Description

[Technical field]

[0001] The present invention relates to a parts connection structure for a doll toy. [Background technology]

[0002] For assembly toys with movable parts, a structure that connects parts that can be stretched, contracted, or bent is essential. For example, the doll toy disclosed in Patent Document 1 has a part connecting structure that consists of a one-piece upper knee part and a two-piece lower knee part divided into left and right parts.

[0003] Specifically, the upper knee corresponds to an internal skeleton above the knee of a doll toy, and the tip of the rod-shaped main body on the lower knee side is spherical, and the spherical part has a linear groove. The two pieces of the lower knee each have a linear convex part on the inner side facing each other when assembled, which engages with the linear groove of the upper knee to guide it in the extension / retraction direction. The legs of the doll toy are assembled by sandwiching the upper knee between the two pieces of the lower knee. The upper knee is extended by sliding it up from the lower knee, and when it is slid all the way, the linear groove and the linear convex part are released from engagement, and the spherical part of the upper knee is held freely rotatable within the two pieces of the lower knee. In other words, when the upper knee is fully extended from the lower knee, it can be bent as the knee of a leg. [Prior art documents] [Patent documents]

[Figure 9] 13 is a perspective view for explaining assembly of the auxiliary arm and its extension and retraction operation. FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Fig. 1 is a front external view showing a configuration example of a doll toy 2 which is an example of an embodiment to which the present invention is applied. The doll toy 2 is an assembly toy, a so-called plastic model, which reproduces characters appearing in original works such as manga, anime, special effects movies, games, and novels as three-dimensional objects. In the example of Fig. 1, the doll toy 2 has a design imitating a humanoid robot weapon with an armored warrior as its motif, and is a doll body made by assembling parts for each body part.

[0020] The doll toy 2 is designed so that an external part (for example, offensive armament, defensive armament, etc.) can be attached interchangeably to an internal frame that corresponds to the skeleton and muscles of a human. In other words, it is designed as a doll body that can be partially dressed up. The doll toy 2 has movable structures in various parts so that it can take poses similar to those of a human.

[0021] The doll toy 2 is designed to be equipped with a weapon 4. The example of the weapon 4 shown in Fig. 1 is designed to resemble a large heavy artillery gun. The doll toy 2 is provided with an auxiliary arm 10 for holding the large weapon 4.

[0022] The auxiliary arm 10 is designed to resemble a robot arm that can expand and contract and bend to assist the arm strength of the doll body of the doll toy 2. The auxiliary arm 10 is thin in appearance, but is designed to provide sufficient auxiliary strength. In this embodiment, the auxiliary arm 10 has a parts-connected structure.

[0023] Fig. 2 is a perspective view showing an example of a usage state of the auxiliary arm 10 (parts connection structure). Fig. 3 is a perspective external view showing an example of a contracted limit state of the auxiliary arm 10. Fig. 4 is a perspective external view showing an example of an extended limit state of the auxiliary arm 10.

[0024] In addition, in Fig. 2 and subsequent figures, three orthogonal axes indicating reference directions for the auxiliary arm 10 are attached. The three orthogonal axes are right-handed coordinates, with the X-axis direction indicating the extension and contraction direction and front-to-rear direction of the part connection structure of the auxiliary arm 10. The positive side of the X-axis is the extension direction, which is the forward direction. The Y-axis direction is the left-right direction for the auxiliary arm 10, which indicates the swing direction. The positive side of the Y-axis is the leftward direction. The Z-axis direction indicates the up-down direction for the auxiliary arm 10, with the positive side of the Z-axis being the upward direction.

[0025] The auxiliary arm 10 has a movable part 20 connected to the weapon 4 via a connection part 5 (first external part), and a base part 40 rotatably connected to a torso part 6 (second external part) of the doll toy 2 by an axis AX1.

[0026] The movable part 20 is slidably connected to the base part 40 . When the doll toy 2 is not holding the weapon 4 and is carrying it on its back, the movable part 20 is fully pushed into the base part 40 and is housed therein, and the auxiliary arm 10 is in its most contracted state (see FIG. 1). In order for the doll toy 2 to hold the weapon 4, the movable part 20 is fully pulled out from the base part 40, and the auxiliary arm 10 is fully extended, making it possible for it to swing relatively to the base part 40 about the axis AX2 (see FIG. 2).

[0027] The connection part 5 is rotatably connected to the movable part 20 by an axis AX3. In the doll toy 2, the auxiliary arm 10 can be changed into various forms depending on 1) the orientation of the base part 40 relative to the body part 6, 2) the extent to which the movable part 20 is pulled out from the base part 40, 3) the extent to which the movable part 20 swings relative to the base part 40 in the maximum extension state, and 4) the extent to which the connection part 5 is turned relative to the movable part 20. Of course, even if we focus on the auxiliary arm 10 itself, it can be freely extended, retracted, and bent. And the auxiliary arm 10 appears to be auxiliary supporting the weapon 4 in various postures corresponding to various poses of the doll toy 2.

[0028] 5 is a perspective external view showing an example of movable part 20. Movable part 20 is a rod-shaped member and includes a protrusion 21 provided on the underside of the end portion on the retraction direction side (rear end side; end portion on the negative side of the X-axis), a plurality of recesses 24 arranged along the extension / contraction direction on each of the left and right side surfaces, and a first connecting portion 26 provided on the end portion on the extension direction side (front end side; end portion on the positive side of the X-axis).

[0029] The protrusion 21 has a cylindrical neck 22 that protrudes downward (in the negative Z-axis direction), and a head 23 at the lower end of the neck 22 that is wider than the neck 22. The head 23 forms a circular flange that protrudes like a brim from the neck 22. The diameter of the head 23 is set to be the same as or slightly smaller than the left-right width of the movable part 20.

[0030] The first connecting portion 26 is a portion to which a connecting part 5 (first external part; see FIG. 2) for connecting the weapon 4 is connected.

[0031] FIG. 6 is a top view showing an example of the base part 40. FIG. 7 is an XZ cross-sectional view showing an example of the base part 40. FIG. 8 is a perspective external view showing an example of the base part 40, seen from diagonally below. The base part 40 is a rod-shaped component that accommodates the movable part 20 so as to be relatively movable in a predetermined forward / backward direction (the extension / retraction direction for the auxiliary arm 10; the X-axis direction), and is symmetrical on the left and right. The base part 40 has a second connecting part 42 which is an insertion hole through which the axis AX1 of the body part 6 (second external part; see FIG. 2) is inserted, a first guide part 50, a second guide part 60, and a third guide part 70.

[0032] The first guide parts 50 are parts that correspond to the left and right side walls of the accommodation space that accommodates the movable part 20, and come into sliding contact with the left and right side surfaces of the movable part 20 to guide the movable part 20 in a predetermined forward and backward direction.

[0033] The first guide part 50 has elastic protrusions 51 on each of the surfaces facing the left and right side surfaces of the movable part 20. The elastic protrusions 51 have a protrusion dimension capable of interfering with the recess 24 of the movable part 20, and have a shape such that their tip portions can be fitted into the recess 24.

[0034] The second guide portion 60 is a portion corresponding to the bottom surface of the storage space that houses the movable part 20, and has a first rail portion 61 on the retracted side (negative side of the X-axis), a second rail portion 62 on the extended side (positive side of the X-axis), and a receiving portion 63 which is a receiving space for inserting the protrusion 21 of the movable part 20 into these rail portions.

[0035] In the second guide portion 60, the first rail portion 61 and the second rail portion 62 are provided with a receiving portion 63 therebetween, that is, with a gap therebetween, the receiving portion 63. In this embodiment, the first rail portion 61 and the second rail portion 62 are arranged in a straight line along the advance / retract direction of the movable part 20 (the extension / retraction direction for the auxiliary arm 10) with the receiving portion 63 therebetween. In other words, in this embodiment, the first rail portion 61 and the second rail portion 62 are provided on a straight line with a gap therebetween, the receiving portion 63, in the advance / retract direction.

[0036] The first rail portion 61 and the second rail portion 62 are formed by providing elongated holes parallel to the extension / contraction direction on the bottom surface of the storage space of the movable part 20. The groove width (length in the Y-axis direction: length in the left-right direction) of the first rail portion 61 and the second rail portion 62 is set to be larger than the diameter of the neck portion 22 of the protrusion 21 (see FIG. 5), smaller than the diameter of the head portion 23, and smaller than the left-right width of the section where the recess 24 of the movable part 20 is arranged.

[0037] The front-rear width of the receiving portion 63 (length in the X-axis direction: length in the front-rear direction) is set to be larger than the diameter of the head 23 of the protrusion 21, i.e., the maximum front-rear width of the protrusion 21. The left-right width of the receiving portion 63 is set to be larger than the diameter of the head 23 of the protrusion 21, i.e., the maximum left-right width of the protrusion 21. The receiving portion 63 can insert the protrusion 21 from above to below until the protrusion 21 reaches a position lower than the first rail portion 61 and the second rail portion 62. The position of the receiving portion 63 is indicated to the user by the markings 57 provided on the left and right side surfaces of the first guide portion 50 (see FIGS. 4, 8, and 9), and alignment when assembling the auxiliary arm 10 is easy. In other words, the markings 57 (indication marks) are provided at positions visible from the outside of the first guide portion 50 and at positions corresponding to the positions where the receiving portion 63 is provided.

[0038] In other words, the groove width of the first rail portion 61 and the second rail portion 62 is such that the neck portion 22 of the protrusion 21 can be inserted but not the head portion 23. When the protrusion 21 is inserted into the receiving portion 63 from above and then the neck portion 22 is inserted into the rail groove of the first rail portion 61 or the second rail portion 62 with the head portion 23 positioned below the rail, the movable part 20 is connected to the base part 40 and becomes slidable and cannot come off in the vertical direction.

[0039] The first rail portion 61 has a pair of elastic protrusions 64 on opposing surfaces of the groove. The elastic protrusions 64 are provided in a position immediately prior to the storage position P1 so as to come into close contact with the surface of the extension side (positive side of the X-axis) of the neck portion 22 of the protrusion 21 when the protrusion 21 is located at a storage position P1 (shown by a dashed circle in FIG. 6) corresponding to the retracted side limit position. The protrusion 21 can move beyond the elastic protrusions 64 to the storage position P1 by elastically deforming the elastic protrusions 64. Conversely, in order to move out of the storage position P1, the protrusion 21 must again move beyond the elastic protrusions 64, and the elastic protrusions 64 function to hold the protrusion 21 at the storage position P1.

[0040] Similarly, the second rail portion 62 also has a pair of elastic protrusions 64 on opposing surfaces of the groove. The elastic protrusions 64 are provided in a position immediately before the extended position P2 so as to come into close contact with the surface of the retracted side (X-axis minus side) of the neck portion 22 of the protrusion 21 when the protrusion 21 is located at the extended position P2 (shown by a dashed circle in FIG. 6), which is the extended side limit position. The protrusion 21 can move beyond the elastic protrusions 64 to the extended position P2 by elastically deforming the elastic protrusions 64. Conversely, in order to move out of the extended position P2, the protrusion 21 must again pass over the elastic protrusions 64, and the elastic protrusions 64 serve to hold the protrusion 21 in the extended position P2.

[0041] Focusing on the respective guiding ranges of the first guide part 50 and the second guide part 60, the guiding range W1 of the first guide part 50 is set wider than the guiding range W2 of the second guide part 60 on the retracted side (negative side of the X-axis), but conversely, on the extended side (positive side of the X-axis), it only reaches just before the extended position P2. In other words, at one end on one side in the extension / contraction direction, there is no guidance by the first guide part 50, but there is guidance by the second guide part 60.

[0042] Therefore, when the movable part 20 is fully pulled out from the base part 40 and the auxiliary arm 10 is fully extended, the protrusion 21 of the movable part 20 reaches the extended position P2, and the movable part 20 is no longer held in position by the first guide part 50, and becomes able to swing relative to the base part 40 around the axis AX2.

[0043] In addition, when the protrusion 21 of the movable part 20 reaches the extended position P2, the elastic protrusion 64 acts to hold the protrusion 21 at the extended position P2. This prevents the movable part 20 from shifting in the retracted direction when the user performs a swing operation, and prevents the movable part 20 from coming into contact with the first guide part 50 again, making it difficult to perform a swing operation. In addition, when the movable part 20 reaches the extended position P2, the elastic protrusion 64 presses the neck part 22 to tighten the protrusion 21, generating appropriate friction (twisting resistance) between the protrusion 21 and the second guide part 60, and the relative position of the movable part 20 and the base part 40 after swinging is maintained. The extended position P2 is a position that can be called a bearing for the protrusion 21.

[0044] Similarly, when the movable part 20 is pushed all the way in from the base part 40 and the auxiliary arm 10 is retracted to the maximum extent, the movable part 20 is already held in its position by the first guide part 50 until the protrusion 21 of the movable part 20 reaches the storage position P1, and is no longer able to swing relative to the base part 40.

[0045] When the protrusion 21 of the movable part 20 reaches the storage position P1, the protrusion 21 is held at the storage position P1 by the action of the elastic protrusion 64. When held at the storage position P1, the neck part 22 is tightened by the elastic protrusion 64, so that an appropriate resistance is generated between the protrusion 21 and the second guide part 60, and the movable part 20 is held in a state where it is stored in the base part 40.

[0046] The third guide portion 70 is a wall portion provided in a downwardly convex shape from the lower surface of the front side of the base part 40, and has a generally horseshoe shape when viewed from below. The retracted side of the third guide portion 70 reaches a position that overlaps with the left and right sides of the receiving portion 63 of the second guide portion 60. The left and right inner width dimensions of the third guide portion 70 are set slightly larger than the diameter of the head 23 of the protrusion 21.

[0047] 9 is a perspective view for explaining the assembly and extension / contraction operation of the auxiliary arm 10. For ease of understanding, the base part 40 is shown cut along the XZ cross section.

[0048] The user uses the mark portion 57 as a reference for alignment, specifically, positions the protrusion 21 directly above the mark portion 57 on the positive side of the Z axis, and then inserts the protrusion 21 of the movable part 20 from above into the receiving portion 63 of the second guide portion 60. The user can know the limit of the insertion when the lower surface of the portion having the recess 24 of the movable part 20 hits the upper surface of the second rail portion 62 of the second guide portion 60.

[0049] At this time, the protrusion 21 inserted into the receiving portion 63 is not engaged with either the first rail portion 61 or the second rail portion 62, but the outer surface of the head portion 23 is guided in the extension / contraction direction (X-axis direction) with its left / right movement (movement in the Y-axis direction) restricted by the inner surface of the third guide portion 70. Therefore, when the user slides the movable part 20 in the extension direction (X-axis positive direction) or contraction direction (X-axis negative direction) of the protrusion 21 while being guided in this manner, the protrusion 21 engages with either the first rail portion 61 or the second rail portion 62, completing the connection. The movable part 20 is in a state in which the head portion 23 of the protrusion 21 protrudes from the storage space of the base part 40.

[0050] When the connection is complete, the elastic protrusions 51 protruding from the inner surface of the first guide part 50 become the same height as the recesses 24 of the movable part 20. When the movable part 20 is slid in the extension / contraction direction, the elastic protrusions 51 overcome the thresholds of the adjacent recesses 24 while elastically deforming, thereby generating an appropriate sense of operational resistance in the sliding operation of the movable part 20 and improving the quality of the operational feel. In addition, the resistance generated when the elastic protrusions 51 overcome the threshold while elastically deforming creates an effect of maintaining the current position of the movable part 20 relative to the base part 40.

[0051] When the movable part 20 is extended or retracted, the protrusion 21 passes through the receiving portion 63. The receiving portion 63 does not have a structure equivalent to a rail portion that sandwiches and guides the neck portion 22 of the protrusion 21, like the first rail portion 61 and the second rail portion 62, so at first glance it may seem that the protrusion 21 cannot move smoothly between the first rail portion 61 and the second rail portion 62. However, while passing through the receiving portion 63, the head portion 23 of the protrusion 21 is guided by the third guide portion 70, so it slides smoothly between the first rail portion 61 and the second rail portion 62.

[0052] As described above, according to the present embodiment, a part connection structure that is stretchable and bendable can be realized with fewer parts than conventional parts. A part connection structure that is stretchable and bendable can be realized with only two pieces. Compared to conventional three-piece connection structures, the structure is simpler and easier to assemble, and manufacturing costs can be reduced.

[0053] [Modifications] The embodiments to which the present invention can be applied are not limited to the above examples, and components can be added, omitted, or modified as appropriate.

[0054] (Variation 1) For example, although an example designed as a humanoid robot weapon has been shown as an example of the doll toy 2, the design of the doll toy 2 to which the present invention is applicable is not limited to this. For example, it may be a beast-type or insect-type robot weapon, a multi-legged tank, etc. Also, if the exterior is equivalent to skin, the doll toy 2 may be a figure of a character appearing in a manga or anime.

[0055] (Variation 2) In the above embodiment, the head 23 is extended from the lower end of the neck 22 all around to form a disk shape, a so-called flange shape, but the shape of the head 23 is not limited to this. For example, the head 23 may be partially extended and widened only in the left-right direction. Alternatively, the head 23 may be spherical. If the head 23 is spherical, in the extended position P2, the movable part 20 is equivalent to being connected to the base part 40 by a ball joint, so that a structure that allows it to swing not only left-right but also up-down can be realized.
