Description

[Technical Field]

[0001] The present invention relates to a product advancement device that advances products. [Background technology]

[0002] For example, an automatic product forward-pushing display shelf is known (see, for example, Patent Document 1). In this display shelf, products can be automatically pushed forward by moving the shelf back and forth. That is, a store manager can move a product forward by moving the movable shelf from its normal position to its pulled-out position, and then move it back to its normal position and then to its pulled-out position again, thereby securing space behind the pushed-out product for new products. In this way, after pushing the products remaining on the shelf forward, the store manager can secure space behind the remaining products on the shelf by manually pushing the push-out member backward as necessary, and then restocking the products.

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. [Embodiment]

[0015] A shelf 10 according to an 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. 9, 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. 9, 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 (see FIG. 8).

[0021] As shown in Fig. 1, the rail member 18 is placed on the movable plate 17 when in use. As shown in Fig. 8, 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. In other words, the rail member 18 extends in the front-to-rear direction FR.

[0022] As shown in Figure 4, the rail member 18 has a slide groove 41 on its top surface extending in the fore-and-aft direction FR, an insertion piece 42 on its front end, a slot 43 on its side capable of accommodating the fixing portion 14 (cross plate 27 and flat plate 28), engagement portions 44 on the middle and front sides of the slot 43 in the fore-and-aft direction FR, an anchor portion 32 on the frontmost side of the slot 43, and an expanded diameter portion 45 on the rear side of the slot 43.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] As shown in FIG. 4, 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 FIG. 3, 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.

[0027] 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.

[0028] 4, 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.

[0029] 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 abutting against the product 46 from behind.

[0030] The forward-extending 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 forward-extending 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, along which the bearing ball 47 travels in the front-to-rear direction FR. The forward-extending member 21 has a base 51 that is directly attached to the rail member 18, and a oscillating portion 52 that is attached to a first shaft portion 51A of the base 51 so as to be rotatable in a seesaw shape. The base 51 is capable of advancing and retreating on the rail member 18. The base 51 has a bearing portion 51B that rotatably supports a reel 53 of the biasing member 23.

[0031] The base 51 has a first shaft portion 51A at the end (top) opposite to the end connected to the rail member 18. In this embodiment, the first shaft portion 51A is provided on the base 51, but this is not limiting. Instead of the first shaft portion 51A, a first bearing having a configuration similar to that of a second bearing 52C described below may be provided at the position where the first shaft portion 51A is provided.

[0032] The oscillating portion 52 is rotatably provided on a first shaft portion 51A provided on the top of the base portion 51. As shown in FIGS. 5 to 7, the oscillating portion 52 has an upper first piece 52A, a lower second piece 52B, and a second bearing 52C that engages with the first shaft portion 51A. The second bearing 52C is arch-shaped (hook-shaped) so as to surround the first shaft portion 51A, and has an opening 52CA in part thereof for allowing the first shaft portion 51A to pass through. Note that if the base portion 51 is provided with a first bearing, the oscillating portion 52 may be provided with a second shaft portion that fits within and engages with the first bearing. In this case, the second shaft portion has the same configuration as the first shaft portion 51A.

[0033] As shown in Fig. 6, the first piece 52A extends obliquely from the first shaft portion 51A so that the installation height increases as it extends rearward. Alternatively, instead of the above configuration, the first piece 52A may extend from the first shaft portion 51A in the rear direction R along a substantially horizontal direction, as shown by the two-dot chain line in the same figure. Alternatively, instead of the above configuration, the first piece 52A may extend upward from the first shaft portion 51A along a substantially vertical direction, as shown by the two-dot chain line in the same figure. As shown in Fig. 7, the first piece 52A is formed in the shape of a thin, flat plate.

[0034] The second piece 52B extends downward. As shown in FIG. 7, the second piece 52B is thicker and heavier than the first piece 52A. That is, the second piece 52B is formed in a thick, flat plate shape. When stationary, the second piece 52B abuts against the front side of the base 51. The oscillating unit 52 can rotate between a first position S1 in which the second piece 52B extends downward, as shown in FIGS. 6 and 10, and a second position S2 in which the second piece 52B rises and presses the product 46 from the rear side as the first piece 52A is pressed down, as shown in FIG. 11. Furthermore, due to the balance of weight, in which the second piece 52B is heavier than the first piece 52A, the oscillating unit 52 can automatically return to the first position S1 when the pressing down on the first piece 52A is released from the second position S2.

[0035] In this embodiment, the oscillating portion 52 is configured to return from the second position S2 to the first position S1 due to its own weight, but this is not limited to this configuration. For example, it is also possible to interpose a tension spring between the base 51 and the oscillating portion 52, and to return from the second position S2 to the first position S1 due to the biasing force of this tension spring.

[0036] 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 the 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.

[0037] 5, the oscillating unit 52 is detachable from the base 51. However, a larger oscillating unit may be prepared depending on the size of the product 46, and may be replaced with the original oscillating unit 52. Therefore, when a large product 46 is to be displayed, the store manager can install a correspondingly larger oscillating unit to prevent the oscillating unit from being hidden behind the product 46.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] Next, the operation of the shelf 10 of this embodiment will be described with reference to Figures 8 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 Figures 1 and 8 to the first position P1 shown in Figures 9 and 10. 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.

[0042] 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 store manager can lower the forward-extending member 21 (base portion 51) rearward by rotating the oscillating portion 52 in a seesaw manner, as shown in Figures 10 and 11. That is, when the store manager presses down on the first piece 52A using his or her hand or the product 46 itself, the second piece 52B of the oscillating portion 52 moves from a first position S1 in which it extends downward as shown in Figure 10 to a second position S2 in which it is raised as shown in Figure 11.

[0043] This allows the forward-advancing member 21 (base 51 and oscillating portion 52) to be lowered rearward by utilizing the reaction force of the pressing force of the second piece 52B pushing against the rear side of the product 46. When the store manager releases the pressure on the first piece 52A, the second piece 52B returns from the second position S2 to the first position S1 due to its own weight. As a result, as shown in FIG. 12 , a space is created between the existing product 46 and the forward-advancing member 21 (base 51 and oscillating portion 52), and new products 46 can be replenished in this space. In this way, the store manager can efficiently perform the work of replenishing products without having to manually lower the base 51 in the rearward direction R.

[0044] 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, 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.

[0045] After the replenishment of products 46 is completed, the store manager moves movable plate 17 from first position P1 to second position P2. At this time, as shown in FIG. 13 , hook member 22 engages with fixed portion 14 (flat plate 28) while movable plate 17 is moving from first position P1 to second position P2. As a result, hook member 22 moves relatively on movable plate 17 from rear end portion 17B toward front end portion 17A (in reality, movable plate 17 moves backward, and hook member 22 comes to a stop together with fixed portion 14).

[0046] 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.

[0047] 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.

[0048] According to this embodiment, the following can be said: The product advancement device includes a rail member 18 that extends in the front-to-rear direction FR and on which a product 46 is placed, a base 51 that is movable back and forth on the rail member 18 and has either a first shaft portion 51A or a first bearing at an end opposite to the end connected to the rail member 18, and an oscillating part 52 that has either a second bearing 51B that engages with the first shaft portion 51A or a second shaft portion that engages with the first bearing and is rotatable in a seesaw manner relative to the base 51 around either the first shaft portion 51A or the first bearing, the oscillating part 52 having a first piece 52A that extends rearward from either the first shaft portion 51A or the first bearing and a second piece 52B that extends downward from either the first shaft portion 51A or the first bearing and can abut against the product 46 from behind.

[0049] The product advancement device also includes a rail member 18 that extends in the front-to-rear direction FR and on which the product 46 is placed, a base 51 that can move back and forth on the rail member 18, the base 51 having either a first shaft portion 51A or a first bearing at the end opposite the end that connects to the rail member 18, and a swivel portion 52 that has either a second bearing 51B that engages with the first shaft portion 51A or a second shaft portion that engages with the first bearing and can rotate in a seesaw manner relative to the base 51 around either the first shaft portion 51A or the first bearing, the swivel portion 52 having a first piece 52A that extends upward from either the first shaft portion 51A or the first bearing and a second piece 52B that extends downward from either the first shaft portion 51A or the first bearing and can abut against the product 46 from the rear.

[0050] Conventionally, when replenishing products 46 behind existing products 46, the store manager would manually push the base 51 backward to create space behind the existing products 46 and then replenishing the products 46. With the above-described configuration, the store manager can lower the base 51 backward by utilizing the reaction force of the pressing force (rotational force) of the oscillating portion 52. Therefore, the store manager can, for example, while holding the product 46, rotate the oscillating portion 52 with the hand holding the product 46. This allows the store manager to easily lower the base 51 backward with one hand, making it extremely easy to replenishing new products 46 behind the existing products 46.

[0051] First piece 52 extends diagonally so that its installation height increases toward the rear. With this configuration, the store manager can not only rotate oscillating section 52 by hand, but also rotate oscillating section 52 using the products 46 to be replenished. This eliminates the need for the store manager to let go of the products 46 in order to lower base 51 rearward, making the task of replenishing products 46 even more efficient.

[0052] The oscillating portion 52 can rotate between a first position S1 in which the second piece 52B extends downward and a second position S2 in which the second piece 52B rises when the first piece 52A is pushed down, pressing against the product 46 from the rear, and can return from the second position S2 to the first position S1 when the first piece 52A is released from being pushed down.

[0053] According to this configuration, when replenishing multiple products 46, even if the swivel unit 52 is rotated continuously, the swivel unit 52 automatically returns from the second position S2 to the first position S1, allowing the store manager to carry out the replenishing work of the products 46 extremely efficiently.

[0054] When the pressure on the first piece 52A is released, the oscillating portion 52 returns from the second position S2 to the first position S1 under its own weight. With this configuration, a structure in which the oscillating portion 52 automatically returns from the second position S2 to the first position S1 can be realized with an extremely simple configuration.

[0055] The oscillating unit 52 is detachable from the base 51. With this configuration, it is possible to attach an oscillating unit 52 of an optimal size depending on the size of the product 46, for example. This allows the store manager to more efficiently replenish the products 46.

[0056] The above-described embodiment can be implemented with various further substitutions and modifications. [Explanation of symbols]
