  Hereinafter, embodiments of the present invention will be described 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 mounted on a tape measure M. FIG. The tool bracket 1 is used in a state of being fixed to a tool such as a tape measure M, and is a member that is detachably attached to the holder main body 10 shown in FIG. Here, the tool to which the tool bracket 1 can be applied includes, in addition to the tape measure M, a hammer, a bar, a ratchet wrench, an electric screwdriver, a bag for storing them, a tool insert, and the like.

  The tool bracket 1 includes an insertion portion 2 that can be inserted into the accommodation space 13 of the 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 part 2 is formed in a flat disk shape. The shaft portion 3 connects the insertion portion 2 and the base portion 4 and constitutes a rotation shaft when the tool bracket 1 rotates with respect to the holder body 10. Further, the shaft portion 3 of this example has a columnar shape, and is arranged so that its central axis is located on the same straight line as the central axis of the insertion portion 2. The base portion 4 is formed in a plate shape that extends substantially parallel to the insertion portion 2. The base portion 4 has an upper surface 4a configured by a curved surface that is arcuate in a front view, a lower surface 4b configured by a flat surface, and both 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 a screw fastened to the tape measure M through the screw hole 5. The method for attaching the tool bracket 1 to a tool such as the tape measure M is not particularly limited, and it can be fixed by adhesion, welding, or the like in addition to the method using a fastener such as a screw as in this example.

  Here, as shown in FIG. 2, the holder main body 10 is held on the user's body by being attached to a belt-like attached body such as a waist belt 11. In addition, if the holder main body 10 is hold | maintained at a user's body, the holding method will not be specifically limited. Further, the belt-shaped body is not limited to a horizontal belt wound around the user's waist, but may be a vertical belt extending in a substantially vertical direction, such as a vertical belt portion of a harness-type safety belt, for example. Is possible. The shape of the holder body 10 is not particularly limited as long as it is held by the user's body and the tool bracket 1 can be attached and detached.

  The holder main body 10 has a configuration for attaching to and detaching from the belt-shaped mounted body. In this example, the through hole 12 for allowing the waist belt 11 to pass is formed on the back side of the holder main body 10. However, the present invention is not limited to this. For example, a clip-like configuration that sandwiches the waist belt 11 may be used.

  The holder main body 10 has an accommodation space 13 into which the insertion part 2 of the tool bracket 1 can be inserted on the front side. In this example, the accommodating space 13 is defined by a frame portion 14 that opens upward and a stopper portion 15 that is configured to be slidable. The frame portion 14 is configured so that the insertion portion 2 can be inserted from the upper opening 14a. Moreover, when the insertion part 2 is arrange | positioned in the accommodation space 13, the frame part 14 is comprised so that the movement to the front-back direction, the left-right direction, and the downward direction of the said insertion part 2 may be controlled to a predetermined range. In addition, although the holder main body 10 of this example is set as the structure which inserts the insertion part 2 from the upper direction of the accommodation space 13, the 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 accommodation space 13. Thereby, the entrance to the accommodation space 13 is opened, and the insertion part 2 can be easily inserted into the accommodation space 13. An urging member such as a spring is arranged inside the stopper portion 15 so that the stopper portion 15 is automatically restored to the original position after the insertion portion 2 is inserted. The stopper part 15 can restrict | limit the upward movement of the insertion part 2 arrange | positioned in the accommodation space 13 by decompress | restoring to the original position.

  FIG. 3 is a diagram illustrating positions of the insertion portion 2 and the shaft portion 3 in the accommodation space 13 in a state where the insertion portion 2 is inserted into the accommodation space 13 of the holder body 10. As shown in FIG. 3, the diameter D <b> 1 of the insertion portion 2 is smaller than the width W <b> 1 of the accommodation space 13. In this example, the insertion portion 2 has a circular plate shape, but is not limited thereto, and may be an ellipse, a polygon, or the like. Even in this case, the maximum diameter of the insertion portion 2 (passes the axis of the shaft portion 3). The maximum width of the insertion portion 2) is smaller than the width W1 of the accommodation space 13, so that the insertion portion 2 can be rotated in the accommodation space 13. Moreover, the diameter D1 of the insertion part 2 is larger than the width W2 of the front opening 14b located in the front side of the flame | frame part 14, Thereby, the insertion part 2 does not slip out from the said front opening 14b. In addition, although the shape of the insertion part 2 is fundamentally made into the plate shape with constant thickness, it is not restricted to this, It is good also as a three-dimensional shape where thickness is not constant. Further, the shapes of the shaft portion 3 and the base portion 4 are not particularly limited and can be appropriately changed. The base portion 4 is not an essential configuration.

  The insertion part 2 is configured to be able to be inserted into the accommodation space 13 at an arbitrary attachment angle. That is, as shown in FIG. 1, the posture is not limited to an upright posture in which the lower surface 4 b of the base portion 4 faces downward, but is an inverted posture in which the tape measure M and the tool bracket 1 are turned upside down (an posture in which the lower surface 4 b 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 accommodation space 13 from the upper opening 14a of the frame portion 14. In this example, the maximum diameter of the insertion portion 2 (in this example, the diameter D1) is smaller than the width W1 of the accommodation space 13, and the maximum diameter of the shaft portion 3 (in this example, the diameter D2) is the front of the frame portion 14. Since it is smaller than the width W2 of the opening 14b, there is no limitation on the mounting angle of the insertion portion 2, and it can be inserted at an arbitrary mounting angle.

  With such a configuration, the insertion portion 2 can be easily inserted into the accommodation space 13 of the holder 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 body 10, the tool can be easily attached without adjusting the orientation or changing the tape measure M. Therefore, it is possible to prevent a decrease in work efficiency due to the adjustment of the orientation as described above. As described above, according to the tool bracket 1 of the present embodiment, the degree of freedom of the attachment angle with respect to the holder main body 10 can be increased, whereby the attachment of the tool bracket 1 and the tool to the holder main body 10 can be facilitated.

  The tool bracket 1 is configured to be rotatable about the shaft portion 3 with respect to the holder body 10 in a state where the tool bracket 1 is mounted on 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. As described above, the tape measure M can be rotated with respect to the holder main body 10. For example, when the measurement tape is pulled out with the tape measure M attached to the holder main body 10 and measurement is performed, the tape measure M is used. Since it can be rotated to an arbitrary angle, the pulling-out angle of the measuring tape can be changed to a desired angle, and the measurement work becomes easy. For example, when another member or the like collides with the tape measure M attached to the holder main body 10, the impact due to the collision can be reduced by the tape measure M rotating with respect to the holder main body 10. Note that the tool bracket 1 in this example is configured to be movable in the insertion direction (vertical direction in FIG. 3) while being mounted on the holder main body 10. In other words, the insertion portion 2 of the tool bracket 1 can be moved in the vertical direction within a predetermined range in the accommodation space 13, but is not limited thereto, and the vertical movement may be suppressed.

  The tool bracket 1 is preferably configured to automatically return to a predetermined angle after rotating with respect to the holder body 10. According to this, since the posture (attachment 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 to be easily removed, the convenience is improved.

  For example, in a state where the tool bracket 1 fixed to the tape measure M is mounted on the holder main body 10, the position of the support point S supported by the tool bracket 1 on the holder main body 10 is positioned above the center of gravity of the tape measure M. It can be. In this example, the support point S supported by the holder 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. is there. With such a configuration, the tape measure M is supported by the holder body 10 at the support point S above the position of the center of gravity. As a result, the gravity acting on the tape measure M works in a direction that tries to maintain the posture of the tape measure M at a predetermined angle (trying to return to the original position when it rotates), so that the tape measure M is automatically in a fixed posture. It will return to. More specifically, the tool bracket 1 returns to a predetermined posture in which the position of the center of gravity of the tape measure M is arranged directly below the support point S and stops.

  As shown in FIG. 4, the flat surface 3 a is provided on the outer peripheral surface of the shaft portion 3, and the flat surface 3 a is disposed so as to contact the lower edge portion 14 c of the front opening 14 b of the frame portion 14. The rotation around the shaft portion 3 of the tool bracket 1 relative to the holder body 10 can be restricted to some extent. The shaft portion 3 may be provided with a plurality of flat surfaces on the outer peripheral surface thereof. Further, the shaft portion 3 may have a polygonal column shape with a polygonal cross section.

  Further, as a configuration for automatically returning the tool bracket 1 to a predetermined posture, a method using 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. 5A and 5B, elastic pairs 2 a and 2 b that can be elastically deformed are provided on both the left and right sides by forming a pair of left and right notches 2 c in the insertion portion 2. The tool bracket 1 rotates around the shaft portion 3 from the posture shown in FIG. 5A, and the elastic piece 2a comes into contact with the inner side surface 13a of the accommodation space 13 as shown in FIG. When the elastic piece 2a is deformed, the elastic piece 2a automatically returns to a predetermined posture (attachment angle) shown in FIG. When the tool bracket 1 is rotated to the opposite side to FIG. 5B, the elastic piece 2b opposite to the elastic piece 2a elastically deformed in FIG. 5B is elastically deformed. The state shown in FIG. 5A is restored by the restoring force. 5A and 5B, the elastic pieces 2a and 2b provided in the insertion portion 2 are provided, but similar elastic pieces may be provided on the shaft portion 3.

  Further, as a configuration for automatically returning the tool bracket 1 to a predetermined posture, magnets are arranged on the holder body 10 and the tool bracket 1 respectively, and the attractive force or repulsive force between the magnets is used. The posture (attachment angle) of the tool bracket 1 with respect to the holder body 10 may be returned to the expected angle. For example, a magnet is disposed on a part of the outer peripheral surface of the shaft portion 3 of the tool bracket 1, and a magnet is disposed at a position corresponding to the inner edge portion of the frame portion 14 in the holder body 10, and the magnets attract each other. Thereby, it can be set as the structure which returns the bracket 1 for tools to a predetermined attitude | position.

  Here, for example, the rotation of the tape measure M attached to the holder main body 10 can be suppressed by using the rotation suppressing members 20 and 30 shown in FIGS.

  6 includes a main plate portion 21 inserted into the accommodation space 13 of the holder body 10, a support portion 22 protruding forward from the main plate portion 21, and a pair of protrusions protruding downward from the support portion 22. Unit 23. On the upper surface of the main plate portion 21, a concave curved surface 21a is provided. The curved surface 21 a 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 the front view in this example. The rotation restraining member 20 can be attached to the holder body 10 by inserting the main plate portion 21 into the accommodation space 13 from the upper opening 14 a of the frame portion 14 in the holder body 10.

  FIG. 7 shows a state in which the rotation suppressing member 20 is independently attached to the holder main body 10. Further, the insertion portion 2 and the base portion 4 when the insertion portion 2 of the tool bracket 1 is inserted into the accommodation space 13 are shown. It is indicated by a two-dot chain line. In this state, the rotation suppressing member 20 is held in a state where the rotation is suppressed with respect to the holder body 10, 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 relative to the holder body 10 is suppressed.

  Specifically, the main plate portion 21 is held in a state where the rotation is suppressed in the accommodation space 13. 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 in the tool bracket 1. When the lower surface 4b of the base portion 4 indicated by a two-dot chain line in FIG. 7 abuts on the support surface 22a of the tool bracket 1, the rotation of the tool bracket 1 relative to the rotation suppressing member 20 is suppressed. The outer peripheral surface of the insertion part 2 contacts the curved surface 21a. The shape of the support portion 22 is formed so as to be fitted into the front opening 14 b of the frame portion 14 in the holder body 10, and the lower surface 22 b of the support portion 22 abuts on the lower edge portion 14 c of the frame portion 14. Supported. The pair of protrusions 23 are disposed on the front side of the frame portion 14. The rattling of the rotation suppressing member 20 is regulated so that the frame portion 14 is sandwiched between the pair of projecting portions 23 and the main plate portion 21.

  FIG. 8 shows a rotation suppressing member 30 as another example. The rotation suppressing member 30 includes 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 that protrudes from the main body plate portion 31 to one side. The shape of the protruding portion 32 is formed so as to be fitted into the front opening 14 b of the frame portion 14 in the holder main body 10. The protruding 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 body 10 together with the tool bracket 1 in a state of being fitted into the tool bracket 1 fixed to the tape measure M. In addition, the rotation suppression member 30 of this example has a configuration that cannot be attached to the holder body 10 alone.

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