  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 schematically shows a belt fixture according to an embodiment of the present invention, where (a) is a plan view and (b) is a front view.

  The belt fixture 1 is a rectangular plate-like member that fixes the fall-preventing belt to an iron-made support column of an article shelf. One end of the belt fixture 1 is provided with a connection part 2 to which a fall prevention belt is connected, and the other end opposite to the connection part 2 is provided with a fall prevention belt connected to the connection part 2 with a column. A retaining groove 3 is formed to be latched in a state of being wound once. In this embodiment, the connection part 2 is formed by the slit hole provided in parallel with the long side of the rectangle. The retaining groove 3 is formed by providing a slit hole similar to the connecting portion 2 in parallel with the connecting portion 2 and opening the upper portion thereof.

  On the back surface of the belt fixture 1, a magnetic body 4 is provided for adsorbing and fixing the belt fixture 1 to a support column. The magnetic body 4 is formed in a rectangular plate shape, and is attached between the connection portion 2 and the latching groove 3 by a mounting metal fitting 6 and an eyelet rod 7.

  The magnetic body 4 preferably has a magnetic flux density of 0.3 to 1.5 T in consideration of the stability during adsorption and the influence of the magnetic force on the stored article. Moreover, as a raw material of the magnetic body 4, a neodymium magnet and a samarium cobalt magnet are suitable.

  2A and 2B schematically show a fall prevention device using the belt fixture 1, wherein FIG. 2A is a plan view and FIG. 2B is a front view.

  The fall prevention tool 10 is spanned between iron or the like columns of the article shelf to prevent the article from falling on the shelf board, and is mainly composed of the belt fixing tool 1, the belt 11, and the connecting portion 12. ing.

  The belt 11 is spanned between a pair of left and right columns, and holds the stored articles so as not to protrude from the shelf board to prevent dropping. The material of the belt 11 may be any material that can withstand the load of the stored article, and for example, polyester, polypropylene, nylon, and the like are suitable. One end of the belt 11 is connected to the belt fixture 1, and the left and right belt fixtures 1 are formed so as to be plane-symmetric with each other.

  FIG. 3 shows a state of the connecting portion 2 to which the belt 11 is connected.

  The belt 11 is connected to the belt fixture 1 by folding back the tip inserted into the slit hole of the connecting portion 2 and sewing it to the body portion of the belt 11. Here, the magnetic body 4 protrudes from the surface of the belt fixture 1 so as to be substantially the same height as the contact surface of the connection portion 2 with the support of the belt 11, and the belt 11 connected to the connection portion 2. The thickness of the material does not become an obstacle during adsorption. That is, in a state where the belt fixture 1 is attracted to the support surface S, the thickness d1 of the attachment portion of the magnetic body 4 is substantially equal to the thickness d2 of the folded portion of the belt 11 connected to the connection portion 2. The height of the contact surface 5 of the magnetic body 4 is set.

  The other ends of the left and right belts 11 are connected to cam buckles 13 and hooks 14, respectively. The cam buckle 13 and the hook 14 constitute a connecting portion 12 as a pair, and the hook connecting end 15 of the hook 14 can be connected to the belt connecting portion 15 of the cam buckle 13 by connecting them. it can. The cam buckle 13 is provided with a release lever 17 loaded with a torsion spring, and can be fixed with the belt 11 sandwiched between the belt connecting portion 15 a and the release lever 17. If the release lever 17 is pushed down, the fixing position of the belt 11 can be changed, so that the overall length of the fall prevention device 10 can be adjusted. Further, a protective sleeve 18 is provided so as to cover a part of the belt 11 in order to accommodate the remaining tip of the belt 11.

  The connecting portion 12 can be configured by only the cam buckle 13 by eliminating the hook 14 and directly connecting the tip of the belt 11 to the belt connecting portion 15 of the cam buckle 13. This is preferable because the belts 11 can be easily connected to each other. Instead of these, other types of buckles such as a ratchet buckle, an over-center buckle, a steel wire buckle such as a French ring or a D ring may be used.

  Next, the usage method of the fall prevention tool 10 comprised in this way is demonstrated, referring drawings.

  FIG. 4 is a diagram illustrating a state where the fall prevention device 10 is spanned over the article shelf A.

  In order to hang the fall prevention tool 10 to the article shelf A, first, the belt 11 is attached to the left and right columns of the article shelf A by the belt fixing tool 1. Next, the hook 14 is engaged with the cam buckle 13 and the tip of the belt 11 connected to the cam buckle 13 is pulled to tighten the entire fall prevention device 10 to remove slack.

  FIG. 5 shows the state of the attachment portion of the fall prevention device 10 attached to the support column of the article shelf A in a horizontal section. Hereinafter, in any cross-sectional view, the lower side is the front of the article shelf A.

  In order to attach the belt 11 to the right column 20 of the article shelf A, first, the end provided with the belt fixing tool 1 is wound around the column 20 from the outside of the article shelf A, and the inner column surface 21 is covered by the magnetic body 4. It is adsorbed to the front end of the. Next, the belt 11 extending from the belt fixture 1 is hooked so as to be sandwiched between the hooking grooves 3 from above, thereby forming a loop at the tip of the belt 11 and tightening it. At this time, in order to make the belt 11 as close as possible to the support column 20, it is desirable that portions other than the retaining groove 3 of the belt fixture 1 do not protrude from the support surface 21. Similarly, the belt 11 can be attached to the left column of the article shelf A.

  FIGS. 6-9 shows the other attachment state of the fall prevention tool 10 similarly to FIG.

  In the above attachment method, the end of the belt 11 is fixed so that the length of the belt 11 wound around the support column 20 is the shortest. However, as shown in FIG. The belt 11 may be attached to the right end of the column surface 22 so that a part of the belt 11 wound around the column 20 overlaps. By doing in this way, when the fall prevention tool 10 is tightened, the belt fixing tool 1 is pressed down from the top by the belt 11 latched by the latching groove 3, and the stability of attachment is improved. Moreover, according to this attachment method, as shown in FIG. 7, even if it is the L-shaped support | pillar 30 which does not have a suitable support | pillar surface inside, the edge part of the belt 11 can be fixed similarly.

  Further, as shown in FIGS. 8 and 9, the end portion of the belt 11 is wound around the support column 30 and the support column 20 from the inside of the article shelf, and the belt fixing tool 1 is adsorbed to the left end of the support column surface 31 and the support column surface 22. It can also be fixed. However, with this attachment method, when the belt fixing tool 1 is displaced in the pulling direction due to excessive tension applied to the belt 11, a sufficient space for preventing the belt fixing tool 1 from falling off as a margin of displacement cannot be obtained. Therefore, when this attachment method is employed, care must be taken not to apply excessive tension to the belt 11.

  The fall prevention tool 10 is held by the magnetic body 4 provided on the belt fixing tool 1 such that both ends are attracted to the support surface and the end of the belt 11 is wound around the support by the retaining groove 3. Yes. That is, the magnetic force of the magnetic body 4 and the frictional force that the belt 11 receives from the surface of the support 11 act on the attachment portion X of the fall prevention device 10 to the support. Hateful.

  Furthermore, since the contact surface 5 of the belt fixture 1 protrudes at substantially the same height as the contact surface of the belt 11 connected to the connecting portion 2, when the belt fixture 1 is adsorbed to the support column. The belt 11 does not lift from the support surface at the connection portion 2. Accordingly, the belt 11 can be brought into close contact with the column to the end, the frictional force between the column 11 and the column surface is increased, and the attachment position of the belt 11 to the column is more difficult to shift downward.

  On the other hand, the temporary release of the fall prevention tool 10 is performed by releasing the engagement between the cam buckle 13 and the hook 14 after the belt 11 is loosened by pressing the release lever 17 of the cam buckle 13. When the engagement between the cam buckle 13 and the hook 14 is disengaged, the left and right belts 11 hang down on the columns attached thereto due to these weights. As described above, since the belt 11 is held in a state of being wound around the support column, when the one end of the belt 11 is pulled downward by the weight of the cam buckle 13 or the hook 14, the attachment portion X is tightened and strong frictional force is applied. Works. As a result, even if the fall prevention device 10 is temporarily released by the connecting portion 12, the attachment portion X of the belt 11 with the left and right support columns does not shift downward and keeps the attachment position. That is, when the fall prevention device 10 is re-hanged, it is not necessary to adjust the heights at both ends. The hook 14 is re-hanged on the cam buckle 13 and then the tip of the belt 11 connected to the cam buckle 13 is pulled. Just tighten it.

  In this way, the fall prevention device 10 can be easily attached simply by winding the end of the belt 11 around a support made of iron or the like of the article shelf and latching it on the retaining groove 3. The article can be easily put in and out by releasing the engagement. Further, even if the coupling portion 12 is disengaged, the attachment position to the support column does not shift downward, so that the re-passing can be performed quickly. Furthermore, when removing the fall prevention tool 10 from a support | pillar, it is only necessary to lift the belt 11 latched by the latching groove 3 upwards, and to remove. It is also easy to change the height of the joint by loosening the belt 11 that is latched in the latch groove 3.

  That is, according to the belt fixing tool and the fall prevention tool according to the present embodiment, the belt can be easily detached from the support column made of iron or the like without providing a special structure on the support column side. The fall prevention tool which can make it easy to carry over again is implement | achieved.

  The belt fixing device and the fall prevention device according to the present invention have been described based on the embodiments. However, the present invention is not limited to this, and the object of the present invention can be achieved and departs from the gist of the invention. Various design changes can be made within the range not to be included, and these are all included in the scope of the present invention.

  For example, in this embodiment, a part of the upper end of the belt fixing tool is opened to form the retaining groove, but as shown in FIG. 10, the side surface of the belt fixing tool is opened to form the retaining groove. Also good.

  In the present embodiment, only one magnetic body is provided on one side of the belt fixture, but the magnetic body can be dispersed and arranged in a plurality of locations in order to increase the attractive force. If magnetic bodies are provided on both sides of the belt fixture, there is no need to distinguish between the front and back of the belt fixture.

  Furthermore, it is also possible to form the belt fixture itself with a magnetic material so that the entire surface of the belt fixture is attracted to the support column. As a result, the contact area between the belt fixture and the column surface is increased, the stability is increased, and the structure of the belt fixture is simplified and the design is improved.

  Further, a woven fabric, a non-woven fabric, a felt fabric or the like may be attached to the surface of the belt fixture. Thereby, a support | pillar becomes difficult to be damaged at the time of attachment or detachment of a belt fixing tool.

  The belt fixing tool and the fall prevention tool according to the present invention support the corners of the shelf board with a support made of iron or the like, and are suspended between the support pillars in an article shelf in which the space between the support posts is opened to prevent the article from falling. Useful as a fall prevention device, especially for fall prevention devices used in an environment where articles of various sizes are frequently taken in and out and the fall prevention device is repeatedly attached and detached.
