Hereinafter, embodiments of a lid lock structure in a portable container such as a handbag according to the present invention will be described with reference to the accompanying drawings.
FIG. 1 is an exploded perspective view of a portable hand holding portion showing an embodiment of the present invention. FIGS. 2 and 3 are front views of only the upper half of the portable container. The unlocked state, FIG. 3 shows the locked state.

Although the use, specific shape, and structure of the portable container are not particularly limited, the portable container in the illustrated example is made of a synthetic resin having a handle, and a container body 1 and a lid that become a body container The container which is comprised with the body 2 and can be utilized for a portable accessory case is shown.
The container body 1 and the lid body 2 are pivotally supported on one side (not shown) as a lower position, and are provided with a lock structure for the hand 3 and the lid body 2 on the side surface opposite to the pivotal support position.

  The extender 3 is composed of a substantially gate-shaped extender main body 4 and a slide member 5 that is fitted into the extender main body 4 and is movable in the vertical direction. The extender main body 4 and the slide member 5 are respectively composed. One lender is formed in a state of being molded with a resin material and mounting both. Specifically, the cross-sectional shape of the hand main body 4 is substantially U-shaped with the upper side being opened, and the slide member 5 is a substantially gate-shaped top plate portion 5 a that closes the upper end open portion of the hand main body 4. And a vertical guide plate 5b that slides along the sliding side surface 4a of the hand main body 4, specifically, the inner side surface of the hand main body.

  The guide plate 5b of the slide member 5 is formed in a pair of longitudinal plates suspended from the left and right side edge portions of the bottom surface of the top plate portion 5a formed in a substantially portal shape, and is formed on the inner side surface of the handle main body 4 The sliding side surface 4a is in sliding contact. A recess 5c is formed on the outer surface of the central portion of the guide plate 5b as a finger hook. A substantially U-shaped notch 4c, 4c is formed from the upper side at the center of the left and right side walls 4b, 4b of the handle main body 4 (the position corresponding to the recess 5c of the slide member) whose inner side is a sliding surface. Forming. In other words, the open surface of the hand main body 4 is closed while the slide member 5 is pushed down, and the gripper shape is easy to grip as a whole, and the finger-hanging portion for pulling up the slide member 5 at the center of the left and right side surfaces is a notch portion. Formed by 4c and recess 5c.

Vertical ridges 12 are formed on both sides in the longitudinal direction of the inner surface of the side walls 4b, 4b of the hand main body 4. On the other hand, on both the left and right sides of the slide member 5, there are formed concave grooves 13 into which the ridges 12 are loosely fitted. As a result, the hand main body 4 and the slide member 5 are guided by the guide means at a plurality of positions of the sliding contact between the guide plate 5b and the sliding side surface 4a in the central portion and the fitting of the ridges 12 and the grooves 13 on the left and right sides. Therefore, the slide member 5 can be moved accurately and smoothly in the vertical direction.
Engaging convex portions 6 formed in a columnar shape in the drawing are projected outward from the left and right end portions of the slide member 5, respectively.

  The extender body 4 is pivotally attached to the container body 1. In order to pivotally attach the handle main body 4, a pair of support bases 8, 8 are formed integrally with the container main body 1 on the side surface of the container main body. The distance between the support bases 8 and 8 is slightly shorter than the inscribed dimensions of the left and right ends of the handle body 4 formed in a gate shape, and is supported inward on the inner side surfaces of both ends of the handle body 4. The shaft 9 is protruded, the shaft hole 14 is formed in the support base 8, and the support shaft 9 is fitted into the shaft hole 14, thereby supporting the hand body 4 on the container body 1.

  On the other hand, on the side surface of the lid body 2, two receiving seats 10 and 10 and one locking claw 11 are molded integrally with the lid body 2 so as to protrude from the opening edge toward the container body. That is, the receiving seat 10 is sized to enter on the extension line of the support shafts 9 and 9 of the handle main body 4 in the closed state, and the engagement recess 7 is provided on the surface thereof. The engagement concave portion 7 has a position and a size that engage with the engagement convex portion 6 formed on the slide member 5 in a state in which it does not move in the state where the slide member 5 is pushed down with the litter held up, that is, in the carrying state. In the illustrated embodiment, the opening edge rib 15 is formed in the circumferential direction in the upper part of the container body 1, but the opening edge rib at the entry position of the receiving seat 10 is cut off to secure the receiving passage 16 of the receiving seat. Yes.

  A locking claw 11 is projected at an intermediate position between the seats 10 and 10. The locking claw 11 functions to engage with the opening edge rib 15 of the container body 1 in the closed state and maintain the closed state. However, the engagement between the locking claw 11 and the opening edge rib 15 realizes a locking state equivalent to a temporary fixing, and it can be easily engaged and disengaged by placing a finger on the finger hooking portion 11a of the locking claw 11. Can be made. In other words, the structure is not intended to realize a strong engagement as in the locked state.

An example of the usage state of the portable container having the structure described above will be described.
In the state where the article is stored in the container body 1, the lid body 2 is closed and the locking claw 11 of the lid body 2 is locked to the opening edge rib 15 of the container body 1, the litter 3 is in the upper position. Raise the portable container so that. At this time, the slide member 5 of the hand 3 is moved upward with respect to the hand main body 4 as shown in FIG. In this state, when holding the hand 3 as shown in FIG. 5 and applying a force, the slide member 5 is pushed down as shown by an arrow, and the slide member 5 shown in FIG. 3 is pushed down. As shown, the hand 3 is held in a state where the slide member 5 is pushed down.

  In the state where the slide member 5 is pushed down with respect to the hand main body 4, the engagement convex portion 6 formed to protrude from the slide member 5 as shown in FIG. 3 is engaged to the seat 10 of the lid 2. Since it fits into the recess 7, the lid 2 cannot be opened unless the slide member 5 moves upward, and the lid 2 is maintained in a reliable locked state. In the illustrated embodiment, the engaging convex portion 6 has a cylindrical shape. By making the engagement convex part 6 into a columnar shape, the litter can be freely rotated in the carrying state, and a reliable engagement state is maintained.

  When the slide member moves upward with respect to the handle main body 4, the locked state of the lid body 2 can be released regardless of the posture of the portable container. Since the gripping force for holding the container acts as a force to push down the slide member 5 against the main body of the hand, the lid 2 is reliably maintained in the locked state when carrying the hand 3. Will be.

  The slide member 5 can be freely moved in the vertical direction with respect to the hand main body 4. However, the slide member 5 is not suitable during an operation for holding a portable container or when the hand is released from the hand. If the lock is released in advance, it may be inconvenient to handle. Therefore, in the illustrated embodiment, a click mechanism that can be locked with a light force at a position where the slide member is pulled up and a position where the slide member is pushed down is provided.

  As can be understood from FIGS. 7 and 9, the click structure of the slide member 5 is formed with a guide rib 17 in the vertical direction in the handle body 4, while a protrusion 18 that engages with the guide rib 17 is provided on the slide member 5. The protrusion 18 moves along the guide rib 17, and recesses 19 and 20 into which the protrusion 18 is fitted are provided at two positions, the upper position and the lower position of the guide rib 17. Therefore, at the upper end position where the slide member 5 is pulled up, the protrusion 18 engages and maintains the recess 19 at the upper position, and at the lower end position where the slide member is pushed down, the protrusion 18 is at the lower position. Engage with location 20 and maintain its position. Since the locking force by the click mechanism can be realized by the elastic force of the slide member 5 that is a gate shape, the engagement state can be easily released by the force that pulls up and pushes down the slide member 5.

  In a synthetic resin product, a click mechanism for temporarily fixing by a combination of protrusions and recesses is widely used. Therefore, although a click mechanism at an arbitrary position can be adopted in the present invention, in the illustrated embodiment, the sliding member is smoothly moved by the engagement of the longitudinal guide rib 17 and the protrusion 18, and the guide rib 17 By forming a retaining portion 21 at the upper end position of the sliding member 5, it also functions as a retaining structure for the slide member 5.

  FIG. 10 is a longitudinal sectional view showing another embodiment of the handle main body 4 and the slide member 5. In this embodiment, the guide plate 5b of the slide member 5 is suspended from the left and right edges of the top plate portion 5a at the central portion of the top plate portion 5a formed in a substantially portal shape, The sliding side surface 4a is formed in sliding contact. The sliding side surface 4a of the hand main body 4 with which the inner side surface of the guide plate 5b is in sliding contact has a portion corresponding to the width of the guide plate 5b as a flat vertical surface that is one step lower, and the side surfaces of the hand main body other than the sliding side surface 4a. And the outer surface of the guide plate 5a is flush with each other. That is, the open surface of the hand main body 4 is closed in a state where the slide member 5 is pushed down, so that the hand is shaped so as to be easily gripped as a whole.

  The lid lock structure in the portable container according to the present invention is not limited to the illustrated embodiment. For example, the lid lock structure is implemented by providing an engaging convex portion on the lid and an engaging concave portion on the slide member of the litter. You can also. Also, the specific slide structure of the lender main body and the slide member can be changed to other than the illustrated example. In short, as the gripper grips the gripper body and the slide member is relatively pulled, the slide member is pushed down, and a part of the slide member and a part of the lid in the closed state are engaged and locked. Anything can be used.
