Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[Form 1]
1 and 2 show an example of a power tool storage case (hereinafter simply referred to as “storage case”). This storage case 1 is made of a synthetic resin having a deep bottom rectangular box-shaped main body case 2 and a rectangular box-shaped shallow bottom body 3 similar to the main body case 2. A storage portion 4 is formed for storing a power tool body such as a rechargeable impact driver (not shown), a battery pack, a charger, and the like. The main body case 2 and the lid 3 have opening edges on the rear surface (the left side in FIG. 2 is the front) in a state where the upper opening of the main body case 2 and the lower opening of the lid 3 are combined. The shaft 5 is hinged to each other so as to be rotatable.

  On the other hand, the opening edges on the front side of the main body case 2 and the lid 3 can be locked / unlocked by a pair of left and right latches 6 and 6. The latch 6 is a so-called patch-on lock. Here, when the main body case 2 is opened, the upper end of the lever plate 7 is rotatably attached to a shaft, and a hook plate is provided at an intermediate portion of the lever plate 7. The lower end of 8 is rotatably attached to the shaft. Therefore, when the lever plate 7 is tilted downward along the front surface of the main body case 2 in a state where the upper end of the hook plate 8 is locked to a projection (not shown) provided when the lid 3 is opened, the lid 3 is The main body case 2 is locked in a closed state.

9 is a handle provided in the main body case 2 between the latches 6 and 6, and both ends of the handle 9 are rotatably connected to a pair of left and right lower projections 10 and 10 protruding forward from the latch 6 in the locked state. In a state where 9 is tilted to the front side of the main body case 2, the lower projections 10, 10 are prevented from protruding forward from the front surface. The lower protrusion 10 is provided with continuous vertical ridges 11 positioned outside the end of the tilted handle 9.
Further, a pair of left and right upper projections 12, 12 that are continuous with the lower projections 10, 10 of the main body case 2 with the lid 3 closed are provided on the front surface of the lid 3.

  A sub-accommodating portion 13 that accommodates small items such as a bit is recessed on the upper surface of the lid 3 in a state of being partitioned into a plurality of spaces. An outer lid 14 that opens and closes the upper surface is provided. The outer lid 14 is a square plate that covers the entire sub-accommodating portion 13, and a rear edge (not shown) bent downward is engaged with an engaging groove 13 a provided in the left-right direction along the rear edge of the sub-accommodating portion 13. By doing so, it is possible to rotate in the vertical direction around the rear edge. At the center of the front end of the outer lid 14, the lid 3 and the outer lid 14 are closed and project in a circular arc shape toward the front lower side to cover the front surface of the lid 3. A cover portion 15 as a continuous partitioning projection is provided in the left-right direction.

A square-shaped window 16 is formed in the center near the front of the outer lid 14, and a lock plate 17 serving as a lock portion is provided in the window 16. As shown in FIG. 3, the lock plate 17 is a square plate shape that fits into the window 16 and has an upper surface flush with the outer lid 14. A plate-like locking piece 19 provided with a forward barb 20 at the lower end is projected downward on the lower surface of 17 and in front of the finger hooking hole 18. The lower surface of the barb 20 is an inclined surface that becomes upward as it goes forward.
Further, a pair of side walls 21, 21 protrude downward from the lower surface of the lock plate 17 in front of the locking piece 19 and on the left and right sides, and shafts 22 that face each other on the left and right outer surfaces of the side walls 21. Is protruding. On the other hand, on the left and right inner surfaces of the window 16, receiving portions 23, 23 corresponding to the side walls 21 protrude downward, and shafts 22 are fitted into receiving holes 24 formed in the receiving portions 23. Thereby, the lock plate 17 is supported in the window 16 so as to be rotatable around the shaft 22.

  However, the front end of the lock plate 17 is a thin plate portion 25 that engages with the front edge of the window 16 from below, and the upper surface of the lock plate 17 is flush with the outer lid 14 in the clockwise rotation direction of FIG. The fitting position is not exceeded. In addition, an L-shaped spring receiving plate 26 located below the front end of the lock plate 17 extends from the lower surface of the outer lid 14 and in front of the lock plate 17, so that the spring receiving plate 26 and the front end of the lock plate 17 are extended. The coil spring 27 as an urging means is interposed in the vertical direction. As a result, the lock plate 17 is biased to the fitting position where the thin plate portion 25 abuts against the front edge of the window 16. Reference numeral 27 a denotes a guide rod that protrudes downward from the lower surface of the lock plate 17 directly behind the coil spring 27 to prevent the coil spring 27 from buckling.

  On the other hand, on the bottom surface of the sub-accommodating portion 13 of the lid 3, the locking plate 28 is parallel to the locking piece 19 at a position in front of the locking piece 19 of the lock plate 17 with the outer lid 14 closed. On the upper end of the locking plate 28, a locking projection 29 as a locked portion that locks the barb 20 of the locking piece 19 from below is projected backward. The upper surface of the locking projection 29 is an inclined surface that becomes downward as it goes rearward. That is, the inclination is the same as the barb 20 of the locking piece 19.

  In the storage case 1 configured as described above, when the outer lid 14 is opened in order to insert or remove small items in the sub-accommodating portion 13, a finger is inserted and hooked through the finger-engaging hole 18 of the lock plate 17, and the lock plate 17 Pull upward to raise. Then, the lock plate 17 rotates counterclockwise in FIG. 3 around the shaft 22 against the bias of the coil spring 27 and rotates the return 20 of the locking piece 19 in a direction away from the locking projection 29. In this way, the return 20 is in the unlocking position where it is released from the locking projection 29. Therefore, as shown in FIGS. 5 and 6, the sub-housing portion 13 can be opened by rotating the outer lid 14 upward about the rear end portion.

  On the other hand, when closing the outer lid 14, when the outer lid 14 is rotated to the closed side of the sub-accommodating portion 13, as shown in FIG. After the abutment, the return 20 gets over the locking projection 29 by the urging of the coil spring 27 and the guidance of the inclined surfaces as the outer lid 14 rotates. Then, when the outer lid 14 reaches the closed position, the lock plate 17 returns again as shown in FIGS. Therefore, the outer lid 14 is automatically locked as the sub storage portion 13 is closed.

  As described above, according to the storage case 1 of the first aspect, the outer lid 14 moves to the locking position to be locked with the locking projection 29 provided on the lid body 3 when the auxiliary storage portion 13 is closed. By providing the lock plate 17 that can be arbitrarily moved from the stop position to the lock release position for releasing the lock, the lock plate 17 is automatically locked when the sub-housing 13 is closed by the outer lid 14. When the outer lid 14 is opened, the lock is released only by pulling up the lock plate 17. Therefore, the outer lid 14 can be opened and closed with good operability, and it is easy to use.

In particular, since the coil spring 27 for urging the lock plate 17 to the engagement position with the engagement protrusion 29 is provided here, the automatic engagement with the lock plate 17 can be performed reliably.
Further, since the lock portion is the lock plate 17 provided separately from the outer lid 14, the lock portion can be obtained in an optimal form.
Furthermore, by providing the lock plate 17 so as to be flush with the outer surface of the outer lid 14, the possibility that the lock plate 17 is caught on the outside and accidentally unlocked is reduced.

In addition, the main body case 2 and the lid 3 are formed in a square box shape in which the back surfaces are hinged to each other and the front surfaces are arbitrarily locked / unlocked by the latches 6 and 6, and includes the auxiliary storage portion 13 and the lock plate 17. Since the outer lid 14 is provided on the upper surface of the lid body 3, the lifting of the lock plate 17 and the opening of the outer lid 14 are in substantially the same direction of operation, and therefore, from the lifting of the lock plate 17 to the opening of the outer lid 14. It can be performed continuously and smoothly.
Further, the handle 9 is provided in the left-right direction on the front side of the main body case 2 and the lid 3, and the cover portion 16 parallel to the handle 9 is provided on the outer lid 14 between the lock plate 17 and the handle 9. Thus, the handle 9 and the lock plate 17 are partitioned, and the possibility that the lock plate 17 is erroneously operated when the handle 9 is gripped is reduced.

[Form 2]
Next, another embodiment of the present invention will be described. However, since the other structure of the storage case is the same as that of the first embodiment except for the lock plate portion, the same components are denoted by the same reference numerals, description thereof is omitted, and the structure of the lock plate will be mainly described. .
In the storage case 1 a shown in FIG. 8, a notch 30 that becomes wider toward the front is formed in the center of the cover portion 15 at the front end of the outer lid 14, and a lock plate 31 is provided in the notch 30. ing. The lock plate 31 is a plate-like body whose front end curves downward in accordance with the cover portion 16, and as shown in FIG. 9, the shaft 33 protrudes from the left and right side walls 32, 32 provided substantially at the center in the front-rear direction. It is provided and is fitted in a receiving hole 35 of a receiving portion 34 provided on the inner surface of the notch 30. Here, since the thin plate portion 36 provided at the rear end of the lock plate 31 is engaged with the rear edge of the notch 30, the left rotation of the lock plate 31 is restricted.

Further, the locking piece 37 here is provided slightly forward of the shaft 33, and the barb 38 protrudes backward. On the other hand, the locking plate 39 stands up behind the locking piece 37, and the locking projection 40 protrudes forward. An inclined surface is formed on the lower surface of the barb 38 and the upper surface of the locking projection 40 as in the first embodiment.
The coil spring 41 is also provided between the spring receiving plate 42 extending to the outer lid 14 behind the notch 30 and the rear end of the lock plate 31 to urge the lock plate 31 in the counterclockwise direction. Yes. Reference numeral 43 is a guide rod, and 44 is a circular recess recessed in the upper surface of the lock plate 31 at a position rearward of the shaft 33.

  In the storage case 1a configured as described above, when the outer lid 14 is opened in order to put a small article in and out of the sub storage part 13, a finger is applied to the circular recess 44 of the lock plate 31 and pushed downward. Then, the lock plate 31 rotates rightward in FIG. 9 about the shaft 33 against the bias of the coil spring 41 and rotates the return 38 of the locking piece 37 in the direction away from the locking projection 40. As shown in FIG. 10, the return 38 moves to the unlocking position where it is released from the locking projection 40. Therefore, it is possible to open the sub-accommodating portion 13 by rotating the outer lid 14 upward about the rear end portion.

  On the other hand, when closing the outer lid 14, when the outer lid 14 is rotated to the closed side of the sub-accommodating portion 13, as shown in FIG. Then, as the outer lid 14 rotates, the return 38 gets over the locking projection 40 by the bias of the coil spring 41 and the guidance of the inclined surfaces. Then, when the outer lid 14 reaches the closed position, the lock plate 31 returns again to the locking position where the return 38 is locked to the locking protrusion 40 as shown in FIGS. Therefore, the outer lid 14 is automatically locked as the sub storage portion 13 is closed.

  Thus, also in the storage case 1a of the above-described form 2, the outer cover 14 moves to the locking position for locking the locking projection 40 provided on the lid 3 with the closing of the sub-storage portion 13, By providing the lock plate 31 that can be arbitrarily moved from the position to the lock release position for releasing the lock, the lock plate 31 can be automatically locked when the sub-storage portion 13 is closed by the outer lid 14. Thus, when the outer lid 14 is opened, the lock is released only by pulling up the lock plate 31. Therefore, the outer lid 14 can be opened and closed with good operability, and it is easy to use.

In particular, since the coil spring 41 that biases the lock plate 31 to the locking position to the locking projection 40 is provided, automatic locking by the lock plate 31 can be performed reliably.
Further, since the lock portion is the lock plate 31 provided separately from the outer lid 14, the lock portion can be obtained in an optimal form.
Furthermore, by providing the lock plate 31 so as to be flush with the outer surface of the outer lid 14, the possibility that the lock plate 31 is caught on the outside and accidentally unlocked is reduced.

In the first and second embodiments, the biasing means is not limited to the coil spring, and other elements such as a leaf spring and a resin spring may be appropriately employed. Also, the shaft and the receiving hole that rotatably support the lock plate are provided on the opposite sides, the inclined surface of the barb and the locking projection is provided on only one of them, or a curved surface is used instead of the inclined surface, etc. The design can be changed as appropriate.
Further, in the first and second embodiments, the lock plate is provided so as to be flush with the outer surface of the outer lid, but may be provided at a position recessed from the outer surface of the outer lid.
In the first and second embodiments, a separate lock plate is employed as the lock portion, but an elastic piece formed integrally with the outer lid can also be used as the lock portion.

  In addition, in the above embodiment, the lock plate itself is urged to the locking position by the urging means to enable automatic locking, but the urging means may not be used for the lock plate. For example, the outer lid is provided with a lock plate that can swing between the locking position and the locking release position, and the lid member is provided with a pressing member that contacts the lock plate and moves to the locking position when the outer lid is closed. If the projection is biased, the lock plate that contacts the pressing member moves to the locking position simultaneously with the closing of the outer lid, the outer lid is locked, and the locking plate is locked so that the pressing member is pushed in. When moving to the release position, the outer lid can be opened.

In addition, the shape of the outer lid may be a square or a trapezoid, and the pair of the sub-accommodating portion and the lid is not limited to one. For example, the sub-accommodating portion formed on the upper surface of the lid is a plurality of lids. The lock portion of the present invention can be applied to a device that opens and closes at the same time, or a device that is provided with a sub storage portion and a lid on the outer surface of the main body case.
Of course, the structure of the main body case and the lid is not limited to the above-mentioned form, and in addition to the overall shape, the shape, the number and arrangement of the latches and handles may be changed as appropriate.
