Description

  The present invention relates to a portable router having a tip tool that can protrude below a base.

  An example of a conventional portable router will be described with reference to FIG.

  As shown in FIG. 1, the portable router includes a housing 1 that houses a motor (not shown), a handle 2 that is detachably provided on the housing body, a tip tool 5 that is detachably attached to the tip of the motor, and a housing 1. The base 3 is provided at the lower portion, holds the housing 1, and has a base 3 having a hole 3a (not shown) through which the tip tool passes.

  In the portable router, the base 3 is placed on the upper surface of the work material, and the base 3 is slid on the work material, thereby cutting the work material with the tip tool. For the purpose of improving, the base 3 is attached with a sub-base 4 formed of resin or the like constituting the bottom surface of the base 3.

When collecting dust generated during cutting work, for example, the dust collecting hose and the dust collector are connected via an adapter having a shape covering the tip tool 4 on the upper surface side of the base 3.
JP 2001-170905 A

  As shown in FIG. 8, the conventional portable router described above is arranged on the upper surface of the workpiece 13 and slides the base 3 on the workpiece to perform a grooving operation or the like. The workpiece 13 is cut with the tip tool 5. In the cut groove 12, cutting waste 14 was accumulated in the cut groove 12.

  An object of the present invention is to provide a portable router with good workability that can solve the above-described problems and suppress the accumulation of cutting waste.

  The above object can be achieved by providing the base with a projecting member that can project from the bottom surface of the base and a biasing means that biases the projecting member in the projecting direction.

  According to the present invention, by providing the base with the protruding member that can protrude from the bottom surface of the base and the urging means for urging the protruding member in the protruding direction, the protruding member is fitted into the cutting groove and cut into the cutting groove. It is possible to provide a portable router with good workability that can suppress the accumulation of waste.

  An embodiment of the portable router of the present invention will be described with reference to FIGS.

  As shown in FIG. 1, the portable router includes a housing 1 that houses a motor (not shown), a handle 2 that is detachably provided on the housing body, a tip tool 5 that is detachably attached to the tip of the motor, and a housing. 1 is configured to include a base 3 that holds the housing 1 and has a hole 3a (not shown) through which a tip tool passes in the center.

  The base 3 is arranged on the upper surface of the work material, and the base 3 is slid on the work material, so that the cutting work of the work material is performed by the tip tool 5. The base 3 is attached with a sub-base 4 formed of resin or the like that constitutes the bottom surface of the base 3.

  When collecting dust generated during cutting work, the base 3 is connected to a dust collecting hose and a dust collector, for example, via a detachable adapter having a shape covering the tip tool 5 on the upper surface side of the base 3. The

  As shown in FIGS. 2 and 3, the base 3 is provided with a sub-base 4 made of resin or the like to improve the slidability of the router, and a hole 3a through which the tip tool passes is provided in the center. It has been. As shown in FIG. 3, the base 3 is provided with a plate 6, which is a projecting member connected via a pin 7, so as to be rotatable about the pin 7. As shown in FIGS. 2 and 3, the plate 6 is always urged in a direction protruding from the lower side of the base 3 by a spring 8 that is urging means. The plate 6, the pin 7, and the spring 8 are stored in a storage portion 3 b formed on the base 3.

  As shown in FIG. 4, a plurality (three) of plates 6 are provided, all of which are configured to be rotatable about a pin 7 housed in a recess 10 provided on the base, with the rotation fulcrum as the number of plates 6. Accordingly, the spring 8 is provided. Thereby, also in the cutting groove by the blade width of arbitrary tip tools 5, only the part fitted with the cutting groove of plate 6 will fit.

  As shown in FIG. 5, the plate 6 has a rounded corner at the portion in contact with the workpiece. Thereby, when the plate 6 is not fitted in the cutting groove, the surface of the workpiece is not damaged, and when the plate 6 is fitted in the cutting groove, the bottom surface of the cutting groove of the workpiece is damaged. There is no structure.

  A state when the plate 6 is not fitted in the cutting groove (when cutting is not performed in the present invention) will be described with reference to FIG. The plate 6 is urged in the protruding direction by the spring 8 and is in contact with the workpiece 13 at a rounded corner.

  The state when the plate 6 is fitted in the cutting groove 12 (when cutting is performed according to the present invention) will be described with reference to FIG. The plate 6 is biased in the projecting direction by the spring 8, fits into the cutting groove 12 cut by the tip tool 5, and is configured to suppress the accumulation thereof to guide the cutting waste 14 in the cutting direction. . Since the plate 6 is biased in the protruding direction by the spring 8, the tip of the spring 8 abuts against the bottom of the cutting groove 14, so that the cutting waste 14 can be cut even at an arbitrary length of the tip tool 5. It is possible to guide in the direction.
