Description

  The present invention relates to an entrainment prevention device that is attached to a shredder and prevents entrainment of foreign matter into a cutting opening.

  Conventionally, a shredder has been used as means for cutting unnecessary paper and the like. This shredder stores a cutting port for loading cut sheets such as unnecessary paper, a cutter for cutting the loaded cut sheets, and paper cutting waste cut by several millimeters by the cutter. It is roughly divided into scraps.

  Conventionally, such a shredder has been mainly used in large-scale offices, but in recent years, in particular, from the viewpoint of personal information protection and the like, so-called SOHO and popularization in homes are remarkable. However, accompanying this, painful accidents in which infants put their fingers in the shredder cuts and cause serious injuries have occurred frequently. On the other hand, a shredder or the like for the purpose of preventing such an accident is described in, for example, Patent Document 1 and Patent Document 2 below.

  In Patent Document 1, “when the thickness of the insert inserted along the paper tray is larger than a certain value, an insertion abnormality detecting means for detecting the state is provided in the vicinity of the paper feed opening. There is disclosed a “safety mechanism for a shredder device” characterized in that means for stopping the drive of the paper cutter is provided when the abnormality detecting means detects an abnormality of the insert. As a result, “It is possible to prevent an unexpected accident that a finger is caught in the vicinity of the paper feeding port and damaged while using the shredder device”.

  Further, Patent Document 2 states that “in the shredder provided with a guide member for guiding the cut paper to the cut paper input port in the vicinity of the upper part of the cut paper input port of the main body, A shredder is disclosed in which the cut paper input port is closed by a guide member by closing the upper side of the cut paper input port. " As a result, “the guide member doubles as the lid of the shredder body. Therefore, when the guide member is not in use, the guide member is closed on the cut paper input port, so that the cutting cutter roller is closed and safety is improved. Is done. "

  However, the invention disclosed in Patent Document 1 uses a pressure sensor, a detection switch, or the like to electrically turn on and off the paper cutter drive motor, and tends to be large and expensive. On the other hand, although the invention disclosed in Patent Document 2 does not perform electrical control, it is merely a structure in which the cut paper input port is closed with a guide member only when not in use. May have been involved. Further, it is troublesome to jump up the guide member upward at the time of cutting. Furthermore, the safety mechanism disclosed in these patent documents cannot be retrofitted to existing shredders.

  The present invention solves the above-described problems, and provides an entrainment prevention device that can prevent entrapment of foreign matters during cutting and can be easily attached to a shredder having various shapes.

  In order to solve the above-mentioned problem, a device for preventing a foreign object from being caught in a cutting opening by attaching a cutting opening for inserting a sheet to be cut to a shredder provided on the upper surface, which is long A vertical guide body, and a front and rear plate-like swing body supported on the lower parts of both front and rear sides of the vertical guide body so as to be swingable around a left and right fulcrum. The vertical guide body penetrates vertically. A slit-shaped sheet guide hole that extends to the left and right, and the front and rear plate-like swing bodies spread along the shredder top surface, the sheet to be cut inserted from the top opening of the sheet guide hole is cut A shredding prevention device for a shredder that is mounted on the shredder with the lower end opening of the sheet guide hole and the cutting opening of the shredder facing each other so as to be guided by the mouth.

The vertical guide body has a slit-like sheet guide hole penetrating vertically, and the sheet to be cut is introduced from the upper end opening of the sheet guide hole and guided to the cutting opening. With this configuration, since the place where the sheet to be cut is put away from the cutting opening, it is safe that foreign substances such as fingers are not caught in the cutting opening.
Further, since the sheet guide hole has a slit shape, foreign matters such as a finger are less likely to enter the sheet guide hole itself, and the foreign matter is less likely to be caught in the cutting hole, which is safer.
Further, since the front and rear plate-like swing bodies are swingable, the swing bodies can be arranged in accordance with the upper surface shape of the shredder, and can be easily retrofitted to the shredders having various upper surface shapes.
For mounting on the shredder, the lower surface of the plate-like swing body may be bonded to the upper surface of the shredder, or a long rubber body as will be described later may be used to press the lower surface of the plate-like swing body against the upper surface of the shredder.

  It can be set as the entanglement prevention apparatus by which the vertical guide body is comprised with the material with transparency. Thereby, it becomes easy to make the lower end opening part of a sheet guide hole and the cutting opening of a shredder oppose up and down, and an entrainment prevention apparatus can be retrofitted more easily.

  It is also possible to provide an entrainment prevention device configured such that the vertical height of the slit-shaped sheet guide hole is 3 cm or more and the depth in the front-rear direction is 0.8 cm or less.

  It is preferable that the height of the sheet guide hole in the vertical direction is 3 cm or more because the distance between the upper end opening of the sheet guide hole and the cutting opening is increased, and safety can be secured. The height in the vertical direction of the sheet guide hole is more preferably 3.5 cm or more, and most preferably 4 cm or more. The upper limit of the height in the vertical direction of the sheet guide hole is not particularly limited in consideration of safety, but if it is too high, it is not realistic because it is bulky or looks bad. Considering this, the height of the sheet guide hole in the vertical direction is preferably 30 cm or less, more preferably 20 cm or less, and most preferably 10 cm or less. On the other hand, when the depth in the front-rear direction of the sheet guide hole is 0.8 cm or less, it is preferable that foreign matters are less likely to enter the sheet guide hole, and safety can be secured. The depth in the front-rear direction of the sheet guide hole is more preferably 0.6 cm or less, and most preferably 0.4 cm or less, considering the thickness of the infant's finger and the like. The depth lower limit value in the front-rear direction of the sheet guide hole is not particularly limited in consideration of safety, but if it is too small, it becomes difficult to insert the sheet to be cut. Considering this, the depth in the front-rear direction of the sheet guide hole is preferably 0.1 cm or more, more preferably 0.2 cm or more, and most preferably 0.3 cm or more.

  A sheet guide is provided on the front side of the upper end surface of the vertical guide body so that the sheet to be cut can be easily put into the upper end opening of the sheet guide hole. It is also possible to provide an entrainment prevention device that is formed to be substantially the same width as the width and that is erected on the vertical guide body with the upper portion inclined toward the front side.

  By erecting the sheet guide, it becomes easier to insert the sheet to be cut into the slit-shaped sheet guide hole, and the efficiency of the cutting work is improved. Further, the sheet guide is erected on the vertical guide body with the upper portion thereof inclined toward the front side, so that the leading edge of the sheet to be cut is easily guided to the slit-shaped sheet guide hole.

  The sheet guide may be an entrainment prevention device in which side guides are provided upright on both left and right ends of a guide surface facing obliquely upward. Thereby, it becomes easier to put the cut sheet into the sheet guide hole.

  The sheet guide may be a wrapping prevention device having chamfered corners at the left and right corners of the upper end. This makes it difficult to get injured at the upper corners of the seat guide. In particular, considering the case where an entrainment prevention device is attached to a shredder in a home with infants, the upper end of the seat guide is located just near the infant's face, so if the left and right corners are square, the eyes will poke, etc. It is very dangerous. However, by adopting the above configuration in which this portion is chamfered, the face and the like are hardly injured.

  The front and rear plate-like swing bodies can be an entrainment prevention device that is a double laminated structure in which a sponge material is attached to the lower surface of a plate material. Thereby, the sponge body is reliably deformed according to the top surface shape of the shredder, and can be attached to the shredders of various top surface shapes more easily and firmly.

  The front and rear plate-like swing bodies are supported by the vertical guide body in such a state that their lower surfaces are substantially in the same plane as the lower end surface of the vertical guide body in a state where they are spread in a wing shape so as to be horizontal. It can also be set as the entanglement prevention apparatus currently used.

  When a large gap space is created between the lower end surface of the vertical guide and the shredder cut-out with the entanglement prevention device attached to the shredder, the infant inserts his / her fingers through the openings at both ends of this gap space and the cut-off opening There was a possibility of getting involved. By setting it as the said structure, it becomes difficult to produce a big clearance space between the lower end of a vertical guide body, and the cutting opening of a shredder, and becomes a safer entanglement prevention apparatus.

  Front and rear locking parts provided on the front and rear plate-like swing bodies, and long rubber bodies each provided with locked parts for connecting to the front and rear locking parts are provided at both ends, and the long rubber body is a shredder Connect the locked parts at both ends of the long rubber body to the locking parts of the front and rear plate-like swinging bodies through the lower surface side of the long rubber body so that the long rubber body embraces the shredder in a stretched state By doing so, it is also possible to prevent entrainment to be attached to the shredder. Here, the “connection” in this specification refers to the case where the locked portion is directly locked to the locking portion, or the locking portion and the locked portion are indirectly locked using a connecting member. It is a concept that includes.

  Thereby, it can be attached to the shredder without bonding the lower surface of the plate-like swing body and the upper surface of the shredder, and the entanglement preventing device can be easily removed.

  The front and rear locking portions provided on the front and rear plate-like swing bodies, the long rubber bodies provided with the locked portions for connecting to the front and rear locking portions, respectively, and the shredder mounting surface An anti-slip rubber sheet is laid, and the anti-slip rubber sheet is provided with parallel slits in the front-rear direction in which long rubber bodies can be inserted, respectively, with both ends of the long rubber body facing upward and below the anti-slip rubber sheet. The locking parts on both ends of the long rubber body are engaged with the locking parts of the front and rear plate-like swing bodies in the state where the shredder is placed on the anti-slip rubber sheet through which the long rubber body penetrates. It can also be set as the entanglement prevention apparatus with which a long rubber body is mounted | worn with a shredder by embracing a shredder in a stretched state.

  Thereby, it can be attached to the shredder without bonding the lower surface of the plate-like swing body and the upper surface of the shredder, and the entanglement preventing device can be easily removed. Further, the presence of the anti-slip rubber sheet makes it difficult for the shredder to slip on the mounting surface, and the shredder can be firmly installed on the mounting surface.

  According to the present invention, it is possible to provide an entrainment prevention device that can prevent entrainment of foreign matters during cutting and can be easily retrofitted to a shredder having various shapes.
