FIG. DETAILED DESCRIPTION OF THE INVENTION

[0014] An embodiment of the shelf of the present invention will be described below with reference to the drawings. The shelf of the present invention can automatically advance products by pulling out the movable plate in the forward direction and pushing it in the rearward direction. In the following description, the front direction of the shelf is designated as F, the rear direction as R, and the width direction as W. [First embodiment]

[0015] A shelf 10 according to a first embodiment will be described with reference to Figures 1 to 13. The shelf 10 is an example of the product advance device referred to in the present invention.

[0016] As shown in Figures 1 to 5, shelf 10 comprises a base 11, a pair of frames 12 standing up from the rear end and both end portions of base 11, a back panel 13 spanning between the pair of frames 12, a fixed portion 14 fixed to the pair of frames 12, a pair of brackets 15 fixed to each of the pair of frames 12, a pair of shelf rails 16 provided on the pair of brackets 15, a movable plate 17 (movable shelf) that can be pulled out in the forward direction F or pushed in in the rear direction R via the pair of shelf rails 16, a rail member 18 provided on movable plate 17, a forward-extension member 21 that can move in the front-to-rear direction on rail member 18, a hook member 22 that can move in the front-to-rear direction on rail member 18, a biasing member 23 that biases forward-extension member 21 and hook member 22 in a direction that brings them closer to each other, and a partition plate 24 that divides movable plate 17 in the front-to-rear direction.

[0017] Each of the pair of frames 12 has a plurality of through holes 25 arranged vertically for fixing the brackets 15. The plurality of through holes 25 may form two or more rows.

[0018] As shown in FIGS. 1 and 2 , the fixed portion 14 includes a pair of metal support brackets 26 detachably attached to the frame 12, a metal cross plate 27 extending between the pair of support brackets 26, and a resin flat plate 28 attached to the upper surface of the cross plate 27. The cross plate 27 and the flat plate 28 of the fixed portion 14 are provided across substantially the entire width of the movable plate 17 in the width direction W and are formed in a strip shape extending elongatedly in the width direction W. The flat plate 28 is detachably fixed to the cross plate 27 by engaging a claw or the like. As shown in FIG. 3 , the flat plate 28 has a first surface 28A and a second surface 28B opposite the first surface 28A. The second surface 28B of the flat plate 28 abuts against the cross plate 27. The first surface 28A of the flat plate 28 has a plurality of grooves 31 extending in the front-rear direction FR. As shown in FIG. 6, the flat plate 28 further has a recess 34 at the front end of the second surface 28B for hooking onto an anchor portion 32 of the rail member 18, which will be described later, and a hook portion 33 of the hook member 22, which will be described later.

[0019] As shown in Fig. 7, a pair of shelf board rails 16 are provided on the inner surfaces of the pair of brackets 15, respectively. Each of the pair of shelf board rails 16 is extendable and retractable in the front-to-rear direction FR, and can support the movable plate 17 so that it can slide in the front-to-rear direction FR. Therefore, the movable plate 17 is movable between a first position P1 where the rear end 17B overlaps with the fixed portion 14 (flat plate 28) as shown in Fig. 7, and a second position P2 where the front end 17A overlaps with the fixed portion 14 (flat plate 28) as shown in Fig. 1.

[0020] The movable plate 17 is formed into a flat plate shape using a metal plate. The movable plate 17 is provided directly below the fixed portion 14. As shown in FIG. 8 , the movable plate 17 has a front end 17A and a rear end 17B opposite the front end 17A. The movable plate 17 has a finger hook 17AA bent downward at the front end 17A. A store manager can pull the movable plate 17 from the second position P2 to the first position P1 by hooking a finger on the finger hook 17AA and pulling it toward themselves while unlocking a locking mechanism (not shown). The movable plate 17 has a standing piece 35 with a U-shaped cross section at the front end 17A, into which the insertion piece 42 of the rail member 18 or the insertion piece 42 of the partition plate 24 can be inserted. The standing piece 35 extends along the width direction W. The standing piece 35 is inserted and fixed into a horizontal groove 36 provided at the front end 17A. The standing piece 35 is a groove provided in the front end portion 17A of the moving plate 17 according to the present invention, and is an example of a groove into which the insertion piece 42 of the rail member 18 can be inserted.

[0021] As shown in FIG. 1, the rail member 18 is used by being placed on the movable plate 17. As shown in FIG. 11, a product 46 is placed on the rail member 18. As shown in FIG. 4, the rail member 18 is formed in an elongated rectangular shape and is placed on the movable plate 17 with its long side aligned in the front-to-rear direction FR. As shown in FIG. 4, the rail member 18 has a slide groove 41 provided on its top surface so as to extend in the front-to-rear direction FR, an insertion piece 42 provided at its front end, a slot 43 provided on its side surface and capable of accommodating the fixing portion 14 (the cross plate 27 and the flat plate 28), engagement portions 44 provided at an intermediate portion and a front side of the slot 43 in the front-to-rear direction FR, an anchor portion 32 provided at the frontmost side of the slot 43, and an expanded diameter portion 45 provided at the rear side of the slot 43.

[0022] The slide groove 41 is formed as a single groove on the top surface of the rail member 18, and the forward-extending member 21 and the hook member 22 are fitted inside the slide groove so as to be slidable in the front-to-rear direction FR. The configuration of the rail member 18 in this embodiment is one example, and it is of course possible to adopt other configurations, such as having a rail as a single protruding strip like a monorail, and configuring the forward-extending member 21 and the hook member 22 to straddle this rail.

[0023] As shown in FIG. 4, the insertion piece 42 is formed in the shape of a claw that protrudes downward. The upper part of the insertion piece 42 serves as a stopper that prevents the product 46 from falling off the movable plate 17 and from tipping over. The upper part of the insertion piece 42 is further provided with an insertion portion 42A into which a pop label bearing the product price and other information can be inserted. The insertion piece 42 can be inserted into the upright piece 35 (groove) of the movable plate 17 and detached from the upright piece 35 (groove). Therefore, the rail member 18 is configured to be detachable from the movable plate 17, as shown in FIG. 1. Furthermore, the rail member 18 can be positioned at any position on the movable plate 17 in the width direction W.

[0024] The slot 43 is formed on the side surface of the rail member 18 in an elongated manner in the front-to-rear direction FR. This allows the fixed portion 14 (the cross plate 27 and the flat plate 28) to move relatively within this slot 43. In reality, as the movable plate 17 moves in the front-to-rear direction FR, the rail member 18 moves together with it, but the position of the fixed portion 14 does not change. Therefore, as the movable plate 17 moves, the rail member 18 moves smoothly together with the movable plate 17.

[0025] As shown in FIGS. 4 and 13 , the engaging portion 44 is provided in the slot 43 so as to protrude in a plate shape toward the fixed portion 14. The engaging portion 44 is formed to be elongated along the front-rear direction FR. As shown in FIGS. 3 and 13 , when the movable plate 17 is in the second position P2 where it is stored on the rear side, the engaging portion 44 engages with one of the multiple grooves 31 of the fixed portion 14. As shown in FIGS. 9 and 10 , when the movable plate 17 is in the first position P1 where it is pulled out to the front side, the engaging portion 44 is in a position separated from the multiple grooves 31 of the fixed portion 14 and cannot engage with the multiple grooves 31.

[0026] 3 and 4, the anchor portion 32 is formed in a claw shape that protrudes toward the rear direction R, and can tightly engage with the second surface 28B (recess 34) of the fixed portion 14 (flat plate 28). In this state, the rail member 18 is fixed to the fixed portion 14, and the rail member 18 cannot be removed from the fixed portion 14 and the movable plate 17.

[0027] 4 and 9, the expanded diameter portion 45 is formed so that the height dimension of the gap is larger than the location where the engagement portion 44 is provided in the slot 43. In addition, the height dimension of the gap that constitutes the expanded diameter portion 45 is formed larger than the height dimension (thickness dimension) of the fixed portion 14 (flat plate 28). Therefore, when the moving plate 17 is in the first position P1, the expanded diameter portion 45 can accommodate the fixed portion 14 with a gap between them.

[0028] 4 and 5, the forward-advancing member 21 is provided to stand upright from the rail member 18. The forward-advancing member 21 can advance the product 46 by coming into contact with the product 46 from behind.

[0029] The front-extension member 21 is fitted into a slide groove 41 on the top surface of the rail member 18 and is configured to be slidable in the front-to-rear direction FR. The front-extension member 21 is attached to the rail member 18 via a bearing ball 47. The rail member 18 has a recessed portion 48 around the slide groove 41, in which the bearing ball 47 runs in the front-to-rear direction FR. The front-extension member 21 has a base 51 attached directly to the rail member 18, and a swivel portion 52 attached to the base 51 so as to be swivelable. The base 51 has a bearing portion 51B that rotatably supports the reel of the biasing member 23.

[0030] The oscillating portion 52 is rotatably mounted on a shaft 51A mounted on the top of the base 51. The oscillating portion 52 has an upper first piece 52A and a lower second piece 52B. When replenishing products 46, the store manager can use the oscillating portion 52 to lower the forward-pushing member 21 backward. That is, when the store manager presses down on the first piece 52A of the oscillating portion 52 with their hand or a product 46, the oscillating portion 52 rotates around the shaft 51A, and the second piece 52B rises, attempting to push against a nearby product 46. The reaction of the second piece 52B pressing against the product 46 moves the forward-pushing member 21 backward. This allows the store manager to easily lower the forward-pushing member 21 in the rearward direction R with a single touch.

[0031] As shown in FIGS. 4 to 6 , the hook member 22 is formed in a rectangular block shape. The hook member 22 is provided forward of the forward-extending member 21 and below the product 46, and is slidable in the front-to-rear direction FR. The hook member 22 is fitted into the slide groove 41 on the top surface of the rail member 18 and is configured to be slidable in the front-to-rear direction FR. The hook member 22 has a slit 22A into which the tip end 54A of the spiral spring 54 of the biasing member 23 can be inserted and held. The hook member 22 has a hook portion 33 on its underside for hooking onto the second surface 28B (recess 34) of the fixed portion 14 (flat plate 28). The hook member 22 can engage with the fixed portion 14 to restrict movement behind the fixed portion 14 as the movable plate 17 moves, or can be separated from the fixed portion 14.

[0032] The hook member 22 is connected to the front-extending member 21 via a biasing member 23. The biasing member 23 has a cylindrical reel 53, a spiral spring 54 wound around the reel 53, and a tip end 54A of the spiral spring. The spiral spring 54 can be pulled out from around the reel 53, but has a restoring force that causes it to rewind back around the reel 53. Therefore, the biasing member 23 can bias the front-extending member 21 and the hook member 22 so as to bring them closer together.

[0033] As shown in Figure 1, the partition plate 24 has an insertion piece 42 that can be inserted into the upright piece 35 of the movable plate 17. The structure of the insertion piece 42 is similar to that of the insertion piece 42 provided on the rail member 18. The partition plate 24 can divide the movable plate 17 in the front-rear direction FR. The partition plate 24 has an insertion piece 55 on its underside that can be inserted into the groove portion 31.

[0034] Next, the operation of the shelf 10 of this embodiment will be described with reference to Figures 7 to 13. When a store manager wishes to replenish products 46, he or she releases the locking mechanism and pulls out the movable plate 17 in the forward direction F. This moves the movable plate 17 from the second position P2 shown in Figure 1 to the first position P1 shown in Figure 7. In this state, the store manager can replenish new products 46 behind the remaining products 46. When in the first position P1, the forward-extending member 21 remains in contact with the hook member 22 due to the action of the biasing member 23.

[0035] Prior to replenishing products 46, the store manager first moves the forward-extending member 21 to the rearmost position on the rail member 18, as shown in Figures 7 and 8. At this time, because the hook member 22 is not engaged with the fixing portion 14 (flat plate 28), no biasing force is applied to the forward-extending member 21 in the forward direction F. This allows the store manager to easily replenishing products 46 with one hand, without having to hold down the forward-extending member 21.

[0036] In this state, as shown in Figures 9 and 10, the engaging portion 44 is not inserted into the groove portion 31 of the fixed portion 14, and the fixed portion 14 is stored in the expanded diameter portion 45. In this state, as shown by the arrows in Figures 9 and 10, the store manager can move the rail member 18 to any position in the width direction W. Also, in this state, the insertion piece 55 of the partition plate 24 is not inserted into the groove portion 31 of the fixed portion 14, so the store manager can also move the partition plate 24 to any position in the width direction W. This allows the store manager to not only replenish products 46, but also smoothly replace products 46.

[0037] As shown in Figure 8, the store manager replenishes new products 46 behind the remaining products 46. After completing the replenishment of products 46, the store manager moves the movable plate 17 from the first position P1 to the second position P2. At this time, as shown in Figures 8 and 12, the hook members 22 engage with the fixed portion 14 (flat plate 28) as the movable plate 17 moves from the first position P1 to the second position P2. As a result, the hook members 22 move relatively from the rear end portion 17B toward the front end portion 17A on the movable plate 17 (in reality, the movable plate 17 moves backward, and the hook members 22 come to a stop together with the fixed portion 14).

[0038] Meanwhile, the rail member 18 and the forward-extending member 21 move rearward together with the movable plate 17. As a result, the distance between the hook member 22 and the forward-extending member 21 increases, and the biasing member 23 is activated, biasing the forward-extending member 21 in a direction toward the hook member 22 and the fixed portion 14. This causes the forward-extending member 21 to abut against the rear side of the product 46, allowing the product 46 to be advanced forward in the forward direction F within the movable plate 17. As shown in FIGS. 1 and 13 , when the movable plate 17 is in the second position P2, the engagement portion 44 is inserted into the groove 31 of the fixed portion 14, restricting movement of the rail member 18 in the width direction W. Therefore, when the biasing force of the forward-extending member 21 to advance the product 46 is applied, the rail member 18 is prevented from shifting sideways, and the products 46 do not collapse and shift out of place.

[0039] Furthermore, in this state, the anchor portions 32 of the rail members 18 engage with the recesses 34 of the fixed portion 14, preventing the rail members 18 from lifting up from the fixed portion 14. This stabilizes the position of the products 46. Similarly, with regard to the partition plate 24, when the movable plate 17 is in the second position P2, the insertion pieces 55 are inserted into the grooves 31 of the fixed portion 14, restricting the movement of the partition plate 24 in the width direction W. This completes the replenishment of the products 46 and the forward advancement of the replenished products 46.

[0040] According to this embodiment, the following can be said: The product forward-dispensing device includes a movable plate 17 having a fixed portion 14, a front end portion 17A, and a rear end portion 17B, and disposed directly below the fixed portion 14, the movable plate 17 being movable between a first position P1 where the rear end portion 17B overlaps with the fixed portion 14 and a second position P2 where the front end portion 17A overlaps with the fixed portion 14, a rail member 18 disposed on the movable plate 17 and on which a product 46 is placed, and a rail member 18 movable in the front-rear direction FR on the rail member 18. The rail member 18 is provided with a forward-extending member 21 that is arranged to stand upright from the rail member 18 and can advance the product 46 by abutting against the product 46 from the rear side, a hook member 22 that is movable in the front-to-rear direction FR on the rail member 18 at a position below the product 46, and that can engage with the fixed part 14 to restrict the hook member 22 from moving rearward beyond the fixed part 14 or can be separated from the fixed part 14, and a biasing member 23 that biases the forward-extending member 21 and the hook member 22 in a direction that brings them closer to each other.

[0041] According to this configuration, when the movable plate 17 moves from the first position P1 to the second position P2, the hook member 22 can be engaged with the fixed portion 14, thereby restricting the hook member 22 from moving rearward beyond the fixed portion 14. This stops the hook member 22 relative to the moving movable plate 17, rail member 18, and forward-extending member 21. As a result, as the movable plate 17 continues to move from the first position P1 to the second position P2, the distance between the hook member 22 and the forward-extending member 21 increases, which activates the biasing member 23, biasing the forward-extending member 21 and the hook member 22 in a direction that brings them closer together. This causes the forward-extending member 21 to be extended forward relative to the movable plate 17, which generates a forward-extending operating force on the product 46 on the rail member 18, automatically advancing the product 46.

[0042] On the other hand, when the movable plate 17 is in the first position P1, the hook member 22 is separated from the fixed portion 14, allowing the hook member 22 to move freely in the front-to-rear direction FR on the rail member 18. The biasing member 23 causes the hook member 22 to be closest to the forward-extension member 21. Therefore, when the movable plate 17 is in the first position P1, the forward-extension operating force of the forward-extension member 21 is not applied to the products 46. This allows the store manager to move the forward-extension member 21 to a rear position on the movable plate 17 and replenish new products 46 behind the products 46 remaining on the rail member 18. Because replenishment can be performed without the forward-extension operating force of the forward-extension member 21 being applied, there is no need to hold the forward-extension member 21 with one hand while replenishing the products 46 with the other, and the replenishment work of the products 46 can be performed smoothly with just one hand. This allows the replenishment work of the products 46 to be performed efficiently even in a small space that only fits one hand. Alternatively, an efficient restocking operation can be achieved by restocking products 46 with one hand and holding a basket containing stock products 46 with the other hand.

[0043] In this case, the fixed portion 14 has a first surface 28A having a plurality of groove portions 31 extending in the fore-and-aft direction FR, and a second surface 28B opposite the first surface 28A, and extends in a strip shape in the width direction W, and the rail member 18 has a slot 43 capable of accommodating the fixed portion 14, an engagement portion 44 provided on the front side of the slot 43, protruding into the slot 43, and capable of engaging with one of the plurality of groove portions 31 when the movable plate 17 is in the second position P2, and an expanded diameter portion 45 provided on the rear side of the slot 43, capable of accommodating the fixed portion 14 with a gap between it and the fixed portion 14 when the movable plate 17 is in the first position P1.

[0044] According to this configuration, when the movable plate 17 is in the second position P2, the engaging portion 44 is engaged with the groove portion 31, preventing the rail member 18 from moving in the width direction W relative to the movable plate 17. In particular, since the second position P2 is a state in which the products 46 are displayed facing the customer, it is possible to prevent the products 46 from shifting position in the width direction W in this state. Furthermore, at the second position P2, the biasing member 23 generates an operating force that pushes the products 46 forward, making it easy for the position of the products 46 to change. However, with the above configuration, it is possible to prevent the rail member 18 from shifting sideways and stabilize the position of the products 46.

[0045] The rail member 18 has an anchor portion 32 that is provided on the front side of the slot 43 and engages with the second surface 28B of the fixing portion 14.

[0046] According to this configuration, when the movable plate 17 is in the second position P2, in addition to the engagement between the groove 31 and the engagement portion 44, the anchor portion 32 is engaged with the second surface 28B of the fixed portion 14, which prevents the rail member 18 from floating up from the fixed portion 14. This makes it possible to stabilize the posture of the product 46 when the movable plate 17 is in the second position P2.

[0047] Rail member 18 has insertion pieces 42 that can be inserted into and removed from grooves provided in front end portion 17A of movable plate 17. With this configuration, rail member 18 can be attached to and removed from movable plate 17 with a single touch.

[0048] The biasing member 23 is a spring. With this configuration, the biasing member 23 can be realized with simple components.

[0049] Next, a description will be given of modified embodiments of the shelf 10 of this embodiment. In the following modified embodiments and embodiments, differences from the first embodiment will be mainly described, and descriptions of parts common to the first embodiment will be omitted. (Modification of the first embodiment)

[0050] 14 to 17, a shelf 10 of a first modified example will be described. The shelf 10 is an example of a commodity advance-pushing device as defined in the present invention. In this modified example, the configuration of the hook member 22 and the advance-pushing member 21 around it is different from that of the first embodiment, but the other parts are the same as those of the first embodiment.

[0051] 14 and 15, in this modification, the hook member 22 is provided, for example, directly below the forward-extending member 21, but the installation position of the hook member 22 is not limited to this. The installation position of the hook member 22 may be any position below the forward-extending member 21 where it can engage with the fixing portion 14, and may be diagonally below the forward-extending member 21. The hook member 22 can be pulled out from a position below the forward-extending member 21.

[0052] Hook member 22 is formed from a plate material bent into a "J" shape or a "U" shape. Hook member 22 is fixed to the tip of spiral spring 54. In this modification, hook member 22 is formed from a bent plate material that is a separate member, but it may also be formed by bending the tip of spiral spring 54 into a "J" shape or a "U" shape.

[0053] The forward-extending member 21 is fitted into the slide groove 41 on the top surface of the rail member 18 and is configured to be slidable in the front-to-rear direction FR. The forward-extending member 21 has a pair of fitting pieces 56 with an L-shaped cross section that are fitted into the slide groove 41, and a pair of support pieces 57 that are provided so as to protrude inward from the inner surfaces of the pair of fitting pieces 56. The pair of fitting pieces 56 are formed symmetrically with respect to each other.

[0054] The pair of support pieces 57 protrude inward from the lower ends of the pair of fitting pieces 56. The pair of support pieces 57 can support the hook member 22 at a position directly below the forward-extending member 21. In other words, the pair of fitting pieces 56 can hold the hook member 22 hooked thereto in that position, and the action of the spiral spring 54 can prevent the hook member from being wound around the reel 53. The pair of support pieces 57 can also support the hook member 22 so that it can be pulled out in the forward direction F.

[0055] Next, the operation of the shelf 10 of this modified example will be described with reference to Figures 16 and 17. When a store manager wishes to replenish products 46, he or she releases the locking mechanism and pulls out the movable plate 17 in the forward direction F. This moves the movable plate 17 from the second position P2 shown in Figure 17 to the first position P1 shown in Figure 16. In this state, the store manager can replenish new products 46 behind the remaining products 46. When in first position P1, the hook member 21 is located directly below the forward-extending member due to the action of the biasing member 23 and the pair of support pieces.

[0056] Before replenishing products 46, the store manager first moves the forward-extending member 21 to the rearmost position on the rail member 18, as shown in Figure 16. At this time, because the hook member 22 is not engaged with the fixing portion 14 (flat plate 28), no biasing force is applied to the forward-extending member 21 in the forward direction F. This allows the store manager to easily replenishing products 46 with one hand, without having to hold down the forward-extending member 21.

[0057] In this state, as shown in Figure 16, the engaging portion 44 is not inserted into the groove portion 31 of the fixed portion 14, and the fixed portion 14 is stored in the expanded diameter portion 45. In this state, the store manager can move the rail member 18 to any position in the width direction W. Also, in this state, the insertion piece 55 of the partition plate 24 is not inserted into the groove portion 31 of the fixed portion 14, so the store manager can also move the partition plate 24 to any position in the width direction W. This allows the store manager to not only replenish products 46, but also to smoothly replace the products 46.

[0058] As shown in FIG. 16, the store manager replenishes new products 46 behind the remaining products 46. After completing the replenishment of products 46, the store manager moves the movable plate 17 from first position P1 to second position P2. At this time, as shown in FIGS. 16 and 17, the hook members 22 engage with the fixed portion 14 (flat plate 28) as the movable plate 17 moves from first position P1 to second position P2. As a result, the hook members 22 move relatively from the rear end portion 17B toward the front end portion 17A on the movable plate 17 (in reality, the movable plate 17 moves backward, and the hook members 22 come to a stop together with the fixed portion 14).

[0059] Meanwhile, the rail member 18 and the forward-extending member 21 move rearward together with the movable plate 17. As a result, the distance between the hook member 22 and the forward-extending member 21 increases, and the biasing member 23 is activated, biasing the forward-extending member 21 in a direction toward the hook member 22 and the fixed portion 14. This causes the forward-extending member 21 to abut against the rear side of the product 46, allowing the product 46 to be advanced forward in the forward direction F within the movable plate 17. As shown in FIG. 17 , when the movable plate 17 is in the second position P2, the engagement portion 44 is inserted into the groove portion 31 of the fixed portion 14, restricting the movement of the rail member 18 in the width direction W. Therefore, when the biasing force of the forward-extending member 21 to advance the product 46 is applied, the rail member 18 is prevented from shifting sideways, and the products 46 do not collapse and shift out of place.

[0060] Furthermore, in this state, the anchor portions 32 of the rail members 18 engage with the recesses 34 of the fixed portion 14, preventing the rail members 18 from lifting up from the fixed portion 14. This stabilizes the position of the products 46. Similarly, with regard to the partition plate 24, when the movable plate 17 is in the second position P2, the insertion pieces 55 are inserted into the grooves 31 of the fixed portion 14, restricting the movement of the partition plate 24 in the width direction W. This completes the replenishment of the products 46 and the forward advancement of the replenished products 46.

[0061] According to this embodiment, the following can be said: The shelf 10 has a fixed portion 14, a front end 17A, and a rear end 17B, and is equipped with a movable plate 17 provided directly below the fixed portion 14, the movable plate 17 being movable between a first position P1 where the rear end 17B overlaps with the fixed portion 14 and a second position P2 where the front end 17A overlaps with the fixed portion 14, a rail member 18 provided on the movable plate 17 and on which a product 46 is placed, a front-extension member 21 that is movable in the front-to-rear direction FR on the rail member 18 and stands up from the rail member 18, and that can advance the product 46 by abutting against the product 46 from the rear side, a hook member 33 that is provided so as to be retractable from the front-extension member 21, and that can engage with the fixed portion 14 to restrict movement behind the fixed portion 14 and can be separated from the fixed portion 14, and a biasing member 23 that biases the front-extension member 21 and the hook member 33 in a direction toward each other.

[0062] With this configuration, the hook member 22 can be stopped relative to the moving plate 17, rail member 18, and forward-extending member 21 as they move from the first position P1 toward the second position P2. As a result, the biasing member 23 is activated to bias the forward-extending member 21 and the hook member 22 in a direction that brings them closer together. This causes the forward-extending member 21 to be extended forward relative to the moving plate 17, which generates a forward-extending operating force on the product 46 on the rail member 18, causing the product 46 to be automatically extended forward.

[0063] On the other hand, when the movable plate 17 is in the first position P1, the hook member 22 is separated from the fixed portion 14, and therefore the hook member 22 can move freely in the front-to-rear direction FR on the rail member 18. The action of the biasing member 23 causes the hook member 22 to be in the position closest to the forward-extension member 21. Therefore, when the movable plate 17 is in the first position P1, the forward-extension operating force of the forward-extension member 21 is not applied to the products 46. Therefore, the store manager can move the forward-extension member 21 to a rear position on the movable plate 17 and replenish new products 46 behind the products 46 remaining on the rail member 18. Because replenishment can be performed without the forward-extension operating force of the forward-extension member 21 being applied, there is no need to hold the forward-extension member 21 with one hand while replenishing the products 46 with the other, and the replenishment work of the products 46 can be performed smoothly with just one hand. [Second embodiment]

[0064] A shelf 10 according to a second embodiment will be described with reference to Figures 18 to 21. As shown in Figure 18, the shelf 10 includes a base 11, a pair of frames 12 standing upright from both rear and opposite ends of the base 11, a back panel 13 extending between the pair of frames 12, a pair of brackets 15 fixed to each of the pair of frames 12, a shelf board 61 fixedly provided between the pair of brackets 15, and a display box 62 provided on the shelf board 61. In this embodiment, the display box 62 can be attached to and detached from the shelf board 61. The display box 62 is an example of a product front-dispense device as defined in the present invention.

[0065] As shown in Figures 19 and 20, the display box 62 comprises a box main body 63, a fixed portion 14 spanning between a pair of side walls 63A of the box main body 63, a movable plate 17 provided on the bottom wall 63B of the box main body 63 and capable of being pulled out in the forward direction F or pushed in in the rearward direction R, a rail member 18 provided on the movable plate 17, a forward-extension member 21 movable in the front-to-rear direction FR on the rail member 18, a hook member 22 movable in the front-to-rear direction FR on the rail member 18, a biasing member 23 biasing the forward-extension member 21 and the hook member 22 in a direction that brings them closer together, and a partition plate 24 that divides the movable plate 17 along the front-to-rear direction FR.

[0066] The fixed portion 14 includes a metal cross plate 27 extending between the pair of side walls 63A and a resin flat plate 28 attached to the upper surface of the cross plate 27. The cross plate 27 and the flat plate 28 are provided across substantially the entire width of the movable plate 17 and are formed in a strip shape extending elongatedly in the width direction W. The flat plate 28 is detachably fixed to the cross plate 27 by engaging with a claw or the like. The flat plate 28 has a first surface 28A and a second surface 28B opposite the first surface 28A. The second surface 28B of the flat plate 28 abuts against the cross plate 27. The first surface 28A of the flat plate 28 has a plurality of grooves 31 extending in the front-rear direction FR. The flat plate 28 further has a recess 34 at the front end of the second surface 28B for hooking onto an anchor portion 32 of the rail member 18 and a hook portion 33 of the hook member 22, which will be described later.

[0067] The movable plate 17 is provided in a flat plate shape. The movable plate 17 has a standing piece 35 with a U-shaped cross section at its front end 17A, into which the insertion piece 42 of the rail member 18 or the insertion piece 42 of the partition plate 24 can be inserted. In this embodiment, the standing piece 35 serves as a finger hook for the store manager when pulling the movable plate 17 forward. The store manager can pull the movable plate 17 from the second position P2 to the first position P1 by putting their finger on the standing piece 35 and pulling it forward.

[0068] The rail member 18, the forward-extending member 21, the hook member 22, the biasing member 23, and the partition plate 24 have the same configurations as those in the first embodiment. The rail member 18 is configured to be detachable from the moving plate 17, as shown in FIG.

[0069] 18 to 21, the operation of the shelf 10 and display box 62 of this embodiment will be described. When a store manager wishes to replenish products 46, he or she pulls out the movable plate 17 toward the front. This moves the movable plate 17 from the second position P2 shown in FIGS. 18 and 19 to the first position P1 shown in FIG. 16. In this state, the store manager can replenish new products 46 behind the remaining products 46. The forward-extending member 21 remains in contact with the hook member 22 due to the action of the biasing member 23.

[0070] Prior to replenishing products 46, the store manager first moves the forward-extending member 21 to the rearmost position on the rail member 18, as shown in FIG. 20 . At this time, because the hook member 22 is not engaged with the fixed portion 14 (flat plate 28), no biasing force is applied to the forward-extending member 21 in the forward direction F. In this state, the engagement portion 44 is not inserted into the groove portion 31 of the fixed portion 14, and the fixed portion 14 is housed within the expanded diameter portion 45. In this state, the store manager can move the rail member 18 to any position in the width direction W. Furthermore, in this state, the insertion piece 55 of the partition plate 24 is not inserted into the groove portion 31 of the fixed portion 14, so the store manager can also move the partition plate 24 to any position in the width direction W. This allows the store manager to smoothly not only replenishing products 46 but also replacing products 46.

[0071] As shown in FIG. 20, the store manager replenishes new products 46 behind the remaining products 46. After completing the replenishment of products 46, the store manager moves the movable plate 17 from the first position P1 to the second position P2. At this time, as shown in FIG. 17, the hook members 22 engage with the fixed portion 14 (flat plate 28) as the movable plate 17 moves from the first position P1 to the second position P2. As a result, the hook members 22 move relatively on the movable plate 17 from the rear end portion 17B toward the front end portion 17A (in reality, the movable plate 17 moves backward, and the hook members 22 come to a stop together with the fixed portion 14).

[0072] Meanwhile, the rail member 18 and the forward-advancing member 21 move rearward together with the movable plate 17. As a result, the distance between the hook member 22 and the forward-advancing member 21 increases, and the biasing member 23 is activated, biasing the forward-advancing member 21 in a direction toward the hook member 22 and the fixed portion 14. This causes the forward-advancing member 21 to abut against the rear side of the product 46, allowing the product 46 to be advanced within the movable plate 17. As shown in FIG. 21 , when the movable plate 17 is in the second position P2, the engagement portion 44 is inserted into the groove portion 31 of the fixed portion 14, restricting the movement of the rail member 18 in the width direction W. Therefore, when a differential force is applied by the forward-advancing member 21 to advance the product 46, the rail member 18 is prevented from shifting sideways, preventing the product 46 from collapsing and shifting. Similarly, when the movable plate 17 is in the second position P2, the insertion piece 55 of the partition plate 24 is inserted into the groove portion 31 of the fixed portion 14, thereby restricting the movement of the partition plate 24 in the width direction W.

[0073] Therefore, this embodiment also provides the same effects as the above-described embodiment.

[0074] Next, a description will be given of a modified example of the second embodiment. In the following embodiment, differences from the second embodiment will be mainly described, and a description of parts common to the second embodiment will be omitted. (First modified example of the second embodiment)

[0075] 22 to 24, a shelf 10 and a display box 62 according to a first modified example of the second embodiment will be described. In this modified example, the length of the fixing portion 14 in the front-rear direction FR differs from that of the second embodiment. Also, the shape of a portion of the rail member 18 differs from that of the second embodiment. The display box 62 is an example of a commodity forward-dispatch device according to the present invention.

[0076] The fixed portion 14 has a metal cross plate 27 that spans between the pair of side walls 63A, and a resin flat plate 28 that is attached to the upper surface of the cross plate 27. The cross plate 27 and the flat plate 28 are provided across approximately the entire width of the movable plate 17 in the width direction W. Furthermore, the cross plate 27 and the flat plate 28 are also provided across approximately the entire width of the movable plate 17 in the front-rear direction FR. Therefore, when the movable plate 17 is in the rear second position P2, the fixed portion 14 can cover approximately the entire upper surface of the movable plate 17.

[0077] The flat plate 28 is detachably fixed to the cross plate 27 by engaging a claw or the like. The flat plate 28 has a first surface 28A and a second surface 28B opposite to the first surface 28A. The second surface 28B of the flat plate 28 abuts against the cross plate 27. The first surface 28A of the flat plate 28 has a plurality of grooves 31 extending in the front-rear direction. The flat plate 28 further has recesses 34 at the front end of the second surface 28B for receiving anchor portions 32 of the rail member 18, which will be described later, and hook portions 33 of the hook member 22, which will be described later.

[0078] The rail member 18 has a slide groove 41, an insertion piece 42, a slot 43, an engagement portion 44, an anchor portion 32, and an expanded diameter portion 45. The configurations of the slide groove 41, the insertion piece 42, the engagement portion 44, and the anchor portion 32 are the same as those in the second embodiment. In this modification, the slot 43 and the expanded diameter portion 45 continue to the rear end of the rail member 18.

[0079] 22 to 24, the operation of the shelf 10 and display box 62 of this modified example will be described. When a store manager wishes to replenish products 46, he or she pulls out the movable plate 17 toward the front. This moves the movable plate 17 from the second position P2 shown in FIG. 22 to the first position P1 shown in FIG. 23. In this state, the store manager can replenish new products 46 behind the remaining products 46. The forward-extending member 21 remains in contact with the hook member 22 due to the action of the biasing member 23.

[0080] Prior to replenishing products 46, the store manager first moves the forward-extending member 21 to the rearmost position on the rail member 18, as shown in FIG. 23 . At this time, because the hook member 22 is not engaged with the fixed portion 14 (flat plate 28), no biasing force is applied to the forward-extending member 21 in the forward direction F. In this state, the engagement portion 44 is not inserted into the groove portion 31 of the fixed portion 14, and the fixed portion 14 is housed within the expanded diameter portion 45. In this state, the store manager can move the rail member 18 to any position in the width direction W. Furthermore, in this state, the insertion piece 55 of the partition plate 24 is not inserted into the groove portion 31 of the fixed portion 14, so the store manager can also move the partition plate 24 to any position in the width direction W. This allows the store manager to smoothly not only replenishing products 46 but also replacing products 46.

[0081] As shown in FIG. 23, the store manager replenishes new products 46 behind the remaining products 46. After completing the replenishment of products 46, the store manager moves the movable plate 17 from the first position P1 to the second position P2. At this time, as shown in FIG. 24, as the movable plate 17 moves from the first position P1 to the second position P2, the hook member 22 engages with the front end (recess 34) of the fixed part 14 (flat plate 28). As a result, the hook member 22 moves relatively on the movable plate 17 from the rear end 17B toward the front end 17A (in reality, the movable plate 17 moves backward, and the hook member 22 comes to a stop together with the fixed part 14).

[0082] Meanwhile, the rail member 18 and the forward-advancing member 21 move rearward together with the movable plate 17. As a result, the distance between the hook member 22 and the forward-advancing member 21 increases, and the biasing member 23 is activated, biasing the forward-advancing member 21 in a direction toward the hook member 22 and the front end of the fixed portion 14. This causes the forward-advancing member 21 to abut against the rear side of the product 46, allowing the product 46 to be advanced within the movable plate 17. As shown in FIG. 21 , when the movable plate 17 is in the second position P2, the engagement portion 44 is inserted into the groove portion 31 of the fixed portion 14, restricting the movement of the rail member 18 in the width direction W. Therefore, when a differential force is applied by the forward-advancing member 21 to advance the product 46, the rail member 18 is prevented from shifting sideways, preventing the product 46 from collapsing and shifting. Similarly, when the movable plate 17 is in the second position P2, the insertion piece 55 of the partition plate 24 is inserted into the groove portion 31 of the fixed portion 14, thereby restricting the movement of the partition plate 24 in the width direction W.

[0083] Therefore, this embodiment also provides the same effects as the above-described embodiment. (Second Modification of the Second Embodiment)

[0084] 25 to 28, a shelf 10 and a display box 62 according to a second modified example of the second embodiment will be described. This modified example differs from the second embodiment in that the display box 62 is partitioned to accommodate individual boxes 71. In this modified example, a fixing portion 14 is provided for each individual box 71. Furthermore, in this modified example, a partition plate 24 is not provided. The display box 62 is an example of a product forward-dispatch device according to the present invention.

[0085] The display box 62 comprises a box main body 63, individual boxes 71 that can be pulled out individually in the front-to-rear direction FR relative to the box main body 63, a plurality of fixing portions 14 fixed to the bottom wall 63B of the box main body 63, a rail member 18 provided on the bottom wall 63B of the individual box 71, a forward-extending member 21 that can move in the front-to-rear direction FR on the rail member 18, a hook member 22 that can move in the front-to-rear direction FR on the rail member 18, and a biasing member 23 that biases the forward-extending member 21 and the hook member 22 in a direction in which they approach each other.

[0086] The individual box 71 has a bottom wall 63B and a side wall 63A surrounding the bottom wall 63B. The bottom wall 63B has a narrow through-hole 72 in the center that is elongated in the front-to-rear direction. The bottom wall 63B of the individual box 71 is an example of the movable plate referred to in the present invention.

[0087] The fixing portion 14 has a flat plate 28 and leg portions 73 that protrude downward from the flat plate 28 and are fixed to the box main body 63. The flat plate 28 and leg portions 73 of the fixing portion 14 are integrally molded from a resin material. The fixing portion 14 is formed in a strip shape that is long and narrow in the width direction W. The fixing portion 14 is provided so as to span substantially the entire width of the individual box 71 in the width direction W. The leg portions 73 are passed through through holes 72 and fixed to insertion holes 74 of the box main body 63.

[0088] The flat plate 28 has a first surface 28A and a second surface 28B opposite to the first surface 28A. Legs 73 protrude from the second surface 28B of the flat plate 28. The flat plate 28 has a plurality of grooves 31 extending in the front-rear direction FR on the first surface 28A. The flat plate 28 further has recesses 34 on the front end of the second surface 28B for receiving anchor portions 32 (described later) of the rail member 18 and hook portions 33 (described later) of the hook member 22.

[0089] The operation of the shelf 10 and display box 62 of this modified example will be described with reference to Figures 25 to 28. When the store manager wishes to replenish products 46, he pulls out the individual box 71 towards the front. This moves the individual box 71 (movable plate) from the second position P2 shown in Figure 25 to the first position P1 shown in Figure 27. In this state, the store manager can replenish new products 46 behind the remaining products 46. The forward-extending member 21 remains in contact with the hook member 22 due to the action of the biasing member 23.

[0090] Prior to replenishing products 46, the store manager first moves the front-extending member 21 to the rearmost position on the rail member 18, as shown in FIG. 27. At this time, because the hook member 22 is not engaged with the fixed portion 14 (flat plate 28), no biasing force is applied to the front-extending member 21 in the forward direction F. In this state, the engagement portion 44 is not inserted into the groove portion 31 of the fixed portion 14, and the fixed portion 14 is housed within the expanded diameter portion 45. In this state, the store manager can move the rail member 18 to any position in the width direction W within the individual box 71.

[0091] As shown in FIG. 27, the store manager replenishes new products 46 behind the remaining products 46. After completing the replenishment of the products 46, the store manager moves the individual box 71 (movable plate) from the first position P1 to the second position P2. At this time, as shown in FIG. 28, as the individual box 71 moves from the first position P1 to the second position P2, the hook member 22 engages with the front end (recess 34) of the fixing part 14 (flat plate 28). As a result, the hook member 22 moves relatively above the individual box 71 from the rear end 17B toward the front end 17A (in reality, the individual box 71 moves backward, and the hook member 22 comes to a stop together with the fixing part 14).

[0092] Meanwhile, the rail member 18 and the forward-advancing member 21 move rearward together with the individual box 71 (movable plate). This increases the distance between the hook member 22 and the forward-advancing member 21, activating the biasing member 23 and biasing the forward-advancing member 21 toward the hook member 22 and the front end of the fixed portion 14. This causes the forward-advancing member 21 to abut against the rear of the product 46, allowing the product 46 to be advanced forward within the individual box 71. As shown in FIG. 28 , when the individual box 71 is in the second position P2, the engaging portion 44 is inserted into the groove 31 of the fixed portion 14, restricting the rail member 18 from moving in the width direction W. Therefore, when a differential force acts on the forward-advancing member 21 to advance the product 46, the rail member 18 is prevented from shifting sideways, preventing the product 46 from collapsing and shifting out of position. In this embodiment, products 46 can be replenished in each individual box 71.

[0093] Therefore, this embodiment also provides the same effects as the above-described embodiment.

[0094] The above-described embodiment can be implemented with various further substitutions and modifications, and it goes without saying that the above-described different embodiments can be appropriately combined to form a single invention. [Explanation of symbols]
