Description

Display shelf boards and display shelves

[0001] The present invention relates to a shelf board for a display shelf and a display shelf.

[0002] In food retailers such as supermarkets and convenience stores, products are displayed and sold on shelves in walk-in refrigerators, insulated / heated cases, etc. Examples of products displayed on shelves (hereinafter referred to as "displayed products") include liquids such as soft drinks stored in cans or plastic bottles. The displayed products are arranged on the shelves in a line from the front side (e.g., the storefront side) to the back side (e.g., the back room side).

[0003] When a consumer picks up an item from the front of a display shelf, a space is left empty. This requires store staff to move the item to the front and refill the space. However, this process requires a lot of time and effort.

[0004] Therefore, in order to solve the above problems, an item moving device has been proposed as a means for smoothly moving displayed items from the back to the front, which includes multiple roller members, a base member having a bottom plate portion that rotatably houses the multiple roller members and a peripheral wall portion that rises from the periphery of the bottom plate portion, and a plate-shaped cover member that is detachably arranged in an opening surrounded by the peripheral wall portion with a portion of the peripheral surface of the multiple roller members protruding (Patent Document 1).

[0005] However, the above-mentioned item transport devices require a long time for installation and maintenance, and are prone to damage. For example, installation must be carried out carefully because the roller members may fall off and be damaged. Furthermore, dust and other particles that accumulate between the roller members are difficult to remove, making the removal process time-consuming. Furthermore, the above-mentioned item transport devices have a complex structure, resulting in high manufacturing costs.

[0006] Therefore, it has been proposed to use a metal plate with excellent slip resistance, which has a coating film formed on the surface of a metal plate with multiple protrusions formed on the surface by embossing, as a shelf for a display shelf (Patent Documents 2 and 3).

[0007] International Publication No. 2016 / 052650 Japanese Patent Application Laid-Open No. 2005-96442 Japanese Patent Application Laid-Open No. 2007-83172

[0008] However, while the metal plates described in Patent Documents 2 and 3 provide good sliding properties for display items, they are prone to deflection due to the mass of the display items. When the metal plate deflects, the contact state between the bottom of the display item and the protruding portion of the metal plate changes depending on the location, making it difficult to move the display item smoothly. Furthermore, because the bottom of the display item and the protruding portion of the metal plate are in near-point contact, the mass of the display item is concentrated at the protruding portion of the metal plate. As a result, the coating film formed on the surface of the metal plate is prone to peeling, and the frictional resistance at the contact point between the bottom of the display item and the protruding portion of the metal plate increases, reducing the sliding properties of the display item.

[0009] The present invention has been made to solve the above-mentioned problems, and aims to provide shelves for display shelves and a display shelf that are less likely to warp, allow display items to be moved smoothly, are easy to install and maintain, and can reduce costs.

[0010] As a result of extensive research into display shelf shelves, the inventor discovered that all of the above problems could be solved by forming a convex portion of a predetermined shape on the surface of the display shelf shelf, and thus completed the present invention.

[0011] In other words, the present invention is a shelf board for a display shelf for moving display items in a predetermined direction, which has a surface including a plurality of convex portions in a cross section perpendicular to the direction of movement of the display items, the top surfaces of the plurality of convex portions are curved and / or flat, the plurality of convex portions extend between both ends perpendicular to the direction of movement of the display items, and the bottom of one of the display items is capable of contacting the plurality of convex portions.

[0012] The present invention also provides a display shelf including the above-described display shelf board.

[0013] According to the present invention, it is possible to provide shelves for display shelves and display shelves that are less likely to warp, allow display items to be moved smoothly, are easy to install and maintain, and can reduce costs.

FIG. 4 is a top view of a display shelf shelf according to an embodiment of the present invention. FIG. 5 is a top view of another display shelf shelf according to an embodiment of the present invention. FIG. 6 is a partially enlarged cross-sectional view parallel to the direction of movement of display items of a protruding portion of a display shelf shelf according to an embodiment of the present invention. FIG. 7 is a partially enlarged cross-sectional view parallel to the direction of movement of display items of a protruding portion of another display shelf shelf according to an embodiment of the present invention. FIG. 8 is a partially enlarged cross-sectional view parallel to the direction of movement of display items of a protruding portion of another display shelf shelf according to an embodiment of the present invention.

[0015] The following is a detailed description of the embodiments of the present invention. The present invention is not limited to the following embodiments, and it should be understood that modifications and improvements made to the following embodiments based on the ordinary knowledge of those skilled in the art without departing from the spirit of the present invention are also within the scope of the present invention.

[0016] A display shelf (hereinafter sometimes abbreviated as "shelf") according to an embodiment of the present invention is used to display items on a display shelf. In this specification, "display shelf" refers to a fixture (e.g., a walk-in refrigerator, a warming / heating case, etc.) used to display items for consumers in food retail stores such as supermarkets and convenience stores. Furthermore, a "display shelf" refers to one of the components that make up a display shelf, equipped with a mechanism for placing and smoothly moving display items in a predetermined direction. Conventional display shelves often have an item mover with a roller member mounted on a base plate supported by a bracket (shelf support). The base plate is a plate-shaped member provided to support the item mover.

[0017] The shelf board according to the embodiment of the present invention has a function of moving display items in a predetermined direction. Specifically, when the shelf board is installed on a display shelf, the shelf board has a function of moving display items aligned from the front side (e.g., the storefront side) to the back side (e.g., the back room side) of the display shelf from the back side to the front side. Display items include, but are not limited to, beverages such as soft drinks contained in cans or plastic bottles.

[0018] FIG. 1 is a schematic diagram illustrating the arrangement of shelves on a display shelf. As shown in FIG. 1, the shelf 10 is arranged on the display shelf so as to slope downward toward the movement direction X of the display items P. The shelf 10 can be fixed directly to the display shelf support 1 with a fixing jig such as a bolt (not shown). The shelf 10 may also be arranged on a bracket (shelf support) (not shown) fixed to the display shelf support 1 with a fixing jig such as a bolt (not shown), or on a base plate (not shown) arranged on the bracket. In FIG. 1, the left side is the storefront side, and the right side is the backroom side. The structure of the display shelf is not particularly limited as long as it allows the shelf 10 to be arranged as described above.

[0019] 2A and 2B are enlarged partial cross-sectional views of a shelf 10 according to an embodiment of the present invention, perpendicular to the direction X of movement of display items P. As shown in FIGS. 2A and 2B, the shelf 10 according to an embodiment of the present invention has a surface including multiple protrusions 13 in a cross section perpendicular to the direction X of movement of display items P. FIG. 2A shows an example in which the top surfaces of the multiple protrusions 13 are curved, while FIG. 2B shows an example in which the top surfaces of the multiple protrusions 13 are flat. Although not shown, the top surfaces of the multiple protrusions 13 may be a combination of curved and flat surfaces. Herein, the term "protrusion 13" refers to a portion of the surface of the shelf 10 that is elevated above the lowest bottom portion 14. Furthermore, the term "top surface of protrusion 13" refers to a surface including the highest portion of the protrusion 13 of the shelf 10.

[0020] The slipperiness of the display items P on the shelf 10 is affected by the size of the contact area between the surface of the shelf 10 and the bottom of the display items P. That is, if the contact area between the surface of the shelf 10 and the bottom of the display items P is too large, frictional resistance increases, reducing the slipperiness of the display items P on the shelf 10. On the other hand, if the contact area between the surface of the shelf 10 and the bottom of the display items P is too small, the mass of the display items P will concentrate at the contact area, increasing frictional resistance and reducing the slipperiness of the display items P on the shelf 10. Furthermore, the rigidity of the shelf 10 will not be ensured, which will make the shelf 10 more likely to bend and make it difficult to stably place the display items P on the shelf 10. Therefore, from the perspective of stably placing the display items P on the shelf 10 while ensuring rigidity and slipperiness, the shelf 10 is configured so that the bottom of each display item P can come into contact with multiple protrusions 13. The shelf board 10 is preferably configured so that the bottom of one display item P can come into contact with 2 to 20 protrusions 13, and more preferably so that the bottom of one display item P can come into contact with 2 to 10 protrusions 13. By using such a configuration, the above-mentioned effects can be ensured even more stably.

[0021] 3A to 3D are top views of a shelf board 10 according to an embodiment of the present invention. As shown in FIGS. 3A to 3D, in the shelf board 10 according to an embodiment of the present invention, multiple protrusions 13 extend between opposite ends E1 and E2 perpendicular to the direction X of movement of the display items P. FIG. 3A shows an example in which the multiple protrusions 13 are arranged parallel to the direction X of movement of the display items P and in a linear manner. FIG. 3B shows an example in which the multiple protrusions 13 are arranged non-parallel (inclined) and in a linear manner with respect to the direction X of movement of the display items P. FIG. 3C shows an example in which the multiple protrusions 13 are arranged parallel to the direction X of movement of the display items P and in a zigzag (non-linear) manner. FIG. 3D shows an example in which the multiple protrusions 13 are arranged parallel to the direction X of movement of the display items P and in a wavy (non-linear) manner with respect to the direction X of movement of the display items P. The shapes of the multiple protrusions 13 illustrated in FIGS. 3A to 3D are merely typical examples, and any shape may be used as long as they extend between the opposite ends E1 and E2. That is, the multiple protrusions 13 extending between the ends E1 and E2 may be parallel or non-parallel to the movement direction X of the display items P, and may be linear or non-linear. Furthermore, although not shown, the multiple protrusions 13 extending between the ends E1 and E2 may be a combination of the above-mentioned shapes (for example, a combination of parallel and non-parallel protrusions 13, or a combination of linear and non-linear protrusions 13, relative to the movement direction X of the display items P). By having the multiple protrusions 13 extend between the ends E1 and E2 in this way, the shelf board 10 is less likely to flex due to the mass of the display items P. This prevents the display items P from becoming difficult to move due to flexing of the shelf board 10.

[0022] Among the above-mentioned shapes, the multiple protrusions 13 extending between the ends E1 and E2 are preferably non-linear. The non-linear configuration of the multiple protrusions 13 increases the rigidity of the shelf 10 compared to linear configurations. In particular, when the shelf 10 is made of metal plate, the amount of processing required is greater than with linear configurations, and work hardening improves the rigidity of the shelf 10. Furthermore, when the multiple protrusions 13 are non-linear, the contact area between the bottom of the display item P and the protrusions 13 changes as the display item P moves in the movement direction X, causing a rocking action on the display item P in a direction parallel to the surface of the protrusions 13, thereby improving the sliding properties of the display item P. Furthermore, the multiple protrusions 13 extending between the ends E1 and E2 are preferably arranged non-parallel to the movement direction X of the display item P. Even when multiple protrusions 13 are arranged non-parallel to the movement direction X of the display item P, the contact area between the bottom of the display item P and the protrusions 13 changes as the display item P moves in the movement direction X, thereby improving the slipperiness of the display item P.

[0023] 4A to 4C are enlarged cross-sectional views of the protruding portion 13 (the highest portion) of the shelf 10 according to an embodiment of the present invention, taken along a plane parallel to the direction X of movement of the display items P. The cross-sectional shape of the protruding portion 13 parallel to the direction X of movement of the display items P is not particularly limited, but as shown in FIG. 4A, the surface of the protruding portion 13 may have a step in the cross-section parallel to the direction X of movement of the display items P. Furthermore, as shown in FIG. 4B, the surface of the protruding portion 13 may have a discontinuity (e.g., a recess) in the cross-section parallel to the direction X of movement of the display items P. Among these cross-sectional shapes, it is preferable that the surface of the protruding portion 13 have a step in the cross-section parallel to the direction X of movement of the display items P. Providing a step increases the rigidity of the shelf 10 compared to a case where the surface is parallel. In particular, when the shelf board 10 is made of a metal plate, the amount of processing is greater than in the case of a parallel surface, and work hardening improves the rigidity of the shelf board 10. Furthermore, when the display item P moves in the movement direction X, the step portion causes a rocking action on the display item P in a direction perpendicular to the surface of the protrusion 13, improving the sliding properties of the display item P.

[0024] When the top surfaces of the multiple protrusions 13 of the shelf board 10 are curved, it is preferable that the distance L1 between the vertices C1 of adjacent protrusions 13 is 4 to 8 mm and the radius of curvature of each protrusion 13 is 3 to 6 mm in a cross section (see FIG. 2A) perpendicular to the movement direction X of the display items P. By controlling the distance L1 and the radius of curvature within these ranges, the sliding properties of the display items P can be stably improved.

[0025] When the top surfaces of the multiple protrusions 13 of the shelf 10 are flat, the distance L2 between the center points C2 of adjacent protrusions 13 is preferably 4 to 10 mm, and the length L3 of the flat area of ​​each protrusion 13 is preferably 2 to 6 mm, in a cross section perpendicular to the direction X of movement of the display items P (see FIG. 2B ). By controlling the distance L2 and the length L3 within these ranges, the sliding properties of the display items P can be stably improved. Furthermore, in a cross section perpendicular to the direction X of movement of the display items P, both ends E3 of the flat area preferably have curved portions, with a radius of curvature of 0.05 to 1.5 mm. By providing curved portions of this shape at both ends E3 of the flat area, the display items P are less likely to be damaged by the protrusions 13. Furthermore, the sliding properties of the display items P are improved because the corners of both ends E3 do not impede the sliding properties of the display items P when they move in the direction X.

[0026] In the cross section of the shelf board 10 perpendicular to the direction X of movement of the display items P (see Figures 2A and 2B), the height H of the convex portions 13 is preferably 0.05 to 1.0 mm. By controlling the height H of the convex portions 13 within this range, it is possible to stably improve the rigidity of the display items P in the direction X of movement and the sliding properties of the display items P. Here, in this specification, the height H of the "convex portions 13" means the height from the lowest bottom portion 14 on the surface of the shelf board 10 to the apex of the convex portions 13.

[0027] The base material constituting the shelf board 10 according to the embodiment of the present invention is not particularly limited, and metal plates, resin plates, paper, and the like can be used. A surface treatment film may also be formed on the surface of the base material. Among these, the shelf board 10 according to the embodiment of the present invention preferably includes a stainless steel plate 11 and a surface treatment film 12 formed on the surface of the stainless steel plate 11, as shown in FIGS. 2A and 2B . Using a stainless steel plate 11 as the base material of the shelf board 10 ensures the strength of the shelf board 10. In other words, the high rigidity of the stainless steel plate 11 makes it less likely to deform due to the mass of the display items P. Therefore, the shelf board 10 can be directly fixed to the display shelf support 1 with a fixing jig such as a bolt, or can be placed on a bracket (shelf support) fixed to the display shelf support 1 with a fixing jig such as a bolt. Furthermore, using a stainless steel plate 11 improves the corrosion resistance of the shelf board 10, and the unique design characteristics of the stainless steel plate 11 impart a clean appearance. Furthermore, by forming the surface treatment film 12 on the surface of the stainless steel plate 11, the stainless steel plate 11 can be protected while improving the slipperiness of the display items P (ease of movement in the movement direction X).

[0028] The stainless steel plate 11 used for the shelf 10 is not particularly limited, and various stainless steel plates such as austenitic stainless steel plate and ferritic stainless steel plate can be used. Among them, austenitic stainless steel plate is preferred from the viewpoints of corrosion resistance and workability, and austenitic stainless steel plate with a bright annealed finish is particularly preferred from the viewpoint of design. Examples of austenitic stainless steel plate include SUS304, SUS316, SUS312L, and SUS302.

[0029] When stainless steel plate 11 is used as the base material of shelf board 10, the thickness of stainless steel plate 11 is not particularly limited, but is preferably 0.1 to 3.0 mm, and more preferably 0.4 to 2.0 mm. By controlling the thickness of stainless steel plate 11 within this range, the strength of shelf board 10 as a base material can be stably ensured.

[0030] A through hole 15 may be provided in a portion of the shelf board 10. Fig. 5 shows a top view of the shelf board 10 including a stainless steel plate 11 with a through hole 15 provided in a portion thereof. By providing the through hole 15 in a portion of the stainless steel plate 11, cold air or warm air circulating inside the display shelf can pass through the shelf board 10, thereby enabling the display items P to be cooled or heated / kept warm quickly.

[0031] The shape of the through holes 15 is not particularly limited, and can be various shapes such as circular, polygonal, elliptical, etc. The number of through holes 15 is not particularly limited as long as the strength of the stainless steel plate 11 serving as the base material of the shelf board 10 can be ensured. The position of the through holes 15 is not particularly limited, but it is preferable that they be provided in the bottom 14. By providing the through holes 15 in the bottom 14, it is possible to prevent a decrease in the slipperiness of the display items P.

[0032] The surface treatment film 12 formed on the surface of the stainless steel plate 11 may be formed on the side on which the display items P are placed, but may also be formed on the side on which the display items P are not placed. The surface treatment film 12 formed on the surface of the stainless steel plate 11 is not particularly limited, and may be any of various types of film, such as a resin film, a ceramic film, or a plating film. The surface treatment film 12 has the function of improving the slipperiness of the display items P while protecting the stainless steel plate 11.

[0033] However, because the shelf 10 improves the slipperiness of the display items P by the multiple protrusions 13 formed on its surface, the slipperiness of the surface treatment film 12 itself does not need to be very high. However, by selecting a surface treatment film 12 with good slipperiness, the slipperiness of the display items P can be further improved. The dynamic friction coefficient of the surface treatment film 12 is not particularly limited, but it is preferable that the dynamic friction coefficient measured in accordance with JIS K7125:1999 be 0.10 or less. By selecting a surface treatment film 12 with a friction coefficient within this range, the slipperiness of the display items P can be stably improved. Examples of surface treatment films 12 with good slipperiness include fluororesin films, DLC (diamond-like carbon) films, chromium carbide plating films, and silicon-based films. The surface treatment film 12 may also be formed using a resin composition that provides a coating film with good slipperiness. For example, the surface treatment film 12 may be formed using a commercially available water- and oil-repellent treatment agent (e.g., Fluorosurf (registered trademark) from Fluorotechnology Co., Ltd.), or the surface treatment film 12 may be formed by performing AC Coat from Asahi Chiyoda Kogyo Co., Ltd.

[0034] The thickness of the surface treatment film 12 is not particularly limited, but is preferably less than 1 μm. By controlling the thickness within this range, it is possible to prevent the surface of the surface treatment film 12 from becoming too rough and to prevent peeling of the surface treatment film 12. The lower limit of the thickness of the surface treatment film 12 is not particularly limited, but is preferably 0.05 μm or greater in order to ensure the above-mentioned effects.

[0035] The method for manufacturing the shelf board 10 according to the embodiment of the present invention is not particularly limited, and the shelf board 10 can be manufactured according to a known method. For example, the method for manufacturing the shelf board 10 according to the embodiment of the present invention includes a processing step of forming a plurality of protrusions 13 on the stainless steel plate 11, and a surface treatment step of forming the surface treatment film 12 on the surface of the stainless steel plate 11.

[0036] In the processing step, the method for forming the plurality of protrusions 13 on the stainless steel sheet 11 is not particularly limited, and press working, roll forming, or the like can be used. For example, when passing the stainless steel sheet 11 between rolling rolls to form it, a rolling roll having a predetermined uneven shape can be used, and the surface shape of the rolling roll can be transferred to the stainless steel sheet 11 to form the protrusions 13. Therefore, when forming the protrusions 13 on only one surface of the stainless steel sheet 11, it is sufficient to form recesses corresponding to the protrusions 13 only on the rolling roll that comes into contact with that surface. In the surface treatment step, the method for forming the surface treatment film 12 on the surface of the stainless steel sheet 11 is not particularly limited and can be appropriately selected depending on the type of surface treatment film 12 to be formed. For example, when forming a resin film as the surface treatment film 12, a resin composition that provides the resin film can be applied to the stainless steel sheet 11, and the applied film can then be cured.

[0037] A display shelf according to an embodiment of the present invention includes a shelf board 10. In the display shelf according to an embodiment of the present invention, as shown in Fig. 1, the shelf board 10 is preferably arranged so as to slope downward toward the direction X of movement of the display items P. By arranging the shelf board in this manner, when some of the display items P in the front row on the downwardly sloping lower side (left side: storefront side) are removed, the display items P in the rear row can slide to the front row by gravity.

[0038] The inclination angle of the shelf 10 (the inclination angle of the surface of the shelf 10 relative to the horizontal plane) is not particularly limited, but from the viewpoint of stably ensuring the above-mentioned effects, it is preferably 1.0° or more, more preferably 2.0 to 30.0°, even more preferably 2.0 to 15.0°, and particularly preferably 2.0 to 10.0°.

[0039] In Figure 1, the shelf board 10 is fixed directly to the display shelf support 1, but it is also possible to provide a bracket (shelf support) on the display shelf support 1 and place the shelf board 10 on top of that. Alternatively, a base plate may be placed on the bracket (shelf support), and the shelf board 10 may be placed on the base plate. By providing a base plate, the shelf board 10 is less likely to deform due to the mass of the display items P. Therefore, when a base plate is provided, the thickness of the stainless steel plate 11 that constitutes the shelf board 10 can be reduced.

[0040] The display shelf according to the embodiment of the present invention may further include a partition plate arranged on the shelf board 10 along the movement direction X of the display items P. By providing the partition plate, it becomes easier to place different types of display items P on the shelf board 10.

[0041] The shelf board 10 according to the embodiment of the present invention has a simpler structure than shelves (item movers) with roller members, making installation and maintenance easier and less prone to breakage, thereby reducing various costs. Furthermore, compared to conventional shelves with a coating formed on the surface of a metal plate, the shelf board 10 according to the embodiment of the present invention has a surface with a predetermined convex shape, making it more rigid and less prone to bending. In particular, when a stainless steel plate 11 is used as the base material for the shelf board 10, the shelf board 10 has excellent durability and corrosion resistance and is less prone to deterioration over time. Furthermore, the shelf board 10 according to the embodiment of the present invention can be easily adjusted to suit the display shelf to be used, allowing it to be used as a replacement for conventional shelves with roller members in display shelves. Furthermore, because the shelf board 10 according to the embodiment of the present invention uses a stainless steel plate 11 as the base material, it is highly recyclable and has a low environmental impact.
