Description

  The present invention relates to a shelf system, a shelf board, a drop-off prevention member, and a shelf system in which a shelf board is detachably attached between a pair of side walls via shelf columns fixed to opposing surfaces of a pair of opposing side walls. Regarding the method.

  A shelf system with a fixed horizontal wall that can be easily constructed is used as storage furniture and store fixtures. A typical shelf system has shelf columns fixed so as to be perpendicular to the floor at two locations on the front side and the rear side of the horizontal wall. A plurality of locking holes are continuously provided in the shelf column in the vertical direction, and the shelf holes are installed so that shelf holders can be hung. Installation of the storage shelf board is completed by placing the storage shelf board on the shelf support. According to this kind of shelf system, simple construction can be realized, but in case of earthquake or when the stored item is pulled out from the storage shelf, the storage shelf moves greatly forward and detaches from the shelf holder. There is a risk of falling.

  As a means for preventing the falling of the shelf board, for example, a groove adapted to the shape of the shelf holder is provided on the shelf board, and the shelf holder is placed in the groove to prevent the shelf board from falling off (see Patent Document 1). A structure is known in which the shelf holder disposed on the front side is L-shaped, and the L-shaped shelf holder is brought into contact with the top surface of the shelf board to prevent the shelf board from falling off (see Patent Document 2). Yes.

  However, in the conventional shelf system, when the shelf board jumps up in the event of an earthquake or pulling out the stored items, the shelf board is easily detached from the shelf holder, and the shelf board is moved by the L-type shelf holder or the like. In the structure to regulate, it does not look good and the designability may be reduced.

  The present invention aims to solve the above-described problems, and provides a shelf system, a shelf board, a drop-off preventing member, and a method for manufacturing the shelf system that can effectively prevent the shelf from falling without impairing the design. The purpose is to do.

  The present invention is a shelf system in which a shelf plate is detachably attached between a pair of side walls via shelf columns fixed to opposing surfaces of a pair of opposing side walls, and the shelf plate faces the shelf columns. A side cuff part, and a drop-off prevention part that fits in a gap formed between the facing surface and the side cuff part by a shelf column that projects from the side face, and protrudes from the side cuff part. And

  In the present invention, the drop-off prevention part protrudes from the side cuff part facing the shelf column, and the drop-off prevention part is a gap formed between the facing surface of the side plate and the side cuff part by the shelf column. It is provided to fit in. In other words, when the fall prevention part is viewed from the opposite side across the shelf column, the fall prevention unit is hidden so as to be hidden behind the shelf column, and the design when viewed from the opposite side is impaired. hard. Furthermore, even if the shelf board jumps up, if the drop prevention unit moves to the shelf column side, the shelf column is long and the shelf column interferes with the drop prevention unit, so that the movement of the shelf plate can be regulated. . As a result, it is possible to effectively prevent the shelf board from falling without impairing the design.

  In addition, it is preferable that a plurality of shelf columns are provided on each of the pair of side walls, and the drop-off prevention unit is disposed between adjacent shelf columns of at least one of the side walls. Since the movement of the drop-off prevention portion in both directions is regulated by both adjacent shelf columns, movement of the shelf board such as jumping up can be more reliably suppressed, and the shelf board can be effectively prevented from falling.

  In addition, the shelf further includes a back wall connected to the pair of side walls, and the shelf board includes a rear side butt portion in contact with the back wall and a front side lip portion opposite to the rear side lip portion, and a drop prevention portion. Is preferably close to the shelf column near the front end of the shelf column. When the shelf column near the front side lip interferes with the drop-off prevention part, this interference part becomes a fulcrum, and a force to lift the rear side lip acts on the shelf. However, the rear end of the shelf board is close to the back wall. Therefore, the lifting of the rear end part is suppressed by interference with the back wall, and the falling of the shelf board can be more effectively prevented.

  In addition, it is preferable that the amount of protrusion of the drop-off preventing portion protruding from the side end is smaller than the thickness of the shelf column. According to this configuration, the drop-off prevention part can be easily accommodated in the gap formed by the shelf columns, which is further advantageous in improving the design. In addition, it is advantageous that the drop-off prevention part is unlikely to interfere with the side wall when the shelf plate is attached.

  In addition, it is preferable that the drop-off prevention portion includes a protrusion adjustment portion that can adjust the protrusion amount from the side end portion. Providing the protrusion adjustment part makes it possible to finely adjust the protrusion amount of the drop-off prevention part while adjusting to the size of the gap, so that the shelf board can be easily prevented from dropping at the installation site.

  In addition, the present invention is a shelf plate that is detachably attached between a pair of side walls via shelf columns fixed to opposing surfaces of a pair of opposed side walls, and a side cuff that faces the shelf columns, And a drop-off prevention part that fits into a gap formed between the facing surface and the side cuff by a shelf column protruding from the facing surface.

  According to this shelf board, the fall from between a pair of side walls which opposes is prevented effectively, without impairing design property.

  The present invention also provides a drop-off prevention member that is attached to a shelf plate that is detachably attached between the pair of side walls via shelf columns that are fixed to the opposing surfaces of the pair of opposing side walls. It is fixed to the side cuff part facing the column and protrudes from the side cuff part, and is fit in a gap formed between the facing surface and the side cuff part by the shelf column protruding from the opposite surface. To do.

  By using the shelf board to which this drop-off prevention member is attached, the shelf board is effectively prevented from falling between a pair of opposing side walls without impairing the design.

  The present invention also relates to a method for manufacturing a shelf system in which a shelf board is detachably attached between a pair of side walls via shelf columns fixed to the opposing surfaces of a pair of opposing side walls. The drop-off prevention part is formed so as to protrude from the side cuff part facing the column, and the drop-off prevention part fits in the gap formed between the opposite surface and the side cuff part by the shelf column protruding from the opposite surface. The shelf board is attached between the pair of side walls.

  With this manufacturing method, it is possible to manufacture a shelf system that can effectively prevent the shelf board from dropping without impairing the design.

  Further, it is preferable that the base plate material is cut into a shelf plate corresponding to the opposing width of the pair of side walls to which the shelf column is fixed, and the drop-off preventing portion is formed at the side cuff of the shelf plate. Since the shelf board can be manufactured by carrying the foundation board material into the site and cutting the foundation board material according to the opposing width of the pair of side walls installed at the site, the versatility is increased, which is advantageous.

  According to the present invention, it is possible to effectively prevent the shelf board from dropping without impairing the design.

  Hereinafter, embodiments of a shelf system according to the present invention will be described in detail with reference to the drawings.

  In recent years, there are various housing styles and frontage settings according to lifestyles, and there is a demand for a shelf system equipped with storage shelves that can be easily processed in the field and does not impair the design of the storage shelves. The shelf system according to the present embodiment is a shelf system that can appropriately respond to such a demand. For example, a shoe shelf, a small shelf for effectively using an upper space of a home appliance such as a washing machine or a refrigerator, or storage in a storage room Available for shelves etc.

  As shown in FIGS. 1, 2, and 3, the shelf system 1 </ b> A according to the present embodiment includes a pair of opposing lateral walls (side walls) 2. Although various shapes and dimensions can be adopted for the horizontal wall 2 in accordance with the house style and the frontage setting, in the present embodiment, for example, a rectangular plate shape is provided such that the long side portion 2a is vertical. Further, the shelf system 1A includes a bottom plate 3 that connects the lower side portions (short side portions) 2b of the pair of horizontal walls 2 and a back plate (back wall) that connects the long side portions 2a on the back side of the pair of horizontal walls 2. 4). The bottom plate 3 is sandwiched between the horizontal walls 2 and fixed to the horizontal walls 2 with an adhesive, screws, or the like. Further, the back plate 4 is sandwiched between the horizontal walls 2 and fixed to the horizontal wall 2 via an adhesive, screws, L-shaped hardware, or the like. The front surfaces of the pair of horizontal walls 2, that is, the front surfaces facing the back plate 4 are opened, and the upper surfaces are also opened. The horizontal wall 2, the bottom plate 3, and the back plate 4 are appropriately subjected to a cosmetic treatment such as a cloth being pasted.

  A plurality of shelf columns 5 and 6 are fixed to opposing surfaces (inner surfaces) 2 c of the pair of horizontal walls 2. In the present embodiment, the front shelf column 5 is fixed along the front long side portion 2a of one horizontal wall 2, and the rear shelf column 6 is fixed along the rear long side portion 2a. A pair of shelf columns 5 and 6 are also fixed to the other lateral wall 2 so as to be symmetrical. That is, in this embodiment, a total of four shelf columns 5 and 6 are arranged.

  The shelf columns 5 and 6 are long members that are long in the vertical direction, and protrude from the inner surface 2c into a rectangular cross section. Further, the shelf pillars 5 and 6 are provided with a plurality of locking holes 50 for fixing the shelf receiver 7, and the plurality of locking holes 50 are arranged along the longitudinal direction of the shelf columns 5 and 6. Arranged at intervals. The locking hole 50 has a large-diameter circular hole 51 and a small-diameter slit 52 extending from the lower portion of the circular hole 51. The shelf receiver 7 has a substantially columnar shelf mounting part 71 and a head 72 connected to the shelf mounting part 71 via a neck 73 having a small diameter. The shelf receiver 7 is attached by inserting the head 72 into the circular hole 51, sliding the neck 73 downward along the slit 52, and hooking the head 72 from the back side. The shelf receiver 7 is attached to each of the four shelf pillars 5 and 6 while adjusting the height to be the same.

  A storage shelf board (hereinafter referred to as “shelf board”) 9 according to the present embodiment has a rectangular shape formed so as to fit between a pair of horizontal walls 2, a pair of front surfaces 91 serving as an upper surface and a lower surface, and a long side A pair of side end portions 92A and 92B and a pair of short end side end portions 93 are provided. The shelf board 9 is inserted between the horizontal walls 2 such that a pair of side ends (hereinafter referred to as “lateral side ends”) 93 are opposed to the shelf columns 5 and 6, and placed on the shelf receivers 7 at four locations. Placed. In this state, of the pair of long end side end portions 92A and 92B, one end portion (hereinafter referred to as “rear end end portion”) 92B is close to the back plate 4. This proximity means that not only the state of being in contact but also the state of being separated by several millimeters is allowed as an error. Of the pair of long-side end portions 92A and 92B, the end portion 92A opposite to the rear end portion 92B (hereinafter referred to as “front end end portion”) 92A is open.

  As shown in FIG. 3 and FIG. 4, the shelf columns 5 and 6 protrude inward from the inner surface 2 c of the lateral wall 2, and when the shelf plate 9 is placed on the shelf holder 7, the shelf columns 5 and 6. A gap S is formed between the side mouth end 93 and the inner surface 2c of the lateral wall 2 by the amount of protrusion. A drop-off prevention unit 10 is provided at the side cuff 93 of the shelf board 9 so as to fit in the gap S. More specifically, the drop-off prevention unit 10 is between the pair of front and rear shelf columns 5 and 6, and the drop-off prevention unit is located at a position where the distance d from the front shelf column 5 is smaller than the allowable movement distance SD of the shelf plate 9. 10 is provided.

  The movement allowable distance SD of the shelf board 9 is a distance that the shelf board 9 is not detached from the rear shelf holder 7 even if the shelf board 9 moves to the opened front side. Specifically, first, when the shelf board 9 is installed at a regular position, that is, in this embodiment, the state in which the rear side end 92B of the shelf board 9 is close to the back board 4 is used as a reference. Next, in this reference state, a front limit (hereinafter referred to as a “support limit portion”) P that can support the shelf 9 by the shelf receiver 7 of the rear shelf column 6 is defined. The distance from the rear end portion 92B of the shelf board 9 to the support limit portion P is the movement allowable distance SD of the shelf board 9.

  This is a case where the shelf board 9 moves forward by providing the dropout prevention section 10 at a position where the distance d from the front shelf column 5 to the dropout prevention section 10 is smaller than the allowable movement distance SD of the shelf board 9. Even in this case, the front shelf column 5 interferes with the drop-off prevention unit 10, and the shelf plate 9 can be reliably prevented from falling. In addition, since the shelf receiver 7 according to the present embodiment has a circular cross section, the support limit portion P is an upper end portion of the shelf receiver 7, that is, a portion that contacts the lower surface (front surface) 91 of the shelf board 9. Further, in the present embodiment, a description has been given in a mode in which a pair of front and rear shelf columns 5 and 6 are provided, but an intermediate shelf column is further provided between the front and rear shelf columns 5 and 6, and a front shelf column is provided. In the case where the shelf board 9 can be supported by the shelf holders 7 attached to the intermediate shelf pillars 5 and 5, the “support limit portion” can be defined by the shelf holders 7 attached to the intermediate shelf pillars.

  In particular, in the case of this embodiment, the drop-off prevention unit 10 is provided so as to be close to the front shelf column 5. Regarding the meaning that the drop-off prevention unit 10 is close to the shelf column 5, not only the state where the drop-off prevention unit 10 is in contact with the shelf column 5 but also a state where it is separated by several millimeters is allowed as an error. is there.

  Further, the drop-off prevention part 10 is formed by fixing the drop-off prevention member 21 to the side end part 93. The drop-off prevention member 21 has, for example, an R shape or a chamfered shape so as not to damage the cloth or the like, and is made of metal or resin.

  For example, the dropout prevention member 21 according to the present embodiment is a push pin, and includes a head portion 21a that abuts on the side cuff portion 93 and a needle portion 21b that protrudes from the back surface of the head portion 21a. Further, the head 21a is flat on the side end portion 93 side, and has a convex curved shape in which the side facing the lateral wall 2 is curved. The height dimension of the head portion 21a, that is, the protrusion amount L from the side end portion 93 is the thickness T of the shelf columns 5, 6, that is, the dimension in which the shelf columns 5, 6 protrude inward from the inner surface 2c of the lateral wall 2. The drop-off prevention member 21 does not interfere with the horizontal wall 2 in a state where the shelf plate 9 is placed on the shelf support 7 and is devised so as to fit in the gap S formed by the shelf columns 5 and 6. ing.

  The drop-off prevention member may be another modified example. For example, a tapping screw or a wood screw or the like that has a head (projecting part) that protrudes in a convex curved shape such as a pan head or a truss head is used. The prevention member 22 (refer FIG. 6) may be sufficient. In the case of the screw-type dropout prevention member 22, the protrusion adjusting portion 22b that is a screw shaft that is actually screwed to the side cuff portion 93 of the shelf board 9 functions as a front opening adjusting mechanism, and the screwing amount of the protrusion adjusting portion 22b The amount of protrusion of the head portion 22a from the side end portion 93 can be adjusted. In other words, according to the drop-off prevention part 10 formed using the screw-type drop-off prevention member 22, the drop-off prevention part 10 has the protrusion adjustment part 22 b, so that it falls off according to the frontage dimension when the shelf plate 9 is stored between the horizontal walls 2. The protrusion amount of the prevention part 10 can be adjusted suitably.

  Further, as another modified example of the dropout prevention member, an elastic dropout prevention member 23 (see FIG. 7) using a spring may be used. The elastic drop-off prevention member 23 includes a head portion 23a that abuts against the inner surface 2c of the horizontal wall 2, a screw shaft portion 23b that is screwed into the side cuff portion 93 of the shelf board 9, a screw shaft portion 23b, and the head portion 23a. And a coil spring portion 23c for connecting the two. In the case of the elastic drop-off prevention member 23, the protrusion adjusting portion 23d composed of the screw shaft portion 23b and the coil spring portion 23c functions as a frontage adjusting mechanism, and the side of the head portion 23a is controlled by the amount of screwing of the screw shaft portion 23b. The amount of protrusion from the mouthpiece 93 can be adjusted. Further, when the shelf plate 9 is actually placed on the shelf holder 7, the coil spring portion 23c is contracted so that the amount of protrusion can be substantially adjusted. According to the dropout prevention part 10 formed using the elastic dropout prevention member 23, the dropout prevention part 10 has the protrusion adjustment part 23 d, so that the dropout prevention part is matched to the frontage dimension when the shelf plate 9 is stored between the horizontal walls 2. The amount of protrusion of 10 can be adjusted appropriately.

  Next, a manufacturing method of the shelf system 1A will be described. In the present embodiment, the pair of shelf columns 5 and 6 are installed so that the shelf columns 5 and 6 are on the inner surface (opposing surface) 2c side, and the bottom plate 3 and the back plate 4 are fixed. On the other hand, the shelf board 9 processed according to the opposing width dimension of a pair of horizontal wall 2 is prepared, and the drop-off prevention part 10 is formed so as to protrude from the side cuff part 93 of the shelf board 9. Next, a shelf holder 7 is attached to each of the four shelf pillars 5 and 6, and the shelf board 9 is placed on the shelf holder 7 so that the drop-off prevention unit 10 fits in the gap S formed by the shelf pillars 5 and 6. Let As a result, the shelf board 9 is detachably attached between the pair of lateral walls 2, and the shelf system that can effectively prevent the shelf board 9 from falling without impairing the design when viewed from the front. 1A is completed.

  In addition, the shelf board 9 is not limited to the case where it prepares beforehand in a factory etc. (a place different from a construction site), For example, the shelf system 1A can also be manufactured with the manufacturing method called free cut. . Specifically, a base board material to which a decorative paper, a decorative sheet, etc. are applied and subjected to a makeup process is manufactured in a factory or the like, and the base board material is transported to the site. At the site, a pair of horizontal walls 2 and the like are installed as appropriate, the opposing width of the pair of horizontal walls 2 is measured, and the base plate material is cut into a shelf board 9 corresponding to the opposing width. Next, the shelf system 1A may be manufactured by forming the drop-off prevention part 10 at the side cuff part 93 of the shelf board 9 and installing the shelf board 9 on which the drop-off prevention part 10 is formed between the pair of horizontal walls 2. it can. This manufacturing method is advantageous in that versatility is increased because the shelf plate 9 can be manufactured by cutting the base plate material in accordance with the opposing width of the pair of horizontal walls 2 installed in the field.

  Next, effects of the shelf system 1A according to the present embodiment will be described in comparison with other shelf systems and the like according to the comparative form.

  For example, in a shelf system that restricts the movement of the shelf board forward by attaching an L-shaped shelf holder to the front shelf column (see FIG. 9), the shelf is the rising piece that rises L-shaped from the placement part of the shelf board. Regulates forward movement of the plate. Since the rising piece is visible from the front, the rising piece is conspicuous and the design property is easily impaired. Therefore, if the design property is important, it is necessary to reduce the height dimension (length dimension) of the rising piece. However, if the height dimension (length dimension) of the rising piece is reduced, the shelf board is likely to drop off, and in particular when the force is applied from the up and down direction. Further, when the shelf column is displaced from the normal position and as a result, the L-shaped shelf holder is displaced, the rising piece interferes with the shelf board. That is, the precision which attaches a shelf column in mm unit is required, and the simplicity of construction was easy to fall.

  In addition, in a shelf system in which a fall prevention bracket is attached to the bottom surface of the shelf so as to interfere with the shelf holder, there is a possibility that the fall prevention bracket may get over the shelf holder, effectively preventing the shelf from falling off. It was difficult.

  In addition, in a shelf system that prevents the shelves from falling off by applying grooves to the shelves according to the shape of the shelves and placing the shelves in the grooves, the shelves come out of the grooves when the shelves jump up. There was a possibility that it was difficult to effectively prevent the shelves from falling off. Furthermore, in this shelf system, it is necessary to process the shelf board into a predetermined frontage size at the site, and further to perform grooving according to the shape of the shelf holder, which may reduce the ease of construction. .

  With respect to these shelf systems, in the shelf system 1A according to the present embodiment, when the drop-off prevention unit 10 is viewed from the front side, the drop-off prevention unit 10 is concealed behind the shelf column 5, and the front side The design characteristics when the shelf system 1A is viewed from the top are hardly damaged. Furthermore, even if the shelf plate 9 is forced from below and the shelf plate 9 jumps up, the shelf column 5 is long in the vertical direction, so the shelf column 5 contacts (interferences) with the drop-off prevention unit 10 and the shelf plate 9 moves forward. There is no fear of jumping out. That is, in the shelf system 1 </ b> A according to the present embodiment, both improvement in design and effective prevention of the shelf board 9 from falling can be achieved. Moreover, according to the shelf board 9 which concerns on this embodiment, it is hard to leave | separate from the state attached between a pair of opposing horizontal walls 2, and fall is prevented effectively.

  Moreover, in this embodiment, the fall prevention part 10 can be formed by fixing the fall prevention members 21, 22, and 23 to the side cuff part 93 of the shelf board 9, and the shelf board 9 with the fall prevention part 10 is formed. This can be realized by installing between a pair of horizontal walls 2. Therefore, further processing such as grooving is not necessary for the shelf plate 9. Further, if the shelf columns 5 and 6 are attached at positions where the shelf plate 9 can be appropriately supported by the shelf holder 7, the shelf columns 5 and 6 can be positioned between the shelf columns 5 and 6 without fine adjustment. It is sufficient to install the drop-off prevention unit 10 at an appropriate position. That is, the drop-off prevention part 10 can be formed independently of the installation of the shelf columns 5 and 6, and only the drop-off prevention part 10 needs to be adjusted as necessary. Can be effectively prevented.

  Moreover, in this embodiment, since it is not necessary to provide the groove | channel etc. for drop-off prevention in the upper and lower surfaces 91 of the shelf board 9, it can utilize as a reversible aspect, for example. Specifically, a decorative paper or a decorative sheet with a different pattern is pasted on the upper and lower surfaces 91 (makeup treatment is performed), and the both sides can be used by turning them over as appropriate, or the top surface (surface ) When 91 is dirty, the lower surface (front surface) 91 with relatively little dirt can be used as the upper surface by turning it over. In this case, the gap S in which the drop-off prevention unit 10 is accommodated is a gap S formed by the shelf columns 5 and 6 fixed to the opposite side wall 2.

  Further, in the shelf system 1A according to the present embodiment, the dropout prevention unit 10 is provided only on the one side wall 2 side. Therefore, when the shelf board 9 is inserted between the pair of side walls 2 and installed, the drop-off prevention unit 10 is not obstructive, which is advantageous in terms of construction. However, it is also possible to provide the drop-off prevention part 10 on both the side walls 2, and in this case, the shelf pillars 5 fixed to both the side walls 2 interfere with the drop-off prevention part 10, so that the shelf plate 9 is dropped. Can be effectively prevented.

  In the shelf system 1 </ b> A according to the present embodiment, the drop-off prevention unit 10 is disposed between the pair of shelf columns 5 and 6 that are adjacent to each other before and after being fixed to the horizontal wall 2. Here, since the back plate 4 is provided in the present embodiment, the backward movement of the shelf plate 9 is substantially restricted by the back plate 4. However, for example, even in the case where the back plate 4 is not provided and the rear is opened, and the like, as in this embodiment, the drop-off prevention unit 10 is provided between the front and rear shelf columns 5 and 6. Since the movement of the drop-off prevention unit 10 in both the front and rear directions is regulated by the front and rear shelf columns 5 and 6, the movement of the shelf board 9 can be more reliably suppressed, and the fall of the shelf board 9 can be effectively performed. Can be prevented. In addition, in the case of the aspect provided with the back board 4, from the meaning of restrict | limiting the movement to the front of the shelf board 9 without impairing the designability, the fall-off prevention part 10 is provided with the rear shelf column 6 and the back board. 4 may be provided.

  Further, the dropout prevention unit 10 according to the present embodiment is close to the shelf column 5 near the front side end 92A, and the rear end 92B of the shelf 9 is close to the back plate 4. This operation will be described with reference to FIG. For example, when an external force such as an earthquake is applied and the shelf board 9 is displaced forward, basically the shelf column 5 interferes with the drop-off prevention unit 10 to restrict the forward movement of the shelf board 9. Is done. However, the interference portion serves as a fulcrum, and a force to lift the rear side end 92B may act on the shelf 9. However, since the rear end portion 92B of the shelf board 9 is close to the back wall, the lifting of the rear end section 92B is suppressed by interference with the back plate 4, and the fall of the shelf board 9 is more effectively prevented. it can.

  Moreover, the protrusion amount L (see FIG. 3) of the dropout prevention unit 10 according to the present embodiment is smaller than the thickness T of the shelf columns 5 and 6. As a result, the drop-off prevention unit 10 can be easily accommodated in the gap S formed by the shelf columns 5 and 6, which is further advantageous in improving the design. Further, when the shelf board 9 is attached, it is advantageous that the drop-off prevention part 10 does not easily interfere with the horizontal wall 2 and the like.

  Further, by using the protrusion adjusting portion 22b or the protrusion preventing portion 10 provided with the protrusion adjusting portion 22b that can adjust the protrusion amount L from the side end portion 93, the protrusion of the drop preventing portion 10 is adjusted in accordance with the size of the gap S. The amount can be finely adjusted, and it is easy to optimize the prevention of falling of the shelf board 9 at the installation site. Moreover, even when the base plate material is cut at the site to form the shelf plate 9, even if the length of the shelf plate 9 becomes shorter than the opposing width of the pair of lateral walls 2, the drop-off prevention unit 10. This can be done by adjusting the amount of protrusion.

  Next, a shelf system 1B according to the second embodiment will be described with reference to FIG. In the shelf system 1B according to the present embodiment, the same elements and structures as those of the shelf system 1A are denoted by the same reference numerals, and detailed description thereof is omitted.

  The present embodiment is, for example, a shelf system 1B provided in a building, and the pair of horizontal walls 2A are not plate-shaped but are formed as part of the interior wall surface of the building. Moreover, in this embodiment, it is a multistage shelf system 1B, and a plurality of shelf boards 9, for example, three or more shelf boards 9 are installed. A dropout prevention portion 10 is formed on one or both of the side end portions 93 of all the shelf boards 9.

  According to the shelf system 1B according to the present embodiment, the falling of the shelf board 9 can be effectively prevented without impairing the design, and according to the manufacturing method of the shelf board 9 and the shelf system 1B, the design can be achieved. Thus, it is possible to realize a shelf system 1B that can effectively prevent the shelf 9 from falling without impairing the performance.

  As mentioned above, although this invention was demonstrated based on embodiment, this invention is not limited only to said embodiment. For example, in the above-described embodiment, an example in which the drop-off prevention unit 10 is provided only in one side cuff part 93 of the pair of left and right side cuff parts 93 of the shelf board 9 is illustrated. The part 93 may be provided with the drop-off preventing part 10. In addition, instead of providing the single dropout prevention part 10 in one side cuff part 93, a plurality of dropout prevention parts 10 may be provided. For example, one of the plurality of dropout prevention parts 10 may be provided. The part 10 may be provided in the vicinity of the front shelf column 5, and the other drop prevention unit 10 may be provided in the vicinity of the rear shelf column 6.

  EXAMPLES Hereinafter, although an Example demonstrates this invention in detail, this invention is not limited to these examples.

[Example 1]
The shelf system according to Example 1 corresponds to the shelf system according to the first embodiment described above, and uses a metal push pin as a drop-off preventing member. In addition, the push pin was fixed to the side cuff so as to be close to the front shelf column. In this example, an external force of about 5 kg was applied in the front-rear direction, the left-right direction, and the up-down direction, but it was verified that the shelf board was stably held and did not fall off.

[Comparative Example 1]
9 shows a shelf system according to Comparative Example 1, FIG. 9 (a) is a diagram corresponding to FIG. 2 for comparison, and FIG. 9 (b) is a line bb in FIG. 9 (a). FIG.

  In the shelf system 100 according to the comparative example 1, the L-shaped shelf holder 107 is attached to the front shelf column. The L-shaped shelf receiver 107 includes a rising piece 107a for restricting the forward movement of the shelf board 109, and the rising piece 107a is visible from the front. In the shelf system 100 according to the comparative example 1, the rising pieces 107a are conspicuous and the design properties are easily lost. Therefore, if importance is placed on the design, it is necessary to reduce the height dimension (length dimension) of the rising piece 107a. However, if the height dimension (length dimension) of the rising piece 107a is reduced, the shelf board 109 is likely to drop off, and particularly when the force is applied in the vertical direction, the shelf board 109 is easily dropped off. That is, in the shelf system 100 according to the comparative example 1, it is substantially difficult to achieve both the effects of improving the design and preventing the shelves from falling off.
