Description

[Technical field]

[0001] The present invention relates to a card rail that is attached to the front end of a product display shelf such as a showcase, and that holds information cards or the like on which product information is written. [Background technology]

[0002] The card rail of the present invention also serves as a fall prevention device that prevents products placed on a product display shelf from falling forward, and can also displace the position of a card holder that holds an information card to a position that does not get in the way when replenishing products. A conventional example of this type of card rail is disclosed in Patent Document 1 (title of invention: shelf device). The card rail of Patent Document 1 includes a card holder (decorative plate) that holds an information card (product display card), and locking pieces that are fixed to the left and right ends of the card holder. Each of the locking pieces has an L-shaped slit, and each locking piece is connected to the product display shelf by a screw that is screwed into the side of the product display shelf (shelf board) through the slit. The card rail is rotatable around the screw.

[0003] The card rail can be displaced between a position where the card holder protrudes above the top surface of the product display shelf (hereinafter referred to as the "upper position") and a position where the card holder is below the top surface of the product display shelf (hereinafter referred to as the "lower position"). Specifically, from the upper position, an operator can lift the card holder upward, pull the card holder out toward the front, and then rotate the card holder downward around the screw, thereby displacing the card rail to the lower position. Also, from the lower position, an operator can rotate the card holder upward around the screw, push the card holder into the back, and then push the card holder downward, thereby displacing the card rail to the upper position.

[0004] [Patent Document 1] Microfilm of Utility Model Application No. 49-58866 (Utility Model Application No. 50-146498) Summary of the Invention [Problem to be solved by the invention]

[0005] In the card rail of Patent Document 1, by placing the card holder in the upper position, the card holder can receive products on the product display shelf while holding an information card, thereby preventing the products from falling off the product display shelf. Also, by placing the card holder in the lower position, products can be refilled onto the product display shelf or products can be removed from the product display shelf without the card holder getting in the way. However, when the card holder is in the lower position, the information card is oriented downward, so the purchaser cannot read the product information written on the information card. Also, if the worker forgets to shift the card holder to the upper position after refilling the products and the card holder remains in the lower position, the purchaser cannot read the product information written on the information card.

[0006] To provide a card rail configured so that the card holder can be displaced between an upper position in which the card holder protrudes above the product placement surface and a lower position in which the card holder is positioned below the product placement surface, and to enable product information written on an information card to be read from the front whether the card holder is in the upper or lower position. [Means for solving the problem]

[0007] The present invention is directed to a card rail comprising an attachment section 29 attached to the front end section of a product display shelf 7, a card holder 31 for holding an information card 30 on which product information is written, and a hinge structure 32 for supporting the card holder 31 on the attachment section 29, the card holder 31 being configured to be displaceable between an upper position in which at least a part of the display surface of the information card 30 protrudes above the mounting surface 21 of the product display shelf 7 and a lower position in which the entire information card 30 is positioned below the mounting surface 21 of the product display shelf 7 by the hinge structure 32. The hinge structure 32 is characterized by being configured as a parallel biaxial hinge comprising a first hinge 48 connected to the attachment section 29 and extending in the left-right direction, a second hinge 49 connected to the upper end of the card holder 31 and extending in the left-right direction, and a hinge base 50 connecting both hinges 48, 49.

[0008] The card holder 31 comprises a holder body 41 that holds the information card 30, and a hanging wall 42 that protrudes rearward from the rear surface of the holder body 41. A locking step 51 that locks the tip of the hanging wall 42 is formed at the connection base with the first hinge 48 of the mounting section 29. Then, with the second hinge 49 positioned above the first hinge 48, the tip of the hanging wall 42 is locked with the locking step 51, thereby restricting rotation around the first and second hinges 48 and 49, and the card holder 31 is maintained in the upward position.

[0009] When the locking step 51 is released from the suspension wall 42, the card holder 31 and the hinge base 50 hang down by their own weight, so that the card holder 31 is in a downward position.

[0010] The first and second hinges 48 and 49 are made of resin.

[0011] The mounting portion 29, the card holder 31 and the hinge structure 32 are formed as a single unit using resin as a material. Effect of the Invention

[0012] Like the card rail of the present invention, when hinge structure 32 is configured with a parallel biaxial hinge including a first hinge 48 connected to mounting portion 29 and extending in the left-right direction, a second hinge 49 connected to the upper end of card holder 31 and extending in the left-right direction, and a hinge base 50 connecting both hinges 48, 49, the posture of card holder 31 can be changed between an upward posture and a downward posture without changing the forward orientation of card holder 31.

[0013] More specifically, in the card rail of the present invention, as shown in FIG. 1, the hinge base 50 is raised so as to face upward from the mounting portion 29 via the first hinge 48, and the card holder 31 is tilted downward so as to face diagonally downward from the upper end of the hinge base 50 via the second hinge 49, thereby enabling the card holder 31 to be in an upward position; and as shown in FIG. 3, the hinge base 50 is tilted downward so as to face downward from the mounting portion 29 via the first hinge 48, and the card holder 31 is in a substantially vertical position so as to face downward from the lower end of the hinge base 50 via the second hinge 49, thereby enabling the card holder 31 to be in a downward position. In addition, in the card rail according to the present invention, the hinge structure 32 supporting the card holder 31 relative to the mounting portion 29 is configured with a parallel two-axis hinge, so that when displacing from the upper position to the lower position or from the lower position to the upper position, the first hinge 48 and the second hinge 49 can be rotated in opposite directions to make the surface oriented toward the front of the card holder 31 the same surface. More specifically, when displacing from the upper position in FIG. 1 to the lower position in FIG. 3, the first hinge 48 is rotated counterclockwise and the second hinge 49 is rotated clockwise, so that the position of the card holder 31 can be changed without changing the surface oriented toward the front of the card holder 31. Also, when displacing from the lower position in FIG. 3 to the upper position in FIG. 1, the first hinge 48 is rotated clockwise and the second hinge 49 is rotated counterclockwise, so that the position of the card holder 31 can be changed without changing the surface oriented toward the front of the card holder 31. As described above, with the card rail of the present invention, the display surface of the information card 30 containing product information can be oriented forward in both the upper and lower positions, allowing the purchaser to read the product information listed on the information card 30 from the front in both the upper and lower positions.

[0014] The card holder 31 includes a holder body 41 for holding an information card 30, and a hanging wall 42 protruding backward from the rear surface of the holder body 41. A locking step 51 for locking the tip of the hanging wall 42 is formed at the base of the connection with the first hinge 48 of the mounting section 29. When the second hinge 49 is positioned above the first hinge 48, the tip of the hanging wall 42 is locked with the locking step 51, so that the rotation around the first and second hinges 48 and 49 is restricted and the card holder 31 can be maintained in the upper position. This allows the card holder 31 to be maintained in the upper position with a simple structure in which the tip of the hanging wall 42 is locked with the locking step 51, and the structure of the card rail can be simplified. In addition, the card holder 31 can be maintained in the upper position with a simple operation of locking the tip of the hanging wall 42 with the locking step 51, so that the worker's effort associated with changes in position can be reduced.

[0015] When the hanging wall 42 is released from the locking step 51, the card holder 31 and the hinge base 50 hang down under their own weight, so that the card holder 31 is configured to assume a downward position. This eliminates the need for a dedicated structure to maintain the card holder 31 in the downward position, and simplifies the structure of the card rail.

[0016] When the first and second hinges 48, 49 are made of plastic hinges, the cost of each hinge 48, 49 can be reduced compared to when both hinges 48, 49 are made of metal hinges such as flat hinges or flag hinges, thereby reducing the overall cost of the card rail.

[0017] If the mounting portion 29, card holder 31 and hinge structure 32 are formed as a single unitary molded product using resin, the card rail can be obtained relatively easily, for example by two-color molding using an extrusion molding machine, thereby making it possible to further reduce the overall cost of the card rail. [Brief description of the drawings]

[0018] [Figure 1]1 is a vertical sectional side view showing a state in which a card rail according to an embodiment of the present invention is attached to a product display shelf, with the card holder in an up position. FIG. [Diagram 2] FIG. 2 is a vertical cross-sectional side view of a refrigerated open showcase equipped with a card rail. [Diagram 3] 1 is a vertical sectional side view showing a state in which the card rail is attached to a product display shelf, with the card holder in a lowered position. FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] (Embodiment) An embodiment in which the card rail according to the present invention is applied to a product display shelf of a refrigerated open showcase is shown. In this embodiment, the front, rear, left, right, and up and down refer to the crossed arrows shown in Figs. 1 and 2 and the indications of front, rear, left, right, and up and down written near each arrow. As shown in Fig. 2, the refrigerated open showcase comprises a case body 1 made of a heat-insulating box having an opening on the front side, and a base 2 supporting the lower surface of the case body 1. The interior 3 surrounded by the case body 1 is divided into a display room 5 and a circulation passage 6 by an inner case 4 that is U-shaped when viewed from the side. In the display room 5 that opens to the front, product display shelves 7 for placing products such as food and beverages to be displayed are installed in multiple levels in the upper and lower directions. In the showcase in this embodiment, a total of three product display shelves 7 are installed, and a card rail 8 according to the present invention is attached to each product display shelf 7.

[0020] The circulation passage 6 is formed in a U-shape in a side view so as to surround the display room 5 from three sides. The circulation passage 6 is provided with a circulation fan 11 for forming an air flow in the passage 6 and an evaporator 12 for cooling the air flowing through the passage 6. A downward air outlet 13 is provided at the upper front end of the circulation passage 6, and an upward air inlet 14 is provided at the lower front end of the passage 6. When the circulation fan 11 is driven, the cold air cooled by the evaporator 12 is blown downward from the air outlet 13 to the air inlet 14, forming an air curtain of cold air in front of the display room 5. This air curtain cools the air in the display room 5 and blocks the intrusion of outside air into the display room 5. A compressor 16, a condenser 17, a condenser fan 18, etc. are installed in a machine room 15 formed in the base 2.

[0021] As shown in FIG. 1, the product display shelf 7 includes a shelf body 22 whose upper surface is a placement surface 21, a rail mounting frame 23 formed at the front end of the shelf body 22, and the like. As shown in FIG. 2, the shelf body 22 is formed in a rectangular box shape that is flat from top to bottom and opens at the bottom, and is supported by the case body 1 with a pair of brackets 24 on the left and right. The rail mounting frame 23 is formed with an L-shaped cross section by a vertical frame 25 consisting of a vertical wall and a horizontal frame 26 consisting of a horizontal wall connected to the lower end of the vertical frame 25, and the tip of the horizontal frame 26 is fixed to the lower front end of the shelf body 22 so that the vertical frame 25 faces the front end face of the shelf body 22 with a gap between them. The rail mounting frame 23 is provided across the left and right sides of the shelf body 22, and a mounting groove 27 is formed at the front end of the shelf body 22, surrounded by the front end face of the shelf body 22, the vertical frame 25, and the horizontal frame 26. The rail mounting frame 23 is composed of a reinforcing frame 22a provided to reinforce the front end portion of the product display shelf 7, and the portion of the reinforcing frame 22a located forward of the front end surface of the shelf main body 22 is the rail mounting frame 23.

[0022] The card rail 8 is an elongated body having a constant cross section in the left-right direction. As shown in Figs. 1 and 3, the card rail 8 includes an attachment section 29 attached to the rail attachment frame 23 (the front end of the product display shelf 7), a card holder 31 for holding an information card 30 on which information such as the product name and price is written, and a hinge structure 32 for supporting the card holder 31 on the attachment section 29. The attachment section 29 includes an insertion wall 35 having a folded line cross section that is fitted into the attachment groove 27, an upper cover wall 36 protruding forward from the upper end of the insertion wall 35, a front cover wall 37 extending downward from the front end of the upper cover wall 36, an upper regulating wall 38 provided rearward from the upper end of the insertion wall 35, and a lower regulating wall 39 provided diagonally downward rearward from the lower end of the front cover wall 37. The width dimension in the front-rear direction of the insertion wall 35 is set to be approximately the same as the groove width dimension in the front-rear direction of the attachment groove 27. The opposing gap between the front end of the insertion wall 35 and the rear surface of the front cover wall 37 is set to be approximately the same as the thickness dimension of the vertical frame 25 of the rail mounting frame 23.

[0023] The card holder 31 comprises a holder body 41 that holds the information card 30, and a suspension wall 42 that protrudes rearward from the rear surface of the holder body 41. The holder body 41 is formed of front and rear clamping walls 43, 44 that clamp the information card 30 from the front and rear, and a bottom wall 45 that connects the lower ends of the clamping walls 43, 44, and the suspension wall 42 protrudes rearward from the rear clamping wall 44. The front clamping wall 43 is formed slightly shorter than the rear clamping wall 44, and the gap between the front and rear clamping walls 43, 44 is configured to become wider as it goes downward.

[0024] Hinge structure 32 is composed of a parallel biaxial hinge including a first hinge 48 connected to mounting portion 29 and extending in the left-right direction, a second hinge 49 connected to the upper end of card holder 31 and extending in the left-right direction, and a hinge base 50 connecting both hinges 48, 49. Hinge base 50 is formed in the shape of a flat plate that is long in the left-right direction, and each of hinges 48, 49 is composed as a strip-shaped resin hinge that is long in the left-right direction.

[0025] One short-side end of the first hinge 48 is connected to the upper end of the insertion wall 35 of the mounting portion 29, and the other short-side end is connected to an end of the hinge base 50, so that the hinge base 50 can rotate about the first hinge 48 relative to the mounting portion 29 via the first hinge 48. One short-side end of the second hinge 49 is connected to the upper end of the rear clamping wall 44 of the card holder 31, and the other short-side end is connected to an end of the hinge base 50, so that the card holder 31 can rotate about the second hinge 49 relative to the hinge base 50 via the second hinge 49.

[0026] The mounting portion 29, the card holder 31, and the hinge base 50 are made of a resin material harder than the resin material forming the hinges 48 and 49. Specifically, the card rail 8 including the above elements (mounting portion 29, card holder 31, hinge base 50, and both hinges 48 and 49) is made of an extrusion molded product in which the resins constituting each element are integrally formed by two-color molding using an extrusion molding machine. It is also possible to form the hinges by cutting a long extrusion molded product to a predetermined length. Each of the hinges 48 and 49 is a resin hinge made of polypropylene (PP) having hinge properties. The mounting portion 29, the card holder 31, and the hinge base 50 are made of glycol-modified polyethylene terephthalate (PET-G), which has high transparency and excellent strength.

[0027] The card rail 8 is attached to the product display shelf 7 by inserting the insertion wall 35 into the mounting groove 27. Specifically, the mounting groove 27 and the insertion wall 35 are aligned above the mounting groove 27, and the mounting portion 29 is moved downward toward the product display shelf 7 to insert the insertion wall 35 into the mounting groove 27. At this time, the tip of the lower regulating wall 39 abuts against the front surface of the vertical frame 25, and the insertion wall 35 is inserted into the mounting groove 27 with the lower side of the front cover wall 37 being deflected and deformed in the forward direction. When the insertion wall 35 is inserted into the mounting groove 27, the lower surface of the upper regulating wall 38 eventually abuts against the placement surface 21, and the lower surface of the upper cover wall 36 abuts against the upper end of the vertical frame 25. The deflected front cover wall 37 is released from the abutment of the lower regulating wall 39 against the vertical frame 25 and returns to its original state. By the above procedure, the card rail 8 can be attached to the product display shelf 7.

[0028] When the card rail 8 is attached to the product display shelf 7, the movement of the mounting portion 29 in the front-rear direction relative to the rail mounting frame 23 is restricted by the insertion wall 35 fitting into the mounting groove 27 and the vertical frame 25 being inserted between the insertion wall 35 and the front cover wall 37. On the other hand, the movement of the mounting portion 29 in the up-down direction relative to the rail mounting frame 23 is restricted by the upper restriction wall 38 being received by the placement surface 21 and the upper cover wall 36 being received by the upper end of the vertical frame 25, and the movement of the mounting portion 29 in the up-down direction being restricted by the lower restriction wall 39 being received by the horizontal frame 26. The movement of the mounting portion 29 in the left-right direction relative to the rail mounting frame 23 is restricted by the friction between the insertion wall 35 and the mounting groove 27, the friction between the insertion wall 35 and the vertical frame 25, and the friction between the front cover wall 37 and the vertical frame 25. As described above, the card rail 8 is attached to the product display shelf 7 in a state in which the movement in each of the front-rear, up-down, and left-right directions is restricted. The outer surface of the vertical frame 25 of the rail mounting frame 23 is covered with an upper cover wall 36 and a front cover wall 37.

[0029] The card rail 8 attached to the product display shelf 7 is supported by the hinge structure 32 so that the card holder 31 can be displaced between an upper position (see FIG. 1) in which at least a part of the card holder 31 protrudes above the mounting surface 21 of the product display shelf 7 with the display surface of the information card 30 facing forward, and a lower position (see FIG. 3) in which the card holder 31 is entirely located below the mounting surface 21 of the product display shelf 7. Specifically, as shown in FIG. 1, the card holder 31 can be placed in the upper position by engaging the tip of the hanging wall 42 with the engaging step 51 in a state in which the second hinge 49 is located above the first hinge 48. At this time, the hinge base 50 stands upright above the mounting portion 29 via the first hinge 48. Meanwhile, the card holder 31 is inclined downward forward via the second hinge 49 in front of the hinge base 50.

[0030] 1, when the card holder 31 is in the upper position, the hanging wall 42 of the card holder 31 is locked to the locking step 51, so that the hinge base 50 connected to the mounting portion 29 via the first hinge 48 tries to rotate left (counterclockwise) about the first hinge 48 due to the weight of the hinge base 50 and the card holder 31. Meanwhile, the card holder 31 connected to the hinge base 50 via the second hinge 49 tries to rotate left (counterclockwise) about the second hinge 49 due to its own weight. However, the rotation moment about the first hinge 48 acting on the hinge base 50 and the rotation moment about the second hinge 49 acting on the card holder 31 are received in a bracing manner by the tip of the hanging wall 42 being pressed against the locking step 51. As a result, rotation around each hinge 48, 49 is restricted, and card holder 31 is maintained in the upward position. When card holder 31 is in the upward position in this manner, hinge base 50 and the upper half of card holder 31 are higher than placement surface 21. Furthermore, when hinge base 50 and the upper half of card holder 31 are higher than placement surface 21 in this manner, products on placement surface 21 can be received by hinge base 50 etc. Therefore, card rail 8 functions as a fall prevention device that prevents products placed on product display shelf 7 from falling forward.

[0031] When the suspended wall 42 is separated from the locking step 51 to release the locked state when the card holder 31 is in the upper position, the restriction on rotation around the hinges 48 and 49 is released, and the card holder 31 is displaced to the lower position. Specifically, when the card holder 31 is grasped with the fingers from the position shown in Fig. 1 and moved forward to release the locked state of the suspended wall 42 by the locking step 51, the card holder 31 becomes able to rotate around the first and second hinges 48 and 49. When the card holder 31 is further moved downward, the hinge base 50 rotates left (counterclockwise) around the first hinge 48, and the card holder 31 rotates right (clockwise) around the second hinge 49, and the card holder 31 is displaced to the lower position shown in Fig. 3.

[0032] 3, when the card holder 31 is in the downward position, the second hinge 49 is located lower than the first hinge 48. Also, when the card holder 31 is in the downward position, the hinge base 50 is received by the tip of the locking step 51. The hinge base 50 is inclined downwardly forward in front of the mounting portion 29, and the holder body 41 of the card holder 31 is in a substantially vertical position below the hinge base 50.

[0033] In FIG. 3, when the card holder 31 is in the lower position, the hinge base 50 rotates around the first hinge 48 by its own weight with respect to the mounting portion 29 and is received by the front end of the locking step portion 51. Meanwhile, the card holder 31 hangs down around the second hinge 49 by its own weight with respect to the hinge base 50. As described above, the hinge base 50 and the card holder 31 are maintained in the lower position by their own weight. Since the card holder 31 can be disposed below the placement surface 21 when in the lower position, the worker can replenish products on the product display shelf 7 without being hindered by the card holder 31. Since the display surface of the information card 30 is oriented forward even in the lower position, the purchaser can read the product information written on the display surface of the information card 30 even when replenishing products.

[0034] As described above, in the card rail 8 of this embodiment, the hinge structure 32 is configured with two parallel hinges that can rotate around the first and second hinges 48 and 49. Therefore, when displacing from the upper position to the lower position or from the lower position to the upper position, the first hinge 48 and the second hinge 49 can be rotated in opposite directions to make the surface oriented toward the front surface of the card holder 31 the same surface. Specifically, when displacing from the upper position of FIG. 1 to the lower position of FIG. 3, the first hinge 48 is rotated counterclockwise and the second hinge 49 is rotated clockwise, so that the position of the card holder 31 can be changed without changing the surface oriented toward the front surface of the card holder 31. Also, when displacing from the lower position of FIG. 3 to the upper position of FIG. 1, the first hinge 48 is rotated clockwise and the second hinge 49 is rotated counterclockwise, so that the position of the card holder 31 can be changed without changing the surface oriented toward the front surface of the card holder 31. As described above, in the card rail 8 according to this embodiment, the display surface of the information card 30 on which product information is written can be oriented forward in both the upper and lower positions, so that the purchaser can read the product information written on the information card 30 from the front in both positions. Incidentally, in the case where the hinge structure is a one-axis hinge, when the card holder 31 is rotated around the hinge axis extending in the left-right direction, the surface oriented forward is necessarily reversed before and after the rotation.

[0035] The hanging wall 42 protrudes rearward from the rear surface of the holder main body 41, and a locking step 51 for locking the tip of the hanging wall 42 is formed at the connection base with the first hinge 48 of the mounting portion 29, and by locking the tip of the hanging wall 42 with the locking step 51 with the second hinge 49 positioned above the first hinge 48, rotation around the first and second hinges 48 and 49 is restricted and the card holder 31 is maintained in the upper position, so that the card holder 31 can be maintained in the upper position with a simple structure in which the tip of the hanging wall 42 is locked with the locking step 51, and the structure of the card rail 8 can be simplified. Also, the card holder 31 can be maintained in the upper position with the simple operation of locking the tip of the hanging wall 42 with the locking step 51, so that the worker's effort associated with changes in position can be reduced.

[0036] When the engagement of the hanging wall 42 with the engagement step 51 is released, the card holder 31 and the hinge base 50 hang down by their own weight, so that the card holder 31 is configured to assume a downward position. This eliminates the need for a dedicated structure for maintaining the card holder 31 in the downward position, and simplifies the structure of the card rail 8.

[0037] Since the first and second hinges 48, 49 are made of plastic hinges, the cost of each hinge 48, 49 can be reduced compared to when both hinges 48, 49 are made of metal hinges such as flat hinges or flag hinges, thereby reducing the overall cost of the card rail 8.

[0038] Since the mounting portion 29, the card holder 31 and the hinge structure 32 are formed as a single unit using resin as a material, the card rail can be obtained relatively easily by performing two-color molding using an extrusion molding machine, for example, and the overall cost of the card rail 8 can be further reduced.

[0039] In the above embodiment, the mounting portion 29, the card holder 31, and the hinge structure 32 are configured as an integrally formed molded product, but the first and second hinges 48, 49 made of resin can be connected by bonding or fastening. The first and second hinges 48, 49 can be made of a relatively soft resin material that has flexibility. The first and second hinges 48, 49 can also be configured as metal hinges such as flat hinges or flag hinges. [Explanation of symbols]
