DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor surface applicator for applying wax, detergent, sterilizing solution, etc. to a floor surface.

[0002]

2. Description of the Related Art In recent years, floor materials have become abundant, and there are stone materials such as granite and marble, textile products such as old-fashioned wood, carpets and carpets, and P-tiles and vinyl sheets which are most widely used. Conventionally, P tiles have been constructed with a thickness of 3 mm, but in recent years, thin materials having a thickness of 2 mm have become mainstream. In addition, due to a shortage of construction engineers, a phenomenon that floor materials become uneven from the beginning of new construction is observed. Patterned tiles have also become widespread, and the tiles themselves have irregularities from the beginning.

[0003] Conventionally, a mop is most often used for applying wax or a detergent to a floor surface. However, the conventional mop consumes a large amount of wax and detergent, which is not only economically wasted but also causes pollution.

[0004] In order to reduce the consumption of wax and detergents, there are various types such as those using a brush, those having a plate-shaped object with rubber or vinyl with irregularities, and those having a plate-shaped object subjected to stripe processing. The cloth covered is used. However, such a conventional floor coating machine cannot sufficiently cope with the above-mentioned unevenness of the floor, and requires considerable skill in order to perform coating without causing uneven coating.

[0005]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a floor coating system which can save wax and detergent, and can be applied evenly by a beginner even when the floor surface has irregularities. Is to provide a machine.

[0006]

Means for Solving the Problems As a result of earnest study, the present inventor has achieved the above object by improving the structure of the coating portion attached to the tip of the handle, and has completed the present invention.

That is, the present invention relates to a floor coating machine having a pattern, a coating section attached to the tip of the pattern, and a means for supplying a coating liquid to the coating section, wherein the coating section has a plate shape. A coating section main body, three coating bars attached to a lower surface of the coating section main body via elastic means, and an outer cloth for covering the three coating bars. The three bars are disposed substantially parallel to each other in a direction whose longitudinal direction is substantially perpendicular to the traveling direction of the floor coating machine, and one bar is arranged in the traveling direction of the floor coating machine. The front bar arranged at the front has irregularities on its lower surface, and the central bar arranged at the center has irregularities on its lower surface, and the irregularities are applied to the floor surface. The part where the front bar is convex when viewed from the machine traveling direction is the concave part, and the front bar is the concave part. Is formed in a convex portion, the lower surface of the rear bar disposed rearward in the direction of travel of the coating machine, the floor surface coating machine characterized in that it is formed substantially flat. provide.

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view schematically showing a floor coater according to the present invention. A coating section 4 is attached to the tip of the handle 2. A tank 6 for accommodating wax, detergent and the like is provided in the middle of the handle 2, and a hose 8 extends from the tank 6 and is connected to the coating section 4 . Lever 1 at base end of handle 2
When the lever 10 is gripped, the wax or detergent contained in the tank 6 is applied to the coating unit 4 via the hose 8.
Supplied to The above configuration is the same as the conventional floor coating machine.

The floor coating machine of the present invention is characterized by the structure of the coating unit 4 . The application section 4 has a plate-shaped application section main body 12. A front bar 14, a center bar 16, and a rear bar 18 are provided on the lower surface of the application unit main body in this order from the front in the traveling direction of the floor surface application machine. Each of these three bars is arranged in a direction whose longitudinal direction is substantially perpendicular to the traveling direction of the coating machine, and
The three are arranged so as to be substantially parallel to each other. A magic tape (registered trademark) is provided on the front surface 19 and the rear surface 19 'of the coating section main body 12, and an outer cloth (not shown in FIG. 1; FIG. 5 to FIG. 7) covering the lower surfaces of the three bars. 21) is bonded to the front end and the rear end, respectively. As will be described in more detail later, a coating liquid such as a wax or a detergent is supplied to the inner surface of the outer envelope and applied to the floor via the outer envelope. The outer cloth may be a normal cloth, or may be durable paper, synthetic resin paper, cloth, or the like that can perform the same function as the cloth. These are also referred to as envelopes in this specification. FIG.
20, 22, and 24 are described in more detail later,
Front bar 14, center bar 16 and rear bar 1 respectively
It is a wire stopper that holds the wire that suspends 8.

FIG. 2 shows a view of the coating section 4 as viewed from below. FIG. 3 is a perspective view of the three bars disassembled and viewed obliquely from above. The lower surfaces of the front bar 14 and the center bar 16 are provided with irregularities as shown in FIGS. The projections 14a and 16a of these bars
The width of the recesses 14b and 16b is not particularly limited, but is about 2 to 3 cm. In addition, the step between the convex portion and the concave portion is
Although not particularly limited, it is preferably about 3 mm to 10 mm. When viewed from the direction of travel of the coating machine, the portion of the center bar 16 immediately behind the portion where the front bar 14 is convex is a recess. Conversely, in a portion where the front bar 14 is a concave portion, a portion of the central bar 16 immediately behind the convex portion is a convex portion. In this way, when viewed from the traveling direction of the coating machine, the unevenness of the front bar 14 and the rear bar 16 is combined alternately, and when the coating machine moves in the traveling direction,
The floor is pressed by at least one of the protrusions. On the other hand, the lower surface of the rear bar 18 is flat as shown in FIG. The holes 26 and 26 ', 28 and 28' and 30 and 30 'shown in FIG. 2 are holes for fixing the ends of the wires for hanging the front bar 14, the center bar 16 and the rear bar 18, respectively. . Numerals 32 and 32 'shown in the center bar 16 are nozzles provided at the tip of the hose 8, from which wax and detergent are dropped onto the outer cloth. It is preferable that the tip of the nozzle slightly protrudes from the bar (for example, about 1 mm) because the drop of the coating liquid is smoothly performed. Needless to say, the positions of the holes and nozzles are not limited to those shown. Also, holes 34 and 3 shown in FIG.
4 ', 36 and 36' and 38 and 38 'are holes for penetrating wires to be described later and for receiving springs. Further, reference numerals 40 and 40 'shown in FIG. 3 are holes for penetrating the nozzle. Holes 40 and 40 '
Is preferably slightly larger (for example, about 2 mm) than the outer shapes of the nozzles 32 and 32 '. Such play allows some movement of the bar in the lateral direction.
On the other hand, when an excessive lateral force is applied to the bar, the nozzle functions as a stopper.

The material of the three bars is not particularly limited, and any material may be used as long as it is a solid material. However, if the three bars have a certain degree of flexibility in the longitudinal direction, they can better cope with irregularities on the floor surface. It is preferable to use a material having For example, when the thickness of the concave portion is set to 3 to 5 mm, favorable longitudinal flexibility can be provided by employing a material such as an ABS resin.

The front bar 14, the center bar 16 and the rear bar 18 are attached to the coating section main body 12 via elastic means. One example of this mode of attachment is schematically shown in FIG. FIG. 4 shows an example in which the front bar 14 is attached to the application unit main body 12 via holes 26 (see FIG. 2) and 34 (see FIG. 3) provided in the convex portion of the front bar 14 via elastic means. It shows. Hole 34 described above (see FIG. 3)
Is shallow (for example, about 1
mm) It has a cut recess 34b. The front bar 14
It is hung on the application part main body 12 by a wire 44 passed through a hole penetrating the penetrating part 34a and the application part main body 12. The upper end of the wire 44 is a flat wire stopper 20
(See FIG. 1), and the lower end of the wire 44 is caulked inside the hole 26 (see FIG. 2). That is, the wire is penetrated through a cylindrical metal member made of a material such as copper, brass or stainless steel, and the metal member is pressed from outside with pliers or the like, deformed, and fixed to the wire 44. Note that the method of fixing the wire is not limited to the above, and it is also possible to weld the resin constituting the bar or use a strong adhesive. Further, a spring 46 as elastic means is interposed between the application section main body 12 and the front bar 14. The spring urges the front bar 14 and the application unit main body 12 away from each other. The elastic means is not limited to a spring, and it is also possible to employ another elastic material capable of exerting a repulsive force against the elastic means when the elastic means is pressed. The lower end of the spring 46 is received in the concave portion 34b of the hole 34, and the upper end thereof is also received in a shallow concave portion provided on the lower surface of the application portion main body 12 as shown in the figure. This prevents the spring from shifting laterally. In addition, each bar can be attached to the application unit main body 12 in the same manner for other holes. In addition, as shown in the figure, it is preferable that two bars are attached to each bar, but the present invention is not limited to this.

[0014]

The wax is applied to the floor using the floor coating machine of the present invention.
When applying a coating liquid such as a detergent or a germicidal liquid, the coating liquid is contained in the tank 6, the lever 10 is grasped, and the coating liquid is dropped from the nozzles 32 and 32 ′ through the hose 8 onto the outer cloth.
Then, after the coating liquid has soaked into the outer envelope, the coater is moved in the advancing direction shown in FIGS. 1 and 2 while gripping the handle while the lower surface of the outer envelope is in contact with the floor. Thereby, the coating liquid is applied to the floor surface.

FIG. 5 to FIG. 7 schematically show the operation when a coating liquid is applied to a floor having irregularities using the floor coating machine of the present invention. As shown in FIGS. 5 and 6, even on a floor surface having unevenness, the action of the elastic means and the action of the unevenness provided on the lower surface of the bar significantly reduce uneven coating as compared with the conventional coating machine. It can be applied in reduced amounts. Further, FIG.
As shown in the figure, even if the floor is slightly sloped,
Uniform application is possible. In addition, the rear bar further corrects for small coating irregularities that may only occur with the front and rear bars. Therefore, the use of the coating machine of the present invention enables uniform coating without skill.

[0016]

As described in detail above, when the coating machine of the present invention is used, even on a floor surface having irregularities or an inclined floor surface,
The coating liquid can be uniformly applied without requiring skill. In addition, since the application liquid is impregnated into the outer cloth and applied, the consumption of the application liquid is much smaller than the case where a mop is used.
