Description

[Detailed Description of the Invention] The present invention relates to a gripping tool handle, and more particularly to a gripping tool handle that can be detachably attached to a gripping tool such as a mop.

Various handles for gripping tools have been proposed in the past.
Conventional handles of this type have a structure in which the handle is connected to the motu gripping tool using a special shaft bearing structure, which not only requires complicated operations but also increases the assembly process and costs. It tended to be high.

The present invention was developed in view of the above-mentioned circumstances, and the object is to provide a gripper handle that has an extremely simple structure and can be attached to and removed from the mop gripper with a single touch. . Hereinafter, details of the present invention will be explained based on embodiments shown in the drawings.

1 to 4 illustrate an embodiment of the present invention, in which a handle 1 according to the present invention has a connecting member 3 fixed to the tip of a hollow pipe 2 formed from a metal tube or the like.

As shown in an enlarged view in FIG. 2, this connecting member 3 is formed by bending, for example, one continuous steel rod, and has symmetrical arms 4, 4. Each arm 4,
4 has a curved part 4a that spreads outward in the middle thereof,
The upper end of each arm 4 is bent into a U-shape and continues to the pipe.

Further, a straight part 4b is formed at the tip of each arm 4, 4, and the ends of the straight parts 4b are arranged in opposite directions.
That is, a bent portion 4c is formed which is bent outward at a right angle.

In the free state, the distance between the tips of the bent portions 4c, 4c of each arm 4, 4 is equal to
The interval is set to be narrower than the interval between 2 and 12.

The connecting member 3 having the above structure has a second
As shown in the figure, the connecting portion 4d is bent into a U-shape.
is fitted onto the tip of the pipe 2, and the portion between the arms 4 and 4 is caulked to form a caulked portion 2a, thereby being securely fixed inside the pipe 2.

On the other hand, the straight portions 4b of the arms 4, 4 of the connecting member 3,
An opening/closing member 5 for the arms 4, 4 is attached to 4b.

This opening/closing member 5 has a U-shaped cross section.
It consists of a pair of levers 6, 7, one lever 6 being short and the other lever 7 being long. The short lever 6 has a U-shaped cross section that is slightly smaller than the U-shaped cross section of the long lever 7, and can be accommodated in the long lever 7.

The two levers 6 and 7 have one end rotatably supported on the straight portions 4b of the arms 4 and 4, respectively.

The other end of the short lever 6 is rotatably connected to the middle of the long lever 7 via a pin 8. The long lever 7 has approximately twice the length of the short lever 6, and its free end side forms a knob 7a.

By the way, the position of the pin 8 that connects the two levers 6 and 7 is such that when the knob 7a side of the long lever 7 is pushed and the opening/closing member 5 is closed, the position of the pin 8 that connects the two levers 6 and 7 is such that the straight portions 4b and 4b are closed. It is located below the connecting line in FIG. 3, that is, at a position away from the levers 6 and 7. In this state, the straight portions 4b, 4b are pushed apart so that the distance between them is wider than in the free state, and therefore a force is acting that tends to bring them closer to each other.

However, as mentioned above, since the pin 8 is located below the straight line connecting the straight parts 4b, 4b, that is, beyond the dead center, the force that causes the straight parts 4b, 4b to approach each other is exerted by the lever 6. , 7, and the levers 6 and 7 receive a force that tries to overlap them further. Furthermore, as shown in FIG. 3, the knob portion 7a of the long lever 7 is in contact with the straight portion 4b on which the short lever 6 is supported. remains closed.

On the other hand, if the long lever 7 is raised by pinching the knob 7a and the pin 8 moves even slightly upward in FIG. 7 acts to open, and opens easily as shown in FIG.

Next, a method of using the pattern constructed as described above will be explained.

5 and 6 illustrate an example of how this handle is used. In the figures, the reference numeral 9 is a motsu gripper, and this gripper 9 is formed from a metal plate into a rectangular shape, and is shaped in the width direction. Both side edges of are bent portions 10, 10 that are bent upwardly and inwardly at a predetermined angle, and each bent portion 10,
The upper end of 10 forms a folded portion 10a which is folded back toward the outside. A mop 11 made of a foamed synthetic resin plate is attached to the lower surface of the gripper 9. The mop 11 is made of a base fabric 11a and a foamed sheet 11b, and both ends of the mop 11 in the width direction are fitted inside the folded portion 10a, and fixed by caulking the folded portion 10a.

On the other hand, a pair of projecting pieces 12, 12 are cut and raised parallel to each other along the width direction in the longitudinal center of the gripping tool 9, and the arms of the connecting member 3 are located at opposing positions of the respective projecting pieces 12. 4, the bent part 4c at the tip of 4,
A through hole 12a is formed into which the hole 4c is rotatably fitted.

The connecting member 3 is connected to the gripper 9 having such a structure.
To install it, proceed as follows.

First, as shown in FIGS. 2 and 4, put your finger on the knob 7a of the longer lever 7 of the opening/closing member 5 and raise it. Then, as mentioned above, the bent portions 4 at the ends of the arms 4, 4 which are given elasticity in the approaching direction
c and 4c are brought close to each other to the maximum extent possible, and the distance between the tips of the bent portions 4c and 4c is smaller than the distance between the protrusions 12 and 12 of the gripping tool 9. In this state, the tips of the arms 4, 4 are inserted between the protrusions 12, 12, and the tips of the bent portions 4c, 4c are opposed to the through hole 12a of the protrusion 12. Then, push down the knob 7a of the lever 7 so that the levers 6 and 7 are positioned in a straight line.

Then, the forces of the arms 4, 4 trying to approach each other act in a straight line, so the levers 6, 7 do not open. When the arms 4, 4 are pushed apart in this way, the space between the bent portions 4c, 4c opens, and the tips of the bent portions 4c fit into the through holes 12a of the projecting piece 12, respectively, and pass through the bent portions 4c. The connecting member 3 and the pipe 2 are rotatably connected to the gripper 9.

If you want to remove it, just raise the lever 7 and you can remove it with one touch.

FIGS. 7 and 8 are for explaining another form of use, and the reference numeral 13 in the figures is a gripping tool, which is formed by bending a steel wire or the like into a substantially base shape, and its both ends are inside. Bent part 13 folded back to
a, and the tip of the bent portion 13a is a circularly curved shaft bearing portion 13b.

The gripping tool 13 having such a structure is attached to a mop 14 as shown in FIG.

The mop 14 is formed into a bag shape by stacking two upper and lower base cloths 15 and 16 and sewing the peripheral edges thereof with a sewing machine, and the upper base cloth 15 has an opening 15a formed therein. The shapes of the base fabrics 15 and 16 are almost the same as the shape of the gripper 13. A large number of tufted bodies 14a are sewn to the lower side of the base fabric 16.

The gripping tool 13 is inserted between the base cloth 16 and the opening 15a of the base cloth 15. The method of attaching the connecting member 3 to the gripper 13 is also exactly the same as described above. To avoid duplication, the explanation will be omitted.

In addition, in the above-mentioned embodiment, the arms 4, 4 of the connecting member 3 were illustrated as being continuous, but
Of course, each one may be independent.

As is clear from the above description, according to the present invention, the opening/closing member is attached to a connecting member having two arms provided at the tip of the handle, and the opening/closing member is attached to the connecting member having two arms provided at the tip of the handle. Curved parts 4c, 4c
It has a structure that can be adjusted between a state in which the parts are in contact with each other and a state in which they are spread out, so the structure is simple, inexpensive, and easy to operate. A gripper handle can be provided.
