  EMBODIMENT OF THE INVENTION Hereinafter, the form for implementing the article | item fall prevention apparatus of the storage furniture of this invention is demonstrated in detail based on drawing.

  The storage furniture of the present invention can be a cabinet for an office as shown in FIG. 1, for example, two left and right side plates 1, a top plate (not shown), and a bottom plate (not shown). And a back plate 2 are combined to form a box-like body having an open front, provided with a plurality of storage spaces 3 in the upper part, and provided with a plurality of drawers 4 in the lower part.

  An article fall prevention device for storage furniture according to the present invention includes a pair of base members 5 attached to the front part of the inner surface of the both side plates 1, and a fall prevention member 6 pivotally supported by the base members 5 and rotated up and down. It is assumed.

  The base member 5 is provided with a shaft support hole 7 which is a long hole in the vertical direction such as an oval shape in the lower part and a substantially U-shaped shaft support groove 8 which is opened upward. The longitudinal length L of the shaft support hole 7 is substantially the same as the depth D of the shaft support groove 8 as shown in FIGS.

  The fall prevention member 6 includes a horizontal bar 9 and a rotating arm 10 provided at both ends of the horizontal bar 9. The rotating arm 10 is provided with a support shaft portion 10a at a base end and a support portion. 10b is provided at the rotating end. Further, the support shaft portion 10a of the rotating arm 10 is supported by the shaft support hole 7 of the base member 5 so as to be movable up and down. When the entire fall prevention member 6 is raised and pivoted upward, the support portion 10 b of the pivot arm 10 of the fall prevention member 6 is supported by the shaft support groove 8 of the base member 5. I try to do it. The rotating arm 10 has a screw hole 11a formed at the base end and a through hole 11b formed at the rotating end connected to each other through a slit 11c formed therebetween, and is supported by the screw hole 11a. A screw of a bolt that becomes the shaft portion 10a is screwed in, an end portion of the horizontal bar 9 that becomes the support portion 10b is projected into the through hole 11b, and the slit 11c is narrowed by the set screw 12, so that The support shaft portion 10a is firmly provided at the end, and the support portion 10b is firmly provided at the rotating end. The support portion 10b is integrated with the horizontal bar 9 as an end portion of the horizontal bar 9. However, the support portion 10b may be separate from the horizontal bar 9.

  The depth D of the shaft support groove 8 of the base member 5 is approximately twice as large as the thickness T of the horizontal bar 9 of the fall prevention member 6 as shown in FIGS. . Further, the shaft support groove 8 has a front wall 8a formed lower than the rear wall 8b, and the front wall 8a has a size approximately ½ times that of the rear wall 8b.

  In the storage furniture of the present invention, the storage space 3 is provided with a shelf board 3a, and a step 13 is provided at the front of the shelf board 3a. As shown in FIGS. 3, 6, and 9, the height H of the step 13 is approximately the same as or slightly larger than the thickness T of the horizontal bar 9 of the fall prevention member 6. In the state where the entire fall prevention member 6 is lowered and rotated downward, the horizontal bar 9 of the fall prevention member 6 is in a lowered state so as to be positioned immediately before the step 13. Yes.

  As shown in FIGS. 2 to 4, the storage device for falling articles of the storage furniture according to the present invention configured as described above is lowered by turning the entire fall prevention member 6 downward and turning it downward. As shown in FIG. 11, various articles such as document files and storage cases are stored in the storage space 3. In this case, since the horizontal bar 9 of the fall prevention member 6 is in a lowered state and is positioned immediately before the step 13 of the storage space 3, the horizontal bar 9 does not interfere with the various The article can be easily stored in the storage space 3 by being slid into the storage space 3.

  Next, the horizontal bar 9 of the fall prevention member 6 is picked with fingers, and as shown in FIGS. 5 to 7, the turning arm 10 of the fall prevention member 6 is turned 90 ° upward. Furthermore, while rotating 90 degrees from the state shown in FIGS. 5 to 7, the horizontal bar 9 is lifted so that the support shaft portion 10 a of the rotation arm 10 is moved from the lower position of the shaft support hole 7 of the base member 5 to the upper position. By raising, the support portion 10b of the rotating arm 10 is inserted into the support groove 8 of the base member 5, and is supported by the support groove 8 as shown in FIGS. Then, as shown in FIG. 12, the horizontal bar 9 of the fall prevention member 6 rises in front of various articles stored in the storage space 3. In this case, since the front wall 8a of the shaft support groove 8 is formed lower than the rear wall 8b, the horizontal bar 9 can be easily inserted into the shaft support groove 8.

  In this way, even when various kinds of articles stored in the storage space 3 are swung forward when the storage furniture is subjected to an earthquake or other vibration, the lower part of the front end of the article hits the horizontal bar 9 of the fall prevention member 6. Since it stops, the various articles stored in the storage space 3 do not fall or jump out of the storage space 3.

  Furthermore, in order to take out the various articles stored in the storage space 3, the horizontal bar 9 of the fall prevention member 6 in the state shown in FIGS. The moving arm 10 is rotated downward by its own weight, and the supporting shaft portion 10a of the rotating arm 10 is lowered from the upper position of the shaft supporting hole 7 of the base member 5 to the lower position, as shown in FIGS. Return to state. In this state, as described above, the horizontal bar 9 of the fall-preventing member 6 is in a lowered state and is positioned immediately before the step 13 of the storage space 3 and is accommodated in the step 13. Since the bar 9 can be pulled out without being disturbed, the various articles can be easily taken out from the storage space 3.
