【Example】
Hereinafter, preferred embodiments of the interchangeable lens storage case according to the present invention will be described in detail with reference to the accompanying drawings.
First, the interchangeable lens stored in the interchangeable lens storage case according to the present invention will be described. As shown in FIG. 6, the interchangeable lens 1 is an interchangeable lens for a large format camera having a built-in shutter charging mechanism and an aperture mechanism. The interchangeable lens 1 has a rectangular shape on a front frame 4 connected to a camera body 2 via a bellows 3. It is detachably attached via a lens seat plate 5. The interchangeable lens 1 is supported by a lens seat plate 5. The lower edge of the lens seat plate 5 is placed on a hook 6 on the front frame 4, and the upper portion is pressed against the camera body 2 by a buckle 7. As a result, it is fixed to the camera side. Further, the interchangeable lens 1 is stored in a storage case while being supported by the lens seat plate 5.
[0011]
FIG. 1 is a perspective view showing the appearance of a storage case for an interchangeable lens according to the present invention.
As shown in FIG. 1, the storage case 10 is formed in a rectangular parallelepiped box shape by a case body 12 and a lid 14. As shown in FIG. 2, the case main body 12 and the lid 14 are connected at one short edge thereof by a hinge 16 so that the lid 14 can be freely opened and closed by the hinge 16. Supported. Further, a convex metal piece 18 constituting one stopper is fixed to the case body 12 side, and a concave metal piece 20 constituting the other stopper is provided on the lid 14 side. The concave metal piece 20 is fixed to a tongue piece 22 extending from the short side edge of the lid 14, the lid 14 is closed and fitted to the convex metal piece 18. Thereby, the opening of the lid 14 is prevented. The case body 12, the lid 14, the hinge portion 16, and the tongue 22 of the present embodiment are integrally formed of a synthetic rubber or plastic elastomer and have elasticity and impact resistance.
[0012]
In FIG. 2, on the inner wall surface of the case body 12, a plurality of concave grooves 24 are formed at regular intervals. The groove 24 has a bottom groove 24A on the inner wall of the bottom surface of the case main body 12 along the longitudinal direction of the case main body 12, and a wall groove 24B connected to both ends of the bottom groove 24A and extending in the depth direction of the case main body 12, 24C and is formed integrally with the case body 12.
[0013]
The length of the bottom groove 24A and the height of the wall grooves 24B and 24C are set so that the lens seat plate 5 supporting the interchangeable lens 1 can be held in the case main body 12, that is, the bottom groove 24A The length is set so that the lower edge 5A of the seat plate 5 can be fitted, and the height of the wall grooves 24B and 24C is set so that the left edge 5B and the right edge 5C of the lens seat plate 5 can be fitted. Accordingly, the interchangeable lens 1 pushes the left and right edges 5B, 5C of the lens seat plate 5 along the wall grooves 24B, 24C, and fits the lower edge 5A of the lens seat plate 5 into the bottom groove 24A, thereby forming the case body. 12 (see FIG. 3). A plate indicated by reference numeral 26 is a protector plate for protecting the front surface of the interchangeable lens 1 when the interchangeable lens 1 is stored. The protector plate 26 is formed to have the same size as the lens seat plate 5. After the interchangeable lens 1 is housed in the case main body 12, it is fitted into the groove 24 corresponding to the front surface of the interchangeable lens 1 (see FIG. 3).
[0014]
In FIG. 2, a plurality of concave grooves 28 are formed at regular intervals on the inside of the lid 14. The grooves 28 are formed at intervals equal to the intervals at which the grooves 24 are formed so as to communicate with the grooves 24 on the case body 12 side when the lid 14 is closed. The groove 28 includes an upper groove 28A extending in the longitudinal direction of the lid 14 on the inner wall of the upper surface of the lid 14, and wall grooves 28B and 28C provided at both ends of the upper groove 28A and extending in the depth direction of the lid 14. 14 and are integrally formed. That is, when the lid 14 is closed, the bottom groove 28A fits into the upper edge 5D of the lens seat plate 5, the wall groove 28B fits into the upper corner of the left edge 5B of the lens seat plate 5, and the wall groove 28C It fits into the upper corner of the right edge 5C of the lens seat plate 5. Therefore, when the cover 14 is closed, the interchangeable lens 1 is stored in the storage case 10 without play by the groove 24 on the case body 12 side and the groove 28 on the cover 14 side.
[0015]
According to the storage case 10 of the present embodiment configured as described above, the case main body, the lid 14, the hinge portion 16, and the grooves 24 and 28 are integrally formed, so that the case main body, the lid, and the like are configured separately. As compared with the conventional storage case, assembly is not required, and the manufacturing cost is reduced.
Further, since the storage case 10 of the present embodiment is integrally formed of an elastomer having high impact resistance, the interchangeable lens 1 can be protected from external impact.
[0016]
On the other hand, as shown in FIG. 1, in the storage case 10 of the present embodiment, bulges 30, 30 are formed at the upper short side edge of the lid 14, and concave grooves are formed on both sides of the bulges 30, 30. 32, 32 are respectively formed. Further, as shown in FIG. 4, convex legs 34, 34 that engage with the grooves 32, 32 are formed on the bottom of the case body 12. Therefore, in the storage case 10 of the present embodiment, as shown in FIG. 4, when the legs 34 of the case body 12 are engaged with the grooves 32 of the lid 14, the plurality of storage cases 10, 10. Since it can be stably stacked, it is convenient when carrying or storing a plurality of storage cases 10, 10.
[0017]
Further, as shown in FIG. 1, by attaching a label 36 on which the model number of the interchangeable lens 1 stored in the storage case 10 is printed on the upper surface of the cover 14, the model number of the interchangeable lens 1 can be changed without opening the cover. It can be confirmed from the outside of the storage case 10. The label 36 can be replaced according to the model number of the interchangeable lens 1 stored in the storage case 10.
[0018]
FIG. 5 is an explanatory view in which storage cases 10, 40, and 50 having different sizes are stacked and stored. The storage case 10 indicated by a two-dot chain line in the drawings is the storage case of the present embodiment shown in FIGS.
