Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to, for example, a mannequin joint that can be stably used for a long period of time and can be moved three-dimensionally.

[0002]

[Prior Art]

 The joint of the mannequin is composed of two connecting members that are connected to the mannequin constituent members, and a press-contacting means for press-connecting these connecting members to each other at their facing surfaces. Manikin When moving the constituent members to change their postures, the opposing surfaces that are in pressure contact with each other slide.

[0003]

[Problems to be solved by the device]

 However, the positional relationship between the moved mannequin constituent members is only stable due to the frictional resistance between the pressed and opposed surfaces, and thus lacks stability. Therefore, for example, when the product displayed in the winter is heavy, when the handbag is hung on the arm of the mannequin, or when the customer touches the product being displayed, the attitude of the mannequin displaying the product changes. There were times when it happened. Therefore, one opposing surface is formed into a jagged concavo-convex shape, and the ball that fits into this concave-convex surface is rotatably mounted on the other opposing surface to maintain the positional relationship of the mannequin component members in a certain posture. It is possible to try to have power.

However, in this case, even if the posture-holding force is improved by fitting the uneven surface and the ball, the spherical surface of the ball receives a concentrated load on the other uneven surface, which causes an error in a short time. There is a problem that it becomes a stable state.

Further, since the mannequin has a low posture holding force as described above, the movement of the joint can be only two-dimensional. Therefore, more forms of mannequin are needed.

Therefore, an object of the present invention is to provide a manenki joint that can be used stably for a long period of time, has a high posture holding force, and is capable of three-dimensional movement.

[0007]

[Means for Solving the Problems]

 The means for solving the above-mentioned problems will be described with reference to FIG. 2 of the embodiment. The configuration is such that two members 9 and 9 are held opposite to each other, and these members 9 and 9 are mutually supported. An intermediate portion for connecting the two mannequin component members 3 and 4 that connect the chrysanthemum seat holding structure 7 that is biased in the direction in which the surfaces 9a and 9a are engaged with each other and is rotatable in the circumferential direction in the connection direction. And connecting portions 6 and 6 for connecting the mannequin constituting members 3 and 4 are continuously provided on the radial direction side of the members 9 and 9 in the chrysanthemum holding structure 7. , 5 between at least one of the manikin constituting members 3 (or 4) connected thereto and the mannequin constituting members 3 and 4 which are rotatable in the circumferential direction. Characterized by the mannequin joint 2 forming the chrysanthemum holding structure 7, 7. .

[0008]

[Action]

 That is, according to the above configuration, when the mannequin component is moved to change its posture, the opposing members of the chrysanthemum holding structure are separated from each other against the biasing force, and the mannequin component is desired. Then, the chrysanthemum bearing surfaces of the members facing each other may be meshed with each other by allowing the biasing force to establish the positional relationship. The interlocking surfaces of the chrysanthemum seats are firmly held by the uneven surface and the urging force, and the mannequin component can be oriented in the desired angle and direction.

[0009]

[Effect of the device]

 As a result of the above, according to the present invention, not only the frictional resistance between the flat surfaces as in the prior art but also the posture is maintained in the meshed state by the chrysanthemum seat surface, so the posture holding force is high and stable. Moreover, since the chrysanthemum bearing surfaces are meshed with each other, the load is not concentrated on a part of the bearing surface, and stable use can be achieved for a long period of time. Further, since such a stable and strong posture holding force can be obtained, it is possible to provide a plurality of chrysanthemum holding structures having different rotation directions, such as two or three places, as described above, and the posture can be tertiary. It can be changed originally. Therefore, the scope of application of the integrated mannequin is widened, which contributes to reduction of management costs.

The operation and effect of the elbow joint 2 thus configured will be described below.

First, when the angle formed by the arm member 4 of the mannequin 1 and the second arm member 3 is set, the hemispherical portions 6e, 6e of the connecting members 6, 6 of the elbow joint 2 are separated from each other, or the arm members are 4 by forcibly rotating the chrysanthemum seat holding structure 7 at the intermediate position so as to separate the chrysanthemum seat members 9, 9 from each other against the urging force to bring the meshed state. It is sufficient that the chrysanthemum bearing members 9 and 9 have their chrysanthemum bearing surfaces 9a 1 and 9a meshed with each other by removing them, setting them to desired positions, and letting them be biased. The chrysanthemum seat surfaces 9a, 9a meshed with each other are firmly held in their positional relationship by the uneven surface and the biasing force. In addition, when the direction of the elbow is set, the connecting member 5 and the connecting member 6 on the second arm member 3 side of the elbow joint 2 are separated by pulling downward from the connecting members 6 and 6 or the connecting member of the elbow joint 2. This is performed by using the chrysanthemum holding structure 7 as described above, for example, by forcibly rotating it while holding 5, 5 in a desired direction. Further, when the circumferential direction (twist) of the arm member 4 is set, the arm member 4 is pulled to separate the connecting member 5 and the connecting member 6 on the arm member 4 side of the elbow joint 2 or the elbow joint. Using the chrysanthemum holding structure 7, the connecting members 6 and 6 of the joint 2 are forcibly rotated so as to be in a desired direction, and the like, and this is performed.

Therefore, as described above, since the posture of the arm member is held in the meshed state by the chrysanthemum bearing surfaces 9a, 9a having the unevenness, the posture holding force is high and stable. Moreover, since the chrysanthemum bearing surfaces 9a and 9a are meshed with each other, the load is not concentrated on a part of the bearing surface, and stable use can be achieved for a long period of time. Furthermore, since a stable and strong posture holding force can be obtained in this way, it is possible to provide three chrysanthemum seat holding structures for one joint as described above, and to change the posture three-dimensionally in various ways. .. For this reason, the range of use of the integrated mannequin is widened, and it is not necessary to prepare a large number of mannequins and mannequin constituent members, and management and the like becomes easy.

In the above embodiment, the case where the joints are attached to the shoulder portion, the elbow portion, and the knee portion is shown. However, the joints may be attached to the neck portion, the wrist portion, the waist portion, or the like. .. In that case, the number of chrysanthemum holding structures may be appropriately set to one, two, three, and the rotation direction in accordance with a desired movement.
