Description

Patent Law Article 30 Paragraph 2 Applicable January 8, 2018 Published at Doll Show 52 Winter Asakusa held at Tokyo Metropolitan Industry and Trade Center Taitokan (2-6-5 Hanakawado, Taito-ku, Tokyo)

The present invention relates to a doll whose body is provided with rod-shaped members such as legs and arms, and more particularly to a doll characterized by a joint region arranged in the middle of the rod-shaped members provided on the body.

In the present specification, the concept of "doll" is not limited to all dolls having a body, legs, arms, and head, but also includes so-called doll prime fields without a head. .. In addition, at least all dolls whose required parts such as legs and arms are movable are targeted. For example, the doll is not limited to a doll representing a human male or female, but may be a doll such as an animal, a fantasy creature, a robot, or a monster.

The "body" is generally regarded as a part excluding the arms, legs, and head of the doll, but the body may be a concept including the head.
The "rod-shaped member" has an arm or leg attached to the body as an embodiment in the present specification, but may be a head, a tail of an animal or a monster, an antenna of an insect, or the like. It may be an antenna of a robot or the like, and the concept includes all the members attached to the body in a rod shape.
The "upper arm" is from the base of the arm (the part connected to the shoulder position) to the upper elbow, the "lower arm" is from the lower elbow to the wrist, and the "hand" is. It shall mean from around the wrist to the tip (fingertip).

In the doll industry these days, for example, dolls called figures that have a composition that faithfully replicates the human body (naked body) form have gained popularity especially among adult consumers such as adult men and women. There is.

Consumers such as adult men and women faithfully demand the appearance and movement of humans such as joints, and the needs of these consumers are extremely high.
In Patent Document 1, a joint portion (connecting member) is arranged between the upper arm and the lower arm (forearm), and the upper arm and the joint portion and the lower arm and the joint portion are connected by different axes (biaxial). , It is configured so that double movement can be obtained between the upper arm and the joint, and between the lower arm and the joint, and the range of movement in the elbow region is increased. That is, it provides a joint structure called a so-called double joint, and is trying to reproduce a realistic movement closer to human movement. In particular, Patent Document 1 aims to be able to express a configuration in which the elbow is pointed outward like a human when the elbow is bent.

The needs of figure consumers are endless, and they are demanding more realistic appearances and movements.
For example, in the case of the elbow joint (double joint) disclosed in Patent Document 1, the joint portion constituting the elbow has a thin portion that fits into the opening groove formed at the tip of the lower arm (forearm). It is composed of a thick part formed on the outside, and the appearance shape of this thick part expresses the elbow part.
However, Patent Document 1 expresses a configuration in which the thin-walled portion protrudes outward when the elbow portion is bent, so that the elbow is sharpened outward. However, when the elbow is bent, the thin-walled portion is thinned. A remarkable gap (large gap) is created between the lower end of the portion and the opening groove of the lower arm (forearm). That is, in Patent Document 1, no consideration was given to the treatment of the gap formed between the joint portion constituting the elbow and the lower arm (forearm).
If the gap is noticeably visually recognized in the elbow region in this way, there is a risk that not only will the consumer's interest in seeking more reality be reduced, but also the consumer's willingness to purchase dolls will be impaired.

FIG. 5 and FIG. 7).

The joint portion main body 41 is formed with recesses 43 and 43 slidably fitted to the base portion 65 of the connecting portion 61 on the inner surface on the upper end side of each of the left and right divided portions, and one of the recesses 43. A rod-shaped protruding fitting portion 43b to be inserted into the fitting hole portion 43a of the other recess 43 is provided at the center of the above (FIG. 7).
Therefore, the joint portion main body 41 can be rotated in the front-rear direction by the fitting portion 43b being slidably inserted into the base portion side shaft hole 67 provided in the base portion 65 of the connecting portion 61.

In the recess 43, a slide groove portion 45 that accommodates the guide protrusion 69 of the base 65 so as to be slidable is recessed in an arc shape (FIGS. 5 and 7). The guide protrusion 69 and the slide groove portion 45 have a function of limiting the movement of the joint portion 35 when the lower arm 23 is rotated.

In the slide groove portion 45, the position where the guide protrusion 69 of the base portion 65 abuts when the upper arm 5 and the lower arm 23 are in a straight state (the state of FIG. 1) is the first groove end portion 45a, and the first groove end portion 45a. It is recessed in an arc shape upward with 45a as a base point, and a second groove end portion 45b is formed at a position side by side with the base side shaft hole 67 (FIG. 7). The slide groove portion 45 is formed in the same arc shape as the base portion 65.

In the joint portion main body 41, the outer peripheral surface (outer peripheral surface) 47 connecting the upper end portion 37a and the lower end portion 39a protrudes outward in a gentle arc shape, and the inner peripheral surface (inner peripheral surface) 49 protrudes outward. It is dented in a gentle arc shape toward it.
The left and right side surfaces of the lower region 39 are formed with recesses 51 and 51 for accommodating the tip regions 29b and 29b of the two pieces of axial attachment pieces 29 and 29 located on the upper end side of the lower arm 23 (FIG. 1 to 5 and 7).
In each of the recesses 51 and 51, a first shaft hole 53 and a second shaft hole 55 having a predetermined diameter penetrating over the left and right side surfaces are formed. The lower arm (second member) is fitted with a round bar-shaped first shaft portion 57 coaxially attached to the first shaft hole 53, the lower arm side shaft hole 29a, and the second shaft hole 55. 23 is configured to be rotatable. In the figure, 59 indicates the center position of the shaft attachment portion.

According to the present embodiment, the lower arm 23 is rotated forward, and the recessed region 31a on the front surface 31 side comes into contact with the inner peripheral surface (inner peripheral surface 49) of the joint portion main body 41, and the rotation is restricted. After being (restricted) (after the state shown in FIG. 3), the lower arm 23 is further rotated by rotating the joint body 41 forward.
Then, from the state of FIG. 3, the joint portion main body 41 rotates forward with the fitting portion 43b as an axis, and the lower arm 23 further rotates forward with this (FIG. 4). Then, the rotation operation is controlled (restricted) by the guide projection 69 coming into contact with the second groove end portion 45b of the slide groove portion 45 (FIG. 4). Further, contrary to this operation, when the lower arm 23 is rotated backward to make the arm portion (rod-shaped member) 3 straight, the guide protrusion 69 is the first groove end portion of the slide groove portion 45. It abuts on 45a and further rotation is controlled (restricted).

In the present embodiment, the distance from the center position 59 of the shaft-attached portion to the tip region 29b of the shaft-attached piece 29 is a, and the distance from the center position 59 of the shaft-attached portion to the outer peripheral surface 47 of the joint portion main body 41 is b. When this is done, it is configured to have a relationship of a <b (FIGS. 1 to 5).
With this configuration, the shaft attachment piece 29 on the upper end side of the lower arm 23 can be attached to the outer peripheral surface 47 of the joint portion main body 41 when the lower arm 23 is rotated or when the lower arm 23 is rotated. Since it does not protrude outward, a protruding portion that cannot be seen in a human elbow does not appear, and the reality of the appearance of the elbow can be improved (FIGS. 1 to 4).

In the joint portion main body 41 of the present embodiment, the arc-shaped lower end portion 39a is formed wider than the arc-shaped upper end portion 37a with a large radius of curvature and a gentle curved surface (FIGS. 1 to 5). The curved surface of the lower end portion 39a is such that when the lower arm 23 is rotated in the front-rear direction at the axis center (shaft attachment portion center position) 59 of the first shaft portion 57, the shaft attachment piece 29 of the lower arm 23, It is formed so as to be located on a substantially locus of the deepest portion 33b of the concavely recessed region 33a formed between the 29s (see the rotational state of FIGS. 1 to 4). That is, the distance from the center position 59 of the axial attachment portion of the lower arm 23 to the deepest portion 33b of the concavely recessed region 33a is c, and the lower end portion of the joint portion 35 (joint portion main body 41) from the central position 59 of the axial attachment portion. When the distance to the curved surface of 39a is d, the distance c and the distance d are substantially the same, or the distance c is formed to have a slightly longer relationship (relation of c≈d) than the distance d. ..
In the present embodiment, the rotation is started forward from the state shown in FIG. 1 (the state in which the arm portion 3 is straightened), and the state shown in FIG. 2, that is, the deepest portion 33b of the lower arm 23 is at least. The curved surface of the lower end portion 39a is formed so as to be located on the substantially locus of the deepest portion 33b until it passes through the most protruding region 39b of the lower end portion 39a.

By forming the lower end portion 39a in this way, during the operation of rotating the lower arm 23 forward, the movable region (recessed region) between the lower arm 23 and the axial attachment piece 29, that is, on the rear surface 33 side. Since the outer peripheral surface 39b of the wide lower end portion 39a having a large radius of curvature and a gentle curved surface is not separated from the deepest portion 33b of 33a), the gap G1 generated between the deepest portion 33b of the recessed region 33a is minimized. (Fig. 2). As a result, the interest of consumers who seek more reality will be improved, and consumers will be motivated to purchase dolls.

In the present embodiment described above, the joint structure of the elbow portion of the doll has been described, but the present invention can also be applied to the joint structure of the knee portion of the doll.

The present invention can be used for all dolls regardless of the type of doll, such as humanoid and monster type, as long as the doll has a rod-shaped member having a joint between the first member and the second member on the body. Is.
