DETAILED DESCRIPTION OF THE INVENTION

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings, in which: FIG.

[0010] (Embodiment 1) <Adapter configuration> FIG. 1 is a schematic perspective view of a tool holder 100 according to the first embodiment, showing the front surface 11a of the main body 10. FIG. 2 is a schematic perspective view of the tool holder 100 according to the first embodiment, showing the back surface 11b of the main body 10. FIG. 3 is a schematic rear view of the tool holder 100 according to the first embodiment. FIG. 4 is a schematic side view of the tool holder 100 according to the first embodiment. FIG. 5 is a schematic cross-sectional view taken along line VV in FIG. 3. FIG. 11 is a schematic cross-sectional view of the tool holder 100 according to the first embodiment, showing a state in which a tape measure is attached to the tool holder 100. Note that FIGS. 1 to 5 show a state in which the first movable member 21 and the second movable member 22 are disposed at positions capable of holding the belt 101. In FIG. 11, the tape measure as the tool 102 is indicated by a dotted line.

[0011] The tool holder 100 of this embodiment is attached to a belt 101 to hold a tool 102. The following description will be given taking as an example a case where a tape measure is used as the tool 102, but the tool 102 is not limited to a tape measure and may be a utility knife or the like. A tape measure is attached to the tool holder 100 as the tool 102 (see FIG. 11). The tool holder 100 is attached to a belt 101 (see FIGS. 9 and 10). The belt 101 is inserted into a belt loop of trousers, but the trousers are not shown in FIGS. 9 and 11 for clarity.

[0012] 1 and 2, the tool holder 100 mainly includes a main body 10, a first movable member 21, and a second movable member 22. The first movable member 21 is rotatably attached to an upper end 10a of the main body 10. The second movable member 22 is rotatably attached to a lower end 10b of the main body 10. The lower end 10b of the main body 10 is located opposite the upper end 10a.

[0013] The main body 10 has a front surface 11a and a rear surface 11b. In the main body 10, the rear surface 11b is located opposite the front surface 11a in the z direction. As shown in FIG. 1, the front surface 11a is formed by the surface of the cover member 12. As shown in FIG. 2, the rear surface 11b is formed by the surface of the support member 11.

[0014] Hereinafter, as shown in FIG. 3, the direction perpendicular to the rear surface 11b is defined as the z direction. The direction in which the upper end portion 10a is disposed as viewed from the lower end portion 10b is defined as the x direction. The direction perpendicular to both the x direction and the z direction is defined as the y direction. In other words, the rear surface 11b extends along the x direction and the y direction.

[0015] The tool 102 is configured to be held by the main body 10 (see FIG. 11). Specifically, the main body 10 has a support member 11, a cover member 12, and a switch unit 13. The support member 11 and the cover member 12 form a first internal space Q1. By placing a tape measure adapter or the like in the first internal space Q1, the main body 10 can hold the tool 102.

[0016] An opening N1 is formed near the upper end 10a of the main body 10. The opening N1 is in communication with the first internal space Q1. The opening N1 is formed by a support member 11, a cover member 12, and a switch unit 13. By inserting a tape measure adapter or the like through the opening N1, the tool 102 can be placed in the first internal space Q1.

[0017] 1, a cutout N2 is provided in the cover member 12. The cutout N2 is located in the center in the y direction of the cover member 12. Thus, the shape of the cover member 12 in a plan view of the front surface 11a is U-shaped.

[0018] The notch N2 extends in the x direction. A tape measure adapter or the like inserted through the opening N1 moves within the first internal space Q1 in the direction in which the notch N2 extends. When the tape measure adapter or the like is placed in the first internal space Q1, the notch N2 controls the movement of the tool 102 in the y direction.

[0019] A portion of the notch N2 near the opening N1 is inclined in the y direction. This causes the width of the notch N2 in the y direction to narrow from the upper end 10a to the lower end 10b. This makes it easier to insert a tape measure adapter or the like through the opening N1.

[0020] The switch unit 13 is provided at the upper end 10a of the main body 10. The switch unit 13 is configured to allow the tool 102 held therein to be attached and detached. Specifically, the switch unit 13 includes a pressing portion 13a and a fixing portion 13b. The fixing portion 13b is inclined relative to the pressing portion 13a. The fixing portion 13b is configured integrally with the pressing portion 13a. Therefore, when the pressing portion 13a is pressed along the z direction, the fixing portion 13b moves in conjunction with the movement of the pressing portion 13a. In other words, when the pressing portion 13a is pressed along the z direction, the fixing portion 13b protrudes from the support member 11 into the first internal space Q1. The protrusion of the fixing portion 13b into the first internal space Q1 controls the movement of the tool 102 in the x direction. In this manner, the tool 102 is held by the main body 10.

[0021] By pressing the pressing portion 13a in the -z direction, the fixing portion 13b that protruded from the support member 11 into the first internal space Q1 is stored in the support member 11. By storing the fixing portion 13b in the support member 11, the tool 102 can be removed from the main body 10.

[0022] The first movable member 21 and the second movable member 22 are configured to be rotatable to positions that can hold the belt 101. Specifically, the first movable member 21 is attached to the upper end portion 10a of the main body 10 using a first shaft portion 41. The central axis A1 of the first shaft portion 41 extends along the y direction. The first movable member 21 is rotatable around the central axis A1.

[0023] The second movable member 22 is attached to the lower end 10b of the main body 10 using a second shaft 42. The central axis A2 of the second shaft 42 extends along the y direction. The second movable member 22 is rotatable around the central axis A2. The second movable member 22 extends in the y direction.

[0024] 2, when the first movable member 21 and the second movable member 22 are positioned so as to be able to hold the belt 101, a second internal space Q2 is formed by the support member 11 of the main body 10 and the first movable member 21. From a different perspective, the second internal space Q2 is an area surrounded by an inner surface S1 (described later) and a back surface 11b. By inserting the belt 101 into the second internal space Q2, the tool holder 100 is attached to the belt 101 (see FIGS. 9 and 10).

[0025] The first movable member 21 includes a pair of plate portions 21a and a connecting portion 21b. As shown in FIG. 3, the pair of plate portions 21a extend from the upper end portion 10a toward the lower end portion 10b at a position where the belt 101 can be held. The pair of plate portions 21a are spaced apart from each other in a direction (y direction) perpendicular to the direction in which the plate portions 21a extend (x direction in FIG. 3) when viewed from above on the back surface 11b. In this manner, a space is formed between the pair of plate portions 21a. Therefore, the tool holder 100 can be attached to the belt 101 so that a belt loop is disposed in the space. From a different perspective, the tool holder 100 can be attached to the belt 101 so that the pair of plate portions 21a sandwich the belt loop in the y direction.

[0026] The connecting portion 21b is connected to the pair of plate portions 21a. The connecting portion 21b extends along the y direction. The connecting portion 21b is disposed near the upper end portion 10a. Because the pair of plate portions 21a are connected by the connecting portion 21b, the pair of plate portions 21a move in conjunction with each other. In this way, when the first movable member 21 is in a position where it can hold the belt 101, the shape of the first movable member 21 in a plan view of the back surface 11b may be U-shaped.

[0027] 5, the first movable member 21 has an inner surface S1 and an outer surface S2. The outer surface S2 of the first movable member 21 is the surface located opposite the inner surface S1. When the first movable member 21 is in a position where it can hold the belt 101, the inner surface S1 faces the back surface 11b of the main body 10. In other words, when the first movable member 21 is in a position where it can hold the belt 101, the back surface 11b of the main body 10 faces the inner surface S1 of the first movable member 21.

[0028] The outer surface S2 includes a first inclined surface S21, a second inclined surface S22, and a parallel surface S23. The parallel surface S23 extends in a direction parallel to the back surface 11b (for example, the x direction in FIG. 5) at a position where the belt 101 can be held.

[0029] 5, first inclined surface S21 contacts second movable member 22 at a position capable of holding belt 101. Second inclined surface S22 is continuous with parallel surface S23 and first inclined surface S21.

[0030] Here, a feature of the tool holder 100 according to the first embodiment is that, as shown in FIG. 5, the first inclined surface S21 is inclined with respect to the back surface 11b at a position where the belt 101 can be held. The inclination angle θ of the first inclined surface S21 with respect to the back surface 11b may be, for example, greater than 0°. With this configuration, even if an external force is applied to the first movable member 21 in a direction in which the first inclined surface S21 moves away from the back surface 11b (direction R1 in FIG. 5), a force is applied from the first movable member 21 to the second movable member 22 so that the second movable member 22 moves in a direction in which the second movable member 22 closes (direction R2 in FIG. 5). In other words, even if an external force is applied to the tool holder 100 so as to open the first movable member 21, the second movable member 22 restricts the movement of the first movable member 21, and the first movable member 21 and the second movable member 22 are fixed at positions where the belt 101 can be held. As a result, the tool holder 100 is prevented from falling off the belt 101.

[0031] The second inclined surface S22 is inclined with respect to the first inclined surface S21. The inclination angle of the second inclined surface S22 with respect to the first inclined surface S21 may be, for example, greater than 0°, and may be 45°, 90°, or 135°. By doing so, even if a force is applied from the first movable member 21 to the second movable member 22 so as to move the second movable member 22 in the closing direction (direction R2 in FIG. 5), the second inclined surface S22 is inclined with respect to the first inclined surface S21, and therefore the movement of the second movable member 22 is limited by the second inclined surface S22.

[0032] As shown in FIG. 4, the first movable member 21 may include a claw portion 25. The claw portion 25 is disposed at the tip of the pair of plate portions 21a. Specifically, when the belt 101 can be held, the claw portion 25 is disposed at a position opposite the upper end portion 10a with respect to the second movable member 22. The claw portion 25 is provided so as to be continuous with the first inclined surface S21. In this manner, even if a force acts on the second movable member 22 so as to move the second movable member 22 in a direction in which the second movable member 22 opens (a direction opposite to the R2 direction in FIG. 5), the movement of the second movable member 22 is restricted by the claw portion 25.

[0033] 5, the main body 10 may include an elastic body 15. The elastic body 15 presses the first movable member 21 from the rear surface 11b toward the first movable member 21 at a position where the belt 101 can be held. Specifically, from a different perspective, the elastic body 15 presses the first movable member 21 along a direction in which the first movable member 21 opens (direction R1 in FIG. 5) at a position where the belt 101 can be held.

[0034] The material constituting the elastic body 15 may be any material as long as it is elastically deformable. The elastic body 15 may be a leaf spring or a spring. For example, the elastic body 15 may be arranged so as to press against the surface of the inner surface S1 that is located opposite the first inclined surface S21. In this manner, an external force is applied to the first movable member 21 so as to open the first movable member 21, and therefore the movement of the first movable member 21 is restricted by the second movable member 22 and the elastic body 15.

[0035] At least one of the first movable member 21 and the second movable member 22 may be made of a metal. This prevents the first movable member 21 and the second movable member 22 from being damaged even if a strong impact or external force is applied to the tool holder 100. In other words, the first movable member 21 and the second movable member 22 are prevented from being damaged and falling off the tool holder 100.

[0036] <Operation of the first movable member and the second movable member> Next, the operation of the tool holder 100 according to the first embodiment will be described. Fig. 6 is a schematic perspective view showing a state in which the first movable member 21 and the second movable member 22 in the tool holder 100 according to the first embodiment are arranged in positions where the belt 101 can be attached and detached. Fig. 7 is a schematic side view showing a state in which the first movable member 21 and the second movable member 22 in the tool holder 100 according to the first embodiment are arranged in positions where the belt 101 can be attached and detached. Fig. 8 is a schematic side view showing a state in which the first movable member 21 in the tool holder 100 according to the first embodiment is arranged in a position where the belt 101 can be held.

[0037] First, as shown in Figures 6 and 7, the first movable member 21 and the second movable member 22 are arranged in positions where the belt 101 can be attached and detached. Specifically, the first movable member 21 is arranged so as to be spaced apart from the elastic body 15. In this state, as shown in Figure 7, the belt 101 is arranged in the second internal space Q2. The belt 101 is arranged so that the direction in which the belt 101 extends is along the y direction. Note that in Figures 7 and 8, the belt 101 is shown by a dashed line.

[0038] Next, first movable member 21 is positioned at a position where it can hold belt 101. Specifically, first movable member 21 is rotated in the direction in which first movable member 21 closes (direction R3 in FIG. 7). In this way, by rotating first movable member 21 so that first movable member 21 comes into contact with elastic body 15 as shown in FIG. 8, first movable member 21 is positioned at a position where it can hold belt 101. Belt 101 is positioned so that the longitudinal direction of belt 101 is aligned with the y direction and the lateral direction of belt 101 is aligned with the x direction. Elastic body 15 presses, for example, the surface of inner surface S1 that is located opposite first inclined surface S21.

[0039] Next, the second movable member 22 is positioned at a position where it can hold the belt 101. Specifically, the second movable member 22 is rotated in the direction in which the second movable member 22 closes (direction R4 in FIG. 8). Pressing the first movable member 21 deforms the elastic body 15. Therefore, when the second movable member 22 is rotated in direction R4, the elastic body 15 is elastically deformed, allowing the second movable member 22 to rotate to a position where it can hold the belt 101. In this manner, the second movable member 22 is rotated so that it contacts the first inclined surface S21. As a result, as shown in FIGS. 1 to 5, the first movable member 21 and the second movable member 22 are positioned at positions where they can hold the belt 101.

[0040] 9 is a schematic perspective view of the tool holder 100 according to the first embodiment, showing a state in which the tool holder 100 is attached to a belt 101. FIG. 10 is a schematic cross-sectional view taken along line XX in FIG.

[0041] 9 and 10, the first movable member 21 may include a rib 23. The rib 23 is provided so as to protrude toward the main body portion 10. Specifically, the rib 23 protrudes from the inner surface S1 into the second internal space Q2. The rib 23 is provided on each of the pair of plate portions 21a. The rib 23 is provided on an end of the plate portion 21a in the y direction, and the rib 23 may be formed by bending a portion of the plate portion 21a.

[0042] The belt 101 is inserted into the second internal space Q2 along the y direction. As shown in Fig. 10, the ribs 23 protruding into the second internal space Q2 bite into the belt 101 in the z direction. In this way, a normal stress is applied to the belt 101 from the ribs 23, and the movement of the belt 101 in the y direction is controlled.

[0043] <Sim Configuration> Next, the configuration of the shim 14 will be described. Fig. 12 is a schematic exploded perspective view of the tool holder 100 according to the first embodiment. Fig. 13 is a schematic perspective view showing the shim 14 of the tool holder 100 according to the first embodiment attached to the back surface 11b.

[0044] 12, the main body 10 may include a shim 14. The shim 14 is detachably attached to the rear surface 11b. The shim 14 includes a plurality of protrusions 16. Specifically, the shim 14 has a flat portion 14a and an insertion portion 14b.

[0045] A plurality of protrusions 16 are provided on the surface of the flat portion 14a. When the shim 14 is attached to the back surface 11b, the plurality of protrusions 16 protrude toward the first movable member 21 at positions where the belt 101 can be held.

[0046] The multiple protrusions 16 have different heights. Specifically, the multiple protrusions 16 include multiple first protrusions 16a and multiple second protrusions 16b. The heights of the first protrusions 16a and the second protrusions 16b are different from each other, and the height of the first protrusions 16a is greater than the height of the second protrusions 16b. The multiple first protrusions 16a are arranged in a straight line on the surface of the flat portion 14a. The multiple second protrusions 16b are arranged in a straight line on the surface of the flat portion 14a.

[0047] 12, in a plan view of the surface of the flat portion 14a, the first protrusion 16a is positioned at a 90° angle in the circumferential direction relative to the second protrusion 16b around the central axis A3 of the flat portion 14a. The central axis A3 extends along the z direction. The positions of the multiple protrusions 16 can be changed by rotating the shim 14.

[0048] The insertion portion 14b is continuous with the rear surface of the flat portion 14a. The insertion portion 14b is inserted into a through hole H provided in the main body portion 10. The through hole H is formed so as to extend from the front surface 11a to the rear surface 11b. In a plan view of the rear surface 11b, the shape of the through hole H is circular. The shape of the insertion portion 14b is cylindrical. The insertion portion 14b extends from the rear surface of the flat portion 14a in the -z direction.

[0049] A plurality of protrusions 17 are provided on the side surface of the insertion portion 14b. The plurality of protrusions 17 are arranged at positions that are 90° apart in the circumferential direction around the central axis A3 of the flat portion 14a, and are arranged at equal intervals in the circumferential direction.

[0050] A plurality of grooves are provided in the through-hole H. The insertion portion 14b is inserted into the through-hole H so that the protrusion 17 passes through the grooves. In this manner, the shim 14 can be attached to the back surface 11b as shown in FIG.

[0051] The shim 14 attached to the back surface 11b in this manner can rotate about the central axis A3. By rotating the shim 14 45 degrees about the central axis A3, the size of the gap CL in which the belt 101 is disposed can be adjusted. Furthermore, by rotating the shim 14 45 degrees about the central axis A3, the movement of the shim 14 in the z direction is limited by the protrusions 17, and the shim 14 is fixed to the main body 10. In this manner, the shim 14 is configured to be rotatable so that the positions of the multiple protrusions 16 can be changed.

[0052] Fig. 14 is a schematic perspective view showing a state in which the shim 14 of the tool holder 100 according to the first embodiment is attached to the back surface 11b at a first angle. Fig. 15 is a schematic partially enlarged cross-sectional view showing a state in which the shim 14 of the tool holder 100 according to the first embodiment is attached to the back surface 11b at a first angle. Figs. 14 and 15 show a state in which the shim 14 is arranged in the tool holder 100 according to the first embodiment so that the gap CL is minimized.

[0053] As shown in Fig. 14, the shim 14 is attached to the tool holder 100 so that the first protrusions 16a are located on both ends of the flat portion 14a in the y direction. As shown in Fig. 15, at a position where the belt 101 can be held, a gap CL in which the belt 101 is located is formed between the first protrusions 16a and the inner surface S1. The gap CL between the first protrusions 16a and the inner surface S1 is, for example, 1.2 mm.

[0054] Fig. 16 is a schematic perspective view showing a state in which the shim 14 of the tool holder 100 according to the first embodiment is attached to the rear surface 11b at a second angle. Fig. 16 corresponds to Fig. 14. Fig. 17 is a schematic partially enlarged cross-sectional view showing a state in which the shim 14 of the tool holder 100 according to the first embodiment is attached to the rear surface 11b at a second angle. Fig. 17 corresponds to Fig. 15. Figs. 16 and 17 show a state in which the shim 14 is arranged so that the size of the gap CL is larger than the size of the gap CL shown in Figs. 14 and 15.

[0055] As shown in Fig. 16, the shim 14 is attached to the tool holder 100 so that the second convex portions 16b are located on both ends of the flat portion 14a in the y direction. As shown in Fig. 17, at a position where the belt 101 can be held, a gap CL in which the belt 101 is located is formed between the second convex portions 16b and the inner surface S1. The gap CL between the second convex portions 16b and the inner surface S1 is, for example, 1.7 mm.

[0056] In this way, the size of the gap CL in which the belt 101 is disposed can be adjusted by rotating the shim 14. By adjusting the size of the gap CL, the degree to which the belt 101 is pinched can be adjusted.

[0057] Fig. 18 is a schematic perspective view showing a state in which the shim 14 of the tool holder 100 according to the first embodiment has been removed. Fig. 18 corresponds to Fig. 16. Fig. 19 is a schematic partially enlarged sectional view showing a state in which the shim 14 of the tool holder 100 according to the first embodiment has been removed. Fig. 19 corresponds to Fig. 17. As shown in Figs. 18 and 19, the shim 14 does not have to be attached to the tool holder 100 according to the first embodiment.

[0058] This further increases the gap CL in which the belt 101 is disposed. Specifically, the gap CL in which the belt 101 is disposed is formed between the back surface 11b and the inner surface S1 at a position where the belt 101 can be held. The gap CL between the back surface 11b and the inner surface S1 is, for example, 4.5 mm.

[0059] In this way, the shim 14 is configured to be detachable from the back surface 11b, so that the size of the gap CL in which the belt 101 is disposed can be adjusted in three stages.

[0060] <Action and effect> A tool holder 100 according to the present invention is a tool holder 100 for holding a tool 102 while attached to a belt 101. The tool holder 100 includes a main body 10, a first movable member 21, and a second movable member 22. The tool 102 is held by the main body 10. The first movable member 21 is rotatably attached to an upper end 10a of the main body 10. The second movable member 22 is rotatably attached to a lower end 10b of the main body 10. The first movable member 21 and the second movable member 22 are configured to be rotatable to positions where they can hold the belt 101. In the position where they can hold the belt 101, the main body 10 has a back surface 11b that faces the first movable member 21. In the position where they can hold the belt 101, the first movable member 21 has a first inclined surface S21 that contacts the second movable member 22. At the position where the belt 101 can be held, the first inclined surface S21 is inclined with respect to the rear surface 11b.

[0061] In this way, even if an external force is applied to the tool holder 100 so as to open the first movable member 21, the movement of the first movable member 21 is restricted by the second movable member 22, and the first movable member 21 and the second movable member 22 are fixed in positions where they can hold the belt 101. As a result, the tool holder 100 is prevented from falling off the belt 101.

[0062] According to the tool holder 100, the first movable member 21 has a parallel surface S23 and a second inclined surface S22. At the position where the belt 101 can be held, the parallel surface S23 extends in a direction parallel to the back surface 11b. At the position where the belt 101 can be held, the second inclined surface S22 is continuous with the parallel surface S23 and the first inclined surface S21. The second inclined surface S22 is inclined with respect to the first inclined surface S21.

[0063] In this way, even if a force acts from the first movable member 21 to the second movable member 22 so as to move the second movable member 22 in the closing direction (direction R2 in Figure 5), the second inclined surface S22 is inclined relative to the first inclined surface S21, and therefore the movement of the second movable member 22 is restricted by the second inclined surface S22.

[0064] According to the tool holder 100, the first movable member 21 includes a claw portion 25. When the first movable member 21 is at a position capable of holding the belt 101, the claw portion 25 is disposed at a position opposite the upper end portion 10a of the second movable member 22. The claw portion 25 is configured to fix the second movable member 22.

[0065] In this way, even if a force acts on the second movable member 22 so as to move the second movable member 22 in the direction in which the second movable member 22 opens (the direction opposite to the R2 direction in Figure 5), the movement of the second movable member 22 is restricted by the claw portion 25.

[0066] According to the tool holder 100, the main body 10 includes the elastic body 15. The elastic body 15 presses the first movable member 21 from the back surface 11b toward the first movable member 21 at a position where the belt 101 can be held.

[0067] In this way, an external force is applied to the first movable member 21 by the elastic body 15 so that the first movable member 21 opens, and therefore the movement of the first movable member 21 is restricted by the second movable member 22 and the elastic body 15.

[0068] According to the tool holder 100, the first movable member 21 includes a pair of plate portions 21a. The plate portions 21a extend from the upper end portion 10a to the lower end portion 10b at a position where the belt 101 can be held. The pair of plate portions 21a are arranged spaced apart from each other in a direction perpendicular to the direction in which the plate portions 21a extend in a plan view of the back surface 11b.

[0069] In this way, a space is formed between the pair of plate portions 21a. Therefore, the tool holder 100 can be attached to the belt 101 so that the belt loop is disposed in the space. From a different perspective, the tool holder 100 can be attached to the belt 101 so that the pair of plate portions 21a sandwich the belt loop in the y direction.

[0070] According to the tool holder 100, the first movable member 21 includes the rib 23 provided so as to protrude toward the main body portion 10.

[0071] In this way, a normal stress is applied to the belt 101 from the ribs 23, and the movement of the belt 101 in the y direction is controlled.

[0072] According to the tool holder 100, the main body 10 includes a shim 14. The shim 14 is detachably attached to the back surface 11b. The shim 14 protrudes toward the first movable member 21 at a position where it can hold the belt 101. The shim 14 includes a plurality of protrusions 16 that are different in height from one another. The shim 14 is configured to be rotatable so that the positions of the plurality of protrusions 16 can be changed.

[0073] This makes it possible to adjust the size of the gap CL in which the belt 101 is disposed. By adjusting the size of the gap CL, it is possible to adjust the degree to which the belt 101 is pinched.

[0074] According to the tool holder 100, at least one of the first movable member 21 and the second movable member 22 is made of a metal material.

[0075] This prevents the first movable member 21 and the second movable member 22 from being damaged even if a strong impact or external force is applied to the tool holder 100. In other words, the first movable member 21 and the second movable member 22 are prevented from being damaged and falling off the tool holder 100.
