Description

  The present invention relates to a fastener used to prevent the lid from being opened in a handbag, a purse, a small case, or another storage device with a lid, and a storage device provided with such a fastener.

  The closure described in Patent Literature 1 includes a combination of a closure main body including a base and a closure, and a receiving bracket. The main body of the closure has a central portion protruding and a base formed to have a substantially convex shape, and both ends of the closure having a C-shaped plane are pivotally supported so as to be able to undulate. In the receiving fitting, a C-shaped closing tool and an insertion hole for inserting a distal end of a base pivotally supporting the base end thereof are formed. Both ends of the closure are pivotally supported via a pivot on a pivot portion formed in a convex shape at the center of the tip of the base via a pivot, and the lower surfaces and both side surfaces of both ends of the closure are It is resiliently supported by a support rod which is resiliently attached via a spring to support portions formed on both sides of the pivot portion. With such a configuration, the lower end side surface of the closing tool in the upright state or the falling state is always pushed up and supported by the supporting rod, so that even if an unnecessary external force is applied to the annular closing tool, the closing operation does not occur. It is said that an extremely stable use state can be maintained.

Japanese Utility Model Publication No. 5-91428

  However, in the closure described in Patent Literature 1, the user's clothes, fingers, and the like may slightly strongly touch the closure while using a handbag or the like using the closure. In this case, when an external force larger than the elastic force of the spring is temporarily applied to the closure, for example, the closure which has been in the lying state changes to the upright state, whereby the handbag lid is unintentionally opened. There is a risk of opening.

  In addition, when the bag is swollen due to storing an object in excess of an allowable amount in a handbag or the like, the lid is lifted up, and the closing metal fitting is easily erected naturally, whereby the lid is easily opened. There is also a problem.

  Accordingly, the present invention provides a fastener that selectively realizes a standing state and a falling state by changing the posture of a rotatable operation member, and can easily lock the falling state by a simple operation. It is another object of the present invention to provide a fastener in which the posture of the operation member is unlikely to change even when an external force is applied based on an unintended movement of the user, and a storage device provided with the fastener. It is a further object of the present invention to provide a storage device in which the folded state of the fastener is reliably maintained even when the storage amount in the storage device is increased.

  In order to solve the above problem, a fastener of the present invention includes a base for holding an elastic body so as to be elastically deformable, and an operation member rotatably supported around a support shaft provided on the base. The operating member selects between a standing state extending along a first direction as a deformation direction of the elastic body and a falling state extending along a second direction orthogonal to the deformation direction by rotation. Specifically, in both the standing state and the falling state, the body is urged in the first direction by the elastic force of the elastic body, thereby maintaining the standing or falling posture. By selectively displacing in the first direction, a first state capable of returning to an upright state by rotation and a second state in which rotation is restricted are selectively achieved.

  In the fastener of the present invention, the base includes a concave portion that accommodates the elastic body so as to be elastically deformable in the first direction, and the operation member controls the elastic force of the elastic body via a support body supported by the elastic body. It is preferable to receive.

  In the fastener of the present invention, it is preferable that the rotation of the operation member is restricted by abutting on the support in the second state.

  In the fastener of the present invention, the operating member includes a through-hole through which the operating member extends along the direction in which the support shaft extends, and the through-hole is inserted when the operating member is in the down state. It has two outer holes located at both ends in two directions, and an intermediate hole located between these two outer holes, and the operating member has a support shaft in one of the two outer holes. It is preferable that the first state be set when the support shaft is inserted, and the second state be set when the support shaft is inserted into the other of the two outer holes.

  In the fastener according to the present invention, the urging force of the elastic member against the operation member is more reduced when the support shaft is inserted into the intermediate hole than when the support shaft is inserted into one of the two outer holes. Is preferably larger.

  In the fastener of the present invention, when the support shaft is inserted through the through hole with the operating member in the down state, the distance between the support shaft and the elastic body in the first direction is such that the support shaft is inserted through the outer hole. It is preferable that when the support shaft is inserted through the intermediate hole, it is larger than when.

  In the storage device of the present invention, the fastener is provided on the main body of the storage device, and the lid of the storage device allows the operation member in the upright state to be inserted therethrough, and has an inner diameter smaller than the length of the operation member in the lying state. A hole is provided, and the lid is closed with respect to the main body by changing the operating member inserted into the hole in the upright state to the lying state.

  In the storage device of the present invention, it is preferable to lock the operation member by changing the operation member that has been inserted into the hole portion and is in the lying state from the first state to the second state.

  According to the present invention, the fall state can be easily locked by a simple operation, and even when an external force is applied based on an unintended movement of the user, a fastener in which the posture of the operation member is hard to change, and Thus, it is possible to provide a storage device having the same.

It is a perspective view showing the state where the lid of the purse as a storage using the fastener concerning the embodiment of the present invention closed. FIG. 2 is a perspective view showing a state in which a lid of the handbag of FIG. 1 is opened, and shows the fastener in an upright state. (A) is a perspective view showing the fastener in an upright state, and (b) is a cross-sectional view of the fastener taken along the line A-A 'in (a). (A)-(e) is sectional drawing which showed the fastener for every state.

  Hereinafter, a fastener according to an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing a closed state of a lid of a handbag 10 as a storage device using the fastener 30 of the present embodiment. FIG. 2 is a perspective view showing a state where the lid 12 of the handbag 10 of FIG. 1 is opened, and shows the fastener 30 in an upright state. FIG. 3A is a perspective view showing the fastener 30 in an upright state, and FIG. 3B is a cross-sectional view of the fastener 30 along the line A-A ′ in FIG. 4A to 4E are cross-sectional views showing the fastener 30 in each state. 4A shows a standing state, FIG. 4B shows an intermediate state between the undulating state and the falling state, FIG. 4C shows a first state in the falling state, and FIG. 4D shows a first state in the falling state. FIG. 9 shows a state intermediate between the state and the second state, and FIG. 10E shows a second state in the lying state.

  The fastener 30 of this embodiment is attached to the main body 11 of the handbag 10, as shown in FIG. This attachment is performed, for example, by inserting a leg (not shown) extending from the back surface of the fastener 30 into the main body 11 and screwing a set screw (not shown).

At the position corresponding to the fastener 30 when closed, an eyelet (eyelet) 20 (hole) penetrating the cover 12 in the thickness direction is provided in the cover 12. The eyelet 20 is made of a metal material such as brass, aluminum, stainless steel, zinc, or the like, and has a circular through-hole in a plan view. The through-hole penetrates the lid 12 in the thickness direction. The inner diameter of the through hole is smaller than the length of the operation member 50 provided in the fastener 30 (the length in the Z direction in FIGS. 3A and 3B) and the width of the operation member 50 (FIG. 3 (a), (b). More strictly, the inner diameter of the through hole is equal to the length from the longitudinal end portion 52 (FIGS. 3A and 3B) of the operating member 50 when supported by the support shaft 42 to the support shaft 42. Preferably, it is smaller than the minimum value. With such a configuration, the operating member 50 can be inserted into the eyelet 20 only in the upright state, and cannot be newly inserted into the eyelet 20 in the lying state.
Note that a configuration may be provided in which a hole that penetrates the lid 12 in the thickness direction is provided instead of the eyelet 20.

  When the operating member 50 of the fastener 30 is in the upright state as shown in FIG. 2, the operating member 50 can be inserted into the eyelet 20 of the lid 12, so that the lid 12 can be freely opened and closed with respect to the main body 11. Become. On the other hand, as shown in FIG. 1, when the operating member 50 is inserted into the eyelet 20 and the lid 12 is closed and then the operating member 50 is brought into the lying state, the operating member 50 comes into contact with the eyelet 20 provided on the lid 12. The operation of opening the lid 12 is limited, and the closed state of the lid 12 is maintained.

  As shown in FIGS. 3A and 3B, the fastener 30 includes a base 40, an operation member 50, a support body 60, and a spring 70 as an elastic body. It is preferable that the base 40 and the operation member 50 are made of a hard material having durability against contact with each other and between the operation member 50 and the support body 60. , Stainless steel and other metal materials are more preferable. The bearing body 60 is preferably made of a material having durability and rigidity in consideration of contact with the operation member 50, and is preferably made of a resin material from the viewpoint of manufacturability.

  In the following description, the direction of expansion and contraction (the direction of elastic deformation) of the spring 70 as an elastic body (the vertical direction (Z direction) in FIGS. 3B and 4A to 4E) is referred to as a first direction. Alternatively, the direction in which the operating member 50 in the lying state extends (the left-right direction (X direction) in FIGS. 3B and 4A to 4E), which is referred to as a vertical direction, extends in a direction orthogonal to the expansion and contraction direction. Called the second direction.

  As shown in FIGS. 3A and 3B, a pair of support portions 41, 41 extending along the up-down direction (Z direction) from the upper surface 40 a is provided on the upper portion of the base 40. These support portions 41, 41 face each other at a certain interval in a direction (Y direction) orthogonal to the first direction. An operation member 50 is arranged in a gap between the pair of support portions 41, 41. The operation member 50 has both ends fixed to the pair of support portions 41, 41, respectively, and is supported rotatably about a support shaft 42 extending along the Y direction.

  The operation member 50 includes a through hole 51 provided so as to penetrate along the width direction (Y direction), and the support shaft 42 of the base 40 is inserted into the through hole 51. The through-hole 51 includes two outer holes 51a and 51b at both ends in the longitudinal direction of the operation member 50, and an intermediate hole 51c located between the two outer holes 51a and 51b. Here, the longitudinal direction of the operation member 50 is a direction along the Z direction in the upright state as shown in FIG. 3B, and as shown in FIGS. 4C, 4D, and 4E. In the case of the laid-down state, the direction is along the X direction.

  The base 40 is further provided with a concave portion 43 recessed downward from the upper surface 40a between the pair of support portions 41, 41. The recess 43 has such a shape that the support body 60 can be displaced in the up-down direction while the outer surface of the base 61 is in contact with the inner wall of the recess 43.

  The support body 60 includes a columnar base 61 and a columnar shaft 62 extending downward from the lower surface 61 b of the base 61 concentrically with the base 61. One end of a resiliently deformable spring 70, which is a compression coil spring, is fixed to the lower surface 61b of the base 61 as an elastic member. The spring 70 is arranged so as to wind around the outer peripheral surface of the shaft portion 62, and extends below the lower end of the shaft portion 62 when no external force is applied. The other end of the spring 70 contacts the bottom surface 44 of the recess 43. Thereby, both ends of the spring 70 are held by the lower surface 61 b of the base 61 of the support body 60 and the bottom surface 44 of the concave portion 43, and the spring 70 is arranged so as to be able to expand and contract vertically. In other words, the bearing body 60 is elastically supported by the spring 70. By being guided on the inner surface of the concave portion 43, the direction of displacement of the support body 60 and the direction of expansion and contraction of the spring 70 are determined, so that the elastic force of the spring 70 acts on the operation member 50 efficiently.

  The operation member 50 is disposed on the upper surface 61a of the base 61 of the support body 60 so as to always contact the operation member 50 regardless of the state (posture). For this reason, a downward force is always applied to both the support body 60 and the spring 70 fixed to the lower surface 61b of the base 61 thereof. Therefore, the spring 70 is held in the recess 43 of the base 40 in a compressed state so as to be able to expand and contract. Further, the operation member 50 receives an upward elastic force from the spring 70. The magnitude of the downward force acting on the support body 60 and the spring 70 changes according to the state of the operation member 50 (see FIGS. 4A to 4E).

A change in the state of the operation member 50 will be described with reference to FIGS. 4A to 4E, the position of the upper surface 40a of the base 40 is indicated by a line BB '.
In the upright state shown in FIG. 4A, the operating member 50 extends so that the longitudinal direction is along the up-down direction (Z direction), and the rear end portion 54 in the longitudinal direction (the lower end in the upright state). The flat surface 55 is in contact with the upper surface 61a of the base 61. That is, the operation member 50 extends along the expansion and contraction direction (first direction) of the spring 70. As a result, the support body 60 and the spring 70 are suppressed downward from the operation member 50, so that the spring 70 contracts, and an upward force is urged against the operation member 50 by the elastic force of the spring 70 to expand. In this state, the operating member 50 maintains the upright posture.

  When the operation member 50 is rotated about the support shaft 42 in the direction D1 from the standing state shown in FIG. 4A, the operation member 50 is moved to the state shown in FIG. A falling state (first state) shown in FIG. In this lying state, the operation member 50 extends so that the longitudinal direction is along the X direction, and the side surface 53 (see FIG. 3B) substantially along the longitudinal direction is in contact with the lower surface 61b of the base 61. . At this time, the operation member 50 extends along a direction (second direction) orthogonal to the direction in which the spring 70 expands and contracts. As a result, the support body 60 and the spring 70 are suppressed downward from the operating member 50, so that the spring 70 contracts, and an upward force is urged against the operating member 50 by the elastic force of the spring 70 to expand. In this state, the operation member 50 is maintained in the posture of the lying state.

  Here, as can be seen by comparing FIG. 4 (a) and FIG. 4 (c), in the standing state (FIG. 4 (a)) and the falling state (first state) (FIG. 4 (c)), The position in the up-down direction where the upper surface 61a of the 61 abuts on the operation member 50 is different. More specifically, in the upright state, the spring 70 is contracted more because it is in contact with a lower position. Therefore, a stronger elastic force acts on the operation member 50 in the upright state (FIG. 4A). For this reason, it is easier to return from the lying state to the standing state by rotating the operating member 50 in the standing state in the direction opposite to the direction D1 than rotating the operating member 50 in the direction D1 to the falling state. 4 (c) is a state that can be returned to the upright state.

  Next, when the operation member 50 is moved in the D2 direction along the X direction from the lying state (first state) shown in FIG. 4C, the operation member 50 is moved through the state of FIG. Reaches the lying state (second state) shown in FIG. In this process, the position of the support shaft 42 in the through hole 51 is displaced from the outer hole 51a to the outer hole 51b via the intermediate hole 51c. In the lying state where the operating member 50 extends in the X direction (FIGS. 4C to 4E), the intermediate hole 51c is located above the two outer holes 51a and 51b, and thus the support shaft 42 is provided. When the position is in the intermediate hole 51c, the upward biasing force received by the operating member 50 by the elastic force of the spring 70 is larger than when the operation member 50 is in the two outer holes 51a and 51b. Further, when the support shaft 42 is inserted through the intermediate hole 51c, the support shaft 42 and the spring 70 in the first direction (Z direction) are more likely to be inserted than when the support shaft 42 is inserted into the outer holes 51a, 51b. The distance (shortest distance) is increasing. Therefore, in order to change the operation member 50 from the lying state (first state) in FIG. 4C to the lying state (second state) in FIG. In addition, it is necessary to move along the direction D2. Therefore, after reaching the second state, it is possible to prevent the state from easily returning to the first state even when an unintended external force is applied. Therefore, even if the handbag 10 is swelled due to the accommodation of an object larger than the allowable amount, the operation member 50 can be reliably prevented from returning to the first state or the upright state.

  Further, in the state shown in FIG. 4C, when the operation member 50 is to be rotated about the support shaft 42, the rear end 54 immediately contacts the upper surface 40 a of the base 40. Therefore, the rotation of the operation member 50 is restricted. Therefore, the operating member 50 is in a locked state that cannot be returned to the upright state by the rotation. Therefore, when the lid 12 of the handbag 10 is closed by bringing the operation member 50 into the lying state, the operation member 50 does not return to the upright state due to an unintended operation or the like, and the closed state is maintained. .

  On the other hand, in the second state shown in FIG. 4E, when the operation member 50 is moved in the direction D3 opposite to the direction D2 and returned to the first state shown in FIG. The operation member 50 is rotatable about the support shaft 42, is in the unlocked state, and can be returned to the upright state.

With the above configuration, the fastener according to the above embodiment has the following effects.
(1) By changing the posture of the operating member 50 that is rotatable about the support shaft 42, the standing state and the falling state can be selected, so that the closing and opening states of the fastener can be easily changed. Becomes
(2) Further, in the lying state, the operation member 50 can be returned to the upright state by a simple operation of displacing the operation member 50 in the second direction, that is, the direction orthogonal to the expansion and contraction direction of the spring 70 housed in the concave portion 43. The first state and the second state in which the rotation of the operation member 50 is restricted can be selected. As a result, it is possible to easily lock the lying state, and in this locked state, even if an external force is applied based on an unintended movement of the user or the like, the fastener of which the posture of the operation member 50 is hard to change is used. It became possible to realize.

Hereinafter, modified examples will be described.
In the above embodiment, in the second state of the laid-down state shown in FIG. 4E, the rear end 54 of the operation member 50 and the upper surface 40 a of the base 40 abut to rotate the operation member 50. Although it was limited, instead of or in addition to this, for example, if an engagement convex portion and an engagement concave portion are provided so that the base 40 and the operation member 50 are engaged with each other, This is preferable because the rotation of the member 50 can be more reliably limited.

  In the above embodiment, the spirit of attaching the fastener 30 to the handbag 10 as a storage device is described. However, the fastener in such an embodiment is not limited to the storage device, and may be, for example, a fastener (a clothing product). Button, etc.).

In the above-described embodiment, the spring 70, which is a compression coil spring, is used as the elastic body. However, the operating member 50 is urged in the first direction by the elastic force, and the posture of the operating member 50 in the standing state and the falling state is maintained. If possible, a configuration / form other than the compression coil spring may be used. Further, a configuration is also possible in which the elastic body is directly in contact with the operation member 50 without using the support body 60.
Although the present invention has been described with reference to the above embodiment, the present invention is not limited to the above embodiment, and can be improved or changed within the scope of the purpose of improvement or the concept of the present invention.

  As described above, the fastener according to the present invention can easily lock the falling state by a simple operation, and can maintain the posture of the operation member even when an external force is applied based on an unintended movement of the user. Is useful because it is difficult to change.
