[0004] [Patent Document 1] Utility Model Registration No. 3222425 Summary of the Invention [Problem to be solved by the invention]

[0005] In the above-mentioned conventional technology, when an item moves forward so as to fall off the storage shelf, the item comes into contact with the belt portion and is deformed by expanding forward, and at this time the stretchable portion is elastically stretched, thereby braking the forward movement of the item and ultimately preventing the item from falling.

[0006] Although the above-mentioned prior art can prevent the article from falling, the forward movement of the article is only controlled by the elastic resistance of the expansion and contraction section, so it is difficult to absorb a large impact, and the forward movement of the article may be large.

[0007] To provide a fall prevention belt in which an elastic belt is connected between both ends of a belt body to form a loop shape, and an article abuts against the folded double part of the belt body, so that the outward movement of the article can be braked by the frictional resistance of the double part of the belt body.

[0008] The object of the present invention is to provide an article fall prevention device in which an elastic belt is connected between both ends of a belt body to form a loop shape, which is then hung between two belt hooks so that an article abuts against the folded double part of the belt body, and the outward movement of the article is braked by the frictional resistance of the double part of the belt body. [Means for solving the problem]

[0009] The specific means for solving the problem in the fall prevention belt of the present invention is a fall prevention belt that is hung between two belt hooks 3, and is characterized by having a belt main body 5 that has back portions 5b on both sides that are wrapped around the belt hooks 3 and folded back on both sides of an outer surface portion 5f that forms the belt outer surface f, and an elastic belt 6 that connects the back portions 5b on both sides, and the elastic belt 6 is connected m to the outer surface portion 5f.

[0010] The specific means for solving the problem in the article fall prevention device of the present invention is an article fall prevention device having a belt hook 3 attached to two shelf supports P and a belt 4 hung between the two belt hooks 3 on the outside of an article W on a shelf member T, The belt 4 is formed in a loop shape and includes a belt body 5 having back portions 5b on both sides that are wound around the belt hooks 3 and folded back on both sides of an outer surface portion 5f that forms the belt outer surface f, and an elastic belt 6 that connects the back portions 5b on both sides. The elastic belt 6 is connected to the outer surface portion 5f. The back surface portions 5b on both sides are characterized in that they abut against the inner periphery of the loop of the outer surface portion 5f. [Effects of the Invention]

[0011] According to the present invention, the outward movement of the article can be stopped by the frictional resistance of the double portion of the belt body, and even large impacts from the article can be absorbed. [Brief explanation of the drawings]

[0013] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0014] In FIG. 1, the item storage shelf 2 has two or more shelf supports P erected on the left and right sides on the front (front) side, and two or more shelf supports P erected on the left and right sides on the rear side, and a shelf member T on which an item W is placed is supported between the two shelf supports P on the front side and the two shelf supports P on the rear side and fixed to the shelf supports P.

[0015] A row of shelves is formed between two shelf supports P, and Fig. 1 shows the first row of shelves and part of the second row of shelves. The front and rear sides of the item storage shelf 2 are in a front-to-back positional relationship, and if items W can be taken in and out from either the front or the rear, the distinction between the front and rear sides disappears.

[0016] The article storage shelf 2 in FIG. 1 has article fall prevention devices 10 (10A, 10B, 10C) of the first embodiment attached to the outer surfaces of the second to fourth shelves from the bottom.

[0017] As shown in Figures 1, 5, 7, and 8, the shelf support P has a roughly U-shaped cross section and has a front wall Pc and left and right side walls Pa, and the left and right side walls Pa have a number of locking holes Pb arranged in a vertical row to lock other components and to reduce weight.

[0018] The article fall prevention device 10 (10A, 10B, 10C) has belt hooks 3 (3A, 3B, 3C) attached to the left and right shelf supports P, and a belt 4 (fall prevention belt) hung between the left and right belt hooks 3 outside the article W on the shelf member T.

[0019] The first type article fall prevention device 10A is disposed in correspondence with the second storage shelf 2 in Fig. 1 and has left and right belt hooks 3A and a belt 4. The second type article fall prevention device 10B is disposed in correspondence with the third storage shelf 2 in Fig. 1 and has left and right belt hooks 3B and a belt 4. The third type article fall prevention device 10C is disposed in correspondence with the fourth (top) storage shelf 2 in Fig. 1 and has left and right belt hooks 3C and a belt 4.

[0020] The belt 4 is common to the first to third types of article fall prevention devices 10 (10A, 10B, 10C), and as shown in Figure 2, the belt body 5 is formed by an outer surface portion 5f that forms the belt outer surface f, and left and right back portions 5b that are wrapped around the belt hooks 3 on both left and right sides of the outer surface portion 5f and folded back, and both ends of an elastic belt 6 are connected to the ends of the left and right back portions 5b by sewing h or the like, forming a loop shape.

[0021] The belt body 5 of the belt 4 shown in Figure 2 may be a resin belt, but a woven fabric belt or leather belt with high friction resistance is preferable, and the outer surface 5f of the belt body 5 and the surfaces on the inner periphery of the loops of the left and right back portions 5b have higher friction resistance than the surface of the elastic belt 6.

[0022] The elastic belt 6 is preferably a belt made of synthetic rubber or elastic resin. The approximate center of the elastic belt 6 in the longitudinal direction and the approximate center of the outer surface portion 5f in the longitudinal direction are connected by sewing, or by thick thread, braided cord, or the like.

[0023] The length of the elastic belt 6 is preferably 20 to 60% of the distance between the left and right belt hooks 3 .

[0024] The inner peripheral surfaces of the loops of the left and right rear portions 5b face the inner peripheral surfaces of the loops of the outer surface portion 5f, and when the article W moves forward, they are pushed by the article W and can abut against the inner peripheral surfaces of the loops of the outer surface portion 5f.

[0025] Figure 5(A) shows the normal state in which the belt 4 is wound around the left and right belt hooks 3A, and the elastic belt 6 is connected to the center of the outer surface portion 5f, but the inner surfaces of the loops on the left and right back portions 5b face the inner surfaces of the loops on the outer surface portion 5f via a gap.

[0026] FIG. 5(B) shows a state change from the normal state to a state where the article W moves forward due to an earthquake or the like, and the movement of the article W is stopped by the belt 4, thereby exerting a fall prevention function.

[0027] When the fall prevention function is activated, an article W moving forward collides with the back surface of the left and right rear portions 5b, and is pushed by the article W, causing the inner surfaces of the loops of the left and right rear portions 5b to abut against the inner surfaces of the loops of the outer surface portion 5f, and pushing both of them forward.

[0028] This pushing action results in pulling R toward the center at both left and right ends of the outer surface portion 5f, and pulling S toward the left and right outward at the left and right ends of the left and right back portions 5b.

[0029] Therefore, at the contact portions between the inner peripheral surfaces of the loops of the left and right back portions 5b and the outer peripheral surfaces of the loops of the outer surface portions 5f, frictional resistance (rubbing resistance) occurs due to the opposite directions of the tensions R and S, which adds to the frictional resistance caused by the pressure of the article W. At this time, frictional resistance also occurs between the back surfaces (outer peripheral surfaces of the loops) of the left and right back portions 5b and the article W.

[0030] These added frictional resistances limit the movement of the pulling force S of the left and right back portions 5b, which brakes the forward movement of the article W. This braking suppresses the stretching of the elastic belt 6 between the left and right back portions 5b, and even if the forward movement of the article W is a large impact, excessive stretching of the elastic belt 6 is suppressed, preventing damage.

[0031] 3 shows a modified example of the belt 4, in which the approximate center in the longitudinal direction of the elastic belt 6 and the approximate center in the longitudinal direction of the outer surface portion 5f are connected via a clamp 13. The clamp 13 clamps the elastic belt 6 and the outer surface portion 5f with three or four claws 13a.

[0032] When the clamping device 13 of the belt 4 is fitted into the approximate center of the left and right belt hooks 3 and the approximate center of the longitudinal direction of the elastic belt 6 to clamp the belt body 5, the dimensions of the left and right back portions 5b facing the outer surface portion 5f become approximately equal on the left and right, and the function of cushioning the collision of the item W can be exerted approximately equally on the left and right.

[0033] In the belt 4 shown in Figures 2 and 3, the back surfaces of the left and right ends of the elastic belt 6 are sewn to the inner peripheral surfaces of the loops of the left and right back portions 5b, but the inner peripheral surfaces of the loops of the left and right ends of the elastic belt 6 may also be sewn to the back surfaces of the left and right back portions 5b.

[0034] In Figures 1 and 4, the left and right belt hooks 3A of the first type article fall prevention device 10A arranged corresponding to the second storage shelf 2 have vertically elongated holes 15 to form belt winding portions 16 parallel to the holes 15, and L-shaped claw-shaped upper and lower engagement attachment portions 3a on the opposite side of the belt winding portion 16.

[0035] The belt 4 is passed through the hole 15 of the belt hook 3A in advance and hung on the belt winding portion 16, and the upper and lower engaging attachment portions 3a of one of the left and right belt hooks 3A are engaged with the locking hole Pb formed in the side wall Pa of one of the shelf support posts P, and then, while pulling the belt 4, the upper and lower engaging attachment portions 3a of the other left and right belt hook 3A are engaged with the locking hole Pb formed in the side wall Pa of the other shelf support P.

[0036] The belt hook fittings 3A can be easily attached and detached to and from the item storage shelf 2 by simply engaging and detaching the upper and lower engaging attachment parts 3a with the inner side wall Pa of the shelf support column P. In addition, the belt hook fittings 3A can be positioned at the same height on the first and second series of shelves.

[0037] 1, 6 and 7, the left and right belt hook fittings 3B of the second type article fall prevention device 10B arranged corresponding to the third tier storage shelf 2 have an upwardly open vertical groove 17 formed on one side of a plate material 18 that fits along the front wall Pc of the shelf support P, thereby forming a belt winding portion 16 that is parallel to the groove 17, and the other side of the plate material 18 is bent to fit along the outer side wall Pa of the shelf support P, and an L-shaped claw-shaped upper and lower engaging attachment portion 3a is formed on the edge of the bent side (the side opposite to the belt winding portion 16).

[0038] The belt hook fitting 3B is fitted to the front wall Pc and the side wall Pa of the shelf support P so as to hug the latter, and the engaging attachment part 3a is engaged with and disengaged from the outer side wall Pa of the shelf support P while pulling the belt 4, so that the engagement between the locking hole Pb and the engaging attachment part 3a can be reliably achieved.

[0039] Because the groove 17 of the belt hook 3B is open upward, the belt 4 can be hooked on the belt winding portion 16 when the belt hook 3B is attached to the shelf support P, and the engaging attachment portion 3a engages with the outer side wall Pa of the shelf support P, making it easy to attach and detach the article fall prevention device 10B to and from the article storage shelf 2. However, the belt hooks 3B cannot be positioned at the same height on the first and second series of shelves, and must be positioned offset vertically.

[0040] In Figures 1 and 8, the left and right belt hooks 3C of the third type article fall prevention device 10C arranged corresponding to the fourth storage shelf 2 are identical and are attached to the left and right shelf supports P upside down.

[0041] The belt hook fitting 3C has a belt hooking portion Sm that runs along the side edge of the front wall Pc of the shelf support P and hooks the belt 4 in an up-down position that can be changed, an engaging attachment portion 3b that is provided at one end of the belt hooking portion Sm and attached to the shelf support P, and an engaging attachment portion 3a that is provided at the other end of the belt hooking portion Sm and attached to the shelf support P using the locking hole Pb, and the belt hooking portion Sm, engaging attachment portion 3b and engaging attachment portion 3a are formed from a single rod (also called wire).

[0042] The fitting attachment portion 3b 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 shelf 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 shelf support P, and a clamping edge portion c that bends from the side horizontal edge portion b and wraps around behind the shelf support P and clamps the shelf support P together with the front horizontal edge portion a.

[0043] The engaging attachment portion 3a has a side half-edge portion d that bends from the other end of the belt hook portion Sm and crosses the side wall Pa of the shelf support P to the locking hole Pb, and a retaining edge portion e that bends from this side half-edge portion d and enters the locking hole Pb to prevent it from falling out.

[0044] The belt hook fitting 3C is detachably engaged from the outer surface side of the shelf support P with the engaging attachment portion 3a into the locking hole Pb formed in the inner side wall Pa of the shelf support P, making it extremely easy to wrap the belt 4 around the belt hook portion Sm and to attach and detach the item fall prevention device 10C to and from the item storage shelf 2.

[0045] Furthermore, in the belt hook 3C, the belt 4 can be changed in vertical position within the range of the vertical length of the belt hook portion Sm, and in the first series of shelves in Figure 1, the position can be changed from a position α facing the stored items to a position β not facing the stored items, which allows items to be put in and taken out.

[0046] In addition, in the storage shelf 2 on the fourth level of the second row of shelves in Figure 1, the belt hook portion Sm of the belt hook fitting 3C is positioned so as to extend upward from the position where it overlaps with the storage shelf 2, so that the belt 4 faces the storage shelf 2 to form a non-facing position β for stored items, and above that a facing position α for stored items is formed.

[0047] The belt 4 (fall prevention belt) of the article fall prevention device 10 (10A, 10B, 10C) of the first embodiment is attached to the front (front) side of the article storage shelf 2 to brake the forward movement of the article W, but it may also be attached to the rear side of the article storage shelf 2 to brake the outward movement of the article W. Also, since there are article storage shelves 2 in which articles W are loaded and unloaded from both the front and rear sides, it is preferable in that case to also attach the article fall prevention device 10 to both the front and rear sides of the article storage shelf 2.

[0048] 9 and 10 show an article fall prevention device 10 (10E) of a second embodiment in which fall prevention belts 4E are attached from the left and right side surfaces of the article storage shelf 2 to the rear surface.

[0049] The article fall prevention device 10 (10E) has belt hooks 3 (3E) attached to the left and right shelf supports P on the front, a belt 4 (fall prevention belt 4E) hung between the left and right belt hooks 3 on the left and right sides and rear of the article W on the shelf member T, and mid-belt hooks 31 attached to the two left and right shelf supports P on the rear and wrap around the middle part of the belt 4 (4E).

[0050] The belt 4 (4E) is hung between two belt hooks 3, passing from one of the belt hooks 3E on the left and right of the outer surface (front surface) through the outer surfaces of the two shelf supports P on the left and right of the rear surface to the other belt hook 3 on the left and right of the outer surface (front surface).

[0051] The belt 4 (4E) is formed in a loop shape and has a belt body 5 having back portions 5b on both sides that are wrapped around the belt hooks 3 and folded back on both sides of an outer surface portion 5f that forms the belt outer surface f, and an elastic belt 6 that connects the back portions 5b on both sides.

[0052] Both ends of the elastic belt 6 are folded over and sewn together (h) so as to fit onto the ends of the back portion 5b on both sides, and the longitudinal center of the elastic belt 6 is connected to the outer surface portion 5f by sewing (m).

[0053] As a result, the folded portion of the belt 4 (4E) from the outer surface portion 5f to the back surface portion 5b fits into the belt hook 3, and the intermediate portion where the outer surface portion 5f and the back surface portion 5b overlap is hooked onto the intermediate belt hook 31, and the entire length from the back surface portions 5b on both sides to the elastic belt 6 is abutted against the inner circumference of the loop of the outer surface portion 5f.

[0054] 11 and 12 show an article fall prevention device 10 (10F) of the third embodiment that is attached to the left and right side surfaces of the article storage shelf 2.

[0055] The article fall prevention device 10 (10F) has two belt hooks 3 (3F) attached to one of the front and rear shelf support posts P on the side, and a belt 4 (fall prevention belt 4F) stretched between the two belt hooks 3, passing from one belt hook 3 along the outer surface of the other front and rear shelf support post P on the side to the other belt hook 3.

[0056] The belt 4 (4F) is formed in a loop shape and has a belt body 5 having back portions 5b on both sides that are wound around two belt hooks 3 and folded back on both sides of an outer surface portion 5f that forms the belt outer surface f, and an elastic belt 6 that connects the back portions 5b on both sides.

[0057] Both ends of the elastic belt 6 are folded over and sewn together (h) so as to fit onto the ends of the back portion 5b on both sides, and the longitudinal center of the elastic belt 6 is connected to the outer surface portion 5f by sewing (m).

[0058] The elastic belt 6 is connected to the outer surface portion 5f by stitching and abuts against the outer surface of the other shelf support P on the front and rear sides of the side, and the back portions 5b on both sides abut against the inner circumference of the loop of the outer surface portion 5f.

[0059] In the third embodiment of the article fall prevention device 10 (10F), the two belt hooks 3 can be engaged with either the front or rear shelf support P on the left or right side, and the longitudinal center of the belt 4 (4F) is wrapped around the other shelf support P, thereby restricting the lateral movement of the article W.

[0060] If the belt 4 (4F) is attached to the middle shelf support P of the multiple article storage shelf 2, it will be possible to restrict the lateral movement of the articles W on the left and right double shelves.

[0061] The material of the belt 4 (4E, 4F) of the second and third embodiments is substantially the same as that of the belt 4 of the first embodiment, and the outer surface 5f of the belt main body 5 and the inner surface of the loop of the back surface portions 5b on both sides have a higher friction resistance than the elastic belt 6, thereby increasing the rubbing resistance between the outer surface portions 5f and the back surface portions 5b.

[0062] In addition, the belt hooks 3 (3E, 3F) and intermediate belt hooks 31 of the second and third embodiments are formed with a central straight section made of rod material on which the belt 4 is hung and engaging attachment sections 3a that bend from both ends and engage with the locking holes in the shelf support P, and the belt hooks 3A, 3B, 3C shown in the first embodiment may also be applied.

[0063] In the embodiment of the fall prevention belt described above, the fall prevention belt is hung between two belt hooks 3, and is formed in a loop shape with a belt main body 5 having back portions 5b on both sides that are wrapped around the belt hooks 3 and folded back on both sides of an outer surface portion 5f that forms the belt outer surface f, and an elastic belt 6 that connects the back portions 5b on both sides, and the elastic belt 6 is connected to the outer surface portion 5f.

[0064] With this configuration, the outward movement of the article W can be stopped by the frictional resistance of the double portion of the belt body 5 (doubled by the outer surface portion 5f and the back surface portion 5b), and large impacts from the article W can also be absorbed.

[0065] In this embodiment of the fall prevention belt, the outer surface 5f of the belt body 5 and the surfaces of the inner circumferential sides of the loops of the back surface portions 5b on both sides have a larger friction resistance than the elastic belt 6.

[0066] This configuration can increase the friction resistance between the outer surface portion 5f and the back surface portion 5b.

[0067] In the embodiment of the article fall prevention device described above, the article fall prevention device has belt hooks 3 attached to two shelf posts P and a belt 4 hung between the two belt hooks 3 outside the article W on the shelf member T, and the belt 4 is formed in a loop shape having a belt body 5 that is wrapped around the belt hooks 3 on both sides of an outer surface portion 5f that forms the belt outer surface f and has back portions 5b on both sides that are folded back, and an elastic belt 6 that connects the back portions 5b on both sides, and the elastic belt 6 is connected to the outer surface portion 5f, and the back portions 5b on both sides abut against the inner side of the loop of the outer surface portion 5f.

[0068] With this configuration, the outward movement of the article W can be stopped by the frictional resistance of the double portion of the belt body 5 (doubled by the outer surface portion 5f and the back surface portion 5b), and large impacts from the article W can also be absorbed.

[0069] In addition, in an embodiment of the article fall prevention device, the article fall prevention device has belt hooks 3 attached to the left and right shelf posts P and a belt 4 hung between the left and right belt hooks 3 in front of an article W on a shelf member T, and the belt 4 is formed in a loop shape having a belt main body 5 having left and right back portions 5b that are wrapped around the belt hooks 3 on both the left and right sides of an outer surface portion 5f that forms the belt outer surface f and folded back, and an elastic belt 6 that connects the left and right back portions 5b, and the elastic belt 6 is connected to the outer surface portion 5f m, so that when the article W moves forward, the left and right back portions 5b are pushed by the article W and can abut against the inner side of the loop of the outer surface portion 5f.

[0070] With this configuration, the forward movement of the article W can be braked by the frictional resistance of the double portion of the belt body 5 (doubled by the outer surface portion 5f and the back surface portion 5b), and large impacts from the article W can also be absorbed.

[0071] In addition, in an embodiment of the article fall prevention device, the device has belt hooks 3 attached to two shelf supports P on the left and right sides of the front, and a belt 4 hung between the two belt hooks 3, running from one of the belt hooks 3 on the left and right sides of the front, passing around the outside of two shelf supports P on the left and right sides of the rear, to the other belt hook 3 on the left and right sides of the front, the belt 4 is formed in a loop shape having a belt body 5 that is wound around the belt hooks 3 on both sides of an outer surface 5f that forms the belt outer surface f and has back surfaces 5b on both sides that are folded back, and an elastic belt 6 that connects the back surfaces 5b on both sides, the elastic belt 6 is connected to the outer surface 5f m, and the back surfaces 5b on both sides are abutted against the inner periphery of the loop of the outer surface 5f, and intermediate belt hooks 31 that wrap around the intermediate portion of the belt 4 are attached to the two shelf supports P on the left and right sides of the rear.

[0072] With this configuration, the lateral and rearward movement of the article W can be braked by the frictional resistance of the double portion of the belt body 5 (doubled by the outer surface portion 5f and the back surface portion 5b), and even large impacts from the article W can be absorbed.

[0073] In addition, in an embodiment of the article fall prevention device, the article fall prevention device has two belt hooks 3 attached to one of the shelf support posts P on the front or rear of the side, and a belt 4 hung between the two belt hooks 3, running from one belt hook 3 along the outer surface of the other shelf support post P on the front or rear of the side to the other belt hook 3, wherein the belt 4 is formed in a loop shape having a belt body 5 that is wrapped around the two belt hooks 3 on both sides of an outer surface portion 5f that forms the belt outer surface f and has back portions 5b on both sides that are folded back, and an elastic belt 6 that connects the back portions 5b on both sides, and the elastic belt 6 is connected to the outer surface portion 5f and abuts against the outer surface of the other shelf support post P on the front or rear of the side, and the back portions 5b on both sides abut against the inner periphery of the loop of the outer surface portion 5f.

[0074] With this configuration, the lateral movement of the article W can be braked by the frictional resistance of the double portion of the belt body 5 (doubled by the outer surface portion 5f and the back surface portion 5b), and large impacts from the article W can also be absorbed.

[0075] Furthermore, in this embodiment of the article fall prevention device, the elastic belt 6 has a length that is 20 to 60% of the distance between the left and right belt hooks 3 .

[0076] This configuration allows the double portion of the belt body 5 to be placed facing the outer surface of the article W.

[0077] In this embodiment of the article fall prevention device, the outer surface 5f of the belt main body 5 and the surfaces of the inner circumferential sides of the loops of the back surface portions 5b on both sides have a larger friction resistance than the elastic belt 6.

[0078] This configuration can increase the friction resistance between the outer surface portion 5f and the back surface portion 5b.

[0079] In this embodiment of the article fall prevention device, the belt hook 3 has an engaging attachment portion 3a that engages with an engaging hole Pb formed in the side wall Pa of the shelf support P in a freely releasable manner.

[0080] This configuration allows the article fall prevention device 10 to be easily attached to and detached from the storage shelf 2.

[0081] The present invention is not limited to the above-described embodiment, and the shapes, configurations, and combinations of the components can be changed.

[0082] For example, the belt body 5 may be provided with a belt length adjuster on the outer surface 5f thereof. [Explanation of symbols]
