Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a glass cutter equipped with a scribing member.

[Conventional technology]

When cutting plate glass using a glass cutter,
Cutting is performed by measuring the dimensions with a scale, marking lines, and moving the head of a glass cutter along a ruler placed to connect the marking lines.

Conventionally, there are the following methods for marking a sheet glass.

(I) Prepare two glass cutters: one for cutting and one for scribing.

() A sharp scribing member is provided protruding from the end of the grip handle for glass cutting, and scribing and cutting are performed with one glass cutter.

() Use a glass cutter to make marking lines.

[The problem that the idea attempts to solve]

By the way, the above-mentioned method (I) requires cutting two pieces of glass, which is not only uneconomical but also troublesome.

In addition, since the tip of the scribing member in () protrudes from the grip handle, it is dangerous to get stuck in the hand when using the glass cutter, and if the glass cutter is stored in a pocket, the pocket etc. may be damaged. There is a problem.

Furthermore, with the above-mentioned method (), the glass cutter is usually structured to apply oil to the cutter, so even if you use the cutter to make the marking lines, the oil will get into the marking lines, making it extremely difficult to see. There is a problem of inaccurate glass cutting.

The purpose of this invention was to solve the above-mentioned conventional problems by making it possible to mark and cut glass with a single glass cutter, to make clear marking lines accurately, and to make it safe and convenient for pockets, etc. The purpose is to provide glass cutting that does not cause damage.

[Means to solve the problem]

In order to solve the above-mentioned problems, this invention has a configuration in which a head having a cutter is attached to one end of the gripping handle, and a scribing member is foldably provided at the other end of the gripping handle. It is.

[Effect]

To add marking lines when cutting glass,
The scribing member is folded along the grip handle and pulled up, the tip of the scribe member is used for scribing work, and the scribe member is folded along the grip handle when cutting glass or when not in use.

[Example] Hereinafter, an example of this invention will be described based on the accompanying drawings.

As shown in the figure, a gripping handle 1 made of synthetic resin or the like has an oil storage chamber 2 inside thereof, and a head 4 is attached to the tip of a core tube 3 which is threadedly connected to one end of the gripping handle 1.

The head 4 is formed in the shape of a rectangular block, and a cutter 5 is pivotally fixed to the forked portion at the tip, and a cylinder shaft 6 is inserted into a vertical hole provided directly above the cutter 5. It is attached to the core tube 3 by inserting the upper end into the core tube 3 and fixing it. The head 4 is fixed to the cylinder shaft 6 with a screw 7 so as to be able to rotate at a certain angle.

The inside of the core tube 3 serves as an oil passage 8 that communicates the oil storage chamber 2 with the inside of the cylinder shaft 6, and an oil supply brush 9 is incorporated in the cylinder shaft 6 to apply and supply the oil flowing out from the oil passage 8 to the cutter 5. It is.

An opening/closing plug 10 screwed onto the other end of the gripping handle 1
The spherical head part acts as a hammer, which seals the upper end opening of the gripping handle 1 in the screwed state, and also seals the upper end opening of the gripping handle 1.
An axial cut portion 12 is provided on the circumferential surface of the valve, and when the stopcock 10 is loosened, the inside of the oil storage chamber 2 is communicated with the atmosphere through this cut portion 12, and the oil in the storage chamber 2 is replaced with air. This allows the oil to flow out into the oil passage 8. Note that in place of the cut portion 12, a hole may be provided that penetrates from the circumferential surface of the screw shaft to the tip.

At the upper end of the core tube 3 facing into the oil storage chamber 2,
An elastic cylinder 13 is fixed in communication with the oil passage 8, and the upper end of the elastic cylinder 13 forms a valve seat 14.

A shaft body 15 is coaxially fixed to the tip of the screw shaft 11 of the opening/closing valve 10, and a cylindrical, sharp-pointed valve body 16 corresponding to the valve seat 14 is attached to the tip of the shaft body 15.

When the opening/closing plug 10 is screwed into the grip handle 1 to seal the upper end opening, the valve body 16 comes into pressure contact with the valve seat 14 as shown by the solid line in FIG. 2, thereby cutting off communication between the oil storage chamber 2 and the oil passage 8. The length of the shaft body 15 is set as follows.

Incidentally, the opening/closing valve 10 may have only the screw shaft 11 without the valve body 16.

Further, the head 4 is not only used for cutting plate glass as shown in the figure, but also a head with a narrower width for stained glass may be used.
A coil spring may be incorporated between the two to facilitate cutting of thick plate glass or stained glass.

A recessed groove 21 along the length direction is provided on the outer surface of the other end of the gripping handle 1, and the base end of the scribing member 22 is pivoted with a pin 23 midway within the recessed groove 21, and the scribing member 22 is The member 22 is rotatable around a pin 23.

In the illustrated case, a recessed part 24 is provided on the outer surface of the grip handle 1 at a position on the inner end side of the recessed groove 21, and the marking member 22 folded and stored in the recessed groove 21 is placed at the tip of the finger in the recessed part 24. It is designed so that it can be pulled up by pinching it.

The scribing member 22 has a hard sharpened portion 2 at the tip.
2a, and when the grip handle 1 is pulled up and tilted toward the end side of the handle 1, the opening/closing stopper 10 is opened as shown in FIG.
It protrudes a little more than the tip of the head.

Note that a leaf spring 2 is attached to the pivoting part of the marking member 22.
5 is incorporated to prevent the marking member 22 from wobbling.

The glass cutter of this invention has the above-mentioned structure, and when the scribing work is not performed, the scribing member 22 is folded and stored in the groove 21, as shown in FIGS. 1 to 3. , it is in a state that it does not protrude to the outside of the grip handle 1.

To mark a line on a plate glass, pull up the marking member 22, make the tip protrude from the end of the grip handle 1 as shown in Fig. 4, grasp the grip handle 1, and use the sharp point 22a to mark. The scribing member 22 is stable in terms of strength because the pivoting side portion of the scribing member 22 is fitted into the groove 21 and held therein.

When cutting glass, hold the grip handle 1 upside down so that the head 4 faces downward, loosen the stopper 10 to supply outside air into the oil storage chamber 2, and use the oil supply brush to remove the oil in the oil storage chamber 2. At step 9, the coating is supplied to the cutter 5 so that the cutter 5 can smoothly cut the glass.

At this time, the valve body 16 is
You can freely set the distance between the valve seat 14 and the cutter 5.
The oil supply amount can be freely adjusted.

[Effects] As described above, according to this invention, the scribing member is foldably provided at the other end of the gripping handle, which has a head with a cutter attached to one end. It allows for efficient scribing and cutting of glass.

In addition, the marking material can be used independently, so
Clear marking lines can be made without the marking lines becoming invisible due to oil, and the marking member can be folded and stored along the grip handle, so there is no chance of damage to pockets etc. when storing. It does not stick to your hands, etc.
Safety can be improved.
