Abstract

(57) [Abstract] [PROBLEMS] To obtain a human body model in which a soft surface layer is supported by a hard inner layer, has a feel similar to a human body, and is easy to manufacture. SOLUTION: A human body model A is constructed by supporting a surface layer 1 made of a first urethane resin which is soft at the time of curing and an inner layer 2 made of a second urethane resin which is hard at the time of curing.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a mannequin doll, a human body model used for massage and beauty / barber training.

[0002]

[Prior art]

 Conventionally, training manikin models such as mannequin dolls and massages are entirely composed of the same hard or soft material. It is also known to use FRP resin as a core material and coat it with a soft resin.

[0003]

[Problems to be solved by the device]

 By the way, since it is preferable that the surface of the mannequin doll has a feel and texture similar to human skin, it is desirable that the surface is soft rather than hard. In addition, it is desirable that the anatomical model used for massage and lifesaving training has the same elasticity as the human body. The same applies to the head model used for beauty and barber training. In the past, there was a mannequin that was soft in its entirety, but when a soft material was used, the whole became a balloon shape, which lacked stability as a mannequin doll and lacked rigidity for training such as massage. there were. Further, the core material made of FRP resin has to rely on manual work for molding the core material, and the production cannot be automated, resulting in an expensive product.

The present invention solves the above-mentioned problems by providing a human model having a soft surface and elasticity, a soft surface layer supported by a hard inner layer, and which can be automatically produced by a machine. Is what you are trying to do.

[0005]

[Means for Solving the Problems]

 This invention constitutes a human body model by supporting a surface layer made of soft urethane with an inner layer made of hard urethane. The surface layer is obtained by introducing a first urethane resin, which is soft at the time of curing, into a mold, and causing the mold to revolve around the mold to cure the first urethane resin. Is obtained by pouring the second urethane resin, which is hard at the time of curing, into the mold when the first urethane resin gels, and allowing the mold to revolve and cure. Then, the manufacturing is easy.

The amounts of both urethane resins are appropriately selected according to the desired elasticity and the rigidity of the aggregate. In addition, the specific components of the urethane resin are also selected in consideration of elasticity and rigidity.

[0007]

[Action]

 In this invention, since the soft and elastic surface layer is supported by the inner layer which is hard and functions as an aggregate, the surface has elasticity similar to that of a human body and is rigid as a whole human body model.

[0008]

[Embodiment of device]

 FIG. 1 is a sectional view of a human body model A according to an embodiment of the present invention, in which a hard urethane inner layer 2 is closely adhered to the inside of a soft and elastic urethane surface layer 1. Are supported by the inner layer 2 over the entire surface.

An example of the soft urethane component is a mixture of the following liquids A and B in a ratio of 100: 28. Liquid A Polyether polyol 97 parts Colorant 1 part Hygroscopic agent 3 parts Catalyst 1.5 parts Liquid B MDI (methylene diphenyl diisocyanate) 25 parts Plasticizer 75 parts

An example of the hard urethane component is a mixture of the following liquids A and B in a ratio of 100: 70. Liquid A Polyether polyol 97 parts Hygroscopic agent 3 parts Catalyst 0.5 part Liquid B MDI (methylene diphenyl diisocyanate) 100 parts

Next, a method of manufacturing the human body model A will be described. The first urethane resin 11 which is soft at the time of curing is put into the split mold 10 and allowed to rotate and revolve by a rotation molding device (10 minutes at room temperature. 5 revolutions per minute and 8 revolutions per minute). Then, the first urethane resin 11 is formed into a surface shape according to the mold and gelled to obtain the surface layer 1. Next, the charging port 10a of the mold 10 is opened, and the second urethane resin 12, which is hard during curing, is charged into the inside of the first urethane resin 11 and allowed to rotate on its own axis by a rotation molding device (20 at room temperature). The rotation conditions are the same as described above), and the second urethane resin 12 is brought into close contact with the surface layer 1 to be molded and cured to obtain the inner layer 2. After that, the mold 10 is opened and the molded product (human body model) A is taken out.

The surface layer 1 of the human body model A is soft and elastic. This surface layer is supported by the hard inner layer 2. Therefore, when the surface layer is pressed with a finger or the like, the pressure is received by the inner layer 2 which functions as an aggregate, and therefore, when the human body is pressed, the same feel as if the pressure is received by the bone is obtained. . Therefore, when it is used as a human body model for training in massage, lifesaving motion, beauty and barber, it is possible to obtain a motion and feel similar to the human body, and practical training is possible. Further, since the surface layer 1 is soft, an impression close to that of human skin can be obtained, and a mannequin humanoid can be obtained.

[0013]

[Effect of device]

 In the mannequin of this invention, an elastic surface layer made of soft urethane is supported by a hard inner layer made of hard urethane. Therefore, when used as a mannequin doll, the surface gives a soft feel that is close to the skin, and the mannequin doll has a real feeling. In addition, when used as a training model such as a massage, a feeling similar to that when operating on a human body is obtained, and practical training is possible. Since the material is urethane resin, it can be molded at room temperature, and unlike PVC sol, there is no risk of migration of two types of urethane resin during molding, and the surface layer and inner layer are clearly separated. A human body model having a structure close to that of the human body can be obtained. Furthermore, by using urethane as the material, it is possible to perform automatic molding using a mold, which improves productivity.
