Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting range determination device for cutting a predetermined range to repair a scratch on a wooden floor, for example, and fitting a new flooring into the cut area for repair. is.

In recent years, in Japanese houses, the number of rooms with wooden floors has increased rapidly, rather than the rooms with tatami mats. However, if the floor is a wooden flooring material, for example, the flooring material may be visibly scratched by dropping tableware or electric appliances.

Conventionally, in such a case, floor repair work has been performed by heating a synthetic resin material to make it fluid in order to fill in the scratches on the floor, and then pouring it into the crack openings. However, since the synthetic resin material to be poured has no wood grain and is a single color, it has been possible to recognize that the damaged portion, that is, the repaired portion, has been repaired even if it is small.

Therefore, a portable cutting tool with a cutting blade was used to cut the area around the scratch with the cutting tool, and the cut area was repaired by inserting wood-grain flooring material. It was difficult to match the size and grain of the flooring material, and the cutting work required a high level of skill.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described based on embodiments shown in the drawings.

The figure shows a cutting range determination device 1 of the present invention.
The cutting range determination device 1 of the present invention cuts the surrounding part including the scratch in order to repair the scratch made on the wooden flooring, etc., and then inserts the flooring material of the same quality and equivalent to the cut part. and repair it.

Here, the configuration of the cutting range determination device 1 will be described.
First, the cutting range determination device 1 is equipped with a cutting edge 2 which can move up and down toward the cutting point, rotates when it comes into contact with the cutting point, and cuts to a predetermined cutting depth at the cutting point, and the cutting edge 2. It has a cutting tool 3 with a body 4 that is rotated by a force.

The cutting tool 3 has a cutting blade 2 at its tip and a main body 4 with a motor installed at its rear end. The cutting blade 2 is attached to the chuck opening of the main body 4 with its rear end gripped.
Various types of cutting blades 2 are prepared, and the cutting blades 2 are exchanged according to the cutting location.

The cutting tool 3 is attached to a mounting stand 6 projecting upward from a flat first member 5 .
The mounting stand 6 includes a plurality of holding members 7 erected on the first member 5 and a cutting tool mounting portion 8 provided on the holding member 7 .

That is, as can be understood from the drawing, the cutting tool 3 is attached to the cutting tool mounting portion 8 so that the tip of the cutting blade 2 faces downward in the vertical direction. A plurality of holding members 7 are formed with oscillating portions 9 capable of vertically oscillating the cutting tools 3, and the cutting blades 2 are vertically oscillated within the oscillating range of the oscillating portions 9. configured to allow When cutting is not performed, the cutting tool 3 is held by an elastic member such as a spring member with an upward elastic force.

Here, the cutting blade 2 protrudes downward from the cutting hole 10 provided in communication with the first member 5 and the second member 12, and the depth of cutting for the cutting location is determined and determined. The cutting depth is determined by the oscillating portion 9 .

That is, the swinging portion 9 determines the protrusion width of the cutting blade 2 protruding downward from the cutting hole 10 of the cutting range determination device 1 . A locking member 11 is attached to the oscillating portion 9 so that the cutting blade 2 does not move downward beyond the determined cutting depth. , does not cut deeply at the cutting point.

As can be seen from the figure, the first member 5 is stacked on the second member 12 . Here, the first member 5 and the second member 12 are formed in substantially the same rectangular shape, and the first member 5 is configured to be movable forward and backward, and the second member 12 is configured to be movable left and right. The means for moving back and forth is not limited at all, but as an example, the first member 5 is formed by stacking two members, and between them a rail and a wheel running on the rail are attached to both members. It is conceivable that the upper member of the two members that are attached to and stacked on top of each other is movable in the front-rear direction.

In addition, when the first member 5 moves in the front-rear direction, the first determination member 13 that determines the movement distance is the side surface of the first member 5, that is, the upper member of the two stacked sheets, for example. attached to the side of the

The first determining member 13 has a first starting point 14 at which the cutting blade 2 of the cutting tool 3 placed on the first member 5 starts cutting in the front-rear direction, and a preset cutting distance in the front-rear direction. and a first measuring portion 16 for measuring the actual length of the cutting distance and clarifying the length.

The end point 15 can be moved in the front-rear direction by the length of the first measure portion 16, and can be temporarily fixed at the moved point. Therefore, the cutting distance in the front-rear direction can be adjusted to a relatively long length.

Next, the means for moving the second member 12 in the horizontal direction is not limited at all. However, as a specific example, the second member 12 is also formed by laminating two members, and a rail and a wheel or the like that runs on the rail are attached to both members in the meantime, so that the second member 12 can move freely in the left and right direction. can be considered.

In addition, when the second member 12 moves in the left-right direction, the second determination member 17 that determines the movement distance is the side surface of the second member 12, that is, the upper member of the two stacked members. attached to the side of the

The second determining member 17 has a second starting point 18 where the cutting blade 2 of the cutting tool 3 placed on the first member 5 starts cutting in the left-right direction, and a preset left-right direction. and a second measuring portion 20 for measuring and clarifying the actual length of the cutting distance.

The second end point 19 is also configured to be able to move further in the horizontal direction and to be temporarily fixed at the moved location. Therefore, the cutting distance in the horizontal direction can be adjusted to a certain length.

By the way, confirmation of cutting can be performed by a visible confirmation part 21 provided in the vicinity of the cutting work hole 10 .

The cutting work hole 10 is provided through the first member 5 and the second member 12, and the vicinity of the cutting work hole 10 is largely cut to be hollow. The upper surface of the first member 5 is covered with a visible confirmation portion 21 formed of, for example, a transparent cover that is visible from the outside and has only a hole through which the cutting blade 2 passes.

Then, the inside covered with the visible confirmation part 21, that is, the inside of the first member 5 and the second member is greatly cut and hollowed, and is a work space so as not to discharge the cut material to the outside. Cutting dust is kept in this working space.

In the above, the state of use of the present invention will be described.
Check the degree of scratches on wooden flooring. Then, horizontal and vertical cutting dimensions, that is, front and rear and left and right cutting dimensions are determined. It also determines the depth of cut. Furthermore, determine the direction of the wood grain.

Next, the cutting range determination device 1 of the present invention is installed at the location with the flaw. Then, the cutting distance is adjusted to the determined distances of the front, rear, left, and right cutting ranges. This distance is set using the first determining member 13 and the second determining member 17 .

Furthermore, it is operated to match the direction of the wood grain. That is, inside the visible confirmation section 21, a wood grain direction setting section is provided. The wood grain direction setting portion is composed of a thread-like member, and is provided, for example, adjacent to the cutting edge 2 in the front-rear direction of the first member. By matching the wood grain direction setting portion with the wood grain to be cut, it is possible to easily match the wood grain of the repair member to be fitted into the cut portion after cutting.

After the predetermined cutting range is determined, the cutting blade 2 is moved downward at the determined predetermined cutting point, and the cutting point is cut to the set cutting depth. Further, from that state, it is moved to the left, for example, then moved further upward, and then further moved to the right to cut into a substantially rectangular shape. Next, the cutting edge 2 is moved to cut the inner portion cut into the rectangular shape.

Thus, the above-described cutting operation completes cutting of a predetermined depth and a predetermined range. At that time, a large amount of cutting dust is generated, but this cutting dust is kept in the work space. A vacuum 24 communicated with the working space prevents the dust from being sucked and scattered to the outside.

When the cutting is completed, a cut portion with a predetermined depth is created. A repair pad formed to the same size is used at the cut location. This repair pad is selected from the same material as the cut floor material and is fitted in with the same wood grain direction. Since the repair pad is fixed with an adhesive, a thickness thinner than the cutting depth is used.

In addition, this cutting range determination device 1 can be used not only for repairing floors, but also for repairing wall materials erected in the vertical direction. When repairing the wall material, a solid adhesive material is attached to the bottom surface of the wall material, and the fixed adhesive material is used to attach the wall material to the wall material.
