[0118] Hereinafter, one embodiment of a toy according to the technology disclosed herein will be described with reference to the drawings.

[0119] Figure 1It is a perspective view of a toy 1 showing the technology of the present disclosure. Figure 2 It is along Figure 1 A cross-sectional view of the portion along the AA line in FIG. Figure 3 It is an exploded perspective view of the storage component.

[0120] The toy 1 is a sound-generating toy that generates sound by utilizing the change in air pressure in the inner space SP of the outer shell portion formed of an elastic material. Figure 1 and Figure 2 As shown, the toy 1 is formed with an internal space SP sealed by a space forming member 10, and the space forming member 10 includes a first sheet member 11, a second sheet member 12 for forming a predetermined space, and a storage member 15 for supporting the two sheet members 11 and 12. And, the pressure change of the internal space SP is detected by the local elastic deformation of the second sheet member 12. As an action part for detecting the pressure change, for example, a detection part 20 is provided close to the first sheet member 11 in the storage member 15.

[0121] As shown in the figure, the second sheet member 12 constituting the outer shell is formed into a rounded shape by elastic members such as silicone rubber imitating a pufferfish-shaped character. In addition, the first sheet member 11 is set to a circular flat shape at the upper end of the storage member 15 disposed on the lower side of the second sheet member 12. In addition, the first sheet member 11 is made of the same silicone rubber as the second sheet member 12. In addition, the first sheet member 11 is configured so that its thickness (t1) is thinner than the second sheet member 12. As a result, compared with the deformation of the second sheet member 12, the first sheet member 11 is easy to deform. Therefore, the elastic deformation amount of the first sheet member 11 caused by the pressure change of the specified space is greater than that of the second sheet member 12.

[0122] In addition, the control unit 33 that detects the pressure change and converts it into an electrical signal is provided with a power supply 36, a control substrate 37, a speaker 38, etc., for converting the pressure change into sound. In addition, the sound emitted by the toy 1 can express a musical scale. For example, a musical scale of more than two octaves can be expressed. As the musical scale expression, for example, the following structure can be set: when the 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.

[0123] like Figure 2 and Figure 3As shown in FIG. 1 , the detection unit 20 for detecting the pressure change in the internal space SP includes a displacement unit 23 provided on the outer side (lower side in the figure) of the first sheet member 11, a pressure sensor 25, and a force applying member 28. The displacement unit 23 includes a circular upper plane portion 23a that is always in contact with the first sheet member 11 and a central cylindrical portion 23b that extends downward from the center of the upper plane portion 23a. The displacement unit 23 passes through the through hole 15h (see FIG. 15b ) of the upper wall 15u of the storage member 15 through the central cylindrical portion 23b. Figure 3 ) and is maintained to be able to move up and down.

[0124] In addition, the urging member 28 of the coil spring is located at a position surrounding the outer side of the central cylindrical portion 23b and is provided between the upper plane portion 23a and the upper wall 15u. The urging member 28 makes the upper plane portion 23a contact the first sheet member 11 and separates the lower end surface 23d of the central cylindrical portion 23b from the pressure sensor 25. In addition, the displacement portion 23 is linked to the up-and-down movement of the first sheet member 11. Moreover, the pressure sensor 25 can accurately detect the amount of change of the displacement portion 23 according to the displacement of the displacement portion 23.

[0125] In addition, if Figure 3 As shown, the displacement portion 23 is provided with a pair of limiting guide pieces 23e protruding from the outer circumference of the upper flat surface portion 23a and the central cylindrical portion 23b toward the lower side in parallel. The limiting guide pieces 23e are used to limit and prevent the displacement portion 23 from excessively moving upward due to the force applying member 28. For example, the limiting guide piece 23e is provided with a hook claw 23f at the front end (see Figure 6 ) and penetrates the claw hole 15e of the upper wall 15u. When the displacement portion 23 is in the initial position (refer to Figure 7 ), the hook claw 23f engages with the upper wall 15u, thereby limiting the upward movement of the displacement portion 23.

[0126] like Figure 3 As shown, the first sheet member 11 is circular, and a plurality of mounting holes 11h are provided on its outer periphery. In addition, the storage member 15 is composed of a combination of a cylindrical outer wall surface 15a, a flange member 15b and a bottom 15d. The bottom 15d is assembled on the inner side of the cylindrical outer wall surface 15a, and the flange member 15b is installed on the upper side of the cylindrical outer wall surface 15a in a manner of clamping the first sheet member 11. The central part of the flange member 15b is opened, and a thick-walled fixing ring portion 15m is provided in a manner of surrounding the opening. A plurality of screw member mounting portions 15g are provided on the fixing ring portion 15m, which is configured to install a fastening screw member 51. And, in a state of clamping the first sealing member 11, the fastening screw member 51 is used for fastening, so that the first sheet member 11 is strongly fastened between the fixing ring portion 15m and the upper end surface 15j of the cylindrical outer wall surface 15a, and is installed in a sealed state.

[0127] In this way, the first sheet member 11 is mechanically attached without using an adhesive, so that dripping of the adhesive does not occur, the assembly work is easy, and the structure is also effective in terms of cost.

[0128] In the assembled toy 1, for example, when the hand 70 presses the upper portion of the second sheet member 12 (see Figure 2 ), the second sheet member 12 is deformed, and the pressure P in the predetermined space increases. Through this operation, the displacement portion 23 contacts the pressure sensor 25, and outputs a signal corresponding to the pressure change caused by the pressing force, and the details thereof will be described later. On the other hand, the displacement portion 23 is separated from the pressure sensor 25 when the second sheet member 12 is not deformed, and no signal is output from the pressure sensor 25. By sensing in this way, it is possible to clearly distinguish between the on and off of the signal.

[0129] In addition, from Figure 2 It can be seen that the storage member 15 is configured to hold substantially the entire area of ​​the lower portion of the second sheet member 12. Thus, when the second sheet member 12 is pressed in as shown in the figure, the storage member 15 formed of a hard member is reliably supported on the mounting surface 60, thereby enabling a stable pressing operation.

[0130] Figure 4 1 is an exploded perspective view showing an example of an assembly method of the storage member 15. Figure 5 It is an exploded perspective view showing an example of a method of attaching the holding member 30 .

[0131] When assembling the toy 1, for example, Figure 4 and Figure 5 Assemble as shown. First, Figure 4 As shown, the storage member 15 in which the control unit 33 and the electrical system are assembled is inserted from the circular opening 12h on the lower side of the second sheet member 12 in advance with the flange member 15b on the upper end side arranged inside ( Figure 4 During the insertion, the first sealing portion 12a constituting the circular opening 12h is inserted in a manner of stretching out. As a result, the first sealing portion 12a is located at a position in contact with the cylindrical outer wall surface 15a of the storage member 15, and the flange member 15b is located at a position where the annular flange portion 15f of the outer periphery thereof contacts the second sealing portion 12b, and the flange member 15b is located at a position where the annular flange portion 15f contacts the second sealing portion 12b.

[0132] Then, the bottom 15c of the storage member 15 is mounted from below using the bottom screws 52, and the control unit 33 and the electrical system are assembled to the storage member 15. However, the bottom 15c is mounted in a state where the bottom screws 52 are not completely tightened.

[0133] Then, if Figure 5 As shown, the retaining member 30 is installed. For example, the retaining member 30 divided into the front half 31 and the rear half 32 is fitted from the outside of the first sealing portion 12a by fitting the threaded protrusions 31b and 32b. In this fitted state, the bottom screw 52 is tightened. At this time, the lower end flange portion 15g formed on the outer peripheral edge of the lower end of the bottom 15c presses 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 is pressed from below with a strong force ( Figure 6 The second sealing portion 12b is pressed as indicated by the arrow F1, and the second sealing portion 12b is sandwiched between the first pressing portion 30a and the flange member 15b to improve the sealing performance.

[0134] Figure 6 It is an enlarged cross-sectional view for explaining the fastening structure of the second sealing member 12 .

[0135] After the bottom screw 52 is tightened, the fastening member 50 is tightened to fix the holding member 30. Figure 6 As shown, the retaining member 30 is provided with the following structure, wherein on the inner side of the retaining member 30 in its height direction, the topmost 1st pressing portion 30a, the middle 2nd pressing portion 30b and the bottom 3rd pressing portion 30c constitute an annular fastening abutment portion.

[0136] As shown in the figure, the first pressing part 30a, the second pressing part 30b and the third pressing part 30c are structured such that the front end 30e is pressed in three sections relative to the first sealing part 12a toward the cylindrical outer wall surface 15a in the width direction of the first sealing part 12a (in the direction away from the flange member 15b). That is, the front end 30e of each pressing part 30a, 30b, 30c is pressed with a strong force (F2) in a way of biting into the first sealing part 12a. Moreover, the boundary part 12c between the first sealing part 12a and the second sealing part 12b is pressed by the front end 30e of the first pressing part 30a, and is reliably pressed by the tightening force (F1) based on the bottom screw 52. That is, the boundary part 12c is applied with forces in different clamping directions, so it is reliably pressed to improve the airtightness.

[0137] Figure 7 2 is an enlarged schematic diagram showing the initial state of the displacement portion 23 in the structure for detecting pressure changes. Figure 8 It is an enlarged schematic diagram showing the operating state of the displacement portion 23 in the structure for detecting pressure changes.

[0138] In the toy 1, when no operation to generate pressure change is performed, Figure 7As shown in FIG. 1 , the displacement portion 23 is pressed upward by the force applying member 28, and the upper end portion of the displacement portion 23 contacts the first sheet member 11. At this time, the front end 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. In addition, in this state, the limiting guide piece 23e of the displacement portion 23 is hooked on the upper wall 15u to limit the upward movement of the displacement portion 23. The front end pressing portion 24 is composed of a relatively soft member such as polyurethane.

[0139] In addition, the area (A) of the first sheet member 11 that moves due to pressure changes is the area corresponding to the opening portion of the flange member 15b. Relative to this area (A), the contact area (B) between the first sheet member 11 and the displacement portion 23 is small. In addition, relative to this contact area (B), the pressing area (D) of the front end pressing portion 24 pressing the pressure sensor 25 is small. And the area (C) of the pressure sensor 25 is configured to be slightly larger than the pressing area (D). In this regard, by making the area (C) of the pressure sensor 25 larger than the pressing area (D), the front end pressing portion 24 will not exceed the sensor surface, and reliable sensing can be performed. In addition, the area (C) of the pressure sensor 25 is smaller than the above-mentioned 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 movement caused by the operation of the hand 70 can be amplified. The more levels of the size relationship of the area, the easier it is to increase the amplification range. For example, even if the movement of the hand 70 is a small movement, the movement can be reliably detected. In particular, in the structure that expresses the scale, it is possible to play music through subtle hand movements.

[0140] In addition, the first sheet member 11 is formed to be relatively large so as to bear pressure changes over a wide range. On the other hand, in order to convert the pressure changes borne by a large area into a large movement, the front end pressing portion 24 is relatively small compared to the area where the first sheet member 11 can move. In addition, the first sheet member 11 and the displacement portion 23 are not bonded by adhesive or the like. However, since the first sheet member 11 is made of silicon or the like, its surface has adhesiveness. Figure 8 When deformed as shown, the elastic deformation of the portion in contact with the limiting guide piece 23e is extremely small (almost not deformed). Therefore, the elastic deformation of the first sheet member 11 is the annular region (E), and a large movement can be performed in proportion to the size.

[0141] In addition, if the first sheet member 11 and the displacement portion 23 are bonded by adhesive or the like, the adhesive may be peeled off due to long-term use. As a result, the amount of change caused by pressing may change, which is not desirable. In addition, due to the change of the bonding part over the years, damage may occur in severe cases, but by not using an adhesive as in this structure, the long-term stability of the pressing state can be improved. In addition, since there is no bonding process, the workability is good and the cost of manufacturing can be suppressed.

[0142] Fig. 9 It is a cross-sectional view showing an example of a deformation state of the second sealing member 12 .

[0143] When the toy 1 is pressed by hand 70, the first range of the pufferfish character, the inner part 12m of the mouth changes in a manner of bulging outward. This is caused by changing the structure of the thickness of the second sheet member 12. For example, the inner part 12m of the mouth is configured to be concave toward the inside of the main body in the initial state where no pressure change is detected, and is configured so that its thickness (t3) is smaller than the thickness (t2) of the surrounding part. As a result, the inner part 12m of the mouth is easily deformed, and elastic deformation is caused every time a pressing operation is performed. In addition, the size of the deformation changes according to the pressing strength.

[0144] The inner part 12m of the mouth is recessed in a manner that bends toward the inner side of the main body, but the lip 12n of the second range adjacent to the inner part 12m of the mouth bulges in the direction opposite to the inner part 12m of the mouth (outside). In addition, the lip 12n is configured so that its thickness is thicker than the thickness of the inner part 12m of the mouth. Moreover, the bulging manner of the lip 12n is different from that of the inner part 12m of the mouth. That is, the curvature of the inner part 12m of the mouth is a gentle curvature, while the curvature of the lip 12n is a structure with a large curvature. Due to such a structure, the deformation of the lip 12n caused by the pressing operation is suppressed, so that the deformation of the inner part 12m of the mouth appears more significant. In addition, the thickness (t4) of the portion of the second sealing member 12 located around the lip 12n is expected to be greater than the thickness (t3) of the inner part 12m of the mouth and less than the thickness (t2) of the lip 12n. With such a configuration, it is possible to easily balance deformation of the port inner portion 12 m and deformation of the first sheet member 11 caused by deformation of the portion of the second sealing member 12 other than the port inner portion 12 m and the lip portion 12 n.

[0145] Fig.10 It is an enlarged cross-sectional view of the regulating valve 40 of the toy 1 .

[0146] like Fig.10As shown, a regulating valve 40 for regulating the pressure inside the internal space SP is provided in the storage member 15. The regulating valve 40 includes: a valve portion 41 that opens and closes an air hole 46 connected to the internal space SP; a force point portion 42 separated from the valve portion 41, which presses the valve portion 41 relative to the air hole 46 and releases the pressing; and a fulcrum portion 43, which is arranged and engaged with the force point portion 42 on the opposite side of the valve portion 41.

[0147] Furthermore, the opening and closing of the valve portion 41 can be performed by the engagement of the fulcrum portion 43 and the adjustment of the force point member 45 composed of a screw member provided on the force point portion 42. For example, when the force point member 45 is rotated in the loosening direction, the regulating valve 40 opens the force point portion 42 to the lower side in the figure by the force of the pressing spring 48, the pressure contact of the valve portion 41 to the O-ring 49 is loosened, and the internal space SP is connected to the external atmosphere through the air hole 46. Thus, the second sheet member 12 can be maintained in a bulging shape that maintains the internal air pressure of the predetermined space at substantially the atmospheric pressure, and can be restored to a shape that can be elastically deformed by external pressure.

[0148] On the other hand, when closing the regulating valve 40, the regulating valve 40 rotates with the fulcrum 43 engaged with the hook 15g by tightening the force point member 45. Thus, the valve portion 41 can reliably close by pressing the O-ring 49 with a very strong force by the lever principle.

[0149] The regulating valve 40 is covered by the outer cover 15d of the housing member 15. Therefore, the regulating valve 40 cannot be seen from the outside, but the outer cover 15d is provided with an opening 15h for a screwdriver. Therefore, for the regulating valve 40, only the power point member 45 can be inserted from the outside through the opening 15h.

[0150] As described above, in the toy 1 of this form, the space-forming member 10 that can be deformed to change the pressure of the internal space SP is provided with a detection unit 20 that can detect pressure changes corresponding to its deformation and is arranged outside the prescribed space. Therefore, in the toy 1 that performs actions based on pressure changes detected by the detection unit 20, even if it does not have a high degree of airtightness of the pressure P in the prescribed space, it is easy to detect the pressure changes corresponding to the deformation of the space-forming member 10, and a toy 1 with stable performance can be provided.

[0151] In the toy 1 of this embodiment, the detection unit 20 includes the displacement unit 23 that changes position according to a pressure change. Therefore, the position displacement can be easily converted into an electrical signal by the pressure sensor 25 .

[0152] Furthermore, the displacement portion 23 is always urged in a direction away from the pressure sensor 25 , so that the on / off operation of the pressure sensor 25 in conjunction with the deformation of the space forming member 10 can be accurately and reliably binarized.

[0153] In the toy 1 of this form, the space forming member 10 includes the first sheet member 11 and the second sheet member 12 having different elastic deformation amounts, so that, for example, the elastic deformation amount of the sheet member with a smaller elastic deformation amount can be amplified by the sheet member with a larger elastic deformation amount. Thus, a smaller action can be reliably selected as a larger action.

[0154] In particular, the outer shell of the toy 1 is formed by using the second sheet member 12 with a small elastic deformation amount, and the first sheet member 11 with a large elastic deformation amount is provided on the side where the pressure sensor 25 is pressed, so that it is possible to accurately extract a small change in the outer shell of the toy 1. As a result, it is easy to classify the intensity of the pressing operation into multiple levels, and it is possible to provide a toy 1 that produces a wide range of scales.

[0155] In the toy 1 of the present embodiment, the pressure sensor 25 is accommodated and held in the accommodation member 15 that does not elastically deform, so that the detection function of the detection unit 20 can be made accurate.

[0156] In the toy 1 of this embodiment, by setting the structure in which the thickness of the first sheet member 11 is thinner than the thickness of the second sheet member 12, it is possible to form members with different deformation amounts using the same material.

[0157] In the toy 1 of this embodiment, the sealing portion where the second sheet member 12 is attached to the housing member 15 by strongly fastening the holding member 30 is formed into a multi-layer structure in which a plurality of sheets are arranged in an overlapping manner, so that the sealing property can be ensured.

[0158] Furthermore, since the fastening member 50 fastening and fixing the second sheet member 12 is configured to be attached from the rear side of the character of the toy 1 , the structure of the attachment portion cannot be seen when the character is viewed from the front, and the appearance can be well maintained.

[0159] In the toy 1 of this form, the bottom surface side of the toy 1 is constituted by a hard storage member 15, and its size is constituted to be substantially the same as the bottom surface size of the second sheet member 12 that can be pressed, so it can be stably placed on the mounting surface 60. In addition, when the second sheet member 12 is pressed, the entire bottom surface side is constituted by a hard material, so that the force of the pressing operation can be stably received, and the operability can be improved.

[0160] According to the toy of this form, the regulating valve 40 for regulating the pressure of the internal space SP can cope with changes in atmospheric pressure. For example, the bulging state of the second sheet member 12 can be maintained substantially equal to the atmospheric pressure. Therefore, no special pressurizing component is required, and the structure can be simplified.

[0161] In addition, as a structure for operating the valve portion 41 that opens and closes the air hole 46, the regulating valve 40 uses a force point member 45 having a force point portion 42 and a fulcrum portion 43 across the valve portion 41, thereby improving the reliability of the closed state of the valve portion 41 and accurately adjusting the operation of the open state. Furthermore, the valve portion 41 is configured so that only the force point portion 42 of the valve portion 41 can be inserted from the outer cover 15d, thereby ensuring the ease of adjustment and protecting the regulating valve 40.

[0162] In the above, one form of the technology disclosed in the present invention is described, but the technology disclosed in the present invention can be appropriately changed within the scope of its technical concept. For example, in the above form, the action part is set to perform an action in a manner of linearly changing its position based on the pressure change detected by the detection unit 20, but the structure of the action part is not limited to this, for example, it can also be a structure that performs a rotational action, or an electronic variable action.

[0163] In addition, in the above-mentioned form, the pressure change of the internal space SP is changed into sound, but it is not limited to this. It can also be a structure that can perform a luminous performance by changing the intensity of light, or a structure that can perform a color performance by changing the color.

[0164] In addition, in the structure of the above-mentioned form, the pressure medium in the internal space SP is air, but it is not limited to air and may be liquid such as water.
