FIG. 11 is a perspective view showing another example of the rotation suppressing member; FIG. 9 is a diagram showing a state in which the rotation suppressing member of FIG. 8 is attached to the tool bracket;

Embodiments of the present invention will be exemplified below with reference to the drawings. FIG. 1 is a perspective view showing a state in which a tool bracket 1 according to an embodiment of the present invention is attached to a tape measure M. FIG. The tool bracket 1 is used while being fixed to a tool such as a tape measure M. For example, the tool bracket 1 is detachably attached to a holder body 10 shown in FIG. Here, tools to which the tool bracket 1 can be applied include, in addition to the tape measure M, a hammer, a crowbar, a ratchet wrench, an electric screwdriver, a bag for storing them, a tool holder, and the like.

The tool bracket 1 has an insertion portion 2 that can be inserted into a housing space 13 of a holder body 10 at an arbitrary mounting angle, and a shaft portion 3 and a base portion 4 that are integrally connected to the insertion portion 2 . In this example, the insertion portion 2 is formed in the shape of a flat disc. The shaft portion 3 connects the insertion portion 2 and the base portion 4 and constitutes a rotation axis when the tool bracket 1 rotates with respect to the holder body 10 . Further, the shaft portion 3 of this example is cylindrical, and is arranged so that its central axis is positioned on the same straight line as the central axis of the insertion portion 2 . The base portion 4 is formed in a plate shape extending substantially parallel to the insertion portion 2 . The base portion 4 has an upper surface 4a formed of a curved surface that is arcuate when viewed from the front, a lower surface 4b formed of flat surfaces, and side surfaces 4c and 4d.

A screw hole 5 is formed in the tool bracket 1 of this example. The tool bracket 1 is fixed to the tape measure M by screws that are fastened to the tape measure M through the screw holes 5 . The method of attaching the tool bracket 1 to the tool such as the tape measure M is not particularly limited, and in addition to the method using fasteners such as screws as in this example, it is also possible to fix the tool bracket 1 by adhesion, welding, or the like.

Here, as shown in FIG. 2, the holder main body 10 is held by the user's body by being attached to a band-like wearing body such as a waist belt 11, for example. In addition, as long as the holder main body 10 is held by the user's body, the holding method is not particularly limited. In addition, the band-shaped wearing body is not limited to a horizontal belt that is wrapped around the user's waist, but may be a vertical belt that extends in a substantially vertical direction, such as the vertical belt portion of a harness-type safety belt. It is possible. Moreover, the shape of the holder main body 10 is not particularly limited as long as it can be held by the user's body and the tool bracket 1 can be attached and detached.

The holder main body 10 has a structure for attachment and detachment with respect to a band-shaped attachment. In this example, a through-hole 12 for passing the waist belt 11 is formed on the back side of the holder body 10, but it is not limited to this, and for example, a clip-shaped configuration that sandwiches the waist belt 11 may be used.

The holder main body 10 has a housing space 13 on the front side thereof into which the insertion portion 2 of the tool bracket 1 can be inserted. In this example, the accommodation space 13 is defined by a frame portion 14 that opens upward and a stopper portion 15 that is slidable. The frame portion 14 is configured so that the insertion portion 2 can be inserted from the upper opening 14a. Further, the frame portion 14 is configured to restrict movement of the insertion portion 2 in the front-rear direction, left-right direction, and downward within a predetermined range when the insertion portion 2 is placed in the accommodation space 13 . In addition, although the holder main body 10 of this example has the structure which inserts the insertion part 2 from the upper direction of the accommodation space 13, an insertion direction is not specifically limited.

The stopper portion 15 is configured to slide obliquely downward to open the upper opening 14a when the insertion portion 2 is inserted from above into the housing space 13 . As a result, the entrance to the accommodation space 13 is opened, and the insertion portion 2 can be easily inserted into the accommodation space 13 . A biasing member such as a spring is arranged inside the stopper portion 15 so that the stopper portion 15 automatically returns to its original position after the insertion portion 2 is inserted. The stopper portion 15 can restrict upward movement of the insertion portion 2 arranged in the accommodation space 13 by restoring to its original position.

FIG. 3 is a diagram showing the positions of the insertion portion 2 and the shaft portion 3 in the accommodation space 13 when the insertion portion 2 is inserted into the accommodation space 13 of the holder main body 10 . As shown in FIG. 3, the diameter D1 of the insertion portion 2 is smaller than the width W1 of the accommodation space 13. As shown in FIG. In this example, the insertion portion 2 has a circular plate shape, but is not limited to this, and may be oval or polygonal. Since the maximum width of the insertion portion 2) is smaller than the width W1 of the accommodation space 13, the insertion portion 2 is rotatable within the accommodation space 13. Also, the diameter D1 of the insertion portion 2 is larger than the width W2 of the front opening 14b located on the front side of the frame portion 14, so that the insertion portion 2 does not slip out of the front opening 14b. In addition, although the shape of the insertion part 2 is basically a plate shape with a constant thickness, it is not limited to this, and may be a three-dimensional shape with a non-uniform thickness. Further, the shapes of the shaft portion 3 and the base portion 4 are not particularly limited and can be changed as appropriate, and the base portion 4 is not an essential configuration.

The inserting portion 2 is configured to be insertable into the housing space 13 at an arbitrary mounting angle. That is, as shown in FIG. 1, not only the upright posture in which the lower surface 4b of the base portion 4 faces downward, but also the inverted posture in which the tape measure M and the tool bracket 1 are inverted upside down (posture in which the lower surface 4b of the base portion 4 faces upward). ), or even in a tilted posture between an upright posture and an inverted posture, the insertion portion 2 can be easily inserted into the housing space 13 from the upper opening 14 a of the frame portion 14 . In this example, the maximum diameter of the insertion portion 2 (diameter D1 in this example) is smaller than the width W1 of the housing space 13, and the maximum diameter of the shaft portion 3 (diameter D2 in this example) is in front of the frame portion 14. Since the width W2 is smaller than the width W2 of the opening 14b, there is no restriction on the mounting angle of the insertion portion 2, and the insertion can be performed at any mounting angle.

With such a configuration, the insertion portion 2 can be easily inserted into the housing space 13 of the holder main body 10 without worrying about the orientation of the tool bracket 1 . That is, when a tool such as the tape measure M is attached to the holder main body 10, the tool can be easily attached without adjusting the orientation or changing the grip of the tape measure M. Therefore, it is possible to prevent the work efficiency from being lowered due to the adjustment of the orientation as described above. As described above, according to the tool bracket 1 of the present embodiment, it is possible to easily attach the tool bracket 1 and the tool to the holder body 10 by increasing the degree of freedom of the attachment angle to the holder body 10 .

Further, the tool bracket 1 is configured to be rotatable around the shaft portion 3 with respect to the holder body 10 in a state where it is attached to the holder body 10 . Therefore, the tape measure M fixed to the tool bracket 1 is also rotatable with respect to the holder body 10 . Since the tape measure M is rotatable with respect to the holder body 10, for example, when the measurement tape is pulled out while the tape measure M is attached to the holder body 10, the tape measure M can be measured. Since it can be rotated to an arbitrary angle, the angle at which the measuring tape is pulled out can be changed to a desired angle, which facilitates the measuring work. Further, for example, when the tape measure M attached to the holder body 10 collides with another member or the like, the tape measure M rotates with respect to the holder body 10, so that the impact caused by the collision can be alleviated. The tool bracket 1 in this example is configured so as to be movable in the inserting direction (vertical direction in FIG. 3) while attached to the holder body 10 . That is, the insertion portion 2 of the tool bracket 1 can move vertically within a predetermined range within the housing space 13, but the vertical movement may be suppressed.

It is preferable that the tool bracket 1 is configured to automatically return to a predetermined angle after being rotated with respect to the holder body 10 . According to this, the posture (mounting angle) of the tool such as the tape measure M with respect to the holder main body 10 can be configured to be easy to use and easy to remove, so convenience is improved.

For example, in a state in which the tool bracket 1 fixed to the tape measure M is attached to the holder body 10, the position of the support point S at which the tool bracket 1 is supported by the holder body 10 is located above the center of gravity of the tape measure M. can be In this example, the support point S supported by the holder main body 10 is the position of the outer peripheral surface of the shaft portion 3 supported by the lower edge portion 14c of the front opening 14b of the frame portion 14, as shown in FIG. be. With such a configuration, the tape measure M is supported by the holder body 10 at the support point S above the center of gravity. As a result, since the gravity acting on the tape measure M acts in a direction to maintain the posture of the tape measure M at a predetermined angle (to return it to its original position when rotated), the tape measure M automatically maintains a fixed posture. will return to More specifically, the tool bracket 1 returns to a predetermined posture in which the center of gravity of the tape measure M is arranged directly below the support point S, and stops.

In addition, as shown in FIG. 4, by providing a flat surface 3a on the outer peripheral surface of the shaft portion 3 and arranging the flat surface 3a so as to contact the lower edge portion 14c of the front opening 14b of the frame portion 14, Rotation of the tool bracket 1 about the shaft portion 3 with respect to the holder body 10 can be restricted to some extent. Further, the shaft portion 3 may be provided with a plurality of flat surfaces on its outer peripheral surface. Furthermore, the shaft portion 3 may have a polygonal columnar shape with a polygonal cross section.

As a construction for automatically returning the tool bracket 1 to a predetermined posture, a method of utilizing elastic pieces 2a and 2b provided in the insertion portion 2 as shown in FIGS. 5(a) and 5(b). There is also In the example shown in FIGS. 5(a) and 5(b), a pair of left and right notch portions 2c are formed in the insertion portion 2 to provide elastically deformable elastic pieces 2a and 2b on both left and right sides, respectively. The tool bracket 1 rotates around the shaft portion 3 from the posture shown in FIG. 5(a), and as shown in FIG. When deformed, the restoring force of the elastic piece 2a automatically returns to the predetermined posture (mounting angle) shown in FIG. 5(a). When the tool bracket 1 rotates in the direction opposite to that in FIG. 5(b), the elastic piece 2b on the side opposite to the elastic piece 2a elastically deformed in FIG. 5(b) is elastically deformed. , returns to the state shown in FIG. 5(a) by the restoring force. 5A and 5B, the insertion portion 2 is provided with the elastic pieces 2a and 2b, but the shaft portion 3 may be provided with similar elastic pieces.

Further, as a configuration for automatically returning the tool bracket 1 to a predetermined posture, magnets are arranged in the holder body 10 and the tool bracket 1 respectively, and the attraction or repulsion force between the magnets is used. Alternatively, the posture (mounting angle) of the tool bracket 1 with respect to the holder body 10 may return to the desired angle. For example, a magnet is arranged on a part of the outer peripheral surface of the shaft portion 3 of the tool bracket 1, and a magnet is arranged at a corresponding position on the inner edge portion of the frame portion 14 of the holder body 10, and these magnets attract each other. Thus, the tool bracket 1 can be configured to return to a predetermined posture.

Here, it is possible to suppress rotation of the tape measure M attached to the holder body 10 by using rotation suppressing members 20 and 30 shown in FIGS. 6 to 9, for example.

The rotation suppressing member 20 shown in FIG. 6 includes a main plate portion 21 inserted into the accommodation space 13 of the holder body 10, a support portion 22 projecting forward from the main plate portion 21, and a pair of projections projecting downward from the support portion 22. a portion 23; A concave curved surface 21 a is provided on the upper surface of the main plate portion 21 . The curved surface 21a has a shape corresponding to the outer peripheral surface of the insertion portion 2, and is formed in an arc shape having substantially the same diameter as the outer peripheral surface of the insertion portion 2 in a front view in this example. The rotation suppressing member 20 can be attached to the holder body 10 by inserting the main plate portion 21 into the housing space 13 through the upper opening 14 a of the frame portion 14 of the holder body 10 .

FIG. 7 shows a state in which the rotation suppressing member 20 is attached alone to the holder body 10, and further shows the insertion portion 2 and the base portion 4 when the insertion portion 2 of the tool bracket 1 is inserted into the housing space 13. It is indicated by a two-dot chain line. In this state, the rotation suppressing member 20 is held against the holder body 10 so as to prevent it from slipping off, and the tool bracket 1 is suppressed from rotating by the rotation suppressing member 20 . As a result, the rotation of the tool bracket 1 with respect to the holder body 10 is suppressed.

Specifically, the main plate portion 21 is retained in the accommodation space 13 in a state in which rotation is suppressed. The support portion 22 is provided with an upward support surface 22 a that contacts the lower surface 4 b of the base portion 4 of the tool bracket 1 . The lower surface 4b of the base portion 4 indicated by a two-dot chain line in FIG. 7 contacts the support surface 22a of the tool bracket 1, thereby suppressing the rotation of the tool bracket 1 with respect to the rotation suppressing member 20. As shown in FIG. The outer peripheral surface of the insertion portion 2 abuts against the curved surface 21a. The shape of the support portion 22 is formed so as to be fitted into the front opening 14b of the frame portion 14 in the holder main body 10, and the lower surface 22b of the support portion 22 contacts the lower edge portion 14c of the frame portion 14. supported by Also, the pair of protrusions 23 are arranged on the front side of the frame portion 14 . The frame portion 14 is sandwiched between the pair of projecting portions 23 and the main plate portion 21 to restrict rattling of the rotation suppressing member 20 .

FIG. 8 shows a rotation suppressing member 30 as another example. The rotation suppressing member 30 has a main body plate portion 31 having an opening 31 a into which the base portion 4 can be fitted, and a protruding portion 32 protruding from the main body plate portion 31 to one side. The protruding portion 32 is shaped so as to be fitted into the front opening 14b of the frame portion 14 of the holder body 10 . The projecting portion 32 is provided with a concave curved surface 32a having the same shape as the curved surface 21a of the rotation suppressing member 20 shown in FIG.

As shown in FIG. 9, the rotation suppressing member 30 of this example is attached to the holder main body 10 together with the tool bracket 1 in a state of being fitted in the tool bracket 1 fixed to the tape measure M. As shown in FIG. It should be noted that the rotation suppressing member 30 of this example cannot be attached to the holder body 10 by itself.

When the rotation suppressing member 30 is attached to the holder main body 10 together with the tool bracket 1, the rotation suppressing member 30 is held in a state in which rotation is suppressed with respect to the holder main body 10, and the tool bracket 1 is attached to the rotation suppressing member. Rotation is suppressed by 30 . As a result, the rotation of the tool bracket 1 with respect to the holder body 10 is suppressed.
