Description

[Detailed Description of the Invention] The present invention relates to scissors for cutting the slats of blinds, and is particularly intended to be used when reducing the width of blinds already assembled in a factory.

Conventionally, when blinds were purchased with the wrong dimensions, it was easy to shorten the length in the height direction, but to shorten the width in the horizontal direction, it was necessary to cut the blind box, slats 1, and the bottom plate, especially when cutting the slats. Because there were a large number of slats to cut and there were no affordable scissors to cut the slats, it was extremely difficult to reduce the width of the blinds.

Further, although commercially available scissors can be used to cut the slats, it is very troublesome and troublesome to round the cut portion of the slats after cutting them.

Furthermore, even if scissors for cutting slats were available, they were complicated to operate and expensive, making it uneconomical to use them specifically for blinds in general households.

The present invention aims to improve the above-mentioned drawbacks and provide scissors specifically for blind slats that are safe, inexpensive, and easy to use even in general households.

The present invention will be explained below with reference to the drawings.

FIG. 1 shows an outline of one embodiment of the scissors of the present invention, which is used as a cutting blade for slats with a slat width of W1. It is designed so that two types of W2 slats can be cut with one pair of scissors.

In the figure, 1 is the receiving blade, 2 is the movable blade, 3 is the pivot pin for pivotally connecting the receiving blade 1 and the movable blade 2 in an X shape, 4 is the arm of the receiving blade 1, and 5 is the movable blade 2 The arm part of the figure is shown.

The arm portion 4 of the receiving blade 1 is provided with stepped portions 6 and 7 corresponding to the slat widths W1 and W2, and the edges of the stepped portions 6 and 7 are provided with cutting edges corresponding to the edge shape of the slat to be cut. Edge 6'
and 7' are formed.

In addition, the arm portion 5 of the movable blade 2 has a stepped portion 6 of the receiving blade 1 described in ``1''.
A side edge with recesses 9 and 10 is provided at positions corresponding to
' is formed.

In the one shown in FIG.
Edges 5a and 7a are formed in a concave shape from the upper edge and are provided at both ends of the step portions 6 and 7 to position the slats during cutting.
is formed.

FIG. 2 is a side view showing a slat 21 being cut by the scissors of the present invention, and FIG. 3 is a slat cut by the scissors of the present invention.

Next, an embodiment in which slats are cut using the scissors of the present invention will be described.

Step 6 or 7 depending on the width of the slat to be cut.
The slat is passed through the slat, and both edges of the slat are placed against the edge 6a or 7a of the stepped portion 6 or 7 to hold the slat so that it does not wobble.

Therefore, the slats, on which a score line has been drawn in advance on the long strip to be cut, are positioned at the cutting edges 6' and 7' of the receiving blade along the score line, and the arm 5 of the movable blade 2 is rotated. By doing this, the slats can be cut into the desired length.

Since the cutting edges 6', 7' are formed with blades having the shape to be cut, the slat 21 can be easily and cleanly cut into the desired shape, as shown in FIG.

Further, the arm portion 4 of the receiving blade 1 of the scissors is provided with step portions 5 and 6 for positioning the slats 21 and 22, and the movable blade 2
The side edge 8 of the arm portion 5 has cut edges 6' of the notch steps 6, 7,
Cutting portions 9' and 10' are formed at opposite positions to 7', and these cutting edges are integrally formed on the arms of the scissors, so these scissors can be produced in large quantities at low cost and are inexpensive. , and the edges of the slats can be cut correctly.

FIG. 4 shows another embodiment of the slat cutting scissors according to the present invention.

In this embodiment, parts similar to those shown in FIG. 1 are designated by the same numerals.

This embodiment is generally similar to that shown in FIG. 1, but the steps 6 and 7 forming the cutting edges 6' and 7' are recessed from the upper edge of the arm 4 as shown in FIG. The upper edge of the arm portion 4 is not formed in any particular shape, but has a shape in which the upper edge of the arm portion 4 is rounded and bent inward.

Therefore, in the embodiment shown in FIG. 4, the locations corresponding to the edges 5a, 7a for positioning the slats during cutting are not formed.

However, in FIG. 4, a positioning member 11 for positioning the slats is attached to the side wall of the arm 4, and its positioning protrusion 12 projects above the steps 6 and 7.

The scissors shown in FIG. 4 are used in exactly the same way as those shown in FIG. Similarly to the above, the slat is cut by placing the part to be cut against the cutting edges 6', 7' of the receiving blade and rotating the arm 5 of the movable blade.

This invention can be easily used in ordinary households like a double blade, and can also be used as a blade for cutting slats.
It can cut two types of slats with different widths, 25 mm and 35 mm, which are popular for blinds.
To provide convenient scissors that can be used as a single scissor for cutting mm type slats.
