  However, when the gripping portion of the storage case is gripped and lifted and carried, the locking portion may be unlocked and come off. , The possibility is higher.

  Accordingly, an object of the present invention is to provide a storage case having a locking portion that is not easily released even when the load of the storage case increases, and that locks stronger as the load increases.

The present invention includes an openable / closable lid portion, a container portion that accommodates an object to be accommodated, a latch portion that latches the lid portion and the container portion, and the latch portion is a latch member formed on the lid portion. The locking member formed on the side surface of the container portion is brought into contact with and locked, and the locking member formed on the lid portion is formed on the side surface of the container portion, which extends linearly downward from the lid portion. The locking member formed on the side of the container portion is pressed by the load of the container portion and the locking member formed on the lid portion is pressed against the lid portion. The contact portion of the locking member formed on the lid portion is inclined so that the formed locking member is pressurized in the direction of the side surface so that the closed state of the lid portion is maintained. It is a storage case.

  According to the storage case of the present invention, the locking portion that locks the lid portion and the container portion is such that the locking member formed on the lid portion is the container due to the load of the container portion (the load of the container and the load of the object). The pressure is applied in the direction of the side surface of the part, that is, in the direction of the side surface on which the locking member is formed. The larger the load, the stronger the locking. Therefore, the present invention has an effect that when the storage case is lifted, the locking portion is hardly released and there is less risk of detachment.

Further, when the storage case B is placed, it fits in a flat recess 12 provided on the upper surface of the lid portion 1 as shown in FIG. 1 and the like, and the upper surface of the lid portion 1 is in a substantially flat state where the grip portion 11 does not protrude. .

  The lid portion 1 has a flap portion 13. The flap portion 13 is formed at the center of the long side of the periphery of the lid portion 1. The flap portion 13 is a plate body formed integrally with the lid portion 1. The flap portion 13 has an inclined portion and a hanging portion (see FIG. 4 and the like), and is formed so that the inclined portion extends outward from the peripheral edge of the lid portion 1 and the hanging portion extends downward. A locking member 14 is formed on the inner surface of the flap portion 13.

  The locking member 14 constitutes a locking portion with the locking member 24 of the container part 2. The locking member 14 locks the lid portion 1 and the container portion 2 by being locked to the locking member 24. The locking member 14 is a protrusion that protrudes from the inner surface of the flap portion 13.

  The locking member 14 has a contact portion 14a. The abutting portion 14 a abuts on the abutting portion 24 a of the locking member 24 of the container portion 2. The contact part 14a is formed of an inclined surface. This inclined surface is an inclined surface having a lower proximal end and a higher distal end. In relation to the container part 2, it is an inclined surface that increases in the direction of the container part 2, that is, in the direction of the side surface on which the locking member 24 is formed.

  The locking member 14 has a slide portion 14b. This slide part 14b slides along the notch part 24b of the container part 2 when the cover part 1 is closed. The slide part 14b is formed below the contact part 14a. The slide part 14b is formed from the lower end of the flap part 13 to the lower end of the contact part 14a. The slide portion 14b is formed of an inclined piece that is inclined toward the tip of the contact portion 14a, and makes it easy to close the lid portion 1 when it is closed.

  The lid portion 1 has hooking portions 15 and 15 '. The hook portions 15 and 15 ′ are provided on both sides of the flap portion 13. The hooks 15 and 15 'are formed by cutting out the peripheral edge of the lid 1 so that the auxiliary stoppers 21 and 21' provided in the container part 2 are accommodated, and are formed on the auxiliary stoppers 21 and 21 '. Steps 15a and 15a ′ are provided on which the claw portions 21a are hooked.

  A groove portion 16 is formed on the back surface of the lid portion 1. The groove portion 16 is a portion into which a standing piece 22 erected on the opening periphery of the container portion 2 is fitted. The groove portion 16 controls the positional relationship between the lid portion 1 and the container portion 2 when the lid portion 1 is closed. The groove 16 is configured by an upright piece 16 a formed on the inner surface of the side surface constituting the lid portion 1 and the back surface of the lid portion 1.

  Next, the container part 2 will be described.

  The container part 2 is comprised by the bottom face and a side surface. That is, four side surfaces are formed around the rectangular bottom surface.

  The container part 2 has a locking member 24. The locking member 24 constitutes a locking portion with the locking member 14, and locks the lid portion 1 and the container portion 2. The locking member 24 is formed integrally with the container part 2 and is formed so as to protrude from the side surface of the container part 2.

  The locking member 24 includes a contact portion 24a, an upper plate portion 24b, and a back plate portion 24c. The contact portion 24a is a plate body that protrudes downward. The back plate portion 24c is a plate body that is parallel to the contact portion 24a.

  The tip of the contact portion 24 a contacts the contact portion 14 a of the locking member 14 and locks the lid portion 1 and the container portion 2.

  When the holding case B is lifted by grasping the grip portion 11, the tip of the contact portion 24a contacts and locks against the contact portion 14a due to the load of the container portion 2. The locked contact portion 24 a presses the inclined surface of the contact portion 14 a downward by the load of the container portion 2. When the tip of the contact portion 24a presses the inclined surface of the contact portion 14a, the pressing force acting on the contact portion 14a acts as a force acting in the direction of the side surface of the container portion 2 by the inclined surface, Press against the side of the container part 2. That is, the locking member 14 is pressurized in the direction from the proximal end to the distal end of the contact portion 14a.

  The locking member 24 has a notch 24d. The notch 24d is obtained by notching the surface of the locking member 24 so that an inclined surface is formed. The notch 24d slides the sliding portion 14b of the locking member 14 and guides the locking member 14 to the position shown in FIG.

  That is, when the locking member 14 comes into contact with the locking member 24 when the lid 1 is closed, the flap portion 13 formed integrally with the locking member 14 is elastically deformed outward. When the operation of closing the lid portion 1 proceeds and the locking member 14 reaches a position where it does not come into contact with the locking member 24, the outward deformation is restored and the locking member 14 is moved to the lower side of the locking member 24. Located (FIG. 4). In this process, when the locking member 14 comes into contact with the locking member 24, the cutout portion 24d is configured with an inclined surface so as to guide the slide portion 14b of the locking member 14 outward.

  The locking member 24 has a groove 25 that opens downward by the contact portion 24a, the upper plate portion 24b, and the back plate portion 24c. When the contact portion 24 a and the contact portion 14 a come into contact with each other due to the load of the container portion 2, the tip of the contact portion 14 a is positioned inside the groove 25 and the tip of the contact portion 14 a is placed in the groove 25. It is configured.

  The container part 2 has auxiliary stoppers 21 and 21 '. The auxiliary stoppers 21 and 21 ′ are provided on both sides of the locking member 24. The auxiliary stoppers 21 and 21 ′ are pivotally supported with respect to the container part 2 and are rotatably provided. Also, claws 21a and 21a 'are formed at the tips of the auxiliary stoppers 21 and 21'. The claws 21 a and 21 a ′ are hooked on the step portions 15 a and 15 a ′ of the hook portions 15 and 15 ′ of the lid portion 1.

  A standing piece 22 is formed on the periphery of the opening of the container portion 2 so as to stand upward. The standing piece 22 is fitted into the groove portion 16 formed in the lid portion 1.

  A pair of string hooks 23 and 23 ′ are formed on the opening periphery of the container 2. Since the string hooking portions 23 and 23 'are formed with rectangular string hooking holes, they can be used through shoulder straps (belts). In addition, hooks 23, 23 'are also formed with hook holes through which tools and the like are inserted and hooked.

  The case where the storage case of a present Example is lifted is demonstrated.

  First, the mounting state is shown in FIG.

  In the mounted state, the locking member 14 and the locking member 24 are not in contact (FIGS. 4 and 6). At this time, the distance (β) from the tip of the contact portion 14a to the tip of the contact portion 24a is about 0.78 mm. The distance (α) from the tip of the contact portion 14a to the outer surface of the contact portion 24a is about 4.5 mm. Further, the maximum vertical width (γ) of the locking member 14 is about 4.2 mm. As shown in FIG. 6, the abutting portion 24a of the locking member 24 is located above the abutting portion 14a. Specifically, the abutting portion 24a is located substantially at the center of the horizontal width of the abutting surface 14a. In the present embodiment, as shown in FIG. 4, the storage plate P can be attached inside the container portion 1.

  Next, FIG. 5 shows a state where the storage case B is lifted.

  When the storage case B is lifted, the contact portion 24a of the locking member 24 formed on the container portion 2 by the load of the container portion 2 presses the contact portion 14a of the locking member 14, and the pressed contact portion. The locking member 14 is pressurized in the side surface direction of the container portion 2 by the action of the inclined surface 14a.

  The magnitude of the pressurization is proportional to the load. As the load is applied, the locking member 14 moves in the direction of the side surface of the container and joins the locking member 24 as shown in FIG. That is, the contact portion 14a of the locking member 14 moves in the direction of the contact portion 24a of the locking member 24, and the proximal end of the contact portion 14a and the distal end of the contact portion 24a are joined. In other words, as a result of the locking member 14 being pressed by the locking member 24, the contact portion 24 is positioned at the proximal end of the contact portion 14 a, so that the locking is deeper.

  In such a storage case, in the locking portion that locks the lid portion and the container portion, the locking member of the lid portion is placed on the side surface of the container by the load of the container portion (the load due to the container and the object to be stored). Since the pressure is applied in the direction (the direction of the side surface on which the locking member is formed), the higher the load, the stronger the locking. Therefore, when the storage case is lifted, the locking portion is difficult to be released, and there is an effect that there is less risk of coming off.

  In addition, although the latching | locking part of a present Example has provided the latching member in the outer side of the cover part and the container part, it can also provide inward.

  Moreover, although this Example showed the case where a hinge part was provided, a hinge part is not provided but two sets of latching | locking parts can also be formed facing each other.

  Moreover, there is no restriction | limiting in the number of latching | locking parts, For example, a latching | locking part can also be paralleled.

  Moreover, in the mounting state of this embodiment, the locking member 14 and the locking member 24 are not in contact (FIG. 6), but may be in contact.
