[0014] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0015] FIG. 1 is an overall view of an article storage shelf 2 to which a belt hook 1 and an article fall prevention device 10 are attached.

[0016] The item storage shelf 2 has multiple support pillars P (two or more on each of the front and rear sides) set up at intervals, and shelf members T on which items W are placed are supported between each of the two support pillars P on the front and rear sides and fixed to the support pillars P, and an item fall prevention device 10 is attached to the front of this item storage shelf 2.

[0017] 1 and 2, the support pillar P has a generally U-shaped cross section and includes a front wall Pc and left and right side walls Pa, which are folded back to form a narrow back wall Pb. The front wall Pc and the left and right side walls Pa are provided with a number of locking holes 3 arranged in a vertical direction for locking other components and for weight reduction.

[0018] FIG. 1 shows an article fall prevention device 10 using belt hooks 1A, 1B, 1C and a belt B according to the first to third embodiments.

[0019] The lower left of Figure 1 shows a belt hook 1A of the first embodiment, which retracts the belt B from the stored item facing position α to the front of the lower item storage shelf 2, and the upper left of Figure 1 shows a belt hook 1A of the first embodiment, which retracts the belt B from the stored item facing position α to an upper non-stored item facing position β.

[0020] The lower right of Figure 1 shows a second embodiment of a belt hook 1B that retracts the belt B from the stored item facing position α to the front of the lower item storage shelf 2, and the upper right of Figure 1 shows a third embodiment of a belt hook 1C that retracts the belt B from the stored item facing position α to an upper non-stored item facing position β.

[0021] A belt hook 1A of the first embodiment and an article fall prevention device 10 using the same are shown in FIGS.

[0022] The belt hook 1A has a belt hook Sm that is arranged along the side edge of the front wall Pc of the support P and hooks the belt end Ba in a manner that allows the belt end Ba to be positioned up and down, a first attachment part S1 that is provided at one end of the belt hook Sm and attached to the support P, and a second attachment part S2 that is provided at the other end of the belt hook Sm and attached to the support P.

[0023] In addition, the belt hanging portion Sm has a length that is more than twice the width of the belt B to be hung thereon, and at least one of the first mounting portion S1 and the second mounting portion S2 is fixed to the support P using the locking hole 3.

[0024] The belt loop Sm, first mounting portion S1, and second mounting portion S2 are formed from a single rod material, preferably a round wire material (wire, plated wire material) with a diameter of 3 to 6 mm. The length of the belt loop Sm is preferably 2 to 5 times the width of the belt B.

[0025] The first attachment portion S1 has a front horizontal edge portion a that bends from one end of the belt hanging portion Sm and crosses the front wall Pc of the support P, a side horizontal edge portion b that bends from the front horizontal edge portion a and crosses the side wall Pa of the support P, and a clamping edge portion c that bends from the side horizontal edge portion b and wraps around the back wall Pb of the support P and clamps the support P together with the front horizontal edge portion a.

[0026] The second mounting portion S2 is bent from the other end of the belt hook portion Sm and engages the side wall Pa of the support P. It has a side half-side portion d that crosses to the locking hole 3, and a retaining side portion e that bends from this side half-side portion d and enters the locking hole 3 to prevent it from coming off. This second mounting portion S2 is fixed to the support P using the locking hole 3.

[0027] 1, 2, 3(a), 4 and 5 show the belt hook 1A attached to the left support P as viewed from the storage shelf 2, and the oblique views of FIGS. 2 and 3 show the support P as viewed from above and behind.

[0028] The procedure for removing the belt hook 1A is as follows: when the clamping edge c of the first mounting part S1 is removed from the pillar P from the pillar mounted state shown in Figure 3(a), it becomes the released state shown in Figure 3(b), and then when the first mounting part S1 is further rotated away from the pillar P, it becomes the state shown in Figure 3(c) and then the state shown in Figure 3(d), and from that state, it is twisted or the angle relative to the pillar P is changed to remove the retaining edge e of the second mounting part S2 from the locking hole 3 as shown in Figure 3(e).

[0029] The procedure for attaching the belt hook 1A is the reverse of the removal procedure. First, insert the retaining edge e of the second attachment part S2 into the locking hole 3 in the side wall Pa of the support P (Fig. 3(e)}. Then, rotate the first attachment part S1 so as to press down, bringing the tip of the retaining edge e into contact with the inner surface of the side wall Pa (Figs. 3(d)(c)}. Then, fit the first attachment part S1 to the support P by bringing the front horizontal edge a of the first attachment part S1 closer to the front wall Pc of the support P and bringing the side horizontal edge b into contact with the side wall Pa. During this fitting, the clamping edge c elastically deforms and comes into contact with the back wall Pb of the support P, so that the clamping edge c, together with the front horizontal edge a, clamps the support P (Fig. 3(a)).

[0030] The belt hook 1A has the first attachment part S1 located on the lower side and the second attachment part S2 located on the upper side, and the belt hook part Sm is positioned along the right edge of the front wall Pc of the left support pillar P. However, when attaching a belt hook 1A of the same shape to the right support pillar P, the belt hook part Sm needs to be positioned along the left edge of the front wall Pc of the right support pillar P, so the right belt hook 1A will be upside down compared to the left belt hook 1A.

[0031] In the lower left of Figure 1, two belt hooks 1A are prepared, and the first belt hook 1A on the left is attached to the first support post P with the first attachment part S1 facing downward, and the second belt hook 1A on the right is attached to the second support post P with the first attachment part S1 facing upward, and both belt ends Ba of belt B are hung on the belt hook parts Sm of both belt hooks 1A.

[0032] Both belt ends Ba of the belt B are sewn into a cylindrical shape, and each is fitted into the belt hooking portion Sm of the belt hook 1A, and can move within the range of the vertical length of the belt hooking portion Sm.

[0033] In the lower left of Figure 1, the belt hooking portions Sm of the left and right belt hooks 1A extend upward from a height that overlaps with the shelf member T, so when the belt B is positioned at the lowest position of the belt hooking portion Sm, the belt B overlaps with the shelf member T and is not facing the article W. This position is the non-facing position β for stored articles. In this state, the article W can be placed on and taken out of the shelf member T.

[0034] When the belt B is moved upward from the lowest position of the belt hooking portion Sm, the belt B is placed in a position α facing the stored article W, thereby preventing the article from falling off the shelf member T.

[0035] When the height of the articles W stored on the shelf member T is approximately uniform, the upper side of the stored articles W also becomes the non-stored article facing position β.

[0036] In the upper left of Figure 1, the belt hooking portion Sm of the left and right belt hook fittings 1A is located above the shelf member T. When the belt B is positioned at the top of the belt hooking section Sm, the belt B is in a non-stored item facing position β where it does not face the item W, making it possible to put the item W in and take it out of the shelf member T.

[0037] When the belt B is moved downward from the top of the belt hook Sm, the belt B is placed in a position α facing the stored article W, thereby preventing the article from falling off the shelf member T.

[0038] The belt B has a belt end Ba, which has been sewn into a cylindrical shape, directly fitted into the belt hooking portion Sm of the belt hooking fitting 1A. However, as shown in FIG. 7, a hook fitting F may be attached to the belt end Ba and engaged with the belt hooking portion Sm.

[0039] The belt B may be a belt with a buckle that allows for length adjustment, or a belt with rubber woven into it that is elastic and stretchable.

[0040] In the first embodiment, only one type of belt hook 1A is shown, and "the first belt hook 1 on the left side is attached to the first support pillar P with the first attachment part S1 facing downward, and the second belt hook 1 on the right side is attached to the second support pillar P with the first attachment part S1 facing upward," but it is also possible to manufacture two types of belt hooks 1A with symmetrical shapes so that "the first belt hook 1A on the left side is attached to the first support pillar P with the first attachment part S1 facing downward, and the second belt hook 1A on the right side is also attached to the second support pillar P with the first attachment part S1 facing downward."

[0041] A belt hook 1B of the second embodiment and an article fall prevention device 10 using the same are shown at the bottom right of FIG.

[0042] The belt hook 1B has a belt hook Sm that runs along the side edge of the front wall Pc of the support P and hooks the belt end Ba in a vertically changeable position, a first attachment part S1 that is provided at one end of the belt hook Sm and attached to the support P, and a second attachment part S2 that is provided at the other end of the belt hook Sm and attached to the support P, and the belt hook Sm, first attachment part S1 and second attachment part S2 are formed from a single round wire (wire, plated wire).

[0043] In addition, the belt hanging portion Sm has a length that is more than twice the width of the belt B to be hung thereon, and at least one of the first mounting portion S1 and the second mounting portion S2 is fixed to the support P using the locking hole 3.

[0044] The first attachment portion S1 has a side horizontal edge portion b that bends from one end of the belt hanging portion Sm and crosses the side wall Pa of the support P, a back horizontal edge portion f that bends from this side horizontal edge portion b and crosses the back wall Pb of the support P, and a clamping edge portion c that bends from this back horizontal edge portion f to reach the side wall Pa of the support P and clamps the support P together with the side horizontal edge portion b.

[0045] Similar to the belt hook 1A, the second attachment part S2 has a side half-edge part d that bends from the other end of the belt hook part Sm and crosses the side wall Pa of the support P up to the locking hole 3, and a retaining edge part e that bends from the side half-edge part d and enters the locking hole 3 to prevent it from coming off. This second attachment part S2 is fixed to the support P using the locking hole 3.

[0046] 1 and 8 to 12 show a state in which the belt hook 1B is attached to the central support P facing the article storage shelf 2, and the perspective views of FIGS. 8 and 9 show the support P as viewed from above and behind.

[0047] The belt hook 1B is removed by removing the clamping side c of the first attachment part S1 from the support P in the state shown in FIG. 9(a), which is then in the released state shown in FIG. 9(b). When the mounting part S1 is rotated away from the support P, it assumes the state shown in Figure 9(c), and from that state, by twisting it or changing the angle relative to the support P, the anti-slip edge part e of the second mounting part S2 is removed from the locking hole 3 as shown in Figure 9(d).

[0048] The procedure for attaching the belt hook 1B is the reverse of the removal procedure. First, insert the retaining edge e of the second attachment part S2 into the locking hole 3 in the side wall Pa of the support P (Fig. 9(d)}. Then, rotate the first attachment part S1 so as to press down, bringing the tip of the retaining edge e into contact with the inner surface of the side wall Pa (Figs. 9(c)(b)}. Then, fit the first attachment part S1 to the support P by bringing the back horizontal edge f of the first attachment part S1 close to the back wall Pb of the support P and bringing the side horizontal edge b into contact with the side wall Pa. During this fitting, the clamping edge c elastically deforms and comes into contact with the back wall Pb of the support P, so that the clamping edge c, together with the back horizontal edge f, clamps the support P (Fig. 9(a)).

[0049] As with the belt hook 1A of the first embodiment, the belt hook 1B of the second embodiment may also be manufactured in two types with symmetrical shapes, and the first belt hooks 1 at both the left and right ends of the belt B may both have the first attachment portion S1 located on the lower (or upper) side.

[0050] Furthermore, in the belt hook 1A of the first embodiment, the front horizontal edge portion a bent from one end of the belt hook portion Sm crosses the front wall Pc of the support P, whereas in the belt hook 1B of the second embodiment, the back horizontal edge portion f bent from the side horizontal edge portion b crosses the back wall Pb of the support P. Therefore, the front horizontal edge portion a and the back horizontal edge portion f do not interfere with each other, and the belt hook 1A and the belt hook 1B can be attached side by side at the same height as shown in the lower diagram of the intermediate support P in Figure 1.

[0051] A belt hook 1C of the third embodiment and an article fall prevention device 10 using the same are shown in FIGS.

[0052] The belt hook 1C has a belt hook portion Sm that is arranged along the side edge of the front wall Pc of the support P and on which the belt end Ba is hooked so that its vertical position can be changed, a first attachment portion S1 that is provided at one end of the belt hook portion Sm and is attached to the support P using the locking hole 3, and a second attachment portion S2 that is provided at the other end of the belt hook portion Sm and is attached to the support P using the locking hole 3, and is formed in a vertically symmetrical shape.

[0053] The belt hook Sm has a length at least twice the width of the belt B to be hooked, and both the first mounting part S1 and the second mounting part S2 are fixed to the support P by using the locking holes 3.

[0054] The belt hanging portion Sm is formed from a rod material, and the first mounting portion S1 and the second mounting portion S2 are formed by bending both ends of the rod material from both ends of the belt hanging portion Sm along the side edge of the support P in a direction along the side wall Pa, and an attachment plate K that is placed against the side wall Pa is fixed to the end, and this attachment plate K is attached with a fastener N that passes through the engagement hole 3.

[0055] The belt hook 1C of the third embodiment has a vertically symmetrical shape, so one type of belt hook 1C can be arranged in a left-right inverted position and connected to both the left and right ends of the belt B. However, the belt hook 1C can also be formed into two types with left-right symmetrical shapes.

[0056] Furthermore, in the belt hook 1A of the first embodiment, the front horizontal edge portion a bent from one end of the belt hook portion Sm crosses the front wall Pc of the support P, whereas in the belt hook 1C of the third embodiment, the mounting plate K is abutted against the side wall Pa, so that the front horizontal edge portion a and the mounting plate K do not interfere with each other, and the belt hook 1A and the belt hook 1C can be mounted side by side at the same height as shown in the upper diagram of the intermediate support P in Figure 1.

[0057] Figures 18 to 20 show how to use the belt hook 1 for two belts. The belt hook 1 is the belt hook 1A of the first embodiment, but the same can be applied to the belt hooks 1B and 1C.

[0058] The two belts B have their belt ends Ba sewn into a cylindrical shape and fitted directly into the belt hooking portion Sm of the belt hooking hardware 1A, but a hooking hardware F may also be attached to the belt end Ba as shown in FIG.

[0059] The item storage shelf 2 has three support pillars P erected at intervals on each of the front and rear sides, and shelf members T on which items W are placed are supported in five tiers, one above the other, between two support pillars P on each of the front and rear sides, forming a two-tier five-tier shelf structure, and two sets of item fall prevention devices 10 are attached to the front of this item storage shelf 2 corresponding to the shelf members T on each tier.

[0060] On the shelf members T of the L and R series, from the top shelf T1 to the third shelf T3, two belts B are attached to each item W on the shelf member T to prevent it from falling. This is because items with a high center of gravity can climb over the belt and fall due to the shaking of an earthquake, so it is better to have two belts B to prevent this. Also, thin items such as books can fall from under the belt after tipping over on the shelf, so to prevent this, it is better to have belts B facing the high and low positions of the thin items.

[0061] A belt hook 1A is attached to the left support pillar P of the L and R trains with the first attachment part S1 facing downwards, and a belt hook 1A is attached to the right support pillar P of each train with the first attachment part S1 facing upwards, and one or two belts B are hung across the belt attachment parts Sm of both belt hooks 1A to form an article fall prevention device 10.

[0062] In the uppermost article fall prevention device 10-1, the belt hooking portion Sm of the belt hook 1A is positioned above and away from the uppermost shelf member T1, and one narrow belt Bu is hooked over the upper part of the article so as to face each other.

[0063] In the second to fourth tier article fall prevention devices 10-2, 10-3, and 10-4, the belt hooking portion Sm of the belt hook fitting 1A is positioned so that its vertical midpoint faces the shelf members T1 to T3 of the first to third tiers, respectively, and hooks a wide belt Bd facing the lower side of the article W and a narrow belt Bu facing the upper side of the lower article.

[0064] In the article fall prevention devices 10-2 and 10-3, a wide belt Bd and a narrow belt Bu are hung on one belt hanging portion Sm. For example, the wide belt Bd is 50 mm wide, and the narrow belt Bu is 25 mm wide. The belt B may have other widths.

[0065] In the L series, the wide belt Bd faces the lower side and the narrow belt Bu faces the upper side relative to the items W placed on each of the shelf members T1 to T3, and in the R series, the wide belt Bd can be lowered to a position facing the shelf members T1 to T3 respectively relative to the items W placed on each of the shelf members T1 to T3, and the narrow belt Bu can be moved to an upper position where it does not face the items W.

[0066] In the R-series, the article fall prevention device 10-1 can move the narrow belt Bu to an upper position where it does not face the article W, the article fall prevention device 10-2 moves the narrow belt Bu to a position where it overlaps with the shelf member T1 so that it does not face the article W, and the article fall prevention device 10-3 moves the wide belt Bd below the top surface of the shelf member T2 so that it does not face the article W.

[0067] The present invention is not limited to the above-described embodiment, and the shapes, configurations and combinations of the members may be varied. You can also change the combination, etc.

[0068] For example, the belt hook 1 is formed from a cylindrical bar, but it can also be formed from a square bar. The belt hook 1 may also be a plate with a groove formed therein for sliding the belt B.

[0069] It is best for belt B to be stretched horizontally at the position α facing the stored item, but an inclination is also acceptable. Changing belt B from the position α facing the stored item to the position β not facing the stored item is also done by alternately moving both ends of belt B on belt loop Sm.
