SOLUTION: Guide implements 2, 2 are mutually parellely set in a crosswise direction of a base plate 11 so that a motor plane matches a width of a work to cut the wood after fixed. Firstly, the guide implement 2 does not reach a ruler 6, but according to the advance of the cutting, a tip part 22 and a rear end part 23 reach an upper surface 61 of the ruler 6. The guide implement 2 slides on the upper surface 61 of the ruler so that the motor plane forms an excellent cutting surface with a curved surface shape of the wood. In the process of the cutting, the motor plane is prevented from wobbling and sharping unevenness. The wood can simply and excellently be cut and processed to be a recessed surface or a projecting surface without necessitating a skill and a craftmanship and can be combined for a plane cutting.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric plane capable of sharply cutting a curved surface and usable for a flat surface.

[0002]

2. Description of the Related Art Conventionally, a curved plane in which a bottom plate is curved and warped has been exclusively used for cutting a curved surface such as a girder, a shrine building, a gable plate, and the like.

[0003]

However, since the bottom plate is curved, the contact surface between the wood and the bottom plate is small, so that the electric plane is apt to wobble during use, causing problems such as uneven cutting. Thus, it was quite difficult to produce a gable board, etc., even with nervous skills and special skills and skills. In order to improve such problems, Japanese Patent Application Laid-Open No. 7-205
The invention disclosed in Japanese Patent Publication No. 114 has been proposed. However, the invention requires a large bottom plate extending to both sides of the cutting blade, and furthermore, the state of contact between the curved surface of this bottom plate and the curved surface of the upper surface of the side plate differs from place to place. The contact surface between the top surface of the side plate and the bottom plate was reduced, and the drawback of the plane body was still in a state where it could not be eliminated. Also,
In the concave processing, when the degree of concave surface is too tight, the corners of the bottom plate hit the concave surface of the wood, and it was difficult to produce a desired concave product.

The present invention solves the above-mentioned problems, and can cut a concave surface (or a convex surface) of a sled base or a gable plate without necessity, without any skill and skill. The purpose is to provide an electric plane that can also be used together.

[0005]

In order to achieve the above-mentioned object, the gist of the present invention as set forth in claim 1 is that a guide jig projecting downward from the bottom plate on both sides of the bottom plate of the plane body is provided. An electric plane characterized by being detachably mounted parallel to each other in the front-rear direction. Attach the guide jig to both sides of the bottom plate of the plane body, slide the guide jig to a fixed wood suitable for the curved surface shape to be cut and cut the wood, and at the finishing stage, the guide jig will be a regular wood The plane itself is stable because the feet are attached firmly. And even in the case of concave curved surface processing, the bottom plate of the plane body does not have to float on the wood to be cut and does not have to rub the bottom, so that cutting can be performed well. Here, the fixed wood does not need to be as wide as a target product such as a sled base or a gable board, and can be easily manufactured because a thin board is sufficient.

The electric plane according to the second aspect of the present invention is the electric plane according to the first aspect,
The guide jig has a front end located below the rotary blade, a rear end located at the rear of the plane body, and the front end and the rear end protruding downward from other portions. It is characterized by the following. Here, in "the tip is located below the rotary blade", in plan view, the tip of the tip extends beyond just below the rotary blade and extends forward, or the bottom plate after the rotary blade This includes the case where the tip is located in the region near the blade. Almost the same effect,
This is because the effect is obtained. When the leading end and the rear end of the guide jig protrude downward and protrude, two points, the leading end and the rear end, come into contact with the fixed wood even when finishing the wood into a convex shape. Therefore, the belly of the guide jig does not rub against the fixed wood, the electric plane slides on the fixed wood in a stable state, and the cutting operation proceeds smoothly.

The electric plane according to the third aspect of the present invention is the electric plane according to the second aspect,
The outer peripheral edge of the distal end is raised in an arc shape in a side view so that the distance from the axis of the rotary blade to the outer peripheral edge of the distal end is substantially equal. When the outer edge of the tip is raised in an arc shape in side view so that the distance from the axis of the rotary blade to the outer edge of the tip is substantially equal, during the cutting operation, even if the buttocks of the electric plane rise. Also, since the distance from the axis of the rotary blade to the outer peripheral edge is equal, fine finishing can be performed without shaving unevenness.

The electric plane according to the fourth aspect of the present invention is the first to third aspects of the present invention.
Then, the bottom plate of the plane body makes the part after the rotary blade horizontal,
The part before the rotary blade is inclined upward toward the tip, and
It is characterized in that an auxiliary jig for leveling a portion in front of the rotary blade in accordance with a rear portion thereof can be detachably attached to the inclined surface inclined upward. When the bottom plate of the plane body makes the part after the rotary blade horizontal and the part before the rotary blade is inclined upward, even when finishing the wood into a concave shape, the bottom plate does not hit and it cuts well Can be processed. Further, if an auxiliary jig for attaching the bottom plate of the portion before the rotary blade to the rear portion so as to be horizontal is attached, it can be used for a flat surface.

According to a fifth aspect of the present invention, there is provided an electric plane.
The guide jig is provided with a long hole in the width direction, and the distance between the two guide jigs can be adjusted using the long hole so that the guide jig can be attached to the bottom plate of the plane body. If the distance between both guide jigs can be adjusted freely using a long hole so that it can be attached to the bottom plate of the plane body, even if the width of the wood to be curved is variously different, the distance between both guide jigs will be Adjustable for easy handling.

The electric plane includes a plane main body 1, a guide jig 2, and an auxiliary jig 3. The plane main body 1 has substantially the same configuration as a known electric plane having a flat bottom surface. However, the portion of the bottom plate 11 before the rotary blade 12 is inclined upward toward the tip to form a slope 11a. Slope 11
The larger the inclination angle θ of “a” is, the more the concave surface with a steep slope can be cut, which is advantageous (FIG. 3). The slope 11a is provided with a screw hole 111 and a concave groove 112 for screwing the auxiliary jig 3 (FIG. 2). A screw hole 1 for attaching the guide jig 2 is provided on a bottom plate 11 b located after the rotary blade 12.
13 are provided. Reference numeral 13 denotes an electric motor, reference numeral 14 denotes a switch for operating the rotary blade 12, reference numeral 15 denotes a handle, reference numeral 16 denotes a screw cock for adjusting the level of the bottom plate portion 11a in front of the rotary blade 12, reference numeral 17 denotes a rubber disk, reference numeral Reference numeral 18 denotes an opening from which shavings K of the plane blow out. These structures are the same as those of a known electric plane, and a detailed description thereof will be omitted.

The guide jig 2 is a strip having a constant width as shown in FIG. Two guide jigs 2 are prepared and attached so as to protrude below the bottom plate 11. Each guide jig 2,
Near both ends of 2, a long hole 21 is provided in the width direction. By inserting the bolt 4 into the elongated hole 21 and screwing it into the screw hole 113, the guide jig 2 is attached to the bottom plate 1 of the plane body 1.
1 are attached to both sides of the plane body 1 in a longitudinal direction in the front-rear direction of the plane body 1 and are detachably attached to each other in parallel with each other. By providing the long hole 21, each of the guide jigs 2 can be freely adjusted in the width direction with respect to the bottom plate 11 of the plane body 1 (arrow in FIG. 5), and is adjusted to the width Z of the wood M to be cut. (FIG. 6), the distance L between the two guide jigs can be appropriately selected and fixed to the bottom plate 11 (FIG. 5). Specifically, the distance L between the two guide jigs
After setting the bolt, the bolt 4 is passed through the elongated hole 21, and the bolt tip portion 41 is screwed into the screw hole 113 of the plane body 1 and tightened. The bolt head 42 abuts on the step 211 in the elongated hole 21. Achieved by being locked.

The guide jig 2 has a distal end portion 22 located below the rotary blade 12, and as shown in FIG.
The tip of 2 covers most (or part) of the rotary blade. Although the effect is somewhat reduced, the tip of the tip portion 22 may be kept at the position of the bottom plate rear portion 11b near the rotary blade 12.
The rear end 23 is located at the rear of the plane body 1. Then, the front end portion 22 and the rear end portion 23 are raised below the bottom plate 11 as shown in FIG. Further, in the present embodiment,
The outer peripheral edge 221 of the distal end portion 22 is raised in an arc shape in a side view so that the distance d from the axis 121 of the rotary blade 12 to the outer peripheral edge 221 of the distal end portion 22 is substantially equal, as shown in FIG. I have. In the conventional electric plane which cuts a curved surface (especially a curved surface wood which expands convexly), the contact surface of the plane main body 1 with the wood M is small, and the plane main body 1 is in an unstable state.
It was difficult to cut while always maintaining a predetermined angle to the wood to be cut. Even a skilled person carelessly plane 1
However, as shown by the white arrow in FIG. However, even if the electric plane is inclined, the electric plane of the present embodiment raises the outer peripheral edge 221 in an arc shape, and
Since the distance from the outer edge 221 to the outer edge 221 is equal, the degree of cutting of the rotary blade 12 does not change.

As described above, the rear end 23 of the guide jig 2 protrudes downward from the bottom plate 11 to which the guide jig 2 is attached. Here, in addition to the main body 23a, the rear end 23 is raised as required. The spacer 23b that can be attached is attached. By preparing the spacer 23b having a changed thickness h (FIG. 7), the rear portion of the plane body 1 can be lifted according to the degree of the concave portion (or convex portion) of the wood M to be cut. When the degree of bulging of the protruding portion of the wood M to be cut is large, this lifting causes the belly 25 of the guide jig 2 and the bottom surface 11 of the plane body to retract (ascend), and the fixed wood 6 (described later) and The wood 25 prevents the belly 25 and the bottom 11 from rubbing. The spacer 23b is provided with a projection 232 that fits into a groove formed at the bottom of the main body portion 23a. Then, the protrusion 232 is fitted into the groove,
By screwing the screw 5 passing through the spacer 23b into the screw hole 234 of the main body 23a, the spacer 23b is integrally fixed to the main body 23a of the guide jig 2.

The auxiliary jig 3 has a board-like portion 31 which can substantially fill a triangular space in a side view formed by a slope 11a of the bottom plate located before the rotary blade 12 and a horizontal surface 11b of the bottom plate located behind the rotary blade 12. As a main part, a roller part 32 is formed on the front side of the disk-shaped part 31 (FIG. 1). Although the roller portion 32 is not an essential element of the auxiliary jig 3, the presence of the roller portion 32 makes it easier to return the electric plane in a cutting operation. The auxiliary jig 3 is detached from the plane body 1 when cutting a curved surface,
It is attached to the plane body 1 when used for a plane. The projection 311, which fits into the groove 112, is provided on the board-shaped portion 31 to facilitate alignment of the auxiliary jig 3 with the plane body 1. The disc-shaped portion 31 is provided with a through hole 312 at a position corresponding to the screw hole 111. After the screw hole 111 and the through hole 312 are aligned, the screw 7 is tightened.
1 corresponds to the step portion 313 of the through hole, and the auxiliary tool 3
a. At this time, as shown in FIG.
The bottom surface 11 of the plane body 1 is a portion 11b behind the rotary blade 12.
And the part before the rotary blade 12 (becomes the bottom of the auxiliary jig 3)
Form an electric plane that forms the same horizontal plane and finishes the cutting of the wood M into a horizontal smooth surface.

Next, a description will be given of a processing procedure and operation for making a square piece of wood into a concave curved surface using the electric plane. First, when the wood M has a desired concave curved surface finish, a fixed wood 6 having a shape corresponding to the concave curved surface is manufactured. The fixed wood 6 is a thin plate having a thickness W
The upper surface 61 has a predetermined concave curved surface (FIG. 9). Since it is a thin plate, it does not require much effort to form a concave curved surface and can be easily manufactured. Wood, plywood or the like is used as the fixed wood 6. A pair of such fixed trees 6 is manufactured.

Then, as shown in FIG. 8, the fixed wood 6 is attached to both sides of a lumber M to be cut (hereinafter referred to as "work"). Since the electric plane cuts the work M so that the outer peripheral edge 221 of the distal end of the guide jig 2 slides on the upper surface 61 formed by the thickness W of the fixed wood 6, the work M is at least the distal end from the cutting blade 122. The fixed wood 6 is attached so that only the distance N to the outer peripheral edge 221 can be secured above the fixed wood upper surface 61. The fixed wood 6 is fixed to the work M using a nail 8 or the like. In FIG. 8, bolts may be provided between the two fixed trees at the place of the fixed tree 6 located below the work (wood). Also, at the time of product, both ends of the work are cut off,
The fixed wood and the work may be fixed by using a screw or the like by using the cut portion. In order to firmly fix the fixed wood 6 and the work M, a reinforcement and a connecting plate may be further used as necessary.

On the other hand, the guide jigs 2 are set and fixed to the bottom plate 11 so that the electric plane according to the present invention matches the width Z of the work M. The guide jigs 2 are attached parallel to each other in the front-back direction of the bottom plate 11 as described above. Thereafter, when the wood M is cut using the electric plane, the guide jig 2 does not reach the fixed wood 6 at first, but as the cutting progresses, the leading end portion 22 and the rear end portion 23 of the guide jig 2 are moved. Reaches the upper surface 61 of the fixed wood. And the guide jig 2 is the upper surface 61 of the wood 6
, And the electric plane flies the shavings K to form a beautiful cut surface of the wood M with a curved shape (FIG. 8). Here, in the shaving process, the front end portion 22 and the rear end portion 23 located at the four corners of the guide jig 2 are in contact with the upper surface 61 of the fixed wood 6, so that there is no fear that the electric plane is roughened. Therefore, no shaving unevenness occurs. Furthermore, in the present embodiment, the distal end outer peripheral edge 221 is a curved surface, and the distance from the axis 121 to the outer peripheral edge 221 is substantially equal. In addition, there is an advantage that a clean cut surface can be formed stably without causing a difference in a cut degree and without unevenness. Then, approaching the final stage, the work M
Reaches a distance N from the cutting edge 122 to the outer peripheral edge 221 of the tip portion, a finished wood product having a desired concave curved surface and smoothness is completed. Note that, at the beginning of cutting, the guide jig 2 is
If it is not in the state, it may be possible that the electric plane is slightly loose depending on how it is used. However, even if there is play, there is no problem since the shaving unevenness in the initial stage is finally removed. The same applies to the case where the wood M is made to have a convex curved surface finish. However, when processing the wood M on a convex surface, as shown in FIG.
It is desirable to cut unnecessary portions MC with a saw or the like.

The electric plane constructed as described above has a rotary blade 12
Since the bottom plate 11a at the front is inclined upward toward the tip, the conventional problem that the bottom plate 11 hits the wood M and cannot be cut well when machining the concave surface is solved. In addition, by shaping the guide jig 2 on both sides of the bottom plate 11, even if the bottom plate 11b behind the rotary blade is flat,
Since the bottom plate 11 floats from the wood M, it does not hinder cutting. Thus, the guide jig 2 is attached to the upper surface 6 of the fixed wood 6.
By sliding 1, a wood product having a desired concave shape (or convex shape) can be easily obtained.
Since the front end portions 22, 22 and the rear end portions 23, 23 are provided, the electric plane can be stably supported by the four-point support and the upper surface 6 of the fixed wood.
It is on 1 and does not rattle. Therefore, unlike the conventional electric plane in which the bottom plate is curved and the handling is unstable, the skill and the skill are not required, and even an amateur can easily perform the curved surface finishing.

Even when the wood M having a convex shape is manufactured, the fixed wood 6 does not rub the belly of the guide jig 2 due to the overhang of the front end portion 22 and the rear end portion 23. Even in the case where the degree of convexity of the wood M is high, if the spacer 23b is attached, the belly of the guide jig 2 can be lifted by that much, and this problem can be solved without difficulty. Furthermore, even raised the butt of the electric planer by fatigue and the like of the operator, since the set substantially equal to the distance between the axis 121 to the outer peripheral edge, finishing degree to directly clean scraping surface M ₁ at a constant To go. On the other hand, if the head of the electric planer is raised, will be the cutting edge 122 is moved away from the timber M, not hurt scraping surface M _1. Thus, any curved surface shape of the uneven surface can be easily worked and finished to a beautiful cut surface. Even in the processing of wood having different widths, the formation of the elongated holes 21 makes it easy to adjust the distance L between the guide jigs, so that it can be easily adapted.

In addition, if the guide jig 2 is detached from the electric plane corresponding to the curved surface and the auxiliary jig 3 is set, the electric jig is changed to an electric plane for plane cutting. Therefore, it is an extremely useful electric plane.

In the present invention, the present invention is not limited to the above-described embodiment, but can be variously changed within the scope of the present invention depending on the purpose and application. The shape, size, and the like of the plane body 1, the guide jig 2, the auxiliary jig 3, and the like are appropriately selected according to the application. In the above embodiment, the guide jig 2 and the auxiliary jig 3 are made of metal. However, wooden or plastic may be used as long as a predetermined strength is obtained.

[0023]

As described above, the electric plane of the present invention can cut wood into a beautiful concave or convex surface without skill and skill, and can be used for flat cutting. It has great effects such as being possible.
