This is a diagram showing the operating state of a painting device that facilitates painting.

Referring to FIG. 1, the painting device 100 according to this embodiment includes guide parts 10a and 10b, a gap adjusting part 20, and a roller part 30.

The painting device 100 is a device that is supported on the rooftop of a building or structure and paints the exterior wall while being lifted and lowered by a wire and a motor, and includes a main body 80 whose portion facing the exterior wall is open.

As shown in the drawing, this main body 80 is in the form of connected frames, may be open on all six sides, and may be composed of a plurality of layers, but is not limited to this form. That is, only the part facing the outer wall may be open, or the frame may be connected to the left and right sides to provide more room.

The main body 80 may be a pipe member made of metal or hard synthetic resin, and may be made of a material that provides a certain level of strength and weight reduction.

A pair of guide parts (10a, 10b) are provided on both sides of the main body (80) to face the outer wall, and one end of the guide parts (10a, 10b) is connected to the round bar (21) of the spacing adjusting part (20). , a roller unit 30 is provided at the other end.

The guide portions 10a and 10b adjust the spacing between each guide portion 10a and 10b, which is possible by the spacing adjusting portion 20. The spacing adjusting portion 20 adjusts the distance between the guide portions 10a and 10b. It is provided at once.

This spacing adjusting unit 20 includes a round bar 21 that is rotatable without interference with the guide unit 10, and a holding means 23 that maintains the gap between the guide units 10a and 10b, and the round bar (21) is supported on a support member, such as a support plate (40).

The round bar 21 is supported through brackets 41 provided on the support plate 40, and the brackets 41 are provided on both sides of the round bar 21 to support the round bar 21.

At this time, the bracket 41 must be formed at a height that allows the guide parts 10a and 10b inserted into the round bar 21 to rotate at a certain angle. That is, when the guide parts 10a and 10b rotate, they collide with the support plate 40. The height of the bracket 41 is set so that the guide parts 10a and 10b can rotate as necessary.

In this embodiment, the rotation of the guide parts (10a, 10b) is for painting the outer wall, and since the angle between the guide parts (10a, 10b) and the round bar 21 is not 90 degrees, the guide parts (10a, 10b) The height of the bracket 41 can be formed so that a gap that allows rotation within 90 degrees is maintained.

Each guide portion 10a, 10b has a hole formed at one end, and a round bar 21 is inserted into the hole. At this time, the guide parts (10a, 10b) and the round bar 21 can rotate without interfering with each other. To this end, the first and second bearings 51 are installed between the guide parts (10a, 10b) and the round bar 21. , 52) is provided.

These first and second bearings 51 and 52 have an inner diameter equal to the outer diameter of the round bar 21, and, as in the present embodiment, may be provided inside each guide portion 10a and 10b. .

The first and second bearings 51 and 52 allow the guide portions 10a and 10b to rotate, so that when the outer wall is not smooth, the main body 80 moves along the outer wall even if it moves away from or is pushed away from the curved outer wall.

The first and second bearings 51 and 52 may have jaws formed inside them to prevent the guide portions 10a and 10b from descending further from the main body 80 in a horizontal state.

As for these guide parts (10a, 10b), the distance between each guide part (10a, 10b) in the round bar (21) can be adjusted. That is, the operator can adjust the gap by moving the guide parts 10a and 10b inserted into the round bar 21 to the left and right.

That is, in the general state as shown in FIG. 2A, the gap between the guide parts 10a and 10b can be adjusted by moving the guide parts 10a and 10b left and right as shown in FIG. 2B.

In Figure 2b, the one-side guide part 10a is moved inward to reduce the gap between the guide parts 10a and 10b, and the roller rotation axis 31 becomes loose, and the roller 33 also becomes loose due to the weight and the loose roller rotation axis ( 31), it becomes stretched.

On the other hand, the guide parts (10a, 10b) must be painted with the gap maintained after adjusting the gap, and even if there is no maintenance means, the paint work is carried out due to the weight of the guide parts (10a, 10b) and the roller part (30). It is rare for the time interval to widen.

Here, in order to firmly maintain the gap between the guide parts 10a and 10b, a holding means 23, for example, a snap ring, may be provided on the outside of each guide part 10a and 10b.

When using a snap ring as the holding means 23, in order to further strengthen the guide portions 10a and 10b from moving, a groove into which the snap ring can be inserted can be further formed on the outside of the round bar 21.

Meanwhile, when adjusting the spacing of the guide parts (10a, 10b), both guide parts (10a, 10b) can be adjusted, and the guide part (10b) on one side is fixed and only the guide part (10a) on the other side is left or right. You can also adjust the gap between the two guide parts (10a, 10b) by moving to .
