Description

FIELD OF THE INVENTION

The present invention relates to an article (article for sale) display and take-out unit structured so as to display articles such as canned goods, bottled goods, paper bagged goods, boxed goods and the like in line, and take out the goods in the foremost portion of the display, and an article display rack using the unit.

RELATED ART

Conventionally, in a general merchandising store such as a supermarket, a drag store or the like, many kinds of articles are abundantly displayed in individual display racks in an article display case 50 shown in FIG. 12 (Japanese Patent Application Laid-open No. Hei-8-24091). Since the articles are sold from the front side, the front portion necessarily gets into an emptied state. Accordingly, a so-called forward feeding work for feeding the articles at the back to the front side is necessary. Therefore, there have been proposed a lot of article display racks and article display devices which are provided with various automatic or semiautomatic forward feeding functions.
An article take-out unit 51 provided with a conventional forward feeding function is provided fixedly with both side plates 52 a and 52 b having a function of comparting the articles. Accordingly, it is possible to display articles 53 having a size or dimension matching to a width formed by both the side plates 52 a and 52 b, however, an additional unit matching thereto is necessary for displaying the articles which are larger than the width. Accordingly, in a general merchandizing store or the like, it is necessary to prepare many kinds of display and take-out units, and there is such a problem that a stock control or the like is troublesome. Further, in order to freely adjust a compartment width of the articles, there is a display rack which is provided with a detachable article compartment plate. However, in this display rack, it is not possible to securely prevent a side skid of heavy articles such as drink bottles or the like. Further, a hanging error of the article compartment plate is apt to be generated, and there is accordingly generated such a problem that an appearance is bad or the like.
In order to solve the problem mentioned above, an article display and take-out unit 60 as shown in FIGS. 13 and 14 has been developed (Japanese Patent No. 3126947). This is constructed by a unit main body 61, an article compartment plate 62, and an article forward slant prevention plate 63. The unit main body 61 is constructed by a shallow box-shaped frame body portion 69 which is comparted into three sections in its center portion, a front engagement hole 64 which is perforated in a front engagement hole portion, a rear engagement hole 65 which is perforated in a rear engagement hole portion, and an article forward slant prevention plate support portion 67 which forms an engagement groove 66 with respect to a front end of the front engagement hole portion, and is formed as an approximately rectangular shape made of a resin as a whole. Further, as shown in FIG. 14, three roller arrangement frame bodies 70 are fitted respectively in the sections of the shallow box-shaped frame body portion 69 in the center portion, the roller arrangement frame bodies 70 being provided with a lot of rollers R which are provided rotatably in such a manner as to slide the articles 53 forward. The roller arrangement frame body 70 is a shallow box-shaped member having five rows of roller arrangement portions. Further, each of the rollers R having a shaft insertion hole in its center is pivotably attached to both side wall plates 71 of the roller arrangement frame body 70 and a shaft 72 which is supported by a shaft hole formed in a roller guide wall plate 68. Each of the rollers R is attached in such a manner that a top portion projects above the top portions of the roller guide wall plate 68 and an article stabilization auxiliary plate 73 upward at about 0.3 mm. The roller guide wall plate 68 has a function of a stabilization correction plate by which the articles slide stably. The front engagement holes 64 and the rear engagement holes 65 are formed three rows per one line, and are formed in accordance with a zigzag pattern in which a position of the hole is not placed on the same level laterally with the positions of the adjacent holes in both sides. A hole shape of the engagement hole 64 is a rectangular shape which is somewhat larger than a cross sectional shape of the front engagement portion 62A of the article compartment plate 62. Further, the rear engagement hole 65 has the same structure.
A prior art (cf. Japanese Patent No. 3126947) shown in FIGS. 13 and 14 is an article display and take-out unit 60 which has a bottom surface portion that slides the articles 53 forward, a front engagement hole portion that has in a lateral direction a lot of front engagement holes 64 with which the front engagement portion 62A of the article compartment plate 62 is detachably engaged, and a rear engagement hole portion that has in a lateral direction a lot of rear engagement holes 65 with which the rear engagement portion 62B of the article compartment plate 62 is detachably engaged, and is installed to be oriented inclining downwardly toward the front side. Further, the engagement holes 64 and 65, which are formed in the front engagement hole portion and the rear engagement hole portion, are of a rectangular shape, and are provided so as to prevent a hanging error of the article compartment plate 62, by preventing the positions of the engagement holes formed in the front engagement hole portion and the rear engagement hole portion from being placed on the same level laterally with the positions of the adjacent engagement holes in both sides. In accordance with this structure, it is possible to securely ensure a display position of heavy articles such as the drinking bottles or the like, and it is possible to prevent the hanging error of the article compartment plate. Further, since the article display unit can be applied to every modes of articles, it has such an advantage that a stock control can be easily achieved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

A description will be given below of an embodiment in accordance with the present invention with reference to the accompanying drawings.
FIG. 1 is a perspective view before an assembly for integrally mounting an article support member 3 and a rigid plate 4 on a shelf plate 2 of an article display rack 1. The article support member 3 is structured so that rollers 6, which support the articles vertically to a moving direction of the articles, are rotatably installed in parallel in a main body base 5. It is preferable that the main body base 5 and the rollers 6 are formed by a synthetic resin material. Further, the rigid plate 4 is provided on a lower surface of the main body base 5 of the article support member 3; is structured so that its upper surface keeps a horizontality; and is provided for preventing a distortion of the article support member 3 from being generated by a weight of the articles. The rigid plate 4 retains a rigidity while achieving a weight saving, for example, by using an aluminum plate, thereby making the article support member 3 hard to be distorted by the weight of the articles.
Integration of the article support member 3 and the rigid plate 4 can be achieved by using and assembling a first attachment 7 and a second attachment 8. The first attachment 7 has a main body portion 7B that has a back face forming a groove 7A and a front face forming an upper stage insertion port 7C to which a front portion 3A of the article support member 3 is inserted, and a lower stage insertion port 7D to which a front portion of the rigid plate 4 is inserted. The second attachment 8 has an insertion port 8A to which only a rear portion of the rigid plate 4 is inserted. A main body portion 8B of the second attachment 8 is of a hollow elongated square pole shape, and has a pair of parallel rib-shaped portions 8C provided so as to project from one side surface of the main body portion 8B, thereby forming the insertion port 8A between the rib-shaped portions 8C.
FIG. 2 is a side elevational schematic view just before the article support member 3 and the rigid plate 4 are integrally assembled. The first attachment 7 and the second attachment 8 are directly mounted on the shelf plate 2, and front and rear portions of the rigid plate 4 are inserted to the lower stage insertion port 7D of the first attachment 7 and the insertion port 8A of the second attachment 8. The front portions 3A of the article support member 3 are respectively inserted to the upper stage insertion ports 7C of the first attachment 7. The rear portion of the article support member 3 is mounted on the rigid plate 4.
In a specific example (a manufacturing embodiment) (cf. FIG. 2), an inclination of the rigid plate 4 and the article support member 3 is set to 2 degree. Further, a distance from the main body portion 8B of the second attachment 8 to the rear end of the article support member 3 is set to 8 mm, an insertion amount of the front portion 3A of the article support member 3 to the upper stage insertion port 7C is set to 5 mm, a total length of the article support member 3 is set to 637 mm, and a total length of the rigid plate 4 is set to 645 mm. Accordingly, in the case of detaching the article support member 3 for a maintenance, it is possible to slide the article support member 3 rearward (while detaching from the upper stage insertion port 7C) so as to easily detach the article support member 3.
In FIG. 3, a decline of the article support member 3 is sharpened more than a state in FIG. 2, by inverting vertically the second attachment 8 in the state shown in FIG. 2. In this case, an angle of gradient between the rigid plate 4 and the article support member 3 is set to 4 degrees.
FIGS. 4 and 5 show dimensions (mm unit) of the specific example of the first and second attachments 7 and 8, respectively. The main body portion 7B of the first attachment 7 is of a hollow elongated square pole shape, the groove 7A is formed by forming an L-shaped portion 7E on a back face of the main body portion 7B, an upper rib-shaped portion 7F and a lower rib-shaped portion 7G are formed in a front face of the main body portion 7B, and a disc-like intermediate rib-shaped portion 7H having a spring property is formed in an intermediate portion. The second attachment 8 has dimensions shown in FIG. 5. These attachments 7 and 8 are constructed by an extrusion molded product of aluminum. It is easy to achieve extrusion moldings which are light and rigid and have various shapes by using aluminum as the material.
FIG. 6 shows a cross section of a state in which a transparent front face stopper 9 such as an acrylic plate or the like is attached to the groove 7A of the first attachment 7. It is possible to prevent articles from falling off from the front side, by means of the front face stopper 9.
FIG. 7 is a partly omitted plan view of the article support member 3. The article support member 3 is provided with a lot of retainer grooves 12 and 13 in parallel for attaching a partition plate 11 in front and rear sides of a rectangular base plate 10. Both right and left sides of the base plate 10 are provided with retainer lacking portions 16 for attaching side face fences 14 and 15 (cf. FIG. 8). The retainer lacking portions 16 are formed at four positions per one side face fence 14 (cf. FIG. 1), and the retainer lacking portions for the side face fence 15 are formed in the same manner on an opposed side surface to a direction shown in FIG. 8. Further, in close vicinity to a center portion and front and rear edges of the base plate 10, retainer grooves 17 to 19 (cf. FIG. 1, too) of the compartment plate 11 are provided in parallel to the retainer grooves 12 and 13 and in correspondence thereto, and installation grooves 20 of the rollers 6, which support the articles, are provided between the retainer grooves 12, 13 and 17 to 19. The rollers 6 are provided rotatably in the installation grooves 20. A shaft 6A of the roller 6 is supported by a common plane edge 21 in an edge portion of the installation groove 20.
A groove 23 provided in a bearing stripe 22A of the cover 22 is fitted to the shaft 6A of the roller 6, as shown in FIG. 9. Further, the roller cover 22 is provided with a closure member 22B, as shown in FIG. 10, closes a gap between the rollers 6, and is structured so that a rolling friction is generated between the articles and the roller 6 and a sliding friction is generated between the articles and the closure member 22B. The articles automatically move by making a sum of the rolling friction and the sliding friction smaller than a movement component force generated by its own weight of the articles.
A whole of the roller cover 22 is provided with the closure member 22B filling in the gap between a through hole 22C for exposing an upper peripheral surface of the roller 6 and the roller 6, as shown in FIG. 11, and the closure member 22B is integrally formed by a synthetic resin material in the roller cover 22. An upper surface of the roller cover 22 is structured so as to be somewhat lower than the topmost surface of the roller 6 at a time of setting.
The structure of the article support member 3 as mentioned above is only one example, and it is possible to use various structures, for example, the structures described in Japanese Patent Application Laid-open No. 8-24091, Japanese Patent Application Laid-open No. 10-5082 and the like, as long as the rollers 6, which support the articles, are rotatably installed in parallel in the main body base 6 which is formed as a tabular shape as a whole, so as to be vertical to the moving direction of the articles. Further, the structure may be made so that a simply frame shaped main body base 5 is integrally formed by a synthetic resin material, and the rollers 6 are only provided in the main body base 5. It is possible to prevent the distortion of the frame body, that is, the main body base 5 even if the heavy articles are mounted on the rollers 6, by structuring so as to support the frame body of the main body base 5 supporting the shaft 6A of the roller 6 by the rigid plate 4 from below.
The structures of the first and second attachments 7 and 8 are not limited to the illustrated ones. It is not limited to the method of fitting the article support member 3 and the rigid plate 4 to the attachments 7 and 8, but a method of screwing them to the attachments 7 and 8 may be employed. Further, the first and second attachments 7 and 8 and the rigid plate 4 are formed by a manufacturing method of extruding a heated aluminum alloy through a die metal mold, however, may be formed by a synthetic resin material. In the case of forming the attachments 7 and 8 and the rigid plate 4 by a synthetic resin, it is necessary to take a rigidity into consideration in such a manner as to prevent the distortion from being generated by the articles weight. In the present example, the first attachment 7 and the second attachment 8 which are installed to the article support member 3 and the rigid plate 4 are mounted to the shelf plate 2, however, a magnet may be attached to the bottom surfaces of the fist attachment 7 and the second attachment 8 so as to be fixed to the shelf plate 2, as well as the first attachment 7 and the second attachment 8 are fixed by a screw or the like. Further, the rigid plate 4 as used has a dimension or size approximately the same as the shelf plate 2, however, in the case that it is used only in a predetermined area of the shelf plate 2, a smaller shelf plate than the shelf plate 2 may be used. Same applies to the size or dimension of the article support member 3.
