[Modes for carrying out the invention]

[0032] Hereinafter, an embodiment of a toy relating to the technology of this disclosure will be described with reference to the figures. Figure 1 is a perspective view showing toy 1 according to the technology of this disclosure. Figure 2 is a cross-sectional view of the portion along line AA in Figure 1. Figure 3 is an exploded perspective view of the housing member.

[0033] Toy 1 is a sound-generating toy configured to produce sound using fluctuations in the air pressure of the internal space SP within an outer shell made of an elastic material. As shown in Figures 1 and 2, Toy 1 has an internal space SP sealed by a space-forming member 10 consisting of a first sheet member 11, a second sheet member 12 that form a predetermined space, and a housing member 15 that supports both sheet members 11 and 12. The pressure change in the internal space SP is detected when a part of the second sheet member 12 elastically deforms. As an operating unit for detecting this pressure change, for example, a detection unit 20 is provided close to the first sheet member 11 inside the housing member 15.

[0034] The second sheet member 12, which constitutes the outer shell, is made of an elastic material such as silicone rubber, which is modeled after a pufferfish character, as shown in the figure, and is made in a rounded shape. The first sheet member 11 is provided in a circular, flat shape at the upper end of the housing member 15, which is located below the second sheet member 12. The first sheet member 11 is also made of the same silicone rubber as the second sheet member 12. Furthermore, the thickness (t1) of the first sheet member 11 is thinner 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 amount of elastic deformation of the first sheet member 11 in response to pressure changes in a predetermined space is greater than that of the second sheet member 12.

[0035] Furthermore, the control unit 33, which detects pressure changes and converts them into electrical signals, is equipped with a power supply 36, a control board 37, a speaker 38, etc., and converts pressure changes into sound. The sounds produced by the toy 1 can represent musical scales. For example, it can represent musical scales of two treble or more. For this musical scale representation, for example, when a force change in the internal space SP is detected, the signal corresponding to the strength of that pressure change can be expressed as a musical scale.

[0036] The detection unit 20 for detecting changes in the internal space SP pressure includes a displacement unit 23, a pressure sensor 25, and a biasing member 28, as shown in Figures 2 and 3, which are located on the outside (lower side in the figures) of the first sheet member 11. The displacement unit 23 includes a circular upper flat portion 23a that is in constant contact with the first sheet member 11, and a central cylindrical portion 23b that extends downward from the center of the upper flat portion 23a. The displacement unit 23 is held so as to be able to move up and down by having the central cylindrical portion 23b pass through a through hole 15h (see Figure 3) in the upper wall 15u of the housing member 15.

[0037] Furthermore, the biasing member 28 of the coil spring is positioned to surround the outside of the central cylindrical portion 23b and is provided between the upper flat portion 23a and the upper wall 15u. This biasing member 28 brings the upper flat portion 23a into contact with the first sheet member 11, while the lower end surface 23d of the central cylindrical portion 23b is spaced apart from the pressure sensor 25. The displacement portion 23 is also linked to the vertical movement of the first sheet member 11. The pressure sensor 25 can accurately detect the amount of change in the displacement portion 23 in accordance with the displacement of the displacement portion 23.

[0038] Furthermore, as shown in Figure 3, the displacement section 23 is provided with, for example, a pair of restrictive guide pieces 23e that protrude downward from the outer circumference of the upper flat section 23a parallel to the central cylindrical section 23b. These restrictive guide pieces 23e are used by the biasing member 28 to prevent the displacement section 23 from moving too far upward. For example, the restrictive guide piece 23e is provided with a hooking claw 23f (see Figure 6) at its tip and is positioned to penetrate the claw hole 15e of the upper wall 15u. When the displacement section 23 is in its initial position (see Figure 7), this hooking claw 23f engages with the upper wall 15u, thereby restricting the upward movement of the displacement section 23.

[0039] As shown in Figure 3, the first sheet member 11 is circular in shape, and multiple mounting holes 11h are provided on its outer edge. The housing member 15 is composed of a combination of a cylindrical outer wall surface 15a, a flange member 15b, and a bottom portion 15d. The bottom portion 15d is incorporated inside the cylindrical outer wall surface 15a, and the flange member 15b is attached to the upper side of the cylindrical outer wall surface 15a so as to sandwich the first sheet member 11. The flange member 15b has an opening in its central part, and a thick fixing ring portion 15m surrounds this opening. Multiple screw mounting portions 15g are provided on this fixing ring portion 15m, and are configured to accommodate tightening screws 51. Then, by tightening the tightening screws 51 with the first sheet member 11 sandwiched between them, the first sheet member 11 is tightly fastened and sealed between the fixing ring portion 15m and the upper end surface 15j of the cylindrical outer wall surface 15a.

[0040] Thus, since the first sheet member 11 is attached mechanically without using adhesive, there is no dripping of adhesive, assembly work is easy, and it is a cost-effective configuration.

[0041] In the assembled toy 1, when the upper part of the second sheet member 12 is pressed, for example, by a hand 70 (see Figure 2), the second sheet member 12 deforms and the pressure P in the predetermined space increases. As a result of this operation, although the details will be described later, the displacement unit 23 contacts the pressure sensor 25 and emits a signal corresponding to the pressure change caused by the pressing force. On the other hand, when the second sheet member 12 is not deformed, the displacement unit 23 is separated from the pressure sensor 25, and no signal is emitted from the pressure sensor 25. By sensing in this way, the on / off state of the signal can be clearly separated.

[0042] Furthermore, as is clear from Figure 2, the receiving member 15 is configured to hold almost the entire lower portion of the second sheet member 12. As a result, when an operation such as pressing the second sheet member 12 is performed as shown in the figure, the receiving member 15, which is made of a rigid material, is firmly supported on the mounting surface 60, enabling a stable pressing operation.

[0043] Figure 4 is an exploded perspective view showing an example of how the housing member 15 is assembled, and Figure 5 is an exploded perspective view showing an example of how the retaining member 30 is attached. When assembling toy 1, for example, it is assembled as shown in Figures 4 and 5. First, as shown in Figure 4, the housing member 15, which has the control unit 33 and electrical system already assembled, is inserted through the lower circular opening 12h of the second sheet member 12 with the upper flange member 15b facing inward (state as in Figure 4). When inserting it, the first sealing portion 12a that constitutes the circular opening 12h is widened. As a result, the first sealing portion 12a is positioned to be in contact with the cylindrical outer wall surface 15a of the housing member 15, and the flange member 15b is positioned so that its outer annular flange portion 15f is in contact with the second sealing portion 12b.

[0044] Subsequently, the bottom 15c of the housing member 15, which incorporates the control unit 33 and electrical system, is attached from below using bottom screws 52. However, the bottom 15c is left in a state where the bottom screws 52 are not fully tightened.

[0045] Subsequently, as shown in Figure 5, the retaining member 30 is attached. To attach the retaining member 30, for example, the retaining member 30, which is divided into a front half 31 and a rear half 32, is fitted together from the outside of the first seal portion 12a by fitting the respective screw bosses 31b and 32b. With the retaining member 30 fitted together, the aforementioned bottom screw 52 is tightened. At this time, the lower end flange portion 15g formed on the lower outer peripheral edge of the bottom portion 15c presses against the lower end of the retaining member 30. As a result, the retaining member 30's upper end first pressing portion 30a presses against the second seal portion 12b from below with strong force (arrow F1 in Figure 6), sandwiching the second seal portion 12b between the first pressing portion 30a and the flange member 15b, thereby improving the airtightness.

[0046] Figure 6 is an enlarged cross-sectional view illustrating the tightening structure of the second sealing member 12. After the bottom screws 52 have been tightened, the fastening member 50 is tightened to fix the retaining member 30. As shown in Figure 6, the retaining member 30 has an annular tightening contact portion on its inside, consisting of a first pressing portion 30a at the top, a second pressing portion 30b in the middle, and a third pressing portion 30c at the bottom, in the height direction.

[0047] 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 sealing portion 12a in three stages in the width direction of the first sealing portion 12a (away from the flange member 15b) toward the cylindrical outer wall surface 15a, as shown in the figure. That is, the tips 30e of each pressing portion 30a, 30b, and 30c press against the first sealing portion 12a with a strong force (F2) by biting into it. Furthermore, the boundary portion 12c between the first sealing portion 12a and the second sealing portion 12b is pressed by the tip 30e of the first pressing portion 30a, and is also firmly held in place by the tightening force (F1) applied by the bottom screw 52. In other words, because forces in different directions are applied across the boundary portion 12c, it is firmly held in place and the airtightness is enhanced.

[0048] Figure 7 is an enlarged schematic diagram showing the initial state of the displacement unit 23 in the structure for detecting pressure changes. Figure 8 is an enlarged schematic diagram showing the operating state of the displacement unit 23 in the structure for detecting pressure changes.

[0049] In toy 1, when no operation is being performed that causes a pressure change, as shown in Figure 7, the displacement part 23 is pressed upward by the biasing member 28, and its upper end portion is in contact with the first sheet member 11. At this time, the tip pressing part 24 provided on the lower side of the lower end surface 23d of the displacement part 23 is separated from the pressure sensor 25. Also in this state, the restricting guide piece 23e of the displacement part 23 is designed to catch on the upper wall 15u, thereby restricting the upward movement of the displacement part 23. The tip pressing part 24 is made of a relatively flexible material such as urethane.

[0050] Furthermore, the area (A) of the first sheet member 11 that moves due to pressure changes corresponds to the opening portion of the flange member 15b. The contact area (B) between the first sheet member 11 and the displacement part 23 is smaller than this area (A). Also, the pressing area (D) where the tip pressing part 24 presses against the pressure sensor 25 is smaller than this contact area (B). Moreover, 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 part 24 does not extend beyond the sensor surface, enabling reliable sensing. Note that 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, which allows for amplification of the movement caused by the operation of the hand 70. The more steps there are in this relationship between the size of the areas, the easier it becomes to increase the amplification width. For example, even the slightest movement of the hand can be reliably detected. In particular, in compositions that express musical scales, subtle hand movements can produce sound.

[0051] Furthermore, the first sheet member 11 is made large so that it can receive pressure changes over a wide area. On the other hand, in order to convert the pressure changes received over a large area into large movements, the tip pressing portion 24 is small compared to the area over which the first sheet member 11 can move. Note that the first sheet member 11 and the displacement portion 23 are not bonded together with adhesive or anything like that. However, since the first sheet member 11 is made of silicone or the like, its surface is sticky, and when the first sheet member 11 deforms as shown in Figure 8, the part that is in contact with the regulating guide piece 23e undergoes extremely small elastic deformation (almost no deformation). As a result, the elastic deformation of the first sheet member 11 forms an annular region (E), which allows for large movements relative to its size.

[0052] Furthermore, if the first sheet member 11 and the displacement part 23 are bonded together with an adhesive, the adhesive may peel off due to long-term use. This is undesirable because it changes the amount of displacement due to pressure. In addition, deterioration of the bonded part over time can cause tearing in severe cases, but by not using an adhesive, as in this configuration, the long-term stability of the compressed state can be improved. Moreover, the absence of an adhesive process improves workability and reduces manufacturing costs.

[0053] Figure 9 is a cross-sectional view showing an example of a deformed form of the second sealing member 12. When toy 1 is pressed with hand 70, the mouth interior 12m of the pufferfish character changes to bulge outwards. This is caused by the configuration in which the thickness of the second sheet member 12 is changed. For example, in the initial state when no pressure change is detected, the mouth interior 12m is configured to be recessed inward, and its thickness (t3) is smaller than the thickness (t2) of the surrounding part. As a result, the mouth interior 12m is easily deformed, elastic deformation occurs with each pressing operation, and the magnitude of the deformation changes depending on the force of the press.

[0054] The interior of the opening 12m is concave and curves inward toward the inside of the main body, while the lip portion 12n in the second area adjacent to the interior of the opening 12m bulges outward in the opposite direction (outward). Furthermore, the lip portion 12n is thicker than that of the interior of the opening 12m. Moreover, the way the lip portion 12n bulges is different from that of the interior of the opening 12m. That is, while the curvature of the interior of the opening 12m is gentle, the curvature of the lip portion 12n is configured to be more curvature. Due to this configuration, when the deformation of the lip portion 12n is suppressed by the pressing operation, the deformation of the interior of the opening 12m becomes more prominent. It is desirable that the thickness (t4) of the second sealing member 12 around the lip portion 12n is greater than the thickness (t3) of the interior of the opening 12m and less than the thickness (t2) of the lip portion 12n. This configuration makes it easy to achieve both deformation of the first sheet member 11 due to deformation of the second sealing member 12 other than the mouth interior 12m and lip portion 12n, and deformation of the mouth interior 12m.

[0055] Figure 10 is an enlarged cross-sectional view of the adjustment valve 40 of toy 1. As shown in Figure 10, a regulating valve 40 is provided inside the housing member 15 to adjust the pressure inside the internal space SP. This regulating valve 40 comprises a valve portion 41 that opens and closes an air hole 46 communicating with the internal space SP, a force point portion 42 that presses the valve portion 41 against the air hole 46 and releases the pressure, and a pivot portion 43 that is positioned on the opposite side of the force point portion 42 across the valve portion 41 and engages with it.

[0056] The valve portion 41 can be opened and closed by the engagement of the pivot portion 43 and the adjustment of the force application member 45, which is composed of a screw member provided on the force application portion 42. For example, when the force application member 45 is turned in the loosening direction, the adjustment valve 40 opens downwards in the figure due to the biasing force of the compression spring 48, the pressure contact of the O-ring 49 by the valve portion 41 is loosened, and the internal space SP and the outside air are connected through the air hole 46. As a result, the second seat member 12 is maintained in a bulging shape that maintains the internal air pressure of the predetermined space at approximately atmospheric pressure, and can be returned to a shape that can be elastically deformed by external pressure.

[0057] On the other hand, when closing the adjustment valve 40, tightening the force point member 45 causes the adjustment valve 40 to rotate with the fulcrum 43 engaged with the hook 15g. As a result, the valve portion 41 presses the O-ring 49 with a very strong force using the lever principle, ensuring complete closure. The adjustment valve 40 is covered by the outer cover 15d of the housing member 15. Therefore, the adjustment valve 40 cannot be seen from the outside, but the outer cover 15d is provided with an opening 15h for screwing. Thus, the adjustment valve 40 is accessible from the outside only through the opening 15h to the force point member 45.

[0058] As described above, in the toy 1 of this embodiment, the space-forming member 10, which can deform to change the pressure in the internal space SP, is equipped with a detection unit 20 located outside the predetermined space that can detect the pressure change corresponding to the deformation. Therefore, in the toy 1, which operates using the pressure change detected by the detection unit 20, it becomes easy to detect the pressure change corresponding to the deformation of the space-forming member 10 even without high airtightness at the pressure P in the predetermined space, making it possible to provide a toy 1 with stable performance.

[0059] In this embodiment of toy 1, the detection unit 20 is equipped with a displacement unit 23 that changes position in response to pressure changes, making it easy to convert this positional displacement into an electrical signal using the pressure sensor 25.

[0060] Furthermore, since the displacement unit 23 is constantly biased away from the pressure sensor 25, the on / off operation of the pressure sensor 25, which is linked to the deformation of the space forming member 10, can be accurately and reliably binarized.

[0061] In the toy 1 of this embodiment, the space-forming member 10 comprises a first sheet member 11 and a second sheet member 12 with different amounts of elastic deformation, making it possible to amplify the amount of elastic deformation of one of them, for example, the one with the smaller amount of elastic deformation, with the one with the larger amount of elastic deformation. This makes it possible to reliably pick up small movements as large movements.

[0062] In particular, by constructing the outer shell of the toy 1 with a second sheet member 12 that has a small amount of elastic deformation, and placing the first sheet member 11, which has a large amount of elastic deformation, on the side that presses the pressure sensor 25, even 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 a toy 1 that can produce a wide range of musical notes can be provided.

[0063] Furthermore, in the toy 1 of this embodiment, the pressure sensor 25 is housed and held within the housing member 15 which does not elastically deform, thereby enabling the detection function of the detection unit 20 to be accurate.

[0064] In this embodiment of toy 1, the thickness of the first sheet member 11 is made thinner than the thickness of the second sheet member 12, thereby making it possible to form members that change the amount of deformation using the same material.

[0065] In this embodiment of toy 1, the second sheet member 12 is arranged in a multi-layered structure in which multiple sealing portions are stacked on top of each other and attached to the storage member 15 by the holding member 30 being tightly fastened, thereby ensuring a secure seal.

[0066] Furthermore, since the fastening member 50 that tightens and secures the second sheet member 12 is attached from the rear side of the character of the toy 1, the structure of the attachment part is not visible when the character is viewed from the front, thus maintaining a good aesthetic appearance.

[0067] In this embodiment of toy 1, the bottom side of toy 1 is made of a rigid storage member 15, and its size is made to be approximately the same as the size of the bottom surface of the pressable second sheet member 12, so that it can be placed stably on the mounting surface 60. Furthermore, when pressing the second sheet member 12, the entire bottom side is made of a rigid material, so that the force of the pressing operation can be stably received, improving operability.

[0068] According to this embodiment of the toy, by providing an adjustment valve 40 for adjusting the pressure in the internal space SP, it is possible to respond to changes in atmospheric pressure, and for example, the inflated state of the second sheet member 12 can be maintained at approximately the same level as atmospheric pressure, thus simplifying the structure without requiring special pressurizing means.

[0069] Furthermore, the adjustment valve 40 uses a force point member 45 that has a force point portion 42 and a pivot point portion 43 on either side of the valve portion 41 as a structure for operating the valve portion 41 that opens and closes the air hole 46. This increases the reliability of the closed state of the valve portion 41 and allows for precise movement and adjustment of the open state. Moreover, the valve portion 41 is configured so that only its force point portion 42 is accessible from the outer cover 15d, ensuring ease of adjustment and protecting the adjustment valve 40.

[0070] Although one aspect of the technology of this disclosure has been described above, the technology of this disclosure can be modified as appropriate within the scope of its technical concept. For example, in the above embodiment, the operating unit is configured to change its position linearly based on the pressure change detected by the detection unit 20, but the configuration of this operating unit is not limited to this, and for example, it may be configured to rotate, or even to perform electronic fluctuations.

[0071] Furthermore, the above embodiment is not limited to a configuration in which pressure fluctuations in the internal space SP are converted into sound, but may also be configured to allow for light emission effects that change the intensity of light, and even color emission effects that change the color.

[0072] Furthermore, in the configuration described above, the pressure medium in the internal space SP is air, but it is not limited to air; it may also be a liquid such as water. [Explanation of Symbols]
