  In recent years, shredders have been used not only in offices of government offices and companies, but also in general households and residential offices. In such a general home or a residential / shared office, a shredder may be provided in a place where an infant can reach.

  Recently, under such circumstances, infants inserted their fingers into the shredder's shredder insertion port, and as a result, painful accidents in which the fingers of the hand were injured by the shredding cutter occurred frequently. Yes. See FIG.

  In view of such a situation, the present invention has been made in order to prevent the risk of injury to fingers of a hand by a shredder shredding cutter.

  In order to solve the above problems, the present invention provides the following shredder safety device and a shredder including the safety device.

(1) The apparatus main body is provided with a guide passage for a shredded object that penetrates the apparatus main body up and down, and even when a person inserts a finger of a hand into the guide passage from the entrance of the guide passage, A shredder safety device characterized in that it does not reach the shredding cutter in the shredder (claim 1).

(2) The apparatus main body has a height that prevents a finger from reaching a shredding cutter in a shredder even when a person inserts a finger of a hand from the entrance of the guide passage into the guide passage. 2).

(3) The guide passage is gradually narrowed downward (Claim 3).

(4) A shredder, wherein the shredder safety device is attached so that the guide passage communicates with a shredder insertion port of the shredder (claim 4).

[Invention of Claim 1]
When the safety device for a shredder according to claim 1 is attached to the shredder so that the guide passage communicates with the shredder insertion port of the shredder, the safety device allows the person's finger to move from the entrance of the guide passage to the shredder. Even when the finger is inserted into the guide passage, the finger is prevented from reaching the shredding cutter in the shredder. There is no risk of touching the cutter. Therefore, the risk of injury to the fingers of the hand by the shredding cutter in the shredder is eliminated.

  The shredder safety device has a simple structure and can be provided at a low cost, and can be retrofitted to an existing shredder. Therefore, the safety of the existing shredder can be secured at a low cost by retrofitting this shredder safety device.

  Further, by attaching the shredder safety device to the shredder at the manufacturing stage, it is possible to ensure the safety of the shredder without changing the design of the shredder which requires a large cost.

[Invention of claim 2]
In order to prevent the finger from reaching the shredding cutter in the shredder even when a person inserts the finger of the hand into the guide path from the entrance of the guide path, the device body is provided with The finger has a height that does not reach the shredding cutter in the shredder even when inserted into the guide passage from the entrance of the guide passage. Therefore, even when a person inserts a finger of the hand into the guide passage, there is no possibility that the finger of the hand contacts the shredding cutter in the shredder. Therefore, the risk of injury to the fingers of the hand by the shredding cutter in the shredder is eliminated. In other words, this shredder safety device secures safety by increasing the distance from the entrance of the guide passage to the shredding cutter in the shredder.

[Invention of claim 3]
Since the guide passage gradually narrows downward, fingers of the hand are prevented from passing through the guide passage and reaching the shredder. Therefore, even when a person inserts a finger of the hand into the guide passage, there is no possibility that the finger of the hand contacts the shredding cutter in the shredder. Therefore, the risk of injury to the fingers of the hand by the shredding cutter in the shredder is eliminated.

  Since the guide passage is gradually narrowed downward, the guide passage may be provided with a sufficient entrance width that facilitates insertion of an object to be shredded.

[Invention of claim 4]
A shredder equipped with a shredder safety device. As described above, even when a person inserts a finger of a hand into the guide passage, there is no possibility that the finger of the hand will contact the shredding cutter in the shredder. Therefore, the risk of injury to the fingers of the hand by the shredding cutter in the shredder is eliminated.

  The reference numeral 1 indicates a shredder safety device, and the reference numeral 3 indicates a shredder.

  In the shredder safety device 1, a device body 5 is provided with a guide passage 9 for an object 7 that penetrates the device body 5 up and down, and a person's finger 11 is guided from the inlet 9 a of the guide passage 9 to the guide body 9. Even when inserted in the passage 9, the finger 11 does not reach the shredding cutter 13 in the shredder 3.

  The apparatus main body 5 is a box-shaped body as an example, but the apparatus main body 5 does not ask what the shape is.

  In order to prevent the finger 11 from reaching the shredding cutter 13 in the shredder 3 even when a person inserts the finger 11 of the hand into the guide passage 9 from the entrance 9a of the guide passage 9, as an example The apparatus body 5 has a height a at which the finger 11 does not reach the shredding cutter 13 in the shredder 3 even when a person inserts the finger 11 of the hand into the guide passage 9 from the entrance 9a of the guide passage 9. It shall have.

  The height a of the apparatus main body 5 is about 50 mm as an example.

  By attaching the apparatus main body 5 having a height a to the shredder 3, the distance b from the inlet 9a of the guide passage 9 to the shredding cutter 13 in the shredder 3 is increased.

  In order to prevent the finger 11 from reaching the shredding cutter 13 in the shredder 3 even when a person inserts the finger 11 into the guide passage 9 from the entrance 9a of the guide passage 9, 11 may be prevented from passing through the guide passage 9 and reaching the shredder 3. That is, the guide passage 9 may be formed so as to be gradually narrowed downward.

  The width of the inlet 9a at the upper end of the guide passage 9 is about 10 mm as an example, and the width of the outlet 9b at the lower end of the guide passage 9 is about 5 to 6 mm as an example.

The shredder safety device 1 is attached to the shredder 3 so that the guide passage 9 communicates with the shredder insertion port 15 of the shredder 3.

The shredder safety device 1 is preferably formed entirely transparent so that the flow of the shredded object 7 can be visually recognized from the outside.

It is sectional drawing which shows the state which attached the safety device for shredders by this invention to the shredder. It is a perspective view which shows the safety device for shredders same as the above. It is sectional drawing which shows the shredder which is not provided with the safety device for shredders.
