Description

  The present invention relates to a three-dimensional structure that can change the shape in one direction to a shape corresponding to the shape of the object by changing the partial protrusion length in one direction according to the shape of the object, and the three-dimensional structure The present invention relates to a three-dimensional modeling apparatus including the three-dimensional model, a molding apparatus including the three-dimensional model, and a molding method using the molding apparatus.

  A three-dimensional modeled object and a three-dimensional modeled apparatus that can change the shape by arbitrarily changing the partial protrusion length in one direction have been proposed (see, for example, Patent Document 1). The three-dimensional structure described in Patent Literature 1 includes a screw assembly including a plurality of screws arranged so as to mesh with each other's screw grooves, and each of the plurality of screws is individually independent. It can rotate and moves independently in one direction and the other direction opposite to the one direction by rotating. In each of the plurality of screws, an engaging portion is provided at an end portion on the other direction side, and a driving portion that rotates the screw is engaged with the engaging portion. When the drive unit is rotationally driven in the state of being engaged with the engagement unit, each of the plurality of screws rotates, and each of the plurality of screws independently moves in one direction and the other direction. Thereby, a solid modeling thing can change a shape. Note that the three-dimensional modeling apparatus includes a three-dimensional model and a driving device having a driving unit that rotates a screw. According to the three-dimensional modeled object or three-dimensional modeled apparatus described in Patent Document 1, when a predetermined screw is rotated and the screw is moved, the adjacent screw does not move carelessly. In addition, by switching the direction in which the screw is rotated, the screw can be moved in one direction and the other direction. Even after the shape of the screw assembly is once formed, the screw assembly can be changed to another shape. It can be easily changed.

  The three-dimensional structure described in Patent Document 1 can be used as an exhibit or the like that displays advertisements, designs, and the like in a three-dimensional manner so as to attract the eyes of a person who performs wind shopping. In addition, the three-dimensional modeled object can be used as a thing that a part of the body comes into contact with and is subjected to a human load, such as a bed, a seating surface or backrest of a chair or sofa, or a pillow. By using a three-dimensional model for the part that the body part contacts, and changing the shape of the one-dimensional side of the three-dimensional model according to the shape of the body, it can be made to correspond to the shape of the part of the body . Furthermore, it is also conceivable to use a three-dimensionally shaped object in which the shape on one side is changed to a shape corresponding to a part of the body as a mold of a molding apparatus for molding a mattress, a pillow or the like of a bed.

Japanese Patent No. 5174278

  Here, when using the solid modeling object and the three-dimensional modeling apparatus described in Patent Document 1 in a form that changes to a shape corresponding to the shape of an object such as a person, the shape of the object is digitized in advance. The amount of screw rotation must be controlled based on the information obtained. For this reason, there is room for improvement in that means for digitizing the shape of the object and means for controlling the amount of rotation of the screw are required.

  In view of the above circumstances, the present invention can change the shape on one side to a shape corresponding to the shape of the object without performing numerical control of the shape of the object or screw rotation control based on the numerical information. It is an object of the present invention to provide a three-dimensional modeled object, a three-dimensional modeled apparatus including the three-dimensional modeled object, a molding apparatus including the three-dimensional modeled object, and a molding method using the molding apparatus.

The three-dimensional object of the present invention that solves the above-mentioned object changes the shape on the one-direction side to a shape corresponding to the shape of the object by changing the partial protrusion length in one direction according to the shape of the object. A three-dimensional model that can
Each of the plurality of screws can be independently rotated, and each of the plurality of screws can rotate independently of the one direction and the one by rotating. A screw assembly that can move independently of the other direction opposite to the direction;
A rotating body that rotates by being applied with power and rotates the screw in an engaged state engaged with the screw;
A contact portion that constitutes an end portion on the one-direction side, and includes a release member that moves along with the movement of the screw and releases the engagement state when the contact portion contacts the object. It is characterized by being.

  Here, the release member includes a sensor that detects that the object has contacted the contact portion, and releases the engagement state when the sensor detects that the object has contacted the contact portion. There may be. The release member may release the engagement state when the object comes into contact with the contact portion. When the contact portion comes into contact with the object, the contact portion stops moving. The engagement state may be released. Further, the rotating body may be manually rotated or rotated by transmission of power from a motor or the like. Furthermore, the object may be a person, a product lined up in a store on a window display, or a model temporarily made of clay or the like. Still further, the three-dimensional object is used in a state in which at least one of the rotating body and the release member is removed after the shape on one side is changed to a shape corresponding to the shape of the object. Also good.

  According to the three-dimensional structure of the present invention, when the screw rotates as the rotating body rotates in the engaged state, the screws move one by one in the one direction independently. The release member has a contact portion that constitutes an end portion on the one-direction side. When the release member moves in the one direction as the screw moves, the contact portion contacts the object. The release member releases the engaged state. Thereby, even if the said rotary body is rotating, rotation of the said screw stops and the movement of this screw also stops. As a result, the three-dimensional structure of the present invention corresponds to the shape of the object without changing the shape of the object and controlling the rotation of the screw based on the digitized information. It can be changed into a shape. Further, after changing the shape on the one-direction side to a shape corresponding to the shape of the object, the plurality of screws may be used even when the shape on the one-direction side is changed to a shape corresponding to the shape of another object. There is no need for location information. Note that when the rotating body is rotated in the reverse direction in the engaged state, the screw is also rotated in the reverse direction, and the screw can be moved in the other direction.

Further, in the three-dimensional structure of the present invention, the screw assembly is a plurality of screw rows configured by arranging a plurality of the screws in a direction orthogonal to the one direction.
The rotating body preferably rotates each of the plurality of screws constituting the screw row for each screw row.

  Here, the rotating body may be movable to a position corresponding to each of the plurality of screw rows.

  By adopting a mode in which the rotating body rotates each of the plurality of screws constituting the screw row for each screw row, the shape on the one-direction side is changed to the shape of the object in turn for each screw row. It can be changed to a corresponding shape. Thereby, the shape of the one-dimensional side of the three-dimensional structure can be changed for each part. For example, the screw at a position corresponding to the human body in a state where the three-dimensional structure is applied to a bed and lies on its back After changing the shape of the row, it is also possible to change the shape of the screw row at a position corresponding to the body of a person who has turned over.

Furthermore, in the three-dimensional structure of the present invention, each of the plurality of screws has an engaged portion at an end portion on the other direction side,
The rotating body is
A screwdriver having an engaging portion that engages with the engaged portion;
A biasing member that biases the screwdriver in the one direction and engages the engaging portion with the engaged portion;
When the release member contacts the object when moving in the one direction as the screw moves, the release member stops moving in the one direction independently of the screw, and the one direction of the engaging portion The engagement state may be released by preventing movement to the position.

  By doing so, a sensor or the like for detecting that the object has contacted the contact portion is not required, and the engagement state can be released with a simple configuration.

Furthermore, in the three-dimensional structure of the present invention, the screwdriver has a second biasing member that biases the engaging portion in the one direction,
The release member releases the engagement state by blocking the movement of the engagement portion in the one direction against the urging force of the second urging member when contacting the object. Also good.

  When a pressing spring is used for the biasing member and the release member releases the engagement state by preventing the engagement portion from moving against the biasing force of the pressing spring. The biasing force with which the push spring biases the screwdriver changes depending on the position of the screw. For this reason, the force which prevents the movement of the engaging part necessary for the release member to release the engaged state varies. The screwdriver has the second urging member whose urging force is smaller than that of the urging member, for example, and the release member moves the engaging portion against the urging force of the second urging member. By adopting the mode of blocking, the force for blocking the movement of the engaging portion required for the releasing member to release the engaged state can be made constant.

  In the three-dimensional structure of the present invention, the screwdriver moves the engagement portion in the other direction against the urging force of the second urging member when the screwdriver moves in the other direction. You may have a 2nd cancellation | release member which cancels | releases an engagement state.

  Thus, when the screwdriver moves in the other direction, the engagement state is released by the second release member. For this reason, by adopting a mode in which the screw moved in the one direction is moved in the other direction in the engaged state, for example, the engagement state is released at an initial position before being moved in the one direction. It is also possible to return the screw to the initial position.

The three-dimensional modeling apparatus of the present invention that solves the above-mentioned object changes the shape on one side to the shape corresponding to the shape of the object by changing the partial protrusion length in one direction according to the shape of the object. A three-dimensional modeling apparatus including a three-dimensional modeling object and a power applying means,
The three-dimensional model is
Each of the plurality of screws can be independently rotated, and each of the plurality of screws can rotate independently of the one direction and the one by rotating. A screw assembly that can move independently of the other direction opposite to the direction;
A rotating body that rotates by being applied with power and rotates the screw in an engaged state engaged with the screw;
A contact portion that constitutes an end portion on the one-direction side, and includes a release member that moves along with the movement of the screw and releases the engagement state when the contact portion contacts the object. Is,

  According to the three-dimensional modeling apparatus of the present invention, the power is applied to the rotating body by the power applying unit, and the rotating body is rotated, whereby the shape of the object is digitized and the power based on the digitized information. The shape on the one-direction side in the three-dimensional modeling apparatus can be changed to a shape corresponding to the shape of the object without performing drive control of the applying means.

The molding apparatus of the present invention that solves the above-described object can change the shape on one side to a shape corresponding to the shape of the object by changing the partial protrusion length in one direction according to the shape of the object. A molding apparatus comprising a three-dimensional model that can be formed and a molding surface forming sheet,

The molding surface forming sheet is characterized in that a cavity is formed by being arranged at an end portion on the other direction side or an end portion on the one direction side in the screw assembly.

  Here, the cavity refers to a space having the same shape as the molded product.

  According to the molding apparatus of the present invention, the shape of the one-dimensional side of the three-dimensional modeled object is changed to the shape of the object without numerically converting the shape of the object or controlling the rotation of the screw based on the digitized information. The shape of the screw assembly on the other direction side can be changed to a shape obtained by inverting the shape on the one direction side. For this reason, by arranging the molding surface forming sheet at the end of the screw assembly on the other direction side, the screw assembly becomes a male mold and a cavity having a shape corresponding to the shape of the object is formed. A molded product corresponding to the shape of the object can be manufactured by filling the cavity with a molding material. Further, by disposing the molding surface forming sheet on the one-direction end of the screw assembly, the screw assembly becomes a female mold and a cavity having the same shape as the object is formed. A molded product having the same shape as the shape of the object can be produced by filling a molding material into the mold.

The engaging member 422 is disposed in a state where the retaining portion 4222 is urged by the second push spring 423 in the spring accommodating portion 421c, and the engaging plate 4221 is located in the leading end groove portion 421b. The engaging member 422 is biased by the second push spring 423 so that a one-side portion of the engaging plate 4221 is screwed and protrudes in one direction from the main body 421. Further, the engaging member 422 is configured such that when the engaging plate 4221 is pushed in the other direction against the urging force of the second pushing spring 423, the engaging plate 4221 is screwed and sunk into the main body 421.

  Each of the three screwdrivers 42 is inserted into a guide round hole 412a formed in the guide plate 412 in a state where the shaft 44 is inserted into the through-angle hole 421a from the other direction side. As a result, the screwdriver 42 rotates with the rotation of the handle 47 and the sprocket 43 and the shaft 44. Also. The screwdriver 42 is urged in one direction by the first push spring 45, and moves the screwdriver 42 in the other direction by pushing the screwdriver 42 in the other direction against the urging force of the first push spring 45. Can do. Hereinafter, a unit composed of the screwdriver 42, the sprocket 43, the shaft 44 and the first pressing spring 45 may be referred to as a screwdriver unit 40.

  In FIG. 2A, each of the three screwdrivers 42 is urged in one direction by the first pushing spring 45, and one end of the screwdriver 42 contacts the end of the screw 2 in the other direction. It touches. Note that a stopper (not shown) that restricts the movement of the rotating body 4 in the other direction is provided on the other direction side portion of the rotating body side frame 131. This stopper prevents the rotating body 4 from coming off the rotating body side frame 131 in the other direction due to the biasing force of the first push spring 45. Further, the engagement members 422 of the three screwdrivers 42 are engaged with the notches 22 of the three screws 2, respectively. That is, the engaging member 422 corresponds to an example of an engaging portion in the present invention, and the notch portion 22 of the screwdriver 42 corresponds to an example of an engaged portion in the present invention. Hereinafter, the state in which the engaging member 422 is engaged with the notch 22 may be referred to as an engaged state. In this engaged state, when the handle 47 is rotated in a predetermined direction and the screw driving unit 40 is rotated, the screw 2 is also rotated. As a result, the screw 2 moves in one direction. Hereinafter, the rotation direction of the handle 47, the screw driving unit 40, and the screw 2 that moves the screw 2 in one direction may be referred to as a normal rotation direction, and the direction opposite to the normal rotation direction may be referred to as a reverse rotation direction. is there. As the screw 2 moves, the release member 3 also moves in one direction. When the release member 3 comes into contact with an object (see FIG. 4 and the like) described later, the release member 3 stops moving independently of the screw 2. The screw 2 continues to rotate while the engagement state continues after the release member 3 stops moving, and the screw 2 moves in one direction. As described above, the two second pressing springs 423 are weaker than the biasing force of the first pressing spring 45 even when the respective biasing forces are combined. Therefore, the screw driver main body 421 moves in one direction together with the screw 2 while abutting against the other end of the screw 2 by the urging force of the first pushing spring 45, but the engaging member 422 is in contact with the contact portion 31. The movement stops upon contact with the end of the other direction. As a result, the engaging member 422 is gradually screwed against the urging force of the second pushing spring 423 and is immersed in the main body 421. Eventually, as shown in FIG. 2 (b), the end portion on one side of the screw 2 comes into contact with the end portion on the other direction side of the contact portion 31, and the notch portion 22 is formed by the other direction side portion of the shaft portion 32. It becomes a blocked state. As a result, the entire engaging member 422 is screwed and submerged in the main body 421, the engaged state is released, and the screwdriver 42 is idled with respect to the screw 2. As a result, the rotation of the screw 2 stops and the movement of the screw 2 in one direction also stops.

  Here, the second pressing spring 423 may be omitted, and for example, the engaging member 422 may be screwed and fixed to the main body 421. The engaging member 422 may be fixed to the outer peripheral portion of the screwdriver main body 421. However, in the aspect in which the engagement member 422 is screwed and fixed to the main body 421, the engagement state is released when the release member 3 resists the biasing force of the first push spring 45 and prevents the engagement member 422 from moving. The For this reason, the urging force by which the first push spring 45 urges the screwdriver 42 differs depending on the position of the screwdriver 42 in the front-rear direction, and the force necessary for the release member 3 to release the engaged state varies. As in the present embodiment, the second push spring 423 is provided separately from the first push spring 45 that urges the screwdriver 42 in one direction, and the release member 3 resists the urging force of the second push spring 423. By adopting a mode in which the engagement member 422 is prevented from moving, the force required for the release member 3 to release the engaged state can be made constant.

  In the present embodiment, the handle 47 is manually rotated to thereby rotate the sprocket 43. However, a power applying means such as a motor for applying power to the sprocket 43 may be provided. In the aspect provided with the power applying means such as a motor, the one provided with the shape transfer device 1 and the power applying means corresponds to the three-dimensional modeling apparatus in the present invention.

  4 and 5 are diagrams for explaining an example of a mode in which the shape on one side of the shape transfer apparatus shown in FIGS. 1 to 3 is changed to a shape corresponding to the shape of the object. 4 and 5, the left direction is one direction and the right direction is the other direction. In order to simplify the drawing, the screw side frame body 121, the rotating body side frame body 131, the frame 41 of the rotating body 4 and the chain 46 are omitted.

  4 and 5, for the sake of convenience, the shape of the shape transfer device 1 in one direction is shown using the object 5 having the first portion 51, the second portion 52, and the third portion 53 formed in a stepped shape. The case of changing to a shape corresponding to the shape of the first portion 51 to the third portion 53 of the object 5 will be described as an example. Further, in the shape transfer device 1 shown in FIG. 4 and FIG. 5, the screw 2, the release member 3, the screw driver unit 40, and each of the components arranged in the vertical direction are arranged in order from the top, In some cases, middle and lower terms are used for distinction.

  4 and 5, the rightmost screw row 20a among the plurality of screw rows 20a in the screw assembly 20 shown in FIG. 1 (a) and the most of the rotating body side frame 131 shown in FIG. 1 (b). The rotating body 4 inserted into the first guide part 131a on the right side is shown. The engaging members 422 of the three screwdrivers 42 are in an engaged state in which they are engaged with the notches 22 of the three screws 2.

  First, as shown in FIG. 4A, the object 5 is arranged on one side of the shape transfer device 1. In the shape transfer device 1, a shape on one side is formed by the contact portion 31. The object 5 is arranged so that the first portion 51 to the third portion 53 face the three contact portions 31.

  Next, the handle 47 is rotated in the forward rotation direction. The rotation of the handle 47 continues until all three screws 2 stop moving. When the handle 47 is rotated, as described above, the screw driving unit 40 rotates in the normal rotation direction, whereby the screw 2 rotates in the normal rotation direction, and the screw 2 and the release member 3 move in one direction. Since the rotation amounts of the three screws 2 are the same, the three screws 2 and the three release members 3 move together in one direction, and as shown in FIG. The first part 51 of the object 5 is contacted.

  Subsequently, the intermediate release member 3 and the lower release member 3 move in one direction together with the screw 2, and only the upper screw 2 moves in one direction with the upper release member 3 stopped. As a result, as shown in FIG. 4C, the screw driver main body 421 in the upper screw driver unit 40 moves in one direction in contact with the screw 2, but the engaging member 422 is attached to the shaft portion 32. The movement is blocked and the screw is turned into a state of being immersed in the main body 421, and the engaged state is released. As a result, the upper screw driving unit 40 is idled with respect to the upper screw 2, the rotation of the upper screw 2 is stopped, and the movement of the upper screw 2 in one direction is also stopped.

  The middle screw 2 and the lower screw 2 continue to rotate and move in one direction together with the respective release members 3, and as shown in FIG. 5A, the middle contact portion 31 is the second part of the object 5. 52 is contacted.

  Next, with the movement of the intermediate release member 3 stopped, the intermediate screw 2 moves in one direction, and the lower release member 3 and screw 2 move in one direction. Eventually, as shown in FIG. 5B, the engagement state between the intermediate screw 2 and the intermediate engagement member 422 is released, and the movement of the intermediate screw 2 stops.

  Subsequently, as shown in FIG. 5C, the engagement state between the lower screw 2 and the lower engagement member 422 is also released, and the movement of the lower screw 2 is also stopped. When the movement of all the screws 2 is stopped, the rotation of the handle 47 is stopped. As a result, a part of the shape on the one-direction side in the shape transfer device 1 changes to a shape corresponding to the first portion 51, the second portion 52, and the third portion 53 of the object 5.

  Next, the rotating body 4 is removed from the rotating body side frame body (not shown) in the other direction, and the removed rotating body 4 is inserted into the adjacent second guide portion 131b in the rotating body side frame body 131 shown in FIG. . When inserting the rotating body 4 into the second guide part 131b, the frame 41 is pushed in one direction with each of the three screwdrivers 42 abutting against the other end of the corresponding screw 2; As shown in FIG. 2A, the rotating body 4 is accommodated in the rotating body side frame 131. In this state, it is only necessary to restrict the rotator 4 from being detached from the rotator-side frame 131 by a stopper (not shown). Depending on the orientation of the notch 22 of the screw 2, the engaged state may not be achieved when the rotating body 4 is inserted into the second guide 131b. However, when the screwdriver unit 40 rotates and the engagement plate 4221 reaches a position corresponding to the notch 22, the engagement plate 4221 of the engagement member 422 biased by the second push spring 423 engages with the notch 22. The engagement state is established.

  Next, by performing the same operation as described above, each of the screws 2 of the adjacent high-position screw row 20a 'shown in FIG. 1A is moved in one direction. After the same operation is performed on all the screw rows 20a, the object 5 is moved to a position away from the shape transfer device 1. As a result, the shape on one side of the shape transfer device 1 can be changed to a shape corresponding to the shape of the object 5. As described above, according to the shape transfer device 1 of the present embodiment, the shape transfer device 1 is unidirectional without the numerical value of the shape of the object 5 or the rotation control of the screw 2 based on the digitized information. The shape can be changed to a shape corresponding to the shape of the object 5.

  When the shape on the one-direction side of the shape transfer device 1 is changed to a shape corresponding to the shape of the object 5 and then changed to a shape corresponding to the shape of another object, the screw 2 and the release member 3 are temporarily set. It is only necessary to move in the other direction and then perform the same operation as described above. In order to move the screw 2 and the release member 3 in the other direction, the handle 47 is rotated in the reverse direction in the engaged state. As a result, each screw 2 rotates in the reverse direction, and the screw 2 and the release member 3 move in the other direction.

  According to the shape transfer device 1 of the present embodiment, the contact portion 31 of the release member 3 is in contact with another object even when the shape on one side is changed to a shape corresponding to the shape of another object. Thus, the engaged state is released and the movement of the screw 2 in one direction stops. For this reason, the position information of each of the plurality of screws 2 is not required, and the shape on one side can be changed to a shape corresponding to the shape of another object.

  In addition, the shape transfer device 1 can be used as it is after changing the shape on one side to the shape corresponding to the shape of the object 5, or the rotary body side unit 13 can be removed and the screw side unit 12 can be used alone. it can. Furthermore, it can also be used in a state where the release member 3 is removed from the screw side unit 12.

  In the above-described embodiment, an example in which the direction connecting one direction and the other direction is made to coincide with the horizontal direction has been described as an example, but the direction connecting the one direction and the other direction is inclined with respect to the horizontal direction. Alternatively, the screw 2 may be moved in the vertical direction with the upper side in one direction and the lower side in the other direction. In the case where the upper side is in one direction, a plurality of contact portions 31 are located at the upper end portion of the shape transfer device 1, and the state in which the object 5 is placed on these contact portions 31, or these contact portions 31. The screw 2 is moved in one direction (upward) while the object 5 is supported above.

  Furthermore, in the above-described embodiment, an example in which the lengths in the front-rear direction of the plurality of contact portions 31 are the same has been described as an example, but the lengths in the front-rear direction of the plurality of contact portions 31 are different. Also good. For example, when the distance until the contact portion 31 comes into contact with the object 5 can be assumed in advance as in the lower release member 3 shown in FIGS. 4 and 5, the length of the contact portion 31 in the front-rear direction Set the length longer. Thereby, the moving distance of the release member 3 and the screw 2 is shortened, and the time for rotating the handle 47 can be shortened.

  The order of movement of the plurality of screw rows 20a shown in FIG. 1A is not limited, and the order is from the rightmost screw row 20a shown in FIG. 1A toward the left screw row 20a. For example, among the plurality of screw rows 20a shown in FIG. 1A, the screw row 20a at the center in the width direction is first moved, and then one row alternately left and right from the center in the width direction to the outside. The screw row 20a may be moved one by one.

  Further, in the present embodiment, the rotating body 4 is moved for each screw row 20a, and each of the screws 2 in one row of screw rows 20a is moved in one direction, but a plurality of screw rows 20a or screw assemblies 20 are You may employ | adopt the rotary body 4 provided with the screwdriver unit 40 corresponding to the screw 2. FIG. By doing so, the screws 2 in each of the plurality of screw rows 20a or the entire screw assembly 20 can be simultaneously moved in one direction.

  Next, a modification of this embodiment will be described. In the following description, the components having the same names as the component names in the embodiment shown in FIGS. 1 to 5 will be described with the reference numerals used so far, and redundant descriptions may be omitted.

  FIG. 6 is a diagram illustrating a screwdriver unit in a first modification of the present embodiment. FIG. 2A shows the screwing unit 40 in the engaged state. FIG. 2B is a cross-sectional view taken along line E-E in FIG. In FIG. 6, the first push spring 45 (see FIG. 5, etc.) is omitted for simplification of the drawing. Further, the screw 2 engaged with the engaging member 422 is omitted, and only the screw driving unit 40 is shown.

  As shown in FIGS. 6A and 6B, the screwdriver 42 of the first modified example includes a second release member 48. The second release member 48 includes a block 481, a hook bar 482, and a wire 483. As shown in FIG. 6B, the block 481 has a U-shape having a recess 481 a that is open in one direction, and is inserted into the through-angle hole 421 a of the screwdriver 42. The hook bar 482 extends in a direction perpendicular to the front-rear direction in the through-angle hole 421a. The hook bar 482 is integrally connected to the screwdriver 42. One end of the wire 483 is fixed to the end portion on the other direction side of the engaging member 422, hooked on the hooking bar 482, folded back in one direction side, and then the other end passes through the recess 481 a of the block 481. Fixed to the defining inner wall.

  FIG. 6C is a cross-sectional view showing a state in which the screwdriver shown in FIG. 6B is moved in the other direction, and FIG. 6D is a diagram showing still another screwdriver shown in FIG. It is sectional drawing which shows the state which moved to the direction and released the engagement state.

  In the state shown in FIGS. 6A and 6B, when the handle 47 (see FIG. 5 etc.) is rotated in the reverse direction, the screwdriver 42 moves in the other direction as shown in FIG. 6C. Then, the block 481 comes into contact with the shaft 44. In the state shown in FIG. 6C, the engagement state in which the engagement member 422 is engaged with the screw 2 (not shown) is maintained. Further, when the handle 47 is rotated in the reverse direction, the screw main body 421 moves in the other direction while the movement of the block 481 in the other direction is blocked by the shaft 44, and the position of the hook bar 482 is It moves to the bottom side of the recess 481a. As a result, the engagement member 422 is pulled by the wire 483 against the urging force of the second push spring 423, and the engagement member 422 is submerged in the recess 481a of the block 481 as shown in FIG. It becomes a state. As a result, the engaged state is released and the rotation of the screw 2 is stopped. By performing this operation on each of the plurality of screws 2, the plurality of screws 2 can be easily returned to the initial positions shown in FIG. As a result, after changing the shape of the unidirectional end of the shape transfer device 1, the shape of the unidirectional end of the shape transfer device 1 can be further changed without using the position information of the screw 2 in that state. Can be changed to another shape.

  When the screw 2 is moved in one direction from the state where the screw 2 is returned to the initial position shown in FIG. 6D, the rotating body 4 is detached from the rotating body side frame 131 (see FIG. 2 and the like). For example, the engagement member 422 is engaged with the notch 22 (see FIG. 2 and the like) of the screw 2 while being moved in the other direction by about 5 mm. Next, the handle 47 is rotated in the forward direction, and the screwdriver 42 is moved together with the screw 2 in one direction, for example, about 5 mm. Next, the rotating body 4 is housed in the rotating body side frame 131, and then the operation of moving the screw 2 in one direction as described above may be performed.

  Further, in this modification, the movement range of the screw 2 is from the position where the engaged state is released as shown in FIG. 6D to the position where the released member 3 comes into contact with the object and the engaged state is released. Limited during. At this time, by providing a sensor switch or the like for detecting whether or not the engaged state is released, for example, at the bottom of the tip groove portion 421b, the rotation amount of the screwdriver 42 (that is, the movement amount of the screw 2) is counted. Can do. Accordingly, the shape transfer device 1 can be used as a shape measuring instrument that measures and digitizes the shape of an object. The timing for measuring the shape of the object is as shown in FIG. 6D. After the screw 2 is returned to the initial position, the engagement member 422 and the screw 2 are engaged as described above, and then the release member 3 is engaged. FIG. 6 (d) shows the state until the state of contact with the object is released and the engagement state is released again, or in preparation for the next deformation after changing the shape of the end portion on one side of the shape transfer device 1. Until the screw 2 is returned to the initial position. As a procedure, the release member 3 comes into contact with the object and the engagement state is released, or, as shown in FIG. 6D, after the screw 2 is returned to the initial position, the engagement member 422 The counter is set to zero in the state where the screw 2 is engaged, and the rotation amount of the screwdriver 42 (that is, the movement amount of the screw 2) until the engagement state is released next is counted. Thereby, it is possible to measure the shape of the object together with the operation of changing the shape of the end portion on the one direction side of the shape transfer device 1, and it is possible to measure the shape of the object without increasing time and labor. .

  FIG. 7 is a diagram illustrating a release member, a screw, and a screwdriver unit in a second modification of the present embodiment. In the figure, the cross section of the screw 2 and the screwdriver 42 is shown. Moreover, the figure (a) has shown the engagement state, and the figure (b) has shown the state by which the engagement state was cancelled | released.

  As shown in FIG. 7A and FIG. 7B, a first annular groove 321 and a second annular groove 322 are formed on the outer peripheral portion of the shaft portion 32 of the release member 3 in this modification. Yes. The first annular groove 321 and the second annular groove 322 are formed at a predetermined interval in the front-rear direction in a portion on one side of the shaft portion 32. In this modification, the distance between the first annular groove 321 and the second annular groove 322 is set to be approximately the same as the length of the notch 22 in the screw 2 in the front-rear direction. The screw 2 is provided with a first latch member 23 made of spring steel on the inner wall that defines the through-hole 21. The first latch member 23 is located at one end portion of the through-round hole 21 and selectively engages with either the first annular groove 321 or the second annular groove 322.

  In the engaged state shown in FIG. 7A, the first latch member 23 is locked in the second annular groove 322. When the screwdriver unit 40 is rotated in the forward rotation direction in this engaged state, the screw 2 and the release member 3 move in one direction together with the screwdriver 42 as described above, and the contact portion 31 eventually comes into contact with the object. As a result, the release member 3 stops moving. When the screw 2 moves in one direction while the release member 3 is stopped, the first latch member 23 and the second annular groove 322 are unlocked, and as shown in FIG. 7B, the engagement member 422 and the screw 2 is released, and the first latch member 23 is locked in the first annular groove 321. Thereby, the state in which the engaged state is released, that is, the state in which the screw driving unit 40 is rotated and the idling state with respect to the screw 2 is maintained. Further, the first latch member 23 and the first annular groove 321 are unlocked by grasping the release member 3 and pulling the release member 3 in one direction or by pushing the release member 3 in one direction from the other direction side. The member 23 can be locked in the second annular groove 322. By doing so, the engaging member 422 can be engaged with the screw 2. Thereby, for example, after moving each of the plurality of screws 2 in one direction corresponding to the shape of the object, only the screw 2 whose position is to be changed is selected, and the above-described first latch member 23 is moved to the second annular shape. By performing the operation of engaging with the groove 322, the position of only the selected screw 2 can be changed. In addition to the aspect in which the shape on one side of the shape transfer device 1 is changed to a shape corresponding to the shape of the object, the operator releases the engaged state at a desired timing, so that the shape transfer device 1 The shape on the direction side can be arbitrarily formed. Specifically, while moving the screw 2 and the release member 3 in one direction, the operator pushes the release member 3 in the other direction at a desired timing, and as shown in FIG. 23 is locked in the first annular groove 321. Thereby, the engagement state of the engagement member 422 and the screw 2 is released, and the movement of the screw 2 in one direction stops. This operation may be repeated for each of the plurality of screws 2.

  Further, the shaft 44 is formed with a latch groove 441 in a portion on one side thereof, and the screwdriver 42 is provided with a second latch member 424 made of a spring steel material on the inner wall defining the through-angle hole 421a. ing. The 2nd latch member 424 is located in the edge part part of the other direction side in the through-angle hole 421a. As shown in FIG. 7B, when the screwdriver 42 moves in one direction and the portion of the shaft 44 inserted into the through-angle hole 421a becomes small, the second latch member 424 is engaged with the latch groove 441. The screwdriver 42 is prevented from falling off the shaft 44.

  Next, a bed provided with a shape transfer device according to an embodiment of the present invention will be described. This bed can be changed into a preliminary form for changing the shape on one side of the shape transfer device to a shape corresponding to the shape of the body and a use form for use as a bed.

  By moving the seat member 67 in this manner, the person P sitting on the seat member 67 can be moved in the width direction while rotating, and the person P can lie down while lying on the bed. Can be reproduced. In the present embodiment, the seat member 67 having a circular shape in plan view is employed, but a seat member having an elliptical shape in plan view that matches the body shape of the person P may be employed. This makes it possible to more faithfully reproduce the movement of the person P turning over. In addition, a plurality of seating surface members having different sizes may be prepared so that each body can be adapted to each body shape. Further, the configuration for moving the seat member 67 is not limited to the above-described configuration using the first string 681 and the second string 682, and for example, a configuration using a gear that moves in the width direction while rotating is also employed. be able to.

  The operation of changing the shape on the one-direction side in the shape transfer device 1 is performed when the seat surface member 67 shown in FIG. 8B is located at the center in the width direction of the first base 62 as shown in FIG. As shown in FIG. 2, the process starts after the person P faces one direction and sits on the seat member 67. When the person P sits on the seat member 67, the part from the waist to the head of the person P faces in one direction of the screw row 20a. This state of the person P corresponds to a state in which the person P lies on his / her back in the usage pattern of the bed 6 shown in FIG.

  In the present embodiment, as shown in FIGS. 9A and 9B, first, the rotating body 4 is arranged at a position corresponding to the screw row 20a at the center in the width direction, and the screw 2 of the screw row 20a is arranged. It moves it in one direction. As a result, the shape on one side of the shape transfer device 1 formed by the contact portion 31 of the screw row 20a at the center in the width direction is changed to a shape corresponding to the shape of the portion corresponding to the body axis of the person P. Yes.

  Here, a person's breathing is performed by moving the muscles of the chest, back, and abdomen to change the lung volume like an accordion. FIG.10 (c) is a figure which shows a mode when a person inhales and exhales. In FIG. 10C, a state when the person P exhales is indicated by a solid line, and a state when the person P inhales is indicated by a two-dot chain line.

  As shown in FIG. 10C, the curvature radius of the back increases when the person P inhales, and the curvature radius of the back decreases when the person P exhales. For this reason, in the existing bedding whose shape changes following the shape of the body of the person P, the bedding corresponding to the shape of the back that exhales and the curvature radius is small is expanded when inhaling. So you have to put extra power on your muscles. For this reason, it is desirable to move the screw row 20a in a state where the person P inhales, and to change the shape of the shape transfer device 1 in one direction to a shape corresponding to the body of the person P in the state where inhalation is inhaled. . By doing so, it is not necessary to put extra force on the muscles so as to push the bedding when the person P inhales, and it is possible to breathe easily. Further, since the person P takes a posture in which the back muscles are stretched in a state where the person inhales, the shape of the shape transfer device 1 on one side is changed to a shape corresponding to the body in a posture in which the person P stretches the back muscles. This makes it possible to correct postures such as preventing a spine without difficulty.

  Also, the importance of turning over is different between a healthy person who sleeps about 7 hours a day and a person who spends most of the day in bed, such as a sick person, bedridden elderly person, or disabled person. Even when 6 is used, by making it easy to turn over, it becomes easier to obtain good sleep and the usability of the bed 6 can be improved.

  FIG. 10A is a diagram for explaining a mode in which the shape on one side of the shape transfer device shown in FIG. 9B is changed to a shape corresponding to the body of a person who is turned over. The person P indicated by the alternate long and short dash line in FIG. 10A corresponds to the person lying on his back as shown in FIG. 9A and FIG. 9B, and the person P ′ indicated by the solid line turns to the right side. A person P ″ indicated by a two-dot chain line corresponds to a person who has turned over to the left. In FIG. 10A, the seat member is omitted to simplify the drawing.

  The seat surface member 67 is slightly rotated clockwise in plan view to slightly move the seat surface member 67 to the right in the width direction. In this state, the rotating body 4 is moved to the adjacent screw row 20a located on the right side in the width direction with respect to the screw row 20a at the center in the width direction, and is changed into a shape corresponding to the shape of the person P's body. This operation is repeated until the state of the person P 'corresponding to the state of turning over on the right side as indicated by the solid line in FIG. Next, the seating surface member 67 is rotated counterclockwise to return to the state of the person P corresponding to the state lying on his / her back as shown by the one-dot chain line in FIG. Next, the seat surface member 67 is slightly rotated counterclockwise to move the seat surface member 67 slightly to the left in the width direction. In this state, the rotating body 4 is moved to the adjacent screw row 20a located on the left side in the width direction with respect to the screw row 20a at the center in the width direction, and is changed into a shape corresponding to the shape of the body of the person P. This operation is repeated until the state of the person P ″ corresponding to the state of turning over to the left as indicated by the two-dot chain line in FIG. Thereby, the shape of the unidirectional side in the shape transfer apparatus 1 can be made into a shape in which a person can easily turn over. In the bed 6 of this embodiment, since it can be moved for each screw row 20a in which the screws 2 are arranged in the vertical direction (in the usage mode shown in FIG. 10B, the direction connecting the head and feet of the person P), The shape on the one-direction side in the shape transfer device 1 can be made to correspond to a state where a person has turned over. In particular, in the present embodiment, by rotating the seat member 67 in the width direction, the person P is rotated little by little, and the center of gravity of the person P is indicated as shown by a double arrow in FIG. The position (near the center of the plan view head) can be moved substantially linearly. Thereby, the vertical fluctuation of the center of gravity of the person P who turns over can be suppressed, and the shape can be more easily turned over. In the present embodiment, the screw rows 20a at both end portions in the width direction are aligned in the front-rear direction and the shape on one side thereof is adjusted to be flat.

  FIG.10 (b) is a figure which shows the usage condition of the bed provided with the shape transfer apparatus which is embodiment of this invention.

  First, the seat member 67, the first string 681 and the second string 682 are removed from the first base 62. Next, as shown in FIG. 10B, the second base 63 is disposed on the other direction side of the base frame 61, and the third base 64 is disposed on one direction side of the first base 62. Further, the mattress 65 is placed on the first base 62 and the third base 64. In this state, the rotating body side unit 13 is removed from the base frame 61, the screw side unit 12 is rotated in the other direction around the hinge 611, and the screw side unit 12 is supported by the second base 63. When the rotating body side unit 13 is supported on the second base 63, the plurality of contact portions 31 are positioned on the upper end side of the screw side unit 12, and the bed 6 is covered by covering the plurality of contact portions 31 with the cushion material 66. It becomes a usage form. Thereby, the bed 6 of the shape corresponding to the site | part from the waist | hip | lumbar to a head in the state which the person P fell on his back and turned over to the right and left can be obtained. Moreover, since the bed 6 has a portion corresponding to the shape of the head of the person P, it is not necessary to prepare a separate pillow.

  The contact portion 31 may be made of an elastic material, the cushion material 66 may be omitted, or the release member 3 may be removed and the screw assembly 20 may be covered with the cushion material 66. Furthermore, instead of the mattress 65, another shape transfer device may be arranged to form the bed 6 having a shape corresponding to the shape of the whole person P.

  Next, a molding apparatus including the shape transfer device 1 and a molding method using the molding apparatus, which are embodiments of the present invention, will be described.

The molding apparatus 7 also includes a molding surface forming sheet 71 and a support frame 72 as shown in FIG.

  As shown in FIG. 11A, in the molding method of the present embodiment, first, a screw assembly transfer process is performed (step S1). In the screw assembly transfer process, by rotating the screwing unit 40 of the rotating body 4 in the engaged state, the screw 2 is moved in one direction together with the release member 3, and the contact portion 31 is brought into contact with the body of the person P. In this step, the engagement state is released and the movement of the screw 2 is stopped. This screw assembly transfer step is a step of performing the same operation as the operation of changing the shape of the bed 6 in one direction described with reference to FIGS. 8, 9, and 10 (a).

  Next, in the state described with reference to FIG. 10 (b), the person P lies on the molding device 7 in the same form as the use form of the bed 6, and a verification process for verifying the sleeping comfort is performed (step S2). In the verification process, the sleeping comfort in the state of lying on the back, the sleeping comfort in the state of turning over, the ease of turning over, and the like are verified. In the verification process, the cushion material 66 shown in FIG. 8B may be omitted. If there is a part in which the person P feels dissatisfied in the verification process, the screw assembly transfer process is performed again. Here, it is not necessary to perform the entire screw assembly transfer process again, and only the portion of the screw 2 that the person P feels unsatisfied needs to be moved.

  In the verification process, when there is no part that the person P feels unsatisfied with, the cavity forming process is performed (step S3). In the cavity forming step, after the mattress 65 is removed from the state shown in FIG. 10B, the screw side unit 12 is rotated 180 degrees around the hinge 611 as shown in FIG. The aggregate 20 is inverted. It is preferable to remove the release member 3 from the screw 2 before rotating the screw side unit 12. Further, as in the second modification shown in FIG. 7, when the first latch member 23 adopts a mode in which the first latch member 23 is engaged with the first annular groove 321 of the release member 3, the release member 3 is removed from the screw 2.
