[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0014] As shown in FIGS. 1 and 2, a portable tool 1 according to one embodiment of the present invention includes a portable tool body 10 and a portable tool bracket 20 attached to the portable tool body 10.

[0015] The portable tool body 10 may be a tool carried by a worker at a construction site or a building site, such as a tape measure, a flashlight, a water bottle, or a small electronic device (e.g., a mobile phone or a smartphone). In this embodiment, the portable tool body 10 is a tape measure.

[0016] The portable tool body 10, which is a tape measure, has a case body 12 that stores and winds up the steel tape 11 that constitutes the ruler. The case body 12 has a pair of substantially circular side walls 12a centered on the winding axis of the steel tape 11, and a cylindrical peripheral wall 12b connecting these side walls 12a, and has a pull-out opening 12c for the steel tape 11 at its lower end side.

[0017] The portable tool bracket 20 has an attachment portion 21. The portable tool bracket 20 is attached to one side wall 12a of the case body 12 of the portable tool main body 10 at the attachment portion 21.

[0018] The portable tool bracket 20 has an insertion portion 22. The insertion portion 22 is inserted into a guide rail portion 31 provided on a dedicated holder 30 (see FIG. 4) that is held on the user's body, and is detachably attached to the holder 30.

[0019] A user (worker) of the portable tool 1 can attach the insertion portion 22 of the portable tool bracket 20 to a dedicated holder 30, as shown in Figure 3, thereby holding the portable tool 1 in the holder 30 and carrying the portable tool 1 while preventing it from falling.

[0020] More specifically, insertion portion 22 has a generally rectangular shape with a constant width when viewed from the front as shown in Fig. 1, and both sides of the rectangular shape protrude like plates. Insertion portion 22 may be configured such that a tapered guide portion 23 is integrally provided on the tip side in the insertion direction into holder 30.

[0021] As shown in Fig. 4, the holder 30 can be configured to be attached to, for example, a waist belt 2 and held on the user's body. The holder 30 has a pair of guide rails 31 arranged facing each other with a predetermined gap between them on its front side. An upper open space through which the insertion portion 22 is inserted is defined and formed between the pair of guide rails 31 and the main body of the holder 30. A locking stopper 32 that can slide diagonally downward is provided above the pair of guide rails 31.

[0022] 5, the insertion portion 22 of the portable tool bracket 20 is inserted from above between the pair of guide rail portions 31, starting from the guide portion 23 side. At this time, the tapered guide portion 23 is integrally provided on the tip side of the insertion portion 22 in the insertion direction, which makes it easy to insert the insertion portion 22 between the pair of guide rail portions 31.

[0023] The inserting portion 22 inserted between the pair of guide rail portions 31 has its plate-like protruding portions on both sides held by the pair of guide rail portions 31, and its upper end portion is locked from above by the locking stopper 32. As a result, the portable tool bracket 20 is attached to the holder 30 at the inserting portion 22 in a state where it is prevented from coming off.

[0024] The locking stopper 32 can be configured to have a spring or other biasing member (not shown) inside it, and to move diagonally downward against the biasing member when the insertion portion 22 is inserted, and to automatically restore to a position where it locks the upper end of the insertion portion 22 after the insertion portion 22 is inserted between the pair of guide rail portions 31.

[0025] In addition, the portable tool bracket 20 can also be configured to have a recess 23a at the tip of the guide portion 23, so that when the insertion portion 22 is inserted between a pair of guide rail portions 31 and engaged with the locking stopper 32, a pin member 33 provided on the holder 30 engages with the recess 23a to hold the insertion portion 22 in a predetermined position.

[0026] As shown in Figure 6, when the insertion portion 22 is inserted between a pair of guide rail portions 31, the locking stopper 32 can be slid diagonally downward to release the lock of the insertion portion 22 by the locking stopper 32, thereby detaching the insertion portion 22 or the portable tool bracket 20 from the holder 30 and removing the portable tool 1 from the holder 30.

[0027] 2, the portable tool bracket 20 has a notch 24 for hooking and holding in addition to the above-mentioned attachment portion 21 and insertion portion 22. In FIG. 1, the notch 24 is a groove-like opening that opens on the bottom and both the left and right sides of the portable tool bracket 20 and extends from the bottom to the top in a direction parallel to the side wall 12a, allowing it to be hooked onto a waist belt 2, a pocket, a belt-like object, a ring, a string, or other object to be hooked.

[0028] The vertical length, horizontal width, and groove width perpendicular to these dimensions of the notch 24 in FIG. 1 can be set to appropriate dimensions so that the object to be hung can be easily hung.

[0029] Because the portable tool bracket 20 has the notch 24, the user of the portable tool 1 can carry the portable tool 1 by hooking the portable tool bracket 20 to a hooked object such as a waist belt 2 at the notch 24, even if there is no dedicated holder 30, as shown in Figure 7, and holding the portable tool 1 to the hooked object.

[0030] In this way, in the portable tool 1 or the portable tool bracket 20 of this embodiment, the portable tool bracket 20 is configured to have an attachment portion 21 that is attached to the portable tool main body 10, an insertion portion 22 that is inserted into a guide rail portion 31 provided on the holder 30 that is held on the user's body and is removably attached to the holder 30, as well as a notch portion 24 for hanging and holding.Therefore, if a dedicated holder 30 is available, the insertion portion 22 can be attached to the holder 30 and the portable tool 1 can be held in the holder 30, thereby preventing it from falling and allowing it to be carried, and even if a dedicated holder 30 is not available, the portable tool bracket 20 can be hooked onto a hooked object such as a waist belt 2 and the portable tool 1 can be carried.

[0031] As shown in Figure 2, it is preferable that the notch 24 has an opening end 24a on one side (lower side in Figure 2) of the center of gravity G (center of gravity in the vertical direction in Figure 2) of the portable tool body 10, closer to the center of gravity G than the end portion on one side (lower end in Figure 2) of the portable tool body 10, and has an innermost portion 24b on the other side (upper side in Figure 2) of the center of gravity G of the portable tool body 10.

[0032] As a result, when the portable tool 1 is carried by hooking the portable tool bracket 20 onto a hooked object such as a waist belt 2, the center of gravity G of the portable tool body 10 is positioned below the innermost part 24b of the cutout part 24, so that the portable tool 1 can be more stably held on the hooked object such as the waist belt 2.

[0033] As shown in FIG. 2, the notch 24 is preferably provided between the mounting portion 21 and the insertion portion 22.

[0034] This allows the provision of a notch 24 for hooking the portable tool bracket 20 onto an object to be hooked, such as the waist belt 2, without impairing the attachability of the insertion portion 22 to the holder 30.

[0035] The portable tool bracket 20 can be made of at least one of stainless steel, synthetic resin material, glass fiber reinforced plastic, carbon fiber reinforced plastic, and cellulose nanofiber reinforced plastic.

[0036] As shown in Figures 8, 9 and 10, in this embodiment, the bracket 20 for a portable tool has a configuration in which an insertion portion 22 made of a synthetic resin material is fixed to a hook member 25 made of stainless steel.

[0037] The material forming the insertion portion 22 is not limited to synthetic resin material, but may be glass fiber reinforced plastic, carbon fiber reinforced plastic, or cellulose nanofiber reinforced plastic.

[0038] Hook member 25 is formed by bending a stainless steel plate of a predetermined shape, and a portion of it forms plate-shaped mounting portion 21. Hook member 25 also integrally has plate-shaped hook main body 26 that is approximately parallel to mounting portion 21, and curved portion 27 that connects mounting portion 21 and hook main body 26. Curved portion 27 forms innermost portion 24b of cutout portion 24. A predetermined gap is provided between mounting portion 21 and hook main body 26, and this gap forms cutout portion 24.

[0039] The curved portion 27 is shaped to bulge out on the opposite side of the hook main body portion 26 relative to the mounting portion 21, and as shown in Figure 2, when the portable tool bracket 20 is fixed to the side wall 12a, it is arranged to follow the shape of the recess in the side wall 12a.

[0040] 8 and 10, the mounting portion 21 has a pair of through holes 28 aligned in the width direction at a position biased toward the curved portion 27. The mounting portion 21 also has, integrally with the end opposite the curved portion 27, a locking piece 29 that is bent in a stepped shape toward the case body 12.

[0041] As shown in Figures 1 and 2, the portable tool bracket 20 is fixed to one side wall 12a of the case body 12 by inserting a locking piece 29 provided on the mounting portion 21 into a locking hole 12d provided in one side wall 12a of the case body 12 and engaging with the side wall 12a, and by screw members 3 inserted into a pair of through holes 28 provided in the mounting portion 21 and screwed into one side wall 12a of the case body 12.

[0042] In this embodiment, one end of the mounting portion 21 is engaged with the side wall 12a by the locking piece 29, while the other end of the mounting portion 21 is fixed to the side wall 12a with the screw member 3. Therefore, compared to a configuration in which one end of the mounting portion 21 is fixed to the side wall 12a with the screw member 3 without providing the locking piece 29, the portable tool bracket 20 can be strongly fixed to the side wall 12a while preventing damage to the mounting portion 21 and the curved portion 27.

[0043] As shown in Fig. 2, the insertion portion 22 is fixed to the inner surface of the hook body 26, facing the mounting portion 21, on the side of the opening end 24a. More specifically, the insertion portion 22 engages with a claw 26a provided on the hook body 26 and is fixed to the hook body 26 using a rivet 4. The insertion portion 22 protrudes from the inner surface of the hook body 26 toward the mounting portion 21, narrowing the gap on the side of the opening end 24a of the notch 24. As a result, when the portable tool bracket 20 is hooked onto an object to be hooked, such as a waist belt 2, the object is held down by the insertion portion 22 protruding from the hook body 26, thereby preventing the portable tool 1 held by the object from rattling. In addition, an inclined surface 22a is provided on the upper end side (towards the innermost part 24b) of the insertion part 22, which gradually becomes thinner towards the innermost part 24b side, and after the portable tool bracket 20 is hooked onto an object to be hung such as a waist belt 2 at the notch 24, when the portable tool bracket 20 is removed from the object to be hung, the object to be hung is prevented from being caught on the insertion part 22, making it easier to remove the portable tool 1 from the object to be hung.

[0044] The surface of the insertion portion 22 facing the mounting portion 21 may be provided with an anti-slip shape such as grooves, protrusions, or textured surface.

[0045] Furthermore, by configuring the portable tool bracket 20 so that the insertion portion 22 made of synthetic resin material is fixed to the hook member 25 made of stainless steel, the strength of the portable tool bracket 20 can be increased while suppressing wear and tear on the holder 30 into which the insertion portion 22 is inserted.

[0046] Furthermore, the hook body 26 is parallel to the side wall 12a when the portable tool bracket 20 is fixed to the side wall 12a. This causes the insertion portion 22 to extend parallel to the side wall 12a, so that when the portable tool 1 is held in the holder 30, the insertion portion 22 of the portable tool bracket 20 can be more easily inserted into the guide rail portion 31 of the holder 30. Furthermore, the notch 24 also extends parallel to the side wall 12a, so that the portable tool bracket 20 can be easily hooked onto an object to be hung, such as a waist belt 2.

[0047] The present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the spirit and scope of the present invention.

[0048] For example, in the above embodiment, as shown in Fig. 9, a gap is provided between the insertion portion 22 and the attachment portion 21, but as shown in Fig. 11, the thickness of the insertion portion 22 may be increased compared to the case shown in Fig. 9, or as shown in Fig. 12, the hook body 26 may be inclined so as to gradually approach the attachment portion 21 from the curved portion 27 side toward the open end 24a side, so that the insertion portion 22 comes into contact with the attachment portion 21. With such a configuration, when the portable tool bracket 20 is hooked onto an object to be hung, such as a waist belt 2, the object to be hung is firmly sandwiched between the insertion portion 22 and the attachment portion 21, preventing the portable tool 1 from accidentally falling off.

[0049] In the above embodiment, the bracket 20 for a portable tool is configured by fixing the insertion portion 22 made of a synthetic resin material to the hook member 25 made of stainless steel, but this is not limiting and the entire bracket may be configured to be made only of a synthetic resin material, or may be configured to be made of stainless steel. When the bracket 20 for a portable tool is configured to be made entirely of a synthetic resin material, it may be configured to be made of glass fiber reinforced plastic, carbon fiber reinforced plastic, or cellulose nanofiber reinforced plastic instead of synthetic resin.

[0050] Furthermore, in the above embodiment, the portable tool bracket 20 is configured such that the insertion portion 22, which is molded separately from the hook member 25, is fixed to the hook member 25, but it may also be configured such that the insertion portion 22 is molded integrally with the hook member 25 by injection molding of a synthetic resin material using the hook member 25 as an insert.

[0051] Furthermore, the portable tool bracket 20 is not limited to a configuration in which the insertion portion 22 is integrally provided with the tapered guide portion 23 at the tip end in the insertion direction, but may also be a circular insertion portion 22 that is circular in front view, as shown in Fig. 13. In this case, the insertion portion 22 is fixed to the outer surface of the hook body 26 that faces away from the mounting portion 21. With this configuration, the portable tool bracket 20 can be attached to the holder 30 at any angle, eliminating the need to adjust the orientation of the portable tool 1 relative to the holder 30 when holding the portable tool 1 in the holder 30 and making it easier to hold the portable tool 1 in the holder 30.

[0052] Furthermore, in the above embodiment, the mounting portion 21 of the bracket 20 for the portable tool is attached to the case body 12 of the portable tool main body 10 using the screw member 3, but this is not limited to this, and the mounting portion 21 of the bracket 20 for the portable tool can also be fixed to the case body 12 of the portable tool main body 10 by other means such as adhesive or double-sided tape.

[0053] Furthermore, in the above embodiment, the mounting portion 21 of the bracket 20 for the portable tool is configured to have a pair of through holes 28, and the mounting portion 21 is configured to be attached to the case body 12 of the portable tool main body 10 using two screw members 3 inserted into these through holes 28, but this is not limited to this, and the mounting portion 21 may be configured to have one or three or more through holes 28, and the mounting portion 21 may be configured to be attached to the case body 12 of the portable tool main body 10 using one or three or more screw members 3 inserted into these through holes 28.

[0054] Furthermore, the holder 30 is not limited to being attached to the waist belt 2, but may be attached to, for example, a shoulder belt or a belt provided on a bag, a backpack, a tool bag, or the like. [Explanation of symbols]
