  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a state in which a tool holder 1 as an embodiment of the present invention is mounted on a waist belt 2 as a band-shaped body. FIG. 2 is a perspective view of the tool holder 1 as seen from the back side. The belt-like mounted body is not limited to a horizontal belt-like member extending in a substantially horizontal direction, such as a waist belt 2 wound around a user's waist, and is substantially vertical, for example, a vertical belt portion of a harness-type safety belt. It is also possible to use a vertical belt-like member extending in the direction.

  The tool holder 1 is configured to be detachable from the waist belt 2 and includes a main body 3 and a base 4. The main body 3 and the base 4 are connected via a hinge 5 so as to be rotatable. The main body 3 and the base 4 constitute an annular component that can be deformed between a closed state and an open state. As shown in FIGS. 1 and 2, the closed state is a closed state that forms a ring shape that can surround the waist belt 2 without a gap. As shown in FIGS. 3 and 4, the open state is a state in which a part of the ring shape in the circumferential direction is opened. In this example, the reverse side of the hinge part 5 (the free part of the main body part 3 and the base part 4) On the end side), an interval through which the waist belt 2 can pass is formed between the main body portion 3 and the base portion 4.

  The tool holder 1 includes a captive screw 6 that can be attached to and detached from the main body 3. The captive screw 6 is inserted into a predetermined position of the main body part 3 and the base part 4 in the closed state, and is screwed into at least one of the main body part 3 and the base part 4, whereby the main body part 3 and the base part 4 is suppressed from being opened. In this example, the restraining screw 6 penetrates both the main body 3 and the base 4 and is screwed only to the main body 3. However, only the base 4 or the main body 3 and the base 4 are used. It is good also as a structure screwed to both.

  The main body part 3 has a tool holding part 7 on the front side (the opposite side of the base part 4), and can hold any tool as an object to be held. The tool holding part 7 of this example opens and closes a frame 7a that partitions and forms a holding space S that accommodates and holds a part of the tool, and a tool slidable opening provided in the main body part 3 to the holding space S. And a stopper 7b. When a tool is attached to the tool holding portion 7, a part of the tool (such as a bracket having a shape corresponding to the holding space S) is inserted into the holding space S from above and the tool is stopped by the stopper 7b. Prevents slipping out. When removing the tool from the main body 3, the stopper 7 b is slid obliquely downward to open the insertion port into the holding space S and remove the tool by pulling it upward. Thus, the tool holding part 7 of this example has a function of holding the tool detachably. The tool is not particularly limited, and may be, for example, a hammer, a bar, a ratchet wrench, an electric screwdriver, a tool such as a tape measure, a tool insert or a bag. It is preferable that the tool holding unit 7 can be used by replacing a plurality of types of tools. The tool holding unit 7 may be configured to hold only a specific tool, or may be configured such that the tool is fixed and cannot be removed.

  As shown in FIGS. 2 and 3, the main body portion 3 includes a first engagement portion 8 and a second engagement portion 9 that protrude rearward (tool holding portion 7) in the vicinity of the end portion on the opposite side of the hinge portion 5. Have. The first engagement portion 8 is formed with a through hole 8 a through which the captive screw 6 can pass, and the second engagement portion 9 is formed with a screw hole 9 a. A female screw is provided on the inner surface of the screw hole 9a. In addition, the screw hole 9a does not need to penetrate the 2nd engaging part 9. FIG.

  Here, as shown in FIG. 3, the rear surface of the main body portion 3 (the surface on the base portion 4 side in the closed state) has an uneven portion 16 that exhibits an anti-slip function when contacting the surface of the waist belt 2. Is formed. Thereby, the movement along the extension direction of the waist belt 2 of the tool holder 1 with which the waist belt 2 was mounted | worn can be suppressed. In order to enhance the anti-slip effect, it is preferable that the concavo-convex portions 16 are provided on both the left and right sides of the main body 3 as shown in the illustrated example. In addition, it replaces with the uneven | corrugated | grooved part 16, and members, such as rubber | gum which has a surface with a large frictional resistance, may be attached and the anti-slip | skid function may be improved.

  In addition, a lateral groove 17 is provided on the rear surface of the main body 3 to suppress the displacement of the captive screw 6 inserted through the through hole 8a of the first engagement portion 8. The inner surface shape of the lateral groove 17 corresponds to the side surface shape of the restraining screw 6. Since the lateral groove 17 can prevent the displacement of the restraint screw 6 when it is inserted into the main body 3, the restraint screw 6 can be inserted and screwed smoothly. In particular, when the user attaches the tool holder 1 to the waist belt 2, it is not easy to insert and screw into the main body 3 while checking the angle of the restraining screw 6. By preventing the shift, the restraining screw 6 can be mounted more quickly and accurately.

  As shown in FIG. 5, the restraining screw 6 includes a columnar shaft body 6a, a head portion 6b provided at one end portion of the shaft body 6a, and a male screw portion 6c provided at the other end portion of the shaft body 6a. Have. The captive screw 6 is an enlarged portion 6d that gradually increases in diameter from the shaft body 6a toward the head portion 6b, and an engaged portion provided between the enlarged diameter portion 6d and the head portion 6b. And the plane portion 6e. In this example, the plane portion 6e is provided at four locations at 90 ° intervals in the circumferential direction of the restraining screw 6, and is configured such that the cross section at the position of the plane portion 6e is substantially square (FIG. 9). Further, a step 6f is formed between the enlarged diameter portion 6d and the flat portion 6e. The male screw portion 6 c is screwed into the screw hole 9 a of the second engaging portion 9 provided in the main body portion 3. In this example, the outer diameter of the flat surface portion 6e is made larger than that of the shaft body 6a so as to ensure a large area of the flat surface portion 6e. By ensuring a large area of the flat surface portion 6e, it is possible to enhance the effect of suppressing the loosening of the restraining screw 6 by the loosening suppression mechanism.

  A leaf spring 10 for suppressing loosening of the captive screw 6 screwed to the main body 3 is disposed inside the main body 3. The leaf spring 10 constitutes an elastic part in the loosening suppression mechanism. The elastic portion is not particularly limited as long as it can bias the restraining screw 6 toward the inside in the radial direction.

  As shown in FIG. 6, the leaf spring 10 includes a base portion 10 a that is engaged and held by the main body portion 3, a contact portion 10 b that contacts the restraining screw 6 when the rotation of the restraining screw 6 is suppressed, a base portion 10 a and a contact portion. And a curved deformed portion 10c provided between the portions 10b. The leaf spring 10 can be formed, for example, by bending a metal rectangular plate.

  The base portion 4 has a plate-like configuration that extends in parallel to the main body portion 3 in the closed state and is disposed to face the rear of the main body portion 3. The base portion 4 includes a notch portion 11 extending from the opposite end portion (free end portion) of the hinge portion 5 toward the hinge portion 5 and a pair of left and right plate portions 12 formed by the notch portion 11. , 13. Engaging portions 14 and 15 projecting toward the main body portion 3 side are provided in the vicinity of the respective distal end portions of the pair of left and right plate portions 12 and 13. The engaging portions 14 and 15 are formed with through holes 14a and 15a through which the captive screw 6 passes. In addition, protrusions 12a and 13a projecting from the engaging portions 14 and 15 to the opposite side of the hinge portion 5 are provided at the free end of the pair of plate portions 12 and 13, respectively. The engaging portions 14 and 15 are disposed inside the first engaging portion 8 and the second engaging portion 9 in the closed state, but are outside the first engaging portion 8 and the second engaging portion 9. It is good also as a structure arrange | positioned. Further, the shapes of the engaging portions 14 and 15 are limited as long as the engaging portions 14 and 15 are engaged with the restraining screw 6 screwed to the closed main body portion 3 to suppress the base portion 4 from being opened. Not.

  By providing the notch portion 11 in the base portion 4 as in this embodiment, the tool holder 1 can be attached to the waist belt 2 even on the belt loop 2a as shown in FIG. That is, the base part 4 is inserted inside the waist belt 2 so that the position of the notch part 11 is aligned with the belt loop 2a of the pants and the pair of plate parts 12 and 13 are arranged on both sides of the belt loop 2a. Thus, the main body 3 is disposed on the belt loop 2a. Thereby, the range which can mount | wear with the tool holder 1 in the waist belt 2 becomes large. Further, when the belt loop 2a is sandwiched between the pair of plate portions 12 and 13, as described above, when the tool holder 1 tries to move along the extending direction (longitudinal direction) of the waist belt 2, the plate portion 12, 13 and the belt loop 2a are caught and this movement is suppressed. Therefore, it is possible to prevent the tool holder 1 from being displaced due to, for example, vibration during use.

  Below, the loosening suppression mechanism in the tool holder 1 will be described. The looseness suppression mechanism of this example includes an engaged part (in this example, a flat part 6e and a step 6f) provided on the side surface of the restraining screw 6, and an elastic part (in this example, a leaf spring 10) provided in the main body part 3. Can be configured. FIG. 8 is a cross-sectional view of the tool holder 1 in the front-rear direction passing through the central axis of the captive screw 6. FIG. 9 is a partial cross-sectional view showing an AA cross section of the tool holder 1 in FIG. As shown in FIGS. 8 and 9, the contact portion 10 b of the leaf spring 10 is in contact with the flat surface portion 6 e of the restraining screw 6 to suppress the rotation of the restraining screw 6. That is, when the restraining screw 6 tries to rotate in the loosening direction, the contact portion 10b of the leaf spring 10 is elastically deformed toward the radially outer side of the restraining screw 6 (upward in FIGS. 8 and 9). Due to the restoring force of the elastically deformed leaf spring 10, the contact portion 10 b urges (presses) the flat portion 6 e toward the central axis of the restraining screw 6 (inward in the radial direction), and the restraining screw 6 rotates. It gives resistance to it. In this way, the leaf spring 10 imparts a resistance force to the rotation of the restraining screw 6 in the loosening direction, so that the restraining screw 6 can be prevented from loosening due to vibration or the like during use of the tool holder 1. In addition, in this example, since the several plane part 6e is provided in the circumferential direction, even if the contact part 10b of the leaf | plate spring 10 gets over one plane part 6e by rotation of the restraining screw 6, it will be circumferential. When the contact portion 10b comes into contact with the next adjacent flat portion 6e, the loosening suppression effect is continuously exhibited. As a result, the effect of preventing the tool holder 1 from dropping off can be enhanced. If the restraining screw 6 continues to rotate in the loosening direction with a force larger than the resistance force of the leaf spring 10, the restraining screw 6 can be unscrewed. In the unscrewing process of the restraining screw 6, the leaf spring is applied to the flat portion 6e. When the 10 contact portions 10b do not come into contact with each other, the loosening suppression mechanism is automatically released.

  In addition, in this example, although the plane part 6e is provided as an engaged part so that a cross section may become a square, if it is a shape which produces resistance when the captive screw 6 tries to rotate in the loosening direction, The shape of the engaged portion is not particularly limited. For example, flat portions having different lengths may be provided so that the cross section is rectangular, or a shape in which the cross section is a polygon other than a rectangle or an ellipse may be used. Or it is good also as a shape where an unevenness | corrugation is repeated in the circumferential direction. In addition, when the plane part from which length differs so that a cross section becomes a rectangle, when an elastic part contacts the plane part which comprises a long side, the loosening suppression effect becomes large. In addition, it is preferable to provide four plane parts 6e so that a cross section may become a square, ie, the circumferential direction of the restraining screw 6. FIG. According to this, compared with the case where a cross section is a polygon more than a pentagon, a loosening suppression effect can be ensured highly and formation of plane part 6e also becomes easy.

  Further, the leaf spring 10 constituting the elastic part in the loosening suppression mechanism may be another spring member such as a coil spring or a pine needle spring, or may be an elastic member such as rubber or elastomer. Any elastic portion may be used as long as it generates resistance when the captive screw 6 rotates in the loosening direction due to a restoring force when elastically deforming. Moreover, you may adjust the loosening suppression effect by changing the shape of the contact part 10b of the leaf | plate spring 10, and making a contact area with the plane part 6e large or small.

  Moreover, in this example, since the level | step difference 6f is provided in the side surface of the restraint screw 6, resistance arises also when the leaf | plate spring 10 gets over the level | step difference 6f. Thereby, the effect which suppresses the loosening of the captive screw 6 can be heightened. As described above, the step 6f functions as an engaged portion of the loosening suppression mechanism. Therefore, only the step 6f may be provided without providing the flat portion 6e.

  Below, the attachment / detachment method of the tool holder 1 with respect to the waist belt 2 is demonstrated. When the tool holder 1 is attached to the waist belt 2, as shown in FIG. 4, the captive screws 6 are removed and the free ends (protrusions 12 a and 13 a) of the base portion 4 opened are placed inside the waist belt 2. Insert from above. And it inserts until the engaging parts 14 and 15 are located below the lower end of the waist belt 2, and the main-body part 3 and the base part 4 are closed. When the main body part 3 and the base part 4 are closed until the closed state, the first engaging part 8 and the second engaging part 9 of the main body part 3 overlap with the engaging parts 14 and 15 of the base part 4 in a side view. Are arranged as follows. Thereby, the circumference | surroundings of the waist belt 2 by the annular shape formed of the main-body part 3 and the base part 4 can be surrounded without a clearance gap in the circumferential direction. In the closed state, the captive screw 6 is inserted from the through hole 8a, passed through the through hole 14a and the through hole 15a, and the male screw portion 6c is screwed into the screw hole 9a. The captive screw 6 attached to the main body 3 suppresses the movement of the base 4 in the open state. Thereby, the attachment of the tool holder 1 to the waist belt 2 is completed. In this state, unless the captive screw 6 is removed, the closed state in which the periphery of the waist belt 2 is surrounded by the main body portion 3 and the base portion 4 without any gap is maintained. Further, in the process of screwing the captive screw 6 to the main body portion 3, a resistance force is applied to the rotation of the captive screw 6 when the contact portion 10 b of the leaf spring 10 contacts the flat surface portion 6 e. That is, in this embodiment, the loosening suppression mechanism is configured to function automatically only by attaching the restraining screw 6. That is, since a special operation for causing the loosening suppression mechanism to function is unnecessary, the attachment operation of the tool holder 1 is easy.

  When removing the tool holder 1 from the waist belt 2, the captive screw 6 is unscrewed and removed, the main body portion 3 is opened with the hinge portion 5 as a fulcrum, and the base portion 4 is pulled upward to lift the waist belt 2. Removal is completed by pulling out from the inside. In the present embodiment, in the process of unscrewing the captive screw 6, the contact portion 10b of the leaf spring 10 is not in contact with the flat surface portion 6e, and the looseness suppression function by the looseness suppression mechanism is automatically released. . That is, since the special operation for canceling the function of the loosening suppression mechanism is unnecessary, the tool holder 1 can be easily detached.

  According to the tool holder 1 of the present embodiment having the above-described configuration, it is possible to more reliably prevent the tool holder 1 from dropping from the waist belt 2 that is a belt-like mounted body, thereby improving safety. Become. Moreover, the attachment / detachment operation of the tool holder 1 with respect to the waist belt 2 is also easy.

  In the present embodiment, in the state where the tool holder 1 is attached to the waist belt 2, the leaf spring 10 and the flat portion 6e of the restraining screw 6 constituting the loosening suppression mechanism are not exposed to the outside. The loosening suppression mechanism is not easily damaged, and performance degradation due to intrusion of dust or the like hardly occurs. Further, since the leaf spring 10 is built in the main body 3, there is little possibility that the leaf spring 10 is dropped or lost.

  In the process of attaching the tool holder 1 to the waist belt 2, when the captive screw 6 is inserted, the main body portion 3 and the base portion 4 must be maintained in a closed state, but in this embodiment, the base portion This operation is facilitated by providing protrusions 12a and 13a at the free ends of the four. That is, in the closed state, the protrusions 12 a and 13 a protrude downward from the first engagement portion 8 and the second engagement portion 9 of the main body portion 3, so that the protrusion portions 12 a and 13 a and the main body portion 3. Can be sandwiched with fingers from the front and rear sides. Thus, since the main body 3 and the base 4 can be sandwiched and supported from both front and rear sides, the closed state can be easily maintained and the insertion operation of the restraining screw 6 is facilitated.

  Below, the modification of a loosening suppression mechanism is demonstrated. 10A to 10C show an example in which a C-ring 22 whose diameter is elastically contracted is disposed in a groove 21 formed on the side surface of the restraining screw 6. In addition, description is abbreviate | omitted about the structure similar to previous embodiment.

  The groove 21 is an annular groove extending over the entire circumference along the circumferential direction of the restraining screw 6 and has a depth that allows the C-ring 22 with a reduced diameter to enter. The C-ring 22 is a substantially C-shaped metal or resin member in which a part of the ring shape in the circumferential direction is intermittent, and has a circular cross section as shown. The cross-sectional shape of the C-ring 22 is not limited to a circle, and may be a polygon, for example. However, from the viewpoint of smoothly reducing the diameter of the C-ring 22 when passing through the through hole 8a, A circular shape is preferred.

  In the normal state of the C ring 22 shown in FIGS. 10A and 10C, the outer diameter of the C ring 22 is larger than the inner diameter of the through hole 8 a of the first engagement portion 8 of the main body 3. In the reduced diameter state shown in FIG. 10B, the outer diameter of the C ring 22 is equal to or smaller than the inner diameter of the through hole 8a. Since the inner diameter in the normal state shown in FIGS. 10A and 10C is smaller than the outer diameter of the shaft main body 6a, the C ring 22 is held by the restraining screw 6 without coming out of the groove 21.

  When attaching the captive screw 6 to the main body portion 3 and the base portion 4 in the closed state, the C-ring 22 penetrates by rotating the captive screw 6 in the tightening direction (screwing the screw portion). The diameter of the hole 8a is reduced while being guided by the inclined surface 8b of the hole 8a, and the inside of the through hole 8a is press-fitted. When the mounting of the restraining screw 6 is completed, the C-ring 22 expands to its original state by its restoring force, as shown in FIG. 10C. Thereby, when the restraining screw 6 tries to move in the loosening direction, the C ring 22 comes into contact with the peripheral edge portion of the through hole 8a and imparts a resistance force, so that loosening of the restraining screw 6 can be suppressed.

  When removing the restraining screw 6 from the main body 3, the restraining screw 6 can be easily removed by rotating the restraining screw 6 in the loosening direction with a force exceeding the resistance force. At that time, the C-ring 22 is reduced in diameter while being guided by the inclined surface 8c, and passes through the inside of the through hole 8a. Further, in the process of removing the restraining screw 6, the loosening suppression function of the loosening suppression mechanism is automatically released, so that the operation is not complicated.

  Here, while the C ring 22 is in contact with the first engagement portion 8 and resistance is generated in the movement of the restraining screw 6, the male thread portion 6 c of the restraining screw 6 is always in contact with the screw hole 9 a of the main body portion 3. It is preferable to be screwed into the female screw portion. According to this, since the C-ring 22 can be press-fitted or passed through the through-hole 8a only by rotating the restraining screw 6, no large force is required, and the restraining screw 6 can be easily attached and detached. It can be performed.

  Instead of the C ring 22, an annular O ring formed of an elastic material such as rubber may be disposed in the groove 21. In this case, the O-ring is allowed to pass through the through hole 8a by being elastically deformed and crushed. When the O-ring passes through the through-hole 8a, a resistance force is applied to the restraining screw 6, so that it can function as a loosening suppression mechanism for the restraining screw 6.

  11A and 11B show another modification of the loosening suppression mechanism. In this example, a small diameter portion 23 is provided in the shaft main body 6 a of the restraining screw 6, and the small diameter portion 23 is formed in a dharma hole 25 formed in the shaft portion 24 a of the release button 24 provided in the main body portion 3. It is set as the structure engaged. FIG. 11A is a cross-sectional view passing through the central axis of the captive screw 6, and FIG. 11B is a cross-sectional view taken along the line BB of FIG. 11A. The small-diameter portion 23 is a portion that is formed in a part of the shaft body 6a in the axial direction and has a smaller diameter than other portions of the shaft body 6a.

  The release button 24 is urged upward by a coil spring 26 built in the main body 3. The inner diameter of the small diameter region 25a of the Dharma hole 25 is larger than the outer diameter of the small diameter portion 23 and smaller than the outer diameter of the shaft body 6a. Moreover, the internal diameter of the large diameter area | region 25b of the dharma hole 25 is larger than the outer diameter of the shaft main body 6a.

  As shown in FIGS. 11A and 11B, in a state where the restraining screw 6 is screwed to the main body portion 3, the small diameter portion 23 of the restraining screw 6 is fitted into the small diameter region 25 a of the dharma hole 25, and the axial movement of the restraining screw 6 is performed. Is suppressed. Thereby, loosening of the captive screw 6 is suppressed.

  When removing the restraining screw 6 from the main body 3, the restraining screw 6 is disposed in the large-diameter region 25 b of the dharma hole 25 by pressing down the pressing portion 24 b of the release button 24 exposed to the outside of the main body 3. Since the restriction is released in the axial direction of the restraining screw 6, the restraining screw 6 can be removed.

  FIG. 12 shows another modification of the loosening suppression mechanism. In this example, the release button 24 is configured to be swingable with a shaft portion 27 built in the main body 3 as a fulcrum. The release button 24 includes a pressing portion 24b biased upward by a coil spring 26, an inclined portion 24c connected to the pressing portion 24b and disposed on the opposite side across the shaft portion 27, and an inclination portion 24c. And an engaging portion 24d at the tip. The engagement portion 24d is engaged with the step 23a formed by the small diameter portion 23 of the restraining screw 6, whereby the axial movement of the restraining screw 6 is suppressed. Thereby, loosening of the captive screw 6 is suppressed.

  When removing the restraining screw 6 from the main body 3, the restraining screw 6 is unscrewed and pulled out while pressing the pressing portion 24 b of the release button 24. When the pressing portion 24b is pushed down, the inclined portion 24c swings with the shaft portion 27 as a fulcrum, and the engaging portion 24d moves upward, so that the engagement between the engaging portion 24d and the step 23a is released and restrained. The screw 6 can be removed.

  In place of the normal restraining screw 6 extending in a straight line, the loosening suppression mechanism may be configured by using the bending or bending eccentric screws 31 and 32 as shown in FIGS. 13A and 13B. . In this case, the through holes 8a of the main body 3 and the through holes 14a and 15a of the base 4 are long holes except for the screw holes 9a of the main body 3 that are screwed into the male screw 6c. As described above, when the eccentric screws 31 and 32 that are partially deformed or eccentric are used, the screws are difficult to rotate, so that loosening of the mounted screws can be suppressed.

  Here, you may comprise the cyclic | annular structure part of this invention by the main-body part 41 and the insertion member 42 as shown to FIG. FIG. 14 is a perspective view showing a state in which a tool holder 40 according to another embodiment of the present invention is attached to the waist belt 2, and FIG. 15 is a rear view of the tool holder 40.

  In the present example, the main body 41 has an upper protrusion 43 and a lower protrusion 44 that protrude rearward. A first insertion hole 43 a is formed in the upper protrusion 43, and a second insertion hole 44 a is formed in the lower protrusion 44.

  14 and 15, the insertion member 42 is inserted into the first insertion hole 43a and the second insertion hole 44a and is held by the main body portion 3, whereby the annular component is closed. 14 and 15, the state in which the insertion member 42 is pulled out from at least the second insertion hole 44a is an open state, and the waist belt 2 is connected to the main body portion through the open portion of the ring shape. 41 and the insertion member 42 can be arranged. By pressing the main body 41 from the outside of the waist belt 2 and inserting the insertion member 42 that has passed through the first insertion hole 43a into the inside of the waist belt 2 and then into the second insertion hole 44a, the tool can be easily used. The annular component of the holder 40 can be attached to the waist belt 2.

  In this example, the captive screw 6 is inserted into the lower projecting portion 44 of the main body 41 in the closed state and is screwed. When the captive screw 6 screwed to the main body 41 penetrates the insertion member 42 or engages with the insertion member 42, the insertion member 42 is prevented from coming out of the second insertion hole 44a.

  Also in the tool holder 40 of this example, for example, the leaf spring 10 is incorporated in the lower protrusion 44 of the main body 41 and is brought into contact with the flat surface 6e provided on the side surface of the restraining screw 6, A loosening suppression mechanism can be provided. In addition, the tool holder 40 of this example may be provided with any of the above-described loosening suppression mechanisms.

  While the present invention has been described based on the illustrated examples, the present invention is not limited to the above-described embodiment, and can be appropriately changed within the scope of the claims. The tool holder 1 may be mounted by inserting the tip of the waist belt 2 from the side of the closed tool holders 1 and 40 into the inside of the ring shape. Similarly, when removing the tool holders 1 and 40 from the waist belt 2, the waist belt 2 may be pulled out sideways while the tool holders 1 and 40 are in a closed state.
