Description

[Detailed description of the device]

[0001]

[The purpose of the device] [Industrial applications]

 The present invention relates to a roller for uniformly waxing a floor surface.

[0002]

[Prior art]

 It is common to wax the paved floor such as vinyl tile or wood to prevent it from getting dirty. For example, on a floor covered with vinyl tiles, after cleaning and washing, apply a thin layer of wax, dry and then finish with an electric brush or electric polisher. This work must be done preferably monthly, at least every three months, to keep the floor clean.

However, until now, waxing has been carried out by exclusively applying a wax liquid (aqueous emulsion) to the floor surface using a mop, but this method is used to form a wax layer having a uniform thickness. Is difficult to achieve and, as a result, usually results in unsightly uneven coating after polishing after drying. Moreover, a considerable amount of force is required to use the mop, which was so remarkable that a large mop was used to improve efficiency.

[0004]

[Problems to be solved by the device]

 In view of the above situation, the present invention aims to provide a waxing roller for forming a uniform wax layer with relatively small force.

[0005]

[Constitution of device] [Means for Solving the Problems]

 (1) Concept In order to achieve the above object, the present invention provides a waxing roller having a sponge layer made of polyvinyl formal as an outer layer. Hereinafter, various elements constituting the device will be described in terms of items.

(2) Polyvinyl formal (PVF) Polyvinyl formal (PVF) is a resin obtained by incompletely asaturating polyvinyl alcohol with formaldehyde in the presence of an acid catalyst, and is represented by the following general formula. It is a polymer compound.

[0007]

For the purpose of the present invention, it is necessary that the above resin has fine open-cells, and this bubble-containing resin can be obtained by allowing a foaming agent such as AIBN to coexist during the acetalization reaction. . Therefore, in order to mold this into a cylindrical shape, acetalization and foaming may be simultaneously performed inside the donut-shaped mold having a predetermined size. The product roll sponge should have a porosity of around 90%.

According to the knowledge of the inventor, the roll-shaped sponge obtained as described above not only adsorbs a large amount of wasx liquid up to 10 times its own weight, but also has a particularly remarkable characteristic as a wax liquid. It has been found that when the impregnating roller is rolled against the floor, it forms a coating of uniform thickness not achievable with other sponge materials.

(3) Roller The waxing roller according to the present invention is preferably reinforced with a core material made of a suitable rigid material in order to supplement the hardness of the roll made of PVF sponge. In the simplest structure, it is sufficient to fit the cylindrical roll around the cylindrical core material supported by the arms whose both ends are the ends of the handle, but it is more preferable to use the cylindrical sponge. It is fitted on a small-diameter cylindrical support member, and the support member is rotatably supported via a bearing on a central fixed shaft, and a cantilevered handle (handle) is attached to the fixed shaft. Is good. With such a structure, the roller can be rolled with a minimum force, and at the same time, the weight of the roller itself can be reduced. However, the method of attaching the roller to the handle in a rotatable manner is known, and any known method can be arbitrarily adopted. Therefore, such an attaching method itself does not form an essential part of the invention.

(4) Handle The waxing roller of the present invention is configured to be movable back and forth with an appropriate handle, and at this time, the roller itself rotates with respect to the floor surface. For small rollers, it is sufficient to be able to grip with one arm, but for large rollers, it is preferable to have a length that can be gripped with both arms. Metal, especially aluminum pipes, are lightweight and suitable for long-term work. Hard polyvinyl chloride pipes, FRP pipes and the like are also preferable.

(5) Usage and Others The waxing roller of the present invention is such that the roller itself is immersed in the wax liquid, or the roller is impregnated with the wax liquid by an appropriate method, and then the floor surface is rotated. Apply wax solution. Since this work uses rolling, it does not require labor such as mop, and the coating condition is very uniform. When the coating work is completed, remove the sponge roll, wash with water, and dry to prepare for the next work.

If desired, a small wax tank may be attached to the handle to allow small portions of the wax liquid to be delivered to the coating sponge roll either naturally during operation or by manual opening of a valve attached to the tank. May be. In particular, if a squeeze roll is attached separately from the coating sponge roll and the wax liquid is indirectly supplied via the roll, the coating film thickness can be made more uniform.

[0014]

[Action]

The reason why the roller of the present invention enables uniform waxing is not clear, but it is considered that the PVF sponge has appropriate elasticity and the free hydroxyl group of PVF imparts appropriate hydrophilicity to the sponge tissue of the roller. A large amount of wax liquid ( ^o / _W type emulsion) is adsorbed in combination with the large porosity of the tissue (preferably around 90%), and the wax liquid gradually bleeds on the roll surface due to compression deformation that occurs when the wax liquid rolls. It is presumed that it is due to coming out. Therefore, in order to prevent the sponge roll from excessively deforming during rolling, it is an auxiliary condition in the construction of the invention that the compressive deformation in the radial direction is appropriately limited by the rigid support.

Are inserted into the blind holes 5a and 5'a formed along both ends of the blind holes. This waxing roller can be easily assembled by expanding either one of the support members 3 or 3'and inserting the pins 4 and 4'into the holes 5a and 5'a of the core member 5. Disassembly after use may be performed in the reverse order.

Embodiment 2 FIG. 2 is a cutaway sectional view showing another example of the inventive waxing roller, and FIG. 3 is an overall perspective view thereof.
