[0014] Hereinafter, a crane toy according to an embodiment of the present invention will be described with reference to the drawings.

[0015] Overview of Crane Toy 100 FIG. 1 is a perspective view of a toy crane 100, and FIG. 2 is a perspective view of the toy crane 100 as seen from behind. The crane toy 100 has a storage section 21 formed in the device body 20 for the items 10 to be captured. The items 10 can be loaded into the device body 20 through an inlet 22 (Fig. 2) at the rear right side. The loaded items 10 are stored in the storage section 21, which is formed in an arc shape so as to bulge forward when viewed from above. This storage section 21 can store multiple items 10. The storage section 21 is partitioned by a transparent plate 23 with a curved front. The device body 20 has a discharge outlet 24 formed in the upper left of the storage section 21. The discharge outlet 24 is connected to a slope 25 on the outside of the device body 20.

[0016] The device main body 20 is provided with a capture device 50 above the storage section 21. The capture device 50 moves left and right depending on the direction of rotation by rotating the handle wheel 26 on the right front of the device main body 20. The capture device 50 also moves up and down depending on the direction of operation by operating the operating lever 27 on the left front of the device main body 20. When the capture device 50 is lowered, it can automatically capture an item 10 if it is located below. After capturing the item 10, the operating lever 27 is operated to raise the capture device 50, and then the handle wheel 26 is rotated to transport the item 10 to the discharge outlet 24. The capture device 50 then releases the captured item 10. The released item 10 is then discharged forward down the slope 25.

[0017] 《Article 10》 The article 10 is an ellipsoid. For example, the article 10 is a capsule formed by joining two half shells together, and contains a small item.

[0018] <Device body 20> <Cylinder 30> FIG. 3 is a perspective view of the cylindrical body 30, and FIG. 4 is a view showing the inside of the cylindrical body 30. As shown in FIG. A hollow cylindrical body 30 is provided in the housing of the device main body 20 so as to be rotatable about a vertical axis. This cylindrical body 30 is configured to be rotated within a predetermined angular range about the vertical axis by a first operating device 60, which will be described later. A slit 31 extending in the vertical direction is formed in the cylindrical body 30. A support body 32 is also provided on the cylindrical body 30.

[0019] <Support 32> The support 32 is provided so as to protrude radially outward from the cylindrical body 30. The support 32 is attached to the cylindrical body 30 so as to be able to move up and down, and supports a capturing device 50, which will be described later. The support 32 is composed of a first support portion 32a attached to the cylindrical body 30 and a second support portion 32b attached to the first support portion 32a and supporting the capturing device 50.

[0020] As shown in Fig. 4, the first support portion 32a extends through the slit 31 from the inside to the outside of the cylindrical body 30. The first support portion 32a is fixed to the upper end (one end) of the rack belt 33 inside the cylindrical body 30. The rack belt 33 is flexible and can be moved up and down along a rail 34 by a second operating device 70 described below. The up and down movement of the rack belt 33 causes the first support portion 32a to rise and fall along the slit 31. The other end of the rack belt 33 is free, folded back by a gear 72h described below, and movably engaged with a rail (not shown). The first support portion 32a is provided with pinions 35a and 35b having a central axis in the extension direction of the first support portion 32a. The pinions 35a and 35b are meshed with fixed racks 36a and 36b that are provided inside the cylindrical body 30 and extend in the vertical direction. When the first support portion 32a is raised or lowered, the pinions 35a and 35b roll on the fixed racks 36a and 36b.

[0021] The second support portion 32b is connected to the first support portion 32a via a horizontally extending shaft 37. The second support portion 32b is configured to be movable up and down within a predetermined range around the shaft 37, and can take an upper position and a lower position. The second support portion 32b is biased toward the upper position by a torsion spring 37a (see FIG. 6). The upper position is the normal position of the second support portion 32b. The second support portion 32b is formed with a sliding contact portion 38 formed of an inclined surface. Meanwhile, as shown in Fig. 5, the back plate 39 that separates the storage portion 21 is provided with an abutted portion 39a near the discharge outlet 24. The abutted portion 39a is an inclined surface, although this is not particularly limited. Then, when the capture device 50 described below reaches the discharge outlet 24, the inclined surface 38 abuts against the abutted portion 39a, and the second support portion 32b moves downward relative to the first support portion 32a. In addition, a capturing device 50 is attached to the second support portion 32b.

[0022] <Capturing device 50> FIG. 6 is a perspective view of the capture device 50, and FIG. 7 is a perspective view of the capture device as seen from below. The capturing device 50 captures the article 10 . In this embodiment, the capturing device 50 has a pair of arms 51a, 51b and an abutment piece 52, and is configured to embrace and capture the item 10 through cooperation between the pair of arms 51a, 51b and the abutment piece 52.

[0023] The pair of arms 51a, 51b are attached to the second support part 32b so as to be rotatable around an axis 52a extending in the radial direction of the cylindrical body 30. The pair of arms 51a, 51b can be in a closed position and an open position. The pair of arms 51a, 51b are biased toward the closed position by a torsion spring 52b. This closed position is the normal position of the pair of arms 51a, 51b. When the support body 32 moves downward, the tips of the pair of arms 51a, 51b come into contact with the article 10 and slide open, and when they move further downward, they cooperate with the abutment piece 52 to hold and capture the article 10, as shown in FIG. 8.

[0024] The main body portions of the pair of arms 51a, 51b hang down vertically, and their tip ends are bent at an obtuse angle in a direction in which they approach each other (inward). A predetermined gap is normally formed between the tip ends of the pair of arms 51a, 51b. Meanwhile, the base end portions of the pair of arms 51a, 51b are bent inward relative to the main body portions and are pivotally supported by the second support portion 32b via a shaft 52a. The base end portions of the pair of arms 51a, 51b extend rearward along the support body 32 in a manner that does not interfere with the opening and closing of the pair of arms 51a, 51b, and as shown in FIG. 9, surround the second support portion 32b on all sides. Operation pieces 53a, 53b are formed at the rear ends of these base end portions. The distance between the operation pieces 53a, 53b is smaller than the diameter of the cylindrical body 30. When the second support portion 32b rotates downward relative to the first support portion 32a, the operation pieces 53a, 53b slide against the outer surface (sliding contact portion) of the cylindrical body 30 and move in directions that separate them, causing the pair of arms 51a, 51b to open and release the captured article 10. In other words, the cylindrical body 30 intervenes between the operation pieces 53a, 53b, causing the operation pieces 53a, 53b to move in directions that separate them, releasing the captured article 10.

[0025] The contact piece 52 is fixed to the lower side of the second support portion 32b. As shown in FIG. 8, the pair of arms 51a, 51b and the abutting piece 52 cooperate to hold and capture the article 10.

[0026] <First operating device 60> FIG. 10 is a perspective view of the first operating device 60. As shown in FIG. The first operating device 60 rotates the cylindrical rotor and thus the support body by human power. The first operating device 60 includes a handwheel 26 as an input unit and a gear train 61 that transmits the power of the handwheel 26 to the cylindrical rotor.

[0027] The first operating device 60 transmits power generated in the gear 61a by the rotation of the handwheel 26 via gears 61b, 61c, 61d, 61e, and 61f to a partial gear 61g formed on the outer periphery of the bottom of the cylindrical body 30. This causes the cylindrical body 30 to rotate in a direction corresponding to the rotation direction of the handwheel 26.

[0028] <Second operating device 70> FIG. 11 is a perspective view of the first operating device 60. As shown in FIG. The second operating device 70 uses a battery-powered motor to move the support 32 up and down. The second operating device 70 includes a motor 71 and a gear train 72 that rotate integrally with the cylindrical body 30.

[0029] The second operating device 70 transmits the power of a motor 71 to the rack belt 33 via gears 72a, 72b, 72c, 72d, 72e, 72f, 72g, and 72h. Of these, gears 72d and 72e are double gears in which a large diameter gear and a small diameter gear are integrated. The large diameter gear of gear 72d meshes with gear 72c, and the small diameter gear meshes with the large diameter gear of gear 72e. Furthermore, the small diameter gear of gear 72e meshes with gear 72f.

[0030] Effects of the embodiment According to the crane toy 100 configured as described above, when the pair of arms 51a, 51b that have captured the item 10 reach the discharge outlet 24, the second support portion 32b moves downward, causing the operating pieces 53a, 53b to slide against the outer surface of the cylindrical body 30, and the operating pieces 53a, 53b move away from each other, opening the pair of arms 51a, 51b.

[0031] <<Variation>> The toy crane 100 according to the embodiment of the present invention has been described above, but the present invention is not limited to a stationary toy crane, and can also be applied to a toy crane mounted on a toy car.

[0032] Furthermore, in the above embodiment, the article 10 is described as being an ellipsoid, but it may be a sphere or other shape.

[0033] Furthermore, the above-mentioned capturing device 50 is configured to hold the article 10 with the pair of arms 51a, 51b and the abutment piece 52, but it may also be configured to hold the article with only the pair of arms.

[0034] Furthermore, in the above embodiment, a case has been described in which the pair of arms 51a, 51b are moved horizontally and up and down, but the present invention can also be applied to a case in which the pair of arms 51a, 51b are configured to only move up and down, an outlet is provided in the cylindrical body 30, and the pair of arms 51a, 51b move upward to cause the second support part 32b to abut against a contact part, thereby releasing the item 10 into the outlet.

[0035] Furthermore, in the above embodiment, the pair of arms 51a, 51b rotate together with the cylindrical body 30, and the pair of arms 51a, 51b are opened by sliding the operating pieces 53a, 53b against the outer periphery (sliding portion) of the cylindrical body 30. However, the pair of arms 51a, 51b may be opened by sliding the operating pieces 53a, 53b against a wall that is fixed near the release location, without providing the cylindrical body 30.
