Japanese Patent Application Publication No. 2019-181694 Special Publication No. 7-73528

In the configuration of Patent Document 1, if the user lifts the power tool storage case without fixing the lid and the storage, there is a risk that the lid will open unexpectedly and the items stored in the storage will be scattered. .

In order to optimize the storage space, the height of the storage shelf for storing the power tool storage case as disclosed in Patent Document 1 is set to the minimum necessary height. Therefore, if the power tool storage case is stored in the storage shelf with the handle facing upward, the handle may not be accessible and it may be difficult to pull out the power tool storage case laterally from the storage shelf.

The configuration of Patent Document 2 makes it easy to pull out the trunk to the side without using the handle by using the handle on the side. However, since the handle was placed at the top of the side, it was difficult to operate when the trunk was placed on the upper shelf of the storage shelf. In addition, it was necessary to provide a pull storage recess on the side, which reduced the storage capacity of the trunk.

The present inventor recognized the following problems 1 to 3.
- Problem 1: To provide a power tool storage case that can prevent the lid from opening unexpectedly and scattering of items stored in the storage, regardless of the operation of fixing the lid to the storage.

(Embodiment 1)
1 to 26 relate to a power tool storage case 1 according to Embodiment 1 of the present invention. From FIG. 1, the front and rear, top and bottom, and left and right directions of the power tool storage case 1, which are perpendicular to each other, are defined.

The power tool storage case 1 includes a main case 10, a sub-case 20, a lid 30, a pair of side latches 40, a center latch 50, a handle 60, and a locking mechanism 70.

The main case 10 is an example of a storage section. The main case 10 is a box made of, for example, resin and has an open top, and can accommodate a power tool body, a battery pack, a charger, etc., respectively. As shown in FIG. 2, the main case 10 has a substantially rectangular bottom portion 11 and outer wall portions 12 rising from four sides of the bottom portion 11. Stacking convex portions 11a are provided near the four corners of the bottom surface portion 11, respectively. The main case 10 has a grounding portion 15 (convex portion) on the back surface. The ground portion 15 comes into contact with the mounting surface when the power tool storage case 1 is erected with the back side facing down.

The subcase 20 is an example of a storage section. The sub-case 20 is a box made of resin, for example, with an open top, and can store various small items inside. The sub case 20 is rotatably provided above the main case 10. The sub case 20 is rotatably connected to the main case 10 at the rear by a pair of first hinge parts 65 (first rotation support parts) shown in FIG. 2, and also functions as a lid for the main case 10.

The lid 30 is an example of a lid. The lid body 30 is made of resin, for example, and is rotatably provided above the sub-case 20. The lid body 30 is rotatably connected to the sub-case 20 at the rear by a pair of second hinge parts 67 (second rotation support parts) shown in FIG. 2, and functions as a lid for the sub-case 20.

The lid body 30 has a substantially rectangular upper surface portion 31 and outer wall portions 32 extending downward from four sides of the upper surface portion 31 . Stacking recesses 31a spaced apart from the edges of the upper surface portion 31 are provided near the four corners of the upper surface portion 31, respectively. When stacking a plurality of power tool storage cases 1, a stacking protrusion 11a provided on the bottom surface 11 of the main case 10 is fitted into a stacking recess 31a provided on the top surface 31 of the lid body 30.

The handle 60 is made of resin, has a U-shape, and is rotatably supported on the front surface of the main case 10 . A pair of handle base portions 16 are protruded from the front surface (outer wall portion 12 facing the front) of the main case 10 (provided to protrude forward), and both ends of the handle 60 are attached to the pair of handle base portions 16. Each is rotatably connected by a connecting pin (not shown).

The pair of side latches 40 are made of, for example, resin and have the same configuration, and are provided on both sides of the handle 60 to restrict the rotation of the sub case 20 relative to the main case 10 (the sub case 20 is attached to the main case 10). It is a fixing mechanism that locks the device against rotation. The side latch 40 includes a latch operation section 41 rotatably connected to the main case 10 and a latch body section 42 rotatably connected to the latch operation section 41 . The latch main body portion 42 engages with a locking portion (locking protrusion) (not shown) provided on the upper front surface of the sub-case 20 to restrict rotation of the sub-case 20 with respect to the main case 10 . The user can operate the latch operation section 41 to engage and disengage the latch body section 42 and the locking section.

The central latch 50 is made of resin, for example, and is a fixing mechanism that restricts rotation of the lid 30 relative to the subcase 20 (locks the lid 30 unrotatably relative to the subcase 20). The central latch 50 includes a latch operation section 51 rotatably connected to the subcase 20 and a latch main body section 52 rotatably connected to the latch operation section 51. The latch main body portion 52 engages with two locking portions 36 provided on the upper front surface of the lid body 30, and restricts rotation of the lid body 30 with respect to the sub-case 20. The user can operate the latch operation section 51 to engage and disengage the latch body section 52 and the locking section 36 .

The latch operation section 51 is formed in a U-shape, and allows the state of the locking mechanism 70, which will be described later, to be visually observed through the U-shaped gap. The latch main body portion 52 has a cutout portion 52a at the center in the left-right direction, and the operating portion 71 of the locking mechanism 70 faces outward from the cutout portion 52a.

The lid body 30 has a support convex portion 34 at a position behind the latch body portion 52 of the central latch 50 in the rotation restriction enabled state. The support protrusion 34 is provided at the center of the front surface of the lid 30. Note that the two aforementioned locking portions 36 of the lid body 30 are provided on both left and right shoulder portions of the support convex portion 34, respectively. The support protrusion 34 supports the locking mechanism 70.

(Simple locking mechanism)
Hereinafter, a simple locking mechanism in the power tool storage case 1 will be explained.

The locking mechanism 70 is a simple locking mechanism for the lid body 30. The locking mechanism 70 is a process in which the lid body 30 changes from a state in which the opening 20a (hereinafter referred to as "subcase opening") of the subcase 20 shown in FIGS. 19 and 20 is opened to a state in which it covers the subcase opening. The lid 30 becomes locked due to its own weight, and in the locked state, the lid 30 is prevented from changing from covering the sub-case opening to opening the sub-case opening.

The locking mechanism 70 includes an operating section 71, an arm base 72, an arm 73, a locked section 74, a roller 75 as a locking section, and a leaf spring 78 as a biasing means.

The operation unit 71 is operated by the user when releasing the locked state by the locking mechanism 70. Arm base 72 supports arm 73. The operating portion 71 and the arm base 72 are, for example, an integral resin molded body, and are rotatably supported by the support convex portion 34 about a rotation axis parallel to the left-right direction. The arm 73 is made of metal, for example, and extends downward from the arm base 72 in a U-shape, and is rotatable together with the arm base 72 about a rotation axis parallel to the left-right direction. The roller 75 is supported by the lower part of the arm 73 and is rotatable with respect to the arm 73 about a rotation axis parallel to the left-right direction. The leaf spring 78 biases the operating portion 71 in a direction (counterclockwise direction in FIG. 11A) toward the supporting convex portion 34 so that the operating portion 71 is in the locked state.

The locked portion 74 is a convex portion provided at the front portion of the sub-case 20. The locked portion 74 is preferably a resin molded body integral with the subcase 20. The locked portion 74 has an inclined portion 76 on its upper surface and a barbed portion 77 on its lower surface. As shown in FIGS. 23(A) and 26(A), the inclined portion 76 is formed by the roller 75 during the process in which the lid body 30 changes from the state where the sub-case opening is opened to the state where the sub-case opening is covered. This is the part to overcome. As shown in FIGS. 11(A) and 14(A), the barb portion 77 prevents the roller 75 from moving when the lid body 30 attempts to move toward the open state of the sub-case opening in the locked state. This is the part that gets stuck.

9 to 26 show the opening and closing operations of the lid body 30.

9 to 11 show a state in which the lid 30 is closed and fixed to the sub-case 20 by the central latch 50. FIGS. In the states shown in FIGS. 9 to 11, the lid body 30 covers the sub-case opening. In the states shown in FIGS. 9 to 11, there is a gap of a predetermined length in the vertical direction between the barbed portion 77 of the locked portion 74 and the roller 75. Therefore, if the lid body 30 is not fixed by the central latch 50, the lid body 30 can be rotated upward relative to the sub-case 20 by this gap (FIGS. 12 to 14). That is, the locking mechanism 70 allows the lid 30 to be opened by a predetermined length from the position where it can be fixed by the central latch 50 (the state shown in FIGS. 9 to 11).

12 to 14 show a state in which the lid body 30 is stopped by the locking mechanism 70 when it attempts to open in a state in which the fixation by the central latch 50 is released. Even if the user forgets to fix the lid using the central latch 50, the locking mechanism 70, specifically the roller 75 hitting and catching the barb 77, will cause the lid to move beyond the state shown in FIGS. 12 to 14. 30 is restrained from opening. The states shown in FIGS. 12 to 14 are also states in which the lid body 30 covers the sub-case opening.

15 to 17 show states in the middle of opening the lid body 30 after releasing the locking by the locking mechanism 70. The user can release the locking by the locking mechanism 70 by rotating the operating part 71 in the clockwise direction of FIG. By rotating it upward, the lid 30 can be opened (the sub-case opening is left open) as shown in FIGS. 18 to 20. The states shown in FIGS. 18 to 20 are states in which the lid body 30 opens the sub-case opening.

21 to 23 show states in which the roller 75 comes into contact with the inclined portion 76 of the locked portion 74 during the process of closing the lid 30 from the state shown in FIGS. 18 to 20. From this state, due to the weight of the lid 30, the roller 75 rotates and climbs over the slope 76 as shown in FIGS. 24 to 26. The biasing force of the leaf spring 78 is made small enough to allow the roller 75 to get over the inclined portion 76. Although not shown, the lid 30 further rotates downward due to its own weight from the state shown in FIGS. 24 to 26 until it reaches the same position as shown in FIGS. 9 to 11. After the roller 75 gets over the slope 76, it returns to the state shown in FIGS. 9 to 11 due to its own weight and the bias of the leaf spring 78.

As another configuration example of the locking mechanism 70, the locked portion 74 may be a locked portion 74A provided at the front portion of the main case 10, as shown in FIG. In this case, it is also possible to easily lock the lid portion 30 to the main case 10.

(Configuration related to drawing out from storage shelf)
Hereinafter, a configuration for pulling out the power tool storage case 1 from a storage shelf 90 as shown in FIG. 8 will be described.

The upper surface part 31 of the lid part 30 forms the upper surface part of the power tool storage case 1. The bottom surface portion 11 of the main case 10 constitutes a lower surface portion (hereinafter referred to as "case lower surface portion") of the power tool storage case 1. The outer wall portion 12 of the main case 10, the outer wall portion 22 of the sub case 20, and the outer wall portion 32 of the lid portion 30 are a pair of side portions (hereinafter referred to as “case side portions”) and a front portion (hereinafter referred to as “case side portions”) of the power tool storage case 1. (hereinafter referred to as the "case back part"). As shown in FIG. 8, the power tool storage case 1 can be stored in the storage shelf 90 with the front side of the case facing upward (hereinafter referred to as the "upright position").

The lid portion 30 has two recesses 33. The two recesses 33 are provided at the front left end and the front right end of the lid 30 so as to span over the top and front surfaces of the lid 30, respectively. As shown in FIG. 4, ribs 35 and 39 are provided on the lid 30 as the left and right walls of the recess 33. As shown in FIG.

The right rib 35 forms a right wall portion of the right recess 33. The left rib 35 forms the left wall of the left recess 33. The rib 35 is an example of a first operating section, and is an operating section for laterally drawing out the power tool storage case 1 stored in the storage shelf 90 in an upright position. The rib 35 is located above the vertical center of the power tool storage case 1 in the upright position.

As shown in FIG. 4, the front end of the rib 35 is located behind the front end of the power tool storage case 1 by a length L1. The front end of the power tool storage case 1 is, for example, the front end of the side latch 40 or the front end of the center latch 50.

The right rib 39 forms the left wall of the right recess 33. The left rib 39 forms the right wall of the left recess 33. The rib 39 is located between the recess 33 and the side latch 40 in the left-right direction. The ribs 39 make it difficult for a finger to touch the side latch 40 when inserting a finger into the recess 33.

The lid part 30 has two recesses 37. The two recesses 37 are provided at the rear left end portion and the rear right end portion of the lid portion 30, spanning the upper surface and the back surface of the lid portion 30, respectively. As shown in FIG. 4, two ribs 38 are provided on the lid 30 as a right wall of the right recess 37 and a left wall of the left recess 37.

The rib 38 is an example of a second operating section, and is an operating section for laterally drawing out the power tool storage case 1 stored in the storage shelf 90 in an upright position. The rib 38 is located below the vertical center of the power tool storage case 1 in the upright position.

As shown in FIG. 4, the rear end portion of the rib 38 is located behind the rear end portion of the power tool storage case 1 by a length L2. The rear end portion of the power tool storage case 1 is, for example, the rear end portion of the grounding portion 15.

Main case 10 has two ribs 13. The two ribs 13 protrude forward at both left and right ends of the front surface of the main case 10 and extend in the vertical direction. The rib 13 is formed by cutting out the lower part of the rib that was provided along the entire length of the main case 10 in the vertical direction to protect the side latch 40. (does not reach the lower end of the main case 10). Alternatively, the rib 13 extends to the lower end of the main case 10, but its forward protrusion length is longer at the upper portion and shorter at the lower portion.

The rib 13 is an example of a first operating section, and is an operating section for laterally drawing out the power tool storage case 1 stored in the storage shelf 90 in an upright position. The rib 13 is located above the vertical center of the power tool storage case 1 in the upright position.

Main case 10 has two ribs 14. The two ribs 14 protrude rearward from both left and right ends of the back surface of the main case 10 and extend in the vertical direction. The rib 14 is a reinforcing rib of the first hinge part 65 extended downward, and is provided in a range from the first hinge part 65 located at the upper end of the main case 10 to the middle part in the vertical direction. (It does not reach the lower end of the main case 10). The rib 14 extends to the lower end of the main case 10, but may have a configuration in which the length of the rib 14 protrudes rearward is longer at the upper part and shorter at the lower part.

The rib 14 is an example of a second operating section, and is an operating section for laterally pulling out the power tool storage case 1 stored in the storage shelf 90 in an upright position. The rib 14 is located below the vertical center of the power tool storage case 1 in the upright position.

When a large number of power tool storage cases 1 are stored in the storage shelf 90 in an upright position as shown in FIG. It can be easily pulled out from the storage shelf 90 to the side (towards the front in the paper of FIG. 8).

According to this embodiment, the following effects can be achieved.

(1) The locking mechanism 70 becomes locked due to the weight of the lid 30 during the process from the state in which the sub-case opening is opened to the state in which it covers the sub-case opening, and in the locked state. The lid body 30 is prevented from changing from a state in which the subcase opening is covered to a state in which the subcase opening is opened. Therefore, even if the user forgets to fix the lid part 30 to the sub-case 20 using the central latch 50, it is possible to prevent the lid part 30 from opening unexpectedly and scattering the items stored in the sub-case 20.

(2) The locking by the locking mechanism 70 can be released with a single action of rotating the operating section 71 upward, making it easy to use.

(3) Since the leaf spring 78 urges the operation part 71 in the direction of locking, the roller 75 that has climbed over the slope part 76 is moved to the locking effective position (rotational position of the roller 75 shown in FIG. 11(A)). ), that is, the certainty that the locking by the locking mechanism 70 will be effective when the lid portion 30 is closed is increased. On the other hand, since the biasing force of the leaf spring 78 is small enough to allow the roller 75 to get over the inclined part 76, the roller 75 cannot get over the inclined part 76 and the lid part 30 cannot be closed due to its own weight. Risks are contained.

(4) In the locking mechanism 70, the engaging portion that engages with the locked portion 74 is the roller 75. Since the roller 75 can roll over the sloped part 76, it is possible to suppress the risk that the lid part 30 will not be able to close due to its own weight due to the roller 75 not being able to roll over the sloped part 76 and stopping.

(5) The locked portion 74 has an inclined portion 76 on the upper surface that the roller 75 rides over when the lid portion 30 is closed. Therefore, compared to the case where the upper surface of the locked part 74 is, for example, a plane perpendicular to the up-down direction, it becomes easier for the roller 75 to climb over the locked part 74 downward, and the lid part 30 will not close due to its own weight alone. Risk can be controlled.

(6) The locked portion 74 has a barb portion 77 on the lower surface on which the roller 75 is caught when the lid body 30 attempts to move toward the state in which the sub-case opening is opened in the locked state. For this reason, compared to the case where the lower surface of the locked part 74 is a plane perpendicular to the up-down direction, the roller 75 can unexpectedly climb over the locked part 74 upwards, that is, the locking mechanism 70 can can reduce the risk of being canceled unexpectedly.

(7) The latch operation part 51 is formed in a U-shape, and the user can visually check the state of the locking mechanism 70 through the U-shaped gap, making it easy to use.

(8) In the states shown in FIGS. 9 to 11, there is a gap of a predetermined length in the vertical direction between the barbed portion 77 of the locked portion 74 and the roller 75. That is, the locking mechanism 70 allows the lid 30 to be opened by a predetermined length from the position where it can be fixed by the central latch 50 (the state shown in FIGS. 9 to 11) (FIGS. 12 to 14). Therefore, even if there are too many items stored in the sub-case 20 and the lid part 30 cannot be completely closed, the locking by the locking mechanism 70 can be made effective, and it is easy to use. Furthermore, the gap of a predetermined length between the barb portion 77 and the roller 75 in the states shown in FIGS. The benefits of locking are enhanced. If there were no gap, the locking by the locking mechanism 70 would not become effective unless the lid portion 30 was completely closed, but this embodiment does not have such a problem.

(9) The power tool storage case 1 has ribs 13, 14, 35, and 38 as operation parts for laterally pulling out the power tool storage case 1 stored in the storage shelf 90 in an upright position. Therefore, by hooking a finger on at least one of the ribs 13, 14, 35, and 38, the power tool storage case 1 can be easily pulled out from the storage shelf 90 to the side (towards the front in the paper of FIG. 8), which improves usability. good. Note that the ribs 13, 14, 35, and 38 are operating parts that can be hooked with fingers from the sides, so they can also be used to pull out the power tool storage case 1 stored in the storage shelf in a posture other than the standing posture. Available for use.

(10) Since the ribs 13 and 35 are located above the vertical center of the power tool storage case 1 in the upright position, they are preferably used to pull out the power tool storage case 1 stored in the lower stage of the storage shelf 90. can. Since the ribs 14 and 38 are located below the vertical center of the power tool storage case 1 in the upright position, they can be suitably used to pull out the power tool storage case 1 stored in the upper stage of the storage shelf 90. That is, the power tool storage case 1 is easy to pull out laterally from the storage shelf 90 regardless of whether it is placed on the upper or lower level of the storage shelf 90, and is convenient to use.

(11) The rib 13 is a rib that was provided along the entire length of the main case 10 in the vertical direction in order to protect the side latch 40, and the lower part of the rib is cut out, reducing the storage capacity of the main case 10. I won't let you. Further, the rib 14 is a reinforcing rib of the first hinge portion 65 extended downward, and does not reduce the storage capacity of the main case 10. In addition, the recesses 33 and 37 for forming the ribs 35 and 38 are provided at the four corners of the lid 30 and can be made to the minimum size that allows fingers to be inserted, so that the sub case 20 can be stored. Capacity reduction can be suppressed. In other words, the power tool storage case 1 has a structure that allows it to be easily pulled out laterally from the storage shelf 90, yet it is possible to suppress a decrease in the storage capacity.

(12) Since the recesses 33 and 37 for forming the ribs 35 and 38 are provided at the four corners of the lid 30, it is difficult to provide a waterproof structure by providing packing between the lid 30 and the sub-case 20. Less likely to get in the way.

(13) Since each of the ribs 13, 14, 35, and 38 is provided on both the left and right sides of the power tool storage case 1, the ribs 13, 14, 35, and 38 are provided on both the left and right sides of the power tool storage case 1 stored in the storage shelf 90. Regardless of which side is on the front side, the power tool storage case 1 can be easily pulled out laterally from the storage shelf 90, making it convenient to use.

As a modification of this embodiment, any one of the ribs 13, 14, 35, and 38 may be omitted. Although it is convenient to have four types of ribs as a drawer operation part, a certain level of convenience can be ensured even if only the combination of ribs 35 and 38 or only the ribs 13 and 14 is used, for example. Alternatively, even if only one type of ribs 13, 14, 35, and 38 is used, it is possible to obtain a structure in which it is easy to pull out sideways from the storage shelf 90, while suppressing a decrease in the storage capacity.

(Embodiment 2)
28 to 30 relate to the power tool storage case 2 according to the second embodiment of the present invention. The power tool storage case 2 is different from the power tool storage case 1 of Embodiment 1 in the configuration related to the drawer from the storage shelf 90. The differences will be mainly explained below.

The power tool storage case 2 has a lid portion 130. The lid 130 is a member corresponding to the lid 30. The lid portion 130 has low back portions 131 at both left and right ends, and has ribs 132 on the low back portions 131. The low back portion 131 is a portion where the top surface of the lid portion 130 is lowered one step. A groove for inserting a finger is formed between the side wall portion of the low back portion 131 and the rib 132. The ribs 132 are provided in a range excluding the front end and rear end of the low back portion 131. Therefore, the power tool storage case 2 can be pulled out from the storage shelf 90 by hooking a finger on the back side of the rib 132 from above or below the rib 132.

In this embodiment, although the storable capacity is reduced by the amount of the low-back portion 131, the effect of making it easier to pull out the items laterally from the storage shelf 90 can be obtained.

(Embodiment 3)
FIG. 31(A) is a front view of the right half of the power tool storage case 3 according to Embodiment 3 of the present invention. FIG. 31(B) is an enlarged view of section P in FIG. 31(A). FIG. 31(C) is a perspective view of the main parts of the power tool storage case 3. In the power tool storage case 3, the ribs 132 of the second embodiment are replaced with ribs 232. The rib 232 has a curved portion 233 at its upper end, making it easy to catch a finger thereon.

(Embodiment 4)
FIG. 32(A) is a side view of the power tool storage case 4 according to Embodiment 4 of the present invention. FIG. 32(B) is a perspective view of the main parts of the power tool storage case 4. In the power tool storage case 4, the ribs 132 of the second embodiment are replaced with ribs 332. The ribs 332 are provided separately at the front and rear of the low back portion 131, and are not present in the middle portion of the low back portion 131 in the front-rear direction. Therefore, hook your finger on the back side of the lower rib 332 from above the lower rib 332 or hook your finger on the back side of the upper rib 332 from below the upper rib 332 to open the power tool storage case 4. It can be pulled out from the storage shelf 90.
