Next, a shelf plate and a manufacturing method thereof according to a first embodiment of the present invention will be described with reference to Figs. 1 to 11. Fig. The shelf plate 10 is composed of a box body 20 having a top plate 1, a bottom plate 2 and a side plate 3 and an integral body of the foamed body Y filled in the hollow portion X of the box body 20 It is water. The box body 20 is a member that covers the outer side of the foamed material Y which is the core material. In this example, the shelf plate 10 is substantially rectangular in plan view, and four corners are round (R). As a result, it is suitable for multi-stage display, and it is also possible to prevent scratches by customers. The corners 7 of the four corners may be made of a material different from that of the box body 20, for example, resin. In this case, the corner member 7 is fitted into the cut edge of the box body 20. When the shelf plate 10 is a polygon having a hexagonal or more shape, the round (R) shape may be omitted.

As the box body 20, a metal plate such as a steel plate, an aluminum plate, or a stainless steel plate, or a non-metallic plate such as a resin plate containing reinforcing fibers may be used. Of these, a metal plate such as a steel plate having a thickness of 0.25 to 0.35 mm is preferable in that it is lightweight, has high strength, and can be bonded to a foam as a core member to be integrated.

In the shelf plate 10, the box body 20 may be of a container type in which the top plate 1, the bottom plate 2 and the side plate 3 are integrally formed, or a plurality of members may be fitted. In this example, the box body 20 has a cover-like upper member 1A having a top opening 1 and a top side plate 3, and a bottom plate 2 and a bottom side plate 4 Shaped lower member 1B that is opened upward. The upper side plate 3 and the lower side plate 4 all have four side plates of the left and right side plates and the front and rear side plates. That is, the number of vertical and horizontal positions of the upper member 1A is substantially the same as the outer dimension of the vertical and horizontal lengths and the height of the lower member 1B (see FIG. 5). The fitting body of the upper member 1A and the lower member 1B has a structure in which the upper member 1A covers the entire lower member 1B excluding the lower plate 2. [ The fitting of the upper member 1A and the lower member 1B does not particularly require a coupling portion and only the lower member 1B may be provided so that the upper member 1A substantially covers the gap. The upper member 1A and the lower member 1B are preferably formed by sheet metal working.

The form of contact between the side plates of the upper member 1A and the lower member 1B is not particularly limited. For example, as shown in Figs. 6 and 7, an upper side plate or an upper side plate serving as an outer peripheral portion of the fitting body It is preferable that the front end in the width direction of the lower side plate is folded inwardly and the front end appearing in the outer side is rounded. 6 shows that the distal end 311 in the width direction of the side plate 31a of the upper member 1A is a folded folded portion and the distal end 311 appearing on the outside is rounded. Therefore, the hand of the customer who holds the product is not damaged. 7, the distal end portion 321 in the width direction of the side plate 32a of the upper member 1A is a folded folded portion, and the distal end 321 appearing on the outer side is rounded. Therefore, the hand of the customer who holds the product is not damaged. 6 is different from the side plate 31a of Fig. 6 in that the side plate of the lower member 1B has a small height and the other side of the side plate 31a of the upper member 1A The height of the inner plate is small. 6 and 7, the upper member 1A may be a lower member and the lower member 1B may be an upper member in a state of being flipped upside down. In this case, the rounded portion of the bent portion appearing on the outer side becomes the upper end (tip end).

The box body 20 is not limited to the ones shown in Figs. 1 and 2, and examples of the outer shape of the box body include a circular, oval, polygonal shape other than a quadrangle, and an irregular shape when viewed in plan view. That is, the side plate of the present invention means a circular side plate (circumferential side plate), an elliptical side plate, a polygonal side plate, and an irregular side plate.

The surface of the foam material Y which is a core material and the inner circumferential surface of the box body 20 are bonded or welded (hereinafter, simply referred to as " adhesion "). That is, the foam (Y) is foamed and hardened inside the box body (20) by injecting the foamed stock solution from the outside, and there is no internal gap. Therefore, the present invention is different from a shelf plate in which a foam having a predetermined shape is produced in advance, and a top plate, a bottom plate and a side plate are attached to the foam using an adhesive or double-sided tape. That is, the shelf plate 10 of the present invention can omit the adhesive and the double-sided tape, and can firmly integrate the box body and the foam.

Examples of the foams include synthetic resin foams such as polyurethane foam, polyisocyanate foam, polystyrene foam, phenol foam and polyethylene foam. For example, a foaming stock solution containing a stock solution, a curing agent and a foaming agent is prepared, And discharging it into the box body 20, and reacting, foaming and curing in the box body 20. Among the above-mentioned foams, rigid or semi-rigid polyurethane foam, polyisocyanate foam, and polystyrene foam are preferable, and rigid or semi-rigid polyurethane foam is particularly preferable.

The leg portions 62a, 62b and 62c of the fall preventing portion 6 are engaged with each other at a predetermined pitch in the longitudinal direction near the end of the top plate 1, The engagement holes 8a, 8b and 8c are formed. As a result, it is possible to freely install and separate the fall preventing portion 6. In addition, the installation of the fall preventing portion 6 is stabilized. In addition, the shelf board 10 is provided with a fall preventing portion 6. Thus, for example, when the shelf plate of the front downward inclination is used, the display product is prevented from falling forward. When the fall preventing portions 6 are provided on the shelf plate 10, the leg portions 62a to 62c of the fall preventing portions 6 are fitted into the engaging holes 8a, 8b and 8c of the shelf plate 10 do.

In the shelf plate 10, the box body 20 is provided with a foaming stock solution inlet 5, and the injection port 5 is covered with a cover material 50 (see FIGS. 2 and 11). The foamed stock solution inlet 5 is a hole into which the tip of the nozzle of the foamed stock solution injecting mechanism (not shown) is fitted. The foamed raw liquid injection port 5 may be formed at any position among the top plate 1, the bottom plate 2 and the side plate 3 of the box body 20. In this example, the two side plates 3a, 3a. When the box body 20 is a fitting between the upper member 1A and the lower member 1B, the injection port 5 is formed at the corresponding position of the upper member 1A and the lower member 1B, respectively. Thus, the injection port 5 is formed in the fitting body of the upper member 1A and the lower member 1B. The cover material 50 may be any material that covers the injection port 5, and may be a makeup sealer to which an adhesive is applied to the adhesive surface.

In the shelf board 10 of the present invention, the form of contact between the side plates of the upper member 1A and the lower member 1B is not particularly limited and, for example, as shown in Fig. 8 Likewise, the tip end side of the side plate 33a of the upper member 1A is curved inward in the lateral direction from the center in the height direction to form a step. In the bent tip end portion, the side plate 33a of the lower member 1B 42a. Also in the side plate shape of Fig. 8, the edge of the side plate does not protrude outward, and the hand of the customer who holds the product is not damaged. In addition, as shown in Fig. 10, the horizontal portion 322 may be formed by bending the tip end portion of the folded bent portion of the side plate 32a of the upper member 1A further inward as shown in Fig. At this time, the tip end of the side plate 42a of the lower member 1B is in contact with the back surface of the horizontal portion 322. Thus, only the upper member 1A is covered with the lower member 1B, whereby the positions of both members are determined. Figs. 5 to 8 show the state before the stock solution is injected, and Fig. 10 shows a state in which the foamed material is foamed and cured in the box body after the stock solution is injected.

According to the shelf plate 10 of the present invention, the inner circumferential surface of the box body 20 and the outer circumferential surface of the foam material Y are bonded. The inner circumferential surface of the box body 20 and the outer circumferential surface of the foam material Y are in contact with each other without gaps. Therefore, both members do not generate a gap and act as an integral body with respect to the bending force. Because of this, it is lightweight and has high strength. Further, since there is no use of an adhesive or the like, the number of parts is small, and the core material is not substantially exposed, it is excellent in designability and does not deteriorate display effect of display. In addition, the surface of the shelf board 10 on which the product is placed can have a soft cushion and a soft display surface that does not damage the product.

Next, a method of manufacturing the shelf plate of the present invention will be described. A method of manufacturing a shelf plate of the present invention includes a step of injecting a foaming stock solution from a foaming stock solution inlet formed in a box body having a top plate, a bottom plate, and a side plate into a box body and curing the foaming stock solution in the box body.

In the manufacturing method of the present invention, the box body 20 having the top plate, the bottom plate and the side plate is an intermediate body. Examples of the box body 20 include a metal plate such as a steel plate, an aluminum plate, and a stainless steel plate, or a non-metallic plate such as a resin plate containing reinforcing fibers. Of these, a metal plate such as a steel plate having a thickness of 0.25 to 0.35 mm is preferable in that it is lightweight, has high strength, and can be bonded to a foam as a core member to be integrated.

In the case of the shelf board 10, the box body 20 may be of a container type in which a top plate, a bottom plate and a side plate are integrated, or a plurality of members may be fitted. The box body 20 includes a top member 1A in the form of a lid having a top opening 1 and a top side plate 3 and a bottom plate 2 and a bottom side plate 4, Shaped lower member 1B that is opened upward. The fitting body of the upper member 1A and the lower member 1B has a structure in which the upper member 1A covers the entire lower member 1B excluding the bottom plate 2. [ The fitting of the upper member 1A and the lower member 1B does not particularly require a coupling portion and only the lower member 1B may be provided so that the upper member 1A substantially covers the gap. The upper member 1A and the lower member 1B are preferably formed by sheet metal working. Hereinafter, a manufacturing method using the upper member 1A and the lower member 1B will be described.

As shown in Fig. 2, cutouts 711 and 712 are formed at four corners of the upper member 1A and the lower member 1B, respectively, in which the corner member 7 is fitted. Through holes 91a, 91b, and 91c through which the fall preventing portion support members 9a, 9b, and 9c are fitted are formed at predetermined positions of the lower member 1B. The engaging holes 8a, 8b and 8c are formed at a predetermined pitch in the longitudinal direction near the end of the top plate 1 of the upper member 1A, that is, in the width direction in this example. A foaming stock solution inlet 5 is formed in the side plates 3a and 4a of the upper member 1A and the lower member 1B, respectively.

Prior to manufacturing, the fall preventing portion receiving members 9a, 9b, and 9c and the corner members 7a to 7d are prepared in addition to the upper member 1A and the lower member 1B. The fall preventing portion restraining member 9 is disposed in the box body 20 to fix the fall preventing portion 6. A coupling longitudinal hole 94 is formed in the upper center of the substantially columnar body, A protruding portion 92 extending downward is formed. The leg portion 62 of the fall preventing portion 6 is fitted into the engaging longitudinal hole 94 and the projecting portion 92 is fitted into the through hole 91 of the bottom plate 2. [ The protrusion length of the protruding portion 92 corresponds to the thickness of the bottom plate 2 and is not shown in Fig. 4 because it is short. 3, the corner member 7 is substantially L-shaped in plan view and the corner portion 701 is a rounded shape, and each of the upper and lower members 1A and 1B And the corner portion has a round (R) shape and has a shape corresponding to the corner portion of the box body. The plate-like engaging pieces 702 and 703 extending from the corner portion 701 to both sides abut on the inner surfaces of the side plates of the upper member 1A or the lower member 1B. Even if the volume of the foamed body is increased by the reaction in the box body 20, the plate-like engaging pieces 702 and 703 serve as stoppers, It does not come off from the notch 7 at the corner.

First, the lower member 1B is installed on the work table with the bottom plate 2 downward. Next, the protruding portions 92 of the fall preventing portion supporting members 9a, 9b and 9c are fitted into the through holes 91a, 91b and 91c, respectively, and the fall preventing portion supporting members 9a, 9b and 9c are inserted into the bottom plate 2). The engagement between the protruding portion 92 of the fall preventing portion restraining members 9a, 9b and 9c and the through holes 91a, 91b and 91c may be such a coupling as not to move when the undiluted foamed liquid reacts. The projecting portion 92 does not protrude downward from the lower surface of the bottom plate 2. The corner member 7 is fitted into the notches 712 at the four corners of the lower member 1B from the inside toward the outside (Figs. 3 (A) and 3 (B)). Next, the upper member 1A is sandwiched so as to cover the lower member 1B with the top plate 1 facing upward (see Fig. 2). That is, the lower member 1B and the upper member 1A are fitted to each other. Thus, the box body 20 having a hollow portion can be formed. At this time, the engagement longitudinal holes 91 of the fall preventing portion restraining members 9a, 9b and 9c correspond to the engagement holes 8a, 8b and 8c of the upper member 1A, respectively. In addition, corner members 7 are located at four corners of the box body 20.

Next, as shown in Fig. 9, the box body 20, which is an intermediate body, is fixed with the fixing jig 150 so as to restrict the movement in the thickness direction. The fixing jig 150 is composed of an upper member placed on the top plate 1 and a lower member placed under the bottom plate 2 with a connecting member such as a bolt. In this embodiment, a plurality of long plates are used, but they may be sandwiched between a pair of plates larger than the top plate 1 and the bottom plate 2. [ Thus, the shape of the box body 20 of the intermediate body can be maintained even when the raw foaming fluid is injected into the box body 20 from the outside and reacted in the box body 20.

Next, a raw foaming liquid is injected into the box body from the foaming raw liquid inlet 5 formed in the box body 20, and the step of curing the foaming raw liquid in the box body is performed. As the foaming stock solution, a synthetic resin foam such as a polyurethane foam, a polyisocyanate foam, a polystyrene foam, a phenol foam, or a polyethylene foam is formed after the reaction, and it may be a stock solution containing a known raw solution, a curing agent and a foaming agent. For example, in the case of a polyurethane foam, a polyol mixture containing an polyol component, an amine compound, water and a catalyst, and an isocyanate component are mixed and stirred, and the obtained mixture is injected from an injection port 5 , Injected into the box body 20, and reacted, foamed and cured in the box body 20 (see FIG. 9).

The foamed raw liquid is foamed and hardened in the box body 20 to be foamed (Y). At this time, the three fall preventive restraining members 9a, 9b and 9c are fixed to the bottom plate 2, and the fixing position is not slipped by the infusion of the foamed stock solution. Although the four corner members 7a to 7d are rounded out from the cutouts 711 and 712, the engaging pieces 702 and 703 are provided on the side plates of the upper member 1A or the lower member 1B. It is installed in the cutouts 711 and 712 without gaps and is not removed. As described above, the surface of the foamed material Y, which is the core, and the inner circumferential surface of the box body 20 are in contact with each other or in close contact with each other in the box body 20, and both are free from internal gaps and become integral bodies.

Next, it is preferable to cover all outer peripheral surfaces of the box body 20 except for the corner members 7a to 7d and the engaging holes 8a, 8b, 8c with a decorative sheet. It is preferable that the foamed raw liquid injection port 5 formed in the box body 20 is covered with the cover material, in this example, the seal paper 50. Thereby, the shelf plate 10 having the foam (Y) as a core material is obtained. The shelf board 10 is provided with a fall preventing portion 6 as necessary. The fall preventing portion 6 can be provided by fixing the leg portions 62a, 62b, 62c of the fall preventing portion 6 to the engaging holes 8a, 8b, 8c. Accordingly, when the shelf plate 10 is installed as the front downward inclination, it is possible to prevent the article from falling forward.

Next, the shelf board 10a according to the second embodiment of the present invention will be described with reference to Figs. 12 to 14. Fig. In Figs. 12 to 14, the same constituent elements as those in Figs. 1 to 11 are denoted by the same reference numerals, and a description thereof will be omitted, and the difference will be mainly described. That is, in the shelf plate 10a shown in Figs. 12 to 14, the box body 20a is different from the shelf plate 10 shown in Figs. 1 to 11 in that the box body 20a is provided on the left and right side plates of the box body 20, The corner plate of the shelf plate 1a is not provided with a rounded shape and the shelf plate 1a is provided with the fall preventing portion restraining members 9a, 9b, 8b and 8c in which the through holes 91a, 91b and 91c in which the leg portions 62a, 62b and 62c of the fall preventing portion 6 are fitted are not formed, and And the second left and right side plates 17 and 17 are formed on the left and right side plates of the box body 10a.

That is, the shelf plate 10a includes a box body 20a having a top plate 1a, a bottom plate 2a, left and right side plates 3a 'and front and rear side plates 3b' And the second left and right side plates 17 and 17 having the foamed stock solution inlet 5 '(second foamed stock solution inlet) are formed in the left and right side plates 3a' and 3a ' ).

As shown in Fig. 14, the second left and right side plates 17 and 17 of the shelf plate 10a have a plate shape having a predetermined thickness corresponding to the shapes of the left and right side plates 3a 'and 3a' of the box body 20a As the upper body, a plurality of engaging holes 11 of the left and right side plates 3a ', 3a' of the box body 20a are formed on the surface (back surface) of the box body 20a on the left and right side plates 3a ' A concave groove 172 having a rectangular cross section is formed on the surface (surface) opposite to the left and right side plates 3a 'and 3a' of the box body 20a, leaving both end edges and the upper edge, Is formed.

The engaging projection 171 is inserted into the engaging hole 11 or enters the engaging hole 11 by press fitting. The length of the coupling projection 171 is larger than the plate thickness of the left and right side plates 3a ', 3a' of the box body 20a. Therefore, the front end of the engaging projection 171 adheres to the foam, and the left and right side plates 3a ', 3a' are firmly fixed to the box body 20a. The concave groove 172 is engaged with the rising wall 61 of the receiving member 60 of the L-shaped cross section corresponding to both right and left arms of the fixed side support frame, for example. That is, the recessed groove 172 is a shape in which the rising wall 61 of the receiving member 60 is fitted. Thus, the shelf plate 10a can be simply installed on the support frame of the merchandise display shelf called the gondola having the support member 60, from above.

Next, a method of manufacturing the shelf plate 10a will be described. First, a box body 20a as an intermediate body is fabricated (Fig. 13). The manufacturing method of the box body 20a is the same as the manufacturing method of the box body 20. That is, the box body 20a may be of a container type in which the top plate 1a, the bottom plate 2a 'and the side plates 3a', 3b 'are integrally formed, or a plurality of members may be fitted. Like the box body 20, it may be a fitting body of a box-shaped lower member including a top member having a top opening and a bottom plate having a top plate and an upper side plate, and a bottom plate and a bottom side plate. A plurality of fitting holes 11 to which the engaging projections 171 are engaged are formed at the appropriate intervals in the left and right side plates 3a 'and 3a' of the box body 20a, Respectively.

Next, the second left and right side plates 17, 17 are mounted on the left and right side plates 3a ', 3a' of the box body 20a. That is, the engaging protrusions 171 of the second left and right side plates 17 and 17 are inserted or press-fitted into the engaging holes 11 of the left and right side plates 3a 'and 3a' of the box body 20a. At this time, the foamed stock solution injection port 5 of the left and right side plates 3a 'and 3a' of the box body 20a coincides with the foamed raw solution injection port 5 'of the second left and right side plates 17 and 17, Thereby forming a through hole.

Next, in the same manner as in the manufacturing method of the box body 20, the box body 20a as the intermediate body is fixed with the fixing jig so as to regulate the movement in the thickness direction. Next, the raw foaming liquid is injected into the box body 20a from the raw foaming liquid inlet 5 'of the second left and right side plates 17, 17, and the step of reacting and curing the foaming raw liquid in the box body is performed. After the reaction and curing in the box body 20a, the foamed raw liquid becomes the foam (Y). At this time, the engaging protrusions 171 of the second left and right side plates 17, 17 protrude into the box body 20a, and when they are cured, they adhere to the foam body and are integrated. Thus, the second left and right side plates 17 and 17 are fixed to the box body 20a. The surface of the foamed product Y as a core and the inner circumferential surface of the box body 20a are in contact with or in close contact with each other and there is no internal gap and the box body container and the foamy body Y It becomes one.

The article display apparatus of the present invention is provided with the shelf plate of the present invention, and is preferably supported on the support frame so as not to be rotatable or rotatable. The shelf plate may be single-stage or multi-stage up and down. For example, in the article display apparatus 30 of Fig. 15, the shelf plate 10 is freely installed on the support frame 40 in the upper and lower four stages in the pivot range of 0 to 90 degrees in the vertical direction. That is, the support frame 40 includes two legs 421 and 421 separated from the leg 41 by a predetermined distance, and an upper crossbar member 422 laid between the legs 421 and 421 And a frame main body portion 42 which is formed with a plurality of support posts 42. The shelf plate 10 is provided in multiple stages between two support posts 421 and 421.
