 11 and 12. A part of the second sheet member 12 elastically deforms and a pressure change in the internal space SP is detected. As an operating unit for detecting this pressure change, for example, a detector 20 is provided in a vicinity of the first sheet member 11 inside the accommodating member 15.

The second sheet member 12 forming an outer shell is, as illustrated in the figure, made of an elastic material such as silicone rubber in a rounded shape, for example, in the shape of a pufferfish character. The first sheet member 11 is provided in a circular, flat shape on an upper end of the accommodating member 15 that is disposed below the second sheet member 12. The first sheet member 11 is made of the same silicone rubber as the second sheet member 12. The first sheet member 11 is configured to have a thickness (t1) smaller than that of the second sheet member 12. As a result, the first sheet member 11 is more easily deformed than the second sheet member 12. Therefore, the first sheet member 11 has a larger amount of elastic deformation in response to a pressure change in a specified space than the second sheet member 12.

A control unit 33, which detects pressure changes and converts them into electrical signals, is provided with a power source 36, a control board 37, a speaker 38, and the like, and converts the pressure changes into sound. The sounds produced by the toy 1 are capable of expressing a musical scale. For example, it is possible to express a musical scale of two or more octaves. As for this musical scale expression, for example, when a pressure change in the internal space SP is detected, a signal corresponding to strength of the pressure change can be expressed as a musical scale.

The detector 20 for detecting pressure changes in the internal space SP includes a displacement member 23, a pressure sensor 25, and a biasing member 28 provided on an outer side (a lower side in the figure) of the first sheet member 11, as illustrated in FIGS. 2 and 3. The displacement member 23 includes an upper flat portion 23a having a circular shape that is constantly in contact with the first sheet member 11, and a central cylindrical portion 23b that extends downward from a center of the upper flat portion 23a. The displacement member 23 is supported so that the central cylindrical portion 23b is vertically movable with passing through a through hole 15h (see FIG. 3) in an upper wall 15u of the accommodating member 15.

The biasing member 28 made of a coil spring is positioned so as to surround the outside of the central cylindrical portion 23b, and is provided between the upper flat portion 23a and the upper wall 15u. The biasing member 28 causes the upper flat portion 23a to be in contact with the first sheet member 11 and causes a lower end surface 23d of the central cylindrical portion 23b to be spaced away from the pressure sensor 25. In addition, the displacement member 23 moves in conjunction with vertical movement of the first sheet member 11. The pressure sensor 25 can accurately detect an amount of change in the displacement member 23 in response to the displacement of the displacement member 23.

As illustrated in FIG. 3, the displacement member 23 is provided with, for example, a pair of restricting guide pieces 23e which protrude downward from an outer periphery of the upper flat portion 23a in parallel with the central cylindrical portion 23b. The restricting guide piece 23e restricts the displacement member 23 from moving too far upward by the biasing member 28. For example, the restricting guide piece 23e has a hooking claw 23f (see FIG. 6) at its tip and is provided so as to pass through a hook hole 15e of the upper wall 15u. When the displacement member 23 is in an initial position (see FIG. 7), the hooking claw 23f engages with the upper wall 15u, thereby restricting the displacement member 23 from moving upward.

As illustrated in FIG. 3, the first sheet member 11 is formed in a circular shape, and has a plurality of mounting holes 11h formed on its outer periphery. The accommodating member 15 is constructed by combining a cylindrical outer wall surface 15a, a flange member 15b, and a bottom portion 15d. The bottom portion 15d is fitted inside the cylindrical outer wall surface 15a, and the flange member 15b is attached to an upper side of the cylindrical outer wall surface 15a so as to pinch the first sheet member 11 therebetween. The flange member 15b has an opening at its center and is provided with a fixed ring portion 15m with a high thickness and surrounding the opening. The fixed ring portion 15m is provided with a plurality of screw attachment portions 15g, and is configured to receive tightening screws 51. Then, by pinching the first sheet member 11 and tightening the first sheet member with the tightening screws 51, the first sheet member 11 is tightly clamped between the fixed ring portion 15m and an upper end surface 15j of the cylindrical outer wall surface 15a and attached in a sealed state.

In this way, the first sheet member 11 can be attached mechanically without using adhesive, so that no adhesive drips, the assembly work is easy, and the configuration is also useful in terms of cost.

In the assembled toy 1, when the upper part of the second sheet member 12 is pressed by, for example, a hand 70 (see FIG. 2), the second sheet member 12 deforms and a pressure P in the specified space increases. Through this operation, the displacement member 23 comes into contact with the pressure sensor 25 and outputs a signal in accordance with a pressure change caused by the pressing force, the details of which will be described below. On the other hand, when the second sheet member 12 is not deformed, the displacement member 23 is apart from the pressure sensor 25, and no signal is output from the pressure sensor 25. By sensing in this way, it is possible to clearly distinguish between on and off signals.

As is apparent from FIG. 2, the accommodating member 15 is configured to have a size sufficient to hold almost the entirety of a lower part of the second sheet member 12. As a result, when the second sheet member 12 is pressed in as illustrated in the figure, the accommodating member 15 made of a hard material is firmly supported by a placement surface 60, allowing for a stable pressing operation.

FIG. 4 is an exploded perspective view illustrating an example of how to assemble the accommodating member 15, and FIG. 5 is an exploded perspective view illustrating an example of how to attach the holding member 30.

The toy 1 is assembled, for example, as illustrated in FIGS. 4 and 5. First, as illustrated in FIG. 4, the accommodating member 15, into which a control unit 33 and an electrical system are assembled in advance, is inserted through a circular opening portion 12h on the lower side of the second sheet member 12 with the flange member 15b on an upper end side facing inward (a state illustrated in FIG. 4). During this insertion, the insertion is performed while widening a first seal portion 12a forming the circular opening portion 12h. As a result, the first seal portion 12a is positioned so as to be in contact with the cylindrical outer wall surface 15a of the accommodating member 15, and the flange member 15b is positioned so that its outer circumferential annular flange portion 15f is in contact with the second seal portion 12b, and the flange member 15b is positioned so that the annular flange portion 15f is in contact with the second seal portion 12b.

Thereafter, the bottom portion 15c of the accommodating member 15, in which the control unit 33 and the electrical system are assembled, is attached from below using bottom screws 52. However, the bottom portion 15c is attached in a state in which the bottom screw 52 is not completely tightened.

Thereafter, as illustrated in FIG. 5, a holding member 30 is attached. The holding member 30 is attached, for example, by fitting the holding member 30, which is divided into a front half 31 and a rear half 32, from the outside of the first seal portion 12a so that screw bosses 31b and 32b fit together. In this fitted state, the bottom screws 52 described above are tightened. In this case, a lower end flange 15g formed on an outer periphery of a lower end of the bottom portion 15c presses a lower end of the holding member 30. As a result, a first pressing portion 30a at the upper end of the holding member 30 presses the second seal portion 12b from below with a strong force (arrow F1 in FIG. 6), pinching the second seal portion 12b between the first pressing portion 30a and the flange member 15b, thereby improving the airtightness.

FIG. 6 is an enlarged cross-sectional view for illustrating a fastening structure of a second seal member 12. After the bottom screw 52 is tightened, a fastening member 50 is tightened to fix the holding member 30 in place. As illustrated in FIG. 6, on the inside of the holding member 30, the first pressing portion 30a at the top, a second pressing portion 30b at the middle, and a third pressing portion 30c at the bottom are provided in a height direction, which form annular constricting abutment portions.

The first pressing portion 30a, the second pressing portion 30b, and the third pressing portion 30c are structured so that their tips 30e press against the first seal portion 12a in three stages in a width direction (a direction away from the flange member 15b) of the first seal portion 12a toward the cylindrical outer wall surface 15a as illustrated in the figure. That is, the tip 30e of each of the pressing portions 30a, 30b, and 30c presses against the first seal portion 12a with a strong force (F2) so as to bite into the first seal portion 12a. Furthermore, a boundary portion 12c between the first seal portion 12a and the second seal portion 12b is pressed by the tip 30e of the first pressing portion 30a, and is firmly pressed by a tightening force (F1) applied by the bottom screw 52. That is, since forces are applied in different directions on either side of the boundary portion 12c, the boundary portion 12c is firmly pressed down and the airtightness is improved.

FIG. 7 is an enlarged schematic view illustrating an initial state of the displacement member 23 in a structure for detecting a pressure change. FIG. 8 is an enlarged schematic view illustrating an operating state of the displacement member 23 in the structure for detecting the pressure change.

In the toy 1, when no operation that would cause a pressure change is performed, as illustrated in FIG. 7, the displacement member 23 is pressed upward by the biasing member 28, and its upper end portion is in contact with the first sheet member 11. In this case, a tip pressing portion 24 provided on a lower surface side of the lower end surface 23d of the displacement member 23 is apart from the pressure sensor 25. In this state, the restricting guide piece 23e of the displacement member 23 is hooked on the upper wall 15u, restricting the upward movement of the displacement member 23. The tip pressing portion 24 is made of a relatively flexible material such as urethane.

Further, an area (A) of the first sheet member 11 that moves due to a pressure change is a region that corresponds to the opening of the flange member 15b. A contact area (B) between the first sheet member 11 and the displacement member 23 is smaller than this area (A). Furthermore, a pressing area (D) where the tip pressing portion 24 presses against the pressure sensor 25 is smaller than the contact area (B). Furthermore, the area (C) of the pressure sensor 25 is configured to be slightly larger than the pressing area (D). This is because by making the area (C) of the pressure sensor 25 larger than the pressing area (D), the tip pressing portion 24 does not protrude from a sensor surface, allowing reliable sensing. The area (C) of the pressure sensor 25 is smaller than the contact area (B). In this way, the area that moves due to pressure changes is configured to become smaller as it approaches the pressure sensor 25, so that the pressure caused by the operation of the hand 70 can be amplified. The greater the number of steps in the area size relationship, the easier it is to increase the amplification. For example, even a slight movement of the hand 70 can be detected reliably. In particular, in a configuration that expresses a musical scale, a piece of music can be produced by subtle movements of the hand.

Moreover, the first sheet member 11 is configured to be large so as to be able to widely receive pressure changes. On the other hand, in order to convert the pressure change received over a large area into a large pressure, the tip pressing portion 24 is made smaller than the area over which the first sheet member 11 can move. The first sheet member 11 and the displacement member 23 are not bonded together with an adhesive or the like. However, since the first sheet member 11 is made of silicon or the like, its surface is sticky, and when the first sheet member 11 is deformed as illustrated in FIG. 8, the portion in contact with the restricting guide piece 23e undergoes extremely small elastic deformation (almost no deformation). Therefore, the elastic deformation of the first sheet member 11 forms an annular region (E), and is capable of large movement in proportion to its size.

Furthermore, when the first sheet member 11 and the displacement member 23 are bonded together with an adhesive or the like, the adhesive may peel off due to long-term use or the like. This undesirably changes an amount of fluctuation caused by the pressure. Furthermore, as an adhesive portion changes over time, in severe cases it may even tear. However, by not using an adhesive as in this configuration, it is possible to improve the long-term stability of the pressing state. Furthermore, since there is no adhesive step, workability is improved and manufacturing costs can be reduced.

FIG. 9 is a cross-sectional view illustrating an example of a deformation form of the second seal member 12.

When the toy 1 is pressed by the hand 70, a mouth inner portion 12m changes to bulge outward as a first area of the pufferfish character. This is caused by the configuration in which the thickness of the second sheet member 12 is changed. For example, in an initial state in which no pressure change is detected, the mouth inner portion 12m is configured to be recessed toward the inside of the main body, and furthermore, its thickness (t3) is configured to be smaller than the thickness (t2) of its surrounding parts. This makes the mouth inner portion 12m easily deformable, and elastic deformation occurs with each pressing operation, and the magnitude of deformation changes depending on the strength of pressing.

The mouth inner portion 12m is recessed so as to curve toward the inside of the main body, but a lip portion 12n of a second area adjacent to the mouth inner portion 12m bulges in an opposite direction (outward) from the mouth inner portion 12m. The lip portion 12n is configured to be thicker than the mouth inner portion 12m. Furthermore, the lip portion 12n bulges differently from the mouth inner portion 12m. That is, the mouth inner portion 12m is gently curved, whereas the lip portions 12n are curved with a large curvature. With this configuration, the lip portion 12n is placed in a state in which deformation is suppressed by a pressing operation, so that the deformation of the mouth inner portion 12m appears more prominent. It is preferable that the thickness (t4) of the second seal member 12 around the lip portion 12n is greater than the thickness (t3) of the mouth inner portion 12m and smaller than the thickness (t2) of the lip portion 12n. With this configuration, it is possible to easily achieve both deformation of the first sheet member 11 due to deformation of the second seal member 12 other than the mouth inner portion 12m and the lip portion 12n and deformation of the mouth inner portion 12m.

FIG. 10 is an enlarged cross-sectional view of a regulating valve 40 of the toy 1. As illustrated in FIG. 10, the regulating valve 40 for regulating the pressure inside the internal space SP is provided inside the accommodating member 15. This regulating valve 40 includes a valve portion 41 which opens and closes an air hole 46 which communicates with the internal space SP, a force point portion 42 which presses the valve portion 41 against the air hole 46 and then releases this pressing and is away from the valve portion 41, and a fulcrum portion 43 which is positioned on an opposite side of the valve portion 41 to the force point portion 42 and is engaged with the force point portion.

The valve portion 41 can be opened and closed by adjusting a force point member 45 which is constituted by engagement of the fulcrum portion 43 and a screw member provided on the force point portion 42. For example, when the force point member 45 is turned in a loosening direction, in the regulating valve 40, the force point portion 42 opens downward in the figure due to the biasing force of a pressure spring 48, pressure-contact of an O-ring 49 by the valve portion 41 loosens, and the internal space SP is connected to the outside air via the air hole 46. As a result, the second sheet member 12 is maintained in a bulged shape in which the internal air pressure of the specified space is at substantially atmospheric pressure, and can be returned to an elastically deformable shape by pressure from the outside.

On the other hand, when closing the regulating valve 40, the force point member 45 is tightened, whereby the regulating valve 40 is rotated with the fulcrum portion 43 engaged with a hook portion 15g. As a result, the valve portion 41 can press the O-ring 49 with a very strong force using the principle of leverage, ensuring reliable closure.

The regulating valve 40 is covered with an outer lid 15d of the accommodating member 15. For this reason, the regulating valve 40 cannot be seen from the outside, but an opening 15h for screwing is provided in the outer lid 15d. Therefore, the regulating valve 40 is accessible only to the force point member 45 via the opening 15h from the outside.

As described above, in the toy 1 of this aspect, the space forming member 10 can change the pressure in the internal space SP by deformation, and the detector 20 can detect the pressure change corresponding to the deformation and is provided outside the specified space. Therefore, in the toy 1 that operates using pressure changes based on the detection of the detector 20, it is easy to detect pressure changes corresponding to the deformation of the space defining member 10 even when the toy 1 does not have high airtightness at the pressure P in the specified space, making it possible to provide the toy 1 with stable performance.

In the toy 1 of this aspect, the detector 20 is provided with the displacement member 23 that changes its position in response to a pressure change, so that this positional displacement can be easily converted into an electrical signal by the pressure sensor 25.

In addition, since the displacement member 23 is constantly biased in a direction away from the pressure sensor 25, the on/off operation of the pressure sensor 25, which coordinates with the deformation operation of the space defining member 10, can be accurately and reliably binary-coded.

In the toy 1 of this aspect, the space defining member 10 is provided with the first sheet member 11 and the second sheet member 12 which have different amounts of elastic deformation, so that it is possible to amplify the amount of elastic deformation of one of the sheet members, for example the one with the smaller amount of elastic deformation, by the one with the larger amount of elastic deformation. This makes it possible to reliably pick up small movements as large movements.

In particular, by constructing the outer shell of the toy 1 from the second sheet member 12, which has a small amount of elastic deformation, and providing the first sheet member 11, which has a large amount of elastic deformation, on the side that presses the pressure sensor 25, slight changes in the outer shell of the toy 1 can be accurately detected. As a result, it becomes easy to divide the strength of the pressing operation into multiple stages, and it is possible to provide the toy 1 that produces a wide range of musical scale sounds.

Furthermore, in the toy 1 of this aspect, the pressure sensor 25 is accommodated and held within the accommodating member 15 which does not elastically deform, thereby enabling the detection function of the detector 20 to be accurate.

In the toy 1 of this aspect, the thickness of the first sheet member 11 is configured to be thinner than the thickness of the second sheet member 12, so that members with different amounts of deformation can be formed using the same material.

In the toy 1 of this aspect, the second sheet member 12 has a multiple structure in which a plurality of sealing portions are arranged in an overlapping manner to tightly tighten and attach the holding member 30 to the accommodating member 15, thereby ensuring reliable sealing.

Furthermore, the fastening member 50 that tightens and fixes the second sheet member 12 is structured to be attached from the rear side of the character of the toy 1, so that when the character is viewed from the front, the structure of the attachment portion is not visible, and good design can be maintained.

In the toy 1 of this aspect, the bottom side of the toy 1 is made up of the accommodating member 15 with hardness, the size of which is approximately the same as the bottom size of the second sheet member 12 that can be pressed, so that the toy 1 can be placed stably on the placement surface 60. Furthermore, since the entirety of the bottom side is made of a hard material when the second sheet member 12 is pressed, the force of the pressing operation can be stably received, improving operability.

With the toy of this aspect, by providing the regulating valve 40 that regulates the pressure in the internal space SP, it is possible to respond to changes in atmospheric pressure. For example, an inflated state of the second sheet member 12 can be maintained at approximately the same pressure as atmospheric pressure, so that no special pressurizing means is required and the configuration can be simplified.

Furthermore, the regulating valve 40 uses the force point member 45 having the force point portion 42 and the fulcrum portion 43 on either side of the valve portion 41 as a structure for operating the valve portion 41 which opens and closes the air hole 46, which increases the reliability of the closed state of the valve portion 41 and at the same time makes it possible to accurately adjust the open state. Furthermore, the valve portion 41 is configured so that only the force point portion 42 thereof can be accessed from the outer lid 15d, thereby ensuring ease of adjustment and protecting the regulating valve 40.

Although one aspect of the present disclosure is described above, the present disclosure can be modified as appropriate within the scope of its technical concept. For example, in the above aspect, the operating unit operates to change its position linearly based on the pressure change detected by the detector 20, but the configuration of this operating unit is not limited to this and may be, for example, a configuration that performs rotational movement or even an electronically varying movement.

In addition, in the above-described aspect, the pressure fluctuation in the internal space SP is converted into sound, but the aspect is not limited to this, and it is also possible to have a configuration that allows for light emission effects that change the intensity of light, and even color effects that change the color.

In the configuration of the above-described aspect, the pressure medium in the internal space SP is air, but the pressure medium is not limited to air and may be a liquid such as water.
