JPS6041074Y2 - Safety cover for plate cutter - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to a safety cover for a plate cutter.

In other words, it is a safety cover that can be easily attached to and removed from disc-shaped cutters such as brush cutters, and it can be attached to cutters of different shapes and sizes without coming off, and the overall design is lightweight and compact. , which can be easily manufactured and suitably implemented.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a perspective view of the entire brush cutter, including an engine 4, a hanging section 5, an operating rod 6, a handle 7, a transmission case 8, and a cover 9.
The brush cutter is equipped with a disc-shaped cutter A having a mounting hole 10 in the center and a blade part a on the periphery on the tip side of the brush cutter. Cutters of various shapes, such as a rectangular upper blade, can also be attached.

The main body of the safety cover B is formed into a belt shape that is longer than the circumferential length of the various cutters.The main body B is formed into a U-shape in cross section, and the inside of the main body B has a width that allows the blade part a of the cutter A to be inserted. A fitting groove 1 having a depth is formed over the entire length, and a large number of V-shaped notches 2, 2 are provided at intervals in the longitudinal direction on both sides of the main body B so that the open side of the main body B can be bent. In order to maintain the shape, on the back side of the U-shaped fitting groove 1 of the main body B, a protruding piece 3 having a width and depth that can be fitted into the fitting groove 1 is integrally formed extending in the longitudinal direction, and the entire body is molded from a synthetic resin material. .

Therefore, as shown in FIG.
When the fitting groove 1 of the safety cover is fitted into the safety cover and the safety cover is wrapped around the cutter A, the safety cover can be installed along the circumference of the cutter A while being curved by the notch 2.
Once it has been wrapped around the cutter A, align the other end of the safety cover above one end of the safety cover as shown in Figure 7, and fit the fitting groove 1 of the other end into the protrusion 3 of the one end. Then, a part of the material will polymerize and a safety cover can be attached.

Conversely, it can be removed by pulling out the safety cover.

In addition, if cutter A has a small diameter, a safety cover can be attached to cutter A by overlapping it twice, and
It can also be attached to this type of star cutter or upper blade.

In this way, the present invention has a transversely U-shaped main body with a groove formed over its entire length into which the cutter blade can be inserted, and a belt-like shape that is longer than the circumference of the cutter, allowing the main body to be bent. A large number of notches are formed at intervals in the longitudinal direction, and a projecting piece that fits and locks into the fitting groove is integrally formed on the back side of the main body, and the whole body is made of a synthetic resin material. Depending on the part, the safety cover can be curved or bent and installed while aligning with the cutter.
Insert the blade of the cutter into the insertion groove and safely cover it with the safety cover, wrap it once, and then insert the safety cover on the other end from the end of the winding over the outer protrusion on the one end where you started winding. It can be installed by fitting into the groove and locking it, and it can be installed reliably to prevent it from coming off even with cutters of different shapes and sizes.The overall feature is that it is lightweight and compact, making it easy to manufacture and suitable for implementation. has.
