In addition to the fall prevention member 10 described above, the fall prevention device 20 includes a fall prevention cage 21 attached to the basket attachment portion 13, and a fixing member that is fixed to a column or frame plate of a shelf such as a bookshelf and pivotally supports the fall prevention member 10. 22.

  As described above, the fall prevention rod 21 is fitted so as to cover the outer periphery of the rod attachment portion 13. The fall prevention jar 21 is a member that is disposed on the front surface of a load such as a book mounted on a shelf of a bookshelf and directly regulates the pop-out of the load. Therefore, the length of the fall prevention basket 21 is adjusted in accordance with the length of the shelf board in the horizontal direction. When viewed from the center of the fall prevention rod 21, a pair of symmetrical fall prevention members 10 are attached to the left and right ends of the fall prevention rod 21.

  The fixing member 22 pivotally supports the fall prevention tool 20 with the rotary shaft portion 12 so that the hook mounting portion 13 and the fall prevention rod 21 of the main body portion 11 can be moved between the upper position and the lower position. .

Is provided with a concave fixing portion 22c that is hooked on the fitting portion 15 and fixed in the vertical and horizontal directions at the upper position.

  The mounting portion 22a can adopt any known configuration as long as it can be fixed to the column C. In this embodiment, as shown in FIG. 3, the shelf plate R provided on the side surface of the column C is variable. The fixing member 22 is fixed by hooking a key-shaped hooking member indicated by a broken line in the drawing using a plurality of mounting holes CH for mounting in a formula. Such an attachment method uses the attachment hole CH provided with the support column C effectively, and even when the shelf plate having a variable height is shifted and installed, the height of the fixing member 22 is adjusted accordingly. It is possible to easily change the length. Further, since the attachment portion is hidden on the side surface of the support column C, there is no inconvenience in appearance.

  However, as described above, the fall prevention device of the present invention is not limited to such an aspect, and as shown in Patent Document 1, a method of fixing to the front side of the support by welding or the like can also be employed. .

  The vertical hole 22b is a vertically long hole provided below the fixing member 22, and supports the rotating shaft portion 12 so as to be rotatable, and when the fall prevention member 10 is positioned above, the fixing portion 22c described later.

A triangular pocket 22d is formed to fit the triangular piece 15a from above. The shape of the triangular pocket 22d has a shape protruding downward in a triangle so as to receive the triangular piece 15a of the fitting portion 15 described above.

  Moreover, although this fixing | fixed part 22c is a concave shape opened upwards, when the fall prevention rod 21 is fixed in an upper position, unless the fall prevention rod 21 is once moved to the support | pillar C side, it will not come out as it is. Thus, it has the engagement piece 22e which protruded to the support | pillar C side. That is, the fixing portion 22c has an opening for releasing the main body portion 11 with respect to the column C direction, which is the direction in which the biasing portion 14 is biased, and is upward and in a direction opposite to the biasing direction of the biasing portion 14. Is designed to be fixed.

[1-2. Action]
The operation of the fall prevention member 10 and the fall prevention tool 20 of the present embodiment configured as described above will be described.
As shown in FIG. 3, the fall prevention member 10 of the present embodiment is composed of a pair of symmetrical left and right, and the fixing member 22 is attached in a state where a fall prevention rod 21 having a predetermined length is attached to the rod attachment portion 13. And fixed to the left and right columns C1 and C2.

  More specifically, first, the fixing member 22 is fixed by hooking the hooking member of the mounting portion 22a into the mounting hole CH provided in advance in the columns C1 and C2. Subsequently, in the rotation shaft portion 12 of the fall prevention member 10, the bolt 12a is inserted into the shaft hole 11a provided in the rotation shaft portion 12 portion, and the nut 12b is inserted into the vertical hole 22b of the fixing member 22, and the bolt 12a Tighten the screws. As a result, the fall prevention member 10 is pivotally supported with respect to the fixing member 22, and the fall prevention member 10 and the fall prevention rod 21 are suspended below the fixing member 22 as shown in FIG. 3. It becomes a state.

  In this state, the fall prevention basket 21 does not interfere with the shelf board R, and can be freely taken out and mounted with a new article mounted on the shelf board R.

  From the state of FIG. 3, as shown in FIG. 4, the fall prevention member 10 is rotated upward about the rotation shaft portion 12. At this time, by simultaneously moving the rotary shaft portion 12 to the upper end position in the vertical hole 22b of the fixing member 22, the rod attachment portion 13, the fitting portion 15, and the fall prevention rod 21 are fixed to the fixing portion 22c of the fixing member 22. The fitting portion 15 can be fitted into the concave opening of the fixing portion 22c.

  From the state of FIG. 4, as shown in FIG. 5, the fall prevention rod 21 is fitted into the concave opening of the fixing portion 22 c. The situation at this time will be described with reference to FIG. FIG. 2A shows a state in which the rotation shaft portion 12 of the fall prevention member 21 shown in FIG. 4 is located at the upper end in the vertical hole 22b of the fixing member 22, and the fitting portion 15 is FIG. 2B shows a state where the fitting portion 15 shown in FIG. 5 is fitted into the concave opening of the fixing portion 22c.

  As described above, the main body portion 11 of the fall prevention member 10 is provided with the urging portion 14 that urges the other surface in a direction away from the side surface. On the other hand, the fitting portion 15 includes a triangular piece 15 a that protrudes downward, and a step portion 15 b that forms a step portion on the side surface of the base portion of the flange attachment portion 13. Furthermore, an engagement piece 22e that protrudes toward the column C and engages with the step portion 15b of the fitting portion 15 is provided at the opening portion of the fixed portion 22c.

  Here, since the urging | biasing part 14 protrudes in the side surface side of the main-body part 11 if the main-body part 11 is a natural state, the fitting part 15 cannot be inserted with respect to the fixing | fixed part 22c. Therefore, when the fitting portion 15 is fitted into the fixing portion 22c, the main body portion 11 is moved in the column C direction against the urging force of the urging portion 14 as shown by the white arrow in FIG. In this state, the fall prevention member 10 is lowered downward in the figure so that the rotary shaft portion 12 moves to the lower end of the vertical hole 22b.

  In this manner, when the main body 11 is stopped from being pressed in the direction of the column C in a state where the rotary shaft 12 is positioned at the lower end of the vertical hole 22b, the main body 11 is attached as shown in FIG. Due to the urging force of the urging portion 14, it is returned to the right in the figure, the triangular piece 15 a of the fitting portion 15 is fitted with the fixed portion 22 c, and the step portion 15 b is engaged with the engaging piece 22 e, so 21 is held vertically and horizontally at the upper position.

  In this state, the fall prevention basket 21 interferes with the shelf board R, and the removal of the mounted article mounted on the shelf board R and the loading of a new article are restricted. Therefore, when taking out the load mounted on the shelf board R, it is necessary to return the fall prevention rod 21 to the state shown in FIG.

[1-3. effect]
According to the fall prevention member and fall prevention tool of the present embodiment as described above, as shown in FIG. When the fall prevention rod 21 is urged to the side opposite to the column C when inserted into the fixing portion 22c of the fixing member 2, the fall prevention rod 21 is fitted into the fixing portion 22c.

  Therefore, even when vibration or shaking such as an earthquake occurs, the fall prevention rod 21 is fixedly held in the fixing portion 22c by the urging force of the urging portion 14, and thus jumps out from the opening of the fixing portion 22c. Thus, the fall prevention gutter 21 does not come off.

  On the other hand, the fitting part 15 is released from the state in which the fitting part 15 is fitted to the fixing part 22c and the fall prevention bar 21 is fixed and held so that the fall prevention bar 21 is positioned below as shown in FIG. Also when moving, the fall prevention gutter 21 can be removed easily. That is, if the fall prevention rod 21 is pushed in the column C direction with a force larger than the urging force of the urging portion 14, the fitting between the triangular piece 15a and the fixing portion 22c of the fitting portion 15 and the step portion 15b and the engaging piece. The main body 11 moves upward along the downward triangular side of the triangular piece 15a and the fall prevention rod 21 can be released. Therefore, the holding of the fall prevention basket 21 prevents the fall of the article mounted on the shelf, and the release prevention basket 21 can be easily released at the time of use, so that the convenience is high.

  Further, the urging portion 14 is constituted by a plate spring branched from the main body portion 11 into a plate shape, and further, the urging portion 14 is provided by forming the main body portion 11 from a synthetic resin and molding it integrally therewith. In addition, it is easy to process the fall prevention member, and a sense of unity can be formed in terms of design.

[2. Other Embodiments]
The present invention is not limited to the aspects shown in the present embodiment, and includes, for example, the following aspects. In the above-described embodiment, the fall prevention member 10 is provided with the fitting portion 15 and the fixing portion 22c of the fixing member 22 corresponding to the fitting portion 15, and the triangular piece 15a and the fixing portion 22c are fitted to each other. 15b and the engagement piece 22e are engaged so that the fitting portion 15 can be held in the vertical and horizontal directions in the fixed portion 22c. However, the present invention is not limited to such an embodiment, and can be realized with a simple configuration in which the fixing member 22 is a pocket having an open upper surface and the fall prevention rod 21 is inserted into the pocket as in the prior art. Is possible.

  Even in such a configuration, the lateral movement of the fall prevention rod 21 in the pocket is restricted by the urging force of the urging portion 14 provided in the main body 11, so that the vibration or shaking caused by an earthquake or the like is prevented. On the other hand, it is possible to prevent the fall prevention jar 21 from coming off.

  With such a configuration, it is possible to add a function that is difficult to come off to the conventional fall prevention device by replacing only the fall prevention member with the conventional fall prevention device.

  Further, in the present embodiment, the fall prevention member 10 and the fall prevention basket 21 which are configured separately can be integrally formed. However, when formed integrally in this way, unlike the case where it is configured as a separate body, the fall prevention basket 21 cannot be exchanged, so that the fall prevention basket 21 cannot be used in accordance with the size of the bookshelf.

  In the present embodiment, the urging portion 14 is configured by a leaf spring in which a part of the main body portion 11 made of a synthetic resin is protruded in the side surface direction, but this shows an optimal embodiment, If there is a function to urge the other surface in a direction away from the side surface when another surface comes into contact with the side surface, use other springs in a broad sense, such as providing a coil spring or a block-like elastic body. It is also possible to use it.
