Description

[Detailed Description of the Invention] The present invention relates to a hinge mounting groove excavating jig that enables a trimmer to excavate a hinge groove in the mounting surface of a fitting such as a door.

Generally, when attaching a hinge to a door or other fitting, a groove is dug in the mounting surface, but conventionally, trial production is done manually using a chisel, which is uneconomical as it requires effort, time, and skill. There was a drawback.

The purpose of this invention is to eliminate this drawback by using a wood trimmer, which is a power tool for woodworking, to cut holes and grooves on the surface of wood, to easily create grooves for inserting hinges.
The object of the present invention is to provide a jig that enables rapid excavation.

An example of the implementation of the present invention will be described below with reference to the drawings. First, a woodworking trimmer will be briefly described.

FIG. 1 is a perspective view showing a wood trimmer, in which you hold the body 33 and move the base 32 while pressing it against the surface of the wood.
As shown in the figure, holes and grooves are excavated by scraping the surface of the wood with a pit 34 that rotates at the tip.

3 to 5, the present invention includes a frame 1 formed into a substantially rectangular shape, a fastening tool 6 for fixing the frame 1 itself to a fitting such as a door, and two rectangular frames whose positions can be freely adjusted. It consists of guide plates 2 and 4.

The short side members a and a' of the frame 1 are constructed so as to rest on both ends of the upper surfaces of the long side members s and b', so that the upper surfaces of the long side members s and b' are aligned and form one plane.

The tightening tool 6 has an angle shape, and both sides of one side of the fastening tool 6 are slidably fitted into guide grooves 8, 8 formed by arranging angle-shaped protrusions 7, 7 in opposition to each other on the upper surface of the sap material. , the other side is facing downward.

In addition, a bolt 10 screwed into a nut 9 buried in the center of the sapwood is inserted at right angles into the center of the sapwood, and the tip of the bolt 10 is rotatably attached to the back of the fastener 6. The tightening tool 6 moves forward and backward as the bolt 10 rotates.

Next, one guide plate 2 is placed on the upper surface of the tightening tool 6, and is fitted between the edges of both protrusions 7, 7, and is guided by the edges and perpendicularly to the long side material. Sliding.

The other guide plate 4 is placed on the upper surface of the short sapling a, and has two long grooves 11 carved on its lower surface that are fitted into two protrusions 11' on the short sapling a, respectively. It slides along the long side material b'.

Elongated holes 12.14 are formed in both the guide plates 2 and 4 in the sliding direction, and each of the elongated holes 12.14 is inserted into the tensioning device 6 and the elongated side material 6', respectively. Bolts 15° and 17 are inserted, and wing nuts 1 are inserted into each port T-15 and 17.
8°20 screwed together.

Therefore, both guide plates 2 and 4 can be freely positioned on the tightening tool 6 and the long side material H by tightening the guide plates 18.20.

Guide walls 3 and 5 having a predetermined height are erected in parallel with the guide plates 2 and 4, respectively, on the outer edge of the upper surface of the long side material and on the inner peripheral surface of the short side material a'.

Further, a long relief groove 13 having a slightly wide width is cut on the inside edge of the upper surface of the long side material.

A reference line 17 is displayed on the side of the trial product 13 at a predetermined interval (interval dimension A to be described later) from the guide wall 5, and a scale 19 is displayed from the reference line 17 toward the guide plate 4.

On the other hand, there is also a reference line 21 for the guide plate 2 on the upper surface of the tightening tool 6.
and scale 22 are displayed.

Note that a clamping part 3' that clamps the fitting 23 in cooperation with the advancing fastener 6 is provided on the lower surface of the long side member b'.

A method of using the accommodation device of the present invention having the above configuration will be explained.

In advance, ink 24 indicating the position of one side of the hinge is placed at the attachment location of a fitting 23 such as a door where the hinge is to be attached.

As shown in FIGS. 3 and 5, with the reference line 17 aligned with the ink 24 drawn in advance, insert the fitting 23 between the long side pieces and b', tighten the bolts 10, and tighten the fasteners. 6 to frame 1 and fittings 2
Fixed at 3.

Next, the guide plates 2 and 4 are aligned with the reference line 17.21 and the scale 19.
．． 22, slide it to a position that matches the dimensions of the hinge mounting groove 25 to be excavated, and inspect it using the hinge nut) 18.20.

The positioning dimensions C and D of the guide plates 2 and 4 are, as shown in imaginary lines in FIG. It is determined by the relationship between the width D2 and the width D2 of the fitting 23.

More specifically, when excavating the hinge mounting groove 25 with length B and width, dimension C is A+B and dimension D2-D.
Each is set by l.

However, in this case, when the rear edge of the guide plate 2 follows the reference line 21 on the fastener 6, the distance from the front edge, that is, the guide surface, to the side edge of the fitting 23, that is, the tightening surface of the fastener 6, is A. However, if you do this, no matter how the width n of the fitting 23 changes, the width of the tightening tool 6 at any point before or after fixing the jig to the fitting 23 will be equal to By moving the guide plate 2 above and setting the dimension D=D, D1, the width D1 of the hinge mounting groove 25 can be easily determined.

Thereafter, as shown in FIG.
, 5 into the inner space of the base 32, and the lower surface of the base 32
3 and the long side material 3 and b', and while sliding the outer peripheral surface of the base in sliding contact with each guide surface and moving it in a rectangular shape, excavate the hinge mounting groove 25 as planned with the bit 34 of the trimmer 31.

At this time, the escape groove cut into the long side material b' acts so as not to prevent the bit 34 from excavating up to the edge of the fitting 23.

As described above, according to the present invention, a hinge mounting groove can be easily, quickly, accurately and neatly excavated using a wood trimmer.

The tightening tool is equipped with a gyneid plate that can be slid freely on it and a scale for dimensioning, and it is possible to easily measure only during dimensioning regardless of whether the jig is fixed to the fixture before or after fixing it, and the trimmer can be moved easily. Since it is surrounded by the quid surface on all sides, crabs and the like will not jump out at any point, making it safe to work with.

In addition, the adjustable guide plate on the fastener, which cooperates with the fixed clamping part to clamp the fixture, is not directly involved in clamping the fixture, but only has the function of guiding the jig. The scale and guide part do not need to be very strong, the structure can be simplified, and there are no restrictions on material control, which is effective for downsizing and reducing the number of rotors.

Furthermore, if the frame and guide plate are individually molded from hard synthetic resin, mass production will be possible.
