[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass edge cutting cutter used for cutting a plate glass with a small width.

[0002]

2. Description of the Related Art Conventionally, in order to cut a plate glass with a small width, a ruler is placed on the plate glass and held by one hand, and a glass cutter held by the other hand is moved along the ruler to make a cut, I tried to fold the plate glass at the cut.

[0003]

By the way, in the conventional edge cutting method as described above, since the ruler must be pressed so as not to move, it is difficult to perform the cutting work and the glass cutter must be operated with one hand. In addition, there is a problem that it is difficult to cut the thick plate glass because it cannot be cut with sufficient force.

In order to solve the above problems, an object of the present invention is to provide a glass edge cutting cutter which can easily and accurately perform narrow width cutting without using a ruler.

[0005]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention is directed to a holder portion provided at a lower end of a tip of a hand grip by projecting an arm portion on a side surface at a tip of the hand grip. Attach a rod that is placed at a right angle to the handgrip so that its position can be adjusted in the longitudinal direction, and attach a glass stopper for moving along the edge of the glass to the lower end of the holder part. The cutter head is attached to the lower surface of the end of the.

[0006]

[Operation] While holding the handgrip to bring the glass contact into contact with the edge of the plate glass, and with the cutter head attached to the end of the rod in contact with the plate glass, force is applied to press the plate glass with the cutter head. By moving the entire glass contact along the edge of the plate glass while adding, it is possible to make a cut parallel to the edge on the plate glass, and at the time of this movement, press down the arm part with the other hand. If added, the cutting power of the cutter head can be improved, and even thick glass can be cut cleanly.

[0007]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in the figure, an arm member 2 is detachably fixed to one side surface at the tip of a handgrip 1 having a rectangular cross section and having a length in the front-rear direction that can be grasped by one hand. A block-shaped holder member 4 is fixed to a shaft 3 protruding downward from the lower end of the tip 1.

The handgrip 1 is attached to the holder member 4.
Is provided with a square hole 5 penetrating in a direction perpendicular to the length direction of the hand grip 1.
It is held in a right-angled arrangement and its position can be freely adjusted in the length direction. On the lower end surface of the holder part 4,
7 pieces per glass are detachably attached with screws.

In the illustrated case, the glass contact 7 is in the form of a plate that is long in the front-rear direction, and is fixedly arranged at a position below the tip of the grip 1 so that the length direction thereof is along the length direction of the hand grip 1, and the lower surface thereof. As shown in FIG. 2, a step portion 8 is formed over the entire length in the length direction for pressing and sliding on the edge of the plate glass A.

For fixing the above glass 7 to the holder portion 4, an inverted L-shaped mounting member 10 is provided along the outer surface of the rising wall 9 provided on the upper surface, and the mounting member 10 and the rising wall 9 are fixed.
This is done by screwing a screw 11 passing through the holder part 4 into the holder part 4.

A screw 12 for fixing the rod 6 to a piece located below the rod 6 is attached to the mounting member 10 and the rod 6 is fixed to the holder portion 4 at an arbitrary position in the longitudinal direction. I can do it.

A cutter head 13 is attached to one end of the rod 6. In the case of the cutter head 13, an example using an oil cutter is shown, and the head 15 is rotatably supported by a cylinder shaft 14 fixed to the lower surface of the end of the rod 6,
While the cutter blade 16 is pivotally fixed to the lower end of the head 15,
An oil set screw 17 is provided on the upper surface side of the rod 6.

A passage 18 for storing oil is provided inside the rod 6 along the length direction, and an inlet of the passage 18 opened at the other end of the rod 6 can be opened and closed by an oil injection screw 19. At the same time, one end of the passage 18 communicates with the oil passage of the cylinder shaft 14 and the head 15 connected to the cylinder shaft 14. When the oil set screw 17 is screwed in, the above communication is cut off, and when loosened, the passage 18 becomes a communication oil. Are supplied to the cutter blade 16.

The cutter head 13 can be attached to and detached from the rod 6 so that the rod 6 can be attached to the holder portion 4 in the left-right direction.

In the case of the drawing, the edge-cutting cutter is shown as being set for a right-handed person. In the front view of FIG. Head 13 is attached, and further 7 per glass
The step portion 8 is located on the right side, but in the case of a left-handed person, the above-mentioned respective parts may be arranged and fixed so that they are left and right opposite to these.

Further, the cutter head 13 is not limited to the oil cutter as shown, and the rod 6 has a distance from the cutter head 17 to the step portion 8, that is, a cutting width as shown in FIG. A graduation 20 for reading with may be additionally provided, and the glass contact 7 may have a structure in which rollers are arranged in a portion in contact with the end face of the plate glass A.

The edge-cutting cutter of the present invention has the above-mentioned structure, and the position from the cutter head 13 to the step portion 8 is set to the width of the small width cutting by adjusting the position along the length direction of the rod 6. , Hold the handgrip 1 with one hand and press the stepped portion 8 per glass placed on the sheet glass A against the edge of the sheet glass A. In this state, the whole edge of the sheet glass A is guided by 7 per sheet of glass. The cutter head 13 pressed against the plate glass A makes a cut parallel to the edge.

At this time, if the arm portion 2 is pushed down by the other hand, the pushing down force is applied to the cutter head 13.
Can be efficiently transmitted to the plate glass, a cut can be surely made on the plate glass A, and even a thick plate glass can be cut cleanly.

If a cut is made in the entire length of the plate glass A, the plate glass A can be cut from the cut portion to make a narrow cut, and the plate glass can be bent after the handgrip 1 as shown in FIG. It suffices to pry the hand grip 1 with the groove of the groove fitting 21 provided at the end fitted in the plate glass.

[0021]

[Effect] As described above, according to the present invention, the narrow cutting of the plate glass can be performed without using a ruler, and the narrow cutting can be easily and accurately performed.

Further, since the arm portion is provided on the side surface of the handgrip, the cutter head can be firmly pressed against the plate glass by pushing down the arm portion with the free hand, and the thick plate Even glass can be cut easily and cleanly.
