Abstract

PURPOSE:To permit easy attaching and detaching of a roller brush by fitting the core of the roller brush to a cylindrical holder fixed to a press-feeding pipe and tightly fitting the bore of the core onto a piston ring-like rotary ring. CONSTITUTION:This invention relates to the press-feeding roller of a hand roller type to be used for painting of buildings, etc. The cylindrical holder 2 is fixed onto the outside of the press-feeding pipe 1 and a paint discharge groove 8 is provided to one side of the holder 2. The piston ring-like rotary rings 10 in common use as sealing materials having the outside diameter at which the top end faces project slightly from the plane of the holder 2 are embedded into annular grooves 9 inscribed on both the outside peripheries. The roller brush 11 are inserted and fixed onto such rings 10. Then, the attaching and detaching of the roller brush are made easy; in addition, the smooth rotation of the brush is assured and the leakage is prevented by the good sealing function.

Description

DETAILED DESCRIPTION OF THE INVENTION [Fields of application for industrial products] The present invention relates to a hand-roller-type pressure-feeding roller used for architectural painting and the like.

2. Prior Art> In a pressure roller with a paint passage formed by drilling holes in the core of a commonly used roller brush for hand rollers, the roller rotating shaft and its holding means were developed in the 1970s.
The coating system of Japanese Patent Publication No. 2-16097 has a structure that rotates around the outside diameter of the paint introduction pipe like the roller, and the roller is held by a flanged roller that is fixed with a screw. For this reason, the swelling of the core makes it difficult and difficult to remove the roller brush, and it is also difficult to clean the inside of the core. Moreover, since a collar of about 3 mm was exposed on the outer periphery of this core (because the roller was fixed by the collar), the collar interfered and corner painting was not possible.

<Problems to be Solved by the Invention> In view of the above-mentioned circumstances, the present invention aims to provide a pressure-feeding roller in which a roller brush can be easily attached, the inside of the core can be washed, and corner painting can be performed. This is what I did.

Means for Solving the Problems> The present invention provides a paint pressure roller that supplies paint from the inside of the roller brush by a paint pressure pipe inserted into the center of the roller brush, in which the core of the roller brush is disposed outside the pressure pipe. A cylindrical holder into which the inner diameter is inserted is fixed, an annular groove is formed near both ends of the holder, a rotating ring is fitted therein, a roller brush is inserted and fixed on the outside of the rotating ring, and a roller brush is inserted and fixed on the outside of the rotating ring. A paint discharge groove communicating with the holder is formed in the longitudinal direction on the outer periphery of the holder, and the rotating ring has an outer diameter slightly larger than that of the holder, and the outer periphery has an arcuate or chamfered sliding surface. It is arranged.

Due to the above structure, when the roller brush is pressed against a wall surface by grasping the handle provided at the base of the pressure pipe, the roller brush is held by its core using the tension of the rotating ring. Since it is rotatable and rotates smoothly, it has a perfect sealing function and does not cause paint to leak between the holders. In addition, since the holder is installed recessed from the surface of the roller brush, the end of the roller brush can reach the corner (part of the corner) of the object to be coated, thereby preventing uncoated parts.

<Example> Hereinafter, the present invention will be described in detail based on the drawings of the example.

1 is a pressure pipe bent in a U-shape with a grip part (not shown) disposed at the base, and the shaft hole 3 of the cylindrical holder 2 is fitted into the straight part of the pressure pipe 1, and The holder 2 is a fixture 5 that is attached to the fitting base of the pressure pipe 1 with screws 4.
It is fixed with screws. Further, one side of the holder 2 has a longitudinal slit-shaped paint discharge groove 8 that passes through the outflow hole 6 of the pressure pipe 1 and the holder inflow hole 7, and has a paint discharge groove 8 in the form of a longitudinal slit. A piston ring-shaped rotary ring 10 that also serves as a sealing material and has an outer diameter such that at least its tip slightly protrudes from the surface of the holder 2 is embedded in an annular groove 9 carved on the outer periphery. Both ends of the core 12 of the roller brush 11 fitted on the outer periphery of the holder 2 are tightly fitted to ensure sealing of the paint on the side of the paint discharge groove B and smooth rotation of the core 12.

In this case, the shape of the contact surface of the rotary ring lO in contact with the inner diameter of the core may be a chamfered portion 13 disposed on the end edge, a tapered surface 14, an arcuate surface 15, or a tapered surface 14 as shown in FIGS. Alternatively, the cross-sectional shape of the circular surface 16 is adopted. In addition, this rotating ring 1G
The groove fitting is facilitated by joining step cuts 17 provided at appropriate positions in the annular direction.

Next, when using this pressure roller, paint is first introduced into the pressure feed pipe 1 from a paint pressure pump (not shown) disposed separately, and passes through the outflow hole 6 and the holder outflow hole 7 to the holder 2. The paint flows into the paint discharge groove 8, and the longitudinal direction mll front groove 8
It accumulates across the width. In this state, when the roller brush 11 rotates in contact with an object to be coated such as a wall surface, the paint seeps into the roller brush 11 from the ejection holes 18 of the core 12 that sequentially rotates and faces the ejection groove 8 section. The brush bristles 11a are impregnated with a large amount of paint, resulting in even coating.

In this case, the structure for mounting the roller brush 11 is the holder 2.
In other words, since the holder 2 is in a position flush with the roller brush 11 or in a recessed position, the end of the roller brush 11 is located at a corner of the object to be coated (for example, a part of a corner of a wall). It evenly spreads over the entire area and prevents unpainted areas. In addition, since the rotating ring 10 is inserted into both ends of the core 12, the remaining paint inside the core 12 after painting is removed from the rotating ring 10 when the core 12 is removed.
0 can be scraped off. Of course, since this rotating ring 10 is in close contact with the core 12, it naturally also has a sealing function.

<Effects of the Invention> As described above, in the pressure feeding roller of the present invention, the core of the roller brush is fitted into the cylindrical holder fixed to the pressure feeding vibrator, and the inner diameter of the core is arranged at both ends of the holder. Since the mechanism is tightly attached to the piston ring-shaped rotating ring, the roller brush can be easily attached and removed.

That is, the core part is not fixed with screws or the like, and is supported by the tension of the rotating ring, so that it can be easily moved by simply sliding it. Furthermore, since the rotating ring moves along the inner diameter of the core when the roller brush is removed, residual paint can be discharged at the same time. Since the remaining paint is on the outer periphery of the holder, it can be easily cleaned with a brush, etc. Further, during use, paint may accumulate on the rotating ring portion, which may impede the movement of the roller brush, but it can be easily cleaned by removing the roller brush. Moreover, since the end of the roller brush and the end of the holder are flush (or flat), it is easy to coat every corner.
