  These shaped objects are based on keeping the shape constant, and like general buildings such as reinforced concrete structures and wooden structures, the overall appearance changes greatly depending on the surrounding environment changes. There has been no design that has been actively aimed at. For this reason, the degree of freedom in structural design is low, and as a result, the form of the completed model is fixed and uniform.

  The present invention has been made in consideration of the above-described matters, and an object of the present invention is to provide a shaped article that can change the form in accordance with the surrounding environment change and increase the degree of freedom in structural design.

  In order to achieve the above object, a modeled object according to the present invention is a modeled object configured by connecting a plurality of extendable tubes, and the model itself is stretchable or filled in the tube. The degree of expansion and contraction accompanying the change in the surrounding environment of at least some of the tubes is different from that of the other tubes by changing the ease of expansion or contraction of the filling material. ).

  In addition, the modeled object according to the present invention is a modeled object configured by connecting a plurality of extendable tubes, and the tubes are divided into a plurality of groups, and the tubes according to changes in the surrounding environment of each tube The degree of expansion or contraction of the filling material in the tube varies from group to group, and the tube is filled at least in groups so that the filling material filled in the tube of one group does not move to another group. May be configured to be sealable (claim 2).

  In the shaped article, the tube has at least two end portions, each end portion is provided with a joining tube, and the plurality of tubes are connected so as to form a framework by coupling via the joining tube. (Claim 3).

  In the present invention, it is possible to obtain a shaped object that changes its form according to the surrounding environment change and can increase the degree of freedom in structural design.

  That is, in the shaped object of the invention according to each claim of the present application, when the ambient temperature (air temperature), the amount of solar radiation, and the like change, the temperature of the tube itself and the filling material in the tube change, and along with this change The shape of the tube changes or the volume of the filling material changes. Since the ease of change is not uniform, as a result, the shape of the model is greatly changed.

  That is, the conventional shaped object is based on the fact that the shape is constant, and the position coordinates (XYZ coordinates) are exclusively used as design parameters, and the time axis (t) like the environmental change is not used as a parameter. On the other hand, the modeled object of the present invention is designed by introducing the time axis (t) as a parameter, and the degree of freedom in structural design increases, and the space for constructing the modeled object changes every moment. It can be like a life form that responds to the surrounding environment.

  In the modeled object of the invention according to claim 3, it is possible to improve the efficiency of connecting the tubes by unitizing the tubes.

(A) is a perspective view which shows roughly the structure of the molded article which concerns on one embodiment of this invention, (B) is the image figure which looked at the said molded article from the inner side. (A) is a perspective view which shows schematically the tube which comprises the framework of the said molded article, (B) is explanatory drawing which shows the state with which the several tube was connected. (A) And (B) is the front view and top view which show the structure of the conventional molded article roughly.

  Embodiments of the present invention will be described below with reference to the drawings.

  A model 1 shown in FIGS. 1 (A) and 1 (B) is a building that is formed in a tunnel shape and has a network structure throughout, and as shown in FIGS. 2 (A) and 2 (B), a tube that can be expanded and contracted. The framework is configured by connecting a plurality of two.

  And the modeling thing 1 is easy to carry out the expansion | swelling and / or contraction of the filling material with which it fills in the tube 2 so that it may deform | transform large according to the change of the surrounding environment (for example, temperature (temperature), solar radiation amount, etc.). The degree of expansion and contraction accompanying the change in the surrounding environment of at least some of the tubes 2 is made different from that of the other tubes 2.

  First, the tubes 2 will be described. Each tube 2 is bifurcated and has three ends as shown in FIGS. 2 (A) and 2 (B), and a joining pipe (joint) 3 is provided at each end. The plurality of tubes 2 are connected so as to form a framework by coupling via the joint tube 3.

  Here, FIG. 2A shows an example in which the joining pipes 3 can be directly connected to each other (in other words, an example in which the tubes 2 are connected to each other). Instead, two or more joining pipes 3 may be connected via a separate joint member. In any case, a structure such as a well-known pipe joint or coupling fitting can be adopted as a structure for performing the connection. For example, a screw-in type (for example, a joining pipe 3 formed with a male screw and a female screw is formed. The joint pipe 3 and the union type (for example, a union screw is formed on one joint pipe 3 and a union collar is formed on the other joint pipe 3, and a union nut is fitted over both the joint pipes 3 to connect them. Threaded union and the type found in plug-in welded union), flange type (for example, both joint pipes 3 are provided with pipe flanges, and both pipe flanges in contact with each other are fastened with bolts and nuts, or with quick fasteners. It is sufficient to adopt various joining methods such as a welding method. In addition, illustration of the joining pipe | tube 3 is abbreviate | omitted in FIG. 1 (A) and (B).

  The material of the tube 2 is a material that has elasticity and does not allow liquid or gas to be filled in the tube 2 to pass therethrough. Examples of such a material include elasticity such as rubber and soft plastic. Materials can be mentioned. In addition, it is also conceivable that the tube 2 is made of a membrane material such as a nonwoven fabric, a woven fabric, or a film whose inner surface is sealed with liquid or gas.

  On the other hand, examples of the filling material filled in the tube 2 include a material that becomes a liquid (for example, water) at room temperature and a material that becomes a gas (for example, air, argon gas, nitrogen gas, helium gas). In addition, introduction | transduction of the filling material in the tube 2 and its derivation | leading-out may be performed from the joining pipe 3, and the tube 2 itself may be provided with the opening | closing opening which can be opened and closed, and may be performed using the introduction port.

  In order to vary the ease of expansion and / or contraction of the filling material filled in the tube 2, for example, the type (thermal expansion coefficient) and concentration of the liquid and / or gas filled in the tube 2 are changed. What is necessary is just to make it different or to make distribution (ratio) of the liquid and gas with which the tube 2 is filled differ.

  In the modeled object 1 of this example, the tubes 2 are divided into a plurality of groups, and the degree of expansion and / or contraction of the filling material in the tubes 2 due to changes in the surrounding environment of each tube 2 is different for each group. The filling material filled in the tube 2 is different for each group, and the tube 2 can seal the filling material at least in groups so that the filling material filled in the tube 2 of one group does not move to another group. It is configured.

  In FIG. 2B, the tube 2 is divided into a tube 2A group constituting the first group, a tube 2B group constituting the second group, and a tube 2C group constituting the third group. Show. The number of groups may be two or four or more. Moreover, the tube 2 which comprises a group may be single or plural, and the number of the tubes 2 which comprise a group may be the same or different between groups.

  Here, as a means for sealing the filling material of the tube 2 for each group and sealing the filling material in units of groups, for example, a valve mechanism (open / close valve or check valve) or a plug member is provided in the joint tube 3 and filling is performed. If the material is properly controlled or prevented from passing through the joining pipe 3, or the joining pipes 3 are connected via a separate joint member (adapter) having a function as a valve mechanism or a plug member. Good. Moreover, what is necessary is just to mount | wear with the plug member, for example, and to seal to the junction pipe 3 which is not connected with the other junction pipe 3. FIG.

  In the modeled object 1 configured as described above, when the temperature around the modeled object 1 (air temperature), the amount of solar radiation, or the like changes, the temperature of the filling material in the tube 2 changes. The internal pressure (filling material volume) changes. The ease of change of the internal pressure of the tube 2 varies from group to group, and the expansion / contraction degree (expansion and / or contraction degree) of the tube 2 according to the environmental change is not uniform. The shape of 1 will change greatly.

  That is, the conventional shaped object is based on the fact that the shape is constant, and the position coordinates (XYZ coordinates) are exclusively used as design parameters, and the time axis (t) like the environmental change is not used as a parameter. On the other hand, the modeled object 1 of this example is designed by introducing the time axis (t) as a parameter, and the degree of freedom in structural design is increased. It can be like a life form that responds to the changing surrounding environment.

  In addition, this invention is not limited to said embodiment at all, Of course, it can change and implement variously in the range which does not deviate from the summary of this invention.

  For example, FIGS. 2A and 2B show an example in which each tube 2 is bifurcated and has three ends (an example in which each tube has the same shape). Not limited, the tube 2 may be unified with other shapes, or the shape may not be unified. When the shape of the tube 2 is not unified, the tube 2 only needs to have at least two ends, and in particular, the shaped article 1 includes one or more tubes 2 having at least three ends, The larger the number, the easier it is to make the shape of the shaped article 1 various, which is preferable.

  FIG. 2A shows an example in which one tube 2 is filled with only one kind of filling material. However, the present invention is not limited to this. For example, one tube 2 is partitioned into a plurality of chambers. Each chamber may be filled with a different filling material.

  2A and 2B show an example in which the ease of expansion and / or contraction of the filling material filled in the tube 2 is different. However, the present invention is not limited to this, and the tube 2 itself The degree of expansion and / or contraction of the tube 2 may be made different so that the degree of expansion and contraction accompanying the change in the surrounding environment of at least some of the tubes 2 may be different from those of the other tubes 2.

  As means for making the tube 2 itself easy to expand and / or contract, specifically, the tube 2 has a different diameter, thickness, length, volume, and shape. Examples include biasing in the circumferential direction, using an anisotropic material for the tube 2, and having different variations in the material density of the tube 2. In addition, a material that absorbs moisture and expands when the humidity around the tube 2 increases may be provided on the outer wall portion of some tubes 2. Furthermore, the temperature change of the filling material in the tube 2 may be made different by changing the reflectance and absorption rate of light on the outer surface of the tube 2. In addition, some of the tubes 2 may be arranged in a state where they are intentionally twisted, stretched, bent or entangled.

  Here, when the diameters of the tubes 2 are not unified, it is necessary to connect the tubes 2 having different diameters. In order to connect the tubes 2 having different diameters, for example, the pipes having different diameters are connected by using different diameter pipe joints (for example, different diameter sockets), or pipe flanges having different diameters are provided. What is necessary is just to comprise each joining pipe | tube 3 so that the difference in the diameter of the tube 2 can be absorbed with the joining pipe | tube 3 by pinching | interposing with a diameter quick fastener.

  When it is necessary to increase the in-plane rigidity of the structure formed by the tube 2, the tube 2 may be restrained by a face material such as a film that follows the deformation of the tube 2. In this case, the tube 2 is not restrained by the membrane and is not deformed at all. The restoring force when the tube 2 is deformed is increased by the membrane, and as a result, the in-plane rigidity is increased. Of course, part or all of the membrane may be constituted by a plate-like member that does not follow the deformation of the tube 2. The face material may be bonded to the tube 2 by, for example, bonding or sewing, may be connected to the tube 2 with a rope or the like, or may be integrally formed with the tube 2.

  Moreover, although all the tubes 2 may have elasticity, you may comprise so that only some tubes 2 may have elasticity.

  Although FIG. 1A shows a modeled object 1 formed in a tunnel shape, the present invention is not limited to this, and the modeled object 1 can take various shapes. Or you may have the floor surface comprised with the said face material.

  Needless to say, the modifications described in this specification may be combined as appropriate.
