Description

[Technical Field]

[0001] The present disclosure relates to a small case for a power tool for storing accessories of a power tool such as a screwdriver. [Background technology]

[0002] Dedicated cases have been provided in the past for storing and carrying power tools such as screwdrivers and small items for power tools. Various technologies relating to this type of case have been disclosed in the following patent documents. For example, the case disclosed in Patent Document 1 has a rectangular box-shaped housing that is open at the top, and a cover that is connected to the housing so that the opening of the housing can be opened and closed. When the opening of the housing is closed, the cover can be secured to the housing by a latch (lock). The cover can be locked in the closed position by operating the latch to the closing side. The cover can be opened by operating the latch to the opening side.

[0003] Accessory cases for power tools can accommodate a variety of small items, including, for example, fasteners such as screws and anchor bolts, accessories such as cutting tools and batteries, small tools such as tape measures, and small power tools. Therefore, there is a demand for a system that allows easy viewing of the interior of the accessory case even when the cover is closed. For example, by increasing the light transmittance of the cover, the interior of the accessory case can be clearly seen from the outside. It is desirable for a highly light-transmitting cover not to have features that impede visibility, such as a handle. Therefore, it is difficult to achieve both visibility of the interior of the accessory case and ease of carrying the accessory case, leaving room for improvement. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2017-039194 Summary of the Invention [Problem to be solved by the invention]

[0005] Therefore, there is a need for a small case for a power tool that allows good visibility inside the case when the cover is closed and is easy to carry. [Means for solving the problem]

[0006] According to one aspect of the present disclosure, a power tool case includes a box-shaped housing with an opening at the top. The power tool case includes a cover that is rotatably connected to the rear wall of the housing to open and close the opening and is made of a light-transmitting material. The power tool case includes a locking mechanism that secures the cover to the housing. The power tool case includes a right grip portion that is provided on the right wall of the housing. The power tool case includes a left grip portion that is provided on the left wall of the housing. The power tool case includes a plurality of small boxes that are removably accommodated in the housing.

[0007] Therefore, by providing a cover made of a light-transmitting material, the inside of the housing can be easily seen when the cover is closed. This makes it easy to see the multiple small boxes housed in the housing and the small items housed in the small boxes. Moreover, by holding the right and left grips with both hands, the user can carry the small power tool case with the cover facing up. This allows the user to carry and place the small power tool case in a position that makes it easy to see the inside of the housing through the cover. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] According to another feature of the present disclosure, the power tool case has a handle rotatably connected to the front wall of the housing, so that a user can easily carry the power tool case by grasping the handle with the front wall of the housing facing upward.

[0010] According to another feature of the present disclosure, the right grip portion is rotatably connected to the right wall. The left grip portion is rotatably connected to the left wall. Therefore, when transporting the power tool case, the right grip portion is rotated to a use position protruding from the right wall, and the left grip portion is rotated to a use position protruding from the left wall. This allows the right grip portion and the left grip portion to be positioned in a way that makes them easier for the user to grasp. When placing or storing the power tool case, the right grip portion is rotated to a storage position conforming to the right wall, and the left grip portion is rotated to a storage position conforming to the left wall. This allows the right grip portion and the left grip portion to be stored compactly. This improves the convenience of the power tool case.

[0011] According to another feature of the present disclosure, the rotation fulcrum of the right grip portion is provided at the upper part of the right grip portion. The rotation fulcrum of the left grip portion is provided at the upper part of the left grip portion. Therefore, when the right grip portion and the left grip portion are rotated to the use position, the lower part of the right grip portion protrudes rightward beyond the right wall, and the lower part of the left grip portion protrudes leftward beyond the left wall. Because the upper parts of the right grip portion and the left grip portion are close to the rotation fulcrum, protrusion into the housing in the use position is suppressed. Therefore, loss of housing volume due to the provision of the right grip portion and the left grip portion can be suppressed.

[0012] According to another feature of the present disclosure, the cover has an inner holder that holds a nameplate inside the cover. The nameplate is visible through the cover. Therefore, the nameplate can be held adjacent to a small item housed in, for example, a small power tool case. This allows the small item and the nameplate to be easily associated and identified. Furthermore, by using a cover with high light transmittance, the nameplate can be easily seen from the outside of the cover.

[0013] According to another feature of the present disclosure, the housing has an outer holder for holding a nameplate, thereby making efficient use of wall space of the housing so that a nameplate for identifying a small item can be attached.

[0014] According to another feature of the present disclosure, the locking mechanism includes a latch movably mounted on the housing so as to connect another power tool case to the lower portion of the housing. Therefore, the latch can be used to connect another power tool case to the lower portion of the housing of the small power tool case. The connected small power tool case and the other power tool case can be carried together by grasping the right and left grips.

[0015] According to another feature of the present disclosure, the cover has a main plate with a first light transmittance that allows the small box to be viewed. The cover has a frame portion that protrudes upward from the outer periphery of the main plate and has a second light transmittance that is lower than the first light transmittance. Therefore, the main plate is formed in a recess that is lower in height than the frame portion. Therefore, other power tool cases can be stacked above the frame portion without contacting the main plate. This allows the main plate to maintain its high light transmittance.

[0016] Next, one embodiment of the present disclosure will be described with reference to FIGS. 1 to 29. A power tool accessory case 1 can accommodate a variety of small items, including fasteners such as screws and anchor bolts, accessories such as tool inserts and batteries, small tools such as tape measures, and small power tools. As shown in FIG. 1, the power tool accessory case 1 includes a rectangular box-shaped housing 2 with an opening 2a at its top and a cover 3 connected to the housing 2 so as to open and close the opening 2a. The cover 3 rotates vertically relative to the housing 2 about a hinge shaft 4 at its rear as a rotation center to open and close the cover 3. When closed, the cover 3 covers the entire opening 2a from above. In the following description, the up-down, front-rear directions are defined with the side with the opening 2a defined as the top and the side with the hinge shaft 4 defined as the rear. The left-right directions are defined from the perspective of a user positioned in front of the power tool accessory case 1 (nearby).

One of the pair of rotation support shafts 15b extends rearward from the front surface of the storage recess 15a, and the other extends forward from the rear surface of the storage recess 15a, and they are provided coaxially. The right surface of the storage recess 15a includes an upper wall surface 15c and a lower wall surface 15d. The upper wall surface 15c extends substantially vertically in a flat shape from the top end of the storage recess 15a to near the bottom end of the rotation support shaft 15b. The lower wall surface 15d extends substantially vertically in a flat shape from the bottom end of the storage recess 15a to approximately half its height. The lower wall surface 15d is located slightly to the left (inner) of the upper wall surface 15c. The lower end of the upper wall surface 15c and the upper end of the lower wall surface 15d are connected by a gently sloping surface.

[0041] As shown in FIG. 16, the storage recess 17a of the left wall 17 is provided as a substantially rectangular recess with its left and bottom ends open below the inch scale 17h. The storage recess 17a is provided bilaterally symmetrically with the storage recess 15a (see FIG. 15). That is, a pair of rotation support shafts 17b that protrude in the front-rear direction and extend coaxially in a cylindrical shape are provided on the front and rear surfaces of the upper part of the storage recess 17a. The right surface of the storage recess 17a includes an upper wall surface 17c and a lower wall surface 17d that each extend substantially vertically in a flat shape. The upper wall surface 17c extends from the upper end of the storage recess 17a to near the lower end of the rotation support shafts 17b. The lower wall surface 17d extends slightly to the right (inner) of the upper wall surface 17c to approximately half the height from the bottom end of the storage recess 17a. The lower end of the upper wall surface 17c and the upper end of the lower wall surface 17d are connected by a gently sloping surface.

[0042] As shown in Figures 13, 14, and 19, the right grip 6 has a longitudinal direction in the front-rear direction and is also relatively long in the up-down direction. A cylindrical portion 6b having a through-hole penetrating therethrough in the front-rear direction and extending in the front-rear direction is provided at the top of the right grip 6. The central axis of the cylindrical portion 6b extends in the front-rear direction and corresponds to the rotation fulcrum 6a of the right grip 6. The front and rear ends of the through-hole of the cylindrical portion 6b are connected to a pair of rotation support shafts 15b (see Figure 15). This allows the right grip 6 to rotate around the rotation fulcrum 6a.

[0043] As shown in Figures 13, 14, and 19, a flat anti-rotation wall 6c is provided above the cylindrical portion 6b. The anti-rotation wall 6c extends upward as it moves to the right in the storage position. The anti-rotation wall 6c forms an inclination angle of 30° to 40°, for example, 35°, with respect to the right end face of the right wall 15 in the storage position. The anti-rotation wall 6c abuts against the upper wall surface 15c in the use position to prevent rotation of the right grip 6. The right grip 6 extends downward as it moves to the right in the use position and is inclined at a predetermined angle, for example, 35°, with respect to the right end face of the right wall 15. Approximately half of the lower portion of the right grip 6 protrudes rightward from the right end face of the right wall 15 in the use position.

[0044] As shown in Figures 13, 14, and 19, the right grip 6 has an inner wall end 6d below the anti-rotation wall 6c and to the left of the cylindrical portion 6b in the storage position. The inner wall end 6d is provided at both the front and rear ends of the right grip 6. The pair of inner wall end 6d abuts against the upper wall surface 15c in the storage position. An inner wall 6e is provided between the pair of inner wall end 6d, slightly recessed to the right of the inner wall end 6d. In the storage position, the inner wall 6e is approximately parallel to the upper wall surface 15c and forms a gap between the upper wall surface 15c and the lower wall surface 15d. In particular, the user's fingers can easily enter the gap between the inner wall 6e and the lower wall surface 15d. By inserting a finger into the gap and pulling the inner wall 6e upward and to the right, the right grip 6 can be rotated from the storage position to the use position. The inner wall 6e is provided with ribs that extend in the front-rear direction and slightly protrude from the inner wall 6e to prevent slipping when the user grips it.

[0045] 13, 14, and 19, the right grip 6 has a flat outer wall 6f to the right of the cylindrical portion 6b. In the storage position, the outer wall 6f is stored in the storage recess 15a so as not to protrude beyond the right end face of the right wall 15, and extends vertically along the right end face of the right wall 15. The lower end of the outer wall 6f is connected to the lower end of the inner wall end 6d and the lower end of the inner wall 6e via arc-shaped curved surfaces.

[0046] As shown in Figures 13, 14, and 19, the left grip 7 is provided symmetrically with the right grip 6. That is, a cylindrical portion 7b and a rotation-preventing wall portion 7c are provided at the upper portion of the left grip 7. The cylindrical portion 7b has a through-hole that penetrates in the front-rear direction and extends in the front-rear direction. The central axis of the cylindrical portion 7b corresponds to the rotation fulcrum 7a of the left grip 7. The front and rear ends of the through-hole in the cylindrical portion 7b are connected to a pair of rotation support shafts 17b (see Figure 16). The rotation-preventing wall portion 7c is located above the cylindrical portion 7b in the storage position and extends upward toward the left. In the storage position, the rotation-preventing wall portion 7c is inclined at an angle of 30° to 40°, for example, 35°, relative to the left end face of the left wall 17. In the use position, the rotation-preventing wall portion 7c abuts against the upper wall surface 17c to prevent rotation of the left grip 7. In the use position, the left grip portion 7 extends downward as it moves leftward and is inclined at an angle of, for example, 35° with respect to the left end face of the left wall 17. Approximately the lower half of the left grip portion 7 protrudes leftward from the left end face of the left wall 17 in the use position.

[0047] As shown in Figures 13, 14, and 19, in the storage position, the left grip 7 has inner wall end portions 7d and an inner wall 7e below the anti-rotation wall portion 7c and to the left of the cylindrical portion 7b. The inner wall end portions 7d are provided at both the front and rear ends of the left grip 7. The inner wall 7e is slightly recessed to the left between the pair of inner wall end portions 7d. The pair of inner wall end portions 7d abut against the upper wall surface 17c in the storage position. In the storage position, the inner wall 7e is approximately parallel to the upper wall surface 17c and forms a gap between the lower wall surface 17d and the inner wall 7e, allowing a user's fingers to easily insert. By inserting a finger into the gap and pulling the inner wall 7e upward and to the left, the left grip 7 can be rotated from the storage position to the use position. The inner wall 7e has a rib that extends forward and backward and slightly protrudes from the inner wall 7e to prevent slippage when the user grips the device.

[0048] 13, 14, and 19, the left grip 7 has a flat outer wall 7f to the left of the cylindrical portion 7b. In the storage position, the outer wall 7f is stored in the storage recess 17a so as not to protrude beyond the left end face of the left wall 17, and extends vertically along the left end face of the left wall 17. The lower end of the outer wall 7f is connected to the lower end of the inner wall end 7d and the lower end of the inner wall 7e via arc-shaped curved surfaces.

[0049] As shown in Figure 9, another power tool case 40 can be connected to the lower part of the power tool accessory case 1. The power tool case 40 has a rectangular box-shaped housing 41 with an opening at the top, and a cover 42 connected to the housing 41 via a hinge shaft 43 so that the opening can be opened and closed. The housing 41 is provided with a total of four latches 44: two on the front wall, one on the right wall, and one on the left wall. The cover 42 is secured in a closed state to the housing 41 by the two latches 44 on the front wall. The power tool case 40 accommodates a power tool such as a screwdriver, as well as accessories such as a tool tip and a battery.

[0050] As shown in Figure 9, the four legs 11a (see Figures 3 to 5) of the housing 2 are placed on the four recesses provided on the top surface of the cover 42. The four latches 44 are connected to the connecting protrusions 13f of the locking mechanism 13, the connecting protrusions 14f of the locking mechanism 14, the connecting protrusions 16f of the locking mechanism 16 (see Figure 10), and the connecting protrusions 18f of the locking mechanism 18 (see Figure 1). As a result, the housing 2 of the small power tool case 1 is connected integrally in the vertical direction with the housing 41 and cover 42 of the power tool case 40.

[0051] Another power tool case 1 can be connected below the power tool case 1 shown in FIG. 9 . A power tool case 40 or another power tool case 1 can be placed on top of the power tool case 1 for connection. The legs of the power tool case 40 or another power tool case 1 are placed in the four rectangular recesses 23a of the cover 3. The latches 13a, 14a, 16a, and 18a are connected to the connecting protrusions provided on the bottom of the power tool case 40 or another power tool case 1. This vertically connects the housing 2 and cover 3 of the power tool case 1 to the housing 41 of the power tool case 40 or the housing 2 of the power tool case 1. Because the main plate 22 is located below the rectangular recesses 23a, contact with the power tool case 40 or another power tool case 1 placed above is suppressed.

[0052] As shown in FIG. 12 , with the power tool case 1 connected to the top of the power tool case 40, the right grip 6 and the left grip 7 can be rotated between the storage position and the use position. A user can carry the power tool case 1 and the power tool case 40 together by holding the right grip 6 and the left grip 7 with both hands when they are in the use position. Another power tool case 40 or another power tool case 1 can be connected to the bottom of the power tool case 40. By using the right grip 6 and the left grip 7, a user can carry one or more power tool case 1 and multiple power tool cases 40 together.

[0053] As shown in FIG. 4 , an outer holder 15e capable of holding a nameplate 37 is provided on the right wall 15 in front of the right grip portion 6. The outer holder 15e is slightly concave toward the left with respect to the right end face of the right wall 15. Therefore, the lower end of the outer holder 15e has a step between the right end face of the right wall 15 and the lower end of the outer holder 15e that can support the lower end of the nameplate 37. The outer holder 15e has a pair of insertion ribs 15f and a pair of retaining ribs 15g. The pair of insertion ribs 15f are provided on both left and right ends of the outer holder 15e. The pair of insertion ribs 15f protrude in the front-rear direction from both left and right ends of the outer holder 15e toward the center and extend in the up-down direction. The pair of retaining ribs 15g are arranged side by side in the front-rear direction at the upper end of the outer holder 15e. The retaining ribs 15g protrude to the right and extend in the front-rear direction.

[0054] 4 can be inscribed with, for example, the name of an item to be stored in the power tool accessory case 1. The nameplate 37 is held in the outer holder 15e by a step at the bottom end of the outer holder 15e, a pair of insertion ribs 15f, and a pair of retaining ribs 15g. The outer holder 15e can hold, together with the nameplate 37, a light-transmitting plate cover that covers the display surface of the nameplate 37 and allows the display surface to be clearly visible.

[0055] As shown in FIG. 5, an outer holder 17e capable of holding a nameplate 37 is provided on the left wall 17 in front of the left grip portion 7. The outer holder 17e is provided in the same manner as the outer holder 15e (see FIG. 4). That is, a step capable of supporting the lower end of the nameplate 37 is provided at the lower end of the outer holder 17e. The outer holder 17e has a pair of insertion ribs 17f extending in the vertical direction at both left and right ends of the outer holder 17e, and a pair of retaining ribs 17g extending side by side in the front-rear direction at the upper end of the outer holder 17e. The nameplate 37 is held in the outer holder 17e by the step at the lower end of the outer holder 17e, the pair of insertion ribs 17f, and the pair of retaining ribs 17g. The outer holder 17e can hold, together with the nameplate 37, a light-transmitting plate cover that covers the display surface of the nameplate 37 and allows the display surface to be clearly visible.

[0056] As shown in FIG. 3 , a cylindrical tubular portion 5a is provided at the right end of the handlebar 5. A cylindrical tubular portion 5b is provided at the left end of the handlebar 5. The axial centers of the tubular portions 5a, 5b extend in the left-right direction and are coaxial with each other. A storage recess 12c is provided in the center of the front wall 12, concave from the outside (front) to the inside (rear). An arc-shaped recess 12d is provided at the top of the storage recess 12c, elongated in the left-right direction and concave in an arc shape facing upward. A pair of handle shafts 12a protruding in the left-right direction and facing each other are provided at the upper right of the storage recess 12c. A pair of handle shafts 12b protruding in the left-right direction and facing each other are provided at the upper left of the storage recess 12c. The tubular portion 5a is fitted between the pair of handle shafts 12a, and the tubular portion 5b is fitted between the pair of handle shafts 12b. As a result, the handle 5 is supported by the front wall 12 so as to be rotatable up and down around the axial center of the cylindrical portions 5a and 5b.

[0057] As shown in Figures 3 and 6, the cylindrical portion 5a on the right side of the handle 5 is provided with an engagement claw 5c that can engage with the cover 3. The engagement claw 5c protrudes upward when the handle 5 is stored. The engagement claw 5c protrudes rearward when the handle 5 is rotated forward. A claw engagement portion 29 that can engage with the engagement claw 5c is provided on the front end surface of the frame portion 23. The claw engagement portion 29 protrudes downward from the lower end of the front end surface of the frame portion 23 at the same lateral position as the engagement claw 5c. The claw engagement portion 29 is formed in a loop shape with a through-hole that penetrates in the front-rear direction. The front wall 12 is provided with an opening 12e in the area that supports the cylindrical portion 5a. The opening 12e is open at the front and upper ends and communicates with both openings. The claw engagement portion 29 can enter from above, and the engagement claw 5c can enter from the front.

[0058] As shown in FIG. 3, when the cover 3 is closed, the claw engagement portion 29 enters the opening 12e from above. At this point, the engagement claw 5c has not yet entered the opening 12e. By rotating the handle 5 forward, the engagement claw 5c enters the opening 12e from the front. The engagement claw 5c then enters the loop portion of the claw engagement portion 29 and engages with the claw engagement portion 29. This keeps the cover 3 closed. Therefore, even if you forget to lock the cover 3 with the locking mechanisms 13 and 14, you can keep the cover 3 closed by rotating the handle 5 to the use position. This prevents small items stored in the power tool accessory case 1 from flying off.

[0059] As shown in FIG. 7 , the fifth small box 35 has a square shape with the same front-to-back length and left-to-right width in a plan view. The first small box 31, the second small box 32, the third small box 33, and the fourth small box 34 are provided based on the size of the fifth small box 35. The first small box 31 has the same size as nine fifth small boxes 35 arranged in a plan view, three in a front-to-back arrangement and three in a left-to-right arrangement, in a total. The second small box 32 has the same size as six fifth small boxes 35 arranged in a plan view, two in a front-to-back arrangement and three in a left-to-right arrangement, in a total. The third small box 33 has the same size as four fifth small boxes 35 arranged in a front-to-back arrangement and two in a left-to-right arrangement, in a total. The fourth small box 34 has the same size as two fifth small boxes 35 arranged in a left-to-right arrangement, in a plan view. Each of the small boxes 31, 32, 33, 34, and 35 has approximately the same height from top to bottom.

[0060] Each of the small boxes 31, 32, 33, 34, and 35 shown in Figure 7 can be removed from the housing 2. The storage positions and orientations of each of the small boxes 31, 32, 33, 34, and 35 are not limited to those shown in the figure. For example, the first small box 31 and the second small box 32 may be stored inside the left side of the housing 2. For example, the third small box 33 and the fifth small box 35 may be stored inside the right side of the housing 2. For example, the second small box 32 and the fourth small box 34 may be stored in an orientation that is long in the front-to-rear direction.

[0061] As shown in FIGS. 20 and 21 , the first small box 31 has a rectangular opening 31a at its upper end. The opening 31a is slightly larger than the rectangular bottom end 31c of the first small box 31. A stepped portion 31b extending parallel to the opening 31a is provided at a position a predetermined distance below the opening 31a. By providing a step in the stepped portion 31b, the inner periphery of the region below the stepped portion 31b is slightly smaller than that of the region above the stepped portion 31b. The bottom wall 31d of the first small box 31 is located above the bottom end 31c. A rectangular rib 31e protruding downward from the bottom wall 31d is provided in the region between the bottom wall 31d and the bottom end 31c. The rectangular rib 31e extends downward to, for example, approximately the same height as the bottom end 31c, so as not to exceed the bottom end 31c. The area between the bottom wall 31d and the lower end 31c is divided into a 3 x 3 grid by rectangular ribs 31e. The lower end 31c and the rectangular ribs 31e are engageable with a plurality of rectangular protrusions 11d (see FIG. 8) provided on the bottom wall 11.

[0062] As shown in FIG. 20, the inner wall of the first small box 31 is provided with insertion ribs 31f extending vertically from the stepped portion 31b to the bottom wall 31d. The insertion ribs 31f are composed of two ribs extending parallel to each other and adjacent to each other. Two sets of insertion ribs 31f are provided on one inner wall, and two sets are provided on the inner wall facing the other inner wall. The two sets of insertion ribs 31f are positioned at approximately the same front-to-back (or left-to-right) positions as the rectangular rib 31e (see FIG. 21) provided on the underside of the bottom wall 31d. In other words, the two sets of insertion ribs 31f are positioned so as to divide the inside of the first small box 31 into approximately three equal parts in the front-to-back (or left-to-right) direction. A separately prepared partition plate 38 can be removably inserted into the insertion ribs 31f.

[0063] As shown in Figures 22 and 23, the second small box 32 has a rectangular opening 32a and a rectangular bottom end 32c that is slightly smaller than the opening 32a. A stepped portion 32b extends parallel to the opening 32a at a position a predetermined distance below the opening 32a. The area below the stepped portion 32b has a slightly smaller inner periphery than the area above the stepped portion 32b. The second small box 32 has a bottom wall 32d located above the bottom end 32c and a rectangular rib 32e protruding downward from the bottom wall 32d. The rectangular rib 32e extends downward between the bottom wall 32d and the bottom end 32c to approximately the same height as the bottom end 32c. The area between the bottom wall 32d and the bottom end 32c is divided into a 3x2 grid by the rectangular rib 32e. The lower end portion 32c and the rectangular rib 32e are engageable with a plurality of rectangular protrusions 11d (see FIG. 8) provided on the bottom wall 11.

[0064] As shown in FIG. 22, the inner wall of the second small box 32 is provided with insertion ribs 32f extending vertically from the stepped portion 32b to the bottom wall 32d. The insertion ribs 32f are composed of two ribs extending parallel to each other next to each other. One set of insertion ribs 32f is provided on each of a pair of opposing inner walls. The insertion ribs 32f are each positioned at approximately the same front-to-back (or left-to-right) position as the rectangular rib 32e (see FIG. 23) provided on the underside of the bottom wall 32d. A separately prepared partition plate 38 can be removably inserted into the insertion ribs 32f.

[0065] As shown in Figures 24 and 25, the third small box 33 has a rectangular opening 33a and a rectangular bottom end 33c that is slightly smaller than the opening 33a. A stepped portion 33b extends parallel to the opening 33a at a position a predetermined distance below the opening 33a. The area below the stepped portion 33b has a slightly smaller inner periphery than the area above the stepped portion 33b. The third small box 33 can be stacked vertically with other small boxes 30, such as other third small boxes 33, using the stepped portion 33b as a base. The third small box 33 has a bottom wall 33d located above the bottom end 33c and a rectangular rib 33e protruding downward from the bottom wall 33d. The rectangular rib 33e extends downward between the bottom wall 33d and the bottom end 33c to approximately the same height as the bottom end 33c. The area between the bottom wall 33d and the lower end 33c is divided into a 2 x 2 grid by rectangular ribs 33e. The lower end 33c and the rectangular ribs 33e are engageable with a plurality of rectangular protrusions 11d (see FIG. 8) provided on the bottom wall 11.

[0066] As shown in Figures 26 and 27, the fourth small box 34 has a rectangular opening 34a and a rectangular bottom end 34c that is slightly smaller than the opening 34a. A stepped portion 34b extending parallel to the opening 34a is provided at a position a predetermined distance below the opening 34a. The area below the stepped portion 34b has a slightly smaller inner periphery than the area above the stepped portion 34b. The fourth small box 34 can be stacked vertically with other small boxes 30, such as other fourth small boxes 34, using the stepped portion 34b as a base. The bottom end 34c extends downward beyond the bottom wall 34d of the fourth small box 34. The bottom end 34c is engageable with multiple rectangular protrusions 11d (see Figure 8) provided on the bottom wall 11.

[0067] As shown in Figures 28 and 29, the fifth small box 35 has a rectangular opening 35a and a rectangular bottom edge 35c that is slightly smaller than the opening 35a. A stepped portion 35b extending parallel to the opening 35a is provided at a position a predetermined distance below the opening 35a. The area below the stepped portion 35b has a slightly smaller inner periphery than the area above the stepped portion 35b. The fifth small box 35 can be stacked vertically with other small boxes 30, such as other fifth small boxes 35, using the stepped portion 35b as a base. The bottom edge 35c extends downward beyond the bottom wall 35d of the fifth small box 35. The bottom edge 35c can engage with multiple rectangular protrusions 11d (see Figure 8) provided on the bottom wall 11. The bottom wall 35d of the fifth small box 35 is positioned higher than the bottom walls of the other small boxes 30 (see Figure 13). Therefore, the user's fingers inserted through the opening 35a can easily reach the vicinity of the bottom wall 35d, making it easy to take out small items stored in the fifth small box 35.

[0068] As described above, the power tool case 1 has a box-shaped housing 2 with an opening 2a at the top, as shown in Figures 1, 10, and 11. The power tool case 1 has a cover 3 that is rotatably connected to the rear wall 19 of the housing 2 to open and close the opening 2a and is made of a light-transmitting material. The power tool case 1 has locking mechanisms 13 and 14 that secure the cover 3 to the housing 2. The power tool case 1 has a right grip 6 that is provided on the right wall 15 of the housing 2. The power tool case 1 has a left grip 7 that is provided on the left wall 17 of the housing 2. The power tool case 1 has a plurality of small boxes 30 that are removably accommodated in the housing 2.

[0069] Therefore, by providing the cover 3 with a light-transmitting material, the inside of the housing 2 can be easily seen when the cover 3 is closed. This makes it easy to see the multiple small boxes 30 housed in the housing 2 and the small items housed in the small boxes 30. Moreover, by holding the right grip portion 6 and the left grip portion 7 with both hands, the user can carry the small power tool case 1 with the cover 3 facing up. This allows the user to carry and place the small power tool case 1 in a position that makes it easy to see the inside of the housing 2 through the cover 3.

[0070] 3, the power tool accessory case 1 has a handle 5 rotatably connected to the front wall of the housing 2. Therefore, a user can easily carry the power tool accessory case 1 by holding the handle 5 with the front wall of the housing 2 facing upward.

[0071] As shown in Figures 13 and 14, the right grip 6 is rotatably connected to the right wall 15. The left grip 7 is rotatably connected to the left wall 17. Therefore, when transporting the power tool case 1, the right grip 6 is rotated to a use position protruding from the right wall 15, and the left grip 7 is rotated to a use position protruding from the left wall 17. This allows the right grip 6 and the left grip 7 to be positioned in a way that makes them easier for the user to hold. When placing or storing the power tool case 1, the right grip 6 is rotated to a storage position following the right wall 15, and the left grip 7 is rotated to a storage position following the left wall 17. This allows the right grip 6 and the left grip 7 to be stored compactly. This improves the convenience of the power tool case 1.

[0072] 13 and 14, the rotation fulcrum 6a of the right grip portion 6 is provided at the upper part of the right grip portion 6. The rotation fulcrum 7a of the left grip portion 7 is provided at the upper part of the left grip portion 7. Therefore, when the right grip portion 6 and the left grip portion 7 are rotated to the use position, the lower part of the right grip portion 6 protrudes rightward beyond the right wall 15, and the lower part of the left grip portion 7 protrudes leftward beyond the left wall 17. Because the upper parts of the right grip portion 6 and the left grip portion 7 are close to the rotation fulcrums 6a and 7a, they are prevented from protruding inward from the housing 2 when in the use position. Therefore, loss of volume of the housing 2 due to the provision of the right grip portion 6 and the left grip portion 7 can be reduced.

[0073] 1 and 18, the cover 3 has an inner holder 28 that holds a nameplate 36 on the inside of the cover 3 (the rear surface of the front end). The nameplate 36 is visible through the cover 3. Therefore, for example, the nameplate 36 can be held in a position adjacent to a small item housed in the power tool accessory case 1. This makes it easy to associate the small item with the nameplate 36 and identify them. Furthermore, by using a cover 3 that has high light transmittance, the nameplate 36 can be clearly seen from the outside of the cover 3.

[0074] 4 and 5, the housing 2 has outer holders 15e and 17e for holding the nameplate 37. Therefore, the wall space of the housing 2 can be effectively utilized to attach the nameplate 37 for identifying small items.

[0075] As shown in Figure 9, the locking mechanisms 13, 14, 16, and 18 have latches 13a, 14a, 16a, and 18a movably mounted on the housing 2 so as to connect another power tool case 40 below the housing 2. Therefore, the latches 13a, 14a, 16a, and 18a can be used to connect another power tool case 40 below the housing 2 of the small power tool case 1. The connected small power tool case 1 and the other power tool case 40 can be carried together by gripping the right grip 6 and the left grip 7 (see Figure 10).

[0076] 2 and 13, the cover 3 has a main plate 22 with a first light transmittance that allows the small box 30 to be viewed. The cover 3 has a frame portion 23 that protrudes upward from the outer periphery of the main plate 22 and has a second light transmittance that is lower than the first light transmittance. Therefore, the main plate 22 is formed in a recess that is lower in height than the frame portion 23. As a result, other power tool cases 40 can be stacked above the frame portion 23 without coming into contact with the main plate 22. This allows the main plate 22 to maintain its high light transmittance.

[0077] Various modifications can be made to the embodiment described above. The light-transmitting cover 3 may be colorless or colored. For example, the main plate 22 may be colorless and the frame portion 23 may be colored. The frame portion 23 may have a high light transmittance that allows the interior of the housing 2 to be clearly visible through the frame portion 23. Alternatively, the frame portion 23 may have a low light transmittance that makes it difficult to see the interior of the housing 2 through the frame portion 23.

[0078] The right grip portion 6 is rotatably supported on the right wall 15, and the left grip portion 7 is rotatably supported on the left wall 17. Alternatively, for example, the right grip portion 6 and the left grip portion 7 may be configured so as not to rotate or move relative to the right wall 15 and the left wall 17. For example, the upper end surfaces of the storage recesses 15a, 17a may be formed into shapes that are easy for a user to grip, and serve as the right grip portion 6 and the left grip portion 7. Alternatively, the right grip portion 6 and the left grip portion 7 may be configured to move between the storage position and the use position by sliding relative to the right wall 15 and the left wall 17, respectively.

[0079] Although small boxes 30 having a variety of shapes, namely, the first small box 31 to the fifth small box 35, have been illustrated, the shapes of the small boxes 30 are not limited to those illustrated. For example, a small box having a size in which three or more fifth small boxes 35 are lined up in the left-right direction may be used. Furthermore, the number of small boxes 30 housed in the housing 2 is not limited to those illustrated. For example, only a plurality of fourth small boxes 34 and a plurality of fifth small boxes 35 may be housed inside the housing 2. For example, the first small box 31 and the second small box 32 may be removed from the housing 2, and a power tool or the like may be housed in the empty space.

[0080] In the illustrated configuration, the rectangular rib 22a of the main plate 22 and the rectangular protrusions 11b, 11c, and 11d of the bottom wall 11 have the same external shape and are spaced equally apart in the front-to-back and left-to-right directions. This configuration allows multiple types of small boxes 30 to be stored and held at any position inside the housing 2. Alternatively, for example, a rectangular rib of approximately the same size as the opening of each small box 30 may be provided on the back surface of the main plate 22, and rectangular protrusions of approximately the same size as the bottom end of each small box 30 may be provided on the upper surface of the bottom wall 11. With this configuration, the space in which each small box 30 is stored is specified. Therefore, small boxes 30 can be quickly stored after being removed from the housing 2.

[0081] In the illustrated configuration, the inner holder 28 is provided on the front end surface of the cover 3. Alternatively or additionally, the inner holder 28 may be provided, for example, on the right end surface or the left end surface of the cover 3. In the illustrated configuration, the outer holder 15e is provided on the right wall 15, and the outer holder 17e is provided on the left wall 17. Alternatively or additionally, the outer holder may be provided, for example, on the rear wall 19 or the bottom wall 11.

[0082] While the small power tool case 1 is shown as being connectable to other power tool cases, the configuration of the present disclosure may be applied to a small power tool case that is not connectable to other power tool cases. [Explanation of symbols]
