Japanese Patent Application No. 2004-331039

The present invention provides a component member used for a three-dimensional structure such as a doll, a toy robot, a toy animal, and more particularly, a component member having a movable part such as a joint part capable of arbitrary movement such as bending and expansion / contraction. To do. Moreover, the structural member provided with the movable part which can return easily from the expansion | extension state to the contracted state of a basic form is provided. Furthermore, the present invention provides a structural member that includes a plurality of movable parts and has a predetermined length as a whole, and that can be naturally moved, such as bent and stretched, with respect to each movable part.

Means for solving the above-mentioned problems are as follows. That is, the constituent members such as a doll and a toy robot according to the present invention include a movable part such as a joint part having a bellows structure that can be bent and stretched, a locking part disposed at both ends of the movable part, and a movable part. And an elastic member that is urged and locked to the locking portion, and when the movable portion of the bellows structure is in an extended state, the movable portion is contracted from both ends by the biasing force of the elastic member. Towed.

Further, the movable portion having a bellows structure that can be bent and stretched, the connecting portion that is detachably attached to the movable portion, and the engaging portion that is disposed in the connecting portion and disposed in the connecting portion is urged and locked. When the movable part of the bellows structure that is connected via the connecting part is in the extended state, the movable part is pulled in the contracting direction from both ends by the urging force of the elastic member.

Also, the movable part having a bellows structure that can be bent and stretched, the connecting part that is detachably attached to the movable part, and the engaging part that is disposed in the movable part and disposed on the connecting part is detachably engaged. When the movable part is connected via the connecting part, the elastic member is pulled to adjust the urging force and elastic to the locking part of the connecting part separated from the movable part. The member is detachably locked.

Then, the elastic member is locked to the substantially central portion of the locking portion disposed at both ends of the movable portion, and when the movable portion having a bellows structure that can be bent and stretched is in an extended state, the elastic member is disposed in the movable portion. The elastic member is positioned substantially at the center of the movable part. Further, when the elastic member is inserted into the center hole of the center positioning portion disposed at both ends of the movable portion and the movable portion of the bellows structure that can be bent and stretched is in an extended state, the elastic member disposed in the movable portion is The movable part is positioned substantially in the center.

Since the movable part such as the joint part of the constituent member has a bellows structure, any movement including bending and expansion / contraction is possible. Further, the movable part can be easily returned from the extended state to the stable basic form (contracted state) by the biasing force of the elastic member, and deformation of the bellows structure is prevented. A component member having a predetermined length is secured by connecting the plurality of movable parts. Further, by adjusting the urging force of the elastic member of each movable part, natural movement of each movable part such as bending and expansion / contraction becomes possible.

An embodiment of a component member 1 including a doll, a toy robot, a toy animal, etc., particularly a movable member 2 such as a joint, will be described with reference to the drawings. 1 to 4, the movable part 2 of the constituent member 1 has a hollow bellows structure 3. The accordion structure 3 allows the movable part 2 to be arbitrarily moved, such as bent and stretched. The single component 1 provided with one movable part 2 can be used for, for example, some joint parts such as a neck part and an elbow part of an arm (see FIG. 12, but the neck part is not shown). The movable portion 2 has cylindrical portions 4 and 4 at both ends, and end members 6 are detachably attached to the cylindrical portions 4 and 4. The end member 6 which has the latching | locking part 5 is cylindrical, and the latching | locking part 5 is a latching pin arrange | positioned in the direction orthogonal to an axial center. The locking part 5 may be anything that locks the elastic member, and is not limited to a locking pin. The elastic member 9 arranged in the movable portion 2 is a linear rubber string or spring that can be biased, and is latched to the locking pin 5 in a biased state by latching or binding the end of the elastic member 9. Is done. In the case of illustration, the elastic member 9 is a ring-shaped rubber string, and is latched by the latch pin 5 detachably inserted into the pair of small holes 7, 7 of the end member 6. When the movable part 2 having the bellows structure 3 is in a linear stretched state, the movable part 2 is pulled in the contracting direction from both ends by the biasing force of the biased elastic member 9, and the basic form is contracted (see FIG. Return to steps 1, 2, and 3).

In this case, the movable part 2 naturally returns to the contracted state when set to a large force, but the force is set slightly smaller, while a slight force is applied to the stretched movable part 2 (for example, the movable part 2 with a fingertip). Or the like), the movable part 2 may return to the contracted state. In any case, the movable portion 2 can maintain its basic form by returning to the contracted state, and unnecessary deformation of the bellows structure is prevented (the same applies when a plurality of movable portions described later are connected).

The structural member 1 can also have a structure in which the movable part 2 is connected. 5 to 8, the movable part 2 is connected via the connecting part 10. That is, the outer diameter of the cylindrical connecting portion 10 is slightly smaller than the inner diameter of the end portion (tubular portion) 4 of the movable portion (see FIGS. 5 and 6), or the inner diameter of the cylindrical connecting portion is set to the end portion of the movable portion. It is formed slightly larger than the outer diameter of the (tube portion) (not shown), and the end portions 4 of the pair of movable portions 2 are detachably attached to both ends of the connecting portion 10. For example, the end portion 4 of one movable portion and the end portion 4 of the other movable portion are respectively attached to both end portions of the connecting portion 10b in FIG. Thereby, the movable parts 2 and 2 are connected via the connecting part 10, and the component member 1 having a predetermined length including the plurality of movable parts 2 is formed.

The connecting portion 10 has a locking portion 5, and the elastic member 9 disposed in the movable portion 2 of the bellows structure 3 is locked to the locking portion 5. The elastic member 9 can be urged, such as a linear rubber string, a spring, the elastic member 9 is locked to the locking portions 5 provided at both ends of the movable portion 2, The locking portion is a locking pin 5 arranged in a direction orthogonal to the axis, and the elastic member 9 is locked to the locking pin 5 by connecting the end portions or by latching, etc. Is the same as that of the single movable part 2. When the movable portion 2 having the bellows structure is in a linear stretched state, each movable portion 5 is pulled in the contracting direction from both ends by the biased elastic member 9, and returns to the basic form (contracted state) (FIG. 5 and 6). 8 shows that in the connected component 1, the movable portion 2a has a bellows structure in a contracted state, the movable portion 2b has a bellows structure in an expanded state, and the movable portion 2c has a bellows structure in a bent state.

Even in the joint part, it is necessary to provide a difference in strength between the urging forces of each part such as the shoulder part, the elbow part, and the wrist depending on the structure and type of the doll. That is, a large load is applied to the joint portion of the shoulder portion while a stable movement is required. Therefore, it is necessary to relatively increase the urging force. Also, since the joint part of the elbow part is required to move more flexibly than the shoulder part, the biasing force should be smaller than that of the elbow part. Furthermore, since the wrist joint portion is required to have a flexible and delicate movement corresponding to the movement of the hand, it is necessary to minimize the urging force.

In such a case, when the doll or the like is assembled, that is, when the plurality of movable parts 2 are connected via the connecting part 10, the urging force of the elastic member 9 in the movable part 2 can be appropriately adjusted. That is, the component member 1 includes a movable part 2 having a bellows structure 3 that can be bent and stretched, a connecting part 10 that is detachably attached to the movable part 2, and disposed in the movable part 2 and disposed in the connecting part 10. And an elastic member 9 urged by being detachably locked to the locking portion 5. And when connecting the movable part 2 via the connection part 10, while adjusting the urging | biasing force by pulling the elastic member 9, it is the state which is not mounted | worn with the connection part 10b separated from the movable part 5, ie, the movable part 2. The elastic member 9 (end part) is detachably locked to the locking part 5 of the connecting part 10b.

The adjustment of the urging force and the means and method for locking the elastic member 9 are arbitrary, but a specific example thereof is as follows. When the elastic member is the rubber cord 9 and the locking portion is the locking pin 5, first, the connecting portion 10a. The rubber string 9 is locked to the locking pin 5 (see FIG. 7). As a locking method, the rubber cord 9 is wound around the locking pin 5 of the separated connecting portion 10a before being attached to the movable portion 2. Then, the rubber string 9 is inserted into the hollow movable portion 2, and the connecting portion 10b is attached to one end portion 4 of the adjacent movable portion 2 (the movable portion 2 on the right side of the connecting portion 10b in FIG. 7). The connecting part 10b and the movable part 2 are detachable. Further, the rubber string 9 protruding from the other end 4 of the movable part 2 is arranged so as to be wound around the locking pin 5 of the separated connecting part 10b before being attached to the movable part 2, and the pair of locking pins 5, 5 The rubber string 9 stretched between them is pulled from the tip side, and the urging force of the elastic member 9 is adjusted appropriately. The adjusted rubber string 9 is tied to the front end side 11 to form a ring shape. When the connecting portion 10 b is attached to the end portion 4 of the movable portion, the elastic member 9 that is locked to the pair of locking portions 5 and 5 and whose biasing force is adjusted is disposed in the movable portion 2. The connecting part 10b and the movable part 2 are detachable. Similarly, when connecting the other movable part 2, the elastic member whose biasing force has been adjusted is connected to a pair of locking parts (in FIG. 7, the locking part 5 of the connecting part 10b and the locking part of the right end member 6). 5), the movable part may be detachably attached to the connecting part and the end member.

Since the movable part 2 is detachably attached to the connecting part 10 and the end member 6, the movable part 2 and the connecting part 10 can be separated after being connected once. Therefore, the adjustment of the biasing force of the elastic member can be performed not only when the movable part 2 is connected, but also after the connection, by separating the movable part 2 from the connecting part 10. Is possible (or easy). The movable part 2 and the movable part 2 and / or the movable part 2 and the coupling part 10 can be bonded together with an adhesive or the like in a connected state, or can be simply fixed by an adhesive tape. The connecting portion 10 attached to the movable portion 2 gives strength and rigidity to the end portion 4.

A linear elastic member 9 such as a rubber string disposed in the movable portion 2 is disposed at a substantially central portion (axial center) of the movable portion 2. That is, first, the elastic member 9 is locked to substantially the center of the locking portions 5 (locking pins) on both sides of the movable portion 2 (see FIGS. 2 and 6). A center positioning portion 13 having a center hole 14 is disposed on both sides of the movable portion 2, and the elastic member 9 inserted through the center hole 14 is held in the center portion. The center positioning part 13 is preferably provided close to the bellows structure part 3 of the movable part 2. The center positioning portion 13 is not limited to an annular shape. When the movable portion 2 having the bellows structure is linear, the elastic member 9 is positioned at the center of the center of the movable portion 2, and therefore the movable portion 2 in the expanded state can be easily returned to the contracted state (basic form) by the biasing force. To do. Further, even when the movable portion 2 is in a bent state, the contact between the elastic member 9 and the movable portion 2 (inner peripheral surface) is limited, and excessive deformation of the bellows structure 3 is prevented.

9 to 11 show the locking part 5 having another structure. That is, the holding part 16 fitted to the annular part 15 has a notch part 17 in the radial direction, and the holding part 16 in the annular part 15 is pressed against the linear elastic member 9 arranged in the notch part 17. Hold. The elastic member 9 of the notch 17 is preferably disposed at the center of the holding part 16 (see FIG. 11). The annular portion 15 is detachably attached to the end portion 4 of the movable portion, and the elastic member 9 is maintained substantially at the center of the locking portion 5.

Furthermore, the center positioning part 13 is extended from the holding part 16 to a substantially central position of the movable part 2 (the bellows structure part 3). The center positioning portion 13 is a rod having a circular section with a slightly narrowed tip 12, and the tip 12 of one center positioning portion and the tip 12 of the other center positioning are arranged in the movable portion 2 so as to face each other. . The center positioning portion 13 has appropriate flexibility such as soft synthetic resin, and holds the elastic member 9 at the center of the notch 17 in the radial direction, as in the case of the holding portion 16. When the movable part 2 is bent, the center positioning part 13 prevents the bellows structure 3 from being bent excessively. For example, sudden bending of the bellows structure 3 from a portion adjacent to the end 4 is prevented, and a natural and stable bending state is expressed. Further, the restoring force of the center positioning part 13 extending to the movable part 2 facilitates the restoration of the movable part 2 to the linear state. Note that the plurality of movable portions can be detachably mounted by connecting the cylindrical portions of the end portions having the engaging portions without being connected to each other, and can be connected to each other (not shown).

The component 1 is attached to the base 19 of the trunk. Although the attachment means is arbitrary, for example, the end of the component member 1 is fitted into the recess 20 formed in the base 19 of the trunk, or is fixed to the recess 20 with an adhesive. You may attach via fixtures, such as a metal fitting (not shown). Moreover, the exterior part which has an appropriate softness | flexibility can also be provided in the outer side of the movable part 2 (not shown).
