Description

[Detailed description of the invention] The present invention relates to a motsup holder, and more particularly to a motsup holder configured so that a motsup can be held at the tip of the handle by an openable and closable frame integrally formed from synthetic resin. It is something.

Traditionally, polypropylene and other materials have been used to create bilaterally symmetrical,
There is also known a mop holder that holds a mop through a frame that can be freely opened and closed.

This type of conventional motsup gripping tool clamps the center part of the motsupu via a gripping tool attached to the tip of the handle and applies a force to close it against the frame body. It had a structure in which pins protruding from the side were inserted into the motsu to hold it in place.

However, in the conventional structure of the mop holder as described above, the frame itself has a flat cross-sectional shape with a certain curved surface, and does not have reinforcing ribs to prevent deformation.

For this reason, if force is applied only to the center of the frame that holds the motsupu through the gripper attached to the tip of the handle, during long-term use, external force will only be applied to the center and the ends will not be affected at all. Since no force is applied, both ends of the frame open, the motsupu loses its grip, and both ends of the motsupu come off the frame, or the motsupu falls off from the frame. .

The purpose of this invention is to be able to securely hold the motsupu,
To provide a mop clamping tool that does not lose its clamping force on the mop and does not deform even when used for a long period of time.

Hereinafter, details of the present invention will be explained along with embodiments shown in the drawings.

In the figure, what is designated as a whole by the reference numeral 1 is a frame body, and this frame body 1 is made of a synthetic resin such as polypropylene and is made of left-right symmetrical frame pieces 2.
, 2 are integrally molded in a state where they are connected at their central portions.

The connection portion between the left and right frame pieces 2.2 is a thin wall portion 3, and due to the effect of the polypropylene material, this thin wall portion 3 serves as a hinge portion that will not break even if it is bent many times.

The length of the left and right frame pieces 2, 2 is almost the same as the length of the upper end of the mop 4, and in the case of this embodiment, as is clear from FIG. It is formed into a curved, almost L-shape.

As is clear from FIG. 3, short long grooves 5 are formed on one side of the outer surfaces of the frame pieces 2, 2 at equal distances from the thin wall portion 3, and long long grooves 6 are formed on the other side. has been done.

Inside these long grooves 5 and 6 are mop grippers 14, which will be described later.
15 gripping pieces are fitted.

On the free end side of each frame piece 2, bent portions 7 bent inward are continuously formed, and these bent portions 7 extend along the longitudinal direction of the frame piece 2, as shown in FIG. are formed at predetermined intervals, and arc-shaped recesses 8 are formed between each bent portion 7 .

Therefore, a plurality of bent portions 7 are formed in a sawtooth shape.

On the other hand, as is clear from FIG. 6, on the inner surface of each frame piece 2, a plurality of reinforcing ribs 9 (in this embodiment, three reinforcing ribs 9) are protruded in parallel along the longitudinal direction. has been done.

Moreover, three protrusions 10, 11 are provided on the inner surface of each frame piece 2, 2 to protrude inwardly.

The three protrusions 10 protruding from one frame piece 2 and the three protrusions 11 protruding from the inner surface of the other frame piece 2 are not formed on the same axis, but are shifted in position. It is installed protrudingly.

Therefore, when the frame piece 2.2 is closed, the tips of the protrusions 10.11 do not come into contact with each other.

As is clear from FIGS. 8 to 10, each protrusion 10.11 is formed as a flat triangular shape, and protrudes in a state perpendicular to the longitudinal direction of the reinforcing rib 9 and the frame pieces 2, 2. When the frame pieces 2, 2 are closed, the upper sides of the triangular protrusions 10, 11 are designed to be approximately horizontal, as shown in FIG.

This is to prevent the mop 4 from coming off the protrusions 10 and 11 even if a tensile force is applied to the mop 4 when it bites into the mop 4, as will be described later.

With the ε roller, a protrusion io, r located at the center of each frame piece 2.2
A protrusion 12 is provided on the opposite frame piece at a position facing t so as to be flush with the edge of the reinforcing rib 9.

The width of this protrusion 12 is about two to three times the thickness of the protrusion 10.11, but its length is long enough to cover all three reinforcing ribs 9.

The purpose of forming this protrusion 12 is to regulate the degree of closing of each frame piece 2 when the two frame pieces 2 are closed, as shown in the sectional view of FIG. This is to regulate the curved portions 7, 7 to be in a substantially horizontal state with their tips separated by a predetermined distance.

That is, when the frame pieces 2, 2 are closed to a predetermined degree, the protrusion i
o and ti come into contact with the protruding portion 12 of the opposing fragment, and serve as a stopper to prevent further damage.

On the other hand, what is indicated by the reference numeral 13 is a gripping tool, which is composed of a pair of left and right gripping pieces 14 and 15.

One gripping piece 14 has a cylindrical part 14a at its upper end,
The lower end part widens toward the end to become a flat plate, and a bent part 14b, which is also flat, is formed at the lower end.This bent part 14b is bent inward. A folded portion 14C is formed.

A flat plate-shaped protrusion 14d is integrally and bulged out in parallel on both sides of the inner side of one gripping piece 14, and a pin 16 is inserted between the protrusions 14d and the other gripping piece 14. 15 is rotatably supported on the shaft.

The gripping piece 15 has a housing portion 15a whose upper end is open on the inside.
This housing portion 15a has a pair of left and right protruding portions 1.
It is rotatably supported by a pin 16 while being held between 4d and 14d.

Further, the lower end of the gripping piece 15 is a curved part 15b having a curvature that almost matches the curvature of the outer peripheral surface of the frame piece 2, and the lower end of this curved part 15b is bent inward. A folded portion 15c is formed.

A through hole is formed in the front side of the housing portion 15a of the gripping piece 15, and a recess 14e formed on the gripping piece 14 side is inserted into the throughhole as shown in cross section in FIG. With the heads fitted, the tip of the screw 17 inserted into the gripper 13 is fitted, and the wing nut 18 is screwed onto the end of the screw 17 protruding from the housing portion 15a.

A spring 19 is elastically loaded between the inner surface of the housing portion 15a and the inner side of the recess 14e, and the gripping piece 14
, 15 provide elasticity in the opening direction.

Folded portions 14c formed at the tips of the gripping pieces 14, 15
and 15e are long grooves 5 formed on the outside of the frame pieces 2, 2.
, 6, and the folded portions 14c, 15c are fitted into the long grooves 5, 6.
If the wing nut 18 is tightened in a state where the two gripping pieces 14 and 15 are fitted into each other, the tips of the two gripping pieces 14 and 15 will approach each other, and the frame body 1 can be closed.

A handle 2 is provided in the cylindrical portion 14a formed at the upper end of the gripping piece 14.
The lower end of 0 is fitted and fixed.

Next, a method of using the clamping portion configured as described above will be explained.

First, as shown in FIGS. 3 and 4, the frame 1 is opened with the left and right frame pieces 2, 2 open, and the upper end of the mop 4 is attached to the frame pieces 2, 2.
Close the frame pieces 2, 2 by placing them on the lower side and applying force with your hands.

Then, as is clear from the cross-sectional view in FIG. 2, each frame piece 2
The triangular protrusion to, ii formed on , 2 is motsupu 4
It digs into the inside.

Since the protrusions to and ii are formed in the shape of a triangular flat plate, the wedge effect allows the mop, which is held perpendicular to the longitudinal direction of the frame piece 2, to easily bite into the space between the string-like wiping pieces.

At the same time, bent portions 7, 7 formed at the lower ends of each frame piece 2, 2
It also bites into both sides near the upper end of the mop 4.

In this state, if the folded parts 14c, 15c at the tips of the gripping pieces 14, 15 of the gripping tool 13 are fitted into the long grooves 5.6 of the frame pieces 2, 2, and the wing nut 18 is tightened, the gripping pieces 14, 15 can be opened. The tips approach each other and apply a force in the closing direction from the outside of the frame piece 2.2.

As a result, the frame pieces 2, 2 begin to close further, but as soon as the projection 10.11 comes into contact with its opposite projection 12, it can no longer close.

Therefore, a certain degree of closure is maintained for the frame 1.

In this way, even if a large force is applied to the center of the frame 1, the clamping tool 13 applied to the center of the left and right openable and closable frame pieces 2, 2 constituting the frame 1 will retain the protrusion io. 1i
Since it comes into contact with the protrusion 12 formed on the other frame piece 2 and plays the role of a stopper, it does not deform the center part of the frame 1 and prevents the frame 1 from opening at both ends. No deformation occurs.

As shown in FIG. 3, the left and right frame pieces 2.2 have their central parts slightly bulged outward and are wider than both ends, so that the frame pieces 2.2 When closed, both ends of the frame pieces 2, 2 have the effect of being difficult to deform into a trumpet shape.

As is clear from the above description, according to the present invention, the gripping part of the motsupu is constructed as a pair of left and right integrally molded frames that can be opened and closed, and a plurality of Since the reinforcing ribs are formed on each frame piece, deformation of the frame pieces is difficult to occur, and among the plurality of protrusions protruding from the inside of each frame piece, the protrusion located in the center is a piece of debris from the other frame piece. Because it comes in contact with the protrusion formed on the 1. The frame pieces 2, 2 are deformed by the external force applied to them, and the frame pieces 2, 2 are kept at a predetermined degree of closure. The mop will not come off or fall off without causing deformation.

In addition, since the protrusions are shaped like a flat plate perpendicular to the axial direction of each fragment, and have a thin triangular tip, they are easy to get into by motsupu flea, and when the left and right frame pieces are completely closed, the top of each protrusion Since the mop is horizontal, even if an external force is applied to the mop in the direction of pulling it out, the mop remains stuck in the mop and can be held securely.
