Further, at both ends in the longitudinal direction of the intermediate member 13, notches 13 b and 13 b are provided for enabling the work when the base member 12 is screwed to the side plate 2.

  The coil springs 14 and 14 urge the base member 12 downward in the cover member 11, and are interposed between the base member 12 and the intermediate member 13. In that case, the upper part of each coil spring 14 is received by a resin spring receiving member 20.

  The spring shafts 15 and 15 are erected on the base member 12 at a predetermined interval in the longitudinal direction, and are inserted into the coil springs 14 and 14 to support them. Each spring shaft 15 includes a base portion 15a having the smallest diameter extending from the base member 12, a middle portion 15b having the largest diameter, and a head portion 15c having a middle diameter. In this case, the intermediate portion 15b is provided above the hole portion 13a provided in the intermediate member 13 and has a diameter larger than that of the hole portion 13a. The head portion 15 c protrudes from the hole portion 11 c of the upper surface 11 a of the cover member 11 and fits into the hole portion 6 a provided in the reinforcing plate 6, and is chamfered.

  The support shaft 16 is sandwiched between a pair of coil springs 14 and 14 and is erected on the base member 12, and an elongated resin lock member 17 that rotates in a horizontal plane is provided on the support shaft 16. On the other hand, the intermediate member 12 is provided with a hole portion 13c having a substantially rectangular shape in plan view that allows the lock member 17 to be inserted only in a predetermined direction indicated by a thin two-dot chain line in FIG. The lock member 17 and the hole 13c of the intermediate member 13 constitute a lock mechanism that locks the coil springs 14 and 14 in a compressed state with the upper surface 11a of the cover member 11 and the base member 12 approaching each other. The Further, the lower part of the lock member 17 is notched into a predetermined shape. Tool operation window portions 11f and 11f are provided on both side surfaces 11b and 11b of the cover member 11 so that a tool such as a hand driver for rotating the lock member 17 can be operated.

  The lid members 18 are made of resin that covers the openings at both ends of the cover member 11 and are detachably provided. That is, each lid member 18 includes a pair of upper engaging portions 18a and 18a extending in a substantially plate shape inwardly of the cover member 11, and a lower engaging portion 18b that is partially slit and has a substantially rectangular cross section. 18b, on the other hand, on the upper surface 11a of the cover member 11, engagement hole portions 11g... 11g into which protrusions in the vicinity of the tips of the upper engagement portions 18a, 18a are fitted are formed on both side surfaces of the cover member 11. 11b and 11b are provided with rail portions 11h and 11h extending along the longitudinal direction with which the lower engaging portions 18b and 18b are engaged.

  6 and 7 show the overturn prevention device 7 in a state where the coil springs 14 and 14 are extended until the urging force is reduced to a lower limit of a desired value. That is, this is because the fall prevention device 7 is mounted on the upper part of the side plate 2 of the storage shelf 1, and the lock member 17 is removed from the state shown by the solid line in FIG. 3 through the tool operation window portion 11 f of the cover member 11. By rotating 90 degrees as shown by the chain line and dropping it into the hole 13c of the intermediate member 13, the initial compression state of the coil springs 14, 14 is released, and the coil springs 14, 14 are in an appropriate stretched state. Thus, after a favorable biasing force is ensured between the storage shelf 1 and the reinforcing plate 6 and thus the ceiling surface Y, for example, the case where the storage shelf 1 is greatly depressed is shown. The coil springs 14 and 14 extend to the limit between the base member 12 fixed to the base plate 12 and the reinforcing plate 6 fixed to the ceiling surface Y, that is, the cover member 11 and the intermediate member 13.

  This limit expansion state is realized by large-diameter intermediate portions 15b and 15b provided on the spring shafts 15 and 15 penetrating the intermediate member 13 through the holes 13a and 13a abut on the intermediate member 13 from above. The intermediate portions 15b and 15b are located between the positions in the initial compressed state shown in FIGS. 4 and 5 and the positions in the limit extended state shown in FIGS. 6 and 7, for example, FIGS. 7, the coil springs 14, 14 press the upper surface 11 a of the cover member 11 against the reinforcing plate 6 satisfactorily. In this case, the intermediate portion 15b of the spring shaft 15 and the intermediate member 13 are in contact with each other so that the base member 12 does not protrude below a predetermined amount above the lower ends of the side surfaces 11b and 11b of the cover member 11. As the storage shelf 1 sinks, the heads 15c, 15c of the spring shafts 15, 15 erected on the base member 12 are slightly retracted toward the cover member 11 in the holes 6a, 6a of the reinforcing plate 6. is doing.

  6 and 7, when viewed from the direction of the arrow b, the upper edges of the bent portions 12a and 12a facing the upper side of the base member 12 are the lid members 18 and 18 as shown in FIGS. On the other hand, in the initial compressed state, as shown in FIGS. 4 and 5, when viewed from the direction of the arrow b, the bent portion 12a is positioned so as to be positioned below the lower edge with a predetermined gap β. , 12a, the dimensions of the bent portion 12a and the lid member 18, the arrangement position of the intermediate portion 15b in the spring shaft 15 and the like are set so that the lid members 18 and 18 hide the upper edge.

  Here, an example of a procedure for mounting the fall prevention device 7 to the storage shelf 1 will be described. First, the coil springs 14 and 14 shown in FIGS. The fall prevention device 7 in a state is fixed with screws Z1 and Z1. Thus, since the fall prevention device 7 in which the coil springs 14 and 14 are in the initial compressed state can be brought into the construction site from the factory, workability can be improved and a spring member extended to the site can be provided. Since it does not depend on the force of the installer, such as compressing it after installation, it is possible to always ensure a stable initial good tension force.

  Next, adjuster legs 4 and 4 are attached to the lower surface of each side plate 2. Then, the reinforcing plate 6 is attached to the ceiling surface Y via a double-sided adhesive tape to reinforce. By using a double-sided adhesive tape for this attachment, the ceiling surface Y will not be damaged like when screws or nails are used, and the ceiling surface Y is made of a material that does not work with screws or nails. It can also be installed when nails or nails are not allowed. When the ceiling surface Y is sufficiently strong, the reinforcing plate 6 may be omitted.

  Next, after the leg support member 5 is coupled to the adjuster legs 4 and 4 attached to each side plate 2 via, for example, a double-sided adhesive tape, the cover member 11 of the fall prevention device 7 mounted on the upper side of each side plate 2 is provided. The side plates 2 are erected so that the heads 15c, 15c of the spring shafts 15, 15 protruding from the upper surface 11a fit into the holes 6a, 6a of the reinforcing plate 6. Then, the screwing amount of the adjuster legs 4 and 4 to each side plate 2 is adjusted to bring the upper surface 11a of the cover member 11 into contact with the reinforcing plate 6 and the vertical of each side plate 2 is adjusted.

  In that case, since the head portion 15c of the spring shaft 15 is chamfered, the head can be smoothly fitted into the hole portion 6a of the reinforcing plate 6 to facilitate the work, and the reinforcing plate 6 around the hole portion 6a can be easily operated by the head portion 15c. Will not be damaged. Further, the wider the spacing between the pair of spring shafts 15, 15, the easier it is to fit into the holes 6 a and 6 a of the reinforcing plate 6. The smaller the diameter of the head portion 15c of the spring shaft 15 is, the smaller the diameter of the hole 6a of the reinforcing plate 6 is.

  In this way, each side plate 2 is set up vertically, and the shelf plates 3... 3 are installed between a pair of side plates 2 and 2 adjacent to each other, and the screwing amount of the adjuster legs 4. Then, after adjusting the horizontal and vertical of the entire storage shelf 1, for example, the lock member 17 is rotated 90 degrees through the tool operation window portion 11 f of the fall prevention device 7 by a hand screwdriver so as to have a predetermined orientation, and this is set as an intermediate member. 13 is dropped into the hole 13c, the locked state is released, and the coil springs 14 and 14 are extended. As a result, as shown by the arrow a and the thin two-dot chain line in FIGS. 4 and 5, the coil springs 14, 14 are connected to the base member 12 fixed to the upper surface of the protruding portion of the side plate 2, and the cover member. 11 is pressed against the reinforcing plate 6 and thus the ceiling surface Y, and the fall prevention device 7 is stretched between the storage shelf 1 and the ceiling surface Y.

  In that case, since the lower part of the lock member 17 is notched into a predetermined shape, the rotation becomes smooth when the locked state is released, and the lock member 17 easily falls into the hole 13c of the intermediate member 13. Further, since the lock member 17 is made of resin, the contact sound with the intermediate member 13 is relieved. And since it is the structure which can cancel | release the locked state of the two coil springs 14 and 14 all at once with the one lock member 17, there exists a merit which is excellent in workability | operativity. Furthermore, since the upper part of each coil spring 14 is received by the resin spring receiving member 20, the contact noise between the coil spring 14 and the intermediate member 12 is relieved.

  Then, the lid members 18 and 18 are fitted into both end portions of the cover member 11. In that case, the upper engagement portions 18a and 18a and the lower engagement portions 18b and 18b provided in each lid member 18, and the engagement hole portions 11g and 11g and the rail portions 11h and 11h provided in the cover member 11 Through the engagement, the lid member 18 is stably and detachably attached to the cover member 11.

  4 and 6, when the gap β is not observed when viewed from the direction of the arrow b, it means that the urging force of the coil springs 14 and 14 is well secured. Finish the work. When the gap β is observed, the screwing amount of the adjuster leg 4 may be adjusted so that the base member 12, that is, the upper surface of the protruding portion of the side plate 2 is moved upward until the gap β is not observed.

  By configuring as described above, first, since the fall prevention device 7 is installed on the protruding portion of the side plate 2 via the base member 12, the original storability of the storage shelf 1 can be maintained. In that case, since the base member 12 is provided with a stopper means to be described later for restricting the coil spring 14 as a spring member so that the base member 12 does not protrude below a predetermined amount above the lower end of both side surfaces 11b, 11b of the cover member 11, the cover member Both side surfaces 11b and 11b of 11 can always engage with the protruding portion of the side plate 2 from both sides, and the installation state of the cover member 11 and thus the installation state of the fall prevention device 7 are stabilized.

  Moreover, in this fall prevention apparatus 7, since the base member 11, the coil spring 14, the lock means mentioned later, and the stopper means are accommodated in the channel-shaped cover member 11, the appearance after installation is good.

  Since the coil spring 14 is interposed between the base member 12 that contacts the upper surface of the protruding portion of the side plate 2 and the upper surface 11a of the cover member 11 that contacts the ceiling surface Y, the fall prevention device 7 is connected to the storage shelf 1. If the initial compression state of the coil spring 14 is released via the locking means after the installation between the coil member 14 and the ceiling surface Y, the coil spring 14 is connected to the base member 12 and the storage shelf 1 and the upper surface 11a of the cover member 11 and the ceiling surface Y. The coil spring 14 can be prevented even if the ceiling surface Y or the floor surface X is uneven or the storage shelf 1 sinks due to the weight of the storage items. It is possible to ensure good stretchability by the urging force.

  In that case, since the fall prevention device 7 is installed in a portion of the storage shelf 1 called the side plate 2 that is strong against the load in the vertical direction, the stretchability is further ensured. By the way, in the conventional device of the method of installing the screw shaft into the storage shelf, it is necessary to provide a screwed part such as a demon nut on the storage shelf side, so when the screwed part is provided on the upper part of the side plate, It is not easy to cut the upper part of the side plate for adjusting the height of the storage shelf at the time of construction, and it is troublesome to provide a screwed part again after cutting. On the other hand, according to the present embodiment, it is not necessary to originally provide the screw-in portion, so that there is an advantage that it is possible to easily cope with the height adjustment of the side plate 2, that is, the height adjustment of the storage shelf 1.

  Next, since the spring shaft 15 as a pin member protruding from the upper surface 11a of the cover member 11 is provided, by providing a hole through which the spring shaft 15 is inserted on the ceiling surface Y side, this overturn at the time of construction is performed. Positioning of the prevention device 7 becomes easy, and workability is improved, for example, a fall is prevented. In particular, a reinforcing plate 6 provided with a hole 6a is provided on the ceiling surface Y side to prevent the storage shelf 1 from being overturned regardless of the strength state of the ceiling surface Y not only at the time of new construction but also at the time of reconstruction or moving. Can be achieved.

  Further, the coil spring 14 as a spring member is stably supported at a predetermined position on the base member 12 by the spring shaft 15, so that the vertical biasing force can be generated correctly. In that case, since the upper part of the spring shaft 15 is used as the pin member as described above, it is possible to reduce the number of parts and thus the cost.

  Further, by providing two coil springs 14 and two spring shafts 15, the coil springs 14, 14 can more uniformly support the upper surface 11 a of the cover member 11 and the base member 12, thereby providing a wider pressure receiving area. It can also be secured. Moreover, the spring shafts 15 and 15 protrude from the upper surface 11a of the cover member 11, and the head portions 15c of the spring shafts 15 and 15 engage with the holes on the ceiling surface Y side, that is, the holes 6a and 6a of the reinforcing plate 6. By doing this, rotation of this fall prevention device 7 with respect to the ceiling surface Y side is prevented, and workability at the time of construction is further improved.
