DETAILED DESCRIPTION OF THE INVENTION

[0032] Hereinafter, one embodiment of a toy according to the technology of the present disclosure will be described with reference to the drawings. Fig. 1 is a perspective view showing a toy 1 according to the technique of the present disclosure. Fig. 2 is a cross-sectional view of a portion taken along line AA in Fig. 1. Fig. 3 is an exploded perspective view of a containing member.

[0033] The toy 1 is a sound-making toy configured to generate sound using variations in air pressure in an internal space SP of an outer shell made of an elastic material. As shown in FIGS. 1 and 2, the toy 1 has an internal space SP sealed by a space-forming member 10 made up of a first sheet member 11 and a second sheet member 12 that form a predetermined space, and a housing member 15 that supports both sheet members 11 and 12. Pressure changes in the internal space SP are detected by elastic deformation of a portion of the second sheet member 12. An example of an operating unit that detects this pressure change is a detector 20 provided close to the first sheet member 11 inside the housing member 15.

[0034] As shown in the figure, the second sheet member 12 constituting the outer shell is made of an elastic material such as silicone rubber and has a rounded shape imitating a pufferfish-shaped character. The first sheet member 11 is provided in a flat circular shape at the upper end of the containing member 15 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 also configured to have a thinner thickness (t1) than the second sheet member 12. This makes the first sheet member 11 more susceptible to deformation than the second sheet member 12. Therefore, the first sheet member 11 has a larger amount of elastic deformation in response to pressure changes in a predetermined space than the second sheet member 12.

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

[0036] 2 and 3, the detection unit 20 that detects pressure changes in the internal space SP includes a displacement unit 23, a pressure sensor 25, and a biasing member 28 that are provided on the outer side (lower side in the drawings) of the first sheet member 11. The displacement unit 23 includes a circular upper flat surface portion 23a that is constantly in contact with the first sheet member 11, and a central cylindrical portion 23b that extends downward from the center of the upper flat surface portion 23a. The displacement unit 23 is held so that it can move up and down, with the central cylindrical portion 23b passing through a through-hole 15h (see FIG. 3) in the upper wall 15u of the housing member 15.

[0037] Furthermore, the coil spring biasing member 28 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. This biasing member 28 causes the upper flat portion 23a to contact the first sheet member 11 and separates the lower end surface 23d of the central cylindrical portion 23b from the pressure sensor 25. Furthermore, the displacement portion 23 moves in conjunction with the up and down movement of the first sheet member 11. Thus, the pressure sensor 25 can accurately detect the amount of change in the displacement of the displacement portion 23 in response to the displacement of the displacement portion 23.

[0038] 3, the displacement portion 23 is provided with, for example, a pair of restricting guide pieces 23e that protrude downward from the outer periphery of the upper flat portion 23a in parallel with the central cylindrical portion 23b. These restricting guide pieces 23e are used by a biasing member 28 to restrict the displacement portion 23 from moving too far upward. For example, the restricting guide pieces 23e are provided with hooking claws 23f (see FIG. 6) at their tips and are arranged to pass through the hook holes 15e in the upper wall 15u. When the displacement portion 23 is in the initial position (see FIG. 7), the hooking claws 23f engage with the upper wall 15u, restricting the upward movement of the displacement portion 23.

[0039] As shown in FIG. 3, the first sheet member 11 is circular and has multiple mounting holes 11h on its outer periphery. The housing member 15 is composed of a cylindrical outer wall surface 15a, a flange member 15b, and a bottom 15d. The bottom 15d is fitted 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 center and a thick fixing ring portion 15m surrounding the opening. The fixing ring portion 15m is provided with multiple screw mounting portions 15g, to which fastening screws 51 are attached. By fastening the fastening screws 51 with the first sheet member 11 sandwiched between the fixing ring portion 15m and the upper end surface 15j of the cylindrical outer wall surface 15a, the first sheet member 11 is tightly clamped and hermetically attached between the fixing ring portion 15m and the upper end surface 15j of the cylindrical outer wall surface 15a.

[0040] In this way, the first sheet member 11 can be attached mechanically without using adhesive, so that the adhesive does not drip, the assembly work is easy, and the configuration is also useful in terms of cost.

[0041] 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 the pressure P in the predetermined space increases. This operation, the details of which will be described later, causes the displacement portion 23 to come into contact with the pressure sensor 25 and output 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 portion 23 is separated 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.

[0042] 2, the storage member 15 is configured to have a size that can hold almost the entire lower portion of the second sheet member 12. As a result, when the second sheet member 12 is pressed in as shown in the figure, the storage member 15, which is made of a hard material, is firmly supported by the placement surface 60, allowing for a stable pressing operation.

[0043] FIG. 4 is an exploded perspective view showing an example of how to assemble the accommodating member 15, and FIG. 5 is an exploded perspective view showing an example of how to attach the holding member 30. As shown in FIG. The toy 1 is assembled, for example, as shown in FIGS. 4 and 5. First, as shown in FIG. 4, the housing member 15, into which the control unit 33 and the electrical system have been previously assembled, is inserted through the circular opening 12h on the lower side of the second sheet member 12 with the flange member 15b on the upper end side facing inward (the state shown in FIG. 4). During this insertion, the first seal portion 12a constituting the circular opening 12h is inserted while being widened. As a result, the first seal portion 12a is positioned so as to contact the cylindrical outer wall surface 15a of the housing member 15, and the flange member 15b is positioned so that the annular flange portion 15f on its outer periphery contacts the second seal portion 12b, and the flange member 15b is positioned so that the annular flange portion 15f contacts the second seal portion 12b.

[0044] Thereafter, the bottom 15c of the housing member 15 incorporating the control unit 33 and the electrical system is attached from below using the bottom screws 52. However, when attaching the bottom 15c, the bottom screws 52 are not fully tightened.

[0045] Thereafter, as shown in FIG. 5, the retaining member 30 is attached. For example, the retaining member 30, which is divided into a front half 31 and a rear half 32, is attached from the outside of the first seal portion 12a so that the screw bosses 31b, 32b fit together. In this fitted state, the bottom screw 52 is tightened. At this time, the lower end flange 15g formed on the outer peripheral edge of the lower end of the bottom portion 15c presses against the lower end of the retaining member 30. As a result, the first pressing portion 30a at the upper end of the retaining member 30 presses the second seal portion 12b from below with a strong force (arrow F1 in FIG. 6), sandwiching the second seal portion 12b between the first pressing portion 30a and the flange member 15b, thereby enhancing the airtightness.

[0046] FIG. 6 is an enlarged cross-sectional view illustrating the fastening structure of the second seal member 12. As shown in FIG. After the bottom screws 52 have been tightened, the fastening members 50 are tightened to fix the holding member 30. As shown in Fig. 6, the holding member 30 is provided on its inner side with a first pressing portion 30a at the top in the height direction, a second pressing portion 30b at the middle, and a third pressing portion 30c at the bottom, which form an annular tightening abutment portion.

[0047] The first, second, and third pressing portions 30a, 30b, and 30c are configured to press the first seal portion 12a in three stages, with their tips 30e toward the cylindrical outer wall surface 15a in the width direction of the first seal portion 12a (the direction away from the flange member 15b), as shown in the figure. That is, the tips 30e of the pressing portions 30a, 30b, and 30c press against the first seal portion 12a with a strong force (F2) so as to bite into the first seal portion 12a. Furthermore, the 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 held down by the tightening force (F1) applied by the bottom screw 52. That is, because forces are applied in different directions on either side of the boundary portion 12c, the boundary portion 12c is firmly pressed down, enhancing the sealing performance.

[0048] Fig. 7 is an enlarged schematic view showing the initial state of displacement portion 23 in the structure for detecting pressure changes, and Fig. 8 is an enlarged schematic view showing the operating state of displacement portion 23 in the structure for detecting pressure changes.

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

[0050] Furthermore, the area (A) of the first sheet member 11 that moves in response to a pressure change corresponds to the opening of the flange member 15b. The contact area (B) between the first sheet member 11 and the displacement portion 23 is smaller than this area (A). Furthermore, the pressing area (D) where the tip pressing portion 24 presses the pressure sensor 25 is smaller than this contact area (B). Furthermore, the area (C) of the pressure sensor 25 is configured to be slightly larger than the pressing area (D). By making the area (C) of the pressure sensor 25 larger than the pressing area (D), reliable sensing is possible without the tip pressing portion 24 protruding from the sensor surface. The area (C) of the pressure sensor 25 is smaller than the contact area (B). In this way, the area that moves in response to a pressure change is configured to become smaller as it approaches the pressure sensor 25, thereby amplifying the movement of the hand 70 during operation. The greater the number of stages in the area size relationship, the easier it is to increase the amplification range. For example, even the slightest movement of the hand 70 can be reliably detected. In particular, in a configuration that expresses a musical scale, a musical piece can be produced by subtle hand movements.

[0051] Furthermore, the first sheet member 11 is configured to be large so that it can receive pressure changes over a wide area. Meanwhile, in order to convert 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. The first sheet member 11 and the displacement portion 23 are not bonded with 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 deforms as shown in FIG. 8, the portion in contact with the restricting guide piece 23e undergoes very little elastic deformation (almost no deformation). Therefore, 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 portion 23 are bonded together with an adhesive or the like, the adhesive may peel off over time, which is undesirable because it changes the amount of displacement due to pressing. Furthermore, as the adhesive changes over time, it can even tear in severe cases. However, by not using an adhesive, as in this configuration, the long-term stability of the pressing state can be improved. Furthermore, the elimination of the bonding process improves workability and reduces manufacturing costs.

[0053] FIG. 9 is a cross-sectional view showing an example of a modified form of the second seal member 12. As shown in FIG. When the toy 1 is pressed with the hand 70, the mouth interior 12m changes to bulge outward as the first region 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 the initial state in which no pressure change is detected, the mouth interior 12m is configured to be recessed inward, and furthermore, its thickness (t3) is configured to be smaller than the thickness (t2) of the surrounding area. This makes the mouth interior 12m easily deformable, and elastic deformation occurs with each pressing operation, and the magnitude of the deformation changes depending on the pressing strength.

[0054] The inner mouth portion 12m is concave and curved toward the inside of the main body, while the lip portion 12n in the second region adjacent to the inner mouth portion 12m bulges outward in the opposite direction (outward) from the inner mouth portion 12m. The thickness of the lip portion 12n is greater than that of the inner mouth portion 12m. Furthermore, the lip portion 12n bulges differently from the inner mouth portion 12m. That is, the inner mouth portion 12m is gently curved, while the lip portion 12n is curved with a large curvature. This configuration suppresses deformation of the lip portion 12n by a pressing operation, making the deformation of the inner mouth portion 12m more noticeable. It is desirable that the thickness (t4) of the second seal member 12 around the lip portion 12n be greater than the thickness (t3) of the inner mouth 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 interior 12m and the lip portion 12n and deformation of the mouth interior 12m.

[0055] FIG. 10 is an enlarged cross-sectional view of the regulating valve 40 of the toy 1. As shown in FIG. 10, an adjustment valve 40 that adjusts the pressure inside the internal space SP is provided inside the housing member 15. This adjustment valve 40 includes a valve portion 41 that opens and closes an air hole 46 that communicates with the internal space SP, a force point portion 42 that presses the valve portion 41 against the air hole 46 and then releases the pressing and is separated from the valve portion 41, and a fulcrum portion 43 that is positioned on the opposite side of the valve portion 41 from and engages with the force point portion 42.

[0056] The valve portion 41 can be opened and closed by adjusting the force application member 45, which is composed of the engagement of the fulcrum portion 43 and a screw member provided on the force application member 42. For example, when the force application member 45 is turned in the loosening direction, the force application member 45 of the adjusting valve 40 opens the force application member 42 downward in the figure due to the biasing force of the pressure spring 48, loosening the pressure contact of the O-ring 49 by the valve portion 41 and allowing communication between the internal space SP and the outside air via the air hole 46. As a result, the second sheet member 12 is maintained in a bulged shape that maintains the internal air pressure of the specified space at approximately atmospheric pressure, and can be returned to an elastically deformable shape by pressing from the outside.

[0057] On the other hand, when closing the regulating valve 40, the force application member 45 is tightened, and the regulating valve 40 is rotated with the fulcrum part 43 engaged with the hook part 15g. As a result, using the principle of leverage, the valve part 41 presses the O-ring 49 with a very strong force, ensuring reliable closure. The adjusting valve 40 is covered by the outer lid 15d of the housing member 15. Therefore, the adjusting valve 40 cannot be seen from the outside, but an opening 15h for screwing is provided in the outer lid 15d. Therefore, the adjusting valve 40 is accessible from the outside only through the force application member 45 via the opening 15h.

[0058] As described above, in the toy 1 of this embodiment, the space-forming member 10 can deform and change the pressure in the internal space SP, and the toy 1 is equipped with a detection unit 20 that is located outside the specified space and is capable of detecting pressure changes in response to the deformation of the space-forming member 10.Therefore, in the toy 1 that operates using pressure changes based on the detection of the detection unit 20, it is easy to detect pressure changes in response to the deformation of the space-forming member 10 even if the toy 1 does not have high airtightness at the pressure P within the specified space, making it possible to provide a toy 1 with stable performance.

[0059] In the toy 1 of this embodiment, the detection unit 20 is provided with the displacement unit 23 that changes its position in response to a change in pressure, so that the pressure sensor 25 can easily convert this positional displacement into an electric signal.

[0060] Furthermore, since the displacement portion 23 is constantly biased in a direction 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 binary-coded.

[0061] In the toy 1 of this embodiment, the space forming member 10 includes the first sheet member 11 and the second sheet member 12, which have different amounts of elastic deformation, so that the amount of elastic deformation of one of the members, for example, the smaller amount of elastic deformation, can be amplified by the larger amount of elastic deformation. This makes it possible to reliably pick up small movements as large movements.

[0062] In particular, by configuring the outer shell of the toy 1 with 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, it is possible to accurately detect slight changes in the outer shell of the toy 1. As a result, it becomes easy to divide the strength of the pressing operation into multiple stages, and it is possible to provide a toy 1 that produces a wide range of musical notes.

[0063] Furthermore, in the toy 1 of this embodiment, the pressure sensor 25 is housed and held in the housing member 15 that does not elastically deform, so that the detection function of the detection unit 20 can be performed accurately.

[0064] In the toy 1 of this embodiment, 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 deformation amounts can be formed using the same material.

[0065] In the toy 1 of this embodiment, the second sheet member 12 has a multi-layer structure in which multiple sealing portions that tightly tighten and attach the holding member 30 to the storage member 15 are arranged in an overlapping manner, thereby ensuring reliable sealing.

[0066] 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 when the character is viewed from the front, the structure of the attachment part is not visible, maintaining good design.

[0067] In the toy 1 of this embodiment, the bottom side of the toy 1 is made of a hard storage member 15, and the size of the storage member 15 is configured to be 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, when pressing the second sheet member 12, the entire bottom side is made of a hard material, so that the force of the pressing operation can be stably received, improving operability.

[0068] According to the toy of this embodiment, by providing an adjustment valve 40 that adjusts the pressure of 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 pressure as atmospheric pressure, thereby simplifying the configuration without requiring any special pressurizing means.

[0069] Furthermore, adjusting valve 40 uses force application member 45, which has force point portion 42 and fulcrum portion 43 sandwiching valve portion 41, as a structure for operating valve portion 41 that opens and closes air hole 46, which increases the reliability of the closed state of valve portion 41 and at the same time makes it possible to move and accurately adjust the open state. Furthermore, valve portion 41 is configured so that only force point portion 42 is accessible from outer lid 15d, which ensures ease of adjustment and protects adjusting valve 40.

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

[0071] Furthermore, in the above-mentioned embodiment, the pressure fluctuations in the internal space SP are converted into sound, but this is not limited to this, and the configuration may also be such that light emission effects that change the intensity of light, or even color emission effects that change the color, are possible.

[0072] In the configuration of the above embodiment, the pressure medium in the internal space SP is air, but it is not limited to air and may be a liquid such as water. [Explanation of symbols]
