[0043] Referring to FIGS. 1 to 6, a folding jig according to one embodiment of the present invention may include a fixed plate module (10), a folding plate module (20), and a rotational support module (30).

[0045] One side of the sample (S) is supported on the fixed plate module (10).

[0046] At both ends of the fixed plate module (10) facing the folding plate module (20), a concave fixed mounting portion for connection with the rotational support module (30) may be provided.

[0048] The folding plate module (20) is spaced apart from the fixed plate module (10). The other side of the sample (S) is supported on the folding plate module (20) so that it can move back and forth.

[0049] The folding plate module (20) may include a guide panel (21) spaced apart from the fixed plate module (10), a reciprocating slider (22) positioned to be reciprocally movable on the guide panel (21), a reciprocating member (23) coupled to the reciprocating slider (22) on one side of the guide panel (21) so as to support the other side of the sample (S), and a reciprocating support member (24) coupled to the reciprocating slider (22) on the other side of the guide panel (21).

[0050] The folding plate module (20) may further include an elastic member (25) that elastically reduces pressure on the reciprocating slider (22) in the forward direction of flow relative to the guide panel (21), while elastically reducing pressure on the reciprocating slider (22) in the rear direction of flow relative to the guide panel (21).

[0051] At both ends of the guide panel (21) facing the fixed plate module (10), a concave folding mounting portion for coupling with the rotation support module (30) may be provided.

[0052] A reciprocating guide (211) may be provided in the guide panel (21) along a flow direction perpendicular to a virtual line connecting a pair of pivot support modules (30). The reciprocating guide (211) may be formed to extend through the flow direction. A reciprocating slider (22) may be inserted into the reciprocating guide (211) so as to be able to reciprocate along the flow direction.

[0053] A guide panel (21) may be provided with a guide seating portion (212) corresponding to a reciprocating member (23) and a reciprocating support member (24). In one embodiment of the present invention, the guide seating portion (212) has a groove shape in which a plate-shaped reciprocating member (23) and a plate-shaped reciprocating support member (24) are seated, but it is not limited thereto and can be varied in various ways corresponding to the shapes of the reciprocating member (23) and the reciprocating support member (24), so that the reciprocating member (23) and the reciprocating support member (24) can be stably reciprocated while supported by the guide seating portion (212). The guide seating portion (212) can be divided into an upper seating portion in which the reciprocating member (23) is supported to be reciprocated along the direction of flow, and a lower seating portion in which the reciprocating support member (24) is supported to be reciprocated along the direction of flow.

[0054] A member mounting portion (213) may be formed in a recess in the guide panel (21) so that an elastic member (25) is movably mounted thereon. The member mounting portion (213) may be provided on one side or both sides relative to the reciprocating guide (211). An elastic coupling portion (214) in which the elastic member (25) is supported may be provided in the member mounting portion (213). The elastic coupling portion (214) can be modified in various ways depending on the shape of the elastic member (25).

[0055] The reciprocating slider (22) is coupled to the reciprocating guide (211) so as to be reciprocating.

[0056] Since the reciprocating slider (22) is provided with a reciprocating wing support portion that supports the wing portion of the elastic member (25), the elastic wing portion of the elastic member (25) is stably supported on the reciprocating slider (22), and the wing portion of the elastic member (25) can be prevented from being separated from the reciprocating slider (22).

[0057] Although the reciprocating member (23) is illustrated as having a plate shape, it is not limited thereto and can have various shapes such as a bar shape, and can move smoothly back and forth on the guide panel (21) while stably supporting the sample (S) on one side of the guide panel (21).

[0058] Although the reciprocating support member (24) is illustrated as having a plate shape, it is not limited thereto and can have various shapes such as a bar shape, and can move back and forth smoothly on the other side of the guide panel (21).

[0059] The elastic member (25) has elastic force and causes the reciprocating slider (22) to elastically depress with respect to the guide panel (21). The elastic member (25) may include a first member that elastically depresses the reciprocating slider (22) forward in the direction of flow with respect to the guide panel (21), and a second member that elastically depresses the reciprocating slider (22) backward in the direction of flow with respect to the guide panel (21).

[0060] In one embodiment of the present invention, the elastic member (25) may include a coil portion having elasticity and coupled to an elastic coupling portion (214), a fixed wing portion extending from the coil portion and coupled to an elastic support portion provided in a member seating portion (213), and an elastic wing portion extending from the coil portion and supported by a reciprocating wing support portion of a reciprocating slider (22) while spaced apart from the fixed wing portion.

[0061] By having the reciprocating member (23) and the reciprocating support member (24) respectively coupled to one side and the other side of the guide panel (21) so as to be reciprocally movable, the stress received by the folding plate module (20) as it is tensioned and compressed by the rotational support module (30) can be eliminated when the folding plate module (20) performs a folding operation on the fixed plate module (10) with the rotational support module (30) as the center. That is, in the unfolding folding operation, the stress received by the sample (S) can be eliminated as the reciprocating member (23) slides to the opposite side of the rotational support module (30) due to the tension force generated on the sample (S) supported by the reciprocating member (23) of the folding plate module (20). And in the folding operation, the stress received by the sample (S) can be eliminated as the reciprocating member (23) slides to the rotational support module (30) side due to the compression force generated on the sample (S) supported by the reciprocating member (23) of the folding plate module (20). And the sample(S) can prevent wrinkles from forming during the folding process.

[0062] The fixed plate module (10) can be formed with the same configuration as the folding plate module (20).

[0063] A pair of rotational support modules (30) are provided at each end of a mutually adjacent fixed plate module (10) and a folding plate module (20). The rotational support module (30) foldably connects the folding plate module (20) to the fixed plate module (10).

[0064] When the folding plate module (20) is folded based on the fixed plate module (10), the rotational support module (30) rotates based on the fixed plate module (10) in conjunction with the rotation of the folding plate module (20) based on the rotational support module (30), so the elastic member (25) is elastically deformed according to the folding operation, and the reciprocating member (23) moves back and forth in the guide panel (21), thereby satisfying the stress-free condition.

[0065] In addition, folding motion can be implemented with a preset radius of curvature without the need for additional jig modification or setting.

[0066] More specifically, as the mutually coupled reciprocating slider (22), reciprocating member (23), and reciprocating support member (24) reciprocate with respect to the guide panel (21), the elastic member (25) supported at the front and rear of the reciprocating slider (22) is elastically deformed. Then, according to the interaction of the elastic member (25) supported at the front and rear of the reciprocating slider (22), the reciprocating movement of the reciprocating slider (22) in the reciprocating guide (211) provided in the guide panel (21) can be facilitated, and stress acting on the sample (S) is prevented. Therefore, since the folding jig according to one embodiment of the present invention implements a reciprocating movement structure and an elastic support structure during the folding operation, it can satisfy stress-free conditions regarding stress acting on the sample (S).

[0067] The rotational support module (30) can connect the fixed plate module (10) and the folding plate module (20) so that they can be folded together. The rotational support module (30) is formed as a pair and can be provided at each mutually adjacent end between the fixed plate module (10) and the folding plate module (20). This rotational support module (30) can form a first fixed part (31), a second fixed part (32), a first gear part (33), a second gear part (34), and a hinge part (35).

[0068] The first fixing part (31) can be fixedly coupled to one end of the fixing plate module (10). The first fixing part (31) can form a first bracket (31a), a first extension part (31b), a first guide hole (31c), and a first guide groove part (31d).

[0069] The first bracket (31a) can form the body of the first fixing part (31). The first bracket (31a) may have a flat plate shape.

[0070] The first extension (31b) can be extended in a straight line from one of the two sides of one end of the first bracket (31a).

[0071] The first guide hole (31c) may be an elongated hole penetrating the end of the first extension part (31b) in a rounded shape. It may be movably hinge-coupled to either of a pair of hinge guides (35c) formed in the hinge part (35). That is, the first fixing part (31) is hinge-coupled to the first guide hole (31c) and the hinge guide (35c), so that the first fixing part (31) can hinge-move around the hinge part (35), and the first fixing part (31) can slide around the hinge part (35) by the length of the first guide hole (31c). Therefore, when the folding plate module (20) performs a folding operation on the fixing plate module (10) around the rotational support module (30), the stress received by the folding plate module (20) as it is tensioned and compressed by the rotational support module (30) can be eliminated. In detail, when the first fixing part (31) slides around the hinge part (35) due to the tensile force generated on the sample (S) supported by the reciprocating member (23) of the folding plate module (20) during the unfolding folding operation, the folding plate module (20) coupled to the first fixing part (31) slides together with the first fixing part (31) toward the opposite side of the rotational support module (30), thereby relieving the stress received by the sample (S). Also, when the first fixing part (31) slides around the hinge part (35) due to the compressive force generated on the sample (S) supported by the reciprocating member (23) of the folding plate module (20) during the folding operation, the folding plate module (20) coupled to the first fixing part (31) slides together with the first fixing part (31) toward the rotational support module (30), thereby relieving the stress received by the sample (S). And the sample(S) can prevent wrinkles from forming during the folding process.

[0072] The first guide groove (31d) can be slidably connected to the other end of the first gear part (33). The first guide groove (31d) can be formed concavely through one end of the first bracket (31a) and continuously extend to the other end of the first bracket (31a). That is, the first gear part (33) can be seated in the first guide groove (31d) which is formed concavely while penetrating one end of the first bracket (31a) along the first guide groove (31d). Furthermore, the first guide groove (31d) can guide the movement of the first gear part (33) so that it does not deviate from the movement path of the first gear part (33) when the first gear part (33) slides.

[0073] The second fixing part (32) can be fixedly coupled to the other end of the fixing plate module (20) adjacent to one end of the folding plate module (10). The second fixing part (32) can form a second bracket (32a), a second extension part (32b), a second guide hole (32c), and a second guide groove part (32d).

[0074] The second bracket (32a) can form the body of the second fixing part (32). The second bracket (32a) may have a flat plate shape.

[0075] The second extension (32b) can be extended in a straight line from one of the two sides of the end portion of the second bracket (32a).

[0076] The second guide hole (32c) may be an elongated hole penetrating the end of the second extension part (32b) in a rounded shape. It may be movably hinge-coupled to either of a pair of hinge guides (35c) formed in the hinge part (35). That is, the second fixing part (32) is hinge-coupled to the second guide hole (32c) and the hinge guide (35c), so that the second fixing part (32) can hinge-move around the hinge part (35), and the second fixing part (32) can slide around the hinge part (35) by the length of the second guide hole (32c). Therefore, when the fixing plate module (10) performs a folding operation on the folding plate module (20) around the rotational support module (30), the stress received by the fixing plate module (10) as it is tensioned and compressed by the rotational support module (30) can be eliminated. In detail, when the second fixing part (32) slides around the hinge part (35) due to the tensile force generated on the sample (S) supported by the fixed plate module (10) during the unfolding folding operation, the fixed plate module (10) coupled to the second fixing part (32) slides together with the second fixing part (32) toward the opposite side of the rotational support module (30), thereby relieving the stress received by the sample (S). Also, when the second fixing part (32) slides around the hinge part (35) due to the compressive force generated on the sample (S) supported by the reciprocating member (23) of the fixed plate module (20) during the folding operation, the fixed plate module (20) coupled to the second fixing part (32) slides together with the second fixing part (32) toward the rotational support module (30), thereby relieving the stress received by the sample (S). Additionally, it is possible to prevent wrinkles from forming on the sample (S) during the folding process.

[0077] The second guide groove (32d) can be slidably connected to the other end of the second gear part (34). The second guide groove (32d) can be formed concavely through one end of the second bracket (32a) and continuously extend to the other end of the second bracket (32a). That is, the second gear part (34) can be seated in the second guide groove (32d) which is formed concavely while penetrating one end of the second bracket (32a) along the second guide groove (32d). Furthermore, the second guide groove (32d) can guide the movement of the second gear part (34) so ​​that it does not deviate from the movement path of the second gear part (34) when the second gear part (34) slides.

[0078] The first gear part (33) can be slidably connected to the first fixed part (31) at the other end. Additionally, the first gear part (33) can form a toothed gear around the end portion.

[0079] The second gear section (34) can be slidably connected to the second fixed section (31) at the other end. The second gear section (34) can form a toothed gear around the end portion. The second gear section (34) can be geared by engaging the toothed gear of the end portion with the toothed gear of the first gear section (33).

[0080] The hinge portion (35) can hinge-connect the first gear portion (33) and the second gear portion (34), respectively. The hinge portion (35) can form a support portion (35a), a column portion (35b), a hinge guide (35c), a first hinge shaft (35d), and a second hinge shaft (35e).

[0081] The support portion (35a) can form the body of the hinge portion (35). The support portion (35a) may be in the shape of a flat plate.

[0082] The column portion (35b) forms a pair and can be erected vertically from each end of the support portion (35a).

[0083] The hinge guide (35c) is formed as a pair, and can be convexly extended from one of the pair of column parts (35b) toward the opposite side facing each other.

[0084] The first hinge shaft (35d) can be connected by penetrating both one end of the first gear part (33) and a pair of pillar parts (35b). That is, the first hinge shaft (35d) can be the rotation axis of the first gear part (33).
