  The fall prevention device includes a pair of left and right base members 1 and a fall prevention bar 2.

  The base member 1 is a thick member, and has a shaft support hole 3 extending in a long hole shape from a substantially central portion to a lower portion. A groove-like support portion 4 is formed immediately above the shaft support hole 3, that is, from the substantially central portion to the upper portion of the base member 1, and the upper end of the support portion 4 is opened.

  Such a base member 1 can be, for example, a resin molded product.

  The fall prevention bar 2 is a member having a substantially U-shape formed by left and right side pieces 21 and a horizontal piece 22. It can be formed of a wire such as metal. From the middle to the lower side of the left and right side pieces 21 is a bent portion 23 that is bent inward in a substantially U-shape. A distal end portion 23 a that faces the outside of the bent portion 23 is rotatably fitted in the shaft support hole 3 of the base member 1, and the fall prevention bar 2 is pivotally supported by the left and right base members 1.

  Such a fall prevention device can be attached to a cabinet such as a cupboard or a bookshelf as follows.

That is, the base member 1 is attached to the inner surface front side of the left and right side plates 6 of the cabinet 5. The attachment can be used dowel holes 7 formed in the right and left side plates 6 of the cabinet 5, dowels 8 on the back of the base over the scan element 1 that has been erected. By fitting the dowel 8 into the dowel hole 7, the base member 1 is attached to the front side of the inner surface of the left and right side plates 6 of the cabinet 5. For stable fixing of the base member 1, the screws 9 may be screwed into the left and right side plates 6 of the cabinet 5 at positions different from the dowels 8 so that the base member 1 does not rotate around the dowels 8. it can. The screw 9 can be replaced with the dowel 8, and the attachment of the base member 1 to the left and right side plates 6 of the cabinet 5 is stabilized by fitting the two dowels 8 into the dowel holes 7 at different positions.

  In this way, the fall prevention bar 2 is attached to the base member 1 attached to the left and right side plates 6 of the cabinet 5. That is, the fall prevention bar 2 is bent slightly due to its elasticity, and the distal end portion 23 a facing the outer side of the bent portion 23 formed on the left and right side pieces 21 is fitted into the shaft support hole 3 of the base member 1. In this case, the end face cap 10 can be attached to the distal end portion 23a so that the shaft support by the shaft support hole 3 is smooth.

  Since the fall prevention device can be attached to the cabinet 5 as described above, the attachment is easy and can be retrofitted to the existing cabinet 5.

  FIG. 2 shows a state in which articles such as tableware and books are prevented from falling or jumping out by the fall prevention device. In order to prevent the article from falling or jumping out, the fall prevention bar 2 is disposed in a standing state at the front opening of the cabinet 5. In this standing state, the distal end portion 23a of the bent portion 23 of the fall prevention bar 2 is located at the lower end of the shaft support hole 3 of the base member 1, and the upper side from the middle of the left and right side pieces 21 of the fall prevention bar 2 is This is realized by being inserted into the support portion 4 of the base member 1. Since the upper side of the middle of the left and right side pieces 21 is inserted into the support portion 4 of the base member 1, the fall prevention bar 2 is held in an upright state, and this state can be maintained stably. The fall prevention bar 2 does not rattle.

  When an article such as tableware or a book is stored in the cabinet 5 and is taken out, if the fall prevention bar 2 is in an upright state, it becomes an obstacle to storing and taking out the article. Therefore, the fall prevention bar 2 is moved downward. This state is shown in FIG.

  Since the shaft support hole 3 of the base member 1 has a long hole shape, the distal end portion 23 a of the bent portion 23 formed on the left and right side pieces 21 of the fall prevention bar 2 is within the length range of the shaft support hole 3. Can be moved to. In the standing state of the fall prevention bar 2, the distal end portion 23 a of the bent portion 23 is at the lower end of the shaft support hole 3 as described above. Therefore, the fall prevention bar 2 is moved upward until the tip 23a of the bent portion 23 reaches the upper end of the shaft support hole 3. By this movement, the upper side from the middle of the left and right side pieces 21 of the fall prevention bar 2 is taken out from the support portion 4 of the base member 1. Since the tip 23 a of the bent portion 23 of the fall prevention bar 2 is located in the shaft support hole 3 of the base member 1, the fall prevention bar 2 can be rotated forward of the cabinet 5. Therefore, the fall prevention bar 2 is rotated forward of the cabinet 5 and moved downward. With this movement, the tip 23 a of the bent portion 23 of the fall prevention bar moves along the shaft support hole 3 to the lower end of the shaft support hole 3. Eventually, as shown in FIG. 4, the fall prevention bar 2 falls and the front opening of the cabinet 5 is all opened. It becomes possible to store and take out articles such as tableware and books.

  When the fall prevention bar 2 is set again, an operation reverse to the above may be performed. Since the distal end portion 23a of the bent portion 23 formed on the left and right side pieces 21 of the fall prevention bar 2 is located at the lower end of the shaft support hole 3 of the base member 1, in this state, the fall prevention bar 2 Can be rotated upward. When the fall prevention bar 2 comes to the front surface of the cabinet 5, the fall prevention bar 2 is pulled up, and the upper side of the middle of the left and right side pieces 21 is positioned above the support part 4. Then, the fall prevention bar 2 is pulled down. The upper side of the middle of the left and right side pieces 21 of the fall prevention bar 2 is inserted into the support part 4, and the fall prevention bar 2 is held in an upright state.
