Description

  The present invention relates to a foldable shelf, and more particularly to a foldable shelf that can fold and store a shelf board.

  In general, shelves are often installed in the same place for a long time in order to store articles or display goods. However, shelves used in exhibition halls and event halls are installed only for a short period. Therefore, a folding shelf that does not require a long time for assembly / disassembly work is preferable for such applications.

  Utility Model Registration No. 3153013 (Patent Document 1) describes a foldable shelf that can be folded and stored by lifting a central column.

  However, this foldable shelf is heavy and difficult to carry because it has a central column in addition to the columns at the four corners. If the central column is removed, the weight can be reduced, but a new problem arises that the shelf board folded during storage swings back and forth.

[Preferred embodiment]
Referring to FIG. 1, a folding shelf 1 according to a preferred embodiment of the present invention includes a front support member 20, a rear support member 30, an upper shelf board 11, a lower shelf board 12, and an intermediate shelf board 13, It has string-like braces 40A and 40B.

  The front support member 20 includes two support columns 21 and two connection members 22. Both struts 21 are provided so as to be separated from each other, and are set up at both front corners of the folding shelf 1. The connecting member 22 is bridged between the two columns 21 and is fixed to the columns 21. The rear support member 30 includes two support columns 31 and two connecting members 32. Both struts 31 are provided so as to be spaced apart from each other, and are erected on both corners of the rear surface of the folding shelf 1. The connecting member 32 is spanned between the two columns 31 and is fixed to the columns 31. The front support member 20 and the rear support member 30 are stood facing each other during use.

  The upper shelf board 11 includes a front upper shelf board 11A and a rear upper shelf board 11B. The front upper shelf plate 11A includes an outer end portion 11AA and an inner end portion 11AB. The outer end portion 11AA of the front upper shelf plate 11A is supported by the column 21 so as to be rotatable about the axis A3. That is, the front upper shelf board 11A is connected to the support column 21 by the bolt 21A. The rear upper shelf board 11B includes an outer end portion 11BA and an inner end portion 11BB. The outer end 11BA of the rear upper shelf board 11B is supported by the support 31 so as to be rotatable about the axis A5. That is, the rear upper shelf board 11B is connected to the support column 31 by the bolt 31A.

  The inner end portion 11AB of the front upper shelf board 11A is rotatably connected to the inner end portion 11BB of the rear upper shelf board 11B on the axis A1. That is, the front upper shelf board 11A and the rear upper shelf board 11B are abutted on each inner surface and connected by the bolt 11C. Accordingly, when the center of the upper shelf board 11 (the junction of the front upper shelf board 11A and the rear upper shelf board 11B) is lifted, the front upper shelf board 11A rotates about the axis A3, and the rear upper shelf board 11B rotates about the axis A5. . Thereby, the upper shelf board 11 can be bend | folded by the axis | shaft A1 at a reverse V shape. However, even if the center of the upper shelf 11 is pushed down, the upper shelf 11 cannot be bent into a V shape because the inner surface of the front upper shelf 11A and the inner surface of the rear upper shelf 11B are in contact with each other.

  The lower shelf board 12 is configured in the same manner as the upper shelf board 11. That is, the lower shelf board 12 includes a front lower shelf board 12A and a rear lower shelf board 12B. The front lower shelf board 12A is rotatably supported on the support column 21 by an axis A4 (bolt 21B). The rear lower shelf board 12B is supported by the column 31 so as to be rotatable about an axis A6 (bolt 31B). The front lower shelf 12A and the rear lower shelf 12B are abutted on each inner surface, and are rotatably connected by an axis A2 (bolt 12C).

  The middle shelf board 13 is composed of one shelf board. A plurality of shelf holes 21 </ b> C are formed on the side surfaces of the two columns 21 that face each other. Similarly, a plurality of shelf holes 31 </ b> C are also formed on the side surfaces of the columns 31 facing each other. A shelf stay (not shown) is inserted into the shelf holes 21C and 31C as necessary. One middle shelf board 13 is supported by four shelf stays. In the example shown in FIG. 1, only one middle shelf board 13 is provided, but two or more middle shelf boards 13 may be provided. Moreover, the middle shelf board 13 does not need to be provided. In this case, the foldable shelf 1 can hang a hanger on the pipe 50 and hang clothes on the hanger. The pipe 50 is suspended from the center of the upper shelf board 11.

  The string-like braces 40 </ b> A and 40 </ b> B are made of wire ropes, and are provided so as to intersect two each on the left and right sides of the folding shelf 1. Specifically, the brace 40 </ b> A is bridged between the upper part of the column 21 and the lower part of the column 31. The brace 40 </ b> B is bridged between the upper part of the support column 31 and the lower part of the support column 21. Each end of the brace 40A, 40B is formed in a loop shape and hooked on the bolts 21A, 21B, 31A, 31B. The braces 40A and 40B extend straight without slack during use and have a specific maximum length. The brace 40A, 40B includes an expansion / contraction part 41 (FIG. 8) that shrinks in a coil shape when stored. A wire rope made by Nikko Steel Co., Ltd. (Kishiwada City, Osaka Prefecture) can be used for the braces 40A and 40B having such functions (see Japanese Patent Laid-Open No. 9-19320 and Utility Model Registration No. 3030856). . This wire rope has a property of returning to a predetermined original shape even if it is straightened without slack.

  With reference to FIG. 2, the support | pillar 31 has axial hole 31A-1. A bolt 31A is inserted into the shaft hole 31A-1.

  The connecting member 32 includes an upper surface portion 321, a side surface portion 322, and a bottom surface portion 323, and is formed so as to cover the outer end portion 11BA of the rear upper shelf board 11B. A rotation restricting member 324 is provided at the end of the bottom surface portion 323. The rotation restricting member 324 is provided around the axis A5 so as to come into contact with the rear upper shelf board 11B when the folding shelf 1 is stored. The upper surface portion 321, the side surface portion 322, the bottom surface portion 323, and the rotation restricting member 324 of the connecting member 32 are integrally formed by bending a single metal plate substantially vertically. The connecting member 32 is thus formed in a bag shape.

  The upper surface portion 321 of the connecting member 32 and the upper surface of the column 31 form substantially the same plane. The rotation restricting member 324 is provided so as to be separated from both the columns 31.

  The connecting member 22 has the same configuration as the connecting member 32 described above.

  Referring to FIG. 3, rear upper shelf board 11B has a hollow structure. Specifically, the rear upper shelf plate 11B is formed by bending a single metal plate substantially vertically, and the outer end portion 11BA of the rear upper shelf plate 11B has a substantially U-shaped cross section. The rotation regulating member 324 is provided below and inside the axis A5, and is located inside the rear upper shelf board 11B when the folding shelf 1 is used. The rotation restricting member 324 is provided in a locus 500 through which one end of the rear upper shelf board 11B passes when the rear upper shelf board 11B is rotated around the axis A5.

  When the foldable shelf 1 is used, the upper surface portion 321 of the connecting member 32 and the upper surface of the rear upper shelf plate 11B form substantially the same plane.

  The front upper shelf board 11A, the front lower shelf board 12A, and the rear lower shelf board 12B have substantially the same configuration as the rear upper shelf board 11B described above.

  Next, a method for storing the foldable shelf 1 will be described.

  First, the middle shelf board 13 is removed from the folding shelf 1 shown in FIG. 1, and then the shelf stays are removed from the shelf holes 21C and 31C.

  Next, when the center of the upper shelf board 11 (joint location of the front upper shelf board 11A and the rear upper shelf board 11B) is lifted, as shown in FIG. 4, the front upper shelf board 11A rotates around the axis A3, and the rear upper shelf board is rotated. The plate 11B rotates around the axis A5, and the upper shelf board 11 is folded in half along the axis A1.

  At this time, as shown in FIG. 5, the back surface 11 </ b> B- 1 of the rear upper shelf board 11 </ b> B hits the rotation restricting member 324. Therefore, the rear upper shelf board 11B cannot rotate more than 90 degrees. Since the front upper shelf board 11A and the connecting member 22 have the same configuration as the rear upper shelf board 11B and the connecting member 32, the front upper shelf board 11A cannot rotate more than 90 degrees. As a result, the folded upper shelf board 11 does not move back and forth.

  At this time, the braces 40A and 40B contract. As shown in FIGS. 4 and 6, the braces 40 </ b> A and 40 </ b> B include a stretchable portion 41 that contracts in a coil shape when the folding shelf 1 is stored.

  Finally, when the center of the lower shelf board 12 (the junction of the front lower shelf board 12A and the rear lower shelf board 12B) is lifted, the front lower shelf board 12A rotates around the axis A4 as shown in FIG. The rear lower shelf 12B rotates around the axis A6, and the lower shelf 12 is folded in half on the axis A2. Since the lower shelf board 12 has the same configuration as the upper shelf board 11, the folded lower shelf board 1 does not swing back and forth.

  At this time, the braces 40A and 40B are further contracted as compared with the state shown in FIG. 6, as shown in FIG. Therefore, the braces 40A and 40B are automatically stored without slack.

  As described above, the foldable shelf 1 according to the preferred embodiment of the present invention includes the rotation restricting member provided around the axis A3 so as to hit the front upper shelf 11A when stored, and the shaft so as to hit the rear upper shelf 11B when stored. Since the rotation restricting member 324 provided around A5 is provided, the upper shelf board 11 folded at the time of storage does not swing back and forth. Similarly, the lower shelf board 12 folded at the time of storage does not move back and forth.

  Further, since the connecting members 22 and 32 are formed so as to cover the outer end portions 11AA and 11BA of the front upper shelf board 11A, the rear upper shelf board 11B, the front lower shelf board 12A, and the rear lower shelf board 12B, the movable part. Is not exposed to the outside and easy to use.

  Further, the outer end 11BA of the rear upper shelf board 11B has a substantially U-shaped cross section, and the rotation restricting member 324 is provided on the connecting member 32, and is provided below and inside the axis A5 Since it is located inside the rear upper shelf 11 </ b> B when in use, it does not get in the way when an object is stored in the folding shelf 1. The same applies to the other rotation restricting members.

  Moreover, since the braces 40A and 40B are string-like and are provided so as to intersect two on the left and right sides of the folding shelf 1, the folding shelf 1 can stand stably. Furthermore, the braces 40A and 40B are made of wire ropes, and include the stretchable portion 41 that extends straight when used and contracts in a coil shape when stored, so that the braces 40A and 40B do not loosen when the folding shelf 1 is stored. It is automatically stored.

  Moreover, since the shelf holes 21C and 31C for attaching the shelf stays are formed in the support columns 21 and 31, the middle shelf board 13 can be provided freely.

  Moreover, since the pipe 50 is suspended from the center of the upper shelf board 11, clothes can be hung with a hanger.

  Also, unlike the folding shelf described in Utility Model Registration No. 3153013, the folding shelf 1 does not have a central column, the braces 40A and 40B are string-like, and the middle shelf 13 is removable. Therefore, the folding shelf 1 is lightweight and easy to carry.

[Other embodiments]
Instead of the upper shelf plate 11 and the lower shelf plate 12 formed by bending a thin plate, an upper shelf plate 111 and a lower shelf plate 121 using a thick plate as they are are provided, and instead of the bag-like connecting members 22 and 32, As shown in FIG. 9, plate-like connecting members 225 and 325 may be provided. The connecting members 225 and 325 also function as rotation restricting members. The connecting member (rotation regulating member) 225 is provided around the axis A3 or A4 so as to hit the front upper shelf plate 111A or the front lower shelf plate 121A when the folding shelf 1A is stored. The connecting member (rotation restricting member) 325 is provided around the axis A5 or A6 so as to come into contact with the rear upper shelf plate 111B or the rear lower shelf plate 121B when the folding shelf 1A is stored.

  The rear upper shelf board 111B lies horizontally as shown in FIG. 10 when the foldable shelf 1A is used. However, when the foldable shelf 1A is stored, the rear upper shelf board 111B is 90 around the axis A5 as shown in FIG. The rear surface 111B-1 of the rear upper shelf board 111B hits the connecting member (rotation restricting member) 325. The connecting member (rotation restricting member) 325 is provided in a locus 500A through which one end of the rear upper shelf board 111B passes when the rear upper shelf board 111B is rotated.

  In the said embodiment, although both the upper shelf board 11 and the lower shelf board 12 are foldable, at least one may be foldable. Moreover, the middle shelf board 13 may be foldable.

  Further, the braces 40A and 40B may be provided on only one of the left and right sides. In this case, the surface from which the braces 40A and 40B are eliminated may be used as the front surface of the folding shelf 1. Further, instead of hooking the braces 40A and 40B onto the bolts 21A, 21B, 31A and 31B, the braces 40A and 40B may be welded to the columns 21 and 31. Further, the braces 40A and 40B may be formed of a rod-shaped metal plate instead of the string-shaped wire rope. Further, the braces 40A and 40B may be provided on the left and right ones so that they cross each other.

  In addition, a rotation restricting member may be provided on the connecting members 22 and 32 so that the surface of the upper shelf plate 11 or the lower shelf plate 12 hits the rotation restricting member when stored.

  While the embodiments of the present invention have been described above, the above-described embodiments are merely examples for carrying out the present invention. Therefore, the present invention is not limited to the above-described embodiment, and can be implemented by appropriately modifying the above-described embodiment without departing from the spirit thereof.
