Description

  The present invention relates to a roller handle set, and more particularly to a roller handle set in which a painting operation and a paint supply amount control can be separately operated with both hands.

  In general, interior and exterior surfaces of buildings such as wall surfaces, bridges, cars, railway vehicles, and ships are painted. There are various methods for painting, but roller painting is a basic painting method. Roller coating can form a uniform coating film, does not contain bubbles and foreign matters, and can be applied while controlling the film thickness. Therefore, it is a method that is widely used from the application of DIY to the painter. Conventionally, roller coating is a method in which a roller is dipped in a liquid paint to adjust the amount of adhesion, and is applied. This coating method has no problem when the coating area is small, but there is a problem that if the coating area is large, it takes time and cannot be efficiently applied. In Patent Documents 1 and 2, an air control valve and a switch are provided between the paint supply device and the handle, an air hose is connected between the air control valve and the switch, and a portable air cylinder is connected from the switch via the air hose. It has been proposed to paint the roller while operating the switch. Patent Document 3 proposes to use an L-shaped gun and supply paint from the outside of the painting roller to the painting roller for painting.

  However, the proposals in Patent Documents 1 and 2 indicate that the flow rate cannot be controlled when the state of the coating surface changes during painting and the flow rate (liquid paint supply amount) needs to be changed because of on / off control by a switch. There's a problem. Furthermore, it is necessary to attach a portable air cylinder to the body, and there is a problem that the overall weight increases. The proposal of Patent Document 3 has a problem that the flow resistance of the paint is increased due to the L-shaped gun, and a problem that the trigger angle is wide and difficult to operate, and the finger to be operated is fixed.

  In order to solve the above-described conventional problems, the present invention provides a roller handle set that can separately operate a roller coating operation and a paint supply amount control with both hands and can reduce the weight.

  The roller handle set of the present invention is a roller handle set including a painting roller, a handle connected to the painting roller by a pipe, and a straight gun having a trigger, and the gun is pumped from a paint supply means. A connecting portion for connecting to a liquid paint supply pipe, wherein the coating roller, the handle and the gun are connected in series; the handle and the gun are connected by a resin pipe; and between the handle and the gun pipe The distance is such that one hand can hold the handle and the other hand can hold the gun, and the coating roller has a hole in the hollow pipe in the center, and liquid paint is supplied to the roller surface from the hole. It is characterized by that.

  In the roller handle set of the present invention, the painting roller, the handle, and the straight gun are connected in series, the handle and the gun are connected by a resin pipe, and the distance between the handle and the gun pipe is determined by one hand. By holding the gun with the other hand at a distance that allows the gun to be held, it is possible to control the supply amount of the paint by operating the gun trigger with the other hand while applying the roller with one hand. Thereby, the roller coating operation and the paint supply amount control can be operated separately with both hands, and the weight can be distributed to both hands, so that the burden on one hand is reduced, and a roller handle set with good work efficiency can be provided. As a result, the burden on one hand is small, the efficiency of the painting work can be improved, the state of the coating surface changes during painting, and the flow rate control is easy even when the flow rate (liquid paint supply amount) needs to be changed. In addition, by using a straight gun, the flow resistance of the paint is small and the trigger angle is small, so the trigger can be operated with a thumb or a finger other than the thumb, reducing the burden on the finger and controlling the amount of paint supplied There is an effect that can be.

FIG. 1 is a schematic perspective view of a roller handle set according to an embodiment of the present invention. FIG. 2 is a schematic explanatory view of an example in which a painting operation is performed by operating a trigger with a thumb. FIG. 3 is a schematic explanatory view of an example in which a painting operation is performed by operating a trigger with another finger. FIG. 4 is a schematic sectional view of the painting roller. FIG. 5 is a schematic explanatory view of a painting operation when a roller handle set of the prior art is used. FIG. 6 is a schematic explanatory view of another prior art roller handle set.

  The roller handle set of the present invention is a roller handle set including a painting roller, a handle connected to the painting roller by a pipe, and a straight gun having a trigger. The coating roller has a hole formed in a hollow pipe in the center, and liquid paint is supplied from the surface to the roller surface to be painted on the object to be coated. As the member on the surface of the roller, known materials such as a fiber raised body, felt, nonwoven fabric, knitted fabric, woven fabric, resin sponge, resin net and the like can be used.

  The handle is connected to the painting roller by a pipe, and the surface is covered with rubber or resin for easy holding. The painter holds this handle in one hand and rotates the roller for painting. The amount of paint supplied is adjusted by a gun with a trigger. When the trigger (trigger) is not pressed by the finger of the hand, the paint is not supplied, and the supply amount of the paint increases as the pressing amount or pressing angle is increased. The gun is connected to a supply pipe of liquid paint pumped from the paint supply means by a connecting portion, and the liquid paint is supplied. Since the present invention is a straight gun, the flow resistance of the paint is small and the angle of the trigger is small, so that the trigger can be operated with a thumb or a finger other than the thumb, reducing the burden on the finger and supplying the paint. Quantity control is possible.

  In the roller handle set of the present invention, the painting roller, the handle, and the gun are connected in series. This simplifies the paint supply line, eliminates wasteful parts that become dead spaces and dirty parts, and reduces the overall weight. The handle and gun are connected by a resin pipe. This allows the handle and gun to move freely.

  The distance between the handle and the pipe of the gun is such that the handle can be held with one hand and the gun can be held with the other hand. Roller painting is possible by hand. Thus, the roller coating operation and the paint supply amount control can be separately operated with both hands. When both hands can be used in this way, one hand can concentrate on roller painting, and the other hand can operate the trigger to control the amount of paint supplied. As a result, the burden on one hand is small, the efficiency of the painting work can be improved, the state of the coating surface changes during painting, and the flow rate control is easy even when the flow rate (liquid paint supply amount) needs to be changed.

  The distance between the handle and the gun pipe is preferably in the range of 30 to 200 mm, more preferably 50 to 180 mm, and still more preferably 70 to 150 mm. This allows the handle and gun to be operated independently and freely. The resin pipe connecting the handle and the gun is preferably a resin pipe with reinforcing fibers or a resin pipe without reinforcing fibers. Such a resin pipe is easy to move and does not restrict the painting work. From the viewpoint of pressure resistance and durability, a resin pipe containing reinforcing fibers is more preferable.

  The weight of the roller handle set of the present invention is preferably in the range of 400 to 650 g, more preferably 425 to 600 g, and still more preferably 450 to 550 g. This range is convenient for painting work. The conventional product exceeded 650 g.

  Next, it demonstrates using drawing. In the following drawings, the same reference numerals denote the same parts. FIG. 1 is a schematic perspective view of a roller handle set according to an embodiment of the present invention. This roller handle set 1 includes a painting roller 2, a handle 5 connected to the painting roller 2 and pipes 3 and 4, a straight gun 7 having a trigger 8, and a resin pipe 6 connecting the handle 5 and the gun 7. And a connecting portion 9 for connecting to a liquid paint supply pipe 10 pumped from the paint supply means. The painting roller 2, the handle 5 and the gun 7 are connected in series. The distance between the handle 5 and the resin pipe 6 of the gun 7 is such that one hand can hold the handle and the other hand can hold the gun.

  As shown in FIG. 2, the roller handle set 1 is used, for example, by operating the trigger 8 with the thumb of the left hand to control the supply amount of the paint while gripping the handle 5 with the right hand and performing roller coating. As described above, the roller coating operation and the paint supply amount control can be operated separately with both hands. For example, the right hand can concentrate on the roller coating, and the left hand thumb operates the trigger 8 of the gun 7 to control the paint supply amount. it can. As a result, the burden on one hand is small and the efficiency of the painting work can be improved. Also, the flow rate can be easily controlled when the state of the coating surface changes during painting and the flow rate (liquid paint supply amount) needs to be changed.

  As another operation method of the trigger 8, as shown in FIG. 3, for example, the trigger 8 is operated with the index finger and the middle finger of the left hand to control the supply amount of the paint, and the handle 5 is gripped with the right hand to perform roller coating. Thereby, the burden on the finger can be reduced and the supply amount of the paint can be controlled.

  FIG. 4 is a schematic cross-sectional view of a painting roller according to an embodiment of the present invention. A large number of holes are formed in the central shaft 19 of the roller, and liquid paint is supplied to the members on the surface of the painting roller 2 from here.

  FIG. 5 is a schematic explanatory view of a painting operation when the roller handle set 11 of the comparative example (prior art) is used. In this example, the handle 15 and the trigger 18 of the straight gun 17 are integrated with each other, and it is necessary to perform painting work while operating the trigger 18 with one hand.

  FIG. 6 is a schematic explanatory view of a painting operation when the roller handle set 21 of another comparative example (Patent Document 3) is used. In this example, the handle 5 and the L-shaped gun 23 are connected in series, and from the supply port 26 of the branch pipe 25 branched from the paint supply pipe 24 outside the paint roller 27 to the paint roller 27. The paint is supplied and painted. The roller handle set 21 has a problem that the flow resistance of the paint is high due to the L-shaped gun, and a problem that the angle of the trigger 22 is wide and difficult to operate, and the finger to be operated is fixed.

Examples will be described below. The present invention is not limited to the following examples.
(Example 1)
A roller handle set 1 shown in FIG. 1 was prepared. The resin pipe 6 was made of nylon fiber reinforced nylon pipe (inner diameter 6 mm, outer diameter 10 mm, length 1200 mm), the length from the painting roller 2 to the lower end of the handle 5 was 400 mm, and the handle 5 was 150 mm in length. The roller handle set 1 weighed 500 g.

  As shown in FIG. 2, the connecting portion 9 of the roller handle set 1 is connected to a liquid paint supply pipe 10 (nylon fiber reinforced nylon pipe (inner diameter 6.1 mm, outer diameter 11.4 mm)). While controlling the opening and closing amount of the trigger 8 with the left hand while controlling the flow rate of the liquid paint being pumped, grip the handle 5 with the right hand and paint the roller.This roller handle set 1 does not get tired even if painting work for a long time, The burden on one hand was small, the efficiency of the painting work was improved, the state of the coating surface changed during painting, and the flow rate control was easy even when the flow rate (liquid paint supply amount) had to be changed.

(Comparative Example 1)
A painting operation was performed using the roller handle set 11 shown in FIG. This roller handle set 11 had a length of 380 mm from the painting roller 2 to the lower end of the handle 15, a length of the handle 15 of 125 mm, and a weight of 660 g. In the roller handle set 11, the handle 15 and the trigger 18 of the gun 17 are integrated, and it is necessary to perform painting work while operating the trigger 18 with one hand. Was big.

(Comparative Example 2)
The roller handle set 21 shown in FIG. 6 was used, and the painting roller 27 was changed to the painting roller 2 shown in FIG. The reason why the painting roller 27 is changed to the painting roller 2 shown in FIG. 1 is that the painting roller 27 is too easy to use and is not a comparative experiment. After the painting work, the roller handle set 21 had an L-shaped gun, and the flow resistance of the paint was about 10% higher than that in Example 1. Also, the trigger angle was wide and difficult to operate, and the finger to be operated was fixed, and as in Comparative Example 1, the fatigue during painting was great.
