Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable electric planer capable of finishing a surface to be cut into a substantially perfect plane.

[0002]

2. Description of the Related Art An example of a conventional portable electric planer will be described with reference to FIGS. The portable electric plane has a built-in electric motor (not shown), a handle 13 provided with a switch 14 for driving the electric motor, and a main body 1 provided with a cutter block portion 8 which is rotated by driving the electric motor and to which a planer blade 3 can be attached. And a front base 12 located at a lower front part of the main body 1 and a base 10 located at a lower rear part. The cutter block 8 is provided between the front base 12 and the base 10, and the front base 12 is vertically movable with respect to the bottom surface of the base 10. The amount of cutting can be adjusted.

[0003]

As shown in FIGS. 6 and 7, a planer blade 3 is provided by the above-mentioned conventional portable electric planer.
When the workpiece 2 having a width larger than the width of the workpiece 2 is cut, a step 4 due to the uncut portion is generated on the upper surface of the workpiece 2 as shown in FIG. When trying to cut this step 4, the only surface that contacts the bottom surface of the base 10 is the step 4.
When the width of the step 4 is small, the main body 1 tilts without being stabilized during cutting, and it is difficult to finish the upper surface of the material 2 to be cut into a flat surface. An object of the present invention is to eliminate the above disadvantages,
An object of the present invention is to provide a portable electric planer capable of finishing an upper surface of a workpiece to a substantially flat surface even if a step due to uncut portions occurs on the upper surface of the workpiece.

[0004]

The above object is achieved by providing a guide ruler at the front of the main body, the bottom of which is smaller than the cutting width of the planer blade, the bottom of which is located on the same plane as the base bottom.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the portable electric planer of the present invention will be described with reference to FIGS. Note that the configuration other than the fixing bolt 7 and the guide ruler 9 located in front of the main body 1 is the same as that of the related art, and thus the description is omitted. As shown in the figure, a fixing bolt 7 and a guide ruler 9 are provided in front of the main body 1. Although not shown, an insertion hole for fitting with the fixing bolt 7 is provided in front of the main body 1. Information ruler 9
Has a configuration having a hole 9a, a bottom surface 9b, and a relief portion 9c as shown in the figure. The hole 9a has an inner diameter slightly larger than the outer diameter of the fixing bolt 7, and through this hole 9a, the fixing bolt 7 fits into an insertion hole of the main body 1 to attach the guide ruler 9 to the main body 1. . The position of the hole 9a is adjusted such that the bottom surface 9b provided below the guide ruler 9 is located on the same plane as the bottom surface of the base 10. By providing the escape portion 9c, it is possible to get over a convex portion or the like existing on the upper surface of the workpiece 2.

If a step 4 occurs due to uncut portions on the upper surface of the workpiece 2, a guide ruler 9 is attached to the front of the main body 1, and cutting is performed with the bottom surface 9 a of the guide ruler 9 placed on the upper surface of the workpiece 2. . At the beginning of cutting the step 4, the main body 1 is guided by the bottom surface 9a of the guide ruler 9, and thereafter the bottom surface 9a of the guide ruler 9 is located on the same plane as the bottom surface of the base 10. Since the main body 1 is supported on the work material 2 by the bottom surface 9a, the step 4 can be cut in a state where the main body 1 is stable, and the upper surface of the work material 2 can be easily made almost flat. Will be able to

During normal cutting, the fixing bolt 7
It is necessary to loosen the guide ruler 9 so that the guide ruler 9 does not protrude from the lower surface of the front base 12 by rotating the guide ruler 9 with the hole 9a as a fulcrum, or to remove the guide ruler 9 from the main body 1. In the above embodiment, the guide ruler 9 is provided with the hole 9a having an inner diameter slightly larger than the outer diameter of the fixing bolt 7, but the slot 9d as shown in FIG. It is good also as composition provided with notch 9e. The guide ruler 9 shown in FIG. 4 can be positioned so as not to protrude from the lower surface of the front base 12 by loosening and moving the fixing bolt 7 upward, and the guide ruler 9 shown in FIG. It can be attached and removed with just a slight loosening. In the above embodiment, the guide ruler 9 has a base 10 at the bottom.
Although the bottom surface 9a positioned on the same plane as the bottom surface is provided, the bottom surface may not be a surface. Any structure provided may be sufficient, and the step 4 can be cut in a state where the main body 1 is stabilized.

[0008]

As described above, according to the present invention, a guide ruler is provided in which the width of the bottom is smaller than the cutting width of the planer blade at the front of the main body and the bottom is located on the same plane as the bottom of the base. Also, even if a step due to uncut portions occurs on the upper surface of the workpiece, a portable electric planer capable of finishing the upper surface of the workpiece to a substantially flat surface can be provided.
