  The forming groove 22 is formed as a recess having a longitudinal cross section (in other words, a cross section orthogonal to the opening surface) corresponding to the shape of the upper surface of the support member 3 and a portion in the vicinity thereof.

  The molding groove 12 of the first mold 10 and the molding groove 22 of the second mold 20 are formed at mutually opposing positions in a state where the first mold 10 and the second mold 20 are combined. The two forming grooves 12 and 22 constitute a cavity 19 into which the material of the support member 3 is poured to form the support member 3.

  The pressing tool 30 has a main body portion 31 and a plurality of film pressing portions 32 formed in the form of transparent teeth (in other words, as a space tooth row) rising from the main body portion 31. In addition, the pressing tool 30 can be formed of, for example, the same material / material as the first mold 10 and the second mold 20, and can exhibit sufficient heat resistance and strength. For example, it may be formed of a material / material different from the first mold 10 and the second mold 20.

  In a state where each of the plurality of film pressing portions 32 is inserted into each of the plurality of through holes 14 formed in the forming groove 12 of the first mold 10 and enters the forming groove 12, the pressing tool 30 It is used in combination with one type 10.

  The plurality of through holes 14 in the forming groove 12 of the first mold 10 and the plurality of film pressing portions 32 of the pressing tool 30 are such that each film pressing portion 32 is inserted into each of the through holes 14 In a state where the first mold 10 and the pressing tool 30 are used in combination, the respective positions are formed or provided so as to coincide with each other.

  Therefore, the plurality of film pressing parts 32 intermittently surround the film-like member installation base 11 of the first mold 10 in a state where the first mold 10 and the pressing tool 30 are used in combination as a whole. Is formed.

  Each film pressing portion 32 has a body portion 32a which is a portion standing up from the main body portion 31, and a film pressing claw 32b formed by bending the tip end portion of the body portion 32a into a hook shape.

  Each film pressing claw 32b protrudes from the body portion 32a so as to stick out above the film-like member pressing base 15 of the first mold 10 (that is, bent toward the film-like member installation base 11) Is formed so as to protrude toward the side of the film-like member pressing base portion 15).

  Here, the contour shape of the film-like member 2 in a plan view and the contour shape of the region surrounded by the body portions 32 a of the plurality of film pressing portions 32 are adjusted to match or substantially match. Furthermore, the outline (in other words, the peripheral edge) of the film-like member 2 in a plan view is adjusted to be located (in other words, present) in the forming groove 12 of the first mold 10.

  The pressing member 30 extends the film-like member of the first mold 10 so that the degree of protrusion of the film pressing portion 32 from the through hole 14 of the first mold 10 changes by a drive mechanism not shown. It is configured to be movable relative to the first mold 10 so that the degree of separation of the film pressing claws 32b of the film pressing unit 32 with respect to the facing surface of the pressing base unit 15 changes.

  The specific content of the manufacturing method of the buttocks support structure 1 is demonstrated below.

  Here, in the description of the present invention, regarding the direction of movement of the presser 30 with respect to the first mold 10, the upward direction in FIGS. 1 and 6 to 13 is referred to as "the direction in which the film pressing portion 32 protrudes" Is referred to as "the direction in which the film pressing portion 32 pulls in".

  As a procedure of a method of manufacturing the buttocks support structure 1, first, the opposing surface of the film member pressing base portion 15 and the film pressing claw 32b of the film pressing portion 32 are separated to create a gap between them. The relative position of the presser 30 to the first mold 10 is adjusted by the drive mechanism (not shown) in the direction in which the membrane pressing portion 32 projects.

  The plurality of locking holes 2a formed on the periphery of the film-like member 2 are spread (set in other words) the film-like member 2 spread on the film-like member installing base 11 of the first mold 10 The peripheral edge of the film-like member 2 is locked to the first mold 10 so that the locking pin 13 is inserted into each of the two (specifically, each of the plurality of locking holes 2a is each locking Locked to pin 13).

  At this time, a gap is generated between the film-like member pressing base portion 15 and the film pressing claw 32b of the film pressing portion 32 by the adjustment by the drive mechanism as described above, and the peripheral edge of the film-like member 2 Is intruded.

  The peripheral edge of the film-like member 2 spread and installed on the film-like member installing table 11 of the first mold 10 is locked by the locking pin 13 or the film of the film-like material pressing table 15 and the film pressing part 32 The relative position of the presser 30 with respect to the first mold 10 is adjusted by the drive mechanism in the direction in which the membrane pressing portion 32 retracts in a state of being inserted into the gap between the pressing claw 32 b and The peripheral edge of the film-like member 2 is pressed against the film-like member pressing base portion 15 by the film pressing claw 32b and stopped.

  As a result, the peripheral edge of the film-like member 2 is pressed against the opposing surface of the film-like member pressing base 15 by the film pressing claw 32 b and stopped (in other words, the film-like member pressing base 15). And held between the membrane pressing claw 32b and fixed).

  The film-like member 2 is spread and set (placed) on the film-like member installation base 11, and the peripheral edge of the film-like member 2 is engaged with the engagement pin 13 via the engagement hole 2a The second mold 20 is aligned and brought into close contact with the first mold 10 in a state of being held down (fixed) and fixed by the claws 32 b by a drive mechanism (not shown) (in other words, And be united).

  At this time, the locking pin 13 and the film pressing portion 32 (in particular, the film pressing claw 32b) are formed in the cavity 19 formed / configured by the molding groove 12 of the first mold 10 and the molding groove 22 of the second mold 20. And the film-like member supporting portion 16 and the peripheral edge (in particular, the outer end) of the entire perimeter of the contour of the film-like member 2 in a plan view is located.

  Here, in the present invention, the edge or edge of the film-like member 2 is positioned in the cavity 19 formed / configured by the molding groove 12 of the first mold 10 and the molding groove 22 of the second mold 20 ( In other words, there is a “membrane member including the mode in which the edge or the edge of the membrane member 2 is in contact with the surface defining the forming grooves 12, 22, ie the inner peripheral surface of the cavity 19). The two edges / edges are located / present in the inside of the forming grooves 12, 22.

  The locking pins 13 in the cavity 19, the film pressing portions 32, and the film-like member supporting portion 16 and the second mold 20 (specifically, the surfaces which define the forming grooves 22, ie, the cavities 19). The dimensions of each locking pin 13, each film pressing portion 32, the film-like member supporting portion 16, and the forming groove 22 are adjusted so that a gap is generated between the inner circumferential surface and the inner circumferential surface).

  With the first mold 10 and the second mold 20 combined, the material of the support member 3 (for example, a molten resin) is poured into the cavity 19. In addition, the flow path for pouring in the material of the support member 3 is provided in at least one of the 1st type | mold 10 and the 2nd type | mold 20 as a through-hole connected with the forming groove 12 and 22 (figure illustration Not).

  When the material of the support member 3 is poured into the cavity 19, the peripheral edge of the membrane member 2 is locked to the locking pin 13 via the locking hole 2a, and then the membrane pressing portion 15 and the membrane pressing Since the film-like member 2 is moved by the material to be poured and the peripheral edge of the film-like member 2 is not flipped, since it is sandwiched and fixed between the claw 32 b and the film-like member 2 The state in which the peripheral edge (in particular, the outer end) of the entire perimeter of the contour in plan view is kept at the predetermined position in the cavity 19 is reliably maintained.

  At this time, the film-like member supporting portion 16 provided in the forming groove 12 functions as a mechanism for stabilizing the position of the film-like member 2 in the forming groove 12.

  Specifically, when the film-like member supporting portion 16 is not present, the film-like member 2 is installed on the film-like member installing base 11, and the first mold 10 and the second mold 20 are combined. When the material of the support member 3 is poured into the cavity 19 in the state, the membrane member 2 (in particular, a portion other than the end of the edge, a portion inside the end of the edge in plan view of the membrane member 2) In some cases, the film-like member 2 may stick to the film-like member installation stand 11 (FIG. 11).

  Then, when the film-like member 2 (in particular, a portion inside the edge of the edge in the plan view of the film-like member 2 excluding the edge of the edge) has become closer to the film-like member installation base 11 It is considered that the film-like member 2 in the state formed as the buttocks supporting structure 1 is stretched in a shape other than the desired shape or wrinkles or slacks occur in the film-like member 2 or the like. And the membrane-like member 2 in a state of being formed as the buttocks support structure 1 (in particular, a portion of the membrane-like member 2 other than the edge, the inner side than the edge of the edge in plan view) is the support member 3. It is also conceivable to expose on the surface (in particular, the upper surface or the side surface).

  On the other hand, when the film-like member supporting portion 16 is provided in the forming groove 12, when the material of the supporting member 3 is poured into the cavity 19, the film-like member 2 is in the direction of the film-like member installation stand 11. Even if it tries to go down, the film-like member support part 16 can not approach to the film-like member installation stand part 11 because it becomes an obstacle (in other words, it is a support (support)) Figure 12). For this reason, the peripheral portion of the membrane member 2 (particularly, the portion other than the edge end, which is the portion inside the edge end in the plan view of the membrane member 2 in plan view) has a stable position in the forming groove 12 The peripheral end of the membrane 2 is reliably positioned in the groove 12.

  Then, after the material poured into the cavity 19 is solidified, the second mold 20 is pulled away from the first mold 10, and the frame-like support member 3 is integrally formed along the periphery of the film-like member 2 The buttocks support structure 1 in the closed state is removed from the first mold 10.

  When the buttocks support structure 1 is removed from the first mold 10, the facing surface of the film member pressing stand 15 and the film pressing claw 32b of the film pressing unit 32 are separated and a gap is generated between them. Thus, the presser 30 is moved relative to the first mold 10 in the direction in which the membrane pressing portion 32 projects.

  Here, on the lower surface of the support member 3 of the buttocks support structure 1 removed from the first mold 10, the film pressing claw 32b of the film pressing unit 32 and the film-like member pressing base 15 are present during molding The film pressing member hole 3a, which is a space / hollow for the film pressing claw 32b to pass through when the buttocks support structure 1 is later removed from the first die 10, is a forming groove of the first die 10 at the time of forming. It is formed as an integral part (in other words, as communicating) with the mold cavity 3b which is a space / hollow where a part of a part which divides 12 existed. In A), the body portion 32a and the film pressing claw 32b of the film pressing portion 32 at the time of molding are represented as virtual objects, and a part of the first mold 10 for partitioning the molding groove 12 is The part exists while illustration of part itself is omitted It is represented as reference numeral 10 denoted by the brackets between).

  The film pressing member hole 3a is a film pressing claw 32b of the film pressing portion 32 which presses the periphery of the film member 2 against the film member pressing base 15 of the first mold 10 when the support member 3 is formed. Alternatively, it can be said that the space is a space in which the film-like member pressing base portion 15 is present.

  Then, the peripheral end of the film-like member 2 exists in the film-pressing member hole 3 a of the support member 3 (in other words, it is positioned).

  Here, in the present invention, the film pressing member hole 3a is formed in the support member 3 and is regarded as a portion constituting a part of the support member 3, and the edge or edge of the film member 2 is a film pressing member The presence / position in the hole 3 a is referred to as “the edge / edge of the membrane member 2 is present / located in the support member 3”.

  Further, at a portion where the locking pin 13 is provided, a locking member hole which is a space / hollow where the locking pin 13 exists at the time of molding divides the molding groove 12 of the first mold 10 at the time of molding It is formed as an integral part (in other words, in communication) with the mold cavity 3b which is a space / hollow where a part of the site existed.

  Furthermore, at the portion where the film-like member supporting portion 16 is provided, the supporting portion hole 3c, which is a space / cavity in which the film-like member supporting portion 16 exists at the time of molding, It is formed as an integral part (in other words, in communication) with the mold cavity 3b which is a space / cavity in which a part of the part which divides 12 exists.

  In addition, a pair of ribs 3d and 3e facing each other across the support hole 3c, which is a space / hollow in which the film-like member support 16 is present at the time of molding, are formed. Specifically, a first rib 3 d that protrudes downward is formed between the mold cavity 3 b and the support cavity 3 c, and between the support cavity 3 c and the membrane member installation base 11. A downwardly projecting second rib 3e is formed. It can be said that the pair of ribs 3d and 3e are double ribs formed by sandwiching the support hole 3c. The pair of ribs 3d and 3e are formed as a result of the manufacturing method and configuration specific to the present invention, and are not formed only for reinforcement.

  Here, with regard to the positional relationship between the locking pin 13, the membrane pressing portion 32, and the film-like member supporting portion 16 or the insert member 17, for example, engagement between the membrane pressing portions 32 adjacent to each other is The stop pin 13 is provided, and a position closer to the film-like member installation base 11 (in other words, the film-like member 2 and the support member 3) in the opposing surface view than the locking pin 13 in the vicinity. The film-like member supporting portion 16 / insert member 17 is provided in the vicinity (closest inside) than the locking pin 13 in the plan view of FIG. The film-like member support 16 / insert at a position closer to the film-like member installation base 11 (in other words, in the vicinity (closest in the near view) of the film-like member 2 and the support member 3 in plan view) The member 17 is provided It is considered to be or is.

  However, the positional relationship between the locking pin 13, the membrane pressing portion 32, and the membrane-like member supporting portion 16 or the insert member 17 is not limited to the above-described specific example, and the respective parts and members 13, 32, 16, 17, may be disposed.

  In addition, the locking pin 13 is provided between the film pressing parts 32 adjacent to each other, the film-like member supporting part 16 / insert member 17 is provided near the inner side than the locking pin 13, or By providing the film-like member supporting part 16 / insert member 17 in the vicinity near the inner side than the film pressing part 32, these cooperate better and cooperate to integrally form the film-like member 2 and the supporting member 3 Is done more properly. In particular, while the locking pin 13 is useful and effective as a mechanism for temporarily fixing the film-like member 2, the film pressing portion 32 can not be provided at the installation location of the locking pin 13. The film-like member 2 moves in the cavity 19 due to the inflow pressure of the material of the support member 3 in the non-location, but the film-like member supporting portion 16 / insert member 17 is provided in the vicinity of the locking pin 13 Since the position of the second member 2 can be stabilized, integral molding of the film member 2 and the support member 3 can be performed more appropriately.

  Thus, the frame-shaped support member 3 is integrally formed along the peripheral edge of the film-like member 2 (in other words, the film-like member 2 and the support member 3 are integrated) as an integrally molded article with a collar The support structure 1 is manufactured.

  The application of tension to the membrane member 2 to exert the elastic force required to constitute a supporting surface for supporting the body of the seated person installs the membrane member 2 on the first mold 10 When applying pretension, applying after applying integral by heat setting, or applying applying after attaching integral to the first mold 10 and applying after applying integral heat. Or in combination. Note that heat setting means applying pre-tension by causing the film-like member 2 to thermally shrink by bringing the heated heat source into contact with or close to the film-like member 2.

  The method of integrally forming the film-like member 2 and the support member 3 is not limited to the above-described injection molding method, and may be another method such as compression molding method or casting method. .

  According to the support structure, the chair, and the method for manufacturing the support structure configured as described above, the film pressing claw 32b is used to move the periphery of the film member 2 to the film member pressing stand 15 of the first mold 10. Since the pressing is performed (stopped), the peripheral end of the film-like member 2 is reliably present (in other words, positioned) in the inside of the support member 3 which is a frame (in other words, positioned) The peripheral edge of 2 can be prevented from coming out of the support member 3. For this reason, it becomes possible to manufacture the defect-free buttocks support structure 1 reliably.

  According to the support structure, the chair, and the method of manufacturing the support structure configured as described above, the peripheral edge of the film-like member 2 is surely present / positioned inside the support member 3 which is a frame. Alternatively, the buttocks support structure 1 may be completed by a single molding without performing secondary molding for covering the film-like member 2 which is exposed to the outside of the support member 3, and the support member 3 After forming the film, the film-like member 2 and the frame-like support member 3 are integrally formed without the need for a working step of cutting the peripheral end of the film-like member 2 outside the support member 3 concerned. Object 1 can be completed. For this reason, it becomes possible to manufacture a favorable buttocks support structure 1 efficiently, without going through an unnecessary effort and process.

  According to the supporting structure, the chair, and the method for manufacturing the supporting structure configured as described above, the film-like member supporting portion 16 is further provided in the forming groove 12 for forming the supporting member 3 which is a frame. Since the first mold 10 is used, the film-like member supporting portion 16 is functioned as a support / stitch to stabilize the position of the film-like member 2 in the forming groove 12 so as to form a film. The periphery of the member 2 is securely present / located inside the support member 3 so that the periphery of the membrane 2 (in particular, excluding the end of the edge, inside the edge of the edge in plan view of the membrane 2) It can be prevented that the part (the part) is exposed to the surface (especially, the upper surface and the side surface) of the support member 3. For this reason, it becomes possible to manufacture the defect-free buttocks support structure 1 reliably.
