Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to manual glass cutting for cutting plate glass.

[Prior art and problems]

Conventional manual glass cutters used to cut sheet glass have a gripping rod shaped like a substantially straight square or circular shaft, and a cutter blade is attached to a head attached to the tip of the gripping rod that can rotate freely. It was a pen holder type with a pivot structure.

By the way, in order to cut a plate glass, it is necessary to apply sufficient force to the cutter blade via the gripping rod in order to cause cutting scratches on the plate glass with the cutter blade.

However, the pen holder type gripping rod, which is shaped like a square or circular shaft, must be held with only the fingertips, which makes it unstable to hold, making the hands tiring if the work is repeated many times, and requiring too much hand strength. There is a problem in that the cutter blade cannot sufficiently act as a pressing force on the plate glass.

[Purpose of the invention] This invention was made to solve the above problems, and was designed to create a glass cutter that can be held stably with the fingertips and that can sufficiently transmit the force of the hand to the cutter blade. The purpose is to provide.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention attaches a head with a cutter blade pivoted to the tip of a gripping tube whose interior is an oil storage chamber, and the cutter blade drains the oil in the storage chamber inside the head. A lubricating brush for applying oil to the oil is incorporated, and a non-slip member for receiving the palm of the hand is provided protruding from the grip tube so as to be freely rotatable.

[Effect]

Hold the tip of the gripping tube between your thumb and forefinger, place your middle finger on the side of the head, press the area between your thumb and forefinger on the non-slip surface, and press the cutter blade against the plate glass to remove the head. By moving the cutter along the ruler, you can make cutting scratches on the glass plate, and since your palm rests on the anti-slip surface, your hand will not slip against the grip tube, and you can apply sufficient hand force to the cutter blade. I can do it.

〔Example〕

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

As shown in the figure, the grip cylinder 2 whose vertical hole passing through along the axis serves as the oil storage chamber 1 is formed into a cylindrical shape with a tapered tip, and the cylinder shaft 3 is an extension of the storage chamber 1 at the tip. It is fixed in a protruding shape so as to form a shape, and a small diameter part 4 is formed from the middle part to the upper end.

The head 5 attached to the tip of the gripping tube 2 is formed in the shape of a rectangular block, and a cutter blade 6 is rotatably pivoted to the forked portion of the tip.
A vertical hole 7 provided so as to be located directly above the cylindrical shaft 3
It is fitted externally.

The head 5 is attached to the tip of the gripping cylinder 2 via the cylinder shaft 3, and the tip of the screw 9 screwed into the screw hole 8 of the head 5 faces the flat recess 10 provided on the outer peripheral surface of the cylinder shaft 3. The head 5 can be prevented from coming off and can be rotated at a certain angle with respect to the cylinder shaft 3.

The tip of the oil supply brush 11 incorporated inside the cylinder shaft 3 slides on the upper peripheral edge of the cutter blade 6, and the oil filled in the storage chamber 1 can be applied to the cutter blade 6 via the oil supply brush 11. It's becoming like that.

The upper end opening of the storage chamber 1 serves as a fuel filler port 12,
The screwed cap 13 can be opened and closed freely, and when the cap 13 is loosened, air flows into the storage chamber 1, allowing smooth application of oil to the cutter blade 6.

A non-slip member 14 attached to the small diameter portion 4 of the gripping tube 2
is formed by protruding a projecting piece 16 on the outer periphery of a cylindrical part 15 that fits onto the small diameter part 4, and a retaining ring 1 is attached to the small diameter part 4.
7 so that it cannot be removed, and is rotatable around the small diameter portion 4.

This anti-slip 14 has an arc-shaped surface 18 at the transition point from the cylindrical portion 15 to the protrusion 16 so that the thumb and index finger of the palm can be placed along the protrusion 16 stably.
is formed.

In the example shown in FIG.
6 is provided at a position offset to one end with respect to the longitudinal direction of the cylindrical part 15, and this non-slip 1
4 can be freely attached and detached from the small diameter portion 4 of the grip tube 2 by removing the cap 13, and by attaching it upside down, the protruding position of the protruding piece 16 relative to the grip tube 2 can be changed.

That is, the size of the hand that holds the glass cutter varies depending on the person, and if the position of the protrusion 16 is constant,
It may be difficult to place your fingertips along the side of the head 5.
For this reason, if the anti-slip 14 is installed as shown by the solid line and the dashed-dotted line in FIG. 8, and the distance from the protrusion 16 to the head 5 is adjusted to match the hand, the holding will be stabilized.

In addition, as shown in the figure, if a notch 19 is provided on the side surface of the head 5 to fit into the edge of the plate glass, and the notch 19 is inserted into the plate glass with a cut line in it to fold the plate glass, the cutting work of the plate glass can be done smoothly. I can do it.

The glass cutter of this invention has the above-mentioned structure, and the tip of the grip tube 2 is held between the thumb and forefinger, the protrusion 16 of the anti-slip 14 is placed between the thumb and forefinger of the palm, and the tip of the middle finger is placed between the thumb and forefinger. The head 5 is placed on a ruler in a state along the side surface of the head 5, and the cutter blade 6 is moved along the ruler while pressing the cutter blade 6 against the glass plate to make cutting scratches on the glass plate.

At this time, the anti-slip 14 is 360° with respect to the grip tube 2.
Since it is rotatable, the head 5 can be stably aligned with the ruler, and the force of the hand can be applied to the cutter blade 6 via the non-slip 14, allowing efficient and stable cutting. Ru.

〔effect〕

As described above, according to this invention, the force of the hand can be sufficiently transmitted to the cutter blade due to the anti-slip feature, making it possible to reliably make a cutting line on the plate glass, and increasing the gripping force with the fingertips. There is no need for this, and long cutting work can be done without any trouble.

Furthermore, since the non-slip member is rotatable relative to the grip tube, the head can be stably aligned with the ruler.
