JPH067870U - Structure of the discharge tube of the cartridge type caulking gun - Google Patents

Abstract

(57) [Abstract] [Purpose] When filling the joints on the boundary between two adjacent surfaces in the interior or exterior of buildings, sheet metal work, etc., the filling material sticks out from the joint line to the left and right, and aesthetically deteriorates. It is an object of the present invention to provide a device capable of being filled correctly along a joint line in order to prevent troublesomeness. [Structure] The operator should constantly position the discharge cylinder in the desired direction so that the cut end of the caulking gun with a tapered circular or rectangular cross section is always in close contact with the joint surface and does not bend to the left or right. Marking lines, protrusions, and depressions are provided above and below the cut surface of the discharge cylinder so that the filling can be performed correctly by easily determining what is done.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a manual cartridge-type caulking gun used for filling a joint between walls, particularly a joint at a corner, with a coating material in construction work or sheet metal work.

[0002]

[Prior art]

 Conventionally, the filling work of joints was putty with a wooden spatula, but in order to improve work efficiency, the use of caulking gun was introduced from about 10 years ago as a painting work to fill inside corners and outside U-cuts. . The discharge tube of this caulking gun has a vertical or circular cross section with a taper shape and is formed integrally with the cartridge body, or is a screw type or a snap-in type, and when used, place it near the tip of the discharge tube. It was cut diagonally with a knife to make an oblong or elongated rectangular cut, and the long one was used parallel to the center line of the joint.

However, during work, the direction of the discharge cylinder is displaced due to vibration, or the working point becomes significantly higher or lower than the eye position, so that the longer diameter of the cross section of the cylinder tip or the direction of the side is left or right. It was difficult to prevent the filling area from becoming jagged due to runaway. Therefore, it was necessary to finish the filling for a relatively short distance, confirm the direction of the cut cross-section again, and restart the work, which markedly hindered the work efficiency.

Especially for beginners, when the filler adheres to the tip of the caulking gun, the radial direction becomes unclear, and the filler can be filled only so as to bulge out from the joint, and the protruding portion can be covered with a waste cloth. It had to be wiped off, and when the filling work was performed from the right side and then moved to the left side, the directionality deteriorated, the linearity was easily lost, and the work efficiency decreased.

[0005]

[Problems to be Solved by the Invention] When using a caulking gun to fill the corners with synthetic resin or the like, the oblong or elliptical rectangular cut end of the discharge tube is vertically arranged so that it becomes long. The cartridge-type caulking and the cartridge-type caulking gun are often loosened during the work, and the cross section of the discharge tube may move to the left and right with respect to the center of the joint, which is unnecessary. It was often the case that the filler was adhered to various places and the finish was poor. Since the gun was moved while pressing it against the wall with a considerably strong force, it was difficult to recognize the deviation between the left and right during the work.

[0006]

[Means for Solving the Problems]

 Not to mention the case where the device is integrated, in the case of the detaching method, the outside of the discharge cylinder is used to grasp from the outside whether or not the major axis direction of the cut cross section matches the target line. If the linear or dotted line mark was colored or the tube was provided with irregularities, the deviation could be determined and the joint could be filled in a substantially linear shape.

[0007]

【Example】

 In a detachable discharge cylinder made of synthetic resin with a circular cross section (length 100 mm, root diameter 20 mm), a black line with a width of 1 mm from the root to the tip was colored, and the opposite side (180 ° on the circumference) Position) with another similar line. Prior to use, the tip is cut off with a knife so that the long axis end of the ellipse is on the line of the mark, and the long axis end is moved along the center line of the joint to discharge the filling material, resulting in a linear filling. Made possible.

In addition, regarding a discharge tube having a rectangular cross section made of synthetic resin (the base portion is circular, the length is 70 mm, the tip width is 4 mm, the width is 12 mm, and the base diameter is 20 mm), two black straight lines are passed through the center of the short side of the rectangle. Prior to use, the part that has been pulled is cut diagonally near the tip to make a long rectangular cross section, and the filling material is discharged while moving the gun with the mark line centered on the joint.

[0009]

[Advantage of the Invention] If the filling work is always performed at the eye level, it is possible to work without sticking to the rotation in the direction of the cut even if the cut of the discharge tube is close to a perfect circle. Above or below the height, the gun must be slanted in order to fit the cut to the wall, and the cross section of the cut must therefore be slanted to continuously discharge the filler. According to the present invention, it is possible to achieve almost perfect work by aligning the mark of the cylinder with the joint line with the long cut end facing up along the direction of travel of the gun in both the up and down and left and right directions. Bring

Since the filler remaining after use is difficult to store for a long period of time, the amount of resin filled in one cartridge is relatively small (about 300 g). At times, it is necessary to use many cartridges with the discharge cylinders replaced, but in each case, the markings on the cylinders have an extremely effective effect in order to prevent displacement in the direction of the cut cross section of the cylinders. .
