Abstract

PURPOSE:To improve the cleaning effect by attaching a brush bundle for turning back the tip of a slender brush hair material and forming a loop to a brush stand. CONSTITUTION:As for a brush hair material, that which is made of a synthetic resin containing grinding abrasive grains is desirable at a person's request. Especially, that which is formed by executing tension working in the longitudinal direction with respect to a filament of nylon, etc., containing grinding abrasive grains is desirable. A brush bundle 2 formed like a loop by turning back the tip of the brush hair material is attached to a brush stand by a fitting material 3 of a staple or a wire. As for the brush stand, either of that for a deck brush or a motor-driven floor polishing brush will suffice.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a bluff stand used in a deck brush, electric floor polisher, etc., and a method for manufacturing the same.

(B) Conventional Technology Conventionally, cleaning work for cleaning and polishing the floors of buildings and other structures has often involved the use of deck brushes and electric floor polishers.

A conventional deck brush has numerous brush bristles 1 planted in an upright manner on the underside of a brush stand.

In the case of an electric floor polisher, the brush bristle material l is a filament of nylon or the like containing a large number of abrasive grains, and a large number of the brush bristles l are placed upright on the brush stand. Use it by attaching it to the bottom end. When one of the brush bristles L is illustrated in FIG. 2, it has a small wave shape. The brush bristle material 1 is formed into a wavy shape in order to prevent it from sticking too tightly. This is because too close contact will not improve the cleaning effect.

By the way, in the case of brushes for electric floor polishers, the tips of the brush bristle material 1 are trimmed with a trimmer after being flocked in an upright manner, so the tips are very sharp. Therefore, when used for cleaning carpets, In this case, the plan bristles 1 dig into the carpet, damaging the carpet and making it difficult to operate.Therefore, before use, while rotating the brush stand idly, apply sandpaper to round the tip of the brush bristles 1. There is.

In addition, in the case of an electric floor polisher, attach the holder to the bottom end,
A scrubbing brush was often attached to the bottom of the holder. The scrubbing brush used was a non-woven fabric containing abrasive grains.

I cleaned the floor by moving the electric floor polisher little by little, but the scrubbing brush easily came off from the holder when I moved it. Furthermore, the scrubbing brush may be damaged when it hits a protrusion such as an electric wire on the floor, for example. If the scrubbing brush was not thoroughly cleaned after removing old wax, it would harden and become unusable.

I am using it (although the scrubbing brush is gradually wearing out,
At this time, uniform wear did not occur often, but non-uniform wear tended to occur. If the electric floor polisher wore unevenly, it would shake when rotating, making it difficult to operate. In the end, he was unable to drive. Furthermore, the scrubbing brush was worn down to about half its thickness (and became thinner), making it more prone to clogging.

When using a scrubbing brush, the above-mentioned problems occur, which is why there has been a movement towards using a brush. A brush formed using the brush bristle material 1 does not become clogged and does not require subsequent cleaning. It will not be damaged even if it hits a protrusion such as the floor. There is no need for a holder to hold the scrubbing brush.

(c) Problems to be Solved by the Invention In the conventional brush stand as described above, a floor surface, etc. is cleaned with the tips of a large number of brush bristles 1.

However, since the contact area with the floor surface is small, cleaning is not very effective.As the brush bristle material I is cleaned, the tips of the brush bristles I wear out and become rounded, and the cleaning effect gradually decreases. Furthermore, the brush stand may bend in the opposite direction to the direction of movement or fall in an undesirable direction, making it increasingly difficult to clean.

Therefore, the inventor of the present invention has proposed that if the side surface of the brush bristle material 1 is brought into contact with the floor surface etc. when cleaning, the contact area will be greatly increased, the above-mentioned inconvenience will be eliminated, and cleaning will be more effective. I thought that it should be done in the future.

The brush bristle material 1 shown in FIG. 2 is a filament made of nylon or the like in which countless abrasive grains are sealed. This brush bristle material 1 is subjected to tension processing in the longitudinal direction in order to have elasticity and strength. Therefore, the molecular structure is formed in the longitudinal direction. In other words, it is manufactured on the premise that it will be used with the tip in contact with the floor. and,
Only a small amount of abrasive grains are exposed at the tip of the brush bristle material 1. For this reason, cleaning at the tip does not work.

However, countless abrasive grains are exposed on the outer periphery of the brush bristle material 1. Therefore, the inventor also thought that if the numerous abrasive grains on the outer periphery could be used for cleaning, the cleaning effect would be significantly improved.

Furthermore, in the conventional brush stand, the bundles of brush bristle material l are in a relatively dense state. However, since the cleaning effect is better if the bristles are not too densely packed, the brush bristles 1 are formed into small wave shapes. However, because a sufficient gap is still not formed, the conventional cleaning method cannot perform efficient cleaning.

Therefore, the inventor thought that the cleaning effect would be improved if the distance between each brush bristle material was further widened.

Also, as mentioned above, before cleaning the carpet,
It was necessary to round off the tip of the brush bristles with sandpaper. This work was very tedious.

Therefore, the inventor thought that if the tip of the brush bristle material 1 is already rounded, there is no need to round it up again.

The problem to be solved by the present invention is how to use the outer periphery of the brush bristles 1 for cleaning work, and how to maintain a wide interval between the brush bristles 1. This and how the tip of the brush bristle material 1 can be made round.

(d) Means for Solving the Problems The brush stand according to the present invention solves the above problems, and is as follows.

In other words, a brush bundle 2 in which elongated brush bristle material l is folded back at the tip to form a loop at the tip is a brush stand attached with the attachment member 3.

The brush bristle material I is preferably made of synthetic resin containing countless abrasive grains, except for use in carpet brush stands. In particular, it is desirable to subject a filament of nylon or the like containing abrasive grains to tension processing in the longitudinal direction and then remove the filament. Such a material has appropriate elasticity and forms a desired loop when folded back.

As the mounting material 3, a crotch nail or wire may be used, or other materials may be used.

This brush stand may be used for a dirt brush or for an electric floor polisher.

There are many ways to make a brush stand. For example, the brush bundle 2 is formed by folding one or more of the elongated brush bristles in half, then folding the folded in half again in half, etc., and repeating the folding in half twice or more. This is a manufacturing method in which the last folded part of the brush bundle 2 is attached to the brush stand 4 with a mounting material 3.

The number of times of folding in half may be any number of times as long as it is two or more times. As the number of times increases, the number of loops formed in the brush bundle 2 increases.

In addition, one or more of the elongated brush bristles L are folded back on the left and right sides to form loops on the left and right, and the loops formed are folded in half to form the brush bundle 2, and the folded portion is folded in half to form a brush bundle 2. A manufacturing method of attaching it to the brush stand 4 using the attachment material 3 is also conceivable. Left and right "Fl to h: g- to - small #V may be only 1 in 6, or it may be any number of times of 1 or more on left and right.

Furthermore, after winding one or more of the elongated brush bristles 1 several times, it may be made into an elongated state (squeezed from side to side, folded back from side to side), and the rest may be carried out as described above.

There are many other ways to make this brush stand. Any manufacturing method may be used as long as a loop is formed at the tip of the brush bundle 2.

In addition, in the product manufactured as described above, only a loop may be formed at the tip of the brush bundle 2, or the free end of the brush bristle material 1 may be formed so as to partially reach the tip. good. Further, the cleaning effect will be improved if the heights of the loops are uneven.

(e) Many loops are formed at the tips of the many brush bundles 2 that have been acted upon. Therefore, when cleaning a floor surface, etc., these loops move on the floor surface, etc. while making contact with each other over a wide contact area. That is, the outer periphery of the brush bristle material 1 is brought into wide contact with the floor surface, etc., and cleaning is performed with a wide contact surface. Moreover, at this time, a large number of loops are caught on dirt, etc., and a force is generated to peel off the dirt, etc., and this force causes the dirt, etc. to be peeled off.

When a synthetic resin material containing countless abrasive grains is used as the plan bristles 1, the outer periphery of the brush bristles 1 is The chance that the exposed abrasive grains will come into contact with the floor surface, etc. is greatly increased.

Therefore, when the brush bristle material 1 moves on the floor etc.,
Countless abrasive grains rub against the floor, removing dirt from the surface.

Further, the large number of loops formed in the brush bundle 2' also serves to keep the intervals between the brush bristles 1 wide.

Furthermore, the large number of loops in each brush bundle 2 prevents the brush bristles 1 from digging into the carpet when cleaning the carpet.

Carpets in buildings and other areas are cleaned by turning the detergent into foam while the carpet is still on the floor. At this time, the numerous loops rotate to force the detergent (it also works to foam).

(f) Example Example 1 1 to 4 show a first embodiment.

Example 1 is an example in which the present invention is applied to a decking brush. The brush bristle material 1 used in Example 1 is the same as the conventional one shown in FIG. That is,
It is made of synthetic resin that contains countless abrasive grains.

Then, as shown in FIG. 3, some of the brush bristle materials I are arranged and folded in half, and then folded in half again. If it is folded in half again, it will become a brush bundle 2 as shown in FIG. Here, a conventionally used crotch nail is used as the mounting material 3, and the mounting material 3 is inserted into the folded portion of the brush bundle 2. Then, as shown in FIG. 1, the mounting material 3 is driven into a large number of tuft holes provided at equal intervals in the brush stand 4 of the decking brush, thereby completing the decking brush of Example 1.

Example 2 FIG. 5 shows a second embodiment.

Example 2 is an example in which the present invention is applied to a plan for an electric floor polisher. 5 indicates a disc-shaped base that is attached to the lower end of the electric floor polisher.

The base 5 is disk-shaped and has a round hole in the center. A brush stand 4 having the same shape as the base 5 is attached to the base 5 with screws. A large number of circular bristle-planting holes 6 are formed concentrically in several rows in the brush stand 4.

A conventional straight bristle brush 7 is implanted in the outer peripheral row of the tuft holes 6. Then, the remaining tuft holes 6 on the inside
A brush bundle 2 with a loop is planted in the. That is, insert the wire used as the mounting material 3 into the folded part of the brush bundle 2 as shown in FIG. It is there.

Example 3 FIG. 6 shows Example 3.

In the third embodiment, the base 5 is not used.

A large number of circular bristle-planting holes 6 are formed concentrically in several rows in a circular brush stand 4.

Brush bundles 2 and straight bristle brushes 7 are alternately implanted in these bristle-planting holes 6. It should be noted that various other ways of combining the brush bundle 2 and the straight-bristle brush 7 are conceivable.

Example 4 FIG. 7 shows Example 4.

Reference numeral 5 indicates a base that is attached to the lower end of the electric floor polisher. The base 5 has 8 penetrating round holes 8 spaced at equal intervals.
I have one open.

Eight separate brush stands 4 are prepared. Each brush stand 4 has a shape equal to one of eight pieces obtained by dividing the base stand 5 at equal angles. Both side surfaces are inclined surfaces 9 that are inclined in the same direction at an angle of about 30 degrees. Each brush stand 4 is provided with a through hole IO passing through it in the vertical direction. The diameter of the through hole 10 is made to match the diameter of the hole 8 of the base 5. The upper part of the through hole 10 is slightly enlarged.

The brush stand 4 has several bristle-planting holes 6 inclined at the same angle and in the same direction as the inclined surface 9. In each tufting hole 6,
Brush bundles 2 each having a large number of loops formed therein are implanted. A separate fixture 11 is prepared. Mounting tool 11
is in the shape of a pipe whose outer diameter matches the diameter of the hole 8 of the base 5 and the through hole 10 of the brush stand 4. The upper part is an enlarged part of a size that just fits into the enlarged part above the through hole 10 of the brush stand 4. The length of the fixture 11 is made to be slightly longer than the sum of the thickness of the base 5 and the thickness of the brush stand 4.

To attach eight brush stands 4 to the base 5, do as shown in FIG. That is, one hole 8 of the base 5 and the through hole 10 of one brush stand 4 are aligned,
One fitting 11 is pushed into the hole 8 from the through hole IO.

The fixture 11 fits snugly, and the brush stand 4 is firmly fixed to the base 5 by frictional force. As described above, the eight brush stands 4 are attached one after another. When installed, adjacent brush stands 4 overlap each other on the inclined surfaces 9 on both sides and are in close contact with each other.

The item shown above is attached to the bottom end of the electric floor polisher when in use. When the weight of the electric floor polisher is applied, the brush bundle 2 installed at an angle is pressed down and lies down, and the outer periphery of each brush bristle material 1 comes into contact with the floor surface or the like. Therefore, the total contact area of the entire brush bristle material l with the floor surface etc. becomes extremely large.

When the electric hoshin machine is rotated, the sides of the many brush bristle materials l of each brush bundle 2 come into contact with each other over a wide contact area, and the brush bristle material 1 rotates while generating a strong frictional force. Since it is a loop, the force for removing dirt from the floor surface, etc., is strong at this time.Therefore, the floor surface, etc. is powerfully cleaned with the entire lower surface of the base 7.

During use, if the brush bundle 2 becomes partially worn out and becomes unusable, the brush stand 4 that has become unusable
Then, pull out the fixture 11. Remove the brush stand 4 and install a new brush stand 4 in its place.

Example 5 FIG. 8 shows an enlarged view of the main part of the fifth embodiment.

In the fifth embodiment, the tufting holes 6 are formed in an oval shape. Therefore, the brush bundle 2 planted in the tufting hole 6 is spread out in a fan shape. If the brush stand is moved in a direction perpendicular to the fan-shaped spread, the cleaning effect will be improved.

(g) Effect of the invention When cleaning with the brush stand according to the invention, the brush bundle 2
The outer periphery of the large number of loops, that is, the outer periphery of the brush bristle material l moves while contacting the floor surface etc. over a wide contact area. Cleaning while contacting with an extremely wide contact area,
Coupled with the fact that the large number of loops pulls off dirt, etc.,
Cleaning will continue to be extremely effective.

When a synthetic resin material containing countless abrasive grains is used as the brush bristles 1, the abrasive grains exposed on the outer periphery of the brush bristle material 1 move while contacting each other over a wide contact area. Therefore, the cleaning effect is greatly improved.

Moreover, each brush bristle material 1 is kept widely spaced from each other due to the large number of loops of the brush bundle 2.

Therefore, it has the same cleaning and polishing effects as a scrubbing brush. Also, unlike a scrubbing brush, it will not clog.

When cleaning a carpet, the large number of loops will not damage the carpet (and will not make it difficult to maneuver.) The detergent's suds will also work well (and will help clean the carpet).
