Description

This invention forms the insertion path of the shredded paper insertion part by a plurality of curved surfaces, by continuously inconsistently the bending direction of each surface, fingers, some of the clothing, metal plate, etc., is cut not Or a technique for preventing insertion of a foreign substance that impedes the cutting function.

Currently, when cutting paper with a shredder, there are painful accidents such as a part of clothing accidentally getting caught, or a child inserting a finger and a finger that has been detected and cut by both hands. is happening. In addition, there are not a few accidents in which the cutter blade is damaged by the insertion of foreign matter such as a metal plate or hard plastic. In particular, accidents that cut fingers are a social problem.

  These are all because the insertion path of the shredder paper insertion part has been designed only to be suitable for paper insertion, and many shredders constitute a straight path suitable for paper insertion, This is due to the lack of ergonomic considerations for accident prevention.

Problems to be solved by the invention

The present invention bends the insertion path of the above-mentioned paper insertion portion into a shape that prevents insertion of a finger or the like, thereby preventing the insertion material from going straight at the time of insertion, thereby preventing erroneous insertion action or insertion insertion of an inappropriate insertion material. It is to prevent.

Means for solving the problem

In order to solve the above-described problem, the shredder insertion path according to the present invention extends at least the paper insertion portion of the paper or film toward cutting to a surface extending around the paper insertion portion, and the periphery of the paper insertion portion. If the direction of the surface extending in the plane direction is a plane direction, the paper insertion section path extends in the vertical direction with respect to the plane direction to form the paper insertion section path and the paper insertion section path. The cross-sectional shape showing the shape in the elevation direction of the paper guide wall formed in the whole or a part of the paper insertion portion path, the direction in which each of the plurality of curves swells in one paper guide wall is contradictory. As a result , the paper guide wall of the other side is also formed of a substantially S-shaped curve, and the distance between the two curves is a deliverable width of paper or the like toward cutting. Keep the cross-sectional shape A curved path formed by extending along the extending direction of the insertion path and continuing the width formed by the paper guide wall of the insertion path to an extent that does not impair the prevention effect by bending, The insertion of the first unsuitable material such as a fingertip, which is to be inserted while bending the joint, and the second unsuitable material such as a metal plate or a hard plate is prevented from being inserted, and this prevents the careless cutting.

The invention's effect

Since the conventional shredder path is directed straight to the cutting cutter as shown in FIG. 1, it has an efficient structure for cutting paper and the like, but there is a risk that a fingertip or the like is erroneously inserted, On the other hand, if the insertion slot is narrowed in order to prevent erroneous insertion, there is a disadvantage that the number of inserted sheets is reduced and the cutting efficiency is lowered.
The shredder path of the present invention provides these disadvantages as a structure that can prevent danger very effectively, while having a simple and low-cost structure.
In particular, the finger, which is the first unsuitable material for cutting, has a current situation in which the prevention of danger depends only on the attention of the inserting person in spite of the role of inserting the cutting material into the insertion slot in most cases.
In order to solve these problems, the present invention has a feature that a finger bends in one direction by a joint and hardly bends in the opposite direction. On the other hand, papers bend flexibly, for example, in an S-shape. As described above, when a finger is inserted into the generally S-shaped paper insertion path, even if the fingertip enters the first curved path, the opposite curved path forces the bending of the finger in the opposite direction. In this direction, fingers that do not bend the joint are blocked from insertion, and if the finger is inserted from the opposite direction, the insertion is similarly blocked because the joint is blocked by the first curved path and the joint is not bent. The

The shredder insertion path is generally formed in the S-shape in order to prevent accidents in which the unsuitable material for cutting, in particular, a finger or the like is accidentally inserted and damaged, and the width of the insertion path is such that the finger cannot be delivered to the cutting cutter. Alternatively, the insertion path can be prevented from being inserted by adopting a structure having a long dimension of the insertion path.
Further, as shown in FIG. 4, in the shredder insertion path, the paper guide wall is formed in the opposite direction even if an automatic paper feed roller is provided in the middle and the paper to be cut is forcibly fed. ability to prevent the insertion of the cut unsuitable product with a curved surface does not change, by arranging the order automated paper feed roller, the performance is expected to be delivered in the same level as direct-type insertion path illustrating the paper, or the like in FIG. 1 I can do it.

2 and 3 are views showing the configuration of the first embodiment of the shredder insertion path according to the present invention. In the figure, the paper insertion portion path 21 extends in the elevation direction, forms a path width that does not allow a finger or the like to easily enter , and further has a shape that prevents the passage of the first unsuitable cutting material such as a finger. It is made. This shape is formed and restricted by the opposing paper guide walls 21a and 21b. Each of the paper guide walls 21a and 21b has a substantially S-shaped curved surface in which a plurality of curves having opposite directions of expansion are connected to each other, and the opposing paper guide walls form curved surfaces so as to maintain a constant interval. These intervals and the curved surface configuration prevent the finger 22 from reaching the cutting cutter 13, and the other finger 23 to be inserted from the opposite direction is similarly blocked at another portion of the curved surface.
Further, as shown in FIG. 3, the second unsuitable cutting materials 24 and 25 such as a metal plate and a hard plate are cut by the paper guide walls 21a and 21b regardless of whether they are inserted from an upright direction or from an oblique direction. It is not delivered to the cutter 13.
Further, when generally difficult delivery of paper or the like in order is formed in an S shape is made, as shown in FIG. 4, distribution automatic paper feed roller 21c which rotates in the paper feeding direction A on one of the paper guide walls 21a and set, disposed other automated paper feed roller 21d to rotate in the paper feeding direction B to the other paper guide wall 21b, by activating this or the like, can be smoothly delivery of the paper. Note that these automatic paper feed rollers may be arranged only on one of the paper guide walls 21a or 21b. Also, these automatic paper feed rollers achieve the desired performance by increasing the number according to the design conditions.
FIG. 5 is a view in which a paper guide wall, an automatic paper feed roller, and a cutting cutter are mounted. Reference numeral 2 denotes a part of a casing that includes these.

FIG. 1 shows a conventional shredder insertion path. A third paper insertion section path 20 is formed in a straight line by a third paper guide wall 11a and another third paper guide wall 11b which face the cutting cutter 13 and face it. because it is formed, we can not preclude the insertion of the insertion unsuitable product.
