Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a cutter for caulking work which is suitable for use in a work for cutting off a coke filled in a window frame, an eaves or the like and an outer wall material such as siding, and a seam between sidings. .

[0002]

[Prior art]

 The surroundings of the window frame, siding, etc. of the structure are filled with caulking to maintain airtightness and watertightness. However, when replacing them, it is necessary to cut off the filled caulking with a blade. Conventionally, large cutter knives were used for this type of work, and caulking filled to a thickness of about 12 mm was cut and removed by moving the cutting edge two or three times along the window frame or siding. doing.

[Problems to be solved by the invention]

 The cutter knife used for the above-mentioned coking cutting work is a large-sized cutter knife widely used for various works such as construction work and woodworking work.The blade is formed in a straight line and the blade part is formed in one blade, It has the following disadvantages. For example, as shown in FIG. 11, when the caulking 53 filled between the window frame 51 and the siding 52 is cut off, the hand hits the window frame 51 even if the cutting edge 54A is applied at right angles to the caulking 53. The cutter knife 54 must be tilted. For this reason, the cutting edge 54A is cut obliquely with respect to the coking 53 (see FIG. 12), and a part of the coking 53 on the window frame 51 side remains without being cut off. It is necessary to insert it, and it takes time to remove the remaining caulking 53A again. In addition, there is also a problem that workability is poor because work is performed so that a hand does not touch the window frame 51.

[0004] The above-mentioned problem also occurs when, for example, performing work on corners of a wall bent into an L shape. As described above, when the coking 53 is cut off, the window frame 51 and the siding 52 are damaged due to the cutting with three cutting edges, and the repetitive work is often performed because the cutting operation cannot be performed at once, resulting in poor work efficiency. There is. In addition, since the cutting edge 54A of the cutter knife 54 is manufactured to have a hardness such that the cutting edge can be broken each time when the cutting performance deteriorates, the cutting edge bends during use and faces outward to be used as the window frame 51 or the siding. There is also a problem that the S.52 is damaged. However, a dedicated cutter suitable for the caulking operation has not been proposed.

[0005] The present invention has been made in view of the above-mentioned unsolved problems of the prior art, and is not affected by a work place such as a window frame or a corner of a wall, and is located on a left side, a right side or a right side with respect to a cutting position. To provide a caulking cutter that can be cut easily from either the upper or lower direction and is excellent in workability, and that can cut off the coking quickly and cleanly. With the goal.

[0006]

[Means for Solving the Problems]

 Means of the present invention configured to solve the above-described problem includes a handle, and a cutter blade protruding in a length direction from a tip of the handle, and the cutter blade is attached to the handle. A base, a blade body protruding from the base in a direction perpendicular to the longitudinal axis of the handle, and a blade formed on one side of the trailing edge of the blade, the blade tip of which is inclined with respect to the axis of the handle. The cutter blade comprises a pair of single-blade portions, and the cutter blade is formed in the base so as to be inclined in a substantially rectangular shape with respect to the axis of the handle.

[0007] Each single blade portion of the cutter blade may be formed in a curved shape having a concave blade surface side, so that the blade edge can be applied at right angles to a window frame or siding.

The cutter blade may be inclined with respect to the axis of the handle by forming the blade edge in a concavely curved shape. By doing so, the cutting resistance applied to the cutting edge can be reduced, and the workability and finish can be improved.

[0009] The cutter blade may be inclined at an angle of about 10 degrees with respect to the axis of the handle at the base, so that the problem of a hand hitting a window frame or a wall can be solved.

[Embodiment of the invention]

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the figure, reference numeral 1 denotes a handle. The handle portion 1 is made of a wooden body having a substantially elliptical cross section like a handle portion of a known hand tool such as a hammer, and a notch for inserting a cutter blade 2 to be described later is provided at the distal end 1A. (Not shown).

Reference numeral 2 denotes a cutter blade made of steel inserted into the tip of the handle 1. Reference numeral 3 denotes a base constituting the cutter blade 2. The base 3 is formed of a flat plate piece having a length. The front end side is inserted into the cut of the handle 1 along the longitudinal axis A-A. I'm wearing it. Reference numeral 4 denotes a blade integrally formed on the distal end side of the base 3. The blade body 4 has a substantially trapezoidal shape so as to protrude in a direction orthogonal to the axis A-A of the handle 1, and has a linearly formed distal edge 4 A and a rearwardly extending end from both ends of the distal edge 4 A. It has a pair of soles 4B and 4B that are inclined to open. Reference numerals 5 and 6 denote a pair of single blade portions formed on the rear side edge of the blade body 4. The one-sided one-blade portion 5 and the other-sided one-blade portion 6 are composed of one blade having blade surfaces 5A, 6A formed on one side surface 4C of the blade body 4 from the rear end of each of the blades 4B to the base 3. 5B and 6B are formed in a curved shape depressed toward the front edge 4A. The single blade portions 5 and 6 are formed in a curved shape with the blade surfaces 5A and 6A being concave. The cutter blade 2 having the above-described configuration bends the base portion 3 in a substantially rectangular shape so that the blade body 4 is inclined at an angle θ of about 10 degrees with respect to the axis A = A of the handle portion 1. .

Reference numerals 7 and 7 denote nails for fixing the cutter blade 2 to the handle 1, and reference numeral 8 denotes a mouthpiece fitted and fastened to the handle 1 for holding the cutter blade 2.

The caulking cutter according to the present embodiment has the above-described configuration. Next, a method of using the cutter will be described. In the following description, the worker is right-handed and works with his right hand. FIG. 6 shows an example in which the caulking 53 filled on the left side of the window frame 51 is cut off, and the operator applies the other side surface 4D of the cutter blade 2 to the window frame 51 to cause the coking 53 to tip the cutting edge 5B. By cutting the side and pulling the cutter blade 2 downward from above, the cutting edge 5B can cut off the coking 53 linearly.

In the above-described cutting process, the cutter blade 2 can move while being in contact with the window frame 51 as shown in FIG. 7, so that the cutting edge 5B can be prevented from meandering. Further, since the cutter blade 2 is inclined about 10 degrees with respect to the handle 1, the hand does not hit the window frame 51, so that the cutting operation can be performed efficiently. Moreover, since the cutting edge 5B is formed in a concavely curved shape to reduce the cutting resistance, the caulking 53 can be cut off smoothly.

FIG. 8 shows a case in which the caulking 53 is cut off from left to right along the eaves 61, and the cutting operation is performed using the one-sided single-blade 5 of the cutter blade 2. FIG. 9 shows a case where the caulking 53 between the sidings 52 is cut off. In this case as well, the cutting operation is performed using the one-sided blade portion 5 on one side of the cutter blade 2.

On the other hand, FIG. 10 shows a case where the caulking 53 filling the upper side of the window frame 51 is cut off. In this case, unlike the above operation, the other side one blade portion 6 of the cutter blade 2 is used. In this case, the other side surface 4D of the blade body 4 can be cut off by using the window frame 51 by using the other side one blade portion 6 instead of the one side one blade portion 5.

When the worker cuts the caulking 53 in the lateral direction in the above description with a left-handed left hand, the operator moves the cutter blade 2 from right to left using the other one-sided blade 6 of the cutter blade 2. Will be. Thus, the cutter according to the embodiment can be used by both right-handed and left-handed persons.
