Description

[Detailed Description of the Invention] The present invention relates to a mop holder, and more particularly to a highly durable mop holder that allows the mop to be attached and removed with a single touch.

Conventionally, it has a pair of clamping pieces, one of which can be opened and closed via a lever, and the bearing point between the lever and the clamping piece is moved beyond a certain dead center using the elasticity of the lever or the clamping piece. A mop gripping tool is known that allows the mop to be firmly gripped or released by holding the mop firmly.

However, since this type of conventional motsu gripping tool utilizes the elasticity of the lever or the clamping piece, it has the disadvantage that the bearing point between the lever and the clamping piece wears out and the gripping force becomes ineffective. It was hot.

The present invention has been made in order to eliminate the above-mentioned drawbacks of the conventional mop clamping tool, and provides a motsup clamping tool that does not cause friction in the bearing part between the lever and the clamping piece, and maintains a gripping force for a long period of time.

On the other hand, the shaft bearing part 5 has a structure as shown exploded in FIG. 3.

That is, the shaft bearing part 5 includes a screw shaft 37, a screw cylinder 38 into which this is screwed, a rotary cylinder 39, a washer 40, and an O.

It is inserted into the through hole 15 in a state where it is opposed to the notch 15b. In this state, the key 42 is fitted into the notch 38c, and the bent part 42a of the key 42 is fitted into the notch 15b, so that the threaded cylinder 38 is prevented from rotating.

The threaded cylinder 38 is formed with a female threaded part 38d passing therethrough, into which the threaded shaft 37 is threaded, and a groove 38e is formed along the axial direction at opposing positions on the outer peripheral surface of the threaded cylinder 38.

A large diameter cylinder 39c is provided on the side surface of the rotating cylinder 39.
A small-diameter cylindrical portion 39d is formed continuous with this, and a mop handle 44 or the like is fitted and fixed to the small-diameter cylindrical portion 39d.

Next, a method of using this embodiment configured as above will be explained.

First, when the rotating frame 3 is open, the first
As shown in FIG. 0, the operating lever 4 is rotated counterclockwise in the figure about the shaft 17, that is, in a direction away from the fixed frame 2. This pulls the link lever 31, and the lever 4 is rotated through the link lever 31. The rotating frame 3 is pulled wide open.

In this state, the shafts 36 and 31a are located outside the vertical straight line l passing through the shaft 17.

In this state, the motsu 4 is placed between the fixed frame 2 and the rotating frame 3.
Insert the upper end of 3. And operation lever 4
When the rotating frame 3 is rotated clockwise around the shaft 17 in the figure, the rotating frame 3 is pushed through the link lever 31 as shown in FIG. 11, and the rotating frame 3 approaches the fixed frame 2 side. . Then, the protrusions 7 and 27 protruding from the inner surfaces of the fixed frame 2 and the rotating frame 3 bite into between the tufted fibers of the mop 43. At this time, rotation frame 3
Since the upper end of the rotary frame 3 fits into the recess 20 formed on the fixed frame 2 side, the rotary frame 3 can be rotated smoothly.

During the clockwise rotation of the operating lever 4, as shown in FIG.
There is a point in time when they line up on the straight line l. This point is the dead center, and in this state, the distance between the shaft 17 and the shaft 31a becomes the maximum distance, and if the shaft 36 is fixedly supported, the operating lever 4 can no longer be rotated clockwise. I can't move. However, since the shaft 36 is located in the long hole 35a of the link lever 31 and is elastically supported by the coil spring 34,
This coil spring 34 can be bent and lowered.

Therefore, the operating lever 4 will be rotated further in the clockwise direction. As a result, only the shaft 36 moves beyond the straight line 1, that is, beyond the dead center, toward the rotating frame 3, as shown in FIG. In this state, since the spring 34 is also inclined toward the rotating frame 3 side from the straight line 1, a component force is generated in the horizontal direction and toward the fixed frame 2 side. This component of force becomes a force that keeps the operating lever 4 in the closed state, and the operating lever 4 is in a locked state. For this reason, the rotary frame 3 is also kept closed as it faces the fixed frame 2, and the mop 43 is securely gripped.

In addition, since the gripped motsup 43 is strongly gripped, it has elasticity that tries to restore itself, and gives a force that tries to open the rotating frame 3, but this force conversely causes the shaft 36 to move further away from the straight line l. This will give a force in the direction of entering the inside, and the rotation frame 3 and the operating lever 4
never opens.

When attempting to remove the mop 43, place your finger on the lower end of the operating lever 4 and apply a large external force in the direction of opening the operating lever 4. This will cause the coil spring 34 to bend in the opposite direction to that described above. At the same time, the shaft 36 crosses the dead center and exits the straight line l. At this time, the restoring force of the clamped mop is also added, and the rotating frame 3 opens vigorously. If the mop 43 is removed from the projections 7 and 27 in this state, the mop can be easily removed.

On the other hand, in the bearing member 5, when the screw shaft 37 is strongly screwed into the screw tube 38, the screw tube 38 is attached to the screw shaft 38.
7 side, the O-ring 41 is elastically deformed and crushed, and the force to restore it is applied to the small-diameter portion 39 of the rotary cylinder 39 via the washer 40.
It acts on the side edges of a. As a result, the other side edge of the rotary tube 39 is strongly pressed against the protrusion 12 side, and a large braking force is applied to the rotation of the rotary tube 39. Therefore, coins etc. can be attached to the screw shaft 3.
By fitting into the groove 37b of No. 7 and adjusting the tightening force, the braking force on the rotary cylinder 39 can be freely adjusted.

Note that when the rotary tube 39 rotates, the rotary tube 39 rotates in contact with the washer 40 and the inner surface of the protrusion 12,
Since both the washer 40 and the protruding piece 12 are fixed, no torsional force is applied to the O-ring 41. Therefore, the O-ring 41 does not twist, and since no frictional force is applied to it, it does not wear out. As a result, the O-ring 41 has a long life and can provide braking action over a long period of time.

As is clear from the above explanation, according to the present invention, a spring such as a coil spring is attached to the link lever that communicates between the operating lever and the rotating frame,
This spring connects the link lever and the operation lever, and uses a structure that presses a shaft movably provided in a long hole formed in the link lever, so the link lever and the operation lever can be connected. When the connecting shaft crosses the dead center, it can be crossed while bending the spring. As a result, compared to conventional structures that rely on the elastic deformation of link levers and operating levers themselves, the result is that no excessive force is applied to the members, no wear occurs even after repeated use, and the durability is high enough to last for a long time. Certain mop grippers can be obtained.
