Abstract

(57) [Summary] [Purpose] Circular and irregular cutouts of flat glass can be performed.
In addition, we aim to make the whole compact. [Structure] The rods 1 and 2 are connected by a joint structure 3 capable of selecting bending and stretching of both rods 1 and 2, and a suction cup 4 is attached to the tip of one rod 1 and a cutter is attached to the tip of the other rod 2. Attach the head 5. If the suction cup 4 is sucked and fixed on the plate glass and both rods 1, 2 are fixed by the joint structure 3, a circular cutout can be performed by rotating the cutter head 5 centering on the suction cup 4. If the joint structure 3 is loosened so that the rods 1 and 2 can be bent and stretched freely, the cutter head 5 can be freely moved in a plane and an irregular cutout can be performed. Further, when not in use, the rods 1 and 2 are folded to make the whole compact.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a plate glass variant and a circle cutter for cutting a plate glass into an arbitrary shape or a circle.

[0002]

[Prior Art]

 Conventionally, a circle cutter for cutting a plate glass into a circle has a holder attached to one rod end with a suction cup for a fulcrum, which is attached to the rod so that the position can be adjusted in the length direction. Attach the cutter head to the, and set the dimension from the suction cup to the cutter head with the suction cup fixed on the plate glass.In this state, rotate the rod around the suction cup and make a circular cut in the plate glass with the cutter head. It was supposed to be cut out.

[0003]

[Problems to be solved by the device]

 However, the conventional circle cutter has a problem in that it is very inconvenient to use it in the field because the rod is long to cut out a large circle.

In addition, the conventional circle cutter can cut out only a circular shape, and has a narrow application.

In order to solve the above-mentioned problems, the present invention provides a plate glass variant and a circle cutter that are compact but can perform a large circular cutout and can also perform a desired variant cutting. The task is to do.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention connects a plurality of rods so that they can be stretched and folded, and a suction cup is provided at one end of this rod group and the other rod is connected. The cutter head is attached to the end, and the connecting part of each rod has a joint structure in which fixing and rotation of the rods can be selected.

[0007]

[Action]

 With the suction cup fixed on the plate glass, open the rod at a predetermined angle, and operate the joint structure to fix the rods to each other.By rotating the cutter head around the suction cup, a circular plate is formed on the plate glass. You can make a cut.

Further, when the joint structure is loosened, the rod can be flexed and extended freely, the cutter head can be moved to an arbitrary shape, and cutting other than a circular shape can be performed.

[0009]

【Example】

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

As shown in FIG. 1, the two rods 1 and 2 are connected by a joint structure 3 so as to be able to flex and extend, and a suction cup 4 is attached to the tip of the one rod 1 and the tip of the other rod 2. A cutter head 5 and an oil tank 6 are attached to the.

As shown in FIG. 2, the joint structure 3 includes rubber or the like between a disk 7 fixed to the upper surface at the end of one rod 1 and a disk 8 fixed to the lower surface at the end of the other rod 2. With the elastic member 9 in between, the bolt 10 penetrating the center of the upper disk 7 and the elastic member 9 is screwed into the central screw hole 11 of the lower disk 8, and the bolt 10 is turned by the lever 12 of the head. By moving, the upper and lower discs 7 and 8 sandwiching the elastic member 9 are tightened and loosened, and both rods 1 and 2 are fixed at the time of tightening, and both rods centering around the bolt 10 are loosened. 2 can be freely rotated. Therefore, by tightening and loosening the bolt 10, both rods 1 and 2 can flex and extend freely, and a fixed state at a desired angle can be obtained.

On the other hand, as shown in FIG. 3 (A), the suction cup 4 attached to the tip of the rod 1 is provided with a cylindrical shaft 15 on the upper surface of a metal disk 14 having a concave tapered surface 13 on the lower surface. 15 is rotatably supported by the tip of the rod 1, the metal disc 14 is positioned under the tip of the rod 1, and the circular rubber plate 16 and the cylindrical shaft 15 are arranged so as to overlap with the lower surface of the metal disc 14. The cam lever 17 arranged at the upper end of the above is connected by a connecting rod 18.

In the state where the cam lever 17 is upright, as shown in FIG. 3A, since the pulling force does not act on the circular rubber plate 16, no suction force is generated on the suction cup 4, but as shown in FIG. When the circular rubber plate 16 is laid down, the center of the circular rubber plate 16 is pulled up and the lower suction surface is recessed, and a suction force is generated on the plate glass A, so that the suction cup 4 fixed on the plate glass A is slid. 1 can freely rotate in a plane around the axis of the suction cup 4.

On the other hand, as shown in FIG. 4, the cutter head 5 attached to the tip of the rod 2 has a head attached to the lower portion of a cylindrical shaft 19 attached to the lower portion of the front end of the rod 2 so as to be vertically movable and rotatable. 20 is rotatably provided, and a cutter 21 is pivotally fixed to the lower end of the head 20.

The oil tank 6 is attached to the upper end of the cylindrical shaft 19 projecting above the rod 2, and serves as a grip for pressing and moving the cutter head 5, and the upper end of the oil storage passage 22 provided inside the oil tank 6. It can be opened and closed by an oil injection screw 23, and the lower end of the oil storage passage 22 is connected to the passage 24 provided in the cylinder shaft 19 and the head 20 to supply oil to the cutter 21. The cutter head 5 and the oil tank 6 are pushed up by a spring 25 to a raised position.

Although not shown, a scale indicating the distance from the center of the suction cup 4 to the cutter head 5 is attached to the disc 7 of the one-sided rod 1 in the joint structure 3 depending on the angle between the two rods 1 and 2. On the other hand, the circular cutout diameter may be set by reading the scale on the rod 2 for reading.

The cutter of the present invention is constructed as described above, and in a state where it is placed on the plate glass A, the cam lever 17 is first tilted to suck and fix the suction cup 4 to the plate glass A, and then a circular cutout is performed. In this case, tighten the bolts 10 of the joint structure 3 with the angles of both rods 1 and 2 set so that the distance from the center of the suction cup 4 to the cutter head 5 becomes the desired radius. Fix 2 and 2.

In this state, when the oil tank 6 is gripped and the cutter 21 is pressed against the plate glass A and is rotated about the center of the suction cup 4, the cutter 21 is centered on the plate glass A. A circular cut will be made, and a circular cut can be made to the plate glass.

Further, when the plate glass is cut out into a shape other than a circular shape, the bolt 10 in the joint structure 3 may be loosened, and both rods 1 and 2 can be flexed / extended, so that the cutter head 5 is flat. It can be moved freely, and the desired shape can be cut out.

When cutting out large-sized circles or irregular shapes, as shown in FIG. 5, a rod 1a may be provided between the rods 1 and 2 to increase the number of connecting rods. The joint structure 3 allows bending and extension and fixation.

[0021]

【effect】

 As described above, according to the present invention, a plurality of rods are connected so that they can be bent and extended and fixed freely, a suction cup is attached to one end of the rod rod, and a cutter head is attached to the other end. Since it is attached, you can freely cut out circular and irregular shapes of plate glass, and when not in use, the whole rod can be folded down by folding the rod, making it convenient to carry.

Further, by combining a plurality of rods, even during the cutting work, there is little occurrence of an obtrusive protruding portion, and the cutting work can be performed smoothly.
