Description

[Detailed Description of the Invention] The present invention relates to an improvement of a roll-type coating device that applies paint to a wall of a building by force-feeding the paint onto a roll like a separate cloth.

Recently, brushes have been used as a method of painting walls of buildings, etc., and roller-type products have become popular in order to eliminate unevenness on the applied surface.

Such a roller type applicator supports a roll made of a material like a separate cloth from one side at the U-shaped bend at the tip of a paint outlet pipe that is connected to a tank via a valve mechanism. There are many products that can be supplied into the roll.

However, when using such a coating device, for example, when coating the boundary between a protruding pillar and a wall, the outlet pipe and the valve mechanism must be rotated 180 degrees, making the task troublesome. However, this process has many drawbacks, such as paint falling off and the entire device falling.

For this reason, we tried to solve the above problem by making the lead-out tube that supports the rolls rotatable, but in this case, a relatively strong force was required to press the rolls against a wall, etc. There was a risk that it would rotate uncontrollably.

This idea was devised in view of the above circumstances; a joint member is attached to the proximal end of the outlet pipe, a circular groove is provided on the proximal end surface of the member, and a recess is provided at an appropriate position in the groove, and the interior of the groove and recess is It consists of a sliding ball and a fixed tube with a spring that constantly presses the ball toward the groove, and the fixed tube supports the outlet tube in a rotatable manner, making it possible to rotate the outlet tube etc. smoothly. The circular groove is provided with appropriate recesses (for example, every 180 degrees), so the rotation of the ball can be restricted to a predetermined position by fitting the ball, and even if a relatively strong force is applied during work, the outlet pipe will not erect. It is an object of the present invention to provide a product that is extremely easy to work with and can achieve a uniform coating finish without causing rotation.

Next, one embodiment of the present invention will be described in detail based on the drawings.

Reference numeral 1 denotes a coating roll like a separate cloth, and this roll 1 is rotatably supported on one side by the tip of a hollow outlet tube 2 whose tip side is bent into a U-shape to which paint can be supplied to the center.

The other end of the outlet pipe 2 is connected to the tip of a joint member 3 via a lock nut 4.

This joint member 3 has a through hole 5 in its center that communicates with the outlet pipe 2, a collar 6 is provided at the base end of the joint member, and a circular groove 7 is bored in the lower surface of the collar, and the groove 7 is located at an appropriate position. It has a structure in which several recesses 8 are provided.

Furthermore, a connecting tube 9 is integrally protruded from the base end surface of the joint member 3, and this connecting tube 9 is rotatably connected to the inside of the fixed tube 10.

Although not shown, a ring-like sealing member is provided at the connection between the connecting tube 9 and the fixed tube 10 to prevent the paint passing through each tube from leaking to the outside.

Further, the connecting tube 9 is engaged with the fixed tube 10 by caulking its tip so as not to be pulled out from the fixed tube 10.

On the other hand, an appropriate number of impermeable holes 11 are provided on the distal end surface of the fixed tube 10.
A ball 13 receiving back pressure from a coil spring 12 is fitted into the impermeable hole 11 .

This ball 13 is inserted into the circular groove 7 of the joint member 3.
It is arranged so that its upper part fits in slightly.

Reference numeral 14 denotes a normal valve mechanism, one end of which is fixed to the fixed pipe 10, and the other end connected to a paint tank or a pressure supply device (not shown).

Next, to explain the operation of this device, the paint passes through the valve mechanism 14 under an appropriate pressure, passes through the fixed pipe 10, the connecting pipe 9, and the joint member 3, and is supplied into the roll 1 through the outlet pipe 2. It passes through and oozes out to the outside.

Therefore, by manually operating the valve mechanism 14 and moving the roll vertically against a wall surface, paint can be applied to the wall surface.

Now, when painting areas where the presence of the outlet tube 2 interferes with coating work, such as the boundary between the front pillar and the wall, turn the U-shaped part of the outlet tube 2 180 degrees by hand. .

In this case, a joint member 3 provided at the end of the outlet pipe 2
is rotatably connected to the fixed pipe 10, and since the ball provided on the fixed pipe 10 is fitted into the circular groove 7 provided on the connecting pipe 9, the rotation operation is smooth.
Since appropriate recesses (for example, every 180°) are provided in the recess, rotation of the recess at a predetermined position can be restricted.

By cutting, the presence of the outlet pipe 2 can be easily applied even in such a case.

As described above, the roll-type coating device of the present invention has practical effects such as being able to change the position of the roll as appropriate depending on the situation of the coating, streamlining the work and making the finish beautiful.
