Formed on the bottom piece A bottom floor portion provided with a protrusion that engages with the formed hole, and at least one of the opposing surfaces of the vertical wall portion, the distance between the tip portions is narrower than the width of the frame-shaped guard. A movable protrusion is provided that is constantly urged in a protruding direction and is pushed into the vertical wall portion by the frame-shaped guard and grips the frame-shaped guard from the side in a protruding state. To do.

According to the present invention, the operation for preventing the hose nozzle from falling off is integrated with the mounting operation of the hose nozzle on the hose nozzle holder.
That is, when the hose nozzle is attached to the hose nozzle holder according to the present invention, the operator holds the handle portion of the hose nozzle and first inserts the oil supply pipe into the cylindrical cover portion. Subsequently, with the hose nozzle in a standing posture, the frame guard is pushed between the vertical wall portions of the mounting table. At this time, the cylindrical cover portion rotates with respect to the main body portion following the change in the posture of the hose nozzle, covers the oil supply pipe of the hose nozzle from above, and restricts the movement of the oil supply pipe of the hose nozzle. Further, by pushing the frame guard between the vertical walls of the mounting table, the movable protrusions provided on at least one of the opposing surfaces of the vertical wall grip the frame guard from the side, and grip the hose nozzle. Limit the movement of parts.
In this state, further, the hole formed in the lower piece of the frame guard when the hose nozzle is in the standing posture is engaged with the protrusion standing on the bottom floor portion of the mounting base of the main body portion, and attached. By completing the work, the movement of the hose nozzle is reliably regulated by the hose nozzle holder, and the hose nozzle is prevented from dropping off.

In the present invention, the movable protrusion is preferably a triangular door spring or a roller-shaped guide.
According to the present invention, the distance between the opposing surfaces of the vertical wall portion of the mounting table of the hose nozzle holder and the tip of the triangular door spring or roller-shaped guide (commonly referred to as “peco lock”) is It always protrudes in the protruding direction so that it is narrower than the width of the frame guard, and the triangular door spring or roller guide is pushed into the vertical wall by the frame guard, and the frame guard is held from both the left and right sides in the protruding state. As a result, the movement of the hose nozzle is reliably regulated by the hose nozzle holder, and the hose nozzle is prevented from dropping off.

Further, in the present invention, the movable protrusion of the vertical wall portion has an asymmetric shape in the attaching / detaching direction of the frame-shaped guard, and only the surface that contacts when the frame-shaped guard is pushed between the vertical wall portions, It is composed of a curved surface or an inclined surface that facilitates displacement of the movable protrusion to the vertical wall portion, and the main body portion is provided with an operation lever for pulling the movable protrusion into the vertical wall portion. desirable.
According to this configuration, by pushing the frame-shaped guard between the vertical wall portions of the mounting table, the frame-shaped guard comes into contact with a curved surface or an inclined surface that promotes displacement of the movable protrusion to the vertical wall portion, and the vertical wall portion The movable protrusion provided on the opposite surface is pushed away in the left-right direction by the frame guard. When the frame-shaped guard passes through the movable protrusion, the movable protrusion again protrudes from the facing surface of the vertical wall portion, grips the frame-shaped guard from the side, and restricts the movement of the grip portion of the hose nozzle. On the other hand, the movable projection of the vertical wall portion is asymmetrical in the attaching / detaching direction of the frame-shaped guard, and the surface that comes into contact when the frame-shaped guard is pulled out from between the vertical wall portions does not displace the movable projection to the vertical wall portion. It is not composed of a urging curved surface or inclined surface. Therefore, the asymmetric movable protrusion functions as a retaining latch for the frame-shaped guard, and a sufficient holding force for holding the frame-shaped guard is secured by the asymmetric movable protrusion. On the other hand, by pulling the movable projection into the vertical wall portion by the operation lever, the retaining of the frame-shaped guard by the movable projection is released, and the frame-shaped guard can be pulled out from the vertical wall portion.

  Moreover, the hose nozzle holder according to the present invention for solving the above-mentioned problems is a joint with an oil supply hose, a flow rate adjusting valve, a trigger for operating the flow rate adjusting valve, and a frame-like guard surrounding the trigger. A hose nozzle holder that holds the hose nozzle in a standing posture with the oil supply pipe facing upward, and a hose nozzle that includes a oil supply pipe that protrudes toward the distal end side of the grip part. And a cylindrical cover portion that covers the oil supply pipe. A mounting base for the frame-shaped guard is fixed below the main body portion, and the cylindrical cover portion is disposed above the main body portion. The base end portion is pivotally mounted so that the mounting table includes the vertical wall portion facing the frame-like guard so as to sandwich the frame-shaped guard from both the left and right sides, and the frame when the hose nozzle is in a standing posture. On the bottom piece And a bottom floor portion provided with a protrusion that engages with the formed hole, and a notch is formed in at least one of the vertical wall portions, and the notch is formed from the outside of the vertical wall portion through the notches. A protrusion that enters the space sandwiched between the vertical wall portions and grips the frame guard from the side is pivotally attached to the main body portion.

The mounting operation of the hose nozzle in the present invention is as follows. The worker holds the grip portion of the hose nozzle, and first inserts the oil supply pipe into the cylindrical cover portion. Subsequently, with the hose nozzle in a standing posture, the frame guard is pushed between the vertical wall portions of the mounting table. At this time, the cylindrical cover portion rotates with respect to the main body portion following the change in the posture of the hose nozzle, covers the oil supply pipe of the hose nozzle from above, and restricts the movement of the oil supply pipe of the hose nozzle. Further, the frame guard is pushed between the vertical walls of the mounting table.
In this state, further, by engaging the hole formed in the lower piece of the frame-shaped guard when the hose nozzle is in the standing posture, with the protrusion erected on the bottom floor portion of the mounting table of the main body, The movement of the hose nozzle is regulated by the hose nozzle holder. Thereafter, from the outside of the vertical wall portion, a protrusion is inserted into the space sandwiched by the vertical wall portion through a notch formed in at least one of the vertical wall portions, and the frame-shaped guard is laterally moved by the protrusion. By gripping (blocking the upper part of the lower piece of the frame-shaped guard), the hose nozzle holder is prevented from being lifted from the mounting table, and the hose nozzle is reliably prevented from falling off.

In the present invention, the protrusion protrudes from a lever that is pivotally attached to the main body, and the fulcrum of the lever rises from the mounting table and comes into contact with the protrusion. It is desirable that the lever is provided at a position where a force for pulling in the space between the vertical wall portions is applied to the lever.
According to the present invention, since the lever is pivotally attached to the main body portion, the lever is always integrated with the main body portion, and when the hose nozzle is removed from the hose nozzle holder, additional work such as storing the lever is not performed. It becomes unnecessary. In addition, the hose nozzle can be fixed to the hose nozzle holder only by rotating the lever around the fulcrum. Moreover, when the hose nozzle is lifted from the mounting table and the frame guard abuts the protrusion, a force is applied to the lever to pull the protrusion in the space between the vertical walls, and the protrusion more reliably holds the frame guard. As a result, the hose nozzle is reliably prevented from falling off.

In the present invention, the lever may be provided with a stopper that comes into contact with the vertical wall portion in a state where the protrusion protrudes into a space sandwiched between the vertical wall portions through a notch. desirable.
According to the present invention, since the stopper of the lever comes into contact with the vertical wall portion of the mounting table, the hose nozzle is lifted from the mounting table, and the frame-shaped guard is in contact with the protrusion, so that the protrusion is sandwiched between the vertical wall portions. The lever does not further rotate around the fulcrum in a state where a force for pulling in the space direction is applied to the lever, and the frame guard guarded state by the protrusion is reliably maintained.

In the present invention, it is desirable that the main body portion also serves as an attachment member for the tank truck.

  The best mode for carrying out the present invention will be described below with reference to the accompanying drawings. In addition, the same part as a prior art, or a part corresponding to it is shown with the same code | symbol, and detailed description is abbreviate | omitted.

  As shown in FIGS. 1 and 2, the hole nozzle holder 46 according to the first embodiment of the present invention holds the hose nozzle 10 in a standing posture with the oil supply pipe 22 facing upward. The hose nozzle 10 is an existing hose nozzle, and includes a joint 12 with a fueling hose, a flow rate adjusting valve 14, a trigger 16 for operating the flow rate adjusting valve 14, and a frame-shaped guard 18 surrounding the trigger 16. A portion 20 and an oil supply pipe 22 that protrudes toward the distal end side of the grip portion 20 are provided.

  The hole nozzle holder 46 includes a main body portion 26 that holds the grip portion 20 of the hose nozzle 10 and a cylindrical cover portion 28 that covers the oil supply pipe. A mounting table 30 for the frame-shaped guard 18 is provided below the main body portion 26. The base end portion of the cylindrical cover portion 28 is pivotally attached to the upper portion of the main body portion 26 by a pivot 32 so as to be swingable. The cylindrical cover portion 28 is inclined so that the tip end portion is lowered downward by its own weight. The main body portion 26 is formed by bending a plate material into a channel shape, and also serves as an attachment member for the tank truck.

  The mounting table 30 engages with a vertical wall portion 48 that faces the frame-shaped guard 18 so as to sandwich the frame-shaped guard 18 from both left and right sides, and a hole formed in a lower piece of the frame-shaped guard 18 when the hose nozzle 10 is in a standing posture. And a bottom floor portion 50 on which a projection 36 is erected. In the illustrated example, a U-shaped presser plate 34 sandwiching the frame guard 18 from both the left and right sides is fixed to the bottom floor 50 as in the conventional example (FIGS. 7 and 8). The vertical wall portion 48 has a box shape for storing a movable projection 52 described later, and is fixed to both sides of the main body portion 26.

A movable protrusion 52 is provided on each facing surface of the vertical wall portion 48. The movable protrusion 52 is constantly urged in the protruding direction so that the distance x between the tip portions is narrower than the width of the frame-shaped guard 18 of the hose nozzle 10 and is pushed into the vertical wall 48 by the frame-shaped guard 18. Thus, the frame-shaped guard 18 is gripped from both the left and right sides in the protruding state. The movable protrusion 52 is disposed at a distance from the bottom surface 26 a of the channel-shaped main body portion 26, and the frame-shaped guard 18 of the hose nozzle 10 pushes the movable protrusion 52 into the vertical wall portion 48 to move the movable protrusion 52. After passing through 52, the movable projection 52 projects between the frame-shaped guard 18 and the trigger 16, so that the frame-shaped guard 18 can be gripped from both the left and right sides.
The movable protrusion 52 has a structure in which a projecting element such as a semi-cylindrical shape, a triangular prism shape, or a roller shape is constantly biased in a protruding direction by a spring. In the field of building materials, a triangular door spring, a roller-shaped guide (peco What is called a lock or the like can be used as it is.

Now, according to the first embodiment of the present invention having the above-described configuration, the operation for preventing the hose nozzle 10 from falling off is integrated with the mounting operation of the hose nozzle 10 on the hose nozzle holder 46. It becomes.
That is, when attaching the hose nozzle 10 to the hose nozzle holder 46, the operator holds the grip portion 20 of the hose nozzle 10, and first, the cylindrical cover is inclined so as to lower the tip portion downward by its own weight. The oil supply pipe 22 is inserted into the portion 28. Subsequently, the hose nozzle 10 is set in a standing posture, and the frame-shaped guard 18 is pushed between the vertical wall portions 48 of the mounting table 30. At this time, the cylindrical cover part 28 rotates with respect to the main body part 26 following the change in the posture of the hose nozzle 22 to cover the oil supply pipe 22 of the hose nozzle 10 from above and the movement of the oil supply pipe 22 of the hose nozzle 10. Limit. Further, by pushing the frame-shaped guard 18 between the vertical wall portions 48 of the mounting table 30, the movable protrusions 52 provided on the opposing surfaces of the vertical wall portion 48 grip the frame-shaped guard 18 from both the left and right sides. The movement of the grip part 20 of the hose nozzle 10 is limited.

In this state, when the hose nozzle 10 is in the standing posture, the hole 36 formed in the lower piece of the frame guard 18 is provided with a protrusion 36 erected on the bottom floor 50 of the mounting table 30 of the main body 26. The movement of the hose nozzle 10 is reliably regulated by the hose nozzle holder 46, and the hose nozzle 10 is also prevented from dropping off.
Further, when removing the hose nozzle 10 from the hole nozzle holder 46, the frame-shaped guard 18 of the hose nozzle 10 moves the movable protrusion 52 to the vertical wall portion 48 by pulling the grip portion 20 of the hose nozzle 10 toward you. Since it can push and pass the movable protrusion 52, the hose nozzle 10 can be removed smoothly, without performing special release operation.

  Moreover, since the movable protrusion 52 is a triangular door spring or a roller-shaped guide, the front end portion of the triangular door spring or the roller-shaped guide is formed from each facing surface of the vertical wall portion 48 of the mounting table 30 of the hose nozzle holder 46. The gap x always protrudes in the protruding direction so as to be narrower than the width of the frame-shaped guard 18, and the triangular door spring or roller-shaped guide is pushed into the vertical wall portion 48 by the frame-shaped guard 18, and the frame is in the protruding state. By holding the shape guard 18 from both the left and right sides, the movement of the hose nozzle 10 is reliably regulated by the hose nozzle holder 46, and the hose nozzle 10 is also prevented from dropping off.

In addition, since the main body portion 26 also serves as an attachment member for the tank truck, the movement of the hose nozzle 10 of the oil supply hose of the tank truck is ensured by the hose nozzle holder 46 by attaching the main body section 26 of the hose nozzle holder 46 to the tank truck. The hose nozzle 10 is surely prevented from falling off.
The hose nozzle holder 46 is not limited to the case where it is mounted on a tank lorry, and can be securely held by attaching the hose nozzle of the tank by attaching it to a fixed tank.

FIG. 3 shows only a portion of the vertical wall portion 48 and the movable protrusion 52 of the hose nozzle holder as an application example of the first embodiment of the present invention shown in FIGS. In such an application example, the movable protrusion 52 is provided only on one vertical wall portion 48. Further, the movable protrusion 52 is asymmetric in the mounting direction A of the frame guard 18 and the drawing direction B. Specifically, only the surface 52a that comes into contact when the frame-shaped guard 18 is pushed between the vertical wall portions 48 is composed of a curved surface or an inclined surface that promotes displacement of the movable protrusion 52 to the vertical wall portion 48. The surface 52b that comes into contact when the frame-shaped guard 18 is pulled out from between the vertical wall portions 48 is a plane that is orthogonal to the pulling direction B. Further, an operation lever 54 for pulling the movable protrusion 52 into the vertical wall 48 is provided on the main body (the vertical wall 48 in the illustrated example) of the hose nozzle holder. Inside the vertical wall portion 48, a drive mechanism for pulling the movable protrusion 52 into the vertical wall portion 48 by rotating the operation lever 54 in the direction of arrow C is incorporated. The operation lever 54 is not limited to the illustrated example. For example, the movable protrusion 52 may be pulled into the vertical wall portion 48 in conjunction with the pressing operation of the push button.
A cushion material 56 such as a rubber block is fixed to the other vertical wall portion 48 that does not include the movable protrusion 52 in place of the movable protrusion 52. Then, the distance between the projecting movable protrusion 52 and the tip of the cushion material 56 is X (FIG. 2). When the movable protrusion 52 is drawn into the vertical wall 48, the distance between the tips is the frame. It becomes wider than the width of the guard 18.

According to this configuration, by pushing the frame-shaped guard 18 between the vertical wall portions 48 of the mounting table, the frame-shaped guard 18 comes into contact with the curved surface or the inclined surface 52a that promotes the displacement of the movable protrusion 52 to the vertical wall portion. The movable protrusion 52 provided on the opposite surface of the vertical wall portion 48 is pushed away in the left-right direction by the frame guard 18. When the frame-shaped guard 18 passes through the movable protrusion 52, the movable protrusion 52 protrudes again from the facing surface of the vertical wall portion 48, grips the frame-shaped guard 18 from the side, and the cushion material 56 is the side surface of the frame-shaped guard 18. The movement of the grip portion of the hose nozzle is restricted in combination with the contact with the hose nozzle. On the other hand, the movable protrusion 52 of the vertical wall portion 48 has an asymmetric shape in the attaching and detaching directions A and B of the frame guard, and the surface 52b that comes into contact when the frame guard 18 is pulled out from between the vertical wall portions 48 is the frame guard. 18 is a plane perpendicular to the drawing direction B, and is not formed of a curved surface or an inclined surface that facilitates displacement of the movable protrusion 52 to the vertical wall portion 48 like the surface 52a. Therefore, the asymmetric movable protrusion 52 functions as a latch for preventing the frame-shaped guard 18 from being detached, and the asymmetric movable protrusion 52 ensures a sufficient holding force for holding the frame-shaped guard 18. On the other hand, by pulling the movable projection 52 into the vertical wall portion 48 by the operation lever 54, the retaining of the frame-shaped guard 18 by the movable projection 52 is released, and the frame-shaped guard 18 can be pulled out from the vertical wall portion 48. Become.
In addition, detailed description of the same effects as those in the example of FIGS. 1 and 2 is omitted.

Next, a second embodiment of the present invention will be described with reference to FIGS. Note that the same or corresponding portions as those in the first embodiment of the present invention are denoted by the same reference numerals, and detailed description thereof is omitted.
In the hose nozzle holder 58 according to the second embodiment of the present invention, the U-shaped presser plate 34 in the example of FIGS. 1 and 2 functions as the mounting table 30. The U-shaped presser plate 34 is formed on a vertical wall portion 34a that faces the frame-shaped guard 18 so as to sandwich the frame-shaped guard 18 from both left and right sides, and a lower piece 18a of the frame-shaped guard 18 when the hose nozzle 10 is in a standing posture. The bottom floor 50 is provided with a projection 36 that is engaged with the hole 18b (FIG. 5). And the notch 34c (FIG. 6) is formed in one side of the vertical wall part 34a.

  A lever 60 is pivotally attached to the main body 26. In the illustrated example, the lever 60 is formed by punching a steel plate, and a projection 72 and a stopper 74 described later are integrally formed. The lever 60 is fixed with a pin 62 having a threaded groove at the tip. The pin 62 is inserted through a boss 64 fixed to the side surface of the channel-shaped main body 26 (by welding or the like). Then, a washer 66 and a disc spring 68 are inserted into the thread groove at the tip of the pin 62 that passes through the boss 64, and the nut 70 is tightened, whereby the lever 60 is rotatably fixed to the main body 26. Moreover, by adjusting the tightening force of the nut 70, the amount of elastic deformation of the disc spring 68 changes, the frictional resistance force between the lever 60 and the boss 64 changes, and even if the lever 60 is released, The lever 60 can be set to be fixed at an arbitrary position.

  The protrusion 72 projecting from the lever 60 projects from the outside of the vertical wall portion 34a into the space sandwiched between the vertical wall portions 34a through the notches 34c and grips the frame-shaped guard 18 from the side. . The stopper 74 is a portion that contacts the vertical wall portion 34a in a state where the protrusion 72 passes through the notch 34c formed on one side of the vertical wall portion 34a. Then, from the state in which the stopper 74 of the lever 60 is in contact with the vertical wall portion 34a, the protrusion 72 is formed into the vertical wall by rotating the lever 60 about the pin 62 by an angle θ (θ = 20 ° in the illustrated example). The portion 34a is completely removed outward from the notch 34c. As will be described later, the fulcrum (pin 62) of the lever 60 is lifted from the mounting table 30 and comes into contact with the protrusion 72, so that the protrusion 72 is sandwiched between the vertical wall portions 34a. It is provided at a position where a pulling force is applied to the lever 60. In the illustrated example, the stopper 74 is formed in an edge shape that abuts in parallel with the vertical wall portion 34a, and the protrusion 72 has a frame shape in a state in which the stopper 74 abuts on the vertical wall portion 34a. It is formed in a shape that covers the upper part of the lower piece 18 a of the guard 18. The lever 60, the protrusion 72, and the stopper 74 may be made of a resin plate, or may be formed by combining, for example, bar materials.

  The mounting operation of the hose nozzle 10 of the hose nozzle holder 58 according to the second embodiment of the present invention is as follows. An operator holds the grip portion 20 of the hose nozzle 10 and first inserts the oil supply pipe 22 into the cylindrical cover portion 28. Subsequently, with the hose nozzle 10 in a standing posture, the frame guard 18 is pushed between the vertical wall portions 34a of the mounting table 30 (the U-shaped presser plate 34). At this time, the cylindrical cover portion 28 follows the change in the posture of the hose nozzle 10 and rotates with respect to the main body portion 26 to cover the oil supply pipe 22 of the hose nozzle 10 from above and the movement of the oil supply pipe 22 of the hose nozzle 10. Limit. Further, the frame guard 18 is pushed between the vertical wall portions 34 a of the presser plate 34.

  In this state, the hole 18b formed in the lower piece 18a of the frame guard 18 when the hose nozzle 10 is in the standing posture is further provided on the bottom floor 50 of the holding plate 34 of the main body 26. By engaging with 36, the movement of the hose nozzle 10 is regulated by the hose nozzle holder 58. Thereafter, the protrusion 72 is inserted into the space sandwiched between the vertical wall portions 34a from the outside of the vertical wall portion 34a through the notches 34c formed in at least one of the vertical wall portions 34a. By gripping the guard 18 from the side (blocking the upper part of the lower piece 18a of the frame-shaped guard 18), the hose nozzle 10 is prevented from lifting from the presser plate 34, and the hose nozzle 10 is reliably prevented from falling off. It will be.

In addition, since the protrusion 72 is projected from the lever 60 and the lever 60 is pivotally attached to the main body 26, the lever 60 is always integrated with the main body 26, and the hose nozzle 10 is connected to the hose nozzle holder. The incidental work such as storing the lever 60 when removing it from 58 becomes unnecessary. The hose nozzle 10 can be fixed to the hose nozzle holder 26 only by rotating the lever 60 around the fulcrum (pin 62).
Further, since the protrusion 72 closes the upper part 18a of the frame-shaped guard 18 and the pin 62, which is a fulcrum of the lever 60, is located further above the protrusion 72, the hose nozzle 10 is removed from the press plate 34. When the lower piece 18a of the frame-shaped guard 18 comes into contact with the protrusion 72, the force that pulls the protrusion 72 in the space direction sandwiched between the vertical wall portions 34a is applied to the lever 60. Accordingly, the protrusion 72 grips the frame guard 18 from the side more reliably, and the hose nozzle 10 is reliably prevented from falling off.

Further, since the stopper 74 of the lever 60 comes into contact with the vertical wall portion 34 a of the presser plate 34, the hose nozzle 10 is lifted from the presser plate 34, and the frame-shaped guard 18 comes into contact with the protrusion 72. The lever 60 does not further rotate around the pin 62 in a state where a force for pulling in the space direction sandwiched between the portions 34 a is applied to the lever 60, and the gripping state of the frame guard 18 by the protrusion 72 is ensured. Maintained.
In the illustrated example, by adjusting the tightening force of the nut 70, the elastic deformation amount of the disc spring 68 is adjusted so that the lever 60 is fixed at an arbitrary position even when the lever 60 is released. However, instead of the disc spring 68, the lever 60 may be constantly urged by the spring in a direction in which the stopper 74 of the lever 60 contacts the vertical wall portion 34a of the presser plate 34. In this case, when the hose nozzle 10 is attached to or detached from the hose nozzle holder 58, the operator opposes the spring, the lever 60, and the protrusion 72 from the notch 34c of the vertical wall 34a to the outside of the vertical wall 34a. Rotate to a position where it can be completely removed
