DETAILED DESCRIPTION
[0041] Figure 1 is a view showing a front profile of the human-shaped toy 2 in an upright posture and the arrangement of the joint member, which is an example of the present embodiment. In addition, the profile is shown by a broken line.
[0042] The human-shaped toy 2 is a toy that reproduces a character based on a comic, an animation, a special effect movie, a game, a novel, or the like as a three-dimensional shaped object. The human-shaped toy 2 of the present embodiment has a design that imitates a human-shaped robot weapon equipped with an armed prop 4. The human-shaped toy 2 is a so-called plastic model, which is a toy that is completed by a user cutting out members from an injection kit and assembling them.
[0043] The human-shaped toy 2 has a plurality of movable portions, and at one or more positions of the movable portions, a plurality of members are used as a joint member 6 whose relative angle is variable. Where several joint members 6 are used can be appropriately set according to the design of the human-shaped toy 2. In the example of Figure 1 In the example, the joint member 6 is used at the elbow joints of both arms, the knee joints of both legs, and the six armed props 4 as a part of the built-in frame, respectively. Of course, according to the design of the human-shaped toy 2, the joint member 6 can also be a member that is visible from the outside.
[0044] Figure 2is a view showing an example of an injection kit 8 that links the parts 6. The injection kit 8 is included in the package of the figurine toy 2. In the injection kit 8, a plurality of the linking parts 6 are integrally formed by a gate, a runner. The injection kit 8 is made using a plurality of kinds of synthetic resin materials that constitute the linking parts 6 and by a molding process in one or more times.
[0045] Figure 3 is a front view of the linking part 6. Figure 4 is a plan view of the linking part 6. Figure 5 is a bottom view of the linking part 6. The three orthogonal axes in the drawing including Figures 3 to 5 the front direction as the positive direction of the Z axis, the right direction as the positive direction of the X axis as viewed from the front positive direction, and the upper direction as the positive direction of the Y axis as viewed from the front positive direction.
[0046] The linking part 6 is a movable part that connects three linking target parts 9 (9a, 9b,...) in a relative attitude and a relative position. The linking part 6 is configured by connecting two shaft parts 10 (a first shaft part 10a, a second shaft part 10b), two bearing parts 20 (a first bearing part 20a, a second bearing part 20b), and one intermediate part 30 in a straight line. As for the connection order, the first shaft part 10a, the first bearing part 20a, the intermediate part 30, the second bearing part 20b, and the second shaft part 10b are sequentially connected from the left side when viewed toward the front.
[0047] The shaft parts 10, i.e., the first shaft part 10a and the second shaft part 10b, are identical components that are connected in different positions and attitudes.
[0048] The bearing parts 20, i.e., the first bearing part 20a and the second bearing part 20b, are identical components that are connected in different positions and attitudes.
[0049] Further, the linking part 6 is designed so that an axis line formed by the first shaft part 10a and the first bearing part 20a is parallel to an axis line formed by the second bearing part 20b and the second shaft part 10b. Of course, a design in which the axis lines intersect can also be adopted.
[0050] Figure 6 is a perspective view of the shaft part 10.
[0051] The shaft part 10 is a unitary structure having a shaft portion 11, a claw portion 13, an arm portion 15, and a mounting portion 17. The shaft part 10 is composed of the same first resin material (for example, ABS (acrylonitrile butadiene styrene resin) that is a resin having a higher hardness than the second resin material) and is molded by first injection when the injection kit 8 is manufactured.
[0052] The mounting portion 17 is a portion for mounting a component to be coupled to the shaft component 10 (in the example, a first coupling target component 9a to be coupled to the first shaft component 10a, and a second coupling target component 9b to be coupled to the second shaft component 10b). Figure 3 In the example, the mounting portion 17 is exemplified as a structure in which a hole is provided in a plate-shaped portion, but can be other shapes. Figure 6 In the example, the mounting portion 17 is exemplified as a structure in which a hole is provided in a plate-shaped portion, but can be other shapes.
[0053] A pair of arm portions 15 is provided extending toward the right side from the end portions of the mounting portion 17 on both the front side and the back side, and a cylindrical shaft portion 11 is formed between the pair of arm portions 15 in the front-back direction (Z-axis direction).
[0054] Further, a claw portion 13 is provided on the side surface of the mounting portion 17 opposite the shaft portion 11 with the tip end facing the shaft portion 11.
[0055] The claw portion 13 is a first engagement portion provided facing the shaft portion 11, and has a linear tip end parallel to the shaft direction of the shaft portion 11. Specifically, the tip end shape of the claw portion 13 is wedge-shaped when viewed from the XY cross section, becoming thinner toward the shaft portion 11, and is linear parallel to the Z-axis direction (or substantially parallel within a range including errors). A space is provided between the shaft portion 11 and the claw portion 13 in which the thickness portion of the cylinder of the cylindrical portion 21 of the bearing component 20 is to be located.
[0056] Further, a movable range restriction surface 16 is formed on the side surface of the right side of the arm portion 15, and abuts against the side surface in the X-axis direction of the first movable range restriction portion 26 (refer to Figure 7 ) of the bearing component 20 described later, and functions to restrict the movable range of the shaft rotation between the shaft component 10 and the bearing component 20 (specifically, the range of the mounting portion 17 of the shaft component 10 swinging upward with respect to the shaft portion 11).
[0057] Figure 7 is a perspective view of the bearing component 20.
[0058] The bearing component 20 is a unitary structure having two cylindrical portions 21 (21a, 21b), groove portions 22 (22a, 22b, 22c), a large diameter portion 23, a first movable range restriction portion 26, and a second movable range restriction portion 27. The bearing component 20 is formed of a second resin material (for example, a PP (polypropylene) resin: a resin having a lower hardness than the first resin material) having a different hardness from the first resin material, and is formed by second injection when manufacturing the injection kit 8.
[0059] The two cylindrical portions 21 (first cylindrical portion 21a, second cylindrical portion 21b) are substantially cylindrical bodies provided at positions on the outer side of the shaft portion 11 of the shaft member 10, sandwiched by the pair of arm portions 15 at both ends. A plurality of groove portions 22 (22a, 22b,...) capable of engaging with the claw portion 13 of the shaft member 10 are formed on the outer peripheral surface of the cylindrical portion 21 (first cylindrical portion 21a, second cylindrical portion 21b). Furthermore, the axes of the cylinders of the two cylindrical portions 21 are set to be parallel.
[0060] The groove portion 22 is a second engaging portion capable of engaging with the claw portion 13 (first engaging portion), and is set to be parallel to the axial direction of the shaft portion 11 (substantially parallel including within a range including an error).
[0061] Specifically, a movable range Am of a range of the same radius is set on the outer peripheral surface of the cylindrical portion 21, and the groove portion 22 of the V-shaped groove is formed in the movable range Am. Specifically, a total of three groove portions 22 (22a, 22b, 22c) at both ends and in the middle of the movable range Am are formed. In addition, in the state of the injection sleeve 8 (refer to FIG. 2), one of the side surfaces of the groove portion 22c in which the groove is formed, which becomes a state of engaging with the claw portion 13, is used as a plane constituting a large diameter portion 23 having a larger radius than the radius of the movable range Am. Figure 2
[0062] The first movable range restriction portion 26 is a protruding portion formed in the axial direction (front and back direction: Z-axis direction) of the cylinder of the cylindrical portion 21 from the middle position of the two cylindrical portions 21. The first movable range restriction portion 26 abuts against the arm portion 15 of the shaft member 10, thereby restricting the relative rotation range of the shaft member 10 and the bearing member 20 about the shaft portion 11 as the center. Specifically, it functions to restrict the upward (Y-axis positive direction) swinging movement of the mounting portion 17 with respect to the shaft portion 11.
[0063] The second movable range restriction portion 27 is a convex portion formed in the downward (Y-axis negative direction) direction from the lower surface of the bearing member 20. The left and right side surfaces of the second movable range restriction portion 27 abut against the web portion (lower surface) of the claw portion 13 of the shaft member 10, thereby functioning to restrict the downward swinging movement of the mounting portion 17 with respect to the shaft portion 11.
[0064] The first cylindrical portion 21a of the first bearing member 20a is a portion corresponding to the shaft portion 11 of the first shaft member 10a. The second cylindrical portion 21b of the first bearing member 20a is a portion corresponding to the first shaft portion 31a of the intermediate member 30 (refer to FIG. 3). Figure 8 Furthermore, the first cylindrical portion 21a of the second bearing member 20b is a portion corresponding to the shaft portion 11 of the second shaft member 10b. The second cylindrical portion 21b of the second bearing member 20b is a portion corresponding to the second shaft portion 31b of the intermediate member 30.
[0065] Figure 8 is an elevation view of the intermediate part 30.
[0066] The intermediate part 30 is a part that connects the first bearing part 20a and the second bearing part 20b and serves to mount the third joint target part 9c (refer to Figure 3 ).
[0067] The intermediate part 30 is a unitary structure having two shaft portions 31 (31a, 31b), two claw portions 33 (33a, 33b), an arm portion 35, and a mounting portion 37. The intermediate part 30 is composed of the same first resin material (for example, ABS resin: higher in hardness than the second resin material) and is formed by first injection when manufacturing the injection set 8.
[0068] The mounting portion 37 is a site for mounting a part to be joined to the intermediate part 30 (in the example of Figure 3 , the third joint target part 9c). Here, the mounting portion 37 is exemplified as a hollow box that protrudes upward on the upper surface of the plate portion, but can be other shapes.
[0069] Further, a pair of arm portions 35 is provided so as to extend toward the left and right from the end portions of the mounting portion 37 on both the front side (Z-axis positive direction side) and the back side (Z-axis negative direction side), and a cylindrical shaft portion 31 is formed between each pair of arm portions 35 in the front-back direction.
[0070] The first shaft portion 31a of the two shaft portions 31 is a site corresponding to the second cylindrical portion 21b of the first bearing part 20a. The second shaft portion 31b is a site corresponding to the second cylindrical portion 21b of the second bearing part 20b. Further, the shaft directions of both the first shaft portion 31a and the second shaft portion 31b are parallel to each other (including substantially parallel within a range including errors).
[0071] Further, with respect to the first shaft portion 31a and the second shaft portion 31b, the first claw portion 33a and the second claw portion 33b are provided on the side surfaces of the mounting portion 37 opposite to the shaft portions in a manner that the tip ends thereof face the shaft portions 31. The tip end shapes are wedge-shaped when viewed from the XY cross section, in which the tip ends become thinner as they face the shaft portions 31 to which they correspond. There is a space between the shaft portions 31 and the claw portions 33 in which the thickness of the cylinder of the cylindrical portion 21 of the bearing part 20 is located.
[0072] Conversely, when the entire joint part 6 is viewed (refer to Figures 3 to 5), the 1st shaft part 10a, the 1st bearing part 20a, the intermediate part 30, the 2nd bearing part 20b, and the 2nd shaft part 10b are formed in a straight line in this order, as a result, the rotation axes formed of the shafts and the bearings of the connecting part 6 are set to be all parallel (approximately parallel within a range including errors).
[0073] Furthermore, as described, the shaft part 10 and the intermediate part 30 are produced by the first injection molding using the 1st resin material, and the bearing part 20 is produced by the second injection molding using the 2nd resin material. Thus, in essence, the shaft part 10 and the intermediate part 30 produced by the first injection molding function as insert parts for insert molding (meaning that a part is integrally molded by a subsequent molding process that produces a different part from the part produced by the molding process of the previous process) in the second injection molding.
[0074] Figure 9 is an enlarged sectional view of the vicinity of the connecting part between the 1st shaft part 10a and the 1st bearing part 20a, and is a sectional view in the state of the injection set 8. The sectional view is an XY sectional view.
[0075] In the connecting part 6 of the injection set 8 (refer to Figure 2 ), the cylindrical part 21 of the bearing part 20 is formed outside the shaft part 11 of the shaft part 10. Similarly, the cylindrical part 21 of the bearing part 20 is also formed outside the shaft part 31 of the intermediate part 30. Further, the arm part 15 and the arm part 35 are formed at the shaft end of the shaft part 11 and the shaft end of the shaft part 31, respectively. Furthermore, in the state of the injection set 8, the connecting part 6 is formed in a state in which the claw part 13 of the 1st shaft part 10a is engaged with the groove part 22c of the 1st bearing part 20a.
[0076] In addition, the relationship around the connecting part between the 2nd shaft part 10b and the 2nd bearing part 20b is the same as that of Figure 9 by reversing the left-right direction, and thus the description is omitted.
[0077] Furthermore, even if the user attempts to rotate the 1st shaft part 10a around the shaft part 11 in the clockwise direction from the state of Figure 9 , rotation in the clockwise direction is not possible due to the abutment of the side surface (refer to Figure 7 ) of the 1st movable range limiting part 26 of the 1st bearing part 20a in the X-axis direction and the side surface (movable range limiting surface 16; refer to Figure 6 ) of the arm part 15 of the 1st shaft part 10a (refer to Figure 3). Furthermore, the large-diameter portion 23 exists on the clockwise direction side of the groove portion 22c, and therefore, even if an attempt is made to rotate the first shaft member 10a around the shaft portion 11 in the clockwise direction, the rotation is still not possible due to the abutment of the upper surface of the claw portion 13 against the large-diameter portion 23.
[0078] Conversely, if the user attempts to rotate the first shaft member 10a around the shaft portion 11 in the counterclockwise direction, the claw portion 13 needs to pass over the groove of the groove portion 22c, and therefore, the user is able to feel a reliable sense of operation. Conversely, Figure 9 the state is reliably maintained.
[0079] When the claw portion 13 passes over the groove of the groove portion 22c, the claw portion 13 slides in contact with the outer peripheral surface of the movable range Am (refer to Figure 7 ) while moving toward the adjacent groove portion 22b. At this time, since the first resin material of the first shaft member 10a is harder than the second resin material of the first bearing member 20a, the claw portion 13 substantially maintains the wedge-shaped tip shape, and slides in contact with the outer peripheral surface of the movable range Am while flexing the outer peripheral surface of the movable range Am.
[0080] When the claw portion 13 reaches the adjacent groove portion 22b, the tip of the claw portion 13 is embedded in the groove portion. At this time, since the sliding contact resistance between the claw portion 13 and the outer peripheral surface of the movable range Am disappears instantaneously, a moderate click feeling that the claw portion 13 has reached the next groove portion is conveyed to the user. Furthermore, by completing the embedding, the claw portion 13 and the adjacent groove portion 22b are reliably held this time.
[0081] Figure 10 is an enlarged sectional view of the connection portion between the intermediate member 30 and the first bearing member 20a, and is a sectional view in the state of the injection molding set 8. The sectional view is an XY sectional view.
[0082] In the link member 6 of the injection molding set 8, the second cylindrical portion 21b of the first bearing member 20a is formed on the outside of the first shaft portion 31a of the intermediate member 30. Furthermore, the arm portion 35 is formed on the shaft end of the first shaft portion 31a. Furthermore, in the state of the injection molding set 8, the link member 6 is formed in a state in which the first claw portion 33a of the intermediate member 30 is engaged with the groove portion 22c of the second cylindrical portion 21b of the first bearing member 20a.
[0083] In addition, the relationship around the connection portion between the second shaft portion 31b of the intermediate member 30 and the second cylindrical portion 21b of the second bearing member 20b is the same as Figure 10 , by merely reversing the left-right direction, and therefore, the explanation is omitted.
[0084] Further, around the connection portion between the intermediate member 30 and the first bearing member 20a and around the connection portion between the intermediate member 30 and the second bearing member 20b, the same effects as those of the connection portion between the first shaft member 10a and the intermediate member 30 are exerted. That is, the movable range is limited, the click feeling at the time of operation is imparted, the engaged state between the claw portion 33 and the groove portion 22 is reliably maintained, and the like. Figure 9 As explained the same, the effects of limiting the movable range, imparting the click feeling at the time of operation, reliably maintaining the engaged state between the claw portion 33 and the groove portion 22, and the like are exerted. In addition, it is preferable that the claw portion 33 be constituted of the first resin material having a higher hardness than the second resin material constituting the groove portion 22, so that the holding force and the durability are improved.
[0085] Next, an example of the use mode of the linking member 6 will be explained.
[0086] Figure 11 is a front view of the first use mode of the linking member 6, and includes a partial enlarged view showing an example of the engaged positional relationship between the claw portion 13 of the first shaft member 10a and the groove portion 22 of the first bearing member 20a in this use mode. Figure 12 An example is shown in which the linking member 6 of the armament 4 is in the first use mode.
[0087] The linking member 6 in the state of the injection kit 8 has a linear appearance as a whole when viewed from the front. The armament 4 has three outer members which are roughly divided into a first outer member 41, a second outer member 42, and a third outer member 43. The first outer member 41 is a first linking target member 9a (see Figure 3 ) with respect to the armament 4, and is attached to the attachment portion 17 of the first shaft member 10a. The second outer member 42 is a second linking target member 9b (see Figure 3 ) with respect to the armament 4, and is attached to the attachment portion 17 of the second shaft member 10b. The third outer member 43 is a third linking target member 9c (see Figure 3 ) with respect to the armament 4, and is attached to the attachment portion 37 of the intermediate member 30. Thus, since the linking member 6 is in the first use mode, the armament 4 becomes a linear style.
[0088] Figure 13 is a front view of the second use mode of the linking member 6, and includes a partial enlarged view showing an example of the engaged positional relationship between the claw portion 13 of the first shaft member 10a and the groove portion 22 of the first bearing member 20a in this use mode. Figure 14 An example is shown in which the linking member 6 of the armament 4 is in the second use mode.
[0089] In the second use mode, the claw portion 13 of the first shaft member 10a engages with the middle groove portion 22b of the three groove portions 22 of the first cylindrical portion 21a of the first bearing member 20a. Further, the first claw portion 33a of the intermediate member 30 engages with the middle groove portion 22b of the three groove portions 22 of the second cylindrical portion 21b of the first bearing member 20a, and the second claw portion 33b engages with the middle groove portion 22b of the second cylindrical portion 21b of the second bearing member 20b. Also, the claw portion 13 of the second shaft member 10b engages with the middle groove portion 22b of the first cylindrical portion 21a of the second bearing member 20b.
[0090] Thus, when the coupling member 6 is viewed from the front, the coupling member 6 has a shape of a curved shape at both ends opening on the back side. Since the coupling member 6 is in the second use mode, as shown in FIG. 6, the weapon 4 has a style of a curved shape at both ends. Figure 14
[0091] Figure 15 is a front view of the third use mode of the coupling member 6, and includes a partial enlarged view showing an example of the engagement positional relationship between the second claw portion 33b of the intermediate member 30 and the groove portion 22 of the second cylindrical portion 21b of the second bearing member 20b, and the engagement positional relationship between the claw portion 13 of the second shaft member 10b and the groove portion 22 of the first cylindrical portion 21a of the second bearing member 20b in this use mode. Figure 16 An example is shown in which the coupling member 6 of the weapon 4 is in the third use mode.
[0092] In the third use mode, the relative position and the relative attitude between the first shaft member 10a and the first bearing member 20a are the same as in the first use mode. Further, the relative position and the relative attitude between the first bearing member 20a and the intermediate member 30 are also the same as in the first use mode.
[0093] On the other hand, on the right side of the intermediate member 30, the second claw portion 33b engages with the groove portion 22a on the lowermost surface side of the second cylindrical portion 21b of the second bearing member 20b. Also, the claw portion 13 of the second shaft member 10b engages with the groove portion 22a of the first cylindrical portion 21a of the second bearing member 20b.
[0094] Thus, when the coupling member 6 is viewed from the front, the left side centered on the intermediate member 30 has a straight line shape, and the right side has a folded shape. Since the coupling member 6 is in the third use mode, as shown in FIG. 8, the weapon 4 has a style of the first outer member 41 and the third outer member 43 arranged in a straight line, with the second outer member 42 attached to the back. Figure 16
[0095] According to the present embodiment, the shaft part 10 and the intermediate part 30 are molded by the first injection molding, and the bearing part 20 is molded by the insert molding using the shaft part 10 and the intermediate part 30 as the insert parts, whereby the joined part 6 in a state in which the shaft part 10, the intermediate part 30, and the bearing part 20 are joined in advance is provided in the form of the injection set 8. The user can cut out the joined part 6 from the gate, and does not need to spend the effort of assembling the joined part 6 itself. In the case in which a plurality of joined parts 6 having the same configuration are needed, the assembly work can be omitted, and this is a more useful point of the present embodiment. Further, in the stage of molding as described above, the joined part 6 itself is provided in a state of excellent precision compared with the case in which the user assembles the joined part 6, in a state in which the shaft part 10, the intermediate part 30, and the bearing part 20 are joined in advance. More specifically, the amount of engagement of the claw part and the groove part of each joined part 6 is less likely to be shifted, and thus the joined part 6 can be provided in a state in which the set provider can easily exert the desired holding force using the engagement of the claw part and the groove part. Further, with the joined part 6, the relative positional relationship between the joined parts can be held more reliably than in the past.
[0096] In addition, the embodiment to which the present application can be applied is not limited to the examples described above, and the constituent elements can be appropriately added, omitted, or changed without changing the gist of the application.
[0097] For example, the shape of the toy using the joined part 6 is not limited to the examples of the human-shaped toy 2 and the weapon 4. As long as the toy has a movable part, the joined part 6 can be applied equally.
[0098] Further, with respect to any one or all of 1) the concave-convex relationship between the claw part 13 and the groove part 22, 2) the concave-convex relationship between the first claw part 33a and the groove part 22, and 3) the concave-convex relationship between the second claw part 33b and the groove part 22 in the joined part 6, the structure in which the side that is convex and the side that is concave in the concave-convex relationship are reversed can also be used. In other words, the structure in which the first engagement part of the shaft part 10 is a groove part and the second engagement part of the bearing part 20 is a claw part can also be used. Further, the order of the injection molding can also be appropriately changed. For example, the bearing part 20 can be molded by the first injection molding using the first resin material, and the shaft part 10 and the intermediate part 30 can be molded by the second injection molding using the second resin material.
[0099] Further, in the above embodiment, the link member 6 is exemplified as a four-joint movable member, but can also be configured as a two-joint movable member. Specifically, a structure can also be adopted in which the intermediate member 30 and the second bearing member 20b are omitted from the link member 6 of the above embodiment, and the shaft portion 11 of the second shaft member 10b is engaged with the second cylindrical portion 21b of the first bearing member 20a.
[0100] Further, the link member 6 can also be formed as a single-joint movable member. Specifically, the intermediate member 30, the second bearing member 20b, and the second shaft member 10b are omitted from the link member 6 of the above embodiment. Further, a structure can also be adopted in which the second cylindrical portion 21b of the first bearing member 20a of the above embodiment is replaced with the mounting portion 17.
