JPH119536A - Attaching utensil for yarn mop - Google Patents

Abstract

PROBLEM TO BE SOLVED: To easily attach/detach an inexpensive yarn mop for replacement to/from an attaching utensil. SOLUTION: This attaching utensil comprises a cover 1 and a supporting bar 11 to which a yarn mop 23 is attached, and a box-shape cover main body 2 has an attaching part 7 which is attached to a pinching claw at the tip end of a handle, on the upper surface, an upper surface opening 4 at both ends of the upper surface, and an engaging claw 6 under the opening 4. The supporting bar has a spring part 13 at both ends of a base part 12, and a stopper 14 which erects from the spring part. For the stopper, a gap of the stopper is formed to be smaller than the gap of the engaging claw so that the stopper may be engaged with the engaging claw when the supporting bar is pushed into the main body, and the stopper may be opened when being widened and depressed. Thus, the yarn mop can be attached/detached to/from the attaching utensil by simply pushing in the supporting bar to which the yarn mop is attached, or widening and depressing the stopper.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixture for attaching and detaching a thread mop used for wiping a floor or the like.

[0002]

2. Description of the Related Art Some conventional thread mop can be replaced because the thread mop can be directly attached to and detached from a fixture at the tip of a handle. Further, there is a type in which a thread mop is sandwiched and fixed to a plastic mounting frame to be integrated with the thread mop. In the latter, the pinching claw at the tip of the handle is locked in a groove formed in the mounting frame, and attaching and detaching the thread mop to and from the handle is convenient because the pinching claw only needs to be opened and closed. However, there is a disadvantage that the cost is higher than that of the exchangeable type because of the plastic mounting frame. On the other hand, the interchangeable type has a drawback that the means for attaching and detaching to and from the fixture is complicated, it takes time and effort to attach and detach, and it is difficult for women and children to attach and detach because it requires power.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to make it possible to attach and remove an inexpensive replacement thread mop to and from a fixture very easily without requiring any force.

[0004]

SUMMARY OF THE INVENTION A thread mop attachment according to the present invention has the following features. That is, it is composed of a cover and a support bar for attaching the yarn mop. The main body of the box-shaped cover having an open bottom is provided with a mounting portion detachably attached to a clamping claw at the tip of a handle at the center of the upper surface, an upper surface opening at both left and right ends of the upper surface, and an upper surface opening. A locking claw below the portion.

The support bar has spring portions at both left and right ends of a base portion and stoppers rising from the spring portions, and the stoppers are locked by locking claws when the support bar is pushed into the main body. The distance between the two stoppers is smaller than the distance between the two locking claws so that the stopper can be released from the locking claws when it is spread outward and pressed down.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a cover 1 will be described with reference to FIGS. 1 to 5. Reference numeral 2 denotes a U-shaped cross section that opens downward except for both left and right ends, that is, an elongated box shape with an open bottom. It is the main body. Reference numeral 3 denotes a side opening, which is provided at the lower part of the left and right side surfaces of the main body 2, as is apparent from FIG.
Reference numeral 4 denotes an upper surface opening, which is provided at both left and right ends of the upper surface of the main body 2.

Reference numeral 5 denotes a locking portion located below the upper surface opening portion 4, which is convexly curved upward from the center end of the upper surface opening portion 4 and extends downward. A locking claw 6 having an outer surface 6 'that is inclined down is provided. The reason why the locking portion 5 is formed downward is that a gap is formed between the upper surface opening 4 and the upper surface of the locking portion 5 so that a stopper 14 described later can be easily opened with a thumb.

[0008] Reference numeral 7 denotes a known mounting portion, which is provided at the center of the upper surface of the main body 2. An engaging groove 8 fixed to the tip of a handle 21 shown in FIG. 8 and detachably engaged with an openable / closable sandwiching claw 22 is recessed in a lower part of the front and rear of the mounting part 7. Note that the cover-1 is integrally formed of a hard plastic.

Next, referring to FIGS. 1, 6, and 7, a support bar will be described.
11 will be described. Reference numeral 12 denotes a base portion of the support bar 11, which extends in a belt shape to the left and right, and both end portions of which are curved in an outwardly convex semicircular shape having a center point upward to form a spring portion 13. Reference numeral 14 denotes a stopper, which has a notch 15 that rises slightly inward from the spring portion 13 and locks at the upper end of the locking claw 6.

Reference numeral 16 denotes a large rib in the form of a plate, which rises from the longitudinal center line on the upper surface of the base 12 and is connected to the spring portion 13 after the left and right ends thereof are inclined down. The large rib 16 is mounted with the thread mop 23 that has been sorted back and forth, and also serves to reinforce the support bar 11. The base portion 12 is formed narrow to the lower end of the spring portion 13, and when the support bar 11 to which the thread mop 23 is attached is pushed into the cover 1, the cover 12 is closed.
The thread mop 23 can be sandwiched between the inner wall 1 and the base 12. The support bar 11 is also integrally formed of hard plastic. Here, the left-right space of the stopper 14 is formed smaller than the left-right space of the locking claw 6.

Although not shown, a plurality of ribs are provided on the inner wall of the main body 2, and a plurality of ribs for connecting the base 12 and the large rib 16 are provided on the support bar 11, respectively. These rib groups have a function of reinforcing the main body 2 and the support bar 11, respectively, and also have a function of clamping the yarn mop 23 between the main body 2 and the support bar 11.

[0012] From the above configuration, first, both ends of the mop thread connecting tape (not shown) are sandwiched between the spring portions 13.
The connecting tape of the yarn mop 23 is placed on the support bar 11, and the yarn mop 23 is sorted back and forth. When the support bar 11 is pushed in from below the main body 2, the left and right spaces of the stopper 14 are formed to be smaller than the left and right spaces of the locking claws 6. Is getting bigger and bigger. At this time, the stopper 14
The upper end of the stopper 14 smoothly rises while being guided by the outer side surface 6 ′ of the locking claw 6, and the interval between the stoppers 14 increases.

Finally, the upper end of the stopper 14 comes out of the upper opening 4 and the notch 1 of the stopper 14 is
5 abuts, the interval between the stoppers 14 is reduced by the action of the spring portion 13, and the stoppers 14 are locked by the locking claws 6,
The yarn mop 23 is fixed by the main body 2 and the support bar 11 (see FIG. 1). At this time, since the side opening 3 is provided in the main body 2, the spring portion 13 does not interfere with the main body 2.

When the yarn mop 23 is to be removed for replacement, if the left and right stoppers 14 are opened outward and pressed down, the support bar 11 comes off the main body 2 so that the yarn mop 23 can be easily taken out.

[0015]

The yarn mop can be fixed to the fixture simply by pushing the support bar sandwiching the yarn mop into the main body, and the support bar can be removed from the cover by pushing down while opening the stopper. Exchanges can be made easily without the need for power.

Also, since the structure is extremely simple and can be easily molded with hard plastic, it can be provided at a low cost, and as in the case of the thread mop fixed to the mounting frame, the mounting frame is wasted when the thread mop is replaced. Absent.

Since the support bar is provided with a spring portion,
It can handle yarn mops with slightly different widths and thicknesses.
