Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shredder in which a scrap box for storing shredded scraps is formed under a shredder portion in a pull-out type, and more specifically, the scrap box is formed of a flexible material such as plastic. The present invention relates to a safety mechanism for avoiding danger in the case of being present.

[0002]

2. Description of the Related Art Conventionally, there has been a shredder on a drawer type storage cabinet having a shredder portion provided with a paper inlet and a rotary blade. In such a shredder, for example, when the storage cabinet is composed of a plurality of drawers, the uppermost stage thereof, that is, the drawer immediately below the shredded portion functions as a waste box for shredded waste, and the other drawers are the ordinary drawers. Can be used as a storage box. In addition, by putting this shredder on the sleeve of an existing desk, you can immediately shred unnecessary documents while doing desk work, and when not using the shredder, you can put documents on the shred portion and function as a desk And convenient. Further, the storage cabinet is assembled by a frame and a drawer that can be freely put in and taken out from the frame, and its material is generally formed of synthetic resin such as plastic for the purpose of lightweight and mass production.

[0003]

By the way, since the shredder has a structure in which the paper is shredded by the rotary blade, the safety to the human body must be sufficiently ensured. In other words, it is dangerous for your fingers to touch the rotary blade directly,
Careless entry of fingers into the shreds, whether operating or stopped, must be avoided. But,
In the shredder of the above-mentioned form, the entire storage cabinet is formed of a flexible material such as synthetic resin, and therefore, as shown in FIG.
As shown in FIG. 5, when a force is applied to the waste box (drawer) 10 from the side surface, the side wall 11 is deformed inward, and a gap is formed between the side wall 11 and the shredded portion 20. There is a risk of fingers getting in. This is more likely to occur as the waste box becomes longer in the pull-out direction and the bottom becomes deeper. Therefore, it is necessary to solve these problems in order to avoid danger.

An object of the present invention is to solve the above problems and provide a safe shredder.

[0005]

In order to achieve the above object, the present invention has developed a shredder safety mechanism in which a pull-out type waste box is installed below the shredder. In other words, this safety mechanism pivotally locks the safety guide, which is provided with a stopper at a position corresponding to at least the upper edge of the side wall of the waste box to restrict the inward bending of the side wall, in the pull-out direction of the waste box. It is composed by means. According to this mechanism, when a force is applied to the waste box from the side surface, the stopper in the safety guide comes into contact with the bent side wall, and the side wall is further deformed inward (the side for storing shredded waste). Since it is regulated, there is no gap between the shredded portion and the waste box where fingers can enter. Further, since the safety guide is rotatable in the direction of pulling out the waste box, the waste box can be freely taken in and out without any trouble. In the present invention, the requirement that the stopper "corresponds to at least the upper edge" is that the purpose can be achieved only by contacting the upper edge and restricting the inward deformation of this portion. is there. However, the invention is not limited to this, and the side wall deformation prevention effect is greater as the stopper length is adjusted to increase the contact width with the side wall.

According to the first aspect of the present invention, the safety guides are separately provided corresponding to both side walls of the waste box, but the safety guides may be integrally formed. Therefore, in a second aspect of the present invention, in the first aspect of the invention, a means is used in which the stoppers are connected by a connecting member to form a crank-type safety guide. According to this means, the same deformation prevention effect as that of the first aspect can be obtained, and in addition, the connecting member acts to flatten the shredded scraps which are piled up by inserting and removing the scrap box.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a perspective view of a shredder adopting the configuration of the present invention, in which 1 is a shredded portion,
The inside is provided with a rotary blade (not shown), while the outside is provided with a paper inlet, a necessary power switch, and the like. The basic configuration of these shredded portions is not limited to the illustrated form, and all shredded portions in a known shredder are applied. 2 is a lower cover of the shredder 2, 3 is a waste box having a box shape corresponding to the lower structure of the lower cover 2,
Reference numeral 4 is a storage box having a configuration substantially similar to that of the waste box 3. Further, 5 is a frame for housing the waste box 3 and the storage box 4 in a pull-out manner, and the basic configuration thereof is a shape in which four columns 6 ... Then, the four corners of the lower cover 2 are stably placed on the top end of the frame 5. Therefore, when the waste box 3 and the storage box 4 are made of a transparent material,
There is an advantage that it is possible to check at a glance how much shredded waste is stored in the waste box 3 and the documents stored in the storage box 4. Further, the waste box 3 and the storage box 4 are often made of synthetic resin such as plastic for the purpose of lightweight and mass production, but in the present invention, the waste box 3 is made of such a flexible material. Configure a safety mechanism only for the purpose.

The details of the above-mentioned shredder safety mechanism will be described below. FIG. 2 is a perspective view showing the relationship between the safety guide 7 and the waste box 3, in which the shredder 2, the storage box 4, and the frame 5 are omitted for convenience of explanation. In this embodiment, the upper edges 3b, 3 of the side walls 3a, 3a of the waste box 3 are
Corresponding to b, the stoppers 7a, 7a located inside thereof
A safety mechanism is configured by axially fixing the safety guide 7 having the above to the guide bracket 2a formed on the lower cover 2. Further, the stoppers 7a and 7a are linked by a connecting member 8 to form a crank shape with a recessed middle as a whole. With this configuration, as shown in FIG. 3, even if an external force P is applied to the waste box 3 from the side surface, the stopper 7a contacts the upper edge portion 3b and the side wall 3a is further deformed inward. You can regulate things. Therefore, there is no space between the waste box 3 and the lower cover 2 for the fingers to enter, and even if the waste box 3 is formed of a material that is easily bent, the fingers do not enter the shredded portion 1 and it is safe. is there. Here, when a gap is provided between the stopper 7a and the side wall 3a for smoothly inserting and removing the waste box 3,
It is conceivable that the safety guide 7 moves to the left and right along with the bending of the side wall 3a by that amount, but in this embodiment, the length L of the connecting member 8 is adjusted so as to correspond to the inner width W of the waste box 3. Since the gap is minimized, there is no inconvenience due to movement of the safety guide 7. In addition to this, as a shaft stopping means for restricting the movement of the safety guide 7, there is a cotter pin in the shaft portion 7b of the safety guide 7, etc. However, the adoption of other known means has no effect on the configuration of the present invention. Not something to give.

On the other hand, since the safety guide 7 is rotatably pivoted in the direction in which the waste box 3 is pulled out, as shown in FIG. Since the back plate 3c is rotated in accordance with the advance / retreat of the back plate 3c, the waste box 3 can be taken in and out without any trouble. Also, every time the waste box 3 is taken in and out, the connecting member 8 rotates, and the stirring action at this time exerts a function of flattening the shredded waste stored in the waste box 3 to some extent. It is possible to prevent inconveniences such as the rotation blade stopping due to clogging of the blade.

Next, another embodiment of the safety mechanism will be described with reference to FIG. In this embodiment, in the above embodiment in which the stoppers 7a and 7a are integrated by the connecting member 8, the connecting member 8 is omitted and the safety guides 7'are separately configured on the left and right. In this case, by adopting a configuration in which the shaft portions 7b, 7b do not come off from the guide bracket 2a, it is possible to restrict the inward deformation of the side walls 3a, 3a as in the above-described embodiment, and the waste box. You can also put in and take out 3 as you like.

In both of the above embodiments, the shredder 1
The lower cover 2 is configured differently from the safety guide 7, 7 '.
Is fixed to the guide bracket 2a of the lower cover 2, but when the lower cover 2 is integrated with the shredded portion 1 or the lower cover 2 is omitted, the safety guides 7, 7 '
Alternatively, the shredder 1 may be directly fixed to the shredded portion 1.

In both embodiments, the safety guide 7,
7'is provided corresponding to one place of the side wall 3a, but the corresponding place is not limited to this, and by providing a plurality of safety guides 7 and 7'along the drawer of the waste box 3, The deformation of the side wall 3a can be reliably regulated. However, when providing the safety guides 7 and 7'corresponding to one location of the side wall 3a as in both embodiments, the safety guides 7 and 7'may be provided so that the stopper 7a is located in the middle of the side wall 3a. preferable. The reason is that the middle portion of the side wall 3a of the waste box 3 is most likely to be deformed.

Further, the stopper 7a is at least the side wall 3
It suffices if it comes into contact with the upper edge of a.
Of course, the larger the contact area with the side wall 3a, the greater the effect of preventing the deformation of the side wall 3a.

[0014]

Since the present invention employs the above-described structure, even if a force is applied to the side surface of the waste box, the safety guide functions as a deformation restricting portion, so that the side wall of the waste box is prevented from being greatly deformed. It is possible and safe because the fingers do not enter the shredded part from between the waste box and the shredded part. Also, by making the safety guide a crank shape with a recess in the middle,
Every time the waste box is taken in and out, the shredded waste that has accumulated inside can be smoothed out, so the cause of failure such as the shredded waste being clogged in the rotary blade can be eliminated, and the efficiency of storing shredded waste in the waste box is improved. I was able to.
