Embodiments of the present disclosure will be described below with reference to the accompanying drawings.
First, the basic configuration of the shelf unit 1 according to this embodiment will be described.

The bookshelf unit 1 includes a plurality of plate-like materials 1A, each of which has plate-like portions 10 and 30 that are substantially rectangular in plan view and are made of non-magnetic material. Ferromagnetic plates 18 and 38 are disposed on at least one of all plate surfaces 10 and 30.

As the plurality of plate materials 1A, the back plate 2, shelf plates 3 and 4, side plates, top plate, door plate, etc. are assumed. An example of a shelf unit 1 according to the present embodiment described below has a back plate 2 and two shelf boards 3 and 4 as a plurality of plate materials 1A. Each of the rear plate 2 and the two shelf boards 3 and 4 includes plate-shaped portions 10, 30, and 30A having different dimensions. The base materials of the plate-like parts 10, 30, and 30A are all made of aluminum.

As the material for the ferromagnetic plates 18 and 38, a steel plate (hot-dip galvanized steel plate 38d, see FIG. 3(c)) is used in this embodiment, but the material is not limited to this, and materials include iron, cobalt, and nickel. , and alloys thereof.

Next, details of the shelf unit 1 will be explained based on FIGS. 1 to 8. The shelf unit 1 shown in these figures is a group of members that can be installed as a shelf on a mounting base 5 indoors, such as a kitchen wall.

FIG. 1(a) is an exploded perspective view of the shelf unit 1 according to the present embodiment, and FIG. 1(b) is a schematic side view showing the shelf unit 1 in a state where it is attached as a shelf.

As shown in FIGS. 1(a) and 1(b), the shelf unit 1 according to the present embodiment is configured with a plurality of plate-like materials 1A, and is used by being attached to a wall surface (mounting base 5) such as a kitchen. be done. The plate material 1A includes one back plate 2 and two shelf boards 3 and 4. The shelf unit 1 includes side lids 70A, 70B and a blind lid 60 in addition to the plurality of plate materials 1A as constituent materials. Note that in FIG. 1(a), the side lids 70A and 70B are shown attached to the plate material 1A.

The back plate 2 is a plate material 1A having a rectangular plate surface, and is a member fixed to a wall surface with the longitudinal direction of the plate portion 10 aligned with the lateral direction (the direction in which the wall surface is viewed). Furthermore, connecting portions (fitting receiving portions 20) for connecting the shelf boards 3 and 4 are provided at both ends of the back plate 2 in the transverse direction (vertical direction in the attached state).

The total length of the shelf boards 3 and 4 in the longitudinal direction of the board surface is approximately the same as the total length of the board surface of the back board 2 in the longitudinal direction. Attached to the connecting part. A connecting portion (fitting convex portion 40) for connecting to the back plate 2 is provided at one end in the transverse direction of the plate surface of the shelf board 3 (the rear part in the attached state).

Further, as shown in FIG. 1(b), steel plates (ferromagnetic plates) 18 and 38 with a thickness of approximately 0.4 mm are installed on the front side of the rear plate 2 and the lower surface side of the lower shelf board 3, respectively. has been done. The steel plates 18 and 38 are not limited to this thickness, but should be approximately 0.2 mm to 1 mm so that the overall weight of the shelf does not become too heavy and the adhesion force of the magnet does not decrease too much. This is desirable.

Since the structure has steel plates 18 and 38 inside, magnetic hooks or magnetic clips can be attached to the front of the back plate 2 and the bottom surface of the lower shelf plate 3 when installed as a shelf to store items. You can hang it up or use a magnet to hold notes or other papers. When used as a kitchen shelf, for example, a wine glass can be hung from the lower surface of the lower shelf board 3. It is also possible to create a design by attaching a magnetic sheet with a design on the surface to the front of the back plate 2.

In this way, since the plate-shaped body having the plate-shaped parts 10, 30, and 30A made of metal (non-magnetic material) as a base material is used, a sturdy shelf can be formed. If the shelf is made of wood, side plates are required to ensure strength, but since the plate parts 10, 30, and 30A are made of metal, the shelf can maintain strength even without side plates and has excellent load-bearing performance. . Furthermore, even when used as a shelf in a kitchen where steam or steam is likely to be generated, there is little risk of deformation due to moisture unlike wood-based products, and it can be used safely for a long period of time.

Furthermore, since aluminum is used as the non-magnetic material in this embodiment, it is lightweight and easy to handle. In particular, as will be explained below, the plate portions 10, 30, 30A are hollow and therefore light, and can prevent the back plate 2 from peeling off due to its own weight and the shelf board 3 from sagging due to its own weight.

In particular, since the shelf unit 1 of this embodiment does not have side plates, the weight of the entire shelf can be reduced, and costs can also be reduced. Since there are no side plates, it also has the advantage of making it easier to place and take out items.

Note that, as will be described later in the description of FIG. 3(c), the aluminum plate 31a is an aluminum layer with a coating formed on one surface thereof. Further, the steel plates 18 and 38 are made of a steel plate layer having a hot-dip galvanized steel plate 38d as a base material and resin sheets (films) arranged on both sides thereof. In this specification, except for the description of FIG. 3(c), "aluminum" refers to an aluminum layer, and "steel plate" refers to a steel plate layer.

Next, the structures of the back plate 2 and the shelf boards 3 and 4 will be explained. FIG. 2(a) is an exploded side view of the back plate 2 (excluding the decorative sheet 50), and FIG. 2(b) is a sectional view of the back plate 2 taken along line AA in FIG. 1(a). 3(a) is an exploded side view of the lower shelf board 3 (excluding the decorative sheet 50), FIG. 3(b) is a sectional view of the shelf board 3 corresponding to the Ba-Ba line in FIG. 1(a), FIG. 3(c) is a schematic enlarged cross-sectional view commonly showing the layer structure of the Ca part in FIG. 2(b) and the Cb part in FIG. 3(b). FIG. 3(d) is a sectional view of the upper shelf board 4 corresponding to the line Bb-Bb in FIG. 1(a). 4(a) is a plan view of the ferromagnetic plate 18 included in the rear plate 2, and FIG. 4(b) is a plan view of the ferromagnetic plate 38 included in the lower shelf plate 3.

The plate-like parts 10, 30, 30A of the back plate 2 and the shelf boards 3, 4 are connected to a pair of substrate parts 11, 31 that face each other in the thickness direction, and a short plate surface of the plate-like parts 10, 30, 30A. A pair of thickness plate portions (end surface portions) 12 and 32 are provided that face each other in the hand direction. Here, the transversal direction of the plate surfaces of the plate-shaped parts 10, 30, and 30A is the vertical direction in the attached state for the rear plate 2, and the front-back direction in the attached state for the shelf board 3. The plate portions 10, 30, 30A have four peripheral walls formed by a pair of substrate portions 11, 31 and a pair of thickness plate portions 12, 32, and a hollow space is formed inside the four peripheral walls.

Each of the base plate parts 11 and 31 of the back plate 2 and the shelf boards 3 and 4 has a plurality of holes extending from one end in the longitudinal direction (width direction in the installed state) of the plate parts 10, 30, 30A to the other end. Ribs 14 and 34 are provided to face each other with a hollow space interposed therebetween. Furthermore, partition walls 15 and 35 (three for the rear plate 2 and one for the shelf plates 3 and 4) are provided to partition the hollow space. These ribs 14, 34 and partition walls 15, 35 ensure the strength of the hollow plate portions 10, 30, 30A.

As for the back plate 2, as shown in FIG. A protruding strip 13 is formed along the edge. In this way, the substrate portion 11 and the pair of protruding strips 13 constitute a recess 16 for accommodating the steel plate 18. Furthermore, a small groove 13a that is slightly recessed from the plate surface of the substrate portion 11 is formed at the inner corner of the substrate portion 11 and the protruding strip 13.

Further, L-shaped portions are formed protruding outward from the end surface portions 12 at the upper and lower ends of the plate-like portion 10 of the rear plate 2. A groove space 24 is formed by this L-shaped portion and the end surface portion 12. A concave groove body made up of the L-shaped portion and the end surface portion 12 serves as the fitting receiving portion 20 . In this way, the rear plate 2 has fitting receiving portions 20 for receiving the fitting convex portions 40 of the shelf boards 3 and 4 on the outside of each end surface portion 12 of both edges facing each other in one direction of the plate-like portion 10. are doing.

In other words, in the fitting receiving part 20, one groove wall is constituted by the end surface part 12 of the plate-like part 10, and the groove bottom is constituted by an extending plate part 21 extending outward from the rear plate surface of the plate-like part 10. The other groove wall is constituted by an upright plate portion 22 that stands up along the thickness direction of the plate portion 10 from the end of the extending plate portion 21.

Moreover, the upright plate part 22 has a upright plate main body 22a, and lid mounting pieces 22b are provided at both ends of the outer plate part 10 in the thickness direction (front-to-back direction in the attached state) of the upright plate main body 22a. It is formed integrally with the plate main body 22a. A locking groove 22c is formed between the lid attachment piece 22b and the upright plate main body 22a, and an opening 22d is formed between the pair of lid attachment pieces 22b. A blind cover 60 is secured to this cover attachment piece 22b. The locking structure and the detailed configuration of the blind cover 60 will be described later in the description of FIG. 5.

In this way, the back plate 2 has a back plate main body 2A including the plate-like portion 10 and a pair of fitting receiving portions 20 formed to be continuous with the plate-like portion 10. This back plate main body 2A may be integrally formed by extrusion molding.

Further, the upright plate main body 22a has a plurality of bolt insertion holes 23 along the longitudinal direction of the plate surface of the plate-like portion 10, and the extending plate portion 21 has a plurality of screw attachment holes 21a along the longitudinal direction. The end face portion 12 has a plurality of bolt attachment holes 12a along the same longitudinal direction. A threaded groove is formed in this bolt mounting hole 12a. Further, the diameter of the bolt insertion hole 23 is made larger than the diameter of the bolt head 7a (see FIG. 5).

Screws 6 (see Figure 5) are fixing devices for fixing the shelf (back plate 2) to the mounting base 5, and bolts 7 (see Figure 5) are for connecting the back plate 2 and shelf boards 3 and 4. It is a fixture. Therefore, the screw attachment hole 21a, the bolt insertion hole 23, and the bolt attachment hole 12a do not have to correspond in position, but the bolt insertion hole 23 and the bolt attachment hole 12a do correspond in position. Furthermore, the locations and number of fixing locations using the screws 6 and the locations and number of fixing locations using the bolts 7 are not limited to the example shown in FIG. 1, and may be provided as appropriate for the extrusion-molded back plate main body 2A.

A steel plate 18 is accommodated and pasted in the recess 16 of the rear plate main body 2A. The planar dimensions of the steel plate 18 are approximately the same as or slightly smaller than the bottom surface of the recess 16 (the surface of the substrate portion 11). The length of the steel plate 18 in the lateral direction of the plate surface of the plate-shaped portion 10 is set to a length that approximately closes the opening of the small groove 13a formed in the inner corner. By arranging the end of the steel plate 18 in the opening of the small groove 13a, lifting of the steel plate 18 after attachment is suppressed.

A decorative sheet 50 is attached to the plate-shaped portion 10 so as to cover the steel plate 18 disposed in the recess 16. The decorative sheet 50 is pasted on the exposed plate surface, and specifically, as shown in FIG. It is attached up to a portion of the opposite end surface portion 12 near the protruding strip 13. In addition, in FIG. 2(b), the decorative sheet 50 of the back plate 2 is shown by a two-dot chain line, but in other drawings, illustration of the decorative sheet 50 of the back plate 2 is omitted.

The dimensions of the rear plate 2 in the illustrated example are as follows.
Longitudinal dimension (width dimension): 900mm to 1000mm
Short dimension (vertical dimension) (including fitting receiving part 20): 250mm to 300mm
Projection dimension of fitting receiving part 20: (10mm to 15mm) x 2
Thickness of material such as board part: 1.5mm to 4.0mm (thickness varies depending on the part)
Thickness of plate-shaped portion 10: about 20 mm Of course, the size is not limited to this, and various sizes can be used.

As for the lower shelf board 3, as shown in FIGS. 3(a) and 3(b), one end in the thickness direction of the plate-like part 30 of the thickness plate part 32 (lower end in the attached state) has a base plate part. A protruding strip 33 slightly protruding from the surface of 31 is formed along the edge. The substrate portion 31 and the pair of protruding strips 33 constitute a recess 36 for accommodating the steel plate 38. Furthermore, a small groove 33a that is slightly recessed from the plate surface of the substrate portion 31 is formed at the corner between the substrate portion 31 and the protruding strip 33.

In addition, the shelf board 3 has a fitting receiving part 20 of the back plate 2 that protrudes from an end surface part 32 of one edge (rear end) of the plate part 30 so as to extend substantially parallel to the plate surface of the plate part 30. It has a fitting convex portion 40 that fits into the fitting convex portion 40 . The fitting convex portion 40 is a hollow convex strip, and its thickness is smaller than the thickness of the plate-like portion 30.

As described above, the shelf board 3 has the shelf main body 3A including the plate-like part 30 and the fitting convex part 40 formed so as to be continuous with the plate-like part 30. This shelf board main body 3A may be integrally formed by extrusion molding.

Further, the inner plate part 41 of the fitting convex part 40 (the plate part disposed on the upper side in FIG. 3(a)) has a plurality of bolt first insertion holes 42 along the longitudinal direction of the plate surface of the plate part 30. have. The outer plate part 43 (the plate part disposed on the lower side in FIG. 3(a)) connects a plurality of second bolt insertion holes 44 to the first bolt insertion holes 42 along the longitudinal direction of the plate surface of the plate part 30. It has a corresponding one. The diameter of the first bolt insertion hole 42 is made smaller than the diameter of the bolt head 7a, and the diameter of the second bolt insertion hole 44 is made larger than the diameter of the bolt head 7a. These insertion holes are provided at positions corresponding to the bolt insertion holes 23 of the rear plate 2 when the fitting convex portion 40 is attached to the fitting receiving portion 20.

A steel plate 38 is accommodated and attached to the recess 36 of the shelf body 3A. The planar dimensions of the steel plate 38 are approximately the same as or slightly smaller than the bottom surface of the recess 36 (the surface of the substrate portion 31). The length of the steel plate 38 in the lateral direction of the plate surface of the plate-shaped portion 30 is set to a length that approximately closes the opening of the small groove 33a formed in the inner corner. By arranging the end of the steel plate 38 in the opening of the small groove 33a, lifting of the steel plate 38 after attachment is suppressed.

A decorative sheet 50 is attached to the plate-shaped portion 30 so as to cover the steel plate 38 disposed in the recess 36. The decorative sheet 50 is attached mainly to the exposed plate surface, and specifically, as shown in FIG. 3(b), it is attached so as to wrap around the portion excluding the fitting convex portion 40. In addition, although the decorative sheet 50 of the shelf board 3 was shown by the two-dot chain line in FIG.3(b), illustration of the decorative sheet 50 of the shelf board 3 was abbreviate|omitted in other drawings.

The dimensions of the shelf board 3 in the illustrated example are as follows.
Longitudinal dimension (width dimension): 900mm to 1000mm
Short dimension (front and back dimension) (including fitting convex portion 40): 150mm to 200mm
Projection dimension of fitting convex portion 40: 10mm to 15mm
Thickness of material such as board part: 1.5mm to 4.0mm (thickness varies depending on the part)
Thickness of plate-shaped portion 10: about 20 mm Of course, the size is not limited to this, and various sizes can be used.

As described above, in both the rear plate 2 and the lower shelf plate 3, the plate surface of the plate portion 30 on which the ferromagnetic plates 18 and 38 are arranged has a ferromagnetic plate housed in the recess 36. A decorative sheet 50 is attached that hides the outer surfaces of the plate portions 18 and 38 and covers substantially the entire exposed surface of the plate portions 10 and 30.

FIG. 3(c) is a cross-sectional view showing the layer structure of the Cb portion of FIG. 3(b). Note that this figure is a schematic diagram in which the thickness of each layer is constant, and corresponds to Cb in FIG. 2B, the Ca portion in FIG. 2B also has a similar layer structure.

From the top of FIG. 3(c), aluminum serving as the base material of the substrate section 31 (aluminum layer), double-sided tape 51, steel plate 38 (steel plate layer), urethane resin adhesive 56, synthetic resin decorative sheet (olefin Sheets) are arranged in the order of 50.

The aluminum layer consists of an aluminum plate 31a and an alumite coating 31b disposed on the surface (lower surface) of the aluminum plate 31a. The steel plate layer 38 has a hot-dip galvanized steel plate 38d as a base material, an epoxy resin 52 is bonded to the top surface of the base material via an epoxy resin adhesive 53, and a polyester adhesive is bonded to the bottom surface of the base material. A polyester resin film 55 is adhered via an agent 54.

Electrolytic corrosion between the aluminum plate 31a and the hot-dip galvanized steel plate 38d is prevented by the alumite coating 31b, double-sided tape 51, epoxy resin 52, and epoxy resin adhesive 53 placed between the aluminum plate 31a and the hot-dip galvanized steel plate 38d. will be suppressed.

Note that the layer structure is not limited to the one described above, and it is sufficient that at least the substrate portion 31 made of a non-magnetic material and the ferromagnetic material plate 38 are arranged, and their coatings may be other materials, and they may be fixed together. An adhesive may be used instead of the double-sided tape 51. Further, other adhesives may be used in place of the adhesives described above.

Furthermore, although a wood grain or the like is preferably used as the decorative sheet 50, other patterns may be used, and furthermore, the decorative sheet 50 may not be pasted and the plate-shaped portion or steel plate may be exposed.

Note that illustration of a schematic cross section of a portion where the steel plate 38 is not provided is omitted. The area where only the decorative sheet 50 is arranged has a layered structure of an aluminum layer and the decorative sheet 50, and the area where neither the steel plate 38 nor the decorative sheet 50 is arranged has a layered structure of only an aluminum layer. Needless to say.

Moreover, since the steel plate 38 is not required for the upper shelf board 4, a plate-shaped portion 30A without the recess 36 (protruding strip 33) may be used, as shown in FIG. 3(d). The other parts of the plate-shaped part 30A and the fitting convex part 40 have substantially the same shape as the lower shelf board 3 and are vertically symmetrical, and each part is given the same reference numeral as the shelf board 3, and its shape is as follows. Explanation will be omitted. In the upper shelf board 4, the upper shelf main body 4A including the plate-shaped portion 30A and the fitting protrusion 40 may be formed by extrusion like the lower shelf main body 3A.

Further, a plate-like part 30 having a recess 36 may be used as the upper shelf board 4. In that case, a dummy material is placed in the recess 36 in place of the steel plate 38, and a decorative sheet 50 is pasted on it. Just put it on. It goes without saying that the fitting convex portion 40 of the upper shelf board 4 is provided in a vertically symmetrical shape with respect to the lower shelf board 3.

In this embodiment, the steel plates 18 and 38 accommodated in the recesses 16 and 36 have an elongated shape similar to the plate parts 10 and 30. 4(a) is a steel plate material 18A for the back plate 2, and FIG. 4(b) is a plan view of a steel plate material 38A for the shelf board 3. These are the attached steel plate materials 18A and 38A that are the basis of the steel plates 18 and 38, and by cutting them, they can be accommodated and pasted in the recesses 16 and 36.

The longitudinal direction of the steel plate materials 18A, 38A corresponds to the longitudinal direction of the plate parts 10, 30 (width direction in the attached state), and the steel plate materials 18a, 38a have a softer material than the steel plate materials 18a, 38a at both longitudinal ends of the steel plate materials 18a, 38a. The dummy aluminum plate materials 18b and 38b are made of a combined material. The steel plates 18, 38 to be attached to the plate-shaped parts 10, 30 are the remaining parts at the center of the dummy aluminum plates 18b at both ends of the steel plate materials 18A, 38A, after cutting out the outside of the dashed line in the figure. .

That is, at both ends of the ferromagnetic plates (steel plates) 18 and 38 in one direction, plates made of a material softer than the ferromagnetic plates (steel plates 18a and 38a) are coupled by two-color molding. In this way, the steel plates 18, 38 are fixed in the recesses 16, 36 as a steel plate mixed member with dummy plates 18c, 38c made of aluminum added to both ends.

The reason why the steel plates 18 and 38 (steel plate mixed member) are formed using such steel plate materials 18A and 38A is to avoid directly cutting hard steel plates that require an expensive cutter. If dummy aluminum plates 18b, 38b of predetermined dimensions are arranged at both ends of the steel plates 18a, 38a as shown in FIG. 4 so that the cutting position is the aluminum part, the steel plates 18a, 38b can be cut to the appropriate dimensions. It is not necessary to cut 38a. Therefore, only a cutter for aluminum can be used. Since the cutting position is within the range of the dummy aluminum plates 18b, 38b, it is possible to prevent the cutter from being damaged due to erroneously cutting the steel plates 18a, 38a.

Further, when the steel plate materials 18a and 38a are cut and removed, waste material containing a mixture of aluminum and steel is generated, but the above method of disposing of the generated waste material as only aluminum is considered to be a more appropriate method. Further, a member made of only the steel plate materials 18a, 38a having appropriate dimensions may be formed, but if the size is formed to be larger due to an error, cutting of the steel plate materials 18a, 38a is required. Therefore, this method of providing dummy aluminum plate materials 18b and 38b at both ends and cutting and removing a portion of the aluminum material is efficient and can reduce manufacturing costs.

As shown in FIGS. 4(a) and 4(b), a plurality of double-sided tapes 51 with release paper attached may be pasted over substantially the entire length of the steel plate materials 18A, 38A in the longitudinal direction. It is sufficient to cut the sheet with the release paper attached and peel off the release paper when pasting it to the recesses 16 and 36. Note that the double-sided tape 51 only needs to be attached so as to be able to adhere the substrate portion 31 and the steel plate 38, and for example, a plurality of double-sided tapes 51 may be attached across the width direction of the steel plate materials 18A and 38A.

Since the recesses 16 and 36 have protruding stripes 13 and 33 formed on opposing edges along the longitudinal direction of the substrate parts 11 and 31, alignment is easy when pasting the steel plate materials 18A and 38A.

Next, details of the connection structure between the back plate 2 and the shelf boards 3 and 4 will be explained with reference to FIGS. 5(a) and 5(b). In addition, FIG. 5 is an explanatory diagram of the connection structure between the back board 2 and the lower shelf board 3, and the connection structure between the back board 2 and the upper shelf board 4 is explained below. Since the connection structure is the same as that of No. 3, illustration thereof is omitted. FIG. 5(b) is an enlarged vertical cross-sectional view of the blindfold lid 60 shown in FIG. 5(a).

The fitting protrusion 40 of the shelf board 3 is attached to the groove space 24 (see FIG. 2) of the fitting receiving part 20 of the back plate 2. The bolt 7 is screwed into the bolt attachment hole 12a of the end face part 12 through the first bolt insertion hole 42 of the inner plate part 41 of the fitting convex part 40, and the back plate 2 and shelf board 3 are fixed. .

This bolt attachment operation involves passing the bolt 7 through the overlapping bolt insertion hole 23 of the upright plate portion 22 (erecting plate main body 22a) and the second bolt insertion hole 44 of the outer plate portion 43 of the fitting convex portion 40. It is done by As shown in FIG. 5, since the bolt head 7a is disposed when the bolt 7 is screwed and fixed, the bolt attachment operation is also performed within the hollow space of the fitting convex portion 40.

Note that as shown in FIG. 5(a), the screw attachment holes 21a provided in the extending plate portion 21 are closed due to the fitting between the fitting convex portion 40 and the fitting receiving portion 20, so that the rear plate 2 Before connecting the back plate 2 and the shelf board 3, it is necessary to fix the back plate 2 to the wall surface 5 with screws in advance.

Further, in order to support the shelf board 3 more firmly, it is preferable that the fixing portion by the bolt 7 (the bolt attachment hole 12a) be provided closer to the front side of the end face portion 12 of the back plate 2 as in this example. By arranging the bolt attachment hole 12a closer to the front side, the positions of the second bolt insertion hole 44 and the bolt insertion hole 23 are also the same as shown in the illustrated example. As a result, as shown in FIG. 5(a), the protrusion length of the upright plate portion 22 is larger than the thickness dimension of the plate-like portion 10, and the base of the outer plate portion 43 of the fitting convex portion 40 is 41 is located in front of the base.

With such a connection structure, the back plate 2 and the shelf boards 3 and 4 can be easily connected. Further, since the shelf boards 3 and 4 are hollow and made of aluminum, they are light and can be firmly fixed in a substantially horizontal state. Since the fitting protrusions 40, which are a part of the shelf boards 3 and 4, are sandwiched and supported by the fitting receiving parts 20 of the back plate 2, it is possible to suppress the shelf boards 3 and 4 from sagging.

In this way, since the connection structure between the back plate 2 and the shelf plates 3 and 4 is a fitting and bolted structure, and the plate material 1A is a hollow metal material that is light and strong, the shelf The shelves constructed by Unit 1 have superior load-bearing performance compared to those made of wood.

Regarding the shelf boards 3 and 4, a uniformly distributed load test was conducted on shelves 3 and 4 measuring 15 cm x 180 cm under the following conditions.
Load: 2.25 kg/100 cm ² (Approximately 61 kg (15 x 180/100 x 2.25 = 60.75) load was applied to the shelf board.)
Time: 168 hours During this test, no abnormalities such as falling, deformation, or rattling occurred.

Further, on the outside of the upright plate portion 22, there are provided a bolt insertion hole 23 of the upright plate main body 22a, a second bolt insertion hole 44 of the fitting convex portion 40, and a bolt of the bolt 7 in the installed state located above these insertion holes. A blindfold lid 60 is attached to hide the head 7a. The blind cover 60 is also attached to the connecting portion between the back plate 2 and the upper shelf board 4.

The blind cover 60 is a band-shaped synthetic resin member, and may be made by two-color molding, for example, an ABS resin material 60A and an AES resin material 60B on the surface side. For example, a material whose surface has a pattern that matches the pattern of the decorative sheet 50 attached to the plate-shaped portion 10 may be used.

The longitudinal dimension of the blind cover 60 is approximately the same as the longitudinal dimension of the plate surface of the plate portion 10 of the back plate 2. As shown in FIG. 5(b), the blindfold lid 60 includes a flat blindfold lid main body 61, and a blindfold lid attachment part 62 made up of two leg pieces 62a extending along the longitudinal direction of the blindfold lid main body 61. It is equipped with A locking projection 62b having a guide surface 62c is provided at the tip of the leg piece 62a. The dimension between the outer surfaces of the two leg pieces 62a substantially matches the width dimension of the opening 22d between the lid attachment pieces 22b of the upright plate portion 22.

The blindfold lid 60 is constructed by sliding the guide surface 62c of the leg piece 62a on the tip of the lid attachment piece 22b and pushing the leg piece 62a toward the plate part 10 while bending the leg piece 62a, so that the locking protrusion 62b is attached to the upright plate part 22. It is locked in the locking groove 22c and attached to the upright plate part 22. In addition, in the blind cover 60 shown in the figure, the guide surface 62c of the locking protrusion 62b is formed into a mountain shape so that it can be installed and removed without being completely fitted, in consideration of readjustment of bolt fixing. There is.

According to such a blind cover 60, it is possible to hide the bolt heads 7a, insertion holes, etc. exposed to the outside in the connection structure between the back plate 2 and the shelf boards 3 and 4, and the surface thereof can be adapted to the design of the decorative sheet 50. By combining them, you can enhance the design. It can also prevent dust from entering.

The connection structure between the back plate 2 and the shelf plates 3 and 4 may be as shown in FIG. The illustration of the upper shelf board 4 is omitted. In this example, the second bolt insertion hole 44 provided in the outer plate part 43 of the fitting convex part 40 of the shelf board 3 is different from the one in FIG. It's sato. That is, when the bolt 7 is screwed in, the bolt head 7a of the bolt 7 is placed outside the outer plate part 43, that is, in the bolt insertion hole 23 of the upright plate part 22, as shown in FIG. be done.

The example shown in FIG. 6 has the advantage that the screwing operation of the bolt 7 is facilitated. On the other hand, it is necessary to use longer bolts 7 as shown in the figure, and there is a possibility that the leg piece 62a comes into contact with the bolt head 7a when attaching the blind cover 60, compared to the one shown in FIG. 5(a). It may become difficult to install.

Next, the side lids 70A and 70B that close the side openings of the plate-shaped parts 10, 30, and 30A will be described with reference to FIG. FIG. 7(a) is a perspective view of a side lid 70A for the back plate 2, and FIG. 7(b) is a perspective view of a side lid 70B for the shelf boards 3 and 4. FIG. 7(c) is a perspective view showing how to attach the side lid 70B for shelf boards 3 and 4 using an example of the lower shelf board 3, and FIG. 7(d) is a perspective view taken along the line DD in FIG. 7(c). It is an arrow sectional view.

Both side lids 70A and 70B are members made of synthetic resin such as ABS resin, and include a side lid main body 71 and a side lid mounting portion 72. A decorative sheet (not shown) is adhered to the surface of the side lid main body 71 by TOM molding.

The side lid mounting part 72 has a hollow structure with an open end and a space surrounded by a mounting part main body 73 having four peripheral walls and a side lid main body 71. In the side lid 70A for the back plate 2, the side lid mounting portions 72 are separated into four parts in the longitudinal direction (see FIG. 7(a)). In the side lid 70B for the shelf board 3, the side lid mounting portion 72 is separated into two in the longitudinal direction, one of which is provided with a partition wall midway in the longitudinal direction (see FIG. 7(b)). . The wall thickness of the mounting portion main body 73 becomes thinner toward the tip, and the mounting portion main body 73 has a slightly concave shape as a whole (see FIG. 7(d)).

Further, on the outer wall surface of the mounting portion main body 73, a press-contact convex portion 74 that slightly protrudes from the wall surface is formed from the base of the wall to the tip. A plurality of pressing convex portions 74 are provided along the circumferential direction of the side lid mounting portion 72 at predetermined intervals. The pressing convex portion 74 has a guide surface 74a with a downwardly inclined tip side (see FIG. 7(d)). In other words, both the mounting portion main body 73 and the pressing convex portion 74 are shaped to have a guiding function.

As shown in FIG. 7(c), the side lid 70B is attached to the hollow space of the plate-like part 30 while the pressure-contact convex part 74 is pressed by the rib 34 of the plate-like part 30. As shown in FIG. Note that since it is not necessary to remove the side lid 70B after constructing the shelf, an adhesive may be applied to the surface of the press-contact convex portion 74 to fix it.

According to such side lids 70A and 70B, the side openings of the back plate 2 and shelf boards 3 and 4 formed by extrusion molding can be closed and the hollow spaces can be hidden. By attaching a sheet with a design to the surfaces of the side lids 70A and 70B, the design can be enhanced. It can also prevent dust from entering.

Since the shelf unit 1 is thus provided with the side lids 70A, 70B and the aforementioned blind lid 60, it is possible to suppress deterioration in aesthetic appearance due to not having side plates. Rather, by not including side plates, a shelf with a neat appearance can be created.

Next, a method for installing the shelf unit 1 as a shelf will be described with reference to FIGS. 8(a) and 8(b). Incidentally, the side lids 70A, 70B may be attached to the plate portions 10, 30, 30A in advance.

First, the back plate 2 is fixed to the mounting base 5 such as a wall surface with screws 6 ((1) in FIG. 8(a)).
Next, attach the fitting protrusions 40 of the shelf boards 3 and 4 to the fitting receiving parts 20 of the back plate 2 ((2) in FIG. 8(b)), and fix them with the bolts 7 (see FIG. 8(b)). (3)).
Finally, a blind cover 60 is attached to hide and close the connecting parts (bolt heads, etc.) between the back plate 2 and the shelf boards 3 and 4 ((4) in FIG. 8(b)).

By using the shelf unit 1 as described above, shelves can be easily installed on a wall surface of a kitchen or the like. Note that the locations and number of fixing locations using the screws 6 and the locations and number of locations connected using the bolts 7 are not limited to those shown in the figures. In this embodiment, as shown in FIG. 8, there are screws 6 in 6 locations, 3 on the top and 3 on the top (maximum 7 locations, 14 locations in total). There are seven bolts 7 for each shelf board 3 and 4.

The main body parts of the back plate 2, shelf boards 3, and 4 used in such a shelf unit 1 (excluding the fitting receiving part 20 and the fitting convex part 40) can be replaced with the panel P described below. You can also do it.

That is, the panel P has a hollow plate-shaped portion that is substantially rectangular in plan view and is made of a non-magnetic material as a base material. Recesses 16 and 36 are formed in at least one plate surface of the hollow plate-shaped portion, and ferromagnetic plates 18 and 38 are accommodated and fixed in the recesses 16 and 36, and at least the outer surface of the ferromagnetic plates 18 and 38 are A decorative sheet 50 is attached that hides and covers substantially the entire surface of the hollow plate-shaped portion.

This hollow plate-shaped portion has a generally similar configuration to the plate-shaped portions 10 and 30 shown in FIGS. 2 and 3. That is, when using the panel P for installing a shelf similar to that shown in FIG. You may make it connect panels P by structure. Moreover, this type of panel P can also be used as other interior materials. For example, the panel P may be used for furniture, or may be used in place of some wall materials.

Note that although the illustration of the panel P is omitted, the reference numeral of the panel P is given in FIG. 2(a) and FIGS. 3(a) and (d) instead.
