According to this configuration, the rising piece is provided upright on the rear end edge of the upper plate portion over the entire length, so that the rising piece reliably prevents the fall of sand, dust, etc. from the rear side, and the rising piece. Due to the reinforcing rib action of the piece, the bending deformation of the shelf body is also prevented. Further, since a concave step portion having a shape capable of accommodating the rising piece is formed at a lower corner portion of the rear edge of the lower plate portion, the rising piece is accommodated in the concave step portion, and the shelf board can be loaded and packed without hindrance. .

[0010] It is preferable that a metal reinforcing bar be provided along the bent groove. With this configuration, since the metal reinforcing bar is provided along the bent groove, the bending deformation of the shelf body is reliably prevented, and the dowel receiving recesses at both ends of the bent groove are formed with the dowel convex. The shelf plate body is securely locked on the part and does not fall off, and the metal reinforcing bar is not exposed to the outside, so that the appearance is not impaired.

It is preferable that a rib is integrally formed on the front edge of the upper plate portion so as to be integrally raised. In this case, the ribs prevent the stored items from slipping. Here, if the height dimension of the rib is appropriately set, the rib is less likely to be damaged even when a stored item is taken in and out. In addition, if the side surface is appropriately inclined, dust and the like can be easily swept out, and does not hinder cleaning.

[Second Embodiment] FIGS. 5 and 6 show a second embodiment of the present invention. FIG. 5 is a side view of the shelf board according to the present embodiment as viewed from its foreface. FIG. 6 is a partially enlarged view showing the groove of the shelf board according to the present embodiment. The shelf 210 according to the present embodiment includes a shelf main body 212 and a reinforcing bar 214 positioned inside the shelf main body 212 to reinforce the shelf main body 212. The shelf main body 212 is a member made of synthetic resin integrally formed by extrusion molding.

More specifically, the shelf main body 212 includes an upper plate 211 and a lower plate 213 parallel to each other, a side plate 217 connecting the upper plate 211 and the lower plate 213 at both ends thereof, The plate portion 211 and the lower plate portion 213 are connected and both side plate portions 217 are connected.
A plurality of rib pieces 218 arranged so as to have a gap therebetween
And Here, each of the side plate portions 217 is
Each of them constitutes a front plate portion and a rear plate portion of the shelf main body 212.

The rib piece 218 adjacent to the side plate 217
A rib groove 216 having a downward opening is formed between the rib piece 218 and the other rib piece 218 adjacent to the rib piece 218. That is, the bent grooves 216 are formed one by one near both ends in the cross section of the shelf board body 212. When the bent groove 216 is formed, a locking portion 220 for preventing the reinforcing bar 214 from dropping is formed at the lower edge of the two rib pieces 218 sandwiching the bent groove 216 on the bent groove 216 side. That is, this locking portion
Reference numeral 220 is for preventing the reinforcing bar 214 from falling off from the bent groove portion 216 when the reinforcing bar 214 described later is inserted and fixed in the bent groove portion 216.

The upper plate 211 and the lower plate of the shelf main body 212
The 213, the side plate portion 217, the rib piece 218, and the locking portion 220 are integrally formed by extrusion molding. The reason why the plurality of rib pieces 218 are formed at appropriate intervals inside the shelf body 212 is to increase the bending strength in the longitudinal direction of the shelf body 212 and to form a hollow portion between the rib pieces 218. This is because the hollow portion 215 is formed to save the synthetic resin material and reduce the weight.

Next, the reinforcing bar 214 will be described. The reinforcing bar 214 is a long iron member having a U-shaped cross section, and is formed to have the same length as the longitudinal length of the shelf main body 212. The outer diameter of the reinforcing bar 214 is slightly smaller than the inner diameter of the bent groove 216. The reinforcing bar 214 formed in this manner is inserted and fixed from the fore-edge surface of the shelf body 212 with the opening part facing downward. In this case, a slight gap is formed between the lower edge of the reinforcing bar 214 and the locking portion 220 as shown in FIG. This gap is provided by the reinforcing bar 214
This is for absorbing a bending error in the longitudinal direction of the reinforcing bar 214 when inserting the fixing bar into the bending groove 216.

In order to provide the shelf board 210 thus formed at the place where the shelf board is to be installed, the shelf board 210 is supported at a portion of the shelf board where the front edge of the shelf board 210 is opposed to both fore-edge surfaces. The cylindrical shelf support member 230 for the
Protrude in the fore-edge direction. That is, since the reinforcing bar 214 is formed in a U-shape with a small cross section so that the lower part becomes an opening, and is inserted and fixed in the bent groove part 216 of the shelf main body 212 with the opening directed downward. By hooking the opening of the reinforcing bar 214 on the shelf support member 230, the shelf 210 can be fixed to the shelf installation location.
Here, the shelf support member 230 is a dowel protrusion projecting from the inner surface of the mounting side plate to which the shelf 210 is attached. The shelf support member 230 is provided at an appropriate position of the shelf installation location so that when the shelf 210 is installed, the play of the shelf 210 can be prevented.

Next, the operation according to the present embodiment having such a configuration will be described with reference to FIG. Shelf board body 21
2 is formed by extrusion molding, the upper plate portion 211, the lower plate portion 21
3. The side plate part 217, the rib piece part 218 and the locking part 220 are integrally formed. That is, the length of the shelf body 212 in the longitudinal direction can be arbitrarily formed.

Further, since a plurality of rib pieces 218 are provided between the upper plate 211 and the lower plate 213, the bending strength in the longitudinal direction of the shelf main body 212 is increased. To assemble the shelf 210, it is only necessary to insert the reinforcing bar 214 into the bent groove 216 of the extruded shelf main body 212 from the front side of the shelf main body 212. In this case, since the locking portion 220 is provided at the lower edge of the two rib pieces 218 sandwiching the bent groove portion 216, the lower edge of the reinforcing bar 214 is locked by this locking portion 220, and the reinforcing bar 214 Does not fall out of the bent groove portion 216.

When the shelf board 210 is installed at a predetermined location in a storage space such as a clog box, the shelf board 210 is mounted on the shelf support member 230 formed at a predetermined position of the installation location.
By simply placing both ends of the reinforcing bar 214 from above, the openings at both ends of the reinforcing bar 214 can be hooked on the shelf supporting member 230, and the installation of the shelf 210 can be completed easily. Even if a load is applied to the shelf board 210 thus installed, the reinforcing bar 21
4 is made of iron, so it is strong against concentrated loads.
2 can sufficiently secure the bending strength in the longitudinal direction.

Next, effects of the present embodiment will be described.
Since the shelf main body 212 is extruded in the longitudinal direction of the shelf main body 212, the shelf main body 212 having an arbitrary length can be manufactured using the extrusion having the width. Thereby, there is also an effect that a member can be shared as a shelf board of another storage furniture or the like which can be used in the horizontal width. That is, it is possible to manufacture many types of shelves having an arbitrary length from one mold for extrusion.

When the shelf 210 is supported by the shelf support member 230, the concentrated load applied by the shelf support member 230 can be received by the reinforcing bar 214 inserted and fixed in the bent groove 216. Therefore, this concentrated load is
2, the upper plate 211 and the lower plate 213 of the shelf main body 212 can be formed to be thin, so that the weight of the shelf main body 212 can be reduced and the synthetic resin material can be saved. . Further, since the reinforcing bar 214 is made of iron, a predetermined strength can be ensured.

Further, since the bent groove portion 216 is provided in the shelf main body 212, the reinforcing bar 214 can be easily fixed to the shelf main body 212 simply by inserting the reinforcing bar 214 from the fore side of the shelf main body 212. Further, since the locking portion 220 is provided on the shelf body 212,
The reinforcing bar 214 is locked by the locking portion 220 and the reinforcing bar 21
4 does not fall off the shelf main body 212. Further, since a slight gap is formed between the lower end edge of the reinforcing bar 214 and the locking portion 220, there is a bending error in the longitudinal direction of the reinforcing bar 214 when the reinforcing bar 214 is inserted into the bent groove portion 216. Can be absorbed, and the work of inserting and fixing the reinforcing bar 214 can be performed smoothly.

Further, since a plurality of thin plate-like rib pieces 218 are provided along the longitudinal direction inside the shelf board body 212,
It becomes difficult to bend against the load distributed along the longitudinal direction of the 212, and the bending strength of the shelf main body 212 can be secured. Further, since the lower part of the reinforcing bar 214 is opened, the shelves 21
With respect to the shelf support member 230 provided in the portion where
The opening of the reinforcing bar 214 can be hooked and fixed to the shelf supporting member 230 only by placing the reinforcing bar 214 from above the shelf supporting member 230, so that the assembly of the shelf 210 is easy.

The reason why the plurality of rib pieces 318 are formed at appropriate intervals inside the shelf body 312 is to increase the bending strength in the longitudinal direction of the shelf body 312 and to form a hollow portion between the rib pieces 318. This is because the hollow portion 315 is formed to save the synthetic resin material and reduce the weight. Note that the reinforcing bar 314 is the same as the reinforcing bar 214 in the above-described second embodiment, and a description thereof will be omitted.

In the present embodiment having such a configuration, the same operation as the above-described second embodiment is obtained, and the following operation is also performed. That is, the storage auxiliary member 340
Is fixed by inserting its upper end into the groove 346 for the auxiliary storage member and engaging it with the locking portion 344 for the auxiliary storage member. Therefore, the storage auxiliary member 340 is locked by the storage auxiliary member locking portion 344 and the shelf main body 312 is locked.
Never fall off. Further, since the storage assisting member locking portion 344 is reinforced by the reinforcing portion 350, the storage assisting member 340 is locked and fixed to the storage assisting member locking portion 344, and a small cover is placed on the storage assisting member 340. Even if a stored object is placed, no problem occurs in the strength of the storage assisting member locking portion 344.

According to the above-described third embodiment, the same effects as those of the above-described second embodiment can be obtained, and the storage auxiliary member 340 can be locked and fixed to the storage auxiliary member locking portion 344. Therefore, the following effects can be obtained. In other words, when the shelf board 310 is used for storage furniture, a shoe box, or the like, the shelves 310 have to be mixed and housed with objects having different heights such as boots and boots. If not, the storage auxiliary member 340 is fixed to the lower part of the shelf plate 310, which is one step higher than the shelf plate 310, and another small object to be stored such as short boots with a small height is stored in the storage auxiliary member 340. it can. This makes it possible to effectively use the storage space above the small storage object that has been wasted without being used conventionally.

Further, if a small storage object such as a desiccant or an insect repellent is placed on the storage auxiliary member 340, the storage space that has not been conventionally used and is wasted can be effectively used as in the above case. Will be able to do it. In addition, since the storage assisting member engaging portion 344 is reinforced by the reinforcing portion 350, the storage assisting member 340 can be used as the storage assisting member engaging portion 34.
4 and the small storage object is placed on the storage auxiliary member 340, the storage auxiliary member
Not only does not cause any problem in the strength of the shelves, but also has an effect that the strength of the entire shelf main body 312 is ensured.

The upper surface of the upper plate 311 and the rib piece
Since a sink prevention groove 360 is formed at a position corresponding to 318, there is also an effect that so-called "sink" during extrusion molding can be prevented. Next, variations of the present invention will be described. In the above embodiment, the reinforcing portion 350 is described as being formed so as to integrally connect the storage assisting member locking portion 344 and the rib piece portion 318. And the upper plate portion 311 may be integrally connected.

In the above embodiment, the shelf support member 330 has been described as having a columnar shape. However, if the shelf plate support member 330 has a predetermined strength and can support the reinforcing bar 314, it is limited to a columnar shape. Absent. Further, although the reinforcing bar 314 is described as being made of iron, it can be made of aluminum or the like if a predetermined strength can be ensured, and this can contribute to a reduction in the weight of the entire shelf board 310.

Although not shown in the above embodiment,
When the shelf board 310 is used in a clog box or the like, by providing the hollow portion 315 with a desiccant or a fragrance, there is an effect that the clog box or the like can be used comfortably.
