Abstract

(57) [Abstract] [Purpose] The present invention relates to a template guide for a portable electric router, and an object thereof is to prevent tilting of the main body due to a step between the base and the template guide that occurs when copying the portable electric router. However, it is to provide a template guide that is inexpensive and can perform accurate work. [Configuration] Around the cylindrical portion 6 of the template guide 1,
When the template guide 1 was attached to the base 3 of the portable electric router, the convex surface 10 was provided to be substantially level with the bottom surface of the base 3. As a result, even in the cutting work on the corner portion of the template 2, the portable electric router can be stably held without tilting.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a template guide for a portable electric router.

[0002]

[Prior art]

 An example of the conventional template guide 1 will be described with reference to FIGS. The template guide 1 uses a template and a copy template 2 and is used when a large number of objects having the same shape are processed by a portable electric router. The mounting method of the template guide 1 and the shape of the template guide 1 are shown in FIGS. There are mainly two ways to attach the template guide 1, and the shape of the template guide 1 also changes depending on the attachment method. The method of attaching the template guide 1a shown in FIG. 4 is a method of fixing it to the base 3 of the portable electric router with the attaching screw 4. As shown in the figure, the template guide 1a has a simple shape including a screw mounting surface 8 and a cylindrical portion 6 which comes into contact with the template 2 and serves as a guide.

The template guide 1b shown in FIG. 5 is attached by screwing a male screw provided on the outer shape of the template guide 1b into a screw to be installed on the inner periphery of the central hole of the base 3 and fixing the screw. In the method of FIG. 5, both the base 3 and the template guide 1b need to be screwed, and since they are screwed together, the template guide 1b and the abutting portion 9 of the base 3 are required, and the template guide 1a of FIG. It is a structure that requires complicated machining compared to

[0004]

[Problems to be solved by the device]

 The structure of the template guides 1a and 1b in the above-mentioned conventional technique has the following drawbacks. The template guide 1a shown in FIG. 4 has a simple shape, so that an inexpensive template guide 1a can be provided. On the other hand, in order to prevent the head of the mounting screw 4 from traveling below the bottom surface of the base 3, the bottom surface of the base 3 and the screw can be used. It is necessary to provide a step difference f with the mounting surface 8, and the template guide 1a has a structure that does not contact the upper surface of the template 2. In such a structure, since the base 3 or the template guide 1a is not in contact with the upper surface of the template 2 in the vicinity of the router bit 7, a portable electric tool is used for cutting a corner portion of the template 2 such as the portion A of FIG. As shown in FIG. 6, the tool tilts and may damage the wood 11 or the like, which is a work material, and waste it. Further, in the template 1b of FIG. 5, since the bottom surface of the base 3 and the bottom surface of the template guide 1b contact the template 2 on substantially the same surface, stable cutting work can be performed, but complicated processing as described above is required. The structure has a new drawback that it becomes expensive. An object of the present invention is to solve the above problems and to provide a template guide which is inexpensive and enables accurate cutting work.

[0005]

[Means for Solving the Problems]

 The above object is achieved by providing a convex surface that is flush with the base bottom surface around the cylindrical portion of the former template guide of the prior art.

[0006]

[Action]

 In the template guide of the portable electric router configured as described above, a convex surface having the same height as the bottom surface of the base is provided around the cylindrical portion, and the convex surface contacts the upper surface of the template near the router bit. It can support a portable electric router stably.

[0007]

【Example】

 One embodiment of the present invention is shown in FIGS. The template guide 1 of the present invention has a screw mounting surface 8 for fixing it to the base 3 of a portable electric router by a mounting screw 4, a cylindrical portion 6 which comes into contact with the ten plate 2 and serves as a guide, and around the cylindrical portion 6. It is composed of a convex surface 10 provided at substantially the same height as the bottom surface of the base 3. As shown in FIG. 1, when the template guide 1 is fixed to the base 3 of the portable electric router with the mounting screws 4, the bottom surface of the base 3 and the convex surface 10 of the template guide 1 are at substantially the same height. Since it is formed, it comes into contact with the upper surface of the template 2. Therefore, even when working on the corners of the template 2, the portable electric router can be stably held without tilting.

[0008]

[Effect of device]

 According to the present invention, since the convex surface of the template guide is provided at substantially the same height as the bottom surface of the base around the cylindrical portion, the convex surface of the template guide comes into contact with the template top surface at the same time as the base bottom surface, so that it is portable near the router bit. Can support electric routers. Therefore, even when cutting on the corners of the template, the portable electric router can perform accurate cutting work without tilting, and since the shape is simple, it is possible to provide an inexpensive template guide.
