Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a court roller used for leveling the soil surface of a school ground, soft-ball tennis court, etc., to make it firm and smooth. This invention relates to a new coating roller made of stainless steel.

(Prior Art) Conventionally, the roller portion of a court roller used on grounds such as schools, soft tennis courts, etc. has been constructed by molding iron into a predetermined shape.

Further, the shaft portion and handle portion of the coating roller were also constructed by molding iron into a predetermined shape, as shown in the coating water absorber disclosed in Japanese Patent Application Laid-Open No. 59-46984.

Furthermore, the conventional mud remover attached to a court roller has a structure in which the mud removed from the roller cannot be retained in the mud remover.

(Problems to be solved by the invention) However, the conventional court rollers described above are usually left in a corner of an outdoor tennis court space during storage, so they are exposed to rain, etc. As a result, the iron that forms the roller parts of court rollers corrodes, and as a result, the surface of the roller part becomes so-called "uneven" and the surface of the soil at schools, etc. grounds, soft tennis courts, etc. There were problems in that the coating roller could no longer fully perform its role of leveling the ground hard and smoothly, and as a result, its durability was shortened.

Also, as mentioned above, if the iron that forms the roller part of the coating roller corrodes due to rain, etc.,
There was a problem in that the coat roller had a reddish-brown appearance, which made it look unsightly as a piece of equipment placed in a school playground or the like.

In particular, in soft tennis courts, in order to protect the court from frost pillars in winter, it is often done to tighten the surface of the tennis court by sprinkling salt (sodium chloride) on the soil surface of the court. However, the salt (sodium chloride) used at this time oxidizes the iron that forms the roller part of the coating roller, which easily corrodes the surface of the roller part and turns it reddish brown. There was a problem.

Furthermore, if there are pebbles or the like on a tennis court or the like that you are trying to level, if you crush them with a court roller, the strength of the iron that forms the roller part is weak, so this will easily cause the roller part to collapse. There was a problem that dents were formed.

Furthermore, conventional mud removers attached to court rollers were constructed in such a way that the mud removed from the rollers could not be retained in the mud remover. There was a problem that it could not fully demonstrate its original function as a trap.

In addition, the mud remover attached to the conventional court roller is made of iron just like the court roller, so it corrodes and becomes reddish brown, giving it an unsightly appearance. It was hot.

(Purpose of the invention) This invention was made in view of the above-mentioned conventional problems, and includes a roller part, a shaft part inserted into the roller part, and a handle part supporting the shaft part. In the roller for use, each of the roller part, the shaft part, and the handle part is made of stainless steel, so that durability and
An object of the present invention is to provide a coating roller that is highly corrosion resistant and salt resistant, and whose appearance always retains the brightness when manufactured.

In addition, by attaching the mud remover made of stainless steel to the coating roller, it is highly durable and corrosion resistant.Furthermore, the appearance always retains the shine of the manufacturing time, and the mud removed from the roller is used as the mud remover. To provide a mud remover for a coating roller configured so that it can be held.

(Means for Solving the Problems) This invention provides a coating roller having a roller portion, a shaft portion inserted into the roller portion, and a handle portion supporting the shaft portion. The above object is achieved by constructing each of the shaft portion and the handle portion from stainless steel.

Further, this invention achieves the above object by attaching a mud remover made of stainless steel to the coating roller.

Next, the embodiment shown in FIG. 6 will be described.

In this embodiment, a mud remover 31 made of stainless steel is attached to a coating roller 7 whose roller portion 1, shaft portion 3, and handle portion 5 are each made of stainless steel.

The mud remover 31 is formed by cutting a piece of stainless steel rope into an arbitrary shape and bending it into a substantially semicircular cross section, and one end 31A of the stainless steel rope is attached to an arbitrary position of the handle portion 5 by a bolt or the like so that it can be rotated freely. The other end 31B is attached to the roller part 1.
It is configured so as to come into contact with the outer circumferential surface portion 9 of the roller.

The width of the mud remover 31 is configured to be the same as the width in the longitudinal direction of the roller outer circumferential surface portion 9 of the roller portion 1.

The mud remover 31 is biased by a spring member 33 so that the end portion 31B is always kept in contact with the roller outer peripheral surface portion 9 of the roller portion 1.

The end portion 31B of the mud remover 31 is configured to be tapered at its tip so that mud adhering to the roller outer peripheral surface portion 9 can be easily removed.

The spring member 31 is arranged so that even when the removed mud 35 is held in the mud remover 31 bent into a substantially semicircular cross section, the end 31B of the mud remover 31 is connected to the outer peripheral surface of the roller of the roller portion 1. It is configured to have a sufficient biasing force to maintain the state in which it is in contact with 9.

Therefore, in this embodiment, the mud remover 31 is formed by bending the mud 35 removed from the roller outer peripheral surface 9 by the mud remover 31 into a substantially semicircular cross section.
After the court is leveled,
By manually pulling the mud remover 31 strongly in the direction of the handle portion 5, the mud 35 is removed from the mud remover 31.
can be easily scraped out and removed.

In the above embodiment, the mud remover 31
is formed by cutting a piece of stainless steel rope into an arbitrary shape and bending it into a roughly semicircular cross section. However, in the present invention, a mud remover made of stainless steel wire is attached to a coating roller. For example, it may be a mud remover with a concave cross section, or it may be a substantially V-shaped cross section with the fulcrum at any point on the handle portion 5 to which one end 31A of the mud remover is attached. It can also be used as a mud remover by bending two stainless steel ropes into a substantially semicircular cross section so that they are symmetrical about an arbitrary point on the handle part 5 to which one end 31A of the mud remover is attached. It may also be something that forms a container.

(Effects of the Invention) Since the present invention is configured as described above, it has the following effects.

This idea is based on the roller part of the coating roller,
Since the shaft and handle are each made of stainless steel, this court roller is highly durable and corrosion-resistant, and when stored, it can be left in a corner of an outdoor tennis court space. As a result, even if exposed to rain, etc., the parts that form the roller part of the coating roller will not corrode because they are made of stainless steel, and therefore the surface part of the roller part will not corrode. It is said that it can fully perform its role as a court roller, which is to level the soil hard and smooth at school grounds, soft tennis courts, etc., without causing any unevenness. This has excellent effects.

In addition, since it is possible to make a coating roller that is highly durable and corrosion resistant, it is possible to make a coating roller that has a long durable life, and the surface of the roller is always in a so-called "smooth" state. , mud on the court is less likely to stick to it, making it easier to use and
It has the excellent effect of not staining the coated surface.

In particular, when salt (sodium chloride) is sprinkled on the surface of the soil of a soft tennis court to protect it from winter frost, stainless steel is also salt resistant, so it should be used in this case. This has the excellent effect of preventing the roller portion of the coating roller from being oxidized by the salt (sodium chloride).

Furthermore, in this invention, each of the roller part, shaft part, and handle part of the coating roller is made of stainless steel, so that the appearance can always maintain the shine from when it was manufactured. For this reason, the appearance of the coat roller will not turn reddish-brown due to corrosion of the roller part of the coat roller due to rain, etc., and it will always be a silver color as a fixture placed in school playgrounds. It has the excellent effect of retaining its shine and does not impair its beauty.

Furthermore, the strength of stainless steel is 2~2 that of iron.
Because it is 3 times as large, it has an excellent effect that even if there are pebbles on a tennis court, etc. that you are trying to level, even if you crush the pebbles with the court roller, there will be no dents in the roller part. It has the following.

Furthermore, in claim 2, a mud remover made of stainless steel and configured to be able to retain the removed mud in its mud retaining portion is attached to the coating roller, so that the mud removed from the roller is not removed. It has the excellent effect of being able to easily collect mud and fully demonstrating its original function as a mud remover, which is to remove mud from the court.

In addition, as mentioned above, the mud remover is made of stainless steel, so it is highly durable and corrosion resistant.Furthermore, the appearance always retains its original shine, and the mud removed from the rollers can be stored in the mud remover. It has an excellent effect of being able to retain the mud and easily remove the mud.
